Description

Technical Field

[0001] This utility model relates to the field of annular belt cleaning, specifically to a device for automatic cleaning and recycling of annular belt conveyors. Background Technology

[0002] Currently, my country is vigorously advocating occupational health and safety, improving the working environment, and reducing labor intensity. The cigarette manufacturing production line is large and complex, with circular belt conveyors serving as raw material transport equipment between various processes. A complete cigarette manufacturing production line requires approximately 30 different models of circular belt conveyors as auxiliary equipment. Due to process and procedure requirements, most conveyor lengths are over 8 meters, with some reaching 15-30 meters. Existing circular belt conveyors, limited by power, only have a single spiral brush installed behind the tension roller at the head of the conveyor. The belt surface is cleaned by the counter-rotating spiral brush. Since there is only one cleaning point, it cannot meet the belt cleaning requirements. After prolonged use, a large amount of material adheres to the surface of the tension roller before the brush, causing irregular bumps on the roller surface and leading to belt skipping. This not only affects the cleaning effect of the brush behind the roller but also, due to belt vibration, disperses uncollected fine dust into the surrounding air, causing dust pollution and harming human health.

[0003] Currently, the adhering material swept off the conveyor belt by the roller brush is collected using a ash collection tray installed under the conveyor body. Operators need to clean and collect the ash collection tray and the ground around the equipment 2-3 times per shift. Because most annular belt conveyors are quite long, and due to process requirements, the installation height difference of the equipment is very large, it is extremely inconvenient to clean, and time-consuming and labor-intensive. Utility Model Content

[0004] This invention addresses the problem that existing belt cleaning devices for annular belt conveyors cannot effectively clean the belts, and the dust pollution caused by belt skipping. Therefore, it provides an automatic cleaning and recycling device for annular belt conveyors.

[0005] The technical solution of this utility model is:

[0006] An automatic cleaning and recycling device for an annular belt conveyor includes a floating belt brush mechanism;

[0007] The floating belt brush mechanism includes a brush, a brush mounting beam, a sliding guide post, a compensating spring, an angle adjustment seat, and a symmetrical mounting plate.

[0008] The brush is connected to the side plane of the brush mounting beam. The bottom of the brush mounting beam is fixedly connected to the sliding guide post. The sliding guide post is inserted into the sleeve in the longitudinal direction of the tilt adjustment seat and is limited at the bottom by a nut. The tilt adjustment seat is fixedly connected to the symmetrical mounting plate in the lateral direction. The symmetrical mounting plate is fixedly connected to the bent wall panels on both sides of the belt conveyor body by bolt assembly. A compensation spring is installed on the sliding guide post. The compensation spring is set between the sliding guide post and the tilt adjustment seat. By adjusting the installation height of the symmetrical mounting plates on both sides, the compensation spring has a certain amount of compression.

[0009] Furthermore, the angle at which the end of the tilt adjustment seat is mounted on the symmetrical mounting plate is 10°–15°, and the brush mounted on the tilt adjustment seat forms an angle of 10°–15° with the symmetrical mounting plate, so that the brush constitutes a forward-tilting structure and the brush contacts the bottom of the annular belt.

[0010] Furthermore, the brush is made of polypropylene, and the brush base is a perforated anti-static nylon bristle brush. Multiple brushes are arranged below the body of the belt conveyor, and a set of brushes is horizontally fixed to the brush mounting beam by bolt assembly to form a cleaning unit.

[0011] Furthermore, the tilt adjustment seat includes a vertical plate and a sleeve fixed on the symmetrical mounting plate. The sliding guide post is inserted into the sleeve of the tilt adjustment seat, and a compensation spring is provided above the sleeve. When the sliding guide post drives the brush to move through the brush mounting beam, the compensation spring will push the sliding guide post upward, so that the brush is always in close contact with the bottom of the annular belt.

[0012] Furthermore, the longitudinal section of the symmetrical mounting plate is a Z-shaped structure, thereby forming a stepped surface. The longitudinal surface at the lower position of the mounting plate is fixedly connected to the tilt adjustment seat by bolt assembly, and the longitudinal surface at the higher position of the mounting plate is fixedly connected to the angle steel at the top of the belt conveyor support leg by bolt assembly.

[0013] Furthermore, the device for automatic cleaning and recycling of the annular belt conveyor also includes a centralized powder collection mechanism;

[0014] The centralized powder collection mechanism includes a collection hopper fixing bracket, a powder collection tray, a powder collection hopper, a discharge pipe, and a transfer trolley;

[0015] The collection hopper fixing bracket is fixedly connected to the outer plate at the inlet of the powder collection hopper. The longitudinal frame of the collection hopper fixing bracket is fixedly connected to the belt conveyor support leg by bolt assembly. The bottom of the powder collection hopper is fixedly connected to the discharge pipe. A transfer trolley is set directly below the discharge pipe.

[0016] Furthermore, the powder collection tray has a trough-shaped structure and is arranged obliquely above the powder collection hopper.

[0017] Furthermore, the belt conveyor body includes a tension roller and a head brush roller;

[0018] The tension roller rolls in contact with the annular belt, and the head brush roller is positioned above the powder collection tray.

[0019] Furthermore, the belt conveyor body also includes a belt conveyor head and a conveyor drive roller;

[0020] The drive roller of the conveyor is installed inside the head of the belt conveyor.

[0021] Furthermore, the tension roller and the head brush roller are installed inside the head of the belt conveyor body.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This invention employs a cleaning brush assembly consisting of multi-row polypropylene base perforated anti-static nylon filament bristles. The brushes are mounted on a floating support. Using a forward-tilting design, the brushes, driven by the belt's rotation, brush off any adhering material from the surface of the annular belt. The brushed-off material is collected in a powder collection hopper below and then falls into a transfer trolley through a discharge pipe. This invention is suitable for cleaning belts on various annular belt conveyors.

[0024] This invention allows for selection of the number of brushes to be added based on the degree of material adhesion, ensuring cleaning requirements are met. The floating belt brush assembly effectively eliminates the wear gaps in the brush bristles caused by long-term use. Brushes with a forward tilt angle further improve the cleaning effect. The belt tensioning roller with an anti-stick treatment on its surface ensures that no material adheres to the roller surface, thus eliminating belt skipping and preventing dust. The material under the brushes is collected into a transfer trolley via a centralized collection mechanism, facilitating material recycling and processing. Furthermore, because scattered material is collected centrally, operators no longer need to clean multiple times per shift; they only need to empty the transfer trolley periodically according to production output, thereby reducing the labor intensity of operators and minimizing pollution to the surrounding environment.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Specific implementation method one:

[0034] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor, which includes a floating belt brush mechanism.

[0035] The floating belt brush mechanism includes a brush 1, a brush mounting beam 2, a sliding guide post 3, a compensating spring 4, an angle adjustment seat 5, and a symmetrical mounting plate 6.

[0036] The brush 1 is connected to the side plane of the brush mounting beam 2. The bottom of the brush mounting beam 2 is fixedly connected to the sliding guide post 3. The sliding guide post 3 is inserted into the sleeve in the longitudinal direction of the tilt adjustment seat 5 and is limited at the bottom by a nut. The tilt adjustment seat 5 is fixedly connected to the symmetrical mounting plate 6 in the lateral direction. The symmetrical mounting plate 6 is fixedly connected to the bent wall panels on both sides of the belt conveyor body 13 by bolt assembly. A compensation spring 4 is installed on the sliding guide post 3. The compensation spring 4 is set between the sliding guide post 3 and the tilt adjustment seat 5. By adjusting the installation height of the symmetrical mounting plates 6 on both sides, the compensation spring 4 can have a certain amount of compression.

[0037] The floating belt brush mechanism is the core of this invention. The brush 1 is mounted on the brush mounting beam 2. A sliding guide post 3 is connected below the brush mounting beam 5. The sliding guide post 3 is inserted into the sleeve of the tilt adjustment seat. A compensating spring 4 is sleeved on the sliding guide post 3, located between the brush mounting beam 2 and the tilt adjustment seat 5. The entire mechanism is fixed to the belt conveyor legs 14 by symmetrical mounting plates, thus forming a modular cleaning unit that can float up and down and adjust the cleaning angle. Specific Implementation Method Two:

[0039] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor. The end of the tilt adjustment seat 5 is mounted on the symmetrical mounting plate 6 at an angle of 10°–15°, and the brush 1 mounted on the tilt adjustment seat 5 forms an angle of 10°–15° with the symmetrical mounting plate 6, so that the brush 1 is a forward-tilted brush 1, and the brush 1 contacts the bottom of the annular belt 15.

[0040] When the tilt adjustment seat 5 is installed on the symmetrical mounting plate 6, it forms a tilt angle of 10° to 15°. This angle causes the brush 1 to tilt forward relative to the belt rotation direction. The brush is not perpendicular to the annular belt at 15°, but rather has a significant tilt angle. The forward tilt design can more effectively scrape off the deposits on the annular belt 15, greatly improving cleaning efficiency. Specific implementation method three:

[0042] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for a ring belt conveyor. The brush 1 is made of polypropylene, and the base of the brush 1 is a perforated anti-static nylon bristle brush. Multiple brushes 1 are arranged below the body 13 of the belt conveyor, and each set of brushes 1 is horizontally fixed to the brush mounting beam 2 by bolt assembly to form a cleaning unit.

[0043] The base of the brush 1 is made of polypropylene (PP), and the bristles are made of anti-static nylon. Multiple sets of brushes are arranged laterally along the width of the belt and fixed to the brush mounting beam 2, forming a continuous cleaning belt. Multiple brushes 1 are installed side-by-side, covering the entire width of the annular belt 15. The anti-static function prevents dust from adhering to the bristles due to static electricity, maintaining cleaning effectiveness. The multiple sets ensure thorough cleaning without any blind spots. Specific implementation method four:

[0045] Combination Figure 1 — Figure 6This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor. The tilt adjustment seat 5 includes a vertical plate and a sleeve fixed on a symmetrical mounting plate 6. A sliding guide post 3 is inserted into the sleeve of the tilt adjustment seat 5, and a compensation spring 4 is provided above the sleeve. When the sliding guide post 3 drives the brush 1 to move through the brush mounting beam 2, the compensation spring 4 pushes the sliding guide post 3 upward, so that the brush 1 is always in close contact with the bottom of the annular belt 15.

[0046] The compensating spring 4 is always in a compressed state. When the bristles wear down and become shorter due to long-term use, or when there are slight undulations on the belt surface, the rebound force of the compensating spring 4 will push the sliding guide post 3 upward, causing the brush mounting beam 2 and the brush 1 to rise synchronously. This ensures that the brush 1 can always be in close contact with the bottom surface of the annular belt 15, automatically eliminating gaps caused by bristle wear and maintaining a stable cleaning pressure. Specific implementation method five:

[0048] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor. The symmetrical mounting plate 6 has a Z-shaped longitudinal section, which forms a stepped surface. The longitudinal surface at the lower position of the mounting plate 6 is fixedly connected to the tilt adjustment seat 5 by bolt assemblies, and the longitudinal surface at the higher position of the mounting plate 6 is fixedly connected to the bent wall plates on both sides of the belt conveyor body 13 by bolt assemblies.

[0049] The longitudinal section of the symmetrical mounting plate 6 is Z-shaped, which forms a stepped mounting surface. The lower side is used to fix the tilt adjustment seat 5, and the higher side is used to connect with the angle steel at the top of the belt conveyor support leg 14. The Z-shaped structure of the symmetrical mounting plate 6 solves the problem of height difference between different components, making the installation and height adjustment of the entire floating mechanism very convenient. Specific implementation method six:

[0051] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor, which further includes a centralized powder collection mechanism.

[0052] The centralized powder collection mechanism includes a collection hopper fixing bracket 10, a powder collection tray 8, a powder collection hopper 9, a discharge pipe 11, and a transfer trolley 12.

[0053] The collection hopper fixing bracket 10 is fixedly connected to the outer plate at the entrance of the powder collection hopper 9. The longitudinal frame of the collection hopper fixing bracket 10 is fixedly connected to the belt conveyor support leg 14 by bolt assembly. The bottom of the powder collection hopper 9 is fixedly connected to the discharge pipe 11. A transfer trolley 12 is provided directly below the discharge pipe 11. Specific implementation method seven:

[0055] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor. The powder collection tray 8 has a trough-shaped structure and is arranged obliquely above the powder collection hopper 9.

[0056] The powder collection tray 8 is designed in the shape of a trough and is installed at an angle above the powder collection hopper 9. The inclined trough structure greatly expands the material receiving area and uses gravity guidance to smoothly and without omission guide the material brushed off the belt into the powder collection hopper 9 below. Detailed implementation method eight:

[0058] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor, wherein the conveyor body 13 includes a tension roller 7 and a head brush roller 16.

[0059] The tension roller 7 rolls in contact with the annular belt 15, and the head brush roller 16 is positioned above the powder collection tray 8. It is used to maintain belt tension. The head brush roller 16 is an existing cleaning component of the original equipment and is positioned directly above the powder collection tray 8. The original head brush roller 16 is retained and utilized, and together with the new floating brush mechanism, it forms a dual cleaning system, further improving the cleaning effect. Specific implementation method nine:

[0061] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor. The belt conveyor body 13 further includes a belt conveyor head 17 and a conveyor drive roller 18.

[0062] The conveyor drive roller 18 is installed inside the head 17 of the belt conveyor.

[0063] The conveyor drive roller 18 is the power source for the conveyor. This invention is a modification of the existing power system of the conveyor, without changing its core drive components. Furthermore, the modifications mainly focus on the floating belt brush mechanism in the middle of the equipment and the centralized powder collection mechanism below, making it suitable for widespread application and installation on existing equipment. Specific Implementation Method Ten:

[0065] Combination Figure 1 — Figure 6 This embodiment describes an automatic cleaning and recycling device for an annular belt conveyor, wherein the tension roller 7 and the head brush roller 16 are disposed inside the belt conveyor head 17 of the belt conveyor body 13.

[0066] Working principle:

[0067] By adjusting the installation angle of the tilt adjustment seat 5 of the floating belt brush mechanism, the brush 1 installed above it forms an angle that tilts forward relative to the direction of rotation of the annular belt. This installation tilt angle can greatly improve the cleaning function of the brush.

[0068] The brush mounting beam 2 is installed on the tilt adjustment seats 5 on both sides by sliding guide posts 3 installed at both ends passing through the compensating spring 4. By adjusting the installation height of the symmetrical mounting plates 6 on both sides, the compensating spring 4 can have a certain amount of compression. During the use of the belt conveyor, the compression can be used to eliminate the gaps caused by the wear of the brush bristles, and the brush bristles can be continuously stressed to improve the cleaning effect.

[0069] Material brushed off by the original roller brush and floating belt brush mechanism of the belt conveyor is collected by the extended powder collection tray 8 and powder collection hopper 9 of the centralized powder collection mechanism, and falls into the transfer trolley 12 through the lower-connected discharge pipe 11. The collection hopper fixing bracket 10 is installed above the belt conveyor support leg 15. By adjusting its installation height, the centralized powder collection mechanism can be positioned directly below the floating belt brush mechanism, ensuring that all brushed material falls into the centralized powder collection mechanism. This facilitates material recycling and reduces the labor intensity of operators. Replacing the original belt tensioning roller of the belt conveyor with an anti-stick belt tensioning roller with an anti-stick surface treatment can prevent material adhesion and avoid belt skipping. In addition, the use of the centralized powder collection mechanism and the anti-stick belt tensioning roller together can greatly reduce dust pollution to the surrounding environment, providing operators with a relatively healthy working environment.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments without departing from the scope of the present utility model's technical solution, based on the technical essence of the present utility model and within the spirit and principles of the present utility model, shall still fall within the protection scope of the present utility model's technical solution.
