Description
Technical field
The utility model belongs to device of plastic processing, specifically a kind of helicla flute felt wrapped roll.
Background technology
Packaging industry is thriving at present, and plastic packets has been dressed up an indispensable part in our life.The plastics package of many toys all is stamped to form by plastic plate.Existing plastic plate processing equipment adopts two kinds of technology, and a kind of is the calendering technology, and another kind is extrusion technique.Extrusion technique is more advanced, but its production equipment is expensive, and production cost is very high.Calendering technology production cost is low, but the product surface quality that calender in the market processes is relatively poor, can produce ripple and bubble, uneven thickness, wherein crucial reason is exactly that felt wrapped roll can not be evenly cooling, cause the rolling temperature of same felt wrapped roll inconsistent, cause product quality problem.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of helicla flute felt wrapped roll.
A kind of helicla flute felt wrapped roll is characterized in that comprising inner and outer tubes, and described inner tube is hollow, is provided with helicla flute on described outer tube, and an end of described helicla flute felt wrapped roll is provided with water inlet, and the other end is provided with water return outlet.Described a kind of helicla flute felt wrapped roll, an end that it is characterized in that described inner tube is provided with interior water inlet, position corresponding with the interior water inlet on inner tube on described outer tube is provided with outer water inlet, tube connector by hollow between described interior water inlet and outer water inlet connects, the other end of described inner tube arranges interior water return outlet, position corresponding with the interior water return outlet on inner tube on described outer tube is provided with outer water return outlet, and the tube connector by hollow between described interior water return outlet and outer water return outlet connects.
Described a kind of helicla flute felt wrapped roll is characterized in that described interior water inlet, outer water inlet, interior water return outlet and outer water return outlet respectively have 3.
Described a kind of helicla flute felt wrapped roll is characterized in that described interior water inlet, outer water inlet, interior water return outlet and outer water return outlet are symmetric respectively on the circumference of inner and outer tubes, respectively the circular arc of inner and outer tubes is classified in three categories minute.
Described a kind of helicla flute felt wrapped roll is characterized in that described helicla flute comprises 3 sections to the helicla flute of inclined, and described outer water inlet and outer water return outlet are separately positioned on every section spiral fluted starting point and destination county.
Described a kind of helicla flute felt wrapped roll is characterized in that the cross section of described spiral fluted incline direction and inner and outer tubes is 20 °-45° angle.
Described a kind of helicla flute felt wrapped roll is characterized in that described spiral fluted width is 1-5cm.
Described a kind of helicla flute felt wrapped roll is characterized in that the distance between described inner and outer tubes is 1-5cm.
Helicla flute felt wrapped roll of the present utility model, simple in structure, easy to use, can make felt wrapped roll evenly cooling, improved quality and the qualification rate of product.
Description of drawings
Fig. 1 is the structural representation of helicla flute felt wrapped roll of the present utility model;
In figure, 1-inner tube; 2-outer tube; 3-interior water inlet; 4-helicla flute; 5-outer water inlet; 6-tube connector.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
as shown in Figure 1, a kind of helicla flute felt wrapped roll of the present utility model, comprise inner and outer tubes, distance between inner and outer tubes is 3cm, inner tube is hollow, be provided with 3 sections on outer tube to the helicla flute of inclined, the cross section of spiral fluted incline direction and inner and outer tubes is 30 ° of angles, the spiral fluted width is 3cm, one end of inner tube is provided with interior water inlet, position corresponding with the interior water inlet on inner tube on outer tube is provided with outer water inlet, tube connector by hollow between interior water inlet and outer water inlet connects, the other end of inner tube arranges interior water return outlet, position corresponding with the interior water return outlet on inner tube on outer tube is provided with outer water return outlet, tube connector by hollow between interior water return outlet and outer water return outlet connects.Interior water inlet, outer water inlet, interior water return outlet and outer water return outlet respectively have 3, be symmetric on the circumference of inner and outer tubes respectively, respectively the circular arc of inner and outer tubes is classified in three categories minute, outer water inlet and outer water return outlet are separately positioned on every section spiral fluted starting point and destination county.
During work, frosted felt wrapped roll on the outer cover of helicla flute felt wrapped roll, inject cold water in inner tube, cold water flows to outer water inlet from interior water inlet, along the helicla flute Uniform Flow, makes the felt wrapped roll uniform decrease in temperature, cold water absorbs heat simultaneously becomes hot water, pass back into inner tube from outer return pipe and interior return pipe again and cool, flowing to the inner tube other end becomes again cold water, reciprocation cycle like this.
The above is only preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., within all being included in protection domain of the present utility model.
