[0046] Combine Figures 1 to 9 As shown, according to a specific embodiment of the present application, a feeding device for sauce is provided.

[0047] Specifically, the feeding device includes: a box body 10 and a spiral conveying mechanism 20. The box body 10 has a accommodating chamber 11 and a discharge port 12. The spiral conveying mechanism 20 is arranged in the accommodating chamber 11. A material space is formed between the spiral conveying mechanism 20 and the side wall of the accommodating chamber 11. The discharge port 12 is connected to the material space. The spiral conveying mechanism 20 has a working state of rotating around its own central axis to transport the material in the material space to the discharge port 12 along the axial direction of the spiral conveying mechanism 20. The discharge port 12 is protrudingly arranged on a side wall of the box body 10. A discharge channel is formed inside the discharge port 12. The spiral conveying mechanism 20 includes a discharge section 100 located in the discharge channel. The number of spiral coils on the discharge section 100 is A. The inter-tooth gap formed by adjacent spiral teeth on the discharge section 100 has a projected area S along the height direction of the box body 10. B=S / A, and B≤40. The number of spiral coils is equal to Figure 6 The length D of the discharge section 100 shown in FIG is divided by the pitch P. The projected area S is Figure 7 Shown in.

[0048] In an embodiment of the present application, the sauce feeding device includes a box body 10 and a spiral conveying mechanism 20. The box body 10 has a accommodating chamber 11 and a discharge port 12. The spiral conveying mechanism 20 is arranged in the accommodating chamber 11, and a material space is formed between the spiral conveying mechanism 20 and the side wall of the accommodating chamber 11. The discharge port 12 is connected to the material space. The spiral conveying mechanism 20 has a working state of rotating around its own central axis to transport the material in the material space to the discharge port 12 along the axial direction of the spiral conveying mechanism 20. The screw 23 in the spiral conveying mechanism 20 is rotatably connected to the box body 10, and the screw 23 has a first end away from the discharge port 12. By designing the dimensional boundary conditions of the discharge section, it is convenient to convey sauces with higher viscosity (above 1000cp). The above-mentioned feeding device realizes the effective transportation and discharge of sauces by designing the specific diameter and pitch of the spiral conveying mechanism 20. The problem of blockage and leakage of the discharge port 12 is avoided.

[0049] Furthermore, along the axial direction of the screw conveying mechanism 20, at least part of the screw conveying mechanism 20 has the same pitch. This arrangement helps ensure uniform conveying of materials, avoids problems of blockage and uneven flow, and improves the efficiency and performance of the feeding device.

[0050] In an exemplary embodiment of the present application, the spiral conveying mechanism 20 has a first end close to the discharge port 12, and the spiral conveying mechanism 20 has a second end away from the discharge port 12. Along the direction from the second end to the first end, the outer diameter of at least part of the spiral conveying mechanism 20 is gradually reduced.

[0051] Specifically, the screw conveyor mechanism 20 has a first end proximal to the discharge port 12 and a second end distal to the discharge port 12. The outer diameter of at least a portion of the screw conveyor mechanism 20 gradually decreases as it moves from the second end toward the first end. This design of varying outer diameters allows the screw conveyor mechanism 20 to gradually increase the density and compressibility of the material during conveyance. This gradually decreasing outer diameter helps reduce clogging and accumulation of material during conveyance. By adopting this design, the screw conveyor mechanism 20 can more evenly convey the material to the discharge port, ensuring smooth discharge of the material.

[0052] Furthermore, the spiral conveying mechanism 20 includes a first conveying section 21 and a second conveying section 22. The first conveying section 21 is located on the side of the accommodating chamber 11 away from the discharge port 12. The first conveying section 21 is rotatably connected to the box body 10. One end of the second conveying section 22 is connected to the first conveying section 21, and the other end of the second conveying section 22 is connected to the discharge section 100. The outer diameter of the first conveying section 21 remains unchanged along the direction from the second end to the first end, and the outer diameter of the second conveying section 22 is gradually reduced along the direction from the second end to the first end.

[0053] Specifically, the first conveying section 21 is located on the side away from the discharge port 12 and is connected to the box body 10, conveying the material from the far end to the near end. The second conveying section 22 is connected to the first conveying section 21 and the discharge section 100, and is responsible for smoothly conveying the material to the discharge port 12. The gradually decreasing outer diameter of the second conveying section 22 helps increase the density and compressibility of the material, improving the fluidity and stability of the material during the conveying process.

[0054] Furthermore, the height of the bottom plane of the box body 10 at the corresponding positions of the first conveying section 21 is gradually increased from the second end to the first end. As the bottom plane height gradually increases, the space between the box body 10 and the first conveying section 21 gradually increases, facilitating the flow and conveyance of materials. Increasing the bottom plane height helps adjust the flow angle and path of materials during conveyance, ensuring smooth material delivery from the far end to the near end.

[0055] Specifically, the protrusion of the discharge port 12 is provided on the side wall of the box body 10, allowing the material to be discharged smoothly from the interior of the box body 10. The discharge channel formed within the discharge port 12 helps guide the flow of the material, preventing blockage or confusion during the discharge process. The spiral conveying mechanism 20 extends into the discharge channel, ensuring that the material is smoothly conveyed to the discharge port 12, improving the efficiency and stability of the discharge.

[0056] Furthermore, the screw conveying mechanism 20 includes a screw 23 rotatably connected to the box body. The screw conveying mechanism 20 also includes blades 24 , which are spirally arranged on the outer peripheral surface of the screw 23 along the axial direction of the screw 23 .

[0057] Specifically, blades 24 are arranged helically along the axial direction of screw 23, forming a key component of screw conveyor mechanism 20, effectively pushing and conveying materials. The number of turns A of blades 24 represents the number of turns the blades are arranged helically around the outer circumference of screw 23. This determines the propulsion force and conveying efficiency of blades 24 on the material. Through the design of blades 24, screw conveyor mechanism 20 can smoothly convey materials along the axial direction of screw 23 to discharge port 12, ensuring smooth transportation of materials.

[0058] like Figure 8 and Figure 9 As shown, there is a first gap L between the maximum outer diameter of the blade 24 on the discharge section 100 and the side wall of the discharge channel, L≤0.2mm. This arrangement is just conducive to the passage of sauces, while having a blocking effect on dry materials with different particle diameters.

[0059] Furthermore, the screw 23 is a hollow rod-shaped structure with a through hole inside. A plurality of ribs 231 are circumferentially spaced apart on the inner wall of the screw 23 , and the extending direction of the ribs 231 is parallel to the axial direction of the screw 23 .

[0060] Specifically, screw 23 is a hollow rod with a through-hole design, enabling efficient material conveying. Ribs 231 are spaced along the inner sidewall of screw 23, increasing its strength and rigidity and preventing deformation or deflection during operation. Ribs 231 extend parallel to the axis of screw 23, reducing friction and improving smoothness and conveying efficiency between screw 23 and the material.

[0061] Furthermore, the sauce feeding device also includes an end cover 30. A mounting hole is provided on the other side wall of the box body 10 opposite to the side wall where the discharge port 12 is located. Part of the end cover 30 is located in the mounting hole, and the end cover 30 is detachably connected to the box body 10.

[0062] Specifically, the feeding device further includes an end cap 30. A mounting hole is provided on the other side wall of the box body 10. Part of the end cap 30 is located in the mounting hole, and the end cap 30 is detachably connected to the box body 10. This design allows the end cap 30 to be conveniently installed on the other side wall of the box body 10 and can be easily removed for easy maintenance and cleaning.

[0063] Furthermore, a sealing groove is provided on the outer circumference of the portion of the end cap 30 located within the mounting hole. A sealed space is formed between the mounting hole wall and the sealing groove, and a sealing member is installed within the sealed space. This design ensures a good seal between the end cap 30 and the mounting hole, ensuring the stability and reliability of the feeding device. The provision of the sealing groove and sealing member improves the sealing performance of the device, effectively preventing material leakage and the ingress of foreign matter, and protecting the cleanliness and safety of the device interior.

[0064] Furthermore, the screw 23 is passed through the mounting hole and is located inside the end cover 30 . The sauce feeding device further includes an oil seal 40 . Along the radial direction of the screw 23 , the oil seal 40 is located between the screw 23 and the end cover 30 .

[0065] Specifically, screw 23 passes through the mounting hole and is located inside end cap 30, ensuring a seal between screw 23 and end cap 30. Oil seal 40 is positioned radially between screw 23 and end cap 30 to prevent leakage of lubricating oil or grease and prevent impurities from entering the space between screw 23 and end cap 30. Oil seal 40 positions the screw and provides a rotary seal to prevent material leakage, ensuring sealing and lubrication within the device.

[0066] Furthermore, a connecting portion is provided inside the end cover 30 , in which a magnetic body 50 is installed. The magnetic body 50 is in an adsorbed state with another magnetic structure on the installation base, so that the feeding device is connected to the installation base.

[0067] Specifically, a connection portion is provided within the end cap 30, within which a magnetic body 50 is mounted. The magnetic body 50 can be attracted to another magnetic structure on the mounting base, forming an adsorption state. When the feeding device needs to be connected to the mounting base, the magnetic body 50 on the end cap 30 adsorbs onto the magnetic structure on the mounting base, thereby connecting the feeding device to the mounting base.

[0068] Furthermore, the feeding device for sauce further comprises: a driving part, which is connected to the spiral conveying mechanism 20, and the driving part has a starting state to drive the spiral conveying mechanism 20 to rotate along its own axis.

[0069] Specifically, when the drive unit is activated, the motor provides power, causing the screw conveyor mechanism 20 to begin rotating. Through the drive unit, the screw conveyor mechanism 20 can smoothly convey the sauce from the container to meet production or processing needs. The connection between the drive unit and the screw conveyor mechanism 20 enables an automated sauce delivery process, improving production efficiency and reducing manual operations.

[0070] Furthermore, the feeding device for the sauce also includes a discharge nozzle assembly 60, which is detachably connected to the discharge port 12, and the discharge nozzle assembly 60 is used to guide the material discharged through the discharge port 12 to a target position.

[0071] Specifically, when the sauce is discharged through the discharge port 12, the discharge nozzle assembly 60 guides it to the target location. The detachable connection allows the discharge nozzle assembly 60 to be easily installed and removed, making it easy to clean and maintain. In addition, if the position or angle of the discharge nozzle needs to be replaced or adjusted, it can also be easily achieved.

[0072] Furthermore, the discharge nozzle assembly 60 is a silicone nozzle structure, and the discharge nozzle assembly 60 has an initial state that separates the discharge port 12 from the external environment, and the discharge nozzle assembly 60 has an open state that is at least partially opened when subjected to a force exceeding a preset force, so that the discharge port 12 is connected to the external environment.

[0073] Specifically, the discharge nozzle assembly 60 is a silicone nozzle structure. The discharge nozzle assembly 60 has an initial state and an open state. In the initial state, the discharge nozzle assembly 60 separates the discharge port 12 from the external environment. In this state, the sauce or other materials cannot flow out of the discharge port 12, which can effectively prevent impurities from entering or materials from leaking. When the discharge nozzle assembly 60 is subjected to a force exceeding a preset force, it will be converted to an open state. In this state, the discharge nozzle assembly 60 is at least partially open, so that the discharge port 12 is connected to the external environment. The sauce flows out of the discharge port 12 smoothly and is guided to the target position. This design ensures that the discharge port 12 can operate smoothly when the material needs to be discharged.

[0074] Furthermore, the feeding device for sauce also includes a switching mechanism 70, which is detachably connected to the discharge port 12. When the switching mechanism 70 is connected to the discharge port 12, one end of the switching mechanism 70 is connected to the discharge port 12, and the other end of the switching mechanism 70 is connected to the discharge nozzle assembly 60.

[0075] Specifically, the connection between the discharge port 12 and the discharge nozzle assembly 60 is established, ensuring that the sauce can flow smoothly from the discharge port 12 to the discharge nozzle assembly 60. By being detachably connected to the discharge port 12, the adapter mechanism 70 facilitates cleaning and maintenance and can be replaced or adjusted as needed. When the adapter mechanism 70 is connected to the discharge port 12, the sauce flows from the discharge port 12 through one end of the adapter mechanism 70 and then transfers to the other end to connect to the discharge nozzle assembly 60. In this way, the adapter mechanism 70 acts as a bridge, achieving a smooth connection and transfer between the discharge port 12 and the discharge nozzle assembly 60.

[0076] Furthermore, a sealing gasket is provided at the connection between the adapter mechanism 70 and the discharge port 12. The function of the sealing gasket is to ensure the sealing of the connection and prevent the sauce or other materials from leaking from the connection or the outside air from entering.

[0077] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0078] 1. The sauce feeding device includes a box body and a screw conveyor mechanism. The box body has a storage chamber and a discharge port. The screw conveyor mechanism is disposed within the storage chamber, forming a material space between the screw conveyor mechanism and the sidewalls of the storage chamber.

The screw conveyor mechanism rotates about its central axis to transport the material in the material space along the axial direction of the screw conveyor mechanism to the discharge port. The screw in the screw conveyor mechanism is rotatably connected to the box body and has a first end remote from the discharge port.

[0079] 2. Parameter B is greater than or equal to 40. By designing the screw conveyor mechanism with specific boundary dimensions, the sauce can be effectively conveyed and discharged, avoiding problems such as blockage and leakage at the discharge port.
