Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, in particular to a mobile feeding device for food packaging. Background Art

[0002] In the food industrial processing system, food packaging is a key link connecting production and circulation, directly affecting the product's shelf life, transportation safety and market presentation. With the continuous expansion of the scale of food industrial processing and the continuous enrichment of product categories, the packaging link has put forward higher requirements on the accuracy, continuity and degree of automation of material transportation. It is necessary to achieve stable transportation of materials of different forms, avoid material contamination and ensure metering accuracy. Therefore, mobile feeding devices have become one of the core auxiliary equipment in this link.

[0003] Existing mobile feeding devices generally use a straight-cylinder drop tube with a drop port fixed at a single position. This design allows the material to always maintain a vertical downward motion trajectory during the falling process, and finally concentrate on impacting the central area inside the storage tank at the top of the packaging machine. After hitting the bottom of the tank, the material will naturally diffuse to the surroundings, but due to the friction between the material particles and between the material and the tank wall, the diffusion range is limited, forming a cone shape with the drop point as the vertex and extending smoothly toward the tank wall. This conical accumulation will occupy the space below the tank, while a large amount of space above the tank is idle because the material cannot be naturally filled. As a result, the actual use space of the storage tank is far less than its designed volume, and the storage capacity cannot be fully utilized. Therefore, frequent replenishment is required to maintain production, which indirectly increases the feeding frequency. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In industrialized food processing, the workshop conveying feeding device uses an adjustable feeding component to enable the inclined tube to rotate while changing angle, forming a spiral feeding trajectory. The revolution ensures that the material is covered along the circumference of the packaging machine storage tank without blind spots, completely solving the problem of dense center and sparse edges in traditional feeding. The dynamic change of the inclination angle allows the material drop points to be naturally dispersed in the vertical direction, so that different height areas in the tank are evenly connected and the difference in bulk density is effectively controlled. This uniform spatial distribution directly improves the metering stability of the subsequent packaging process, providing a reliable guarantee for the consistency of packaging weight in industrialized production. The overall feeding efficiency and uniformity are significantly improved, making it more suitable for the continuous production needs of industrialized food. 2. When the adjustable feeding component is running, the anti-residue component is triggered to run synchronously with it. By intermittently knocking on the spring stretch tube, the two sides of the spring stretch tube are vibrated. The vibration will be converted into high-frequency micro-tremors of the tube wall, so that the material adhering to the inner wall of the spring stretch tube is separated from the tube wall due to vibration and discharged with the mainstream material, reducing residue from the source and ensuring the overall cleanliness of the inner wall of the spring stretch tube. For industrial food processing, this design can reduce material waste, while reducing the risk of residual material oxidation and deterioration or breeding of microorganisms, reducing the frequency of later manual cleaning, and improving the overall use effect.

The top of the connecting ring 19 is rotatably engaged with the bottom of the vertical discharge pipe 11. An adjustable feeding assembly and an anti-residue assembly are provided on the outside of the connecting ring 19. The adjustable feeding assembly includes a first positioning frame 20, a positioning ring 22, and a fixing ring 30. The first positioning frame 20 is fixedly installed on the outside of one side of the connecting ring 19. The positioning ring 22 is fixedly installed on the outside of one side of the inclined pipe 13. The fixing ring 30 is fixedly installed on the outside of one side of the bottom end of the vertical discharge pipe 11.

[0020] The guide frame 3 is fixedly installed horizontally on the top of the support frame 2, a rotating shaft 16 is longitudinally penetrated by the middle position of the inside of the mobile hopper 4, a solenoid valve 17 is fixedly installed inside the output end of the discharge head 14, and a control motor 15 is fixedly installed on the middle position of the top of the mobile hopper 4 through a bracket. The output end of the control motor 15 is coaxially fixed with the top of the rotating shaft 16, and a fixing rod 18 is fixedly installed vertically and horizontally on the bottom end of the rotating shaft 16. The two ends of the fixing rod 18 are fixedly installed on the inner wall of one side of the connecting ring 19.

[0021] A limiting chute 7 is provided through the interior of the guide frame 3, and a fixed frame 6 is fixedly installed on the outside of one side of the mobile hopper 4. A positioning slider 8 is fixedly provided through the middle position of the interior of the fixed frame 6. The positioning slider 8 is slidably engaged and installed inside one side of the limiting chute 7. A reciprocating screw 9 is threadedly provided inside the positioning slider 8. The two ends of the reciprocating screw 9 are rotatably installed on the inner walls of both sides of the limiting chute 7. A drive motor 10 is fixedly installed on the outside of one side of the guide frame 3, and the output end of the drive motor 10 is coaxially fixed with one end of the reciprocating screw 9.

[0022] A positioning shaft 21 is rotatably mounted on the outside of one side of the bottom end of the first positioning frame 20, a second positioning frame 23 is fixedly mounted on the outside of one side of the positioning ring 22 close to the first positioning frame 20, the second positioning frame 23 is fixedly mounted on the outside of one side of the positioning shaft 21, a worm gear 24 is fixedly mounted on one end of the positioning shaft 21, an auxiliary frame 25 is fixedly mounted on the outside of one side of the first positioning frame 20, a worm 26 is rotatably mounted on the inside of the auxiliary frame 25 longitudinally, and one side of the worm gear 26 is meshed with one side of the worm gear 24.

[0023] A rotating rod 31 is coaxially fixedly mounted on the top of the worm 26 , a gear 32 is fixedly mounted on the top of the rotating rod 31 , and a plurality of teeth 33 are fixedly mounted on the outer edge of one side of the fixing ring 30 close to the gear 32 .

[0024] An arc frame 27 is fixedly installed on the outside of one side of the first positioning frame 20, and forward and reverse extrusion buttons 28 are fixedly installed on both ends of the arc frame 27. An extrusion block 29 is fixedly installed on the outside of one side of the second positioning frame 23 near the forward and reverse extrusion buttons 28.

[0025] Specifically, the curvature of the arc frame 27 is fully compatible with the rotation trajectory of the extrusion block 29 driven by the second positioning frame 23. Because when the second positioning frame 23 rotates around the positioning axis 21, the movement path of the extrusion block 29 is an arc, and the curvature of the arc frame 27 matches it, which can ensure that the extrusion block 29 always moves smoothly along the inner side of the arc frame 27 during the rotation process, avoiding accidental touch or touch failure caused by trajectory misalignment, and ensuring the accuracy of button triggering.

[0026] In this embodiment, when the mobile feeding device for industrial food processing is working, the material is first stably transported to the mobile hopper 4 for temporary storage through the vertical screw conveyor 1. At this time, the drive motor 10 is started and drives the reciprocating screw 9 to rotate. Due to the threaded connection between the positioning slider 8 and the reciprocating screw 9 and the sliding engagement connection between the positioning slider 8 and the limiting slide 7, the reciprocating screw 9 rotates and drives the positioning slider 8 to move horizontally inside the guide frame 3, and then drives the mobile hopper 4 to move smoothly along the guide frame 3 through the fixed frame 6, thereby realizing precise positioning feeding with multiple packaging machines 5, avoiding errors in manual positioning adjustment, and improving the efficiency of multi-station switching.

[0027] It should also be noted that, under the action of gravity, the material in the mobile hopper 4 enters the spring stretching tube 12 through the vertical discharge pipe 11, and finally the electromagnetic valve 17 is controlled to be opened, so that the material is discharged from the discharge head 14 to realize feeding. At the same time, the motor 15 is controlled to drive the rotating shaft 16 to rotate. The rotating shaft 16 drives the connecting ring 19 to rotate around the bottom end of the vertical discharge pipe 11 through the bottom fixed rod 18. The connecting ring 19 synchronously drives the spring stretching tube 12 and the inclined tube 13 to perform orbital motion to ensure that the discharge head 14 can convey the material along the circumference of the storage tank of the packaging machine 5. During the orbital motion, the gear 32 on the outside of the connecting ring 19 is intermittently meshed with the teeth 33 on the edge of the fixed ring 30, so that the gear 32 rotates and drives the rotating rod 31 and the worm 26 to rotate synchronously. The meshing transmission of the worm 26 and the worm wheel 24 causes the positioning shaft 21 to rotate. The positioning shaft 21 drives the inclined tube 13 to rotate around the positioning ring 22 through the second positioning frame 23, thereby realizing dynamic adjustment of the inclination angle of the inclined tube 13 (such as Figure 8 As shown in the figure, when the extrusion block 29 on the second positioning frame 23 rotates and touches the forward and reverse extrusion buttons 28 at each end of the arc frame 27, it can automatically switch the rotation direction of the output shaft of the control motor 15, thereby automatically switching the tilt angle adjustment direction of the tilt tube 13, ensuring that the tilt angle changes back and forth within a reasonable range, so that the discharge head 14 can form a spiral feeding trajectory during feeding. The revolution ensures that the material is covered along the circumference of the storage tank wall without dead angles, completely solving the problem of traditional feeding with dense center and sparse edges. The dynamic change of the tilt angle allows the material drop points to be naturally dispersed in the vertical direction, so that different height areas in the tank are evenly connected to the material, effectively controlling the difference in bulk density. This uniform spatial distribution directly improves the metering stability of the subsequent packaging process, provides reliable guarantee for the consistency of packaging weight in industrial production, and improves the overall feeding effect.

[0028] Example 2: Please refer to Figure 9 - Figure 11 This embodiment further explains Example 1. The anti-residue component includes two support brackets 34 and a plurality of guide grooves 40. The two support brackets 34 are symmetrically and laterally fixedly installed on the outside of one side of the connecting ring 19, and the plurality of guide grooves 40 are embedded inside the edge of one side of the fixing ring 30.

[0029] An auxiliary slide groove 35 is provided inside each support bracket 34, and an auxiliary slider 36 is installed in the auxiliary slide groove 35 for sliding engagement. A contact roller 39 is rotatably installed on one side of the top of the auxiliary slider 36, and one side of the contact roller 39 contacts and fits with the outside of one edge of the fixing ring 30.

[0030] A guide rod 37 is slidably installed inside the auxiliary slider 36, and both ends of the guide rod 37 are fixedly installed on the inner wall of one side of the auxiliary slide 35. A compression spring 38 is sleeved through the outside of one side of the guide rod 37, and both ends of the compression spring 38 are respectively fixedly installed on the outside of one side of the auxiliary slider 36 and one side of the inner wall of the auxiliary slide 35.

[0031] Specifically, the guide rod 37 passes through the auxiliary slider 36 and is fixed at both ends to the inner wall of the auxiliary slide groove 35, which can accurately limit the movement trajectory of the auxiliary slider 36 so that it can only slide in a straight line along the direction of the guide rod 37, avoiding the misalignment of the knocking position due to lateral offset. This rigid guiding effect can prevent the auxiliary slider 36 from getting stuck during movement, ensure the continuity of the intermittent knocking action, and ensure the overall operation stability.

[0032] A mounting frame 41 is fixedly mounted on the bottom end of the auxiliary slider 36 , and a plurality of mounting rods 42 are fixedly mounted at equal intervals on the outside of the mounting frame 41 close to the spring tension tube 12 , and a knocking ball 43 is fixedly mounted on one end of each of the mounting rods 42 .

[0033] In this embodiment, when the control motor 15 drives the connecting ring 19 to revolve around the vertical discharge pipe 11, the rotation of the connecting ring 19 drives the spring tension tube 12 and the supporting brackets 34 on both sides to revolve synchronously, so that the abutting roller 39 at the top of the auxiliary slider 36 is always in contact with the edge of the fixed ring 30. When the abutting roller 39 enters the guide groove 40 on the edge of the fixed ring 30 with the revolving movement, the concave structure of the guide groove 40 forces the abutting roller 39 to drive the auxiliary slider 36 to slide along the auxiliary slide groove 35 of the supporting bracket 34 in the direction close to the spring tension tube 12. At the same time, the compression spring 38 sleeved on the guide rod 37 will rebound and generate an extrusion force. The knocking ball 43 on the mounting bracket 41 at the bottom end of the auxiliary slider 36 moves synchronously with the auxiliary slider 36, and under the inertia of the rebound of the compression spring 38, The spring stretch tube 12 is quickly impacted on both sides of the tube wall. When the friction roller 39 rotates out of the guide groove 40, the compression spring 38 is compressed, pushing the auxiliary slider 36 to reset, and the knocking ball 43 is away from the two sides of the tube wall of the spring stretch tube 12. This linkage mechanism enables the knocking ball 43 to achieve intermittent knocking with the revolution of the connecting ring 19: for each revolution, the friction roller 39 passes through several guide grooves 40, corresponding to completing several impact actions. The vibration generated by the impact is transmitted to the inner wall through the tube wall of the spring stretch tube 12, so that the adhered material is separated from the tube wall due to the vibration (especially suitable for sticky or powdery materials). The material separated from the tube wall is discharged with the mainstream material through the inclined tube 13 and the discharge head 14, thereby completing anti-residue cleaning synchronously during the feeding process, avoiding the retention and accumulation of materials in the spring stretch tube 12, and the overall use effect is better.
