Detailed Implementation

[0024] Example 1

[0025] Please see Figures 1 to 2 This is a schematic diagram of a clamping and rotating mechanism provided by this utility model. The clamping and rotating mechanism includes: a frame 10, a horizontal sliding device 710 mounted on the frame 10, a vertical lifting device 720 mounted on the horizontal sliding device 710, and a clamping and rotating device 730 mounted on the vertical lifting device 720. It is conceivable that this clamping and rotating mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and mounting structures, all of which are well-known to those skilled in the art and will not be described in detail here.

[0026] It should be noted that this clamping and rotating mechanism is suitable for cutting tubular structures, especially round tubes such as paper tubes or plastic tubes that undergo elastic deformation after being subjected to force on their outer wall. In this embodiment, a paper tube will be used as an example for detailed explanation.

[0027] The frame 10 has a rectangular frame structure, serving as a carrier for all components and facilitating assembly. In this embodiment, the length direction of the frame 10 is defined as the paper tube conveying direction.

[0028] The horizontal sliding device 710 is slidably disposed at the upper end of the frame 10 along the length of the frame 10. Specifically, the horizontal sliding device 710 includes sliding guide structures 711 disposed on both sides of the frame 10, sliding frames 712 slidably disposed at both ends on the sliding guide structures 711, and a sliding motor for driving the sliding frames 712. The sliding guide structure 711 is a horizontal guide post. The sliding motor drives the sliding frames 712 horizontally along the sliding guide structure 711, thereby adjusting the horizontal position of the clamping rotating device 730. The sliding motor can cooperate with the cable chain to achieve precise displacement of the sliding frames 712.

[0029] The vertical lifting device 720 is vertically lifted and lowered on the horizontal sliding device 710. Specifically, the vertical lifting device 720 includes a lifting cylinder 721 mounted on the sliding frame 712, and a clamping and rotating device 730 with the output end of the lifting cylinder 721. A lifting guide column structure 722 is provided between the clamping and rotating device 730 and the lifting cylinder 721. The vertical position of the clamping and rotating device 730 is adjusted by the direct drive of the lifting cylinder 721 to clamp and rotate the device 730, and the displacement is controlled and guided by the lifting guide column structure 722. It is conceivable that a limit block can be set on the lifting guide column structure 722 to adjust the vertical displacement stroke.

[0030] The clamping and rotating device 730 includes an intermediate mounting plate 731 disposed at the output end of the vertical lifting device 720. Top auxiliary rollers 734 are hinged at intervals at the bottom of the intermediate mounting plate 731. The top auxiliary rollers 734 are used to adhere to the upper surface of the paper tube. Lateral mounting plates 732 are respectively disposed on both sides of the intermediate mounting plate 731, slidingly disposed along the width direction of the frame 10. The lateral mounting plates 732 are slidably connected to the intermediate mounting plate 731 via guide rails. A transverse driver 733 is disposed on the intermediate mounting plate 731, each transverse driver 733 driving the lateral mounting plates 732 and the two lateral mounting plates 732... The displacement directions of the mounting plates 732 are opposite. Side auxiliary rollers 735, which are respectively hinged to the two side mounting plates 732 and are corresponding to the top auxiliary roller 734, are respectively connected to them. The set height of the side auxiliary rollers is lower than the set height of the top auxiliary roller. The side auxiliary rollers 735 are used to fit and support the bottom of the paper tube. The opening and clamping of the two side auxiliary rollers 735 are realized through the side mounting plates 732. Together with the top auxiliary roller 734, a three-point clamping cavity 736 is formed on the outer wall of the paper tube, which can form the clamping and positioning of the paper tube, or adopt the fitting and positioning method to increase the clamping fulcrum on the paper tube and realize auxiliary rotation.

[0031] The lateral auxiliary rollers 735 of the two lateral mounting plates 732 are axially arranged in opposite directions and face the middle mounting plate 731, so that the lateral auxiliary rollers 735 are clamped in the same area of ​​the outer circumferential wall of the paper tube, the force is uniform, and the clamping stability is increased. The top auxiliary roller 734 has two symmetrically arranged auxiliary sub-rollers, which face one side of the lateral mounting plate 732 respectively, increasing the contact area of ​​the top auxiliary roller 734 with the upper end of the paper tube and further improving the clamping reliability.

[0032] The lateral adjustment plate 743 has spaced-apart strip-shaped holes 740 arranged along the width direction of the frame 10, and stroke limiting posts 741 fixedly connected to the intermediate mounting plate 731 and passing through the strip-shaped holes 740. By forming the limiting posts in the initial position of the strip-shaped holes 740, the initial distance between the two lateral auxiliary rollers 735 can be finely adjusted, and the drive stroke of the transverse drive 733 can also be adjusted.

[0033] The lateral mounting plate 732 is provided with a sliding groove 742. A sliding adjustment plate 743 is detachably connected to the sliding groove 742 via a slot-type insertion method. By cooperating with the sliding groove 742, the initial distance between the two lateral auxiliary rollers 735 can be coarsely adjusted, or the adjustment plate 743 and the lateral auxiliary rollers 735 can be directly replaced to select an adjustment plate 743 with a suitable height difference. Optimally, the adjustment plate 743 has an L-shaped cross-section, and the lateral auxiliary rollers 735 are positioned on the side of the adjustment plate 743 near the top auxiliary roller 734. This structure allows for greater space in the three-point clamping cavity 736 and avoids contact and stress between the paper tube and the adjustment plate 743.
