Description

[Detailed Description of the Invention] The present invention relates to a support device for a round blade shaft having a rotatably driven round blade, such as in a meat slicer.

FIG. 3 shows the mounting portion of the round blade base 2 and the end cover 8 in the prior art. Conventionally, the attachment part of the end cover 8 of the round blade base 2 is provided with a pilot hole 13 concentrically with the axis of the round blade shaft 3.
3 is fitted with the spigot convex portion 15 of the end cover 8. This type of meat slicer makes the round blade base 2 as small as possible around the axis of the round blade shaft 3 compared to the round blade 4, and increases the distance between the cutting edge of the round blade 4 and the outer wall of the round blade base 2, and slices It is necessary to make it easier to receive the pieces of meat. Therefore, the inner diameter of the spigot hole 13 cannot be made larger than the outer diameter of the pulley 9. In the method of rotationally driving the round blade shaft 3 using the belt 10, there may arise a situation where the belt 10 has to be replaced due to problems such as the end of its service life or defective products. For the reason mentioned above, the belt 10 cannot be taken out or inserted through the spigot hole 13, so the round blade 4
This method has the disadvantage that it is necessary to perform the troublesome work of removing the belt from the round blade shaft 3, moving the round blade shaft 3 in the axial direction, removing the belt 10 from the pulley 9, and taking it out from the bottom of the machine base 1.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to improve the maintainability of this type of meat slicer.

The present invention focuses on the fact that the belt can be attached and removed by enlarging the hole in the end cover attachment part of the round blade base, and devises the relationship between the shapes of the round blade base and the end cover.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The round blade base 2 is erected and fixed at one corner of the machine stand 1, and pivotally supports the round blade shaft 3. A round blade 4 is attached to the front end surface of the round blade shaft 3, and a pulley 9 is fixed to the rear end. Center cover 5 has round blade 4
It fits loosely into a recess 6 provided on the front end side of the blade, passes through a through hole 7 provided in the axial center of the round blade shaft 3, and is attached to an end cover 8 attached to the rear end of the round blade base 2. The screws are fitted. Further, the center cover 5 protrudes from the end cover 8 and is screwed into a nut 16. The pulley 9 is connected by a belt 10 to a pulley 19 fixed to an intermediate shaft 17 that is pivotally supported by the machine base 1. Also, the intermediate shaft is belt 20
is connected to a motor 18 mounted on the machine base 1. At the rear end of the round blade base 2, a pilot hole 13 is provided concentrically with the axis of the round blade shaft 3, and a notch hole 14 is provided continuously with the pilot hole 13. The end cover 8 is provided with a spigot convex portion 15 that fits into the spigot hole 13, and is provided so as to close the spigot hole 13 and notch hole 14 of the round blade base 2. On the other hand, the meat box 12 is provided so as to be able to reciprocate toward the round blade 4 using a rail 11 fixed to the machine base 1 as a guide.

The rotation of the motor 18 causes the intermediate shaft 17 to rotate via the belt 20, and the round blade shaft 3 to rotate via the belt 10. The meat box 12 is reciprocated toward the round blade 4 using the rail 11 as a guide. When the belt 10 needs to be replaced due to damage or the like, the nut 16 is loosened and removed, the center cover 5 is turned to unscrew from the end cover 8, and the end cover 8 is removed from the round blade base 2.

Furthermore, in the drive method of the round blade shaft 3 using a belt, the intermediate shaft 17 is normally structured so that it can be moved between centers with respect to the round blade shaft 3 in order to adjust the tension of the belt 10. It can be removed from the pulley 19 by loosening the tension and removed from the notch hole 14 of the round blade base 2. Also, a new belt 10 can be inserted and set through the notched hole 14.

According to the present invention, since the pilot hole and the notch hole are successively provided at the rear end of the round blade base, there is no need to move the round blade shaft in the axial direction, and the belt can be inserted through the pilot hole and the notch hole. Since it is possible to replace it, it is possible to achieve an excellent effect of extremely good maintainability.
