Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a belt conveyor with a C-shaped deep groove angle. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food. Currently, to achieve large-angle conveying close to the material's angle of repose, ordinary belt conveyors need to replace the smooth surface of the conveyor belt with a patterned belt. However, using patterned belts results in drawbacks such as high vibration, short lifespan of the conveyor belt and idlers, and difficulty in cleaning, as well as dust generation. While tubular belt conveyors can solve these problems, their use results in high lateral stiffness resistance of the belt, high operating energy consumption, and the need for specialized belts, leading to high manufacturing costs.

[0003] Therefore, those skilled in the art urgently need to develop a belt conveyor with a C-shaped deep groove angle to solve the above-mentioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a C-shaped deep trough angle belt conveyor. By changing the structural form of the carrying idler group, the conveyor belt is formed into a new trough shape, which can break through the maximum inclination angle for safe material conveying of ordinary conveyor belts (smooth surface conveyor belts) and achieve large inclination angle conveying close to the material's angle of repose. This solves the disadvantages of using patterned belts for large inclination angle material conveying, such as large vibration, low life of conveyor belts and idlers, and incomplete cleaning. It also overcomes the technical problems of high rigidity resistance, high operating energy consumption, and high manufacturing cost of using special belts in tubular belt conveyors.

[0005] To achieve the above objectives, the present invention is implemented according to the following technical solution:

[0006] A C-shaped deep-groove belt conveyor includes a frame, a conveyor belt, and a return idler assembly disposed at the lower part of the frame. A drive roller and a redirecting roller are respectively disposed at both ends of the frame. The conveyor belt is driven and connected to the drive roller and the redirecting roller, and the conveyor belt is a smooth, ordinary conveyor belt. It also includes a C-shaped deep-groove idler assembly disposed at the upper part of the frame. The return section of the conveyor belt is supported on the return idler assembly, and the feeding section of the conveyor belt is supported on the C-shaped deep-groove idler assembly. The C-shaped deep-groove idler assembly includes an upper idler frame and a first idler assembly rotatably connected to the front side of the upper idler frame. The first idler group includes a right vertical roller, a left upper roller, and a left lower roller, with the left upper roller and the left lower roller arranged symmetrically in a figure-eight shape. The second idler group includes a left vertical roller, a right upper roller, and a right lower roller, with the right upper roller and the right lower roller arranged symmetrically in a figure-eight shape. The axes of the left upper roller and the right lower roller are at an angle of 30 degrees to the horizontal plane. The right vertical roller and the left vertical roller are vertically arranged on the left and right sides of the conveyor belt. The cross-section of the conveyor belt is formed into an upward-opening C-shaped deep groove under the combined action of the first idler group and the second idler group.

[0007] Preferably, the upper roller frame is fixedly connected to the machine frame, and the upper roller frame is a rectangular plate structure with an octagonal inner hole in the middle. The opposite sides of the octagonal inner hole are parallel to each other, and the left and right sides are vertically arranged, which facilitates the installation and positioning of the first roller group and the second roller group.

[0008] Preferably, the drive roller is connected to a geared motor.

[0009] Preferably, the return idler group includes a plurality of horizontal idlers evenly distributed along the return section of the conveyor belt.

[0010] Preferably, the notch width of the C-shaped deep groove is 20-100mm, and more preferably, the notch width of the C-shaped deep groove is 50mm. This arrangement makes the notch width relatively small, which is convenient for observing the state of the conveyed material and also helps to suppress dust generated during the material conveying process.

[0011] This invention also includes other components that enable its normal operation, all of which employ conventional techniques in the art. Furthermore, devices and components not limited in this invention employ conventional techniques in the art, such as frames, return roller assemblies, conveyor belts, drive rollers, redirecting rollers, and geared motors. In specific implementations, those skilled in the art can select appropriate equipment or component models according to specific working scenarios. Additionally, the right vertical roller, upper left roller, lower left roller, left vertical roller, upper right roller, and lower right roller in this application are all ordinary conveyor rollers.

[0012] The working principle of this invention is as follows: The single-set C-type deep groove angle idler group of this application consists of 6 idlers. Below the conveyor belt, there are 2 sets of idlers at a 30-degree angle to the horizontal (including the lower left and lower right rollers); on both sides, there are idlers at a 90-degree angle to the horizontal (including the left and right vertical rollers); and above, there are 2 sets of idlers at a 30-degree angle to the horizontal (including the upper left and upper right rollers). These 6 idlers are arranged in a 3-3 configuration. In this way, the conveyor belt, supported by the two sets of idlers below, can generate sufficient load-bearing capacity; the vertical idlers on the left and right sides allow the conveyor belt to be better extruded and shaped, meeting the appropriate extrusion pressure on the material, thereby increasing the mechanical interlock between adjacent blocky materials and achieving the purpose of increasing the conveying inclination angle; the inclined design of the two sets of idlers above allows for adjustment of the size of the gap formed at the joint of the conveyor belt as needed, ensuring sufficient extension space for the conveyor belt at the joint to reduce conveying resistance.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention utilizes traditional idlers and ordinary flat conveyor belts, but by redesigning the structural form of the load-bearing cross-section, it can achieve large-angle conveying close to the material's angle of repose. Compared with the patterned belts used in traditional large-angle conveyors, it offers significant economic benefits, effectively extends the service life of the large-angle conveyor belt and idler assembly, reduces vibration during transportation, and improves cleaning capabilities.

[0015] 2. Compared with ordinary 35-degree trough angle conveyors, the present invention can realize material conveying at a larger angle and can effectively reduce dust generation during the conveying process.

[0016] 3. Compared with tube conveyors, this invention can effectively reduce the lateral stiffness resistance of the conveyor belt during the conveying process, save energy and reduce consumption, and effectively reduce the cost of special conveyor belts.

[0017] In summary, this invention solves the problems of low lifespan, high vibration, and difficulty in cleaning of patterned conveyor belts without the need for patterned conveyor belts or special tapes for tubular conveyors, while also reducing the high cost associated with special tapes for tubular conveyors.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example

[0022] This embodiment proposes a C-shaped deep trough angle belt conveyor. By changing the structural form of the carrying idler group, the conveyor belt is formed into a new trough shape, which can break through the maximum inclination angle for safe material conveying of ordinary conveyor belts (smooth surface conveyor belts) and achieve large inclination angle conveying close to the material's angle of repose. This solves the disadvantages of using patterned belts for large inclination angle material conveying, such as large vibration, low conveyor belt and idler life, and incomplete cleaning. It also overcomes the technical problems of high rigidity resistance, high operating energy consumption, and high manufacturing cost of using special belts when using tubular belt conveyors.

[0023] To achieve the above objectives, the present invention is implemented according to the following technical solution:

[0024] like Figures 1-2 As shown, a C-shaped deep groove angle belt conveyor includes a frame 1, a conveyor belt 2, and a return idler group 3 disposed at the lower part of the frame. A drive roller (not shown) and a redirecting roller (not shown) are respectively disposed at both ends of the frame. The conveyor belt is driven and connected to the drive roller and the redirecting roller, and the conveyor belt is a smooth, ordinary conveyor belt. It also includes a C-shaped deep groove angle idler group 4 disposed at the upper part of the frame. The return section of the conveyor belt is supported on the return idler group, and the feeding section of the conveyor belt is supported on the C-shaped deep groove angle idler group. The C-shaped deep groove angle idler group includes an upper idler frame 41 and a roller rotatably connected to the front side of the upper idler frame. The conveyor belt consists of a first idler group and a second idler group rotatably connected to the rear side of the upper idler frame. The first idler group includes a right vertical roller 42, a left upper roller 43, and a left lower roller 44, with the left upper roller and left lower roller arranged symmetrically in a figure-eight shape. The second idler group includes a left vertical roller 45, a right upper roller 46, and a right lower roller 47, with the right upper roller and right lower roller arranged symmetrically in a figure-eight shape. The axes of the left upper roller and right lower roller are at an angle of 30 degrees to the horizontal plane. The right vertical roller and left vertical roller are vertically arranged on the left and right sides of the conveyor belt. The cross-section of the conveyor belt is formed into an upward-opening C-shaped deep groove under the combined action of the first idler group and the second idler group.

[0025] Specifically, the upper roller frame is fixedly connected to the machine frame, and the upper roller frame is a rectangular plate structure with an octagonal inner hole in the middle. The opposite sides of the octagonal inner hole are parallel to each other, and the left and right sides are vertically arranged, which facilitates the installation and positioning of the first roller group and the second roller group.

[0026] In this embodiment, the drive roller is connected to a geared motor, and the return idler group includes several horizontal idlers evenly distributed along the return section of the conveyor belt.

[0027] More specifically, the notch width of the C-shaped deep groove is 50mm. This arrangement makes the notch width relatively small, which facilitates observation of the conveyed material status and helps to suppress dust generated during the material conveying process.

[0028] The working principle of this invention is as follows: The single-set C-type deep groove angle idler group of this application consists of 6 idlers. Below the conveyor belt, there are 2 sets of idlers at a 30-degree angle to the horizontal (including the lower left and lower right rollers); on both sides, there are idlers at a 90-degree angle to the horizontal (including the left and right vertical rollers); and above, there are 2 sets of idlers at a 30-degree angle to the horizontal (including the upper left and upper right rollers). These 6 idlers are arranged in a 3-3 configuration. In this way, the conveyor belt, supported by the two sets of idlers below, can generate sufficient load-bearing capacity; the vertical idlers on the left and right sides allow the conveyor belt to be better extruded and shaped, meeting the appropriate extrusion pressure on the material, thereby increasing the mechanical interlock between adjacent blocky materials and achieving the purpose of increasing the conveying inclination angle; the inclined design of the two sets of idlers above allows for adjustment of the size of the gap formed at the joint of the conveyor belt as needed, ensuring sufficient extension space for the conveyor belt at the joint to reduce conveying resistance.

[0029] The technical solutions of the present invention are not limited to the specific embodiments described above. Any technical modifications made in accordance with the technical solutions of the present invention fall within the protection scope of the present invention.
