The present invention relates to a juicer for extracting the juice by pulverizing, compressing the juice material such as vegetables or fruit by a mechanical method, it was invented to more effectively discharge the residue generated after the juice to increase the juice efficiency.

The juicer is a helical gear-type shredding roller part at the material introduction part, and the juice roller formed with a screw spiral feed roller at its tip is driven by being engaged with a pair of filter meshes to compress and crush the injected material and then surround the outer peripheral surface of the feed roller. It is configured to filter the material juice liquid crushed by the waste and to separate the discharge to the discharge side.

Conventionally, the juice roller is used to crush the material passing between the helical gear-type crushing rollers while engaged, and the screw helical feed rollers located at the distal sides of the cylindrical filter meshes surrounding the outer circumferential surface of the circumferential surface are separated from each other. It rotates inside and transfers the residue located between the filter net and the transfer roller to the outlet side.

Therefore, there is no problem in the shredding process of the shredding roller which breaks and compresses the material to form the juice, but the discharge process of forcibly compressing the material in the filter net, filtering the juice, and discharging the filtered waste There was a failure that could not be achieved.

The reason is that when the crushed material is transferred from the engaged position of the crushing roller, which is actually crushed and squeezed by the screw helical feed rollers separated from each other in the cylindrical filter net, After the teeth were sent to a non-interlocking space, the material located in these spaces could not be compressed or transported to the outlet side without any forced conveying means.

As a result, most of the material which is crushed by forcibly conveying the material crushed by the helical feed roller and substantially broken in the process of separating the juice liquid stays at the position of the screw spiral or is pushed very slowly and naturally. The effect of the juice was extremely fine.

In addition, there was a serious problem such as stopping the operation by unnecessarily a lot of time in the juice operation as a result of the material discharge is not normal, or severely entangled in the state filled with the material around the juice roller.

The present invention has been made in view of such a conventional situation, and an object of the present invention is to provide a juicer so that the discharge of the residue can be made more easily.

Another object of the present invention is to provide a juicer that can increase the juice efficiency by forcibly compressing the crushed material more effectively.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Consisting of;

The pressing rollers 28 and 28 'of the juice roller part 26 engage the screw threads 28a and 28b at least partially engaged with each other, and the casing 80 is a roller support liner therein. (24) The fixed installation is characterized by consisting of a fixed cover (14) and a detachable cover (24) detachably coupled to the tip side of the fixed cover (14).

Figure 1 shows the appearance of the juicer of the present invention, the front end of the motor casing 10 is coupled to the fixed roller casing 14 having a juice material supply hopper 12 and the front end of the fixed roller casing 14 The casing 80 is constituted by the separate cover 16.

As shown in FIGS. 2 to 4, a motor 20 having a rotating shaft 18 is installed in the motor casing 10 and communicated with a juice material supply hopper 12 in the fixed roller casing 14. The roller support liner 24 having the juice material supply hole 22 is coupled thereto, and is inserted into the rear end of the juice roller part 26.

The juice roller portion 26 is a crushing roller 30, 30 'having a helical spiral teeth 32, 32' in the material introduction position, and a crimping screw screw 28a, 28b on the discharge side. Feed rollers 28 and 28 'are formed.

The juice roller part 26 is inserted into the roller support liner 24 in a state in which the shredding rollers 30 and 30 'are coupled, and one side shredding roller 30 is connected to the rotation shaft 18 of the motor 24. The shaft hole 34 coupled to and drilled at the front end side of each of the pressing feed rollers 28 and 28 'is coupled to the shaft rod 40 formed on the hooking network support plate 38 of the strainer network assembly 36 which will be described in detail later.

The filter net assembly 36 is composed of a filter net 42 and a filter net support plate 38 for supporting the tip of the filter net 42 in a form surrounding the screw spiral 28.

The most important feature of the present invention is that the screw thread 28a, 28b is at least partially interlocked and installed in the state in which the compressed feed rollers 28, 28 'of the juice roller part 26 are installed. It is to increase the juice efficiency and the overall working efficiency by improving the compression and transfer capacity of the.

That is, as shown in FIG. 3, in the state where the material crushed by the shredding rollers 30 and 30 'at the introduction position of the material is transferred to the crimping feed rollers 28 and 28', the crimping feed roller ( By rotating the screw threads 28a and 28b of 28) and 28 'in engagement, it is possible to forcibly transfer the crushed material to the outlet side.

As shown in FIG. 5 and FIG. 6, the discharge hole 44 formed at the outlet side of the strainer support plate 38 is positioned on the same straight line as the engagement position of the screw threads 28a and 28b. It is easy to discharge the residue continuously.

At this time, the position of the discharge hole 44 is provided with a flexible discharge plate 48 to be responsive to the discharge pressure of the residue discharged from the inside, the degree of opening of the slot 46 cut in a substantially "+" shape It is variable and it is controlled to automatically regulate the discharge pressure.

The flexible discharge plate 48 is formed of a rubber material and a silicone rubber material having excellent flexibility and elasticity, and the slot 46 cut into an approximately " + " shape is in a normal free state when no pressure of the residue is applied. By maintaining the flat shape, the boundary of the slot 46 is brought into a closed state.

When the internal pressure is applied by forcibly conveying the debris compressed and crushed by the screw helix 28 located at the tip side of the juice roller part 26 to the position of the outlet side discharge hole 44. The slot 46 is spread outwardly in proportion to the discharge pressure to discharge the residue.

At this time, the discharge passage is formed by the slot 46, and as a result of the force acting to suppress the discharge direction and the reverse direction by the self-resilience to always restore, it will have an effect of compressing the juice liquid held by the residue .

Therefore, while suppressing the discharge of the residue and having a degree of opening appropriate to the discharge pressure, the juice efficiency is increased by reducing the discharge of the residue in a state where most juice is retained.

The flexible discharge plate 48 having this function is fixed by a method of screwing to the strainer support plate 38 with a screw 58 in a state where the fixing plate 56 having the opening portion 54 is attached to the outside.

In addition, in order to prevent the opening of the slot 46 from opening beyond the proper area due to over-pressure, the opening of the discharge limiting plate 52 is prevented from being opened or damaged beyond the elastic limit of the flexible discharge plate 48. good.

The discharge limiting plate 52 is fixedly installed together by the screw 58 between the flexible discharge plate 48 and the fixed plate 56, and the discharge hole 50 is drilled in the center thereof. As shown in Fig. 6, the convex portion 52a is formed to be convex in the discharge direction so that the slot 46 of the flexible discharge plate 48 can be opened to the position of the convex portion 52a. It will be limited.

Therefore, the limit can be set with an appropriate discharge pressure, and the flexible discharge plate 48 can be prevented from being damaged by forcibly opening above this limit.

In addition, the discharge limiting plate 52 may be formed of an elastic material made of a rubber material and silicone of a degree that can be elastically deformed in the state of overpressure, although less flexibility and elasticity than the flexible discharge plate 48.

On the other hand, the radial support liner 24 has a radial flange 60 formed on the leading edge side (see FIG. 2), and a coupling rod for coupling the separate cover 16 to both sides of the flange 60 ( 62 and 62 'are connected by hinge pins 64. These coupling rods 62 and 62 'are provided with a spiral portion 66 at their ends, and a fixing nut 68 is coupled thereto so that the nut 68 can be operated by hand.
