Abstract
The utility model relates to a movable roller which comprises a roller body, a support shaft and a bearing. The movable roller is characterized in that the support shaft passes through the roller body; the bearing is arranged at one end of the support shaft; a clamping groove is formed on one end, far away from the bearing, of the support shaft; and one end of the support shaft, provided with the clamping groove, is connected with a motor. The movable roller is simple in structure, formed by not changing the basic shape of a milling roller and easy to assemble, so that the movable roller can be used for directly replacing the milling roller on a film blowing machine and is convenient to disassemble.
Description
Technical field
The utility model relates to film blowing device field, specifically a kind of movable roll.
Background technology
Blown film (Blow Membrane) is a kind of plastic working method, refers to the plastic pellet heating and melting is blown out a kind of plastic processing of film again.If the film that blows out with virgin material, color and luster is even, and clean, finished product stretches.If the plastic pellet with the waste plastics that reclaims is made will add pigment usually when making film, the film of making may be just painted irregular, crisp and easily broken, and price is also lower.Blown film material by the inflation film manufacturing machine production of specialty is applicable to various high-grade blister-packs.This film is due to its good barrier property, and is fresh-keeping, damp proof, frost protection, and oxygen barrier, oil resistant can be widely used in the weight packing.As various fresh fruits, meat product, pickles, fresh milk, liquid beverage, medical supplies etc.If non-professional inflation film manufacturing machine or inflation film manufacturing machine do not make on sound lines in process, the coating materials of making so may be also substandard products.Most of PE are used for the blown film film processed, and general low density PE (LDPE) or linear low close PE (LLDPE) are available.The HDPE film-grade generally is used for requiring the place of superior draftability and fabulous barrier properties.For example, the HDPE film is usually used in commodity bag, groceries bag and food Package.The PE processing film is generally with common blown film processing or the flat processing method of squeezing.
General inflation film manufacturing machine end all has a roll, is used for the rolling of final film product, when rolling is enough large, namely shuts down, and roll is walked with traveling crane, then puts another root roll, then start.Generally in order to guarantee the stability of roll, roll two ends all adopt rigid bearing to fix, and this just makes the movement of roll must use driving to be sling in roll two ends, but the cleanliness factor of often having relatively high expectations in the blown film workshop, this application for driving is extremely inconvenient.The roll that also there is no at present the movable that is used for the inflation film manufacturing machine end a kind of simple in structure, easy for installation
Summary of the invention
The utility model is above technical problem just, provides a kind of simple in structure, the movable roll that is used for the inflation film manufacturing machine end easy for installation.
The utility model is achieved through the following technical solutions:
A kind of movable roll comprises roll body, back shaft, bearing, it is characterized in that back shaft passes roll body, and bearing is arranged on back shaft one end, and back shaft arranges draw-in groove away from bearing one end.Back shaft band draw-in groove one end is connected with motor.
The utility model is simple in structure, does not change the basic profile of roll, is easy to install, and can directly replace the roll on inflation film manufacturing machine, can dismantle easily.
Description of drawings
Accompanying drawing Fig. 1 is structural representation of the present utility model, wherein:
The 1-roll body, 2-back shaft, 3-bearing.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of movable roll comprises roll body 1, back shaft 2, bearing 3, it is characterized in that back shaft passes roll body 1, and bearing 3 is arranged on back shaft 2 one ends.Back shaft 2 arranges draw-in groove away from bearing 3 one ends.Back shaft 2 band draw-in groove one ends are connected with motor.
During use, the back shaft 2 with bearing 3 is placed on support, is connected with motor away from back shaft 3 one ends of bearing 2; when film coil is enough large; first shut down, then with the be connected disconnection of back shaft 3 with motor, can will have volume to have the roll of film to unload easily.
The utility model is simple in structure, does not change the basic profile of roll, is easy to install, and can directly replace the roll on inflation film manufacturing machine, can dismantle easily.
Claims (2)
1. a movable roll, comprise roll body, back shaft, bearing, it is characterized in that back shaft passes roll body, and bearing is arranged on back shaft one end, and back shaft arranges draw-in groove away from bearing one end.
2. a kind of movable roll according to claim 1, is characterized in that described back shaft band draw-in groove one end is connected with motor.
