Description

Technical Field

[0001] This utility model relates to the technical field of cigarette machine parts, specifically to a novel rubbing plate for cigarette machines. Background Technology

[0002] In the tobacco forming and conveying process of cigarette rolling machines, the rubbing plate is one of the core components that ensures the quality of cigarettes. Its working surface needs to be in direct contact with the tobacco continuously, undertaking the key functions of evenly spreading the tobacco, directional conveying, and assisting in cigarette rolling. The cleanliness and surface condition of the working surface directly determine the stability of tobacco conveying. Existing cigarette rolling machines face a significant problem of tobacco residue sticking to the rubbing plates during long-term operation. Tobacco naturally contains a small amount of tar and moisture during processing. When the tobacco rubs against the rubbing plate's working surface continuously, the heat generated by the mechanical movement accelerates the adhesion of this tar and moisture, causing the tobacco to gradually stick to the surface and form residue. Over time, this residue accumulates, disrupting the flatness of the rubbing plate's working surface and leading to localized accumulation or missed feeding of tobacco during subsequent conveying. In other words, if the rubbing plate surface is not cleaned promptly, the resulting cigarettes will not meet requirements. Based on this expertise, the technicians proposed a new type of rubbing plate for cigarette making machines, and constructed a solution by combining the working method between the rubbing plate and the drum of the cigarette making machine, the control system of the cigarette making machine itself, and the shape of the rubbing plate. Utility Model Content

[0003] The purpose of this invention is to improve upon existing washboards so that they have the ability to clean working surfaces.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A novel rubbing plate for cigarette making machines includes a rubbing plate body. A fixing plate is welded to the tail end of the rubbing plate body. The welding point between the fixing plate and the rubbing plate body is located at the lower edge of the tail end to form a standby area. Guide rails are provided on both sides of the rubbing plate body, and the guide rails follow the arc-shaped structure of the rubbing plate body. A traveling mechanism is provided on each of the two guide rails, and a scraping component for scraping the working surface of the rubbing plate body is connected between the two traveling mechanisms.

[0005] Furthermore, the guide rail consists of two upper and lower arc-shaped plates and a connecting plate connecting the two arc-shaped plates, with one end of the guide rail located in the standby area.

[0006] Furthermore, the walking mechanism includes a roller that is rolled between two arc-shaped plates and an arc-shaped toothed surface constructed on the bottom surface of the lower arc-shaped plate. A gear meshes with the arc-shaped toothed surface. A shaft is provided at the axis of both the roller and the gear. The shaft located at the roller rotates through the roller, and the shaft located at the gear is fixed to the gear.

[0007] Furthermore, a vertical plate is connected between the two shafts, and the shafts are rotatably connected to the vertical plate. A servo motor electrically connected to the cigarette machine control system is mounted on the vertical plate, and the output shaft of the servo motor is fixedly connected to the end of the shaft located at the gear.

[0008] Furthermore, the scraper is connected between two vertical plates, and an L-shaped mounting plate is fixed to the side of the upper arc plate. The L-shaped mounting plate is partially attached to the side of the scrubbing board body and has screw holes for fixing the guide rail to the side of the scrubbing board body.

[0009] Furthermore, the scraping component includes a connecting rod fixed to the two vertical plates, and a scraping brush is fixed below the connecting rod.

[0010] Furthermore, the scraping brush is a bristle brush or a rubber pad.

[0011] The beneficial effects of this utility model are as follows: 1. The walking mechanism and scraping parts of this utility model are all located in the standby area. This area is constructed by a fixed plate welded to the tail of the rubbing plate body (the fixed plate is welded to the lower edge of the tail end of the rubbing plate body). One end of the guide rail extends into the standby area. The rollers and gears of the walking mechanism are all located in the standby section of the guide rail, completely avoiding the working surface of the rubbing plate body and the mating area of ​​the drum, and not interfering with the operation of the original production structure of the cigarette machine.

[0012] 2. This utility model breaks through the traditional independent cleaning control approach by directly connecting the servo motor to the original control system of the cigarette machine. The cleaning timing is determined entirely by the original program: cleaning is only started when the rubbing plate moves away from the drum (non-production state), and automatically resets to standby when the rubbing plate approaches the drum (production state). No additional control module is needed, nor is manual triggering required, thus achieving seamless connection between "production and cleaning" and adapting to the continuous production rhythm of the cigarette machine.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0015] This embodiment provides a novel rubbing plate for a cigarette rolling machine, mainly used to improve upon existing rubbing plates, enabling them to clean the working surface. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation: A novel rubbing plate for cigarette making machines includes a rubbing plate body. The rubbing plate body is not significantly different from existing technologies, but the main improvements are as follows: a fixing plate is welded to the tail of the rubbing plate body, and the welding point between the fixing plate and the rubbing plate body is located at the lower edge of the tail end to form a standby area. At the same time, guide rails are provided on both sides of the rubbing plate body, and the guide rails follow the arc structure of the rubbing plate body. A traveling mechanism is provided on both guide rails, and a scraping component for scraping the working surface of the rubbing plate body is connected between the two traveling mechanisms.

[0016] Please see Figure 1 and Figure 5Specifically, the guide rail consists of two upper and lower arc-shaped plates and a connecting plate connecting the two arc-shaped plates. One end of the guide rail is located in the standby area. The traveling mechanism includes a roller that is rolled between the two arc-shaped plates and an arc-shaped toothed surface constructed on the bottom surface of the lower arc-shaped plate. A gear meshes with the arc-shaped toothed surface. A shaft is provided at the axis of both the roller and the gear. The shaft at the roller rotates through the roller, and the shaft at the gear is fixed to the gear. When the gear rotates, the roller cooperates to clamp onto the guide rail and moves under the guidance of the arc-shaped toothed surface. At the same time, in order to provide power, a vertical plate is connected between the two shafts. The shafts are rotatably connected to the vertical plate. A servo motor electrically connected to the cigarette machine control system is installed on the vertical plate. The output shaft of the servo motor is connected and fixed to the end of the shaft at the gear. During operation: the cigarette machine control system drives the rubbing plate body to approach the drum, entering the working state of tobacco spreading and conveying. All cleaning-related components, such as the walking mechanism and the scraper, are stored in the standby area. This area is constructed by a fixed plate welded to the tail of the rubbing board body, and one end of the guide rail is located in the standby area. The rollers and gears of the walking mechanism are all locked in the standby section of the guide rail, completely avoiding the mating area between the working surface of the rubbing board and the drum, and not affecting the operation of the original production structure of the cigarette machine.

[0017] Please see Figure 1 and Figure 3 The detailed structure of the scraper will be described in detail here. The scraper is connected between two vertical plates. An L-shaped mounting plate is fixed to the side of the upper arc plate. The L-shaped mounting plate is partially attached to the side of the washboard body and has screw holes for fixing the guide rail to the side of the washboard body. The scraper includes a connecting rod fixed to the two vertical plates. A scraping brush is fixed below the connecting rod. The scraping brush is a bristle brush or a rubber pad.

[0018] Working principle: S1: When the cigarette machine completes a single production cycle or reaches the preset cleaning cycle, the control system first drives the rubbing plate body away from the drum (out of the working position), and then sends a cleaning start signal to the servo motor electrically connected to the system.

[0019] S2: After the servo motor starts, its output shaft drives the shaft at the gear to rotate (the shaft is fixed to the gear); since the gear meshes with the arc tooth surface of the bottom of the lower arc plate of the guide rail, the gear moves along the arc tooth surface when it rotates, and at the same time drives the roller of the walking mechanism (5) to roll between the upper and lower arc plates of the guide rail (the roller passes through itself through the shaft and only plays a guiding role to avoid the walking mechanism from deviating); the vertical plate of the walking mechanism (the two shafts connecting the roller and the gear) moves synchronously with the gear and the roller, and then drives the scraper between the two vertical plates to move along the arc working surface of the rubbing board body. The scraper brush of the scraper (fixed below the connecting rod) is closely attached to the working surface to scrape off the residual tobacco and tobacco oil.

[0020] S3: When the scraping brush moves to the front end of the rubble board working surface (the end away from the standby area) and completes the cleaning of the entire working surface, the cigarette machine control system sends a reverse reset signal to the servo motor; the servo motor rotates in the opposite direction, driving the gears and rollers to move in the opposite direction along the arc-shaped tooth surface of the guide rail and the upper and lower arc plates until the walking mechanism and scraping parts return to the standby area; then the control system drives the rubble board body to approach the drum again to enter the next round of production, and the cleaning process ends.

[0021] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
