Description

Technical Field

[0001] The invention relates to the technical field of printers, in particular to a thickness adjustment mechanism for a UV printer. Background Art

[0002] UV printer is a high-tech full-color digital printing machine without plate making, which is not restricted by materials. [1] It can print color photos on T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystal, PVC, acrylic, metal, plastic, stone, leather and other surfaces. No plate making is required, and printing is completed in one go. The colors are bright and rich, wear-resistant, UV-resistant, simple and convenient to operate, and the printing speed is fast, which fully meets the industrial printing standards.

[0003] When the operator is performing surface printing on a square plate made of plastic or wood, the operator needs to adjust the distance between the print head and the square plate according to the thickness of the square plate, so that the distance between the print head and the square plate to be printed on is most appropriate, thereby achieving the best quality of the printed graphics. The existing thickness adjustment mechanism often adjusts the nozzle part, and the fine mechanical structure inside the nozzle, such as the nozzle and oscillation plate, will be constantly subjected to friction and impact under long-term adjustment, resulting in increased wear. Over time, the nozzle may deform, become clogged, and other problems will occur, which will affect the accuracy and effect of inkjet. In order not to affect the printing effect, the nozzle part needs to be replaced in time, but the existing nozzle is relatively expensive, and constantly replacing the nozzle in a short period of time will undoubtedly increase the cost of production, so it needs to be improved.

[0017] Beneficial Effects

[0018] Compared with the prior art, the present invention provides a thickness adjustment mechanism for a UV printer, which has the following beneficial effects:

[0019] 1. This thickness adjustment mechanism for a UV printer, when the pneumatic cylinder is set to start, the pneumatic cylinder will drive the tooth plate to move to the left, at which time the two sides of the tooth plate will be meshed with the gear parts of the two gear arms. As the tooth plate rotates, the gear arms will be driven to rotate, and then the fixed plate will be driven to move through the rotating arm. Since the fixed plate is fixedly connected to the movable bracket, the movable bracket as a whole will move in the front and rear directions in the rectangular groove and the long groove. At the same time, the hinged seat connected to the top of the movable bracket will drive the load-bearing plate to move downward. Through this series of mechanical linkages, the adjustment of the distance between the UV printer nozzle and the printing material is finally achieved, thereby completing the adaptive adjustment of the thickness of the plate.

[0020] 2. The thickness adjustment mechanism for the UV printer has a height setting of the loading plate at the same level as the top position of the conveying wheel. This setting is like laying a smooth and stable transmission track for the printing material, so that the printing material can move forward without hindrance during the transmission process, and there will be no embarrassing situation of the conveying wheel slipping. Slipping is very likely to cause the printing process to no longer be in a continuous state, which greatly reduces the printing effect, resulting in unsatisfactory conditions such as pattern dislocation and uneven color.

[0021] 3. The thickness adjustment mechanism for the UV printer can complete the positioning of the printing material by the operator turning the wheel connected to the right side of the screw, thereby driving the two positioning wheels to move on the screw. There will be no offset problem in the subsequent printing process, and the printing effect will be in the preset state. The printing work is completed perfectly. When operating in cooperation with the thickness adjustment mechanism, the application scope of the equipment will be expanded. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more schemes or examples.

[0035] See also Figure 1 to Figure 7 The present invention proposes a thickness adjustment mechanism for a UV printer, including a main body component 1. During use, when the operator performs surface printing on a square plate made of plastic or wood, the operator needs to adjust the distance between the print head and the square plate according to the thickness of the square plate, so that the distance between the print head and the square plate to be printed on it is most appropriate, thereby making the printed graphics of good quality. The existing thickness adjustment mechanism often adjusts the nozzle part, and the nozzle is adjusted for a long time, and its internal fine mechanical structure, such as the nozzle, oscillation sheet, etc., will be constantly subjected to friction and impact, resulting in increased wear. In the long run, the nozzle may be deformed, blocked, and other problems will affect the accuracy and effect of inkjet. In order not to affect the printing effect, the nozzle part needs to be replaced in time, and the existing nozzle is relatively expensive. Continuously replacing the nozzle in a short period of time will undoubtedly increase the production cost.

[0036] Therefore, during operation, in order to achieve precise mechanical movement and structural stability, the operator first opens two rectangular slots 3 on the left side of the main body 1, and opens two long slots 5 on the right side of the main body 1. The design of these slots is to provide space and guide functions for subsequent component installation. Inside each rectangular slot 3 and long slot 5, the operator movably installs a movable bracket 4, which can slide or move freely in the rectangular slot 3 and long slot 5 to achieve its function. In order to further enhance the stability of the structure and ensure the coordinated movement between the components, the operator fixes each group of component movable brackets 4 together through a connecting member fixing plate 7. This connection method enables the component movable brackets 4 to maintain synchronization and consistency during the movement. In addition, the top of each movable bracket 4 is connected to an articulated seat 9 in an articulated manner. This articulated design allows the articulated seat 9 to rotate or swing within a certain range, thereby adapting to different movement requirements. The tops of the four articulated seats 9 are movably connected to the trapezoidal slots 25 opened at the bottom of the carrier plate 2. The design of the trapezoidal groove 25 plays a key limiting role. It strictly constrains the movement trajectory of the four articulated seats 9, so that the articulated seats 9 always move along the predetermined route during the movement process without deviating from the predetermined trajectory. Through this ingenious structural design, the entire device can maintain a high degree of stability and accuracy during operation, and the movements between various components are coordinated and consistent, thereby ensuring the efficient operation and reliability of the entire system. At the same time, filter plates 19 are set on both sides of the main body component 1. The setting of the filter plate 19 can effectively discharge the hot air flow accumulated inside 1, and will not make the air pressure inside 1 too high, thereby affecting the movement of the carrier plate 2.

[0037] When printing, if the thickness of the plate to be printed is relatively thick, the initial distance between the plate and the print head will be relatively close. In order to ensure that the distance between the printing material and the print head is in the best position, so as to obtain a more ideal printing effect, the operator needs to perform a series of operations on the adjustment mechanism of the printing device. When printing, if the thickness of the plate to be printed is relatively thick, the initial distance between the plate and the print head will be relatively close. In order to ensure that the distance between the printing material and the print head is in the best position, so as to obtain a more ideal printing effect, the operator needs to perform a series of operations on the adjustment mechanism of the printing device. Specifically, the operator hinges two sections of rotating arms 30 on both sides of the fixed plate 7. The other end of the rotating arm 30 is hinged with a gear arm 6. Through the design of this two-section connecting arm, not only the movement of the entire mechanism is smoother, but also the direction of force transmission is changed. The advantage of this design is that even if the same load-bearing capacity is maintained, the required driving force does not need to be too large, thereby reducing the energy consumption and operating cost of the equipment to a certain extent, and achieving economic benefits. The other end of the gear arm 6 is connected to a gear, and its bottom is movably mounted on the inner bottom end of the main body part 1. On the inner side of the two gear arms 6, there is a tooth plate 29 meshingly connected. A pneumatic cylinder 8 is fixedly connected to the right side of the tooth plate 29, and the pneumatic cylinder 8 is fixedly installed on the right side of the main body 1. When the operator starts the pneumatic cylinder 8, the pneumatic cylinder 8 will drive the tooth plate 29 to move to the left. At this time, the two sides of the tooth plate 29 will be meshed and connected with the gear parts of the two gear arms 6. As the tooth plate 29 rotates, the gear arm 6 will be driven to rotate, and then the fixed plate 7 will be driven to move through the rotating arm 30. Since the fixed plate 7 is fixedly connected to the movable bracket 4, the movable bracket 4 as a whole will move in the rectangular groove 3 and the long groove 5 along the front and rear direction. At the same time, the hinge seat 9 connected to the top of the movable bracket 4 will drive the bearing plate 2 to move downward. Through this series of mechanical linkages, the adjustment of the distance between the UV printer nozzle and the printing material is finally achieved, thereby completing the adaptive adjustment of the thickness of the plate.

[0038] When the printed material is thin, the operator starts the pneumatic cylinder 8, which will drive the toothed plate 29 to move to the right, and then drive the two gear arms 6 to move to the left, thereby driving the rotating arm 30. At this time, the arm spans of the gear arms 6 and the rotating arms 30 will be shortened, thereby driving the movable bracket 4 as a whole to move inward on the round rod 27 installed in the rectangular groove 3 and the long groove 5. At the same time, a spring 28 is movably sleeved on the outer surface of the round rod 27, one end of the spring 28 is connected to the round rod 27, and the other end is connected to the movable bracket 4. Then the hinged seat 9 connected to the top of the movable bracket 4 will drive the bearing plate 2 to move upward, and finally the distance between the UV printer nozzle and the printed material is adjusted, thereby completing the adaptive adjustment of the plate thickness.

[0039] The operator places the printing material on the right side of the carrier plate 2. At this time, the operator needs to position the printing material according to the width of the printing material to prevent deviation during the subsequent printing and transmission process, thereby affecting the printing effect. The operator connects a carrier 21 to the right side of the top of the main part 1. The height of the carrier 21 is slightly lower than the height of the carrier plate 2. This setting can make the printing material smooth during the transmission process. Then a screw 23 is installed inside the carrier 21, and positioning wheels 22 are threadedly sleeved on both sides of the screw 23. Rollers are movably installed inside the positioning wheel 22. The setting of the positioning wheel 22 not only plays a positioning role, but also the rollers inside the positioning wheel 22 will be more conducive to the subsequent transmission movement. At the same time, the threads on both sides of the screw 23 are rotated in opposite directions. At this time, the operator rotates the rotating wheel 26 connected to the right side of the screw 23, thereby driving the two positioning wheels 22 to move on the screw 23, thereby completing the positioning problem of the printing material. There will be no deviation problem in the subsequent printing process, which will make the printing effect as preset, and perfectly complete the printing work.

[0040] The operator accurately started the device output motor 17 set on the right side of the equipment carrier plate 2 in accordance with the established process. In an instant, the output shaft of the output motor 17 passed through the left side of the carrier plate 2 and smoothly extended to the internal space of the carrier plate 2. It is worth noting that the output shaft of the output motor 17 is connected to the gear arm 6. In addition, two groups of conveying wheels 16 and output motors 17 are set. These two groups of conveying wheels 16 and output motors 17 are evenly arranged on the rear side of the carrier plate 2. With the start of the output motor 17, these two groups of conveying wheels 16 and output motors 17 cooperate exquisitely, which will drive the conveying wheels 16 closely connected thereto to rotate regularly. At this time, the printing materials after the previous fine positioning are ready. Under the orderly movement of the conveying wheel 16, the printing materials are smoothly and accurately transported to the carrier plate 18. The height setting of the carrier plate 18 is also ingenious, and its height is at the same horizontal position as the vertex position of the conveying wheel 16. Such an ingenious arrangement is like laying a smooth and steady conveying track for the printed material, so that the printed material can move forward without any hindrance during the conveying process of the printed material, and there will be no embarrassment of slipping of the conveying wheel 16. Slipping is very likely to cause the printing process to no longer be in a continuous state, thereby greatly reducing the printing effect, resulting in unsatisfactory conditions such as pattern misalignment and color unevenness.

[0041] During the conveying process, a control box 10 and a parking platform 12 are installed on both sides of the top of the main part 1, and a sensing device is provided inside the control box 10 and the parking platform 12. When the printing material is at the same horizontal position as the inner side of the control box 10 and the parking platform 12, the printing device 14 movably installed on the top of the parking platform 12 will enter the working state, and the printing nozzle set at the bottom of the printing device 14 will be controlled. Then, a mounting plate 11 is connected to the top of the control box 10, and the other end of the mounting plate 11 is connected to the parking platform 12. A long rod 13 is movably sleeved inside the mounting plate 11, and the right end of the long rod 13 penetrates the mounting plate 1 1 and extends to the outer surface of the mounting plate 11. A power motor 20 is installed on the right side of the mounting plate 11. The output shaft of the control box 10 is fixedly connected to the long rod 13, and the power motor 20 is located inside the control box 10. At this time, under the operation of the power motor 20, the mounting plate 11 will drive the printing device 14 to reciprocate as a whole. At the same time, the printing lamps 15 arranged on both sides of the bottom of the printing device 14 will illuminate the graphics or text printed on the material. The setting of the printing lamp 15 can ensure that the ink is dried instantly during the printing process, and avoid the ink from being contaminated by dust in the air, thereby improving the clarity and firmness of the pattern. In addition, this rapid curing process can also significantly increase the printing speed and improve production efficiency. At the same time, the parking platform 12 adopts cold light source technology, which will not cause high temperature damage to the printing material, so it can be applied to a variety of materials, including hard materials (such as glass, metal, wood) and flexible materials (such as leather, plastic, fabric).

[0042] With the cooperation of the conveying wheel 16, the long rod 13, the power motor 20, the printing device 14 and the printing lamp 15, the required printed graphics or texts can be completed.
