Description

A kind of revocable plastic sheeting rolling-up mechanism of wind-up roll

Technical field

This utility model is related to plastic sheeting production technical field, more particularly to a kind of revocable plastic sheeting of wind-up roll Rolling-up mechanism.

Background technology

Plastic sheeting is that fusible polymer becomes soft uniform lamella by processing and forming, usually uses polychlorostyrene second Alkene, polyethylene, polypropylene, polystyrene and other resins are made.In plastic sheeting process of manufacture, by polymeric resin Heated after melting extrusion sheet by extruder, drawn in the range of the proper temperature more than vitrification point, below fusing point Stretch, make polymeric resin material drawing and forming in the case of thermoplasticity is preferable, then entered after further processing to wind.

Existing plastic film winding device, is the turning by wind-up roll by plastic sheeting directly on wind-up roll It is dynamic, plastic sheeting winding is got up, with the winding of plastic sheeting, winding radius is increasing, and plastic sheeting easily crimps change Shape, and the wind-up roll of existing wrap-up is generally fixed in frame, and the radius of winding is restricted, and winding radius is little, receives After the completion of volume, the plastic sheeting of rolling is difficult to remove, and production efficiency is adversely affected.

The content of the invention

This utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of wind-up roll revocable plastic sheeting winding Mechanism, the rolling-up mechanism winding is steady, and winding radius is big.

This utility model for achieving the above object, is employed the following technical solutions：A kind of revocable plastic sheeting of wind-up roll Rolling-up mechanism, including door frame, active transfer roller, carrying roller, wind-up roll, change speed gear box and motor, the active transfer roller and carrying roller can turn Dynamic is fixed on door frame bottom, and the active transfer roller and carrying roller are parallel to each other, and plastic sheeting, the receipts are wound on the wind-up roll Winding up roller is contacted located at active transfer roller and carrying roller middle upper part, the plastic sheeting on the wind-up roll with active transfer roller and carrying roller, institute The crossbeam bottom for stating door frame is removably provided with two cylinders, and the cylinder other end is connected with push rod, the push rod other end Semicircular indentations are provided with, the half round cut of described two push rods is stuck in wind-up roll two ends, the active transfer roller and change speed gear box Connection, the change speed gear box is by motor-driven.

Described active transfer roller is identical with idler diameter.

Described active transfer roller outer round surface is provided with helicla flute.

Described active transfer roller and carrying roller outer round surface wraps up rubber.

Shaft coupling is provided between described active transfer roller and change speed gear box.

The beneficial effects of the utility model are：This utility model wind-up roll is not fixed on door frame, active transfer roller friction belt Dynamic wind-up roll is rotated, and realizes winding function, and winding radius is big；Carrying roller is not only acted as and supports the effect of wind-up roll, and can be flattened Plastic sheeting is Texturized on wind-up roll；Cylinder is telescopic, and the push rod of cylinder connection blocks wind-up roll two ends, makes winding Roller stable movement；When collecting plastic sheeting, push rod need to only disengaged with wind-up roll just can very easily by the modeling of rolling Material thin film is removed.

Specific embodiment

With reference to the accompanying drawings and examples the utility model is described in further detail：

As shown in FIG. 1 to 3, a kind of revocable plastic sheeting rolling-up mechanism of wind-up roll, including door frame 10, active transfer roller 4th, carrying roller 11, wind-up roll 7, change speed gear box 2 and motor 1, the active transfer roller 4 and carrying roller 11 are rotatably fixed on the bottom of door frame 10 Portion, the active transfer roller 4 and carrying roller 11 it is parallel to each other, on the wind-up roll 7 wind plastic sheeting 6, the wind-up roll 7 located at master Dynamic transfer roller 4 and the middle upper part of carrying roller 11, the plastic sheeting 6 on the wind-up roll 7 is contacted with active transfer roller 4 and carrying roller 11, described The crossbeam bottom of door frame 10 is removably provided with two cylinders 9, and the other end of the cylinder 9 is connected with push rod 8, and the push rod 8 is another One end is provided with semicircular indentations, and the half round cut of described two push rods 8 is stuck in the two ends of wind-up roll 7, the active transfer roller 4 with Change speed gear box 2 connects, and the change speed gear box 2 is driven by motor 1.

Described active transfer roller 4 is identical with the diameter of carrying roller 11.

The described outer round surface of active transfer roller 4 is provided with helicla flute 5.

Described active transfer roller 4 and the outer round surface of carrying roller 11 wraps up rubber.

Shaft coupling 3 is provided between described active transfer roller 4 and change speed gear box 2.

During work, first plastic sheeting 6 is wound into some circles on wind-up roll 7, afterwards wind-up roll 7 is put in into active transfer roller 4 And carrying roller 11 between, rubbed by active transfer roller 4 and drive wind-up roll 7 to rotate, winding function is realized, because wind-up roll 7 is not fixed on On door frame 10, so winding radius is big；Carrying roller 11 not only acts as the effect of wind-up roll 7 that supports, and can flatten modeling on wind-up roll 7 Expect the Texturized of thin film 6；The push rod 8 being connected with cylinder 9 is blocked into the two ends of wind-up roll 7, due to cylinder 9 be it is telescopic, In the case that winding radius is increasing, wind-up roll 7 can be moved up and down smoothly；When collecting plastic sheeting 6, only push rod 8 need to be made Disengaging with wind-up roll 7 just very easily can remove the plastic sheeting 6 of rolling.

This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without Improvement directly applies to other occasions, within protection domain of the present utility model.
