Detailed Description

The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. The core plate feeding device comprises a feeding roller and a pressing roller 4, wherein the feeding roller comprises a plurality of unit rollers 5, the number of the unit rollers is at least two, the unit rollers 5 are independently provided with power, or the unit rollers share one power 10, the unit rollers or the unit rollers refer to at least two unit rollers, the pressing roller 4 is in press fit with the unit rollers 5, one unit roller can be provided with one pressing roller, or one unit roller can be provided with a plurality of pressing rollers, and the length of the unit roller is selected according to the length of the unit roller. In the second embodiment, the plurality of unit rollers 5 are arranged in the same row and share one power 10, and the couplers 16 are arranged between the adjacent unit rollers, namely, the unit rollers arranged in the same row are in transmission connection through the couplers, so that the unit rollers in the same row are driven to synchronously rotate by one power, and the power cost is saved; in the third embodiment, a unit roller 5 is provided with a power 10, the power is arranged below the unit roller, the unit roller is rotatably arranged on a unit seat 17, and one end of the unit roller is provided with a driving wheel and is in transmission connection with the output end of a motor through a synchronous belt 18. The power 10 can adopt a high-precision motor, such as a servo motor, each unit roller is synchronously driven, and the rotation speed of each unit roller is controlled by the servo motor so that each unit roller is synchronously driven.

The shorter the length of the unit roller 5 is, the less the unit roller is difficult to twist in the transmission process, the diameter can be correspondingly reduced, the processing cost of the feeding roller is greatly reduced, and the processing error is reduced, so that the unit roller cannot jump during high-speed feeding, the feeding is more stable, and the feeding length error is small; in fig. 4 and 5, a plurality of unit rollers are arranged in a straight line, and in fig. 3, the unit rollers are staggered from front to back, so that the unit rollers and the pinch rollers can be increased or decreased according to the width of the core plate, the practicability is higher, and the equipment cost is lower; moreover, the weight of the unit roller is reduced, the inertia of the unit roller is reduced, the fixed-length feeding is stable, the error is small, the thickness of the formed honeycomb core is uniform, the honeycomb core is bonded with the panel more firmly, and the surface of the honeycomb panel is smoother and better in quality.

Referring to fig. 1, the feeding roller conveys the material forward by a unit length, the front end of the core plate 6 is contacted with a baffle 9 of the transverse cutting mechanism, the unit length is the height of the formed honeycomb core, then the upper cutter 1 moves downwards and is meshed with the lower cutter 2 to cut off the core plate, the cut core strip enters the material cavity 19, the feeding roller conveys the material forward by a unit length again, and the process is repeated. The vibrating power during high-speed crosscut is big, and for avoiding the cutter relieving phenomenon, lower sword 2 is installed on blade holder 3, increases lower blade holder thickness, intensity, and during the crosscut, lower blade holder withstands the lower sword, increases the intensity of cutter, avoids the cutter relieving, and the feed roll will bypass blade holder 3 like this, consequently the distance grow of feed roll and cutter can influence the precision of pay-off like this. See and attach 2 and 3, in the embodiment one, unit roller 5 divide into preceding roller 7 and back roller 8, preceding roller 7 gos deep into blade holder 3, back roller 8 is outside the blade holder, that is to say, unit roller 5 is not on same straight line, can stagger the setting from beginning to end, also can divide into a plurality of groups, some unit rollers go deep into in the blade holder, be close to the cutter, because of the small size of unit roller, can not influence the intensity of blade holder like this, can be close to the cutter again, improve the precision of fixed length pay-off, and during high-speed crosscut, the cutter goes up and down and can drive the core, the core aversion can influence the cutting precision and the core length after cutting, be close to the cutter with the pinch roller of unit roller pressfitting like, push down the core, just so avoid the cutter to drive the core to go up and down and shift, thereby improve the precision of cutting. On the route of pulling, the unit roller distributes according to the horizontal broad width that the core was pull, though staggers the setting around the unit roller, but according to the broad width of core, it is even to distribute as far as possible for the horizontal position of core all has traction force, carries more stably like this, the utility model discloses according to the broad width of core, in order to choose for use the unit roller that corresponds, surpass the broad width part then the use of stopping, had so both guaranteed that the core is carried forward by stable, had played energy-conserving effect simultaneously.

The pinch roller 4 is rotatably arranged on a pinch roller seat 15, the pinch roller seat is arranged on a cross beam 11 and can transversely move on the cross beam, if the unit roller is short, one unit roller is provided with one pinch roller, and if the unit roller is longer, one unit roller can be provided with a plurality of pinch rollers; the transverse position of the pressing wheel on the cross beam 11 can be adjusted according to the length and the transverse position of the unit roller, so that the pressing wheel and the unit roller are pressed, the pressing wheel seat can be fixed on the cross beam through the locking bolt after the adjustment is finished, the cross beam can be made of square steel or provided with transverse limiting convex ribs in order to avoid the rotation of the pressing wheel 4 relative to the cross beam, and the cross beam 11 can be set into a screw rod structure and the like. The pinch roller seat 15 is including supporting seat 12 and swing arm 13, the swing arm is articulated with the supporting seat, pinch roller 4 installs the one end at swing arm 13, be equipped with on the supporting seat and make the pinch roller in the swing arm press to the spring 14 of unit roller, the elasticity of spring makes pinch roller 4 lean on to unit roller 5 all the time, and pinch roller and unit roller pressfitting are carried the core all the time.
