Description

Technical Field

[0001] This utility model relates to the field of squeegee technology for printing machines, specifically a squeegee for screen printing machines. Background Technology

[0002] A screen printing machine is a machine that uses a screen printing plate to print. It is a representative printing equipment among stencil printing machines. In addition to silk, the materials used to make the screen can also be nylon, copper, steel or stainless steel wire. When using a screen printing machine, a squeegee is needed to scrape the ink.

[0003] A search revealed a patent, CN213973089U, which discloses a squeegee for a screen printing machine. The squeegee includes a squeegee and a squeegee fixing plate. The fixing plate is mounted on the top surface of the squeegee. An installation groove is formed in the middle of the back of the squeegee, and limiting grooves are formed on both sides of the back of the squeegee near the installation groove. An anti-detachment clip is installed at the end of the limiting groove away from the installation groove. This invention ensures a more secure installation of the squeegee and fixing plate. The detachable design of the squeegee and fixing plate facilitates replacement of the squeegee, making it convenient to use. The first and second limiting clips can be connected to squeegees of different lengths, improving applicability. The meshing between the first and second gears and the first and second connecting rods makes the movement between the first and second limiting clips more stable, improving the stability of the squeegee when scraping ink.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents use gears and limit clips to fix the squeegee of the printing press to the squeegee fixing plate. However, in reality, after prolonged use, gaps may appear in the meshing position of the gears. This can cause the squeegee to wobble after installation, resulting in poor stability after installation. Therefore, there is an urgent need in the field to improve the squeegee for screen printing machines to overcome the shortcomings of the existing technology. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1-6 A squeegee for a screen printing machine includes a squeegee 1 and a mounting plate 2 for mounting the squeegee 1. A snap-fit ​​bracket 3 adapted to the squeegee 1 is fixedly connected to one side of the mounting plate 2. A plurality of limiting rods 4 are provided on one side of the snap-fit ​​bracket 3. A first moving groove 5 adapted to the limiting rods 4 is opened through one side of the snap-fit ​​bracket 3. A plurality of limiting holes 6 adapted to the limiting rods 4 are opened on one side of the squeegee 1. A plurality of second moving grooves 7 communicating with the first moving grooves 5 are also opened in the snap-fit ​​bracket 3. The second moving grooves 7 are slidably connected... An L-shaped extrusion frame 8 is connected to the extrusion frame 8. An extrusion slope 9 is provided on one side of the extrusion frame 8. An extrusion groove 10 adapted to the extrusion frame 8 is provided through the opposite side of the limiting rod 4. An adjusting bolt 11 is provided through and rotatably connected to one end of the snap-fit ​​bracket 3, which passes through several extrusion frames 8. The adjusting bolt 11 is threaded to the lower part of the extrusion frame 8. A limiting nut 12 for limiting is threaded to the side of the adjusting bolt 11. A sliding limiting strip 13 is fixedly connected to the inner wall of the extrusion groove 10. A sliding limiting groove 14 adapted to the sliding limiting strip 13 is provided on the extrusion slope 9.

[0030] In this embodiment, the specific implementation is as follows: When the printing press scraper 1 needs to be installed on the printing press, the mounting plate 2 is fixedly installed at the designated position on the printing press. When the printing press scraper 1 needs to be installed, the printing press scraper 1 is inserted into the clip bracket 3, and the positions of the limiting hole 6 and the limiting rod 4 are aligned. The adjusting bolt 11 is rotated. When the adjusting bolt 11 is rotated, it drives the extrusion frame 8 to move in the second moving groove 7. At the same time, the extrusion inclined surface 9 on the extrusion frame 8 moves in the extrusion groove 10. The extrusion inclined surface 9 extrudes the extrusion groove 10, driving the limiting rod 4 to slide in the first moving groove 5. One end of the limiting rod 4 moves in the direction of the printing press scraper 1, and the other end of the limiting rod 4 is inserted into the limiting hole 6. The adjusting bolt 11 is tightened, and the limiting nut 12 is tightened and reversed. The position of the adjusting bolt 11 is limited and fixed. In practice, multiple limiting rods 4 can be set according to the length of the printing press scraper 1. By rotating one adjusting bolt 11, several limiting rods 4 can be inserted into the limiting hole 6, which facilitates the later installation or replacement of the printing press scraper 1. This ensures the stability of the printing press scraper 1 after installation and facilitates the installation or removal of the printing press scraper 1. When the printing press scraper 1 needs to be removed, the adjusting bolt 11 is rotated in the opposite direction. When the adjusting bolt 11 rotates, it drives the extrusion frame 8 to move in the opposite direction. At this time, due to the snap-fit ​​cooperation between the sliding limiting groove 14 and the sliding limiting strip 13, when the extrusion frame 8 moves, it drives the limiting rod 4 to move away from the printing press scraper 1, so that the printing press scraper 1 can be removed.

[0031] Example 2

[0032] Please see Figure 3 , Figure 4 and Figure 5 This embodiment includes the above embodiment, and further includes: a chamfer 15 is provided at one end of the limiting rod 4 near the printing machine scraper 1, the inner side wall of the limiting hole 6 is adapted to the chamfer 15, an elastic extrusion plate 16 is fixedly connected to the side of the limiting rod 4 near the printing machine scraper 1, the elastic extrusion plate 16 is elastic, and a slot 17 adapted to the elastic extrusion plate 16 is provided on the inner side wall of the snap-fit ​​bracket 3.

[0033] In this embodiment, the printing press scraper 1 will not wobble after one end of the limiting rod 4 is inserted into the limiting hole 6 with a chamfer 15 and the limiting hole 6 being adapted to the chamfer 15. The elastic extrusion plate 16 with elasticity extrudes the side of the printing press scraper 1, improving the stability of the printing press scraper 1 after installation. When the limiting rod 4 moves away from the printing press scraper 1, the elastic extrusion plate 16 moves into the slot 17, which will not obstruct the space in the snap-fit ​​bracket 3. This allows for the installation of printing press scrapers 1 of different thicknesses, improving the applicability of the overall device.

[0034] Example 3

[0035] Please see Figure 1 and Figure 2 This embodiment includes all the above embodiments, and further includes: a mounting hole 18 is provided through the mounting plate 2, the mounting hole 18 is waist-shaped, and an observation port 19 is provided on one side of the snap-fit ​​bracket 3, the position of the observation port 19 is adapted to the limiting hole 6.

[0036] In this embodiment, the mounting plate 2 is installed by passing through the mounting hole 18 at one end of the fastener. The mounting hole 18 is waist-shaped, which allows for fine adjustment of the position of the mounting plate 2, making it convenient for installers to install and debug. The observation port 19 allows for observation of the position of the limiting hole 6, and to check whether the limiting rod 4 is aligned with the limiting hole 6, making it convenient for installers to install the printing press scraper 1.
