Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1: Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a multi-station automatic polishing device for wooden clothes hangers, including a workbench 1, a support 2 fixed on the top of the workbench 1, and four sets of movable frames 3 with a left-right symmetrical design slidingly connected to the inner wall of the workbench 1. Each of the four sets of movable frames 3 is provided with a clamping component 4 on its top.

[0025] The workbench 1 serves as the basic support structure for the entire device, providing an installation platform for other components, bearing the weight of the entire device, and ensuring the relative stability of each component during operation. The bracket 2 is used to support components such as the first cylinder 5, and also provides guidance and support for the up-and-down movement of the push plate 6, enabling the push plate 6 to move stably vertically under the drive of the first cylinder 5. The movable frame 3 can slide on the inner wall of the workbench 1 to support the clamping component 4. By moving on the workbench 1, the position of the clamping component 4 can be adjusted to adapt to the clamping requirements of wooden hangers of different sizes, realizing multi-station operation. The clamping component 4 can fix the wooden hanger to be polished through its internal structure.

[0026] The top of the bracket 2 is equipped with a vertically arranged first cylinder 5. The inner wall of the bracket 2 is slidably connected to a push plate 6, and the top of the push plate 6 is fixedly connected to the piston rod of the first cylinder 5 through a flange. The bottom of the push plate 6 is fixed with a limit frame 7. The outer side of the limit frame 7 is slidably connected to a movable frame 8 with a left-right symmetrical design. A polishing machine 9 is installed on one side of the movable frame 8.

[0027] The first cylinder 5, through the extension and retraction of the piston rod, drives the push plate 6 to move vertically up and down on the inner wall of the bracket 2. Driven by the first cylinder 5, the push plate 6 transmits the linear motion of the first cylinder 5 to the limiting frame 7. The limiting frame 7 provides a sliding connection structure for the movable frame 8, allowing it to slide left and right on its outer side. Simultaneously, the limiting frame 7 also serves as the mounting base for the toothed plate 22, providing a power transmission structure for the left and right movement of the movable frame 8. By sliding left and right on the limiting frame 7, the movable frame 8 can drive the polishing machine 9 to move left and right, enabling polishing operations on different positions of the wooden hanger. The polishing machine 9 consists of a protective shell, a motor, and a polishing disc. The protective shell protects the motor, which drives the polishing disc to rotate. The polishing disc, through its own rotational movement... The surface of the wooden hanger clamped on the clamping assembly 4 can be polished to remove burrs, defects and other imperfections, thus improving the surface quality of the wooden hanger. It should be noted that the first cylinder 5 is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve and a flow control valve. During use, the air compressor compresses the ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, and delivers it to the control valve through an air pipe. The directional control valve switches the airflow channel according to the electrical signal to determine the extension and retraction direction of the first cylinder 5. The flow control valve adjusts the airflow speed and controls the movement speed of the first cylinder 5. Compressed air enters the rod chamber or rodless chamber of the first cylinder 5, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0028] The clamping assembly 4 includes a mounting plate 41 fixed to one side of the movable frame 3. Two sets of push blocks 42 are provided on one side of the mounting plate 41. Two sets of top rods 43 are rotatably connected to the inner wall of the push blocks 42. Four sets of clamping arms 44 with symmetrical upper and lower design are rotatably connected to one side of the mounting plate 41. The outer side of the clamping arm 44 is rotatably connected to one end of the top rod 43. A clamping block 45 is installed on one side of the clamping arm 44.

[0029] Mounting plate 41 serves as the base component of clamping assembly 4, providing mounting positions for other clamping-related components. It is also connected to movable frame 3, allowing the entire clamping assembly 4 to move with it. Two sets of push blocks 42, driven by the second cylinder 18, move laterally via connecting rod 19, providing a pushing force to the top rod 43. The two sets of top rods 43 transmit the pushing force of the push blocks 42, converting the lateral movement of the push blocks 42 into the swinging motion of the clamping arms 44. The four sets of clamping arms 44 swing under the action of the top rods 43, causing the clamping blocks 45 to move closer to or away from the wooden hanger, thus clamping or releasing the wooden hanger. 5. Direct contact with the wooden hanger increases the contact area and provides a stable clamping force, ensuring that the wooden hanger will not loosen or shift during polishing. When in use, the second cylinder 18 on the mounting plate 41 is activated. The cylinder 18 drives the connecting rod 19 to move laterally through the piston rod. The connecting rod 19 pushes the two sets of push blocks 42 to move synchronously. The push blocks 42 push the top rod 43 to move. Since the other end of the top rod 43 pushes the clamping arm 44 rotatably connected to the mounting plate 41, the four sets of clamping arms 44 symmetrically positioned above and below can swing along the mounting plate 41. The clamping block 45 on one side of the clamping arm 44 can firmly clamp the wooden hanger.

[0030] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, slide rails 10 are fixed on both sides of the workbench 1, and a slider 11 is fixed on one side of the movable frame 3, with one side of the slider 11 slidably connected to the inner wall of the slide rail 10.

[0032] The slide rail 10 is provided to provide a sliding track for the slider 11, ensuring the linearity and stability of the movable frame 3 in the horizontal direction. The slider 11 is slidably connected to the inner wall of the slide rail 10, so that the movable frame 3 can slide smoothly under the guidance of the slide rail 10, reducing friction and shaking during the movement of the movable frame 3.

[0033] Specifically, the workbench 1 is equipped with two sets of first motors 12 with a symmetrical design. The output end of the first motor 12 is fixed with a worm gear 13. The outer side of the worm gear 13 is meshed with a worm wheel 14. The axis of the worm wheel 14 is fixed with a horizontally arranged positive and negative threaded rod 15. The outer side of the positive and negative threaded rod 15 is threadedly connected to the inner wall of the movable frame 3, and both ends of the positive and negative threaded rod 15 are rotatably connected to the inner wall of the workbench 1.

[0034] Two sets of first motors 12 serve as the power source for driving the movable frame 3 to move. The worm gear 13 can rotate under the drive of the first motor 12. Through meshing with the worm wheel 14, the rotational motion is transmitted to the worm wheel 14, realizing the transmission and steering of power. The worm wheel 14 can rotate under the drive of the worm gear 13, driving the positive and negative threaded rods 15 to rotate. At the same time, the worm wheel 14 and worm gear 13 transmission has self-locking properties, which can ensure that the movable frame 3 can maintain a stable position after it stops moving. The positive and negative threaded rods 15 can rotate under the drive of the worm wheel 14. Due to its positive and negative thread design, the movable frames 3 on the left and right sides can move in opposite directions at the same time, realizing the synchronous adjustment of the movable frame 3.

[0035] Specifically, the inner wall of the workbench 1 is fixed with two sets of baffles 16, and a limit rod 17 is fixed on one side of the baffle 16, and the outer side of the limit rod 17 is slidably connected to the inner wall of the movable frame 3.

[0036] The baffle 16 provides an installation position for the limit rod 17, and also plays a certain role in isolation and protection, preventing the movable frame 3 from interfering with other internal components during movement. The limit rod 17 is set to provide additional guidance and support for the movement of the movable frame 3, further ensuring the straightness and stability of the movement of the movable frame 3, and preventing the movable frame 3 from deviating or tilting during movement.

[0037] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0038] Specifically, a second cylinder 18 is installed on one side of the mounting plate 41, and the outer side of the second cylinder 18 is fixedly connected to the inner wall of the movable frame 3 by screws. The piston rod of the second cylinder 18 is fixed with a horizontally arranged connecting rod 19, and the two ends of the connecting rod 19 are respectively fixedly connected to one side of the two sets of push blocks 42.

[0039] The second cylinder 18, through the extension and retraction of the piston rod, can drive the connecting rod 19 and the push block 42 to move laterally. Under the drive of the second cylinder 18, the connecting rod 19 can evenly transmit the linear motion of the second cylinder 18 to the two sets of push blocks 42, so that the two sets of push blocks 42 move synchronously, ensuring that the opening and closing actions of the clamping arm 44 are coordinated and consistent. It should be noted that the working principle of the second cylinder 18 is the same as that of the first cylinder 5 mentioned above, and both are existing technologies, so they will not be elaborated on here.

[0040] Specifically, the inner wall of the limiting frame 7 is fixed with two sets of sliding rods 20, the outer side of the sliding rods 20 is slidably connected to the limiting plate 21, and the outer side of the limiting plate 21 is fixedly connected to the outer side of the movable frame 8.

[0041] The slide bar 20 is provided to provide a sliding track for the limiting plate 21, ensuring the linearity and stability of the limiting plate 21 in the horizontal direction. The limiting plate 21 is used to connect the movable frame 8 to the slide bar 20, so that the movable frame 8 can slide smoothly left and right under the guidance of the slide bar 20, while limiting the range of movement of the movable frame 8 to a certain extent.

[0042] Specifically, the top of the limiting frame 7 is equipped with a toothed plate 22 with a symmetrical design, the top of the movable frame 8 is equipped with a second motor 23, the output end of the second motor 23 is fixed with a gear 24, and the outer side of the gear 24 is meshed with one side of the toothed plate 22.

[0043] The toothed plate 22 is connected to the gear 24 at the output end of the second motor 23, which provides a power transmission path for the left and right movement of the movable frame 8. It converts the rotational motion of the second motor 23 into the linear motion of the movable frame 8. The second motor 23 serves as the power source for driving the left and right movement of the movable frame 8. The gear 24 is connected to one side of the toothed plate 22 and can rotate under the drive of the second motor 23. Through meshing with the toothed plate 22, it transmits the rotational motion of the second motor 23 to the toothed plate 22, thereby driving the movable frame 8 to move left and right.

[0044] Working principle: When this multi-station automatic polishing device for wooden hangers is working, the wooden hanger to be polished is first placed at the clamping assembly 4. The second cylinder 18 on the mounting plate 41 is started, and its piston rod drives the connecting rod 19 to move laterally. The connecting rod 19 causes the two sets of push blocks 42 to move synchronously. The push blocks 42 push the top rod 43, and the other end of the top rod 43 pushes the clamping arm 44 rotatably connected to the mounting plate 41, causing the four sets of clamping arms 44 to swing symmetrically. The clamping block 45 on one side of the clamping arm 44 firmly clamps the wooden hanger. Then, the first motor 12 is started, and the first motor 12 drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 14 that meshes with it to rotate. The worm wheel 14 drives the positive and negative threaded rods 15 to rotate. Since the positive and negative threaded rods 15 are threadedly connected to the inner wall of the movable frame 3, and the movable frame 3 is in operation, the worm gear 12 is used to polish the wooden hanger. The first motor 12 drives the worm gear 13 to rotate, and the worm wheel 14 drives the positive and negative threaded rods 15 to rotate. Since the positive and negative threaded rods 15 are threadedly connected to the inner wall of the movable frame 3, and the movable frame 3 is used to polish the wooden hanger, the first motor 12 drives the worm gear 13 to rotate, and the worm wheel 13 drives the worm wheel 14 to rotate, and the worm wheel 14 drives the worm wheel 14 to rotate. The positive and negative threaded rods 15 are threadedly connected to the inner wall of the movable frame 3, and the movable frame 3 is used to polish the wooden hanger. The first motor 12 drives the worm gear 13 to rotate, and the worm wheel The frame 3 slides on the slide rail 10 via the slider 11 and is further guided by the limit rod 17, so that the four sets of movable frames 3, which are symmetrical on the left and right, move synchronously to the appropriate position to adjust the polishing position of the wooden clothes hanger. Then, the first cylinder 5 is started, and its piston rod drives the push plate 6 to slide down the inner wall of the bracket 2 through the flange. The push plate 6 drives the limit frame 7, the movable frame 8 and the polishing machine 9 to move down as a whole, so that the polishing machine 9 is close to the wooden clothes hanger. Finally, the second motor 23 is started, and the gear 24 at its output end meshes with the toothed plate 22 at the top of the limit frame 7 to drive the movable frame 8 to slide left and right on the slide rod 20 on the outside of the limit frame 7. The polishing machine 9 on one side of the movable frame 8 moves left and right accordingly to perform full automatic polishing on the surface of the wooden clothes hanger. After polishing is completed, the components are reset in reverse order, and the polished wooden clothes hanger can be taken out.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
