Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a linear filling machine for fermentation production. Background Technology

[0002] The primary purpose of using filling equipment in fermentation production is to meet the demands of efficient, precise, and industrialized production. Fermented products (such as alcoholic beverages, soy sauce, enzymes, and yogurt) typically contain active microorganisms or easily oxidized components. Manual filling can easily lead to contamination or quality fluctuations. Filling equipment, through automated control, ensures that high-precision flow meters or servo pump systems can accurately control the filling volume of each bottle during the filling process, guaranteeing product standardization. For fermentation liquids of different viscosities (such as high-viscosity enzymes or yogurt containing fruit pieces), the equipment can be adapted to piston, screw, and other filling methods to avoid sedimentation or stratification. Linear filling can also be linked with sterilization, capping, and other processes to form a continuous production line, significantly improving efficiency and reducing labor costs.

[0003] Existing fermentation linear filling machines suffer from misalignment between the bottle mouth and the filling head during the filling process. This is mainly due to the lack of a high-precision positioning and centering structure, which prevents the filling head from being perfectly perpendicular to the bottle mouth. This leads to liquid splashing, uneven filling volume, or bottle contamination, especially noticeable with high-viscosity fermentation liquids (such as enzymes and yogurt). This not only increases cleaning and maintenance costs but also poses a risk of oxidation or microbial contamination due to inadequate sealing. Furthermore, existing equipment mostly adopts a single-station filling mode, processing only one container at a time. After filling, mechanical reset or manual intervention is required, making continuous flow operation impossible. This results in low production efficiency, making it difficult to meet the production capacity demands of large-scale fermentation products. Frequent start-ups and shutdowns also exacerbate equipment wear and tear, further affecting the long-term stability and economic efficiency of operation. Utility Model Content

[0004] The purpose of this invention is to provide a linear filling machine for fermentation production, which solves the problem of misalignment between the bottle mouth and the filling head in the existing linear filling machine for fermentation during the filling process.

[0005] To achieve the above objectives, a linear filling machine for fermentation production is provided, comprising a conveyor frame. The machine is characterized in that a motor is fixedly connected to one outer end of the conveyor frame, a conveyor belt is installed inside the conveyor frame, and fixed seats are fixedly connected to the middle of both ends of the conveyor frame.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4This utility model discloses a linear filling machine for fermentation production, comprising a conveyor frame 1, a motor 2 fixedly connected to one end of the outer side of the conveyor frame 1, a conveyor belt 8 installed inside the conveyor frame 1, and the output shaft of the motor 2 directly connected to the transmission shaft of the conveyor belt 8 through a coupling to achieve the conveying effect of filling boxes 7. A fixed seat 4 is fixedly connected to the middle of both ends of the conveyor frame 1, and a bidirectional screw 17 is rotatably connected to the bottom of the fixed seat 4. Two threaded blocks 16 are threadedly connected to the bidirectional screw 17. A motor 5 is fixedly connected to one end of the bottom of the fixed seat 4, and the output end of the motor 5 is fixedly connected to the bidirectional screw 17. A sliding groove 18 is provided on the fixed seat 4, and a clamping plate 6 is fixedly connected to the upper end of the threaded block 16 through the sliding groove 18. By starting the motor 5, the bidirectional screw 17 is driven to rotate. Under the action of the threaded connection, the threaded block 16 can drive the clamping plate 6 to move inward, clamping both ends of the filling box 7 to achieve the effect of clamping both ends of the filling box 7.

[0027] A slide rod 19 is fixedly connected inside the slide chute 18, and a threaded block 16 is slidably connected to the slide rod 19. A vertical plate 3 is fixedly connected to the other end of the fixed seat 4. A cylinder 23 is fixedly connected to the outer end of the vertical plate 3. A baffle 24 is fixedly connected to the extended end of the cylinder 23. A filling box 7 is provided on the conveyor belt 8. By setting the slide rod 19 and the slide chute 18, the clamping plate 6 can be restricted to ensure the stability of the clamping plate 6 when clamping. At the same time, starting the cylinder 23 can drive the baffle 24 to extend and retract. The baffle 24 can block the filling box 7. A contact sensor is installed on the baffle 24. After contacting the filling box 7, it sends a signal to complete the clamping cycle. In order to prevent the filling box 7 from colliding when the baffle 24 blocks, the conveying speed of the conveyor belt 8 is slow, thus overcoming this problem.

[0028] A cylinder 25 is fixedly connected to the lower end of the conveyor frame 1 away from the motor 2. A connecting plate 26 is fixedly connected to the extended end of the cylinder 25. A cylinder 3 27 is fixedly connected to the upper end of the connecting plate 26. A baffle 28 is fixedly connected to the extended end of the cylinder 3 27. The cylinder 3 27 drives the baffle 28 to move inward, and the cylinder 25 drives the connecting plate 26 to push towards the filling box 7. Finally, the baffle 28 also contacts the filling box 7, achieving the effect of four-end centering and clamping. This ensures that the filling bottle mouth inside the filling box 7 can correspond to the filling head 22, improving the accuracy and efficiency of filling.

[0029] The outer ends of the conveyor frame 1 are provided with slide grooves 12, and the inner end of the connecting plate 26 is fixedly connected with a slider 15. The slider 15 is slidably connected inside the slide groove 12. By setting the slide groove 12 and the slider 15, the connecting plate 26 can be restricted to ensure the stability of the baffle 28 assembly when it moves.

[0030] Two sets of columns 10 are fixedly connected to the upper two ends of the conveyor frame 1. A top plate 14 is fixedly connected to the top of the columns 10. A hydraulic cylinder 13 is fixedly connected to the upper middle part of the top plate 14. A movable plate 11 is fixedly connected to the extended end of the hydraulic cylinder 13 through and downward. Activating the hydraulic rod 13 can drive the movable plate 11 and the filling components below to move downward, thereby adjusting the height of the filling head 22. The filling head 22 is equipped with a flow regulating valve, which can make corresponding adjustments according to the required filling speed and filling volume.

[0031] A liquid storage tank 9 is provided on one side of the conveyor frame 1. A filling tube 20 is installed through the upper end of the liquid storage tank 9. A filling pump 29 is installed in the middle of the filling tube 20. A filling cavity 21 is fixedly connected to the lower end of the movable plate 11. Several filling heads 22 are installed through the lower part of the filling cavity 21. The other end of the filling tube 20 is installed inside the filling cavity 21. When the filling pump 29 is started, the fermentation liquid in the liquid storage tank 9 enters the filling cavity 21 through the filling tube 20 and flows out downward through the filling heads 22, achieving a rapid filling effect. After filling is completed, the clamp 6 and the baffle are released, allowing the filling box 7 to continue to be conveyed out. The electronic components in this device are electrically connected based on the controller, and multi-stage collaborative control is achieved by relying on the programmable logic controller (PLC): First, the contact transmission... After the sensor detects that the filling box 7 touches the baffle 24, it inputs a level signal to the controller I / O module. The controller then triggers the inverter stop command of motor 2 through the logic program and simultaneously sends a pulse signal to motor 5 to start the preset clamping program. Motor 5 drives the bidirectional screw 17 to clamp the filling box 7 on both sides through closed-loop control. At the same time, the pressure sensor feeds back the clamping force data to the controller's PID adjustment module in real time to ensure that the container is not damaged. After the container is clamped in place, the photoelectric switch sends a confirmation signal back to the controller. The PLC then sends a pump start command to the filling pump 29 through Modbus communication to achieve the filling operation. Throughout the process, the controller ensures that the timing of the actions of each actuator is accurately matched through multi-threaded task scheduling. The HMI interface displays the running status synchronously and supports dynamic parameter adjustment.

[0032] Working Principle: During use, the operator places the bottle to be filled into the placement cavity inside the filling box 7. The placement cavity secures the bottle. Then, motor 2 is started, driving the conveyor belt 8 to rotate, thus transporting the filling box 7. At this time, cylinder 23 is activated, causing baffle 24 to move inward. When the filling box 7 moves to the position of baffle 24 and contacts it, the contact sensor at the inner end of baffle 24 sends a signal, and motor 5 is activated, driving the bidirectional screw 17 to rotate. Under the action of the threaded connection, the threaded block 16 drives the clamping plate 6 to move inward, thus moving the two sides of the filling box 7 inward. The end is clamped, and then cylinder 3 27 drives baffle 2 28 to move inward, and cylinder 2 25 drives connecting plate 26 to push towards filling box 7, so that baffle 2 28 also contacts filling box 7, achieving the effect of four-end centered positioning and clamping, ensuring that the filling bottle mouth inside filling box 7 can correspond to filling head 22. Finally, filling pump 29 is started, so that fermentation liquid in storage tank 9 enters filling chamber 21 through filling tube 20 and flows down through filling head 22, achieving the effect of rapid filling. After filling is completed, clamp 6 and baffle are released, so filling box 7 can continue to be conveyed out.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
