Abstract
The utility model relates to a tension device for a plastic film rolling and winding section. The tension device comprises a crimping roller and a mandrel inserted with a winding core barrel, wherein the crimping roller drives a plastic film coiled on the mandrel; and a transitional roller is also arranged at the upstream of the crimping roller. The tension device is characterized in that a tension device is arranged at the upstream of the transitional roller and comprises a tension roller arranged on a bearing pedestal; and the bearing pedestal is arranged on a base through a pressing sheet resistor. The tension device has the advantages that the pressing sheet resistor can feed back tension in real time; by a system, the rotating speed of the crimping roller can be automatically adjusted, and the tension can be kept constant; and the film end face of a rolling shaft is tidy, and shrinkage of a product is reduced. The tension device is simple and reasonable in structure, and a rolling production line is relatively smooth.
Description
Technical field
The utility model belongs to the production technical field of plastic film, relates in particular to a kind of tensioner of the plastic film calendering section of batching.
Background technology
Polyvinyl chloride film is in the calendering formation process, goods batch a lot of forms, single roller surface reel is a kind of form more commonly used wherein, but single roller surface reel in use, the size of the spool that goods batch is larger for batching influential effect, for batching larger spool, increase along with spool, weight is increasing, cause the friction force of the face that batches increasing, the power of batching is increasing, causes film to stretch in coiling process increasing, and the end face of last spool there will be injustice, acclive phenomenon to occur.Thereby directly affect the finished product outward appearance, and larger on the impact of the interior quality of film, affect the internal stress of film, and directly affect the nominal dimension, planeness etc. of film.
Summary of the invention
The utility model provides a kind of convenient operation for solving the technical matters existed in known technology, and precise control makes the tensioner of the press production line plastic film calendering more smoothly section of batching.
The technical scheme that the utility model is taked for the technical matters existed in the solution known technology is:
The tensioner of the plastic film calendering section of batching, comprise crimping roller and the mandrel that is installed with rolling core cylinder, crimping roller drives and is wrapped in the plastic film on mandrel, the crimping roller upstream also is provided with transition roller, it is characterized in that: the transition roller upstream section also is provided with tensioner, described tensioner comprises the jockey pulley be arranged on bearing seat, and described bearing seat is arranged on base by compressing tablet resistance.
The utility model can also adopt following technical scheme:
Described compressing tablet resistance passes to control system by tension signal, and controls the speed of crimping roller by control system.
Advantage and the good effect that the utlity model has are:
After the utility model has adopted above technical scheme, by compressing tablet resistance, tension force is carried out to Real-time Feedback, by system, make crimping roller automatically carry out speed adjustment, keep constant tension, the retraction etc. of guaranteeing that the film end face of spool is neat and reducing goods.The utility model is simple and reasonable, guarantees that press production line is more smooth and easy.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, jockey pulley; 2, compressing tablet resistance; 3, crimping roller; 4, rolling core cylinder; 5, mandrel; 6, bearing seat; 7, base; 8, plastic film; 9, transition roller.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of tensioner of the plastic film calendering section of batching, comprise crimping roller 3 and the mandrel 5 that is installed with rolling core cylinder 4, crimping roller drives and is wrapped in the plastic film 8 on mandrel, the crimping roller upstream also is provided with transition roller 9, the transition roller upstream also is provided with tensioner, and tensioner comprises the jockey pulley be arranged on bearing seat, and bearing seat is arranged on base by compressing tablet resistance.Compressing tablet resistance passes to control system by tension signal, controls the speed of crimping roller by control system.
Operating principle of the present utility model is:
In actual use, crimping roller drives the plastic film materials volume twisted on the core cylinder and rotates, carry out the rolling of plastic film, by compressing tablet resistance, the tension force on plastic film is carried out to Real-time Feedback, tension signal is passed to control system (not looking out in figure), by control system, make crimping roller automatically carry out speed adjustment, keep constant tension, thus the retraction etc. of guaranteeing that the film end face of spool is neat and reducing goods.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
Claims (2)
1. a plastic film rolls the tensioner of the section of batching, comprise crimping roller and the mandrel that is installed with rolling core cylinder, crimping roller drives and is wrapped in the plastic film on mandrel, the crimping roller upstream also is provided with transition roller, it is characterized in that: the transition roller upstream section also is provided with tensioner, described tensioner comprises the jockey pulley be arranged on bearing seat, and described bearing seat is arranged on base by compressing tablet resistance.
