Description

Technical Field

[0001] The utility model relates to the field of paper product processing parts and components, in particular to a front edge paper feeding wheel which is not easy to jump off. Background Art

[0002] With the progress of industrialization, automated production machinery has been born in various industries, and paper processing machinery is no exception.

[0003] At present, paper processing machines are generally provided with a paper feeding wheel to realize compaction and conveying of paperboards. In order to obtain ideal working performance, the existing paper feeding wheels are either made of an integrated colloid material or made of a composite of a colloid material and a metal wheel. The glue layer of the existing paper feeding wheels that contacts the paperboard cannot be disassembled, so that when local wear or aging and breakage occur, the entire paper feeding wheel (the glue layer part) can only be replaced, which affects production operations and increases the cost of use. At the same time, the bearing wheel frames that cooperate with the rotating shaft rollers are all fixed structures and cannot be disassembled. When in use, if one of them is worn or broken, it will affect the paper feeding effect of the entire paper feeding wheel;

[0004] For the improvement of the current technology, patent No. 2023204995704 discloses a front-edge paper feed wheel that is not easy to jump off, including a wheel body, mounting grooves are provided on both sides of the mounting end of the wheel body, and limiting grooves that do not penetrate to the outside are provided on both sides of the inner wall of the mounting groove, and a mounting component is slidably connected in the mounting groove, and the mounting component includes a mounting block, a slider matching the mounting groove is fixed on the upper end of the mounting block, and one end of the slider extends to the outside of the mounting block, and a limiting block matching the limiting groove is fixed on one end of the slider located on the outside of the mounting block. This paper feed wheel is designed to be detachable and easy to assemble;

[0005] However, the above scheme has a defect, that is, the front edge paper feeding wheel at the position of the installation component is disconnected. At the moment of starting, the paper feeding wheel rotates at a relatively high speed, so the front edge paper feeding wheel will have a large centrifugal force, which will cause the installation component at this position to jump out of the groove of the metal wheel and separate from the metal wheel, so that it cannot be used, affecting production;

[0006] Therefore, in view of the technical problems described above, there is an urgent need for a leading edge paper feeding wheel that is not easy to jump off. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a front edge paper feeding wheel which is not easy to jump off.

[0008] In order to solve the above technical problems, the technical solution provided by the utility model is a front edge paper feeding wheel that is not easy to jump off, comprising:

[0009] Ring;

[0010] A circular ring is provided in the middle of the inner wall of the collar, and a plurality of connecting cylinders are evenly provided on the inner wall of the collar, one of the connecting cylinders is provided with an opening penetrating the connecting cylinder, the collar and the circular ring, the opening disconnects the collar, the circular ring and one of the connecting cylinders, a docking groove is provided on the inner wall on one side of the opening, and a docking connection part is provided on the inner wall on the other side of the opening, the docking connection part cooperates with the docking groove, and when the two ends of the collar are docked together, they are used to connect and fix the two ends of the collar to form a whole.

[0011] As an improvement, the docking connection portion and the docking slot are both located on the connecting cylinder.

[0012] As an improvement, the connecting cylinder passes through the ring.

[0013] As an improvement, a ring protrudes from the inner side of the connecting cylinder.

[0014] Compared with the prior art, the utility model has the following advantages: 1. An opening penetrating the connecting cylinder, the collar and the ring is provided on one of the connecting cylinders, and the opening disconnects the collar, the ring and one of the connecting cylinders, so that it is convenient to install the front edge paper feeding wheel on the metal wheel;

[0015] 2. A docking slot is provided on the inner wall on one side of the opening, and a docking connection part is provided on the inner wall on the other side of the opening. The docking connection part cooperates with the docking slot. When the two ends of the collar are docked together, the two ends of the collar are connected to form a whole. Since the docking connection part is stuck in the docking slot, it plays a role of fixing the two ends of the collar. In this way, when the front edge paper feeding wheel starts to rotate, the connecting cylinder at the opening will not jump out of the metal wheel mounting groove. On the one hand, production is guaranteed, and on the other hand, it is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
