Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machine equipment, in particular to a loosening and stabilizing device for cigarette filter tows. Background Art

[0002] Diacetate fiber tow is widely used as cigarette filter material. Diacetate fiber tow is made of natural wood pulp as raw material, which is processed into diacetate cellulose sheets through acetification, dissolution, filtration, spinning, curling, drying and other production processes. This regenerated cellulose fiber has good moisture absorption and adsorption, and has certain elasticity. The interface of diacetate fiber tow is "Y" shaped, and the surface area of ​​cellulose is large, which has good adsorption and interception effect on harmful components in cigarette smoke.

[0003] The diacetate fiber tow is packed and shipped to all parts of the country by the manufacturer. The tight packing by the manufacturer will have a certain impact on the internal stress of the tow itself, and the different temperatures and humidity in various regions of the country will also have a certain impact on the tow during transportation and storage. The characteristics and stability of the tow itself play a decisive role in the suction resistance, hardness and quality of the filter rod. Because most filter rod factories and cigarette factories cannot have absolute control over the storage and use environment of the tow (temperature is 24℃±2, humidity is 60±5); and after the tow is packed, it is under heavy pressure, which will also affect its tension, stress, flying wires, etc., so during the filter rod production process, the fluctuation of the filter rod suction resistance will be relatively large.

[0004] In the prior art, the yarn bundle is usually pulled directly. The compression force at the corners of the yarn bundle is relatively large due to the packaging of the yarn bundle, which causes the tension of the yarn bundle to change during the pulling process. As the yarn bundle is used, the pulling position is gradually lowered, and the pulling force of the yarn bundle will also change accordingly. The change in tension will cause the tension of the yarn bundle to change continuously during the opening process, and the opening is unstable. In addition, the change in tension of the yarn bundle during the opening process will cause the yarn bundle to form broken yarns and flying yarns, resulting in large fluctuations in the absorption resistance of the yarn bundle and a large standard deviation of the absorption resistance.

By setting a motor, an active roller and a pressure roller, the motor drives the active roller to rotate, so that the tow can be transported along the outer wall of the active roller and the pressure roller as the active roller rotates, thereby sequentially compressing and opening the tow, thereby avoiding the stress and tension generated when the tow is packaged and transported. The tension in the tow drawing process causes the tow to break and fly when opening, thereby avoiding the large fluctuation of the suction resistance of the tow, the large standard value of the suction resistance, etc., making the opening of the tow more stable, the fluctuation of the suction resistance and the standard value of the suction resistance more stable, thereby reducing the problem of glue holes caused by flying wires.

[0022] 2. The utility model is a device for stabilizing the loosening of cigarette filter tows. By setting a pushing mechanism, the pressing roller can be driven to move toward or away from the active roller. When the tow is pulled out of the tow package, the tow is attached to the outer wall of the pressing roller, and then the pushing mechanism is driven to drive the pressing roller to move toward the active roller, so that the tow is clamped between the active roller and the pressing roller, thereby achieving the loosening of the tow. The pushing mechanism includes a cylinder, a swing plate, a first rotating shaft and a second rotating shaft. The cylinder extends to drive the swing plate to rotate around the axis of the second rotating shaft. Since the pressing roller is connected to the side wall of the swing plate, the pressing roller can move with the rotation of the swing plate, thereby reducing the gap between the pressing roller and the active roller to achieve the compression of the tow.

[0023] 3. The utility model is a loosening and stabilizing device for cigarette filter tow, which can limit the conveying path of the tow by setting a plurality of guide rollers, so that the tow is conveyed along a predetermined route. By setting a plurality of blocking rollers, it can prevent the tow from being rewound around the active roller due to the passing of operators below during the conveying process due to the low weight of the tow, thereby preventing the tow from being disorderly, and further preventing the tow from being torn or multiple layers of tow from being mixed together, resulting in reduced quality of the tow.

[0024] 4. The utility model is a device for stabilizing the loosening of cigarette filter tows. By setting a protective plate, it can prevent the operator from accidentally touching the active roller or the pressure roller, thereby preventing the operator from being clamped by the pressure roller and the active roller, thereby improving safety. By setting a detection mechanism, it can detect the sag of the tow and change the speed of the motor according to the height of the sag of the tow; when the sag of the tow is low, the detection mechanism reduces the motor speed, thereby increasing the sag of the tow; when the sag of the tow is high, the detection mechanism increases the motor speed, thereby reducing the sag of the tow.

[0025] 5. The utility model is a device for stabilizing the opening of cigarette filter tows. The detection mechanism includes a mounting rod, a mounting frame, a support frame, a sensor and a rotating member. The sensor can change the height of the sensor on the mounting frame to adapt to the detection of the sag of tows at different heights. By sleeved with a rotating member on the mounting rod, the detection angle of the sensor can be changed, thereby changing the detection direction of the sensor. The detection mechanism can be more adapted to the detection of the sag of different tows, making the detection more comprehensive and convenient. By opening two long through holes on the mounting frame and correspondingly opening two mounting holes on the support frame, the support frame can be moved vertically on the mounting frame, thereby changing the detection height of the sensor. At the same time, the two long through holes and the two mounting holes can make the support frame more stable when installed on the mounting frame.

[0026] 6. The utility model is a device for loosening and stabilizing the cigarette filter tow, which installs a hanging ring on the bottom wall of the top of the frame. The tow passes through the hanging ring, which can limit the conveyance of the tow to prevent the tow from fluttering due to wind and other factors, thereby preventing the tow from being reversely rolled into the gap between the active roller and the pressure roller.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] Embodiment 1

[0035] like Figure 1-4As shown, a loosening and stabilizing device for cigarette filter tow in this embodiment includes a frame 1 in which the tow 2 can be placed, and an opening component 3 installed on the top of the frame 1.

[0036] Specifically, Figure 2 As shown, the loosening assembly 3 includes a base plate 31, a pressure roller 32, an active roller 33 and a motor 34. The base plate 31 is vertically installed on the top of the frame 1. The pressure roller 32 and the active roller 33 are both installed in parallel on the side wall of the base plate 31 on the same side. There is a gap between the active roller 33 and the pressure roller 32 for passing the yarn bundle 2. The motor 34 is installed on the side wall on the other side of the base plate 31 and the output shaft of the motor 34 passes through the base plate 31 and is connected to the active roller 33, so that the active roller 33 and the pressure roller 32 can press and loosen the yarn bundle 2. By setting a motor 34, an active roller 33 and a pressure roller 32, the motor 34 drives the active roller 33 to rotate, so that the yarn bundle 2 can be transported along the outer walls of the active roller 33 and the pressure roller 32 as the active roller 33 rotates, thereby the yarn bundle 2 is pressed and loosened in sequence, thereby avoiding the stress and tension generated when the yarn bundle 2 is packaged and transported. The pulling force during the pulling process of the yarn bundle 2 causes the yarn bundle 2 to break or fly when it is loosened, thereby avoiding large fluctuations in the suction resistance of the yarn bundle 2 and large standard values ​​of the suction resistance. The loosening of the yarn bundle 2 is more stable, the fluctuation of the suction resistance and the standard value of the suction resistance are more stable, and the problem of glue holes caused by flying threads is reduced.

[0037] Furthermore, the opening assembly 3 also includes a plurality of guide rollers 36; the tail ends of the plurality of guide rollers 36 are installed on the side wall of the base plate 31 and are located on the same side of the base plate 31 as the active roller 33 and the pressure roller 32, and the plurality of guide rollers 36 are located below the active roller 33 and the pressure roller 32, which can limit the conveying path of the filament bundle 2 so that the filament bundle 2 is conveyed along a predetermined route.

[0038] Furthermore, the opening assembly 3 further includes a plurality of stop rollers 37; the tail ends of the plurality of stop rollers 37 are mounted on the side wall of the base plate 31 on the same side as the active roller 33, and the plurality of stop rollers 37 are located on the periphery of the active roller 33 on the side away from the pressing roller 32. The plurality of stop rollers 37 can prevent the tow 2 from being wound around the active roller 33 again due to the passing of operators below during the conveying process due to the low weight of the tow 2, thereby preventing the tow 2 from being disordered, and further preventing the tow 2 from being torn or multiple layers of tow 2 from being mixed together, resulting in a reduction in the quality of the tow 2. Preferably, the opening assembly 3 further includes a protective plate 38 and a lifting ring 4; the protective plate 38 is an L-shaped plate, the bottom wall of the horizontal plate 381 of the protective plate 38 is connected to the top of the base plate 31, and the inner wall of the vertical plate 382 of the protective plate 38 is connected to the front end of the active roller 33, the front end of the pressure roller 32 and the front end of the plurality of stop rollers 37, which can prevent the operator from accidentally touching the active roller 33 or the pressure roller 32, thereby preventing the operator from being clamped by the pressure roller 32 and the active roller 33, thereby improving safety. The lifting ring 4 is installed on the bottom wall of the top of the frame 1, and the tow 2 passes through the lifting ring 4 and is placed in the gap between the active roller 33 and the pressure roller 32 along the outer wall of the pressure roller 32. The tow 2 passes through the lifting ring 4, which can limit the conveying of the tow 2, prevent the tow 2 from floating due to other factors such as wind, thereby preventing the tow 2 from being reversely rolled into the gap between the active roller 33 and the pressure roller 32.

[0039] Furthermore, the opening assembly 3 further includes a pushing mechanism 35; the pushing mechanism 35 is installed on the side wall of the base plate 31, and the pushing mechanism 35 is connected to the tail end of the pressing roller 32, and the pushing mechanism 35 can drive the pressing roller 32 to move in the direction close to or away from the active roller 33, so as to reduce the gap between the active roller 33 and the pressing roller 32. By setting the pushing mechanism 35, it can drive the pressing roller 32 to move in the direction close to or away from the active roller 33. When the tow 2 is pulled out from the tow 2 package, the tow 2 is attached to the outer wall of the pressing roller 32, and then the pushing mechanism 35 is driven to drive the pressing roller 32 to move in the direction close to the active roller 33, so that the tow 2 is clamped between the active roller 33 and the pressing roller 32, so as to realize the opening of the tow 2.

[0040] Specifically, Figure 3As shown, the pushing mechanism 35 includes a cylinder 351, a swing plate 352, a first rotating shaft 353 and a second rotating shaft 354; the cylinder 351 is rotatably mounted on the side wall of the base plate 31 through the first rotating shaft 353, the protruding end of the cylinder 351 is hinged to the swing plate 352, the swing plate 352 is rotatably mounted on the side wall of the base plate 31 through the second rotating shaft 354, and the tail end of the clamping roller 32 is fixedly mounted on the swing plate 352; the protruding end of the cylinder 351 can drive the swing plate 352 to rotate around the axis of the second rotating shaft 354, so as to drive the clamping roller 32 to move towards or away from the active roller 33. By setting up the cylinder 351, when the cylinder 351 is extended, it can drive the swing plate 352 to rotate around the axis of the second rotating shaft 354. Since the pressure roller 32 is connected to the side wall of the swing plate 352, the pressure roller 32 can move with the rotation of the swing plate 352, thereby reducing the gap between the pressure roller 32 and the active roller 33 to achieve the compression of the filament bundle 2.

[0041] Furthermore, the opening assembly 3 further includes a detection mechanism 39 and an electric control box 5; the detection mechanism 39 is mounted on the base plate 31 and is located at one end of the base plate 31 away from the active roller 33, the electric control box 5 is mounted on the top wall of the frame 1, the detection mechanism 39 is electrically connected to the electric control box 5, and the electric control box 5 is electrically connected to the motor 34, and the detection mechanism 39 is used to detect the sag of the tow 2. By setting the detection mechanism 39, it can detect the sag of the tow 2, and it can change the speed of the motor 34 according to the height of the sag of the tow 2; when the sag of the tow 2 is low, that is, when the detection mechanism 39 detects the tow 2, the detection mechanism 39 reduces the speed of the motor 34 to reduce the conveying speed of the tow 2, thereby increasing the sag of the tow 2; when the sag of the tow 2 is high, that is, when the detection mechanism 39 cannot detect the tow 2, the detection mechanism 39 increases the speed of the motor 34 to speed up the conveying speed of the tow 2, thereby reducing the sag of the tow 2.

[0042] It should be noted that the detection mechanism 39 can transmit an electrical signal to the PLC module in the electric control box 5, and the PLC module sends an analog quantity to the motor 34, thereby changing the speed of the motor 34; in addition, it should be noted that this embodiment does not involve the improvement and use of any computer program, but only provides the connection relationship between the detection mechanism 39, the electric control box 5 and the motor 34. The improvement of the utility model does not involve the content of control, and the existing control process is all existing content.

[0043] Specifically, Figure 4As shown, the detection mechanism 39 includes a mounting rod 391, a mounting frame 392, a supporting bracket 393, a sensor 394 and a rotating member 395; the mounting rod 391 is installed on the side wall of the substrate 31, the rotating member 395 is sleeved on the mounting rod 391, the top of the mounting frame 392 is connected to the rotating member 395, the sensor 394 is installed on the mounting frame 392 through the supporting bracket 393, and the supporting bracket 393 can change the height on the mounting frame 392 and the sensor 394 can rotate around the axis of the rotating member 395 to change the detection angle of the sensor 394. By setting up the mounting frame 392, the height of the sensor 394 can be changed on the mounting frame 392, so as to adapt to the detection of the sag of the wire bundle 2 at different heights. By sleeved with a rotating part 395 on the mounting rod 391, the detection angle of the sensor 394 can be changed, so that the detection direction of the sensor 394 is changed, so that the detection mechanism 39 can be more adapted to the detection of the sag of different wire bundles 2, and the detection of the detection mechanism 39 can be more comprehensive and convenient. Preferably, two long through holes 3921 are provided on the mounting frame 392, and two mounting holes 3931 corresponding to the two long through holes 3921 are provided on the supporting frame 393, which can realize the vertical movement of the supporting frame 393 on the mounting frame 392, thereby changing the detection height of the sensor 394; the supporting frame 393 is installed on the mounting frame 392 by two bolts passing through the two long through holes 3921 and the two mounting holes 3931 in sequence, which can make the supporting frame 393 more stable when installed on the mounting frame 392, and the supporting frame 393 can move vertically along the long through holes 3921 to better detect the verticality of the filament bundle 2.

[0044] like Figure 1 As shown, reinforcing ribs are fixedly installed at the four corners of the top of the rack 1, which can make the rack 1 more stable and prevent the rack 1 from collapsing and being damaged due to the weight of the opening component 3 and the electric control box 5 and other equipment.

[0045] Through the above structure, the working principle of the device for opening and stabilizing the suction resistance of the cigarette filter tow 2 in this embodiment is as follows:

[0046] like Figure 1As shown, first assemble the device, then pull the tow 2 inside the frame 1 through the ring 4, place the tow 2 between the active roller 33 and the pressure roller 32 and pull it downward. Since the tow 2 itself has a certain weight, the tow 2 naturally sags, and the tow 2 is pulled upward along the multiple guide rollers 36 to other devices, and then drive the pushing mechanism 35, the extended end of the cylinder 351 extends, driving the pressure roller 32 to rotate around the axis of the second rotating shaft 354, thereby driving the pressure roller 32 to move toward the active roller 33, and then the pressure roller 32 gradually compresses the tow 2, and then the electric control box 5 drives the motor 34 to rotate, and at this time the motor 34 drives the active roller 33 to rotate, so as to gradually compress and loosen the tow 2. Since the tow 2 itself has a certain weight, the tow 2 naturally sags from the guide roller 36, and the detection mechanism 39 is used to detect the sag of the tow 2. According to the needs of the site and the sag standard of the yarn bundle 2, the sensor 394 is installed at a specific height through the mounting frame 392 and the supporting frame 393 to detect the sag of the yarn bundle 2; when the sag of the yarn bundle 2 is too low, the sensor 394 detects that the sag of the yarn bundle 2 is low, and the sensor 394 transmits the electrical signal of the low sag of the yarn bundle 2 to the electric control box 5, and the electric control box 5 immediately corrects the speed of the motor 34, that is, the motor 34 reduces the speed, thereby reducing the conveying speed of the yarn bundle 2, so as to reduce the conveying speed of the yarn bundle 2, thereby increasing the sag of the yarn bundle 2. When the sag of the tow 2 is too high, that is, when the sensor 394 cannot detect the tow 2, the sag of the tow 2 is too high, and the sensor 394 transmits the electrical signal of the high sag of the tow 2 to the electric control box 5, and the electric control box 5 immediately corrects the speed of the motor 34, that is, the motor 34 increases the speed, thereby increasing the conveying speed of the tow 2, and then reducing the sag of the tow 2, so that the sensor 394 can detect the tow 2 and reach the standard sag of the tow 2; when the sag of the tow 2 reaches the standard, the motor 34 will keep running at the current speed. In this way, the tow 2 can be fully compressed and loosened to avoid the breakage and flying of the tow 2.

[0047] The loosening and stabilizing device for cigarette filter tow of the present embodiment has a simple structure and a simple and quick operation method, and can effectively avoid broken and flying threads of the tow 2, making the fluctuation of the draw resistance and the standard value of the draw resistance more stable.
