[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] like Figure 1-Figure 4 As shown, this example provides a cardboard grooving tool, including: a base 100, a limiting mechanism 200, and a grooving mechanism 300.

[0022] Two recessed parts 101 are provided on both sides of the length direction of the base 100, and a bearing bar 102 moving along the length direction thereof is provided in the recessed parts 101; the limiting mechanism 200 includes clamping plates 201 respectively provided on both sides of the length direction of the base 100 and moving toward each other, which are used to limit the two sides of the paperboard, and a first baffle 202 and a second baffle 203 respectively located at both ends of the base 100 and moving along the length direction thereof are provided between the clamping plates 201, which are used to limit the two ends of the paperboard; the grooving mechanism 300 includes two rotating shafts 301 respectively provided on both sides of the length direction of the base 100 and moving along the width direction thereof, and three sliders 302 with adjustable spacing are sleeved on the rotating shafts 301, and the sliders 302 are provided with a plurality of cutters 303 arranged at intervals along the circumferential direction, and cooperate with the bearing bar 102 to cut grooves for the paperboard, wherein the two sliders 302 are located in the recessed parts 101 and move synchronously with the bearing bar 102, so as to avoid positional offset between the cutter 303 and the bearing bar 102, and ensure the smooth progress of the grooving operation.

[0023] Specifically, limiting grooves 103 are provided on both sides of the length direction of the base 100, and the lower end of the clamping plate 201 passes through the limiting groove 103 and is connected to the moving end of the bidirectional linear mechanism. The bidirectional linear mechanism is installed in the base 100. The two clamping plates 201 can be driven to move toward each other through the bidirectional linear mechanism, thereby limiting the two sides of the cardboard so that the cardboard is on the center line of the length direction of the base 100.

[0024] Specifically, a groove 104 is provided on the top surface of one end of the base 100, and the lower end of the first baffle 202 is slidably fitted in the groove 104 and sleeved on the first screw 204. The first screw 204 is rotatably installed in the groove 104, and one end passes through the base 100. The position of the first baffle 202 and the center of the base can be adjusted by rotating the first screw 204. While limiting one end of the cardboard, the position of the cardboard can also be adjusted, so that the cutters located at the center positions on both sides of the base 100 can cut the corresponding positions of the cardboard.

[0025] Specifically, two slide grooves 105 are provided at the other end of the base 100, and the bottoms of both ends of the second baffle 203 are slidably matched in the slide grooves 105. A guide rod 205 and a second screw rod 206 are provided in the slide groove 105. The guide rod 205 and the second screw rod 206 both pass through the second baffle 203. A spring 207 is sleeved on the guide rod 205. The two ends of the spring 207 are respectively connected to one end of the slide groove 105 close to the center of the base 100 and the second baffle 203, and are always in a stretched state. A nut is sleeved on the second screw rod 206, and the nut abuts against the second baffle 20 On the side close to the center of the base 100, the nut can be turned to make the second baffle plate 203 move toward the center of the base 100 under the action of the spring 207, so that the two ends of the paperboard can be limited. Before placing the paperboard on the base 100, the second baffle plate 203 can be pushed to move away from the center of the base 100, so that the paperboard can be placed between the first baffle plate 202 and the second baffle plate 203. Then, the second baffle plate 203 is loosened, and the second baffle plate 203 will abut against the nut, thereby completing the limitation of the two ends of the paperboard.

[0026] Specifically, according to the requirements of packaging boxes of different sizes, the length of the incision processed on the cardboard is also different, so the distance between the cutter 303 and the center of the base 100 needs to be adjusted, then the two ends of the rotating shaft 301 are rotatably installed on the movable plate 304, and one end is connected to the output end of the rotating motor 305, and the rotating motor 305 is installed on the movable plate 304. The rotating motor 305 drives the rotating shaft 301 to rotate, and then the cutter 303 can start to rotate to complete the cutting of the cardboard. The movable plate 304 is slidably installed on the side of the base 100. When the distance between the cutter 303 and the center of the base 100 needs to be adjusted, it is only necessary to move the movable plate 304 along the width direction of the base 100, and then lock it with screws.

[0027] Specifically, in order to facilitate the adjustment of the position of the cutter 303, a plurality of positioning grooves 306 are provided along the circumferential direction on the circumferential side of the rotating shaft 301, and the length direction of the positioning grooves 306 is parallel to the axis of the rotating shaft 301. A plurality of positioning pins are provided along the circumferential direction on the inner wall of the slider 302 located in the recessed portion 101, and the positioning pins are slidably fitted in the positioning grooves 306, thereby ensuring that the cutter 303 can move while enabling the cutter 303 to rotate with the rotating shaft 301.

[0028] Specifically, in order to ensure the cooperation between the cutter 303 and the supporting bar 102, two connecting rods 106 are provided at the outer end of the supporting bar 102, and the connecting rod 106 is provided with a through groove 107 along its length direction. The length direction of the through groove 107 is parallel to the width direction of the base 100, and annular grooves 307 are provided on both sides of the slider 302 located in the recessed portion 101. A block 308 is slidably fitted in the annular groove 307, and the lower end of the block 308 is slidably fitted in the through groove 107. When the supporting bar 102 moves along the length direction of the base 100, the block 308 moves synchronously with the supporting bar 102, thereby driving the slider 302 to move together, thereby adjusting the position of the cutter 303 and not affecting the movement of the rotating shaft 301.

[0029] Specifically, notches 108 are provided on both sides of the base 100 and the supporting bar 102, and the length direction of the notch 108 is parallel to the width direction of the base 100. The cutter 303 includes a semicircular segment and two straight segments connected to the ends of the semicircular segment, and one end of the straight segment is connected to the slider 302. When cutting the cardboard, the cutter 303 cooperates with the inner wall of the notch 108 to realize the processing of the cardboard cut.

[0030] More specifically, in order to ensure the consistency of the cardboard cutting process of the pillow, the bearing strips 102 located on the same straight line can be installed on the same connecting rod, and the connecting rod can be locked with screws.

[0031] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
