Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery and equipment, and in particular to a steel nail cleaning device and a cleaning method for material conveying equipment. Background Art

[0002] In the process of cigarette production, the material conveyor used to transport materials is an indispensable conveying equipment. When it is necessary to use the material conveyor to increase the conveying height of the material, the surface of the conveyor belt of such material conveyor is usually evenly distributed with several steel nails. The steel nails can not only effectively drive the material to rise, but also prevent the material from sliding down during the upward process, causing material blockage. In actual production, after the material is added with materials and flavoring processes and absorbs moisture and liquid, it will become more adhesive. However, during the material transportation process, some materials will be entangled on the surface of the steel nails of the conveyor belt of the conveying equipment. Therefore, in order to ensure the quality of the next production batch of materials, it is necessary to clean the materials entangled on the surface of the steel nails in the previous batch in time.

[0003] However, due to the large slope and high position of the material conveying equipment, and the strong adhesion of the material, the existing compressed air blowing method cannot completely remove the soot on the surface of the steel nails. After the blowing is completed, the steel nails can only be cleaned one by one manually. This not only increases the labor intensity, but also poses a great safety hazard for the staff to climb high for cleaning operations, which seriously affects the production efficiency. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a steel nail cleaning device for material conveying equipment, which can solve the problem that the smoke stains on the surface of the steel nails cannot be completely removed by using compressed air blowing, and the steel nails need to be cleaned one by one manually, which not only increases the labor intensity, but also poses a great safety hazard when the staff have to climb high to perform the cleaning operation, which seriously affects the technical problem of production efficiency. At the same time, the present invention also provides a steel nail cleaning method for material conveying equipment, which is applied to the steel nail cleaning device for material conveying equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A steel nail cleaning device for material conveying equipment, comprising a supporting mechanism and a cleaning mechanism and a rotating mechanism arranged thereon, the supporting mechanism comprising a supporting plate and side guard plates I and II symmetrically arranged at the left and right ends of the supporting plate, the side guard plates I and II being fastened together by a reinforcing plate, the cleaning mechanism being located at the bottom of the supporting mechanism, the cleaning mechanism comprising a plurality of cleaning components staggeredly arranged on the surface of the supporting plate, the cleaning components comprising a roller shaft, a driving motor arranged at the top end of the roller shaft and a cleaning steel brush arranged and connected to the bottom end of the roller shaft, the driving motor being externally connected to a power source, the rotating mechanism suspending the supporting mechanism above a conveyor belt whose surface is uniformly covered with steel nails in a feeding bin of an external material conveying equipment, the rotating mechanism comprising a rotating cylinder connected to the side guard plate I through a transmission shaft I and a bearing seat connected to the side guard plate II through a transmission shaft II.

[0006] Furthermore, the top end of the roller shaft passes through the lower end surface of the support plate to the upper end surface of the support plate, and is connected to the driving motor located on the upper end surface of the support plate. The driving motor is fixedly connected to the upper end surface of the support plate through a motor base, and the bottom end of the roller shaft is fixedly connected to the cleaning steel brush located below the support plate.

[0007] Furthermore, the cleaning steel brush comprises a steel brush roller and a thin steel wire layer evenly arranged on the outer surface thereof.

[0008] Furthermore, the rotating cylinder and the bearing seat are respectively fastened to the top surfaces of the left and right side walls of the feed bin of the external material conveying equipment by bolts, and the rotating cylinder can drive the supporting mechanism to rotate up and down with the connection between the rotating cylinder and the transmission shaft I as the center.

[0009] Furthermore, the top outer side surface of the side guard plate I is connected to the transmission shaft I through a transmission key, and the top outer side surface of the side guard plate II is fastened to the transmission shaft II.

[0010] The present invention also provides a steel nail cleaning method for material conveying equipment, which is applied to the steel nail cleaning device for material conveying equipment, and the specific steps include: Step S1: Start the rotating cylinder so that the cleaning mechanism is located in the cleaning area An air source is introduced into the rotating cylinder to start the rotating cylinder. Under the cooperation of the bearing seat, the rotating cylinder can drive the supporting mechanism through the transmission shaft I and then drive the cleaning mechanism to move toward the conveyor belt of the material conveying equipment close to the outside, so that the supporting mechanism and the cleaning mechanism gradually enter the cleaning area until the bottom of the cleaning mechanism can be close to the steel nails on the surface of the conveyor belt to the greatest extent, so that the cleaning steel brush of the cleaning mechanism can be close to the outer surface of the steel nail and contact it; Step S2: Start the cleaning mechanism to clean the soot adhering to the surface of the steel nail The driving motor is started, and the driving motor can drive the cleaning steel brush to rotate through the roller shaft, so that the cleaning steel brushes in the plurality of cleaning components can rotate simultaneously and in the same direction. At the same time, the conveyor belt of the external material conveying equipment is started so that the steel nail can pass through the cleaning channel between the two adjacent cleaning steel brushes arranged in a front and rear offset manner, and under the action of the rotational friction between the cleaning steel brush and the surface of the steel nail, the soot adhered to the surface of one side of the steel nail can be cleaned by one of the cleaning steel brushes close to the steel nail first, and the soot adhered to the surface of the other side of the steel nail can be cleaned by another cleaning steel brush close to the steel nail as the conveyor belt moves, until all the steel nails are cleaned; Step S3: Close the cleaning mechanism and return it to its original position After the cleaning operation is completed, the drive motor is turned off so that the cleaning steel brush no longer moves. Subsequently, the rotating cylinder is started again, so that the rotating cylinder drives the supporting mechanism and the cleaning mechanism to rotate in the direction away from the conveyor belt, thereby causing the supporting mechanism and the cleaning mechanism to gradually leave the cleaning area so as to achieve the purpose of not affecting the subsequent normal conveying work of the external material conveying equipment.

It includes a support mechanism 1 and a cleaning mechanism 2 and a rotating mechanism arranged thereon. The support mechanism 1 includes a support plate 101 and side guard plates I 102 and II 103 symmetrically arranged at the left and right ends of the support plate 101. The side guard plates I 102 and II 103 are fastened together by a reinforcing plate 104. The cleaning mechanism 2 is located at the bottom of the support mechanism 1. The cleaning mechanism 2 includes a plurality of cleaning components staggeredly arranged on the surface of the support plate 101. The cleaning components include a roller 20 1. A driving motor 202 is arranged at the top of the roller 201 and a cleaning steel brush 203 is arranged and connected to the bottom of the roller 201. The driving motor 202 is externally connected to a power source. The rotating mechanism suspends the supporting mechanism 1 above the conveyor belt with steel nails uniformly distributed on the surface in the feeding bin of the external material conveying equipment. The rotating mechanism includes a rotating cylinder 302 connected to the side guard plate Ⅰ102 through a transmission shaft Ⅰ301 and a bearing seat 304 connected to the side guard plate Ⅱ103 through a transmission shaft Ⅱ303.

[0015] In the embodiment of the present invention, the support mechanism 1 is used to provide a stable support for the cleaning mechanism 2 .

[0016] In the embodiment of the present invention, the cleaning mechanism 2 can clean the soot adhered to the surface of the steel nails uniformly distributed on the conveyor belt of the external material conveying equipment. The support plate 101 has the function of providing support for the cleaning component. The top end of the roller 201 passes through the lower end surface of the support plate 101 to the upper end surface of the support plate 101, and is connected to the driving motor 202 located on the upper end surface of the support plate 101. The driving motor 202 is fixedly connected to the upper end surface of the support plate 101 through a motor base. The driving motor 202 has the function of providing driving force for the action of the cleaning component. The bottom end of the roller 201 is fixedly connected to the cleaning steel brush 203 located below the support plate 101. The driving motor 202 can drive the cleaning steel brush 203 to rotate through the roller 201, so that the cleaning steel brush 203 close to the steel nail can clean the soot adhered to the surface of the steel nail under its rotation. Specifically, the plurality of cleaning components are divided into two rows, and the two rows of cleaning components are arranged on the surface of the support plate 101 in a staggered manner. Accordingly, in the plurality of cleaning components, the plurality of cleaning steel brushes 203 are connected to the plurality of driving motors 202 corresponding to their number through the roller shaft 201, respectively, so that the plurality of cleaning steel brushes 203 can be arranged in a front-to-back staggered manner below the support plate 101, that is, one of the cleaning steel brushes 203 is located at the front end of the support plate 101, and the cleaning steel brush 203 arranged adjacent to it is located at its side and rear; the cleaning steel brush 203 and the steel nail are in a parallel intersection mode, that is, the cleaning steel brush 203 is exactly between two adjacent steel nails, and the front-to-back staggered manner A cleaning channel through which a steel nail can pass can be formed between two adjacent cleaning steel brushes 203, so that the soot adhered to the surface of one side of the steel nail can be cleaned by one of the cleaning steel brushes 203 close to the steel nail first, and the soot adhered to the surface of the other side of the steel nail can be cleaned by the other cleaning steel brush 203 close to the steel nail as the conveyor belt moves, so as to achieve the purpose of quickly cleaning the outer surface of the steel nail; the diameter of each cleaning steel brush 203 is larger than the distance between two adjacent steel nails, so that the cleaning steel brush 203 can have a larger contact area with the steel nail, so that the cleaning steel brush 203 can better clean the steel nail under high-speed rotation, thereby achieving the purpose of improving the cleaning effect.

[0017] In the embodiment described in the present invention, the cleaning steel brush 203 includes a steel brush roller and a fine steel wire layer evenly arranged on its outer surface. The arrangement of the fine steel wire layer ensures that the contact portion between the cleaning steel brush 203 and the steel nail has sufficient strength, is not prone to deformation, and is not prone to curling, which not only improves the cleaning effect, but also increases the service life of the cleaning steel brush 203.

[0018] In the embodiment described in the present invention, the rotating mechanism not only has the function of suspending the supporting mechanism 1 above the conveyor belt to facilitate cleaning of the soot adhered to the surface of the steel nails on the conveyor belt, but also can drive the supporting mechanism 1 and the cleaning mechanism 2 to enter or leave the cleaning area through the rotation action. The rotating cylinder 302 and the bearing seat 304 are respectively fastened to the top surfaces of the left and right side walls of the feeding bin of the external material conveying equipment by bolts. The rotating cylinder 302 has the function of providing a rotating power for the supporting mechanism 1. The rotating cylinder 302 can drive the supporting mechanism 1 to rotate the cylinder 302 and the conveyor. The connection of the moving shaft I 301 is a rotational movement up and down at the center of the circle, thereby achieving the purpose of driving the cleaning mechanism 2 to enter or leave the cleaning area. The bearing seat 304 can cooperate with the rotating cylinder 302 to ensure the smooth rotation of the supporting mechanism 1. At the same time, the bearing seat 304 can also limit the positions of the left and right ends of the cleaning mechanism 2 relative to the left and right ends of the conveyor belt, so that the cleaning mechanism 2 can accurately reach the cleaning area under the drive of the rotating cylinder 302, thereby making the cleaning channel between the two adjacent cleaning steel brushes 203 arranged in front and rear offset just face the moving direction of the steel nails on the surface of the conveyor belt; Specifically, the rotating cylinder 302 drives the supporting mechanism 1 and then drives the cleaning mechanism 2 to rotate in the direction close to the conveyor belt, so that the supporting mechanism 1 and the cleaning mechanism 2 gradually enter the cleaning area until the bottom of the cleaning mechanism 2 can be as close to the steel nails on the surface of the conveyor belt as possible, so that the cleaning steel brush 203 of the cleaning mechanism 2 can be close to the outer surface of the steel nail and contact it, so as to quickly and accurately clean the smoke stains adhering to the surface of the steel nail, so as to achieve the purpose of automated cleaning operation, help reduce labor intensity, avoid safety hazards caused by workers climbing up to perform cleaning operations, and seriously affect production efficiency; the rotating cylinder 302 drives the supporting mechanism 1 and then drives the cleaning mechanism 2 to rotate in the direction away from the conveyor belt, so that the supporting mechanism 1 and the cleaning mechanism 2 gradually leave the cleaning area so as not to affect the subsequent normal conveying work of the external material conveying equipment.

[0019] In the embodiment described in the present invention, the top outer side surface of the side guard plate I102 is connected to the transmission shaft I301 through a transmission key. The transmission key not only has the purpose of transmitting the rotational motion, but also can ensure the correct position and fixed relationship between the side guard plate I102 and the transmission shaft I301. The top outer side surface of the side guard plate II103 is fastened to the transmission shaft II303.

[0020] The present invention also provides a steel nail cleaning method for material conveying equipment, which is applied to the steel nail cleaning device for material conveying equipment, and the specific steps include: Step S1: Start the rotating cylinder 302 so that the cleaning mechanism 2 is located in the cleaning area An air source is introduced into the rotating cylinder 302 to start the rotating cylinder 302. Under the cooperation of the bearing seat 304, the rotating cylinder 302 can drive the supporting mechanism 1 and then drive the cleaning mechanism 2 to move toward the conveyor belt of the external material conveying equipment through the transmission shaft I 301, so that the supporting mechanism 1 and the cleaning mechanism 2 gradually enter the cleaning area until the bottom of the cleaning mechanism 2 can be as close to the steel nails on the surface of the conveyor belt as possible, so that the cleaning steel brush 203 of the cleaning mechanism 2 can be close to the outer surface of the steel nail and contact it; Step S2: Start the cleaning mechanism 2 to clean the soot adhering to the surface of the steel nail. The driving motor 202 is started. The driving motor 202 can drive the cleaning steel brush 203 to rotate through the roller 201, so that the cleaning steel brushes 203 in the plurality of cleaning components can all rotate simultaneously and in the same direction. At the same time, the conveyor belt of the external material conveying equipment is started so that the steel nail can pass through the cleaning channel between the two adjacent cleaning steel brushes 203 arranged in a front and rear offset manner. Under the action of the rotational friction between the cleaning steel brush 203 and the surface of the steel nail, the soot adhered to the surface of one side of the steel nail can be first cleaned by one of the cleaning steel brushes 203 close to the steel nail, and the soot adhered to the surface of the other side of the steel nail can be cleaned by another cleaning steel brush 203 close to the steel nail as the conveyor belt moves, until all the steel nails are cleaned; Step S3: Close the cleaning mechanism 2 and return the cleaning mechanism 2 to its original position. After the cleaning operation is completed, the driving motor 202 is turned off so that the cleaning steel brush 203 no longer moves. Subsequently, the rotating cylinder 302 is started again, so that the rotating cylinder 302 drives the supporting mechanism 1 and the cleaning mechanism 2 to rotate in a direction away from the conveyor belt, thereby causing the supporting mechanism 1 and the cleaning mechanism 2 to gradually leave the cleaning area so as to achieve the purpose of not affecting the subsequent normal conveying work of the external material conveying equipment.
