Description

Technical Field

[0001] This invention relates to the field of soybean product preparation technology, specifically to a soybean stick machine capable of continuous and automatic extraction. Background Technology

[0002] Bean sticks, also known as bean tendons, bean stalks, or bean shoots, are a unique bean product from Sichuan, Yunnan, Guizhou, and Chongqing. They are a high-protein byproduct extracted from soybeans, rich in nutrients (containing approximately 40% protein and 20% fat) and have a delicious flavor. Bean sticks are made by soaking selected soybeans, grinding them, boiling them, and filtering the resulting soy milk. The soy milk is then boiled in a corner of a pot over high heat, blown about until a skin forms, and then rolled up with a bamboo stick and dried. Because of their shape, resembling a thin bamboo stick, they are called "bean sticks" by the locals.

[0003] With the development of industrialization, the processing of bean curd sticks is becoming increasingly automated. For example, the invention patent CN105875854A discloses a bean curd stick rolling machine, which includes a frame and a pot body set on the frame. The pot body is equipped with a horizontal frame and bean curd stick rollers for rolling bean curd sheets. The frame is also equipped with a bracket for placing the bean curd stick rollers. A bean curd stick conveying device is set between the bracket and the pot body for automatically clamping and transferring the bean curd stick rollers between the two. This invention patent, by setting up a bean curd sheet lifting device, a clamping device, a rotating device, and a conveying device, can automatically clamp, lift, rotate, roll, unroll, and transport bean curd sheets. It not only solves the problems of low efficiency, high labor costs, and poor rolling quality of traditional manual rolling, but also increases the rolling speed, produces bean curd sheets with uniform thickness and less surface slurry, thus improving the quality and taste of the bean curd sticks.

[0004] However, the aforementioned rolling machine uses a single bean stick roller to clamp and roll the bean curd sheets when rolling them. Each bean stick roller can only rotate and extract one bean curd sheet at a time. After extraction, the bean stick roller that has rolled the bean curd sheets is transported by a conveying device. This makes it impossible to roll continuously without interruption. It requires waiting for the bean curd sheets to solidify on the pot surface, which results in a long waiting time and affects processing efficiency. Therefore, a bean stick machine that can continuously and automatically extract bean curd sheets is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bean stick machine capable of continuous automatic extraction, which has the advantages of high continuous production efficiency and solves the problem of poor efficiency caused by inconvenience in continuous production.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bean stick machine capable of continuous automatic extraction, comprising a frame and a chain conveyor mounted on the frame, wherein several trays are slidably placed above the frame and the trays are fixed to the chains on the chain conveyor, and an extraction rod for extracting bean skins is placed on the trays, and a soy milk cooking pot is placed in the lower middle part of the frame.

[0008] The rear translation component is capable of gripping and moving the blank No. 1 and No. 2 extraction rods horizontally on the mounting platform.

[0009] A front rotating clamp and a rear pre-clamp are respectively installed below the mounting platform;

[0010] Front rotating clamp: It can receive and clamp the blank No. 1 extraction rod, and then it can be lowered into the soy milk liquid along the vertical horizontal plane to stick the soy skin on the surface of the soy milk and rotate to roll up the soy skin.

[0011] Rear pre-clamp: capable of receiving and clamping the No. 2 extraction rod conveyed by the rear translation component;

[0012] Forward translation component: After moving horizontally on the mounting platform to near the front rotating clamp, it clamps the No. 1 extraction rod of the rolled bean curd skin on the front rotating clamp to the rear preparation clamp and cuts the rolled bean curd skin, so that the bean curd skin on the No. 1 extraction rod and the continuous bean curd skin on the pot surface are completely separated. After cutting, the continuous bean curd skin on the pot surface falls and sticks to the No. 2 extraction rod on the rear preparation clamp. The forward translation component moves the No. 2 extraction rod on the rear preparation clamp forward to the front rotating clamp. Then the front rotating clamp rotates and rolls again to achieve continuous winding.

[0013] The rear translation component includes a first slide mounted on the mounting platform, a support frame fixedly connected to the lower part of the first slide, a first lifting cylinder fixedly mounted on both the left and right ends of the support frame, and a first pneumatic gripper fixedly mounted on the output end of the first lifting cylinder.

A threaded rod that is rotatably connected to the output shaft of the servo motor is fixedly connected to the inner side of the connecting plate. A threaded block is threadedly connected to the threaded rod. An air knife is fixedly installed on the threaded block.

[0015] The front rotating clamp includes two first columns symmetrically installed below the mounting platform. The first columns are located between the first slide and the second slide. Each first column is equipped with a third lifting cylinder on the side near the first slide. A first clamping cylinder is fixedly installed at the output end of each third lifting cylinder. An L-shaped support plate is fixedly connected to the output end of each first clamping cylinder. A rotating chuck is rotatably installed at the lower end of each support plate. A rotating motor is also fixedly installed on the inner side of one support plate. The rotating chuck on the same side of the support plate is fixedly connected to the output shaft of the rotating motor with a second bevel gear that meshes with each other.

[0016] The rear pre-clamp includes two second columns that are symmetrically fixedly connected below the mounting platform. The second columns are located between the first column and the first slide. A second clamping cylinder is fixedly installed on the side of the second column closer to the first column, and a clamping plate is fixedly connected to the output end of the second clamping cylinder.

[0017] Furthermore, racks are fixedly installed on both the left and right sides of the upper surface of the mounting platform, and the first and second slides are each provided with a drive assembly for driving them to move horizontally on the mounting platform.

[0018] The drive assembly includes two drive shafts, which are rotatably mounted on the inner sides of the first and second slides respectively. A drive motor is fixedly connected to one side of each of the first and second slides. A first bevel gear that meshes with each other is fixedly connected to the output shaft of the drive motor and the drive shaft. Drive gears are fixedly connected to both ends of the drive shaft, and the drive gears mesh with a rack.

[0019] Furthermore, sliders are fixedly connected to the lower surfaces of the left and right ends of the first and second slides, and guide rails are installed on the left and right sides of the upper surface of the mounting platform, with the sliders slidably connected to the guide rails.

[0020] Furthermore, the lower end of the clamping plate is L-shaped, and the opposite side of the L-end of the two clamping plates is convex. The specifications of the convex end of the clamping plate are the same as the specifications of the clamping end of the rotating chuck.

[0021] Furthermore, the frame is provided with a limiting component for supporting the limiting tray;

[0022] The limiting components include several limiting cylinders, which are symmetrically fixed in pairs above the frame. The output end of each limiting cylinder is fixedly connected to a stop block, and the limiting cylinders are symmetrically distributed in pairs.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This bean stick machine, capable of continuous automatic extraction, utilizes a combination of a rear translation component, a front translation component, a front rotating clamp, and a rear pre-clamp. This allows one extraction rod to rotate and rewind while the other extraction rod is clamped and prepared. This coordinated operation between the two extraction rods enables the bean skin to switch between adhering objects and to be cut off, thus continuously rewinding and extracting the bean skin, thereby improving the production efficiency of bean sticks.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 and 2 In this embodiment, a bean stick machine capable of continuous automatic extraction includes a frame 1 and a chain conveyor 2 installed on the frame 1. Several trays 3 are slidably placed on the top of the frame 1, and the trays 3 are fixed to the chain on the chain conveyor 2. An extraction rod for extracting bean skins is placed on the trays 3, and a soy milk cooking pot is placed in the lower middle part of the frame 1.

[0035] A mounting platform 4 is provided above the center of the rack 1, and a rear translation component 5 and a front translation component 6 are slidably mounted on the mounting platform 4.

[0036] Rear translation component 5: capable of gripping blank extraction rods 1 and 2 and moving them horizontally on mounting platform 4;

[0037] The front rotating clamp 7 and the rear preparatory clamp 8 are respectively installed below the mounting platform 4;

[0038] Front rotating clamp 7: It can receive and clamp the blank No. 1 extraction rod, and then it can be lowered into the soy milk liquid along the vertical horizontal plane to stick the soy skin on the surface of the soy milk and rotate and roll up the soy skin.

[0039] Rear pre-clamp 8: capable of receiving and clamping the No. 2 extraction rod conveyed by the rear translation assembly 5;

[0040] Forward translation component 6: After moving horizontally on the mounting platform 4 to near the front rotating clamp 7, it clamps the first extraction rod of the rolled-up bean curd skin on the front rotating clamp 7 to the rear preparatory clamp 8 and cuts the rolled-up bean curd skin, so that the bean curd skin on the first extraction rod and the continuous bean curd skin on the pot surface are completely separated. After cutting, the continuous bean curd skin on the pot surface falls and sticks to the second extraction rod on the rear preparatory clamp 8. The forward translation component 6 moves the second extraction rod on the rear preparatory clamp 8 forward to the front rotating clamp 7. Then the front rotating clamp 7 rotates and rolls again to achieve continuous winding.

[0041] In this embodiment, the cooperation of the rear translation component 5, the front translation component 6, the front rotating clamp 7, and the rear preparatory clamp 8 allows one extraction rod to be rotated and wound while the other extraction rod is clamped and prepared. This cooperative operation of the two extraction rods enables the bean skin to switch between the two extraction rods and to cut the bean skin itself, thereby continuously winding and extracting the bean skin and improving the production efficiency of bean sticks.

[0042] It should be noted that the soy milk cooking pot has an extended pot surface, and an air-cooling pipe is installed on the pot surface to continuously blow air onto the pot surface, causing the condensed soy skin to continuously form on the surface of the soy milk. This skin then flows towards the front rotating clamp 7 directly below the pot surface, following the direction of the air-cooling pipe and the direction of the liquid flow, until it reaches the end of the pot surface.

[0043] Among them, the frame 1 is equipped with a limiting component for supporting the limiting tray 3;

[0044] The limiting components include several limiting cylinders 10, which are symmetrically fixed in pairs above the frame 1. The output end of the limiting cylinder 10 is fixedly connected to a stop block 11. The limiting cylinders 10 are symmetrically distributed in pairs. The stop block 11 pushed by the limiting cylinder 10 blocks the pallet 3 conveyed by the chain conveyor 2 to stop and limit it. The number of limiting cylinders 10 is set according to the number of pallets 3. For example, when there are three pallets 3, there are three sets of limiting cylinders 10.

[0045] Please see Figure 1 and 3 In this embodiment, the rear translation component 5 includes a first slide 51 that is slidably installed above the mounting platform 4. A support frame 52 is fixedly connected to the lower part of the first slide 51. A first lifting cylinder 53 is fixedly installed at both the left and right ends of the support frame 52, and a first pneumatic gripper 54 is fixedly installed at the output end of the first lifting cylinder 53.

[0046] In this embodiment, by activating the first lifting cylinder 53 to lower the first pneumatic gripper 54 and the first slide 51 that can slide horizontally on the mounting platform 4, the extraction rod placed on the tray 3 can be clamped and fixed, and then horizontally transported.

[0047] Please see Figure 1 and 4In this embodiment, the forward translation component 6 includes a second slide 61 slidably connected to the mounting platform 4 and located in front of the first slide 51. A connecting frame 62 is fixedly connected below the second slide 61. A mounting plate 63 is fixedly connected to the lower end of the connecting frame 62. A second lifting cylinder 64 is fixedly connected to both the left and right ends of the mounting plate 63. A second pneumatic gripper 65 is fixedly installed at the output end of the second lifting cylinder 64. A U-shaped connecting plate 66 is fixedly connected to the side of the mounting plate 63 near the support frame 52. A servo motor 67 is fixedly installed at one end of the connecting plate 66. A threaded rod 69 is rotatably connected to the output shaft of the servo motor 67. A threaded block 68 is threadedly connected to the threaded rod 69. An air knife 610 is fixedly installed on the threaded block 68. The air inlet of the air knife 610 is connected to the air outlet of the high-pressure blower, so that the high-pressure blower delivers high-pressure airflow to the air knife 610 to cut the bean curd skin.

[0048] In this embodiment, after the servo motor 67 is started to drive the threaded rod 69 to rotate, the air knife 610 on the threaded block 68 can move laterally along the horizontal plane to cut the rolled bean curd skin. After the cutting action is completed, since the second slide 61 can also slide horizontally on the mounting platform 4, the second slide 61 can be driven to move the second pneumatic gripper 65 to the top of the rolled extraction rod. Then, the second lifting cylinder 64 lowers the second pneumatic gripper 65 to clamp the rolled extraction rod and moves it to the empty position of the extraction rod on the tray.

[0049] It should be noted that racks 9 are fixedly installed on both the left and right sides of the upper surface of the mounting platform 4, and drive components for driving them to move horizontally on the mounting platform 4 are provided on the first slide 51 and the second slide 61.

[0050] The drive assembly includes two drive shafts 57, which are rotatably mounted inside the first slide 51 and the second slide 61, respectively. A drive motor 55 is fixedly connected to one side of each of the first slide 51 and the second slide 61. A first bevel gear 56 that meshes with each other is fixedly connected to the output shaft of the drive motor 55 and the drive shaft 57. Drive gears 58 are fixedly connected to both ends of the drive shaft 57, and the drive gears 58 mesh with the rack 9. After the start of the drive motor 55 drives the drive shaft 57 to rotate through the first bevel gear 56, the drive gears 58 at both ends of the drive shaft 57, in conjunction with the rack 9, can drive the first slide 51 and the second slide 61 to slide laterally above the mounting platform 4 along a horizontal plane.

[0051] In addition, sliders 59 are fixedly connected to the lower surfaces of the left and right ends of the first slide 51 and the second slide 61. Guide rails are installed on the left and right sides of the upper surface of the mounting platform 4, and the sliders 59 are slidably connected to the guide rails. The sliders 59 sliding on the guide rails support the first slide 51 and the second slide 61 respectively, so as to improve the stability of the first slide 51 and the second slide 61 during the sliding process.

[0052] Please see Figure 1 and 5 -7. In this embodiment, the front rotating clamp 7 includes two first columns 71 symmetrically installed below the mounting platform 4. The first columns 71 are located between the first slide 51 and the second slide 61. Each first column 71 is equipped with a third lifting cylinder 72 on the side near the first slide 51. Each third lifting cylinder 72 is fixedly equipped with a first clamping cylinder 73 at its output end. Each first clamping cylinder 73 is fixedly connected to an L-shaped support plate 74 at its output end. Each support plate 74 is rotatably equipped with a rotating chuck 76 at its lower end. A rotary motor 75 is also fixedly installed on the inner side of one side of the support plate 74. The end of the rotating chuck 76 on the same side of the support plate 74 near the rotary motor 75 is fixedly connected to the output shaft of the rotary motor 75 with a second bevel gear 77 that meshes with each other.

[0053] The rear pre-clamping fixture 8 includes two second columns 81 that are symmetrically fixedly connected below the mounting platform 4. The second columns 81 are located between the first column 71 and the first slide 51. A second clamping cylinder 82 is fixedly installed on the side of the second column 81 closest to the first column 71, and a clamping plate 83 is fixedly connected to the output end of the second clamping cylinder 82.

[0054] In this embodiment, when the first clamping cylinder 73 is activated, it drives the rotating clamps 76 on both sides to move toward the opposite side, and clamps and fixes the extraction rod that has moved to the space between the rotating clamps 76 on both sides. The activated third lifting cylinder 72 can then reciprocate to lift and fix the extraction rod into the soy milk cooking pot. The extraction rod is used to adhere and lift the cooled bean curd skin, and the rotating motor 75 drives the extraction rod to rotate, thus rolling the bean curd skin.

[0055] When the second clamping cylinder 82 is activated, it can take the subsequent extraction rod held by the first pneumatic gripper 54 and clamp and fix it through its clamping end, so as to prepare the extraction rod.

[0056] It should be noted that the lower end of the clamping plate 83 is L-shaped, and the opposite side of the L end of both clamping plates 83 is convex. The specifications of the convex end of the clamping plate 83 are the same as the specifications of the clamping end of the rotating chuck 76, so that both the clamping end of the clamping plate 83 and the rotating chuck 76 can stably clamp and fix the extraction rod.

[0057] The working principle of the above embodiments is as follows:

[0058] Start the first automatic cycle:

[0059] After the blank extraction rod is placed on the tray 3 and moved horizontally behind the rear preparation fixture 8 under the conveyor of the chain conveyor 2, the chain conveyor 2 can be stopped and the limit cylinder 10 can be activated to push the stop block 11 to block the tray 3.

[0060] By activating the first lifting cylinder 53 to lower the first pneumatic gripper 54 and the first slide 51 that can slide horizontally on the mounting platform 4, the extraction rod placed on the tray 3 directly behind the rear translation component 5 can be clamped and fixed, and then transported horizontally.

[0061] When the first pneumatic gripper 54 on the rear translation assembly 5 successively grips two blank extraction rods, which can be regarded as extraction rod number one and extraction rod number two, extraction rod number one is placed between the two rotating jaws 76 of the front rotating clamp 7, and the first clamping cylinder 73 is activated to drive the rotating jaws 76 on both sides to move towards the opposite side for clamping and fixing. Extraction rod number two is driven by the second clamping cylinder 82 activated on the rear preparatory clamp 8 to move the clamping plates 83 on both sides towards the opposite side for clamping and fixing.

[0062] After the front rotating clamp 7 receives and clamps the blank No. 1 extraction rod, the third lifting cylinder 72 can be activated to lower the blank No. 1 extraction rod into the soy milk liquid, and then move upward to reset. During this process, the extraction rod and the soy skin on the surface of the soy milk stick together. Under normal continuous operation, the up and down movement of the front rotating clamp 7 only needs to be performed once.

[0063] Then:

[0064] The starting rotary motor 75 drives the rotary chuck 76 and the first extraction rod to rotate via the second bevel gear 77, so that the bean curd skin is rolled onto the first extraction rod. After it is rolled to a suitable thickness, the rear translation component 5 clamps the first extraction rod on the front rotary clamp 7, moves it upward and backward, and moves it to the rear upper part of the rear preparation clamp 8. Then the front translation component 6 moves backward to a suitable position in front of the rear translation component 5 and stops. The servo motor 67 on the front translation component 6 is started, which drives the air knife 610 to blow and cut the bean curd skin through the threaded block 68 and the threaded rod 69. This completely separates the bean curd skin on the first extraction rod on the front rotary clamp 7 from the continuous bean curd skin on the pot surface, and makes the second extraction rod on the rear preparation clamp 8 stick to the cut bean curd skin. The sticky bean curd skin is the continuous bean curd skin on the pot surface.

[0065] After the cutting action is completed, the rear translation component 5 clamps the rolled No. 1 extraction rod, moves it backward and places it in the empty extraction rod position on the tray 3, then clamps the adjacent blank No. 3 extraction rod and moves it forward, and finally places it between the two clamping plates 83 on both sides of the rear preparation clamp 8, and is fixed again by the clamping plates 83.

[0066] During the operation of the above-mentioned device, the front translation component 6 lowers the second pneumatic gripper 65 through the second lifting cylinder 64 to pick up the second extraction rod that is attached to the bean skin and located on the rear preparatory clamp 8, and moves it forward from the rear preparatory clamp 8 to the front rotating clamp 7, where it is fixed again by the rotating chuck 76.

[0067] The first automatic cycle ends, and the second cycle begins:

[0068] The front rotating clamp 7 then rotates and rolls the bean skin until it reaches a suitable thickness. The rear translation component 5 then clamps the extraction rod on the front rotating clamp 7, moves it upward and then backward, and moves it to the rear and above the rear preparation clamp 8. Immediately afterwards, the front translation component 6 moves backward to a suitable position in front of the rear translation component 5 and stops. The air knife on the front translation component 6 is activated to blow and cut the bean skin, so that the bean skin on the second extraction rod on the front rotating clamp 7 is completely separated from the continuous bean skin on the pot surface, and the third extraction rod on the rear preparation clamp 8 is stuck to the continuous bean skin on the pot surface.

[0069] The above automatic cycle continues until all the blank extraction rods on the rear tray 3 are used up. Then, the chain conveyor 2 is restarted to transport the tray 3 with blank extraction rods to directly below the mounting platform 4. All the rolled-up trays 3 are transported horizontally and moved to the working position behind the rear preparation clamp 8 to continue the next cycle of continuous bean curd skin extraction.

[0070] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
