Description

Technical Field

[0001] This invention relates to an automated production line equipment for ceramic blanks, specifically a centrifugal mechanism for the slip casting process in the production of ceramic daily necessities. Background Technology

[0002] The existing centrifugal mechanisms used in the slurry casting process for producing ceramic daily necessities are not highly modular, lack automation, and have complex structures. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide a centrifugal mechanism for the slurry injection process in the production of ceramic daily necessities, which has a high degree of modularity and automation.

[0004] The objective of this invention is achieved as follows.

[0005] A centrifugal mechanism for slip casting process in the production of ceramic daily necessities includes a clamp for clamping a clay mold, a support, and a drive device for rotating the clamp. At least two sets of clamps are arranged side by side in the support, and a drive device is provided below each set of clamps. When the clamps are not rotating, the support supports the clamps. When the clamps need to rotate, the drive device supports the clamps above them. The drive device first drives the clamps away from the support, and then drives the clamps to rotate after they leave the support.

[0006] The above technical solution can be further improved as follows.

[0007] The outer surface of the bracket is provided with a pivot and a moving mechanism.

[0008] The moving mechanism is a roller, bearing, or slider.

[0009] The fixture includes a tray for supporting the mold, columns standing around the tray, and clamping plates installed on the sides of the columns. A pull rod is provided on the column, which can move up and down relative to the column. A first spring is sleeved on the pull rod, which makes the pull rod always tend to move downward. A connecting rod structure is provided on the back of the clamping plate. The connecting rod structure is rotatably connected to the pull rod, the column, and the clamping plate. When the pull rod is pulled up, the connecting rod structure retracts, causing the clamping plate to move closer to the column. When the pull rod is released, the first spring causes the pull rod to move downward, and the downward movement of the pull rod forces the connecting rod structure to push the clamping plate away from the column.

[0010] The top of the column extends a support arm toward the center of the tray. A pressure rod is provided on the support arm. The pressure rod can move up and down relative to the support arm. A second spring is sleeved on the pressure rod, which makes the pressure rod always tend to move downward.

[0011] The linkage structure includes a first linkage and a second linkage. One end of the first linkage is rotatably connected to the pull rod, and one end of the second linkage is rotatably connected to the column. The other ends of the first linkage and the second linkage are rotatably connected to the back of the clamping plate.

[0012] The bracket has two or more clamp holes arranged side by side, and a support clamp is provided around the clamp holes. The tray is located inside the clamp holes, and the tray is supported by the support clamp. The tray also has a clearance notch around its perimeter. When the clamp is rotated by an angle, the clearance notch surrounds the support clamp, and the tray can leave the bracket from the clamp holes.

[0013] The tray is provided with a positioning hole, and the driving device is located below the tray. The support of the driving device is inserted upward into the positioning hole, causing the tray to rotate away from the support.

[0014] The columns standing around the pallet are provided with horizontal reinforcing ribs.

[0015] This invention features a simple and reasonable structural design, a highly modular and automated centrifugal mechanism, reduced production line costs, and significantly improved efficiency. The rapid up-and-down movement of the pull rod enhances the working efficiency of the clamps. The simple drive structure for moving the pull rod reduces the cost of automated production lines for ceramic daily necessities and lowers the failure rate. Mold clamping and releasing are also convenient. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] Example 1. Combined with... Figures 1 to 6 A centrifugal mechanism for slip casting in the production of ceramic daily necessities includes a clamp 100 for clamping a clay mold, a support 200, and a drive device 300 for rotating the clamp. The support 200 has a pivot 201 and rollers 202 on its outer surface. The support 200 has three clamp holes 203 arranged side-by-side. Each clamp hole contains a set of clamps. Below each of the three clamps 100 is a drive device 300. When the clamps are not rotating, the support 200 supports the clamps 100. When the clamps need to rotate, each drive device 300 supports the clamp 100 above it. The drive device first drives the clamp away from the support, and after the clamps leave the support, the drive device then drives the clamps to rotate. Since the drive device 300 is prior art, it will not be described in detail in this embodiment.

[0027] Combined Figures 7 to 9 The fixture is further described below. The fixture 100 includes a tray 1 for supporting the mold, two uprights 2 standing around the tray 1, a horizontal reinforcing rib 3 between the two uprights 2, and a clamping plate 4 on the inner side of each upright 2. The tray is provided with positioning holes 101.

[0028] The column 2 is provided with a pull rod 5, which can move up and down relative to the column 2. A first spring 6 is sleeved on the pull rod 5, which makes the pull rod 5 always have a downward tendency. The back of the clamping plate 4 is provided with a connecting rod structure.

[0029] The linkage structure includes a first link 7 and a second link 8. One end of the first link 7 is rotatably connected to the pull rod 5, and one end of the second link 8 is rotatably connected to the column 2. The other ends of the first link 7 and the second link 8 are rotatably connected to the back of the clamping plate 4.

[0030] Pulling the lever upwards causes the connecting rod structure to retract, bringing the clamping plate closer to the column. Releasing the lever releases the first spring, which causes the lever to move downwards. This downward movement forces the connecting rod structure to push the clamping plate away from the column, thus clamping the mold.

[0031] The top of the column 2 extends a support arm 9 toward the center of the tray. A pressure rod 10 is provided on the support arm 9. The pressure rod 10 can move up and down relative to the support arm 9. A second spring 11 is sleeved on the pressure rod 10. The second spring 11 makes the pressure rod 10 always have a downward tendency.

[0032] If the clay mold has a top cover, the mold needs to be pressed down in the height direction. Since the pressure rod always has a downward tendency, the height between the bottom of the pressure rod and the tray is less than the height of the mold in the natural state. When the pressure rod is pulled up and the mold is placed in, as long as the pressure rod is released, the bottom of the pressure rod will definitely press on the top surface of the mold.

[0033] Combined with appendix Figure 6 The bracket 200 has three clamping holes 203 arranged side by side. Each clamping hole 203 has a supporting clamping opening 204 around its periphery. The tray 1 is located within the clamping hole 203, and its periphery is supported by the supporting clamping opening 204. The tray 1 also has a clearance notch 102 around its periphery. When the clamp 100 needs to rotate, the drive device 300 operates. The support member 301 of the drive mechanism 300 inserts upward into the positioning hole 101, causing the tray 1 to rotate and leave the bracket 200. After the drive device 300 drives the clamp to rotate at an angle, the clearance notch 102 surrounds the supporting clamping opening 204, allowing the tray 1 to leave the bracket 200 from the clamping hole 203. After the clamp leaves the bracket, the drive device drives the clamp to rotate.
