[0038] Example

[0039] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] like Figure 1-5 As shown, a circular knife machine with an additional guide rod capable of adjusting the waste discharge direction at multiple angles comprises a circular knife machine body 1;

[0041] Sliding mechanism 2, which is fixedly connected to the outside of the circular knife machine body 1 and is used to adjust the guide position laterally;

[0042] The support rod 3 is arranged on the side of the sliding mechanism 2 away from the circular knife machine body 1;

[0043] A fixed connecting block 4 is movably connected to the surface of the support rod 3;

[0044] The guide rod body 5 is movably connected to the outer side of the fixed connection block 4 and is used to guide the waste;

[0045] Main fixing screw 6, the main fixing screw 6 is movably connected to the inner wall of the support rod 3, and the main fixing screw 6 is used to install and fix the support rod 3;

[0046] The connecting block fastening screw 7 is movably connected to the inner wall of the fixed connecting block 4, and the connecting block fastening screw 7 is movably connected to the surface of the support rod 3;

[0047] The roller changing assembly 8 is movably connected to the inner wall of the guide rod body 5 , and the roller changing assembly 8 is used to replace the guide rod body 5 .

[0048] In this embodiment, the sliding mechanism 2 includes a slide rail 201, an inner slider 202, a through screw hole 203 and a fastening screw 204. The slide rail 201 is fixedly connected to the side of the circular knife machine body 1 close to the support rod 3, the inner slider 202 is movably connected to the inner wall of the slide rail 201, the through screw hole 203 is opened on the surface of the inner slider 202, and the fastening screw 204 is movably connected to the inner wall of the through screw hole 203. The fastening screw 204 is movably connected to the slide rail 201 on the side close to the circular knife machine body 1. The main fixing screw 6 installs the support rod 3 on the inner slider 202. By sliding the inner slider 202 along the inner side of the slide rail 201, the position of the support rod 3 can be adjusted at the same time, thereby improving the flexibility of the circular knife machine body 1 during operation. When moving to the required working position, the fastening screw 204 is rotated inside the through screw hole 203, so that the fastening screw 204 penetrates the through screw hole 203 and presses against the inner side of the slide rail 201 to complete the position fixation of the inner slider 202.

[0049] In this example, the fastening screw 204 is fixedly connected to a turning handle 9 on the side away from the circular knife machine body 1, and the surface of the turning handle 9 is provided with anti-slip grooves. The inner sliding block 202 is provided with a matching screw hole 10 on the side away from the circular knife machine body 1. The inner wall of the matching screw hole 10 is movably connected to the fastening main fixing screw 6. By providing the turning handle 9, it is convenient to rotate the fastening screw 204 when no tools are used. Due to the limitation of manual rotation, it is not easy for the fastening screw 204 to cause damage to the slide rail 201 due to excessive rotation. The anti-slip grooves can prevent the hand from slipping during rotation.

[0050] In this embodiment, the roller changing assembly 8 includes an inner fixed roller 801, a ball bearing 802, an outer rotating roller 803, a roller changing screw hole 804 and a fixing screw 805. The inner fixed roller 801 is fixedly connected to the surface of the fixed connection block 4, the ball bearing 802 is movably connected to the surface of the inner fixed roller 801, the outer rotating roller 803 is movably connected to the side of the ball bearing 802 away from the inner fixed roller 801, the roller changing screw hole 804 is opened on the side of the outer rotating roller 803 away from the fixed connection block 4, the fixing screw 805 is movably connected to the inner wall of the roller changing screw hole 804, and the fixing screw 805 is movably connected to the guide rod body 5. By loosening the fixing screw 805 from the inner side of the roller changing screw hole 804 5. Then, remove the guide rod body 5 from the side of the outer side of the outer rotating roller 803 away from the fixed connecting block 4, and then replace the required guide rod body 5, and put it on the outer side of the outer rotating roller 803, screw the fixed screw 805 into the roller-changing screw hole 804, and connect and tighten the outer rotating roller 803 and the guide rod body 5 to complete the replacement of the guide rod body 5. When guiding the discharge of excess waste, the outer rotating roller 803 rotates on the outside of the inner fixed roller 801. Because the ball bearing 802 is provided to connect the inner fixed roller 801 and the outer rotating roller 803, the outer rotating roller 803 and the externally fixed guide rod body 5 can rotate smoothly and not easily get stuck.

[0051] In this example, a through hole 11 is provided on the side of the guide rod body 5 away from the fixed connecting block 4, and the inner wall of the through hole 11 is movably connected to the fixed screw 805. By setting the through hole 11 and the roller-changing screw hole 804, the fixed screw 805 passes through the through hole 11 and the roller-changing screw hole 804 for connection, making the structure more reasonable.

[0052] In this example, a limiting slot 12 is provided on the side of the outer rotating roller 803 away from the fixed connecting block 4, and a limiting plug rod 13 is fixedly connected to the inner wall of the guide rod body 5 away from the fixed connecting block 4. The surface of the limiting plug rod 13 is movably connected to the limiting slot 12. By setting the limiting slot 12 and the limiting plug rod 13, it is convenient to limit the position of the guide rod body 5 when the guide rod body 5 and the outer rotating roller 803 are connected, thereby limiting it and preventing it from rotating.

[0053] In this example, the side of the surface of the guide rod body 5 close to the fixed connecting block 4 and the side of the surface away from the fixed connecting block 4 are both fixedly connected with a limiting ring 14. By setting the limiting ring 14, the position of the removed waste can be limited on the surface of the guide rod body 5 to prevent it from falling off from one side of the guide rod body 5 and causing failure to operate normally.

[0054] In this example, the bottom of the support rod 3 is fixedly connected with an anti-slip limit plate 15. By setting the anti-slip limit plate 15, the bottom of the guide rod body 5 is limited to prevent the fixed connection block 4 from falling from the bottom of the guide rod body 5 and injuring the material or the user.

[0055] In this example, a scale groove 16 is provided on the surface of the support rod 3. By providing the scale groove 6, it is easy to observe the position of the fixed connection block 4 moving on the support rod 3, which facilitates the adjustment of the position of the fixed connection block 4.

[0056] In this example, both sides of the slide rail 201 are movably connected with a filling block 17, and the side of the filling block 17 close to the inner slider 202 is used in conjunction with the inner slider 202. By setting the filling block 17, the position of the inner slider 202 can be easily limited to prevent it from falling from the inside of the slide rail 201. Removing the filling block 17 can facilitate adding or removing the inner slider 202 to the inner side of the slide rail 201.

[0057] The guide rod 5 of the embodiment of the present invention is a circular knife machine with multi-angle adjustment of the waste discharge direction. First, the support rod 3 is installed on the inner slide 202 by the main fixing screw 6, and the inner slide 202 is slid along the inner side of the slide rail 201, so that the position of the support rod 3 can be adjusted. When it moves to the required working position, the fastening screw 204 is rotated by the turning handle 9 inside the through-screw hole 203, so that the fastening screw 204 penetrates the through-screw hole 203 and is pressed against the inner side of the slide rail 201 to complete the position fixation of the inner slide 202. The support rod 3 is installed on the sliding mechanism 2 by the main fixing screw 6. When in use, the connecting block fastening screw 7 is first rotated. When the connecting block fastening screw 7 is no longer connected to the support rod 3, the fixed connecting block 4 can be moved up and down along the support rod 3 and the fixed connecting block 4 can be rotated to adjust the position of the guide rod body 5 connected to the fixed connecting block 4. After that, tighten the connecting block fastening screw 7 so that the connecting block fastening screw 7 is pressed against the support rod 3, completing the fixation of the guide rod body 5. When the guide rod body 5 needs to be replaced according to different work types, the fixing screw 805 can be loosened from the inside of the roller-changing screw hole 804, and then the guide rod body 5 is removed from the side of the outer rotating roller 803 away from the fixed connecting block 4. Then, replace the required guide rod body 5, and sleeve it on the outer side of the outer rotating roller 803, screw the fixing screw 805 into the roller-changing screw hole 804, and fasten the outer rotating roller 803 and the guide rod body 5 to complete the replacement of the guide rod body 5. When guiding the discharge of excess waste, the outer rotating roller 803 rotates on the outside of the inner fixed roller 801. Because the ball bearing 802 is provided to connect the inner fixed roller 801 and the outer rotating roller 803, the outer rotating roller 803 and the externally fixed guide rod body 5 rotate smoothly.

[0058] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
