Description

Technical Field

[0001] The invention relates to the field of silk production equipment, in particular to a silk weaving rapier loom. Background Art

[0002] Currently, the rapier loom is the most widely used shuttleless loom. It utilizes a flexible or rigid rapier and a rapier head as the weft insertion mechanism. The rapier head grips the weft thread and transfers it through the shed for insertion. Its advantages include high speed, stability, and wide adaptability, making it the preferred machine for weaving various grades of clothing fabrics and other types of silk.

[0003] In the related art, the Chinese utility model patent with announcement number CN207227669U discloses a rapier loom, including a frame, on which a weft selector and a control mechanism for controlling the color selection of the weft selector are installed. The weft selector includes a plurality of weft selection fingers, and the weft selection fingers are provided with threading holes for yarn to pass through. The weft selector is provided with a transmission assembly connected to the weft selection fingers and a driving assembly that drives the weft selection fingers to select colors. The transmission assembly includes a rocker arm fixed to the weft selection finger at one end, a connecting rod rotatably connected to the other end of the rocker arm, and a long rod driven by the driving assembly to rotate, and the long rod is rotatably connected to the end of the connecting rod away from the rocker arm; a cloth winding mechanism and a driving machine that drives the cloth winding mechanism are provided on the frame, and the cloth winding mechanism includes a cloth winding roller and a cloth guide roller. The cloth guide roller is located above the cloth winding roller. One end of the output shaft of the driving machine is fixedly connected to the transmission wheel, and the middle part of the transmission wheel is fixed to one end of the cloth winding roller.

[0004] Regarding the above-mentioned related technologies, after the silk weaving is completed, the silk passes between the cloth guide roller and the cloth winding roller, and then is wound on the cloth winding roller. However, in the process of the cloth winding roller winding the silk, the silk sometimes wrinkles, causing creases on the silk wound on the cloth winding roller, thereby affecting the quality of the silk. Summary of the Invention

[0005] In order to reduce wrinkles in silk during the winding process and improve the quality of silk, the present application provides a silk weaving rapier loom.

[0006] The present application provides a silk weaving rapier loom adopting the following technical solutions:

[0007] A silk weaving rapier loom comprises a frame and a cloth winding roller for winding up silk, the frame being provided with a combing device, the combing device comprising two groups of combing members respectively arranged above and below the silk, the combing members comprising two roller brushes, both of which are arranged obliquely on the silk, the two roller brushes being close to each other at one end away from the cloth winding roller, the bristles of the roller brushes being in contact with the silk, and the roller brushes being rotatably arranged on the frame.

[0008] By adopting the above technical solution, the silk passes between the two groups of combing parts. When the roller brush rotates, the side of the roller brush close to the cloth winding roller rotates toward the silk. Therefore, when the silk passing through the combing parts becomes wrinkled, the silk can be combed and unfolded by the bristles of the roller brush, and then wound on the cloth winding roller, which reduces the wrinkles of the silk during the winding process and improves the quality of the silk.

[0009] Preferably, vertical strip holes are provided on the frame, a sliding block is provided on the side of the roller brush close to the frame, the roller brush is rotatably set on the sliding block, the sliding block is slidably set in the vertical strip holes, and the combing device includes an adjustment mechanism for adjusting the distance between the two sliding blocks in the vertical strip holes.

[0010] By adopting the above technical solution, the roller brushes above and below the silk are respectively rotatably set on the sliding blocks, and the sliding blocks are slidably set in the vertical strip holes. When the adjustment mechanism drives the two sliding blocks in the vertical strip holes to move closer to or away from each other, the two sliders in the vertical strip holes can adjust the distance between the roller brushes above and below the silk, so that the roller brushes can increase the distance between the roller brushes in the process of passing the newly produced silk through the combing device and guiding it to the cloth winding roller, making it easier to pass the newly produced silk through the combing device and guide it to the cloth winding roller.

[0011] Preferably, the adjustment mechanism includes a double-headed screw rotatably arranged in the vertical bar hole, the thread directions at both ends of the double-headed screw are opposite, the double-headed screw passes through the two sliding blocks in the vertical bar hole, the two sliding blocks are respectively located at both ends of the double-headed screw, the sliding blocks are threadedly connected to the double-headed screw, and an adjustment motor for driving the double-headed screw to rotate is fixed on the frame.

[0012] By adopting the above technical solution, the double-headed screw is rotatably arranged in the vertical bar hole, and the two sliding blocks in the vertical bar hole are respectively located at the two ends of the double-headed screw, and the sliding blocks are threadedly connected to the double-headed screw. Therefore, when the adjustment motor drives the double-headed screw to rotate, the two sliding blocks in the vertical bar hole can approach or move away from each other, so that the sliding blocks can drive the roller brushes above and below the silk to approach or move away from each other, so that the silk guiding process can have more space, which is convenient for guiding the newly produced silk.

[0013] Preferably, a horizontal slide groove is provided on the inner wall of the vertical bar hole, and a control mechanism is provided in the horizontal slide groove, and the control mechanism includes a control block slidably set in the horizontal slide groove, a fixed contact piece is embedded on the inner wall of the horizontal slide groove, and a dynamic contact piece for connecting with the fixed contact piece is embedded in the control block, a power supply is fixed on the frame, the fixed contact piece is electrically connected to one of the electrodes of the power supply, the other electrode of the power supply is electrically connected to one of the terminals of the adjusting motor, and the other terminal of the adjusting motor is electrically connected to the dynamic contact piece, and one end of the control block is provided with a first inclined surface for interfering with the sliding block.

[0014] By adopting the above technical solution, the control block is slidably arranged in the horizontal slide groove, the fixed contact piece is embedded in the inner wall of the horizontal slide groove, the movable contact piece is embedded in the control block, and the first inclined surface is arranged at one end of the control block. When the adjustment motor is started, the two sliding blocks in the vertical bar hole can approach each other. When the two sliding blocks are too close, the sliding block can push the control block into the horizontal slide groove through the interference with the first inclined surface, so that the movable contact piece is disengaged from the fixed contact piece, thereby automatically disconnecting the electrical circuit of the motor, reducing the possibility of the silk being damaged due to the excessive proximity of the roller brushes above and below the silk.

[0015] Preferably, a limiting groove is provided on the side wall of the transverse sliding groove, a limiting block is fixedly connected to the side surface of the control block, and the limiting block is slidably arranged in the limiting groove.

[0016] By adopting the above technical solution, a limit groove is opened on the inner wall of the horizontal slide groove, the limit block is fixed on the control block, and the limit block is slidably set in the limit groove, thereby preventing the control block from leaving the horizontal slide groove and improving the stability of the control mechanism structure.

[0017] Preferably, a return spring is provided in the transverse slide groove, one end of the return spring abuts against the side of the control block away from the sliding block, and the other end of the return spring abuts against the inner wall of the transverse slide groove away from the sliding block.

[0018] By adopting the above technical solution, one end of the return spring abuts against the side of the control block away from the sliding block, and the other end of the return spring abuts against the inner wall of the horizontal sliding groove away from the sliding block. When the double-headed screw is rotated in the opposite direction to make the two sliding blocks in the vertical bar hole move away from each other, the return spring can push the control block out of the horizontal sliding groove, so that the moving contact piece and the fixed contact piece contact again, so that after the two sliding blocks move away from each other, the electrical circuit of the regulating motor can be automatically connected.

[0019] Preferably, a driving motor is fixed on the sliding block, the output shaft of the driving motor passes through the sliding block, the roller brush is detachably connected to the output shaft of the driving motor, a slot is provided on the end surface of the output shaft, a snap-in hole is provided on the inner wall of the slot, an insert block for being inserted into the slot is fixedly connected to the end surface of the roller brush, a sliding groove is provided on the side surface of the insert block, a snap-in assembly is provided in the sliding groove, the snap-in assembly includes a snap-in block slidably set in the sliding groove, and one end of the snap-in block can be inserted into the snap-in hole.

[0020] By adopting the above technical solution, the insert block is inserted into the insert hole, and the clamping block is slidably set in the sliding groove. When the sliding groove coincides with the clamping hole, one end of the clamping block can be inserted into the clamping hole, thereby facilitating the disassembly and replacement of the roller brush and improving the replacement efficiency.

[0021] Preferably, a stop groove is provided on the inner wall of the sliding groove, a stop block is fixedly connected to the side surface of the clamping block, and the stop block is slidably disposed in the stop groove.

[0022] By adopting the above technical solution, the retaining groove is opened on the inner wall of the sliding groove, the retaining block is fixedly connected to the clamping block, and the retaining block is slidably arranged in the retaining groove, thereby preventing the clamping block from leaving the sliding groove, thereby making the structure of the clamping assembly more stable.

[0023] Preferably, a thrust spring is provided in the sliding groove, one end of the thrust spring abuts against the bottom wall of the sliding groove, and the other end of the thrust spring abuts against the blocking block.

[0024] By adopting the above technical solution, one end of the thrust spring abuts against the bottom wall of the sliding groove, and the other end of the thrust spring abuts against the clamping block. When the sliding groove coincides with the clamping hole, the clamping block can be inserted into the clamping hole at one end under the elastic force of the thrust spring, so that the clamping mechanism can more stably clamp the output shaft and the roller brush.

[0025] Preferably, the end of the clamping block away from the thrust spring is provided with two second inclined surfaces, and the two second inclined surfaces are respectively oriented toward a side close to and away from the driving motor.

[0026] By adopting the above technical solution, the two second inclined surfaces are respectively facing the side close to and away from the driving motor. In the process of inserting the plug into or out of the slot, the second inclined surfaces can help the block slide into the sliding groove under the resistance of the edge of the card hole and the outer edge of the slot, thereby facilitating the disassembly and installation of the roller brush, and facilitating the maintenance and replacement of the roller brush.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The silk passes between the two sets of combing parts. When the roller brush rotates, the side of the roller brush close to the cloth roller rotates toward the silk.

[0029] 2. The roller brushes above and below the silk are respectively rotatably arranged on the sliding blocks, and the sliding blocks are slidably arranged in the vertical strip holes. When the adjustment mechanism drives the two sliding blocks in the vertical strip holes to move closer to or away from each other, the two sliders in the vertical strip holes can adjust the distance between the roller brushes above and below the silk, so that the roller brushes can increase the distance between them when the newly produced silk passes through the combing device and is guided to the cloth winding roller, making it easier for the newly produced silk to pass through the combing device and be guided to the cloth winding roller;

[0030] 3. The control block is slidably arranged in the horizontal slide groove, the fixed contact piece is embedded in the inner wall of the horizontal slide groove, the movable contact piece is embedded in the control block, and the first inclined surface is arranged at one end of the control block. When the adjustment motor is started, the two sliding blocks in the vertical bar hole can approach each other. When the two sliding blocks are too close, the sliding block can push the control block into the horizontal slide groove through the interference with the first inclined surface, so that the movable contact piece is disengaged from the fixed contact piece, thereby automatically disconnecting the electrical circuit of the motor, reducing the possibility of the silk being damaged due to the roller brushes above and below the silk being too close.

The frame 1 is mounted on either side of the machine, with the cloth winding roller 2 and cloth guide roller 3 located at the same end of the frame 1. Both ends of the cloth winding roller 2 and cloth guide roller 3 are rotatably mounted on the frame 1, with the axes of the cloth winding roller 2 and cloth guide roller 3 positioned horizontally. The cloth winding roller 2 is located directly below the cloth guide roller 3. Silk 6 is woven into shape by the weaving device 5, then passes through the cloth guide roller 3 and is wound around the cloth winding roller 2.

[0039] Reference Figure 1 and Figure 2 As shown, the combing device 4 is located on the side of the cloth winding roller 2 near the weaving device 5. The combing device 4 includes a combing member 41, a sliding block 42, a drive motor 43, an adjustment mechanism 44, and a control mechanism 45. Vertical slots 11 are formed on the adjacent sides of the frame 1. Two sliding blocks 42 are provided in each vertical slot 11 for vertical sliding. The two sides of the sliding blocks 42 that are separated from each other respectively abut against the two side walls of the vertical slot 11.

[0040] Reference Figure 1 and Figure 2 As shown, two groups of combing members 41 are provided between the two frames 1, and the two groups of combing members 41 are respectively provided above and below the silk 6. The combing members 41 include two roller brushes 411, the axes of the two roller brushes 411 are located in the same horizontal plane, the axes of the two roller brushes 411 intersect and are symmetrically arranged, and the ends of the two roller brushes 411 away from the cloth roller 2 are close to each other.

[0041] Reference Figure 1 and Figure 3 As shown, the drive motor 43 corresponds to the sliding block 42 in a one-to-one manner. The drive motor 43 is fixedly mounted on the sliding block 42 and is located on the outside of the two side frames 1. The output shaft 431 of the motor passes through the sliding block 42 and is rotatably mounted on the sliding block 42. The roller brush 411 is detachably connected to the output shaft 431 of the drive motor 43.

[0042] Reference Figure 1 and Figure 3 As shown, a slot 432 is defined on the end face of the output shaft 431. The slot 432 has a rectangular cross-section and a latching hole 433 is defined on the inner wall of the slot 432. The latching hole 433 communicates with the outer circumference of the output shaft 431. An insert 4111 is welded and fixed to the end face of the roller brush 411. When the roller brush 411 is connected to the output shaft 431 of the drive motor 43, the insert 4111 is inserted into the slot 432.

[0043] Reference Figure 1 and Figure 3 As shown, a sliding groove 4112 is defined on the side of the insert block 4111, within which a clamping assembly 412 is disposed. The clamping assembly 412 comprises a clamping block 4121, a stopper 4122, and a thrust spring 4123. The clamping block 4121 slides within the sliding groove 4112. A stopper 4113 is defined on the inner wall of the sliding groove 4112, the length of which is parallel to the sliding direction of the clamping block 4121. The stopper 4122 is welded to the side of the clamping block 4121 and slides within the stopper 4113. The thrust spring 4123 is disposed within the sliding groove 4112, with one end of the thrust spring 4123 abutting against the bottom wall of the sliding groove 4112 and the other end of the thrust spring 4123 abutting against the clamping block 4121.

[0044] Reference Figure 1 and Figure 3 As shown, the end of the clamping block 4121 away from the thrust spring 4123 is provided with two second inclined surfaces 41211, which face toward and away from the drive motor 43, respectively. One end of the clamping block 4121 can be inserted into the engaging hole 433. During the insertion of the inserting block 4111 into the slot 432, the clamping block 4121 is first pushed into the sliding slot 4112. When the sliding hole is flush with the engaging hole 433, the elastic force of the thrust spring 4123 automatically inserts the end of the clamping block 4121 away from the thrust spring 4123 into the engaging hole 433, thereby facilitating the removal and installation of the roller brush 411, and facilitating maintenance and replacement of the roller brush 411.

[0045] Reference Figure 1As shown, the bristles of the roller brush 411 are in contact with the silk 6. When the driving motor 43 drives the roller brush 411 to rotate, the side of the roller brush 411 close to the cloth winding roller 2 rotates toward the silk 6, thereby combing out the wrinkles on the silk 6, reducing the wrinkles generated on the silk 6 during the winding process, and improving the quality of the silk 6.

[0046] Reference Figure 1 and Figure 2 As shown, two sets of adjustment mechanisms 44 are provided, one located on each side of the frame 1. The adjustment mechanisms 44 include a double-ended screw 441 and an adjustment motor 442. The double-ended screw 441 is vertically positioned within the vertical bar hole 11. The bottom wall of the vertical bar hole 11 defines a mounting slot 14. The bottom end of the double-ended screw 441 is inserted into the mounting slot 14, and the double-ended screw 441 rotates within the mounting slot 14.

[0047] Reference Figure 1 and Figure 2 As shown, the adjustment motor 442 is fixed to the top surface of the frame 1, and the rotating shaft of the adjustment motor 442 is coaxially welded to the top of the double-headed screw 441. The threads at both ends of the double-headed screw 441 are in opposite directions. The double-headed screw 441 passes through two sliding blocks 42 in the vertical bar hole 11. The two sliding blocks 42 are respectively located at the two ends of the double-headed screw 441, and the sliding blocks 42 are threadedly connected to the double-headed screw 441.

[0048] Reference Figure 1 and Figure 2 As shown, a transverse chute 12 is provided on the inner wall of the vertical strip hole 11, and the strip chute is located between the two transverse chute 12. There are two groups of control mechanisms 45, and the two groups of control mechanisms 45 are respectively arranged in the transverse chute 12 on the inner wall of the two vertical strip holes 11.

[0049] Reference Figure 2 and Figure 4 As shown, the control mechanism 45 includes a control block 451, a fixed contact piece 452, a movable contact piece 453, a power supply 454, a limit block 455, and a return spring 456. The control block 451 is horizontally slidably disposed within the transverse slide groove 12, the fixed contact piece 452 is embedded in the top wall of the transverse slide groove 12, and the movable contact piece 453 is embedded in the top surface of the control block 451.

[0050] Reference Figure 2 and Figure 4As shown, a limit slot 13 is defined on the bottom wall of the transverse chute 12, the length of which is parallel to that of the transverse chute 12. A limit block 455 is welded to the bottom surface of the control block 451 and slides within the limit slot 13. A return spring 456 is disposed within the transverse chute 12, one end of which abuts the side of the control block 451 away from the sliding block 42, while the other end of the return spring 456 abuts the inner wall of the transverse chute 12 away from the sliding block 42. A first inclined surface 4511 is provided on the end of the control block 451 away from the return spring 456, with the first inclined surface 4511 facing upward.

[0051] Reference Figure 2 and Figure 4 As shown, the power supply 454 is fixed to the frame 1, the fixed contact piece 452 is electrically connected to one of the electrodes of the power supply 454, the other electrode of the power supply 454 is electrically connected to one of the terminals of the adjustment motor 442, and the other terminal of the adjustment motor 442 is electrically connected to the movable contact piece 453. When the two sliding blocks 42 are too close to each other, the sliding blocks 42 can push the control block 451 into the horizontal slot 12 through the interference effect with the first inclined surface 4511, so that the movable contact piece 453 is disengaged from the fixed contact piece 452, thereby automatically disconnecting the electrical circuit of the motor, reducing the possibility of the silk 6 being damaged due to the excessive proximity of the roller brushes 411 above and below.

[0052] Reference Figure 2 and Figure 4 As shown, an adjusting nut 443 is welded and fixed to the middle part of the double-headed screw 441. When the moving contact piece 453 is disengaged from the fixed contact piece 452, the two sliding holes in the vertical bar hole 11 can be moved away from each other by manually rotating the adjusting nut 443, so that the moving contact piece 453 and the fixed contact piece 452 can be re-contacted under the elastic force of the reset spring 456 on the control block 451.

[0053] The implementation principle of a silk weaving rapier loom in an embodiment of the present application is as follows: the silk 6 passes between two groups of combing parts 41. When the driving motor 43 drives the roller brush 411 to rotate, the side of the roller brush 411 close to the cloth winding roller 2 rotates toward the direction close to the silk 6. Therefore, when the silk 6 passing through the combing parts 41 is wrinkled, the silk 6 can be combed and unfolded by the bristles of the roller brush 411, and then wound on the cloth winding roller 2, thereby reducing the wrinkles of the silk 6 during the winding process and improving the quality of the silk 6.

[0054] When the two sliding blocks 42 are too close to each other, the sliding block 42 can push the control block 451 into the horizontal slide groove 12 through the interference with the first inclined surface 4511, so that the moving contact piece 453 is disengaged from the fixed contact piece 452, thereby automatically disconnecting the electrical circuit of the motor, reducing the possibility of the silk 6 being damaged due to the roller brushes 411 above and below the silk 6 being too close.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
