Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel cloth production, in particular to a material feeding device and a processing method for grinding wheel cloth production. Background Art

[0002] The emery cloth wheel is a tool used for surface treatment. It can polish and grind parts. It is commonly used in the fields of wood and metal processing. Abrasives are used in the production process of the grinding wheel cloth. The abrasives are fixed on the grinding wheel cloth so that the grinding wheel cloth will continuously expose new abrasives during the grinding process, so that the grinding wheel cloth always maintains a certain sharpness. A feeding device is required in the production process of the abrasive provided to the grinding wheel cloth.

[0003] In the traditional material feeding device for the production of abrasive cloth wheels, the abrasives are transported in sections during use. The warehouse with abrasives is transported to the feeding device through a pipeline, and then transported to the production process of the abrasive cloth wheels through the feeding device. When the material inside the feeding device is discharged, it is necessary to avoid feeding. Feeding and discharging at the same time will lead to uneven material transportation and reduced transportation efficiency. Therefore, we proposed a new material feeding device and processing method for the production of abrasive cloth wheels to improve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a material feeding device and a processing method for producing an abrasive cloth wheel, so as to solve the problems raised in the above-mentioned background technology.

[0006] As a further technical solution of the present invention, the cross section of the discharge valve plate is smaller than the cross section of the discharge pipe, and a clamping structure is formed between the discharge valve plate and the discharge pipe.

[0007] As a further technical solution of the present invention, the cross section of the feed pipe is larger than the cross section of the feed valve plate, and a clamping structure is formed between the feed pipe and the feed valve plate.

[0008] As a further technical solution of the present invention, the cross section of the first rotating rod is smaller than the cross section of the cross frame, and a rotating structure is formed between the first rotating rod and the cross frame.

[0009] As a further technical solution of the present invention, a servo motor is installed at the top of the box cover, and a connecting seat is installed at the bottom of the servo motor, a rotating rod is installed at the bottom of the connecting seat, and an auger is installed at the bottom of the rotating rod, a connecting frame is installed at the top of the outer wall of the rotating rod, and scraping rods are installed on both sides of the connecting frame.

[0010] As a further technical solution of the present invention, two groups of scraper rods are provided, and the two groups of scraper rods are symmetrically distributed about the central axis of the material box and fit the inner wall of the material box.

[0011] As a further technical solution of the present invention, a dust head is installed on the left side of the discharge pipe, and a dust pipe is installed on one side of the dust head, a box is installed on one side of the dust pipe, and placement racks are fixed at the four corners inside the box, and a collection net frame is movably provided on the top of the placement rack.

[0012] As a further technical solution of the present invention, a fan is installed at the bottom end of the box body.

[0013] As a further technical solution of the present invention, the cross section of the collecting net frame is smaller than the cross section of the box body, and a snap-fit ​​structure is formed between the collecting net frame and the box body.

[0014] A method for processing an emery wheel comprises the following steps:

[0015] S1: After a certain amount of material enters the material box, the valve controller starts to drive the discharge valve plate to rotate so that the discharge pipe is opened, and then the feed valve plate inside the feed pipe rotates to close the feed pipe;

[0016] S2: Before the discharge pipe is opened, the servo motor is started to drive the rotating rod to rotate. The rotation of the rotating rod causes the auger to rotate inside the discharge pipe, so that the material inside the material box is evenly transported out through the discharge pipe. At the same time, the scraping rod also rotates to scrape and clean the inner wall of the material box;

[0017] S3: When the material is discharged through the discharge pipe, the fan is started to allow the dust carried by the material to be discharged to be sucked into the collection frame through the dust suction pipe and the dust suction head for collection;

[0018] S4: When the laser distance sensor detects that the amount of material inside the support rod has reached the bottom, the valve controller is activated to drive the discharge valve plate to rotate and close the discharge pipe. When the discharge valve plate rotates and closes, it drives the feed valve plate to rotate to open the feed pipe, allowing the material to then pass through the feed pipe into the material box.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the material feeding device for producing abrasive cloth wheels not only ensures the stability of material input and output, and ensures that the material can be discharged evenly and is not easy to stick to the wall, but also realizes the environmental protection of the device.

[0020] (1) After the materials stored in the feeding device are put into the feeding device, the discharge valve plate can be closed to input the materials. When the discharge valve plate is rotated and closed, the components including the rotating shaft, the second rotating rod, the second bevel gear and the first rotating rod can automatically drive the feed valve plate to rotate inside the feed pipe to open the feed pipe, thereby ensuring that the discharge pipe and the feed pipe are stably maintained in a state of one open and one closed, and one closed and one open, thereby avoiding material blockage caused by the opening of both the discharge pipe and the feed pipe during material transportation, which affects the efficiency of material flow. In addition, due to the arrangement of the above components, the discharge valve plate and the feed valve plate are combined into a whole, and only one power source is needed to open and close the discharge valve plate and the feed valve plate, thereby saving costs.

[0021] (2) When the feeding device discharges the material through the discharge pipe, the servo motor, the scraping rod, the rotating rod and the auger are provided. When the auger discharges the material through the discharge pipe, the auger can rotate inside the discharge pipe to allow the material to be discharged evenly through the discharge pipe. At the same time, the scraping rod can rotate together with the auger to scrape the inner wall of the material box to avoid material adhesion and waste caused by material;

[0022] (3) When the device is in use, the material is discharged through the discharge pipe. When the material is discharged, it will carry a certain amount of dust with it, causing pollution to the environment. By providing components such as a dust suction pipe, a box body, a collection mesh frame and a fan, the dust discharged during the material discharge process can be adsorbed to prevent the dust from being discharged along with the material to pollute the environment, thereby greatly increasing the environmental friendliness of the device.

A first bevel gear 10 is dynamically provided, a first rotating rod 9 is installed at the top of the first bevel gear 10, and the first rotating rod 9 passes through the cross frame 2 and is movably connected to the cross frame 2, a feed valve plate 24 is installed at the top of the first rotating rod 9, a feed pipe 8 is installed at the top of the right side of the material box 3, and the feed pipe 8 and the feed valve plate 24 are movably connected, a conveying pipeline 7 is installed on one side of the feed pipe 8, the cross section of the discharge valve plate 15 is smaller than the cross section of the discharge pipe 14, a clamping structure is formed between the discharge valve plate 15 and the discharge pipe 14, the discharge pipe 14 can be tightly closed, the cross section of the feed pipe 8 is larger than the cross section of the feed valve plate 24, the feed pipe 8 and the feed valve plate 24 form a clamping structure, the feed pipe 8 can be tightly closed, the cross section of the first rotating rod 9 is smaller than the cross section of the cross frame 2, and a rotating structure is formed between the first rotating rod 9 and the cross frame 2, so that the first rotating rod 9 drives the feed valve plate 24 to rotate stably;

[0032] Specifically, Figure 1 and Figure 3As shown, the laser distance sensor 5 monitors the amount of material inside the material box 3. If it is detected that the material inside the material box 3 is exhausted, the signal is transmitted to the control panel. The control panel starts the valve controller 16 to drive the discharge valve plate 15 to rotate so that the discharge pipe 14 is closed. At this time, the shaft 13 also rotates during the rotation of the discharge valve plate 15. The rotation of the shaft 13 drives the second rotating rod 12 to rotate. The rotation of the second rotating rod 12 causes the second bevel gear 11 to rotate. The rotation of the second bevel gear 11 causes the first bevel gear 11 meshing above to rotate. 0 rotates, the first bevel gear 10 rotates, which drives the first rotating rod 9 to rotate. The first rotating rod 9 rotates so that the feed valve plate 24 rotates inside the feed pipe 8 to open the feed pipe 8, so that the material in the warehouse is introduced into the material box 3. After the laser ranging sensor 5 detects that a certain amount of material has been input into the material box 3, the valve controller 16 is started again to drive the discharge valve plate 15 to rotate in the opposite direction. The discharge valve plate 15 rotates in the opposite direction, which makes the feed valve plate 24 rotate in the opposite direction inside the feed pipe 8 to close the material input and continue to transport the material.

[0033] A servo motor 6 is installed at the top of the box cover 4, and a connecting seat 30 is installed at the bottom of the servo motor 6, a rotating rod 27 is installed at the bottom of the connecting seat 30, and a screw dragon 28 is installed at the bottom of the rotating rod 27, a connecting frame 29 is installed at the top of the outer wall of the rotating rod 27, and scraping rods 26 are installed on both sides of the connecting frame 29, and two groups of scraping rods 26 are provided. The two groups of scraping rods 26 are symmetrically distributed about the central axis of the material box 3 and fit the inner wall of the material box 3, so that the scraping of the inner wall of the material box 3 is more comprehensive and the scraping effect is better;

[0034] Specifically, Figure 1 , Figure 2 and Figure 6 As shown, the servo motor 6 is started to drive the rotating rod 27 to rotate. The rotation of the rotating rod 27 causes the auger 28 to rotate inside the discharge pipe 14, so that the material inside the material box 3 can be evenly transported out through the discharge pipe 14. At the same time, when the rotating rod 27 rotates, the scraping rod 26 can be driven by the connecting frame 29 to rotate in contact with the inner wall of the material box 3, and the inner wall of the material box 3 is scraped to prevent material adhesion.

[0035] A dust suction head 18 is installed on the left side of the discharge pipe 14, and a dust suction pipe 17 is installed on one side of the dust suction head 18, and a box 19 is installed on one side of the dust suction pipe 17. A placement rack 22 is fixed at the four corners inside the box 19, and a collection net frame 20 is movably provided on the top of the placement rack 22. A fan 23 is installed at the bottom end of the box 19. The cross section of the collection net frame 20 is smaller than the cross section of the box 19. A snap-fit ​​structure is formed between the collection net frame 20 and the box 19, which is convenient for disassembling and assembling the collection net frame 20 to remove the dust collected inside it.

[0036] Specifically, Figure 1 and Figure 3 As shown, when the material is discharged through the discharge pipe 14, the fan 23 is started. The fan 23 sucks the dust generated when the material is discharged through the discharge pipe 14 into the collecting frame 20 through the dust suction pipe 17 and the dust suction head 18, and collects it, thereby preventing the dust carried by the material from being discharged along with the material. Subsequently, the box body 19 can be opened to take out the collecting frame 20 to remove the dust collected inside it.

[0037] The application also discloses a method for processing an abrasive wheel.

[0038] A method for processing an emery wheel comprises the following steps:

[0039] S1: After a certain amount of material enters the material box 3, the valve controller 16 starts to drive the discharge valve plate 15 to rotate so that the discharge pipe 14 is opened, and then the feed valve plate 24 inside the feed pipe 8 rotates to close the feed pipe 8;

[0040] S2: before the discharge pipe 14 is opened, the servo motor 6 is started to drive the rotating rod 27 to rotate. The rotation of the rotating rod 27 causes the auger 28 to rotate inside the discharge pipe 14, so that the material inside the material box 3 is evenly transported out through the discharge pipe 14. At the same time, the scraping rod 26 also rotates to scrape and clean the inner wall of the material box 3;

[0041] S3: When the material is discharged through the discharge pipe 14, the fan 23 is started to allow the dust carried by the material when it is discharged to be sucked into the collection frame 20 through the dust suction pipe 17 and the dust suction head 18 for collection;

[0042] S4: When the laser distance measuring sensor 5 detects that the amount of material inside the support rod 1 has reached the bottom, the valve controller 16 is activated to drive the discharge valve plate 15 to rotate and close the discharge pipe 14. When the discharge valve plate 15 rotates and closes, it drives the feed valve plate 24 to rotate so that the feed pipe 8 is opened, allowing the material to then pass through the feed pipe 8 into the interior of the material box 3.

[0043] Working principle: When the present invention is in use, after a certain amount of material enters the material box 3, the valve controller 16 starts to drive the discharge valve plate 15 to rotate so that the discharge pipe 14 is opened, and then the feed valve plate 24 inside the feed pipe 8 rotates to close the feed pipe 8. Before the discharge pipe 14 is opened, the servo motor 6 is started to drive the rotating rod 27 to rotate. The rotation of the rotating rod 27 causes the auger 28 to rotate inside the discharge pipe 14, so that the material inside the material box 3 is evenly transported out through the discharge pipe 14. At the same time, the scraper rod 26 also rotates together to scrape and clean the inner wall of the material box 3, and When the material is discharged through the discharge pipe 14, the fan 23 is started to allow the dust carried by the material when it is discharged to be sucked into the collection frame 20 through the dust suction pipe 17 and the dust suction head 18 to be collected to avoid polluting the environment. After that, when the laser ranging sensor 5 detects that the amount of material inside the support rod 1 has reached the bottom, the valve controller 16 is started to drive the discharge valve plate 15 to rotate and close the discharge pipe 14. When the discharge valve plate 15 rotates and closes, it drives the feed valve plate 24 to rotate so that the feed pipe 8 is opened, allowing the material to then pass through the feed pipe 8 into the interior of the material box 3.
