Abstract
The utility model provides a moving cutter applied to a refined cotton disintegrator. The structure is that the upper portion of the back face of the moving cutter inclines toward the front end face of the moving cutter with cutting edges, and the slant angle alpha is 1 degree to 3 degrees. The upper portion of the back face of the moving cutter is enabled to incline toward the front end face of the moving cutter with the cutting edges, and the slant angle alpha is 1 degree to 3 degrees. Thus, the moving cutter is enabled to form a cutter body structure with a certain conical degree. After being installed on a moving cutter disc, the moving cutter can be clamped by a moving cutter pressing block, and thereby the axial movement of the moving cutter can be effectively prevented in the process of high-speed revolution, and the occurrence of an accident that a fixed cutter inside the cotton disintegrator is broken is avoided. According to the moving cutter applied to the refined cotton disintegrator, defects that a traditional refined cotton disintegrator is low in working efficiency and has potential safety hazards are overcome, and the refined cotton disintegrator can be guaranteed to be high in working efficiency and safe and reliable in use.
Description
Technical field
The utility model relates to a kind of moving knife that is applied to purified cotton grinder.
Background technology
Purified cotton grinder mainly is comprised of motor, main shaft (movable knife disc axle), backplate (stationary knife seat), moving knife, stationary knife, screen cloth and frame etc.Described moving knife is connected in the cutter groove on the movable knife disc by the moving knife pressure knife block, and described stationary knife is connected in the cutter groove on the backplate by the stationary knife pressure knife block.During work, driven by motor main shaft High Rotation Speed, the purified cotton that enters working chamber is shredded under the repeatedly intersection of moving knife and stationary knife is sheared, and the purified cotton after the chopping falls into discharging opening by screen cloth after reaching certain fineness, drawn and see off by air-introduced machine afterwards.
Existing moving knife cutter hub is that front end face and the rear back side are the straight plate body that is parallel to each other, this structure of the cutter body on being installed to movable knife disc after, the moving knife pressure knife block that is stuck in moving knife cutter hub back can not be suppressed moving knife well, therefore, in the High Rotation Speed process of movable knife disc, axial float that will accidental moving knife.Because the blade of moving knife generally only is not more than the movement clearance of 0.5mm apart from the blade of stationary knife, so, this axial float of moving knife just will inevitably cause the damaged in collision of moving knife and border stationary knife, loses more seriously, has also had influence on the operating efficiency of purified cotton grinder.
The utility model content
The purpose of this utility model just provides a kind of moving knife that is applied to purified cotton grinder, is difficult for stuck problem with the moving knife that solves in the purified cotton grinder.
The utility model is achieved in that a kind of moving knife that is applied to purified cotton grinder, and the top at the rear back side of described moving knife tilts to the moving knife front end face with blade, and inclined angle alpha is 1 ° ~ 3 °.
Preferred inclined angle alpha is 1.1 °, 1.2 ° or 1.3 °.
The top at the back side behind the moving knife is tilted to the moving knife front end face with blade, and inclined angle alpha is 1 ° ~ 3 °.So just can make moving knife form structure of the cutter body with certain taper, on being installed to movable knife disc after, but just the driven knife pressure knife block is stuck, thereby effectively prevented the axial float in the High Rotation Speed process, avoided the generation of stationary knife accident in the machine that breaks.
The utility model has overcome the low drawback with there being potential safety hazard of traditional purified cotton grinder operating efficiency, can guarantee the efficient operation of purified cotton grinder, and is safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, moving knife comprises six faces, is respectively: comprise blade interior front end face 2, the rear back side 3 relative with front end face 2, the left surface that connects front end face 2 and the rear back side 3, right flank, on end face 4 and bottom surface 1.Its front end face of traditional moving knife and the rear back side parallel, and therefore traditional moving knife pressure knife block is generally rectangular configuration.And the front end face 2 of moving knife and the rear back side 3 are not parallel in the utility model, the top at the rear back side 3 forward end face 2 tilts, tilt angle alpha is 1 ° ~ 3 °, preferred embodiment be, described α is 1.1 °, 1.2 ° or 1.3 °, because the top at the rear back side 3 forward end face 2 tilts, therefore required moving knife pressure knife block is required to be wedge.
When fixing moving knife, the bottom surface 1 of moving knife is placed in the cutter groove on the movable knife disc, and the front end face 2 that makes moving knife is close to the cutter groove inwall on the movable knife disc, between the rear back side 3 of moving knife and the cutter groove inwall on the movable knife disc, place the moving knife pressure knife block of wedge shape, rely on the moving knife pressure knife block of described wedge shape that described moving knife is connected in the cutter groove on the movable knife disc securely, thereby can prevent the axial float of moving knife in the High Rotation Speed process, avoid the generation of stationary knife accident in the machine that breaks.
Have angle β between front end face 2 and the upper end face 4, β is 60 ° ~ 70 °, preferred embodiment is, described β is 65 °.Front end face 2 is mutually vertical with bottom surface 1.
Claims (2)
1. a moving knife that is applied to purified cotton grinder is characterized in that, the top at the rear back side of described moving knife tilts to the moving knife front end face with blade, and inclined angle alpha is 1 ° ~ 3 °.
2. the moving knife that is applied to purified cotton grinder according to claim 1 is characterized in that, preferred inclined angle alpha is 1.1 °, 1.2 ° or 1.3 °.
