Description

Technical Field

[0001] The present invention relates to the field of stainless steel water basin processing, and particularly to a universal grinding machine for processing stainless steel water basins. Background Art

[0002] Due to advantages such as being strong, durable, having a smooth surface, not being easily stained with dirt, and having good corrosion resistance, stainless steel water basins are widely used in modern household kitchens.

[0003] During the process of processing kitchen stainless steel water basins (i.e., stainless steel sinks), it is necessary to polish their surfaces to remove burrs and scratches and make the sink surfaces smoother. However, in actual operation, when manually using automated equipment to polish stainless steel sinks, the flat surfaces and corners of the sinks are often polished one by one. Since the number of flat surfaces and corners that need to be polished on the sink is relatively large, polishing them one by one manually has a low efficiency, resulting in a low overall production efficiency of the sink. Moreover, when polishing different parts (such as flat surfaces and corners) on the inner and outer sides of the stainless steel sink, due to different polishing angles, different polishing equipment often needs to be replaced, which not only reduces the overall polishing efficiency but also increases the complexity of the operation. In addition, during the polishing process, it is also necessary to manually adjust the position of the sink repeatedly, further increasing the tediousness of the operation and being unfavorable to the improvement of the overall processing efficiency.

[0004] In summary, the present application proposes a universal grinding machine for processing stainless steel water basins to improve the above-mentioned technical problems. Summary of the Invention

[0039] It further includes a fixing plate 113, a micro motor 114, a bidirectional electric telescopic rod 115 and an L-shaped limiting plate 116; two fixing plates 113 are fixedly connected to the two connecting plates 8 in the middle; each fixing plate 113 is rotatably connected with a bidirectional electric telescopic rod 115 through a hinge plate; each fixing plate 113 is fixedly connected with a micro motor 114, and the output shaft of the micro motor 114 is fixedly connected with the hinge plate; the two telescopic parts of each bidirectional electric telescopic rod 115 are fixedly connected with an L-shaped limiting plate 116.

[0040] The fixed adjustment unit includes an electric push rod three 121, a cover plate 122, an electric push rod four 123, an electric push rod five 124, a pressing plate 125, a DD motor two 126, an electric turntable 127, an electric push rod six 128 and an electric suction cup 129; Two electric push rods three 121 are fixedly connected to the front side and the rear side of the processing chamber 3 respectively; The telescopic parts of all the electric push rods three 121 are fixedly connected to a cover plate 122, and the cover plate 122 is slidably connected to the mounting frame 2; The cover plate 122 is slidably connected to two electric push rods four 123 through sliders; The cover plate 122 is fixedly connected with a plurality of electric push rods five 124, and the telescopic parts of the electric push rods five 124 are fixedly connected to the sliders connected to the adjacent electric push rods four 123; Each telescopic part of the electric push rod four 123 is fixedly connected to a DD motor two 126; Each rotating part of the DD motor two 126 is fixedly connected to a pressing plate 125; An electric turntable 127 is fixedly connected to the middle of the cover plate 122; The rotating part of the electric turntable 127 is fixedly connected to an electric push rod six 128; The telescopic part of the electric push rod six 128 is fixedly connected to an electric suction cup 129.

[0041] The surface of the pressing plate 125 is set as a rough surface, which can increase the friction with the water tank 100 in contact and improve the clamping effect.

[0042] The size of the cover plate 122 is similar to that of the processing chamber 3. When the cover plate 122 drives the water tank 100 to move into the processing chamber 3, the cover plate 122 can block and seal the right side of the processing chamber 3, so that the water tank 100 is polished and processed in a closed space, thus preventing the debris generated by polishing from splashing everywhere and affecting the surrounding environment.

[0043] The moving unit includes an electric guide rail 101, a moving block 102 and a hydraulic push rod 103; The electric guide rail 101 is fixedly connected to the right side of the mounting plate 4; Four moving blocks 102 are slidably connected to the electric guide rail 101; Each moving block 102 is fixedly connected with two hydraulic push rods 103, and the telescopic parts of the two hydraulic push rods 103 on the same moving block 102 are respectively fixedly connected to the adjacent connecting plates 8; All the hydraulic push rods 103 penetrate through the partition plate 5 to the right, and a plurality of sliding grooves for avoiding the up and down movement of the hydraulic push rods 103 are opened on the partition plate 5.

[0044] Considering that when manually using an automated device to polish the stainless steel water tank 100, the flat surfaces and corners of the water tank 100 are often polished one by one. However, the number of flat surfaces and corners that need to be polished on the water tank 100 is relatively large, and the efficiency of manually polishing them one by one is relatively low, resulting in a low overall production efficiency of the water tank 100. In view of this, the present invention proposes a universal grinding machine for processing stainless steel basins, and the specific operation is as follows;

[0045] First, manually place the sink 100 to be polished on the left side of the cover plate 122, with the opening of the sink 100 facing the cover plate 122. Then, synchronously control all the electric push rods five 124 to drive the corresponding electric push rods four 123 and the pressing plate 125 to move towards the sink 100, and clamp and fix the sink 100 through the pressing plate 125. Then, control the electric push rod three 121 to drive the cover plate 122 and the fixed sink 100 to move to the left until the cover plate 122 contacts the right side of the processing chamber 3. Then, control the electric push rod four 123 to drive the sink 100 to move to the left until the sink 100 contacts the polishing belt 11. At this time, the sink 100 is away from the cover plate 122. Then, control the moving blocks 102 at the uppermost and lowermost positions to drive the connected parts to move away from each other on the electric guide rail 101 until the uppermost and lowermost movable rollers 10 move above and below the sink 100 respectively. Then, control the hydraulic push rod 103 to drive the movable roller 10 to move to the right. The movable roller 10 drives the polishing belt 11 to move until the movable roller 10 moves to the right end of the sink 100 and the L-shaped clamping plate 112 contacts the sink 100. Then, control the electric push rod two 111 to drive the L-shaped clamping plate 112 to move downwards to press down the polishing belt 11 so that it fits the surface of the sink 100. Then, control all the hydraulic push rods 103 in the middle to drive the corresponding movable rollers 10 to move to the right. The movable roller 10 drives the polishing belt 11 to move until the movable roller 10 in the middle contacts the right side surface of the sink 100, as shown in the left figure in Figure 12 Figure 2. Thus, the polishing belt 11 is fully attached to the right side surface, upper side surface, and lower side surface of the sink 100. Then, control the driving roller 7 to rotate and control the DD motor one 9 to drive the movable roller 10 to rotate, and drive the polishing belt 11 to rotate clockwise when viewed from the front through the driving roller 7 and the movable roller 10, so as to polish the contact part between the polishing belt 11 and the sink 100. In this way, by deforming the polishing belt 11 to adapt to multiple surfaces to be polished of the sink 100 and the edges and corners between the polished surfaces, the rapid polishing of the sink 100 is realized, which is different from the existing automated polishing equipment used manually and improves the polishing efficiency.

[0046] It should be noted here that during the process of controlling the movement of the movable roller 10, synchronously control the electric push rod one 6 to drive the driving roller 7 to move to adjust the tension of the polishing belt 11 and ensure the normal use of the polishing belt 11.

[0047] It should be noted here that during the polishing process, control the electric push rod five 124 to drive the corresponding pressing plate 125 to move back and forth, so as to drive the sink 100 to move back and forth during the polishing process, so as to fully polish the right side surface, upper side surface, and lower side surface of the sink 100 and the corresponding edges and corners.

[0048] After the right side, upper side, and lower side of the water tank 100 are polished, control the electric push rod three 121 to drive the cover plate 122 and the water tank 100 to move rightward and reset. Then, control the electric push rod six 128 to drive the electric suction cup 129 to move leftward until the electric suction cup 129 contacts the inner side of the water tank 100, and control the electric suction cup 129 to adsorb the water tank 100. Then, control the electric push rod five 124 to drive the pressing plate 125 away from the water tank 100 to stop fixing the water tank 100. At this time, the water tank 100 is fixed on the electric suction cup 129. Then, control the electric turntable 127 to drive the electric suction cup 129 and the fixed water tank 100 to rotate 90 degrees, so that the unpolished front side and rear side of the water tank 100 rotate to the upper side and the lower side. Then, control the electric push rod five 124 to drive the pressing plate 125 to move and clamp and fix the rotated water tank 100. Then, perform the same operation as above to make the movable roller 10 drive the abrasive belt 11 to fit the right side, upper side, lower side, and corresponding edges of the rotated water tank 100, and polish the right side, upper side, lower side, and corresponding edges of the rotated water tank 100 through the transmission of the abrasive belt 11, so as to complete the polishing of the outer side of the water tank 100. However, when polishing the rotated water tank 100, its right side will be polished repeatedly, resulting in over-polishing in this area, which will affect the production quality of the overall water tank 100. Therefore, when the water tank 100 rotates and before its right side contacts the abrasive belt 11, first control the micro motor 114 on the fixing plate 113 to drive the bidirectional electric telescopic rod 115 and the L-shaped limiting plate 116 to rotate 90 degrees. And during the rotation of the L-shaped limiting plate 116, control the bidirectional electric telescopic rod 115 to drive the corresponding two L-shaped limiting plates 116 to move away from each other, so that the distance between the two L-shaped limiting plates 116 is greater than the width of the abrasive belt 11. When the L-shaped limiting plate 116 rotates, then control the bidirectional electric telescopic rod 115 to drive the corresponding two L-shaped limiting plates 116 to move towards each other to limit the abrasive belt 11 between the two L-shaped limiting plates 116. During the subsequent polishing process, control the hydraulic push rods 103 at the uppermost and lowermost positions to drive the corresponding movable rollers 10 to move, and then control the hydraulic push rods 103 in the middle to drive the corresponding movable rollers 10 and the L-shaped limiting plates 116 to move away from the water tank 100. The L-shaped limiting plates 116 drive the abrasive belt 11 to move, as shown in Figure 12 the right figure in the middle, so that the abrasive belt 11 does not contact the right side of the rotated water tank 100, thereby avoiding repeated polishing and ensuring the polishing effect of the overall water tank 100.

[0049] Meanwhile, when grinding different parts (such as flat surfaces and edges) on the inner and outer sides of the stainless-steel sink 100, different grinding equipment often needs to be replaced due to different grinding angles and shapes. This not only reduces the overall grinding efficiency but also increases the complexity of the operation. Therefore, after the grinding of the outer side of the sink 100 is completed, control the cover plate 122 to drive the sink 100 to move rightward and reset. Then, control the sixth electric push rod 128 to drive the electric suction cup 129 to move and reset. Next, control the second DD motor 126 to drive the pressing plate 125 and the fixed sink 100 to rotate 180 degrees, turning the sink 100 over so that the opening of the sink 100 faces away from the cover plate 122. Then, control the cover plate 122 to drive the sink 100 to move leftward until the cover plate 122 contacts the processing bin 3. Then, control the fourth electric push rod 123 to drive the sink 100 to move into contact with the grinding belt 11. Next, control the two middle moving blocks 102 to drive the corresponding movable rollers 10 to move so that they are respectively flush with the upper and lower surfaces inside the sink 100. Then, control the corresponding hydraulic push rods 103 to drive the two middle movable rollers 10 to move rightward until the movable rollers 10 contact the right inner surface of the sink 100. The movable rollers 10 drive the grinding belt 11 to move so that the grinding belt 11 fits against the right inner surface of the sink 100. Then, control the upper and lower moving blocks 102 to drive the corresponding movable rollers 10 to move above and below the sink 100 respectively. Next, control the corresponding hydraulic push rods 103 to drive the upper and lower movable rollers 10 to move rightward. The upper and lower movable rollers 10 drive the grinding belt 11 to move until the L-shaped clamping plate 112 contacts the sink 100, as Figure 13 shown, so that the grinding belt 11 fully fits and contacts the three inner surfaces of the sink 100 and the corresponding edges. Then, control the transmission of the grinding belt 11 to simultaneously grind the three inner surfaces of the sink 100 and the corresponding edges. The subsequent operations are the same as above. Rotate the sink 100 through the electric turntable 127 and the electric suction cup 129 to grind other parts inside the sink 100. In this way, by rotating the sink 100 through the electric turntable 127 and the electric suction cup 129 and driving the grinding belt 11 to move into contact with the inner side of the sink 100 through the two middle movable rollers 10, the inner parts of the sink 100 can be ground simultaneously, improving the overall grinding efficiency.

[0050] Considering that when the water tank 100 is polished, the debris generated by polishing will splash everywhere, affecting the surrounding environment and easily endangering the physical safety of the surrounding staff (staff inhalation); in this regard, the size of the cover plate 122 is set to be similar to the size of the processing chamber 3. When the cover plate 122 drives the water tank 100 to move and contact the processing chamber 3, the cover plate 122 can block and seal the right side of the processing chamber 3, so that the water tank 100 is polished in a closed space, thereby preventing the debris generated by polishing from splashing everywhere and affecting the surrounding environment.

[0051] Example 2: On the basis of Example 1, referring to Figure 1 、 Figure 5 、 Figure 10 and Figure 11 as shown, it further includes an air supply pipe 201, a round pipe 202 and a blowing pipe 203; the processing chamber 3 is fixedly connected with the air supply pipe 201, and the air supply pipe 201 is communicated with an external pump; the air supply pipe 201 is communicated with two round pipes 202, and the round pipe 202 is fixedly connected with the left side surface of the partition plate 5; the round pipe 202 is communicated with a plurality of blowing pipes 203, the blowing pipes 203 penetrate through the partition plate 5, and the blowing pipes 203 are arranged to incline downward toward the outside of the polishing belt 11.

[0052] It further includes a cleaning roller 204; the cleaning roller 204 is rotatably connected to the inner wall of the processing chamber 3, the cleaning roller 204 contacts the polishing belt 11, and the cleaning roller 204 is composed of a motor and a roller. Brushes for cleaning are arranged on the roller, and the motor is used to drive the roller to rotate.

[0053] It further includes a driving motor 131; the workbench 1 is fixedly connected with the driving motor 131, the output shaft of the driving motor 131 is fixedly connected with the mounting frame 2, and the mounting frame 2 is rotatably connected with the workbench 1.

[0054] It further includes a suction pipe 211, a first suction pipe 212 and a second suction pipe 213; the processing chamber 3 is fixedly connected with the suction pipe 211, and the suction pipe 211 is communicated with an external suction mechanism; the suction pipe 211 is communicated with a plurality of first suction pipes 212, and the first suction pipes 212 are located below the cleaning roller 204; the suction pipe 211 is communicated with a plurality of second suction pipes 213, and the second suction pipes 213 penetrate through the partition plate 5.

[0055] On the basis of the above-mentioned Embodiment 1, during the grinding process of the grinding belt 11, the generated debris is likely to fall onto the grinding belt 11. After long-term accumulation, it is likely to affect the normal use of the grinding belt 11. Therefore, when the grinding belt 11 is working, control an external pump to introduce gas into the air supply pipe 201. The gas in the air supply pipe 201 blows out from the air blowing pipe 203 through the round pipe 202. By continuously blowing air through the air blowing pipe 203, the situation of debris remaining on the inner side surface of the grinding belt 11 is reduced. Moreover, the air blowing pipe 203 is arranged to be inclined downward toward the outside of the grinding belt 11. By blowing air outward through the air blowing pipe 203 inclined downward toward the outside of the grinding belt 11, the debris falling on the inner side surface of the grinding belt 11 can also be blown out, further reducing the debris remaining on the inner side surface of the grinding belt 11, which is beneficial to the normal use of the grinding belt 11. And, during the working process of the grinding belt 11, control the cleaning roller 204 to rotate to clean the outer surface of the grinding belt 11 and clean the debris attached to its surface, so as to ensure the grinding effect of the grinding belt 11, avoid the debris remaining and attaching to the surface of the grinding belt 11, and reduce its grinding effect on the water tank 100. And when the debris generated by grinding is blocked by the shielding cover plate 122, the debris splashes in the processing chamber 3, which is not conducive to subsequent cleaning. Therefore, during grinding, control an external suction mechanism to suck air through the suction pipe 211 and the second suction pipe 213. The second suction pipe 213 sucks away the debris generated by grinding, and cooperate with the air blowing pipe 203 to blow the debris downward, so that the second suction pipe 213 can suck it away, improving the cleaning effect of the debris. At the same time, through the first suction pipe 212, the debris cleaned by the cleaning roller 204 can be sucked away, and the debris generated by grinding is fully removed, facilitating subsequent cleaning. And, when grinding the inner side surface of the water tank 100, control the driving motor 131 to drive the mounting frame 2 and the processing chamber 3 on the mounting frame 2 to rotate upward, making the whole in an inclined state, so that when grinding the inner side surface of the water tank 100, it is convenient for the debris to fall, avoiding the debris generated during its grinding being easily retained inside the water tank 100 and difficult to be taken out.
