After the technical scheme is adopted, the invention has the following positive effects:

(1) according to the pressing device, two bearings are selected to clamp the cutter through bolt connection, firstly, the outer circumferential surface of the pressing device, namely the outer ring of the bearing, is in rolling contact with the upper end surface of the processed plate, and the pressing device presses the plate and simultaneously slots the plate, so that the plate is in a state with high flatness in the slot forming process, the accuracy of the slot formed is greatly improved, and the problem of inconsistent slot depths caused by uneven plate is solved. The rolling outer circumferential surface can prevent the upper end surface of the plate from being mechanically abraded due to the fact that the plate is tightly pressed in the grooving process, and the quality of the machined plate is improved.

(2) The groove arranged on the transmission roller can limit the machined plate, and the problem that the accuracy of the grooving straight line is reduced due to the fact that the machined plate is displaced left and right in the conveying process can be effectively avoided.

(3) According to the invention, the cutter is clamped in the accommodating groove, so that the phenomenon that the cutter slips in the machining process due to direct fixation of the cutter can be avoided. In addition, the inner rings of the opposite surfaces of the two bearings extend to form a boss, and the side wall of the boss is provided with an accommodating groove, so that the abrasion of the outer circumferential surface of the pressing device on the side wall of the cutter in the rolling process can be avoided. In addition, the clamping groove formed in the inner periphery of the bearing inner ring is clamped with the protrusion of the fixing unit, so that the pressing device can be prevented from rotating along the outer periphery of the fixing unit in the grooving process.

(4) In the long-stroke grooving production line, the unreeling machine, the grooving machine and the reeling machine are sequentially connected from left to right, the situation that the conventional grooving length is limited is changed, the plate on the unreeling machine can be subjected to infinite grooving, hundreds of meters of long grooves can be formed at one time, the situation that the conventional plate needs to be cut firstly and then grooved one by one is also changed, the situation that the operation procedures are various is also changed, an operator can directly level the plate with the opened long grooves firstly and then cut according to the required size, convenience, rapidness and high efficiency are realized, the problem that the grooving machine meeting the requirements needs to be customized independently when the extra-long groove is machined is solved, the production cost is saved, and the occupied area is reduced.

(5) According to the invention, the transition bridge and the deviation-correcting clamping and conveying device are arranged between the unreeling machine and the grooving machine, so that the plate is ensured to keep higher linear accuracy in the conveying process, the plate is prevented from displacing in the horizontal direction, and the transition bridge degree and the tensioning device are additionally arranged between the grooving machine and the reeling machine, so that the subsequent reeling can be ensured to be carried out smoothly.
