Description

Technical Field

[0001] This utility model relates to the field of PVC powder conveying technology, specifically to an automatic PVC powder feeding device. Background Technology

[0002] PVC powder feeding devices are industrial equipment used for automatic conveying of PVC powder. They are mainly used in plastic processing production lines and convey the powder to hoppers or injection molding machines through the principle of vacuum negative pressure.

[0003] Existing material suction devices require the use of vacuum pumps and feed pipes to suck up powder from the storage area. However, this process has certain drawbacks. When using a vacuum pump to suck up material, the feed pipe needs to start sucking from the outermost layer of the powder. However, this suction method makes it difficult to simultaneously suck up the remaining material on the inner wall of the storage device. At the same time, due to environmental factors, after the powder has accumulated for a long time, its interior will gradually harden, which will affect the efficiency of powder suction.

[0004] In view of this, an automatic PVC powder feeding device was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: An automatic PVC powder feeding device includes a storage mechanism and a feeding mechanism installed within the storage mechanism. The storage mechanism includes a silo with a slide rail on its inner wall and a scraper ring pad movably installed inside the silo. The feeding mechanism includes two load-bearing plates fixedly installed outside the silo. A shaft is movably installed on the top of the inner side of the two load-bearing plates, and a tensioning wheel is fixedly installed on the outside of the shaft. An end rod is movably installed on the bottom of the inner side of the two load-bearing plates, and an auxiliary wheel is fixedly installed on the outside of the end rod. A gear is fixedly installed on the outer end of the end rod. A protective outer tube is drivenly connected to the tensioning wheel and the auxiliary wheel. A feeding tube is installed inside the protective outer tube. The section of the feeding tube that penetrates into the inner cavity of the silo is fixedly installed on the scraper ring pad.

[0007] In a preferred embodiment, the present invention can be further configured such that: a control module is fixedly installed inside the silo, a motor is fixedly installed on the control module, and a stirring rod is fixedly installed on the transmission shaft inside the motor, the stirring rod being located in the middle of the silo cavity.

[0008] In a preferred embodiment, the present invention can be further configured such that: three equally spaced stirring elements are fixedly installed on the outside of the stirring rod, and the stirring elements are welded together from a ring and narrow blades.

[0009] In a preferred embodiment, the present invention can be further configured such that the top and bottom ends of the scraper ring pad are both provided with cutting edges.

[0010] In a preferred embodiment, the present invention can be further configured such that: two clamps are fixedly installed on the outer wall of the silo, and a driving component is movably installed in the two clamps; The driving component consists of a rotating wheel, a vertical rod, and an eccentric gear, with the eccentric gear meshing with the gear.

[0011] In a preferred embodiment, the present invention can be further configured such that a banana-shaped anti-slip washer is fitted onto the tensioning wheel.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model stores PVC powder in an extended and widened silo, and uses a protective outer pipe and a suction pipe to suck up the powder from the top of the silo. Combined with a stirring rod and multiple stirring components, the powder accumulated in the silo is loosened. After the external vacuum pump is connected to the suction pipe, the loosened powder can be efficiently sucked up, effectively increasing the single suction beam.

[0013] 2. This utility model improves the efficiency of removing residual material from the inner wall of the silo by fixing a scraper ring pad to the inner end of the suction tube. This is achieved by using an anti-slip outer tube to rotate at a constant speed along the inside of the slide, while the scraper ring pad scrapes material along the inner wall of the silo. This prevents excessive residual material from affecting the subsequent filling and storage of powder materials. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic PVC powder feeding device.

[0019] Example 1: Combination Figures 1 to 4 As shown, the present invention provides an automatic PVC powder feeding device, including a storage mechanism 100 and a feeding mechanism 200 installed in the storage mechanism 100. The storage mechanism 100 is used to store PVC powder, and the feeding mechanism 200 is used to efficiently suck out the powder stored in the storage mechanism 100.

[0020] The storage mechanism 100 includes a silo 110, the inner wall of which is provided with a slide rail 1101, and a scraper ring pad 150 is movably installed inside the silo 110. The suction mechanism 200 includes two load-bearing plates 210 fixedly installed on the outside of the silo 110. A shaft 220 is movably installed on the top of the inner side of the two load-bearing plates 210. A tensioning wheel 2201 is fixedly installed on the outside of the shaft 220. An end rod 230 is movably installed on the bottom of the inner side of the two load-bearing plates 210. An auxiliary wheel 2301 is fixedly installed on the outside of the end rod 230. A gear 2302 is fixedly installed on the outer end of the end rod 230. A protective outer tube 260 is connected to the tensioning wheel 2201 and the auxiliary wheel 2301. A suction tube 270 is installed inside the protective outer tube 260. Two clamps 240 are fixedly installed on the outer wall of the silo 110, and a driving component 250 is movably installed inside the two clamps 240; The drive unit 250 consists of a rotating wheel, a vertical rod, and an eccentric gear, and the eccentric gear is adapted to mesh with the gear 2302; The tensioner 2201 is fitted with a banana-shaped anti-slip washer; The section of the suction pipe 270 that extends into the inner cavity of the silo 110 is fixedly installed on the scraper ring pad 150.

[0021] PVC powder is stored in the inner cavity of silo 110 in advance and silo 110 is sealed with silo cover. When it is necessary to suck out the powder from the inner cavity of silo 110 under the sealed state, the drive component 250 is rotated until the drive component 250 drives the gear 2302, end rod 230 and auxiliary wheel 2301. Finally, the protective outer tube 260 will rotate at a constant speed along the outside of the auxiliary wheel 2301 and tension wheel 2201, and the inner end of the protective outer tube 260 will drive the scraper ring pad 150 to descend at a constant speed along the inner cavity of silo 110. Next, the vacuum pump is connected to the outer end of the suction pipe 270. As the vacuum pump runs, the suction pipe 270, together with the scraper ring pad 150, can continuously suck out the powder from the top of the inner cavity of the silo 110.

[0022] Example 2: Combination Figure 2 and Figure 4 As shown, based on Embodiment 1, a control module 120 is fixedly installed inside the silo 110, a motor 1201 is fixedly installed on the control module 120, and a stirring rod 130 is fixedly installed on the transmission shaft inside the motor 1201. The stirring rod 130 is located in the middle of the inner cavity of the silo 110. Three equally spaced stirring elements 140 are fixedly installed on the outside of the stirring rod 130. The stirring elements 140 are welded together from a ring and narrow blades. The scraper ring pad 150 has cutting edges at both the top and bottom.

[0023] Preferably, the narrow blades inside the agitator 140 are not in contact with the inner wall of the scraper ring pad 150, the bottom end of the agitator 130 is mounted at the bottom of the inner cavity of the silo 110 via a bearing, and a sealing gasket is provided at the bottom of the agitator 130 to provide spill protection for the powder at the bottom of the inner cavity of the silo 110. As the motor 1201 starts and runs, the driven stirring rod 130 will drive the three stirring components 140 to loosen the accumulated powder. Together with the silo 110 and the silo cover to protect the powder, it can not only avoid interference from environmental factors, but also enhance the efficiency of the scraper ring pad 150 in descending, and further improve the suction efficiency of the suction pipe 270 for the loosened powder.

[0024] The working principle and usage process of this utility model are as follows: PVC powder is pre-filled into the inner cavity of silo 110. At this time, the PVC powder filled into the inner cavity of silo 110 will be temporarily stored. When it is necessary to suck up the PVC powder inside silo 110; The drive component 250 is pre-installed until the deflection gear at the bottom of the drive component 250 drives the gear 2302, the end rod 230 and the auxiliary wheel 2301 until the auxiliary wheel 2301 drives the protective outer tube 260 to rotate counterclockwise until the end of the suction tube 270 that penetrates to the outside of the protective outer tube 260 rises at a constant speed. At this time, the inner end of the suction tube 270 will gradually descend towards the bottom of the inner cavity of the silo 110. At the same time, the end of the suction tube 270 that penetrates to the inner cavity of the silo 110 will drive the scraper ring pad 150 to descend along the inner wall of the silo 110. Next, the external suction pump is connected to the external pipe section of the suction pipe 270, and air is sucked out. The powder at the top layer of the inner cavity of the silo 110 can be continuously sucked out. In order to improve the low resistance of the scraper ring pad 150 descending along the inner wall of the silo 110, the motor 1201 is run until the transmission shaft inside the motor 1201 drives the stirring rod 130. At this time, the three stirring components 140 fixedly installed outside the stirring rod 130 will continuously loosen the powder inside the silo 110, thereby improving the efficiency of the scraper ring pad 150 descending.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
