[0046] Working principle:

[0047] The driving source 21 is started to drive the threaded rod 22 to rotate, so that the threaded sleeve 23 slides, and the two cross bars 31 slide, so that the first telescopic members 32 slide, and the two clamping rods 33 slide. When sliding, the two clamping rods 33 enter the two clamping grooves one by one, so that a glue storage plate 6 and a film transfer plate 7 move synchronously. When moving, the two cross bars 31 contact the two arc blocks 411 respectively, so that the two arc blocks 411 shrink into the chamber, and drive the two racks 410 to move, so that the two connecting plates 49 move, and drive the two second telescopic members 48 to shrink. When the two racks 410 move, they drive the two first gears 47 to rotate, so that the two rotating shafts 46 rotate, and drive the two baffles 45 to rotate and open. , so that the baffle 45 no longer limits the gel storage plate 6 or the transfer plate 7, and then the gel storage plate 6 contacts the scraper 83 when it moves, and the scraper 83 is close to the surface of the gel storage plate 6 where the protein gel is placed to scrape the protein gel, and the protein gel falls on the prepared film on the transfer plate 7 after being scraped off, and at the same time, the scraped part of the protein gel contacts the roller 82, and when the driving source 21 rotates, it drives the second gear 24 to rotate, so that the third gear 25 rotates, drives the rotating shaft to rotate, so that the first bevel gear 27 rotates, drives the second bevel gear 210 to rotate, and drives a fourth gear 29 to rotate, drives the chain to rotate, so that a plurality of fourth bevel gears rotate synchronously, drives a plurality of connecting shafts 211 to rotate, and causes a plurality of rollers 82 to start rotating at the same time, and by setting the second gear 2 4 and the third gear 25, so that the rolling rotation will not tear the protein gel, and the bubbles between the protein gel and the membrane are fully discharged by squeezing the protein gel by the roller 82. After the film is transferred, the glue storage plate 6 and the film transfer plate 7 continue to move and contact the two inclined blocks 553 one by one, respectively, so that the two inclined blocks 553 move, driving the third telescopic member 551 to contract, and then the glue storage plate 6 and the film transfer plate 7 continue to move until they enter the two unloading boxes 5 one by one respectively. When the glue storage plate 6 and the film transfer plate 7 completely enter the two unloading boxes 5, the two third telescopic members 551 are released, so that the two inclined blocks 553 move downward to limit the glue storage plate 6 and the film transfer plate 7, and then the driving source 21 reverses to drive the two cross bars 31 to slide, so that the two clamping rods 33 move in The two sides of the arc block are arranged in an arc shape, so that the arc block does not affect the movement of the cross bar 31. When the clamping rod 33 moves to no longer contact the glue storage plate 6 and the film transfer plate 7, the film transfer plate 7 falls under the action of gravity. The fourth telescopic member 561 and the sponge pad 563 are used for shock absorption, so that the film transfer plate 7 is successfully collected after the film transfer is completed. At the same time, a plastic inclined surface is set on one side of the glue storage plate 6, so that when the next glue storage plate 6 is about to enter the unloading box 5, it will contact the inclined surface of the previous glue storage plate 6, so that the previous glue storage plate 6 is lifted up, so that the travel path of the next glue storage plate 6 will not be affected. When the two clamping rods 33 move to contact the glue storage plates 6 and the film transfer plates 7 in the two loading boxes 4 respectively, by setting one side of the clamping rod 33 as an arc surface,The clamping rod 33 is compressed and retracted into the cross bar 31, so that the first telescopic parts 32 are compressed until the two clamping rods 33 are no longer in contact with the storage plastic plate 6 and the film transfer plate 7 in the two loading boxes 4. Then, the first telescopic parts 32 are released, so that the two clamping rods 33 are reset, so that the whole device is reset and the next film transfer can be carried out quickly.
