[0016] A method for a cutting device for processing a degradable heat-sealing tape comprises the following steps:

[0017] Step 1: Place the degradable heat-sealing tape to be cut on the turntable, pass the tape through the gap between the auxiliary roller and the electric feeding roller, and enter the cutting area between the movable knife disc and the fixed knife head under the guidance of the guide roller, and then clamp the starting end of the tape on the electric clamp;

[0018] Step 2: Activate the DD motor to drive the worm gear to rotate clockwise. The meshing transmission between the worm plate and the worm gear drives the block plate to move down along the guide rod under the guidance of the guide cavity, clamping the tape between the elliptical strip on the auxiliary roller and the elliptical strip on the electric feeding roller; then activate the electric feeding roller to rotate counterclockwise at the same time, activate the electric slide module to drive the electric clamp to move to the left, so that the tape reaches the preset cutting length;

[0019] Step 3: After the tape reaches the preset cutting length, the electric cylinder is activated while the cutting motor is activated to drive the movable knife disc to rotate. The electric cylinder drives the movable knife disc to move toward the middle of the inner side of the U-shaped tube. When the knife disc approaches the tape, the two fixed knife heads cooperate to cut the tape from the middle to both sides, thereby completing the cutting operation of the tape.

[0020] The present invention provides a cutting device and method for processing a degradable heat-sealing tape, which has the following beneficial effects:

[0021] 1. The cutting device and method for processing degradable heat-sealing tape can bend the grinding sheet and fit it on the blade of the movable knife disc by simultaneously activating the two first telescopic rods for extension. At this time, the movable knife disc is driven to rotate by activating the cutting motor, and the grinding sheet can be used to scrape off stubborn residues. The blade of the movable knife disc can also be automatically polished, so that the blade of the movable knife disc is always kept sharp, effectively ensuring the cutting accuracy, sharpness, stability and effect of the movable knife disc on the tape.

[0022] 2. The cutting device and method for processing degradable heat-sealing tape, by activating an air pump machine, uses an inclined nozzle opened at the end of a flat tube to horizontally correspond to the scraper shell to spray and blow the residue on the blade of the movable knife disc into the scraper shell, thereby realizing a contactless cleaning function for the residue on the blade of the movable knife disc. Not only can the residue on the blade of the movable knife disc be cleaned in real time, but also the cutting accuracy, edge neatness and cutting effect of the movable knife disc can be ensured, thereby extending the service life of the movable knife disc and reducing the replacement frequency and maintenance cost.

[0023] 3. The cutting device and method for processing degradable heat-sealing tape, through the design of the U-shaped tube, can not only serve as a receiving container for residues that fall off from the fixed cutter head, but also can use the flat cavity opened in the middle of the U-shaped tube to allow the movable knife disc to vertically descend to the inside of the U-shaped tube, and cope with the cutting operation of tapes of different widths, and perform cutting actions of different descending depths.

[0024] 4. The cutting device and method for processing degradable heat-sealing tape utilizes the convenient insertion of the plug in the socket so that the fixed cutter head can be flexibly removed from the second bracket, so that the residue on the fixed cutter head after long-term use can be simply wiped and cleaned to prevent the residue from affecting the cutting accuracy of the tape by the fixed cutter head in cooperation with the movable cutter disc.

[0025] 5. The cutting device and method for processing degradable heat-sealing tape, through the U-shaped tube being installed in a left-right symmetrical shape and matched on the necessary path of the movable knife disc when it descends for cutting, can effectively provide longitudinal support on both sides of the part where the tape is cut, so that the movable knife disc can quickly cut the tape without causing a decrease in accuracy due to uneven local force on the tape. In addition, the cutting method from the middle to both sides can maintain the stability of the tape well during the entire cutting process, ensuring that the tape will not be laterally or longitudinally deflected or twisted due to the contact of the cutting action, thereby ensuring the cutting accuracy of the tape and effectively reducing the cutting error.

[0026] 6. The cutting device and method for processing degradable heat-sealing tape guides the tape between the electric clamp and the electric feed roller by means of a guide roller in cooperation with an auxiliary roller and an electric feed roller. The guide roller can rotate counterclockwise through the reverse gear sleeve and elastic teeth in cooperation with the anti-reverse gear, while the guide roller is locked clockwise with the anti-reverse gear through the reverse gear sleeve and elastic teeth. This structure design enables the guide roller to guide the tape from right to left in one-way transmission. This ensures that while the tape is clamped by the electric clamp and moved horizontally to the left for tensioning, the tape is in a tensioned and taut state in the area to be cut, and the tape will not flow back to the right due to uneven force during cutting. This ensures the accuracy of the tape when it is cut, and also provides an auxiliary anti-backflow effect for the one-way conveying of the tape.

[0027] 7. The cutting device and method for processing degradable heat-sealing tape, by using an elliptical strip as the contact structure between the auxiliary roller and the electric feed roller and the tape, can effectively reduce the risk of the tape sticking to the auxiliary roller or the electric feed roller, so that the auxiliary roller and the electric feed roller can jointly transport the tape safely and smoothly, and by utilizing the structural design protruding from the auxiliary roller and the electric feed roller, when the tape accidentally breaks or the electric clamp is not clamped and accidentally entangled or stacked, the elliptical strip can be used to lift the tape from the surface of the auxiliary roller or the electric feed roller, thereby preventing the tape from sticking to the auxiliary roller or the electric feed roller over a large area and affecting the calibration and normal use of the tape, ensuring that the tape can be quickly torn off the auxiliary roller or the electric feed roller by manual operation, and returning to the normal cutting operation process, providing a certain guarantee mechanism for the smooth operation of the tape.

[0028] 8. The cutting device and method for processing degradable heat-sealing tape, the design of the U-shaped tube can not only serve as a receiving container for residues that fall off from the fixed cutter head, but also can use the flat cavity opened in the middle of the U-shaped tube to allow the movable knife disc to vertically descend to the inside of the U-shaped tube, and cope with the cutting operation of tapes of different widths, and perform cutting actions of different descending depths.

[0060] Finally, when the tape reaches the preset cutting length, the electric cylinder 8 is activated and the cutting motor 15 is activated at the same time to drive the movable knife disc 7 to rotate, while the electric cylinder 8 drives the movable knife disc 7 to move toward the middle of the inner side of the U-shaped tube 62. While the movable knife disc 7 is close to the tape, the tape is cut from the middle to both sides under the cooperation of the two fixed knife heads 6, thereby completing the cutting operation of the tape; then, the electric slide module 92 can be continuously activated, and the square slide 93 drives the electric clamp 94 to grab the tape and move horizontally to the right, and the cut tape can be temporarily placed in the middle of the guide table 9, and then the tape taking mechanism installed at the top window of the support frame 1 can be used to take out the tape in time; at this time, by repeating the above operation, the tape is continued to be conveyed by the electric feeding roller 4 to cut the next section of the tape.

[0061] During use, the second telescopic rod 33 can be retracted to release the support and shielding of the end of the long shaft rod 32 by the support block 34, exposing the end of the long shaft rod 32 close to the second telescopic rod 33, thereby facilitating the quick removal of the turntable 3 from the second telescopic rod 33 and facilitating the quick installation of a new degradable heat-sealing tape to be cut. Through this convenient disassembly and assembly structural design, the replacement process of the degradable heat-sealing tape on the turntable 3 is smooth and convenient, which can save a lot of time wasted on the preparation work before cutting, and help improve the cutting efficiency of the cutting equipment for the degradable heat-sealing tape.

[0062] At the same time, the support block 34 is used to provide horizontal support for the end of the long axis rod 32 close to the support block 34, which can effectively ensure that the end of the long axis rod 32 close to the support block 34 and the end away from the support block 34 are on the same axis, so that the long axis rod 32 as a whole can provide stable support for the turntable 3, and can balance the gravity of the degradable heat-sealing tape carried by the long axis rod 32, prevent the long axis rod 32 from being partially bent and deformed, and ensure that the turntable 3 can rotate normally on the long axis rod 32.

[0063] When the electric feed roller 4 and the auxiliary roller 44 are used to guide the conveying of the tape, the DD motor 46 can be enabled to drive the worm gear 47 to twist counterclockwise or clockwise on the inside of the plate 42, and the meshing transmission between the worm plate 431 and the worm gear 47 can be used to drive the block plate 43 to be raised and lowered along the guide cavity 421 on the right side of the plate 42 under the vertical guidance of the guide rod 48, so that the distance between the auxiliary roller 44 and the electric feed roller 4 can be accurately changed, and the distance between the two elliptical strips 45 on the auxiliary roller 44 and the electric feed roller 4 can be accurately changed, so that degradable heat-sealing tapes of different thicknesses can be conveyed.

[0064] The guide roller 5 cooperates with the auxiliary roller 44 and the electric feed roller 4 to guide the tape between the electric clamp 94 and the electric feed roller 4. The guide roller 5 can rotate counterclockwise through the reverse gear sleeve 55 and the elastic teeth 531 in cooperation with the anti-reverse gear 53, while the guide roller 5 cooperates with the anti-reverse gear 53 through the reverse gear sleeve 55 and the elastic teeth 531 to lock clockwise with the anti-reverse gear 53, so as to realize the one-way transmission and guidance of the tape from right to left by the guide roller 5. This can ensure that when the tape is clamped by the electric clamp 94 and moved horizontally to the left for tensioning, the tape is in a tensioned and taut state in the area to be cut, and the tape will not flow back to the right due to uneven force during cutting, thereby ensuring the accuracy of the tape when being cut, and also providing an auxiliary anti-reverse effect on the one-way conveying of the tape.

[0065] The U-shaped tube 62 is installed in a left-right symmetrical manner and matched with the necessary path of the movable knife disc 7 when it descends to cut, so as to effectively provide longitudinal support to both sides of the part where the tape is cut, so that the movable knife disc 7 can quickly cut the tape without causing a decrease in accuracy due to uneven local force on the tape. In addition, this cutting method from the middle to both sides can maintain the stability of the tape well during the entire cutting process, ensuring that the tape will not be laterally or longitudinally deflected or twisted due to the contact of the cutting action, thereby ensuring the cutting accuracy of the tape and effectively reducing the cutting error.

[0066] At the same time, by conveniently inserting the plug block 63 into the socket 611, the fixed cutter head 6 can be flexibly removed from the second bracket 61, so that the residue on the fixed cutter head 6 after long-term use can be simply wiped and cleaned to prevent the residue from affecting the cutting accuracy of the fixed cutter head 6 and the movable cutter disc 7 on the tape.

[0067] Through the design of the U-shaped tube 62, it can not only serve as a container for residues that fall off the fixed blade head 6, but also can make use of the flat cavity 621 opened in the middle of the U-shaped tube 62 to allow the movable blade disc 7 to vertically descend to the inside of the U-shaped tube 62, so as to cope with the cutting operation of tapes of different widths and perform cutting actions of different descending depths.

[0068] During the cutting of the tape, the air pump machine 10 can be activated, and the inclined nozzle 161 opened at the end of the flat tube 16 can be horizontally corresponding to the scraper shell 13 to spray and blow the residue on the blade of the movable knife disc 7 into the scraper shell 13, thereby realizing the contactless cleaning function of the residue on the blade of the movable knife disc 7. Not only can the residue on the blade of the movable knife disc 7 be cleaned in real time, but also the cutting accuracy, edge neatness and cutting effect of the movable knife disc 7 can be ensured, thereby extending the service life of the movable knife disc 7 and reducing the replacement frequency and maintenance cost.

[0069] The second embodiment is based on the first embodiment. Figure 6As shown, a ridge 451 is fixedly connected to the surface of the elliptical bar 45, and the surfaces of the auxiliary roller 44 and the electric feeding roller 4 are provided with grooves 441 in a circular array. The elliptical bar 45 is mounted in an interlocking manner with the electric feeding roller 4 through the cooperation of the ridge 451 and the groove 441. Similarly, the elliptical bar 45 is mounted in an interlocking manner with the auxiliary roller 44 through the cooperation of the ridge 451 and the groove 441.

[0070] When in use, the elliptical strip 45 is used as the contact structure between the auxiliary roller 44 and the electric feed roller 4 and the tape, which can effectively reduce the risk of the tape sticking to the auxiliary roller 44 or the electric feed roller 4, so that the auxiliary roller 44 and the electric feed roller 4 can jointly transport the tape safely and smoothly, and by utilizing this structural design protruding from the auxiliary roller 44 and the electric feed roller 4, when the tape accidentally breaks or the electric clamp 94 is not clamped and accidentally entangled or stacked, the elliptical strip 45 can be used to lift the tape from the surface of the auxiliary roller 44 or the electric feed roller 4 to prevent the tape from sticking to the auxiliary roller 44 or the electric feed roller 4 over a large area, thereby affecting the calibration and normal use of the tape, and ensuring that the tape can be quickly torn off the auxiliary roller 44 or the electric feed roller 4 by manual operation, and returning to the normal cutting operation process, providing a certain guarantee mechanism for the smooth operation of the tape.

[0071] Before use, the elliptical strip 45 on the auxiliary roller 44 and the electric feeding roller 4 can be removed, specifically the convex ridge 451 can be pulled out from the slot 441, thereby converting the surface of the elliptical strip 45 and the electric feeding roller 4 into an incomplete curved surface structure, thereby shortening the torque of the auxiliary roller 44 and the electric feeding roller 4 on the tape, and enhancing the conveying force of the auxiliary roller 44 and the electric feeding roller 4 tank body on the tape, so as to be better suitable for the smooth conveying of thicker tape or harder tape. At the same time, the opened slot 441 is also used as a convenient structural design to prevent the tape from sticking to the auxiliary roller 44 or the electric feeding roller 4 and to facilitate quick tearing off. The auxiliary roller 44 and the electric feeding roller 4 in such a use state still have a safe operation mechanism to ensure the smooth operation of the tape and a quick recovery mechanism to prevent sticking.

[0072] The third embodiment is based on the first and second embodiments. Fig.13 and Fig.14As shown, the scraper shell 13 is installed corresponding to the oblique nozzle 161 opened on the flat tube 16 through the small bracket 11 and the frame 12, so that the flat tube 16 can blow the residue into the scraper shell 13 and finally collect it in the glue storage box 14. The scraper shell 13 is provided with a notch in the middle of one side away from the glue storage box 14, and the movable blade disc 7 fits with the notch, so that the movable blade disc 7 can pass through the middle of the scraper shell 13 through the notch without affecting the normal rotation of the movable blade disc 7. At the same time, the scraper shell 13 is guaranteed to collect the residues blown off the blade. Grinding sheets 131 are connected to both sides of the notch on the scraper shell 13. A first telescopic rod 132 is installed between the grinding sheet 131 and the scraper shell 13. The telescopic end of the first telescopic rod 132 is connected to the grinding sheet 131. The grinding sheet 131 is in contact with the blade of the movable cutter disc 7 through the extension of the first telescopic rod 132, so as to grind the blade of the movable cutter disc 7.

[0073] When in use, by simultaneously activating the two first telescopic rods 132 for extension, the grinding sheet 131 can be bent and fit onto the blade of the movable knife disc 7. At this time, by activating the cutting motor 15 to drive the movable knife disc 7 to rotate, the grinding sheet 131 can be used to scrape off stubborn residues, and the blade of the movable knife disc 7 can also be automatically polished, so that the blade of the movable knife disc 7 is always kept sharp, effectively ensuring the cutting accuracy, sharpness, stability and effect of the movable knife disc 7 on the tape.
