Abstract

The invention provides a kind of firecracker that rolls automatically, firecrackers thick bamboo tube device, exactly with holding carton, vacuum cup, paper supplyor, active wheel, afterburning bow wheel waits parts to realize that mechanical action replaces the manual firecrackers that roll, firecracker, improved production efficiency, alleviated labour intensity, reduced cost, be the standardization of this product, the enforcement of seriation provides condition.

Description

The present invention relates to a kind of device that rolls firecrackers, firecracker automatically.

Fireworks, firecracker are the gifts that the people of various countries are used for observing the day, and the fireworks of China, firecracker are enjoyed quite high reputation in the international market.For a long time, the sector is produced most of lean on craft or semi-hand operation, and production efficiency is low, the cost height, and because manual operations, the product disunity has influenced the further raising of product quality.

Little big guns in firecracker, firecrackers and the fireworks etc. all are to utilize paper stock to roll into firecracker, form through a series of medicine preparation, filling again.Firecracker is first procedure and the semi-finished product that firecrackers are produced.The method that rolls firecracker at present has two: first one flat plate, amount to 1/3 with cutting out for the scraps of paper of specification, to put into a pin (iron wire of decision firecracker hole size or steel wire) thereafter, behind the some circles of usefulness hand rewinding, put the tail end of sizing at the scraps of paper, be placed on then on the platform, cover with a flat plank, two hands are carried on the back two ends on flat board, promote to form to a direction, after this, paper web and tube pin are pushed aside, promptly obtained a firecracker.Its two, the paper end is coated sizing and a tube pin is put in the gap of half a wooden garden arc frame (frame is provided with second arc wheel, the middle groove gap of setting up) simultaneously, promote thereafter to go up the arc yoke, be rolled into the back and transfer to a pin promptly to get a firecracker.All by manual operation, production efficiency is very low for above-mentioned method for coiling.

Purpose of the present invention, exactly with hold carton, vacuum cup, paper supplyor, active wheel, afterburning bow wheel, etc. parts realize that mechanical action replaces manual roll firecrackers, firecracker, improve production efficiency and product quality is for standardization, the seriation that realizes product creates conditions.

The present invention is described in further detail below with reference to accompanying drawing.

Figure one is a theory structure schematic diagram of the present invention.

Figure two is cutaway views of pointer setting device.

Shown in figure one, with the scraps of paper (3) that are cut into the specification material put into low early and high after, inclination certain angle open wide hold carton (1), the free heavily wheel (2) that rolls downwards pushes effect down during holding carton (1), the constantly downward handover of the scraps of paper (3).Actuating motor (16), drive reductor (15), by chain (14) driven gear (13), gear (13) and gear (11) thus engagement drives minor sprocket (9), chain (6) and sprocket wheel (5), make vacuum cup (4) spinning movement of separating paper (3), meanwhile actuating motor (21) drives vavuum pump (20), and the vacuum cup of rotation (4) revolution once holds a piece of paper sheet (3) and changes into playing the end-acted paper supplyor (7) of leveling paper feed.Hand remover seat (18) that rotates with active wheel (17) and the hand remover (12) that hand remover seat (18) in, moves with the scraps of paper (3) that are fed forward with build up with mechanism's rotation, the needle shaft (19) vertical with hand remover seat (18)

Shape, and along the direction of arrow of paper supplyor (7) enter lower edge be half garden arc rectangular block, in order to increase in the arc slot rolling that reinforcing bow wheel (10) that the scraps of paper roll frictional force and active wheel (17) form.At this moment, the sizing of storing in the sizing case (8) that also quantitatively discharges sizing splashes into from arc slot rolling top, garden through dropper, and when the needle shaft (19) with the scraps of paper (3) entered garden arc slot rolling, the scraps of paper one end of rolling promptly dripped sizing.Because the drive of active wheel (17), needle shaft (19) constantly rolls, and the scraps of paper are tightly twisted in the periphery of needle shaft (19), under the effect of reinforcing bow wheel (10), makes anti-mouthful of the firecracker (22) that is rolled into, does not unclamp.When hand remover seat (18) turns over certain angle, needle shaft (19) rolls the arc slot rolling from reinforcing bow wheel (10), and the work of rolling is finished.Because the rotation of cam (11), promoting hand remover (12) outwards moves from hand remover seat (18), shown in figure two, also owing to fasten needle shaft (19) in group syringe bar (23), finger axle (25) one ends are connected with group syringe bar (23), and the other end is under the cam (26) that rotates promotes, and finger axle (25) contracts needle shaft (19), group syringe bar (23) toward pusher, the firecracker of spooling (22) promptly falls from needle shaft (19) disengagement, realizes separating automatically.Along with the continuous rotation of hand remover seat (18), under extension spring (24) effect, dial syringe bar (23) and needle shaft (19) and stretch out forward, realize automatically reseting, begin next working cycles.

Need to change when rolling the firecracker specification, can select the relevant length size of hand remover and cam as requested or, satisfy the production needs of different wall firecracker by regulating arc slot rolling gap.

Firecracker automatic involution machine of the present invention not only can change manually rolling and be automated production in the past, reduces labor intensity, and can boost productivity simultaneously, reduce cost, and can be to the enforcement of the standardization of this product, seriation condition is provided.

Claims

1, a kind of automatic winder for firecracker, realize rolling automatically by the action of motor and mechanical part, it is characterized in that including deposit the scraps of paper (3) hold carton (1), the vacuum cup (4) of inhaling paper feeding sheet (3) and paper supplyor (7), store and quantitatively the discharging sizing sizing case (8) and the reinforcing bow that the scraps of paper (3) roll into firecracker (22) taken turns (10) and handsetting mechanism.

2, automatic winder for firecracker as claimed in claim 1, it is characterized in that holding carton (1) and be one low early and high after, be inclined to constant slope, the heavy wheel (2) of rolling pushing effect down, the scraps of paper (3) are the unlimited tank of handover down constantly.

3, automatic winder for firecracker as claimed in claim 1 is characterized in that afterburning bow wheel (10) is the rectangular block that a lower edge is half garden arc.
