Description

Technical Field

[0001] This utility model belongs to the field of ceramic rolling technology, and in particular relates to a new type of rolling machine for ceramic production. Background Technology

[0002] Ceramic rolling is a process that uses the rolling and pressing force of rollers to evenly distribute ceramic clay within a mold and gradually form the desired shape. In the process, it is necessary to first prepare an appropriate amount of ceramic clay and a mold, place the clay in the mold, and then adjust the rolling speed and pressure of the rollers to press the clay evenly. Finally, through demolding, trimming and other steps, the ceramic shape is completed.

[0003] When rolling different types of ceramic molds, ceramic rolling machines require the use of rolling heads of the same type. However, existing ceramic rolling machines do not allow for easy disassembly and replacement of the rolling heads, which affects the efficiency of rolling different types of ceramics. Utility Model Content

[0004] This utility model addresses the problem that existing ceramic rolling mills make it inconvenient to disassemble and replace the rolling head, and proposes the following technical solution:

[0005] A novel rolling mill for ceramic production includes: a worktable and a movable frame. A first motor is fixedly installed inside the worktable, and a mold base is fixedly connected to the output end of the first motor. A second motor is fixedly installed inside the movable frame. The output shaft of the second motor is connected to a rotating shaft that is rotatably connected to the movable frame via a belt connection structure. A rolling head is provided at the bottom end of the rotating shaft.

[0006] The rotating shaft has symmetrically slidingly mounted locking blocks inside. The rolling head has a locking groove at the position corresponding to the outer side of the locking blocks. The rotating shaft has a fixedly connected positioning post inside. The outer surface of the positioning post has a fixedly connected reset spring. The top of the locking block has a fixedly connected push plate.

[0007] As a preferred embodiment of the above technical solution, the number of reset springs is set to two, and the ends of the two reset springs away from the positioning post are fixedly connected to the locking block.

[0008] As a preferred embodiment of the above technical solution, both of the card blocks are set to a trapezoidal shape.

[0009] As a preferred embodiment of the above technical solution, the surfaces of the two card blocks are symmetrically provided with sliding grooves, and limit blocks are fixedly installed inside the rotating shaft at the corresponding positions of the sliding grooves.

[0010] As a preferred embodiment of the above technical solution, an inner ring is fixedly installed on the top of the workbench, and two outer rings are sleeved on the outer surface of the inner ring. The two outer rings are both semi-circular in shape, and the interior of each of the two outer rings is connected to a screw by a thread.

[0011] As a preferred embodiment of the above technical solution, the outer ring is movably connected with a ball bearing, and a raceway is provided at the bottom of the mold base corresponding to the highest point of the ball bearing from the ground.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model uses a set of locking blocks and springs to install the rolling head by inserting the locking blocks into the slots inside the rolling head. When it needs to be replaced, press the two push plates at the same time to make the locking blocks move towards the center of the rolling head, so that the two locking blocks disengage from the slots inside the rolling head at the same time, thereby disassembling and replacing the rolling head. The operation is simple and easy to install.

[0014] (2) By setting an outer ring, the outer surface of the ball fits into the inside of the raceway at the bottom of the mold base. When the No. 1 motor drives the mold base to rotate, the ball and raceway work together to effectively improve the stability of the mold base during rotation, prevent the mold base from shaking during rotation, and prevent the surface of the ceramic clay rolled by the rolling head from being defective or uneven.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a novel rolling mill for ceramic production, such as... Figures 1 to 5 As shown, it includes a workbench 1 and a movable frame 2. A first motor 3 is fixedly installed inside the workbench 1. A mold base 4 is fixedly connected to the output end of the first motor 3. A second motor 5 is fixedly installed inside the movable frame 2. The output shaft of the second motor 5 is connected to a rotating shaft 6 that is rotatably connected to the movable frame 2 via a belt connection structure. When the second motor 5 works, it drives the motor belt to rotate, which in turn drives the rotating shaft 6 to rotate. A rolling head 7 is provided at the bottom end of the rotating shaft 6.

[0024] The rotating shaft 6 has two symmetrically sliding locking blocks 8 inside. Both locking blocks 8 are trapezoidal in shape. The rolling head 7 has a slot 9 inside corresponding to the outer position of the locking blocks 8. The design of the locking blocks 8 makes the contact surface between the locking blocks 8 and the rolling head 7 more stable and reduces the risk of the locking blocks 8 shaking. The rotating shaft 6 has a fixedly connected positioning post 10 inside. The outer surface of the positioning post 10 is fixedly connected to a return spring 11. There are two return springs 11 in total. The ends of the two return springs 11 away from the positioning post 10 are fixedly connected to the locking blocks 8. The top of the locking blocks 8 is fixedly connected to a push plate 14. By inserting the locking blocks 8 into the rolling head 7, the two return springs 11 are deformed. When the locking blocks 8 are fully engaged in the slot 9 inside the rolling head 7, the return springs 11 are no longer compressed and return to their original state, so that the locking blocks 8 are fixedly installed at the bottom end of the rotating shaft 6.

[0025] like Figure 2 and Figure 3 As shown, the surfaces of the two card blocks 8 are symmetrically provided with sliding grooves 12. The inside of the rotating shaft 6 is fixedly installed with limit blocks 13 at the corresponding positions of the sliding grooves 12. With the help of the sliding grooves 12 and the limit blocks 13, the card blocks 8 slide along the path direction of the sliding grooves 12 when they move, thereby improving the accuracy of the movement of the card blocks 8.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, an inner ring 15 is fixedly installed on the top of the workbench 1. Two outer rings 16 are fitted onto the outer surface of the inner ring 15. The two outer rings 16 are semi-circular in shape, and the inner diameter of the circle formed by the two outer rings 16 is equal to the outer diameter of the inner ring 15. The top of the outer rings 16 is attached to the bottom of the mold base 4. The interior of each of the two outer rings 16 is connected to a screw 17 by a thread. By rotating the screw 17, the two outer rings 16 are tightly fitted onto the outer surface of the inner ring 15. A ball bearing 18 is movably connected inside the outer rings 16. A raceway 19 is provided at the bottom of the mold base 4 corresponding to the highest point of the ball bearing 18 from the ground. This allows the outer surface of the ball bearing 18 to fit into the raceway 19 at the bottom of the mold base 4, effectively improving the stability of the mold base 4 during rotation and preventing shaking during rotation, thereby avoiding defects in the ceramic clay rolled by the rolling head 7.

[0027] Working principle: When the rolling head 7 of the device needs to be installed, the rolling head 7 is operated to insert the locking block 8 into the interior of the rolling head 7. During the insertion process, the return spring 11 is compressed and deformed. When the locking block 8 is fully inserted into the slot 9, the locking block 8 is no longer compressed. The return spring 11 returns to its original state due to the deformation, so that the outer surface of the locking block 8 is tightly attached to the inner wall of the rolling head 7, so that the rolling head 7 is fixedly installed at the bottom end of the rotating shaft 6.

[0028] When it is necessary to disassemble the rolling head 7, press the push plate 14 at the same time to make it move the two locking blocks 8 towards the center of the rolling head 7, so that the locking blocks 8 are completely disengaged from the locking groove 9 and are no longer limited, thereby removing the rolling head 7. The operation process is simple and convenient for disassembling and replacing different models of rolling heads 7. By fixing the two semi-circular outer rings 16 to the outer surface of the inner ring 15, and with the action of the ball bearings 18 and the raceway 19, when the No. 1 motor 3 drives the mold base 4 to rotate, the stability of the mold base 4 during rotation is effectively improved.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
