[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] A flash removal device for polyethylene chemical barrels, such as Figure 1-Figure 5 As shown, it includes: a workbench 1 and a mounting frame 2, the mounting frame 2 is installed on the workbench 1, a groove 100 is opened on the workbench 1, and also includes a guide frame 3, a guide wheel 4, a reset spring a5, a cutting knife 6, a clamping plate 7, a roller 8, a reset spring b9, a support frame 10, a limit platform 11 and a blade 12, the guide frame 3 is slidably connected to the front side of the mounting frame 2, the guide wheel 4 is rotatably connected to the top and bottom of the guide frame 3, a reset spring a5 is arranged between the guide frame 3 and the mounting frame 2, the cutting knife 6 is connected to the front edge of the mounting frame 2, and the cutting knife 6 extends toward the guide wheel 4, the clamping plates 7 are symmetrically slidably connected to the left and right sides of the mounting frame 2, the rollers 8 are rotatably connected to the clamping plates 7 at intervals, a reset spring b9 is arranged between the clamping plates 7 and the mounting frame 2, the left and right edges of the middle part of the workbench 1 are connected to the support frame 10, the top of the support frame 10 is commonly connected to the limit platform 11, and the limit platform 11 is provided with a blade 12.

[0029] The clamping plate 7 is designed to be arc-shaped and can fit the body of the chemical barrel 200.

[0030] When using the device, the chemical barrel body 200 that needs to be deburred is placed on the workbench 1. When placing it, the top cover of the chemical barrel body 200 needs to contact the surface of the workbench 1, and then the chemical barrel body 200 is pushed. When the chemical barrel body 200 moves to contact the limiting platform 11, the chemical barrel body 200 is rotated so that the solidified long strips of residual material at the bottom of the barrel can enter the blade 12 in the limiting platform 11. Continuing to push the chemical barrel body 200 will make the barrel body contact with the clamping plate 7. At this time, the clamping plates 7 on the left and right sides of the mounting frame 2 will move outward under the squeezing of the chemical barrel body 200. Since the clamping plates 7 are provided with rollers 8, the chemical barrel body 200 can easily move under the clamping of the clamping plates 7. At the same time, the clamping plates 7 will squeeze the reset spring b9 when moving outward. At the same time, the long strips of residual material entering the blade 12 of the limiting platform 11 will gradually contact the blade 12 as the chemical barrel body 200 moves. When contacting the blade 12, the long strips of residual material will be cut off. Continuing to push the chemical barrel body 200 will cause it to contact the guide wheel 4 on the guide frame 3. Continuing to push the chemical barrel body 200 will cause the guide frame 3 to move forward and cause the top cover of the chemical barrel body 200 to contact the cutting knife 6, and the return spring a5 between the guide frame 3 and the mounting frame 2 will also be squeezed. Since the clamping plate 7 is designed in an arc shape, when the top cover of the chemical barrel body 200 contacts the cutting knife 6, only the edge of the clamping plate 7 can contact the barrel body of the chemical barrel body 200, thereby clamping and fixing the chemical barrel body 200 on the front side of the mounting frame 2 near the cutting knife 6, and then start to rotate the chemical barrel body 200. Since the barrel body of the chemical barrel body 200 has already contacted the guide wheel 4, it will not encounter too much resistance during rotation. During rotation, the cutting knife 6 will gradually cut off the top cover of the chemical barrel body 200. At this time, the chemical barrel body 200 with the flash removed can be removed, thereby achieving the effect of being able to smoothly cut off the top cover and long strips of excess material of the chemical barrel body 200.

[0031] like Figure 6 As shown, it also includes a sliding frame 13, a push plate 14, a guide wheel 141, a push-pull handle 15 and an L-shaped limit column 16. A slide groove is opened in the groove 100 on the workbench 1, and the sliding frame 13 slides in the slide groove. Push plates 14 are connected to the sliding frame 13 from top to bottom at intervals, and guide wheels 141 are connected to the push plate 14 to rotate at intervals. The sliding frame 13 is connected to the push-pull handle 15, and an L-shaped limit column 16 is connected to the left edge of the rear side of the workbench 1. The L-shaped limit column 16 can squeeze the bottom of the chemical barrel body 200 pushed by the push plate 14.

[0032] The push plate 14 is designed to be arc-shaped and can fit the body of the chemical barrel 200.

[0033] Since the push plate 14 is designed to be arc-shaped, there is no need to spend extra time to align it with the groove 100 when placing the chemical barrel. When the chemical barrel body 200 is placed on the workbench 1, the arc-shaped push plate 14 can fit the barrel body, and also can make the chemical barrel body 200 directly align with the groove 100. At the same time, since the push plate 14 is provided with a guide wheel 141, it can avoid the push plate 14 from directly contacting the chemical barrel body 200 to prevent damage to the barrel body. At this time, the sliding frame 13 can slide in the sliding groove by pushing and pulling the handle 15. When the sliding frame 13 moves, the push plate 14 will support the chemical barrel body 200 through the guide wheel 141, so that the chemical barrel body 200 can move at the same time. When the long strip of residual material on the bottom of the chemical barrel body 200 contacts the L-shaped limit column 16, the chemical barrel body 200 will rotate, so that the long strip of residual material can be perpendicular to the L-shaped limit column 16, thereby achieving the effect of being able to automatically correct and enter the limit platform 11.

[0034] like Figure 7 and Figure 8 As shown, it also includes a servo motor a17, a worm 18, a transmission rod 19, a conveying device 20, a power rod 21, a servo motor b211 and a gear set. The servo motor a17 is installed on the left front side of the top of the workbench 1, and the worm 18 is connected to the output shaft of the servo motor a17 through a coupling. A transmission rod 19 is installed on the left side of the mounting frame 2, and the bottom of the transmission rod 19 is connected to the worm 18. Conveying devices 20 are installed on both sides of the mounting frame 2. The conveying device 20 on the left side of the mounting frame 2 is connected to the top of the transmission rod 19. The power rod 21 is connected to the conveying device 20 on the right side of the mounting frame 2, and the power rod 21 penetrates to the bottom of the workbench 1. A servo motor b211 is installed on the bottom right side of the workbench 1, and the servo motor b211 corresponds to the power rod 21. The output shaft of the servo motor b211 is connected to the power rod 21 through a gear set.

[0035] The transmission rod 19 is composed of a rotating rod, a sprocket wheel, a transmission chain and a worm gear a. The right side of the mounting frame 2 is rotatably connected to the rotating rod, the bottom key of the rotating rod is connected to the worm gear, the worm gear a is meshed with the worm 18, the top of the rotating rod is connected to the sprocket wheel, the conveying device 20 on the left side of the mounting frame 2 is connected to the sprocket wheel, and a transmission chain is wound between the rotating rod and the sprocket wheel on the conveying device 20 on the left side of the mounting frame 2.

[0036] The conveying device 20 is composed of a pulley and a transmission belt. The left and right sides of the mounting frame 2 are symmetrically and rotatably connected with pulleys, and a transmission belt is respectively wound between the pulleys on the left and right sides. A chain wheel is connected to the top of the pulley on the left, and a power rod 21 is connected to the pulley on the right.

[0037] The gear set consists of a bevel gear a212 and a bevel gear b213. The output shaft of the servo motor b211 is connected to the bevel gear a212 via a coupling. The bottom end of the power rod 21 is connected to the bevel gear b213. The bevel gear a212 and the bevel gear b213 are meshed.

[0038] When the servo motor a17 is running, the worm 18 will be rotated. When the worm 18 rotates, it will drive the rotating rod to rotate through the worm gear a meshing with it. When the rotating rod rotates, it will provide power to the pulley and transmission belt on the left through the sprocket wheel and the transmission chain on its top. At the same time, when the servo motor b211 is running, the bevel gear a212 will rotate. Since the bevel gear a212 is meshing with the bevel gear b213, the power rod 21 will also rotate together. At the same time, the power rod 21 will also drive the pulley on the right to rotate, thereby providing power to the pulley and transmission belt on the right. When the push plate 14 pushes the chemical barrel body 200 to contact the transmission belt, the transmission belts on the left and right sides will transport the chemical barrel body 200 to the cutting knife 6 on the mounting frame 2, thereby achieving the effect of not requiring manual pushing.

[0039] like Fig. 9 As shown, it also includes a rotating rod 22, a guide roller 221, a Z-shaped connecting rod 23, a worm gear b231, a connecting wheel 232, a sliding frame 24, an extrusion block 241 and a tension spring 25. The servo motor a17 is installed at the top of the workbench 1 and is connected to the rotating rod 22 at the corresponding rotation. The top and bottom of the rotating rod 22 are connected to the guide roller 221. The key on the rotating rod 22 is connected to the worm gear b231. The worm gear b231 is in contact with the Z-shaped connecting rod 23. The connecting wheels 232 are installed on the upper and lower sides of the worm gear a. The connecting wheel 232 is connected to the worm gear a. The connecting wheel 232 A sliding groove 131 is provided on it for rotating the worm gear a. When the worm gear a rotates, it will not drive the connecting wheel 232 to rotate. One end of the Z-shaped connecting rod 23 is slidably connected to the connecting wheel 232 on the rotating rod, and the other end is slidably connected to the rotating rod 22. The end of the Z-shaped connecting rod 23 is in contact with the worm gear b231. A sliding frame 24 is slidably connected inside the workbench 1. One end of the sliding frame 24 extends toward the direction of the worm gear a and is connected to the connecting wheel 232, and the other end extends toward the guide roller 221 and is connected to the extrusion block 241. A tension spring 25 is provided between the sliding frame 24 and the inside of the workbench 1.

[0040] When the chemical barrel body 200 is conveyed to the cutting knife 6 on the mounting frame 2, the chemical barrel body 200 will squeeze the squeezing block 241. When the squeezing block 241 is squeezed, it will be pressed down in the workbench 1, thereby pressing down the sliding frame 24 connected to the squeezing block 241. When the sliding frame 24 is pressed down, the connecting wheel 232 connected to it will cause the worm gear a key-connected to the rotating rod to slide down and no longer mesh with the worm 18. At this time, the rotating rod no longer rotates, and the pulley and transmission belt on the left will also lose power. At the same time, when the sliding frame 24 is pressed down, the Z-shaped connecting rod 23 will cause the worm gear b231 in contact with it to descend, and the worm gear b231 will mesh with the worm 18 when it descends, thereby causing the guide roller 221 on the rotating rod 22 to rotate. At this time, the guide roller 221 and the conveying belt on the right can cause the chemical barrel body 200 to rotate, thereby achieving the effect of cutting off the top cover without manually rotating the chemical barrel body 200.

[0041] like Figure 1 As shown, the workbench 1 also includes balls 26 , and the balls 26 are evenly distributed on the workbench 1 .

[0042] The ball bearings 26 can reduce the friction between the chemical barrel body 200 and the workbench 1, thereby enabling the chemical barrel body 200 to move better.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
