The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The "front end" and "rear end" of the inflatable bladder 30 are defined according to the sequence of the flow of the fluid in the printing paste wet roller mill.

The present invention "an inflatable balloon 30 constrained to a stent 20" means that the movement of the inflatable balloon is constrained by the stent 20, e.g., blocked by the stent 20, secured directly to the stent 20, etc.

As shown in fig. 1-2, the present embodiment provides a wet roller mill for printing paste, comprising a frame 10 having two side plates 101, two grinding rollers 20 horizontally arranged and installed between the two side plates 101 through bearings, two motors 30 for driving the corresponding grinding rollers 20 to rotate in opposite directions, and a material receiving trough 40 arranged right below a slit between the two grinding rollers 20; the grinding roll scraping device further comprises a scraping assembly which is arranged below the two grinding rolls 20 respectively, and the scraping assembly comprises a mounting plate 501 which is mounted on the side plate 101 and a silica gel scraping strip 502 which is fixed at the upper end of the mounting plate 501; each silica gel scraping strip 502 is abutted against the lower curved surface of the corresponding grinding roll 20; the lower end of each mounting plate 501 is positioned right above the notch of the material receiving groove 40, and a gap is reserved between the lower ends of the two mounting plates 501.

The installation structure of the grinding rollers 20 and the side plates 101 and the power supply mode of the motor 30 are the prior art, the slit between the two grinding rollers 20 can be adjusted according to the fineness of the ground mucilage, and the utility model does not relate to the improvement of adjusting the slit distance between the grinding rollers 20, so the details are not repeated.

Because the grinding roller 20 is arranged horizontally by taking the cross section of the horizontal shaft as a decomposition, the peripheral surface below the cross section of the horizontal shaft is a lower curved surface, when the motor 30 works, the roller is rotated, the definition of the lower peripheral surface is opposite at the moment, namely the peripheral surface below the cross section of the horizontal shaft is the lower peripheral surface by taking a certain time node as a reference, and when the curved surface rotates to the position above the cross section of the horizontal shaft along with the grinding roller 20, the curved surface is changed into the upper curved surface at the moment.

The working principle is as follows: the starting motor 30, two motors 30 drive two grinding roller 20 antiport respectively, inject the printing mucilage into the slit department between two grinding roller 20, two grinding roller 20 carry out the roller to the solid particle in the printing mucilage of slit department, after the granularity of solid particle reaches the requirement in the printing mucilage, solid particle passes through the slit along with the mucilage, because printing mucilage viscosity is great, easy adhesion is in grinding roller 20 outer peripheral face, scrape the mucilage of global under grinding roller 20 through the silica gel strand strip that utilizes global to offset under grinding roller 20, the mucilage of being scraped is scraped the enrichment of strip 502 department at silica gel, flow through mounting panel 501 entering in receiving groove 40 under the action of gravity.

It should be noted that the stress between the silicone rubber scraper strip 502 and the grinding roller 20 is determined according to the viscosity of the printing paste scraped and the elastic coefficient of the silicone rubber scraper strip 502, and is a common knowledge and not a fixed value for those skilled in the art, and will not be described herein again.

In order to adjust the deformation degree of the silica gel scraper bar 502, the side plate 101 is provided with a sliding groove 1011 matched with the mounting plate 501, the mounting plate 501 can slide relative to the sliding groove 1011, and the silica gel scraper bar further comprises a screw hole penetrating through the inner wall of the sliding groove 1011 and a locking screw 60 matched with the screw hole. Slide in spout 1011 through making mounting panel 501 to the distance between adjustment mounting panel 501 upper end and the grinding roller 20, thereby the extrusion degree of control grinding roller 20, mounting panel 501 to the silica gel strip, thereby adapt to the operation requirement of different viscosity printing mucilage, the afterbody through locking screw 60 fixes mounting panel 501 in spout 1011, easy operation is swift. The locking screw 60 can be locked by two locking screws 60 of the two side plates 101 in opposite directions, or can be reinforced by a single locking screw 60.

In order to guide the well-rolled printing adhesive cement, the lower ends of the two mounting plates 501 are inclined oppositely.

As shown in fig. 3, two baffles 70 are fixed on the inner surface of each mounting plate 501, the lower ends of the two baffles 70 are located right above the notch of the material receiving groove 40, and a gap is left between the lower ends of the two baffles 70. The printing adhesive cement flows on the inner surface of the mounting plate 501, and in order to prevent the printing adhesive cement from flowing out from two sides of the mounting plate 501, a three-side shielding structure is formed by the baffle 70 and the mounting plate 501.

The inner surface of the mounting plate 501 is the surface of the two mounting plates 501 facing each other.

In order to realize the flow guiding of the printing paste, the lower ends of the two baffles 70 on the same mounting plate 501 are inclined oppositely. The baffle 70 and the mounting plate 501 form a structure with three sides sheltered to guide the well-rolled printing paste, so that the printing paste is enriched right above the notch of the receiving groove 40, and the receiving groove 40 with a smaller notch of the receiving groove 40 is convenient to receive materials.

As shown in FIG. 4, the automatic feeding device further comprises a hopper 80 fixed on the side plate 101, and the discharge port of the hopper 80 is positioned right above the slit between the two grinding rollers 20. The discharge hole of the hopper 80 is a long and thin rectangle, so that accurate feeding of printing adhesive cement is realized.
