[0035] A ribbon slitting device, characterized by comprising: a bracket 100, a reeling roller 200, a cutting roller 400, and a reeling roller 600;

[0036] A unwinding roller 200 is rotatably provided in the middle of the bracket 100, and the required stripped ribbon is wound on the unwinding roller 200, and the cutting roller 400 is rotatably provided behind the unwinding roller 200, so that the ribbon unwound from the unwinding roller 200 can be cut by the cutting roller 400, and the winding roller 600 is rotatably provided behind the cutting roller 400, and a tape 640 is wound on the winding roller 600, one end of the tape 640 is fixed to the surface of the winding roller 600, and the other end of the tape 640 is provided with a joint 641, and the joint 641 can be fixed to the end of the ribbon, so that when the winding roller 600 rotates, the ribbon cut by the cutting roller 400 can be guided by the tape 640 to the winding roller 600 to complete the winding.

[0037] When using the utility model, first rotate the winding roller to untie the tape, pull the joint to connect it with the end of the tape, and then rotate the unwinding roller, the winding roller and the cutting roller synchronously, and the tape is guided to the cutting roller for cutting. The cut and stripped tape continues to move toward the winding roller under the guidance of the joint, and when it reaches the winding roller, it is wound on the winding roller to complete the winding.

[0038] As a preferred embodiment of the present invention, a rotatable pressure roller 300 is further provided in the middle of the bracket 100. The pressure roller 300 is provided behind the unwinding roller 200 and in front of the cutting roller 400. The pressure roller 300 is provided on the same horizontal plane as the cutting roller 400, so that the webbing can first pass through the pressure roller 300 and then be cut by the cutting roller 400. The pressure roller is provided between the unwinding roller and the cutting roller, so that the webbing passes through the pressure roller before being guided to the cutting roller. The webbing passing through the pressure roller can rub against the pressure roller to reduce impurities adhering to the surface, thereby preventing impurities from sticking to the cutting blade during subsequent cutting and causing contamination and affecting its use. At the same time, after passing through the pressure roller, the webbing is on the same horizontal plane as the cutting roller, which can facilitate the webbing to pass through the cutting roller without difficulty due to excessive angles.

[0039] As a preferred embodiment of the present invention, a rotatable limiting roller 500 is further provided in the middle of the bracket 100. The limiting roller 500 is provided behind the cutter roller 400 and in front of the reeling roller 600. The limiting roller 500 is provided at the same horizontal plane as the cutter roller 400, so that the cut ribbon can first pass through the limiting roller 500 and then be reeled by the reeling roller 600. The limiting roller is provided behind the cutter roller. Similarly, at this time, the other side of the ribbon can be slid over the limiting roller to rub and clean impurities adhering to the other side of the ribbon, ensuring that the surface of the subsequently reeled ribbon is clean. At the same time, the ribbon passing through the cutter roller can continue to be maintained at the same horizontal plane, preventing the ribbon from being torn at the cutting point due to excessive upward angle of the ribbon when the reeling device is set relatively high, and ensuring that the ribbon strips are only cut by the cutter.

[0040] As a preferred embodiment of the present invention, the cutter roller 400 is provided with multiple cutters, and the winding roller 600 is composed of multiple small rollers 650 connected together. The spacing between the cutters is the same as the length of the corresponding small rollers 650. The multiple cutters and multiple small rollers can form a variety of widths of ribbon strips and winding.

[0041] As a preferred embodiment of the present invention, the unwinding roller 200 includes a clamping shaft 210 and a support shaft 220, the pressing roller 300 also includes a clamping shaft 310 and a support shaft 2 320, the cutting roller 400 also includes a clamping shaft 410 and a support shaft 3 420, the winding roller 600 also includes a clamping shaft 410 and a support shaft 4 620, the bracket 100 also includes a chuck 110 and a support groove 120 arranged on the inner side wall, and there are four chucks 110 and four support grooves 120, and the clamping shaft 1 210, the clamping shaft 2 310, the clamping shaft 3 410, and the clamping shaft 4 610 can all be engaged with the chuck 110, and the support shaft 1 220, the support shaft 2 320, the support shaft 3 420, and the support shaft 4 620 can all be placed on the support groove 120. The chuck is configured with multiple sector-shaped surfaces connected to each other, with the sector-shaped surfaces alternating in height. A sleeve is provided on the outer periphery of the chuck, and the end of the card shaft is also configured with sector-shaped surfaces connected to each other alternating in height, so that the card shaft can be inserted into the sleeve and engaged with the chuck. The support shaft is placed in the support groove and can rotate, so that the card shaft can be driven to rotate when the chuck rotates. At the same time, this configuration also makes each roller detachable, which is convenient for replacement when it fails.

[0042] As a preferred embodiment of the present invention, the three chucks 110 corresponding to the first chuck shaft 210, the second chuck shaft 310, and the third chuck shaft 410 are connected by a belt 140. A motor 130 is provided inside the bracket 100. The motor 130 is provided on one of the chucks 110, so that when the motor 130 drives one of the chucks 110 to rotate, the belt 140 can also drive the remaining two chucks 110 to rotate. Connecting the chucks by belts and using motors to drive their rotation can save the number of motors used, ensure that the unwinding roller, the pressure roller, and the cutter roller can rotate synchronously, and prevent asynchronous rotation from causing unsmooth webbing conveying.

[0043] As a preferred solution of the present invention, the joint portion 641 is a hook or a tape, so that the hook can hook the end of the ribbon or the tape can stick to the end of the tape.

[0044] As a preferred embodiment of the present invention, the small rollers 650 are separated by a stop plate 630, and the size of the stop plate 630 matches the size of the small rollers 650. The stop plate is provided between the small rollers to prevent the wound ribbon from deviating and falling off, thereby ensuring the stability of the winding.

[0045] In summary, the utility model provides a webbing stripping device, which realizes that when the webbing is unwound from the unwinding roller, it is cut and stripped at the cutter roller, and then the stripped webbing is wound on the winding roller. One end of the webbing is fixed to the winding roller, and the other end is set as a joint. The joint can be set as a hook or tape. The joint is connected with the end of the webbing, and the webbing can be guided to the winding roller for winding when the winding roller is rotated. This arrangement avoids the tediousness of manually guiding the end of the webbing to the cutter and also avoids the risk of injury. The rollers are detachable, which can be easily replaced. The arrangement of multiple cutters and small rollers can also effectively cut and rewind webbings of different widths. The arrangement of the pressure roller and the limit roller can also clean impurities by friction. The arrangement of the gear plate can also prevent the wound webbing from falling off.
