Description

[Detailed description of the invention] Industrial application field This invention has a round blade fixed at the front end, and a pulley attached to the back of the round blade shaft.The rear part of the round blade shaft is inserted into a bearing installed on the back of the tool post frame. The present invention relates to an improvement in the support structure of a round blade shaft in a meat slicer in which the round blade shaft is cantilevered only on the rear side.

Conventional technology A meat box is configured to reciprocate on a machine stand and feed out the loaded material from the front end face, and is supported by a cutter post frame installed on one side of the machine stand, and the blade face is attached to the front end of the meat box. A meat slicer equipped with a round blade that slices the material fed out of the meat box while rotating along a surface has a round blade shaft with the round blade fixed to the front end attached to the front part of the tool post frame. There are two types of blades, one in which both bearings are supported by two front and rear bearings attached to the front and rear parts, and another in which the round blade shaft is cantilevered only on the rear side as in the present invention (see, for example, Fig. 4).

Problems to be solved by the invention In the former case, which has double bearings as described above, due to the waterproof structure of the bearing attached to the front part, cleaning water flowing from the front of the turret frame to the round blade shaft flows into the turret frame. Since it completely prevents intrusion, it has an almost permanent waterproof effect, but the cost is high because bearings are installed in two places. In addition, this type of slicer swings the axis of the round blade shaft to the side,
On the side where the round blade cuts the material, it is necessary to keep the front edge of the meat box as close as possible to the reciprocating locus of the meat box, and keep the other side slightly away from it to maintain good cutting performance. The disadvantage is that the assembly work of coaxially aligning the axes of the bearings and fixing them with a slight lateral deflection in the horizontal direction is time-consuming and requires a skilled person. On the other hand, the latter, in which the round blade shaft is supported in a cantilever manner, is economically advantageous because it can be easily assembled at low cost because it has only one bearing, but it has the disadvantage that it is inferior in waterproof structure against water intrusion from the front of the turret frame. be. That is, as shown in Fig. 4, the conventional waterproof structure of this part consists of a single sealing plate b that fits tightly on the round blade shaft a, and a mounting plate c and a screw receiving plate d that are screwed to each other. Since the mounting plate c is fixed to the front part h of the turret frame g by sandwiching it in between, if there is even a slight gap between the seal plate b and the round blade shaft a, the cleaning water will leak into the turret frame. g
There is a drawback that water enters the inside of the tool post frame g, is scattered by the pulley i rotating within the tool post frame g, and easily enters the bearing j, which has relatively low waterproofness. It has been desired to develop a support structure for a round blade shaft in a meat slicer that can be supported in a cantilever manner and has high waterproofness.

Means to Solve the Problems Therefore, the present invention has been developed by fixing a round blade at the front end and inserting the rear part of the round blade shaft, which has a pulley attached behind it, into a bearing attached to the back of the tool post frame. In a support structure for a round blade shaft in a meat slicer in which the round blade shaft is cantilever-supported only on the rear side, a circular inner diameter hole corresponding to the round blade shaft diameter is provided on the round blade shaft between the pulley and the round blade. a spacer plate having a spacer plate, two inner and outer seal plates sandwiching the spacer plate, a mounting plate that covers the outer seal plate from the outside and is fixed to the front part of the turret frame, and a mounting plate that is screwed into the mounting plate. A receiving seat plate having a screw hole for screwing a set screw and extending further inside the inner seal plate is attached, and a draining portion extending from the inner diameter hole to the outer diameter directly below is attached to the spacer plate. A support structure for a round blade shaft in a meat slicer is provided.

Function As described above, the present invention is equipped with a spacer plate and two inner and outer seal plates sandwiching it between the round blade shaft, and the outer seal plate is covered with a mounting plate, and the inner seal material is attached along the inner seal plate. In addition to fastening the parallel receiving seat plate to the mounting plate with set screws, we also provided the spacer plate with a drainage part that reaches from the inner diameter hole to the outer diameter directly below.
Even if a gap is created between the outer sealing material and the round blade shaft and high-pressure cleaning water is sprayed into that gap, it will be blocked by the spacer plate and the inner sealing material and the pressure will be reduced, and the water draining section will be This prevents water from entering the bearing.

Embodiments Examples of the present invention will be described below with reference to the drawings.

In the figure, F is a turret frame installed on one side of the meat slicer stand, 1 is a bearing attached to the back part f' of the turret frame F, 2 is a round blade A fixed to the front end, Attach pulley 3 behind it,
A round blade shaft is supported in a cantilever manner by inserting the rear part 2' into the bearing 1, 5 is a spacer plate fitted to the round blade shaft 2 between the pulley 3 and the round blade A, 6 is a There are two inner and outer seal plates sandwiching the spacer plate 5. 7 is a mounting plate that further covers the outer seal plate 6 and is fixed to the front part f'' of the turret frame. 8 is screwed into the peripheral edge of this mounting plate. The spacer plate 5, the inner and outer seal plates 6, 6 are provided with a screw hole 10 on the periphery to be screwed into the set screw 9, and are placed along the inner side of the inner seal plate 6. The mounting plate 7 and the receiving seat plate 8 are mounted on the round blade shaft 2 in close contact with each other.The spacer plate 5, the seal plates 6, 6 and the receiving seat plate 8 are arranged as shown in FIG. , each has a circular inner diameter hole 11 corresponding to the outer diameter of the round blade shaft 2 to be attached, and in particular, the seal plate 6,
The inner diameter hole 11 provided in 6 is formed so as to be in close contact with the outer circumferential surface of the round blade shaft 2. 12 is a spacer plate 5
A draining portion 13 is formed by cutting an appropriate width so that it opens from the inner diameter hole 11 to the outer diameter, and the set screw 9 is inserted into the peripheral edge of the spacer plate 5 and the inner seal plate 6. This is a relatively spacious insertion hole.

The supporting structure of this round blade shaft configured as described above is such that cleaning water flowing down the round blade shaft 2 from the back surface of the round blade A or down the front part f'' of the tool rest frame F is connected to the mounting plate 7. Even if water enters between the outer seal plate 6 and the round blade shaft 2, the inner diameter hole 11 of the spacer plate 5
The pressure inside the turret frame F is sufficiently reduced, and the pressure is lowered by being guided by the draining part 12 without breaking through the inner diameter hole 11 of the inner seal plate 6, and it is released along the inside of the front part f'' without being scattered in the tool post frame F. The water will naturally flow down, and the bearing 1 will be completely waterproof from the washing water.

Effects of the invention According to the invention configured as described above and used as described above, a spacer plate provided with a draining portion is sandwiched and two sealing plates, the inner and the outer, are attached to form a circular shape. The bearing can be completely waterproofed from water that enters the turret frame through the blade axis.
There is a practical effect that a meat slicer with excellent waterproofness can be used without impairing the features of the simple support structure in which the round blade shaft is supported in a cantilevered manner by a single bearing.
