Description

Technical Field

[0001] This utility model relates to the field of tape winding, and in particular to a tension adjustment mechanism for tape winding. Background Technology

[0002] Tape processing and winding refers to the process of winding the produced tape into a roll. The main purpose of this process is to facilitate storage, transportation and use. The quality of tape winding directly affects the performance of the tape. Therefore, it is very important to choose a suitable winding method. During the winding process, it is necessary to control the tension and speed of the tape to ensure the winding quality.

[0003] The prior art utility model patent with publication number CN 208326841 U proposes a tension adjustment mechanism for tape winding. It uses an adjusting screw to drive the adjusting block to adjust the height steadily up and down, thereby adjusting the height of the fixedly installed tension wheel. This adjusts the tension of the tension wheel to adapt to the tension of the tape as the winding wheel continuously winds up the tape and increases in thickness, which is beneficial for stabilizing the winding operation.

[0004] However, since the tape passes over both the take-up and tensioning rollers simultaneously without a fixed roller to assist it, it is difficult to achieve synchronous stretching and relaxation of the tape when adjusting the height of the tensioning roller. This affects the accuracy and magnitude of tension adjustment, resulting in poor adjustment stability. Furthermore, it lacks the ability to flatten and limit the tape. Therefore, we need to upgrade and modify the existing technology to overcome these problems and shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a tension adjustment mechanism for tape winding, including a device body. The device body includes a worktable, fixed rollers, adjusting rollers, adjusting components, and limiting components. Two sets of fixed rollers are symmetrically arranged on both sides of the worktable. The adjusting roller is located on the upper inner side of the worktable and between the two sets of fixed rollers. A connecting frame is provided on the upper end of the adjusting roller, and two sets of guide holes are opened on the connecting frame. The adjusting component is installed above the worktable and its lower end is connected to the connecting frame. The limiting component is arranged on the connecting frame.

[0006] Furthermore, the adjustment assembly includes a fixing frame, a threaded rod is threaded through the middle of the fixing frame and an external knob is provided at the top of the threaded rod, and two sets of positioning holes are opened on both sides of the fixing frame, with two sets of positioning rods movably passing through the two sets of positioning holes respectively.

[0007] Furthermore, the limiting assembly includes a limiting roller, a rotating frame is connected to the limiting roller, two sets of guide rods are provided at the upper end of the rotating frame, a tension spring is sleeved on the outer side of the guide rod, and a limiting piece is provided at the top of the guide rod and the limiting piece is connected to the tension spring.

[0008] Furthermore, the fixing frame is fixed to the upper end of the workbench, the bottom of the threaded rod is rotatably connected to the connecting frame, and the bottom of the positioning rod is fixedly connected to the connecting frame and located on both sides of the threaded rod.

[0009] Furthermore, the guide rod moves through the guide hole, the limiting roller is located above the adjusting roller and below the connecting frame, and the bottom of the tension spring is connected to the upper end of the guide hole.

[0010] Furthermore, limit grooves are provided on both sides of the worktable, and limit blocks are provided on both sides of the adjusting roller, with the limit blocks sliding within the limit grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model includes a fixed roller, an adjusting roller, a connecting frame, a fixed frame, a threaded rod, an external knob, a positioning hole, and a positioning rod. The external knob controls the rotation of the threaded rod, which in turn drives the connecting frame and the adjusting roller to move vertically up and down. This allows for height adjustment of the adjusting roller, facilitating changes in the tension of the tape. The adjustment effect is more pronounced through the cooperation of the adjusting roller and two sets of fixed rollers, ensuring the tape is tightly wound and preventing loosening and peeling, thus guaranteeing the quality of the tape.

[0013] 2. This utility model incorporates a limiting component, a limiting roller, a rotating frame, a guide rod, a tension spring, and a limiting plate within the device. The limiting plate, in conjunction with the tension spring, controls the extension and retraction of the guide rod within the guide hole. The guide rod, in turn, drives the rotating frame and the limiting roller to extend and retract accordingly. This enables the device to achieve a bonding and limiting operation on the upper surface of the rewinding tape, facilitating the stability of the tape during winding, preventing problems such as wrinkles and curling edges, and improving the practicality of the device.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown in Figure 4, this embodiment provides a tension adjustment mechanism for tape winding, including a device body 1. The device body 1 includes a worktable 2, fixed rollers 3, adjusting rollers 4, adjusting components 5, and limiting components 6. Two sets of fixed rollers 3 are symmetrically arranged on both sides of the worktable 2. The adjusting rollers 4 are arranged on the upper inner side of the worktable 2 and are located between the two sets of fixed rollers 3. A connecting frame 42 is provided on the upper end of the adjusting rollers 4, and two sets of guide holes 43 are opened on the connecting frame 42. Limiting grooves 21 are opened on both sides of the worktable 2. Limiting blocks 41 are provided on both sides of the adjusting rollers 4, and the limiting blocks 41 slide within the limiting grooves 21. The limiting grooves 21 and the limiting blocks 41 cooperate to limit the lifting and lowering of the adjusting rollers 4, maintaining their movement range and stability. The adjusting components 5 are installed above the worktable 2 and connected to the connecting frame 42 at their lower end. The limiting components 6 are arranged on the connecting frame 42.

[0023] Preferably, the adjustment assembly 5 includes a fixing frame 51, a threaded rod 52 is threaded through the middle of the fixing frame 51 and an external knob 53 is provided on the top of the threaded rod 52, two sets of positioning holes 54 are opened on both sides of the fixing frame 51, and two sets of positioning rods 55 are movably inserted into the two sets of positioning holes 54 respectively. The fixing frame 51 is fixed to the upper end of the worktable 2, the bottom of the threaded rod 52 is rotatably connected to the connecting frame 42, and the bottom of the positioning rods 55 is fixedly connected to the connecting frame 42 and located on both sides of the threaded rod 52.

[0024] The threaded rod 52 is rotated by the external knob 53. The threaded rod 52 and the positioning rod 55 drive the connecting frame 42 and the adjusting roller 4 to rise and fall vertically, thereby realizing the height adjustment of the adjusting roller 4. This makes it easy to change the tension of the tape on the adjusting roller 4. With the cooperation of the adjusting roller 4 and the two sets of fixed rollers 3, the adjustment effect is more obvious. The tape can be rolled up tightly, avoiding loosening and peeling, thus ensuring the quality of the tape.

[0025] Preferably, the limiting assembly 6 includes a limiting roller 61, a rotating frame 62 connected to the limiting roller 61, two sets of guide rods 63 provided at the upper end of the rotating frame 62, a tension spring 64 sleeved on the outer side of the guide rod 63, a limiting piece 65 provided at the top of the guide rod 63 and the limiting piece 65 connected to the tension spring 64, the guide rod 63 movably passing through the guide hole 43, the limiting roller 61 located at the upper end of the adjusting roller 4 and the lower end of the connecting frame 42, and the bottom of the tension spring 64 connected to the upper end of the guide hole 43;

[0026] The guide rod 63 is controlled to extend and retract within the guide hole 43 by the cooperation of the limiting plate 65 and the tension spring 64. The guide rod 63 pushes the rotating frame 62 and the limiting roller 61 to extend and retract accordingly, thereby realizing the bonding and limiting operation of the upper surface of the winding tape. This facilitates the maintenance of the stability of the tape during winding, prevents problems such as wrinkles and curling edges of the tape, and improves the practicality of the device.

[0027] The working principle and process of this utility model are as follows: During use, the tape passes under the fixed roller 3 on one side, then around the adjusting roller 4 and the limiting roller 61, and finally exits from the lower end of the fixed roller 3 on the other side. When it is necessary to adjust the tape tension, the threaded rod 52 can be rotated by the external knob 53. The threaded rod 52 and the positioning rod 55 drive the connecting frame 42 and the adjusting roller 4 to rise vertically, thereby raising the height of the adjusting roller 4 and changing the tension of the tape. The two sides of the tape remain stationary under the limiting position of the fixed roller 3. Only the upper end of the adjusting roller 4 is stretched, resulting in a more obvious adjustment effect and preventing the tape from becoming loose or slack. When it is necessary to reduce the tension, the operation can be reversed. During use, the tape passes between the limiting roller 61 and the adjusting roller 4. The tension spring 64 and the limiting plate 65 will pull the guide rod 63 downward. The guide rod 63 drives the rotating frame 62 and the limiting roller 61 to move accordingly. The limiting roller 61 presses tightly against the upper surface of the tape, which can perform flattening and limiting operations on the tape, making it easier to maintain the flatness of the tape and the stability of the conveying, and preventing wrinkles or curling.
