Further, the two-stage transmission mode is that the output gear of the reducer connects two adjacent first sprockets 201, the two adjacent first sprockets 201 are located in the middle of the entire conveying system, and the two phase The adjacent first sprockets 201 are respectively used as central transmission sources to drive the roller groups on both sides to rotate in turn.

Based on the above technical solutions, the two groups of rollers connected to the output gear of the reducer are set as the A roller group and the a roller group, respectively. Set as B roller set, C roller set and so on, and several roller sets on the side of a roller set away from A roller set are respectively set as b roller set, c roller set and so on; reducer The output gear drives the A roller set and the first sprocket on the a roller set to rotate, thereby driving the roller shafts of the A roller set and the a roller set to rotate, and the two rollers and the second chain connected to the roller shaft. The wheels rotate synchronously, and the second sprocket of the A roller group is connected with the second sprocket of the B roller group to drive the roller shaft of the B roller group to rotate. Install the roller on the B roller group and the first The sprockets rotate synchronously, and the first sprocket of the B roller set is connected with the first sprocket of the C roller set to drive the roller shaft of the C roller set to rotate. The rollers installed on the roller shaft of the C roller set and The second sprocket rotates synchronously; it is connected in sequence according to the above connection method, and the rotation of the A roller group drives the operation of the roller group on one side, and the same is true for the a roller group and the roller group on the other side. The two-stage transmission mode uses two sets of rollers as the power source, so that the driving force is transmitted to both sides respectively, ensuring the driving strength and driving efficiency, the transmission error is small, the transmission distance is short, and it is not easy to trip.

On the basis of the above, the present invention can also be driven by means of end transmission. The details are as follows: the output gear of the reducer is connected to a first sprocket 201, and the first sprocket 201 is located at the end of the entire conveying system. The first sprocket 201 is used as the end drive source to drive the roller group on one side to rotate.

Based on the above technical solution, this transmission mode is the same as the connection transmission mode of the above-mentioned A roller set, B roller set, and C roller set, and is suitable for short-distance transmission.

Further, two adjacent first sprockets 201 are connected by chain drive, and two adjacent second sprockets 202 are connected by chain drive, and the distance between two adjacent fixed module bases 5 is matched with the length of the chain. The gap between two adjacent fixed module bases 5 is positioned by the wedge-shaped block 203 , and several fixed module bases 5 on both sides of the support frame 1 are symmetrically arranged.

Based on the above technical solutions, during the assembly process of the traditional chain, the length of the chain should be adjusted according to the wheelbase of the sprocket, and the chain links should be appropriately increased or decreased. The minimum change unit is one chain link. In the transmission system with high precision requirements , there may be an error of half a link or less, causing the chain assembly to be too loose or tensioned, making the entire driveline run less smoothly. Especially in this device, one drive drives multiple independent roller groups to rotate through multiple chains. In order to prevent the accumulation of transmission errors from causing the entire system to stop, there is a high requirement for the transmission accuracy of each transmission unit. During the assembly process of the invention, the positions of each fixed module seat 5 should be properly adjusted in turn according to the length of the chain to ensure that the length of the chain is completely matched with the distance between the two adjacent fixed module seats, and the gap between the two adjacent fixed module seats is determined by After the assembly site is measured, a wedge-shaped block 203 matching the size of the gap is ground and assembled directly on the conveying system. The wedge block 203 can completely locate the position of the fixed module base 5 to ensure that the fixed module base 5 will not move when the connection between the fixed module base 5 and the support frame 1 is unstable, which affects the transmission accuracy. The assembling method of the present invention can ensure the post-order and infinitely adjustable spacing of the sprockets.

Further, the wedge-shaped block 203 is provided with a base, and the base is provided with bolt holes and is connected with the extension bolt holes 5.6 of the fixed module bases on both sides by bolts. The bolt hole 5.6 of the extension part on one side of the fixed module seat is open, which is convenient for adjusting the position of the connecting bolt of the wedge block 203 . It is ensured that the wedge block 203 is stably connected to the fixed module bases 5 on both sides.

Further, the first sprocket 201 and the second sprocket 202 of each roller set form a drive sprocket set, and a limit sleeve 204 and a spacer are arranged between the fixed module base 5 and the drive sprocket set to drive the A spacer, a disc spring 206 , a spacer and a locking ring 207 are sequentially arranged on the sprocket set toward the end face of the roller shaft 4 ; a spacer ring 205 is arranged between the first sprocket 201 and the second sprocket 202 .

Based on the above technical solution, the limit sleeve 204 ensures that the assembly positions of the drive sprocket group are consistent, and at the same time avoids interference between the drive sprocket group and the fixed module base 5 , the limit sleeve 204 , the isolation ring 205 , the disc spring 206 and the locking ring 207 cooperate to position the first sprocket 201 and the second sprocket 202 axially.

The working process of the present invention is as follows: the motor 2 drives the output gear of the reducer to rotate, drives the first sprocket 201 connected to the output gear of the reducer to rotate, and passes through the gap between the adjacent first sprocket 201 and the second sprocket 202. The transmission connection drives all the rollers 4 to rotate, and the two rollers 6 fixedly mounted on the rollers 4 rotate to complete the conveying of the upper product.

When a certain group of rollers fails during the operation of the entire conveyor line, repair and replace the failed rollers. First, connect the first sprocket 201 and the second sprocket 202 of the rollers to be replaced. Remove the chain, then remove the wedge block 203 between the two adjacent fixed module bases 5, and then remove the connecting bolts between the two fixed module bases 5 of the roller set to be replaced and the support frame 1, and remove the entire roller set. During the replacement process, the lower positioning plane 5.1 at both ends of the new roller set should be positioned with the upper surface of the support frame 1, and the gap between the two adjacent fixed module bases 5 should be matched with the length of the chain. After the seat 5 is fixed, the wedge block 203 is used for positioning, and finally the chains connected to the first sprocket 201 and the second sprocket 202 are reinstalled. At this time, the maintenance of the conveying system is completed and the conveying system returns to normal operation.

The present invention has the following advantages:

1. The modular assembly method is adopted, which makes stocking possible and greatly shortens the production cycle;

2. The roller module is installed in the rear position. During installation, the chain can be continuously tensioned through the wedge block, without the need to set the side frame, and the spacing of the sprockets can be adjusted later.
