Description

Screen plate clamping device of rasping machine

Technical Field

The utility model relates to the technical field of cassava batch processing equipment, in particular to a screen plate clamping device of a file grinder.

Background

The rasping machine is a common potato processing device, potato starch is mainly stored in the meat part of tuberous root, raw material particles are relatively large, internal tissues are not easy to damage, and the tissue structure of the potato block is fully damaged by repeated rasping, so that tiny starch particles can be smoothly released from the tuberous root, and the starch extraction rate is improved. The material enters the shell of the rasper through the inlet at the upper part and is broken by the impact, shearing and grinding actions of the saw blade moving at high speed, the lower part of the rotor is provided with a sieve plate, the material smaller than the sieve pore size in the broken material is discharged through the sieve plate, and the particles larger than the sieve pore size are blocked on the sieve plate and continuously hit and grind by the saw blade, and finally are discharged out of the rasper through the sieve plate.

In the in-service use, the sieve generally needs a week to inspect in proper order, observes whether the sieve mesh has the condition of harm and jam, in time overhauls, and the draw-in groove of the general embedding both sides blade holder of sieve among the prior art is fixed, uses after a certain time, because the inside siltation starch of draw-in groove, leads to the dismouting maintenance of sieve very inconvenient, is difficult to demolish and install, and the in-process sieve is damaged the deformation easily, can't resume the use.

Disclosure of Invention

The utility model aims to provide a clamping device for a screen plate of a rasper, one end of the clamping device can be adjusted in tightness, so that an internal screen plate can be conveniently extracted for regular maintenance, and the problem of deformation and damage of the screen plate caused by repeated disassembly in the prior art is avoided.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a rasper sieve chucking device, includes the rasper casing, the rasper casing inside have the rotor through driving motor output shaft, the inside packing of recess of rotor have the rasping strip, the rotor below be equipped with the sieve, sieve one side embed into the rasper blade holder recess inside, sieve opposite side below be equipped with L type layer board, L type layer board lower surface be connected with from preceding a plurality of flexible piston rods to the back, flexible piston rod communicate to the cylinder inside, L type layer board horizontal segment bearing sieve opposite side lower surface, the vertical section upper end of L type layer board spacing through the baffle.

Further, the cylinder is fixed on the surface of the rasping machine shell, and the cylinder is externally connected with a control panel.

Further, the baffle plate is welded and fixed on the side surface of the shell of the rasping machine.

Further, when the L-shaped supporting plate rises to the highest point, the lower surface of the baffle plate is tightly propped, and when the L-shaped supporting plate descends to the lowest point, the L-shaped supporting plate is 5-7 cm away from the lower surface of the other side of the sieve plate.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the cylinder and the telescopic piston rod are arranged on the other side of the sieve plate, and the L-shaped supporting plate structure is matched, so that the tightness adjustment on the other side of the sieve plate is realized, the inner sieve plate is conveniently extracted, the regular maintenance is performed, and the problem of deformation and damage of the sieve plate caused by repeated disassembly in the prior art is avoided.

FIG. 2 is a schematic view of the L-shaped pallet of the present utility model after lowering;

in the figure: 1. a rasper housing; 2. a rotor; 3. filing a grinding strip; 4. a sieve plate; 5. a tool apron; 6. a baffle; 7. an L-shaped supporting plate; 8. and (3) a cylinder.

Detailed Description

The utility model is further described with reference to the following detailed drawings in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.

As shown in fig. 1, in the prior art, the fixing mode of the screen plate 4 inside the rasping machine shell 1 is that one side of the screen plate 4 is embedded into a groove of the tool apron 5, the other side is the same, the upper side is the rotor 2 with the rasping strip 3, the fixing structure of the other side of the screen plate 4 is redesigned in the application, specifically, the structure of the L-shaped supporting plate 7 is set, the lower side of the L-shaped supporting plate 7 drives the L-shaped supporting plate 7 to ascend and descend through a plurality of telescopic piston rods, the moving power source of the telescopic piston rods is an air cylinder 8, the upper side of the L-shaped supporting plate 7 is limited through the baffle 6, when the L-shaped supporting plate 7 ascends to the highest point, the L-shaped supporting plate 7 just supports the screen plate 4 to the horizontal position, and the vertical section of the L-shaped supporting plate 7 abuts against the lower surface of the baffle 6.
