Description

Technical Field

[0001] This invention relates to the field of garment production line technology, specifically to a garment segmented hanging transport device. Background Technology

[0002] With the rapid development of the apparel and home textile industries, assembly line production has been widely adopted by many enterprises. Garment hanging conveyor systems, as core equipment that significantly improves the efficiency of finished garment transportation and circulation, are increasingly being used. This system typically includes a circular main rail with several workstations spaced along its length. Each workstation has a corresponding processing station below it. Garment hangers, with pieces of clothing suspended on them, are conveyed along the main rail to the designated workstation for processing under system control. After processing, they re-enter the main rail via the exit swing head at that workstation and are then conveyed to the next workstation for further processing. In actual operation, the hanger wheels roll on the exit assembly. Intermittent stopping and releasing are achieved through a stop mechanism on the exit assembly, causing the hanger wheels to fall sequentially onto the main rail. Then, pushers evenly spaced on the main rail push the hangers forward one by one, completing the entire conveying process.

[0003] To facilitate the installation, maintenance, and quick replacement of faulty sections, existing garment hanging conveyor systems mostly adopt a segmented connecting rod structure above the main rail and below the transmission chain. The connecting rods are fastened together by bolts, and the push rod is fixed to the pre-set screw hole position on the connecting rod by bolts or rivets. However, the bolt connection method of the segmented connecting rod and the bolt and rivet fixing method of the push rod make the installation and disassembly process cumbersome, requiring special tools and resulting in low maintenance efficiency. Furthermore, the push rod can only be fixed to a limited number of pre-set screw hole positions on the connecting rod, and the installation position cannot be flexibly adjusted according to production needs. The push rod spacing is a fixed value, which can only adapt to a specific range of garment sizes. When producing different types and sizes of garments, it is necessary to disassemble and reinstall the push rod or even replace the entire connecting rod, which is difficult to meet the current production needs of the garment industry for small batches and multiple varieties. At the same time, a large number of bolt connections will loosen after long-term use, requiring frequent inspection and tightening. Otherwise, it will not only affect the operation of the push rod but also create safety hazards. Moreover, when the connecting rod is damaged and needs to be replaced, it is necessary not only to remove the connecting rod from the track but also to reinstall the push rod connected to the connecting rod on the new connecting rod, further reducing the efficiency of disassembly and maintenance. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, the present invention provides a segmented hanging transportation device for clothing, which has the advantages of quick disassembly and assembly, flexible and adjustable push rod installation spacing and stable structure. It solves the problems of cumbersome disassembly and maintenance of segmented connecting rod structure, limited installation push rod spacing and easy vibration of existing clothing hanging systems.

[0005] (II) Technical Solution: To achieve the goals of rapid assembly and disassembly of the above-mentioned structure, flexible adjustment of the push rod installation spacing, and structural stability, the present invention provides the following technical solution: A segmented hanging transport device for clothing, comprising a support frame and a track fixedly installed below the support frame. Two or more sets of end-to-end transmission racks are slidably installed below the support frame. Each transmission rack has a groove and a buckle processed at both ends. Adjacent transmission racks are connected to form a chain through the grooves and buckles. The transmission rack includes two sets of... The rack assembly consists of interlocking rack units. Each rack unit has an integrally machined support plate at both the top and bottom of its teeth. The support plate at the lower end of the rack unit is equipped with a mounting base with a push rod. Quick-release plates are mounted on both sides of the mounting base. The inner side of the quick-release plate has a mounting bracket that overlaps with the lower support plate. The quick-release plate is also movably mounted with a snap-fit ​​tooth that connects to the rack unit. After the mounting bracket overlaps with the support plate, the snap-fit ​​tooth is inserted along the tooth groove of the rack unit to limit the quick-release plate along the length direction of the rack unit.

[0006] Preferably, a connecting plate is integrally formed at the mating surface of the two sets of rack units of each transmission rack. The thickness of the connecting plate is less than the thickness of the rack unit. The upper and lower end faces of the connecting plate form two sets of toothed grooves extending along the length direction of the transmission rack between the rack units on both sides.

[0007] Preferably, the two rack units of each set of transmission racks are fixedly connected, and the slot and the buckle are respectively machined at both ends of the rack unit.

[0008] Preferably, the quick-release plate is machined with fixing holes, and the side of the quick-release plate is also machined with quick-release holes for fixing it to the mounting base, and bolts for fixing and connecting to the mounting base are installed in the quick-release holes.

[0009] Preferably, the fixing hole is machined on the side of the quick-release plate, and a wedge-shaped slider with an inclined surface is slidably mounted coaxially on the snap-fit ​​tooth. The wedge-shaped slider is inserted into the fixing hole, and the inclined surface is provided on the lower end face of the wedge-shaped slider. A spring is connected between the wedge-shaped slider and the snap-fit ​​tooth. One end of the spring is fixedly connected to the snap-fit ​​tooth, and the other end of the spring is fixedly connected to the wedge-shaped slider. When the snap-fit ​​tooth is inserted vertically downward into the tooth groove of the rack unit, the upper surface of the quick-release plate presses the wedge-shaped slider to slide towards the snap-fit ​​tooth and compresses the spring. When the wedge-shaped slider moves vertically downward to the fixing hole position, the spring resets and pushes the wedge-shaped slider to insert into the fixing hole.

[0010] Preferably, the fixing hole is machined on the upper surface of the quick-release plate, and a fixing shaft is coaxially fixed in the fixing hole. An annular limiting platform with a notch is coaxially sleeved on the fixing shaft. A cam is eccentrically and rotatably sleeved on the outer periphery of the fixing shaft. Stepped blocks with a size corresponding to the notch are protruding on the inner wall of the shaft hole of the cam in a spiral stepped array distributed along the axial direction. The outer peripheral surface of the cam abuts against the tooth surface of the transmission rack and forms a friction transmission engagement. During the movement of the quick-release plate along the transmission rack with the mounting seat, the transmission rack drives the cam to rotate. Whenever the stepped block that is engaged with the limiting platform rotates to the notch position, the stepped block passes through the notch along the axial direction and causes the cam to descend axially. When the topmost stepped block falls and gets stuck in the notch, the cam is circumferentially limited and stops rotating. At this time, the convex end of the cam is wedged with the transmission rack to restrict the quick-release plate from continuing to move.

[0011] Preferably, during installation, the step block at the lowest end of the cam is installed along the direction of the notch, and when the topmost step block falls and gets into the notch, the number of teeth the cam moves on the transmission rack is equal to the number of teeth between the two sets of mounting seats on the transmission rack.

[0012] Preferably, the diameter of the limiting platform is larger than the inner diameter of the step block, and the limiting platform is detachably connected to the fixed shaft.

[0013] Preferably, when the last set of stepped blocks falls into the notch, the bottom surface of the stepped block abuts against the bottom surface of the notch and its top surface is coplanar with the top surface of the limiting platform, thereby completely limiting the cam in the axial and circumferential directions; the lowest stepped block is positioned higher than the bottom surface of the cam.

[0014] Preferably, the surface of the cam is provided with an anti-slip texture layer, and when the cam's convex end is wedged tightly with the transmission rack, the tooth surfaces of the cam and the transmission rack are in an interference fit; the bottom end face of the fixing hole is lower than the top end face of the platform and higher than its bottom end face.

[0015] Preferably, the stepped blocks are made of flexible material.

[0016] Preferably, a sliding groove is machined below the support frame, and the support plate at the upper end of the rack unit is slidably connected to the sliding groove. Two or more sets of drive gears that mesh with one side of the rack unit of the transmission rack are also fixedly installed on the support frame. A drive motor is connected above the drive gears, and the drive motor is fixedly installed on the support frame.

[0017] Preferably, two or more sets of pulleys are equidistantly connected in the sliding groove along the length of the support frame, and the support plate is slidably connected to the pulleys.

[0018] Preferably, a hanger wheel is slidably mounted on the track, and a hanger is rotatably mounted below the hanger wheel. When the mounting base moves with the transmission rack, the push rod pushes the hanger wheel to slide along the track.

[0019] Preferably, one side of the locking teeth on both sides of the mounting base has a double-tooth structure, and the other side has a single-tooth structure.

[0020] Preferably, quick-release plates are respectively mounted on both sides of the mounting base, wherein a single fixed shaft is provided on the quick-release plate located on one side of the mounting base, and two fixed shafts are provided at intervals along the length direction of the transmission rack on the quick-release plate located on the other side of the mounting base.

[0021] (III) Beneficial Effects: Compared with the prior art, the present invention provides a segmented hanging transportation device for clothing, which has the following beneficial effects: 1. This segmented hanging transport device for clothing connects the hanging platform on the inner side of the quick-release plate with the support plate at the lower end of the rack unit. The locking teeth are inserted into the tooth groove of the rack unit for limiting the position. The wedge-shaped slider driven by the spring automatically springs into the fixing hole on the side of the quick-release plate to complete the anti-detachment locking structure. Compared with the traditional technology of fastening with bolts or rivets, this device achieves a stable connection between the mounting base and the transmission rack and quick tool-free disassembly. It completely eliminates the need for cumbersome fastening steps using special tools, thereby greatly improving installation efficiency and facilitating flexible adjustment of the position according to production needs.

[0022] 2. This segmented hanging transport device for clothing uses a splicing structure in which adjacent transmission racks are connected to each other by slots and buckles to form a chain. Compared with the traditional integral structure or the technical structure of bolted splicing connecting rods, it realizes the independent extraction and offline replacement of a single faulty transmission rack and its corresponding mounting seat. During maintenance, there is no need to disassemble the entire production line conveyor belt, which greatly improves the efficiency of faulty section maintenance and replacement and effectively reduces equipment downtime maintenance costs.

[0023] 3. This segmented hanging transport device for clothing utilizes a frictional transmission mechanism between a cam and a transmission rack. It also employs a step-by-step descent and mechanical limiting linkage mechanism formed by a spirally arranged array of stepped blocks on the inner wall of the cam and a notched limiting platform. Compared to traditional installation methods that rely entirely on manual measurement or visual comparison of tooth spacing, this application eliminates the need for manual tooth counting during the installation process. Furthermore, the detachable connection of the limiting platform allows for rapid axial disassembly of the cam, significantly simplifying the replacement, maintenance, and repositioning of the mounting base.

[0024] 4. This segmented hanging transport device for clothing uses a flexible stepped block spirally distributed on the inner wall of the camshaft hole to form a multi-point contact structure with the outer circumference of the fixed shaft. This structure can evenly distribute the mechanical vibration stress generated during transmission to each contact point. The elastic deformation of the flexible stepped block absorbs and dissipates the rigid impact kinetic energy during transmission, forming a flexible shock absorption and damping structure between the fixed shaft and the cam. This effectively reduces the mechanical vibration during the operation of the mounting base, avoids loosening of connections and structural metal fatigue caused by long-term high-frequency vibration, and greatly improves the stability of the device operation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 Please see Figures 1-8A segmented hanging transport device for clothing includes a support frame 1 and a track 2 fixedly installed below the support frame 1. Two or more sets of end-to-end transmission racks 3 are slidably installed below the support frame 1. Each end of the transmission rack 3 has a groove 31 and a buckle 32 machined at its two ends. Adjacent transmission racks 3 are connected to form a chain by engaging the grooves 31 and buckles 32. Each transmission rack 3 consists of two sets of mutually fixed and embedded rack units 33. The track 2 has an I-shaped or inverted T-shaped cross-section to facilitate smooth sliding of subsequent related components on the track 2 and provide reliable guiding support. The two sets of rack units 33 are mutually abutting. The inner surface of the rack is machined with matching longitudinal positioning protrusions and positioning grooves. Through tight fitting, the two sets of rack units 33 are firmly spliced ​​into a whole. This interlocking combination structure can not only greatly improve the bending section modulus and rigidity of the transmission rack 3, preventing the transmission rack 3 from bending deformation or lateral misalignment during long-term force transmission and heavy load bearing, but also can extremely effectively improve the alignment accuracy between adjacent transmission racks 3, ensuring the continuity and stability of the transmission rack 3 when sliding under the support frame 1, and avoiding the occurrence of mechanical operation jamming from the structural source. The rack unit 33 has integrated support plates 34 at both the top and bottom of the tooth tip. The support plates 34 are arranged in an equidistant array on the tooth tip along the length of the rack unit 33. The floating end edge of the support plate 34 is chamfered and ground to present a smooth transition and anti-cutting protective surface. The support plates 34 and the main body of the rack unit 33 are made of the same metal or engineering plastic to ensure the continuity and uniformity of the overall force transmission of the rack unit 33 structure. The support plates 34 are directly integrated on the top and bottom of the tooth tip of the rack unit 33. On the one hand, it provides an extremely flat and sufficiently wide planar overlap and load-bearing platform for subsequent external installation components, which greatly disperses the local vertical pressure generated by bearing heavy objects. On the other hand, it plays a shield-like limiting and shielding protection role for the core tooth structure of the rack unit 33 in the vertical space direction, preventing the rack unit 33 from being hit or rubbed by foreign objects from the vertical direction in the complex assembly line operation environment.A mounting base 4 with a push rod 41 is mounted on the support plate 34 at the lower end of the rack unit 33. Quick-release plates 5 are mounted on both sides of the mounting base 4. Hanging platforms 51, overlapping the lower support plate 34, are machined on the inner side of the quick-release plates 5. The main structure of the mounting base 4 is an inverted door frame or inverted U-shaped high-strength frame structure. The horizontal connecting span at the top of the mounting base 4 spans directly below the rack unit 33 in a suspended manner. The quick-release plates 5 are vertically and symmetrically distributed on both sides of the vertical surface of the main structure of the mounting base 4. The hanging platforms 51 are right-angled stepped thickened flange structures that protrude horizontally inward. The horizontal lower surface of the hanging platform 51 forms a planar fit with the horizontal upper surface of the support plate 34. This design of the mounting base 4 as a symmetrical spanning structure with two... The design of the quick-release plate 5 with horizontal mounting plate 51 on the side allows the weight of the entire mounting base 4 and the reaction force on the push rod 41 to be distributed absolutely evenly on both sides of the support plate 34 at the lower end of the rack unit 33. By utilizing the large-area plane overlap between the mounting plate 51 and the support plate 34, not only is the mounting base 4 reliably supported and limited in the vertical direction of gravity, completely preventing the mounting base 4 from falling downward due to vibration, but the absolutely symmetrical and equal force distribution on both sides can also eliminate the lateral swaying or torsion caused by the off-center load. The quick-release plate 5 is also movably fitted with a locking tooth 6 that connects to the rack unit 33. After the mounting plate 51 overlaps the support plate 34, the locking tooth 6 is inserted along the tooth groove of the rack unit 33 to limit the quick-release plate 5 along the length direction of the rack unit 33. The main body of the locking tooth 6 is a vertically arranged metal insert-like structure. The side wall of the locking tooth 6 facing the rack unit 33 is machined with a vertical convex tooth profile that perfectly matches the shape, depth, and tooth pitch of the tooth groove of the rack unit 33. The quick-release plate 5 is correspondingly provided with a precise guide groove for the locking tooth 6 to slide vertically up and down. When it is necessary to fix or lock the quick-release plate 5, the locking tooth 6 slides along the guide groove. The groove moves vertically downwards, and the convex tooth profile on its side wall can mesh and embed into the deepest part of the tooth groove on the side of the rack unit 33. Using the original standard transmission tooth profile clearance of the rack unit 33 as a high-precision positioning reference in the horizontal direction, there is no need to open a special locking pin hole or positioning groove on the rack unit 33. This will not damage the original structural strength of the rack unit 33, and can achieve precise locking and positioning at any tooth pitch position along the length of the rack unit 33. Thus, the quick release plate 5 and the mounting base 4 connected to it can be infinitely and flexibly adjusted and shear-resistant mechanically limited in the transmission direction.

[0029] Please see Figures 1-8Each transmission rack 3 has a connecting plate 35 integrally formed at the mating surface of the two sets of rack units 33. The thickness of the connecting plate 35 is less than the thickness of the rack unit 33. The upper and lower end faces of the connecting plate 35 form two sets of toothed grooves extending along the length of the transmission rack 3 between the upper and lower end faces and the rack units 33 on both sides, respectively. The formed toothed grooves can greatly reduce the vibration of the transmission rack 3 during movement. The connecting plate 35 is a long strip-shaped thin plate structure that runs through the whole and is positioned on the geometric center line of the width dimension of the two sets of rack units 33. Due to the small thickness of the connecting plate 35, the toothed grooves formed by the inward clearance at the upper and lower ends leave ample air inside. The flow-through pressure channel and the material elastic deformation buffer allowance, when the external drive component and the transmission rack 3 are mechanically rigidly meshed, these two sets of end-to-end toothed grooves can serve as effective stress release isolation areas. They can not only absorb and block the propagation of sound waves generated by tooth surface impact, but also cut off the solid transmission path of high-frequency mechanical vibration. Thus, while ensuring the overall bending strength of the transmission rack 3, the overall structural weight of the transmission rack 3 is effectively reduced and the operating load of the external drive motor is reduced. Furthermore, through the acoustic damping and mechanical barrier effect of the internal cavity structure, the resonance noise and hard impact vibration in the assembly line transmission process are effectively reduced. The two rack units 33 of each transmission rack 3 are fixedly connected, and the slot 31 and the buckle 32 are respectively machined at both ends of the rack unit 33. The buckle 32 is a dovetail-shaped protrusion structure with a beveled front end or a cylindrical pin head with an anti-dislodgement barb structure. The slot 31 is a concave blind hole or a sliding groove structure that complements the outer contour of the buckle 32. The inner wall of the slot 31 is also provided with a corresponding closing limiting edge for the buckle 32 to slide in with interference and experience slight elastic locking. When adjacent transmission racks 3 are assembled end to end, the buckle 32 moves along the... The fixed opening direction of the slot 31 is forced in and immediately blocked by the closing limit edge, thus forming a firm mechanical self-locking fit that cannot be easily pulled out in the opposite direction. The slot 31 and the buckle 32 are respectively staggered at both ends of the rack unit 33 on both sides, so that the two sets of rack units 33 form a staggered overlapping and spatial cross-locking force form at the end splicing joint. This ensures that after the transmission rack 3 is connected into a full-length chain, when it is subjected to the alternating action of huge longitudinal tension and lateral thrust on the production line, the chain joint will not have the problem of longitudinal force pull-out or lateral twisting and disintegration.

[0030] Please see Figures 1-8The quick-release plate 5 has a fixing hole 52, and the side of the quick-release plate 5 also has a quick-release hole for fixing it to the mounting base 4. A bolt 8 is installed in the quick-release hole and fixedly connected to the mounting base 4. The fixing hole 52 is a circular through hole that penetrates the side wall of the quick-release plate 5. The inner wall of the hole is machined with a smooth transition fillet to avoid stress concentration. The quick-release hole is a countersunk hole structure. The bolt 8 is an internal hexagon countersunk bolt 8. The head of the bolt 8 is completely embedded in the countersunk hole and does not protrude outward. The structure design of using a countersunk hole and a countersunk bolt 8 can prevent the head of the bolt 8 from being exposed and scraping or colliding with the transmission rack 3 or other moving parts. At the same time, it ensures that the side of the quick-release plate 5 remains flat after being connected to the mounting base 4, and will not interfere with the movement stroke of surrounding parts. After the bolt 8 is tightened, the quick-release plate 5 and the mounting base 4 can be firmly connected into a whole. The fixing hole 52 is machined on the side of the quick-release plate 5. A wedge-shaped slider 61 with an inclined surface is coaxially slidably mounted on the snap-fit ​​teeth 6. The wedge-shaped slider 61 is inserted into the fixing hole 52, and the inclined surface is set on the lower end face of the wedge-shaped slider 61. The wedge-shaped slider 61 has a wedge-shaped block structure that is narrow at the front end and wide at the rear end. The inclined surface is a smooth inclined surface that slopes smoothly from the bottom of the front end of the wedge-shaped slider 61 to the top of the rear end. The inclination angle of the inclined surface is set to an angle range that can automatically generate a horizontal component force when subjected to vertical compression. The width of the wedge-shaped slider 61 is adapted to the inner diameter of the fixing hole 52, so that the wedge-shaped slider 61 can be smoothly inserted into the fixing hole 52 without producing excessive lateral wobbling. The design of setting the inclined surface on the lower end face of the wedge-shaped slider 61 can automatically drive the wedge-shaped slider 61 to complete the horizontal retraction action by utilizing the vertical movement of the snap-fit ​​teeth 6 during the downward insertion process. A spring 62 connects the wedge-shaped slider 61 to the locking tooth 6. One end of the spring 62 is fixedly connected to the locking tooth 6, and the other end is fixedly connected to the wedge-shaped slider 61. The spring 62 is a cylindrical helical compression spring. The axis of the spring 62 is consistent with the sliding direction of the wedge-shaped slider 61. The outer diameter of the spring 62 is smaller than the inner diameter of the mounting groove at the tail of the wedge-shaped slider 61. The use of a cylindrical helical compression spring 62 can provide a stable and continuous return force for the wedge-shaped slider 61, ensuring that the wedge-shaped slider 61 can pop out and lock in time when it moves to the corresponding position of the fixing hole 52. At the same time, the internal design of the spring 62 can prevent the spring 62 from being contaminated by external debris or damaged by external impacts. When the snap-fit ​​tooth 6 is inserted vertically downward into the tooth groove of the rack unit 33, the upper end face of the quick release plate 5 presses the wedge slider 61 to slide towards the snap-fit ​​tooth 6 and compresses the spring 62. When the wedge slider 61 moves vertically downward to the position of the fixing hole 52, the spring 62 resets and pushes the wedge slider 61 to be inserted into the fixing hole 52.During the downward insertion of the locking tooth 6, the inclined surface of the wedge-shaped slider 61 remains in contact with the upper end face of the quick-release plate 5. As the locking tooth 6 continues to move downward, the wedge-shaped slider 61 is continuously squeezed and remains in a contracted state until the front end face of the wedge-shaped slider 61 is aligned with the opening end face of the fixing hole 52. At this point, the squeezing force disappears, and the spring 62 releases its elastic potential energy to push the wedge-shaped slider 61 outward. After the wedge-shaped slider 61 is inserted into the fixing hole 52, its upper and lower end faces are tightly fitted with the upper and lower inner walls of the fixing hole 52, which can effectively restrict the movement of the locking tooth 6 in the vertical direction and prevent the locking tooth 6 from coming out of the tooth groove due to vibration during equipment operation. This achieves automatic anti-disengagement locking of the locking tooth 6. The entire locking process is completed automatically by structural cooperation without the need for additional manual locking operations.

[0031] Please see Figures 1-8A sliding groove 11 is machined below the support frame 1, and the support plate 34 at the upper end of the rack unit 33 is slidably connected to the sliding groove 11. The sliding groove 11 is an elongated groove structure with an opening facing downwards. The inner walls on both sides of the groove are machined with a smooth, wear-resistant coating. The internal width of the sliding groove 11 is slightly larger than the width of the support plate 34. A small gap is left between the two sides of the support plate 34 and the two sides of the inner walls of the sliding groove 11. This gap ensures that the support plate 34 slides smoothly inside the sliding groove 11 without getting stuck, and also allows the side walls of the sliding groove 11 to laterally limit the support plate 34, preventing lateral displacement of the support plate 34 during sliding. Sufficient clearance is left between the top inner wall of the sliding groove 11 and the upper surface of the support plate 34 to avoid frictional resistance between the support plate 34 and the top of the sliding groove 11 during sliding. The support frame 1 is also fixedly mounted with two or more sets of drive gears 13 that mesh with the single-sided rack unit 33 of the transmission rack 3. A drive motor is connected above the drive gears 13 and is fixedly mounted on the support frame 1. The tooth profile parameters of the drive gears 13 match the tooth profile parameters of the rack unit 33. Multiple sets of drive gears 13 are evenly spaced along the length of the support frame 1. The pitch circle tangents of all drive gears 13 are parallel to the movement direction of the transmission rack 3. The design of synchronous meshing transmission of multiple sets of drive gears 13 can evenly distribute the driving torque to multiple meshing points of the transmission rack 3, avoiding tooth surface wear or deformation caused by excessive force on a single set of gears. At the same time, multi-point drive can ensure that the force on the transmission rack 3 is more uniform during operation, effectively improving the smoothness of transmission. The drive motor is a geared motor, which can output a large enough torque to drive the entire transmission rack 3 and the suspended garment load to operate stably. Two or more sets of pulleys 12 are rotatably connected at equal intervals along the length of the support frame 1 within the sliding groove 11. The support plate 34 is slidably connected to the pulleys 12. The pulleys 12 are rotatably mounted between the inner walls of both sides of the sliding groove 11 via pins. The axis of the pulleys 12 is perpendicular to the direction of movement of the transmission rack 3. The outer circumferential surface of the pulleys 12 is machined with a smooth arc-shaped contact surface that matches the lower end face of the support plate 34. The highest point of the pulleys 12 is slightly higher than the bottom inner wall of the sliding groove 11, so that the support plate 34 is completely placed on the outer circumferential surface of the pulleys 12 without contacting the bottom inner wall of the sliding groove 11. The structure of rolling support by the pulleys 12 can convert the sliding friction between the support plate 34 and the sliding groove 11 into the rolling friction of the pulleys 12, which greatly reduces the frictional resistance in the transmission process and reduces the load energy consumption of the drive motor. A hanger wheel 21 is slidably mounted on the track 2. A hanger is mounted rotatably below the hanger wheel 21. When the mounting base 4 moves with the transmission rack 3, the push rod 41 pushes the hanger wheel 21 to slide along the track 2. One side of the locking teeth 6 on both sides of the mounting base 4 has a double tooth structure, and the other side has a single tooth structure.

[0032] Please see Figures 1-8During device operation, the drive motor rotates the drive gear 13, which meshes with one side rack unit 33 of the transmission rack 3. This drives the transmission rack 3, which is spliced ​​end to end, to slide along the pulley 12 in the sliding groove 11 below the support frame 1 via the support plate 34 at its upper end. When the transmission rack 3 is displaced, the mounting seat 4 mounted on the support plate 34 at the lower end of the rack unit 33 moves synchronously. The push rod 41 on the mounting seat 4 then pushes the hanger wheel 21, which is slidably mounted on the track 2, to move along the track 2, completing the assembly line hanging and transportation of hangers and garments. When assembling or adjusting the position of the mounting seat 4, firstly, the hanging platform 51 on the inner side of the quick-release plate 5 mounted on both sides of the mounting seat 4 is placed on the support plate 34 at the lower end of the rack unit 33; then, the snap-fit ​​teeth 6 are inserted vertically downward into the tooth groove of the rack unit 33 to limit the movement of the quick-release plate 5 along the length of the rack unit 33. During the downward insertion of the locking teeth 6, the upper end face of the quick-release plate 5 will press against the inclined surface of the lower end face of the wedge slider 61, forcing the wedge slider 61 to overcome the resistance and slide towards the locking teeth 6, while simultaneously compressing the spring 62; when the locking teeth 6 continue to press down, causing the wedge slider 61 to move vertically downward to the position of the fixing hole 52 on the side of the quick-release plate 5, the wedge slider 61 loses the pressure restriction of the end face of the quick-release plate 5, the compressed spring 62 automatically resets and pushes the wedge slider 61 into the fixing hole 52, completing the anti-disengagement locking of the locking teeth 6, thereby realizing the quick tool-free disassembly and assembly and stable connection of the mounting base 4 on the transmission rack 3.

[0033] Please see Figures 1-8 When a single transmission rack 3 in a chain of racks 3 connected end to end malfunctions and needs replacement, the mounting base 4 is first quickly disassembled. The operator presses the wedge-shaped slider 61 located in the fixing hole 52 on the side of the quick-release plate 5 inward, causing it to overcome the spring force of the spring 62 and exit the fixing hole 52 to release the locking state of the locking tooth 6. Then, the locking tooth 6 is pulled out from the tooth groove of the rack unit 33 in a vertically upward direction, and the quick-release plate 5 is removed from the support plate 34 at the lower end of the rack unit 33 using bolts 8. Then, for the faulty single transmission rack 3, its two ends are connected to the adjacent transmission rack 3. Once the buckle 32 disengages from the corresponding slot 31 and releases the engagement, the faulty transmission rack 3 can be independently extracted and removed. Then, a brand new transmission rack 3 is taken, and the slots 31 and buckles 32 machined at both ends are re-aligned and engaged with the buckles 32 and slots 31 at the ends of the two adjacent transmission racks 3 in the track 2 to restore the transmission chain connection. Finally, the removed mounting base 4 is reattached to the support plate 34 at the lower end of the brand new transmission rack 3 via the hanging platform 51 on the quick-release plate 5, and the locking teeth 6 are pressed down so that the wedge-shaped slider 61 is squeezed and automatically springs back into the fixing hole 52 to complete the locking and positioning.

[0034] Example 2 Please see Figures 9-12 A fixing hole 52 is machined on the upper end face of the quick-release plate 5. A fixing shaft 7 is coaxially fixed inside the fixing hole 52. An annular limiting platform 71 with a notch 72 is coaxially sleeved on the fixing shaft 7. The fixing hole 52 is a circular blind hole with anti-slip texture on the inner wall. The lower end of the fixing shaft 7 is press-fitted or integrally formed inside the fixing hole 52. The fixing shaft 7 is perpendicular to the upper end face of the quick-release plate 5. The notch 72 of the annular limiting platform 71 is a through groove that penetrates the side wall of the limiting platform 71 radially. The side wall of the notch 72 is smoothly transitioned. A cam 73 is eccentrically and rotatably sleeved on the outer periphery of the fixing shaft 7. Stepped blocks 74, which are distributed in a spiral stepped array along the axial direction and whose size corresponds to the notch 72, protrude from the inner wall of the shaft hole of the cam 73. The outer peripheral surface of the cam 73 abuts against the tooth surface of the transmission rack 3 and forms a friction transmission engagement. The inner diameter of the shaft hole of cam 73 is larger than the outer diameter of fixed shaft 7, and a uniform rotational clearance is left between the two to ensure that cam 73 can rotate smoothly. The outer contour of stepped block 74 is adapted to or slightly smaller than the inner contour of notch 72. The eccentric sleeve structure can ensure that the outer peripheral surface of cam 73 and the tooth surface of transmission rack 3 always keep in close contact during the rotation of cam 73. As quick release plate 5 moves along transmission rack 3 with mounting base 4, transmission rack 3 drives cam 73 to rotate. Whenever stepped block 74, which is connected to limit platform 71, rotates to the position of notch 72, stepped block 74 passes through notch 72 axially and causes cam 73 to descend axially. When the topmost stepped block 74 falls and gets stuck in notch 72, cam 73 is circumferentially limited and stops rotating. At this time, the convex end of cam 73 is wedged with transmission rack 3 to restrict quick release plate 5 from continuing to move. After the top step block 74 is inserted into the notch 72, the side wall of the step block 74 fits tightly with the side wall of the notch 72, completely restricting the circumferential rotational freedom of the cam 73. At this time, the convex end of the cam 73 forms an interference fit with the tooth groove side wall of the transmission rack 3, and the resulting wedge force can restrict the movement of the quick release plate 5 along the length direction of the transmission rack 3.

[0035] Please see Figures 9-12During installation, the lowest step block 74 of the cam 73 is installed along the position direction of the notch 72. When the highest step block 74 falls and engages with the notch 72, the number of teeth that the cam 73 moves on the transmission rack 3 is equal to the number of teeth between the two sets of mounting seats 4 on the transmission rack 3. Aligning the lowest step block 74 with the notch 72 during initial installation ensures a correspondence between the starting position and the ending position of the cam 73's rotation, guaranteeing a fixed ratio between the total number of rotations of the cam 73 and the number of teeth moved on the transmission rack 3. This installation method eliminates initial positional errors during the cam 73 assembly process, ensuring that the spacing of all mounting seats 4 is completely consistent after adjustment, preventing any deviation in the spacing of individual mounting seats 4. The specific number and spacing of the step blocks 74 within the cam 73's shaft hole are determined based on the number of teeth between the two sets of mounting seats 4 on the transmission rack 3. The axial spacing of the step blocks 74 corresponds to the number of teeth that the cam 73 moves along the transmission rack 3 for each revolution. By adjusting the number of step blocks 74, different installation spacing requirements can be met. There is no need to replace the cam 73 or other parts. Only the arrangement of the step blocks 74 needs to be adjusted to meet the spacing requirements of the push rods 41 when producing garments of different sizes, which greatly improves the versatility and adaptability of the device.

[0036] Please see Figures 9-12The diameter of the limiting platform 71 is larger than the inner diameter of the stepped block 74, and the limiting platform 71 is detachably connected to the fixed shaft 7. When the last set of stepped blocks 74 falls into the notch 72, the bottom surface of the stepped block 74 abuts against the bottom surface of the notch 72 and its top surface is coplanar with the top surface of the limiting platform 71, thereby completely limiting the cam 73 in the axial and circumferential directions; the lowest stepped block 74 is positioned higher than the bottom end face of the cam 73. The limiting platform 71 and the fixed shaft 7 can be quickly assembled and disassembled using threaded engagement or elastic snap-fit. The structure of the limiting platform 71, with a diameter larger than the inner diameter of the stepped block 74, provides stable axial support for all stepped blocks 74 that are not aligned with the notch 72, preventing the cam 73 from falling uncontrollably downwards during rotation. This ensures that the cam 73 can only complete its step-by-step descent when the stepped block 74 is aligned with the notch 72. The detachable design of the limiting platform 71 allows for quick removal of the cam 73 by simply removing the limiting platform 71 from the fixed shaft 7 when the mounting base 4 needs to be reset, without disassembling other connecting structures. The surface of the cam 73 is provided with an anti-slip texture layer. The anti-slip texture layer is a fine knurled or frosted structure evenly distributed on the outer circumference of the cam 73, increasing the friction coefficient between the cam 73 and the tooth surface of the transmission rack 3, preventing the cam 73 from slipping and spinning freely during transmission. The interference fit generates sufficient static friction after wedging, completely restricting the movement of the quick-release plate 5, preventing displacement even if vibration occurs during equipment operation. When the convex end of cam 73 is wedged tightly with the transmission rack 3, the tooth surfaces of cam 73 and transmission rack 3 are in an interference fit; the bottom surface of fixing hole 52 is lower than the top surface of the platform and higher than its bottom surface. Engineering plastics, polyurethane or modified rubber materials with a certain elastic deformation capability can be selected. The flexible material step block 74 can produce a small elastic deformation when it contacts the side wall of notch 72. On the one hand, it can fill the assembly gap between step block 74 and notch 72, ensuring that the circumferential limit is more secure and will not loosen or shake. On the other hand, it can absorb the mechanical vibration generated during the operation of the equipment, dissipate the vibration energy through elastic deformation, and prevent the vibration from being transmitted to the mounting base 4, causing the push rod 41 to be pushed off the position. At the same time, the flexible material can reduce the wear of step block 74 during the contact process with limit platform 71. Quick release plates 5 are respectively installed on both sides of mounting base 4. A single fixed shaft 7 is provided on the quick release plate 5 on one side of mounting base 4, and two fixed shafts 7 are spaced apart along the length direction of transmission rack 3 on the quick release plate 5 on the other side of mounting base 4.

[0037] Please see Figures 9-12Example 2 primarily utilizes a friction drive and mechanical limit linkage mechanism to achieve automatic and precise control of the installation spacing of the mounting seats 4. When adjusting the installation spacing of adjacent mounting seats 4, the cam 73 is coaxially mounted on the fixed shaft 7, with its lowest step block 74 abutting against the notch 72 of the limiting platform 71. Then, external force is used to push the mounting seat 4, causing the quick-release plate 5 to move along the transmission rack 3. Because the outer circumferential surface of the cam 73 abuts against the tooth surface of the transmission rack 3, forming a friction drive engagement, the transmission rack 3 drives the cam 73, eccentrically mounted on the fixed shaft 7, to rotate during relative movement through static friction. During the rotation of the cam 73, the step blocks 74, arranged in a spiral step array along the axial direction on the inner wall of its shaft hole, rotate accordingly. Whenever the lowest step block 74, which overlaps with the limiting platform 71, rotates to the notch 72 position of the limiting platform 71, the step block 74 loses axial support and, under the influence of gravity, passes through the notch 72 axially, causing the entire cam 73 to descend axially. As the quick-release plate 5 continues to move, the cam 73 continues to rotate and descend step by step. When the quick-release plate 5 moves to the set target interval position, the number of teeth that the cam 73 has moved on the transmission rack 3 is exactly equal to the number of teeth between the two sets of mounting seats 4, and the topmost step block 74 falls and locks into the notch 72, thus completely limiting the cam 73 in the axial and circumferential directions, forcing the cam 73 to stop rotating immediately. At the same time that the cam 73 stops rotating due to its eccentric structure and the anti-slip texture layer on its surface, the cam 73's convex end rotates to a state of wedging tightly with the transmission rack 3, forming an interference fit. The resulting resistance further restricts the quick-release plate 5 from continuing to move, thus achieving automatic positioning and locking of the spacing without manual counting of teeth. When it is necessary to disassemble, replace, maintain, or readjust the initial position of the mounting base 4, first remove the limiting platform 71, which is detachably connected to the fixed shaft 7, from the fixed shaft 7. Release the axial blocking limitation of the limiting platform 71 on the cam 73. Then, the operator can directly pull the cam 73 outward along the axial direction of the fixed shaft 7 and completely separate it from the fixed shaft 7. At this time, the convex end of the cam 73 is released from the interference wedge self-locking state between it and the tooth surface of the transmission rack 3, so that the quick release plate 5 regains its freedom in the axial and circumferential directions. Then, move the quick release plate 5 upward or to the side so that the hanging platform 51 on the inner side of the quick release plate 5 is disengaged from the overlapping state of the lower end support plate 34 of the transmission rack 3. The entire mounting base 4, together with the quick release plate 5 and the fixed shaft 7, can be completely removed from the transmission rack 3, completing the overall disassembly.

[0038] Please see Figures 9-12When the mounting base 4 runs along the track 2 with the transmission rack 3, the mechanical vibration generated by the meshing of the gear and the transmission rack 3 and the friction of the track 2 is transmitted upward to the fixed shaft 7. Since multiple sets of stepped blocks 74 made of flexible material are spirally arrayed on the inner wall of the shaft hole of the cam 73, the inner side of the multiple sets of stepped blocks 74 sleeved on the fixed shaft 7 forms a multi-point abutment and fit connection with the outer peripheral surface of the fixed shaft 7. During vibration transmission, the multi-point contact structure first evenly distributes the vibration stress concentrated on the fixed shaft 7 to the contact points between each stepped block 74 and the fixed shaft 7. Then, the stepped block 74 at each contact point undergoes slight elastic deformation, thereby absorbing, dissipating and buffering a large amount of rigid impact kinetic energy during transmission. This is equivalent to setting up a flexible damping strip between the fixed shaft 7 and the cam 73, avoiding the vibration concentration and amplification effect that is easily caused by traditional single rigid contact points. In this way, while significantly reducing the mechanical vibration of the mounting base 4 and ensuring the extreme stability of the clothes hanger and garment hanging and transportation, it fundamentally prevents the bolts 8 from loosening or metal fatigue caused by long-term high-frequency vibration of the overall structure, greatly improving the stability of equipment operation.
