Description
Technical field
The utility model is related to a kind of equipment for completing firework external cylinder bottom nozzle crimping and paper bar bar back cover.
Background technology
Combined firework is the firework product being composed of multiple monotubulars.One monotubular is exactly a fireworks paper tube, due to
The inner cylinder for loading effect medicine is often packed into monotubular, the also referred to as described monotubular is outer barrel or firework external cylinder in the industry.It is rolled by paper
Made of two ports of firework external cylinder be all open state.In traditional handicraft the bottom nozzle of firework external cylinder by the system of building of pressurizeing mud
Layer (being commonly called as mud head or mud bottom) is closed.In order to avoid the mud layer system of building is not easy, structural strength is limited, is unfavorable for the disadvantages such as recycling
End, now with a kind of novel firework outer barrel, to carrying out crimping processing at cylinder bottom nozzle：With corresponding mould (such as patent document CN
" firework launching paper web bottom molding die " disclosed in 205980955U) it is sleeved on cylinder bottom nozzle and carries out rotation to it and apply
Pressure so that the barrel of cylinder bottom end is whole to be bent to cylinder lumen, forms a cricoid flanging part；Then from the top of cylinder
Port punching press is packed into paper bar bar, and paper bar bar is covered in cylinder lumen and is glued on the flanging part, to closed circular crimping
The mesoporous in portion.The bottom nozzle of the combined closing firework external cylinder of flanging part and paper bar bar, referred to as crimping back cover, it is original to substitute
Mud bottom.
Above-mentioned paper bar bar is Circular cartons, is commonly called as paper bar bar, existing relevant paper bar bar stamping equipment such as patent text in the industry
It offers " a kind of back cover paper bar bar the prime machine of fireworks paper tube " disclosed in CN106871737A.In addition, in the closed tradition of mud layer
In the processing of combined firework also include cut, punching press paper bar bar be packed into firework external cylinder process and equipment：Cutting mechanism round mouth
Cutter cuts lower paper bar bar on cardboard or paper tape, and paper bar bar is pressed into firework external cylinder by punching mechanism jumper bar.Paper bar bar is divided into
Have mesoporous paper bar bar and without mesoporous paper bar bar, have mesoporous paper bar bar for in outer barrel drug and effect part be layered every
From no mesoporous paper bar bar is used to block the top ports of outer barrel, and paper bar bar described in the utility model belongs to no mesoporous paper bar bar.
In order to realize this crimping back cover firework external cylinder automated production, disclose following patent Shens in the prior art
Please, title：A kind of crimping bottom closing device of combined firework outer barrel；Application number：CN201710924871.6；The applying date：2017-
10-02；Publication number：CN107478102A；Publication date：2017-12-15.As the further developmental achievement of the project, this practicality
It is novel that the patent document is cited in full text.
Go deep into practice with research and development, the bottom end mouth-shaped of this novel firework outer barrel can also be processed into new envelope
Flat-bottom structure is closed, referring to Fig. 1,2 comparison：

Specific implementation mode
Referring to attached drawing, reflect that a kind of concrete structure of the utility model, the crimping bottom closing device of the fireworks paper tube include
The turntable 6 of intermittent rotary, rotary tray motor 13 sequentially drive turntable by speed changer 12, transmission shaft 11, interrupted division runner assembly 8
10 intermittent rotary of central shaft.
Circumferentially eight groups of detent mechanisms, every group of detent mechanism include that four cylinders arranged side by side position on the turntable 6
Core bar 601, the positioning core bar 601 rotated with turntable 6 during by the upper cylinder station 1 that is fixed in rack 14,
Paper bar bar stamping station 2, the second shaping station 4, moves back a station 7 at first shaping station 3：
The upper cylinder station 1 is equipped with lower hopper 101, and the feed opening of the lower hopper 101 is set there are four material-dividing groove 102, point
Hopper 102 is correspondingly arranged with cylinder positioning core bar 601, and upper cylinder device includes four upper cylinder push rods 15 of cylinder driving, upper cylinder push rod
The firework external cylinder 100 of 15 102 bottom ends of promotion material-dividing groove along cylinder, axially be inserted on the positioning core bar 601 by correspondence.
The paper bar bar stamping station 2 includes that the paper bar bar of the corresponding cylinder positioning setting of core bar 601 cuts press machine
Structure：It cuts a sheet of paper and paper stack 207 was set between broach shell 205 and anvil of cutting a sheet of paper set 206；The paper of crossing that paper bowl and its driving motor are constituted is crossed to drive
Paper tape is sent into the paper stack 207 excessively by dynamic component 208；Cylinder 203 of cutting a sheet of paper drives broach shell 205 of cutting a sheet of paper by transmission levers 209
Action, cuts paper bar bar on paper tape；Integrally 201 lead agency of driving cylinder is whole on cylinder positioning core bar 601 for paper bar bar
Firework external cylinder 100 move, the end of firework external cylinder 100 be nested in cuts a sheet of paper anvil set 206 in；The drive of paper feeding cylinder 202 is sleeved on
Paper bar bar is sent into firework external cylinder 100 by the paper feeding mandril 204 cut a sheet of paper in broach shell 205.
This example includes the first shaping station 3 and the second shaping station 4, and substep completes shaping work, to shorten turntable 6
Intermittent periods improve production efficiency.The mechanism setting of two shaping stations is identical.Illustrate its knot by taking the first shaping station 3 as an example
Structure.The shaping mechanism of first shaping station 3 includes the rotation pressure mold that the corresponding cylinder positioning core bar 601 is arranged
303；For the die cavity of rotation pressure mold 303 by being connected to glue organization of supply into glue component 302, shaping mechanism is whole whole in molding
Firework external cylinder 100 under the driving of body driving motor 304 on cylinder positioning core bar 601 moves, the end sleeve of firework external cylinder 100
Enter in the die cavity of rotation pressure mold 303, rotation pressure mold 303 rotates side in the driving of molding motor 301 and oppresses below

Inner cavity is bent；
Second step, using second step molding die as shown in figure 11, the cylindrical mold cavities of mold are sleeved on the cylinder after bending
Rotary squeezing on port part outer wall coordinates with positioning core bar 601, and bending part is pressed into plane body structure and closed cylinder end
Mouthful.Paper bar bar covers and is glued on the plane body.
Since closed flat bottom structure must have positioning core bar and the cooperation of rotation pressure mold that could be molded, so this practicality
Novel device can easily take into account the molding needs of two kinds of structures.
The station 7 that moves back moves back a device equipped with what the corresponding cylinder positioning core bar 601 was arranged, and it includes being installed on to move back a device
Move back and move back a scraper plate 701 on a substrate 702, draw close driving cylinder 703 promotion move back a scraper plate 701 along positioning core bar radial motion lean on
Hold together cylinder positioning core bar 601, moves back cylinder and the drive of cylinder (not shown) is driven to move back the whole edge positioning core bar axial movement of a device.Set
Firework external cylinder 100 on positioning core bar 601 exits positioning core bar 601 by moving back the promotion of a scraper plate 701.
It with the rotation of turntable 6, moves back to complete to move back the positioning core bar 601 of cylinder on a station 7 and returns to cylinder station 1, follow according to this
Ring works.
Above-mentioned realization method is merely to clearly illustrate the technical solution of the utility model, and should not be understood as to this
Utility model makes any restrictions.The utility model has well known a variety of replacements or deformation in the art, is not taking off
Under the premise of from the utility model in essence meaning, the scope of protection of the utility model is each fallen within.
