Description

[0002] A minute roller's gap controllable flour mill,

The present invention relates to a milling machine in which dried agricultural products between rollers are put into a powder, and the distance between the rollers is finely adjusted to uniformize the size of the powder.

Agricultural products such as rice, beans, and pepper are dried and made into powder for use as a food seasoning or material, and these powders are usually crushed and processed between a pair of rollers rotating in opposite directions.

The size of the powder to be ground is different for each type of food. For example, red pepper powder in the spice of red pepper paste or tteokbokki is finely crushed, and red pepper powder in the usual size of kimchi or seafood is used for the red pepper paste or spicy pepper paste. The reason why red pepper powder is used in various sizes is because it depends on the size of the particles, the color and the turbidity are different as well as the texture, and the internal components such as capsaicin dissolve in the water.

For this purpose, powder milling has been developed to control the size of the powder. 1, a moving roller (not shown) is moved back and forth by the rotation of a gap adjusting handle 400 provided on both sides of the front face of the main body. Such branching is difficult for the user to rotate the both spacing handles by the same degree with both hands, and it is easy to release the spacing adjusting handle while the branching is in operation, but since it is difficult to tighten, And there is a difference in the intervals between the rollers, which makes it difficult to produce a uniform powder.

In order to overcome such disadvantages, the roller position adjusting device described in Korean Patent Laid-Open No. 10-2010-0038795 has been developed. 2, the screw shaft 602 screwed to the roller fixing frame cover 601 and the adjusting shaft 603 are coupled to each other by the worm gear box 604, The gap adjusting handle 400 is coupled to the bevel gear 605 and the left and right of the moving roller 10 are simultaneously adjusted by the rotation of the gap adjusting handle.

The middle of the adjustment axis is divided to compensate for the difference in the lateral distance between the rollers generated during the branching use. The split regulating shafts can be individually rotated by a vise flyer or a pipe wrench so that the powder is discharged uniformly over the entire outlet, and when the rollers are spaced parallel to one another, the ends of the regulating shafts contact each other on the flange 606 Lt; / RTI >

The engagement of the flanges is achieved by inserting bolts into the elongated holes 607 formed around the adjustment shaft and fixing them with nuts. In order to accommodate the different amounts of rotation between the adjustment shafts, the slots are formed in an arc shape about the adjustment shaft and are configured to have a plurality of flanges that are firmly connected to each other.

In the conventional roller position adjusting apparatus thus constructed, the flange connection becomes stronger as the number of slots is increased or the bolts and nuts are tightly tightened. However, when adjusting the left and right spacing between the rollers, the bolts and nuts are loosened There is a disadvantage that it is difficult to unfasten the fastened nut because the number of bolts and nuts is increased and it is troublesome.

In addition, it is difficult to assemble the bevel gear, the worm gear box, the flange, etc., and the manufacturing cost of the mill is increased due to the high machine cost.

Korean Patent Publication No. 10-2010-0038795

The present invention intends to provide a milling apparatus capable of finely adjusting a distance between rollers, a manufacturing cost is low, and an adjusting method is simple.

The present invention relates to a method of manufacturing a roller-fixed frame, comprising the steps of: forming a roller-fixing frame on the roller-fixing frame, the roller-fixing frame being rotatably coupled to the roller- A pair of guide brackets fixed to a front surface of the roller fixing frame and having guide members protruding from upper and lower portions of the bottom plate and having a first shaft hole formed therein, ; A slide bar configured to be able to move into and out of the pair of guide pieces and having a first screw hole at a position corresponding to the first shaft hole; A support cover which receives the slide bar therein and is fixed to the front of the guide member and has a pair of second shaft holes at positions corresponding to the first screw holes and a second screw hole at the center; An interval adjusting handle screwed to the second screw hole to move the slide bar back and forth; And a pair of spacing adjusting members screwed to the first screw hole and brought into close contact with the front surface of the bearing coupled to the moving roller through the first and second shaft holes, The distance between the movable roller and the fixed roller coupled to the bearing is adjusted by the movement of the interval adjusting member coupled to the slide bar, And the fine gap between the fixing rollers is adjusted.

The fine division of the roller according to the present invention enables fine adjustment of the gap between the rollers by turning the gap adjusting member to make powder of uniform size, Since the interval is adjusted, not only the interval is easily adjusted but also the fixed angle for fixing the interval adjusting member is not provided. Thus, since the left and right distance of the adjusted roller is not changed, the size of the powder is uniform. In addition, the constituent elements of the present invention are simple in structure and easy to manufacture through general cutting, easy to assemble, and widely used bolts, nuts, and angles are used.

Figure 1 - is a perspective view of a conventional shredding device for individually adjusting left and right gaps.
2 is a plan view of a conventional roller positioning device;
3 is an exploded perspective view according to an embodiment of the present invention;
Fig. 4 is a combined state diagram according to an embodiment of the present invention; Fig.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The general milling unit includes a plurality of gears that are engaged with the main body and allow the moving rollers to rotate in the opposite direction to engage with each other so that the grains and the like contained in the hopper at the top of the roller can be crushed by driving the power unit The fixing roller, which is connected to the driving motor and serves as a driving shaft, is fixed to the main body. The moving roller, which serves as a slave axis, is moved so that the gap between the rollers is adjusted. .

The bearings are coupled to both the rotary shafts of the fixed roller and the movable roller, and the bearings coupled to the fixed roller are fixed to the side walls of the roller fixed frame formed in a " And a separating spring is coupled to both sides of a bearing coupled to the moving roller and a bearing engaged with the moving roller to act to push the moving roller, The spacing between the rollers is controlled by pushing the bearings in the direction of the bearings coupled to the fixed rollers, overcoming the elasticity of the spacing springs.

1, the gap between the two rollers is adjusted in such a manner that both sides of the moving roller on the front side are pushed in the direction of the moving roller by using two gap adjusting handles coupled to both sides of the main body, As shown in FIGS. 3 and 4, the separator according to an exemplary embodiment of the present invention may be provided with spacing adjusting members on both sides of the body to finely adjust the gap on both sides of the moving roller, So that both sides of the roller 10 can be moved simultaneously to more precisely adjust the interval between the rollers.

Hereinafter, the configuration of the present invention will be described in detail with reference to FIG. The guide bracket 100 is fixed to the front of the roller fixing frame 2 which is fixed to both sides of the main body 1 and supports the bearings coupled to both sides of the roller. The guide bracket 100 is formed by protruding a guide piece 130 at the upper and lower portions of the bottom plate 110 to have a shape of ' A single shaft hole 120 is formed.

Inside the guide piece 130, a gap adjusting member 500 is screw-

Shaped slide bar 200 is inserted into and out of the slide bar 200. Both ends of the slide bar are formed with a first screw hole 210 at a position corresponding to the first shaft hole 120, (500) is screwed.

In the upper and lower portions of the slide bar, a slide bar is inserted into the guide piece 130 so that no clearance is formed. Each slide bar 200 is formed with a " The support cover 300 having a cross section is fixed to the guide piece 130. The support cover is open at the rear, and fastening holes (150) are formed in the upper and lower ends of the support cover and the guide piece, respectively, and are fastened with bolts. A second screw hole 320 is formed at the center of the support cover and a second screw hole 320 is formed on the left and right sides of the support cover to correspond to the first screw hole 210, Is inserted.

The end of the rotation shaft pushes the slide bar. When the gap adjusting handle is released, the gap adjusting handle 400, which is coupled to the second screw hole 320 to move the slide bar 200 back and forth, The slide bar is retreated by the restoring force of the spacing spring between the coupled bearings. The stop nut 410 is coupled to the rotation shaft of the gap adjusting handle so that the gap adjusting handle is not separated from the support cover. The pin 412 is inserted into the pin hole 411 formed through the rotation shaft and the stop nut 410 and the stop nut 410 is fixed to the rotation axis of the gap adjustment handle 400. [

In the process of grinding grain, the slide bar is subjected to a strong bending force. When a force opposing each other is applied to both ends of the slide bar supporting the gap adjusting member and the center of the slide bar supported by the gap adjusting handle 400, Since the bar may be bent, the material of the slide bar is preferably a special steel having a high carbon content, various metal elements added thereto, and internally tempered by heat treatment.

The gap adjusting member 500 is in close contact with the front surface of the bearing 30 that supports the moving roller 10 by connecting the first shaft hole 120 and the second shaft hole 310, Since the gap adjusting members are simultaneously moved, both sides of the moving roller are moved at the same interval. Therefore, the gap between the rollers can be easily and accurately adjusted with a single handle according to the size of the desired powder particles. Meanwhile, the head portion 510 of the gap adjusting member 500 may be formed in a hexagonal or rectangular shape so that the gap adjusting member 500 can be easily turned.

The gap between the moving roller 10 and the fixing roller 20 must be uniform throughout so that the size of the powder is made uniform over the entire surface of the roller. To this end, it is possible to easily match the intervals of the rollers when the fixing rollers and the moving rollers are completely in contact with each other before starting the branching, and then the both spacing adjusting members are fixed to the fixing angles to be described later.

The moving rollers are structured such that the right and left sides are equally moved by the gap adjusting handles, so that the left-right gap between the once-adjusted rollers is maintained for a long time. Fine adjustment is often not achieved when replacing a roller having a lifetime of 3 to 6 months, except that a foreign material is caught in the gear that drives the roller and one side of the gear is unevenly worn out.

During the crushing of the agricultural products between the rollers, a large force is applied to the rollers to push each other, and the agricultural products contained in the hoppers are not always evenly supplied throughout the entire length of the rollers. A fixed angle (L) formed at one side of the head portion 510 of the gap adjusting member 500 formed in a polygonal shape is formed so as to prevent the gap adjusting member from loosening, 520 are brought into close contact with each other to prevent the gap adjusting member from rotating. An arc-shaped elongated hole 330 is formed in the front surface of the support cover around the gap adjusting member 500 to fix the stationary angle 520 to the support cover 300, and the stationary angle 520 is fixed Is inserted into the elongated hole of the support cover through the fixed angle and fixed by the nut. It is preferable that the elongated hole 330 is formed at the center of the support cover so that the bolt inserted into the elongated hole does not touch the end of the guide member.

According to the present invention having the above-described structure, since the distance between the rollers is adjusted by a single handle, it is possible to easily and accurately adjust the distance between the rollers. If the size of the powder to be discharged is not uniform, , And the gap between the rollers can be finely adjusted by turning the gap adjusting member using a tool. In addition, since the fixed angle is provided to fix the adjusted gap adjusting member, even if the agricultural product is unevenly inserted between the rollers, there is no change in the left and right gaps between the rollers.

The constituent elements of the present invention are simple in structure and can be easily manufactured through general cutting, easy to assemble, and widely used bolts, nuts, pins, angles, and the like.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Modifications and variations will be possible.
