[0002] Tinplate cans, commonly known as iron cans and iron boxes, are cans made of tinplate, which is tin plated on the surface of iron to play a protective role. Generally speaking, for the sake of beautiful packaging, printing is adopted, commonly known as printed iron cans. Usually, they are classified into mooncake cans, DVD iron cans, chocolate cans, iron tea cans, coffee cans, biscuit cans, health product cans, beauty cans, handle cans, savings cans, sealed cans, milk powder cans, wine cans, Christmas cans, gift cans, candle cans, metal barrels, badges, coasters, tinplate toys, music boxes, cigarette boxes, stationery boxes, CD boxes, cigarette cases, various special-shaped can molds, etc. Classified by shape, they are divided into round cans, rectangular cans, square cans, oval cans, heart-shaped cans and special-shaped cans (car-shaped / cartoon animal-shaped), etc. Tinplate cans are stronger and have better rigidity than other packaging containers, such as plastic, glass, paper containers, etc., and are not easy to break. They can be used not only for small-scale sales packaging, but also as the main containers for large-scale transportation packaging. Tinplate cans have excellent barrier properties, gas barrier properties, moisture resistance, light shielding properties, and fragrance preservation properties. In addition, the sealing is reliable, which can reliably protect the products.

[0003] When an existing device for detecting the high-pressure resistance performance of round tinplate cans is in use, it can only detect the external compressive resistance of tinplate cans, cannot perform high-pressure detection on the inside of tinplate cans, and cannot seal the tinplate cans in an open state conveniently. The installation and detection are rather cumbersome, and the tinplate cans cannot be fixed inside the detection device conveniently. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a device for detecting the high-pressure resistance performance of tinplate cans, which solves the problems that when an existing device for detecting the high-pressure resistance performance of round tinplate cans is in use, it can only detect the external compressive resistance of tinplate cans, cannot perform high-pressure detection on the inside of tinplate cans, and cannot seal the tinplate cans in an open state conveniently. The installation and detection are rather cumbersome, and the tinplate cans cannot be fixed inside the detection device conveniently.

[0005] To achieve the above object, the present invention provides the following technical solution: A device for detecting the high-pressure resistance of a tinplate can, comprising a pressure detector. A detection groove is formed on the upper surface of the pressure detector. A sealing and fixing cover is movably installed inside the detection groove near the upper port. A fixing plate is fixedly installed on the lower surface of the sealing and fixing cover. An electric lifting column is fixedly installed inside the detection groove. The upper end surface of the electric lifting column is fixedly installed with a squeezing can. A threaded connection column is movably installed inside the squeezing can. A threaded lifting knob is movably sleeved on the surface of the threaded connection column. A threaded fixing column is movably installed inside the threaded lifting knob. A ventilation hole is formed on the outer surface of one side of the pressure detector.

[0006] Specifically, through the cooperation of the provided sealing and fixing cover and the pressure detector, the inside of the detection groove can be sealed. The tinplate can to be detected can be temporarily fixed on the lower surface of the sealing and fixing cover through the fixing plate provided on the lower surface of the sealing and fixing cover. After the sealing and fixing cover is tightened, its threaded connection column will enter the inside of the tinplate can, so that the tinplate can can be directly fixed inside the detection groove for detection. The position of the tinplate can can be adjusted through the threaded lifting knob. Subsequently, the electric lifting column is started to drive the squeezing can into the tinplate can to be detected, and the inside of tinplate cans of different sizes can be sealed.

[0007] Preferably, a control panel is embedded and installed on the front surface of the pressure detector. Displacement support wheels are fixedly installed on the lower surface of the pressure detector near the four corner edges. A transparent observation window is embedded and installed on the front surface of the pressure detector on one side of the control panel.

[0008] Specifically, the displacement support wheels can facilitate the movement of the pressure detector. The control panel can control the start and stop of the internal device. The transparent observation window can view the internal detection situation.

[0009] Preferably, three rubber bases are evenly and fixedly installed on the upper surface of the sealing and fixing cover near the four peripheral edges. A displacement handle is fixedly installed on the upper surface of the sealing and fixing cover near the center. A rubber sealing gasket is sleeved at the bottom of the sealing and fixing cover.

[0010] Specifically, the rubber bases can prevent the sealing and fixing cover from directly contacting the ground when it is removed. The displacement handle can drive the sealing and fixing cover to move. The rubber sealing gasket can ensure the sealing performance of the sealing and fixing cover, ensuring that there is no air leakage when the sealing and fixing cover is installed inside the detection groove.

[0011] Preferably, a return spring is fixedly installed on the outer surface of one side of the fixing plate. The other end of the return spring is fixedly connected to a clamping block. An anti-slip rubber pad is fixedly installed on the outer surface of the other side of the clamping block. A tinplate can is movably connected to the outer surface of the other side of the anti-slip rubber pad.

[0012] Specifically, the return spring can provide a certain thrust for the clamping block, and the clamping block is driven by the thrust to move the anti-skid rubber pad inward to fix the tinplate can relatively to the lower surface of the sealing fixed cover.

[0013] Preferably, a limiting groove is provided on the upper end surface of the squeeze tank, a connecting spring is fixedly installed inside the limiting groove, the other end of the connecting spring is fixedly connected to a threaded connecting column, the threaded connecting column is movably installed inside the squeeze tank through the limiting groove, an air intake pressure hole is provided on the upper end surface of the squeeze tank, and an internal connecting pipe is fixedly connected to the port position of the air intake pressure hole.

[0014] Specifically, the extrusion tank is set as a semi-conical device as a whole. During the upward movement, the larger the cross-section inside the tinplate can, the slower the upward movement can seal the inside of the tinplate can. The connecting spring can relatively fix the threaded connecting column and move it inside the limiting groove. Gas can be injected into the air inlet pressure hole through the internal connecting pipe, and the air inlet pressure hole can pressurize the inside of the tinplate can.

[0015] Preferably, a scale is embedded in the front surface of the threaded connecting column, a rubber pad is fixedly installed on the upper end surface of the threaded connecting column, threaded through holes are opened on the outer surfaces of both sides of the threaded lifting button, and the threaded fixing column is movably installed inside the threaded lifting button through the threaded through holes.

[0016] Specifically, the rubber pad can prevent the threaded connection column from damaging the bottom of the tinplate can when it contacts the tinplate can. The rotating threaded fixing column and the threaded through hole can cooperate with each other to fix the threaded lifting button on the surface of the threaded connection column, and the scale can more intuitively reflect the height of the threaded lifting button.

[0017] Preferably, a dustproof ventilation net is fixedly installed at the port position of the ventilation hole, a pressure controller is fixedly installed at the other end of the ventilation hole and inside the pressure detector, the other side outer surface of the pressure controller is fixedly connected to the internal connecting tube, an external connecting tube is fixedly installed below the internal connecting tube and on the outer surface of one side of the pressure controller, and the other end of the external connecting tube is connected to the interior of the detection groove.

[0018] Specifically, the dustproof ventilation net can prevent external dust from entering the ventilation hole. Starting the pressure controller can suck external air into the ventilation hole. The pressure controller pressurizes the air and transmits it to the external connecting pipe and the internal connecting pipe to perform pressurized testing on the detection groove and the inside of the tinplate can.

[0019] Preferably, a displacement sliding column is fixedly installed on the outer surface of the other end of the threaded fixing column. A limiting block is fixedly installed on the outer surface of the other end of the displacement sliding column. A sliding ring is sleeved on the surface of the displacement sliding column. A sealing ring connecting column is fixedly installed on the upper surface of the sliding ring. An elastic rubber sealing ring is fixedly connected to the lower end surface of the sealing ring connecting column.

[0020] Specifically, the surface of the displacement sliding column is smooth through the setting. The sliding ring on the surface of the sleeved displacement sliding column can slide freely. The limiting block prevents the sliding ring from sliding out of the surface of the displacement sliding column. The sliding ring is connected to the elastic rubber sealing ring through the sealing ring connecting column. The elastic rubber sealing ring is in contact with the inside of the tinplate can, and can cooperate with the extrusion can to relatively seal the inside of the tinplate can.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the cooperation of the sealing fixed cover and the clamping block, place the upper surface of the sealing fixed cover downward horizontally through the rubber base. Dial the clamping block on one side to place the tinplate can to be measured between the two clamping blocks. Due to the thrust provided by the return spring, the clamping block is driven by the thrust to drive the anti-slip rubber pad to move inward to relatively fix the tinplate can under the lower surface of the sealing fixed cover, and the fixation of the tinplate can can be completed without too much operation.

[0023] 2. Through the cooperation of the extrusion can and the threaded lifting knob, rotate the threaded lifting knob according to the height of the tinplate can to drive the threaded fixing column to move up and down on the surface of the threaded connecting column. The movement of the threaded fixing column can drive the elastic rubber sealing ring to move up and down. According to the internal depth of the tinplate can to be detected, it drops by one centimeter. At this time, slowly screw the sealing fixed cover into the detection groove, start the electric lifting column to drive the extrusion can to slowly move up. The extrusion can drives the threaded connecting column to slowly move up. During the slow upward movement, the rubber cushion block fixedly installed on the threaded connecting column will first contact the tinplate can, and the fixation of the tinplate can can be strengthened. At this time, the extrusion can continues to move up. Since the rubber cushion block is in contact with the tinplate can, the threaded connecting column will slowly retract into the limiting groove during the upward movement of the extrusion can. The extrusion can moves up. The whole extrusion can is a semi-conical device. During the upward movement, the cross-section in the tinplate can is larger. Continuing to move up will expand the elastic rubber sealing ring to contact the inside of the tinplate can, and relatively seal the inside of the tinplate can, and can conveniently seal tinplate cans of different sizes.

[0024] 3. By cooperating with the set extrusion tank and the pressure controller, starting the pressure controller can compress the external air into the internal connecting pipe, and the gas can be poured into the air inlet pressure hole through the internal connecting pipe. The air inlet pressure hole can pressurize the inside of the tinplate can, and the pressurized air can also be pressurized inside the detection groove through the external connecting pipe to detect the high-pressure performance of the outside of the tinplate can. The device can conveniently measure the internal and external high-pressure performance of the tinplate can, and the detection is more comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment 2

[0036] Such as Figures 1-7As shown, on the basis of the first embodiment, the present invention provides a technical solution: three rubber bases 202 are evenly fixedly installed on the upper surface of the sealing fixed cover 2 and near the edges of the four sides, a displacement handle 201 is fixedly installed on the upper surface of the sealing fixed cover 2 near the center position, a rubber sealing gasket 203 is sleeved on the bottom of the sealing fixed cover 2, a return spring 301 is fixedly installed on the outer surface of one side of the fixing plate 3, the other end of the return spring 301 is fixedly connected to a clamping block 302, and an anti-slip rubber is fixedly installed on the outer surface of the other side of the clamping block 302 Pad 303, the outer surface of the other side of the anti-slip rubber pad 303 is movably connected with a tinplate can 304, the upper end surface of the extrusion can 401 is provided with a limiting groove 402, and a connecting spring 403 is fixedly installed inside the limiting groove 402.

The extrusion tank 401 is a semi-conical device as a whole. During the upward movement, the larger the cross-section inside the tinplate can 304, the slower the upward movement can block the inside of the tinplate can 304. The connecting spring 403 can relatively fix the threaded connecting column 5 in the limiting groove 402 and move it. The gas can be injected into the air inlet pressure hole 404 through the internal connecting pipe 604, and the air inlet pressure hole 404 can pressurize the inside of the tinplate can 304. Example 3

[0038] like Figures 1-7 As shown, on the basis of Example 1 and Example 2, the present invention provides a technical solution: a scale 504 is embedded and installed on the front surface of the threaded connecting column 5, a rubber pad 501 is fixedly installed on the upper end surface of the threaded connecting column 5, threaded through holes 503 are opened on the outer surfaces of both sides of the threaded lifting button 502, and the threaded fixing column 7 is movably installed inside the threaded lifting button 502 through the threaded through holes 503.

[0039] In this embodiment, the rubber cushion block 501 can prevent the bottom of the tin can 304 from being damaged when the threaded connection column 5 contacts the tin can 304. By rotating the threaded fixing column 7 to cooperate with the threaded through hole 503, the threaded lifting knob 502 can be fixed on the surface of the threaded connection column 5, and the scale 504 can intuitively reflect the height of the threaded lifting knob 502. Embodiment 4

[0040] As Figures 1-7 shown, on the basis of Embodiment 1, Embodiment 2, and Embodiment 3, the present invention provides a technical solution: a dust-proof ventilation net 601 is fixedly installed at the port position of the ventilation hole 6, and a pressure controller 602 is fixedly installed at the other end of the ventilation hole 6 and inside the pressure detector 1. The outer surface of the other side of the pressure controller 602 is fixedly connected to the internal connecting pipe 604. Below the internal connecting pipe 604 and on the outer surface of one side of the pressure controller 602, an external connecting pipe 603 is fixedly installed. The other end of the external connecting pipe 603 communicates with the inside of the detection groove 104. The outer surface of the other end of the threaded fixing column 7 is fixedly installed with a displacement sliding column 701. The outer surface of the other end of the displacement sliding column 701 is fixedly installed with a limit block 702. A sliding ring 703 is sleeved on the surface of the displacement sliding column 701. A sealing ring connecting column 704 is fixedly installed on the upper surface of the sliding ring 703. The lower end surface of the sealing ring connecting column 704 is fixedly connected to an elastic rubber sealing ring 705.

[0041] In this embodiment, the dust-proof ventilation net 601 can prevent external dust from entering the ventilation hole 6. Starting the pressure controller 602 can suck external air into the ventilation hole 6, and through the pressurization of the pressure controller 602, it is respectively conveyed to the external connecting pipe 603 and the internal connecting pipe 604 to pressurize and detect the inside of the detection groove 104 and the tin can 304. The surface of the displacement sliding column 701 is smooth, and the sliding ring 703 sleeved on the surface of the displacement sliding column 701 can slide freely. The limit block 702 prevents the sliding ring 703 from sliding out of the surface of the displacement sliding column 701. The sliding ring 703 is connected to the elastic rubber sealing ring 705 through the sealing ring connecting column 704. The elastic rubber sealing ring 705 contacts the inside of the tin can 304 and can cooperate with the extrusion tank 401 to relatively seal the inside of the tin can 304.

[0042] The working principle and use process of the present invention are as follows: when using the device, the device needs to be placed in a suitable position, the sealing fixing cover 2 is unscrewed by the displacement handle 201, and the sealing fixing cover 2 is placed in a horizontal position with the upper surface facing downward through the rubber base 202, and the clamping block 302 on one side is moved to place the tinplate can 304 to be measured between the two clamping blocks 302. Due to the thrust provided by the return spring 301, the clamping block 302 is pushed to drive the anti-skid rubber pad 303 to move inward to fix the tinplate can 304 relatively to the lower surface of the sealing fixing cover 2, and the tinplate can 304 is completed. To fix the tinplate can 304, the threaded lifting button 502 is rotated according to the height of the tinplate can 304 to drive the threaded fixing column 7 to move up and down on the surface of the threaded connecting column 5. The movement of the threaded fixing column 7 can drive the elastic rubber sealing ring 705 to move up and down. The internal depth of the tinplate can 304 is detected to drop by 1-2CM as needed. At this time, the sealing fixing cover 2 is slowly screwed into the detection groove 104, and the electric lifting column 4 is started to drive the squeeze can 401 to move up slowly. The squeeze can 401 drives the threaded connecting column 5 to move up slowly. In the process of slowly moving up, The rubber pad 501 fixedly installed on the threaded connection column 5 of the process column will first contact the tinplate can 304, and the fixation of the tinplate can 304 can be reinforced. At this time, the squeeze can 401 continues to move upward, and the threaded fixing column 7 contacts the tinplate can 304 due to the rubber pad 501. At this time, the threaded connection column 5 will slowly retract into the limiting groove 402 during the upward movement of the squeeze can 401. The squeeze can 401 moves upward. The squeeze can 401 is a semi-conical device as a whole. During the upward movement, the larger the cross section inside the tinplate can 304, the larger the cross section inside the tinplate can 304. Continuing to move upward will cause the elastic rubber sealing ring 705 to expand and contact the inside of the tinplate can 304, making the inside of the tinplate can 304 relatively sealed. At this time, starting the pressure controller 602 can compress the external air into the internal connecting tube 604, and the gas can be poured into the air inlet pressure hole 404 through the internal connecting tube 604. The air inlet pressure hole 404 can pressurize the inside of the tinplate can 304, and the pressurized air can also be passed through the external connecting tube 603 to pressurize the inside of the detection groove 104 to detect the high-pressure performance of the outside of the tinplate can 304.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
