Description

Technical Field

[0001] This invention relates to the field of automatic cooking machine technology, specifically to a device for sequentially cutting the sealing film of a food container and discharging food from a wok for an automatic cooking machine. It is particularly suitable for automated operation scenarios involving cutting the sealing film of sealed food containers containing ingredients, flipping them over to empty the contents, and collecting empty food containers. Background Technology

[0002] With the fast pace of life and rising labor costs, automatic cooking machines are becoming increasingly widely used as intelligent kitchen equipment. In automatic cooking machines, ingredients are typically pre-packaged in containers with multiple compartments, each holding a different type of ingredient. The openings of each compartment are sealed with a plastic film. During cooking, the automatic cooking machine cuts open the film on the container, then flips it over to allow the ingredients to fall into the wok, thus achieving automatic ingredient dispensing.

[0003] To achieve the above functions, several automatic feeding solutions have been proposed in the prior art. For example, one solution uses a combination of a loading tray and a cutting component. By placing the food container upside down on the loading tray, the cutting component moves to cut the lid film, allowing the food to fall into the pot. Another solution uses a combination of a support base, a cutter, and a drive device. The cutter is positioned at the feeding port, and a motor drives the cutter to rotate around the connecting end to cut the food container's plastic wrap. In addition, some solutions use a food container tearing and rotation drive mechanism to tear open the sealing film of the food container and simultaneously drive the food container to rotate, thereby achieving timed and segmented feeding.

[0004] However, all of the above-mentioned existing technical solutions have varying degrees of drawbacks:

[0005] First, existing cutting solutions cannot achieve sequential selective cutting. Current cutting technologies mostly use a single, integrated structure, cutting through the seals of all compartments in the ingredient container in one go, causing all ingredients to fall into the wok simultaneously. However, for a single dish, different ingredients often have different timing and cooking times – for example, ingredients that take longer to cook need to be added first, while those that cook quickly need to be added later. If all ingredients are added at the same time, some will inevitably be overcooked or undercooked, severely impacting the quality of the dish. Although some solutions achieve timed, segmented feeding through film-tearing and rotating mechanisms, the film-tearing method is rotary, resulting in a complex structure and failing to achieve independent, on-demand cutting control between different compartments within the same ingredient container.

[0006] Secondly, the integration of cutting and unloading functions is low, resulting in poor process coordination. In existing solutions, the cutting mechanism and the unloading mechanism are mostly set up independently. After cutting, the material box needs to be transferred to the unloading station, which increases the complexity of the equipment and the potential for failure. In some integrated solutions, cutting and unloading share the same flipping action, making it impossible to control the order of cutting before unloading.

[0007] Third, the removal and collection of empty ingredient containers is not convenient enough. In existing solutions, after the ingredient container has been filled, the empty container usually needs to be manually removed, or an additional container removal drive mechanism is required. The level of automation is low, which affects the continuous operation efficiency of the cooking machine.

[0008] In summary, existing automatic cooking machine feeding devices suffer from several technical defects when applied to the sealing and feeding of multi-compartment food containers. These defects include "inability to selectively cut the sealing film of each compartment in sequence," "low integration of cutting and unloading functions and poor process coordination," and "inconvenience in collecting empty food containers." Therefore, there is an urgent need in this field for a food container sealing film cutting and wok feeding device that can achieve independent cutting of the sealing film of each compartment as needed, integrate cutting and unloading into the same workstation with smooth process coordination, and automatically collect empty food containers. Summary of the Invention

[0009] The purpose of this invention is to provide a device for sequentially cutting the sealing film of a material box and discharging it into a wok, which aims to solve the technical problems in existing automatic cooking machine discharging devices, such as the inability to selectively cut the sealing film of each compartment of the material box in sequence, poor connection between the cutting and discharging processes, and inconvenience in collecting empty material boxes.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A device for sequentially cutting the sealing film of a material box and discharging it into a wok includes a conveyor line. Along the conveying direction, a material storage station, a cutting and discharging area, and a stacking station are sequentially arranged on the conveyor line. The material storage station is located upstream of the conveyor line and is used to store multiple stacked material boxes and push out the bottommost material box one by one. The cutting and discharging area is located on the conveyor line and is equipped with a cutting blade assembly and a flipping mechanism. The cutting blade assembly includes a mounting frame and multiple cutting blades mounted on the mounting frame. Each cutting blade is connected to an independent drive component to drive it to extend or retract independently. The cutting blade assembly is flipped on the cutting and discharging area to cut the sealing film of the material box. The flipping mechanism is located on the cutting and discharging area and is used to flip the entire material box after the cutting blade assembly has completed the film cutting, allowing the material inside to be poured into the wok. The stacking position is located downstream of the cutting and unloading area. A translation station is provided at the bottom of the stacking position. The translation station is connected to a translation drive. The translation drive drives the translation station to move back and forth between a clearance position away from the flipping mechanism and a parallel position close to the flipping mechanism. Before the flipping mechanism operates, the translation station is in the clearance position, maintaining a safe distance from the flipping mechanism. After the flipping mechanism completes the flipping, the translation drive drives the translation station to move to the parallel position. The next material box launched by the material storage station pushes the empty material box that has completed feeding to the translation station. The empty material boxes are stacked and collected at the translation station.

[0012] The specific steps for pushing the empty material box that has been filled with material to the translation station after the next material box is pushed out by the material storage station are as follows: the translation station is connected and aligned with the cutting and unloading area; when the material storage station pushes out the next full material box, the material box containing the material is used as a pusher to simultaneously push the empty material box that has been filled with material on the cutting and unloading area to the translation station.

[0013] Preferably, when the translation station is in the avoidance position, the safe distance between the translation station and the flipping mechanism is greater than 5mm.

[0014] Preferably, one end of the cutter assembly is rotatably connected to a first rotating shaft disposed on the cutting and unloading area, and the cutter flipping drive drives the cutter assembly to flip around the first rotating shaft.

[0015] Preferably, after the cutter flipping drive drives the cutter assembly to flip, the extended cutter of each cutter contacts and cuts the sealing film of the corresponding material box.

[0016] Preferably, each cutter has an independent drive unit that is a cylinder. Each cylinder independently controls the corresponding cutter to extend or retract before the cutter assembly flips. The extended cutter cuts the corresponding compartment seal film after the cutter assembly flips, while the non-extended cutter does not cut, so as to achieve sequential or selective cutting of the seal film of each compartment of the material box.

[0017] Preferably, the cutter has a three-sided serrated structure, used to cut three sides of the sealing film of the material box, and the fourth side of the material box is not cut.

[0018] Preferably, the non-extended cutter leaves a safety gap at the sealing film of the material box, the safety gap being 2mm to 5mm.

[0019] Preferably, one end of the flipping mechanism is fixedly connected to a second rotating shaft disposed on the cutting and feeding area. The second rotating shaft is connected to a material box flipping drive component. The material box flipping drive component drives the second rotating shaft to rotate, thereby causing the flipping mechanism to flip around the second rotating shaft to flip the entire material box into the wok. The flipping mechanism and the cutting blade assembly flip independently.

[0020] Preferably, the inner wall of the flipping mechanism is provided with a guide groove for guiding and limiting the flange of the material box pushed out by the material storage station.

[0021] Preferably, a stacking drive is provided below the translation station, and a pushing platform is provided at the output end of the stacking drive; two hinge blocks are symmetrically provided at the end of the stacking position, the hinge blocks are hinged to the stacking position, the bottom of the hinge blocks are provided with a guide surface, and the distance between the two hinge blocks is less than the outer diameter of the material box; when the stacking drive drives the pushing platform to push the empty material box upward, the empty material box pushes the hinge block upward to rotate and avoid the position via the guide surface, and after the empty material box passes, the hinge block resets under the action of gravity and supports the empty material box, so as to realize the layer-by-layer stacking of empty material boxes; a guide rod is provided across the output end of the stacking position away from the cutting and unloading area, and the guide rod is provided with a ramp, which is used to push the empty material box back to the stacking position when the pushing platform pushes the empty material box.

[0022] The present invention has the following beneficial effects:

[0023] First, it enables sequential and selective cutting of the sealing films in each compartment of the ingredient container. By setting up multiple independently driven cutters, each cutter corresponds to a compartment in the ingredient container, and each cutter can extend or retract independently, thus achieving on-demand cutting of the sealing films in different compartments. During cooking, the cutting order and timing of the sealing films in different compartments can be controlled according to the cooking characteristics of the ingredients, enabling timed ingredient addition and significantly improving the cooking quality of the dishes.

[0024] Secondly, cutting and unloading are integrated into the same workstation, ensuring smooth process transitions. Both the cutting assembly and the flipping mechanism are located on the cutting and unloading area. After the material box arrives at this workstation, the cutting assembly first flips it to complete the sealing and cutting, and then the flipping mechanism flips the entire material box to complete the unloading. The two actions are clearly sequential and closely connected, eliminating the need to transfer the material box between different workstations. The equipment has a compact structure and high reliability.

[0025] Third, cutting and unloading do not interfere with each other. By setting up a translation station and its avoidance position, the translation station is far away from the flipping mechanism before the flipping mechanism starts working, maintaining a safe distance between them. This avoids interference between the translation station and the flipping material box, ensuring the smooth operation of each process.

[0026] Fourth, empty material boxes are automatically ejected and stacked for collection. After the flipping mechanism completes the flipping, the translation station moves to the parallel position. The next full material box pushed out by the material storage station directly pushes the empty material box on the cutting and unloading area to the translation station. The empty material box is then pushed upward by the stacking drive and the pushing platform. With the unidirectional passage function of the hinge block, the empty material boxes are stacked and collected layer by layer. The ejection of empty material boxes and the feeding of full material boxes are completed simultaneously, without the need for an additional ejection drive mechanism. The structure is simple and highly automated.

[0027] Fifth, empty boxes are stacked neatly and reliably. The bottom of the hinge block at the stacking end has a guide surface. When the pushing platform pushes an empty box, the empty box pushes the hinge block upwards via the guide surface to avoid obstruction. Then, the hinge block resets under gravity and supports the empty box, achieving layer-by-layer stacking. The ramp of the guide rod pushes the empty box back to the stacking position during pushing, ensuring a neat stack of empty boxes.

[0028] In summary, this invention forms a complete and systematic solution, from the sequential cutting of the sealing film and the integrated coordination of cutting and unloading to the automatic ejection and stacking collection of empty material boxes. The coordinated cooperation between the various structures ensures the automation, orderliness, and reliability of the automatic cooking machine's material feeding process.

[0045] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention. Example 1: Overall Structure of the Device

[0047] like Figure 1 As shown, the present invention provides a material box sealing film sequential cutting and wok unloading device, including a conveyor line 1. The conveyor line 1 is provided with a material storage station 11, a cutting and unloading area 12 and a stacking position 13 arranged sequentially along the conveying direction.

[0048] The material storage station 11 is located upstream of the conveyor line 1 and is used to store multiple stacked material boxes 2 and push out the bottom material box 2 one by one. The material storage station 11 can adopt the structure described in another invention filed by the applicant on the same day, "A Raw Material Warehouse Feeding Device", or it can adopt other silo structures that can realize the push-out of stacked material boxes 2 one by one.

[0049] The cutting and unloading area 12 is located on the conveyor line 1, and a cutter assembly 3 and a flipping mechanism 4 are mounted thereon. The cutter assembly 3 includes a mounting frame 31 and multiple cutters 32 mounted on the mounting frame 31. Each cutter 32 is connected to an independent drive unit 33 to drive it to extend or retract independently. The cutter assembly 3 is flipped on the cutting and unloading area 12 for cutting the sealing film of the material box 2. The flipping mechanism 4 is located on the cutting and unloading area 12 for flipping the material box 2 as a whole after the cutter assembly 3 has completed the film cutting, so that the material inside the material box 2 can be poured into the wok.

[0050] The stacking station 13 is located downstream of the cutting and unloading area 12, and a translation station 131 is provided at the lower part of the stacking station 13. The translation station 131 is connected to a translation drive 5, which drives the translation station 131 to reciprocate between a clearance position away from the flipping mechanism 4 and a parallel position close to the flipping mechanism 4. Before the flipping mechanism 4 operates, the translation station 131 is in the clearance position, maintaining a safe distance (greater than 5mm) from the flipping mechanism 4. After the flipping mechanism 4 completes the flipping, the translation drive 5 drives the translation station 131 to move to the parallel position. The next material box 2 launched from the material storage station 11 pushes the empty material box 2 that has completed feeding to the translation station 131, where the empty material boxes 2 are stacked and collected. Example 2: Structure of the cutter assembly

[0051] like Figure 2 As shown, the cutter assembly 3 includes a mounting bracket 31 and a plurality of cutters 32 disposed on the mounting bracket 31. The number of cutters 32 corresponds to the number of compartments in the material box 2—for example, if the material box 2 has six compartments, six cutters 32 are provided.

[0052] Each cutter 32 is connected to an independent drive unit 33 (preferably a cylinder), and each independent drive unit 33 can independently control the extension or retraction of the corresponding cutter 32. Before the cutter assembly 3 flips to cut, each independent drive unit 33 can control the corresponding cutter 32 to extend independently by a predetermined distance (preferably 10mm to 15mm) to ensure that after the cutter assembly 3 flips, the blade tip of each cutter 32 approaches and cuts the sealing film surface.

[0053] One end of the cutter assembly 3 is rotatably connected to a first rotating shaft 34 disposed on the cutting and unloading area 12. The cutter assembly 3 is connected to a cutter flipping drive 35 (preferably a cylinder), which drives the cutter assembly 3 to flip around the first rotating shaft 34, so that each cutter 32 contacts and cuts the sealing film of the material box 2.

[0054] Since the extension amount of each cutter 32 is controlled by an independent drive unit 33, it is possible to control which cutters 32 in which compartments extend and which do not extend according to cooking needs, thereby achieving sequential or selective cutting—cutting the compartments of ingredients that are put into the pot first, and cutting the compartments of ingredients that are put into the pot later. Example 3: Structure and cutting method of the cutter

[0055] like Figure 2 As shown, the cutter 32 has a three-sided serrated structure, with its cutting edge being serration 321. The cutter 32 is used to cut three sides of the sealing film of the material box 2, and the fourth side of the material box 2 is not cut.

[0056] Specifically, each compartment of the ingredient box 2 is roughly rectangular, with a sealing film covering the opening of the compartment. The cutter 32 cuts three sides of the sealing film (left, right, and front), leaving the back side uncut. The reason for this design is that after the sealing film is cut on three sides, the food will fall out of the compartment under the action of gravity, while the uncut fourth side keeps the sealing film connected to the ingredient box 2, preventing the sealing film from falling into the wok along with the food.

[0057] After the cutter assembly 3 is flipped over, the non-extended cutter 32 leaves a safe gap at the sealing film of the material box 2. The safe gap is 2mm to 5mm, ensuring that the non-extended cutter 32 will not accidentally cut the sealing film. Example 4: Structure and unloading process of the flipping mechanism

[0058] like Figure 3 As shown, one end of the flipping mechanism 4 is fixedly connected to a second rotating shaft 41 disposed on the cutting and unloading area 12. The second rotating shaft 41 is connected to a material box flipping drive, which drives the second rotating shaft 41 to rotate, thereby causing the flipping mechanism 4 to flip around the second rotating shaft 41 to flip the material box 2 as a whole and pour it into the wok. The flipping mechanism 4 and the cutter assembly 3 flip independently.

[0059] The inner wall of the flipping mechanism 4 is provided with a guide groove 43, which is used to guide and limit the flange 21 of the material box 2 pushed out by the material storage station 11, so as to ensure that the material box 2 is in an accurate position and does not fall off during the flipping process.

[0060] After the cutter assembly 3 completes the sealing cut, the cutter flipping drive 35 drives the cutter assembly 3 to flip and reset in the opposite direction. Subsequently, the material box flipping drive drives the second rotating shaft 41 to rotate, causing the flipping mechanism 4 to flip. The material box 2, which is supported on the flipping mechanism 4, flips along with it and is inverted. The food in the compartment with the sealed film cut falls out of the compartment under the action of gravity and enters the wok below.

[0061] After the material is poured, the material box flipping drive drives the flipping mechanism 4 to flip and reset in the opposite direction, and the cutting and unloading area 12 waits for the arrival of the next material box 2. Example 5: Avoidance and alignment of translation workstations

[0062] like Figure 4-5 As shown, the translation station 131 is connected to the translation drive 5. Before the flipping mechanism 4 operates, the translation drive 5 drives the translation station 131 to a clearance position, maintaining a safe distance of more than 5mm between the translation station 131 and the flipping mechanism 4 to avoid interference between the translation station 131 and the flipping material box 2.

[0063] After the flipping mechanism 4 completes the flipping and unloading and resets, the translation drive 5 drives the translation station 131 to move to the parallel track position, so that the translation station 131 docks with the cutting and unloading area 12. Example 6: The process of empty material box 2 being removed and stacked for collection

[0064] like Figure 6 As shown, after the cutting and unloading area 12 completes the flipping, unloading, and resetting, the material box 2 it carries becomes an empty material box 2.

[0065] Material storage station 11 pushes the next full material box 2 to the cutting and unloading area 12. During the pushing process, the full material box 2 pushes the empty material box 2 on the cutting and unloading area 12 to continue moving forward, pushing the empty material box 2 from the cutting and unloading area 12 to the translation station 131.

[0066] Below the translation station 131 is a stacking drive 6, and the output end of the stacking drive 6 is provided with a pushing platform 61. Two hinge blocks 132 are symmetrically provided at the end of the stacking station 13. The hinge blocks 132 are hinged to the stacking station 13, and the bottom of the hinge blocks 132 is provided with a guide surface 1321. The distance between the two hinge blocks 132 is less than the outer diameter of the material box 2.

[0067] When the stacking drive unit 6 drives the pushing platform 61 to push the empty material box 2 upward, the empty material box 2 pushes the hinge block 132 upward to rotate and avoid the position via the guide surface 1321. After passing through the hinge block 132, the empty material box 2 is reset under the action of gravity and supports the empty material box 2, thereby realizing the layer-by-layer stacking of the empty material boxes 2.

[0068] A guide rod 133 is provided across the output end of the stacking position 13 away from the cutting and unloading area 12. The guide rod 133 is provided with a ramp 1331, which is used to push the empty material box 2 back to the stacking position 13 when the pushing platform 61 pushes the empty material box 2, so that the empty material boxes 2 are stacked neatly. Example 7: The working process of the device

[0069] The working process of the material box sealing film sequential cutting and wok feeding device of the present invention will be described below with reference to the accompanying drawings.

[0070] Step 1: Material box feeding. The material storage station 11 pushes the bottom full material box 2 to the cutting and unloading area 12. The material box 2 is supported on the flipping mechanism 4, and its flange 21 is engaged in the guide groove 43 on the inner side wall of the flipping mechanism 4 to ensure the accurate positioning of the material box 2.

[0071] Step 2: Avoidance at the translation station. The translation drive 5 drives the translation station 131 to move to the avoidance position, maintaining a safe distance of more than 5mm between it and the flipping mechanism 4.

[0072] Step 3: Cutter Pre-Extension. According to the preset menu program, control the independent drive unit 33 of the cutter 32 corresponding to the bins that need to be fed first, so that these cutters 32 extend out a predetermined distance (10mm~15mm). The cutters 32 of the bins that do not need to be fed remain in the retracted state.

[0073] Step 4: Film Cutting. The cutter rotation drive 35 drives the cutter assembly 3 to rotate around the first pivot 34, and each extended cutter 32 contacts and cuts the film in the corresponding compartment. The cutter 32 has a three-sided serrated structure, cutting three sides of the film and leaving the fourth side uncut.

[0074] Step 5: Cutter Reset. After cutting is completed, the cutter reversing drive 35 drives the cutter assembly 3 to reverse and reset.

[0075] Step Six: Flipping and Discharging. The material box flipping drive unit drives the second rotating shaft 41 to rotate, causing the flipping mechanism 4 to flip. The material box 2, which is supported on the flipping mechanism 4, flips and is turned upside down. The ingredients in the compartment with the cut-open seal fall into the wok below under the action of gravity.

[0076] Step 7: Reverse Reset. The material box reversing drive drives the reversing mechanism 4 to reverse and reset.

[0077] Step 8: Repeat steps 3 through 7. According to the menu program, control the cutter 32 of the next batch of ingredients to extend, cut and pour the ingredients, until all ingredients are put into the wok in sequence.

[0078] Step Nine: Alignment of Translation Stations. After the flipping mechanism 4 completes its flipping and resetting, the translation drive 5 drives the translation station 131 to move to the alignment position.

[0079] Step 10: Empty material box 2 exits. After the translation station 131 is in the parallel position, the material storage station 11 pushes out the next full material box 2. The material box 2 containing the material acts as a pusher plate, which abuts against the empty material box 2 on the cutting and unloading area 12 during the movement, and pushes the empty material box 2 to the translation station 131 at the same time.

[0080] Step 11: Stacking empty material boxes. The stacking drive 6 drives the pushing platform 61 to push the empty material boxes 2 upwards. The empty material boxes 2, via the guide surface 1321, push the hinge block 132 upwards to rotate and avoid a misalignment. After passing through, the hinge block 132 resets under gravity and supports the empty material box 2. The ramp 1331 of the guide rod 133 pushes the empty material boxes 2 back to the stacking position 13, making the empty material boxes 2 stacked neatly. Subsequent empty material boxes 2 are stacked sequentially, realizing the automatic collection of empty material boxes 2. Example 8: Application Scenarios

[0081] The material box sealing film sequential cutting and wok feeding device of the present invention can be used in conjunction with the aforementioned raw material hopper feeding device to form a complete feeding and discharging system for an automatic cooking machine.

[0082] In the automatic cooking machine, multiple ingredient containers 2, each containing various ingredients, are stacked in the material storage station 11. The material storage station 11 pushes the ingredient containers 2 one by one to the cutting and feeding area 12. The cutting blade assembly 3 on the cutting and feeding area 12 cuts the sealing film of each compartment in sequence according to the menu program. Then, the flipping mechanism 4 flips the ingredient container 2 as a whole to dump the ingredients into the wok. The empty ingredient container 2 that has been filled is pushed out by the next ingredient container 2 containing material to the translation station 131, where it is pushed to the stacking position 13 by the stacking drive 6 and the pushing platform 61 for automatic stacking and collection.

[0083] Industrial applicability

[0084] The material box sealing and sequential cutting and wok feeding device of the present invention has a compact structure and reliable operation, effectively solving the technical problems of inability to selectively cut in sequence, poor connection between cutting and unloading processes, and inconvenience in collecting empty material boxes 2 during the material box sealing and cutting process. The various mechanisms of the device work together in a coordinated manner, with a high degree of automation and strong adaptability, and can be widely applied to the sealing, cutting, and feeding operations of material boxes 2 used in various automatic cooking machines. Its independent cutting blade control structure enables sequential feeding, improving the quality of food cooking; the design of integrating cutting and unloading at the same station ensures smooth process connection; the avoidance and parallel track design of the translation station ensures that cutting and unloading do not interfere with each other; the linkage design of pushing out empty material boxes 2 from full material boxes simplifies the empty material box 2 exit mechanism; the cooperation between the hinge block and the pushing platform enables automatic layer-by-layer stacking of empty material boxes 2; the guide rod ensures neat stacking, improving the automation and reliability of the device. The above-mentioned structural design has reasonable manufacturing costs, is easy to maintain, and has significant industrial practical value and promotion prospects.

5. The material box sealing film sequential cutting and wok feeding device according to claim 1, characterized in that, Each of the cutters is driven by a cylinder. Each cylinder independently controls the extension or retraction of the corresponding cutter before the cutter assembly flips. The extended cutter cuts the corresponding compartment seal film after the cutter assembly flips, while the non-extended cutter does not cut, thereby achieving sequential or selective cutting of the seal film of each compartment of the material box.

6. The material box sealing film sequential cutting and wok feeding device according to claim 1, characterized in that, The cutter has a three-sided serrated structure and is used to cut three sides of the sealing film of the material box. The fourth side of the material box is not cut.

7. The material box sealing film sequential cutting and wok feeding device according to claim 6, characterized in that, The cutter that does not extend leaves a safety gap of 2mm to 5mm at the sealing film of the material box.

8. The material box sealing film sequential cutting and wok feeding device according to claim 1, characterized in that, One end of the flipping mechanism is fixedly connected to a second rotating shaft disposed on the cutting and feeding area. The second rotating shaft is connected to a material box flipping drive component. The material box flipping drive component drives the second rotating shaft to rotate, thereby causing the flipping mechanism to flip around the second rotating shaft to flip the entire material box into the wok. The flipping mechanism and the cutting blade assembly flip independently.

9. The material box sealing film sequential cutting and wok feeding device according to claim 1, characterized in that, The inner wall of the flipping mechanism is provided with a guide groove for guiding and limiting the flipped edge of the material box pushed out by the material storage station.

10. The material box sealing film sequential cutting and wok feeding device according to claim 1, characterized in that, Below the translation station is a stacking drive, and the output end of the stacking drive is equipped with a pushing platform. Two hinge blocks are symmetrically arranged at the end of the stacking position. The hinge blocks are hinged to the stacking position, and the bottom of the hinge blocks is provided with a guide surface. The distance between the two hinge blocks is less than the outer diameter of the material box. When the stacking drive drives the pushing platform to push the empty material box upward, the empty material box pushes the hinge block upward to rotate and avoid the empty material box through the guide surface. After the empty material box passes, the hinge block resets under the action of gravity and supports the empty material box, so as to realize the layer-by-layer stacking of empty material boxes. A guide rod is provided across the output end of the stacking position away from the cutting and unloading area. The guide rod is provided with a ramp to push the empty material box back to the stacking position when the pushing platform pushes the empty material box.
