Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a retractable belt conveyor. Background Technology

[0002] In the stamping industry, for transfer dies that require multiple stamping presses to operate in tandem, sheet metal or stamped semi-finished products need to be transferred between two stamping presses. Existing similar transfer dies use a two-dimensional structure for conveying sheet metal, which is relatively complex, bulky, and costly. It is suitable for use between larger stamping presses and dies, but it is not suitable for sheet metal transfer between smaller stamping presses. Furthermore, it cannot adjust the feeding distance of the feeding strip according to the distance between the blanking die and the stamping die, and cannot meet the needs of different die distances. Summary of the Invention

[0003] The purpose of this invention is to provide a compact, retractable belt conveyor suitable for transfer between small punch presses.

[0004] To overcome the shortcomings of the existing technology, the present invention adopts the following technical solution: a retractable belt conveyor device, comprising a conveying mechanism for conveying sheet material and an adjusting mechanism for extending or shortening the conveying mechanism.

[0005] The conveying mechanism includes a mounting frame, a telescopic frame slidably connected to the upper left of the mounting frame and with its upper end face flush with the upper end face of the mounting frame, a first pulley, a second pulley, a third pulley, a fourth pulley, and a conveyor motor for driving the fourth pulley to rotate, and a conveyor belt that wraps the first pulley, the third pulley, and the fourth pulley around its inner side. The second pulley moves with the telescopic frame and is always pressed against the outer side of the conveyor belt. Its position in the vertical direction is between the first pulley and the third pulley.

[0006] The adjustment mechanism includes a first drive wheel and a second drive wheel rotatably connected to the mounting frame, a drive belt wound around the first drive wheel and the second drive wheel, an adjustment motor for driving the first drive wheel to rotate, and a transmission block connected between the telescopic frame and the drive belt;

[0007] The regulating motor drives the drive belt to rotate, and the drive belt drives the transmission block and the telescopic frame to move in the same direction. At the same time, the second pulley moves with the telescopic frame. When the telescopic frame retracts into the mounting frame, the second pulley increases the compressed length of the conveyor belt. When the telescopic frame extends out of the mounting frame, the second pulley releases the compressed length of the conveyor belt.

[0008] In another embodiment, the mounting frame includes a top mounting bracket, a bottom mounting bracket parallel to the top mounting bracket and located below the top mounting bracket, a first fixed connecting plate and a second fixed connecting plate fixed between the top mounting bracket and the bottom mounting bracket and located on the sides of the top mounting bracket and the bottom mounting bracket, the rear end of the telescopic bracket passing through the front end of the top mounting bracket, the first fixed connecting plate being located at the front end of the top mounting bracket, and the second fixed connecting plate being located at the rear end of the top mounting bracket.

[0009] In another embodiment, the bottom of the top mounting bracket is provided with a through groove extending along the length of the telescopic frame. The upper end of the transmission block passes through the through groove and is fixedly connected to the telescopic frame. The middle part of the transmission block is sleeved on the drive belt and is fixedly connected to the drive belt located above while slidingly sleeved with the drive belt located below.

[0010] In another embodiment, the adjusting motor is mounted at the rear end of the mounting frame.

[0011] In another embodiment, the drive belt is disposed within the space enclosed by the conveyor belt.

[0012] In another embodiment, the conveying mechanism includes a fifth pulley rotatably connected to the rear end of the top mounting bracket, the fifth pulley being located above the fourth pulley and inside the conveyor belt.

[0013] In another embodiment, the conveying mechanism further includes a sixth pulley rotatably connected to the second fixed connecting plate, the sixth pulley being located above the fourth pulley and below the fifth pulley, and the sixth pulley always pressing against the outside of the conveyor belt.

[0014] In another embodiment, the fourth pulley is rotatably connected to the transmission block.

[0015] In another embodiment, the conveying mechanism includes a tensioning wheel mounted on the bottom mounting bracket and whose position is adjustable in the left-right direction.

[0016] In another embodiment, the adjustment mechanism includes a front bracket fixed to the front end and a rear bracket fixed to the rear end of the mounting frame, the first drive wheel being rotatably connected to the rear bracket, and the second drive wheel being rotatably connected to the front bracket.

[0017] Compared with the prior art, the advantages of this utility model are: the application has lower cost, smaller design structure, and more flexible installation. This solution solves the problem of material transfer and positioning of small punch presses and close-range material pieces, and solves the structural design that coordinates the adjustment of the feeding structure stroke with the movement of the feeding belt conveying the material pieces.

At the same time, the second pulley 132 moves with the telescopic frame 12. When the telescopic frame 12 is retracted into the mounting frame 11, the second pulley 132 increases the compressed length of the conveyor belt 15. When the telescopic frame 12 extends out of the mounting frame 11, the second pulley 132 releases the compressed length of the conveyor belt. When the telescopic frame 12 is adjusted to a suitable extension length, the conveyor motor 14 rotates to drive the conveyor belt 15 to rotate, thereby realizing the conveying of the material.
