[0020] See also Figures 1 to 5 A flash removal device for a plastic barrel comprises a working frame 1, wherein a first mounting frame 201 and a second mounting frame 202 are respectively arranged on both sides of the working frame 1, a driving motor 102 is installed on the working frame 1, and a placing plate 2 is fixedly connected to the output end of the driving motor 102, a symmetrical cutting adjustment rod 203 is rotatably connected to the inside of the first mounting frame 201 through a rotating rod, a cutting knife 204 is movably connected to the inside of the cutting adjustment rod 203 through a rotating rod 209, threaded sleeves are sleeved at both ends of the rotating rod 209, and the threaded sleeves can limit the cutting knife 204 inside the cutting adjustment rod 203 and fix the rotation angle of the cutting knife 204, a symmetrical grinding adjustment rod 205 is rotatably connected to the inside of the second mounting frame 202 through a rotating rod, and a grinding belt 207 is arranged on the grinding adjustment rod 205, a gantry frame 103 is fixedly connected to one side of the working frame 1, a cylinder 3 is installed on the gantry frame 103, and a pressing plate 301 is rotatably connected to the output end of the cylinder 3.

[0021] Among them, the angle of the cutting knife 204 can be finely adjusted according to the arc angle of the edge of the plastic barrel, and then the cylinder 3 is started to control the pressing plate 301 to move downward and press on the middle part of the bottom wall of the plastic barrel, and the pressing block 305 is pressed on the edge of the middle part of the plastic barrel to complete the pressing process of the plastic barrel, and then the driving motor 102 is started to drive the placement plate 2 to rotate, and the placement plate 2 rotates to drive the plastic barrel to rotate, that is, the cutting knife 204 can be used to cut the burrs of the plastic barrel. After the burrs are removed, the sanding belt 207 on the sanding frame 206 is operated in the same way as the above-mentioned cutting knife 204 to complete the sanding process of the plastic barrel.

[0022] Among them, because the diameters of the bottom walls and top walls of different plastic barrels and the heights of the plastic barrels are different, and some plastic barrels are wide at the top and narrow at the bottom, by rotating the cutting adjustment rod 203 and moving the position of the first mounting frame 201 on the sliding frame 101, the cutting knife 204 on the cutting adjustment rod 203 can be made to fit better with the edge of the plastic barrel.

[0023] Preferably, both sides of the working frame 1 are fixedly connected with the sliding frame 101, the first mounting frame 201 and the second mounting frame 202 are slidably connected to the sliding frame 101, and a limit rod is provided at the connection.

[0024] Among them, the limiting rod is spirally connected to the first mounting frame 201 and the second mounting frame 202, and the height of the limiting rod is consistent with the sliding frame 101. By rotating the limiting rod, the first mounting frame 201 and the second mounting frame 202 can be tightly fitted on the sliding frame 101, thereby fixing the positions of the first mounting frame 201 and the second mounting frame 202 on the sliding frame 101.

[0025] Furthermore, the positions of the first mounting frame 201 and the second mounting frame 202 can be adjusted according to the diameter of the plastic barrel, so that plastic barrels of different sizes can be processed.

[0026] Preferably, the grinding adjustment rod 205 is movably connected to a grinding frame 206 via a rotating rod 209, and the grinding frame 206 is rotatably connected to two groups of rollers, and a sanding belt 207 is wound between the two groups of rollers.

[0027] Among them, threaded sleeves are sleeved on both ends of the rotating rod 209, and the threaded sleeves can limit the grinding frame 206 inside the grinding adjustment rod 205 and fix the rotation angle of the grinding frame 206. The set sanding belt 207 can grind the circumferential edge of the plastic barrel, and the position of the sanding belt 207 on the grinding frame 206 can be moved by rotating the roller to avoid excessive wear of the grinding belt 207, thereby failing to grind the circumferential edge of the plastic barrel normally.

[0028] Preferably, one end of the rotating rods on the first mounting bracket 201 and the second mounting bracket 202 are both sleeved with a limiting nut 208 .

[0029] Among them, the limiting nut 208 can fix the rotation angle of the rotating rod on the first mounting frame 201 and the second mounting frame 202, that is, fix the angle of the cutting adjustment rod 203 on the first mounting frame 201, and fix the angle of the grinding adjustment rod 205 on the second mounting frame 202.

[0030] Preferably, a plurality of mounting grooves 302 are formed on the pressing plate 301 , a pressing rod 304 is installed inside the mounting groove 302 via a torsion spring rod 303 , and a pressing block 305 is fixedly connected to one side of the pressing rod 304 .

[0031] When the pressing plate 301 moves downward, it presses on the middle of the bottom wall of the plastic barrel, and the pressing block 305 presses on the edge of the middle of the plastic barrel, thereby completing the pressing process on the plastic barrel.

[0032] Preferably, the pressing plate 301 is coaxially arranged with the placing plate 2 , and the pressing block 305 is higher than the pressing plate 301 .

[0033] Among them, when the pressing plate 301 presses the bottom of the plastic barrel again, the set pressing block 305 will first contact the bottom of the plastic barrel. When the pressing plate 301 contacts the bottom of the barrel, the pressing rod 304 on the pressing block 305 will deflect slightly, and pressure is applied to the pressing rod 304 through the torsion spring rod 303, so that the pressing block 305 presses the bottom of the barrel more tightly.

[0034] Working principle: Place the plastic barrel to be polished on the placement plate 2, and then adjust the first mounting frame 201 according to the diameter of the plastic barrel, so that the cutting knives 204 of the two sets of cutting adjustment rods 203 are respectively fitted with the upper edge and the lower edge of the plastic barrel, and the angle of the cutting knives 204 can be slightly adjusted according to the arc angle of the edge of the plastic barrel, and then start the cylinder 3 to control the pressing plate 301 to move downward and press on the middle of the bottom wall of the plastic barrel, and the pressing block 305 is pressed on the edge of the middle of the plastic barrel, so that the pressing process of the plastic barrel can be completed, and then Then start the drive motor 102 to drive the placement plate 2 to rotate. When the placement plate 2 rotates, the plastic barrel is also driven to rotate. The pressure applied by the cylinder 3 to the plastic barrel will not be greater than the torque of the drive motor 102 when it rotates, and will not affect the drive motor 102 from driving the plastic barrel to rotate through the placement plate 2. That is, the burrs of the plastic barrel can be cut by the cutting knife 204. After the burrs are removed, the position of the second mounting frame 202 is adjusted, and the sanding belt 207 on the sanding frame 206 is operated like the above-mentioned cutting knife 204 to complete the sanding process of the plastic barrel.
