[0002] Laver processing is divided into primary processing and deep processing, among which, the primary processing of laver refers to the process of processing the harvested fresh laver raw materials into dry laver products, and the forms of dry laver products are mostly laver sheets and laver cakes; the deep processing of laver refers to heating the above-mentioned laver sheets or laver cakes (with or without adding seasonings) to obtain laver (also called "seaweed") that can be eaten after being baked. In the process of deep processing of the above-mentioned laver sheets, in order to meet the automation work, it is necessary to use an automatic laver sheet supply device. Most of the existing laver sheet supply devices use the principle of negative pressure adsorption to separate and supply laver sheets, including negative pressure adsorption mechanism, dynamic isolation mechanism, sheet output mechanism, etc., and there is a linkage mechanism between each mechanism, which has a complex structure and poor working reliability. In addition, the existing devices are all horizontal output of laver sheets, which is not well applicable to some specific occasions of laver deep processing. Therefore, it is very necessary and important to develop a supply device with a simpler structure, more reliable operation, and vertical release of laver sheets to make up for the shortcomings of the existing technology. Summary of the invention

The fixed material rack assembly and the movable material rack assembly together define a "material chamber" for holding laver sheet raw materials, and the air head assembly is arranged directly below the "material chamber"; the air head assembly that moves up and down adsorbs, covers and extracts the laver sheets in the "material chamber" above it with the assistance of the air distribution assembly. After the air head assembly is flipped, the adsorbed laver sheets are released, thereby completing the supply operation of the laver sheets.

[0005] As an improvement of the present invention, the frame assembly includes a left frame and a right frame, the movable material rack assembly is installed on the left frame and can be moved up and down by a guide device, the movable material rack assembly is driven to move up and down by a driving assembly, the driving assembly is installed on the left frame, and the air distribution assembly is fixedly installed on the right frame; the air head assembly is rotatably installed between the left frame and the air distribution assembly; the fixed material rack is fixedly installed on the right frame by a connecting piece, and its left and right, front and back position is adjustable.

[0006] As an improvement of the present invention, the movable rack assembly includes a movable rack body, which is composed of a movable rack vertical part and a movable rack horizontal part, and is generally in an "L" shape, and is arranged in pairs. The purpose of the paired arrangement is to form a gap between the two movable rack bodies to facilitate the material discharge operation. At the same time, compared with the integral structure, the weight can be reduced and the inertial impact force of its up and down movement can be reduced;

[0007] The fixed material rack includes a fixed material rack body and a connecting piece; the above-mentioned movable material rack body and the fixed material rack body together constitute a "material chamber" that can hold a family of laver sheets, wherein the vertical part of the movable material rack body and the fixed material rack body limit the family of laver sheets in the horizontal direction, and the horizontal part of the movable material rack body limits the family of laver sheets in the vertical direction; the fixed frame body is installed on the right frame through the connecting piece, and the relative positions between the paired fixed frame bodies and relative to the movable material rack body are adjustable to accommodate laver sheets of different sizes.

[0008] As an improvement of the present invention, the movable material rack assembly also includes a guide sleeve and a guide rod, wherein the guide sleeve is fixedly mounted on the movable material rack body, and the guide rod is fixedly mounted on the left side frame, so that the movable frame body is limited to only move in the up and down directions; the movable material rack body is also provided with a connecting piece, and the connecting piece is provided with an axis head structural feature for connecting a driving piece to drive the movable material rack body to perform up and down reciprocating motion.

The other end of the eccentric rocker arm is provided with a shaft head, which is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the shaft head on the connecting piece. In this way, when the output shaft of the power device rotates, it will drive the eccentric rocker arm to rotate, and then drive the movable material rack body to reciprocate up and down through the connecting rod connecting piece.

[0010] As an improvement of the present invention, the air head assembly includes an air head body, a channel tube, a rotating shaft and a power device, wherein the air head body is arranged as a hollow structure, and its cross section is a closed curved surface structure. A through hole that connects its internal cavity with the outside is arranged in a specific area on the circumferential wall of the body. The air source can flow through the hollow structure and these through holes to adsorb the laver sheets when they are covered and release the laver sheets when the air pressure direction is changed. The channel tube is also a hollow structure, and its cross section is a circular ring. It is arranged at one end of the air head body and its internal hollow is connected to the internal cavity of the air head body. The channel tube leads to the air distribution assembly to convert the air pressure direction of the internal cavity of the air head body. The other end of the air head body is closed and connected to the rotating shaft. The center of the rotating shaft is concentric with the rotation center of the air head body. The rotating shaft extends out of the left frame and is concentrically connected to the output shaft of the power device. The power device is arranged as a pneumatic motor, or a reduction motor or other device with rotational power output, which is used to drive the air head body to perform horizontal rotation or deflection movement.

[0011] The gas distribution assembly includes a gas distribution chamber, the cross section of which is a polygonal ring body with a hollow structure. A through hole is provided on one wall of the ring body, which passes through its inner cavity and the external space. The channel pipe on the gas head assembly extends into the through hole and is a sliding fit. On the one hand, it plays a role in supporting the gas head body, and on the other hand, it makes the internal cavity of the gas head body and the internal cavity of the gas distribution chamber interpenetrate. In this way, under the rotational power of the output shaft of the power device, the gas head body is driven by the rotating shaft to deflect or rotate.

[0012] As an improvement of the present invention, the air distribution assembly also includes an air intake port, an air supply port, an air intake valve plate, an air supply valve plate, an air intake power member and an air supply power member, wherein the air intake port and the air supply port both have a hollow structure, and their cross-sections are curved or polygonal rings, which are respectively arranged at both ends of the air distribution chamber, and their internal cavities are connected with the internal cavity of the air distribution chamber.

[0013] As an improvement of the present invention, the air intake port on the air distribution component is connected to a negative pressure wind (gas) source (not shown in the figure). When the air supply valve plate blocks the air supply port and the air intake valve plate opens the air supply port, the wind suction force of the negative pressure wind source will be applied to the through hole through the air intake port, the air distribution chamber channel pipe, and the air head body in sequence. That is to say, negative pressure wind suction force will be generated at the through hole. At this time, if the air head body is in contact with the seaweed sheet family, the wind suction force at the through hole will adsorb and adhere the seaweed sheets close to it to the outer surface of the air head body; then, when the air intake valve plate blocks the air intake port and the air supply valve plate opens the air supply port by air intake, the internal cavity of the air head body will lose the negative pressure suction force. At this time, the seaweed sheets previously adsorbed on the outer surface of the air head body will no longer be adsorbed. If the seaweed sheets are in a downward position, the seaweed sheets will fall off the air head body by their own weight.

[0014] Compared with the prior art, the technical effects of the present invention are as follows: 1) The technical solution does not require a dynamic isolation device or a sheet output device, which simplifies the linkage mechanism, making the overall structure simpler, compact and ingenious, and realizing the rapid and continuous supply of laver sheets, and the operation is stable and reliable; 2) The technical solution adopts a rotary air head design to realize the vertical release of laver sheets, which is particularly suitable for the covering process of the sandwich seaweed unit, and has the technical advantages of accurate and neat covering and no need for manual intervention; 3) The technical solution is more suitable for a double-station design. In the double-station working mode, the above advantages are more prominent. BRIEF DESCRIPTION OF THE DRAWINGS

The channel pipe leads to the air distribution assembly to convert the air pressure direction of the internal cavity of the air head body. The other end of the air head body 101 is closed and connected to the rotating shaft 103. The center of the rotating shaft 103 is concentric with the rotation center of the air head body 101. The rotating shaft 103 extends out of the left frame 601 and is concentrically connected to the output shaft of the power device 104. The power device 104 is configured as a pneumatic motor, or a reduction motor or other device with rotational power output; it is used to drive the air head body to perform horizontal rotation or deflection movement.

[0027] The gas distribution assembly 5 includes a gas distribution chamber 501, the cross section of which is a polygonal ring body with a hollow structure, and a through hole is provided on one wall of the ring body to connect the inner cavity thereof with the external space, and the channel tube 102 on the gas head assembly 1 extends into the through hole and is a sliding fit, which, on the one hand, plays a role in supporting the gas head body 101, and on the other hand, enables the internal cavity 10102 of the gas head body 101 to be connected with the internal cavity of the gas distribution chamber 501. In this way, driven by the rotational power of the output shaft of the power device 104, the gas head body 101 is driven to deflect or rotate via the rotating shaft 103.

[0028] The air distribution assembly 5 also includes an air intake port 502, an air supply port 502′, an air intake valve plate 503, an air supply valve plate 503′, an air intake power part 504, and an air supply power part 504′, wherein the air intake port 502 and the air supply port 502′ both have a hollow structure, and their cross-sections are curved or polygonal rings, which are respectively arranged at both ends of the air distribution chamber 501, and their internal cavities are connected with the internal cavity of the air distribution chamber 501.

At this time, if the air head body 101 is in contact with the seaweed sheet family, the through hole 10101 The wind suction at 101 will absorb the laver sheets near it and stick them to the outer surface of the air head main body 101; then, when the air intake valve plate 503 blocks the air intake port 502 and the air supply valve plate 503 takes in air to open the air supply port 502', the internal cavity 10102 of the air head main body 101 will lose the negative pressure suction.

[0030] Working process: According to the following Figure 1 — Figure 3 and Figure 4 — Figure 8 The working principle and working process of the rotary air head type laver sheet supply device of the present invention are described in detail:

[0031] First of all, it should be noted that in order to make the diagram simpler and easier to describe and understand, Figure 4 — Figure 8 Only some core components of the device of the present invention are shown, and they correspond to different working states of the device respectively.

[0032] like Figure 4 The state shown is defined as the initial state, in which the movable rack bodies 201 and 201′ of the device of the present invention are at the highest position, and at the same time, the distribution area of ​​the through holes 10101 on the gas head body 101 is upward, and at this time, the gas head body 101 and the seaweed sheet family 7 are non-contacting; in the initial state, Figure 1 The air supply valve plate 503 ′ is in a state of blocking the air supply port 502 ′, and the air intake valve plate 503 is in a state of opening the air intake port 502 .

[0033] exist Figure 4 Based on the initial state, Figure 1 The middle driving assembly 4 is actuated to drive the movable rack bodies 201 and 201' downwards through the eccentric rocker arm 402, the connecting rod 403 and the connecting piece 204 until they reach the position as shown in FIG. Figure 5The lowest position shown in the figure, at this time, the upper surface of the air head body 101 is in contact with the last sheet 701 of the seaweed sheet family 7, and the negative pressure wind suction at the through hole 10101 of the air head body 101 will act on the last seaweed sheet 701 and adsorb and cover the seaweed sheet 701 on the upper surface of the air head body 101.

[0034] exist Figure 5 Based on the status shown, Figure 1 The middle drive assembly 4 moves again, and drives the movable rack bodies 201 and 201' to move upward through the eccentric rocker arm 402, the connecting rod 403, and the connecting piece 204 until they reach the position shown in FIG. Figure 6 In the process, the movable rack bodies 201 and 201' lift the laver sheet family 7 and move upward and separate from the air head body 101 that has absorbed the last laver sheet 701. The laver sheet 701 absorbed on the air head body 101 has a curled size smaller than the distance between the movable rack bodies 201 and 201'. Therefore, in the process of the movable rack bodies 201 and 201' being lifted, the absorbed laver sheet 701 will always be absorbed on the air head body 101 without being interfered with or damaged by the movable rack bodies 201 and 201'.

[0035] exist Figure 6 Based on the status shown, Figure 1 The power device 104 is activated to drive the air head body 101 to rotate 180 degrees through the rotating shaft 103, so that the last laver sheet 701 adsorbed is in a position as shown in FIG. Figure 7 In this process, since the inner cavity of the air head main body 101 always maintains negative pressure wind suction, the laver sheet will not be separated from and fall off the air head main body 101.

[0036] exist Figure 7 Based on the status shown, Figure 1 The air suction power member 504 in the air head body 101 is actuated to drive the air suction valve plate 503 to block the air suction port 502. At the same time, the air supply power member 504' is actuated to drive the air supply valve plate 503' to open the air supply port 502', so that the negative pressure wind suction force in the inner cavity of the air head body 101 disappears. Figure 8 As shown, at this time, the laver sheet 701 will be separated from the air head body 101 and fall down under the action of its own weight, thus completing the complete separation operation of a laver sheet.

[0037] By repeating the above working process, the last laver sheet in the laver sheet family 7 will be sucked and separated by the air head body 101 in turn, thereby realizing the continuous separation and vertical supply of the laver sheets.

[0038] During the above working process, the working sequence and position relationship of each mechanism are controlled by sensors and program settings.

[0039] It should be noted that the above embodiments are not intended to limit the protection scope of the present invention, and equivalent changes or substitutions made on the basis of the above technical solutions all fall within the protection scope of the claims of the present invention.
