Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a heat transfer film printing device. Background Technology

[0002] Heat transfer printing is an emerging printing technology that originated in the late 1960s and early 1970s. Initially, heat transfer technology was mainly used for printing simple logos and patterns, such as small-batch clothing labels. With the continuous advancement of technology, heat transfer technology has gradually developed and can achieve the transfer of more complex and exquisite patterns and text. Its application fields have also continued to expand, covering multiple industries such as clothing, home furnishings, and electronic product casings.

[0003] The heat transfer film printing equipment mainly consists of an unwinding device, a heating element, a printing head, a transmission element, a rewinding device, and a control element. During operation, the unwinding device slowly unwinds the roll of heat transfer film. Driven by the transmission element, the film enters the heating area at a uniform speed. The heating element in the heating element heats the heat transfer film to a specific temperature, making the molecular structure on the surface of the film more active and enhancing its ability to adsorb ink. After heating is completed, the heat transfer film continues to move forward to the area below the printing head. The printing head, according to the preset pattern and program, precisely applies ink to the heated heat transfer film through inkjet printing, heat transfer printing, or other methods.

[0004] Currently, some heat transfer film printing equipment on the market has significant shortcomings. They lack the function of cleaning the heat transfer film before heating during the printing process. This means that dust and impurities adhering to the film surface cannot be removed before printing. Consequently, during the printing process, these contaminants easily mix with the ink and heat transfer film, causing defects, blurriness, and color deviations in the printed pattern. This severely affects the quality and aesthetics of the printed product and reduces its market competitiveness. Therefore, a heat transfer film printing device is proposed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat transfer film printing device.

[0033] Example 1

[0034] like Figures 1 to 3 As shown, this embodiment provides a heat transfer film printing equipment, including a frame 1, which serves as the main support structure. Inside the frame 1, a printing mechanism is installed. The reasonable layout of the printing mechanism ensures the smooth progress of the printing work, imparting patterns and colors to the heat transfer film. Inside the frame 1, a cleaning mechanism is also installed, which can clean the heat transfer film before printing, effectively improving the printing quality. At the same time, an adjustment mechanism is installed outside the frame 1, which ensures the stability of the tension of the heat transfer film during the printing process through precise adjustment, thereby improving the printing effect. An feeding roller 16 is installed outside the frame 1 to hold the heat transfer film to be printed, providing raw materials for the printing work. Inside the frame 1, a heating roller 20 is installed, which heats the heat transfer film to make it more suitable for printing and enhances the adhesion of the ink. An external drive mechanism is installed outside the frame 1 to provide power to the cleaning mechanism of the equipment, ensuring the normal operation of the equipment.

[0035] First, let's look at the cleaning mechanism, which includes a sliding top rod 2 and a sliding bottom rod 3. The sliding top rod 2 and sliding bottom rod 3 are externally slidably connected to the inside of the frame 1. This connection allows the sliding top rod 2 and sliding bottom rod 3 to move flexibly within the frame 1. Cleaning brushes 6 are fixedly connected to adjacent sides of the sliding top rod 2 and sliding bottom rod 3. When the sliding top rod 2 and sliding bottom rod 3 move, the cleaning brushes 6 can simultaneously clean the upper and lower surfaces of the heat transfer film. A transmission rod 4 is rotatably connected to the bottom end of the sliding top rod 2, and a transmission rod 5 is rotatably connected to the top end of the sliding bottom rod 3. Transmission rods 4 and 5 are responsible for transmitting power. The drive mechanism includes a motor 8, which is externally fixedly connected to the frame 1. The external part of the frame 1 provides power for the entire cleaning mechanism. The drive end of the motor 8 is fixedly connected to the rotating disk 7. The bottom end of the transmission rod 1 4 is rotatably connected to the inside of the rotating disk 7, and the top end of the transmission rod 2 5 is rotatably connected to the outside of the rotating disk 7. When the motor 8 starts, it drives the rotating disk 7 to rotate. The rotation of the rotating disk 7 causes the transmission rod 1 4 and the transmission rod 2 5 to drive the sliding top rod 2 and the sliding bottom rod 3 to slide back and forth inside the frame 1, so that the cleaning brush 6 can perform a comprehensive cleaning operation on the outside of the heat transfer film. This effectively avoids the problem of dust and impurities adhering to the heat transfer film during printing, which would affect the quality requirements of the heat transfer film after printing, and ensure that the printed pattern is clear and the color is uniform.

[0036] Next, let's look at the printing mechanism. The printing mechanism includes an electric guide rail 17, which is externally fixed to the outside of the frame 1, providing a moving track for the printing component 19. A slider 18 is slidably connected to the outside of the electric guide rail 17, and the printing component 19 is externally fixed to the outside of the slider 18. Driven by the electric guide rail 17 and the slider 18, the printing component 19 can precisely perform printing operations on the heat transfer film. Inside the frame 1, a printing plate 21 is provided, offering a stable printing platform for the heat transfer film. A buffer pad 22 is fixedly connected to the bottom of the printing plate 21, and its bottom is also fixedly connected to the inside of the frame 1. The buffer pad 22 acts as a buffer during the printing process, preventing damage to the heat transfer film and further ensuring printing quality. After cleaning, the heat transfer film smoothly slides into the printing plate 21 and is printed by the printing component 19, thus achieving the transfer of patterns and colors and completing the printing process.

[0037] Example 2

[0038] like Figure 1 , Figure 2 and Figure 4As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that: the adjustment mechanism includes two rotating rods 9, which are rotatably connected to the outside of the frame 1 and rotated with the frame 1 as support. The top of each of the two rotating rods 9 is rotatably connected to a control rod 10, and an adjusting roller 15 is rotatably connected to the adjacent side of the two rotating rods 9. The adjusting roller 15 is adjusted in position under the action of the rotating rods 9 and the control rods 10. The top of each of the two control rods 10 is rotatably connected to a connecting rod 11, which connects the two control rods 10 so that the two control rods 10 work together. A sliding block 12 is fixedly connected to the outside of the connecting rod 11, and a cylinder 14 is fixedly connected to the bottom of the sliding block 12. A sliding groove 13 is opened on the outside of the frame 1, and the outside of the sliding block 12 is slidably connected to the inside of the sliding groove 13. The outside of the cylinder 14 is fixedly connected to the outside of the frame 1.

[0039] During the printing process, the tension of the heat transfer film has a significant impact on the printing quality. The built-in inspection system in frame 1 can monitor the tension of the heat transfer film in real time and control the activation of cylinder 14 accordingly. Cylinder 14 pushes sliding block 12 to slide inside sliding groove 13. Sliding block 12 drives connecting rod 11 to move, which in turn causes the connecting rod 11 to rotate the control rods 10 at both ends. Ultimately, both rotating rods 9 are controlled by the control rods 10, rotating around their contact point with frame 1 as the axis of rotation. This changes the position of adjusting roller 15, thereby adjusting the tension of the heat transfer film. This controllable tension adjustment method ensures the stability of the heat transfer film during the printing process, avoiding problems such as pattern deformation and misregistration caused by uneven tension, thus ensuring the printing quality of the heat transfer film. A guide roller 23 is installed inside frame 1. The guide roller 23 guides the material during feeding, helping the operator better control the feeding roller 16 to feed the film, allowing the heat transfer film to smoothly enter the subsequent cleaning and printing stages.

[0040] Work steps

[0041] Step 1: When the processing personnel need to print on the heat transfer mold, they control the feeding roller 16 to feed the film by controlling the guide roller 23. At the same time as feeding the mold, the motor 8 can be started. The motor 8 will drive the rotating disk 7 to rotate, so that the transmission rod 1 4 and the transmission rod 2 5 will drive the sliding top rod 2 and the sliding bottom rod 3 to slide inside the frame 1, so that the cleaning brush 6 can clean the outside of the film and avoid the dust and impurities affecting the quality requirements of the heat transfer film after printing.

[0042] Step 2: After cleaning, the heat transfer film slides into the printing plate 21 and is printed by the printing component 19. During the printing process, the heat transfer film requires high tension. The inspection component built into the frame 1 controls the start of the cylinder 14 in real time. The cylinder 14 pushes the sliding block 12 to slide inside the sliding groove 13, thereby causing the connecting rod 11 to drive the control rods 10 at both ends to rotate. Finally, both rotating rods 9 are controlled by the control rods 10 and rotate around the contact point with the frame 1 as the rotation axis, thereby changing the position of the adjusting roller 15 to adjust the tension of the film. Through controllable tension adjustment, the printing quality of the heat transfer film is guaranteed.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
