Spiral type transverse cutting machine
Technical field
The utility model relates to corrugated board production field of mechanical technique, particularly relates to a kind of spiral type transverse cutting machine.
Background technology
Spiral type transverse cutting machine is a kind of machinery being widely used in corrugated board production field, existing spiral type transverse cutting machine comprises cutter shaft and lower cutter shaft, upper cutter shaft and lower cutter shaft are separately installed with cutter, the spiral type transverse cutting machine of this structure, when shearing corrugated paper cutting plate, if the cutter be arranged on cutter shaft and lower cutter shaft " owes to be full of " assembling, then the corrugated board both sides shearing area machined is inconsistent, and burr is many; If cutter " interference " assembles, then easily produce the phenomenon of whetting a knife between cutter, thus reduce cutting-tool's used life.
Utility model content
For solving the problems of the technologies described above, the utility model provides that a kind of processing effect is good, the spiral type transverse cutting machine of long service life.
Spiral type transverse cutting machine of the present utility model, the transmission device comprising the upper cutter shaft that is oppositely arranged and lower cutter shaft and be connected with upper cutter shaft and lower cutter shaft respectively, be provided with between the output shaft of described transmission device and described upper cutter shaft and cog, be provided with lower gear between the output shaft of described transmission device and lower cutter shaft, described in cog and to engage with lower gear.
Further, spiral type transverse cutting machine of the present utility model, described transmission device comprises four groups, and wherein two groups are oppositely arranged on the both sides of cutter shaft, another two groups of both sides being oppositely arranged on lower cutter shaft.
Further, spiral type transverse cutting machine of the present utility model, described transmission device comprises motor and reductor, and the output shaft of described motor is fixedly connected with the power shaft of reductor, the output shaft of described reductor with to cog or lower gear is fixedly connected with.
Further, spiral type transverse cutting machine of the present utility model, described motor is servomotor.
Further, spiral type transverse cutting machine of the present utility model, described in cog and lower gear external toothing.
Compared with prior art the beneficial effects of the utility model are: the upper cutter shaft of spiral type transverse cutting machine of the present utility model is provided with and cogs, lower cutter shaft is provided with lower gear, and cog and lower gear intermesh, cutter on cutter on cutter shaft and lower cutter shaft can not be produced clash into and wear and tear, extend the service life of spiral type transverse cutting machine.On the other hand, cog and the setting of lower gear, instead of the design of roll-type up and down of original spiral type transverse cutting machine, and by the precise positioning of mechanically operated precise positioning and electrical control, instead of pure mechanical couplings makes the corrugated board both sides shearing area machined be consistent, and impulse-free robustness, improves the operating efficiency of spiral type transverse cutting machine and the product quality of corrugated board.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, spiral type transverse cutting machine of the present utility model, the transmission device 3 comprising the upper cutter shaft 1 that is oppositely arranged and lower cutter shaft 2 and be connected with upper cutter shaft and lower cutter shaft respectively, be provided with between the output shaft of transmission device and upper cutter shaft and cog 4, be provided with lower gear 5 between the output shaft of transmission device and lower cutter shaft, cog and to engage with lower gear.
The upper cutter shaft of spiral type transverse cutting machine of the present utility model is provided with and cogs, lower cutter shaft is provided with lower gear, and cog and lower gear intermesh, the cutter on the cutter on cutter shaft and lower cutter shaft can not be produced and clashes into and wear and tear, extend the service life of spiral type transverse cutting machine.On the other hand, cog and the setting of lower gear, instead of the design of roll-type up and down of original spiral type transverse cutting machine, and by the precise positioning of mechanically operated precise positioning and electrical control, instead of pure mechanical couplings makes the corrugated board both sides shearing area machined be consistent, and impulse-free robustness, improves the operating efficiency of spiral type transverse cutting machine and the product quality of corrugated board.
As preferably, spiral type transverse cutting machine of the present utility model, transmission device comprises four groups, and wherein two groups are oppositely arranged on the both sides of cutter shaft, another two groups of both sides being oppositely arranged on lower cutter shaft.Four groups of transmission devices are set, further improve the bearing distribution of spiral type transverse cutting machine, make it stressed evenly, the product quality of production is better.
As preferably, spiral type transverse cutting machine of the present utility model, transmission device comprises motor 6 and reductor 7, and the output shaft of motor is fixedly connected with the power shaft of reductor, the output shaft of reductor with to cog or lower gear is fixedly connected with.Reductor be arranged so that the speed of motor is mated with the speed of upper cutter shaft or lower cutter shaft.
As preferably, spiral type transverse cutting machine of the present utility model, motor is servomotor.Select servomotor, add precision and the controllability of spiral type transverse cutting machine.
As preferably, spiral type transverse cutting machine of the present utility model, cogs and lower gear external toothing.
Below be only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
