In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, the following improvement plan is proposed.

[0027] More specifically:

[0028] like Figures 1 to 5 As shown;

[0029] Combining the above:

[0030] Two symmetrically arranged protective components are installed on both sides of the conveyor 2 of the anti-falling cardboard cutting device, and the protective components include a fixed box 3 fixed on the side of the conveyor 2, and a protective plate 4 is provided on the side of the fixed box 3 away from the conveyor 2. Two guide rods 5 are fixed to the outer wall of the protective plate 4. The guide rods 5 penetrate the surface of the fixed box 3 and extend into the fixed box 3, and are slidably connected to the fixed box 3. An electric telescopic rod A6 fixed in the protective plate 4 is provided between the two guide rods 5, and the output end of the electric telescopic rod A6 penetrates the fixed box 3 and is fixedly connected to the fixed box 3.

[0031] In this embodiment: during the cardboard transmission operation, the conveyor 2 contacts the middle of the cardboard, and the cardboard is driven by the conveyor 2 to move toward the cutting machine 1. The protective plate 4 limits the side of the cardboard, and the anti-slip plate 7 above the protective plate 4 covers the top of the edge of the cardboard. The two sets of protective components limit the two sides and the top of the cardboard so that it can only move along the transmission direction to prevent the cardboard from falling off. When transmitting cardboards of different sizes, by starting the electric telescopic rod A6, the protective plate 4 can be driven to slide along the guide rod 5 to adjust the distance between the two protective plates 4, and this adjustment method will not affect the transmission of the cardboard by the conveyor 2, so that the utility model can be applied to cardboards of different sizes.

[0032] Going further:

[0033] In an optional embodiment, the protection component also includes a plurality of clamping mechanisms, each group of clamping mechanisms includes a screw rod 8 vertically penetrating the anti-drop plate 7, the screw rod 8 is slidably connected to the anti-drop plate 7, a clamping wheel 9 is fixed to the bottom end of the screw rod 8, a section of the screw rod 8 located above the anti-drop plate 7 is threadedly connected to a handle 10, and a spring 11 is installed between the clamping wheel 9 and the anti-drop plate 7 and is sleeved on the anti-drop plate 7.

[0034] In this embodiment: since the cardboard is relatively soft, through this design, when the cardboard is on the surface of the conveyor 2, the operator turns the handle 10, and the screw rod 8 moves downward under the elastic force of the spring 11, driving the clamping wheel 9 to move to the surface of the cardboard. During the cardboard transmission process, the clamping wheel 9 contacts the cardboard, further limiting the position of the cardboard, so that the cardboard and the conveyor 2 are stably fitted, avoiding the situation where the cardboard is bent and vacated, and preventing the cardboard from bouncing up when cutting the cardboard.

[0035] Going further:

[0036] In an optional embodiment, the protection plate 4 is an L-shaped plate structure, and a plurality of transverse rollers 401 and vertical rollers 402 are installed on the inner surface of the protection plate 4 .

[0037] In this embodiment: through this design, the transverse roller 401 and the vertical roller 402 reduce the friction between the paperboard and the protective plate 4, improve the smoothness of the paperboard transmission, and avoid the wear of the paperboard.

[0038] It should be noted that the bottom end of the vertical roller 402 is embedded in the protective plate 4 to prevent a lateral gap that can jam the edge of the cardboard from appearing at the vertical roller 402 .

[0039] Going further:

[0040] like Figure 5 As shown;

[0041] In an optional embodiment, a limiting sliding groove 801 is provided on the outer side wall of the screw rod 8 , and a through hole matching the limiting sliding groove 801 is provided on the surface of the anti-slip plate 7 .

[0042] In this embodiment: through this design, the limiting slide groove 801 prevents the screw rod 8 from rotating itself, so that the clamping wheel 9 is in a stable state and it is convenient for the user to rotate the handle 10.

[0043] Going further:

[0044] In an optional embodiment, a storage assembly is provided on the side of the cutting machine 1 away from the conveyor 2, and the storage assembly includes a storage frame 20. Four electric telescopic rods B21 are fixed to the bottom of the storage frame 20, and a blocking rod 22 that penetrates the storage frame 20 is provided on the side of the storage frame 20. The blocking rod 22 is an L-shaped rod structure, and the blocking rod 22 is slidably connected to the storage frame 20.

[0045] In this embodiment, when the cardboard is cut, the subsequent cardboard pushes out the cut cardboard, and the cut cardboard can fall into the storage frame 20, so that the cardboard can be stored after cutting, and the operator does not need to watch for a long time. The blocking rod 22 can be slidably adjusted so that the storage assembly can store cardboards of different lengths, which is convenient to use.

[0046] It should be noted that there is a large damping (static friction) between the blocking rod 22 and the storage frame 20, and the blocking rod 22 will not slide due to the advancement of the cardboard.

[0047] Going further:

[0048] In an optional embodiment, an ultrasonic sensor is installed on the surface of the blocking rod 22 .

[0049] In this embodiment: through this design, when cardboard falls on the surface of the storage frame 20, the ultrasonic sensor can detect the height of the cardboard stack, and cooperate with the four electric telescopic rods B21 to adjust the height of the storage frame 20 so that the height of the cardboard on the storage frame 20 is lower than the surface of the conveyor 2, which can prevent the cardboard stacking from affecting the cutting operation. After a certain amount of cardboard is stored, the cut cardboard is transferred by the staff.

[0050] The working principle and use process of the utility model are as follows: during the cardboard transmission operation, the conveyor 2 contacts the middle of the cardboard, and the cardboard is driven by the conveyor 2 to move toward the cutting machine 1. The protective plate 4 limits the side of the cardboard, and the anti-slip plate 7 above the protective plate 4 covers the upper edge of the cardboard. The operator turns the handle 10, and the screw rod 8 moves downward under the elastic force of the spring 11, driving the clamping wheel 9 to move to the surface of the cardboard. During the cardboard transmission process, the clamping wheel 9 contacts the cardboard and further limits the cardboard, so that the cardboard and the conveyor 2 are stably fitted to avoid the cardboard bending and vacating, and the cardboard can be prevented from bouncing up when cutting the cardboard. The two sets of protective components limit the two sides and the top of the cardboard so that it can only move along the transmission direction to prevent the cardboard from falling off. The horizontal roller 401 and the vertical roller 402 reduce the friction between the cardboard and the protective plate 4, improve the smoothness of the cardboard transmission, and avoid Avoid cardboard wear. When transmitting cardboards of different sizes, by starting the electric telescopic rod A6, the protective plate 4 can be driven to slide along the guide rod 5 to adjust the distance between the two protective plates 4. This adjustment method will not affect the transmission of the cardboard by the conveyor 2, so that the utility model can be applied to cardboards of different sizes. After the cardboard is cut, the subsequent cardboard will push the cut cardboard out, and the cut cardboard can fall into the storage frame 20. The ultrasonic sensor can detect the height of the cardboard stacking. With the four electric telescopic rods B21, the height of the storage frame 20 is adjusted so that the height of the cardboard on the storage frame 20 is lower than the surface of the conveyor 2, which can avoid the cardboard stacking affecting the cutting operation. After storing a certain amount, the cut cardboard is transferred by the staff, and the operating staff does not need to watch for a long time. The blocking rod 22 can be slidably adjusted so that the storage component can store cardboards of different lengths, which is convenient to use.
