Description
Technical field
The utility model relates to rolling equipment field, particularly the special flattening device of a kind of PVC film rolling machine.
Background technology
Calender is by two or more rollers, arranges by certain forms, at a certain temperature, rubber or plastics compacting extension is become to the film of certain thickness and surface configuration or the equipment of film.PVC film rolling machine is for the production of PVC calendered film, production process at PVC film is last, need to PVC film be entirely wound into coiled strip by winder, so before this, PVC film must entirely be unfolded, by the pulling force between conveyer belt and winder to the flattening of PVC film at present, film is flattened naturally, have randomness, effect is undesirable, effect to flattening PVC film is undesirable, so need a kind of technology make up this deficiency.
Prior art is compared, and the invention has the beneficial effects as follows:
1. in the utility model, the left side cylinder of roll shaft is provided with right-handed thread, on the cylinder of right side, is provided with left hand thread, when can making like this roll shaft motion, can make the film that is positioned at roll shaft below fully flatten;
2. in the utility model, the centre of roll shaft is provided with one section of smooth cylinder, so can reduce the difficulty of processing of roll shaft, is also in order fully to improve the effect that film flattens;
In the utility model base for supporting be shaped as a conical cylinder, for conical cylinder can strengthen and the contact area on ground, improve the stability of this device;
4. the utility model is simple and reasonable, ensures that rolling equipment production line is more smooth and easy, and cheap for manufacturing cost, is applicable to popularize on a large scale.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of PVC film rolling machine special flattening device, the special flattening device simple structure of this PVC film rolling machine, easy to use and cheap for manufacturing cost.
For solving the problems of the technologies described above the technical scheme that the utility model adopts be: the special flattening device of a kind of PVC film rolling machine, comprise roll shaft and support, its innovative point is: described roll shaft is cylindrical roll body, all be respectively equipped with a shaft shoulder at roll shaft two ends, the shaft shoulder be shaped as cylinder and roll shaft global formation; Described rack body is an optical axis, connects in any one end of optical axis
There is a base for supporting; The other end of described optical axis is provided with a back-up block, and back-up block is one
The cavity of rectangle is provided with a manhole in the middle of back-up block; Two shaft shoulders of roll shaft respectively with the back-up block inside of two supports is installed, and whole roll shaft can be realized 360 ° of rotations; The special flattening device of described PVC film rolling machine, is positioned at calender conveyer belt and winder centre position, and participates in the motion of calender ground.
Further the left side cylinder of described roll shaft is provided with right-handed thread, on the cylinder of right side, is provided with left hand thread.
The centre of further described roll shaft is provided with one section of smooth cylinder, and the length of smooth cylinder is 20cm.
The length of further described roll shaft is consistent with the length of conveyer belt roller.
Further described base for supporting be shaped as a conical cylinder, with support global formation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation between the utility model and calender conveyer belt and winder.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.The special flattening device of PVC film rolling machine, comprises roll shaft 1 and support 2.
As shown in Figure 1, the structure of the special flattening device of PVC film rolling machine is: described roll shaft 1 is cylindrical roll body, is all respectively equipped with a shaft shoulder 4 at roll shaft 1 two ends, the shaft shoulder 4 be shaped as cylinder and roll shaft 1 global formation, global formation can be strengthened the rigidity of roll shaft; The left side cylinder of roll shaft 1 is provided with right-handed thread, on the cylinder of right side, is provided with left hand thread, when can making like this roll shaft 1 move, can make the film that is positioned at roll shaft below fully flatten; The centre of roll shaft 1 is provided with one section of smooth cylinder, and the length of smooth cylinder is 20cm, so can reduce the difficulty of processing of roll shaft 1, is also in order fully to improve the effect that film flattens; The length of roll shaft 1 is consistent with the length of conveyer belt 8 rollers, when length is consistent, just larger film can be flattened.Support 2 main bodys are an optical axis 6, are connected with a base for supporting 7 in any one end of optical axis 6, base for supporting 7 be shaped as a conical cylinder, for conical cylinder can strengthen and the contact area on ground, improve the stability of this device; The other end of optical axis 6 is provided with a back-up block 5, and back-up block 5 is the cavity of a rectangle, is provided with a manhole in the middle of back-up block 5; Two shaft shoulders 4 of roll shaft 1 respectively with back-up block 5 inside of two supports 2 are installed, and whole roll shaft 1 can realize 360 ° of rotations, only has and realizes the motion that 360 ° of rotations just can whole roll shaft, reaches the effect of this device.
In order to realize better the special flattening device of this PVC film rolling machine, the structural representation between this device and calender conveyer belt and winder as shown in Figure 2: this device is positioned at the centre position of conveyer belt and the winder of calender, and in the below of PVC film, this device self does not have power source, participates in the motion of calender.
The use state of the special flattening device of this PVC film rolling machine: when calender work, PVC film production is out time, can be placed in winder through conveyer belt, and the centre position of this device in conveyer belt and winder, and in the below of PVC film, when film is by after conveyer belt, can be through this device, because the right-handed thread of the left side cylinder of the roll shaft 1 of this device can produce a kind of trend to left movement, and the left hand thread of roll shaft 1 right side cylinder, can produce a kind of trend moving right, rely on the effect of frictional force, so the PVC film through top is flattened automatically, flatten effective, simple in structure.
