Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of edge cutting and material collecting, particularly to an edge cutting and material collecting device for PTFE high-temperature adhesive tape coating equipment. BACKGROUND

[0002] PTFE (polytetrafluoroethylene) high-temperature adhesive tape is a functional adhesive tape made of PTFE film or PTFE-coated glass fiber cloth as the base material, with high-temperature-resistant and corrosion-resistant properties. Coating equipment is an automatic production line device for uniformly coating liquid or semi-solid materials such as adhesives and coatings on the surface of the base material (such as PTFE film and glass fiber cloth), which is the core link of PTFE high-temperature adhesive tape production. Before the semi-finished adhesive tape is wound after coating and drying, the irregular part (such as coating overflow and edge burr) needs to be cut off, and the qualified adhesive tape needs to be separated from the waste material to ensure that the finished product edge is neat and the width is consistent, and the original release paper is saved to facilitate the user to peel off the adhesive tape, improving the work efficiency.

[0003] In the prior art, the raw material is usually transported by using unwinding rollers and winding rollers, and the edge is cut by using an edge cutting tool during the transportation process, and the waste material cut off is also wound. However, during the waste material winding process, the diameter of the waste material winding roller gradually increases, and under the condition that the rotation speed is constant, the winding speed will continuously increase, resulting in that the winding speed and the unwinding speed are inconsistent, the edge of the adhesive tape and the release paper are cut off at the same time, and the speed of peeling off the adhesive tape during use is affected.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and the "embodiments" referred to herein can include specific features, structures or characteristics in at least one implementation of the present application.

[0023] EMBODIMENT

[0024] Referring to Figures 1-4This embodiment provides a trimming and take-up device for a PTFE high-temperature tape coating equipment. Specifically, it includes a frame 1, which is connected to a trimming assembly and a take-up assembly for winding up the waste material 5 cut off by the trimming assembly. The take-up assembly includes a take-up roller 301 and a guide 302 that can move along the axial direction of the take-up roller 301. The guide 302 is connected to a controller 304 for adjusting the rotational speed of the take-up roller 301. The guide 302 is connected to a reset member 303. When the take-up speed is greater than the unloading speed, the guide 302 is pulled closer to the take-up roller 301 by the traction force of the waste material 5, causing the controller 304 to reduce the rotational speed of the take-up roller 301. When the take-up speed is less than the unloading speed, the guide 302 is pulled away from the take-up roller 301 by the tension of the reset member 303, causing the controller 304 to increase the rotational speed of the take-up roller 301.

[0025] The receiving assembly includes a mounting base 305, to which a drive rod 306 is rotatably connected. A controller 304 can move back and forth along the drive rod 306, and a guide 302 is rotatably connected to the top of the controller 304. A motor 307 is connected to the mounting base 305. The receiving roller 301, the drive rod 306, and the output shaft end of the motor 307 are connected via a belt 308. The rotation of the output shaft of the motor 307 drives the receiving roller 301 and the drive rod 306 to rotate synchronously.

[0026] Raw material 4 is conveyed via an unwinding device and a winding device. A positioning roller 201, located between the unwinding and winding devices, guides raw material 4 to the vicinity of the trimming assembly for trimming. Waste material 5 generated after trimming is collected by the take-up assemblies on both sides of the frame 1. Raw material 4 is a thin, low-hardness material that can be kneaded and tightened to pass through the guide 302 and wind onto the take-up roller 301. The take-up roller 301, drive rod 306, and motor 307 all pass through the mounting base 305 and are connected to the pulley via a belt 308.

[0027] The trimming assembly includes a positioning roller 201 and a crossbar 202 located above the positioning roller 201. The crossbar 202 has a groove 203, and at least two cutters 204 are slidably connected in the groove 203. The crossbar 202 is slidably connected to the frame 1. One end of the crossbar 202 is connected to a rotating component 205, and the rotating component 205 is threadedly connected to a fixing rod 206. The fixing rod 206 is fixedly connected to the frame 1.

[0028] In use, adjust the distance between the two cutters 204 and fix the cutters 204 with bolts. Finally, adjust the horizontal position of the crossbar 202 by rotating the component 205, leaving a suitable width on both sides of the raw material 4. The end of the crossbar 202 is provided with an annular groove, and the end of the rotating component 205 is a disc. The disc is in contact with the annular groove. When the disc moves along the fixed rod 206, it drives the crossbar 202 to move as a whole.

[0029] The mounting base 305 is fixedly provided with a guide rail 309, and the controller 304 is provided with a roller 310 capable of moving along the guide rail 309. The mounting base 305 is rotationally connected with a slide rod 311, and the guide 302 is slidably connected with the slide rod 311. The reset member 303 is a spring, one end of the spring is fixedly connected with a thimble 312, the other end of the spring is fixedly connected with the controller 304, and the thimble 312 is slidably connected with the guide 302.

[0030] The slide rod 311 is prismatic, and the guide 302 can rotate around the slide rod 311 as an axis. When the guide 302 rotates, the slide rod 311 rotates simultaneously. A sensor is arranged between the guide 302 and the controller 304, the sensor identifies the rotation angle of the guide 302, transmits a signal to the controller 304, controls the rotation speed of the motor 307, and realizes the adjustment of the winding speed. The specific connection relationship and working principle between the controller 304, the sensor and the guide 302 are common means in the prior art, and will not be described herein.

[0031] Importantly, although only several embodiments are described in detail herein, it should be readily understood that many modifications are possible in the substance of the described subject matter without materially departing from the novel teachings and advantages described herein such as variations in sizes, structures, shapes, and proportions of the various elements, values of the temperature, pressure, mounting arrangements, use of materials, colors, orientations, etc.; for example, the elements shown as integrally formed can be constructed of a number of separate elements or implemented as modules, the position of elements can be inverted or otherwise changed; therefore, all such modifications are intended to be included within the scope of the present application without materially departing from the novel teachings and advantages described herein.
