Description

Technical Field

[0001] This utility model relates to the field of textile machinery application technology, and in particular to an externally mounted shuttle frame structure for a shuttle loom. Background Technology

[0002] During the operation of a shuttle loom, the heald frame is a key component for realizing the warp opening. Its function is to drive the warp yarns up and down to form the shed through which the weft yarns pass.

[0003] Traditional heddle frames are usually located inside the loom. This built-in structure requires disassembling part of the loom's outer shell and internal components when inspecting, maintaining, or replacing the heddle wires. This operation is cumbersome, time-consuming, and seriously affects production efficiency. Therefore, this utility model proposes an external heddle frame structure for the loom. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an external heddle frame structure for a shuttle loom. It adopts an external design, which facilitates inspection and maintenance, while ensuring the stability of the heddle frame movement, reducing impact, and extending the service life of the equipment.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing an external heddle frame structure for a shuttle loom, including an upper beam assembly and a lower beam assembly, wherein side plates are bolted to both ends of the upper beam assembly and the lower beam assembly to connect and fix the end faces of the upper beam assembly and the lower beam assembly; The upper beam assembly and the lower beam assembly are bolted together at the middle position with reinforcing members to work with the two side plates to enhance the overall strength of the heald frame structure.

[0006] The present invention is further configured such that: both the upper beam assembly and the lower beam assembly include a crossbeam with a U-shaped cross-section; one side of the crossbeam is bolted to multiple brackets, and a heddle rod is riveted to the brackets; slots are opened at the middle of both ends of the crossbeam, and reinforcing blocks are riveted to both sides of the slots on the inner wall of the crossbeam; a connecting frame is bolted to the reinforcing block near the heddle rod, and the connecting frame is bolted to one end of the heddle rod; and a central support reinforcing block is riveted to the middle of the crossbeam.

[0007] Through the above technical solution, the upper beam assembly and the lower beam assembly maintain the same structural composition, with their core load-bearing component being a U-shaped cross-section beam. The U-shaped structural design not only achieves lightweighting while ensuring structural rigidity, but also provides a stable reference surface for the subsequent installation of other components.

[0008] On one side of the crossbeam, multiple brackets are fixed by bolts. These brackets serve as intermediate connectors and are riveted to the heddle rod, thus stably assembling the heddle rod onto the crossbeam. As a key component for warp threading, the installation stability of the heddle rod directly affects the accuracy of the warp opening. The bolted connection between the brackets and the crossbeam, and the riveted connection with the heddle rod, provide double assurance for this stability.

[0009] To further enhance the structural strength of the beam, especially to address the issue of concentrated stress at both ends, slots are cut at the middle of both ends of the beam, and reinforcing blocks are riveted to both sides of the slots on the inner wall of the beam. The slots provide space for the connection between the beam and the side plates, while the reinforcing blocks effectively distribute the stress at the slots, preventing deformation of the beam ends due to stress.

[0010] The reinforcing block near the heddle rod is bolted to a connecting frame, the other end of which is also bolted to the end of the heddle rod. This design provides auxiliary support between the heddle rod and the crossbeam, further enhancing the heddle rod's anti-sway capability during high-speed movement and ensuring the stability of the warp yarn movement.

[0011] In addition, a central bracing reinforcement block is riveted to the middle of the crossbeam. Since the crossbeam is long and narrow, the middle area is prone to bending stress due to its large span. The central bracing reinforcement block can specifically enhance the rigidity of the middle of the crossbeam, avoiding structural deformation caused by stress accumulation after long-term use, thereby ensuring the service life and operational accuracy of the entire heel frame structure.

[0012] The present invention is further configured such that: a plurality of support grooves are evenly provided on the top of the crossbeam, and the plurality of supports are respectively bolted to the inside of the support grooves.

[0013] The above technical solution facilitates the placement of multiple supports into the support slots during installation, thereby achieving stable installation and fixation, which in turn ensures stable fixation of the heald rod and improves stability during the spinning process.

[0014] The present invention is further configured such that: a central support groove communicating with an adjacent bracket groove is provided at the top and middle position of the crossbeam, and the central support reinforcing block is located inside the central support groove and is fixed by riveting.

[0015] The above technical solution facilitates the fitting of the central support reinforcement block into the central support groove during installation, thereby achieving a secure riveting installation of the central support reinforcement block.

[0016] The present invention is further configured such that: the crossbeam inside the lower beam assembly has multiple external hook grooves on the opposite wall of the heddle rod, and hooks are bolted inside the external hook grooves.

[0017] The above technical solution facilitates the connection of the hook bolt to the inside of the outer hook groove, thereby achieving stable installation and fixation of the hook.

[0018] The present invention is further configured such that the two reinforcing blocks are connected to the side plate by bolts.

[0019] The above technical solution facilitates the connection and fixation of the two side plates using bolts on the reinforcing block during installation, and achieves stable connection and fixation under the adaptability of the slot.

[0020] The beneficial effects of this utility model are as follows: The present invention proposes an external heddle frame structure for a shuttle loom. The external design facilitates inspection and maintenance, while ensuring the stability of the heddle frame movement, reducing impact, and extending the service life of the equipment.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] like Figures 1-6As shown, an externally mounted heald frame structure for a shuttle loom includes an upper beam assembly 1 and a lower beam assembly 2. Side plates 3 are bolted to both ends of both the upper beam assembly 1 and the lower beam assembly 2 to connect and fix their end faces. The upper beam assembly 1 and the lower beam assembly 2 are structurally identical, with their core load-bearing component being a U-shaped cross-section beam 11. This U-shaped structure design achieves lightweighting while ensuring structural rigidity and provides a stable reference surface for the subsequent installation of other components.

[0025] On one side of the crossbeam 11, multiple brackets 12 are fixed by bolts. These brackets 12 serve as intermediate connecting parts and are riveted to the heddle rod 13, thereby stably assembling the heddle rod 13 onto the crossbeam 11. Multiple bracket slots 111 are evenly provided on the top of the crossbeam 11. The multiple brackets 12 are bolted to the inside of the bracket slots 111, so that when installing multiple brackets 12, they can be placed into the bracket slots 111, thereby achieving stable installation and fixation, thus achieving stable fixation of the heddle rod 13 and improving stability during the spinning process. As a key component for warp yarn threading, the installation stability of the heddle rod 13 directly affects the accuracy of the warp yarn opening. The bolted connection between the brackets 12 and the crossbeam 11 and the riveted connection with the heddle rod 13 doubly ensure this stability.

[0026] To further enhance the structural strength of the crossbeam 11, especially to address the issue of concentrated stress at both ends, slots 14 are provided at the midpoint of both ends of the crossbeam 11. Reinforcing blocks 15 are riveted to both sides of the slots 14 on the inner wall of the crossbeam 11. The two reinforcing blocks 15 are bolted to the side plates 3, facilitating connection and fixation during installation of the two side plates 3 using the bolts on the reinforcing blocks 15, and achieving stable connection and fixation under the adaptive effect of the slots 14. The slots 14 provide space for the connection between the crossbeam 11 and the side plates 3, while the reinforcing blocks 15 effectively disperse the stress at the slots 14, preventing deformation of the ends of the crossbeam 11 due to stress.

[0027] The reinforcing block 15 near the heddle rod 13 is also bolted to a connecting frame 16, and the other end of the connecting frame 16 is also bolted to the end of the heddle rod 13. This design forms an auxiliary support between the heddle rod 13 and the crossbeam 11, further improving the anti-sway capability of the heddle rod 13 during high-speed movement and ensuring the stability of the warp yarn movement.

[0028] In addition, a central support reinforcement block 17 is riveted to the middle of the crossbeam 11. A central support groove 112, which communicates with the adjacent support groove 111, is opened at the top and middle of the crossbeam 11. The central support reinforcement block 17 is located inside the central support groove 112 and is fixed by riveting. This makes it easy for the central support reinforcement block 17 to fit into the central support groove 112 during installation, thus achieving a firm riveting installation of the central support reinforcement block 17. Since the crossbeam 11 is long and narrow, the middle area is prone to bending stress due to its large span. The central support reinforcement block 17 can specifically enhance the rigidity of the middle part of the crossbeam 11, avoiding structural deformation caused by stress accumulation after long-term use, thereby ensuring the service life and operational accuracy of the entire frame structure.

[0029] The upper beam assembly 1 and the lower beam assembly 2 are bolted together with a reinforcing member 4 in the middle position to cooperate with the two side plates 3 to strengthen the overall strength of the heddle frame structure. The crossbeam 11 inside the lower beam assembly 2 has multiple external hook grooves 113 on the opposite wall to the heddle rod 13, and hooks 18 are bolted inside the external hook grooves 113, so that the hooks 18 can be bolted into the inside of the external hook grooves 113, thereby achieving stable installation and fixation of the hooks 18.

[0030] In use, this utility model adopts an external design for the entire heald frame structure. When inspection, maintenance, or replacement of heald yarns is required, it is not necessary to disassemble parts of the outer shell and internal components of the loom. This simplifies operation, effectively saves time, and improves production efficiency. At the same time, the side plates 3 at both ends of the upper beam assembly 1 and the lower beam assembly 2, as well as the reinforcing member 4 in the middle, together with the reinforcing block 15 and the central support reinforcing block 17 on the crossbeam 11, can significantly enhance the strength of the entire structure, ensure the stability of the heald frame movement, reduce impact, and extend the service life of the equipment.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
