Description

Technical Field

[0001] This invention relates to the field of folding machine tool changing technology, specifically a tool changing and adjusting bracket for folding machine tool rollers. Background Technology

[0002] In a folding machine, the bladed roller is the main working component for cutting and shaping raw fabric. It is the primary component that folds and cuts the entire roll of nonwoven fabric into standard shapes according to the customer's product specifications. During years of operation, the high-speed steel blades mounted on the roller will wear down after prolonged cutting, or gaps may develop between several cutting blades after long-term operation. In such cases, replacement or adjustment of the gap is necessary.

[0003] When replacing the blades or adjusting the gap on the folding machine's cutter roller, the fixing parts on the cutter roller must first be removed so that the gears on the cutter roller are disengaged from the drive components on the folding machine. Then, the cutter roller must be moved from the working position to the maintenance position before the blades can be replaced or the gap adjusted.

[0004] However, the cutter roller weighs several hundred kilograms, and during operation, the roller and blades are constantly in a state of free rotation and sliding, making it difficult for operators to effectively fix the roller and increasing the difficulty of their work. Furthermore, the roller is prone to colliding with the operator's hands when it shakes, potentially causing injury. Therefore, we propose a blade changing and adjusting bracket for the cutter roller of a folding machine. Summary of the Invention

[0005] The purpose of this invention is to provide a tool changing and adjusting bracket for a folding machine cutter roller, which solves the problems in the prior art.

[0037] 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.

[0038] Example 1

[0039] Please see Figure 1 , Figure 2 as well as Figure 10 The present invention provides a technical solution:

[0040] A blade changing and adjusting bracket for a folding machine's blade roller includes a frame 1. A mounting base 4 is bolted to one side of the frame 1. A blade roller shaft 2 is rotatably mounted on the inner wall of the mounting base 4 via a bearing. A blade 3 is detachably mounted on the blade roller shaft 2. An annular groove 11 is provided on the frame 1. One end of the blade roller shaft 2 passes through the annular groove 11 and is fixedly mounted with a driven gear 8. A drive gear 9 is rotatably mounted on the frame 1.

[0041] When the folding machine is working normally, the passive gear 8 on the cutter roller shaft 2 meshes with the drive gear 9 on the frame 1. The drive gear 9 drives the passive gear 8 to rotate, which in turn drives the blade 3 to rotate at high speed through the cutter roller shaft 2.

[0042] When it is necessary to replace the blade 3 or adjust the clearance, after the equipment is stopped, first remove the bolts on the mounting base 4 to separate the mounting base 4 from the frame 1. Then, pull the cutter roller shaft 2 outward, causing it to move a certain distance within the annular groove 11. The driven gear 8 on the cutter roller shaft 2 disengages from the drive gear 9 on the frame 1. After the cutter roller shaft 2 moves to the maintenance position, the blade 3 on the cutter roller shaft 2 can be replaced or the clearance adjusted. When operating the blade 3, the cutter roller shaft 2 will slide left and right and rotate freely within the annular groove 11, unable to maintain a stable position. Since the cutter roller itself weighs several hundred kilograms, its shaking can easily cause injury to the operator's hands. Furthermore, when pushing the cutter roller shaft 2 within the annular groove 11, its free rotation can also easily cause injury to the operator's hands.

[0043] To this end, an auxiliary mechanism 5 is provided on the frame 1 to assist in the tool changing and adjustment work, so that the tool roller shaft 2 can remain stable when the operator changes or adjusts the tool, reducing the difficulty of operation and improving the safety factor of operation.

[0044] Specifically, the auxiliary mechanism 5 in this embodiment includes a support base 51, which is bolted to the frame 1 of the folding machine. A lead screw 52 is threaded onto the inner wall of the support base 51. A handle 54 is fixedly installed at one end of the lead screw 52 for manual control of its rotation. A clamping tooth 53 is rotatably installed at the other end of the lead screw 52. The clamping tooth 53 is arc-shaped, and its inner diameter is equal to the outer diameter of the cutter roller shaft 2, allowing it to partially enclose the cutter roller shaft 2. Both the clamping tooth 53 and the cutter roller shaft 2 have through holes. The two through holes overlap and are fixed by a connecting mechanism, allowing the clamping tooth 53 to drive the cutter roller shaft 2 to move.

[0045] It is worth noting that a rotation limit block 55 is fixedly connected to the end of the lead screw 52 away from the handle 54. The cross section of the rotation limit block 55 is convex, and the rotation limit block 55 is rotatably connected to the inner wall of the clamp 53. This is to prevent the lead screw 52 from disengaging from the clamp 53, and to ensure that the clamp 53 does not rotate with the lead screw 52 when the lead screw 52 rotates.

[0046] Preferably, a guide rod 10 is fixedly installed on the tooth 53. The surface of the guide rod 10 is slidably connected to the inner wall of the support base 51 to limit the rotation of the tooth 53, so that the tooth 53 can maintain its original angle after it is disengaged from the cutter roller shaft 2, thereby facilitating its docking with the cutter roller shaft 2.

[0047] During installation, the auxiliary mechanism 5 will hold the retaining tooth 53 as follows: Figure 1The vertical position shown allows the clamping tooth 53 to face the cutter roller shaft 2. Then, the bracket seat 51 is installed and fixed on the frame 1 of the folding machine with bolts, and it can be used immediately. The installation is convenient and quick, and will not interfere with the normal operation of the folding machine. It can be put into use quickly.

[0048] When in use, the auxiliary mechanism 5 first adjusts the angle of the cutter roller shaft 2 so that the through hole on the cutter roller shaft 2 coincides with the through hole on the clamping tooth 53. Then, the clamping tooth 53 is fixed to the cutter roller shaft 2 through the connecting mechanism to ensure that the cutter roller shaft 2 neither slides nor rotates in the annular groove 11. Then, the rotating handle 54 is rotated, which drives the lead screw 52 to rotate. Since the lead screw 52 is threadedly connected to the support base 51 and the support base 51 is fixed on the frame 1 of the folding machine and cannot rotate, the lead screw 52 will move along its own axis while rotating, and drive the clamping tooth 53 to move through the rotating limit block 55. The clamping tooth 53 drives the cutter roller shaft 2 to slide in the annular groove 11 through the connecting mechanism, thereby moving the cutter roller shaft 2 from the working position to the maintenance position.

[0049] Example 2

[0050] Based on Example 1, please refer to Figure 3 In this embodiment, the connecting mechanism is a limiting screw 6, and the through hole on the tooth 53 and the cutter roller shaft 2 is a threaded hole that matches the limiting screw 6. The limiting screw 6 and the threaded hole cooperate to fix the tooth 53 and the cutter roller shaft 2.

[0051] When installing or removing the clamping tooth 53, first ensure that the two through holes coincide, and then use tools such as wrenches or screwdrivers to apply torque to the limit screw 6 to achieve installation or removal.

[0052] Example 3

[0053] Based on Example 1, please refer to Figures 4-9 The difference between this embodiment and Embodiment 2 lies only in that the connecting mechanism includes a locking pin 71, which is inserted into a through hole on the tooth 53. A rectangular groove 711 is formed on the locking pin 71. A rectangular limiting block 72 is fixedly connected to the surface of the tooth 53, and the rectangular limiting block 72 is slidably connected to the inner wall of the rectangular groove 711 to limit the locking pin 71, preventing it from detaching from the tooth 53. A control component 73 is connected to the locking pin 71 to control its up-and-down movement, allowing it to enter or disengage from the cutter roller shaft 2.

[0054] Specifically, the control component 73 includes a rotating block 731, which is rotatably connected to a locking pin 71 via a connecting rod 732. A sliding rod 733 is fixedly connected to the rotating block 731, and a swing arm 735 is slidably connected to the surface of the sliding rod 733. A connecting spring 734 is sleeved on the outside of the sliding rod 733. One end of the connecting spring 734 is fixedly connected to the rotating block 731, and the other end is fixedly connected to the swing arm 735, which limits the range of motion of the swing arm 735 on the sliding rod 733 and drives the swing arm 735 to reset. The retaining tooth 53 has a movable groove 531 for the swing arm 735 to move.

[0055] One end of the swing arm 735 is fixedly connected to a drive shaft 736. The drive shaft 736 is rotatably mounted on the inner wall of the clamp 53. A drive gear 737 is fixedly mounted on the drive shaft 736. A drive rack 738 meshes with the surface of the drive gear 737. The drive rack 738 is slidably connected to the inner wall of the clamp 53. When the drive rack 738 moves horizontally, it can drive the drive gear 737 to rotate through meshing. The drive gear 737 drives the swing arm 735 to swing through the drive shaft 736. The swing arm 735 drives the rotating block 731 to swing through the sliding rod 733. At this time, the locking pin 71 will move up and down due to the restriction of the through hole.

[0056] To improve the stability between the clamping tooth 53 and the cutter roller shaft 2, two sets of through holes are provided, and two sets of structures such as the retaining pin 71, swing arm 735, drive shaft 736, drive rack 738, and drive gear 737 are also provided. One drive rack 738 meshes with the drive gear 737 from above, and the other drive rack 738 meshes with the drive gear 737 from below. This allows the two drive racks 738 to move synchronously, while the two drive gears 737 can rotate in opposite directions simultaneously. This, in turn, drives the two swing arms 735 to swing in opposite directions via the two drive shafts 736.

[0057] The control assembly 73 also includes a sliding plate 739, which is slidably mounted on the inner wall of the tooth 53. One end of the sliding plate 739 is fixedly connected to two transmission racks 738, so that when the sliding plate 739 moves, it can simultaneously drive the two transmission racks 738 to move. The other end of the sliding plate 739 is fixedly connected to a control rod 7310, the surface of which is rotatably connected to the inner wall of the lead screw 52. The end of the control rod 7310 away from the sliding plate 739 passes through the lead screw 52 and the handle 54 and is fixedly connected to a control button 7312. Pressing the control button 7312 provides power for the operation of the control assembly 73. A return spring 7311 is sleeved on the outside of the control rod 7310. One end of the return spring 7311 is fixedly connected to the inner wall of the tooth 53, and the other end is fixedly connected to the sliding plate 739, so that the sliding plate 739 can automatically return to its original position when the external force restriction is lost.

[0058] Furthermore, the surface of the sliding plate 739 is provided with a recessed portion, and the inner wall of the clamping tooth 53 is provided with a protrusion. The recessed portion can slide on the protrusion. The two cooperate with each other to restrict the relative rotation between the sliding plate 739 and the clamping tooth 53, so that the control lever 7310 will not rotate with the rotation of the lead screw 52.

[0059] In this embodiment, the connecting mechanism is used by first pressing the control button 7312 towards the lead screw 52. The control button 7312 drives the control rod 7310 to slide within the lead screw 52. The control rod 7310 pushes the sliding plate 739 to one side, stretching the return spring 7311. As the sliding plate 739 moves, it simultaneously drives the two transmission racks 738 to move. The two transmission racks 738 mesh with each other, driving the two transmission gears 737 to rotate in opposite directions. The two transmission gears 737, respectively, drive the two swing arms 735 to swing through the two transmission shafts 736, causing the two swing arms 735 to be in an outward "open" state. The swing arms 735 drive the rotating block 731 to swing through the sliding rod 733, thereby applying an external force to the locking pin 71 through the connecting rod 732. Since the locking pin 71 cannot rotate due to the restriction of the through hole, the rotating block 731 will rotate relative to the locking pin 71, and the sliding rod 733 will slide relative to the swing arm 735 to avoid motion interference. At this time, the two locking pins 71 will move outward from the tooth 53 at the same time.

[0060] Then, rotating the handle 54 causes the lead screw 52 to rotate, creating a helical transmission between the lead screw 52 and the support base 51. As the lead screw 52 rotates, it moves towards the cutter roller shaft 2, causing the clamping tooth 53 to move as well, until the inner circumference of the clamping tooth 53 is fully engaged with the outer circumference of the cutter roller shaft 2. At this point, the control button 7312 can be released. If the through hole on the cutter roller shaft 2 coincides with the through hole on the clamping tooth 53 after the control button 7312 is released, the connecting mechanism will automatically reset under the elastic force of the connecting spring 734 and the return spring 7311, and the locking pin 71 will automatically engage in the through hole on the cutter roller shaft 2. If the through hole on the cutter roller shaft 2 does not coincide with the through hole on the clamping tooth 53 after the control button 7312 is released, the angle of the cutter roller shaft 2 should be adjusted. When the through holes coincide, the locking pin 71 will automatically engage in the cutter roller shaft 2, thus limiting the movement of the cutter roller shaft 2.

[0061] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
