Technical Field

The invention relates to the technical field of sausage twisting machines, in particular to a high-speed twisting machine and a natural sausage casing twisting mechanism and a natural sausage casing discharging pipe thereof.

Background

In the automatic production process of sausages, a casing after sausage casing is usually twisted by using a high-speed twisting machine (hereinafter referred to as twisting machine) to form a sausage with a plurality of sections and a fixed length.

A twisting mechanism of the conventional twisting machine is shown in fig. 7, and comprises a discharge pipe 1 ', a twisting die 2 ' sleeved at the rear end of the discharge pipe, and a driving device 3 ' for driving the discharge pipe 1 ' and the twisting die 2 ' to synchronously rotate; when the sausage casing twisting machine works, the sausage casing is sleeved on the discharge pipe 1 ', the rear end of the sausage casing penetrates through the outlet 2.1' of the twisting die 2 'and then is filled with meat materials output by the discharge pipe 1', the twisting die 2 'and the discharge pipe 1' and the sausage casing rotate synchronously, and the sausage body filled at the rear end does not rotate after being clamped by the traction mechanism of the twisting machine, namely the sausage body does not rotate and the sausage casing rotates to realize twisting.

The outlet pipe 1' of such a kink mechanism is usually smooth and is suitable only for the production of artificial protein casings 90 and not for the production of natural casings 91.

This is because the artificial protein casing 90 is a collagen artificial casing, is a dried casing with a hard texture, and is regularly stacked in a cylindrical shape (as shown in the upper view of fig. 8) after being manufactured, and has a large friction with the discharge pipe 1 ' after being fitted over the discharge pipe 1 ', and can reliably rotate along with the discharge pipe 1 ';

the natural casing 91 is animal casing (pig casing, sheep casing, etc.), which must be soaked in water before production, but has very smooth inner and outer walls after being soaked in water, the natural casing 91 sleeved on the discharge pipe 1 'is irregularly stacked (as shown in the lower drawing of fig. 8), the friction between the natural casing 91 and the discharge pipe 1' is small, when the natural casing 91 and the discharge pipe 1 'rotate relatively at high speed, the casing is twisted on the pipe before being pulled to the pipe opening of the discharge pipe 1' to form a twist, when the casing is separated from the pipe opening, the whole pipe rotates, the pipe opening is twisted instantly to form a small kink, and once a small subsequent intestinal body is twisted.

It is seen that the prior art is susceptible to improvements and enhancements.

To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

For convenience of description, the direction in which the casing is moved is defined as the rear, i.e., the right side in fig. 2; the front and back are reversed, i.e. to the left in fig. 2.

Referring to fig. 1-6, the present invention provides a natural casing kinking mechanism, which includes a discharging pipe 1, a kinking mold 2 sleeved on a rear end of the discharging pipe, and a driving device 3 for driving the discharging pipe and the kinking mold to rotate synchronously (as prior art, the structure of the prior art is not described in detail herein); the circumferential surface of the rear end of the discharge pipe 1 is provided with anti-slip threads 1.1 (see fig. 4 and 5).

When the sausage casing twisting machine works, a natural sausage casing is sleeved on the discharge pipe 1, the rear end of the sausage casing penetrates through the outlet 2.1 of the twisting die 2 and then is filled with meat materials output by the discharge pipe 1, the twisting die 2, the discharge pipe 1 and the sausage casing rotate synchronously, and a sausage body filled at the rear end does not rotate after being clamped by a traction mechanism of the twisting machine, namely the sausage body does not rotate and the sausage casing rotates to realize twisting. The anti-slip threads 1.1 can increase the friction force between the natural casing and the discharge pipe 1, so that the natural casing can reliably rotate along with the discharge pipe 1, and small kinks caused by relative rotation of the natural casing and the discharge pipe are avoided. The natural casing kinking mechanism can be produced by using natural casings.

The anti-slip threads 1.1 can be raised lines protruding from the surface of the tapping pipe 1 or recessed lines (see fig. 5); the indentations are preferred because the ridges will impress a print on the inner wall of the natural casing, which may crush the casing when the pressure is too great.

In some preferred embodiments, see fig. 3 and 6, the rear end of the twisting die 2 is provided with a brake rubber ring 4 for pressing the natural casing on the discharge pipe 1; the stopper rubber ring 4 is disposed coaxially with the discharge pipe 1, and an annular gap a through which the natural casing passes is provided between the inner side thereof and the circumferential surface of the discharge pipe 1. The friction between the natural casing and the discharge pipe 1 can be improved by pressing the brake rubber ring 4 on the outer wall of the natural casing, the natural casing is more reliably ensured to rotate along with the discharge pipe 1, and the rubber ring has elasticity and cannot crush the casing.

Further, as shown in fig. 3 and 6, a brake adjusting ring 5 is further arranged at the rear end of the twisting die 2, an internal thread is arranged at the front part of the brake adjusting ring 5, a corresponding external thread is arranged at the rear end of the twisting die 2, and the brake adjusting ring 5 is connected with the external thread through the internal thread; an installation cavity 5.1 for installing the brake rubber ring 5 is formed between the brake adjusting ring 5 and the rear end of the twisting die 2, the size of the installation cavity 5.1 can be adjusted by adjusting the connection length of the external thread and the internal thread (realized by rotating the brake adjusting ring 5), and the brake rubber ring 4 is arranged in the installation cavity 5.1. When the rotating brake adjusting ring 5 makes the installation cavity 5.1 become small, the brake rubber ring 4 can be extruded to ensure that the inner side of the brake rubber ring is radially extruded towards the discharge pipe 1, so that the annular gap a becomes small, the pressure of the natural sausage casing can be adjusted according to actual needs, and the anti-skidding effect is ensured.

Here, a locking mechanism, such as a locking screw, may be provided between the brake adjusting ring 5 and the twisting die 2 to prevent relative movement between the brake adjusting ring 5 and the twisting die 2 during operation.

In some embodiments, see fig. 6, the rear portion of the outer circumferential surface of the brake rubber ring 4 is a truncated cone shape with a smaller rear portion and a larger front portion, and the front portion of the inner circumferential surface of the brake rubber ring is a truncated cone shape with a smaller rear portion and a larger front portion; the wall of the installation cavity 5.1 is matched with the peripheral surface of the brake rubber ring 4. The brake rubber ring 4 having this shape is more easily deformed during adjustment, and thus more effective in adjusting the size of the annular gap a.

In some preferred embodiments, see fig. 3 and 6, the middle of the twisting die 2 is provided with a finishing plate 6, the finishing plate 6 is provided with a circular hole 6.1 coaxially arranged with the discharge pipe 1 and used for passing through natural casing, and the front part of the circular hole is in a truncated cone shape with a large front part and a small back part. As shown in the lower drawing of fig. 8, because the natural casing 91 is irregularly stacked when being sleeved on the discharge pipe 1, the stacking height of some parts is high, and the parts can be stuck when passing through the outlet 2.1 or the annular gap a of the twisting die 2, which affects the normal filling and twisting of the casing; here, the casing is smoothed out when passing through the circular opening 6.1, so that jamming of the casing at the outlet 2.1 or the annular gap a is avoided.

Further, as shown in fig. 6, the front end of the inner hole 2.2 of the twisting die 2 is in a truncated cone shape with a larger front part and a smaller rear part, and the front end of the outlet 2.1 of the twisting die 2 is rounded. When the stacking height of the natural sausage casing is too high, the stacking height is reduced by primarily arranging the front end of the inner hole 2.2 once, and then the natural sausage casing is smoothed out by the round hole 6.1, so that the smoothing effect is better; while the front end of the outlet 2.1 is rounded to avoid scratching the sausage casing.

In some preferred embodiments, see fig. 2, 4 and 5, a plurality of (i.e. at least one) vent grooves 1.2 are provided on the circumferential surface of the tapping pipe 1 in front of the non-slip threads 1.1, and the vent grooves 1.2 are uniformly arranged in the circumferential direction. Because air is filled between the natural sausage casing and the discharge pipe 1, the air can be moved forwards in the air discharge groove through the air discharge groove 1.2 and discharged (the front end of the air discharge groove 1.2 preferably extends to the front of the natural sausage casing), so that the air is prevented from entering the sausage to form a cavity.

The degassing channel 1.2 can be a straight channel extending in the axial direction of the tapping pipe 1 (as shown in fig. 2, 4, 5) or a spiral channel extending helically forward, but is not limited thereto. Wherein, the processing difficulty of straight flute is less.

Furthermore, an annular relief groove 1.3 can be provided on the circumferential surface of the tapping pipe 1, which relief groove 1.3 communicates with the rear ends 1.2 of all venting grooves. Air firstly enters the release grooves 1.3 and then is uniformly discharged along all the exhaust grooves 1.2, and the air is discharged more smoothly.

The invention also provides a high-speed twisting machine which comprises the natural casing twisting mechanism. The high-speed twisting machine can be used for production by using natural casings.

The invention also provides a discharging pipe which is the discharging pipe 1 in the natural casing kinking mechanism.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, which are substantially the same as the present invention.
