Description

Technical Field

[0001] This utility model relates to the technical field of material suction machines, and in particular to an automatic material suction machine. Background Technology

[0002] Plastics are polymeric materials primarily made from synthetic resins. Through processing and molding, they are transformed into solid materials with specific shapes and functions, possessing excellent physical and chemical properties such as insulation, corrosion resistance, and wear resistance. Plastics are mainly composed of synthetic resins, additives, and other auxiliary materials. Among these, resin is the primary component of plastics and plays a major role in determining the performance of plastics and their products.

[0003] Currently, in plastic processing, plastic needs to be transported to injection molding machines or other equipment. The most common method is to use a material suction machine to transport plastics and various additives. The working principle of a plastic material suction machine is mainly based on the principle of vacuum negative pressure. It typically consists of a vacuum pump, a suction pipe, and a material tank. When the material suction machine is started, the vacuum pump begins to operate, generating vacuum suction. One end of the suction pipe is connected to the raw material storage container, and the other end leads to the material tank. Under the action of vacuum suction, the plastic raw material is quickly sucked from the storage container into the suction pipe and then into the material tank. Currently, to prevent plastic raw material from being sucked into the vacuum pump, a filter screen is usually installed inside the material tank to block the plastic. However, after long-term use, the material tank needs to be disassembled to clean the filter screen to prevent clogging, which is quite troublesome. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] This utility model discloses an automatic feeding machine, such as... Figure 1-4 As shown, the device includes a material cylinder 1, with a feed inlet 11 connected to its side wall. The feed inlet 11 is connected to a suction pipe. A discharge outlet is located at the bottom of the material cylinder 1, used to connect to other equipment. The top of the material cylinder 1 is open, and a top cover 2 is provided on the top. One side of the top cover 2 is hinged to the side wall of the material cylinder 1, and a hook is fixedly installed on the other side of the top cover 2. A fastener is fixedly installed on the outer side wall of the material cylinder 1, and the fastener engages with the hook. A suction port 23 is connected to the top cover 2 and is connected to a vacuum pump. When material needs to be sucked in, the suction pipe is inserted into the plastic raw material, and the vacuum pump operates to create a vacuum inside the material cylinder 1. Then, the plastic is sucked into the material cylinder 1 under air pressure. Simultaneously, to improve the sealing between the top cover 2 and the top of the material cylinder 1, a rubber sealing ring is provided between the top cover 2 and the top of the material cylinder 1.

[0025] In addition, a filter screen 3 is installed inside the feed cylinder 1, located above the feed inlet 11. The filter screen 3 is equipped with a fixing ring 31, and the edge of the filter screen 3 is fixedly connected to the inner wall of the fixing ring 31. An annular groove 12 is formed on the top inner wall of the feed cylinder 1, and the fixing ring 31 is inserted into the annular groove 12. After the operator inserts the fixing ring into the annular groove 12, the top cover 2 is closed to fix the filter screen 3. At the same time, a support net 32 ​​is installed inside the fixing ring 31, and the edge of the support net 32 ​​is fixedly connected to the inner wall of the fixing ring 31. The upper surface of the filter screen 3 is attached to the lower surface of the support net 32. The support net 32 ​​can support the filter screen 3, making the filter screen 3 less prone to deformation.

[0026] In addition, a scraper 4 is provided on the lower surface of the filter screen 3. The scraper 4 is in contact with the lower surface of the filter screen 3 and slides with the lower surface of the filter screen 3. A rotating shaft 21 is provided on the top cover 2 along the axial direction of the top cover 2. The top end of the rotating shaft 21 is rotatably supported on the top cover 2, and the bottom end of the rotating shaft 21 movably passes through the support net 32 ​​and is connected to the filter screen 3 and the scraper 4. A driving component for driving the scraper 4 to rotate is provided on the top cover 2. Specifically, the driving component includes a drive motor 22 fixedly installed on the top cover 2 along the axial length of the rotating shaft 21. The output shaft of the drive motor 22 is coaxially fixedly connected to the rotating shaft 21. When the drive motor 22 is working, it drives the rotating shaft 21 and the scraper 4 to rotate. The scraper 4 scrapes off the raw material adsorbed on the filter screen 3, so that the filter screen 3 is not easily clogged.

[0027] In addition, the bottom circumferential surface of the rotating shaft 21 is threaded, and a threaded sleeve 41 is welded to one end of the scraper 4. The threaded sleeve 41 is threadedly connected to the rotating shaft 21. The operator can remove the scraper 4 and the filter screen 3 from the rotating shaft 21 by unscrewing the threaded sleeve 41. Furthermore, a limit nut 211 is threaded on the rotating shaft 21, and the threaded sleeve 41 abuts against the lower surface of the limit nut 211. The limit nut 211 restricts the position of the threaded sleeve 41, ensuring that the scraper 4 makes just contact with the surface of the filter screen 3. Additionally, a fixing nut 212 is threaded on the rotating shaft 21, abutting against the lower surface of the threaded sleeve 41. The fixing nut 212 improves the stability of the connection between the threaded sleeve 41 and the rotating shaft 21, making it less likely for the scraper 4 to fall off.

[0028] The implementation principle of the automatic feeding machine in this embodiment of the utility model is as follows: the vacuum pump works to suck plastic into the material cylinder 1. When the raw material in the plastic is adsorbed onto the filter screen 3 under the action of air pressure, the drive motor 22 works to drive the rotating shaft 21 and the scraper 4 to rotate. The scraper 4 scrapes off the raw material adsorbed on the filter screen 3, so that the filter screen 3 is not easily blocked, and there is no need for operators to frequently disassemble and clean it. The degree of automation is higher and it is more convenient.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
