Description

Feed hopper pressing device of plastic crusher

Technical Field

The utility model belongs to the technical field of plastics crushing equipment, especially, relate to a feeder hopper press device of plastics breaker.

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 material pressing device, an upper shell, a main shaft and a lower shell, wherein the material pressing device is mainly used for forcibly feeding materials into the upper shell and the lower shell of the crusher so as to improve the working efficiency of the crusher. In the existing reciprocating material pressing devices, the movement tracks of the material pressing plates are all in up-and-down linear movement, and the material pressing devices are not provided with tracks and only limit the front-and-back and left-and-right displacement of the material pressing plates by the side walls of the feed hoppers. In this way, the pressure plate can generate friction with the side wall of the feed hopper, which causes great noise and serious abrasion; some press device is equipped with linear slide rail, but because the structure restriction, inside straight line slider and track all adorned at the feeder hopper casing, rugged work environment often makes the material often get into inside the card shell that leads to the fact of straight line slider, still remain remaining water, corrosive liquids, silt etc. in the broken waste plastic bottle also can lead to the fact the pollution to track and slider, even seriously corrode. If the abrasion of the rail and the sliding block is not repaired in time, the displacement of the pressure plate can be limited only by the friction between the pressure plate and the side wall of the feed hopper.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a feeder hopper press device of plastics breaker that the structure is more reasonable, the operation is more smooth and easy and stable durable.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the feeding hopper pressing device of the plastic crusher comprises a feeding hopper and a pressing unit, wherein the pressing unit mainly comprises a pressing plate, a side plate, a front baffle and a connecting rod; a rotating shaft penetrates through two side walls of the outlet position of the feed hopper, a shaft sleeve is arranged outside the rotating shaft, a material pressing plate and one end of a side plate are respectively connected to the shaft sleeve, the other ends of the material pressing plate and the side plate are respectively connected to two ends of a front baffle plate, and a material baffle plate is arranged on the inner wall of the feed hopper above one end of the front baffle plate connected with the material pressing plate; the pressure flitch inside wall sets up the connecting rod seat, and the connecting rod seat passes through the bearing to be connected with connecting rod one end, and the connecting rod other end passes through the bearing to be connected with the outer swing arm one end of feeder hopper.

The shaft heads at the two ends of the rotating shaft are arranged outside the two side walls of the feed hopper through bearings.

The other end of the swing arm is connected with a speed reducer.

Aiming at the problems of a material pressing part in the existing plastic crusher, the inventor designs and manufactures a feeding hopper material pressing device of the plastic crusher, which comprises a feeding hopper and a material pressing unit, wherein the material pressing unit mainly comprises a material pressing plate, a side plate, a front baffle and a connecting rod; a rotating shaft penetrates through two side walls of the outlet position of the feed hopper, a shaft sleeve is arranged outside the rotating shaft, a material pressing plate and one end of a side plate are respectively connected to the shaft sleeve, the other ends of the material pressing plate and the side plate are respectively connected to two ends of a front baffle plate, and a material baffle plate is arranged on the inner wall of the feed hopper above one end of the front baffle plate connected with the material pressing plate; the pressure flitch inside wall sets up the connecting rod seat, and the connecting rod seat passes through the bearing to be connected with connecting rod one end, and the connecting rod other end passes through the bearing to be connected with the outer swing arm one end of feeder hopper. The utility model discloses a movement track that rotation axis and connecting rod will press the flitch improves for circular arc reciprocating motion rationally, has effectively avoided the invasion of pollutant to rotation axis and bearing through axle sleeve protection rotation axis simultaneously, and the bearing rotation range is little, presses flitch and feeder hopper lateral wall frictionless operation more smooth and easy, and the noise is lower, and the performance is more stable durable.

Drawings

Fig. 1 is a schematic structural view of a feeding hopper pressing device of the plastic crusher.

In the figure: the device comprises a feeding hopper 1, a shaft sleeve 2, a side plate 3, a connecting rod 4, a swing arm 5, a connecting rod seat 6, a material baffle 7, a rotating shaft 8, a material pressing plate 9 and a front baffle 10.

Detailed Description

As shown in figure 1, the feed hopper pressing device of the plastic crusher comprises a feed hopper 1 and a pressing unit. Wherein the content of the first and second substances,

the pressing unit mainly comprises a pressing plate 9, a side plate 3, a front baffle 10 and a connecting rod 4; two side walls of an outlet of the feed hopper are provided with a rotating shaft 8 in a penetrating way (the side walls are provided with slightly larger round holes so that shaft heads of the rotating shaft can penetrate out), shaft heads at two ends of the rotating shaft are arranged outside the two side walls of the feed hopper through bearings, a shaft sleeve (a shaft sleeve pipe is fixed with the rotating shaft through a screw) 2 is arranged outside the rotating shaft, a pressure plate and one end of a side plate are respectively connected along the shaft sleeve, the other ends of the pressure plate and the side plate are respectively connected with two ends of a front baffle, and a baffle plate 7 is arranged on the inner wall of the feed hopper above the end, connected with the pressure plate, of the front baffle; the pressure flitch inside wall sets up connecting rod seat 6, and the connecting rod seat passes through the bearing to be connected with connecting rod one end, and the connecting rod other end passes through the bearing to be connected with 5 one end of swing arm outside the feeder hopper, and the swing arm other end is connected with the speed reducer.

According to the requirement, a hydraulic oil cylinder can be used for replacing the speed reducer, one end of the hydraulic oil cylinder is fixed on the connecting rod base through a movable shaft, and the other end of the hydraulic oil cylinder is fixed on the feed hopper shell through a movable shaft.

When the speed reducer drives the 5 swing arms to rotate, the 4 connecting rods can present a reciprocating motion, and the 9 pressure plates and the 10 front baffle plates are driven by the 4 connecting rods to generate a reciprocating motion with an arc-shaped track around the 8 rotating shafts. When the link point of the 5 swing arm and the 4 connecting rod swings to the far end away from the feed hopper 1, the 9 pressing plate and the 10 front baffle plate are also lifted to the high position, and when the 5 swing arm rotates by 180 degrees continuously, the 9 pressing plate and the 10 front baffle plate are also lowered to the low position under the transmission of the connecting rod. When the 5 swing arms rotate for one circle, the 9 pressing plates and the 10 front baffle plates complete the ascending and descending actions of a circular arc track.
