[0032] A method for using a slitting device for processing and producing PE antistatic film, comprising the following steps:

[0033] T1. Before the PE antistatic film roll to be cut needs to be sleeved and fixed to prevent idling, several connecting shells on the cylindrical part are sequentially inserted and matched between the two adjacent fan-shaped long plates, and then the PE antistatic film roll to be cut needs to be sleeved and matched between the several connecting shells.

[0034] T2. After the sleeve connection is completed, the gear bar fixed at the bottom of the first I-shaped slider gradually approaches the thick gear and finally meshes with the thick gear through the sliding connection between the I-shaped block, the plug-in rod, the positioning hole, the toggle rod and the plug-in groove, the plug-in hole, the column and the oblique groove in sequence, so that the gear bar fixed at the bottom of the first I-shaped slider gradually approaches the thick gear and finally meshes with the thick gear, thereby driving the thick gear to rotate.

[0035] When the medium-thick gears T3 and T2 rotate, the sliding cooperation between the sliding columns in the idle parts is respectively carried out through the sliding grooves penetrated through one side of the rotating disk, thereby driving the first slide plate and the second slide plate in the idle parts to slide inside the first rectangular groove and the second rectangular groove respectively, so that the idle parts slide inside the cylindrical part in a trend of mutual expansion until the friction balls in the idle parts fit with the inner wall of the PE antistatic film roll to be cut.

[0036] T4. After the friction balls in several idling parts are in contact with the inner wall of the PE antistatic film roll to be cut, the plug-in sliding fit of the adjusting parts ends. At this time, the thick gear stops rotating, and the PE antistatic film roll to be cut is expanded and fixed, thereby improving the roll changing effect of the PE antistatic film roll to be cut, and further consolidating the roll-wrapping effect of the PE antistatic film roll to be cut on the sleeve assembly after replacement and fixation.

[0037] T5. After the PE antistatic film roll to be cut is replaced and fixed, the starting end of the PE antistatic film roll to be cut passes through the bottom of the tensioning roller and then passes through the top of the conveying roller. After passing through the top of the conveying roller, several cutting pieces are adjusted in fixed positions to perform preliminary cutting on the starting end of the PE antistatic film roll passing through the top of the conveying roller to form starting ends of PE antistatic film rolls of different widths.

[0038] T6. Before slitting the starting end of the PE antistatic film roll, the position of the multiple cutting pieces in the transverse groove is adjusted by pushing the T-shaped slide rail that slides inside the transverse groove and referring to the scale fixed on the top of the transverse plate to determine the spacing between the multiple cutting pieces, so as to form the starting end of the PE antistatic film roll of different widths in the later stage. After the spacing between the multiple cutting pieces is adjusted, the locking bolt is fixedly connected to the top of the transverse plate by rotating the locking bolt.

[0039] After completing steps T7, T1 to T6, start the electric telescopic rod, driving the T-shaped slide fixed to the telescopic end of the electric telescopic rod to move upward between the two columns, thereby driving the entire locking part to move upward on the top of the base, so that the semicircular locking ring that rotates on the annular rail in the locking part and the several locking protrusions fixed to the inner wall of the semicircular locking ring gradually engage with the teeth distributed on the thick gear to ensure that the PE antistatic film roll to be cut that is later sleeved, expanded and fixed on the sleeve assembly is further engaged and fixed.

[0040] T8. After step T2 is completed, the fastening bolt fixed on one side of the fourth bonding plate is rotated to drive the fastening bolt to move threadedly on the movable baffle, thereby driving the translation plate to move horizontally. During the movement, the two T-shaped sliders are driven to slide downward in the two vertical grooves respectively through the sliding cooperation between the oblique groove opened through one side of the translation plate and the toggle rod fixed on one side of a T-shaped slider, thereby driving the tensioning roller fixed between the two T-shaped sliders to slide downward to complete the tension adjustment. During the tension adjustment process, the gear bar meshing with the thick gear gradually moves away from the thick gear, and finally the meshing action between the thick gear and the gear bar disappears.

[0041] After the steps T9, T1 to T8 are completed, the starting ends of the PE antistatic film rolls of different widths are wound around the surface of the winding drum in sequence, and then the winding motor is started to drive the winding motor output shaft to rotate on the fixed winding drum, so that the PE antistatic films of different widths can be rewound after slitting.

[0042] The advantages of the present invention are:

[0043] 1. The present invention enables a plurality of idling parts slidably fitted in the cylindrical part to slide away toward the center position of the cylindrical part through the sliding of the first slide plate and the second slide plate in the idling part in the first rectangular groove and the second rectangular groove respectively, until the friction balls in the plurality of idling parts are in contact with the inner wall of the PE antistatic film roll to be cut, and then the thick gear is stopped to rotate, so as to expand and fix the PE antistatic film roll to be cut which is sleeved and fixed on the sleeve assembly, thereby improving the roll-changing effect of the PE antistatic film roll to be cut, further stabilizing the roll-wrapping effect of the PE antistatic film roll to be cut on the sleeve assembly after it is replaced and fixed, preventing the PE antistatic film roll to be cut from idling on the sleeve assembly after the roll-changing sleeve is fixed, and improving the later slitting effect of the PE antistatic film roll to be cut.

[0044] 2. The present invention drives the locking piece fixed to the telescopic end of the electric telescopic rod to move upward on the top of the base by moving the electric telescopic rod, so that the semicircular locking ring that rotates on the annular rail and the plurality of locking protrusions fixed to the inner wall of the semicircular locking ring gradually engage with the teeth distributed on the thick gear to ensure that the PE anti-static film roll to be cut that is later sleeved and expanded and fixed on the sleeve assembly is further engaged and fixed, so that the PE anti-static film roll to be cut that is sleeved and fixed on the sleeve assembly is finally strengthened, expanded and fixed, and the roll-changing effect of the PE anti-static film roll to be cut is improved, and the roll-covering effect of the PE anti-static film roll to be cut on the sleeve assembly after replacement and fixation is further stabilized, and the PE anti-static film roll to be cut is prevented from idling on the sleeve assembly after the roll-changing sleeve is fixed, thereby improving the later slitting effect of the PE anti-static film roll to be cut.

[0045] 3. The present invention utilizes the sliding plug-in cooperation among the I-shaped block, the plug-in rod, the positioning hole, the toggle rod, the card slot, the plug-in hole, the column, and the oblique slot in sequence, so that the gear bar fixed at the bottom of the first I-shaped slider gradually approaches the thick gear and finally meshes with the thick gear, thereby driving the thick gear to rotate for subsequent expansion, support, positioning, and fixation.

[0046] 4. The present invention drives the two T-shaped sliders to slide downward in the two vertical grooves respectively through the sliding cooperation between the oblique grooves penetrated through one side of the translation plate and the toggle rod fixed on one side of a T-shaped slider, thereby driving the tensioning roller fixed between the two T-shaped sliders to slide downward, and then the upper and lower surfaces of the anti-static film to be cut, which are respectively in contact with the peripheral side surfaces of the tensioning roller and the conveying roller, are tightened and straightened before cutting. During the tightening and straightening operation, the gear bar meshing with the thick gear gradually moves away from the thick gear, and finally the meshing action between the thick gear and the gear bar disappears, thereby avoiding the PE anti-static film roll to be cut from getting stuck when unwinding before cutting, avoiding wrinkles in the later slitting and rewinding process, and preventing the PE anti-static film to be cut from being damaged during the slitting process due to wrinkles during the transmission slitting process, thereby improving the slitting efficiency and quality of the PE anti-static film to be cut.

[0070] The specific application of this second embodiment is:

[0071] After the PE antistatic film roll to be cut is fixed by sleeve anti-idling, the starting end of the PE antistatic film roll to be cut passes through the bottom of the tensioning roller 313, and then passes through the top of the conveying roller 315. After passing through the top of the conveying roller 315, the plurality of cutting pieces 6 are adjusted in a fixed position, so as to perform a preliminary cutting on the starting end of the PE antistatic film roll passing through the top of the conveying roller 315 to form the starting ends of the PE antistatic film rolls of different widths. Before the starting end of the PE antistatic film roll is cut, the adjustment process of the positions of the plurality of cutting pieces 6 in the transverse groove 317 is specifically carried out by pushing the T-shaped slide rail 601 that is slidably fitted in the transverse groove 317, and referring to the scale 31 fixed on the top of the transverse plate 316. 8. Determine the spacing between a plurality of cutting pieces 6 so as to form the starting ends of PE antistatic film rolls of different widths later. After the spacing between the plurality of cutting pieces 6 is adjusted, the locking bolt 602 is rotated so as to be fixedly connected to the top of the transverse plate 316, thereby fixing the plurality of cutting pieces 6 whose positions have been adjusted. After the fixing is completed, the starting ends of the plurality of PE antistatic film rolls of different widths that have been cut are sequentially wound around the peripheral side surface of the winding drum 320 so as to perform the slitting and rewinding operation in the transmission process later. Before the slitting and rewinding operation is performed, the upper and lower surfaces of the antistatic film to be cut are respectively in contact with the peripheral side surfaces of the tensioning roller 313 and the conveying roller 315, and are in a relatively tight state.

[0072] In the process that the upper and lower surfaces of the antistatic film to be cut are respectively attached to the peripheral side surfaces of the tensioning roller 313 and the conveying roller 315, the gear bar 507 fixed at the bottom of the first I-shaped slider 506 gradually approaches the thick gear 805 through the sliding plug-in cooperation among the I-shaped block 501, the plug-in rod 502, the positioning hole 504, the toggle rod 314, the plug-in groove 308, the plug-in hole 309, the column 306, and the oblique groove 519, and finally meshes with the thick gear 805, thereby driving the thick gear 805 to rotate, so as to carry out the subsequent expansion, positioning and fixing, and finally make the entire adjustment member 5 slidably plugged and fixed on the top of the base 301;

[0073] When adjusting the tension during the slitting and rewinding process, the fastening bolt 516 fixed on one side of the fourth bonding plate 515 is rotated to drive the fastening bolt 516 to move on the movable baffle 520. When the fastening bolt 516 moves on the movable baffle 520, the first I-shaped slider 506 and the second I-shaped slider 512 are respectively slidably matched inside the movable groove 505 to perform axial rotation limit, and at the same time, the U-shaped bottom plate 517 fixed at the bottom of the connecting plate 513 and the translation plate 518 fixed on one side of the U-shaped bottom plate 517 are driven to move horizontally. During the movement, the two T-shaped sliders 312 are respectively moved in the two vertical grooves 310 through the sliding cooperation between the oblique groove 519 penetrating through one side of the translation plate 518 and the toggle rod 314 fixed on one side of the T-shaped slider 312. The interior slides downward, thereby driving the tensioning roller 313 fixed between the two T-shaped sliders 312 to slide downward, and then the upper and lower surfaces of the antistatic film to be slit, which are respectively in contact with the peripheral side surfaces of the tensioning roller 313 and the conveying roller 315, are stretched and straightened before slitting. During the stretching and straightening operation, the gear bar 507 meshing with the thick gear 805 gradually moves away from the thick gear 805, and finally the meshing action between the thick gear 805 and the gear bar 507 disappears, thereby preventing the PE antistatic film roll to be slit from getting stuck when unwinding before slitting, preventing it from wrinkling during the subsequent slitting and rewinding process, and preventing the PE antistatic film to be slit from being damaged during the slitting process due to wrinkles during the transmission slitting process, thereby improving the slitting efficiency and quality of the PE antistatic film to be slit.

[0074] Embodiment 3, a method for using a slitting device for processing and producing PE antistatic film, comprising the following steps:

[0075] T1. Before the PE antistatic film roll to be cut needs to be sleeved and fixed to prevent idling, the several connecting shells 701 on the cylindrical member 7 are sequentially inserted and matched between the two adjacent sector-shaped long plates 305, and then the PE antistatic film roll to be cut needs to be sleeved and matched between the several connecting shells 701;

[0076] T2. After the sleeve connection is completed, the gear bar 507 fixed at the bottom of the first I-shaped slider 506 gradually approaches the thick gear 805 through the sliding connection between the I-shaped block 501, the plug rod 502, the positioning hole 504, the toggle rod 314, the plug-in groove 308, the plug hole 309, the column 306, and the oblique groove 519, and finally meshes with the thick gear 805, thereby driving the thick gear 805 to rotate;

[0077] When the T3 and T2 medium-thick gears 805 rotate, the plurality of arc grooves 803 penetrating through one side of the rotating disk 802 respectively slide with the sliding posts 905 in the plurality of idle parts 9, thereby driving the first slide plate 901 and the second slide plate 904 in the idle parts 9 to slide in the first rectangular groove 702 and the second rectangular groove 703, respectively, so that the plurality of idle parts 9 slide in a mutually expanding trend in the cylinder part 7 until the friction balls 903 in the plurality of idle parts 9 fit with the inner wall of the PE antistatic film roll to be cut;

[0078] T4. After the friction balls 903 in the idle parts 9 are in contact with the inner wall of the PE antistatic film roll to be cut, the plug-in sliding fit of the adjusting part 5 ends. At this time, the thick gear 805 stops rotating, and the PE antistatic film roll to be cut is expanded and fixed, thereby improving the roll-changing effect of the PE antistatic film roll to be cut, and further stabilizing the roll-wrapping effect of the PE antistatic film roll to be cut on the sleeve assembly 2 after replacement and fixing;

[0079] T5. After the PE antistatic film roll to be cut is replaced and fixed, the starting end of the PE antistatic film roll to be cut passes from the bottom of the tensioning roller 313, and then passes through the top of the conveying roller 315. After passing through the top of the conveying roller 315, the plurality of cutting pieces 6 are adjusted in fixed positions, so as to perform preliminary cutting on the starting end of the PE antistatic film roll passing through the top of the conveying roller 315, so as to form the starting ends of the PE antistatic film rolls of different widths;

[0080] T6. Before the starting end of the PE antistatic film roll is cut, the position of the multiple cutting pieces 6 in the transverse groove 317 is adjusted by pushing the T-shaped slide rail 601 that is slidably fitted in the transverse groove 317, and referring to the scale 318 fixed on the top of the transverse plate 316, to determine the spacing between the multiple cutting pieces 6, so as to form the starting ends of the PE antistatic film rolls of different widths later. After the spacing between the multiple cutting pieces 6 is adjusted, the locking bolt 602 is rotated so that the locking bolt 602 is fixedly connected to the top of the transverse plate 316;

[0081] After the steps T7, T1 to T6 are completed, the electric telescopic rod 307 is started, driving the T-shaped slide plate 401 fixed to the telescopic end of the electric telescopic rod 307 to move upward between the two columns 306, thereby driving the entire locking member 4 to move upward on the top of the base 301, so that the semicircular locking ring 406 rotating on the annular rail 405 in the locking member 4 and the plurality of locking protrusions 407 fixed on the inner wall of the semicircular locking ring 406 gradually engage with the teeth distributed on the thick gear 805 to ensure that the PE antistatic film roll to be cut that is later sleeved, expanded and fixed on the sleeve assembly 2 is further engaged and fixed;

[0082] T8. After step T2 is completed, by rotating the fastening bolt 516 fixed on one side of the fourth laminating plate 515, the fastening bolt 516 is driven to move on the movable baffle 520, and the translation plate 518 is driven to move in the horizontal direction. During the movement, the two T-shaped sliders 312 are driven to slide downward in the two vertical grooves 310 respectively through the sliding cooperation between the oblique groove 519 penetrating through one side of the translation plate 518 and the toggle rod 314 fixed on one side of a T-shaped slider 312, thereby driving the tensioning roller 313 fixed between the two T-shaped sliders 312 to slide downward, and the tension adjustment is completed. During the tension adjustment process, the gear bar 507 meshing with the thick gear 805 gradually moves away from the thick gear 805, and finally the meshing action between the thick gear 805 and the gear bar 507 disappears;

[0083] After completing steps T9, T1 to T8, the starting ends of the PE antistatic film rolls of different widths are sequentially wound around the surface of the winding drum 320, and then the winding motor 319 is started to drive the winding drum 320 fixed on the output shaft of the winding motor 319 to rotate, so that the PE antistatic films of different widths can be rewound after slitting.

During the movement, the two T-shaped sliders (312) are driven to slide downward in the two vertical grooves (310) respectively through the sliding cooperation between the oblique groove (519) opened through one side of the translation plate (518) and the toggle rod (314) fixed on one side of the T-shaped slider (312), thereby driving the tensioning roller (313) fixed between the two T-shaped sliders (312) to slide downward, and the tension adjustment is completed. During the tension adjustment process, the gear bar (507) meshing with the thick gear (805) gradually moves away from the thick gear (805), and finally the meshing action between the thick gear (805) and the gear bar (507) disappears; After steps T9 and T1 to T8 are completed, the starting ends of the PE antistatic film rolls of different widths are sequentially wound around the surface of the winding drum (320), and then the winding motor (319) is started to drive the winding drum (320) fixedly sleeved on the output shaft of the winding motor (319) to rotate, so that the PE antistatic films of different widths can be rewound after being slit.
