DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1—4, an embodiment of the utility model proposes a paper tube cutting device, including a workbench 1, a fixing component and a second mounting plate 3. A slide groove is opened on one side of the top of the workbench 1, and a first mounting plate 2 is slidably arranged on the slide groove. The first mounting plate 2 is provided with a cutting component for cutting the paper tube. The workbench 1 is provided with a driving component for driving the first mounting plate 2 to slide along the slide groove. The fixing component is arranged on the top of the workbench 1, and the fixing component is used to fix the paper tube. The second mounting plate 3 is arranged on one side of the top of the workbench 1 away from the first mounting plate 2. The first mounting plate 2 is fixedly connected to the second mounting plate 3 through a first connecting plate 4. The first mounting plate 2 is provided with a dust collecting component for collecting paper scraps generated when the paper tube is cut. In this embodiment, the first connecting plate 4 is located at the bottom of the workbench 1, and the two ends of the first connecting plate 4 are extended along the width direction of the workbench 1 and fixedly connected with the first mounting plate 2 and the second mounting plate 3. In order to make the movement of the first connecting plate 4 smoother, a guide groove can be provided at the bottom of the workbench 1 and a guide block can be provided on the first connecting plate 4. The slide groove is provided along the length direction of the workbench 1. When working, the paper tube to be cut is first fixed by the fixing component, and then the driving component is started. The driving component drives the first mounting plate 2 to move along the length direction of the slide groove, that is, to move along the length direction of the paper tube. In the process of moving the first mounting plate 2, the paper tube is cut by the cutting The cutting assembly cuts the paper tube. Since the second mounting plate 3 is fixed to the first mounting plate 2 by the first connecting plate 4, when the first mounting plate 2 moves, the second mounting plate 3 will move with the first mounting plate 2, so that the dust collecting assembly on the second mounting plate 3 always remains relative to the cutting assembly, thereby absorbing the paper scraps and dust generated when the cutting assembly cuts the paper tube. The dust collecting assembly moves synchronously with the cutting assembly to fully absorb the paper scraps and dust generated when the paper tube is cut, thereby preventing the paper scraps and dust from being scattered in the air and then inhaled by the workers, thereby significantly reducing the dust in the air of the workshop, improving fire safety while also ensuring the respiratory health of the workers.

[0022] like Figure 1 —4, further, the dust collection assembly includes: a dust hood 5, the dust hood 5 is fixedly arranged on the top of the second mounting plate 3, one end of a dust suction pipe 6 is connected to the dust hood 5, and the other end of the dust suction pipe 6 is connected to a negative pressure pump 7. When the device is working, the negative pressure pump 7 is started in advance, and the negative pressure pump 7 absorbs the paper dust scattered into the air when the paper tube is cut through the dust suction pipe 6. The dust hood 5 is in an expanded shape, which helps the dust suction pipe 6 to absorb the paper dust within the opening range of the dust hood 5.

[0023] like Figure 1—3, further, it also includes: an extension frame 8, one end of the extension frame 8 is fixedly arranged on the side wall of the bottom end of the dust hood 5 facing the first mounting plate 2, and a filter screen plate 9 is arranged on the top of the extension frame 8. In this embodiment, the extension frame 8 is arranged on one side of the bottom end of the dust hood 5, that is, the extension frame 8 is always directly below the paper tube cutting position, and the filter screen plate 9 is arranged on the top of the extension frame 8, so that the extension frame 8 and the filter screen plate 9 form a accommodating cavity. When the cutting assembly cuts the paper tube, some larger paper scraps and dust and some paper scraps and dust that are not absorbed by the dust suction pipe 6 will fall onto the extension frame 8 below it, and some paper scraps and dust will fall onto the filter screen plate 9 and gradually be sucked away by the dust suction pipe 6. The undifferentiated paper scraps and dust will pass through the filter screen plate 9 and enter the interior of the extension frame 8, so as to avoid the wind generated by the outside world from causing it to overflow into the air again. The interior of the extension frame 8 can be cleaned later by opening the filter screen plate 9. Preferably, a branch pipe can also be arranged to be inserted into the extension frame 8 to absorb the paper scraps and dust in the extension frame 8.

[0024] like Figure 1 As shown in FIG. 4 , further, a stop bar 10 is provided on the top of the extension frame 8. Since the second mounting plate 3 moves along with the first mounting plate 2 after each cutting action is completed, the stop bar 10 can prevent the paper scraps and dust on the filter screen plate 9 from falling from the edge of the filter screen plate 9 onto the workbench 1 during the movement.

[0025] like Figure 1 , 2 As shown in Figure 4, further, the driving assembly includes: a screw rod 11, the screw rod 11 is horizontally and rotatably arranged in the slide groove, a slider is fixedly arranged at the bottom of the first mounting plate 2, the slider is threadedly connected to the screw rod 11, and a first motor 12 is arranged on the side wall of the workbench 1, and the output end of the first motor 12 is inserted into the slide groove and fixedly connected to one end of the screw rod 11. When the first mounting plate 2 needs to move, the first motor 12 is started, and the first motor 12 drives the screw rod 11 to rotate, so that the slider threadedly connected to the screw rod 11 moves along the length direction of the slide groove, so that the first mounting plate 2 fixed to the slider moves with the slider, so that the cutting assembly on the first mounting plate 2 can cut different positions of the paper tube.

[0026] like Figure 1 , 2As shown in Figure 4, further, the fixing assembly includes: a third mounting plate 13, the third mounting plate 13 is vertically and fixedly arranged at one end of the workbench 1, a second motor 14 is fixedly arranged on the side wall of the third mounting plate 13, a rotating shaft 15 is fixedly arranged on the output end of the second motor 14 after passing through the third mounting plate 13, and a plurality of spring pieces 16 are evenly spaced on the circumferential outer wall of the rotating shaft 15. Specifically, the spring piece 16 is wavy, and when fixing the paper tube, one end of the paper tube is sleeved on the rotating shaft 15, specifically, the rotating shaft 15 is inserted into the hole of the paper tube, and when the rotating shaft 15 is inserted into the hole of the paper tube, the spring piece is compressed and abuts against the inner wall of the paper tube, so that the paper tube is fixed on the rotating shaft 15, preferably, when the cutting assembly cuts the paper tube, the second motor 14 drives the paper tube to rotate slowly, so that the circumferential outer wall of the paper tube contacts the cutting assembly when the paper tube rotates and is cut, and the force on the paper tube as a whole is relatively uniform and not easy to bend.

[0027] like Figure 1 —4, further, the cutting assembly includes: a mounting block 17 and a cutting machine 18, the mounting block 17 is slidably arranged on the first mounting plate 2, the cutting machine 18 is arranged on the top of the mounting block 17, and a cylinder 19 is also arranged on the first mounting plate 2, and the output end of the cylinder 19 is fixedly connected to the mounting block 17. The cutting machine 18 can be selected from the prior art, such as a structure in which a motor drives a saw blade to rotate, when the cutting machine 18 moves to the position to be cut of the paper tube following the first mounting plate 2, the cylinder 19 is started, and the cylinder 19 pushes the mounting block 17 toward the paper tube, so that the cutting machine 18 on the mounting block 17 moves toward the paper tube and finally cuts the paper tube, and after the cutting is completed, the cylinder 19 drives the mounting block 17 to return to its original position again, and at this time the first mounting plate 2 can move to the next position to be cut, so as to cut the paper tube back and forth.

[0028] like Figure 1 —4, further, it also includes a second connecting plate 20, the two ends of the second connecting plate 20 are fixedly connected to the first mounting plate 2 and the second mounting plate 3 respectively, and a support platform 21 is fixedly arranged on the top of the second connecting plate 20, and an arc groove is provided on the top of the support platform 21. Since the paper tube to be cut is relatively long, one end of the paper tube will be in a suspended state, and the suspended end of the paper tube is very easy to bend. The paper tube is supported by the arc groove on the support platform 21, which avoids bending at the part where the paper tube is to be cut. Since the support platform 21 is arranged on the second connecting plate 20, and the two ends of the second connecting plate 20 are fixed to the first mounting plate 2 and the second mounting plate 3 respectively, the support platform 21 can move with the first mounting plate 2 and the second mounting plate 3, so that the support platform 21 can always maintain support on one side of the part where the paper tube is to be cut, thereby ensuring the cutting quality of the paper tube by this device.

[0029] like Figure 1 and 4As shown, further, it also includes a plurality of balls 22, each of which is rotatably arranged in the arc groove. In this embodiment, the balls 22 are arranged at equal intervals along the arc segment direction of the inner wall of the arc groove. Due to the plurality of balls 22 arranged in the arc groove, the paper tube can move laterally or rotate more smoothly in the arc groove.

[0030] 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. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
