Description

Technical Field

[0001] This utility model relates to the technical field of powder spreading devices, and in particular to a powder spreading device for ceramic sintering. Background Technology

[0002] Ceramics are products made from clay and other materials and fired at high temperatures. They have a delicate texture, warm color, and both practical and artistic value. When firing ceramics, a powder spreading device is needed to add ceramic powder raw materials into the mold box before firing.

[0003] The above-mentioned and existing technologies have the following defects: When using the powder spreading device, the material pump is controlled to add an appropriate amount of ceramic powder raw material to the mold box. However, during this process, the ceramic powder raw material is difficult to be evenly distributed in the mold box, which makes it easy for the fired ceramic products to have cavities or cracks, affecting the quality of the ceramic products.

[0004] Therefore, a powder spreading device for ceramic sintering is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that ceramic powder raw materials are difficult to distribute evenly in the mold box, which leads to the easy occurrence of cavities or cracks in the fired ceramic products. Therefore, a powder spreading device for ceramic sintering is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a powder spreading device for ceramic sintering, comprising an operating table, a material pump fixedly mounted on the upper surface of the operating table, a material suction pipe fixedly connected to the inlet end of the material pump, a material spreading pipe fixedly connected to the discharge end of the material pump, a fixing plate fixedly mounted on the upper surface of the operating table, a material spreading box slidably connected to the inner wall of the fixing plate, a mold box slidably connected to the inner wall of the material spreading box, a motor fixedly mounted on the upper surface of the operating table, a hexagonal prism fixedly mounted at the output end of the motor, an L-shaped plate fixedly mounted on the outer wall of the material spreading box, the hexagonal prism slidably connected to the L-shaped plate, a spring fixedly mounted on the outer wall of the material spreading box, the spring being fixedly connected to the operating table, an electric push rod fixedly mounted on the outer wall of the material spreading box, a pressure plate fixedly mounted at the output end of the electric push rod, and the pressure plate abutting against the outer wall of the mold box.

[0007] The effect achieved by the above components is as follows: through the cooperation of components such as motor, material box, spring, hexagonal prism and L-shaped plate, when ceramic powder raw material is added into the mold box, the material box can continuously slide back and forth along the inner wall of the fixed plate, thereby causing the mold box to vibrate, and thus making the ceramic powder raw material evenly distributed in the mold box, improving the quality of the fired ceramic products.

[0008] Preferably, a limiting rod slides through the material box, and the limiting rod is fixedly connected to the pressure plate.

[0009] The effect achieved by the above components is that the movement of the pressure plate will cause the limit rod to slide, and the limit rod can restrict the movement path of the pressure plate.

[0010] Preferably, a round rod is fixedly mounted on the outer wall of the material box, and a scraper is slidably sleeved on the circumferential surface of the round rod, and the scraper is slidably connected to the upper surface of the mold box.

[0011] The effect achieved by the above components is that the scraper slides along the circumference of the round rod, and when the scraper slides along the upper surface of the mold box, the scraper can scrape off the excess ceramic powder material.

[0012] Preferably, the surface of the material box has several through holes, and the lower surface of the operating table is fixedly connected to a central frame.

[0013] The effect achieved by the above components is that after excess ceramic powder material falls from the mold box, it will fall into the concentration frame through the through hole, and the concentration frame can reduce the distribution range of the ceramic powder material.

[0014] Preferably, the lower end of the central frame is slidably fitted with a retaining sleeve.

[0015] The effect achieved by the above-mentioned components is that the sleeve can prevent ceramic powder raw materials from being spilled directly from the collection box onto the ground, thus preventing waste.

[0016] Preferably, the ferrule is internally threaded with a bolt, which passes through the ferrule and abuts against the outer wall of the central frame.

[0017] The effect achieved by the above components is that when the bolt is rotated and pressed against the outer wall of the central frame, it restricts the position of the ferrule.

[0018] Preferably, a traction rope is fixedly fitted to the outer wall of the sleeve, and the traction rope is fixedly connected to the central frame.

[0019] The effect achieved by the above components is that the traction rope can prevent the ferrule from being lost.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by using components such as a motor, a material distribution box, a spring, a hexagonal prism, and an L-shaped plate, when ceramic powder is added to the mold box, the material distribution box can continuously slide back and forth along the inner wall of the fixed plate, thereby causing the mold box to vibrate. This results in the ceramic powder being evenly distributed within the mold box, improving the quality of the fired ceramic products. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-4 As shown, this utility model provides a powder spreading device for ceramic sintering, including an operating table 1. A material pump 2 is fixedly mounted on the upper surface of the operating table 1. A material extraction pipe 4 is fixedly connected to the inlet end of the material pump 2, and a material spreading pipe 3 is fixedly connected to the discharge end of the material pump 2. A fixing plate 5 is fixedly mounted on the upper surface of the operating table 1. A material spreading box 6 is slidably connected to the inner wall of the fixing plate 5. A mold box 7 is slidably connected to the inner wall of the material spreading box 6. A motor 8 is fixedly mounted on the upper surface of the operating table 1. A hexagonal prism 9 is fixedly mounted on the output end of the motor 8. The outer wall of the material spreading box 6... An L-shaped plate 10 is fixedly mounted, and a hexagonal prism 9 is slidably connected to the L-shaped plate 10. A spring 11 is fixedly mounted on the outer wall of the material distribution box 6 and is fixedly connected to the operating table 1. An electric push rod 14 is fixedly mounted on the outer wall of the material distribution box 6, and a pressure plate 15 is fixedly mounted on the output end of the electric push rod 14. The pressure plate 15 abuts against the outer wall of the mold box 7. A limit rod 16 slides through the material distribution box 6 and is fixedly connected to the pressure plate 15. When the pressure plate 15 moves, it will drive the limit rod 16 to slide. The limit rod 16 can restrict the movement path of the pressure plate 15.

[0030] A round rod 12 is fixedly mounted on the outer wall of the material distribution box 6. A scraper 13 is slidably fitted on the circumferential surface of the round rod 12. The scraper 13 is slidably connected to the upper surface of the mold box 7. When the scraper 13 slides along the circumferential surface of the round rod 12, it can scrape off excess ceramic powder material. Several through holes 17 are opened on the surface of the material distribution box 6. A collection frame 18 is fixedly connected to the lower surface of the operating table 1. After excess ceramic powder material falls from the mold box 7, it will fall into the collection frame 18 through the through holes 17. The collection frame 18 can reduce the size of the ceramic powder material. The material is distributed within a certain range. A retaining sleeve 19 is slidably fitted at the lower end of the collection frame 18. The retaining sleeve 19 prevents the ceramic powder material from spilling directly from the collection frame 18 onto the ground, causing waste. A bolt 21 is threaded inside the retaining sleeve 19. The bolt 21 passes through the retaining sleeve 19 and abuts against the outer wall of the collection frame 18. Rotating the bolt 21 restricts the position of the retaining sleeve 19 when it abuts against the outer wall of the collection frame 18. A traction rope 20 is fixedly fitted to the outer wall of the retaining sleeve 19. The traction rope 20 is fixedly connected to the collection frame 18 and prevents the retaining sleeve 19 from being lost.

[0031] The overall working principle is as follows: When ceramic powder raw material needs to be added into the mold box 7, the extraction pipe 4 is connected to the external ceramic powder raw material silo. Then, the mold box 7 is placed into the spreading box 6. The output end of the electric push rod 14 is then extended. The output end of the electric push rod 14 will drive the pressure plate 15 to press against the outer wall of the mold box 7, thereby restricting the position of the mold box 7. The movement of the pressure plate 15 will drive the limit rod 16 to slide. The limit rod 16 can restrict the movement path of the pressure plate 15. Then, the material pump 2 is turned on, and the ceramic powder raw material will be discharged into the mold box 7 by the spreading pipe 3. At the same time, the motor 8 is turned on, and the output end of the motor 8 rotates. The movement causes the hexagonal prism 9 to rotate. The hexagonal prism 9, the L-shaped plate 10, and the spring 11 work together to make the material box 6 slide back and forth along the inner wall of the fixed plate 5, thereby causing the mold box 7 to vibrate. This makes the ceramic powder material evenly distributed in the mold box 7. After the addition is completed, the material pump 2 and the motor 8 are turned off. Then, the scraper 13 slides along the circumference of the round rod 12. When the scraper 13 slides along the upper surface of the mold box 7, the scraper 13 can scrape off the excess ceramic powder material. Then, the output end of the electric push rod 14 is controlled to retract, so that the pressure plate 15 is disengaged from the mold box 7. Then the mold box 7 can be taken out for subsequent processing.

[0032] Excess ceramic powder material falls from the mold box 7 and into the collection frame 18 through the through hole 17. At this time, the retaining sleeve 19 can prevent the ceramic powder material from spilling directly from the collection frame 18 onto the ground and causing waste. When it is necessary to discharge the ceramic powder material in the collection frame 18, turn the bolt 21. The bolt 21 will move with the thread to disengage from the collection frame 18. Then, remove the retaining sleeve 19 from the lower end of the collection frame 18, and the ceramic powder material can be discharged. At this time, the traction rope 20 can prevent the retaining sleeve 19 from being lost. After the discharge is completed, put the retaining sleeve 19 back on the lower end of the collection frame 18 and turn the bolt 21 in the opposite direction. When the bolt 21 abuts against the outer wall of the collection frame 18, it will restrict the position of the retaining sleeve 19.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
