The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.

The embodiment of the utility model provides a coating device, please refer to fig. 1, fig. 2 and fig. 3, which mainly comprises a clamping plate 2, a feeding device 3 and a scraping plate 4, wherein the scraping plate 4 and the clamping plate 2 are respectively arranged at the opposite sides of the feeding device 3; a tube core structure is arranged on the inner side of the clamping plate 2, and a material conveying groove 23 is arranged on the upper side of the tube core structure; the feeding device 3 is provided with a cavity corresponding to the tube core structure, so that the tube core structure can be inserted into the feeding device 3, and the upper end of the feeding device 3 is provided with a feeding hole 31 communicated with the material conveying groove 23; the outer side of the material scraping plate 4 is provided with a material scraping device 6, the front end of the tube core structure is opposite to the material scraping device 6, and the front end of the material conveying groove 23 is positioned behind the material scraping device 6, so that the base body 1 can be scraped with redundant material liquid by the material scraping device 6 after the material liquid falling from the front end of the material conveying groove 23 is loaded.

Two opposite sides of the feeding device 3 are respectively provided with a clamping plate 2 and a scraping plate 4, the inner side of the clamping plate 2 is provided with a tube core structure, and the substrate 1 runs and runs in the tube core structure. An inlet 11 can be arranged on the clamping plate 2 corresponding to the cavity at the tail end of the tube core structure, a scraper 6 is arranged on the scraper plate 4 corresponding to the cavity at the head end of the tube core structure, and a scraper port 61 and the inlet 11 of the scraper 6 can be coaxially arranged, so that the running path of the substrate 1 is limited.

The matrix 1 is a "wire" of a certain diameter, depending on the actual production situation, which is released from the outside of the end of the inlet 11 and collected outside the scraper 61 after the loading load has been completed.

In the embodiment of the utility model, the material conveying groove 23 is arranged on the upper side of the hollow structure, the tail end of the material conveying groove 23 is communicated with the feeding hole 31 on the feeding device 3, and the front end of the material conveying groove 23 is arranged close to the material scraper 6, so that the requirement on the running path of the substrate 1 during material feeding is reduced.

It can be understood that, due to the restriction of the scraping opening 61 of the scraper 6, no matter whether the running path of the substrate 1 deviates or not, the running path will finally point to the scraping opening 61, and when the front end of the material conveying groove 23 is closer to the scraping opening 61, the influence of the path deviation of the substrate 1 on the feeding can be effectively reduced.

Further, the depth and width of the feed delivery groove 23 should be larger than the diameter of the substrate 1, and preferably, the width of the feed delivery groove 23 is at least twice as large as that of the substrate 1, and the depth may be the same as that of the substrate 1. So that the feed liquid can completely infiltrate the substrate 1 when flowing to the foremost end of the feed chute 23 and freely falls.

It will be appreciated that the speed of operation of the substrate 1, the feed rate of the feed port 31, and the like can be adjusted to ensure the wetting effect, as well as the loading effect of the substrate 1 with the feed solution.

In the embodiment of the present invention, the feeding device 3 may be provided with corresponding cavities according to the tube core structure of the clamping plate 2, so that the tube core structure can be inserted into the feeding device 3 and fixed.

The length of the upper conical wall 22 of the tail conical cavity is smaller than that of the lower conical wall 24, so that the backflow cavity enclosed between the lower conical wall 24 and the clamping plate 2 is far larger than the cavity enclosed between the upper conical wall 22 and the clamping plate 2, and the backflow cavity can be used for collecting and collecting feed liquid flowing back into the central tube 21.

It will be appreciated that the chamber between the clamping plate 2 and the lower conical wall 24 below the inlet 11 may be defined as a back-flow chamber.

It can be understood that, based on the splint 2 that is vertically arranged, the rough edge corresponding to the lower conical wall 24 or the upper conical wall 22 is flush at any time at the rough position of the tail cone cavity, so that the rough edge can be completely attached to the splint 2 for fixation. The opening position of the inlet 11 can be opposite to the inner cavity of the central tube 21.

In the embodiment of the present invention, the material conveying groove 23 may extend from the middle of the upper conical wall 22 to the foremost end of the central tube 21, the material feeding device 3 has a material feeding port 31 at a position corresponding to the end of the material conveying groove 23 on the upper conical wall 22, so that the material feeding port 31 and the material conveying groove 23 are in a communicating state, and the liquid material may flow downward along the conical wall, thereby realizing the autonomous transportation of the material liquid, and may fall down until reaching the front end of the material conveying groove 23.

In the embodiment of the present invention, the scraper 6 may have a tapered structure, and the narrow opening of the tapered structure is the scraper opening 61, and the wide opening is the fixing opening 62.

As an embodiment, the conical structure may be designed as an oblique cone, the scraping opening 61 and the fixing opening 62 are not coaxial, the scraping opening 61 is deviated downwards, and the scraping opening 61 is always coaxial with the inlet 11.

The fixed connection port 62 is fixedly connected with the scraper plate 4, the diameter of the fixed connection port 62 can be slightly larger than that of the central tube 21, so that the central tube 21 can extend into a part of structure in the thick opening of the scraper 6 after passing through the scraper plate 4, and the conical wall of the scraper 6 does not generate a blocking effect on the material conveying groove 23.

It will be appreciated that an annular extension may be provided at the fastening port 62 to ensure that the trough 23 is able to deliver a stable feed liquid near the scraping port 61. The free falling feed liquid can be accurately poured onto the substrate 1.

Further, the base body 1 may carry a part of the feed liquid to the outside of the scraping port 61 during operation, and a recovery tank 5 may be provided directly below the scraping port 61 to recover the feed liquid.

Preferably, referring to fig. 1 and 2, a stopper 7 may be disposed on the lower tapered wall of the scraper 6 for stopping, collecting and dropping the liquid flowing down into the recovery tank 5. Specifically, the transverse span of the stop member 7 can be arranged along the lower side of the conical wall and occupies the lower conical wall divided into two parts, and the front end of the middle part of the stop member 7 is inclined downwards to the interior of the recovery tank 5, so that the feed liquid can be automatically converged to the front end of the inclined downwards middle part after being stopped by the stop member 7 with the transverse span and can be dripped into the recovery tank 5.

In the embodiment of the present invention, the traveling path of the base body 1 should be kept horizontal at all times, and when inside the center pipe 21, it may be deviated downward from the axial center line of the center pipe 21, but the base body 1 does not contact the bottom wall of the center pipe 21. It can be understood that the feed liquid flowing back to the backflow cavity can contact the base body 1 when being accumulated to a certain degree, and the operation of the device is stopped at the moment to recycle the feed liquid in the backflow cavity.
