Description

Technical Field

[0001] This utility model belongs to the field of firecracker special equipment manufacturing, and in particular relates to a firecracker sealing glue injection machine. Background Technology

[0002] With the increasing demands for production safety, product quality, and production efficiency in the fireworks and firecrackers industry, the production process of firecrackers, as a traditional folk product, includes multiple stages such as tube making, powder filling, sealing, and weaving. Among these, the injection of adhesive in the sealing process is particularly critical, directly affecting the product's sealing performance, safety, and ignition effect.

[0003] However, firecracker production has long relied on manual operation and small-scale workshops, making it a typical labor-intensive industry. In the sealing and glue application stage, manual application of glue to the firecracker tube opening using brushes or simple tools is commonly used. This not only results in uneven glue control, incomplete sealing, and unstable product quality, but also leads to low production efficiency and high labor intensity, making it difficult to adapt to the actual needs of large-scale production and standardized operations.

[0004] Therefore, there is a particular need for a firecracker sealing glue injection machine to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional firecracker sealing, which relies on manual glue application, resulting in low efficiency, uneven glue application, poor sealing, and unstable quality, and is difficult to meet the needs of large-scale and standardized production, this utility model provides a firecracker sealing glue injection machine.

A piston rod 5 is slidably mounted inside each syringe 3. The upper end of the piston rod 5 extends to the outside of the syringe 3, and the lower end is fixedly connected to a piston block 51. The piston block 51 slides and seals with the inner wall of the syringe 3. The piston block 51 is made of sealing rubber. The upper end of the leftmost syringe 3 in each row is fixedly mounted. A connecting pipe 6 is fixedly connected, and a flow valve 7 is installed on each connecting pipe 6 to control the on / off state. The mounting plate 10 is bolted to the left side of the base frame 1. The liquid storage tank 8 is bolted to the left side of the mounting plate 10, and two parallel liquid inlets 81 are fixedly connected to its top. The water pump 91 is bolted to the bottom of the liquid storage tank 8, and its liquid extraction end is connected to the inside of the liquid storage tank 8. The diverter pipe 9 is fixedly connected between the liquid outlet end of the water pump 91 and the twelve connecting pipes 6 to realize the synchronous supply of glue to the twelve rows of syringes 3. The electric push rod 15 is bolted to the left side of the base frame 1, and its telescopic rod extends vertically upward. The connecting plate 16 is bolted to the left side of the sliding frame 2. The end of the telescopic rod of the electric push rod 15 is fixedly connected to the connecting plate 16. Two scale plates 21 arranged front and back are bolted to the sliding frame 2. The lower part of the front scale plate 21 is bolted to the controller 23. The flow valve 7, the water pump 91 and the electric push rod 15 are all electrically connected to the controller 23.

[0022] like Figures 1-3 As shown, the material blocking assembly includes a support plate 11, an electric slide rail 12, an electric slider 13, and a material blocking frame 14. The support plate 11 is bolted to the right side of the sliding frame 2. The electric slide rail 12 is bolted to the support plate 11, and the electric slider 13 is slidably mounted on it. The material blocking frame 14 is bolted to the electric slider 13 and is located below the 480 syringes 3. The material blocking frame 14 has twelve baffles and twelve openings, which are alternately distributed. The twelve baffles are located below the twelve rows of syringes 3 and block the discharge ports at the bottom of the twelve rows of syringes 3. The top of the baffles is provided with a sealing gasket.

[0023] like Figure 1 and Figures 3-7As shown, the control assembly includes a support frame 17, an electric push rod 18, a pressure plate 19, a limit plate 20, and a pointer 22. The support frame 17 is bolted to the upper part of the sliding frame 2. The electric push rod 18 is bolted to the support frame 17, and its telescopic rod extends vertically downward. The electric push rod 18 is electrically connected to the controller 23. The pressure plate 19 is bolted to the end of the telescopic rod of the electric push rod 18. The pressure plate 19 is located above the 480 piston rods 5. Twelve limit plates 20 are fixedly connected to the lower part of the pressure plate 19 at equal intervals. Each limit plate 20 corresponds to a row of piston rods 5 and is fixedly connected to the upper end of a row of piston rods 5. A pointer 22 is bolted to each of the front and rear sides of the pressure plate 19. The pointer 22 forms a sliding fit with the corresponding scale plate 21. The scale plate 21 has two sets of scale lines. The pointer 22 has a tip at each end, which respectively indicates the two sets of scale lines.

[0024] In the initial state, the telescopic rod of electric push rod 15 is fully extended, the telescopic rod of electric push rod 28 is also fully extended, the piston block 51 is located at the lowest position inside the syringe 3, and the tip of pointer 22 points to the starting position of the scale line on the scale plate 21.

[0025] In use, the operator first injects an appropriate amount of sealing glue into the liquid storage tank 8 through the liquid inlet 81. Then, the operator starts the electric push rod 18 through the controller 23, controls its telescopic rod to retract upward, drives the pressure plate 19 to move upward, and the pressure plate 19 pulls all the piston rods 5 upward through the limit plate 20, so that the piston block 51 slides upward in the syringe 3. The operator observes the movement position of the pointer 22 on the scale plate 21 to accurately control the upward stroke of the piston block 51, thereby setting the required liquid storage space volume of the syringe 3. When the preset amount of glue is reached, the electric push rod 18 is immediately turned off.

[0026] Next, start the water pump 91 and open the flow valve 7 to connect the connecting pipe 6. The water pump 91 extracts the sealing glue from the storage tank 8 and distributes it to the twelve connecting pipes 6 through the diversion pipe 9. The glue first enters the leftmost syringe 3 in each row and then automatically flows into the remaining syringes 3 through the connecting pipe 4, so that all 480 syringes 3 are filled at the same time. When it is observed that the space under the piston block 51 in each syringe 3 is completely filled with glue, immediately turn off the water pump 91 and close the flow valve 7 to cut off the liquid supply path.

[0027] Then, start the electric push rod 15, control its telescopic rod to retract, and drive the sliding frame 2 to move downward along the base frame 1 until the bottom of the syringe 3 is close to the mouth of the firecracker tube to be sealed. Then, close the electric push rod 15, and then start the electric slide rail 12 to control the electric slider 13 to drive the baffle frame 14 to move backward, so that the opening on the baffle frame 14 is aligned with the discharge port of the 480 syringes 3, and the baffle is removed from the sealing position, thereby opening the discharge port of all syringes 3.

[0028] Next, start the electric push rod 18 again, control its telescopic rod to extend downward to the initial length, drive the pressure plate 19 downward, push all piston rods 5 and piston blocks 51 to press down synchronously through the limit plate 20, and push out the quantitative sealing glue in the syringe 3 evenly, inject it into the firecracker tube below, and complete the batch sealing glue injection.

[0029] After the glue is injected, start the electric push rod 15 again, control its telescopic rod to extend to the initial length, drive the sliding frame 2 to reset upward, so that the syringe 3 is away from the firecracker tube opening, and then control the electric slider 13 to drive the baffle frame 14 to move forward to the initial position, so that the baffle of the baffle frame 14 is re-aligned and fits against the discharge port of the syringe 3, and the sealing gasket at the top is used to effectively seal and prevent residual glue from dripping.

[0030] At this point, the automatic sealing operation of a batch of firecracker tubes is completed, the equipment returns to its initial state, and the next cycle of operation can begin.
