Abstract

A cutter shaft structure of a transverse cutting machine is characterized in that the ends of core shafts (70 and 71) are fixedly mounted on a box body (1) through expansion sleeves (8); self-aligning roller bearings are mounted on the core shafts (70 and 71); roller bearing supports (50 and 51) are fixedly mounted on the self-aligning roller bearings and fixedly assembled with rollers (60 and 61); roller rotation driving structures are mounted on the roller bearing supports (50 and 51) and at the ends of the rollers (60 and 61); cutter holders and cutters (100 and 101) are mounted on the outer sides of the rollers (60 and 61); the core shafts (70 and 71) are fixed; the roller rotation driving structures drive the rollers (60 and 61) to rotate around the core shafts. According to the structure, the core shafts are fixed while the rollers are rotated, which reduces inertia of rotation and the weight of cutter shafts so as to achieve an energy saving effect and reduce the bearing interval; the cutter shaft structure has good cutting stability and remarkable energy saving effect when used for cross cutting of wide paper boards (W is greater than or equal to 2,200).

Description

Technical field

The present invention relates to the package packing machine technical field of structures, when especially the wide cut cardboard laterally being cut, the design of cutter shaft drive mechanism.

Background technology

Transverse cutting unit is continuous corrugated board laterally to be cut into a kind of equipment that requires the length specification cardboard for corrugated paper board production line, it is by fifth wheel part, paper feed part, cutter shaft driving section, paper delivery partly forms, wherein the cutter shaft driving section is its core part, and the cutter shaft running accuracy requires high, and supporting rigidity is good, amount of deflection is little, it is few that cutter shaft is beated, if excesssive gap and can't cut paper, or the edge of a knife is interfered and is bumped cutter.For wide cut Paperboard cutting W 〉=2200 o'clock, such as Fig. 3,4, the cutter shaft structure of now widely used transverse cutting unit by servomotor drive input gear axle 1 ', the lower cutter tooth wheel 2 of input gear axle 1 ' drive ' and accent crack gear 3 ' and upper slitter gear 4 ', lower cutter tooth wheel 2 ' by key and lower cutter shaft 6 ' connect, transfer crack gear 3 ' and upper slitter gear 4 ' too with key and upper cutter shaft 5 ' connect, whole cutter shaft amount of spin was large when cardboard laterally cut, the cutter shaft global existence eccentric mass of High Rotation Speed, or the cutter shaft precision is not high beats large and cutting blade abrasion that cause is fast, the problem that life-span is short.Because the cutter shaft total quality is larger up and down, as adopting most on the market two drive-types, lower cutter shaft two ends respectively connect a motor, and cost will improve greatly, can not satisfy the needs of production of transverse cutting unit.

Summary of the invention

The object of the present invention is to provide a kind of precision height, the transverse cutting unit cutter shaft structure little, that transmission inertia is little of beating.

The object of the present invention is achieved like this, a kind of transverse cutting unit cutter shaft structure, comprise casing, on, lower cutter shaft component, the roller rotary drive structure, on, lower cutter shaft component comprises mandrel, roller, roller bearing seats, the roller rotary drive structure, tool rest, and cutter, the two ends of described mandrel are fixedly mounted on the casing by expansion set, self-aligning roller bearing is fixedly mounted on mandrel one end, the other end is cylinder roller bearing, roller bearing seats is fixedly mounted on the roller bearing, roller bearing seats and roller fixed installation, one end of described roller and described roller bearing seats is installed described roller rotary drive structure, there is the tool rest mounting plane in the described roller outside, at this mounting plane tool rest is installed, and cutter is installed on the tool rest; Described mandrel maintains static, and described roller rotary drive structure drives roller and rotates around mandrel.

Further, described roller rotary drive structure comprises driven tooth wheels and input gear axle, and described input gear axle is fixedly mounted on the casing by eccentric bushing, and driven wheel and the driven gear assembly of input gear axle in casing closed.

More preferably, described driven tooth wheels comprise pinion stand, gear and accent crack gear, and described pinion stand is fixedly mounted on by screw on the end face of described roller bearing seats, transfer crack gear, gear and the fixed installation of described pinion stand.

More preferably, described pinion stand is by the excircle orientation of self-aligning roller bearing.

More preferably, described accent crack gear and gear are by adjusting pin and pinion stand location.

Said structure adopts mandrel to fix, and the rotor cylinder rotates, and rotates the amount of whipping and cutter shaft weight thereby alleviated, thereby reach energy-saving effect, reduced simultaneously the supporting spacing of bearings at both ends, greatly improved the cutter shaft rigidity, for wide cut cardboard crosscut W 〉=2200 o'clock, cut good stability, energy-saving effect is remarkable.
