Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a surface grinding and polishing device for bathroom towel racks and its usage method. Background Technology

[0002] The bathroom towel racks currently on the market come in a variety of novel styles, with beautiful appearances and surfaces mainly treated with electroplating and spraying. Besides round, square, flat, and waist-shaped tubes, there are also various other irregular shapes. For electroplated bathroom towel racks, a polishing process involving coarse sanding, fine sanding, and then fine sanding, followed by cleaning with sisal and cloth wheels, is typically performed before electroplating.

[0003] However, the following problems still exist during the polishing and sanding process of the towel rack surface:

[0004] 1. Most bathroom towel racks have many corners and nooks, which polishing machines cannot work on. They are usually polished manually in small areas by small grinding wheels and small polishing machines, which can easily cause polishing deformation, high surface roughness of the sanding belt texture, and high cost.

[0005] 2. Polishing and sanding bathroom towel racks is mostly done manually, resulting in low efficiency and affecting the mass production of bathroom towel racks.

[0006] 3. The debris generated during polishing and grinding not only affects the environment but also poses health hazards to workers. In addition, the debris cannot be collected, resulting in a waste of resources.

[0007] To address the aforementioned issues, this invention proposes a surface grinding and polishing device for bathroom towel racks and its usage method. Summary of the Invention

[0008] This invention provides a surface grinding and polishing device for bathroom towel racks and its usage method, which solves the shortcomings of existing technologies such as poor quality, low polishing efficiency, and waste of resources caused by manual polishing which results in debris flying everywhere and cannot be collected.

[0009] This invention provides the following technical solution:

[0010] A bathroom towel rack surface grinding and polishing device includes: a base and a bathroom towel rack, wherein a box for polishing the bathroom towel rack is provided above the base, and the box and the base are elastically connected by multiple large springs;

[0011] The top of the box is provided with a platform for sealing the box, and centrifugal vibration motors are fixedly connected to both ends of the box.

[0012] The clamping structure, located at the bottom of the platform, is used to clamp the bathroom towel rack, which can then be used to polish multiple bathroom towel racks later.

[0013] A collection structure, located inside the chamber, is used to collect the debris generated during the polishing process;

[0014] The grinding stone discharge structure, located inside the chamber, is used to discharge the grinding stones inside the chamber, making it easier to recycle the debris later.

[0015] In one possible design, the clamping structure includes fixed clamping molds fixedly connected to both sides of the bottom of the platform. Two movable clamping molds are slidably connected to the bottom of the platform, and adjacent movable and fixed clamping molds are used to clamp the bathroom towel rack. Each movable and fixed clamping mold contains multiple sealing plugs. Both ends of the bathroom towel rack have threaded holes that mate with the sealing plugs. The mating of the sealing plugs with the threaded holes allows the fixed and movable clamping molds to clamp the bathroom towel rack. The bathroom towel rack is then passed through the sealing plugs... Fixed between two adjacent clamping moving molds and clamping stationary molds, the clamping moving mold can be moved to allow the use of different sized bathroom towel racks between the clamping stationary mold and the clamping moving mold. Then, the clamping moving mold is fixed to the platform with bolts. The sealing plug has threads and a sealing chamfer to prevent the abrasive stone from entering the cavity of the bathroom towel rack. Multiple bathroom towel racks can be clamped between two adjacent clamping stationary molds and clamping moving molds, thus enabling polishing operations on multiple bathroom towel racks at once, improving polishing efficiency.

[0016] In one possible design, the collecting structure includes multiple reciprocating lead screws that are laterally rotatably connected inside the housing. One end of each of the multiple reciprocating lead screws extends to one side of the housing, and the multiple reciprocating lead screws are connected to each other via sprockets and chains. Nut blocks are threaded onto the outer walls of each of the multiple reciprocating lead screws, and the multiple nut blocks are fixedly connected to each other via V-shaped connecting plates. The bottom of each nut block is clamped by a snap-fit ​​structure to hold debris generated during polishing.

[0017] Both sides of the nut block are fixedly connected to corrugated pipes. The ends of the two corrugated pipes that are far apart from each other are fixedly connected to the inner walls of the two sides of the box. The corrugated pipes can protect the reciprocating screw and prevent the grinding stone from affecting the fit between the reciprocating screw and the nut block. As the reciprocating screw rotates, the nut block drives the magnet to move back and forth along the bottom inner wall of the box. The magnet can then attract the debris generated during the polishing process, which not only makes it easy to recycle and reuse the debris later, but also prevents the debris from affecting the polishing operation of the grinding stone on the bathroom towel rack.

[0018] In one possible design, the stone-discharging structure includes an outlet located at the bottom of the housing. A sealing plate for closing the outlet is engaged within the outlet. Multiple slots are provided on both sides of the sealing plate, and trapezoidal pins are slidably connected within these slots. A third spring is fixedly connected to one end of each trapezoidal pin, and the other end of the third spring is fixedly connected to the inner wall of one side of the slot. Multiple grooves that mate with the trapezoidal pins are provided on the inner walls of the outlets on opposite sides. Multiple support plates for supporting the sealing plate are slidably connected to the bottom of the housing. Multiple limiting blocks for limiting the position of the support plates are fixedly connected to the bottom of the housing. A common connecting vertical plate is fixedly connected to the top of the multiple support plates. The engagement of the trapezoidal pins with the grooves initially closes the outlet, and the support plates support the sealing plate, preventing it from falling off under the weight of the grinding stones.

[0019] In one possible design, the snap-fit ​​structure includes a groove within the nut block, with two sliders slidably connected to the top of the groove. The magnet has two L-shaped slots at its top, and the bottom ends of the sliders extend into these L-shaped slots. A sliding rod slides through one inner wall of the groove, and a retaining ring is fixedly fitted onto the outer wall of the sliding rod to limit its movement. One end of the sliding rod is rotatably connected to two connecting rods located within the groove. The ends of the two connecting rods, which are spaced apart from each other, are rotatably connected to the two sliders. A second spring is fixedly connected to one end of the sliding rod. The other end is fixedly connected to the inner wall of the other side of the slide. The side of the slider near the second spring is fixedly connected to a trapezoidal locking pin that engages with the L-shaped slot. The elastic force of the second spring can bring the two sliders closer to each other, thereby completing the engagement connection between the nut block and the magnet. In addition, when the magnet needs to move back and forth to attract debris, the second push rod retracts. When the magnet needs to be removed, the second push rod extends into the box. During the movement of the nut block, the second push rod can abut against the sliding rod, thereby automatically releasing the engagement between the magnet and the nut block, making it convenient for staff to remove the mobile phone debris from the magnet.

[0020] In one possible design, a support plate is fixedly connected to one side of the housing, a push plate is slidably connected inside the support plate, a second push rod is fixedly connected to one side of the push plate and extends slidably into the housing, and the second push rod cooperates with the sliding rod, and an electric push rod for driving the push plate to move is fixedly connected to the top of the support plate.

[0021] A base and a base plate are fixedly connected to one side of the housing. The base plate is located above the base, and two rotating shafts are rotatably connected between the base and the base plate. The outer walls of both rotating shafts are fixedly fitted with first push rods for driving the vertical connecting plate. Sliding blocks are rotatably connected to the ends of the two first push rods that are far apart from each other, and these sliding blocks are slidably connected to the vertical connecting plate. A rotating shaft rotatably passes through the base plate. A second gear is fixedly connected to the bottom end of each rotating shaft. A first gear meshing with the second gear is fixedly fitted to the outer wall of one of the rotating shafts. The two rotating shafts are connected by two meshing spur gears. A third gear is fixedly connected to the top end of each rotating shaft. The bottom of the push plate is fixedly connected to a rack that meshes with the third gear; the output shaft of the electric push rod pushes the push plate and the second push rod to move to the left. The second push rod extends into the housing to drive the snap-fit ​​structure, releasing the snap-fit ​​between the nut block and the magnet. The push plate drives the second gear to rotate through the rack, and the second gear drives the two first push rods to rotate in opposite directions. The two first push rods begin to close and push the support plate to the right. The support plate releases its support for the closing plate and removes the closing plate from the outlet. At this time, the grinding stones in the housing flow out. Then, the reciprocating screw drives the nut block and the magnet to move. During the movement of the magnet, the grinding stones remaining on the inner wall of the bottom of the housing can be discharged from the housing.

[0022] In one possible design, both sides of the box are fixedly connected with pin ears, and the platform slides through guide posts that cooperate with the pin ears; the platform is loaded into the box by a crane, and the guide posts can be inserted into the pin ears during the loading process to play a good guiding role.

[0023] In one possible design, the top of each of the support plates on both sides is fixedly connected to an arc-shaped top block that slides with the bottom of the box, and the bottom of the closing plate is provided with a hand groove for easy pulling of the closing plate.

[0024] In one possible design, fixing strips are fixedly connected to both sides of the housing, and air storage plates that slidably connect to the top of the platform are also connected to both sides of the housing. The bottom of the air storage plate is elastically connected to the top of the fixing strips by multiple first springs. The side of the air storage plate near the housing has multiple air jet holes for blowing off the abrasive stones attached to the surface of the bathroom towel rack, and the air jet holes are inclined at 30°-50°. The side of the air storage plate away from the housing is fixedly connected to multiple air inlet pipes. After the polishing operation is completed, the platform is lifted upward by a crane. During the upward movement of the platform, the air storage plate extends upward under the elastic force of the first springs. The blower (not shown in the figure) is started to inject air into the air storage plate. When the bathroom towel rack is detached from the housing, the air jet holes blow air downward at an angle onto the bathroom towel rack, which can blow off the abrasive stones attached to the bathroom towel rack. This avoids the loss of abrasive stones and facilitates the subsequent cleaning of the bathroom towel rack before electroplating and spraying.

[0025] The method of using the aforementioned bathroom towel rack surface grinding and polishing equipment includes the following steps:

[0026] S1. Pour the grinding stone and polishing agent into the box. Fix the bathroom towel rack between two adjacent moving and fixed clamping molds using the sealing plug. Since the moving clamping mold can move, different sizes of bathroom towel racks can be used between the fixed and moving clamping molds. Then, fix the moving clamping mold to the platform with bolts. The sealing plug has threads and a sealing chamfer to prevent the grinding stone from entering the cavity of the bathroom towel rack. Multiple bathroom towel racks can be clamped between two adjacent fixed and moving clamping molds, thus allowing multiple bathroom towel racks to be polished at once, improving polishing efficiency.

[0027] S2. Use a crane to load the platform into the box. During the loading process, guide posts can be inserted into the pin ears to provide good guidance. As the centrifugal vibrating motor starts working, the grinding stones inside the box begin to vibrate, and the platform slowly sinks until it is completely closed, officially starting the grinding and polishing of the bathroom towel rack. After a long period of grinding, the surface finish of the bathroom towel rack can reach Ra0.2 or higher. After grinding, the next process of electroplating is carried out, and the gloss after electroplating can reach the level of a mirror.

[0028] S3. During the polishing process of the bathroom towel rack, one of the reciprocating lead screws is driven to rotate by the drive motor (not shown in the figure). Multiple reciprocating lead screws are connected by a sprocket and a chain. As the reciprocating lead screws rotate, the nut block drives the magnet to move back and forth along the bottom inner wall of the box. The magnet can then attract the debris generated during the polishing process, which not only makes it easier to recycle and reuse the debris later, but also prevents the debris from affecting the polishing operation of the grinding stone on the bathroom towel rack.

[0029] S4. After the polishing work is completed, use a crane to lift the platform upward. During the upward movement of the platform, the air storage plate extends upward under the elastic force of the first spring. Start the blower (not shown in the figure) to inject air into the air storage plate. When the bathroom towel rack is detached from the box, the air jet oblique hole blows air downward towards the bathroom towel rack, which can blow off the abrasive stones attached to the bathroom towel rack. This avoids the loss of abrasive stones and makes it easier to clean the bathroom towel rack before electroplating and spraying.

[0030] S5. When too much debris is attracted to the magnet, the electric push rod is activated. The output shaft of the electric push rod pushes the push plate and the second push rod to the left. The second push rod extends into the box, and the push plate drives the second gear to rotate through the rack. The second gear drives the first gear to rotate. The two shafts are connected by a spur gear transmission. Then the two shafts drive the first push rod to rotate in opposite directions. The two first push rods begin to close and push the support plate to the right. The support plate releases its support on the closing plate and removes the closing plate from the outlet. At this time, the grinding stones in the box flow out. Then the reciprocating screw drives the nut block and the magnet to move. During the movement of the magnet, the grinding stones remaining on the inner wall of the bottom of the box can be discharged from the box.

[0031] S6. When the V-shaped connecting plate and the magnet move to the right, the sliding rod abuts against the second push rod extending into the box. The second push rod then pushes the sliding rod to move. The sliding rod pushes the slider to move to both sides through the connecting rod, releasing the slider from clamping the magnet. At this time, the magnet falls out of the box, and the magnet is collected. The debris of the bathroom towel rack attracted by the magnet is recycled.

[0032] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0033] In this invention, the clamping structure includes a fixed clamping mold fixedly connected to both sides of the bottom of the platform, and two movable clamping molds slidably connected to the bottom of the platform. Both the movable and fixed clamping molds are provided with multiple sealing plugs. Both ends of the bathroom towel rack are provided with threaded holes that mate with the sealing plugs. The bathroom towel rack is fixed between two adjacent movable and fixed clamping molds using the sealing plugs. Because the movable clamping molds are movable, different sizes of bathroom towel racks can be used with the fixed and movable clamping molds. The sealing plugs have threads and sealing chamfers to prevent abrasive stones from entering the cavity of the bathroom towel rack. Multiple bathroom towel racks can be clamped between two adjacent fixed and movable clamping molds, allowing for polishing of multiple bathroom towel racks at once, thus improving polishing efficiency.

[0034] In this invention, the outer walls of multiple reciprocating lead screws are threaded with nut blocks, and the multiple nut blocks are fixedly connected by V-shaped connecting plates. The bottom of each nut block is clamped by a snap-fit ​​structure to attract debris generated during polishing. As the reciprocating lead screws rotate, the nut blocks drive the magnet to reciprocate along the bottom inner wall of the housing. The magnet can then attract the debris generated during polishing, which not only facilitates the later recycling and reuse of the debris but also prevents the debris from affecting the polishing operation of the abrasive stone on the bathroom towel rack.

[0035] In this invention, a second push rod is fixedly connected to one side of the push plate and slides into the housing. A first push rod for driving the vertical plate to move is fixedly sleeved on the outer wall of each of the two rotating shafts. A second gear for driving one of the rotating shafts to rotate is fixedly connected to the bottom end of each rotating shaft. The two rotating shafts are connected by two meshing spur gears. The push plate and the second push rod move to the left, and the second push rod extends into the housing to drive the locking structure, releasing the locking between the nut block and the magnet. The push plate drives the second gear to rotate via a rack, and the second gear drives the two first push rods to rotate in opposite directions, pushing the support plate to the right. The support plate releases its support for the closed plate, allowing for easy recycling of debris adsorbed on the magnet surface, reducing resource consumption.

[0036] In this invention, air storage plates that slidably connect to the top of the platform are located on both sides of the housing. The side of the air storage plate closest to the housing has multiple air jet holes for blowing off the abrasive stones attached to the surface of the bathroom towel rack. The air jet holes are inclined at 30° to 50°. After the polishing operation is completed, the platform is lifted upward by a crane. The air storage plate extends upward under the elastic force of the first spring. When the bathroom towel rack is detached from the housing, the air jet holes blow air downward at an angle onto the bathroom towel rack, which can blow off the abrasive stones attached to the bathroom towel rack. This avoids the loss of abrasive stones and facilitates the subsequent cleaning of the bathroom towel rack before electroplating and spraying.

[0037] In this invention, the clamping structure allows multiple bathroom towel racks to be placed into the box at once for polishing without any blind spots. This not only improves polishing efficiency but also ensures the polishing quality of the outer layer of the bathroom towel rack. In addition, the reciprocating movement of the magnet during polishing attracts the debris generated during polishing, which not only facilitates the recycling and reuse of the debris later but also prevents the debris from affecting the polishing operation of the abrasive stones on the bathroom towel rack. Furthermore, when the bathroom towel rack is removed from the box, the abrasive stones attached to the bathroom towel rack can be blown off, thus avoiding the loss of the abrasive stones.

[0059] Example 1

[0060] Reference Figure 1 , Figure 2 and Figure 6 This embodiment of a bathroom towel rack surface grinding and polishing device includes: a base 1 and a bathroom towel rack 8. A box 2 for polishing the bathroom towel rack 8 is provided on the top of the base 1, and the box 2 and the base 1 are elastically connected by multiple large springs 3. A platform 5 for sealing the box 2 is provided on the top of the box 2, and centrifugal vibration motors 4 are fixedly connected to both ends of the box 2 by bolts. A clamping structure is provided at the bottom of the platform 5 for clamping the bathroom towel rack 8, so that multiple bathroom towel racks 8 can be polished in the later stage. A collection structure is provided in the box 2 for collecting the debris generated during the polishing process. A stone discharge structure is provided in the box 2 for discharging the grinding stones in the box 2, so that the debris can be recycled in the later stage.

[0061] Reference Figure 2 and Figure 3The clamping structure includes fixed clamping molds 6 bolted to both sides of the bottom of platform 5. Two movable clamping molds 7 are slidably connected to the bottom of platform 5, and adjacent movable clamping molds 7 and fixed clamping molds 6 are used to clamp the bathroom towel rack 8. Multiple sealing plugs 10 are provided inside both movable clamping molds 7 and fixed clamping molds 6. Both ends of the bathroom towel rack 8 are provided with threaded holes 11 that mate with the sealing plugs 10. The mating of the sealing plugs 10 with the threaded holes 11 allows the fixed clamping molds 6 and movable clamping molds 7 to clamp the bathroom towel rack 8. The bathroom towel rack 8 is then secured by the sealing plugs 10. The clamping moving mold 7 is positioned between two adjacent clamping moving molds 7 and clamping fixed molds 6. Since the clamping moving mold 7 is movable, it is possible to use different sizes of bathroom towel racks 8 by moving the clamping moving mold 7 and clamping fixed molds 6 and clamping moving molds 7. Then, the clamping moving mold 7 is fixed to the platform 5 by bolts. The sealing plug 10 has threads and sealing chamfers to prevent the abrasive stone from entering the cavity of the bathroom towel rack 8. Multiple bathroom towel racks 8 can be clamped between two adjacent clamping fixed molds 6 and clamping moving molds 7, so that multiple bathroom towel racks 8 can be polished at one time, improving polishing efficiency.

[0062] Reference Figure 7 The collecting structure includes multiple reciprocating lead screws 17 that are laterally rotatably connected within the housing 2. One end of each reciprocating lead screw 17 extends to one side of the housing 2, and the multiple reciprocating lead screws 17 are connected to each other via sprockets and chains. Nut blocks 18 are threaded onto the outer walls of each reciprocating lead screw 17, and the multiple nut blocks 18 are fixedly connected to each other via V-shaped connecting plates 19. The bottom of each nut block 18 has a snap-fit ​​structure for absorbing debris generated during polishing. Corrugated pipes 53 are fixedly connected to both sides of each nut block 18. The ends of the tubes 53 that are far apart from each other are fixedly connected to the inner walls of both sides of the box 2. The corrugated tubes 53 can protect the reciprocating screw 17 and prevent the grinding stone from affecting the fit between the reciprocating screw 17 and the nut block 18. As the reciprocating screw 17 rotates, the nut block 18 drives the magnet 20 to move back and forth along the bottom inner wall of the box 2. The magnet 20 can then attract the debris generated during the polishing process, which not only makes it easy to recycle and reuse the debris later, but also prevents the debris from affecting the polishing operation of the grinding stone on the bathroom towel rack 8.

[0063] Reference Figure 6 , Figure 10 and Figure 11The stone-discharging structure includes an outlet 28 located at the bottom of the housing 2. A sealing plate 29 for closing the outlet 28 is engaged within the outlet 28. Multiple pin slots 47 are provided on both sides of the sealing plate 29. Trapezoidal pins 48 are slidably connected within the pin slots 47. A third spring 49 is fixedly connected to one end of the trapezoidal pin 48, and the other end of the third spring 49 is fixedly connected to one side of the inner wall of the pin slot 47. Multiple grooves that cooperate with the trapezoidal pins 48 are provided on the inner walls of the opposite sides of the outlet 28. Multiple support plates 30 for supporting the sealing plate 29 are slidably connected to the bottom of the housing 2. Multiple limiting blocks 31 for limiting the support plates 30 are fixedly connected to the bottom of the housing 2 by bolts. The top of the multiple support plates 30 is fixedly connected to the same connecting vertical plate 32 by bolts. The outlet 28 can be initially closed by the engagement of the trapezoidal pins 48 and the grooves. The sealing plate 29 is supported by the support plates 30 to prevent it from falling off under the gravity of the grinding stones.

[0064] Reference Figure 8 and Figure 9 The snap-fit ​​structure includes a groove 21 set in the nut block 18. Two sliders 23 are slidably connected inside the top of the groove 21. The top of the magnet 20 is provided with two L-shaped slots 22, and the bottom ends of the sliders 23 extend into the L-shaped slots 22. A sliding rod 24 slides through one side of the inner wall of the groove 21. A retaining ring 51 is fixedly sleeved on the outer wall of the sliding rod 24 to limit its movement. One end of the sliding rod 24 is rotatably connected to two connecting rods 25 located in the groove 21. The ends of the two connecting rods 25 that are far apart from each other are rotatably connected to the two sliders 23 respectively. One end of the sliding rod 24 is fixedly connected to a second spring 26, and the other end of the second spring 26 is connected to the other side of the groove 21. The inner wall of the side is fixedly connected, and the side of the slider 23 near the second spring 26 is fixedly connected by bolts to a trapezoidal locking pin 27 that engages with the L-shaped locking slot 22; the elastic force of the second spring 26 can make the two sliders 23 approach each other, thereby completing the locking connection between the nut block 18 and the magnet 20. In addition, when the magnet 20 needs to move back and forth to attract debris, the second push rod 44 retracts. When the magnet 20 needs to be removed, the second push rod 44 extends into the box 2. During the movement of the nut block 18, the second push rod 44 can abut against the sliding rod 24, thereby automatically releasing the locking between the magnet 20 and the nut block 18, making it convenient for the staff to remove the mobile phone debris from the magnet 20.

[0065] Reference Figure 10 and Figure 12A support plate 42 is bolted to one side of the housing 2. A push plate 43 is slidably connected inside the support plate 42. A second push rod 44, extending slidably into the housing 2, is bolted to one side of the push plate 43. The second push rod 44 cooperates with a sliding rod 24. An electric push rod 45 for driving the push plate 43 is bolted to the top of the support plate 42. A base 33 and a base plate 34 are bolted to one side of the housing 2. The base plate 34 is located above the base 33. Two rotating shafts 35 are rotatably connected between the base 33 and the base plate 34.

A sliding block 37 is rotatably connected to the two ends of the first push rods 36 that are far apart from each other. The sliding block 37 is slidably connected to the connecting vertical plate 32. A rotating shaft 40 rotatably passes through the base plate 34. A second gear 39 is fixedly connected to the bottom end of the rotating shaft 40. A gear 39 is fixedly sleeved on the outer wall of one of the rotating shafts 35. The first gear 38 meshes with the second gear, and the two rotating shafts 35 are connected by two meshing spur gears. The top of the rotating shaft 40 is fixedly connected to the third gear 41, and the bottom of the push plate 43 is fixedly connected to the rack 46 that meshes with the third gear 41. The output shaft of the electric push rod 45 pushes the push plate 43 and the second push rod 44 to move to the left. The second push rod 44 extends into the housing 2 to drive the snap-fit ​​structure, releasing the snap-fit ​​between the nut block 18 and the magnet 20. The push plate 43 drives the second gear 39 to rotate through the rack 46. The second gear 39 drives the two first push rods 36 to rotate in opposite directions. The two first push rods 36 begin to close and push the support plate 30 to the right. The support plate 30 releases its support for the closing plate 29 and removes the closing plate 29 from the outlet 28. At this time, the grinding stones in the housing 2 flow out. Then, the reciprocating screw 17 drives the nut block 18 and the magnet 20 to move. During the movement of the magnet 20, the grinding stones remaining on the bottom inner wall of the housing 2 can be discharged from the housing 2.

[0066] Reference Figure 10 and Figure 11 Both sides of the box body 2 are fixedly connected with pin ears 54 by bolts. The platform 5 is slidably slidably penetrated by guide posts 9 that cooperate with the pin ears 54. The platform 5 is installed into the box body 2 by a crane.

[0070] Reference Figure 1 , Figure 2 and Figure 6 This embodiment of a bathroom towel rack surface grinding and polishing device includes: a base 1 and a bathroom towel rack 8. A box 2 for polishing the bathroom towel rack 8 is provided on the top of the base 1, and the box 2 and the base 1 are elastically connected by multiple large springs 3. A platform 5 for sealing the box 2 is provided on the top of the box 2, and centrifugal vibration motors 4 are fixedly connected to both ends of the box 2 by bolts. A clamping structure is provided at the bottom of the platform 5 for clamping the bathroom towel rack 8, so that multiple bathroom towel racks 8 can be polished in the later stage. A collection structure is provided in the box 2 for collecting the debris generated during the polishing process. A stone discharge structure is provided in the box 2 for discharging the grinding stones in the box 2, so that the debris can be recycled in the later stage.

[0071] Reference Figure 2 and Figure 3 The clamping structure includes fixed clamping molds 6 bolted to both sides of the bottom of platform 5. Two movable clamping molds 7 are slidably connected to the bottom of platform 5, and adjacent movable clamping molds 7 and fixed clamping molds 6 are used to clamp the bathroom towel rack 8. Multiple sealing plugs 10 are provided inside both movable clamping molds 7 and fixed clamping molds 6. Both ends of the bathroom towel rack 8 are provided with threaded holes 11 that mate with the sealing plugs 10. The mating of the sealing plugs 10 with the threaded holes 11 allows the fixed clamping molds 6 and movable clamping molds 7 to clamp the bathroom towel rack 8. The bathroom towel rack 8 is then secured by the sealing plugs 10. The clamping moving mold 7 is positioned between two adjacent clamping moving molds 7 and clamping fixed molds 6. Since the clamping moving mold 7 is movable, it is possible to use different sizes of bathroom towel racks 8 by moving the clamping moving mold 7 and clamping fixed molds 6 and clamping moving molds 7. Then, the clamping moving mold 7 is fixed to the platform 5 by bolts. The sealing plug 10 has threads and sealing chamfers to prevent the abrasive stone from entering the cavity of the bathroom towel rack 8. Multiple bathroom towel racks 8 can be clamped between two adjacent clamping fixed molds 6 and clamping moving molds 7, so that multiple bathroom towel racks 8 can be polished at one time, improving polishing efficiency.

[0072] Reference Figure 7The collecting structure includes multiple reciprocating lead screws 17 that are laterally rotatably connected within the housing 2. One end of each reciprocating lead screw 17 extends to one side of the housing 2, and the multiple reciprocating lead screws 17 are connected to each other via sprockets and chains. Nut blocks 18 are threaded onto the outer walls of each reciprocating lead screw 17, and the multiple nut blocks 18 are fixedly connected to each other via V-shaped connecting plates 19. The bottom of each nut block 18 has a snap-fit ​​structure for absorbing debris generated during polishing. Corrugated pipes 53 are fixedly connected to both sides of each nut block 18. The ends of the tubes 53 that are far apart from each other are fixedly connected to the inner walls of both sides of the box 2. The corrugated tubes 53 can protect the reciprocating screw 17 and prevent the grinding stone from affecting the fit between the reciprocating screw 17 and the nut block 18. As the reciprocating screw 17 rotates, the nut block 18 drives the magnet 20 to move back and forth along the bottom inner wall of the box 2. The magnet 20 can then attract the debris generated during the polishing process, which not only makes it easy to recycle and reuse the debris later, but also prevents the debris from affecting the polishing operation of the grinding stone on the bathroom towel rack 8.

[0073] Reference Figure 6 , Figure 10 and Figure 11 The stone-discharging structure includes an outlet 28 located at the bottom of the housing 2.

The outlet 28 can be initially closed by the engagement of the trapezoidal pins 48 and the grooves. The sealing plate 29 is supported by the support plates 30 to prevent it from falling off under the gravity of the grinding stones.

[0074] Reference Figure 8 and Figure 9The snap-fit ​​structure includes a groove 21 set in the nut block 18. Two sliders 23 are slidably connected inside the top of the groove 21. The top of the magnet 20 is provided with two L-shaped slots 22, and the bottom ends of the sliders 23 extend into the L-shaped slots 22. A sliding rod 24 slides through one side of the inner wall of the groove 21. A retaining ring 51 is fixedly sleeved on the outer wall of the sliding rod 24 to limit its movement. One end of the sliding rod 24 is rotatably connected to two connecting rods 25 located in the groove 21. The ends of the two connecting rods 25 that are far apart from each other are rotatably connected to the two sliders 23 respectively. One end of the sliding rod 24 is fixedly connected to a second spring 26, and the other end of the second spring 26 is connected to the other side of the groove 21. The inner wall of the side is fixedly connected, and the side of the slider 23 near the second spring 26 is fixedly connected by bolts to a trapezoidal locking pin 27 that engages with the L-shaped locking slot 22; the elastic force of the second spring 26 can make the two sliders 23 approach each other, thereby completing the locking connection between the nut block 18 and the magnet 20. In addition, when the magnet 20 needs to move back and forth to attract debris, the second push rod 44 retracts. When the magnet 20 needs to be removed, the second push rod 44 extends into the box 2. During the movement of the nut block 18, the second push rod 44 can abut against the sliding rod 24, thereby automatically releasing the locking between the magnet 20 and the nut block 18, making it convenient for the staff to remove the mobile phone debris from the magnet 20.

[0075] Reference Figure 10 and Figure 12A support plate 42 is bolted to one side of the housing 2. A push plate 43 is slidably connected inside the support plate 42. A second push rod 44, extending slidably into the housing 2, is bolted to one side of the push plate 43. The second push rod 44 cooperates with a sliding rod 24. An electric push rod 45 for driving the push plate 43 is bolted to the top of the support plate 42. A base 33 and a base plate 34 are bolted to one side of the housing 2. The base plate 34 is located above the base 33. Two rotating shafts 35 are rotatably connected between the base 33 and the base plate 34. A first push rod 36 for driving the connecting vertical plate 32 is fixedly sleeved on the outer wall of each of the two rotating shafts 35. A sliding block 37 is rotatably connected to the two ends of the first push rods 36 that are far apart from each other. The sliding block 37 is slidably connected to the connecting vertical plate 32. A rotating shaft 40 rotatably passes through the base plate 34. A second gear 39 is fixedly connected to the bottom end of the rotating shaft 40. A gear 39 is fixedly sleeved on the outer wall of one of the rotating shafts 35. The first gear 38 meshes with the second gear, and the two rotating shafts 35 are connected by two meshing spur gears. The top of the rotating shaft 40 is fixedly connected to the third gear 41, and the bottom of the push plate 43 is fixedly connected to the rack 46 that meshes with the third gear 41. The output shaft of the electric push rod 45 pushes the push plate 43 and the second push rod 44 to move to the left. The second push rod 44 extends into the housing 2 to drive the snap-fit ​​structure, releasing the snap-fit ​​between the nut block 18 and the magnet 20. The push plate 43 drives the second gear 39 to rotate through the rack 46. The second gear 39 drives the two first push rods 36 to rotate in opposite directions. The two first push rods 36 begin to close and push the support plate 30 to the right. The support plate 30 releases its support for the closing plate 29 and removes the closing plate 29 from the outlet 28. At this time, the grinding stones in the housing 2 flow out. Then, the reciprocating screw 17 drives the nut block 18 and the magnet 20 to move. During the movement of the magnet 20, the grinding stones remaining on the bottom inner wall of the housing 2 can be discharged from the housing 2.

[0076] Reference Figure 10 and Figure 11 Both sides of the box body 2 are fixedly connected with pin ears 54 by bolts. The platform 5 is slidably slidably penetrated by guide posts 9 that cooperate with the pin ears 54. The platform 5 is installed into the box body 2 by a crane. During the loading process, the guide posts 9 can be inserted into the pin ears 54 to play a good guiding role.

[0077] Reference Figure 9 The tops of the support plates 30 on both sides are fixedly connected with arc-shaped top blocks 52 that slide with the bottom of the box body 2 by bolts. The bottom of the closing plate 29 is provided with a hand pull groove 50 for easy pulling of the closing plate 29.

[0078] Reference Figure 13 and Figure 14Both sides of the housing 2 are fixedly connected with fixing strips 12. Both sides of the housing 2 are slidably connected with air storage plates 13 that contact the top of the platform 5. The bottom of the air storage plate 13 and the top of the fixing strips 12 are elastically connected by multiple first springs 14. The side of the air storage plate 13 near the housing 2 is provided with multiple air jet holes 15 for blowing off the grinding stones attached to the surface of the bathroom towel rack 8. The air jet holes 15 are inclined at 30° to 50°. The side of the air storage plate 13 away from the housing 2 is fixedly connected with multiple air inlet pipes 16. After the polishing work is completed, the platform 5 is lifted upwards by a crane. During the upward movement of the platform 5, the air storage plate 13 extends upwards under the elastic force of the first spring 14. The blower (not shown in the figure) is started to inject air into the air storage plate 13. When the bathroom towel rack 8 is detached from the box 2, the air jet oblique hole 15 blows air downwards at the bathroom towel rack 8, which can blow off the abrasive stones attached to the bathroom towel rack 8. This avoids the loss of abrasive stones and makes it easier to clean the bathroom towel rack 8 before electroplating and spraying.

[0079] A method for using a bathroom towel rack surface grinding and polishing device includes the following steps:

[0080] S1. Pour the polishing stone and polishing agent into the box 2. Fix the bathroom towel rack 8 between two adjacent clamping moving molds 7 and clamping fixed molds 6 using the sealing plug 10. Since the clamping moving mold 7 can move, the clamping fixed mold 6 and clamping moving mold 7 can use bathroom towel racks 8 of different sizes. Then, fix the clamping moving mold 7 to the platform 5 with bolts. The sealing plug 10 has threads and sealing chamfers to prevent the polishing stone from entering the cavity of the bathroom towel rack 8. Multiple bathroom towel racks 8 can be clamped between two adjacent clamping fixed molds 6 and clamping moving molds 7, so that multiple bathroom towel racks 8 can be polished at one time, improving polishing efficiency.

[0081] S2. Use a crane to load the platform 5 into the box 2. During the loading process, guide posts 9 can be inserted into the pin ears 54 to provide good guidance. As the centrifugal vibration motor 4 starts working, the grinding stones inside the box 2 begin to vibrate. The platform 5 slowly sinks until it is completely closed, and the grinding and polishing of the bathroom towel rack 8 officially begins. After a long period of grinding, the surface finish of the bathroom towel rack 8 can reach Ra0.2 or higher. After grinding, the next process of electroplating is carried out. The gloss of the electroplated surface can reach mirror finish.

[0082] S3. During the polishing process of the bathroom towel rack 8, one of the reciprocating lead screws 17 is driven to rotate by a drive motor (not shown in the figure). Multiple reciprocating lead screws 17 are connected by a sprocket and a chain. As the reciprocating lead screw 17 rotates, the nut block 18 drives the magnet 20 to move back and forth along the bottom inner wall of the box 2. In this way, the magnet 20 can attract the debris generated during the polishing process, which not only makes it easy to recycle and reuse the debris later, but also prevents the debris from affecting the polishing operation of the grinding stone on the bathroom towel rack 8.

[0083] S4. After the polishing operation is completed, the platform 5 is lifted up by the crane. During the upward movement of the platform 5, the air storage plate 13 extends upward under the elastic force of the first spring 14. The blower (not shown in the figure) is started to inject air into the air storage plate 13. When the bathroom towel rack 8 is separated from the box 2, the jet nozzle 15 blows air downward at the bathroom towel rack 8, which can blow off the abrasive stones attached to the bathroom towel rack 8. This avoids the loss of abrasive stones and makes it easier to clean the bathroom towel rack 8 before electroplating and spraying.

[0084] S5. When too much debris is attracted to the magnet 20, the electric push rod 45 is activated. The output shaft of the electric push rod 45 pushes the push plate 43 and the second push rod 44 to move to the left. The second push rod 44 extends into the housing 2. The push plate 43 drives the second gear 39 to rotate through the rack 46. The second gear 39 drives the first gear 38 to rotate. The two rotating shafts 35 are connected by a spur gear transmission. Then, the two rotating shafts 35 drive the first push rod 36 to rotate in opposite directions. The two first push rods 36 begin to close and push the support plate 30 to the right. The support plate 30 releases its support on the closing plate 29 and removes the closing plate 29 from the outlet 28. At this time, the grinding stones in the housing 2 flow out. Then, the reciprocating screw 17 drives the nut block 18 and the magnet 20 to move. During the movement of the magnet 20, the grinding stones remaining on the bottom inner wall of the housing 2 can be discharged from the housing 2.

[0085] S6. When the V-shaped connecting plate 19 and the magnet 20 move to the right, the sliding rod 24 abuts against the second push rod 44 extending into the box 2. The second push rod 44 then pushes the sliding rod 24 to move. The sliding rod 24 pushes the slider 23 to move to both sides through the connecting rod 25, releasing the slider 23 from clamping the magnet 20. At this time, the magnet 20 falls out of the box 2. The magnet 20 is collected, and the debris of the bathroom towel rack 8 adsorbed by the magnet 20 is recycled.

[0086] However, as is well known to those skilled in the art, the working principle and wiring method of the centrifugal vibrating motor 4 and the electric push rod 45 are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Not only is it convenient to recycle the debris later, but also it can avoid the influence of the debris on the polishing work of the grinding stone on the bathroom towel rack (8); S4, when the polishing work is completed, the platform (5) is pulled up by the crane, and during the upward movement of the platform (5), the air storage plate (13) extends upward under the elastic force of the first spring (14), the air blower is started to inject air into the air storage plate (13), and when the bathroom towel rack (8) is separated from the box (2), the air injection inclined hole (15) blows air obliquely downward to the bathroom towel rack (8), which can blow off the grinding stone attached to the bathroom towel rack (8), avoiding the loss of the grinding stone and facilitating the cleaning of the bathroom towel rack (8) for electroplating and spraying later; S5, when the magnet (20) adsorbs too much debris, the electric push rod (45) is started, the output shaft of the electric push rod (45) drives the push plate (43) and the second push rod (44) to move to the left side, the second push rod (44) extends into the box (2), and the push plate (43) drives the second gear (39) to rotate through the rack (46), the second gear (39) drives the first gear (38) to rotate, the two shafts (35) are connected in transmission through the spur gears, and then the two shafts (35) drive the first push rod (36) to rotate towards each other, the two first push rods (36) start to close and push the supporting plate (30) to the right side, the supporting plate (30) releases the support of the closing plate (29), and the closing plate (29) is taken out from the outlet (28). At this time, the grinding stone in the box (2) flows out, and then the reciprocating screw (17) drives the nut block (18) and the magnet (20) to move, and the magnet (20) can discharge the residual grinding stone from the bottom inner wall of the box (2) during the movement. S6, when the V-shaped connecting plate (19) and the magnet (20) move to the right side, the sliding rod (24) is in contact with the second push rod (44) extending into the box (2), and then the second push rod (44) pushes the sliding rod (24) to move, the sliding rod (24) pushes the sliding block (23) to move to both sides through the connecting rod (25), the clamping of the sliding block (23) on the magnet (20) is released, at this time the magnet (20) falls from the box (2), the magnet (20) is collected, and the debris of the bathroom towel rack (8) attracted by the magnet (20) is recycled.
