Description

Technical Field

[0001] The utility model relates to the technical field of laver packaging equipment, and more specifically to a laver cutting and palletizing device. Background Art

[0002] After processing, laver will become large pieces of original laver sheets, which need to be further seasoned, divided, palletized, and packaged to become common instant laver.

[0003] For example, the utility model patent with the authorization announcement date of April 26, 2019, the authorization announcement number of CN208790070U, and the name of "Automated Packaging Line for Material Cutting" includes a palletizing mechanism, a material feeding mechanism, a pillow-type packaging machine, and a palletizing station. Cutting knives are arranged on both the first conveying section and the second conveying section of the material feeding mechanism, and the axis of the cutting knife is perpendicular to the conveying direction of its conveying section in the horizontal direction; the first conveying section and the second conveying section are arranged perpendicular to each other in the horizontal direction, and the conveying plane of the second conveying section is lower than the conveying plane of the first conveying section. A pallet mechanism I is arranged at the tail end of the first conveying section. The automated packaging line for material cutting of this utility model can realize packaging integration and full automation from the conveying of the original laver sheet to cutting, palletizing, and packaging, without manual participation, improving packaging efficiency and reducing labor costs.

[0004] In the above-mentioned existing automated packaging line for material cutting, single sheets are cut and then stacked, and after stacking, they are loaded into a tray. Especially after cutting on the first conveying section, it is conveyed in a reversed direction and then cut on the second conveying section, and finally stacking is completed before the palletizing station. The stacked material stack falls into the tray. The stacking and blanking efficiency of this method is relatively slow, and this method only has a good packaging effect for relatively thin original laver sheets. Since it uses a rolling cutting method, when dealing with relatively thick original laver sheets (5g original laver sheets), the rolling cutting method will cause damage to the original laver sheets, and the situation of broken materials is relatively serious. Summary of the Utility Model

[0005] In order to overcome the defects and deficiencies existing in the above-mentioned prior art, the present utility model provides a laver slicing and loading device. The invention object of the present utility model is to solve the problems that when the existing material slicing and loading equipment slices relatively thick original laver sheets, it is easy to cause broken materials, and the slicing and loading efficiency is low. The present utility model includes a separating and supporting mechanism, a tray conveying mechanism and a material conveying mechanism. A stamping and slicing device is arranged on the tray conveying mechanism. The material conveying mechanism conveys the material into the stamping and slicing device, and stacks the material in the stamping and slicing device. After stacking to the set quantity, the stamping and slicing device stamps and slices the stacked material, and the sliced material blocks fall into the trays on the tray conveying mechanism, completing the slicing and loading of the material. The present utility model adopts a stamping and slicing device to slice the stacked original laver sheets into multiple pieces at one time, greatly improving the slicing efficiency. At the same time, the existing rolling cutting method is changed to a stamping and slicing method, which can be applied to relatively thick original laver sheets and avoid the generation of broken materials.

[0026] More preferably, the conveying direction of the tray conveying mechanism is perpendicular to the conveying direction of the feeding tail rack.

[0027] More preferably, the tray conveying mechanism conveys multiple trays side by side.

[0028] Compared with the prior art, the beneficial technical effects brought by the present utility model are as follows:

[0029] 1. The present utility model adopts a stamping and slitting device to cut the laminated seaweed sheets into multiple pieces at one time, greatly improving the slitting efficiency. At the same time, changing the existing rolling cutting method to a stamping and slitting method can be applicable to relatively thick seaweed sheets and avoid the generation of broken materials.

[0030] 2. The present utility model utilizes the slitting units distributed in a "well" shape and the nine stamping blocks distributed in a nine-square grid. When stamping and slitting the seaweed, nine seaweed blocks can be cut at one time, completing the slitting at one time. For relatively thick seaweed, after stacking can be completed in advance and then placed on the flipping and receiving unit, or the stacking of multiple seaweed sheets can be completed on the flipping and receiving unit, and then the stamping unit operates to complete the slitting at one time. Compared with the existing rolling slitting method, the present utility model belongs to one-time stamping and slitting, which can be applicable to relatively thick seaweed, and multiple seaweed sheets can be stacked and stamped together instead of being cut one by one and then stacked, which can improve the slitting and stacking efficiency of seaweed.

[0031] 3. The outer side surface of the slitting knife of the present utility model is set as an inclined surface. When the stamping block performs stamping and cutting, it will spread and separate outward along the inclined surface of the outer side of the slitting knife, widening the spacing between the cut seaweed blocks. This is beneficial for loading the seaweed blocks. Nine trays can be directly placed under the slitting unit. The slope of the outer side surface of the slitting knife is the distance between adjacent trays. In this way, the seaweed blocks obtained by stamping and slitting can directly fall into the trays, completing the slitting and loading of the seaweed sheets, and the efficiency can be greatly improved.

[0032] 4. The stamping unit of the present utility model is connected to the stamping plate through a connecting rod. The nine stamping blocks are driven to move synchronously through the stamping plate and the connecting rod. The stamping block in the middle moves vertically, and the eight stamping blocks on the outside move vertically and also need to expand outward (i.e., move outward along the outer inclined surface of the slitting knife). In this way, the cut seaweed blocks can be dispersed and fall into the trays under the slitting unit respectively, completing the two processes of slitting and loading.

[0033] 5. The utility model sets a connecting plate on the middle connecting rod, and the outer connecting rod is connected to the middle connecting plate through a tension spring, which is conducive to the automatic aggregation of the punching blocks when they move upward. That is, when the punching blocks leave the slitting unit, under the action of the tension spring, the outer punching blocks gather around the middle punching block to wait for the next punching.

[0034] 6. The stamping drive unit of the utility model includes a stamping support frame and a stamping drive component. The stamping drive component provides power for the stamping plate. The stamping support frame supports the stamping drive component on the one hand and provides guide support for the stamping plate on the other hand, so that the stamping unit can operate more stably.

[0035] 7. The turning and receiving unit provided by the utility model has a simple structure and can be automatically reset. Its main function is to temporarily receive the original seaweed sheets when cutting is not performed. It can receive the stacked original seaweed sheets and can also realize the stacking of the original seaweed sheets.

[0036] 8. The utility model further arranges a punching bin on the slitting unit. The arrangement of the punching bin can ensure the sealing above the slitting unit. On the one hand, it ensures the hygiene of the seaweed sheets and avoids the pollution of the seaweed sheets by the outside world. On the other hand, it also ensures that the dust generated when the punching unit punches the seaweed sheets does not escape to the outside world and pollute the equipment components.

[0037] 9. The material receiving unit of the utility model is connected with the material conveying mechanism to receive the original seaweed sheets conveyed by the material conveying mechanism. After the material receiving unit is withdrawn, the original seaweed sheets can fall onto the flipping material receiving unit. The original seaweed sheets can be stacked on the flipping material receiving unit. After stacking to the set number of layers, they can be punched. The seaweed blocks punched once are the seaweed blocks that need to be loaded in a tray, realizing automatic material receiving and stacking, thereby improving the slitting efficiency and tray loading efficiency.

[0038] 10. The slitting unit of the utility model is assembled on a slitting support frame, and the slitting support frame is supported above the tray conveying mechanism, so that the trays conveyed by the tray conveying mechanism are arranged below the slitting unit, corresponding to each slitting area in the slitting unit, and receiving the seaweed blocks obtained after slitting, and can realize automatic material connection, stacking and tray loading, thereby improving the slitting and tray loading efficiency.

[0039] 11. The tray separation mechanism of the present utility model has a higher separation efficiency and a simpler structure compared with the existing reciprocating movement adsorption and separation method of negative pressure suction cups. Specifically, the tray separation mechanism of the present utility model realizes the separation of the tray by the cooperation of a support component and a separation component with different top surface heights. The linear alternation of the support component and the separation component, where the support component is used to support the bottommost tray, and the separation component is used to insert between the edge of the bottommost tray and the upper tray. As the separation component is inserted, the inserted thickness of the separation component also changes, thereby using the separation component to extrude the bottommost tray out of the tray library to complete the separation of the bottommost tray. Its movement is only a simple linear reciprocating movement. Compared with the existing tray separation mechanism, the structure is simpler and the separation action is also simpler. The simplification of the separation action can further improve the separation efficiency. Therefore, the tray separation mechanism of the present utility model has a simple structure, a simplified action, and a high tray separation efficiency.

[0040] 12. The tray separation mechanism of the present utility model is provided with a separation frame, and both the separation component and the support component are assembled on the separation frame, which simplifies the driving structure, can realize the synchronous movement of the separation component and the support component, and also ensures the structural stability of the separation component and the support component.

[0041] 13. The tray library of the present utility model is provided with multiple rows of storage cavities, and the separation frame is provided with multiple groups of support and separation components, which can realize the simultaneous separation of multiple trays and improve the separation efficiency. Using a cylinder as the driving mechanism, the equipment cost is low.

[0042] 14. The tray separation mechanism of the present utility model is provided with convex strips on the top surfaces of the separation part and the support part to prevent the trays from being misaligned.

[0043] 15. The material conveying mechanism of the present utility model trims the seaweed original sheet through the trimming mechanisms provided on two conveying sections, so that the specification of the seaweed original sheet input into the stamping and cutting device is the set standard specification, which is convenient for more uniform cutting of the seaweed original sheet, promotes the same quality of the seaweed blocks in each tray, and effectively controls the packaging quality.

[0044] 16. In the present utility model, the tray conveying mechanism is connected to the feeding tail frame, and the seaweed blocks loaded in the trays can be input into the packaging machine for packaging. The tray conveying mechanism is vertically arranged with the feeding tail frame. Multiple trays can be input into the feeding tail frame at one time. It can be realized that the tray conveying mechanism intermittently provides trays, and the feeding tail frame continuously conveys for packaging. The interval for the feeding tail frame to convey three trays is the interval of the tray conveying mechanism, which effectively matches the conveying efficiency between the tray conveying mechanism and the feeding tail frame.

Detailed implementation manners

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Embodiment 1

[0068] As a preferred embodiment of the present invention, referring to the accompanying drawings of the specification Figure 1 As shown, this embodiment discloses a laver cutting and tray loading device, including a tray separating mechanism 100, a tray conveying mechanism 200, and a material conveying mechanism 300. The tray separating mechanism 100 is used to separate trays and make the separated trays fall on the tray conveying mechanism 200, and a stamping and cutting device 400 is provided on the tray conveying mechanism 200.

[0069] Refer to the attached drawings of the specification Figure 2 and the attached Figure 3 and the attached Figure 4 As shown, the stamping and slitting device 400 includes a stamping unit 402, a stamping drive unit 401, a flipping and receiving unit 404, a receiving unit 425, and a slitting unit 403. The slitting unit 403 is disposed above the tray conveying mechanism 200, the flipping and receiving unit 404 is disposed on the slitting unit 403, the receiving unit 425 is disposed on one side of the slitting unit 403 and corresponds to the tail end of the material conveying mechanism 300. The material conveying mechanism 300 conveys the material onto the receiving unit 425. After the receiving unit 425 is withdrawn from above the flipping and receiving unit 404, the material falls onto the flipping and receiving unit 404. The receiving unit 425 is withdrawn reciprocally multiple times, and the material is stacked on the flipping and receiving unit 404. The stamping unit 402 is disposed above the flipping and receiving unit 404, and the stamping drive unit 401 drives the stamping unit 402 to perform a linear reciprocating motion. When the stamping unit 402 presses down on the material, the flipping and receiving unit 404 flips downward, causing the material to contact the slitting unit 403. The stamping unit 402 and the slitting unit 403 cooperate to slit the material into multiple material blocks, and the slit material blocks respectively fall into the trays 430 conveyed by the tray conveying mechanism 200 below the slitting unit 403.

[0070] As an example of this embodiment, the tray separating mechanism 100 can adopt an existing tray separating mechanism 100. For example, a reciprocating liftable negative pressure suction cup is provided at the bottom of the tray library 101. The negative pressure suction cup rises to suck the lowermost tray 107 in the tray library 101, and the negative pressure suction cup moves downward to suck out the tray 107 from the tray library 101 and place it on the tray conveying mechanism 200.

[0071] Another example is to provide a separating structure at the bottom of the tray library 101. In the initial state, the lowermost tray 107 is supported by the support piece 105 at its edge, thereby supporting all the trays 107 in the tray library 101. When tray 107 separation is required, the cylinder is used to drive the separating piece 106 to insert between the lowermost tray 107 and its upper tray 108. The separating piece 106 supports the edge of the upper tray 108 of the lowermost tray 107. Then the support piece 105 leaves the edge of the lowermost tray 107 and moves between the lowermost tray 107 and its upper tray 108 to support the edge of the upper tray 108 of the lowermost tray 107. The separating piece 106 moves downward to push the lowermost tray 107 to separate from its upper tray 108. After separation, the lowermost tray 107 drops onto the tray conveying mechanism 200, and the separating piece 106 resets to wait for the next separation.

[0072] As an example of this embodiment, the tray conveying mechanism 200 is a conventional existing conveying mechanism. Generally, a drag chain conveying mechanism with a push block is selected, and a conventional conveying structure of a conveying belt can also be adopted, which can be adjusted according to the actual requirements of packaging.

[0073] Furthermore, the tray conveying mechanism 200 can convey multiple trays 430 side by side at one time, which can correspond to the tray separating mechanism 100. For example, the tray separating mechanism 100 separates three trays 430 at one time, and the three trays 430 are arranged in a row on the tray conveying mechanism 200, and the arrangement direction is perpendicular to the conveying direction of the tray conveying mechanism 200.

[0074] As an example of this embodiment, the material conveying mechanism 300 can be a conveying mechanism existing in seaweed packaging machines, that is, a general conveying mechanism in the art. For example, a conveying structure using an O-shaped belt loop, a drag chain conveying mechanism with a push block, or a synchronous belt conveying mechanism can be used.

[0075] As an example of this embodiment, when it is necessary to punch and cut the laminated three-layer seaweed sheets, the material conveying mechanism 300 conveys materials to the receiving unit 425. After the receiving unit 425 receives the materials, it immediately withdraws above the cutting unit 403, so that the materials fall on the flipping receiving unit 404 above the cutting unit 403. By analogy, after stacking three seaweed sheets, the punching drive unit 401 is started to drive the punching unit 402 to move downward to punch and cut the stacked seaweed sheets.

[0076] As an example of this embodiment, the specifications and quantities of the materials after punching and cutting are confirmed according to the size of the seaweed sheets, the requirements of the packaging specifications, etc. For example, if it is punched and cut into one piece, the punching unit 402 and the cutting unit 403 perform corresponding trimming on the seaweed sheets at one time, so that the size of the cut seaweed skin meets the requirements; at this time, the tray conveying mechanism 200 conveys one tray 430 to below the cutting unit 403 each time.

[0077] If it is punched and cut into two pieces, the cutting unit 403 is a horizontally or vertically placed cutting knife 405. Under the action of the cutting unit 403 and the punching unit 402, the seaweed sheets are cut into two pieces. At this time, the tray conveying mechanism 200 conveys two trays 430 side by side to below the cutting unit 403, so that the cut material blocks fall into the trays 430.

[0078] Referring to the above method, it can also be equally divided into four pieces, six pieces, nine pieces, etc. According to the set specification requirements, the specifications and structures of the punching unit 402 and the cutting unit 403 are arranged.

[0079] In this embodiment, a stamping and slitting device 400 is adopted to slit the stacked original laver sheets into multiple pieces at one time, greatly improving the slitting efficiency. At the same time, the existing rolling slitting method is changed to a stamping slitting method, which can be applied to relatively thick original laver sheets and avoid the generation of scraps.

[0080] Embodiment 2

[0081] As another preferred embodiment of this embodiment, this embodiment is a further detailed supplement and elaboration of the technical solution of the present invention on the basis of the above-mentioned Embodiment 1. In this embodiment, the original laver sheet is cut into nine equal parts. At this time, the arrangement mode of the trays conveyed by the tray conveying mechanism under the slitting unit is as Figure 11 shown.

[0082] To ensure that the cut materials can smoothly fall into the nine trays 430 as Figure 11 shown, it is necessary to optimize the slitting unit 403 and the stamping unit 402. Specifically, refer to the attached drawings in the specification Figure 5 , attached Figure 6 , attached Figure 7 , attached Figure 8 , attached Figure 9 and attached Figure 10 shown. The slitting unit 403 includes two horizontal and two vertical slitting knives 405 distributed in a "well" shape. The opposite surfaces of the two horizontally arranged slitting knives 405 are vertical surfaces 406, and the outer surfaces are inclined surfaces 407; the opposite surfaces of the two longitudinally arranged slitting knives are vertical surfaces 406, and the outer surfaces are inclined surfaces 407; the stamping unit 402 includes nine stamping blocks 408 distributed in a nine-square grid, and the nine stamping blocks 408 correspond to the slitting areas 409 divided by the two horizontal and two vertical slitting knives 405 distributed in a "well" shape.

[0083] In this embodiment, when stamping and slitting laver by using the slitting unit 403 distributed in a "well" shape and the nine stamping blocks 408 distributed in a nine-square grid, nine laver blocks can be slit at one time, and the slitting is completed at one time. For relatively thick laver, after stacking can be completed in advance, and then placed on the flipping and receiving unit 404, or multiple laver sheets can be stacked on the flipping and receiving unit 404, and then the stamping unit 402 operates to complete the slitting at one time. Compared with the existing rolling slitting method, the present invention belongs to one-time stamping and slitting, which can be applied to relatively thick laver. Multiple laver sheets can be stacked and stamped together, rather than being cut one by one and then stacked separately, which can improve the slitting and stacking efficiency of laver.

[0084] As an example of this embodiment, the stamping drive unit 401 drives the stamping unit 402 to perform a straight reciprocating motion up and down. The stamping drive unit 401 can be a cylinder, a hydraulic cylinder or an oil cylinder, or a drive structure connected by a motor and a lead screw. Preferably, it is a hydraulic cylinder.

[0085] As another example of this embodiment, when the flipping and material receiving unit 404 is in a horizontal state, it is used to receive the original nori sheet. When performing stamping and cutting, the stamping unit 402 moves downward, acts on the original nori sheet, continues to move downward, drives the original nori sheet to move downward, and the flipping and material receiving unit 404 is forced to flip downward, so that the original nori sheet contacts the cutting unit 403. Under the combined action of the stamping unit 402 and the cutting unit 403, the original nori sheet is cut into nine nori pieces.

[0086] As a preferred embodiment of this embodiment, the bottom area of the stamping block 408 is the same as the area of the cut nori piece, the bottom area of the middle stamping block 408 is the same as the cross-sectional area of the cutting area 409, and is the same as the area of the cut nori piece. The bottom areas of the eight stamping blocks 408 around are greater than or equal to the area of the cut nori piece. When the stamping blocks 408 gather, the combined bottom area of the nine stamping blocks 408 should be greater than or equal to the area of the original nori sheet. This can avoid damage to the original nori sheet. The original nori sheet contacted by the bottom of the stamping block 408 is not stressed. Therefore, when stamping, the nori pieces can be completely retained.

[0087] If the bottom area of the stamping block 408 is different from the area of the cut material piece (mainly smaller than the area of the material piece), it is impossible to ensure the flatness of the edges of each cut nori piece. If there is a gap between the bottom of the stamping block 408 and the cutting knife 405 of the cutting unit 403, the original nori sheet may break at any position within this gap, resulting in uneven cut nori pieces. Therefore, the preferred solution of this embodiment is that the bottom area of the stamping block 408 is the same as the cross-sectional area of the cutting area 409 of the cutting unit 403 and is also the same as the area of the cut nori piece to ensure the flatness of the cut nori pieces.

[0088] As an embodiment of this embodiment, when using the cutting unit 403 distributed in a "well" shape and the nine stamping blocks 408 distributed in a nine-square grid to perform stamping and cutting on nori, nine nori pieces can be cut at one time, and the cutting is completed at one time. For thicker nori, after stacking can be completed in advance and then placed on the flipping and material receiving unit 404, or stacking of multiple nori sheets can be completed on the flipping and material receiving unit 404, and then the stamping unit 402 operates to complete the cutting at one time. Compared with the existing rolling cutting method, the present utility model belongs to one-time stamping and cutting, which is applicable to thicker nori, and multiple nori sheets can be stacked and stamped together, rather than being cut one by one and then stacked, which can improve the cutting and stacking efficiency of nori.

[0089] Refer to the attached drawings of the specification Figure 5 and the attached Figure 6As shown in the figure, the outer side surface of the cutting knife 405 is set as an inclined surface 407. When the stamping block 408 performs stamping and cutting, it will spread and separate outward along the inclined surface 407 of the outer side surface of the cutting knife, increasing the distance between the cut seaweed blocks. This is beneficial for loading and supporting the seaweed blocks. Nine supporting boxes 430 can be directly placed under the cutting unit 403. The slope of the outer side surface of the cutting knife 405 is the distance between adjacent supporting boxes 430. In this way, each seaweed block obtained by stamping and cutting can directly fall into the supporting box 430, completing the cutting and loading of the original seaweed sheet, and greatly improving the efficiency.

[0090] Embodiment 3

[0091] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and elaboration of the technical solution of the present invention based on the above Embodiment 1 or Embodiment 2.

[0092] In this embodiment, the nine stamping blocks 408 of the stamping unit 402 can be driven by separate power sources, that is, nine stamping driving units 401 are required. The nine stamping driving units 401 can be assembled according to the movement trajectories of the stamping blocks 408 they are respectively connected to. By combining the nine stamping driving units 401 to make their actions consistent, it can be achieved, but this structure has a high cost.

[0093] Therefore, considering the cost, this embodiment provides a preferred technical solution. Referring to the attached drawings Figure 2 and the attached Figure 3 As shown, the stamping unit 402 further includes a stamping plate 410 and nine connecting rods 411. The nine connecting rods 411 are respectively connected to the nine stamping blocks 408, and the upper ends of the nine connecting rods 411 are all connected to the stamping plate 410. The upper and lower ends of the eight connecting rods 411 located on the outside are respectively connected to the stamping plate 410 and the stamping block 408 through universal joint bearings 412. The nine stamping blocks 408 are driven to move synchronously by the stamping plate 410 and the connecting rods 411. The stamping block 408 located in the middle moves vertically, and while the eight stamping blocks 408 located on the outside are moving vertically, they also need to expand outward (i.e., move outward along the outer inclined surface 407 of the cutting knife 405). In this way, the cut seaweed blocks can be dispersed and fall into the supporting boxes 430 under the cutting unit 403 respectively, completing the two processes of cutting and loading.

[0094] Further preferably, a connecting disc 413 is provided on the connecting rod 411 located in the middle, and a tension spring is provided between the connecting rod 411 located on the outside and the connecting disc 413. This is beneficial for the automatic aggregation of the stamping blocks 408 when moving upward. That is, when the stamping blocks 408 leave the cutting unit 403, under the action of the tension spring, the outer stamping blocks 408 gather around the middle stamping block 408 for the next stamping.

[0095] Further preferably, referring to the attached drawings of the specification Figure 2 and the attached Figure 3 As shown, the stamping driving unit 401 includes a stamping support frame 414 and a stamping driving member 415 installed above the stamping support frame 414. A stamping guide shaft 416 is provided on the stamping support frame 414, and the stamping plate 410 is slidably assembled on the stamping guide shaft 416; the stamping driving member 415 is connected to the stamping plate 410 to drive the stamping plate 410 to perform linear reciprocating motion along the stamping guide shaft 416. The stamping driving member 415 provides power for the stamping plate 410. The stamping support frame 414 supports the stamping driving member 415 on the one hand and also provides guiding support for the stamping plate 410 on the other hand, so that the stamping unit 402 can operate more stably.

[0096] Embodiment 4

[0097] As another preferred embodiment of the present invention, this embodiment is a further detailed elaboration and supplement to the technical solution of the present invention based on the above-mentioned Embodiment 1, Embodiment 2 or Embodiment 3. In this embodiment, referring to the attached drawings of the specification Figure 7 As shown, the flipping and material receiving unit 404 includes four flipping shafts 417 arranged around the slitting unit 403. The four flipping shafts 417 are all supported by support seats 420 around the slitting unit 403. The flipping shafts 417 rotate relative to the support seats 420, and a number of material receiving and flipping plates 418 extending flat towards the slitting area 409 of the slitting unit 403 are provided on the flipping shafts 417; a return spring 419 is also provided on the flipping shafts 417 to ensure that the flipping shafts 417 and the material receiving and flipping plates 418 are reset after the stamping unit 402 leaves the slitting unit 403. The slitting knife 405 of the slitting unit 403 is fixed by the support seat 420.

[0098] The flipping and material receiving unit 404 has a simple structure and can be automatically reset. Its main function is to temporarily receive the original nori sheets when slitting is not performed, and it can receive the stacked original nori sheets or realize the stacking of the original nori sheets.

[0099] Embodiment 5

[0100] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and elaboration to the technical solution of the present invention based on the above-mentioned Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4. In this embodiment, referring to the attached drawings of the specification Figure 2 and the attached Figure 3As shown, a stamping bin 421 is arranged above the slitting unit 403, and the stamping block 408 of the stamping unit 402 is located at the upper end of the stamping bin 421; the stamping bin 421 is formed by being surrounded by four bin walls 422, wherein one side of the bin wall 422 is a bin door 423 for materials to enter the stamping bin 421; the bin door 423 is driven to open and close by a bin door driving member 424; the bin door 423 is docked with the rear end of the material conveying mechanism 300.

[0101] The chamber wall 422 of the punching chamber 421 is fixed by pins and can be disassembled for easy observation.

[0102] The setting of the stamping bin 421 can ensure the sealing above the cutting unit 403. On the one hand, it ensures the hygiene of the seaweed sheets and avoids external pollution of the seaweed sheets. On the other hand, it also ensures that the dust generated by the stamping unit 402 when stamping the seaweed sheets does not escape to the outside and pollute the equipment components.

[0103] Example 6

[0104] As another preferred embodiment of the utility model, this embodiment is a further detailed supplement and elaboration of the technical solution of the utility model based on the above-mentioned embodiment 1, embodiment 2, embodiment 3, embodiment 4 or embodiment 5. In this embodiment, refer to the attached manual Figure 3 , Attachment Figure 4 And the instruction manual Figure 7 , Attachment Figure 8 , Attachment Figure 9 and attached Figure 10 As shown, a material receiving unit 425 is provided on one side of the slitting unit 403, and the material receiving unit 425 includes a material receiving plate 426 and a material receiving drive assembly 427. The material receiving drive assembly 427 drives the material receiving plate 426 to perform linear reciprocating motion. When the material receiving plate 426 is extended, it is located above the flipping material receiving unit 404. When the material receiving plate 426 is retracted, the material receiving plate 426 leaves the flipping material receiving unit 404 and is located on one side above the flipping material receiving unit 404.

[0105] Further preferably, in order to facilitate material receiving and layout, the material receiving unit 425 is located on the opposite side of the stamping bin 421 where the bin door 423 is provided.

[0106] This embodiment can be docked with the nori sheet conveying mechanism to receive the nori sheet conveyed by the nori sheet conveying mechanism. After the receiving unit 425 is withdrawn, the nori sheet can fall onto the flip receiving unit 404. After the receiving unit 425 is added, the nori sheet can be stacked on the flip receiving unit 404. After stacking to a set number of layers, it can be punched. The nori block punched once is the nori block to be loaded in a tray 430, realizing automatic receiving and stacking, thereby improving the slitting efficiency and tray loading efficiency.

[0107] Further, the slitting unit 403 is assembled on the slitting support frame 428. The feet 429 of the slitting support frame 428 are supported on the support of the tray conveying mechanism 200. The tray 430 conveyed by the tray conveying mechanism 200 passes through below the slitting support frame 428. This facilitates the trays 430 conveyed by the tray conveying mechanism 200 to be arranged below the slitting unit 403, corresponding to the respective slitting areas 409 in the slitting unit 403, receiving the seaweed blocks obtained after slitting, and enabling automatic material receiving, stacking, and tray loading, thereby improving the slitting and tray loading efficiency.

[0108] Embodiment 7

[0109] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and elaboration of the technical solution of the present invention based on the above Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, Embodiment 6, or Embodiment 7. In this embodiment, different from the existing tray separating mechanism 100, this embodiment provides a tray separating mechanism 100 with an optimized structure. Referring to the attached drawings Figure 12 , attached Figure 13 and attached Figure 14 shown, the tray separating mechanism 100 includes a tray library 101, a support assembly 102, a separation assembly 103, and a tray separating drive assembly 104. The support assembly 102 includes two relatively arranged support members 105. The separation assembly 103 includes two relatively arranged separation members 106. The support assembly 102 and the separation assembly 103 are relatively arranged on both sides of the lowermost tray 107 in the tray library 101. The support assembly 102 and the separation assembly 103 are driven by the tray separating drive assembly 104 to perform a linear reciprocating motion relative to the lowermost tray 107. The two support members 105 of the support assembly 102 are respectively used to support the edges at both ends of the lowermost tray 107. The two separation members 106 of the separation assembly 103 are relatively arranged with the two support members 105 of the support assembly 102, and the top surface of the separation member 106 is higher than the top surface of the support member 105. The height difference between the top surface of the separation member 106 and the top surface of the support member 105 is determined by the distance between the edge of the lowermost tray 107 and the edge of the upper tray 108 stacked on the lowermost tray 107. The thickness of the separation member 106 gradually increases along the length direction towards the front end of the tray, and the thickness of the thickest part of the separation member 106 is greater than the distance between the edge of the lowermost tray 107 and the edge of the upper tray 108 stacked on the lowermost tray 107.

[0110] In the initial state, the two support frames support the edges of the lowermost tray 107 in the tray library 101, so that the trays in the tray library 101 are kept within the tray library 101.

[0111] When the lowermost tray 107 is separated, the tray separation driving assembly 104 drives the support assembly 102 and the separation assembly 103 to move along the length direction of the edge supported by the support assembly 102. The support member 105 is gradually withdrawn, and the front end of the separating member 106 is inserted between the edge of the lowermost tray 107 and the edge of the upper tray 108 stacked on the lowermost tray 107. As the separating member 106 continues to be inserted, the bottom surface of the separating member 106 presses against the edge of the lowermost tray 107 to separate the lowermost tray 107 from the upper tray 108. After separation, the tray separation driving assembly 104 drives the support assembly 102 and the separation assembly 103 to reset. The support member 105 supports the edge of the upper tray 108, and the upper tray 108 becomes the lowermost tray 107.

[0112] In this embodiment, the support assembly 102 and the separation assembly 103 with different top surface heights are used in cooperation to realize the separation of the trays. Refer to the attached Figure 16 As shown, the support assembly 102 and the separation assembly 103 alternate linearly. The support assembly 102 is used to support the lowermost tray 107, and the separation assembly 103 is used to be inserted between the edges of the lowermost tray 107 and the upper tray 108. As the separation assembly 103 is inserted, the inserted thickness of the separation assembly 103 also changes accordingly, so that the lowermost tray 107 is extruded out of the tray library 101 by the separation assembly 103 to complete the separation of the lowermost tray 107. Its movement is only a simple linear reciprocating motion. Compared with the existing tray separation mechanism, the structure is simpler and the separation action is also simpler. The simplification of the separation action can further improve the separation efficiency. Therefore, the tray separation mechanism of the present utility model has a simple structure, a simplified action, and a high tray separation efficiency.

[0113] As an implementation manner of this embodiment, refer to the attached Figure 12 and the attached Figure 17 As shown, the tray separation mechanism further includes a separation frame 111. The separation frame 111 is located at the bottom of the tray library 101. The support assembly 102 and the separation assembly 103 are assembled on the separation frame 111. The tray separation driving assembly 104 is connected to the separation frame 111 to drive the separation frame 111 to perform a linear reciprocating motion. Assembling both the separation assembly 103 and the support assembly 102 on the separation frame 111 simplifies the driving structure, enables the synchronous movement of the separation assembly 103 and the support assembly 102, and also ensures the structural stability of the separation assembly 103 and the support assembly 102.

[0114] As an example of this implementation manner, refer to the attached Figure 15 and the attached Figure 17As shown, a set of support components 102 and a set of separation components 103 are oppositely arranged to form a support separation component 112. Multiple sets of support separation components 112 are arranged in parallel on the separation rack 111, and adjacent support separation components 112 share a support member 105 and a separation member 106.

[0115] As an example of this embodiment, refer to the attached drawings of the specification Figure 2 and the attached Figure 3 As shown, the tray library 101 is provided with multiple sets of storage cavities 109 for storing trays, and adjacent storage cavities 109 are separated by a partition 110.

[0116] The tray library 101 is provided with multiple columns of storage cavities 109, and the separation rack 111 is provided with multiple sets of support separation components 112, which can realize the simultaneous separation of multiple trays and improve the separation efficiency.

[0117] A further preferred technical solution is, refer to the attached drawings of the specification Figure 12 and the attached Figure 14 As shown, the tray separation mechanism further includes a tray mounting rack 113. The tray library 101 is assembled on the tray mounting rack 113. A sliding support shaft 114 is provided on the tray mounting rack 113. The separation rack 111 is slidably assembled on the sliding support shaft 114, and the tray separation drive assembly 104 is assembled on the tray mounting rack 113.

[0118] Further preferably, the top surfaces of the separation member 106 and the support member 105 are provided with ridges 115 to prevent the trays from being misaligned.

[0119] Even more preferably, the tray separation drive assembly 104 is a drive cylinder. Using a cylinder as the drive mechanism, the equipment cost is low.

[0120] Embodiment 8

[0121] As another preferred embodiment of the present invention, this embodiment is a further detailed supplement and elaboration of the technical solution of the present invention on the basis of the above Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, Embodiment 6 or Embodiment 7. In this embodiment, refer to the attached drawings of the specification Figure 1 As shown, the material conveying mechanism 300 includes a first conveying section 301 and a second conveying section 302. The first conveying section 301 is perpendicular to the second conveying section 302. Trimming mechanisms 303 are provided on both the first conveying section 301 and the second conveying section 302. The trimming mechanisms 303 are used for trimming the edges of the conveyed materials; the end of the second conveying section 302 is docked with the stamping and cutting device 400.

[0122] In this embodiment, the material conveying mechanism 300 trims the original nori sheets through the trimming mechanisms 303 provided on two conveying sections, so that the specifications of the original nori sheets input into the stamping and cutting device 400 are set to the standard specifications, facilitating more uniform cutting of the original nori sheets, ensuring that the quality of the nori blocks in each tray 430 is the same, and effectively controlling the packaging quality.

[0123] As an example, the trimming mechanism 303 is an existing structure, and an existing rolling cutting mechanism can be adopted, or a stamping trimming structure can be adopted.

[0124] As an implementation manner of this embodiment, the end of the tray conveying mechanism 200 is docked with the feeding tail frame 500 of the packaging machine 600. The trays 430 containing materials are conveyed into the feeding tail frame 500 of the packaging machine 600 and then conveyed into the packaging machine 600 by the feeding tail frame 500 for packaging.

[0125] Preferably, the conveying direction of the tray conveying mechanism 200 is perpendicular to the conveying direction of the feeding tail frame 500.

[0126] More preferably, the tray conveying mechanism 200 conveys multiple trays 430 side by side. At the end of the tray conveying mechanism 200, as the tray conveying mechanism 200 conveys the trays 430 towards the feeding tail frame 500, the spacing between the trays 430 gradually widens, so that the spacing between the trays 430 entering the feeding tail frame 500 is the same as the pitch of the feeding tail frame 500.

[0127] In this embodiment, the tray conveying mechanism 200 is docked with the feeding tail frame 500, and the nori blocks in the loaded trays can be input into the packaging machine 600 for packaging. The tray conveying mechanism 200 and the feeding tail frame 500 are vertically arranged, and multiple trays 430 can be input into the feeding tail frame 500 at one time. It can be realized that the tray conveying mechanism 200 intermittently provides trays 430, and the feeding tail frame 500 continuously conveys for packaging. The interval for the feeding tail frame 500 to convey three trays 430 is the interval of the tray conveying mechanism 200, effectively matching the conveying efficiency between the tray conveying mechanism 200 and the feeding tail frame 500.

[0128] Although the inventive concept of the present invention has been specifically shown and described with reference to the exemplary embodiments of the present invention, those skilled in the art should understand that various changes in form and details can be made without departing from the spirit and scope of the present invention defined by the claims.
