Description

Technical Field

[0001] This utility model relates to the field of thousand-layer tofu processing technology, specifically to a thousand-layer tofu stringing device. Background Technology

[0002] Thousand-layer tofu is a sheet-shaped food product made primarily from soy protein, formed through high-temperature steaming and shaping. Compared to traditional tofu, it possesses unique elastic texture characteristics—maintaining moderate flexibility while also having excellent shape retention. This makes thousand-layer tofu less prone to breakage during grilling, frying, and other processing, making it particularly suitable as a raw material for ready-to-eat skewers.

[0003] However, this elasticity presents a unique technical challenge in mechanical skewering: when using the conventional parallel skewering method (i.e., piercing the tofu horizontally along the surface of the tofu), the elasticity of the tofu inside is relatively strong, and the elastic force generated during the skewering process can easily cause the skewering tool to deviate. Since the tofu is thin, the deviated skewer can easily pierce through the side of the tofu midway, and the tofu slices will fall off due to insufficient contact area. Utility Model Content

[0004] In view of this, the present invention provides a tofu skewering device, which can prevent tofu from coming out through the side of the tofu during the skewering process and improve the success rate of skewering.

[0005] To solve the above-mentioned technical problems, this utility model provides a tofu skewering device, including a support plate and a support assembly. The support assembly includes multiple support plates arranged in an array and fixedly connected to the top of the support plate. The support plates are arranged in pairs, and the top of the opposite surfaces of the two support plates in each pair are chamfered. The top of the support plate located at the center of each pair of support plates is fixedly connected to a suction cup, with the chamfer facing the adjacent suction cup. The suction end of the suction cup is set upward, and the top of the suction cup is lower than the top of the support plate. This can effectively prevent the tofu from breaking or being damaged by passing through the side of the tofu during the skewering process, thereby improving the success rate of skewering.

[0006] Each support block is fixedly connected to a guide cylinder, the axis of which coincides with the axis of the top arc surface of the support block, and the top of each guide cylinder is provided with an avoidance opening; thus guiding the skewering tool to accurately enter the tofu, improving the smoothness and efficiency of the skewering process.

[0007] Guide rings are fixedly connected to both ends of the guide cylinder. The diameter of the end of the guide ring closer to the adjacent guide cylinder is smaller than the diameter of the end farther away from the guide cylinder. This helps to accurately guide the tool during the threading process and ensures that the tool moves along the correct path.

[0008] The top of each support plate is provided with a clearance groove, which is arc-shaped; this is to prevent the tool from shifting and to ensure the accuracy of the threading process.

[0009] On the other side of the support plate is a threading assembly, which includes an electric slide rail placed on one side of the support plate, with an iron skewer inserted into one side of the slider of the electric slide rail; thus realizing the automated threading process and improving production efficiency.

[0010] The top of the electric slide rail is fixedly connected to multiple arrayed guide frames, and the middle of each iron skewer is slidably connected to the middle of the guide frame; this helps to limit and guide the movement of the iron skewer during the skewering process, improving the reliability of skewering.

[0011] Each suction cup has an air tube connected to its bottom, with the input end of the air tube connected to an external air source; this allows the suction cup to firmly adhere to the tofu.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. Thread the tofu along the curved sides instead of threading it parallel to the tofu. This curved threading method effectively prevents the tofu from coming out through the sides during the threading process, which can cause the tofu to break or be damaged, thus increasing the success rate of threading.

[0014] 2. The suction cup is located at the bottom and below the support plate. This provides a buffer space even if the bamboo skewers or metal skewers used for threading shift during the process, making it less likely for them to come into direct contact with the suction cup, thus effectively reducing damage to the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] like Figure 1-6 As shown: This embodiment provides a tofu skewer device, including a support plate 100 and a support assembly 200. The support assembly 200 includes multiple arrayed support plates 201 fixedly connected to the top of the support plate 100. The support plates 201 are in pairs. The top of the opposite surfaces of the two support plates 201 in each pair are provided with chamfers 202. The top of the support plate 100 located at the center of each pair of support plates 201 is fixedly connected with a suction cup 203. The chamfers 202 are all facing the adjacent suction cup 203. The suction ends of the suction cups 203 are all set upwards. The top of the suction cups 203 is lower than the top of the support plate 201.

[0028] When skewering, the tofu is placed on each suction cup 203 for adhesion. Simultaneously, the two edges of the tofu are supported by the support plate 201, causing the sides of the tofu to bend and curl upwards. This allows for skewering the tofu along the sides, rather than parallel to the surface. This bending skewering method effectively prevents the tofu from breaking or being damaged during skewering, increasing the success rate. The chamfered design 202 further guides the tofu to bend more smoothly, avoiding breakage caused by direct bending. After skewering, the suction cups 203 release the tofu, which, due to its elasticity, returns to a relatively flat state, facilitating subsequent processing or cooking. This method effectively reduces the number of defective products and material waste, making it suitable for large-scale production of thousand-layer tofu skewers.

[0029] In traditional devices for skewering tofu, the suction cup 203 is used to position the tofu during the skewering process. Since the suction cup 203 is parallel to the tofu, if the skewering tool shifts, its sharp end can easily collide with the suction cup 203, causing damage. However, in this device, the suction cup 203 is located at the bottom and below the support plate 201. This provides a buffer space even if the skewering tools (bamboo skewers, iron skewers 402, etc.) shift during the skewering process, making it less likely for them to directly contact the suction cup 203, effectively reducing damage to the device.

[0030] Guide component 300, etc. Figure 5 , 6 As shown,

[0031] The top of the support plate 100 is also provided with a plurality of guide components 300. The guide components 300 include a plurality of arrayed support blocks 301 fixedly connected to the top of the support plate 100. The support blocks 301 are all located between two adjacent sets of support plates 201. The top of the support block 301 is an inner arc surface.

[0032] During the threading process, the threading tool moves along the top inner arc surface of the support block 301, thereby maintaining the accuracy and stability of threading. In addition, due to the support of the inner arc surface of the support block 301, even if the threading tool deviates during the threading process, the support block 301 can provide a certain degree of support and guidance, reducing the degree of deviation and protecting the suction cup 203.

[0033] Guide cylinder 302 Figure 1 , 2 As shown in 3 and 6,

[0034] Each support block 301 has a guide cylinder 302 fixedly connected to its top. The axis of the guide cylinder 302 coincides with the axis of the top arc surface of the support block 301. Each guide cylinder 302 has an clearance opening 303 on its top.

[0035] During the skewering operation, the skewering tool (such as a bamboo skewer or an iron skewer 402) moves along the inside of the guide cylinder 302, providing a more enveloping guide for the skewering tool and ensuring the straightness of the tool. At the same time, since the top of the guide cylinder 302 has an avoidance opening 303, the skewering tool can be removed from the top of the guide cylinder 302 after skewering is completed.

[0036] 304 guide ring Figure 3 , 5 As shown in Figure 6,

[0037] Guide rings 304 are fixedly connected to both ends of the guide cylinder 302. The diameter of the end of the guide ring 304 closest to the adjacent guide cylinder 302 is smaller than the diameter of the end furthest from the guide cylinder 302. The axis of the guide ring 304 is set to coincide with the axis of the guide cylinder 302.

[0038] The guide ring 304 has a smaller diameter at the end closest to the adjacent guide cylinder 302, which guides the threading tool to accurately enter the guide cylinder 302 at the beginning of threading. As the threading tool goes deeper, the diameter of the guide ring 304 gradually decreases, eventually providing a more stable guide for the threading tool into the guide cylinder 302 and preventing it from deviating.

[0039] 305 clearance groove Figure 3 As shown,

[0040] The top of each support plate 201 is provided with a relief groove 305. The relief grooves 305 are all arc-shaped, and the axis of the relief groove 305 coincides with the axis of the guide cylinder 302.

[0041] The clearance groove 305 coincides with the skewering path of the skewering tool. The clearance groove 305 allows the skewer to be simply calibrated in one direction before entering the tofu placement area, thus preventing the skewering tool from deviating.

[0042] 400 threading components Figure 1 , 4 As shown,

[0043] On the other side of the support plate 100, a threading assembly 400 is provided. The threading assembly 400 includes an electric slide rail 401 placed on one side of the support plate 100. An iron skewer 402 is inserted into one side of the slider of the electric slide rail 401. The iron skewer 402 coincides with the axis of the guide cylinder 302.

[0044] At the start of the skewering operation, the electric slide rail 401 drives the slider to move along the slide rail, which in turn moves the iron skewers 402 along the axis of the guide cylinder 302 to skewer the tofu.

[0045] 400 threading components Figure 1 , 4 As shown,

[0046] The top of the electric slide rail 401 is fixedly connected to multiple arrayed guide frames 403, and the middle of the iron sticks 402 are all slidably connected to the middle of the guide frames 403.

[0047] During the threading process, the iron skewer 402 is constantly restricted and guided by the guide frame 403, preventing the iron skewer 402 from shifting or shaking. At the same time, the sliding connection method also reduces the friction between the iron skewer 402 and the guide frame 403, improving the smoothness of the threading process.

[0048] Trachea 101 Figure 1 , 2 As shown,

[0049] The bottom of each suction cup 203 is connected to an air tube 101, and the input end of the air tube 101 is connected to an external air source.

[0050] Before the skewering process begins, an external air source supplies compressed air to the suction cup 203 through the air pipe 101, causing the suction cup 203 to be in an adsorption state. When the tofu is placed on the suction cup 203, the adsorption force of the suction cup 203 can firmly fix the tofu, ensuring that the tofu will not move or fall off during the skewering process.

[0051] Once the tofu is skewered, the air pressure inside the suction cup 203 can be quickly reduced by controlling the external air source, causing the suction cup 203 to release the tofu. Due to the tofu's own elasticity, it will be released from the suction cup 203 and return to a relatively flat state, making it easier for subsequent processing or cooking.

[0052] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
