Description

Technical Field

[0001] The utility model belongs to the technical field of roller conveyors, and in particular relates to a double-chain transmission telescopic roller conveyor. Background Art

[0002] Roller conveyors are suitable for conveying items with a flat bottom. They are mainly composed of drive rollers, racks, brackets, drive parts, etc. They have the characteristics of large conveying capacity, fast speed, light operation, and can realize the diversion of multiple varieties on the same line. Roller conveyors are easy to connect and filter, and multiple roller lines and other conveying equipment or special machines can be used to form a complex logistics conveying system.

[0003] The utility model patent with domestic application number 202410381937.1 discloses a telescopic roller conveyor for pig feed, including a telescopic roller conveyor, a roller rod is threadedly connected to the surface of the telescopic roller conveyor, a support rod is threadedly connected to the surface of the telescopic roller conveyor, and also includes: a fixing component, the fixing component includes a round groove rod, and the top of the round groove rod is fixedly connected to the bottom of the support rod. In the present invention, when pig feed is placed at the conveying position of the telescopic roller conveyor, the gravity of the pig feed will be converted into pressure and transmitted to the bottom of the fixing component through the telescopic roller conveyor, thereby squeezing the fixing component to produce deformation to fix the telescopic roller conveyor, and a supporting component is arranged on the surface of the fixing component, and the supporting component uses the pressure of the pig feed to squeeze the ground, so as to use the pressure of the supporting component to fix the telescopic roller conveyor, thereby improving the stability of the telescopic roller conveyor when in use.

[0004] Telescopic roller conveyors are widely used in industries such as logistics and express delivery, clothing, and luggage. However, traditional powered telescopic roller conveyors are mainly based on poly-V belts, O-belts, and synchronous belts. Poly-V belts and O-belts have the disadvantage of being easy to slip, while poly-V belts have the disadvantage of being easy to loosen and jump teeth when turning. The above patent is used for pig feed transportation. Pig feed itself is heavy, and the use of poly-V belts and O-belts has the disadvantage of being easy to slip. Synchronous belts are not conducive to the roller conveyor turning. The roller conveyor of the utility model is used for conveying items such as logistics and express delivery, clothing, and luggage, and the weight is greatly reduced. In the process of transmitting materials, there is also wear and extrusion between the roller itself and the transmission structure. The above patent does not deal with the wear on the end of the roller, which reduces the stability of the roller conveyor itself during the transmission process, and easily causes the wear on the end of the roller and the slippage of the transmission structure, thereby affecting the normal use of the roller conveyor. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a double-chain transmission telescopic roller conveyor, characterized in that it comprises multiple groups of conveyor frames, telescopic frames installed between the conveyor frames, multiple groups of transmission rollers rotatably installed on the top of the telescopic frames, and a driving motor fixedly installed on the telescopic frames for driving the transmission rollers to rotate, a bearing seat is cooperatively installed inside the transmission roller, a mounting block is welded and installed inside the other end of the transmission roller, a mounting opening is opened on the mounting block, and one end of the bearing seat passes through the mounting opening and is fixedly installed with a shock-absorbing rod fixedly connected to the telescopic frame.

The frame plates are installed in two groups for cross-rotation, and both ends of the frame plates are respectively connected and installed with the transmission roller and the auxiliary rods through rotating components. One end of the fixed rod is installed with a sprocket group A through an auxiliary bearing.

[0007] The rotating components installed on the frame plates are used to rotate the frame plates at a certain angle to achieve the telescopic effect of the telescopic frame, and the fixed rod and the auxiliary rod are fixedly installed with the rotating components, which does not affect the rotation transmission of the A sprocket group on the fixed rod.

[0009] The setting of the rotating bearing makes it easier for the transmission roller to rotate between the frames without affecting the normal expansion and contraction of the frames. The bearing seat at the other end of the transmission roller cooperates to rotate, so that a shock-absorbing rod is added between the transmission roller and the frame for buffering, and the force between the transmission roller and the frame during the transmission process is weakened, thereby reducing the wear between the transmission roller and the frame, thereby ensuring the stability of the conveyor. The setting of the curved surface can reduce the situation where materials fall from both sides during roller transportation.

[0011] The rotating member is slid by the auxiliary slide groove, which protects both sides of the telescopic frame. At the same time, the top of the chain guard also protects the B sprocket group to a certain extent.

[0012] As a further preferred technical solution of the present utility model; a mounting seat is installed at one end of the driving motor, and the mounting seat passes through a group of the fixing rods and the auxiliary rods for fixed installation, and the output end of the driving motor is transmission-connected to the A sprocket group through the output sprocket group.

[0013] It is started by the driving motor, and the output end of the driving motor cooperates with the output sprocket group to drive the A sprocket group to rotate, so that the A sprocket group drives the transmission roller through the transmission chain to achieve the conveying effect of the conveyor without affecting the telescopic effect of the telescopic frame.

[0014] As a further preferred technical solution of the utility model, two groups of limit bars are symmetrically fixedly installed inside the conveyor frame, and the limit bars are provided with sliding grooves that cooperate with the sliding of the rotating member.

[0015] The two ends of the telescopic frame are limited by two sets of limit strips symmetrically fixedly installed on the inside of the conveyor frame, so as to ensure the overall stability of the conveyor during the conveying process, and at the same time, the angle adjustment of the conveyor frame between the telescopic frames is not affected, so as to ensure that the conveyor can be used for turning.

[0018] Beneficial Effects

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The setting of the rotating bearing makes it easier for the transmission roller to rotate between the frames without affecting the normal expansion and contraction of the frames. The bearing seat at the other end of the transmission roller rotates in coordination, so that a shock-absorbing rod is added between the transmission roller and the frame for buffering, and the force between the transmission roller and the frame during the transmission process is weakened, thereby reducing the wear between the transmission roller and the frame, avoiding the wear of the roller end and the slippage of the transmission structure, thereby ensuring the stability of the conveyor. The shock-absorbing rod can also reduce the transmission noise between the gear chains, and has a certain noise reduction function.

DETAILED DESCRIPTION

[0031] Telescopic roller conveyors are widely used in industries such as logistics and express delivery, clothing and luggage. However, traditional powered telescopic roller conveyors are mainly based on poly-V belts, O-belts and synchronous belts. Poly-V belts and O-belts have the disadvantage of being easy to slip, while poly-V belts have the disadvantage of being easy to loosen and jump teeth when turning. The cited patent is used for pig feed transportation. Pig feed itself is heavy. The use of poly-V belts and O-belts has the disadvantage of being easy to slip, and synchronous belts are not conducive to the roller conveyor turning. The roller conveyor of the utility model is used to transport items such as logistics and express delivery, clothing and luggage, and the weight is greatly reduced. In the process of transmitting materials, there is also wear and extrusion between the roller itself and the transmission structure. The cited patent does not deal with the wear on the roller end, which reduces the stability of the roller conveyor itself during the transmission process, and easily causes the wear on the roller end and the transmission structure to slip, thereby affecting the normal use of the roller conveyor.
