Description

Technical Field

[0001] This utility model relates to the field of through-filament filling machine technology, specifically a through-filament filling machine for jacquard machines. Background Technology

[0002] In jacquard weaving, the through yarn, as a key transmission component connecting the jacquard mechanism and the heald frame, needs to maintain a stable trajectory during high-speed reciprocating motion.

[0003] Vibration occurs during the operation of the heddle wire, primarily originating from two sources: firstly, inertial vibration generated by the high-speed reciprocating motion of components such as the heddle rod and heddle eye rod, whose vibration frequency is close to the frequency of the heddle wire movement (20-50Hz), easily leading to resonance; secondly, high-frequency vibration generated by friction between components (such as the contact between the heddle rod and the sleeve). This type of vibration is directly transmitted to the heddle wire through the rigid structure, causing the heddle wire to frequently collide and rub against surrounding components (such as the eyelet wall and adjacent heddle wires) due to violent shaking, resulting in surface wear. In particular, the damage resistance of fine-diameter heddle wires is weaker, and after wear, they are prone to breakage under tension, thereby reducing the service life of the heddle wire. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a filament feeding machine for jacquard machines, which solves the problem of filament damage caused by vibration in existing filament feeding machines. Because traditional devices lack targeted vibration reduction design, the filaments are easily affected by the vibration of the equipment during high-speed movement, resulting in violent shaking. This causes the filaments to rub against each other and collide with surrounding parts, leading to wear or breakage. This damage is more significant for fine-diameter filaments, directly increasing the frequency of filament replacement and production costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a through-wire assembly machine for a jacquard machine, comprising a protective box, wherein the front and rear surfaces of the protective box are provided with sliding grooves communicating with the interior of the protective box;

[0008] The auxiliary component is set on two slides and includes two movable plates. The two movable plates are slidably connected to the inner walls of the two slides respectively. The opposite surfaces of the two movable plates extend into the interior of the protective box. The opposing surfaces of the two movable plates are fixedly connected to connecting plates. The upper surfaces of the two connecting plates are fixedly connected to counterweights.

[0009] Preferably, auxiliary springs are fixedly connected to the lower surfaces of both connecting plates, connecting plates are fixedly connected to the lower surfaces of both auxiliary springs, and dampers are fixedly connected to the upper surfaces of both connecting plates.

[0010] Preferably, the two dampers are located in the inner wall of the corresponding auxiliary spring, and the telescopic ends of the two dampers are fixedly connected to the corresponding connecting plates.

[0011] Preferably, the opposing surfaces of the two movable plates are fixedly connected with heddle rods, and heddle rods are provided with eyelets.

[0012] Preferably, the upper and lower surfaces of the heddle rod are fixedly connected with heddle screws, and the opposing surfaces of the two heddle screws slide through the upper and lower surfaces of the sleeve respectively.

The lower end of the spring is fixedly connected to the inner wall of the sleeve, and the spring is movably sleeved on the outer wall of the heddle rod.

[0014] Preferably, a circular block is fixedly connected to the upper surface of the heddle rod, and a fixing hole is provided on the circular block.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a through-filament feeding machine for jacquard machines, which has the following beneficial effects:

[0017] 1. This jacquard machine uses a thread-feeding machine. When the heald bar drives the heald eye rod to move up and down rapidly, the connecting plate will move synchronously with the moving plate. At this time, the auxiliary spring on the lower surface of the connecting plate will undergo elastic deformation (tension or compression) to absorb the vibration energy generated during the movement. At the same time, the damper on the inner wall of the auxiliary spring will reduce the vibration frequency of the spring through damping, avoid resonance caused by high-frequency vibration of the auxiliary spring, further reduce the vibration amplitude of the overall device, reduce the shaking of the thread due to vibration, protect the thread from damage, and improve the service life of the thread.

[0018] 2. This jacquard machine uses a through-wire assembly machine. The opposing surfaces of the two moving plates are connected to a counterweight through a connecting plate. The weight of the counterweight can balance the weight of components such as the heald rod and heald eye rod, making the up-and-down movement of the heald rod more stable, avoiding movement jamming or deviation caused by uneven weight of components, and improving the stability of the through-wire transmission.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a new technical solution: a jacquard machine thread-forming machine, including a protective box 2, with sliding grooves 13 communicating with the interior of the protective box 2 on both the front and rear surfaces, and an auxiliary component, which is set on the two sliding grooves 13. The auxiliary component includes two movable plates 12, which are slidably connected to the inner walls of the two sliding grooves 13 respectively. The opposing surfaces of the two movable plates 12 extend into the interior of the protective box 2. The opposing surfaces of the two movable plates 12 are fixedly connected to connecting plates 11, and the upper surfaces of the two connecting plates 11 are fixedly connected to counterweights 6.

[0026] Furthermore, auxiliary springs 7 are fixedly connected to the lower surfaces of both connecting plates 11, and connecting plates 8 are fixedly connected to the lower surfaces of both auxiliary springs 7. Dampers 9 are fixedly connected to the upper surfaces of both connecting plates 8.

[0027] Furthermore, the two dampers 9 are located in the inner wall of the corresponding auxiliary spring 7, and the extension and retraction ends of the two dampers 9 are fixedly connected to the corresponding connecting plates 11.

[0028] Furthermore, a heddle rod 10 is fixedly connected to the opposite surfaces of the two movable plates 12, and a heddle rod 10 has a heddle eye.

[0029] Furthermore, heddle rods 3 are fixedly connected to both the upper and lower surfaces of the heddle rod 10, and the opposing surfaces of the two heddle rods 3 slide through the upper and lower surfaces of the sleeve 1 respectively.

[0030] Furthermore, a fixing sleeve 15 is fixedly sleeved on the outer wall of the lower heddle rod 3, and a spring 14 is fixedly connected to the lower surface of the fixing sleeve 15. The lower end of the spring 14 is fixedly connected to the inner wall of the sleeve 1, and the spring 14 is movably sleeved on the outer wall of the heddle rod 3.

[0031] Furthermore, a circular block 5 is fixedly connected to the upper surface of the upper heddle rod 3, and a fixing hole 4 is provided on the circular block 5.

[0032] Furthermore, when using the heddle wire assembly machine of this jacquard machine, the heddle wire first passes through the fixing hole 4 and is embedded in the fixing hole 4, and the heddle wire moves under the drive of the heddle rod 3;

[0033] The heddle rod 3 moves up and down under the drive of the spring 14. The outer wall fixing sleeve 15 of the lower heddle rod 3 moves synchronously with the heddle rod 3. The spring 14 (movably sleeved on the outer wall of the heddle rod 3) undergoes elastic deformation due to the movement of the fixing sleeve 15. When the heddle rod 3 moves downward, the fixing sleeve 15 moves down to compress the spring 14, and the spring 14 stores elastic potential energy. When the external force weakens, the elastic force of the spring 14 pushes the fixing sleeve 15 upward, driving the heddle rod 3 to reset, realizing the reciprocating up and down movement of the heddle rod 3, providing the power basis for the movement of the thread.

[0034] When the heddle rod 3 moves up and down, it drives the heddle eye rod 10, which is fixedly connected to it, to move synchronously. The two ends of the heddle eye rod 10 are connected by moving plates 12. The two moving plates 12 slide in the grooves 13 on the front and rear surfaces of the protective box 2, respectively. The grooves 13 provide guidance for the movement of the moving plates 12, ensuring that the heddle eye rod 10 and the heddle rod 3 move only in the vertical direction, avoiding lateral deviation and ensuring the accuracy of the thread movement trajectory.

[0035] Among them, the opposing surfaces of the two movable plates 12 are connected to the counterweight 6 through the connecting plate 11. The weight of the counterweight 6 can balance the weight of components such as the heddle screw 3 and the heddle eye rod 10, making the up and down movement of the heddle screw 3 more stable, avoiding movement jamming or deviation caused by uneven weight of components, and improving the stability of the wire transmission.

[0036] When the heddle screw 3 drives the heddle eye rod 10 to move up and down rapidly, the connecting plate 11 will move synchronously with the moving plate 12. At this time, the auxiliary spring 7 on the lower surface of the connecting plate 11 will undergo elastic deformation (tension or compression) to absorb the vibration energy generated during the movement. At the same time, the damper 9 on the inner wall of the auxiliary spring 7 will reduce the vibration frequency of the spring through damping, avoid the auxiliary spring 7 from resonating due to high-frequency vibration, further reduce the vibration amplitude of the overall device, reduce the shaking of the wire due to vibration, protect the wire from damage, and improve the service life of the wire.

[0037] The upper heddle rod 3 penetrates the upper surface of the sleeve 1, and the circular block 5 at its top firmly fixes the thread through the fixing hole 4, ensuring that the movement of the thread and the heddle rod 3 are completely synchronized. The lower heddle rod 3, under the continuous elastic force of the spring 14, always maintains a moderate tension on the thread to prevent the thread from loosening and affecting the jacquard accuracy.

[0038] Structural Description:

[0039] Mobile board 12:

[0040] The sliding connection is on the inner wall of the slide groove 13, with the heddle rod 10 connected to the opposite side and the connecting plate 11 connected to the opposite side. It moves up and down with the heddle screw 3, driving the heddle rod to move synchronously. The slide groove 13 ensures that it moves only in the vertical direction.

[0041] Connector plate 11:

[0042] The movable plate 12 is connected to the counterweight 6 and the auxiliary spring 7, which transmit the movement of the movable plate to the counterweight and spring, balance the weight of the component and transmit vibration energy to the shock absorption assembly.

[0043] Counterweight 6:

[0044] Fixed to the upper surface of the connecting plate 11, the heddle screw 3, heddle eye rod 10 and other components are balanced by their own weight, making the heddle screw move up and down more smoothly and avoiding movement jamming.

[0045] Auxiliary spring 7:

[0046] The lower surface of the connecting plate 11 and the connecting fixing plate 8 undergo elastic deformation as the connecting plate 11 moves, absorbing the vibration energy generated by the movement and reducing the overall vibration of the device.

[0047] Connecting fixing plate 8:

[0048] The auxiliary spring 7 and the damper 9 are connected to support the spring and the damper, and the vibration energy is transferred to the damper, which in turn enhances the shock absorption effect in conjunction with the spring.

[0049] Damper 9:

[0050] Located on the inner wall of the auxiliary spring 7, it is connected to the connecting plate 11 and the connecting fixing plate 8 at both ends. Through the damping effect, it reduces the vibration frequency of the spring, avoids resonance, and reduces the vibration amplitude of the device.

[0051] Eyepiece 10:

[0052] Two movable plates 12 are connected. The upper surface has eyelets. As the movable plates move up and down, they drive the thread to move along the trajectory. The eyelets are used to position the thread and ensure accurate transmission.

[0053] Lead screw 3:

[0054] The upper and lower surfaces of the fixed connection eyelet rod 10 are connected by a sleeve 1 at the top and a circular block 5 at the bottom, and a fixed sleeve 15 and a spring 14 are fitted at the bottom. The rod moves up and down repeatedly under the action of the spring, providing power for the through-wire transmission.

[0055] Fixing sleeve 15:

[0056] It is fixedly sleeved on the outer wall of the lower heddle rod 3, and moves up and down with the heddle rod to compress or stretch the spring 14, converting the elastic potential energy of the spring into the motion power of the heddle rod.

[0057] Spring 14:

[0058] The movable sleeve is attached to the outer wall of the lower heddle rod 3, and its two ends are connected to the fixed sleeve 15 and the inner wall of the sleeve 1. When elastic deformation occurs, it stores or releases energy to drive the heddle rod to reciprocate and maintain the continuity of the wire transmission.

[0059] Sleeve 1:

[0060] It accommodates the upper and lower heddle screws 3, provides guidance for the vertical movement of the heddle screws, restricts the lateral offset of the heddle screws, and ensures that they move only in the vertical direction.

[0061] Circular block 5:

[0062] The upper surface of the heddle rod 3 is fixed with a fixing hole 4 for fixing the thread guide wire, ensuring that the thread guide wire moves synchronously with the heddle rod and transmits the motion trajectory to the jacquard mechanism.

[0063] Fixing hole 4:

[0064] The guide wire is inserted into the circular block 5, and is securely fixed therein to prevent it from falling off or shifting during movement, thus ensuring transmission accuracy.

[0065] Slide 13:

[0066] The openings on the front and rear surfaces of the protective box 2 provide sliding space for the movable plate 12, restrict the movement direction of the movable plate, and ensure that the heddle rod and heddle screw move only in the vertical direction to avoid trajectory deviation.
