Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a UV curing conveyor belt for an anti-sticking screen printing machine. Background Technology

[0002] In the screen printing industry, UV inks are widely used due to their advantages such as instant drying, vibrant colors, strong abrasion resistance, good adhesion, and environmentally friendly solvent-free evaporation. They are especially suitable for product processing fields with high requirements for drying speed, printing accuracy, and surface durability. Their curing process is triggered by ultraviolet irradiation, which induces a photochemical reaction, causing the liquid ink to rapidly cross-link into a film. This not only significantly shortens the drying time and improves production efficiency, but also reduces the environmental pollution and safety hazards caused by traditional solvent-based inks. Therefore, UV inks are widely used in various printing scenarios such as electronic products, plastic products, metal signs, glass decorations, packaging printing, and high-precision industrial parts, becoming an important part of modern efficient and green printing technology.

[0003] Traditional UV curing processes use a conveyor belt to transport substrates such as metals, plastics, and glass to a UV lamp for rapid curing of inks or coatings. However, in actual operation, inks are prone to bleeding when not fully cured, and static electricity generated during high-speed operation of the printed materials causes incompletely cured ink to adhere to the conveyor belt surface, resulting in the printed materials sticking to the conveyor belt. This problem is particularly prominent in high-temperature, high-humidity, or high-speed operating environments, which can easily lead to damage to the printed pattern, stringing, or deformation of the substrate, seriously affecting product yield.

[0004] Therefore, it is necessary to design a UV curing conveyor belt for an anti-sticking screen printing machine to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional UV curing, where ink bleeding and electrostatic adsorption easily lead to adhesion during the curing of substrates via conveyor belts, causing product damage and conveyor belt contamination, requiring frequent cleaning, and affecting production efficiency and automated operation, this utility model provides a UV curing conveyor belt for an anti-adhesion screen printing machine.

[0006] A UV curing conveyor belt for an anti-adhesion screen printing machine includes a support frame, a motor, rollers, a conveyor belt, a UV curing lamp assembly, an ion generator, and an ion bar. The motor is fixedly connected to the upper right side of the support frame, and rollers are rotatably connected to the left and right sides of the top of the support frame. The output shaft of the motor is connected to the right roller, and the conveyor belt is installed between the two rollers. The UV curing lamp assembly is installed in the middle of the top of the support frame, and the ion generator is installed on the upper right side of the support frame. An ion bar is provided on the bottom right side of the support frame. The ion bar is located at the bottom of the feed end of the conveyor belt and is electrically connected to the ion generator. The ion bar has multiple air outlets, each of which is aligned with the lower surface of the conveyor belt.

[0007] Optionally, the conveyor belt surface is made of Teflon material.

[0008] Optionally, it also includes a cooling frame, an air supply pipe and an air pump. The cooling frame is installed on the bottom right side of the support frame. The cooling frame is located below the conveyor belt. The bottom of the cooling frame is connected to and communicates with the air supply pipe, and the air supply pipe is equipped with an air pump.

[0009] Optionally, it also includes a fixed frame, a screw, a handwheel, and a movable frame. The fixed frame is installed on the bottom left side of the support frame, the screw is threadedly connected to the middle of the fixed frame, the right end of the screw is provided with a handwheel, the left end of the screw is fixedly connected to the movable frame, the upper right side of the movable frame is rotatably connected to the left side of the roller shaft, and the movable frame is slidably connected to the support frame.

[0010] Optionally, it also includes mounting blocks, connecting rods, springs, rollers, and anti-slip rubber sleeves. Mounting blocks are symmetrically installed on both sides of the outer wall of the support frame. A connecting rod is provided between each pair of symmetrical mounting blocks. A spring is sleeved between each mounting block and the corresponding connecting rod. Both ends of the two connecting rods extend upward to above the conveyor belt. Rollers are provided at both ends of the two connecting rods. Anti-slip rubber sleeves are sleeved on the surface of each roller, and the anti-slip rubber sleeves slide in contact with the surface of the conveyor belt.

[0011] Optionally, the anti-slip rubber sleeve is made of silicone.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets up an ion air bar that is electrically connected to the ion generator and is located at the bottom of the feed end of the conveyor belt. Its multiple air outlets are aligned with the surface of the conveyor belt to release ion air to neutralize the static electricity on the lower surface of the printed matter. This effectively reduces the phenomenon of dust adsorption due to static electricity or the sticking of printed matter to the conveyor belt, and improves printing quality and operational stability.

[0013] 2. This utility model, by setting up a cooling frame, an air supply pipe and an air pump, uses an air pump to drive air through the air supply pipe into the cooling frame and blow it upwards, thereby achieving the effect of forced air cooling of the bottom of the conveyor belt, reducing the overall temperature of the conveyor belt and printed materials, preventing the ink from softening and becoming sticky or the substrate from deforming under high temperature conditions, and ensuring the reliability of the curing process.

[0014] 3. This utility model uses a combination of a fixed frame, a screw, a handwheel, and a movable frame. The movable frame is slidably connected to the support frame and drives the left roller to move, thereby adjusting the tension of the conveyor belt. This solves the problem of belt loosening caused by long-term operation, ensures smooth transmission without slippage, and extends the service life of the conveyor belt.

[0015] 4. This utility model uses the cooperation of connecting rods, springs, rollers and anti-slip rubber sleeves. The rollers at both ends of the two connecting rods are covered with anti-slip rubber sleeves made of silicone material, which slide in contact with the surface of the conveyor belt under the action of spring force, so as to apply a moderate clamping force to the printed materials, effectively preventing them from warping, shifting or jumping during high-speed transmission, and improving the transmission stability and positioning accuracy of the printed materials.

Detailed Implementation

[0023] Example: A UV curing conveyor belt for an anti-blocking screen printing machine, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a support frame 1, a motor 2, rollers 3, a conveyor belt 4, a UV curing lamp assembly 5, an ion generator 6, and an ion air bar 7. The motor 2 is bolted to the upper right side of the front of the support frame 1. Rollers 3 are rotatably connected to the left and right sides of the top of the support frame 1. The output shaft of the motor 2 is connected to the right roller 3. The conveyor belt 4 is installed between the two rollers 3. The surface of the conveyor belt 4 is made of Teflon material. The UV curing lamp assembly 5 is installed in the top center of the support frame 1. The ion generator 6 is installed on the upper right side of the front of the support frame 1. The ion air bar 7 is located at the bottom right side of the bottom of the support frame 1. The ion air bar 7 is located at the bottom of the feed end of the conveyor belt 4 and is electrically connected to the ion generator 6. The ion air bar 7 has multiple air outlets, each of which is aligned with the lower surface of the conveyor belt 4.

[0024] When this device is needed, first, install the UV curing conveyor belt of the anti-sticking screen printing machine in the screen printing production line, and ensure that the support frame 1 is firmly fixed on the equipment frame to provide reliable support for the entire transmission and curing system. Start the motor 2, and its output shaft drives the right roller 3 to rotate. Since the conveyor belt 4 is sleeved between the two rollers 3, the right roller 3 acts as the active roller to drive the conveyor belt 4 to run in a cycle, and the left roller 3 acts as the driven roller to rotate in coordination, so as to realize the smooth transmission of the printed materials.

[0025] The surface of conveyor belt 4 is made of Teflon material, which has extremely low surface energy and excellent anti-stick properties. It can effectively prevent ink or coating that has not been fully cured after printing from adhering to the surface of the belt during the conveying process, fundamentally avoiding secondary pollution and adhesion problems caused by ink residue. During the operation of conveyor belt 4, the printed materials enter the UV curing area with it. At this time, the UV curing lamp group 5 is activated to irradiate the surface of the printed materials with high-intensity ultraviolet light, which promotes the rapid cross-linking and curing of ink, shortens the drying time, and improves production efficiency.

[0026] To prevent printed materials from attracting dust from the air or sticking to other surfaces due to static electricity before entering the curing zone, the ion bar 7 is equipped with multiple air outlets, each of which is aligned with the surface of the conveyor belt 4. During operation, it releases positive and negative ions to neutralize the static charge on the lower surface of the printed materials, eliminate the static adsorption effect, and ensure that the printed materials remain clean, do not shift, and do not stick during the conveying process.

[0027] like Figure 1 and Figure 3 As shown, it also includes a cooling frame 8, an air supply pipe 9, and an air pump 10. The cooling frame 8 is installed on the bottom right side of the support frame 1. The cooling frame 8 is located below the conveyor belt 4. The bottom of the cooling frame 8 is connected to and communicates with the air supply pipe 9. The air pump 10 is installed on the air supply pipe 9.

[0028] To further prevent the material from softening and sticking due to high-temperature curing, the device is also equipped with a cooling system. When the air pump 10 is started, outside air is sent into the cooling frame 8 through the air supply pipe 9 and blown upward from the top of it to force air cooling of the bottom of the conveyor belt 4, effectively reducing the overall temperature of the conveyor belt 4 and the printed matter, and avoiding ink sticking or substrate deformation due to local overheating.

[0029] like Figure 4 As shown, it also includes a fixed frame 11, a screw 12, a handwheel 13, and a movable frame 14. The fixed frame 11 is installed on the bottom left side of the support frame 1. The screw 12 is threadedly connected to the middle of the fixed frame 11. The handwheel 13 is provided at the right end of the screw 12. The movable frame 14 is installed on the left end of the screw 12 by bolts. The upper right side of the movable frame 14 is rotatably connected to the left side of the roller shaft 3. The movable frame 14 is slidably connected to the support frame 1.

[0030] During long-term operation of the equipment, the conveyor belt 4 may become loose, affecting the transmission stability. To address this, by rotating the handwheel 13 to drive the screw 12 to rotate, the moving frame 14 can be moved left and right, thereby adjusting the position of the left roller 3 and achieving precise control of the tension of the conveyor belt 4, ensuring smooth operation.

[0031] like Figure 5 and Figure 6 As shown, it also includes mounting blocks 15, connecting rods 16, springs 17, rollers 18, and anti-slip rubber sleeves 19. Mounting blocks 15 are symmetrically installed on both sides of the outer wall of the support frame 1. A connecting rod 16 is provided between each pair of symmetrical mounting blocks 15. A spring 17 is sleeved between each mounting block 15 and the corresponding connecting rod 16. Both ends of the two connecting rods 16 extend upward to above the conveyor belt 4. Rollers 18 are provided at both ends of the two connecting rods 16. Anti-slip rubber sleeves 19 are sleeved on the surface of each roller 18. The anti-slip rubber sleeves 19 slide in contact with the surface of the conveyor belt 4. The anti-slip rubber sleeves 19 are made of silicone material.

[0032] In addition, to prevent the printed materials from warping, shifting or jumping during high-speed transport, the device is also equipped with an anti-slip pressing mechanism above the conveyor belt 4. The anti-slip rubber sleeve 19 is made of silicone material, which has good elasticity and friction performance. Under the action of the spring 17, the anti-slip rubber sleeve 19 slides in contact with the surface of the conveyor belt 4, applying appropriate pressure to the printed materials, playing a guiding, flattening and anti-slip role, ensuring that it passes stably through the UV curing zone.
