When cutting papers of different sizes, the adjustment of the cutting knife needs to be manually adjusted, the adjustment method is not convenient, and the adjustment accuracy is not high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rewinding device for silicon oil paper processing, which is convenient for adjusting the cutting size when shearing silicon oil paper, aiming at the above existing technical problems.

[0005] In view of this, the utility model provides a rewinding device for silicon oil paper processing, which includes a bracket and an unwinding assembly, a positioning assembly, and a rewinding assembly on the bracket, and further includes: a first mounting frame, and the two first mounting frames are symmetrically arranged on the bracket; a paper cutting assembly, the paper cutting assembly is movably arranged on the top of the first mounting frame along the width direction of the silicon oil paper; a first roller, the first roller is rotatably arranged on the first mounting frame corresponding to the lower part of the paper cutting assembly; wherein, the paper cutting assembly abuts against the first roller downward to cut the silicon oil paper on the first roller.

[0006] In this technical solution, when the silicon oil paper passes above the first roller, the paper cutting assembly cuts the silicon oil paper. The paper cutting device can move along the width direction of the silicon oil paper. Before cutting the silicon oil paper, the paper cutting assembly is convenient to adjust the position, corresponding to the size of the silicon oil paper to be sheared, so as to improve the accuracy during cutting.

[0007] In the above solution, further, the paper cutting assembly includes a first motor, which is arranged on one side of the first mounting bracket. The output end of the first motor passes through the first mounting bracket and is coaxially connected to a first screw rod. The first screw rod is rotatably arranged on the first mounting bracket. The first screw rod is threadedly connected to a first slider. The first slider is provided with a limiting rod passing through it. The limiting rod is fixedly arranged on the first mounting bracket. A cutting unit is arranged at the bottom of the first slider.

[0008] In this technical solution, when the first motor is started, the output end drives the first screw rod to rotate, so that the first slider threadedly connected to the first screw rod displaces on the limiting rod. The first slider drives the cutting unit to displace. With the cooperation of the first motor and the first screw rod, the displacement accuracy of the first slider on the limiting rod is improved.

[0009] In the above technical solution, further, the cutting unit includes a pneumatic telescopic cylinder, which is fixedly arranged at the bottom of the first slider. The output end of the pneumatic telescopic cylinder is fixedly provided with a paper cutting knife housing; a paper cutting knife head is arranged in the paper cutting knife housing, and the paper cutting knife head cuts the silicon oil paper below.

[0010] In this technical solution, when the pneumatic telescopic cylinder extends, it controls the paper cutting knife head to contact the first roller and cuts the silicon oil paper on the first roller. When the pneumatic telescopic cylinder retracts, it controls the paper cutting knife not to contact the first roller and does not cut the silicon oil paper on the first roller. When adjusting the displacement of the first slider, the pneumatic telescopic cylinder drives the paper cutting knife head to displace upward. When the adjustment of the displacement of the first slider is completed, the pneumatic telescopic cylinder drives the paper cutting knife head to displace downward. When adjusting the first slider, it avoids the friction and wear of the paper cutting knife head in the horizontal direction of the first roller, and improves the service life of the paper cutting knife head.

[0011] In the above technical solution, further, the paper cutting knife housing includes an upper paper cutting knife housing and a lower paper cutting knife housing. A buffer unit is connected between the upper paper cutting knife housing and the lower paper cutting knife housing. The buffer unit elastically connects the upper paper cutting knife housing and the lower paper cutting knife housing.

[0012] In the above technical solution, further, the buffer unit includes a second screw rod, which passes through the upper paper cutting knife housing and is threadedly connected to the top end of the lower paper cutting knife housing. The second screw rod is sleeved with a first spring, and the first spring is arranged between the upper paper cutting knife housing and the lower paper cutting knife housing.

[0013] In the present technical solution, when the pneumatic telescopic cylinder is extended, the paper cutter head and the first roller collide with each other. Since the output of the pneumatic telescopic cylinder may change, the paper cutter head rebounds the excess output to the buffer unit on the paper cutter housing, and the first spring in the buffer unit is deformed to absorb the excess output, thereby avoiding hard collision of the paper cutter head due to the different output of the pneumatic telescopic cylinder. The paper cutter head and the first roller achieve a soft collision effect, thereby protecting the paper cutter head and increasing its service life.

[0014] In the above technical solution, further, it also includes a fixing component, which includes a second mounting frame, the second mounting frame is symmetrically arranged on the bracket, the second mounting frame is rotatably provided with a second roller, and a paper pressing component is arranged above the second mounting frame, and the paper pressing component presses the silicone oil paper on the second roller downward to press against the surface of the second roller.

[0015] In the above technical solution, further, the paper pressing assembly includes a third roller, the third roller is rotatably set on the second slider, the second slider is penetrated by a third screw, the third screw is threadedly connected to the top of the second mounting frame, and the third screw is sleeved with a second spring.

[0016] In this technical solution, the deformation of the second spring is controlled by rotating the second screw. The elastic force of the second spring causes the second slider to move downward, driving the third roller to clamp the silicone oil paper on the second roller, so that the silicone oil paper sticks to the surface of the second roller during transportation and is not easy to fall off.

[0017] The beneficial effects of the utility model are:

[0018] 1. By setting a first slider, the first slider drives the cutting unit to move, and the displacement accuracy of the first slider on the limiting rod is improved under the cooperation of the first motor and the first screw;

[0019] 2. By setting a pneumatic telescopic cylinder, when adjusting the displacement of the first slider, the pneumatic telescopic cylinder drives the paper cutter head to move upward, and when the displacement of the first slider is adjusted, the pneumatic telescopic cylinder drives the paper cutter head to move downward, so that when adjusting the first slider, friction and loss of the paper cutter in the lateral direction of the first roller are avoided, thereby improving the service life of the paper cutter head;

[0020] 3. By setting up a buffer unit, the different outputs of the pneumatic telescopic cylinder can be avoided to prevent the paper cutter head from hard contact and collision. The paper cutter head and the first roller achieve a soft contact effect, which protects the paper cutter head and increases its service life. BRIEF DESCRIPTION OF THE DRAWINGS
