Description

Technical Field

[0001] This utility model relates to the field of fully automatic screen printing machine technology, and in particular to a printing mechanism for a fully automatic screen printing machine. Background Technology

[0002] In the current printing industry, screen printing machines, as a common printing equipment, are widely used in printing various flat materials. However, traditional screen printing machine mechanisms often suffer from problems such as inconvenient adjustment, poor adaptability, and difficult maintenance. For example, when clamping the template, traditional printing mechanisms can often only accommodate templates of fixed sizes. Different clamping devices are required for templates of different sizes, which not only increases costs but also reduces production efficiency. Furthermore, during the printing process, the squeegee adjustment in traditional mechanisms is often inflexible, making it difficult to achieve printing at different angles and tilts, thus limiting the diversity and quality of printing. At the same time, the squeegee is prone to wear after prolonged use and requires replacement or cleaning, but the replacement and cleaning of the squeegee in traditional mechanisms is cumbersome and inconvenient to maintain. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of inconvenient adjustment, poor adaptability and difficult maintenance of the printing mechanism of the existing screen printing machine. When clamping the template, the traditional printing mechanism can only adapt to the template of a fixed size. Different clamping devices need to be changed for templates of different sizes, which not only increases the cost but also reduces the production efficiency. The traditional printing mechanism is cumbersome to operate and difficult to maintain in terms of squeegee replacement and cleaning. Therefore, a fully automatic printing mechanism for screen printing machine is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A printing mechanism for a fully automatic screen printing machine includes a frame, two symmetrically arranged first vertical plates are fixedly connected to the inner wall of the frame, a common connecting rod is fixedly connected between the two first vertical plates, a common sliding rod is fixedly connected between the two first vertical plates, a movable seat is slidably sleeved on the outer wall of the sliding rod, and a driving component for driving the movable seat to move is provided inside the frame.

[0006] The movable base is internally equipped with a printing component for printing;

[0007] The frame is equipped with two sets of clamping components for holding the template.

[0008] In one possible design, the drive assembly includes a fixed plate fixedly connected inside the frame, a servo motor fixedly connected to one side of the fixed plate, a lead screw fixedly connected to the output shaft of the servo motor, and one end of the lead screw threaded through the movable seat.

[0009] In one possible design, the printing assembly includes two symmetrically arranged fixed shafts that penetrate the inner wall of one side of the movable seat. Both ends of the fixed shafts are provided with threaded grooves, and the internal threads of the threaded grooves are connected to second mounting screws. The outer wall of the fixed shafts is fixedly fitted with two symmetrically arranged side strip plates, and one side of the second mounting screw and one side of the side strip plate respectively abut against the two sides of the movable seat.

[0010] In one possible design, two symmetrically arranged rotating shafts are rotatably connected between the side strip plates. The outer walls of the two rotating shafts are fixedly fitted with the same U-shaped plate. A first connecting seat is fixedly connected to one side of the U-shaped plate. A second connecting seat is fixedly connected between the first connecting seat and the U-shaped plate. A second mounting plate is fixedly connected inside the second connecting seat. A first mounting plate is provided on one side of the second mounting plate. A scraper is engaged between the second mounting plate and the first mounting plate. The second mounting plate and the first mounting plate are fixedly connected by a plurality of first mounting screws.

[0011] In one possible design, the clamping assembly includes an upper pressure plate and a lower pressure plate, with two symmetrically arranged circular holes between the upper and lower pressure plates. Two symmetrically arranged first fixing screws pass through the internal threads of the upper and lower pressure plates, and the first fixing screws are used to fix the lower pressure plate and the upper pressure plate.

[0012] In one possible design, a second vertical plate is fixedly connected to the bottom of the lower pressure plate, a clamping plate is fixedly connected to one side of the second vertical plate, and two symmetrically arranged third fixing screws are threaded through the top of the clamping plate.

[0013] In this application, when in use, the servo motor can be started, the output shaft of the servo motor drives the lead screw to rotate, the lead screw drives the moving seat to move laterally, and the moving seat drives the two scrapers below to move laterally, thereby completing the printing process;

[0014] Furthermore, during use, the template can be clamped by two clamping plates, and the template can be fixed by the third fixing screw. The second vertical plate can be fixed to the outer wall of the screw rod and slide rod by the upper and lower pressure plates. At this time, the position of the clamping plates on both sides can be adjusted to adapt to templates of different sizes. The lower and upper pressure plates can be tightened by the first fixing screw to fix the clamping plates.

[0015] Furthermore, the relative height of the two scrapers can be adjusted according to the actual situation. By unscrewing the second mounting screw, the angle of the fixed shaft and the side strip plate can be adjusted. After the adjustment is completed, a height difference appears between the scrapers on both sides, which can better achieve the printing process in a tilted state. After screwing the second mounting screw in again, the fixed shaft can be fixed.

[0016] After the scraper has been used, it needs to be cleaned. At this time, the first mounting screws can be unscrewed to separate the second mounting plate from the first mounting plate. This loosens the scraper clamped between the second and first mounting plates, making it easier to remove and replace the scraper.

[0017] Beneficial effects: By incorporating an adjustable clamping assembly, the printing mechanism of this application can adapt to templates of different sizes without requiring replacement of the clamping device, thus reducing costs and improving production efficiency. Simultaneously, the relative height and angle of the squeegee can be flexibly adjusted, allowing the printing mechanism to better achieve the printing process in an inclined state, thereby improving the diversity and quality of printing.

[0018] In the printing mechanism of this application, the scraper is fixed to the mounting plate by simple screws, facilitating disassembly and replacement. Furthermore, the clamping method between the scraper and the mounting plate makes cleaning easier, reducing maintenance difficulty and cost.

[0019] By using a servo motor to drive the lead screw to rotate, which in turn moves the moving seat and squeegee laterally, the printing process is automated, improving printing accuracy and stability. Attached Figure Description

[0028] Example 1

[0029] Reference Figure 1-6 A printing mechanism includes: a frame 1, two symmetrically arranged first vertical plates 8 fixedly connected to the inner wall of the frame 1, a common connecting rod 9 fixedly connected between the two first vertical plates 8, a common sliding rod 23 fixedly connected between the two first vertical plates 8, a movable seat 4 slidably sleeved on the outer wall of the sliding rod 23, and a driving assembly for driving the movable seat 4 to move inside the frame 1. The driving assembly includes a fixed plate 6 fixedly connected inside the frame 1, a servo motor 7 fixedly connected to one side of the fixed plate 6, a lead screw 3 fixedly connected to the output shaft of the servo motor 7, and one end of the lead screw 3 threaded through the movable seat 4.

[0030] The movable base 4 is internally equipped with a printing assembly for printing. The printing assembly includes two symmetrically arranged fixed shafts 28 that penetrate one inner wall of the movable base 4. Each fixed shaft 28 has a threaded groove 26 at both ends, and a second mounting screw 27 is threaded into the groove 26. Two symmetrically arranged side strip plates 19 are fixedly fitted onto the outer wall of the fixed shafts 28.
