[0023] like Figure 1 As shown, the cardboard slotting machine includes a frame and a cardboard slotting tool device ( Figure 1 2 A), a tool beam 1 is mounted on the frame 9, such as Figure 2 and Figure 3 As shown, a tool guide rail 10 is installed on the tool beam 1, and a tool base 4 of the cardboard slotting tool device is slidably arranged on the tool guide rail 10 through a slider 40, so that the position of the cardboard slotting tool device on the tool guide rail 10 can be adjusted.

[0024] like Figure 3-Figure 5 As shown, the cardboard slotting tool device includes a slotting tool 3, a tool slide 5 and a tool base 4. The slotting tool 3 is installed on the tool slide 5. The tool slide 5 can be slidably arranged on the tool base 4. An adjusting motor 2 is installed on the tool base 4. The output end of the adjusting motor 2 is connected with a screw rod 20. The tool slide 5 is provided with a nut 21. The screw rod 20 and the nut 21 are threadedly connected. The adjusting motor 2 can drive the tool slide 5 to move forward and backward on the tool base 4 to achieve fine adjustment of the front and rear position of the slotting tool 3. When the front and rear position of the slotting tool 3 needs to be adjusted, the output end of the adjusting motor 2 drives the screw rod 20 to rotate, and the screw rod 20 drives the tool slide 5 to move forward and backward on the tool base 4 through the nut 21. Since the slotting tool 3 is installed on the tool slide 5, the front and rear position of the slotting tool 3 can be automatically adjusted to meet the requirements of different slotting depths of the cardboard, which greatly facilitates the operation of adjusting the tool.

[0025] In order to lock the cardboard slotting tool device on the tool guide rail 10, as shown in FIG. Figure 6As shown, the tool base 4 is provided with a positioning column 8 that can move up and down, and the tool slide 5 is provided with a locking block 6, which has an action slope 61 that can act on the positioning column 8 and move the positioning column 8 downward; the bottom of the locking block has a positioning plane 63, and the positioning plane 63 is located on the lower side of the action slope 61. When it is necessary to lock the cardboard slotting tool device, the adjustment motor 2 drives the tool slide 5 to move forward, and the locking block 6 also moves forward synchronously, so that the action slope 61 of the locking block 6 continuously presses down on the positioning column 8 and moves the positioning column 8 downward, until the positioning plane 63 of the locking block 6 acts on the positioning column 8, so that the positioning column 8 acts on the tool beam 1 to achieve locking. Since the positioning column 8 is arranged on the tool base 4, the tool base 4 is fixed and the cardboard slotting tool device will not move left and right on the tool beam 1. After the cardboard slotting tool device is locked, the adjustment motor 2 can continue to drive the tool slide 5 to move forward or backward to fine-tune the front and rear positions of the slotting tool 3. During this process, the positioning column 8 always presses against the positioning plane 63 of the locking block 6.

[0026] Through the above structure, two functions are realized with only one motor: first, after the position of the cardboard slotting tool device on the tool guide rail 10 is determined, the motor drive can lock it to prevent it from sliding left and right during slotting; second, after the position of the slotting tool device on the tool guide rail 10 is locked, the motor drive can adjust the front and rear position of the slotting tool 3. The benefits of this structure are that the structure is significantly simplified, the manufacturing cost is reduced, and automation is improved.

[0027] In order to reduce the friction between the positioning column 8 and the locking block 6, as shown in FIG. Figure 6 As shown, a steel ball 80 is embedded in the upper end of the positioning column 8, and the steel ball 80 acts on the locking block 6. Since the steel ball 80 and the acting inclined surface 61 are in point contact, the friction is smaller, the wear is less, and the noise is also lower.

[0028] In order to reduce the hard contact between the positioning column 8 and the tool beam 1, as Figure 7 As shown, the positioning column 8 includes a main column 81 and an action column 82. The action column 82 is movably sleeved on the lower part of the main column 81. A spring 83 is arranged between the main column 81 and the action column 82. The steel ball 80 is arranged on the upper end of the main column 81. Since the action column 82 is retractable through the spring 83, the action column 82 has a certain buffering effect on the tool beam 1, thereby protecting the positioning column 8 and the tool beam 1.

[0029] like Figure 8As shown, the slotting tool 3 includes a shank 33, which is connected to a shank seat 34, and the shank 33 is connected to the side of the shank seat 34; the front end of the shank 33 is connected to a shank seat 32 for mounting the blade 31. Since the shank 33 is connected to the side of the shank seat 34, there is no need to consider the original groove problem, and the shank 33 only needs to be placed against the side of the shank seat 34 (with the side of the shank seat 34 as the reference plane) and connected to the shank seat 34. This method is not only convenient for the installation of the shank 33, but also prevents the shank 33 from moving left and right during use, ultimately ensuring the slotting accuracy of the blade 31.

[0030] In order to connect the arbor 33 to the arbor seat 34, a screw hole 340 is provided on the arbor seat 34, and the arbor 33 has a long hole 340. The arbor 33 is connected to the arbor seat 34 by a fixing bolt (the fixing bolt is not shown), and the fixing bolt passes through the long hole 330 of the arbor 33 and is threadedly connected in the screw hole 340 of the arbor seat 34. With this structure, the arbor 33 can be easily connected by simply positioning the arbor 33 and then tightening the fixing bolt.

[0031] As mentioned above, the knife bar 33 needs to be positioned before it can be fixed, and for this purpose, a positioning block 35 is provided on the knife bar seat 34, and the knife bar 33 has a first positioning groove 331, and the positioning block 35 is located in the first positioning groove 331. When positioning, just lean the knife bar 33 against the side of the knife bar seat 34, and then let the positioning block 35 enter the first positioning groove 331 of the knife bar 33, and then move the knife bar 33 on the side of the knife bar seat 34, so that the positioning block 35 interacts with the inner wall of the first positioning groove 331, so that the positioning is completed, and then the fixing bolt can be tightened.

[0032] In order to facilitate the adjustment of the position of the knife bar 33, the positioning block 35 is connected to the connecting seat 36 so as to be movable forward and backward, and the connecting seat 36 is connected to the knife bar seat 34. By adjusting the position of the positioning block 35, the positioning position of the knife bar 33 is also changed accordingly.

[0033] Since the positioning block 35 only limits the movement of the knife bar 33 in one direction, and the fixing bolt can hardly ensure that the knife bar 33 does not move on the side of the knife bar seat 34, in order to ensure that the knife bar 33 does not move on the side of the knife bar seat 34, a positioning screw 37 is provided on the knife bar seat 34, and the positioning screw 37 is threadedly connected with the knife bar 33. The knife bar 33 can be moved relative to the positioning block 35 through the positioning screw 37, so that the positioning screw 37 acts on the knife bar 33 from one end of the knife bar 33, and the positioning block 35 acts on the knife bar 33 from the other end of the knife bar 33, so that the knife bar 33 is ensured not to move on the side of the knife bar seat 34.

[0034] In order to facilitate quick installation, a slot 341 is provided on the knife bar seat 34, and the positioning screw 37 is rotatably stuck in the slot 341. When the knife bar 33 needs to be removed, just loosen the fixing bolt, and lift the knife bar 33 and the positioning screw to the side to remove the knife bar 33; and when the knife bar 33 needs to be installed, just lean the knife bar 33 against the side of the knife bar seat 34, then the positioning screw 37 is stuck in the slot 341, and then let the positioning block 35 position well, and then tighten the positioning screw 37, and finally tighten the fixing bolt. In this way, the knife bar 33 can be firmly fixed and will not move in the horizontal and vertical directions.
