Plate machining device and machining process thereof

Abstract

The invention relates to the technical field of plate machining, and particularly discloses a plate machining device and a machining process thereof.The plate machining device comprises two steel belts rotationally arranged on a rack, and a scraping assembly is arranged on the rack; the scraping assembly comprises a force application plate elastically and rotationally arranged on the rack and a containing box which is in linkage with the force application plate through a linkage mechanism and rotationally arranged on the rack. Under the condition of avoiding waste and pollution caused by dropping of the release agent, the design that the force application plate is ingeniously utilized to drive the containing box to rotate is adopted, so that the release agent collected in the inner cavity of the containing box can be ingeniously transferred to the two sides of the top face of the plywood by the absorption ring in the plywood pushing process; and when the extension parts on the two sides of the plywood are in contact with the surface of the steel belt, the extension parts are more difficult to adhere to the surface of the steel belt, so that the probability that the extension parts on the two sides of the plywood adhere to the two sides of the surface of the steel belt with glue is greatly reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of plate processing, in particular to a plate processing device and a processing technology thereof. Background Art

[0002] Plywood is made of multiple layers of wood veneers bonded together with glue. During processing, glue-coated veneers are typically laid out in a crisscross pattern along the wood grain to form a slab, which is then pressed with or without heating. In existing technology, plywood is typically pressed using a steel belt press.

[0003] When the plywood is squeezed, its two sides will be extended due to its material. The extended part will be weakened due to structural damage, and under the action of glue, it is easy to adhere to the left and right sides of the steel strip surface, thereby contaminating the steel strip. In order to prevent the contamination of the steel strip, the existing technology mostly applies or sprays a release agent on the steel strip. At the same time, since the middle part of the steel strip does not contact the extended parts on both sides of the plywood, in order to save the amount of release agent, it is only necessary to spray the left and right sides of the steel strip surface.

[0004] For example, the existing patent with application number 202311230877.5 and titled "An automatic spraying machine for releasing agent on the edge of steel strip" is equipped with a nozzle for spraying release agent on the steel strip, and the nozzle is connected to the box containing the release agent through a nozzle; it also includes a cleaning component for cleaning the surface of the steel strip, and a collection plate for recovering excess release agent to avoid waste caused by excessive spraying of release agent. Another example is the invention patent with application number 201911331476.2 and titled "A hot press machine for hot pressing steel strips for artificial boards", which discloses a release agent spraying device for spraying a release agent on the steel strip on the active roller; a coating roller located at the lower end of the active roller, which is used to evenly apply the release agent on the steel strip; and a release agent collection tray located below the release agent spraying device, which is used to collect the sprayed excess release agent.

[0005] However, during the actual processing, the applicant discovered that the above-mentioned existing patents and other existing technologies all have at least the following defects: Since the surface of the steel strip itself is smooth, after the release agent is sprayed, the release agent will drip along the steel strip before the steel strip is squeezed into the plywood, resulting in insufficient amount of release agent adhering to the steel strip, and the dripping release agent will contaminate the workbench. In order to avoid waste and pollution caused by dripping of the release agent, in the prior art, after the release agent is sprayed, the excess release agent on the steel strip is scraped off by a scraper or other scraping mechanism. This results in even less release agent on both sides of the steel strip surface, so that when the steel strip is squeezed into the plywood, the extended parts on both sides of the plywood will still adhere to both sides of the steel strip surface with glue with a high probability. Thus, how to avoid waste and pollution caused by dripping of the release agent while reducing the probability of the extended parts on both sides of the plywood adhering to both sides of the steel strip surface with glue is a technical problem that needs to be solved urgently. Summary of the Invention

[0006] The object of the present invention is to provide a sheet metal processing device and a processing technology thereof to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a sheet metal processing device, comprising two steel belts rotatably mounted on a frame, a scraping assembly being mounted on the frame, the scraping assembly comprising a force-applying plate rotatably mounted on the frame, and a receiving box rotatably mounted on the frame and linked to the force-applying plate via a linkage mechanism; A scraper is fixedly mounted on the receiving box, which is in communication with the inner cavity of the receiving box and contacts the outer surface of the corresponding steel strip to scrape off excess release agent on the steel strip. The scraped release agent flows along the scraper into the inner cavity of the receiving box for storage. Two absorption rings are rotatably mounted on the receiving box and are press-fitted with the two sides of the top surface of the plywood in a one-to-one correspondence. Two avoidance openings are opened on the receiving box and correspond to the two absorption rings in a one-to-one correspondence. The absorption rings pass through the corresponding avoidance openings and abut against the inner walls of the avoidance openings. The release agent in the inner cavity of the receiving box is immersed in the absorption rings. Before the plywood is squeezed, the end of the plywood first pushes the force plate to rotate elastically, and the force plate drives the accommodating box to rotate toward the plywood, driving the two absorption rings to squeeze the plywood so that the absorption rings rotate to apply the release agent inside to both sides of the top surface of the plywood.

[0008] The above-mentioned sheet metal processing device, the linkage mechanism includes a first rotating shaft and a second rotating shaft rotatably mounted on the frame, a main gear is coaxially arranged on the first rotating shaft, and a slave gear meshing with the main gear is coaxially arranged on the second rotating shaft, the first rotating shaft drives the main gear to rotate synchronously, and the second rotating shaft drives the slave gear to rotate synchronously, the force plate is fixedly connected to the first rotating shaft, and the accommodating box is fixedly connected to the second rotating shaft.

[0009] In the above-mentioned sheet material processing device, the scraper includes a bottom plate and two side plates which are integrally provided. The end of the bottom plate is abutting surface and abuts and cooperates with the outer side surface of the corresponding steel strip.

[0010] In the above-mentioned sheet material processing device, a swing plate is fixedly mounted on the first rotating shaft, an arc-shaped compression spring is installed between the swing plate and the frame, a third rotating shaft is rotatably mounted on one end of the swing plate, and a brush is fixedly arranged on the third rotating shaft for extrusion-matching with the outer surface of the corresponding steel belt, and when the force plate is separated from the plywood, the elastic force of the arc-shaped compression spring drives the force plate to reset, and at the same time, the brush is extruded with the outer surface of the steel belt.

[0011] In the above-mentioned sheet material processing device, a plurality of pins intersecting with the brush are fixedly installed in the swing plate, a locking gear is coaxially arranged on the third rotating shaft, the third rotating shaft drives the locking gear to rotate synchronously, and a toothed plate engaged with the locking gear is fixedly installed on the frame. When the brush is squeezed against the outer surface of the steel belt, the toothed plate engages with the locking gear to lock the brush. When the plywood pushes the force plate to rotate, the toothed plate drives the locking gear to rotate so that the brush and the pins move relative to each other.

[0012] In the above-mentioned sheet metal processing device, an arc-shaped receiving groove is fixedly installed on the swing plate, and the arc-shaped receiving groove is located directly below the brush. When the brush and the pin move relative to each other, impurities cleaned from the brush fall into the arc-shaped receiving groove.

[0013] In the above-mentioned sheet material processing device, the plywood pushes the force plate to rotate, driving the locking gear to separate from the tooth plate. Based on inertia, the locking gear, the third rotating shaft and the brush continue to rotate after separation to make the stop position of the brush random, so that when the brush is squeezed against the outer surface of the steel strip again, the contact position between the brush and the outer surface of the steel strip is different.

[0014] In the above-mentioned sheet material processing device, a mounting seat is fixedly mounted on the swing plate, a nozzle is mounted on the mounting seat, and a hose connected to the nozzle is passed around from the side of the swing plate.

[0015] In the above-mentioned sheet material processing device, the plywood pushes the force plate to rotate, thereby driving the swing plate to rotate upward so that the swing plate drives the nozzle of the nozzle to rotate upward, thereby preventing the residual release agent in the nozzle from dripping from the nozzle of the nozzle.

[0016] A sheet metal processing process comprises the following steps: S1: Spraying release agent: The release agent is sprayed on the outer surface of the rotating steel belt through the spraying mechanism. At this time, the scraper contacts the outer surface of the steel belt so that the excess release agent is scraped off by the scraper. The scraped release agent flows along the scraper into the receiving box and is collected and gradually immersed in the two absorption rings. S2: Applying release agent to plywood: Apply force toward the steel belt to the plywood to be squeezed. Before the plywood enters between the two steel belts, the end of the plywood first pushes the force plate to rotate elastically, and the force plate drives the containing box to rotate toward the plywood, driving the two absorption rings to squeeze the plywood so that the absorption rings rotate and apply the release agent inside to both sides of the top surface of the plywood. Then the plywood enters between the two steel belts and is squeezed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the structural design of the scraping assembly, creates an interaction between the force plate and the plywood, and creates a linkage between the receiving box and the force plate, so that when the release agent is sprayed on the steel strip before the plywood is squeezed, the scraper fixedly installed on the receiving box can collect excess release agent into the receiving box, thereby avoiding the waste and pollution caused by the release agent dripping; and the force plate is cleverly used to drive the rotation design of the receiving box, so that in the process of pushing the plywood, the release agent collected in the inner cavity of the receiving box can be cleverly transferred to both sides of the top surface of the plywood by the absorption ring, so that the excess release agent is immediately reused, and is applied to both sides of the top surface of the plywood. Since both sides of the top surface of the plywood are covered with release agent, even if the amount of release agent on the outer surface of the steel strip is insufficient, the extended parts on both sides of the plywood are less likely to adhere to the surface of the steel strip when they contact the surface of the steel strip, thereby greatly reducing the probability of the extended parts on both sides of the plywood adhering to both sides of the surface of the steel strip with glue. It can be seen that the present invention can effectively solve the shortcomings of the prior art.

[0018] 2. The present invention fixes a swing plate on the first rotating shaft, fixes a tooth plate on the frame, and rotatably installs a third rotating shaft on the swing plate, a brush is installed on the third rotating shaft, and a locking gear engaged with the tooth plate is installed on the third rotating shaft. In the process of the plywood pushing the force application plate to rotate, not only can the release agent stored in the receiving box be applied to the plywood, but also the impurities adhered to the brush can be automatically cleaned, which has an unexpected technical effect; and the tooth plate can not only lock the brush when the brush is cleaning the surface of the steel strip, but also provide the brush with self-rotation power when the steel strip surface does not need to be cleaned, so that the brush can be automatically cleaned, and inertia can be used to make the position of the brush contacting the steel strip different each time to increase the service life of the brush, avoid the brush contacting the steel strip at the same position each time and increasing wear, and greatly increase the utilization rate of the tooth plate.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] First embodiment: See also Figures 1-8The present invention provides a sheet material processing device, comprising two steel belts 20 rotatably mounted on a frame 18, a scraping assembly 1 being mounted on the frame 18, the scraping assembly 1 comprising a force applying plate 2 elastically rotatably mounted on the frame 18, and a receiving box 7 rotatably mounted on the frame 18 and linked to the force applying plate 2 via a linkage mechanism; A scraper 8 is fixedly mounted on the receiving box 7 and is in communication with the inner cavity thereof and in contact with the outer surface of the corresponding steel strip 20 for scraping off excess release agent on the steel strip 20. The scraped release agent flows along the scraper 8 into the inner cavity of the receiving box 7 for storage. Two absorption rings 9 are rotatably mounted on the receiving box 7 and are squeezed and fitted in a one-to-one correspondence with the two sides of the top surface of the plywood 25. Two avoidance openings are opened on the receiving box 7 and correspond to the two absorption rings 9. The absorption rings 9 pass through the corresponding avoidance openings and abut against the inner walls of the avoidance openings. The release agent in the inner cavity of the receiving box 7 is immersed in the absorption rings 9. Before the plywood 25 is squeezed, the end of the plywood 25 first pushes the force plate 2 to rotate elastically, and the force plate 2 drives the accommodating box 7 to rotate toward the plywood 25, driving the two absorption rings 9 to squeeze the plywood 25 so that the absorption rings 9 rotate to apply the release agent inside to both sides of the top surface of the plywood 25.

[0024] The sheet metal processing device provided in this embodiment can prevent contamination of the steel strip and prevent the release agent from dripping and contaminating the working environment. The words related to direction and position involved in this embodiment are relative to the accompanying drawings. The "two sides" involved in this embodiment refer to the two sides along the width direction of the steel strip 20. Specifically, two sets of transmission rollers 19 are rotatably arranged on the frame 18. The two steel strips 20 are mounted on the two sets of transmission rollers 19 in a one-to-one correspondence. The plywood 25 passes between the two steel strips 20 to achieve the first extrusion. There are two transmission rollers 19 in each set of transmission rollers 19. The two transmission rollers 19 are connected by a transmission belt or a transmission chain. One of the transmission rollers 19 is connected to a drive motor for driving a set of transmission rollers 19 to rotate. The rotation of the transmission rollers 19 drives the corresponding steel strip 20 to rotate. The arrangement of the transmission rollers 19 and the arrangement of the steel strips 20 are both existing technologies and will not be repeated in this embodiment. Two sets of pressure rollers 21 are also rotatably provided on the frame 18 , and the two sets of pressure rollers 21 are in one-to-one contact with the inner side surfaces of the two steel belts 20 . The two sets of pressure rollers 21 are used to support the two steel belts 20 in one-to-one correspondence to improve the stability of the extruded plywood 25 . There is no limit to the number of pressure rollers 21 in each set of pressure rollers 21 and it can be determined according to the distance between the two transmission rollers 19 in each set of transmission rollers 19 . The frame 18 is also rotatably provided with a plurality of horizontally arranged feeding support rollers 22 and a plurality of horizontally arranged unloading support rollers 23. The rotation of the feeding support rollers 22 and the unloading support rollers 23 are equal, and the top height of the feeding support rollers 22 and the unloading support rollers 23 is the same as the top surface height of the steel belt 20 below. When the plywood 25 is extruded for the first time, the plywood 25 is placed on the feeding support roller 22, and then the plywood 25 is pushed toward between the two steel belts 20 so that the plywood 25 enters between the two steel belts 20 for extrusion. After the extrusion is completed, the plywood 25 passes through between the two steel belts 20 and falls on the unloading support roller 23.

[0025] This embodiment also includes a spraying mechanism (not shown in the figure) installed on the frame 18. Only the nozzle 17 is shown in the figure. The spraying mechanism is used to spray the release agent on the outer surface of the steel strip 20 or more specifically on both sides of the outer surface of the steel strip 20. The release agent is a liquid release agent. The spraying mechanism includes a box for containing the release agent, a hose connected to the box, a nozzle 17 connected to the end of the hose, and a pump body for conveying the release agent. The hose is made of plastic or rubber and is deformable. One end of the hose is connected to and communicated with the box, and the other end is connected to and communicated with the nozzle 17. The spraying mechanism is a prior art, and the specific detailed structure and connection method are not repeated here.

[0026] The focus of this embodiment is the structural design of the scraping assembly 1, which includes a force plate 2 elastically rotatably arranged on the frame 18 and a accommodating box 7 rotatably arranged on the frame 18 and linked with the force plate 2 through a linkage mechanism. When the force plate 2 rotates, the force plate 2 drives the accommodating box 7 to rotate through the linkage mechanism. The accommodating box 7 is located between the force plate 2 and the steel belt 20. The rotation direction of the force plate 2 is opposite to the rotation direction of the accommodating box 7. At the same time, the force plate 2 abuts against the plywood 25, so that the end of the plywood 25 can abut against the force plate 2 before being squeezed, and the force plate 2 is driven to rotate toward the steel belt 20 under the pushing force of the plywood 25. The force plate 2 drives the accommodating box 7 to rotate in a direction away from the steel belt 20 and close to the top of the plywood 25. When the bottom of the force plate 2 is located at the top of the plywood 25, the rotation angle of the force plate 2 reaches the maximum. The container 7 is provided with an inlet 701 communicating with its inner cavity. The scraper 8 extends through the inlet 701 so that one end of the scraper 8 is located within the inner cavity of the container 7 and the other end abuts and engages with the outer surface of the steel strip 20. The initial state is when the plywood 25 is not in contact with the force-applying plate 2. At this time, the elastic rotational force of the force-applying plate 2 drives the end of the scraper 8 to abut against the outer surface of the steel strip 20, so that the scraper 8 serves to limit the force-applying plate 2. The scraper 8 is also used to scrape off excess release agent from the steel strip 20. After the spraying mechanism sprays the release agent on the outer surface of the steel strip 20, the scraper 8 scrapes off the excess release agent from the steel strip 20 as the steel strip 20 rotates. The scraped release agent flows along the scraper 8 into the inner cavity of the container 7 for storage, allowing the container 7 to store the release agent. A fourth rotating shaft 901 is rotatably installed in the inner cavity of the storage box 7, and two absorption rings 9 are fixedly sleeved on the fourth rotating shaft 901. The absorption rings 9 are made of pure cotton, linen, collodion or fiber, as long as they have strong water absorption and elasticity. The absorption rings 9 are used to absorb the release agent into the inner cavity of the storage box 7 and cleverly apply the absorbed release agent to the plywood 25. Two avoidance openings corresponding to the two absorption rings 9 are opened on the storage box 7. The absorption rings 9 pass through the corresponding avoidance openings and abut against the inner walls of the avoidance openings so that the release agent in the inner cavity of the storage box 7 can contact the absorption rings 9 while the absorption rings 9 seal the avoidance openings to prevent the release agent in the inner cavity of the storage box 7 from leaking out.When the force plate 2 rotates to the maximum angle, as the plywood 25 continues to advance, the top surface of the plywood 25 squeezes the two absorption rings 9, causing the two absorption rings 9 to deform, so that the release agent immersed in the two absorption rings 9 is smeared one by one to both sides of the top surface of the plywood 25. Under the action of the squeezing force, the friction between the top surface of the plywood 25 and the absorption ring 9 is greater than the sum of the friction between the absorption ring 9 and the avoidance port and the rotational friction between the fourth rotating shaft 901 and the containing box 7, thereby driving the two absorption rings 9 to rotate in the process of continuous advancement of the plywood 25. The rotation of the absorption ring 9 causes the absorption ring 9 to continuously absorb the release agent in the inner cavity of the containing box 7 and continuously squeeze and smear it on both sides of the top surface of the plywood 25, so that the excess release agent scraped off by the scraper 8 can be immediately utilized, and then the plywood 25 enters between the two steel belts 20 and is squeezed. Since both sides of the plywood 25 are extended when being squeezed, applying a release agent to both sides of the plywood 25 in advance can effectively reduce the probability of the extended parts on both sides of the plywood 25 and the glue adhering to the steel strip 20 due to insufficient release agent on the steel strip 20.

[0027] Thus, it can be seen that the present invention, through the structural design of the scraping assembly 1, creates an interaction between the force plate 2 and the plywood 25, and creates a linkage between the receiving box 7 and the force plate 2, so that when the release agent is sprayed on the steel strip 20 before the plywood 25 is squeezed, the scraper 8 fixedly mounted on the receiving box 7 can collect the excess release agent into the receiving box 7, thereby avoiding the waste and pollution caused by the release agent dripping; and the force plate 2 is cleverly used to drive the rotation design of the receiving box 7 so that the release agent collected in the inner cavity of the receiving box 7 can be removed during the process of pushing the plywood 25. The absorption ring 9 is cleverly transferred to both sides of the top surface of the plywood 25, so that the excess release agent can be immediately reused, and is applied to both sides of the top surface of the plywood 25. Since both sides of the top surface of the plywood 25 are covered with the release agent, even if the amount of release agent on the outer surface of the steel strip 20 is insufficient, the extended portions on both sides of the plywood 25 are less likely to adhere to the surface of the steel strip 20 when they come into contact with the surface of the steel strip 20. This greatly reduces the probability that the extended portions on both sides of the plywood 25 will adhere to both sides of the surface of the steel strip 20 with glue. It can be seen that the present invention can effectively solve the shortcomings of the prior art.

[0028] The release agent in the inner cavity of the receiving box 7 can be injected in advance through the inlet 701 to avoid insufficient release agent applied to the surface of the plywood 25 .

[0029] In this embodiment, the linkage mechanism includes a first rotating shaft 3 and a second rotating shaft 6 rotatably mounted on a frame 18. A main gear 4 is coaxially provided on the first rotating shaft 3, and the main gear 4 is key-connected or fixedly connected to the first rotating shaft 3. A slave gear 5 is coaxially provided on the second rotating shaft 6 and meshes with the main gear 4. The second rotating shaft 6 is key-connected or fixedly connected to the slave gear 5. The first rotating shaft 3 drives the main gear 4 to rotate synchronously, and the second rotating shaft 6 drives the slave gear 5 to rotate synchronously. The force application plate 2 is fixedly connected to the first rotating shaft 3, and the receiving box 7 is fixedly connected to the second rotating shaft 6. Specifically, the main gear 4 and the slave gear 5 both rotate on their own. When an external force acts on the force application plate 2, the force application plate 2 drives the main gear 4 to rotate via the first rotating shaft 3. The main gear 4 drives the slave gear 5 to rotate through meshing, and the slave gear 5 then drives the receiving box 7 to rotate. Due to the meshing of the main gear 4 and the slave gear 5, the force application plate 2 and the receiving box 7 rotate in opposite directions.

[0030] The scraper 8 includes an integral bottom plate and two side plates, the end of the bottom plate being abutting surfaces 801 that abut against the outer side surface of the corresponding steel strip 20. The abutting surfaces 801 have a longer extension toward the steel strip 20 relative to the two side plates of the scraper 8 so that when the abutting surfaces 801 abut against the outer surface of the steel strip 20, the side plates of the scraper 8 do not abut against the steel strip 20. The two side plates of the scraper 8 are used to block the release agent and prevent the release agent from flowing out from both sides of the scraper 8. In the initial state, the abutting surface 801 abuts against the outer surface of the steel strip 20. At this time, the bottom plate of the scraper 8 is tilted downward from the steel strip 20 toward the receiving box 7 so that the release agent scraped off by the scraper 8 can flow into the inner cavity of the receiving box 7 along the bottom plate of the scraper 8.

[0031] Furthermore, a swing plate 10 is fixedly mounted on the first rotating shaft 3, and an arc-shaped compression spring 26 is installed between the swing plate 10 and the frame 18. The elastic rotation of the force plate 2 is achieved based on the elastic force of the arc-shaped compression spring 26. A third rotating shaft 11 is rotatably mounted on one end of the swing plate 10, and a brush 12 is fixedly arranged on the third rotating shaft 11 for extrusion-matching with the outer surface of the corresponding steel belt 20. When the force plate 2 is separated from the plywood 25, the elastic force of the arc-shaped compression spring 26 drives the force plate 2 to reset, and at the same time, the brush 12 is extruded with the outer surface of the steel belt 20. Specifically, the number of brushes 12 is two or one. When there are two brushes 12, they correspond one to one with the two sides of the outer surface of the steel strip 20. When there is one brush 12, the axial length of the brush 12 is increased so that one brush 12 can cover the entire width of the steel strip 20. Since the steel strip 20 is squeezed through the plywood 25, solid-liquid mixed impurities are easily adhered to both sides of its outer surface. After completing one extrusion of the plywood 25, the position on the outer surface of the steel strip 20 that originally contacted the extended parts on both sides of the plywood 25 gradually contacts and squeezes the brush 12. During the rotation of the steel strip 20, relative movement is generated between the brush 12, so that the brush 12 cleans the impurities adhered to the outer surface of the steel strip 20, so that the surface of the steel strip 20 is cleaner when it squeezes the plywood 25 next time.

[0032] Among them, a cavity is formed inside the swing plate 10, and the cavity passes through the end face of the swing plate 10 close to the brush 12. A number of pins 15 that intersect with the brush 12 are fixedly installed in the swing plate 10. A locking gear 14 is coaxially arranged on the third rotating shaft 11. The third rotating shaft 11 is key-connected or fixedly connected to the locking gear 14. The third rotating shaft 11 drives the locking gear 14 to rotate synchronously. A tooth plate 13 that meshes with the locking gear 14 is fixedly installed on the frame 18. When the brush 12 is squeezed against the outer surface of the steel belt 20, the tooth plate 13 meshes with the locking gear 14 to lock the brush 12. When the plywood 25 pushes the force plate 2 to rotate, the tooth plate 13 drives the locking gear 14 to rotate so that the brush 12 and the pins 15 move relative to each other. Specifically, based on the meshing cooperation between the tooth plate 13 and the locking gear 14, when the brush 12 abuts the outer surface of the steel belt 20, the tooth plate 13 and the locking gear 14 are meshed to prevent the locking gear 14 from rotating, and thus the brush 12 cannot rotate, so that the tooth plate 13 locks the brush 12, and when the steel belt 20 rotates, relative movement is generated between the steel belt 20 and the brush 12, so that the brush 12 cleans the outer surface of the steel belt 20. At the same time, due to the meshing of the toothed plate 13 and the locking gear 14, when the force plate 2 is pushed and rotated by the plywood 25, the force plate 2 drives the swing plate 10 to rotate synchronously about the first rotation axis 3. The swing plate 10 compresses the arc-shaped compression spring 26 and deforms. The swing plate 10 drives the locking gear 14 to rotate along with the swing plate 10 about the first rotation axis 3 while rotating about the third rotation axis 11. The rotation of the third rotation axis 11 drives the brush 12 to rotate, thereby generating relative motion between the brush 12 and the pin 15, causing the brush 12 to collide with the pin 15, thereby removing impurities adhered to the brush 12 and cleaning the brush 12. When the force plate 2 and the plywood 25 are offset, the elastic force of the arc-shaped compression spring 26 is released, causing the force plate 2, the swing plate 10, and the receiving box 7 to return to their initial state. At this time, the abutment surface 801 abuts the outer surface of the steel belt 20, and the brush 12 also abuts the outer surface of the steel belt 20.

[0033] The swing plate 10 is fixedly mounted with an arc-shaped receiving groove 1001, located directly below the brush 12. When the brush 12 and the pins 15 move relative to each other, impurities removed from the brush 12 fall into the arc-shaped receiving groove 1001 and are collected. The cavity of the swing plate 10 is connected to the arc-shaped receiving groove 1001. When the swing plate 10 is driven upward by the force plate 2, impurities in the arc-shaped receiving groove 1001 are gradually transferred into the inner cavity of the swing plate 10. An openable cleaning port (not shown) is installed on the swing plate 10, which allows cleaning of the inner cavity of the swing plate 10.

[0034] In this embodiment, the plywood 25 pushes the force plate 2 to rotate, driving the locking gear 14 to separate from the tooth plate 13. Based on inertia, the locking gear 14, the third rotating shaft 11 and the brush 12 continue to rotate after separation, so that the stop position of the brush 12 is random. Therefore, when the brush 12 is squeezed against the outer surface of the steel belt 20 again, the contact position of the brush 12 with the outer surface of the steel belt 20 is different, thereby avoiding the brush 12 from contacting the steel belt 20 at the same position each time and increasing wear, thereby increasing the service life of the brush 12.

[0035] Thus, the present invention fixes the swing plate 10 on the first rotating shaft 3, fixes the tooth plate 13 on the frame 18, and rotatably installs the third rotating shaft 11 on the swing plate 10, installs the brush 12 on the third rotating shaft 11, and installs the locking gear 14 engaged with the tooth plate 13 on the third rotating shaft 11, so that when the plywood 25 pushes the force plate 2 to rotate, not only can the release agent stored in the receiving box 7 be applied to the plywood 25, but also the impurities adhering to the brush 12 can be automatically cleaned. The tooth plate 13 can not only lock the brush 12 when the brush 12 is cleaning the surface of the steel strip 20, but also provide the brush 12 with the power of self-rotation when the surface of the steel strip 20 does not need to be cleaned, so that the brush 12 can automatically clean. Inertia can also be used to make the position of the brush 12 in contact with the steel strip 20 different each time to increase the service life of the brush 12, and avoid the brush 12 contacting the steel strip 20 at the same position each time to increase wear, so that the utilization rate of the tooth plate 13 is greatly increased.

[0036] In this embodiment, a mounting base 16 is fixedly mounted on the swing plate 10. A spray head 17 is mounted on the mounting base 16. A hose (not shown) connected to the spray head 17 passes around the side of the swing plate 10 and is used to circulate the release agent. There are at least two spray heads 17, which spray the release agent onto both sides of the outer surface of the steel strip 20, one for each side.

[0037] When the plywood 25 pushes the force applying plate 2 to rotate, the swing plate 10 is driven to rotate upwards, so that the swing plate 10 drives the nozzle of the spray head 17 to rotate upwards, thereby preventing the mold release agent remaining in the spray head 17 from dripping from the nozzle of the spray head 17.

[0038] In this embodiment, the nozzle 17 is located between the brush 12 and the scraper 8, and the scraper 8 is located at the bottom. When the plywood 25 is squeezed, the mold release agent is first sprayed on the outer surface of the steel belt 20 through the nozzle 17, and then the plywood 25 is pushed to move. Before the plywood 25 contacts the force plate 2, the nozzle 17 stops spraying the mold release agent. After that, the plywood 25 abuts against the force plate 2 and pushes the force plate 2 to rotate elastically. The force plate 2 drives the swing plate 10 to rotate upward, and the swing plate 10 drives the nozzle 17 to rotate upward through the mounting seat 16, so that the mold release agent remaining in the nozzle 17 will not drip from the nozzle of the nozzle 17.

[0039] Among them, please refer to the attached Figure 1 As shown, there are two sets of scraping assemblies 1, one corresponding to each of the two steel belts 20. A plurality of secondary extrusion rollers 24 are rotatably mounted on the frame 18 in an array. The secondary extrusion rollers 24 are positioned below the lower steel belt 20. The distance between the top of the secondary extrusion rollers 24 and the bottom of the lower steel belt 20 is equal to the distance between the two steel belts 20, allowing the plywood 25 to be secondary extruded between the steel belt 20 and the secondary extrusion rollers 24. The first and second extrusion operations of the plywood 25 are identical and will not be further described. There are two spraying mechanisms, one corresponding to each of the two steel belts 20. The two spraying mechanisms spray release agent on the outer surfaces of the two steel belts 20, and the two scraping assemblies 1 scrape off excess release agent from the two steel belts 20. The first and second extrusions of the plywood 25 can be performed simultaneously, thereby improving work efficiency.

[0040] In this embodiment, there are two master gears 4 and two slave gears 5, each meshing in a one-to-one correspondence. There are also two toothed plates 13 and two locking gears 14, each meshing in a one-to-one correspondence, thereby improving force balance. The rear toothed plate 13 is directly and fixedly connected to the frame 18. This embodiment also includes a fixed support plate (not shown). The front toothed plate 13 is fixedly connected to the support plate. The first rotating shaft 3, the second rotating shaft 6, the drive roller 19, the pressure roller 21, the loading support roller 22, the unloading support roller 23, and the secondary extrusion roller 24, the end away from the frame 18, are all rotatably connected to the support plate.

[0041] The bottom surface of the inner cavity of the accommodating box 7 is tilted downward toward the two absorption rings 9 , so that the release agent in the inner cavity of the accommodating box 7 flows toward the two absorption rings 9 .

[0042] Second embodiment: The structure involved in this embodiment is based on the structure in the first embodiment. This embodiment provides a sheet metal processing process, which includes the following steps: S1: Spraying release agent: The release agent is sprayed on the outer surface of the rotating steel belt 20 by the spraying mechanism. At this time, the scraper 8 abuts against the outer surface of the steel belt 20, so that the excess release agent is scraped off by the scraper 8. The scraped release agent flows along the scraper 8 into the receiving box 7 and is collected and gradually immersed in the two absorption rings 9; S2: Applying mold release agent to the plywood: Apply force toward the steel belts 20 to the plywood 25 to be squeezed. Before the plywood 25 enters between the two steel belts 20, the end of the plywood 25 first pushes the force-applying plate 2 to elastically rotate. The force-applying plate 2 then drives the receiving box 7 to rotate toward the plywood 25, driving the two absorption rings 9 to squeeze the plywood 25 so that the absorption rings 9 rotate and apply the mold release agent inside to both sides of the top surface of the plywood 25. Then, the plywood 25 enters between the two steel belts 20 and is squeezed. S3: Secondary extrusion: After the steel strip is squeezed between the two steel strips 20, it is subjected to secondary extrusion. Before the secondary extrusion, another spraying mechanism first sprays a release agent on the outer surface of the lower steel strip 20. After that, the action between another set of scraping components and the lower steel strip 20 is the same as steps S1 and S2, which will not be repeated.

[0043] In step S1, a swing plate 10 is fixedly mounted on the first rotating shaft 3, and an arc-shaped compression spring 26 is installed between the swing plate 10 and the frame 18. The elastic rotation of the force plate 2 is realized based on the elastic force of the arc-shaped compression spring 26. A third rotating shaft 11 is rotatably mounted on one end of the swing plate 10, and a brush 12 is fixedly arranged on the third rotating shaft 11 for extrusion-matching with the outer surface of the corresponding steel belt 20. When the force plate 2 is separated from the plywood 25, the elastic force of the arc-shaped compression spring 26 drives the force plate 2 to reset, and at the same time, the brush 12 is extruded with the outer surface of the steel belt 20. Specifically, the number of brushes 12 is two or one. When there are two brushes 12, they correspond one to one with the two sides of the outer surface of the steel strip 20. When there is one brush 12, the axial length of the brush 12 is increased so that one brush 12 can cover the entire width of the steel strip 20. Since the steel strip 20 is squeezed through the plywood 25, solid-liquid mixed impurities are easily adhered to both sides of its outer surface. After completing one extrusion of the plywood 25, the position on the outer surface of the steel strip 20 that originally contacted the extended parts on both sides of the plywood 25 gradually contacts and squeezes the brush 12. During the rotation of the steel strip 20, relative movement is generated between the brush 12, so that the brush 12 cleans the impurities adhered to the outer surface of the steel strip 20, so that the surface of the steel strip 20 is cleaner when it squeezes the plywood 25 next time.

[0044] In step S2, a cavity is formed inside the swing plate 10, and the cavity passes through the end surface of the swing plate 10 close to the brush 12. A number of pins 15 intersecting with the brush 12 are fixedly installed in the swing plate 10, and a locking gear 14 is coaxially arranged on the third rotating shaft 11. The third rotating shaft 11 is key-connected or fixedly connected to the locking gear 14, and the third rotating shaft 11 drives the locking gear 14 to rotate synchronously. A tooth plate 13 engaged with the locking gear 14 is fixedly installed on the frame 18. When the brush 12 is squeezed against the outer surface of the steel belt 20, the tooth plate 13 engages with the locking gear 14 to lock the brush 12. When the plywood 25 pushes the force plate 2 to rotate, the tooth plate 13 drives the locking gear 14 to rotate so that the brush 12 and the pins 15 move relative to each other. Specifically, based on the meshing cooperation between the tooth plate 13 and the locking gear 14, when the brush 12 abuts the outer surface of the steel belt 20, the tooth plate 13 and the locking gear 14 are meshed to prevent the locking gear 14 from rotating, and thus the brush 12 cannot rotate, so that the tooth plate 13 locks the brush 12, and when the steel belt 20 rotates, relative movement is generated between the steel belt 20 and the brush 12, so that the brush 12 cleans the outer surface of the steel belt 20. At the same time, due to the meshing of the toothed plate 13 and the locking gear 14, when the force plate 2 is pushed and rotated by the plywood 25, the force plate 2 drives the swing plate 10 to rotate synchronously about the first rotation axis 3. The swing plate 10 compresses the arc-shaped compression spring 26 and deforms. The swing plate 10 drives the locking gear 14 to rotate along with the swing plate 10 about the first rotation axis 3 while rotating about the third rotation axis 11. The rotation of the third rotation axis 11 drives the brush 12 to rotate, thereby generating relative motion between the brush 12 and the pin 15, causing the brush 12 to collide with the pin 15, thereby removing impurities adhered to the brush 12 and cleaning the brush 12. When the force plate 2 and the plywood 25 are offset, the elastic force of the arc-shaped compression spring 26 is released, causing the force plate 2, the swing plate 10, and the receiving box 7 to return to their initial state. At this time, the abutment surface 801 abuts the outer surface of the steel belt 20, and the brush 12 also abuts the outer surface of the steel belt 20.

[0045] The swing plate 10 is fixedly mounted with an arc-shaped receiving groove 1001, located directly below the brush 12. When the brush 12 and the pins 15 move relative to each other, impurities removed from the brush 12 fall into the arc-shaped receiving groove 1001 and are collected. The cavity of the swing plate 10 is connected to the arc-shaped receiving groove 1001. When the swing plate 10 is driven upward by the force plate 2, impurities in the arc-shaped receiving groove 1001 are gradually transferred into the inner cavity of the swing plate 10. An openable cleaning port (not shown) is installed on the swing plate 10, which allows cleaning of the inner cavity of the swing plate 10.

[0046] In this embodiment, the plywood 25 pushes the force plate 2 to rotate, driving the locking gear 14 to separate from the tooth plate 13. Based on inertia, the locking gear 14, the third rotating shaft 11 and the brush 12 continue to rotate after separation, so that the stop position of the brush 12 is random. Therefore, when the brush 12 is squeezed against the outer surface of the steel belt 20 again, the contact position of the brush 12 with the outer surface of the steel belt 20 is different, thereby avoiding the brush 12 from contacting the steel belt 20 at the same position each time and increasing wear, thereby increasing the service life of the brush 12.
