Description

Technical Field

[0001] This invention relates to the field of roll material slitting technology, and in particular to a coreless roll material slitting and adhesive applicator. Background Technology

[0002] A roll slitting machine (non-sticky strip) is a device that cuts and rolls large-diameter rolls of material into multiple smaller-diameter rolls, involving slitting, cutting, and packaging.

[0003] Existing technology involves using an automatic slitting device to slit the rolls to a fixed length, then driving an integrated turret via a turret driver to approach the winding station. This allows the cutting device, tape pasting device, and tail roller device mounted on the integrated turret to complete the sealing of small-diameter rolls, eliminating the need for manual operation, thus improving sealing efficiency and eliminating safety hazards. However, this existing technology suffers from overly simple structures, poor reliability and stability. For example, the tape pasting device has poor tape pasting effect and cannot stabilize the tape pasting position, making pasting errors likely. Furthermore, the tail roller device lacks adaptability to the thickness of the roll material, easily causing excessive compression and affecting the rotation of the winding device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a coreless roll-to-roll adhesive applicator with a reliable structure and strong stability, addressing the shortcomings of the prior art.

[0005] This invention provides a coreless roll slitting and adhesive applicator, comprising: a wire-laying device for flattening the roll material; a buffer device coupled to the wire-laying device for receiving the roll material; a traction device coupled to the buffer device for advancing and unwinding the roll material by clamping and traction; a winding device coupled to the traction device for receiving the roll material advanced by the limiting traction device and winding the roll material by rotation; a pressing device coupled to the winding device for pressing the roll material wound on the winding device to limit the winding effect; a cutting device coupled to the winding device and the traction device for cutting the roll material between the winding device and the traction device; and an adhesive applicator coupled to the winding device for applying adhesive tape to the end of the rolled material wound on the winding device to fix the winding effect. The beneficial effects of the above technical solution are as follows: by integrating the wire sorting device, buffer device, traction device, winding device, pressing device, cutting device, and adhesive applicator, it achieves the function of dividing large rolls into smaller rolls. The buffer device can pre-unwind the roll material, effectively avoiding the defect of poor unwinding and flattening effect caused by the asynchronous operation of the traction device and the wire sorting device. The traction device can cooperate with the winding device to achieve stable and reliable feeding and cutting, effectively solving the problems of coreless winding and the inability to flatten during cutting. The winding device provides the function of coreless winding by limiting the roll material. The pressing device can adapt to changes in roll material thickness to solve the problem of excessive compression. The adhesive applicator can solve the problem of adhesive application stability, thereby realizing a coreless winding and adhesive applicator machine with reliable structure and strong stability.

[0006] In some embodiments, the winding device includes a rotary driver, a telescopic driver, and a winding chuck. The telescopic driver drives the winding chuck to limit the winding material, and the rotary driver drives the winding chuck to rotate to achieve winding of the winding material. The beneficial effect of the above technical solution is that by using a telescopic winding chuck to achieve advance and retraction, the winding material is placed in the winding chuck, thereby realizing the coreless winding function.

[0007] In some embodiments, the adhesive applicator includes an adhesive applicator first driver, an adhesive applicator second driver, a roll-up roller, an adhesive applicator head, a support platform, a cutter, and a blower. The roll-up roller is used to unwind a whole roll of adhesive tape. The blower provides airflow to laterally swing the longitudinally suspended end of the adhesive tape below the adhesive applicator head. The adhesive applicator first driver drives the adhesive applicator head to descend and press the laterally swinging end of the adhesive tape onto the surface of the roll material under the support of the support platform. The adhesive applicator second driver drives the unwind roller to descend synchronously with the adhesive applicator head during adhesive application and to rise and reset after adhesive application to unwind the tape roll to a preset length. The cutter cuts the adhesive tape after application. The beneficial effect of the above technical solution is that by keeping the tape laterally positioned by the blower, the tape can be reliably and stably adhered to the preset roll material position under the action of the adhesive applicator head, greatly improving the reliability and stability of adhesive application.

[0008] In some embodiments, the support platform is raised and lowered by a support actuator to support the suspended roll material as the adhesive applicator head descends to apply adhesive. The beneficial effect of this technical solution is that by actively raising the support platform to cooperate with the adhesive applicator head, it provides support for the roll material during adhesive application, greatly improving the reliability and stability of the adhesive application process.

[0009] In some embodiments, a pressure roller device coupled to the winding device is also included to limit the winding width. The pressure roller device includes a pressure roller driver and a pressure plate, the pressure plate being adjusted by the extension and retraction process controlled by the pressure roller driver to adjust the winding width. The beneficial effect of the above technical solution is that by limiting the winding width in advance through the pressure roller device, the problem of winding errors can be effectively avoided.

[0010] In some embodiments, the buffer device includes a buffer support, a fixed roller disposed on the upper part of the buffer support, and a movable roller disposed on the lower part of the buffer support. The movable roller is slidably mounted on a slide bar longitudinally disposed between the upper and lower parts of the buffer support via a slider. The beneficial effect of the above technical solution is that the buffer device uses the cooperation of the movable roller and the fixed roller to buffer a certain length of roll material.

[0011] In some embodiments, the pressing device includes a pressing bracket, a guide rod, a pressing driver, and a pressing head. The pressing bracket is provided with the guide rod. The pressing driver is mounted on the guide rod via a mounting block and can slide along the guide rod. The pressing head is mounted on the output shaft of the pressing driver. The pressing head has a blocking portion located outside the pressing bracket. The blocking portion is used to press against the outside of the pressing support during the retraction process controlled by the pressing driver, thereby relatively resetting the original position of the mounting block. The mounting block and guide rod combination assists in the retraction of the pressing head when a counter-thrust force is generated as the thickness of the roll material increases after the pressing head extends and contacts the roll material. The beneficial effect of the above technical solution is that by mounting the pressing driver on a slidable guide rod, the driven pressing head can adaptively adjust its position during the winding process, thereby cooperating with the continuous increase of the winding thickness.

[0012] In some embodiments, a receiving tray, coupled to the winding device, is also included to receive the slitting rolls that fall from the winding device. The beneficial effect of the above technical solution is that the receiving tray enables the collection of slitting rolls, achieving automated unloading.

[0013] In some embodiments, the traction device includes a traction driver, a slide rail, a sliding table, a chuck driver, and a traction chuck. The chuck driver is mounted on the sliding table, which is slidably mounted on the slide rail. The traction driver drives the sliding table to slide along the slide rail, while the chuck driver drives the traction chuck to clamp and release. The beneficial effect of the above technical solution is that the retraction of the coiled material after feeding is achieved by moving the traction chuck through the traction driver, thereby improving the reliability and stability of the structure.

[0029] like Figure 1 As shown, this embodiment of the invention provides a coreless roll slitting and adhesive applicator, which includes a wire sorting device 1, a buffer device 2, a traction device 3, a roll device 4, a pressing device 5, a cutting device 6, an adhesive applicator 7, a pressure roller device 8, and a receiving tray 9, which respectively realize the flattening of the roll, the buffering of the roll, the traction of the roll, the slitting and rewinding of the roll, the pressing during slitting and rewinding, the cutting after slitting and rewinding, the adhesive applicator and sealing after slitting and rewinding, the pressure roller during slitting and rewinding, and the unloading after slitting and rewinding. This embodiment integrates a wire sorting device 1, a buffer device 2, a traction device 3, a winding device 4, a pressing device 5, a cutting device 6, and an adhesive applicator 7 to achieve the function of dividing large rolls into smaller rolls. The buffer device 2 can pre-unwind the roll material, effectively avoiding the defect of poor unwinding and flattening effect caused by the asynchronous operation of the traction device 3 and the wire sorting device 1. The traction device 3 can work with the winding device 4 to achieve stable and reliable feeding and cutting, effectively solving the problems of coreless winding and the inability to flatten during cutting. The winding device 4 provides the function of coreless winding by limiting the roll material. The pressing device 5 can adapt to changes in roll material thickness to solve the problem of excessive compression. The adhesive applicator 7 can solve the problem of adhesive application stability, thereby realizing a coreless winding and adhesive applicator machine with reliable structure and strong stability.

[0030] like Figure 1-2As shown, the cable management device 1 of this embodiment is used for flattening the roll material. The cable management device 1 includes a cable management driver 10, a rotating shaft 11, a central mounting member 12, and several support plates 13. The several support plates 13 are radially assembled on the central mounting member 12 to form an unwinding frame. The central mounting member 12 is locked on the rotating shaft 11, and the rotating shaft 11 is controlled by the cable management driver 10 to rotate. Specifically, the central mounting member 12 is hexagonal in shape, with an inner mounting hole on each face, and each support plate 13 has an outer mounting hole. Through the assembly of the inner and outer mounting holes, a support plate 13 is mounted on each face of the central mounting member 12. The six support plates 13 are radially assembled as a whole, and the roll material is unwound by passing through the holes in the support plates 13.

[0031] like Figure 1 , 3 As shown, the buffer device 2 in this embodiment is coupled to the cable management device 1 and is used to receive the roll material. The buffer device 2 includes a buffer support 14, three sets of fixed rollers 15 disposed on the upper part of the support, and a movable roller 16 disposed on the lower part of the buffer support 14. The movable roller 16 is slidably mounted on a slide rod 18 longitudinally disposed between the upper and lower parts of the buffer support 14 via a slider 17. In this embodiment, the buffer device 2 uses the cooperation of the movable roller 16 and the fixed rollers 15 to buffer a certain length of roll material. After the roll material is released from the winding device 1, it first winds around one of the fixed rollers 15, then around the movable roller 16, and finally around the other two fixed rollers 15. During the process of the traction device 3 pulling the roll material forward, the roll material is subjected to traction force. After reaching a certain level, the movable roller 16 is lifted along the slide bar 18, so that the roll material behind the movable roller 16 can be pulled forward by the traction device 3, while the roll material in front of the movable roller 16 can be temporarily not unwound. After the movable roller 16 is lifted to a certain height, the traction device 3 stops pulling and loses the tension of the roll material on the movable roller 16. Then, the movable roller 16 descends and resets along the slide bar 18 under the action of gravity. At this time, since the roll material behind the movable roller 16 is no longer pushed forward, the movable roller 16 stretches the roll material in front of the movable roller 16 during the descent. At the same time, the winding device 1 rotates and unwinds. During the descent of the movable roller 16, the position sensor senses the height of the lifting and lowering, thereby triggering the winding device 1 to start unwinding.

[0032] like Figure 1 , 4As shown, the traction device 3 of this embodiment is coupled to the buffer device 2 and is used to advance the unwinding by clamping and traction of the roll material. The traction device 3 includes a traction driver 19, a slide rail 20, a sliding table 21, a chuck driver 22, and a traction chuck 23. The chuck driver 22 is mounted on the sliding table 21, and the sliding table 21 is slidably mounted on the slide rail 20. The traction driver 19 is used to drive the sliding table 21 to slide along the slide rail 20, while the chuck driver 22 is used to drive the traction chuck 23 to clamp and release. The chuck driver 22 includes an upper chuck driver 22 and a lower chuck driver 22, and the traction chuck 23 includes an upper chuck and a lower chuck. The upper chuck driver 22 controls the upper chuck, and the lower chuck driver 22 controls the lower chuck. The clamping and releasing of the roll material is achieved by controlling the opening and closing of the upper and lower chucks, and the upper and lower chucks are configured with an elongated shape. At the start of traction, the traction chuck 23 is driven by the chuck driver 22 to clamp the roll material. After clamping, the traction driver 19 drives the traction chuck 23 to slide horizontally along the slide rail 20 to the rear of the roll material chuck 26. At this time, the roll material chuck 26 has not yet extended, and the roll material is in a straight state. After the roll material chuck 26 extends and limits the roll material, the chuck driver 22 drives the traction chuck 23 to release the clamping of the roll material. Since the distance between the upper and lower chucks after release is greater than the outer diameter of the roll material chuck 26, the traction driver 19 resets the traction chuck 23 by passing over the roll material chuck 26 along the slide rail 20. After reset, the traction chuck 23 remains released. The next clamping time of the traction chuck 23 is after the winding is completed.

[0033] like Figure 1 , 5As shown, the winding device 4 in this embodiment is coupled to the traction device 3 and is used to receive the winding material pushed by the limiting traction device 3 and wind the winding material by rotation. The winding device 4 includes a rotary driver 24, a telescopic driver 25, and a winding chuck 26. The telescopic driver 25 is used to drive the winding chuck 26 to extend to limit the winding material and to retract it for unloading and loading. The rotary driver 24 is used to drive the winding chuck 26 to rotate to achieve winding of the winding material. In this embodiment, the advance and retraction are achieved through the telescopic winding chuck 26, and the winding material is placed in the winding chuck 26, thereby realizing the coreless winding function. The coil chuck 26 consists of two semi-circular rollers with a gap between them. This gap accommodates the coil material being fed. The direction of the gap aligns with the direction of the coil material, allowing it to smoothly enter and thus limiting its position. This limiting can be achieved in two ways: First, the semi-circular rollers rotate and wind up while maintaining the gap. Since the portion of the coil material gripped by the traction device 3 during feeding is located behind the coil chuck 26, a certain length of coil material remains between this gap and the traction end. During the rapid rotation of the coil chuck 26, the coil material can be quickly positioned. Second, to enhance the positioning of the coil material, an inclined guide seat can be used. As the two semi-circular rollers extend, the inclined guide seat causes them to move closer together, reducing the gap until the coil material is clamped and positioned.

[0034] like Figure 1 , 6As shown, the pressing device 5 in this embodiment is coupled to the winding device 4 and is used to press the roll material wound on the winding device 4 to limit the winding effect. The pressing device 5 includes a pressing bracket 27, a guide rod 28, a pressing driver 29, and a pressing head 30. The pressing bracket 27 is provided with the guide rod 28. The pressing driver 29 is mounted on the guide rod 28 via a mounting block 31 and can slide along the guide rod 28. The pressing head 30 is mounted on the output shaft of the pressing driver 29. The pressing head 30 has a blocking part 32 located outside the pressing bracket 27. The blocking part 32 is used to press against the outside of the pressing support during the retraction process controlled by the pressing driver 29 to relatively reset the original position of the mounting block 31. The mounting block 31 and the guide rod 28 are combined to assist the pressing head 30 in retraction when a counter-thrust force is generated as the thickness of the roll material increases after the pressing head 30 extends and contacts the roll material. In this embodiment, by mounting the pressure actuator 29 on the slidable guide rod 28, the driven pressure head 30 can adaptively adjust its position during the winding process to accommodate the continuous increase in winding thickness. At the start of winding, the pressure actuator 29 drives the pressure head 30 to extend from its original position so that the pressure head 30 contacts the surface of the winding clamp 26. During the continuous winding process of the winding clamp 26, as layers of material are continuously stacked, the thickness of the small roll continuously increases. If the pressure head 30 remains stationary during this process, it may generate a reaction force, increasing the friction with the material, which could easily damage the material or affect the rotational power of the winding clamp 26. Therefore, since the pressure head 30 is assembled on the mounting block 31 together with the pressure actuator 29, and the mounting block 31 is slidable on the guide rod 28, when the pressure head 30 is subjected to a reaction force, it can retract under the action of the mounting block 31 and the guide rod 28 (relative to the forward movement of the pressure head 30). The retraction distance depends on the effect of the reaction force; the greater the winding thickness, the greater the retraction distance, thereby achieving adaptive adjustment of the pressure spacing. Furthermore, in order to restore the original position during the next pressure operation, the mounting block 31, i.e., the pressure actuator 29, needs to be reset. In this embodiment, when the pressure head 30 retracts, the blocking part 32 of the pressure head 30 contacts the outer side of the pressure material support, generating a reaction force on the mounting block 31, causing the mounting block 31 to move forward and reset to its original position.

[0035] like Figure 1 , 7 As shown, the cutting device 6 in this embodiment is coupled to the winding device 4 and the traction device 3, and is used to cut the rolled material located between the winding device 4 and the traction device 3. The cutting device 6 includes a cutting driver 33, scissors 34, and a scissors 34 driver. The cutting driver 33 drives the scissors 34 to extend during cutting and retract after cutting. During cutting, the traction device 3 clamps and positions the rolled material, and the adhesive applicator 7 clamps and positions the rolled material (while simultaneously applying adhesive).

[0036] like Figure 1 , 8 As shown, the adhesive applicator 7 in this embodiment is coupled to the roll-up device 4 and is used to adhere and fix the adhesive tape at the end of the roll material wound by the roll-up device 4 to fix the winding effect. The adhesive applicator 7 includes an adhesive applicator first driver 35, an adhesive applicator second driver 36, a roll-up roller 37, an adhesive applicator head 38, a support platform 39, a cutter 40, and a blower 41. The roll-up roller 37 is used to wind up the entire roll of adhesive tape. The blower 41 is used to provide airflow to swing the longitudinally suspended end of the adhesive tape horizontally below the adhesive applicator head 38. The adhesive applicator first driver 35 is used to drive the adhesive applicator head 38 to descend and press the horizontally swinging end of the adhesive tape onto the surface of the roll material under the support of the support platform 39. The adhesive applicator second driver 36 is used to drive the roll-up roller to descend synchronously with the adhesive applicator head 38 during adhesive application and to rise and reset after adhesive application to release the roll of adhesive tape to a preset length. The cutter 40 is used to cut the adhesive tape after application. In this embodiment, the blower 41 keeps the tape horizontal, ensuring that the tape can be reliably and stably applied to the preset roll material position under the action of the applicator head 38, greatly improving the reliability and stability of the application. The support platform 39 is raised and lowered by the support driver 42 to support the suspended roll material when the applicator head 38 descends for application. By actively raising the support platform 39 and cooperating with the applicator head 38 to support the roll material during application, the reliability and stability of the application are greatly improved.

[0037] like Figure 1 , 9 As shown, the pressure roller device 8 in this embodiment is coupled to the winding device 4 and is used to limit the winding width. The pressure roller device 8 includes a pressure roller driver 43 and a pressure plate 44. The pressure plate 44 is controlled by the pressure roller driver 43 to adjust the winding width by controlling the extension and retraction process. In this embodiment, by limiting the winding width in advance through the pressure roller device 8, the problem of winding errors can be effectively avoided.

[0038] like Figure 1 As shown, the receiving tray 9 in this embodiment is coupled to the winding device 4 and is used to receive the slitting rolls that fall from the winding device 4. This embodiment uses the receiving tray 9 to collect the slitting rolls, thus achieving automated unloading.

[0039] The working principle of this invention embodiment: The roll material is flattened in the winding device 1, and manually stretched through the buffer device 2 to the forward traction device 3. The traction device 3 is activated to clamp the roll material and pull it forward to the rear of the roll material clamp 26. The roll material clamp 26 extends to limit the roll material. After limiting, the traction clamp 23 releases the clamp on the roll material and resets. The pressure head 30 extends to contact the surface of the roll material clamp 26, and the roll material clamp 26 starts to rotate to wind up. After winding to the preset length, the roll material clamp 26 stops rotating, the traction device 3 starts to clamp the roll material, and the adhesive applicator 7 starts. The adhesive applicator 38, supported by the support platform 39, lowers and applies the adhesive tape to the upper surface of the roll material. With the traction device 3, the adhesive applicator 38, and the support platform 39 all clamping the roll material, the shearing device 6 activates to cut the roll material. After cutting, the shears 34 retract. Then, after the adhesive applicator 38 resets, the cutter 40 cuts the tape. After cutting, the cutter 40 retracts. Next, the roll chuck 26 activates to continue winding, sealing the tail of the roll material and the tape under the action of the pressure head 30. Subsequently, the pressure head 30 resets, the roll chuck 26 retracts, and the slit rolls fall onto the receiving tray 9. Generally, the first slit roll is not considered a finished product; the second slit roll and subsequent rolls are considered finished products.
