DETAILED DESCRIPTION

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] A burr removal device for plastic container production and processing, such as Figure 1-Figure 5 As shown, it includes a base plate 1, a mounting frame 2, a cylinder 3, a mounting plate 4, a grinding mechanism and a collecting mechanism. The mounting frame 2 is connected to the middle of the rear side of the base plate 1, the cylinder 3 is installed on the top front side of the mounting frame 2, the mounting plate 4 is connected to the telescopic rod of the cylinder 3, and the mounting plate 4 is provided with a grinding mechanism for grinding the opening of the plastic container and a collecting mechanism for collecting burrs during the grinding process.

[0032] like Figure 2 and Figure 3 As shown, the grinding mechanism includes a driving motor 51, a rotating ring 52, a guide frame 521, an electric guide rail 53, a connecting plate 531, a shell 54, a servo motor 55 and a grinding wheel 56. The driving motor 51 is embedded in the middle of the bottom of the mounting plate 4, and the output shaft of the driving motor 51 is connected to the rotating ring 52. The bottom of the rotating ring 52 is connected to the guide frame 521. The electric guide rails 53 are installed on both sides of the guide frame 521. A connecting plate 531 is connected between the two electric guide rails 53. The moving bodies of the two electric guide rails 53 are connected to the shell 54 so that the electric guide rails 53 can drive the shell 54 to move. The shell 54 is inclined and a servo motor 55 is installed in the shell 54. The output shaft of the servo motor 55 is connected to a grinding wheel 56 for grinding plastic containers.

[0033] like Figure 4 and Figure 5As shown, the collecting mechanism includes a guide sleeve 61, a soft collecting shell 62, an extension sleeve 63 and a fixing assembly. The guide sleeve 61 is rotatably connected to the middle of the bottom of the mounting plate 4. The guide sleeve 61 passes through the connecting plate 531 and is rotatably connected to the connecting plate 531. A plurality of ventilation holes are evenly spaced apart on the guide sleeve 61. The bottom of the guide sleeve 61 is connected to an extension sleeve 63. The extension sleeve 63 is connected to a soft collecting shell 62. The soft collecting shell 62 can move downward and enter into the plastic container, so that the debris generated during the grinding of the inner edge of the plastic container will enter into the soft collecting shell 62. A fixing assembly is provided between the soft collecting shell 62 and the mounting plate 4.

[0034] like Figure 6 and Figure 7 As shown, the fixing assembly includes an air pump 641, a connecting pipe 642 and an air bag 643. The air pump 641 is installed at the bottom of the mounting plate 4. The air outlet end of the air pump 641 is connected to the connecting pipe 642. A plurality of air bags 643 are evenly spaced along the circumferential direction at the lower outer side of the soft collection shell 62. The connecting pipe 642 passes through the guide sleeve 61 and the soft collection shell 62 and is connected to the air bag 643, so that the air pump 641 can be operated to inject air into the air bag 643 through the connecting pipe 642, so that the air bag 643 expands and presses against the inner wall of the plastic container to fix the soft collection shell 62 and the plastic container.

[0035] When it is necessary to remove burrs on the edge of the opening of a plastic container during production, the device can be used. When in use, the plastic container is first placed in the middle position of the bottom plate 1 so that the plastic container is located below the swivel 52. Then, the telescopic rod of the cylinder 3 can be controlled to extend to drive the mounting plate 4 to move downward. When the mounting plate 4 moves downward, the swivel 52 and the soft collection shell 62 can be driven downward. When the swivel 52 moves downward, it can drive the grinding wheel 56. After the grinding wheel 56 on the left side moves downward, it can abut against the inner wall of the opening of the plastic container. After the grinding wheel 56 on the right side moves downward, it can abut against the outer wall of the opening of the plastic container. After moving downward, the soft collection shell 62 can move into the interior of the plastic container. At this time, the air pump 641 can be controlled to operate through the connecting pipe 642 to expand the air bag 643 to abut against the inner wall of the plastic container, thereby fixing the plastic container to prevent the plastic container from rotating. When the soft collection shell 62 moves, the gas in the plastic container can enter the guide sleeve 61 and be discharged through the vent. At this time, the servo motor 55 can be controlled to drive the grinding wheel 56. The rotating ring 52 is rotated, and the rotating ring 52 is controlled to drive the grinding wheel 56 to move together when rotating, so that the grinding wheel 56 rotates while moving, and the opening position of the plastic container is polished. During the polishing process, the burrs on the outside of the opening edge will fall outside, and the burrs on the inside of the opening edge will fall into the soft collecting shell 62, so that the burrs are collected by the soft collecting shell 62. After the polishing is completed, the telescopic rod of the cylinder 3 is controlled to retract. At this time, the soft collecting shell 62 also moves upward and out. In this way, the device can be used to polish the opening of the plastic container, and the debris in the polishing process will fall into the soft collecting container instead of falling into the plastic container. There is no need to manually dump the impurities in the plastic container separately, which is more convenient to operate. In the actual polishing process, when the grinding wheel 56 moves down to the opening of the plastic container, the electric guide rail 53 can be controlled to drive the shell 54 to move and adjust until the two grinding wheels 56 move to the inner and outer sides of the opening of the plastic container respectively.

[0036] like Figure 8 As shown, it also includes a limiting mechanism, which includes a sliding frame 71, a screw 72, a connecting sleeve 73 and a limiting shaft 74. The left and right sides of the guide frame 521 are slidably connected to the sliding frame 71, and the connecting sleeve 73 is connected to the sliding frame 71. The outer shells 54 on both sides are rotatably connected with the screw 72. The screw 72 and the connecting sleeve 73 are threadedly matched, so that the rotation of the screw 72 can drive the connecting sleeve 73 to move through the thread, thereby adjusting the position of the sliding frame 71. The front and rear sides of the lower part of the sliding frame 71 are connected to the limiting shaft 74.

[0037] When the grinding wheel 56 moves to contact the opening position of the plastic container, the grinding wheel 56 on the left side is against the inner wall of the opening. At this time, the left screw rod 72 can be rotated to drive the left connecting sleeve 73 to move to the left, so that the left limiting shaft 74 moves to the outside of the plastic container opening, while the grinding wheel 56 on the right side is against the outer wall of the opening. At this time, the right screw rod 72 can be rotated to drive the right limiting shaft 74 to move to the inner wall of the plastic container opening. Subsequently, during the grinding process, the limiting shaft 74 can be against the plastic container, thereby supporting the grinding position of the plastic container and ensuring stability during grinding.

[0038] like Fig. 9 As shown, a feeding mechanism is also included, and the feeding mechanism includes a support frame 80, a belt drive group 81 and a stepper motor 82. The top of the base plate 1 is connected to the support frame 80, and the belt drive group 81 is installed on the support frame 80. The plastic container can be placed on the belt drive group 81. The support frame 80 can support the inside of the belt of the belt drive group 81. The stepper motor 82 is installed on the support frame 80, and the output shaft of the stepper motor 82 is connected to the transmission shaft of the belt drive group 81, so that the stepper motor 82 can drive the belt drive group 81 to rotate to transport the plastic container.

[0039] When placing plastic containers, the plastic containers can be placed on the belt drive group 81, and the stepper motor 82 is used to drive the belt drive group 81 to rotate intermittently to achieve intermittent transportation of the plastic containers. When the belt drive group 81 stops, the burrs at the opening of the plastic container can be removed to achieve the effect of automatically conveying the plastic containers.

[0040] like Fig.10 and Fig.11 As shown, a guiding mechanism is also included, and the guiding mechanism includes a side frame 91, a limiting frame 92, an electric push rod 93 and a roller 94. The middle of the front and rear sides of the support frame 80 are connected to the side frames 91, and the upper parts of the two side frames 91 are slidably connected to the limiting frames 92. Electric push rods 93 are installed on the two side frames 91. The telescopic rods of the electric push rods 93 are connected to the limiting frames 92 so that the electric push rods 93 can drive the limiting frames 92 to move. The limiting frames 92 are evenly spaced and rotatably connected with rollers 94 to reduce the friction of the plastic container when it moves. The right side of the limiting frame 92 is bent outward so that the plastic container can be guided by the limiting frame 92 when it moves.

[0041] When the plastic container moves, it can move between the two limit frames 92. When moving, the position where the right side of the limit frame 92 is bent outward can guide the plastic container, so that the front and rear positions of the plastic container can be limited by the limit frame 92. When the position of the limit frame 92 needs to be adjusted, the electric push rod 93 can be controlled to extend and retract to drive the limit frame 92 to move for adjustment.

[0042] like Fig.12 and Fig.13 As shown, it also includes an elastic rubber sleeve 101, an electric slide rail 102 and a connecting ring 103. The upper inner edge of the soft collection shell 62 is connected with the elastic rubber sleeve 101, the electric slide rail 102 is installed on the guide sleeve 61, the middle of the elastic rubber sleeve 101 is connected with a connecting ring 103, and the moving body of the electric slide rail 102 is connected to the connecting ring 103.

[0043] During the burr removal process, the debris will fall on the elastic rubber sleeve 101. When a lot of debris is accumulated in the elastic rubber sleeve 101, the electric slide rail 102 can be controlled to drive the connecting ring 103 to move upward, so that the elastic rubber sleeve 101 is expanded outward. Fig.11 As shown, at this time, the debris at the elastic rubber sleeve 101 will slide down under the action of gravity and fall along the edges of the elastic rubber sleeve 101 and the soft collection shell 62, making it more convenient to discharge the debris.
