Description

Technical Field

[0001] This utility model relates to the field of heat transfer printing technology, specifically a heat transfer printing system for clothing fabrics. Background Technology

[0002] Heat transfer printing is one of the textile printing methods. Apparel heat transfer printing is generally divided into heat-melt transfer printing and sublimation transfer printing. Heat-melt transfer printing is commonly used for cotton products, while sublimation transfer printing is commonly used for polyester. Current heat transfer printing methods utilize transfer printing paper and a heat transfer printing machine to transfer patterns of different styles and colors. During operation, the heating plate of the transfer printing machine is preheated. Then, the fabric is laid on the placement table and smoothed. The printed side of the transfer printing paper is then pressed tightly against the fabric. The preheated heating plate is then applied, and through the action of heat and pressure, the printed pattern is transferred onto the fabric. The dyes undergo sublimation and transfer to the fabric to form various desired patterns. In traditional heat transfer printing machines, the fabric is laid directly on the placement table. Different fabrics have different materials and thicknesses, and their elasticity varies, causing bulges and wrinkles in the printing area. When the heating plate moves down to the fabric surface, the wrinkled areas overlap, making printing difficult. At this point, it is necessary to manually press down the fabric around the placement table to prevent further wrinkling before printing can proceed, which is very inconvenient. Therefore, we propose a heat transfer printing system for clothing fabrics. Utility Model Content

The printing mechanism 4 also includes a transmission assembly 45, which includes gear 451, gear 452, synchronous pulley 453, and gear 454. The movable frame 41 has mounting slots in the center of each slot. Gear 1 451, Gear 2 452, and Gear 3 454 are rotatably connected to the center of each mounting slot. From the outside to the inside, they are gear 1 451, gear 2 452, and gear 3 454, forming a gear set. Gear 1 451 meshes with the vertically adjacent rack plate 42.

The sides of gear 1 451 and gear 2 452, located in the same mounting slot, are each equipped with a synchronous pulley 453. The diameter of the synchronous pulley 453 near the center of the placement platform 2 is smaller than the diameter of the synchronous pulley 453 away from the center of the placement platform 2.

Both synchronous pulleys 453 are connected by synchronous belt drive, providing a stable transmission effect for fixing the garment fabric. The lower end of the outer surface of the placement platform 2 is provided with grooves 3. The inside of each groove 3 is provided with vertically distributed teeth. The teeth located in the same groove 3 form a whole that meshes with the adjacent gear 3 454.

The printing mechanism 4 also includes a heating component 47, which includes a mounting block 471, a guide column 472 and a heating plate 473. The mounting block 471 is set on the mounting base 1.

The input end of the heating plate 473 is electrically connected to the output end of the microcontroller 5. The heating plate 473 is vertically adjacent to the placement table 2, providing a heating effect for the printing operation. The printing mechanism 4 also includes an electric push rod 48, which is located in the middle of the lower end of the mounting block 471. The input end of the electric push rod 48 is electrically connected to the output end of the microcontroller 5. The lower end of the telescopic end of the electric push rod 48 is fixedly connected to the middle of the upper end of the heating plate 473, providing a stable driving effect for the printing operation. The printing mechanism 4 also includes a limiting component 49, which includes a limiting post 491 and a lead screw 492. The limiting post 491 is located on the upper rear side of the moving frame 41.The lead screw 492 is threaded into the upper end of the limiting post 491. A knob is located at the upper end of the lead screw 492. The lower rear side of the heating plate 473 is fitted with the upper end of the knob to provide a limiting effect for the printing process. A printing mechanism 4 with a fixing effect is provided. Through the cooperation of the gear set and rollers 43, the garment fabric around the placement table 2 can be quickly fixed while printing, preventing bulging and wrinkling of the printed area. Simultaneously, the height of the limiting post 491 can be adjusted quickly and accurately to fix fabrics of different thicknesses.

[0024] The working principle of the heat transfer printing system for clothing fabrics provided by this utility model is as follows: During the printing process, the area of ​​the clothing fabric to be printed is placed above the placement table 2. The microcontroller 5 controls the heating plate 473 to preheat it. Then, the side of the transfer printing paper with the printed pattern is pressed tightly against the clothing fabric. After the heating plate 473 has finished preheating, the microcontroller 5 controls the electric push rod 48 to work. The telescopic end of the electric push rod 48 extends downward, moving the heating plate 473 downward. The guide column 472 provides guidance for the movement of the heating plate 473 until the heating plate 473 is in close contact with the surface of the clothing fabric. As the heating plate 473 is pressed down, the heating plate 473 and the placement table 2 form a certain clamping effect on the clothing fabric. As a result, the heating plate 473 itself emits heat, creating a high-temperature and high-pressure effect, which causes the dye in the transfer printing paper to sublimate and transfer to the clothing fabric, forming various patterns as desired. Simultaneously, as the heating plate 473 moves downward, its lower rear end contacts the top of the knob. With further downward movement, the heating plate 473 presses down on the limiting post 491 and the lead screw 492, causing them to move downward synchronously. As the limiting post 491 moves downward, the moving frame 41 also moves downward synchronously along the lower end of the outer surface of the placement platform 2. At this time, because the teeth within the same groove 3 are all meshed with the adjacent gear 454, the movement... As the frame 41 moves downward, gear 3 454 rotates outward. Because gear 2 452 meshes with gear 3 454, gear 2 452 also rotates inward. As gear 2 452 rotates, the synchronous pulley 453 near the center of the placement platform 2 also rotates. Then, through the transmission of the synchronous belt, the synchronous pulley 453 away from the center of the placement platform 2 rotates, causing gear 1 451 to rotate inward, driving the rack plate 42 to move inward. The roller 43 also moves inward. At this time, the roller 43 moves inward and downward simultaneously with the downward movement of the moving frame 41 until the outer edge of the roller 43 contacts the clothing fabric around the placement platform 2. As the roller 43 continues to move, it presses the clothing fabric inward while pulling it downward. By pressing and pulling down the fabric, the printed areas of the fabric can be prevented from bulging and wrinkling. At the same time, the spring 44, through its own elastic deformation, can keep the roller 43 in close contact with the surface of the fabric until the heating plate 473 contacts the printed area of ​​the fabric. For fabrics of different thicknesses, the knob can be turned to drive the lead screw 492 to rotate. Turning the knob clockwise will screw the lead screw 492 into the limiting post 491, and turning the knob counterclockwise will screw the lead screw 492 out of the limiting post 491. By screwing the lead screw 492 in and out, the height of the limiting post 491 is changed, thereby changing the stroke of the moving frame 41, and further changing the moving distance of the roller 43, so as to realize the pressing and fixing work of fabrics of different thicknesses.

[0025] It is worth noting that the microcontroller 5 disclosed in the above embodiments is an S7-200 microcontroller, the heating plate 473 is a YKJRB-210219 heating plate, and the electric push rod 48 is a YSW-10B electric push rod. The microcontroller 5 controls the operation of the heating plate 473 and the electric push rod 48 using methods commonly used in the prior art.
