Description

Technical Field

[0001] The present invention belongs to the technical field of glue coating for seamless underwear, and particularly relates to a production device for seamless underwear. Background Art

[0002] In the field of seamless underwear production, traditional equipment relies on distributed heating components (such as electric heating wires, heating tapes, etc.) to maintain the fluidity of the colloid, resulting in complex equipment structure, high energy consumption, and easy aging and damage of the heating elements, significantly increasing the maintenance cost; during the production process, the colloid is prone to staying in the pipeline and the dispensing head during shutdown or intermittent operation, solidifying and blocking due to heat dissipation and cooling, and frequent disassembly and cleaning are required, seriously reducing the production efficiency; in addition, it is not convenient to recover the residual colloid in the pipeline during shutdown, causing material waste and increasing the cleaning burden; these problems restrict the high efficiency and sustainability of seamless underwear production.

A regulating rod 176 is fixedly provided at the left end of the third sealing rod 175. A closing block 1761 is fixedly provided on the lower side of the right end and the upper side of the left end of the regulating rod 176. A feed groove 177 is formed on the left side of the dispensing head 16. The upper side of the feed groove 177 communicates with the sealing groove 161. Feed ports 178 are fixedly provided on both the upper and lower sides at the left end of the dispensing head 16. The feed groove 177 communicates the two feed ports 178. The left closing block 1761 matches the lower side of the feed groove 177, and the right closing block 1761 matches the upper side of the glue outlet groove 163.

A number of uniformly distributed small air holes 31 are provided at the upper end of the workbench 1. The number of small air holes 31 all communicate with the air cavity. The workbench 1 is equipped with a number of air pumping components. The longitudinal electric slide rail 12 and the transverse electric slide rail 14 can both install air pumping components.

[0030] The pump air assembly includes a telescopic corrugated airbag 32. Mounting blocks 33 are fixedly provided at both the front and rear ends of the longitudinal electric slide rail 12. Telescopic corrugated airbags 32 are assembled on both the front and rear sides of the gantry 13. The telescopic corrugated airbags 32 are fixedly assembled between the gantry 13 and the mounting blocks 33. Two intake check valves 34 respectively communicating with the two telescopic corrugated airbags 32 are fixedly provided on the lower side of the gantry 13. The intake check valves 34 ensure that gas only enters the air chamber through a number of small air holes 31 and then enters the telescopic corrugated airbags 32. The intake check valves 34 are equipped with air pipes 35 communicating with the air chamber. Both mounting blocks 33 are equipped with outlet check valves 36 communicating with the corresponding telescopic corrugated airbags 32. The outlet check valves 36 ensure that gas can flow out from the outlet check valves 36 when the telescopic corrugated airbags 32 are compressed. Due to the symmetrical arrangement of the two telescopic corrugated airbags 32, the adsorption function for seamless underwear fabric can be realized regardless of whether the electric slide rail moves forward, backward, left or right;

[0032] Working principle: When performing glue coating and dotting on seamless underwear fabric, two double-screw pumps 11 are started simultaneously to convey the heated glue in the forward direction. The glue is conveyed to the sealing groove 161 through the connecting pipe 18, the feed inlet 178 and the feed groove 177, and then conveyed downward through the sealing groove 161 to the flow groove 162, and finally flows out through the glue outlet groove 163 for glue coating and dotting operations; When the device is not used for glue coating and dotting on seamless underwear fabric, the return cylinder 17 is started to drive the connecting rod 173 and the first sealing rod 172 to move upward. When the first sealing rod 172 moves upward in the sealing groove 161, it can draw the glue upward, so that the glue in the glue outlet groove 163 moves upward into the flow groove 162. Then the shunt cylinder 171 is started to drive the second sealing rod 174 and the third sealing rod 175 to the right. After the second sealing rod 174 moves to the right, it can connect the sealing groove 161 and the flow groove 162 through the shunt groove 164, and the third sealing rod 175 can close the glue outlet groove 163 by relying on the lower right closing block 1761, and the upper left closing block 1761 closes the lower side of the feed groove 177, so that the flow groove 162 is partially communicated with the lower connecting pipe 18 through the adjusting rod 176. At this time, the double-screw pump 11 connected to the lower connecting pipe 18 is reversed, and the other double-screw pump 11 is driven forward, thus forming a loop, so that the glue in the connecting pipe 18 and the glue dispenser 16 continuously flows and is heated by the electric heating tank to avoid blockage of the pipe caused by glue cooling.
