Abstract

The utility model relates to a hob cylinder rolling machine for making fire-cracker and fire-works, which is characterized in that the blade is embedded on the cylinder, so when the rolling machine is working, one side with cylinder rolls and presses the paper cylinder and one side with blade cuts the paper cylinder. Because the cutting distance is long, the cutting is started layer by layer from the inside layer; the blade is avoided from cutting the iron core, which prolongs the service life of the blade; the paper cylinders cut are well-bedded, which is convenient to stratify during the next process of final encapsulation. Meanwhile, the utility model is also provided with an iron core system, which can be automatically extracted and improve the production efficiency.

Description

Hob cylinder rolling machine for making fire-cracker and fire-works

The utility model is the rotary machine of a kind of firecracker, fireworks paper tube.

At present in the production of firecracker, fireworks, the rotary machine that adopts is that the inventor is No. 87206081 utility models (attached No. 87206081 application accompanying drawings) on April one, 1 to the application number of Patent Office of the People's Republic of China's application, though this machine can automatic reel, pressure cylinder in application and is cut tube, but the cutting knife of this machine and blade are loaded on end beam ends, blade cuts by the paper web surface up to iron core, blade is worn and torn by iron core sometimes, simultaneously, this machine still must manually be extracted iron core out after cutting tube, speed of production is restricted.

The utility model has designed a kind of rotary machine with the knife roller formula, cutter is embedded on the cylinder, and blade is successively cut by nexine when the cut paper tube, the limit crimping cuts, thereby prolong the cutting distance, disperse the stressed of blade, and cut by nexine, calibrate blade easily, blade is not cut and iron core, improved cutter life greatly, simultaneously, increase the device of automatic extraction iron core, thereby further improved work efficiency.

Main body of the present utility model is made of cylinder (1), end ship (7), blade (3), knife rest (2), automatic core-pulling device and actuating unit, have breach on the cylinder, chimeric and immovable support (2) and blade (3) on breach, knife rest (2) shape and cylinder breach coincide, form the cylinder of a band cutter, blade (3) is a circular arc, its arc radius and radius roller are about equally, blade (3) vertically parallel with the cylinder direction of rotation, when cylinder rotates, blade (3) lengthwise movement realizes cut state.The utility model establishes one from extracting iron core apparatus out at an end of end ship (7) outlet, this device is made of the transmission device (10) of a pusher dog (9) and this pusher dog of drive, the iron core that the utility model is used, one head that cooperates with pusher dog is arranged, there are magnetic device (8) and breast board (11) in ship exit, the end, when being sent end ship (7) with the paper web that has been cut of convenient ribbon core, held by magnetic device (8), pusher dog (9) draws (or hook) to live iron core head (12), and by transmission device (10) drive pusher dog (9), breast board (11) stops paper roll, and iron core is extracted.

Blade of the present utility model (3) can be sandwiched in the crack of knife rest (2), the two ends of blade (3) are connected and fixed on knife rest (2) with soft, on the knife rest (2), be positioned at blade two screw rods (4) are arranged behind, withstand blade (3), regulate this two screw rods (4), can regulate blade (3) angle of knife rest (2) relatively, can also play the effect of strengthening blade (3) simultaneously.

Cylinder of the present utility model can be by the size design of institute's chart drum, making volume press length is 1/3rd of roll circumference, at this assembly knife rest (2) and blade (3) on 1/3rd, and on the tube face of cylinder (1) and knife rest (2) opposite face, have window (6), so that regulate the screw rod (4) on the knife rest (2), to regulate blade (3).

The utility model is simple in structure, stable performance, easy to operate, reduce the wearing and tearing and the adjustment of blade, save artificial technology of extracting iron core out, enhance productivity greatly, simultaneously, be from the nexine to the skin, successively to cut owing to cut volume, institute's cut paper tube is well arranged, with the situation of paper web otch compacting, help the operation that layering is sealed in next procedure when avoiding former technology to cut from outside to inside tin.

An embodiment of the present utility model and description of drawings:

With the rotary machine of producing " in red big gun " is example, Fig. 1 is a rotary machine operation principle schematic diagram (laterally analysing and observe), Fig. 2 is a rotary machine structural representation (overlooking), the critical piece of embodiment comprises: the cylinder (1) and the identical knife rest (2) of cylinder breach that have a rectangle breach, account for 1/3rd of cylinder girth, insert in the blade (3) on knife rest (2) crack, blade adjustment screw rod (4), blade two ends and knife rest (2) be chain link (5) fixedly, be positioned at the blade adjustment window (6) on knife rest opposite on the cylinder, end ship (7), magnet (8), pusher dog (9), drive the chain system (10) of pusher dog (9), breast board (11), an iron core (12) is arranged, motor (13), gear-box formations such as (14).

Send paper and iron core to cylinder (2) and end ship (7) crack by preposition equipment during work,, the paper volume is pressed into tube by the rotation of cylinder (2), and in volume, pressure process, blade (3) is successively cut tube from nexine, ship (7) exit on earth, cut a pressure cylinder and finish, the paper web of ribbon core is held by magnet (8), and pusher dog is held the iron core head, breast board stops paper web, chain drives pusher dog, and iron core is extracted, and finishes reel, cuts tube, pressure cylinder, depoling operation.

Claims

1, band knife roller formula firecracker, fireworks reeling machine, by cylinder (1), end ship (7), blade (3), knife rest (2), automatic core-pulling device and actuating unit constitute, of the present utility model be characterised in that on the cylinder jagged, blade (3) and knife rest (2) are chimeric and be fixed on the breach, the shape of knife rest (2) and breach coincide, form the cylinder of a band cutter, blade (3) is a circular arc, its arc radius is close with radius roller, blade (3) vertically parallel with the cylinder direction of rotation, one end of end ship (7) outlet has a pusher dog (9) that is driven by power drive system (10), there are magnetic device (8) and breast board (11) in ship exit, the end, and iron core (12) has a head that cooperates with pusher dog (9).
