[0032] like Figure 1 As shown, an embodiment of one aspect of the utility model provides a circular knife machine, including a circular knife machine body 1 and a cutting waste collection device, the cutting waste collection device includes a material receiving mechanism 2 and a waste cutting mechanism 3 arranged on the top of the circular knife machine body 1, the material receiving mechanism 2 is fixed to the top of the circular knife machine body 1 by a bracket 26, and multiple material receiving mechanisms 2 can be arranged; the waste cutting mechanism 3 is welded to one side of the top of the circular knife machine body 1 through a base plate 35, and the cutting waste collection device also includes a recycling box 5 arranged on one side of the circular knife machine body 1 close to the waste cutting mechanism 3.

[0033] Specifically, in this embodiment, the circular knife machine body 1 can be used to perform processing in accordance with the existing technology.

[0035] like Figure 2 As shown, it shows a specific schematic diagram of the receiving mechanism 2 in the waste cutting and collecting device. In this embodiment, the receiving mechanism 2 includes a first active roller 21, a first driven roller 22 abutting against the first active roller 21, and a first driving motor 23 connected to the first active roller 21; the first active roller 21 and the first driven roller 22 are used to clamp the waste belt 4 led out from the circular knife machine, and the first driving motor 23 is used to drive the first active roller 21 to rotate, so that the first active roller 21 drives the first driven roller 22 to rotate simultaneously, and then the waste belt 4 clamped between the first active roller 21 and the first driven roller 22 is squeezed out of the receiving mechanism 2, and the first active roller 21 and the first driven roller 22 are provided with gears at both ends. The first active roller 21 starts to rotate under the transmission of the first driving motor 23, and the first active roller 21 is meshed with the first driven roller 22, driving the first driven roller 22 to rotate simultaneously, and the middle of the first active roller 21 and the first driven roller 22 is in contact with the waste belt 4, which is used to clamp the waste belt 4.

[0036] Specifically, in this embodiment, the second active roller 21 and the second driven roller 22 can clamp the waste belt 4 and then start to rotate.

[0037] Specifically, in the present embodiment, the material receiving mechanism 2 further includes a bracket 26, which is fixed to the top of the circular knife machine body 1 through the bracket 26, and the first drive motor 23 is transmission-connected to the first active roller 21 through the bracket 26, and the first active roller 21 and the first driven roller 22 are arranged on the bracket 26 through a rotating shaft, and a first pressure-adjusting hand wheel 24 for adjusting the degree of tightening between the first active roller 21 and the first driven roller 22 is arranged at the bottom of the bracket 26, and the first pressure-adjusting hand wheel 24 is fixedly connected to the first driven roller 22, and is used to control the first driven roller 22 to approach or move away from the first active roller 21.

[0038] Specifically, in this embodiment, the first driven roller 22 and the first pressure regulating hand wheel 24 are connected to a movable plate arranged on the bracket 26, and the movable plate and the bracket 26 are detachably connected. A pressure sensor 25 is arranged on the movable plate between the first driven roller 22 and the first pressure regulating hand wheel 24 for detecting the pressure of the first pressure regulating hand wheel 24.

[0039] like Figure 3 and Figure 4As shown, it shows a specific structural schematic diagram of the waste cutting mechanism 3 in the waste cutting and collecting device. In this embodiment, the waste cutting mechanism 3 includes a second active roller 31, a second driven roller 32 abutting against the second active roller 31, a second drive motor 33 transmission-connected to the second active roller 31, and a cutter arranged on one side of the second active roller 31; the second active roller 31 and the second driven roller 32 are used to clamp the waste belt 4 squeezed out from the material receiving mechanism 2, and the second drive motor 33 is used to drive the second active roller 31 to rotate, so that the second active roller 31 drives the second driven roller 32 to rotate at the same time, and then the waste belt 4 clamped between the second active roller 31 and the second driven roller 32 is squeezed out from the side where the cutter is located, and the cutter is used to cut the waste belt 4.

[0040] Specifically, in the present embodiment, the second active roller 31 is meshed with the second driven roller 32, and can drive the second driven roller 32 to rotate simultaneously when the second driving cylinder 33 drives the second active roller 31 to rotate. The middle parts of the second active roller 31 and the second driven roller 32 are in contact with the waste belt 4 for clamping the waste belt 4. Under the action of friction force, the waste belt 4 moves in the direction of rotation of the second active roller 31 and the second driven roller 32, and transmits the waste belt 4 to one side of the cutter.

[0041] Specifically, in this embodiment, the waste cutting mechanism 3 also includes a base plate 35, the base plate 35 is welded to the top of the circular knife machine body 1, the second active roller 31 and the second driven roller 32 are arranged in a fixed plate fixed on the base plate 35 through a rotating shaft, and the top of the second driven roller 32 is connected to a pressure regulating cylinder 34 for adjusting the degree of compression between the second active roller 31 and the second driven roller 32.

[0042] Specifically, in the present embodiment, the waste cutting mechanism 3 further comprises a cutter driving device, which comprises a cutter driving cylinder 38 for driving the cutter for cutting and an adjusting handle 39 for adjusting the cutting direction of the cutter. The cutter is divided into an upper cutter 36 and a lower cutter 37. The upper cutter 36 is connected to the cutter driving cylinder 38 by transmission. The lower cutter 37 is arranged on the circular knife machine and one side is connected to the adjusting handle 39. One end of the lower cutter 37 is rotatably arranged on a fixed plate. The cutter driving cylinder 38 and the pressure regulating cylinder 34 are arranged side by side. The waste belt 4 transmitted from the second active roller 31 and the second driven roller 32 is transmitted to the opening of the upper and lower cutters. The upper and lower cutters complete the cutting of the waste belt 4 under the transmission of the cutter driving cylinder 38.

[0043] The specific workflow of the circular knife machine can include the following operations:

[0044] The waste belt 4 remaining after the coil is cut by the circular knife machine is manually passed through the receiving mechanism 2 and the waste cutting mechanism 3. After the circular knife machine starts working, the waste belt 4 is transmitted through the friction force generated by the first active roller 21 in the receiving mechanism 2 driving the first driven roller 22 to rotate. The first drive motor 23 is connected to the first active roller 21 for transmission. The first active roller 21 is meshed with the first driven roller 22. The pressure regulating hand wheel controls the degree of compression between the first active roller 21 and the first driven roller 22. Under the action of the friction force, the waste belt 4 is tightened and transmission starts in sequence. The second active roller 31 in the waste cutting mechanism 3 is meshed with the second driven roller 22. The driven roller 32 also adopts the principle of friction to pull the waste belt 4 collected in the material receiving mechanism 2 into the waste cutting mechanism 3. The pressure regulating cylinder 34 controls the degree of compression between the second active roller 31 and the second driven roller 32 to maintain the friction between the rollers. The waste belt 4 is transported to one end of the cutter by the second active roller 31 and the second driven roller 32. The upper cutter 36 is driven by the cutting drive cylinder to move relative to the lower cutter 37, and the waste belt 4 is cut. The cut waste belt 4 falls into the recovery box 5 arranged on one side of the circular knife machine under the action of gravity. At this point, the waste cutting and collection work is completed.

[0045] The circular knife machine provided by the utility model is provided with a material receiving mechanism 2 and a waste cutting mechanism 3 on the top. The material receiving mechanism 2 collects the waste cut out by the circular knife machine and conveys it to the waste cutting mechanism for cutting. The cut waste is transferred to the recycling box 5 for collection. All waste can be collected and processed in a centralized manner, the number of servo axes is saved, the space utilization rate of the circular knife machine is improved, the downtime for changing waste is saved, and the production efficiency is improved. In addition, this scheme has a simple structure and strong practicality.
