DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 7 A powder scraper with a cleaning function comprises a scraper 1, which comprises a scraper base 10 fixedly connected to a transmission chain inside the scraper 1, a scraper body 11 is rotatably connected to the upper end of the scraper base 10, a screw rod 12 is arranged on the inner side surface of one side panel of the scraper 1, a sliding rod is fixedly connected to the inner side surface of the other side panel of the scraper 1, a shielding mechanism 2 is slidably connected to the upper end of the scraper 1, and a cleaning mechanism 3 is arranged at one end of the shielding mechanism 2.

[0026] The shielding mechanism 2 realizes the action of avoiding the blockage of the powder inside the scraper 1 .

[0027] The cleaning mechanism 3 realizes the action of cleaning the powder inside the scraper conveyor 1 .

[0028] In this embodiment, the shielding mechanism 2 includes a plurality of shielding plates 20 that slide against each other, and the lower surface of one end of the shielding plate 20 is fixedly connected to the upper end of the screw nut of the screw 12 and the surface of the sliding rod, respectively. An adsorption hole 21 is provided at the axial symmetry of one of the shielding plates 20, and a negative pressure adsorption tube 22 is fixedly connected to the hole wall of the adsorption hole 21. The plate bodies of the other shielding plates 20 are all provided with a slide groove, and the groove surface of the slide groove is slidably connected to a slide plate 23 that matches therewith; one end of the slide plate 23 is provided with a The lower end of the shielding plate 20 is located on both sides of the slide groove and has a limit groove 24. One end of the shielding plate 20 with the adsorption hole 21 is rotatably connected to a connecting rod 25, and the surface of the connecting rod 25 is fixedly connected to one end of the cleaning mechanism 3; the upper surface of each shielding plate 20 is fixedly provided with a block adapted to the groove surface of the limit groove 24, and multiple shielding plates 20 are slidably hung in a stacked manner, and the side surface of the shielding plate 20 at the other end opposite to the shielding plate 20 with the adsorption hole 21 is fixedly connected to the inner side surfaces of the two side plates of the scraper 1;

[0029] Specifically, the design of the plurality of shielding plates 20 sliding against each other allows the staff to adjust the shielding range according to actual needs to adapt to scrapers 1 of different sizes; the setting of the adsorption holes 21 and the negative pressure adsorption tube 22 can generate negative pressure, and when the residual powder in the channel of the scraper 1 is cleaned by the cleaning mechanism 3, the powder flying in the air is adsorbed by the negative pressure adsorption tube 22, thereby achieving the cleaning effect of the channel of the scraper 1;

[0030] At the same time, the shielding plate 20 prevents the powder from leaking during the conveying process. The setting of the limiting groove 24 ensures the stability of the shielding plate 20 during the sliding process and prevents the position of the shielding plate 20 from being offset due to vibration.

[0031] In the present embodiment, a cylinder 31 is fixedly connected to one end of the upper surface of the shielding plate 20 with the adsorption hole 21, and a connecting pipe 32 is rotatably connected to the cylinder rod of the cylinder 31, and the upper end of the connecting pipe 32 is externally connected to the air intake pipe, and a telescopic rod 33 is fixedly connected to the lower end of the connecting pipe 32, and a sealing coating is applied between the rod bodies of the telescopic rod 33, and an injection pipe 34 is fixedly connected to the inner wall of the lower end of the telescopic rod 33, and an electric telescopic rod 35 is fixedly connected to the surface of the connecting pipe 32, and the lower end of the electric telescopic rod 35 is fixedly connected to the lower end surface of the telescopic rod 33, and the air outlet of the injection pipe 34 is opposite to the transmission chain of the scraper 1;

[0032] Specifically, by setting the cylinder 31 and the electric telescopic rod 35, the telescopic rod 33 and the connecting rod 25 rotatably connected to one end of the baffle plate 20, a small range of angle adjustment can be performed in the channel of the scraper 1, so that the powder transportation channel in the scraper 1 can be cleaned even in an uneven state. The setting of the jet pipe 34 can blow up the residual powder in each corner of the powder channel of the scraper 1. The blown powder flies inside the channel and is then adsorbed and discharged by the negative pressure adsorption tube 22, thereby completing the cleaning effect of the inside of the powder channel.

[0033] The rotating groove opened at the upper end of the scraper base 10 faces the discharge port of the scraper machine 1. With the above arrangement, before cleaning the inside of the powder channel of the scraper machine 1, the telescopic rod 33 is driven by the electric telescopic rod 35 to descend into the powder channel, so that the scraper body 11 can be tilted under the touch of the jet pipe 34, thereby realizing that the cleaning mechanism 3 can move smoothly in the powder channel.

[0034] The side surfaces of the slide plate 23 and the surface of the negative pressure adsorption tube 22 are both provided with S-level and N-level relative magnets, and the suction force between the magnets is greater than the friction force between the surface of the slide plate 23 and the baffle plate 20; the arrangement of the magnets facilitates the moving negative pressure adsorption tube 22 to drive the slide plate 23 to slide back and forth in the baffle plate 20, and at the same time, the suction force between the magnets is greater than the friction force between the slide plate 23 and the baffle plate 20 and the resistance of the limit groove 24 to the block fixedly connected to the upper end of the baffle plate 20, and the surface of the negative pressure adsorption tube 22 and the slide plate 23 release the adsorption action.

[0035] Operation principle: When in use, the electric telescopic rod 35 drives the telescopic rod 33 to descend into the powder conveying channel of the scraper 1, and the cylinder rod of the cylinder 31 moves back and forth, adjusting the air outlet of the jet pipe 34 to be relative to the position of the conveying chain of the scraper 1, and then the negative pressure adsorption tube 22 and the jet pipe 34 work at the same time, and the gas sprayed by the jet pipe 34 makes the powder inside the channel fly in the powder channel, and the baffle plate 20 located above the channel blocks the flying powder, and the negative pressure adsorption tube 22 absorbs the flying powder in the channel at the same time, and the screw 12 moves slowly, driving the baffle plate 20 and the cleaning mechanism 3 fixedly connected with its screw nut to move toward the side of the discharge port of the scraper 1;

[0036] When the surface of the negative pressure adsorption tube 22 contacts the side of the slide plate 23, the two are attracted to each other and push the slide plate 23 to move toward the other end of the shielding plate 20 where it is located, until the negative pressure adsorption tube 22 reaches the axially symmetrical position of the shielding plate 20, and the block fixed on the upper surface of the shielding plate 20 is also located at the end of the limit groove 24. At this time, the other shielding plate 20 moves toward the discharge port of the scraper 1 under the action of the block;

[0037] When the cleaning mechanism 3 moves inside the channel, the air pressure generated by the air jet 34 directly pushes the scraper body 11, so that the scraper body 11 and the bottom wall of the channel are parallel to each other. When the cleaning mechanism 3 moves to the vicinity of the discharge port of the scraper 1 and cannot move any further, the motor of the scraper 1 works in the reverse direction, and drives the scraper base 10 and the scraper body 11 to move in the reverse direction through the transmission chain inside the scraper 1. At this time, the air jet 34 in the stationary state pushes the scraper body 11 that moves in the reverse direction and enters the channel of the scraper 1. The vibration generated by the tilting of the scraper body 11 drives part of the powder to diffuse inside the channel, and the negative pressure adsorption tube 22 continuously adsorbs the powder inside the channel, further improving the cleaning effect.

[0038] When the scraper 1 is working, it is only necessary to start the motor normally to drive the transmission chain to move. The transmission chain of the scraper 1 makes a circular motion. When the scraper body 11 pushes the powder to move normally, the scraper body 11 is perpendicular to the horizontal scraper 1 before entering the powder channel of the scraper 1. Finally, the scraper body 11 enters the powder channel vertically.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
