Description

Tail sealing machine and tail sealing method for sleeving and shrinking intestine and casing

Technical Field

The invention relates to the field of automatic tail sealing equipment, in particular to a tail sealing machine for sleeving and shrinking a sausage casing and a tail sealing method.

Background

Commercially available casings or the like, such as collagen casings, plastic casings, cellulose casings or natural casings, are usually shrunk into hollow circular tubes for filling enterprises to improve production efficiency. It is desirable to seal one end of the casing or the like before filling into the casing or the like to prevent the material from rushing out of the casing when filling is initiated. The common tail sealing method is knotting tail sealing or folding tail sealing. When filling the first section of the filling machine, the filling material of the first section is usually pushed out of the casing from the front end after filling due to inaccurate filling. The knotting and tail sealing operation is complex, and the tail sealing is difficult to untie, so that the difficulty in processing when the first section of filling material is recovered is high, and the tail sealing needs to be untied or cut manually. The automatic knotting tail sealing machine has the advantages of complex structure, high cost, low working efficiency and waste of sausage casings with certain length in the knotting operation process. The folding of the seal is relatively simple, but there is a problem that the seal is too loose, which results in a very easy leakage of the filling material.

Therefore, there is a need for a sausage casing tail sealing machine with high automation degree, tail sealing strength which can not cause leakage of tail sealing materials, and easy tail sealing unlocking.

Further, as shown in fig. 5, in another embodiment provided by the present invention, the transfer mechanism 100 includes: a plurality of L-shaped retainer plates 128, a second cylinder 124, and a pressure plate 110. A plurality of L-shaped material-bearing plates 128 are slidably connected, and a first groove 112 for bearing the telescopic sausage casing 600 is formed between every two adjacent L-shaped material-bearing plates. A plurality of L-shaped retainer plates 128 form an M-like shape.
