Description

Technical Field

[0001] The utility model relates to the technical field of PS film production, in particular to a PS film cutting and winding device. Background Art

[0002] The component of PS film is polystyrene, which is a colorless and transparent plastic similar to glass. It is mainly used to produce foam insulation materials, light-transmitting materials and other products. PS film needs to be cut and rolled after production.

[0003] For example, a Chinese patent publication numbered CN219906305U discloses a PS film cutting and winding device comprising a base plate, a first guide roller mounted on one side of the base plate's top, a support frame fixedly mounted on the other side of the base plate's top, and a take-up roller rotatably mounted on the upper end of the support frame. The device comprises a transmission assembly, PS film, and a static elimination assembly. The output end of a servo motor, through transmission between a driving pulley, a driven pulley, and a belt, rotates the take-up roller to wind the PS film. A copper return spring pushes a copper limit ring fixed to the upper end of a copper movable rod upward, causing the copper roller at the top of the copper movable rod to closely contact the surface of the PS film. The copper movable rod, the copper limit ring, the copper return spring, and the copper roller are all made of copper metal. Static electricity generated by friction during PS film winding is then transferred to the ground via a wire, thereby reducing static electricity generated by the PS film.

[0004] However, the PS film cutting and winding equipment still has some shortcomings in actual use. For example, it cannot effectively control the amount of wound PS film, and staff need to monitor the winding equipment, which wastes manpower and has certain limitations in use. At the same time, after the PS film is wound, there is a lack of synchronized cutting components, and manual cutting is required, which is relatively inconvenient. Utility Model Content

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: comprising a winding assembly 1 for winding PS film, a warning cutting assembly 2 is fixedly installed at the rear end of the winding assembly 1, and a guide limit assembly 3 is fixedly installed at the front of the warning cutting assembly 2;

[0024] The early warning cutting component 2 includes a mounting plate 201, a side of the mounting plate 201 is provided with a vertical slide groove, an L-shaped slide plate 202 is slidably installed in the vertical slide groove, a lifting plate 203 is fixedly installed at the bottom end of the vertical part of the L-shaped slide plate 202, a top block 204 is fixedly installed on the top surface of the lifting plate 203, a top plate 205 is fixedly installed on the top of the mounting plate 201, a switch button 206 is fixedly installed on the bottom surface of the top plate 205, the switch button 206 is located just above the top block 204, and the top surface of the top plate 205 is away from the mounting plate 201. A buzzer alarm 207 is fixedly installed on one edge of the top plate 205, a support plate 208 is fixedly installed on the front of the top plate 205, and a cutting knife 209 is fixedly installed on the front end of the bottom of the support plate 208. The cutting knife 209 will also just pass through the open slot 306 opened on the top surface of the top limiting clamping plate 304. The end of the cutting knife 209 that passes through contacts the top surface of the PS film. As the lifting plate 203 continues to rise, the guide limiting component 3 will drive the PS film to rise synchronously, and then the PS film can be cut, and the staff does not need to manually cut it after the winding is completed.

[0025] The guide and limiting assembly 3 includes a bracket 301, a side plate 302 is fixedly installed at the edges of both sides of the bottom surface of the bracket 301, a cylinder 303 is fixedly installed in the middle of the top surface of the bracket 301, and two limiting clamps 304 are arranged between the two side plates 302. One limiting clamp 304 is fixedly installed at the bottom between the two side plates 302, and the top surface of the other limiting clamp 304 is fixedly connected to the bottom end of the piston rod of the cylinder 303.

[0026] In this embodiment, the winding assembly 1 includes a base plate 101, and three vertical plates 102 are fixedly installed on one side of the top surface of the base plate 101. One side of the three vertical plates 102 are rotatably installed with a No. 1 guide roller 103, a No. 2 guide roller 104 and a winding roller 105. The No. 1 guide roller 103, the No. 2 guide roller 104 and the winding roller 105 are arranged in a staggered manner at different heights. The winding roller 105 is located directly below the lifting plate 203. The PS film produced at the front end will pass through the top of the No. 1 guide roller 103 and the bottom of the No. 2 guide roller 104 in turn, and then pass between the two sets of conveying rollers 305, and finally be wound on the winding roller 105. The winding roller 105 can be driven to rotate by a motor. The PS film can be wound on the reel mounted on the winding roller 105 by rotating the winding roller 105.

[0027] A through opening slot 306 is formed in the middle of the top surface of each of the two limiting clamps 304 . The cutting blade 209 corresponds to the opening slot 306 and is located directly above the opening slot 306 .

[0028] The mounting plate 201 is fixedly mounted on the top surface of the vertical plate 102 at the rear end, and the rear end of the bracket 301 is fixedly connected to the top surface of the lifting plate 203 .

[0029] Conveying rollers 305 are rotatably mounted on the front and rear ends of the opposite surfaces of the two limiting clamping plates 304 . The conveying rollers 305 can guide and convey the PS film while clamping and limiting the PS film.

[0030] When in use, the PS film produced at the front end will pass through the top of the No. 1 guide roller 103 and the bottom of the No. 2 guide roller 104 in sequence, and then pass between the two sets of conveying rollers 305, and finally be wound on the winding roller 105. The winding roller 105 is driven by the motor to rotate. The PS film can be wound on the reel set on the winding roller 105. As the winding roller 105 continues to rotate, more and more PS film will be wound on the winding roller 105, which will cause the radius of the rolled PS film roll to become larger and larger. As the PS film roll becomes larger and larger, its surface will contact the bottom surface of the lifting plate 203. As the thickness of the PS film roll continues to increase, the lifting plate 203 will be slowly lifted up. When the thickness of the PS film roll reaches a certain level, the lifting plate 203 will be lifted up slowly. After the degree of tension is reached, the lifting plate 203 rises and drives the top block 204 to contact the switch button 206. The top block 204 continues to move and presses the switch button 206. Pressing the switch button 206 will cause the buzzer alarm 207 to flash and alarm, thereby reminding the staff that the PS film has completed a certain amount of winding. At the same time as the top block 204 just contacts the switch button 206, the cutting knife 209 will just pass through the open slot 306 provided on the top surface of the top limiting splint 304. The end of the cutting knife 209 that passes through will contact the top surface of the PS film. As the lifting plate 203 continues to rise, the guide limiting assembly 3 will drive the PS film to rise synchronously, thereby cutting the PS film, thereby eliminating the need for the staff to manually cut it after the winding is completed.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
