Abstract
The utility model belongs to the extruder field, concretely relates to extruder hot melt parison wall thickness adjustment device. Including the nut and with nut matched with dabber, the dabber is located the inside of adjusting extruder mould main part, the nut passes through the clamp plate to be fixed in the upper end of extruder mould main part, the axle sleeve is extruded in the lower extreme setting of extruder mould main part, first dabber is extruded in the lower extreme setting of dabber. The diameter of extruding first dabber is less than the internal diameter of extruding the axle sleeve. It also describes for the horn mouth for horn mouth form, the corresponding axle sleeve inner wall of extruding to extrude first dabber lower extreme. The utility model discloses a nut regulation, the control of the hot melt parison wall thickness that obtains is very stable and accurate, and product quality is high, simple structure, it is easy to use, and the inconvenience of changing or change extrusion tooling has been avoided to the wall thickness of adjustment extruder hot melt parison that can convenient and fast.
Description
Technical field
The utility model belongs to extruder field, is specifically related to a kind of extruder hot melt system of parison wall thickness conditioning equipment.
Background technology
Extrusion-blown modling is, with extruder, plastic pellet heating and melting is become hot melt parison, makes closed hot melt preform blowup in a mold form the method for hollow product by means of gas pressure.Its main working process is: material, first by after extruder plastication, is extruded into cylindrical shape hot melt parison through die head, in certain gas pressure mould, makes hot melt parison be cooled to the product of definite shape and wall thickness.Wall thickness control mechanism is the key position of hot melt system of parison wall thickness, decides the properties of product.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of extruder hot melt system of parison wall thickness conditioning equipment, and structure is simple, can adjust the wall thickness of extruder hot melt parison.
Extruder hot melt system of parison wall thickness conditioning equipment described in the utility model, the mandrel comprising nut and match with nut, mandrel is positioned at the inside regulating extruding machine mold main body, nut is fixed on the upper end of extruding machine mold main body by pressing plate, the lower end of extruding machine mold main body is arranged extrudes axle sleeve, and the lower end of mandrel arranges extruder head mandrel.
The inside of mandrel and extruder head mandrel is provided with an air blowing tracheae.
The diameter of extruder head mandrel is less than the internal diameter extruding axle sleeve.
Extruder head mandrel lower end is bell mouth shape, and corresponding sleeve lining of extruding also is bell mouth shape.
Nut is fixed on the upper end of extruding machine mold main body by pressing plate, so that adjusting nut Shi Nengdai moving mandrel moves up and down.
During use, the hot melt moulding mixture extruded enters extruder head mandrel through the feeding-passage of extruding machine mold main body and extrudes to be extruded in passage between axle sleeve, pass through rotating nut, band moving mandrel moves up and down, mandrel drives extruder head mandrel to move up and down, make extruder head mandrel and the gap of extruding between axle sleeve there occurs change, the hot melt system of parison wall thickness that extruder is extruded is adjusted, and can obtain the hot melt parison that uniform wall thickness thickness is different.
In sum, the utility model has the following advantages:
(1) the utility model is regulated by nut, and the control of the hot melt system of parison wall thickness obtained is highly stable and accurate, and product quality is high.
(2) the utility model structure is simple, uses easily, conveniently can adjust the wall thickness of extruder hot melt parison, avoids the inconvenience changed or change extrusion die.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-mandrel, 2-nut, 3-pressing plate, 4-extruding machine mold main body, 5-air blowing tracheae, 6-extruder head mandrel, 7-extrudes axle sleeve.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further.
Embodiment
A kind of extruder hot melt system of parison wall thickness conditioning equipment, as shown in Figure 1, the mandrel 1 comprising nut 2 and match with nut, mandrel 1 is positioned at the inside regulating extruding machine mold main body 4, nut 2 is fixed on the upper end of extruding machine mold main body 4 by pressing plate 3, the lower end of extruding machine mold main body 4 is arranged extrudes axle sleeve 7, and the lower end of mandrel 1 arranges extruder head mandrel 6.
The inside of mandrel 1 and extruder head mandrel 6 is provided with an air blowing tracheae 5.
The diameter of extruder head mandrel 6 is less than the internal diameter extruding axle sleeve 7.
Extruder head mandrel 6 lower end is bell mouth shape, and corresponding axle sleeve 7 inwall of extruding also is bell mouth shape.
During use, the hot melt moulding mixture extruded enters extruder head mandrel 6 through the feeding-passage of extruding machine mold main body 4 and extrudes to be extruded in passage between axle sleeve 7, by rotating nut 2, band moving mandrel 1 moves up and down, mandrel 1 drives extruder head mandrel 6 to move up and down, make extruder head mandrel 6 and the gap of extruding between axle sleeve 7 there occurs change, the hot melt system of parison wall thickness that extruder is extruded is adjusted, and can obtain the hot melt parison that uniform wall thickness thickness is different.
