Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing and relates to weighing equipment and conveying equipment, specifically a production layout for an automatic food weighing and packaging processing device. Background Technology
[0002] In food processing plants, modified atmosphere packaging (MAP) machines are typically used to adjust the gas composition in food packaging to extend shelf life and maintain quality. For example, nitrogen is used for filling, followed by sealing and sterilization. This allows food to be stored at room temperature for several months without spoiling. To ensure uniform product specifications, food is first packaged into sealable containers according to specified weights before undergoing MAP. A single production line often processes various types of packaged products. For instance, in meat processing, fresh meat needs to be packaged before entering the MAP machine. However, because the weight of each piece of meat, bone, etc., varies during the cutting process, they must be weighed and then combined according to weight requirements before being packaged into bags to ensure a uniform total weight within each package. In existing technologies, cutting, weighing, and bagging all require multiple operators. After cutting, the meat is weighed by the weighing personnel and then bagged. Oversized or undersized pieces are returned to the cutting personnel. The weighing personnel fill a bag and place it on the conveyor belt, and then the next belt is loaded. The cutting personnel have to wait most of the time, resulting in low overall processing efficiency and a large number of personnel required, which is an unreasonable allocation.
[0003] Preliminary searches revealed the following publicly available technologies:
[0004] A food cutting and packaging system (CN119551265A) solves the problem of poor performance of existing food cutting and packaging devices. It includes a support base, with a conveying and cutting mechanism and a packaging bag supply mechanism located at one end of the top of the support base. The packaging bag supply mechanism is located at the bottom of the conveying and cutting mechanism. At the other end of the top of the support base, a packaging mechanism and a discharge conveyor belt are located. The packaging mechanism is located at the bottom of one end of the conveying and cutting mechanism, and the discharge conveyor belt is located at the bottom of the packaging mechanism. The conveying and cutting mechanism consists of a support frame, a combined alternating conveying assembly, a cutting assembly, a material collection conveying assembly, and a discharge hopper. This cutting and packaging system enables automatic conveying, cutting, and packaging of food, effectively improving work efficiency.
[0005] As can be seen from the comparison, the technical solution of this application is significantly different from the aforementioned prior art. Utility Model Content

The plate-slab area is equipped with multiple plate-slab worktables, and the output ends of the plate-slab area are connected to the input ends of the controlled atmosphere line.
[0011] Furthermore, the weighing and counterweighting area specifically includes a pre-weighing conveyor line, an electronic belt scale, a post-weighing conveyor line, metering bins, and a preparation robot. The front of the pre-weighing conveyor line is connected to a cutting table, and the rear of the pre-weighing conveyor line is connected to an electronic belt. The rear of the electronic belt scale is connected to the post-weighing conveyor line. Multiple metering bins are arranged side-by-side on both radial sides of the post-weighing conveyor line, and the movement of the metering bins is controlled by an automatic weighing and counterweighting system. A preparation robot is installed above the post-weighing conveyor line, which is used to place meat pieces from the post-weighing conveyor line into the metering bins. A lower counterweight conveyor line is arranged parallel to the post-weighing conveyor line, and the rear of the lower counterweight conveyor line is connected to a quantitative conveyor line. The lower counterweight conveyor line can receive meat pieces fed from the metering bins.
[0012] Furthermore, the lower counterweight conveyor line can transmit in both directions. The front end of the lower counterweight line is connected to the abnormal product return line, and the output end of the abnormal product return line is equipped with an abnormal product recycling box.
[0013] Furthermore, each of the metering boxes is connected to a tilting cylinder at the bottom.
[0014] Furthermore, the slitting table is equipped with a primary processing station and a secondary processing station, and a distribution conveyor line is provided between the primary processing station and the secondary processing station.
[0015] Furthermore, the quantitative conveying line is a loop, and a cleaning area is connected to one side of the quantitative conveying line. A tray cleaning line is installed in the cleaning area, which is located between the tray loading area and the weighing and counterweight area.
[0016] Furthermore, the input end of the slitting area can accommodate a mobile vehicle.
[0017] The advantages and positive effects of this utility model are:
[0018] 1. This device can be applied to various production lines.
