Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to an arc-shaped full-fitting buffer device and conveying equipment. Background Art

[0002] In the belt conveyor of the material conveying system, the buffer device includes two types: buffer roller group and slide type buffer device. The main characteristics of the buffer roller group are low manufacturing cost and simple processing. However, with the emergence of belt conveyors with long distance, high belt speed, high transport volume and super-large specifications, the buffer roller group has many shortcomings in use, mainly manifested in: 1. The contact area between the buffer roller and the belt is small, and the buffering capacity of the buffer roller is poor. It cannot effectively absorb the impact force when the material falls, which makes the buffer roller easy to break and fall off, thereby causing the conveyor belt to tear longitudinally.

[0003] 2. The distance between the buffer roller groups is large, and the two groups of buffer rollers are suspended. Sharp hard objects in the material can easily insert into the conveyor belt between the two groups of buffer rollers, causing longitudinal tearing of the conveyor belt.

[0004] 3. When the buffer roller group is overloaded, the conveyor belt between the two groups of buffer rollers will sink, making the conveyor belt in the blanking section wavy. The anti-overflow skirt on the guide trough cannot be in full contact with the tape, resulting in poor sealing of the blanking section and material overflow that pollutes the working environment.

[0005] 4. Long-term operation of the conveyor belt causes materials to easily adhere to the surface of the buffer roller, increasing the wear of the belt, and in severe cases even causing the belt to deviate.

[0006] 5. The rotating bearing inside the buffer roller is impacted by the material for a long time, and the bearing and seal are easily damaged, which causes the roller to rotate inflexibly or stop rotating, and the sliding friction between the belt and the roller changes to static friction, which affects the service life during transportation. The buffer roller may also jump out of the roller frame under the impact of the material, making it impossible to return to its original position.

[0007] The slider type buffer device is composed of a buffer strip and a bracket, and the buffer strip plays a buffering role. The slider type buffer device also has the following shortcomings in application: 1. When the sliding bar type buffer device is working, there is a blind area without contact between the angle between the buffer bars on both sides and the middle buffer bar and the conveyor belt, which increases the probability of the conveyor belt being penetrated by sharp objects or sharp materials, thereby increasing the risk of longitudinal tearing of the conveyor belt.

[0008] 2. Under the working conditions of high belt speed, high drop and large pieces of materials, the slide-type buffer device cannot fully and effectively absorb the impact force when the materials fall, causing a huge impact on the conveyor belt when the materials fall, shortening the service life of the conveyor belt.

[0009] 3. The buffer strips in the sliding buffer device are arranged equidistantly. Since there is a certain gap between the side buffer strips, there is a risk that the conveyor belt will get stuck in the gaps between the buffer strips during operation. Once stuck, the wear between the buffer strips and the conveyor belt will be aggravated, affecting the service life of each other.

[0010] 4. Since the buffer strips in the slide type buffer device are mostly fastened with bolts, when replacing the buffer strips, due to the harsh working environment, the connecting bolts are not easy to remove, which increases the labor intensity and maintenance time of the workers and reduces the work efficiency of the workers.

[0011] Therefore, it is necessary to develop a buffering solution that can cope with larger impacts. Summary of the invention

[0033] In the belt conveyor of the material conveying system, the buffer device includes two types: buffer roller group and slide type buffer device. The main characteristics of the buffer roller group are low manufacturing cost and simple processing. However, with the emergence of belt conveyors with long distance, high belt speed, high transport volume and super-large specifications, the buffer roller group has many shortcomings in use, mainly manifested in: 1. The contact area between the buffer roller and the belt is small, and the buffering capacity of the buffer roller is poor. It cannot effectively absorb the impact force when the material falls, which makes the buffer roller easy to break and fall off, thereby causing the conveyor belt to tear longitudinally.

[0034] 2. The distance between the buffer roller groups is large, and the two groups of buffer rollers are suspended. Sharp hard objects in the material can easily insert into the conveyor belt between the two groups of buffer rollers, causing longitudinal tearing of the conveyor belt.

[0035] 3. When the buffer roller group is overloaded, the conveyor belt between the two groups of buffer rollers will sink, making the conveyor belt in the blanking section wavy. The anti-overflow skirt on the guide trough cannot be in full contact with the tape, resulting in poor sealing of the blanking section and material overflow that pollutes the working environment.

[0036] 4. Long-term operation of the conveyor belt causes materials to easily adhere to the surface of the buffer roller, increasing the wear of the belt, and in severe cases even causing the belt to deviate.

[0037] 5. The rotating bearing inside the buffer roller is impacted by the material for a long time, and the bearing and seal are easily damaged, which causes the roller to rotate inflexibly or stop rotating, and the sliding friction between the belt and the roller changes to static friction, which affects the service life during transportation. The buffer roller may also jump out of the roller frame under the impact of the material, making it impossible to return to its original position.

[0038] The slider type buffer device is composed of a buffer strip and a bracket, and the buffer strip plays a buffering role. The slider type buffer device also has the following shortcomings in application: 1. When the sliding bar type buffer device is working, there is a blind area without contact between the angle between the buffer bars on both sides and the middle buffer bar and the conveyor belt, which increases the probability of the conveyor belt being penetrated by sharp objects or sharp materials, thereby increasing the risk of longitudinal tearing of the conveyor belt.

[0039] 2. Under the working conditions of high belt speed, high drop and large pieces of materials, the slide-type buffer device cannot fully and effectively absorb the impact force when the materials fall, causing a huge impact on the conveyor belt when the materials fall, shortening the service life of the conveyor belt.

[0040] 3. The buffer strips in the sliding buffer device are arranged equidistantly. Since there is a certain gap between the side buffer strips, there is a risk that the conveyor belt will get stuck in the gaps between the buffer strips during operation. Once stuck, the wear between the buffer strips and the conveyor belt will be aggravated, affecting the service life of each other.

[0041] 4. Since the buffer strips in the slide type buffer device are mostly fastened with bolts, when replacing the buffer strips, due to the harsh working environment, the connecting bolts are not easy to remove, which increases the labor intensity and maintenance time of the workers and reduces the work efficiency of the workers.

[0042] To this end, the present invention provides an arc-shaped full-fitting buffer device, which can solve the problem of non-fitting with the conveyor belt, thereby improving the impact resistance and being able to cope with larger impact forces.

[0043] Reference Figures 1 to 5 , an arc-shaped full-fitting buffer device according to an embodiment of the present invention comprises: A base 100, wherein an arc-shaped rail 101 is disposed at the upper end of the base 100; A plurality of buffer blocks 200 are provided with a slot 2021 adapted to the arc-shaped rail 101 , and the buffer blocks 200 are slidably arranged on the arc-shaped rail 101 .

[0044] The locking portion 300 is disposed on the base 100 or the buffer block 200 and is used to fix the buffer block 200 on the arc-shaped rail 101 .

[0045] The arc-shaped full-fitting buffer device in the present application is provided with an arc-shaped rail 101 on the base 100, and the buffer block 200 is slidably installed on the arc-shaped rail 101 and is locked and fixed by the locking part 300. Therefore, the upper end of the buffer block 200 can form an arc-shaped supporting surface. Under the action of the gravity of the belt material, it can fully fit the conveyor belt along the width direction of the conveyor belt, avoiding the risk of puncture and tearing due to a gap between the conveyor belt and the buffer device.

[0046] Therefore, the arc-shaped full-fitting buffer device in the present application can solve the problem of non-fitting with the conveyor belt, thereby improving the impact resistance and being able to cope with larger impact forces.

[0047] Since the buffer block 200 is slidably disposed on the arc-shaped rail 101 by utilizing the slot 2021 , it can be taken out from the end of the arc-shaped rail 101 or a set position, so that it is convenient to replace.

[0048] The locking portion 300 can only lock the buffer blocks 200 at both ends, using the buffer blocks 200 at both ends to clamp and fix the middle buffer block 200, or can lock each buffer block 200 individually. Technical personnel in this field can flexibly set it according to needs.

[0049] Reference Figure 4 In some embodiments of the present invention, the buffer block 200 includes: The buffer portion 201 is made of elastic material or has an elastic structure; The clamping portion 202 is disposed at the bottom of the buffer portion 201 . The clamping portion 202 is a rigid structure. The clamping slot 2021 is provided in the clamping portion 202 .

[0050] Since the buffer device is mainly arranged at the position of the material discharge chute to withstand the impact of the material, the present embodiment can effectively cope with the impact of the material by arranging the buffer portion 201. At the same time, the card slot 2021 is arranged on the clamping portion 202 to ensure the installation stability of the buffer block 200 on the arc-shaped card rail 101, and prevent the buffer block 200 from being disengaged or offset from the arc-shaped card rail 101 under the impact of the material.

[0051] When the buffer part 201 is made of elastic material, it can achieve the function of buffering and absorbing energy by using its own material properties. When the buffer part 201 is set as an elastic structure, it can deal with material impact by setting springs and other buffering and absorbing designs.

[0052] In some embodiments of the present invention, the clamping portion 202 is an aluminum alloy structure, and the buffer portion 201 is a rubber structure. The aluminum alloy structure can ensure the sliding fit stability between the clamping slot 2021 and the arc-shaped clamping rail 101, and also has the advantage of being lightweight, which is conducive to reducing the overall weight. The buffer portion 201 is set to a rubber structure, which can ensure the service life and has excellent buffering performance.

[0053] Reference Figure 4 In some embodiments of the present invention, a support portion 203 is provided at the upper end of the buffer block 200, and the support portion 203 is a rigid structure. It is understandable that since the buffer device is provided below the conveyor belt to support the conveyor belt, and the conveyor belt is made of rubber material, if the conveyor belt directly abuts against the buffer portion 201, it will cause a large friction force. This embodiment can effectively support the conveyor belt and reduce the friction force by providing a rigid support portion 203.

[0054] In some embodiments of the present invention, the support portion 203 is a polyurethane structure. Since the polyurethane material has a self-lubricating effect and takes both rigidity and elasticity into consideration, it can effectively cope with the impact of materials and support the conveyor belt.

[0055] Reference Figure 3 In some embodiments of the present invention, the base 100 is provided with mounting seats 102 at both ends of the arc-shaped rail 101, the locking portion 300 is detachably connected to the mounting seats 102, and the locking portion 300 is pressed against the outer side of the buffer block 200. The structural setting of this embodiment, i.e., the locking portion 300 is used to clamp from both ends of all the buffer blocks 200, is easy to install, and is convenient for disassembly, assembly and replacement of the buffer blocks 200.

[0056] Moreover, generally the arc-shaped rail 101 is arranged along the width direction of the conveyor belt, and the two ends of the buffer block 200 are located on both sides of the width direction of the conveyor belt. Therefore, the mounting seat 102 of this embodiment is located on both sides of the conveyor belt, which is convenient for disassembly and assembly, and workers do not need to operate from the bottom of the conveyor belt, which is convenient for disassembly and assembly.

[0057] In some embodiments of the present invention, the locking portion 300 is connected to the mounting base 102 by bolts.

[0058] In some embodiments of the present invention, a plurality of gaskets are provided between the locking portion 300 and the mounting seat 102. In this embodiment, the spacing between the locking portion 300 and the mounting seat 102 is adjusted by providing gaskets, which facilitates adjustment according to actual clamping conditions and has greater flexibility.

[0059] In some embodiments of the present invention, the base 100 is provided with a plurality of arc-shaped rails 101 in parallel, and the buffer block 200 is provided with a plurality of slots 2021 and is slidably connected to the plurality of arc-shaped rails 101. It can be understood that the buffer block 200 in this embodiment extends along the length direction of the conveyor belt and is supported by the plurality of arc-shaped rails 101, which can effectively improve the structural strength and the support strength of the conveyor belt.

[0060] The present invention further provides a conveying device, which includes the arc-shaped full-fitting buffer device of any of the above embodiments.

[0061] It can be understood that the conveying equipment in the present application, by setting an arc-shaped rail 101 on the base 100, the buffer block 200 is slidably installed on the arc-shaped rail 101, and is locked and fixed by the locking part 300, so that the upper end of the buffer block 200 can form an arc-shaped supporting surface, and under the action of gravity of the material, it can completely fit the conveyor belt along the width direction of the conveyor belt, avoiding the risk of puncture and tearing due to a gap between the conveyor belt and the buffer device, and can solve the problem of non-fitting with the conveyor belt, thereby improving the impact resistance and being able to cope with larger impact forces.

[0062] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
