Abstract
The utility model discloses a lifting device of a water box of PVC (polyvinyl chloride) thermal contraction film equipment. The lifting device is arranged right below the water box and comprises an upgrade base and a upgrade platform, wherein four corners of the upgrade base are respectively provided with worm and gear lifting screw rods; the upgrade platform is arranged above the worm and gear lifting screw rods and is parallel with the upgrade base, two symmetrical diverters are arranged among the worm and gear lifting screw rods, a diverter is also arranged on the middle of the two symmetrical diverters, and the three diverters can form a straight line; one side of the middle diverter is provided with a motor, and couplers are connected between the worm and gear lifting screw rods and the diverters as well as between the two diverters. The lifting device disclosed by the utility model has the advantages that the lifting of the water box is different from the traditional three traction liftings, and aims to overcoming the defect that a cooling effect is influenced because of air leakage in film bubbles and bad contact with a cooling water jacket.
Description
Technical field
The utility model relates to the device of producing for PVC heat shrink films, is specifically related to a kind of water tank lowering or hoisting gear of PVC heat shrink films equipment.
Background technology
PVC(polyvinyl chloride) heat shrink films is mainly used in printing and makes the bottle mark of all kinds of bottled drinks.
PVC heat shrink films is mainly manufactured by secondary inflation method at present.Production equipment used is mainly the upper traction of die head rotation jacking equipment as shown in Figure 1, or the upper traction of die head rotation lifting rotation equipment
The upper traction of die head rotation jacking equipment in process of production, due to the homogeneity error of die head mouth die clearance homogeneity error, cooling vane air quantity and link all can the cause film such as water jacket is cooling laterally the became uneven of (film bubble circumferencial direction) is even, so just on telolemma volume, form " quick-fried muscle ".Once occur in " quick-fried muscle ", the gently lower road of impact printing process is heavy become waste product.In above-mentioned production process, for eliminating horizontal became uneven, die head rotates in process of production all the time, and it is upper that the thickness point that mouth die clearance homogeneity error can be produced is like this distributed in film volume, and this measure is only worked in a film bubble.But it is upper that the thickness point of final finished (secondary film bubble) can not minute be distributed on film volume, so cannot eliminate " quick-fried muscle ".
The upper traction of die head rotation lifting rotation equipment is owing to having adopted traction rotating lifting gear in secondary film bubble, can eliminate " quick-fried muscle ", but second traction is at rotation and lifting, structure just compares bulky complex, weight is larger, easily produces the creeping phenomenon of mechanical movement during rotation, causes rotation not steady, affect the stability of film bubble, and cause the generation of the unstable or substandard products waste product of end product quality.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of water tank lowering or hoisting gear of PVC heat shrink films equipment is provided.In die head rotation, draw in slewing, adopt water tank lowering or hoisting gear to guarantee that in secondary film bubble, gas is full, will draw rotation separation with lifting, alleviate the weight that traction is rotated, make to rotate and lifting more steady.
For achieving the above object, the water tank lowering or hoisting gear of the designed a kind of PVC heat shrink films equipment of the utility model, this device is arranged under water tank, this device comprises upgrading base and upgrading platform, four jiaos of described upgrading bases are respectively arranged with worm and gear elevating screw, worm and gear elevating screw top is provided with the upgrading platform that is parallel to the base of upgrading, between described worm and gear elevating screw, be provided with two symmetrical steering gears, two symmetrical steering gear middles are also provided with a steering gear, and three steering gears are in alignment; Middle steering gear one side is provided with motor; Between described worm and gear elevating screw and steering gear, be connected with shaft coupling between two steering gears.
Further, four jiaos of described upgrading bases are respectively arranged with feet.
The beneficial effects of the utility model:
Water tank lifting of the present utility model is different from three traditional traction liftings, and object is to affect cooling effect in order to make up the gas leakage of film bubble internal cause with cooling jacket loose contact.

Fig. 2 is the top view of water tank lowering or hoisting gear;
In figure: 1. upgrading base, 2. upgrading platform, 3. worm and gear elevating screw, 4. steering gear, 5. motor, 6. shaft coupling, 7. feet, 8. water tank.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art understand.
As shown in Fig. 1～2: a kind of water tank lowering or hoisting gear of PVC heat shrink films equipment, this device is arranged under water tank, this device comprises upgrading base 1 and upgrading platform 2,1 four jiaos of bases of upgrading are respectively arranged with worm and gear elevating screw 3, worm and gear elevating screw 3 tops are provided with the upgrading platform 2 that is parallel to the base 1 of upgrading, between worm and gear elevating screw 3, be provided with two symmetrical steering gears 4, it is in alignment that two symmetrical steering gear 4 middles are also provided with 4, three steering gears 4 of a steering gear; Middle steering gear 4 one sides are provided with motor 5; Between worm and gear elevating screw 3 and steering gear 4, be connected with shaft coupling 6 between two steering gears 4.1 four jiaos of bases of upgrading are respectively arranged with feet 7.
Other unspecified part is prior art.Although above-described embodiment has been made detailed description to the utility model; but it is only the utility model part embodiment; rather than whole embodiment; people can also obtain other embodiment according to the present embodiment under without creative prerequisite, and these embodiment belong to the utility model protection domain.
