[0005] The purpose of the utility model can be realized by the following technical solutions:

[0026] Embodiment 1

[0027] Please refer to Figures 1 to 3 , which is a schematic diagram of a tape paper tube conveying push tube mechanism provided by the present utility model. The tape paper tube conveying push tube mechanism includes: a frame 10, a feeding platform 40 and a conveying component 20 arranged on the frame 10, and a push tube component 30 arranged on one side of the conveying component 20. It can be imagined that the tape paper tube conveying push tube mechanism further includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, which are all well-known technologies to those skilled in the art, so they will not be described in detail one by one here

[0028] The frame 10 serves as the main installation bracket of the equipment, provides a carrier for the assembly of multiple component assemblies, and at the same time provides a good flat ground environment

[0029] The conveying assembly 20 includes two conveying frames 21 that are spaced apart and arranged on the frame 10. The two conveying frames 21 are fixedly connected to each other, having high structural strength to prevent structural deviation of the two conveying frames 21. A conveyor belt 22 is provided on the conveying frame 21. The conveyor belt 22 is wound around the rotating rollers at both ends of the conveying frame 21 to form a cyclic conveyance. The rotating rollers on the two conveying frames 21 are connected to the same conveying driver 24 for driving the conveyor belt 22 and maintaining synchronous driving on the two conveying frames 21. Paper tube clamps 23 are spaced apart on the conveyor belt 22 and arranged along the length direction of the conveyor belt 22. The paper tube clamps 23 serve as fixed fulcrums for the adhesive tape paper tubes on the conveyor belt 22, and at the same time reduce the contact area between the adhesive tape paper tubes and the conveying assembly 20, making it easier for the adhesive tape paper tubes to maintain a horizontal placement posture, which is conducive to being later pushed onto the positioning structure of the pipe cutting machine. In this embodiment, the positioning structure of the pipe cutting machine is a positioning post inserted into the inner side of the adhesive tape paper tube. The outer circle of the positioning post has elasticity and extrusion deformation performance, and the positioning post is kept in contact with the inner wall of the adhesive tape paper tube. It can be imagined that the distance between the two conveying frames 21 is greater than the minimum length of the adhesive tape paper tube, ensuring the positioning structure of the adhesive tape paper tube on the conveying assembly 20, and there is always a pipe pushing fulcrum during the pipe pushing process, reducing the pipe pushing resistance and improving the accuracy of pipe pushing. A limiting universal card slot 25 that is recessed downward and arranged along the width direction of the conveyor belt 22 is provided on the paper tube clamp 23. In this embodiment, the limiting universal card slot 25 is positioned by the outer wall of the adhesive tape paper tube, and the limiting universal card slot 25 can be applied to adhesive tape paper tubes of multiple sizes. Specifically, the outer wall contour of the adhesive tape paper tube is circular, the cross-section of the limiting universal card slot 25 is U-shaped, and the inner walls of the two bottom sides of the limiting universal card slot 25 are provided with tapered surfaces 26 whose inner diameters gradually decrease from top to bottom. The maximum outer diameter of the adhesive tape paper tube is smaller than the maximum outer diameter of the limiting universal card slot 25. The adhesive tape paper tube can be clamped into the limiting universal card slot 25, and the two bottom sides of the adhesive tape paper tube are in contact with the tapered surfaces 26. The paper tube clamp 23 is provided with a guiding inclined surface 27 at the opening end of the limiting universal card slot 25. The guiding inclined surface 27 is used for the adhesive tape paper tube to enter the limiting universal card slot 25 faster and more accurately.

[0030] Please refer to Figure 5 , the pre-processing structure of the conveying assembly 20 is a loading platform 40. The loading platform 40 is arranged at the loading end of the machine near the conveying assembly 20. A through material dropping port 41 is provided on the loading platform 40. One end of the conveying frame 21 is located below the material dropping port 41. The paper tube clamp 23 can rotate through the lower end of the material dropping port 41. It can be imagined that the inner diameter of the material dropping port 41 is smaller than the maximum inner diameter of the limiting universal card slot 25. The upper end of the paper tube clamp 23 approaches the lower end edge of the material dropping port 41. The mass of the adhesive tape paper tube is relatively heavy to ensure the falling speed of free fall. The distance between the two paper tube clamps 23 is smaller than the minimum outer diameter of the adhesive tape paper tube to avoid the problem of material jamming when the adhesive tape paper tube falls into the gap between the paper tube clamps 23.

[0031] Please refer to Figure 2 Figure 2 , the pusher tube assembly 30 includes a guide frame 31 disposed on one side of the rack 10 and located at one side of the conveying frame 21. The guide frame 31 is a frame structure disposed on one side of the conveying frame 21. A guide post structure is disposed on the frame structure along the width direction of the conveying frame 21. A push plate 32 that moves along the width direction of the conveying frame 21 is slidably connected to the guide frame 31. The guide frame 31 provides a reliable bottom support for the sliding of the push plate 32, and has stability and precise sliding guidance during the pushing force application process. A pusher tube driver 34 is connected to the push plate 32, which is used to provide the power for driving the push plate 32 to slide along the guide frame 31. In this embodiment, the pusher tube driver 34 is a cylinder.

[0032] Pusher tubes 33 are spaced apart at one end of the push plate 32 close to the conveying frame 21. Each pusher tube 33 is used to correspondingly abut against the end of a single adhesive tape paper tube, and horizontally axially push the adhesive tape paper tube to disengage from the paper tube clamp 23 and enter the positioning structure of the tube cutting machine.

[0033] Please refer to Figure 4 Figure 4 , optimally, a pusher tube head 35 is slidably sleeved on the pusher tube 33. The pusher tube head 35 and the pusher tube 33 are elastically connected by a spring 36. The elastic potential energy of the spring 36 forces the pusher tube head 35 to move towards the outer end of the pusher tube 33. A limiting shoulder 37 that restricts the pusher tube head 35 from detaching from the pusher tube 33 is provided at one end of the pusher tube 33 away from the push plate 32. That is, without external force, one end of the pusher tube head 35 abuts against the limiting shoulder 37. The inner diameter of the adhesive tape paper tube is greater than the outer diameter of the limiting shoulder 37, and the inner diameter of the adhesive tape paper tube is less than the outer diameter of the pusher tube head 35, ensuring that the pusher tube head 35 is in contact with the end of the adhesive tape paper tube. The elastic action of the spring 36 can ensure that the adhesive tape paper tube is abutted in place while ensuring that the axial force on the adhesive tape paper tube is not damaged.

[0034] The end face of the end of the pusher tube head 35 away from the pusher tube 33 protrudes from the end face of the limiting shoulder 37. This structure ensures that the pusher tube head 35 pre-contacts the end of the adhesive tape paper tube, and can enable the offset adhesive tape paper tube to re-enter the accurate positioning state under pushing.

[0035] A recessed annular step 38 is provided at the edge of the end of the pusher tube head 35 away from the pusher tube 33. The annular step 38 is used for positioning the adhesive tape paper tube with a large inner diameter, and has high accuracy during the pushing process.
