Description

Technical Field

[0001] This utility model belongs to the field of fireworks manufacturing technology, and in particular relates to a tape tension adjustment mechanism, a firework assembly machine binding device, and a firework assembly machine. Background Technology

[0002] In the production of modular fireworks, after the fireworks tubes are glued together into a block, the block needs to be bound together with tape.

[0003] Existing tape bundling devices include a rotatable circular frame with a roll of tape mounted on it. The tape roll moves in a circular motion driven by the frame, wrapping the free end of the tape around the block and securing it firmly. An example is the tape winding mechanism disclosed in Chinese invention patent CN106362744B, entitled "Tape Winding Device and Automatic Fireworks Assembly Machine." However, in actual production, due to excessive deviation between the block's center point and the circular frame, or excessive tape extension, the tape easily loosens and wrinkles, affecting the bundling quality of the block and ultimately impacting the production efficiency and product quality of assembled fireworks. Utility Model Content

[0004] This utility model solves the problems existing in the prior art by providing a tape tension adjustment mechanism, a firework assembly machine binding device, and a firework assembly machine.

[0005] To achieve the above objectives, one of the technical solutions of this utility model is: a tape tension adjustment mechanism, including a frame and a winding assembly mounted on the frame. The winding assembly includes a tape reel. The tape reel is rotated by the winding assembly's circumferential movement to release the tape and wrap it around the workpiece. A rotating component is provided on the mounting shaft of the tape reel. The rotating component drives the mounting shaft to rotate in the same direction as the rotation of the winding assembly, but opposite to the direction of tape release.

[0006] Furthermore, the winding assembly also includes a turntable, which is rotatably mounted on the frame, and the mounting shaft is perpendicularly mounted on the rotating surface of the turntable, and the turntable drives the tape reel to rotate.

[0007] Furthermore, the rotating assembly includes a pinion gear and a fixed gear, the pinion gear is fixed to one end of the mounting shaft, the pinion gear meshes with the fixed gear, and the fixed gear is fixed to the frame.

[0008] Furthermore, a drive assembly is provided on the frame, the drive assembly including a motor, a transmission gear and several guide wheels, the inner ring of the turntable is set on the guide wheels, and the outer wall of the turntable is fixed with external teeth, which mesh with the transmission gear. The transmission gear is mounted on the output shaft of the motor, and the motor drives the transmission gear to rotate, thereby realizing the rotation of the turntable. The turntable and the guide wheels fixed on the frame form a rolling connection.

[0009] Furthermore, the turntable is fixedly connected to one end of the mounting shaft via a bearing. The turntable drives the tape reel on the mounting shaft to rotate. The tape reel is mounted on the other end of the mounting shaft. A pinion is fixed to the other end of the mounting shaft and meshes with the fixed gear. The tape reel releases the tape by covering the workpiece and rotating. The pinion and the turntable drive the mounting shaft to rotate in the opposite direction to the tape release position. The opposing force applied to the mounting shaft can effectively adjust the tension of the tape on the tape reel at any time.

[0010] Furthermore, the fixed gear disk is arranged parallel to the turntable.

[0011] Furthermore, the tape reels are at least two arranged in parallel, and a spring is provided between two adjacent tape reels. This helps to increase the friction between the tape reels and the mounting shaft when the tape is released, thereby adjusting the tension of the tape and keeping the tape position consistent.

[0012] The tape tension adjustment mechanism according to the embodiment of this utility model has at least the following beneficial effects:

[0013] Based on existing technology, a small gear disk is designed and installed on the mounting shaft of the tape reel, which meshes with a fixed large gear disk to limit the position of the tape reel. During rotation, the tape does not wobble or loosen, maintaining a certain tension and directionality of the tape. This effectively overcomes the problems of tape loosening and wrinkling that exist in existing technologies.

[0014] The second technical solution of this utility model is to provide a binding device for a fireworks assembly machine, including the tape tension adjustment mechanism mentioned above.

[0015] Furthermore, the firework assembly machine binding device also includes a cutting component, which is mounted on the frame and used to cut the tape on the tape reel.

[0016] Furthermore, the cutting assembly includes a mounting plate, a rod, and a blade. The mounting plate is fixed to the frame, and the rod and blade are mounted on the mounting plate. The rod can rotate parallel to the surface of the mounting plate under the control of a first drive unit, thereby entering or leaving the working range of the turntable. The blade can move towards or away from the rod around a rotating axis under the control of a second drive unit to cut the tape wrapped around the rod. The rotating axis is arranged parallel to the surface of the mounting plate.

[0017] The third technical solution of this utility model is: to provide a fireworks assembly machine, which is provided with a feeding device, a punching and inserting device, a forming device and a discharging device arranged in sequence along the material moving direction, wherein the discharging mechanism includes the fireworks assembly machine binding device as described above.

[0018] The beneficial effects of this utility model are:

[0019] This invention addresses the problem of tape loosening and wrinkling in existing tape binding devices by incorporating a tape tension adjustment mechanism. This mechanism applies a force in the opposite direction to the tape release, effectively solving the issues of tape loosening and wrinkling. The tape wrapping is well-fitted, and the mechanism is simple in structure, stable in function, and eliminates the need for manual intervention. It effectively achieves continuous production, improves product packaging quality, and enhances production efficiency. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] See Figure 1-3 A tape tension adjustment mechanism includes a frame 1, a turntable 2, and a mounting shaft 3. The turntable is rotatably mounted on the frame, and the mounting shaft is mounted on the turntable and perpendicular to the rotation surface of the turntable. One end of the mounting shaft is provided with a tape reel 31 for releasing tape 32, and the other end of the mounting shaft is provided with a small gear disc 4. The small gear meshes with a fixed gear disc 5, which is fixed to the frame.

[0037] In this embodiment, the turntable is a turntable 22 mounted on the guide wheel 21. The turntable meshes with the transmission gear 23, which is mounted on the output shaft of the motor 24. The motor drives the transmission gear to rotate, thereby realizing the rotation of the turntable. There can be multiple guide wheels mounted on the frame. The guide wheels are in rolling contact with the turntable. Existing technology can be used here, and the specific technical solution will not be described in detail here.

[0038] In this embodiment, the other end of the mounting shaft is connected to the turntable via bearing 33. A small gear is fixed on one side of the turntable on the mounting shaft, and the small gear meshes with and connects to the fixed gear.

[0039] In this embodiment, the fixed gear disk is arranged parallel to the turntable.

[0040] See Figure 4 In this embodiment, the tape reels are two parallel and symmetrically sleeved on one end of the mounting shaft, including tape 32 and bracket 312. A flange 311 is fixed on the mounting shaft. The flange is used to stop the tape. A spring 34 is set between two adjacent brackets. The spring is sleeved on the mounting shaft and its two ends are fixed to the brackets respectively. A locking washer 313 is set at the end of the mounting shaft away from the pinion disc. It cooperates with the flange to limit the tape and fix the bracket.

[0041] See Figure 5 , Figure 6 The working principle of this embodiment is as follows:

[0042] The motor 24 rotates, driving the transmission gear 23 to rotate, which in turn drives the turntable 22 to rotate. The mounting shaft 3 of the tape reel 31 passes vertically through the turntable, and the turntable is fixedly connected to the mounting shaft through bearings. A small gear 4 is mounted at the end of the mounting shaft and meshes with a fixed gear 5 mounted parallel to one side of the turntable. The rotation direction of the mounting shaft driven by the small gear 4 is the same as the rotation direction of the turntable, while the release direction of the tape on the bracket is opposite to the rotation direction of the mounting shaft and the rotation direction of the turntable. In this embodiment, the turntable and the mounting shaft rotate clockwise. The friction force of the bracket and other components on the mounting shaft drives the tape on the mounting shaft to rotate clockwise. The tape releases by rotating counterclockwise to bind the workpiece 6. When the tape loosens, the force of the rotation direction of the mounting shaft driven by the small gear 4 adjusts the tension of the tape reel, thereby always maintaining the tension of the tape. The spring 34 between the brackets can appropriately increase the friction of the tape reel, thereby effectively adjusting the tension of the tape and preventing the tape from becoming too tight.

[0043] Example 2

[0044] See Figure 7 , Figure 8 A firework assembly machine binding device includes the tape tension adjustment mechanism described above.

[0045] The firework assembly bundle binding device described in this embodiment also includes a cutting component 7, which is mounted on the frame and used to cut the tape on the tape reel.

[0046] The cutting assembly described in this embodiment includes a mounting plate 71, a rod 72, and a blade 73. The mounting plate is fixed to the frame and located on one side of the turntable. The rod and blade are mounted on the mounting plate. The rod can rotate parallel to the surface of the mounting plate under the control of the first drive member 74, thereby rotating into or out of the working range of the turntable. The blade can move towards or away from the rod around a rotating axis under the control of the second drive member 75 to cut the tape wrapped around the rod. The rotating axis is set parallel to the surface of the mounting plate.

[0047] Both the first and second driving components can be servo motors, and the cutting components can also adopt existing technologies. The specific technical solutions will not be elaborated here.

The discharging device 15 includes the firework assembly machine binding device as described above, which is arranged on the frame 11.

[0050] This invention effectively solves the problems of easy loosening and wrinkling of the tape in existing tape binding devices by setting a tape tension adjustment mechanism. The tape wrapping has good adhesion. The mechanism has a simple structure, stable function, saves manual intervention time, effectively realizes continuous production, and improves product packaging quality and production efficiency.
