Description

Technical Field

[0001] This invention relates to the field of leather cord flower weaving technology, specifically a leather cord flower weaving method and weaving device. Background Technology

[0002] As is widely known, weaving is one of the oldest handicrafts, and leather rope is an indispensable material for weaving. Leather rope is not only strong and durable but also looks very classy. Because leather rope is associated with peace and good fortune, leather rope flowers are widely loved. However, the production of leather rope products is limited, so leather rope flower weaving equipment is needed to assist in the weaving process. Existing weaving devices weave and roll up the leather rope before cutting it, so that the rolled-up leather rope flowers are cut into pieces of the same length.

[0003] For example, the invention patent with publication number [number missing], publication date June 28, 2019, and titled "Combined Rope Weaving Method and Weaving Device," provides a combined rope weaving method and device, relating to the field of rope weaving technology, to solve the problems of low production efficiency and easy breakage of combined ropes. The combined rope weaving method includes: starting the weaving device, with the spindle moving along a first trajectory to weave a round rope; after the length of the woven round rope reaches a first set value, the control system controls the conversion mechanism to move, so that the movement trajectory of the spindle is changed to a second trajectory, and the spindle moves along the second trajectory to weave a flat rope. The combined rope weaving method is used in a weaving device to produce combined ropes. The rope woven using this combined rope weaving method is a combined rope including round rope segments and flat rope segments, and the round rope segments and flat rope segments can be continuously completed by one set of weaving devices without changing equipment or requiring a step of connecting the round rope and flat rope. It is convenient to operate, has high production efficiency, strong connection strength, and is not easily broken.

[0004] In the existing technology, the existing weaving device can only weave the leather rope and then roll it up. Since the leather rope is not knotted during weaving, the ends of the leather rope will come apart when it is cut. At this time, the separated ends need to be tied manually. Summary of the Invention

[0005] The purpose of this invention is to provide a leather cord flower weaving method and weaving device to solve the above-mentioned problems in the prior art.

A first gear is installed at the other end of the connecting shaft located on the outside of the plate.

[0016] As described above, a traction wheel is provided at the end of the top plate, and two auxiliary blocks are symmetrically installed on the top plate about the cross plate. The traction wheel and auxiliary blocks are used for the traction operation of the leather rope.

[0017] The aforementioned weaving unit includes a weaving disc with a weaving groove. The weaving groove is an annular wave groove, i.e., a wave groove connected end to end. A first rotating rod is mounted at the center of the weaving disc via a rotatable engagement. The bottom end of the first rotating rod is connected to the output end of a first motor, which is fixedly mounted at the bottom of the weaving disc.

Multiple leather cords are woven together to form a leather rope.

[0018] The aforementioned braiding unit further includes a fourth rotating rod. The fourth rotating rod is mounted on the edge of the second turntable in a rotatable engagement manner. A through groove is provided in the middle of the fourth rotating rod. A flat block is fitted on the outer wall of the fourth rotating rod, and a thread-passing hole is provided on the flat block.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] In various embodiments of the present invention, the raw material before the weaving unit performs the weaving operation is leather thread. The finished product after the weaving unit weaves multiple leather threads is called a leather rope. The leather rope after being cut and decorated is called a leather rope flower. The leather rope flower weaving method is essentially the leather rope weaving method plus corresponding hand decoration methods.

[0039] like Figures 1 to 13 As shown in the figure, an embodiment of the present invention provides a leather rope flower weaving method, which is based on a leather rope flower weaving device, the leather rope flower weaving device including a weaving unit 1 and a winding unit 2, and the leather rope flower weaving method includes the following steps:

[0040] The leather rope is woven using weaving unit 1;

[0041] The leather rope is squeezed and tied by C-shaped pieces 4, so that two C-shaped pieces 4 are fitted on the outer wall of the leather rope at equal lengths;

[0042] The winding unit 2 performs the winding operation on the leather rope woven by the braiding unit 1.

[0043] Specifically, the leather rope is woven by the weaving unit 1, and then the woven leather rope is wound up by the winding unit 2. After the leather rope is woven, it is easy for it to unravel. The core of this invention is that after the leather rope is woven by the weaving unit 1 and before the leather rope is wound up by the winding unit 2, the leather rope is squeezed and tied by the C-shaped piece 4. This ensures that two C-shaped pieces 4 are fitted on the outer wall of the leather rope at equal intervals, preventing the leather rope from unraveling and improving the weaving efficiency of the leather rope.

[0044] Furthermore, after the rope is wound up by the winding unit 2:

[0045] The position between two adjacent C-shaped pieces 4 at the same compression and tying point on the leather rope is cut to make multiple leather ropes of the same length. Specifically, the position between two adjacent C-shaped pieces 4 at the same compression and tying point on the leather rope (that is, the part between two C-shaped pieces 4 with a small gap) can be cut using existing cutting equipment or manually with scissors to obtain multiple leather ropes of the same length. Because the leather rope is compressed and tied by the C-shaped pieces 4, the leather rope will not unravel after cutting. However, in the prior art, the leather rope often unravels during cutting because it is not tied. After the leather rope unravels, it needs to be re-woven manually, which reduces the cutting efficiency of the leather rope.

[0046] Another embodiment of the present invention provides a leather rope weaving device, including a weaving unit 1, a winding unit 2, and a binding unit 3 disposed between the winding unit 2 and the weaving unit 1. The binding unit 3 is used to press C-shaped pieces 4 onto the outer wall of the leather rope, so that the C-shaped pieces 4 perform a binding operation on the leather rope. Specifically, the leather rope is woven by the weaving unit 1, and the C-shaped pieces 4 are pressed tightly against the outer wall of the leather rope by the binding unit 3, so that there are two binding openings of C-shaped pieces 4 at the same length position on the outer wall of the leather rope, so that the leather rope will not unravel during subsequent cutting operations. Then, the winding unit 2 performs a winding operation on the leather rope with the binding completed, to obtain a wound leather rope with the binding completed.

[0047] Furthermore, the tying unit 3 includes a top plate 31, with two flat plates 32 mounted in the middle of the top plate 31. A positioning shaft 33 is rotatably connected between the two flat plates 32, meaning that each end of the positioning shaft 33 is rotatably connected to a flat plate 32. A cross plate 34 is mounted on the positioning shaft 33, and a bidirectional cylinder 35 and a limiting strip 36 are mounted at each of the four ends of the cross plate 34. An L-shaped clamping plate 37 is mounted at each of the two ends of each bidirectional cylinder 35, and the L-shaped clamping plate 37 is slidably mounted on the limiting strip 36 through a through hole. An arc-shaped panel 38 is mounted on the end of the L-shaped clamping plate 37 facing away from the bidirectional cylinder 35. Two L-shaped clamping plates 37 connected to the same bidirectional cylinder 35 have two arc panels 38 arranged opposite each other. Specifically, (1) when two arc panels 38 move to their highest point as the cross plate 34 rotates, two C-shaped pieces 4 are placed between the arc panels 38 by a robot or manually, so that the opening position of the C-shaped pieces 4 coincides with the top of the two arc panels 38 (that is, when the C-shaped pieces 4 are placed between the arc panels 38, the opening position of the C-shaped pieces 4 faces the top of the cross plate 34 and the opening is upward). The bidirectional cylinder 35 located at the top of the cross plate 34 drives the L-shaped clamping plates 37 to slide towards each other on the limiting strip 36. This causes the L-shaped clamping plate 37 to move the arc panel 38 towards one end, so that the arc panel 38 clamps the C-shaped piece 4. When the arc panel 38 has finished clamping the C-shaped piece 4, the bidirectional cylinder 35 stops moving and drives the positioning shaft 33 to make the cross plate 34 rotate intermittently at 90 degrees. (2) When the woven leather rope passes between the two arc panels 38 at the bottom of the cross plate 34 (that is, when the arc panel 38 clamping the C-shaped piece 4 is pressed against the outer wall of the leather rope, the leather rope is deformed downward by being pressed and then reset to enter the opening of the C-shaped piece to realize the wrapping operation of the C-shaped piece 4 on the outer wall of the leather rope), the bidirectional cylinder 35 continues to move. The L-shaped clamp 37 slides towards one end on the limiting strip 36, causing the arc panel 38 to move towards the other end. This compression forces the C-shaped piece 4 to deform, allowing the arc panel 38 to tie the rope with the C-shaped piece 4, improving the tying quality of the rope. After the tying operation is completed, the bidirectional cylinder 35 drives the L-shaped clamp 37 to slide away from the other end on the limiting strip 36, causing the arc panel 38 to detach from the C-shaped piece 4. Thus, when the cross plate 34 rotates, the arc panel 38, which is now detached from the rope, will not affect the rope during rotation.

[0048] Furthermore, an arc groove 39 is formed in the middle of the arc-shaped inner side of each of the eight arc panels 38. An arc plate 310 is slidably installed in each arc groove 39. Both ends of the eight arc plates 310 extend out of their corresponding arc grooves 39 and are provided with reset plates 311. A first baffle 312 is provided on the side wall of each of the four limiting strips 36 near the arc plate 310 and between the two corresponding reset plates 311. Two second baffles 313 are symmetrically arranged on the side wall of the arc plate 310, located outside the reset plate 311. The first baffle 312 and the second baffle 313 are used in conjunction with the reset plate 311. Specifically, (1) when the bidirectional cylinder 35 drives the arc plate 38 to move towards one end through the L-shaped clamp 37, the arc plate 38 drives the arc plate 310 to slide towards one end. The arc plate 310 drives the reset plate 311 located on its top side to press against the outer wall of the first baffle 312. Plate 312 drives the arc-shaped plate 310 to slide within the arc groove 39 via the reset plate 311, causing the reset plate 311 on the bottom side of the arc-shaped plate 310 to slide in an arc shape towards one end (since the arc-shaped plate 310 is slidably mounted in the arc groove 39, when the reset plate 311 on the top side of the arc-shaped plate 310 abuts, the reset plate 311 on the bottom side of the arc-shaped plate 310 slides in an arc shape, causing the reset plate 311 on the bottom side of the arc-shaped plate 310 to push the opening of the C-shaped piece 4), thus causing the bottom side of the arc-shaped plate 310 to... (1) The reset plate 311 performs a squeezing and sealing operation on the C-shaped piece 4; (2) When the bidirectional cylinder 35 drives the arc panel 38 to move away from each other through the L-shaped clamp 37, after the arc panel 38 is separated from the C-shaped piece 4, the reset plate 311 at the top of the arc panel 38 comes into contact with the second baffle 313. Due to the limiting operation of the second baffle 313, the reset plate 311 at the top of the arc plate 310 drives the reset plate 311 at the bottom of the arc plate 310 to slide away from each other, so that the arc plate 310 slides to the open position to avoid the leather rope.

[0049] Furthermore, the outer wall of the arc plate 310 and the arc groove 39 are abutted by the elastic element 314. Specifically, (1) when the bidirectional cylinder 35 drives the arc plate 38 to move towards one end through the L-shaped clamp 37, and the arc plate 310 slides in an arc shape in the arc groove 39, the elastic element 314 is in a compressed state; (2) when the bidirectional cylinder 35 drives the arc plate 38 to move away from one end through the L-shaped clamp 37, before the reset plate 311 at the top of the arc plate 38 abuts against the second baffle 313, the arc plate 310 slides to the open position in the arc groove 39 through the reset of the elastic element 314, which can effectively prevent the arc plate 310 from being unable to reset in case the second baffle 313 deforms or even breaks.

[0050] Furthermore, a grooved wheel 315 is also provided on the positioning shaft 33. A connecting shaft 316 is rotatably mounted on the flat plate 32 on the top plate 31 near the grooved wheel 315. A turning wheel 317 is installed at one end of the connecting shaft 316 located between the flat plates 32, and the turning wheel 317 and the grooved wheel 315 cooperate with each other. A first gear 318 is installed at the other end of the connecting shaft 316 located on the outside of the flat plate 32. Specifically, since C-shaped pieces 4 need to be added between the arc panels 38 at the top of the cross plate 34, and the C-shaped pieces 4 between the arc panels 38 at the bottom of the cross plate 34 need to be used to squeeze and tie the leather rope, Since the positioning shaft 33 needs to pause after rotating 90 degrees before resuming rotation, the optimal mechanism is the rotating grooved wheel 315. Therefore, the grooved wheel 315 is installed on the positioning shaft 33, and the transmission operation is carried out through the actuating wheel 317. When the cross plate 34 needs to rotate 90 degrees, the first gear 318 is driven to drive the actuating wheel 317 to rotate one revolution through the connecting shaft 316. The actuating wheel 317 drives the grooved wheel 315 to rotate 90 degrees and performs a positioning operation. The grooved wheel 315 drives the cross plate 34 to rotate 90 degrees through the positioning shaft 33. In this way, the requirement for the cross plate 34 to stop after rotating 90 degrees can be solved.

[0051] Furthermore, a traction wheel 319 is provided at the end of the top plate 31, and two auxiliary blocks 320 are symmetrically installed on the top plate 31 about the cross plate 34. The traction wheel 319 and the auxiliary blocks 320 are used for the traction operation of the leather rope. Specifically, after the weaving unit 1 completes the weaving operation of the leather rope, the leather rope passes through the traction wheel 319 and the auxiliary blocks 320, which improves the traction quality of the leather rope by the traction wheel 319 and the auxiliary blocks 320.

[0052] Furthermore, the weaving unit 1 includes a weaving disc 11, on which a weaving groove 12 is formed. The weaving groove 12 is an annular wave groove, that is, a wave groove with its ends connected. A first rotating rod 13 is mounted at the center of the weaving disc 11 by means of rotational engagement. The bottom end of the first rotating rod 13 is connected to the output end of a first motor 14. The first motor 14 is fixedly mounted at the bottom end of the weaving disc 11. A first turntable 15 is mounted at the top end of the first rotating rod 13. Multiple square rods 16 are evenly mounted on the outer wall of the first turntable 15 along its circumferential direction. A through groove 17 is formed on the square rod 16. A block 18 is mounted in the through groove 17 by means of sliding engagement. A second rotating rod 19 is mounted in the block 18 by means of rotational engagement. The bottom end of the second rotating rod 19 is mounted in the weaving groove 12 by means of sliding engagement. A second turntable 110 is mounted at the top end of the second rotating rod 19. The center of the second turntable 110 is set at... There is a third rotating rod 111, which is used to insert a single coiled leather cord to form a leather cord spool. Multiple leather cords are braided to form a leather rope. Specifically, when the leather rope needs to be braided, the worker puts the leather cord spool on the outer wall of the third rotating rod 111, starts the first motor 14 to drive the first rotating rod 13 to rotate, the first rotating rod 13 drives the first turntable 15 to rotate, the first turntable 15 drives the square rod 16 to rotate, the square rod 16 drives the square block 18 to rotate, and the square block 18 drives the second rotating rod 19 to slide along the trajectory of the braiding groove 12. During the process of the second rotating rod 19 sliding along the trajectory of the braiding groove 12, the second rotating rod 19 drives the square block 18 to slide along the trajectory of the through groove 17, so that the second rotating rod 19 and the second turntable 110 drive the third rotating rod 111 to move. Since the braiding groove 12 is an annular wave groove, the second rotating rod 19 and the second turntable 110 drive the leather cord spool to carry out the braiding operation through the third rotating rod 111. Multiple third rotating rods 111 achieve the weaving of leather ropes by rotating within an annular wave groove and by arranging them with different radial dimensions. This is existing technology and will not be described in detail.

[0053] Furthermore, the braiding unit 1 also includes a fourth rotating rod 112. The fourth rotating rod 112 is mounted on the edge of the second turntable 110 in a rotatable manner. A through groove 113 is provided in the middle of the fourth rotating rod 112. A flat block 114 is fitted on the outer wall of the fourth rotating rod 112. A wire hole is provided on the flat block 114. A locking rod 115 is mounted on the top of the fourth rotating rod 112 in a rotatable manner. A groove 116 is provided on the top of the third rotating rod 111. A lifting rod 120 is installed in the groove 116 in a sliding manner. The bottom end of the lifting rod 120 and the inner wall of the groove 116 are connected by a return spring 117. The ends of the locking rods 115 of the lifting rod 120 are interlocked with each other. Specifically, (1) after the yarn tube is fitted on the outer wall of the third rotating rod 111, the lifting rod is manually pressed. The rod 120 is inserted into the groove 116. At this time, the return spring 117 is in a compressed state. The locking rod 115 is manually rotated so that the end of the locking rod 115 moves to the relative position with the lifting rod 120. The pressing of the lifting rod 120 is manually released. Under the rebound action of the return spring 117, the lifting rod 120 and the locking rod 115 are inserted into each other, so that the locking rod 115 performs a limiting operation on the yarn drum. (2) When the yarn drum is rotating and weaving, due to the winding characteristics of the yarn drum (that is, the winding of the yarn drum is from one side of its drum to the other side), when the yarn drum is unwinding, the yarn always passes through the wire hole and drives the flat block 114 to slide along the trajectory of the fourth rotating rod 112, so that the unwinding of the yarn through the flat block 114 is more stable and the unwinding quality of the yarn is improved.

[0054] Furthermore, a braiding sleeve 118 is provided at the bottom end of the top plate 31 near the braiding disc 11, and a braiding insert 119 is provided at the center of the top of the braiding disc 11. The braiding insert 119 and the braiding sleeve 118 cooperate with each other. Specifically, when the yarn spool is unwinding and braiding, the braided yarn passes through the braiding sleeve 118, and the joint position of each yarn abuts against the top of the braiding insert 119. When the yarn is rotating and braiding, the braiding insert 119 rotates synchronously with the braiding disc 11, so that the braiding insert 119 abuts against the yarn and the braiding sleeve 118 loops the yarn and braids it, preventing the yarn from unraveling after braiding.

[0055] Furthermore, the winding unit 2 includes a square plate 21, and two square plates 21 are symmetrically mounted on the top plate 31. A second motor 22 is mounted on the outer wall of the square plate 21 on the same side as the first gear 318 on the top plate 31. A second gear 23 is mounted on the output end of the second motor 22, and a locking rod 24 is mounted on the second gear 23. A positioning circular plate 25 is mounted on the square plate 21 on the same side as the cross plate 34 on the top plate 31 in a rotatable engagement manner. A T-shaped rod 26 is mounted on the center of the positioning circular plate 25 in a sliding engagement manner. The T-shaped rod 26 and the positioning circular plate 25 are positioned and connected by a threaded rod 27. The locking rod 24 and the T-shaped rod 26 are connected by an insertable square plate. The winding roller 28 is connected to the winding roller 28, which is used for winding the leather rope. Specifically, (1) one end of the winding roller 28 is inserted into the clamping rod 24, and the operator continues to insert the T-shaped rod 26 into the other end of the winding roller 28. The operator positions the T-shaped rod 26 on the positioning plate 25 through the threaded rod 27 to install the winding roller 28; (2) after the winding roller 28 has finished winding the leather rope with the knot, the operator removes the threaded rod 27 from the positioning plate 25, pulls out the T-shaped rod 26 from the winding roller 28 and the positioning plate 25, takes out the winding roller 28 that has been wound, and then replaces the winding roller 28. The replacement is relatively convenient.

[0056] Furthermore, an auxiliary support chain 5 is also provided on the top plate 31. The auxiliary support chain 5 includes a rectangular frame 51. The rectangular frame 51 is mounted on the top plate 31 via a support plate. A drive roller 52 is mounted inside the rectangular frame 51 via a driven shaft in a rotatable engagement. A propulsion groove 53 is formed on the outer wall of the drive roller 52 along its circumferential direction. The propulsion groove 53 is a wave-shaped annular groove formed by four connected oblique arc surfaces, that is, a wave-shaped groove with its ends connected to form an annular shape. A U-shaped frame 54 is mounted on the inner walls of both sides of the rectangular frame 51 in a sliding engagement manner. Two sliding supports are symmetrically mounted on opposite surfaces of the U-shaped frame 54. The movable round rod 55 and the two sliding round rods 55 are installed in the feed groove 53 in a rotatable engagement manner. The top of the U-shaped frame 54 is equipped with a traction block 56. The driven shaft and the end on the same side as the second gear 23 pass through the rectangular frame 51 and are equipped with a third gear 57. The first gear 318, the second gear 23 and the third gear 57 are connected by an internal toothed belt 58. Specifically, after the braiding unit 1 finishes braiding the leather rope, the worker pulls the end of the leather rope through the traction wheel 319, the auxiliary block 320 and the traction block 56 and connects it to the take-up roller 28. The take-up roller 28 then takes up the tied leather rope. During operation, the second motor 22 is started, driving the second gear 23 to rotate. The second gear 23 drives the take-up roller 28 to wind the rope via the latch 24. Simultaneously, the second gear 23 drives the first gear 318 and the third gear 57 to rotate via the internal gear belt 58. While the first gear 318 is rotating, it drives the actuating wheel 317 to rotate via the connecting shaft 316. The actuating wheel 317 drives the grooved wheel 315 to rotate 90 degrees. This allows the take-up roller 28 to wind the rope while the C-shaped plate 4 squeezes and ties the rope, thus achieving both the winding and tying of the rope. The components work together. When the third gear 57 drives the driven shaft to rotate, the driven shaft drives the driving roller 52 to rotate. During the rotation of the driving roller 52, the sliding rod 55 slides along the trajectory of the feed groove 53. Since the feed groove 53 is a wavy annular groove, the sliding rod 55 drives the U-shaped frame 54 to slide along the trajectory of the rectangular frame 51. This causes the U-shaped frame 54 to drive the traction block 56 to perform linear reciprocating motion. The traction block 56 then drives the rope to perform linear reciprocating motion along the axis of the winding roller 28, making the winding of the rope more stable.
