Method and device for extruding and shrinking casing

Abstract

The invention discloses a method and device for extruding and shrinking a casing, and belongs to the technical field of casings. The device comprises a rack, and is characterized in that the rack is provided with a first moving support and a second moving support which can move in opposite directions, the first moving support is provided with a first extrusion head, the second moving support is provided with a first plier arm and a second plier arm, the first plier arm and the second plier arm are connected with an opening and closing mechanism, a first split body is arranged on the first plier arm, a first clamping groove is formed in the first split body, a second split body is arranged on the second plier arm, a second clamping groove is formed in the second split body, the second clamping groove can be in butt joint with the first clamping groove to form a clamping hole, and the first split body and the second split body form a second extrusion head; and the second extrusion head and the first extrusion head are distributed oppositely. By means of the device, the two ends of the casing shrinkage pipe can bear extrusion force at the same time to be compacted towards the middle, the compactness of the casing shrinkage pipe can be improved, and disjunction is avoided; and the pipe wall of the casing shrinkage pipe is arched outwards, so that the hole in the casing shrinkage pipe is expanded, and the rod is convenient to separate.

Description

Technical field[0001]The present invention belongs to the field of casing, and more particularly to a method and apparatus for extruding a casing.Background technique[0002]The casing can extend the quality of the product to a certain extent, often in the field of food processing as a cooler to fill the sausage and enema, which is mainly divided into natural casings, collagen casings and polyvinyl chloride (PVDC) casings. Because natural casings have a substantially reliable manual operation and its own thickness, the collagen casing is convenient, good taste, high transparency, high diameter natural casings and PVDC casings that cannot be combined, and its compressive strength It is more than four times that of natural casings and is therefore widely used.[0003]In order to facilitate the transportation and storage of the casing, it is usually the lack of collagen casings into a sturdy and pruning tube, which is ready to achieve high-speed mechanical enema on the enema. In the proces...

Problems solved by technology

During the casing shrinking process, although the shrinking machine shrinks the flat stretch casing into a tubular shape, in order to prevent the casing from being disjointed or even loose, during the process of taking and transferring the casing, the staff usually Hold the shrunken casing with both hands, which greatly reduces the work efficiency

[0004] For this reason, those skilled in the art try to further squeeze and compact the shrunk casing and then discharge it through the unloading structure. The size of the middle hole of the shrinking tube of the casing is reduced, so that the shrinking tube of the casing is tightly placed on the receiving rod, which increases the difficulty of unloading, and also increases the difficulty of setting the enema rod, which affects the use of the downstream enema link
