Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarettes, in particular to a structural improvement of a paper feeding mechanism of a filter rod forming machine. Background Art
[0002] The filter rod production process requires wrapping silk fibroin with paper to compress it into a cylindrical shape. During the operation of existing filter rod forming machines, the paper feed mechanism is powered by a terminal drag. In actual production, especially after the equipment has been running for a long time, the single-powered drag mechanism can lead to insufficient power and uneven force on the paper surface. This can cause quality issues such as wrinkles and deflated filter rods, resulting in uneven wrapping of the silk fibroin within the filter rods. This significantly reduces product qualification rates and severely impacts normal production. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide an improved structure of the paper feeding mechanism of a filter rod forming machine in order to solve the problems of wrinkles, deflated rods and the like caused by insufficient power of the forming paper and unstable operation in the production of filter rods.
[0004] The technical solution of the present utility model is: an improved structure of the paper feeding mechanism of a filter rod forming machine, comprising a terminal dragging device and a passive paper guide roller, the forming paper is pulled by the terminal dragging device to the filter rod forming mechanism for paper feeding, an active paper guide device is also provided on the route of the forming paper, the active paper guide device comprises a connecting seat, a servo motor, an active paper guide roller and a paper guide roller shaft, the connecting seat is a cylindrical body, the middle position and one end of the connecting seat are respectively provided with flanges connected to the filter rod forming machine frame and the servo motor, the connecting seat is connected to the servo motor by bolts and fixed to the frame by bolts, the active paper guide roller is fixed to one end of the paper guide roller shaft, the other end of the paper guide roller shaft is provided with a spline connecting groove, the paper guide roller shaft passes through the cylindrical cavity of the connecting seat and is connected to the motor shaft by a spline, and is rotatably connected to the connecting seat by a bearing, two passive paper guide rollers are provided next to the active paper guide device to wrap the forming paper around the active paper guide roller in a "U" shape.
[0005] The technical effect of this utility model is that it can provide additional power to the paper web during its operation, enabling it to run quickly and stably, solving the problems of wrinkles and deflated paper. Wrinkles caused by the paper web being subjected to pulling force alone no longer occur, significantly improving product quality, pass rate, and production speed, greatly benefiting enterprises in increasing production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 It is a structural diagram of the utility model;
[0007] Figure 2 This is a schematic structural diagram of the active paper guiding device of the present utility model. DETAILED DESCRIPTION
[0008] like Figure 1 and 2 As shown, an improved structure of the paper feeding mechanism of a filter rod forming machine includes a terminal dragging device and a passive paper guide roller 1. The forming paper 2 is pulled by the terminal dragging device to the filter rod forming mechanism for paper feeding. An active paper guiding device 3 is also provided on the route of the forming paper 2. The active paper guiding device 3 includes a connecting seat 4, a servo motor 5, an active paper guide roller 6 and a paper guide roller shaft 7. The connecting seat 4 is a cylindrical body. The middle position and one end of the connecting seat 4 are respectively provided with flanges connected to the filter rod forming machine frame and the servo motor 5. The connecting seat 4 is connected to the servo motor 5 by bolts and fixed to the frame by bolts. The active paper guide roller 6 is fixed to one end of the paper guide roller shaft 7, and the other end of the paper guide roller shaft 7 is provided with a spline connecting groove. The paper guide roller shaft 7 passes through the cylindrical cavity of the connecting seat 4 and is connected to the motor shaft by a spline, and is rotatably connected to the connecting seat 4 by a bearing. Two passive paper guide rollers 1 are provided next to the active paper guiding device 3 to wrap the forming paper 2 around the active paper guide roller 6 in a "U" shape. The active paper guide is located in the middle of the paper's path and is connected to the machine frame through a hole in the housing. The surface of the active paper guide roller is made of a material with a certain coefficient of friction to ensure that the paper is adequately powered.
[0009] The flanges where the connecting seat 4 and the servo motor 5 are connected are both provided with shoulders for embedding bearings, and the two together embed the bearings in the shoulders. The shoulder settings of the two can make the bearings play a role in alignment.
[0010] A spline sleeve 8 with key teeth on its outer circumference is fixed to the motor shaft of the servo motor 5 , and the motor shaft is connected to the connecting seat 4 through the spline sleeve 8 .
[0011] The spline sleeve 8 is connected to the motor shaft of the servo motor 5 via a key.
[0012] The end of the paper guide roller shaft 7 is connected to a pressure cover 9 by bolts and abuts against the active paper guide roller 6.
[0013] The active paper guide roller driven by a servo motor is installed in the middle of the paper web running path of the filter rod forming machine. The paper guide roller is driven to rotate by its independent servo motor, and the paper web is powered by the paper guide roller. Since the paper web is no longer subjected to a single drag force during operation, the forming paper can completely and evenly wrap the fibroin, completely solving the problems of wrinkles and deflated rods in the product.
