Description

Injection mouldr for internal pad of crown bottle-top

The utility model relates to a kind of machine of making bottle cap, relates in particular to pad injection moulding machine in a kind of crown cork.

At present, the production equipment major part of injection moulding crown cork is external import production line, a small amount of is the Italian inlet line of domestic imitation, the characteristics of these production lines are: adapt to and produce in enormous quantities, output investment ratio is bigger, production line of foreign country needs more than 400 ten thousand yuan of RMB, every on domestic imitation line also needs more than 200 ten thousand yuan of RMB, 1., the melt back of pad adhesive adopts the high-frequency induction heating mode in the crown plug, therefore needs a cover HF induction heating apparatus (needing 60,000 yuan of RMB approximately) design feature of this class production equipment has:.2., the traveller carrying magnetic in the compression moulding mechanism, bottle cap is located on traveller by magnetic force, traveller is operation from bottom to top in the sliding sleeve of compression moulding dish, with top fixing mould with the plastics extrusion modling in the bottle cap.3., the purpose of heat radiation when reaching preheating before the mold work and work by the water in mould circulation, thereby need a cover water circulation system.4., the crown plug after the moulding mainly goes out production line by wheel hand interlock rotation and belt driving band.By as can be seen above, its equipment complexity of existing production line, cost an arm and a leg, there is certain financial difficulty in medium and small enterprise when buying, so, along with the development of beer, beverage industry, it is comparatively simple that medium and small system lid enterprise presses for a kind of device structure, produces the less injection moulding crown plug production equipment of investment.

The purpose of this utility model just be based on above-mentioned condition and design a kind of simple and reasonable, the interior pad of the crown cork injection moulding machine that adapts to China's national situation, this equipment has been given up the very unnecessary servicing unit of some complexity, adopt simple parallel otherwise effective technique to improve, thereby equipment cost is greatly reduced.

The purpose of this utility model realizes by following measure:

The pad injection moulding machine mainly comprises frame in this crown cork, the plastics cutting and carrying device, by motor, the running part that mechanical transmissioning piece is formed, heater, by the feeding slideway, shift fork, the feed mechanism that receiver is formed, and compression moulding mechanism etc. is several most ofly constitutes, wherein, a, compression moulding mechanism is by cam disc, care feed tray and be arranged on cam disc, positioning disk between the care feed tray and backgauge dish are formed, be evenly equipped with a plurality of compression tools vertically at positioning disk and backgauge dish circumferential edges, on each compression tool, all be set with spring, circumferential edges at care feed tray is processed with a plurality of uniform its quantity U-shaped grooves identical with compression tool, its position is corresponding with the position of compression tool, is provided with a pneumatic material mouth that blows above care feed tray; B, care feed tray, positioning disk and backgauge dish are installed on the same turning cylinder, rotate with motor by transmission mechanism; C, receiver rotate synchronously by gear and compression moulding mechanism, and the circumferential edges of receiver offers a plurality of equally distributed open slots, are provided with a pallet that has a breach in the bottom of receiver; D, plastics cutting and carrying device are by gear (7) (20) and receiver run-in synchronism; E, shift fork rotate with receiver by bevel gear.

In the utility model, heater can adopt the heating wire heating also can adopt the infrared radiation component heating, to reduce equipment cost; Chassis in the heater is the pallet of receiver bottom; Turning cylinder rotates with motor by turbine worm.

The advantage that the utility model is compared with prior art possessed is: (one), because in this equipment, the melt back of crown plug inner binder is not to adopt high-frequency induction heating, but adopt resistance wire energising heating or infrared radiation heating, its effect is a simplified structure, reduced cost, HF induction heating apparatus needs 60,000 yuan of RMB approximately, and resistance wire energising heating or infrared radiation heater only need RMB less than 200 yuan.(2), adopt cam structure, mould and traveller join together, operation from top to bottom, the plastics extrusion modling in care feed tray will cover, lid leans on the groove on the pallet to locate, its effect is a simplified structure, reduces cost.(3), because the utility model when work rotating speed is not high, therefore given up water circulation system, the preheating before the equipment work realizes that by heating wire or infrared components heating mould has further been simplified device structure by the naturally heat radiation during work, reduces cost.(4), the bottle cap after the moulding promotes to send to change pneumatic blowing out into by original machinery, simplified operation.In a word, this compact equipment, simple and practical, given up the very unnecessary servicing unit of some complexity, adopt simple parallel otherwise effective technique to improve, thereby equipment cost is greatly reduced.The pad injection moulding machine adapts to China's national situation in this crown cork, can satisfy the needs of medium and small batch process, and for example: use this machine class to produce 80,000 of bottle caps, equipment investment only needs 60,000 yuan of RMB.
