Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold noodle automatic production equipment, and particularly relates to a cold noodle automatic production line integrating cutting, weighing, folding and collecting. BACKGROUND

[0002] In the cold noodle production process, the dough belt extruded by the dough belt extruder is placed on the conveying belt of the cold noodle production equipment, and then the cold noodle production equipment cuts the dough belt into cold noodles of a set length. In order to reduce the length of the cold noodles for the convenience of packaging, storage and transportation, the cold noodle production equipment sets a folding mechanism to fold the cold noodles to form two layers of cold noodles, three layers of cold noodles 1 (as shown in Figure 1

[0003] In the process of folding the three layers of cold noodles 1, the existing cold noodle production equipment sets a first folding mechanism to control the rotation of three first folding pressure rods to fold the first end of the cold noodles, and sets a second folding mechanism to control the rotation of three second folding pressure rods to fold the second end of the cold noodles. Since the three folding pressure rods need a large space when rotating and folding, the first folding mechanism and the second folding mechanism need to occupy a large working space, which in turn causes the cold noodle production equipment to occupy a large working space, thereby reducing the utilization rate of the working space and increasing the production cost of the enterprise.

[0004] Moreover, the existing cold noodle production equipment does not set a related positioning mechanism to position the cold noodles at the folding position of the cold noodles during the folding process. Since the cold noodles are made of buckwheat, wheat and starch, the cold noodles are particularly tough, tough and hard due to the presence of starch. When the existing cold noodle production equipment folds the cold noodles, the folding position of the cold noodles is not positioned, which causes the folding position of the hard cold noodles to shift and move during folding, and even causes the cold noodles to deform, resulting in defective products, unstable folding work and thus affecting the production efficiency.

[0005] In addition, the existing cold noodle production equipment cuts the cold noodles into cold noodles of a set length after one end of the cold noodles is folded, and then weighs the cold noodles with one end folded. Since the folding position of the cold noodles shifts and moves during folding in the existing cold noodle production equipment, the weight of the cold noodles with one end folded deviates, which affects the weighing accuracy.
