[0001] The utility model relates to the technical field of firework cylinder production, and particularly relates to a rising and flipping punching device. Background Art

[0002] During the processing of fireworks cylinders, punching is one of the indispensable key steps. The purpose of punching is to insert the ignition fuse to ensure that the fireworks can take off and explode in a predetermined manner during the fireworks display, so as to achieve the expected visual effect. At present, the punching techniques for fireworks cylinders are mainly divided into manual punching and mechanical punching. Although manual punching is flexible, it has problems such as low production efficiency, high labor intensity, and high labor costs. Moreover, due to human factors, it is difficult to guarantee the punching quality and consistency. With the development of automation technology, mechanical punching has gradually replaced some manual punching. However, most of the existing mechanical punching equipment has problems such as low production efficiency, poor safety, and damage to the fireworks cylinders. In view of the above problems.

[0007] Further, the flipping bucket includes a first side plate, a second side plate, an upper baffle, a side baffle, mounting holes, and a buckle unit. The upper baffle is vertically and fixedly connected to the upper ends of the first side plate and the second side plate. The side baffle is vertically and fixedly connected to the right ends of the first side plate and the second side plate. A first through hole is opened on the upper baffle, and a second through hole is opened on the side baffle; two mounting holes are symmetrically opened at the lower ends of the first side plate and the second side plate, and the buckle unit is movably installed in the mounting holes.

[0008] Furthermore, the buckle unit includes a buckle, a round shaft, a fixing plate with a shaft hole, and a first spring. The buckle is fixedly connected to the round shaft. The two ends of the round shaft are respectively movably installed in the shaft holes of the fixing plate. One end of the first spring is connected to the buckle, and the other end of the first spring is connected to the tipping bucket.

[0009] Furthermore, the buckle is composed of a rotating part and a supporting part. The supporting part is located at the upper right of the rotating part. The rotating part and the supporting part are fixedly connected as a whole. The buckle is located in the mounting hole, and the supporting part of the buckle extends into the tipping bucket.

[0010] Furthermore, the cross-section of the supporting part is a right triangle.

[0011] Furthermore, the punching mechanism is composed of a second bracket, a fixing plate, several punching needles, a punching plate, a baffle, and a punching oil cylinder. The fixing plate is fixedly installed at the top of the second bracket. The punching oil cylinder is installed at the center of the fixing plate. The output end of the punching oil cylinder penetrates the fixing plate and extends to one side of the punching plate. Several punching needles are fixedly installed below the punching plate at equal intervals. A baffle is arranged below the punching needles, and needle holes corresponding to the punching needles are formed in the baffle.

[0012] Furthermore, a lifting mechanism is installed on the right side of the punching mechanism. The lifting mechanism is composed of a third bracket, a lifting cylinder, and a lifting plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the operator first places the firework cylinder upright with the opening facing up and the bottom facing down on the rack, the pushing mechanism 1 pushes the firework cylinder to the right, causing the firework cylinder to enter the tipping bucket. When the firework cylinder moves upward under the action of the lifting mechanism, the pushing buckle rotates. When the firework cylinder completely enters the tipping bucket and the upper surface of the firework cylinder collides with the upper baffle of the tipping bucket, the buckle rotates and pops out of the mounting hole under the action of spring 1 and resets, thus holding the bottom of the firework cylinder. The tipping drive unit operates to drive the tipping bucket to rotate 180°, making the bottom of the firework cylinder face up. The pushing mechanism 2 operates to smoothly send it into the punching mechanism for punching operation. The entire tipping process is smooth and fast. During the tipping process of the firework cylinder, there is no need to rub against the rack, and it completes a 180° free rotation in the air, with extremely high safety. Under the action of the buckling unit, the firework cylinder does not need to be strongly clamped, avoiding damage and extrusion of the firework cylinder, and further improving safety. On the one hand, the present utility model greatly improves the safety of tipping and punching the firework cylinder, and on the other hand, effectively improves the punching efficiency.

[0016] 2. For the rising and tipping punching device provided by the present utility model, when punching the firework cylinder, the punching oil cylinder controls the precise positioning of the punching plate and the punching needle first slowly and then quickly, and can accurately and quickly complete the punching operation, improving the punching quality. In addition, due to the setting of the baffle, it can effectively prevent the bad phenomenon that the punching needle brings up the firework cylinder when the punching plate rises, improving the stability and safety during the punching operation.

[0017] 3. For the rising and tipping punching device provided by the present utility model, when the pushing mechanism 1 pushes the firework cylinder on the rack forward, the firework cylinder will pass through the scraping mechanism, and the scraper will remove burrs, impurities, etc. on the upper surface of the firework cylinder, making it cleaner.

Preferably, in this embodiment, the first pushing mechanism 3 adopts a pneumatic cylinder, and the first pushing mechanism 3 is used to push the fireworks cylinder body to move to the right. At the right end of the frame 2, a rising and flipping mechanism 5 is installed. The rising and flipping mechanism 5 is used to lift the fireworks cylinder body 1 upward and perform a 180° flip, so that the bottom surface of the fireworks cylinder body 1 faces upward. At the upper left side of the rising and flipping mechanism 5, a second pushing mechanism 4 is provided. The second pushing mechanism 4 is a hydraulic cylinder, a pneumatic cylinder or an electric push rod. At the right side of the rising and flipping mechanism 5, a punching mechanism 6 is installed.

The first pushing mechanism 3 and the second pushing mechanism 4 are pneumatic cylinders, hydraulic cylinders or electric push rod mechanisms.

[0028] As Figure 2 shown, the rising and flipping mechanism 5 includes a first support 51, a flipping bucket 52, a flipping drive unit 53, a jacking mechanism 54, and a bearing seat 55. The first support 51 is made of angle steel, square steel, steel rods or other profiles and is connected or welded by bolts. Below the first support 51, a jacking mechanism 54 is provided.

[0029] As Figure 3 、 Figure 4As shown in the figure, the tipping bucket 52 includes a first side plate 521, a second side plate 522, an upper baffle 523, a side baffle 525, mounting holes 527, and a buckle unit. The first side plate 521, the second side plate 522, the upper baffle 523, and the side baffle 525 are all made of steel plates or metal plates. The upper baffle 523 is vertically welded to the upper ends of the first side plate 521 and the second side plate 522. The first side plate 521 and the second side plate 522 are parallel to each other. A first through hole 524 is formed in the upper baffle 523. The side baffle 525 is vertically welded to the right ends of the first side plate 521 and the second side plate 522. A second through hole 526 is formed in the side baffle 525. When the fireworks cylinder 1 and the tipping bucket 52 are flipped by 180°, the upper baffle 523 is flipped from the upper position of the tipping bucket 52 to the lower position of the tipping bucket 52, and the fireworks cylinder 1 is flipped by 180°, so that the bottom surface of the fireworks cylinder 1 faces upward and the top surface faces downward. The side baffle 525 is flipped from the right side position of the tipping bucket 52 to the left side position of the tipping bucket 52. The second pushing mechanism 4 pushes the flipped fireworks cylinder 1 to move to the right through the second through hole 526 on the left side baffle 525. The inner cavity of the tipping bucket 52 is larger than the outer dimension of the fireworks cylinder 1. It should be noted that the upper baffle 523 and the side baffle 525 can also be replaced by a number of connecting rods.

[0030] Two mounting holes 527 are symmetrically formed at the lower ends of the first side plate 521 and the second side plate 522, and a buckle unit is movably installed in the mounting holes 527. The buckle unit includes a buckle 528, a round shaft 529, a fixed plate 530 with a shaft hole, and a first spring 531. There are two fixed plates 530 with shaft holes, which are welded to the side plates of the tipping bucket 52 in parallel. The buckle 528 is fixedly connected to the round shaft 529, and the two ends of the round shaft 529 are respectively movably installed in the shaft holes of the fixed plate. One end of the first spring 531 is connected to the buckle 528, and the other end of the first spring 531 is connected to the side plate of the tipping bucket 52.

[0031] The buckle 528 is composed of a rotating part 533 and a supporting part 532. The circular shaft 529 of the buckle unit passes through the rotating part 533 and is welded to the rotating part 533. The supporting part 532 is located at the upper right of the rotating part 533. The rotating part 533 and the supporting part 532 are fixedly connected as a whole. The cross-section of the supporting part 532 is in the shape of a "triangle". Preferably, the cross-section of the supporting part is in the shape of a "right triangle". The buckle 528 is located in the mounting hole 527. The supporting part 532 of the buckle 528 extends into the tipping bucket 52, and the upper surface of the supporting part 532 remains horizontal in the stationary state. When the fireworks cylinder 1 moves upward under the action of the lifting mechanism 54, it pushes the buckle 528 to rotate along the circular shaft 529 and the shaft hole of the fixing plate. The supporting part 532 of the buckle 528 rotates into the mounting hole 527. When the fireworks cylinder 1 completely enters the tipping bucket 52 and the upper surface of the fireworks cylinder 1 collides with the upper baffle of the tipping bucket 52, the buckle 528 rotates reversely and resets from the mounting hole 527 towards the inside of the tipping bucket 52 under the action of the first spring 531, so as to support the bottom of the fireworks cylinder 1.

The fixing plate 62, the punching plate 64, and the baffle 65 are all made of steel plates or other metal plates. The fixing plate 62 is fixedly installed at the top of the second bracket 61 by means of bolt connection or welding. A punching oil cylinder 66 is installed at the center position of the fixing plate 62. The output end of the punching oil cylinder 66 penetrates through the fixing plate 62 and extends to one side of the punching plate 64. The push rod of the punching oil cylinder 66 is fixedly connected to the punching plate 64 by welding or other means. A plurality of punching needles 63 are fixedly installed below the punching plate 64 at equal intervals.

The lifting mechanism 7 is composed of a third bracket 71, a lifting cylinder 72, and a lifting plate 73. The lifting cylinder 72 is arranged at the center below the third bracket 71, and the lifting plate 73 is arranged above the third bracket 71. When punching the fireworks cylinder body 1, through the control of the punching oil cylinder 66 to first slow down and then speed up, the precise positioning of the punching plate 64 and the punching needle 63 can be driven, and the punching operation can be completed precisely and quickly, improving the punching quality. In addition, due to the setting of the baffle 65, the adverse phenomenon that the punching needle 63 brings up the fireworks cylinder body 1 when the punching plate 64 rises can be effectively prevented, improving the stability and safety during the punching operation.

[0034] Preferably, as Figure 1 shown, a plurality of scraping mechanisms 8 are installed above the left side of the frame 2.
