Description
Technical Field
[0001] This utility model belongs to the field of rope winding machines, and specifically relates to a bending tube rope winding device. Background Technology
[0002] A cat scratching post (also known as a cat climbing post) is a pet product with rope (usually hemp rope) wrapped around the surface of a round tube / cylinder. Cats can use their paws to grab the rope on the surface of the scratching post, which can sharpen their claws and allow them to climb and exercise, satisfying their instinctive needs.
[0003] Traditional cat scratching posts rely on manual rope winding, which is inefficient and prone to loosening due to the instability of manual operation. To address this issue, those skilled in the art have developed rope winding machines. For example, the technical solution published by the Chinese Patent Office on October 29, 2019, with publication number CN209546584U, entitled "A Rope Winding Machine for Cat Climbing Frames," includes a frame and a drive mechanism capable of laterally fixing and rotating a cylindrical material. A mounting plate that can move laterally is longitudinally located in the middle of the frame. One end of the mounting plate has a pressing mechanism that presses the rope against the outer surface of the cylindrical material, and the other end has an adhesive applicator that applies glue to the winding surface of the rope. This pressing mechanism design makes the rope winding more stable, resulting in better stability and higher quality after winding.
[0004] However, the above-mentioned rope winding machine still has shortcomings in use:
[0005] Its pressing mechanism uses a pressure plate with a flat lower surface, which is only suitable for use with straight cat scratching posts. With the development of pet products, curved cat scratching posts have now appeared. When the above-mentioned rope winding machine is used to wind curved cat scratching posts, because the cat scratching posts themselves are curved, the pressure plate cannot press the rope against the surface of the post at all times when rotating, resulting in poor quality of rope winding on the surface of the post. Utility Model Content
[0006] The purpose of this utility model is to provide a pipe bending rope winding device, which is equipped with an arc-shaped pressure plate and a rope pressing head, and works in conjunction with a tensioning cylinder and a platform that moves back and forth, so that the arc-shaped pressure plate and the rope pressing head always press the rope tightly on the surface of the pipe / column, thereby improving the rope winding quality.
[0007] This utility model is achieved through the following technical solution:
[0008] A rope-winding device for bending pipes includes a frame, a drive motor at one end of the frame, and a drive motor connected to a drive mounting plate. The device is characterized by a rope-winding and pressing mechanism located at the rear of the frame. This mechanism includes a transversely moving base, two parallel transverse sliding rods mounted on the frame below the base, two sliding rod sliders fitted onto the transverse sliding rods at the bottom of the base, and a longitudinal slide rail perpendicular to the sliding rods located at the upper center of the base. The transversely moving base also has a longitudinally moving... The base is a longitudinally movable base that is slidably mounted on a longitudinal slide rail. A vertical column is provided on the longitudinally movable base, and a swing arm is hinged to the upper end of the vertical column. An arc-shaped pressure plate and a handle are respectively provided on both sides of the front end of the swing arm. A pressure plate central column is provided in the middle of the arc-shaped pressure plate, and the pressure plate central column is hinged to the swing arm through a central axis. A pressure rope head is provided on the inner side of the arc-shaped pressure plate. A pressure plate cylinder is also provided on the side of the longitudinally movable base. The lower end of the cylinder body of the pressure plate cylinder is hinged to the longitudinally movable base, and the upper end of the piston rod of the pressure plate cylinder is hinged to the swing arm.
[0009] The arc-shaped pressure plate of this utility model is preferably a semi-circular pressure plate, whose inner diameter matches the outer diameter of the bent pipe / bent column to be wound with rope.
[0010] The most significant characteristic of bending pipes / columns during rope winding is that the radius of rotation of the bending pipe / column varies. Traditional pressure plates, unable to move back and forth or up and down, cannot always remain in contact with the surface of the bending pipe / column. This invention uses a longitudinally movable base that can move back and forth, combined with a swing arm and pressure plate cylinder that can swing up and down, allowing the arc-shaped pressure plate to always remain in contact with the surface of the bending pipe / column. The rope-pressing head on one side of the pressure plate keeps the rope pressed against the surface of the bending pipe / column, improving the quality of rope winding.
[0011] Furthermore, the arc-shaped pressure plate of this utility model is provided with a pressure plate side rod on each side of the central column of the pressure plate, and the two pressure plate side rods are connected to the central shaft by a tension spring.
[0012] The arc-shaped pressure plate is hinged to the swing arm via the central axis. It can rotate around the central axis, allowing it to better fit the surface of the bent pipe / column. Two tension springs pull the arc-shaped pressure plate from the left and right, enabling it to reset after rotation.
[0013] Furthermore, the pressure plate column of this utility model is preferably a hollow cylindrical structure, with a pressure plate stud provided at the upper middle part of the arc-shaped pressure plate, the pressure plate stud passing through the pressure plate column, and a pressure plate fixing nut provided at the upper end of the pressure plate stud.
[0014] Unscrew the pressure plate studs and remove the two tension springs to separate the arc-shaped pressure plate from the pressure plate column. In other words, the arc-shaped pressure plate and the pressure plate column of this utility model are detachable structures, and different sizes of arc-shaped pressure plates can be replaced to adapt to bends / columns of different diameters.
[0015] Furthermore, the rope pressing head of this utility model is installed on the rope pressing adjustment mechanism, which includes a screw, a screw sleeve and an adjusting nut. The screw sleeve is fixed to the inside of the pressure plate side rod. The screw sleeve has openings at the top and bottom and is provided with internal threads. The screw is installed inside the screw sleeve, and its lower end is connected to the rope pressing head. Adjusting nuts are provided at both the top and bottom ends of the screw sleeve and are installed on the screw.
[0016] The vertical position of the rope-pressing head can be adjusted using the rope-pressing adjustment mechanism to adapt to different ropes and improve the rope-winding effect.
[0017] Furthermore, the frame at the end where the drive motor is installed in this utility model is equipped with a pulley, one end of the pull rope is connected to the transverse moving base, and the other end passes around the pulley and is connected to the counterweight.
[0018] When the rope is wound, the lateral moving base will slide along the lateral slide bar away from the drive motor. After the rope is wound, the cat climbing column is removed. Under the action of the counterweight and the pull rope, the lateral moving base will return to its initial position and wait for the next rope winding operation.
[0019] Furthermore, the longitudinally moving base of this utility model has a forward-extending connecting plate at its front end, and a straightening mechanism is installed at the front end of the connecting plate. The straightening mechanism includes a rope pulling mechanism base perpendicular to the connecting plate. The front side of the rope pulling mechanism base has two upper and lower rope winding pulleys. The lower end of the rope pulling mechanism base has an outward-sloping inclined plate. The middle of the lower end of the inclined plate has a rope threading tube. The inclined plate also has a rope pressing frame. The rope pressing frame includes two side rods. The front ends of the two side rods are connected by a rope pressing shaft. The rear ends of the two side rods of the rope pressing frame are bolted to both sides of the inclined plate.
[0020] For ease of transportation and storage, the rope used for winding is generally wound up. Winding will cause the rope to bend. Straightening the rope before winding helps to improve the quality of winding. The rope is passed through the rope tube, then around the rope pressing shaft of the rope pressing frame from below, and then around two winding pulleys in sequence, which straightens the coiled rope.
[0021] The rope pressing frame of this utility model allows for adjustment of the gap between the rope pressing shaft and the inclined plate after loosening the bolts. Once the gap is adjusted, the bolts can be tightened.
[0022] Furthermore, the drive mounting plate of this utility model has three threaded mounting holes that are evenly distributed around its circumference.
[0023] The drive mounting plate of this utility model is connected to the arc-shaped cat climbing column by bolts, and preferably has 3 threaded mounting holes.
[0024] This invention has the advantages of reasonable structure and flexible and convenient use. Using this invention can improve the rope winding efficiency and quality of curved cat climbing posts. Attached Figure Description

The lower end of the cylinder body of the pressure plate cylinder 26 is hinged to the longitudinal movable base 9. The upper end of the piston rod of the pressure plate cylinder 26 is hinged to the swing arm 12. The middle part of the arc-shaped pressure plate 18 is provided with a pressure plate central column 13. The pressure plate central column 13 is connected to the central shaft 29. The swing arm 12 is hinged, and the pressure plate column 13 is a hollow cylindrical structure. A pressure plate stud 27 is located at the upper center of the arc-shaped pressure plate 18, passing through the pressure plate column 13. A pressure plate fixing nut 28 is located at the upper end of the pressure plate stud 27. A pressure plate side rod 15 is also located on each side of the pressure plate column 13 on the arc-shaped pressure plate 18. The two pressure plate side rods 15 are connected to the central shaft via a tension spring 14. A rope-pressing head 17 is located on the inner front side of the arc-shaped pressure plate 18. The rope-pressing head 17 is mounted on a rope-pressing adjustment mechanism. The screw sleeve 32 of the rope-pressing adjustment mechanism is fixed to the front pressure plate side rod 15. The screw sleeve 32 has openings at the top and bottom and internal threads. The screw 30 is installed inside the screw sleeve 32, and its lower end is connected to the rope-pressing head 17. The connection includes adjusting nuts 31 installed on the screw 30 at both ends of the screw sleeve 32, and a forward-extending connecting plate 21 at the front end of the longitudinal moving base 8. A straightening mechanism is installed at the front end of the connecting plate 21. The straightening mechanism includes a rope pulling mechanism base 25 perpendicular to the connecting plate 21. The front side of the rope pulling mechanism base 25 is provided with two rope winding pulleys 20. The lower end of the rope pulling mechanism base 25 is provided with an outward-sloping inclined plate 22. A rope threading tube 23 is provided in the middle of the lower end of the inclined plate 22. A rope pressing frame 24 is also provided on the inclined plate 22. The rope pressing frame 24 includes two side rods. The front ends of the two side rods are connected by a rope pressing shaft. The rear ends of the two side rods of the rope pressing frame 24 are bolted to both sides of the inclined plate 22.
[0031] like Figure 3As shown: The bottom of the bent tube 33 to be wound is provided with a bent tube base 34, and the bottom surface of the bent tube base 34 is provided with bent tube base bolt holes 35 that match the threaded mounting holes on the drive mounting plate 7.
[0032] In use, align the bolt holes 35 of the bend base 34 with the threaded mounting holes on the drive mounting plate 7, and then connect them together with bolts. First, apply glue to the surface of the bend 33, then attach one end of the bottom fabric strip to the left end of the bend 33. Start the drive motor 6 and wrap the bottom fabric strip around the surface of the bend 33. After wrapping, turn off the drive motor 6, cut the bottom fabric strip, and manually apply glue to the end of the strip. Attach it to the right end of the bend 33, start the drive motor 6, and use a brush to apply glue to the bend 33. Apply adhesive to the surface of the bottom fabric strip. After applying the adhesive, turn off the drive motor 6. Unwind the rope from the unwinding mechanism, pass the rope end through the rope tube 23, and then pass it around the rope pressing shaft of the rope pressing frame 24 from below. Then, pass it around the two rope winding pulleys 20 in sequence and stick the rope end to the left end of the bend tube 33. Start the drive motor 6, and the bend tube 34 will rotate, causing the rope to wrap around the bend tube 34 1-2 times. Turn off the drive motor 6, hold the handle 16, move the lateral moving base 8 left and right, and move the longitudinal moving base 9 forward and backward, pressing down the arc-shaped pressure plate 18. Make it fit against the rope winding point of the bend 33, so that the rope pressing head 17 presses down on the rope. Release the handle 16, start the pressure plate cylinder 26, so that it is in the piston rod retracted state, start the drive motor 6, and continuously wind the rope on the surface of the bend 33. During the winding process, the lateral moving base 8 automatically moves to the right along the lateral slide bar 19. When the bend 33 rotates, the longitudinal moving base 9, which can move back and forth, the swing arm 12, which can swing up and down, the pressure plate cylinder 26, and the two tension springs 14 ensure that the arc-shaped pressure plate 18 is always in contact and pressed tightly. On the surface of the bend 33, ensure that the rope pressing head 17 keeps the rope pressed tightly against the surface of the bend 33 at all times. When the rope is wound close to the right end of the bend 33, turn off the drive motor 6, control the pressure plate cylinder 26 to extend its piston rod, lift the swing arm 12 upward, so that the arc-shaped pressure plate 18 separates from the bend 33. Under the action of the counterweight 3 and the pull rope 4, the lateral moving base 8 returns to the initial position at the left end of the frame 2. The rope is cut manually, thus completing the rope winding operation of the bend 33. Remove the bend 33 from the drive mounting plate 7.
[0033] Since the bent tube 33 is a metal product, directly applying glue to its surface and wrapping the rope around it will result in insufficient adhesion. First, glue and wrap a layer of bottom cloth strips on the surface of the bent tube 33, and then glue and wrap the rope around the bottom strip on the surface of the bent tube 33 to enhance the adhesion.
[0034] When the outer diameter of the arc-shaped pressure plate 18 does not match that of the bend 33 to be wound, unscrew the pressure plate stud 15, remove the two tension springs 14, and the arc-shaped pressure plate 18 can be separated from the pressure plate column 13. Replace with a suitable arc-shaped pressure plate 18, and reinstall the tension springs 14 and pressure plate stud 15.
[0035] When changing to a rope of different thickness, loosen the two adjusting nuts 31, rotate the screw 30, adjust the up and down position of the rope pressing head 17, and after adjustment, tighten the two adjusting nuts 31.
[0036] The rope pressing frame 24 of this utility model can adjust the gap between the rope pressing shaft and the inclined plate 22 after loosening the bolts. After adjusting the gap, tighten the bolts.
[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
