DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 6 As shown, a flexible static electricity removal device for a biaxially oriented polypropylene film winding mechanism comprises a workbench 1, a winding roller 3, a mounting seat 4 and an static electricity brush 6; two mounting boxes 2 are symmetrically arranged on the workbench 1, and a revolving door 21 is arranged on the mounting box 2; the winding roller 3 is arranged on the mounting box 2 through a bearing seat 411; the mounting seat 4 is arranged on a side of the mounting box 2 away from the winding roller 3, and a connecting frame 5 is arranged on the mounting seat 4; the static electricity brush 6 is movably arranged on the connecting frame 5, the static electricity brush 6 can be arranged in contact with the winding roller 3, and a connecting mechanism 7 connected to the static electricity brush 6 is arranged on the connecting frame 5.

[0024] When the device is used to stretch the polypropylene film, the starting end of the polypropylene film is first placed on the winding roller 3, and then the winding roller 3 is driven to rotate to stretch the polypropylene film. Then, during the stretching process of the polypropylene film, the polypropylene film can be destaticized by the operation of the electrostatic brush 6. The electrostatic removal method of the polypropylene film by the electrostatic brush 6 is a flexible electrostatic removal method, which can better protect the polypropylene film. When the electrostatic brush 6 is damaged or has been working for a long time, the electrostatic brush 6 can be quickly removed from the connecting frame 5 and replaced. Through the setting of the connecting mechanism 7, the electrostatic brush 6 can be quickly removed from the connecting frame 5 or installed on the connecting frame 5, thereby improving the convenience of replacing and installing the electrostatic brush 6, and thus reducing the impact on the electrostatic removal of the polypropylene film.

[0025] Reference Figure 2 and Figure 3 As shown, the connecting mechanism 7 includes a slider 71 and a connecting block 73; the slider 71 is movably arranged on the connecting frame 5, and the connecting frame 5 is provided with a slide groove 72 for the slider 71 to move; the connecting block 73 is arranged at the bottom of the slider 71, and the connecting block 73 is connected to the electrostatic brush 6.

[0026] When the electrostatic brush 6 needs to be replaced, the electrostatic brush 6 is directly held and pulled at the same time, so that the slider 71 slides out of the slide groove 72 of the connecting frame 5. Since the electrostatic brush 6 and the connecting block 73 are detachably connected, the electrostatic brush 6 can be quickly replaced. After the electrostatic brush 6 is replaced, the slider 71 can be directly inserted into the slide groove 72 of the connecting frame 5, thereby improving the convenience of replacing the electrostatic brush 6.

[0027] Reference Figure 4 As shown, a fixing assembly 74 is provided on the connecting frame 5, and the fixing assembly 74 includes a contact column 741. The contact column 741 is provided on the connecting frame 5, and one end of the contact column 741 close to the connecting frame 5 can penetrate the connecting frame 5 and contact the slider 71, and the slider 71 is provided with a contact hole 742 for the contact column 741 to contact.

[0028] After the electrostatic brush 6 is installed on the connecting frame 5, the abutment column 741 is inserted into the connecting frame 5 and the abutment column 741 is inserted into the abutment hole 742 of the slider 71. In this way, the slider 71 is fixed on the connecting frame 5, and the electrostatic brush 6 is further fixed. This can prevent the electrostatic brush 6 from being offset during operation, thereby affecting the effect of removing static electricity from the polypropylene film.

[0029] Reference Figure 4 As shown, a reset portion 75 is provided on the connecting frame 5, and the reset portion 75 includes a limit frame 751, a limit ring 752 and a spring 753; the limit frame 751 is arranged on the side of the connecting frame 5 close to the abutment column 741, and the limit frame 751 is provided with a through hole for the abutment column 741 to pass through; the limit ring 752 is arranged on the abutment column 741, and the limit ring 752 can be abutted against the connecting frame 5; the spring 753 is sleeved on the abutment column 741, and one end of the spring 753 is abutted against the limit ring 752, and the other end is abutted against the limit frame 751.

[0030] When it is necessary to remove or install the electrostatic brush 6, it is necessary to first pull the abutment column 741 so that the abutment column 741 moves toward the side away from the connecting frame 5. In this way, the abutment column 741 will synchronously drive the limiting ring 752 to move during the movement, and the limiting ring 752 will squeeze the spring 753, so that the spring 753 is compressed and has an elastic restoring force. In this way, when the slider 71 is completely inserted into the slide groove 72 of the connecting frame 5, the abutment column 741 is directly released. In this way, the abutment column 741 will be reset by the work of the spring 753, so that the abutment column 741 is automatically inserted into the abutment hole 742 of the slider 71. This can make it more convenient to operate the abutment column 741, and can also prevent the abutment column 741 from detaching from the connecting frame 5.

[0031] Reference Figure 2 and Figure 6 As shown, a dust suction mechanism 8 is provided on the connecting frame 5, and the dust suction mechanism 8 includes a dust suction box 81 and an air suction hood 82; the dust suction box 81 is provided on the connecting frame 5, and an air suction port 811 and a connecting port 812 are respectively provided on the dust suction box 81; the air suction hood 82 is provided at the connecting port 812 of the dust suction box 81, and the working end of the air suction hood 82 faces the electrostatic brush 6.

[0032] Through the setting of the dust box 81, the working end of the external vacuum cleaner is connected to the suction port 811 on the dust box 81, so that after the electrostatic brush 6 has worked for a period of time, the external vacuum cleaner is started, and the dust on the electrostatic brush 6 can be adsorbed through the connection port 812 on the dust box 81. Through the setting of the suction hood 82, the dust on the electrostatic brush 6 can be better adsorbed, and when the electrostatic brush 6 electrostatically treats the polypropylene film, some dust may still fly outward. In this way, the dust flying outward can be better adsorbed through the suction hood 82, thereby improving the cleanliness of the surface of the polypropylene film.

[0033] Reference Figure 5 As shown, a moving component 22 is provided on the installation box 2, and the moving component 22 includes a telescopic cylinder 221 and a fixed block 222; the telescopic cylinder 221 is provided on the installation box 2, and the working end of the telescopic cylinder 221 can penetrate the outer wall surface of the installation box 2 and extend inward; the fixed block 222 is provided on the working end of the telescopic cylinder 221, and the fixed block 222 is connected to the mounting seat 4.

[0034] By starting the telescopic cylinder 221, when the working end of the telescopic cylinder 221 is extended or retracted, the mounting seat 4 is synchronously driven to move through the setting of the fixed block 222, and then the electrostatic brush 6 is driven to move, so that the thickness of the polypropylene film will not gradually increase during the process of stretching and winding the polypropylene film by the winding roller 3, thereby reducing the distance between the electrostatic brush 6 and the polypropylene film. In this way, the electrostatic brush 6 will be driven by the telescopic cylinder 221 to gradually move away from the polypropylene film, thereby reducing the influence of the electrostatic brush 6 during the electrostatic treatment of the polypropylene film.

[0035] Reference Figure 5 and Figure 6 As shown, a flattening assembly 41 is arranged on the mounting seat 4, and the flattening assembly 41 includes a bearing seat 411 and a pressure roller 413; the bearing seat 411 is arranged on the mounting seat 4, and an arc groove 412 for the bearing seat 411 to move is arranged on the mounting box 2; the pressure roller 413 is rotatably arranged on the bearing seat 411.

[0036] By setting the pressing roller 413, during the process of stretching and winding the polypropylene film by the winding roller 3, the pressing roller 413 will also abut against and rotate with the polypropylene film. In this way, the setting of the pressing roller 413 can flatten the entire polypropylene film, and can also prevent the edge of the polypropylene film from warping, thereby affecting the quality of the polypropylene film. The bearing seat 411 moves in the arc groove 412 of the mounting seat 4, so that when the mounting seat 4 moves, it drives the pressing roller 413 to move together, so that the pressing roller 413 can always be in better contact with the polypropylene film.

[0037] Reference Figure 6 As shown, the installation box 2 is also provided with a guide portion 23, and the guide portion 23 includes a guide block 231. The guide block 231 is movably arranged on the installation box 2, and a guide groove 232 for the guide block 231 to move is arranged on the installation box 2, and the guide block 231 is connected to the connecting frame 5.

[0038] By moving the guide block 231 in the guide groove 232 of the installation box 2, the connecting frame 5 can be limited again, thereby preventing the connecting frame 5 from being affected by the large number of components and heavy weight on the connecting frame 5, thereby making the connecting frame 5 more stable during operation and extending its service life.

[0039] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
