Description

Technical Field

[0001] This application relates to the field of adhesive tape production, and in particular to an automatic feeding mechanism for adhesive tape production. Background Technology

[0002] Adhesive tape is widely used in industries such as electronics, packaging, printing, and hardware. Its production process generally includes adhesive coating, high-temperature drying, precision bonding, and slitting. After the tape roll is cut, it needs to be smoothly and quantitatively conveyed to the subsequent workstations by an unloading mechanism. The stability of the unloading process directly affects the appearance quality and dimensional accuracy of the finished product.

[0003] Existing feeding mechanisms generally employ simple conveyor belts with manual assistance. Due to the lack of effective lateral restraint and pressure mechanisms, the conveyor belt is prone to problems such as deviation, wrinkling, and stacking during transport due to uneven tension or loss of width control. This results in uneven edges on the finished product, affecting cutting accuracy and appearance quality. Furthermore, these mechanisms cannot adaptively adjust to conveyor belts of different widths, exhibiting poor versatility; the feeding rhythm relies on manual monitoring and intervention, leading to low production efficiency and difficulty in meeting the demands of continuous, high-speed production.

[0004] Based on this, we propose an automatic feeding mechanism for adhesive tape production to solve the above problems. Summary of the Invention

[0005] In order to solve the technical problems mentioned in the background art, this application provides an automatic feeding mechanism for the production of adhesive tape.

[0006] The automatic feeding mechanism for adhesive tape production provided in this application adopts the following technical solution: An automatic feeding mechanism for producing adhesive tape includes: The carrier frame has a conveying assembly at its top for conveying adhesive tape. Both sides of one end of the carrier frame are fixedly connected to uprights, and a feeding roller is rotatably connected between the two uprights. The top of the uprights and both sides of the middle part of the carrier frame are fixedly connected to support plates. The pressing assembly is mounted on the top of the pallet, and the straightening assembly is mounted on the inner side of the support frame. The pressing assembly at the support frame is used to cooperate with the conveying assembly and the straightening assembly to form an anti-accumulation transfer of the adhesive backing. The pressing assembly at the upright is used to cooperate with the feeding roller and the conveying assembly to form a pause and intermittent quantitative conveying of the adhesive backing.

[0007] By adopting the above technical solution, the conveyor belt can be controlled during the conveyor belt discharge process, avoiding phenomena such as loosening, accumulation, deviation, and wrinkling of the conveyor belt, greatly reducing manual intervention and effectively improving the conveyor belt discharge efficiency.

[0008] Optionally, the conveying assembly includes: Two conveyor rollers are rotatably connected to the inner side of the support frame, and a conveyor belt is assembled between the two conveyor rollers; A speed reducer A is fixedly connected to one side of the support frame. The power output end of the speed reducer A is fixedly connected to one of the conveying rollers. A drive motor A is fixedly connected to one side of the speed reducer A, and the output end of the drive motor A is fixedly connected to the power input end of the speed reducer A.

[0009] By adopting the above technical solution and starting the drive motor A, its power is transmitted to one of the conveyor rollers through the reducer A. Since the conveyor belt is assembled between the two conveyor rollers, when the conveyor rollers rotate, the adhesive tape can be conveyed forward with the help of the conveyor belt.

[0010] Optionally, the pressing assembly includes: Two uprights are fixedly connected to the two ends of the top of the support plate, and a mounting plate is fixedly connected between the top ends of the two uprights. A cylinder is fixedly connected to the top end of the mounting plate. The displacement block is vertically slidably connected between two columns. The output end of the cylinder is also fixedly connected to the displacement block. An adjusting rod is slidably connected longitudinally in the middle of the displacement block. One end of the adjusting rod is fixedly connected to a linkage rod, and the other end of the linkage rod is provided with a slot. An assembly rod is inserted into the inside of a slot, and an assembly plate is fixedly connected to the outside of the assembly rod. A pressure roller is rotatably connected to the outside of the assembly plate. An extension frame is fixedly connected to the outside of a linkage rod. A limit locking rod is slidably connected to one end of the extension frame away from the linkage rod, and the limit locking rod is also snapped into connection with an assembly rod. A guide rod is fixedly connected to one end of the limit locking rod. The mounting frame is fixedly connected to one side of the tray. The mounting frame has a guide slot, and the guide rod is movably connected inside the guide slot.

[0011] By adopting the above technical solution, the cylinder is activated to push the displacement block downward, thereby changing the vertical position of the pressure roller. When the pressure roller contacts the adhesive tape, it can press the adhesive tape onto the conveyor belt to prevent slack accumulation. When the pressure roller does not meet the usage conditions, the start cylinder pulls the displacement block upward to adjust it, and at the same time changes the position of the guide rod inside the guide groove. As the guide rod continues to adjust, when the guide rod reaches the inclined section of the guide groove, the limit lock rod will disengage from the assembly rod as the guide rod adjusts along the inclined section of the guide groove. Then, the assembly rod can be pulled out from the slot, and the pressure roller can be removed from the linkage rod.

[0012] Optionally, the correction component includes: A transmission frame is fixedly connected to the inner side of the bearing frame. A central shaft is rotatably connected to the middle of the transmission frame. Threaded sections are provided at both ends of the outer side of the central shaft, and the threads of the two threaded sections have opposite directions. A transmission motor is fixedly connected to one end of the transmission frame, and the output end of the transmission motor is also fixedly connected to the central shaft. Two displacement frames are threadedly connected to two threaded sections, and a lateral limiting plate is fixedly connected to one end of the top of each displacement frame. Four extension plates are fixedly connected to both ends of two displacement frames. A positioning rod is fixedly connected to the end of each extension plate away from the displacement frame. A push frame is fixedly connected to the end of each positioning rod away from the extension plate. A linkage slot is provided on the push frame, and the linkage rod is also movably connected inside the corresponding linkage slot. A limiting component is mounted on the top of the displacement frame, and the limiting component restricts the movement of the adhesive-backed top surface.

[0013] By adopting the above technical solution, the drive motor is started to drive the central shaft to rotate. With the setting of two threaded sections with opposite directions on the central shaft, the two displacement frames can be driven to move closer or further apart during the rotation of the central shaft, thereby adjusting the distance between the two lateral limiting plates until the distance between the lateral limiting plates is adapted to the width of the adhesive tape. With the connection between the displacement frame and the extension plate, the position of the push frame can be adjusted by the positioning rod as the extension plate follows the adjustment of the displacement frame. Since the linkage rod is connected inside the linkage slot, when the position of the push frame changes, the linkage rod will be pushed synchronously by the push frame, causing the adjustment rod to be adjusted under the support of the displacement block until the distance between the two pressure rollers is adapted to the width of the adhesive tape.

[0014] Optionally, the limiting component includes: Two adjusting frames are slidably connected to the top of two displacement frames respectively. A top limiting plate is fixedly connected to the bottom of one end of each adjusting frame, and a guide column is fixedly connected to the other end of each adjusting frame. Two hollow shafts are rotatably connected to the bottom ends of two displacement frames. An eccentric plate is fixedly connected to the outer side of each hollow shaft. An adjustment slot is provided in the middle of the eccentric plate, and the guide column is also movably connected inside the corresponding adjustment slot. A drive shaft is rotatably connected to the inner side of the transmission frame, and two hollow shafts are slidably connected to the outer side of the drive shaft. A drive motor B is fixedly connected to the other end of the transmission frame, and the output end of the drive motor B is also fixedly connected to the drive shaft.

[0015] By adopting the above technical solution, the drive motor B is started to drive the drive shaft to rotate. With the connection between the drive shaft and the hollow shaft, the hollow shaft can rotate with the drive shaft and drive the eccentric plate to rotate. Since the guide post is connected inside the adjustment channel, during the rotation of the eccentric plate, the movement of the guide post inside the adjustment channel can help the adjustment frame to make adaptive adjustments until the top limiting plate contacts the top surface of the adhesive tape, thereby limiting the top surface of the adhesive tape.

[0016] Optionally, a bracket is fixedly connected to one end of the top of the support frame near the upright, a waste material winding roller is rotatably connected to the top of the bracket, a reducer B is fixedly connected to one side of the bracket, the power output end of the reducer B is fixedly connected to the waste material winding roller, a drive motor C is fixedly connected to the reducer B, and the output end of the drive motor C is fixedly connected to the power input end of the reducer B.

[0017] By adopting the above technical solution, the edge waste of the adhesive backing is connected to the waste take-up roller. At the same time as the waste is generated, the drive motor C is started, and the power of the drive motor C is transmitted to the waste take-up roller through the reducer B, thereby driving the waste take-up roller to rotate and wrap the edge waste around the waste take-up roller, so as to achieve effective collection of edge waste.

[0018] Optionally, each of the two uprights is fixedly connected to one side with a mounting lug, and a reversing roller is rotatably connected between the two mounting lugs.

[0019] By adopting the above technical solution, edge waste can be conveyed to the reversing roller under the transmission of the feeding roller, and then reversed at the reversing roller to effectively guide the edge waste, which is finally collected by the waste take-up roller.

[0020] Optionally, the assembly rod has a locking hole on the side facing the limiting lock rod, and the limiting lock rod is snapped into the inside of the locking hole.

[0021] By adopting the above technical solution, the assembly rod has space to accommodate the limiting lock rod. When the limiting lock rod moves towards the assembly rod, it can gradually be inserted into the locking hole, thereby achieving effective locking of the assembly rod.

[0022] Optionally, multiple support grooves are provided on the side of the lateral limiting plate away from the displacement frame and at the bottom of the top limiting plate, and rollers are rotatably connected inside the support grooves.

[0023] By adopting the above technical solution, when the side limiting plate and the adhesive backing are in contact, and when the top limiting plate and the adhesive backing are in contact, the adhesive backing can be limited without affecting the continued transfer of the adhesive backing, thereby ensuring the application effect of the side limiting plate and the top limiting plate.

[0024] Optionally, a limiting groove is formed on the outer side of the drive shaft, and a limiting strip is fixedly connected to the inner wall of the hollow shaft, and the limiting strip is also slidably connected inside the limiting groove.

[0025] By adopting the above technical solution, when the hollow shaft rod follows the displacement frame, the displacement of the hollow shaft rod will be guided by the limiting strip to avoid uncontrollable rotation of the hollow shaft rod. In the subsequent process of driving the shaft rod to rotate, the limiting strip can also drive the hollow shaft rod to rotate synchronously, avoiding motion interference.

[0026] In summary, this application includes at least one of the following beneficial technical effects: Through the cooperation of the pressing component and the conveying component, the cylinder drives the displacement block to move the pressure roller downward to press the tape, and stably adhere the adhesive tape to the conveyor belt, effectively suppressing the loosening and accumulation of the tape caused by uneven tension during the discharge process; the outer side of the pressure roller is fitted with a rubber ring, which has the functions of flexible buffering and friction retention, which can prevent indentations and scratches on the tape surface and ensure the appearance quality of the finished product. By setting up the alignment component, the drive motor drives the central shaft to rotate, and the two threaded sections with opposite directions drive the two displacement frames to move towards or away from each other. The spacing between the side limit plates and the lateral distance between the pressure rollers in the same group are adjusted synchronously to achieve adaptive alignment and limit for adhesive tapes of different widths. This effectively solves the problems of tape deviation and uneven edges during the conveying process and improves the versatility of the mechanism. Through the linkage between the eccentric plate and the adjusting frame in the limiting component, the drive motor B drives the eccentric plate to rotate. With the guidance of the guide column in the adjusting slot, the top limiting plate is driven to adaptively fit the top surface of the adhesive tape, thereby achieving limiting constraint on the thickness direction of the tape. Together with the side limiting plate, it forms a three-way limiting, which greatly reduces the probability of wrinkles and warping of the tape during transportation. By coordinating the waste rewinding roller and the reversing roller, the edge waste generated by slitting is guided by the reversing roller and then simultaneously rewound, realizing online automatic collection of waste, avoiding waste accumulation from interfering with the discharge process, reducing the frequency of manual cleaning, and further improving the continuity and cleanliness of the discharge operation.

[0040] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0041] This application discloses an automatic feeding mechanism for producing adhesive tape. (Refer to...) Figure 1 An automatic feeding mechanism for producing adhesive tape includes: The carrier frame 1 has a conveying assembly 2 at its top. The conveying assembly 2 is used to transfer the adhesive tape. The two sides of one end of the carrier frame 1 are fixedly connected to the uprights 3. The two uprights 3 are rotatably connected to the feeding rollers 4. The top of the uprights 3 and the two sides of the middle part of the carrier frame 1 are fixedly connected to the support plates 5. The pressing component 6 is mounted on the top of the pallet 5. The straightening component 7 is mounted on the inner side of the support frame 1. The pressing component 6 at the support frame 1 is used to cooperate with the conveying component 2 and the straightening component 7 to form an anti-accumulation transfer of the adhesive backing. The pressing component 6 at the upright frame 3 is used to cooperate with the feeding roller 4 and the conveying component 2 to form a pause and intermittent quantitative conveying of the adhesive backing.

[0042] Reference Figure 12 In this embodiment, a bracket 45 is fixedly connected to one end of the top of the support frame 1 near the upright frame 3. A waste material winding roller 46 is rotatably connected to the top of the bracket 45. A reducer B47 is fixedly connected to one side of the bracket 45. The power output end of the reducer B47 is fixedly connected to the waste material winding roller 46. A drive motor C48 is fixedly connected to the reducer B47, and the output end of the drive motor C48 is fixedly connected to the power input end of the reducer B47.

[0043] More specifically, the edge waste of the adhesive backing is connected to the waste take-up roller 46. At the same time as the waste is generated, the drive motor C48 is started, and the power of the drive motor C48 is transmitted to the waste take-up roller 46 through the reducer B47, thereby driving the waste take-up roller 46 to rotate and wrap the edge waste around the waste take-up roller 46 to achieve effective collection of edge waste.

[0044] Reference Figure 3 In this embodiment, each of the two uprights 3 is fixedly connected to one side of a mounting ear 49, and a reversing roller 50 is rotatably connected between the two mounting ears 49. More specifically, by using the lug 49 to support the reversing roller 50, the edge waste can be fed to the reversing roller 50 under the transmission of the feeding roller 4, and then reversed at the reversing roller 50 to effectively guide the edge waste, which is finally collected by the waste winding roller 46.

[0045] Reference Figure 3 In this embodiment, the conveying component 2 includes: Two conveyor rollers 8 are rotatably connected to the inner side of the support frame 1, and a conveyor belt 9 is assembled between the two conveyor rollers 8; The reducer A10 is fixedly connected to one side of the support frame 1. The power output end of the reducer A10 is fixedly connected to one of the conveying rollers 8. A drive motor A11 is fixedly connected to one side of the reducer A10, and the output end of the drive motor A11 is fixedly connected to the power input end of the reducer A10.

[0046] Reference Figure 4 In this embodiment, the pressing assembly 6 includes: Two uprights 12 are fixedly connected to the two ends of the top of the support plate 5 respectively. A mounting plate 13 is fixedly connected between the top ends of the two uprights 12. A cylinder 14 is fixedly connected to the top end of the mounting plate 13. The displacement block 15 is vertically slidably connected between the two columns 12. The output end of the cylinder 14 is also fixedly connected to the displacement block 15. An adjusting rod 16 is longitudinally slidably connected to the middle of the displacement block 15. One end of the adjusting rod 16 is fixedly connected to a linkage rod 17. The other end of the linkage rod 17 is provided with a slot 18. Assembly rod 19 is inserted into the inside of slot 18. Assembly plate 20 is fixedly connected to the outside of assembly rod 19. Pressure roller 21 is rotatably connected to the outside of assembly plate 20.

[0047] Reference Figure 5In this embodiment, a rubber ring is fitted on the outer side of the pressure roller 21. When in contact with the adhesive tape, the high elasticity and wear resistance of the rubber material can be used to achieve a gentle and stable pressure on the tape. This provides sufficient friction to ensure that the tape moves synchronously with the pressure roller 21 and prevents slippage and deviation. At the same time, the elastic deformation buffers and absorbs the tape thickness fluctuations and impact vibrations during the conveying process, avoiding the tape surface damage caused by direct pressure from the pressure roller 21, such as indentations, scratches or wrinkles. Thus, while ensuring the stability of the conveying process, the product quality of the adhesive tape is effectively protected.

[0048] Reference Figure 5 In this embodiment, a ball bearing is provided at the connection between the assembly plate 20 and the pressure roller 21. By providing the ball bearing, the friction of the pressure roller 21 when it rotates at the assembly plate 20 can be reduced, making the pressure roller 21 smoother.

[0049] Extension frame 22 is fixedly connected to the outside of linkage rod 17. One end of extension frame 22 away from linkage rod 17 is slidably connected to limit locking rod 23, and limit locking rod 23 is also snapped to assembly rod 19. One end of limit locking rod 23 is fixedly connected to guide rod 24. Reference Figure 6 In this embodiment, the assembly rod 19 has a locking hole on the side facing the limiting lock rod 23, and the limiting lock rod 23 is snapped into the inside of the locking hole; More specifically, by setting the locking hole, the assembly rod 19 has space to accommodate the limiting locking rod 23. When the limiting locking rod 23 moves towards the assembly rod 19, it can gradually be inserted into the interior of the locking hole, thereby effectively locking the assembly rod 19.

[0050] Reference Figure 5 In this embodiment, a clearance hole is provided at one end of the linkage rod 17 near the slot 18. By setting the clearance hole, the limiting locking rod 23 can pass through the clearance hole and enter the slot 18, so that the limiting locking rod 23 can be effectively assembled with the locking hole.

[0051] The mounting frame 25 is fixedly connected to one side of the support plate 5. The mounting frame 25 has a guide groove 26, and the guide rod 24 is also movably connected inside the guide groove 26. Reference Figure 4 In this embodiment, the top of the guide groove 26 bends away from the slot 18. Due to the structural characteristics of the guide groove 26, when the guide rod 24 reaches the inclined section of the guide groove 26, with the continuous adjustment of the displacement block 15, the movement of the guide rod 24 in the inclined section of the guide groove 26 will cause the limiting lock rod 23 to separate from the assembly rod 19, thereby unlocking the assembly rod 19.

[0052] Reference Figure 7In this embodiment, the correction component 7 includes: The transmission frame 27 is fixedly connected to the inner side of the bearing frame 1. A central shaft 28 is rotatably connected to the middle of the transmission frame 27. Threaded sections 29 are opened at both ends of the outer side of the central shaft 28, and the threads of the two threaded sections 29 are opposite in direction. A transmission motor 30 is fixedly connected to one end of the transmission frame 27, and the output end of the transmission motor 30 is also fixedly connected to the central shaft 28. Two displacement brackets 31 are threadedly connected to two threaded sections 29, and a lateral limiting plate 32 is fixedly connected to one end of the top of each displacement bracket 31. Four extension plates 33 are fixedly connected to the two ends of two displacement frames 31 respectively. A positioning rod 34 is fixedly connected to the end of the extension plate 33 away from the displacement frame 31. A pusher frame 35 is fixedly connected to the end of the positioning rod 34 away from the extension plate 33. A linkage slot 36 is opened on the pusher frame 35, and the linkage rod 17 is also movably connected inside the corresponding linkage slot 36.

[0053] More specifically, the internal fixed connection of the support frame 1 is a stabilizing slide bar, and the extension plate 33 is also slidably connected to the stabilizing slide bar. The stabilizing slide bar can effectively guide the displacement of the extension plate 33, prevent the extension plate 33 from undergoing uncontrollable displacement, and make the extension plate 33 more stable.

[0054] A limiting component is mounted on the top of the displacement frame 31, which restricts the movement of the adhesive top surface.

[0055] Reference Figure 9 In this embodiment, the limiting component includes: Two adjusting frames 37 are slidably connected to the top of two displacement frames 31 respectively. A top limiting plate 38 is fixedly connected to the bottom of one end of the adjusting frame 37, and a guide post 39 is fixedly connected to the other end of the adjusting frame 37. Reference Figure 10 In this embodiment, a stabilizing guide rod is vertically slidably connected to the top of the displacement frame 31, and the top end of the stabilizing guide rod is also fixedly connected to the adjustment frame 37. More specifically, by setting up the stabilizing guide rod, the vertical displacement path of the adjusting frame 37 can be guided, thus preventing the adjusting frame 37 from undergoing uncontrollable displacement.

[0056] Reference Figure 10 In this embodiment, multiple support grooves are provided on the side of the lateral limiting plate 32 away from the displacement frame 31 and at the bottom of the top limiting plate 38, and rollers are rotatably connected inside the support grooves. More specifically, by mounting the rollers with support grooves, the adhesive can be limited when the side limiting plate 32 contacts the adhesive and when the top limiting plate 38 contacts the adhesive, without affecting the continued transfer of the adhesive, thereby ensuring the application effect of the side limiting plate 32 and the top limiting plate 38.

[0057] Two hollow shafts 40 are rotatably connected to the bottom ends of two displacement frames 31 respectively. An eccentric plate 41 is fixedly connected to the outside of the hollow shaft 40. An adjustment slot 42 is opened in the middle of the eccentric plate 41, and the guide column 39 is also movably connected inside the corresponding adjustment slot 42. The drive shaft 43 is rotatably connected to the inner side of the transmission frame 27, and the two hollow shafts 40 are slidably connected to the outer side of the drive shaft 43. The other end of the transmission frame 27 is fixedly connected to the drive motor B44, and the output end of the drive motor B44 is also fixedly connected to the drive shaft 43.

[0058] Reference Figure 11 In this embodiment, a limiting groove is provided on the outer side of the drive shaft 43, and a limiting strip is fixedly connected to the inner wall of the hollow shaft 40, and the limiting strip is also slidably connected inside the limiting groove. More specifically, through the structural cooperation of the limiting strip and the limiting groove, when the hollow shaft rod 40 moves with the displacement frame 31, the limiting strip will guide the displacement of the hollow shaft rod 40 to avoid uncontrollable rotation of the hollow shaft rod 40. In addition, during the subsequent rotation of the drive shaft rod 43, the limiting strip can also drive the hollow shaft rod 40 to rotate synchronously to avoid motion interference.

[0059] The implementation principle of an automatic feeding mechanism for adhesive tape production according to an embodiment of this application is as follows: After the adhesive tape is discharged from the adhesive applicator, it is cut into the required specifications by the cutting tool. Then the cut adhesive tape is guided onto the conveyor belt 9 and the drive motor A11 is started. Its power is transmitted to one of the conveyor rollers 8 through the reducer A10. Since the conveyor belt 9 is assembled between the two conveyor rollers 8, when the conveyor rollers 8 rotate, the adhesive tape can be conveyed forward with the help of the conveyor belt 9. At the same time, the drive motor 30 is started to drive the central shaft 28 to rotate. With the setting of two threaded sections 29 with opposite directions on the central shaft 28, the two displacement frames 31 can be driven to move closer or further away from each other during the rotation of the central shaft 28, thereby adjusting the distance between the two lateral limiting plates 32 until the distance between the lateral limiting plates 32 is adapted to the width of the adhesive tape. With the connection between the displacement frame 31 and the extension plate 33, the position of the push frame 35 can be adjusted by the positioning rod 34 during the adjustment of the extension plate 33 following the displacement frame 31. Since the linkage rod 17 is connected inside the linkage slot 36, when the position of the push frame 35 changes, the linkage rod 17 will be pushed synchronously through the push frame 35, causing the adjusting rod 16 to be adjusted under the support of the displacement block 15 until the distance between the two pressure rollers 21 is adapted to the width of the adhesive tape. Then, the cylinder 14 is activated to push the displacement block 15 downward, thereby changing the vertical position of the pressure roller 21. When the pressure roller 21 contacts the adhesive tape, the adhesive tape can be pressed onto the conveyor belt 9 to prevent loose accumulation. Finally, under the guidance of the feeding roller 4, it is sent to the cutting process at the rear end, and the edge waste generated by cutting is connected to the waste take-up roller 46, and then collected by the waste take-up roller 46. Furthermore, the drive motor B44 can be started to drive the drive shaft 43 to rotate. In conjunction with the connection between the drive shaft 43 and the hollow shaft 40, the hollow shaft 40 can rotate with the drive shaft 43 and drive the eccentric plate 41 to rotate. Since the guide post 39 is connected inside the adjustment slot 42, during the rotation of the eccentric plate 41, the movement of the guide post 39 inside the adjustment slot 42 can cause the adjustment frame 37 to make adaptive adjustments until the top limit plate 38 contacts the top surface of the adhesive tape, thereby achieving the limit of the top surface of the adhesive tape. When the pressure roller 21 does not meet the usage conditions, the starting cylinder 14 pulls the displacement block 15 upward to adjust it. At the same time, it changes the position of the guide rod 24 inside the guide groove 26. As the guide rod 24 continues to adjust, when the guide rod 24 reaches the inclined section of the guide groove 26, the limit locking rod 23 will disengage from the assembly rod 19 as the guide rod 24 is adjusted along the inclined section of the guide groove 26. Then, the assembly rod 19 can be pulled out from the slot 18, and the pressure roller 21 can be removed from the linkage rod 17.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
