Description

Technical Field

[0001] The utility model relates to the field of tape processing, in particular to an automatic positioning shaft part for a tape core tube. Background Art

[0002] The existing automatic positioning shaft part for a tape core tube relies on the direct contact and friction of a mechanical structure to achieve positioning. This method is easily affected by external factors such as wear and vibration, resulting in a decrease in positioning accuracy. As the use time increases, the positioning error gradually accumulates, ultimately affecting the winding effect and product quality.

[0003] In the existing design, the adjustment of the core tube position is usually relatively fixed, lacking flexibility and adaptability. Once the core tube size or material changes, it is often necessary to stop the machine for manual adjustment, which not only reduces production efficiency but also increases the operation difficulty and cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic positioning shaft part for a tape core tube, and solve the following technical problems: how to achieve high-precision automatic positioning of the core tube, and how to improve the flexibility and adaptability of the core tube position adjustment.

[0005] To solve the problems existing in the prior art, the technical solution adopted by the utility model is as follows:

[0006] An automatic positioning shaft part for a tape core tube includes a rotating roller. Spiral grooves are equidistantly arranged on the outer side of the rotating roller. An inner rod is arranged inside the rotating roller. The two ends of the rotating roller are rotatably connected to the inner rod. An active block is slidably connected to the outer side of the inner rod. Sliders are equidistantly and fixedly connected to the outer side of the active block. The sliders are slidably connected inside the corresponding spiral grooves. A slide rod is slidably connected inside the sliders.

[0007] Preferably, the slider and the active block are integrally arranged. An annular cavity is formed inside the active block. The bottom end of the slide rod is slidably inserted into the annular cavity. The slide rod can telescopically slide inside the slider and the active block.

[0008] Preferably, a micro air pump is installed on one side wall of the active block. The output end of the micro air pump is communicated with the annular cavity. The micro air pump can provide air pressure inside the annular cavity, thereby pushing the slide rod to slide inside the annular cavity, and further realizing the movement and positioning of the slider.

[0009] Preferably, the inner rod is prismatically arranged. The prismatical arrangement enables the active block to slide smoothly on the outer side of the inner rod and at the same time rotate synchronously with the inner rod.

[0010] Preferably, a gear is fixedly connected to the outer side of one end of the rotating roller, which is convenient for the rotating roller to be connected to external equipment or a transmission system.

[0011] Preferably, the two ends of the rotating roller are internally rotatably connected with rotating cylinders, and the rotating cylinders are fixedly connected to the outside of the inner rod. The design of the rotating cylinders makes the rotation of the inner rod in the rotating roller smoother and more stable, reducing friction and wear.

[0012] Preferably, the connection parts of the sliding blocks and the movable blocks extend outwards on both sides to form limiting blocks, and one side wall of each limiting block is attached to the inner wall of the rotating roller. The design of the limiting blocks limits the sliding range of the sliding blocks in the rotating roller, preventing the sliding blocks from slipping out of the spiral grooves or excessive sliding.

[0013] Compared with the related art, the utility model has the following beneficial effects:

[0014] Through the rotation of the rotating roller and the guidance of the spiral groove, the sliding block drives the movable block and the sliding rod to slide along the inner rod, thereby realizing the flexible adjustment of the position of the bobbin core. This non-contact adjustment method avoids the problems of wear and accuracy decline that may be caused by traditional mechanical positioning, and improves the convenience and accuracy of operation at the same time.

[0015] When the inner rod rotates synchronously with the rotating roller, the bobbin core rotates synchronously. This design ensures that the tape can be wound evenly and tightly on the bobbin core, which not only improves the winding efficiency, but also ensures the winding quality, reducing waste and defective rate caused by uneven winding.

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0022] The automatic positioning shaft part of the tape bobbin core has a rotating roller 1;

[0023] As Figures 1 to 4As shown, spiral grooves 11 are equidistantly provided on the outside of the roller 1, an inner rod 2 is provided inside the roller 1, both ends of the roller 1 are rotatably connected to the inner rod 2, a movable block 3 is slidably connected to the outside of the inner rod 2, a slider 4 is equidistantly fixedly connected to the outside of the movable block 3, the slider 4 is slidably connected to the corresponding spiral groove 11, and a slide rod 5 is slidably connected to the inside of the slider 4.

[0024] The core is sleeved on the outside of the roller 1 and is set at the movable block 3. The inner wall of the tape core is pressed by the telescopic slide rod 5 to position the core. When the inner rod 2 rotates synchronously with the roller 1, the core will also rotate synchronously with the roller 1. This rotation state is very suitable for tape winding operations, ensuring that the tape can be evenly and tightly wound on the core. When the roller 1 rotates and the inner rod 2 is stationary, the roller 1 rotates through the outer spiral groove 11 to guide the slider 4 to gradually move along the spiral path under the action of the rotational force, so that the slider 4 drives the movable block 3 to slide on the outside of the inner rod 2, and the core supported by the slide rod 5 slides on the outside of the roller 1 to adjust the position of the core.

[0025] like Figures 1 to 4 As shown, the slider 4 is integrally arranged with the movable block 3, and an annular cavity 31 is opened inside the movable block 3. The bottom end of the slide rod 5 is slidably inserted into the annular cavity 31, and air is inflated into the annular cavity 31 to push the slide rod 5 to move outward and prop it up, thereby pressing and fixing the core of the outer side of the roller 1.

[0026] like Figures 1 to 4 As shown, a micro air pump 6 is installed on one side wall of the movable block 3 , and the output end of the micro air pump 6 is connected to the annular cavity 31 . The micro air pump 6 controls the sliding of the slide rod 5 by inflating and deflating the annular cavity 31 .

[0027] like Figures 1 to 4 As shown, the inner rod 2 is arranged in a prismatic shape, so that the movable block 3 can slide smoothly on the outside of the inner rod 2 and at the same time, can rotate synchronously with the inner rod 2.

[0028] like Figures 1 to 4 As shown, a gear 7 is fixedly connected to the outer side of one end of the roller 1, and can be engaged with the gear 7 through an external driving device to achieve precise control and stable rotation of the roller 1.

[0029] like Figures 1 to 4 As shown, the two ends of the roller 1 are internally connected with a rotating drum 8, and the rotating drum 8 is fixedly connected to the outside of the inner rod 2 to ensure that the inner rod 2 can rotate freely inside the roller 1 without affecting the rotation of the roller 1.

[0030] like Figures 1 to 4 As shown, the connection between the slider 4 and the movable block 3 has limit blocks 9 extending to both sides, and one side wall of the limit block 9 fits against the inner wall of the roller 1, ensuring that the slider 4 can always remain in the predetermined spiral groove 11 during operation.

[0031] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
