Abstract

The utility model relates to a fuse feeder mechanism of a firecracker fuse-inserting machine. The fuse feeder mechanism comprises a driven fuse feeding roll and a drive fuse feeding roll, which are located on a fuse guiding device and installed in parallel in a mutual cooperation manner, wherein the drive fuse feeding roll undergoes separation and reunion with the driven fuse feeding roll through an elastic component and a cam mechanism, moves axially by means of a step mechanism and is driven to rotate by a power device arranged on the step mechanism. The fuse feeder mechanism disclosed by the utility model has the advantages that: a firecracker cake can pass through the fuse feeder mechanism in one step to complete a fuse inserting process, so that the defect that the firecracker cake needs to be changed in angles many times so as to pass through the fuse feeder mechanism in the prior art is solved, thus the working efficiency is greatly improved.

The utility model content

The purpose of the utility model provides a kind of sending of firecracker insertion-igniting machine of high efficiency and draws mechanism.

Realize that the technical scheme that the foregoing invention order adopts is following: mechanism is drawn in sending of firecracker insertion-igniting machine, comprise be positioned on the material guide device laterally arrange and cooperatively interact drivenly send pick-up roll and initiatively send pick-up roll; The said pick-up roll that initiatively send is realized and the driven clutch of sending pick-up roll through elastomeric element and cam mechanism, and by stepping mechanism realization axially-movable, is driven rotation by the power set that are located on the stepping mechanism.

Said stepping mechanism can be a pinion and rack driven by stepper motors, or turbine and worm driven by stepper motors mechanism.

After the utility model adopts said structure; Utilize elastomeric element to make initiatively to send pick-up roll and driven to send pick-up roll to realize adding of lead-in wire held and carry; Accomplish the slotting operation of drawing of firecracker; Initiatively send pick-up roll to advance vertically or retreat through stepping mechanism control, with increase or minimizing and drivenly send pick-up roll contacted distance, initiatively send pick-up roll and the driven quantity that pinches lead-in wire between the pick-up roll of sending thereby control; So just can satisfy the single pass of firecracker cake and originally send when drawing mechanism each row firecracker number different situation, the elastic force that cam mechanism is used to overcome elastomeric element cooperates stepping mechanism to make initiatively to send pick-up roll when axially-movable, can send pick-up roll realization clutch with driven.

The advantage of the utility model is: the firecracker cake can be disposable draw mechanism and accomplishes to insert and draw operation through sending, and having solved prior art needs the firecracker cake is changed angle repeatedly through sending the defective of drawing mechanism, thereby has improved operating efficiency greatly.

Further specify below in conjunction with the technical scheme of accompanying drawing the utility model.

The specific embodiment

See Fig. 1, Fig. 2; Mechanism is drawn in sending of firecracker insertion-igniting machine, comprises the material guide device that is located on the frame 13, and what on material guide device, laterally arrange and cooperatively interact drivenly send pick-up roll 4 and initiatively send pick-up roll 5; The driven pick-up roll 4 that send is fixedly installed on the frame 13; Initiatively send pick-up roll 5 to be located on the frame 13 through support 12, frame is provided with spring 11 and compresses initiatively sending pick-up roll 5 to press with the driven pick-up roll 4 that send, and frame is provided with cam mechanism 6; Cam mechanism 6 and spring 11 act on and initiatively send pick-up roll 5 realizations itself and the driven clutch of sending pick-up roll 4; Initiatively send an end of pick-up roll 5 to be connected with stepper motor 8, driven by stepper motor 8 and rotate, stepper motor 8 is realized with initiatively sending pick-up roll 5 to move vertically by another stepping mechanism control; Stepping mechanism is made up of another stepper motor driven gear 10 tooth bars 9 mechanisms, perhaps is made up of another stepper motor driven turbine and worm mechanism (drawing).

Operation principle: two of the firecracker insertion-igniting machine are sent in the pick-up roll, and the driven pick-up roll 4 that send is for fixedly installing, and another initiatively send pick-up roll 5 can move axially for activity setting.Initiatively send the length of pick-up roll 5 to be substantially equal to the length of the longest those delegation's firecrackers 3 in the middle of the regular hexagon firecracker cake 2.Insert when drawing; Firecracker cake 2 draws mechanism along guide plate 1 through sending; Initiatively send pick-up roll 5 at first be positioned at the driven rightmost that send pick-up roll 4 and with the driven pick-up roll 4 half position of staggering of sending; Make the part and the driven lead-in wire 7 that send pick-up roll 4 can just clamp the first row firecracker 3 of firecracker cake 2 on its left side, go between 7, stop operating when lead-in wire 7 is delivered to appropriate length when initiatively sending pick-up roll 5 rotations to drive whole row by initiatively sending pick-up roll 5 to send pick-up roll 4 clampings to carry the slotting row of first in the firecracker 3 firecracker 3 of guiding to driven; To go between by shearing device and 7 to cut off, promptly insert first capable.At this moment initiatively send pick-up roll 5 through cam mechanism 6 away from the driven pick-up roll 4 that send, discharge going between 7 clamping.Through stepping mechanism pushing stepping motor 8 and the diameter distance of initiatively sending pick-up roll 5 to move left a firecracker vertically; After completion is moved; Cam mechanism 6 is decontroled and is initiatively sent pick-up roll 5; Under the effect of spring 11, make and initiatively send pick-up roll 5 to be close to the driven pick-up roll 4 that send, carry out second the slotting of row firecracker 3 and send lead-in wire work, owing to initiatively send pick-up roll 5 and driven coincidence the external diameter distance of sending between the pick-up roll 4 apart from a firecracker 3 of increase; Corresponding with a firecracker 3 of the second row increase, at this moment draw and send a lead-in wire 7 to increase a firecracker 3 slotting needs (referring to Fig. 3) that draw to satisfy second row in the Far Left increase of initiatively sending pick-up roll 5; In like manner, preceding half cake of firecracker cake 2 is whenever inserted and is drawn delegation's firecracker 3 and will turn left to increase and send a lead-in wire 7, in the middle of being inserted into firecracker cake 2, inserts lead-in wire 7 radicals that draw (referring to Fig. 4) at most during those row firecrackers 3; The later half cake of past firecracker cake 2 continues to insert when drawing; Initiatively send pick-up roll 5 to continue to move to left along the axle stepping; At this moment different with slotting preceding half cake is initiatively to send pick-up roll 5 and driven coincidence distance increases a firecracker 3 of corresponding minimizing along with firecracker 3 line numbers the external diameter distance of sending between the pick-up roll 4; Whenever insert delegation's firecracker 3 and send a lead-in wire 7 with regard to reducing on the right; Up to last column firecracker 3 of having inserted firecracker cake 2, at this moment from initiatively sending pick-up roll 5 and moving to send the pin count of clamping between the pick-up roll 4 be the number (referring to Fig. 5) that is last column firecracker 3.Inserted after this cake, initiatively sent pick-up roll 5 to reset to the position that begins most toward the right fast automatically, that waits to get into next firecracker cake 2 slottingly draws circulation.
