DISCLOSURE OF THE INVENTION The present invention provides a rotary molding drum of a food molding machine in which a metal abrasion slag caused by friction is prevented from being generated and which extends over the peripheral surface of the rotary molding drum and above the rotary molding drum. It is an object of the present invention to devise a configuration in which the molding raw material does not leak from a region between the peripheral surface and the contact surface of the rotary molding drum of the upper umbrella type drum stabilizer closely arranged.

[0004]

The object of the present invention is, as described in claim 1, a rotary molding drum of a food molding machine, which is provided with a plurality of molding dies around the rotary molding drum. In the region of both ends in the length direction of the machine, a seal groove and a seal member fitted in the seal groove are provided on the circumference, and they are in close contact with each other under the kneading container support and over the rotary molding drum. A sealing groove and a sealing member fitted in the sealing groove are provided on a contact surface of the upper umbrella type drum stabilizer which is arranged with the rotating drum, whereby a mold for the rotary molding drum is passed from the kneading container through the raw material dropping hole. The molding material fed into the inside of the rotary molding drum is tightly closed by the gap between the peripheral surface of the rotary molding drum and the contact surface between the peripheral surface of the upper umbrella type drum stabilizer and the rotary molding drum. Face and upper umbrella type drum cheap The problem is solved by the rotary molding drum of the food molding machine, wherein leakage from the region between the contact surface of the rotary molding drum and the peripheral surface of the rotary drum is prevented. To be done.

[0005]

According to the rotary molding drum of the food molding machine of the present invention, the molding raw material fed from the kneading container is dropped onto the rotary molding drum through the connection between the rotary molding drum and the kneading container. In this case, there is no leakage of molding raw material from the region between the peripheral surface of the rotary molding drum and the contact surface between the peripheral surface of the rotary molding drum of the upper umbrella type drum stabilizer, and the peripheral surface of the rotary molding drum and the upper umbrella type drum. There is no generation of metal slag due to direct friction with the drum stabilizer, and the loss of the molding raw material due to the leakage of these materials and the troublesome contamination of the post-treatment in the area of the production line are prevented in advance.

Further, the rotary molding drum of the food molding machine according to the present invention is capable of molding a molded product from a molding raw material at a high speed between a kneading container and a molded product conveying conveyor by a rational structure, and forming the molded product itself. There is no problem such as mixing of foreign matter.

[0007]

1 and 2, a kneading container support base 2 is mounted on a mechanical base 1, and a kneading container 4 is mounted on the kneading container support base 2. The kneading container 4 has a raw material dropping hole 4 corresponding to the raw material dropping hole 3 of the kneading container supporting base 2.
It has a on its bottom plate. The bottom plate of the kneading container 4 is rotatably supported by a method (not shown), and is provided with an arm-shaped or two-arm-shaped kneading blade 5 which is rotationally driven by an electric motor (not shown). The kneading blades 5 serve to knead the forming raw material in the kneading container 4 and to feed the forming raw material from the raw material discharging hole 4a onto the rotary forming drum 10 described later. An upper umbrella-type drum stabilizer 6 is attached to the lower surface of the kneading container support base 2, and the upper umbrella-type drum stabilizer 6 is disposed in close contact with the rotational molding drum 10 so as to straddle the rotational molding drum 10. There is. The upper umbrella type drum stabilizer 6 also has a raw material dropping hole 7 corresponding to the raw material dropping hole 3 of the kneading container support 2. Below the upper umbrella-type drum stabilizer 6, a shaft 13 of a rotary molding drum 10 is also rotatably supported on the machine base 1. A seal groove 11 is provided on the peripheral surface of the rotary molding drum 10 at both ends in the lengthwise direction, and a seal member 12 is fitted into the seal groove 11. Inside the upper umbrella type drum stabilizer 6, the rotary molding drum 1
The seal groove 8 is provided at two locations along the edge of the raw material dropping hole 7, which is the contact surface with the peripheral surface of 0, and the seal member 9 is fitted into the seal groove 8. The sealing members 9 and 1
Due to the close configuration between the peripheral surface of the rotary molding drum 10 and the contact surface of the upper umbrella type drum stabilizer 6 with the peripheral surface of the rotary molding drum 10 by 2 the tightness of this area is guaranteed and the molding material Leakage is prevented. Seal groove 7 shown
Is a straight line, but in order to secure the tightness between the rotary molding drum and the upper umbrella type drum stabilizer 6, it is an endless type which surrounds the raw material dropping hole 7 of the upper umbrella type drum stabilizer 6. An endless seal member may be fitted in the seal groove.
The seal member can be made of an elastic material such as synthetic rubber, synthetic resin or an inorganic material, or a metal having high abrasion resistance.

The rotary molding drum 10 is provided with a plurality of mold recesses 14 on the circumference, in the illustrated embodiment at two places, and a mold bottom plate 15 is provided at the bottom of the mold recess 14 in the mold recess 14. The mold bottom plate 15 is provided so as to be able to protrude and retract.
The guide bolt 16 is fixed to the rotary molding drum 1
A weight fixing nut 17 is connected to the weight 18 in a region protruding inward in the radial direction from the mold wall of the zero.
Are connected to prevent the weight 18 from being disengaged. Accordingly, when the rotary mold drum 10 is rotated in the direction of the arrow 21 and the mold recess 14 is located immediately below the kneading container 4, the mold bottom plate 15 is rotated by the weight of the weight 18 for embedding the molding material. 10 radially inwardly, whereby the molding material is filled into the mold recesses 14 and furthermore when the rotary molding drum 10 is rotated in the direction of the arrow 21, the mold recesses 14 are lowered and thus the molded article transport conveyor. When moved to the position facing 22, the weight of the weight 18 causes the mold bottom plate 15 to protrude outward in the radial direction of the rotary molding drum 10 to discharge the molded product, and the molded product 20 is lowered onto the conveyor 22. . As shown in the drawing, a weight 18 is used as a drive mechanism for moving the mold bottom plate 15 in and out of the mold recess 14,
A configuration in which the mold bottom plate 15 is made to protrude and retract through the guide bolts 16 against the force of the restoring spring by a cam attached to the shaft 13 is also possible. A shaping wire 19 made of a piano wire is stretched over the entire length of the rotary molding drum 10 between the rotary molding drum 10 and the molded article conveying conveyor 22 and in contact with the outer peripheral surface of the rotary molding drum 10. Both ends are fixed to the machine base 1 by a method not shown. The shaping wire 19 is provided for shaving off a surplus raw material portion projecting beyond the outer peripheral surface of the drum from the mold concave portion 14 of the rotary molding drum, that is, for shaping a molded product. Conveyor 22
The molded product 20 pushed down can be conveyed by the movement of the conveyor 22 in the direction of the arrow 23 and supplied to the flying device through the next step of the manufacturing line, for example, the drying device, or directly to the flying device.

The rotary molding drum of the food molding machine according to the present invention further molds a molded product, that is, a food product from the molding raw material at a high speed between the kneading container 4 and the molded product conveying conveyor 22, and at the time of mixing of foreign matters, It is possible to prevent aluminum slag from being mixed due to friction between the rotational molding drum 10 and the upper umbrella type drum stabilizer 6.
