Description
Technical Field
[0001] The utility model belongs to the technical field of screen printing, and specifically relates to a multi-color screen printing process equipment. Background Art
[0002] In the field of modern printing technology, screen printing occupies a key position among many printing methods due to its unique advantages. Multi-color screen printing can produce a rich variety of colors and complex patterns, and is widely used in various industries such as electronics, packaging, and textiles.
[0003] However, traditional multi-color screen printing equipment still faces some pressing challenges in practical applications. In the two key operations of ink return and scraping, complex electrical drive systems are often required to control the retraction and extension of the ink return plate and scraper, respectively.
[0004] On the one hand, achieving precise retraction and expansion of the ink return plate and scraper requires high-precision sensors, controllers, drive motors, and other electrical components. This not only significantly increases the manufacturing cost of the equipment, but also makes these electrical components prone to failure during long-term operation, resulting in high maintenance and repair costs.
[0005] On the other hand, the complex electrical drive system makes the operation and commissioning of the equipment cumbersome. For operators, mastering the equipment's operating parameters and adjustment methods requires high technical skills and extensive experience, which to some extent limits the widespread application of the equipment and the improvement of production efficiency.
[0006] In addition, the stability and reliability of electrical components may be affected in some harsh working environments, such as high temperature, high humidity or strong electromagnetic interference, thereby affecting the normal operation of the equipment and printing quality.
[0007] To this end, we have proposed a multi-color screen printing process equipment. For the scraper and ink return plate, this device does not require any additional electrical components to drive the scraper and ink return plate to retract and retract, reducing cost investment and facilitating maintenance. Utility Model Content
[0008] The purpose of this utility model is to provide a multi-color screen printing process equipment. For the scraper and the ink return plate, the device does not need to set any redundant electrical components to drive the scraper and the ink return plate to perform telescopic work, thereby reducing the cost investment and facilitating maintenance.
[0009] The technical solutions adopted in this application are as follows:
[0010] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, wherein the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, wherein the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, wherein the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame.
[0011] Furthermore, the telescopic assembly includes an electric telescopic rod arranged on the bracket, and the telescopic end of the electric telescopic rod is provided with the first telescopic rod and the second telescopic rod.
[0012] Furthermore, the first sliding groove matches the first roller, and the first roller and the second roller are both provided with a first smooth surface.
[0013] Furthermore, the second chute matches the second roller, and a second smooth surface is provided on the inner walls of the first chute and the second chute.
[0014] Furthermore, the first trapezoidal block and the second trapezoidal block are both provided with bearing grooves, and the first rotating plate and the second rotating plate are respectively provided inside the two bearing grooves.
[0015] Furthermore, the scraper and the ink return plate are both provided with an anti-adhesion layer.
[0016] The technical effects achieved by this utility model are:
[0017] First, place the ink on the screen plate, and then use the telescopic assembly to drive the first telescopic rod and the second telescopic rod to move to the right. When moving, the first telescopic rod drives the scraper to move the first roller inside the lower trough of the first slide. Figure 3When the first roller is in the position shown, due to the downward movement of the track of the first slide, the scraper moves downward through the extension and contraction of the first telescopic rod and fits the bottom inner wall of the screen plate, thereby performing the ink scraping and printing operation. At the same time, the second telescopic rod drives the ink return plate to make the second roller move inside the second slide. Due to the setting limit of the second trapezoidal block and the second rotating plate, the second roller moves from the top of the second slide, so that the second roller drives the ink return plate to move upward through the second telescopic rod, so that the ink return plate has a certain distance from the bottom inner wall of the screen plate, thereby facilitating the ink scraping and printing operation. Then, when it moves to the right, the first roller moves on the first trapezoidal block on the right to adjust the first rotating plate The plate is pushed out to rotate, so that the first roller moves to the upper trough of the first chute, and the scraper rises and no longer fits with the inner wall of the bottom of the screen plate. When it moves to the upper trough of the first chute, the first rotating plate returns to its original position, so that the first roller can only move through the upper trough of the first chute. At the same time, when the second roller moves to the right, the second roller enters the position of the lower trough of the second chute through the action of gravity and the second telescopic rod. The second roller drives the ink return plate to move down and fit with the inner wall of the bottom of the screen plate, thereby performing the ink return work. Then the electric telescopic rod returns to its original position, so that the ink return plate works to return ink, and the scraper stops working and reciprocates in sequence when moving to the left. For the scraper and ink return plate, this device does not need to set up any redundant electrical components to drive the scraper and ink return plate to retract and retract, which reduces cost investment and is easy to maintain.

It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.
[0025] like Figure 1-4 As shown, the technical solution adopted by the present invention is as follows: a multi-color screen printing process equipment, including a screen plate 1, a bracket is provided on one side of the screen plate 1, a telescopic component is provided on the bracket, a first telescopic rod 2 and a second telescopic rod 3 are provided on the telescopic component, a scraper 4 is provided on the first telescopic rod 2, and an ink return plate 5 is provided on the second telescopic rod 3, and a first chute 6 and a second chute 7 are provided on both side walls of the screen plate 1, the first chute 6 and the second chute 7 are composed of two trapezoidal grooves connected to each other, and a first rotating plate 8 and a fixed plate 9 are hingedly provided on the inner wall of the first chute 6. A first trapezoidal block 9 and a first roller 10 are provided for rolling, the first rotating plate 8 is fitted with the first trapezoidal block 9, a second rotating plate 11 is hingedly provided on the inner wall of the second chute 7, a second trapezoidal block 12 is fixedly provided and a second roller 13 is provided for rolling, the second roller 13 is fitted with the second trapezoidal block 12, the second rotating plate 11 is fitted with the second trapezoidal block 12, the first rotating plate 8, the first trapezoidal block 9, the second rotating plate 11 and the second trapezoidal block 12 are arranged opposite to each other, and the first roller 10 is rotatably connected to the scraper 4, and the second roller 13 is rotatably connected to the ink return plate 5.
[0026] The telescopic assembly includes an electric telescopic rod 14 arranged on a bracket, and a first telescopic rod 2 and a second telescopic rod 3 are provided at the telescopic end of the electric telescopic rod 14. The electric telescopic rod 14 drives the first telescopic rod 2 and the second telescopic rod 3 to move.
[0027] Furthermore, the first telescopic rod 2 and the second telescopic rod 3 are telescopic rods in the prior art, and the positions of the telescopic ends thereof can be telescopically moved inside the fixed tube. Such structures also exist in real life, and will not be elaborated on here.
[0028] The first roller 10 and the second roller 13 are both provided with a first smooth surface, which can reduce friction and make the movement smoother.
[0029] A second smooth surface is provided on the inner wall of the first chute 6 and the second chute 7. The second smooth surface can reduce friction and make the movement smoother.
[0030] In order to achieve multi-color printing, the utility model can be provided with multiple screen plates 1, and inks of different colors are placed inside each screen plate 1, and then printing is performed through the telescopic component.
[0031] The first slide groove 6 matches the first roller 10, and the second slide groove 7 matches the second roller 13. Matching here means that their widths match, so that the first roller 10 can move inside the first slide groove 6 and the second roller 13 can move inside the second slide groove 7 without getting stuck.
[0032] The first trapezoidal block 9 and the second trapezoidal block 12 are both provided with bearing grooves, and the first rotating plate 8 and the second rotating plate 11 are respectively provided inside the two bearing grooves. The first rotating plate 8 and the second rotating plate 11 can enter through the bearing grooves, so that the first roller 10 and the second roller 13 are in a plane when moving, and no steps will appear.
[0033] Both the scraper 4 and the ink return plate 5 are provided with an anti-adhesion layer, which can prevent the ink from adhering.
[0034] The working principle of this utility is: Figure 2 As shown, first, ink is placed on the screen plate 1 (this ink placement can be controlled by electrical components, such as an inkjet printer), and then the first telescopic rod 2 and the second telescopic rod 3 are driven to move to the right by the telescopic assembly. During the movement, the first telescopic rod 2 drives the scraper 4 to move the first roller 10 inside the lower trough of the first slide 6, and then moves to the bottom of the first slide 6. Figure 3When the position is shown, due to the downward movement of the first slide 6, the scraper 4 is moved downward by the extension of the first telescopic rod 2 and is fitted with the bottom inner wall of the screen plate 1, thereby performing the ink scraping and printing operation. At the same time, the second telescopic rod 3 drives the ink return plate 5 to make the second roller 13 move inside the second slide 7. Due to the setting limit of the second trapezoidal block 12 and the second rotating plate 11, the second roller 13 moves from the top of the second slide 7, so that the second roller 13 drives the ink return plate 5 to move upward through the second telescopic rod 3, so that the ink return plate 5 has a certain distance from the bottom inner wall of the screen plate 1, thereby facilitating the ink scraping and printing operation. Then, when it moves to the right, the first roller 10 moves on the first trapezoidal block 9 on the right to push out the first rotating plate 8 And rotate, so that the first roller 10 moves to the interior of the upper trough of the first chute 6, so that the scraper 4 rises and no longer fits with the bottom inner wall of the screen plate 1. When moving to the upper trough of the first chute 6, the first rotating plate 8 returns to its original position, so that the first roller 10 can only move through the interior of the upper trough of the first chute 6. At the same time, when the second roller 13 moves to the right, the second roller 13 enters the position of the lower trough of the second chute 7 through gravity and the action of the second telescopic rod 3. The second roller 13 drives the ink return plate 5 to move down and fit with the bottom inner wall of the screen plate 1, thereby performing ink return work. Then the electric telescopic rod 14 returns to its original position, so that the ink return plate 5 works to return ink, and the scraper 4 is no longer working. It reciprocates in sequence when moving to the left. For the scraper 4 and the ink return plate 5, this device does not need to set any redundant electrical components to drive the scraper 4 and the ink return plate 5 to perform telescopic work, which reduces cost investment and is easy to maintain.
[0035] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
