Description

Technical Field

[0001] This invention relates to the technical field of food processing equipment, and in particular to a barbecue skewer device. Background Technology

[0002] With the rapid development of my country's economy, the status of the tertiary industry has been greatly enhanced, and the catering industry has developed rapidly. Local delicacies such as barbecue and skewers have gradually spread throughout the country, resulting in a huge demand for ingredients.

[0003] As living standards improve, more and more people enjoy eating barbecue skewers. Various meats and vegetables are cut into pieces, skewered, and then grilled. Before grilling, the meat skewers need to be skewered one by one.

[0004] In the barbecue industry, almost all types of skewers are made by hand, such as meat, bean products, vegetarian food, staple food, and vegetables. According to the size of each food, they can be divided into small square skewers (beef skewers, lamb skewers), round skewers (meatball skewers), columnar skewers (ham, dried tofu, corn), irregular skewers (chicken wings), etc.

[0005] Because there are many types of barbecue, while skewering by hand provides a more uniform result, it is too tedious, inefficient, and time-consuming. For larger barbecue restaurants, the sheer volume of skewers necessitates a greater workforce, leading to increased costs and hindering their healthy development.

[0006] While similar machines have appeared on the market, the applicant has found that the existing technology has at least the following technical problems:

[0007] Currently available machines for skewering beef, lamb, and pork require the meat to be placed in a tray before being fed into the skewer conveyor, a cumbersome process that is not suitable for large-scale skewer production. Furthermore, they cannot skewer different sizes of meat, which are diverse in shape and size for grilling, and cannot replace manual labor, significantly reducing their applicability. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a barbecue skewering device to solve the technical problems of existing skewering machines having a cumbersome skewering process, being unsuitable for skewering large quantities of meat, and having a limited range of applications.

[0009] To achieve the above objectives, the present invention provides a barbecue skewering device, including a base, a single-skewer skewering device, and a double-skewer skewering device. Both the single-skewer skewering device and the double-skewer skewering device are fixed on the base.

Each storage groove has a through groove communicating with the receiving cavity. The suction roller is connected to a pressure chamber mechanism, and the storage roller is connected to a rotating mechanism. Each time the storage roller rotates, two of the storage grooves always correspond to the infeed port and the label dropping port of the infeed roller, respectively. The suction roller has a suction port, and the suction port, the through groove, and the infeed port form a channel that allows airflow to pass through.

[0016] Preferably, the feeding mechanism includes a feeding seat and a trough structure, a conveying component, and a transmission component located on the feeding seat.

The trough structure is located below the outlet of the material pipe component and is connected to the conveying component. The transmission component is provided with a limiting groove. The pressing mechanism can push the material at the outlet of the material pipe component into the trough of the trough structure. The conveying component can drive the trough structure to move and cause the skewers of meat on the trough structure to fall into the limiting groove on the transmission component.

[0017] Preferably, the single-skewer device further includes a length adjustment mechanism. After the meat is skewered, it can be conveyed to the length adjustment mechanism through the feeding mechanism.

[0022] The material blocking plate is positioned above the material pushing plate and abuts against the bottom of the material storage mechanism. The material blocking plate is connected to the cam linear mechanism via a connector. The power component can simultaneously drive the material pushing plate and the material blocking plate to perform reciprocating linear motion. When the power component drives the material blocking plate back to the origin, the last layer of material in the material storage mechanism can fall onto the material platform.

[0027] The barbecue skewering equipment provided by this invention includes a base, a single-skewer skewering device, and a double-skewer skewering device. Both the single-skewer and double-skewer skewering devices are fixed on the base. The single-skewer skewering device, through the design of a linked hopper mechanism, a pressing mechanism, a skewer feeding mechanism, and a feeding mechanism, ensures that a stable one bamboo skewer reaches the feeding mechanism in each working cycle. It has the advantages of clear working procedures and reliable equipment operation. It is suitable for skewering beef, lamb, chicken, chicken gizzards, chicken hearts, and other skewered products, and fully realizes the entire process of automatic skewer loading and automatic skewering. The skewers are uniform in size, clean and hygienic, improve work efficiency, and are conducive to the skewering of large batches of meat. The double-skewer skewer device is suitable for larger items, such as mushrooms, bread slices, or fish balls. Because of the larger size, using two skewers is more secure. Therefore, a double-skewer feeding mechanism is designed to dispense two skewers simultaneously. The pushing mechanism has a material platform. After the lifting mechanism is pre-adjusted to the appropriate position, the material is placed in the hopper. The pushing mechanism then operates, pushing the bottom layer of material from the hopper onto the material platform with each push, and also pushing the material on the platform under the pressing mechanism. The pressing mechanism then compresses the material. Afterward, the double-skewer feeding mechanism delivers the skewers. Once skewered, the material is pushed into the skewer tray by the next action of the pushing mechanism, thus completing a standard skewer. This invention provides an automatic skewering and feeding process, improving work efficiency and having a wide range of applications, capable of skewering different types of materials.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0062] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0063] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0064] See Figure 30 and Figure 31This invention provides a barbecue skewer device, including a base 20, a single-skewer skewer device, and a double-skewer skewer device. Both the single-skewer and double-skewer skewer devices are fixed on the base 20 and can be detachably connected to the base 20 by bolts, facilitating the movement of the device. The single-skewer skewer device includes a hopper mechanism 1, a pressing mechanism 2, a skewer feeding mechanism 3, and a feeding mechanism 4. The hopper mechanism 1 is connected to a material pipe assembly 5, and the meat pieces in the hopper mechanism 1 can be conveyed to the outlet of the material pipe assembly 5. The pressing mechanism 2 is located above the material pipe assembly 5 and can push the material at the outlet of the material pipe assembly 5 into the trough of the feeding mechanism 4. The skewer feeding mechanism 3 can skewer the meat pieces in the trough of the feeding mechanism 4. After the meat pieces are skewered, they can be conveyed to the skewer tray by the feeding mechanism 4.

[0065] The double-label material threading device includes a storage mechanism 15, a pressing mechanism 16, a double-label delivery mechanism 17, a pushing mechanism 18, and a lifting mechanism 19. The pushing mechanism 18 has a material platform 184. After material is placed in the storage mechanism 15, the pushing mechanism 18 allows the bottom layer of material in the storage mechanism 15 to fall onto the material platform 184, and pushes the material on the material platform 184 below the pressing mechanism 16. The pressing mechanism 16 moves downward to compress the material on the material platform 184. The double-label delivery mechanism 17 is mounted on the lifting mechanism 19, and the lifting mechanism 19 can cause the labels on the double-label delivery mechanism 17 to be concentric with the material on the pushing mechanism 18. After the material is tagged, it can be pushed into the threading tray by the pushing mechanism 18. After the lifting mechanism 19 is pre-adjusted to a suitable position, and the material is placed in the storage mechanism 15, the pushing mechanism 18 begins operation. Each push of the pushing mechanism 18 allows the bottom layer of material in the storage mechanism 15 to fall onto the material platform 184, and also pushes the material on the platform under the pressing mechanism 16. At this time, the pressing mechanism 16 begins to operate to compact the material. Then, the double-skewer feeding mechanism 17 begins to feed the skewers. After the material is skewered, it will be pushed into the skewer tray by the next action of the pushing mechanism 18. At this point, a standard skewer of meat is completed. The process of skewering and feeding is fully automated, and the skewers are uniform in size, clean and hygienic, improving work efficiency.

[0066] The single-skewer material skewer device provided in this embodiment is mainly designed for skewering smaller materials, such as small pieces of meat like beef, mutton, and pork skewers. It includes a hopper mechanism 1, a pressing mechanism 2, a skewer feeding mechanism 3, and a feeding mechanism 4.

[0067] See Figures 1-12Specifically, the hopper mechanism 1 includes a hopper shell 11, a drive mechanism 12, a transmission mechanism 13, and a spiral pushing mechanism 14 disposed inside the hopper shell 11. The hopper shell 11 is connected to a material pipe assembly 5. The transmission mechanism 13 is connected between the drive mechanism 12 and the spiral pushing mechanism 14. The drive mechanism 12 can drive the spiral pushing mechanism 14 through the transmission mechanism 13 to push the material inside the hopper shell 11 into the outlet of the material pipe assembly 5.

[0068] The spiral pushing mechanism 14 includes a pushing shaft and spiral blades. The spiral blades are fixedly disposed on the outer surface of the pushing shaft. One end of the pushing shaft is connected to the driving mechanism 12 through the transmission mechanism 13, and the other end of the pushing shaft is connected to the inner wall of the hopper shell 11 through a short shaft. The hopper shell 11 includes a shell body 111 and a U-shaped partition 112 disposed inside the shell body 111. The U-shaped partition 112 is connected to two first sides disposed opposite to each other on the shell body 111. The area enclosed by the U-shaped partition 112 and the first sides forms a hopper for placing materials. The spiral pushing mechanism 14 is disposed inside the hopper.

[0069] The U-shaped partition 112 includes a first partition, a second partition, and a connecting part. The connecting part is used to connect the first partition and the second partition. The first partition includes a first upper vertical plate, a first inclined plate, and a first lower vertical plate connected from top to bottom. The second partition includes a second upper vertical plate, a second inclined plate, and a second lower vertical plate connected from top to bottom. The distance between the first upper vertical plate and the second upper vertical plate is greater than the distance between the first lower vertical plate and the second lower vertical plate. The spiral pushing mechanism 14 is disposed between the first lower vertical plate and the second lower vertical plate.

[0070] The single-skewer device provided by this invention is mainly designed for skewering smaller materials, such as small pieces of meat like beef, lamb, and pork skewers. Ordinary skewers are typically made of five pieces of meat, arranged in a "meat and fat" pattern (three pieces of meat, two pieces of fat), so the material storage mechanism 1 has five inlets. Materials are simply added sequentially. For details, see [link to details]. Figure 4 The hopper shell 11 has 5 interconnected U-shaped partitions 112 inside. Two adjacent U-shaped partitions 112 are connected, and two U-shaped partitions 112 on both sides are respectively connected to the second side of the corresponding shell body 111.

[0071] In addition, the hopper mechanism 1 also includes a protective cover, which has a cavity for housing the drive mechanism 12 and the transmission mechanism 13. The protective cover is fixedly mounted on the hopper shell 11, which increases the safety of the entire device.

[0072] See Figure 5 and Figure 6The pressing mechanism 2 includes a pressing housing 21, a driving part 22, a transmission part 23, and a pressing part 24. The driving part 22 and the transmission part 23 are disposed inside the pressing housing 21, and the pressing housing 21 is fixedly disposed above the material tube assembly 5. The transmission part 23 is disposed between the driving part 22 and the pressing part 24.

[0075] When the meat is pressed into the feed trough structure, the skewers enter the feed roller 31 from the skewer compartment 39. The pressure chamber mechanism 36 starts operating, driving the suction roller 33 to suck up the skewers. At the same time, the rotating motor 341 operates, causing the skewers sucked up by the suction roller 33 to enter the storage roller 32, and then be carried by the storage roller 32 into the dropping groove 371. At this time, the pushing motor 351 starts operating, quickly pushing the skewers in the dropping groove 371.

The trough structure is located below the outlet of the material pipe component 5 and is connected to the conveying component 6. The transmission component is provided with a limiting groove. The pressing mechanism 2 can push the material at the outlet of the material pipe component 5 into the trough of the trough structure. The conveying component 6 can drive the trough structure to move and can make the skewers of meat on the trough structure fall into the limiting groove on the transmission component.

[0078] The feeding base includes a first feeding base 41 and a second feeding base 42.

[0082] In addition, the single-skewer device provided in this example also includes a length adjustment mechanism. After the meat pieces are skewered, they can be conveyed to the length adjustment mechanism via the feeding mechanism 4. After the length of the skewer is adjusted by the length adjustment mechanism, it can be conveyed to the skewer tray via the feeding mechanism 4. The length adjustment mechanism can control the length of small meat skewers, which can meet the needs of more barbecue restaurants. It is convenient to use and has wide applicability.

The two second support columns 423 are disposed opposite to each other at the rear end of the base plate 421, and a second driven shaft 83, a third driven sprocket 86, and a fourth driven sprocket 87 are disposed between the two second support columns 423. One end of the second drive shaft 82 passes through the first support column 422 and is connected to the fourth transmission wheel 76. The first spiral shaft 95 and the second spiral shaft 96 are connected to the intermediate support frame 424. The second spiral shaft 96 is connected to the power unit 91 via the transmission unit 23, and the second spiral shaft 96 is connected to the first spiral shaft 95 via the gear and belt transmission structure 93. A guide connecting plate 10 is provided between the first feeding seat 41 and the first support column 422. Under the drive of the conveying assembly 6, the meat skewers on the trough structure can fall into the limiting grooves of the third chain 88 and the fourth chain 89 along the guide connecting plate 10.

[0084] In this embodiment, the transmission unit 92 includes a first gear 921, a second gear 922, and a first belt 923. The first gear 921 is connected to the output shaft of the power unit 91, and the second gear 922 is connected to the second spiral shaft 96. The first gear 921 and the second gear 922 are connected by the first belt 923. The gear belt transmission structure 93 includes a third gear 931, a fourth gear 932, and a second belt 933. The third gear 931 is connected to the second spiral shaft 96, and the fourth gear 932 is connected to the first spiral shaft 95. The third gear 931 and the fourth gear 932 are connected by the second belt 933.

[0085] The length adjuster 97 includes a handle 971, a first rod 972, a second rod 973, a first baffle 974, and a second baffle 975. Both the first rod 972 and the second rod 973 are connected to the handle 971. The first rod 972 passes through the conveyor base 81 and connects to the first baffle 974. The second rod 973 passes through the conveyor base 81 and connects to the second baffle 975. The first rod 972 is located above the third chain 88 and the fourth chain 89 to allow the material to pass through. The first baffle 974 is located above the second baffle 975. The upper surfaces of the first baffle 974 and the second baffle 975 have gaps with the bottom of the first spiral shaft 95. The fixing nut 94 can move from top to bottom within the second feed seat 42 to fix the second rod 973; and it can move from bottom to top within the conveyor base 81 to release the fixation of the second rod 973.

[0086] The length of the meat skewer is set by pulling the length adjuster 97 and adjusting the distance between the first baffle 974, the second baffle 975 and the intermediate support frame 814. The length adjuster 97 is fixed by rotating the fixing nut 94. The skewered meat falls from the conveying assembly 6 onto the third chain 88 and the fourth chain 89. After passing through the first spiral shaft 95 and the second spiral shaft 96 of the adjustment part, the threads on the first spiral shaft 95 and the second spiral shaft 96 drive the meat pieces on the skewer to move in a small range, so that the meat skewer can be evenly changed to the appropriate length.

[0087] When the meat falls into the trough of the trough structure, the conveying component 8 stops, and then the skewer feeding mechanism 3 will skewer the meat once. After skewering, the skewered meat will be conveyed by the conveying component 8 to the position between the first spiral shaft 95 and the second spiral shaft 96. When the meat skewer passes the first spiral shaft 95 and the second spiral shaft 96, it will be automatically adjusted to the appropriate length, and then the conveying component 8 will transport it to the plate for placing skewers.

[0088] When using this single-skewer device, the meat is first placed into the hopper mechanism 1. The spiral pushing mechanism 14 in the hopper mechanism 1 pushes the meat into the outlet of the material pipe assembly 5. The pressing mechanism 2 presses the meat into the trough of the feeding mechanism 4. The skewer feeding mechanism 3 then works to skewer the meat. After the meat skewer is successfully skewered, the feeding mechanism 4 starts to operate. When the meat skewer is conveyed by the feeding mechanism 4 to the length adjustment mechanism 9 (the length adjuster 97 is adjusted to the appropriate size in advance and then fed into the skewer tray by the feeding mechanism 4), a standard meat skewer is completed.

[0089] See Figures 20-29 The double-sticker stringing device in this embodiment includes a storage mechanism 15, a pressing mechanism 16, a double-sticker feeding mechanism 17, a pushing mechanism 18, and a lifting mechanism 19. Specifically, the pushing mechanism 18 includes a blocking plate 181, a power component 182, a pushing plate 183, and a material platform 184. When the pushing mechanism 18 starts to operate, each time the pushing mechanism 18 pushes, the bottom layer of material in the storage mechanism 15 can fall onto the material platform 184. The power component 182 is connected to the pushing plate 183 through a cam linear mechanism 185, and the power component 182 can drive the pushing plate 183 to perform linear reciprocating motion through the cam linear mechanism 185 to push the material on the material platform 184 to below the pressing mechanism 16.

[0090] The material blocking plate 181 is positioned above the pusher plate 183 and abuts against the bottom of the storage mechanism 15. The material blocking plate 181 is connected to the cam linear mechanism 185 via a connector. The power component 182 can simultaneously drive the pusher plate 183 and the material blocking plate 181 to perform reciprocating linear motion. When the power component 182 drives the material blocking plate 181 back to the origin, the last layer of material in the storage mechanism 15 can fall onto the material platform 184.

[0091] After the material is placed into the hopper, the bottom layer of material is placed on the material platform 184. The power unit 182 starts to operate, driving the pusher plate 183 to push the material on the material platform 184 into the lower pressing mechanism 16. During the pushing process, in order to prevent the upper layer of material in the storage mechanism 15 from falling immediately, a blocking plate 181 is designed. In this embodiment, the blocking plate 181 moves together with the pusher plate 183. When the blocking plate 181 returns to the original position, the upper layer of material begins to fall. This cycle can be repeated.

[0092] The pressing mechanism 16 includes a pressing power structure 161, a pressing plate 162, and an elastic connector. The pressing power structure 161 is connected to the upper connector 163 through a gear meshing transmission mechanism 166. A lower connector 164 is fixedly connected above the pressing plate 162. An elastic connector is connected above the lower connector 164. There is a gap between the elastic connector and the bottom of the upper connector 163. A connecting cylinder assembly 165 is sleeved on the periphery of the lower end of the upper connector 163 and the periphery of the elastic connector. The pressing power structure 161 can drive the pressing plate 162 to move downward to press the material on the material platform 184.

[0093] When the material is below the pressing mechanism 16, the pressing power structure 161 starts to operate, driving the pressing plate 162 to press down and compress the material, ready for skewer insertion. The elastic connector uses a spring, which is designed to prevent the material from being too hard and damaging the parts, thus providing a cushioning effect.

[0094] The dual-signature delivery mechanism 17 includes a first delivery mechanism 171 and a second delivery mechanism 172. The first delivery mechanism 171 includes a first signature bin 1711, a first entry roller, a first storage roller, a first suction roller, a pusher 175, and a first drop structure. The first drop structure has a first drop groove. The first entry roller, the first storage roller, and the first suction roller are all located above the first drop groove. The first entry roller is located outside the first storage roller, and it has a first entry port and a first drop port communicating with the first signature bin. A first receiving cavity is provided inside a storage roller for accommodating a first suction roller, and four first storage slots are provided on the first storage roller at intervals. A first through groove is provided in the first storage slot and communicates with the first receiving cavity. The first suction roller is connected to a pressure chamber. The first storage roller is connected to a rotating part. Every time the first storage roller rotates, two first storage slots always correspond to the first entry port and the first drop port of the first entry roller respectively. The first suction roller is provided with a first suction port. The first suction port, the first through groove and the first entry port form a channel that allows airflow to pass through.

[0095] The second label delivery mechanism 172 includes a second label bin 1721, a second label entry roller, a second label storage roller, a second label suction roller, a label pushing part 175, and a second label dropping structure. The second label dropping structure has a second label dropping groove. The second label entry roller, the second label storage roller, and the second label suction roller are all located above the second label dropping groove. The second label entry roller is located outside the second label storage roller and has a second label entry port and a second label dropping port that communicate with the second label bin 1721. The second label storage roller has a second accommodating cavity for accommodating the second label suction roller, and four second label storage grooves are spaced apart on the second label storage roller. The second label storage grooves have a second through groove that communicates with the second accommodating cavity. The second label suction roller is connected to a pressure chamber 173, and the second label storage roller is connected to a rotating part 174. Each time the second label storage roller rotates, two second label storage grooves always correspond to the second label entry port and the second label dropping port of the second label entry roller, respectively. The second label suction roller has a second label suction port. The second label suction port, the second through groove, and the second label entry port form a channel that allows airflow to pass through. It should be noted that the principle of the double-signature delivery mechanism is the same as that of the single-signature delivery mechanism. The first entry roller, the first storage roller, the first suction roller, the first drop structure, the second entry roller, the second storage roller, the second suction roller, and the second drop structure are similar to the entry roller, storage roller, suction roller, and drop structure mentioned in the previous single-signature delivery mechanism, and will not be described again here.

[0096] The rotating part 174 includes a drive motor 1741 and a gear transmission structure. A first connecting shaft connected to the gear transmission structure is provided inside the first storage roller, and a second connecting shaft connected to the gear transmission structure is provided inside the second storage roller. The gear transmission structure includes a rotating shaft 1742, a first gear 1743, and a second gear 1744. The output shaft of the drive motor 1741 is connected to the rotating shaft 1742. The rotating shaft is provided with a toothed structure that cooperates with the first gear 1743 and the second gear 1744. The first gear 1743 is connected to the first connecting shaft, and the second gear 1744 is connected to the second connecting shaft. The end of the first connecting shaft away from the drive motor 1741 is fixed to the inner wall of the first storage roller, and the end of the second connecting shaft away from the drive motor 1741 is fixed to the inner wall of the second storage roller. The rotation of the drive motor 1741 can drive the first storage roller and the second storage groove to rotate simultaneously.

[0097] The pusher unit 175 in this embodiment includes a propulsion motor 1751, a cam linear reciprocating motion structure 1752, a first pusher unit 1753, and a second pusher unit 1754. The propulsion motor 1751 is connected to the cam linear reciprocating motion structure 1752, and the first pusher unit 1753 and the second pusher unit 1754 are both connected to the cam linear reciprocating motion structure 1752. The propulsion motor 1751 is used to drive the first pusher unit 1753 and the second pusher unit 1754 to perform linear reciprocating motion through the cam linear reciprocating motion structure 1752.

[0098] The lifting mechanism 19 in this embodiment includes a rotating nut 191, a lifting plate 192, and a transmission gear 193. The label feeding mechanism is disposed on the lifting plate 192. Rotating the rotating nut 191 can drive the lifting plate 192 to move in the vertical direction so that the labels on the label feeding mechanism are concentric with the material on the pushing mechanism 18.

[0099] Based on the height of each piece of material, rotate the rotating nut 191 to drive the transmission gear 193 to rotate. Since the label feeding mechanism is also on the lifting plate 192, the label feeding mechanism's label center is always concentric with the center of the material while the lifting plate 192 is raised, thus ensuring that each label can pass smoothly through the center of the material.

[0100] To address the problem of not being able to process irregular materials, a multi-specification storage mechanism 15 was designed. The storage mechanism 15 includes a housing 151, a rocker structure 152, a first movable plate 153, and a second movable plate 154. The rocker structure 152 has a threaded shaft, and two first movable plates 153 are connected to the threaded shaft. The housing 151 is provided with a sliding groove. Both ends of each first movable plate 153 can pass through the sliding groove and can move along the sliding groove under the action of the rocker structure. The first movable plates 153 are provided with U-shaped grooves with open tops spaced apart. The second movable plates 154 can be inserted into the U-shaped grooves. The distance between two adjacent second movable plates 154 can be adjusted by changing the placement of the U-shaped grooves in different positions.

[0101] The threaded shaft includes a first threaded portion and a second threaded portion, with the threads on the first threaded portion and the second threaded portion having opposite directions. A first movable plate 153 is disposed on the first threaded portion, and another first movable plate 153 is disposed on the second threaded portion. By rotating the rocker arm structure, the two first movable plates 153 can move synchronously toward or away from each other, thereby adjusting the distance between the two first movable plates 153.

[0102] Based on the shape of the object, the second movable plate 154 is moved so that the spacing between each second movable plate 154 is close to the length of the material. The rocker arm structure 152 is rocked to move the first movable plate 153 so that the width between the two plates is close to the width of the material. The material is placed in the hopper formed by the first movable plate 153 and the second movable plate 154. Each piece of material is placed in the hopper and gradually stacked until it is close to the top of the hopper. Each time the pushing mechanism 18 pushes out, the material falls down once due to its weight, until it is completely pushed out by the pushing mechanism 18.

[0103] This storage mechanism 15 can adapt to the storage of many different types, specifications, and shapes of materials by adjusting the first movable plate 153 and the second movable plate 154, such as shiitake mushrooms, bread slices, or fish balls, thus solving the problem of needing a lot of manual skewering on a larger scale.

[0104] The single-skewer and double-skewer skewer devices provided by this invention can be used simultaneously or individually, depending on actual needs. They can skewer both small square-shaped materials (such as beef skewers and lamb skewers) and round-shaped materials (such as meatball skewers), thus having a wider range of applications.

[0105] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
