Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crusher suitable for crushing plastic materials.

Conventionally, a drum rotatably disposed within a casing is provided, and this drum has around its periphery a portion of the fixed knife which is oppositely oriented, and when the plastic material is loaded, the plastic material is completely removed. There are already 1 classifications of pulverizers that are configured to be cut into 9 pieces by the action. The crushed plastic material is used by being mixed with the virgin material during injection molding.

However, such conventional grinding! Moreover, it generates noise during operation, requires a high-output drive motor, and the production volume is low. Moreover, in conventional crushers, in order to ensure that the crushed particles can be homogeneously mixed with the virgin material,
Once pulverized plastic material usually needs to be re-pulverized several times to make the particles sufficiently small. Therefore, in this invention,
In particular, it has been provided to eliminate the above-mentioned inconveniences. In order to achieve this object, the present invention provides a crusher comprising a drum rotatably disposed opposite to the knives in a crushing chamber surrounded by a casing and having teeth. A plurality of tIRs are defined by a line segment extending in the length direction and inclined with respect to the axis of the drum (6), and the teeth of the part or the part are extended in the length direction of the drum (6) to generate a plurality of tIRs. The knife has a group for dividing into pieces of wood, and the knife consists of mutually parallel blades of *a, these blades are fixed to the casing, and the group number is 111! Please contact the department.
Ru.

In this invention, it is preferable that the thickness of the blade is substantially equal to the thickness of the group. Also, in this invention, it is preferable that the drum is constructed as a single unit. In 44 Ming, the valley fixing shaft for fixing the blade consists of two parts connected by screws and having a bare part, and these parts move relative to each other by the screws to fix the blade. I prefer it to be made up like this.

Furthermore, in this invention, the fixing mechanism is (to) -tl;
The two blades of the knife, which are arranged in the member and separated by this fixing mechanism, are connected to the two m* blades of the comb-like member.
s t'a! It is preferable that this is accepted, and the present invention will be applied below to explain this development @8 on the basis of an example. Peng board (

), the shaft (3) is attached to the casing (4) surrounding the grinding chamber (5).
It's better to get pregnant. And at the lower end of the crushing chamber (5J) there is a knife (force and

), and this tub (8) is provided with a sleeve (at)% as required.
A magnet is attached to the hopper (1), which is provided through the wall of the tub (8) and configured so that the pulverized particles can be sucked out and guided directly into the hopper (1) after injection molding. The body (9) is attached to the O-pin a' to prevent metal gl or molten metal mixed into the plastic material from being guided to the lower end of the hopper (1), and also Screen α
It has the role of supporting 1. The drum (6) has a part (61) formed in an arc shape to fit around the outer circumference of the drum (6), and is supported by a pin αυl at the other end. And this part (61)
V a cutting edge which extends along the length of the drum and is bounded by a line segment (62) which is located within the X--X axis of the drum (6). The line segment (62) has a spiral shape.

As already described with reference to FIG. minutes depending on the
It's hot.

Preferably, the drum is fabricated from a single piece.

In this case, #11 (63) is obtained by first cutting the single piece in the length direction to form a part (61), and then cutting in an annular direction in the direction to form a group (64). Just configure it.

The shaft end portion (65) of the drum (6) is rotatably mounted on the casing (4) via a roller bearing. These shaft end portions (6
5) has at least one hole (66
) is installed, and the plastic material scraps that are still hot from the injection molding machine are also loaded.
It is designed so that it can be crushed into pieces.

Moreover, by this W& placement, the production amount of particles can also be improved.

That is, the drum (6) and the knife (7) that s*J,
It consists of a plurality of blades (8) parallel to each other and having a rectangular cut WJ. These blades have casings (4
) at the end of the blade so that the teeth (63) engage the threshold group (64). In this way, the plastic material consists of the tooth piece (63) and the blade (7).
1) is crushed by the shearing action that occurs at the threshold. The size of the pulverized particles corresponds to the distance between two wi elementary pieces (6s) that are hardened next to each other.

It should be noted that at this distance, in most cases, the particles produced are small enough to allow light to pass through the screen a, so that the particles once crushed need to be carried around the drum enclosure 9 to undergo crushing again. In this way, this device can improve the output of the crusher. In addition, the production amount is the inner wall (41) of the casing (4) and the drum <67
The distance between the outer periphery of the blade (71) gradually decreases and the distance between
The fact that the E3 wall (41) is in contact with the drum (6) provides a further -Nk improvement. That is, by forming it in this way, it is impossible for the plastic material gripped by the teeth (61) to be pushed out through the passage of the teeth. What is it about Gerastec material?
(7), and as a result, they are inevitably crushed by the shearing action of the granite pieces.

Moreover, despite this increase in production of crushing equipment,
It is possible to drive this device with an electric motor of relatively small output. This is because the curve (62) defining the cutting edge of the tooth (61) is inclined with respect to the drum X-X axis, and as a result, the plastic material for any one part (61) This is because the crushing action is carried out along the teeth in a time-wise manner every m intervals. Therefore, in case of crushing i
This means that the driving force required to rotate the drum (6) is substantially much smaller than in the conventional case. This is because the grinding work is distributed substantially evenly over the surface of the drum. The mutually parallel blades (71) constituting the knife (7) are engaged with the shape collecting group (64) beyond the base of the blade or the base of the teeth (61) ↓
Such a configuration would also increase the live weight of the collar, as the weight would be lower. The reason is that along both sides of the valley blade (71) during crushing, M9iMIm (6+
) will occur at a depth equal to -.

The combination of the drum (6) and the knife (7) described above has significant effects such as an increase in the production of pulverized plastic material and a reduction in the required driving force.

These two effects are combined with the fact that the drum (6) can be rotated at a much lower speed than conventional grinding devices. Hidden inside, the sound of the crusher's prayers fades away.

In addition, the use of the submerged and individually independent blades (71) that make up the knife (7) has the effect of increasing the life of the knife by four times. This is because the two sets of opposing edges at each end are brought to the working position and used as a rudder. In addition, since each blade can be adjusted independently at 1SZ in the length direction of the blade, the blade can be mounted closer to the center of the drum (6) formed by the base strands of the group (64). The fact that (71) is installed in each position is a town rudder, which means that the remaining blades can be installed at the same time as Ml.
, even if it is not possible, replace only one of the sheets as necessary.

The walls of the casing (4) are attached to these blades (71), which are essentially the same width as the - of the group (64), by means of a comb-like member α4 having a comb-like component on the upper surface consisting of a comb-ta portion (121). Buy and hold tight. And the above compensation #

(see figure).

This fixing mechanism consists of two parts (13+X13z), which generally have a cross section of Tm and are connected to each other by screws I.

The vertical arm of Tm of these parts (13+) (162) has a wedge shape as shown in (135X13d).
