[0041] The film transmission assembly 200 and the pressing machine 300 are both disposed below the surface of the support portion 510 , and the horizontal movement directions of the film transmission assembly 200 and the pressing machine 300 are directly opposite to the pressing portion 520 ;

[0042] The film transmission assembly 200 is used to transmit the hot melt film 220 , and the hot melt film 220 is arranged between the pressing machine 300 and the laminating part 520 .

[0043] That is to say, the support platform 500 in the present application has the support part 510 and the pressing part 520, and uses a part of the transmission roller in the fabric transmission assembly 100, so that the target fabric 600 can be turned during the transmission process. At the same time, combined with the arrangement that the pressing part 520 is arranged below the surface of the support part 510, when the target fabric 600 is pressed under the support part 510, in some actual situations, the pressing process is performed when the target fabric 600 is in a vertical state. By using the vertical state, the dust layer and impurities on the target fabric 600 move downward under the action of gravity, thereby changing the vertical pressing method in the prior art, reducing the dust layer and impurities adhering to the pressing surface.

[0044] In this example, the hot-melt film 220 can adopt the hot-melt adhesive film in the prior art. The hot-melt adhesive film is a hot-melt adhesive product that is not sticky at room temperature but is sticky on both sides at high temperature. When in use, just place the hot-melt adhesive film in the middle of the material to be bonded, and then use a pressing device (such as an iron, a flat-plate pressing machine, a roller laminating machine, etc.) to heat and iron it, so that the hot-melt adhesive film can be melted and bonded to the material. The hot-melt adhesive film is suitable for bonding a variety of materials, such as cloth, leather, and plates. It should be noted that the hot-melt adhesive film is placed between the ironing plate and the cloth to iron out colored patterns on the cloth. The ironing plate is the working end surface with patterns on the pressing machine 300.

[0045] To further understand the present case, in some preferred embodiments, a movable cavity 530 and a shell 540 slidably connected to the movable cavity 530 are further provided in the support platform 500. The movable cavity 530 and the shell 540 are both arranged below the surface of the support portion 510. The film transmission assembly 200 is arranged in the shell 540. The pressing machine 300 is slidably connected to the shell 540. It should be noted that the shell 540 is an open rectangular frame, and the shell 540 occupies 1 / 2 of the total volume of the movable cavity 530. The shell 540 is specifically slidably connected to the front end of the movable cavity 530.

[0046] To facilitate driving the pressing machine 300 and the film transmission assembly 200 to perform horizontal reciprocating movement, in some preferred embodiments, the driving assembly 400 includes at least one first screw-connected sleeve 410, at least one second screw-connected sleeve 420, a transmission member 430 connected between the first screw-connected sleeve 410 and the second screw-connected sleeve 420, and a driving member 440 connected to the first screw-connected sleeve 410 or the second screw-connected sleeve 420, one of the first screw-connected sleeve 410 and the second screw-connected sleeve 420 is connected to the shell 540, and the other is connected to the pressing machine 300, wherein the first screw-connected sleeve 410 and the second screw-connected sleeve 420 have different thread pitches, so that when the driving member 440 is running, the first screw-connected sleeve 410 and the second screw-connected sleeve 420 are driven by the transmission member 430 to rotate synchronously to drive the shell 540 and the pressing machine 300 to perform horizontal reciprocating movement.

[0047] It should be noted that the transmission member 430 can be composed of a driving gear, a driven gear, and a toothed chain. Specifically, the driving gear can be sleeved on the second screw sleeve 420, and the driven gear can be sleeved on the first screw sleeve 410, and the driving member 440 can be connected to the second screw sleeve 420. When the driving member 440 drives the second screw sleeve 420 to rotate, the second screw sleeve 420 and the first screw sleeve 410 can rotate in the same direction and at the same speed by using the setting of the transmission member 430. Through the interaction between the first screw sleeve 410 and the second screw sleeve 420, the pressing machine 300 and the film transmission assembly 200 can be reciprocated horizontally. It should be noted that the pitches of the first screw sleeve 410 and the second screw sleeve 420 are different, so that when the pressing machine 300 and the film transmission assembly 200 are driven to move, the moving speeds of the pressing machine 300 and the film transmission assembly 200 are different.

[0048] In addition, it should be noted that the driving member 440 may be a servo motor.

[0049] To further understand the present invention, one end of the first screw-connected sleeve rod 410 is rotatably connected to the side wall of the active cavity 530, and the other end is connected to the housing 540. One end of the second screw-connected sleeve rod 420 is rotatably connected to the side wall of the active cavity 530, and the other end is connected to the pressing machine 300. The thread pitch of the first screw-connected sleeve rod 410 is smaller than the thread pitch of the second screw-connected sleeve rod 420. Specifically, the first screw-connected sleeve rod 410 includes a first screw rod 411 and a screw threadedly connected to the first screw rod 411. The first sleeve rod 412 is connected to the shell body 540, and the end of the first screw rod 411 away from the first sleeve rod 412 is rotatably connected to the side wall of the movable cavity 530. The second threaded sleeve rod 420 includes a second screw rod 421 and a second sleeve rod 422 threadedly connected to the second screw rod 421. The second sleeve rod 422 is connected to the pressing machine 300, wherein the end of the second screw rod 421 away from the second sleeve rod 422 is rotatably connected to the side wall of the movable cavity 530.

[0050] Please note that Figure 6 As shown, the driving gear and the driven gear shown in the transmission member 430 can be respectively sleeved on the first screw 411 and the second screw 421, and the first screw 411 and the second screw 421 can be rotated synchronously and in the same direction by using a toothed chain. When the first screw 411 rotates, the first sleeve rod 412 drives the housing 540 to move, and the movement of the housing 540 is used to drive the film transmission component 200 to move, so that the hot melt film 220 can be attached to a part of the target fabric 600. At the same time, when the second screw 421 rotates, the second sleeve rod 422 drives the pressing machine 300 to move, and the high pressure of the pressing machine 300 is used to move the film transmission component 200. The hot-melt film 220 is melted at a temperature, and at the same time, a pattern is pressed on the target fabric 600. It should be noted that since the pitch of the first screw sleeve 410 is smaller than the pitch of the second screw sleeve 420, there will be a certain interval between the hot-melt film 220 and the pressing machine 300 during the initial movement, which prevents the hot-melt film 220 from being scalded by the high temperature of the pressing machine 300 when it is not in contact with the target fabric 600. As the first screw sleeve 410 and the second screw sleeve 420 continue to operate, when the hot-melt film 220 is in contact with the target fabric 600, the pressing machine 300 just fits onto the surface of the target fabric 600, thereby completing the pressing process.

[0051] It should be noted that the film transmission assembly 200 includes a plurality of film transmission rollers 210, at least two of the plurality of film transmission rollers 210 are respectively used to transport the hot melt film 220 and to roll up the hot melt film 220, and the other two film transmission rollers 210 are both used to transmit the hot melt film 220, wherein the hot melt film 220 is arranged flush with the edge of the shell 540, and each film transmission roller 210 is rotatably connected to the shell 540.

[0052] In some preferred embodiments, servo motors can be arranged on the film conveying roller 210 and the cloth conveying roller 110, and the servo motors can provide power output to the target cloth 600 and the hot-melt film 220 respectively. The pressing device shown in the present application can also be arranged with a PLC controller, and the servo motor and the driving component 440 can be intelligently controlled by the PLC controller, and the servo motor has the characteristics of forward and reverse rotation.

At the same time, combined with the arrangement that the pressing part 520 is arranged below the surface of the support part 510, when the target fabric 600 is pressed under the support part 510, in some actual situations, the pressing process is performed when the target fabric 600 is in a vertical state. By using the vertical state, the dust layer and impurities on the target fabric 600 move downward under the action of gravity, thereby changing the vertical pressing method in the prior art and reducing The probability of dust layer and impurities adhering to the pressing machine 300, and when the target fabric 600 is pressed, the film transmission component 200 and the pressing machine 300 are both arranged under the surface of the support part 510 in the present application, and the horizontal movement direction of the film transmission component 200 and the pressing machine 300 is opposite to the laminating part 520, and the hot melt film 220 is arranged between the pressing machine 300 and the laminating part 520, so that the hot melt film 220 is blocked between the pressing machine 300 and the target fabric 600, thereby preventing dust and impurities from adhering to the surface of the pressing machine 300, thereby solving the technical problem in the prior art that dust and impurities adhere to the surface of the ironing plate, resulting in impurities in the pattern and affecting the product yield.
