Problems solved by technology

The existing rolling device consists of a pair of rolling dies respectively installed on the rotating rollers. Since the two rolling dies are rigid rolling extrusion during operation, impact and vibration force will inevitably be generated during extrusion, thus affecting The pressing effect of the new and old strips may even cause the failure of the connection between the new and old strips, thereby reducing the effective operation rate of the equipment and wasting strips

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The guide rolling device provided by the present invention comprises two rollers 1,11 which rotate relatively, and rolling molds 2,10 respectively arranged on the two rollers 1,11, wherein: the roller shaft 4 of the roller 11 and the power motor 5 Connected, the roller shaft 4 is provided with a driving gear 3, and the roller shaft 7 of the roller 11 is provided with a driven gear 6 meshed with the driving gear 3, which can be driven by the driving motor 5 through the driving and driven gears 3,6. The two rollers 1, 11 rotate synchronously, and then drive the two rolling dies 2, 10 to rotate;

[0018] Wherein, on the die surface of the extrusion start end 12 and the extrusion end end 13 of the rolling die 10, the front and rear sides are axially provided with a buffer end with a convex portion 9 on both sides and a concave portion 8 in the middle;

Abstract

The invention provides a guiding rolling device. The guiding rolling device comprises two rollers which rotate relatively and rolling dies which are arranged on the two rollers correspondingly. The guiding rolling device is characterized in that a buffering end with a protruding portion on at least one side and a concave portion in the middle is disposed in an axial direction on a die surface of an extrusion starting end of at least one rolling die. Vibration and impact force which occur at the moment when the two rolling dies just start to make rigid contact can be tolerated by the protrudingportions of the extrusion starting ends, meanwhile a new strip and an old strip are accommodated through the middle concave portions, the influence, on the strips, of vibration or impact force causedwhen the rigid contact occurs is eliminated fundamentally, and thus the new strip and the old strip can be smoothly rolled and connected to form one strip. Besides, vibration and impact force which occur at the moment when the two rolling dies are separated can be released through protruding portions of extrusion finishing ends, rotation speed fluctuation caused by the two rolling dies is reduced, thus the strip which is formed by rolling and connecting is delivered out stably, and the splicing quality of the new strip and the old strip is ensured.

Description

technical field [0001] The invention relates to a guiding and rolling device, in particular to a guiding and rolling device for splicing sheet strips, and belongs to the technical field including strip splicing. Background technique [0002] In the printing and packaging machinery and equipment, when the packaging tape is processed in the form of a coil, it is necessary to splice the head of the new tape with the tail of the old tape in a non-adhesive splicing method, so as to connect and provide the tape. Glue-free splicing is to press the new and old strips through the splicing and rolling device at a synchronous speed. The two pressing surfaces of the rolling device rotate in opposite directions at the same speed, and the new and old strips entering the two pressing surfaces Carry out rolling connection to complete glue-free splicing. The existing rolling device consists of a pair of rolling dies respectively installed on the rotating rollers. Since the two rolling dies ...
