Description

Sealing tail mechanism capable of adapting to multiple winding diameter specifications

Technical field

The invention relates to the technical field of production and processing equipment for rolled materials, in particular to a sealing tail mechanism which can adapt to a multi-roll diameter specification.

Background technique

The existing reel will be sealed with glue at the end after winding to maintain the stability of the reel. The sealing method using glue bonding has the following three disadvantages: First, the roll will be used before use. During the tearing process, the outer ring of the reel which is bonded to the tail end is destroyed, so that a part of the tail end cannot be used normally; secondly, due to the certain permeability of the glue, in some cases, the inner layer of paper is often adhered. The user needs to tear off the multi-layer to use, which not only wastes materials, but also is inconvenient to operate. Thirdly, a large amount of glue is used in the tail end sealing of the existing reel, which not only requires additional material cost, but also glue is one. A kind of chemical synthetic material has certain harmful components and has certain volatility. It will have a negative impact on the health of workers or users during the production process or during use, and the use of a large amount of glue is not conducive to environmental protection.

Based on the above reasons, the applicant filed an invention patent application entitled "A Method and Reel for a Reel-free Environmental Sealing of a Reel" on 2015.11.12, the publication number is CN 105293196A, and the publication date is 2016.02.03. Specifically, the end of the reel is press-fitted by mechanical pressing, and the process does not require glue. However, the Applicant only discloses the method of its processing in this patent, and does not disclose the specific device structure for implementing the method.

However, the above-mentioned patent documents only disclose the mode of operation thereof, and do not disclose the specific device structure thereof; while the patent applications published as CN101674993A and CN104755400A disclose mechanically forming the folded portions, they are inefficient and cannot be used at one time. The end of the roll forms a seal. In addition, in the subsequent implementation process, the applicant found that the prior art still has the following deficiencies: when the reel of different reel diameters is sealed, the opening and closing range of the die must be adapted to the winding diameter, if the die is used. The opening and closing range is too small, it is difficult to press the multi-roll paper, so that the tail of the reel is easy to spread; if the opening and closing of the die is too large, it is necessary to press with a higher pressure during the pressing. Otherwise, it is difficult to press the tail portion tightly. If the opening and closing amplitude of the die on the same device is the same, it is necessary to configure different devices for the reels of different roll diameters, so that the initial cost of the manufacturer is huge, so it is necessary to design a machine that can adapt to a variety of different winding diameters. Sealing mechanism.

Referring to FIG. 2 and FIG. 3, wherein the sealing clip 2 includes two clamping arms 21 that are hinged to each other, and two connecting rods 22 respectively hinged to the rear ends of the two clamping arms 21, and the two clamping arms 21 are fixed to the frame by The pin shafts 23 on the 1 are hinged to each other, the two links 22 are hinged to each other, and the lifting slider 6 is also hinged at the hinge point of the two links 22, and the lifting slider 6 is slidably connected via the guide rails 7 provided on the frame 1. .

In this embodiment, the telescopic drive unit 3 is a cylinder or a hydraulic cylinder, and the two ends of the telescopic drive unit 3 are respectively connected through the fish eye joint arm 21 and the horizontal slider 4, specifically, the end of the telescopic rod of the telescopic drive unit 3 a hinge point between the connecting rod 22 and the caliper arm 21 in the tail clamp 2, the rear end of the cylinder of the telescopic drive unit 3 is hinged to the horizontal slider 4, and the horizontal slider 4 is slidably coupled to the frame along the telescopic direction of the telescopic drive unit 3. 1 is also provided with an adjustment mechanism for driving the horizontal slider 4 to slide. In the present embodiment, the adjusting mechanism 5 includes a screw 51 and a screw holder 52. The threads on both ends of the screw 51 are opposite, one end of which is screwed to the horizontal slider 4, and the other end of which is screwed with a screw holder 52, and the screw holder 52 is 52. Fixed connection to rack 1. Referring to Figures 4 and 5, wherein the horizontal slider 4 and the screw holder 52 are each provided with an adjustment groove 53 passing through the threaded hole thereof, and the threaded connection of the horizontal slider 4 is also vertically aligned. The adjusting bolt 54 of the groove 53 tightens the threaded hole of the horizontal slider 4 and the screw holder 52 with the adjusting bolt 54 by tightening the adjusting bolt 54.

Referring to FIG. 6 and FIG. 7 , the heads of the caliper arms 21 in this embodiment are each provided with a clamp mounting seat 25 and a clamping die 24 , and the clamping die mounting seat 25 and the clamping die 24 are connected by a connecting bolt 26 . Connected, and the die mount 25 is screwed on its outer side with a plurality of adjusting bolts 27 arranged along the width direction of the die mount 25 and pressed against the clamp 24 through the die mount 25 To adjust the parallelism between the two jaws 24. Specifically, when the two clamping dies 24 are closed, if a partial gap occurs between the two clamping dies 24, the adjusting bolts 27 at the corresponding slit positions are rotated, thereby adjusting the parallelism of the two to eliminate the gap between the two. In the present embodiment, the jaws 241 of the jaws 24 protrude from the inner side thereof, while the two jaws 24 are formed with interfitting serrations 242 on their jaws 241.

The two caliper arms 21 of the sealing clip 2 are opened and closed by the telescopic driving unit 3, and since the two caliper arms 21 and the two connecting rods 22 are hinged to each other, one of the caliper arms 21 is swayed by the telescopic driving unit 3 At the same time, the other caliper arm 21 is also driven to perform reverse swing, so that the two caliper arms 21 are synchronously opened and closed, so that the reel is evenly stressed when being clamped, and the reel is prevented from being damaged during sealing. When the first jaw 21a and the second jaw 21b are opened, the angle between the curved section of the control and the section of the reel 4 is controlled to be greater than 15 degrees and less than 50 degrees, and the angle can be adjusted by the pin. This facilitates the formation of a suitable force receiving portion of the gripper 214 and the reel to give the reel a sufficient clamping force to enable it to be tightly coupled without damaging the reel by excessive clamping force.
