Description

TECHNICAL FIELD

[0001] The present application relates to the field of clothing equipment, in particular to an automatic printing and gluing machine and a method for processing mark-free underwear. BACKGROUND

[0002] The fabric used by the mark-free underwear is a double-layer fabric, including a bottom layer fabric and a top layer fabric, and the two side fabrics are connected by glue, and the shape of the glue in the fabric is determined according to the style of the underwear.

[0003] At present, the production process of the mark-free underwear is roughly as follows:

[0004] Cutting:

[0005] Through manual cutting, a single bottom layer fabric is obtained by cutting the bottom layer fabric roll, and a single top layer fabric is obtained by cutting the top layer fabric roll. The bottom surface of each bottom layer fabric and top layer fabric is attached with a shaping base film, which is used to ensure that the fabric maintains a sheet structure, so that the fabric can be stably transferred between subsequent mechanisms;

[0006] Punching and positioning:

[0007] Through manual punching and positioning, two positioning holes are punched on each top layer fabric and bottom layer fabric on the punching mechanism;

[0008] Gluing:

[0009] Through manual gluing, each bottom layer fabric is placed in the silk screen gluing machine, and the bottom layer fabric is positioned by the positioning hole when it is installed in the gluing machine. Then, the gluing machine is used to brush glue on the surface of the bottom layer fabric, and the pattern on the silk screen determines the shape of the glue on the surface of the bottom layer fabric;

[0010] Flattening:

[0011] Through manual flattening, the bottom layer fabric with glue is first placed in the flattening mechanism, and the bottom layer fabric is positioned in the flattening mechanism through the positioning hole. Then, the top layer fabric is attached to the bottom layer fabric, and the top layer fabric is also positioned through the positioning hole. Then, the flattening mechanism is pressed to flatten the top layer fabric and the bottom layer fabric into a composite sheet material;

[0012] Punching:

[0013] Through manual punching, the composite sheet material is loaded into the punching machine, and the composite sheet material is positioned in the punching machine through the positioning hole. The punching machine is used to cut off the excess fabric on the sheet fabric, thereby obtaining the finished composite sheet material.

[0014] The finished sheet material is subjected to subsequent process treatment of the mark-free underwear, and finally the shaping base film of the top layer fabric and the bottom layer fabric is torn off, at which time the mark-free underwear becomes soft.

[0015] The following defects exist in the conventional composite sheet production process:

[0016] 1. The cutting machine, punching machine, glue brushing machine, leveling machine and punching machine used in the clothing production process are independent devices, and a large amount of manual labor is required to load and unload the sheet-shaped double-layer composite fabric in the clothing production process, which is relatively low in efficiency and cannot realize automation.

[0017] 2. In the clothing production process, the fabric is first cut to obtain a sheet-shaped fabric, therefore, the upper fabric and the bottom fabric used in the conventional clothing production process are provided with a positioning film, and the fabric with the positioning film has a relatively high cost, because the fabric from the fabric factory does not have a positioning film, and the positioning film needs to be added later, which increases the clothing production cost. SUMMARY

[0185] ​The cutting cloth translation driving assembly adjusts the longitudinal position of the electric circular cutter 54 on the rack, and the transverse translation driving assembly adjusts the transverse position of the electric circular cutter 54 on the rack. For the composite sheet material after punching, the cutting area of the composite material is transversely cut by the electric circular cutter 54, so as to obtain a single composite sheet material.

[0186] Specifically, as an optional implementation manner in the embodiment, as shown in Figure 8 and Figure 9 The first pulling mechanism 6A includes

[0187] A pair of material rollers are rotationally arranged on the rack;

The pulling translation driving assembly is adapted to drive the fifth support 62 to move longitudinally along the rack, so as to drive the clamped fabric and the material dragging belt 61 to move together.

[0192] The working principle of the pulling translation driving assembly is the same as that of the punching translation driving assembly, and the pulling translation driving assembly and the punching translation driving assembly share the guide rail and the rack.

[0193] The transverse positions of the two material clamping air cylinders 64 on the fifth support 62 are adjusted in advance, and the clamping point of the clamping block avoids the position of the glue brushing.

[0194] The working process of the first pulling mechanism 6A is as follows:

[0195] The pulling translation driving assembly controls the fifth support 62 to move upstream, and the two material clamping air cylinders 64 clamp the double-layer composite fabric and the material dragging belt 61 at the bottom of the fifth support 62. Then, the pulling translation driving assembly controls the fifth support 62 to move downstream, so as to drive the double-layer composite fabric and the material dragging belt 61 to move together. After pulling to the target position, the material clamping air cylinders 64 are loosened, and then reset to the upstream position again. Thus, the double-layer composite fabric is pulled.

[0211] As a part of the second unwinding mechanism 7B, as shown in the figure, a guide roller 76 is further included, the two ends of the guide roller 76 are fixedly connected with the frame, and after the upper layer of fabric 1B output from the first unwinding mechanism 7A passes through the guide roller 76, the upper layer of fabric 1B enters the flattening mechanism 3 in a horizontal state.

[0213] When the fabric clamping mechanism is clamped, the second unwinding mechanism 6B moves upward to clamp the bottom layer of fabric 1A.
