Description

Technical Field

[0001] The present invention relates to the field of laver packaging equipment, in particular to a laver packaging machine and a working method. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Laver is a kind of plant rich in many nutrients. Its leaves are the edible parts and can be made into cake vegetables, roasted laver, loose vegetables, dried vegetable cakes, etc. In the prior art, the production equipment related to laver is mainly the drying equipment of laver. Regarding its packaging equipment, there is a scheme of packaging laver by providing vacuum bags, but this packaging method has not been recognized by the market. At present, many lavers on the market are packaged with wrapping paper and then labeled, which is a common packaging method. For this packaging method, most of the prior art is completed manually. Manual packaging naturally has hygiene problems and low packaging efficiency.

[0004] Although there are also some schemes that propose laver packaging equipment, specifically using a heat shrink packaging machine for laver packaging. During the working process of the heat shrink packaging machine, the shape of the wrapping paper is changed by heating. Since some wrapping papers are plastic, it is obvious that the harmful components of the wrapping paper are released by the heating method, which is not conducive to food health.

[0005] Moreover, the existing packaging machines mainly still manually put laver into the wrapping paper and gather it on a simple workbench. In this process, food safety problems are also affected, and then heat shrinkage is carried out by the machine. The degree of automation is low and the working efficiency is also low. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a laver packaging machine that can achieve rapid packaging of laver.

[0007] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0008] A laver packaging machine includes a frame. The frame supports a first cylinder and a second cylinder. The first cylinder is hollow. A second cylinder is arranged above the first cylinder. A space for accommodating the wrapping paper is formed by setting a distance between the first cylinder and the second cylinder. Laver sheets fall into the wrapping paper through the upper part of the second cylinder. A first conveying mechanism is arranged below the first cylinder. The first conveying mechanism is provided with a hollow structure. An air suction mechanism is arranged below the first conveying mechanism. The air suction mechanism is located below the first cylinder. The air suction mechanism works to adsorb the wrapping paper. The wrapping paper with laver sheets passes through the first cylinder and falls at the first conveying mechanism. A gathering mechanism is located at the side of the first conveying mechanism to gather the wrapping paper.

[0009] In the laver packaging machine as described above, a pressing mechanism is arranged above the second cylinder, and the pressing mechanism can be raised and lowered to press the laver sheets downward so that the packaging paper containing the laver sheets enters the first cylinder. Considering that the packaging paper needs to move forward with the corresponding conveying mechanism after being cut, and there is a connection between the packaging paper and the packaging base paper, the setting of the pressing mechanism is also conducive to the packaging paper being separated from the packaging base paper, and is conducive to the packaging paper reaching the first conveying mechanism under the action of the suction mechanism.

[0010] In the laver packaging machine as described above, the first conveying mechanism includes a first conveyor belt, a plurality of fixed frames are installed on the surface of the first conveyor belt, the fixed frames are rotatable relative to the first conveying mechanism, the fixed frames are hollowed out so that the packaging paper can be adsorbed on the fixed frames by the suction mechanism, the fixed frames can drive the packaging paper to move with the movement of the first conveyor belt, the fixed frames can rotate so that during the rotation of the packaging paper driven by the fixed frames, the packaging paper can be gathered by the gathering mechanism to wrap the laver sheets.

[0011] In the laver packaging machine as described above, the fixed frame is arranged at a distance from the bottom side of the first cylinder, and the fixed frame has a bending portion on the side away from the first conveyor belt, the bending portion is bent toward the center direction of the fixed frame, and the bending portion is arranged lower than the folding mechanism. Through the arrangement of the bending portion, the packaging paper will not fall off during the movement of the fixed frame.

[0012] In the laver packaging machine as described above, the gathering mechanism includes gathering frames located on both sides of the first conveying mechanism, the gathering frames are supported by the frame, and the gathering frames on both sides are set at a distance. One side of the gathering frame is located above the first conveying mechanism. Along the forward direction of the first conveying mechanism, the distance between the gathering frames on both sides gradually decreases to ensure the gathering effect of the packaging paper.

[0013] The laver packaging machine as described above, in order to further realize automated operation, further comprises a second conveying mechanism supported by the frame, wherein the outlet end of the second conveying mechanism is arranged higher than the second cylinder, and the second conveying mechanism is used to convey the laver sheets;

[0014] The inner width of the second cylinder on one side facing the second conveying mechanism is gradually increased, so as to facilitate the laver sheets to gradually fall into the packaging paper and ensure the final state of the laver sheets after falling into the packaging paper.

[0015] The laver packaging machine as described above, in order to realize the automatic transmission of packaging paper, also includes a third transmission mechanism supported by a frame, the third transmission mechanism is located between the first cylinder and the second cylinder, the third transmission mechanism includes a third conveyor belt, the middle part of the third conveyor belt is hollow, and the third transmission mechanism is used to transmit the packaging paper.

[0016] A laver packaging machine as described above, a packaging base paper roll is arranged on one side of the third conveying mechanism away from the first conveying mechanism, and a shearing mechanism is arranged above the third conveying mechanism. The shearing mechanism cuts out the packaging paper from the packaging base paper roll. The shearing mechanism includes a circular cutter, and a notch is arranged on the cutting edge surface of the circular cutter. The circular cutter is connected to a lifting component. The notch arranged on the shearing mechanism enables a connection between the preliminarily cut packaging paper and the packaging base paper, which is beneficial for the cut packaging paper and the packaging base paper to continue moving forward together.

[0017] A laver packaging machine as described above further includes a labeling mechanism. The labeling mechanism is arranged on the upper side or the lower side of the first conveying mechanism. After the packaging paper is folded, the labeling mechanism labels the packaging paper.

[0018] The labeling mechanism includes a label paper roll wound by a label paper with an adhesive. The label paper with an adhesive is drawn out from the label paper roll and wound around a rotating roll after being guided by a plurality of guide rolls. One of the guide rolls is a reversing roll, and a linear driving mechanism is arranged on one side of the reversing roll. After the label paper with an adhesive passes through the reversing roll, the label paper is separated from the adhesive.

[0019] Secondly, the present invention also provides a working method of a laver packaging machine, including the following contents:

[0020] The packaging paper enters between the first cylinder and the second cylinder.

[0021] Laver slices fall onto the packaging paper from above the second cylinder.

[0022] The air suction mechanism works to adsorb the packaging paper, and the packaging paper with the laver slices falls onto the first conveying mechanism after passing through the first cylinder.

[0023] The packaging paper containing laver slices advances as the first conveying mechanism advances, and the folding mechanism folds the packaging paper during the advancing process.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) The laver packaging machine provided in the present invention forms a space for packaging paper between the first cylinder and the second cylinder. The packaging paper is placed on the bottom side of the second cylinder, and laver slices fall into the packaging paper. When the air suction mechanism works, since both the packaging paper and the laver slices are light, under the suction effect, the packaging paper containing laver slices falls along the first cylinder to the first conveying mechanism. A folding mechanism is arranged on the side of the first conveying mechanism, and the packaging paper can be folded through the folding mechanism to achieve the preliminary packaging of the laver slices. The first conveying mechanism and the first cylinder cooperate to receive the packaging paper, effectively replacing the existing simple workbench. The structure is reasonably arranged. In this process, there is no need to contact the operators, and the folding mechanism works without manual folding, fully ensuring food safety and effectively improving the working efficiency of laver packaging.

[0026] 2) In the present invention, considering that there is a connection between the packaging paper after being cut and the original packaging paper, a pressing mechanism is arranged above the second cylinder. The pressing mechanism can be lifted and lowered to press the laver slices and the packaging paper downward, and cooperate with the air suction mechanism to make the packaging paper containing laver slices fall to the fixing frame of the first conveying mechanism.

[0027] 3) The fixing frame at the first conveying mechanism of the present invention can rotate. When the fixing frame rotates to drive the packaging paper to rotate, the folding mechanism can fold the entire circle of the packaging paper to wrap the laver slices. There is a bending part on the side of the fixing frame away from the first conveyor belt. Through the setting of the bending part, when the packaging paper moves with the fixing frame, it will not fall off. The structure of the bending part is reasonably arranged, and it is also beneficial for the packaged laver to fall off from the fixing frame under the action of external force.

[0028] 4) The folding mechanism of the present invention has a reasonable structure. The folding mechanism includes two relatively arranged folding frames. Along the advancing direction of the first conveying mechanism, the distance between the two side folding frames gradually decreases, so as to effectively fold the entire circle of the packaging paper during the advancement and rotation of the fixing frame.

[0029] 5) The present invention realizes the automatic packaging of laver, can cut the packaging paper, transport the laver slices, and fold the packaging paper after containing laver slices. Finally, it can also apply labels to realize the automated operation of laver packaging, effectively replacing manual labor and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations;

[0039] As introduced in the background art, the automatic packaging of laver in the prior art has not been recognized by the market, and there are problems with food safety and food hygiene in the traditional packaging method. To solve the above technical problems, the present invention proposes a laver packaging machine.

[0040] Embodiment 1

[0041] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a laver packaging machine includes a frame, which supports a first cylinder 6 and a second cylinder 5. The first cylinder 6 is hollow, and the second cylinder 5 is arranged above the first cylinder. The first cylinder 6 and the second cylinder 5 are spaced apart to form a space for accommodating packaging paper. The diameter of the packaging paper 14 is greater than the outer diameters of the first cylinder 6 and the second cylinder 5. The height of the first cylinder 6 is higher than that of the second cylinder 5. The laver sheet 10 passes through the second cylinder 5 and falls into the packaging paper 14. The diameter of the laver sheet 10 is smaller than the inner diameter of the first cylinder 6. A first conveying mechanism 16 is arranged below the first cylinder 6. The first conveying mechanism 16 is hollow, and a suction mechanism 15 is arranged below the first conveying mechanism 16. The suction mechanism 15 is located below the first cylinder 6. The suction mechanism 15 works to absorb the packaging paper 14. The packaging paper 14 carries the laver sheet through the first cylinder 6 and falls at the first conveying mechanism 16. The gathering mechanism is located on the side of the first conveying mechanism to gather the packaging paper 14.

[0042] Specifically, the first conveying mechanism 16 includes a first conveying belt 20, and the first conveying mechanism 16 is also supported by a frame. The first conveying belt 20 is arranged to bypass a first active roller and a first driven roller, and the first active roller is connected to a power source.

[0043] To further realize automated operation, the packaging machine further includes a second conveying mechanism 11 supported by a frame, wherein an outlet end of the second conveying mechanism 11 is arranged higher than the second cylinder 5, and the second conveying mechanism 11 is used to convey the laver sheet 10;

[0044] Specifically, the second conveying mechanism 11 includes a second conveyor belt 12, which is arranged to bypass a second active roller 13 and a second driven roller. The moving direction of the second conveyor belt 12 is opposite to the moving direction of the first conveyor belt 20. The second conveyor belt 12 moves toward the second cylinder, and the first conveyor belt moves in a direction away from the second cylinder.

[0045] It should be noted that, considering that the second cylinder 5 is arranged close to the second active roller 13, the second active roller is arc-shaped, and considering that the laver sheet 10 gradually falls downward from the top of the arc, the internal width of the second cylinder 5 on the side facing the second conveying mechanism gradually increases, and the longitudinal cross-section of the second cylinder is an inverted trapezoidal structure, that is, the second cylinder 5 is provided with an inclined side on the side facing the second conveying mechanism 11, so as to facilitate the laver sheet 10 to gradually fall into the wrapping paper 14, and fall into the second cylinder 5 through the inclined side of the second cylinder 5, thereby ensuring that the final state of the laver sheet after falling into the wrapping paper is parallel to the wrapping paper, so that the laver sheet is flat on the wrapping paper.

[0046] It should be noted that the laver sheet 10 refers to one or two or more laver sheets. Multiple laver sheets can fall at the second cylinder at the same time, or only one laver sheet can fall at a time. The laver sheet is a circular laver sheet, and the wrapping paper for wrapping the laver sheet is also circular. The laver sheet falls at the middle position of the wrapping paper.

[0047] To achieve the automatic transmission of the wrapping paper, it further includes a third transmission mechanism 4 supported by a frame. The third transmission mechanism includes a third conveyor belt that bypasses the third driving roller 19 and the third driven roller. The third transmission mechanism 4 is located between the first cylinder 6 and the second cylinder 5. The third transmission mechanism 4 is provided with a hollow structure and is used for transmitting the wrapping paper 14. The third driving roller 19 is located on one side of the second driving roller 13. The third conveyor belt includes two conveyor belts, and the two conveyor belts are arranged at an interval so that the third conveyor belt is hollowed out up and down. The distance between the two conveyor belts is smaller than the width of the original wrapping paper. The cut wrapping paper advances together with the original wrapping paper. The hollowed-out third conveyor belt facilitates the wrapping paper to fall into the first cylinder 6 under the action of the air suction mechanism 15. The inner diameter of the circular notch is larger than the diameter of the laver sheet.

[0048] It is easily understood that a roll of original wrapping paper 2 is arranged on the side of the third transmission mechanism 4 away from the first transmission mechanism 16. The roll of original wrapping paper 2 is wound by a rectangular original wrapping paper. The roll of original wrapping paper 2 is wound around a paper tube. After the paper tube is sleeved on the support roller 1, one end of the original wrapping paper bypasses the third driving roller 19. Under the transmission action of the third transmission mechanism 4, the roll of original wrapping paper 2 rotates relative to the support roller 1, and the third transmission mechanism 4 gradually conveys the original wrapping paper to the lower part of the second cylinder 5;

[0049] It is easily understood that a cutting mechanism 3 is arranged above the third transmission mechanism 4. The cutting mechanism 3 cuts out the wrapping paper 14 from the roll of original wrapping paper. Refer to Figure 3 As shown, the cutting mechanism 3 includes a circular cutter 23. A notch 24 is arranged on the cutting edge surface of the circular cutter 23. The circular cutter 23 is connected to a lifting component. The lifting component can be a lifting electric cylinder. The lifting electric cylinder is connected to the circular cutter, and the fixed end of the lifting component is installed on the frame; a support plate is installed through the frame. The support plate is arranged below the upper side of the third conveyor belt. The cutting mechanism 3 is located above the support plate. The support plate plays a supporting role during the working process of the cutting mechanism, and the support plate will not enter the lower part of the second cylinder.

[0050] Specifically, the inner diameter of the circular cutter 23 is smaller than the outer diameter of the circular notch 24 at the third conveyor belt to ensure the initial cutting of the wrapping paper. The shearing mechanism 3 is provided with the notch 24 so that the wrapping paper after the initial cutting is connected with the packaging base paper, which is conducive to the wrapping paper after cutting to continue to move forward together with the packaging base paper. When the circular notch of the third conveyor belt falls below the second cylinder 5, the pressing mechanism located above the second cylinder is actuated to press the laver sheet 10 and the wrapping paper 14 downward, so that the wrapping paper 14 and the laver sheet 10 fall from the circular notch.

[0051] Specifically, the pressing mechanism 7 can be raised and lowered to press the laver sheet 10 downward, and the pressing mechanism includes a connecting rod, which is connected to a pressing plate 8. A flexible member such as a sponge 9 is fixed to the side of the pressing plate 8 away from the connecting rod, and the connecting rod is connected to a linear drive component such as a linear drive electric cylinder. The setting of the pressing mechanism allows the wrapping paper 14 containing the laver sheet to enter the first cylinder 6. Considering that the wrapping paper 14 needs to move forward with the corresponding conveying mechanism after being cut, and there is a connection between the wrapping paper 14 and the packaging base paper, the setting of the pressing mechanism is also conducive to the wrapping paper 14 to separate from the packaging base paper, and to facilitate the wrapping paper 14 to reach the first conveying mechanism under the action of the suction mechanism 15.

[0052] It is easy to understand that the pressing mechanism 7, the suction mechanism 15, the cutting mechanism 3, the first conveying mechanism 16, the second conveying mechanism 11 and the third conveying mechanism 4 are all connected to the controller. The controller can be a PLC controller or other types of controllers. The controller controls the actions of each mechanism to realize the automated operation of seaweed packaging.

[0053] refer to Figure 2 As shown, a plurality of fixing frames 18 are installed on the surface of the first conveyor belt 20, and the fixing frames 18 are rotatable relative to the first conveying mechanism 16. A rotating motor is supported at the first conveyor belt, and the rotating motor is connected to the controller, and the rotating motor is connected to the fixing frames 18. The fixing frames 18 are hollowed out to adsorb the wrapping paper to the fixing frames 18 through the suction mechanism 15. The fixing frames 18 can drive the wrapping paper 14 to move with the movement of the first conveyor belt 20. The fixing frames 18 can rotate to drive the wrapping paper to rotate through the fixing frames, and the wrapping paper can be gathered through the gathering mechanism to wrap the seaweed sheet 10.

[0054] It is easily understandable that a distance is set between the fixing frame 18 and the bottom side of the first cylinder body 6. The fixing frame can be a hollow disk, and the diameter of the disk is slightly larger than the diameter of the laver sheet 10. On the side of the fixing frame 18 away from the first conveyor belt 20, there is a bending part 21. The bending part 21 bends towards the center direction of the fixing frame. The bending parts can be placed on the opposite sides in the radial direction of the fixing frame. The bending part 21 can be L-shaped. One side of the bending part 21 is connected to the side of the fixing frame, and the other side of the bending part 21 is higher than the fixing frame. The bending part 21 is lower than the folding mechanism. Through the setting of the bending part, when the wrapping paper containing the laver sheet moves with the fixing frame 18, the situation of falling will not occur. The length of the bending part is less than half of the radius of the fixing frame 18, which is beneficial to make the wrapping paper enter the inner side of the bending part under the action of the air suction mechanism. The two oppositely arranged bending parts 21 are also beneficial to extract the finished product from the fixing frame after the labeling is completed.

[0055] It should be noted that the air suction mechanism 15 is fixed to the machine frame. The air suction mechanism selects an ordinary fan, as long as it can generate negative pressure. The suction port of the fan faces the first cylinder body 6.

[0056] In this embodiment, the folding mechanism includes folding frames located on both sides of the first conveying mechanism. The folding frames are supported by the machine frame. The folding frame 22 is located on the side of the first cylinder body. The folding frame 22 is located in the advancing direction of the first conveying mechanism. A distance is set between the two folding frames 22 on both sides. The longitudinal section of the folding frame 22 is L-shaped. One side of the folding frame is fixed to the machine frame, and the other side of the folding frame 22 is located above the first conveying mechanism 16 and covers part of the fixing frame. Along the advancing direction of the first conveying mechanism, the distance between the two folding frames on both sides gradually decreases to ensure the folding effect of the wrapping paper. The length of the folding frame can cover two adjacent fixing frames. The minimum distance between the folding frames is less than the diameter of the fixing frame. The wrapping paper containing the laver sheet 10 forms a semi-finished product after passing through the folding frame.

[0057] In some examples, the staff manually pastes a label (with adhesive) on the semi-finished product. To avoid interference, the diameter of the label paper is less than the distance between the two bending parts on both sides of the fixing frame.

[0058] In some examples, the packaging machine further includes a labeling mechanism 17. The labeling mechanism 17 is also connected to the controller. The labeling mechanism is arranged on the upper side of the first conveying mechanism. After the wrapping paper is folded, the labeling mechanism labels the wrapping paper.

[0059] In some examples, the labeling mechanism 17 includes a linear driving component. The linear driving component is a linear driving electric cylinder. A pressing plate is arranged at the telescopic end of the linear driving electric cylinder. The operator places the label paper above the semi-finished product, and the linear driving electric cylinder acts to paste the label paper on the semi-finished product to form a finished product.

[0060] In other examples, refer to Figure 4 As shown, in order to further realize automated operation and avoid manual operation, the labeling mechanism 17 includes a label paper roller 25, which is rotatable. The label paper roller is wound with continuous label paper with adhesive backing. After the label paper with adhesive backing is drawn out from the label paper roller 25, it passes through the first guide roller 26, the second guide roller 29, the third guide roller 30 and the fourth guide roller 31 and is wound to the rotating roller. The rotating roller 32 is rotatable by a motor. During the rotation of the rotating roller, the adhesive backing paper that drives the label paper away is gradually wound around the rotating roller 32.

[0061] Among them, the first guide roller 26 is arranged below the label paper roller 25, the second guide roller 29 is arranged beyond the first guide roller, the second guide roller 29 is a reversing roller, the second guide roller 29 is arranged slightly lower than the first guide roller 26, the third guide roller 30 is arranged lower than the second guide roller 29, the third guide roller 30 is located between the second guide roller 29 and the fourth guide roller 31, the fourth guide roller 31 is located between the third guide roller 30 and the rotating roller 32, the rotating roller is arranged below the label paper roller 25, and the label paper with adhesive backing changes from tilting downward to a horizontal state after passing through the first guide roller and the second guide roller, and then tilts downward through the third guide roller 30 and the fourth guide roller 31 to the rotating roller 32, and the label paper with adhesive backing undergoes a reversal of less than 45° at the second guide roller 29, and the label paper with adhesive backing changes direction when passing through the second guide roller, so that the label paper 28 can be separated from the adhesive backing, and the label paper gradually comes to the bottom of the linear drive mechanism 27 (which can be a linear drive electric cylinder), and the linear drive mechanism is activated, so that the label paper is pasted to the semi-finished product.

[0062] The packaging machine provided in this embodiment forms a space for packaging paper between the first cylinder 6 and the second cylinder 5, and the packaging paper 14 comes to the bottom side of the second cylinder through the third conveying mechanism, and the packaging paper 14 is arranged beyond the second cylinder and the first cylinder 6, and the laver sheet 10 falls into the packaging paper 14. When the suction mechanism 15 is working, because both the packaging paper 14 and the laver sheet 10 are relatively light, the packaging paper 14 containing the laver sheet 10 falls into the fixed frame 18 of the first conveying mechanism along the first cylinder 6 under the action of suction, and a gathering mechanism is arranged on the side of the first conveying mechanism. The wrapping paper containing the laver sheets can also be rotated as the first conveyor belt 20 moves forward, and the wrapping paper is gradually gathered by the gathering mechanism to achieve preliminary packaging of the laver sheets. After the preliminary packaging is completed, the label can be attached by the labeling mechanism, and the laver is fully automated. After the label is attached, the finished product comes to the bottom of the first conveyor belt 20, and the finished product is pulled out from the fixed frame 18 under the action of external force. While the overall automated operation is achieved, the hygiene issues in the laver packaging process are guaranteed to ensure food safety.

[0063] Embodiment 2

[0064] The difference between this embodiment and the first embodiment lies in that:

[0065] The labeling mechanism is located below the first conveying mechanism. The labeling mechanism can be lifted and lowered, and contacts the semi-finished product completed and gathered at the fixed frame to realize the fitting of the label and the semi-finished product.

[0066] Embodiment Three

[0067] This embodiment provides a working method of laver packaging machinery, including the following contents:

[0068] The wrapping paper is preliminarily cut by the cutting mechanism;

[0069] The wrapping paper 14 is made to enter between the first cylinder body and the second cylinder body through the third conveying mechanism, and the side of the wrapping paper extends beyond the first cylinder body;

[0070] The laver slices 10 fall onto the wrapping paper 14 from above the second cylinder body through the second conveying mechanism;

[0071] The air suction mechanism 15 works to adsorb the wrapping paper 14, and the wrapping paper drives the laver slices 10 to fall onto the first conveying mechanism through the first cylinder body 6;

[0072] The wrapping paper containing the laver slices 10 advances along with the advancement of the first conveying mechanism 16. During the advancement process, the gathering mechanism gathers the wrapping paper to form a semi-finished product;

[0073] After the gathering is completed, labeling is carried out manually or the semi-finished product is labeled through the labeling mechanism to form a finished product;

[0074] After the labeling is completed, the finished product is manually pushed out from the fixed frame at the lower part of the first conveying mechanism 16 where the finished product runs.

[0075] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
