Description

Technical Field

[0001] This utility model belongs to the field of rapier loom guide rail technology, and specifically relates to a rigid rapier loom air cushion guide rail. Background Technology

[0002] Currently, moving guide rails are the most commonly used reciprocating moving mechanisms in processing equipment. They typically consist of a fixed part and a moving part. The fixed part is installed on the equipment, while the moving part is set on the object to be moved. The relative movement between the fixed part and the moving part is used to achieve the relative movement of the moving part. They play an important guiding and supporting role in the operation of various equipment. In the existing technology, the fixed part and the moving part of the moving guide rail are mostly of the direct contact structure. This structure inevitably generates friction during relative movement. After long-term use, the contact surface is prone to wear, which can even lead to component damage in severe cases, affecting the normal use of the equipment. At the same time, the replacement and maintenance of worn components not only increases downtime but also makes maintenance costs high, causing many inconveniences to production.

[0003] To improve this situation, Chinese Patent No. CN203741511U discloses an air cushion guide rail for a rigid rapier loom. This guide rail has an air cushion block below the rapier, and the air cushion block has a compressed air inlet connected to a compressed air source. The compressed air inlet opens onto the surface of the air cushion block located below the rapier through an internal air chamber. Through the action of the air cushion, the direct contact between the rapier and the guide rail is reduced, effectively solving problems such as poor component rigidity, unstable operation, and high maintenance costs in existing technologies. It has advantages such as stable operation, low power consumption, and low maintenance costs.

[0004] However, the aforementioned air cushion guide rail structure still has certain defects and shortcomings in practical applications. The guide rail as a whole lacks an effective connection structure. When applied to rapier looms, the guide rail length required by different specifications of rapier looms varies, and the guide rail cannot be flexibly connected and installed according to specific installation and usage requirements. It is difficult to adapt to looms with different length requirements. This limitation greatly restricts its applicability when facing diverse production needs. Therefore, it is necessary to further improve its design. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a rigid rapier loom air cushion guide rail to solve the problems raised in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A rigid rapier loom air cushion guide rail includes several guide rail bodies. An air supply pipe is fixedly installed at the bottom of each guide rail body. Exhaust holes are equally spaced inside the bottom of each guide rail body. The output end of the air supply pipe is connected to the exhaust holes. Splicing mechanisms are fixedly installed at both ends of each guide rail body. Each guide rail body is spliced ​​together with the others through the splicing mechanisms.

[0008] The splicing mechanism includes a docking rail and a docking block. The docking rail is fixedly installed on both ends of the back side and both ends of the front side of the guide rail body.

A limit card group is fixedly installed on the top of the docking block, and the limit card group engages with the docking block inside the docking rail.

[0009] As a preferred technical solution, one end of the gas supply pipe is provided with a connection slot, and the other end of the gas supply pipe is fixedly installed with an insertion tube, which is inserted into the connection slot of another gas supply pipe.

[0010] As a preferred technical solution, a sealing sleeve is fixedly installed on the outer surface of the cannula, and the outer side of the sealing sleeve is in close contact with the inner wall of the connecting slot.

[0011] As a preferred technical solution, the tube is provided with an external air pipe connection internal thread, and the internal cavity of the guide rail body is convex in shape.

[0012] As a preferred technical solution, the top view of the docking rail is convex, the top view of the docking block is I-shaped, and the convex ends of the docking block are inserted into the interior of the docking rail.

[0013] As a preferred technical solution, the limiting clamping group includes a top rail and a locking hole. The locking hole is opened at the middle of the outer side of the docking block and the middle of the outer side of the docking rail. The top rail is fixedly installed on the top of the docking block. Limiting springs are fixedly installed at equal intervals inside the top rail. A movable block is fixedly installed at the outer end of the limiting spring. A limiting plate is fixedly installed at the bottom of the movable block.

[0024] Example

[0025] refer to Figures 1 to 5This embodiment of a rigid rapier loom air cushion guide rail includes several guide rail bodies 1. An air supply pipe 2 is fixedly installed at the bottom of the guide rail body 1. Exhaust holes 3 are opened at equal intervals inside the bottom of the guide rail body 1. The output end of the air supply pipe 2 is connected to the exhaust holes 3. Splicing mechanisms 6 are fixedly installed at both ends of the guide rail body 1. Each guide rail body 1 is spliced ​​together with the others through the splicing mechanisms 6.

[0026] The splicing mechanism 6 includes a docking rail 61 and a docking block 62. The docking rail 61 is fixedly installed on both ends of the back side and both ends of the front side of the guide rail body 1. Both ends of the docking block 62 are inserted into the interior of the docking rail 61. A limit locking group 63 is fixedly installed on the top of the docking block 62. The limit locking group 63 engages with the docking block 62 inside the docking rail 61. During the application of this device, the guide rail body 1 can be combined with multiple bodies through the splicing mechanism 6 to adapt to different installation requirements. When splicing is required, both ends of the docking block 62 are inserted into the interior of the docking rail 61 of the adjacent guide rail body 1, so that the guide rail bodies 1 are initially connected into a whole. The limiting latch 63 at the top of the docking block 62 engages with the docking block 62 inside the docking rail 61, thereby fixing the assembled guide rail body 1 and preventing loosening or displacement during use. At the same time, the air supply pipe 2 supplies gas to the guide rail body 1, and the gas is discharged through the vent holes 3 at equal intervals at the bottom of the guide rail body 1, forming an air cushion on the surface of the guide rail body 1. This reduces the direct contact between the scissor and the guide rail. This splicing method allows the guide rail to be flexibly adjusted in length according to actual needs, improving the applicability of the device. The formation of the air cushion reduces friction between components, helps extend the service life of the equipment, and ensures the stability of operation.

[0027] refer to Figures 1-5The limiting block 63 includes a top rail 631 and a locking hole 632. The locking hole 632 is located at the middle of the outer side of the mating block 62 and the middle of the outer side of the mating rail 61. The top rail 631 is fixedly installed on the top of the mating block 62. Limiting springs 633 are fixedly installed at equal intervals inside the top rail 631. A movable block 634 is fixedly installed on the outer end of the limiting spring 633. A limiting plate 635 is fixedly installed on the bottom of the movable block 634. Locking pins 636 are fixedly installed on both sides of the lower end of the limiting plate 635. The ends of the locking pins 636 pass through... The locking hole 632 on the connecting rail 61 is inserted into the inner side of the locking hole 632 in the middle of the outer side of the connecting block 62. An adjusting handle 637 is fixedly connected to the outer side of the limiting plate 635. The adjusting handle 637 is U-shaped. During the application of this device, its limiting locking group 63 plays the role of fixing the connecting block 62 and the connecting rail 61 during the splicing of the guide rail body 1. When the guide rail needs to be spliced, the U-shaped adjusting handle 637 is operated to drive the limiting plate 635 to move. The movement of the limiting plate 635 causes the movable block 634 to compress the top rail 6. The limiting spring 633 inside 31, at this time, the locking pins 636 on both sides of the lower end of the limiting plate 635 retract from the locking holes 632 in the middle of the outer side of the docking block 62. After adjusting the docking block 62 and the docking rail 61 to the appropriate position, release the adjusting handle 637. The limiting spring 633 resets and pushes the movable block 634. The movable block 634 drives the limiting plate 635 to move back, so that the end of the locking pin 636 passes through the locking hole 632 on the docking rail 61 and re-inserts into the locking hole 632 in the middle of the outer side of the docking block 62, completing the docking and fixing. Top rail 631 provides the mounting base for the limit spring 633 and the movable block 634. The elastic force of the limit spring 633 ensures that the locking pin 636 can be stably engaged in the locking hole 632. The position setting of the locking hole 632 ensures the accuracy of the engagement of the locking pin 636. This structure makes the fixing operation of the guide rail splicing convenient and efficient. The cooperation between the locking pin 636 and the locking hole 632 enhances the firmness of the connection and avoids loosening after splicing. The design of the adjustable handle 637 facilitates the operation, improves the splicing efficiency, and ensures the stability of the overall structure of the guide rail.

[0028] refer to Figures 2-4The insertion tube 8 has an internally threaded external air pipe connection 5. The internal cavity of the guide rail body 1 has a convex cross-section. The top view of the docking rail 61 is also convex, and the top view of the docking block 62 is I-shaped. Both convex ends of the docking block 62 are inserted into the docking rail 61. During the application of this device, the internally threaded external air pipe connection 5 inside the insertion tube 8 can achieve a stable connection between the external air pipe and the insertion tube 8, ensuring a stable input of compressed air into the air supply pipe 2. The convex cross-section of the internal cavity of the guide rail body 1 is adapted to the structure of the rapier, providing suitable space for the reciprocating movement of the rapier and ensuring that the rapier moves smoothly during its movement. There will be no deviation or jamming during the process. The docking rail 61 is convex in shape when viewed from above, and the docking block 62 is I-shaped when viewed from above. When the convex parts at both ends of the docking block 62 are inserted into the docking rail 61, the convex and I-shaped structures fit together, increasing the tightness and stability of the docking. This makes it less likely for the main body 1 of the guide rail to shift under force. This structural design makes the connection of the external air pipe more reliable and avoids the problem of falling off during gas transportation. The convex cavity improves the smoothness of the rapier movement. The cooperation between the I-shaped docking block 62 and the convex docking rail 61 enhances the overall rigidity of the guide rail after it is spliced, reduces shaking during operation, and further ensures the stable operation of the device.

[0029] refer to Figures 1-4 One end of the gas supply pipe 2 has a connecting slot 7, and the other end of the gas supply pipe 2 is fixedly installed with a tube 8. The tube 8 is inserted into the connecting slot 7 of another gas supply pipe 2. A sealing sleeve 4 is fixedly installed on the outer surface of the tube 8. The outer side of the sealing sleeve 4 and the inner wall of the connecting slot 7 are fitted together to seal. During the application of this device, the gas supply pipe 2 can maintain the continuity of the gas passage when multiple guide rail bodies 1 are spliced. When connecting the gas supply pipes 2, the tube 8 of one gas supply pipe 2 is inserted into the connecting slot 7 of another gas supply pipe 2, so that the two gas supply pipes 2 form a passage. The sealing sleeve 8 on the outer surface of the tube 8 is sealed. The sleeve 4 then enters the connecting slot 7, and its outer side fits tightly against the inner wall of the connecting slot 7 to achieve a seal at the connection. In this way, compressed air can be stably delivered to each guide rail body 1 through the connected air supply pipe 2, ensuring that the exhaust port 3 continuously discharges gas to form an air cushion. The setting of the sealing sleeve 4 effectively prevents gas leakage at the connection, ensures the stability of the air supply pressure, maintains the air cushion effect, and reduces the friction between the sword rod and the guide rail. At the same time, this connection method, together with the splicing of the guide rail body 1, allows the overall air supply system to be flexibly adjusted according to the length of the guide rail, improving the adaptability of the device.

[0030] Operating principle and advantages: When using this device, first select several guide rail bodies 1 according to the required guide rail length of the rapier loom, and connect them through the splicing mechanism 6. Insert the convex ends of the connecting block 62 into the connecting rail 61 of the adjacent guide rail body 1 to make them initially fit together. During this period, operate the adjusting handle 637 to drive the limiting plate 635 to move. The limiting plate 635 stretches the limiting spring 633, allowing the locking pin 636 to exit from the locking hole 632 of the connecting block 62. After the position is aligned, release the adjusting handle 637. The limiting spring 633 returns to its original position and pushes the movable block 634. The movable block 634 drives the limiting plate 635 and the locking pin 636 to move, so that the end of the locking pin 636 passes through the locking hole 632 on the connecting rail 61 and is inserted into the locking hole 632 in the middle of the outer side of the connecting block 62. The splicing and fixing of the guide rail body 1 is completed. At the same time, when the guide rail bodies 1 are close to each other and fit together, the insertion tube 8 of one air supply pipe 2 is inserted into the connection slot 7 of the other air supply pipe 2. The sealing sleeve 4 on the outer surface of the insertion tube 8 fits against the inner wall of the connection slot 7 to achieve a sealed connection of the air supply pipe 2. This splicing process ensures the splicing accuracy through the cooperation of the docking block 62 and the docking rail 61. The locking pin 636 of the limit card group 63 and the locking hole 632 fix the splicing position, so that the guide rail can be flexibly combined according to the length requirements of different specifications of looms, solving the problem that the existing technology cannot flexibly dock and install, and improving the applicability of the guide rail. The fixing structure of the splicing mechanism 6 ensures the overall stability of the guide rail after splicing, reduces shaking during operation, and further ensures the reliability of equipment operation.

[0031] After installation and docking, the external air pipe can be connected to the insertion tube 8 of the air supply pipe 2. The external air pipe is connected to the internal thread 5 to achieve a stable connection with the output end of the external air supply equipment. Compressed air is input through the air supply pipe 2 and discharged from the exhaust hole 3 at the bottom of the guide rail body 1 through the connection between the output end of the air supply pipe 2 and the exhaust hole 3. An air cushion is formed on the surface of the guide rail body 1, reducing the direct contact between the scissor and the guide rail. This process continues the advantages of the existing air cushion guide rail, reducing friction and wear, maintaining stable operation, low power consumption, and low maintenance costs. At the same time, the sealing sleeve 4 enhances the sealing of the air supply pipe 2 docking point, preventing gas leakage from affecting the air cushion effect. Each component has a clear division of labor, and the splicing operation is convenient. The splicing and disassembly can be quickly completed by adjusting the handle 637, which facilitates later maintenance and length adjustment, adapts to diversified production needs, and improves the overall practicality and economy of the guide rail.

[0032] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
