Detailed Description

As shown in fig. 1, the high precision paperboard conveying device is an important component of a paperboard cutting machine, and if the conveying speed of the conveying device cannot be kept consistent, the cutting line has errors.

As shown in fig. 2, this kind of high accuracy cardboard conveyor is including last compression roller 1 and carrying the power supply, and the below of going up compression roller 1 is equipped with pivot 2 (the secant device just installs in pivot 2, through rotating pivot 2, the cardboard just can be cut into to secant device's transverse cutter), in order to solve the not enough that prior art exists, the utility model discloses rotationally install in pivot 2 with last compression roller 1 cooperation lower pinch roller 3 of form advancing (lower pinch roller 3 passes through the bearing and installs on pivot 2), install drive roll 5 in one side of lower pinch roller 3, be equipped with friction pulley 4 (for the rubber tyer) between drive roll 5 and the lower pinch roller 3, this friction pulley 4 all contacts with drive roll 5 and lower pinch roller 3, and drive roll 5 passes through the hold-in range with last compression roller 1 and is connected with carrying the power supply transmission.

The working principle of the high-precision paperboard conveying device is as follows: carry the power supply to pass through the hold-in range and drive roll 5 and last compression roller 1 and rotate, because drive roll 5 and friction pulley 4 contact, drive roll 5 rotates just so and drives friction pulley 4 through frictional force and rotate, because friction pulley 4 also contacts with lower pinch roller 3, so friction pulley 4 drives pinch roller 3 through frictional force again and rotates, and last pinch roller 3 is just pressing the cardboard with last compression roller 1 and is carried down. Because the diameter of pinch roller 3 everywhere all is unanimous down, do not have the problem that the thickness is inconsistent like the conveyer belt, consequently conveying speed is more unanimous, and the transport accuracy is higher, and the cardboard secant is also more accurate.

In order to enable the friction wheel 4 to tightly act on the driving roller 5 and the lower pressure wheel 3, the utility model discloses install the friction wheel 4 on the friction wheel seat, and be equipped with the spring 6 that the drive friction wheel seat moved up in the below of friction wheel seat. By means of the spring 6, the friction wheel 4 can be forced against the drive roll 5 and the lower pinch wheel 3, which enables a better friction transmission.

In order to make the cardboard can carry more steadily, the utility model discloses back rubber roll 7 is still installed to the rear side at last compression roller 1, is equipped with the back compression roller 8 of form advancing with the cooperation of back rubber roll 7 in the below of back rubber roll 7, then the rubber roll 7 passes through the hold-in range with back compression roller 8 and is connected with the transmission of carrying the power supply (the hold-in range be same hold-in range, the synchronism is better like this), in addition back compression roller 8 is the same with the linear velocity of drive roll 5 (drive roll 5 is the same with the linear velocity of lower pinch roller 3, consequently back compression roller 8 is the same with the linear velocity of lower pinch roller 3). When the paper board is conveyed, the rear rubber roller 7 and the rear pressing roller 8 press the paper board for conveying, and the rear rubber roller 7 is made of rubber materials, so that a larger friction force can be given to the paper board, and the linear speeds of the rear pressing roller 8 and the lower pressing roller 3 are consistent, so that the paper board can be conveyed forwards more stably. It is worth mentioning here that the friction wheel 4 may be located between the drive roll 5 and the lower pressure wheel 3, or between the rear pressure roller 8 and the lower pressure wheel 3, and the rear pressure roller 8 may function as the drive roll.

In order to further promote the stationarity that the cardboard was carried, the utility model discloses be equipped with the preceding rubber roll 9 of form advancing with the cooperation of drive roll 5 in the top of drive roll 5, preceding rubber roll 9 passes through the hold-in range with drive roll 5 and is connected with carrying the power supply transmission with the drive roll. Through the structure, the rear pressing roller 8, the lower pressing wheel 3 and the driving roller 5 can drive the paper boards to be conveyed forwards at the consistent linear speed, so that the stability of paper board conveying is improved to the maximum extent, and the paper board cutting line is more accurate.

In order to adjust the position of pinch roller 3 down to adapt to not unidimensional cardboard and carry, the utility model discloses install pinch roller 3 on the sliding sleeve through the bearing down, but the sliding sleeve axial displacement ground is installed in pivot 2 (through the axial key). By this structure, the sliding sleeve can move on the rotating shaft 2 along the axial direction of the shaft key, and the rotating shaft 2 can drive the sliding sleeve to rotate.

Finally worth mentioning is, in order to carry out the secant to the cardboard, as shown in fig. 4, the utility model discloses install semicircle sword 10 in pivot 2, 2 pivoted secant power supply transmission connections of pivot drive shaft 2. The rotating shaft 2 rotates by the driving of the line cutting power source, so that the semicircular cutter 10 is driven to cut the line of the paperboard. It should be noted that the term "semicircular knife" does not refer to a semicircular knife, but refers to a knife that is not a full circle, as long as a notch that does not participate in cutting is properly reserved.
