Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adhesive tape cutting, in particular to an adhesive tape cutting device. Background Art
[0002] Adhesive tape is usually supplied in rolls and needs to be cut into a predetermined width when used. In industrial production, the tape is generally cut into the required width by a tape cutting device. Adhesive tape can be widely used in the field of product packaging. However, since the width of the tape purchased on the market usually does not match the product, the tape needs to be cut to the required width during use, so a cutting tool is required.
[0003] For example, a Chinese patent with publication number CN220664425U discloses a tape cutting device, including a base, a winding unwinding mechanism, a pressing mechanism and a cutting mechanism, and a tape guide groove and a first give way groove are provided on the base. The winding unwinding mechanism includes a bracket and a winding unwinding wheel. The pressing mechanism includes a pressing block and a pressing strip, and a second give way groove is provided on the pressing block. The cutting mechanism includes a cutter and a cutter fixing block, and the cutter fixing block includes a cutter limiting groove, and three cutter limiting grooves are provided. The present application provides a tape cutting device, which cuts the tape by a cutter, and limits the cutter by a first give way groove and a second give way groove, so as to ensure that the tape with consistent width and neat incision can be cut, and compared with the cutting method with scissors, the cutting efficiency can be greatly improved. Since three first give way grooves, three second give way grooves and three cutter limiting grooves are provided, tapes of different widths can be cut, thereby improving the applicability of the tape;
[0004] The technical solution recorded in this scheme requires that the tape be put on a pay-off wheel when cutting the tape, but the sizes of the tapes are different and the inner diameters of the winding drums on which they are wound are also different, so the pay-off wheel whose outer diameter cannot be adjusted cannot fix tapes of different sizes, greatly reducing the practicality of the cutting device.
[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a tape cutting device is provided to achieve the purpose of having more practical value. Utility Model Content

[0036] Embodiment 3 of the utility model of a tape cutting device
[0037] Reference Figure 1 - Figure 5 As shown, one end of the second mounting frame 2002 is rotatably connected to a hand wheel 2003, and one end of the hand wheel 2003 is connected to one end of a screw rod 2008 through a coupling. Both ends of the first mounting frame 2001 and the second mounting frame 2002 are provided with a clamping wheel 2007, and the bottom end and side surfaces of the slitting knife 2005 are provided with cutting edges. By connecting the hand wheel 2003 with the screw rod 2008, it is convenient for the user to turn the hand wheel 2003 to rotate the screw rod 2008. By installing the clamping wheel 2007, when the second mounting frame 2002 is pressed down, the clamping wheel 2007 can be used to limit the tape, thereby improving the accuracy of tape cutting. By providing cutting edges at the bottom end and side surfaces of the slitting knife 2005, the slitting knife 2005 can penetrate the tape when it is pressed down, and as one end of the tape moves, its side cutting edge can cut the tape.
[0038] Specifically, the working principle of the tape cutting device is as follows: when in use, the inner ring of the tape roll is sleeved on the outer side of a plurality of abutment plates 1012, and then the turntable 1003 is pressed against to prevent it from rotating, and then the screw rod 1005 is rotated. When the screw rod 1005 rotates, the moving block 1006 threadedly connected thereto moves along with the pair of slide bars 1007, and a plurality of first mounting seats 1008 and second mounting seats 1009 are respectively installed on the outer sides of the moving block 1006 and the connecting column 1004, and the first mounting seat 1008 and the second mounting seat 1009 are hinged with a connecting rod 1010 inside, and the other end of the connecting rod 1010 is hinged to the third mounting seat 1011, and by installing abutment plates 1012 between adjacent third mounting seats 1011, when the moving block 1006 moves, the abutment plates 1012 can be raised as it moves, thereby clamping and fixing the inner ring of the tape roll. After the tape roll is fixed, The user rotates the hand wheel 2003 to drive the screw rod 2008 to rotate, and then the slider 2009 mounted on it drives the slitting knife 2005 to move. After adjusting its position, one end of the tape passes between the first mounting frame 2001 and the second mounting frame 2002, and the telescopic rod 2004 is started to drive the second mounting frame 2002 to press down when it works. Clamping wheels 2007 are installed on both sides of the second mounting frame 2002 and both sides of the first mounting frame 2001. As the second mounting frame 2002 is pressed down, the clamping wheels 2007 squeeze the tape to prevent the tape from deviating when the user pulls the tape. While the second mounting frame 2002 is pressed down, the bottom end of the slitting knife 2005 installed at its bottom end pierces the tape, and its bottom end extends into the inside of the knife groove 2006. As the user pulls the tape, the incision where the tape is pierced is cut by the blade edge opened on one side of the slitting knife 2005, thereby completing the cutting of the tape.
[0039] It should be noted that in a tape cutting device, the specific model and specifications of the telescopic rod 2004 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
[0040] In a tape cutting device, the power supply and principle of the telescopic rod 2004 are clear to those skilled in the art and will not be described in detail here.
[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
