Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a quantitative feeding mechanism for food processing. Background Technology

[0002] In the food processing process, the quantitative input of raw materials is one of the key links to ensure the stability of product quality. Traditional input methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to accurately control the amount of raw materials, and can easily lead to deviations in product taste and composition due to human factors.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent with announcement number CN220299787U, announcement date 2024-01-05) discloses a food additive dispensing machine, including a dispensing body; the dispensing body has a cavity and a dispensing port and a dispensing port respectively communicating with the upper and lower ends of the cavity; a material equalization device and a metering device are arranged sequentially from top to bottom in the cavity; the material equalization device includes a material equalization disc and a rotating shaft; the rotating shaft is rotatably mounted on the inner wall of the dispensing body; the material equalization disc... The central part is fitted onto the surface of the rotating shaft. Several feeding holes are distributed on the material equalization plate. A baffle is abutted against the bottom surface of the material equalization plate. The baffle is fixedly installed on the inner wall of the feeding body. A feeding port is opened on one side of the baffle. The metering device is located below the baffle and is used to catch the material falling from the feeding port. Through the design of the material equalization device, the material stored in the cavity can be kept in a dispersed state and fed into the corresponding feeding holes at a uniform speed and in a uniform amount, effectively preventing the material from clogging during feeding and improving work efficiency.

[0004] There is also prior art 2 (Chinese patent with announcement number CN112722729B and announcement date of 2022-04-22) a quantitative feeding device for food processing, including a support base, a conveying mechanism on the support base, a drive mechanism fixedly installed on the outside of the conveying mechanism, a feeding mechanism at the upper end of the conveying mechanism outside the support base, a transmission mechanism at one end of the conveying mechanism inside the support base, a switching mechanism at the position of the transmission mechanism corresponding to the feeding mechanism, and an adjustment mechanism inside the feeding mechanism. In use, the second threaded rod can be rotated by turning the handle, and the second threaded rod can drive the sealing block to rise, thereby adjusting the internal volume of the storage chamber. At this time, it can be directly adjusted according to the raw material ratio. After use, the corresponding raw material can be filled into the storage chamber to complete the raw material ratio, making the quantitative feeding of raw materials simple and convenient.

[0005] While existing technologies have addressed the feeding problem in food processing to some extent, they still have some shortcomings. Existing technology one primarily achieves uniform feeding through a uniform feeding tray and a metering device. Its anti-clogging mechanism focuses on dispersing and evenly distributing materials. However, for some highly viscous or easily agglomerated raw materials, simple uniform feeding may not completely prevent jamming or blockage at the feeding port or conveying channel. Existing technology two achieves metering by adjusting the volume of the storage chamber, which is relatively convenient to operate. However, during continuous feeding, blockages may still occur when raw materials enter the subsequent conveying stage from the storage chamber due to the characteristics of the raw materials themselves or structural problems of the conveying pipeline. Furthermore, its measures for preventing and handling blockages are relatively simple.

[0006] Therefore, we propose a quantitative feeding mechanism for food processing to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a quantitative feeding mechanism for food processing, in order to solve the problems mentioned in the background art. For some raw materials with high viscosity or easy agglomeration, simple uniform feeding may not be able to completely avoid jamming or blockage in the feeding port or conveying channel. In the continuous feeding process, when the raw material enters the subsequent conveying stage from the storage chamber, blockage may still occur due to the characteristics of the raw material itself or the structural problems of the conveying pipeline.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a quantitative feeding mechanism for food processing, comprising a frame, a feeding bin for feeding is fixedly connected to the upper part of the frame, and a feeding pipe is also fixedly connected to the frame. A fixed box is fixedly connected to the frame, and a discharge hole is provided on the fixed box. A striking mechanism is provided inside the fixed box and on its side. The striking mechanism strikes the fixed box by rotating the feeding cylinder contained therein, thereby preventing the feeding from getting stuck. An auxiliary mechanism is also provided on the frame. The auxiliary mechanism is located below the feeding pipe, and the auxiliary mechanism strikes the feeding pipe by rotating the striking roller contained therein, thereby further preventing the raw material from clogging the feeding pipe.

[0009] Preferably, the fixing box is located between the feeding bin and the feeding pipe, and the single discharge hole on the fixing box corresponds to the feeding inlet of the feeding pipe. A first motor assembly is fixedly connected to the frame, and a drive shaft is fixedly connected to the output end of the first motor assembly, and the drive shaft is disposed through the center of the fixing box.

[0010] Preferably, a rotating box is fixedly connected to the outside of the drive shaft, and the rotating box is located inside the fixed box. A feeding cylinder is arranged in a ring on the rotating box, and the discharge port diameter of the feeding cylinder is smaller than the maximum value of the discharge hole diameter of the fixed box. The lower end of the feeding cylinder is in close contact with the fixed box. A cleaning plate for cleaning scattered raw materials is fixedly connected to the lower surface of the rotating box.

[0011] Preferably, the striking mechanism includes a striking plate, which is rotatably connected to the outside of the fixed box. The upper end of the striking plate is provided with a sliding groove, and an abutment rod is slidably connected inside the sliding groove. The sliding groove is also arranged in an inclined structure.

[0012] Preferably, a connecting plate is fixedly connected to the upper end of the abutment rod, and a sliding plate is fixedly connected to the inner side of the connecting plate. The sliding plate is slidably disposed through the side of the fixed box. A spring is fixedly connected between the outer side of the fixed box and the inner side of the connecting plate, and the sliding plate can be reset by the spring.

[0013] Preferably, both sides of the inner end of the sliding plate are inclined, and an abutment plate is fixedly connected to the outer side of the rotating box. The outer end of the abutment plate is arc-shaped, and when the abutment plate rotates under the action of the rotating box, the outer end of the abutment plate presses against the sliding plate.

[0014] Preferably, the auxiliary mechanism includes a second motor assembly, which is fixedly connected to the lower part of the frame, and two sets of linkage shafts are rotatably connected to the frame, with one end of each linkage shaft fixedly connected to the second motor assembly.

[0015] Preferably, gear assemblies are fixedly connected to the outer side of each linkage shaft, and the two sets of gear assemblies mesh with each other, and a drive roller is fixedly connected to the other end of the linkage shaft.

[0016] Preferably, a driven roller is rotatably connected to the frame, and the driven roller is located above the drive roller. A belt is sleeved between the drive roller and the outer side of the driven roller. A striking roller is rotatably connected to the frame, and protrusions are evenly distributed on the outer side of the striking roller. The side of the striking roller is in contact with the belt. The striking roller rotates due to the friction of the belt, thereby striking the outer side of the feeding tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) A feeding cylinder is provided. When feeding is required, the first motor assembly drives the drive shaft to rotate. The drive shaft then drives the rotating box to rotate inside the fixed box. The feeding cylinders arranged in a ring on the rotating box rotate together with it. When the feeding cylinder rotates to the position corresponding to the discharge port of the feeding bin, the raw material in the feeding bin will fall into the feeding cylinder to complete the quantitative receiving. As the rotating box continues to rotate, when the feeding cylinder containing the raw material rotates to the position of the discharge hole opened on the fixed box, since the lower end of the feeding cylinder is in contact with the fixed box, the raw material in the feeding cylinder can accurately fall into the corresponding feeding pipe inlet below through the discharge hole, thereby realizing the quantitative and orderly feeding of the raw material.

[0018] (2) The cleaning plate fixedly connected to the lower surface of the rotating box also rotates, which can clean up the raw materials that may be scattered inside the fixed box in time, prevent the raw materials from accumulating in the fixed box, and ensure the cleanliness of the feeding environment and the smoothness of the feeding process.

[0019] (3) When the rotating box rotates, the abutment plate rotates synchronously. Its arc-shaped outer end contacts the inclined surface of the inner end of the sliding plate and generates a squeezing force, causing the sliding plate to drive the connecting plate and the abutment rod to move outward. The spring is stretched, and the abutment rod slides in the groove, causing the lower end of the striking plate to lift up. After the abutment plate passes the sliding plate, the spring resets and drives each component to reset. The lower end of the striking plate strikes the outer wall of the fixed box, and the rotating box continues to rotate, realizing the intermittent striking of the striking plate to prevent the raw material from getting stuck and blockage, and ensuring continuous quantitative feeding.

[0020] (4) After the raw material enters the feeding tube, the second motor assembly drives the linkage shaft connected to it to rotate. Since the gear assemblies on the outside of the two linkage shafts mesh with each other, the two linkage shafts will rotate synchronously in opposite directions and drive the drive rollers connected to them to rotate. The drive rollers are driven by the belt between them and the driven rollers, so that the belts circulate. During the belt movement, the striking rollers that are in contact with its side rotate under the action of friction. The protrusions on the outside of the striking rollers, which are evenly distributed, will intermittently strike the outer wall of the feeding tube. This continuous striking action can effectively prevent the raw material from getting blocked in the feeding tube, further ensuring that the raw material is discharged smoothly from the feeding tube, and ensuring the efficiency and stability of the entire quantitative feeding process.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: As Figures 1-3 and Figure 5 The technical solution shown in the invention provides the following technical solution: a quantitative feeding mechanism for food processing, wherein a feeding bin 2 for feeding is fixedly connected to the upper part of a frame 1, and a feeding pipe 5 is also fixedly connected to the frame 1. A fixing box 4 is fixedly connected to the frame 1, and a discharge hole is provided on the fixing box 4. The fixing box 4 is located between the feeding bin 2 and the feeding pipe 5, and the single discharge hole on the fixing box 4 corresponds to the inlet of the feeding pipe 5. A first motor assembly 3 is fixedly connected to the frame 1. The output end of the motor assembly 3 is fixedly connected to a drive shaft 19, and the drive shaft 19 is disposed through the center of the fixed box 4. A rotating box 7 is fixedly connected to the outside of the drive shaft 19, and the rotating box 7 is located inside the fixed box 4. A feeding cylinder 6 is arranged in a ring on the rotating box 7. The discharge port diameter of the feeding cylinder 6 is smaller than the maximum value of the discharge hole diameter of the fixed box 4. The lower end of the feeding cylinder 6 is in close contact with the fixed box 4. A cleaning plate 18 for cleaning scattered raw materials is fixedly connected to the lower surface of the rotating box 7.

[0025] When quantitative feeding is required, the first motor assembly 3 is started, and its output drives the drive shaft 19 to rotate. The drive shaft 19 is fixedly connected to the rotating box 7, so the rotating box 7 rotates around the drive shaft 19 inside the fixed box 4. The multiple feeding cylinders 6 arranged in a ring on the rotating box 7 also rotate synchronously. When one of the feeding cylinders 6 rotates to the position corresponding to the discharge port of the feeding bin 2, the raw material to be fed stored in the feeding bin 2 will fall precisely into the inside of the feeding cylinder 6 under its own gravity, completing one quantitative feeding. Since the volume of the feeding cylinder 6 is fixed, each feeding... The amount of raw materials is kept consistent, achieving initial quantitative feeding. As the rotating box 7 continues to rotate, when the feeding cylinder 6 containing the raw materials rotates to directly above the discharge hole at the bottom of the fixed box 4, the raw materials in the feeding cylinder 6 can no longer remain in the cylinder because the lower end face of the feeding cylinder 6 is tightly attached to the inner wall of the fixed box 4. Instead, they fall accurately into the feeding pipe 5 located below the fixed box 4, with the inlet corresponding to the discharge hole. This cycle repeats, and through the sequential rotation, receiving, and unloading of multiple feeding cylinders 6, a continuous, uniform, and quantitative feeding process of raw materials is achieved.

[0026] At the same time, the cleaning plate 18, which is fixedly connected to the lower surface of the rotating box 7, also rotates synchronously on the bottom wall of the fixed box 4 under the drive of the rotating box 7. The cleaning plate 18 can promptly sweep away any small amount of raw material debris or residual material that may be scattered on the bottom wall of the fixed box 4 to the vicinity of the discharge hole, thus avoiding the accumulation of raw materials in the fixed box 4 and effectively ensuring the cleanliness of the internal environment of the fixed box 4. It also prevents the accumulation of scattered raw materials from hindering the rotation of the rotating box 7, further ensuring the smoothness and stability of the entire feeding process.

[0027] Example 2: Figures 3-6The present invention provides the following technical solution: a quantitative feeding mechanism for food processing, wherein a striking mechanism is provided inside and on the side of a fixed box 4. The striking mechanism strikes the fixed box 4 by rotating the feeding cylinder 6 contained therein, thereby preventing the feeding from getting stuck. The striking mechanism includes a striking plate 12, which is rotatably connected to the outside of the fixed box 4. A groove 13 is provided at the upper end of the striking plate 12, and an abutment rod 14 is slidably connected inside the groove 13. The groove 13 is inclined, and the upper end of the abutment rod 14... A connecting plate 20 is fixedly connected, and a sliding plate 17 is fixedly connected to the inner side of the connecting plate 20. The sliding plate 17 is slidably disposed on the side of the fixed box 4. A spring 15 is fixedly connected between the outer side of the fixed box 4 and the inner side of the connecting plate 20. The sliding plate 17 can be reset by the spring 15. Both sides of the inner end of the sliding plate 17 are inclined. An abutment plate 16 is fixedly connected to the outer side of the rotating box 7. The outer end of the abutment plate 16 is arc-shaped. When the abutment plate 16 rotates under the action of the rotating box 7, the outer end of the abutment plate 16 presses against the sliding plate 17.

[0028] During the rotation of the rotating box 7, the abutment plate 16 on its side rotates synchronously. When the outer arc of the abutment plate 16 rotates to contact the inclined surface of the inner end of the sliding plate 17, it will generate an outward squeezing force on the sliding plate 17. Since the sliding plate 17 slides through the side of the fixed box 4, under the action of this squeezing force, the sliding plate 17 will drive the connecting plate 20 and the abutment rod 14 fixed on the connecting plate 20 to move away from the center of the fixed box 4. The spring 15 between the connecting plate 20 and the outer side of the fixed box 4 is stretched and stores elastic potential energy. The abutment rod 14 slides in the inclined groove 13 opened at the upper end of the striking plate 12. Due to the inclined setting of the groove 13, the horizontal movement of the abutment rod 14 will be converted into the rotation of the striking plate 12 around its rotation connection point with the fixed box 4, so that... The lower end of the striking plate 12 is lifted away from the outer wall of the fixed box 4. After the abutment plate 16 rotates past the sliding plate 17, the squeezing force of the abutment plate 16 on the sliding plate 17 disappears, and the stretched spring 15 will quickly return to its original state, causing the sliding plate 17, the connecting plate 20 and the abutment rod 14 to quickly reset. During the reset process, the abutment rod 14 slides in the opposite direction in the slide groove 13, causing the striking plate 12 to rotate quickly in the opposite direction. Its lower end will then strike the outer wall of the fixed box 4. Through the continuous rotation of the rotating box 7, the abutment plate 16 will continuously contact and separate from the sliding plate 17, so that the striking plate 12 will intermittently strike the fixed box 4. The vibration generated by the striking effectively prevents the raw material from getting stuck or blocked at the discharge hole of the fixed box 4 or the discharge port of the feeding cylinder 6, ensuring the continuity of quantitative feeding.

[0029] Example 3: Figures 7-9The present invention provides the following technical solution: a quantitative feeding mechanism for food processing, wherein an auxiliary mechanism is further provided on the frame 1, the auxiliary mechanism is located below the feeding tube 5, and the auxiliary mechanism achieves the effect of striking the feeding tube 5 by the rotation of the striking roller 11 included therein, further preventing the raw material from clogging the feeding tube 5. The auxiliary mechanism includes a second motor assembly 21, the second motor assembly 21 is fixedly connected to the lower part of the frame 1, and two sets of linkage shafts 23 are rotatably connected on the frame 1, and one end of each linkage shaft 23 is fixedly connected to the second motor assembly 21, and the linkage... Gear assemblies 22 are fixedly connected to the outer side of shaft 23, and the two sets of gear assemblies 22 mesh with each other. A drive roller 8 is fixedly connected to the other end of the linkage shaft 23. A driven roller 9 is rotatably connected to the frame 1, and the driven roller 9 is located above the drive roller 8. A belt 10 is sleeved between the outer side of the drive roller 8 and the driven roller 9. A striking roller 11 is rotatably connected to the frame 1, and protrusions are evenly distributed on the outer side of the striking roller 11. The side of the striking roller 11 is in contact with the belt 10. The striking roller 11 rotates due to the friction of the belt 10, thereby striking the outer side of the feeding pipe 5.

[0030] After the raw material enters the feeding pipe 5 through the discharge hole of the fixed box 4, to further prevent the raw material from clogging in the feeding pipe 5, the second motor assembly 21 is activated. The output end of the second motor assembly 21 is fixedly connected to one of the linkage shafts 23, so the linkage shaft 23 starts to rotate. Since gear assemblies 22 are fixedly connected to the outer sides of both linkage shafts 23, and the two gear assemblies 22 mesh with each other, when one linkage shaft 23 rotates, it will drive the other linkage shaft 23 to rotate synchronously in the opposite direction through the meshing transmission action of the gear assembly 22. The other ends of both linkage shafts 23 are fixedly connected to drive rollers 8, so the two drive rollers 8 also rotate synchronously in the opposite direction. A driven roller 9 is rotatably connected to the frame 1. The driven roller 9 is located above the drive roller 8. A belt 10 is sleeved between the outer sides of the drive roller 8 and the driven roller 9. Under the action of rotation, the belt 10 begins to perform a cyclic conveying motion. During the movement of the belt 10, the striking roller 11 located on its side contacts the outer surface of the belt 10. Due to the friction of the belt 10, the striking roller 11 begins to rotate around its own rotation axis. Multiple protrusions are evenly distributed on the outer side of the striking roller 11. When the striking roller 11 rotates, these protrusions will periodically contact and strike the outer wall of the feeding pipe 5. This continuous and regular striking action can cause the feeding pipe 5 to vibrate slightly, effectively preventing the raw materials from accumulating and blocking inside the feeding pipe 5 due to mutual squeezing or sticking. This further ensures that the raw materials can be smoothly discharged from the lower end of the feeding pipe 5, thereby ensuring that the entire quantitative feeding mechanism can operate efficiently, stably and smoothly from the receipt of raw materials, quantitative distribution to final discharge.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
