Description

Technical Field

[0001] The utility model relates to the technical field of silk screen printing machines, in particular to a silk screen printing table. Background Art

[0002] The silk screen printing table, also known as the silk screen printing machine, refers to the silk screen printing that uses the silk screen as the base to make a silk screen printing plate with pictures and texts. The silk screen printing machine consists of five major elements, the silk screen printing plate, scraper, ink, printing table and substrate. The printing is carried out based on the basic principle that the mesh holes of the graphic part of the silk screen printing plate can pass the ink, while the mesh holes of the non-graphic part cannot pass the ink. When printing, ink is poured into one end of the silk screen printing plate, and a certain pressure is applied to the ink part of the silk screen printing plate with a scraper. At the same time, it moves at a uniform speed toward the other end of the silk screen printing plate. During the movement, the ink is squeezed from the mesh holes of the graphic part onto the substrate by the scraper. It is usually composed of a chassis, an operating table, a printing table, a mobile frame, a scraper and a silk screen printing plate, and the whole is semi-automatic.

[0003] The above-mentioned and existing related technologies often have the following defects: when personnel print the screen on the substrate, they place the substrate on the printing table, and then use a scraper to slide across the surface of the screen printing plate to brush the ink through the mesh holes onto the surface of the substrate. The printing patterns of different substrates are different, so it is necessary to use a similar special screen printing plate, so that the mesh holes of the screen printing plate and the placement position of the substrate need to be accurately aligned. However, personnel usually place it directly on the printing table by naked eye observation, which makes it difficult to accurately align the mesh holes of the screen printing plate with the substrate, resulting in a certain degree of offset after the pattern on the substrate is printed.

[0004] For this purpose, we propose a silk screen printing station. Utility Model Content

A positioning structure 9 is provided on one side of the trapezoidal bar 808, which achieves the effect of positioning the side of the substrate, so that when printing some special specifications of substrates, a certain positioning can be performed to maintain stability, thereby further improving the guiding strength of the overall structure to the substrate, thereby improving the applicability of the device.

[0030] The specific settings and functions of the adjustment structure 8 and the positioning structure 9 are described in detail below.

[0031] like Figure 2 and Figure 3 as well as Figure 4 As shown, the adjustment structure 8 includes a fixed frame 801, the lower surface of the fixed frame 801 is fixedly connected to the chassis 1, the upper surface of the fixed frame 801 is threaded with a driving rod 802, the inner wall of the fixed frame 801 is slidably connected with a slide bar 803, the lower end of the driving rod 802 is slidably connected to the slide bar 803, the upper surface of the slide bar 803 is fixedly connected with an L-shaped rod 804, the long arm of the L-shaped rod 804 is fixedly connected with a connecting tube 805, the inner wall of the connecting tube 805 is rotatably connected with an adjusting rod 806, the arc surface of the adjusting rod 806 is sleeved with a circular tube 807, one side of the trapezoidal bar 808 is fixedly connected to one end of the circular tube 807, the lower surface of the trapezoidal bar 808 is slidably connected to the printing table 3, the adjusting rod 806 is a threaded rod, the inner wall of the circular tube 807 is threadedly connected to the adjusting rod 806, and the adjusting rod 806 rotates in the connecting tube 805 with the help of an automatic The body thread drives the round tube 807 to move horizontally, and the adjusting rod 806 can adjust the horizontal position of the trapezoidal bar 808. The inner wall of the fixed frame 801 is fixedly connected with a damping pad 809, and the damping pad 809 is a silicone pad. The sliding bar 803 slides from the upper surface of the damping pad 809. The damping pad 809 can increase the friction between the sliding bar 803 and the fixed frame 801, thereby reducing the moving speed of the sliding bar 803 to facilitate personnel to adjust the position of the trapezoidal bar 808. The lower surface of the sliding bar 803 is provided with an inner groove 810, and the upper surface of the damping pad 809 is slidably connected to the inner wall of the inner groove 810. The inner wall of the inner groove 810 of the sliding bar 803 slides from the upper surface of the damping pad 809. The inner groove 810 maintains the filling between the fixed frame 801 and the sliding bar 803 to avoid the damping pad 809 squeezing the sliding bar 803 and causing the sliding bar 803 to shake.

[0032] like Figure 2 and Figure 3 As shown, the positioning structure 9 includes a U-shaped rod 91, one end of which is fixedly connected to the trapezoidal bar 808, the arc surface of the U-shaped rod 91 is rotatably connected to a rotating drum 92, the arc surface of the rotating drum 92 is fixedly connected to a side plate 93, the lower surface of the side plate 93 abuts against the printing table 3, and one side of the side plate 93 is fixedly connected to a side rod 94, which is located at a position of the side plate 93 away from the trapezoidal bar 808. The effects achieved by the above components are: moving the side rod 94 drives the side plate 93 to move, and the side rod 94 plays a role in better rotating the side plate 93, the upper surface of the side plate 93 is fixedly connected to an elastic rope 95, the other end of the elastic rope 95 is fixedly connected to the inclined surface of the trapezoidal bar 808, the rotation of the side plate 93 drives the elastic rope 95 to stretch, and the elastic force of the elastic rope 95 is used to achieve the effect of quickly resetting the side plate 93 to the rear.

[0033] Working principle: When it is necessary to print a pattern on a substrate, firstly, the specially made screen printing plate 7 is limited under the scraper 5 through the connecting frame 6, and then the substrate is placed on the upper surface of the printing table 3, so that the printing position of the substrate is accurately aligned with the mesh of the screen printing plate 7, and then the trapezoidal bar 808 is moved from the upper surface of the printing table 3 to the side close to the substrate, and the round tube 807 drives the connecting tube 805 to move through the trapezoidal bar 808 with the help of the adjusting rod 806, and the L-shaped rod 804 drives the sliding bar 803 to slide from the inner wall of the fixed frame 801 through the connecting tube 805. At this time, the sliding bar 803 is moved from the inner wall of the fixed frame 801 to the inner wall of the fixed frame 801. The inner wall of the inner groove 810 of the strip 803 slides on the surface of the damping pad 809. The inner groove 810 plays a role in maintaining the filling between the fixed frame 801 and the slide bar 803 to prevent the damping pad 809 from squeezing the slide bar 803 and causing the slide bar 803 to shake. The damping pad 809 can increase the friction between the slide bar 803 and the fixed frame 801, thereby reducing the moving speed of the slide bar 803 and facilitating personnel to adjust the position of the trapezoidal strip 808. After the trapezoidal strip 808 is attached to the substrate, the driving rod 802 is rotated to the side close to the slide bar 803 through the fixed frame 801. The lower end of the driving rod 802 is pressed against the slide bar 803, so that the slide bar 803 is limited in the fixed frame 801, and then the adjusting rod 806 is rotated. The adjusting rod 806 plays a role in adjusting the lateral position of the trapezoidal bar 808. The adjusting rod 806 rotates on the inner wall of the connecting tube 805 and drives the round tube 807 to move horizontally with its own thread. The trapezoidal bar 808 drives the positioning structure 9 to fit with the side of the substrate through the round tube 807. At this time, the adjustment of the limit position of the trapezoidal bar 808 is completed. Finally, the scraper 5 of the movable frame 4 is opened through the operating table 2. After the scraper 5 slides from the upper surface of the screen printing plate 7, it applies a certain pressure to the ink part on the screen printing plate 7 and moves at a constant speed toward the other end of the screen printing plate 7. During the movement, the ink is squeezed from the mesh of the graphic part of the screen printing plate 7 by the scraper 5 onto the substrate. At this time, the mesh pattern is printed on the substrate. The printed substrate is then removed, and the positioning structure 9 is rotated to place the unprinted substrate on the upper surface of the printing table 3 and fit it with one side of the side plate 93 and the trapezoidal bar 808 to be positioned. Then, the substrate is printed again by moving the scraper 5.

[0034] When it is necessary to laterally position the substrate on one side of the trapezoidal bar 808, first, the side plate 93 is driven to rotate toward the side close to the printing table 3 with the help of the side rod 94. The side rod 94 plays a role in better rotating the side plate 93, and the rotating drum 92 rotates from the arc surface of the U-shaped rod 91 through the side plate 93. At this time, the elastic rope 95 is in a stretched state due to the rotation of the side plate 93. Until the side plate 93 is in contact with the printing table 3, the substrate is placed on the printing table 3, and then the substrate is moved to be in contact with one side of the trapezoidal bar 808 and one side of the side plate 93 to locate the lateral position of the substrate. Finally, the side rod 94 is released. At this time, the elastic rope 95 is in a contracted state, driving the side plate 93 to rotate. The side plate 93 drives the rotating drum 92 to rotate from the arc surface of the U-shaped rod 91 and separate from the printing table 3. With the help of the elastic force of the elastic rope 95, the side plate 93 is quickly reset to the rear, so that the height of the side plate 93 itself will not affect the contact between the screen printing plate 7 and the substrate.
