Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding equipment for tape slitting. Background Technology

[0002] In the production process of self-adhesive labels, the entire tape is typically first wound onto a large mandrel. Then, when demand arises, it is cut and repackaged onto smaller mandrels for easier sales. Currently, there is a problem with the repackaging and winding process: existing rewinding mechanisms struggle to tightly wind the self-adhesive tape. For example, patent CN202121841606.X – a paper-winding device for self-adhesive label printing – uses a compression spring within a guide seat to ensure a tight fit between the extrusion head at the top of the push rod and the detachable take-up roller. This prevents the shear head from detaching during the tape's final cut, avoiding loosening and improving the efficiency of tape winding. However, while this patent incorporates an extrusion head and a detachable take-up roller, the tensioning mechanism still struggles to maintain the correct tape tension during winding. Furthermore, the take-up roller cannot automatically switch between winding positions, resulting in a low overall level of automation. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0028] Reference Figures 1 to 5 The illustrated winding equipment for tape slitting includes a frame 100, an unwinding mechanism 200, a tensioning and feeding mechanism 300, a winding and cutting device 400, a core-loading device 500, and a feeding device 600. The unwinding mechanism 200 is mounted on the frame 100 and is used to unwind self-adhesive tape. The tensioning and feeding mechanism 300 is mounted on the frame 100 and is used to tension and clamp the self-adhesive tape released by the unwinding mechanism 200. The winding and cutting device 400 includes a turntable 410 rotatably mounted on the frame 100, at least two winding rollers 420 rotatably mounted on the turntable 410, and a pressing mechanism. The cutting mechanism 430 and the pressing mechanism 440 are all arranged sequentially on the frame 100 along the rotation direction of the turntable 410. The cutting mechanism 440 can cut the self-adhesive tape that has been wound and tensioned by the feeding mechanism 300 on the winding roller 420 in the corresponding area. The pressing mechanism 430 can cooperate with the winding roller 420 in the corresponding area to wind up the self-adhesive tape tightly. The core-loading device 500 is arranged on the frame 100 and is used to put the core sleeve on the empty winding roller 420. The unloading device 600 is arranged on the frame 100 and is used to unload the self-adhesive roll that has been wound up on the winding roller 420.

[0029] Specifically, the unwinding mechanism 200 can be a conventional roll material unwinding structure, such as a material tray that can be rotated and mounted on the frame 100, with the roll material coaxially mounted on the material tray. In this application, the roll material is an adhesive roll material, and the unwinding operation of the unwinding mechanism 200 can be achieved by the active feeding of the tensioning feeding mechanism 300. Both the core-loading device 500 and the unloading device 600 can be multi-axis robots, and the core-loading device 500 can also be adapted to a vibrating feeding hopper. In fact, these two are not within the scope of protection of this application, so they will not be described in detail here.

[0030] The tape winding equipment of this application automatically unwinds self-adhesive tape through the unwinding mechanism 200; the tensioning and feeding mechanism 300 tensions and clamps the self-adhesive tape released by the unwinding mechanism 200, which helps ensure that the winding and cutting device 400 winds the self-adhesive tape tightly. Furthermore, the winding and cutting device 400 is equipped with a turntable 410, a pressing mechanism 430, a cutting mechanism 440, and multiple winding rollers 420. This design allows the winding rollers 420 to be transferred to different workstations to perform different tasks, facilitating switching and sequentially performing the winding, cutting, and tightening of the self-adhesive tape ends, thus improving winding efficiency. The core feeding device 500 and the unloading device 600 enable automatic core feeding and automatic unloading of the wound self-adhesive roll.

[0031] Reference Figures 1 to 3 As shown, the tensioning feeding mechanism 300 includes several tensioning rollers 310, all of which are rotatably mounted on the frame 100. Adhesive tape is wound around all the tensioning rollers 310. At least two tensioning rollers 310 are connected to drive motors 320, which are mounted on the frame 100. At least one corrective top pressure roller 330 is rotatably mounted on the frame 100. Each corrective top pressure roller 330 is adapted to the tensioning rollers 310 connected to the drive motors 320 and clamps and feeds the adhesive tape. The adhesive tape is folded back around all the tensioning rollers 310, which facilitates tensioning and reduces the space required for folding. It should be noted that the back side of the adhesive tape is wound around the tensioning rollers 310 to prevent the adhesive tape from sticking to the tensioning rollers 310. The corrective top pressure roller 330 actually contacts the front side of the self-adhesive tape, i.e. the sticky side. In order to reduce the actual adhesion force, the material used on the surface of the corrective top pressure roller 330 is non-sticky, such as high-density polyethylene or polytetrafluoroethylene. This structural design enables the corrective top pressure roller 330 to achieve stable and smooth feeding when it is used in conjunction with the corresponding tension roller 310 to clamp the self-adhesive tape.

[0032] Furthermore, to simplify the design and reduce costs, there are two drive motors 320. The two tension rollers 310 connected to the drive motors 320 are not adjacent. That is, there are other tension rollers 310 between the two tension rollers 310 connected to the drive motors 320. When the self-adhesive tape is wrapped around all the tension rollers 310, the two tension rollers 310 connected to the drive motors 320 are not the two tension rollers 310 that the self-adhesive tape directly wraps around.

[0033] Reference Figures 1 to 4 As shown, three take-up rollers 420 are evenly distributed on the turntable 410. The frame 100 is located on the outer periphery of the turntable 410 and has a first station 110, a second station 120, and a third station 130 arranged sequentially. The cutting mechanism 440, the pressing mechanism 430, and the feeding device 600 are respectively located on the first station 110, the second station 120, and the third station 130. The working end of the core-loading device 500 can fit the core sleeve onto the take-up roller 420 located on the third station 130. The first station 110, the second station 120, and the third station 130 are arranged in a ring. Every time the turntable 410 rotates 120°, one take-up roller 420 can be transferred from one station to the next station, and the other two take-up rollers 420 are also transferred to the next station synchronously. In this application, the third station 130 is the station for unloading and core loading, the first station 110 is the station for winding, that is, the station where the head of the self-adhesive tape is wound together with the core sleeve on the take-up roller 420, and the second station 120 is the station for winding the self-adhesive tape.

[0034] In the above embodiment, a take-up motor 450 is provided on the turntable 410 in the corresponding area of ​​each take-up roller 420. Each take-up motor 450 can drive the corresponding take-up roller 420 to rotate. A main motor (not shown) for driving the turntable 410 to rotate is provided on the frame 100. Each take-up motor 450 rotates independently to adapt to different working requirements. In order to facilitate the turntable 410 to achieve the correct rotation angle, a position sensor 180 that cooperates with the turntable 410 is provided on the frame 100. In fact, the position sensor 180 is electrically connected to the main motor. The control principle between the position sensor 180 and the main motor is actually a conventional technical means, which will not be described in detail here.

[0035] Reference Figure 4As shown, to better cut the self-adhesive tape, the cutting mechanism 440 includes a mounting frame 441, a cutting cylinder 442 mounted on the mounting frame 441, and a blade holder 443 mounted on the telescopic end of the cutting cylinder 442. The blade holder 443 is equipped with a cutting blade 444. The mounting frame 441 is mounted on the first station 110. When the cutting cylinder 442 extends, it drives the cutting blade 444 to cooperate with the take-up roller 420 located on the first station 110 to cut the self-adhesive tape. Simultaneously, the blade holder 443 presses the cut end of the self-adhesive tape firmly against the outer wall of the core sleeve on the take-up roller 420. When the take-up roller 420 on the second station 120 rotates a certain number of times, the control system in the background controls the cutting cylinder 442 to extend, thus using the cutting blade 444 to cut the self-adhesive tape located between the take-up roller 420 on the first station 110 and the take-up roller 420 on the second station 120. When the cutting cylinder 442 continues to extend, the cut end of the self-adhesive tape is pressed against the outer wall of the core sleeve on the take-up roller 420 located at the first station 110 by the cutter holder 443, so that the self-adhesive tape can be wound on the core sleeve.

[0036] Reference Figure 4 and Figure 5 As shown, in order to ensure that the self-adhesive tape is tightly wound onto the outer wall of the core sleeve, the pressing mechanism 430 includes a bracket 431, a slide rail 432 mounted on the bracket 431, a sliding seat 433 slidably mounted on the slide rail 432, and a V-block 434 oscillatingly mounted on the sliding seat 433. The bracket 431 is mounted on the second station 120. Pressure rollers 435 are rotatably mounted on both ends of the V-block 434. A tension spring 436 is provided between the sliding seat 433 and the V-block 434. A shock-absorbing and resetting component is connected between the sliding seat 433 and the bracket 431. The pressure rollers 435 are always pressed against the outer wall of the self-adhesive roll during the tape winding process, ensuring that the newly wound self-adhesive tape remains firmly attached to the outer wall of the already wound self-adhesive tape. The V-block 434 is designed primarily to facilitate the removal of the pre-wound adhesive roll from the working area of ​​the V-block 434 by the turntable 410. This is achieved by swinging the V-block 434 around its hinge point with the sliding seat 433. When avoiding the adhesive roll, the V-block 434 swings towards the third station 130. A tension spring 436 is designed to reset the V-block 434. In this application, the shock-absorbing reset component is a spring, adapted to the distance between the sliding seat 433 and the outer wall of the adhesive roll, i.e., adapted to the continuously increasing diameter of the adhesive roll. As the diameter of the adhesive roll increases due to continuous winding, the shock-absorbing reset component is continuously compressed, causing the sliding seat 433 to gradually move away from the take-up roller 420 on the second station 120.

[0037] Reference Figure 5As shown, a lifting cylinder 140 is installed on the frame 100 in the area of ​​the first station 110. A fixed seat 150 is provided on the lifting cylinder 140, and a mounting hole 160 is provided on the fixed seat 150. A rotating sleeve 170 is rotatably installed in the mounting hole 160. The lifting cylinder 140 can drive the rotating sleeve 170 to be fitted onto the upper end of the take-up roller 420 that is stopped at the first station 110. By synchronously positioning the take-up roller 420 at the first station 110 through the rotating sleeve 170, the position of the core sleeve can be guaranteed, so that the cutter 443 can press the cut end of the self-adhesive tape tightly against the outer wall of the core sleeve on the take-up roller 420. In practice, the lifting cylinder 140 only lowers the fixed seat 150 and mounts the rotating sleeve 170 onto the upper end of the take-up roller 420 when the cutter holder 443 presses the cut end of the adhesive tape firmly against the outer wall of the core sleeve on the take-up roller 420, ensuring the accurate spatial position of the core sleeve. At other times, the lifting cylinder 140 raises the fixed seat 150 to avoid interfering with the normal rotation of the turntable 410.

Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
