Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making equipment, in particular to a cigarette making machine cloth belt guide wheel support shaft assembly. Background Art

[0002] The cloth belt guide wheel is the driving wheel that drives the cloth belt to run, and the linear speed of the cloth belt is determined by it. The linear speed of the pulley is related to its own diameter. Since there is a slight slip on the cigarette paper, the cloth belt also slips slightly on the cloth belt guide wheel, and there is also an error in the manufacturing of the diameter of the cloth belt guide wheel, so the cloth belt guide wheel is made into an expansion cloth belt guide wheel with adjustable diameter. The function of the cloth belt is to feed the tobacco strips of the cigarette paper into the cigarette gun and participate in the rolling of the tobacco strips into shape. The rubber ring is tightly sleeved on the outer ring of the cloth belt guide wheel. When the cloth belt guide wheel rotates, the friction of the rubber ring drives the cloth belt to rotate. In order to synchronize the speed of the tobacco strip with the speed of the cigarette gun cloth belt, the diameter of the cloth belt guide wheel can be adjusted by turning the nut; the relative position of the cloth belt and the cigarette gun can be adjusted by adjusting the knob; the tensioning wheel is operated by the cylinder to keep the cloth belt in a constant tension state. Due to the rolling friction between the cloth belt and the cloth belt guide wheel, the cloth belt guide wheel generates high temperature, which can easily cause the guide wheel bearing to sinter and damage, thereby causing the cloth belt guide wheel to be damaged due to uneven force. The guide wheel bearing needs to be replaced frequently after being used for a period of time.

[0003] However, before replacing the guide wheel bearing, the parts that need to be disassembled include the front workbench of the cigarette gun and the cigarette paper wheel protective cover. These two parts have many screws during the disassembly process, and disassembly and installation are more troublesome. In addition, the cigarette paper wheel protective cover is heavy, and it requires two repairmen to cooperate to complete the operation. Disassembly and installation are time-consuming and labor-intensive. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a cigarette making machine cloth belt guide wheel support shaft assembly, including a guide wheel base 100 and a guide wheel shaft 200. Among them, a connecting part 110 is provided at one end of the guide wheel base 100, and a connecting hole 111 is opened in the connecting part 110. A mounting hole 120 is opened at the other end of the guide wheel base 100. A threaded hole 130 is opened in the guide wheel base 100. The threaded hole 130 is communicated with the mounting hole 120 and is coaxially arranged. The diameter of the threaded hole 130 is smaller than the diameter of the mounting hole 120; a through hole 210 is opened along the axis of the guide wheel shaft 200, and the through hole 210 is coaxially arranged with the threaded hole 130. One end of the guide wheel shaft 200 extends into the mounting hole 120, and the diameter of the end of the guide wheel shaft 200 extending into the mounting hole 120 is not greater than the diameter of the mounting hole 120, and the diameter of the end of the guide wheel shaft 200 extending into the mounting hole 120 is greater than the diameter of the threaded hole 130. The connecting screw 220 passes through the through hole 210 and is threadedly connected with the threaded hole 130.

[0028] The utility model provides a cigarette making machine cloth belt guide wheel support shaft assembly, wherein the guide wheel base 100 is mounted on the back plate, the guide wheel bearing is mounted on the guide wheel shaft 200, and the cloth belt guide wheel is mounted on the guide wheel bearing. When the guide wheel bearing needs to be replaced, the connecting screw 220 is unscrewed, and then the guide wheel shaft 200 is removed, so that the guide wheel bearing and the cloth belt guide wheel can be removed together. After the guide wheel bearing is replaced, the cloth belt guide wheel is installed on the replaced guide wheel bearing, and then one end of the guide wheel shaft 200 is extended into the mounting hole 120, and the connecting screw 220 passes through the through hole 210 and is threadedly connected with the threaded hole 130, so that the guide wheel shaft 200 is connected to the guide wheel base 100. By using the cigarette making machine cloth belt guide wheel support shaft assembly, before replacing the guide wheel bearing, there is no need to disassemble the front workbench of the cigarette gun and the cigarette paper wheel protective cover, which saves time and effort, and a maintenance personnel can safely and easily realize the disassembly and installation of the guide wheel bearing.

[0029] In some embodiments, the number of the connection holes 111 is three, and the three connection holes 111 are evenly distributed around the connection portion 110, so that the guide wheel base 100 and the back plate are reliably connected. The M8 hexagon socket screw passes through the connection hole 111 and is threadedly connected to the back plate. The plane where the end of the guide wheel base 100 close to the connection portion 110 is located is perpendicular to the axis of the guide wheel shaft 200, thereby ensuring the verticality of the cloth belt guide wheel as a whole and the back plate, so that the cloth belt will not deviate when running.

[0030] In some embodiments, the outer wall of the guide wheel shaft 200 is provided with a shaft shoulder 230, and the shaft shoulder 230 can play an axial limiting role on the guide wheel bearing installed on the guide wheel shaft 200. Preferably, the distance between the end of the shaft shoulder 230 close to the guide wheel base 100 and the end of the guide wheel shaft 200 extending into the mounting hole 120 is not less than the depth of the mounting hole 120, so as to ensure that one end of the guide wheel shaft 200 smoothly extends into the mounting hole 120, and avoid interference between the shaft shoulder 230 and the guide wheel base 100.

[0031] Optionally, the outer wall of the guide wheel shaft 200 is provided with an axis groove 240, and the axis groove 240 is clamped with a retaining spring. Through the above structure, the retaining spring can limit the axial position of the guide wheel bearing. The retaining spring is used in conjunction with the shaft shoulder 230 to axially position the guide wheel bearing to prevent the guide wheel bearing from being offset.

[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
