Description

Technical Field

[0001] This utility model relates to the technical field of textile machine components, and in particular to a U-shaped protective bar for textile machines. Background Technology

[0002] Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., originated from ancient human-powered looms. The term "textile machine" encompasses all tools used to process raw materials such as thread, silk, and hemp into fabric, including spinning wheels, spindles, treadle looms, and modern mechanical looms and CNC automatic looms. The development of textile processes and equipment throughout history has been designed in response to the availability of textile raw materials; therefore, raw materials hold a crucial position in textile technology. In ancient times, the fibers used for textiles in various countries were all natural fibers, generally consisting of three short fibers: wool, hemp, and cotton.

[0003] In the operation of existing textile machines, traditional guard bars lack a buffering mechanism. When operators or external objects accidentally impact the machine, the impact force is directly transmitted to the frame, which can easily lead to deformation of the guard bar or damage to the frame structure. Long-term use may affect the accuracy of the equipment, and people may also be entangled in the textile machine, posing certain safety hazards. Some movable guard bars cannot automatically reset after being subjected to external force, requiring manual intervention and adjustment, which reduces operating efficiency. The closing and positioning of existing guard bars mostly rely on simple buckles or bolts, which are prone to loosening due to vibration after closing. Opening and closing operations are also cumbersome. The guard bars lack a guiding design during movement, making them prone to deviation or jamming. At the same time, the linkage efficiency between the buffer components and the guard bars is low, and the energy absorption effect is limited. Summary of the Invention

[0004] This utility model is proposed to address the shortcomings of existing technologies, such as rigid collision problems, insufficient rebound function, poor positioning stability, and defects in guidance and linkage. It provides a U-shaped protective bar for textile machines, which protects the front of the human body and prevents the entire body from being pulled into the fabric of the take-up roller when leaning forward, thus avoiding danger. The connection position has a buffer that can be pressed down and has a rebound effect to avoid compression of the chest due to prolonged pressure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A U-shaped protective bar for a textile machine includes a textile machine frame. A connector is rotatably connected to one side of the textile machine frame, and a protective bar for shielding and protecting the textile machine frame is rotatably sleeved on the outside of the connector. A buffer part is provided between the protective bar and the textile machine frame to facilitate the rebound of the protective bar. The buffer part includes a pressing component and a buffer component. Both the pressing component and the buffer component are provided on one side of the textile machine frame, and the buffer component is located below the pressing component.

[0007] With the above technical solution, when the guard bar flips, the guard bar itself squeezes the pressing component, and the pressing component, together with the buffer component, provides a rebound buffer function for the guard bar. At the same time, the guard bar can provide a shielding and protective function.

[0008] Preferably, the pressing assembly includes a fixing plate disposed on one side of the textile machine frame. A bolt is threadedly connected to one side of the fixing plate, and a guide sleeve is disposed on one side of the fixing plate. A guide rod is slidably connected to the inner side of the guide sleeve, and a pressing block is disposed on the lower side of the guide rod.

[0009] Through the above technical solution, the protective rod flips down and presses down the guide rod. The guide rod moves inside the guide sleeve, and the guide rod drives the pressing block to move down, thereby providing a guiding and pressing function.

[0010] Preferably, the buffer assembly includes a connecting frame disposed on one side of the textile machine frame. Two bolts are threadedly connected to one side of the connecting frame. A connecting block is disposed on one side of the connecting frame. A connecting rod is disposed on one side of the connecting block. A torsion spring is disposed between the connecting rod and the connecting block. A buffer strip is disposed at one end of the connecting rod. One side of the buffer strip abuts against one side of the lower pressure block.

[0011] Through the above technical solution, the lower pressure block moves and pushes the buffer strip, which drives the connecting rod to rotate on the connecting block, thereby compressing the torsion spring and using the rebound force of the torsion spring to provide a buffering and rebound function for the lower pressure block.

[0012] Preferably, a guide assembly is provided on one side of the textile machine frame and below the guard rod. The guide assembly includes a mounting block, which is located on one side of the textile machine frame. A guide wheel is provided on the upper side of the mounting block, and one side of the guide wheel abuts against one side of the guard rod.

[0013] Through the above technical solution, the guide wheel can provide a flipping guide function for the protective rod.

[0014] Preferably, a positioning component is provided on one side of the textile machine frame and above the guard rod. The positioning component includes a positioning frame, a magnetic suction component, a first blocking component, and a second blocking component. The positioning frame is located on one side of the textile machine frame, and a magnetic suction component is provided on the inner side of the positioning frame. The first blocking component and the second blocking component are respectively provided on one side of the positioning frame.

[0015] Preferably, the first shielding component includes a push plate, which is slidably connected to one side of the positioning frame. A movable plate is provided on one side of the push plate, and a plurality of tension springs are provided on one side of the movable plate. One end of each tension spring is fixedly connected to one side of the positioning frame.

[0016] Preferably, the second shielding component includes a second push plate, which is inserted into one side of the textile machine frame, and a plurality of springs are provided on one side of the second push plate.

[0017] Through the above technical solution, the protective rod flips into the positioning frame. First, the magnetic component is used to magnetically attract the protective rod, and then the shielding component one and the shielding component two provide a shielding function for the protective rod.

[0018] In summary, when the protective bar flips over, it presses against the pressing component, which, together with the buffer component, provides a rebound buffering function for the protective bar. At the same time, the protective bar provides a shielding and protective function.

[0019] When the protective rod of this utility model is flipped, the protective rod flips down and presses down the guide rod. The guide rod moves inside the guide sleeve, and the guide rod drives the pressing block to move down. The moving pressing block pushes the buffer strip, and the buffer strip drives the connecting rod to rotate on the connecting block, thereby squeezing the torsion spring. The rebound force of the torsion spring provides a buffering and rebound function for the pressing block.

[0020] This utility model employs a coordinated design of a pressure-down component and a buffer component in the buffer section. When the protective rod is impacted by an external force, the pressure-down block pushes the buffer bar, and the torsion spring absorbs the impact energy and automatically resets, effectively reducing the damage to the frame caused by rigid collisions and extending the service life of the equipment. The torsion spring in the buffer component has a compact structure and stable rebound, and compared with the traditional spring buffer method, it has higher durability and reliability.

[0021] In this invention, the guide assembly ensures smooth movement of the guard rod during opening and closing by the rolling contact between the guide wheel and the guard rod, avoiding deviation or jamming and improving operational smoothness. The sliding cooperation between the guide sleeve and the guide rod further enhances the movement stability of the guard rod and prevents shaking caused by vibration or external force.

[0022] In this invention, the positioning component adopts a combination design of magnetic suction component and shielding component one and shielding component two. When the protective rod is closed, it can be quickly fixed by magnetic attraction. At the same time, push plate one and push plate two provide auxiliary locking under the action of tension spring and spring, preventing the protective rod from being opened accidentally due to mechanical vibration. The shielding component adopts an elastic reset structure, which makes the opening and closing of the protective rod more effortless and improves the operating efficiency.

[0023] This utility model features a U-shaped protective rod with a wide coverage area, effectively preventing operators from accidentally touching high-speed rotating parts and reducing the risk of workplace injuries. The combination of the buffer and guide components allows the protective rod to effectively absorb energy and automatically reset when subjected to impact, preventing protection failure due to external forces.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] like Figure 1-6 As shown, a U-shaped protective bar for a textile machine includes a textile machine frame 1, a connector 2, a protective bar 3, a buffer part 4, a guide assembly 5, and a positioning assembly 6.

[0033] One side of the textile machine frame 1 is fixed to the connecting piece 2 by bolts or welding. The connecting piece 2 adopts a bearing or hinge structure, so that the protective rod 3 can rotate around it. The protective rod 3 has a U-shaped structure and its surface is frosted. The protective rod 3 is sleeved on the outside of the connecting piece 2 and can rotate along the connecting piece 2 to achieve shielding and protection of the textile machine frame 1.

[0034] The buffer part 4 includes a pressing component 41 and a buffer component 42, both of which are installed on the same side of the textile frame 1. The buffer component 42 is located below the pressing component 41. When the protective rod 3 is impacted by an external force, it will drive the pressing component 41 to move, thereby triggering the buffer component 42 to absorb the impact energy and automatically reset after the external force disappears.

[0035] The pressing assembly 41 includes a fixed plate 411, a guide sleeve 413, a guide rod 414, and a pressing block 415. The fixed plate 411 is fixed to the textile machine frame 1 by bolts 412 for easy disassembly and maintenance. The guide sleeve 413 is welded or bolted to one side of the fixed plate 411 and has a sliding cavity inside. The guide rod 414 is slidably connected in the guide sleeve 413 and can move up and down in the vertical direction. The pressing block 415 is fixed to the lower end of the guide rod 414 and is used to contact the buffer assembly 42.

[0036] When the protective rod 3 is pressed inward by an external force, it pushes the guide rod 414 to slide downward, causing the lower pressure block 415 to squeeze the buffer assembly 42, thereby achieving a buffering effect.

[0037] The buffer assembly 42 includes a connecting frame 421, a connecting block 423, a torsion spring 425, and a buffer strip 426. The connecting frame 421 is fixed to the textile machine frame 1 by bolts 422. The connecting block 423 is fixed to the connecting frame 421. The connecting rod 424 is hinged to it by a pivot. The torsion spring 425 is sleeved on the pivot of the connecting rod 424 to provide a rebound force. The buffer strip 426 is fixed to the end of the connecting rod 424 and contacts the lower pressure block 415.

[0038] When the pressure block 415 moves downward, it squeezes the buffer strip 426, causing the connecting rod 424 to rotate around the pivot, and the torsion spring 425 is compressed and stores energy; after the external force disappears, the torsion spring 425 releases its elastic force, pushing the buffer strip 426 to reset, so that the protective rod 3 returns to its original position.

[0039] The guide assembly 5 includes a mounting block and a guide wheel. The mounting block is fixed on the textile frame 1 and located below the guard rod 3. The guide wheel is mounted on the mounting block and makes rolling contact with the side of the guard rod 3.

[0040] During the opening and closing process, the guide wheel of the protective rod 3 reduces friction, ensuring smooth movement and preventing jamming.

[0041] The positioning component 6 includes a positioning frame 61, a magnetic suction component 62, a first shielding component 63, and a second shielding component 64. The positioning frame 61 is located on one side of the textile machine frame 1. The magnetic suction component 62 is embedded inside the positioning frame 61 and is used to attract the metal part of the protective rod 3 to achieve quick closure and fixation. The first shielding component 63 and the second shielding component 64 are respectively located on one side of the positioning frame 61.

[0042] The shielding component 63 includes a push plate 631, a movable plate 632, and a tension spring 633. The push plate 631 is slidably connected to the positioning frame 61 and can move laterally. The movable plate 632 is connected to the push plate 631. One end of the tension spring 633 is fixedly connected to one side of the positioning frame 61. The tension spring 633 is used to provide a reset pulling force so that the push plate 631 automatically locks when the protective rod 3 is closed.

[0043] The second shielding component 64 includes a second push plate 641 and a spring 642. The second push plate 641 is inserted into the textile machine frame 1, and the spring 642 is provided inside to provide elastic support and enhance the closing stability.

[0044] When the protective rod 3 is closed, it is first attracted and fixed by the magnetic 62, and then the push plate 631 and the push plate 641 are further locked under the action of the spring to prevent vibration from causing loosening.

[0045] Normal closed state: The protective rod 3 is fixed by the magnetic 62 and the shielding component 1 63 and the shielding component 2 64 to ensure stable closure.

[0046] When subjected to external impact: the protective rod 3 moves inward, and the pressing component 41 pushes the buffer component 42 to absorb the impact and avoid rigid collision.

[0047] After the external force disappears: the torsion spring 425 rebounds, causing the protective rod 3 to automatically return to its original position, and the guide wheel ensures smooth movement.

[0048] Opening procedure: Manually pull the protective rod 3 outward to overcome the magnetic attraction and spring force to easily open.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
