[0037] The present invention will now be described in detail with reference to the drawings and embodiments.
[0038] Such as Figure 1-3 As shown, the core taking mechanism for roll paper core recovery of the present invention includes an automatic turning part 2, an automatic arrangement part 3, an automatic speed regulating part 4, a core taking part 5, and a negative pressure part 6 fixed on the frame 1. , Cut-off part 7, core removal reset part 8, core pressing part 9, in which the discharge end of the automatic turning part 2 is connected to the feeding end of the automatic arrangement part 3, and the automatic speed regulation part 4 is connected to the automatic arrangement part 3 At the discharging end, the core part 5 is fixed on the negative pressure part 6 above the discharging end of the automatic speed regulation part 4, the cut-off part 7 is arranged on one side of the core part 5, the core removal reset part 8, the core The pressing parts 9 are respectively located on both sides of the negative pressure part 6 and the core removal reset part 8 and the core removal pressing part 9 are separated by a plurality of stations.
[0039] Such as Figure 4 Among them, the automatic turning part 2 includes an inclined belt section 201, an inclined side baffle 202 on both sides of the inclined belt section 201, and a bottom baffle 203 at the bottom of the inclined belt section 201. The inclined side baffles 202 and bottom baffles 203 on both sides block Tilt the web on the belt section 201 to prevent it from falling. When working, the inclined angle of the inclined belt section 201 is set to 15°. When the roll paper is poured on the inclined belt section 201, because the axis of the roll paper is parallel to the inclined belt section 201, the angle of the roll paper and the inclined belt section 201 The friction is too small to overcome its own gravity, so it will not climb, but only roll on the inclined belt section 201. When the roll paper stands on the inclined belt section 201, because the axis of the roll paper is perpendicular to the belt 201, the contact area between the paper and the inclined belt section 201 increases and the friction between each other can overcome the roll paper itself. Gravity, so that the web can climb with the belt. Those rolls that are not perpendicular to the inclined belt section 201 will be rolled up under the impact of the rest of the roll paper or other external forces until the axis of the roll paper is perpendicular to the inclined belt section 201 to climb, thus reaching the roll paper Automatic rollover function.
[0040] Such as Figure 5 The automatic arrangement part includes a swing rod 303, an arrangement motor 304, a baffle 305, a central shaft 306, a first horizontal belt section 301, and a horizontal side baffle 302.

During operation, the arrangement motor 304 drives the swing rod 303 to swing at a constant speed at a speed of about 30 revolutions per minute, thereby driving the baffle 305 to rotate around the central axis 306. Under the action of the baffle 305, with the rotation of the first horizontal belt section 301, the roll paper is leaned to one side, thus realizing the automatic arrangement of the roll paper.
[0041] Such as Image 6 Among them, the automatic speed regulation part includes a second horizontal belt section 401, a third horizontal belt section 402, two photoelectric switches 403 installed at the head and end of the third horizontal belt section 402, an arc retaining ring 404, a spring 405, and a Speed motor 406, in which the arc retaining ring 404 is fixed at the end of the third horizontal belt section 402, a spring 405 is connected between the arc retaining ring 404 and the frame 1 on the side of the third horizontal belt section 402, and the speed regulating motor 406 Fixed on the rack. The cam divider 605 sets the working speed. Two photoelectric switches 403 are installed at the head and end of the third horizontal belt section 402 to detect whether there is a roll of paper passing through each position. The time difference detected by the two photoelectric switches It also reacts to the PLC (model S7226). The PLC adjusts the speed adjustment motor 406 to adjust the speed. When the photoelectric switch 403 at the end cannot detect the web, the PLC controls the speed adjustment motor 406 to slow down the second horizontal belt section 401 When the photoelectric switch 403 at the head end cannot detect the roll paper, the PLC controls the speed regulating motor 406 to stop. The speed of the third horizontal belt section 402 is twice as fast as the speed of the second horizontal belt section 401, and the speed is increased to avoid jamming of the roll paper. When the roll paper reaches the arc retaining ring 404, because the spring 405 pulls the arc retaining ring 404 and blocks the roll paper, the roll paper stays on the arc retaining ring 404. And when Figure 7 The suction head 508 in the middle is inserted into the roll paper core. As the cam divider 605 drives the rotation of the big turntable 602, the roll paper breaks through the tension of the spring 404, and the suction head 508 drives the roll paper away. At the same time, as the spring 405 returns, The arc retaining ring 404 also returns to the original position, blocking the next roll of paper.
