Description

Technical Field

[0001] This invention relates to a molding device for irregularly shaped tube arrays of irregularly shaped combined fireworks. Background Technology

[0002] Combination fireworks typically consist of several paper firework tubes arranged in a single row, called a tube array. Then, the tubes in the array are perforated and fitted with fuses. This involves punching holes in each tube and inserting fuses into these holes, connecting the tubes to form a ignition link. Currently, tube arrays are manufactured in this manner. Figure 1 The vertical tube array shown has its individual firework tubes arranged in a parallel axis. Several vertical tube arrays are then stacked and assembled into a block (called a "combination unit"), resulting in a product called a vertical combination firework. The firework tube's internal cavity contains propellant and effect components, and is ignited by a fuse.

[0003] The equipment used to complete the above-mentioned assembly of fireworks tubes is commonly referred to in the industry as a "firework assembly machine" or "firework assembly machine." It is a relatively mature and widely used type of fireworks machinery. The existing workflow of the assembly machine is as follows: a feeding and discharging system feeds multiple fireworks tubes onto a worktable in the required quantity, arranging them in rows; a pushing device then pushes the rows of tubes on the worktable out in a direction parallel to the central axis of the fireworks tubes, conveying them to the punching and insertion station under the clamping of the worktable and the conveyor rollers; a moving insertion system, including a lead wire conveying mechanism, completes the punching and insertion process; then, adhesive is applied to the sides and top of the fireworks tubes in the row; under the push of the rear rows, the front rows on the worktable sequentially enter the forming system, stacking and gluing multiple rows together to form a block-like whole. Examples include "A Firework Assembly Machine" disclosed in Chinese invention patent document CN 102538597A; and "A Firework Tube Punching and Insertion Device" disclosed in Chinese invention patent document CN105486179A.

[0004] However, besides upright combination fireworks, existing products also include irregularly shaped combination fireworks, which are fireworks products assembled from stacked irregularly shaped tubes. In this invention, the end of the upright or irregularly shaped tube array near the perforated insertion part is referred to as the lower end of the tube array or firework tube, and the end away from the perforated insertion part is referred to as the upper end of the tube array or firework tube. The arrangement structure of the firework tubes in the irregularly shaped tube array is as follows: Figure 2 The sector shown Figure 3 The W-shaped pattern shown Figure 4 The V-shape shown Figure 5 The left-leaning type shown Figure 6 The right-leaning type shown Figure 7The five-finger type cylinder row and the like is shown; unlike the vertical cylinder row, the special-shaped cylinder row has a certain oblique included angle (launching oblique angle) between the fireworks cylinders, the lower ends of the fireworks cylinders are close to each other, and there is a cylinder spacing between the upper ends of adjacent fireworks cylinders. Therefore, the current group pot equipment can only complete the production of vertical combined fireworks, and cannot process special-shaped fireworks products.

[0005] In the prior art, a Chinese invention patent document with the application publication number CN 110986690 A discloses "a special-shaped arrangement fireworks cylinder production device and a production method thereof", and the vertical cylinder row with completed punching and inserting is processed into a special-shaped arrangement by a fireworks cylinder special-shaped arrangement mechanism. The fireworks cylinder special-shaped arrangement mechanism includes a fixed support and a fireworks cylinder groove. The fireworks cylinder groove is connected with the fixed support at one end and is arranged along the width direction of the fixed support. The connection position is a pivot point at which the fireworks cylinder groove can rotate left and right. A wedge block that can move up and down is arranged at the gap between adjacent fireworks cylinder grooves. The wedge block is used to push the fireworks cylinder groove to rotate and swing by a certain angle and then position the fireworks cylinder groove, so that the fireworks cylinder is arranged in a special shape.

[0006] The main disadvantage of the prior art is that when the multiple wedge blocks are inserted into the gaps between the multiple adjacent fireworks cylinder grooves, the gaps are in a constantly changing and uncertain state due to the swinging of each fireworks cylinder groove. The rising of the multiple wedge blocks and the swinging of the multiple fireworks cylinder grooves are prone to motion interference, resulting in low work reliability. At the same time, there is a problem of low production efficiency of special-shaped cylinder rows. The main reason is that the feeding and forming of the vertical cylinder row can only be completed at the same station. After the cylinder row is fed along the fireworks cylinder axis direction from the front end to the rear end of the fireworks cylinder groove, the special-shaped arrangement can be performed. The long feeding stroke leads to a long forming cycle, resulting in low work efficiency. SUMMARY

[0007] In order to solve the above-mentioned disadvantages, the technical problem to be solved by the present application is to provide a special-shaped combined fireworks cylinder row forming device for processing the vertical cylinder row with completed punching and inserting into a special-shaped cylinder row, thereby effectively improving the work reliability and production efficiency.

[0010] The forming moving platform is lifted to lift the forming mechanism, and each cylinder positioning piece of the forming mechanism is used to position the upper end of each firework cylinder of the upright cylinder array; the transmission plate is connected to a driving mechanism to make linear reciprocating motion between an initial position and a working position; when the transmission plate is located at the initial position, the connecting piece is located at the head end of each guide sliding groove; when the driving mechanism drives the transmission plate to reach the working position, the connecting piece is located at the tail end of each guide sliding groove; each guide sliding groove drives each sliding block to slide along the guide column through the connecting piece, and each sliding block drives the upper end of the firework cylinder to swing through the cylinder positioning piece to obtain the special-shaped cylinder array;

[0011] The feeding moving platform and the forming moving platform are synchronously reciprocated along the cylinder array bearing strip between the stations.

[0012] The working process of the device comprises the following steps:

[0013] S1: the feeding moving platform and the forming moving platform are simultaneously lifted; the upright cylinder array A is separated from the cylinder array bearing strip in the feeding station; the upper end of each firework cylinder of the upright cylinder array A is positioned by each cylinder positioning piece of the forming moving platform, and the transmission plate is moved to the working position to obtain the special-shaped cylinder array;

[0014] S2: the feeding moving platform and the forming moving platform are synchronously moved: the forming moving platform with the special-shaped cylinder array leaves the forming station and enters the third station, and the feeding moving platform with the upright cylinder array A moves from the feeding station to the forming station;

[0015] S3: the feeding moving platform and the forming moving platform are simultaneously lowered, and the lifting type pressing strip is lowered to press the upright cylinder array A and the special-shaped cylinder array in cooperation with the cylinder array bearing strip;

[0016] S4: the feeding clamp releases the upright cylinder array A; the forming clamp releases the special-shaped cylinder array, and the transmission plate returns to the initial position; the feeding moving platform and the forming moving platform are synchronously reversely moved to reset;

[0020] In the combined firework display, the ignition of each firework cylinder must be performed according to the ignition order determined by the transfer fuse, otherwise the display effect is destroyed; the firework cylinder of the previous cylinder row is sequentially ignited and then the transfer is performed to the next cylinder row; in order to avoid the phenomenon of cross-fire between the cylinder rows assembled in layers and destroy the ignition order, a separation paper layer is also glued on the side surface of each cylinder row before the group is formed. In order to avoid the change of the transfer performance of the fuse caused by the glue wetting the fuse, the separation paper layer cannot be pasted on the upper surface of the cylinder row where the hole is punched and the fuse is inserted, but must be pasted on the lower surface of the cylinder row. In the Chinese invention patent document with the application publication number CN 110986690 A, due to the structural limitation, the separation paper layer cannot be automatically pasted on the lower surface of the cylinder row, but only can be pasted on the upper surface of the cylinder row.

[0053] Example 1: Refer to the attached drawings Figures 1-16 , reflecting a specific structure of the present application. The special-shaped cylinder row forming equipment of the special-shaped combination firework processes the straight cylinder row with completed punching and inserting of the existing firework group pot machine as the processing object, and in the example, processes the straight cylinder row into a fan-shaped cylinder row. In other embodiments, the processing object can also be a straight cylinder row without completed punching and inserting.

[0054] The cylinder row bearing strip 101 is fixed on the frame of the equipment, and the cylinder row bearing strip 101 is arranged along the length direction of the equipment. The lifting pressing strip 102 is arranged above the cylinder row bearing strip 101, and the lifting pressing strip 102 is driven to lift by the pressing strip air cylinder 103 at both ends of the frame.

[0055] The feeding station 104, the shaping station 105, and the third station 106 are sequentially and parallelly arranged along the cylinder row bearing strip 101. In the example, the fourth station 107, the fifth station 108, and the sixth station 109 are also sequentially and parallelly arranged.

[0056] The feeding station 104 comprises a liftable feeding moving platform 110, which 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 punching and inserting of the vertical cylinder row A190, the vertical cylinder row A190 is pushed into the feeding station 104 along the workbench surface 114 until being blocked by the blocking strip 137, and the feeding lower clamp 112 is raised to cooperate with the feeding upper clamp 113 to clamp the vertical cylinder row A190. When the feeding moving platform 110 is lifted, the vertical cylinder row A190 is separated from the cylinder row bearing strip 101 to avoid friction and disorder of the fireworks.

[0057] The forming station 105 comprises a liftable forming moving platform 115, which is provided with a forming clamp and a forming mechanism.

[0058] In the example, the forming clamp comprises a lower end clamp and an upper end clamp. A plurality of positioning pins 1162 are fixed on the positioning strip 1161 of the lower end clamp, and a lower end clamp cylinder 1163 drives the positioning pins 1162 to be inserted into the lower end holes of the fireworks cylinders of the vertical cylinder row A190. The upper end clamp cylinder 1171 drives the upper end clamp to be lowered to clamp the vertical cylinder row A190.

[0059] The forming mechanism comprises a transmission plate 118 and a plurality of parallelly arranged forming assemblies.

[0060] The transmission plate 118 is provided with a plurality of guide sliding grooves 119, which are distributed according to the arrangement structure of the fireworks cylinders of the fan-shaped cylinder row. That is, the distribution structure of the guide sliding grooves 119 on the transmission plate 118 corresponds to the arrangement structure of the fireworks cylinders of the special-shaped cylinder row. In this example, the special-shaped cylinder row is a fan-shaped cylinder row, so that the number of the guide sliding grooves 119 is the same as that of the fireworks cylinders, and the distribution angle of each guide sliding groove 119 is the same as that of the corresponding fireworks cylinder, so that the guide sliding grooves 118 are also distributed in a fan shape on the transmission plate 118. However, the length and width of the guide sliding grooves do not have to be the same as those of the fireworks cylinders. In other embodiments, when the special-shaped cylinder row is a V-shaped cylinder row, a W-shaped cylinder row, a left-leaning cylinder row, or a right-leaning cylinder row, the guide sliding grooves are also correspondingly distributed on the transmission plate. Details are not described herein.

[0061] Each forming assembly comprises a sliding block 121 movably sleeved on a guide column 120, and a connecting piece at the bottom end of the sliding block 121 movably sleeved in a guide sliding groove 119. In the example, the connecting piece comprises a rotating shaft 1221 fixed at the bottom end of the sliding block 121, and a bearing 1222 movably sleeved in the guide sliding groove 119 and installed on the rotating shaft 1221.

[0062] The slider 121 is provided with a cylinder positioning member. In the example, the cylinder positioning member is an arc-shaped groove body 124, which is hinged to the slider 121 through a hinge shaft 123, and which corresponds to the upper end of the upright cylinder row A190.

[0063] The working principle of the forming mechanism is as follows:

[0064] When the forming moving platform 115 rises, the forming mechanism rises, and the sidewalls of the arc-shaped groove bodies 124 inserted between adjacent firework cylinders in the upright cylinder row A190 rise, and each arc-shaped groove body 124 corresponds to the upper end of each firework cylinder. The transmission plate 118 connects the forming cylinder 125 to make linear reciprocating motion between the initial position and the working position. When the transmission plate 118 is located at the initial position, the bearing 1222 is located at the head end of each guide sliding groove 119. When the transmission plate 118 reaches the working position, the bearing 1222 is located at the tail end of each guide sliding groove 119, further driving each slider 121 to slide along the axis of the guide column 120, and each slider 121 drives the upper end of the firework cylinder to swing to obtain the fan-shaped cylinder row 191 through the arc-shaped groove body 124. When the upper end of the firework cylinder swings, the arc-shaped groove body 124 rotates along the hinge shaft 123.

[0065] In the above process, the forming mechanism only needs to rise by a distance of 0.3-1 firework cylinder diameter, and the transmission plate 118 can act, so that the forming cycle is greatly shortened compared with the prior art, and the working efficiency is effectively improved in continuous production.

[0066] In the example, the third station 106 includes a paper feeding mechanism and a glue applying mechanism, and the cylinder row bearing strip 101 between the forming station 105 and the third station 106 has a recessed area. The paper feeding mechanism includes a paper roll 126 located below the cylinder row bearing strip 101, and a paper guide roller 127 located in the recessed area, and the paper tape 128 unwound from the paper roll 126 is laid on the cylinder row bearing strip 101 through the paper guide roller 127. The glue applying mechanism includes a glue box 129 located in the recessed area, and the glue box 129 is provided with a glue applying roller 130. In the recessed area, the paper guide roller 127 is close to the third station 106, and the glue box 129 is close to the forming station 105. During the process that the fan-shaped cylinder row 191 enters the third station 106 from the forming station 105, the glue applying roller 130 abuts against the bottom surface of the fan-shaped cylinder row 191 to apply glue. After the fan-shaped cylinder row 191 enters the third station 106, the fan-shaped cylinder row 191 is glued with the paper tape 128 to obtain a paper-pasted fan-shaped cylinder row 192, and the paste of the isolation paper layer is completed. When the lifting type pressing strip 102 descends, it is clamped and pressed with the cylinder row bearing strip 101 to make the gluing more firm.

[0067] In the example, the third station 106 comprises a third movable platform 131 that can be lifted, and the third movable platform 131 is provided with a third clamp 132 that clamps the fan-shaped paper tube row 192 up and down. The third movable platform 131 moves synchronously with the feeding movable platform 110 and the forming movable platform 115, and when the third movable platform 131 is lifted, the fan-shaped paper tube row 192 is separated from the contact with the tube row bearing strip 101. After the third movable platform 131 moves from the third station 106 to the fourth station 107, the third movable platform 131 is reset, and the fan-shaped paper tube row 192 is sent to the fourth station 107 for glue curing.

[0068] The fourth station 107, the fifth station 108, and the sixth station 109 are provided with movable platforms that can be lifted, and the movable platforms are provided with clamps that clamp the tube row up and down, so as to facilitate the tube row to be sequentially transported to the next station. The working principle of the transportation is the same as that of the previous stations, and thus is not described herein again. The movable platforms are provided with heating plates 133 that dry the tube row. The plurality of heating plates 133 dry the glue in multiple times, so as to shorten the period of each station movement, and to ensure the glue curing while further accelerating the working efficiency. Meanwhile, the fourth station 107, the fifth station 108, and the sixth station 109 can also be used as standby stations, and can be used for the work of dispensing glue in the lead hole, sealing the lead with adhesive tape, and pasting the tube row with reinforcing paper, and the like.

[0069] In the example, each movable platform device is synchronously driven by a long-range driving cylinder 135 on a directional moving frame 134, and moves reciprocally along the tube row bearing strip between the stations. The directional moving frame 134 is synchronously lifted by the platform lifting cylinders 136 at both ends of the frame. The movable platform device avoids setting a moving driving mechanism and a lifting driving mechanism at each station, effectively simplifies the structure of the equipment, and ensures the synchronism of the movement and the lifting movement of each station.

[0070] The straight tube row 190 that is completed with the punching and the lead insertion continuously enters the feeding station 104, and each straight tube row 190 sequentially and gradually passes through the six stations, and is finally processed into the paper fan-shaped tube row 192 that is cured with glue. In the example, the sixth station 109 is further provided with a tube row collecting mechanism 138 that collects the dried paper fan-shaped tube row 192 sent out by the sixth station in sequence through the lifting platforms in stages. The sixth station 109 and the tube row collecting mechanism 138 are provided with a paper cutting mechanism 139 that cuts the paper tape 128.

[0071] Embodiment 2: Another way to reflect the pasting processing of the isolation paper layer completed by the present application, see FIG. 6. Figure 17, including the paper roll 202 below the cylinder row bearing strip 201, the glue box 203 beside the paper roll 202, and the glue roller in the glue box 203. It also includes the paper guide roller 204, in the example, the paper guide roller 204 is located at the end of the cylinder row bearing strip 201, the paper tape 205 unwound from the paper roll 202 is glued by the glue roller and then winds around the paper guide roller 204 and is laid on the cylinder row bearing strip 201, and the paper tape 205 is cut by the paper cutting mechanism 206 in turn. The isolation paper layer can also be automatically pasted under the fan-shaped cylinder row.

[0072] The paper tape 205 is glued with the upright cylinder row 208 at the feeding station 207, since the width of the paper tape 205 is less than the width of the upright cylinder row 208, the lower part of the upper end of the upright cylinder row 208 is not covered by the paper tape, at the forming station 209, the cylinder positioning member can also position the upper end of each firework cylinder in the upright cylinder row 208.

[0073] At the same time, although the paper tape 205 has been glued with the upright cylinder row 208, the glue has not yet solidified, the cylinder positioning member can also swing the firework cylinder, and then obtain the fan-shaped cylinder row 210.

[0074] The rest is the same as example 1 and will not be repeated.

[0075] In other embodiments, the paper guide roller can be located in the recessed area of the cylinder row bearing strip between the feeding station and the forming station. Its working mode is similar to that of example 1.

[0076] Example 3: another structure of the cylinder positioning member of the application, see the attached Figure 18 , the cylinder positioning member is a needle body 302 fixed on the sliding block 301, when the forming mechanism rises, each needle body 302 inserted between the adjacent firework cylinders in the upright cylinder row rises with it, and the adjacent two needle bodies 302 correspond to positioning the upper end of each firework cylinder respectively. When each sliding block 301 slides along the guide column 303, the needle body 302 swings the upper end of the firework cylinder. In this example, the needle body 302 does not need to rotate. The rest is the same as example 1 and will not be repeated.
