Description

Technical Field

[0001] This utility model relates to the field of PVC technology, specifically to a PVC metering machine with anti-clogging and anti-jamming properties. Background Technology

[0002] PVC is a commonly used plastic material with characteristics such as corrosion resistance, wear resistance, and good insulation properties. In order to ensure its performance, additional production aids, including liquid and solid aids, need to be added during its production and processing. The amount added during the process is subject to requirements and needs to be determined according to the actual production situation. Generally, a metering machine is used for control.

[0003] Existing PVC metering machines mainly consist of a hopper and a weight sensor. First, production additives are added into the hopper. During the process, the weight sensor measures the total mass of the hopper and additives in real time. When the required mass is reached, feeding into the hopper stops, thus obtaining a quantitative amount of additives and achieving metered addition of additives. However, in actual use, especially for fixed additives, prolonged use can lead to material blockage at the discharge point, making it inconvenient to use.

[0004] Based on this, this utility model designs an anti-blocking and anti-jamming PVC metering machine to solve the above problems. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments.

[0031] In some embodiments, please refer to the accompanying drawings. Figure 1 , Figure 2 and Figure 3 A PVC metering machine with anti-clogging and anti-jamming features includes a metering hopper 1, a hopper cover 2 installed at the top of the metering hopper 1, a feed pipe 3 connected to the side wall of the metering hopper 1, an upper solenoid valve 4 installed at the connection between the feed pipe 3 and the metering hopper 1, a pressure ring plate 5 fixed to the bottom edge of the metering hopper 1, a discharge pipe 6 connected to the bottom of the metering hopper 1, a lower solenoid valve 7 installed at the connection between the discharge pipe 6 and the metering hopper 1, a bottom plate 8 at the bottom of the metering hopper 1, a through groove 9 at the center of the top of the bottom plate 8, through which the discharge pipe 6 passes, and an installation groove 1 at the top of the bottom plate 8. 0. A weight sensor 11 is installed in the mounting slot 10. An anti-blocking component is installed on the bucket cover 2.

[0032] In this embodiment of the utility model, when in use, the device is connected to an external feeding device through the feed pipe 3. When additional material needs to be added, the upper solenoid valve 4 is opened, and the material enters the metering hopper 1 through the feed pipe 3. As the material enters, the weight of the metering hopper 1 increases continuously. The weight sensor 11 monitors this in real time. When the addition amount is reached, the upper solenoid valve 4 is closed to stop the addition of material. At this time, the lower solenoid valve 7 is opened, and the material leaves the metering hopper 1 through the discharge pipe 6 and enters the subsequent external processing equipment. During the process, the electric lifting rod 15 runs, driving the disturbance rod 16 to move down and bring it close to the bottom of the inner wall of the metering hopper 1.

A suitable through hole 28 is selected, and the fixing rod 30 is inserted into the through hole 28 and the positioning hole 29 to fix the positioning plate 24, so that it contacts the side wall of the metering hopper 1 for auxiliary fixation. The device is then connected through the feed pipe 3. Connected to external feeding equipment, when additional materials are needed, the upper solenoid valve 4 opens, and the material enters the metering hopper 1 through the feed pipe 3. As the material enters, the weight of the metering hopper 1 increases continuously, and the weight sensor 11 monitors it in real time. When the addition amount is reached, the upper solenoid valve 4 closes to stop the addition of materials. At this time, the lower solenoid valve 7 opens, and the material leaves the metering hopper 1 through the discharge pipe 6 and enters the subsequent external processing equipment. During the process, the electric lifting rod 15 runs, driving the disturbance rod 16 to move down and bring it close to the bottom of the inner wall of the metering hopper 1. The rotating motor 13 drives it to rotate, assisting the material to be discharged and preventing blockage and jamming.
