[0035] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0036] like Figure 1 As shown, a cold knife bag opening machine includes a machine body 100, on which a sewing machine 110, a bag opening mechanism 120 for cutting clothes to form seams, a folding mechanism 130 for folding the seams, and a clamping mechanism 140 for clamping and fixing clothes and moving the clothes to various stations are arranged, wherein the bag opening mechanism 120 has a reciprocating cutter to slit the clothes clamped by the clamping mechanism 140, and the clamping mechanism 140 is a prior art and will not be described in detail here. After the bag-opening clothes are fixed by the clamping mechanism 140, they are moved to the bag opening mechanism 120, the folding mechanism 130 and the sewing machine 110 in sequence to realize the bag-opening and seaming operation.

[0037] In order to realize that the bag opening mechanism 120 can open seams in all directions of the clothes and improve its practicality, Figure 2As shown, a steering mechanism 150 is installed at the bottom of the bag opening mechanism 120. By rotating the steering mechanism 150, the angle of the bag opening mechanism 120 is changed, and the direction of the cutter on the bag opening mechanism 120 is further changed, that is, the seam cutting in different directions is achieved. The steering mechanism 150 includes a seat body 151 installed on the machine body 100, and a cylinder body 152 is rotatably connected to the seat body 151. The bag opening mechanism 120 is installed on the upper surface of the cylinder body 152. The outer circumferential surface of the cylinder body 152 is wound with a synchronous belt 154. The cylinder body 152 is driven to rotate by a first motor 153, and the synchronous belt 154 is wound on the output shaft of the first motor 153. The first motor 153 is a stepping motor, which drives the first motor 153 and drives the cylinder body 152 to rotate through the synchronous belt 154, thereby changing the working angle of the bag opening mechanism 120.

[0038] The bag opening mechanism 120 includes a mounting seat 121, a knife rod 122, a cutter 123, a motor 124, a crank 125 and a connecting rod 126, wherein the mounting seat 121 is mounted on the cylinder 152 by bolt fixing, a vertical through hole is provided at the center position of the mounting seat 121, and the knife rod 122 is slidably installed in the through hole. In order to reduce the wear between the knife rod 122 and the mounting seat 121, a copper sleeve is embedded in the through hole, and the knife rod 122 is installed in the mounting seat 121 through the copper sleeve.

[0039] A cutter 123 is installed at the bottom end of the knife bar 122, and a hinge seat is installed at the top end of the knife bar 122. The motor 124 is fixedly installed on one side of the top of the mounting seat 121, and the crank 125 is installed on the shaft of the motor 124. One end of the connecting rod 126 is rotatably connected to the crank 125, and the other end is rotatably connected to the hinge seat. In other words, the circular motion of the motor 124 is converted into the reciprocating motion of the knife bar 122 through the crank 125 and the connecting rod 126, thereby realizing the cloth cutting action.

[0040] Specifically, Figure 3-Figure 6As shown, the folding mechanism 130 includes a lifting seat 131 that can slide up and down along the mounting surface of the machine body 100, a second motor 132 is arranged on the mounting surface of the machine body 100, and a gear rack 133 meshing with the output shaft of the second motor 132 is arranged on the opposite surface of the lifting seat 131. The second motor 132 is a lifting motor, and the output shaft of the second motor 132 rotates, transmitting the motion to the gear rack 133, driving the lifting seat 131 to move up and down: the lifting seat 131 is installed with a main folding cylinder 135 for driving the main folding assembly and two side folding cylinders 136 for driving the side folding assemblies, and the side folding cylinders 136 are located on both sides of the main folding cylinder 135. The bottom surface of the lifting seat 131 is provided with parallel first guide rails 134, each of which is connected to a folding plate 137 through a slider, and the folding plate 137 is connected to the clamping finger 1351 of the main folding cylinder 135 through a connecting block; there are two clamping fingers 1351, which are symmetrical about the longitudinal axis of the main folding cylinder 135. The folding plate 137 is connected to the folding plate 139 through a mounting plate 138, and the two folding plates 139 form an inverted Y shape, and there is an angle at the contact point with the seam of the clothes, so that the seam can more easily enter the angle of the Y shape, which is convenient for the seam to be tilted, and then the folding effect is achieved through the two bottom edges of the Y shape. The side folding assembly includes a side folding cylinder 136 slidably connected to the bottom plate of the lifting seat 131. The bottom surface of the bottom plate of the lifting seat 131 is slidably connected to the horizontal moving seat 140 through a slider 141. The output shaft of the side folding cylinder 136 is connected to the horizontal moving seat 140 through a push rod 1361. The side folding cylinder 136 drives the horizontal moving seat 140 to move horizontally along the bottom plate of the lifting seat 131. The horizontal moving seat 140 has a vertically arranged horizontal section and a vertical section. The horizontal end is connected to the slider 141, and the vertical section extends vertically downward. The vertical section is connected to an upper and lower driving cylinder 142. The output end of the upper and lower driving cylinder 142 is connected to a small folding plate seat 143. The upper and lower driving cylinders 142 drive the small folding plate seat 143 to move up and down, and the bottom of the small folding plate seat 143 is connected to a folding plate 144.

[0041] Working process:

[0042] 1. Place the clothes on the clamping mechanism and fix them to prevent displacement;

[0043] 2. The clamping mechanism moves the clothes horizontally to the bottom of the bag opening mechanism. At this time, the cutter moves back and forth to pierce the clothes and form an incision on the clothes; (the incision is like the cutter along the Figure 8 The cutting line in the

[0044] 3. The clamping mechanism moves the clothes horizontally to the bottom of the folding mechanism. After it is lifted and lowered to the corresponding position, the main folding cylinder drives the main folding assembly to perform long folding; then the side folding cylinder drives the side folding assembly to perform short folding; 4. After the folding is completed, the side folding assembly is reset first, then the main folding assembly is reset, and finally the lifting seat is reset; 5. The clamping mechanism moves the folded clothes to the sewing machine for sewing.
