[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-speed precision printing machine includes a regulation mechanism. The front end of the regulation mechanism is threadedly connected with an electric slide rail. The front end of the electric slide rail is provided with an adjusting mechanism at the lower end. The adjusting mechanism includes two moving grooves, two fixing blocks, an adjusting block, a moving block, multiple clamping grooves, a connecting platform, an installation groove, a doctor blade, a fixing plate, a spring, a sliding groove, and a clamping block;

[0008] The front end of the electric slide rail is provided with a clamping mechanism. The clamping mechanism includes two first cylinders, two connecting blocks, a screen plate, a printing plate, a protective frame, a double-headed cylinder, and two clamping plates. The front end of the regulation mechanism is fixedly provided with a workbench, and the upper end of the workbench is fixedly provided with an operation panel.

[0009] Further, the opposite sides of the two first cylinders are respectively fixedly arranged on both sides inside the protective frame, the output ends of the two first cylinders are respectively fixedly arranged on the upper ends of the two connecting blocks, and the opposite sides of the two connecting blocks are fixedly arranged on both sides of the mesh plate.

[0010] Further, the lower end of the printing plate is arranged on the upper end of the conveying mechanism, a protective cover is hingedly arranged at the front end of the protective frame, the outside of the double-headed cylinder is fixedly arranged inside the operation plate, the opposite ends of the two clamping plates are respectively fixedly arranged at the front and rear ends of the output end of the double-headed cylinder, and the outside of the two clamping plates are both slidably arranged inside the operation plate.

[0011] Further, the upper end of the connecting platform is fixedly arranged at the lower end of the electric slide rail, the outside of the two fixed blocks are respectively slidably arranged inside the two moving grooves, and the outside of the two moving grooves are respectively opened on both sides of the connecting platform.

[0012] Further, the outside of the moving block is slidably arranged inside the connecting platform, the upper end of the fixing plate is fixedly arranged at the lower end of the moving block, the lower end of the fixing plate is slidably arranged inside the installation groove, the outside of the installation groove is opened at the upper end of the ink scraping knife, and the outside of the upper end of the ink scraping knife is slidably arranged at the lower end inside the connecting platform.

[0013] Further, a plurality of the card slots are respectively opened at the lower end inside the connecting platform, the outside of the adjusting block is slidably arranged at one side inside the sliding groove, the outside of the sliding groove is opened at one side of the outside of the clamping block, and the lower end of the clamping block is clamped and arranged inside one of the plurality of card slots.

[0014] Further, the upper end of the spring is fixedly arranged at the upper end inside the moving block, the lower end of the spring is fixedly arranged at the upper end of the clamping block, and the outside of the clamping block is slidably arranged at the lower end inside the moving block.

[0016] The utility model has the following beneficial effects:

[0017] 1. For the high-speed precision printing machine proposed by the utility model, when it is necessary to adjust the distance between the ink scraping knife and the ink, move the adjusting block to slide it in the sliding groove, which causes the clamping block to move and compress the spring, and at the same time releases its connection with the card slot. After the clamping block is separated from the card slot, by continuously moving the adjusting block, drive the moving block to slide inside the connecting platform and synchronously drive the fixing plate to move. Since the fixing plate slides in the installation groove at the upper end of the ink scraping knife, the ink scraping knife is driven to slide inside the connecting platform, completing the adjustment of the position of the ink scraping knife. The operation is simple and fast, without the need for complex tools and steps, and can easily adapt to different printing requirements.

[0018] 2. When the high-speed precision printing machine proposed by the present utility model is in operation, the conveying mechanism automatically conveys the printing plate to the upper end position of the operation plate. The regulation mechanism drives the electric slide rail and the screen plate to move downward, and synchronously moves the protective frame downward to wrap the operation plate, forming a closed printing environment, ensuring the stability and safety of the printing process, preventing dust from entering and affecting the printing effect. Before the printing starts, the electric telescopic rod drives the screen plate to move downward, causing the first cylinder to extend. As a result, the gas inside the double-headed cylinder is pumped into the first cylinder, causing the double-headed cylinder to contract. The contraction of the double-headed cylinder drives the clamping plate at its output end to slide inside the operation plate, thereby realizing the automatic clamping operation of the printing plate, which not only improves the production efficiency but also makes the printing plate stable during the printing process and improves the printing accuracy.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figure 1-4 , an embodiment provided by the present invention is as follows:

[0029] A high-speed precision printing machine includes a control mechanism 1. The front end of the control mechanism 1 is threadedly connected with an electric slide rail 9. At the lower end of the front end of the electric slide rail 9, an adjustment mechanism 8 is provided. The adjustment mechanism 8 includes two moving grooves 801, two fixing blocks 802, an adjustment block 803, a moving block 804, a plurality of card slots 805, a connecting table 806, an installation groove 807, a doctor blade 808, a fixing plate 809, a spring 810, a sliding groove 811, and a clamping block 812. The upper end of the connecting table 806 is fixedly arranged at the lower end of the electric slide rail 9. The outer parts of the two fixing blocks 802 are respectively slidably arranged inside the two moving grooves 801. The outer parts of the two moving grooves 801 are respectively opened on both sides of the connecting table 806. The outer part of the moving block 804 is slidably arranged inside the connecting table 806. The upper end of the fixing plate 809 is fixedly arranged at the lower end of the moving block 804. The lower end of the fixing plate 809 is slidably arranged inside the installation groove 807. The outer part of the installation groove 807 is opened at the upper end of the doctor blade 808. The outer part of the doctor blade 808 is slidably arranged at the lower end inside the connecting table 806. The outer parts of the plurality of card slots 805 are respectively opened at the lower end inside the connecting table 806. The outer part of the adjustment block 803 is slidably arranged inside the sliding groove 811 at one side. The outer part of the sliding groove 811 is opened at one side of the outer part of the clamping block 812. The lower end of the clamping block 812 is clamped and arranged inside one of the plurality of card slots 805. The upper end of the spring 810 is fixedly arranged at the upper end inside the moving block 804. The lower end of the spring 810 is fixedly arranged at the upper end of the clamping block 812. The outer part of the clamping block 812 is slidably arranged at the lower end inside the moving block 804;

[0030] Specifically, when it is necessary to adjust the distance between the doctor blade 808 and the ink, the operator manually moves the adjusting block 803, causing it to slide in the sliding groove 811 inside the clamping block 812, prompting the clamping block 812 to move upward inside the moving block 804, and simultaneously squeezing the spring 810, so that the clamping block 812 gradually releases its connection with the clamping groove 805, preparing for the adjustment. With the release of the connection between the clamping block 812 and the clamping groove 805, the adjusting block 803 can freely drive the moving block 804 to slide inside the connecting platform 806. At this time, the fixing blocks 802 on both sides of the moving block 804 slide synchronously in the moving grooves 801, providing guiding and stable effects for the movement of the moving block 804. At the same time, the lower end of the outer side of the fixing plate 809 is slidably arranged on the upper end of the doctor blade 808, and it is fixedly connected to the moving block 804. When the moving block 804 slides accordingly, the doctor blade 808 will be pulled, thereby realizing the fine adjustment of the distance between the doctor blade 808 and the ink. After the adjustment is completed, the operator releases the force applied to the adjusting block 803, so that the adjusting block 803 automatically resets under the elastic force of the spring 810. The sliding groove 811 ensures the smoothness of the sliding reset. The resilience of the spring 810 drives the clamping block 812 to move downward, causing it to automatically snap into a new clamping groove 805 inside the connecting platform 806, realizing the stable fixation of the position of the doctor blade 808. For the stability and precision of the subsequent printing process, the adjustment mechanism 8 not only simplifies the operation steps of adjusting the position of the doctor blade 808, improves the adjustment efficiency, but also improves the accuracy and stability of the adjustment process.

[0031] Refer to Figure 1-6 , a clamping mechanism 2 is provided at the front end of the electric slide rail 9. The clamping mechanism 2 includes two first cylinders 201, two connecting blocks 202, a mesh plate 203, a printing plate 204, a protective frame 205, a double-headed cylinder 206 and two clamping plates 207. A workbench 5 is fixedly provided at the front end of the control mechanism 1. An operation panel 3 is fixedly provided on the upper end of the workbench 5. The opposite sides of the two first cylinders 201 are respectively fixedly provided on both sides inside the protective frame 205. The output ends of the two first cylinders 201 are respectively fixedly provided on the upper ends of the two connecting blocks 202. The opposite sides of the two connecting blocks 202 are fixedly provided on both sides of the mesh plate 203. The lower end of the printing plate 204 is arranged on the upper end of the conveying mechanism 4. A protective cover 6 is hingedly provided at the front end of the protective frame 205. The double-headed cylinder 206 is fixedly provided inside the operation panel 3. The opposite ends of the two clamping plates 207 are respectively fixedly provided at the front and rear ends of the output end of the double-headed cylinder 206. The outer sides of the two clamping plates 207 are both slidably arranged inside the operation panel 3. A conveying mechanism 4 is fixedly provided on the upper end of the workbench 5. A control panel 7 is fixedly provided on one side near the front end of the workbench 5. The electric slide rail 9 is threadedly connected to the front end of the control mechanism 1;

[0032] Specifically, in the actual operation process, first place the printed circuit board 204 on the conveying mechanism 4 on the workbench 5, start the printing machine through the control panel 7, so that the conveying mechanism 4 operates, and the printed circuit board 204 is accurately sent to the upper end of the operation board 3 to prepare for the subsequent steps. Subsequently, the regulating mechanism 1 is started to drive the electric slide rail 9 and the screen plate 203 to move downward synchronously. The regulating mechanism 1 and the conveying mechanism 4 are both existing mechanisms, which will not be repeated in this specification. At this time, the protective frame 205 also moves downward, automatically wrapping the operation board 3 to form a closed working area, ensuring the safety and stability of the operation. Moreover, when the device is not in use, the protective frame 205 can prevent dust and impurities from falling onto the screen plate 203, thereby reducing the impact on printing and making the internal printing work of the printing machine cleaner. During the printing process, the electric telescopic rod drives the screen plate 203 to move downward, driving the output end of the first cylinder 201 and the connecting block 202 inside the protective frame 205 fixed thereto to move downward synchronously. Since the first cylinder 201 and the double-headed cylinder 206 are connected by an air pipe, when the output end of the first cylinder 201 extends, the gas inside the double-headed cylinder 206 will be drawn into the first cylinder 201, causing the double-headed cylinder 206 to automatically contract. The contraction action of the double-headed cylinder 206 drives the clamping plate 207 at its output end to slide inside the operation board 3, thereby realizing the automatic and precise clamping of the printed circuit board 204, improving the stability and precision during the printing process, not only increasing the production efficiency, but also enhancing the stability and safety of the printing process.

[0033] Working principle: In actual use, first place the printed circuit board 204 on the conveying mechanism 4, so that the conveying mechanism 4 drives the printed circuit board 204 to reach the upper end of the operation board 3. At this time, the regulating mechanism 1 will drive the electric slide rail 9 and the screen plate 203 to move downward synchronously, and then the protective frame 205 will move downward synchronously to wrap the operation board 3. When printing, the electric telescopic rod drives the screen plate 203 to move downward, causing the connecting block 202 at the output end of the first cylinder 201 fixed inside the protective frame 205 to be driven downward. Since the first cylinder 201 and the double-headed cylinder 206 are connected by an air pipe, when the output end of the first cylinder 201 extends, the gas inside the double-headed cylinder 206 will be drawn into the first cylinder 201, causing the double-headed cylinder 206 to contract, and then driving the clamping plate 207 at its output end to slide inside the operation board 3, thereby realizing the automatic clamping operation of the printed circuit board 204 and improving the stability.

[0034] Secondly, when it is necessary to adjust the distance between the doctor blade 808 and the ink, the adjusting block 803 is moved to slide in the sliding groove 811 formed inside the clamping block 812, so that the clamping block 812 moves upward inside the moving block 804 and compresses the spring 810, thereby gradually releasing the connection with the clamping groove 805. At this time, the moving block 804 can be driven by the adjusting block 803 to slide inside the connecting platform 806. At this time, the fixing blocks 802 on both sides of the moving block 804 will slide inside the moving groove 801, and the movement of the moving block 804 will synchronously drive the fixing plate 809 to move. Since the fixing plate 809 slides on the upper end of the doctor blade 808, the movement of the fixing plate 809 will cause the doctor blade 808 to slide inside the connecting platform 806, thus completing the adjustment of the position of the doctor blade 808. After completion, by releasing the force applied to the adjusting block 803, at this time the adjusting block 803 will slide in the sliding groove 811 to reset, and the spring 810 will rebound to drive the clamping block 812 to move downward, prompting the clamping block 812 to be inserted into a new clamping groove 805, which is convenient to operate.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
