Description

Technical Field

[0001] This application relates to the technical field of food processing equipment, and in particular to a raw material pressure control device for a pasta processing equipment. Background Technology

[0002] In pasta processing, pressure control of the dough is a crucial factor affecting product quality. Currently, most pasta processing equipment uses pressure rollers with a fixed gap to press the dough. This method has significant drawbacks: when the physical properties of the dough, such as moisture and hardness, change, the pressure of the rollers cannot be automatically adjusted, easily resulting in dough that is too thick or too thin; if hard impurities are mixed into the dough, the fixed-gap rollers cannot avoid them in time, potentially causing equipment damage or dough tearing; traditional equipment often uses manual knobs to adjust the roller gap, resulting in low adjustment precision and no real-time pressure feedback, relying entirely on the operator's experience, making it difficult to guarantee the stability of product quality.

[0003] With the increasing scale and automation of the pasta processing industry, the requirements for the precision and automation of raw material pressure control are becoming increasingly stringent. Existing technologies, while some equipment attempts to adjust pressure using cylinders or hydraulic cylinders, lack effective pressure detection and feedback mechanisms, resulting in significant pressure fluctuations and failing to meet the demands of high-quality pasta production. Utility Model Content

[0016] In summary, this application includes the following beneficial technical effects:

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses a raw material pressure control device for a pasta processing equipment. (Refer to...) Figure 1-3 A raw material pressure control device for a pasta processing equipment includes a base 1, a pressure regulating mechanism, and a control system;

[0024] The base 1 is used to support and install the entire device;

[0025] A frame 2 is symmetrically fixedly connected to the upper surface of the base 1. A lower roller shaft 17 is rotatably installed at the bottom between the two frames 2. A fixed pressure roller 12 is fixedly fitted on the side wall of the lower roller shaft 17. A drive motor 11 is fixedly installed on one side of one of the frames 2. The output end of the drive motor 11 is fixedly connected to one end of the lower roller shaft 17 through a coupling (not shown in the figure).

[0026] Both frames 2 have through grooves 9 on their side walls. Slide seats 10 are slidably installed inside both grooves 9. An upper roller shaft 16 is rotatably installed between the two slide seats 10. A movable pressure roller 3 located directly above the fixed pressure roller 12 is fixedly mounted on the side wall of the upper roller shaft 16. Anti-slip patterns 18 are provided on the surfaces of both the fixed pressure roller 12 and the movable pressure roller 3.

[0027] The pressure regulating mechanism includes a servo cylinder 5 and two pressure sensors 19. A support plate 4 is fixedly connected to the top of the two frames 2. The servo cylinder 5 is fixedly installed in the middle of the upper surface of the support plate 4. A connecting plate 6 is fixedly connected to the output end of the servo cylinder 5. A fixed seat 15 is fixedly connected to the upper surface of the two slides 10. The two pressure sensors 19 are respectively installed inside the two fixed seats 15. A connecting rod 7 is symmetrically fixedly connected to the lower surface of the connecting plate 6. The bottom end of the connecting rod 7 moves through the top wall of the frame 2 and is fixedly connected to the upper surface of the fixed seat 15. A mounting groove is machined on the lower end face of the fixed seat 15. The pressure sensor 19 is fixedly installed in the mounting groove. The sensing surface of the pressure sensor 19 faces downward and contacts the top center position of the slide 10. A wiring hole 20 is opened on the side wall of the fixed seat 15 for connecting the pressure sensor 19 to the external circuit.

[0028] An alarm module 8 is fixedly installed on the side wall of one of the racks 2;

[0029] The control system is set on the base 1 and includes a PLC controller 14 and a touch screen 13. The PLC controller 14 is fixedly installed on the side wall of the base 1, and the touch screen 13 is set on the PLC controller 14. The PLC controller 14 is electrically connected to the pressure sensor 19, the servo cylinder 5, the drive motor 11, the touch screen 13 and the alarm module 8 respectively to realize intelligent control of the equipment.

[0030] The implementation principle of the blank pressure control device for a pasta processing equipment according to this application is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. In use, the pasta blank to be processed is placed between the fixed pressure roller 12 and the movable pressure roller 3. The drive motor 11 drives the lower roller shaft 17 and the fixed pressure roller 12 to rotate. The friction between the two pressure rollers drives the blank forward and completes the pressing. The operator inputs the target pressure value to the PLC controller 14 through the touch screen 13. The servo cylinder 5 starts and pushes the connecting plate 6 downward. The connecting rod 7 transmits the force to the slide block 10, causing the movable pressure roller 3 to move closer to the fixed pressure roller 12, applying pressure to the blank. The upper surfaces of the slide blocks 10 at both ends of the movable pressure roller 3 are in close contact with the sensing surfaces of the pressure sensors 19 inside the fixed base 15. When the blank is pressed, the reaction force received by the movable pressure roller 3 is transmitted to the pressure sensor 19 through the slide block 10. The pressure sensor 19 converts the pressure signal into an electrical signal and transmits it to the PLC controller 14 in real time. The PLC controller 14 compares the actual pressure value with the target pressure value. If the actual pressure is too low, it controls the servo cylinder 5 to increase the thrust, causing the movable pressure roller 3 to move downward to increase the pressure. If the actual pressure is too high, it controls the servo cylinder 5 to retract, causing the movable pressure roller 3 to move upward to decrease the pressure, forming a dynamic adjustment closed loop. When hard impurities are mixed into the billet, causing the pressure to rise sharply and exceed the set range, the PLC controller 14 immediately triggers the alarm module 8 to issue an audible and visual alarm, and simultaneously controls the servo cylinder 5 to quickly move the movable pressure roller 3 upward to prevent equipment damage or billet tearing. The cable of the pressure sensor 19 is connected to the control system through the wiring hole 20 on the side wall of the mounting base 15 to ensure stable signal transmission.

[0031] During this process, the blank pressure control device of the pasta processing equipment drives the movable pressure roller 3 to rise and fall through the servo electric cylinder 5, and the pressure sensor 19 detects the pressure value in real time. The control system realizes closed-loop adjustment to ensure the stability of the blank pressing pressure. At the same time, the overall structure is relatively simple and very convenient to use, which improves the practicality of the device.
