In recent years, a variety of fully automatic bag unpacking machines have appeared, such as spiral bag breaking machines, multi-knife bag unpacking machines, saw blade bag unpacking machines, and disc blade bag unpacking machines. The unpacking mechanism of these unpacking machines is fixed on the periphery of the conveyor belt. When the bag is running forward on the conveyor belt, the cutting component is cut along the direction of the conveyor belt, and then the material and the bag are separated by the unloading mechanism. Such bags cannot be reused because they are shredded or cut sideways, resulting in a lot of waste.

Utility model content

The purpose of this utility model is to solve the above-mentioned deficiencies, thereby providing an unpacking machine capable of fully automatic unpacking, unloading, and bag collection. The unpacking machine has the advantages of high efficiency, simple operation, reusable bags and is suitable for unpacking bags of various specifications.

In order to achieve the above purpose, the technical solution of the utility model is: an unpacking machine, which includes a conveying mechanism, an unpacking mechanism and a discharge mechanism; the conveying mechanism has a conveyor belt, the unpacking mechanism has a set of cutting components, the unloading The mechanism has a set of inserts and bag pressing wheels, which are used to insert the bag and lift the bag for discharge. The bag pressing wheel includes active bag pressing wheels and passive bag pressing wheels; the cutting assembly includes blades, driving A motor for rotating the blade and a swing arm for driving the blade to complete the cutting movement; the blade is driven by the swing arm to rotate above the conveyor belt to cut the front side of the forward direction of the bag.

Both sides of the conveyor belt are provided with guide plates fixed on the guard plate brackets, and the width between the guide plates can be adjusted to be suitable for packaging bags of various specifications to ensure that the bags pass through the set position accurately.

The unpacking mechanism also includes at least one travel switch to control the movement of the bag; the travel switch adopts a photoelectric switch or a pressure switch, and when the bag moves to the set position, the travel switch is triggered to make the cutting assembly complete the cutting task And let the conveyor belt continue to convey the bag after the cutting is completed.

The cutting assembly includes at least one high-speed rotating blade, a motor, a swing arm, a swing arm cylinder and a support frame. The blade is rotated by the motor, and the support frame fixes the entire cutting assembly on the conveying mechanism, and the swing arm is driven by the swing arm cylinder or the motor to realize the horizontal cutting function of the cutting assembly.

The plug is arranged on the rotating shaft driven by the cylinder connecting rod or the motor, and the plug rotates between the discharge end of the conveying mechanism and the bag pressing wheel. When the bag is transported to the unloading mechanism, the plug is inserted into the bag cut in front along the direction of transport, and is driven by the cylinder connecting rod to rotate upward to lift the bag to separate the bag from the material, and then rotate to the bag pressing wheel on the collection bag.

As an improvement of the utility model, the unloading mechanism is connected with a spiral bag collector, and when the bags are taken out by the bag pressing wheel, they can be automatically collected and sorted by the spiral bag collector.

Through the utility model, the bag can be effectively recovered for secondary use, and meanwhile, it also has the advantages of high working efficiency, simple operation, and being applicable to packaging bags of various specifications.

Detailed ways

Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

As can be seen from the specific embodiment shown in Figures 1 to 3, the transmission mechanism includes a support frame 3, a conveyor belt 2, a motor 4 and a guide plate 5, the conveyor belt 2 is driven by the motor 4, and the guide plate 5 is fixed on both sides of the conveyor belt 2 , the width of the guide plate 5 can be adjusted to adapt to the situation of packaging bags of different specifications; the unpacking mechanism includes a blade 6, a swing arm 7, a motor 8, a swing arm cylinder 9 and a fixed frame 10, and the motor 8 drives the blade 6 to rotate at a high speed , the blade 6 is set on the swing arm 7, and the swing arm 7 performs repeated cutting motions driven by the swing arm cylinder 9; the unloading mechanism includes a plug 11, a passive bag pressing wheel 12, an active bag pressing wheel 13, and a bag pressing cylinder 14 , screw feeder 15 and cylinder connecting rod 16, plug 11 is located on the rotating shaft that is driven by cylinder connecting rod 16, and active bag pressing wheel 13 is driven to rotate by motor, and passive bag pressing wheel 12 links to each other with bag pressing cylinder 14, when The bag is lifted by the plug and sent to the driving wheel, the passive bag pressing wheel 12 falls down to compress the bag sheet, the rotating bag pressing wheel rolls out the bag, and sends it to the spiral bag collector 17 of the bag rolling mechanism to realize automatic The function of collecting bags.

The unpacking machine of the utility model operates in the following manner, the conveyor belt 2 transports the bag 1 to the set position, touches the travel switch, the swing arm cylinder 9 drives the swing arm 7 to make an arc movement, and the high-speed rotating blade 6 moves along the vertical direction The direction of the conveyor belt cuts the front of the bag; with the movement of the conveyor belt 2, the bag 1 is transported to the unloading mechanism, and the plug 11 of the unloading mechanism is aligned with the cut in the front of the bag at the end of the conveyor belt, and along the conveying path Insert it into the inside of the bag 1 that was cut in the front side; when the plug 11 is fully inserted into the inside of the bag 1, the cylinder connecting rod 16 drives the plug 11 to rotate upwards to lift the bag 1 to realize the separation of the bag 1 from the material in the bag and pour it out The material falls into the screw conveyor 15 and sent out; when the bag 1 is lifted by the inserter 11 and sent to the driving wheel bag pressing wheel 13, the bag pressing cylinder 14 will press the passive wheel bag pressing wheel 12 down until it is close to the driving bag pressing wheel 13, and the bag sheet is compressed, and the rotating bag pressing wheel takes out the bag 1; the empty bag 1 taken out is sent to the spiral bag collector 17 for automatic collection and arrangement.
