Description

Technical Field

[0001] This utility model relates to the field of shuttle loom application technology, and in particular to a reinforced heald frame structure for shuttle looms. Background Technology

[0002] During the weaving process on a shuttle loom, the heald frames need to move up and down frequently (especially in high-speed weaving scenarios, the number of reciprocations can reach hundreds per minute). Traditional shuttle loom heald frames generally suffer from the following problems: The connection between the crossbeam and the side brace is prone to loosening due to concentrated stress, which can cause the heald frame to shake during operation and affect the stability of the warp opening. Insufficient connection strength between the heddle rod and the crossbeam can easily lead to displacement or deformation after long-term use, causing the warp yarns to shift in the threading position and reducing the quality of the fabric. The load-bearing capacity of the end face of the helical frame and the drive components (such as the drive hook) is relatively weak. They are prone to breakage or wear under long-term high-frequency loads, which increases equipment maintenance costs and downtime.

[0003] Therefore, there is an urgent need for a reinforced frame structure that can be optimized in terms of connection strength, structural stability, load-bearing capacity, and other aspects. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a reinforced heald frame structure for a shuttle loom. By optimizing the structure of the heald frame, such as the beam connection, heald rod fixing, end face reinforcement, and drive component support, the overall strength and stability of the heald frame are improved, deformation and loosening problems under high-frequency operation are reduced, service life is extended, and weaving accuracy is guaranteed.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a reinforced heald frame structure for a shuttle loom is provided, including an upper crossbeam and a lower crossbeam, both ends of which are bolted with side supports to achieve connection and fixation of the upper and lower crossbeams; Multiple guide plates are bolted to the opposite sides of the upper and lower crossbeams; Both the upper and lower crossbeams are bolted to opposite sides with threaded rods. The end faces of both the upper and lower crossbeams are riveted with reinforcing pads to enhance the strength of the connection between the end faces of the heald frame.

[0006] The present invention is further configured such that both the upper and lower crossbeams are hollow, and the upper crossbeam has multiple openings evenly distributed along its length near the heddle rod.

[0007] Through the above technical solutions, the hollow design can significantly reduce the overall weight of the heald frame while ensuring the structural strength of the crossbeam, thereby reducing the load on the loom drive mechanism and adapting to the requirements of high-speed operation. The evenly spaced openings provide convenient operating space for warp threading and heald installation, while avoiding local structural redundancy in the crossbeam, thus optimizing the structural rationality without weakening the overall strength.

[0008] The present invention is further configured such that: each of the two threaded rods is provided with a reinforcing bolt near its end face, and each of the two reinforcing bolts is threaded with a locking bolt, and the two reinforcing bolts are respectively fixed to the upper crossbeam and the lower crossbeam.

[0009] Through the above technical solution, the reinforcing bolts achieve "through-type" fixation by passing through the heddle rod and the crossbeam. Combined with the threaded locking effect of the locking bolt, it can effectively prevent axial displacement or radial loosening of the heddle rod during high-frequency reciprocating motion, ensure the rigidity of the connection between the heddle rod and the crossbeam, and avoid the warp yarn threading position deviation.

[0010] The present invention is further configured such that: the end faces of the upper crossbeam and the lower crossbeam are provided with reinforcing edges, and the reinforcing edges are L-shaped; the reinforcing edges are connected to the side braces by bolts, and the end faces of the reinforcing bolts are pressed against the reinforcing edges.

[0011] Through the above technical solution, the L-shaped reinforcing edge can simultaneously form a "wrap-around" support for the connection between the beam end face and the side brace, dispersing the lateral force transmitted by the side brace and the axial force transmitted by the reinforcing bolt to a larger area of ​​the beam end face, avoiding local stress concentration; the design of the reinforcing bolt end face pressing against the reinforcing edge further forms a "double locking", which not only fixes the heddle rod, but also enhances the connection stability between the reinforcing edge and the beam.

[0012] The present invention is further configured such that: the upper crossbeam and the lower crossbeam are provided with connection openings near both ends, and the two side supports are respectively inserted into their corresponding connection openings, and one end of each connection opening is circularly positioned.

[0013] The above technical solution, through the "embedded" connection method of inserting the side brace into the connection opening, increases the contact area between the side brace and the crossbeam and improves the connection rigidity compared with the traditional surface bonding connection; the circular design of the connection opening can avoid the stress concentration problem caused by the right angle structure and prevent the crossbeam from cracking or breaking from the edge of the opening under long-term stress.

[0014] The present invention is further configured such that: a drive hook is bolted to the bottom of the lower crossbeam near the end face, and a reinforcing plate is provided at the connection between the two drive hooks and the bottom of the lower crossbeam.

[0015] Through the above technical solution, the drive hook is the core component of the heald frame that receives the driving power of the loom. The reinforcing plate at its connection can increase the contact area of ​​the force, and distribute the driving load from the bolt connection point to the bottom area of ​​the lower crossbeam, so as to avoid the local bolts from slipping or breaking due to excessive force, and ensure the stable transmission of driving power.

[0016] The present invention is further configured such that: the interior of the lower crossbeam and the corresponding positions of the two drive hooks are each welded with connecting screw blocks, which are then connected to the reinforcing plate by bolts.

[0017] Through the above technical solution, the welded connecting bolts inside the lower crossbeam can form a "reverse support" for the reinforcing plate and the drive hook from the inside of the crossbeam, so that the bolt connection forms a "two-way fixing" structure, avoiding the problem of insufficient connection strength caused by the thin wall of the crossbeam when only the outer bolt is used for fixing, and further improving the load-bearing capacity of the drive hook.

[0018] The beneficial effects of this utility model are as follows: 1. The reinforced heald frame structure of the loom proposed in this utility model improves the overall rigidity of the heald frame from multiple dimensions, such as crossbeam connection, functional component fixation, and stress end face protection, through the embedded connection of the side support, double locking of the heald rod, L-shaped reinforcing edge of the end face and bidirectional fixation of the drive component, and effectively solves the problems of loosening and deformation of traditional heald frames. 2. The reinforced heald frame structure of the shuttle loom proposed in this utility model reduces weight through the hollow design of the crossbeam, and optimizes the ease of operation with the opening, thereby reducing the drive load of the shuttle loom without affecting the actual weaving needs such as warp threading.

[0021] 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.

[0022] like Figures 1-3 As shown, a reinforced heald frame structure for a shuttle loom includes an upper crossbeam 1 and a lower crossbeam 2. Both ends of the upper crossbeam 1 and the lower crossbeam 2 are bolted with side supports 3 to connect and fix the upper crossbeam 1 and the lower crossbeam 2. Multiple guide plates 4 are bolted to opposite sides of the upper crossbeam 1 and the lower crossbeam 2. Heald rods 5 are bolted to opposite sides of the upper crossbeam 1 and the lower crossbeam 2. Reinforcing bolts are installed through the heald rods 5 near their end faces, and each of the two reinforcing bolts has a threaded locking block 8. The two reinforcing bolts are fixed to the upper crossbeam 1 and the lower crossbeam 2 respectively. The reinforcing bolts are fixed to the crossbeams through the heald rods 5 in a "through-type" manner. With the threaded locking effect of the locking block 8, the axial displacement or radial loosening of the heald rods 5 during high-frequency reciprocating motion can be effectively prevented, ensuring the rigidity of the connection between the heald rods 5 and the crossbeams and avoiding the deviation of the warp yarn threading position. Both the upper crossbeam 1 and the lower crossbeam 2 are hollow, and the upper crossbeam 1 has multiple openings 6 evenly spaced along its length near the heald bar 5. The hollow design can significantly reduce the overall weight of the heald frame while ensuring the structural strength of the crossbeam, thus reducing the load on the loom drive mechanism and meeting the requirements of high-speed operation. The evenly spaced openings 6 provide convenient operating space for warp threading and heald installation, and avoid local structural redundancy of the crossbeam. The structural rationality is optimized without weakening the overall strength. The end faces of the upper crossbeam 1 and the lower crossbeam 2 are riveted with reinforcing pads 7 to enhance the strength of the connection between the end faces of the heald frame.

[0023] like Figure 1 , Figure 4 and Figure 5As shown, both the upper crossbeam 1 and the lower crossbeam 2 have reinforcing edges 9 on their end faces, and these reinforcing edges 9 are L-shaped. The reinforcing edges 9 are bolted to the side brace 3. The L-shaped reinforcing edges 9 simultaneously provide "wrapping" support to both the crossbeam end face and the connection point of the side brace 3, dispersing the lateral force transmitted by the side brace 3 and the axial force transmitted by the reinforcing bolts to a larger area of ​​the crossbeam end face, avoiding localized stress concentration. Simultaneously, the end face of the reinforcing bolt abuts against the reinforcing edge 9. This design further forms a "double locking," both fixing the mandrel 5 and reinforcing the crossbeam. To ensure the stability of the connection between the strong side 9 and the crossbeam, both the upper crossbeam 1 and the lower crossbeam 2 have connection openings 11 near their ends. The side brace 3 is inserted into the connection opening 11 in an "embedded" connection method. Compared with the traditional surface bonding connection, this increases the contact area between the side brace and the crossbeam, and improves the connection rigidity. The two side braces 3 are respectively inserted into their corresponding connection openings 11. One end of each connection opening 11 is circular. The circular design of the connection opening 11 can avoid the stress concentration problem caused by the right angle structure and prevent the crossbeam from cracking or breaking from the edge of the opening under long-term stress. The bottom of the lower crossbeam 2 is bolted with drive hooks 10 near the end face. A reinforcing plate is installed at the connection point between the two drive hooks 10 and the bottom of the lower crossbeam 2. The drive hooks 10 are the core components of the heald frame receiving the driving power of the loom. The reinforcing plate at their connection increases the contact area, distributing the driving load from the bolt connection point to the bottom area of ​​the lower crossbeam 2. This prevents local bolts from slipping or breaking due to excessive force, ensuring stable transmission of driving power. Connecting bolt blocks are welded to the corresponding positions of the two drive hooks 10 inside the lower crossbeam 2 and bolted to the reinforcing plate. The welded connecting bolt blocks inside the lower crossbeam 2 provide "reverse support" to the reinforcing plate and drive hooks 10 from the inside of the crossbeam, creating a "bidirectional fixing" structure for the bolt connection. This avoids insufficient connection strength due to the thin wall of the crossbeam when only the outer bolts are used for fixing, further enhancing the load-bearing capacity of the drive hooks 10.

[0024] In use, the guide plate 4 cooperates with the guide rail of the loom to ensure the stability of the heddle frame's up-and-down reciprocating motion. The warp yarns are passed through the opening 6 of the upper beam 1 to the heddle wires of the heddle rod 5. When the loom drives the heddle frame to move at high frequency through the drive hook 10, the embedded connection of the side support 3, the double locking of the heddle rod 5, the end face reinforcement edge 9, and the bidirectional fixing structure of the drive hook 10 work together to effectively resist the inertial force and load during the movement, prevent the structure from loosening or deforming, ensure the accurate opening of the warp yarns, and improve the weaving quality and efficiency.
