Description

Technical Field

[0001] This utility model belongs to the field of magnetic material production technology, specifically relating to a device for cutting packaging bags. Background Technology

[0002] Materials that can respond to a magnetic field in a certain way are called magnetic materials. Based on the strength of their magnetism in an external magnetic field, materials can be classified into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and their response to external magnetic fields is relatively weak. Ferromagnetic and ferrimagnetic materials are strongly magnetic materials; the term "magnetic material" usually refers to strongly magnetic materials. For magnetic materials, magnetization curves and hysteresis loops are characteristic curves reflecting their fundamental magnetic properties. Ferromagnetic materials are generally composed of Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds. Magnetic materials are generally classified into soft magnetic materials and hard magnetic materials according to their ease of magnetization.

[0003] Chinese Patent Application No. 202510222992.0 discloses a closed-loop material bag-breaking and feeding device, comprising a conveying cylinder assembly and a bag-breaking cylinder assembly. The conveying cylinder assembly has a conveying cylinder body, which is hinged to a clamping sealing cover. The clamping sealing cover consists of two semi-circular covers, each with an anti-slip sealing strip on its opening and closing sides. An upper breather is provided on the clamping sealing cover. Several support rods are radially arranged at the bottom of the conveying cylinder body, and a sealing ring is provided on the outer wall of the conveying cylinder body. The bag-breaking cylinder assembly has a bag-breaking cylinder body, with a shaft seat at its center. A bag-breaking cone is provided on the shaft seat, and the bag-breaking cone has a cone rod and several cutters. A lower breather is provided on the outer wall of the bag-breaking cylinder body. The conveying cylinder body is inserted into the bag-breaking cylinder body, and the conveying cylinder body is sealed to the bag-breaking cylinder body through the sealing ring. This invention allows bag-breaking and feeding to be carried out in a closed and breathable space, preventing dust leakage, providing a healthy working environment, reducing feeding losses, and improving feeding efficiency.

[0004] Chinese patent application number 202421739642.9 discloses a semi-automatic feeding station. A ton bag is transported through a material flow port above a dustproof device to an unpacking device. A clamping device is activated to clamp the bag opening. Then, through an operating port on the side of the dustproof device, the bag opening at the sealing line is cut open. The bag opening is manually placed onto the unpacking cylinder. A lifting mechanism lowers the pressure plate until the pressure plate and unpacking cylinder tightly press the bag opening. The clamping device is then released, allowing the material inside the ton bag to be released and discharged from the semi-automatic feeding station through the material discharge channel on the pressure plate and unpacking cylinder. The control system controls the lifting mechanism to move the ton bag through the material discharge channel on the pressure plate onto the unpacking cylinder, controls the clamping device to clamp the bag opening, and controls the flow-assisting beater to beat the ton bag to reduce material residue. The dustproof device prevents dust spillage, thus effectively ensuring the accuracy and safety of the feeding process.

[0005] In the production process of magnetic materials, raw materials are mainly packaged in bags. Currently, most of these bags are opened manually, which results in high labor intensity and low work efficiency for workers. Although the aforementioned patent discloses a device for opening bags, it has the problems of complex structure and high cost of use, and is therefore not suitable for opening magnetic material packaging bags.

[0006] Therefore, there is an urgent need for a device for cutting packaging bags, which has the characteristics of simple structure, low operating cost and continuous opening of packaging bags. Utility Model Content

[0007] The purpose of this invention is to provide a device for cutting packaging bags, thereby solving the problems mentioned in the background section. The device for cutting packaging bags provided by this invention has the characteristics of simple structure, low operating cost, and the ability to continuously open packaging bags.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a device for cutting packaging bags, comprising a frame, a conveyor belt mounted above the frame, an mounting frame mounted above the conveyor belt, a pressing component mounted on the mounting frame, an opening component for cutting open the packaging bag mounted on the pressing component, a hopper for separating the material from the packaging bag provided below the discharge end of the conveyor belt, and a collection box provided below the hopper.

[0009] To achieve automatic opening of the packaging bags, the opening assembly further includes a mounting base, on which an opening motor is mounted, and an opening blade is mounted on the output end of the opening motor. The opening blade has a serrated structure on its circumference.

[0010] To facilitate the height adjustment of the opening component and ensure that the opening blade can cut open the packaging bag, the mounting base is further provided with at least two vertically distributed waist grooves.

[0011] To further separate the materials from the packaging bags, a partition plate is connected to the upper part of the hopper, and the partition plate has dense mesh.

[0012] To drive the hopper to vibrate and allow the material inside the packaging bag to fall out as much as possible, a vibrator is further installed on the side of the hopper.

[0013] To ensure the packaging bag doesn't shift when the opening blade cuts it open, thus guaranteeing successful slicing, the pressing assembly further includes a profile connected to a mounting frame via a connecting seat. A driven wheel is mounted at one end of the profile, and a driving wheel is mounted at the other end. The driving and driven wheels are connected by a conveyor belt. The pressing assembly also includes a motor mounted on the mounting frame. A drive wheel is connected to one side of the drive wheel, and a synchronous pulley is mounted on the motor's output end.

[0014] To further guide the packaging bags containing materials, a side guard assembly is provided above the conveyor belt. The side guard assembly includes two opposing side guard bodies, which are mounted above the conveyor belt by at least two side guard seats.

[0015] In order to adjust the distance between the two edge-blocking bodies to accommodate packaging bags of different sizes, the edge-blocking bodies are further connected to the edge-blocking seat via an adjusting rod. The adjusting rod and the edge-blocking seat are slidably connected, and the edge-blocking seat is threaded with an adjusting screw whose end abuts against the adjusting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model is equipped with a conveyor belt, a bag opening component, and a hopper. The upper end of the hopper is connected to a partition plate with dense mesh. The conveyor belt transports the packaging bag containing magnetic material.
