Description

Technical Field

[0001] The present invention relates to the field of the tobacco industry, and particularly relates to a transmission method for on-line changing equal-spacing filter rods into non-equal-spacing filter rods. Background Art

[0002] The solid parts in cigarette filters are mainly used for the filter part of cigarettes. Their structures are diverse and may include cylindrical shells, end faces, and internal fillers, etc. These solid parts are designed to improve the taste of the smoke and reduce the intake of harmful substances. They can filter out some harmful substances in the smoke, such as tar, nicotine, etc., and may also add spices or other components to improve the taste of the smoke.

[0003] Generally, the solid parts are placed between two filter rods. There are also a small number of solid parts combined with a single filter rod. To insert the solid parts into the threading wires of the filter rods, it is necessary to adjust the spacing between the equal-spacing filter rods. Currently, only the spacing between the equal-spacing filter rods can be enlarged through a dial, and the spacing between the filter rods cannot be adjusted intermittently, that is, it cannot meet the setting of some special-length solid parts between the filter rods. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides a transmission method for on-line changing equal-spacing filter rods into non-equal-spacing filter rods, aiming to adjust the spacing between the filter rods where the solid parts need to be inserted, so as to reduce unnecessary operations and thus improve work efficiency.

[0005] A transmission method for on-line changing equal-spacing filter rods into non-equal-spacing filter rods includes a first transmission line, a second transmission line, and a dial transmission mechanism. The dial transmission mechanism is provided with an arc-shaped channel and a dial. Fixed dial teeth fixedly connected to the dial are distributed on the circumference of the dial. The arc-shaped channel is arranged around the circumference of the dial and the fixed dial teeth are located in the arc-shaped channel. The two ends of the arc-shaped channel are respectively communicated with the first transmission line and the second transmission line, and the dial rotates at a constant speed. The transmission method includes the following steps:

[0006] Step 1: Set swing dial teeth on the circumference of the dial and make the swing dial teeth swing along the circumferential direction of the dial within a fixed angular range.

[0007] Step 2: Position the swing dial teeth at a first angular position and rotate synchronously with the dial, and make the swing dial teeth and the fixed dial teeth evenly distributed on the circumference of the dial.

[0008] Step 3: Use the swing dial teeth and the fixed dial teeth to sequentially dial the equal-spacing filter rods on the first transmission line through the arc-shaped channel to the second transmission line.

[0009] When the swing pick tooth toggles the filter rod into the arc-shaped channel, the swing pick tooth swings relative to the dial in the opposite direction of the dial rotation. At this time, the distance between the filter rod toggled by the swing pick tooth and its pre-positioned filter rod becomes longer. When the distance between this filter rod and its pre-positioned filter rod reaches the set distance, the swing pick tooth is positioned at the second angular position and rotates synchronously with the dial.

[0010] When the swing pick tooth at the second angular position toggles the filter rod onto the second transmission line, the non-uniform spacing adjustment between the filter rods is completed.

[0011] Furthermore: The transmission speed of the second transmission line ≥ the linear speed of the dial circumference ≥ the transmission speed of the first transmission line.

[0012] Furthermore: The swing pick teeth and the fixed pick teeth are alternately distributed on the dial.

[0013] Furthermore: The dial is rotationally installed on the base and driven to rotate by a driving mechanism. A counterbore is provided on the base, and the dial is accommodated in the counterbore. An arc-shaped channel is formed between the outer circumference of the dial, the side wall of the counterbore, and the bottom wall of the counterbore. The inlet of the arc-shaped channel is opened at the side wall and the bottom wall of the counterbore, and the outlet of the arc-shaped channel is opened at the bottom wall and the side wall of the counterbore.

[0014] Furthermore: A swing rod is swingably arranged on the dial. The outer end of the swing rod is fixedly connected to the inner end of the swing pick tooth, so that the swing pick tooth moves synchronously with the swing rod. A limiting groove is provided on the dial at the position corresponding to the swing rod. The two side walls of the limiting groove are respectively located on both sides of the swing rod and are used to block the swing rod to limit its swing limit, thereby limiting the first angular position and the second angular position of the swing pick tooth.

[0015] Furthermore: A return spring is provided on the dial. One end of the return spring is fixedly connected to the dial, and the other end of the return spring is fixedly connected to the swing rod. The return spring is used to return the swing rod from the second angular position to the first angular position. A damping plate is fixedly provided above the swing rod and at the position corresponding to the outlet end of the arc-shaped channel. The damping plate is used to apply a damping force to the swing rod and make the swing rod swing to the second angular position after overcoming the pulling force of the return spring.

[0016] Furthermore: The dial is set as an annular disc structure. The dial includes an upper disc and a lower disc that are fixedly connected after docking. The arc-shaped channel is located between the upper disc and the side wall of the counterbore. The fixing part of the fixed pick tooth extends below the bottom surface of the upper disc and is fixedly connected to the upper disc or the lower disc. The limiting groove is located on the bottom surface of the upper disc. The swing rod passes through the limiting groove, and the inner end of the swing rod passes out from the inner circle of the dial and is connected to the return spring.

[0017] Further, the inner end of the swing rod is fixedly connected to the outer ring of the bearing. The bearing is horizontally arranged and sleeved on the vertical fixed shaft. The fixed shaft is located at the center of the dial and fixedly connected to the base.

[0018] Further, the inner end of the swing rod bulges upward to form a friction part. When the friction part moves to the damping plate, its top surface rubs against the bottom surface of the damping plate and moves. The swing rod is limited by one side wall of the limiting groove, so that the swing tooth is positioned at the second angular position. After the friction part separates from the damping plate, the return spring pulls the swing rod to the other side wall of the limiting groove, so that the swing tooth resets and is positioned at the first angular position.

[0019] Further, the damping plate is fixedly connected above the dial through a fixing frame. The fixing frame is fixedly connected to the base. Vertically arranged screws are rotatably installed at both ends of the damping plate, and the upper ends of the screws are in threaded cooperation with the fixing frame.

[0020] The beneficial effects of the present invention: By arranging a swing tooth with a first angular position and a second angular position on the dial, during the process of moving the filter rod from the first transmission line to the second transmission line, the distance between the filter rod and the filter rod in its previous position is adjusted, so that the filter rods are arranged at non-uniform intervals on the second transmission line, which is convenient for inserting special-length fasteners between the filter rods.

[0024] The following will describe the present invention in detail with reference to the drawings. The embodiments of the present invention will be described in detail below. The examples are shown in the drawings, and the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention. The azimuth terms such as left, middle, right, up, and down in the embodiments of the present invention are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0025] A transmission method for on-line dialing equal-spacing filter rods into non-equal-spacing, in combination with Figure 2 and Figure 3As shown, it includes a first transmission line 101, a second transmission line 103 and a dial transmission mechanism. The dial transmission mechanism is provided with an arc-shaped channel 102 and a dial 1. Fixed teeth 7 fixedly connected to the dial 1 are distributed on the circumference of the dial 1. The arc-shaped channel 102 is arranged around the circumference of the dial 1 and the fixed teeth 7 are located within the arc-shaped channel 102. The two ends of the arc-shaped channel 102 are respectively communicated with the first transmission line 101 and the second transmission line 103, and the dial 1 rotates at a constant speed; As Figure 1 shown, the transmission method includes the following steps:

[0026] Step 1: A swinging tooth 2 is arranged on the circumference of the dial 1, and the swinging tooth 2 swings along the circumferential direction of the dial 1 within a fixed angular range;

[0027] Step 2: The swinging tooth 2 is positioned at the first angular position and rotates synchronously with the dial 1, and the swinging tooth 2 and the fixed teeth 7 are evenly distributed on the circumference of the dial 1. Preferably, the swinging tooth 2 and the fixed teeth 7 are alternately distributed on the circumference of the dial 1;

[0028] Step 3: The filter rods 104 at equal intervals on the first transmission line 101 are successively dialed through the swinging tooth 2 and the fixed teeth 7 to the second transmission line 103 via the arc-shaped channel 102;

[0029] When the swinging tooth 2 dials the filter rod 104 into the arc-shaped channel 102, the swinging tooth 2 swings relative to the dial 1 in the opposite direction of the rotation of the dial 1. Since the swinging tooth 2 lags behind the normal moving position, the filter rod 104 stops moving or its moving speed slows down. At this time, the distance between the filter rod 104 dialed by the swinging tooth 2 and its pre-positioned filter rod 104 becomes longer, and when the distance between the filter rod 104 and its pre-positioned filter rod 104 reaches the set distance, the swinging tooth 2 is positioned at the second angular position and rotates synchronously with the dial 1; Among them, the meaning of pre-positioned is that when the dial rotates, it is in front of the rotation direction;

[0030] When the swinging tooth 2 at the second angular position dials the filter rod 104 to the second transmission line 103, the non-uniform spacing adjustment between the filter rods 104 is completed.

[0031] Among them, the transmission speed of the second transmission line ≥ the linear speed of the dial circumference ≥ the transmission speed of the first transmission line. When the transmission speed of the second transmission line and the linear speed of the dial circumference are larger, the distance between the filter rods can be enlarged;

[0032] For the convenience of setting the arc-shaped channel, the dial 1 is rotatably installed on the base 6 and driven to rotate by a driving mechanism. A counterbore 61 is formed on the base 6, and the dial 1 is accommodated in the counterbore 61. An arc-shaped channel 102 is formed between the outer circumference of the dial 1, the side wall of the counterbore 61, and the bottom wall of the counterbore 61. The inlet of the arc-shaped channel 102 is formed at the side wall and the bottom wall of the counterbore 61, and the outlet of the arc-shaped channel 102 is formed at the bottom wall and the side wall of the counterbore 61. That is, two notches are formed at the side wall and the bottom wall of the counterbore 61, and these two notches respectively form the inlet and the outlet of the arc-shaped channel 102;

[0033] To achieve the swing of the swing tooth 2 on the dial 1, a swing rod 3 is swingably arranged on the dial 1. The outer end of the swing rod 3 is fixedly connected to the inner end of the swing tooth 2, so that the swing tooth 2 moves synchronously with the swing rod 3. A limiting groove 12 is formed at the position corresponding to the swing rod 3 on the dial 1. The two side walls of the limiting groove 12 are respectively located on both sides of the swing rod 3 and are used to stop on the swing rod 3 to limit its swing limit, thereby limiting the first angular position and the second angular position of the swing tooth 2. To facilitate the control of the swing of the swing rod 3, a return spring 4 is arranged on the dial 1. One end of the return spring 4 is fixedly connected to the dial 1, and the other end of the return spring 4 is fixedly connected to the swing rod 3. The return spring 4 is used to return the swing rod 3 from the second angular position to the first angular position. A damping plate 5 is fixedly arranged above the swing rod 3 and at the position corresponding to the outlet end of the arc-shaped channel 102. The damping plate 5 is used to apply a damping force to the swing rod 3 and make the swing rod 3 swing to the second angular position after overcoming the pulling force of the return spring 4. The damping plate 5 is fixedly connected above the dial 1 through a fixing frame 52, and the fixing frame 52 is fixedly connected to the base 6. Vertical screws 51 are rotatably installed at both ends of the damping plate 5. The upper ends of the screws 51 are in threaded cooperation with the fixing frame 52, so that the height position of the damping plate 5 can be adjusted through the screws 51, and further the friction between the damping plate 5 and the swing rod 3 can be adjusted. To facilitate the arrangement of the fixed tooth 7 and the swing tooth 2 on the dial 1, the dial 1 is set as an annular disc structure. The dial 1 includes an upper disc 11 and a lower disc 13 which are fixedly connected after being butted. The upper disc 11 and the lower disc 13 are concentrically arranged. The diameter of the upper disc 11 is smaller than that of the lower disc 13. The arc-shaped channel 102 is located between the side wall of the upper disc 11 and the sinking groove 61. The fixing part of the fixed tooth 7 extends below the bottom surface of the upper disc 11 and is fixedly connected to the lower disc 13 or the upper disc 11. The limiting groove 12 is located on the bottom surface of the upper disc 11 and between the upper disc 11 and the lower disc 13. The swing rod 3 is inserted into the limiting groove 12. The inner end of the swing rod 3 passes through the inner ring of the dial 1 and is connected to the return spring 4. To facilitate the swing of the swing rod 3, the outer ring of a bearing 32 is fixedly connected to the end of the inner end of the swing rod 3. The bearing 32 is horizontally arranged and sleeved on a vertical fixed shaft 33. The fixed shaft 33 is located at the center of the dial 1 and is fixedly connected to the base 6. To facilitate the damping effect of the damping plate 5 on the swing rod 3, the end of the inner end of the swing rod 3 bulges upward to form a friction part 31. When the friction part 31 moves to the damping plate 5, its top surface rubs against the bottom surface of the damping plate 5, and the swing rod 3 is limited by one side wall of the limiting groove 12, so that the swing tooth 2 is positioned at the second angular position. After the friction part 31 is separated from the damping plate 5, the return spring 4 pulls the swing rod 3 to the other side wall of the limiting groove 12, so that the swing tooth 2 is reset and positioned at the first angular position.
