Description

  The present invention relates to a cereal / seed / solid resin mill for facilitating maintenance of hygiene and hygiene maintenance. More specifically, the present invention relates to a coarse powder or granule that is introduced into a stock hopper of cereal / seed / solid resin. Concerning grain, seed and solid resin milling machines that facilitate the maintenance of cleanliness and hygiene maintenance by easily pulling out the pulverizing roll means for pulverizing a certain stock into powder of a set particle size from the milling machine body It is.

  Conventionally, the stock feed roll means and the pulverizing roll means of this kind of grain / seed / solid resin mill are fixed to the main body of the mill, respectively. In the case of maintenance such as cleaning, renewing and replacing the grinding roll, and repairing, it is difficult to clean, disassemble, and assemble due to the structure that is crowded with narrow places, When replacement is necessary due to wear of the grinding roll, special tools, heavy load handling tools such as chain blocks, and multiple personnel are required to remove the grinding roll from the mill body, and the production work is lengthened. The time was forced to stop.

For this purpose, for example, to facilitate cleaning, the front door provided on the inclined upper side of the roll is attached with a hinge between the upper part of the front door and the frame, and the lower end of the front door is moved upward from the front side. The roll cover that rotates and is self-supporting on the upper side, and the roll cover that covers the outer periphery of the roll is formed of a main roll cover that covers the upper part of the roll and a feed roll cover that covers the guide chute. The first fulcrum shaft is interposed between the roll cover and the main roll cover can be folded to the feed roll cover side. The second fulcrum shaft is provided between the frame and the upper part of the feed roll cover. A structure in which the main roll cover is folded upward (see Patent Document 1) and a distribution disposed above the pair of mill rollers. It is based on a feeder system known per se with a roller and a metering device and is intended to improve hygiene and access in particular, as a subassembly on a frame that can be pivoted around a rotation axis. A dispensing device, a device that is performed by attaching a dispensing roller (see Patent Document 2), and the like are disclosed.
Japanese Patent Laid-Open No. 2002-177802 (first page, FIG. 1) JP-T-2001-523152 (first page, FIG. 1)

  However, the front door provided on the upper tilt side of the roll is attached with a hinge between the upper part of the front door and the frame so that the lower end of the front door rotates from the front side to the upper side and becomes independent on the upper side. The roll cover that covers the outer periphery of the roll is formed from a main roll cover that covers the upper part of the roll and a feed roll cover that covers the guide chute, and the first fulcrum shaft is interposed between the main roll cover and the feed roll cover. The main roll cover can be folded to the feed roll cover side, and a second fulcrum shaft is provided between the upper part of the feed roll cover and the frame, and the main roll cover is folded upward. With a possible configuration, the feeder gate feeder roll unit will remain firmly attached to the main body as before, and sufficient cleaning will be possible. Also, maintenance such as repair requires disassembly work in a narrow area, and in the case of parts replacement, roll replacement, etc., individual disassembly is required in a narrow area, and many heavy objects are handled for handling heavy objects. It takes time and is dangerous.

  It is also based on a feeder system known per se having a distribution roller and a dispensing device arranged above a pair of mill rollers and is intended to improve hygiene and access in particular, this improvement around the axis of rotation. If the metering device and the distribution roller are attached as a subassembly to a frame that can be pivotally supported, the feeder system remains assembled, and the inside of the machine that is deeply inside is cleaned of important parts in terms of hygiene However, there are also problems in maintenance such as repair and replacement of parts.

FIG. 6 shows the method of the present invention. It is a side view illustrating the mounting of the stock feed roll means embodiment of mill grain-seed-solid resin to facilitate the Maintenance Manual.

  That is, the grain / seed / solid resin mill for facilitating the maintenance of the present invention, as shown in FIG. 1, is symmetrically composed of two sets of mill bodies 1 separated by a partition wall and surrounded by a side wall 1b. Thus, a stock hopper 1a provided with an inlet tube is provided above each side wall 1b, a product discharge hopper is provided below, and a stock feed roll means 2 and a pulverization roll means 3 described later are provided at the center side. The following detailed description will be made only for a grain / seed / solid resin mill on one side.

  The stock hopper 1a is disposed above the grain / seed / solid resin mill, and has an inlet cylinder at the top, such as a pipe for supplying stock from a supply source in the upstream process. A feeder system is connected to receive and store the stock. Below the feeder feed opening / closing mechanism 2d. 2e. 2f, stock feed roll 2a and feeder gate opening / closing mechanism 2d. 2e. It has an inclined plate that touches 2f and squeezes downward from above, all the stock passes through the feeder gate, and a transparent window that allows the stock level to be seen from the outside on the side of the inlet cylinder. is there.

  Next, the stock feed roll means 2 is assembled to the feed roll fixing plates 2c on both sides fixed to the side walls 1b on both sides of the mill body 1 by bolts so as to be detachable. And a feeder gate opening / closing air cylinder 2d for adjusting the gap between the feeder gate and the like.

  Further, the fixed side crushing roll 31 and the moving side crushing roll 32 of the crushing roll means 3 have the stock stored in the stock hopper 1a passed through the feeder gate interval of the stock feed roll means 2 and transferred by the stock feed roll 2a. In order to pulverize the stock into a powder having a set particle size, it is arranged in parallel in the horizontal direction, and is driven by a grinding roll drive motor (not shown) provided in the mill body 1 and a belt, pulley, etc. Connected to each other and rotated relatively in the center direction.

  Furthermore, the rotating shaft 3a is made to protrude from each both ends of a pair of crushing rolls 31.32, and each rotating shaft 3a is rotatably attached to the bearing 3b, and this bearing 3b is bearing from below. The bearing 3c is supported and fixed to the base 3c, and the lower surface of the bearing base 3c is slidably brought into contact with the upper surface of the sliding base 1c formed on the side walls 1b on both sides of the milling machine body 1 to be described later. It is.

  The fixed-side roll bearing case 31a is rotatably supported by the fixed-side pulverizing roll 31 and is erected and fixed to the bearing base 3c. The moving-side roll bearing case 32a is an outer periphery of the moving-side pulverizing roll 32. The bearing stand 3c is pivotally disposed on the bearing base 3c by a pivot shaft 32b so as to be pivotable so as to be separated from the fixed side grinding roll 31 and the moving side grinding roll 32. The fixed-side roll bearing case 31a and the moving-side roll bearing case 32a are connected by a roll gap fine adjustment mechanism 3d described later.

  Next, the roll clearance fine adjustment mechanism 3d connects the fixed side roll bearing case 31a and the movable side roll bearing case 32a, which rotatably support the fixed side crushing roll 31 and the moving side crushing roll 32, and a screw By moving the movable side crushing roll 32 that can pivot by moving the rod inside and out, the distance from the fixed side crushing roll 31 is finely adjusted so that the powder has a desired particle size.

  Next, the sliding base 1c is formed on the side walls 1b on both sides of the milling machine body 1, and the upper surface forms a slide ridge protruding in a rail shape as shown in FIG. A slide concave groove is formed on the lower surface of each bearing stand 3c so as to straddle and is slidably mounted.
