Description

Technical Field

[0002] With the improvement of health awareness and the change of consumption concepts in modern society, consumers pay more and more attention to oral care, which has led to the rapid development of the toothpaste market. The types of toothpaste are becoming more diversified, and consumers' functional requirements for toothpaste are becoming more and more abundant. The production process of toothpaste includes steps such as metering, gel making, paste kneading, grinding, vacuum degassing, and aging. Among them, the vacuum degassing step can discharge the bubbles in the toothpaste paste to improve the quality of the toothpaste paste.

[0003] During the degassing process of toothpaste, a large number of bubbles will be generated, and the bubble level will also rise rapidly. The existing vacuum degassing equipment has a low degree of automation. During the degassing process, the bubbles generated by the paste in the vacuum tank are easy to contact the cover or overflow when the liquid level rises rapidly. Manual monitoring through the observation window is required, which is inefficient. Some equipment may be equipped with a liquid level detection probe, and the bubble level must rise to the probe before it can be detected and a signal can be sent. Not only is the accuracy not precise enough, but it is also inconvenient to clean, reducing the practicality of the equipment. Utility Model Content

[0022] Specifically, the inner cavity of the tank body 100 is a accommodating cavity for the paste, and the top is covered with a sealing cover 110 that seals the tank body 100. The four sides of the sealing cover 110 are detachably locked and connected to the tank body 100. A transparent visual mirror is fixed to the middle of the sealing cover 110 through a threaded connection to form an observation window 120. The inner cavity of the tank body 100 can be observed through the observation window 120. The infrared sensor 200 is fixed to the sealing cover 110 and is located on the upper side of the observation window 120. The infrared rays output by the output end of the infrared sensor 200 are transmitted through the observation window 120. 120 penetrates into the tank body 100 to monitor the high level of the bubble liquid; the side wall of the tank body 100 is provided with a vacuum connection port 130, which is connected to the vacuum pump 400 through a pipeline, and the pressure sensor 300 installed on the sealing cover 110 can detect the pressure value in the tank body 100 in real time; and the exhaust valve 140 is used to discharge the gas inside the tank body 100; the infrared sensor 200 and the vacuum pump 400 are electrically connected to the PLC controller 500, and the degassing process can be controlled by a program, and the degree of automation is high. High; in this embodiment, after the toothpaste is placed in the tank body 100, the degassing process is started. Under the control of the PLC controller 500, the vacuum pump 400 starts to run, and the paste starts to degas and a large number of bubbles are generated, and the liquid level rises rapidly. Under the monitoring of the infrared sensor 200, when the liquid level reaches a certain height, the PLC controller 500 controls the vacuum pump 400 to stop pumping, and connects the tank body 100 to the atmospheric pressure through the exhaust valve 140. When the liquid level of the bubbles drops to a certain height, the vacuum pump 400 restarts, and the above steps are repeated until the bubble level of the toothpaste paste remains stable during the air extraction. The infrared sensor 200 detects that the bubble level remains stable for a certain period of time, that is, the PLC controller 500 and the infrared sensor 200 detect and judge that the liquid level of the paste and the rising distance of the bubbles during degassing are basically stable, and the degassing step can be ended, the vacuum pump 400 stops running and the exhaust valve 140 is opened; the degassing process of the toothpaste paste is automated, and the degassing progress is accurate, no manual monitoring is required, and the processing efficiency is high.

The exhaust valve 140 provided on the tank body 100 is used to open the exhaust valve 140 after vacuum is drawn during the degassing process, so that the inner cavity of the tank body 100 is connected to the atmospheric pressure. In order to ensure normal exhaust, two exhaust valves 140 are provided, one of which can be used as a spare exhaust valve 140 when in use. When one of the exhaust valves 140 is blocked, the other exhaust valve can continue to work, thereby improving the safety performance of the equipment; in addition, the second exhaust valve 142 is located at the lower side of the first exhaust valve 141, and the vacuum connecting port 130 and the first exhaust valve 141 are located at the same horizontal position; the second exhaust valve 142 is located in the middle of the tank body 100, and the first exhaust valve 141 and the vacuum connecting port 130 located on the upper side are closer to the top of the tank body 100. When the paste rises, it is not easy to be blocked by bubbles, thereby ensuring smooth passage.

[0024] Furthermore, the sealing cover 110 extends with a fixed tube 111 connected to the inner cavity of the tank body 100, and the pressure sensor 300 is a vacuum pressure gauge, which is sealed and fixed to the fixed tube 111.

The mesh frame 180 is fixed in the inner cavity of the tank body 100. When the toothpaste paste is degassed, it is usually placed in a bag. When the paste is taken out, it is not easy to adhere to the inner cavity of the tank body 100. The setting of the mesh frame 180 facilitates the fixing and disassembly of the bag body and can support the bag body.

[0028] Furthermore, a connection seat 190 is provided at the top of the tank body 100, and a connection member 191 is pivotally connected to the connection seat 190, and the other end of the connection member 191 is fixed to the sealing cover 110.
