Description

Technical Field

[0001] This application relates to the field of tobacco machinery cleaning equipment technology, specifically a brush roller cleaning device that is easy to disassemble and assemble. Background Technology

[0002] In the tobacco processing industry, the conveyor belt is a key piece of equipment responsible for transporting tobacco or tobacco packages, and its cleanliness directly affects the efficiency and quality of material transport. Due to prolonged operation, dust, tobacco debris, and other impurities easily accumulate on the surface of the conveyor belt. If not cleaned promptly, this can lead to belt wear, misalignment, or slippage, and also affect the cleanliness and safety of the production environment. Currently, brush rollers are commonly used for online cleaning of the conveyor belt. However, with extended use, the brush rollers themselves become heavily contaminated with tobacco sludge and leaf debris, resulting in reduced cleaning effectiveness and potentially creating a breeding ground for tobacco beetles.

[0003] However, existing brush roller devices do not consider the need for rapid maintenance in their structure, and their disassembly and cleaning process is extremely inconvenient. Typically, three operators are required to work together, first removing multiple fasteners, then carefully separating the roller body from the transmission components. The entire process can take tens of minutes or even longer. This frequent and inefficient disassembly and assembly not only significantly increases labor costs and intensity but also reduces the effective cleaning time of the equipment, seriously affecting the overall production line rhythm and the continuous cleanliness of the conveyor belt. Furthermore, untimely cleaning can lead to a series of chain reactions such as material retention and quality degradation.

[0004] Therefore, this application proposes a brush roller cleaning device that is easy to disassemble and assemble quickly, which can realize the rapid disassembly and installation of brush rollers, reduce maintenance difficulty and labor intensity, and improve cleaning efficiency and equipment operation reliability.

[0013] As a further improvement of this application, the second elastic positioning component includes a second spring and a second limiting member; the second insertion part has a second mounting cavity, and the radial sidewall of the second mounting cavity has a second through hole communicating with the outside; the sidewall of the connecting sleeve has a second limiting hole corresponding to the position of the second insertion hole; the second spring is housed in the second mounting cavity, the second limiting member is movably disposed in the second through hole, and under the elastic force of the second spring, it partially protrudes from the outer surface of the second insertion part, and the second limiting member can be engaged in the second limiting hole when it protrudes, so as to achieve axial positioning of the brush roller and the connecting sleeve.

[0014] As a further improvement of this application, the end of the first plug portion is provided with an opening communicating with the first mounting cavity, and is threadedly connected with a first end cap for encapsulating the first spring and the first limiting member; the end of the second plug portion is provided with an opening communicating with the second mounting cavity, and is threadedly connected with a second end cap for encapsulating the second spring and the second limiting member.

[0015] As a further improvement of this application, a third spring is also provided in the second insertion hole of the connecting sleeve, the depth of the second insertion hole is greater than the insertion depth of the second insertion part; the third spring is located between the bottom of the second insertion hole and the end face of the second insertion part, and is used to provide axial elastic preload to the brush roller.

[0016] As a further improvement of this application, the mating cross sections of the first plug-in portion and the first socket, and the second plug-in portion and the second socket are all non-circular, in order to transmit torque and prevent relative rotation.

[0017] The technical solution provided in this application may include the following beneficial effects:

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] Figure 1 An embodiment of the brush roller cleaning device of this application that is easy to disassemble and assemble is shown; see [link to relevant documentation]. Figure 1 In this embodiment, the easy-to-disassemble brush roller cleaning device includes: a brush roller 1, a base 2, a synchronous pulley 3, and a transmission connection mechanism 4.

[0028] Among them, see Figure 1 and Figure 2The brush roller 1 is horizontally positioned above the conveyor belt; the base 2 is located on one side of the conveyor belt along its length, and has a mounting hole 21 on it for one end of the brush roller 1's rotating shaft 11 to be rotatably inserted; the synchronous pulley 3 is located on the other side of the conveyor belt along its length and is used to connect with an external drive mechanism; the transmission connection mechanism 4 includes a transition shaft 41 and a connecting sleeve 42, one end of the transition shaft 41 is coaxially fixedly connected to the synchronous pulley 3, and the other end forms a first insertion part 411; the connecting sleeve 42 has a first insertion hole 421 and a second insertion hole 422 at its two axially opposite ends, the first insertion hole 421 is for the first insertion part 411 to be inserted, and the transition shaft 41 is releasably locked to the connecting sleeve 42 by a first elastic positioning component 43; the other end of the brush roller 1's rotating shaft 11 forms a second insertion part 111, the second insertion part 111 is inserted into the second insertion hole 422, and the brush roller 1 is releasably locked to the connecting sleeve 42 by a second elastic positioning component 44. During use, the first insertion part 411 and the first insertion hole 421, and the second insertion part 111 and the second insertion hole 422 are respectively connected and engaged, combined with the first elastic positioning component 43 and the second elastic positioning component 44 to achieve a releaseable locking mechanism. This solves the problem that the disassembly and cleaning of the existing brush roller 1 requires multiple people to work together, and the operation is cumbersome and time-consuming. It reduces maintenance difficulty and labor intensity, enabling operators to quickly complete the assembly and disassembly of the brush roller 1, ensuring the timeliness and effectiveness of cleaning operations. This avoids problems such as conveyor belt slippage, deviation, wear, and material retention caused by untimely cleaning, while also helping to maintain a clean working environment and improving the overall equipment reliability and production efficiency.

[0029] Further, see Figure 3 The first elastic positioning component 43 includes a first spring 431 and a first limiting member 432. The first insertion portion 411 has a first mounting cavity 411a inside, and a first through hole 411b communicating with the outside on its radial sidewall. Correspondingly, a first limiting hole 423 is provided on the sidewall of the connecting sleeve 42, communicating with the first insertion hole 421. During assembly, the first spring 431 is housed at the bottom of the first mounting cavity 411a, and the first limiting member 432 is movably disposed in the first through hole 411b, and partially protrudes from the outer surface of the first insertion portion 411 under the elastic force of the first spring 431. When the first insertion portion 411 is inserted into the first insertion hole 421 of the connecting sleeve 42, the first limiting member 432 is compressed and retracts inward until it aligns with the first limiting hole 423. Then, under the push of the first spring 431, it quickly snaps into the hole, accompanied by a crisp engagement sound, achieving reliable axial locking between the transition shaft 41 and the connecting sleeve 42. Not only does it eliminate the need for tools required for traditional bolt or pin connections by utilizing the combination of springs and limiting components, allowing operators to complete connection and separation with one hand and improving assembly and disassembly efficiency, but its self-locking characteristics also prevent accidental loosening due to vibration during equipment operation, ensuring the continuity and stability of power transmission and reducing maintenance time and labor costs.

[0030] Further, see Figure 3 The second elastic positioning component 44 includes a second spring 441 and a second limiting member 442. A second mounting cavity 111a is formed in the second insertion portion 111 at the end of the brush roller 1 shaft 11. A second through hole 111b communicating with the outside is provided on the radial sidewall of this mounting cavity. A second limiting hole 424 is correspondingly provided on the sidewall of the connecting sleeve 42 at a position communicating with the second insertion hole 422. The second spring 441 is housed at the bottom of the second mounting cavity 111a, and the second limiting member 442 is movably disposed in the second through hole 111b. Under the elastic force of the second spring 441, a portion of the second limiting member 442 continuously protrudes from the outer surface of the second insertion portion 111. When the operator aligns the second insertion part 111 of the brush roller 1 with and inserts it into the second insertion hole 422 of the connecting sleeve 42, the second limiting member 442 is first squeezed inward by the edge of the hole and retracts. When it is inserted into place and the second limiting member 442 is aligned with the second limiting hole 424, it quickly pops out and locks into the hole under the action of the second spring 441, making a clear locking sound, thereby reliably locking the brush roller 1 and the connecting sleeve 42 together and achieving axial limiting. This structure works in conjunction with the first elastic positioning component 43 of the transition shaft 41 on the other side to form a complete quick-release connection system, which not only makes the disassembly and installation of the brush roller 1 extremely simple—the operation can be completed by pressing the limiting member with one hand, saving time and effort, but also avoids axial movement or accidental disengagement that may occur in the equipment under high-speed operation or vibration environment, enhances the stability and safety of the transmission connection, and also provides convenience for frequent cleaning and maintenance, improving the maintainability and operating efficiency of the overall equipment.

[0031] Optionally, both the first limiting member 432 and the second limiting member 442 can adopt a standard cylindrical structure. Correspondingly, the first through hole 411b, the first limiting hole 423, the second through hole 111b, and the second limiting hole 424 are all set as circular holes. This ensures the smoothness and flexibility of the limiting member sliding in the through hole, allowing it to accurately pop out or retract under the action of the spring, reducing the jamming phenomenon that may occur due to improper structure.

[0032] Optionally, to prevent the first limiting member 432 and the second limiting member 442 from completely dislodging from their respective through holes under the repeated action of the spring or strong vibration, thereby causing part loss or functional failure, a retaining ring structure can be machined at one end of the first limiting member 432 adjacent to the first spring 431 and at one end of the second limiting member 442 adjacent to the second spring 441. The outer diameter of the retaining ring is larger than the diameter of the through hole in which it is located. When it moves with the limiting member to the opening position, it can be effectively blocked by the edge of the hole, thereby reliably limiting the range of motion of the limiting member inside the through hole.

[0033] Further, see Figure 4 The first insertion part 411 has an opening at its end that communicates with the first mounting cavity 411a, and a first end cap 412 is screwed on thereon via a threaded connection. The first end cap 412 reliably encapsulates the first spring 431 and the first limiting member 432 housed within the first mounting cavity 411a. Correspondingly, the second insertion part 111 also has an opening at its end that communicates with the second mounting cavity 111a, and a second end cap 112 is screwed on thereon via a threaded connection. The second end cap 112 encapsulates the second spring 441 and the second limiting member 442 within the second mounting cavity 111a. Not only is the structure simple and easy to assemble and disassemble, but more importantly, it provides independent encapsulation and protection space for the springs and limiting members in the first and second elastic positioning assemblies 44, preventing dust, soot, and other impurities from entering the mounting cavity, avoiding spring jamming or limiting member malfunction due to dirt accumulation, and ensuring the long-term reliability of the elastic positioning function. When maintenance or replacement of the elastic positioning component is required, the operator only needs to use a general tool to unscrew the end cap to directly clean or replace the internal spring or limiting component. The maintenance work becomes extremely simple and quick, without the need to disassemble the entire transmission connection mechanism 4 or large components, reducing the difficulty and time cost of daily maintenance, while also extending the service life of the entire quick-release mechanism and ensuring the continuous and stable operation of the brush roller cleaning device.

[0034] Further, see Figure 4 A third spring 45 is also added inside the second insertion hole 422 of the connecting sleeve 42, and the depth of the second insertion hole 422 is specially designed to be greater than the axial insertion depth of the second insertion part 111, thereby forming a receiving space between the two end faces; the third spring 45 is installed in this space, with its two ends abutting against the bottom of the second insertion hole 422 and the end face of the second insertion part 111, respectively. The third spring 45 continuously applies an axial elastic preload force pointing in the disengagement direction to the brush roller 1. Not only does it eliminate axial clearance caused by manufacturing tolerances or wear during daily operation, ensuring stable transmission between the brush roller 1 and the connecting sleeve 42 without any movement, but also, when disassembly is required, once the operator presses the second limiting member 442 to disengage it from the second limiting hole 424, the preload stored in the third spring 45 is instantly released, automatically and smoothly pushing the second insertion part 111 of the brush roller 1 out of the connecting sleeve 42 a certain distance, assisting in the separation operation. This makes the disassembly process more effortless, smooth, and requires no tools to pry, avoiding damage to the connecting parts during disassembly. At the same time, this constant elastic preload also ensures that the second limiting member 442 and the second limiting hole 424 are always in a stable contact state, enhancing the reliability of the locking and further improving the user experience and long-term stability of the entire quick-release device.

[0035] Optionally, the mating cross-sections of the first insertion part 411 and the first insertion hole 421, and the second insertion part 111 and the second insertion hole 422, are all designed as consistent non-circular structures, such as rectangular, D-shaped, or spline. When the first insertion part 411 of the transition shaft 41 is inserted into the first insertion hole 421 of the connecting sleeve 42, and the second insertion part 111 of the brush roller 1 is inserted into the second insertion hole 422, relative rotation between the components is impossible. This ensures that the driving torque can be efficiently and without loss transmitted from the synchronous pulley 3 through the transition shaft 41 and the connecting sleeve 42 to the brush roller 1, guaranteeing the reliability and stability of the cleaning power. This non-circular mating structure fundamentally eliminates the slippage and free rotation phenomena that may occur with traditional round shaft and round hole mating, not only improving transmission efficiency but also reducing component wear caused by relative sliding and extending the service life of the device. At the same time, it perfectly combines with the axial limiting function of the elastic positioning component to achieve circumferential locking, forming a complete quick-release solution that can solve both axial fixation and circumferential transmission with just a simple plug-and-play operation, simplifying the assembly and disassembly process and improving the maintainability of the equipment.

[0036] For example, the working principle of an easy-to-disassemble brush roller cleaning device is illustrated below:

[0037] An external drive mechanism rotates the synchronous pulley 3, and torque is transmitted to the transition shaft 41 via a key connection. The non-circular first insertion part 411 at the front end of the transition shaft 41 is inserted into the corresponding first insertion hole 421 of the connecting sleeve 42, and is locked into the first limiting hole 423 by the first limiting member 432 in the first elastic positioning component 43 under the action of a spring, achieving axial locking and circumferential transmission. At the same time, the non-circular second insertion part 111 at the end of the brush roller 1 shaft 11 is inserted into the second insertion hole 422 at the other end of the connecting sleeve 42, and is also locked by the second elastic positioning component 44. Thus, rotational power is transmitted from the transition shaft 41 to the connecting sleeve 42 without loss, ultimately driving the brush roller 1 to rotate synchronously and continuously clean the surface of the conveyor belt below.

[0038] When it is necessary to disassemble, clean, or replace the brush roller 1, the operator only needs to press the first limiting member 432 and the second limiting member 442 simultaneously to compress the springs and disengage them from the corresponding limiting holes, thereby releasing the axial lock. At this time, under the elastic force of the third spring 45 pre-placed at the bottom of the second insertion hole 422, the brush roller 1 will be slightly pushed out, assisting the operator in easily pulling the entire brush roller 1 assembly out from the connecting sleeve 42 and the base 2 side, allowing for quick disassembly without tools. The installation process is the reverse of the above steps; simple plugging and a clear locking sound ensure accurate reset, improving maintenance efficiency.

[0039] In this embodiment, the problem of cumbersome, time-consuming, and labor-intensive disassembly of the brush roller 1 in the prior art is solved through structural innovation. Its core lies in the use of a quick-release transmission connection mechanism 4, consisting of a transition shaft 41, a connecting sleeve 42, and double-sided elastic positioning components, supplemented by a non-circular cross-section for torque transmission. This not only enables tool-free quick insertion and removal and reliable locking of the brush roller 1, ensuring the stability of power transmission, but also makes the disassembly process more effortless and smooth through the auxiliary ejection design of the built-in spring. Simultaneously, the independently maintainable encapsulated end cap structure extends the service life of the mechanism. This reduces the labor intensity and time cost of equipment maintenance, improves the efficiency and continuity of cleaning operations, and has good practicality and economic value.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
