Description

Technical Field

[0001] This invention belongs to the field of food packaging technology, and specifically relates to an automatic food packaging device. Background Technology

[0002] Food packaging is a key process in food processing and distribution. It refers to the operation of sealing processed food materials into packaging bags that meet food safety standards according to preset specifications.

[0003] Chinese Patent Application No. 202322359989.2 discloses an automatic weighing and bagging device for bulk food, including a base, a support plate on one side of the top of the base, a movable groove on the support plate, a connecting plate and a weighing device respectively above and below the movable groove, an opening and closing weighing hopper mechanism on one side of the connecting plate, a auger conveyor on the top of the support plate, a cylinder in the middle of the top of the base, and a rotating support mechanism on the other side of the top of the base. Several height-adjustable bag placement mechanisms are arranged circumferentially along the upper edge of the rotating support mechanism. During weighing and bagging, the auger conveyor transports the bulk food to the opening and closing weighing hopper mechanism. The weighing hopper mechanism weighs the contents of the opening and closing weighing hopper until the weight reaches the target. The auger conveyor then stops conveying the contents, and several bags are placed in several height-adjustable bag placement mechanisms. A rotating support mechanism rotates one of the bags to a position below the opening and closing weighing hopper mechanism. A cylinder raises the height-adjustable bag placement mechanism of that bag to the position of the opening and closing weighing hopper mechanism, opening the mechanism. Bulk food is then loaded into the bags. The cylinder lowers the height-adjustable bag placement mechanism of that bag to the position of the opening and closing weighing hopper mechanism. The above steps are repeated until all bulk food is bagged.

[0020] 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. Example 1

[0021] This invention provides the following technical solution: an automatic food bagging device, comprising: a material box 2, a drive platform 5, and a base 1 arranged sequentially from top to bottom; a connected feed inlet 3 fixedly connected to the top of the base 1; a plurality of connected discharge outlets 6 evenly spaced along the circumference at the bottom of the material box 2; the material box 2 and the drive platform 5, as well as the drive platform 5 and the base 1, are respectively connected by a plurality of support columns 4 evenly spaced along the circumference, the number of support columns 4 being the same as the number of discharge outlets 6 and staggered in position; a plurality of downwardly inclined discharge channels 7 evenly spaced along the circumference between the material box 2 and the drive platform 5, the number of discharge channels 7 being the same as the number of discharge outlets 6 and corresponding in position; and a plurality of distance measuring mechanisms evenly spaced along the circumference on the outer side of the drive platform 5, the number of distance measuring mechanisms being the same as the number of discharge channels 7. Furthermore, the positions below the discharge channel 7 correspond one-to-one with the discharge channel 7. Several collection boxes 8 are evenly spaced along the circumference of the outer side of the drive platform 5. The number of collection boxes 8 is the same as the number of distance measuring mechanisms and they are located below the distance measuring mechanisms and correspond one-to-one with the distance measuring mechanisms. A flipping drive mechanism is installed between the collection boxes 8 and the drive platform 5 to drive the material in the collection boxes 8 to flip when the distance measurement reaches the standard. A rotation drive mechanism is installed between the discharge channel 7 and the flipping mechanism to drive the discharge channel 7 to rotate to a horizontal position when the collection boxes 8 flip. A processor 9 is fixedly connected to the outer wall of the drive platform 5. The distance measuring mechanism and the flipping drive mechanism are electrically connected to the processor 9. Several bag clamping mechanisms are evenly spaced along the circumference of the top of the base 1. The number of bag clamping mechanisms is the same as the number of collection boxes 8 and their positions correspond one-to-one.

[0022] See appendix Figure 1-2 Before the equipment can bag food materials, it opens several bags separately through several clamping mechanisms. When the equipment bags food materials, the materials enter the material box 2 through the feed inlet 3. The materials in the material box 2 are discharged through several outlets, and the discharged materials fall onto several discharge channels 7. They fall along the inclined arc of the discharge channels 7 into several collection boxes 8. The processor 9 controls several distance measuring mechanisms to start, and measures the accumulation distance of the materials collected in the collection boxes 8 until a set value is reached. Then, the processor 9 controls the flipping drive mechanism to start, and the flipping drive mechanism drives the collection boxes 8 to flip. At the same time, the collection boxes 8 are driven by the rotation drive mechanism. Several discharge channels 7 rotate, and when several collection boxes 8 are flipped to their limit, the material collected in the collection boxes 8 is poured into several open bags. At this time, several discharge channels 7 rotate to a horizontal position to block several discharge ports 6 and stop discharging. The material is poured out of several collection boxes 8. The flipping drive mechanism drives several collection boxes 8 to reset. At the same time, the rotation drive mechanism drives several discharge channels 7 to reset. The material collection is repeated. During the material collection process at the material discharge port 6, the bag collection and bag release equipment are coordinated to complete the bag collection and bag release after the material is bagged. This process is repeated until the material is bagged. In the above process, the distance between the discharge channel 7 and the collection box 8 is precisely designed to ensure that the material discharged from the discharge channel 7 can enter the collection box 8. At the same time, the trough of the discharge channel 7 is precisely designed to ensure that the material in the trough will not spill during the rotation of the discharge channel 7.

[0023] Specifically, the ranging mechanism includes a mounting base 101 fixed to the outer wall of the drive table 5. A rangefinder 102 is fixed inside the mounting base 101. The detection head of the rangefinder 102 does not extend out of the discharge end of the discharge channel 7, but extends into the collection box 8. The rangefinder 102 is electrically connected to the processor 9.

[0024] See appendix Figure 2 and 3 The distance measuring mechanism is controlled by the processor 9 to start the distance measuring instrument 102. The distance measuring instrument 102 measures the accumulation distance of the material collected in the collection box 8 to determine whether the material collected in the collection box 8 has reached the set value.

The screw 205 is connected to the lower horizontal mounting plate 207 via a bearing at its bottom end. The top end of the screw 205 extends through the upper horizontal mounting plate 207 and is connected to the upper horizontal mounting plate 207 via a bearing through the through section. A movable seat 208 is connected to the screw 205 between the upper and lower horizontal mounting plates 207 via a transmission nut.

Several first gears 202 mesh with the outer rack 204. The first motor 201 is electrically connected to the processor 9.

[0026] See appendix Figure 1 and 4The flipping drive mechanism is controlled by the processor 9 to start the first motor 201. The first motor 201 drives the output shaft to rotate. The output shaft of the first motor 201 drives the connected screw 205 to rotate. The connected screw 205 drives the connected first gear 202 to rotate. The connected first gear 202 drives the meshing external rack 204 to rotate. The external rack 204 drives the other meshing first gears 202 to rotate. The other first gears 202 drive the connected screw 205 to rotate. During the rotation of the screw 205, the moving seat 208 moves on the screw 205. During the movement of the moving seat 208, the moving rack 209 moves. During the movement of the moving rack 209, the meshing second gear 211 rotates. The second gear 211 drives the connected connecting shaft 210 to rotate. The connected connecting shaft 210 drives the connected collection box 8 to rotate, so as to realize the flipping drive of the collection box 8. The processor 9 controls the forward and reverse rotation of the first motor 201 to control the tilting and unloading or tilting and resetting of the collection box 8.

[0027] Specifically, the rotation drive mechanism includes two connecting seats 301 symmetrically fixed to the bottom of the material box 2, a follower seat 306 connected to two screws 205 on both sides of each collection box 8 via a transmission nut, and two sliding grooves 304 symmetrically opened on the outer wall of the discharge channel 7.

The follower seat 306 is located above the first gear 202. Two follower frames 305 are symmetrically fixed to the top of the follower seat 306. The two follower frames 305 are located on both sides of the discharge channel 7. The two follower frames 305 are respectively fixed to sliders 303 close to each other on the side wall. The two sliders 303 extend into the two sliding grooves 304 for sliding connection.

[0030] See appendix Figure 1 and 5 The bag clamping mechanism rotates the two bag support arms 404 in a direction that brings them closer together, so that the two bag support arms 404 are in a horizontal state with the base 1. At this time, the state of the four torsion springs 402 changes. The bag body is placed on the base 1 between the two bag support arms 404. The bag opening is flipped so that the bag body is fitted between the two bag support arms 404. The two bag support arms 404 are released and reset under the reset action of the four torsion springs 402, thus opening the bag body. Example 2

[0031] The difference between this embodiment and Embodiment 1 is that: Specifically, the material box 2 is equipped with a feeding mechanism, which includes a second motor 503 fixed to the bottom of the drive platform 5.

The output shaft of the second motor 503 drives the feeding shaft 502 to rotate. The feeding shaft 502 drives the feeding plate 501 to rotate. The rotating feeding plate 501 can push the material in the material box 2 to several discharge ports 6 so that the material can be discharged faster. Example 3

[0033] The difference between this embodiment and embodiment two is that: Specifically, the drive platform 5 is equipped with a feeding auxiliary mechanism, which includes an upper central drive cavity 601 inside the drive platform 5, an upper side drive cavity 602 outside the upper central drive cavity 601 inside the drive platform 5, several drive shafts 608 connected circumferentially between the upper central drive cavity 601 and the upper side drive cavity 602 by bearings, and several vertical striking holes 607 circumferentially spaced at the top of the drive platform 5.

[0034] See appendix Figure 2 , 6 And 7, the feeding auxiliary mechanism drives the second conical wheel 610 to rotate via the rotating feeding shaft 502. The second conical wheel 610 drives a plurality of meshing first conical wheels 609 to rotate. The plurality of first conical wheels 609 drive a plurality of drive shafts 608 to rotate. The plurality of drive shafts 608 drive a plurality of first incomplete gears 606 to rotate. When the rotating plurality of first incomplete gears 606 rotate to mesh with a plurality of vertical racks 611, the plurality of first incomplete gears 606 drive the plurality of vertical racks 611 to move upward. If The vertical rack 611 drives several vertical striking blocks 605 to move upward on several vertical fixed columns 603. Several vertical springs 604 are stretched. When the vertical striking blocks 605 move to their limit position, they strike several discharge channels 7. When the rotating first incomplete gears 606 rotate to the point where they no longer mesh with the vertical rack 611, the vertical striking blocks 605 are reset under the reset action of the vertical springs 604. The above steps are repeated to strike several discharge channels 7, assisting the discharge channels 7 to discharge materials and avoid blockage. In the above process, the height of the vertical fixing column 603 and the vertical striking block 605 is precisely designed. When the vertical striking block 605 moves to its limit, it does not detach from the vertical fixing column 603. Example 4

The horizontal springs 705 are fixed to the horizontal striking blocks 706 and support seats 704 at both ends. The number of horizontal striking holes 708 is the same as the number of horizontal striking blocks 706 and their positions correspond one-to-one.

[0036] See appendix Figure 2 , 8 In step 9, the material feeding auxiliary mechanism drives the third gear 703 to rotate via the rotating material feeding shaft 502. The third gear 703 drives the meshing fourth gears 710 to rotate, which in turn drives the follower shafts 702 to rotate. The follower shafts 702 drive the second incomplete gears 709 to rotate. When the rotating second incomplete gears 709 rotate to mesh with the horizontal racks 711, the horizontal racks 711 drive the horizontal striking blocks 706 to move outward on the horizontal fixed columns 707, stretching the horizontal springs 705. When the horizontal striking blocks 706 move outward to their limit position, they strike the collection boxes 8. When the rotating second incomplete gears 709 rotate to no longer mesh with the horizontal racks 711, the horizontal striking blocks 706 reset under the reset action of the horizontal springs 705. The above steps are repeated to strike the collection boxes 8, assisting the material in feeding from the collection boxes 8, avoiding uneven material surface and reducing the measurement accuracy of the rangefinder 102.
