Description
Technical Field
[0001] The utility model relates to the technical field of sensor strap production, in particular to a film tightness adjustment device for sensor strap production. Background Art
[0002] In the field of sensor strap production, films are widely used. With the continuous development of sensor strap production technology, the requirements for controlling the tightness of films during transmission are becoming increasingly higher. In the sensor strap production process, the transmission stability of the film directly affects the quality and production efficiency of the product. Traditional film transmission devices often use fixed conveyor rollers, which cannot flexibly adjust the tightness according to the actual situation of the film, resulting in the film being prone to slack or over-tension during transmission, affecting product quality and production efficiency. Therefore, we have introduced a new film tightness adjustment device for sensor strap production. Summary of the invention
[0003] The main purpose of the utility model is to provide a film tightness adjustment device for producing sensor straps, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A film tightness adjustment device for producing sensor straps, comprising a workbench, the lower end of the workbench is fixedly connected to a base, the four corners of the lower end of the base are fixedly connected to support feet, the upper front end and the upper rear end of the workbench are jointly fixedly connected to a support plate, the upper front end and the upper rear end of the support plate are both provided with sliding grooves, the upper front plate wall and the upper rear plate wall of the support plate are jointly movably connected to a main device, the front middle part and the lower front end of the support plate are respectively fixedly connected to a No. 2 drive motor and a No. 1 drive motor, the output end of the No. 2 drive motor passes through the support plate and is fixedly connected to a No. 2 conveying roller, and the output end of the No. 1 drive motor passes through the support plate and is fixedly connected to a No. 1 conveying roller;
[0006] The main device includes a tensioning roller, the middle of the front end and the middle of the rear end of the tensioning roller are fixedly connected with a connecting shaft, the front ends and rear ends of the two connecting shafts are movably connected with adjustment components through bearings, and the tensioning roller is located directly above the No. 2 conveying roller.
[0007] Preferably, the adjustment assembly includes a slider, an upper end of which is fixedly connected to a buffer spring, and the slider is movably connected to the front end of the connecting shaft on the front side.
[0008] By adopting the above technical solution: the introduction of the slider and the buffer spring provides additional stability for the adjustment component, while the buffer spring can absorb the impact and vibration generated during the adjustment process, thereby improving the stability and durability of the device.
[0009] Preferably, the upper end of the buffer spring is fixedly connected to the upper groove wall of the slide groove.
[0010] By adopting the above technical solution: the fixation and stable operation of the buffer spring are ensured.
[0011] Preferably, the sliding block is slidably connected in a sliding groove on the front side.
[0012] By adopting the above technical solution: this design enables the slider to slide along the slide groove, thereby achieving precise adjustment of the position of the tensioning roller.
[0013] Preferably, the structure of the tensioning roller is the same as that of the second conveying roller and is symmetrically distributed up and down.
[0014] By adopting the above technical solution: this design enables the tension roller and the second conveying roller to work better together, ensuring that the film maintains appropriate tightness during the transmission process.
[0015] Preferably, the structure of the No. 1 conveying roller is the same as that of the No. 2 conveying roller.
[0016] By adopting the above technical solution, it is ensured that the No. 1 conveying roller and the No. 2 conveying roller have the same performance and effect when conveying the film, thereby improving the working efficiency and stability of the entire device.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] In the utility model, the setting of the adjustment component can realize flexible fine adjustment of the tension roller position. When the tension of the film fluctuates slightly during the production process, the buffer spring can respond in time and drive the slider to move in the slide slot, so that the tension roller can quickly adapt to the change and accurately adjust the tension of the film. This instant response capability effectively reduces the quality problems of the film caused by unstable tension, such as wrinkles caused by local looseness or the risk of breakage caused by local overtightening. At the same time, it also reduces the scrap rate caused by tension problems, improves the overall production efficiency and product qualification rate, and brings significant economic benefits to the enterprise.
[0019] In the utility model, a soft and gradual way is provided for adjusting the tensioning roller through a buffer spring. Compared with the traditional rigid adjustment method, it greatly reduces the mechanical damage that may be caused to the film during the adjustment process. When the tensioning force needs to be adjusted to a larger extent, the elastic buffering effect of the buffer spring can avoid the impact of the sudden and large movement of the tensioning roller on the film, thereby protecting the integrity and physical properties of the film. Moreover, this soft adjustment mechanism can also extend the service life of the equipment, reduce the wear and failure of components caused by frequent rigid adjustment, reduce the maintenance cost and downtime of the equipment, and ensure the continuity and stability of production.

[0028] See also Figure 1-4 , the utility model provides a technical solution:
[0029] A film tightness adjustment device for producing sensor straps, comprising a workbench 1, a base 2 is fixedly connected to the lower end of the workbench 1, and support feet 3 are fixedly connected to the four corners of the lower end of the base 2, and the front and rear ends of the upper end of the workbench 1 are fixedly connected to a support plate 4, and the upper front end and the upper rear end of the support plate 4 are provided with a slide groove 5, and the upper front plate wall and the upper rear plate wall of the support plate 4 are movably connected to a main device 9, and the middle and lower front ends of the support plate 4 are respectively fixedly connected to a No. 2 drive motor 8 and a No. 1 drive motor 6, and the output end of the No. 2 drive motor 8 passes through the support plate 4 and is fixedly connected to a No. 2 conveying roller 10, and the output end of the No. 1 drive motor 6 passes through the support plate 4 and is fixedly connected to a No. 1 conveying roller 7;
[0030] The structure of the first conveying roller 7 is the same as that of the second conveying roller 10 .
[0031] In this embodiment, the main device 9 includes a tensioning roller 92, and the middle part of the front end and the middle part of the rear end of the tensioning roller 92 are fixedly connected with a connecting shaft 91. The front ends and rear ends of the two connecting shafts 91 are movably connected with an adjustment component 93 through bearings. The tensioning roller 92 is located directly above the No. 2 conveying roller 10; the structure of the tensioning roller 92 is the same as that of the No. 2 conveying roller 10 and is symmetrically distributed up and down.
[0032] Through the above scheme, the tension roller 92 is located directly above the No. 2 conveying roller 10, and its function is to apply a certain tension force to the film being conveyed to ensure that the film maintains appropriate tightness during the conveying process. The two connecting shafts 91 are respectively connected to the front end and the rear end of the tension roller 92, and are movably connected to the adjustment component 93 through the bearing. The adjustment component 93 can slide in the slide groove 5 to adjust the distance between the tension roller 92 and the No. 2 conveying roller 10, and then adjust the tension of the film.
[0033] In this embodiment, the adjustment component 93 includes a slider 931, the upper end of which is fixedly connected to a buffer spring 932, and the slider 931 is movably connected to the front end of the connecting shaft 91 on the front side; the upper end of the buffer spring 932 is fixedly connected to the upper groove wall of the slide groove 5; the slider 931 is slidably connected in the slide groove 5 on the front side,
[0034] Through the above scheme, the connecting shaft 91 is a component connecting the tensioning roller 92 and the slider 931. When the slider 931 moves in the slide groove 5, it drives the connecting shaft 91 and the tensioning roller 92 to move up and down together. This movement enables the tensioning roller 92 to apply different pressures to the film, thereby adjusting the tightness of the film. The buffer spring 932 is located at the upper end of the slider 931, and its upper end is fixedly connected to the upper groove wall of the slide groove 5. The main function of the buffer spring 932 is to provide a restoring force so that the slider 931 and the connecting shaft 91 can return to the preset position when there is no external force. In addition, the buffer spring 932 can also provide damping during the movement of the slider 931 to reduce mechanical damage caused by rapid movement or impact. By sliding the slider 931 up and down in the slide groove 5, combined with the damping and restoring force of the buffer spring 932, the adjustment component 93 can realize precise adjustment of the position of the tensioning roller 92, thereby adapting to the film requirements of different tightness.
[0035] It should be noted that the utility model is a film tightness adjustment device for the production of sensor straps, which is mainly composed of a workbench 1, a base 2, a support foot 3, a support plate 4, a slide 5, a No. 1 drive motor 6, a No. 1 conveyor roller 7, a No. 2 drive motor 8, a No. 2 conveyor roller 10 and a main device 9. The No. 1 drive motor 6 and the No. 2 drive motor 8 respectively drive the No. 1 conveyor roller 7 and the No. 2 conveyor roller 10 to rotate, and transmit the film from one end of the device to the other end. The No. 1 conveyor roller 7 and the No. 2 conveyor roller 10 have the same structure to ensure that the film is evenly stressed during the transmission process. The tension roller in the main device 9 92 is located directly above the No. 2 conveyor roller 10 and forms a certain angle with the No. 2 conveyor roller 10. The function of the tensioning roller 92 is to apply a certain tensioning force to the film being transmitted. When the user or the automatic mechanism needs to adjust the tightness of the film, they can achieve this by controlling the position of the slider 931 in the slide groove 5. When the slider 931 moves downward, the pressure of the tensioning roller 92 on the film increases, and the tightness of the film becomes tighter; when the slider 931 moves upward, the pressure of the tensioning roller 92 on the film decreases, and the tightness of the film becomes loose. During the adjustment process, the buffer spring 932 provides the necessary damping and restoring force to ensure the smoothness and accuracy of the adjustment process.
