Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to a rolling auxiliary tool for adjusting the floating ring of a cigarette making machine. Background Art

[0002] Cigarette making machines (such as the YJ118 model) are designed with floating ring devices on the cigarette cutting drum and the filter cigarette cutting drum. The function of the floating ring device is that as the cigarette rotates with the cutting drum, the two floating rings gradually push the double-length cigarette to the middle position of the cutter, ensuring that the cutter cuts at the midpoint of the double-length cigarette.

[0003] The working principle of the floating ring is as follows: the floating ring is connected to the fixed ring through a tension spring, the fixed ring is fixed on the drum wheel, the roller arm and the small roller force the two floating rings to form a certain angle, and the distance between the narrowest parts of the two floating rings can be adjusted by rotating the adjusting rod.

[0004] During the production process, the small roller is made of cast iron. As it wears, its diameter will shrink, causing the distance between the two float rings at the narrowest point to be greater than twice the length of the cigarette. As a result, the cut cigarettes will be of different lengths, resulting in product quality defects. In addition, because the small roller of the inner float ring cannot be observed and adjusted at any time, and the replacement process is complicated, there is an urgent need for a solution for adjusting the float ring of a cigarette making machine. Utility Model Content

[0005] In view of the above, the utility model aims to provide a rolling auxiliary tool for adjusting the float ring of a cigarette making machine to solve the above-mentioned technical problems.

[0006] The technical solution adopted by the utility model is as follows:

[0007] The utility model provides a rolling auxiliary tool for adjusting the floating ring of a cigarette making machine, which comprises: a bearing made of eutectoid steel, a bearing bracket, a slotted cylindrical screw and a connecting shaft;

[0009] One end of the bearing bracket away from the bearing is connected to a floating ring adjustment device.

[0010] In at least one possible implementation, the bearing is a deep groove ball bearing.

[0011] In at least one possible implementation manner, an isolation platform is formed on the connecting shaft for spacing the bearing and the bearing bracket.

[0012] In at least one possible implementation manner, a thickness of the bearing support is smaller than an outer diameter of the bearing.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings, in which:

[0017] Figure 1 A schematic diagram of a rolling auxiliary tool for adjusting the float ring of a cigarette making machine provided by an embodiment of the utility model. DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0019] The utility model provides an embodiment of a rolling auxiliary tool for adjusting the floating ring of a cigarette making machine. Specifically, Figure 1As shown, it includes: a bearing 1, a bearing bracket 2, a slotted cylindrical screw 3 and a connecting shaft 4, the longitudinal section of the bearing bracket 2 has a trapezoidal structure, the connecting shaft 4 passes through the relatively small end of the bearing bracket 2 in structure, one end of the connecting shaft 4 is provided with an external thread and is fixed by a nut, and the other end of the connecting shaft 4 is connected to the slotted cylindrical screw 3 for installing the bearing 1; the end of the bearing bracket 2 away from the bearing 1 (such as the relatively large end of the gun handle-shaped bracket in the figure) is connected to the original floating ring adjustment device of the cigarette making machine.

[0020] According to the preliminary analysis, the friction force of the roller is relatively large during the process of squeezing the floating ring. In order to reduce the friction, the utility model adopts a rolling friction mechanism, specifically, it is proposed to realize it with a bearing. This is mainly because the carbon content of bearing steel is generally between 0.95% and 1.15%, which belongs to eutectoid steel. The main components include carbon, silicon, manganese, chromium, molybdenum and other elements, among which chromium and molybdenum can improve the wear resistance of steel. Therefore, bearings are selected to replace rollers and in actual applications, deep groove ball bearings, such as 16001 (outer diameter 28mm, inner diameter 12mm, thickness 7mm) can be preferably used according to factors such as outer diameter size and thickness.

[0021] According to the inner diameter of the bearing 1 and the predetermined distance between the working position of the bearing and the adjustment device, the corresponding bearing bracket 2 and connecting shaft 4 are designed. Figure 1 It can be seen that the relatively thicker end of the connecting shaft 4 has a diameter of 12 mm, and a 6 mm threaded hole is provided therein for installing an M6 slotted cylindrical screw 3, and the slotted cylindrical screw 3 is used to assemble the bearing 1. Preferably, in order to avoid friction between the bearing 1 and the bearing bracket 2, the connecting shaft 4 can be formed with a 13 mm isolation platform (that is, the bearing is isolated from the bearing bracket), thereby ensuring that the rolling friction of the bearing is minimized.

[0022] An external thread is provided at the other end of the connecting shaft 4 so as to be fixed with a nut. In addition, it can be added that the thickness of the bearing bracket 2 can be designed to be much smaller than the outer diameter of the bearing 1, for example, the thickness is 15 mm, so as to effectively prevent the floating ring from interfering with or colliding with the bearing bracket during movements such as contraction and expansion.

[0023] Finally, it should be pointed out that a screw hole 5 and a pin hole 6 are provided at the other end of the bearing bracket 2, and the screw hole 5 and the pin hole 6 cooperate to position and fix the bearing bracket 2 on the floating ring adjustment device. Figure 1 As shown, the screw hole 5 and the pin hole 6 are arranged in a row at one end of the bearing bracket 2 away from the bearing 1 , and the pin hole 6 is arranged between two of the screw holes 5 .

[0024] In summary, the main design concept of the utility model is that it is specifically composed of a bearing, a bearing bracket, a connecting shaft and a slotted cylindrical screw. In order to improve the wear resistance of the roller, the roller is replaced by a bearing and connected to the bearing bracket through a connecting shaft and a slotted cylindrical screw, and the bracket is installed on the float ring adjustment device. During processing, the structural shape and preset specifications of the longitudinal section of the bearing bracket can avoid the movement trajectory of the float ring and will not affect the normal operation of the equipment. Furthermore, the use of the slotted cylindrical screw combined with the isolation table ensures that the bearing reaches the state of minimum friction. The utility model can maximize the life of the roller, ensure the accurate positioning of the float ring, and effectively avoid product quality problems caused by the position of the float ring due to the different lengths of cigarettes. At the same time, it also reduces the frequency of maintenance and adjustment and improves equipment productivity.
