Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, in particular to a fireworks paper tube cutting device. Background Art

[0002] Fireworks are pyrotechnic entertainment products that use pyrotechnic powder to produce sound, light, and color effects through combustion or explosion for viewing. The production process of the outer layer of fireworks, the paper tube, is relatively complex. First, the glue required for rolling the paper tube is supplied by a glue spraying method, and then the paper roll is mechanically formed into the firework paper tube. To speed up production and save labor, the firework paper tube is usually rolled into a long length and then cut into appropriate lengths according to actual needs.

[0003] The currently available firework paper tube cutting device usually first bundles the firework paper tubes vertically into a regular hexagonal bundle, then clamps and fixes the firework paper tubes, and then uses a cutting device to cut the firework paper tubes as needed. However, debris and dust are generated during the cutting process of the firework paper tubes. The existing device is difficult to clean the generated debris and dust, which is likely to affect the working environment and equipment.

[0004] Therefore, in order to solve the above problems, a firework paper tube cutting device has been developed that can clean up the debris and dust generated during the cutting process to avoid affecting the working environment and equipment. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices that are difficult to clean the debris and dust generated during the cutting process and easily affect the working environment and equipment, the utility model provides a firework paper tube cutting device that can clean the debris and dust generated during the cutting process to avoid affecting the working environment and equipment.

[0006] The technical solution is: a firework paper tube cutting device, including a frame, a support frame, a passive telescopic rod, a motor, a rotating disk, a transmission component, a connecting rod, an active lifting rod, a wire saw, a locking piece and a mobile control mechanism. The upper side of the middle and rear part of the frame is connected to the support frame, the upper part of the support frame is connected to the passive telescopic rod, the lower side of the frame is connected to the motor, the lower part of the frame is rotatably connected to the rotating disk, the transmission component is connected between the rotating disk and the motor output shaft, the rotating disk is rotatably connected to the connecting rod, the connecting rod is rotatably connected to the active lifting rod, the active lifting rod is slidably connected to the frame, and the telescopic end of the active lifting rod and the passive telescopic rod are connected. A wire saw is connected to the frame, and a locking piece is provided on the telescopic end of the passive telescopic rod. The firecracker paper tubes vertically bundled into a regular hexagon are placed on the frame. The rotation of the motor output shaft drives the rotating disk to rotate through the transmission assembly. The rotation of the rotating disk drives the active lifting rod to slide up and down through the connecting rod, thereby cooperating with the passive telescopic rod to make the wire saw move back and forth up and down, so that the firecracker paper tube can be cut by the wire saw during the movement. The locking piece is used to fix the wire saw. When the wire saw needs to be replaced, the locking piece can be separated from the wire saw and the telescopic end of the passive telescopic rod. A movement control mechanism is provided on the frame.

[0007] Furthermore, the mobile control mechanism includes a rodless cylinder, a sliding table, a pneumatic telescopic rod, a clamp and a nozzle. The upper sides of the front and rear parts of the frame are connected with rodless cylinders. The rodless cylinders are slidably connected to the sliding tables. Both ends of the sliding tables are connected to pneumatic telescopic rods. Clamps are connected between the telescopic ends of two adjacent pneumatic telescopic rods. The clamps are connected to nozzles. The nozzles are connected to external dust suction equipment so that the firework paper tube is located between the clamps. The clamps are driven to move toward the side close to each other by the telescopic ends of the pneumatic telescopic rods to clamp the firework paper tube. The sliding table is then controlled to move to the right by the rodless cylinder, thereby driving the firework paper tube to move to the right. During the cutting process, the debris and dust generated are sucked by negative pressure through the external dust suction equipment.

[0008] Furthermore, the movement control mechanism also includes an isolation net, and adjacent sides of the clamp are connected to the isolation net.

[0009] Furthermore, it also includes a discharging mechanism, which includes a belt conveyor, a connecting frame, a guide frame and an elastic part. A belt conveyor is provided on the right side of the frame, and the front and rear sides of the right side of the belt conveyor are connected to connecting frames, and the connecting frames are slidably connected to guide frames. The left and right parts of the guide frames are connected to the adjacent connecting frames with elastic parts. After the cutting of the fireworks paper tube is completed, the sliding platform is controlled by the rodless cylinder to move to the right to the limit, and the fireworks paper tube is located on the belt conveyor. The telescopic end of the pneumatic telescopic rod drives the clamp to move to the side away from each other and reset. At this time, under the guiding action of the guide frame, the cut fireworks paper tube is discharged by the belt conveyor, and the fireworks paper tube is limited by the guide frame during the discharging process to avoid tipping over during the discharging process.

[0010] Furthermore, the left portion of the guide frame is tilted to facilitate guiding the cut firecracker paper tubes.

[0011] Furthermore, the elastic member is a spring.

[0012] Compared with the existing technology, the utility model has the following advantages: 1. The utility model isolates part of the space between the clamp and the firecracker paper tube through the isolation net. During the cutting process, the debris and dust generated are sucked by the external dust suction equipment under negative pressure, which can clean the debris and dust generated during the cutting process and avoid affecting the working environment and equipment.

[0013] 2. The utility model uses a rodless cylinder to control the sliding platform to transport the firecracker paper tubes to the belt conveyor. Under the guidance of the guide frame, the cut firecracker paper tubes are discharged through the belt conveyor, and the firecracker paper tubes are limited by the guide frame during the discharging process, which can prevent the firecracker paper tubes from tipping over during the discharging process.
