French fry carton machine

Abstract

This invention provides a French fry cartoning machine, relating to the technical field of food packaging. The French fry cartoning machine includes a frame body, a carton storage assembly, and a carton-retrieving mechanism. The carton-retrieving mechanism is mounted on an upper mounting plate and is used to move the cartons from the carton storage assembly sequentially below the upper mounting plate. The lifting mechanism of the carton-retrieving mechanism of this invention allows the rotating mounting frame to be raised and lowered, thereby adjusting the height of the suction cup assembly. This allows the suction cup assembly to move the cartons from the upper end to the lower end of the upper mounting plate. After the suction cup assembly adsorbs the cartons, the lifting mechanism detaches the cartons from the carton storage assembly, and the rotating mechanism rotates the suction cup assembly, causing the cartons to rotate so that the opening of the cartons faces upwards, thus completing the carton retrieval. In other words, this carton-retrieving mechanism can move cartons from the high-positioned carton storage assembly to the lower end of the lower mounting plate, facilitating the retrieval of cartons and improving the efficiency of cartoning French fries.

Description

Technical Field

[0001] This invention relates to the technical field of food packaging, and in particular to a French fry boxing machine. Background Technology

[0002] French fries are an essential food in Western restaurants or fast food chains. The cardboard boxes used to pack the fries are three-dimensional boxes. When selling the fried fries, the server first sprinkles salt by hand with a salt shaker, and then uses a fry spatula to pack the fries into different sizes of boxes according to the customer's different requirements. This is labor-intensive, the salting is uneven, and the amount packed is difficult to control. At present, most cardboard box packing machines on the market are flat sheet cardboard box packing machines. That is, the cardboard box is usually folded into a flat shape when it arrives. When it needs to be packed, the cardboard box needs to be folded into a box shape according to the pre-folding curve. These types of packing machines are used in factories or processing plants. There is currently no packing machine that uses three-dimensional cardboard boxes for retailing French fries in Western restaurants. Summary of the Invention

Detailed Implementation

[0097] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0098] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0099] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0100] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0101] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0102] Reference Figures 1-38 The present invention provides a French fry packaging machine, comprising a frame body 100, a box storage assembly 200, and a box picking mechanism 300; the frame body 100 is provided with an upper mounting plate 101, the box storage assembly 200 is disposed on the upper end surface of the upper mounting plate 101, and the box picking mechanism 300 is disposed on the upper mounting plate 101, the box picking mechanism 300 being used to move the paper boxes 900 of the box storage assembly 200 sequentially below the upper mounting plate 101;

[0106] In some embodiments, both the box storage assembly 200 and the box retrieval mechanism 300 are mounted on the frame body 100. The box storage assembly 200 is mounted on the upper end of the upper mounting plate 101, and the box retrieval mechanism 300 is mounted at the box retrieval assembly port 1011.

[0107] Mounting bracket 301 is located on one side of the box assembly port 1011. Lifter 302 is fixedly mounted on mounting bracket 301. Generally, lifter 302 can be a push rod. Rotary mounting bracket 303 is located at the movable end of lifter 302. Rotator 304 is mounted on rotary mounting bracket 303. Rotator 304 can be a motor. Push bracket 305 is located on rotary bracket 304. Rotator 304 can make push bracket 305 rotate.

[0108] A pusher 306 is provided on the pusher bracket 305. The pusher 306 can be a cylinder. The pusher 306 can cause the suction cup assembly 308 provided on the pusher 306 to perform telescopic movement.

[0109] The suction cup assembly 308 generally includes an airway elbow, a suction cup bracket 307, and a suction cup; the suction cup bracket 307 is mounted on the push bracket 305, the airway elbow is mounted on the suction cup bracket 307, and the suction cup is mounted on the airway elbow.

[0110] Reference Figures 3-8 In an optional embodiment, the box assembly 200 includes a rotational power mechanism 201, a rotational support 203, and a plurality of box cylinders 202 disposed on the rotational support 203.

[0111] The rotating bracket 203 is mounted on the rotating power mechanism 201, which rotates the rotating bracket 203. A plurality of boxes 202 are mounted on the rotating bracket 203. The plurality of boxes 202 are evenly arranged along the circumference of the rotating bracket 203.

[0112] The box cylinder 202 is provided with a connector 2023, and the rotating bracket 203 is provided with a connector groove 2031 that matches the connector 2023; the box cylinder 202 is provided with a through hole 2021 arranged in the horizontal direction, and the upper mounting plate 101 is provided with a first sensor assembly 110, which detects whether there is a paper box 900 inside the box cylinder 202 through the through hole 2021;

[0113] A lower limit baffle 2022 is provided inside the box cylinder 202. A plurality of paper boxes 900 are assembled inside the box cylinder 202, and the openings of the paper boxes 900 face downwards. The lowermost paper box 900 abuts against the lower limit baffle 2022. The lower limit baffle 2022 is used to prevent the paper box 900 from detaching from the lower end of the box cylinder 202.

[0114] At least one of the lower openings of the box cylinder 202 faces the box assembly port 1011, and the suction cup assembly 308 is used to pick up the paper box 900 from the box cylinder 202.

[0115] The rotating power mechanism 201 of the box assembly 200 is provided with a rotating support 203, and four box cylinders 202 are generally provided on the rotating support 203; the box cylinders 202 have multiple stacked paper boxes 900, and the openings of the paper boxes 900 face downwards.

[0116] To prevent the paper box 900 from falling off the bottom of the box cylinder 202, a lower limit baffle 2022 is provided inside the box cylinder 202. The lower limit baffle 2022 abuts against the paper box 900, preventing the paper box 900 from moving further downward. When it is necessary to remove the paper box 900 from the box cylinder 202, the suction cup assembly 308 adsorbs the paper box 900 at the bottom of the box cylinder 202, and the pusher 306 moves the paper box 900 toward the pusher, thereby causing the lower end of the paper box 900 to be misaligned with the lower limit baffle 2022.

[0117] Reference Figures 15-20 Since the flange 901 of the second-to-last paper box 900 is not sucked in, the second-to-last paper box 900 is not deformed, and the flange 901 of the second-to-last paper box 900 falls onto the lower limit baffle 2022. The second-to-last paper box 900 and the paper boxes 900 above it will not fall out. The suction cup assembly 308 moves the paper box 900 downward under the push of the lifter 302. After the bottom of the paper box 900 is separated from the box cylinder 202, the paper box 900 can descend under the action of the lifter 302. That is, the lifter 302 moves the paper box 900 from the box assembly port 1011 to the lower end of the upper mounting plate 101. At this time, the rotator 304 causes the rotating mounting bracket 303 to rotate, thereby causing the paper box 900 to rotate 180°, so that the opening of the paper box 900 faces upward.

[0118] The rotating bracket 203 is provided with a plug groove 2031, and the box 202 is provided with a plug member 2023; generally, the box 202 is provided with two plug members 2023, and the rotating bracket 203 is provided with a plug groove 2031 corresponding to the plug member 2023. The plug member 2023 is inserted into the plug groove 2031, so that the box 202 is assembled on the rotating bracket 203.

[0119] A through hole 2021 is provided on the box cylinder 202. The first sensor assembly 110 generally includes an infrared receiver and an infrared transmitter. When there is no paper box 900 in the box cylinder 202, the infrared light emitted by the infrared transmitter can be received by the infrared receiver. At this time, there is no paper box 900 in the box cylinder 202.

[0120] Generally, only one first sensor component 110 detects one of the multiple empty boxes 202. When the first sensor component 110 detects that there is no paper box 900 in the box 202, multiple empty boxes 202 need to be filled with paper box 900 in sequence.

[0121] Reference Figures 9-12 , Figure 29 In an optional embodiment, it further includes a carton rotating mechanism 400 and a weighing and packing mechanism 500; the weighing and packing mechanism 500 is used to pack the French fries into the carton 900 of the carton rotating mechanism 400 according to their weight.

[0133] Reference Figure 13 In an optional embodiment, the shaking mechanism 407 includes a shaking motor 4071, an eccentric wheel, and a housing mounting plate 4072. The shaking motor 4071 is mounted on the rotating disk 404, and the eccentric wheel is disposed at the output end of the shaking motor 4071.

[0134] The box sleeve mounting plate 4072 is disposed on the rotating disk 404, and a first sliding component 4076 is disposed between the box sleeve mounting plate 4072 and the rotating disk 404;

[0135] The box mounting plate 4072 is provided with a first sliding groove, and the eccentric wheel is disposed in the first sliding groove. The eccentric wheel causes the box mounting plate 4072 to reciprocate in the direction restricted by the first sliding component 4076.

[0136] The shaking motor 4071 can rotate the eccentric wheel, which passes through the first slide groove. Through the rotation of the eccentric wheel, the box sleeve mounting plate 4072 reciprocates in one direction, while the first sliding component 4076 restricts the box sleeve mounting plate 4072 to move in one direction, thereby realizing the shaking of the paper box 900.

[0137] Reference Figure 14In an optional embodiment, the shaking mechanism 407 includes a shaking motor 4071, an eccentric wheel, and a housing mounting plate 4072. The shaking motor 4071 is mounted on the rotating disk 404, and the eccentric wheel is disposed at the output end of the shaking motor 4071.

[0138] One end of the box sleeve mounting plate 4072 is provided with a swing rod 4074, and the end of the swing rod 4074 away from the box sleeve mounting plate 4072 is hinged to the rotating disk 404.

[0139] The swing arm 4074 is provided with a second slide groove 4073, and the eccentric wheel is disposed in the second slide groove 4073; a limiting member 4075 is provided on the rotating disk 404, the limiting member 4075 is provided with a side opening 40751, the swing arm 4074 is assembled in the side opening 40751, and the limiting member 4075 is used to restrict the up and down movement of the swing arm 4074.

[0140] One end of the swing arm 4074 is hinged to the rotating disk 404. The eccentric wheel causes the swing arm 4074 to swing, thereby causing the box sleeve mounting plate 4072 to vibrate. In order to make the swing arm 4074 swing in the plane, the swing arm 4074 is set in the side opening 40751 of the limiting member 4075. The limiting member 4075 restricts the vertical movement of the swing arm 4074.

[0141] In an optional embodiment, the box sleeve assembly 408 includes a box sleeve body 4081 and a sleeve 4082; the sleeve 4082 is sleeved on the box sleeve body 4081 and the sleeve 4082 is fixed on the box sleeve mounting plate 4072.

[0142] The lower end of the box sleeve body 4081 is provided with two lower support protrusions 40811, which cooperate to support the paper box 900. A first notch 40813 is provided on the box sleeve body 4081, through which the paper box 900 is removed from the box sleeve body 4081. A detection hole 40812 is provided on the box sleeve body 4081, through which the second sensor assembly 409 detects whether there is a paper box 900 inside the box sleeve body 4081.

[0143] The second sensor assembly 409 includes an infrared emitter and an infrared receiver. When the cardboard box 900 is inserted into the box sleeve body 4081, the infrared receiver cannot receive the infrared light emitted by the infrared emitter, and thus determines that the box sleeve body 4081 contains the cardboard box 900.

[0144] The main body of the box sleeve 4081 has an upper opening, and the paper box 900 is assembled into the main body of the box sleeve 4081 through the upper opening of the main body of the box sleeve 4081; the lower support protrusion 40811 provided at the lower end of the main body of the box sleeve 4081 plays the role of supporting the paper box 900 and preventing the paper box 900 from falling off from the lower end of the main body of the box sleeve 4081.

[0145] To facilitate the placement of the paper box 900 onto the box sleeve body 4081 by the box removal mechanism 300, a first notch 40813 is provided on the box sleeve body 4081. The flange 901 of the paper box 900 placed inside the box sleeve body 4081 corresponds to the first notch 40813, thus facilitating the removal of the paper box 900.

[0146] The sleeve 4082 is fitted over the body 4081 of the box sleeve and is used to connect with the box sleeve mounting plate 4072, thus fixing the box sleeve assembly 408 on the box sleeve mounting plate 4072.

[0147] In an optional embodiment, the weighing and boxing mechanism 500 includes a large funnel assembly 501, a vibratory plate 502, and a boxing assembly 503.

[0148] The large funnel assembly 501 includes a large funnel 5011 and a large funnel support 5012. The large funnel 5011 is disposed on the large funnel support 5012, and the large funnel support 5012 is disposed on the frame body 100.

[0149] The vibratory feeder 502 is located at the lower end of the large funnel 5011, and the vibratory feeder 502 is used to transport the French fries in the large funnel 5011 into the boxing assembly 503.

[0150] The large funnel 5011 is used to receive French fries. The French fries in the large funnel 5011 enter the vibrating plate 502. As the vibrating plate 502 vibrates, the French fries gradually fall off the vibrating plate 502 and fall onto the packaging assembly 503.

[0151] In an optional embodiment, the cartoning assembly 503 includes a material box 5031, a material box support 5032, a cartoning mounting plate 5033, and a cartoning motor 5036;

[0152] The feed box 5031 is used to receive the French fries that fall from the vibrating plate 502, and the feed box 5031 is disposed on the feed box support 5032;

[0153] A weighing sensor 5037 is provided on the frame body 100, and a weighing support frame 5034 is provided on the weighing sensor 5037.

[0154] The boxing mounting plate 5033 is hinged to the weighing support frame 5034, and the boxing motor 5036 is mounted on the boxing mounting plate 5033;

[0155] The cassette support 5032 is mounted on the boxing mounting plate 5033 via a second sliding component 5038; a third sliding groove 50331 is provided on the cassette support 5032, and an eccentric wheel on the boxing motor 5036 is disposed in the third sliding groove 50331; the boxing motor 5036 causes the cassette support 5032 to reciprocate in the direction limited by the second sliding component 5038;

[0156] The weighing support frame 5034 is equipped with a boxing rotary motor 5035, which is connected to the boxing mounting plate 5033 and causes the boxing mounting plate 5033 to rotate.

[0157] The weighing sensor 5037 is mounted on the main frame 100, and the weighing support frame 5034 is mounted on the weighing sensor 5037. The boxing motor 5036 causes the box support 5032 to vibrate through the eccentric wheel, thereby enabling the box 5031 to hold more fries.

[0158] After the weighing sensor 5037 weighs the specified weight of fries, the carton rotation motor 5035 causes the carton mounting plate 5033 to rotate, which in turn causes the cassette 5031 fixed on the carton mounting plate 5033 to rotate, causing the cassette 5031 to flip over and causing the fries to detach from the cassette 5031.

[0159] Reference Figures 21-33 In an optional embodiment, the weighing box mechanism 500 further includes a small funnel assembly 504, which is disposed on the side of the large funnel assembly 501 away from the vibratory plate 502.

[0160] The small funnel assembly 504 includes a small funnel 5041 and a small funnel support 5042. The small funnel support 5042 is disposed on the frame body 100, and the small funnel 5041 is disposed on the small funnel support 5042. The small funnel 5041 is used to receive the French fries poured out from the feed box 5031.

[0161] The rotary driver 402 causes the rotating disk 404 to rotate, causing the box sleeve assembly 408 to move sequentially below the small funnel assembly 504.

[0162] To ensure that the fries falling from the feed box 5031 enter the cardboard box 900, a small funnel assembly 504 is provided above the cardboard box 900. The fries enter the cardboard box 900 through the small funnel 5041, which can prevent the fries from falling and reduce waste.

[0163] Once the cardboard box 900 of one of the box sleeve assemblies 408 is filled with fries, the rotary driver 402 causes the rotary disk 404 to rotate, moving the other box sleeve assemblies 408 below the small funnel assembly 504.

[0164] In an optional embodiment, a spreading mechanism 600 is also included, which includes a spreading bracket 601 and a salt bin assembly 602 and a power assembly 603 disposed on the spreading bracket 601.

[0165] The material spreading bracket 601 is mounted on the main frame 100, and the salt bin assembly 602 is mounted above the material box 5031;

[0166] The power assembly 603 includes a material spreading motor 6031, a drive bracket 6035, a drive plate 6032, and a striking rod 6034; the drive bracket 6035 is disposed at the upper end of the material spreading bracket 601; the material spreading motor 6031 is disposed on the drive bracket 6035.

[0167] The drive plate 6032 is disposed on the side of the drive bracket 6035 away from the spreading motor 6031, and a third sliding component 6036 is disposed between the drive plate 6032 and the drive bracket 6035.

[0168] A fourth slide groove 6033 is provided on the drive plate 6032, and the eccentric wheel of the feeding motor 6031 is disposed in the fourth slide groove 6033; the striking rod 6034 is disposed on the drive plate 6032;

[0169] The salt bin assembly 602 includes a salt bin body 6021, a salt bin cover 6022, a material feeding rod 6023, and a return spring 6024; the salt bin body 6021 is mounted on the material spreading bracket 601.

[0170] A discharge hole is provided at the lower end of the salt tank body 6021, and an upper limit hole is provided on the salt tank cover 6022;

[0171] The feeding rod 6023 includes an upper guide rod 60231, a middle limit rod 60232, and a lower sealing end 60234 arranged sequentially; the upper guide rod 60231 passes through the upper limit hole, the middle limit rod 60232 is disposed in the salt bin body 6021, and the lower sealing end 60234 is used to seal the feeding hole;

[0172] The reset spring 6024 is sleeved on the upper guide rod 60231, and a limit nut 6025 is provided on the upper guide rod 60231. One end of the reset spring 6024 abuts against the limit nut 6025, and the other end abuts against the salt tank cover 6022.

[0173] The return spring 6024 is used to cause the lower sealing end 60234 to move toward the striking rod 6034; the diameter of the middle limiting rod 60232 is larger than the upper limiting hole, and when the middle limiting rod 60232 abuts against the salt tank cover 6022, the lower sealing end 60234 blocks the discharge hole;

[0174] A material-carrying groove 60233 is formed between the lower sealing end 60234 and the middle limiting rod 60232. The material-carrying groove 60233 is used to transport the material inside the salt tank body 6021 to the outside of the salt tank body 6021.

[0175] The sprinkling mechanism 600 is located above the material box 5031. When sprinkling is required, the sprinkling motor 6031 causes the hitting rod 6034 to press down the hitting rod 6023, causing the hitting rod 6023 to move downward. At this time, the lower sealing end 60234 moves away from the feeding hole, and the salt or other seasonings inside the salt bin body 6021 can fall from the feeding hole into the material box 5031, sprinkling salt on the fries inside the material box 5031.

[0176] When the striking rod 6034 moves upward, the lower sealing end 60234 of the material feeding rod 6023 moves downward to the material feeding hole and blocks it under the action of the return spring 6024. Since the middle limit rod 60232 cannot enter the upper limit hole, when the middle limit rod 60232 abuts against the salt tank cover 6022, the lower sealing end 60234 blocks the material feeding hole.

[0177] The material-carrying groove 60233 is located inside the salt bin body 6021. The material inside the salt bin body 6021 enters the material-carrying groove 60233. When the feeding rod 6023 moves downward, the material-carrying groove 60233 moves out from the lower end of the salt bin body 6021, and the material in the material-carrying groove 60233 falls into the material box 5031, thus sprinkling the French fries. This sprinkling mechanism 600 is used for salt, but it can also be used to sprinkle other seasonings, such as cumin.

[0178] Among them, the power component 603 can be connected to the lever 6034 by a cylinder. Such a power component 603 has a simple structure, but requires an additional air source.

[0179] Reference Figure 34 In an optional embodiment, a stacking mechanism 700 is also included. The stacking mechanism 700 includes a robotic arm assembly 701, a gripper 702, and a finger gripper assembly 703. The robotic arm assembly 701 is disposed on the frame body 100, and the gripper 702 is disposed at the end of the robotic arm assembly 701. The finger gripper assembly 703 is disposed on the gripper 702 and is used to grip the paper box 900.

[0180] The gripper assembly 703 includes a wide gripper and a narrow gripper, which work together to grip the cardboard box 900; thus, the stacking mechanism 700 can remove the cardboard box 900 from the box sleeve assembly 408 and place it onto the finished product rack assembly 800.

[0181] Generally, the finger clamping component 703 clamps the flange 901 of the paper box 900, and since the flange 901 of the paper box 900 corresponds to the first notch 40813, the body of the box sleeve 4081 does not affect the finger clamping component 703 clamping the paper box 900.

[0182] Among them, the robotic arm component 701, gripper 702 and finger gripper component 703 are all existing technologies.

[0183] Reference Figures 35-37 In an optional embodiment, it also includes a finished product rack assembly 800, wherein the stacking mechanism 700 places the cardboard box 900 on the cardboard box rotating mechanism 400 onto the finished product rack assembly 800;

[0184] The finished product rack assembly 800 includes a finished product shelf 803, a finished product support frame 801, and a third sensor assembly 804. The finished product shelf 803 is provided with at least one placement slot 802. The third sensor assembly 804 is provided at the first end of the placement slot 802. The stacking mechanism 700 places the cardboard box 900 at the second end of the placement slot 802, and the height of the first end is lower than the height of the second end.

[0185] The finished product support frame 801 is mounted on the main body of the frame 100.

[0186] The finished product support frame 801 is set on the main body of the frame 100. Multiple placement slots 802 are set on the finished product support frame 801, and the first end of each placement slot 802 is lower than the second end. Generally, one end of the extension direction of the placement slot 802 is the first end and the other end is the second end. A third sensor assembly 804 is set at the first end of the placement slot 802. The third sensor assembly 804 is used to monitor whether the placement slot 802 is full of cardboard boxes 900.

[0187] Paper boxes 900 are sequentially placed into the second end of the placement slot 802 and move sequentially towards the first end. When the sensor assembly detects a paper box 900, it indicates that the placement slot 802 is full of paper boxes 900.

[0188] The width of the placement slot 802 matches the width of the cardboard box 900. When the cardboard box 900 is placed in the placement slot 802, the cardboard box 900 generally only moves along the first end of the placement slot 802.

[0189] One box tube 202 can correspond to one size of paper box 900, and each medium-sized paper box 900 can correspond to one placement slot 802, thereby meeting the requirements of different sizes of paper boxes 900 to hold different amounts of fries.

[0190] In an optional embodiment, the angle between the line connecting the first end and the second end and the horizontal plane is α, where 2°≤α≤7°.

[0191] In order to enable the cardboard box 900 to move more smoothly along the placement groove 802, the bottom of the placement groove 802 has a certain angle with the horizontal surface. This makes it easier for the cardboard box 900 to move within the placement groove 802 and ensures that the cardboard box 900 is not easily detached from the placement groove 802 without external force.

[0192] The French fry packaging machine is also equipped with casters and side guards.

[0193] The lifting mechanism 302 of the French fry packaging machine provided by this invention can raise and lower the rotating mounting frame 303, thereby adjusting the height of the suction cup assembly 308. This allows the suction cup assembly 308 to move the paper box 900 from the upper end of the upper mounting plate 101 to the lower end of the upper mounting plate 101. After the suction cup assembly 308 adsorbs the paper box 900, the lifting mechanism 302 causes the paper box 900 to detach from the box storage assembly 200, and the rotating mechanism 304 rotates the suction cup assembly 308, thereby causing the paper box 900 to rotate so that the opening of the paper box 900 faces upward, thus completing the box retrieval. In other words, the box retrieval mechanism 300 can move the paper box 900, which is located at a high position in the box storage assembly 200, to the lower end of the lower mounting plate, which facilitates the retrieval of the paper box 900 and improves the efficiency of packaging French fries in the paper box 900.

[0194] The box-retrieving mechanism 300 of this French fry boxing machine can automatically retrieve the paper box 900 from the box storage assembly 200 and place the paper box 900 at a designated position on the paper box rotating mechanism 400. The paper box rotating mechanism 400 moves the box sleeve assembly 408 containing the paper box 900 below the small funnel assembly 504. The fried French fries are placed into the large funnel assembly 501, and the vibrating plate 502 moves the French fries into the boxing assembly 503. At the same time, the seasoning dispensing mechanism 600 can sprinkle seasonings, such as salt and pepper, into the seasoning box 5031. The weighing sensor 5037 accurately weighs the French fries in the seasoning box 5031. When the weight of the French fries in the seasoning box 5031 meets the requirements, the seasoning box 5031 is flipped, and the French fries in the seasoning box 5031 are poured into the small funnel assembly 504. The small funnel assembly 504 puts the French fries into the paper box 900, thus completing the boxing of the French fries in the paper box 900.

[0195] The weighing sensor 5037 can be set according to different needs, and the spreading mechanism 600 can adjust the amount of spreading according to different specifications, so that it can pack French fry boxes of different specifications at the same time, overcoming the shortcomings of manual packing, such as high labor intensity, uneven spreading, and difficulty in controlling the packing amount.

[0196] The rotary driver 402 rotates the rotary disk 404, moving the empty box sleeve assembly 408 below the small funnel assembly 504. The stacking mechanism 700 then moves the cardboard box 900 containing the fries onto the finished product rack assembly 800, thus completing the automatic weighing, automatic weighing, and automatic placement of the fries. Because the weighing is performed using the weighing sensor 5037, it is ensured that the fries in the cardboard box 900 meet the requirements and that the consistency of the product is guaranteed.

[0197] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
