Description

Technical Field

[0001] This utility model relates to the field of line marking auxiliary construction technology, and in particular to a tape cutting tool and a tape marking machine using the tool. Background Art

[0002] Before roads, factories, and workshops are officially put into use, different types of adhesive tape need to be laid on the ground to serve as indicators, reminders, or warnings, depending on the specific needs. To reduce the labor intensity of the laying personnel, professional line marking machines are currently mainly used for marking. However, most common line marking machines do not have a cutting function. After the indicator lines are drawn, operators still need to bend over and manually cut the tape, increasing their workload. In addition, the cut edges of the tape may have rough edges, affecting the appearance.

[0003] Patent publication number "CN215561804U" discloses "a vertical marking machine," comprising: a compaction roller connected to a main support; a vertical support connected to the main support; the vertical support having a hand handle, a tape holder, and a limiting baffle installed sequentially from top to bottom, the limiting baffle having a tape limiting groove; and a positioning pin installed on the vertical support. However, this patent does not address the issue of rapid tape cutting.

[0004] To address this, our company proposes a tape cutting tool and a tape marking machine using the tool. Summary of the Invention

[0005] The purpose of this invention is to provide a tape cutting tool and a tape marking machine using the tool, which can quickly cut the marked tape.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tape cutting tool and a tape marking machine using the tool are disclosed, comprising a rotating shaft, wherein a first slot for mounting a blade is provided in the rotating shaft, and first retaining rings for fixing the blade are provided at both ends of the rotating shaft.

[0008] Preferably, a second retaining ring is provided at both ends of the rotating shaft, and the side wall of the second retaining ring is provided with a second slot for installing the blade.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. DETAILED DESCRIPTION

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the tape marking machine proposed in this embodiment includes a support frame, which includes a main support 1 and a secondary support 2 hinged to the main support 1. A tape roller 5 is mounted on the main support 1, and tape 6 for marking is installed on the tape roller 5. During marking, one end of the tape 6 is adhered to the ground. As the support frame moves, the tape 6 rotates on the tape roller 5, achieving continuous marking on the ground. A guide pin 10 is provided at the lower front end of the main support 1 to prevent the marking from becoming skewed. A handle 3 is provided at the upper end of the main support 1 for easy pushing during marking. A front pressure roller 7 is provided at the lower part of the main support 1, and a rear pressure roller 8 is provided at the rear of the secondary support 2. This allows the marking machine to move smoothly and effortlessly. Simultaneously, the front pressure roller 7 further compacts the laid tape, reducing air bubbles. The rear pressure roller 8 is shorter, facilitating the turning of the marking machine, and also further compacts narrow tape. The support frame is equipped with a cutting tool 12 for cutting the tape. After the current indicator line is drawn, the tape 6 is cut to draw the next line.

[0028] A control handle 4 for controlling the rotation of the cutting blade 12 is provided on the upper part of the main support frame 1. The control handle 4 is connected to the cutting blade 12 via a wire-controlled steel cable 11. A return spring 9 is provided between the cutting blade 12 and the support frame to guide the cutting blade 12 to return to its original position. When it is necessary to cut the tape, squeezing the control handle 4 will cause the cutting blade 12 to rotate upward, cut the tape after contact, and release the control handle 4. Under the traction of the return spring 9, the cutting blade 12 returns to its original position, ready for the next cut. At the same time, returning to its original position can also avoid injury. In this embodiment, the control handle 4 is set as a handbrake.

[0029] like Figure 3 and Figure 4 As shown, the cutting tool 12 in this embodiment includes a rotating shaft 13 that passes through the main body support 1, and a blade 14 is provided on the side wall of the rotating shaft 13. The rotating shaft 13 can rotate upward or downward along the main body support 1 under the action of the wire rope 11 or the return spring 9.

[0030] The blade 14 can be a sharp, straight edge (similar to a kitchen knife) or a serrated edge. The serrated edge allows for more efficient cutting.

[0031] To facilitate tool assembly, a first slot 18 is provided inside the rotating shaft 13. After the blade 14 is inserted into the first slot 18, first retaining rings 17 are installed at both ends of the rotating shaft 13 to fix the blade 14. In this way, the rotating shaft 13 and the blade 14 will rotate synchronously.

[0032] The blade 14 has a clearance hole 15 for the main support 1 to pass through and a fixing hole 16 for fixing one end of the return spring 9. The other end of the return spring 9 is fixed to the guide pin 10. The clearance hole 15 allows the blade 14 to rotate smoothly. The end of the wire control cable 11 is fixed to the blade 14. When the control handle 4 is squeezed, the wire control cable 11 pulls the blade 14, thereby driving the rotating shaft 13 to rotate.

[0033] When using this device, push the support frame to move to mark the lines. After marking the lines, squeeze the control handle 4 to complete the cutting, while ensuring the flatness of the cut surface and reducing the workload of the operator.

[0034] Example 2

[0035] like Figure 5 As shown, in this embodiment, the structure of the tape marking machine is the same as that in Embodiment 1, except that the structure of the cutting tool 12 is different.

[0036] In Embodiment 1, because the shaft 13 is relatively long and slotting is difficult, this embodiment does not slot the shaft 13. Instead, second retaining rings 19 are installed at both ends of the shaft 13, and second slots 20 are formed on the side walls of the second retaining rings 19. The blade 14 is then inserted into the second slots 20 to complete the fixation. To prevent the blade 14 from falling off, two additional second retaining rings 19 are provided in the middle of the shaft 13 (i.e., the part in contact with the main support 1) to improve the clamping force.

[0037] The other structures in this embodiment are the same as in Embodiment 1.

[0038] Example 3

[0039] In this embodiment, the cutting tool 12 can be configured as a telescopic type. When the control handle 4 is squeezed, the cutting tool 12 extends out and returns to its original position under the action of the return spring 9 after the control handle 4 is released.

[0040] The other structures in this embodiment are the same as in Embodiment 1.

[0041] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way.
