Description

Technical Field

[0001] This utility model belongs to the field of rapier loom transmission wheel installation, and specifically relates to an auxiliary device for rapier loom transmission wheel installation. Background Technology

[0002] Rapier looms are widely used in the textile industry, and the stable operation of their rapier wheels is crucial to the loom's operation. The rapier wheels need to be installed precisely to ensure the efficient operation of the weft insertion system and to guarantee the quality of the fabric and production efficiency. With the development of textile technology, the requirements for the precision and convenience of installing rapier loom rapier wheels are constantly increasing. Against this background, an auxiliary device for installing rapier loom rapier wheels has emerged, aiming to make the installation process of rapier wheels smoother and more efficient.

[0003] Under the current technology, the installation method of the rapier loom's transmission rapier wheel has many advantages. The traditional installation method has been practiced for a long time and is technically mature. The relevant operators have a low learning curve and can quickly carry out the installation work. The installation tools are common and inexpensive, which effectively controls the company's equipment maintenance investment. In addition, the existing installation process is relatively clear and can ensure the basic concentricity and perpendicularity of the transmission rapier wheel after installation, so that the loom can operate normally, maintain a certain production efficiency, and lay the foundation for textile production.

[0004] Although the existing technology makes the installation relatively easy for operators to learn and allows for quick commencement of the work, and the installation tools are common and inexpensive, effectively controlling the company's equipment maintenance investment, and the existing installation process is relatively clear, ensuring basic concentricity and perpendicularity of the transmission wheel after installation, the current technology lacks a better and faster process for installing the transmission wheel of the rapier loom. It relies on manual alignment, which is time-consuming. There is no dedicated auxiliary positioning structure during installation, which easily leads to deviations and requires repeated adjustments. Workers need to spend more energy on alignment, which is not conducive to increasing the installation workload and is difficult to adapt to the needs of high-efficiency production. The overall installation efficiency needs to be further improved. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary device for installing the rapier loom's transmission wheel, so as to solve the problem of installing the transmission wheel of the rapier loom.

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

[0007] An auxiliary device for installing a rapier loom's transmission wheel includes a rapier body. A fixing plate is integrally formed around the inside of the rapier body. A circular plate is integrally formed at the end of the fixing plate away from the rapier body. An internal threaded groove is provided at the center of the circular plate. A mounting seat is provided on one side inside the rapier body. A connecting seat is fixedly installed at the end of the mounting seat away from the rapier body. A fixing seat is fixedly installed at the end of the connecting seat away from the mounting seat. Rotating handles are integrally formed on both sides of the outer ring of the fixing seat. A connecting column is fixedly installed at the end of the fixing seat away from the connecting seat. Multiple limiting rods are slidably installed inside the connecting seat and the mounting seat. A baffle is fixedly installed at the end of each limiting rod away from the connecting seat. A handle is fixedly installed at the end of the baffle away from the limiting rod. The end of the handle near the limiting rod slides inside the connecting column. Fixing components are provided around the inside of the mounting seat. The fixing components are threadedly connected to two of the fixing plates. The limiting rods slide inside the circular plate. A mating seat is threadedly connected to the end of the internal threaded groove away from the mounting seat.

[0008] As a preferred technical solution, the fixing component includes a circular groove, a knob, a rotating column, a movable column, a threaded rod, a movable hole, and an internally threaded hole. The two fixing plates have internally threaded holes inside. The mounting base has movable holes at both the top and bottom ends on the side closest to the sword wheel body. A movable column is rotatably installed inside the movable hole. A threaded rod is fixedly installed at the end of the movable column closest to the sword wheel body, and the threaded rod is threaded into the internally threaded hole. The mounting base has circular grooves at both the top and bottom ends on the side furthest from the sword wheel body. A rotating column is fixedly installed at the end of the movable column furthest from the threaded rod, and the rotating column is rotatably installed inside the circular groove. A knob is fixedly installed at the end of the rotating column furthest from the movable column.

[0009] As a preferred technical solution, both the mounting base and the connecting base are provided with multiple limiting holes, and the limiting rod slides inside the limiting holes.

[0010] As a preferred technical solution, the circular plate has multiple limiting grooves on the outer ring of the internal thread groove, and the limiting rod is inserted into the limiting groove through the limiting hole.

[0011] As a preferred technical solution, a tension hole is provided inside the end of the connecting column away from the fixed seat, and a telescopic rod is fixedly installed at the center of the tension hole. The end of the telescopic rod away from the tension hole is fixedly installed at the end of the connecting column near the baffle.

[0012] As a preferred technical solution, a spring is fixedly installed inside the tension hole on the outer ring of the telescopic rod, and the end of the spring away from the tension hole is fixedly installed on one side of the baffle. The spring is located on the outer ring of the telescopic rod.

[0013] As a preferred technical solution, the baffle and the handle are provided with guide grooves around their interior, and a guide rod is fixedly installed around one end of the connecting column near the baffle. The guide rod is slidably installed inside the guide groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, by symmetrically adjusting the upper and lower knobs, the mounting base and the fixing plate can be rigidly locked to ensure that the relative position of the device as a whole and the sword wheel body is fixed, thus avoiding reference deviation during installation. The clamping and pre-positioning of the sword wheel is achieved through the limiting rod assembly. The operator holds the handle and pulls the baffle outward. The baffle drives the limiting rod to slide along the limiting holes of the mounting base and the connecting base. At this time, the telescopic rod in the connecting column extends with the stretching of the baffle, and the outer spring is compressed and stores energy. After aligning the sword wheel with the device, the handle is released, and the spring releases its elastic potential energy to push the baffle to reset. The limiting rod passes through the limiting hole and inserts into the limiting groove of the circular plate. Through the circumferential distribution of multiple sets of limiting rods, the sword wheel is circumferentially positioned on the device to prevent it from rotating or shifting during installation.

[0016] Secondly, the threaded connection of the fixed components ensures the perpendicularity of the transmission wheel to the frame, and the circumferential constraint of the limiting rod prevents the transmission wheel from tilting, thus achieving one-time precise installation of the transmission wheel. After installation, turn the knob in the opposite direction to disengage the threaded rod from the internal threaded hole, and pull the handle to remove the limiting rod from the limiting groove. The device can then be removed from the transmission wheel, completing the entire installation process. Attached Figure Description

[0022] Example

[0023] refer to Figs. 1-4 This embodiment of an auxiliary device for installing a rapier loom's transmission rapier wheel includes a rapier wheel body 1. A fixing plate 21 is integrally formed around the inside of the rapier wheel body 1. A circular plate 24 is integrally formed at the end of the fixing plate 21 away from the rapier wheel body 1. An internal thread groove 23 is provided at the center of the circular plate 24. A mounting seat 10 is provided on one side inside the rapier wheel body 1. A connecting seat 9 is fixedly installed at the end of the mounting seat 10 away from the rapier wheel body 1. A fixing seat 3 is fixedly installed at the end of the connecting seat 9 away from the mounting seat 10. Rotating handles 8 are integrally formed on both sides of the outer ring of the fixing seat 3. The fixing seat 3 is located away from the connecting seat 10. A connecting post 7 is fixedly installed at one end of the connector 9. Multiple limiting rods 4 are slidably installed inside the connector 9 and the mounting base 10. A baffle 6 is fixedly installed at the end of the limiting rod 4 away from the connector 9. A handle 5 is fixedly installed at the end of the baffle 6 away from the limiting rod 4. The handle 5 slides inside the connecting post 7 at the end close to the limiting rod 4. Fixing components 20 are provided around the inside of the mounting base 10. The fixing components 20 are threadedly connected inside two fixing plates 21. The limiting rod 4 slides inside the circular plate 24. A mating seat 11 is threadedly connected at the end of the internal thread groove 23 away from the mounting base 10.

[0024] refer to Figs. 2-3 The fixing assembly 20 includes a circular groove 25, a knob 2, a rotating column 15, a movable column 14, a threaded rod 13, a movable hole 12, and an internally threaded hole 26. The two fixing plates 21 have internally threaded holes 26 inside. The mounting base 10 has movable holes 12 at both ends on the side closest to the sword wheel body 1. The movable column 14 is rotatably mounted inside the movable hole 12. A threaded rod 13 is fixedly mounted at the end of the movable column 14 closest to the sword wheel body 1. The threaded rod 13 is threaded into the internally threaded hole 26. The mounting base 10 has a circular groove 25 at both ends on the side furthest from the sword wheel body 1. A rotating column 15 is fixedly installed at the end of the movable column 14 away from the threaded rod 13. The rotating column 15 is rotatably installed inside the circular groove 25. A knob 2 is fixedly installed at the end of the rotating column 15 away from the movable column 14. The threaded connection of the fixing component 20 ensures the perpendicularity of the transmission wheel to the frame. The circumferential constraint of the limiting rod 4 prevents the transmission wheel from tilting. Finally, the transmission wheel is installed accurately in one go. After installation, the knob 2 is rotated in the opposite direction to disengage the threaded rod 13 from the internal threaded hole 26. The handle 5 is pulled to disengage the limiting rod 4 from the limiting groove 22. The device can then be disassembled from the transmission wheel, completing the entire installation process.

[0025] refer to Figs. 2-4Both the mounting base 10 and the connecting base 9 have multiple limiting holes 28 inside. The limiting rod 4 slides inside the limiting holes 28. The circular plate 24 has multiple limiting grooves 22 on the outer ring of the internal thread groove 23. The limiting rod 4 is inserted into the limiting groove 22 through the limiting holes 28. The limiting rod 4 passes through the limiting holes 28 and is inserted into the limiting groove 22 of the circular plate 24. Through the circumferential distribution of multiple sets of limiting rods 4, the transmission wheel is circumferentially positioned on the device to prevent it from rotating or shifting during installation. During this process, the guide rods 16 around the connecting column 7 slide along the guide grooves 17 of the baffle 6 and the handle 5 to ensure the linearity of the extension and retraction of the limiting rod 4 and avoid jamming caused by uneven force. Precise alignment and installation are the core execution links. A tension hole 27 is provided inside the end of the connecting column 7 away from the fixed seat 3. A telescopic rod 19 is fixedly installed at the center of the tension hole 27. The end of the telescopic rod 19 away from the tension hole 27 is fixedly installed at the end of the connecting column 7 near the baffle 6. A spring 18 is fixedly installed inside the tension hole 27 on the outer ring of the telescopic rod 19. The end of the spring 18 away from the tension hole 27 is fixedly installed on one side of the baffle 6. The spring 18 is located on the outer ring of the telescopic rod 19. The baffle 6 drives the limiting rod 4 to slide along the limiting hole 28 of the mounting seat 10 and the connecting seat 9. At this time, the telescopic rod 19 in the connecting column 7 is stretched as the baffle 6 is stretched, and the outer ring spring 18 is compressed and stores energy. After the transmission wheel is aligned with the device, the handle 5 is released, and the spring 18 releases its elastic potential energy to push the baffle 6 to reset.

[0026] refer to Figs. 1-2 The baffle 6 and the handle 5 have guide grooves 17 around their interior. The connecting post 7 is fixedly installed with guide rods 16 around one end of the baffle 6. The guide rods 16 are slidably installed inside the guide grooves 17. During this process, the guide rods 16 around the connecting post 7 slide along the guide grooves 17 of the baffle 6 and the handle 5 to ensure the linearity of the extension and retraction of the limiting rod 4 and avoid jamming caused by uneven force.

[0027] Operating principle and advantages: During the installation preparation stage, the initial docking of the device with the loom must be completed first. The operator moves the device by rotating the handles 8 on both sides of the fixed seat 3, aligning one side of the mounting seat 10 with the fixed plate 21 inside the sword wheel body 1. At this time, the side of the mounting seat 10 closest to the sword wheel body 1 has a pre-set installation position that matches the fixed plate 21. By observing the relative position of the internal thread groove 23 of the circular plate 24 and the loom drive shaft, the overall posture of the device is initially adjusted, laying the foundation for subsequent precise positioning. The positioning benchmark establishment relies on the synergistic effect of multiple structures. The core benchmark of the device comes from the coaxiality design of the internal thread groove 23 of the circular plate 24 and the loom drive shaft. The internal thread groove 23 can be threadedly connected to the docking seat 11, and the docking seat 11 is pre-calibrated with the loom drive shaft. The mounting base 10 is fixed, forming a rigid reference chain of transmission shaft, docking seat 11, and circular plate 24. Simultaneously, the mounting base 10 further enhances reference stability through the connection between the fixing component 20 and the fixing plate 21. The operator rotates the knobs 2 on both sides of the mounting base 10, causing the rotating column 15 to rotate within the circular groove 25. The rotating column 15 drives the movable column 14 to rotate within the movable hole 12, thereby causing the threaded rod 13 at the front end of the movable column 14 to screw into the internal threaded hole 26 of the fixing plate 21. By symmetrically adjusting the two knobs 2, the mounting base 10 and the fixing plate 21 can be rigidly locked, ensuring the relative position of the entire device and the sword wheel body 1 is fixed, preventing reference offset during installation. The clamping and pre-positioning of the transmission sword wheel are achieved through the limiting rod 4 component. The operator holds the handle 5. Pulling the baffle 6 outward causes the limiting rod 4 to slide along the limiting holes 28 of the mounting base 10 and the connecting base 9. At this time, the telescopic rod 19 inside the connecting column 7 extends as the baffle 6 is stretched, and the outer spring 18 is compressed and stores energy. After aligning the transmission wheel with the device, the handle 5 is released, and the spring 18 releases its elastic potential energy to push the baffle 6 back to its original position. The limiting rod 4 passes through the limiting hole 28 and inserts into the limiting groove 22 of the circular plate 24. Through the circumferential distribution of multiple sets of limiting rods 4, the transmission wheel is circumferentially positioned on the device to prevent it from rotating or shifting during installation. During this process, the guide rods 16 around the connecting column 7 slide along the guide grooves 17 of the baffle 6 and the handle 5 to ensure the linearity of the telescopic movement of the limiting rod 4 and avoid jamming caused by uneven force. Precise alignment and installation are crucial. In the execution phase, after clamping the transfer wheel, the operator fine-tunes the overall position of the device by rotating handle 8. Utilizing the threaded engagement between the internal thread groove 23 of the circular plate 24 and the threaded connection of the docking seat 11, the transfer wheel is slowly screwed into the preset position on the loom's drive shaft. Since the limiting rod 4 maintains the relative fixation between the transfer wheel and the circular plate 24, and the circular plate 24 is coaxial with the drive shaft via the docking seat 11, the transfer wheel's shaft hole can be precisely aligned with the drive shaft's center. During installation, the threaded connection of the fixing component 20 ensures the perpendicularity of the transfer wheel to the frame, and the circumferential constraint of the limiting rod 4 prevents the transfer wheel from tilting, ultimately achieving a precise one-time installation of the transfer wheel. After installation, the knob 2 is rotated in the opposite direction to disengage the threaded rod 13 from the internal threaded hole 26, and the handle 5 is pulled to disengage the limiting rod 4 from the limiting groove 22.The device can then be detached from the sword-transfer wheel, completing the entire installation process.
