[0012] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 and Figure 2As shown, the utility model provides a paper tube cutting device, including a base plate 1, a turntable 2 is arranged above the base plate 1, a No. 1 motor 21 for driving the turntable 2 to rotate is arranged on the base plate 1, a group of conical connecting columns 3 are fixed to the outer ring surface of the turntable 2, the thicker end of the connecting column 3 is fixed to the turntable 2, and the thinner end of the connecting column 3 is fixed to a connecting plate 31, and a liftable abutment plate 33 is arranged above and below the connecting plate 31, and two electric telescopic rods 32 for driving the two abutment plates 33 are arranged on the connecting plate 31; a liftable lifting plate 5 is arranged on one side of the turntable 2, a hydraulic rod 51 for driving the lifting plate 5 is arranged on the base plate 1, a No. 2 motor 53 is arranged on the inner side of the lifting plate 5, a cutting blade 52 located above a connecting column 3 is fixed on the rotating shaft of the No. 2 motor 53, and a No. 1 automatic telescopic rod 54 for driving the No. 2 motor 53 to move toward the turntable 2 is arranged on the lifting plate 5.

[0014] like Figure 1 and Figure 3 As shown, a fixed plate 4 connected to the bottom of the turntable 2 is provided below the connecting column 3, and a No. 2 automatic telescopic rod 41 is fixed on the fixed plate 4. The telescopic end of the No. 2 automatic telescopic rod 41 is fixed with a moving block 42 slidably connected to the fixed plate 4, and a vertical plate 43 is fixed on the top of the moving block 42. The top of the vertical plate 43 is hinged with a baffle 44 corresponding to the thinner end of the connecting column 3. The top surface of the vertical plate 43 is located below the connecting column 3. When the paper tube is sleeved on the connecting column 3, the baffle 44 can be in an upright state. The hinge of the baffle 44 and the vertical plate 43 is located on the side of the baffle 44 and the vertical plate 43 close to the turntable 2. When the baffle 44 is erected, the second automatic telescopic rod 41 can be started to make the moving block 42 drive the baffle 44 to move toward the paper tube through the vertical plate 43, so that the end of the paper tube away from the turntable 2 will press against the baffle 44, and the baffle 44 can further play a role in fixing the paper tube; when the paper tube is cut, when it is necessary to remove the paper tube from the connecting column 3, the baffle 44 is folded to change the baffle 44 from a vertical state to a horizontal state.

[0015] like Figure 1 and Figure 3 As shown, the top of the vertical plate 43 is inlaid with a magnet 45 in contact with the bottom of the baffle 44, and the baffle 44 is made of steel. When the baffle 44 is in a vertical state, the magnet 45 can absorb the baffle 44, increase the stability of the baffle 44, and make the baffle 44 always stay vertical.

[0016] like Figure 1As shown, the main body of the No. 1 motor 21 is fixed on the bottom plate 1, and a column 22 connected to the axis of the bottom of the turntable 2 is fixed on the rotating shaft of the No. 1 motor 21, and a battery 23 is fixed on the column 22; a support rod 24 slidably connected to the bottom plate 1 is fixed at the bottom of the turntable 2. After starting the No. 1 motor 21, the rotating shaft of the No. 1 motor 21 drives the turntable 2 to rotate through the column 22, which can change the position of the connecting column 3, and the number of connecting columns 3 on the turntable 2 is at least four; the battery 23 can supply power to the electric telescopic rod 32, and the support rod 24 can increase the stability of the turntable 2. An annular slide groove is provided on the bottom plate 1, and the bottom end of the support rod 24 is slidably connected in the slide groove.

[0017] like Figure 1 As shown, the lifting plate 5 is L-shaped, and a straight-line opening is provided at the top of the lifting plate 5. A moving rod 55 is slidably connected in the opening. The telescopic end of the No. 1 automatic telescopic rod 54 is fixed to the moving rod 55, and the end of the moving rod 55 away from the No. 1 automatic telescopic rod 54 is fixed to the main body of the No. 2 motor 53. The fixed end of the No. 1 automatic telescopic rod 54 is fixed to the top surface of the lifting plate 5. After the No. 1 automatic telescopic rod 54 is started, the telescopic end of the No. 1 automatic telescopic rod 54 can drive the moving rod 55 to move left or right in the opening at the top of the lifting plate 5 (in degrees). Figure 1 The movable rod 55 can drive the cutting blade 52 to move through the No. 2 motor 53, so as to adjust the position of the cutting blade 52 according to the length of the paper tube and accurately cut the paper tube; the fixed end of the hydraulic rod 51 is fixed on the bottom plate 1, and the telescopic end of the hydraulic rod 51 is fixed to the bottom end of the lifting plate 5. After starting the hydraulic rod 51, the lifting plate 5 can drive the cutting blade 52 to move upward or downward.

[0018] like Figure 1As shown, a collecting box 6 located below the cutting blade 52 is placed on the bottom plate 1, a partition 61 is fixed inside the collecting box 6, the upper half of the partition 61 is inclined, and the lower half of the partition 61 is vertically arranged; a fixing rod 7 is fixed on the lifting plate 5, a pressing plate 71 is fixed to the bottom end of the fixing rod 7, the top surface of the pressing plate 71 is inclined, and the pressing plate 71 is located between the vertical part of the partition 61 and the inner wall of the collecting box 6. After the paper tube is cut by the cutting blade 52, the cut part of the paper tube can fall into the collecting box 6 and be collected. The setting of the partition 61 can make the paper tube fall on the inclined surface of the partition 61, slide downward, and fall into the side of the partition 61 away from the turntable 2 (between the side of the inner wall of the collecting box 6 away from the turntable 2 and the partition 61). When the subsequent hydraulic rod 51 drives the lifting plate 5 to move downward, the fixed rod 7 drives the pressing plate 71 to move downward with the lifting plate 5, squeezes the paper tube in the collecting box 6, and compresses the paper tube to store more paper tubes, which is also convenient for subsequent staff to recycle the paper tubes; the top surface of the pressing plate 71 is set at an angle, which can also prevent the paper tubes from piling up on the top surface of the pressing plate 71, so that the paper tubes falling on the top surface of the pressing plate 71 can slide into the collecting box 6.

[0019] When in use, the paper tube is put on the connecting column 3 so that the connecting plate 31 is located on the inner side of the paper tube. When the outer wall of the connecting column 3 contacts the inner wall of the paper tube, the two electric telescopic rods 32 are started to move the two abutting plates 33 away from each other, respectively abutting the top and bottom of the paper tube to fix the paper tube; then the first automatic telescopic rod 54 is started to adjust the position of the cutting blade 52 so that the cutting blade 52 is located just above the part of the paper tube that needs to be cut, and then the second motor 53 is started to drive the cutting blade 52 to rotate, and then the hydraulic rod 51 is started to make the lifting plate 5 carry The movable cutting blade 52 moves downward so that the cutting blade 52 cuts the paper tube; during the paper tube cutting process, the staff can fix another paper tube to be cut on other connecting columns 3 according to the above operation. When the previous paper tube is cut, the No. 1 motor 21 is started to drive the turntable 2 to rotate so that the paper tube to be cut is located directly under the cutting blade 52, and the cut paper tube is moved away from directly under the cutting blade 52. When the paper tube to be cut is cut, the staff can remove the cut paper tube and replace it with a new paper tube to be cut.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
