[0002] In the food processing industry, jam filling is a crucial production step. Currently used jam filling equipment is prone to clogging and accumulation in the feed pipes, filling valves, and filling heads during the filling process due to the high viscosity of jam and the presence of fruit pieces and other solid particles in some jams. This not only causes interruptions in the filling process, requiring frequent shutdowns for cleaning and severely impacting production efficiency, but also risks contaminating the jam during cleaning, reducing product quality, and resulting in significant economic losses for the company.

[0003] A search revealed that Chinese Patent Publication No. CN221542051U discloses an automatic mixing and filling machine for sauces, which includes a machine body, a cleaning structure and a lifting assembly; a mixing cylinder is fixedly mounted on the surface of the machine body, a filling valve is installed on the outside of the mixing cylinder, and the top of the mixing cylinder is in contact with a support plate.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: Existing jams contain high viscosity and fruit particles, leading to easy clogging of the filling head during the filling process. This application addresses the technical problem of easy clogging of the filling head due to the high viscosity and fruit particles of existing jams by incorporating a screw conveyor for stirring and pushing, a grinding space formed by a first rotating disc and a scraper ring to break up clumps, and a scraper ring to clean the inner wall of the discharge pipe.

[0019] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] This application discloses a jam filling device with an anti-clogging structure. For example... Figure 1 As shown, the device includes a frame 1, which serves as the mounting base for the entire device and supports various functional components. A first funnel 2 is fixedly installed on the frame 1. The first funnel 2 has a hollow conical structure, with its upper end being the feed inlet for receiving jam to be filled and its lower end being the discharge outlet for conveying the jam downwards.

[0021] A motor 3 is fixedly mounted on the frame 1 via a motor mount. The motor 3 is a servo motor, and its output shaft extends vertically downward and is coaxially mounted with the first funnel 2. The end of the output shaft of the motor 3 is coaxially fixedly connected to an auger 4 via a coupling. The auger 4 is located in the inner cavity of the first funnel 2 and has a gap with the inner wall of the first funnel 2. When the motor 3 is started, the auger 4 rotates synchronously with the output shaft, which can stir the jam in the first funnel 2, prevent the jam from accumulating, and push the jam to the discharge port of the first funnel 2.

[0022] A second funnel 5 is provided below the discharge port of the first funnel 2. The second funnel 5 is also a hollow conical structure, and its inlet is directly opposite the discharge port of the first funnel 2. Vertical slide rails 6 are fixedly provided on the frame 1 on both sides corresponding to the second funnel 5. The outer wall of the second funnel 5 is slidably connected to the slide rails 6 through a slider, so as to realize the vertical sliding cooperation between the second funnel 5 and the frame 1.

[0023] A first linear actuator 7 is also fixedly installed on the frame 1. The first linear actuator 7 is an electric push rod or a cylinder. Its output end extends vertically upward and is fixedly connected to the outer wall of the second funnel 5. By controlling the extension and retraction of the first linear actuator 7, the second funnel 5 can be driven to slide up and down along the slide rail 6. The discharge port of the second funnel 5 is connected to the discharge pipe 8 via a flange. The discharge pipe 8 is a vertically arranged circular pipe structure with a filling port at its lower end. A cover plate 9 is fitted on the outer wall of the discharge pipe 8. The inner wall of the cover plate 9 and the outer wall of the discharge pipe 8 are connected by a vertical sliding groove and a slider to achieve a vertical sliding connection between the cover plate 9 and the discharge pipe 8. A first compression spring 10 is also welded to the upper end face of the cover plate 9. The first compression spring 10 is fitted on the outside of the discharge pipe 8, and its upper end is welded and fixed to the lower end face of the second funnel 5.

[0024] The lower end face of the auger 4 is provided with a vertical sliding hole, and a first sliding rod 11 is inserted through the sliding hole. The first sliding rod 11 is clearance-fitted with the sliding hole to realize the vertical sliding connection between the two. The lower end of the first sliding rod 11 extends downward, passes through the second funnel 5 and extends into the inner cavity of the discharge pipe 8. A first rotating disk 12 is coaxially fixed on its lower end face. The first rotating disk 12 is an inverted frustum-shaped structure (i.e., wider at the top and narrower at the bottom). Its sidewalls are roughened to form a first grinding surface 121. Fine ridges can be provided on the first grinding surface 121 to enhance the grinding effect. When the auger 4 rotates, it is connected to the first sliding rod 11 through a key through a sliding hole, which can drive the first sliding rod 11 and the first rotating disk 12 to rotate synchronously. The side wall of the discharge pipe 8 is provided with a first through groove 81, which extends along the axial direction of the discharge pipe 8; a sealing plate 13 is welded to the inner wall of the cover plate 9 at the position corresponding to the first through groove 81. The length and width of the sealing plate 13 are both larger than the specifications of the first through groove 81, which can completely cover and seal the first through groove 81 to prevent jam from leaking from the first through groove 81. A first connecting part 14 is welded to the side of the sealing plate 13 away from the cover plate 9. A bearing 15 is fixedly embedded in the first connecting part 14. The outer ring of the bearing 15 is interference-fitted with the inner wall of the first connecting part 14, and the inner ring is interference-fitted with the outer wall of the first sliding rod 11. With the setting of the bearing 15, the first sliding rod 11 can rotate freely relative to the sealing plate 13. At the same time, when the cover plate 9 slides up and down, the first sliding rod 11 can be driven to slide up and down synchronously through the first connecting part 14 and the bearing 15. The lower end of the sealing plate 13 is also welded with a second connecting part 16, and the end of the second connecting part 16 is welded with a scraper ring 17. The scraper ring 17 is a circular ring structure, and its outer wall is tightly fitted with the inner wall of the discharge pipe 8. It can scrape off the jam attached to the inner wall of the discharge pipe 8 when it slides up and down with the cover plate 9. The upper end surface of the scraper ring 17 is an inclined first slope 171, and an annular grinding space 18 is formed between the first slope 171 and the first grinding surface 121 of the first rotating disk 12. A second grinding block 172 is also fixedly installed on the first slope 171. The second grinding block 172 is a uniformly distributed protrusion, which further enhances the grinding effect.

[0025] Working principle: The jam to be filled is added from the feed inlet of the first funnel 2; When filling is required, the first linear actuator 7 drives the second funnel 5 to move the discharge pipe 8 downward, so that the lower end face of the discharge pipe 8 is close to the bottom of the filling bottle. At this time, the scraper ring 17 and the discharge pipe 8 undergo an upward relative displacement, and scrape off the jam on the inner wall of the discharge pipe 8. Motor 3 drives auger 4 to rotate, auger 4 stirs the jam and pushes it to the discharge port of first funnel 2. The jam enters second funnel 5 through the discharge port of first funnel 2 and then flows into discharge pipe 8. At this time, the first linear actuator 7 drives the second funnel 5 to move the discharge pipe 8 upwards, so that the jam is filled more evenly. When the second funnel 5 moves upward, the cover plate 9 moves downward under the elastic force of the first compression spring 10, and the scraper ring 17 moves downward to scrape off the jam on the inner wall of the discharge pipe 8. During this process, the auger 4 drives the first sliding rod 11 and the first rotating disk 12 to rotate continuously. The first grinding surface 121 of the first rotating disk 12 and the first inclined surface 171 of the scraper ring 17 (and the second grinding block 172) rotate relative to each other in the grinding space 18, grinding and breaking up the lumps or large fruit particles contained in the jam that enter the grinding space 18, so as to avoid clogging the filling port of the discharge pipe 8.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
