Description

Technical Field

[0001] This invention is applied to the background of sandpaper production, and is named a bonding device for sandpaper production. Background Technology

[0002] Sandpaper is an essential grinding tool in the machining industry, and its demand and usage have shown a year-on-year growth trend with the development of the machining, construction, and industrial technology sectors. The raw materials for producing sandpaper are abrasive grains and adhesive cloth. The production process can be divided into several steps: unwinding the raw cloth, applying adhesive, applying abrasive particles, re-adhesive coating, drying and curing, and finally, the finished product. In this assembly line production process, abrasive application is crucial; simply put, it involves evenly coating the surface of the raw paper with abrasive material. Therefore, the quality of sandpaper depends to a certain extent on the uniformity of the abrasive grains on its surface.

[0003] However, during the production process, many problems arise when sandpaper is bonded to the base paper due to improper operation or other reasons. For example, the base paper may shift due to different bonding angles, air bubbles may exist in the inner layer after bonding, and wrinkles in the sandpaper or base paper may result in low product quality after bonding. Existing sandpaper bonding processes mostly use rollers to bond the sandpaper to the base paper with solidifying adhesive. Although this can avoid some problems, it cannot guarantee product quality. In today's world, where economic efficiency and automation requirements are increasingly high, low-quality sandpaper products will not be favored by businesses, resulting in waste of products and money. At the same time, substandard sandpaper will also cause certain adverse consequences in later use. Therefore, rudimentary bonding machines will no longer be practical.

[0004] Therefore, it is necessary to provide an adhesive device for sandpaper production that can achieve a good adhesive effect. Summary of the Invention

[0009] In one embodiment, a pneumatic rod is fixedly installed above the slide rail, a cylinder is provided above the pneumatic rod, a main support plate is fixedly installed above the cylinder, and a support foot is fixedly installed on the outer side of the main support plate.

[0010] In one embodiment, a fixing block is fixedly installed on the rear side of the base, a rotating handle is provided on the front side of the fixing block, a support column is provided below the rotating handle, a fixing pressure plate is fixedly installed below the support column, a sliding groove is provided on the top of the base, a sliding block is slidably connected inside the sliding groove, and a clamping plate is provided on the top of the sliding block.

[0011] In one embodiment, the base has an outer plate on its front side, a winding drum is connected to the inner bearing of the outer plate, a first conveying drum is connected to the inner bearing of the outer plate, a second conveying drum is connected to the inner bearing of the outer plate, and a limit plate is provided on the inner side of the outer plate.

[0012] In one embodiment, a rotating machine is provided below the second support plate, and a cutting blade is provided on the outside of the rotating machine.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] 1. A small motor is installed inside the power compartment, which drives the power gear to rotate. The first gear, meshing with the power gear, will also rotate. The first gear, in the same direction, drives the second gear fixedly connected to it. Simultaneously, the second gear drives the second support shaft to rotate via a belt. The second support shaft then drives the roller brush to rotate, thus achieving the effect of applying adhesive to the backing paper. Compared to manual brushing or direct spraying of adhesive, this method achieves a uniform application of adhesive to the backing paper, ensuring every area is covered and improving adhesion. The rotation of the second gear also drives the first support shaft to rotate. The first support shaft, through a fixedly connected first bevel gear, drives the second bevel gear to rotate as well. The second bevel gear then drives the rotating disk. The rotating disc, with its strip-shaped interior, can further spread the adhesive applied to the base paper by the roller brush, improving adhesion and preventing uneven adhesion that could lead to uneven bonding of the base paper and displacement of the original sandpaper during later use. Simultaneously, a scraper and collection groove are located on the rear side of the first support plate to remove and collect any adhesive carried to the sides of the base by the rotating disc, allowing for recycling and preventing overflow from the sides of the base, thus reducing cleaning time. The roller brush and rotating disc are fixed to the first support frame and slide slowly and evenly forward on the slide rail via a fixed connection to the first slider, thus applying and spreading the adhesive evenly across the entire base paper on the base. This convenient and quick process reduces production time and improves production quality.

[0015] 2. The rotating block is equipped with a rotating mechanism that can drive the third support shaft to rotate through the operator's operation. After adding sufficient solidifying adhesive to the storage tank, the operator controls the rotating block to rotate the support arm and align the residence chamber with the roller brush. The operator also controls the control chamber, which has the same rotating mechanism, to change the angle between the residence chamber and the roller brush, allowing the solidifying adhesive to be better squeezed onto the roller brush. Subsequently, after the first slider is activated, the operator controls the pressure chamber to suck the solidifying adhesive from the storage tank into the delivery pipe and accumulate it in the residence chamber. Continued pressure is applied to squeeze the solidifying adhesive in the residence chamber out from multiple nozzles. This prevents the accidental accumulation of large pieces of solidifying adhesive on the roller brush due to squeezing out all the solidifying adhesive at once, and also allows the scraper to spread the solidifying adhesive more evenly. The operator can control the flow rate of the nozzles by controlling the pressure chamber, thus adapting the amount of solidifying adhesive to various situations.

[0016] 3. When the first slider moves forward on the slide rail, the second slider starts simultaneously, driving the second support frame forward on the slide rail. The original sandpaper will be rolled up on the pressure barrel connected by the support rod. The pressure barrel itself has a certain weight and can fall onto the bottom paper of the base. Before the overall device is started, the worker needs to fix one end of the sandpaper on the pressure barrel. Then, as the roller rotates and moves forward, it lays the sandpaper flat on the bottom paper. At the same time, the spring rod will apply pressure to the pressure barrel again, so that the sandpaper can be tightly attached to the bottom paper. At the same time, the air in the solidified glue is squeezed out, and the excess solidified glue between the bottom paper and the original sandpaper is squeezed out. This achieves the effect of tightly attaching the sandpaper to the bottom paper, expelling excess air and solidified glue, improving the adhesion, resulting in fast production efficiency and uniform engineering without unexpected situations.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application.

In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] Please see Figure 1-11The present invention provides a technical solution: an adhesive device for sandpaper production, comprising a base 1 and a slide rail 2. A first slider 4 is slidably connected to the front side of the slide rail 2. A first support frame 5 is fixedly installed inside the first slider 4. A first support plate 6 is fixedly installed to the rear side of the first support frame 5. A power chamber 7 is disposed inside the first support plate 6. A power gear 8 is disposed inside the power chamber 7. A first support shaft 10 is connected to the front bearing of the power chamber 7. A first gear 9 is fixedly installed above the first support shaft 10 and meshes with the power gear 8. A first bevel gear 13 is fixedly installed at the outer end of the first support shaft 10. A second bevel gear 14 meshes below the first bevel gear 13 and is connected to the power chamber 7 by a bearing. A rotating disk 15 is disposed below the second bevel gear 14. A rotating disk 15 is fixedly installed to the right side of the first gear 9. A second gear 11 is provided, with a belt 12 meshing on its outer side. A second support shaft 16 is connected to the inner bearing of the first support frame 5. A roller brush 17 is provided on the inner side of the second support shaft 16. The belt 12 meshes with the second support shaft 16. A scraper 18 is provided at the front of the first support frame 5. A curing adhesive is applied to the roller brush 17. When the roller brush 17 rotates, the scraper 18, which has a certain gap with the roller brush 17, will spread the curing adhesive evenly for the first time, thereby ensuring the subsequent bonding effect. A base paper will be placed on the base 1. In order to adhere the original sandpaper to the base paper, a small motor is provided inside the power chamber 7, which can drive the power gear 8 to rotate. At this time, the first gear 9, which meshes with the power gear 8, will also be driven to rotate. The first gear 9 drives the second gear 11, which is fixedly connected to it, in the same direction.Simultaneously, the second gear 11 drives the second support shaft 16 to rotate via the belt 12. The second support shaft 16 then drives the roller brush 17 to rotate, thereby achieving the effect of roller brushing the adhesive onto the backing paper. Compared to the previous manual brushing or direct spraying of adhesive, this method achieves the effect of evenly applying adhesive to the backing paper, ensuring that every part of the backing paper is covered with adhesive, thus improving the adhesion. When the second gear 11 rotates, it also drives the first support shaft 10 to rotate. The first support shaft 10 drives the second bevel gear 14 to rotate together via the fixedly connected first bevel gear 13. The second bevel gear 14 then drives the rotating disk 15 to rotate. The interior of the rotating disk 15 is strip-shaped, which can distribute the adhesive applied to the backing paper by the roller brush 17. The adhesive is applied a second time to improve adhesion and prevent uneven curing, which could lead to uneven bonding of the base paper and displacement of the original sandpaper during later use. Simultaneously, a scraper and collection groove are provided on the rear side of the first support plate 6 to remove and collect the cured adhesive carried to both sides of the base 1 by the rotating disk 15, allowing for recycling and preventing overflow from the sides of the base 1, thus reducing cleaning time. The roller brush 17 is fixed to the first support frame 5 along with the rotating disk 15 and slides slowly and uniformly forward on the slide rail 2 via the fixed connection of the first slider 4. This allows for the application and even spreading of the cured adhesive across the entire base paper on the base 1, making the process convenient, quick, reducing production time, and improving production quality.

[0033] A second support plate 19 is provided on the front side of the first support frame 5. A rotating block 20 is fixedly installed above the second support plate 19. A third support shaft 21 is provided on the inner side of the rotating block 20. A support arm 22 is provided on the outer side of the third support shaft 21. A control chamber 23 is connected to the inner bearing of the support arm 22. A storage tank 24 is provided on the rear side of the control chamber 23. A pressure chamber 29 is provided on the inner side of the control chamber 23. A conveying pipe 25 is provided on the inner side of the storage tank 24. An extension pipe 26 is provided on the front side of the control chamber 23. A residence chamber 27 is provided on the front side of the extension pipe 26. The conveying pipe 25 and the residence chamber 27 are interconnected. The pressure chamber 29 and the storage tank 24 are interconnected. A spray head 28 is provided on the front side of the residence chamber 27. A rotating mechanism is provided inside the rotating block 20, which can drive the third support shaft 21 to rotate through the operation of the worker. The worker can then control the storage... After adding sufficient gelling glue to tank 24, control the rotating block 20 to rotate the support arm 22 and align the residence chamber 27 with the roller brush 17. Control the control chamber 23, which has the same rotating mechanism, to change the angle between the residence chamber 27 and the roller brush 17, so that the gelling glue can be better squeezed onto the roller brush 17. Then, after the first slider 4 is started, the worker controls the pressure chamber 29 to suck the gelling glue in the storage tank 24 into the delivery pipe 25 and accumulate it in the residence chamber 27. Continue to apply pressure to squeeze the gelling glue in the residence chamber 27 out of multiple spray nozzles 28. This can prevent the accidental situation of large pieces of gelling glue accumulating on the roller brush 17 due to squeezing out all the gelling glue at once. At the same time, it can also make the scraper 18 spread the gelling glue more evenly. The worker can control the flow rate of the spray nozzles 28 by controlling the pressure chamber 29, so that the amount of gelling glue can be adapted to various situations.

[0034] A second slider 3 is slidably connected to the rear side of the slide rail 2. A second support frame 54 is provided above the second slider 3. A fourth support shaft 30 is provided inside the second support frame 54. The middle bearing of the fourth support shaft 30 is connected to the first connecting plate 31. The front bearing of the first connecting plate 31 is connected to the second connecting plate 32. The lower bearing of the second connecting plate 32 is connected to the motor 33. The inner bearing of the second support frame 54 is connected to the top plate 35. A spring rod 36 is provided below the top plate 35. The inner bearing of the spring rod 36 is connected to the pressure tank 34. The inner bearing of the second slider 3 is connected to the support rod 37. The support rod 37 is connected to the pressure tank 34 by a bearing. The power shaft of the motor 33 is connected to the pressure tank 34. When the first slider 4 is transported forward on the slide rail 2, the second slider 3... The two sliders 3 start together, driving the second support frame 54 forward on the slide rail 2. The original sandpaper will be rolled up on the pressure barrel 34 connected by the support rod 37. The pressure barrel 34 itself has a certain weight and can fall on the bottom paper of the base 1. Before the overall device starts, the worker needs to fix one end of the sandpaper on the pressure barrel 34. Then, while the roller rotates and moves forward, it lays the sandpaper flat on the bottom paper. At the same time, the spring rod 36 will apply pressure to the pressure barrel 34 again, so that the sandpaper can be tightly attached to the bottom paper. At the same time, the air in the curing glue is squeezed out, and the excess curing glue between the bottom paper and the original sandpaper is squeezed out. This can achieve the effect of tightly attaching the sandpaper to the bottom paper, expelling excess air and curing glue, improving the adhesion, and making the production efficiency fast and the process uniform without any unexpected situations.

[0035] An air spring 41 is fixedly installed above the slide rail 2. An air cylinder 40 is installed above the air spring 41. A main support plate 39 is fixedly installed above the air cylinder 40. Support feet 38 are fixedly installed on the outside of the main support plate 39. Before laying the base paper on the base 1, the air cylinder 40 will retract the internal air spring 41 and lift the entire slide rail 2 to facilitate the worker to lay the base paper. At the same time, different sandpaper sizes can also be adjusted by the air cylinder 40 to change the gap between the overall device and the base paper, or the air spring 41 can be extended further by the air cylinder 40 to increase the pressure of the sandpaper on the base paper and improve the adhesion.

[0036] A fixing block 42 is fixedly installed on the rear side of the base 1. A rotating handle 43 is provided on the front side of the fixing block 42. A support column 44 is provided below the rotating handle 43. A fixing pressure plate 45 is fixedly installed below the support column 44. A sliding groove 51 is provided on the top of the base 1. A sliding block 52 is slidably connected inside the sliding groove 51. A clamping plate 53 is provided above the sliding block 52. The clamping plate 53 will hold the end of the base paper. Then, the sliding block 52 slides backward in the sliding groove 51 to drive the base paper to be laid on the base 1, thereby increasing the laying speed. After the base paper is laid, the worker needs to fix one end of the base paper to the sandpaper to complete the subsequent bonding work. Therefore, the worker will... The top of the base paper and the top of the sandpaper are placed at the end of the base 1. Then, the rotating handle 43 and the support column 44 are rotated so that the fixing plate 45 presses on the base paper and sandpaper. Then, the pins are inserted to make the fixing plate 45 immovable, thereby fixing the base paper and sandpaper. Because the fixing plate 45 can fit with the base 1 after the two pins are inserted into the rotating handle 43, the sandpaper and base paper are fixed in position between the base 1 and the fixing plate 45 after the pins are inserted. At the same time, multiple protruding nails are provided below the fixing plate 45 to increase the pressure while fixing the position, prevent accidental displacement during the bonding process, and improve the bonding effect.

[0037] An outer plate 46 is provided on the front side of the base 1. A winding drum 47 is connected to the inner bearing of the outer plate 46. A first conveying drum 48 is connected to the inner bearing of the outer plate 46. A second conveying drum 49 is connected to the inner bearing of the outer plate 46. A limiting plate 50 is provided on the inner side of the outer plate 46. The bottom paper is wound on the winding drum 47. The bottom paper passes through the first conveying drum 48 and the second conveying drum 49 and passes under the limiting plate 50 before being laid flat on the base 1. This can reduce excessive rotation of the winding drum 47 when laying the bottom paper, prevent the bottom paper from shifting, and prevent gaps between the bottom paper and the base 1. After the bottom paper is laid and the top is fixed, the winding drum 47 will rotate in the opposite direction to tighten the bottom paper a second time, thereby ensuring that the bottom paper is tightly attached to the base 1, improving the bonding effect, and preventing shifting during the bonding process.

[0038] A rotating machine 55 is provided below the second support plate 19, and a cutting blade 56 is provided on the outside of the rotating machine 55. After the bonding is completed, the rotating machine 55 lowers the cutting blade 56 and pushes it from right to left in the track groove inside the second support plate 19 to cut the bonded sandpaper, which is convenient and quick.
