[0027] like Figure 1As shown, a sleeve seam press and its pressure detection system include a movable base 1 and a frame 2. The frame 2 is positioned above the movable base 1.

The auxiliary flipping component can drive the auxiliary support component by flipping. As needed, the auxiliary support component can fix or loosen the garment to be processed. The displacement output component can perform linear displacement. Through linear displacement, the flipping base plate 4 is driven. The cold upper mold 5 and hot upper mold 6 below the flipping base plate 4 move accordingly. The cold and hot mold flipping component provides corresponding support for the cold upper mold 5 and hot upper mold 6. The positions of the cold upper mold 5 and hot upper mold 6 can be exchanged as needed to perform cold or hot pressing on the garment placed on the lower mold 3.

[0029] like Figure 2 As shown, the lower mold mounting assembly includes a lower mold platform 9, a lower mold base plate 10, and a lower mold abutment plate 11. The lower mold platform 9 is bolted to the bottom of the frame 2, and the lower mold base plate 10 is bolted to the lower mold platform 9. Two lower molds 3 are set on the upper surface of the lower mold base plate 10. There are several lower mold abutment plates 11, which are distributed along the shape of the bottom of the lower mold 3.

[0030] The lower die table 9 provides support for the corresponding parts, the lower die base plate 10 provides support for the two lower dies 3, and the lower die abutment plate 11 is distributed along the bottom of the lower die to form multi-point support, effectively limiting the displacement of the lower die 3 during the stamping process.

[0031] like Figure 2 and Figure 3As shown, the auxiliary support assembly includes an auxiliary support base 12, an auxiliary bearing 13, and an auxiliary support screw 14. The auxiliary bearing 13 is rotatably connected to the auxiliary support base 12, and one end of the auxiliary support screw 14 is threaded to the auxiliary support base 12, while the other end is threaded to the auxiliary tilting assembly.

[0032] The auxiliary support base 12 provides corresponding support for the auxiliary bearing 13. The auxiliary bearing 13 can tighten or loosen the garment to be processed. The auxiliary support screw 14 can be connected to the auxiliary flipping assembly, so that the auxiliary flipping assembly can drive the auxiliary support assembly to rotate.

[0033] like Figure 2 and Figure 3 As shown, the auxiliary tilting assembly includes an auxiliary tilting cylinder 15, a cylinder connector 16, an L-shaped connecting plate 17, a tilting arm 18, a bearing base 19, an auxiliary support tilting seat 20, and a tilting adjustment seat 21. The piston rod of the auxiliary tilting cylinder 15 is fixedly connected to the cylinder connector 16. There are two L-shaped connecting plates 17. One end of each L-shaped connecting plate 17 is bolted to the lower surface of the lower mold base plate 10, and the other end is bolted to the auxiliary tilting cylinder 15. There are two tilting arms 18. One end of each tilting arm 18 is rotatably connected to the cylinder connector 16 via a pin, and the other end is rotatably connected to the bearing base 19 via a rotating shaft. There are two bearing bases 19. The auxiliary support tilting seat 20 is located between the two bearing bases 19 and is rotatably connected to the rotating shaft. The lower surface of the tilting adjustment seat 21 is bolted to the auxiliary support tilting seat 20, and its upper surface is threaded to the support screw.

[0034] The cylinder connector 16 is a fisheye connector, and the L-shaped connecting plate 17 provides corresponding support for the tilting cylinder. The tilting cylinder can drive the tilting arm 18 to rotate through the cylinder connector 16 and the pin shaft. Further rotation of the tilting arm 18 can drive the auxiliary support tilting seat 20 and the tilting adjustment seat 21 to rotate. The tilting adjustment seat 21 is threaded to the auxiliary support screw 14, which can ultimately drive the auxiliary support assembly to rotate, thereby fixing or loosening the clothes to be processed on the lower mold 3. The bearing base 19 and the rotating shaft fix the corresponding components.

[0035] like Figure 4 and Figure 5 As shown, the displacement output assembly includes an output cylinder 22, a cylinder base 23, a base connecting plate 24, mounting bolts 25, and a compression spring 26. The output cylinder 22 passes through the top of the frame 2. The cylinder base 23 is set on the piston rod of the output cylinder 22. The cylinder base 23 is bolted to the base connecting plate 24. There are several mounting bolts 25, which are used to fix the base connecting plate 24 and the flip base plate 4. Each mounting bolt 25 is fitted with a compression spring 26.

[0036] The output cylinder 22 provides the corresponding power, the cylinder base 23 and the base connecting plate 24 provide support for the drive cylinder, and the power of the output cylinder 22 can be effectively transmitted to the flip base plate 4 by the mounting bolt 25. The compression spring 26 can absorb some energy and play a role in buffering and shock absorption, protecting the components from damage.

[0037] like Figure 4 and Figure 5 As shown, the hot and cold mold flipping assembly includes a rotating shaft base plate 27, a motor base 28, a flipping motor 29, a driving wheel 30, a driven wheel 31, and a timing belt 32. The rotating shaft base plate 27 is bolted to the lower surface of the flipping base plate 4, and the motor base 28 is bolted to the upper surface of the flipping base plate 4. The driven wheel 31 is located on one side of the rotating shaft base plate 27 and is rotatably connected to the rotating main shaft 8. The flipping motor 29 is bolted to the motor base 28, and its output shaft is rotatably connected to the driving wheel 30. One end of the timing belt 32 is rotatably connected to the driving wheel 30, and the other end is rotatably connected to the driven wheel 31.

[0038] The rotating shaft base plate 27 provides corresponding support for the rotating main shaft 8 and the driven wheel 31, and the motor base 28 provides corresponding support for the flip motor 29. The power output of the flip motor 29 is sent to the driving wheel 30. The driving wheel 30 drives the driven wheel 31 through the synchronous belt 32, which in turn drives the rotating main shaft 8. The rotation of the rotating main shaft 8 can realize the alternation of the cold upper mold 5 and the hot upper mold 6, and perform cold pressing or hot pressing on the clothes to be processed on the lower mold 3 as needed.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the pressure detection system includes an aluminum support 33, a light curtain support 34, a light curtain sensor 35, a sensor bushing 36, a pressure sensor 37, a sensing element 38, a slotted photoelectric support 39, and a photoelectric sensor 40. The aluminum support 33 is set on the upper surface of the lower mold base plate 10. There are two light curtain supports 34, which are set on the upper surface of the aluminum support 33. There are two light curtain sensors 35, which are set on the light curtain supports 34. The sensor bushing 36 is bolted to the base connecting plate 24. The pressure sensor 37 is set inside the sensor bushing 36. The sensing element 38 is bolted to the driven wheel 31 in a set of hot and cold mold flipping components. There are two slotted photoelectric supports 39, which are set on both sides of the driven wheel 31 and bolted to the rotating shaft base plate 27. There are two photoelectric sensors 40, which are set on the slotted photoelectric supports 39.

[0040] The light curtain sensor 35 can detect objects or personnel entering the danger zone and control the mechanical equipment to stop working by sending a signal, thereby avoiding safety accidents; the pressure sensor 37 can detect the pressure generated by the output cylinder 22. Through the mark on the sensing plate 38, it cooperates with the photoelectric sensor 40 to make the driven wheel 31 rotate to the designated position and then stop working. The rotating main shaft 8 drives the cold upper mold 5 and the hot upper mold 6 to rotate to the designated position and then stops working, making the rotation of the cold and hot upper molds 6 more precise and providing a better processing effect for the clothing to be processed on the lower mold 3.

[0041] Working principle: The operator places the garment to be processed onto the lower mold 3. The flipping cylinder drives the cylinder connector 16 to rotate. The cylinder connector 16, through its rotational connection with the pin shaft, drives the flipping arm 18 to rotate. The rotation of the flipping arm 18 drives the auxiliary support flipping seat 20 and the flipping adjustment seat 21 to rotate. Since the flipping adjustment seat 21 is threadedly connected to the auxiliary support screw 14, and the auxiliary support screw is threadedly connected to the support base, the rotation of the flipping adjustment seat 21 drives the rotation of the support base, allowing the auxiliary bearing 13 on the support base to clamp the garment to be processed. After clamping, the output cylinder 22 starts working, pushing the base connecting plate 24 downward. Through the mounting bolt 25, the power of the output cylinder 22 can be effectively transmitted to the flipping base plate 4. At this time, the hot upper mold 6 below the flipping base plate 4 moves downward accordingly. The pressure sensor 37 works simultaneously. When it moves to the lower mold 3, the pressure sensor 37 sends a signal to stop the output cylinder 22 from moving downward, thus pressing the lower mold 3... The garments are hot-pressed. After hot pressing, the output cylinder 22 drives the cold upper mold 5 to reset. The flipping motor 29 starts working, and the power output of the flipping motor 29 is sent to the drive wheel 30. The drive wheel 30 drives the driven wheel 31 through the synchronous belt 32, which in turn drives the rotating main shaft 8. At the same time, the sensing plate 38 works in conjunction with the photoelectric sensor 40. The driven wheel 31 rotates to a designated position and then stops working based on the mark on the sensing plate 38. The rotation of the rotating main shaft 8 achieves the alternation of the cold upper mold 5 and the hot upper mold 6. The output cylinder 22 repeats the previous downward movement operation to cold-press the garments on the lower mold 3. After cold pressing, the output cylinder 22 resets, and the flipping cylinder works again. Through components such as the cylinder connector 16, the flipping arm 18, the auxiliary support flipping seat 20, and the flipping adjustment seat 21, the auxiliary bearing 13 is moved away from the bottom of the lower mold 3 to loosen the processed garments. The operator takes the processed garments out of the lower mold 3. The light curtain sensor 35 detects the personnel entering, and the equipment stops running.
