Description
Technical Field
[0001] This utility model relates to the field of sand polishing machine technology, and in particular to a sand polishing wheel track transmission and cleaning and decontamination structure for a sand polishing machine. Background Technology
[0002] Surface treatment of metal products typically involves sand polishing using chemical polishing slurries and abrasive polishing wheels. Since most metal products are made of iron, copper, or aluminum alloys, the chemical polishing slurries used are relatively weakly corrosive, and any residue left on the polishing wheel tends to solidify and crystallize, further affecting subsequent sand polishing operations.
[0003] The materials currently used for sand polishing are mainly high-strength titanium alloys, and the chemical polishing agents used are more corrosive and have the characteristic of easily volatilizing, solidifying, and crystallizing. Therefore, the chemical polishing agent on the surface of the sand polishing wheel should be cleaned promptly after sand polishing. However, sand polishing machines cannot automatically change and clean the sand polishing wheel, causing the polishing liquid to solidify and crystallize on the surface of the polishing wheel, even clogging the chip removal holes. This not only makes cleaning difficult but also affects the accuracy of subsequent polishing, thereby shortening the service life and effectiveness of the polishing wheel.
[0004] Therefore, it is necessary to design equipment that can automatically replace sand polishing wheels, and that allows sand polishing wheels and metal products to perform multi-axis sand polishing operations in an enclosed space, making it easier to centrally collect and recycle chemical polishing agents to ensure the smooth operation of automated sand polishing processes. Real-time cleaning of sand polishing wheels is also of great importance. Utility Model Content
[0005] This utility model provides a conveyor belt structure for conveying and cleaning the sand polishing wheel of a sand polishing machine. By cleaning the sand polishing wheel in multiple stages, it solves the problem of chemical polishing liquid solidifying and crystallizing on the surface of the sand polishing wheel, extends the service life of the sand polishing wheel, and improves the polishing effect.
[0006] The above-mentioned objective of the utility model is achieved through the following technical solution:
[0007] A sand polishing machine with a sand polishing wheel track conveyor and cleaning / decontamination structure, comprising:
[0008] A base, with a replacement area and a cleaning area defined at both ends along the length of the base;
[0009] A track drive mechanism is mounted on the base and includes a track and a first power device, wherein the first power device drives the track to rotate.
[0010] A sand polishing wheel transport mechanism includes a guide rail and a plurality of transport seats for transporting sand polishing wheels. The guide rail is disposed on the base and surrounds the outer periphery of the track. The transport seats are disposed on the guide rail and are respectively connected to the track. The track drives each transport seat to move cyclically between the replacement area and the cleaning area along the guide rail.
[0011] A cleaning mechanism is provided in the cleaning area of the base for cleaning the abrasive polishing wheel that moves into the cleaning area.
[0012] The aforementioned sand polishing machine's sand polishing wheel conveyor and cleaning / decontamination structure includes a transport seat comprising a base, on which an assembly plate is erected. A first clamping wheel and a second clamping wheel are rotatably mounted on one side of the assembly plate, with a certain gap between the first and second clamping wheels. A swing arm is pivotally connected to the other side of the assembly plate, and a third clamping wheel is rotatably mounted at the free end of the swing arm. The pivoting of the swing arm causes the third clamping wheel to swing relative to the first and second clamping wheels. The first, second, and third clamping wheels constitute a three-point clamping structure for clamping a sand polishing wheel assembly with a sand polishing wheel.
[0013] The aforementioned sand polishing machine's sand polishing wheel track conveying and cleaning / decontamination structure includes a cleaning mechanism comprising a spray device. The spray device is provided with a first conduit and a second conduit at symmetrical positions in the cleaning area. One end of the first conduit and the second conduit respectively penetrates the base and is connected to an external water source. The other ends of the first conduit and the second conduit extend horizontally along the guide rail and are located above the guide rail. The bottom of the first conduit is provided with a plurality of first nozzles spaced apart, and the bottom of the second conduit is also provided with a plurality of second nozzles spaced apart, for spraying cleaning liquid downwards.
[0014] The aforementioned sand polishing machine has a sand polishing wheel track conveying and cleaning structure, wherein the positions of each first nozzle and each second nozzle correspond to each other, and several curtains are provided parallel to each other between the first guide tube and the second guide tube to separate the cleaning area into several cleaning compartments, and the first nozzles and second nozzles that correspond to each other are separated in the same cleaning compartment.
[0015] The aforementioned sand polishing machine's sand polishing wheel track conveying and cleaning structure includes a cleaning mechanism that further comprises a brushing device. The brushing device is disposed near the end of the base and located between the first guide tube and the second guide tube. The brushing device has a brush head facing the track. The brush head can be rotated by power. When a transport seat moves to be opposite the brush head, the brush head contacts the sand polishing wheel, and the surface of the sand polishing wheel is cleaned by the rotation of the brush head.
[0016] In the aforementioned sand polishing machine's sand polishing wheel track transmission and cleaning and decontamination structure, a drive belt is provided above the brush head. The drive belt is driven to move up and down to contact the third clamping wheel of the transport seat and drive the third clamping wheel to rotate. The third clamping wheel drives the sand polishing wheel assembly to rotate together, so that the sand polishing wheel rotates in the opposite direction to the brush head.
[0017] The aforementioned sand polishing machine has a sand polishing wheel conveyor and cleaning and decontamination structure, wherein the first conduit and the second conduit are connected by a diversion pipe, and the diversion pipe is equipped with a nozzle to spray and clean the sand polishing wheel.
[0018] The aforementioned sand polishing machine has a sand polishing wheel track conveyor and cleaning and decontamination structure, wherein the base behind the brushing device is provided with a drain tank, and a drain hole is provided through the drain tank to collect the cleaning waste liquid of the cleaning area and discharge it from the drain hole.
[0019] The aforementioned sand polishing machine's sand polishing wheel track transmission and cleaning and decontamination structure includes a first power unit comprising a drive wheel and a driven wheel. The drive wheel is driven to rotate by a first drive motor, and the track is fitted around the outer periphery of the drive wheel and the driven wheel, with the drive wheel driving the track to rotate.
[0020] In summary, the beneficial technical effects of this utility model are as follows:
[0021] This invention uses a track conveyor to move the polishing wheel from the replacement area to the cleaning area. Cleaning fluid is sprayed through the first conduit, the diversion pipe, and the second conduit of the spraying device to rinse the polishing fluid off the surface of the sand polishing wheel. The polishing fluid is then brushed off the surface of the sand polishing wheel by a brushing device. After cleaning, the sand polishing wheel is rotated back to the replacement area for the next replacement. This achieves real-time cleaning of the sand polishing wheel, and the sequential cleaning ensures that the polishing fluid is completely removed, improving the effect and processing accuracy of the sand polishing wheel and extending its service life.

[0065] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.
[0066] Please see Figure 1-2 This is a preferred embodiment of the sand polishing wheel track transmission and cleaning structure of the sand polishing machine of this utility model, which mainly includes a base 1, a track transmission mechanism 2, a sand polishing wheel transport mechanism 3, and a cleaning mechanism 4, wherein:
[0067] A replacement area S1 and a cleaning area S2 are defined at both ends along the length of the base 1. The track drive mechanism 2 is mounted on the base 1 and includes a track 21 and a first power unit 22. The first power unit 22 has a drive wheel 221 and a driven wheel 222. The drive wheel 221 is driven to rotate by a first drive motor 223. The track 21 is fitted around the outer periphery of the drive wheel 221 and the driven wheel 222, and the rotation of the drive wheel 221 drives the track 21 to rotate.
[0068] The sanding wheel transport mechanism 3 includes a guide rail 31 and a plurality of transport seats 32 for transporting sanding wheels 5. The guide rail 31 is mounted on the base 1 and surrounds the outer periphery of the track 21, while each transport seat 32 is mounted on the guide rail 31 and connected to the track 21. The track 21 drives the transport seats 32 to circulate along the guide rail 31 between the replacement zone S1 and the cleaning zone S2, transporting the used sanding wheels 5 from the replacement zone S1 to the cleaning zone S2 for cleaning, and then transporting the cleaned sanding wheels 5 back to the replacement zone S1 for use in the next round of sanding operations.
[0069] Among them, such as Figure 3As shown, the transport seat 32 includes a base 321, on which an assembly plate 322 is erected. A first clamping wheel 323 and a second clamping wheel 324 are rotatably mounted on one side of the assembly plate 322, with a certain gap between the first clamping wheel 323 and the second clamping wheel 324. A swing arm 325 is pivotally connected to the other side of the assembly plate 322. A third clamping wheel 326 is rotatably mounted at the free end of the swing arm 325. The pivoting of the swing arm 325 causes the third clamping wheel 326 to swing relative to the first clamping wheel 323 and the second clamping wheel 324. The first clamping wheel 323, the second clamping wheel 324, and the third clamping wheel 326 form a three-point clamping structure for clamping a sand polishing wheel assembly 6. The first clamping wheel 323, the second clamping wheel 324, and the third clamping wheel 326 are arranged in an approximately triangular configuration in space, forming a stable three-point support. The first and second clamping wheels 323 and 324 serve as fixed support points, while the third clamping wheel 326, via the swing arm 325, can freely approach or move away from the axis of the abrasive polishing wheel assembly 6, providing ample space for clamping the abrasive polishing wheel assembly 6. The three clamping wheels form a three-point support around the abrasive polishing wheel assembly 6. When the abrasive polishing wheel assembly 6 moves axially, the first clamping wheel 323, the second clamping wheel 324, and the third clamping wheel 326 clamp the abrasive polishing wheel assembly 6 containing the abrasive polishing wheel 5, thereby stabilizing the clamping position of the abrasive polishing wheel assembly 6.
[0070] Please continue reading. Figure 1-2 As shown, the cleaning mechanism 4 is located in the cleaning area S2 of the base 1, and includes a spray device 41 and a brushing device 42. The spray device 41 has a first conduit 411 and a second conduit 412 spaced symmetrically at intervals in the cleaning area S2. One end of the first conduit 411 and the second conduit 412 respectively penetrates the base 1 and is connected to an external water source. The other ends of the first conduit 411 and the second conduit 412 extend horizontally along the guide rail 31 and are located above the guide rail 31. A plurality of first nozzles 413 are spaced apart at the bottom of the first conduit 411, and a plurality of second nozzles 414 are spaced apart at the bottom of the second conduit 412, for spraying cleaning fluid to rinse the polishing fluid on the surface of the abrasive polishing wheel 5. In this embodiment, the abrasive polishing wheel 5 is initially rinsed and then rinsed a second time through the first conduit 411 and the second conduit 412, respectively, to reduce the polishing fluid residue remaining on the surface of the abrasive polishing wheel 5.
[0071] Furthermore, the positions of each first nozzle 413 and each second nozzle 414 correspond to each other, and several curtains 415 are provided parallel to each other between the first conduit 411 and the second conduit 412 to divide the cleaning area S2 into several cleaning compartments S3, and to separate the first nozzles 413 and the second nozzles 414 that correspond to each other into the same cleaning compartment S3, thereby reducing the situation where the cleaning liquid splashes and causes the sand polishing wheel 5 to be contaminated.
[0072] The brushing device 42 is disposed near the end of the base 1 and between the first conduit 411 and the second conduit 412. The brushing device 42 has a brush head 421 facing the track 21. The brush head 421 can be driven to rotate by a motor. When the track 21 moves one of the transport seats 32 to a position opposite the brush head 421, the brush head 421 comes into contact with the polishing wheel 5, and the surface of the polishing wheel 5 is cleaned by the rotation of the brush head 421.
[0073] Furthermore, such as Figure 4-7 As shown, a drive belt 43 is provided above the brush head 421. The drive belt 43 is driven to move up and down. In this embodiment, the drive belt 43 is driven to move up and down by pneumatic rotation and oscillation, but this is not limited in this utility model. The drive belt 43 moves down to contact the third clamping wheel 326 of the transport seat 32 and rotates, thereby driving the third clamping wheel 326 to rotate. The friction of the third clamping wheel 326 drives the abrasive polishing wheel assembly 6 to rotate together, thereby causing the abrasive polishing wheel 5 to rotate relative to the brush head 421. Through the above structure, the abrasive polishing wheel 5 and the brush head 421 rotate relative to each other. They can rotate in the same direction but at different speeds. Preferably, they rotate in opposite directions to increase their relative movement speed and more efficiently remove the polishing liquid from the surface of the abrasive polishing wheel 5.
[0074] The first conduit 411 and the second conduit 412 are connected by a branch pipe 416. The branch pipe 416 is equipped with a nozzle 417 located above the brush head 421 for cleaning the abrasive polishing wheel 5 and rinsing off the polishing liquid, achieving a better cleaning effect. A drain trough 11 is also provided on the base at the rear of the brushing device 42. The drain trough 11 is recessed in the base 1 and has a drain hole 12 running through it to collect the cleaning waste liquid in the cleaning zone S2 and discharge it from the drain hole 12.
[0075] For practical use of this utility model comprised of the aforementioned components, please refer to [link / reference needed]. Figure 1-2 As shown, after the used abrasive polishing wheel 5 is replaced manually or automatically by the equipment, it is placed together with the abrasive polishing wheel assembly 6 in the transport seat 32 of the replacement area S1, and the abrasive polishing wheel assembly 6 is clamped by the third clamping wheel 326, the first clamping wheel 323, and the second clamping wheel 324. The first power unit 22 drives the track 21 to move the transport seat 32 along the guide rail 31 into the cleaning area S2. Each of the first nozzles 413 of the first conduit 411 sprays cleaning fluid, and the abrasive polishing wheel is rinsed multiple times as it moves to remove the polishing fluid that has not yet solidified on the surface, completing the initial cleaning.
[0076] Please see Figure 4-7As shown, the transport seat 32 then moves the polishing wheel 5 to the brushing device 42. When the polishing wheel 5 comes into contact with the brush head 421, the drive belt 43 moves downward to contact the third clamping wheel 326 of the transport seat 32 and rotates, driving the third clamping wheel 326 to drive the polishing wheel assembly 6 to rotate, forcing the polishing wheel 5 to rotate. The brush head 421 is also driven to rotate synchronously, removing the solidified polishing liquid from the surface of the polishing wheel 5, and spraying cleaning liquid through the diversion pipe 416 to clean the surface of the polishing wheel 5, thus completing the deep cleaning.
[0077] The transport seat 32 moves further below the second conduit 412 for a second cleaning to ensure that the polishing liquid on the surface of the abrasive polishing wheel 5 is completely cleaned. After the second cleaning is completed, the transport seat 32 returns to the replacement area S1, and the cleaned abrasive polishing wheel 5 can be used for the next abrasive polishing operation, while the replaced abrasive polishing wheel 5 continues to repeat the above operation to complete the cleaning in sequence.
[0078] In summary, the sand polishing wheel track transmission and cleaning / decontamination structure of this utility model achieves the following improvements:
[0079] First, automated cleaning; This utility model uses a structure design where a conveyor belt drives the transport seat to move, so that the transport seat moves the sand polishing wheel from the replacement area to the cleaning area. After cleaning, the wheel returns to the replacement area to replace the used sand polishing wheel and clean it, thus realizing a real-time automated cyclic cleaning of the sand polishing wheel.
[0080] Secondly, it extends the service life of the sand polishing wheel. This utility model first uses a first conduit to rinse the sand polishing wheel in the cleaning area, then uses a brushing device to deeply clean the sand polishing wheel, and then uses a second conduit to rinse the sand polishing wheel a second time. This ensures that the polishing liquid on the surface of the sand polishing wheel is completely removed without any residue, and it can be directly used for the next sand polishing operation. This effectively removes the polishing liquid remaining on the surface of the sand polishing wheel, ensures the processing accuracy and efficiency of the sand polishing wheel, and extends its service life.
[0081] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
