Description

a conveyor roller

technical field

The invention relates to a workpiece conveying device, in particular to a conveying roller table.

Background technique

We know that in the production and manufacture of mechanical parts such as crankshafts, many processing procedures are required. It generally uses roller conveying equipment for turnover conveying between processes. Commonly used roller conveying equipment is divided into two types: unpowered conveying roller table and powered conveying roller table. Items need to apply external force to move on the unpowered roller table, and the item can stand still at any time or move back and forth freely under the action of external force. On the powered roller table, the items are driven by the rollers and will automatically move in one direction. Therefore, the above-mentioned two kinds of roller tables cannot satisfy the requirement that the article can be driven by the rollers to move automatically, and can move freely back and forth on the roller table.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a new type of conveying roller table with reasonable structure, convenient assembly and simple manufacture, which not only has the function of a power track, but also can be used as a non-powered roller table.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a conveying roller table, which is provided with a fixed bracket, and a number of rows of unpowered rollers are installed on the fixed bracket, and the feature is that: the internal measurement of the fixed bracket passes through two pairs of lifting cylinders A movable bracket that can be lifted up and down is installed. A motor and several rows of power rollers are installed on the movable bracket. A sprocket is installed on the power roller. The motor drives the power roller to rotate through a chain. There is a long hole in the middle of the adjacent power rollers on the movable bracket. , the rotating shaft of the non-powered roller passes through the long hole of the movable support, and is fixed on the fixed support by bolts, and the non-powered roller can rotate freely around its own rotating shaft.

Said lifting cylinder of the present invention is fixed on the fixed support through the cylinder bracket, and the cylinder rod of the lifting cylinder is connected and fixed with the movable support through the connecting block.

The present invention adopts the above mechanism, and the lifting cylinder can drive the movable support installed with the power roller and the drive motor to move up and down, so that the power roller is slightly higher or lower than the non-power roller. Compared with the prior art, the present invention has reasonable structure, convenient assembly, and simple manufacture. When the power roller is slightly higher than the unpowered roller, the power roller contacts the conveyed article and drives the conveyed article to move, and the roller table has the function of a power roller table ; When the powered roller is lower than the unpowered roller, the unpowered roller is in contact with the conveyed item, and the roller table has the function of the unpowered roller table again at this moment. The invention not only has the function of a power track, can be driven by the power roller to move automatically, but also can be used as a non-power roller table, which can freely move back and forth on the non-power roller table, and is suitable for the turnover transportation between processes in the processing of crankshafts and other mechanical components .

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a cross-sectional view along line A-A of Fig. 1 .

Fig. 3 is a sectional view along line BB of Fig. 2 .

Fig. 4 is a CC sectional view of Fig. 2 .

In the figure: 1. Fixed bracket, 2. Sprocket, 3. Bolt, 4. Power roller, 5. Unpowered roller, 6. Movable bracket, 7. Connection block, 8. Lifting cylinder, 9. Transmission chain, 10. Motor, 11. motor sprocket, 12. cylinder support.

Detailed ways

It can be seen from Fig. 1, Fig. 2, Fig. 3, and Fig. 4 that a conveying roller table is provided with a fixed bracket 1, and several rows of unpowered rollers 5 are installed on the fixed bracket 1, and the unpowered rollers 5 are formed by bolts. 3 is fixed on the fixed bracket 1, and the unpowered roller 5 can freely rotate around its own rotating shaft. Unpowered rollers are free-rotating rollers that do not have a driving effect on the conveyed goods.

The inside of the fixed support 1 is equipped with a movable support 6 that can be lifted up and down through two pairs of lifting cylinders 8 . Said lifting cylinder 8 is fixed on the fixed support 1 by the cylinder bracket 12, and the cylinder rod of the lifting cylinder 8 is connected and fixed with the movable support 6 through the connecting block 7. The movable bracket 6 is plate-shaped, and several rows of power rollers 4 and drive motors 10 are installed on it; the power roller 4 is equipped with a sprocket 2, and the motor 10 is equipped with a motor sprocket 11, and the motor sprocket 11 and the sprocket 2 pass through the transmission chain. 9 are connected together, and the motor 10 drives the power roller 4 to rotate. The power roller 4 is a roller that drives the conveyed article.

It can also be seen from Fig. 1, Fig. 2 and Fig. 4 that a long hole is provided in the middle of the adjacent power roller 4 on the movable support 6, and the rotating shaft of the non-powered roller 5 passes through the long hole of the movable support 6, and passes through the bolt 3 Fixed on the fixed bracket 1, the unpowered roller 5 can freely rotate around its own rotating shaft. Because the lifting cylinder 8 is installed on the fixed bracket 1 through the cylinder bracket 12, and the cylinder rod of the lifting cylinder 8 is connected with the movable bracket 6 through the connecting block 7, so when the lifting cylinder 8 moves, it drives the movable bracket 6 to move up and down, so that the installation The power roll 4 on the movable support 6 can move up and down between two adjacent unpowered rolls 5, making it higher or lower than the unpowered roll. And it will not hit the unpowered roller when moving up and down. When the powered roller 4 was slightly higher than the unpowered roller 5, the roller table had the function of the powered roller table; when the powered roller 4 was lower than the unpowered roller 5, the roller table had the function of the unpowered roller table again.
