Detailed Description

A device is scraped to silk screen printing pair, wherein: including base 1, supporting seat 2, base 1 is the cylinder structure, base 1 internally mounted has driving motor 101, base 1 upper surface evenly is provided with product location groove 102, base 1 top is provided with silk screen frame 3, silk screen frame 3 is the circular structure, silk screen frame 3 edge is provided with guide block 301, silk screen frame 3 with the position department that product location groove 102 corresponds is provided with silk screen printing plate 302, silk screen printing plate 302 can inlay in silk screen frame 3 inside, supporting seat 2 is located the top of the two devices of scraping of silk screen printing, supporting seat 2 fixed mounting has pneumatic cylinder 201, pneumatic cylinder 201 below is connected with movable rod 202, movable rod 202 is fixed with go-between 203 at the farthest end, go-between 203 is rotationally fixed with scraper device 4 and silk screen frame 3 through slide rail 204, go-between 203 can make scraper device 4 and silk screen frame 3 be in the up-and-down motion under the effect of pneumatic cylinder 201, the driving motor 101 can rotate the scraper device 4 under the action of the driven disc 103, a first guide ring 205 and a second guide ring 206 are arranged on the outer side and the inner side of the supporting seat 2, the first guide ring 205 is matched with the first guide block 301, and the second guide ring 206 is matched with the scraper device 4.

Specifically, the scraper device 4 includes a rotating disk 401, a scraper 402 is uniformly arranged outside the rotating disk 401, the scraper 402 is matched with the position of the silk-screen plate 302, a second guide block 403 is uniformly arranged on the upper side of the rotating disk 401, the second guide block 403 is matched with the second guide ring 206, a driving groove 404 is arranged below the rotating disk 401, and the driven disk 103 is matched with the driving groove 404 to drive the scraper device 4 to rotate.

Specifically, the first guide ring 205 and the first guide block 301 are both arc-shaped structures, when the first guide ring 205 and the first guide block 301 are extruded up and down, the first guide ring 205 and the second guide block 403 can rotate relatively, when the first guide ring 206 and the second guide block 403 are extruded up and down, the second guide ring 403 and the second guide block 206 can rotate relatively, and the driving distance between the second guide ring 206 and the second guide block 403 is smaller than the driving distance between the first guide ring 205 and the first guide block 301, so that when the screen printing frame 3 and the scraper device 4 move up, the rotation amount of the scraper device 4 is smaller than the rotation amount of the screen printing frame 3, so that the scraper device 4 and the screen printing frame 3 can rotate relatively, and the scraper 402 scrapes ink back to the original position.

Specifically, the screen printing frame 3 and the base 1 are respectively provided with a convex block 103 and a groove 104 for positioning, so that the screen printing frame 3 and the base 1 are prevented from rotating relatively when the scraper 402 works.

The working principle is as follows: when the silk-screen printing device works, a product to be processed is placed in the product positioning groove 102, the scraper device 4 and the silk-screen frame 3 are pushed downwards by the hydraulic cylinder 201 through the movable rod 202, when the silk-screen printing device is pushed to the position of the base 1, the silk-screen frame 3 and the base 1 are relatively limited under the action of the bump 104 and the groove 105, meanwhile, the silk-screen frame 3 can rotate for a part of distance under the action of the bump 104 and the groove 105, the guide ring II 206 is matched with the guide block II 406 in the later stage, the silk-screen plate 302 and the product positioning groove 102 tightly fix the product, meanwhile, the driven disc 103 is matched with the driving groove 404 below the scraper device 4, at the moment, the driving motor 101 is started, the driven disc 103 drives the scraper device 4 to rotate through the driving groove 404, and the scraper 402 and the silk-screen plate 302 perform first silk-screen printing on the product.

After the first time, the hydraulic cylinder 201 pulls the scraper device 4 and the screen printing frame 3 upwards through the movable rod 202, when the scraper device is pulled to a certain position, the first guide ring 205 is in matched contact with the first guide block 301, the second guide ring 206 is not in contact with the second guide block 403, at this time, under the action of the hydraulic cylinder 201, the screen printing frame 3 also rotates while rising, the scraper device 4 does not rotate, at this time, the relative positions of the scraper device 4 and the screen printing frame 3 change, the scraper 402 of the scraper device 4 scrapes the ink on one side of the scraper 402 in the screen printing frame 3 back to the working end, then the second guide ring 206 is in contact with the second guide block 403 to drive the scraper device 4 and the first screen printing frame 3 to rotate together, at this time, the screen printing frame for the first time rotates 90 degrees, and the screen printing frame for the next process also rotates 90 degrees to the position above the product which has finished the first time, at this moment, the hydraulic cylinder 201 drives the screen printing frame 3 and the scraper device 4 to move downwards, the second screen printing is finally completed on the product, and then the product is taken out, so that the screen printing double-scraping operation on the product is completed.

Meanwhile, multiple groups of products can be arranged for carrying out screen printing and double scraping simultaneously, the working efficiency is greatly improved, the arc angle between the first guide ring 205 and the first guide block 301 is large enough to enable the first guide ring and the first guide block to rotate mutually, and the arc angle between the second guide ring 206 and the second guide block 403 is large enough to enable the second guide ring and the second guide block to rotate mutually.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
