Description

Technical Field

[0001] The utility model relates to the technical field of plastic sheet processing, and particularly relates to a water transfer printing device for plastic sheets. Background Technique

[0002] Plastic sheets are materials widely used in fields such as construction, furniture, automotive interiors, and electronic product casings. It has the advantages of light weight, corrosion resistance, and easy processing. However, its surface is usually relatively smooth and lacks decoration. Therefore, various surface treatment technologies are needed to improve its aesthetics and functionality. The water transfer printing technology is a technology for transferring patterns to the surface of objects, especially suitable for objects with irregular or complex shapes. Through water transfer printing, colorful patterns can be formed on the surface of plastic sheets, which not only enhances the visual effect but also provides an additional protective layer, improving the wear resistance and corrosion resistance of plastic sheets.

[0003] The patent with the publication number CN216969026U discloses an automatic transfer printing device for a water transfer printing device, including a liquid storage tank. Both sides of the top of the liquid storage tank are fixedly connected with brackets. The brackets are jointly rotatably connected with a rotating shaft. One end of the rotating shaft is fixedly connected with a second rope reel. The bottom of the second rope reel is connected with a first rope reel through a belt. One side of the liquid storage tank close to the first rope reel is fixedly connected with a motor. The driving end of the motor is fixedly connected with the first rope reel. A plurality of mounting frames are fixedly connected to the middle of the rotating shaft. A plurality of placing mechanisms are rotatably connected to the middle edge of the mounting frames. In the utility model, the setting of the placing mechanism facilitates better limiting of the workpiece and better transfer printing. The setting of the return spring, connecting block, fixed groove, and spring groove in the placing mechanism facilitates better replacement of the counterweight column. The counterweight column can be adjusted according to the weight of the workpiece, which helps to save energy.

[0004] In the specific use process of the above-mentioned prior art, the counterweight column in the placing mechanism will contact the water transfer printing film first, which will cause damage to the water transfer printing film. And the workpiece is placed in the concave plate, resulting in the workpiece not being able to fully contact the water transfer printing film, and there will be a situation where some positions of the workpiece cannot be transferred with patterns. Moreover, during the water transfer printing operation, generally, the workpiece needs to enter the water tank with a film laid at an inclined angle. The above-mentioned prior art will affect the water transfer printing quality of the workpiece. In view of this, we propose a water transfer printing device for plastic sheets.

[0027] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0028] A water transfer printing device for plastic sheets, including a water tank 1, which serves as a container during the water transfer printing process, used to hold water and water transfer printing film, providing the environment required for transfer printing. At the bottom of the rear side of the water tank 1, there is a fixed convex plate 12, which is used to support and fix the lifting component 2. At the top of the fixed convex plate 12, there is a lifting component 2. The lifting component 2 includes a fixed vertical column 20 fixedly connected to the top of the fixed convex plate 12. An activity groove 200 is opened on the front side of the fixed vertical column 20, providing guidance for the sliding of the moving block 23. A vertical lead screw 21 is rotatably connected in the activity groove 200. By rotating the vertical lead screw 21, the moving block 23 is driven to move up and down. At the top of the fixed vertical column 20, there is a first motor 22 for driving the vertical lead screw 21 to rotate. The first motor 22 is powered by an external power source and is used to drive the vertical lead screw 21 to rotate, thereby controlling the lifting of the moving block 23. The outer wall of the vertical lead screw 21 is threadedly connected with a moving block 23. On the front side of the moving block 23, there is an angle adjustment component 3. By rotating the vertical lead screw 21, it moves up and down, thereby adjusting the height of the angle adjustment component 3;

[0029] The angle adjustment component 3 includes a fixed horizontal plate 30 fixedly connected to the front side of the moving block 23, which serves as the basic support structure of the angle adjustment component 3. The front side of the fixed horizontal plate 30 is rotatably connected with a U-shaped rotating block 31 through a rotating shaft 32. By connecting the fixed horizontal plate 30 and the U-shaped rotating block 31 through the rotating shaft 32, the rotation of the U-shaped rotating block 31 is realized, and the angle adjustment is achieved. A worm gear 33 is provided on the rotating shaft 32. At the bottom of the fixed horizontal plate 30, there is a U-shaped fixed block 34. Between the front and rear sides of the inner wall of the U-shaped fixed block 34, there is a worm 35 meshing and driving with the worm gear 33. The worm gear 33 is installed on the rotating shaft 32 and meshes with the worm 35. By rotating the worm 35, the rotation of the rotating shaft 32 and the U-shaped rotating block 31 is realized. At the rear side of the U-shaped fixed block 34, there is a second motor 36 for driving the worm 35 to rotate. The second motor 36 is powered by an external power source. On the front side of the U-shaped rotating block 31, there is an adsorption component 4. The second motor 36 drives the worm 35 to rotate, thereby adjusting the angle of the U-shaped rotating block 31 and realizing the adjustment of the inclination angle of the plastic sheet;

[0030] The adsorption assembly 4 includes a U-shaped plate 40 fixedly connected to the front side of the U-shaped rotating block 31. As the basic support structure of the adsorption assembly 4, a bidirectional lead screw 41 is rotatably connected between the left and right sides of the inner wall of the U-shaped plate 40. Both threaded regions of the bidirectional lead screw 41 are threadedly connected with moving rods 42. By rotating the bidirectional lead screw 41, the two moving rods 42 are driven to move left and right, thereby adjusting the distance between the two moving rods 42 to adapt to plastic plates of different lengths. The front end of the moving rod 42 is provided with a first vacuum suction cup 44. The middle of the rear side of the inner wall of the U-shaped plate 40 is provided with a fixed rod 43. The bidirectional lead screw 41 penetrates through the side surface of the fixed rod 43. The front end of the fixed rod 43 is provided with a second vacuum suction cup 45. The first vacuum suction cup 44 and the second vacuum suction cup 45 are respectively fixed to the front ends of the moving rod 42 and the fixed rod 43, and are used for adsorbing and fixing the plastic plate to be transferred. When the plastic plate moves towards the water tank 1, the plastic plate will first contact the water transfer film, and the plastic plate is inclined. During the downward movement, it can fully contact the water transfer film to ensure the water transfer quality of the plastic plate.

[0031] In this embodiment, two symmetrically arranged feet 10 are provided at the bottom of the water tank 1 for supporting the water tank 1. A drain pipe 11 with a valve is provided at the bottom of the water tank 1 and near the left side for discharging the water in the water tank 1.

[0032] Specifically, the moving block 23 is slidably connected to the movable groove 200 to provide guidance for the sliding of the moving block 23.

[0033] Further, a rectangular hole 300 is formed at the top of the fixed horizontal plate 30 and near the front end. The worm wheel 33 is located in the rectangular hole 300 to provide an installation space for the worm wheel 33.

[0034] Further, a knob 47 is rotatably connected to the right side of the U-shaped plate 40. The left end of the rotating shaft of the knob 47 is coaxially connected to the right end of the bidirectional lead screw 41. By rotating the knob 47, the rotation of the bidirectional lead screw 41 is controlled to realize the movement of the moving rod 42.

[0035] Further, a positioning rod 46 is provided between the left and right sides of the inner wall of the U-shaped plate 40 and near the front end. The moving rod 42 is slidably connected to the outside of the positioning rod 46 to provide guidance for the sliding of the moving rod 42 and improve the stability of the adsorption assembly 4.

[0036] When the water transfer printing equipment for plastic sheets in this embodiment is in use, an appropriate amount of water is injected into the water tank 1, and the water level is ensured to be moderate. Then, the water transfer printing film is laid flat on the water surface in the water tank 1, ensuring that the water transfer printing film has no wrinkles and floats flat on the water surface. According to the size of the plastic sheet, the two-way lead screw 41 is rotated and adjusted through the knob 47, so that the two moving rods 42 move to appropriate positions, ensuring that the two first vacuum suction cups 44 and the second vacuum suction cups 45 can adsorb and fix the plastic sheet. Then, the worm 35 is driven by the second motor 36, and the worm 35 drives the worm gear 33 to rotate, driving the rotating shaft 32 and the U-shaped rotating block 31 to rotate, adjusting the inclination angle of the plastic sheet, ensuring that the plastic sheet enters the water tank 1 at the best angle and is in full contact with the water transfer printing film. After adjusting the inclination angle of the plastic sheet, the first motor 22 is used to drive the vertical lead screw 21 to rotate, and the vertical lead screw 21 drives the moving block 23 to move downward, slowly moving the plastic sheet fixed on the adsorption assembly 4 towards the water tank 1, making it gradually contact the water transfer printing film, ensuring that the surface of the plastic sheet is in full contact with the water transfer printing film, so that the pattern is completely transferred to the surface of the plastic sheet. After the transfer is completed, the workpiece is lifted out of the water tank 1 through the first motor 22 and the vertical lead screw 21, and the adsorption of the first vacuum suction cup 44 and the second vacuum suction cup 45 is disconnected, and the plastic sheet that has been transferred is removed from the adsorption assembly 4.
