DD288760A5 - DEVICE FOR PRESSURE STORAGE BEFORE THE SNOW-SET IN MEAT HOLLOWS - Google Patents

Abstract

The invention includes a device for pressure storage before the cutting set in Fleischwoelfen. The screw outlet causes against the cutting set a rotating pulsating thrust, which leads to the tumbling of the cutting set. A high Verschleisz the cutting kit parts is the result. The proposal to set a pressure chamber between the screw outlet and the cutting set to compensate for this pulsating pressure, although brings an improvement of the axial thrust in the processed material, but does not prevent a backflow, since the processed material after leaving the last worm gear relaxes again in the pressure chamber. According to the invention, the last flight at the end face directed into the pressure space is provided with a surface extending parallel to the cutting set as a support and timing element in order to achieve a better flow of the material being processed into the cutting set.

Description

Field of application of the invention

The invention finds application in companies of mechanical engineering in the production of meat grinders.

Characteristic of the known state of the art

Meat grinders are known crushers in which the material to be processed is guided by conveyor and pressure screws against a simple or multi-part cutting set and crushed in the cutting set.

The pressure builds up with the last flight, which is to be understood as a rotating inclined plane. The Schneckongangende is considered as O-point.

The emerging from the last worm gear processing material causes a circular puliierende effect on the subsequent cutting set, whereby the blades and perforated discs are subjected to a changing load and thus a high 'wear.

To counter this disadvantage has already been proposed, the O-point of the working screw arranged downstream of a pressure chamber to achieve the most uniform axial thrust of the processed material in front of the cutting set and to avoid pulsating shock loads. However, it has been found that a reflux of the processed material is unavoidable, since the upcoming delivery pressure does not remain constant, but is still inferior to local pulsating fluctuations with the feed screw from the last screw.

Object of the invention

It is an object of the invention to reduce energy shocks of the drive in meat grinders to improve the quality and the Durchsalz the rolled material to be processed and reduce the wear in the cutting set.

Explanation of the essence of the invention

The invention has for its object to maintain the pressure built up in the pressure chamber before the blade after the working screw pressure in the processing material sine period of time to ensure a uniform flow into the cutting set.

According to the invention, this object is achieved by din working worm is designed so that the directed to the pressure chamber end face of the last Schnecker ganges one or more parallel to the cutting surface extending surface as a support and timing member whose size between 10mm and 100mm depending on the diameter Perforated disk is and the caster angle of the 1st knife edge 5-20 * behind the end of the support and timer is.

embodiment

The invention will be explained in more detail for example with reference to the accompanying drawings. Show it

Each flight of the working screw 1 is, if the curve is linear, to be considered as inclined plane. FIG. 1 shows the unwound last flight 4, specifically its front side 3.

By the arrangement of two support timers 6; 6 ', Fig. 2, the last screw thread 4, as shown in Figure 1, so that the inclinations 4 and 10 represent the slopes of the last flight 4 and the screw section 10 and the straight line 6; 6 'the support timers 6; 6 'clarify.

The arrangement of the support time member 6 at the outlet or Endo the Arheitsschnecke 1, the O-point 7, done in the form that the support tent member 6 is formed as parallel to the cutting surface extending whose size depending on the diameter of the respective perforated disc between 10mm and 100mm Hegt. The dimensions for the support timer 6 as a function of the diameter of the perforated disc:

0 82mm-10-15mm 0114mm -15- 20mm 0130mm-20-30mm 0160mm-20-30mm 0 200mm-30-60mm 0400mm-60- 100mm

When using two back-up timers 6; 6 'receives the last flight 4 a so-called screw section 10,

which, based on the circumference between 340 ° and 360 ° is arranged. Fig. 1 and

The first support timer β encloses the range between 180 ° and 200 °. The size specifications also correspond to the Support timer 6 '. The processed material is conveyed by the Arbeitsschnecko 1 with the screw threads 4 in the processing housing. It

reaches the last flight through the support and timing elements 6; 6 'In the pressure chamber 2 and the cutting set

Due to the course of the worm shaft of the working screw 1, it is compressed. With the geometric contours of the End 3 it is compressed in the pressure chamber 2 and thus enters the cutting set 5. The compression provides a Force storage in processed material ago. The resistance and the necessary crushing work in the cutting set 5 leaves

no fast power delivery of the processed material to the cutting set 5 too. The processing would be at a

Working screw 1 without support and timing elements 6; 6 'then directly into the penultimate auger without further force reduction

fall behind.

To initiate the stored forces in the cutting set 5, the support and timing elements 6; 6 'designed so that a

safe power reduction can take place. The trailing and timing member 0 trailing 1st knife edge 9 fulfills the conditions to be associated with the Nachlaufwiplel 8 to the working screw 1 at the end face 3 the end point of the support timer 6.

Thus, it is possible that the processed material can only penetrate into the cutting set 5 and of the following

1. Knife blade 9 to be cut off safely. The reordering of the 1st cutter bar with the knife edge 9 takes

the knife from the area of transfer of the processed material from the working screw 1 to the cutting set 5 out and so reduces the resistance of the cutting sets.

The size of the caster angle 8 is between 5-20 °.
