Description

Technical Field

[0001] The utility model relates to the technical field of packaging detection, in particular to a device for detecting the sealing performance of tea packaging. Background Technique

[0002] After the tea is fried, in order to facilitate storage and transportation, it is generally sealed and packaged by a machine. Moreover, the tea contains various ingredients beneficial to the human body, such as catechins, caffeine, etc. However, these ingredients are prone to deliquescence in a high-humidity environment, resulting in phenomena such as tea mildew and loss of aroma. Therefore, through the sealing performance detection, the integrity of the tea packaging can be ensured, preventing the intrusion of external moisture and oxygen, thereby protecting the quality of the tea.

[0003] Chinese patent document CN220912575U discloses a device for detecting the sealing performance of the sealing of a health tea packaging bag. It is connected by a second side plate and a connecting plate. A fixed frame is provided on the top surface of the second side plate, and a top plate is provided on the top surface of the fixed frame. In this application, the downward movement of the placement plate can drive the packaged tea on the placement plate to move downward into the water tank until it is completely immersed in the water. By observing whether there are bubbles in the clear water in the water tank, it can be judged whether the packaged tea is sealed. Moreover, the automation degree of this device is relatively high, reducing the labor intensity of workers and improving work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 shown, a tea packaging airtightness detection device includes a support frame 1. A guiding and detecting component 2 is fixedly installed at the right rear part of the rear side of the support frame 1. A water draining component 3 is fixedly installed in the middle of the guiding and detecting component 2. A pressing and feeding component 4 is fixedly installed at the right front part of the front side of the support frame 1.

[0027] Through the guiding and detecting component 2, the tea packaging can be brought into the water. The tea packaging is clamped between the support filter plate 27 and the extrusion plate 45 due to the movement of the support filter plate 27 and the extrusion plate 45, which is convenient for the detection and discharging of the packaging. Through the water draining component 3, after the packaging leaves the water surface and when the extrusion plate 45 is above the support filter plate 27, the cam 32 rotates and intermittently presses the roller 33, so that the sliding plate 25 is stressed and vibrates through two spring guide shafts 34, thereby accelerating the water draining effect of the packaging and preventing the tea packaging from carrying a large amount of water and affecting the operation of the electric conveyor belt 49. Through the pressing and feeding component 4, the tea packaging with a lighter mass can be immersed in the water so that it can be completely wrapped by the water, increasing the accuracy of the detection structure. During subsequent discharging, the moving frame 41 can drive the pushing plate 46 to push the packaging onto the electric conveyor belt 49 due to the drive of the electric push rod 48, without manual contact, and has strong practicability.

[0028] As Figure 3 and Figure 4 shown, the guiding and detecting component 2 includes a fixing frame 21. The bottom of the front side of the fixing frame 21 is fixedly installed with the right rear part of the rear side of the support frame 1. The middle of the upper end of the fixing frame 21 is fixedly installed with a cylinder 22. The output end of the cylinder 22 penetrates through the top of the fixing frame 21 and is fixedly installed with a moving plate 23. The left and right sides of the moving plate 23 are slidably connected with the left and right parts of the inner wall of the fixing frame 21.

[0029] The output end of the cylinder 22 can drive the moving plate 23 to move up and down.

[0030] As Figure 4 shown, an installation groove 24 is opened on the front side of the moving plate 23. A sliding plate 25 is slidably connected to the inner wall of the installation groove 24. Both the left and right parts of the front side of the sliding plate 25 are fixedly installed with connecting frames 26. One end of the two connecting frames 26 far from the sliding plate 25 is fixedly installed with a support filter plate 27.

[0031] Through the up and down movement of the moving plate 23, the two connecting frames 26 can drive the support filter plate 27 to move up and down. When the tea packaging is placed on the support filter plate 27, the support filter plate 27 can drive it to enter or leave the water surface. Among them, there is a certain distance between the four sides of the support filter plate 27 and the four surfaces of the inner wall of the water tank 28.

[0032] As Figure 2 and Figure 3As shown, a water tank 28 with an open top is fixedly installed on the right side of the inner wall of the support frame 1. Observation windows are provided on all four sides of the water tank 28. A drain pipe 29 is fixedly installed at the lower end of the water tank 28, and a cover 210 is threadedly connected to the bottom of the inner wall of the drain pipe 29.

[0033] When the water in the water tank 28 needs to be replaced, the cover 210 can be rotated and screwed out. The observation windows on the sides of the water tank 28 facilitate the staff to observe whether the packages are bubbling in the water.

[0034] As Figure 5 shown, the water draining assembly 3 includes a motor 31. The front side of the motor 31 is fixedly installed with the left part of the rear side of the moving plate 23. The output end of the motor 31 penetrates through the front part of the inner wall of the installation slot 24 and is fixedly sleeved with a cam 32. A roller 33 is rotatably connected to the left side of the sliding plate 25, and the outer surface of the cam 32 abuts against the outer surface of the roller 33.

[0035] The output end of the motor 31 can drive the cam 32 to rotate. When the cam 32 rotates, it can intermittently contact the roller 33, so that the sliding plate 25 slides in the installation slot 24.

[0036] As Figure 5 shown, spring guide shafts 34 are fixedly installed on both the upper and lower parts of the right side of the sliding plate 25, and the right ends of the two spring guide shafts 34 are fixedly connected to the right part of the inner wall of the installation slot 24.

[0037] When the sliding plate 25 is stressed, it squeezes the two spring guide shafts 34. When the sliding plate 25 is not stressed, the elastic restoring force of the two spring guide shafts 34 can drive the sliding plate 25 to reset, thereby realizing the vibration of the sliding plate 25 and the support filter plate 27, so that the tea packages on the support filter plate 27 can be quickly dewatered.

[0038] As Figure 6 shown, the pressing and feeding assembly 4 includes a moving frame 41. The bottom of the rear side of the moving frame 41 is slidably connected to the front side of the support frame 1. A regulating screw 42 penetrating through the top of the moving frame 41 is threadedly connected to the middle of the upper end of the moving frame 41. The lower end of the regulating screw 42 is rotatably connected to a driving plate 43. The left and right sides of the driving plate 43 are slidably connected to the left and right parts of the inner wall of the moving frame 41. Support brackets 44 are fixedly installed on both the left and right parts of the rear side of the driving plate 43. An extrusion plate 45 is fixedly installed at one end of the two support brackets 44 away from the driving plate 43. A number of through holes are provided at the upper end of the extrusion plate 45. The extrusion plate 45 is located above the support filter plate 27.

[0039] By rotating the regulating screw 42, the driving plate 43 can move up and down on the left and right parts of the inner wall of the moving frame 41. The driving plate 43 drives the support brackets 44 and the extrusion plate 45 to move downward, and the push plate 46 is inserted into the limiting groove 47 accordingly, so that the packages with lighter weight can be immersed in the water and clamped between the extrusion plate 45 and the support filter plate 27. The number of through holes can reduce the resistance of water to the extrusion plate 45.

[0040] As Figure 2 and Figure 6 shown, a push plate 46 is fixedly installed on the right side of the extrusion plate 45. A limit groove 47 matching the bottom of the push plate 46 is opened in the upper right part of the support filter plate 27. An electric push rod 48 is fixedly installed on the left part of the front side of the support frame 1. The output end of the electric push rod 48 is fixedly connected to the bottom left side of the moving frame 41. An electric conveyor belt 49 is fixedly installed on the left part of the inner wall of the support frame 1.

[0041] The output end of the electric push rod 48 can pull or push the moving frame 41 to move. When the moving frame 41 moves, the extrusion plate 45 is located above the support filter plate 27. The push plate 46 moves along with the moving frame and pushes the package onto the electric conveyor belt 49, facilitating the discharging of materials.

[0042] The working principle of the present utility model: Before detection, the extrusion plate 45 is located on the top of the support filter plate 27. The tea package is placed on the support filter plate 27. The air cylinder 22 is started, and its output end can drive the moving plate 23 to move downward. The support filter plate 27 drives the package into the water. The adjusting screw 42 is rotated, and the driving plate 43 can move up and down in the left and right parts of the inner wall of the moving frame 41. The driving plate 43 drives the bracket 44 and the extrusion plate 45 to move downward. The push plate 46 is inserted into the limit groove 47 accordingly. The packages with lighter weight are immersed in the water and clamped between the extrusion plate 45 and the support filter plate 27. The staff observes through the observation window whether the packages bubble in the water.

[0043] If the package is qualified, the adjusting screw 42 is rotated to reset the extrusion plate 45. The support filter plate 27 drives the package away from the water surface through the drive of the air cylinder 22. Subsequently, the motor 31 is started, and its output end can drive the cam 32 to rotate. When the cam 32 rotates, it can intermittently contact the roller 33, so that the sliding plate 25 slides in the installation groove 24. When the sliding plate 25 is stressed, it presses two spring guide shafts 34. When the sliding plate 25 is not stressed, the elastic restoring force of the two spring guide shafts 34 can drive the sliding plate 25 to reset, thereby realizing the vibration of the sliding plate 25 and the support filter plate 27, and enabling the tea packages on the support filter plate 27 to be quickly dewatered.

[0044] After the water draining is completed, the output end of the electric push rod 48 can drive the moving frame 41 to move. The push plate 46 moves accordingly and pushes the package onto the electric conveyor belt 49. The electric conveyor belt 49 conveys the package out.
