Technical Field

[0001] This application relates to the field of frame unwinding machines, and more particularly to a frame unwinding machine with a cleaning device. Background Technology

[0002] Fabric unwinding machines are devices used in the textile industry to unwind rolls of fabric for subsequent inspection or processing.

[0003] In related technologies, please refer to the invention patent with publication number CN102862842A, which discloses an unwinding machine, including a base, a vertical support on the base, and a horizontal support on the vertical support. The front end of the horizontal support is provided with an unwinding frame, the bottom of the unwinding frame is provided with an unwinding rotating shaft, the horizontal support is provided with an unwinding frame drive mechanism, and the base is provided with a fabric roll frame. In use, the fabric roll is placed on the fabric roll frame, a portion of the fabric roll is pulled out and staggered and wound around the limiting roller, and then wound around the unwinding rotating shaft. The motor is started, and the rotating wheel drives the first connecting rod to rotate, and then the second connecting rod pushes the unwinding frame to swing, pulling the fabric roll and realizing the effective unwinding of the fabric roll.

[0004] When fabric is unwound, lint often adheres to the fabric due to the fabric itself, the production process, and the environment. Using the fabric directly without removing the lint will affect subsequent processes and thus the quality of the fabric. Utility Model Content

[0005] To address the problem of lint on fabric affecting subsequent processes and fabric quality, this application provides a frame unwinding machine with a cleaning device.

[0006] The frame unwinding machine with a cleaning device provided in this application adopts the following technical solution: A frame unwinding machine with a cleaning device includes a frame, a fabric feeding trough on the frame, a plurality of parallel guide rollers on the frame and above the fabric feeding trough, a fabric swaying mechanism on one side of the frame, and a cleaning assembly on the frame and on one side of the guide rollers. The cleaning assembly includes a collection hood and a negative pressure mechanism. Two collection hoods are provided and distributed opposite each other on both sides of the fabric. The negative pressure mechanism is located on the frame and connected to the collection hoods, and is used to provide negative pressure to the collection hoods.

[0007] By adopting the above technical solution, the fabric is conveyed by the guide roller, passes through the collection hood, and is then arranged by the fabric arranging mechanism. The negative pressure mechanism provides negative pressure to the collection hood, and the two collection hoods, which are distributed on both sides of the fabric, simultaneously adsorb lint from both sides of the fabric, thoroughly cleaning the fabric, effectively reducing lint residue on the fabric surface, avoiding interference from lint to subsequent processing steps, and ensuring the quality of the fabric.

[0008] Optionally, the negative pressure mechanism includes an air pump, a filter box, and an air duct. The air duct is connected to the collection cover, the filter box is mounted on the frame, and the end of the air duct facing away from the collection cover is connected to the filter box. The air pump is mounted on the side of the filter box facing away from the air duct, and the filter box contains a filter plate for filtering lint.

[0009] By adopting the above technical solution, the air pump creates negative pressure inside the collection hood through the air duct. The adsorbed lint will enter the filter box through the air duct with the airflow. The filter plate inside the filter box intercepts and filters the lint, and the treatment effect of lint and other debris is good.

[0010] Optionally, a cleaning brush is provided inside the collection hood, the cleaning brush is distributed along the length of the collection hood, the cleaning brush has bristles on the side facing the fabric, and an elastic element for elastically pressing the fabric is provided inside the collection hood.

[0011] By adopting the above technical solution, the bristles of the cleaning brush come into contact with the fabric surface. During the fabric conveying process, the bristles sweep away the lint adhering to the fabric surface. Combined with the negative pressure adsorption of the collection hood, the lint cleaning effect is improved. The elastic element pushes the cleaning brush to press against the fabric elastically, adapting to fabrics of different thicknesses. At the same time, the elastic pressing reduces the probability of damaging the fabric.

[0012] Optionally, the elastic element includes a guide rod and a spring, and an installation block is provided on the inner side wall of the collection cover. The guide rod is connected to the cleaning brush and is slidably connected to the installation block. The spring is sleeved on the guide rod and connected to the installation block, and the end of the spring away from the installation block is connected to the cleaning brush.

[0013] By adopting the above technical solution, the cloth pusher rod slides along the mounting block. At this time, the elastic force of the spring continuously pushes the cleaning brush to press against the cloth, ensuring the cleaning effect and reducing excessive compression damage to the cloth.

[0014] Optionally, a beating roller is rotatably installed inside the collection hood, the radial cross-sectional shape of the beating roller is elliptical, and a driving component for driving the beating roller to rotate is provided on the frame.

[0015] By adopting the above technical solution, when the driving component drives the elliptical cross-section beating roller to rotate, the protruding part of the outer peripheral wall of the beating roller periodically beats the fabric surface, knocking off the lint in the gaps between the fabric fibers, thereby further improving the lint cleaning effect.

[0016] Optionally, the driving component includes a gear, a rack, and a driving cylinder. The gear is coaxially connected to the beating roller, the rack is slidably mounted on the frame, and the gear meshes with the rack. The driving cylinder is mounted on the frame, and the rack is connected to one end of the piston rod of the driving cylinder.

[0017] By adopting the above technical solution, the piston rod of the drive cylinder extends and retracts, causing the rack to slide along the frame. The rack meshes with the gear, which in turn drives the beater roller, which is coaxially connected to the gear, to rotate back and forth. The drive is stable and has a good effect.

[0018] Optionally, the racks on the upper and lower sides are connected to each other and distributed downwards relative to each other, and a push block is provided at one end of the piston rod of the drive cylinder, the push block being connected to the rack.

[0019] By adopting the above technical solution, a single drive cylinder simultaneously drives the upper and lower racks to slide synchronously, thereby driving the upper and lower beaters to rotate synchronously, reducing the number of drive components and lowering the equipment manufacturing cost and energy consumption.

[0020] Optionally, the sizing mechanism includes a sizing plate and a sizing rod. The sizing plate is rotatably mounted on the frame. The frame is equipped with a sizing motor for driving the sizing plate to rotate. A connecting rod is rotatably mounted on the frame. The sizing plate is used to drive the connecting rod to reciprocate. The sizing rod is connected to one end of the connecting rod.

[0021] By adopting the above technical solution, the swaying motor drives the swaying disk to rotate, the swaying disk drives the connecting rod to rotate back and forth around the frame, and in turn drives the swaying rod to swing back and forth, thereby improving the unwinding efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A collection hood simultaneously absorbs lint from both sides of the fabric, thoroughly cleaning the fabric, reducing lint residue on the fabric surface, avoiding interference with subsequent processing steps, and ensuring fabric quality. 2. The filter plates inside the filter box intercept and filter the adsorbed hair and lint, and have a good effect on treating hair and other impurities; 3. The brush bristles sweep away lint from the fabric surface, and the negative pressure adsorption of the collection cover improves the lint removal effect. The elastic element pushes the cleaning brush to press firmly, adapting to fabrics of different thicknesses and reducing the probability of fabric damage. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a frame unwinding machine with a cleaning device, referring to... Figure 1 The system includes a frame 1, a fabric feeding trough 11, a fabric guide roller 12, a fabric swaying mechanism 2, and a cleaning component. The fabric feeding trough 11 is located at the bottom of the frame 1 and is used to hold the fabric roll. Several parallel fabric guide rollers 12 are arranged on the frame 1 and located above the fabric feeding trough 11. The fabric swaying mechanism 2 is located on one side of the frame 1. The cleaning component is located on the frame 1 and on one side of the fabric guide rollers 12. The cleaning component includes a collection hood 3 and a negative pressure mechanism 4. Two collection hoods 3 are arranged opposite each other on the upper and lower sides of the fabric. The two collection hoods 3 are arranged opposite each other and simultaneously adsorb lint from both sides of the fabric. The negative pressure mechanism 4 is arranged on the frame 1 and connected to the collection hoods 3. The negative pressure mechanism 4 is used to provide negative pressure to the collection hoods 3. The fabric is conveyed by the guide roller 12, passes through the cleaning component, and is then arranged by the fabric arranging mechanism 2. The negative pressure mechanism 4 provides negative pressure to the collection hood 3. The two collection hoods 3, which are distributed on both sides of the fabric, simultaneously adsorb lint from both sides of the fabric, thoroughly cleaning the fabric and effectively reducing lint residue on the fabric surface.

[0031] Reference Figure 1The negative pressure mechanism 4 includes an air pump 41, a filter box 42, and an air duct 43. One end of the air duct 43 is connected to the inside of the collection hood 3, and both the upper and lower sides of the collection hood 3 are connected to the air duct 43. The filter box 42 is located on one side of the frame 1, and the end of the air duct 43 facing away from the collection hood 3 is connected to the filter box 42. The air pump 41 is located on the side of the filter box 42 facing away from the air duct 43 and is connected to the inside of the filter box 42. The filter box 42 is equipped with a filter plate for filtering hair. The air pump 41 creates a negative pressure inside the collection hood 3 through the air duct 43. The adsorbed hair will enter the filter box 42 with the airflow through the air duct 43. The filter plate inside the filter box 42 intercepts and filters the hair.

[0032] Reference Figure 2 and Figure 3 The collection cover 3 is also equipped with a cleaning brush 44 and an elastic element 45. The cleaning brush 44 is distributed along the length of the collection cover 3, and bristles 441 are provided on the side of the cleaning brush 44 facing the fabric. The elastic element 45 is used to elastically press against the fabric. The elastic element 45 includes a guide rod 451 and a spring 452. A horizontal mounting block 31 is provided on the inner wall of the collection cover 3. The guide rod 451 is connected to the side of the cleaning brush 44 away from the bristles 441. The guide rod 451 is vertically slidably connected to the mounting block 31. The spring 452 is sleeved on the guide rod 451 and connected to the mounting block 31. The end of the spring 452 away from the mounting block 31 is connected to the cleaning brush 44. When the fabric pushes the guide rod 451 to slide along the mounting block 31, the elastic force of the spring 452 continuously pushes the cleaning brush 44 to press against the fabric, ensuring the cleaning effect while reducing excessive compression damage to the fabric. The bristles 441 of the cleaning brush 44 come into contact with the fabric surface. During the fabric conveying process, the bristles 441 sweep away the lint attached to the fabric surface. Combined with the negative pressure adsorption of the collection cover 3, the lint cleaning effect is improved. The elastic element 45 pushes the cleaning brush 44 to elastically press against the fabric, adapting to fabrics of different thicknesses. At the same time, the elastic pressing reduces the probability of damaging the fabric.

[0033] Reference Figure 2 and Figure 3A beating roller 32 is rotatably mounted inside the collection hood 3, and a driving component 5 for driving the beating roller 32 to rotate is provided on the frame 1. The beating roller 32 is distributed along the length of the collection hood 3, and the radial cross-section of the beating roller 32 is elliptical. The beating roller 32 is rotatably connected to the frame 1 via a rotating shaft. The driving component 5 includes a gear 51, a rack 52, and a driving cylinder 53. The gear 51 is coaxially and fixedly connected to the rotating shaft of the beating roller 32. The rack 52 is slidably mounted on the frame 1, and the gear 51 meshes with the rack 52. The driving cylinder 53 is located on the frame 1, and one end of the rack 52 is connected to the piston rod of the driving cylinder 53. The extension and retraction of the piston rod of the driving cylinder 53 drives the rack 52 to slide along the frame 1. The rack 52 meshes with the gear 51, thereby driving the beating roller 32, which is coaxially connected to the gear 51, to rotate reciprocally. The driving is stable and effective. The upper and lower racks 52 are interconnected and distributed downwards relative to each other. A push block is provided at one end of the piston rod of the drive cylinder 53, and the push block is connected to the rack 52. A single drive cylinder 53 simultaneously drives the upper and lower racks 52 to slide synchronously, thereby driving the upper and lower beating rollers 32 to rotate synchronously. This reduces the number of drive components and lowers equipment manufacturing costs and energy consumption. When the drive component 5 drives the elliptical cross-section beating roller 32 to rotate, the protruding part of the outer peripheral wall of the beating roller 32 periodically beats the fabric surface, knocking down lint from the fabric fiber gaps, further improving the lint removal effect.

[0034] Reference Figure 2 and Figure 4 The swaying mechanism 2 includes a swaying disc 21 and a swaying rod 22. The swaying disc 21 is rotatably mounted on a frame 1. A swaying motor 23 is mounted on the frame 1. A first pulley 24 is coaxially mounted on the output shaft of the swaying motor 23. A second pulley 25 is mounted on the frame 1. A synchronous belt 26 is fitted on the first pulley 24 and the second pulley 25. The second pulley 25 is coaxially connected to the swaying disc 21. A connecting rod 27 is rotatably mounted on the frame 1. A rotation limit rod 28 is eccentrically mounted on the swaying disc 21. A guide hole 271 is opened on the connecting rod 27. The limit rod 28 is slidably connected to the guide hole 271. Both ends of the swaying rod 22 are connected to the end of the connecting rod 27 that is away from the rotation axis of the connecting rod 27. The swaying motor 23 drives the swaying disk 21 to rotate, the swaying disk 21 drives the limit rod 28 to rotate, the limit rod 28 pushes the connecting rod 27 to rotate through the guide hole 271, causing the connecting rod 27 to reciprocate around the frame 1, which in turn drives the swaying rod 22 to reciprocate, thereby improving the unwinding efficiency.

[0035] The implementation principle of a frame unwinding machine with a cleaning device in this application embodiment is as follows: The fabric roll is placed in the fabric feeding trough 11 and conveyed by the guide roller 12. When the fabric passes through the cleaning component, the negative pressure mechanism 4 is activated, and the suction pump 41 creates a negative pressure inside the collection hood 3 through the air duct 43. The suction pump 41 generates suction, which draws out the air inside the collection hood 3 through the air duct 43. The adsorbed lint will enter the filter box 42 with the airflow through the air duct 43. The filter plate inside the filter box 42 intercepts and filters the lint. The cleaning brush 44 inside the collection hood 3 presses against the fabric, and the fabric pushes the guide rod 451 to slide along the mounting block 31. The elastic force of the spring 452 continuously pushes the cleaning brush 44 against the fabric. The bristles 441 of the cleaning brush 44 contact the surface of the fabric, and during the fabric conveying process, the bristles 441 clean the lint attached to the surface of the fabric.

[0036] The piston rod of the drive cylinder 53 extends and retracts, causing the rack 52 to slide along the frame 1. The rack 52 meshes with the gear 51, which in turn drives the beating roller 32, which is coaxially connected to the gear 51, to rotate reciprocally. The protruding part of the outer peripheral wall of the beating roller 32 periodically beats the surface of the fabric, knocking off the lint from the gaps in the fabric fibers.

[0037] After cleaning, the fabric arrives at the spreading mechanism 2. The spreading motor 23 drives the spreading disc 21 to rotate, and the spreading disc 21 drives the connecting rod 27 to rotate back and forth around the frame 1, which in turn drives the spreading rod 22 to swing back and forth, spreading the fabric.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
