Description

Technical Field

[0001] This invention belongs to the field of product waste disposal technology, and specifically relates to a waste disposal auxiliary mechanism. Background Technology

[0002] In die-cutting multi-functional tape laminating waste removal machines, when products (such as tapes and films) pass through a scraper to peel off the base film, the scraper needs to maintain an inclined angle for effective scraping. Under the peeling force, the product body is prone to warping, wrinkling, or even stretching deformation, affecting waste removal quality and finished product yield. To solve this problem, existing technologies typically use two independent PET pressure belts in front of the scraper to press the product tape from above, suppressing warping deformation during the scraping process. However, this solution has significant shortcomings: both PET belts are disposable or short-life consumables, requiring frequent replacement under long-term operation, resulting in high material consumption; simultaneously, each PET belt requires independent installation and adjustment, increasing operating procedures and labor costs. Overall, the existing method of using two PET belts for auxiliary pressing suffers from high consumable costs and heavy maintenance burdens, urgently requiring a waste removal auxiliary mechanism that can effectively prevent product deformation and reduce operating costs.

[0007] Furthermore, a lower slider is provided between the lower end of the compression spring and the lower end face of the mounting cylinder. The lower end of the compression spring is fixed to the lower slider. A lower sliding post is provided on the lower surface of the lower slider. The upper end of the lower sliding post is fixed to the middle of the lower slider. The lower end of the lower sliding post passes through the lower end of the mounting cylinder. A third rotating shaft is provided below the lower end of the lower sliding post. The third rotating shaft is located in the mounting groove, and both ends of the third rotating shaft are rotatably connected to the fixed frame. A worm is provided on the part of the third rotating shaft below the lower sliding post. A worm wheel is provided above the worm and meshes with it.

[0016] like Figure 1 As shown, a waste discharge auxiliary mechanism is installed at the waste discharge section of a die-cutting multi-functional tape bonding waste discharge machine. It includes symmetrically arranged adjustment components, each comprising a fixed frame 1. The inner side of the fixed frame 1 has a first connecting rod 4 and a second connecting rod 5 arranged in an inverted V shape. The upper ends of the first connecting rod 4 and the second connecting rod 5 are rotatably connected to the upper end of the fixed frame 1. An adjustment plate 10 is provided on the outer side of the middle portion of the first connecting rod 4 and the second connecting rod 5. The adjustment plate 10 has a first adjustment groove 11. A first locking bolt 12 is provided in the middle portion of both the first connecting rod 4 and the second connecting rod 5, and both first locking bolts 12 are located within the first adjustment groove 11. The fixed frame 1... The middle part is provided with a second adjustment groove 3, the middle part of the adjustment plate 10 is provided with a second locking bolt 13, the second locking bolt 13 is located in the second adjustment groove 3, the lower end of the fixed frame 1 is provided with a machine platform fixing bolt 2, and the two sets of adjustment components are symmetrically arranged with a first rotating roller 6, a second rotating roller 7 and a third rotating roller 8 arranged in a triangle. The two ends of the first rotating roller 6 are rotatably connected to the upper end of the fixed frame 1, the two ends of the second rotating roller 7 are rotatably connected to the lower end of the first connecting rod 4, and the two ends of the third rotating roller 8 are rotatably connected to the lower end of the second connecting rod 5. The first rotating roller 6, the second rotating roller 7 and the third rotating roller 8 are provided with elastic belts 9.

[0017] When using this waste discharge auxiliary mechanism, firstly, fix the symmetrically arranged adjustment components to the waste discharge section of the die-cutting multi-functional tape bonding waste discharge machine using the machine base fixing bolts 2 (e.g., Figure 7 and Figure 8(As shown); then loosen the first locking bolt 12 in the middle of the first connecting rod 4 and the second connecting rod 5, and the second locking bolt 13 in the middle of the adjusting plate 10. First, adjust the angle of the first connecting rod 4 so that the second rotating roller 7 installed at its lower end rises and falls, thereby keeping the lower edge of the elastic belt 9 surrounding the first rotating roller 6, the second rotating roller 7 and the third rotating roller 8 parallel to the material belt plane, so as to ensure that the pressure is evenly distributed along the width direction during subsequent pressing. Next, while keeping the position of the first connecting rod 4 unchanged, pull the second connecting rod 5 down so that the third rotating roller 8 at its lower end is pressed down further. Since the elastic belt 9 has been adjusted to a parallel state, the downward pressure of the second connecting rod 5 will cause the belt to form an upward bend between the second rotating roller 7 and the third rotating roller 8, that is, to present a "︿" shape (the middle part towards the top). The top of the "︿" shaped section (arched upwards and downwards on both sides) faces the blade of the scraper, ensuring that the elastic belt 9 provides normal pressure from above when the scraper peels off the bottom film at an angle. The downward pressure of the second connecting rod 5 is repeatedly fine-tuned according to the product thickness and material until the ideal "︿" angle and belt tension are obtained. Then, the first locking bolt 12 and the second locking bolt 13 are tightened respectively to fix the connecting rod and the rotating roller relatively. After starting the die-cutting multi-functional tape bonding and waste discharge machine, the product material belt moves forward. Under the action of friction, the elastic belt 9 moves synchronously with the material belt and each rotating roller. Its "︿" shaped middle section flexibly presses the material belt that is about to enter the scraper area from above. When the scraper removes the bottom film, the belt provides continuous and uniform normal pressure to limit product deformation. The peeled bottom film is smoothly discharged from the gap between the scraper and the belt.

[0018] Compared to the existing structure that uses two PET compression belts (such as...) Figure 6 As shown in the diagram, this solution uses an elastic belt 9 and an adjustable triangular roller assembly to achieve continuous and uniform surface contact pressing, effectively offsetting the tangential force and lifting force generated during the tilting peeling of the scraper, and significantly improving the deformation problem of thin or soft products during the waste removal process. The flexible material of the elastic belt 9 avoids rigid indentations and surface scratches, improving product yield. By independently adjusting the parallelism between the belt and the material belt through the first connecting rod 4 and independently adjusting the pressing angle through the second connecting rod 5, the posture and tension of the pressing surface can be precisely controlled, adapting to material belts of different thicknesses, viscosities, and materials, ensuring that the belt and the material belt move synchronously without speed difference, improving waste removal reliability and operational stability. At the same time, the structure is compact, the adjustment is intuitive, and the self-locking is reliable, reducing maintenance frequency and downtime, and can adapt to higher-speed continuous production, reducing manual intervention and scrap rate.

[0019] like Figure 2 and Figure 3As shown, in one feasible embodiment, a first rotating shaft 14 and a second rotating shaft 15 are vertically and parallelly arranged on the upper part of the fixed frame 1. Both ends of the first rotating shaft 14 and the second rotating shaft 15 are rotatably connected to the fixed frame 1. The upper ends of the first connecting rod 4 and the second connecting rod 5 are rotatably connected to the first rotating shaft 14. The first rotating roller 6 is sleeved on the second rotating shaft 15. The upper end of the fixed frame 1 is provided with a mounting groove 17, and the upper end of the mounting groove 17 is provided with a mounting cylinder 18. The inside of the mounting cylinder 18 is provided with a compression spring 21, and the upper end of the compression spring 21 is provided with an upper slider 20. The upper slider 20 is slidably connected inside the mounting cylinder 18. The lower surface of the upper slider 20 is fixed to the upper end of the compression spring 21. The upper surface of the upper slider 20 is provided with an upper sliding post 19. One end of the upper sliding post 19 is fixed to the upper slider 20, and the other end of the upper sliding post 19 passes through the middle of the upper end face of the upper slider 20. The upper end of the upper sliding post 19 is provided with a rotating bearing 16. The outer ring of the rotating bearing 16 is fixed to the upper sliding post 19, and the inner ring of the upper sliding post 19 is fixedly connected to the end of the second rotating shaft 15.

[0020] During the linkage adjustment process, the total loop length of the elastic belt 9 changes accordingly due to the change in the positions of the second rotating roller 7 and the third rotating roller 8. Without a compensation structure, the operator needs to repeatedly try to adjust the angle of the linkage and the position of the tension wheel to find a balance between belt parallelism, downward angle, and tension. This often requires multiple disassemblies or fine adjustments to achieve the ideal state, which is time-consuming and laborious. In this solution, the compression spring 21 continuously pushes the upper slider 20, the upper sliding column 19, and the rotating bearing 16 upward, thereby driving the second rotating shaft 15 and the first rotating roller 6 to move upward as a whole. This upward movement automatically increases the center distance between the first rotating roller 6 and the second and third rotating rollers 8, thus compensating for the slack elastic belt 9 with tension in one go. The operator only needs to focus on leveling with the first linkage 4 and adjusting the angle with the second linkage 5, without having to worry about the belt tension, because the compression spring 21 will automatically provide and maintain a suitable tension after the linkage adjustment is completed. If the belt experiences slight stretching or fluctuations in belt thickness during operation, the spring can dynamically compensate through elastic deformation, ensuring that the belt remains in contact with the roller surface.

[0021] This structure, by setting compression springs 21 and sliding guide components at both ends of the second rotating shaft 15, achieves the following beneficial effects: First, it significantly simplifies the tension adjustment operation. In the traditional scheme without springs, after adjusting the parallelism and "︿" angle of the elastic belt 9, the belt often becomes loose. Operators need to repeatedly try adjusting the linkage position or adding additional tensioning rollers, and run multiple times to find the appropriate tension, which is time-consuming and laborious. In this scheme, the compression spring 21 automatically drives the first rotating roller 6 to move upward to compensate for the excess belt circumference. Operators can complete the linkage adjustment in one go, without repeated trial and error, significantly shortening the equipment debugging time and reducing the requirements for operator experience. Second, it achieves automatic tension maintenance. Even if the elastic belt 9 experiences slight stretching or material belt thickness fluctuations during equipment operation, the spring can compensate at any time through the floating displacement of the first rotating roller 6, preventing belt slippage or derailment, and ensuring the long-term stability of the waste discharge process. Third, the flexible compensation of the spring makes the contact force between the belt and the material belt gentle and uniform, avoiding overpressure deformation or premature belt fatigue that may be caused by rigid tensioning structures, and extending the service life of the belt and bearings. Fourth, the tension compensation structure and the linkage adjustment function work independently yet collaboratively—the linkage is responsible for determining the belt's posture and angle, while the compression spring 21 is responsible for automatically maintaining the belt's tension. The division of labor between the two is clear, making the adjustment process more intuitive and faster, and further reducing the frequency of equipment maintenance and the need for manual intervention.

[0022] like Figure 4 and Figure 5 As shown, in one feasible embodiment, a lower slider 22 is provided between the lower end of the compression spring 21 and the lower end face of the mounting cylinder 18. The lower end of the compression spring 21 is fixed to the lower slider 22. A lower sliding post 23 is provided on the lower surface of the lower slider 22. The upper end of the lower sliding post 23 is fixed to the middle of the lower slider 22. The lower end of the lower sliding post 23 passes through the lower end of the mounting cylinder 18, and a third rotating shaft 25 is provided below the lower end of the lower sliding post 23. The third rotating shaft 25 is located in the mounting groove 17. Furthermore, both ends of the third rotating shaft 25 are rotatably connected to the fixed frame 1. The part of the third rotating shaft 25 located below the lower sliding column 23 is provided with a worm gear 26. Above the worm gear 26 is a worm wheel 28 that meshes with it. The worm wheel 28 is rotatably connected in the mounting groove 17. The upper part of the worm wheel 28 is flush with the worm wheel 28, and an arc-shaped push block 29 is provided at the flush position. The lower plane of the arc-shaped push block 29 is fixed to the worm wheel 28, and the upper arc-shaped surface of the arc-shaped push block 29 abuts against the lower end of the lower sliding column 23.

[0023] When the operator needs to change the tension of the elastic belt 9, the third rotating shaft 25 is manually rotated. The third rotating shaft 25 drives the worm 26 to rotate, and the worm 26 drives the worm wheel 28 to rotate. The arc-shaped push block 29 fixed on the worm wheel 28 rotates accordingly. Since the upper surface of the arc-shaped push block 29 is a continuously changing arc surface, its contact point with the lower end of the lower sliding column 23 gradually rises or falls with the rotation of the worm wheel 28, thereby pushing the lower sliding column 23 upward or releasing it downward. The up-and-down movement of the lower sliding column 23 drives the lower end of the compression spring 21 to rise and fall via the lower slider 22, thereby changing the pre-compression of the compression spring 21: when the lower sliding column 23 is pushed upward, the compression spring 21 is further compressed, and the upward elastic force of the spring increases. This elastic force is transmitted to the second rotating shaft 15 through the upper slider 20, the upper sliding column 19, and the rotating bearing 16, which increases the force of the first rotating roller 6 pressing the elastic belt 9 upward, thereby increasing the belt tension. Conversely, when the lower sliding column 23 is released downward, the spring compression decreases, and the tension decreases. This adjustment process works in conjunction with the original automatic compensation function of the compression spring 21: the automatic compensation is used to absorb the "coarse adjustment" of belt slack, while the fine adjustment mechanism composed of the worm gear 28, worm 26, and arc-shaped push block 29 is used to manually, continuously, and with high precision set the tension. Moreover, the worm gear 28 and worm 26 have self-locking characteristics, and the position after adjustment will not change due to vibration or spring reaction force.

[0024] This structure, by adding a manual adjustment component driven by a worm gear 28, worm 26, and arc-shaped push block 29 to the lower end of the compression spring 21, achieves the following beneficial effects: First, it enables precise manual adjustment of the tension of the elastic belt 9. Operators can continuously change the spring compression by rotating the third shaft 25 according to different product materials, thicknesses, or belt aging levels. The tension change is smooth and controllable, and the self-locking performance of the worm gear 28 and worm 26 ensures stable position after adjustment, avoiding tension drift caused by loose threads or vibration in traditional tension adjustment. Second, it separates the automatic coarse compensation from the manual fine adjustment function: the automatic upward movement of the compression spring 21 eliminates the basic slack generated after linkage adjustment, allowing the belt to quickly conform to the roller surface without repeated trial and error; while the manual adjustment mechanism provides independent fine tension setting on this basis. Operators do not need to painstakingly adjust tension while leveling and adjusting angles, significantly reducing the difficulty and time of adjustment. Third, the arc-shaped pusher 29 converts rotational motion into precise linear displacement. Combined with the large reduction ratio of the worm gear 28 and worm 26, this results in extremely high tension adjustment resolution, making it particularly suitable for thin or high-precision tape products that are sensitive to pressure. It effectively prevents product indentation caused by excessive tension or belt slippage caused by insufficient tension. Fourth, the adjustment mechanism has a compact structure and is fully integrated into the mounting slot 17, without adding extra space to the equipment. The adjustment operation is intuitive (simply rotate the third rotating shaft 25) without disassembling any parts, greatly improving the convenience of equipment debugging and maintenance.

[0025] like Figure 2 As shown, in one feasible embodiment, a fixed base 24 is provided on the outer surface of the fixed frame 1. The end of the third rotating shaft 25 is rotatably connected to the fixed base 24. A fourth rotating shaft 27 is provided in the mounting groove 17, and both ends of the fourth rotating shaft 27 are rotatably connected to the side wall of the mounting groove 17. A worm gear 28 is fixed to the third rotating shaft 25. A turntable 30 is provided on one end of the third rotating shaft 25 and is fixed to the third rotating shaft 25, with the turntable 30 located outside the fixed base 24. This connection method is simple and reliable, and the turntable 30 facilitates manual rotation of the third rotating shaft 25.

[0026] like Figure 2 As shown, in one feasible embodiment, the elastic belt 9 is divided into several belt segments 33. The first rotating roller 6, the second rotating roller 7 and the third rotating roller 8 are each provided with an annular groove 31. Several slip rings 32 are provided in the annular groove 31. The slip rings 32 are provided with countersunk bolts. The countersunk bolts are used to fix the slip rings 32 in the annular groove 31. Several belt segments 33 are respectively wound around several slip rings 32.

[0027] The first rotating roller 6, the second rotating roller 7, and the third rotating roller 8 are all provided with annular grooves 31. Each annular groove 31 is provided with several sliding rings 32 that can slide along the groove direction. The sliding rings 32 are locked and fixed in the required position in the annular groove 31 by countersunk bolts. The original whole elastic belt 9 is divided into several independent belt segments 33 (i.e., multiple narrow belts). Each belt segment 33 is wound around a set of corresponding sliding rings 32 (the positions of the sliding rings 32 on the three rotating rollers are aligned one by one). When it is necessary to process product strips of different widths, the operator first loosens the countersunk bolts, moves the sliding rings 32 along the annular groove 31 according to the effective width of the strip, and adjusts the spacing between adjacent belt segments 33 so that the total coverage width of all belt segments 33 matches the width of the strip. At the same time, if the strip is narrow, it is also possible to choose to install only the required number of belt segments 33 (for example, only use the middle 2 to 3), and leave the other sliding rings 32 empty or move them to the edge. After adjustment, tighten the countersunk bolts to fix the slip ring 32, and then put each belt segment 33 onto the corresponding slip ring 32 set. When the equipment is running, each belt segment 33 operates independently and applies a pressing force to the material belt. However, since the segments are separated from each other, they only act on the effective area of ​​the material belt and will not cause unnecessary friction or indentation to the unloaded area outside the edge of the material belt.

[0028] This structure, by dividing the entire elastic belt 9 into several independent belt segments 33 and using adjustable slip rings 32, achieves the following beneficial effects: First, it significantly improves adaptability to belts of different widths. Operators no longer need to customize different specifications of the entire belt for each product width; they can quickly switch between segments simply by sliding the slip rings 32 to adjust the spacing between the belt segments 33, greatly reducing the types of spare parts and changeover time. Second, it allows for on-demand selection of the number of belt segments 33. For narrower belts, only a few middle belt segments 33 can be installed, avoiding interference with other equipment components or unnecessary energy consumption, while also reducing belt material waste. Third, it simplifies local maintenance and replacement. When a belt segment 33 is damaged, only that segment needs to be replaced without disassembling the entire wide belt, reducing maintenance costs and downtime. Fourth, it reduces the ineffective area of ​​the pressing force. Since the belt segments 33 only cover the actual width of the belt, it avoids the air pressure or scratching generated outside the belt edge area by the traditional whole belt, which is especially suitable for tape products with high edge quality requirements, further reducing the risk of product deformation. Fifth, the fixing method of slip ring 32 with countersunk bolt is convenient to adjust and reliable to lock, which can adapt to the frequent adjustment needs of different segment spacing, and the structure of annular groove 31 ensures the synchronous movement of each belt segment 33 without affecting the overall waste discharge effect.

[0029] In one feasible embodiment, the first locking bolt 12, the second locking bolt 13, and the machine base fixing bolt 2 all include a threaded rod and a locking nut. Specific configuration details are as follows: Figure 1 As shown, without going into too much detail here; in one feasible method, the arc-shaped push block 29 has an outwardly protruding wedge-shaped surface with a cross-section similar to a smooth triangle, so that it has a positional height difference and can play a regulatory role.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
