Description

Technical Field

[0001] This invention relates to the field of cat climbing column production technology, and more particularly to a pneumatic traction device for a rope winding machine. Background Technology

[0002] Cat climbing posts are a popular pet accessory loved by cats. They typically have a sturdy main post, usually made of wood or durable plastic, and come in various heights. The post has multiple platforms of different shapes and sizes for cats to rest on. Some cat climbing posts also include a cat bed or hammock. The outer layer of the post is often wrapped with sisal rope. Sisal is rough and durable, allowing cats to sharpen their claws while also attracting them to climb and play. This satisfies cats' active nature, their love of scratching, and their desire to stay in high places. It is a multi-functional item that provides cats with entertainment and rest. During the production of cat climbing posts, the sisal rope is usually wound quickly using a cat climbing post rope winding machine.

[0003] Currently, existing cat-climbing column rope winding machines do not have a traction device for the hemp rope. When winding the hemp rope, the operator usually pulls the hemp rope taut by hand to control it to wind around the column. However, since it is difficult for the manual walking speed to keep up with the feeding speed during rope winding, the gaps between the hemp ropes are inconsistent and relatively loose, resulting in low quality of cat-climbing column. At the same time, manual operation leads to low production efficiency. Therefore, a pneumatic traction device for the rope winding machine was designed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pneumatic traction device for a rope winding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pneumatic traction device for a rope winding machine includes a side plate. A lower wheel axle is fixedly connected to the side plate near the bottom by a nut. A circular hole adapted to the lower wheel axle is opened at the bottom of the side plate. A limiting sleeve that mates with a bolt is fixedly connected to one end of the lower wheel axle near the side plate. A circular baffle is fixedly connected to the other end of the lower wheel axle away from the side plate. A connecting rod is provided at the other end of the lower wheel axle away from the side plate, and an adjustment mechanism is provided on the circumferential surface of the connecting rod. The adjustment mechanism includes a fixed plate fixedly connected to the end of the connecting rod near the circular baffle. L-shaped plates are fixedly connected to the top and bottom of the end of the fixed plate away from the lower wheel axle. Sliding rods are slidably mounted on both L-shaped plates. Circular holes adapted to the sliding rods are opened on both L-shaped plates. The same second disc is fixedly connected to the end of the two sliding rods near the lower wheel axle. Multiple second protrusions are evenly arranged on the circumference of the side of the second disc near the lower wheel axle. The other end of the two sliding rods is fixedly connected to a first strong magnet through a mounting base.

[0006] As a further embodiment of the present invention, the adjusting mechanism further includes a rotating lead screw sleeve rotatably sleeved on the circumferential surface of the connecting rod away from the lower wheel axle. An adjusting knob is fixedly connected to the outer end of the rotating lead screw sleeve away from the fixed disc. A screw block is screwed onto the circumferential surface of the rotating lead screw sleeve. A lead screw nut adapted to the rotating lead screw sleeve is fixedly sleeved in the middle of the screw block. A cover plate is fixedly connected to the side of the screw block away from the fixed disc. Two guide rods are fixedly connected to the end of the fixed disc near the screw block, and both guide rods penetrate the screw block and the cover plate.

A limiting rack is also fixedly connected to the side of the fixing plate near the screw block, and the limiting rack passes through the screw block and the cover plate. Square holes that fit the limiting rack are provided on both the screw block and the cover plate. The position of the screw block can be precisely adjusted by rotating the screw sleeve through the adjustment knob. An installation cavity is provided inside the screw block, and a limiting mechanism is provided inside the installation cavity. The limiting mechanism ensures that the user can only rotate the adjustment knob after pressing the button.

[0007] As a further embodiment of the present invention, the limiting mechanism includes a rectangular frame slidably connected to the inner side of the screw block, and the rectangular frame is in contact with the top and bottom of the mounting cavity. The rectangular frame has a toothed groove adapted to the limiting rack on the side near the limiting rack, and two arc-shaped spring pieces are fixedly connected to the side of the mounting cavity away from the limiting rack, and the other ends of the two arc-shaped spring pieces are in contact with the rectangular frame. A push block is fixedly connected to the outer side of the rectangular frame away from the limiting rack, and a circular hole adapted to the push block is opened on the outer side of the screw block. A protrusion is fixedly connected to the top and bottom of the screw block, and a second strong magnet is embedded in each protrusion. The two second strong magnets have the same magnetism on the side close to the first strong magnet. By controlling the position of the second strong magnet, the squeezing force of the second disc on the first disc is different, thereby controlling the rotation speed of the concave wheel.

[0008] As a further embodiment of the present invention, a square sleeve is fitted on the side of the circular baffle away from the side plate of the lower wheel axle. A lower bearing is fixedly fitted on the inner side of the square sleeve, and the inner circumference of the lower bearing is adapted to the circumferential surface of the lower wheel axle. A concave wheel is fitted on the outer side of the square sleeve. A first disc is fixedly connected on the side of the square sleeve away from the circular baffle, and a plurality of first protrusions are fixedly connected at equal intervals on the circumference of the side of the first disc close to the second disc. The arrangement of the square sleeve, the first disc, and the first protrusions, etc., and the concave wheel, etc., facilitates disassembly. At the same time, the rotation of the concave wheel will cause the first disc and other components to rotate accordingly.

[0009] As a further embodiment of the present invention, a rectangular hole is provided in the middle of the connecting rod, and a buckling mechanism is provided in the rectangular hole. The buckling mechanism includes a square rod fixedly connected between the two sides of the middle of the rectangular hole. L-shaped clips are slidably sleeved at both ends of the square rod. A square hole adapted to the square rod is provided in the middle of the two L-shaped clips. A spring is sleeved on the square rod at the middle of the two L-shaped clips. A fixing plate is fixedly connected to the side of the middle of the two L-shaped clips that is close to each other, and the two fixing plates are staggered. An oblique hole is provided on both fixing plates. The same U-shaped rod is slidably connected to the inner side of the two oblique holes. An installation button is fixedly connected to the end of the U-shaped rod away from the lower wheel axle, and the installation button is slidably connected in the rectangular hole. The buckling mechanism facilitates the user to disassemble the connecting rod and replace and maintain the lower concave wheel.

[0010] As a further embodiment of the present invention, a T-shaped groove is provided at one end of the lower wheel axle near the connecting round rod, and the T-shaped groove is adapted to two L-shaped clips.

[0011] As a further embodiment of the present invention, an upper top plate is fixedly connected to the top of the side plate by bolts, and a pressing cylinder is fixedly connected to the middle position of the top of the upper top plate. The pressing cylinder is connected to an air pump through a pressure reducing valve. A pneumatic connecting plate is fixedly connected to the bottom output end of the pressing cylinder through the upper top plate. Fixed guide posts are fixedly connected to both ends of the bottom of the pneumatic connecting plate by bolts. The bottom of the two fixed guide posts is rotatably connected to the same upper wheel shaft. An upper cam is rotatably connected to the middle of the upper wheel shaft through an upper bearing.

[0012] As a further embodiment of the present invention, a mounting plate is fixedly connected to the bottom of the upper top plate away from the side plate by bolts. Two guide post fixing plates are fixedly connected to the side of the mounting plate and the side plate that are close to each other. The two guide post fixing plates on the same side are located on both sides of the fixed guide post. The multiple guide post fixing plates can limit the fixed guide post to ensure the stability of the upper cam when it descends and does not deviate.

[0013] The beneficial effects of this invention are as follows: This invention employs an adjustment mechanism, a concave wheel, and a pneumatic connecting plate. The device moves with the following frame, using a concave cam to apply appropriate pressure to the hemp rope to achieve traction. Simultaneously, the adjustment mechanism allows for adjustment of the screw block's position by rotating the adjustment knob after pressing the actuating block. This, in conjunction with the first and second strong magnets, controls the squeezing force of the second disc on the first disc, adjusting the resistance of the concave wheel as the hemp rope rotates, thereby adjusting the rope tension. This effectively solves the problems of low efficiency and quality associated with manual operation mentioned in the prior art. It achieves rapid adjustment of the concave wheel's rotational resistance, precisely controlling the rope tension and position, resulting in uniform and tight rope winding, improving product quality and production efficiency, and enhancing the automation level of the equipment.

Two guide rods 608 are fixedly connected to the end of the fixed disk 601 near the screw block 611. Both guide rods 608 pass through the screw block 611 and the cover plate 614. Both the screw block 611 and the cover plate 614 have round holes that match the two guide rods 608. The other end of each guide rod 608 is fixedly connected to a protrusion. The fixed plate 601 is also fixedly connected to a limiting rack 610 on the side near the screw block 611. The limiting rack 610 passes through the screw block 611 and the cover plate 614. Both the screw block 611 and the cover plate 614 have square holes that match the limiting rack 610. The screw block 611 has an installation cavity on its inner side, and a limiting mechanism is provided inside the installation cavity.

The top and bottom of the screw block 611 are fixedly connected to protrusions 612. Each protrusion 612 is embedded with a second strong magnet 613. The two second strong magnets 613 have the same magnetism on the side that is close to the first strong magnet 609. The cooperation between the second strong magnet 613 and the first strong magnet 609 makes the second strong magnet 613 closer to the first strong magnet 609, the greater the force of the second disc 604 pressing the first disc 502, and the greater the force, the less the force, as they are further apart.

[0022] In this embodiment, a square sleeve 501 is fitted on the side of the circular baffle 302 away from the side plate 1. A lower bearing 504 is fixedly fitted inside the square sleeve 501, and the inner circumference of the lower bearing 504 is adapted to the circumferential surface of the lower sleeve 3. A concave wheel 5 is fitted on the outer side of the square sleeve 501. A first disc 502 is fixedly connected to the side of the square sleeve 501 away from the circular baffle 302, and multiple first protrusions 503 are fixedly connected at equal intervals on the circumference of the side of the first disc 502 close to the second disc 604. The arrangement of the square sleeve 501, the first disc 502, etc., allows the concave wheel 5 to drive the first disc 502 to rotate when it rotates. The adjusting mechanism 6 can control the rotational resistance of the concave wheel 5 by acting on the first disc 502, which facilitates the adjustment of the tension of the hemp rope.

[0023] In this embodiment, a rectangular hole 401 is provided in the middle of the connecting round rod 4, and a buckling mechanism 7 is provided in the rectangular hole 401. The buckling mechanism 7 includes a square rod 701 fixedly connected between the two sides of the middle of the rectangular hole 401.

[0024] In this embodiment, a T-shaped slot 303 is provided at one end of the lower wheel axle 3 near the connecting round rod 4, and the T-shaped slot 303 is adapted to two L-shaped clips 702.

[0025] In this embodiment, the top of the side plate 1 is fixedly connected to the top plate 2 by bolts. The middle position of the top of the top plate 2 is fixedly connected to the pressing cylinder 202. The pressing cylinder 202 is connected to the air pump through the pressure reducing valve. The bottom output end of the pressing cylinder 202 passes through the top plate 2 and is fixedly connected to the pneumatic connecting plate 8. Both ends of the bottom of the pneumatic connecting plate 8 are fixedly connected to the fixed guide post 801 by bolts. The bottom of the two fixed guide posts 801 are rotatably connected to the same upper wheel shaft. The middle of the upper wheel shaft is rotatably connected to the upper cam 802 through the upper bearing. Through the cooperation of the upper cam 802 and the lower concave wheel 5, pressure is applied to the hemp rope, so that the hemp rope is in a taut state when it is wrapped around the cat climbing post.

[0026] In this embodiment, the bottom of the top plate 2, away from the side plate 1, is fixedly connected to a mounting plate 201 by bolts. Two guide post fixing plates 203 are fixedly connected to the side of the mounting plate 201 and the side plate 1 that are close to each other. The two guide post fixing plates 203 on the same side are located on both sides of the fixed guide post 801. By setting four guide post fixing plates 203, the fixed guide post 801 is limited, so that when the upper cam 802 descends, it can be locked in the groove of the square sleeve 501.

[0027] Working principle: During the production of the cat-climbing column, this device is installed on the fixed following frame of the cat-climbing column rope winding machine. Before the hemp rope is wound around the cat-climbing column, it is first caught in the groove on the outer surface of the lower concave wheel 5. Then, the clamping cylinder 202 is activated, causing the upper cam 802 to descend. The protrusion on the circumference of the upper cam 802 can be caught in the groove of the square sleeve 501, thus squeezing the hemp rope and limiting the rope's output speed. This makes the position between the hemp rope and the cat-climbing column tight, resulting in a uniform and consistent gap when the hemp rope is wound around the cat-climbing column. Simultaneously, the adjustment mechanism 6... The adjustable concave wheel 5 has adjustable rotational friction. When the rotational speed of the concave wheel 5 needs to be adjusted, press the actuating block 616 to move the rectangular frame 615 and compress the arc-shaped spring 618. At this time, the retaining groove 617 will separate from the limiting rack 610. Then the user can turn the adjusting knob 607 to rotate the rotating lead screw sleeve 606, which will make fine adjustments with the screw block 611. At the same time, the distance between the second strong magnet 613 and the first strong magnet 609 is controlled, thereby controlling the squeezing force of the second disc 604 on the first disc 502. Through the interaction of the second convex strip 605 and the first convex strip 503, the actual... The rotational resistance of the concave wheel 5 is adjusted to adjust the tension of the hemp rope. After releasing the push block 616, the locking groove 617 engages with the limiting rack 610. At this time, rotating the adjustment knob 607 will prevent the screw block 611 from moving, ensuring that the device will not loosen during operation. When the thickness of the hemp rope needs to be changed and the concave wheel 5 needs to be replaced, press the installation button 707 of the buckle mechanism 7. Through the action of the U-shaped rod 706 and the two oblique holes 705, the two L-shaped locking strips 702 are brought closer together. At this time, the connecting round rod 4 can be disassembled along with the entire adjustment mechanism 6, and then the square sleeve can be removed. Pull out the cylinder 501, replace it with a new concave wheel 5, put it on the outside of the square sleeve 501, and reset the device. This allows for quick replacement of the concave wheel 5. When the concave wheel 5 rotates under the action of the hemp rope, the square sleeve 501 and the first disc 502 also rotate. If the upper cam 802 needs to be replaced, it can be replaced by removing the mounting plate 201. This achieves uniform and beautiful winding of the cat climbing column, reducing the intensity of manual labor. Originally, it took about 20 seconds to manually pull each winding column, and the yield was not high. After adding this device, one winding column is wound every 11 seconds, and the yield is greatly improved.
