Description

Technical Field

[0001] This invention belongs to the field of garment production technology and relates to an automated device for knotting Chinese knot buttons. Background Technology

[0002] A Chinese knot button, also known as a frog button, is a type of button used in traditional clothing to fasten or decorate garments, typically found on qipaos and Tang suits. A Chinese knot button consists of a strap and a knot. The strap and knot are sewn onto opposite sides of the garment's front. The strap is formed by folding a rope in half, and the knot is formed by weaving and tightening the rope into a ball shape. The knot is then fastened inside the strap to connect the two sides of the garment. The knotting process involves many manual steps, resulting in long production times, low efficiency, and high labor costs. Furthermore, the varying degrees of tightening during manual weaving lead to inconsistent knot sizes, affecting uniformity and aesthetics. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an automated knotting device capable of automatically knotting a disc knot.

[0004] The objective of this invention can be achieved through the following technical solution: An automated knotting device for a disc buckle includes a base plate and a clamping mechanism, a first winding mechanism, a second winding mechanism, a positioning seat, a rope pulling mechanism, a material cutting mechanism, and a transmission motor mounted on the base plate. The first winding mechanism and the second winding mechanism are respectively located on both sides of the front of the positioning seat and are arranged opposite to each other. The clamping mechanism is located directly behind the positioning seat. The first winding mechanism includes a first winding moving cylinder and a first winding block. The second winding mechanism includes a second winding moving cylinder and a second winding block. The rope pulling mechanism is equipped with a rope pulling cylinder and a rope pulling rod. Located on the side of the second winding block, the end of the rope passes through the positioning seat and is sequentially wound around the second winding block, the pull rope rod, and the first winding block. After winding is completed, the first winding moving cylinder drives the first winding block to move down and detach from the rope. The pull rope cylinder drives the pull rope rod to move backward to tighten the rope. The second winding moving cylinder drives the second winding block to move down and detach from the rope. The clamping mechanism clamps the rope. The transmission motor drives the clamping mechanism and the rope to move away from the positioning seat to tighten the rope, thus completing the knotting and tightening. The cutting mechanism includes pneumatic scissors, which cut the knot.

[0005] The aforementioned automated knotting equipment for making disc buckles also includes a feeding mechanism mounted on a base plate. The feeding mechanism is located directly behind the clamping mechanism. The feeding mechanism includes a first roller, a second roller, a feeding motor, and a feeding seat. The feeding seat is fixed to the base plate. The two ends of the first roller and the second roller are hinged to the two side plates of the feeding seat. The feeding motor is fixed to the base plate. The feeding motor drives the second roller to rotate via a synchronous belt. The first roller is located above the second roller. The rope is located between the first roller and the second roller and is in contact with both the first roller and the second roller. When the second roller rotates, it drives the rope to move closer to the positioning seat, while simultaneously driving the first roller to rotate synchronously.

[0006] In the aforementioned automated knotting equipment for making disc buckles, the first winding mechanism further includes a winding fixing seat and a first limiting plate. The winding fixing seat is fixed on the base plate, and the bottom of the first limiting plate is mounted on the winding fixing seat. A limiting opening is formed on the first limiting plate, and the first winding block is located within the limiting opening. A winding moving block is slidably disposed on the winding fixing seat. A first winding moving cylinder is fixed on the base plate and connected to the winding moving block. The first winding block is located above the winding moving block. The first winding moving cylinder drives the winding moving block and the first winding block to move up and down. During the downward movement of the first winding block, the rope on the first winding block contacts the first limiting plate and is limited by the first limiting plate.

[0007] In the aforementioned automated knotting equipment for disc buckles, the second winding mechanism further includes a second limiting plate. The mounting structure of the second winding block is the same as that of the first winding block, and the mounting structure of the second limiting plate is the same as that of the first limiting plate.

[0008] The aforementioned automated knotting equipment for making disc buckles also includes a pressing mechanism mounted on a base plate. The pressing mechanism, the rope pulling mechanism, and the cutting mechanism are arranged sequentially from front to back and are all located on the side of the second winding mechanism. The pressing mechanism includes a pressing base, a pressing cylinder, and a pressing block. The bottom of the pressing base is fixed to the base plate. The pressing cylinder is mounted on the pressing base. The pressing block is mounted on the end of the piston rod of the pressing cylinder. The pressing block has a pressing inclined surface. Before the rope pulling rod moves to tighten the rope, the pressing cylinder drives the pressing block to move forward. The pressing inclined surface presses down on the rope wound on the second winding block. After the rope pulling rod finishes pulling the rope, the pressing cylinder drives the pressing block to move backward and disengage from the rope on the second winding mechanism.

[0009] In the aforementioned automated knotting equipment for making disc buckles, the positioning seat has a positioning groove, and rope winding grooves are connected to the two side walls of the positioning groove. The rope winding grooves are located on the side of the positioning seat near the first winding mechanism and the second winding mechanism, and the rope passes through the positioning groove.

[0010] In the aforementioned automated knotting equipment for Chinese knots, the rope-pulling mechanism further includes a rope-pulling base, a vertical moving cylinder, and a rope-pulling limit block. The rope-pulling base is fixed to the base plate, and a rope-pulling block is slidably mounted on the rope-pulling base. The vertical moving cylinder is mounted on the base plate, and its piston rod is connected to the rope-pulling block, driving the rope-pulling block to move up and down. The rope-pulling cylinder is mounted on the rope-pulling block, and a rope-pulling connecting block is provided at the end of the piston rod. The bottom of the rope-pulling rod is inserted into the rope-pulling connecting block, and the rope-pulling cylinder drives the rope-pulling mechanism. The connecting block and the pull rope rod move. The top of the pull rope rod is also provided with a limiting protrusion. The bottom of the pull rope limiting block is connected to the base plate. The pull rope limiting block is located on the path of the pull rope cylinder driving the pull rope rod to move backward and pull the rope. The pull rope limiting block is provided with a moving notch. The width of the moving notch is greater than the width of the limiting protrusion. During the movement of the pull rope rod, it enters the moving notch. The up and down moving cylinder drives the pull rope moving block, the pull rope cylinder, and the pull rope rod to move down synchronously. The rope wrapped on the pull rope rod contacts the pull rope limiting block and disengages from the pull rope rod and the limiting protrusion.

[0011] In the aforementioned automated knotting equipment for disc buckles, the cutting mechanism further includes a push cylinder, a movable slide block, and a second slide rail. Two second slide rails are provided and fixed to the base plate. The bottom of the movable slide block is slidably mounted on the two second slide rails, allowing it to slide relative to the base plate. The push cylinder is mounted on the movable slide block, and a cutting moving block is slidably mounted on the movable slide block. The push cylinder drives the cutting moving block to move, and pneumatic scissors are mounted on the cutting moving block. The push cylinder drives both the cutting moving block and the pneumatic scissors to move.

[0012] In the aforementioned automated knotting equipment for making disc buckles, the clamping mechanism includes a clamping cylinder and two opposing clamping jaws. The clamping cylinder drives the two clamping jaws to move relative to each other to clamp the rope. A transmission mechanism is also provided on the base plate. The transmission mechanism includes a transmission motor and a transmission synchronous belt. The transmission motor drives the transmission synchronous belt to move. A transmission block is fixed to the bottom of the clamping cylinder. A clamping plate is installed on the transmission block. The transmission synchronous belt is clamped by the clamping plate and the transmission block, so that the transmission synchronous belt drives the transmission block, the clamping cylinder, and the clamping jaws to move synchronously. A first slide rail is also fixed on the base plate, and the bottom of the transmission block is slidably disposed on the first slide rail.

[0013] Compared with existing technologies, this automated knotting equipment for disc knots facilitates rope winding by setting up two molds: a first winding block and a second winding block. Simultaneously, the coordinated operation of a clamping mechanism, a first winding mechanism, a second winding mechanism, a positioning seat, a pressing mechanism, a rope pulling mechanism, and a cutting mechanism enables automatic tightening, automatic knotting, and cutting. This ensures uniform tightening force, guaranteeing the uniformity and aesthetics of the knots, achieving semi-automatic production, significantly shortening production time, and improving production efficiency. After the feeding motor drives the second roller to rotate a set number of times, the feeding motor stops, stopping the feeding and ensuring that the rope advances the same length each time, guaranteeing the same length of rope used for knotting each time, ensuring uniformity after knot production, and reducing rope waste.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-4 As shown, the automated knotting equipment for this disc knot includes a base plate 1 and a feeding mechanism 2, a clamping mechanism 3, a first winding mechanism 4, a second winding mechanism 5, a positioning seat 6, a pressing mechanism 7, a rope pulling mechanism 8, and a cutting mechanism 9 mounted on the base plate 1. The first winding mechanism 4 and the second winding mechanism 5 are located on opposite sides of the front of the positioning seat 6. The pressing mechanism 7, the rope pulling mechanism 8, and the cutting mechanism 9 are arranged sequentially from front to back and are all located on the side of the second winding mechanism 5. The feeding mechanism 2, the clamping mechanism 3, and the positioning seat 6 are arranged in a straight line, with the clamping mechanism 3 located directly behind the positioning seat 6 and the feeding mechanism 2 located directly behind the clamping mechanism 3.

[0021] In the above technical solution: several side plates 12 are installed on the base plate 1, a top plate 13 is installed on the top of the side plates 12, and a controller 14 is installed on the top plate 13. The side plates 12 and the top plate 13 are used to protect the structure on the base plate 1, and the controller 14 includes a control screen for controlling the operation and stop of each mechanism.

[0022] In the above technical solution: the feeding mechanism 2 includes a first roller 21, a second roller 22, a feeding motor 23, and a feeding seat 24. The feeding seat 24 is fixed on the base plate 1, and the two ends of the first roller 21 and the second roller 22 are hinged to the side plates of the feeding seat 24. The feeding motor 23 is fixed on the base plate 1, and the feeding motor 23 drives the second roller 22 to rotate via a synchronous belt. The first roller 21 is located above the second roller 22, and the rope is located between the first roller 21 and the second roller 22 and is in contact with both the first roller 21 and the second roller 22. When the second roller 22 rotates, the friction between it and the rope, and between the rope and the first roller 21, drives the rope to move towards the positioning seat 6, while simultaneously driving the first roller 21 to rotate synchronously. After the knotting is completed once, the feeding mechanism 2 automatically moves the rope forward a certain length to facilitate subsequent manual winding. After the feeding motor 23 drives the second roller 22 to rotate a set number of times, the feeding motor 23 stops running and stops feeding, ensuring that the rope moves forward the same length each time, ensuring that the length of rope used for knotting is the same each time, ensuring the uniformity of knotting production, and reducing rope waste.

[0023] In the above technical solution: the clamping mechanism 3 includes a clamping cylinder 31 and two opposing grippers 32. The clamping cylinder 31 drives the two grippers 32 to move relative to each other to clamp the rope. A transmission mechanism 10 is also provided on the base plate 1. The transmission mechanism 10 includes a transmission motor 101 and a transmission synchronous belt 102. The transmission motor 101 drives the transmission synchronous belt 102 to move. A transmission block 33 is fixed to the bottom of the clamping cylinder 31. A clamping plate 34 is installed on the transmission block 33. The transmission synchronous belt 102 is clamped by the clamping plate 34 and the transmission block 33, so that the transmission synchronous belt 102 drives the transmission block 33, the clamping cylinder 31, and the grippers 32 to move synchronously, realizing the forward and backward movement of the clamping mechanism 3. A first slide rail 11 is also fixed on the base plate 1. The bottom of the transmission block 33 is slidably mounted on the first slide rail 11, which guides the movement of the clamping mechanism 3.

[0024] In the above technical solution: a positioning groove 61 is formed on the positioning seat 6, and a rope winding groove 62 is connected to the two side walls of the positioning groove 61. The rope winding groove 62 is located on the side of the positioning seat 6 near the first winding mechanism 4 and the second winding mechanism 5. The positioning seat 6 is located between the first winding mechanism 4 and the second winding mechanism 5.

[0025] In the above technical solution: the first winding mechanism 4 includes a winding fixing seat 41, a first limiting plate 42, a first winding moving cylinder 43, and a first winding block 44. The winding fixing seat 41 is fixed on the base plate 1. The bottom of the first limiting plate 42 is installed on the winding fixing seat 41. A limiting opening is formed on the first limiting plate 42. The first winding block 44 is located inside the limiting opening. The limiting opening is arc-shaped, and the first winding block 44 is also arc-shaped. A winding moving block 45 is slidably arranged on the winding fixing seat 41. The first winding moving cylinder 43 is fixed on the base plate 1 and connected to the winding moving block 45. The first winding block 44 is located above the winding moving block 45. The first winding moving cylinder 43 drives the winding moving block 45 and the first winding block 44 to move up and down. When the first winding block 44 is wound with a rope, during the downward movement of the first winding block 44, the rope on the first winding block 44 comes into contact with the first limiting plate 42 and is limited by the first limiting plate 42. At this time, the rope does not move downward synchronously with the first winding block 44. When the first winding moving cylinder 43 drives the first winding block 44 to move downward to below the first limiting plate 42, the rope completely detaches from the first winding block 44.

[0026] In the above technical solution: the second winding mechanism 5 includes a second winding block 51, a second limiting plate 52, and a second winding moving cylinder 53. The mounting structure of the second winding block 51 is the same as that of the first winding block 44, and the mounting structure of the second limiting plate 52 is the same as that of the first limiting plate 44. The second winding moving cylinder 53 drives the second winding block 51 to move up and down.

[0027] In the above technical solution: the pressing mechanism 7 includes a pressing base 71, a pressing cylinder 72, and a pressing block 73. The bottom of the pressing base 71 is fixed to the base plate 1, the pressing cylinder 72 is mounted on the pressing base 71, and the pressing block 73 is mounted on the end of the piston rod of the pressing cylinder 72. A pressing inclined surface 74 is formed on the pressing block 73.

[0028] In the above technical solution: the rope pulling mechanism 8 includes a rope fixing seat 81, a rope pulling cylinder 82, a vertical moving cylinder 83, a rope pulling limit block 84, and a rope pulling rod 85. The rope fixing seat 81 is fixed on the base plate 1, and a rope pulling block 86 is slidably arranged on the rope fixing seat 81. The vertical moving cylinder 83 is installed on the base plate 1, and the piston rod of the vertical moving cylinder 83 is connected to the rope pulling block 86, driving the rope pulling block 86 to move up and down. The rope pulling cylinder 82 is installed on the rope pulling block 86, and a rope connecting block 87 is provided at the end of the piston rod of the rope pulling cylinder 82. The bottom of the rope pulling rod 85 is inserted into the rope connecting block 87, and the rope pulling cylinder 82 drives the rope connecting block 87 and the rope pulling rod 85 to move. The top of the pull rod 85 is also provided with a limiting protrusion 88. The rope is wound around the pull rod 85. The pull cylinder 82 drives the pull rod 85 to move backward and pull the rope. The limiting protrusion 88 prevents the rope from detaching from the pull rod 85 during the pulling process. The bottom of the pull rope limiting block 84 is connected to the base plate 1. The pull rope limiting block 84 is located on the path of the pull cylinder 82 driving the pull rod 85 to move backward and pull the rope. The pull rope limiting block 84 is provided with a moving notch 89. The width of the moving notch 89 is greater than the width of the limiting protrusion 88. During the movement of the pull rod 85, it enters the moving notch 89. At this time, the rope wound on the pull rod 85 is above the pull rope limiting block 84. The up-and-down moving cylinder 83 drives the rope moving block 86, the rope pulling cylinder 82, and the rope pulling rod 85 to move down synchronously. During the downward movement of the rope pulling rod 85, the rope wrapped around the rope pulling rod 85 contacts the rope pulling limit block 84 and stops moving down. When the rope pulling rod 85 moves to the point where the limit protrusion 88 is below the rope pulling limit block 84, the rope disengages from the rope pulling rod 85 and the limit protrusion 88.

[0029] In the above technical solution: the shearing mechanism 9 includes a pneumatic shear 91, a push cylinder 92, a movable slide block 93, and a second slide rail 94. Two second slide rails 94 are provided, and the second slide rails 94 are fixed to the base plate 1. The bottom of the movable slide block 93 is slidably mounted on the two second slide rails 94, allowing the movable slide block 93 to slide relative to the base plate 1. The push cylinder 92 is mounted on the movable slide block 93. A shearing moving block 95 is slidably mounted on the movable slide block 93. The push cylinder 92 drives the shearing moving block 95 to move. The pneumatic shear 91 is mounted on the shearing moving block 95, and the push cylinder 92 drives both the shearing moving block 95 and the pneumatic shear 91 to move.

[0030] The working process of this invention is as follows: The feeding motor 23 drives the second roller 22 to rotate, and the second roller 22 and the first roller 21 cooperate to feed the rope towards the positioning seat 6; after feeding is completed, the feeding motor 23 stops moving, and at this time the length of the fed rope is sufficient for the subsequent braiding process. The rope is manually straightened and clamped by two grippers 32. At this time, the tension cylinder 82 in the rope pulling mechanism 8 drives the rope pulling rod 85 to move towards the second winding block 51, so that the rope pulling rod 85 is located on the side of the second winding block 51 and waiting to be wound.

[0031] The rope is manually wound, first passing through the positioning groove 61, then pressing the rope tightly against the second winding block 51, and then wrapping the rope around the pull rod 85. At this point, the rope forms the first loop around the second winding block 51 and the pull rod 85. Next, the rope forms the second loop around the first winding block 44, and then the rope is pulled between the positioning seat 6 and the second winding block 51. The rope passes under the already wound rope, then wraps around the second loop from above, and then wraps around the first loop from below. Finally, the rope passes through the bottom of the second loop and the end of the rope is placed into the positioning groove 61, completing the rope winding. The specific winding method is as follows: Figure 4 The thicker part in the middle, Figure 4 The arrow on the thick line indicates the direction of winding. Figure 4 The section marked with a thin dashed line indicates that the rope passes under the previously wrapped rope.

[0032] Next, the pressing cylinder 72 of the pressing mechanism 7 drives the pressing block 73 to move forward, and the pressing inclined surface 74 presses down on the first loop on the outside of the second winding block 51; the first winding moving cylinder 43 drives the first winding block 44 to move down, and the second loop wound on the first winding block 44 contacts the first limiting plate 42 and is limited by the first limiting plate 42. At this time, the second loop does not move down synchronously with the first winding block 44. When the first winding moving cylinder 43 drives the first winding block 44 to move down to below the first limiting plate 42, the second loop completely disengages from the first winding block 44; the tension cylinder 82 of the rope pulling mechanism 8 drives the rope pulling rod 85 and the rope wound on it to move backward. During the backward movement of the rope, the second loop is gradually tightened. At this time, the first loop on the second winding block 51 is pressed and positioned by the pressing inclined surface 74 and does not move; after the second loop is tightened, the rope pulling rod 85 stops moving backward.

[0033] Then, the pressing cylinder 72 drives the pressing block 73 to move backward and disengage from the rope outside the second winding block 51 of the second winding mechanism 5. The second winding moving cylinder 53 drives the second winding block 51 to move downward, and the rope disengages from the second winding block 51. At this time, the length of the untightened rope is longer than the distance between the rope pulling rod 85 and the positioning seat 6. The up and down moving cylinder 83 drives the rope pulling rod 85 to move downward. The rope contacts the rope pulling limit block 84 and stops moving downward. When the rope pulling rod 85 moves to the point where the limit protrusion 88 is below the rope pulling limit block 84, the rope disengages from the rope pulling rod 85 and the limit protrusion 88. The transmission motor 101 drives the rope clamped by the gripper 32 to move away from the positioning seat 6, so that the rope that has disengaged from the second winding block 51 and the rope pulling rod 85 is tightened, completing the knot tightening. The knot is located in the rope winding groove 62. Finally, the cylinder 92 is pushed to move the pneumatic scissors 91, which cuts off the knot, completing the production of the knot. The knot is then manually removed from the positioning seat 6.

[0034] The first winding moving cylinder 43 drives the first winding block 44 to move upward and reset; the second winding moving cylinder 53 drives the second winding block 51 to move upward and reset; the up-down moving cylinder 83 drives the rope pulling rod 85 to move upward; the stretching cylinder 82 drives the rope pulling rod 85 to move towards the second winding block 51 and reset; the pushing cylinder 92 drives the pneumatic scissors 91 to move backward and reset; the feeding motor 23 drives the second roller 22 to rotate; the second roller 22 and the first roller 21 cooperate to feed the rope towards the positioning seat 6; the gripper 32 grips the rope and moves towards the positioning seat 6 and resets; after moving into position, the two grippers 32 move in opposite directions and release the rope; the rope is manually straightened to make it straight and begin winding; the gripper 32 grips the rope again and waits for the tightening process.

[0035] In this automated knotting equipment, two molds, a first winding block 44 and a second winding block 51, are set up to facilitate rope winding. At the same time, the automatic tightening, automatic knotting, and cutting of the knots are achieved through the cooperation of the clamping mechanism 3, the first winding mechanism 4, the second winding mechanism 5, the positioning seat 6, the pressing mechanism 7, the rope pulling mechanism 8, and the cutting mechanism 9. This ensures that the tightening force of the knots is uniform, thereby ensuring the uniformity and aesthetics of the knots. It realizes semi-automatic production of knots, greatly shortens the production time of knots, and improves the production efficiency of knots. After the feeding motor 23 drives the second roller 22 to rotate a set number of times, the feeding motor 23 stops running and stops feeding, ensuring that the length of the rope moving forward each time is equal, ensuring that the length of the rope used for knotting each time is equal, ensuring the uniformity of the knots produced, and reducing rope waste.
