Description

Technical Field

[0001] The utility model relates to the technical field of paint bucket production, in particular to a sealing test device for paint bucket production. Background Art

[0002] In the current packaging barrel sealing test device used in the production of waterproof coatings, the traditional testing method mainly adopts the air pressure test method. The barrel mouth on the barrel cover is manufactured in different sizes to meet different usage requirements. There will be manufacturing errors in the barrel body and the barrel cover during the production process. The sealing test usually only performs a packaging pressure test on the barrel body, and does not test whether the barrel body and the barrel cover can meet the packaging pressure conditions after being matched. This leads to unsatisfactory packaging effect after the packaging barrel is filled with coating because the barrel body and the barrel cover cannot reach the packaging pressure requirements, which ultimately affects the quality of the waterproof coating.

[0003] The patent with application number CN202121565223.4 discloses a sealing test device for packaging barrels for waterproof coating production. Its structure includes an air compressor, a mechanical rocker arm, an air pressure detection module, a packaging barrel, and a rack. The air compressor is placed on the left side of the rack, the mechanical rocker arm is installed above the rack platform, the air pressure detection module is installed on one side of the mechanical rocker arm, and the packaging barrel is placed on the platform of the rack. The air pressure detection module includes a detector, a pressure gauge, a sealing structure, and an inflation tube. The pressure gauge is fixed to the outer surface of the detector, the sealing structure is fixed to the lower end of the detector, and the inflation tube is installed at the left connection port of the detector. A movable push block that can flexibly adjust the sealing diameter is provided in the sealing structure, which can be suitable for barrels of different diameters, which is conducive to testing the overall sealing performance of the barrel body and barrel cover of the packaging barrel, and timely discovering packaging barrels that do not meet the packaging pressure, so as to avoid product quality problems of waterproof coatings due to unqualified packaging.

[0004] This structure achieves sealing of sealed buckets of different specifications by setting a sealing structure that adapts to the barrel mouth of the paint bucket. However, in actual use, the opening position and aperture of the barrel mouth may vary greatly, and debugging is more difficult during the adaptation process. It is difficult to adapt to paint buckets of more specifications. There are limitations that affect the test efficiency. In addition, the sealed bucket subjected to the force during the sealing and inflation process may shake, thereby affecting the test accuracy. Therefore, professionals in this field provide a sealing test device for paint bucket production to solve the above-mentioned problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In the utility model, a sealing test device for paint bucket production includes a mounting frame 1 and a conveyor belt 2 mounted thereon, an electric guide rail 3 is fixedly mounted on the inner wall of the mounting frame 1, a sealing push rod 4 is slidably mounted on the electric guide rail 3, a sealing cover 5 is fixedly mounted on the bottom of the sealing push rod 4, an air pressure sensor 6 is fixedly mounted on the inner wall of the sealing cover 5, a compressor 7 is fixedly mounted on the left side of the mounting frame 1, a hose 8 connected to the interior of the compressor 7 is installed, an air pipe 9 is fixedly connected to the top of the sealing cover 5, the bottom end of the air pipe 9 passes through and extends to the interior of the sealing cover 5, the end of the hose 8 away from the compressor 7 is connected to the top of the air pipe 9, a processor 10 is mounted on the mounting frame 1, the conveyor belt 2, the sealing push rod 4, the air pressure sensor 6 and the compressor 7 are all connected to the processor 10 signal, a limit component 11 is provided on the mounting frame 1, and the limit component 11 is connected to the processor 10 signal.

[0023] The limit assembly 11 includes two electric push rods 1101, which are respectively installed on the left and right sides of the mounting frame 1. The output ends of the electric push rods 1101 pass through and extend into the interior of the mounting frame 1. The output ends of the electric push rods 1101 are detachably connected to the limit plate 1102.

[0024] The limiting plate 1102 is in an arc-shaped state and is connected to the output end of the electric push rod 1101 through bolts.

[0025] The conveyor belt 2 is used to transport the paint bucket. Before conducting a sealing test on the paint bucket, the user needs to debug the equipment to adapt to the specifications of the paint bucket to be tested. The user controls the operation of the electric guide rail 3, and the electric guide rail 3 drives the sealing push rod 4 slidably mounted thereon to move horizontally, and the sealing cover 5 at the bottom moves accordingly, so that the sealing cover 5 is at the top of the opening of the paint bucket. Then, the limiting plate 1102 on the electric push rod 1101 needs to be disassembled and assembled to adapt to the specifications of the paint bucket. Then, the conveyor belt 2 transports the paint bucket to the inside of the mounting frame 1, so that the top opening of the paint bucket is at the bottom of the air pipe 9. After that, the conveyor belt 2 stops, and then the electric push rod 1101 drives the limiting plate 1102 to move to limit the paint bucket, and the sealing push rod 4 drives the sealing push rod 4 fixedly connected thereto The sealing cover 5 begins to move downward, and as the sealing push rod 4 continues to move downward, the bottom of the sealing cover 5 fits against the top of the paint bucket to achieve a seal. The air pipe 9 runs through the interior of the paint bucket. At this time, the air pressure sensor 6 monitors in real time and transmits the value to the processor 10. The compressor 7 starts to operate and sends gas into the interior of the paint bucket through the hose 8. The air pipe 9 does not fit against the inner wall of the paint bucket opening. The gas begins to diffuse into the paint bucket and the sealing cover 5, causing the value returned by the air pressure sensor 6 to steadily increase. The processor 10 can determine whether there is a sealing problem with the paint bucket by the returned value. If the air pressure value is lower than the set value and continues to not increase, there is a sealing problem. After the test is completed, the limit assembly 11 and the sealing cover 5 are reset, and the paint bucket can be continued to be transported for testing through the conveyor belt 2.

[0026] In the present utility model, a larger sealing cover 5 and a thinner air pipe 9 are provided to seal the openings of paint buckets of different specifications, and the electric guide rail 3 and the sealing push rod 4 are driven to adapt to the paint buckets of different specifications. The air pressure sensor 6 monitored by the compressor 7 can quickly determine whether there is a sealing problem in the paint bucket, so as to improve efficiency and practicality. At the same time, the limit component 11 can maintain the stability of the paint bucket during the test, so as to better complete the sealing of the opening and subsequent testing, thereby improving the test accuracy.

[0027] See also Figure 1 and 4 , wherein: a status indicator light 12 is fixedly installed on the top of the mounting frame 1, and the status indicator light 12 is connected to the processor 10 signal.

[0028] In the present invention, when it is determined that the paint bucket being tested has a sealing problem, the processor 10 will control the status indicator light 12 to flash. The status indicator light 12 can serve as a reminder to nearby users so that users can understand the status of the equipment in a timely manner.

[0029] See also Figure 2 , wherein: a limiting ring 13 is fixedly connected to the inner wall of the mounting frame 1 , and the hose 8 is located inside the limiting ring 13 .

[0030] In the present invention, the setting of the limit ring 13 can limit the hose 8, so that the hose 8 reduces its range of movement during the vertical movement of the sealing cover 5, avoiding long-term and large-scale movement of the hose 8 and shortening its service life.

[0031] See also Figure 2 and 3 , wherein: a sealing ring 14 is fixedly connected to the bottom of the sealing cover 5, and the sealing ring 14 is made of rubber material.

[0032] In the present invention, when the sealing cover 5 moves downward and contacts the paint bucket, the rubber sealing ring 14 will contact the top of the paint bucket, thereby further improving the sealing performance between the sealing cover 5 and the paint bucket and improving the accuracy of the test.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
