For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0044] Reference Figures 1-8 For the first embodiment of the present application, a double-stirring dragon filling machine is proposed, which comprises a device main body 1, the device main body 1 has a feed inlet 101; the feed cylinder 2 is arranged on the device main body 1 and communicates with the feed inlet 101, the filling is fed into the device main body 1 through the feed cylinder 2; the mounting frame 3 is arranged on the feed cylinder 2; the rotating shaft 4 is rotatably arranged on the mounting frame 3, one end is located in the feed cylinder 2; the stirring rod 5 is arranged on the rotating shaft 4 and is used for stirring the filling.

[0045] In this embodiment, in order to solve the problem that the stuffing filling machine in the related art is prone to air chamber between the screw shafts due to uneven stuffing feeding during filling, leading to inaccurate filling flow, a double-stirring auger stuffing filling machine is designed. The feeding port 101 is located on one side of the top of the device main body 1, and the opening edge is rounded to avoid scratching the stuffing. The feeding cylinder 2 is welded on the device main body 1 to ensure that the stuffing can flow into the feeding port 101 by gravity in the feeding cylinder 2. The mounting frame 3 is frame-shaped and spans above the feeding cylinder 2 to provide stable support for the entire stirring system. The rotating shaft 4 passes through the mounting frame 3 at one end to realize rotation. The stirring rod 5 has multiple rods and is installed in a radial manner at one end of the rotating shaft 4 located in the feeding cylinder 2. The length of the stirring rod 5 is moderate, and it can stir the stuffing in all directions as the rotating shaft 4 rotates, preventing the stuffing from accumulating at the feeding port 101.

[0046] The advantage is that the stuffing is fully stirred by the stirring rod 5 before it enters the screw shaft, breaking the agglomerates that may form, allowing the stuffing to flow into the feeding port 101 with uniform texture, reducing the risk of air chamber due to uneven initial feeding, and improving the stability of the filling machine operation.

[0047] Further, the rotating shaft 4 is threadedly connected with the mounting frame 3, the rotating shaft 4 has a sliding groove 401, and further includes a gear 6. The gear 6 is rotatably arranged on the mounting frame 3 and is sleeved on the outside of the rotating shaft 4. The gear 6 has a limiting rod 601 which is slidably arranged in the sliding groove 401. After the gear 6 rotates, it drives the rotating shaft 4 to rotate and vertically slide relative to the mounting frame 3.

[0048] In this embodiment, the outer wall of the rotating shaft 4 has external threads, and the inner wall of the through hole on the mounting frame 3 has internal threads. The precise fit of the internal and external threads achieves threaded connection. A straight groove is formed on the rotating shaft 4 as the sliding groove 401. The gear 6 is rotatably installed on the mounting frame 3 through a recess and is sleeved on the outside of the rotating shaft 4. The limiting rod 601 of the gear 6 is cylindrical and smooth, and is precisely connected in the sliding groove 401. When the motor drives the gear 6 to rotate, the rotating shaft 4 rotates and stably vertically lifts due to the cooperation of the threads and the limiting rod 601, changing the stirring depth and range.

[0049] The advantage is that this dynamic stirring structure design allows the rotating shaft 4 to stir the stuffing at different heights, which can more effectively address the layering and accumulation of the stuffing during the feeding process compared to fixed position stirring, further promoting uniform distribution of the stuffing and greatly reducing the possibility of air chamber in the screw shaft area due to uneven local pressure, ensuring the accuracy and stability of the filling flow and improving the adaptability of the filling machine to different states of the stuffing.

[0050] Further, the cleaning rod 7 is arranged on the rotating shaft 4, and the cleaning rod 7 is provided with a cleaning scraper 701 abutting against the inner wall of the feeding cylinder 2. After the rotating shaft 4 rotates and vertically slides, the cleaning scraper 701 gradually cleans the inner wall of the feeding cylinder 2.

[0051] In the embodiment, one end of the cleaning rod 7 is fixed on the rotating shaft 4 in an embedded structure and extends radially outward. The cleaning scraper 701 is made of soft rubber and is in a strip shape and is fixed at the end of the cleaning rod 7. When the rotating shaft 4 rotates and vertically slides, the cleaning scraper 701 always adheres to the inner wall of the feeding cylinder 2, and with the movement of the rotating shaft 4, the adhered stuffing is gradually scraped off and mixed into the stuffing again.

[0052] The combination of the cleaning rod 7 and the cleaning scraper 701 can clean the residual stuffing on the inner wall of the feeding cylinder 2 in real time, avoid the influence of the residual stuffing on the quality of subsequent products, prevent the residual accumulation from changing the effective inner diameter of the feeding cylinder 2, maintain a stable feeding rate, and prevent the uneven feeding or the jamming caused by the residual stuffing on the inner wall.

[0053] Further, the cleaning rod 7 is arranged on the rotating shaft 4, and the cleaning rod 7 is provided with a cleaning scraper 701 abutting against the inner wall of the feeding cylinder 2. After the rotating shaft 4 rotates and vertically slides, the cleaning scraper 701 gradually cleans the inner wall of the feeding cylinder 2.

[0054] In the embodiment, a plurality of cleaning rods 7 are circumferentially distributed. Compared with a single cleaning rod 7 or a small number of cleaning rods 7, the cleaning rods 7 can realize omnidirectional cleaning without dead angle, greatly improve the cleaning efficiency, ensure that the inner wall of the feeding cylinder 2 is always clean, keep the stuffing at a uniform flow rate during the whole feeding process, effectively prevent the feeding fluctuation caused by local residual, provide continuous and stable conditions for precise filling, and enhance the overall performance of the filling machine.

[0055] Further, the opening diameter of the feeding cylinder 2 away from the device main body 1 is greater than the opening diameter of the feeding cylinder 2 close to the device main body 1.

[0056] In the embodiment, the feeding cylinder 2 is designed to be tapered with the upper part being wide and the lower part being narrow. The outer wall of the feeding cylinder 2 is provided with a reinforcing rib to enhance the overall strength, and the inner wall is finely polished to be extremely smooth, thereby reducing the flow resistance of the stuffing and ensuring that the stuffing flows to the device main body 1 under the action of gravity at a high speed and uniformly.

[0057] The tapered feeding cylinder 2 in combination with the design of the feeding hopper conforms to the principle of material flow mechanics, accelerates the feeding speed, reduces the risk of blockage, and simultaneously utilizes the gathering and compression effect of the tapered structure on the stuffing, so that the stuffing is more compact and uniform before entering the spiral shaft, effectively inhibits the formation of air chambers, and improves the stability of the filling flow.

[0058] Further, the cleaning rod 7 is arranged through and slidingly on the rotating shaft 4, a plurality of cleaning rods 7 are vertically spaced along the axis of the rotating shaft 4, and further comprising a first elastic member 8, the first elastic member 8 is sleeved on the cleaning rod 7, and the two ends of the first elastic member 8 act on the cleaning rod 7 and the rotating shaft 4 respectively, for providing a force for the cleaning scraper 701 to approach the inner wall of the feeding cylinder 2.

[0059] In the embodiment, the cleaning rod 7 is transversely sliding on the rotating shaft 4, and two cleaning rods 7 are vertically spaced along the rotating shaft 4, and a spiral spring is arranged between the cleaning rod 7 and the rotating shaft 4 as the first elastic member 8, the two ends of the first elastic member 8 are respectively clamped in the corresponding clamping grooves of the cleaning rod 7 and the rotating shaft 4, and there are rubber pads in the clamping grooves to prevent the spring from being worn.

[0060] When the cleaning scraper 701 moves to the lower half of the feeding cylinder 2, the cleaning rod 7 will gradually slide transversely due to the shape of the feeding cylinder 2, and when the rotating shaft 4 slides vertically upward, the first elastic member 8 automatically contracts to drive the cleaning rod 7 to slide reversely, so that the cleaning scraper 701 always abuts against the inner wall of the feeding cylinder 2 to maintain a good cleaning state.

[0061] Further, the cleaning scraper 701 has a cleaning surface 702, and the cleaning surface 702 forms an included angle with the vertical surface.

[0062] In the embodiment, the side of the cleaning scraper 701 close to the feeding port is the cleaning surface 702, and the included angle between the cleaning surface 702 and the vertical surface is about 45 degrees, and the shape of the cleaning surface 702 is consistent with the curvature of the inner wall of the feeding cylinder 2. When the rotating shaft 4 drives the scraper to rotate, the inclined cleaning surface 702 can not only scrape off the filling material, but also push the scraped filling material downward along the inclined surface to make it quickly return to the filling material flow, thereby avoiding secondary accumulation.

[0063] The advantage is that the design of the inclined cleaning surface 702 optimizes the function of the cleaning scraper 701, improves the cleaning efficiency, and ensures that the scraped filling material participates in the subsequent filling in time.

[0064] Further, the rotating shaft 4 has a cavity 402, the cleaning rod 7 has a clamping hole 703, and further comprising a clamping rod 9, a plurality of clamping rods 9 are vertically slidingly arranged in the clamping hole 703, and after the clamping rod 9 slides vertically, the clamping rod 9 extends out of the clamping hole 703 into the cavity 402, for limiting the position of the cleaning rod 7 and the rotating shaft 4.

[0065] In this embodiment, a cylindrical cavity 402 is formed in the shaft 4 along the axial direction, and the inner wall of the cavity 402 is smooth. The cleaning rod 7 is provided with a matched clamping hole 703 near the shaft 4, and the inner wall of the clamping hole 703 has a magnetic force. The clamping rod 9 vertically slides in the clamping hole 703, and the top of the clamping rod 9 is spherical to facilitate sliding in the cavity 402. When it is necessary to fix the cleaning rod 7, the clamping rod 9 is pushed upward, and the top of the clamping rod 9 is clamped into the cavity 402, thereby achieving rigid connection of the cleaning rod 7 and the shaft 4 and limiting the position of the cleaning rod 7 and the shaft 4.

[0066] The clamping hole 703 has a magnetic force, so that when the cleaning rod 7 slides laterally, the clamping rod 9 will not fall out of the clamping hole 703. The cooperation of the clamping rod 9 and the cavity 402 provides a reliable locking mechanism for the cleaning rod 7. When the filling machine is transported, stored or does not need the cleaning function, the cleaning rod 7 is ensured to be stable and immovable, avoiding damage to the parts due to factors such as collision and vibration, thereby enhancing the reliability and durability of the filling machine and facilitating management and operation under different working conditions.

[0067] Further, a top rod 10 is vertically slidably arranged in the cavity 402, and one end of the top rod 10 extends into the feeding cylinder 2. The top rod 10 abuts against the clamping rod 9 after vertically sliding upward, and pushes the clamping rod 9 to extend into the cavity 402. A second elastic member 11 is sleeved on the top rod 10, and the two ends of the second elastic member 11 act on the top rod 10 and the shaft 4 respectively, thereby providing a force for the top rod 10 to vertically slide in the cavity 402.

[0068] In this embodiment, the top rod 10 is vertically and accurately installed in the circular cavity 402 of the shaft 4, the top of the top rod 10 extends out of the cavity 402 and is polished into a smooth round corner, and the top rod 10 extends into the feeding cylinder 2. A protective shell is arranged at the bottom of the shaft 4 to avoid contact between the top rod 10 and the filling in the feeding cylinder 2. The second elastic member 11 is a spiral spring, which is sleeved on the lower part of the top rod 10, one end of the second elastic member 11 is connected to the circular connecting plate of the top rod 10, and the other end is stably pressed against the bottom surface of the shaft 4. During the normal working stage of the filling machine, only the shaft 4 rotates and the vertical sliding of the shaft 4 promotes the stirring of the filling by the stirring rod 5. Under the action of the elastic force of the second elastic member 11, the top rod 10 is stably kept at the initial high position, the clamping rod 9 is respectively arranged at the cavity 402 and the clamping hole 703, and the position of the cleaning rod 7 is locked, so that the cleaning rod 7 does not participate in the work. When the filling is completed and the inner wall of the feeding cylinder 2 needs to be cleaned, the top rod 10 is vertically slid downward, the clamping rod 9 vertically slides downward and is separated from the cavity 402 under the action of gravity, and the cleaning rod 7 is instantaneously unlocked, thereby preparing for the subsequent cleaning process. The whole operation is convenient and efficient, and does not need complex tools.

[0069] The top rod 10 and the second elastic member 11 constitute a clever unlocking device, which closely meets the working process requirements of the filling machine. During daily operation, the cleaning rod 7 is reliably locked to avoid equipment failure or affect the filling accuracy caused by misoperation.

[0070] Further, the cavity 402 is in communication with the chute 401, and the push rod 12 is vertically slidably arranged in the cavity 402 and extends into the chute 401, and after the rotating shaft 4 rotates and vertically slides, the limiting rod 601 abuts against one end of the push rod 12, so that the push rod 12 vertically slides downward in the cavity 402, and the clamping rod 9 is pushed to vertically slide downward, and the position restriction of the cleaning rod 7 and the rotating shaft 4 is released.

[0071] In the embodiment, the cavity 402 is in communication with the chute 401 when the rotating shaft 4 rotates, so as to ensure smooth sliding of the push rod 12. The push rod 12 is vertically slidably arranged in the cavity 402 and extends into the chute 401. When the filling machine is in a normal filling state, the rotating shaft 4 rotates and vertically slides to drive the limiting rod 601 to move in the chute 401, at this time, the push rod 12 is not disturbed by external force, the clamping rod 9 maintains the locking state of the cleaning rod 7 and the rotating shaft 4, and the cleaning rod 7 is away from the inner wall of the feeding cylinder 2. Once the filling is completed, the rotating shaft 4 vertically slides to the limit position under the action of the driving mechanism, at this time, the limiting rod 601 abuts against the top of the push rod 12 in the chute 401, the push rod 12 rapidly vertically slides downward under the force, the bottom of the push rod 12 pushes the clamping rod 9 to move downward, the position restriction of the cleaning rod 7 and the rotating shaft 4 is released, and the cleaning process is activated synchronously. In the subsequent cleaning process, as the rotating shaft 4 rotates and vertically slides under the driving of the driving member, the cleaning scraper 701 closely adheres to the inner wall of the feeding cylinder 2 under the elastic force of the first elastic member 8, and the residual stuffing is cleaned from the top to the bottom. When the cleaning rod 7 reaches the bottom of the feeding cylinder 2, the clamping hole 703 coincides with the cavity 402, at this time, the top rod 10 vertically slides upward under the elastic force of the second elastic member 11, the one end of the clamping rod 9 is pushed to smoothly enter the cavity 402, the relative position of the cleaning rod 7 and the rotating shaft 4 is stably limited again, and the complete cleaning and resetting process is completed. The whole process is highly automatic, and the components are accurately and accurately coordinated.
