Description

Technical Field

[0001] The invention belongs to the technical field of underwear mold cup production, and in particular relates to a pressure-controllable underwear mold cup compacting mechanism. Background Art

[0002] Underwear mold cups are an important part of underwear products. In today's highly refined industrial production, underwear mold cups are usually produced separately, or even by specialized manufacturers, and then delivered to underwear manufacturers for stitching to obtain complete underwear products. In this way, after the underwear mold cups are molded, they need to be packaged and delivered. Since the underwear mold cups are pressed from cloth, the underwear mold cups after molding are easily too fluffy after stacking, which causes a large waste of packaging space. Therefore, the packaging site usually needs to perform moderate compaction operations on the underwear mold cups to be packaged to improve space utilization. However, this operation has certain requirements. If the compaction operation pressure is too small, the expected effect cannot be achieved. If the compaction operation pressure is too large, it may cause damage to the underwear mold cups that have completed the molding process. Therefore, the pressure of this operation needs to be controlled within a certain range. Summary of the invention

[0003] The present invention provides a pressure-controllable underwear mold cup compacting mechanism to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A pressure-controllable underwear mold cup compacting mechanism comprises a packaging part, a compacting part, a rod system and an adjusting part. The compacting part is located above the packaging part and connected to the rod system. The adjusting part is connected to the rod system and adjusts the pressure transmitted by the rod system.

[0005] The packaging part includes a conveyor belt and a packaging box. The conveyor belt is located above the side of the packaging box. The finished molded underwear cups from the conveyor belt fall into the packaging box one by one. When the underwear cups in the packaging box are stacked to a certain extent, compaction operation is required. The compaction part includes a pressing plate, a column, two ears and a guide plate. The pressing plate has a shape similar to that of the underwear cups. The pressing plate is located directly above the packaging box. The top of the pressing plate is connected to the column. The top of the column has two ears, which are hinged to the rod system. The rod system includes a lower pull rod, a three-link rod, an upper pull rod and a driving rod. The bottom of the lower pull rod is hinged to the two ears of the pressing plate, the top of the lower pull rod is hinged to one end of the three-link rod, the middle of the three-link rod is hinged to the adjustment part, the other end of the three-link rod is hinged to the upper pull rod, and the top of the upper pull rod is hinged to the driving rod. The driving rod is connected to a power source, and the power source drives the driving rod to rotate, and further drives the rod system to move, and then drives the compaction part to move, completing the compaction operation. The adjusting part comprises a control rod, a bracket and a spring. The bottom of the control rod is hinged with the middle of the three-link rod. The control rod is sleeved and installed on the bracket. The front end of the bracket has two clamping plates. Two springs are sleeved on the control rod and the spring is installed between the two clamping plates.

[0006] Furthermore, the upright column is sleeved and installed in the guide plate, and the guide plate guides the movement of the pressing plate to ensure that the pressing plate always keeps vertical up and down movement.

[0007] Furthermore, the control rod has a threaded area in the middle, a round nut is installed on the threaded area, and two springs are installed at both ends of the round nut respectively. Adjusting the height of the round nut can adjust the preload force of the upper and lower springs, thereby adjusting the force required for the middle compression spring of the triple rod, thereby adjusting the pressing force of the pressure plate on the underwear mold cup.

[0008] The beneficial effects of the present invention are: The present invention is used for packaging and compacting operations after the underwear mold cup is molded and formed. It has a set of common crank-connecting rod reciprocating mechanisms. On the basis of the crank-connecting rod reciprocating mechanism, the middle connecting rod is improved into a three-link rod supported by a spring. The spring is installed in the middle of the three-link rod through a rod. When the pressure plate device compacts the underwear mold cup to a certain extent, the force fed back from the rod will push the spring to compress, so that the rod will no longer continue to compact downward, and then the pressure of the pressure plate on the underwear mold cup is effectively controlled. The appropriate compaction strength can be obtained by selecting a spring with an appropriate elastic coefficient, and the preload force of the spring can be fine-tuned by adjusting the position of the middle round nut, thereby adjusting the maximum compaction pressure acting on the underwear mold cup.

[0011] See also Figure 1-Figure 3The pressure-controllable underwear mold cup compacting mechanism shown includes a packaging part 10, a compacting part 20, a rod system 30 and an adjusting part 40. The compacting part 20 is located above the packaging part 10 and connected to the rod system 30. The adjusting part 40 is connected to the rod system 30 to adjust the pressure transmitted by the rod system 30.

[0012] The packaging section 10 includes a conveyor belt 11 and a packaging box 12. The conveyor belt 11 is located above the side of the packaging box 12. The finished molded underwear cups from the conveyor belt 11 fall into the packaging box 12 one by one. When the underwear cups in the packaging box 12 are stacked to a certain extent, compaction operation is required.

[0013] The compacting part 20 includes a pressing plate 21, a column 22, two ears 23 and a guide plate 24. The pressing plate 21 has a shape similar to that of the underwear mold cup. A pressing plate 21 of a suitable shape is selected according to the shape of the underwear mold cup to be packaged to avoid damaging the molded underwear mold cup during the compaction process. The pressing plate 21 is located directly above the packaging box 21. The top of the pressing plate 21 is connected to the column 22, and the column 22 is installed in the guide plate 24. The guide plate 24 guides the movement of the pressing plate 21 to ensure that the pressing plate 21 always maintains vertical up and down movement. The top of the column 22 has two ears 23, and the two ears 23 are hinged to the rod system 30.

[0014] The rod system 30 includes a lower pull rod 31, a three-link rod 32, an upper pull rod 33 and a driving rod 34. The bottom of the lower pull rod 31 is hinged to the two ears 23 of the pressure plate 21, the top of the lower pull rod 31 is hinged to one end of the three-link rod 32, the middle of the three-link rod 32 is hinged to the adjustment part 40, the other end of the three-link rod 32 is hinged to the upper pull rod 33, and the top of the upper pull rod 33 is hinged to the driving rod 34. The driving rod 34 is connected to a power source, and the power source drives the driving rod 34 to rotate, and further drives the rod system 30 to move, and then drives the compacting part 20 to move to complete the compaction operation.

[0015] The adjustment part 40 includes a control rod 41, a bracket 42 and a spring 43. The bottom of the control rod 41 is hinged to the middle of the three-link rod 32. The control rod 41 is sleeved and installed on the bracket 42. The front end of the bracket 42 has two clamping plates 421. The control rod 41 is sleeved with two springs 43, and the spring 43 is installed between the two clamping plates 421.

Adjusting the height of the round nut 412 can adjust the preload force of the upper and lower springs 43, thereby adjusting the force required for the compression spring in the middle of the three-link rod 32, and thereby adjusting the pressing force of the pressing plate 21 on the underwear mold cup.

[0016] The working principle of the present invention is: the underwear mold cups that have completed mold pressing are placed on a conveyor belt and transported to a packaging box. The power source drives the upper pull rod 33 to swing through the driving rod 34, and the upper pull rod 33 drives the three-link rod 32 to swing. The three-link rod 32 rotates with the middle hinge point as the fulcrum, and the other end of the three-link rod 32 drives the lower pull rod 31 to swing, and the lower pull rod 31 drives the pressing plate 21 to reciprocate up and down. The pressing plate 21 compacts the underwear mold cups in the packaging box 12 during the movement. The two springs 43 play a balancing role on the fulcrum of the three-link rod 32. When the compacting operation pressure of the pressing plate 21 on the underwear mold cup exceeds the elastic force of the spring 43, the fulcrum of the three-link rod 32 moves upward, and the pressing plate 21 no longer compacts the underwear mold cup beyond the range. By adjusting the position of the round nut 412, the preload force of the upper and lower springs 43 can be adjusted, and then the contraction position of the fulcrum of the three-link rod 32 is adjusted, and the maximum compacting force acting on the underwear mold cup is adjusted.
