Description

Technical Field

[0001] The utility model relates to the technical field of plastic container barrels, in particular to a thickness detection device for plastic container barrels. Background Art

[0002] Plastic container barrels are containers made of plastic materials such as high-density polyethylene or polypropylene. They have the characteristics of large capacity, light weight, corrosion resistance, and good sealing performance. Therefore, they are widely used in many industries. Plastic container barrels are mostly made of plastics such as polyethylene or polypropylene through blow molding or injection molding. They have excellent corrosion resistance and weather resistance. They are cylindrical in shape, with two outlets at the bottom and a lid on the top. In order to ensure the load-bearing capacity, durability, sealing of plastic container barrels and safety during transportation, it is necessary to use a detection device to detect the thickness of plastic container barrels.

[0003] Common plastic container barrel thickness detection devices are usually composed of a support frame, a measuring ruler, a fixed block, and a sliding block. First, move the measuring ruler installed on the support frame to the top of the plastic container barrel, first fit the fixed block on the measuring ruler to the inner wall of the plastic container barrel, then drag the sliding block on the surface of the measuring ruler to move and fit it to the outer wall of the plastic container barrel. The distance between the fixed block and the sliding block is the thickness of the plastic container barrel, and the thickness data is obtained from the scale line on the measuring ruler.

[0004] The traditional plastic container barrel thickness detection device first moves the device to the top of the plastic container barrel, and then adjusts the detection structure on the device to detect the thickness of the plastic container barrel. This process cannot directly connect the device to the plastic container barrel, making it impossible to ensure the stability of the device at the top of the plastic container barrel. It is not only inconvenient to operate, but also impossible to determine the accuracy of the detection data. In order to solve the above problems, some plastic container barrel thickness detection devices set up a support frame, install the device on the support frame, move the support frame to make the device reach the top of the plastic container barrel, and then adjust the detection structure on the device to ensure the stability of the device. However, in this way, the support frame and the device are connected by bolts, and the orientation of the device cannot be adjusted on the support frame, so that the plastic container barrel cannot be fully tested for thickness. For this reason, a plastic container barrel thickness detection device is proposed. Utility Model Content

When it is necessary to detect another area of ​​the plastic container barrel, the first driving motor drives the measuring column to rotate at the top center of the plastic container barrel, so that the fixed block and other structures are moved to another area of ​​the plastic container barrel for detection. On the one hand, the rotary design can not only adjust the position of the detection structure to detect another area of ​​the plastic container barrel, but also perform a comprehensive detection of the plastic container barrel; on the other hand, the counterweight block and the self-locking universal wheel on the moving seat can ensure the stability of the measuring column during position movement and use.

[0012] Preferably, the sliding ring is designed in the shape of a U-shaped letter "U", and a sleeve is installed at the center of the bottom of the sliding ring, and fixed sockets are evenly opened on the outside of the sleeve.

[0013] Preferably, a lifting column is vertically inserted into the inner cavity of the sleeve, and a fixed plug rod is inserted and connected to the upper outer side of the lifting column and corresponds to the fixed plug hole, and the bottom of the lifting column is connected to the fixed block. When the use height of the fixed block needs to be adjusted, the fixed plug rod can be pulled out from the sleeve and the lifting column first, and then the lifting column is lowered to a certain height along the inner cavity of the sleeve, and then the fixed plug rod is inserted into the sleeve and the lifting column for connection, so that the thickness of the plastic container barrel at different heights can be detected within a certain range, avoiding the occurrence of uneven thickness of the plastic container barrel.

[0014] Preferably, a second drive motor is installed at the center of the outer side of the measuring column, and a positioning slot is provided at the center of the bottom of the measuring column. The second drive motor can drive the corresponding structure on the measuring column to rotate.

[0015] Preferably, a bidirectional lead screw is transversely arranged at the center of the inner cavity of the measuring column and is coaxially connected to the second drive motor, and sliding blocks are sleeved on both sides of the surface of the bidirectional lead screw. The second drive motor drives the bidirectional lead screw to rotate in the inner cavity of the measuring column, and the sliding block drives the corresponding structure to move according to the direction of the bidirectional lead screw.

[0016] Preferably, a positioning slide is connected to the bottom center of the sliding block, and the positioning slide is located in the inner cavity of the positioning slot, and the positioning slide is connected to the sliding ring. The sliding block can drive the sliding ring to move along the positioning slot through the positioning slide, which can, on the one hand, enable the thickness detection structure to be operated automatically; on the other hand, the sliding block and the positioning slot can limit the sliding block to prevent the sliding block and the bidirectional lead screw from rotating in the same direction.
