Description

Technical Field

[0001] The invention relates to the technical field of rewinding machines, and in particular to an automatic clamping mechanism for a material strip of a rewinding machine without bonding. Background Art

[0002] In the existing rewinding tape processing process, bonding the rewinding tape to a roller or other substrate is an important step. The traditional bonding method often uses glue or other adhesives. This method is not only inefficient, but also has unstable bonding effects and is prone to falling off or uneven bonding. In addition, the use of adhesives may also cause environmental pollution, which is not conducive to environmental protection and sustainable development. In order to solve the above problems, we propose a rewinding machine tape bonding-free automatic clamping mechanism. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a bonding-free automatic clamping mechanism for a rewinding machine material strip, which solves the problems raised by the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rewinding machine material strip bonding-free automatic clamping mechanism, comprising:

[0005] The first lifting module;

[0006] A second lifting module is installed at the driving end of the first lifting module;

[0007] A base mounted on the driving end of the second lifting module;

[0008] A heating plate installed at the bottom of the base;

[0009] A roller shaft, located at the side of the heating plate, and capable of cooperating with the second lifting module to lift the heating plate;

[0010] A film cutting device, installed on the side of the second lifting module, for cutting the rewinding tape;

[0011] A rewinding shaft, located directly below the rolling shaft;

[0012] The roller is sleeved on the outside of the rewinding shaft.

[0013] Furthermore, the second lifting module includes:

[0014] A seat plate, connected and fixed to the driving end of the first lifting module;

[0015] A lifting drive cylinder is installed on the upper part of the seat plate;

[0016] The guide shaft is slidably arranged inside the seat plate, and the telescopic end of the lifting drive cylinder and the bottom end of the guide shaft are both connected and fixed to the base.

[0017] Furthermore, the film cutting device comprises:

[0018] A track frame, mounted on a side of the seat plate;

[0019] A linear motor is installed inside the track frame and can move back and forth along the track frame;

[0020] The cutter head is installed at the lower part of the linear motor.

[0021] Furthermore, the roller shaft is rotatably connected to the lower part of the second lifting module through a bracket, and the bracket is symmetrically installed on the lower part of the seat plate.

[0022] Furthermore, the second lifting module can simultaneously drive the base, the heating plate, the roller shaft, the bracket and the film cutting device to move downward synchronously until the roller shaft is pressed on the upper part of the roller and the heating area of ​​the heating plate is in contact with the roller.

[0023] Furthermore, the driving rewinding shaft can drive the drum to rotate, so as to achieve the rewinding of the rewinding material tape outside the drum.

[0024] The present invention provides a rewinding machine material strip automatic clamping mechanism without bonding. Compared with the prior art, it has the following beneficial effects:

[0025] The rewinder's material strip adhesive-free automatic clamping mechanism achieves precise control of the heating plate, the roller shaft and the film cutting device by adopting a combined design of the first lifting module and the second lifting module. When the mechanism is working, it can automatically hot-melt the rewinding material strip and stick it to the outside of the roller without using any adhesive, thereby greatly improving the sticking efficiency and bonding quality.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-4 The present invention provides a technical solution: a rewinding machine material strip adhesive-free automatic clamping mechanism, mainly composed of a first lifting module 1, a second lifting module 2, a base 3, a heating plate 4, a roller shaft 5, a film cutting device 6, a rewinding shaft 7 and a roller 8, wherein the first lifting module 1 and the second lifting module 2 have the same structure, the second lifting module 2 is installed at the driving end of the first lifting module 1, the base 3 is installed at the driving end of the second lifting module 2, the heating plate 4 is installed at the lower part of the base 3, the roller shaft 5 is located at the side of the heating plate 4, and does not affect the second lifting module 2 driving the heating plate 4 to lift and lower, the film cutting device 6 is installed at the side of the second lifting module 2, and can cut the rewinding material strip, the rewinding shaft 7 is located directly below the roller shaft 5, and the roller 8 is sleeved on the outside of the rewinding shaft 7;

[0033] The second lifting module 2 is composed of a base plate 21, a lifting drive cylinder 22 and a guide shaft 23. The base plate 21 is connected and fixed to the driving end of the first lifting module 1. The lifting drive cylinder 22 is installed on the upper part of the base plate 21. The guide shaft 23 is slidably arranged inside the base plate 21. The telescopic end of the lifting drive cylinder 22 and the bottom end of the guide shaft 23 are both connected and fixed to the base 3.

[0034] The film cutting device 6 consists of a track frame 61, a linear motor 62 and a cutter head 63, wherein the track frame 61 is installed on the side of the base plate 21, the linear motor 62 is installed inside the track frame 61, the linear motor 62 can reciprocate along the track frame 61, and the cutter head 63 is installed at the bottom of the linear motor 62.

[0035] The roller shaft 5 is rotatably connected to the lower part of the second lifting module 2 through the bracket 51. The bracket 51 is symmetrically installed at the lower part of the seat plate 21. The second lifting module 2 can simultaneously drive the base 3, the heating plate 4, the roller shaft 5, the bracket 51, and the film cutting device 6 to move downward synchronously until the roller shaft 5 is pressed on the upper part of the roller 8, and the heating area of ​​the heating plate 4 is in contact with the roller 8.

[0036] When the mechanism is working, the roller 8 is sleeved on the outside of the rewinding shaft 7, and the rewinding shaft 7 can drive the roller 8 to rotate (the driving structure is not shown in the figure), and the rewinding tape that needs to be melted on the surface of the roller 8 will be wound on the outside of the roller 8 under the action of the rewinding shaft 7 driving the roller 8 to rotate. In this process, the first lifting module 1 will drive the second lifting module 2, the base 3, the heating plate 4, the roller shaft 5, and the film cutting device 6 to move downward synchronously. After moving downward, the roller shaft 5 will fit on the upper part of the roller 8, thereby generating a squeezing force on the rewinding tape, and ... second lifting module 1 will drive the second lifting module 2, the base 3, the heating plate 4, the roller shaft 5, and the film cutting device 6 to move downward synchronously. The lifting drive cylinder 22 of the second lifting module 2 will push the base 3 and the heating plate 4 downward until the heating area of ​​the heating plate 4 fits with the roller 8, so that the rewinding tape is rolled up on the outside of the roller 8. After the rewinding tape contacts the heating area of ​​the heating plate 4, it will be heat-melted. The heat-melted rewinding tape becomes sticky and adheres to the outside of the roller 8, and is squeezed by the roller shaft 5, making the adhesion more firm. After the rewinding tape is rolled up on the roller 8 for one circle, the linear motor 62 drives the cutter head 63 to move horizontally to cut the rewinding tape.
