Description

Technical Field

[0001] This invention belongs to the field of kelp roll processing equipment, and more specifically, relates to a kelp roll forming equipment. Background Technology

[0002] Salted kelp rolls use well-salted cooked kelp as the raw material, preserving the original flavor of the kelp. Currently, all salted kelp rolls on the market are made by hand, where kelp sheets are rolled into rolls and then skewered. This traditional method of processing salted kelp rolls suffers from low production efficiency and is time-consuming and labor-intensive. With rising living standards, fewer and fewer people are willing to engage in the manual production of salted kelp rolls, while the labor costs paid by businesses are increasing year by year. Therefore, there is an urgent need to improve the automation level of salted kelp roll processing to help businesses improve their economic efficiency.

[0003] Currently, the production of kelp rolls is mainly done by hand, using auxiliary materials such as cotton thread and bamboo skewers to secure them and prevent them from unraveling. Since most kelp rolls on the market are rolled and skewered manually, the production efficiency is low, and it is time-consuming and labor-intensive. In addition, long-term contact with salted kelp can also cause significant damage to the hands of production workers.

[0004] Rolling machines are currently widely used in the packaging industry, such as for rolling household goods. However, they are less commonly used for rolling food. In existing rolling machines, the clamping plates are usually driven to move relative to each other by a cylinder or electric push rod. The two clamping plates on the turntable are also driven to rotate by a motor. The cylinder (or electric push rod) has to rotate with the turntable, which is not conducive to the routing of air pipes or power cords. The wires are prone to getting tangled and worn.

[0005] Furthermore, in some existing kelp rolling and skewering equipment, after the kelp is rolled into a roll on the rolling mechanism, it needs to be clamped by a clamp to separate it from the clamp plate before skewering. That is, the clamp has to carry the kelp roll outside the clamp plate for skewering, which increases the power mechanism and control system. Moreover, the kelp is easily cut and scattered by the clamp plate when it is clamped and separated from the clamp plate. In addition, the clamping force is difficult to control. If it is too large, the friction is too great, and the kelp roll is not easy to separate from the clamp plate. If it is too small, the clamp will move relative to the kelp roll, and the kelp roll will remain on the clamp plate, making it impossible for the clamp to remove the kelp roll. Summary of the Invention

[0006] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides a kelp roll forming device, wherein a conveyor belt conveyor transports kelp sheets, a rolling mechanism rolls the kelp sheets into kelp rolls, and a skewering mechanism pushes bamboo skewers into the kelp rolls for skewering, thereby completing the automated production of kelp rolls, which helps to improve production efficiency and reduce manual operation.

[0017] Preferably, each of the arc-shaped guide plates has a baffle extending from its inner wall to roll up the kelp on the clamp plate when the third motor moves with the support toward the motor housing closer to the third motor.

[0018] Preferably, the tag-threading mechanism includes a tag box, a tag-dispensing wheel, a tag-dispensing wheel drive mechanism, a tag hopper, and a tag-pushing mechanism, wherein:

[0019] The skewer is located outside the skewer box and installed on one side of the skewer box. The inner cavity of the skewer box is connected to the inner cavity of the skewer box. The skewer box has a slide for receiving bamboo skewers so that the bamboo skewers slide into the skewer box under their own weight.

[0020] The dispensing wheel is located inside the skewer box, and the outer circumference of the dispensing wheel cooperates with the outlet of the skewer bucket to prevent the bamboo skewers inside the skewer bucket from sliding down into the skewer box under the action of gravity.

[0021] The label-dispensing wheel drive mechanism is connected to the label-dispensing wheel to drive the label-dispensing wheel to rotate;

[0022] The outer circumferential surface of the skewer-dispensing wheel has multiple grooves arranged therein, so that a single bamboo skewer sliding down the slide falls into a single groove, and:

[0023] For each of the aforementioned channels, there are a first channel sidewall and a second channel sidewall arranged opposite to each other. The dispensing wheel is provided with a pushing surface connected to the first channel sidewall at a position corresponding to the first channel sidewall. The pushing surface is used to push away the bamboo sticks piled on the slide of the skewer when the dispensing wheel rotates, so that a single layer of bamboo sticks is formed between the pushing surface and the slide. The dispensing wheel is provided with a hook at a position corresponding to the second channel sidewall. The hook is used to hook a single bamboo stick that slides down from the slide and make the single bamboo stick slide into the channel along the second channel sidewall.

[0024] The inner wall of the skewer box is provided with a guide surface, and the bottom of the skewer box is provided with a receiving groove for allowing bamboo skewers that fall out of the channel to slide from the guide surface to the receiving groove and be received by the receiving groove. The skewer box is provided with a dispensing hole at the position corresponding to the receiving groove.

[0025] The pushing mechanism is used to push a single bamboo skewer in the receiving groove onto the kelp roll to achieve skewering.

[0026] Preferably, the skewering mechanism further includes a lifting mechanism mounted on the frame, the lifting mechanism being connected to the skewer box for driving the skewer box to move toward or away from the seaweed roll.

[0027] Preferably, the skewering mechanism further includes an anti-slip component mounted on the frame. The anti-slip component has a fixed plate and an anti-slip plate. The fixed plate is fixedly mounted on the frame, and the anti-slip plate is hinged to the fixed plate via a horizontal hinge shaft. The lower end of the anti-slip plate is used to contact the kelp roll to prevent the kelp roll from stretching and expanding. A return spring is provided between the anti-slip plate and the fixed plate, and the skewer box can push open the anti-slip plate during downward movement.

[0028] Preferably, the tag-threading mechanism further includes a tag box driving mechanism, wherein the tag box is driven by the tag box driving mechanism to move in a direction closer to or away from the clamp.

[0029] Preferably, the two clamping plates are a first clamping plate and a second clamping plate, and the skewer box can cooperate with the first clamping plate to clamp the seaweed roll, and:

[0030] The first clamping plate includes a first clamping plate body and two arching devices, wherein the first clamping plate body is hollow;

[0031] Each of the arching devices includes a button, a return spring, a rotating plate, a hinge shaft, and an arching plate. The button is located in a button hole at the top of the first clamping plate, and there is a gap between the inner wall of the button hole and the button to allow the button to move up and down. The return spring and the rotating plate are both located inside the first clamping plate. The return spring is vertically arranged, and its upper end is fixedly mounted on the button and its lower end is fixedly mounted on the first clamping plate. The rotating plate is hinged to the first clamping plate via the horizontal hinge shaft, and its first end is connected to the button. The second end of the rotating plate is fixedly connected to the arching plate, and the second end of the rotating plate is opposite to the first end of the rotating plate. The hinge shaft is located between the second end of the rotating plate and the first end of the rotating plate. The top of the arching plate has an upwardly arched curved surface.

[0032] There is a gap between the two arching plates to facilitate inserting bamboo skewers into the seaweed between the two arching plates;

[0033] The first clamping plate body is provided with holes at the positions corresponding to each of the arching plates, so that the curved surface of the top of the arching plate extends upward out of the first clamping plate body;

[0034] The sign box is provided with a notch at the position corresponding to each of the arched plates to accommodate the curved surface at the top of the arched plate;

[0035] The side of the tag box near the first clamping plate has a pressing part corresponding to each of the buttons, for pressing the button to drive the rotating plate to rotate, so that the curved surface of the top of the arching plate moves upward into the notch, thereby causing the seaweed roll wrapped on the first clamping plate to form an arched part.

[0036] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0037] 1) This invention uses a conveyor belt to transport kelp slices, a rolling mechanism to roll the kelp slices into kelp rolls, and a skewering mechanism to push bamboo skewers into the kelp rolls for skewering. The rolling mechanism, skewering mechanism and other mechanisms work together to realize the automated production of kelp from slices to rolls and the skewering of bamboo skewers into the kelp rolls, which helps to improve production efficiency and reduce manual operation.

[0038] 2) The rolling mechanism of this invention uses a second motor to rotate a gear, which drives two racks to move relative to each other. This allows the two clamping plates to move closer or further apart, thus clamping and releasing the kelp. The first motor rotates a drive wheel, which in turn drives a driven wheel, causing the clamping plates mounted on the racks to rotate, thereby rolling the kelp sheets into kelp rolls. The relative movement of the clamping plates is driven by a gear and rack mechanism, and the rotation is driven by a belt drive mechanism. This eliminates the need for traditional structures that use cylinders or electric push rods mounted on the clamping plates to drive their relative movement, thus avoiding problems with wiring difficulties or wire wear.

[0039] 3) This invention can hold kelp by using a skewer box and a first clamping plate together. At the same time, pressing a button on the skewer box causes the second end of the rotating plate to tilt up and move upward, so that the curved surface at the top of the arching plate lifts the kelp, thus making the kelp arched and forming an arched part. This makes it easier for bamboo skewers to be inserted into the arched part, which can reduce labor costs and reduce the injury to the hands of production personnel caused by salted kelp.

[0040] 4) This invention uses a skewer to hold bamboo skewers, allowing them to be stacked together. A single bamboo skewer is obtained through a groove on the skewer-dispensing wheel. After the skewer-dispensing wheel rotates to a set angle, the single bamboo skewer in the groove falls into the receiving groove under its own weight. Then, the bamboo skewer can be inserted into the outer seaweed roll by the skewer-pushing mechanism, which has a high degree of automation. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Referring to the accompanying drawings, a kelp rolling forming device includes a frame 100, a conveyor belt 2000, a rolling mechanism 1000, and a skewering mechanism 3000, wherein:

[0055] The conveyor belt 2000 is used to convey kelp sheets to the rolling mechanism 1000;

[0056] The rolling mechanism 1000 is mounted on the frame 100 and is used to roll the received kelp sheets into kelp rolls; wherein, the rolling mechanism 1000 has two parallel clamping plates 106 for clamping and winding the kelp.

[0057] The skewer-skewering mechanism 3000 is mounted on the frame 100 and is used to skewer bamboo sticks onto the kelp rolls on the rolling mechanism 1000.

[0058] Additionally, the present invention may include a belt conveyor 4000 for dropping the tagged seaweed rolls onto the conveyor for transport to other locations. Alternatively, if a belt conveyor 4000 is not used, a material frame can be used to collect the tagged seaweed rolls.

[0059] The winding mechanism 1000 includes a support 101, a first motor 102, a second motor 103, a belt drive mechanism 104, a gear and rack mechanism 105, and two parallel clamping plates 106, wherein:

[0060] The first motor 102 and the second motor 103 are both mounted on the support 101, and the output shafts of the first motor 102 and the second motor 103 are parallel to each other.

[0061] The belt drive mechanism 104 includes a driving wheel 107, a driven wheel, and a drive belt 109 connecting the driving wheel 107 and the driven wheel. The gear 110 and rack 111 include a gear 110 and two parallel racks 111. Each rack 111 meshes with the gear 110, and each rack 111 is mounted with a clamping plate 106. Each rack 111 is slidably mounted on the driven wheel. When the gear 110 rotates, the two racks 111 can move relative to the drive wheel, thereby allowing the two clamping plates 106 to move closer to or further away from each other.

[0062] The drive wheel 107 and gear 110 are respectively mounted on the output shafts of the first motor 102 and the second motor 103. The first motor 102 drives the drive wheel 107 to rotate, and the drive wheel 107 drives the driven wheel to rotate through the transmission belt 109. The second motor 103 drives the gear 110 to rotate, and the rotation of the gear 110 can drive the rack 111 to move relative to the transmission wheel and slide on the transmission wheel.

[0063] A through hole 117 is provided along the axial direction of the driven wheel. The through hole 117 facilitates the installation and arrangement of the gear 110 and the rack 111. The gear 110 is located in the through hole 117.

[0064] Furthermore, the present invention also includes a winding mechanism drive mechanism 112 mounted on the frame 100. The winding mechanism drive mechanism 112 includes a third motor 113 and a lead screw mechanism 114 mounted on the output shaft of the third motor 113. The output shaft of the third motor 113 is parallel to the output shaft of the first motor 102. The winding mechanism 1000 is mounted on the lead screw mechanism 114, and preferably the support 101 is mounted on the lead screw mechanism 114. Preferably, there are multiple winding mechanism drive mechanisms 112, which facilitates the rapid movement of the support 101 and also makes the force on the lead screw mechanism 114 more balanced and distributed, thereby improving the service life of the lead screw mechanism 114.

[0065] Furthermore, the present invention also includes two concentrically arranged arc-shaped guide plates 115 mounted on the frame 100, wherein the inner diameter of one arc-shaped guide plate 115 is larger than the inner diameter of the other arc-shaped guide plate 115, and the two arc-shaped guide plates 115 surround the clamping plate 106. The arc-shaped guide plates 115 have an arc-shaped structure and mainly assist the clamping plate 106 during the rolling stage, allowing the kelp to be successfully rolled up under the clamping of the clamping plate 106, preventing some kelp from rotating with the clamping plate 106 due to excessive toughness and failing to roll up. One of the arc-shaped guide plates 115 is closer to the clamping plate 106, which allows the kelp to be rolled up more compactly, preventing the kelp from being too large after rolling and unable to fall onto the conveyor belt. Another arc-shaped guide plate 115 plays an auxiliary role and is relatively far from the clamping plate 106. Firstly, it allows the kelp to roll up better. Secondly, compared to the situation where the other arc-shaped guide plate 115 clamps the kelp roll with the clamping plate 106, the kelp roll between this arc-shaped guide plate 115 and the clamping plate 106 is clamped more loosely, leaving enough gaps to allow the kelp roll to pass smoothly through the gaps between this arc-shaped guide plate 115 and the kelp roll and fall off the clamping plate 106.

[0066] Furthermore, each of the arc-shaped guide plates 115 has a baffle 116 extending from its inner wall to roll off the seaweed on the clamping plate 106 when the third motor 113 moves with the support 101 toward the motor housing of the third motor 113. The baffle 116, as an auxiliary structure of the arc-shaped guide plate 115, extends inward from the shape of the arc-shaped guide plate 115. When the clamping plate 106 retracts, the guide plate baffle 116 restricts one end of the seaweed, causing it to be rolled off the clamping plate 106 and thus detach from it.

[0067] In the coiling mechanism 1000 of the present invention, the first motor 102 drives two clamping plates 106 to rotate via a belt drive mechanism 104, thereby completing the coiling of the kelp. The driving mechanism 112 of the coiling mechanism drives the support 101 and the clamping plates 106 to move left and right, completing the unwinding of the kelp after it has been coiled and tagged. The clamping plates 106 need to perform clamping and rotating actions. The clamping action is performed by a gear and rack mechanism 105. The second motor 103 drives the gear 110 to move the two racks 111, completing the clamping and loosening actions of the two clamping plates 106. The coiling and rotating action is completed by the belt drive mechanism 104. Since the driven wheel of the slidingly mounted rack 111 only allows the rack 111 to slide, the belt drive mechanism 104 will cause the driven wheel to drive the rack 111 to rotate, thus completing the coiling action.

[0068] It is important to note that during the rolling process, the first motor 102 of the drive belt transmission mechanism 104 and the second motor 103 of the drive gear 110 must rotate simultaneously. That is, when the clamping plate 106 needs to rotate for rolling, while the first motor 102 drives the driven wheel to rotate, the second motor 103 must also drive the gear 110 to rotate, so that there is no relative movement between the gear 110 and the rack 111, that is, the two are kept relatively stationary. Otherwise, the driven wheel will not be able to rotate, the teeth will get stuck, and the clamping plate 106 will loosen its grip on the kelp due to centrifugal motion.

[0069] The tag-threading mechanism 3000 includes a tag box 301, a tag-dispensing wheel 302, a tag-dispensing wheel drive mechanism, a tag hopper 303, and a tag-pushing mechanism, wherein:

[0070] The skewer 303 is located outside the skewer box 301 and installed on one side of the skewer box 301. The inner cavity of the skewer 303 is connected to the inner cavity of the skewer box 301. The skewer 303 has a slide 304 for receiving bamboo skewers. The slide 304 is inclined relative to the horizontal plane. The slide 304 can be flat or curved so that the bamboo skewers slide into the skewer box 301 under their own weight. After entering the skewer 303, the bamboo skewers are arranged on the slide 304 inside the skewer 303.

[0071] The skewer dispensing wheel 302 is located inside the skewer box 301, and the outer circular surface 305 of the skewer dispensing wheel 302 cooperates with the outlet 306 of the skewer bucket 303 to prevent the bamboo skewers in the skewer bucket 303 from sliding down into the skewer box 301 under the action of gravity.

[0072] The label-dispensing wheel drive mechanism is connected to the label-dispensing wheel 302 to drive the label-dispensing wheel 302 to rotate;

[0073] The outer circular surface 305 of the skewer-dispensing wheel 302 is circumferentially arranged with multiple channels 307 so that a single bamboo skewer sliding down the slide 304 falls into a single channel 307, and:

[0074] Each of the aforementioned channels 307 includes a first channel sidewall 308 and a second channel sidewall 309 disposed opposite to each other. The skewer dispensing wheel 302 is provided with a skewer pushing surface 310 connected to the first channel sidewall 308 at a position corresponding to the first channel sidewall 308. The skewer pushing surface 310 is used to push away the bamboo skewers piled on the slide 304 of the skewer hopper 303 when the skewer dispensing wheel 302 rotates, so that a single layer of bamboo skewers is formed between the skewer pushing surface 310 and the slide 304. The skewer dispensing wheel 302 is provided with a hook at a position corresponding to the second channel sidewall 309. The hook is used to hook a single bamboo skewer that slides down from the slide 304 and make the single bamboo skewer slide along the second channel sidewall 309 into the channel 307.

[0075] The inner wall of the skewer box 301 is provided with a guide surface 311, and the bottom of the skewer box 301 is provided with a receiving groove 312 for allowing bamboo skewers that fall out of the channel 307 to slide from the guide surface 311 to the receiving groove 312 and be received by the receiving groove 312. The skewer box 301 is provided with a dispensing hole at the position corresponding to the receiving groove 312. Preferably, two parallel limiting plates are installed on the guide surface 311 to prevent the bamboo skewers from sliding out of the guide surface 311.

[0076] The skewer pushing mechanism is preferably installed on the frame 100 and is used to push a single bamboo skewer in the skewer receiving groove 312 into the kelp roll to achieve skewering.

[0077] Furthermore, the skewer-feeding mechanism 3000 of the present invention also includes a lifting mechanism 313 mounted on the frame 100. The lifting mechanism 313 is connected to the skewer box 301 and is used to drive the skewer box 301 to move towards or away from the seaweed roll for easier skewering. The lifting mechanism 313 can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0078] Furthermore, the skewer-piercing mechanism 3000 also includes an anti-slip component 314 mounted on the frame 100. The anti-slip component 314 has a fixing plate 315 and an anti-slip plate 316. The fixing plate 315 is fixedly mounted on the frame 100, and the anti-slip plate 316 is hinged to the fixing plate 315 via a horizontal hinge shaft. The lower end of the anti-slip plate 316 is used to contact the kelp roll to prevent the kelp roll from stretching and expanding. A return spring 317 is provided between the anti-slip plate 316 and the fixing plate 315. The skewer box 301 can push open the anti-slip plate 316 during downward movement. When the kelp roll is finished rolling on the clamping plate of the winding mechanism, since the end of the kelp exposed on the clamping plate (the end clamped by the clamping plate is the head end) is above the clamping plate, and the kelp has a certain degree of flexibility, the anti-slip plate 316 is needed to block the end of the kelp to prevent the end of the kelp from continuing to slide and to prevent the kelp from becoming too large due to natural stretching and making it impossible to skewer.

[0079] The skewer-threading mechanism 3000 of this invention mainly completes the skewering of the kelp rolls wound on the two clamps of the winding mechanism. The lifting mechanism 313 is responsible for driving the skewer box 301 to move up and down, and the skewer-threading device is responsible for completing the skewer-threading work of the kelp. In the skewer-threading mechanism, bamboo skewers enter from the skewer hopper 303 and accumulate near the outlet 306 of the skewer hopper 303. The outlet 306 of the skewer hopper 303 is closed by the outer circular surface 305 of the skewer-feeding wheel 302 cooperating with the outlet 306 of the skewer hopper 303 to prevent the bamboo skewers from sliding down into the skewer box 301 under their own weight. The groove 307 on the outer circular surface 305 of the skewer-feeding wheel 302 cooperates with the outlet 306 of the skewer hopper 303 to open the outlet 306 of the skewer hopper 303, so that a single bamboo skewer can fall into a single groove 307. The matching wheel drive mechanism drives the hook on the matching wheel 302 to hook up a single bamboo stick and rotate it with the stick-threading wheel. After the matching wheel 302 rotates to a certain angle, the bamboo stick will fall out of the groove 307 under its own weight and onto the guide surface 311. Then the bamboo stick enters the receiving groove 312 along the guide surface 311, ready to be pushed by the stick-pushing mechanism to complete the stick-threading process.

[0080] The two clamping plates 106 are respectively the first clamping plate and the second clamping plate. The first clamping plate and the skewer box 301 can cooperate to clamp the seaweed roll. The skewer box 301 is a movable mold. The skewer box 301 is driven by the skewer box driving mechanism 212 to move towards or away from the first clamping plate. The skewer box driving mechanism 212 can be a cylinder, a hydraulic cylinder, or an electric push rod. The skewer box driving mechanism 212 can be directly or indirectly mounted on the frame 100. The first clamping plate can also be directly or indirectly mounted on the frame 100. The first clamping plate can be movable or fixed, and:

[0081] The first clamping plate includes a clamping plate body 203 and two arching devices 204. The clamping plate body 203 is hollow and has an inner cavity.

[0082] Each of the arching devices 204 includes a button 205, a return spring 206, a rotating plate 207, a hinge pin 208, and an arching plate 209. The button 205 is disposed in a button hole at the top of the clamping plate body 203, and there is a gap between the inner wall of the button hole and the button 205 to allow the button 205 to move up and down. The return spring 206 and the rotating plate 207 are both located inside the clamping plate body 203. The return spring 206 is vertically arranged, and its upper end is fixedly mounted on the button 205 while its lower end is fixedly mounted on the clamping plate body 203. The rotating plate 207 is hinged to the clamping plate body 203 via the horizontal hinge pin 208, and the first end of the rotating plate 207 is connected to the button 205. 5. It can be fixedly connected or movably connected. For example, the first end of the rotating plate 207 can be made into a fork that rests on the connecting rod connected to the lower end of the button 205. The button 205 presses on the first end of the rotating plate 207, so the button 205 and the rotating plate 207 can move relative to each other, and their movements do not affect each other. The second end of the rotating plate 207 is fixedly connected to the arching plate 209. The second end of the rotating plate 207 is opposite to the first end of the rotating plate 207, and the hinge 208 is located between the second end of the rotating plate 207 and the first end of the rotating plate 207. The top of the arching plate 209 is provided with an upwardly arched curved surface, which is preferably an arc surface. The top of the curved surface can be moved to contact the top of the notch 210, so that it can be fixed together with the skewer box 301 to hold the kelp. The kelp will not move when skewering, which facilitates the subsequent skewering work.

[0083] There is a gap between the two arching plates 209 to facilitate inserting bamboo skewers into the kelp between the two arching plates 209.

[0084] The clamping plate 203 has holes at positions corresponding to each of the arching plates 209, so that the curved surface of the top of the arching plate 209 extends upward from the clamping plate 203. The size of the holes should not affect the vertical movement of the arching plate 209. Preferably, there is a gap between the inner wall of the hole and the arching plate 209 extending into the hole, so that the arching plate 209 can enter the notch 210 after extending out of the clamping plate 203.

[0085] The tag box 301 is provided with a notch 210 at the position corresponding to each of the arched plates 209 to accommodate the curved surface at the top of the arched plate 209; the size of the notch 210 should not affect the normal up and down movement of the curved surface of the arched plate 209.

[0086] The label box 301 has a pressing part on the side near the first clamping plate, corresponding to the position of each button 205. This pressing of a button 205 causes the rotating plate 207 to rotate, thereby moving the curved surface of the top of the arching plate 209 upwards into the notch 210, thus forming an arched portion of the seaweed roll wrapped around the clamping plate body 203. If the button 205 is fixedly connected to the first end of the rotating plate 207, the pressing surface is relatively smooth, allowing the button 205 to slide relative to the pressing surface during the rotation of the rotating plate 207. Alternatively, the rotating plate 207 has good flexibility, allowing it to bend and deform elastically, so that the rotating plate 207 also rotates around the hinge axis 208 during the downward movement of the button 205. In short, it is essential to ensure that the downward movement of the button 205 and the rotation of the rotating plate 207 occur simultaneously and normally, without damaging the button 205 or the rotating plate 207.

[0087] Furthermore, a limiting block 211 is also installed on the arching plate 209. The limiting block 211 is located inside the clamping plate body 203 to limit the stroke of the arching plate 209 extending out of the clamping plate body 203, so as to prevent the label box 301 from pressing the arching plate 209 and the button 205 respectively at the notch 210 and the pressing surface corresponding to the button 205, thereby damaging the rotating plate 207.

[0088] The two clamps have already rolled the kelp into rolls, which makes it easy to make the kelp rolls arch, eliminating the need to transfer the kelp rolls to other devices to arch them, thus improving work efficiency.

[0089] During operation, move the skewer box 301 toward the direction of the first clamping plate. Press the button 205 on the pressing surface of the skewer box 301. The button 205 moves downward and drives the first and second ends of the rotating plate 207 to rotate around the hinge shaft 208. The second end of the rotating plate 207 tilts up and moves upward to make the curved surface at the top of the arching block lift up the kelp, thus making the kelp arch and forming an arched part, which is convenient for skewering.

[0090] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
