[0016] Beneficial effects:

[0017] During the operation of the conveyor belt, the cleaning brush continuously removes the dirt, dust and metal debris on the parts remaining on the conveyor belt, thereby effectively preventing the accumulation of dirt, dust and metal debris on the conveyor belt and affecting the appearance and quality of the parts. At the same time, the conveyor belt drives the rotation of the rotating roller 2 to control the cleaning brush and the conveyor belt to rotate in the opposite direction, thereby increasing the relative friction between the cleaning brush and the conveyor belt, improving the cleaning efficiency, and at the same time improving the overall performance of the parts product;

[0018] When the dirt, dust and metal debris cleaned by the cleaning brush rotates, they fall into the collection box through the trapezoidal groove. The design of the collection box enables these waste materials to be collected and processed in a centralized manner, avoiding the waste materials from being scattered in the surrounding environment, further reducing the risk of pollution. At the same time, the rotation of the control gear 1 controls the wedge plate 1 to repeatedly squeeze the wedge plate 2 and the cooperation of the plurality of springs 1, so that the collection box is shaken back and forth, so that the dirt, dust and metal debris and other attachments of the cleaned parts can be more evenly distributed in the collection box, thereby making full use of the space inside the collection box;

[0019] The flow control mechanism pushes the piston plate 2 to slide in the air box through the cylinder, changing the air pressure in the air box. The change in air pressure is transmitted to the control chamber through the air hose 1, pushing the piston plate 1 and the baffle plate 1 to move up and down, thereby adjusting the size of the control port of the feed port. The precise control of the air pressure by the cylinder can achieve precise adjustment of the part flow rate, and can accurately control the part material flow rate according to different production requirements, ensuring the stability and accuracy of material supply during the part processing process;

[0020] By driving the motor to control the cam to rotate repeatedly to make the piston plate three move, the air pressure in the control box can be affected, and then through the meshing action of the rack plate and the control gear three, multiple rotating plates are driven to rotate simultaneously, so as to achieve uniform feeding of parts processing materials, ensure that each processing link in the parts processing can get a stable material supply, ensure that the proportion of various raw materials in the parts processing process is accurate, and further improve the quality stability of the product.

[0030] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 8 As shown, the flow control mechanism 2 includes a feed port 201, a drop box 202 is fixedly connected to the upper surface of the conveying box 1 and located on the right side of the feed port 201, and the lower surface of the drop box 202 extends to the top of the conveyor belt 4, a through-type control port 203 is opened at the lower right side of the feed port 201, and a control chamber 204 is integrally formed inside the feed port 201 and located above the control port 203, and a piston plate 205 is slidably connected to the control chamber 204, and the lower surface of the piston plate 205 is fixedly connected to A baffle plate 206 is connected, the lower surface of the baffle plate 206 extends to the bottom of the control chamber 204, the upper surface of the drop box 202 is fixedly connected to the air box 207, the interior of the air box 207 is slidably connected to the piston plate 208, the upper surface of the drop box 202 and located on the right side of the air box 207 is fixedly connected to the cylinder 209, the left end of the output shaft of the cylinder 209 is fixedly connected to the right side of the piston plate 208, and the left side of the interior of the air box 207 and the right side of the interior of the control chamber 204 are fixedly connected to the gas hose 210;

[0033] When the starting cylinder 209 is extended, its output shaft pushes the piston plate 208 to slide in the air box 207. The movement of the piston plate 208 will change the air pressure in the air box 207, and then the air pressure change will be transmitted to the inside of the control chamber 204 through the air hose 210. When the air pressure in the air box 207 increases, it will push the piston plate 205 to slide downward in the control chamber 204, thereby driving the baffle 206 to move downward, reducing the size of the material control port 203, and thereby reducing the flow of parts materials entering the conveyor belt 4 from the material control port 203. Conversely, when the air pressure in the air box 207 decreases, the piston plate 205 moves upward under the action of the cylinder 209, driving the baffle 206 to rise, increasing the size of the material control port 203, and increasing the flow of parts materials. This allows the flow of parts materials to be accurately controlled according to different production requirements, thereby ensuring the stability and accuracy of material supply during part processing.

[0034] like Figure 1 , Figure 2 As shown, an automatic feeder with adjustable flow rate is provided, comprising a conveying box 1, a flow control mechanism 2 is fixedly connected to the left side of the upper surface of the conveying box 1, two rotating rollers 3 are rotatably connected to the inside of the conveying box 1 through a rotating shaft, and the outer side walls of the two rotating rollers 3 are rotatably connected to a conveyor belt 4, a cleaning mechanism 5 is arranged inside the conveying box 1 and below the conveyor belt 4, a feeding port 6 is fixedly connected to the right side of the conveying box 1, a driving motor 7 is fixedly connected to the left side of the front surface of the conveying box 1, and the rear end of the output shaft of the driving motor 7 is fixedly connected to the front surface of the rotating roller 3 located on the left side of the inside of the conveying box 1;

[0035] The conveying box 1 is set as the main frame of the automatic feeding device to provide installation and support for various components. The flow control mechanism 2 can adjust the flow of parts processing materials according to production needs to ensure the accuracy and stability of feeding. The two rotating rollers 3 are driven to rotate by starting the driving motor 7. The conveyor belt 4 is driven by the two rotating rollers 3 to realize the transportation of parts processing materials. During the operation of the conveyor belt 4, the cleaning mechanism 5 continuously cleans it to prevent impurities such as dirt, dust and metal debris from accumulating on the conveyor belt 4, affecting the transportation effect and parts hygiene, and ensuring the quality stability during the parts processing process. Finally, the parts are transported to the designated processing position through the set feeding port 6.

[0036] like Figure 2 As shown, two guide plates 8 are fixedly connected inside the conveying box 1 and above the conveyor belt 4, and the opposite sides of the two guide plates 8 are fixedly connected to the front surface and the rear surface of the interior of the conveying box 1 respectively;

[0037] The two guide plates 8 are provided to conveniently guide the flow direction of the parts processing materials on the conveyor belt 4. During the feeding process, the two guide plates 8 can play a blocking role to ensure that the materials are always transported within the range of the conveyor belt 4, thereby improving the safety and reliability of feeding.

[0038] like Figure 1 As shown, an observation window 18 is integrally formed on the right side of the front surface of the conveying box 1;

[0039] The observation window 18 provides an operator with a channel to directly observe the feeding situation inside the conveying box 1. Through the observation window 18, the operator can understand in real time the flow state of the material on the conveyor belt 4, the flow rate, whether there is blockage or accumulation, etc., thereby helping to discover problems in time and take corresponding measures to ensure the smooth progress of the feeding process.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, the cleaning mechanism 5 includes a rotating column 501, the outer wall of the rotating column 501 is fixedly connected with a cleaning brush 502, the upper part of the outer wall of the cleaning brush 502 is in contact with the lower part of the outer wall of the conveyor belt 4, the conveyor belt 4 is internally located between the two rotating rollers 1 3 and is drivingly connected with a rotating roller 2 503, the front surface of the conveying box 1 and located in front of the rotating roller 2 503 is provided with a turntable 1 504, the center of the rear surface of the turntable 1 504 is fixedly connected with the center of the front surface of the rotating roller 2 503, the front surface of the conveying box 1 and located in front of the rotating column 501 A control gear 1 505 is provided on the side, and the center of the rear surface of the control gear 1 505 is fixedly connected to the center of the front surface of the rotating column 501. The front surface of the conveying box 1 and located above the control gear 1 505 is rotatably connected to a control gear 2 506 through a rotating shaft. The outer wall of the control gear 1 505 is meshed with the outer wall of the control gear 2 506. A turntable 2 507 is fixedly connected to the center of the front surface of the control gear 2 506. The outer wall of the turntable 2 507 and the outer wall of the turntable 1 504 are jointly connected to a transmission belt 508.

[0041] When the conveyor belt 4 is controlled to rotate by the driving motor 7, the conveyor belt 4 will also drive the rotating roller 2 503 to rotate, and the rotating roller 2 503 drives the turntable 1 504 to rotate at the same time. The turntable 1 504 drives the turntable 2 507 and the control gear 2 506 to rotate at the same time through the set turntable 1 504, that is, the control gear 2 506 is engaged with the control gear 1 505, so that the control gear 1 505 rotates in the opposite direction, thereby driving the cleaning brush 502 on the rotating column 501 to rotate in the opposite direction to the conveyor belt 4, so that the cleaning brush 502 can more effectively brush away impurities such as dirt, dust and metal debris on the conveyor belt 4, and the reverse rotation design can increase the relative friction between the cleaning brush 502 and the conveyor belt 4, thereby improving the cleaning efficiency.

[0042] like Figure 1 , Figure 5 and Figure 7 As shown, the front surface of the conveying box 1 is fixedly connected to the top of the driving motor 7 with an extrusion box 10, the interior of the extrusion box 10 is slidably connected with a piston plate 3 11, the lower surface of the piston plate 3 11 is fixedly connected with a contact plate 12, the bottom end of the contact plate 12 extends to the bottom of the extrusion box 10, the outer side wall of the output shaft of the driving motor 7 and located in front of the conveying box 1 is fixedly connected with a cam 13, the upper surface of the piston plate 3 11 and the inner upper surface of the extrusion box 10 are fixedly connected with a plurality of springs 2 14, the left side of the drop box 202 and the interior of the conveying box 1 is fixedly connected with a control box 15, the interior of the control box 15 is slidably connected with a piston plate 4 16, the piston plate 4 16 A rack plate 19 is fixedly connected to the lower surface of the control box 15, and the bottom end of the rack plate 19 extends to the bottom of the control box 15. A gas hose 20 is fixedly connected to the upper left side of the control box 15 and the upper surface of the inner part of the extrusion box 10. A plurality of rotating plates 21 are rotatably connected to the left and right sides of the drop box 202 through a rotating shaft. A plurality of connecting rods 22 are fixedly connected between the plurality of rotating plates 21. A control gear 3 23 is arranged below the control box 15. The right center of the control gear 3 23 is fixedly connected to the left side of the rotating plate 21 located between the inside of the drop box 202, and the outer wall of the control gear 3 23 is meshedly connected to the front surface of the rack plate 19.

[0043] While the driving motor 7 drives the conveyor belt 4 to operate, the cam 13 on its output shaft rotates continuously. When the protruding portion of the cam 13 contacts the bottom end of the contact plate 12, the piston plate 3 11 is pushed to move upward in the extrusion box 10, and the plurality of springs 2 14 are compressed at the same time. When the protruding portion of the cam 13 turns away from the contact plate 12, the elastic force of the plurality of springs 2 14 causes the piston plate 3 11 to move downward, thereby affecting the change of the air pressure in the control box 15. When the piston plate 3 11 in the extrusion box 10 rises, the internal air pressure of the extrusion box 10 increases, and gas is transported to the control box 15 through the gas hose 20, so that the air pressure in the control box 15 increases, thereby pushing the piston plate 4 16 and the rack plate 19 to move downward. When the plug plate three 11 descends, the air pressure in the extrusion box 10 decreases, which can make the piston plate four 16 and the rack plate 19 move upward, so that the rack plate 19 drives the control gear three 23 to continuously rotate forward and reverse during the up and down movement. Since the multiple rotating plates 21 are connected together by multiple connecting rods two 22, when the control gear three 23 rotates to control the rotation of one of the rotating plates 21, the other rotating plates 21 will also rotate synchronously. Therefore, the rotation of the multiple rotating plates 21 can intermittently block and release the parts processing materials, so that the parts processing materials can be evenly dropped onto the conveyor belt 4, so as to achieve the purpose of uniform feeding and ensure that each processing link in the parts processing can get a stable material supply.

[0044] like Figure 1-Figure 4 As shown, a fixed box 509 is fixedly connected to the lower surface of the conveying box 1 and located below the rotating column 501, a through trapezoidal groove 510 is opened on the inner lower surface of the conveying box 1 and located above the fixed box 509, two positioning boxes 511 are fixedly connected to the left and right sides of the fixed box 509, a plurality of positioning boxes 511 are slidably connected to the inside of sliding plates 512, a plurality of sliding plates 512 are fixedly connected to the lower surfaces of the plurality of extending plates 513, a collecting box 514 is fixedly connected to the lower surfaces of the plurality of extending plates 513, a connecting rod 515 is fixedly connected to the left and right sides of the fixed box 509 and located below the collecting box 514, a semicircular block 516 is rotatably connected to the outer wall of the connecting rod 515, and the upper surface of the semicircular block 516 is connected to the collecting box 514 The lower surface of the collecting box 514 is fixedly connected, a through-type sliding vertical groove 517 is provided on the inner front surface, a sliding rod 518 is fixedly connected to the inner upper surface and the lower surface of the sliding vertical groove 517, a sliding block 519 is slidably connected to the outer wall of the sliding rod 518, a wedge plate 520 is fixedly connected to the rear surface of the sliding block 519, a wedge plate 2 521 is fixedly connected to the front surface of the collecting box 514 and located below the wedge plate 1 520, a convex column 522 is fixedly connected to the upper surface of the control gear 1 505 and the front surface of the sliding block 519, and a lifting rod 523 is rotatably connected to the front ends of the two convex columns 522 through a rotating shaft, and the upper surfaces of the plurality of sliding plates 512 are respectively fixedly connected to the inner upper surfaces of the plurality of positioning boxes 511 with a plurality of springs 1 524;

[0045] When the control gear 505 rotates, the boss 522 above its front surface will also rotate accordingly. The boss 522 drives the sliding block 519 to slide up and down on the outside of the sliding rod 518 through the provided lifting rod 523. The sliding block 519 slides up and down, driving the wedge plate 1 520 to move up and down. When the wedge plate 1 520 moves up and down, it will squeeze the wedge plate 2 521, so that the semicircular block 516 under the collection box 514 can rotate on the connecting rod 1 515. At the same time, through the cooperation of the provided multiple protruding plates 513 and the multiple springs 1 524, the collection box 514 can be driven to shake back and forth, so that the impurities such as dirt, dust and metal debris that have been cleaned up can be more evenly distributed in the collection box 514, so that the space inside the collection box 514 can be fully utilized, the production efficiency can be improved, and there is no need to frequently stop the machine to clean up waste, saving time and labor costs.

[0046] like Figure 3 As shown, the rear surface of the fixed box 509 and the rear surface of the collection box 514 are both rotatably connected with a sealing door 17 through hinges;

[0047] When the waste in the collection box 514 accumulates to a certain extent and needs to be cleaned, the two sealed doors 17 make the cleaning work more convenient and quick. The staff can open the two sealed doors 17 and take out the waste in the collection box 514 for processing without disassembling the entire collection box 514, which increases the convenience of using the device.

[0048] like Figure 2 As shown, baffle plates 9 are fixedly connected to the inner lower surface of the conveying box 1 and located on both sides of the trapezoidal groove 510;

[0049] After the cleaning mechanism 5 cleans the conveyor belt 4, the waste will fall into the collection box 514 through the trapezoidal groove 510. The two baffles 9 located on both sides of the trapezoidal groove 510 can guide the waste to fall, ensuring that the waste can accurately fall into the collection box 514 without being scattered to other places, thereby improving the overall performance of the equipment and the quality of the production environment.
