Description

TECHNICAL FIELD

[0002] In the field of food processing, especially in the production process of sausage and other sausage products, the cutting and separating of sausage strings is a key link. The traditional sausage string is usually a long continuous sausage string formed by continuous wrapping of sausage casings. The existing cutting and separating method is generally to directly put the whole continuous sausage string into a drum-type sausage cutting machine for cutting and separating, so as to cut the connection of each sausage and realize the single separation of sausages. However, this traditional direct cutting method has many disadvantages. Since the drum-type sausage cutting machine cuts the whole sausage string, the sausage string is long and has high integrity, and during the cutting process, the sausage string is easily shaken and unevenly stressed, which leads to a high breakage rate of sausages. A large number of sausages will have surface scratches and ruptures during cutting, which affects the appearance and quality of the products. At the same time, the high breakage rate also means more waste of raw materials, which reduces the yield, thereby increasing the production cost and reducing the economic benefit and market competitiveness of the enterprise.

The transmission end of the conveying line 1 is provided with a lifting guide mechanism 6, which is used to lift the full load hanging rod transmitted to the end of the conveying line 1 and guide it into the supporting assembly 5. After being guided into the supporting assembly 5, the axis direction of the full load hanging rod is arranged transversely. The transverse displacement driving mechanism 3 is used to drive the supporting assembly 5 to move transversely. The cutting mechanism 4 is used to cut the connection of the sausage string along the axis direction when the full load hanging rod moves with the supporting assembly 5. After the hanging rod moves transversely to the preset position, the empty rod recycling device 2 is used to clamp and recycle the hanging rod. The traditional method of directly cutting the whole continuous sausage string causes high sausage breakage rate due to uneven swinging and stress. In the present equipment, the sausage string is hung on the hanging rod in a spiral manner, and the sausage is pre-divided into small units of two sausages. When entering the sausage cutting machine, the length of the sausage string is shortened, the stress is uniform, the swinging amplitude is reduced, the breakage rate is significantly reduced, the product appearance and quality are improved, the pre-cutting and separating reduce the breakage, reduce the raw material waste, improve the yield, thereby reducing the production cost, improving the economic benefit and market competitiveness of the enterprise, the equipment automatically completes the pre-cutting and separating of the sausage string, the operation is simple, the skill requirement for the operator is reduced, the human error is reduced, the production efficiency is improved, and the subsequent processing process is simplified, which is convenient for collaborative work with other equipment.

The symmetrical design ensures the balance of the hanging rod in the transmission process, avoids the inclination and skew of the hanging rod due to uneven stress, thereby ensuring that the sausage string can be stably transmitted to the end, providing a good starting position and posture for the subsequent cutting process. The rack 1 is further provided with a drop hopper 13 at the rear of the transmission chain 12. The sausage small units after cutting and separating can be timely and accurately dropped into the drop hopper 13 for collection, which is convenient for the unified treatment and transfer of the cut sausages, and avoids the scattering of materials around the equipment.
