DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] As shown in Figures 1-7 The utility model provides a powder feeding device, which comprises a belt conveyor 1 inclinedly arranged on the ground and a hopper 2 arranged above the downwardly inclined end of the belt conveyor 1, and further comprises: a cleaning brush assembly 3 arranged at the downwardly inclined end of the belt conveyor 1 and adjustable in distance from the belt, used for sweeping off the powder adhered to the belt; a powder collecting cover assembly 4 fixedly arranged at the terminal end of the downwardly inclined end of the belt conveyor 1 and located obliquely below the cleaning brush assembly 3, used for collecting the powder swept off from the belt; a guide chute 5 fixedly arranged at the upwardly inclined end of the belt conveyor 1, and a scraper assembly 6 arranged on the inner wall of the guide chute 5 and abutting against the conveying belt of the belt conveyor 1; and a plurality of arc-shaped cover plates 7 arranged in a linear and close manner and hingedly arranged on the top of the belt conveyor 1.

[0027] In use, the powder material in the hopper 2 falls onto the belt conveyor 1 and is conveyed to a designated position by the belt conveyor 1. Under the shielding effect of the arc-shaped cover plates 7, the powder is difficult to be scattered during the conveying process. When the powder is conveyed to the upwardly inclined end of the belt conveyor 1, it falls into the guide chute 5 and is guided to a designated position under the action of gravity, and meanwhile, the scraper assembly 6 on the guide chute 5 scrapes off the powder adhered to the belt, avoiding the waste of the powder. In addition, the cleaning brush assembly 3 sweeps off the powder on the belt which is not scraped off by the scraper assembly 6, further improving the separation effect between the powder and the belt and ensuring the cleanliness of the belt. The powder swept off by the cleaning brush assembly 3 falls into the powder collecting cover assembly 4 under the action of gravity, and is uniformly collected and reused.

[0028] In an embodiment, the scraper assembly 6 comprises a positioning plate 61 fixedly arranged between the inner walls of the guide chute 5, two insertion rods 62 symmetrically inserted into the positioning plate 61, a scraper 63 fixedly arranged at the top of the two insertion rods 62, a spring 64 movably sleeved on the insertion rod 62 and abutting against the positioning plate 61 at one end and abutting against the scraper 63 at the other end, and the scraper 63 abutting against the conveying belt of the belt conveyor 1.

[0029] Since the scraper 63 will be worn by the belt during long-term use and its length will be shortened, the design is that when the scraper 63 is shortened due to wear, the spring 64 pushes the scraper 63 to move, the insertion of the insertion rod 62 and the positioning plate 61 provides guidance for the moving process of the scraper 63, so that the scraper 63 always abuts against the belt, and the scraping-off effect of the scraper 63 on the attached powder is ensured.

[0030] In an embodiment, the scraper assembly 6 further comprises a guide rod 65 fixedly arranged on the scraper 63 at one end and penetrating the positioning plate 61 at the other end, and a limiting nut 66 threadedly arranged on the guide rod 65 penetrating the positioning plate 61 at one end.

[0031] In this way, the insertion of the guide rod 65 and the positioning plate 61 provides further guidance for the moving process of the scraper 63, and the stability of the moving process of the scraper 63 is ensured, and the limiting nut 66 can prevent the guide rod 65 from being pulled out of the positioning plate 61.

[0032] In an embodiment, the cleaning brush assembly 3 comprises studs 31 fixedly arranged on both sides of the belt conveyor 1, height-limiting nuts 32 threadedly arranged on the studs 31, mounting plates 33 penetrating the studs 31 at both ends and abutting against the top surface of the height-limiting nuts 32, locking nuts 34 threadedly arranged on the studs 31 and abutting against the top surface of the mounting plates 33, and brushes 35 detachably arranged on the mounting plates 33 and abutting against the belt on the belt conveyor 1.

[0033] In this way, by adjusting the height of the height-limiting nuts 32 on the studs 31, the mounting plates 33 are always abutted against the top surface of the height-limiting nuts 32 under the action of gravity, and then the mounting plates 33 are locked on the height-limiting nuts 32 by using the locking nuts 34, so that the height of the mounting plates 33 is adjusted, and when the brushes 35 are worn by the belt, the height of the mounting plates 33 is adjusted to ensure that the brushes 35 are always abutted against the belt, thereby ensuring the sweeping-off effect of the residual powder on the belt.

[0034] In an embodiment, the powder collecting cover assembly 4 comprises a cover body 41 fixedly arranged on the belt conveyor 1 and having an opening facing the cleaning brush assembly 3, a supporting plate 42 fixedly arranged at the opening end of the bottom of the cover body 41, and an insertion plate 43 movably inserted into the supporting plate 42 and used for plugging the opening at the bottom of the cover body 41.

[0035] In this way, by inserting the insertion plate 43 into the supporting plate 42, the opening end at the bottom of the cover body 41 can be plugged, and the powder swept off by the cleaning brush assembly 3 can be collected by the cover body 41, when the powder in the cover body 41 accumulates to a certain amount, a container is placed at the opening end at the bottom of the cover body 41, and then the insertion plate 43 is pulled out of the supporting plate 42, and the powder in the cover body 41 falls into the container under the action of gravity, thereby completing the recycling and facilitating the secondary use.

[0036] In an embodiment, the arc-shaped cover plate 7 is made of transparent material, and the outer surface is fixedly provided with a handle 8.

[0037] In this way, the arc-shaped cover plate 7 can be easily flipped by the handle 8, facilitating various operations on the belt or belt conveyor 1. By setting the arc-shaped cover plate 7 to be transparent, the user can easily observe the conveying state of the powder on the belt conveyor 1 in real time, improving the convenience of use.

[0038] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0039] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications will also change accordingly.

[0040] In addition, "a plurality of" means two or more. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection required by the present application.
