Description

Technical Field

[0001] This invention relates to a fabric head, specifically a fabric head used in the process of brewing baijiu (Chinese liquor), and belongs to the field of automation equipment technology. Background Technology

[0002] In the baijiu brewing process, after the mash is prepared, it needs to be put into a still for steaming. This process requires the mash to be evenly and efficiently distributed into the still. Most distilleries use a feeding head that can only distribute the mash. The mash needs to be conveyed through a complex plate chain conveyor into the feeding head, which has problems such as complex process, large space occupation by the plate chain, high evaporation, high cost, and long time. Traditional distilleries generally use a plate chain conveyor system in conjunction with the feeding head to complete the distribution operation. This method has obvious drawbacks: First, the plate chain conveyor system has a complex structure and occupies a large space, resulting in a cramped equipment layout and low plant utilization. Second, the mash has a large exposed area and long exposure time during long-distance transportation, which can easily cause the evaporation of effective components such as alcohol, affecting the yield and quality of the liquor. Third, the traditional feeding head has a single function, which can only complete the distribution action. Grabbing the material requires a separate material grabbing device or manual assistance, making the entire feeding process cumbersome, time-consuming, labor-intensive, inefficient, and with high labor costs.

[0003] In existing technologies, such as the fabric feeding head disclosed in CN217855589U for powder application, multiple colorant cylinders and a quantitative feeding device are set up, and the output of each colorant is precisely controlled by a controller. Although this solves the accuracy problem of quantitative application of powdered materials to a certain extent, its overall structure still focuses on a single fabric feeding function, without integrating a material gripping mechanism. It cannot get rid of its dependence on the pre-conveying equipment, and its application scenarios are mainly for the application of decorative materials such as microcrystalline glass, which are not suitable for materials such as wine mash that have a certain viscosity and are prone to agglomeration. The existing technology suffers from mismatch and insufficient adaptability. For example, the rotatable ultrasonic cutting head disclosed in CN222313622U uses multiple drive mechanisms to coordinate and control the cutter's multi-angle and multi-directional displacement and rotation, aiming to reduce the number of repeated fabric feedings and improve cutting efficiency. This design focuses on the integration and optimization of the cutting process, but its technical approach concentrates on the cutting and positioning of two-dimensional fabrics, without addressing the integration of material gripping and fabric application functions. It also fails to meet the integrated operational requirements for gripping, transferring, and evenly applying loose solid materials (such as fermented mash) in three-dimensional space. Therefore, the existing technology lacks a dedicated fabric application head device that integrates gripping and fabric application functions, significantly simplifies the process, reduces space occupation, and minimizes material evaporation losses. This has become a key technical problem restricting the efficiency improvement and cost control of automated production lines in baijiu brewing. Based on this, this application proposes a fabric application head for use in the baijiu brewing process. Summary of the Invention

[0026] 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.

[0027] Example 1, as Figures 1 to 5As shown, a fabric feeder used in the brewing process of baijiu (Chinese liquor) includes a fabric feeder body 1, an electric cylinder connecting rod assembly 2, a belt assembly 3, a scraper 4, a dispersing electric roller 5, a brush assembly 6, and a connecting flange 7. The top of the fabric feeder body 1 is connected to the connecting flange 7 by bolts. The electric cylinder connecting rod assembly 2 is disposed on both sides of the fabric feeder body 1, and the electric cylinder connecting rod assembly 2 is rotatably connected to the pins on the fabric feeder body 1 and the belt assembly 3, respectively. The belt assembly 3 is rotatably connected to the bottom end of the fabric feeder body 1 by pins. The dispersing electric roller 5 is arranged laterally and fixed inside the cavity of the fabric feeder body 1, and the dispersing electric roller 5 is located above the belt assembly 3. The scraper 4 is bolted to the opening at the bottom end of the fabric feeder body 1. The brush assembly 6 is bolted to the belt assembly 3.

[0028] The fabric head body 1 has two modes: a spreading state and a gripping state. When the fabric head body 1 is in the spreading state, the belt assembly 3 is completely attached to the bottom of the opening of the fabric head body 1. When the fabric head body 1 is in the gripping state, the belt assembly 3 is separated from the bottom of the opening of the fabric head body 1.

[0029] The fabric head is connected to an external robotic arm via flange 7, enabling overall movement and positioning. The electric cylinder linkage assembly 2 controls the movement of the belt assembly 3, ensuring that the belt assembly 3 is in contact with the bottom of the opening when the fabric head body 1 is in the spreading state, guaranteeing smooth material transport. In the grabbing state, the belt assembly 3 separates from the bottom of the opening, facilitating material retrieval from the pile. A dispersing electric roller 5, located above the belt assembly 3, disperses the material to prevent clumping and ensure uniform fabric distribution. A scraper plate 4 removes residual material, keeping the surface clean, while a brush assembly 6 cleans the belt to prevent adhesion. This integrated design reduces equipment costs and improves production efficiency, making it suitable for automation scenarios such as liquor brewing.

[0030] Example 2: In addition to all the technical features in Example 1, this example also includes: the fabric head body 1 includes a fabric head frame 15. Shaft 11, shaft 2 12, shaft 3 13 and shaft 4 14 are welded to both sides of the frame of the fabric head frame 15. The frame of the fabric head frame 15 is connected to the belt assembly 3 through shaft 11 on both sides of the frame. The fabric head frame 15 enhances the overall rigidity and durability of the fabric head. The arrangement of shaft 11, shaft 2 12, shaft 3 13 and shaft 4 14 enables the electric cylinder connecting rod assembly 2 and the belt assembly 3 to rotate smoothly and achieve reliable state switching.

[0031] The electric cylinder connecting rod assembly 2 includes cylinder 1 21 and cylinder 2 28. A cylinder fixing bracket 22 is fixedly connected to the front end of the cylinder barrel of cylinder 1 21. A connecting rod 24 is rotatably connected to the front end of the piston rod of cylinder 1 21. The rear end of the cylinder barrel of cylinder 2 28 is rotatably connected to the middle part of the rod of connecting rod 24. A belt assembly fastening connecting rod 27 is rotatably connected to the front end of the piston rod of cylinder 2 28. The cylinder fixing bracket 22 is rotatably connected to shaft 3 13. The middle part of the rod of connecting rod 24 is also rotatably connected to shaft 2 12. The middle part of the belt assembly fastening connecting rod 27 is rotatably connected to shaft 4 14. The connecting rod mechanism is driven by the extension and retraction of the cylinders to control the attitude switching of the belt assembly 3. During the state transition, cylinder 1 21 and cylinder 2 28 coordinate their actions to drive connecting rod 24 and belt assembly fastening connecting rod 27 to rotate, thereby lifting and fastening the belt assembly 3, ensuring the smoothness and reliability of the state transition.

[0032] The piston rod of cylinder 21 is fixedly connected to cylinder connector 23, which is rotatably connected to connecting rod 24. The piston rod of cylinder 28 is fixedly connected to cylinder connector 29, which is rotatably connected to connecting rod 27 fastened to belt assembly. The connectors ensure that a rotatable connection can be achieved, allowing a certain degree of freedom between the cylinder and the connecting rod to adapt to angle changes during the movement and ensuring the efficiency of power transmission.

[0033] The movable front end of the first connecting rod 24 is provided with the second connecting rod 25. The docking part of the first connecting rod 24 and the second connecting rod 25 is rotatably connected by the connecting rod pin 26. The movable front end of the second connecting rod 25 is rotatably located on both sides of the belt assembly 3. The two-stage connecting rod design expands the range of motion, enabling the belt assembly 3 to achieve greater angle changes and better adapt to the requirements of material grabbing and spreading.

[0034] Example 3, in addition to all the technical features of Example 1, also includes: the belt assembly 3 includes a driven roller 31, a belt 33, a driving roller 34, and a belt assembly frame 38. The driven roller 31 and the driving roller 34 are rotatably connected to both ends of the belt assembly frame 38. The belt 33 is mounted on the drum body of the driven roller 31 and the driving roller 34. Shaft 5 37 and shaft 6 39 are fixedly connected to both sides of the belt assembly frame 38, and shaft 5 37 is rotatably connected to the movable front end of the connecting rod 25. When the fabric head body 1 is in the spreading state, shaft 6 39 is engaged with the belt assembly fastening link 27 limit buckle. The driven roller 31 and the driving roller 34 support the belt 33 to realize material conveying. The belt assembly frame 38 provides structural support. Shaft 5 37 is connected to link 2 25. When shaft 6 39 is in the spreading state, it is engaged with the belt assembly fastening link 27 to ensure that the belt assembly 3 is tightly fitted with the fabric head body 1 in the spreading state, preventing material leakage, ensuring the stable operation of the belt during the spreading process, and improving the spreading accuracy.

[0035] Side baffles 35 are fixedly connected to the upper sides of the two sides of the belt assembly frame 38. A rear baffle 32 is fixedly connected to the upper side of the frame of the belt assembly frame 38 that connects to the driven roller 31. Rotary connecting plates 36 are fixedly connected to the two sides of the frame of the belt assembly frame 38 that connects to the drive roller 34, and the rotary connecting plates 36 are rotatably connected to the shaft 11. The side baffles 35 prevent material from overflowing from the sides of the belt, and the rear baffle 32 prevents material from overflowing from the rear end. The rotary connecting plates 36 are connected to the shaft 11, allowing the belt assembly 3 to rotate around the shaft 11. The baffles ensure that the material will not scatter during the conveying process, improving the efficiency and quality of material distribution, reducing material waste, and maintaining a clean working environment. The rotary connecting plates 36 allow the belt assembly 3 to rotate smoothly when switching states.

[0036] Example 4, in addition to all the technical features included in Example 1, also includes: Figure 6 As shown, the fabric head body 1 is also equipped with multiple distance sensors, which are distributed around the opening of the fabric head body 1. These sensors are used to monitor the material height inside the fabric head in real time, calculate the material volume through the measured values, and realize real-time monitoring of the material quantity to optimize the material gripping and spreading process. During material gripping, the sensors detect whether the material is full to avoid overloading or underloading. During spreading, the sensors monitor the remaining material quantity to ensure continuous operation and prevent interruptions. The sensor data is fed back to the host computer to realize automated control, improve production efficiency and accuracy, reduce manual intervention, reduce errors, and make the fabric head more intelligent and adaptive, suitable for high-precision automated production lines.

[0037] Both the drive roller 34 and the dispersing electric roller 5 have built-in motors and reducers. The drive roller 34 and the dispersing electric roller 5 control their speed according to input commands and feed back actual data to the host computer. This enables speed control of the drive roller 34 and the dispersing electric roller 5, thereby adjusting the material flow rate and dispersing effect, ensuring stable and uniform output, automatically adjusting the roller speed according to the material flow rate, maintaining stable output, improving the quality of the fabric, and adapting to the needs of automated production.

[0038] The real-time material volume inside the hopper cavity can be calculated using a distance measuring sensor on the hopper. The specific calculation method is as follows: laser distance measurement 1-i first records the initial empty hopper value L1-L. N Record value L after the action is completed. i1 -L iE From this, the material surface height h can be obtained. i =(L iE -L1)*K i , (K i(As a fixed coefficient), the hopper cavity is fixed, with a fixed width of W. Based on the material accumulation and flow pattern and the connection of each measuring point, the surface height curve function h(x) of the material in the hopper cavity can be obtained. By integrating the surface height function over the material length, the cross-sectional area of ​​the material can be obtained. Based on the material width and cross-sectional area, the actual material volume V = W * ∫h(x) d can be calculated. x .

[0039] During the material feeding process, the material output flow rate and whether there is material surplus are obtained based on the real-time material volume change rate of the feeding hopper. When the material quantity is lower than the conveying requirement, a signal can be sent to the upper-level system to retrieve material again. Based on the material flow rate and feedback data (speed, current, torque, etc.) from the dispersing electric roller 5 and the driving roller 34, the roller running speed can be automatically controlled through PID technology to achieve a stable output.

[0040] The specific calculation is as follows: the required material is set to fall evenly at a rate of V. set The actual drop volume calculated using the volume measurement method is V. actual (t), its error:

[0041] e(t) = V set -V actual (t)

[0042] u(t)=Kp*e(t)+Ki*∫e(t)dt+Kd*de(t) / dt,

[0043] To ensure equipment stability, a speed limit R is set. max and R min This will also introduce the maximum calculated rotational speed u. max The final formula for calculating the control speed of the drum is:

[0044] RPM(t) = R min +(R max -R min )*(u(t) / u max ).

[0045] In the feeding state of the feeding hopper: the belt assembly 3 is fully attached to the feeding head body 1, the belt assembly fastens the connecting rod 27 to the shaft 39, the robotic arm docks with the connecting flange 7, and drives the feeding head to adjust its position so that the belt assembly 3 is parallel to the ground. At this time, the active roller 34 drives the driven roller 31 and the belt 33 to rotate through the built-in motor. The mash falls from the feeding head body 1 into the still pot along with the belt. At the same time, the dispersing electric roller 5 rotates synchronously through the built-in motor to disperse the mash in the feeding head body 1, so as to achieve uniform feeding.

[0046] Material grabbing state of the hopper: the belt assembly 3 is separated from the material head body 1, the belt assembly fastening rod 27 and shaft 39 are separated, the robotic arm docks with the connecting flange 7, and drives the material head to adjust its position so that the belt assembly 3 is perpendicular to the ground, the opening of the material head body 1 faces the material pile, and the robotic arm drives the material head to push towards the material pile, which can realize the loading.

[0047] The process of the hopper switching from the material grabbing state to the material spreading state is as follows: Cylinder 28 retracts, causing the belt assembly fastening link 27 to rotate around shaft 4 14. At this time, the belt assembly fastening link 27 is separated from shaft 6 39. Cylinder 1 21 retracts, causing link 1 24 and link 2 25 to rotate around shaft 2 12. Link 2 25 causes the belt assembly 3 to rotate around shaft 1 11. When the belt assembly 3 rotates to the correct position, the robotic arm docks with flange 7, causing the material head to adjust its position so that the belt assembly 3 is perpendicular to the ground, thus successfully switching to the material grabbing state.

[0048] The process of the hopper switching from the material grabbing state to the material spreading state is as follows: At this time, cylinder 1 21 extends, driving connecting rod 1 24 and connecting rod 2 25 to rotate around shaft 2 12. Connecting rod 2 25 drives belt assembly 3 to rotate around shaft 1 11. When belt assembly 3 is rotated to the position, cylinder 2 28 extends, driving belt assembly to engage connecting rod 27 to rotate around shaft 4 14. Belt assembly engages connecting rod 27 to engage shaft 6 39. The robotic arm docks with flange 7, driving the material head to adjust its position so that belt assembly 3 is parallel to the ground, thus successfully switching to the material spreading state.
