Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, specifically to a novel reed structure for a glass fiber cloth weaving machine. Background Technology

[0002] The reed is a crucial component in a fiberglass cloth weaving machine, primarily used to maintain yarn alignment and tension, ensuring the fabric's structure and quality. Reeds are typically made of high-strength steel, possessing excellent wear and corrosion resistance, and can withstand high production speeds and heavy loads.

[0003] Chinese Patent No. CN212335440U discloses a novel reed structure for a glass fiber cloth weaving machine. It includes two parallel reed beams and several reed teeth. The two ends of each reed tooth are slidably connected between the two reed beams. A through groove is provided on one side of each reed beam. This invention allows for convenient adjustment of the distance between the reed teeth.

[0004] Regarding the aforementioned technologies, this reed structure has some shortcomings. In actual use, to limit the movement of the reed teeth, operators must simultaneously adjust the upper and lower locking nuts on the reed beam to effectively fix the reed teeth. However, these two locking nuts are not equipped with a synchronization mechanism, thus requiring manual adjustment. This manual operation makes it difficult to guarantee precision and consistency, potentially leading to errors during adjustment. During manual adjustment, the tightness of the two locking nuts may differ, resulting in inconsistent fixing effects. This inconsistency may cause the reed teeth to be loosely fixed, affecting its stability and performance. Therefore, it is necessary to provide a novel reed structure for fiberglass cloth weaving machines to solve these technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel reed structure for a glass fiber cloth weaving machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The inserts pass through the through slot and extend into the interior of the reed beam. The inserts and reed teeth are alternately arranged. An adjustment mechanism is provided on the back of the support beam. A synchronization mechanism is provided on one side between two reed beams. A limit groove is provided on one side of the inner wall of the reed beam.

[0010] An adjusting screw is rotatably installed inside the limiting groove. A slider is sleeved on the outer wall of the adjusting screw and is slidably connected to the limiting groove. A pressure plate is fixedly installed on the back of the slider, and an abutment block is fixedly installed on the side of the pressure plate near the reed tooth plate.

[0011] Preferably, the adjustment mechanism includes a limiting box, which is fixedly installed on the back of the support beam. An operating box is fixedly installed on the back of the limiting box. A threaded rod is rotatably installed inside the limiting box on the back of the support beam. The rear end of the threaded rod passes through the limiting box and extends into the operating box, where it is rotatably connected to a bearing installed on the inner wall of the operating box. A second worm is rotatably installed inside the operating box. A second worm wheel is fixedly installed on the outer wall of the rear end of the threaded rod, and the second worm wheel meshes with the second worm. One end of the second worm passes through the operating box and extends to one side of the operating box. A second knob is fixedly installed on one end of the second worm. An adjustment plate is sleeved on the outer wall of the threaded rod and is slidably connected to the inner wall of the limiting box. A push rod is fixedly installed on the front of the adjustment plate. The push rod passes through a sliding hole opened on the back of the support beam and extends into the back of the support beam, where it is fixedly connected to the back of the movable guide rail.

[0012] Preferably, the synchronization mechanism includes a first worm gear, which is rotatably mounted on one side between two reed beams. A rotating shaft is rotatably mounted on one side inside each of the two reed beams. A second bevel gear is fixedly mounted on the outer wall of one end of the adjusting screw. A first bevel gear is fixedly mounted on the front end of the rotating shaft, and the first bevel gear meshes with the second bevel gear. A first worm wheel is fixedly mounted on the outer wall of the rotating shaft, and the first worm wheel meshes with the first worm gear. The top end of the first worm gear extends to one side above the top of the reed beam, and a first knob is fixedly mounted on the top end of the first worm gear.

[0013] Preferably, a marker rod is fixedly installed on the back of the movable guide rail on one side of the push rod, and the rear end of the marker rod passes through a sliding hole opened on the support beam and extends to the rear of the support beam.

[0014] Preferably, the front side of the adjusting plate is provided with a threaded hole that matches the threaded rod, and the adjusting plate is threadedly connected to the threaded rod through the threaded hole on its front side.

[0015] Preferably, the slider has a threaded hole on one side that matches the adjusting screw, and the slider is threadedly connected to the adjusting screw through the threaded hole on one side.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes the coordinated use of a reed beam, support beam, reed teeth, connecting plate, synchronization mechanism, pressure plate, first knob, adjustment mechanism, insert block, movable guide rail, contact block, through groove, rotating shaft, adjusting screw, limit groove, and slider. Through the synchronization mechanism, the synchronous and consistent movement of the two contact blocks is ensured, eliminating inconsistencies caused by manual operation and ensuring that the two contact blocks always maintain the same positional relationship. Simultaneously, it ensures that the fixing force applied to the reed teeth by the two contact blocks during operation is similar, thereby improving the stability of the fixing effect and ensuring stable operation and long-term reliability of the equipment.

[0018] 2. This invention utilizes the self-locking characteristic of the worm gear to ensure that the insert block, after adjustment, can be securely embedded between adjacent reed teeth, thereby effectively maintaining its positional stability. After adjustment, the worm gear mechanism will not loosen due to external forces, ensuring that the insert block remains in the correct position. Furthermore, the abutment block stably abuts against the side of the rightmost reed tooth, providing effective restraint for the reed tooth. This design greatly improves the stability and reliability of the reed structure during use, reduces the risk of wear or failure due to improper positioning, and ensures the normal operation of the equipment.

[0019] 3. This utility model, through the setting of the marking rod, requires the position of the insert blocks to be controlled by the movable guide rail when adjusting the spacing between the reed teeth. The back-and-forth movement of the movable guide rail drives the marking rod to move as well. The scale on the marking rod provides a visual reference, allowing workers to ensure that the positions of the upper and lower sets of insert blocks are consistent when adjusting them. In this way, by referring to the scale on the marking rod, precise synchronous adjustment of the two sets of insert blocks can be achieved, ensuring final positional consistency and improving the accuracy and efficiency of the adjustment.

[0036] In one preferred embodiment, a marker rod 26 is fixedly mounted on the back of the movable guide rail 13, located on one side of the push rod 27. The rear end of the marker rod 26 passes through a sliding hole in the support beam 2 and extends to the rear of the support beam 2.

[0038] In one preferred embodiment, a threaded hole adapted to the adjusting screw 20 is provided on one side of the slider 22, and the slider 22 is threadedly connected to the adjusting screw 20 through the threaded hole on one side.

[0039] The working principle of this utility model is as follows: All parts not described in this device are the same as or can be implemented using existing technology. When it is necessary to adjust the spacing between the reed teeth 3, firstly, rotate the first knob 8. The rotation of the first knob 8 drives the first worm 6 to rotate. Through the meshing of the first worm 6 and the first worm wheel 17, the two rotating shafts 16 rotate synchronously. The rotation of the rotating shafts 16 drives the first bevel gear 18 to rotate. Through the meshing of the first bevel gear 18 and the second bevel gear 19, the second bevel gear 19 drives the adjusting screw 20 to rotate. Therefore, through the transmission of the synchronization mechanism 5… The two adjusting screws 20 can rotate synchronously. By adjusting the threaded transmission between the adjusting screws 20 and the slider 22, and the sliding relationship between the slider 22 and the limiting groove 21, the slider 22 can move laterally stably. The movement of the slider 22 drives the pressure plate 7 to move, and the movement of the pressure plate 7 drives the abutment block 14 to move. Therefore, by rotating the first knob 8, the positions of the two abutment blocks 14 can be controlled synchronously, moving the abutment block 14 to the rightmost position inside the reed beam 1. Subsequently, rotating the second knob 9 drives the second worm gear 25 to rotate. Through the meshing of the second worm gear 25 and the second worm wheel 24, the second worm wheel 25 rotates. 4. The threaded rod 23 is rotated. Through the threaded transmission between the threaded rod 23 and the adjusting plate 28, and the sliding relationship between the adjusting plate 28 and the limit box 11, the adjusting plate 28 moves stably back and forth. The movement of the adjusting plate 28 causes the push rod 27 to make sliding contact with the support beam 2. During the movement of the push rod 27 inside the support beam 2, it pushes the movable guide rail 13 to move. The movement of the movable guide rail 13 causes the insert block 12 to move, so that the insert block 12 is inserted deeper and deeper between two adjacent reed teeth 3, thereby changing the spacing between the reed teeth 3. After the spacing of the reed teeth 3 is adjusted, it is then... Rotating the first knob 8 controls the two contact blocks 14 to move synchronously, causing the contact blocks 14 to move towards the reed tooth 3 and abut against the side of the rightmost reed tooth 3, effectively fixing the position of the reed tooth 3. Through the setting of the synchronization mechanism 5, the synchronous and consistent movement of the two contact blocks 14 is ensured, eliminating the inconsistency caused by manual operation and ensuring that the two contact blocks 14 always maintain the same positional relationship. At the same time, it ensures that the fixing force applied by the two contact blocks 14 to the reed tooth 3 during operation is similar, thereby improving the stability of the fixing effect and ensuring the stable operation and long-term reliability of the equipment.
