Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of belt looms, and more specifically, to a selvedge transmission mechanism for belt looms. Background Technology

[0002] In the textile industry, the production of ribbon fabrics relies heavily on the efficient operation of looms. The selvage drive mechanism of the loom plays a crucial role in ensuring the edge quality of ribbon fabrics. Currently, the selvage drive mechanisms widely used in the market have significant shortcomings in the connection method of the small shuttle.

[0003] In existing overlocking transmission mechanisms, the shuttle is typically connected to the transmission components through a complex connection method, such as using multiple fastening bolts or cumbersome nesting structures. When the shuttle needs to be installed or removed, operators often need to use various tools and spend a significant amount of time loosening or disassembling numerous connecting parts. Furthermore, when reinstalling the shuttle, careful and precise alignment of each component is required; even slight deviations can cause the shuttle to jam or shift during subsequent operation, severely affecting the overlocking quality. In addition, frequent installation and removal of these complex connecting parts easily leads to wear and tear, further increasing equipment maintenance costs and downtime. Therefore, there is an urgent need for a new overlocking transmission mechanism for belt looms to improve the shuttle connection method, enabling rapid installation and removal, improving production efficiency, and reducing maintenance costs. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a belt-type loom locking transmission mechanism, which solves the technical problem that in the prior art, when the small shuttle needs to be loaded and unloaded, operators often need to use a variety of tools and spend a lot of time loosening or disassembling numerous connecting parts, resulting in low efficiency and inconvenience.

[0005] According to one aspect, at least one embodiment of this disclosure provides a weft locking transmission mechanism for a belt-type loom, comprising:

[0006] A base frame and a linear guide rail, wherein the linear guide rail is disposed on the outside of the base frame;

[0007] The shuttle body and the drive connection assembly are provided. The shuttle body is mounted on the base frame, and the drive connection assembly is located between the shuttle body and the base frame.

[0008] A docking assembly is disposed between the linear guide rail and the base frame;

[0009] The drive connection assembly includes a moving block, which is connected to the base frame via a linear drive. The top of the moving block is provided with a positioning slot, and a mounting bracket is inserted into the positioning slot. The shuttle body is fixed to one end of the mounting bracket and is located in the linear guide rail.

[0010] As a further technical solution, the top of the mounting frame is provided with several anti-detachment blocks, and the top of the movable block is rotatably connected to a pressure plate via a pin. The surface of the pressure plate is provided with several sleeve openings, and the sleeve openings are all fitted onto the anti-detachment blocks.

[0011] As a further technical solution, a number of springs are connected between the pressure plate and the moving block, a support groove is provided on the upper end face of the base frame, and a notch is provided in the support groove, the notch corresponding to the position of the mounting frame.

[0012] As a further technical solution, the docking assembly includes a pair of lugs, which are respectively fixed to the upper and lower ends of the linear guide rail. Bolts are inserted into the lugs, and the bolts are connected to the base frame by threaded screwing.

[0013] As a further technical solution, a pair of sleeve blocks are provided on the side surface of the base frame, and a pair of locking blocks are provided on one side of the linear guide rail. The locking blocks are all inserted into the sleeve blocks. The sleeve blocks are U-shaped in shape, and the locking blocks are L-shaped in shape.

[0014] As a further technical solution, the anti-detachment block has a cylindrical structure, and the sleeve opening has a semi-circular opening structure.

[0015] As a further technical solution, the inner end face of the support groove is slidably attached to the bottom surface of the pressure plate.

[0016] As a further technical solution, one end of the pressure plate extends outward beyond the inner side of the base frame.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the drive connection assembly achieves rapid loading and unloading of the shuttle body through the insertion and mating of the positioning slot and the mounting bracket, as well as the elastic locking structure of the pressure plate and spring. Operators can unlock the mechanism simply by pressing the pressure plate, eliminating the cumbersome operation of disassembling numerous bolts required in traditional connection methods and significantly reducing shuttle replacement time. The elastic force of the spring ensures the mounting bracket is firmly fixed to the moving block, preventing the shuttle body from shaking or falling off during movement, ensuring the stability and accuracy of the overlocking operation. This solves the problems of low loading and unloading efficiency and inconvenient operation in existing technologies, improving the continuity and reliability of loom production.

[0030] like Figures 1-3 As shown, it illustrates a weft locking transmission mechanism for a belt-type loom according to an embodiment of the present disclosure, comprising:

[0031] The base frame 1 and the linear guide rail 2 are arranged on the outside of the base frame 1;

[0032] The shuttle body 3 and the drive connection component 4 are provided. The shuttle body 3 is mounted on the base frame 1, and the drive connection component 4 is mounted between the shuttle body 3 and the base frame 1.

[0033] A docking component 5 is disposed between the linear guide rail 2 and the base frame 1;

[0034] The drive connection assembly 4 includes a moving block 4-1, which is linearly driven and connected to the base frame 1. A positioning slot 4-2 is provided on the top of the moving block 4-1, and a mounting bracket 4-3 is inserted into the positioning slot 4-2. The shuttle body 3 is fixed to one end of the mounting bracket 4-3 and is located in the linear guide rail 2. Several anti-detachment blocks 4-4 are provided on the top of the mounting bracket 4-3. A pressure plate 4-5 is rotatably connected to the top of the moving block 4-1 via a pin. Several openings 4-6 are provided on the surface of the pressure plate 4-5, and each opening 4-6 is fitted onto one of the anti-detachment blocks 4-4. Several springs 4-7 are connected between the pressure plate 4-5 and the moving block 4-1. A support groove 4-8 is provided on the upper surface of the base frame 1, and a notch 4-9 is provided within the support groove 4-8, corresponding to the position of the mounting bracket 4-3.

[0035] In some examples, to achieve stable movement and rapid loading and unloading of the shuttle body 3, a drive connection assembly is designed. This assembly includes a moving block 4-1 controlled by a linear drive device consisting of a lead screw and a slide rail, which can reciprocate along a straight trajectory within the base frame 1. The positioning slot 4-2 at its top provides precise insertion positioning for the mounting frame 4-3. After the mounting frame 4-3 is inserted into the positioning slot 4-2, the anti-detachment block 4-4 at the top and the pressure plate 4-5 at the top of the moving block 4-1 form a limiting structure. The pressure plate 4-5 is rotatably mounted on the moving block 4-1 via a pin. The sleeve 4-6 on its surface corresponds to the anti-detachment block 4-4 and can be fitted together. Several springs 4-7 are connected between the pressure plate 4-5 and the moving block 4-1, and can generate a downward pulling force through elastic deformation, firmly pressing the mounting frame 4-3 onto the positioning slot 4-2 and the moving block 4-1, preventing the shuttle body 3 from shaking during movement.

[0036] The support groove 4-8 and notch 4-9 on the upper surface of the base frame 1 provide bottom support for the mounting frame 4-3 and support the pressure plate 4-5 during movement, preventing it from opening. The notch 4-9 provides space for the insertion and removal of the mounting frame 4-3. When it is necessary to replace the small shuttle body 3, simply press one end of the pressure plate 4-5 and lift the other end upwards to stretch the spring 4-7 and disengage the sleeve 4-6 from the anti-detachment block 4-4, allowing the mounting frame 4-3 to be pulled out quickly, thus achieving rapid replacement of the small shuttle body 3. When the linear drive device moves the moving block 4-1, the mounting frame 4-3 and the small shuttle body 3 move synchronously along the linear guide rail 2. Due to the elastic locking of the pressure plate 4-5 and the anti-detachment block 4-4, the small shuttle body 3 maintains a stable straight trajectory during movement, meeting the accuracy requirements of the loom's overlocking operation.

[0037] like Figures 1-3As shown in the figure, the docking assembly 5 in this embodiment includes a pair of ear plates 5-1, which are fixed to the upper and lower ends of the linear guide rail 2 respectively. Bolts 5-2 are inserted into the ear plates 5-1 and are connected to the base frame 1 by threaded screwing. A pair of sleeve blocks 5-3 are provided on the side surface of the base frame 1, and a pair of locking blocks 5-4 are provided on one side of the linear guide rail 2. The locking blocks 5-4 are all inserted into the sleeve blocks 5-3. The sleeve blocks 5-3 are U-shaped in general, and the locking blocks 5-4 are L-shaped in general.

[0038] In some examples, to achieve the effect of quick replacement of the linear guide rail 2 with the small shuttle body 3, a docking assembly 5 is designed. This assembly includes ear plates 5-1 fixed at both ends of the linear guide rail 2. Bolts 5-2 are inserted into the ear plates 5-1, and the bolts 5-2 are screwed into the inner side of the base frame 1 through threads to form a fixed connection. The U-shaped sleeve block 5-3 on the side surface of the base frame 1 and the L-shaped locking block 5-4 on the side of the linear guide rail 2 form a secondary positioning structure. The locking block 5-4 can be inserted from the U-shaped opening of the sleeve block 5-3. The lateral displacement of the linear guide rail 2 is restricted by the engagement of the right-angled side of the L-shape with the inner wall of the sleeve block 5-3.

[0039] When it is necessary to replace the shuttle with one of a different specification, simply loosen the bolt 5-2 on the ear plate 5-1, pull the L-shaped locking block 5-4 out of the U-shaped sleeve block 5-3, and the original linear guide rail 2 can be removed and replaced with a linear guide rail 2 that is compatible with the new shuttle specification. When installing the new guide rail, first insert the locking block 5-4 into the sleeve block 5-3, and then tighten it with the bolt 5-2 on the ear plate 5-1 to ensure a stable connection between the linear guide rail 2 and the base frame 1. The double connection between the bolt 5-2 and the locking block 5-4 and sleeve block 5-3 ensures the stability of the linear guide rail 2 installation and allows for quick guide rail replacement according to the size and movement trajectory requirements of the shuttle body 3, improving the adaptability and flexibility of the loom's selvedge transmission mechanism.

[0040] For example, such as Figure 1 As shown, the anti-detachment block 4-4 has a cylindrical structure, and the sleeve opening 4-6 has a semi-circular opening structure.

[0041] In some examples, the anti-detachment block 4-4 has a cylindrical structure, and the sleeve 4-6 has a semi-circular opening structure, forming a dual function of elastic locking and quick assembly / disassembly. The cylindrical anti-detachment block 4-4 is vertically fixed to the top of the mounting bracket 4-3, and its smooth cylindrical surface and the semi-circular sleeve 4-6 on the surface of the pressure plate 4-5 form a precise fit. When the pressure plate 4-5 is rotated and pressed down by the pin, the arc surface of the semi-circular sleeve 4-6 will tightly wrap around the cylindrical anti-detachment block 4-4. Using the elastic force of the spring 4-7 between the pressure plate 4-5 and the moving block 4-1, the mounting bracket 4-3 is firmly locked in the positioning slot 4-2. The symmetry of the cylindrical structure ensures uniform force distribution in all directions, preventing the mounting bracket 4-3 from tilting. The semi-circular opening design allows the sleeve 4-6 to quickly detach from the anti-detachment block 4-4 when the pressure plate 4-5 is lifted. The operator only needs to pull the pressure plate 4-5 upward to release the lock, enabling quick insertion and removal of the mounting bracket 4-3. This structure not only ensures the stability of the shuttle body 3 when it moves, but also simplifies the replacement process.

[0042] For example, such as Figure 3 As shown, the inner end face of the support groove 4-8 is slidably attached to the bottom surface of the pressure plate 4-5.

[0043] In some examples, the inner end face of the support groove 4-8 is in sliding contact with the bottom surface of the pressure plate 4-5, providing guidance and support for the rotation of the pressure plate 4-5. The support groove 4-8 is formed on the upper end face of the base frame 1, and its inner sidewall is in sliding contact with the plane of the bottom surface of the pressure plate 4-5. The inner end face of the support groove 4-8 can restrict the angular rotation of the pressure plate 4-5. The sliding contact surface is usually polished to reduce frictional resistance, making the rotation of the pressure plate 4-5 smoother, while reducing wear and extending the service life of the component.

[0044] For example, such as Figure 1 As shown, one end of the pressure plate 4-5 extends outward beyond the inner side of the base frame 1.

[0045] In some examples, one end of the pressure plate 4-5 extends outward beyond the inner side of the base frame 1, optimizing operational convenience. The extended portion extends beyond the inner edge of the base frame 1, forming an operating end that facilitates finger application. Operators can directly manipulate the extended end of the pressure plate 4-5 by hand, overcoming the resistance of the spring 4-7 to lift the pressure plate 4-5, allowing the sleeve 4-6 to disengage from the anti-detachment block 4-4. In scenarios requiring frequent replacement of the small shuttle body 3, this significantly reduces disassembly time and improves production efficiency. Simultaneously, the positional design of the extended end ensures that the operator's hand movements maintain a reasonable distance from the rotation axis of the pressure plate 4-5, avoiding interference during operation and making the entire replacement process safer and more convenient.

[0046] In actual use: Fix the base frame 1 to the main body of the loom. Install the linear guide rail 2 on the outside of the base frame 1 through the docking assembly 5. Fix the small shuttle body 3 to one end of the mounting frame 4-3. Insert the mounting frame 4-3 into the positioning slot 4-2 on the top of the moving block 4-1. Rotate the pressure plate 4-5 to make the sleeve 4-6 fit onto the anti-detachment block 4-4. The spring 4-7 stretches to generate elastic force, pressing the mounting frame 4-3 tightly into the positioning slot 4-2, thus completing the installation of the small shuttle body 3. Start the linear drive device to drive the moving block 4-1 to move along a straight track within the base frame 1. The moving block 4-1 drives the small shuttle body 3 to reciprocate in the linear guide rail 2 through the mounting frame 4-3 to perform the sewing operation. When it is necessary to replace the small shuttle body 3, press the outward-extending end of the pressure plate 4-5 to make the pressure plate 4-5 rotate around the pin. The sleeve 4-6 disengages from the anti-detachment block 4-4. Pull the mounting frame 4-3 upward to remove the small shuttle body 3. If the linear guide 2 needs to be replaced, loosen the bolt 5-2 on the ear plate 5-1, pull the L-shaped locking block 5-4 on the side of the linear guide 2 out of the U-shaped sleeve block 5-3 on the base frame 1, remove the original guide rail, insert the locking block 5-4 of the new guide rail into the sleeve block 5-3, and tighten the bolt 5-2 on the ear plate 5-1 to fix it.
