Description

Technical Field

[0001] This utility model belongs to the field of hose manufacturing technology, specifically relating to a variable diameter structure for a coiling machine. Background Technology

[0002] Rubber hoses are tubular rubber products used to transport gases, liquids, slurries, or granular materials. During the production of rubber hoses, workers use hose coiling machines to wind up the produced hoses. Patent application number "CN202420426416.9" discloses a wire and cable winding device, including: a winding mechanism with a threading hole fixedly mounted on an arc-shaped plate; a rotating plate fixedly mounted on the inner side of the arc-shaped plate; movable rods on both sides of the lower end of the rotating plate; the rotating plate being slidably connected to a variable-diameter gear and a variable-diameter disc via the movable rods; the rotating plate having a limiting groove slidably connected to a limiting block fixedly mounted on the rotating rod; the rotating rod being fixedly mounted on one side of the rotating disc; the variable-diameter disc being slidably connected to the rotating rod; a circular pin slidably mounted on the rotating disc; the variable-diameter gear and the variable-diameter disc having the same inner diameter and both having multiple variable-diameter grooves; and a manual crank mounted on the variable-diameter gear. The present invention provides a wire and cable winding device that uses a variable radius winding mechanism to achieve better winding effect on wires and cables of different thicknesses, thereby avoiding damage to the cable surface.

[0003] The aforementioned patent uses a variable radius winding mechanism to adjust the inner diameter of the hose wound on the coiling machine. However, when removing the wound hose, the operator needs to adjust the winding mechanism to shrink it. The shrunken winding mechanism makes it easier for the operator to remove the hose. However, after adjustment, the operator needs to precisely move the support plate back to its original position to ensure the device's coiling effect on the hose. This results in the user spending a lot of time adjusting the size of the winding mechanism, which affects the device's working efficiency. Utility Model Content

[0004] This invention provides a variable diameter structure for a coiling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable diameter structure for a coiling machine, comprising a main body, a drive mechanism, a support plate, and a baffle plate. The drive mechanism is mounted on an electric rotating shaft of the main body. Several support plates are mounted on the drive mechanism. A movable plate is slidably mounted on the support plate. A jacking rod is provided on the inner wall of the movable plate. An electric rotating block is mounted on the support plate. A jacking groove is provided on the electric rotating block. The jacking rod passes through the jacking groove. The baffle plate is hinged to the side wall of the end face groove of the support plate. A connecting rod is hinged to the baffle plate. A telescopic cylinder is installed inside the end face groove of the support plate. A movable frame is mounted on the telescopic cylinder. The connecting rod is slidably mounted on the movable frame.

[0006] Preferably, the side wall of the actuating rod has a protrusion on the portion inside the actuating groove, the side wall of the actuating groove has a groove that mates with the protrusion on the side wall of the actuating rod, and several ball bearings are rotatably mounted on the protrusion on the side wall of the actuating rod.

[0007] Preferably, an electric rotating plate is installed on the bottom protruding side wall of the movable plate, and the length of the electric rotating plate is the same as the distance between the two ends of the top moving groove on the horizontal plane.

[0008] Preferably, the support plate is provided with a groove that engages with the bottom protrusion of the movable plate.

[0009] Preferably, the top sidewall of the groove in which the connecting rod is mounted on the support plate has a support protrusion at one end near the barrier plate.

[0010] Preferably, several ball bearings are rotatably mounted on the side wall of the groove where the connecting rod is mounted on the movable frame.

[0011] Preferably, the bottom surface of the barrier plate is sloping.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a support plate, a movable plate, an electric rotating block, a jacking rod, and a jacking groove. When the electric rotating block rotates, the electric rotating plate adjusts the position of the movable plate. When the movable plate moves into the groove on the support plate, its support for the hose is released, allowing the user to easily remove the hose. Controlling the electric rotating block to rotate in the opposite direction enables the movable plate to quickly reset, eliminating the need for fine-tuning the plate's position and improving the efficiency of removing the wound hose. This ensures the device's overall efficiency. The electric rotating plate ensures the stability of the movable plate during use. The support protrusion limits the position of the barrier plate when adjusted by the operator, preventing excessive rotation angle from affecting the telescopic cylinder's adjustment of the barrier plate.

[0021] Please see Figure 1-6The present invention provides the following technical solution: a variable diameter structure for a coiling machine, comprising a main body 1, a drive mechanism 2, a support plate 3, and a baffle plate 4. The drive mechanism 2 is provided on the electric rotating shaft of the main body 1. Several support plates 3 are installed on the drive mechanism 2. A movable plate 31 is slidably installed on the support plate 3. A top-moving rod 33 is provided on the inner wall of the movable plate 31. An electric rotating block 32 is installed on the support plate 3. A top-moving groove 34 is provided on the electric rotating block 32. The top-moving rod 33 passes through the top-moving groove 34. A baffle plate 4 is hinged to the side wall of the end face groove of the support plate 3. A connecting rod 41 is hinged to the baffle plate 4. A telescopic cylinder is installed inside the end face groove of the support plate 3. A movable frame 42 is installed on the telescopic cylinder. The connecting rod 41 is slidably installed on the movable frame 42.

[0022] The drive mechanism 2 is mounted on an electric rotating shaft on the main body 1. The electric rotating shaft provides power for the device to wind the hose. The drive mechanism 2 is used to adjust the position of the support plate 3, thereby adjusting the inner diameter of the hose wound on the support plate 3. This prevents the hose located on the inner side from being damaged due to stress, extending the service life of the hose. The main body 1 and the drive mechanism 2 are common and mature structures, and do not need to be described in detail in the instruction manual. The moving plate 31 is slidably mounted on the support plate 3. The actuating rod 33 on the moving plate 31 is slidably mounted on the actuating groove 34 on the electric rotating block 32. When the electric rotating block 32 rotates, the actuating groove 34 will be rotated by the electric rotating block 32. As the device rotates, the electric rotating block 32 is pushed by the side wall of the pushing groove 34. The pushed electric rotating block 32 moves the moving plate 31, thus adjusting the position of the moving plate 31. When the device is in use, the electric rotating block 32 is started. The electric rotating block 32 adjusts the position of the moving plate 31 through the cooperation of the pushing rod 33 and the pushing groove 34. After the moving plate 31 is moved, the thickness of the support plate 3 and the moving plate 31 installed together is increased. After the hose is wound up, the electric rotating block 32 is controlled to rotate in the opposite direction. The moving plate 31 is moved back to its original position by the electric rotating block 32 with the cooperation of the pushing rod 33 and the pushing groove 34. The thickness of the support plate 3 and the moving plate 31 installed together is reduced. At this time, the moving plate 31 has a greater impact on the adhesive. With the support of the tube released, the user can quickly remove the tangled hose from the support plate 3. This reduces the efficiency of removing the tangled hose. The adjustment method of the moving plate 31 allows the user to quickly adjust its position. When the user adjusts the position of the moving plate 31, the position of the support plate 3 does not change, eliminating the need for the user to adjust the position of the support plate 3 and improving the efficiency of removing the tangled hose. The blocking plate 4 is used to limit the hose tangled on the support plate 3, preventing the hose from detaching from the support plate 3 during the winding process. A connecting rod 41 is hinged to the blocking plate 4, and the blocking plate 4 is connected to the telescopic cylinder through the cooperation of the connecting rod 41 and the moving frame 42. The position of the moving frame 42 can be adjusted by the telescopic cylinder. When the moving frame 42 moves, it will move the connecting rod 41. The moving connecting rod 41 pulls the barrier plate 4. The pulled barrier plate 4 rotates around the hinge axis of the barrier plate 4, thereby realizing the adjustment of the position of the barrier plate 4 and ensuring that the user will not be obstructed when removing the hose. The connecting rod 41 is slidably installed on the moving frame 42. When the barrier plate 4 is rotated by the connecting rod 41, the position of the hinge axis of the barrier plate 4 and the connecting rod 41 changes in the horizontal direction. At this time, the connecting rod 41 moves along the groove of the moving frame 42, ensuring that the pulled connecting rod 41 can smoothly rotate the barrier plate 4.

[0023] Specifically, the side wall of the actuating rod 33 has a protrusion on the part inside the actuating groove 34, and the side wall of the actuating groove 34 has a groove that matches the protrusion on the side wall of the actuating rod 33. Several balls are rotatably mounted on the protrusion on the side wall of the actuating rod 33.

[0024] The cooperation between the side wall protrusion of the jacking rod 33 and the side wall groove of the jacking groove 34 plays a limiting role, ensuring the stability of the cooperation between the jacking rod 33 and the jacking groove 34 during the use of the device. During the process of the jacking rod 33 being pushed by the side wall of the jacking groove 34, the rotating ball bearings mounted on the jacking rod 33 begin to rotate. The rotating ball bearings reduce the wear on the jacking rod 33 and the jacking groove 34 during the movement, thus extending the service life of the jacking rod 33.

[0025] Specifically, an electric rotating plate 5 is installed on the raised side wall at the bottom of the movable plate 31. The length of the electric rotating plate 5 is the same as the distance between the two ends of the top moving groove 34 on the horizontal plane.

[0026] When the support plate 3 and the movable plate 31 are separated, the electric rotating plate 5 is controlled to rotate. The rotating electric rotating plate 5 contacts the support plate 3, and the electric rotating plate 5 in contact with the support plate 3 plays the role of supporting the movable plate 31, ensuring the stability of the movable plate 31 during the use of the device. The length of the electric rotating plate 5 is guaranteed. When the top rod 33 moves to the limit position of the top groove 34, the electric rotating plate 5 can fix the movable plate 31, which is convenient for the user to fix the movable plate 31 after it has moved to the limit position. This avoids the user having to make fine adjustments to the position of the movable plate 31 and improves the efficiency of the user in adjusting the position of the movable plate 31.

[0027] Specifically, the support plate 3 is provided with a groove that matches the bottom protrusion of the movable plate 31.

[0028] The shape of the bottom protrusion of the movable plate 31 ensures that, during the process of the movable plate 31 being pushed, the bottom protrusion of the movable plate 31 is always located inside the groove that mates with the bottom protrusion of the supporting plate 3. The mating of the bottom protrusion of the movable plate 31 and the mating groove ensures that the space between the supporting plate 3 and the movable plate 31 is not exposed to the external environment, preventing external debris from entering the space between the supporting plate 3 and the movable plate 31, and ensuring that the movement of the movable plate 31 is not obstructed. The mating of the bottom protrusion of the movable plate 31 and the mating groove also serves as a limit, ensuring the stability of the movable plate 31 during the movement process.

[0029] Specifically, a support protrusion 43 is provided on the top side wall of the groove for mounting the connecting rod 41 on the support plate 3 near the end of the barrier plate 4.

[0030] The support protrusion 43 serves to support the connecting rod 41. The shape of the support protrusion 43 ensures that when the connecting rod 41 moves to its limit position under the drive of the moving frame 42, the barrier plate 4 tilts to one side of the moving frame 42. The tilted barrier plate 4 ensures that the moving frame 42 can smoothly rotate with the barrier plate 4 through the connecting rod 41, thus ensuring the adjustment effect of the connecting rod 41 on the position of the barrier plate 4.

[0031] Specifically, several ball bearings are rotatably mounted on the side wall of the groove for mounting the connecting rod 41 in the movable frame 42.

[0032] Several ball bearings are provided on the side wall of the groove for mounting the connecting rod 41 in the movable frame 42. During the movement of the connecting rod 41, the ball bearings will be rotated by the connecting rod 41. The rotating ball bearings reduce the friction force on the connecting rod 41 during the movement and reduce the obstruction encountered by the connecting rod 41 during the sliding process on the movable frame 42. This makes it easier for the user to adjust the position of the connecting rod 41. The ball bearings are located on the two side walls of the groove for mounting the connecting rod 41 in the movable frame 42, which ensures the working effect of the ball bearings.

[0033] Specifically, the bottom surface of the barrier plate 4 is sloping.

[0034] The bottom shape of the barrier plate 4 ensures that the barrier plate 4 can be completely screwed into the groove of the mounting frame 42 during rotation. The shape of the barrier plate 4 ensures that when the barrier plate 4 is in the state of blocking the rubber tube wrapped on the support plate 3, the barrier plate 4 will seal the groove of the mounting frame 42 to prevent external debris from entering the groove of the mounting frame 42.

[0035] The working principle and usage process of this utility model are as follows: The support plate 3 is adjusted to a suitable position by the drive mechanism 2, and the rubber tube is wound around the support plate 3. After the rubber tube wound around the support plate 3 is fixed, the electric rotating plate 5 is controlled to rotate, and the support of the electric rotating plate 5 on the moving plate 31 is released. The electric rotating block 32 is started. As the electric rotating block 32 rotates, the side wall of the top moving groove 34 pushes the top moving rod 33. The moving plate 31 begins to move under the cooperation of the top moving rod 33 and the top moving groove 34. The support plate 3 and the moving plate 3 are installed together. As the thickness of the movable plate 31 decreases, the support of the movable plate 31 on the hose is released, the telescopic cylinder is controlled to retract, and the telescopic cylinder moves the movable frame 42 and the connecting rod 41. As the movable frame 42 moves, the connecting rod 41 pulls the barrier plate 4 to rotate. As the barrier plate 4 rotates, the connecting rod 41 moves on the movable frame 42. When the connecting rod 41 contacts the support protrusion 43, the barrier plate 4 releases its obstruction of the hose, and the hose is removed from the support plate 3. The electric rotating block 32, the electric rotating plate 5, and the telescopic cylinder are controlled to move back to their original positions.
