Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food production, in particular to a conveying device for food production. BACKGROUND

[0002] At present, when the existing food such as taro cheese ball is produced, the taro (or Liupu taro) is first washed, cut into pieces, and placed in a steamer together with purple sweet potato (if used) to be cooked. After being cooked, the skin is peeled off, and the taro (and purple sweet potato) is mashed into a paste. The right amount of purple sweet potato powder, fine sugar (or zero-calorie sugar), milk (or light cream) and butter (if used) are added to the taro paste and mixed evenly until the taro paste becomes smooth and creamy. The cream cheese is cut into small pieces or formed into small balls. The prepared taro paste is divided into several small doses, each about 50 grams. Flatten the small doses, wrap a piece of cheese inside, then pinch the opening tightly and form into a round ball. Make sure the cheese is completely wrapped inside the taro paste. Wrap the wrapped taro cheese ball with plastic wrap, then put it into a packaging box and label it in turn to obtain the taro cheese ball.

[0003] When the taro cheese ball is completed, it needs to be transported to the packaging area. When the taro cheese ball is transported to the packaging area, a roll of plastic wrap is provided outside the conveying device, and a cutting knife is installed near the conveying device. At this time, a worker pulls the plastic wrap and presses it down, so that the cutting knife cuts the plastic wrap. At the same time, another worker places the taro cheese ball on the cutting plastic wrap above the conveying belt, and then the taro cheese ball moves with the conveying belt to the packaging area. The worker wraps the plastic wrap around the taro cheese ball to realize packaging and boxing of the taro cheese ball.

[0004] However, during the transportation of the taro cheese ball with the cutting plastic wrap, it is manually assisted, and when the plastic wrap is attached to the conveying belt, the plastic wrap can move synchronously with the conveying belt. However, when the taro cheese ball is placed on the plastic wrap during transportation, it cannot be guaranteed that the taro cheese ball is located at the center of the plastic wrap. Often, the cheese ball is located at the edge of the plastic wrap, which requires the subsequent worker to constantly adjust the plastic wrap for packaging the cheese ball, thereby affecting the packaging progress of the cheese ball by the subsequent worker. Therefore, we propose a conveying device for food production. SUMMARY
