Description

Technical Field

[0001] This invention relates to the field of ribbon coiling machine technology, specifically to a coiling forming device for an automatic coiling machine without paper sheath or core tube. Background Technology

[0002] When webbing products are transferred or shipped as finished products, they need to be coiled into a disc shape. The working principle of the coiling machine is similar to that of the traditional winding machine. It uses a motor to drive a turntable and a webbing winding core cylinder installed on the turntable to rotate in order to coil the webbing.

[0003] Currently, when coiling webbing, each coil requires manual cutting of the webbing, removal of the coiled disc-shaped webbing, manual pulling of the webbing to the coiling position, and then continuing to drive the motor to coil it. This operation is intermittent and cumbersome. Summary of the Invention

[0004] The purpose of this invention is to provide a tape forming device for an automatic tape reeling machine without cardboard or core, so as to solve the above-mentioned technical problems.

[0016] Preferably, the pressure roller has an inclined surface on its outer periphery.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This equipment achieves automated continuous operation through the linkage of multiple components: the webbing conveyor assembly, with the help of the drive assembly, directionally conveys the webbing to the webbing positioning groove on the winding shaft. The positioning assembly clamps the webbing in the clamping areas of the upper and lower second guide rollers to complete the positioning. The first and second guide rollers cooperate with the extension rod through a one-way bearing, so that the webbing will not be pulled when the webbing conveyor assembly resets. The cutting assembly automatically cuts the webbing during the movement of the webbing conveyor assembly through the cooperation of the abutment plate and the abutment rod, without the need for manual interruption. At the same time, the drive assembly, through reciprocating threaded grooves, bevel gear meshing, and other structures, synchronously drives the positioning plate to move and the winding shaft to rotate in both forward and reverse directions, realizing a closed loop of the entire process of conveying, positioning, winding, and cutting, significantly reducing the cost of manual intervention and improving the efficiency of the webbing operation.

[0019] When the webbing is positioned and wound by the webbing positioning groove of the winding shaft and the inclined surface of the pressure roller, the webbing will be unable to continue winding after it reaches a certain diameter under the action of the pre-tightening component. As the winding shaft continues to rotate, it will drive the torsion sleeve in the connecting component to rotate, so that the groove is aligned with the second groove. Under the action of the third spring, it will move down quickly. The pressure roller is set vertically to avoid interference when the winding shaft moves down. After the winding shaft moves down and disengages from the webbing, the pre-tightening component will reset under the action of the fourth spring and squeeze the webbing out. The subsequent reset plate moves with the webbing conveyor component and abuts against the cone head to drive the winding shaft to rise and reset. The torsion sleeve will drive the winding shaft to reset again under the action of the torsion spring to clamp and position the webbing. This achieves the effect of the winding shaft automatically moving down when the webbing is finished and automatically rising after the webbing is removed. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-12 The present invention provides a technical solution:

[0037] The automatic tape winding machine without cardboard and core disclosed in this invention is a tape forming device that is used to realize the automated continuous winding, cutting and automatic connection of new starting ends of the tape. It does not rely on cardboard and core, which greatly improves the work efficiency. Its specific implementation is as follows.

[0038] See Figure 1 , 2 3. The entire equipment is based on a workbench 1. A turntable 2 is mounted above the workbench 1. A winding shaft 3 is mounted in the center of the turntable 2. The winding shaft 3 has a radially formed webbing positioning groove 4 for initial positioning of the webbing. A positioning plate 5 (with a groove for the webbing to pass through) is slidably mounted on the surface of the workbench 1 along the radial direction of the turntable 2. The workbench 1 has a positioning plate groove 58 for the positioning plate 5 to slide. The positioning plate 5 has recesses on both sides for the inner wall of the positioning plate groove 58 to be engaged. The side of the positioning plate 5 facing the winding shaft 3 is fixedly connected to... The extension rods 6 are symmetrically distributed vertically. A webbing conveying assembly 7 is installed on the side of the extension rods 6 near the winding shaft 3. A positioning assembly 8 for clamping the webbing is installed in the webbing positioning groove 4 of the winding shaft 3. A driving assembly 9 for driving the positioning plate 5 to move radially is also provided on the worktable 1. A cutting assembly 10 is installed on the extension rods 6 between the first guide roller group and the second guide roller group of the webbing conveying assembly 7. At the same time, a pre-tightening assembly 11 and a reset assembly 12 are correspondingly provided on the worktable 1. All the components cooperate with each other to complete the complete webbing operation process.

[0039] See Figure 1 , 23, 4, 5. To ensure the webbing starting end can be smoothly fed into the webbing positioning groove 4 after cutting, the specific structure is as follows: A fixed plate 13 is fixedly connected between the upper and lower extension rods 6 of the positioning plate 5. The cutting blade 101 of the cutting assembly 10 is slidably assembled in the blade groove 14 opened in the fixed plate 13. The fixed plate 13 is provided with a support rod groove 15 for the support rod 102 to slide. An expansion groove is provided on the inner wall of the support rod groove 15. An expansion plate 16 is provided at the expansion groove of the support rod 102. One end of the support rod 102 is fixedly connected to the cutting blade 101. A webbing opening 17 for the webbing to pass through is opened in the middle of the fixed plate 13. The fixed plate 13 is also equipped with a first spring 18. The first spring 18 is located in the expansion groove and is used to abut against the expansion plate 16. It is used to drive the abutment rod 102 to move away from the webbing opening 17. The end of the abutment rod 102 located outside the fixed plate 13 is machined with a bevel 19. A abutment plate 20 is fixedly installed on the worktable 1 at the position corresponding to the bevel 19. When the positioning plate 5 moves to a specific position, the abutment plate 20 abuts against the bevel 19, thereby pushing the abutment rod 102 to drive the cutting blade 101 to move towards the webbing opening 17 to achieve cutting (the cutting end of the cutting blade 101 can be set at an angle, which is beneficial for cutting the webbing).The first guide roller group of the webbing conveyor assembly 7 consists of two symmetrical first guide rollers 701. The two first guide rollers 701 are rotatably mounted between the upper and lower extension rods 6 through the cooperation of a first rotating shaft and a one-way bearing. The lower first rotating shaft extends downward to below the extension rod 6 and is fixedly fitted with a first gear 21. The worktable 1 is fixed with a base plate 22 on the side of the abutment plate 20 away from the winding shaft 3. The base plate 22 is provided with a first slide rod groove. A first slide rod is slidably arranged in the first slide rod groove. The end of the first slide rod located outside the base plate 22 is fixedly connected to a first rack that meshes with the first gear 21. The base plate 22 is provided with a tail plate groove 23 at the bottom end of the first slide rod groove. The tail end of the first slide rod is provided with a tail plate 24 that slides with the tail plate groove 23. A second spring is installed inside the tail plate groove 23. 25, used to provide a reset spring force for the first slide rod; the second guide roller group includes four sets of second guide rollers 702, which are symmetrically assembled in pairs on the side of the upper and lower sets of extension rods 6 that are close to each other, and are rotatably connected to the extension rods 6 through the cooperation of the second rotating shaft and the one-way bearing. The second rotating shafts on the upper and lower sides extend to the outer side of the extension rods 6 that are far away from each other, and are fixedly connected to the second gears 26. The worktable 1 is fixed with a U-shaped plate 27 at the position of the back plate 20 away from the base plate 22. The upper and lower sides of the U-shaped plate 27 are provided with second slide rod grooves 28. The second slide rod 29 slides through the second slide rod grooves 28. The second slide rod 29 is fixed with a second rack 30 that meshes with the second gear 26 at one end of the second slide rod 29 outside the U-shaped plate 27. A tail plate groove 23 is also provided at the bottom end of the second slide bar groove 28. The tail end of the second slide bar 29 is provided with a tail plate 24 that slides with the tail plate groove 23. A second spring 25 is also installed inside the tail plate groove 23 to provide a restoring force for the second slide bar 29. In the above, the first guide roller 701 and the second guide roller 702 are connected to the extension rod 6 through a one-way bearing to achieve unidirectional rotation. The webbing is only allowed to move towards the winding shaft 3 and is not allowed to move away from the winding shaft 3 relative to the first guide roller 701 and the second guide roller 702. After the cutting blade 101 cuts the webbing, the starting end of the webbing will be located between the first guide roller 701 and the second guide roller 702. During the movement of the webbing conveyor assembly 7, the first rack and the first gear 21 mesh for a certain distance, and the second rack 3 When the first gear 201 meshes with the second gear 26 for a certain distance, the starting end of the webbing can be conveyed to the side of the second guide roller 702 near the winding shaft 3 via a guide roller. This facilitates the subsequent positioning assembly 8 to position the webbing through the clamping area 59 between the second guide rollers 702. It should be noted that the internal structures of the first rack and second rack 30, the first gear 21 and second gear 26, the first slide rod and second slide rod 29, the base plate 22 and the upper and lower ends of the U-shaped plate 27 are all the same. Since the first guide roller 701 and the second guide roller 702 are only allowed to rotate in one direction, when the first gear 21 and the second gear 26 mesh with the first rack and the second rack 30 during reset, they cannot rotate. Through the elastic structure of the second spring 25, the rack can be avoided, preventing the gear and rack from jamming.

[0040] See Figure 2 , 6 The drive assembly 9 consists of a motor 901 and a drive rod 902. A vertical plate 31 is fixed to the bottom of the worktable 1. The motor 901 is fixed to the vertical plate 31 by bolts. The bottom of the positioning plate 5 extends downward to the bottom of the worktable 1. The positioning plate 5 has a shaft hole 32 for the drive rod 902 to pass through. A third one-way bearing 33 is fixedly installed in the shaft hole 32. A guide block 34 is fixed on the inner ring of the third one-way bearing 33. The drive rod 902 has a reciprocating thread groove 35 that matches the guide block 34. Through the cooperation between the guide block 34 and the reciprocating thread groove 35, the motor 901 drives the drive rod 902 to rotate, thereby driving the positioning plate 5 to move radially back and forth. When the drive rod 902 rotates in the opposite direction, it cannot drive the positioning plate 5 to move. A stabilizing plate 57 is provided at the bottom of the worktable 1. One end of the drive rod 902 is inserted into the stabilizing plate 57 and forms a rotatable connection.

[0041] See Figure 1 , 68, 9, The bottom of the coiled shaft 3 extends downward to below the worktable 1, and is connected and fixed to the first bevel gear 37 through the connecting assembly 39. The connecting assembly 39 includes a sleeve 391 and a torque sleeve 392. A horizontal plate 40 is fixedly connected to one side of the vertical plate 31. The sleeve 391 is rotatably mounted on the horizontal plate 40 through a bearing, and the bottom of the sleeve 391 is fixedly connected to the top of the first bevel gear 37. A shaft groove 41 for axial sliding of the coiled shaft 3 is opened in the middle of the sleeve 391. A sleeve groove 42 is opened at the top opening of the shaft groove 41. The torque sleeve 392 is rotatably mounted in the sleeve groove 42, and a torsion spring 393 is connected between the torque sleeve 392 and the inner wall of the sleeve groove 42. A groove 43 is integrally formed on the outer wall of the coiled shaft 3. A first groove 44 for sliding of the groove 43 is opened on the inner wall of the torque sleeve 392. A second groove 45 for sliding of the groove 43 is opened on the inner wall of the shaft groove 41. A groove is opened on the bottom inner wall of the shaft groove 41. The groove 46 contains a buffer disc 47 rotatably mounted on a bearing. The bottom end of the third spring 48 is fixed to the buffer disc 47, and the top end is fixed to the bottom of the winding shaft 3, used to pull the winding shaft 3. A second bevel gear 38 meshing with the first bevel gear 37 is sleeved on the drive rod 902. The second bevel gear 38 is connected to the drive rod 902 through the second one-way bearing 36 to ensure the unidirectionality of power transmission. When the drive rod 902 drives the positioning plate 5 to move, the second bevel gear 38 cannot drive the first bevel gear 37 to rotate. When the first bevel gear 37 rotates and drives the winding shaft 3 to rotate and wind the webbing, after the webbing is wound to the required diameter, the continued rotation of the winding shaft 3 will be interfered with by the pre-tightening component 11, thereby driving the torque sleeve 392 to rotate relative to the sleeve post 391, so that the groove 43 is aligned with the second groove 45. The winding shaft 3 will descend under the pulling force of the third spring 48 to facilitate the removal of the webbing reel. It should be noted that the turntable 2 is provided with a protrusion 56 into which the feed groove 43 is inserted. This allows the winding shaft 3 to slide along the axis of the turntable 2 and also drives the turntable 2 to rotate. When the winding shaft 3 moves downward relative to the turntable 2, the top end face of the winding shaft 3 will be located within the thickness of the turntable 2, thus preventing the feed groove 43 from separating from the protrusion 56.

[0042] See Figure 1 , 67. The pre-tightening assembly 11 includes a pressure plate 111 and a pre-tightening roller 112, which can limit the webbing from warping during winding. The pressure plate 111 is fixed to the top of the winding shaft 3 by an L-shaped plate 49. Two radially symmetrical sliding grooves 50 are provided on the bottom end face of the pressure plate 111. A slider 113 is slidably mounted in the sliding groove 50. Limiting rods 51 are integrally formed on both sides of the slider 113. The inner wall of the sliding groove 50 is provided with a limiting groove 52 that matches the limiting rods 51. The pre-tightening roller 112 is rotatably mounted on the bottom of the slider 113 by a rotating shaft. A fourth spring 114 is installed at one end of the sliding groove 50 located radially outside the pressure plate 111. One end of the fourth spring 114 abuts against the inner wall of the sliding groove 50, and the other end is connected to the slider 113 to provide pre-tightening force for the pre-tightening roller 112. The reset assembly 12 includes a reset rod 121 and a cone head 122. The reset rod 121 is fixed to the bottom of the winding shaft 3. The bottom end of the reset rod 121 passes through the sleeve post 391 and the first bevel gear 37 in sequence and extends to the bottom of the first bevel gear 37. The cone head 122 is welded and fixed to the bottom end of the reset rod 121. A reset plate 123 is fixedly connected to one side of the positioning plate 5. The position of the reset plate 123 corresponds to the cone head 122. It is used to abut against the cone head 122 when the positioning plate 5 moves, driving the winding shaft 3 to rise and reset. When the winding shaft 3 winds the webbing, as the diameter of the webbing disc expands until the pre-tightening roller 112 drives the slider 113 to move to the limiting position of the slide groove 50, the winding shaft 3 will not be able to continue winding the webbing and will move downward. After the winding shaft 3 moves downward, it will disengage from the webbing. Under the action of the fourth spring 114, the reset of the pre-tightening rollers 112 on both sides will push the webbing disc out, and the operator can take away the webbing disc.

[0043] See Figure 10 , 11 12. The pressure rollers 801 of the positioning assembly 8 are symmetrically assembled on both sides of the webbing positioning groove 4. The pressure rollers 801 are rotatably connected to the pressure rods 802. The coiled shaft 3 has a pressure rod groove 53 inside. The pressure rods 802 are slidably assembled in the pressure rod groove 53 along the radial direction of the coiled shaft 3. An elastic element 54 is installed in the pressure rod groove 53. The elastic element 54 is a fifth spring. The elastic element 54 drives the two pressure rollers 801 to press towards each other to position the end of the webbing fed by the webbing conveyor assembly 7. The outer periphery of the pressure rollers 801 is machined with a slope surface 55. When the second guide roller 702 feeds the webbing between the two pressure rollers 801, the webbing in the clamping area 59 will be squeezed by the inclined surface 55, causing the two pressure rollers 801 to move a small distance away from each other, so that the webbing in the clamping area 59 is pressed by the two pressure rollers 801. Since the axial direction of the pressure roller 801 is the same as the direction of the webbing feeding, after the webbing is fed in, the pressure roller 801 will not rotate when pressing the webbing. After the subsequent winding of the winding shaft 3 is completed, the pressure roller 801 can rotate again during the downward movement of the webbing without interfering with the downward movement of the winding shaft 3.

[0044] See Figure 1-12When the equipment is working, the end of the webbing to be coiled is passed through the preceding guide roller group into the webbing conveyor assembly 7. Then, the motor 901 starts the drive rod 902 to rotate forward. Through the cooperation of the reciprocating thread groove 35 on the drive rod 902 and the guide block 34 inside the third one-way bearing 33 (at this time, the third one-way bearing 33 will not rotate relative to the shaft hole 32), the positioning plate 5 is driven to move radially along the worktable 1 towards the coiling shaft 3. At this time, the drive rod 902 will not drive the second bevel gear 38 to rotate through the second one-way bearing 36. The webbing passes through the positioning plate 5, the first guide roller group, and the fixed... The fixed plate 13 and the second guide roller group, guided and conveyed by the first guide roller 701 and the second guide roller 702, enter the webbing positioning groove 4 of the winding shaft 3. Under the action of the elastic element 54, the pressure roller 801 of the positioning component 8 clamps the webbing through the clamping area 59 between the second guide rollers 702, thereby achieving the positioning of the webbing. The motor 901 continues to rotate in the forward direction, driving the webbing conveying component 7 to reset. Since the first guide roller 701 and the second guide roller 702 allow the webbing to be pulled towards the winding shaft 3, the first guide roller 701 and the second guide roller 702 will rotate when the webbing conveying component 7 resets without pulling the webbing.

[0045] After the webbing conveyor assembly 7 is reset (the reset position is: the abutment rod 102 is located on the side of the abutment plate 20 close to the winding shaft 3, but the abutment rod 102 can be as close to the abutment plate 20 as possible), the drive motor 901 reverses. At this time, the drive rod 902 will not drive the positioning plate 5 to move, and the second bevel gear 38 will drive the first bevel gear 37 to rotate, thereby driving the winding shaft 3 to rotate through the connecting assembly 39. As the winding shaft 3 rotates, the webbing is evenly wound on the winding shaft 3. During the winding process, the pre-tightening roller 112 of the pre-tightening assembly 11 is always pressed against the surface of the webbing under the action of the fourth spring 114 to ensure the tightness of the webbing winding. When the webbing is wound to the predetermined diameter, the winding shaft 3 continues to rotate, which will drive the torque sleeve 392 to rotate, so that the first groove 44 on the inner wall of the torque sleeve 392 is aligned with the second groove 45 on the inner wall of the shaft groove 41. Under the pulling action of the third spring 48, the winding shaft 3 moves downward quickly and disengages from the wound webbing. At this time, the drive motor 901 rotates in the forward direction, first driving the webbing conveying assembly 7 to move away from the winding shaft 3, so that the abutment rod 102 abuts against the abutment plate 20, and the cutting blade 101 cuts the webbing, completing the winding of a single roll of webbing. At the same time, the pre-tightening roller 112 is pushed out of the wound webbing under the reset action of the fourth spring 114, and the operator takes away the extruded webbing roll.

[0046] Motor 901 continues to rotate forward, and drive rod 902 drives positioning plate 5 to move towards the winding shaft 3 via reciprocating thread groove 35. Abutment rod 102 will abut against abutment plate 20 again (at this time, the webbing is located between the two sets of first guide rollers 701, and the cutting blade 101 will not cut the webbing). After passing abutment plate 20, abutment rod 102 on positioning plate 5 continues to move towards the winding shaft 3. During the movement, the cooperation of first gear 21 and first rack, and second gear 26 and second rack 30 will send the starting end of the webbing to the clamping area 59 at the second guide roller 702. Positioning plate 5 continues to move through cooperation with drive rod 902. The reset plate 123 on one side of positioning plate 5 and the abutment cone at the bottom of reset rod 121 When the heads 122 abut against each other, they push the winding shaft 3 to move upward and reset. After the groove 43 disengages from the second groove 45, the torque sleeve 392 drives the winding shaft 3 to reset under the action of the torsion spring 393 (during the movement of the winding shaft 3, the groove 43 never disengages from the first groove 44, so that the winding shaft 3 and the torque sleeve 392 remain in cooperation). The webbing conveyor assembly 7 sends the end of the webbing to the pressure roller 801 for positioning again. At the same time, the first guide roller 701 and the second guide roller 702, under the action of the one-way bearing, prevent the positioning plate 5 from pulling the webbing when resetting, so as to realize the automatic access of the new roll of webbing. This cycle completes the continuous winding operation. The whole process does not require cardboard and core, and no manual interruption is required, which greatly improves the operation efficiency.
