Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection, in particular to a glue liquid level detection component. Background Art

[0002] In the process of adhesive production, packaging and use, accurate measurement of the liquid level in the glue container is crucial to ensure product quality and production efficiency.

[0003] At present, the glue level measurement methods available on the market mainly include float type, capacitance type, ultrasonic type, etc.

[0004] Among them, the float type liquid level gauge measures based on the principle that the float moves with the change of liquid level. However, since the float of specific size needs to be customized for hoses of different diameters, this method is complicated to operate and has high cost in practical application. In addition, the size and shape of the float directly affect the accuracy of the measurement results, and any slight deviation may lead to large measurement errors.

[0005] Capacitive level gauges reflect changes in liquid level by detecting changes in capacitance. Currently, capacitive level gauges are set on one side of the hose. The principle is that the difference in dielectric constant between liquid and air causes changes in capacitance. However, when the viscosity of the glue is high, the glue will still "hang on the wall" on the tube wall after the glue level drops. When the glue remains near the capacitive level gauge, the capacitive level gauge will still sense that there is glue on the inner wall of the hose, resulting in a misjudgment.

[0006] Ultrasonic level meters overcome the limitations of the above methods to a certain extent due to their non-contact measurement method, and can flexibly adapt to hoses of different diameters. However, the measurement accuracy and stability of ultrasonic level meters are easily affected by environmental factors, such as temperature, humidity, dust in the air, and the characteristics of the sound wave reflection surface, etc. These factors may cause fluctuations in the measurement data, thereby affecting the reliability and repeatability of the measurement.

[0032] Example 1

[0033] Combination Figures 1 to 3 As shown, the glue level detection component of the utility model is schematically shown, including a bearing component 10, an electric field sensing component 20 and an interactive component 30. The bearing component 10 is made of a flexible material, specifically polyvinyl chloride.

[0034] like Figure 1 The bearing component 10 is in the shape of a circular ring, and the electric field sensing component 20 is provided on its inner wall, so that the electric field sensing component 20 is in the shape of a closed ring. The bearing component 10 can be sleeved on the outer wall of the hose, so that the electric field sensing component 20 fits the outer wall of the hose. When the level of the glue in the hose is higher than the annular electric field sensing component 20, the electric field value sensed by the electric field sensing component 20 is higher. When the level in the hose is lower than the annular electric field sensing component 20, even if there is glue residue in the hose, the electric field value sensed by the electric field sensing component 20 is lower. In this way, the level of the glue in the hose can be accurately detected.

[0035] The interactive component 30 is arranged on the bearing component 10, and the interactive component 30 is electrically connected to the electric field sensing component 20. The interactive component 30 is used to receive the sensing value output by the electric field sensing component 20 and send out an acoustic signal and / or an optical signal. When the liquid level of the glue in the hose is higher than the annular electric field sensing component 20, the electric field value sensed by the electric field sensing component 20 is higher, and the interactive component 30 can display a first optical signal. The production staff can see that the current hose liquid level is higher by observing the first optical signal; when the liquid level in the hose is lower than the annular electric field sensing component 20, the electric field value sensed by the electric field sensing component 20 is lower, and the interactive component 30 can display a second optical signal. The production staff can see that the current hose liquid level is lower by observing the first optical signal, and can prepare to replace the hose with more glue or add glue into the hose.

[0036] Of course, an electric field sensing processing chip can also be adaptively arranged on the carrier component 10, the electric field sensing component 20 is electrically connected to the electric field sensing processing chip, and the electric field sensing processing chip is electrically connected to the interactive component 30 (that is, the electric field sensing component 20 is electrically connected to the interactive component 30 through the electric field sensing processing chip), and the electric field sensing processing chip is used to process the electric field value generated by the electric field sensing component 20, and then output a display signal or an audio signal to the interactive component 30. Among them, the electric field sensing component 20 includes a plurality of mutually parallel sensing cables, the cross-sectional area of ​​the sensing cables is preferably 0.5 mm², and the ends of the sensing cables are connected to the electric field sensing processing chip.

[0037] Specifically, Figure 2 The bearing component 10 has a head end 11 and a tail end 12. The head end 11 of the bearing component 10 is provided with a connecting mechanism 40. The tail end 12 of the bearing component 10 is detachably connected to the connecting mechanism 40 so that the bearing component 10 is annular. The connecting mechanism 40 can also adjust the diameter of the annular shape of the bearing component 10. Figure 2 and Figure 3 The connection mechanism 40 includes a connection ring 45, a first connection plate 41, a second connection plate 42 and an adjustment member 43, and the tail end 12 of the bearing member 10 is inserted through the connection ring 45. The first connection plate 41 is located on the inner side wall of the bearing member 10, and the second connection plate 42 is located on the outer side wall of the bearing member 10. The first connection plate 41 and the second connection plate 42 are arranged opposite to each other and a distance is provided between them. The two ends of the adjustment assembly are respectively connected to the first connection plate 41 and the second connection plate 42. The adjustment assembly is used to adjust the distance between the first connection plate 41 and the second connection plate 42. When the distance between the first connection plate 41 and the second connection plate 42 is reduced, the first connection plate 41 and the second connection plate 42 clamp the head end 11 and the tail end 12 of the bearing member 10, and when the distance between the first connection plate 41 and the second connection plate 42 is increased, the first connection plate 41 and the second connection plate 42 release the head end 11 and the tail end 12 of the bearing member 10, and at this time, the annular diameter of the bearing member 10 is allowed to be adjusted. The adjusting assembly includes an adjusting screw and a first connecting hole opened in the first connecting plate 41 and a second connecting hole opened in the second connecting plate 42, wherein the second connecting hole has an internal thread, and the adjusting screw passes through the first connecting hole and the second connecting hole in sequence. The distance between the first connecting plate 41 and the second connecting plate 42 can be adjusted by rotating the adjusting screw.

[0038] In order to prevent the connecting component from sliding abnormally relative to the supporting component 10, the first connecting plate 41 is provided with an anti-slip silicone 44 on one side of the inner wall of the supporting component 10, and / or the second connecting plate 42 is provided with an anti-slip silicone 44 on one side of the outer wall of the supporting component 10. The anti-slip silicone 44 can increase the friction between the first connecting plate 41 (or the second connecting plate 42) and the supporting component 10.

[0039] Example 2

[0040] The difference between this embodiment and embodiment 1 is that Figure 4 As shown, the glue level detection assembly also includes a tube body 50 for containing glue, a bearing component 10 is arranged around the tube body 50, and the electric field sensing component 20 is attached to the outer wall surface of the tube body 50. A sealing piston 51 is arranged in the tube body 50, and the sealing piston 51 is slidably connected to the inner wall surface of the tube body 50. When the glue liquid level in the rubber tube is higher than the annular electric field sensing component 20, the electric field value sensed by the electric field sensing component 20 is higher. When the liquid level in the rubber tube is lower than the annular electric field sensing component 20, even if there is glue liquid remaining in the rubber tube, the electric field value sensed by the electric field sensing component 20 is lower. In this way, the glue liquid level in the rubber tube is accurately detected. After the tube body 50 is filled with glue liquid, the sealing piston 51 in the tube body 50 contacts the glue liquid. As the glue liquid level drops, the sealing piston 51 will slide relative to the inner wall surface of the tube body 50 and follow the glue liquid level to drop.

[0041] Even if the viscosity of the glue is too high and causes the sealing piston 51 to stop sliding, when the glue level drops below the annular electric field sensing component 20, the electric field value sensed by the electric field sensing component 20 is low, it can be judged that the glue level has dropped below the preset critical value. At this time, the interactive component 30 prompts the production personnel to replace the hose or add glue to the hose in time.

[0042] Example 3

[0043] The difference between this embodiment and embodiment 1 is that, in order to monitor the glue level of the remote hose, the glue level detection assembly further includes a communication component provided on the bearing component 10, the communication component is electrically connected to the electric field sensing component 20, and the communication component can be wirelessly connected to the remote monitoring device to send the electric field value processed by the electric field sensing processing chip to the remote monitoring device. The communication component can be a 4G, 5G wireless communication chip, a WiFi wireless communication chip, a Bluetooth wireless communication chip, or a combination of all of the above wireless communication chips.

[0044] To sum up, the electric field sensing component 20 on the inner wall of the bearing component 10 is in the shape of a closed ring. When the bearing component 10 is sleeved on the hose, whether the glue in the hose is located on the inner side of the electric field sensing component 20 will affect the electric field value sensed by the electric field sensing component 20. Even if the glue in the hose remains on the tube wall, the annular electric field sensing component 20 can still sense the changing electric field value, and the electric field value is output to the interactive component 30, which generates an acoustic signal and / or an optical signal to prompt production personnel to pay attention to the glue level in the hose.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
