Description

Technical Field

[0001] This utility model relates to the field of firecracker production, and in particular to a firecracker production reel device. Background Technology

[0002] During the production of firecrackers, a stringing machine is usually used to string together several individual firecrackers into a long firecracker strip. After the firecracker strip is formed, it needs to be wound into a disc. Then, the cut-off end of the firecracker is glued to the inner layer of the firecracker to form a firecracker disc for easy storage and transportation.

[0003] The existing firecracker reeling machine requires workers to cut the firecrackers with scissors after reeling, and then apply glue to the cut end. This is quite troublesome and inconvenient to apply glue at the same time as cutting the firecrackers, resulting in low work efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of existing firecracker reel machines, which are not convenient for applying glue while cutting firecrackers, resulting in low work efficiency, this utility model provides a firecracker production reel device that can facilitate the application of glue while cutting firecrackers, thereby improving work efficiency.

[0005] The technical solution of this utility model is as follows: A firecracker production reel device, comprising a base frame;

[0006] A vertical plate installed at the top of the base frame;

[0007] Three tensioning rollers are rotatably connected to the upper part of the vertical plate;

[0008] Two guide rollers are rotatably connected to the vertical plate;

[0009] A winding mechanism is installed on the vertical plate;

[0010] Cut-off mechanism installed on the vertical plate.

[0011] Optionally, the winding mechanism includes a servo motor fixed to a vertical plate, a turntable rotatably connected to the vertical plate, the output shaft of the servo motor fixed to the turntable, two clamping plates fixed to the turntable, a sliding frame slidably connected to the vertical plate, a spring disposed between the vertical plate and the sliding frame, and a pressure wheel rotatably connected to the lower part of the sliding frame.

[0012] Optionally, the cutting mechanism includes an electric push rod disposed on the vertical plate, a sliding plate slidably connected to the vertical plate, a telescopic rod of the electric push rod fixedly connected to the sliding plate, a blade fixedly connected to the sliding plate, and a bonding plate fixedly connected to the vertical plate, the bonding plate having a cutting groove.

[0013] Optionally, it also includes an adhesive application mechanism disposed on the vertical plate and the sliding plate. The adhesive application mechanism includes an adhesive box fixed to the vertical plate, an adhesive applicator rotatably connected to the vertical plate with the lower part of the applicator located inside the adhesive box, an overrunning clutch fixed to the applicator, a transmission frame slidably connected to the vertical plate with the lower part of the transmission frame fixed to the sliding plate, a rack fixed to one side of the transmission frame, and a gear fixed to the outer ring of the overrunning clutch, the gear meshing with the rack.

[0014] Optionally, it also includes several limiting brackets fixed to the vertical plate.

[0015] The beneficial effects of this utility model are: 1. The sliding plate moves to drive the blade and the transmission frame to move. The transmission frame moves to drive the rack to move. The rack moves to drive the gear to rotate. The gear drives the glue applicator to rotate upward through the overrunning clutch. The lower part of the glue applicator applies glue to the left side of the firecracker near the blade groove of the bonding plate. This makes it easy to apply glue while cutting the firecracker, thus improving work efficiency.

[0016] 2. By using a limit frame to limit the movement of the firecrackers, it is possible to prevent the firecrackers from shifting or coming off the tension rollers and improve the flatness of the firecracker reel. Attached Figure Description

Detailed Implementation

[0023] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0024] Example 1: A firecracker production reel device, such as Figures 1-5 As shown, it includes, base frame 1;

[0025] Vertical plate 2 welded to the top of base frame 1;

[0026] Three tensioning rollers 3 are connected to the upper part of the vertical plate 2 via bearings;

[0027] Two guide rollers 4 are connected to the vertical plate 2 by bearings;

[0028] A winding mechanism is provided on the vertical plate 2, which is used to wind firecrackers into a disc;

[0029] A cutting mechanism is provided on the vertical plate 2, which is used to cut the firecracker.

[0030] The winding mechanism includes a servo motor 51 fixed to the vertical plate 2, a turntable 52 rotatably connected to the vertical plate 2, the output shaft of the servo motor 51 being fixed to the turntable 52, two clamping plates 53 fixed to the turntable 52, the two clamping plates 53 being symmetrically arranged, the servo motor 51 driving the two clamping plates 53 to rotate through the turntable 52, thereby driving the firecracker to be wound into a disc, a sliding frame 54 slidably connected to the vertical plate 2, a spring 55 disposed between the vertical plate 2 and the sliding frame 54, and a pressure wheel 56 rotatably connected to the lower part of the sliding frame 54. The pressure wheel 56 is used to press the firecracker during winding, making the wound firecracker disc more compact.

[0031] The cutting mechanism includes an electric push rod 61 mounted on the vertical plate 2, a sliding plate 62 slidably connected to the vertical plate 2, a telescopic rod of the electric push rod 61 fixedly connected to the sliding plate 62, a blade 63 fixedly connected to the sliding plate 62, and an adhesive plate 64 fixedly connected to the vertical plate 2. The adhesive plate 64 has a cutting groove. The electric push rod 61 drives the blade 63 to move through the sliding plate 62, thereby cutting the firecracker.

[0032] It also includes a glue-applying mechanism disposed on the vertical plate 2 and the sliding plate 62. The glue-applying mechanism is used to apply glue to the firecracker before it is cut off. The glue-applying mechanism includes a glue box 71 fixed to the vertical plate 2, a glue applicator 72 rotatably connected to the vertical plate 2, the lower part of the glue applicator 72 being located inside the glue box 71, an overrunning clutch 73 fixed to the glue applicator 72, a transmission frame 74 slidably connected to the vertical plate 2, the lower part of the transmission frame 74 being fixed to the sliding plate 62, a rack 75 fixed to one side of the transmission frame 74, and a gear 76 fixed to the outer ring of the overrunning clutch 73. The gear 76 meshes with the rack 75. The sliding plate 62 drives the rack 75 to move through the transmission frame 74, and then drives the glue applicator 72 to apply glue to the cut-off end of the firecracker through the gear 76 and the overrunning clutch 73.

[0033] Initially, the glue container 71 contains an appropriate amount of glue. The lower part of the glue applicator 72 is located inside the glue container 71 and below the glue level. After starting work, the operator places the firecrackers according to the instructions. Figure 1 The firecrackers are passed sequentially between the three tensioning rollers 3 and the two guide rollers 4, and one end of the firecracker is inserted between the two clamping plates 53. Then, the operator starts the servo motor 51 to rotate counterclockwise (as per the instruction manual). Figure 1 From the perspective of [the viewpoint], the output shaft of the servo motor 51 rotates, driving the turntable 52 to rotate. The rotation of the turntable 52 drives the two clamping plates 53 to rotate, and the rotation of the two clamping plates 53 drives the firecracker to gradually wind into a disc shape. As the diameter of the firecracker disc increases, the section of firecracker between the firecracker disc and the guide roller 4 will shift upward around one of the guide rollers 4 near the electric push rod 61 and contact the pressure wheel 56. The spring 55 is compressed and continuously applies pressure to the firecracker disc through the sliding frame 54 and the pressure wheel 56, making the firecracker disc wind more tightly. When the firecracker disc is wound to the specified size, the distance between the firecracker disc and the guide roller 4... This section of firecracker will adhere to the lower part of the bonding plate 64. At this time, the operator stops the servo motor 51 and controls the extension rod of the electric push rod 61 to retract. The extension rod of the electric push rod 61 drives the sliding plate 62 to move. The movement of the sliding plate 62 drives the blade 63 and the transmission frame 74 to move. The movement of the transmission frame 74 drives the rack 75 to move. The movement of the rack 75 drives the gear 76 to rotate. The gear 76 drives the glue applicator 72 to rotate upward through the overrunning clutch 73. The lower part of the glue applicator 72 applies glue to the left side of the firecracker near the blade groove of the bonding plate 64. Through the above operation, it is easy to cut the firecracker. Simultaneously, glue is applied to improve work efficiency. The rack 75 continues to move and disengages from the gear 76. Under gravity, the glue applicator 72 rotates downwards to reset. This downward rotation of the glue applicator 72 drives the overrunning clutch 73 to rotate downwards as well. The blade 63 continues to move, contacting and cutting the firecracker. After the firecracker is cut, the worker controls the servo motor 51 to continue rotating a short distance, allowing the pressure roller 56 to apply pressure to the glued area of ​​the firecracker, causing the cut end to adhere to the firecracker disc. The worker then removes the coiled firecracker disc, and the spring 55 returns, driving the sliding... The moving frame 54 and the pressure wheel 56 move downwards to reset. Then, the operator controls the extension rod of the electric push rod 61 to extend and reset. The extension rod of the electric push rod 61 drives the sliding plate 62 to move in the opposite direction. The reverse movement of the sliding plate 62 drives the blade 63 and the transmission frame 74 to move in the opposite direction. The reverse movement of the transmission frame 74 drives the rack 75 to move in the opposite direction. The reverse movement of the rack 75 engages with the gear 76 and drives the gear 76 to rotate in the opposite direction. Under the action of the overrunning clutch 73, the glue applicator 72 will not rotate. Finally, the operator re-inserts the cut-off end of the firecracker into the two clamps 53 to facilitate the next operation.

[0034] Example 2: Based on Example 1, such as Figures 1-2As shown, it also includes several limiting frames 8 welded to the vertical plate 2.

[0035] When inserting firecrackers, the staff will pass the firecrackers through several limiting frames 8 in sequence. The limiting frames 8 can limit the firecrackers as they move, preventing them from shifting or coming off the tension rollers 3 and guide rollers 4, thus improving the flatness of the firecracker reel.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
