Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cutting equipment, in particular to a back adhesive cutting and slitting device. BACKGROUND

[0002] The back adhesive cutting and slitting device is an industrial equipment for precise cutting and slitting of back adhesive materials (such as back adhesive foam, rubber back adhesive, silicone back adhesive, etc.), and its core function is to divide the continuous back adhesive material into strips of specified width or length through mechanical or automatic means, and it is widely used in the fields of electronics, packaging, new energy, and optoelectronic materials. In actual production, due to the differences in the width specifications of back adhesive slitting for different products, it is necessary to adjust the distance between the cutting knives to adapt to diversified production needs.

[0003] A patent with publication number CN220128910U discloses a foam back adhesive slitting and cutting machine. In this utility model, the distance of the foam back adhesive body slitting is adjusted. After the distance of the cutting knife is adjusted, the staff passes a set of threaded rods through the circular holes and makes one end of the threaded rods abut against the inner wall of the bottom of the positioning groove. Then, the staff tightens and fixes the cutting knife through the cooperation between the nut and the threaded rod. The installation of the cutting knife is simple.

[0004] Although the above-mentioned scheme can adjust the distance between the knives, when adjusting the distance between the knives, in order to ensure the accuracy of the distance between the knives, the staff usually needs to use measuring tools (such as vernier calipers and rulers) to measure the distance between the knives. This manual measurement method is troublesome. When using the tools to measure, the tools need to be accurately adjusted and positioned, otherwise measurement errors are likely to occur, which will slow down the adjustment of the knives and affect the processing efficiency.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 7As shown in the embodiment of the present invention, an adhesive-backed cutting and slitting device includes a worktable 1. A control box 2 and a drive box 3 are fixedly installed on one side of the worktable 1. A drive shaft 4 is drivenly installed on the inner wall of the drive box 3. A positioning seat 5 is fixedly installed on the outer wall of the drive shaft 4 by a set fixing bolt. A sliding seat A6 and a sliding seat B7 are slidably installed on the outer wall of the drive shaft 4. Several sliding seats A6 are provided and located between the positioning seat 5 and the sliding seat B7. Cutting blades 8 are fixedly installed on the outer walls of the positioning seat 5, the sliding seat A6, and the sliding seat B7. A spacing adjustment component is provided between two adjacent cutting blades 8. When it is necessary to adjust the blade spacing between the cutting blades 8, the length of each spacing adjustment component is first adjusted. After the length adjustment of the spacing adjustment component is completed, the sliding seat B7 is pushed towards the positioning seat 5. Since the spacing adjustment component is intersected with the positioning seat 5, sliding seat A6, and sliding seat B7, when sliding seat B7 moves towards the positioning seat 5, it will push sliding seat A6 through each spacing adjustment component. Because the position of the positioning seat 5 is fixed, the spacing between each cutting blade 8 will be the length adjusted by the spacing adjustment component, thus achieving the effect of quickly adjusting the blade spacing. Traditional devices often require adjusting each blade individually when adjusting the blade spacing, which is cumbersome and time-consuming. However, this invention uses the sliding seat B7 to adjust the spacing by pushing the sliding seat B7. The coordinated action of the components enables rapid adjustment of the spacing between all cutting blades 8, significantly improving adjustment efficiency and reducing equipment downtime. This is particularly suitable for production scenarios requiring frequent blade spacing adjustments to accommodate different product specifications. The spacing adjustment component allows for precise length control. During adjustment, operators can accurately set the dimensions of the spacing adjustment component according to production requirements, ensuring that the spacing between each cutting blade 8 reaches the required precise value. This high-precision adjustment guarantees the quality of adhesive-backed cutting and reduces defects and waste caused by inaccurate blade spacing. Since the positioning seat 5 is fixed on the drive shaft 4, it provides a stable reference for the entire adjustment process, allowing adjustment by pushing the sliding seat B7. During the adjustment process, the cross-setting and interaction between the spacing adjustment components and each seat makes the adjustment process smoother, avoiding the wobble or deviation of the cutter during adjustment, ensuring the accuracy and reliability of the adjustment. The efficient cutter spacing adjustment reduces equipment downtime and manual adjustment costs. At the same time, the high-precision cutting reduces the scrap rate and reduces the waste of raw materials. These factors work together to help reduce the company's production costs and improve production efficiency. After the cutter spacing adjustment is completed, slide seats A6 and B7 are fixed. Then, the drive box 3 is started. The drive box 3 will rotate each cutting blade 8 through the drive shaft 4, so that the adhesive backing to be slit passes under the cutting blade 8 to complete the slitting work.

[0025] like Figures 3 to 7As shown, the spacing adjustment assembly includes an inner screw 9, an adjusting block 10 threaded onto the outer wall of the inner screw 9, and a fitting rod 11 fixedly mounted on the outer wall of the adjusting block 10. The outer walls of the positioning seat 5 and the sliding seat A6 are both provided with mounting grooves 12. A rotating shaft 13 is rotatably mounted on the inner wall of the mounting groove 12, and a rotating block 14 is rotatably mounted on the outer wall of the rotating shaft 13. The outer walls of the rotating blocks 14 are fixedly connected to one end of the inner screw 9. A scale is provided on the outer wall of the inner screw 9. When adjusting the length of the spacing adjustment assembly, rotating the adjusting block 10 causes the adjusting block 10 to engage with the threaded inner screw 9. When the adjusting block 10 moves, it drives the bonding rod 11 to move as well. The scale is used to move the bonding rod 11 to the appropriate position, thereby adjusting the total length of the bonding rod 11 and the inner screw 9. When adjusting the spacing of the cutting blades 8, the sliding seat B7 is pushed towards the positioning seat 5. The sliding seat B7 first engages with the adjacent bonding rod 11, and then each sliding seat A6 is pushed to engage with its corresponding bonding rod 11 in sequence, thus adjusting the blade spacing of the cutting blades 8. The inner screw 9 and the adjusting block 10 are installed using a threaded connection, and the threaded drive has… The precise displacement control characteristic allows the adjusting block 10 to move precisely in a straight line along the inner screw 9 when rotated. By controlling the number of rotations and angle of the adjusting block 10, the movement distance of the fitting rod 11 can be finely adjusted, thereby precisely controlling the total length of the spacing adjustment component. This provides a basis for the precise setting of the spacing of the cutting blade 8. The scale on the outer wall of the inner screw 9 provides the operator with an intuitive length reference. During the adjustment process, the operator can clearly read the movement position of the fitting rod 11 according to the scale, thus accurately adjusting the length of the spacing adjustment component to the required value. This avoids errors caused by visual inspection or experience judgment, greatly improving the precision and accuracy of the adjustment. When adjusting the length of the spacing adjustment component, the spacing adjustment component can be rotated outward by the cooperation of the rotating shaft 13 and the rotating block 14. This design provides a larger operating space when adjusting the length, avoiding the inconvenience caused by the small internal space of the device. The operator can rotate the spacing adjustment component to a suitable position and more conveniently rotate the adjusting block 10 to adjust the length, further improving the convenience and comfort of operation.

[0026] like Figures 5 to 6 and Figure 8As shown, a connector 15 is fixedly installed at the end of the fitting rod 11 away from the adjusting block 10. The outer walls of both sliding seats A6 and B7 have insertion slots 16, and the connector 15 is inserted into the inner wall of the insertion slot 16. The inner walls of both sliding seats A6 and B7 are equipped with snap-fit ​​components. When adjusting the spacing of the cutting blade 8, when the fitting rod 11 is fitted with sliding seat A6 or B7, the connector 15 will be inserted into the insertion slot 16, and the snap-fit ​​component will snap into the connector 15, fixing it in place. After the spacing adjustment is complete, the cooperation between the connector 15 and the snap-fit ​​component connects sliding seats A6 and B7 to the positioning seat 5, automatically fixing sliding seats A6 and B7 and avoiding the need for separate adjustments. The complex operation of fixing each tool not only reduces the difficulty of operation but also reduces problems such as loosening or inconsistent fixing due to multiple fixing points, improving the stability and reliability of tool fixing. The automatic fixing function simplifies the adjustment process and reduces operation time, thereby shortening the downtime of the equipment caused by tool distance adjustment. In modern production, equipment downtime directly affects production efficiency and output. Therefore, this design can significantly improve production efficiency and increase the economic benefits of enterprises. Since the insertion and snapping process is completed automatically while the sliding seat is being pushed to adjust the tool distance, the error rate caused by numerous operation steps is reduced, and production problems caused by forgetting to fix or not fixing securely are reduced, thus improving the stability and reliability of production.

[0027] like Figures 5 to 6 and Figures 8 to 10 As shown, the snap-fit ​​assembly includes a slide rod 17, with a snap-fit ​​connector 18 fixedly installed at one end of the slide rod 17. The snap-fit ​​connector 18 snaps into the plug connector 15. Limiting blocks 19 are symmetrically fixedly installed on the outer wall of the snap-fit ​​connector 18. Receiving grooves are provided on the inner walls of both the sliding seats A6 and B7. The slide rod 17, snap-fit ​​connector 18, and limiting blocks 19 are all slidably connected to the inner wall of the receiving groove. An elastic element 20 is fixedly installed between the snap-fit ​​connector 18 and the receiving groove, located on the outer side of the slide rod 17. An anti-slip pull head 21 is fixedly installed at the end of the slide rod 17 away from the snap-fit ​​connector 18. When the plug connector 15 enters the plug groove 16, the plug connector... 15 will squeeze the locking connector 18 to move it away from the plug 15. At this time, the elastic element 20 will contract. When the plug 15 enters the deepest position of the plug groove 16, the locking connector 18 will be reset under the action of the reverse elastic force of the elastic element 20. After being reset, the locking connector 18 will lock the plug 15, thereby fixing the plug 15. When it is necessary to remove the plug 15, simply pull the anti-slip pull head 21. The anti-slip pull head 21 will drive the locking connector 18 away from the plug 15 through the slide rod 17, thereby releasing the restriction on the plug 15. At this time, the plug 15 can be removed.

[0028] like Figures 2 to 3 and Figure 11As shown, a sliding plate 22 is provided above the workbench 1. A translation plate 23 is slidably mounted on the outer wall of the sliding plate 22. An extrusion seat 24 is fixedly mounted on the bottom of the translation plate 23. The extrusion seat 24 is located on the side of the sliding seat B7 away from the sliding seat A6. A drive assembly is provided on one side of the drive shaft 4. The extrusion seat 24 is positioned on one side of the sliding seat B7 via the translation plate 23 and the sliding plate 22. When it is necessary to push the sliding seat B7 to adjust the spacing of the cutting blade 8, the drive assembly is activated. The drive assembly will drive the extrusion seat 24 to move towards the sliding seat B7 via the translation plate 23. When the extrusion seat 24 moves, it will push the sliding seat B7 to move. The operator only needs to control the parameters of the drive assembly. This allows for the adjustment of the cutting blade 8 spacing without the need for manual pushing of the sliding block B7, greatly simplifying the operation process and saving time and effort. It is especially suitable for production scenarios that require frequent blade spacing adjustments. It avoids operators manually pushing the sliding block B7 to adjust the blade spacing, reducing contact between operators and moving parts, lowering the risk of hand injuries due to improper operation or accidents, and improving operational safety. Compared to manual adjustment, automated adjustment avoids human error caused by differences in operator skill level and experience. Whether operated by experienced or novice operators, it ensures the consistency and accuracy of the cutting blade 8 spacing adjustment, improving the product qualification rate.

[0029] like Figures 2 to 3 and Figure 11 As shown, the drive assembly includes two support frames 25, which are fixedly installed on both sides of the worktable 1. A sliding plate 22 is fixedly installed between the two support frames 25. A traveling screw 26 is rotatably installed between the support frames 25. A drive motor 27 is fixedly installed on one side of one of the support frames 25. The output end of the drive motor 27 is fixedly connected to one end of the traveling screw 26. The inner wall of the translation plate 23 is threadedly connected to the outer wall of the traveling screw 26. When the drive motor 27 is started, it will drive the traveling screw 26 to rotate. When the traveling screw 26 rotates, the translation plate 23 cannot rotate due to the restriction of the sliding plate 22. Therefore, the translation plate 23 will move through the threaded engagement between the traveling screw 26 and the translation plate 23. When the translation plate 23 moves, it will drive the extrusion seat 24 to move, providing power to push the sliding seat B7.

[0030] like Figures 2 to 3As shown, a support base 28 is provided on one side of the workbench 1. The inner wall of the support base 28 is rotatably connected to one end of the drive shaft 4. Mounting plates 29 are symmetrically fixedly installed on the outer wall of the support base 28. The mounting plates 29 are fixedly connected to the workbench 1 by mounting bolts 30. The two ends of the drive shaft 4 are supported by the drive box 3 and the support base 28 respectively. The support base 28 is fixed to the workbench 1 by the mounting plates 29 and mounting bolts 30. When it is necessary to replace the cutting blade 8, the mounting bolts 30 can be unscrewed to release the fixing of the mounting plate 29 to the workbench 1. Then, the support base 28 can be removed from the end of the drive shaft 4. After that, each cutting blade 8 can be removed from the drive shaft 4 for replacement.

[0031] like Figure 12 As shown, a lifting plate 31 is slidably installed on the inner wall of the extrusion seat 24. An automatic telescopic rod 32 is symmetrically fixed between the lifting plate 31 and the extrusion seat 24. Several ball bearings 33 are fixedly installed on the inner wall of the lifting plate 31. When the cutting blade 8 is removed, the automatic telescopic rod 32 is activated to extend. The extension of the automatic telescopic rod 32 will push the lifting plate 31 upward. After the lifting plate 31 moves upward, the ball bearings 33 will fit against the drive shaft 4, thereby supporting the drive shaft 4 and preventing the drive shaft 4 from being damaged due to lack of support after the support seat 28 is removed. After the support seat 28 is removed, the fixing of the positioning seat 5 is released first, and then the drive motor 27 is started to move the extrusion seat 24. When the extrusion seat 24 moves, it will push the sliding seat B7, thereby pushing the positioning seat 5, the sliding seat A6 and the sliding seat B7 off the drive shaft 4, which facilitates the removal of the cutting blade 8. The ball bearings 33 convert the sliding friction into rolling friction, thereby preventing damage to the drive shaft 4.

[0032] like Figures 4 to 5 , Figure 7 and Figure 13 As shown, both the positioning seat 5 and the sliding seat A6 have grooves 34 on their outer walls. A slider 35 is slidably installed on the inner wall of the groove 34. An arc-shaped limiting plate 36 is fixedly installed on the outer wall of the slider 35. The arc-shaped limiting plate 36 is in contact with the rotating block 14. After the length of the spacing adjustment component is adjusted, the spacing adjustment component is rotated to the horizontal position. Then, the arc-shaped limiting plate 36 is slid towards the rotating block 14. After sliding, the arc-shaped limiting plate 36 will be in contact with the rotating block 14, thereby limiting the rotating block 14 and preventing the spacing adjustment component from rotating and causing misalignment during subsequent adjustment.

[0033] like Figures 7 to 8 and Figure 14As shown, a positioning groove 37 is provided on the outer wall of the drive shaft 4. Positioning strips 38 are fixedly installed on the inner walls of the positioning seat 5, sliding seat A6, and sliding seat B7. The outer walls of the positioning strips 38 are slidably connected to the inner walls of the positioning grooves 37. The sliding seats A6 and B7 are connected to the drive shaft 4 through the positioning strips 38 and the positioning grooves 37, thereby increasing the connection strength between the sliding seats A6 and B7 and the drive shaft 4. This allows the drive shaft 4 to stably drive the sliding seats A6 and B7 to rotate when it rotates. At the same time, the positioning strips 38 and the positioning grooves 37 limit the positioning seats 5, sliding seats A6, and sliding seats B7, keeping each connector 15 aligned with the connector slot 16, and preventing misalignment during spacing adjustment.
