[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] See Figure 1 This application provides a fermented soybean paste loading device, comprising: a traveling track 1, located on both sides of a fermented soybean paste stacking area, wherein fermented soybean paste 2 are evenly distributed in the stacking area; a traveling support 3 and a drive assembly, wherein the drive assembly drives the traveling support 3 to move along the traveling track 1 above the fermented soybean paste 2; a cover opening and closing assembly 4, wherein multiple cover opening and closing assemblies 4 are disposed on the traveling support 3 and are used to open and close the sealing covers 21 of the fermented soybean paste 2 located in the same row; a hopper 5, disposed on the traveling support 3, for storing fermented soybean paste; a discharge assembly 6, disposed on the traveling support 3, connected to the hopper 5, wherein the discharge end of the discharge assembly 6 can deliver fermented soybean paste to the fermented soybean paste 2 located in the same row; and a control module, wherein the drive assembly, cover opening and closing assemblies 4, and discharge assembly 6 are all connected to the control module via signal connections.

[0045] In other words, two walking tracks 1 are laid on both sides of the soy sauce vat stacking area, providing a stable moving path for the walking support 3. More specifically, this ensures that the walking support 3 covers all the soy sauce vats 2.

[0046] The sauce vats 2 are evenly distributed in the stacking area, and each sauce vat is equipped with a sealing lid 21 to maintain the hygiene and quality of the sauce mash.

[0047] The arrangement and spacing of the sauce tanks 2 must match the design of the walking support and the opening and closing assembly to ensure smooth operation. More specifically, this application has three sauce tanks 2 in each row.

[0048] The drive assembly is responsible for driving the walking bracket 3 to move precisely along the walking track 1, ensuring that the device can reach the top of the soy sauce vat.

[0049] Three cover-opening components 4 are arranged side by side along the width of the traveling bracket 3, and each cover-opening component 4 is equipped with an opening and closing mechanism for the sauce vat sealing cover.

[0050] The hopper 5 is mounted on the traveling support 3 and is used to store the fermented sauce to be added.

[0051] The discharge component 6 is connected to the hopper 5 and is responsible for conveying the mash from the hopper 5 to the sauce vat 2.

[0052] The working principle is as follows:

[0053] The control module controls the drive component to move the walking bracket 3 along the walking track 1, so that the walking bracket 3 reaches above the target soy sauce tank 2.

[0054] Under the instruction of the control module, the cover opening assembly 4 simultaneously or individually opens the sealing cover 21 of the target sauce tank 2 located in the same row.

[0055] Drive the walking bracket 3 so that the discharge end of the discharge component 6 is above the sauce tank 2 with the sealing cover 21 open. Control the discharge component 6 to transport the sauce mash in the hopper 5 to the target sauce tank 2. The discharge end of the discharge component 6 can control the amount of sauce mash transported.

[0056] After the fermented sauce is delivered, the drive assembly drives the walking bracket 3 to move so that the cover opening and closing assembly 4 is positioned above the fermented sauce tank 2 after the fermented sauce has been added. Then, the cover opening and closing assembly 4 is controlled to move again to cover the sealing cover 21 on the fermented sauce tank 2.

[0057] Repeat the above steps to add mash to the next row of sauce vats 2 until all sauce vats 2 have completed the process of adding mash.

[0058] In summary, the soy sauce mash feeding device provided in this application greatly shortens the time for raw materials to be fed into the vat, improves overall production efficiency, reduces the labor intensity of workers, improves the working environment, and avoids the pollution risk caused by manual operation. It ensures the hygiene and safety of raw materials during transportation and feeding into the vat, achieves precise feeding of soy sauce mash, and helps maintain the quality consistency of each batch of soy sauce.

[0059] Based on the above embodiments, see Figure 2 The walking support 3 includes side plates 31 on both sides and a walking support plate 32 located at the top of the side plates 31. The driving component includes a walking wheel 33 and a drive motor. The walking wheel 33 is located at the bottom of the side plate 31, and the drive motor is located on the side plate 31. The drive motor can drive the walking wheel 33 to rotate.

[0060] Specifically, the traveling wheels 33 are located at the bottom of the side plate 31, and the traveling wheels 33 should be adapted to the shape and material of the traveling track to ensure smooth and low-noise movement.

[0061] The number and layout of the traveling wheels 33 should be determined according to the weight and size of the traveling bracket to ensure sufficient support and stability. Specifically, the number of traveling wheels 33 at the bottom of a single side plate 31 is three.

[0062] The drive motor is mounted on the side plate 31 and is used to drive the walking wheel 33 to rotate; the selection of the drive motor ensures that the walking bracket 3 can move smoothly and quickly along the walking track 1.

[0063] The drive motor is also equipped with a reducer or transmission mechanism to provide the required speed and torque output.

[0064] When the control module issues a movement command, the drive motor starts working, causing the walking wheel 33 to roll on the walking track 1. The walking bracket 3 moves along the walking track until it reaches the top of the target soy sauce tank. Specifically, the control module can control the rotation direction and rotation speed of the walking wheel 33.

[0065] Based on the above embodiments, see Figure 3 The hopper 5 is mounted on the upper end of the walking support plate 32 via support legs 51. The top of the hopper 5 is equipped with a horizontally sliding hopper cover, which controls the opening and closing of the feed inlet of the hopper 5 through the horizontal sliding action of the hopper cover. The top of the hopper 5 is equipped with a telescopic cylinder, and the telescopic end of the telescopic cylinder is fixedly connected to the hopper cover.

[0066] Specifically, the hopper 5 is securely mounted on the upper end of the walking support plate 32 via support legs 51. The top of the hopper 5 is equipped with a horizontally sliding hopper cover, which is used to control the opening and closing of the hopper inlet. The horizontal sliding action of the hopper cover can be achieved by the following mechanisms, such as slide rails and sliders. It should be ensured that the hopper cover can slide smoothly and accurately to achieve the opening and closing of the inlet.

[0067] A telescopic cylinder is fixedly installed on the top of the hopper 5 to control the horizontal sliding action of the hopper cover. The telescopic end of the telescopic cylinder is fixedly connected to the hopper cover. When the telescopic cylinder works, it will push or pull the hopper cover to slide horizontally along the preset track.

[0068] The telescopic cylinder establishes a signal connection with the control module of this application, so that the movement of the telescopic cylinder (such as extension and retraction) can be controlled by the control module.

[0069] Based on the above embodiments, see Figure 4 The discharge assembly 6 includes a pump body 61. The input end of the pump body 61 is connected to the bottom discharge port of the hopper 5. The output end of the pump body 61 is connected to a branch pipe 62. Multiple output pipes 63 of the branch pipe 62 can be located above each row of sauce tanks 2. Each output pipe 63 is equipped with a solenoid valve 64. The solenoid valve 64 establishes a signal connection with the control module.

[0070] In other words, the pump body 61 is located below the hopper 5, and its input end is closely connected to the bottom outlet of the hopper 5. Its function is: the pump body 61 serves as a power source, responsible for drawing out the mash from the hopper 5 and pressurizing and transporting it to the subsequent branch pipe 62.

[0071] Branch pipe 62 extends from the output end of pump body 61 to correspond to different output pipes 63. Thus, the branch pipe 62 of this application plays the role of distributing and transmitting soy sauce mash, and evenly distributing the soy sauce mash output by pump body 61 to each output pipe 63. Each output pipe 63 is located above each row of soy sauce tanks 2.

[0072] Each output pipe 63 is equipped with a solenoid valve 64, which is used to control the opening and closing of the output pipe 63. The solenoid valve 64 establishes a signal connection with the control module, which can realize remote control.

[0073] Based on the above embodiments, see Figure 5 The cover opening and closing assembly 4 includes a fixed plate 41, which is fixed on the walking support plate 32; a lifting mechanism, which is located on one side of the fixed plate 41, and its output end is detachably connected to the gripping mechanism frame 42. The lifting mechanism can drive the gripping mechanism frame 42 to move up and down in the vertical direction. The walking support plate 32 is provided with a channel for the gripping mechanism frame 42 to pass through. The bottom four corners of the gripping mechanism frame 42 are provided with gripping mechanisms, and the four gripping mechanisms can correspondingly clamp the edges of the sealing cover 21.

[0074] In other words, when it is necessary to open the sealing cover 21 of the sauce vat, the lifting mechanism is activated, driving the gripping mechanism frame 42 and its gripping mechanism to move vertically downwards until the gripping mechanism clamps the edge of the sealing cover 21. Then, the lifting mechanism continues to drive the gripping mechanism frame 42 and its gripping mechanism to move upwards, removing the sealing cover 21 from the sauce vat. When it is necessary to close the sauce vat, the lifting mechanism is activated again, driving the gripping mechanism frame 42 and its gripping mechanism to move downwards, accurately placing the sealing cover 21 on the sauce vat.

[0075] Based on the above embodiments, the lifting mechanism includes a driving member 43, which is fixedly mounted on the bottom of the fixed plate 41; and a moving block 44, whose bottom is fixedly connected to the telescopic end of the driving member 43, and whose two sides are slidably connected to the side walls of the fixed plate 41. The inner sides of the two side walls are provided with sliding grooves along the height direction, and the two sides of the moving block 44 are provided with pulleys that slide in cooperation with the sliding grooves.

[0076] Specifically, the drive component 43 is fixed to the bottom of the fixed plate 41 and can be an electric cylinder.

[0077] When the telescopic end of the drive member 43 extends, it pushes the moving block 44 upward along the slide groove and pulley combination structure of the fixed plate 41. The sliding connection ensures the precise vertical movement of the moving block 44. Conversely, when the telescopic end of the drive member 43 retracts, it pulls the moving block 44 downward along the same path. The rolling of the pulley within the slide groove not only reduces frictional resistance but also improves the smoothness and accuracy of the lifting motion.

[0078] Based on the above embodiments, the gripping mechanism frame 42 is detachably connected to the moving block 44 via the connecting plate 45. The gripping mechanism frame 42 is located at the bottom of the connecting plate 45, and a square frame 46 is provided at the bottom of the gripping mechanism frame 42. The size of the square frame 46 is larger than the size of the sealing cover 21.

[0079] Specifically, when the drive component 43 of the lifting mechanism extends or retracts, it pushes the moving block 44 to move up and down. Since the moving block 44 is detachably connected to the gripping mechanism frame 42 via the connecting plate 45, the gripping mechanism frame 42 and the gripping mechanism on it will also move up and down accordingly. Because the size of the square frame 46 is designed to be larger than the size of the sealing cover 21, it is ensured that when the gripping mechanism clamps the sealing cover 21, the square frame 46 can completely cover the sealing cover 21 and provide sufficient space for the gripping mechanism to perform the clamping operation.

[0080] Based on the above embodiments, the gripping mechanism includes a connecting frame 47 connected to the bottom corner of the square frame 46; a telescopic member 48 connected to the connecting frame 47, the output end of the telescopic member 48 being connected to an arc-shaped clamping plate 49, the telescopic member 48 being able to drive the arc-shaped clamping plate 49 to move towards the center of the square frame 46, and the arc-shaped clamping plate 49 being able to fit against the outer peripheral surface of the sealing cover 21.

[0081] In other words, the telescopic component 48 can be an electric cylinder connected to the connecting frame 47. The output end of the telescopic component 48 is connected to the arc-shaped clamp 49 and is used to drive the arc-shaped clamp 49 to move. Through its telescopic action, the telescopic component 48 can drive the arc-shaped clamp 49 to move towards the center of the square frame 46 or away from the center.

[0082] The curved clamp 49 is designed in an arc shape to better fit the outer circumferential surface of the sealing cap 21. One end of the curved clamp 49 is connected to the output end of the telescopic member 48, while the other end is designed as a free end for contacting the sealing cap 21 and applying clamping force. When the telescopic member 48 drives the curved clamp 49 to move towards the center of the square frame 46, the curved clamp 49 will fit tightly against the outer circumferential surface of the sealing cap 21, thereby clamping the sealing cap. Conversely, when the telescopic member 48 retracts, the curved clamp 49 will move away from the center of the square frame 46, releasing the clamping force on the sealing cap.

[0083] Working principle: Driven by the lifting mechanism, the gripping mechanism frame 42 and its gripping mechanism move above the sealing cover 21. Then, the telescopic component 48 starts working, driving the arc-shaped clamping plate 49 to move towards the center of the square frame 46 until the arc-shaped clamping plate 49 is tightly attached to the outer circumferential surface of the sealing cover 21. At this point, the gripping mechanism has successfully clamped the sealing cover 21. When it is necessary to release the sealing cover 21, the telescopic component 48 will work in the opposite direction, driving the arc-shaped clamping plate 49 away from the center of the square frame 46, thereby releasing the clamping of the sealing cover 21.

[0084] Specifically, the control module of this application operates in two modes: manual and automatic, thereby controlling the actions of the drive component, the cover opening and closing component 4, and the material discharge component 6. The control module of this application is a programmable logic controller (PLC).

[0085] In other words, in manual operation mode, the operator can directly input commands to the control module through the buttons and knobs on the control panel, which will control the start, stop, acceleration, deceleration, and steering of the drive components (such as motors), as well as the lifting, clamping, and releasing of the cover opening and closing components 4 (including lifting mechanism and gripping mechanism), and the discharging and stopping of the material discharging components 6.

[0086] In automatic operation mode, the control module will automatically control the actions of the drive component, the cover opening and closing component 4 and the discharge component 6 according to the preset program or instruction set. The program or instruction set contains detailed information such as the action sequence, time interval and motion parameters of each component.

[0087] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0088] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
