[0002] A pair-roller roll press (also known as a double-roller roll press or a pair-roller crusher) is a commonly used ceramic granulation (also known as ceramic powder making) equipment in ceramic enterprises. Among them, a pair-roller roll press specifically designed for the specific process requirements of ceramic granulation is also called a pair-roller ceramic granulator.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN220972741U provides a pair-roller type ceramic granulator with adjustable roller spacing, which includes a machine box and two mutually rotatable extrusion rollers arranged in parallel in the machine box. Both ends of the roller shafts of the two extrusion rollers are respectively connected to two groups of bearing assemblies symmetrically arranged on the left side plate and the right side plate of the machine box. One end of the roller shafts of the two extrusion rollers respectively extends outside the side plates of the machine box and is connected to their respective drive motors. Among the two groups of bearing assemblies, at least one group of bearing assemblies is installed on the left side plate and the right side plate of the machine box in a manner that can move back and forth. By moving this bearing assembly back and forth, the roller spacing between the two extrusion rollers can be adjusted. The utility model can conveniently adjust the roller spacing of the granulator, enabling ceramic enterprises to use granulators of the same specification to produce ceramic powders with different particle sizes. In particular, when ceramic raw materials cannot fall through the roll gap, by adjusting the roller spacing, the non-falling ceramic raw materials can be conveniently cleaned.

[0004] The above-mentioned authorized patent has the following problems during use:

[0005] Although the above-mentioned authorized patent can complete the adjustment of the distance between the two extrusion rollers, it requires two hydraulic cylinders to drive and also requires a control device for controlling the two hydraulic cylinders, resulting in a high manufacturing cost of the entire device and being not conducive to popularization and use.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original pair-roller type ceramic granulator. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a pair-roller type ceramic granulator with adjustable roller spacing, including a machine case 1. Through grooves 2 are opened on both the front and rear sides of the machine case 1. A movable plate 3 is slidably installed inside the through groove 2. A movable extrusion roller 4 is rotatably installed between the movable plates 3 through bearings. The end of the movable extrusion roller 4 is fixedly connected to the output end of a first servo motor 5. The outer wall of the first servo motor 5 is fixedly mounted on the outside of the movable plate 3 through a mounting plate. A threaded hole 6 is opened in the middle of one side of the movable plate 3. A first rotating shaft 7 is installed inside the threaded hole 6. The end of the first rotating shaft 7 penetrates through the side wall of the machine case 1 and is fixed with a first bevel gear 8. The machine case 1 and the first rotating shaft 7 are rotatably connected through bearings. Fixing plates 9 are fixedly mounted on both the front and rear sides of the outer wall of the machine case 1. A second rotating shaft 10 is rotatably installed between the fixing plates 9 through bearings. A second bevel gear 11 is fixed on the outer wall of the second rotating shaft 10. The second bevel gear 11 is meshed with the first bevel gear 8. A crank 12 is fixedly mounted on the outside of the end of the second rotating shaft 10. There are two first rotating shafts 7, and the first rotating shafts 7 are in threaded connection with the threaded hole 6. A fixed extrusion roller 16 is rotatably installed inside the machine case 1 near the movable extrusion roller 4 through bearings. The end of the fixed extrusion roller 16 is fixedly connected to the output end of a second servo motor 17. The outer wall of the second servo motor 17 is fixedly mounted on the outer wall of the machine case 1 through a mounting plate. By rotating the crank 12 forward or backward, the movable extrusion roller 4 can be moved left or right, so as to conveniently adjust the distance between the movable extrusion roller 4 and the fixed extrusion roller 16. It is not necessary to use two hydraulic cylinders for driving, reducing the manufacturing cost of the pair-roller type ceramic granulator and being beneficial to the popularization and use of the pair-roller type ceramic granulator.

[0024] An anti-slip sleeve 15 is nested and fixed on the outside of the crank 12 to increase the friction force, which is beneficial to rotating the crank 12 through the anti-slip sleeve 15.

[0025] A groove 14 is opened on the inner side of the through groove 2. A baffle 13 is slidably installed inside the groove 14. The end of the baffle 13 is fixedly connected to the outer wall of the movable plate 3. The baffle 13 has two advantages. One is to prevent the raw materials inside the machine case 1 from leaking to the outside of the machine case 1, and the other is to play a role in limiting the movement of the movable plate 3.

[0026] The bottom of the through groove 2 near the inner side of the machine case 1 is designed to be inclined downward to prevent raw materials from accumulating at the bottom of the through groove 2.

[0027] Working principle: When using the double-roller ceramic granulator with adjustable roller spacing, first rotate the second rotating shaft 10 through the anti-slip sleeve 15 and the crank 12. The second rotating shaft 10 drives the two second bevel gears 11 to rotate simultaneously. The two second bevel gears 11 drive the two first rotating shafts 7 to rotate simultaneously through the two first bevel gears 8. Since the first rotating shafts 7 are threadedly connected to the threaded holes 6, the two first rotating shafts 7 drive the two movable plates 3 to move to the left simultaneously. The two movable plates 3 drive the two baffles 13 to move to the left inside the two grooves 14 at the same time. Thus, the two movable plates 3 drive the movable extrusion roller 4 and the first servo motor 5 to move to the left simultaneously, and then the distance between the movable extrusion roller 4 and the fixed extrusion roller 16 can be reduced. Similarly, by rotating the crank 12 in the reverse direction, the movable extrusion roller 4 can be moved to the right, and the distance between the movable extrusion roller 4 and the fixed extrusion roller 16 can be increased. By starting the second servo motor 17 to rotate forward, the second servo motor 17 can drive the fixed extrusion roller 16 to rotate forward. By starting the first servo motor 5 to rotate in reverse, the first servo motor 5 can drive the movable extrusion roller 4 to rotate in reverse, so that the raw materials can be rolled between the movable extrusion roller 4 and the fixed extrusion roller 16.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
