Description

Technical Field

[0001] This utility model relates to the field of facial mask processing technology, specifically a leak detection device for facial mask processing. Background Technology

[0002] Facial masks are a type of carrier for beauty and skincare products. Currently, facial masks made of powder, kaolin, non-woven fabric, silk, tencel, bio-cellulose, and non-woven fabric are widely used. After the facial mask is sealed in the can, problems such as incomplete sealing or poor sealing may occur due to factors such as improper installation of the mask sheet, dripping from the filling head, and temperature changes at the filling port during the production process. Therefore, it is necessary to test the sealing condition of the facial mask.

[0003] The prior art patent publication number CN214040513U discloses a mask sealing test device, which quickly tests the sealing performance by squeezing the mask with a spring and a rubber ring, uses a camera to facilitate observation of whether the mask is sealed, uses a tissue to facilitate observation of whether the liquid inside the mask is leaking out, uses a display screen to magnify the area, and allows staff to remove the mask with poor sealing to complete the test.

[0004] In the aforementioned patent, when the face mask packaging is squeezed and tested by spring and rubber ring, the face mask liquid inside the packaging may be squeezed out and adhere to the conveyor belt if the seal is not good, which will cause pollution to the conveyor belt and make it inconvenient to clean and maintain it. At the same time, it requires manual picking out of the leaked face mask, which increases the labor intensity and reduces the testing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a leak detection device for mask processing, in order to solve the problems mentioned in the background art, where mask liquid in the mask packaging may be squeezed out and adhere to the conveyor belt when the seal is not good, which will cause pollution to the conveyor belt, making it inconvenient to clean and maintain. At the same time, it requires manual picking out of the leaked mask, which increases the labor intensity and reduces the detection efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak detection device for facial mask processing, comprising a frame and a conveyor belt movably installed inside the frame. A support frame is fixedly installed on the top of the frame, and a detection component is movably installed inside the support frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a leak detection device for mask processing, including a frame 1 and a conveyor belt 2 movably installed inside the frame 1. A support frame 3 is fixedly installed on the top of the frame 1, and a detection component 4 is movably installed inside the support frame 3. A cleaning component 5 is fixedly installed at the rear bottom of the frame 1. The cleaning component 5 includes a water guide shroud 51 and a second vision camera 52. The water guide shroud 51 is fixedly installed at the rear bottom of the frame 1, and the second vision camera 52 is fixedly installed at the rear top of the frame 1. A diversion pipe 53 is fixedly installed inside the water guide shroud 51, and a rinsing head 54 is provided at the top of the diversion pipe 53. A pump 55 connected to the diversion pipe 53 is fixedly installed outside the water guide shroud 51, and a water receiving pipe 56 is fixedly connected to the bottom of the pump 55. A drain pipe 57 is fixedly connected to the bottom of the cover 51. A horizontal plate 58 is fixedly installed on the front side of the water guide cover 51. A telescopic electric cylinder 59 and a blower 511 are fixedly installed inside the horizontal plate 58. A wiping mechanism 510 is fixedly installed on the top of the telescopic electric cylinder 59. The visual camera 52 can capture the image of the conveyor belt 2. When the part of the conveyor belt 2 coated with mask liquid reaches the top of the water guide cover 51, the pump 55 delivers water to the diversion pipe 53 and sprays it onto the conveyor belt 2 from the rinsing head 54 to wash away the adhered mask liquid. The telescopic electric cylinder 59 drives the wiping mechanism 510 to rise and wipe the bottom of the conveyor belt 2 to remove water stains. With the fast blowing of the blower 511, the conveyor belt 2 can be dried quickly, making it easy to remove the residual mask liquid.

[0024] The wiping mechanism 510 includes a lifting plate 5101 fixedly installed on the top of the telescopic electric cylinder 59. The lifting plate 5101 has a slot 5102 with a side opening inside. A clip 5103 is movably engaged inside the slot 5102. A velvet pad 5104 is fixedly installed on the top of the clip 5103. The velvet pad 5104 is made of a soft and highly absorbent material, which can effectively absorb water stains on the conveyor belt 2. The clip 5103 can be pulled out of the slot 5102, so that the velvet pad 5104 can be easily and quickly replaced and cleaned, ensuring the durability of the wiping effect. Driven by the telescopic electric cylinder 59, the lifting plate 5101 can flexibly adjust the contact force and position between the velvet pad 5104 and the conveyor belt 2 to ensure uniform and thorough wiping.

[0025] The wiping mechanism 510 is located in front of the water guide cover 51, and the blower 511 is located in front of the wiping mechanism 510. The conveyor belt 2 is first rinsed and then the water stains are wiped off by the wiping mechanism 510. Then the blower 511 blows air to ensure the cleanliness of the surface of the conveyor belt 2. The blower 511 uses a high-efficiency motor that can generate a strong airflow to quickly remove the residual moisture on the conveyor belt 2.

[0026] The rinsing heads 54 are arranged horizontally at equal intervals, facing the conveyor belt 2, which can effectively cover the width of the conveyor belt 2. The horizontally equidistant arrangement of the rinsing heads 54 ensures the uniformity and consistency of rinsing, avoiding the problem of insufficient or excessive rinsing in some areas.

[0027] Please see Figure 4 and Figure 5 The detection component 4 includes a telescopic electric cylinder 41 fixedly installed at the top of the support frame 3, a pressure plate 42 fixedly installed at the bottom of the telescopic electric cylinder 41, a pusher electric cylinder 43 fixedly installed at the rear of the support frame 3, a pusher plate 44 fixedly installed inside the pusher electric cylinder 43, a vision camera 45 fixedly installed at the top of the support frame 3, and a control box 47 fixedly installed at the top of the support frame 3. The mask is conveyed by the conveyor belt 2 on the frame 1. The vision camera 45 evaluates the image. When the mask reaches the position of the pressure plate 42, the conveyor belt 2 stops, the pressure plate 42 descends to apply pressure. If the seal is poor, the mask liquid overflows. The vision camera 45 reconfirms the problem, the pressure plate 42 returns to its original position, and the pusher electric cylinder 43 pushes the pusher plate 44 to push and collect the problematic mask, thereby reducing manual labor intensity and improving detection efficiency.

[0028] A guide plate 46 corresponding to the push plate 44 is fixedly installed on the side of the frame 1. The design of the guide plate 46 and the push plate 44 allows the mask to slide outward and be collected when it reaches the guide plate 46.

[0029] Please see Figure 1 At the bottom of the frame 1, there is a waste liquid tank 6 located below the drain pipe 57. The waste liquid tank 6 is designed to collect the waste liquid generated during the mask testing process discharged from the drain pipe 57. The waste liquid tank 6 has sufficient capacity to ensure that it will not overflow frequently during continuous operation of the equipment, thereby reducing the frequency of monitoring by operators and the number of waste liquid treatments.

[0030] Working principle: The mask is conveyed by the conveyor belt 2 inside the frame 1. The image of the mask is captured and judged by the vision camera 45. When the mask reaches the pressure plate 42, the conveyor belt 2 stops and the pressure plate 42 is lowered by the control of the telescopic electric cylinder 41. The pressure plate 42 presses the mask packaging with a preset force. When there is a problem with the seal of the mask, some of the mask liquid inside will be squeezed out and stick to the conveyor belt 2. The image of the mask is captured by the vision camera 45 and judged. After the mask seal problem is determined, the telescopic electric cylinder 41 is reset and the pusher plate 44 is pushed forward by the pusher cylinder 43 to push the problematic mask to the guide plate 46 to slide down for collection. Masks without problems are conveyed to the rear by the conveyor belt 2 for collection.

[0031] The image on the conveyor belt 2 can be captured by the second vision camera 52. When the part of the conveyor belt 2 with the mask liquid is captured by the second vision camera 52, the intermittent movement of the conveyor belt 2 reaches the top of the water guide cover 51. The water is connected to the pipeline through the water inlet pipe 56 and the water quality diversion pipe 53 is pumped by the pump 55 to the rinsing head 54 to rinse the part of the conveyor belt 2 with the mask liquid. The wastewater flows down into the water guide cover 51 and is discharged into the waste liquid tank 6 through the drain pipe 57. The first telescopic electric cylinder 59 pushes the wiping mechanism 510 to move up and stick to the bottom of the conveyor belt 2. The water stains are wiped by the movement of the conveyor belt 2 and then reset. With the help of the blower 511, it is quickly dried by blowing air, which makes it easier to clean the adhered mask liquid. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
