Description

Technical Field

[0001] This utility model relates to the field of screen printing plate exposure machine technology, specifically a new type of environmentally friendly screen printing plate exposure machine. Background Technology

[0002] In the printing industry, screen printing plate-making machines are an important piece of equipment, mainly used to transfer design patterns onto a screen through exposure, thereby completing the plate-making process. Traditional plate-making machines usually use ultraviolet lamps as light sources, utilizing their high-energy light to cause a chemical reaction in the photosensitive emulsion, forming the desired printing pattern.

[0003] However, existing exposure machines have many flaws in their lamp replacement design. On the one hand, the lamps are often installed in concealed locations with limited space, making it difficult for operators to directly access them. Special tools or complex techniques are required, increasing the difficulty and time required, leading to increased downtime and impacting production schedules. On the other hand, some exposure machines use unscientific lamp fixing methods, often employing complex connection structures such as multiple screws or special clip designs. Replacing lamps requires disassembling multiple parts, making the process cumbersome and increasing the risk of damage to the lamps or other components during disassembly and installation, thus increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a novel environmentally friendly screen printing plate-making machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly screen printing plate exposure machine, including a housing, a light-transmitting panel on the upper surface of the housing, a top cover hinged to the top of the housing, a lamp tube and a disassembly mechanism inside the housing, the disassembly mechanism including a mounting base and a slide base located on both sides of the lamp tube and fixedly installed on both sides of the inner wall of the housing, the mounting base having two symmetrically arranged first sliding grooves, a first slider slidably connected in the first sliding groove, a first spring fixedly connected to the side of the two first sliders away from each other, an adjusting plate connected to the other end of the two first springs, the adjusting plate being slidably connected to the first sliding groove, the adjusting plate being rotatably connected to a threaded rod, the threaded rod passing through to the outside of the mounting base and threadedly connected to the mounting base, and C-shaped clamps symmetrically installed at the ends of the two first sliders away from the mounting base.

[0006] Furthermore, the slide block is provided with a second slide groove, and a second slider is slidably connected in the second slide groove. A telescopic rod is connected between the side of the second slider away from the lamp tube and the inner wall of the second slide groove, and the telescopic rod is fitted with a second spring.

[0007] Furthermore, a connector is installed on the side of the second slider away from the slide block. A positioning hole is provided on the side of the connector near the lamp tube. An installation component is installed at one end of the lamp tube. The installation component is connected to a pin. The pin is inserted into the positioning hole. An adjusting bolt penetrating the slide block is installed on the side of the slide block near the lamp tube. There are two adjusting bolts. A connecting block is fixedly connected to the adjusting bolt. An L-shaped clamp is installed on the end of the connecting block away from the adjusting bolt. The opposite sides of the two L-shaped clamps are in contact with the outer wall of the installation component.

[0008] Furthermore, the inner wall of the C-shaped clamp is attached to the outer wall of one end of the lamp tube, and several connecting rods are installed on the upper surface of the lower C-shaped clamp, while the lower surface of the upper C-shaped clamp has grooves that match the connecting rods.

[0009] Furthermore, a gasket is installed on the side of the C-shaped clamp that is in contact with the lamp tube, a pull ring is installed on the outer wall of the C-shaped clamp, and a rotating handle is installed on the end of the threaded rod located outside the mounting base.

[0010] Furthermore, doors are hinged to both the front and back sides of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adopts a detachable structure design for the lamp tube, and achieves quick installation and disassembly through the simple operation of the threaded rod and adjusting bolt. This reduces waste and energy loss caused by lamp tube replacement. The convenient maintenance process reduces equipment downtime, improves production efficiency, and reduces unnecessary resource waste. The active clamping of the C-shaped clamp and the elastic support of the slide ensure stable operation of the lamp tube, reduces lamp tube damage caused by vibration or impact, extends lamp tube life, and reduces replacement frequency.

[0013] 2. This utility model uses a flexible gasket design on the inner wall of the C-shaped clamp to buffer the hard impact of the clamping force on the surface of the lamp tube, avoiding scratches and damage, reducing material waste caused by lamp tube damage. At the same time, the gasket compensates for the difference in the outer diameter of the lamp tube, ensuring tight and uniform clamping, improving exposure quality, and reducing the defect rate. The pull ring on the outer wall of the C-shaped clamp provides a point of force for manually adjusting the position of the C-shaped clamp, making it convenient for operators to directly pull the C-shaped clamp. A rotating handle is installed at one end of the threaded rod outside the mounting base. By rotating the rotating handle, the clamping and releasing operations of the lamp tube can be easily realized. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] See Figure 1 , Figure 2 and Figure 3As shown, a novel environmentally friendly screen printing plate-making machine includes a housing 1. A light-transmitting panel 6 is provided on the upper surface of the housing 1. A top cover 7 is hinged to the top of the housing 1. A lamp tube 4 and a disassembly mechanism are provided inside the housing 1. The disassembly mechanism includes a mounting base 2 and a slide base 3 located on both sides of the lamp tube 4 and fixedly installed on both sides of the inner wall of the housing 1. The mounting base 2 has two symmetrically arranged first slide grooves 23. A first slider 10 is slidably connected in the first slide groove 23. A first spring 9 is fixedly connected to the side of the two first sliders 10 that is far away from each other. An adjusting plate 8 is connected to the other end of the two first springs 9. The adjusting plate 8 is slidably connected to the first slide groove 23. A threaded rod 25 is rotatably connected to the adjusting plate 8. The threaded rod 25 passes through to the outside of the mounting base 2 and is threadedly connected to the mounting base 2. C-shaped clamps 11 are symmetrically installed on the ends of the two first sliders 10 that are far away from the mounting base 2.

[0023] In the specific implementation process, the light-transmitting panel 6 is the component in the screen printing exposure machine that directly contacts the exposure process. The screen printing plate to be exposed needs to be placed flat on its surface. The screen printing plate is coated with photosensitive emulsion. When ultraviolet rays emitted by the lamp tube 4 pass through the light-transmitting panel 6, the photosensitive emulsion undergoes a photochemical reaction, thereby completing the plate making. When the lamp tube 4 needs to be installed, the lamp tube 4 is first placed between the two mounting seats 2 and corresponding to the position of the C-shaped clamp 11. Then, the threaded rod 25 is rotated. Since the threaded rod 25 is threadedly connected to the mounting seat 2 and rotatably connected to the adjusting plate 8, as the threaded rod 25 rotates, the adjusting plate 8 will slide along the first slide groove 23. When the adjusting plate 8 slides, it will compress or stretch the first spring 9. The elastic force of the first spring 9 acts on the first slider 10, causing the first slider 10 to slide in the first slide groove 23, thereby driving the C-shaped clamp 11 to move. By adjusting the threaded rods 25 on the two mounting bases 2, the C-shaped clamps 11 on both sides are brought closer together until the lamp tube 4 is stably clamped between the C-shaped clamps 11, thus completing the installation of the lamp tube 4. When it is necessary to remove the lamp tube 4, the threaded rods 25 are rotated in the opposite direction. Under the elastic force of the first spring 9, the adjusting plate 8 slides in the opposite direction along the first slide groove 23, which drives the first slider 10 and the C-shaped clamps 11 away from the lamp tube 4, thereby causing the lamp tube 4 to lose the clamping force and easily remove the lamp tube 4 from the C-shaped clamps 11, thus completing the removal of the lamp tube 4.

[0024] See Figure 1 and Figure 3As shown, the slide block 3 has a second slide groove 26, and a second slider 16 is slidably connected in the second slide groove 26. A telescopic rod 22 is connected between the side of the second slider 16 away from the lamp tube 4 and the inner wall of the second slide groove 26. A second spring 21 is sleeved on the telescopic rod 22. In the specific implementation process, the second slider 16 can slide within the second slide groove 26. Through the elastic connection of the telescopic rod 22 and the second spring 21, the slide 3 can adapt to the installation position or slight deformation of the lamp tube 4. When the lamp tube 4 undergoes a small displacement due to thermal expansion and contraction or external force, the second slider 16 can slide to adjust, avoiding damage to the lamp tube 4 due to rigid fixation. The second spring 21 provides a buffering effect, reducing the stress caused by vibration or impact during the installation or operation of the lamp tube 4, and extending the life of the lamp tube 4. The mounting base 2 actively clamps the lamp tube 4 through the C-shaped clamp 11, while the slide 3 provides passive adaptation through the elastic support of the second slider 16 and the spring. The combination of the two ensures that the lamp tube 4 is stably fixed in both the axial and radial directions, while allowing for minor adjustments. The telescopic rod 22 limits the sliding range of the second slider 16, preventing the lamp tube 4 from deviating from the center position due to excessive sliding, and ensuring exposure uniformity.

[0025] See Figure 3 , Figure 4 and Figure 5 As shown, a connector 17 is installed on the side of the second slider 16 away from the slide block 3. A positioning hole 27 is opened on the side of the connector 17 near the lamp tube 4. A mounting part 15 is installed on one end of the lamp tube 4. A pin 28 is connected to the mounting part 15. The pin 28 is slidably connected to the positioning hole 27. An adjusting bolt 20 is installed on the side of the slide block 3 near the lamp tube 4, which passes through the slide block 3. There are two adjusting bolts 20. A connecting block 19 is fixedly connected to the adjusting bolt 20. An L-shaped clamp 18 is installed on the end of the connecting block 19 away from the adjusting bolt 20. The opposite sides of the two L-shaped clamps 18 are in contact with the outer wall of the mounting part 15. In the specific implementation process, the position of the lamp tube 4 is initially positioned by sliding the positioning hole 27 on the plug tube 17 with the pin 28 on the mounting part 15. By rotating the adjusting bolt 20, the position and clamping force of the L-shaped clamp 18 are adjusted so that the L-shaped clamp 18 is tightly attached to the outer wall of the mounting part 15, thereby fixing the lamp tube 4. This not only improves the stability and accuracy of the lamp tube 4 installation, but also facilitates the disassembly and replacement of the lamp tube 4.

[0026] It should be noted that the slide 3 has a threaded groove, which is threadedly connected to the adjusting bolt 20. A certain gap is left between the connecting block 19 and the slide 3 to ensure that the connecting block 19 will not get stuck when it rotates and moves along the thread direction. When the L-shaped clamp 18 is just in contact with the mounting part 15, the connecting block 19 is just in contact with the slide 3. The plug tube 17 is connected to the power cord. When the pin 28 is inserted into the positioning hole 27, the lamp tube 4 can be powered on.

[0027] See Figure 3As shown, the inner wall of the C-shaped clamp 11 is in contact with the outer wall of one end of the lamp tube 4. Several connecting rods 13 are mounted on the upper surface of the lower C-shaped clamp 11, and grooves matching the connecting rods 13 are formed on the lower surface of the upper C-shaped clamp 11. In practice, these connecting rods 13 not only strengthen the connection between the two C-shaped clamps 11 but also help maintain their relative positions, making the clamping more stable. The grooves on the other C-shaped clamp 11, matching the connecting rods 13, allow the connecting rods 13 to be easily inserted and fixed, further enhancing the clamping effect of the C-shaped clamp 11 on the lamp tube 4.

[0028] See Figure 1 and Figure 3 As shown, a gasket 14 is installed on one side of the C-shaped clamp 11 that is in contact with the lamp tube 4. A pull ring 12 is installed on the outer wall of the C-shaped clamp 11. A rotating handle 24 is installed on the end of the threaded rod 25 located outside the mounting base 2. Doors 5 are hinged to both the front and back of the housing 1. In practice, the doors 5 facilitate the installation or removal of the lamp tube 4 by the operator. The gasket 14 is made of a flexible material such as rubber or silicone, which can buffer the hard contact between the C-shaped clamp 11 and the lamp tube 4, preventing damage to the surface of the lamp tube 4 due to excessive clamping force. The gasket 14 increases friction, preventing the lamp tube 4 from loosening due to vibration during operation. It can also compensate for slight differences in the outer diameter of the lamp tube 4, ensuring a tighter and more uniform clamping. When installing the lamp tube 4, the C-shaped clamp 11 directly contacts the lamp tube 4 through the gasket 14. The elastic deformation of the pad 14 ensures that the clamping force is evenly distributed. When removing the lamp tube 4, the pad 14 separates from the C-shaped clamp 11, which will not cause scratches on the surface of the lamp tube 4. When it is necessary to manually adjust the position of the C-shaped clamp 11, the pull ring 12 provides a point of force, making it easy for the operator to pull the C-shaped clamp 11 directly. When installing the lamp tube 4, rotate the handle 24 clockwise to move the adjusting plate 8 through the threaded transmission, thereby pushing the C-shaped clamp 11 to clamp the lamp tube 4. When removing the lamp tube 4, rotate the handle 24 counterclockwise to release the clamping force.

[0029] Working principle:

[0030] Step 1: During installation, place the lamp tube 4 between the two mounting bases 2, so that the pin 28 on the mounting piece 15 at one end of the lamp tube 4 is inserted into the positioning hole 27 of the insertion sleeve 17 on the slide block 3 to complete the initial positioning of the lamp tube 4. Rotate the rotating handle 24 on the mounting base 2 clockwise to drive the threaded rod 25 to rotate. Since the threaded rod 25 is threadedly connected to the mounting base 2 and rotatably connected to the adjusting plate 8, the adjusting plate 8 will slide along the first slide groove 23, compressing the first spring 9. The elastic force of the first spring 9 acts on the first slider 10, causing the first slider 10 to slide in the first slide groove 23, driving the C-shaped clamping plate 11 to move. By adjusting the threaded rods 25 on the two mounting bases 2, the C-shaped clamping plates 11 on both sides are brought closer to each other until the lamp tube 4 is stably clamped between the C-shaped clamping plates 11. At this time, the connecting rod 13 on the lower C-shaped clamp 11 is inserted into the groove of the upper C-shaped clamp 11 to enhance the clamping effect. The C-shaped clamp 11 contacts the lamp tube 4 through the gasket 14. The gasket 14 can buffer the hard contact, increase friction, and compensate for the difference in outer diameter to ensure tight and uniform clamping. The second slider 16 on the slide block 3 can slide in the second slide groove 26. Through the elastic connection of the telescopic rod 22 and the second spring 21, the slide block 3 can adapt to the installation position or slight deformation of the lamp tube 4. When the lamp tube 4 expands or contracts due to heat or cold, When a small displacement occurs due to external force, the second slider 16 can be slidably adjusted to prevent damage to the lamp tube 4 due to rigid fixation. The second spring 21 provides a buffering effect, reducing the stress on the lamp tube 4 caused by vibration or impact during installation or operation. Rotating the adjusting bolt 20 on the rotating slide 3, since the adjusting bolt 20 is threadedly connected to the slide 3, the adjusting bolt 20 will drive the connecting block 19 to move, which in turn drives the L-shaped clamp 18 to move, so that the L-shaped clamp 18 fits tightly against the outer wall of the mounting part 15, thereby further fixing the lamp tube 4. When the L-shaped clamp 18 is just in contact with the mounting part 15, the connecting block 19 is just in contact with the slide 3. At this time, the pin 28 is inserted into the positioning hole 27, and the lamp tube 4 can be powered.

[0031] Step 2: During disassembly, rotate the rotating handle 24 on the mounting base 2 counterclockwise, causing the threaded rod 25 to rotate in the opposite direction. Under the elastic force of the first spring 9, the adjusting plate 8 slides in the opposite direction along the first slide groove 23, causing the first slider 10 and the C-shaped clamp 11 to move away from the lamp tube 4, so that the lamp tube 4 loses the clamping force in the axial direction. Rotate the adjusting bolt 20 on the slide block 3 counterclockwise, so that the L-shaped clamp 18 moves away from the mounting part 15, loosening the fixation on the lamp tube 4. Due to the elastic support of the slide block 3, the lamp tube 4 can also be easily removed in the radial direction. The operator can remove the lamp tube 4 from the C-shaped clamp 11 to complete the disassembly of the lamp tube 4.
