Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, and in particular to a pressing and positioning device for jacquard fabric weaving. BACKGROUND

[0002] Jacquard fabric weaving is a complex and delicate process that forms a predetermined pattern on the fabric through special weaving techniques. Jacquard weaving is done on a jacquard loom, a machine that can control the rise and fall of each warp thread according to a design pattern, thus forming complex patterns on the fabric. Jacquard looms can be traditional mechanical or modern electronic, the latter providing higher precision and flexibility.

[0003] In related technologies, please refer to the Chinese utility model patent with the authorization announcement number CN205529258U, which discloses a jacquard machine, which includes a transmission shaft, a driven shaft, a runner and a lever; the jacquard machine also includes a knife, two or more knife holders and two or more rocker arms; the two or more rocker arms are arranged on the driven shaft at intervals, and each group of rocker arms includes a first rocker arm and a second rocker arm; the knife holder is connected with the rocker arm, and two knife holders are arranged at intervals; the two ends of the knife are connected with the two knife holders respectively.

[0004] However, during the operation of the above-mentioned jacquard machine, the woven jacquard fabric is easily affected by the external environment and deviates or wrinkles after being guided out of the jacquard machine, thus adversely affecting the subsequent weaving work of the jacquard machine. CONTENT OF THE UTILITY MODEL

[0005] In order to ensure the stable and continuous weaving of the jacquard fabric, the present application provides a pressing and positioning device for jacquard fabric weaving.

[0006] The pressing and positioning device for jacquard fabric weaving provided by the present application adopts the following technical scheme:

[0007] A pressing and positioning device for jacquard fabric weaving, comprising a rack and a cloth outlet table, the rack is arranged on the body of the jacquard machine, the cloth outlet table is arranged on the rack, the woven fabric on the body of the jacquard machine is guided along the cloth outlet table, a stabilizing mechanism for stabilizing the fabric on the cloth outlet table is arranged on the rack, and the stabilizing mechanism comprises:

[0008] A stabilizing plate is arranged on the rack;

[0009] Two stabilizing wheels are arranged on the stabilizing plate, and the two stabilizing wheels are arranged on the stabilizing plate in a rotating and sliding manner, and the two stabilizing wheels are respectively located on both sides of the width direction of the fabric;

[0010] A moving assembly is arranged on the stabilizing plate and used to drive the stabilizing wheels to move, and the stabilizing wheels are in contact with the surface of the fabric under the action of the moving assembly.

[0011] By adopting the above technical solution, after the fabric woven by the jacquard machine is guided onto the fabric table, the stabilizing plate is rotated. Under the action of gravity, the stabilizing plate drives two stabilizing wheels to press firmly onto the fabric. Thus, the stabilizing plate and stabilizing wheels work together to flatten the fabric while ensuring continuous movement and delivery. This reduces the probability of the fabric flipping or wrinkling under the influence of the external environment, allowing the jacquard machine to maintain stable weaving operations. At the same time, by controlling the moving components to drive the two stabilizing wheels, the movement speed of the fabric on both sides can be adjusted by adjusting the contact area between the stabilizing wheels and the fabric. This corrects any deviation in the fabric, ensuring that the fabric is uniform and neat in subsequent weaving processes.

[0012] Optionally, the moving component includes:

[0013] A movable block is slidably mounted on a stabilizing plate, and a stabilizing wheel is rotatably mounted on the movable block;

[0014] A movable lead screw, which is rotatably mounted on a stabilizing plate and threadedly connected to a movable block;

[0015] A rotating component is mounted on a stabilizing plate and is used to drive the moving lead screw to rotate.

[0016] By adopting the above technical solution, the rotating component starts and drives the moving screw to rotate, the moving screw rotates and drives the moving block to move, and the moving block moves and drives the stabilizing wheel to move, thereby completing the work of moving the stabilizing wheel on the stabilizing plate.

[0017] Optionally, the rotating member includes:

[0018] A rotating rod, which is rotatably mounted on a stabilizing plate;

[0019] A rotating motor is mounted on a stabilizing plate.

[0020] The first bevel gear is mounted on the moving lead screw;

[0021] The second bevel gear is mounted on the rotating rod and meshes with the first bevel gear.

[0022] The third bevel gear is disposed on the end of the rotating rod away from the second bevel gear;

[0023] The fourth bevel gear is mounted on the output shaft of the rotating motor and meshes with the third bevel gear.

[0024] By adopting the above technical solution, the rotating motor starts and drives the fourth bevel gear to rotate, the fourth bevel gear rotates and drives the third bevel gear to rotate, the third bevel gear rotates and drives the rotating rod to rotate, the rotating rod rotates and drives the second bevel gear to rotate, the second bevel gear rotates and drives the first bevel gear to rotate, and the first bevel gear rotates and drives the moving lead screw to rotate, thereby realizing the rotation of the moving lead screw by controlling the rotating motor.

[0025] Optionally, the two sets of moving components used to drive the two stabilizing wheels share a single rotating motor. The fourth bevel gear on the rotating motor meshes with the third bevel gear in both sets of moving components, and the threads of the moving lead screws in the two sets of moving components are reversed.

[0026] By adopting the above technical solution, the moving screws in the two sets of moving components are set in opposite directions, and the third bevel gears in the two sets of moving components share the fourth bevel gear of a rotating motor. Thus, by controlling a single rotating motor, the two stabilizing wheels can be driven to move synchronously in opposite directions, making the operation of the two stabilizing wheels easier to control and simpler and more efficient.

[0027] Optionally, the frame is equipped with two infrared detectors, which are located on opposite sides of the fabric width. The frame is also equipped with a controller, which is electrically connected to the rotating motors of the two infrared detectors.

[0028] By adopting the above technical solution, two infrared detectors are installed on the frame. The two infrared detectors emit infrared rays to sense and detect the two sides of the fabric respectively. When the infrared detectors detect the fabric deviation, the controller can control the rotating motor to start and correct the fabric deviation.

[0029] Optionally, the moving block is provided with an adjustment mechanism for adjusting the distance between the two stabilizing wheels, the adjustment mechanism comprising:

[0030] An adjusting block, which is horizontally slidably mounted on a movable block;

[0031] Two fixed blocks are horizontally slidably mounted on the adjusting block and located on both sides of the moving block, respectively;

[0032] Two sets of drive components are provided, both of which are mounted on the adjusting block. Two fixed blocks clamp the moving block under the action of the two sets of drive components.

[0033] By adopting the above technical solution, two sets of drive components are used to control the two fixed blocks to move away from each other, so that the two fixed blocks are separated from the moving block. This allows the moving adjustment block to drive the stabilizing wheel to move horizontally, thereby adjusting the distance between the two stabilizing wheels. After the two stabilizing wheels move to the target position, the two sets of drive components are used to drive the two fixed blocks to clamp the moving block, thereby fixing the position of the adjustment block, thus completing the movement and fixing of the stabilizing wheel position.

[0034] Optionally, the driving component includes:

[0035] A drive spring is provided, which is mounted on the adjusting block and connected to the fixed block. The fixed block is pressed against the moving block under the action of the drive spring.

[0036] A drive rod is horizontally slidably mounted on an adjusting block. One end of the drive rod is connected to a fixed block, and the other end of the drive rod extends out of the adjusting block.

[0037] By adopting the above technical solution, pulling the drive rod causes the fixed block to compress the drive spring and move, which can separate the fixed block from the moving block. Then the adjusting block can move freely. When the adjusting block moves to the target position, the drive rod is released, and the fixed block is pressed against the moving block under the action of the drive spring, thereby fixing the position of the adjusting block and completing the movement of the fixed block.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. By rotating the stabilizing plate, the stabilizing plate drives the two stabilizing wheels to press the fabric under the action of gravity. Thus, the stabilizing plate and stabilizing wheels work together to flatten the fabric while ensuring that the fabric can continue to move and be guided out. This reduces the probability of the fabric turning over or wrinkling under the influence of the external environment, so that the jacquard machine can maintain stable weaving operation.

[0040] 2. By controlling the moving component to drive the two stabilizing wheels to move, the movement speed of the fabric on both sides can be adjusted by adjusting the contact area between the stabilizing wheels and the fabric, thereby correcting the offset fabric and ensuring that the fabric is uniform and neat in the subsequent weaving process.

[0041] 3. By pulling the drive rod to move the fixed block and compress the drive spring, the fixed block can be separated from the moving block. Then the adjusting block can be moved freely. When the adjusting block moves to the target position, the drive rod is released, and the fixed block is pressed against the moving block under the action of the drive spring, thereby fixing the position of the adjusting block and completing the movement of the fixed block.

[0046] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0047] This application discloses a pressing and positioning device for weaving jacquard fabrics.

[0048] Reference Figure 1 The pressing and positioning device for jacquard fabric weaving includes a frame 1 and a fabric output table 11. The frame 1 is fixedly installed on the jacquard machine body. The fabric output table 11 is fixedly installed on the frame 1. The fabric woven on the jacquard machine body is led out along the fabric output table 11. The frame 1 is provided with a stabilizing mechanism 2 for stabilizing the fabric on the fabric output table 11.

[0049] Reference Figure 1 and Figure 2 The stabilizing mechanism 2 includes a stabilizing plate 21, two stabilizing wheels 22, and a moving assembly 23. The stabilizing plate 21 is rotatably mounted on the frame 1. An installation cavity 24 is formed inside the stabilizing plate 21. Two sliding holes communicating with the installation cavity 24 are formed on the lower surface of the stabilizing plate 21. The two stabilizing wheels 22 are slidably and rotatably mounted on the stabilizing plate 21 and are respectively located within the two sliding holes, with the two stabilizing wheels 22 located on opposite sides of the fabric width direction. The moving assembly 23 is disposed on the stabilizing plate 21 and is used to drive the stabilizing wheels 22 to move, and the stabilizing wheels 22 contact the fabric surface under the action of the moving assembly 23.

[0050] Reference Figure 1 and Figure 2The moving assembly 23 includes a moving block 25, a moving lead screw 26, and a rotating component 27. The moving block 25 is slidably mounted on the stabilizing plate 21 along the direction of entering and exiting the sliding hole. The stabilizing wheel 22 is rotatably disposed at the bottom end of the moving block 25. The moving lead screw 26 is rotatably mounted on the top wall of the mounting cavity 24 of the stabilizing plate 21 and is threadedly connected to the moving block 25. The rotating component 27 is disposed on the stabilizing plate 21 and is used to drive the moving lead screw 26 to rotate.

[0051] Reference Figure 2 The rotating component 27 includes a rotating rod 31, a rotating motor 32, a first bevel gear 33, a second bevel gear 34, a third bevel gear 35, and a fourth bevel gear 36. The rotating rod 31 is rotatably mounted on the inner wall of the mounting cavity 24. The first bevel gear 33 is fixedly mounted on the top of the moving lead screw 26. The second bevel gear 34 and the third bevel gear 35 are respectively fixedly mounted at both ends of the rotating rod 31. The second bevel gear 34 meshes with the first bevel gear 33. The fourth bevel gear 36 is fixedly mounted on the output shaft of the rotating motor 32. The fourth bevel gear 36 meshes with the third bevel gear 35.

[0052] Reference Figure 2 The rotating motor 32 starts, driving the fourth bevel gear 36 to rotate. The rotation of the fourth bevel gear 36 drives the third bevel gear 35 to rotate. The rotation of the third bevel gear 35 drives the rotating rod 31 to rotate. The rotation of the rotating rod 31 drives the second bevel gear 34 to rotate. The rotation of the second bevel gear 34 drives the first bevel gear 33 to rotate. The rotation of the first bevel gear 33 drives the moving screw 26 to rotate. The rotation of the moving screw 26 drives the moving block 25 to move. The movement of the moving block 25 drives the stabilizing wheel 22 to move.

[0053] Reference Figure 2 The two sets of moving components 23 used to drive the two stabilizing wheels 22 share a single rotary motor 32. The fourth bevel gear 36 on the rotary motor 32 meshes with the third bevel gear 35 in both sets of moving components 23, and the threads of the moving lead screws 26 in the two sets of moving components 23 are reversed. Therefore, by controlling the rotary motor 32, the two stabilizing wheels 22 can be driven to move synchronously in opposite directions. This controls the contact area between the stabilizing wheels 22 and the fabric, thereby adjusting the movement speed on both sides of the fabric and completing the fabric correction work.

[0054] Reference Figure 1 and Figure 2 Two infrared detectors 37 are fixedly mounted on the frame 1. The two infrared detectors 37 are located on opposite sides of the fabric width. A controller 38 is fixedly mounted on the frame 1, and the controller 38 is electrically connected to both infrared detectors 37 and a rotating motor 32. The two infrared detectors 37 emit infrared radiation to detect fabric deviation on opposite sides. When an infrared detector 37 detects fabric misalignment, the controller 38 can control the rotating motor 32 to correct the fabric deviation.

[0055] Reference Figure 2 and Figure 3 The movable block 25 is equipped with an adjustment mechanism 4 for adjusting the distance between the two stabilizing wheels 22. The adjustment mechanism 4 includes an adjustment block 41, two fixed blocks 42, and two sets of drive assemblies 43. A horizontal moving groove 44 is formed on the upper surface of the adjustment block 41, and the bottom of the movable block 25 is slidably installed in the moving groove 44. The two fixed blocks 42 are horizontally slidably installed on opposite side walls of the moving groove 44, respectively, in a direction close to or away from the movable block 25. Both sets of drive assemblies 43 are disposed on the adjustment block 41, and the two fixed blocks 42 clamp the movable block 25 under the action of the two sets of drive assemblies 43.

[0056] Reference Figure 2 and Figure 3 The drive assembly 43 includes a drive spring 45 and a drive rod 46. A horizontal limiting groove 47 is formed on the inner wall of the moving groove 44, and a fixing block 42 is slidably mounted on the limiting groove 47. One end of the drive spring 45 is fixedly mounted on the inner bottom wall of the limiting groove 47. The other end of the drive spring 45 is connected to the fixing block 42. Under the action of the drive spring 45, the head of the fixing block 42 protrudes out of the limiting groove 47 and abuts against the outer wall of the moving block 25. The drive rod 46 is horizontally slidably mounted on the adjusting block 41, with one end connected to the fixing block 42 and the other end extending out of the adjusting block 41.

[0057] Reference Figure 3 Pulling the drive rod 46 causes the fixed block 42 to compress the drive spring 45, thus disengaging the fixed block 42 from the moving block 25, allowing the adjusting block 41 to move freely. Once the adjusting block 41 reaches the target position, releasing the drive rod 46 causes the fixed block 42 to press against the moving block 25 under the action of the drive spring 45, thereby fixing the position of the adjusting block 41.

[0058] The working principle of this application embodiment is as follows:

[0059] After the fabric woven by the jacquard machine is guided onto the fabric table 11, the stabilizing plate 21 is rotated, so that the stabilizing plate 21 drives the two stabilizing wheels 22 to press the fabric under the action of gravity. Thus, the stabilizing plate 21 and the stabilizing wheels 22 work together to flatten the fabric while ensuring that the fabric can continue to move and be guided out, reducing the probability of the fabric turning over or wrinkling under the influence of the external environment, so that the jacquard machine can maintain stable weaving work.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
