Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 2-5, the utility model provides a scraper dismouting device among tin cream printing technology, scraper dismouting device includes at least: two top fixing pieces 1, two scraper fixing pieces 2 and a positioning pin 3; the top fixing piece 1 is provided with a notch 4 and a through hole 5 penetrating from the side to the notch 4; the scraper fixing pieces 2 are positioned on the top surfaces of the scrapers 9, clamping grooves 6 are formed in the scraper fixing pieces 2, and the scraper fixing pieces 2 are embedded in the notches 4 in a one-to-one correspondence manner; the head of the positioning pin 3 penetrates through the through hole 5 to the clamping groove 6, and the scraper 9 is installed; the head of the positioning pin 3 is withdrawn from the clamping groove 6, and the scraper 9 is disassembled.
As an example, as shown in fig. 3, the through hole 5 includes a first through hole 501 and a second through hole 502, the positioning pin 3 includes a primary positioning elastic pin 301 and a reinforcing positioning pin 302, the primary positioning elastic pin 301 is disposed in the first through hole 501, and the head of the primary positioning elastic pin extends out of the first through hole 501, and the reinforcing positioning pin 302 is movably disposed in the second through hole 502. It should be noted that the primary positioning elastic pin 301 can be fixed in the first through hole 501 for a long time, and does not need to be removed from the first through hole 501 of the top fixing member 1 after the scraper 9 is removed. After the scraper 9 is installed and embedded in the notch 4, the primary positioning elastic pin 301 can preliminarily fix the scraper 9; when the scraper 9 needs to be detached, the reinforced positioning pin 302 is unscrewed and withdrawn, the primary positioning elastic pin 301 can also play a certain lifting role on the scraper 9, so that the scraper 9 is prevented from dropping suddenly, and the safety performance is improved. Because the primary positioning elastic pin 301 has a telescopic characteristic, the primary fixing operation of the scraper 9 is more convenient and easier, and only the scraper fixing member 2 needs to be slightly pushed.
Further, the initial positioning elastic pin 301 is an initial positioning snap spring. Of course, the primary positioning elastic pin 301 may have other suitable elastic structures, and is not limited herein. In this embodiment, the initial positioning elastic pin 301 is selected as an initial positioning snap spring.
For example, in order to fix two positioning pins more firmly, the primary positioning elastic pin 301 and the reinforcing positioning pin 302 are respectively corresponding to the respective locking grooves 6 in the scraper fixing member 2. Specifically, the card slot 6 includes a first card slot 601 and a second card slot 602, and after the scraper 9 is installed, the head of the primary positioning elastic pin 301 is embedded in the first card slot 601, and the head of the reinforcing positioning pin 302 is embedded in the second card slot 602. According to the positioning effect of the initial positioning elastic pin 301 and the reinforcing positioning pin 302 in different degrees, the depth of the first slot 601 is smaller than that of the second slot 602.
As an example, a micro sliding groove (not shown) is formed beside the first card slot 601, and when the scraper 9 is installed, the primary positioning elastic pin 301 slides along the micro sliding groove and is embedded into the first card slot 601. The micro sliding groove 601 is convenient for the entering and the limiting of the initial positioning elastic pin 301, so that the scraper 9 is preliminarily connected and fixed.
By way of example, the surface of the reinforcing dowel 302 has a thread structure 3021, which is screwed with the internal thread of the second through hole 502. Specifically, the reinforced positioning pin 302 can control the front end socket through reverse plug-pull rotation, so that the upper and lower mechanisms (the top fixing member 1 and the scraper fixing member 2) of the scraper 9 are firmly fixed together.
By way of example, a connecting piece 10 is also arranged between two top fixing pieces 1. The connecting piece 10 can connect two top fixing pieces 1 into a whole, so that the installation is more convenient, and the installation can be realized only by corresponding positions.
As an example, as shown in fig. 3 to 5, the edge of the notch 4 has a chamfer 7, and the chamfer 7 has a guiding function, so that the scraper fixing member 2 can be assembled and disassembled conveniently, and reverse assembly and mixed assembly can be avoided.
Further, the shape of the scraper fixing part 2 is wide at the top and narrow at the bottom, so that the scraper fixing part 2 is embedded into the notch 4, the scraper 9 is not easy to drop, and safety is guaranteed.
In summary, the scraper mounting and dismounting process of the scraper mounting and dismounting device of the embodiment is as follows:
1) The scraper fixing pieces 2 correspond to the notches 4 of the top fixing piece 1 one by one, and the scraper fixing pieces 2 are slightly pushed, so that the primary positioning elastic pins 302 enter the first clamping grooves 601 of the scraper fixing pieces 2;
2) Rotating the reinforced positioning pin 302 to insert the head part of the reinforced positioning pin 302 into the second slot 602, so as to firmly mount the scraper 9 on the printing machine, as shown in fig. 5, which is a schematic view of the top fixing member 1 and the scraper fixing member 2 being mounted together;
3) When the scraper 9 needs to be replaced, the reinforced positioning pin 302 is rotated in the opposite direction, so that the head bolt of the reinforced positioning pin 302 exits from the second clamping groove 602;
4) The primary positioning elastic pin 301 is withdrawn from the scraper positioning piece 2, so that the scraper 9 is disassembled, and the next step of replacement can be carried out.
The utility model discloses improve the structure that the installation was dismantled and carry out the mechanical design transformation again on scraper basis around original factory is from the area, carry out dimensional data's change again, can not lead to the installation failure like this, guarantee the installation quality.
To sum up, the utility model provides a scraper dismouting device among tin cream printing technology, scraper dismouting device includes at least: two top fixing pieces, two scraper fixing pieces and a positioning pin; the top fixing piece is provided with a notch and a through hole penetrating from the side surface to the notch; the scraper fixing pieces are positioned on the top surfaces of the scrapers, clamping grooves are formed in the scraper fixing pieces, and the scraper fixing pieces are embedded in the notches in a one-to-one correspondence manner; the head of the positioning pin penetrates through the through hole to the clamping groove, and the scraper is installed; the head of the positioning pin is withdrawn from the clamping groove, so that the scraper is disassembled.
