Description

Technical Field

[0001] This utility model belongs to the field of disposable paper plate production technology, and in particular relates to a screening device for paper plate pulp with overflow warning. Background Technology

[0002] The disposable paper plate pulp screening equipment is a key device specifically designed for the disposable paper plate production process. Utilizing principles such as sieves, centrifugal force, or pressure difference, it performs high-precision screening of the pulp. This equipment can accurately separate fibers and impurities from the pulp, such as sand and metal fragments, ensuring that the pulp entering subsequent processes meets purity standards. By optimizing the screening process, it can improve the uniformity and quality of pulp fibers, providing high-quality raw materials for producing high-strength, smooth-surfaced disposable paper plates.

[0003] In the production process of paper trays, the pulp screening process is crucial. If the pulp juice accumulates in large quantities at the bottom outlet until it overflows, it will not only cause equipment failure and pollute the production environment, but also easily cause the pulp liquid to spill. Therefore, it is necessary to design a screening device for paper tray pulp with an overflow warning. The float level sensor monitors the pulp juice level in real time. Once the preset threshold is reached, the sensor mechanical temporary locking structure is triggered simultaneously to precisely and temporarily block the outlet. The two work together to achieve intelligent identification and active intervention of the overflow state, effectively preventing juice from spilling out. Utility Model Content

[0020] In the following description, embodiments of the present invention’s screening device for overflow warning of paper pulp for dinner plates will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a screening device for paper pulp with overflow warning according to an embodiment of the present invention. It includes a discharge port 2 connected to the right side of the screening device 1, a liquid outlet 3 connected to the central axis at the bottom of the screening device 1, a lower base plate 4 fixedly connected to the bottom of the support frame of the screening device 1, a storage tank 6 placed on the top of the lower base plate 4, a float level sensor 7 installed on the surface of the storage tank 6, a control box 8 inside the screening device 1, a side baffle 5 fixedly connected to the left side of the support frame of the screening device 1, the control box 8 installed on the right side of the side baffle 5, the float level sensor 7 electrically connected to the control box 8, a fixing block 10 on the top of the control box 8, an L-shaped plate 9 fixedly connected to the right side of the side baffle 5, the L-shaped plate 9 located on top of the control box 8, and the top of the L-shaped plate 9 fixedly connected to the fixing block 10. Connecting shells 11 are fixedly connected to the front and rear sides of the top of the fixing block 10, and the inner cavities of the two connecting shells 11 are rotatably connected by bearings. A belt 13 is connected between two pulleys 12 for transmission. A slider 15 is fixedly connected to the surface of the belt 13. A track 14 is fixedly connected to the top of the fixed block 10. The track 14 is fixedly connected to the slider 15. The track 14 guides the slider 15 when it slides, ensuring that the slider 15 does not deviate in direction and improving the stability of the slider 15. A pulp anti-blocking baffle 17 is provided at the bottom of the outlet 3. A motor 18 is installed on the left side of the front connecting shell 11. The control box 8 is electrically connected to the motor 18. The output shaft of the motor 18 is fixedly connected to the pulley 12. A connecting plate 16 is fixedly connected to the top of the slider 15. The connecting plate 16 is fixedly connected to the bottom of the pulp anti-blocking baffle 17. A rubber strip is installed on the rear side of the top of the pulp anti-blocking baffle 17. A sealing ring is installed at the connection between the storage tank 6 and the float level sensor 7.

[0022] Working Principle: When this utility model is in use, after the pulp screening device is running, the pulp is screened, and the solid components such as fibers are discharged from the discharge port 2, while the pulp juice flows into the storage tank 6 through the liquid outlet 3. Since there is an opening on the side wall of the storage tank 6 corresponding to the liquid level detection position, the float level sensor 7 is inserted into the storage tank 6 from the side. Sealing gaskets are used to ensure the sealing of the installation point to prevent liquid leakage from the storage tank 6. The float level sensor 7 installed on the storage tank 6 monitors the liquid level in the tank in real time. As the juice continues to flow in, the liquid level gradually rises. When the liquid level reaches the preset overflow threshold, the float level sensor 7 senses this change and transmits the signal to the control box 8. Upon receiving the signal, 8 sends a command to motor 18, which starts and drives pulley 12 to rotate. Pulley 12 drives slider 15 to slide on track 14 via belt 13. Slider 15 then drives connecting plate 16 to move. Connecting plate 16 pushes pulp anti-blocking baffle 17 to the bottom of outlet 3, temporarily blocking outlet 3 and preventing pulp juice from continuing to flow out. After the user cleans the juice in storage tank 6, the control box 8 can reverse the control of motor 18 to reset pulp anti-blocking baffle 17, and the device will return to normal operation. This achieves intelligent early warning and proactive intervention for pulp juice overflow, ensuring a clean production environment, reducing equipment failures, and improving the stability of the screening process.

[0023] In summary, this screening device for paper pulp with overflow warning works by triggering a float level sensor 7 to transmit a signal to the control box 8 when the liquid flowing from the outlet 3 reaches the full capacity of the storage tank 6. Then, through the coordinated operation of the control box 8, motor 18, and connecting plate 16, the connecting plate 16 drives the pulp anti-blocking baffle 17 to seal the bottom of the outlet 3. Finally, the liquid inside the storage tank 6 is poured to the designated position. This achieves the synergy of the two structures, enabling intelligent identification and proactive intervention, ensuring a clean production environment, reducing equipment malfunctions, and improving the stability of the screening process.
