Description

Technical Field

[0001] The invention relates to the technical field of ceramic processing, in particular to a scraping device for processing ceramic products. Background Art

[0002] During the processing of ceramic products, the scraping device is a device used to remove excess material from the edge of the blank and trim the shape and size of the product. This step is very important to ensure the quality, appearance and specification consistency of the finished product. The scraping device can be used in the production of many types of ceramic products such as pottery, stoneware and porcelain, especially on round products or products with specific edge shapes such as plates, bowls and cups.

[0003] At present, the patent with announcement number CN211891448U discloses a scraping device for ceramic product processing, including a scraping mechanism, a conveying mechanism is arranged below the scraping mechanism, a dust removal mechanism is arranged below the conveying mechanism, the conveying mechanism includes a conveying frame, a No. 1 motor, and a conveyor belt, the No. 1 motor is installed at the front of the conveying frame, the conveyor belt is installed inside the conveying frame, a placement seat is arranged on the conveyor belt, a No. 1 electric telescopic column is arranged above the placement seat, and a clamping block is installed on the No. 1 electric telescopic column. The device has a simple structure, reasonable design, low production cost, great labor saving, and is suitable for mass production. At the same time, it can effectively reduce dust and protect the health of workers.

[0004] However, the above-mentioned scraping device still has the following problems in actual use:

[0005] When scraping the edges of the formed ceramic body, it is usually necessary to place the body naturally for a period of time to allow it to reach a "leather hard" state (also known as a semi-dry body). At this time, the body is partially dry, but still has a certain degree of flexibility, which is not easy to break and easy to trim. Then the semi-dry body is placed on the turntable of the scraping device, and the excess part of the body is scraped off by the scraper (or scraping rope) on one side of the turntable.

[0006] However, the above-mentioned scraping device can only support and clamp one blank at a time, which results in that when scraping the blank, the next blank can only be placed after the scraping of the previous blank is completed and removed, resulting in low work efficiency.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] See also Figure 1-Figure 12A scraping device for processing ceramic products, comprising four support seats 12, four rotating motors 29 respectively installed inside the four support seats 12, four placement plates 30 respectively installed at the output ends of the four rotating motors 29, and a plurality of extrusion blocks 8 respectively installed on the four placement plates 30, a base 1 is arranged under the four support seats 12, a support box 2 is fixedly connected to the upper surface of the base 1, an operating cavity 201 is opened on the upper surface of the support box 2, a top plate 4 is rotatably connected to the inner wall of the top surface of the operating cavity 201, four movable openings 401 are opened through the upper surface of the top plate 4, and two support blocks 23 are fixedly connected to the inner walls of the four movable openings 401, the four support seats 12 They are respectively located in the four movable openings 401, and the lower ends of the support seats 12 are respectively fixedly connected to the two support blocks 23, a scraping mechanism is connected to one side of the outer wall of the support box 2, and the upper end of the scraping mechanism is located above one of the placement plates 30, and the bottom surface of the operating chamber 201 is connected to a power mechanism, and the output end of the power mechanism is connected to a rotating component, and the output end of the power mechanism is also connected to the middle of the top plate 4, and the other four ends of the rotating component are simultaneously connected to the lifting component, and the upper end of the lifting component is connected to four protective components, and the four protective components are respectively matched with the four support seats 12, and the upper end of the rotating component is also connected to an exhaust mechanism, and the output end of the exhaust mechanism is connected to the four protective components.

[0037] like Figures 1 to 12 As shown, the ceramic product processing scraping device of the present invention can be used in the following steps:

[0038] 1. First, place the first ceramic body on the placement plate 30 in the loading area, and then use a number of extrusion blocks 8 to restrict the body on the placement plate 30 so that it will not get loose, and then start the power mechanism through an external controller.

[0039] 2. After the power mechanism is started, the output end can rotate with the top plate 4 at the top of the operating chamber 201.

[0040] 3. As the top plate 4 rotates, the support base 12 and the placement plate 30 located in the four movable openings 401 of the top plate 4 will rotate in a clockwise direction.

[0041] 4. When the top plate 4 rotates clockwise, the blank just placed on the placement plate 30 in the loading area will be rotated to the position of the scraping area, and the scraping mechanism will be started through the external controller.

[0042] 5. After the scraping mechanism is started, the output end moves downward to match the blank on the placement plate 30, and then the rotating motor 29 located in the support seat 12 is started.

[0043] 6. After the rotating motor 29 is started, its output shaft can rotate with the placing plate 30, and during the rotation, the blank is brought into contact with the scraping mechanism, so that the excess part of the top or edge of the blank can be scraped off by the scraping mechanism.

[0044] 7. When the scraping mechanism is scraping the blank, a certain degree of dust will be generated. In order not to affect the working environment and product quality, before the rotating motor 29 is started, the exhaust mechanism located in the operating chamber 201 can be started by an external controller.

[0045] 8. After the exhaust mechanism is started, the input end can extract air from the inside of the protective component outside the placement plate 30 located in the scraping area, and then the dust generated in the scraping area can be discharged to the external designated location through the output end of the exhaust mechanism for collection and subsequent treatment.

[0046] 9. While the first blank is being scraped in the scraping area, the staff can continue to place the second blank on the placement plate 30 in the loading area and squeeze it tightly through the extrusion block 8.

[0047] 10. Then start the power mechanism again, the power mechanism will repeat the above steps, continue to rotate the second blank to the bottom of the scraping mechanism, and continue to repeat the above steps. At the same time, the first blank that has been scraped will follow the top plate 4 to rotate to the observation area.

[0048] 11. At this time, the staff in the observation area can observe whether there are defects on the first platform where the scraping is completed. If there are defects, they can mark them and rotate them once under the top plate 4. When they are rotated to the unloading area, they can take them out and discard them or rework them.

[0049] 12. Repeat the above steps and start the power mechanism for the third time. At this time, the power mechanism controls the top plate 4 to rotate again, and transfers the blanks in the observation area to the unloading area. At this time, the workers in the unloading area can scrap or rework the blanks according to the marks in the observation area (defective products). If there are no marks or the marks are normal, the blanks can be taken out and enter the next process (such as drying, shaping, finishing, etc.).

[0050] 13. At this point, the scraping process of a blank is completed. The blank can be loaded, scraped, observed (checked for defects) and unloaded without stopping the machine, thus improving work efficiency.

[0051] 14. Continuing from the above, while the power mechanism drives the top plate 4 to rotate, it also drives the rotating assembly to rotate in the operating chamber 201 of the support box 2.

[0052] 15. After the rotating assembly rotates, it can rotate with the lifting assembly, and after the lifting assembly rotates, it can lift and lower the four protective assemblies located in the four movable openings 401.

[0053] 16. As the protective components rise and fall, the four protective components will be controlled to be at different heights:

[0054] A: The protective component located in the scraping edge area is higher, which can absorb the dust generated by the scraping edge;

[0055] B: The protective components of the observation area and the loading area can be flush with or slightly higher than the surface of the placement plate 30, which can facilitate the observation and placement of the blanks and the limitation of the extrusion block 8.

[0056] C: The height of the unloading area protection assembly is lower than the surface of the placement plate 30, so that when the limit of the extrusion block 8 is released and the blank is removed from the placement plate 30, it is not easily disturbed by foreign objects.

[0057] Special mention should be made here:

[0058] 1. To facilitate the description and understanding of the above and subsequent contents, the four placement plates 30 are counted from the scraping mechanism and rotated counterclockwise to divide them into four areas, namely the scraping area, the observation area, the unloading area and the loading area.

[0059] 2. The four rotating motors 29, four movable openings 401, etc. mentioned above and below are all references. For the convenience of description and understanding, they are not limited to four, and their number can be unlimited, including the number of scraping mechanisms is not limited to one group, and can be more groups.

[0060] 3. The support base 12, placement plate 30, rotating motor 29 and several extrusion blocks 8 mentioned in the above content are all existing mature technologies, so their connection relationship, working principle, etc. are not described in detail here.

[0061] 4. The external controller mentioned in the above content is also a prior art, so it will not be described in detail.

[0062] As a preferred solution of the present invention, the power mechanism includes a power motor 14 and a center rod 3. A motor cavity 101 is opened on the upper surface of the base 1. The outer wall of the power motor 14 is fixedly connected to the inner wall of the motor cavity 101. The output shaft of the power motor 14 is fixedly connected to the lower end of the center rod 3. The upper end of the center rod 3 passes through the bottom surface of the support box 2, the middle of the rotating assembly and the middle of the top plate 4, and the outer wall of the upper end of the center rod 3 is fixedly connected to the inner wall of the top plate 4 at the penetration point, and the outer wall of the center rod 3 is rotatably connected to the inner wall of the support box 2 at the penetration point.

[0063] More specifically, when it is necessary to control the top plate 4 to rotate, it is only necessary to turn on the power motor 14 through an external controller, and the output shaft of the power motor 14 can drive the center rod 3 to rotate. After the center rod 3 rotates, it can drive the rotating components connected to the surface and the top plate 4 to rotate together.

[0064] As a preferred embodiment of the present invention, the rotating assembly includes an inner gear ring 16, a cross plate 22, four gears 21 and four anti-slip rings 27. The middle part of the cross plate 22 is sleeved and fixedly connected to the outer wall of the center rod 3. The bottom surfaces of the other four ends of the cross plate 22 are provided with anti-slip openings 221. The four anti-slip rings 27 are respectively located in the four anti-slip openings 221, and the outer walls of the four anti-slip rings 27 are respectively rotatably connected to the inner walls of the four anti-slip openings 221. The bottom surfaces of the four anti-slip rings 27 are respectively fixedly connected to the upper surfaces of the four gears 21. The outer wall of the inner gear ring 16 is fixedly connected to the inner wall of the operating chamber 201. The four gears 21 are all meshed with the inner gear ring 16. The ends of the four lifting assemblies away from the protective assembly are respectively located inside the four gears 21, and the end of the exhaust mechanism away from the protective assembly is connected to the upper surface of the cross plate 22.

[0065] More specifically, when the center rod 3 rotates, it will rotate with the cross plate 22. After the cross plate 22 rotates, the four gears 21 located at its four corners will also rotate with the center rod 3 as the axis. At the same time, the four gears 21 will also rotate through the anti-slip ring 27 and the anti-slip opening 221 because of the engagement with the inner gear ring 16, thereby controlling the lifting and lowering of the lifting components located inside the four gears 21.

[0066] Similarly, because the air extraction mechanism is installed on the cross plate 22, when the cross plate 22 rotates, the air extraction mechanism will also rotate together.

[0067] As a preferred embodiment of the present invention, the lifting assembly includes a chassis 15, four reciprocating screw rods 19 and four rectangular rods 20. The middle part of the chassis 15 is sleeved and fixedly connected with the outer wall of the lower end of the center rod 3. The upper surface of the chassis 15 is fixedly connected to the lower ends of the four rectangular rods 20. The interiors of the four reciprocating screw rods 19 are penetrated by rectangular openings 191. The upper ends of the four reciprocating screw rods 19 respectively penetrate four gears 21 and are threadedly connected to the inner walls of the four gears 21. The ends of the four reciprocating screw rods 19 that penetrate the gears 21 are also respectively connected to four protective assemblies. The upper ends of the rectangular rods 20 are located in the rectangular opening 191, and the outer walls of the rectangular rods 20 are slidably connected to the inner walls of the rectangular opening 191.

[0068] More specifically, the reciprocating screw 19 inside the gear 21 cannot rotate due to the restriction of the rectangular opening 191 and the rectangular rod 20. Therefore, after the gear 21 rotates, it will control the reciprocating screw 19 to rise or fall, thereby achieving lifting and lowering together with the protective component at the upper end of the reciprocating screw 19.

[0069] It should be noted here that: since the lower ends of the four rectangular rods 20 are simultaneously connected to the chassis 15, when the center rod 3 rotates, the chassis 15 will also rotate together. Therefore, the four rectangular rods 20 and the four reciprocating screw rods 19 remain relatively stationary relative to the cross plate 22, so no structural conflict will occur.

[0070] As a preferred embodiment of the present invention, the protection component includes a protection box 6, a butt joint 25 and two elastic baffles 7. The bottom surface of the outer wall of the protection box 6 is fixedly connected to the upper end of the reciprocating screw rod 19, and the side wall of the protection box 6 is slidably connected to the inner wall of the movable opening 401. Slide openings 601 are opened on both sides of the protection box 6. The inner walls of the two slide openings 601 are respectively slidably connected to the outer walls of the two support blocks 23 in the same movable opening 401. The upper ends of the two elastic baffles 7 are respectively fixedly connected to the top surfaces of the two slide openings 601. The two elastic baffles 7 The lower end is fixedly connected to the upper surfaces of the two support blocks 23 respectively, one end of the docking tube 25 is fixedly connected to the lower end of the protective box 6, and the other end of the docking tube 25 is connected to the exhaust mechanism. The docking tube 25 is located below the top plate 4 and the support block 23. An exhaust cavity 603 is opened inside the protective box 6, and a plurality of ash suction holes 602 are opened on the inner side wall of the upper end of the protective box 6. The plurality of ash suction holes 602, the exhaust cavity 603, the docking tube 25 and the exhaust mechanism are connected internally, and the inner side wall of the protective box 6 is slidably connected to the outer wall of the support seat 12 and the placement plate 30.

[0071] More specifically, when the reciprocating screw rod 19 is lifted and lowered under the action of the gear 21, the protective box 6 at its upper end will be lifted and lowered together. However, the protective box 6 will not rotate due to the restrictions of the slide 601 and the support block 23, and can only slide up and down. At the same time, the vacuum mechanism is started, and the dust generated when the blank is scraped on the plate 30 inside the protective box 6 will be absorbed through the docking tube 25, the vacuum chamber 603 and the ash absorption hole 602. In order to prevent dust from flowing out from the slide 601, an elastic baffle 7 is provided between the slide 601 and the support block 23, so that this part of the dust can be blocked.

[0072] Special mention should be made here:

[0073] 1. When the vacuum mechanism is started, because the heights of the four protective components are different, at this time, except for the ash suction holes 602 on the protective box 6 in the scraping area which are located above the placement plate 30, the ash suction holes 602 of the protective boxes 6 in the other three areas are all located below the placement plate 30, so as to avoid dispersing the suction force of the ash suction holes 602 in the scraping area.

[0074] 2. When scraping the edges, some dust will not be sucked away by the dust suction holes 602, but will fall on the placement plate 30. At this time, because the top plate 4 needs to rotate the protective box 6 in the scraping area to the observation area, and the protective box 6 will be in a descending process when moving from the scraping area to the observation area, when the dust suction holes 602 move to be flush with the placement plate 30, the dust that has previously fallen on the placement plate 30 can be sucked in again.

[0075] As a preferred embodiment of the present invention, the exhaust mechanism includes an ash outlet pipe 18, an exhaust fan 24, a diversion assembly and an ash discharge assembly. The outer wall of the exhaust fan 24 is fixedly connected to the upper surface of the cross plate 22, the input end of the exhaust fan 24 is connected to one end of the diversion assembly, and the other four ends of the diversion assembly are respectively connected to four docking pipes 25. The output end of the exhaust fan 24 is fixedly connected to one end of the ash outlet pipe 18, and the other end of the ash outlet pipe 18 is connected to the ash discharge assembly. A plurality of ash outlet ports 202 are formed through the side wall of the support box 2, and the ash discharge assembly is matched and aligned with the plurality of ash outlet ports 202. The docking pipes 25, the diversion assembly, the exhaust fan 24, the ash outlet pipe 18, the ash discharge assembly and the ash outlet ports 202 are internally connected.

[0076] More specifically, when it is necessary to absorb the dust of the scraping area blank, it is only necessary to turn on the exhaust fan 24 through the external controller. After the exhaust fan 24 is started, the input end will extract dust from the exhaust chamber 603 and the ash suction hole 602 through the diversion component and the docking tube 25. The extracted dust will be discharged into the ash discharge component along the ash discharge pipe 18, and then discharged to the outside of the operating chamber 201 through the ash outlet 202. At this time, it is only necessary to set a collection box, a collection bag, etc. outside the ash outlet 202 to collect this part of the dust. It is simple and easy to operate.

[0077] Special mention should be made here:

[0078] 1. The exhaust fan 24 is an existing mature technology, so its principle and internal structure are not described in detail here.

[0079] 2. The exhaust fan 24 can be any model with strong suction power commonly used in the market, and the specific model is not limited.

[0080] As a preferred solution of the present invention, the diversion component includes a five-way pipe 28 and four exhaust pipes 26, one end of the five-way pipe 28 is fixedly connected to the input end of the exhaust fan 24, the other four ends of the five-way pipe 28 are respectively fixedly connected to one end of the four exhaust pipes 26, the other ends of the four exhaust pipes 26 are respectively fixedly connected to one end of four docking pipes 25 away from the protective box 6, the docking pipes 25, the exhaust pipes 26, the five-way pipe 28 and the exhaust fan 24 are internally connected.

[0081] More specifically, after the exhaust fan 24 is started, the input end will draw air from the inside of the four exhaust pipes 26 through the five-way pipe 28. Because except for the dust suction holes 602 in the scraping area that are exposed to the outside, the dust suction holes 602 in the other three areas are all located below the placement plate 30 and are blocked by the support seat 12. Therefore, the suction force generated by the exhaust fan 24 can only be drawn from the dust suction holes 602 in the scraping area, and the dust generated in this part can be extracted.

[0082] As a preferred solution of the present invention, the ash discharge assembly includes a connecting ring 17 and four connecting blocks 13, one end of each of the four connecting blocks 13 is fixedly connected to the inner side wall of the connecting ring 17, and the other ends of the four connecting blocks 13 are respectively fixedly connected to the four ends of the cross plate 22, and the end of the ash discharge pipe 18 away from the exhaust fan 24 passes through and is fixedly connected to the inner wall of the connecting ring 17, and the outer side wall of the connecting ring 17 is slidably connected to the inner wall of the operating chamber 201. The outer wall of the support box 2 is fixedly connected with an L-shaped cover 5, the opening of the L-shaped cover 5 faces downward, and the opening of the L-shaped cover 5 is matched and aligned with the ash outlet 202.

[0083] More specifically, the dust extracted by the exhaust fan 24 will enter the cavity between the connecting ring 17 and the support box 2 through the ash outlet pipe 18. Because of the ash outlet 202, the sucked dust in this cavity will be discharged from the ash outlet 202 to the outside of the support box 2, and then flow out from the opening under the L-shaped cover 5. Before this, it is only necessary to set a collection bag or a collection box at the opening of the L-shaped cover 5 to collect and process this part of the dust.

[0084] As a preferred solution of the present invention, the scraping mechanism includes an L-shaped bracket 9, an electric push rod 10 and a scraper 11. The lower end of the L-shaped bracket 9 is fixedly connected to the outer wall of the support box 2, and the upper end of the L-shaped bracket 9 is fixedly connected to the outer wall of the electric push rod 10. The output end of the electric push rod 10 passes through the L-shaped bracket 9 and is fixedly connected to the upper end of the scraper 11. The electric push rod 10 and the scraper 11 are located above the placement plate 30, and the electric push rod 10 and the scraper 11 are located inside the protective box 6.

[0085] More specifically, when it is necessary to scrape the edges of the blank on the placement plate 30 in the scraping area, it is only necessary to turn on the electric push rod 10 through an external controller, and the output end of the electric push rod 10 can push the scraper 11 down. When the scraper 11 descends to contact the blank, as the placement plate 30 rotates, the excess part of the blank opening or side will be scraped off by the scraper 11, and the generated dust will be sucked away by the dust suction hole 602.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
