AI Technical Summary
In traditional screen printing, the handheld scraper is prone to tilt and causes ink to leak out, which requires multiple scrapings. The front end of the scraper is uneven after use for a long time, resulting in uneven scraping.
A scraper for screen printing is designed, including a screen printing frame, a first scraper, a curved plate, an auxiliary assembly and an adjustment assembly. Through the coordination of the limit design and the arc-shaped plate, ensure that the ink is evenly distributed and prevent leakage; the second scraper is secondary scraped by the spring action to avoid ink leakage caused by the scraper wear.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of screen printing, in particular to a scraper for screen printing. Background Art
[0002] Screen printing refers to the use of a silk screen as a base, and through the photosensitive platemaking method, to make a screen printing plate with images. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. It uses the basic principle that the mesh holes of the graphic part of the screen printing plate can pass the ink, while the mesh holes of the non-graphic part cannot pass the ink. It can be printed on most materials and can perform curved surface printing.
[0003] Traditional screen printing generally uses a handheld scraper to scrape the ink onto the surface of the object to be printed. However, due to the manual operation of the scraper, the ink is likely to leak out from one side, resulting in a reduction in the ink in front of the scraper, so multiple scrapings are required. In addition, during the scraping process, the front end of the scraper is uneven after long-term use, resulting in uneven scraping. In order to solve the above problems, a screen printing scraper is urgently needed to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the problem that traditional screen printing generally uses a hand-held scraper to scrape ink on the surface of an object to be printed, but the scraper is prone to a certain inclination during manual operation, so that the ink is easy to leak from one side, resulting in a reduction of ink in front of the scraper, so that multiple scraping operations are required, and in the scraping process, the front end of the scraper is uneven after long-term use, resulting in uneven scraping. A screen printing scraper is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a scraper for screen printing, including a screen printing frame, a first scraper is arranged in the screen printing frame, both ends of the first scraper are fixedly connected with arc plates, an auxiliary component is arranged on one side of the first scraper, the top of the first scraper is fixedly connected with a connecting plate, the connecting plate is rotatably connected with a long bolt through a through hole opened therein, the outer wall of the long bolt is fixedly connected with a fixing ring, one end of the long bolt is threadedly connected with a mounting seat, and an adjustment component is arranged in the mounting seat.
[0006] As a further description of the above technical solution:
[0007] The adjustment assembly comprises a mounting sleeve, a connecting rod is slidably connected inside the mounting sleeve, a spring pin is provided on the outer wall of the connecting rod, and the spring pin is slidably connected to the mounting sleeve through a through hole provided on the outer wall of the mounting sleeve.
[0008] As a further description of the above technical solution:
[0009] One end of the connecting rod is fixedly connected to a first limiting seat, the first limiting seat is fixedly connected to a first spring via a groove provided therein, and the other end of the first spring is fixedly connected to a second limiting seat.
[0010] As a further description of the above technical solution:
[0011] The second limiting seat is slidably connected to the first limiting seat through a groove provided therein, and both the first limiting seat and the second limiting seat are located above the frame of the silk-screen frame.
[0012] As a further description of the above technical solution:
[0013] The auxiliary component comprises a support seat, a slide bar is fixedly connected to the bottom end of the support seat, a second spring is arranged on the outer wall of the slide bar, and one end of the second spring is fixedly connected to the support seat.
[0014] As a further description of the above technical solution:
[0015] The outer wall of the slide rod is slidably connected with a second scraper, the other end of the second spring is fixedly connected to the second scraper, and one end of the support seat is fixedly connected to the first scraper.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0017] 1. In the utility model, a first limiting seat is provided inside. When scraping, the spring pin is pressed to separate it from the mounting sleeve, thereby pulling the first limiting seat so that it can contact the top ends of the two side frames of the silk screen frame, and the long bolt is rotated to make the bottom end of the first scraper contact the bottom end of the silk screen frame. Through this design, the first scraper is limited so that it can be perpendicular to the silk screen frame frames on both sides, so that the ink can be evenly distributed in front of the first scraper to prevent it from leaking from one side, and the ink in front of the first scraper is blocked by the arc plate to prevent it from leaking from both sides of the first scraper, thereby reducing its impact on printing.
[0018] 2. In the utility model, a second scraper is provided inside. When the first scraper is scraping, the second scraper generates a force on it through the second spring so that it is in close contact with the bottom end of the screen printing frame, so that it performs a second scraping after the first scraper has scraped. Through this design, it is achieved that the second scraper is scraped by the second scraper after the first scraper has scraped, thereby avoiding the first scraper from leaking ink due to wear at the top end after long-term use, thereby improving the efficiency of screen printing and ensuring the quality of screen printing.
