Description

Technical Field

[0001] The utility model belongs to the technical field of clothing production and relates to an automatic knotting equipment for button knots of Chinese frog buttons. Background Art

[0002] Button knots, also known as button loops, or knots and loops, are a type of button used in traditional clothing to fasten the front of the garment or for decoration, and are usually used in clothing such as cheongsams and Tang suits. The button knot includes a button band and a knot. The button band and the knot are sewn on both sides of the front of the garment and face each other. The button band is formed by folding a rope in half, and the knot is formed by braiding and tightening a rope into a spherical shape in a certain step. The knot is buckled into the button band to complete the connection of the two sides of the front of the garment. The braiding process of the knot has many handicraft steps and needs to be braided manually, resulting in a long production time, low efficiency, and high labor production cost of the knot. Moreover, when braiding manually, due to the different strengths of manually tightening the rope knot, the sizes of the completed knots are different, affecting the uniformity and aesthetics of the knots.

Detailed implementation mode

[0020] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0021] As Figures 1-4 shown, the automatic knotting equipment for the button of this plate buckle includes a bottom 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 installed on the bottom plate 1. The first winding mechanism 4 and the second winding mechanism 5 are respectively located on both sides of the front part of the positioning seat 6 and are arranged oppositely. The pressing mechanism 7, the rope pulling mechanism 8, and the cutting mechanism 9 are arranged in sequence 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 sequence on a straight line. The clamping mechanism 3 is located directly behind the positioning seat 6, and the feeding mechanism 2 is located directly behind the clamping mechanism 3.

[0022] In the above technical solution: A plurality of side plates 12 are installed on the bottom 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 structures on the bottom plate 1. The controller 14 includes a control screen for controlling the operation and stop of each mechanism.

[0023] 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 bottom plate 1. Both ends of the first roller 21 and the second roller 22 are hinged on the two side plates of the feeding seat 24. The feeding motor 23 is fixed on the bottom plate 1, and the feeding motor 23 drives the second roller 22 to rotate through a synchronous belt. The first roller 21 is located above the second roller 22. 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, it drives the rope to move towards the positioning seat 6 by the friction force between it and the rope, and between the rope and the first roller 21, and at the same time drives the first roller 21 to rotate synchronously. After the knotting completes one braiding, the feeding mechanism 2 automatically drives the rope to move forward a certain length, facilitating subsequent manual winding. After the feeding motor 23 drives the second roller 22 to rotate a set number of turns, the feeding motor 23 stops running and stops feeding, ensuring that the length of the rope moved forward each time is equal, ensuring that the length of the rope used for each braiding is equal, ensuring the uniformity after knotting production, and also reducing the waste of the rope.

[0024] In the above technical solution: The clamping mechanism 3 includes a clamping cylinder 31 and two oppositely arranged clamping claws 32. The clamping cylinder 31 drives the two clamping claws 32 to move relatively to clamp the rope. A transmission mechanism 10 is also provided on the bottom 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 at the bottom of the clamping cylinder 31, and a clamping piece 34 is installed on the transmission block 33. The transmission synchronous belt 102 is clamped by the clamping piece 34 and the transmission block 33, so that the transmission synchronous belt 102 drives the transmission block 33, the clamping cylinder 31 and the clamping claws 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 bottom plate 1. The bottom of the transmission block 33 is slidably arranged on the first slide rail 11, playing a role in guiding the movement of the clamping mechanism 3.

[0025] In the above technical solution: A positioning groove 61 is made on the positioning seat 6. Rope winding grooves 62 are connected to the two side walls of the positioning groove 61. The rope winding grooves 62 are located on the side of the positioning seat 6 close to 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.

[0026] In the above technical solution: The first winding mechanism 4 includes a winding fixed seat 41, a first limiting plate 42, a first winding moving cylinder 43 and a first winding block 44. The winding fixed seat 41 is fixed on the bottom plate 1. The bottom of the first limiting plate 42 is mounted on the winding fixed seat 41. A limiting opening is formed on the first limiting plate 42. The first winding block 44 is located within 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 fixed seat 41. The first winding moving cylinder 43 is fixed on the bottom 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 a rope is wound around the first winding block 44, during the downward movement of the first winding block 44, the rope 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 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 below the first limiting plate 42, the rope completely disengages from the first winding block 44.

[0027] 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 installation structure of the second winding block 51 is the same as that of the first winding block 44, and the installation structure of the second limiting plate 52 is the same as that of the first limiting plate 42. The second winding moving cylinder 53 drives the second winding block 51 to move up and down.

[0028] In the above technical solution: The material pressing mechanism 7 includes a material pressing fixed seat 71, a material pressing cylinder 72 and a material pressing block 73.

The material pressing block 73 is mounted at the end of the piston rod of the material pressing cylinder 72. A material pressing inclined surface 74 is formed on the material pressing block 73.

[0029] In the above technical solution: The rope pulling mechanism 8 includes a rope pulling fixed seat 81, a rope pulling cylinder 82, an up-and-down moving cylinder 83, a rope pulling limit block 84 and a rope pulling rod 85. The rope pulling fixed seat 81 is fixed on the bottom plate 1. A rope pulling moving block 86 is slidably arranged on the rope pulling fixed seat 81. The up-and-down moving cylinder 83 is installed on the bottom plate 1. The piston rod of the up-and-down moving cylinder 83 is connected to the rope pulling moving block 86 and drives the rope pulling moving block 86 to move up and down. The rope pulling cylinder 82 is installed on the rope pulling moving block 86. A rope pulling connection 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 pulling connection block 87. The rope pulling cylinder 82 drives the rope pulling connection block 87 and the rope pulling rod 85 to move. A limit convex block 88 is also made at the top of the rope pulling rod 85. The rope is wound around the rope pulling rod 85. The rope pulling cylinder 82 drives the rope pulling rod 85 to move backward to pull the rope. The limit convex block 88 prevents the rope from detaching from the rope pulling rod 85 during the rope pulling process. The bottom of the rope pulling limit block 84 is connected to the bottom plate 1. The rope pulling limit block 84 is located on the path of the rope pulling rod 85 being pulled backward by the rope pulling cylinder 82 to draw the rope. A moving notch 89 is made on the rope pulling limit block 84. The width of the moving notch 89 is greater than the width of the limit convex block 88. The rope pulling rod 85 enters the moving notch 89 during the movement. At this time, the rope wound around the rope pulling rod 85 is located above the rope pulling limit block 84. The up-and-down moving cylinder 83 drives the rope pulling 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 wound around the rope pulling rod 85 contacts the rope pulling limit block 84 and stops moving downward. When the rope pulling rod 85 moves to the position where the limit convex block 88 is located below the rope pulling limit block 84, the rope detaches from the rope pulling rod 85 and the limit convex block 88.

[0030] In the above technical solution: The material cutting mechanism 9 includes a pneumatic scissors 91, a pushing cylinder 92, a moving slide 93 and a second slide rail 94. There are two second slide rails 94. The second slide rails 94 are fixed on the bottom plate 1. The bottom of the moving slide 93 is slidably arranged on the two second slide rails 94. The moving slide 93 can slide relative to the bottom plate 1. The pushing cylinder 92 is installed on the moving slide 93. A material cutting moving block 95 is slidably arranged on the moving slide 93. The pushing cylinder 92 drives the material cutting moving block 95 to move. The pneumatic scissors 91 are installed on the material cutting moving block 95. The pushing cylinder 92 drives the material cutting moving block 95 and the pneumatic scissors 91 to move.

[0031] The working process of the present utility model is as follows: The feeding motor 23 drives the second roller 22 to rotate. The second roller 22 and the first roller 21 cooperate to send the rope in the direction close to the positioning seat 6; after the feeding is completed, the feeding motor 23 stops moving. At this time, the length of the sent rope is sufficient for the subsequent braiding process. The rope is manually straightened and clamped by the two clamping jaws 32. At this time, the stretching cylinder 82 in the rope pulling mechanism 8 drives the rope pulling rod 85 to move in the direction close to the second winding block 51, so that the rope pulling rod 85 is located on the side of the second winding block 51 waiting for winding.

[0032] The rope is manually wound, first the rope is passed through the positioning groove 61, then the rope is made close to the second winding block 51, and then the rope is wound around the rope pulling rod 85. At this time, the rope is wound around the second winding block 51 and the rope pulling rod 85 to form a first loop; then the rope is wound around the first winding block 44 to form a second loop, and then the rope is pulled between the positioning seat 6 and the second winding block 51, and the rope is passed out from the bottom of the wound rope, and the rope is wound around the second loop from the top, and then the first loop is wound from the bottom, and finally the rope is passed out from the bottom of the second loop, and the end of the rope is placed in the positioning groove 61 to complete the winding of the rope; the specific winding method is as follows Figure 4 The bold part in Figure 4 The arrow on the medium thick line indicates the winding direction. Figure 4 The dotted portion of the thin middle line indicates that the rope passes under the previously wound rope.

[0033] Then, the pressing cylinder 72 of the pressing mechanism 7 drives the pressing block 73 to move forward, and the pressing slope 74 presses the first circle on the outside of the second winding block 51; the first winding moving cylinder 43 drives the first winding block 44 to move downward, and the second circle 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 circle 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 second circle is completely separated from the first winding block 44; the stretching cylinder 82 of the rope pulling mechanism 8 drives the rope pulling rod 85 and the rope wound thereon to move backward. The rope gradually tightens the second circle during the backward movement process. At this time, the first circle on the second winding block 51 is held in place by the pressing slope 74 and does not move; after the second circle is tightened, the rope pulling rod 85 stops moving backward.

[0034] Then, the pressing cylinder 72 drives the pressing block 73 to move backward and disengage the rope on the outside of the second winding block 51 of the second winding mechanism 5, and the second winding moving cylinder 53 drives the second winding block 51 to move downward, and the rope is disengaged 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, and the rope contacts the rope-pulling limit block 84 and stops moving downward. When the rope-pulling rod 85 moves to the limit protrusion 88 and is located below the rope-pulling limit block 84, the rope is disengaged from the rope-pulling rod 85 and the limit protrusion 88; the transmission motor 101 drives the rope clamped by the clamping claw 32 to move in a direction away from the positioning seat 6, so that the rope that is disengaged from the second winding block 51 and the rope-pulling rod 85 is tightened, completing the braiding and tightening of the knot, and the knot is located in the rope winding groove 62. Finally, the air cylinder 92 is pushed to drive the pneumatic scissors 91 to move, and the pneumatic scissors 91 cuts off the knot, completing the production of the knot, and the knot is manually removed from the positioning seat 6.

[0035] 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-and-down moving cylinder 83 drives the rope pulling rod 85 to move upward, and the stretching cylinder 82 drives the rope pulling rod 85 to move and reset in the direction close to the second winding block 51; 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, and the second roller 22 and the first roller 21 cooperate to send the rope in the direction close to the positioning seat 6; the clamping jaws 32 clamp the rope and move and reset in the direction close to the positioning seat 6. After moving in place, the two clamping jaws 32 move away from each other to release the rope; manually straighten the rope to make it straight and start winding, and the clamping jaws 32 re-clamp the rope and wait for the tightening process.

[0036] In the knotting automation equipment of this disc button knot, by setting two molds, namely the first winding block 44 and the second winding block 51, it is convenient for the winding of the rope. At the same time, through the cooperation of the clamping mechanism 3, the first winding mechanism 4, the second winding mechanism 5, the positioning seat 6, the material pressing mechanism 7, the rope pulling mechanism 8, and the material cutting mechanism 9, the automatic tightening, automatic knotting and shearing of the knot are realized, ensuring the uniform strength of the tightened rope knot, thus ensuring the uniformity and aesthetics of the knot, realizing the semi-automatic production of the knot, greatly shortening the production time of the knot, and improving the production efficiency of the knot; after the feeding motor 23 drives the second roller 22 to rotate a set number of turns, 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 after the knot is produced, and also reducing the waste of the rope.
