Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer machines, in particular to a double-sided duplex upper and lower heating heat transfer machine. Background Art

[0002] Thermal transfer fabric heat press machine is a key equipment used for printing patterns on various fabrics. Its main function is to achieve high-quality and lasting printing effects. It is widely used in clothing, home fabrics and other industries. Its structure mainly includes a sturdy body, a key heating system (including heating plates and heating elements), a sophisticated control system, a transfer paper system and a pressure system. The working principle is to print the pattern on the transfer paper, and then place the transfer paper and the target fabric under the heating plate. Through the parameters set by the control system, the heating plate provides sufficient temperature to transfer the pigment, dye or ink on the transfer paper to the target fabric. This process ensures the accuracy and firmness of printing, and the characteristics of thermal transfer also enable the pattern to be better integrated into the fabric fiber, achieving a more natural and soft effect. For example, a pneumatic upper and lower heating heat transfer machine disclosed in the authorization announcement number CN208438868U includes a support arm, an upper heating plate, a lower heating plate, a base and a column vertically fixed on one side of the base, which are arranged in sequence from top to bottom; the upper heating plate and the lower heating plate are arranged opposite to each other up and down; one end of the support arm is fixedly connected to the upper end of the column; the lower heating plate is fixedly arranged on the upper end surface of the base Etc., it can use the upper heating plate alone for heating, or it can change the lower heating plate to the upper heating plate, and the upper and lower upper heating plates can be heated simultaneously to improve the hot stamping effect. However, a fixed workbench is used in this technical solution, that is, the staff needs to place the hot stamping material on the lower heating plate each time hot stamping is performed, and the finished product can be removed only after the hot stamping work is completed, so as to work in a cycle. During the operation of changing the hot stamping material, the machine downtime is relatively long, and the hot stamping points of the hot stamping material need to be constantly re-arranged and adjusted, making it difficult to achieve a continuous and uninterrupted hot stamping process, thereby limiting the improvement of production efficiency.

[0020] Prepare the preparatory parts for hot stamping on the front workbench 8, then start the hydraulic lifting unit to drive the upper heating plate 6 downward, so that the upper heating plate 6 and the lower heating plate 7 are close to each other, until the upper heating plate 6 is pressed on the upper surface of the preparatory parts to directly transfer heat, and the lower heating plate 7 is in contact with the lower surface of the front workbench 8 to achieve the purpose of indirect heating, and the two provide sufficient temperature to transfer the pigment, dye or ink on the mass transfer paper to the target fabric;

[0021] The inside of the two mesh tracks 10 are both installed with a pulley-type multi-roller feeding assembly for driving the front workbench 8 and the rear workbench 9 to move. The inside of the mesh track 10 is installed with a rotating drive unit for driving the pulley-type multi-roller feeding assembly to work. A control box 4 is installed on one side of the top of the inverted U-shaped frame 2. The surface of the control box 4 is sequentially installed with a microcomputer 401, a lower plate temperature controller 402, a main power switch 403, a start button 404, an upper plate temperature controller 405 and an emergency stop switch 406. The output end of the control box 4 is electrically connected to the input end of the hydraulic lifting unit and the pulley-type multi-roller feeding assembly;

[0022] The rotary drive unit works by driving the pulley-type multi-roller feeding assembly, which moves the rear workbench 9 to just below the upper heating plate 6, and then repeats the above-mentioned hot stamping steps;

[0023] The hydraulic lifting unit includes a hydraulic cylinder 3 installed on the top of the inverted U-shaped frame 2, and a bottom plate 5 installed at the bottom end of the piston rod of the hydraulic cylinder 3. The input end of the hydraulic cylinder 3 is electrically connected to the output end of the control box 4. A hydraulic pump station 101 is installed on one side of the bottom of the frame 1. The oil outlet end of the hydraulic pump station 101 is connected to the liquid inlet end of the hydraulic cylinder 3. The hydraulic pump station 101 provides hydraulic pressure for the hydraulic cylinder 3.

[0024] The outer walls on both sides of the bottom plate 5 are both provided with a shock absorbing structure connected to the top of the upper heating plate 6. The shock absorbing structure includes two symmetrical support edges 501 installed on the outer walls on both sides of the bottom plate 5, and a guide column 601 slidably installed inside the support edge 501.

The transmission shaft 12 drives the rubber roller 13 to rotate together, so that the front workbench 8 or the rear workbench 9 moves along the extension direction of the mesh track 10 until the front workbench 8 or the rear workbench 9 is sent to the bottom of the upper heating plate 6 to complete the hot stamping work. The double-station structure enables the thermal transfer heat printing machine to achieve continuous production.

[0028] When the embodiment of the present application is in use, the staff first prepares the preparatory parts for hot stamping on the front workbench 8, and then turns on the hydraulic lifting unit through the control box 4. The hydraulic lifting unit drives the upper heating plate 6 downward, so that the upper heating plate 6 and the lower heating plate 7 are close to each other, until the upper heating plate 6 is pressed on the upper surface of the preparatory parts to directly transfer heat, and the lower heating plate 7 is in contact with the lower surface of the front workbench 8 to achieve the purpose of indirect heating. The two provide sufficient temperature to transfer the pigment, dye or ink on the transfer paper to the target fabric. After the heat transfer is completed, the staff resets the hydraulic lifting unit through the control box 4, and pulls the target fabric and the front workbench 8 out from between the two mesh tracks 10, so that the target fabric is cooled and the pigment or dye is solidified on the fabric to ensure that the printed pattern is durable and does not fade. During the hot stamping process of the preparatory parts, the staff can Another preparation part is prepared, and the wrinkle state, hot stamping points, etc. of the preparation part are arranged.

The entire machine can achieve seamless switching between the two stages of work and preparation, reducing downtime and avoiding frequent shutdowns, material collection, and loading operations at a single workstation. Such an operation process is smoother and more efficient, thereby improving the overall efficiency of the production line.
