TECHNICAL FIELD

[0001] The utility model relates to water-jet loom technical field, especially in a saddle -shaped loom cover with the clamping type guide plate. BACKGROUND

[0002] In the structure of the water-jet loom, the guide plate is a key component for guiding yarn and ensuring the smooth progress of the weaving process, and its installation and fixing method are crucial. Traditionally, the guide plate is usually fixed on the cover of the water-jet loom by screws, such as the spinning machine cover with multi-station guide plate disclosed in Chinese patent CN 218842486 U. However, due to the generation of a large amount of water mist during the operation of the water-jet loom, these water mists are easily attached to the cover and its components, including the screw connection of the guide plate. Long-term water mist erosion and humid environment make the screw connection prone to rust. Rusty screws not only are difficult to disassemble and replace, but also can cause the stability of the guide plate to decrease, and even cause the guide plate to loosen or fall off during the weaving process.

[0003] The loosening or falling off of the guide plate can seriously affect the normal progress of textile production, which may lead to yarn breakage, fabric defects and other problems, thereby reducing product quality and production efficiency. At the same time, rust at the screw connection also increases maintenance cost and difficulty, which requires operators to regularly check and replace, increasing the workload. SUMMARY

DETAILED DESCRIPTION

[0025] The utility model will be further described below in combination with the drawings.

[0026] The directions involved in the specification are based on the normal working direction of the saddle-shaped loom cover with the clamping type yarn guide plate, and are not limited to the storage and transportation directions, and only represent relative positional relationships, not absolute positional relationships.

[0027] Embodiment one:

[0028] As shown in Figure 1 , Figure 2 and Figure 3 , a saddle-shaped loom cover with a clamping type yarn guide plate is used to connect the left rear cover 2 and the left front cover 3. It comprises a cover body 1 and a yarn guide plate 4 installed on the cover body 1. A plurality of yarn guide holes 40 are formed in the yarn guide plate 4, and the axes of the yarn guide holes 40 are in the left-right direction. The yarn guide holes 40 are arranged side by side, which can optimize the path of the yarn and reduce the friction and wear between the yarn and the yarn guide plate, while ensuring that the yarn can be stably and accurately guided to the weaving area.

[0029] The cover body 1 and the yarn guide plate 4 are integrally formed of plastic, which has excellent corrosion resistance and stability.

[0030] Figures 1-5 As shown in the drawings, a clamping groove 12 with a top opening is provided on the cover body 1, and the bottom of the yarn guide plate 4 is inserted into the clamping groove 12. An elastic clamping structure is provided between the clamping groove 12 and the yarn guide plate 4, which is made of plastic and integrally formed with the yarn guide plate 4 or the clamping groove 12, to ensure the firm connection between the yarn guide plate 4 and the cover body 1, while avoiding the use of rust-prone connecting parts such as screws. The elastic clamping structure can adopt a cantilever hook structure or an elastic clamping jaw structure, as long as it can limit the insertion of the yarn guide plate 4 into the clamping groove 12.

[0031] As a preferred solution, the top of the cover body 1 is provided with a recess 11 recessed inwardly, and the yarn guide plate 4 is installed in the recess 11 to further stabilize the position of the yarn guide plate 4. The bottom of the recess 11 is provided with a clamping groove 12 on one side of the right side wall 111, and the bottom of the yarn guide plate 4 is inserted into the clamping groove 12, and the middle part is abutted against the right side wall 111. Because the yarn guide plate 4 is an important part of the water jet loom, it is mainly used to guide the weft yarn so that it can smoothly pass through various parts from the spool and finally reach the fabric. Therefore, the weft yarn will exert a certain pressure on the yarn guide plate 4 during the traction process. By abutting the yarn guide plate 4 against the right side wall 111, the right side wall 111 provides a certain supporting force to the yarn guide plate 4, thereby avoiding stress concentration at the connection position of the yarn guide plate 4 and the clamping groove 12, and avoiding breakage or disengagement of the yarn guide plate 4 from the clamping groove 12.

[0032] Further, the bottom of the groove 11 is above the clamping groove 12, and an upwardly extending blocking strip 13 is arranged, the blocking strip 13 is arranged opposite to the right side wall 111, the guide plate 4 is clamped between the blocking strip 13 and the right side wall 111, and the fixing stability of the guide plate 4 is improved. In order to ensure the stability of the installation of the guide plate 4, the distance between the blocking strip 13 and the right side wall 111 is equal to the thickness of the guide plate 4, and the front and back lengths of the clamping groove 12 are matched with the bottom of the guide plate 4, so that complete cooperation is realized, and the installed guide plate 4 is prevented from shaking.

[0033] The elastic clamping structure includes a bottom limiting structure and a top limiting structure. The bottom limiting structure includes a bottom limiting hole 41 opened at the bottom of the guide plate 4 and a bottom protrusion 131 arranged on the blocking strip 13 and protruding to the right side wall 111, the bottom protrusion 131 is clamped into the bottom limiting hole 41, and the fixation of the guide plate 4 at the bottom is realized. When the guide plate 4 is inserted into the clamping groove 12, the bottom protrusion 131 is clamped into the bottom limiting hole 41, so that the guide plate 4 is prevented from being pulled out of the clamping groove 12 upward. The bottom protrusion 131 is arranged on the blocking strip 13, the blocking strip 13 is not connected to the two side walls of the groove 11 on both sides, and thus has a certain elastic deformation capacity, facilitating the expansion of the blocking strip 13 to the outside of the clamping groove 12, so as to facilitate the avoidance of the guide plate 4 by the bottom protrusion 131, and the guide plate 4 is prevented from being unable to be inserted into the clamping groove 12.

[0034] Preferably, the top of the bottom protrusion 131 is provided with a downwardly inclined guide slope from the blocking strip 13. When the guide plate 4 is inserted downward, the bottom of the guide plate 4 will press the guide slope of the bottom protrusion 131, forcing the blocking strip 13 to expand to the outside of the clamping groove 12, so that the installation can be completed without manually bending the blocking strip 13, facilitating the insertion and fixation of the guide plate 4.

[0035] The top limiting structure includes a top limiting hole 114 opened at the top of the right side wall 111, and a top protrusion 42 is arranged on the guide plate 4 corresponding to the top limiting hole 114. When the bottom protrusion 131 is clamped into the bottom limiting hole 41, the top protrusion 42 is clamped into the top limiting hole 114, and the fixation of the guide plate 4 at the top is realized. The bottom of the top protrusion is provided with an upwardly inclined guide slope from the guide plate 4, which is also convenient for the insertion and fixation of the guide plate 4.

[0036] As a further optimization, two groups of bottom limiting structures are arranged side by side, and one group of top limiting structures is arranged; the two groups of bottom limiting structures and the one group of top limiting structures enclose a triangle, improving the stability and reliability of the fixation of the guide plate 4.

[0037] Embodiment two:

[0038] As Figure 6As shown, the embodiment is an improvement on the yarn guide plate 4 in Embodiment One, which includes all the technical features of Embodiment One described above, and the improvement is in the overall structure of the yarn guide hole 40 on the yarn guide plate 4. The main problem this improvement addresses is that during the yarn pulling process, the yarn will rub against the yarn guide hole 40, causing the temperature of the yarn guide plate 4 to rise, which will accelerate its wear and tear, reduce its service life, and cause the yarn to heat up, affecting its strength and elasticity. The yarn may become more fragile and prone to breaking under high temperatures, thus reducing the weaving quality.

[0039] The yarn guide hole 40 includes an inner hole 411 and an outer hole 412, with multiple reinforcing ribs 413 arranged between the inner hole 411 and the outer hole 412, forming open-ended heat dissipation channels between adjacent reinforcing ribs 413 for heat dissipation and weight reduction of the yarn guide plate 4. A yarn guide ring 44 is fixedly installed in the inner hole 411 for guiding the yarn. The yarn guide ring 44 is made of ceramic material, thus enhancing its wear resistance. An arc-shaped edge is arranged on the left side of the yarn guide ring 44, which is folded towards the periphery, and the arc-shaped edge is gently transitioned with the yarn guide hole 40 to reduce the friction between the yarn and the yarn guide plate 4. The arc-shaped edge is uniformly provided with heat dissipation holes that communicate with the heat dissipation channels, further improving the heat dissipation effect.

[0040] By arranging the heat dissipation channels at the position of the yarn guide hole 40, the heat dissipation effect is improved, and the temperature of the yarn guide plate 4 is prevented from rising. The arc-shaped edge is arranged on the left side of the yarn guide ring 44, which is folded towards the periphery, i.e. a gradual change design is adopted at the entrance of the yarn guide hole, with the diameter gradually decreasing from the entrance to the inside, to reduce the friction and resistance when the yarn enters.

[0041] Of course, the above description is not a limitation on the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
