Description

Technical Field

[0001] This utility model provides an automatic ceramic pressing device, which relates to the field of ceramic manufacturing technology. Background Technology

[0002] Pressing is one of the processes in ceramic production. It uses machinery to automatically produce ceramics instead of manual labor. Clay is poured into a plaster mold and pressed by a machine to form the ceramic into a specified size and shape.

[0003] Patent CN219075979U discloses a pressing machine. This patent describes a pressing machine where a mounting arm rotates on a support column, placing a rolling disc into a mold. A motor then drives a drive sleeve on a fixed block via a pulley assembly, causing a prism to rotate the rolling disc. The rolling disc and mold work together to press ceramics. However, this pressing machine has shortcomings in practical use. When producing different ceramic products, the required rolling disc needs to be replaced. However, the rolling disc is fixed to a prism, which is fixed to the bottom of a cylinder, making it impossible to replace the rolling disc.

[0004] Therefore, there is a need for an automatic ceramic blank pressing device that facilitates the replacement of the rolling disc. Utility Model Content

[0005] In order to overcome the shortcomings of existing pressing machines that cannot change the rolling plate when making different ceramic products, this utility model provides an automatic ceramic pressing device that facilitates the replacement of the rolling plate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic ceramic pressing device, comprising a base, a baffle, a first motor, a mold, a guide cabinet, a first mounting frame, a second motor, a screw, a support plate, a second mounting frame, a third motor, and a connecting rod. The first motor is mounted on the base, its output shaft penetrates the base, and the mold is fixedly connected to the output shaft. The baffle is fixedly connected to the base, the first mounting frame is mounted on the base, the second motor is mounted on the first mounting frame, and the screw is fixedly connected to the output shaft of the second motor. The guide cabinet is mounted on the base, and a support plate is slidably disposed within the guide cabinet. The screw is rotatably connected to the guide cabinet and threadedly connected to the support plate. The second mounting frame is mounted on the support plate, and the third motor is mounted on the second mounting frame. A connecting rod is fixedly connected to the output shaft of the third motor. The device also includes a rolling disc, a guide seat, limiting rods, and an adjusting ring. The guide seat is sleeved on the connecting rod, and the rolling disc is mounted on the guide seat. Multiple limiting rods slidably pass through the guide seat and the connecting rod, and an adjusting ring is rotatably disposed on the multiple limiting rods.

[0007] Furthermore, it also includes a first adjusting rod mounted on the support plate, a positioning sleeve slidably mounted on the first adjusting rod, a second adjusting rod slidably mounted on the positioning sleeve, a scraper fixedly connected to the second adjusting rod, and positioning screws threaded on both ends of the positioning sleeve.

[0008] Furthermore, it also includes a first guide rod mounted on the base, a push plate slidably mounted on the first guide rod, two first elastic elements for pushing the push plate wound around the first guide rod, and a pull frame mounted on the support plate.

[0009] Furthermore, the baffle has an opening on the side near the push plate.

[0010] Furthermore, it also includes a guide frame mounted on the baffle, a scraper is slidably mounted on the guide frame, a rotating shaft is rotatably mounted on the scraper, and a second guide rod is fixedly connected to both sides of the guide frame. The rotating shaft is slidably connected to the two second guide rods, and a second elastic element for pushing the rotating shaft is wound around the second guide rod. A protrusion is fixedly attached to the scraper, and the protrusion cooperates with the support plate.

[0011] Furthermore, the guide frame is equipped with J-shaped grooves.

[0012] Furthermore, a rubber sleeve is fitted onto the protrusion.

[0013] Furthermore, a support rod is fixedly connected to both the base and the guide cabinet, and the support rod is slidably connected to the support plate.

[0014] Compared with the prior art, the pressing device provided by this utility model embodiment has the following advantages: 1. By rotating the adjusting ring in both directions, each limiting rod is pulled to slide along the guide seat, so that the limiting rod clamps or disengages from the connecting rod, and the guide seat is slid off the connecting rod to replace the rolling plate, thus achieving the effect of facilitating the replacement of the rolling plate.

[0015] 2. By sliding the positioning sleeve on the first adjusting rod and the second adjusting rod on the positioning sleeve, the horizontal and vertical positions of the scraper are adjusted. The scraper scrapes off the clay adhering to the edge of the rotating mold and the rolling plate, thus achieving the effect of adjusting the scraper position and removing clay from the edge of the mold and the rolling plate.

[0016] 3. By pulling the frame, the push plate is pushed so that it slides along the first guide rod. After the clay adhering to the edge of the mold and the rolling plate is scraped off by the scraper, the clay falls into the stroke of the push plate. When the pull frame moves upward, the first elastic pusher pushes the push plate to slide back to its original position, so as to push the clay off the base and achieve the effect of cleaning the clay.

[0017] 4. By starting the third motor, the rolling disc is rotated so that it comes into contact with the scraper. The scraper then scrapes off the clay at the bottom of the rolling disc, thus removing the clay from the bottom of the disc. Attached Figure Description

Detailed Implementation

[0026] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0027] Example 1: An automatic ceramic pressing device, see reference. Figures 1-3 As shown, the system includes a base 1, a baffle 2, a first motor 3, a mold 4, a guide cabinet 5, a first mounting bracket 6, a second motor 7, a screw 8, a support plate 9, a second mounting bracket 10, a third motor 11, and a connecting rod 12. The first motor 3 is bolted to the top and bottom of the base 1. The output shaft of the first motor 3 faces upward and penetrates the base 1. The mold 4 is fixedly connected to the output shaft of the first motor 3 via a coupling. A baffle 2 for preventing clay splattering is bolted to the base 1. The first mounting bracket 6 is bolted to the middle of the rear side of the base 1. The second motor 7 is bolted to the first mounting bracket 6. A screw 8 is fixedly connected to the output shaft of the second motor 7 via a coupling. The guide cabinet 5 is welded to the rear side of the base 1. A support plate 9 is slidably installed inside the guide cabinet 5. The support plate 9 slides up and down along the guide cabinet 5. The screw 8 is rotatably connected to the guide cabinet 5 and threadedly connected to the support plate 9. The top of the support plate 9 is bolted to a second mounting bracket 10. The second mounting bracket 10 is bolted to a third motor 11. The output shaft of the third motor 11 faces downward and penetrates the support plate 9. The output shaft of the third motor 11 is fixedly connected to a connecting rod 12 via a coupling. The support plate also includes a rolling plate 13, a guide seat 14, a limiting rod 15, and an adjusting ring 16. The bottom of the connecting rod 12 is fitted with a guide seat 14. The top of the guide seat 14 is bolted to a rolling plate 13. Four limiting rods 15 slide together on the guide seat 14 and the connecting rod 12. The four limiting rods 15 are evenly distributed around the guide seat 14. An adjusting ring 16 is rotatably mounted on the four limiting rods 15.

[0028] When pressing is required, the clay is first placed into the mold 4. Then, the second motor 7 is started to drive the screw 8 to rotate, so that the support plate 9 slides down along the guide cabinet 5, causing the rolling disc 13 to press onto the clay in the mold 4. Then, the first motor 3 is started to drive the mold 4 to rotate, and the third motor 11 is started to drive the connecting rod 12 to rotate, so that the rolling disc 13 and the mold 4 rotate in opposite directions, pressing the clay into shape. When the rolling disc 13 needs to be replaced, the adjusting ring 16 is rotated to pull the limiters. The rod 15 slides along the guide seat 14 to the side away from the center, so that the limiting rod 15 is released from the clamping of the connecting rod 12. Then the guide seat 14 can be slid off the connecting rod 12 to replace the rolling plate 13. After replacing the rolling plate 13, the guide seat 14 is put into the bottom of the connecting rod 12, and the adjusting ring 16 is rotated in the opposite direction so that the adjusting ring 16 pulls and pushes the limiting rod 15 to slide towards the center of the guide seat 14, so that the limiting rod 15 is clamped and inserted on the connecting rod 12, and the rolling plate 13 is fixed.

[0029] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a first adjusting rod 17 installed on the side of the support plate 9 by means of bolt connection. A positioning sleeve 18 is slidably provided on the first adjusting rod 17, and a second adjusting rod 19 is slidably provided on the positioning sleeve 18. A scraper 20 for scraping clay is fixedly connected to the bottom of the second adjusting rod 19 by welding. Positioning screws 21 are threaded on both ends of the positioning sleeve 18. The two positioning screws 21 are used to fix the first adjusting rod 17 and the positioning sleeve 18 respectively.

[0030] During the pressing process, the clay is thrown out by centrifugal force and sticks to the edges of the mold 4 and the rolling plate 13. When the mold 4 and the rolling plate 13 rotate, their surface edges come into contact with the scraper 20, causing the sticky clay to be scraped off. The scraper 20 guides the scraped clay to the outside of the mold 4 and onto the upper surface of the base 1. When it is necessary to adjust the position of the scraper 20, the two positioning screws 21 are rotated to disengage the two positioning screws 21 from the first adjusting rod 17 and the second adjusting rod 19. The positioning sleeve 18 is slid on the first adjusting rod 17 to adjust the horizontal position of the scraper 20, and the second adjusting rod 19 is slid on the positioning sleeve 18 to adjust the vertical position of the scraper 20. After adjustment, the two positioning screws 21 are rotated in the opposite direction to fix the first adjusting rod 17 and the positioning sleeve 18, so that the position of the scraper 20 remains fixed.

[0031] See Figure 6 As shown, it also includes a first guide rod 23 installed on the base 1 by bolt connection. A push plate 24 for pushing ceramic is slidably arranged on the first guide rod 23. The baffle 2 has an opening on the side near the push plate 24 to facilitate pushing the clay down. Two first elastic elements 25 for pushing the push plate 24 to slide and reset are arranged around the first guide rod 23. A pull frame 22 is installed on the side of the support plate 9 by bolt connection. The pull frame 22 has an inclined bottom surface.

[0032] When the support plate 9 slides down along the guide cabinet 5, the support plate 9 drives the pull frame 22 to push the push plate 24, so that the push plate 24 slides along the first guide rod 23. At this time, the first elastic element 25 is compressed and deformed by force. After the scraper 20 scrapes off the clay stuck to the edge of the mold 4 and the rolling plate 13, the clay falls to the stroke of the push plate 24. When the support plate 9 drives the pull frame 22 to move upward, the first elastic element 25 loses the force and returns to its original state, thereby pushing the push plate 24 to slide and reset along the first guide rod 23, so that the push plate 24 pushes the clay down from the base 1 through the opening on the baffle 2 for cleaning.

[0033] See Figure 7 and Figure 8As shown, it also includes a guide frame 26 installed on one side of the baffle 2 by bolt connection. A scraper 27 for scraping the clay at the bottom of the rolling disc 13 is slidably provided on the guide frame 26. A J-shaped groove is provided on the guide frame 26 to facilitate the rotation of the scraper 27 on the guide frame 26. A rotating shaft 28 is rotatably provided on the scraper 27. Second guide rods 29 are fixedly connected to both sides of the guide frame 26 by welding. The rotating shaft 28 is slidably connected to the two second guide rods 29. The rotating shaft 28 slides up and down along the second guide rods 29. A second elastic element 30 for pushing the rotating shaft 28 to slide upward and reset is wound around the second guide rods 29. A protrusion 2701 is fixedly connected to the scraper 27 by welding. The protrusion 2701 cooperates with the support plate 9.

[0034] When the support plate 9 is at a high position, the third motor 11 is started to drive the rolling disc 13 to rotate, so that the rolling disc 13 contacts the scraper 27. The scraper 27 scrapes off the clay at the bottom of the rolling disc 13. When the guide frame 26 drives the rolling disc 13 to move downward, the rolling disc 13 pushes the scraper 27 to slide downward along the scraper 27, so that the scraper 27 drives the rotating shaft 28 to slide downward along the second guide rod 29 and compress the second elastic element 30. When the scraper 27 slides to the bottom of the guide frame 26, as the rolling disc 13 continues to push the scraper 27, the scraper 27 will rotate along the rotating shaft 28. When the support plate 9 drives the support plate 9 to move upward, the support plate 9 pushes the protrusion 2701 to make the scraper 27 rotate. As the support plate 9 continues to rise, the second elastic element 30 pushes the rotating shaft 28, so that the rotating shaft 28 drives the scraper 27 to slide upward along the guide frame 26 to reset.

[0035] See Figure 1 and Figure 8 As shown, a rubber sleeve 31 is fitted on the protrusion 2701, and a support rod 32 is fixedly connected to the base 1 and the guide cabinet 5 by welding. The support rod 32 is slidably connected to the support plate 9.

[0036] The rubber sleeve 31 is used to reduce the contact friction between the support plate 9 and the protrusion 2701, so as to prevent the protrusion 2701 from being worn and unable to contact the support plate 9; the support rod 32 is used to reduce the bending stress of the support plate 9 and the screw 8, increase the support force on the support plate 9, reduce the wear of the screw 8, and extend the service life of the screw 8.
