Description

Technical Field

[0001] The present invention relates to the technical field of facial mask processing, and in particular to a facial mask packaging sealing detection device and an application method. Background Art

[0002] Facial masks, a category of skincare products, serve as a carrier for beauty products. They are applied to the face to provide cosmetic benefits such as hydration, whitening, anti-aging, and oil balance. During the mask production process, they are typically sealed and packaged, and mask seal testing is a crucial step in ensuring mask quality and shelf life.

[0003] At present, the common mask seal detection methods in the existing technology are: 1. Directly observe the mask packaging bag manually to check whether the seal is flat and whether there are wrinkles, gaps or cracks. Although this method is simple and direct, it can only detect relatively obvious sealing problems. 2. The staff gently squeezes the mask bag with their hands to observe whether there is any gas leakage. If the mask bag quickly returns to its original shape after squeezing, it usually indicates a good seal; if it is found that the bag does not return to its original shape after being deflated, or bubbles emerge, there may be a loose seal. 3. Put the mask in water and observe whether there are bubbles. If the seal is not good, water will enter the packaging bag, and air will escape to form bubbles. The above detection method not only requires a lot of human resources, but also the detection process is relatively cumbersome, affecting the processing progress. For this reason, we propose a mask packaging seal detection device and application method to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a facial mask packaging sealing detection device and application method, which can weigh the packaged facial mask through a weighing sensor to detect whether its weight is qualified. The telescopic push plate rotates to push the weighed facial mask to the corresponding placement tray, and transports it through a conveyor belt. The pressure sensor applies pressure to the facial mask for sealing detection. During the detection process, the cross plate can stably support the bottom of the conveyor belt to avoid deformation of the conveyor belt due to pressure and affect the detection result, thereby ensuring the accuracy of the detection. It can automatically perform detection and can promptly feedback the detection results to the staff, without the need for staff to check by themselves, saving human resources and having high work efficiency.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1-6A facial mask packaging seal detection device includes a plurality of legs 1 and a conveyor belt 2 installed between the plurality of legs 1, a driving roller and a driven roller are rotatably installed between the plurality of legs 1, the driving roller is driven to rotate by a first driving motor, and the conveyor belt 2 is wound between the driving roller and the driven roller, so that the conveyor belt 2 can move to transport the packaged facial mask;

[0030] The upper end of the conveyor belt 2 is fixedly connected with a plurality of support rods 3 at equal intervals, and the upper ends of the plurality of support rods 3 are fixedly connected with a placing plate 4. The setting of the support rods 3 can reduce the contact area between the placing plate 4 and the conveyor belt 2, which is conducive to the movement of the conveyor belt 2. A loading assembly is provided on one side of the support leg 1, and the loading assembly rotates synchronously with the conveyor belt 2. The loading assembly includes a support plate 5 fixedly connected to the two support legs 1 on one side, the upper end of the support plate 5 is rotatably connected to the first rotating rod 6, and the upper end of the first rotating rod 6 is fixedly connected to the rotating disk 7. A plurality of placing cavities 8 are opened in an annular array on the rotating disk 7. The rotating disk 7 is placed at the discharge end of the facial mask packaging machine, and the packaged facial masks can be directly dropped into the placing cavity 8. The operation is simple. A plurality of placing cavities 8 are provided with weighing sensors 9. The weighing sensors 9 can weigh the packaged facial masks. If the weighed weight is within the standard range, the facial masks are qualified. If the weighed weight is not within the standard range, the facial masks may be empty or have other problems, and then timely feedback can be given to the staff for processing without the need for the staff to check by themselves.

[0031] The upper end of the support plate 5 is fixedly connected to the first vertical plate 10, and the second rotating rod 11 is rotatably connected to the first vertical plate 10. A transmission belt 12 is wound around the second rotating rod 11 and the rotating shaft of the driving roller. Under the connection action of the transmission belt 12, the second rotating rod 11 can rotate synchronously with the rotating shaft of the driving roller. The second rotating rod 11 is connected to the first rotating rod 6 through a bevel gear set 13. The bevel gear set 13 includes a first bevel gear sleeved on the side wall of the first rotating rod 6 and rotating coaxially with it, and the side wall of the second rotating rod 11 is sleeved with a second bevel gear rotating coaxially with it. The first bevel gear is meshed with the second bevel gear, so that under the connection action of the bevel gear set 13, the first rotating rod 6 can drive the rotating disk 7 to rotate synchronously with the driving roller, so that during the movement of the conveyor belt 2, the rotating disk 7 can rotate synchronously to transport the packaged facial mask;

[0032] The support leg 1 is provided with a pushing assembly for pushing the facial mask in the loading assembly to the corresponding placement tray 4. The pushing assembly includes a second vertical plate 14 fixedly connected to the top of one of the support legs 1, and the second vertical plate 14 is rotatably connected to a connecting rod 15. The connecting rod 15 is driven to rotate by a second driving motor 16 installed on the rear side wall of the second vertical plate 14. The end of the connecting rod 15 is fixedly connected to a telescopic pushing plate 17. The telescopic pushing plate 17 includes a shell fixedly connected to the end of the connecting rod 15, and a rod body extending to its outer side is slidably connected in the shell. A spring is connected between the rod body and the inner side wall of the shell. The spring is an elastic spring, which can push the rod body out of the shell in a natural state, and the end of the rod body is wrapped with a rubber layer. The setting of the spring can prevent the rod body from being pressed against the rotating disk 7 during the pushing process, making it difficult to rotate, and the setting of the rubber layer can prevent the rod body from squeezing the facial mask to cause damage, and can increase the friction between the facial mask and the facial mask, which is conducive to pushing the facial mask into the corresponding placement tray 4;

[0033] A U-shaped plate 18 is fixedly connected between the two legs 1 at the rear side, and a mounting plate 19 is fixedly connected to the front side wall of the U-shaped plate 18. A pressure sensor 25 for sealing detection of the film in the placement plate 4 and a cross plate 27 for supporting the conveyor belt 2 are connected to the mounting plate 19 through a driving assembly. The driving assembly includes a slide groove provided on the front side wall of the mounting plate 19, and a first connecting block 20 and a second connecting block 21 adapted thereto are vertically slidably connected in the slide groove. The inner bottom of the slide groove is rotatably connected to a double-headed screw 22 with threads passing through the first connecting block 20 and the second connecting block 21. The double-headed screw 22 is driven to rotate by a servo motor 23 installed at the upper end of the mounting plate 19. The servo motor 23 drives the double-headed screw 22 to rotate, and the first connecting block 20 and the second connecting block 21 can be moved closer to or away from each other under the action of the thread engagement. The front side wall of the first connecting block 20 is fixedly connected to the T-plate 24. The pressure sensor 25 is installed at the bottom of the T-plate 24. The pressure sensor 25 squeezes the packaged mask downward and feeds back the pressure value. When the reaction force provided by the mask is within the monitoring range of the pressure sensor 25, it indicates that the mask has no leakage and is well sealed. If the monitoring data exceeds the preset value, it indicates that the mask has leakage, which can be fed back through an electrical signal to remind the staff to deal with it in time. The operation is simple;

[0034] The front side wall of the second connecting block 21 is vertically slidably connected to a reinforcing plate 26, and the front side wall of the mounting plate 19 is fixedly connected to two blocks 28. The front side wall of the second connecting block 21 is provided with a guide slot, and a guide slider fixedly connected to the reinforcing plate 26 is slidably connected in the guide slot. A plurality of springs are connected between the guide slider and the inner bottom of the guide slot. The spring is an elastic spring, which can push the guide slider and the reinforcing plate 26 upward in the natural state. The cross plate 27 is fixedly connected to the upper end of the reinforcing plate 26, and the cross plate 27 and the block 28 are staggered front and back. When the reinforcing plate 26 abuts against the block 28, the cross plate 27 abuts against the bottom of the conveyor belt 2, which supports the conveyor belt 2. The pressure sensor 25 is in contact with the upper surface of the mask. When the double-headed screw 22 continues to rotate to make the pressure sensor 25 apply pressure to the mask for detection, under the limiting action of the block 28, the cross plate 27 continues to contact the bottom of the conveyor belt 2 to support it, so that the conveyor belt 2 remains horizontal and will not be deformed, and the cross plate 27 cannot continue to move upward. At this time, the reinforcing plate 26 slides in the guide groove through the guide slider, and the spring applies a reaction force to prevent the cross plate 27 from moving downward, so that the cross plate 27 can be stably in a horizontal state to support the bottom of the conveyor belt 2, thereby ensuring the accuracy of the detection and preventing the conveyor belt 2 from being deformed under pressure and affecting the accuracy of the detection results.

[0035] A material receiving box 29 is provided on the other side of the supporting leg 1 below the conveyor belt 2 . The facial masks after being tested can fall into the material receiving box 29 as the conveyor belt 2 moves and are collected in a centralized manner.

[0036] The present invention also discloses an application method of a facial mask packaging sealing detection device, comprising the following steps:

[0037] S1. Place the device at the discharge end of the facial mask packaging machine so that the packaged facial masks can fall into the placement cavity 8 on the rotating disk 7;

[0038] S2. Start the conveyor belt 2 to move. Under the connection of the transmission belt 12, the second rotating rod 11 rotates. Under the connection of the bevel gear set 13, the first rotating rod 6 rotates, so that the rotating disk 7 rotates synchronously with the conveyor belt 2.

[0039] S3, the weighing sensor 9 in the placement chamber 8 weighs the packaged facial mask and provides an electrical signal feedback of the weighed weight to determine whether the weight of the facial mask is within the standard range. When the placement tray 4 moves to the bottom of the placement chamber 8, the second drive motor 16 drives the telescopic pusher plate 17 to rotate through the connecting rod 15, pushing the weighed facial mask into the corresponding placement tray 4 and transporting it through the conveyor belt 2;

[0040] S4. When the placement tray 4 moves to the bottom of the pressure sensor 25, the conveyor belt 2 stops moving, and the servo motor 23 drives the double-headed screw 22 to rotate so that the first connecting block 20 and the second connecting block 21 are close to each other. The cross plate 27 is against the bottom of the conveyor belt 2 to support it. The pressure sensor 25 applies pressure to the facial mask in the placement tray 4 and feeds back the pressure value through an electrical signal. Whether the facial mask package is sealed is determined by whether the pressure value is within the standard range. After detection, the facial mask follows the movement of the conveyor belt 2 and falls into the receiving box 29 for centralized collection.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
