[0031] As for the mold shifting assembly 5, the mold shifting assembly 5 includes a retracting base 52 and a clamping arm 53 mounted on the retracting base 52. The clamping arm 53 is arranged on both sides of the mold shifting assembly 5 for clamping both sides of the mold A. The clamping arm 53 is connected to an opening and closing assembly 55 for controlling the opening and closing of the clamping arm 53. The opening and closing assembly 55 includes an opening and closing cylinder 553 and a sliding seat 551 mounted on the push arm of the opening and closing cylinder 553. Both sides of the sliding seat 551 are hingedly connected to the end of the clamping arm 53. The forward position of the end of the clamping arm 53 is hingedly connected to the retracting base 52, so that the movement of the sliding seat 551 drives the connecting rod 552 to pull the end of the clamping arm 53, so that the clamping arm 53 is expanded or retracted;

[0032] At the same time, the mold shifting assembly 5 also includes a transposition base 51 movably mounted on the front moving platform 4, the transposition base 51 moves between the die-in conveyor belt 1, the rolling station 3 and the die-out conveyor belt 6, the retracting base 52 is movably mounted on the transposition base 51 and the moving direction is perpendicular to the transposition base 51, the front moving platform 4 is provided with a known moving driving structure such as a transmission belt, a pulley and a motor, which is used to drive the transposition base 51 to move, and a retracting cylinder 56 is provided between the retracting base 52 and the transposition base 51, which is used to drive the retracting base 52 to approach or move away from the rolling station 3;

[0033] For the rolling equipment, a groove-shaped mold base is usually provided in front of the rolling equipment, and the mold A is placed in the groove of the mold base. The mold base is driven by a motor to rotate and then the mold A is driven to rotate. The rolling head 32 of the rolling equipment rolls the mud in the mold A. After rolling forming, a lifting structure is provided inside the mold base to lift the mold A for transportation. However, in this embodiment, the rolling equipment is provided with a turntable 31 to drive the mold A to rotate. The top of the turntable 31 is flat and the mold A is placed on the top surface of the turntable 31. The plane at the top of the turntable 31 is parallel to the direction in which the mold A moves between the rolling station 3 and the ejection conveyor belt 6. It is also necessary to set the horizontal height of the plane at the top of the turntable 31 to be lower than or equal to the ejection conveyor belt 1 and higher than the ejection conveyor belt 6. The plane at the top of the turntable 31 is provided with a structure or material for increasing the friction with the bottom surface of the mold A, such as a micro-spike protrusion structure and a rubber material, so that it directly contacts the mold A in the form of a plane, thereby reducing the situation in which the ejection failure of the mold A in the rolling step causes the jamming.

[0034] In coordination with this, in this embodiment, the clamp arm 53 is used to apply a downward force to the mold A so that the bottom surface of the mold A is close to the turntable 31, and a plurality of side wheels 54 are provided on the clamp arm 53 to abut against the mold A so that the mold A rotates with the turntable 31 under the clamping of the clamp arm 53. Two side wheels 54 are provided on a single clamp arm 53, and the side wheels 54 on the clamp arms 53 on both sides form four clamping points to clamp the two sides of the mold A. For this purpose, an adjustment component is provided on the clamp arm 53, and the adjustment component drives the side wheels 54 to move downward. Then, the side wheels 54 are used to apply downward force to the mold A. In the basic setting, the side wheels 54 can be moved downward by adjusting the assembly to rotate the clamping arm 53 to apply downward force to the mold A. However, in this embodiment, the side wheels 54 are rotated by using a horizontal line tangent to the side surface of the mold A as a rotation axis 531 to ensure that the contact between the side wheels 54 and the mold A is stable on a vertical straight line, so that the force applied by the side wheels 54 to the mold A and the rotation state of the mold A under the clamping of the side wheels 54 are more stable;

[0035] For this purpose, the part of the side wheel 54 that contacts the mold A is made of rubber material, so that when the side wheel 54 swings downward, there is space for it to be squeezed and deformed by the mold A, and it can have greater friction when in contact with the side of the mold A;

[0036] To this end, the adjustment component includes a rotating shaft 531 and a guide frame 532. Both ends of the rotating shaft 531 are obliquely installed on the clamping arm 53 through the guide frame 532. The side wheels 54 are installed on the rotating shaft 531. The rotating shaft 531 rotates to drive the side wheels 54 to swing downward around the axis of the rotating shaft 531, exerting a downward force on the mold A. The horizontal plane where the axis of the rotating shaft 531 is located is defined as a comparison horizontal plane. In the cross section of the mold A on the comparison horizontal plane, an extension line of a radius is perpendicular to the axis of the rotating shaft 531. The side wheels 54 are located on the extension line of the radius between the axis of the rotating shaft 531 and the center of the cross section of the mold A. That is, on the comparison horizontal plane, it can be seen that the rotating shaft 531 can be tangent to the side of the mold A.

[0037] In order to drive the rotating shaft 531 to rotate, the adjustment assembly also includes an adjustment seat 533 movably mounted in the clamping arm 53. The rotating shaft 531 is provided with a guide arm 531a. The middle part of the adjustment seat 533 is provided with a slot along the length direction of the adjustment seat 533. The rotating shaft 531 and the adjustment arm move in the slot. The adjustment seat 533 is connected to an adjustment cylinder 534. The adjustment cylinder 534 drives the adjustment seat 533 to move in the clamping arm 53 along the length direction of the clamping arm 53, so that the adjustment seat 533 drives the rotating shaft 531 to switch the state. In the state, driven by the adjustment seat 533 driven by the adjustment cylinder 534, the state of the rotating shaft 531 in the adjustment seat 533 includes a static state and a rotating state. The groove is provided with a flat surface 533a that abuts against the guide arm 531a and is used to stabilize the rotating shaft 531 in a static state. The groove is provided with a convex guide protrusion 533b that is used to press the guide arm 531a to rotate the rotating shaft 531. The guide protrusion 533b is gradually convex starting from the front edge that contacts the guide arm 531a.

[0038] It should be noted that the obtuse angle formed by the rotating shaft 531 and the clamping arm 53 on the side close to the mold A is defined as the clamping reference angle, the angles between the rotating shaft 531 and the clamping arm 53 at the four clamping points are equal, and the two rotating shafts 531 on the same clamping arm 53 are symmetrically arranged with a symmetry axis perpendicular to the clamping arm 53; the guide arms 531a on the rotating shaft 531 on the same clamping arm 53 are in the same direction and parallel to the clamping arm 53, and the angle formed by the guide arm 531a and the rotating shaft 531 on the side close to the mold A is defined as the guide arm 531a. The reference angle includes an obtuse angle and an acute angle; the slot of the adjustment seat 533 is provided with a guide protrusion 533b above the guide arm 531a that forms the obtuse guide reference angle, and a flat surface 533a below; the slot of the adjustment seat 533 is provided with a flat surface 533a above the guide arm 531a that forms the acute guide reference angle, and a guide protrusion 533b below; in this embodiment, the reference angle is set to 135°, so the intersection of the four side wheels 54 forms a square, which is convenient for setting and adjustment;

[0039] Moreover, in the present embodiment, the groove of the adjustment seat 533 is provided with a recessed clearance groove 533c on the opposite side of the guide protrusion 533b and adjacent to the flat surface 533a, which is used to make way for the swinging guide arm 531a; the projection on the horizontal plane of the front edge of the guide protrusion 533b that is in contact with the guide arm 531a is adjacent to the edge of the clearance groove 533c into which the guide arm 531a leaves the flat surface 533a, so that the rotating shaft 531 will only start to rotate driven by the guide protrusion 533b after it is about to enter the clearance groove 533c, thereby avoiding interference.

[0040] In the specific implementation, two groups of mold shifting components 5 are provided on the front moving platform 4 and are respectively used to move the mold A between the mold feeding conveyor belt 1 and the rolling station 3, and between the rolling station 3 and the mold discharging conveyor belt 6. The mold feeding conveyor belt 1 conveys the two molds A to the front of the front moving platform 4, and the mold shifting components 5 near the mud throwing station 2 work. The opening and closing cylinder 553 drives the sliding seat 551 to move, and the sliding seat 551 moves to drive the connecting rod 552 to pull the end of the clamping arm 53, so that the clamping arm 53 is unfolded, allowing the mold A to enter the clamping arm 53. The extruder 22 is within the range and is located below the mud throwing station 2. The shifting cylinder 24 drives the shifting frame 23 to rotate so that the suction cup arm 27 points to the extruder 22. The splitting cylinder 28 drives the suction cup arm 27 to close the two extrusion ports of the extruder 22 to the middle. The extruder 22 extrude the mud. After the suction cup arm 27 sucks the mud, a cutter is provided outside the extruder 22 to cut the mud. The shifting cylinder 24 drives the shifting frame 23 to rotate so that the suction cup arm 27 turns downward. The splitting cylinder 28 drives the suction cup arm 27 to separate to both sides close to the mold A, and releases the adsorption, so that the mud falls into the mold A.

[0041] After the mud throwing is completed, the mold shifting assembly 5 near the mud throwing station 2 works, and the opening and closing cylinder 553 drives the sliding seat 551 to move, and the sliding seat 551 moves to drive the connecting rod 552 to open to both sides, so that the clamping arm 53 is retracted to clamp the mold A, and then the moving driving structure of the front moving platform 4 drives the mold shifting assembly 5 near the mud throwing station 2 to move to the rolling station 3, and then the clamping arm 53 is unfolded, and the mold A is placed on the flat turntable 31, and the closing cylinder 56 drives the closing base 52 to move outward away from the rolling station 3, and then the mold shifting assembly 5 near the mud throwing station 2 returns from the rolling station 3 to the mud throwing station 2, and the mold shifting assembly 5 near the rolling station 3 comes to the rolling station 3, and the closing cylinder 56 drives the closing base 52 to move inward, allowing the clamping arm 53 to enter the two sides of the mold A, and the opening and closing cylinder 553 drives the clamping arm 53 to clamp the mold A, and the four side wheels 54 on the two clamping arms 53 form The four clamping points clamp the mold A, and then the rolling head 32 enters the mold A for rolling. The turntable 31 rotates synchronously. The rotation direction of the rolling head 32 is opposite to the rotation direction of the turntable 31 and the mold A driven by the turntable 31, so that the mud material is kneaded and rolled in the inner wall of the mold A. When the turntable 31 drives the mold A to rotate, the adjusting cylinder 534 gradually extends to drive the adjusting seat 533 to move on the clamping arm 53, and the guide protrusion 533b on the adjusting seat 533 presses the guide arm 531a to rotate the rotating shaft 531, thereby driving the side wheel 54 to gradually swing downward, gradually applying a downward force to the mold A, so that the mold A can be tightly attached to the turntable 31 for rotation. It should be noted that when the rolling head 32 just enters the mold A, due to the mud material at the bottom, the initial rolling stage also applies downward pressure to the mold A, and cooperates with the side wheel 54 to better allow the turntable 31 to drive the mold A to rotate;

[0042] After rolling is completed, the moving drive structure of the front moving platform 4 drives the mold shifting assembly 5 near the rolling station 3 to move to the demolding conveyor belt 6, and the unloading station 7 is provided with a suction cup arm 27 to suck the formed mud out of the mold A and transfer it to other required processing steps. Then the closing cylinder 56 drives the closing base 52 to move outward away from the demolding conveyor belt 6 and return to the front of the rolling station 3, waiting for the mold shifting assembly 5 near the mud throwing station 2 to leave the rolling station 3 and then take over the mold A of the rolling station 3, thereby completing the processing cycle.

[0043] Moreover, in the present embodiment, since the moving direction of the adjustment seat 533 is different from the rotation direction of the rotating shaft 531, in order to allow the guide protrusion 533b to better contact the guide arm 531a, the end of the guide arm 531a is inclined and the inclined surface is parallel to the axis of the rotating shaft 531, the front end edge of the guide protrusion 533b is parallel to the end of the guide arm 531a, and the adjacent part of the flat surface 533a and the give way groove 533c is parallel to the axis of the rotating shaft 531, so that the guide protrusion 533b can better drive the guide arm 531a.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
