Technical Field

The invention relates to the technical field of bag breaking devices, in particular to a pneumatic bag breaking device.

Background

In the garbage recycling device, the garbage bag needs to be crushed to recycle the garbage in the bag. At present, the technical schemes of roller type bag breaking, reamer bag breaking and the like exist.

The existing bag breaking technology generally has the problem that fragments are mixed into garbage after the garbage bag is broken, and for a garbage classification system based on a visual recognition technology, the fragments of the garbage bag mixed with the garbage can influence recognition, so that the breaking scheme is not suitable for the situation. Aiming at the problem that the garbage bag cannot be independently recycled after being broken, the garbage bag can be rolled up more completely by adopting a double-column winding scheme, so that the garbage bag is prevented from being mixed into garbage after being broken; the defect is obvious, the garbage bags are wound and screwed together in the bag breaking process, the strength is increased, and the bag breaking equipment is damaged.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a pneumatic bag breaking device for breaking and recycling plastic garbage bags.

The technical scheme of the invention is as follows: a pneumatic bag breaking device comprises a first moving mechanism, a second moving mechanism and a multi-shaft pneumatic bag breaking mechanism, wherein the first moving mechanism and the second moving mechanism are vertical to each other; the multi-shaft bag breaking mechanism comprises a structural plate, a high-pressure gas nozzle and at least three sets of bag breaking assemblies are mounted on the structural plate, each set of bag breaking assembly comprises a main drive, an auxiliary drive and a bag breaking drill, and a blade capable of moving up and down in a reciprocating mode is arranged in the bag breaking drill. The first moving mechanism and the multi-shaft pneumatic bag breaking mechanism are located on the second moving mechanism, the first moving mechanism and the second moving mechanism act together to locate the multi-shaft pneumatic bag breaking mechanism, the bag breaking drill winds and tensions the garbage bag, the high-pressure gas nozzle sprays high-pressure gas to puncture and tear the garbage bag, and the circular blade cuts the garbage bag wound on the bag breaking drill to enable the garbage bag to slide down.

The structural slab comprises an upper structural slab and a lower structural slab, a main drive and an auxiliary drive are installed on the upper structural slab, and a high-pressure gas nozzle and a bag breaking drill are installed on the lower structural slab. Wherein, main drive and auxiliary drive all adopt the motor, and the output shaft of motor is towards structural slab down.

The bag breaking drill is a hollow cylinder with a through groove in the middle and external threads at the lower part, the through groove penetrates through the circumferential side face of the bag breaking drill along the diameter of the bag breaking drill, a circular blade and a screw rod are arranged in the through groove, and a threaded hole matched with the screw rod is formed in the middle of the blade. The movable range of the blade is restricted within the length range of the bag breaking drill, the cutting edge of the circular blade extends out of the through groove of the bag breaking drill, and the circular blade is used for cutting the garbage bag once or in a reciprocating mode.

The upper part of the screw is connected with the output end of the auxiliary drive through a one-way bearing, and the bag breaking drill is connected with the output end of the main drive through a transmission assembly. The main drive drives the belt breaking drill to rotate, the transmission assembly can adopt a reduction gear set or a chain wheel transmission set, and the auxiliary drive drives the screw rod to rotate in a one-way mode, so that the blade is driven to move up and down in a reciprocating mode.

The high-pressure gas nozzle is provided with a spring and is connected with the gas guide pipe, and the upper structural plate is provided with a gas circuit mounting hole site for penetrating the gas guide pipe. The high-pressure gas nozzle can stretch and bend within a certain range, and the position of the gas path mounting hole corresponds to the position of the high-pressure gas nozzle.

The first moving mechanism adopts a vertical sliding rail, and the second moving mechanism adopts a horizontal sliding rail. Wherein, the horizontal slide rail is connected with the vertical slide rail, and the multi-shaft bag breaking mechanism can move on the vertical slide rail. The driving mode on the vertical slide rail and the horizontal slide rail can adopt a transmission belt transmission or a screw transmission which is commonly used by the technical personnel in the field.

The upper structural plate is also provided with a camera and a sensor. The upper structural plate is reserved with a camera and a sensor mounting position, and the multi-shaft pneumatic bag breaking mechanism can be positioned in an auxiliary mode through vision or a sensor.

The bag breaking assemblies are arranged in three sets, and the three sets of bag breaking assemblies are arranged in an equilateral triangle.

The upper structural plate and the lower structural plate are both equilateral triangles in shape and same in size, and the three bag breaking drills are respectively positioned at three corners of the lower structural plate.

The high-pressure gas nozzles are four, three of the high-pressure gas nozzles are arranged in an equilateral triangle, and the other high-pressure gas nozzle is positioned in the center of the equilateral triangle. The three angles of the triangle formed by the high-pressure gas nozzle are respectively positioned in the central positions of the three sides of the lower structural plate, and the garbage bag can be effectively broken and torn by adopting the structure.

The use principle of the pneumatic bag breaking device is that the second moving mechanism moves the multi-shaft pneumatic bag breaking mechanism to the position above bagged garbage, the bag breaking unit descends along the first moving mechanism, the three main drives drive the three bag breaking drills to rotate, the garbage bag is wound on the three bag breaking drills, and the garbage bag rotates along with the belt breaking drill and is gradually tensioned to form a triangle. High-pressure gas is rapidly sprayed out from the four high-pressure gas nozzles to puncture the garbage bag to cause punching and tearing of the garbage bag, and the three bag-breaking drills tear and wind the garbage bag. The first moving mechanism and the second moving mechanism move the multi-shaft gas bag breaking mechanism away, the auxiliary drive drives the screw to rotate, the circular blade in the bag breaking drill descends, the garbage bag is cut and made to slide down from the bag breaking drill, and then bag breaking and cleaning are completed. Because the screw rod is connected with the auxiliary drive through the one-way bearing, the blade cannot fall in the rotating process of the bag breaking drill, after cutting is finished, the auxiliary drive rotates at a low speed, the main drive rotates reversely and quickly, and the circular blade rises to return to the initial position.

Compared with the prior art, the invention has the following beneficial effects:

the pneumatic bag breaking device can completely remove the garbage bag and leave garbage; adopt the pneumatic broken bag mode of triaxial, open into triangle-shaped with the disposal bag, the supplementary broken bag of reuse high-pressure gas, realize broken bag and recovery process with the blade cutting at last, overcome the difficult problem of tearing of the broken bag of unipolar, overcome the problem that the broken bag of biax twines the broken bag of damage bores and the axis body, circular blade can reciprocate the reciprocal cutting, this device reliability is high, avoids the disposal bag piece to sneak into rubbish, broken bag is efficient, and is fast and effectual.
