Description

Technical Field

[0001] This utility model relates to the field of film production technology, specifically an automatic film counting device for intermittent winding and transmission. Background Technology

[0002] In modern industrial production, film winding and counting are crucial steps in many production processes. Film, as a widely used material, plays an indispensable role in electronics, optics, packaging, and many other fields. Whether it's insulating film in electronic devices, protective film in optical lenses, or sealing film in the packaging industry, the winding quality and quantity control during the production process directly affect the final product quality and production costs.

[0003] Traditional film winding equipment typically employs a simple mechanical structure, using a motor-driven unloading and take-up reels for film transport and winding. However, in actual production, this traditional equipment has several shortcomings. To ensure uniform and tight film winding, the unloading and take-up reels generally need to rotate synchronously. Initially, synchronous rotation is feasible, but as more film is wound onto the take-up reel, its diameter increases. At the same rotation speed, the take-up reel winds up more film, while the unloading reel's release speed cannot keep up, leading to a continuous increase in film tension. When the tension exceeds the film's tolerance limit, it is prone to stretching deformation or even breakage, severely impacting film quality and production continuity. Furthermore, traditional equipment also has limitations in film counting. Manual counting or simple mechanical counting devices are commonly used, resulting in low counting accuracy and susceptibility to human error and mechanical wear, leading to significant counting errors. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic film counting device for intermittent winding and transmission, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic film counting device for intermittent winding and transport includes a frame, a feeding tray, a receiving tray, and a counter. The feeding tray and the receiving tray are disposed at both ends of the frame via a drive assembly. When the drive assembly is running, the feeding tray and the receiving tray will rotate synchronously. The counter is located between the feeding tray and the receiving tray and is disposed on the frame. The frame is equipped with a compensation component. One end of the film on the feeding tray is fixedly connected to the receiving tray after being guided and supported by the compensation component. The compensation component can adjust the tension of the film as needed. With the cooperation of the drive component and the compensation component, the take-up tray will maintain a constant tension when winding the film on the unwind tray, and during this process, the counter can count the number of films wound by the take-up tray in real time.

[0006] The automatic film counting device with intermittent winding transport as described above: The drive assembly includes a first rotating shaft and a second rotating shaft, which are horizontally rotatably mounted at both ends of the frame, respectively. The feeding tray is coaxially mounted on the first rotating shaft, and the receiving tray is coaxially mounted on the second rotating shaft.

[0007] The automatic film counting device with intermittent winding transport as described above: A geared motor is installed on the frame, and the output end of the geared motor is coaxially and fixedly connected to one end of the second rotating shaft.

[0008] The automatic film counting device with intermittent winding transport as described above: A first pulley is coaxially mounted on the first rotating shaft, and a second pulley is coaxially mounted on the second rotating shaft. The first pulley and the second pulley are connected by a toothed belt.

[0009] The automatic film counting device with intermittent winding transport as described above: The compensation assembly includes a tensioning wheel and two guide rollers, the two guide rollers being symmetrically rotated on the frame; A support is provided on the frame, and one end of the tensioning wheel is vertically slidably mounted on the support. The tensioning wheel is located between the two guide rollers.

[0010] The automatic film counting device with intermittent winding transport as described above: One end of the film on the feeding tray is fixed to the outer wall of the receiving tray by passing through two guide rollers and the tensioning wheel in sequence.

[0011] The automatic film counting device with intermittent winding transport as described above: The compensation assembly also includes a slide vertically mounted on the frame and a slide seat vertically slidably mounted on the slide. The other end of the tensioning wheel is fixedly connected to the slide block. A lead screw that is threadedly engaged with the slide block is vertically rotatably mounted on the slide block. A stepper motor is mounted on the slide block, and the output end of the stepper motor is coaxially and fixedly connected to one end of the lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting up a compensation component, the tension of the film can be effectively adjusted, avoiding excessive film tension caused by increased film winding on the take-up reel. With the synergistic effect of the drive component and the compensation component, the take-up reel can maintain a constant tension when winding the film, ensuring that the film will not loosen or break due to tension changes during transmission, thus guaranteeing the transmission quality and stability of the film. At the same time, the real-time statistical function of the counter can accurately record the number of films wound by the take-up reel, improving the accuracy of film counting and increasing production efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-5 As an embodiment of this utility model, an automatic film counting device for intermittent winding and transmission includes a frame 1, a feeding tray 2, a receiving tray 3, and a counter 4. The feeding tray 2 and the receiving tray 3 are disposed at both ends of the frame 1 by a drive assembly. When the drive assembly is running, the feeding tray 2 and the receiving tray 3 will rotate synchronously. The counter 4 is located between the feeding tray 2 and the receiving tray 3 and is disposed on the frame 1. The frame 1 is equipped with a compensation component. One end of the film on the feeding tray 2 is fixedly connected to the receiving tray 3 after being guided and supported by the compensation component. The compensation component can adjust the tension of the film as needed. With the cooperation of the drive component and the compensation component, the take-up tray 3 will maintain a constant tension when winding the film on the unloading tray 2, and during this process, the counter 4 can count the number of films wound by the take-up tray 3 in real time.

[0021] In this embodiment, one end of the film to be wound on the unloading tray 2 is guided and supported by the compensation component and then fixedly connected to the take-up tray 3. When the drive component starts running, the unloading tray 2 and the take-up tray 3 rotate synchronously, and the film begins to be released from the unloading tray 2. After being guided and supported by the compensation component, it is wound up by the take-up tray 3. (During the film transport process, the compensation component adjusts in real time according to the tension of the film. When the film tension is low, the compensation component adjusts its own position or the tension adjustment device to make the film tension tight. When the film tension is too high, the compensation component makes the opposite adjustment to maintain the film tension within a suitable range.) As the take-up tray 3 winds up the film, the counter 4 starts working. The counter 4 monitors the film transmission in real time through built-in sensors or counting devices, accurately counts the number of films wound up by the take-up tray 3, and displays the counting results on the display screen of the counter 4 in real time for operators to check at any time. Throughout the winding process, as the amount of film wound on the take-up tray 3 gradually increases, its moment of inertia will also gradually increase, tending to accelerate the winding speed. Through the cooperation of the compensation component and the drive component, a constant tension is maintained on the film at all times, ensuring that the film will not slack, stretch, deform or break during the transmission and winding process, thus guaranteeing the winding quality of the film. During the film winding process, when the preset interruption conditions are met (such as the film length reaching a certain value, the count reaching a certain number, etc.), the drive component pauses operation, and the film winding temporarily stops. At this time, the operator can perform operations such as inspection, adjustment, or replacement of the film. After the operation is completed, the drive component restarts and continues to wind and count the film. This cycle continues until the entire winding task is completed.

[0022] As a further embodiment of this utility model, the drive assembly includes a first rotating shaft 5 and a second rotating shaft 6, which are respectively horizontally rotatably disposed at both ends of the frame 1. The feeding tray 2 is coaxially mounted on the first rotating shaft 5, and the receiving tray 3 is coaxially mounted on the second rotating shaft 6; A geared motor 7 is installed on the frame 1, and the output end of the geared motor 7 is coaxially and fixedly connected to one end of the second rotating shaft 6. A first pulley 8 is coaxially mounted on the first rotating shaft 5, and a second pulley 9 is coaxially mounted on the second rotating shaft 6. The first pulley 8 and the second pulley 9 are connected by a toothed belt 10.

[0023] In this embodiment, when the geared motor 7 starts, its output end drives the second rotating shaft 6 to rotate. Since the second rotating shaft 6 is coaxially and fixedly connected to the take-up tray 3, the take-up tray 3 also starts to rotate and begins to wind up the film. When the second rotating shaft 6 rotates, the second pulley 9 rotates accordingly. Since the first pulley 8 and the second pulley 9 are connected by a toothed belt 10, the rotation of the second pulley 9 drives the first pulley 8 to rotate through the toothed belt 10. The first pulley 8 is coaxially and fixedly connected to the first rotating shaft 5, thereby driving the first rotating shaft 5 to rotate, which in turn causes the feeding disc 2 to rotate and begin to release the film. Driven by the geared motor 7, the feeding tray 2 and the take-up tray 3 rotate synchronously through the transmission of the second rotating shaft 6, the second pulley 9, the toothed belt 10, the first pulley 8 and the first rotating shaft 5. The film is released from the feeding tray 2, guided and supported by the compensation component, and then wound up by the take-up tray 3.

[0024] As a further embodiment of this utility model, the compensation component includes a tensioning wheel 11 and two guide rollers 12, the two guide rollers 12 being symmetrically rotated on the frame 1; A bracket 13 is provided on the frame 1, and one end of the tensioning wheel 11 is vertically slidably mounted on the bracket 13. The tensioning wheel 11 is located between the two guide rollers 12. One end of the film on the feeding tray 2 is fixed to the outer wall of the receiving tray 3 by passing through two guide rollers 12 and the tensioning wheel 11 in sequence; The compensation assembly also includes a slide 14 vertically mounted on the frame 1 and a slide block 15 vertically slidably mounted on the slide 14; The other end of the tensioning wheel 11 is fixedly connected to the slide block 15. A lead screw 16 that is threadedly engaged with the slide block 15 is vertically rotatably mounted on the slide frame 14. A stepper motor 17 is mounted on the slide frame 14, and the output end of the stepper motor 17 is coaxially fixedly connected to one end of the lead screw 16.

[0025] In this embodiment, when the geared motor 7 starts, the feeding tray 2 and the take-up tray 3 begin to rotate synchronously. The film is released from the feeding tray 2, passes through two guide rollers 12 and tensioning roller 11 in sequence, and is wound up by the take-up tray 3. During film transport, tension wheel 11 plays the role of tensioning the film. Since tension wheel 11 is vertically slidably mounted on bracket 13, when the film tension changes, tension wheel 11 can slide up and down on bracket 13 to adjust the film tension. Specifically, the stepper motor 17 controls the rotation of the lead screw 16 according to a preset program or the real-time monitored film tension signal. Since the lead screw 16 is threadedly engaged with the slide 15, the rotation of the lead screw 16 will cause the slide 15 to slide vertically on the slide frame 14. The sliding of the slide 15 will cause the tension wheel 11 to move vertically. When the film tension is low, the stepper motor 17 drives the lead screw 16 to rotate, causing the slide 15 to move upward, and the tension wheel 11 to move upward accordingly, increasing the film tension. When the film tension is too high, the stepper motor 17 drives the lead screw 16 to rotate in the opposite direction, causing the slide 15 to move downward, and the tension wheel 11 to move downward accordingly, reducing the film tension. Two guide rollers 12 are symmetrically arranged to guide the direction of the film, ensuring that the film maintains a stable direction during transmission and preventing the film from shifting or twisting. The rotation of the guide rollers 12 can reduce the friction between the film and the rollers, allowing the film to pass smoothly through the guide rollers 12.
