Abstract

The invention discloses a high-efficiency multifunctional label removing machine, relates to plastic machinery, and particularly relates to an auxiliary machine of a waste plastic bottle recycling production line, which realizes high-efficiency label removing of plastic bottles and effective separation of recycled materials and impurities. A motor drives a main shaft to rotate in a belt driving mode, a sawtooth-shaped stationary knife is arranged on the inner wall of a cylinder according to a spiral line, and a label removing tool with a structure shaped as a sharp eagle claw is arranged at a tooth peak of a rotary knife when the sawtooth-shaped rotary knife is arranged on the main shaft according to the spiral line; therefore, the surfaces of plastic bottles entering the cylinder are torn by a high-strength and high-density tearing force, and then label paper is easily dropped off from the bottle bodies. Holes with a certain specification are formed in the bottom of the cylinder, a large quantity of bottle caps which deform due to extrusion and even are torn to separate from the bottle bodies can be directly discharged from the holes. A fan provides strong air for sucking the label paper and the bottle caps in the materials in a label sucking box, the label paper and the bottle caps enter a label collecting bag, and the bottle bodies are blocked outside a screen and continuously go forwards under the drive of the main shaft so as to be discharged from a discharging hole.

Description

A kind of high-efficiency multi-function label removing machine

Technical field

The present invention relates to plastics machinery, especially relate to a kind of Aided Machine of clean and reuse production line of waste plastic bottle.

Background technology

In recent years, be accompanied by the growth of population in the world, the consumption figure of plastic bottle also increases greatly.In the face of the waste plastic bottle that sharply increases, reclaim industrialization, scale and mechanization that the waste or used plastics industry requires to advance the waste plastic bottle recovery urgently.For the plastic bottle that reclaims, will be first with the label on the bottle, the assorted material such as bottle cap is removed, just can carry out follow-up operation, and the label removing machine of commonly using at present is equipped with a lot of high-strength screws by the blade on the main shaft, screw scrapes off the label on the bottle in rotation, by water label is gone out screen cloth again, and plastic bottle is isolated in the screen cloth, realize separating of label and bottle, the mark rate of taking off of equipment is that the reset condition according to bottle determines that the mark rate of taking off of compression bottle is 60%～70%, the mark rate of taking off of non-compression bottle is 70%～80%, on the whole, taking off the mark rate and can only reaching 80% in the ideal situation of plastic bottle obviously can not be satisfied current production requirement.

Summary of the invention

The purpose of this invention is to provide a kind of much higher function label removing machine of mark rate that takes off.

The technical solution adopted for the present invention to solve the technical problems is: a motor drives the main shaft rotation by the mode with transmission, machine tube inner wall is by the helix zigzag dead knife of arranging, and when arranging the zigzag moving knife by helix on the main shaft, what be provided with the sharp claws of a hawk of structure likeness in form at the place, tooth peak of moving knife takes off the mark cutter, like this, the plastic bottle surface that enters machine barrel will be subject to high strength, the highdensity power of tearing effect, and label paper is easy to just split away off from body.Machine barrel bottom is provided with the hole of certain specification, and distortion even tear and a large amount of bottle caps of breaking away from bottle can directly be discharged by the hole is squeezed.Then, the tool driving bottle of arranging by helix, label paper and a small amount of bottle cap march to the label collecting region by helix, the label collecting region is positioned at the machine barrel back segment, by screen cloth, inhale standard packing box, the label collecting bag, blower fan, volume damper and butterfly valve and blower rack form, provide the suction standard packing box required air force by regulating butterfly valve and volume damper control blower fan, the high wind that blower fan is provided will suck the suction standard packing box and enter the label collecting bag through label paper and bottle cap in the material of label collecting region, at last, plastic bottle body is blocked in screen cloth to be continued to advance under the tool driving on the main shaft outward, discharge through discharging opening, enter the operation of next waste plastic bottle cleaning product line.

The invention has the beneficial effects as follows, compare with label removing machine commonly used at present, a kind of high-efficiency multi-function label removing machine has not only improved the mark rate of taking off of plastic bottle effectively, and (the mark rate of taking off of compression bottle is 92%～96%, the mark rate of taking off of non-compression bottle is 95%～98%), can also realize that to recovered material label paper, bottle cap separate automatically effectively---bottle and assorted material---, greatly reduced waste plastics cleaning bottle exhausting line postorder to the assortment of waste plastic bottle, the workload of cleaning, when saving cost, greatly improved the quality of recovered material.

Description of drawings

Below in conjunction with drawings and Examples this equipment is further specified.

Fig. 1 is the front view of this equipment.

Among the figure, 1. dc motor, 2. driving pulley, 3. frame, 4. classical V-belt, 5. passive belt wheel, 6. bearing block A, 7. feed hopper, 8. main shaft, 9. hex nut, 10. bolt, 11. dead knives, 12. moving knife, 13. moving knife seats, 14. machine barrels, 15. blower fan, 16. butterfly valves, 17. inhale standard packing box, 18. volume dampers, 19. bearing block B, 20. bottle caps and water outlet, 21.

The specific embodiment

As shown in drawings, 1, answer the procuratorial work foundation bolt whether to support steadily before starting, in order to avoid machine vibration during unlatching.

2, regulate the gap of moving knife (12) and dead knife (11) before the start by adjusting the position of moving knife (12) on moving knife seat (13) by user's request, compression bottle need be transferred to minimum, and non-compression bottle is transferred to maximum.Then procuratorial work dc motor (1) and blower fan (15) whether correctly turn to, need unloaded operation 3-5 minute of rotating after the start.

3, opening device, with belt conveyor or other conveying equipments waste plastic bottle is entered machine barrel (14) through charging aperture (7), at this moment, controlling blower fan (15) by the butterfly valve (16) on adjusting machine barrel (14) the back segment suction standard packing box (17) and volume damper (18) provides suction standard packing box (17) required air force, concrete regulating degree is seen the situation that plastic components separates and is decided, as long as substantially reach the label paper that does not come off in discharging opening (22) the bottle heap out, do not have bottle to get final product in the label collecting bag (24).

4, when needs are shut down, must stop first material loading, waited 3-5 minute, shut down again.

5, this machine can use separately, also can be connected in series in the production line and use.
