Description

Technical Field

[0001] The utility model belongs to the technical field of reconstituted tobacco production, and specifically relates to a low-energy self-cleaning and blowing device of a papermaking method reconstituted tobacco finished product boxing and bundling machine. Background Art

[0002] Papermaking process reconstituted tobacco, commonly known as tobacco flakes, uses tobacco waste such as tobacco stems, cigarette scraps and fragments as the main raw materials. The tobacco raw materials are soaked in water, and then the water-soluble and insoluble substances in the tobacco are separated into solid and liquid. With the help of papermaking equipment and technology, the tobacco fibers and other insoluble substances are dispersed in water and then made into a fiber sheet base through a papermaking machine. At the same time, the water-soluble substances are concentrated and then coated back on the sheet base. After drying, it becomes papermaking process reconstituted tobacco.

[0003] In the production process of papermaking reconstituted tobacco, finished product packaging is the last step in the production process, which plays a vital role in the quality of product packaging and production continuity. The packaging uses a side frame type automatic unmanned strapping machine, which controls the movement of mechanical parts through the turret spring control mechanism, cooperates with electronic equipment detection and motor operation, and performs actions such as cutting, gluing, feeding and receiving the strapping belt, and bundles and packages each finished reconstituted tobacco leaf. Each strapping process straps one belt at a time, and each box is strapped with four straps. During a strapping process, cutting, bonding, feeding and receiving of tapes occur. The plastic dust particles generated in this process adhere to the mechanical parts of the strapping machine, such as the top knife, cutter, feeding and receiving of tapes, and turret cam. They follow the mechanical parts into their strip frame parts or follow the mechanical movement during the next strapping process, blocking the reasonable gap between the moving parts or wearing the above-mentioned mechanism, causing abnormal friction between the moving parts of the above-mentioned mechanism. The mechanism controlled by the turret spring cannot return to its position on time or gets stuck, disrupting the designed movement amplitude and order of the moving parts in the equipment structure, causing the operation of the various parts of the strapping machine to be chaotic, until they cannot work normally and cannot strap the finished boxes normally. It will also cause the premature wear of the equipment's cutter, top knife, feeding belt and other mechanical parts, and the replacement of such parts will increase the maintenance cost. Failures caused by the above reasons will also cause production to stop, and the strapping machine equipment will be handled for maintenance and adjustment, affecting the continuity of the production and operation of reconstituted tobacco leaves. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the utility model provides a low-energy self-cleaning and blowing device for a papermaking method reconstituted tobacco finished product boxing and bundling machine that is independent of the equipment. The device reasonably uses the remaining space in the bundling machine equipment box for installation, and does not affect the operation of the internal components of the equipment. The device is used to automatically clean the bundling machine's cutter, top knife, belt feeding and receiving, turret cam and other mechanism components through compressed air, remove impurities such as plastic dust particles of the bundling belt generated during the operation of the bundling machine, ensure the cleanliness of the above components and prevent them from premature wear and blocking of reasonable gaps to cause abnormal friction between moving parts, thereby ensuring the normal operation of the bundling machine and the frequent and abnormal replacement of spare parts.

[0006] A low-energy self-cleaning and blowing device for a papermaking method reconstituted tobacco finished product packing and bundling machine, comprising a frame and a base, wherein the bottom of the frame is fixed to the base, and a plurality of cross clamps are arranged on the frame from top to bottom, wherein a trigger bracket is clamped on one of the cross clamps, and the trigger bracket is a hollow tube, one end of the trigger bracket is connected to a compressed air source, and the other end of the trigger bracket is closed and provided with a connecting plate, the connecting plate is fixedly connected to a normally closed mechanical valve, an air outlet is arranged in the middle of the trigger bracket, the air outlet of the trigger bracket is connected to the air inlet of the normally closed mechanical valve through a compressed air hose, and blow pipes are clamped on other cross clamps, and the air outlet of the normally closed mechanical valve is connected to the air inlet of each blow pipe through a compressed air hose and a joint, and a nozzle is arranged at the air outlet of the blow pipe.

[0007] Furthermore, compressed air quick connectors are provided at the air inlet and outlet of the trigger bracket, the air inlet and outlet of the normally closed mechanical valve, and the air inlet of each blowpipe.

[0008] Furthermore, the nozzle is a flat fan-shaped nozzle.

[0009] Further, the inner diameters of the trigger bracket, the blowpipe and the compressed air hose are the same.

[0010] Furthermore, a fixing hole is provided on the base.

The nozzle 11 is a flat fan-shaped nozzle. The trigger bracket 5, the blowpipe 1 and the compressed air hose 7 have the same inner diameter. The base 6 is provided with a fixing hole 61.

[0020] When in use, the switch of the normally closed mechanical valve 3 is connected to the cutter support 12 of the strapping machine so that the farthest end of the horizontal plane working moving route of the cutter of the strapping machine is the triggering position. The height of the frame 4 is h=670mm.

[0021] The utility model mainly uses compressed air as energy consumption, and intermittently uses compressed air to automatically clean the cutter, top knife, belt feeding and receiving, turret cam and other mechanism components.
