Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more particularly to a roller cleaning device. Background Technology

[0002] Textile rollers are an important component of textile machinery, primarily used to transfer and distribute yarn during the spinning process. Rollers are typically made of rubber, plastic, or other soft materials, possessing a certain degree of elasticity and wear resistance. They function in various parts of textile machinery, such as carding machines, drawing frames, roving frames, and spinning frames, for stretching, shaping, and transferring yarn. Over time, textile rollers accumulate dirt due to yarn, oil, dust, and other contaminants, affecting their normal transfer and distribution functions. Therefore, regular surface cleaning of textile rollers is crucial.

[0003] In the existing technology, the cleaning of the rollers is carried out by stopping the machine for cleaning. However, the above method delays the production progress and cannot clean the dirt accumulated on the rollers in a timely manner during the production process. Therefore, a scraper can be set up to contact the roller and clean its surface in a timely manner by the rotation of the roller. However, the above method still has the problem that the scraped dirt will accumulate on the surface of the scraper. If it is not cleaned for a long time, it will lead to the opposite effect. There is room for improvement. Therefore, a roller cleaning device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a roller cleaning device that enables rapid and efficient cleaning of rollers and reduces the frequency of roller entanglement.

A limiting rotating groove corresponding to the connecting chuck is also provided on the side wall of the rotating groove. The trigger push rod is set in the connecting groove. One end of the trigger push rod located inside the connecting groove is equipped with a trigger. The trigger is used to contact the limit seat, drive the trigger push rod to run and engage with the connecting chuck on the telescopic disc through its output end, and push the telescopic disc to retract, so that the connecting pin is disengaged from the reciprocating screw, thereby driving the cleaning scraper to run and contact the leather roller. The trigger push rod is also equipped with a control unit and a timing unit. The control unit is used to periodically drive the trigger push rod to retract. The telescopic column and the contact spring are located inside the connecting plate. The contact spring is used to push the telescopic plate and the connecting pin on it to re-engage with the reciprocating screw and drive the reciprocating screw to run when the trigger push rod retracts.

[0006] Furthermore, the limiting seat is provided with a traction spring and a limiting arc groove. The limiting seat is rotatably connected to the tilting arm. The tilting arm is provided with a traction shaft that is fixedly connected to the traction spring and passes through the limiting arc groove. The traction spring is used to pull the traction shaft to deflect it to one side of the limiting arc groove, so that the tilting arm tilts and fits against the surface of the sliding scraper.

[0007] Furthermore, the limiting seat is provided with a traction spring and a limiting arc groove. The limiting seat is rotatably connected to the tilting arm. The tilting arm is provided with a traction shaft that is fixedly connected to the traction spring and passes through the limiting arc groove. The traction spring is used to pull the traction shaft to deflect it to one side of the limiting arc groove, so that the tilting arm tilts and fits against the surface of the sliding scraper.

[0008] Furthermore, the cleaning scraper is provided with movable abutments on both sides, which are used to contact the tilting arm to scrape off the dirt accumulated on the tilting arm and push the tilting arm to tilt to the other side.

[0012] Furthermore, the width of the transmission part is greater than the length of the cleaning scraper; The transmission part is rotatably connected to the support frame, and a connecting hole is provided on the side of the transmission part away from the support frame, so that the reciprocating lead screw can be installed inside the transmission part.

[0013] The beneficial effects of this invention are reflected in: This invention cleans dirt and impurities from the surface of a roller using a cleaning scraper. It also proposes a sliding scraper that fits into the cleaning scraper. The sliding scraper is connected to a reciprocating screw drive. When the reciprocating screw rotates, it drives the sliding scraper to reciprocate on the cleaning scraper, thereby cleaning the dirt accumulated at the connection between the cleaning scraper and the roller. As the sliding scraper slides, it can be deflected to the other side by a movable abutment when it moves to one side of the cleaning scraper. The movable abutment, in addition to changing the rotation direction of the tilting arm, can also be used to detach the dirt cleaned from the tilting arm for easy collection.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7 The present invention discloses a roller cleaning device, comprising: Roller 01; The cleaning scraper 1 is in contact with the roller 01. The cleaning scraper 1 is used to scrape off dirt from the surface of the roller. It should be noted that the cleaning scraper 1 can be inclined along the rotation direction of the roller 01 to avoid the scraped dirt from accumulating at the connection between the roller 01 and the cleaning scraper 1. A support frame 2 for supporting the cleaning scraper 1 is provided at one end of the cleaning scraper 1; A sliding scraper 3 is disposed on the surface of the cleaning scraper 1, and the sliding scraper 3 is used to move left and right to remove dirt accumulated on the surface of the cleaning scraper 1; The cleaning scraper 1 is provided with a transmission part 11 at the end away from the roller 01. A reciprocating screw 5 is rotatably provided in the transmission part 11. The reciprocating screw 5 is provided with a sliding groove. It should be noted that the sliding groove on the reciprocating screw 5 is a thread with opposite ends and interlacing threads. The reciprocating screw 5 is a common technical means in the prior art, so its specific parameters and structure are not described in detail. The sliding scraper 3 includes a sliding column 31 adapted to the sliding groove, a limiting seat 32, and an inclined swing arm 33 that fits against the sliding scraper 3. The reciprocating screw 5 rotates to drive the sliding scraper 3 to reciprocate along the surface of the cleaning scraper 1 through the sliding column 31, thereby cleaning the surface of the cleaning scraper 1.

[0018] In use, this application cleans the dirt and impurities on the surface of the roller 01 by cleaning scraper 1. In order to clean the dirt accumulated on cleaning scraper 1 and prevent it from accumulating at the connection between cleaning scraper 1 and roller 01 and affecting the subsequent cleaning effect, a sliding scraper 3 that fits with cleaning scraper 1 is proposed. The sliding scraper 3 is connected to the reciprocating screw 5 for transmission. When the reciprocating screw 5 rotates, it can drive the sliding scraper 3 to reciprocate on cleaning scraper 1, thereby cleaning the dirt on cleaning scraper 1.

[0019] It should be noted that, in order to make the sliding scraper 3 tilted on the cleaning scraper 1 and better guide the dirt to the side away from the roller 01, the limiting seat 32 is provided with a traction spring 34 and a limiting arc groove 35. The limiting seat 32 is rotatably connected to the tilting arm 33, and the tilting arm 33 is provided with a traction shaft 36 that is fixedly connected to the traction spring 34 and passes through the limiting arc groove 35. The traction spring 34 is used to pull the traction shaft 36 to deflect the traction shaft 36 to one side of the limiting arc groove 35, so that the tilting arm 33 is tilted and attached to the surface of the sliding scraper 3.

[0020] Furthermore, the cleaning scraper 1 is provided with movable abutment rods 4 on both sides. The movable abutment rods 4 are used to contact the tilting arm 33 to scrape off the dirt accumulated on the tilting arm 33 and push the tilting arm 33 to tilt to the other side.

[0021] With the above structural configuration, when the sliding scraper 3 slides, it can be deflected to the other side by the movable abutment 4 when it moves to one side of the cleaning scraper 1. During the deflection of the sliding scraper 3, the traction spring 34 can pull the tilting arm 33 and the traction shaft 36 to the other side and make the traction shaft 36 engage with the other end of the limiting arc groove 35.

[0022] It should be noted that the tilting direction of the tilting arm 33 is consistent with its moving direction, and the pulling force of the traction spring 34 is greater than the friction between the tilting arm 33 and the cleaning scraper 1, so as to prevent the tilting arm 33 from swinging when the cleaning scraper 1 moves, thus failing to collect dirt.

[0023] Furthermore, the movable abutment 4 includes sliding grooves 44 formed on both sides of the sliding scraper 3. A limiting rod 41 is provided in the sliding groove 44. A moving block 42 is sleeved on the limiting rod 41. A contact scraper 45 extending to the front of the sliding scraper 3 is provided on the moving block 42. A return spring 43 that abuts against the moving block 42 is also sleeved on the limiting rod 41. The return spring 43 is used to keep the contact scraper 45 at the top of the tilting arm 33 until it contacts the arm for complete scraping.

[0024] In the above structure, the movable stop bar 4 is used not only to change the rotation direction of the tilting arm 33, but also to remove the dirt cleaned off the tilting arm 33 and make it easier to collect.

[0025] Specifically, through the setting of the return spring 43, the return spring 43 contacts the moving block 42, and the moving block 42 is fixedly connected to the contact scraper 45. When the tilting arm 33 contacts the contact scraper 45 at the first moment, since the tilting arm 33 is in a tilted state, it can press down on the contact scraper 45 when it continues to move, so that the contact scraper 45 moves downward along the tilting arm 33, thereby achieving the purpose of removing dirt from the tilting arm 33. Until the moving block 42 moves to the lowest position, the tilting arm 33 continues to move horizontally. At this time, the contact scraper 45 is resisted and relatively fixed, while the tilting arm 33 deflects under the action of the traction spring 34. After the tilting arm 33 deflects, it disengages from the contact scraper 45. At this time, the contact scraper 45 returns to its original position and rises under the action of the return spring 43, waiting for the next contact with the tilting arm 33. Under the action of the reciprocating screw 5, the above process is repeated, thereby achieving the purpose of efficient cleaning and preventing dirt accumulation.

[0026] In this application, it is easy to imagine that the transmission part 11 of the cleaning scraper 1 is provided with a connecting groove, and the sliding scraper 3 extends into the transmission part 11 through the connecting groove and is connected to the reciprocating screw 5 for transmission. The connecting groove and the limiting seat 32 are provided with mutually meshing limiting ribs 322 and limiting grooves 321.

[0027] Furthermore, a transmission assembly 6 is provided between the roller 01 and the reciprocating screw 5. The transmission assembly 6 includes a pulley 61 on the roller 01 and a driven wheel 62 that is connected to the reciprocating screw 5. The driven wheel 62 and the pulley 61 are connected by a transmission belt so that the reciprocating screw 5 can rotate synchronously with the roller 01. It should be noted that the diameter of the driven wheel 62 is larger than the diameter of the pulley 61. Under the drive of the transmission assembly 6, the cleaning scraper 1 rotates in the same direction as the roller 01. When the cleaning scraper 1 rotates, it can approach the roller 01 and until it is in contact with it.

[0028] It is easy to imagine that the roller 01 is mounted on the mounting base 8, and the mounting base 8 is provided with a plurality of collection boxes 81 located below the movable abutment 4 for collecting fallen dirt. In this application, a transmission structure corresponding to the roller 01 should also be provided to provide power to the roller so that it can rotate for easy cleaning, or to realize the transportation of yarn.

[0029] like Figure 4 As shown, the width of the transmission part 11 is greater than the length of the cleaning scraper 1, and the length of the reciprocating screw 5 is also greater than the length of the cleaning scraper 1. At the same time, the length of the cleaning scraper 1 is also greater than the length of the rubber roller 01, which facilitates the thorough cleaning of dirt from the rubber roller 01. The transmission part 11 is rotatably connected to the support frame 2. A connecting hole is provided on the side of the transmission part 11 away from the support frame 2. The connecting hole allows the reciprocating screw 5 to be placed inside the transmission part 11. That is, one side of the cleaning scraper 1 is fixedly set by the support frame 2, and the reciprocating screw 5 rotates synchronously with the roller 01. The reciprocating screw 5 extends from the other side of the cleaning scraper 1 into its interior, driving the sliding scraper 3 to clean.

[0030] Another embodiment that needs to be described in this application is as follows, please refer to... Figure 4 , 8 -12, The driven wheel 62 is provided with a power distribution component 7, which is used to drive the cleaning scraper 1 to contact the leather roller 01 or to drive the reciprocating screw 5 to rotate. The power distribution assembly 7 includes a connecting plate 75, a telescopic plate 71 disposed within the connecting plate 75, a trigger push rod 72, a telescopic column 73, and a resisting spring 74. The telescopic disc 71 is movably provided with a connecting chuck 711, and a connecting pin 712 is provided in the center of the telescopic disc 71, which passes through the connecting chuck 711. The reciprocating screw 5 is provided with a transmission hole corresponding to the connecting pin 712. The telescopic disc 71 has a rotating groove corresponding to the connecting chuck 711. A reset torsion spring 7111 fixedly connected to the connecting chuck 711 is provided in the rotating groove. A limiting rotating groove 7112 corresponding to the connecting chuck 711 is also provided on the side wall of the rotating groove. It should be noted that the elastic force required for the torsion of the reset torsion spring 7111 is greater than the weight of the cleaning scraper 1. The limiting rotating groove 7112 is provided so that the connecting chuck 711 can be rotated while being pushed by the trigger push rod 72, which allows the telescopic disc 71 to retract. The trigger push rod 72 is disposed in the connecting slide groove. One end of the trigger push rod 72 located inside the connecting slide groove is provided with a trigger. The trigger is used to contact the limiting seat 32, drive the trigger push rod 72 to run through its output end to engage with the connecting chuck 711 on the telescopic disc 71, and push the telescopic disc 71 to retract, so that the connecting pin 712 is disengaged from the reciprocating screw 5, thereby driving the cleaning scraper 1 to run and contact the leather roller 01. The trigger push rod 72 is also equipped with a control unit and a timing unit. The control unit is used to periodically drive the trigger push rod 72 to retract.

[0031] It should be further noted that the support frame 2 is equipped with a limiting support rod (not shown in the figure) for supporting the cleaning scraper 1, which is used to prevent the cleaning scraper 1 from tilting excessively when it is tilted downwards and rotating without being subjected to force.

[0032] With the above structural setup, the following steps are included when using it: In the initial state, the limit seat 32 and the tilting arm 33 are located at one end close to the power distribution component 7, while the telescopic disc 71 is in the extended state. The connecting pin 712 on the telescopic disc 71 is inserted into the reciprocating screw 5, which transmits the power of the driven wheel 62 to the reciprocating screw 5. The reciprocating screw 5 drives the limit seat 32 and the tilting arm 33 to reciprocate on the cleaning scraper 1. Finally, the limit seat 32 returns to its original position and contacts the trigger on the trigger push rod 72. When the trigger on the trigger push rod 72 is activated, the control unit and timing unit start. The control unit controls the output end of the trigger push rod 72 to extend and push the telescopic disc 71 to retract, causing the connecting pin 712 to disengage from the reciprocating screw 5. At the same time, the output end of the trigger push rod 72 inserts into the connecting chuck 711. At this time, the power of the driven wheel 62 is transmitted to the cleaning scraper 1, and the reciprocating screw 5 loses power and stops rotating. After the cleaning scraper 1 obtains power, the elastic force required for the torsion of the return torsion spring 7111 is greater than the weight of the cleaning scraper 1. This will cause the cleaning scraper 1 to approach the roller 01 and continuously contact the roller 01. During the contact process, the cleaning scraper 1 will be limited by the roller 01. At this time, the continuous output of the driven wheel 62 will drive the reset torsion spring 7111 to rotate, thus preventing the driven wheel 62 from slipping on the transmission belt due to the limitation of the cleaning scraper 1 and the roller 01. This ensures that the cleaning scraper 1 can continuously contact the roller 01 during the period when the trigger push rod 72 connects the cleaning scraper 1 and the telescopic disc 71, without hindering the normal output of the driven wheel 62. After the cleaning scraper 1 has been in contact with the roller 01 for a period of time, the push rod 72 is triggered to retract under the control of the timing unit and the control unit. At this time, the telescopic disc 71 extends again under the push of the resisting spring 74, the cleaning scraper 1 disengages from the driven wheel 62, and the reciprocating screw 5 re-engages with the driven wheel 62 and receives the power of the driven wheel 62. By repeating the above steps, it can be ensured that during the continuous contact between the cleaning scraper 1 and the roller 01 driven by the driven wheel 62, the inclined swing arm 33 set on the cleaning scraper 1 stops running, so as to avoid the operation of the inclined swing arm 33 affecting the cleaning scraper 1's scraping of the roller 01 surface. After the cleaning scraper 1 and the roller 01 have been in contact for a period of time, the cleaning scraper 1 rotates and disengages from the roller 01. At this time, driven by the reciprocating screw 5 and the driven wheel 62, the inclined swing arm 33 is driven to reciprocate on the cleaning scraper 1 to clean the dirt accumulated on the cleaning scraper 1, thereby effectively improving the cleaning efficiency.

[0033] In this application, it should be added that the telescopic column 73 and the abutment spring 74 are disposed inside the connecting plate 75. The abutment spring 74 is used to push the telescopic plate 71 and the connecting pin 712 disposed thereon to re-engage with the reciprocating screw 5 and drive the reciprocating screw 5 to run when the trigger push rod 72 retracts.

[0034] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
