[0023] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 2 As shown, a flexible buffer belt conveyor includes a body 1, a belt 2, a buffer device 3, and a guard plate 5.

[0025] Legs 12 are fixedly connected to both sides of the bottom of the body 1 , and connecting columns 13 are fixedly arranged between the legs 12 to ensure the stability of the device body 1 .

[0026] Redirecting rollers 11 are rotatably provided at the head and tail ends of the fuselage 1, and the belt 2 is tensioned between the redirecting rollers 11 so that the belt 2 is set on the fuselage 1, and a driving device 4 is provided in the middle of the fuselage 1, and the driving device 4 drives the belt 2 to rotate around the fuselage 1 for conveying packages.

[0027] The two ends of the redirecting roller 11 are in a cone shape, so that the belt tensioned on the redirecting roller 11 can avoid deviation to the left or right under the action of the cone surfaces at the two ends of the redirecting roller.

[0028] The buffer device 3 is arranged on the body 1, and is used to mitigate the impact and collision generated when the package falls onto the belt 2. Specifically, the buffer device 3 includes a plurality of buffer rollers 31, an elastic component 32, a guide column 33, and a fixed seat 34. The buffer rollers 31 are arranged on the body 1 at equal intervals along the conveying direction of the package, and the side wall of the body 1 is provided with a plurality of strip grooves 12 along the conveying direction of the package. The ends of the buffer rollers 31 are slidably matched with the strip grooves 12, so that the upper bottom surface of the belt 2 is supported by the plurality of buffer rollers 31, so that the buffer rollers 31 provide support to the surface of the belt 2, and the fixed seats 34 are a pair and are symmetrically arranged on both sides of the body 1, and the guide columns 33 are arranged on the two sides of the body 1. The column 33 is fixed on the fixing seat 34, the end of the buffer roller 31 has a guide hole 331 which cooperates with the guide column 33, and the elastic component 32 is arranged between the fixing seat 34 and the end of the buffer roller 31. When there is no package on the belt, the elastic component 32 supports the buffer roller 31. When the package falls onto the belt, the buffer roller 31 overcomes the elastic force of the elastic component 32 under the external force generated when the package falls, so that the buffer roller 31 compresses the elastic component 32 and slowly descends, effectively reducing the impact and collision caused by the package falling on the belt.

[0029] In order to solve the problem of insufficient elastic force of the spring component after long-term use, a strip hole is provided on the side wall of the fuselage corresponding to the fixing seat 34 in this embodiment, and the height of the fixing seat 34 can be adjusted through the strip hole to shorten the distance between the fixing seat and the buffer roller, thereby solving the problem of insufficient elastic force of the spring component 32 between the fixing seat and the buffer roller 31 and reducing the number of times the spring is replaced.

[0030] In another embodiment, an adjustment component is provided at the lower end of the elastic component 32. The adjustment component of this embodiment can adopt a gasket, an adjustment nut, etc. to adjust the length of the elastic component, thereby increasing the elastic force of the elastic component and reducing the number of times the spring is replaced.

[0031] A plurality of rollers 6 are arranged below the buffer drum 31 . The rollers 6 are arranged on the fuselage 1 along the conveying direction of the package so that the rollers 6 hold the lower surface of the belt 2 to support the belt, thereby improving the stability of the belt conveying.

[0032] The guard plates 5 are a pair and are symmetrically arranged above both sides of the belt 2 and fixedly connected to the fuselage 1. The width between the guard plates 5 is smaller than the width of the belt 2, thereby closing the gap between the belt 2 and the buffer roller 31, thereby avoiding the situation where packages or hands are pinched between the belt 2 and the fuselage 1, and at the same time preventing the belt from deviating.

[0033] The driving device 4 includes a driving shaft, a tensioning roller 42, and a tensioning adjustment mechanism 43. The driving shaft is rotatably arranged in the fuselage 1. In this embodiment, a conveying driving device is fixedly installed in the fuselage 1. The conveying driving device preferably adopts a motor, and its output shaft and the driving shaft are connected by a synchronous belt transmission, so that the driving shaft is driven to rotate by the conveying driving device, thereby driving the belt 2 to rotate to transport the package. The tensioning roller 42 is slidably arranged between the driving shaft and the buffer roller 31, and the tensioning adjustment mechanism 43 is arranged on the side wall of the fuselage, which is used to adjust the tension of the belt 2 to ensure the stability of the belt 2 transmission.

[0034] The tensioning adjustment mechanism 43 includes an adjusting rod 431, and a slot 421 is provided at the end of the tensioning roller 42. The adjusting rod 431 passes through the slot 421 and is rotatably connected to the side wall of the fuselage 1, and a limiting member 432 is respectively provided on both sides of the slot 421 in the middle of the adjusting rod 431. In this embodiment, the adjusting rod is preferably a screw rod, and the limiting member is preferably a nut, so that the limiting member is threadedly connected to the adjusting rod, and the limiting member 432 is moved close to each other by rotating the limiting member 432, so that the end of the tensioning roller 42 is limited to the middle of the adjusting rod, so that the tension of the belt 2 is adjusted by rotating the adjusting rod 431 to link the tensioning roller 42 to move horizontally.

[0035] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model.
