Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive production, and particularly relates to a winding and cutting device for double-sided adhesive production. Background Technique

[0002] The double-sided adhesive is a roll-shaped adhesive tape made by using paper, cloth, or plastic film as the base material and uniformly coating an elastomeric pressure-sensitive adhesive or a resin-based pressure-sensitive adhesive on the above base material, and consists of three parts: a base material, an adhesive, and a release paper (film) or a siliconized paper.

[0003] In the later stage of double-sided adhesive production, it is necessary to perform fixed-length winding and cutting. For example, a fixed-distance cutting and winding device for double-sided adhesive production disclosed in the patent publication number CN216105133U includes a housing, a lead screw slide rail, a support rod A, a rotating rod, a double-sided adhesive roller, and a chute A. On both the upper and lower sides at one end of the outer wall of the housing, lead screw slide rails are fixedly installed. On the outer sides of the lead screw slide rails, support rods A are slidably arranged through sliders. On the opposite surfaces of the support rods A, rotating rods are rotatably arranged through bearings. A double-sided adhesive roller is arranged between the rotating rods. Chutes A are fixedly installed at both the upper and lower ends of the double-sided adhesive roller. The staff slides two baffles on both ends of the support rod B, clamps the winding reel in the middle, then the staff fixes the baffles to the winding reel and the support rod B respectively through bolts. After placing the support rod B between the chutes B, the staff controls the electric telescopic rod B to drive the chute B to extend, so that both ends of the support rod B slide into the chute B. Then the staff fixes the support rod B and the chute B through bolts.

[0004] Based on the above search and combined with the existing technology, it is found that in the prior art, similar to the above-disclosed winding and cutting device for double-sided adhesive production, after one roll of winding and cutting is completed, most of them need to manually change the roll, and at the same time, it is necessary to manually stick the free end of the double-sided adhesive tape to the newly replaced winding roller, which is rather troublesome. Therefore, a winding and cutting device for double-sided adhesive production is proposed to improve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment: Refer to Figures 1-4The coiling and cutting device for double-sided tape production shown in the figure includes a frame 1. At the upper end of one side of the frame 1, a first mounting frame 2 is installed. Inside the first mounting frame 2, a flipping seat 3 is rotatably installed. At the side end of the first mounting frame 2, a first driving motor 4 for driving the flipping seat 3 to rotate is installed. Inside the flipping seat 3, a first coiling roller 5 and a second coiling roller 6 are detachably and rotatably installed, and the first coiling roller 5 and the second coiling roller 6 are arranged in parallel. At the side end of the flipping seat 3, a second driving motor 7 for driving the first coiling roller 5 and the second coiling roller 6 to rotate is installed.

[0024] Through the cooperative setting of the first driving motor 4, the flipping seat 3, the first coiling roller 5 and the second coiling roller 6, after one coiling roller finishes coiling, the first driving motor 4 can be used to drive the flipping seat 3 to flip 180 degrees, so that the first coiling roller 5 and the second coiling roller 6 are swapped up and down. The coiling roller that has finished coiling rotates to the lower side, and the newly replaced coiling roller rotates to the upper side. The double-sided tape part between the first coiling roller 5 and the second coiling roller 6 is cut off, and the newly replaced coiling roller is used to continue coiling the double-sided tape, and the coiling roller that has finished coiling is replaced (at this time, the staff only needs to complete the replacement of the new coiling roller before the next coiling roller finishes coiling. This time is relatively sufficient and will not affect the coiling progress). This solution can achieve rapid roll change and coiling, and there is no need for manual rapid roll change, making the operation more convenient.

[0025] Among them, at the upper end of the other side of the frame 1, a second mounting frame 8 is installed, and a cutting mechanism is installed on the second mounting frame 8. Specifically, the cutting mechanism includes an electric push rod 9 and a cutting part 10. The cutting part 10 includes a tool holder 101 and a cutting knife 102. The electric push rod 9 is installed at the side end of the second mounting frame 8, and the output end of the electric push rod 9 facing the first mounting frame 2 is fixed to the tool holder 101. The cutting knife 102 is fixed on the tool holder 101, and the cutting knife 102 is located between the first coiling roller 5 and the second coiling roller 6.

[0026] After the flipping seat 3 flips 180 degrees, the electric push rod 9 is used to drive the cutting knife 102 to move towards the double-sided tape part between the first coiling roller 5 and the second coiling roller 6 to cut off the double-sided tape.

[0027] In order to assist the free end of the cut double-sided tape to adhere to the surface of the newly replaced coiling roller and the double-sided tape roll that has finished coiling, the cutting part 10 further includes a pressing block 103 and a first elastic connecting piece 104. Grooves 105 are provided at the side ends of the tool holder 101 close to the first coiling roller 5 and the second coiling roller 6. The pressing block 103 is fixed to the inner bottom end of the groove 105 through the first elastic connecting piece 104, and the pressing block 103 protrudes outside the groove 105.

[0028] Through the cooperation setting of the pressing block 103 and the first elastic connecting piece 104, after the cutting knife 102 cuts off the double-sided tape, the electric push rod 9 can continue to push the tool holder 101 towards the middle position between the first winding roller 5 and the second winding roller 6. During this process, the pressing block 103 cooperates with the first elastic connecting piece 104 to press the two free ends of the cut double-sided tape onto the surface of the newly replaced winding roller and the double-sided tape roll that has been completely wound respectively, realizing unmanned automatic cutting and bonding, and greatly improving the operation efficiency.

[0029] Wherein, a roller 106 is rotatably installed at the end of the pressing block 103 protruding outside the first groove 105. A second groove 107 adapted to the roller 106 is provided on the tool holder 101 for receiving the roller 106. The roller 106 is in rolling contact with the double-sided tape, with small friction, and can better protect the double-sided tape.

[0030] In order to reduce the probability of accidental injury of the cutting knife 102, the cutting part 10 further includes a protective plate 108 and a second elastic connecting piece 109. A third groove 1010 is provided at the end of the tool holder 101 where the cutting knife 102 is installed. The protective plate 108 is fixed to the inner bottom end of the third groove 1010 through the second elastic connecting piece 109. The third groove 1010 protrudes outside the third groove 1010 and protrudes from the vertical plane where the cutting end of the cutting knife 102 is located. In the non-cutting state, the protective plate 108 blocks the side end of the cutting knife 102 under the elastic force of the second elastic connecting piece 109, avoiding accidental injury caused by the cutting end of the cutting knife 102 protruding. And through the cooperation setting of the protective plate 108 and the second elastic connecting piece 109, it will not hinder the cutting of the double-sided tape by the cutting knife 102.

[0031] The above-mentioned first elastic connecting piece 104 and second elastic connecting piece 109 are preferably conventional compression springs.

[0032] The working principle of the present utility model: As Figure 2 shown, the second driving motor 7 is used to drive one of the winding rollers located on the upper side to rotate to wind the double-sided tape. After one winding roller has been completely wound, the first driving motor 4 can be used to drive the flipping seat 3 to flip 180 degrees, so that the first winding roller 5 and the second winding roller 6 are swapped up and down. As Figure 4It is shown that the winding roller after winding is rotated to the lower side, and the newly replaced winding roller is rotated to the upper side. The electric push rod 9 is used to drive the cutting knife 102 to move towards the double-sided tape part between the first winding roller 5 and the second winding roller 6 to cut the double-sided tape. After the cutting knife 102 cuts the double-sided tape, the electric push rod 9 continues to push the tool holder 101 towards the middle position between the first winding roller 5 and the second winding roller 6. During this process, the pressing block 103 and the first elastic connecting piece 104 can respectively press the two free ends of the cut double-sided tape on the surface of the newly replaced winding roller and the double-sided tape roll after winding. The newly replaced winding roller is used to continue winding the double-sided tape, and the winding roller after winding is replaced.
