Embodiment 1

[0016] The structure of this embodiment is as figure 1 and figure 2 As shown, the automatic bag unpacking machine of the present invention has four sections of conveyor belts S1, S2, S3, S4. The first section of conveyor belt S1 is used to convey material bags, and an anti-skid baffle 2 is also arranged on this section of the conveyor belt, and its main function is to prevent the frozen material bags from sliding down during the feeding process. The anti-skid baffle is fixed on the conveyor belt S1 and moves together with the conveyor belt, and the distance between the front and rear plates of the anti-skid baffle is greater than the length of the bag.

[0017] The top of the second section conveyor belt S2 is provided with a solid bag expansion and contraction platen 7, which relies on the driving of the hydraulic cylinder to realize the fixed bag effect of the bag breaking process. The front end of the conveyor belt S2 is provided with a bag breaking cutter 8, which can m...

Embodiment 2

[0021] The structure of this embodiment is as image 3 and Figure 4 As shown, the automatic bag unpacking machine has three sections of conveyor belts S1', S2', S3'. The first section of conveyor belt S1' is used for conveying material bags, and an automatic feeding device is arranged in front of the conveyor belt. An anti-skid baffle 4' is also installed above the conveyor belt S1' to prevent the frozen material bags from slipping off the conveyor belt during material conveyance. The automatic feeding device consists of a push plate 1', a moving guide rail 2' and limit switches L1' and L2' installed at the two ends of the moving guide rail. The frozen material can be pushed onto the first conveyor belt S1' by the push plate 1' moving on the guide rail 2'.

[0022] The left and right sides of the second section conveyor belt S2' are equipped with solid bag expansion and contraction platens 6' and 7' running oppositely, which can be fixed on the conveyor belt when the froze...

Abstract

The invention discloses an automatic bag opening machine. The automatic bag opening machine comprises a conveyer belt, a bag breaking tool, a bag grabbing device, a fixing device, a material processing channel and a packaging bag recycling bin, wherein the conveyer belt runs in a section manner and is at least divided into three sections, the first section of the conveyer belt is used for conveying material bags, the second section of the conveyer belt is matched with the bag breaking tool to cut the material bags, and the third section of the conveyer belt is matched with the bag grabbing device to achieve separation of the materials and the packaging bags; the bag breaking tool, the bag grabbing device and other movement parts can move on respective movement guide rails, and limit switches are arranged at two ends of each movement guide rail for preventing the parts from moving over the limiting position; photoelectric sensors are arranged at the end of the second section of the conveyer belt, the end of third section of the conveyer belt and the movement guide rail on the material processing channel. The automatic bag opening machine can separate bagged frozen raw materials from bags, and can alleviate labor intensity of workers, improve the working efficiency, reduce the manual bag opening expense, improve the automation production degree of fish meal and achieve the purpose of reasonably recycling the waste bags.

Description

technical field [0001] The invention relates to the field of bag unpacking equipment, in particular to an automatic bag unpacking machine. Background technique [0002] Fishmeal is a powdery food material processed from fish, shrimp, crab and other aquatic products or fish heads, tails, leftovers and viscera obtained from fish processing. The fresh raw materials for processing fishmeal need to be frozen and kept fresh after they are bagged and packaged, which will lead to the difficulty of disassembling the frozen packaging bags when processing fishmeal. At present, the unpacking work before processing fishmeal is mainly done manually, which is time-consuming and labor-intensive, and the labor cost for unpacking is high. Taking a medium-sized fishmeal manufacturer in Weihai Shidao as an example, the annual raw material requirement is 2.8 million tons, and a bag of raw materials weighs about 15 kilograms, while the number of manual unpacking is 186 million per year, and the ...
