Description

Technical Field

[0001] The invention relates to the field of conveying equipment, and in particular to a telescopic belt conveyor for a storage center. Background Art

[0002] Warehousing centers are the core of modern logistics systems. They are mainly responsible for storing and managing goods until they are shipped to retailers, wholesalers or end consumers. Goods in warehousing centers are frequently transported in and out of warehouses, and goods need to be transported frequently by trucks.

[0003] The telescopic belt conveyor can go deep into the truck and automatically transport the goods from the truck to the warehouse, greatly shortening the distance of manual material handling, shortening the loading and unloading time, reducing labor intensity, reducing damage to goods, reducing loading and unloading costs, and improving work efficiency. The telescopic belt conveyor adds a telescopic mechanism to the ordinary belt conveyor, allowing the belt conveyor to freely extend and retract in the length direction. The user can adjust the button according to their own requirements and control the length of the conveyor at any time.

[0004] When the existing telescopic belt conveyor is not in use, the belt is also in a taut state. If the belt is kept in a taut state for a long time, the internal stress will continue to act on the belt material, resulting in fatigue accumulation of the material. This accumulated fatigue may reduce the service life of the belt. And after the front end of the telescopic belt conveyor is extended, the support point gradually moves away, so the weight of the goods that can be supported by the front end is limited. Therefore, those skilled in the art provide a telescopic belt conveyor for a storage center to solve the problems raised in the above background technology. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 12 In this embodiment, a telescopic belt conveyor for a storage center is provided, comprising a base 1, the base 1 comprising a frame 11, a body mechanism 2 is installed above the frame 11, a sliding mechanism 3 is slidably connected to the front end of the body mechanism 2, a conveying roller 1 25, a conveying roller 26, a conveying roller 3 27 and a conveying roller 4 28 are installed inside the body mechanism 2, a conveying roller 5 33 and a conveying roller 6 34 are installed inside the sliding mechanism 3, and the outer side of the conveying roller is covered with a conveyor belt, wherein the conveying roller 5 33 and the conveying roller 4 28 have different horizontal heights;

[0039] A rotatable supporting mechanism 4 is installed at the front end of the sliding mechanism 3 , and the supporting mechanism 4 includes a rotating rod 42 with an adjustable angle and a bottom plate 43 .

[0040] When not in use, the telescopic belt conveyor remains in a shortened state, with the sliding mechanism 3 inside the body mechanism 2. When loading and unloading goods, the sliding mechanism 3 extends from the inside of the body mechanism 2, and the front end of the sliding mechanism 3 extends into the interior of the carriage, so that the goods inside the carriage can be transported by the extended conveyor belt.

[0041] When the sliding mechanism 3 is extended into the interior of the car, it is supported by the supporting mechanism 4. During the extension process of the sliding mechanism 3, the rotating rod 42 and the bottom plate 43 can swing, so that they remain vertically downward under the influence of gravity, so that the bottom plate 43 can be in contact with the interior of the car in parallel and provide firm support for the extended part of the sliding mechanism 3.

[0042] In further embodiments, see Figures 1-2 The body mechanism 2 includes a fixed frame 21, and the sliding mechanism 3 includes a sliding frame 31. The fixed frame 21 is fixedly connected with a support frame 1 23, and the sliding frame 31 is slidably connected to the support frame 1 23. The fixed frame 21 is fixedly connected with a support frame 24 on one side of the support frame 1 23, and the support frame 2 24 is fixedly installed with a telescopic rod 22, and one end of the telescopic rod 22 is connected to the sliding frame 31.

[0043] By extending the telescopic rod 22, one end of the telescopic rod 22 pushes the sliding frame 31 to move to one side, and one end of the sliding frame 31 extends from the inside of the fixed frame 21. The sliding frame 31 is limited and supported by the support frame 1 23 to ensure that the sliding frame 31 slides stably inside the fixed frame 21.

[0044] In further embodiments, see Figures 2 to 9 The conveying roller 1 25, the conveying roller 26, the conveying roller 3 27 and the conveying roller 4 28 are all installed inside the fixed frame 21, the conveying roller 5 33 and the conveying roller 6 34 are all installed inside the sliding frame 31, the conveying roller 1 25 is installed at one end of the fixed frame 21, the conveying roller 6 34 is installed inside the sliding frame 31 away from the conveying roller 1 25, the conveying roller 6 34 and the conveying roller 1 25 are located at the same horizontal height, the conveying roller 5 33 is located at the other end of the sliding frame 31, the conveying roller 5 33 is located below the conveying roller 6 34, the conveying roller 2 26 and the conveying roller 4 28 are located on both sides of the bottom end inside the fixed frame 21, the conveying roller 4 28 is located below the sliding frame 31, the conveying roller 3 27 is installed at the lower end of the fixed frame 21, and one end of the conveying roller 3 27 is connected to a driving mechanism.

[0045] The conveying roller three 27 is driven to rotate by the driving mechanism, and the conveying roller three 27 thereby drives the belt to rotate and convey.

[0046] After the sliding frame 31 is extended, the length of the belt surrounding the outer sides of the plurality of conveying rollers needs to be lengthened, and the belt is stretched, thereby increasing the tension between the belt and the plurality of conveying rollers. Figure 8 and Fig. 9The figure is a schematic diagram of the belt before and after conveying. After the sliding frame 31 is extended, the positions of the conveying roller 5 33 and the conveying roller 6 34 change (the positions of other conveying rollers remain unchanged), where L1 is the length of the belt between the conveying roller 5 33 and the conveying roller 4 28 in the contracted state, L3 is the length of the belt between the conveying roller 5 33 and the conveying roller 4 28 in the extended state, and L2 is the increased length of the belt after the conveying roller 6 34 is extended (that is, the distance the conveying roller 5 33 moves). That is, the length that needs to be changed from L1 to L3 is sufficient to satisfy the distance of L2 that the conveying roller 5 33 moves. Fig. 9 In contrast, the sum of the two sides of the triangle is greater than the third side, and the sum of the lengths of L2 and L3 is greater than L1. The length of L3 converted from L1 cannot satisfy the distance of L2 for the conveying roller 5 33 to move. Therefore, the belt itself needs to be stretched, so that the tension between the belt and the conveying roller also increases.

[0047] That is, when the belt between the conveyor roller five 33 and the conveyor roller four 28 is in an inclined state (the belt between the conveyor roller five 33 and the conveyor roller four 28 in the existing telescopic belt conveyor is in a horizontal state, ensuring that the shortened part L1 is L2), after the sliding frame 31 is extended, the belt needs to be tensioned.

[0048] In further embodiments, see Fig.10 The conveying roller six 34 is movably installed at one end of the sliding frame 31, and a moving rail 341 is fixedly connected inside one end of the sliding frame 31. A moving seat 342 is slidably connected to the moving rail 341, and the conveying roller six 34 is installed on the moving seat 342.

[0049] The belt of the telescopic belt conveyor needs to be tensioned after being extended, so that the belt will pull the movable seat 342 to move away from the front end of the sliding frame 31, thereby avoiding excessive belt tension and severe wear.

[0050] In further embodiments, see Fig.12 The conveying roller 25 is slidably connected to the fixed frame 21, and moving rods 251 are provided at both ends of the conveying roller 25. The moving rod 251 is slidably connected to the fixed frame 21. A telescopic rod 3 252 is installed at one end of the fixed frame 21. The upper end of the telescopic rod 3 252 is fixedly connected to a limiting block 253. The upper end of the limiting block 253 is inserted between the moving rod 251 and the fixed frame 21, and the side of the limiting block 253 that contacts the moving rod 251 is an inclined surface.

[0051] By extending or shortening the telescopic rod three 252, the telescopic rod three 252 drives the limit block 253 to rise or fall, and the limit block 253 can adjust the distance between the moving rod 251 and the fixed frame 21, thereby adjusting the distance between the conveying roller 1 25 at one end of the moving rod 251 and the fixed frame 21, thereby changing the tension of the belt, avoiding excessive belt tension and severe wear after extension and retraction, or keeping the belt in a tensioned state when not extended and able to be used.

[0052] In further embodiments, see Fig.11 The supporting mechanism 4 includes a fixed rod 41, which is fixedly connected to the inside of the sliding frame 31. A rotating rod 42 is rotatably connected to the fixed rod 41. The lower end of the rotating rod 42 is connected to the bottom plate 43. One side of the upper end of the rotating rod 42 is fixedly connected to a tooth plate 1 44. Tooth plate 2 45 is slidably connected to both ends of the fixed rod 41. A spring 46 is provided between tooth plate 2 45 and the sliding frame 31. Tooth plate 2 45 is meshed with tooth plate 1 44. The upper end of tooth plate 2 45 is located between the moving seat 342 and the sliding frame 31, and the moving seat 342 can contact tooth plate 2 45.

[0053] When the belt telescopic machine is in the extended state, the belt is tensioned to pull the movable seat 342 to move, and the lower end of the movable seat 342 moves close to the tooth plate 2 45. The tooth plate 2 45 is restricted to be away from the tooth plate 1 44 so that the tooth plate 1 44 can rotate, and the rotating rod 42 can rotate. The rotating rod 42 and the bottom plate 43 remain vertical under the state of gravity.

[0054] After the belt telescopic machine is extended, the telescopic rod three 252 is shortened, thereby reducing the distance between the moving rod 251 and the fixed frame 21, increasing the distance between the conveying roller 25 and the fixed frame 21, and the conveying roller 25 is close to the conveying roller six 34, which appropriately reduces the tension of the belt, so that the tooth plate two 45 contacts the tooth plate one 44, thereby re-limiting the rotation of the rotating rod 42, ensuring that the rotating rod 42 and the bottom plate 43 provide stable support for the front end of the sliding frame 31.

[0055] In further embodiments, see Fig.10 A limiting ring is provided on the fixed rod 41 at the side where the rotating rods 42 are close to each other.

[0056] The position of the rotating rod 42 is limited by the limiting ring, so as to ensure that the second tooth plate 45 is separated from the first tooth plate 44 after the movement, and ensure that the rotating rod 42 can rotate under the action of gravity.

[0057] In further embodiments, see Figure 2 , 6 One end of the fixed frame 21 is rotatably connected to one end of the frame 11, a telescopic rod 12 is installed between the frame 11 and the other end of the fixed frame 21, and a plurality of rollers are installed below the frame 11.

[0058] By extending the telescopic rod 12, one end of the fixed frame 21 can be lifted and rotated, so that one end of the fixed frame 21 can be raised, so that the telescopic belt conveyor can move goods between the low place and the inside of the carriage. The roller makes it easy to move the telescopic conveyor, thereby improving the convenience of the belt conveyor.

[0059] In further embodiments, see Figure 4 One end of the sliding frame 31 is connected to a sliding seat 32 , a roller is provided below the sliding seat 32 , and the sliding seat 32 is located inside the fixed frame 21 .

[0060] The sliding seat 32 supports the sliding frame 31 , and the rollers reduce the friction and resistance between the sliding seat 32 and the interior of the fixing frame 21 .

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
