Description

Technical Field

[0001] The utility model belongs to the technical field of three-roller grinders, and more specifically relates to a slot positioning mechanism of a baffle device of a three-roller grinder. Background Art

[0002] The three-roll mill, also known as the three-roll mill, is a device suitable for grinding liquid slurries and pastes such as paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, etc. It achieves the grinding effect by squeezing the surfaces of three horizontal rollers against each other and rubbing them at different speeds. It is the most effective grinding and dispersing equipment for high-viscosity materials. When grinding pigments, the baffle device of the three-roll mill, if not effectively controlled by the baffle device, may cause the pigments to aggregate in certain areas, resulting in uneven grinding and suboptimal color and fineness. For example, when processing some hazardous chemicals, the baffle can effectively block possible splashing materials to ensure the personal safety of the operator.

[0003] The middle baffle plate device in the existing technology is mostly installed in a manually adjustable position and height. Its structure is simple and easy to install. However, it is found during use that in most cases the grinding material is added manually, which results in excessive grinding material. At this time, it is necessary to adjust the grinding width between the two baffle plates so that the material is evenly dispersed on the grinding roller. The baffle plate in the existing technology needs to be stopped for adjustment, otherwise safety hazards may occur. The adaptability of the baffle plate device needs to be improved, and the installation height of the baffle plate device in the existing technology is fixed, and the position adjustment between the grinding rollers is limited.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a slot positioning mechanism of a baffle plate device of a three-roll grinder is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a slot positioning mechanism for a baffle device of a three-roller grinding machine to solve the above problems.

[0006] The purpose and function of the slot positioning mechanism of the baffle plate device of the three-roller grinding machine of the utility model are achieved by the following specific technical means:

[0008] Furthermore, the mounting plate assembly includes two triangular mounting seats symmetrically installed in the middle of the top surface of the three-roll grinder, and the triangular mounting seats are threaded with fixing bolts, which are threadedly connected to the top surface of the three-roll grinder. A slide plate is fixedly installed between the two triangular mounting seats.

[0009] Furthermore, the driving mechanism includes a motor fixedly installed in the middle of the top surface of the slide plate, the rotating end of the motor passes through the middle of the inner cavity of the slide plate and is fixedly installed with a gear, a T-shaped slot is symmetrically opened in the inner cavity of the slide plate, two racks are slidably arranged in the T-shaped slot, the two racks are arranged in parallel and staggered, and the ends of the two racks close to each other are respectively engaged with the gears.

[0010] Furthermore, the material baffle assembly includes a C-shaped plate arranged on the bottom surface of the slide plate, and two T-shaped blocks are symmetrically installed on the top surface of the C-shaped plate. The T-shaped blocks are slidably arranged in the T-shaped groove of the slide plate, and one of the T-shaped blocks is fixedly connected to one end of the rack in the T-shaped groove on the same side.

[0011] Furthermore, the material baffle assembly also includes two material baffles that are slidingly symmetrically arranged at both ends of the C-shaped plate, a rectangular groove is opened in the middle of the material baffle, a round rod is fixedly installed in the middle of the rectangular groove, the end of the C-shaped plate is slidingly arranged in the rectangular groove, a spring is sleeved on the round rod, and the upper end of the spring is located on the bottom surface of the C-shaped plate.

[0012] Furthermore, two groups of foreign matter baffles are symmetrically fixedly installed on the slide plate.

[0013] Furthermore, the foreign matter baffle is preferably made of transparent plastic material.

[0014] Furthermore, scale lines are marked on the front and rear side walls of the chute plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The utility model drives the gear to rotate through a motor, and the rotation of the gear drives the racks meshing on the front and rear sides thereof to slide toward each other, so that the T-shaped blocks at the other ends of the two racks drive the C-shaped plates to slide toward each other in the T-shaped grooves, thereby driving the two baffle plates at both ends of the C-shaped plate and the two baffle plates of the C-shaped plate on the other side to approach each other, thereby realizing the adjustment of the grinding width before operation. Similarly, during the grinding process, the motor drive can realize fast and safe adjustment without stopping the operation.

[0017] 2. When the distance between the grinding rollers is adjusted, the baffle plate is clamped by the two grinding rollers and slides upward. The C-shaped plate and the bottom surface of the rectangular groove squeeze the spring in the middle of the round rod, so that the spring continuously releases elastic potential energy, thereby making the bottom surface of the baffle plate fit closely with the surface of the grinding roller, effectively ensuring the setting of the grinding width and realizing the self-adaptation of the baffle plate height without manual adjustment.
