Description

A kind of PVC film wrap-up

Technical field

The utility model relates to PVC film technical field, in particular to a kind of PVC film wrap-up.

Background technique

Currently, PVC film has won the joyous of people with its good performance, simple technique and other plurality of advantages gradually The heart has been more and more people to accept and has approved, PVC material has lightweight, heat-insulated, heat preservation, moisture-proof, fire-retardant, easy construction etc. Feature, specification, color, pattern are various, are rich in dicoration, and it is a series of to can be applied to room interior wall, window, floor and furred ceiling etc. Decoration, be one of the ornament materials being most widely used in plastic materials.The production technology of existing PVC calendered film, packet It includes following steps: (1) being pressed and molded；(2) embossing molding；(3) cooling and shaping；(4) it finally carries out trimming and batches, it is final to be put in storage Monitoring.

Existing PVC film wrap-up is mostly that motor drives a round roller rotation, and it is enterprising that PVC film is then wrapped in round roller Row winding, as soon as there are a drawbacks for this winding mode: that is exactly not notice that the PVC film after winding has slightly after winding It may loosen automatically, so that biggish gap is generated between PVC film and round roller, so that the more fluffy confusion of PVC film winding is very It is completely unstable to completely disengaging round roller.

Utility model content

The utility model lies in that PVC film one kind that automatic bulking is even detached from after winding can be prevented by providing one kind PVC film wrap-up.

What the above-mentioned technical effect of the utility model was achieved through the following technical solutions:

A kind of PVC film wrap-up, including bracket are successively rotatably connected to the first guide reel, the second guide reel on bracket And wind-up roll, wind-up roll are driven by driving motor and are rotated, it is characterised in that: compression is provided with right above the wind-up roll Component holds down assembly including pressing roller, holddown spring, and pressing roller is parallel to wind-up roll, and the both ends of pressing roller are rotatably connected to Moving axis, holddown spring is fixedly connected with the rotating shaft and cash pledge spring is located at the top of rotation axis, and holddown spring is far from rotation axis One end is affixed with bracket, holddown spring in the raw when, pressing roller abuts just with wind-up roll.

PVC film the first guide reel and the second guide reel and then is wound on wind-up roll from successively bypassing.Driving motor Wind-up roll is driven constantly to rotate, PVC film also can constantly be wound on wind-up roll, and during winding, pressing roller is compressing bullet It is abutted always with the PVC film of wind-up roll surface wrap under the resilient force of spring, and the PVC film for winding roller surface winding is thicker, Then the pressing force of pressing roller is bigger, and PVC is just less susceptible to fluffy or even falls off, and improves the winding stability of PVC film, and due to Pressing roller is to be rotatablely connected with rotation axis, therefore although PVC film is compacted roll-in and lives, but pass through pressure during winding The rotation of tight roller can also greatly reduce winding resistance, ensure that winding smoothness.

The utility model is further arranged to: first guide reel is located at the surface of the second guide reel, wind-up roll with Second guide reel is located at same level height, and PVC film is wound downwards from the top of the first guide reel, then from the second guide reel Bottom bypasses, and final winding is in wind-up roll.

The utility model has the advantages that

1, it is held down assembly by setting, so that PVC film of the winding on wind-up roll will not be loosened and be fallen off easily, thus Improve the winding stability of PVC film.

2, by the first guide reel of setting and the second guide reel, guiding function, a side on the one hand can be played to PVC film Face is wound again after being tensioned PVC film, to improve the quality and efficiency of winding.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1, bracket；2, the first guide reel；3, the second guide reel；4, wind-up roll；5, it holds down assembly；51, pressing roller； 52, holddown spring；521, rotation axis；6, driving motor.

Specific embodiment

1 pair of the utility model is further described with reference to the accompanying drawing.

A kind of PVC film wrap-up, including bracket 1 are successively rotatably connected to the guidance of the first guide reel 2, second on bracket 1 Roller 3 and wind-up roll 4, wind-up roll 4 drive rotation by driving motor 6, and the surface of the wind-up roll 4, which is provided with, to hold down assembly 5, holding down assembly 5 includes pressing roller 51, holddown spring 52, and pressing roller 51 is parallel to wind-up roll 4, and the both ends of pressing roller 51, which rotate, to be connected It is connected to rotation axis 521, holddown spring 52 is fixedly connected with rotation axis 521 and holddown spring 52 is located at the top of rotation axis 521, pressure The tight one end of spring 52 far from rotation axis 521 and bracket 1 are affixed, holddown spring 52 in the raw when, pressing roller 51 and receipts Winding up roller 4 abuts just.

PVC film the first guide reel 2 and the second guide reel 3 and then is wound on wind-up roll 4 from successively bypassing.Driving Motor 6 drives wind-up roll 4 constantly to rotate, and PVC film also can constantly be wound on wind-up roll 4, during winding, pressing roller 51 It is abutted always with the PVC film of 4 surface wrap of wind-up roll under the resilient force of holddown spring 52, and 4 surface of wind-up roll is wound PVC film it is thicker, then the pressing force of pressing roller 51 is bigger, and PVC is just less susceptible to fluffy or even falls off, and improves the winding of PVC film Stability, and since pressing roller 51 is rotatablely connected with rotation axis 521, although PVC film is compacted roller 51 and pushes down, but It is that winding resistance can also be greatly reduced by the rotation of pressing roller 51 during winding, ensures that winding smoothness.

First guide reel 2 is located at the surface of the second guide reel 3, and wind-up roll 4 and the second guide reel 3 are located at same water Flat height, and the top of PVC film from the first guide reel 2 is wound downwards, then is bypassed from the bottom of the second guide reel 3, it is final to wind In wind-up roll 4.

PVC film passes through the first guide reel 2 first under upper, then bypasses again from the bottom of the second guide reel 3, finally again It winding on wind-up roll 4, on the one hand the first guide reel 2, the second guide reel 3 all guide limitation to the direction of travel of PVC film, It prevents PVC film from directly contacting contamination dust with bracket 1, on the other hand tension can be played to PVC film, to improve PVC The winding quality and winding efficiency of film.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
