Description
Technical Field
The utility model belongs to the technical field of plastic crushing equipment, and particularly relates to a lifting rotary opening and closing structure of an upper shell of a plastic crusher.
Background
The plastic crusher is generally used for crushing waste plastics and plant plastic scraps so as to recycle, and granules obtained by crushing through the crusher can be directly used for an extruder or injection molding, and can also be recycled through basic granulation.
The plastic crusher is mainly composed of a feeding hopper, a pressing device, an upper shell, a main shaft and a lower shell, wherein the feeding hopper is installed above the upper shell, a supporting arm for lifting, rotating and opening is welded on the upper shell, a fulcrum is arranged at one end of the supporting arm, the main shaft is fixed in the middle of the lower shell through a bearing, a movable cutter blade is installed on a cutter holder of the main shaft, and fixed cutters are installed on two sides of the main shaft of the lower shell. When the blade is adjusted in the dismouting, need open the upper housing so that carry out dismouting blade operation. However, the pivot points arranged in the upper shell lifting rotary opening and closing structure of the existing plastic crusher are all between 5cm and 20cm away from one side of the lower shell. After the shell is opened and lifted and rotated, the distance between the upper shell and the lower shell is very close because the distance between the fulcrum is short, and the body of an operator cannot enter between the opened upper shell and the opened lower shell at all, so that the dismounting and the adjustment of the fixed cutter on one side of the fulcrum of the lower shell are very difficult, sometimes, the blade on the other side is replaced for three times, the blade on one side of the fulcrum is replaced for one time, the trouble is saved for a picture, the blade on one side of the fulcrum is not replaced for some times, the efficiency of the crusher is reduced for a long time, and the power consumption is increased.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a lifting rotary opening and closing structure of an upper shell of a plastic crusher, which has a more reasonable structure and more convenient blade assembly and disassembly.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the upper shell of the plastic crusher is lifted and rotated to open and close the structure, mainly composed of a rotary supporting arm and a hydraulic cylinder; the lower shell of the plastic crusher is fixed on one side of the base, and the other side of the base is provided with a fixed supporting plate; the fixed end of the rotary supporting arm is fixedly connected to the upper shell, and the movable end of the rotary supporting arm is arranged at the upper end of the fixed supporting plate by a movable shaft; one end of the hydraulic oil cylinder is arranged on one side of the fixed end of the rotary supporting arm by a movable shaft, and the other end of the hydraulic oil cylinder is arranged on the outer wall of one side, close to the fixed supporting plate, of the lower shell by a movable shaft.
And a limiting plate is arranged on the outer side of the upper end of the fixed supporting plate.
Aiming at the problem that a fixed cutter at one side of a lifting rotary fulcrum is difficult to disassemble, assemble and adjust when an upper shell of the existing plastic crusher is opened and closed, the inventor designs and manufactures a lifting rotary opening and closing structure of the upper shell of the plastic crusher, and the lifting rotary opening and closing structure mainly comprises a rotary supporting arm and a hydraulic oil cylinder; the lower shell of the plastic crusher is fixed on one side of the base, and the other side of the base is provided with a fixed supporting plate; the fixed end of the rotary supporting arm is fixedly connected to the upper shell, and the movable end of the rotary supporting arm is arranged at the upper end of the fixed supporting plate by a movable shaft; one end of the hydraulic oil cylinder is arranged on one side of the fixed end of the rotary supporting arm by a movable shaft, and the other end of the hydraulic oil cylinder is arranged on the outer wall of one side, close to the fixed supporting plate, of the lower shell by a movable shaft. The utility model has more reasonable structural design, and when the upper shell of the plastic crusher is applied to the plastic crusher, the body of an operator can enter the position between the upper shell and the lower shell to carry out the dismounting and the adjusting operation of the blade after the upper shell is lifted, rotated and opened in place, thereby overcoming the problem that the blade at one side of the fulcrum of the upper shell at two ends is difficult to replace, improving the efficiency of replacing the blade, reducing the labor intensity and further saving the labor cost.
Drawings
FIG. 1 is a schematic diagram of the structure and the closed state of the upper shell lifting rotary opening and closing structure of the plastic crusher.
Fig. 2 is a schematic view of the structure and the opening state of the upper shell lifting rotary opening and closing structure of the plastic crusher.
In the figure: the cutting machine comprises a lower shell, 2 first fixed blades, 3 first fixed blade seats, 4 second fixed blade seats, 5 second fixed blades, 6 fixed supporting plates, 7 main shafts, 8 movable blades, 9 upper shells, 10 feed hoppers, 11 rotary supporting arms, 12 rotary supporting points, 13 hydraulic oil cylinders, 14 bases and 15 limiting plates.
Detailed Description
As shown in figures 1 and 2, the upper shell lifting rotary opening and closing structure of the plastic crusher mainly comprises a rotary supporting arm 11 and a hydraulic oil cylinder 13. Wherein,
the lower shell 1 of the plastic crusher is fixed on one side of a base 14, and a fixed support plate 6 is arranged on the other side of the base; the fixed end of the rotary supporting arm is fixedly connected to the upper shell, the movable end (a rotary fulcrum 12) of the rotary supporting arm is arranged at the upper end of the fixed supporting plate by using a movable shaft, and the outer side of the upper end of the fixed supporting plate is provided with a limiting plate 15 (higher than the fixed supporting plate) so as to avoid excessive opening and closing; one end of the hydraulic oil cylinder is arranged on one side of the fixed end of the rotary supporting arm by a movable shaft, and the other end of the hydraulic oil cylinder is arranged on the outer wall of one side, close to the fixed supporting plate, of the lower shell by a movable shaft.
The hydraulic oil cylinder for supporting and jacking can also be replaced by a telescopic screw rod according to requirements.
When the hydraulic cylinder 13 is ejected, the upper shell 9 and the feed hopper 10 are ejected and rotate to open around the rotation supporting point 12, and when the opening is at the maximum, the limiting plate 15 is pressed against the rotation supporting arm 11 to prevent the excessive opening.
When the hydraulic ram 13 is retracted, the upper housing 9 and the feed hopper 10 will be lowered around the rotation support point 12 and the closing is completed when the lower housing is in contact with the upper housing.
