Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that after the semi-molten semi-finished product is formed, it is impossible to check whether it is damaged, resulting in the formation of defective products after the semi-molten semi-finished product is processed by mold blow molding. At this time, it is necessary to manually check whether the finished product is intact and the heating mechanism During operation, part of the heat will overflow, but the overflowed part of the heat cannot be effectively used, resulting in the problem of waste of heat energy, providing a high-precision vertical blow molding machine injection system

Embodiment 1

[0049] As a preferred embodiment of the present invention: the driving mechanism includes a motor, a reduction box and a screw, the motor is rotationally connected to the reduction box through a rotating shaft, the reduction box is rotationally connected to the screw through a rotating shaft, and the screw is located at the center of the barrel;

[0050] When the granular raw material enters the device, the motor drives the screw to rotate through the reducer. At this time, the reducer decelerates the output speed of the motor and then drives the screw to rotate. When the screw rotates, the granular raw material is extruded. The heat of the granular raw material is heated once, and the role of the screw in this process is to control the entering speed of the raw material and control its falling speed to keep the falling speed of the raw material within a reasonable range.

Embodiment 2

[0052] As a preferred embodiment of the present invention: the heating module is arranged on the outside of the barrel, and the heating module is in contact with the inside of the barrel through a heat conduction plate, the heat conduction plate penetrates to the inner wall of the barrel and is flush with the inner wall of the barrel, and the heating module There is an insulation cover on the outside;

[0053] The heating module is set outside the machine barrel to prevent the semi-molten raw material from contacting the heating module. When the heating module heats the raw material, the heat emitted by the heating module is introduced into the device through the heat conduction plate, thereby melting the raw material. Set on the outside of the heating module, it can effectively prevent the direct loss of the heat emitted by the heating module, so that the heat can be better preserved.

Embodiment 3

[0055] As a preferred embodiment of the present invention: the top of the feeding module is provided with an automatic feeding machine, the automatic feeding machine includes a conveyor belt and a material guide plate, and the material guide plate is connected to the input end of the feeding module;

[0056] Automatic feeding can enable the device to continuously replenish raw materials, reducing the steps of manual feeding, and the automatic feeding process can be set to add a predetermined amount within a predetermined time, thereby improving the quality of feeding. Compared with the manual feeding process, automatic feeding has advantages Protruding, suitable for machinery running for a long time.

Abstract

The invention discloses a high-accuracy vertical blow molding machine injection system, and relates to the field of blow molding machines. The system comprises a driving mechanism, a heating module, amaterial adding module, a machine barrel and a machine head module, wherein the driving mechanism is used for extruding raw materials to enable molten raw materials to downwards move; the heating module is used for heating particle raw materials to enable the particle raw materials to become a plastic liquid under a half-molten state; the material adding module is used for conveying the particleraw materials into the heating module; the machine barrel is used for cooperating with the driving mechanism to enable half-molten raw materials to downwards move; and the machine head module is usedfor carrying out primary processing on a half-molten hollow thin film. The high-accuracy vertical blow molding machine injection system is provided with a scanning mechanism and a receiving mechanism,so that the cylindrical hollow plastic thin film can be scanned, an infrared ray reflects when meeting plastic and reflects when meeting the inner wall of the machine barrel, and the wavelengths of reflecting waves are different; after an infrared receiver receives an infrared signal, the infrared signal enters an operational circuit to be calculated, then, the calculated infrared signal is fed back to a PLC (Programmable Logic Controller), the PLC can determines whether an alarm needs to give an alarm or not according to a category of electric signals, and an early warning function of the injection system is improved.

Description

technical field [0001] The invention relates to the field of blow molding machines, in particular to a high-precision vertical blow molding machine injection system. Background technique [0002] After the liquid plastic is sprayed out, the plastic body is blown and attached to a mold cavity of a certain shape by using the wind blown by the machine to make a product. This machine is called a blow molding machine. The plastic is melted and blown in the screw extruder. Quantitative extrusion, and then molded through the mouth film, and then cooled by the wind ring, and then pulled by a tractor at a certain speed, and wound by a winding machine into a roll. [0003] However, the current injection system for blow molding machines cannot check whether the semi-molten semi-finished product is damaged after it is molded, resulting in defective products after the semi-molten semi-finished product is processed by mold blow molding. At this time, it is necessary to manually check whet...
