Description

Crusher blade gap pre-adjusting device

Technical Field

The utility model relates to a technical field is made to the breaker frock, concretely relates to breaker blade clearance pre-adjusting device.

Background

In the prior art, a production line film enters a traction section after being transversely stretched to be subjected to edge cutting and surface corona treatment, a cut thick edge is crushed by an online crusher and then conveyed to a raw material section for recycling, after the production line film is used for a period of time, the cutting edge of a blade becomes dull, the blade needs to be detached and replaced again for standby, after the installation is finished, the gap between a fixed blade and a rotary blade needs to be adjusted, the number of the blades is large (generally 20 rotary blades), if the gap is adjusted on site at each time, the time consumption is long, and the opening rate is greatly influenced.

The information disclosed in this background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a breaker blade clearance pre-adjustment device can carry out the pre-adjustment in advance to pairing rotation blade spare part, need not to adjust the clearance after waiting to change, reduces down time, promotes the rate of opening.

In order to achieve the above object, according to the utility model provides a breaker blade clearance is adjusting device in advance, including the adjustment body, be constructed flutedly on the adjustment body, the recess is used for placing rotating blade subassembly, interval between the groove founds the wall of the opposite side of recess equals the distance between the top of the rotating blade subassembly tail end of breaker and stationary knife, rotating blade subassembly has rotating blade and the adjusting screw of being connected with it, the adjusting screw can stretch out and draw back, in order to guarantee rotating blade subassembly with clearance between the wall is found in a side groove of recess reaches the default.

Preferably, said preset value is determined by feeler measurement.

Preferably, the preset value is 0.3 mm.

Preferably, the crusher blade gap pre-adjusting device further comprises a set screw, and the set screw is in threaded connection with the adjusting body.

Has the advantages that:

the length of the rotating blade assembly is preset and determined outside the rotor through the crusher blade gap preset adjusting device, and when the corresponding preset value gap is determined, the rotating blade assembly is directly connected onto the rotor through the pressing plate and the corresponding screw, so that the rotor of the crusher is not required to be adjusted, the downtime is greatly reduced, and the starting rate is improved.

Detailed Description

The technical scheme of the utility model is described in detail with the accompanying drawings.

In the prior art, as shown in fig. 1 and 2, an edge material slab enters a crusher from a feed inlet above a crusher body 10, a rotating blade 30 rotates at a high speed to cut an edge material with a fixed blade 40, the edge material is crushed into a certain small size, and the small size is leaked from a screen 60 to enter a discharge outlet, and the small size is conveyed to a raw material section by a fan for recycling. The crusher also comprises a rotor 20 as the main component, the rotary blade 30 is mounted on the rotor 20, the press plate 50 and the corresponding screw fix the rotary blade 30, the fixed blade 40 can be directly replaced without grinding, and the size is fixed. As shown in the enlarged partial view of fig. 2, the rotating knife assembly comprises a rotating knife blade 30 and an adjusting screw 31, the top gap between the rotating knife blade and the fixed knife 40 is 0.3mm, at present, in order to ensure the above gap, an operator needs to repeatedly adjust the position of the rotor 20, which is very troublesome and time-consuming, and the start-up rate of the device is very low, therefore, according to the present invention, the crusher knife blade gap pre-adjusting device is provided, which comprises an adjusting body 1, see fig. 3 and 4, wherein a groove 11 is formed on the adjusting body 1, the groove 11 is used for placing the rotating knife blade assembly, the distance between the groove vertical walls at the opposite sides of the groove 11 is equal to the distance between the tail end of the rotating knife blade assembly of the crusher and the top end of the fixed knife 40, the rotating blade assembly is provided with the rotating knife blade 2 and the adjusting screw 3 connected thereto, the adjusting screw 3 can extend and retract, so as to ensure that the clearance between the rotating blade assembly and the vertical wall of one side groove of the groove 11 reaches a preset value. In the specific operation, the preset value is determined by measuring the feeler 4, and other measuring methods can be adopted, wherein the preset value is 0.3 mm. In the technical scheme, the length of the rotating blade assembly is adjusted and determined outside the rotor 20 in advance through the crusher blade gap pre-adjusting device, and when the corresponding preset value gap is determined, the rotating blade assembly is directly connected onto the rotor 20 through the pressing plate 50 and the corresponding screw, so that the rotor 20 of the crusher is not required to be adjusted, the downtime is greatly reduced, and the start-up rate is improved.

Furthermore, the pre-adjusting device for the blade gap of the crusher further comprises a positioning screw 5, the positioning screw is in threaded connection with the adjusting body 1, in the specific operation, the positioning screw 5 can be screwed in or screwed out towards or away from the rotating blade 2, and therefore the rotating blade 2 is guaranteed to be close to the groove vertical wall of the groove 11 in the gap adjusting process, the accuracy of gap adjustment is improved, meanwhile, the position reliability of the rotating blade 2 in the gap adjusting process can be guaranteed, and the gap adjusting process is facilitated.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
