Abstract
The utility model discloses a vacuum sizing box with a double-chamber structure, which comprises a box body that is internally provided with a spraying system. The spraying system is provided with an ABS atomizing nozzle. The vacuum sizing box is provided with a vacuum box sealing baffle device which divides the vacuum sizing box into two relatively air-sealed vacuum chambers at the approximately central position along the axial direction. According to the vacuum sizing box with the structure of the utility model, as two chambers are independently sealed and do not interfere with each other in the using process, and the two chambers are respectively driven by one set of vacuum pump and water pump. The actual production states of the pipes in two chambers can be regulated to different vacuum degrees thus the control to the outer diameter of the pipe is easily relatively. Furthermore, in pipe drawing test of starting and stopping, vacuum can be ensured in at least one half of the vacuum boxes. The waste products are reduced and the qualified rate of product is increased.
Description
Technical field
The utility model relates to a kind of vacuum sizing case, particularly relates to a kind of vacuum sizing case that is used for plastic pipe sizing with double-chamber structure.
Background technology
The production equipment of plastic tube product line comprises console, extruder, vacuum sizing case and cutting machine, raw material is inserted in the feeding port of extruder, the stirring of heating, constantly forward from the extrusion molding of head extrusion, becoming the cross section is the thin cylinder section bar of annular, enters the vacuum sizing case then and carries out cooling and shaping through spiral propeller.The vacuum sizing case comprises casing, is provided with spray system in the casing, and ABS atomizer, casing are connected with water pump and vacuum extractor, and the casing length of vacuum sizing case is generally 6 meters.The calibration sleeve that plastic pipe is carried out sizing is positioned at the vacuum sizing case; spray system by the vacuum sizing case is cooled off calibration sleeve; and then reach cooling purpose to plastic pipe; in the prior art; the vacuum sizing case all is a single cell structure; tube outer diameter and out-of-roundness were not easy control when the vacuum sizing case of single cell structure was to plastic pipe sizing like this, and when start examination trombone slide and shutdown, the technical problem of existence is to occur the tubing waste product easily in addition.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly produces when the plastic pipe vacuum sizing that waste product is few, tube outer diameter, the out-of-roundness vacuum sizing case with double-chamber structure of control easily.
For solving the problems of the technologies described above, the utlity model has the vacuum sizing case of double-chamber structure, comprise casing, spray system is arranged in the casing, spray system is provided with the ABS atomizer, and described vacuum sizing case roughly centre position vertically is provided with and the axial vertical vacuum tank seal diaphragm device that described vacuum sizing case is divided into the vacuum chamber of two relative hermetic seals.
As to further improvement of the utility model, described vacuum tank seal diaphragm device comprises the corrosion resistant plate and the flange that O-ring seal is housed that cooperates with this steel plate that are provided with the middle part ring.
Adopt the vacuum sizing case of said structure, because the negative pressure adjustment of vacuum tank is to regulate vacuum by the valve of vacuum tank to replenish the air capacity size, in use, adjust vacuum according to the tube outer diameter size, because two chamber is two independent closed, do not disturb mutually again, each is driven by a cover vavuum pump, water pump, dual-chamber tube material practical condition can be adjusted into different vacuum, the control of tube outer diameter is relatively easy like this.When start examination trombone slide and shutdown, can guarantee that at least one partial vacuum case has vacuum in addition, reduce the appearance of waste product, improve the qualification rate of product.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail,
Fig. 1 is a kind of schematic top plan view with vacuum sizing case of double-chamber structure that proposes by invention scheme of the present utility model.
Fig. 2 is the cross-sectional schematic along the A-A line of vacuum sizing case shown in Figure 1.
Fig. 3 is that vacuum tank seal diaphragm device shown in Figure 2 is along B-B line cross-sectional schematic.
The specific embodiment
Among Fig. 1, Fig. 2, Fig. 3, the vacuum sizing case that the utlity model has double-chamber structure comprises casing 1, spray system 2 is arranged in the casing, spray system 2 is provided with ABS atomizer 3, and vacuum sizing case roughly centre position vertically is provided with and the axial vertical vacuum tank seal diaphragm device 6 that described vacuum sizing case is divided into the vacuum chamber 4,5 of two relative hermetic seals.This vacuum tank seal diaphragm device 6 can be the corrosion resistant plate 7 and the flange that O-ring seal 8 is housed 9 that cooperates with this steel plate that are provided with the middle part ring.
Claims (2)
1. vacuum sizing case with double-chamber structure, comprise casing, spray system is arranged in the casing, spray system is provided with the ABS atomizer, it is characterized in that: described vacuum sizing case roughly centre position vertically is provided with and the axial vertical vacuum tank seal diaphragm device that described vacuum sizing case is divided into the vacuum chamber of two relative hermetic seals.
