Description

Technical Field

[0001] The present disclosure relates to the technical field of roller brush cleaning, and in particular, to a roller brush cleaning mechanism. Background Art

[0002] Roller brushes are generally used in conjunction with mechanical equipment to clean the surfaces of various equipment through the bristles on the outer surface of the roller brush. After using it for a period of time, it is usually necessary to clean the bristles of the roller brush to ensure the cleaning effect of the roller brush. In the related art, a scraper is usually set on one side of the bristles of the roller brush. During the rotation of the roller brush, the scraper cleans the roller brush. However, in actual applications, due to changes in working conditions, workpieces, etc., it may be necessary to replace the roller brush with a roller brush of a different material or change the rotation speed of the original roller brush, which will cause the distance between the scraper and the roller brush bristles to change. If the distance between the scraper and the roller brush bristles increases, there may be a situation where cleaning is not in place and the cleaning effect is poor; if the distance between the scraper and the roller brush bristles decreases, the roller brush bristles may be subjected to unnecessary excess movement and increase the risk of falling off.

DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are inside and outside relative to the corresponding component's own outline. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element and do not represent order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. It will be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and are not used to limit it.

[0026] According to a specific embodiment of the present disclosure, a roller brush cleaning mechanism is provided. Figures 1 to 5 An embodiment of the roller brush cleaning mechanism is shown. Figures 1 to 5 As shown, the roller brush cleaning mechanism includes: a base 1, which defines a accommodating cavity for accommodating the roller brush 6; a cleaning component 2, which includes a paddle 21 with a cleaning portion 215, the paddle 21 is arranged in the accommodating cavity and the cleaning portion 215 is used to be inserted into the bristles of the roller brush 6; and a distance adjustment structure 3, which is used to adjust the distance between the paddle 21 and the roller brush 6.

[0027] Through the above technical solution, in the roller brush cleaning mechanism provided by the present disclosure, the roller brush 6 is accommodated in the accommodating cavity of the base 1, and the cleaning portion 215 of the paddle 21 is inserted into the bristles of the roller brush 6. When the roller brush 6 rotates, the cleaning portion 215 of the paddle 21 will hinder the movement of the bristles, causing the bristles to bend and store elastic potential energy. When the bristles are bent to a certain extent, the bristles will break away from the obstruction of the paddle 21, and the potential energy stored in the bristles will be released in a relatively short time. In this process, the pollutants (such as graphite, etc.) attached to the bristles will be shaken off, thereby achieving the cleaning of the bristles. When the distance between the roller brush 6 (i.e., the bristles of the roller brush 6) and the paddle 21 changes, it is only necessary to adjust the distance between the paddle 21 and the roller brush 6 (i.e., adjust the size of the overlapping area between the paddle 21 and the roller brush 6) through the distance adjustment structure 3, thereby achieving the purpose of the paddle 21 regulating the compression amount of the bristles of the roller brush 6. Specifically, when the distance between the paddle 21 and the roller brush 6 increases, the distance between the paddle 21 and the roller brush 6 can be reduced to a suitable position through the distance adjusting structure 3, and when the distance between the paddle 21 and the roller brush 6 decreases, the distance between the paddle 21 and the roller brush 6 can be increased to a suitable position through the distance adjusting structure 3, thereby ensuring that the distance between the paddle 21 and the roller brush 6 is always in a suitable position, which can not only ensure the cleaning effect of the roller brush 6, but also avoid the situation where the bristles of the roller brush 6 are subjected to unnecessary and redundant stirring, which is beneficial to improving the service life of the roller brush 6.

[0028] It should be noted that the distance between the paddle 21 and the roller brush 6 can be understood as the distance between the end of the cleaning portion 215 of the paddle 21 facing the end of the bristles of the roller brush 6 and the root of the bristles of the roller brush 6, or can be understood as the distance between the end of the cleaning portion 215 of the paddle 21 facing the end of the bristles of the roller brush 6 and the head of the bristles of the roller brush 6 (the end away from the root). The present disclosure does not impose any restrictions on this, and those skilled in the art can choose according to actual needs. In addition, during cleaning, the rotation of the roller brush 6 can be performed manually or mechanically driven to rotate the roller brush 6. For example, the roller brush 6 is installed on the corresponding rotating shaft of the mechanical equipment, and the roller brush cleaning mechanism is installed below the roller brush 6. When the roller brush 6 is driven to rotate for cleaning, the roller brush cleaning mechanism can clean the roller brush 6, that is, perform a self-cleaning operation of the roller brush 6. The roller brush 6 is not directly connected to the roller brush cleaning mechanism, which is convenient to disassemble, and reduces the maintenance cost of the roller brush 6 and improves the maintenance efficiency. The present disclosure does not impose any restrictions on this, and those skilled in the art can selectively set it according to actual needs.

[0029] In addition, the paddle 21 can be constructed in any suitable manner. For example, the paddle 21 can be made of sintered steel, which has good self-lubricating properties and a harderness than the nylon material used for the bristles of the roller brush 6. It can effectively reduce its own wear and tear and increase the life of components, etc. It can also be made of other suitable materials, and the present disclosure does not impose any restrictions on this.

[0030] In the specific embodiment provided by the present disclosure, the pitch adjustment structure 3 can be configured in any suitable manner. Optionally, the pitch adjustment structure 3 can include a screw rod 31 and a nut (not shown in the figure) in a spiral transmission cooperation. The nut is arranged on the base 1. The screw rod 31 is sleeved with a nut. One end of the screw rod 31 is provided with an operating portion 311, and the other end passes through the base 1 and is connected to the paddle 21. The screw rod 31 can rotate around its own axis to drive the paddle 21 to move toward or away from the roller brush 6. Since the nut is arranged on the base 1, when the screw rod 31 is manipulated to rotate around its own axis by the operating portion 311, the spiral transmission cooperation between the nut and the screw rod 31 can convert the rotary motion between the screw rod 31 and the nut into a linear motion by the spiral engagement with the threaded surface, that is, the linear motion of the screw rod 31. The screw rod 31 passes through the base 1 and is connected to the paddle 21. Therefore, the screw rod 31 can drive the paddle 21 to move toward or away from the roller brush 6, thereby realizing the adjustment of the distance between the paddle 21 and the roller brush 6. Specifically, when the screw 31 is screwed out relative to the nut (i.e., the base 1), the screw 31 can drive the paddle 21 to move away from the roller brush 6 to increase the distance between the paddle 21 and the roller brush 6. When the screw 31 is screwed in relative to the nut (i.e., the base 1), the screw 31 can drive the paddle 21 to move toward the roller brush 6 to reduce the distance between the paddle 21 and the roller brush 6.

[0031] In some embodiments of the present disclosure, the nut can be set independently of the base 1. When in use, the nut only needs to be installed on the base 1, and the end of the screw rod 31 passes through the nut and the base 1 in sequence and is connected to the paddle 21. Figures 2 to 5 As shown, the nut can be integrally formed with the base 1, that is, it can be understood that the inner hole of the nut is a threaded hole 32 formed on the base 1, the threaded hole 32 penetrates the side wall of the base 1 and has an internal thread, and the outer peripheral surface of the screw 31 is provided with an external thread that can be spirally matched with the internal thread. In other embodiments of the present disclosure, the nut can also be arranged in other ways, and the present disclosure does not impose any restrictions on this. The present disclosure will be exemplarily introduced below by taking the nut and the base 1 as an example of integrally forming.

[0032] In the specific embodiments provided in the present disclosure, reference is made to Figures 1 to 5As shown, the distance adjustment structure 3 may also include a limiter 33, which has a locked state and an unlocked state. When the limiter 33 is in the locked state, the limiter 33 is used to limit the circumferential rotation of the screw rod 31, thereby limiting the screw rod 31 from being screwed in or out relative to the base 1, so as to avoid the situation where the paddle 21 moves when there is no need to adjust the position of the paddle 21. When the limiter 33 is in the unlocked state, the limiter 33 releases the restriction on the screw rod 31. At this time, the screw rod 31 can rotate around its own axis, thereby being screwed in or out relative to the base 1, so as to adjust the distance between the paddle 21 and the roller brush 6. In other words, when it is necessary to adjust the distance between the paddle 21 and the roller brush 6, the limiter 33 is in the unlocked state and then adjusted. After the adjustment is completed, the limiter 33 is switched to the locked state, so that the paddle 21 can be kept in the adjusted position, and the reliability is high.

[0033] The stopper 33 may be constructed in any suitable manner. Figures 1 to 5 As shown, the stopper 33 is constructed as a first fastener 331, one end of the first fastener 331 is formed as an operating end, and the other end can be axially movable through the base 1 to switch between the first position and the second position. In the first position, the end of the first fastener 331 abuts against the outer peripheral surface of the screw rod 31; in the second position, the end of the first fastener 331 is separated from the outer peripheral surface of the screw rod 31. The first fastener 331 is rotated by the operating end so that the first fastener 331 switches between the first position and the second position. In the first position, the end of the first fastener 331 abuts against the outer peripheral surface of the screw rod 31. At this time, the stopper 33 is in a locked state, which is used to limit the screw rod 31 from rotating in or out relative to the base 1, so as to avoid the situation where the paddle 21 moves when the position of the paddle 21 does not need to be adjusted. In the second position, the end of the first fastener 331 is disengaged from the outer peripheral surface of the screw 31. At this time, when the limit member 33 is in an unlocked state, the limit member 33 releases the restriction on the screw 31. At this time, the screw 31 can rotate around its own axis, thereby screwing in or out relative to the base 1, so as to adjust the distance between the paddle 21 and the roller brush 6.

[0034] In other embodiments of the present disclosure, the distance adjustment structure 3 can also be other embodiments, for example, a rack and pinion transmission mechanism, a ball screw transmission mechanism, a hydraulic transmission mechanism, a servo motor transmission mechanism, etc. The present disclosure does not impose any limitations on this, and those skilled in the art can selectively set it according to actual needs.

[0035] In the specific embodiments provided in the present disclosure, reference is made to Figures 1 to 5As shown, the paddle 21 may include a mounting portion 214, which is arranged opposite to the cleaning portion 215; the screw 31 is connected to the paddle 21 through a connecting structure 4, the connecting structure 4 includes a connecting member 41 and a second fastener 42, the connecting member 41 includes a main body 411 and a first connecting portion 412 and a second connecting portion 413 arranged opposite to each other on the main body 411, the first connecting portion 412 is connected to the screw 31, the second connecting portion 413 includes two clamping portions 4131, one end of each clamping portion 4131 is connected to the main body 411, and the other end is formed as a free end, and the two clamping portions 4131 are arranged opposite to each other, the mounting portion 214 is inserted between the two clamping portions 4131, and the second fastener 42 passes through the two clamping portions 4131 in sequence to fasten the mounting portion 214 between the two clamping portions 4131. The mounting portion 214 of the plectrum 21 is inserted between the two clamping portions 4131, and the first fastener 331 passes through the two clamping portions 4131 in sequence to fasten the mounting portion 214 between the two clamping portions 4131, thereby realizing the connection between the plectrum 21 and the second connecting portion 413, that is, realizing the connection between the plectrum 21 and the connecting member 41, and the second connecting portion 413 is connected to the screw rod 31, that is, realizing the connection between the screw rod 31 and the connecting member 41. Among them, there can be many ways to connect the second connecting portion 413 and the screw rod 31, for example, the second connecting portion 413 is connected to the screw rod 31 through a buckle structure, and the buckle structure includes a matching buckle and a slot, one of the buckle and the slot is provided with the clamping portion 312 of the screw rod 31, and the other is provided on the second connecting portion 413, and the present disclosure does not make any limitation to this. In addition, in other embodiments of the present disclosure, the connecting structure 4 can also be other connecting methods, and the present disclosure does not make any limitation to this.

[0036] Among them, when the connecting tube 22 described below is set at the end of the mounting portion 214 of the paddle 21, a tube groove for accommodating the connecting tube 22 can be set between the two clamping portions 4131. When connecting, the connecting tube 22 is inserted into the tube groove, and the mounting portion 214 of the paddle 21 is inserted between the two clamping portions 4131. Then, the first fastener 331 is passed through the two clamping portions 4131 in sequence to fasten the mounting portion 214 between the two clamping portions 4131 to achieve the connection between the paddle 21 and the second connecting portion 413.

[0037] In the specific embodiment provided by the present disclosure, a first elastic member is provided between the mounting portion 214 and the second connecting portion 413, and the first elastic member abuts between the mounting portion 214 and the second connecting portion 413; and / or, a second elastic member is provided between the screw 31 and the first connecting portion 412, and the second elastic member abuts between the screw 31 and the first connecting portion 412. During the rotation of the roller brush 6, since the position of the paddle 21 is fixed, when the rotation speed of the roller brush 6 is fast, the paddle 21 is subjected to a large force, and the bristles are easily damaged or broken. When the rotation speed of the roller brush 6 is slow, the paddle 21 is subjected to a small force, and the distance between the paddle 21 and the bristles can be further reduced to increase the force on the paddle 21 (the resistance near the root is large). Therefore, by providing the elastic member, when the paddle 21 is subjected to a large or small force, the position of the paddle 21 can be adjusted by compressing the elastic member. It should be noted that the compression amount and material parameters of the elastic member can be selectively designed according to the implementation situation, and the present disclosure does not impose any restrictions on this.

[0038] In the first embodiment of the present disclosure, a first elastic member may be provided between the mounting portion 214 and the second connecting portion 413, and the first elastic member abuts between the mounting portion 214 and the second connecting portion 413. When the paddle 21 is subjected to greater or lesser force, the position of the paddle 21 can be adjusted by compression of the first elastic member.

[0039] In a second embodiment of the present disclosure, a second elastic member is provided between the screw rod 31 and the first connecting portion 412, and the second elastic member abuts between the screw rod 31 and the first connecting portion 412; when the paddle 21 is subjected to greater or lesser force, the position of the paddle 21 can be adjusted by compression of the second elastic member.

[0040] In the third embodiment of the present disclosure, a first elastic member is provided between the mounting portion 214 and the second connecting portion 413, and the first elastic member abuts between the mounting portion 214 and the second connecting portion 413; and a second elastic member is provided between the screw rod 31 and the first connecting portion 412, and the second elastic member abuts between the screw rod 31 and the first connecting portion 412. When the paddle 21 is subjected to a large or small force, the position of the paddle 21 can be adjusted by the compression of the first elastic member and the second elastic member.

[0041] It should be noted that the above-mentioned first elastic member is arranged between the mounting portion 214 and the second connecting portion 413, which can be understood as: the first elastic member is arranged at any position between the mounting portion 214 and the second connecting portion 413, wherein the first elastic member can directly abut between the mounting portion 214 and the second connecting portion 413, or can indirectly abut between the mounting portion 214 and the second connecting portion 413. For example, referring to Figures 2 to 5As shown, the end of the mounting portion 214 facing the connecting member 41 is provided with the connecting tube 22 as described below, so the first elastic member can be arranged between the connecting tube 22 and the second connecting portion 413 (that is, between the mounting portion 214 and the second connecting portion 413), and the first elastic member abuts between the connecting tube 22 and the second connecting portion 413. Similarly, the second elastic member being arranged between the screw rod 31 and the first connecting portion 412 can be understood as: the second elastic member being arranged at any position between the screw rod 31 and the second connecting portion 413, wherein the second elastic member can directly abut between the screw rod 31 and the second connecting portion 413, or can indirectly abut between the screw rod 31 and the second connecting portion 413.

[0042] In the specific embodiments provided in the present disclosure, reference is made to Figures 2 to 5 As shown, a circulation channel 211 for the flow of cleaning liquid is defined in the paddle 21, and the circulation channel 211 includes a liquid inlet 212 and a liquid outlet 213. The liquid outlet 213 is arranged at the end of the cleaning portion 215 facing the roller brush 6, and the liquid inlet 212 is used to communicate with an external liquid supply device. The external liquid supply device transports the cleaning liquid to the liquid inlet 212 of the circulation channel 211, and then the liquid flows to the liquid outlet 213 in the circulation channel 211, and is further used to clean the roots of the bristles, so that the pollutants (such as graphite) attached to the bristles are cleaned, thereby further improving the cleaning effect of the roller brush 6 and extending its service life (when the pollutants are attached and the roller brush 6 is worn). In addition, the provision of the circulation channel 211 can also simplify the pipeline structure, reduce weight and reduce costs.

[0043] In the specific embodiments provided in the present disclosure, reference is made to Figures 2 to 5 As shown, the cleaning assembly 2 may further include a connecting tube 22, the connecting tube 22 includes a first end 221 and a second end 222, the first end 221 is connected to the liquid inlet 212, and the second end 222 is used to communicate with an external liquid supply device, and the cleaning liquid of the external liquid supply device is transported to the circulation channel 211 through the connecting tube 22. The outer peripheral surface of the first end 221 is provided with a plurality of water outlet holes 223, the plurality of water outlet holes 223 are evenly spaced along the axial direction of the connecting tube, and the plurality of water outlet holes 223 are located within the projection of the liquid inlet 212 in the first direction. Since the roller brush 6 usually has a certain width (a certain size in the axial direction), the paddle 21 is also provided with a corresponding size accordingly. In order to ensure that the roller brush 6 can be cleaned in place, it can be understood that the circulation channel 211 and the liquid inlet 212 and the liquid outlet 213 of the paddle 21 all extend along the length direction of the paddle 21. Therefore, by providing a plurality of water outlet holes 223, it is possible to ensure that the flow rate and water flow distribution of the cleaning liquid entering the circulation channel 211 are uniform, thereby increasing the flow rate and water flow distribution of the liquid outlet 213, that is, it is possible to ensure that each position of the roller brush 6 can be cleaned in place, and the cleaning effect is better.

[0044] In the specific embodiments provided in the present disclosure, reference is made to Figure 1 and Figure 2 As shown, the roller brush cleaning mechanism also includes a protective cover 5, which is installed in the accommodating cavity of the base 1 and defines a protective cavity 51. One end of the protective cavity 51 is open, and the other end is provided with an outlet 511 for the outflow of the cleaning liquid. The cleaning component 2 is located in the protective cavity 51. The provision of the protective cover 5 can guide the pollutants and the like cleaned from the roller brush 6. Specifically, the pollutants cleaned from the roller brush 6 enter the protective cavity 51 and flow out from the outlet 511 of the protective cavity 51. On the one hand, the pollutants can be collected (a sewage collection box is provided below the outlet 511 to achieve collection), and on the other hand, the base 1 and other components can be prevented from being damaged or corroded. Among them, the protective cavity 51 can be constructed in any suitable manner. Optionally, the protective cavity 51 can be constructed in a funnel shape, and the funnel-shaped opening is used to receive pollutants and cleaning liquid, and the outlet 511 is used to discharge pollutants and cleaning liquid.

[0045] In the specific embodiments provided in the present disclosure, reference is made to Figure 1 and Figure 2 As shown, the number of cleaning components 2 is set to be multiple, and multiple cleaning components 2 are arranged circumferentially at intervals on the base 1, and the number of distance adjustment structures 3 is the same as the number of cleaning components 2 and is arranged one-to-one. In order to ensure the cleaning effect, the cleaning components 2 can be set to be multiple, and the distances between the paddles 21 of the multiple cleaning components 2 and the roller brush 6 can be the same or different. Those skilled in the art can selectively design according to actual needs. Among them, each paddle 21 is correspondingly provided with a distance adjustment structure 3 to facilitate the adjustment of the position of the corresponding paddle 21. It should be noted that when adjusting, the position of one or any several paddles 21 among the multiple paddles 21 can be adjusted according to the adjustment requirements, or all of them can be adjusted. This disclosure does not impose any restrictions.
