In general, the hose (H) is molded and then cut to a prescribed length and then put on the market. At this time, the hose cutter for cutting the hose H includes the following configuration.

A frame 100 configured to support the upper surface of the frame 100 is formed and an upper plate 110 constituted by a hole 115 attached to the upper end of the frame 100 is formed, The pressing portion 200 is configured to press the hose H which is fixed to the hose 110 and passes above the hole 115. [ The supporter S is disposed on both sides of the hole 115 and protrudes upward so as to support the hose H when the pressing portion 200 presses the hose H. In addition, And a cutter 300 for cutting the hose H pressed by the pressing portion 200 since it is received in the frame 100 and rotates.

The pressure unit 200 is supported by the upper plate 110 to constitute a fluid cylinder 210 in which the rod 213 is directed to the hole 115. The pressure cylinder 200 is fixed to the rod 213, A compression block 220 configured to pressurize is constructed. And a gap 223 penetrating front and rear of the compression block 220 and opening downward to allow the cutter 300 to rotate when it is rotated.

In order to support the fluid cylinder 210 on the upper plate 110, the support block 201 is fixed to the upper plate 110 and has an inclined surface 203 inclined downward toward the front. The guiding block 205 is fixed to the inclined surface 203 to guide the transportation of the rod 213 of the fluid cylinder 210. A guide shaft 207 is fixed to the compression block 220 and penetrates the guide block 205. The fluid cylinder 210 is fixed to the upper surface of the guide block 205 and a rod 213 And is fixed to the compression block 220 through the guide block 205. The guide shaft 207, the rod 213, and the compression block 220 are formed to be parallel to the inclined surface 203.

According to the present invention, in the general hose cutter, since the hose is marked (M) when the hose H is cut by the cutter 300, it is possible to produce the hose H which is easily connected to the nipple .

To this end, the present invention is configured as follows.

As shown in FIGS. 5 and 6, each insertion groove 221 is formed so as to extend from the left and right outer sides S and T of the compression block 220 to the gap 223 and open downward. The block-shaped slider 230 is configured to be inserted into the insertion groove 221 and formed with a lower groove 233, which is opened downward, and ink is supplied from the outside to the lower groove 233, . And an adjusting unit 240 mounted on the compression block 220 and adapted to feed the slider 230.

7, the insertion groove 221 is formed with a protrusion 222 protruding from the opposite inner side 225, and is formed along the longitudinal direction of the insertion groove 221 with a blade shape. The slider 230 has a slider groove 239 that penetrates through the slider 230 so as to allow the protrusion 222 to pass through the front face 237 and the rear face 238 that are in close contact with the inner face 225, . Therefore, the slider 230 is hooked on the protrusion 222 and is capable of reciprocatingly sideways without detaching downward.

The lower groove 233 formed at the lower portion of the slider 230 is formed in a shape of a lower surface of the compression block 220 so as to penetrate through the left and right chambers. Therefore, there is an advantage that the hose H of various diameters can be compressed.

Also, as shown in FIG. 8, the insertion groove 221 is formed to be inclined downward toward the gap 223. The protrusion 222 is also formed to be inclined downward toward the gap 223 in parallel with the insertion groove 221. 6, the lower groove 233 of the both-side slider 230 is formed in a V-shape so that the hose H is bent upward when compressing the hose H, And the cutter 300 is rotated to cut the bent lower portion of the hose H, that is, the bent and convex portion, so that the cut surface can be cut horizontally without being inclined. If the hose H is cut with the cutter 300 without bending the hose H, the hose H is bent toward the cutter 300, and the cut surface is inclined. This idea can be understood by anyone who is the subject of the invention, so a detailed explanation will be omitted.

The configuration of the adjusting unit 240 will be described with reference to FIGS. 6 to 8. FIG.

The transport block 243 and the slider 230 are disposed on the left and right sides of the compression block 220 and configured to be mounted on the compression block 220 so that they can be transported in the left and right direction. Respectively. A rail 241 attached to the front surface Q of the compression block 220 is formed so that the compression block 220 can be conveyed. A guider 242 attached to the block 243 is constructed.

In addition, a tapped hole 246 through which the respective transfer blocks 243 are laterally formed is formed, and a screw shaft 247 to be fastened to the tapped hole 246 is formed. One side of the tapped hole 246 is a left side thread and the other side is a right side thread. The screw shaft 247 is formed with a right screw on one side and a right screw on the other side so that the screw shaft 247 is tightened to the tapped hole 246. Accordingly, when the screw shaft 247 is rotated in the forward and reverse directions, the transfer blocks 243 on both sides are configured to approach the inner side and then to move away from the outer side. Therefore, the slider 230 is also configured to cooperate with the transport block 243.

However, since the insertion block 221 is formed to be inclined downward toward the gap 223, the slider 230 is moved along the insertion groove 221 It should be sloped. The transfer block 243 and the slider 230 are connected to each other so that the transfer block 243 is formed with a tapped hole 244 vertically penetrating the trough hole 244, And a bolt 245 connected to rotate on the upper surface of the base plate 230. Therefore, when the conveying block 243 is conveyed inward, the bolt 245 is tightened so that the slider 230 is lowered. On the contrary, when the conveying block 243 is conveyed outward, the bolt 245 is loosened, (230) is raised. With this configuration, the slider 230 is moved obliquely along the insertion groove 221.

8, a flange C is formed around the lower end of the bolt 245 and a hole H in which the flange C is received is inserted into the slider 230 And the hole H is formed to have a step B at which the flange C is caught, so that the bolt 245 can rotate without being detached.

The conveying block 243 is formed as an L-shaped block and includes a front block E attached to the guider 242 and a rear block E extending rearward from the rear surface of the front block E positioned below the rail 241 And block G. FIG. The tapped hole 246 penetrates the side surface of the front block E and the tapped hole 244 passes through the upper and lower surfaces of the rear block G. [ Accordingly, the bolt 245 is configured not to be interfered with by the rail 241.

8, the ink is supplied to the lower groove 233 as follows. A through hole 235 is formed at the outer surface of the slider 230 to connect to the lower groove 233 and a through hole 235 is formed at the end U of the through hole 235, And the ink hose 260 connected to the end portion R positioned on the outer surface of the slider 230 is formed in the through hole 235. [

The ink nozzle 250 includes a pipe 251 that is inserted into the end portion U and opens upward and downward and a ring-shaped inner flange 253 formed inside the pipe 251 do. A compression spring 255 which is supported by the lower surface of the inner flange 253 and faces downward is formed and a ball 257 disposed at the lower end of the compression spring 255 is formed. In addition, the lower end of the pipe 251 is formed so as to prevent the ball 257 from coming off. Accordingly, when the ball 257 is compressed, the lower end of the pipe 251 is opened, and when the compression is released, the ball 257 protrudes to close the lower end of the pipe 251. It is preferable that only the ball 257 is exposed downward when the ink nozzle 250 is inserted into the through hole 235. With this structure, the entire surface of the lower groove 233 can pressurize the hose H efficiently.

Hereinafter, an operation example of the marking hose cutter 90 according to the present invention will be described.

5, when the compression block 220 is lifted by the operation of the fluid cylinder 210, the screw shaft 247 is rotated in the forward and reverse directions to move the ink nozzle 250 mounted on the both side sliders 230 To match the prescribed marking (M) point set in the hose (H). As described above, the present invention has an advantage that the point of marking M can be varied depending on the type of the hose H. At this time, the conveying block 243 is horizontally conveyed along the rail 241, but the slider 230 can be inclined along the inclined insertion groove 221 by the normal rotation of the bolt 245. That is, when the conveying block 243 is conveyed inward, the bolt 245 is tightened to lower the slider 230, and conversely when the conveying block 243 is conveyed outward, the bolt 245 is loosened, So that the slider 230 can be moved along the slant insertion groove 221. The screw shaft 247 is divided into a left screw and a right screw and the corresponding one of the tapped holes 246 of the slider 230 is also formed of a left screw and a right screw, Are collected and then separated.

Thus, the hose H passes through the rear of the supporter S while the distance of the slider 230 is set.

 Also, the ink is supplied through the ink hose 260 to be filled with the ink nozzle 250 through the through-hole 235 of the slider 230. At this time, since the ball 257 closes the lower end of the pipe 251, the ink is prevented from being discharged.

In this state, after the cut portion of the hose H coincides with the gap 223, the hydraulic cylinder 210 is driven to lower the rod 213, so that the compression block 220 descends, H). 6, the hose H is accommodated in the lower groove 233, and the hose H accommodated in the lower groove 233 is also V-shaped since the both side sliders 230 are V-shaped. Of course, the supporter S supports both sides of the hose H from the front. Thus, the hose H is curved in U-shape. At this time, as the ball 257 mounted on the ink nozzle 250 is pressed, the compression spring 255 is contracted and the ink is discharged through the lower end of the pipe 251, so that the marking M is displayed on the hose H .

In this state, the rotating cutter 300 is rotated to cut the hose H, and then rotate again in the reverse direction.

After the cutting, the compression block 220 is lifted by the operation of the fluid cylinder 210, so that the cutting operation is completed.

According to the present invention, since the marking (M) is displayed at the set point at the time of cutting the hose (H), the operator can solve the inconvenience of marking the marking (M) separately on the cut hose . Therefore, there is an advantage that the productivity can be improved.
