DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 3 The utility model provides a new paper tube cutting machine, including a frame 1, on which two rollers 2 arranged in parallel and used to place paper tubes to be cut are installed, and both ends of the rollers 2 are connected with adjustment devices installed on the frame 1 and used to adjust the distance between the two rollers 2, and a shearing mechanism fixedly installed on the frame 1 and used to shear the paper tube to be cut placed on the roller 2 is provided above the roller 2, and the shearing mechanism includes a fixed frame 31, a fixed plate 32, a first driving member 33, a cutter 34 and a second driving member 35, the fixed frame 31 is fixed on the frame 1, the first driving member 33 is fixed on the fixed frame 31, and the fixed plate 32 is fixedly connected to the driving end of the first driving member 33, the cutter 34 is rotatably arranged on the fixed plate 32 and located above the paper tube to be cut, and the driving end of the second driving member 35 is connected to the cutter 34 for driving the cutter 34 to rotate.

[0020] In this embodiment, the first driving member 33 is a driving cylinder, and the second driving member 35 is a driving motor. The vertical position of the cutter 34 is adjusted based on the first driving member 33 so that the cutter 34 can adapt to paper tubes of different sizes, and the cutter 34 is driven to rotate based on the second driving member 35 to cut the paper tube to be cut. By arranging two rollers 2 with adjustable spacing on the frame 1 to support the paper tube to be cut, and adjusting the spacing between the two rollers 2 based on the adjustment device, paper tubes of different sizes can be cut and supported, which solves the technical problem of the need to replace the support shaft when cutting paper tubes of different sizes in the prior art, which is time-consuming and labor-intensive. Therefore, compared with the prior art, the paper tube cutting efficiency of this application is higher, the operation is simpler, the application range is wider, and the operation intensity of the operator is effectively reduced.

[0021] like Figure 1As shown, the adjustment device includes two threaded adjustment mechanisms symmetrically arranged at the two end portions of the two roller shafts 2, the threaded adjustment mechanism includes a guide rail 41 and a bidirectional threaded rod 42, the guide rail 41 is fixedly installed on the frame 1, and the end of each roller shaft 2 is fixedly connected to an adjustment plate 43 slidably arranged on the guide rail 41, each adjustment plate 43 is fixedly provided with at least one nut 44, and the two adjustment plates 43 are symmetrically located at the two ends of the bidirectional threaded rod 42, and the bidirectional threaded rod 42 is threadedly connected to the nut 44 on each adjustment plate 43 respectively for adjusting the distance between the two adjustment plates 43.

[0022] In this embodiment, two nuts 44 are fixed on each adjustment plate 43, and the adjustment plate 43 is fixed on the guide rail 41 based on the gravity of the roller shaft 2 itself; in other embodiments, threaded holes can be set on both the guide rail 41 and the adjustment plate 43, and the adjustment plate 43 can be fixed on the guide rail 41 by matching the external screw and the threaded hole. When the position of the adjustment plate 43 on the guide rail 41 needs to be adjusted, it is only necessary to take out the external screw.

[0023] In this embodiment, when the distance between the two roller shafts 2 needs to be adjusted, the operator rotates the bidirectional threaded rod 42. Since the bidirectional threaded rod 42 is threadedly connected to the nut 44, the two adjustment plates 43 fixedly connected to the nut 44 and located on the same side of the frame 1 move toward or away from each other along the guide rail 41. Therefore, by adjusting the position of the adjustment plate 43 on the guide rail 41, the distance between the two roller shafts 2 can be adjusted to be correspondingly reduced or expanded.

[0024] like Figure 1 As shown, each of the two-way threaded rods 42 is fixedly connected to a hand wheel 45 at one end away from the frame 1 .

[0025] In this embodiment, by providing a hand wheel 45 on the bidirectional threaded rod 42, it is greatly convenient for an operator to rotate the bidirectional threaded rod 42, thereby reducing the labor intensity of the operator.

[0026] like Figure 1-Figure 2 As shown, a protective cover 6 is also provided on the fixed plate 32 and covers the cutter 34. A notch 61 is provided at the lower portion of the protective cover 6 for the cutter 34 to contact the paper tube to be cut, and a paper powder transmission pipe 7 is provided between the dust collector 5 and the protective cover 6. The feed end of the paper powder transmission pipe 7 is through-connected with the inner cavity of the protective cover 6, and the discharge end of the paper powder transmission pipe 7 is connected with the feed end of the dust collector 5.

[0027] In this embodiment, the notch 61 is a quarter arc notch. By arranging the shield 6 on the cutter 34, the shield 6 is used to collect the paper dust generated during the cutting of the paper tube by the cutter 34 and transmit it to the dust collector 5 through the paper dust transmission pipe 7, which effectively reduces the pollution of the environment by the paper dust during the cutting process and, to a certain extent, reduces the harm of the paper dust to the operator.

[0028] like Figure 1 , Figure 3 As shown, the frame 1 is also provided with a light barrier protection device corresponding to the cutter 34, and the light barrier protection device includes a vertical pole 81, an infrared sensor 82 and an alarm (not shown in the figure). The vertical pole 81 is symmetrically arranged on the outer sides of both ends of the frame 1, and the infrared sensor 82 is fixed on the vertical pole 81 to detect whether someone accidentally enters the cutter working area, and the alarm is connected to the infrared sensor 82.

[0029] In this embodiment, an infrared sensor 82 is provided to detect in real time whether an operator has mistakenly entered the cutter working area. When the infrared sensor detects that someone has mistakenly entered the cutter working area, the alarm will sound an alarm prompting the detection result, thereby effectively ensuring the personal safety of the operator.

[0030] It also includes a control system (not shown in the figure), which is connected to the first driving member 33, the second driving member 35 and the dust collector 5 respectively.

[0031] In this embodiment, by setting a control system to control the start and stop of the first driving member 33, the second driving member 35 and the dust collector 5, the automation degree of the device is improved and the labor intensity of the operator is reduced. In actual application, the alarm and the infrared sensor 82 can also be connected to the control system respectively, and the control system receives the detection result of the infrared sensor 82 and issues an alarm prompt based on the detection result.

[0032] It should be noted that the contents not described in detail in this specification belong to the prior art known to those skilled in the art. The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the present application.
