[0008] Further preferably, the bottom area of the stamping block is the same as the area of the corresponding material block to be cut.

[0009] Further preferably, the stamping unit further includes a stamping plate and nine connecting rods. The nine connecting rods are respectively connected to the nine stamping blocks. The upper ends of the nine connecting rods are all connected to the stamping plate. The upper and lower ends of the eight outer connecting rods are respectively connected to the stamping plate and the stamping block through universal joint bearings.

[0010] Even more preferably, a connecting disc is provided on the middle connecting rod, and a tension spring is provided between the outer connecting rod and the connecting disc.

[0011] Even more preferably, the stamping driving unit includes a stamping support frame and a stamping driving member installed above the stamping support frame. A stamping guide shaft is provided on the stamping support frame, and the stamping plate is slidably assembled on the stamping guide shaft; the stamping driving member is connected to the stamping plate and drives the stamping plate to perform a linear reciprocating motion along the stamping guide shaft.

[0012] Further preferably, the flipping and material receiving unit includes four flipping shafts arranged around the slitting unit. The four flipping shafts are all supported by support members around the slitting unit. The flipping shafts rotate relative to the support members, and a plurality of material receiving and flipping plates extending horizontally towards the slitting area of the slitting unit are provided on the flipping shafts; a return spring is also provided on the flipping shafts to ensure that the flipping shafts and the material receiving and flipping plates return to their original positions after the stamping unit leaves the slitting unit.

[0013] Even more preferably, the slitting knife of the slitting unit is fixed by the support member.

[0014] Further preferably, a stamping chamber is provided above the slitting unit, and the stamping blocks of the stamping unit are located at the upper end inside the stamping chamber; the stamping chamber is surrounded by four chamber walls, and one of the chamber walls is a chamber door for materials to enter the stamping chamber; the chamber door is driven by a chamber door driving member to open and close.

[0015] Further preferably, a material receiving unit is provided on one side of the slitting unit. The material receiving unit includes a material receiving plate and a material receiving driving assembly. The material receiving driving assembly drives the material receiving plate to perform a linear reciprocating motion.

[0016] Even more preferably, the material receiving unit is located on the opposite side of the stamping chamber where the chamber door is provided.

[0017] Further preferably, the slitting unit is assembled on a slitting support frame, and a tray conveying channel is formed between the feet of the slitting support frame. The material blocks stamped and slit by the stamping unit fall into the trays in the tray conveying channel.

[0018] Compared with the prior art, the beneficial technical effects brought by the present utility model are as follows:

[0019] 1. The utility model utilizes the slitting units distributed in a "well" shape and nine stamping blocks distributed in a nine-square grid. When stamping and slitting seaweed, nine seaweed pieces can be slit at one time, and the slitting is completed at once. For relatively thick seaweed, it can be stacked in advance and then placed on the flipping and receiving unit, or the stacking of multiple seaweed pieces 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 utility model belongs to one-time stamping slitting, which is applicable to relatively thick seaweed. Multiple seaweed pieces can be stacked and stamped together, rather than being cut separately one by one and then stacked, which can improve the slitting and stacking efficiency of seaweed.

[0020] 2. The outer side surface of the slitting knife of the 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, increasing the distance between the slit seaweed pieces. This is beneficial for the loading and supporting of the seaweed pieces. 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 pieces obtained by stamping and slitting can directly fall into the trays, completing the slitting and loading of the original seaweed sheet, and the efficiency can be greatly improved.

[0021] 3. The stamping unit of the utility model is connected to the stamping plate through a connecting rod. The stamping plate and the connecting rod drive the nine stamping blocks to move synchronously. The stamping block in the middle moves vertically, and the eight stamping blocks on the outside, while moving vertically, also need to expand outward (i.e., move outward along the outer inclined surface of the slitting knife). In this way, the slit seaweed pieces can be dispersed and fall into the trays under the slitting unit respectively, completing the two processes of slitting and loading.

[0022] 4. The utility model is provided with a connecting disc on the middle connecting rod, and the outer connecting rods are connected to the middle connecting disc through tension springs, which is beneficial for the automatic aggregation of the stamping blocks when moving upward. That is, when the stamping blocks leave the slitting unit, under the action of the tension springs, the outer stamping blocks gather around the middle stamping block for the next stamping.

[0023] 5. The stamping drive unit of the utility model includes a stamping support frame and a stamping drive member. The stamping drive member provides power for the stamping plate. The stamping support frame supports the stamping drive member on the one hand and also provides guiding support for the stamping plate on the other hand, so that the stamping unit can operate more stably.

[0024] 6. The flipping and receiving unit provided by the utility model has a simple structure and can automatically reset. Its main function is to temporarily receive the original seaweed sheet when no slitting is carried out. It can receive the stacked original seaweed sheets and can also realize the stacking of the original seaweed sheets.

[0025] 7. 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.

[0026] 8. The material cutting device of the utility model is also provided with a material receiving unit, which can be connected with the seaweed sheet conveying mechanism to receive the seaweed sheet conveyed by the seaweed sheet conveying mechanism. After the material receiving unit is withdrawn, the seaweed sheet can fall onto the flipping material receiving unit. After the addition of the material receiving unit, the seaweed sheet can be stacked on the flipping material receiving unit. After stacking to the set number of layers, it can be stamped. The seaweed block obtained by one-time stamping is the seaweed block that needs to be filled in a tray, realizing automatic material receiving and stacking, thereby improving the slitting efficiency and tray loading efficiency.

[0027] 9. The slitting unit of the utility model is assembled on a slitting support frame, and a tray conveying channel is arranged under the slitting support frame. The tray can be conveyed from the tray conveying channel to the bottom of the slitting unit, corresponding to each slitting area in the slitting unit, and receiving the seaweed blocks obtained after slitting, which can realize automatic material connection, stacking and tray loading, thereby improving the slitting and tray loading efficiency.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0040] Embodiment 1

[0041] As a preferred embodiment of the present utility model, referring to the attached drawings of the specification Figure 1 and the attached Figure 2 As shown, this embodiment discloses a material cutting device, including a stamping drive unit 1, a stamping unit 2, a slitting unit 3 and a flipping material receiving unit 4. The flipping material receiving unit 4 is located above the slitting unit 3 and is used to support the material to be slit. The stamping unit 2 is arranged above the flipping material receiving unit 4. The stamping drive unit 1 drives the stamping unit 2 to perform a linear reciprocating motion, punches the material on the flipping material receiving unit 4 towards the slitting unit 3, and cooperates with the slitting unit 3 to slit the material to be slit into several material blocks; the flipping material receiving unit 4 is driven to flip by the stamping unit 2 when the stamping unit 2 punches, and the material falls on the slitting unit 3.

[0042] Referring to the attached drawings of the specification Figure 4 and the attached Figure 5As shown in the figure, the slitting unit 3 includes two horizontal and two vertical slitting knives 5 distributed in a "well" shape. The opposite faces of the two horizontally arranged slitting knives 5 are vertical surfaces 6, and the outer sides are inclined surfaces 7; the opposite faces of the two longitudinally arranged slitting knives are vertical surfaces 6, and the outer sides are inclined surfaces 7.

[0043] Refer to the attached drawings of the specification Figure 6 As shown in the figure, the stamping unit 2 includes nine stamping blocks 8 distributed in a nine-square grid. The nine stamping blocks 8 correspond to the slitting areas 9 divided by two horizontal and two vertical slitting knives 5 distributed in a "well" shape.

[0044] As an example of this embodiment, the stamping drive unit 1 drives the stamping unit 2 to perform a linear reciprocating motion up and down. The stamping drive unit 1 can be a cylinder, a hydraulic cylinder or an oil cylinder, or a drive structure with a motor connected to a lead screw. Preferably, it is a hydraulic cylinder.

[0045] As another example of this embodiment, when the flipping and receiving unit 4 is in a horizontal state, it is used to receive the original laver sheet. When stamping and slitting are performed, the stamping unit 2 moves downward, acts on the original laver sheet, continues to move downward, drives the original laver sheet to move downward, and the flipping and receiving unit 4 is forced to flip downward, so that the original laver sheet contacts the slitting unit 3. Under the combined action of the stamping unit 2 and the slitting unit 3, the original laver sheet is slit into nine laver blocks.

[0046] As a preferred implementation manner of this embodiment, the bottom area of the stamping block 8 is adapted to the cross-sectional area of the slitting area 9 of the slitting unit 3, and is the same as the area of the slit laver block. The bottom area of the middle stamping block 8 is the same as the cross-sectional area of the slitting area 9 and is the same as the area of the slit laver block. The bottom areas of the eight stamping blocks 8 around are greater than or equal to the area of the slit laver block. When the stamping blocks are gathered, the total bottom area of the nine stamping blocks should be greater than or equal to the area of the original laver sheet. This can avoid damage to the original laver sheet. The original laver sheet contacted by the bottom of the stamping block 8 is not stressed. Therefore, when stamping, the laver blocks can be completely retained.

[0047] If the bottom area of the stamping block 8 is different from the area of the slit material block (mainly less than the area of the material block), it is impossible to ensure the flatness of the edges of each slit laver block. If there is a gap between the bottom of the stamping block 8 and the slitting knife 5 of the slitting unit 3, the original laver sheet may break at any position within this gap, resulting in unevenness of the slit laver blocks. Therefore, the preferred solution of this embodiment is that the bottom area of the stamping block 8 is the same as the cross-sectional area of the slitting area 9 of the slitting unit 3 and is also the same as the area of the slit laver block to ensure the flatness of the slit laver blocks.

[0048] As an implementation manner of this embodiment, when using the slitting units 3 distributed in a "well" shape and the nine stamping blocks 8 distributed in a nine-square grid to stamp and slit seaweed, nine seaweed blocks can be slit at one time, and the slitting can be completed at once. For relatively thick seaweed, after stacking can be completed in advance, and then placed on the flipping and receiving unit 4, or the stacking of multiple pieces of seaweed can be completed on the flipping and receiving unit 4, and then the stamping unit 2 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 is applicable to relatively thick seaweed, and multiple pieces of seaweed 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 seaweed.

[0049] Refer to the attached drawings of the specification Figure 4 and the attached Figure 5 As shown, the outer side surface of the slitting knife 5 is set as an inclined surface 7. When the stamping block 8 performs stamping and cutting, it will spread outwards along the inclined surface 7 of the outer side surface of the slitting knife, increasing the distance between the slit seaweed blocks. This is beneficial for the loading and supporting of the seaweed blocks. Nine trays 30 can be directly placed under the slitting unit 3. The slope of the outer side surface of the slitting knife 5 is the distance between adjacent trays 30. In this way, the seaweed blocks obtained by stamping and slitting can directly fall into the trays 30, completing the slitting and loading and supporting of the original seaweed sheet, and the efficiency can be greatly improved.

[0050] Embodiment 2

[0051] As another preferred embodiment of the present utility model, this embodiment is a further detailed supplement and elaboration of the technical solution of the present utility model on the basis of the above-mentioned Embodiment 1. In this embodiment, the nine stamping blocks 8 of the stamping unit 2 can be driven by separate power, that is, nine stamping driving units 1 are required. The nine stamping driving units 1 can be assembled according to the movement trajectories of the stamping blocks 8 they are respectively connected to, and making the nine stamping driving units 1 operate in unison can be achieved. However, this structure has a relatively high cost.

[0052] Therefore, considering the cost, this embodiment provides a preferred technical solution. Refer to the attached drawings of the specification Figure 1 and the attached Figure 2As shown, the stamping unit 2 further includes a stamping plate 10 and nine connecting rods 11. The nine connecting rods 11 are respectively connected to the nine stamping blocks 8. The upper ends of the nine connecting rods 11 are all connected to the stamping plate 10. The upper and lower ends of the eight connecting rods 11 located on the outside are respectively connected to the stamping plate 10 and the stamping block 8 through universal joint bearings 12. The stamping plate 10 and the connecting rods 11 drive the nine stamping blocks 8 to move synchronously. The stamping block 8 located in the middle moves vertically, and while the eight stamping blocks 8 located on the outside are moving vertically, they also need to expand outwards (i.e., move outwards along the outer inclined surface 7 of the cutting knife 5), so that the cut seaweed blocks can be dispersed and fall into the tray 30 below the cutting unit 3 respectively, and the two processes of cutting and loading can be completed.

[0053] Further preferably, a connecting disc 13 is provided on the connecting rod 11 located in the middle, and a tension spring is provided between the connecting rod 11 located on the outside and the connecting disc 13. This is beneficial to the automatic aggregation when the stamping block 8 moves upwards, that is, when the stamping block 8 leaves the cutting unit 3, under the action of the tension spring, the outer stamping blocks 8 gather around the stamping block 8 in the middle for the next stamping.

[0054] Further preferably, referring to the attached Figure 1 and attached Figure 2 As shown, the stamping driving unit 1 includes a stamping support frame 14 and a stamping driving member 15 installed above the stamping support frame 14. A stamping guide shaft 16 is provided on the stamping support frame 14, and the stamping plate 10 is slidably assembled on the stamping guide shaft 16; the stamping driving member 15 is connected to the stamping plate 10 to drive the stamping plate 10 to perform a linear reciprocating motion along the stamping guide shaft 16. The stamping driving member 15 provides power for the stamping plate 10. The stamping support frame 14 supports the stamping driving member 15 on the one hand and also provides guiding support for the stamping plate 10 on the other hand, so that the stamping unit 2 can operate more stably.

[0055] Embodiment 3

[0056] As another preferred embodiment of the present invention, this embodiment is a further detailed elaboration and supplement of the technical solution of the present invention on the basis of the above Embodiment 1 or Embodiment 2. In this embodiment, referring to the attached Figure 6 As shown, the flipping and receiving unit 4 includes four flipping shafts 17 arranged around the cutting unit 3. The four flipping shafts 17 are all supported around the cutting unit 3 by a support member 20. The flipping shafts 17 rotate relative to the support member 20, and a plurality of receiving and flipping plates 18 extending horizontally towards the cutting area 9 of the cutting unit 3 are provided on the flipping shafts 17; a return spring 19 is also provided on the flipping shafts 17 to ensure that the flipping shafts 17 and the receiving and flipping plates 18 return to their original positions after the stamping unit 2 leaves the cutting unit 3. The cutting knife 5 of the cutting unit 3 is fixed by the support member 20.

[0057] The structure of the flipping and material receiving unit 4 is simple and can be automatically reset. Its main function is to temporarily receive the original laver sheet when slitting is not carried out. It can receive the stacked original laver sheets and can also stack the original laver sheets.

[0058] Embodiment 4

[0059] As another preferred embodiment of the present utility model, this embodiment is a further detailed supplement and elaboration of the technical solution of the present utility model on the basis of the above-mentioned Embodiment 1, Embodiment 2 or Embodiment 3.

[0060] The chamber walls 22 of the stamping chamber 21 are fixed by pins and can be disassembled for easy observation.

[0061] The setting of the stamping chamber 21 can ensure the sealing performance above the slitting unit 3. On the one hand, it ensures the hygiene of the original laver sheet and avoids the pollution of the original laver sheet by the outside world. On the other hand, it also ensures that the dust generated when the stamping unit 2 stamps the original laver sheet does not escape to the outside and pollutes the equipment components.

[0062] Embodiment 5

[0063] As another preferred embodiment of the present utility model, this embodiment is a further detailed supplement and elaboration of the technical solution of the present utility model on the basis of 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 、the attached Figure 3 as well as the attached drawings of the specification Figure 6 、the attached Figure 7 、the attached Figure 8 and the attached Figure 9 As shown, a material receiving unit 25 is provided on one side of the slitting unit 3. The material receiving unit 25 includes a material receiving plate 26 and a material receiving driving assembly 27. The material receiving driving assembly 27 drives the material receiving plate 26 to perform a linear reciprocating motion. When the material receiving plate 26 extends, it is located above the flipping and material receiving unit 4. When the material receiving plate 26 retracts, the material receiving plate 26 leaves above the flipping and material receiving unit 4 and is located on one side above the flipping and material receiving unit 4.

[0064] Further preferably, for the convenience of material receiving and layout, the material receiving unit 25 is located on the opposite side of the stamping chamber 21 where the chamber door 23 is provided.

[0065] 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 25 is withdrawn, the nori sheet can fall onto the flip receiving unit 4. After the receiving unit 25 is added, the nori sheet can be stacked on the flip receiving unit 4. 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 30, realizing automatic receiving and stacking, thereby improving the slitting efficiency and tray loading efficiency.

[0066] Furthermore, the slitting unit 3 is mounted on the slitting support frame 28, and a tray conveying channel 31 is formed between the legs 29 of the slitting support frame 28. The material blocks punched and cut by the punching unit 2 fall into the tray 30 in the tray conveying channel 31. The tray 30 can be conveyed from the tray conveying channel 31 to the bottom of the slitting unit 3. Figure 10 As shown, the trays 30 in the tray conveying channel 31 are arranged to correspond to the slitting areas 9 in the slitting unit 3, and the seaweed blocks obtained after slitting can be received, and automatic material receiving, stacking and loading can be realized, thereby improving the slitting and loading efficiency.
