[0020] In one embodiment, such as Figure 2 , Figure 6 As shown, this application proposes a roll wrapping layer cutting device, which includes a body 205. The body 205 can be a one-piece structure or it can be made of several parts spliced ​​and assembled. As an optional embodiment, a part of the body 205 can be made into the shape of a handle to facilitate gripping and use.

[0021] A first guide bar 201, a second guide bar 208, and a pressure bar 203 are connected to the main body 205. Specifically, the first guide bar 201 is located below the pressure bar 203, and the first guide bar 201 and the pressure bar 203 are arranged alternately to form a first space 204. It should be noted that the width of the first guide bar 201 and the pressure bar 203 should not be too large or too small.

[0022] A first cutter 302 is installed in the first space 204. The orientation of the first cutter 302 should meet the following requirements: with the end of the first guide bar 201 away from the body 205 as the head end, the blade of the first cutter 302 faces the head end.

[0023] The first guide bar 201 can be inserted between the wrapping layer 102 to be cut and the roll material 101. The cutting device is moved, and the wrapping layer 102 comes into contact with the blade of the first cutter 302, and the wrapping layer 102 is cut.

[0024] A second space 206 is formed between the second guide bar 208 and the body 205, and a second cutter 301 is installed in the second space 206.

[0025] The orientation of the second cutter 301 meets the following requirements: with the end of the second guide bar 208 away from the body 205 as the tail end, the blade of the second cutter 301 faces the tail end.

[0026] The second guide bar 208 can be inserted between the wrapping layer 102 to be cut and the roll material 101, and the cutting device is moved so that the wrapping layer 102 comes into contact with the blade of the second cutter 301 and the wrapping layer 102 is cut.

[0027] The tail end of the first guide bar 201 is connected to the body 205, the head end of the second guide bar 208 is connected to the body, and the second guide bar 208 can be approximately parallel to the first guide bar 201. The lower end face of the first guide bar 201 is flush with the lower end face of the second guide bar 208.

[0028] Generally, the first guide bar 201 is longer and the second guide bar 208 is shorter, so that the cutting device proposed in this application can be applied to a variety of working conditions.

[0029] When using it, firstly as follows Figure 9 As shown, the second guide strip 208 is inserted between the end face of the roll 101 and the wrapping layer 102, thereby cutting the wrapping layer 102 radially. When the wrapping layer 102 is cut to the junction of the radial and axial directions of the roll, then... Figure 10As shown, the first guide bar 201 is then inserted between the side of the roll 101 and the wrapping layer 102, while the pressure bar 203 presses down on the outer side of the wrapping layer 102, pushing the cutting device so that the first cutter 302 in the gap between the wrapping layer 102 and the surface of the roll 101 moves along the roll axis, thereby cutting the wrapping layer 102.

[0030] When the first cutting blade 302 moves, the hand can cooperate with the pressure bar 203. While the pressure bar 203 guides the sliding, it can press down on the part of the wrapping layer 102 to be cut. The hand lifts the cut wrapping layer 102, so that the pressure point and the part of the wrapping layer 102 lifted by the hand are taut. The taut wrapping layer 102 is easier to cut.

[0031] In order to ensure that the wrapping layer 102 can smoothly contact the cutting edge of the first cutter 302, as an optional implementation, such as Figure 2 As shown, a pair of guide vanes 207 are installed in the first space 204, and the pair of guide vanes 207 are located on both sides of the first cutter 302.

[0032] The guide vane 207 has a bevel 207-1 at the head end. The bottom of the bevel 207-1 is located on the surface of the first guide strip 201, and the top of the bevel 207-1 is located on the surface of the pressure strip 203, so that the cutting edge of the first cutter 302 is within the angle range formed by the bevel 207-1 and the lower surface of the pressure strip 203.

[0033] When the first cutter 302 moves along the axial direction of the roll material in the gap between the wrapping layer 102 and the surface of the roll material 101, the inclined surface 207-1 provided on the guide plate 207 can guide the cut opening of the wrapping layer 102 to the cutting edge of the first cutter 302 at the inclination angle of the inclined surface 207-1.

[0034] Optionally, such as Figure 3 As shown, the inclination angle of the inclined plane 207-1 is denoted as α, and the value of α ranges from 15° to 85°, such as 15°, 19°, 20°, 26°, 35°, 45°, 60°, 72°, or 85°, etc.

[0035] To ensure smooth contact between the wrapping layer 102 and the cutting edge of the second cutter 301, as an optional implementation, the lower end of the second cutter 301 is fitted against the surface of the second guide strip 208. In this case, there are no dead angles in the cutting, allowing the entire wrapping layer 102 to be cut off. As another optional implementation, a groove can be provided on the second guide strip 208, with the lower end of the second cutter 301 extending into the groove, thereby eliminating dead angles in the cutting.

[0036] In one alternative embodiment, the first cutter 302 is circular, and the cutting device also includes a fastening device. When it is necessary to cut the wrapping layer 102, the first cutter 302 can be restricted from rotating by the fastening device, thus fixing the first cutter 302. When the fastening device is released from its restriction on the first cutter, the first cutter can rotate. When the cutting edge of the first cutter 302 becomes dull, the first cutter 302 can be rotated to adjust the cutting edge used for cutting the wrapping layer 102, thereby enabling the first cutter 302 to be used multiple times. After the cutting edge position of the first cutter 302 is adjusted, the first cutter 302 is fixed by the fastening device again, so that the first cutter 302 will not rotate during operation.

[0037] For the fastening device, in one alternative embodiment, such as Figure 4 , Figure 5 As shown, the main body 205 is provided with a mounting guide groove 306, the upper part of the first cutter 302 is located in the mounting guide groove 306, and the lower part of the first cutter 302 is located in the first space 204.

[0038] The fastening device includes a pressure plate 303, which is located in the mounting guide groove 306 and fits against the first cutter 302. The fastening device also includes a connector 304, which comprises three sections: a pressure plate portion 304-1, a middle portion, and an external thread portion 304-2. The middle portion passes through the through holes provided in the first cutter 302 and the pressure plate 303. The pressure plate portion 304-1 fits against the side of the pressure plate 303 away from the first cutter 302. The external thread portion 304-2 extends to the side of the first cutter 302 away from the pressure plate portion 304-1 and extends out of the body 205.

[0039] The mounting guide groove 306 has at least two inner grooves with different inner diameters, one of which has a larger inner diameter than the other. The upper part of the first cutting tool 302 and the pressure plate 303 are placed in the inner groove with the larger inner diameter, and the external threaded part 304-2 extends out of the inner groove with the smaller inner diameter.

[0040] The external threaded portion 304-2 extending out of the body 205 is connected to a nut 305.

[0041] When the first cutter 302 needs to be rotated, the nut 305 can be loosened so that the pressure plate 303 is no longer tightly pressed against the first cutter 302, at which point the first cutter 302 can rotate. When the first cutter 302 needs to be fixed, the nut 305 is tightened so that the pressure plate 303 is pressed tightly against the first cutter 302, and the first cutter 302 is clamped between the inner wall of the mounting guide groove and the pressure plate 303, at which point the first cutter 302 cannot rotate.

[0042] As an optional implementation, both the first guide strip 201 and the pressure strip 203 are elastic and capable of elastic deformation. For example... Figure 7 As shown, Figure 7 (a) shows the case where the first guide bar 201 and the pressure bar 203 do not undergo elastic deformation. Figure 7 (b) shows the situation when the first guide bar 201 and the pressure bar 203 undergo elastic deformation and bend downwards. Figure 7 (c) shows the situation when the first guide bar 201 and the pressure bar 203 undergo elastic deformation and bend upward.

[0043] Since the wrapping layer 102 is flexible, the elastic first guide strip 201 and pressure strip 203 can ensure that the wrapping layer 102 to be cut is always pressed between the first guide strip 201 and pressure strip 203, which is conducive to cutting the wrapping layer 102.

[0044] To facilitate the insertion of the first guide strip 201 and the second guide strip 208 between the wrapping layer 102 and the roll material 101, as an optional implementation, the ends of the first guide strip 201 and the second guide strip 208 that are opposite to the body 205 are both triangular, and the ends are chamfered for a smooth transition. This facilitates the insertion of the guide strips between the wrapping layer 102 and the roll material 101 while avoiding puncturing the roll material 101.

[0045] In addition, such as Figure 8 As shown, a guide rib 202 is installed at the end of the first guide bar 201 away from the body 205, and a first arc-shaped protrusion 202-1 is provided on the side of the guide rib 202 away from the pressure bar 203. The first arc-shaped protrusion 202-1 can not only avoid damage to the roll material 101 when inserted between the wrapping layer 101 and the roll material 101, but also reduce the resistance of the guide insertion.

[0046] Optionally, the pressure bar 203 is provided with a second arc-shaped protrusion 203-1 facing the first guide bar 201. For example, the second arc-shaped protrusion 203-1 can be formed by bending the pressure bar 203. The second arc-shaped protrusion 203-1 serves both to press the wrapping layer 102 to be cut and to guide the smooth flow of the arc.

[0047] In addition, as an optional embodiment, mounting holes 209 can be provided on the main body 205 so that auxiliary devices such as marking laser rulers can be installed.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
