AI Technical Summary
When the ZL29 forming machine is running, poor opening of the filament bundles occurs, resulting in white spots on the end face of the filter rods and curling of the filament bundles. The main reason is that the design of the opening roller swing arm is unreasonable, which leads to high sliding friction resistance between the roller seat and the copper sleeve, and the cylinder cannot drive it.
A through hole and bearing are provided at the top of the opening roller swing arm, and a combination of slot and elastic clamping component is used to reinforce it to ensure that the bearing and the roller seat area have sufficient contact and fixing area, thereby improving the assembly stability and easy disassembly.
By combining a bearing-type design with an elastic clamping assembly, the operational stability of the opening roller and the robustness of the bearing are significantly improved, solving the problem of poor yarn opening and ensuring the reliability and long-term operational stability of the equipment.

[0002] In cigarette production process, ZL29 former appears tow opening bad phenomenon when running, causing filter rod end face to have white spot, tear opening forming paper and find that tow exists obvious curling. It is found that it is because swing bar in opening roll moving part is stuck. Analyze for this fault phenomenon, find that the unreasonable design of ZL29 former opening roll swing bar is main reason, opening roll is pressed to the process in screw roll, swing bar and copper sleeve, roll seat and copper sleeve are all sliding friction, due to the reason of bearing, roll seat and copper sleeve wear are all more serious, friction resistance is particularly obvious, cylinder cannot overcome friction resistance to drive opening roll. For the main resistance source of roll seat and copper sleeve, the solution is to change the sliding friction of roll seat and copper sleeve into the rolling friction of bearing. But because the space in opening roll is narrow, the above-mentioned improvement must use thin-wall bearing, to ensure that the outer wall diameter of thin-wall bearing after assembly is same with the outer wall diameter of original copper sleeve;At the same time, because swing bar is a standard part, when improving original swing bar, it must be ensured that the total length of thin-wall bearing after being assembled on swing bar is equal to the length of swing bar before improvement;At the same time, the depth of roll seat area is small, so, in this narrow space, it is also necessary to ensure that the top of assembled thin-wall bearing is flush with the top of swing bar, to ensure that thin-wall bearing and roll seat area have enough contact fixing area, to guarantee assembly reliability, but at this time, it is necessary to solve the problem of firmness of thin-wall bearing after assembly.

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0019] In the description of the utility model, it needs to explain, the term "in", "before", "after", "left", "right" and so on indicate the position relation or location relation is based on the position relation or location relation shown in the drawing, or is the position or location relation of the utility model product when using the usual place, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as a limitation on the utility model.
[0020] In the description of the utility model, it also needs to explain that, unless otherwise expressly provided and limited, the terms "set", "connect" should be understood broadly, for example, it can be fixedly connected, can be detachably connected, or integrally connected, can be mechanically connected, can be electrically connected, can be directly connected, can be indirectly connected through an intermediate medium, and can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0021] As shown in Figures 1 to 4 A kind of open roller bearing type swing bar, the top of swing bar 1 is provided with through hole and hole channel 104, including first through hole 105 and second through hole 106 in the embodiment;Also include bearing 2 (bearing 2 includes outer ring 201, inner ring 202, retainer 203 and rolling body 204), in the embodiment, considering the limited wall thickness of swing bar 1, the bearing 2 is preferably thin-walled bearing;The swing bar 1 includes base 101, the upper portion of the base 101 is provided with step 102, the step 102 extends to the top of the base 101, and in turn forms shoulder 103 on the top of base 101, the bearing 2 is sleeved on the step 102;Preferably, the height of the shoulder 103 is equal to the thickness of the bearing 2. The purpose of such design is: considering the limited contact fixing area of bearing and roller seat area, the contact point starts from the top of shoulder 103, so the top of bearing 2 and the top of shoulder 103 are set flush, to ensure the stability after assembly.
[0022] Because the pendulum rod 1 before improvement belongs to a standard part, the size space that can be modified is very limited, resulting in that when the standard part is modified, the thickness of the bearing 2 that can be used is smaller (such as the optional thin-walled bearing thickness is about 5 mm or less), and the bearing 2 is arranged at the top end (that is, the bearing 2 is to correspond to the copper sleeve in the standard part, so when assembling, the copper sleeve part in the original standard part needs to be removed, and then the bearing 2 is replaced, and the thickness and wall thickness of the bearing 2 are matched with the original copper sleeve part); in the high-speed operation of the equipment, axial force will appear, therefore, in order to further improve the firmness of the combination of the bearing 2 and the pendulum rod 1, in addition to interference fit, the embodiment is further assisted to be provided with the following scheme: corresponding to the first through hole 105 and the second through hole 106, a clamping groove 6 is arranged, and the outer side of the clamping groove 6 communicates with the step 102; the elastic compression assembly is detachably arranged in the clamping groove 6, that is, one side of the bearing 2 is extruded by the elastic compression assembly, and the anti-vibration and anti-loose performance of the bearing 2 is assisted to be improved. As shown in Figure 2 , the first through hole 105 and the second through hole 106 are arranged on the same side of the pendulum rod 1.
[0023] Optionally, as shown in Figure 4 , the elastic compression assembly comprises an elastic member body 3, and the elastic member body 3 is an annular member provided with a notch 4. The elastic compression assembly further comprises a compression member 5, and the compression member 5 is an arc-shaped body and its front view is a fan shape. The notch 4 is arranged in a manner that the upper part is wide and the lower part is narrow, and the height h1 of the compression member 5 is less than the height h2 of the elastic member body. The beneficial effect of such design is that after the bearing 2 is assembled into the step 102, the elastic member body 3 is assembled into the clamping groove 6, and the notch 4 is inward, that is, the non-notch area of the elastic member body 3 is against the bearing 2 on the outside, then the compression member 5 is knocked into the notch 4, and as the compression member 5 is knocked in, the elastic member body 3 is stretched and stretched, thereby promoting the elastic member body 3 in the two clamping grooves 6 to extrude the bearing 2, which can reduce the size expansion and vibration due to temperature difference during operation, and significantly improve the firmness of the combination of the bearing 2 and the stability of the equipment operation.
