[0005] Preferably, the scraping guide plate is positioned so that its height relative to the bottom of the inner side of the storage tank decreases from one end near the inner wall of the storage tank to the other end near the central axis of the storage tank, in order to guide the scraped filling material to flow towards the lower center of the inner side of the storage tank.

This not only ensures the uniformity of the raw materials and improves filling quality, but also plays a crucial role in the cleaning process, effectively removing residual raw materials from the bottom and side walls of the tank. The entire cleaning process can be completed simply by rinsing with water, greatly simplifying the operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Filling machines are a small category of packaging machines. From the perspective of the materials being packaged, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines. Automatic filling machines are widely used in various industries such as daily chemicals and oils, and can fill different high-viscosity fluids. However, splashing is inevitable during operation, soiling the worktable. After the work is completed, raw materials may remain in the storage tank, making cleaning the tank troublesome. Please refer to... Figures 1-3 This embodiment provides a filling machine with a self-cleaning function, solving the technical problem of the cumbersome and lengthy cleaning process of the filling machine. The device includes a filling platform 1 as a supporting base. A storage tank 2 for storing filling raw materials is set on the top of the filling platform 1 via a bracket. A filling pump 3 for discharging materials from the storage tank 2 is installed at the bottom of the storage tank 2. A bidirectional lead screw 4 is rotatably connected to the middle of the top of the storage tank 2. A drive motor 9 is installed on one side of the top of the storage tank 2. The drive end of the drive motor 9 is connected to a drive gear 10. A driven gear 11 that meshes with the drive gear 10 is fixedly connected to the lower outer side of the bidirectional lead screw 4. A support threaded sleeve 5 is helically connected to the outer side of the bidirectional lead screw 4. An extension support frame 6 is rotatably connected to the outer side of the support threaded sleeve 5. Push-pull slide rods 7 are fixedly connected to the bottom of both sides of the extension support frame 6. A scraping guide plate 8 for cleaning raw materials adhering to the inner wall of the storage tank 2 is fixedly connected to the bottom of the push-pull slide rods 7. Two feed ports 15 are connected to one side of the top of the storage tank 2, and the two feed ports 15 are respectively connected to the external raw material feed pipe and water injection pipe.

[0021] During operation, raw materials are injected into storage tank 2 through inlet 15, and the filling pump 3 extracts the raw materials from storage tank 2 to achieve filling. During filling, the fluidity of the raw materials inside storage tank 2 will decrease, which may cause the raw materials at the top of storage tank 2 to undergo a sedimentation reaction, causing the water inside to separate from the paste-like raw materials, thus affecting the quality of the final filled raw material product. Therefore, when the filling operation starts, the operator starts the drive motor 9. At that time, the drive motor 9 will drive the scraper guide plate 8 to move up and down reciprocally through the meshing drive gear 10 and driven gear 11, thereby agitating the raw materials inside storage tank 2 and keeping them in a completely mixed state. In the later cleaning process, the up and down scraping can clean the raw material residue on the inner wall of storage tank 2, thereby reducing the difficulty of later cleaning.

[0022] The scraping guide plate 8 gradually decreases in height relative to the bottom of the inner side of the storage tank 2 from one end near the inner wall of the storage tank 2 to the other end near the central axis of the storage tank 2, and is used to guide the scraped filling material to flow towards the lower middle of the inner side of the storage tank 2.

[0023] A stirring tube 12 is rotatably connected to the bottom end of a bidirectional screw 4 at the top center of the inner side of the storage tank 2. Several stirring impellers 13 are fixedly connected to the bottom end of the stirring tube 12. A drag-reducing rubber sheet 14 is fixedly connected to the bottom outer side of the stirring impellers 13 to reduce friction between the stirring impellers 13 and the inner wall of the storage tank 2.

[0024] The top end of the drag-reducing rubber sheet 14, which is close to the inner wall of the storage tank 2, is attached to the bottom end of the scraping guide plate 8.

[0025] Furthermore, during the rotation of the drive motor 9, the stirring tube 12 connected to the bottom of the bidirectional lead screw 4 can also drive the stirring impeller 13 to rotate, which can more fully stir the raw materials inside the storage tank 2. At the same time, it can also clean the bottom and lower inner wall of the storage tank 2 during cleaning, making the cleaning operation simpler and easier. It is only necessary to pour water into the storage tank 2 through one of the two feed ports 15 for simple rinsing.

[0026] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
