Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrel processing, in particular to an inner wall polishing device. Background Art

[0002] Plastic barrels are mostly used for the storage and transportation of various liquids. They have good properties for the packaging of special hazardous materials. They are not easy to break, rust-proof, lightweight, and have excellent oil resistance and strong corrosion resistance. They are mostly used for the packaging of hazardous materials that require heat preservation, moisture resistance, pressure resistance, and corrosion resistance. After the production of plastic barrels is completed, the inner walls of some plastic barrels are not smooth enough to meet the requirements, so the inner walls of these plastic barrels need to be polished.

[0003] When the existing plastic barrel inner wall polishing device is used, it can usually only polish plastic barrels with vertical barrel walls. However, some plastic barrels have a small arc-shaped lower body, which is not suitable for the existing polishing device, reducing the practicality of the device. Utility Model Content

[0004] The purpose of the utility model is to provide an inner wall polishing device, which can polish the inner wall of a plastic barrel with a vertical barrel wall or a curved barrel wall, thereby improving the practicality of the device and solving the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inner wall polishing device, comprising a base, a protective box, a fixing mechanism and a control box, a protective box being installed on the upper surface of the base, a sleeve being installed in the middle, two fixing mechanisms being symmetrically installed on the upper surface of the base on the left and right sides of the sleeve, two lifting electric rods being symmetrically installed in the middle of the top of the protective box, four polishing rods being slidably installed around the two lifting electric rods, a mounting plate being jointly installed at the protruding ends of the two lifting electric rods and the lower ends of the four polishing rods, a polishing motor being installed in the middle of the top of the mounting plate, a circular shaft being connected to the output shaft of the polishing motor through a flange, four polishing rods being staggered and installed on the circular shaft, polishing brushes being installed at the ends of the four polishing rods, a fixing screw being spirally connected to the connection between the circular shaft and the two upper polishing rods, a stopper being installed on the two lower polishing rods, and a spring being fitted on the inner side of the stopper.

[0006] Preferably, four footings are installed in a rectangular array at the four corners of the bottom of the base. By providing the four footings, the base can be stably supported.

[0007] Preferably, the front hinge of the protection box is rotatably provided with two box doors. By providing the two box doors, it is convenient for plastic barrels to enter and exit the protection box.

[0008] Preferably, the fixing mechanism is composed of a support base, a fixed electric rod, a round rod, and an arc-shaped clamping base. The fixed electric rod is mounted on the outer side of the upper end of the support base, and two round rods are symmetrically mounted above and below the fixed electric rod for sliding. The arc-shaped clamping base is mounted on the protruding end of the fixed electric rod and one end of the inner side of the two round rods. By setting up the fixing mechanism, the plastic barrel can be fixed.

[0009] Preferably, the control box is installed on the right side of the protection box, and the control box is electrically connected to the fixed electric rod, the lifting electric rod and the polishing motor respectively. By setting the control box, it is convenient to control the polishing work of the inner wall of the plastic barrel as a whole.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] When the utility model polishes a plastic barrel, after the plastic barrel is fixed, two lifting electric rods and a polishing motor are started through a control box. The two lifting electric rods drive four polishing brushes to enter the plastic barrel. The polishing motor drives the circular shaft to rotate through the flange. The rotation of the circular shaft drives the four polishing brushes to rotate to polish the inner wall of the plastic barrel. The distance between the two polishing brushes at the upper end can be adjusted by a fixing screw, and the two polishing brushes at the lower end are retractable under the action of a spring, so that the inner wall of a plastic barrel with a vertical barrel wall can be polished as well as the inner wall of a plastic barrel with an arc-shaped barrel wall, thereby improving the practicality of the device.
