Description

Technical Field

[0001] This utility model relates to the field of carding machine tools, specifically a carding machine roller assembly / disassembly tool. Background Technology

[0002] Existing roller disassembly methods typically involve threading a flange ring onto the drive shaft, as the roller is fixed to the drive shaft. The roller body has evenly distributed threaded holes, and the flange ring also has threaded holes corresponding to the number of threaded holes on the roller body. During disassembly, the threaded holes on the flange ring are aligned with the threaded holes on the roller body. A screw is then inserted through the flange ring's hole and into the threaded hole on the roller body. A wrench is used to continuously screw the screw in until the nut on the screw contacts the flange ring. This process continues until the roller is finally separated from the drive shaft. While current carding machine roller assembly / disassembly devices can assemble and disassemble carding machine rollers, their main force-applying rods are quite long, taking up considerable space for storage and making them inconvenient to carry. Furthermore, during the rotation of the workpiece, the length of the main force-applying rod cannot be extended, preventing an increase in the length of the drive arm. Therefore, their practicality needs improvement. Utility Model Content

[0003] The purpose of this utility model is to provide a carding machine roller mounting and dismounting device to solve the problems mentioned in the background art. Although the current carding machine roller mounting and dismounting device can mount and dismount the carding machine roller, its main force rod is too long, which takes up a lot of space for storage and is inconvenient to carry. At the same time, during the rotation of the workpiece, the length of the main force rod cannot be extended, and the length of the active arm cannot be increased, so the practical performance needs to be improved.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a carding machine roller mounting and dismounting device, including a slot frame, a clamping block provided on the right side of the slot frame, a slider fixedly connected to the left surface of the clamping block, the slider being slidably engaged with the slot frame through a sliding groove, a screw being rotatably connected to the center of the upper surface of the clamping block, the screw being threadedly connected to the through surface of the slot frame, and a force-applying rod provided on the upper part of the outer wall of the screw;

[0005] The force-applying rods include a vertical cylinder, a vertical groove, a support block, a lead screw, a round block, a ring, a protrusion, a support rod, and a magnetic block;

[0006] The vertical cylinder is sleeved on the upper part of the outer wall of the screw. Vertical grooves are opened on both the left and right sides of the inner wall of the vertical cylinder. A support block is slidably engaged inside the vertical groove. The support block is fixedly connected to the contact surface of the screw. A lead screw is vertically provided at the top of the inner wall of the vertical cylinder. The lead screw is internally threaded to the screw. A round block is rotatably connected to the top of the outer wall of the lead screw. The round block is fixedly connected to the contact surface of the vertical cylinder. A ring is fixedly connected to the top of the lead screw. Protrusions are fixedly connected to both the left and right ends of the round block. A support rod is hinged to the right side of the protrusion. Magnetic blocks are fixedly connected to the top of both the left and right sides of the outer wall of the round block.

[0007] Preferably, the two support rods are symmetrical about the center point of the circular block.

[0008] Preferably, the outer wall of the vertical cylinder is textured.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This carding machine roller mounting and dismounting device has the following advantages over traditional technology:

[0010] By utilizing the coordination between the slotted frame, clamping block, slider, slide groove, screw, and force-applying rod, the rollers of a carding machine are assembled and disassembled. First, the workpiece to be stressed on the roller is placed between the clamping block and the slotted frame. Then, the support rod is rotated outwards, allowing force to be applied to it, causing the circular block, vertical cylinder, and screw to rotate clockwise. The clamping block and slotted frame clamp the workpiece to be stressed on the roller. Next, force is applied to the ring to rotate the lead screw, causing the lead screw, vertical cylinder, and circular block to move upwards. This increases the length of the active arm required to rotate the clamping block and slotted frame, making it easier for the operator to rotate and apply force to the workpiece on the roller. After applying force, force is applied to the support rod to separate the clamping block and slotted frame from the workpiece on the roller. Then, the ring can be rotated in the opposite direction, causing the vertical cylinder to move downwards towards the outer wall of the screw. Finally, the support rod is rotated inwards, causing the magnetic block to attract the support rod. This reduces the overall space occupied by the assembly / disassembly device, making it easier for users to carry and enhancing its practicality. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a carding machine roller mounting / removing device, including a slot frame 1, a clamping block 2 on the right side of the slot frame 1, a slider 3 fixedly connected to the left surface of the clamping block 2, the slider 3 being slidably connected to the slot frame 1 through a sliding groove 4, the slider 3 being able to slide up and down inside the sliding groove 4, but not being able to move back and forth, which can enhance the stability of the clamping block 2 when moving up and down, a screw 5 being rotatably connected to the center of the upper surface of the clamping block 2, the screw 5 being rotatably connected to the clamping block 2 through a ball bearing, the screw 5 being threadedly connected to the through surface of the slot frame 1, and a force-applying rod being provided on the upper part of the outer wall of the screw 5. Component 6, the force-applying component 6 includes a vertical cylinder 601, a vertical groove 602, a support block 603, a lead screw 604, a round block 605, a ring 606, a protrusion 607, a support rod 608, and a magnetic block 609. The vertical cylinder 601 is sleeved on the upper part of the outer wall of the lead screw 5. The inner wall of the vertical cylinder 601 is clearance-fitted with the outer wall of the lead screw 5. Vertical grooves 602 are vertically opened on both the left and right sides of the inner wall of the vertical cylinder 601. The support block 603 is slidably engaged inside the vertical groove 602. The support block 603 can slide up and down inside the vertical groove 602, but cannot move forward, backward, left, or right. A lead screw 604 is vertically mounted on the top of the inner wall of the vertical cylinder 601, and its outer wall is clearance-fitted with the through surface of the vertical cylinder 601. The lead screw 604 is internally threaded to the lead screw 5. The thread friction between the lead screw 604 and the lead screw 5 is less than the thread friction between the lead screw 5 and the slot frame 1, meaning the lead screw 5 will not rotate during the rotation of the lead screw 604. A round block 605 is rotatably connected to the top of the outer wall of the lead screw 604. The lead screw 604 is rotatably connected to the round block 605 via a ball bearing. The round block 605 is connected to the vertical cylinder 601... The contact surfaces are fixedly connected. A ring 606 is fixedly connected to the top of the lead screw 604. A protrusion 607 is fixedly connected to both ends of the round block 606. A support rod 608 is hinged to the right side of the protrusion 607. Magnetic blocks 609 are fixedly connected to the top of both sides of the outer wall of the round block 605. The two support rods 608 are symmetrical about the center point of the round block 605, so that the two support rods 608 can apply force evenly to the round block 605 after being subjected to force. The outer wall of the vertical cylinder 601 is processed with a textured surface 7. The textured surface 7 can enhance the friction of the outer wall of the vertical cylinder 601, making it easier for the operator to apply force to the vertical cylinder 601.

[0018] When using a carding machine roller assembly / disassembly tool to assemble or disassemble the carding machine rollers, first place the workpiece to be stressed between the clamping block 2 and the slot frame 1. Then, rotate the support rod 608 outwards to extend it. At this point, force can be applied to the support rod 608, causing the circular block 605, the vertical cylinder 601, and the screw 5 to rotate clockwise. The clamping block 2 and the slot frame 1 can clamp the workpiece to be stressed on the roller. Then, force is applied to the ring 606 to rotate the lead screw 604. Due to the threaded connection between the lead screw 604 and the screw 5, and the sliding limit relationship between the vertical slot 602 and the support block 603, the lead screw 604 and the vertical slot 602 can rotate clockwise. Both cylinder 601 and circular block 605 move upward, which increases the length of the active arm required to rotate clamping block 2 and slot frame 1, making it easier for the operator to rotate and apply force to the workpiece to be forceped by the roller. After the force is applied, force is applied to support rod 608, causing clamping block 2 and slot frame 1 to separate from the workpiece by the roller. At this time, the ring 606 can be rotated in the opposite direction, causing vertical cylinder 601 to move downward above the outer wall of screw 5. Then, support rod 608 is rotated inward, causing magnetic block 609 to attract support rod 608. This reduces the overall space occupied by the assembly / disassembly device, making it easier for users to carry and enhancing its practicality.
