Description

Technical Field

[0001] This utility model belongs to the field of garment production, and specifically relates to a hot and cold press machine for pressing shoulder seams and hat brims. Background Technology

[0002] The bonding of clothing fabrics is mainly accomplished by machine hot pressing, which greatly shortens the production process. After the product is pressed at high temperature, it needs to be taken out, laid flat and placed in a ventilated place for a period of time to achieve the effect of cooling and shaping. However, due to the elastic shrinkage of clothing and the fact that the shrinkage rate of the fabric is not completely consistent, it is difficult for the product size to meet the uniform size required by the design. In addition, the adhesive melts after high temperature pressing, and the release of the pressing and natural cooling will cause its bonding strength to decrease, resulting in a lot of wrinkles on the fabric surface, or misalignment between the two fabrics that were originally bonded, resulting in a decrease in the yield rate of the product. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This utility model provides a solution to the problem that the natural cooling after release of pressure causes a decrease in the adhesive force, resulting in a large number of wrinkles on the fabric surface, or misalignment between the two originally bonded fabrics, leading to a decrease in the yield rate of the product.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-9 As shown, this utility model provides a hot and cold ironing machine for pressing shoulder seams and hat brims, used for pressing and shaping the shoulder and side seams of garments. It includes a worktable 1, a moving module 2, and an ironing mechanism 3. The top surface of the worktable 1 has two ironing stations 11. The moving module 2 is located above the ironing stations 11 and drives the ironing mechanism 3 to reciprocate between the two ironing stations 11. The ironing mechanism 3 includes a moving component 31, a lifting assembly 32, and a frame 33. One side of the moving component 31 is connected to... The mobile module 2 is driven and connected. One end of the lifting component 32 is fixedly installed with the mobile part 31, and the other end is fixedly connected with the frame 33, and is used to realize the lifting function of the frame 33. The frame 33 is provided with a rotating connector 12. The upper and lower surfaces of the rotating connector 12 are respectively provided with a hot press head 121 and a cooling head 13. Each of the two pressing stations 11 is provided with a fixed platform 14. The shape of the top surface of the fixed platform 14 corresponds to the shape of the hot press head 121 and the cooling head 13.

[0031] Furthermore, such as Figures 3-6The rotating connector 12 includes a first mounting plate 122, a second mounting plate 123, and a connecting groove 124. The first mounting plate 122 and the second mounting plate 123 are used to fix the hot press head 121 and the cooling head 13, respectively. The connecting groove 124 is used to install the pipelines of the hot press head 121 and the cooling head 13. A rotating drive member 331 and a drive wheel 332 are provided on one side of the frame 33. The drive wheel 332 rotates through the frame 33 and is fixedly connected to the rotating connector 12. The output end of the rotating drive member 331 is connected to a drive belt 333. The other end of the drive belt 333 is connected to the drive wheel 332. The hot press head 121 and the cooling head 13 are rotationally symmetrical about the axis of the drive wheel 332. Specifically, the adhesive sheet used to bond two pieces of fabric can be a TPU sheet. After the adhesive sheet is sandwiched between the two pieces of fabric, it is fixed on the fixed platform 14. The top of the fabric on the fixed platform 14 is heated by the hot press head 121, so that the adhesive sheet melts and bonds the two pieces of fabric. At this time, the adhesive sheet is in a molten state. The frame 33 is raised by the lifting component 32. The output end of the rotary drive component 331 drives the drive wheel 332 to rotate through the transmission belt 333. Preferably, the rotary drive component 331 can be a motor, so that the rotary connector 12 rotates. At this time, the cooling head 13 faces the fixed platform 14. Then, the lifting component 32 presses the top of the fabric on the fixed platform 14 and cools it, so that the molten adhesive sheet cools and sets quickly. By setting the cooling head 13 and the hot press head 121 to be rotated symmetrically, it is possible to quickly rotate 180° to switch to the cooling head 13 after the hot press head 121 melts the adhesive sheet, and quickly cool and set the adhesive sheet by pressing it with the cooling head 13, without having to adjust the position of the cooling head 13 in other directions.

[0032] Furthermore, such as Figures 5-6As shown, the cooling head 13 has a hollow structure, and the second mounting plate 123 has an inlet 1231 and an outlet 1232 communicating with the interior of the cooling head 13. The cooling head 13 includes a contact portion 131 and a sealing portion 132. The contact portion 131 has a hollow structure, and the sealing portion 132 is connected to the contact portion 131 to form a cooling cavity 130. The sealing portion 132 is connected to the second mounting plate 123 and has through holes 1233 communicating with the inlet 1231 and the outlet 1232 respectively. Specifically, when the cooling head 13 is used, the refrigerant pipes used to connect the inlet 1231 and outlet 1232 are installed in the connecting groove 124 and connected to the outside. The cold water pipes can be flexible hoses, so that when the rotating drive 331 drives the rotating connector 12 to rotate 180°, each cold water pipe remains connected and fixed to the inlet 1231 and outlet 1232, achieving smooth liquid circulation. The connecting groove 124 can be set up to organize the pipelines. The cold water can be water. The water enters the cooling chamber 130 through the cold water pipe through the inlet 1231. The water in the cooling chamber 130 flows out through the outlet 1232, realizing water circulation in the cooling chamber 130 and achieving a better cooling effect. It is worth noting that the heating temperature generated by the hot press head 121 is sufficient to melt the film. Preferably, the heating temperature generated by the hot press head 121 can melt the TPU film. The cooling temperature generated by the cooling head 13 is sufficient to solidify the film. Preferably, the cooling temperature generated by the cooling head 13 can melt the TPU film.

[0033] Furthermore, such as Figures 4-8As shown, the working ends of the hot pressing head 121 and the cooling head 13 are both concave structures, while the working ends of the fixed platform 14 are both convex structures. A negative pressure chamber 141 is provided inside the fixed platform 14, and the working end of the fixed platform 14 is provided with several negative pressure holes 142, each of which communicates with the negative pressure chamber 141. The negative pressure chamber 141 opens outward from the fixed platform 14 and communicates with an external vacuum pump. A control switch 10 and an elastic pedal 101 for pressing the control switch 10 are provided on one side of the bottom of the worktable 1. The control switch 10 is used to control the external vacuum pump. Specifically, after inserting a film between two pieces of fabric belonging to the shoulder area of ​​the garment, pressing the control switch 10 by stepping on the elastic pedal 101 causes the external vacuum pump to work in the negative pressure chamber 141 to create negative pressure, thereby allowing the fabric to be adsorbed onto the fixed platform 14 through the negative pressure hole 142. By setting the concave structure of the hot press head 121 and the cooling head 13 to engage with the convex structure of the fixed platform 14, the fabric belonging to the shoulder area of ​​the garment on the fixed platform 14 can be sewn. Other shaped structures of the hot press head 121, cooling head 13 and corresponding fixed platform 14 can also be set to sew other parts of the garment. To achieve this technical means, the fixed platform 14 can be detachably connected to the ironing station 11, and the hot press head 121 and cooling head 13 can be detachably connected by the rotating connector 12, thereby enabling processing of other parts of the garment without replacing the entire machine, reducing production costs.

[0034] Furthermore, such as Figures 1-3 as well as Figure 9As shown, the top surface of the workbench 1 is also provided with a mounting bracket 102. The mounting bracket 102 extends above the two pressing stations 11 with a hoisting part 103. The moving module 2 is disposed in the hoisting part 103. The bottom of the hoisting part 103 is provided with a linear guide 104. The moving part 31 is slidably connected to the linear guide 104 on the side away from the moving module 2. The first end 310 of the moving part 31 is drivenly connected to the moving module 2, and the second end 311 is slidably connected to the linear guide 104. The top of the frame 33 is provided with a plurality of elastic members 334. The other end of each elastic member 334 is connected to a pressure plate 34. The pressure plate 34 is connected to the output end of the lifting assembly 32. Specifically, the heat pressing mechanism 3 is suspended above the heat pressing station 11. When moving, the first end 310 of the moving part 31 is driven by the moving module 2 to move the moving part 31, and the second end 311 of the moving part 31 slides with the linear guide 104, so that the moving part 31 moves with good linearity. The lifting component 32 can be a cylinder and several guide rods set on the moving part 31. The output shaft of the cylinder and the guide rods slide through the moving part 31, and one end of the output shaft of the cylinder and the guide rods are connected to the pressure plate 34. When the frame 33 is driven down by the lifting component 32, the hot pressing head 121 or the cooling head 13 presses the top of the fabric on the fixed platform 14. During this process, the lifting component 32 drives the pressure plate 34 to move the frame 33 downward. After the hot pressing head 121 or the cooling head 13 contacts the fabric on the fixed platform 14, the lifting component 32 continuously pushes the pressure plate 34, so that the elastic element 334 between the pressure plate 34 and the frame 33 undergoes elastic deformation, so as to achieve an elastic pressing effect.

[0035] The following is a detailed explanation of the working principle of this utility model;

[0036] In use, the film is sandwiched between two pieces of fabric belonging to the shoulder area of ​​the garment and fixed to the top surface of the fixed platform 14. The moving module 2 drives the pressing mechanism 3 to move upward to the fixed platform 14, and the lifting component 32 drives the frame 33 to descend, so that the hot pressing head 121 presses against the top of the fabric on the fixed platform 14 and heats it, so that the film melts and bonds the two pieces of fabric. At this time, the film is in a molten state. The lifting component 32 raises the frame 33 and rotates the rotating connector 12 so that the cooling head 13 faces the fixed platform 14. The lifting component 32 then presses against the top of the fabric on the fixed platform 14 and cools it, so that the molten film cools and sets quickly, achieving stable bonding of the two pieces of fabric. This avoids the misalignment of the two pieces of fabric caused by directly removing the film while it is in a molten state, improving the sewing quality and increasing the yield rate.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
