Technical Field
[0001] This utility model relates to the field of testing for biodegradable and environmentally friendly paper cups, specifically a testing device for biodegradable and environmentally friendly paper cups. Background Technology
[0002] Biodegradable and environmentally friendly paper cups are widely used in the catering and beverage industries due to their degradable and pollution-free characteristics. Their leak-proof performance is one of the important indicators for measuring product quality, which is directly related to the user experience and the market acceptance of environmentally friendly paper cups.
[0003] Currently, leak-proof testing of biodegradable and environmentally friendly paper cups mostly relies on manual operation. This involves workers manually injecting liquid into the paper cups and then observing whether any leakage occurs. This testing method is not only inefficient and difficult to meet the testing needs of large-scale production, but also prone to deviations in test results due to the difficulty in uniformly controlling factors such as the amount and speed of liquid injection and the stability of the paper cups. This affects the accuracy of judging the leak-proof performance of the paper cups. Furthermore, improper operation during manual testing may cause liquid spillage, polluting the testing environment and increasing the burden of subsequent cleanup work. Therefore, it is necessary to design a testing device for biodegradable and environmentally friendly paper cups to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a testing device for degrading environmentally friendly paper cups, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for degrading and environmentally friendly paper cups, including a base, a conveying device installed on the top of the base through a slot, a U-shaped plate fixedly installed on the top of the base, an electric telescopic rod fixedly installed on the top of the U-shaped plate through an opening, and a sealing plate fixedly installed at the bottom end of the electric telescopic rod.
[0006] A water tank is fixedly installed on the right side of the top of the U-shaped plate. A heating rod is fixedly installed at the bottom of the inner cavity of the water tank. A delivery pump is fixedly installed on the top of the water tank through an opening. The inlet end of the delivery pump is connected to a T-shaped pipe, and the outlet end of the delivery pump is connected to a delivery hose. The bottom end of the delivery hose passes through the U-shaped plate and the sealing plate in sequence and extends to the outside of the sealing plate.
[0007] Preferably, a sleeve is fixedly installed on the left side of the top of the sealing plate through an opening. A spring is welded to the top of the inner cavity of the sleeve, and a piston is welded to the bottom end of the spring. A red observation rod is fixedly installed on the left side of the piston. The left end of the red observation rod passes through the sleeve and extends to the outside of the sleeve. An movable opening for use with the red observation rod is provided on the left side of the sleeve.
[0008] Preferably, a first solenoid valve is provided on the surface of the T-tube, and a second solenoid valve is provided on the left side of the surface of the T-tube.
[0009] Preferably, the right side of the water tank is connected to a water inlet pipe.
[0010] Preferably, a third solenoid valve is provided on the surface of the water inlet pipe.
[0011] Preferably, a correction plate is fixedly installed on both sides of the inner wall of the U-shaped plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This testing equipment for biodegradable and environmentally friendly paper cups works by moving the paper cup under a sealing plate, then controlling the extension of an electric telescopic rod. After closing the second solenoid valve and opening the first solenoid valve, a delivery pump is started. The pump delivers hot water from the tank to the cup via a T-tube and a delivery hose. Then, the first solenoid valve is closed and the second solenoid valve is opened. The delivery pump then delivers hot gas from the tank to the cup. Once inside the cup, the gas pressure pushes the piston upwards. If there is a leak in the cup, the gas will escape through the leak. Operators can observe the rise and fall of the red observation rod to determine if there is a leak, thus improving testing efficiency and safety.
[0014] 2. This biodegradable and environmentally friendly paper cup testing equipment achieves automatic centering of the paper cup by placing the paper cup to be tested on top of the conveying device. After placement, the paper cup is conveyed forward by the conveying device. During the conveying process, the paper cup is pushed by contacting the calibration plate. Attached Figure Description

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.
[0021] Example 1
[0022] Please refer to Figure 1-4 As shown, this utility model provides a testing device for degradable and environmentally friendly paper cups, including a base 1, a conveying device 3 installed on the top of the base 1 through a slot, a U-shaped plate 2 fixedly installed on the top of the base 1, an electric telescopic rod 4 fixedly installed on the top of the U-shaped plate 2 through an opening, and a sealing plate 5 fixedly installed at the bottom end of the electric telescopic rod 4.
[0023] Specifically, a water tank 6 is fixedly installed on the right side of the top of the U-shaped plate 2. A heating rod 18 is fixedly installed at the bottom of the inner cavity of the water tank 6. A delivery pump 7 is fixedly installed on the top of the water tank 6 through an opening. The inlet end of the delivery pump 7 is connected to a T-shaped pipe 8, and the outlet end of the delivery pump 7 is connected to a delivery hose 9. The bottom end of the delivery hose 9 passes through the U-shaped plate 2 and the sealing plate 5 in sequence and extends to the outside of the sealing plate 5. A sleeve 12 is fixedly installed on the left side of the top of the sealing plate 5 through an opening. A spring 13 is welded to the top of the inner cavity of the sleeve 12. A piston 14 is welded to the bottom end of the spring 13. A red observation rod 15 is fixedly installed on the left side of the piston 14. The left end of the red observation rod 15 passes through the sleeve 12 and extends to the outside of the sleeve 12. A movable port 16 for cooperating with the red observation rod 15 is opened on the left side of the sleeve 12. A first solenoid valve 10 is provided on the surface of the T-shaped pipe 8, and a second solenoid valve 11 is provided on the left side of the surface of the T-shaped pipe 8. The right side of the water tank 6 is connected to... There is a water inlet pipe 17, and a third solenoid valve 20 is installed on the surface of the water inlet pipe 17. By setting a delivery pump 7, and controlling the extension of the electric telescopic rod 4 after the paper cup moves below the sealing plate 5, the extension of the electric telescopic rod 4 drives the sealing plate 5 to descend. After the sealing plate 5 descends, it can cover the top of the paper cup, thereby sealing the paper cup. Then, the second solenoid valve 11 is closed and the first solenoid valve 10 is opened, and the delivery pump 7 is started. The delivery pump 7 delivers hot water in the water tank 6 to the cup body through the delivery hose 9 via the T-shaped pipe 8. Then, the first solenoid valve 10 is closed and the second solenoid valve 11 is opened. At this time, the delivery pump 7 can deliver hot gas in the water tank 6 to the cup body. After the hot gas enters the cup body, the gas pressure can push the piston 14 upward. If there is a leak in the cup body, the gas will be discharged through the leak. At this time, the staff can judge whether there is a leak in the cup body by observing whether the red observation rod 15 rises or falls, which improves the efficiency and safety of detection.
[0024] Among them, a correction plate 19 is fixedly installed on both sides of the inner wall of the U-shaped plate 2. By setting the correction plate 19 and placing the paper cup to be tested on the top of the conveying device 3, the paper cup can be conveyed forward by the conveying device 3 after placement. During the conveying process, the paper cup can be pushed by contacting the correction plate 19, thereby achieving the effect of automatically centering the paper cup.
[0025] Working Principle: This utility model is a testing device for biodegradable and environmentally friendly paper cups. The paper cup to be tested is placed on top of the conveying device 3. After placement, the paper cup is conveyed forward by the conveying device 3. During conveying, the paper cup is pushed by contacting the calibration plate 19, thereby achieving automatic centering of the paper cup. After the paper cup moves below the sealing plate 5, the electric telescopic rod 4 extends, causing the sealing plate 5 to descend. After the sealing plate 5 descends, it covers the top of the paper cup, thus sealing the paper cup. Then, the second solenoid valve 11 is closed and the second solenoid valve 11 is opened. After the first solenoid valve 10 is activated, the delivery pump 7 is started. The delivery pump 7 can deliver hot water from the water tank 6 to the cup body through the delivery hose 9 via the T-tube 8. Then, the first solenoid valve 10 is closed and the second solenoid valve 11 is opened. At this time, the delivery pump 7 can deliver hot gas from the water tank 6 to the cup body. After the hot gas enters the cup body, the gas pressure can push the piston 14 upward. If there is a leak in the cup body, the gas will be discharged through the leak. At this time, the staff can judge whether there is a leak in the cup body by observing whether the red observation rod 15 rises or falls, which improves the efficiency and safety of the detection.
