[0002] Plastic barrels are made of high-density polyethylene raw materials and are heat-insulating, moisture-proof, pressure-resistant, and corrosion-resistant dangerous goods storage barrels. They have the characteristics of high rigidity, light weight, wear resistance, and durability. They are widely used in the field of industrial production. Plastic barrels are prone to air eye defects during the blow molding process. Therefore, it is necessary to conduct air tightness testing on plastic barrels to screen out plastic barrels with air eye defects to prevent them from entering the market.
[0003] During the production and use of plastic barrels, it is often necessary to detect whether there is side leakage to prevent the liquid from flowing out. Currently, manual observation is mainly used to understand whether there is side leakage in plastic barrels, but this method can only detect larger holes, and is time-consuming and labor-intensive, with poor detection effect. Utility Model Content

[0005] Furthermore, the moving component includes a linear module installed on the frame, and the moving end of the linear module is fixed with a moving plate slidably connected to the top of the frame, and the top of the moving plate is provided with multiple downward pressure cylinders and multiple guide rods, and the bottom of the multiple guide rods is fixed with a downward pressure plate fixed to the top end of the downward pressure cylinder, and the downward pressure plate is concave in shape, and the sealing plate is fixed on the concave surface of the downward pressure plate.

[0007] Furthermore, two relatively distributed clamping cylinders are installed at the bottom of the lower moving plate, and a shifting block slidably connected to the lower moving plate is fixed to the ejection end of the clamping cylinder, and a clamping plate is fixed to one side of the shifting block.
[0008] Furthermore, an upper top assembly located below the placing table is installed on the operating table, and the upper top assembly includes a lifting cylinder and multiple guide columns installed on the operating table, a lifting plate connected to the guide columns is fixed to the ejection end of the lifting cylinder, a push plate is fixed between the tops of the multiple guide columns, and a top block that can extend to the top of the concave table is fixed to the top of the push plate.
[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0010] The detection device for the plastic barrel can clamp the plastic barrel on the conveying device and transfer it to the concave platform through the cooperation of the moving component and the clamping component, and then clamp the barrel body through the downward pressing and upward pushing components, so that the barrel mouth and the annular rubber ring are tightly attached, which can effectively avoid leakage during gas injection, and then until the sealing plate seals the through hole on the lower plate, and at the same time drives the air guide head to be located in the barrel body to complete the inflation operation.

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3In this embodiment, a detection device for a plastic barrel includes an operating table 1 and a frame 2 and a placement table 702 installed on the operating table 1. A concave table 703 is fixed on the top of the placement table 702, and the inner diameter of the concave table 703 is adapted to the barrel body. A loading component is installed on the frame 2, and the loading component includes a moving component 3 installed on the top of the frame 2, and a sealing plate 5 and a lower plate 401 distributed opposite to the sealing plate 5 are installed at the moving end of the moving component 3. A clamping component 4 and an annular rubber ring 402 located between the clamping components 4 are installed at the bottom of the lower plate 401. A through hole is opened on the lower plate 401, and an air guide head 6 perpendicular to the concave table 703 and capable of passing through the through hole is installed at the bottom of the sealing plate 5.
[0017] In the above structure, the moving component can drive the clamping component to be located above the loading point, and then the downward movement and the clamping component can move the plastic barrel from the conveying device to the concave platform for placement, and the downward movement can complete the downward pressure on the plastic barrel. At this time, the annular rubber ring will be tightly attached to the barrel mouth until the sealing plate is pressed down to seal the through hole, and then the air guide head passes through the through hole and the downward plate and is located in the barrel body, and then gas is injected into the inside. When the pressure of the injected gas changes, it can be judged that there is a leak. When there is no change within a certain period of time, it can be judged that there is no leak, and the inspection of the barrel body is completed. Through the operation of the loading component, it can be removed for the next set of operations, thereby realizing automated inspection of the barrel body and improving efficiency and quality.
[0018] like Figure 2 In the direction shown, the moving component 3 includes a linear module 301 installed on the top right side of the frame 2, and the moving end of the linear module 301 is fixed with a moving plate 302 which is slidably connected to the top of the frame 2, and two downward pressing cylinders 303 and four guide rods 304 are installed on the top of the moving plate 302, and a downward pressing plate 305 fixed to the ejection end of the downward pressing cylinder 303 is fixed between the bottoms of the four guide rods 304, and the downward pressing plate 305 is concave in shape, and the sealing plate 5 is fixed on the concave surface of the downward pressing plate 305, and the bottom of the sealing plate 5 and the bottom of the downward pressing plate 305 are not on the same horizontal plane. The linear module can drive the moving plate to move, so that the clamping assembly can be located above the external conveying device and the concave platform. When located above it, the downward pressure cylinder pushes the lower pressure plate downward, so that the clamping assembly can be driven close to the barrel body to complete the clamping and transfer it to the concave platform. When located on the concave platform, the barrel body can be pressed down and fixed by moving the lower pressure plate downward, so that the barrel mouth and the annular rubber ring are placed tightly to prevent leakage.
[0019] The bottom of the lower pressure plate 305 is sleeved with two sleeves 306, and the outer side of the sleeve 306 is sleeved with a spring 307. The top of the lower plate 401 is fixedly connected to the sleeve 306, and the spring 5307 is located between the lower pressure plate 305 and the lower plate 401. When the lower pressure plate drives the lower plate to move downward, when the lower plate presses the barrel, the lower plate pushes the sleeve upward, thereby squeezing the spring, so that it can play a buffering role until the sealing plate stops sealing the through hole, and then cooperates with the elastic force of the spring to improve the firmness of the downward pressure.
[0020] In addition, two relatively distributed clamping cylinders 403 are installed at the bottom of the lower moving plate 401, and a moving block 404 slidably connected to the lower moving plate 401 is fixed to the ejection end of the clamping cylinder 403, and a clamping plate 405 is fixed to the opposite side of the two moving blocks 404. When the moving device drives the lower moving plate to contact the barrel body, the moving block is driven to move by the clamping cylinder, and the barrel body can be clamped and fixed by the two clamping blocks, and the barrel body is transplanted in cooperation with the moving device.
[0021] like Figure 3 In the direction shown, the operating table 1 is installed with an upper assembly 7 located below the placing table 702. The upper assembly 7 includes a lifting cylinder 704 installed on the operating table 1 and four guide columns 706 sleeved thereon. A lifting plate 705 connected to the guide columns 706 is fixed to the ejection end of the lifting cylinder 704. A push plate 707 is fixed between the tops of the four guide columns 706. A top block 708 extending to the top of the concave platform 703 is fixed to the top of the push plate 707. While the moving assembly is pressed down for positioning, the lifting cylinder drives the lifting plate to move, and then the push plate is driven to push up by pushing the guide columns until the top block contacts the bottom of the barrel body, thereby improving the positioning of the barrel body, and also enabling the strength test of the bottom of the barrel body after the leakage is detected.
[0022] The working principle of the above embodiment is:
[0023] First, the external conveying device will convey the barrel to the appropriate position, and then the linear module will drive the moving plate to move until the lower plate is located above the barrel, and the downward pressure cylinder will drive the lower pressure plate to move downward until the annular rubber ring is in contact with the top of the barrel, and the clamping cylinder will drive the clamping plate to clamp the barrel through the shifting block, and then the barrel can be moved to the top of the concave platform with the cooperation of the moving assembly, and then the downward pressure cylinder will continue to press down, so that the annular rubber ring will tightly fit the top of the barrel to improve the sealing during detection, and the lower pressure plate will continue to press down through the lower plate to drive the sleeve column to push up, and at the same time The spring is squeezed until the sealing plate seals the through hole. At this time, the air guide head is also located in the barrel body. At this time, the lifting cylinder will also drive the lifting plate to move up, and then drive the push block to push up through the guide column until the top block and the bottom of the barrel body are on top. Therefore, the firmness of the barrel body can be improved, and then gas is injected through the air guide head. When the pressure drops, it is judged that there is a leakage point. When the gas is injected to a certain amount and the pressure does not drop for a certain period of time, it is judged that there is no leakage point. Through the cooperation of the moving assembly and the clamping assembly, automatic loading and unloading can be completed.
[0024] At the same time, after the leakage detection of the barrel body is completed, the upper push assembly continues to push up, and the force at the top block can be detected to test the strength of the barrel body.
[0025] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
