Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, specifically, it relates to a constant tension winding device for printed materials. Background Technology

[0002] In the printing production process, the winding stage has a significant impact on the quality of the finished product. Traditional winding equipment often suffers from poor tension control, leading to problems such as wrinkles and stretching deformation in printed materials, reducing the yield rate, and affecting the smoothness of subsequent processing (such as rewinding and cutting). The tension adjustment of existing winding equipment mostly relies on simple mechanical structures or manual adjustment, which has the drawbacks of slow response and low precision. Mechanical structures are prone to wear and tear after long-term operation, resulting in inaccurate tension detection and adjustment; manual adjustment is limited by operating experience and real-time requirements, making it difficult to adapt to tension fluctuations caused by factors such as changes in unwinding diameter and differences in material properties during the transmission of printed materials. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a constant tension winding device for printed materials that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a constant tension winding device for printed materials, including a frame, and further including: an unwinding wheel and a winding wheel rotatably connected to the frame, each unwinding wheel and winding wheel being provided with printed materials; a tension detection mechanism and a tension adjustment mechanism are fixedly connected to the frame; the tension detection mechanism includes a support shaft, the support shaft being fixedly connected to the frame, a detection rod being slidably connected through the support shaft, a bearing sleeve being rotatably connected to the support shaft, a detection spring being fixedly connected to the bearing sleeve, and a force detection cylinder being fixedly connected to the detection spring, the outer wall of the force detection cylinder corresponding to the printed materials.

[0005] Furthermore, the force detection cylinder is hollowed out at the center of the printed material, and one end of its detection rod corresponds to the printed material. When the tension of the printed material is too high, the detection rod will move closer to the tension adjustment mechanism. When the tension of the printed material is relaxed, the detection rod will move closer to one end of the printed material under the action of the detection spring.

[0006] Furthermore, the tension adjustment mechanism includes a support frame, which is fixedly connected to the machine frame. A slider is slidably connected to the support frame, and a threaded rod is rotatably connected to the slider. The threaded rod is threadedly connected to the support frame.

[0007] Furthermore, a locking nut is threaded onto the threaded rod, and the locking nut is located at the top of the support frame.

[0008] Furthermore, a connecting frame is fixedly connected to the slider, and tension wheels are fixedly connected to both ends of the connecting frame.

[0009] Furthermore, a sliding groove is provided on the frame, and a tension wheel is slidably connected to the sliding groove.

[0010] Furthermore, an adjustment motor is fixedly connected to the frame, and a control rod is fixedly connected to one end of the adjustment motor near the detection rod, the control rod corresponding to the detection rod.

[0011] Furthermore, if the tension of the printed material is relaxed, the detection spring will play an elastic reset role. Since one end of the detection spring is fixed to the bearing sleeve that is rotatably connected to the support shaft, and the other end is fixed to the force detection cylinder, under the spring force, the force detection cylinder drives the detection rod to move towards the end closer to the printed material. Through the dynamic change of the position of the detection rod, the current tension state of the printed material can be fed back in real time, providing a basis for subsequent adjustment. Moreover, the force detection cylinder is hollowed out at the center of the printed material, which ensures contact with the printed material to detect tension while avoiding excessive interference to the transmission of the printed material.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. This utility model utilizes a tension detection mechanism, employing a detection rod, a detection spring, and a force detection cylinder to accurately and in real-time sense changes in the tension of printed materials. The tension adjustment mechanism can respond manually or automatically (in conjunction with an adjustment motor), adjusting the position of the tension wheel using components such as threaded rods and sliders to quickly and accurately correct the tension, effectively preventing wrinkles and stretching deformation of printed materials due to abnormal tension, and improving winding quality.

[0013] 2. The structural design of bearing sleeves, sliding grooves, etc., ensures smooth operation of the detection and adjustment components. The detection spring provides stable elastic feedback, the tension wheel has good guiding properties along the sliding groove, and the cooperation of all components reduces mechanical wear and operational deviations, allowing the equipment to work stably for a long time and reducing the risk of production interruption due to equipment failure.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0018] Example: Refer to Figures 1-5 A constant tension winding device for printed materials includes a frame 1, and further includes an unwinding roller 2 and a winding roller 3 rotatably connected to the frame 1. Printed materials 4 are mounted on both the unwinding roller 2 and the winding roller 3. A tension detection mechanism 5 and a tension adjustment mechanism 6 are fixedly connected to the frame 1. The tension detection mechanism 5 includes a support shaft 51 fixedly connected to the frame 1. A detection rod 52 is slidably connected through the support shaft 51. A bearing sleeve 53 is rotatably connected to the support shaft 51. A detection spring 54 is fixedly connected to the bearing sleeve 53. A force detection cylinder 55 is fixedly connected to the detection spring 54, and the outer wall of the force detection cylinder 55 corresponds to the printed materials 4.

[0019] The force detection cylinder 55 is hollowed out at the center of the printed matter 4, and one end of its detection rod 52 corresponds to the printed matter 4. When the tension of the printed matter 4 is too high, the detection rod 52 will move closer to the tension adjustment mechanism 6. When the tension of the printed matter 4 is relaxed, the detection rod 52 will move closer to one end of the printed matter 4 under the action of the detection spring 54.

[0020] The tension adjustment mechanism 6 includes a support frame 61, which is fixedly connected to the frame 1. A slider 62 is slidably connected to the support frame 61, and a threaded rod 63 is rotatably connected to the slider 62. The threaded rod 63 is threadedly connected to the support frame 61.

[0021] A locking nut 64 is threaded onto the threaded rod 63, and the locking nut 64 is located on the top of the support frame 61.

[0022] A connecting frame 65 is fixedly connected to the slider 62, and tension wheels 66 are fixedly connected to both ends of the connecting frame 65.

[0023] A slide groove 11 is provided on the frame 1, and a tension wheel 66 is slidably connected to the slide groove 11.

[0024] An adjustment motor 7 is fixedly connected to the frame 1. A control rod 8 is fixedly connected to one end of the adjustment motor 7 near the detection rod 52. The control rod 8 corresponds to the detection rod 52.

[0025] If the tension of the printed material 4 becomes loose, the detection spring 54 will play an elastic restoring role. One end of the detection spring 54 is fixed to the bearing sleeve 53, which is rotatably connected to the support shaft 51, and the other end is fixed to the force detection cylinder 55. Under the spring force, the force detection cylinder 55 drives the detection rod 52 to move closer to the end of the printed material 4. Through the dynamic change of the position of the detection rod 52, the current tension state of the printed material 4 can be fed back in real time, providing a basis for subsequent adjustment. Moreover, the force detection cylinder 55 is hollowed out at the center of the printed material 4, which ensures contact with the printed material 4 to detect tension while avoiding excessive interference to the transmission of the printed material 4.

[0026] This invention utilizes the rotational cooperation of the unwinding roller 2 and the rewinding roller 3 to transport the printed material 4 between the frames 1. During the transport process, it comes into contact with the outer wall of the force detection cylinder 55. When the tension of the printed material 4 changes, the detection mechanism starts to work. If the tension of the printed material 4 is too high, the printed material 4 will exert a squeezing effect on the detection rod 52. Since the detection rod 52 is slidably connected to the support shaft 51, under the squeezing force, the detection rod 52 will move closer to the tension adjustment mechanism 6.

[0027] If the tension of the printed material 4 becomes loose, the detection spring 54 will play an elastic restoring role. One end of the detection spring 54 is fixed to the bearing sleeve 53, which is rotatably connected to the support shaft 51, and the other end is fixed to the force detection cylinder 55. Under the spring force, the force detection cylinder 55 drives the detection rod 52 to move closer to the end of the printed material 4. Through the dynamic change of the position of the detection rod 52, the current tension state of the printed material 4 can be fed back in real time, providing a basis for subsequent adjustment. Moreover, the force detection cylinder 55 is hollowed out at the center of the printed material 4, which ensures contact with the printed material 4 to detect tension while avoiding excessive interference to the transmission of the printed material 4.

[0028] When manual tension adjustment is required, the operator rotates the threaded rod 63. Because the threaded rod 63 is threadedly connected to the support frame 61 fixed on the frame 1, according to the principle of thread transmission, the rotation of the threaded rod 63 will cause the slider 62 connected to it to slide on the support frame 61. The connecting frame 65 fixedly connected to the slider 62 will move accordingly, thereby changing the spatial position of the tension wheels 66 at both ends of the connecting frame 65. After the position of the tension wheels 66 changes, it will affect the tension of the printed material 4, thus achieving tension adjustment. After adjustment, the locking nut 64 located on the top of the support frame 61 on the threaded rod 63 can be tightened. The threaded locking action of the nut and the threaded rod 63 will lock the position of the threaded rod 63, keeping the slider 62 and the tension wheels 66 in the adjusted state, ensuring tension stability. At the same time, the slide groove 11 opened on the frame 1 provides a guide track for the sliding of the tension wheels 66, ensuring that the movement of the tension wheels 66 is smooth and stable, and avoiding deviation that affects the tension adjustment accuracy.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
