Description

Technical Field

[0001] This utility model relates to the field of gauze heddle frame application technology, and in particular to a connection mechanism for the upper and lower beams of an anti-loosening gauze heddle frame. Background Technology

[0002] The leno heald frame is one of the core components of textile machinery, primarily used to guide the warp yarns according to a preset pattern, thereby forming a specific fabric structure. During textile production, the leno heald frame needs to withstand high-frequency reciprocating motion and warp tension over extended periods; its structural stability directly affects the weaving quality and production efficiency. The connection points between the upper and lower crossbeams and the side bars are critical stress points for the leno heald frame, and their connection reliability is of paramount importance.

[0003] In existing technologies, the upper and lower beams and side rods of a tulle heald frame are typically fixed using a single bolt connection or a simple plug-in method. However, under long-term high-frequency vibration and repeated stress conditions, problems such as bolt loosening and increased gaps in the plug-in fit are prone to occur at the connection points. This leads to relative displacement between the upper and lower beams and the side rods, which not only affects the accuracy of warp yarn guidance and causes more fabric defects, but may also cause the connection points to break in severe cases, leading to equipment downtime, reduced production efficiency, and increased maintenance costs. Therefore, this utility model proposes an anti-loosening connection mechanism for the upper and lower beams of a tulle heald frame. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a connection mechanism for the upper and lower beams of a heddle frame that prevents loosening. By optimizing the connection structure design, the connection tightness and anti-loosening ability between the upper and lower beams and the side rods are improved, ensuring the structural stability of the heddle frame under long-term high-frequency working conditions.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a mechanism for connecting the upper and lower beams of a heddles frame to prevent loosening is provided, including an upper beam and a lower beam. Side rods are symmetrically inserted into the end faces of the upper beam and the lower beam. Connecting reinforcements are provided between the two side rods and the upper beam and the lower beam respectively, so as to achieve a tight connection between the side rods and the upper beam and the lower beam using the connecting reinforcements. Both the upper and lower crossbeams are riveted with threaded rods on opposite sides, and both the upper and lower crossbeams are bolted with guide blocks on opposite sides. The bottom of the lower crossbeam is bolted with drive components near both ends.

[0006] The present invention is further configured such that two sets of guide blocks located on the upper and lower crossbeams are arranged in a relatively alternating manner.

[0007] By adopting the above technical solution and the design of relatively alternating guide blocks, the guiding force on the gauze heald frame during movement can be more balanced, avoiding movement deviation caused by concentrated force on one side. At the same time, the alternating structure can reduce frictional interference between guide surfaces, improve smoothness of movement, and indirectly reduce the risk of loosening of the connection parts due to uneven force.

[0008] The present invention is further configured such that: both ends of the side rod are equipped with connecting parts, and are respectively inserted into the corresponding upper and lower crossbeams through the connecting parts.

[0009] Through the above technical solution, the side bar is inserted into the upper and lower crossbeams through a specially designed connecting part. The connecting part can form a precise position with the internal structure of the upper and lower crossbeams, increasing the contact area between the two. Compared with the traditional direct insertion method, it can effectively improve the initial stability of the connection, provide a reliable foundation for subsequent reinforcement, and prevent the side bar from radially moving within the upper and lower crossbeams.

[0010] The present invention is further configured such that: the connecting reinforcement component includes a sealing plate, and a reinforcing plate, a bracket and a positioning block are fixedly connected to one side of the sealing plate from top to bottom.

[0011] Through the above technical solution, the connecting reinforcement component adopts an integrated structural design of sealing plate, reinforcing plate, clamp, and positioning block, with each component working together to form a multi-layered reinforcement system. The sealing plate can seal and protect the connection parts, preventing dust, lint, and other impurities from entering the connection gap and affecting the fitting accuracy; the reinforcing plate, clamp, and positioning block reinforce the connection between the side rod and the upper and lower crossbeams from different dimensions, achieving multi-directional limiting and improving the overall connection strength.

[0012] The present invention is further configured such that: the reinforcing plate is inserted into the interior of the upper and lower crossbeams and is fixed by two bolts, one of which extends to the end of the connection part.

[0013] With the above technical solution, after the reinforcing plate is inserted into the upper and lower crossbeams, it is fixed by double bolts. This not only makes the reinforcing plate and the upper and lower crossbeams firmly connected, but also allows one of the bolts to directly press against the connection part of the side rod, forming an axial clamping force. This effectively eliminates the connection gap and prevents the connection part from loosening axially in the upper and lower crossbeams. At the same time, the double bolt design can distribute the force and improve the fatigue resistance of the connection.

[0014] The present invention is further configured such that the card holder is configured in a claw-like structure and is inserted into the card slots symmetrically opened on both sides of the connecting part.

[0015] Through the above technical solution, the claw-shaped clamp and the slot on the connecting part form a snap-fit ​​engagement. The claw-shaped structure can clamp and limit the connecting part from both sides, restricting the radial displacement and rotation of the connecting part. Combined with the axial pressing action of the bolt, it forms a dual fixing effect of axial pressing and radial clamping, which significantly improves the anti-loosening ability of the connecting part and avoids relative displacement caused by vibration.

[0016] The present invention is further configured such that: a reinforcing plate is installed inside the lower crossbeam near the driving component, and the reinforcing plate is connected to the driving component by bolts.

[0017] Through the above technical solution, the drive component is the power transmission component that drives the movement of the heald frame, and the force is concentrated at the connection point between it and the lower crossbeam. The addition of the reinforcing plate can increase the contact area between the drive component and the lower crossbeam, disperse the load, and prevent the lower crossbeam from deforming or the connecting bolts from loosening due to excessive local stress, thus ensuring the stability and reliability of power transmission.

[0018] The beneficial effects of this utility model are as follows: 1. The anti-loosening heddle frame upper and lower beam connection mechanism proposed in this utility model sets up connecting reinforcement components between the side rod and the upper and lower crossbeams. Utilizing the synergistic effect of the sealing plate, reinforcement plate, claw-shaped bracket, and positioning block, combined with double bolt fixing and slot buckle connection, a multi-reinforcement structure of axial compression, radial clamping, and sealing protection is formed. This effectively avoids the loosening problem caused by high-frequency vibration in traditional connection methods, significantly improves the tightness and fatigue resistance of the connection parts, and ensures the long-term stable operation of the heddle frame. 2. The anti-loosening heald frame upper and lower beam connection mechanism proposed in this utility model optimizes the relative and alternating distribution design of the guide blocks and adds a reinforcing plate at the drive component. This not only ensures the guiding accuracy and force balance during the movement of the heald frame, but also enhances the structural strength of the power transmission part, reduces local stress concentration, and lowers the risk of component deformation and breakage. At the same time, the overall structure design is reasonable and the assembly is convenient, which helps to reduce maintenance costs and improve textile production efficiency and fabric weaving quality.

[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 Figure 1 and Figure 4 As shown, an anti-loosening gauze heddle frame upper and lower beam connection mechanism includes an upper crossbeam 1 and a lower crossbeam 2. Side rods 3 are symmetrically inserted into the end faces of the upper crossbeam 1 and the lower crossbeam 2. Both ends of the side rods 3 are equipped with connecting parts 31, and are respectively inserted into the corresponding upper crossbeam 1 and lower crossbeam 2 through the connecting parts 31. The side rods 3 are connected to the upper and lower crossbeams through the specially designed connecting parts 31. The connecting parts 31 can form a precise positioning with the internal structure of the upper and lower crossbeams, increasing the contact area between the two. Compared with the traditional direct insertion method, it can effectively improve the initial stability of the connection, provide a reliable foundation positioning for subsequent reinforcement, and prevent the side rods 3 from radially moving within the upper and lower crossbeams.

[0023] like Figure 2 and Figure 3 As shown, two side rods 3 are respectively connected to the upper crossbeam 1 and the lower crossbeam 2 with connecting reinforcement components 7. These components secure the connection between the side rods 3 and the upper and lower crossbeams 1 and 2. The connecting reinforcement component 7 includes a sealing plate 71. On one side of the sealing plate 71, from top to bottom, a reinforcing plate 72, a bracket 73, and a positioning block 74 are sequentially fixedly connected. The connecting reinforcement component 7 adopts an integrated structural design of the sealing plate 71, reinforcing plate 72, bracket 73, and positioning block 74, with each component working together to form a multi-layered reinforcement system. The sealing plate 71 seals and protects the connection points, preventing dust, lint, and other impurities from entering the connection gap and affecting the fitting accuracy. The reinforcing plate 72, bracket 73, and positioning block 74 reinforce the connection between the side rods 3 and the upper and lower crossbeams from different dimensions, achieving multi-directional limiting and improving the overall connection strength. The reinforcing plate 72 is inserted into the upper crossbeam 1 and the lower crossbeam 2 and fixed by two bolts. One bolt extends to the end of the connecting part 31. After the reinforcing plate 72 is inserted into the upper and lower crossbeams, the double-bolt fixing method not only forms a firm connection between the reinforcing plate 72 and the upper and lower crossbeams, but also allows one bolt to directly press against the connecting part 31 of the side rod 3, forming an axial clamping force. This effectively eliminates the connection gap and prevents the connecting part 31 from loosening axially within the upper and lower crossbeams. At the same time, the double-bolt design can distribute the force and improve the connection. For fatigue resistance, the clip 73 is designed with a claw-like structure. The clip 73 is inserted into the symmetrical slots 32 on both sides of the connecting part 31. The claw-like clip 73 and the slots 32 on the connecting part 31 form a snap-fit ​​engagement. The claw-like structure can clamp and limit the connecting part 31 from both sides, restricting the radial displacement and rotation of the connecting part 31. Combined with the axial clamping action of the bolt, it forms a dual fixing effect of axial clamping and radial clamping, which significantly improves the anti-loosening ability of the connecting part and avoids relative displacement caused by vibration.

[0024] like Figure 1 and Figure 4 As shown, the upper crossbeam 1 and the lower crossbeam 2 are riveted with heald rods 4 on opposite sides, and guide blocks 5 are bolted to opposite sides of the upper crossbeam 1 and the lower crossbeam 2. The two sets of guide blocks 5 on the upper crossbeam 1 and the lower crossbeam 2 are arranged in a relatively alternating manner. The design of the relatively alternating distribution of guide blocks 5 can make the guiding force on the gauze heald frame more balanced during the movement, avoid the movement deviation caused by the concentration of force on one side, and at the same time, the alternating distribution structure can reduce the frictional interference between the guide surfaces, improve the smoothness of movement, and indirectly reduce the risk of loosening caused by uneven force on the connection parts. The bottom of the lower crossbeam 2 is bolted to the two ends of the drive component 6. The interior of the lower crossbeam 2 is installed near the drive component 6, and the reinforcing plate 61 is installed on the drive component 6 by bolts. The drive component 6 is the power transmission component that drives the movement of the gauze heald frame. The force is concentrated at the connection part with the lower crossbeam 2. The reinforcement plate 61 increases the contact area between the drive component 6 and the lower crossbeam 2, disperses the load, and prevents the lower crossbeam 2 from deforming or the connecting bolts from loosening due to excessive local stress, thus ensuring the stability and reliability of power transmission.

[0025] In use, the driving component 6 drives the lower crossbeam 2 and the overall structure to reciprocate. The guide block 5 plays a guiding and limiting role, and the heddle rod 4 guides the movement of the warp yarns. The reinforcing plate 72 and the bracket 73 of the connecting reinforcement component 7 cooperate with the bolts to effectively prevent loosening between the side rod 3 and the upper and lower crossbeams. The reinforcing plate 61 ensures the stress stability of the connection part of the driving component 6. The overall structure achieves the requirements of anti-loosening and high stability.

[0026] 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.
