Description

The change of lap automatic rewinding machine of not shutting down that a kind of fracture is smooth

Technical field

The utility model relates to automatic rewinding machine technology field, the change of lap automatic rewinding machine of not shutting down that particularly a kind of fracture is smooth.

Background technology

The existing change of lap automatic rewinding machine of not shutting down mainly is made up of rewinding pressure roller 1, front side rewind roll 3, rear side rewind roll 7, core pipe push rod 4, core pipe guide groove 6, as shown in Figure 1.Front side rewind roll 3 is equal to core pipe 5 external diameters with the gap of rear side rewind roll 7 and the inner width of core pipe guide groove 6.After paper web 2 rewinding are good, to quicken by electrical control gear control rewinding pressure roller 1, its linear velocity is bigger than front side rewind roll 3, and paper web 2 is pushed out; Meanwhile, standby core pipe 5 core pipe push rod 4 are pushed up the rewinding position.Because its top layer linear velocity was bigger than the linear velocity that is wrapped in the paper 8 on the rear side rewind roll 7 when paper web 2 was released by rewinding pressure roller 1, so paper 8 is broken along perforated lines.Paper after breaking is wrapped on the standby core pipe 5, continues next rewinding circulation.In said structure, owing to be difficult to guarantee the quality of paper 8 punchings during actual the use,, so just cause the difficulty of sealing of paper web 2 so the fracture unfairness often occurs even paper is torn mashed.In order to guarantee sealing effect, existing automatic production lines is provided with the tail apparatus of repairing of a cover special use, and this is repaiied tail apparatus the paper that every paper web afterbody is about 200mm is cut away, and then paper web is sealed, will cause the waste in paper and man-hour like this, make said structure become complicated.

Summary of the invention

The change of lap automatic rewinding machine of not shutting down that provides a kind of fracture smooth is provided the purpose of this utility model, not only simple in structure, the disconnected paper of this machine seal and change of lap fast reliable, and can conserves paper, improve work efficiency.

The technical solution that the utility model proposed is such: the change of lap automatic rewinding machine of not shutting down that a kind of fracture is smooth, comprise rewinding pressure roller 1, front side rewind roll 3, rear side rewind roll 27, core pipe push rod 4, core pipe guide groove 6, dancing roll 30, front side rewind roll 3, rear side rewind roll 27, form a rewinding district between rewinding pressure roller 1 three rollers, the inner width of minor increment and core pipe guide groove 6 is equal to core pipe 5 external diameters between the roll surface of front side rewind roll 3 and rear side rewind roll 27, rotor 34 on rear side rewind roll 27 rear sides are respectively equipped with under the cut-out rotor 28 and cut off also, cutting off down, rotor 28 is equipped with cut-out cutter 32 down, its rear side has the pore 31 that communicates with negative pressure source, rotor 34 is equipped with cut-out upper slitter 33 in the cut-out, and cutter 32 points of a knife contacted under rotor 34 drove and drives by cam mechanism and cuts off upper slitter 33 points of a knife and cut off in the cut-out; Rear side rewind roll 27 with cut off down rotor 28 near tangent, and with cut off under have the pore 35 that communicates with negative pressure source on the pore 31 corresponding positions on the rotor 28; The dancing roll 30 that is positioned at rotor 28 rear sides under cutting off is approaching tangent with it.Described rear side rewind roll 27 but switched in opposite identical with the external diameter, the rotating speed that cut off rotor 28 down.Described front side rewind roll 3 is positioned on the same slide block with the front portion of core pipe guide groove 6.

Compared with prior art; the beneficial effects of the utility model to need only to be to increase some simple structures existing before not shutting down change of lap automatic rewinding machine rewinding district; and delete original tail apparatus of repairing; thereby it is fast reliable in the time of just can guaranteeing change of lap; owing to before the rewinding district, just can entirely cut off paper; this just is convenient to paper web and seals, and reduces paper waste, and easy to adjust, improved work efficiency.

The specific embodiment

Below by embodiment the utility model is described in further detail.

Referring to shown in Figure 2; the change of lap automatic rewinding machine of not shutting down that a kind of fracture is smooth is made up of rotor 34 and core pipe push rod 4, core pipe guide groove 6, core pipe 5 in rotor 28, dancing roll 30, the cut-out under rewinding pressure roller 1, front side rewind roll 3, rear side rewind roll 27, the cut-out.Front side rewind roll 3, rear side rewind roll 27, form a rewinding district between rewinding pressure roller 1 three rollers, the inner width of minor increment and core pipe guide groove 6 is equal to core pipe 5 external diameters between the roll surface of front side rewind roll 3 and rear side rewind roll 27, it is characterized in that: rotor 34 on described rear side rewind roll 27 rear sides are respectively equipped with under the cut-out rotor 28 and cut off, cutting off down, rotor 28 is equipped with cut-out cutter 32 down, its rear side has the pore 31 that communicates with negative pressure source, rotor 34 is equipped with cut-out upper slitter 33 in the cut-out, and cutter 32 points of a knife contacted under rotor 34 drove and drives by cam mechanism and cuts off upper slitter 33 points of a knife and cut off in the described cut-out; Rear side rewind roll 27 with cut off down rotor 28 near tangent, and with cut off under have the pore 35 that communicates with negative pressure source on the pore 31 corresponding positions on the rotor 28; The dancing roll 30 that is positioned at rotor 28 rear sides under cutting off is approaching tangent with it.

This machine working process is such: paper 8 behind dancing roll 30 place's change of directions under cut off rotor 28 enter into the points of tangency of rotor 28 and rear side rewind roll 27 under the cut-out, paper 8 has changed direction here and has entered into by the rewinding district that forms between front side rewind roll 3, rear side rewind roll 27, rewinding pressure roller 1 three rollers along rear side rewind roll 27 and carry out rewinding.The not contacted position of cutter 32 under rotor 34 is parked in and cuts off upper slitter 33 and cut off on cutting off in the rewinding process.When paper web 2 is about to rewinding when good, the cut-out upper slitter 33 cut-outs on the rotor 34 forwards preposition to by cam mechanism control, cuts off down that cutter 32 also turns to thereupon that this position contacts with cut-out upper slitter 33 and then with paper 8 cut-outs.After paper 8 was cut off, its previous section was continued to be incorporated into the rewinding of rewinding position to paper web 2 and finish the rewinding process.After 2 rewinding of about tube were good, rewinding pressure roller 1 was controlled its acceleration by electrical control gear, and its linear velocity is bigger than front side rewind roll 3, so paper web 2 is pushed out.Meanwhile, standby core pipe 5 core pipe push rod 4 are pushed up the rewinding district.Because cutting off down, the rear side of cutter 32 has the pore 31 that communicates with negative pressure source, the aft section of paper 8 then is attracted to be cut off on the following rotor 28, rotor 28 rotates along with cutting off down, the points of tangency of rotor 28 and rear side rewind roll 27 under paper 8 is introduced to and cuts off, at this moment, cutting off down, rotor 28 in-to-in negative pressure sources are cut off, rear side rewind roll 27 in-to-in negative pressure sources are then connected, because rear side rewind roll 27 and cut-out be the external diameter of rotor 28 down, identical and the switched in opposite of rotating speed, and pore 31,35 arrive this points of tangency again simultaneously, and paper 8 here is transferred on the rear side rewind roll 27.So paper 8 enters into the rewinding position along rear side rewind roll 27, this moment, rear side rewind roll 27 in-to-in negative pressure sources were cut off; Paper 8 is wound on the standby core pipe 5, begins next rewinding circulation.Can change the spacing between front side rewind roll 3 and the rear side rewind roll 27 and the inner width of core pipe guide groove 6 easily by moving slider group (Fig. 2 does not draw), use with the core pipe 5 that adapts to different size.
