The existing equipment cannot realize full-process automation production, which becomes an important obstacle to the intelligent upgrading of fireworks manufacturing industry. UTILITY MODEL CONTENTS

[0004] The utility model aims at the above technical problems, and provides a kind of fireworks group pot machine binding device and fireworks group pot machine that can improve production efficiency and are convenient to maintain.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0006] The application discloses a fireworks group pot machine binding device, which comprises a rack and a rotating disc arranged on the rack, a plurality of positioning rollers are arranged on the rack and in rolling contact with the rotating disc, and the rotating disc rotates on the rack under the drive of a driving device, characterized in that a cutting device is arranged on one side of the rotating disc; the cutting device comprises a mounting plate arranged on the rack body and a rod body and a cutter arranged on the mounting plate; the rod body can rotate parallel to the plate surface of the mounting plate under the control of a first driving element, so as to rotate into or out of the working range of the rotating disc; the cutter can move towards or away from the rod body around a rotating shaft under the control of a second driving element, so as to cut the adhesive tape wound on the rod body, and the rotating shaft is arranged parallel to the plate surface of the mounting plate.

[0007] Therefore, the adhesive tape winding device realizes automatic binding of the fireworks cylinder through cooperation of the rod body and the cutter.

[0008] The device adopts a fixed number of winding modes, before the adhesive tape completes the predetermined number of winding, the first driving element controls the rod body to perform posture conversion: the rod body is switched from a vertical state to a horizontal state (or vice versa), at this time, the rod body end extends to above the fireworks cylinder. When the adhesive tape performs the last winding movement, the trajectory path is deviated due to the intervention of the rod body, and the adhesive tape body completes the final closed loop winding along the horizontal rod body surface.

[0009] After the winding action is terminated, the cutter is controlled by the second driving element to rotate to one side of the rod body and cut the adhesive tape wound on the rod body. After the cutter completes cutting, the cutter is automatically reset to a standby position, at this time, two independent adhesive tape sections are formed, i.e., a fixed section that has completed binding and a roll section that is reserved on the rotating disc. Since the cutter performs the cutting operation at one side of the rod body, the free end of the adhesive tape roll section is naturally adhered to the rod body.

[0010] When the next group of fireworks cylinders enters the working position, the first driving element reverses the rod body from the horizontal state to the vertical state, at this time, the free end of the adhesive tape adhered to the surface of the rod body is peeled off due to the change of the contact surface angle, the free end of the adhesive tape is attached to the surface of the new fireworks cylinder body, and the rotating disc continues to drive the adhesive tape roll to move into a new round of winding work.

[0034] The utility model will be explained in detail below with reference to the drawings and in combination with the embodiments. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only mean the same as the upper, lower, left and right directions of the drawings, and do not limit the structure.

[0035] As shown in the drawings, Figure 1 The fireworks group pot machine binding device of the embodiment comprises a frame 1 and a rotating disc 2 arranged on the frame 1 and used for mounting and driving the adhesive tape to rotate around the fireworks cylinder.

[0036] A cutting device 4 is arranged on the frame 1 at one side of the rotating disc 2. The cutting device 4 comprises a mounting plate 41 arranged on the frame 1 and a rod body 42 and a knife part 43 arranged on the mounting plate 41. The rod body 42 can rotate parallel to the plate surface of the mounting plate 41 under the control of a first driving part 5, so as to rotate into or out of the working range of the rotating disc 2. The knife part 43 can move close to or away from the rod body 42 around a rotating shaft 7 under the control of a second driving part 6, so as to cut the adhesive tape wound on the rod body 42. The rotating shaft 7 is arranged parallel to the plate surface of the mounting plate 41. The mounting plate 41 comprises a first plate part 411 and a second plate part 412 arranged side by side at one side of the first plate part 411. A connecting plate 413 is arranged between the first plate part 411 and the second plate part 412. The first driving part 5 and the second driving part 6 are both arranged on the second plate part 412, and the rod body 42 is rotationally connected with the first plate part 411. In the embodiment, the first driving part 5 and the second driving part 6 are both selected as servo motors.

[0037] As shown in the drawings, Figures 2-3As shown, the rod body 42 comprises a first part 421 arranged in parallel with the mounting plate 41 and a second part 422 arranged at the end of the first part 421 and arranged perpendicularly to the mounting plate 41. The first part 421 is rotatably connected to the mounting plate 41 by the second part 422 at one end close to the mounting plate 41 and extends away from the mounting plate 41 at the other end; the second part 422 penetrates the mounting plate 41 perpendicularly and is rotatably connected to the mounting plate 41, and the output end of the first driving member 5 is connected to the end of the second part 422.

[0038] Thus, the first driving member 5 drives the second part 422 of the rod body 42 to rotate, and simultaneously drives the first part 421 to rotate on the plate surface of the mounting plate 41 with the second part 422 as the rotation axis. In this embodiment, the first part 421 has two states, i.e. a vertical state and a horizontal state. In the vertical state, the first part 421 is in the non-working state, and in the horizontal state, the first part 421 is rotated to the upper side of the firework cylinder, which is the working state of the first part 421.

[0039] The first part 421 and the second part 422 are in L-shaped integral structure, or the end of the first part 421 and the end of the second part 422 are detachably connected by fasteners. In this embodiment, in order to facilitate maintenance and replacement, the first part 421 and the second part 422 are connected by the fastening mode of fasteners.

[0040] The cutter 43 comprises a transmission rod 431, one end of the transmission rod 431 is connected to the output end of the second driving member 6, and the other end is provided with a cutting knife 432; the second driving member 6 is arranged perpendicularly to the mounting plate 41, and a reversing mechanism 8 is connected to the power output end of the second driving member 6; the end of the transmission rod 431 is connected to the output end of the reversing mechanism 8 through the rotating shaft 7. The end of the transmission rod 431 away from the second driving member 6 is provided with a connecting piece 433, the connecting piece 433 is provided with the cutting knife 432 and a buffer piece 434, the buffer piece 434 is arranged on the side of the connecting piece 433 facing the cutting edge of the cutting knife 432, and the front end face of the buffer piece 434 exceeds the front end of the cutting edge of the cutting knife 432.

[0041] In order to make the structure of the cutting device 4 more compact and orderly, the second driving member 6 is arranged perpendicularly to the mounting plate 41, and thus the reversing mechanism 8 is needed to change the rotation direction of the rotating shaft 7 to the direction parallel to the mounting plate 41, and the rotating shaft 7 is arranged parallel to the mounting plate 41, so that the cutting knife 432 can move close to or away from the rod body 42 around the rotating shaft 7.

[0042] As Figure 4As shown, the cutter 43 of the embodiment is arranged on the left side of the rod body 42, and the winding direction of the adhesive tape needs to be counterclockwise to ensure that the free end of the adhesive tape roll can be attached to the rod body 42.

[0043] The working process of the cutting device 4 of the embodiment is as follows:

[0044] 1. The device adopts a fixed number of winding modes, for example, when the adhesive tape is wound to the fourth circle (total setting of 5 circles), the first driving member 5 controls the rod body to perform posture conversion;

[0045] 2. The first driving member 5 drives the second component 422 to rotate 90°, drives the first component 421 to switch from a vertical state to a horizontal state, and the end of the rod body 42 extends above the firework tube;

[0046] 3. The fifth circle of the adhesive tape is guided by the horizontal rod body during the winding process, and the winding path is transferred from the outer wall of the firework tube to the surface of the rod body, forming a closed loop;

[0047] 4. After completing the winding of the fifth circle, the turntable is paused, the output power of the second driving member 6 is transmitted to the transmission rod 431 by the reversing mechanism 8, the transmission rod 431 moves around the rotating shaft 7, the cutting knife 432 approaches the rod body in an arc trajectory, and the adhesive tape is cut off;

[0048] 5. After cutting, the second driving member 6 reverses to rotate, and the cutter returns to the initial position;

[0049] 6. The adhesive tape is divided into a fixed section of 5 circles remaining on the firework tube and a roll section remaining on the turntable, and the free end of the roll section is attached to the surface of the rod body;

[0050] 7. The next group of firework tubes is pushed into the working range of the bundling device, the first driving member 5 reverses to rotate, the rod body 42 switches from horizontal to vertical, the second component 422 rotates -90°, and the first component 421 is retracted to the side of the mounting plate 41;

[0051] 8. After the rod body is vertical, the free end of the adhesive tape is automatically separated from the rod body and attached to the starting position of the new firework tube due to the contact angle changing from 90° to 180° and the adhesion force decreasing, at this time, the turntable 2 continues to rotate and starts a new round of winding.

[0052] Based on the same inventive concept, the embodiment also provides a firework group pot machine, as shown in the accompanying drawings, which comprises a frame body 9, and the frame body 9 is sequentially provided with a feeding mechanism 10, a punching and inserting mechanism 11, a forming mechanism 12 and a discharging mechanism 13 along the material moving direction, and is characterized in that the discharging mechanism 13 comprises the firework group pot machine bundling device as described above arranged on the frame body 9. Figure 5

[0053] ​The fireworks group pot machine binding device of the embodiment realizes full-process automation of adhesive tape winding, cutting and free end transfer through the cooperation of the posture switching of the rod body (horizontal / vertical) and the timing cutting action of the cutter. After completing the closed-loop winding of the adhesive tape for the current firework cylinder, the horizontal state of the rod body can guide the free end of the adhesive tape to adhere to the surface of the rod body. When switched to the vertical state, the free end is automatically peeled off and transferred to the firework cylinder of the new work station, forming a seamless continuous operation cycle. The design breaks through the traditional manual intervention link, and the production efficiency is significantly improved.
