Description

Technical Field

[0001] This invention relates to the field of film processing technology, and in particular to a film transmission mechanism based on thin-film capacitor winding and unwinding. Background Technology

[0002] A thin film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is defined as a two-dimensional material formed by the deposition of atoms, molecules, or ions onto a substrate surface. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in electronics, machinery, printing, and other industries. Thin film materials refer to thin metal or organic layers with a thickness ranging from a single atom to several millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of thin film technology. A slitting machine is a mechanical device that cuts wide strips of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. Slitting machines are mainly used for cutting non-woven fabrics, mica tape, paper, insulating materials, and various film materials, and are particularly suitable for cutting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, films, etc.).

[0003] In the process of slitting film, existing slitting machines are affected by the extensibility of the film material itself and other factors during the machine's operation and conveying process. This results in a speed difference between unwinding and rewinding of the film material. For example, during the process of transporting and pulling the film material along the unwinding roller to the film cutting roller, some static electricity is easily generated on the surface of the film material during the separation of the film material from the roll. During the frictional contact with the multi-roller group, a conveying delay is generated, which causes wrinkles or edge tilting differences in the film material when it passes through the film cutting roller, affecting the slitting quality of the film material and generating more slitting edge material.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a film transmission mechanism based on thin-film capacitor winding and unwinding to solve the problem that existing slitting machines, during the film slitting process, are affected by the film material's own extensibility and other factors during machine operation and conveying, resulting in a speed difference between unwinding and winding. For example, during the process of transporting and pulling the film material along the unwinding roller to the film cutting roller, static electricity is easily generated on the surface of the film material during the separation of the film material from the roll. During the frictional contact with the multi-roller group, a conveying delay is generated, causing wrinkles or edge tilting differences in the film material when passing through the film cutting roller, affecting the slitting quality of the film material and generating more slitting edge material.

[0007] The top of the support plate is provided with an edge material winding assembly near the film cutting drive assembly. The film winding assembly is provided on the side of the film cutting drive assembly away from the edge material winding assembly. The film winding assembly includes an inner plate and an outer plate that are mounted parallel to the support plate. An upper winding roller is rotatably connected to the top of the inner wall of the inner plate. A tension swing rod is installed on the side of the upper winding roller.

[0008] Preferably, the output end of the unwinding motor is connected to a driven wheel near the unwinding roller at the top of the drive wheel, an unwinding guide roller is mounted above the driven wheel, the driven wheel is connected to the rotating roller belt, a pressure roller is mounted on the top of the rotating roller, and a speed sensor is installed on the side of the rotating roller away from the unwinding roller.

[0009] Preferably, the tension sensor has a groove that passes through the support plate on the side away from the rotating roller, an adjusting wheel is slidably adjusted inside the groove, and an electric push rod that is driven and connected to the adjusting wheel is provided at the bottom of the groove.

[0010] Preferably, the film cutting transmission assembly includes a main speed roller, a servo motor fixedly connected to the outer wall of the support plate is driven and connected to one side of the main speed roller, a film cutting roller near the edge material winding assembly is provided at the top of the main speed roller, a film cutting motor fixedly connected to the outer wall of the support plate is driven and connected to one side of the film cutting roller, and multiple sets of electrostatic rollers are provided at the bottom of the film cutting roller and rotatably sleeved with the inner wall of the support plate.

[0011] Preferably, multiple sets of winding motors are fixedly installed on the side of the outer plate away from the support plate. The winding motors are connected by a belt drive to a drive shaft that passes through the support plate and the inner plate. A lower winding roller is installed side by side at the bottom of the upper winding roller. Both the upper and lower winding rollers are connected to the drive shaft.

[0012] Preferably, one side of the tension swing arm is driven by a swing arm motor that is fixedly connected to the outer wall of the support plate, and the bottom of the tension swing arm is provided with multiple sets of take-up guide rollers close to the main speed roller.

[0013] Preferably, the edge material winding assembly includes an edge material winding roller, the edge material winding roller is driven and connected to an edge material motor that is fixedly connected to the outer wall of the support plate, the bottom of the edge material winding roller is provided with multiple sets of edge material guide rollers, and the edge material guide roller is provided with a tension swing rod on its side.

[0014] The working method of the film transmission mechanism based on the winding and unwinding of thin-film capacitors includes the following steps:

[0015] Step 1: The unwinding motor synchronously drives the unwinding roller and the driven wheel via its output end. The main unwound film material is released from the unwinding roller and conveyed to the tension sensor along the unwinding guide roller, pressure roller, and rotating roller. The driven wheel drives the rotating roller via a belt to maintain a synchronous operating speed with the unwinding roller. The tension sensor constantly detects the tension of the film material transported between the main speed roller and the unwinding roller, passing through the film cutting roller, electrostatic roller, adjusting wheel, rotating roller, pressure roller, and unwinding guide roller. The adjusting wheel is driven by an electric push rod to shift axially along the chute, causing the unwinding roller and the main speed roller to maintain synchronous transmission operation.

[0016] Step 2: When the film material is transported along the adjusting rollers into multiple sets of electrostatic rollers, the electrostatic rollers are energized to treat the auxiliary static electricity on the film material. The film material is then transported along the electrostatic rollers into the film cutting rollers, where the film cutting rollers cut the edges of the film material and then pass through the main speed rollers to complete the pre-cutting transmission and conveying of the film material.

[0017] Step 3: The slit film material yields finished product and edge material. The finished product is separated along the main speed roller and transported to the upper and lower winding rollers respectively. During the winding process of the upper and lower winding rollers, the tension swing arm operates to perform targeted detection on the transport tension of the finished product and edge material between the main speed roller and the upper winding roller, the main speed roller and the lower winding roller, and the main speed roller and the corner winding roller.

[0018] Step 4: The oscillating motor drives the tension oscillating arm to deflect at an angle. The tension oscillating arm and the winding guide roller assist in adjusting the winding transmission speed of the film material as it is fed into the upper and lower winding rollers along the main speed roller. This causes the upper and lower winding rollers to maintain synchronous transmission with the main speed roller. The tension between the upper winding roller and the main speed roller, and between the lower winding roller and the main speed roller, respectively, regulates the tension of the film material winding and the tension of the waste material generated from film material slitting as it is wound to the edge material winding roller.

[0019] The beneficial effects of this invention are:

[0020] (1) The present invention uses the driven wheel to assist the rotating roller and the unwinding roller to rotate synchronously. With the unwinding guide roller and the pressure roller working together, the film material is promoted to be released at a uniform speed along the unwinding roller. The tension sensor is used to detect the tension of the film material during the transportation process from the unwinding roller along the rotating roller, the adjusting wheel and into the film cutting roller. The tension is adjusted in a targeted short distance to maintain the change of the transportation transmission speed during the unwinding process and to make the unwinding roller and the main speed roller keep synchronous transmission operation.

[0021] (2) The upper and lower rolls are kept in synchronous operation by the inner and outer plates. The winding transmission speed of the film material is adjusted by the tension swing rod and the winding guide roller. This makes the upper and lower rolls keep in synchronous operation with the main speed roller. The tension adjustment between the upper roll and the main speed roller and the lower roll and the main speed roller are respectively used to adjust the tension of the film material winding and the tension adjustment of the edge material generated by the film material slitting to the edge material winding roller. This makes the unwinding and winding transmission speed of the whole film material consistent during the slitting process. It can also make active tension adjustment to compensate for the difference caused by the film material's own extensibility and other factors. This constitutes a multi-stage synchronous transmission control of unwinding and winding of the film material slitting. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] This embodiment addresses the problem that existing slitting machines, during the film slitting process, suffer from a rate difference between unwinding and rewinding due to the film's own extensibility and interference from other factors during machine operation and conveying. For example, during the film's transport and traction along the unwinding roller to the film cutting roller, static electricity can easily adhere to the film's surface during the separation of the film roll and the film. This static electricity, combined with frictional contact with the multi-roller group, causes a conveying delay, resulting in wrinkles or edge tilting differences in the film as it passes through the film cutting roller. This affects the slitting quality of the film and generates more slitting edge material.

[0034] Please see Figure 1-3As shown, this embodiment is a film transmission mechanism based on thin-film capacitor winding and unwinding, including a support plate 1. A film unwinding assembly 3 is provided at the bottom of the support plate 1. The film unwinding assembly 3 includes an unwinding motor 301 fixedly connected to the outer wall of the support plate 1. The output end of the unwinding motor 301 passes through the support plate 1 and is connected to an unwinding roller 302. A belt-driven rotating roller 306 is mounted on the side of the unwinding roller 302. An unwinding tension adjusting assembly 4 is provided on the side of the rotating roller 306 away from the unwinding roller 302. The unwinding tension adjusting assembly 4 includes a tension sensor 404 near the rotating roller 306. A film cutting transmission assembly 5 is provided above the tension sensor 404. A driven wheel 303 near the unwinding roller 302 is connected to the top of the output end of the unwinding motor 301. An unwinding guide roller 304 is mounted above the driven wheel 303. The driven wheel 303 is belt-connected to the rotating roller 306. A pressure roller 305 is mounted on the top of the rotating roller 306, which assists the unwinding guide roller 304. The rotating roller 306 rotates synchronously with the unwinding roller 302. With the cooperation and linkage of the unwinding guide roller 304 and the pressure roller 305, the film material is promoted to be released at a uniform speed along the unwinding roller 302. A speed sensor 307 is installed on the side of the rotating roller 306 away from the unwinding roller 302. A groove 402 penetrating the support plate 1 is provided on the side of the tension sensor 404 away from the rotating roller 306. An adjusting wheel 403 is slidably adjusted inside the groove 402. An electric push rod 401 driven and connected to the adjusting wheel 403 is provided at the bottom of the groove 402. The film cutting transmission assembly 5 includes a main speed roller 501. A servo motor fixedly connected to the outer wall of the support plate 1 is driven and connected to one side of the main speed roller 501. A film cutting roller 502 near the edge material winding assembly 6 is provided at the top of the main speed roller 501. A film cutting motor fixedly connected to the outer wall of the support plate 1 is driven and connected to one side of the film cutting roller 502. Multiple sets of electrostatic rollers 503 are rotatably sleeved with the inner wall of the support plate 1 at the bottom of the film cutting roller 502.

[0035] The unwinding motor 301 synchronously drives the unwinding roller 302 and the driven wheel 303 via its output end. The unwinding roller 302 releases the main unwound film material and conveys it along the unwinding guide roller 304, pressure roller 305, and rotating roller 306 to the tension sensor 404. The driven wheel 303 drives the rotating roller 306 via a belt to maintain synchronous operation with the unwinding roller 302. With the assistance of the pressure roller 305, the film material is actively pulled, reducing the change in film material traction force caused by the gap difference between the main speed roller 501 and the unwinding roller 302. The tension sensor 404 constantly detects the film material passing between the main speed roller 501 and the unwinding roller 302, through the film cutting roller 502, the electrostatic roller 503, the adjusting wheel 403, the rotating roller 306, and the pressure roller. The tension of the film material transport between 305 and the unwinding guide roller 304 is adjusted by the electric push rod 401 driving the adjusting wheel 403 to offset axially along the slide 402, thus forming a targeted short-distance adjustment treatment for the film material before slitting. This maintains the change in the transport transmission speed of the film material during unwinding, causing the unwinding roller 302 and the main speed roller 501 to maintain synchronous transmission. When the film material is transported along the adjusting wheel 403 into the multiple sets of electrostatic rollers 503, the electrostatic rollers 503 are energized to treat the auxiliary static electricity on the film material. The film material is then transported along the electrostatic rollers 503 into the film cutting roller 502, where the film cutting roller 502 performs slitting processing on the edges of the film material and passes through the main speed roller 501, completing the transmission and transport of the film material before slitting.

[0036] Example 2:

[0037] This embodiment addresses the problem that existing slitting machines, during the film slitting process, suffer from a rate difference between unwinding and rewinding due to the film's own extensibility and interference from other factors during machine operation and conveying. For example, during the film's transport and traction along the unwinding roller 302 to the film cutting roller 502, static electricity can easily adhere to the film's surface during the separation of the film roll and the film. This static electricity, combined with frictional contact with the multi-roller group, causes a conveying delay, resulting in wrinkles or edge tilting differences in the film as it passes through the film cutting roller 502. This affects the slitting quality of the film and generates more slitting edge material.

[0038] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the film transmission mechanism based on thin-film capacitor winding and unwinding in this embodiment includes an edge material winding assembly 6 located on the top of the support plate 1 near the film cutting transmission assembly 5, and a film winding assembly 2 located on the side of the film cutting transmission assembly 5 away from the edge material winding assembly 6. The film winding assembly 2 includes an inner plate 201 and an outer plate 202 mounted parallel to the support plate 1. An upper winding roller 205 is rotatably connected to the top of the inner wall of the inner plate 201. The inner plate 201 and the outer plate 202 assist the upper winding roller 205 and the lower winding roller 206 in maintaining synchronous operation and transmission. A tension swing rod 209 is installed on the side of the upper winding roller 205, and tension sensors 404 are provided on the side of each tension swing rod 209. Multiple sets of winding motors 203 are fixedly installed on the side of the outer plate 202 away from the support plate 1. The winding motor 203 is connected by a belt drive to a drive shaft 204 that passes through the support plate 1 and the inner plate 201. The lower winding roller 206 is installed side by side at the bottom of the upper winding roller 205. Both the upper winding roller 205 and the lower winding roller 206 are connected to the drive shaft 204. The tension swing rod 209 is driven and connected to a swing rod motor 208 that is fixedly connected to the outer wall of the support plate 1. The tension swing rod 209 has multiple sets of take-up guide rollers 207 near the main speed roller 501 at its bottom. The edge material take-up assembly 6 includes an edge material take-up roller 601. The edge material take-up roller 601 is driven and connected to an edge material motor that is fixedly connected to the outer wall of the support plate 1 at its side. The edge material take-up roller 601 has multiple sets of edge material guide rollers 602 at its bottom, and the edge material guide roller 602 has a tension swing rod 209 on its side.

[0039] The slit film material yields finished product and edge material. The finished product is separated along the main speed roller 501 and transported to the upper winding roller 205 and lower winding roller 206 respectively. During the winding process of the upper winding roller 205 and lower winding roller 206, the tension swing rod 209 operates to perform targeted detection of the transport tension of the finished product and edge material between the main speed roller 501 and the upper winding roller 205, between the main speed roller 501 and the lower winding roller 206, and between the main speed roller 501 and the corner winding roller. The swing rod motor 208 drives the tension swing rod 209 to deflect at an angle, promoting the tension between the finished product and the upper winding roller 205 and lower winding roller 206. The tension adjustment, as well as the tension adjustment between the edge material and the edge material take-up roller 601, utilizes the tension swing arm 209 and the take-up guide roller 207 to assist in adjusting the take-up transmission speed of the film material conveyed along the main speed roller 501 into the upper take-up roller 205 and the lower take-up roller 206, so that the upper take-up roller 205 and the lower take-up roller 206 maintain synchronous transmission with the main speed roller 501. This constitutes the tension adjustment of the film material take-up between the upper take-up roller 205 and the main speed roller 501, and the tension adjustment of the waste material generated by the film material slitting to the edge material take-up roller 601.

[0040] Combining Embodiment 1 and Embodiment 2, it can both ensure that the unwinding and rewinding transmission speeds of the overall film material remain consistent during the slitting process, and can also utilize the differences caused by the film material's own extensibility and other factors to actively adjust and compensate for the tension, thus forming a multi-stage synchronous transmission control for the unwinding and rewinding of the film material during slitting.
