A mobile feeding device for food packaging

Abstract

This invention relates to the field of food processing equipment technology, specifically a mobile feeding device for food packaging. It includes a vertical screw conveyor, a support frame mounted on one side of the vertical screw conveyor, and a mobile hopper mounted on the top side of the support frame. Several packaging machines are mounted on one side of the support frame. In industrial food processing, the workshop conveying feeding device, through the adjustable feeding components, enables the inclined tube to rotate and change angle simultaneously, forming a spiral feeding trajectory. The rotational motion ensures that the material is covered circumferentially without dead angles along the wall of the packaging machine's storage tank, completely solving the problem of dense feeding at the center and sparse feeding at the edges in traditional methods. The dynamic change in inclination angle allows the material drop point to naturally disperse in the vertical direction, ensuring uniform material reception in different height areas within the tank and effectively controlling differences in bulk density. This uniform spatial distribution directly improves the metering stability of subsequent packaging processes, ensuring consistent packaging weight in industrial production.

Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically a mobile feeding device for food packaging. Background Technology

[0002] In the industrialized food processing system, food packaging is a key link connecting production and distribution, directly affecting the product's shelf life, transportation safety, and market performance. With the continuous expansion of the scale and diversification of food industrialization, the packaging process places higher demands on the accuracy, continuity, and automation of material transportation. It needs to achieve stable transfer of materials in different forms while avoiding material contamination and ensuring metering accuracy. Therefore, mobile feeding devices have become one of the core auxiliary equipment in this process.

[0003] Existing mobile feeding devices generally use a straight cylindrical discharge pipe, combined with a discharge port fixed in a single position. This design ensures that the material maintains a vertical downward trajectory during its descent, ultimately concentrating on impacting the central area inside the storage tank at the top of the packaging machine. After impacting the bottom of the tank, the material naturally spreads outwards. However, due to friction between material particles and between the material and the tank wall, the diffusion range is limited, forming a cone shape that extends gently towards the tank wall from the discharge point. This cone-shaped accumulation occupies the lower space inside the tank, while a large amount of space at the top remains unused because the material cannot fill it naturally. This results in the actual usable space of the storage tank being far less than its designed volume, failing to fully utilize its storage capacity. Therefore, frequent replenishment is required to maintain production, indirectly increasing the feeding frequency. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile feeding device for food packaging, which solves the problem mentioned in the background art that existing mobile feeding devices generally use a straight cylindrical discharge pipe with a discharge port fixed at a single position. This design causes the material to maintain a vertical downward trajectory during the falling process, forming a cone shape that extends gently towards the can wall with the discharge point as the apex. This cone-shaped accumulation occupies the lower space inside the can, while a large amount of space inside the can remains idle because the material cannot fill it naturally. As a result, the actual usable space of the storage tank is much smaller 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.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile feeding device for food packaging, comprising a vertical screw conveyor, a support frame disposed on one side of the vertical screw conveyor, and a mobile hopper disposed on one side of the top of the support frame. Several packaging machines are disposed on one side of the support frame. A vertical discharge pipe is fixedly installed at the bottom of the mobile hopper. A spring tension tube is disposed at the bottom of the vertical discharge pipe. An inclined tube is fixedly installed at the output end of the spring tension tube. A discharge head is fixedly installed at the output end of the inclined tube. A connecting ring is fixedly installed near the top of the spring tension tube close to the top of the vertical discharge pipe. The top of the connecting ring is rotatably engaged with the bottom of the vertical discharge pipe. An adjustable feeding assembly and an anti-residue assembly are disposed outside the connecting ring. The adjustable feeding assembly includes a first positioning frame, a positioning ring, and a fixing ring. The first positioning frame is fixedly installed outside one side of the connecting ring. The positioning ring is fixedly installed outside one side of the inclined tube. The fixing ring is fixedly installed outside one side of the bottom of the vertical discharge pipe.

[0006] Furthermore, a guide frame is horizontally fixedly installed at the top of the support frame, a rotating shaft is longitudinally installed through the middle of the interior of the movable hopper, a solenoid valve is fixedly installed inside the output end of the discharge head, a control motor is fixedly installed at the middle of the top of the movable hopper via a bracket, the output end of the control motor is coaxially fixed with the top of the rotating shaft, a fixing rod is vertically and horizontally fixedly installed at the bottom of the rotating shaft, and the two ends of the fixing rod are fixedly installed on the inner wall of one side of the connecting ring.

[0007] Furthermore, a limiting groove is formed through the interior of the guide frame, and a fixed frame is fixedly installed on the outside of one side of the movable hopper. A positioning slider is fixedly installed through the middle of the interior of the fixed frame. The positioning slider is slidably engaged inside one side of the limiting groove. A reciprocating screw is threadedly connected inside the positioning slider. The two ends of the reciprocating screw are rotatably installed on the inner walls of both sides of the limiting groove. A drive motor is fixedly installed on the outside of one side of the guide frame, and the output end of the drive motor is coaxially fixed with one end of the reciprocating screw.

[0008] Furthermore, a positioning shaft is rotatably mounted on one side of the bottom end of the first positioning frame, and a second positioning frame is fixedly mounted on the side of the positioning ring near the first positioning frame. The second positioning frame is fixedly mounted through and on one side of the positioning shaft. A worm gear is fixedly mounted on one end of the positioning shaft. An auxiliary frame is fixedly mounted on one side of the first positioning frame. A worm is rotatably mounted longitudinally through the interior of the auxiliary frame, and one side of the worm is meshed with one side of the worm gear.

[0009] Furthermore, a rotating rod is coaxially fixedly installed at the top end of the worm gear, a gear is fixedly installed at the top end of the rotating rod, and several teeth are fixedly installed on the outer edge of the fixed ring near the gear.

[0010] Furthermore, an arc-shaped frame is fixedly installed on one side of the first positioning frame, and forward and reverse compression buttons are fixedly installed on both ends of the arc-shaped frame. Compression blocks are fixedly installed on the side of the second positioning frame near the forward and reverse compression buttons.

[0011] Furthermore, the anti-residue component includes two support brackets and several guide slots. The two support brackets are symmetrically and laterally fixedly installed on the outside of one side of the connecting ring, and the several guide slots are all embedded inside one side edge of the fixed ring.

[0012] Furthermore, each of the support brackets has an auxiliary sliding groove through which an auxiliary slider is slidably engaged. An abutment roller is rotatably mounted on one side of the top of the auxiliary slider, and one side of the abutment roller abuts against the outer edge of one side of the fixing ring.

[0013] Furthermore, a guide rod is slidably installed inside the auxiliary slider. The two ends of the guide rod are fixedly installed on the inner wall of one side of the auxiliary slide groove.

[0014] Furthermore, a mounting bracket is fixedly installed at the bottom of the auxiliary slider, and several mounting rods are fixedly installed at equal intervals on the outer side of the mounting bracket near the spring tension tube. A striking ball is fixedly installed at one end of each of the mounting rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In industrial food processing, the feeding device for workshop conveyors, through the setting of adjustable feeding components, enables the inclined tube to rotate and change angle simultaneously, forming a spiral feeding trajectory. The rotational motion ensures that the material is covered around the circumference of the packaging machine's storage tank without any dead angles, completely solving the problem of dense feeding at the center and sparse feeding at the edges in traditional feeding methods. The dynamic change of the inclination angle allows the material drop point to be naturally dispersed in the vertical direction, ensuring uniform material reception in different height areas within the tank and effectively controlling differences in bulk density. This uniform spatial distribution directly improves the metering stability of subsequent packaging processes, providing a reliable guarantee for the consistency of packaging weight in industrial production. The overall feeding efficiency and uniformity are significantly improved, making it more suitable for the continuous production needs of industrial food processing.

[0017] 2. When the adjustable feeding component is running, the anti-residue component is triggered synchronously. By intermittently striking the spring tension tube, vibration is generated on both sides of the spring tension tube. The vibration is converted into high-frequency micro-vibrations on the tube wall, causing the material adhering to the inner wall of the spring tension tube to detach from the tube wall due to vibration and be discharged with the mainstream material. This reduces residue from the source and ensures that the inner wall of the spring tension tube is clean. For industrial food processing, this design can reduce material waste, reduce the risk of residual material oxidation and deterioration or microbial growth, reduce the frequency of manual cleaning in the later stage, and improve the overall use effect.

[0031] Example 1: Please refer to Figure 1 - Figure 8 A mobile feeding device for food packaging includes a vertical screw conveyor 1, a support frame 2 disposed on one side of the vertical screw conveyor 1, and a mobile hopper 4 disposed on one side of the top of the support frame 2. Several packaging machines 5 are disposed on one side of the support frame 2. A vertical discharge pipe 11 is fixedly installed at the bottom of the mobile hopper 4. A spring tension pipe 12 is disposed at the bottom of the vertical discharge pipe 11. An inclined pipe 13 is fixedly installed at the output end of the spring tension pipe 12.

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

[0032] A guide frame 3 is horizontally fixedly installed at the top of the support frame 2. A rotating shaft 16 is longitudinally installed through the middle of the interior of the movable hopper 4. A solenoid valve 17 is fixedly installed inside the output end of the discharge head 14. A control motor 15 is fixedly installed at the middle of the top of the movable hopper 4 through a bracket. The output end of the control motor 15 is coaxially fixed with the top of the rotating shaft 16. A fixing rod 18 is vertically and horizontally fixedly installed at the bottom 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.

[0033] A limiting groove 7 is opened through the inside of the guide frame 3. A fixed frame 6 is fixedly installed on the outside of one side of the movable hopper 4. A positioning slider 8 is fixedly installed through the middle of the inside of the fixed frame 6. The positioning slider 8 is slidably engaged and installed inside one side of the limiting groove 7. A reciprocating screw 9 is threadedly connected inside the positioning slider 8. The two ends of the reciprocating screw 9 are rotatably installed through the inner walls of the two sides of the limiting groove 7. A drive motor 10 is fixedly installed on the outside of one side of the guide frame 3. The output end of the drive motor 10 is coaxially fixed with one end of the reciprocating screw 9.

[0034] A positioning shaft 21 is rotatably mounted on one side of the bottom of the first positioning frame 20. A second positioning frame 23 is fixedly mounted on the side of the positioning ring 22 near the first positioning frame 20. The second positioning frame 23 is fixedly mounted on 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 one side of the first positioning frame 20. A worm 26 is rotatably mounted longitudinally inside the auxiliary frame 25. One side of the worm 26 is meshed with one side of the worm gear 24.

[0035] A rotating rod 31 is coaxially fixedly installed at the top of the worm gear 26, and a gear 32 is fixedly installed at the top of the rotating rod 31. Several teeth 33 are fixedly installed on the outer edge of the fixed ring 30 near the gear 32.

[0036] An arc-shaped frame 27 is fixedly installed on one side of the first positioning frame 20. A forward and reverse squeeze button 28 is fixedly installed on both ends of the arc-shaped frame 27. A squeeze block 29 is fixedly installed on the side of the second positioning frame 23 near the forward and reverse squeeze button 28.

[0037] Specifically, the curvature of the arc frame 27 is perfectly matched with the rotation trajectory of the extrusion block 29 driven by the second positioning frame 23. As the second positioning frame 23 rotates around the positioning axis 21, the movement path of the extrusion block 29 is arc-shaped, and the curvature of the arc frame 27 matches it. This ensures that the extrusion block 29 always moves smoothly along the inner side of the arc frame 27 during rotation, avoiding accidental touch or touch failure caused by trajectory misalignment, and ensuring the accuracy of button triggering.

[0038] In this embodiment, when the mobile feeding device for industrial food processing is working, the material is first stably conveyed to the mobile hopper 4 by the vertical screw conveyor 1 for temporary storage. At this time, the drive motor 10 starts 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 groove 7, the rotation of the reciprocating screw 9 drives the positioning slider 8 to move laterally inside the guide frame 3. Then, through the fixed frame 6, the mobile hopper 4 is driven to move smoothly along the guide frame 3, realizing precise alignment and feeding with multiple packaging machines 5, avoiding the error of manual adjustment of alignment, and improving the efficiency of multi-station switching.

[0039] It should also be noted that the material in the mobile hopper 4, under the action of gravity, enters the spring tension tube 12 through the vertical discharge pipe 11. Finally, the material is discharged from the discharge head 14 by controlling the solenoid valve 17 to achieve feeding. At the same time, the motor 15 drives 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 tension tube 12 and the inclined tube 13 to revolve, ensuring that the discharge head 14 can transport materials around the circumference of the storage tank of the packaging machine 5. During the revolution, the gear 32 on the outside of the connecting ring 19 intermittently meshes with the teeth 33 on the edge of the fixed ring 30, causing the gear 32 to rotate and drive the rotating rod 31 and the worm 26 to rotate synchronously. The meshing transmission between 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 the dynamic adjustment of the tilt angle of the inclined tube 13 (e.g., Figure 8 As shown, when the extrusion block 29 on the second positioning frame 23 rotates and touches the forward and reverse extrusion buttons 28 at both ends of the arc frame 27, it can automatically switch the rotation direction of the output shaft of the control motor 15, thereby realizing the automatic switching of the tilt angle adjustment direction of the tilt tube 13. This ensures that the tilt angle changes repeatedly within a reasonable range, allowing the discharge head 14 to form a spiral feeding trajectory when feeding. The revolution motion ensures that the material is covered without dead corners along the circumference of the storage tank wall, completely solving the problem of dense center and sparse edge feeding in traditional feeding. The dynamic change of the tilt angle allows the material drop point to be naturally dispersed in the vertical direction, so that the material is evenly received in different height areas inside the tank, effectively controlling the difference in bulk density. 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 industrial production, and the overall feeding effect is better.

[0040] Example 2: Please refer to Figure 9 - Figure 11 This embodiment further illustrates the first embodiment. The anti-residue component includes two support brackets 34 and several guide grooves 40. The two support brackets 34 are symmetrically and horizontally fixedly installed on the outside of one side of the connecting ring 19, and the several guide grooves 40 are all embedded in the inside of one side edge of the fixing ring 30.

[0041] Each support bracket 34 has an auxiliary slide groove 35 through which an auxiliary slider 36 is slidably engaged inside the auxiliary slide groove 35. An abutment roller 39 is rotatably mounted on one side of the top of the auxiliary slider 36. One side of the abutment roller 39 abuts against the outer edge of one side of the fixing ring 30.

[0042] A guide rod 37 is slidably installed inside the auxiliary slider 36. The two ends of the guide rod 37 are fixedly installed on the inner wall of one side of the auxiliary slide groove 35. A compression spring 38 is sleeved through the outer side of one side of the guide rod 37. The two ends of the compression spring 38 are respectively fixedly installed on the outer side of one side of the auxiliary slider 36 and the inner wall of the auxiliary slide groove 35.

[0043] 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. It can precisely 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 misalignment of the striking position due to lateral offset. This rigid guiding effect can prevent the auxiliary slider 36 from getting stuck in the movement, ensure the continuity of the intermittent striking action, and ensure the overall operation stability.

[0044] A mounting bracket 41 is fixedly installed at the bottom of the auxiliary slider 36. Several mounting rods 42 are fixedly installed at equal intervals on the outer side of the mounting bracket 41 near the spring tension tube 12. A striking ball 43 is fixedly installed at one end of each mounting rod 42.

[0045] 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 causes the spring tension tube 12 and the two side support brackets 34 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 at the edge of the fixed ring 30 with the revolution, the concave structure of the guide groove 40 will force the abutting roller 39 to drive the auxiliary slider 36 to slide along the auxiliary slide groove 35 of the support bracket 34 towards the spring tension tube 12. At the same time, the compression spring 38 sleeved on the guide rod 37 will rebound and generate a squeezing force. The striking ball 43 on the mounting bracket 41 at the bottom 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 impact ball 43 moves away from the two sides of the spring-tension tube 12. This linkage mechanism allows the impact ball 43 to intermittently strike the tube as the connecting ring 19 revolves. Each revolution of the connecting ring 19 causes the impact ball 39 to pass through several guide grooves 40, corresponding to several impact actions. The vibration generated by the impact is transmitted to the inner wall through the tube wall of the spring-tension tube 12, causing the adhered material to detach from the tube wall due to vibration (especially suitable for sticky or powdery materials). The material detached from the tube wall is discharged with the mainstream material through the inclined tube 13 and the discharge head 14, thus completing the anti-residue cleaning simultaneously during the feeding process, avoiding the material from accumulating in the spring-tension tube 12, and improving the overall performance.
