Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] From Fig. 1 and Fig. 2, the material receiving in the prior art adopts the overlapping method, the rotary boom 2 is fixed on the rotary support 1, and the cutting knife mechanism 3 and the swing roller 5 are fixed on the frame 4. When receiving materials, the swivel arm 2 rotates clockwise so that the new material roll 14 is transferred to the receiving position, and the cutter mechanism 3 also arrives at the receiving position. When the linear velocity of new material roll 14 loading is identical with old material roll 15 linear speeds, cutting knife mechanism 3 earlier sticks together new and old material with adhesive tape, and then old material is cut off, and lap is completed.

[0016] In Fig. 3 and Fig. 4, the slewing arm 2 is fixed on the slewing support 1, the cutter mechanism 3,...

Abstract

This invention provides a high speed synchronous paper but-joint device of an unit gravure machine including a turning frame, a turning big arm, a cutting unit, a frame, a swing-roller, a paper-end cutter fixed on the frame, a large roller and a paper roller with back-adhered glue, in which, the paper-end cutter is under the large roller driven by an executing cylinder, a test photoelectric eye is set on the cutter, a steel strip is set on the head of a paper roll, a coder is set on the big roller and the back-adhered paper roll is driven by the executing cylinder and the steel strip is adhered on the head of a new material with a double-side adhesive tape.

Description

technical field [0001] The invention relates to an unwinding and receiving device of a unit-type gravure printing machine, more specifically, a high-speed synchronous docking device for paper of a unit-type gravure printing machine. Background technique [0002] The traditional unwinding and receiving device of the printing machine adopts the lap splicing method, which makes the new and old feed heads superimposed in double layers, and is connected with a single-sided adhesive tape. Although this method can achieve the purpose of material splicing, there are problems: on the one hand, the single-sided adhesive tape is not strong enough to connect and is not suitable for high-tension occasions; Auxiliary machine, resulting in damage to the auxiliary machine. Contents of the invention [0003] Aiming at the deficiencies in the existing technology, in order to realize the connection of double-sided adhesive tape, av...
