Glass bead cutting equipment
Technical Field
The invention relates to glass bead cutting equipment.
Background
The glittering and translucent glass beads have good color, transparency and three-dimensional effect, so that when being embroidered on the fabric, the glittering and translucent glass beads can produce visual impact incomparable with other embroidery materials, and therefore, the glittering and translucent glass beads are more and more applied to clothes and artware. The demand of the bead embroidery for the bead is increased.
However, the existing glass beads are difficult to process and are formed by pressing once or more, pressing is difficult for beads with smaller sizes, and an embroidery bead needle hole and the beads are easy to be eccentric, so that the bead precision is low, and the requirement of bead embroidery cannot be met. And the processing cost of the pressed beads is high, and the processing efficiency is low.
The other is formed by cutting a glass column, which is cut to pass through a grinding wheel sheet. Because the grinding wheel is worn and cut, the waste of the grinding wheel and the glass column is easily caused. When each bead is cut, the glass column which is not less than the cutting grinding wheel and is long in thickness is wasted, and the loss caused by abrasion is quite large when the glass column is just one glass column. The smaller the diameter of the beads, the greater the waste will be. In addition, the abrasion of the grinding wheel is large in the cutting process, 125 grinding wheels are consumed by one machine one week according to statistics, each grinding wheel is 16 yuan, and each machine consumes 4 tons of water per hour. And is also a reason for the high cost of glass beads.

Detailed Description
Referring to fig. 1-8, the present embodiment includes at least one pair of clamping plates 1 capable of clamping and rubbing to drive a clamped glass column 7 to rotate, sharp-edged cutters 2 disposed at one end of the clamping plates 1 to cut the glass column 7 extending out of the clamping plates 1, and a frame 8 for fixing each component, wherein the cutters 2 and the axes of the rotating glass column 7 are in relative longitudinal and transverse feed motions, the cutting edges of the cutters 2 and the axes of the glass column 7 are in relative opposite feed motions to form a longitudinal feed motion, and the cutters 2 and the glass column 7 are in relative sliding motion along a straight line where the cutting edges are located to form a transverse feed motion to cut the glass column 7. The direction of rotation of the tangent point of the cutter 2 on the glass column 7 is the direction of transverse feed motion, so that the glass column 7 rolls on the cutting edge of the cutter 2, the cutting friction force is reduced, the flatness of the cutting edge of the glass column 7 is favorably improved, the cutter 7 is uniformly worn, the cutting precision of glass beads can be increased, and the service life of the cutter is prolonged. The glass column 7 may be a solid or hollow cylinder.
In order to simplify the mechanism, in the embodiment, the clamping plates 1 clamp one side of the glass column 7, and at least one clamping plate 1 is provided with a soft elastic layer 11, in the embodiment, both clamping plates 1 are provided with soft elastic layers 11, and the elastic layers 11 can be made of rubber. At least one side of the clamping plate 1 is provided with a rest 5 for positioning the glass column 7, in order to improve the positioning precision of the glass column, the rest 5 is arranged at two sides of the clamping plate 1, and a plurality of rest 5 can be arranged according to the length requirement of the glass column, wherein 4 rest are arranged in the attached drawing. One or more tube slots 51 matched with the corresponding glass columns 7 are arranged on the rest stand 5 in sequence, and the axial lead of the tube slot 51 is superposed with the axial lead of the glass column after the clamping plates 1 clamp the corresponding glass column 7, so that the two clamping plates 1 are ensured to be separated, and the glass column 7 is positioned in the tube slot 51. The linear speed of the two rubbing clamping plates 1 is the same, so that the glass column 7 can be positioned in the tube groove 51 to rotate in situ, and the cutting precision of the beads can be further improved. Specifically, racks are arranged on one corresponding side of each of the two rubbing clamping plates 1, a driving gear 6 is arranged between the two racks to drive the two rubbing clamping plates 1 to rub, and the linear speeds of the two rubbing clamping plates 1 are the same, and the directions of the two rubbing clamping plates 1 are opposite. But can of course also be realized by means of a toothed belt.
The bottom of the clamping plate 1 is provided with a trough 3 for receiving the cut beads, and the trough 3 can be provided with an inclined downward discharge hole 31 for facilitating the transfer of the beads. The clamping surfaces of the clamping plates 1 are obliquely arranged, form a certain angle with the horizontal plane, and are obliquely downward with one end matched with the cutter 2, so that the cut beads automatically slide in the trough 3.
In order to stably clamp the glass column 7 which is positioned in the pipe groove 51 of the rest stand 5 in the clamping process, the clamping plates 1 are provided with a clamping driving mechanism for driving the two clamping plates 1 to synchronously clamp, and the clamping driving mechanism can adopt mechanical structures such as air pressure, hydraulic pressure or a motor, a rack and the like.

The edge surface of one side of the cutting knife 2 facing the clamping plate 1 is vertical to the axial lead of the glass column 7, and the other edge surface forms an acute angle with the axial lead of the glass column 7. In the cutting process, due to the brittleness of the glass, the edge surface of the acute angle can extrude the glass column (namely the glass bead) on the surface of the blade surface of the cutting knife 2 as long as the blade edge cuts into one part of the glass column. And the cutter is not required to be completely cut into the glass column 7, so that the cutting time can be greatly saved.
