Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a roving bobbin cleaning device. Background Technology
[0002] To achieve automatic yarn generation, roving frames used in spinning workshops currently require a certain degree of abrasiveness on the surface of the roving bobbin. However, after repeated use, residual fibers and blended foreign fibers often adhere to the surface of the bobbin. If not cleaned in time, this will seriously affect the quality of the next batch of yarn.
[0003] Currently, cleaning is generally done by manual scrubbing or electric rotary guns, which has problems such as high labor intensity, low cleaning efficiency, and sometimes difficulty in completely removing residual fibers, which is not conducive to on-site management.
[0004] There is an urgent need for a device that can automatically clean residual fibers from the surface of bobbins. Utility Model Content
[0005] To address the aforementioned technical shortcomings, this invention provides a roving bobbin cleaning device that enables automated cleaning of the bobbin surface with high efficiency.
[0006] This utility model discloses a roving bobbin cleaning device, including a frame, a single-row material trough at one end of the frame, the bottom plate of the single-row material trough being inclined, and an outlet on the side wall of the single-row material trough at the lowest point of the bottom plate, which outputs one bobbin at a time. A conversion trough is provided at the end of the single-row material trough, the bottom surface of the conversion trough being an inclined guide slope, the width of the guide slope accommodating only one bobbin, the guide slope being inclined along the length direction, and a downward outlet channel is provided at the lowest end of the guide slope, with a blocking mechanism provided at the outlet. A conveyor belt is provided on the frame below the outlet channel, and spindles are spaced apart on the conveyor belt. Several corresponding brush roller groups are provided on the frame on both sides of the conveyor belt, and the brush roller groups are used to clean the bobbins.
[0007] The structure of the blocking mechanism is as follows: a baffle is rotatably installed on the outer wall of a single-row material trough above the outlet via a pin, and a pushing cylinder is installed on the outer wall of a single-row material trough above the baffle via a pin. The extension and retraction end of the pushing cylinder is rotatably connected to the baffle via a pin.
[0008] Each brush roller assembly includes two brush rollers. The brush bristles of the brush rollers contact the tube on the conveyor belt between the brush rollers. The center-to-center distance between the two brush rollers in the same brush roller assembly is 30mm along the conveyor belt conveying direction. Each brush roller is driven to rotate by a power mechanism.
[0009] The brush roller assembly consists of three groups. In the group closest to the single-row trough, the two brush rollers behind the conveyor belt in the conveying direction have bristle diameters of 0.35-0.45 mm, while the brush roller in front of the conveyor belt in the conveying direction has bristle diameters of 0.25-0.3 mm. In the middle group, the two brush rollers behind the conveyor belt in the conveying direction have bristle diameters of 0.25-0.3 mm, while the brush roller in front of the conveyor belt in the conveying direction has bristle diameters of 0.20-0.25 mm. In the group furthest from the single-row trough, the two brush rollers behind the conveyor belt in the conveying direction have bristle diameters of 0.2-0.25 mm, while the brush roller in front of the conveyor belt in the conveying direction has bristle diameters of 0.15-0.2 mm.
[0010] A steel comb roller is installed on the frame between two adjacent brush rollers on the side of the conveyor belt. The steel comb teeth on the steel comb roller are 3-5cm long, and the ends of the steel comb teeth contact the ends of the brush bristles of the brush roller by 2-4mm. A power mechanism is installed on the frame, and the power mechanism drives the steel comb roller to rotate.
[0011] A dust collection hood is installed on the frame on the side of the conveyor belt, with the opening of the dust collection hood facing the conveyor belt. The brush roller and steel comb roller on the side of the conveyor belt are located inside the dust collection hood on the same side. A dust suction channel is installed on the frame below the dust collection hood, with a suction fan installed at the end of the dust suction channel. A lint collection box is installed on the dust suction channel, and a dust collection bag or filter screen is installed inside the lint collection box.
[0012] The roving bobbin cleaning device obtained by this utility model can realize automatic feeding of bobbins to the spindles on the conveyor belt, and at the same time use the brush roller group for automatic cleaning.

Detailed Implementation
[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0015] Example 1: like Figures 1-5 As shown, this utility model discloses a roving bobbin cleaning device, including a frame 1. A single-row material trough 2 is provided at one end of the frame 1. The bottom plate of the single-row material trough 2 is inclined. An outlet 11 is provided on the side wall of the single-row material trough 2 at the lowest point of the bottom plate. The outlet 11 outputs one bobbin 8 at a time. A conversion trough 3 is provided at the end of the single-row material trough 2. The bottom surface of the conversion trough 3 is an inclined guide slope. The width direction of the guide slope can only accommodate one bobbin 8. The guide slope is inclined along the length direction. A downward outlet channel 4 is provided at the lowest end of the guide slope. A blocking mechanism is provided at the outlet 11. A conveyor belt 5 is provided on the frame 1 below the outlet channel 4. Insert spindles 6 are arranged at intervals on the conveyor belt 5. Several corresponding brush roller groups are provided on the frame 1 on both sides of the conveyor belt 5. The brush roller groups are used to clean the bobbins 8.
[0016] The single-row material trough 2 can accommodate horizontally placed cylindrical tubes 8. The width of the single-row material trough 2 is the same as or slightly larger than the length of the cylindrical tubes 8. The operator only needs to arrange the cylindrical tubes 8 horizontally within the single-row material trough 2. Because the bottom plate of the single-row material trough 2 is inclined, under the pressure of gravity, the cylindrical tubes 8 at the lowest point of the bottom plate of the single-row material trough 2 will be horizontally output from the outlet 11 into the conversion trough 3. The length of the outlet 11 covers the entire width of the single-row material trough 2, and its width is slightly larger than the diameter of the cylindrical tubes 8, so one cylindrical tube 8 can be output at a time. After entering the conversion trough 3, the size of the conversion trough 3 can only accommodate one cylindrical tube 8. Of course, to prevent the cylindrical tubes 8 in the single-row material trough 2 from being squeezed by the cylindrical tubes 8 in the conversion trough 3 at the outlet 11, a blocking mechanism needs to be installed at the outlet 11. The blocking mechanism can control the timed output of the cylindrical tubes 8 in the single-row material trough 2. Because the bottom of the conversion trough 3 is an inclined guide slope, the bobbin 8 inside the conversion trough 8 tilts under the action of gravity. The slope of the guide slope can be 45° or even greater, causing the bobbin 8 to tilt and stand upright, eventually being output outward from the outlet channel 4. When the bobbin 8 is output outward from the outlet channel 4, the insert 6 on the output end below the outlet channel 4 corresponds to the outlet channel 4, and the bobbin 8 is fitted onto the insert 6, realizing the automatic assembly of the bobbin 8 on the conveyor belt 5, which greatly improves the assembly efficiency and makes the cleaning of the bobbin 8 more efficient and stable.
[0017] The bobbin 8, which is inserted into the spindle 6, moves forward with the conveyor belt 5. During the movement, the brush rollers on the frame 1 on both sides of the conveyor belt 5 clean the bobbin 8, removing the fibers from its surface, thus revealing the abrasive characteristics of the bobbin 8 surface. This provides a basis for the automatic yarn generation of the subsequent roving frame and ensures the quality of the yarn.
[0018] In practice, the bottom plate of the single-row material trough 2 is inclined at 20°, with an internal width of about 320mm, a height of 1200-1400mm, and a length of about 1500mm. In this way, the entire single-row material trough 2 can accommodate 200-300 cylinders 8.
[0019] The structure of the blocking mechanism is as follows: a baffle 12 is rotatably mounted on the outer wall of the single-row material trough 2 above the outlet 11 via a pin shaft, and a push cylinder 13 is mounted on the outer wall of the single-row material trough 2 above the baffle 12 via a pin shaft. The telescopic end of the push cylinder 13 is rotatably connected to the baffle 12 via a pin shaft.
[0020] The blocking mechanism can take various forms, as long as it can controllably block the outlet 11. This embodiment uses one form, such as a baffle 12. The baffle 12 is rotatably connected to the outer wall of the single-row material trough 2 above the outlet 11 via a pin. That is, when the baffle 12 rotates upward, it can be completely positioned above the outlet 11, and when the baffle 12 rotates downward, it can be partially positioned within the range of the outlet 11, thus blocking the cylinder 8 at the outlet 11. Moreover, since the baffle 12 is located on the outside, it will not be squeezed by the cylinder 8 inside the single-row material trough 2, making the opening and closing more stable and reliable. A push cylinder 13 is set on the outer wall of the single-row material trough 2. The push cylinder 13 drives the baffle 12 to rotate, thereby enabling the baffle 12 to block or not block the outlet 11. Of course, the entire device has a controller, and the push cylinder 13 is controlled by the controller to ensure its coordination with the operation of the conveyor belt 5.
[0021] Each brush roller group includes two brush rollers 9, the bristles of the brush rollers 9 contact the tube 8 on the conveyor belt 5 between the brush rollers 9, the center of the two brush rollers 9 in the same brush roller group is 30mm apart along the conveying direction of the conveyor belt 5; each brush roller 9 is driven to rotate by a power mechanism.
[0022] Since the outer diameter of the bobbin 8 is fixed, the distance between the brush rollers 9 and the insert spindle 6 can be controlled according to actual needs to ensure that the bristles of the brush rollers 9 contact the bobbin 8 on the insert spindle 6. The two brush rollers 9 in each brush roller group are staggered front to back by about 30mm, which allows for better cleaning of the bobbin 8, achieving two efficient cleaning cycles and improving the cleaning effect. The power mechanism can be an electric motor.
[0023] There are three sets of brush rollers. The two brush rollers 9 in the set closest to the single-row trough 2 have a bristle diameter of 0.4 mm behind the conveyor belt 5 in the conveying direction, and a bristle diameter of 0.3 mm in front of the conveyor belt 5 in the conveying direction. The two brush rollers 9 in the middle set have a bristle diameter of 0.28 mm behind the conveyor belt 5 in the conveying direction, and a bristle diameter of 0.23 mm in front of the conveyor belt 5 in the conveying direction. The two brush rollers 9 in the set furthest from the single-row trough 2 have a bristle diameter of 0.2 mm behind the conveyor belt 5 in the conveying direction, and a bristle diameter of 0.15 mm in front of the conveyor belt 5 in the conveying direction.
[0024] The bristle diameter of each brush roller 9 in the three sets of brush rollers is appropriately set, that is, the brush roller 9 that first contacts the bobbin 8 has the largest bristle diameter, and then decreases in size, with the brush roller 9 that last contacts the bobbin 8 having the smallest bristle diameter. In this way, while maintaining a good and stable fiber removal ability on the surface of the bobbin 8 during the actual brushing process, damage to the surface of the bobbin 8 can be effectively reduced. In particular, at the end, after the fibers on the surface of the bobbin 8 have been removed, the removal of some short fibers can be achieved through the fine bristles without damaging the wear and tear characteristics of the surface of the bobbin 8.
[0025] A steel comb roller 10 is installed on the frame 1 between two adjacent brush rollers 9 on the side of the conveyor belt 5. The steel comb teeth on the steel comb roller 10 are 3-5 cm long, and the ends of the steel comb teeth contact the ends of the brush bristles of the brush roller 9 for 2-4 mm. A power mechanism is installed on the frame 1, which drives the steel comb roller 10 to rotate. Since the fibers brushed off the bobbin 8 by the brush roller 9 will adhere to the surface of the brush roller 9, to avoid fiber accumulation on the brush roller 9, a steel comb roller 10 is installed on the frame 1 on its side. The teeth of the steel comb roller 10 are sparsely spaced, and the steel comb teeth of the steel comb roller 10 only contact the ends of the brush bristles, transferring the fibers on the surface of the brush bristles to the steel comb teeth. The power mechanism is an electric motor.
[0026] A dust collection hood 7 is provided on the frame 1 on the side of the conveyor belt 5. The opening of the dust collection hood 7 faces the conveyor belt 5. The brush roller 9 and the steel comb roller 10 on the side of the conveyor belt 5 are both located inside the dust collection hood 7 on the same side. A dust suction channel is provided on the frame 1 below the dust collection hood 7. A suction fan is provided at the end of the dust suction channel. A lint collection box is provided on the dust suction channel. A dust collection bag or filter screen is provided inside the lint collection box.
[0027] When the fibers are transferred to the steel comb teeth, a negative pressure zone is created under the action of the dust collection hood 7 and the suction fan, thereby forming an airflow. The fibers on the steel comb teeth are adsorbed and enter the dust collection bag or filter screen of the lint collection box through the dust collection channel for fiber collection. The lint collection box can be fixed to the dust collection channel in a drawer-like manner, making it convenient to replace and clean the dust collection bag, filter screen, etc.
[0028] The conveyor belt 5 is controlled by a servo motor, which in turn is controlled by a controller. When the insert 6 on the conveyor belt 5 reaches below the outlet channel 4, it stops and waits for the bobbin 8 to fall. When the insert 6 reaches its position, the push cylinder 13 retracts, lifting the baffle 12. A bobbin 8 then enters the conversion groove 3 from the outlet 11. At this time, the baffle 12 moves down to block it, and the bobbin 8 in the conversion groove 3 adjusts its direction and exits from the outlet channel 4, inserting itself onto the insert 6, thus achieving automatic installation. Then the conveyor belt 5 continues to move forward, repeating the above process.
[0029] Of course, depending on actual needs, the spacing between the closest brush roller groups of the inserts 6 at the outlet channel 4 can be one or several times the spacing between two adjacent inserts 6. The spacing between adjacent brush roller groups is one or several times the spacing between two adjacent inserts 6. Meanwhile, the spacing of the inserts 6 on the conveyor belt 5 is the same.
[0030] In this way, while waiting for the bobbin 8 to be inserted into the insert 6 on the conveyor belt 5, the bobbin 8 on the conveyor belt 5 can be brushed between the corresponding brush roller groups, thereby improving the cleaning efficiency.
