Abstract
The invention relates to an extruding machine used for a medical PVC material. The extruding machine comprises a machine frame, a power system and a screw assembly, wherein the power system is arranged on the machine frame, and the screw assembly is connected with the power system. A charging system is arranged on the upper portion of the screw assembly and comprises a hopper, a charging motor and a charging assembly. The charging assembly is connected to the screw assembly. A heating device is arranged on the periphery of the screw assembly. A fan and a temperature sensor are arranged on the heating device. The heating device is further connected to a vacuum pumping unit through a vacuum air pipe. The extruding machine is high in automation degree and capable of achieving heating and automatic real-time control over the material during the PVC material conveying process through the screw assembly and conducting extraction and separation on PVC molecular groups, improves the overall purity of the material, and guarantees the quality of products.
Description
Technical field
The present invention relates to the plant equipment in medical PVC material field, especially relate to a kind of extruder for medical PVC material。
Background technology
PVC material and polrvinyl chloride, for the white powder of impalpable structure, be commonly used for making pipe fitting and industrial packaging, article of everyday use etc., it may also be used for make the medical supplies such as acid and alkali-resistance flexible pipe, cable sheathing, insulating barrier and medical tube for transfusion。Extruder is the capital equipment of processing PVC, by screw rod rotate produce pressure and shearing force, can make material can sufficiently conducted plasticizing and Homogeneous phase mixing, by mouth die molding。Being commonly used to produce blood bag, conduit etc. at medically PVC material extruder, existing medical PVC material extruder adopts static state heating, easily causes heating uneven, material can not fully plastify, and the impurity in PVC material mixes with the solution after plasticizing, affect mould molding, reduce conforming product rate。
Summary of the invention
Present invention seek to address that drawbacks described above, it is provided that a kind of automaticity height is for the extruder of medical PVC material。
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of extruder for medical PVC material, including frame, it is arranged at the dynamical system in frame and the screw arbor assembly being connected with dynamical system, screw arbor assembly is arranged over charging system, described charging system includes hopper, reinforced motor and reinforced assembly, reinforced assembly is connected to screw arbor assembly, described screw arbor assembly periphery is provided with heater, heater is provided with blower fan and temperature sensor, described heater is connected to vacuum exhaust group also by vacuum trachea。
In a preferred embodiment of the present invention, dynamical system includes the mair motor, reduction gear box and the distribution gear case that are sequentially connected with, is connected by coupling assembly between mair motor and minimizing gear-box。
In a preferred embodiment of the present invention, heater includes heating collar one, heating collar two, heating collar three and heating collar four
The invention has the beneficial effects as follows: automaticity of the present invention is high, the process of screw arbor assembly transport PVC material realizes the heating to material and automatization controls in real time, carry out PVC micel extracting separating simultaneously, improve the overall purity of material, it is ensured that the quality of product。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described。
Fig. 1 is the structural representation of the present invention。
Detailed description of the invention
A kind of extruder for medical PVC material as shown in Figure 1, including frame 1, the dynamical system being arranged in frame 1 and the screw arbor assembly 3 that is connected with dynamical system, screw arbor assembly 3 is arranged over charging system, charging system includes hopper 41, reinforced motor 42 and reinforced assembly 43, reinforced assembly 43 is connected to screw arbor assembly 3, screw arbor assembly 3 periphery is provided with heater, and heater is provided with blower fan 6 and temperature sensor 7, and heater is connected to vacuum exhaust group 9 also by vacuum trachea 8。
Dynamical system includes the mair motor 21, reduction gear box 22 and the distribution gear case 23 that are sequentially connected with, is connected by coupling assembly 24 between mair motor 21 and minimizing gear-box 22。
Heater includes heating collar 1, heating collar 2 52, heating collar 3 53 and heating collar 4 54。
PVC material through pre-treatment is entered by hopper, owing to PVC material is delivered in screw arbor assembly by the cooperation of reinforced motor and reinforced assembly, PVC material is transported on stock-cutter by screw arbor assembly, it is provided with heater in screw arbor assembly periphery, the material transported on screw arbor assembly fully can be heated, temperature sensor and blower fan it is provided with, it is achieved the real time temperature of material is controlled due to heater；Again owing to heater connects vacuum exhaust group also by trachea, the PVC micel on screw arbor assembly can be detached, improve the purity of PVC material, it is ensured that final products quality。
