Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to a textile cross chain connector. Background Technology

[0002] A cross chain in textile machinery is a chain device used to transmit power or motion laterally. It is typically made of metal or high-strength polymer, possessing wear-resistant and tensile-resistant properties. Its core function is to connect power between different drive shafts, making it particularly suitable for scenarios requiring changes in transmission direction (such as vertical to horizontal) or multi-point synchronous drive (such as heald frame lifting in a loom). The cross chain achieves precise motion transmission through meshing gear sets and can be equipped with a speed-changing mechanism to adjust the speed. Compared to traditional belt drives, cross chains offer higher rigidity and synchronization, reducing slippage errors and improving the uniformity and production efficiency of textiles. They are commonly found in modern high-speed looms, warp knitting machines, and other equipment.

[0003] A search revealed patent publication number CN203272348U, which discloses a textile machine connector, including a base plate. The connector is characterized by further including a sloping groove, a connecting block, and reinforcing ribs. The base plate has a sloping groove in its center with sloping holes, and reinforcing ribs. A connecting block protrudes from one side of the base plate along its width, and has mounting holes. This invention solves the problems of existing textile machine connectors, which are complex in structure, inconvenient to install, and require tilting connections between components. Using conventional openings makes proper connection difficult. Furthermore, the connectors are often weak and easily damaged, leading to connection failures and unusable textile machines, causing significant disruption to production. This invention provides a textile machine connector with a simple structure, convenient connection, high strength, durability, and long service life.

[0004] While existing technologies can achieve a certain effect in installing textile cross chains, they suffer from the drawback of lacking convenient cross chain connection structures on the surface of existing textile devices. This results in poor cross chain installation and affects rotation controllability. In view of this, we propose a textile cross chain connector that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a textile cross-chain connector.

[0006] The technical solution of this utility model is as follows: A textile cross-chain connector includes a mounting frame, a movable block, a mounting post, and a rotating block. The upper end of the mounting frame is provided with a symmetrically designed guide rail. The movable block is provided inside the guide rail. The upper end of the movable block is fixed with a mounting post. Gear three, gear two, and gear one are rotatably mounted on the outer wall of the mounting post from bottom to top. The upper end of the mounting post is rotatably mounted with a rotating block.

[0007] When using this device, the mounting bracket is fixed to the upper end of the textile machinery with screws through the clips, serving as a transfer and receiving mechanism. It primarily provides multi-functional connection for horizontal chains but does not offer speed regulation. The position of the moving block is first adjusted using a servo motor, and then the horizontal chain is installed on the corresponding gears. If only the transmission angle needs to be changed, the horizontal chain is simply installed on one set of gears, and the other crossbeams are installed on different gears in the same set, achieving the angle conversion effect. To achieve speed regulation, the crossbeams on both sides are installed on different gear sets, and an elastic chain is installed between the gear sets. This allows one set of gears to transmit torque to the other, and different speeds can be achieved by using gears from different sets. This device offers convenient connection of horizontal chains and speed regulation for horizontal chain conveying, making it highly practical.

[0008] Preferably, a separating ring is provided between the gear three and the upper surface of the moving block to prevent direct frictional wear between the gear three and the moving block.

[0009] Preferably, a second separating ring is provided between gear three and gear two to isolate the axial force interference between gear two and gear three, and to ensure the torque transmission accuracy when multiple gears operate synchronously.

[0010] Preferably, a separator ring is provided between gear 2 and gear 1, and the number of teeth of gear 1, gear 2 and gear 3 gradually increases. The speed ratio gradient is formed by the increasing number of teeth of gear 1, 2 and 3, which, together with the elastic chain, achieves a predictable linear speed change effect.

[0011] Preferably, the guide rail has fixed seats on both sides inside, and a lead screw is rotatably installed between the fixed seats. The lead screw is threadedly connected to the moving block. A servo motor is fixed on the outer wall of one side of the fixed seat. The output shaft of the servo motor is fixedly connected to the rotation center of one side of the lead screw. The closed-loop control of the servo motor and the lead screw realizes millimeter-level positioning of the moving block and precise alignment of different gear sets.

[0012] Preferably, a slot is provided on one side of the rotating block, and limit keys are inserted through both sides of the slot. A spring is fixed between the cap of the limit key and the outer wall of the rotating block. The spring-tightened limit key can quickly lock the external connection port.

[0013] Preferably, the rotating block has a positioning hole on the other side, and a limit pin is fixed between the positioning holes. The outer walls of both sides of the mounting bracket have buckles, the limit pin allows for easy attachment of ropes to the surface, and the positioning hole facilitates the positioning of some control components.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model innovatively integrates lateral positioning, angle conversion and stepless speed change functions by using a moving block to drive an adjustable gear set and an elastic chain, thus solving the problems of rigid transmission layout and bulky speed change mechanism in traditional textile machinery.

[0016] Second, based on the first beneficial effect, the separator ring system improves the reliability of multi-gear coordination, the lead screw drive ensures adjustment accuracy, and the slot and positioning hole design optimizes connection stability and ease of operation. The device achieves highly compatible transmission transfer with a lightweight structure, significantly reducing equipment modification costs and energy consumption.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a textile cross-chain connector, including a mounting frame 1, a movable block 5, a mounting post 17 and a rotating block 20. The upper end of the mounting frame 1 is provided with a symmetrically designed guide rail 7. The movable block 5 is provided inside the guide rail 7. The upper end of the movable block 5 is fixed with the mounting post 17. The outer wall of the mounting post 17 is rotatably mounted with gear 3 11, gear 2 9 and gear 1 8 from bottom to top. The rotating block 20 is rotatably mounted on the upper end of the mounting post 17.

[0030] When using this device, the mounting bracket 1 is fixed to the upper end of the textile machinery with screws passing through the buckle 2, serving as a transfer and receiving mechanism. It primarily provides multi-functional connection for horizontal chains but does not offer speed regulation. The position of the moving block 5 is first adjusted using the servo motor 3, and then the horizontally placed chain is installed on the corresponding gear. If only the transmission angle needs to be changed, the horizontal chain is simply installed on one set of gears, and the other crossbeams are installed on different gears in the same set, achieving angle conversion. To achieve speed regulation, the crossbeams on both sides are installed on different gear sets, and an elastic chain is installed between the gear sets. This allows one set of gears to transmit torque to the other, and different speeds can be achieved by using gears on different gear sets. This device offers convenient connection of horizontal chains and speed regulation for horizontal chain conveying, making it highly practical.

[0031] Example 2

[0032] Please see Figures 1-4As shown, this embodiment, based on embodiment 1, further includes: a separating ring 12 between gear 3 11 and the upper surface of the moving block 5, to prevent direct frictional wear between gear 3 11 and the moving block 5, reduce vibration and noise during high-speed operation, and extend gear life.

[0033] A separator ring 2 10 is provided between gear 3 11 and gear 2 9 to isolate the axial force interference between gear 2 9 and gear 3 11, and to ensure the torque transmission accuracy when multiple gears operate synchronously.

[0034] A separator ring 13 is provided between gear 29 and gear 18. The number of teeth of gear 18, gear 29 and gear 31 gradually increases. The speed ratio gradient is formed by the increasing number of teeth of gear 18, 2 and 3. With the help of the elastic chain, a predictable linear speed change effect is achieved to adapt to the speed requirements of different textile processes.

[0035] The guide rail 7 has fixed seats 4 on both sides inside, and a lead screw 6 is rotatably installed between the fixed seats 4. The lead screw 6 is threadedly connected to the moving block 5. A servo motor 3 is fixed on the outer wall of one side of the fixed seat 4. The output shaft of the servo motor 3 is fixedly connected to the rotation center of the lead screw 6. The closed-loop control of the servo motor 3 and the lead screw 6 realizes the millimeter-level positioning of the moving block 5, accurately aligns different gear sets, avoids chain misalignment and fall off, and reduces the time spent on manual adjustment, thus providing a good function of bridging the crossbeam.

[0036] A slot 16 is provided on one side of the rotating block 20. Limit keys 15 are inserted through both sides inside the slot 16. A spring 14 is fixed between the cap of the limit key 15 and the outer wall of the rotating block 20. The limit key 15, which is pre-tightened by the spring 14, can quickly lock the external connection port. It can conveniently provide a fixed point when the textile device is installed, and has a good auxiliary effect.

[0037] The rotating block 20 has a positioning hole 18 on the other side, and a limit pin 19 is fixed between the positioning holes 18. Buckles 2 are provided on both outer walls of the mounting bracket 1. The limit pin 19 allows for easy attachment of ropes to the surface, and the positioning holes 18 facilitate the positioning of some control elements. This multi-functional design further highlights the transfer and receiving effect of this device.
