DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figures 1 to 3 As shown, a specific embodiment of the present invention discloses a device for cleaning dust on the surface of brick blanks, comprising a first conveying device 100, a second conveying device 200, a first adjusting device 300, a second adjusting device 400, and a cleaning device 500 installed on a frame; the first conveying device and the second conveying device are in the same conveying plane, the first adjusting device 300 is located between the first conveying device 100 and the second conveying device 200, and is used to block the brick blanks from being transferred from the first conveying device to the second conveying device; the second adjusting device 400 is located above the first conveying device 100, so that the brick blanks in the passage are adjusted in the center; the cleaning device 500 is located above the second conveying device 200, and is used to clean and collect dust on the surface of the brick blanks in the passage, and can clean the dust attached to the cleaning brush of the cleaning device.

[0029] The above-mentioned brick surface dust cleaning equipment can realize the positioning adjustment of the brick in all directions to ensure that it falls accurately within the cleaning range, thereby ensuring comprehensive cleaning of the brick; in addition to cleaning the brick, the cleaning device can also clean the dust attached to the cleaning brush of the cleaning device, which can effectively prevent the brick from being contaminated by dust for the second time and improve the overall cleaning quality.

[0030] Furthermore, if Figure 1 , Figure 4 As shown, the first adjustment device 300 includes a first motor 310 and a first roller 320. The first roller is rotatably mounted on the frame, and the end portion is drivingly connected to the output shaft of the first motor. The first roller 320 is located between the conveying rollers of the first conveying device 100 and the second conveying device 200. The side wall of the first roller 320 is fixedly provided with a baffle 321. The first motor drives the first roller to rotate so that the baffle is higher than the conveying plane of the first conveying device and the second conveying device and is used to block the bricks. The bricks moving with the first conveying device are blocked and the end faces can be aligned. The position of the first roller is adjusted by rotating and the placement position of the baffle is changed. When the baffle is swung to an upward position, a protruding portion higher than the first conveying device and the second conveying device can be formed, thereby blocking the bricks passing through. Since the first conveying device can drive the bricks to continue to move until the entire brick is flush with the baffle portion, alignment adjustment in this direction is achieved.

[0031] Furthermore, if Figure 2 As shown, the second adjustment device 400 includes two cylinders 410, the piston rods of the two cylinders face opposite directions, and a push rack 420 is installed at the end of the piston rod of the cylinder 410. The bottom surface of the push rack is arranged close to the roller bar of the first conveying device. The cylinder is used to drive the push rack to move along the length direction of the roller bar of the second adjustment device. When the cylinder drives the push rack to move synchronously in opposite directions, the centering adjustment of the brick blank is achieved; when the brick blank is adjusted into place in the conveying direction, the two push racks are driven by the two cylinders to move, so that the brick blank is transferred and clamped to the middle to achieve centering adjustment, thereby completing the overall alignment adjustment of the brick blank.

[0032] Furthermore, if Figure 4 As shown, the baffle 321 is provided with a strip hole 322 extending along the length direction, and the strip hole passes through the two side walls of the baffle; a plurality of bearings 330 are rotatably installed at the strip hole 322, and the plurality of bearings are evenly spaced along the length direction of the strip hole to form a rolling support surface for assisting the second adjustment device to perform horizontal pushing adjustment on the brick blank; because the brick blank is abutted against the baffle before the adjustment by the second adjustment device, the provided bearing can be used as the contact part for the brick blank to rotate, effectively preventing the side wall of the brick blank from being scratched when the brick blank is pushed and moved, thereby preventing the quality of the product from being affected.

[0033] Furthermore, if Figure 5 , Figure 6 As shown, the cleaning device 500 includes a rolling brush structure 600 and a dust suction structure 700; the rolling brush structure 600 is used to roll and brush the dust on the surface of the brick, so that the dust moves and is lifted up, and the dust suction structure 700 is used to suck, filter and separate the raised dust, so as to achieve effective cleaning of the dust on the surface of the brick.

[0034] Furthermore, the dust collecting structure 700 includes a cover body 710, a dust filter 720, and a pump body 730. Fig. 9 As shown, the bottom of the cover body is open, and a clamping cavity 711 is provided in the cover wall of the cover body 710; a first air pipe 740 is provided at the top of the cover body 710, and the other end of the first air pipe 740 is connected to the air inlet of the dust filter 720, and the air outlet of the dust filter 720 is connected to the air inlet of the pump body 730 through the second air pipe 750; a plurality of first air holes 712 connected to the clamping cavity 711 are provided on the inner wall of the cover body 710; a negative pressure is formed inside the clamping cavity by the pump body, so as to suppress the raised powder The dust is effectively sucked, and the dust enters the dust filter with the air flow and is separated to realize the collection of dust; the roller brush structure 600 includes a brush roller 610 and a second motor 620. The brush roller 610 is rotatably mounted inside the cover body 710, and the bottom of the brush roller protrudes from the bottom opening of the cover body. The brush roller 610 is driven to rotate by the second motor 620 to effectively clean the surface of the brick blank, so that the dust is lifted, which is convenient for the dust suction structure to suck and collect the dust;

[0035] The cover body comprises an arc-shaped cover, and cover plates are installed at both ends of the arc-shaped cover by bolts. A circular hole is provided in the middle of the cover plate, and a first end and a second end are rotatably inserted into the two circular holes, so that the entire brush roller is rotatably installed inside the cover body; a flange is provided at the bottom of the cover plate, which is bent toward a side away from the center of the cover body, and the cover body is mounted on the frame through the flange and fixedly connected by bolts; the structure is detachable, which can facilitate the disassembly and assembly of the internal brush roller and the overall assembly;

[0036] It should be noted that the dust filter is a bag-type dust filter, which is a common dust filtering device, and the pump body is also a common negative pressure device. Both can be purchased and used on the market, so the details will not be elaborated.

[0037] Furthermore, if Figure 7 , Figure 8As shown, the brush roller 610 includes a cylinder 611, and a first end 612 and a second end 613 are respectively installed at both ends of the cylinder; the outer wall of the cylinder 611 is provided with a plurality of second air holes 614 extending in the length direction, and the second air holes are arranged in a circular array around the axis of the cylinder, and are all connected to the inside of the cylinder; the outer wall of the cylinder 611 is provided with a plurality of slots 615, and the slots include but are not limited to dovetail slots or T-slots, and the plurality of slots are arranged in a circular array around the axis of the cylinder, and the slots and the second air holes are arranged at intervals; the two ends of the slots extend through the end of the cylinder, and the slots 615 are used to clamp and install the brush strips 616 , the bristles of the brush strip extend in the direction away from the cylinder; the brush strip 616 is clamped and fixed by the first end 612 and the second end 613; the first end 612 and the second end 613 are rotatably passed through the two ends of the cover body 710, the first end 612 is transmission-connected to the second motor 620, the second end 613 is provided with an air guide pipe 614 connected to the inside of the cylinder 611, and a rotary joint 630 is installed at the end of the air guide pipe 614, and the rotary joint 630 is connected to the air outlet of the pump body 730 through the third air pipe 760; a wind shield 640 is installed inside the cylinder 611, limiting the cylinder to only discharge air at the upper part;

[0038] Since the brush roller will pick up some dust when brushing the surface of the brick blank, the above-mentioned structural design can guide the airflow sent by the pump body to enter the inside of the brush roller and only spray at the top position, so that the dust attached to the brush strip can be quickly detached and detached and collected under the attraction of the dust suction structure; moreover, it will not be sprayed on the brick blank below, and will not cause dust to float around, effectively preventing dust from flying out; the clever use of the pump body's suction and exhaust action can further enhance the dust cleaning and collection effect, and also ensure that the brush roller itself maintains sufficient cleanliness to avoid the problem of secondary pollution of the brick blank; it should be pointed out that the transmission connection between the first motor and the first roller strip and the transmission connection between the second motor and the first end include but are not limited to coupling connection or chain sprocket connection or synchronous belt pulley connection, which can be adjusted accordingly according to the actual layout situation to achieve the required driving rotation action.

[0039] Furthermore, the wind shield 640 includes an arc-shaped groove 641, the outer wall diameter of the arc-shaped groove 641 is adapted to the inner wall diameter of the cylinder 611, and the arc-shaped groove slides against the inner wall of the cylinder; a counterweight strip 642 is installed at the bottom of the inner wall of the arc-shaped groove 641, so that the wind shield is always maintained at the bottom of the cylinder, blocking the second air hole at the bottom of the cylinder, so that the wind shield has a certain weight and will not rotate with the brush roller to maintain the second air hole at the bottom position. It also does not affect the normal operation of the second air hole at the top, thereby meeting the required limitation of only exhausting air at the top, blowing the brush strip to remove the attached dust, and achieving a self-cleaning effect.

[0040] Furthermore, it also includes an infrared sensor for monitoring the movement of the brick blanks into position and an electric control box for overall coordinated operation, coordinating the cooperation of the first conveying device, the second conveying device, the first adjustment device, and the second adjustment device; more specifically, the first adjustment device is first in a blocking position, and the first conveying device drives the brick blanks to move, and the brick blanks are against the blocking bar. Driven by the first conveying device, the brick blanks move to a position flush with the brick blanks to achieve adjustment in this direction; then, the second adjustment device is restarted to adjust the brick blanks to the middle to achieve centering; thereafter, the second adjustment device and the first adjustment device are reset, and the first conveying device drives the brick blanks to the second conveying device, and the second conveying device drives the brick blanks through the cleaning device to clean the dust on the surface of the brick blanks.

[0041] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
