Description
Technical Field
[0001] This utility model belongs to the field of cigarette production technology, specifically relating to a tow spread control device. Background Technology
[0002] Air openers are core equipment in cigarette filter manufacturing. Their core function is to use low-pressure airflow to laterally spread the filament bundle (such as cellulose acetate), primarily increasing and stabilizing the width of the filament bundle, slightly widening and smoothing it, and removing loose, overlapping, or twisted fibers (such as...). Figure 1 Currently, during the opening process of the air opener for fiber bundles, if the width of the fiber bundle is too wide, there are too many fuzzy filaments on the air opener (especially the main air opener), and the fiber bundles are stranded, it will lead to poor fiber bundle opening, affecting the filter rod's suction resistance, and in severe cases, causing the filter rod to become soft. To solve this problem, enterprise standards are currently formulated based on the actual conditions of the equipment, and the opening width is usually controlled at 225 ± 30 mm. Currently, the fiber bundle width control device includes a baffle, a horizontal plate, and a cylinder. One end of the horizontal plate is a baffle, and the other end is a cylinder. The cylinder and the horizontal plate are fixed together by bolts (e.g., ...). Figure 2 The distance between the two baffles is the width of the filament bundle. The method to adjust the width is to manually adjust the position of the cylinder relative to the fixed baffle and fix the position of the cylinder with bolts. Due to the safety settings of the KDF4 molding machine, the operator needs to stop the machine and open the protective cover to adjust the width, which is very laborious.
[0003] In addition, during the opening process of the air opener, the ends of the filaments are in contact with the baffle for a long time, and the sides of the filaments are in severe friction with the baffle, resulting in a large amount of fly filaments. The fly filaments will adhere to the glycerin spray chamber, and the residual filaments mixed with glycerin will corrode the filter rod and produce glue holes (melt holes). In order to avoid this problem, the fly filaments need to be cleaned frequently during the opening process, which is very time-consuming and labor-intensive.
[0004] To address the above problems, this utility model is proposed. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes an improved device for a filament spreader baffle, which aims to reduce filament fly and enable online adjustment of spread.
[0006] This utility model provides a filament spread control device, which includes a needle roller bearing 1, an L plate 2, a miniature cylinder 3, and a base 4;
[0007] The bottom of the miniature cylinder 3 is fixed to the upper part of the base 4, wherein the base 4 is placed vertically and the miniature cylinder 3 is placed horizontally;
[0008] The micro cylinder 3 has a cylinder extension rod 31 at the end away from the base 4 (i.e., the upper part of the micro cylinder 3).
[0009] One end of the L-plate 2 is fixedly nested on the cylinder extension rod 31, and the other end of the L-plate 2 is sleeved in the needle roller bearing 1;
[0010] The axis of the needle roller bearing 1 is perpendicular to the axis of the miniature cylinder 3;
[0011] The miniature cylinder 3 drives the needle roller bearing 1 to move in the horizontal direction (the direction of the axis of the miniature cylinder 3) through the cylinder extension rod 31.
[0012] Preferably, the axis of the miniature cylinder 3 is parallel to the axis of the opening rubber roller, such as... Figure 1 The position of the loosened rubber roller can be seen from the image.
[0013] Preferably, the upper part of the base 4 has a groove hole 41, the bottom of the miniature cylinder 3 has a through hole, the first bolt 5 passes through the groove hole 41 and the through hole, and the bottom of the miniature cylinder 3 is fixed to the upper part of the base 4 by a nut.
[0014] Preferably, the base 4 is welded to the wall panels on both sides of the wire bundle to facilitate fixing the base 4.
[0015] Preferably, one end of the L plate 2 is fixedly nested on the cylinder extension rod 31 by fastening bolts 6.
[0016] Preferably, the air tube is connected to a throttle valve and then to a three-position three-way solenoid valve, with two manual buttons connected to the coil control terminals of the three-position three-way solenoid valve respectively.
[0017] The two manual buttons refer to the forward and backward buttons, and their specific controls are as follows:
[0018] When the forward button is pressed, the solenoid valve switches from stop to piston bottom air intake mode, and the cylinder extension rod 31 extends.
[0019] When the reverse button is pressed, the solenoid valve switches from stop to exhaust port intake mode, and the cylinder extension rod 31 retracts.
[0020] When neither the forward nor the reverse button is pressed, the solenoid valve is in a stopped state, and the miniature cylinder 3 is in a stopped state.
[0021] Preferably, the two sets of the filament spread control devices are placed facing each other and used in combination, wherein the distance between the two needle roller bearings 1 is the opening width, and the filament tape to be processed is located between the two needle roller bearings 1.
[0022] Preferably, the miniature cylinder 3 drives the needle roller bearing 1 to move in the horizontal direction (the direction of the axis of the miniature cylinder 3) through the cylinder extension rod 31, thereby adjusting the distance between the two needle roller bearings 1 and realizing the online adjustment of the opening and closing width.
[0023] When the forming machine is running normally, the two sides of the filament belt contact the surface of the needle roller bearing and drive the needle roller bearing to rotate. When it is necessary to adjust the filament width, the manual button is pressed and the cylinder corresponding to the solenoid valve is activated.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. In the fiber bundle spreading control device of this utility model, the one in contact with the fiber bundle is the needle roller bearing 1. The sliding friction between the fiber bundle and the baffle is changed to the rotational friction between the fiber bundle and the needle roller bearing, which can reduce fly shavings and thus avoid the problem that the fly shavings attached to the glycerin spray chamber will cause corrosion to the filter rod after the residual fibers are mixed with glycerin, resulting in glue holes (melting holes).
[0026] 2. In this utility model, the two sets of filament spread control devices are placed facing each other and used in combination. The distance between the two needle roller bearings 1 is the spread width, and the filament belt to be processed is located between the two needle roller bearings 1. When it is necessary to adjust the filament belt width, the micro cylinder 3 drives the needle roller bearings 1 to move horizontally through the cylinder extension rod 31, thereby adjusting the distance between the two needle roller bearings 1, and realizing online adjustment of the filament belt width by manually pressing a button.
