Description

Technical Field

[0001] This invention relates to the field of ceramic processing equipment technology, specifically to a multi-functional CNC roll forming production line for daily-use ceramics. Background Technology

[0002] Everyday ceramics encompass various forms such as bowls, plates, basins, and cups, each with multiple shapes and sizes. These ceramics, varying in shape and size, are typically processed using a rolling mill production line. In this process, cut clay strips are placed into plaster molds and then conveyed by a conveyor belt to the bottom of the rolling mill, where they are rolled into shape by a high-speed rotating roller. Different types of ceramics require different types of molds and rollers for processing. The amount of clay strips, the roller's angle, and the rotation speed all need to be adjusted accordingly. Traditional rolling mills have relatively fixed equipment settings, requiring manual adjustments after shutdown, and cannot be automatically adjusted during production. Therefore, they cannot meet the needs of continuous production of various types of small-batch everyday ceramic sets. A new type of device is needed to solve these problems. Summary of the Invention

The rear screw 70 is screwed into contact with the rocker plate 68. The cutting blade 71 is installed at the head of the rocker plate 68.

[0032] The working principle of this invention is as follows:

[0033] The feeding motor 40 is started, and the mud support plates 42 carrying mud rods are rotated one by one to the top. Then, the rodless cylinder 44 pushes the mud rods in the uppermost mud support plate 42 into the mud inlet of the combined cylinder 35 through the push plate. Under the conveying of the screw conveyor shaft 37, the mud material evacuated by the vacuum box 3501 is squeezed out from the mud outlet of the combined cylinder 35. The linear pusher 48 moves the positioning probe 49 to the corresponding position according to the mold type identified by the mold sensor. When the positioning probe 49 senses the head of the extruded mud strip, the reduction motor 36 stops the extrusion. The mud feeding cylinder 50 pushes out the vacuum suction cup 51 to pick up the mud strip. Then, the mud cutting cylinder 47 pushes down the blade to cut the mud strip. The steering cylinder 52 pushes the mud feeding cylinder 50 to the vertical position. The vacuum suction cup 51 pushes the mud strip into the mold 8 below under the push of the mud feeding cylinder 50.

[0034] The mold 8 carrying the clay strip continues to move forward with the circulation line. At the same time, the turntable 1 rotates the corresponding roller head 2 to the tool changing station. The push cylinder 3 pushes the moving plate 10 outward, moving the roller head 2 below the roller head seat 4. The lifting rail 20 drives the roller head seat 4 downward, causing the pull stud 201 to push into the clamping cylinder 27 and contact the top block 28. Then, the tool-cutting cylinder 5 drives the pull rod 24 upward, forcing the limit bead 2701 to limit the pull stud 201. After the roller head 2 is clamped, the roller head seat 4 and the moving plate 10 are reset one after the other. The adjusting motor 33 adjusts the included angle of the roller head seat 4 through the push-pull rod 30. When the mold 8 reaches the top surface of the mold support 17, the circulation line is paused. The electric lifting plate 14 is started to lift the mold 8 so that it corresponds to the roller head 2. The rotary mold motor 16 and the drive motor 22 are started to drive the mold 8 and the roller head 2 to rotate respectively, and the clay strip in the mold 8 is rolled and formed. The two linear modules are started to adjust the cutter 71 to a suitable position to cut off the excess clay generated during the rolling process. The air blowing pipe can be fixed on the carrier plate 62 to blow the excess clay into the waste conveyor belt 21 and take it out of the production line.

[0035] After the rolling operation is completed, all components are reset. The mold 8, carrying the formed blank, continues to advance into the drying chamber 7 for drying. The dried blank flows out from the outlet of the drying chamber 7. The vertical electric rail 57 drives the vertical suction cup 59 to descend, adsorb the blank, and then reset. Subsequently, the transfer motor 55 is started to move the transfer seat 56 above the conveyor belt 54. The vertical suction cup 59 descends again to release the blank, which then enters the next process with the conveyor belt 54. The circulating line in this invention is equipped with different types of molds 8. The feeding mechanism, tool changing platform, and adaptive roller head seat 4 distributed around the production line cooperate with each other. According to the type of mold 8, an appropriate amount of clay strips can be added, the roller head 2 can be changed, and parameters such as tilt angle and speed can be adjusted to achieve continuous production of different types of ceramics without stopping the machine. It is suitable for the production of various types and small batches of daily-use ceramics.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
