Description

Abnormal shape section of thick bamboo row former of abnormal shape combination fireworks

Technical Field

The invention relates to a forming device of a special-shaped cylinder row of a special-shaped combined firework.

Background

The combined fireworks are usually composed of a single row of parallel arrangement of a plurality of paper firework cylinders, which are called cylinder rows. Then punching and inserting the firework cylinders in the cylinder row, namely, processing fire transmission holes on each firework cylinder by using punching needles, and then inserting leads into the fire transmission holes, so that the firework cylinders are connected in series through the leads to form a fire transmission relationship. The current processing cylinder rows are all vertical cylinder rows as shown in fig. 1, and the axes of all the firework cylinders of the vertical cylinder rows are in parallel and parallel relation. The upright tube banks are stacked and assembled to form a block (called a group basin), and the obtained product is called an upright combined firework. The inner cavity of the firework cylinder is provided with a medicine emitting and effect piece which is ignited by a lead wire.

The equipment to accomplish this is commonly referred to in the industry as a "potting machine" or "firework assembler". Is a relatively mature firecracker machine which is applied on a large scale. The working flow of the existing basin combining machine is as follows: discharging a plurality of firework cylinders to the upper row of the workbench surface to form a cylinder row at one time according to the required quantity by a discharging cylinder system; pushing out the cylinder rows on the working table surface in a row along the direction parallel to the central axis of the firework cylinder by a pushing device, and conveying the cylinder rows to a punching and inserting station under the clamping of the working table surface and the conveying roller set; the movable lead inserting system comprising a lead conveying mechanism completes a punching and lead inserting process; then gluing the side surfaces and the top surfaces of the firework cylinders in the cylinder row; under the pushing of the rear cylinder row, the front cylinder row on the workbench surface sequentially enters a forming system to stack and glue a plurality of cylinder rows to form a block-shaped whole. "a firework assembling machine" as disclosed in the chinese invention patent document with application publication number CN 102538597 a; the patent document of China patent application publication No. CN105486179A discloses a perforating and inserting device for a firework cylinder.

However, besides the vertical combined fireworks, special-shaped combined fireworks exist in the existing products, and the special-shaped combined fireworks are formed by combining special-shaped tube row laminates. In the invention, one end of the vertical or special-shaped cylinder row close to the punching insertion part is called as the lower end of the cylinder row or the firework cylinder, and one end far away from the punching insertion part is called as the upper end of the cylinder row or the firework cylinder. The arrangement structure of each firework tube of the special-shaped tube row is a fan-shaped tube row shown in fig. 2, a W-shaped tube row shown in fig. 3, a V-shaped tube row shown in fig. 4, a left-inclined tube row shown in fig. 5, a right-inclined tube row shown in fig. 6, a five-finger tube row shown in fig. 7, and the like; unlike the vertical tube row, the firework tubes of the special-shaped tube row have a certain inclined included angle (emission offset angle) with each other, the lower ends of the firework tubes are mutually close, and the upper ends of adjacent firework tubes have a tube-to-tube interval. So the current basin-assembling equipment can only finish the production of the vertical combined fireworks, but can not process the special-shaped fireworks.

In the prior art, the Chinese patent document with the application publication number of CN 110986690A discloses a firework cylinder production device with special-shaped arrangement and a production method thereof, an upright cylinder row for completing punching and inserting is processed into special-shaped arrangement by a firework cylinder special-shaped arrangement mechanism, the firework cylinder special-shaped arrangement mechanism comprises a fixed support and a firework cylinder groove, one end of the firework cylinder groove is connected with the fixed support and is arranged along the width direction of the fixed support, the connection position is a fulcrum of the firework cylinder groove capable of rotating left and right, wedge blocks capable of moving up and down are arranged at gaps between adjacent firework cylinder grooves, and the firework cylinder groove is pushed to rotate and swing for a certain angle through the wedge blocks and then positioned, so that the firework cylinder is in special-shaped arrangement.

The main disadvantage of the prior art is that when a plurality of wedge blocks are lifted and inserted into gaps of a plurality of adjacent firework cylinder grooves, the positions of the gaps are in an uncertain state which is continuously changed because all firework cylinder grooves swing, and the lifting of the plurality of wedge blocks and the swinging of the plurality of firework cylinder grooves are easy to generate movement interference, so that the working reliability of the firework cylinder is not high; meanwhile, the problem of lower production efficiency of the special-shaped cylinder row is solved, and the main reason is that the feeding and forming of the vertical cylinder row can only be completed at the same station, and the special-shaped row can be carried out only after the cylinder row is fed from the front end of the firework cylinder groove to the rear end along the axis direction of the firework cylinder during feeding, and the feeding stroke is longer, so that the forming period is longer, and the working efficiency is low.

Detailed Description

Example 1: referring to fig. 1-16, one specific configuration of the present invention is reflected. The special-shaped cylinder row forming equipment for the special-shaped combined fireworks is characterized in that the processing object is an upright cylinder row for punching and inserting in the existing firework basin assembling machine, and in the example, the upright cylinder row is processed into a fan-shaped cylinder row. In other embodiments, the processing object may be an upright tube row in which punching insertion is not completed.

The rack of the equipment is fixedly provided with a cylinder row bearing strip 101, and the cylinder row bearing strip 101 is arranged along the length direction of the equipment. Lifting type press strips 102 are correspondingly arranged above the cylinder row bearing strips 101, and the lifting type press strips 102 are driven to lift by press strip cylinders 103 at two ends of the frame.

The feeding station 104, the forming station 105 and the third station 106 are arranged in parallel along the barrel row carrier bar 101 in sequence: also included in the example are a fourth station 107, a fifth station 108, and a sixth station 109, also arranged side by side in this order.

The feeding station 104 comprises a lifting feeding moving platform 110, and the feeding moving platform 110 is provided with a feeding upper clamp 113 driven by a first clamp cylinder 111 and a feeding lower clamp 112 fixed on the feeding moving platform 110. After the vertical cylinder row A190 completes punching and inserting, the vertical cylinder row A190 is pushed into the feeding station 104 along the workbench 114 until being blocked by the blocking strip 137, and the feeding lower clamp 112 moves upwards and is matched with the feeding upper clamp 113 up and down to clamp the vertical cylinder row A190. When the feeding mobile platform 110 rises, the vertical cylinder row A190 is driven to be separated from contact with the cylinder row bearing strip 101, so that the phenomenon that fireworks roll in the same way due to friction is avoided.

The molding station 105 includes a liftable molding moving platform 115, and a molding clamp and a molding mechanism are disposed on the molding moving platform 115.

In an example, the forming clamp includes a lower end clamp and an upper end clamp: a plurality of positioning bolts 1162 are fixedly arranged on the positioning strip 1161 of the lower end clamp, and the lower end clamp cylinder 1163 drives the positioning bolts 1162 to be correspondingly inserted into the lower end holes of each firework barrel of the vertical barrel row A190 through the positioning strip 1161. The upper clamp cylinder 1171 drives the upper clamp down to cooperatively clamp the vertical cylinder row a190 up and down.

The forming mechanism includes a drive plate 118 and a plurality of forming assemblies arranged side-by-side:

the transmission plate 118 is provided with a plurality of guide sliding grooves 119, and each guide sliding groove 119 is distributed corresponding to the arrangement structure of each firework cylinder in the fan-shaped cylinder row, which means that the distribution structure of each guide sliding groove 119 on the transmission plate 118 corresponds to the arrangement structure of each firework cylinder in the special-shaped cylinder row. In this example, the special-shaped cylinder row is a fan-shaped cylinder row, and then the number of the guide sliding grooves 119 is the same as that of the firework cylinders; next, each of the guide grooves 119 has the same distribution angle as the corresponding firework barrel, so that the guide grooves 118 are also distributed in a fan shape on the transmission plate 118. However, the length, width, etc. of the guide chute are not required to be consistent with those of the firework cylinder. In other embodiments, the special-shaped cylinder rows are V-shaped cylinder rows, W-shaped cylinder rows, left-inclined cylinder rows, right-inclined cylinder rows and the like, and the guide sliding grooves are correspondingly distributed on the transmission plate. And will not be described in detail.

Each molding assembly includes a slider 121 movably sleeved on the guide post 120, and a connecting piece at the bottom end of the slider 121 is movably sleeved in one guide chute 119, and in an example, the connecting piece includes a rotating shaft 1221 fixedly connected to the bottom end of the slider 121, and a bearing 1222 mounted on the rotating shaft 1221 is movably sleeved in the guide chute 119.

The slider 121 is provided with a cylinder positioning member. In the example, the cylinder positioning member is an arc-shaped groove 124, the arc-shaped groove 124 is hinged on the sliding block 121 through a hinge shaft 123, and the arc-shaped groove 124 is disposed corresponding to the upper end of the upright cylinder row a190.

The working principle of the forming mechanism is as follows:

when the forming moving platform 115 rises, the forming mechanism is driven to rise, the side wall of each arc-shaped groove 124 rising along with the forming moving platform is inserted between adjacent firework cylinders in the vertical cylinder row A190, and each arc-shaped groove 124 correspondingly receives and positions the upper end of each firework cylinder. The driving plate 118 is connected to the forming cylinder 125 to reciprocate linearly between an initial position and a working position. When the driving plate 118 is at the initial position, the bearings 1222 are positioned at the head ends of the guide grooves 119. When the transmission plate 118 reaches the working position, the bearing 1222 is located at the tail end of each guide chute 119, so as to further drive each sliding block 121 to slide along the axial direction of the guide pillar 120, and each sliding block 121 drives the upper end of the firework barrel to swing through the arc-shaped groove 124 to obtain a fan-shaped barrel row 191. The arc-shaped groove 124 rotates along the hinge shaft 123 as the upper end of the cartridge swings.

In the process, the forming mechanism can act only by lifting the distance of 0.3-1 firework cylinder diameter, the forming period is greatly shortened compared with the prior art, and the working efficiency is effectively improved in continuous production.

In an example, the third station 106 includes a paper feed mechanism and a glue applicator mechanism, and the row of carrier tapes 101 between the forming station 105 and the third station 106 have recessed areas. The paper feeding mechanism comprises a paper roll 126 positioned below the barrel row carrier bar 101, and further comprises a paper guide roll 127 positioned in the concave area, and a paper tape 128 unwound from the paper roll 126 is laid on the barrel row carrier bar 101 by bypassing the paper guide roll 127. The glue applicator mechanism includes a glue box 129 located in the recessed area, and glue applicator rollers 130 are disposed within the glue box 129. In the recessed area, the guide roller 127 is adjacent to the third station 106 and the glue cartridge 129 is adjacent to the forming station 105. During the process of the fan-shaped cylinder row 191 entering the third station 106 from the forming station 105, the glue applicator roller 130 abuts against the bottom surface of the fan-shaped cylinder row 191 for glue application. After entering the third station 106, the fan-shaped cylinder 191 is glued with the paper tape 128 to obtain a paper-sticking fan-shaped cylinder 192, and the pasting process of the isolation paper layer is completed. The lifting pressing bar 102 is matched with the cylinder row bearing bar 101 up and down to clamp and press when descending, so that the gluing is firmer.

In the example, the third station 106 includes a third movable platform 131 that can be lifted, and a third clamp 132 is disposed on the third movable platform 131 to clamp the sector-shaped paper-sticking cylinder 192 up and down; the third moving platform 131 moves synchronously with the feeding moving platform 110 and the forming moving platform 115, and when the third moving platform 131 ascends, the paper pasting fan-shaped cylinder row 192 is driven to be separated from the cylinder row bearing bar 101. The third moving platform 131 is reset after moving from the third station 106 to the fourth station 107, and the sticker fan-shaped cylinder row 192 is sent to the fourth station 107 for glue curing.

The fourth station 107, the fifth station 108 and the sixth station 109 are all provided with a lifting moving platform, and the moving platform is provided with a clamp for clamping the cylinder row up and down, so that the cylinder row can be conveniently and sequentially conveyed to the next station, and the conveying working principle is the same as that of the previous station, and the repeated description is omitted. The moving platform is provided with a heating plate 133 of the drying cylinder row. The plurality of heating plates 133 heat and solidify the glue for a plurality of times, thereby shortening the period of each station movement, and further accelerating the working efficiency while ensuring the solidification of the glue. Meanwhile, the fourth station 107, the fifth station 108 and the sixth station 109 can also be used as standby stations, and work such as wire hole dispensing, wire tape sealing, cylinder row bonding and reinforcing paper board can be performed according to requirements.

In the example, each mobile platform device is synchronously driven by a long range driving cylinder 135 on a directional moving frame 134 to synchronously reciprocate along a cylinder row carrier bar between stations. The directional moving frame 134 is driven by platform lifting cylinders 136 at two ends of the frame to synchronously lift. The movable driving mechanism and the lifting driving mechanism are prevented from being arranged at each station, the equipment structure is effectively simplified, and the synchronicity of the movement and the lifting movement of each station is ensured.

The vertical cylinder rows 190 with the holes punched and inserted continuously enter the feeding station 104, and each vertical cylinder row 190 sequentially passes through six stations step by step to finally manufacture the glue-cured paper-sticking fan-shaped cylinder row 192. In the example, a row collection mechanism 138 is further disposed behind the sixth station 109, and the fan-shaped rows 192 of dry decals sent out by the sixth station are sequentially collected by a step-by-step lifting platform. A paper cutting mechanism 139 is provided between the sixth station 109 and the row of collection mechanisms 138 to cut the web 128.

Example 2: another way of finishing the bonding process of the separator paper layer according to the invention, see fig. 17, comprises a paper roll 202 below a cylinder row carrier 201, a glue box 203 being provided beside the paper roll 202, and glue rollers being provided in the glue box 203. And a paper guide roller 204, in which the paper guide roller 204 is positioned at the end of the barrel row carrier 201, the paper tape 205 unwound from the paper roll 202 is glued by the glue application roller and then laid on the barrel row carrier 201 by bypassing the paper guide roller 204, and the paper tape 205 is cut off by the paper cutting mechanism 206 sequentially through each station. The separator paper layer can also be automatically adhered below the fan-shaped cylinder row.

The strip 205 is glued to the row 208 of upright cylinders at the feeding station 207, and since the strip 205 has a width less than the width of the row 208 of upright cylinders, there is no strip below the upper end of the row 208 of upright cylinders, and at the forming station 209 the cylinder positioning members can also position the upper end of each cartridge in the row 208 of upright cylinders.

Meanwhile, although the paper tape 205 is glued with the vertical barrel row 208, the glue is not cured, and the barrel positioning piece can drive the firework barrel to swing, so that the fan-shaped barrel row 210 is obtained.

The other components are the same as those in embodiment 1, and will not be described again.

In other embodiments, the paper guide roller may be located in a recessed region of the row carrier strip between the infeed and forming stations. The operation is similar to that of example 1.

Example 3: referring to fig. 18, the cylinder positioning member is a needle body 302 fixedly mounted on the slider 301, and when the forming mechanism is lifted, each needle body 302 lifted up is inserted between adjacent firework cylinders in the vertical cylinder row, and the two adjacent needle bodies 302 respectively and correspondingly position the upper ends of the firework cylinders. When each sliding block 301 slides along the guide post 303, the needle body 302 drives the upper end of the firework barrel to swing. In this example, needle 302 need not be rotated. The other components are the same as those in embodiment 1, and will not be described again.
