[0002] The film guiding roller of the finished paper wrapping machine is an important part of the packaging machinery. It rolls and guides the packaging film to ensure that the film can be accurately and evenly covered on the items to be packaged, thereby achieving efficient and high-quality packaging operations.
[0003] However, the film guiding roller of the original finished paper wrapping machine is made of thin iron sheet. Because the roller is relatively slender, the bearing used is a thin-walled needle bearing with limited load-bearing capacity. The roller body and the bearing are easily damaged, so the service life is short and failures occur frequently. In addition, the outer ring of the bearing is installed and fixed at the riveted and welded structure connected to the roller body. The welding points are easy to fall off, and the bearing is very easy to fall apart. The inner ring of the bearing is fixed at only two flanges on both sides of the outer edge of the shaft, which are symmetrical and can hardly be repaired after wear.
[0004] Therefore, it is urgent to improve the film guiding roller of the finished paper wrapping machine to solve the above-mentioned problems. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a film guiding roller of a finished paper wrapping machine, including a stepped shaft and a roller, both ends of the stepped shaft are provided with step grooves, the interior of the roller is provided with a second step groove, both ends of the stepped shaft are provided with bearings, one side of the bearing is against the step groove and the second step groove, the step groove and the second step groove are respectively provided with a first annular groove and a second annular groove, and a limit baffle for limiting the bearing is movably installed through the first annular groove and the second annular groove.
[0007] Preferably, the bearing is a deep groove ball bearing, and the roller is an aluminum alloy roller.
[0008] Preferably, the first annular groove and the second annular groove correspond in position, and a rubber layer is attached to both the first annular groove and the second annular groove.
[0009] Preferably, the upper and lower sides of the limit baffle are symmetrically provided with mounting mechanisms for mounting the limit baffle, and the mounting mechanism includes a slide groove opened on the limit baffle, a first limit mechanism slidably connected to the upper part of the slide groove, and a second limit mechanism slidably connected to the lower part of the slide groove.
[0010] Preferably, a partition is provided in the middle part of the slide groove, and the first limiting mechanism includes a first compression spring connected to the lower end of the partition, a lever connected to the lower end of the first compression spring, a first sliding rod sliding with the limiting baffle and connected to the lower end of the lever, and a sliding block connected to the lower end of the first sliding rod and slidably connected to the first annular groove.
[0011] Preferably, the second limiting mechanism includes a second compression spring connected to the upper end of the partition, a second lever connected to the upper end of the second compression spring, a second sliding rod slidably connected to the limiting baffle and connected to the upper end of the second lever, and a second sliding block connected to the upper end of the second sliding rod and slidably connected to the second annular groove.

Because the drum is installed vertically, in order to reduce the weight of the drum itself and reduce the load on the bearing, the drum body adopts an aluminum alloy drum to maximize the service life of the bearing. At the same time, deep groove ball bearings have a longer service life than traditional thin-walled needle roller bearings. At the same time, by utilizing the step groove, the second step groove, the first annular groove, the second annular groove and the setting of the limit baffle, the bearing can be quickly replaced, so that the film-guiding drum can extend the service life and reduce the maintenance cost, which provides strong technical support for the optimization of mechanical equipment, reducing the occurrence of failures and saving maintenance time. Moreover, after long-term use, it is easy to replace the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] like Figure 1-Figure 6 As shown, the film guiding roller of the finished paper film wrapping machine provided in this embodiment comprises a stepped shaft 1 and a roller 2, both ends of the stepped shaft 1 are provided with a stepped groove 3, the interior of the roller 2 is provided with a second stepped groove 4, both ends of the stepped shaft 1 are provided with bearings 5, the bearings 5 are deep groove ball bearings, the roller 2 is an aluminum alloy roller, and the deep groove ball bearings have a longer service life than the traditional thin-walled needle bearings. Because the roller 2 is installed vertically, in order to reduce the weight of the roller 2 itself and reduce the load of the bearing 5, the main body of the roller 2 is an aluminum alloy roller, which maximizes the service life of the bearing 5; both ends of the stepped shaft 1 are provided with roller fixing threaded holes 23 for installing the film guiding roller;
[0026] like Figure 4As shown, one side of the bearing 5 abuts against the step groove 3 and the second step groove 4, and the step groove 3 and the second step groove 4 are respectively provided with a first annular groove 6 and a second annular groove 7, and a limiting baffle 8 for limiting the bearing 5 is movably installed through the first annular groove 6 and the second annular groove 7;
[0027] Among them Figure 4 As shown, the upper and lower sides of the limit baffle 8 are symmetrically provided with mounting mechanisms for mounting the limit baffle 8, and the mounting mechanisms include a slide groove 9 opened on the limit baffle 8, a first limit mechanism 10 slidably connected to the upper part of the slide groove 9, and a second limit mechanism 11 slidably connected to the lower part of the slide groove 9;
[0028] Further, such as Figure 4 and Figure 6 As shown, a partition 12 is provided in the middle part of the slide groove 9, and the first limiting mechanism 10 includes a first compression spring 13 connected to the lower end of the partition 12, a lever 14 connected to the lower end of the first compression spring 13, a first slide bar 15 sliding with the limiting baffle 8 and connected to the lower end of the lever 14, and a slider 16 connected to the lower end of the first slide bar 15 and slidably connected to the first annular groove 6;
[0029] Furthermore, the second limiting mechanism 11 includes a second compression spring 17 connected to the upper end of the partition 12, a second lever 18 connected to the upper end of the second compression spring 17, a second slide bar 19 connected to the limiting baffle 8 in a sliding manner and connected to the upper end of the second lever 18, and a second slider 20 connected to the upper end of the second slider 19 and connected to the second annular groove 7 in a sliding manner. When the bearing 5 needs to be replaced, the limiting baffle 8 is disassembled and the bearing 5 is taken out by operating the installation mechanisms on the upper and lower sides of the limiting baffle 8 at the same time. When operating the installation mechanism, the lever 14 and the second lever 18 are pressed inward at the same time to make the first compression spring 13 and the second compression spring 17 are simultaneously contracted inwardly, so that the slider 16 and the second slider 20 are respectively disengaged from the first annular groove 6 and the second annular groove 7, and then pulled outwardly, so that the limit baffle 8 can be quickly taken out from the inside of the drum 2, thereby realizing the removal of the bearing 5. After the replacement is completed, the bearing 5 is sleeved on the stepped shaft 1 until it abuts against the step groove 3 and the second step groove 7, and then the limit baffle 8 is engaged in the first annular groove 6 and the second annular groove 7 by the installation mechanism, so as to realize the fixing of the bearing 5 after replacement. It should be noted that the bearings 5 at both ends are replaced in sequence, not at the same time.
[0030] Going further, Figure 4-Figure 5As shown, the positions of the first annular groove 6 and the second annular groove 7 correspond, and a rubber layer is attached to the first annular groove 6 and the second annular groove 7. The side of the slider 16 close to the first annular groove 6 and the side of the second slider 20 close to the second annular groove 7 are rotatably connected with a plurality of steel balls 21 in contact with the rubber layer on the annular groove. The setting of the steel balls 21 will not affect the rotation of the drum 2. At the same time, the contact with the rubber layer can greatly reduce the wear rate of the steel balls 21 and improve the quietness. A hidden groove 22 for hiding the slider 16 and the second slider 20 is provided on the limit baffle 8. The hidden groove 22 can be completely hidden in the hidden groove 22 when the slider 16 and the second slider 20 are recovered later, so as to facilitate the removal of the limit baffle 8 later.
