Description

Technical Field

[0001] The present invention relates to the technical field of firecracker production, and particularly to a firecracker tray transmission device for producing firecrackers. Background Art

[0002] In the traditional firecracker production process, a firecracker tray is a tray or container for accommodating and transporting firecrackers, or bundling multiple small firecrackers into a hexagon for convenient batch transportation and subsequent processing of firecrackers, and is usually processed by manual operation or a simple transmission system. In the prior art, the transmission of the firecracker tray is mainly for the processes of inserting fuses and adding medicine. When adding medicine, the firecracker tray needs to be lifted. When lifting, it will drive the movement of other firecracker trays on the conveyor belt, resulting in inaccurate movement positions of the firecrackers, and it is inconvenient to fix the firecracker tray during lifting. Therefore, a firecracker tray transmission device for producing firecrackers needs to be provided. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art that when adding medicine, the firecracker tray needs to be lifted, which will drive the movement of other firecracker trays on the conveyor belt, resulting in inaccurate movement positions of the firecrackers, and it is inconvenient to fix the firecracker tray during lifting, and thus propose a firecracker tray transmission device for producing firecrackers.

A sliding transmission roller sliding along the guiding chute is arranged in the middle of the base. A through shaft is arranged in the middle of the sliding transmission roller. The power output shaft of the servo motor is sleeved into the fixed transmission roller on the upper right side of the base. A conveyor belt is wound around the four fixed transmission rollers and the sliding transmission roller. A hydraulic rod is fixed on the lower right side of the base. A plurality of guiding columns are arranged at the bottom right side of the backing plate. A slidable lifting plate is arranged on the guiding columns. The telescopic end of the hydraulic rod is fixedly connected to the bottom of the lifting plate. Connecting frames are fixed on the front and rear sides of the lifting plate. Mounting brackets are symmetrically fixed on the front and rear of the right side of the base. A rotatable balance rod is arranged on the mounting brackets. Through holes are symmetrically opened on the left and right of the balance rod. One end of the connecting frame passes through the through hole on the right side of the balance rod. Both ends of the through shaft pass through the through holes on the left side of the balance rod.

[0005] Further preferably, connection brackets are symmetrically fixed to the front and rear on the right side of the upper part of the base. A slidable slider is provided on the connection bracket. Connecting columns are symmetrically fixed to the left and right at the front end of the slider. A slidable sliding seat is provided on the connecting column. An inclined hole is formed in the middle of the sliding seat. A slidable positioning seat is provided on the front side of the sliding seat. A first spring is sleeved on the positioning seat. A limiting block is fixed to the rear side of the sliding seat. One end of the connecting frame is fixed with a jacking frame, and one side of the jacking frame penetrates into the inclined hole.

[0006] Further preferably, guide groove frames are symmetrically fixed to the front and rear on the upper part of the base. A slidable lifting frame is provided on the guide groove frame. One side of the lifting frame is sleeved on the through shaft. A plurality of connecting discs are fixed to the middle of the lifting frame. Slidable positioning blocks are provided around the connecting disc. A second spring is sleeved on the positioning block.

[0007] Further preferably, a circular through hole is formed on the right side of the backing plate. The diameter of the circular through hole is the same as the diameter of the top disc of the jacking disc. The backing plate is in contact with the conveyor belt and supports the conveyor belt. The connecting frame is in an L shape. The balance rod is located at the midpoint between the connecting frame and the through shaft. The through holes symmetrically arranged on the left and right of the balance rod have the same shape.

[0008] Further preferably, the limiting block is in a "Π" shape. The limiting block is located on the top of the slider and is in contact with the top of the slider. One end of the first spring abuts against the sliding seat, and the other end of the first spring abuts against the positioning seat. The distance between adjacent connecting discs is the same. One side of the positioning block is in a wedge shape. One end of the second spring abuts against the connecting disc, and the other end of the positioning block abuts against the positioning block.

[0009] Further preferably, fixing frames are symmetrically fixed to the front and rear on the left side of the upper part of the base. A guide frame is fixedly connected to the fixing frame. The left part of the guide frame is obliquely arranged. A plurality of rotatable guide rollers are provided on the guide frame.

[0010] Further preferably, a connecting frame is fixed to the right side of the base. A cleaning brush is fixed to the right side of the connecting frame. The cleaning brush is in contact with the outer surface of the conveyor belt. A guide groove plate is fixed to the lower side of the connecting frame.

[0011] Further preferably, a plurality of raised anti-slip lines are provided at one end of the positioning seat.

[0012] Further preferably, a plurality of soft brushes are distributed in a staggered manner on the cleaning brush.

[0013] The beneficial effects of the present invention are as follows: The through shaft passes through the through hole on the left side of the balance rod. When the jacking disc and the connecting frame rise, the balance rod is driven to rotate. The rotation of the balance rod drives the through shaft to descend along the guiding chute, relaxing the conveyor belt. The connecting frame drives the jacking frame to rise along the inclined hole. The rising of the jacking frame will push the sliding seat, the positioning seat and the limiting block to slide along the connecting column, so that the positioning seat contacts the firecracker tray and compresses the first spring, positioning the firecracker tray at the processing position. When the disc on the top of the jacking disc coincides with the position of the circular through hole on the backing plate, at this time, the jacking disc contacts the inner surface of the conveyor belt, and the jacking frame rises to the vertex of the inclined hole, and the limiting block no longer contacts the top of the sliding block. The continuous rising of the jacking disc will drive the conveyor belt to slide and jack up the firecracker tray at the processing position. The continuous rising of the jacking frame will drive the sliding block and the components thereon to slide along the connecting bracket. After the positioning seat completes the positioning of the firecracker tray, it will rise together with the firecracker tray to be processed. During the jacking process, the firecracker tray is first positioned and then rises together with the firecracker tray, ensuring the stability during the transmission and jacking processes; When the balance rod rotates and drives the through shaft to descend, the lifting frame descends along the guiding groove frame. The lifting frame drives the connecting disc and the positioning block thereon to descend together. One side of the positioning block is wedge-shaped. When it contacts the firecracker tray during the descending process, the positioning block slides along the connecting disc and compresses the second spring. When the firecracker tray at the processing position rises, it contacts the four inclined surfaces of the unprocessed firecracker tray, preventing the other unprocessed firecracker trays from sliding during the medicine adding process, which may affect the continuous processing of the firecrackers.

Detailed implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] Refer to Figures 1 to 8 , a firecracker tray transmission device for producing firecrackers, including a base 1. A guiding chute 101 is opened on the lower side of the middle part of the base 1. A backing plate 102 is fixed between the front and rear sides of the top of the base 1. A servo motor 2 is fixed on the right side of the upper part of the base 1. Four rotatable fixed transmission rollers 3 are symmetrically distributed on the upper and lower sides of the base 1. A sliding transmission roller 4 that slides along the guiding chute 101 is arranged in the middle of the base 1. A through shaft 401 is arranged in the middle of the sliding transmission roller 4. The power output shaft of the servo motor 2 is sleeved into the fixed transmission roller 3 on the right side of the upper part of the base 1. A transmission belt 5 is wound around the four fixed transmission rollers 3 and the sliding transmission roller 4. A hydraulic rod 6 is fixed on the right side of the lower part of the base 1. A plurality of guiding columns 7 are arranged at the bottom right side of the backing plate 102. A slidable lifting disc 8 is arranged on the guiding columns 7. The telescopic end of the hydraulic rod 6 is fixedly connected to the bottom of the lifting disc 8. It is characterized in that: connecting frames 9 are fixed on the front and rear sides of the lifting disc 8. Mounting brackets 10 are symmetrically fixed on the front and rear of the right side of the base 1. A rotatable balance rod 11 is arranged on the mounting brackets 10. Through holes 1101 are symmetrically opened on the left and right sides of the balance rod 11. One end of the connecting frame 9 penetrates through the through hole 1101 on the right side of the balance rod 11. Both ends of the through shaft 401 penetrate through the through hole 1101 on the left side of the balance rod 11.

[0018] Preferably, connecting supports 12 are symmetrically fixed on the front and rear of the right side of the upper part of the base 1. A slidable sliding block 13 is arranged on the connecting supports 12. Connecting columns 1301 are symmetrically fixed on the front end of the sliding block 13. A slidable sliding seat 14 is arranged on the connecting columns 1301. An inclined hole 1401 is opened in the middle of the sliding seat 14. A slidable positioning seat 15 is arranged on the front side of the sliding seat 14. A first spring 16 is sleeved on the positioning seat 15. A limiting block 17 is fixed on the rear side of the sliding seat 14. One end of the connecting frame 9 is fixed with a lifting frame 18. One side of the lifting frame 18 penetrates into the inclined hole 1401; During specific implementation, the connecting frame 9 drives the jacking frame 18 to rise along the inclined hole 1401. As the jacking frame 18 rises, it will push the sliding seat 14, the positioning seat 15 and the limiting block 17 to slide along the connecting column 1301, so that the positioning seat 15 contacts the firecracker tray and positions the firecracker tray. When the jacking frame 18 rises to the vertex of the inclined hole 1401 and the limiting block 17 no longer contacts the top of the sliding block 13, when the jacking frame 18 continues to rise, it will drive the sliding block 13 and the components thereon to slide along the connecting bracket 12, and the positioning seat 15 will rise together when positioning the firecracker tray.

[0019] Preferably, guide groove frames 19 are symmetrically fixed to the front and rear of the upper part of the base 1. A slidable lifting frame 20 is provided on the guide groove frames 19. One side of the lifting frame 20 is sleeved on the through shaft 401. A plurality of connecting plates 21 are fixed in the middle of the lifting frame 20. Slidable positioning blocks 22 are provided around the connecting plates 21. A second spring 23 is sleeved on the positioning blocks 22; During specific implementation, when the balance rod 11 rotates to drive the through shaft 401 to descend, the lifting frame 20 descends along the guide groove frame 19. The lifting frame 20 drives the connecting plate 21 and the positioning blocks 22 thereon to descend together. During the descending process, when contacting the firecracker trays that are not in the processing position, since one side of the positioning block 22 is wedge-shaped, the positioning block 22 slides along the connecting plate 21 and compresses the second spring 23. By contacting the four inclined surfaces of the firecracker tray, it is prevented that the other firecracker trays that are not in the dosing position slide during the dosing process of the firecracker tray.

[0020] Preferably, a circular through hole is opened on the right side of the backing plate 102. The diameter of the circular through hole is the same as the diameter of the top disc of the jacking disc 8. The backing plate 102 contacts the conveyor belt 5 and supports the conveyor belt 5. The connecting frame 9 is in an L shape. The balance rod 11 is located at the midpoint between the connecting frame 9 and the through shaft 401. The through holes 1101 symmetrically arranged on the left and right of the balance rod 11 have the same shape; During specific implementation, when the connecting frame 9 rises, it drives the balance rod 11 to rotate, so that the sliding transmission roller 4 and the through shaft 401 descend along the guide chute 101, relaxing the conveyor belt 5. When the jacking disc 8 rises to the circular through hole on the backing plate 102 and contacts the conveyor belt 5, the jacking disc 8 continues to rise and will drive the conveyor belt 5 to slide and jack up the firecracker tray in the processing position. Preferably, the limiting block 17 is in a "Π" shape. The limiting block 17 is located on the top of the sliding block 13 and contacts the top of the sliding block 13. One end of the first spring 16 abuts against the sliding seat 14, and the other end of the first spring 16 abuts against the positioning seat 15. The distance between adjacent connecting plates 21 is the same. One side of the positioning block 22 is wedge-shaped. One end of the second spring 23 abuts against the connecting plate 21, and the other end of the positioning block 22 abuts against the positioning block 22; During specific implementation, the limiting block 17 is in contact with the top of the sliding block 13 to position the sliding block 13 and prevent the sliding block 13 from sliding along the connecting bracket 12 when the jacking frame 18 rises along the inclined hole 1401.

[0021] Preferably, fixing frames 24 are symmetrically fixed to the front and rear on the left side of the upper part of the base 1. A guiding frame 25 is fixedly connected to the fixing frames 24. The left part of the guiding frame 25 is inclined, and a plurality of rotatable guiding rollers 26 are arranged on the guiding frame 25. During specific implementation, when the firecracker tray moves along with the conveyor belt 5 and contacts the inclined surface on one side of the guiding frame 25, the firecracker tray will rotate, avoiding skew of the firecracker tray and maintaining the consistency of the feeding position. A plurality of guiding rollers 26 on the guiding frame 25 can position the firecracker tray, and when the guiding rollers 26 contact the firecracker tray, the firecracker tray can move more smoothly along with the conveyor belt 5.

[0022] Preferably, a connecting frame 27 is fixed to the right side of the base 1. A cleaning brush 28 is fixed to the right side of the connecting frame 27. The cleaning brush 28 is in contact with the outer surface of the conveyor belt 5. A guiding groove plate 29 is fixed to the lower side of the connecting frame 27. During specific implementation, when the conveyor belt 5 moves, the cleaning brush 28 is constantly in contact with the outer surface of the conveyor belt 5 to clean the dust falling on the conveyor belt 5. The cleaned dust flows out along the guiding groove plate 29 and is then collected.

[0023] Wherein, one end of the positioning seat 15 is provided with a plurality of raised anti-slip lines.

[0024] Wherein, a plurality of soft brushes are distributed in a staggered manner on the cleaning brush 28.

[0025] When the present invention is in use, the servo motor 2 is started to drive the fixed conveyor roller 3 and the sliding conveyor roller 4 to rotate, so that the conveyor belt 5 moves. The firecracker tray is placed on the conveyor belt 5. When the conveyor belt 5 moves, the cleaning brush 28 is constantly in contact with the outer surface of the conveyor belt 5 to clean the dust falling on the conveyor belt 5. The cleaned dust flows out along the guiding groove plate 29 and is then collected. The firecracker tray moves along with the conveyor belt 5. When it contacts the inclined surface on one side of the guiding frame 25, the firecracker tray will rotate, avoiding skew of the firecracker tray and maintaining the consistency of the feeding position. When the firecracker tray moves to the processing position, the hydraulic rod 6 is activated. The telescopic end of the hydraulic rod 6 drives the lifting tray 8 and the connecting frame 9 to slide along the guiding column 7. When the connecting frame 9 rises, it drives the balance rod 11 to rotate, causing the sliding transmission roller 4 and the through shaft 401 to descend along the guiding chute 101, relaxing the conveyor belt 5. The connecting frame 9 drives the lifting frame 18 to rise along the inclined hole 1401. As the lifting frame 18 rises, it pushes the sliding seat 14, the positioning seat 15 and the limiting block 17 to slide along the connecting column 1301, so that the positioning seat 15 contacts the firecracker tray and positions the firecracker tray. When the lifting tray 8 rises to the circular through hole on the cushion plate 102 and contacts the conveyor belt 5, and the lifting frame 18 rises to the vertex of the inclined hole 1401 and the limiting block 17 no longer contacts the top of the sliding block 13, the lifting tray 8 continues to rise, driving the conveyor belt 5 to slide and lifting the firecracker tray at the processing position. The lifting frame 18 continues to rise, driving the sliding block 13 and the components thereon to slide along the connecting bracket 12, and the positioning seat 15 rises together when positioning the firecracker tray; When the balance rod 11 rotates to drive the through shaft 401 to descend, the lifting frame 20 descends along the guiding groove frame 19. The lifting frame 20 drives the connecting plate 21 and the positioning block 22 thereon to descend together. During the descending process, when contacting the firecracker tray not in the processing position, since one side of the positioning block 22 is wedge-shaped, the positioning block 22 slides along the connecting plate 21 and compresses the second spring 23. By contacting the four inclined surfaces of the firecracker tray, it is prevented that the other firecracker trays not in the medicine adding position slide during the medicine adding process; The lifting tray 8 stops after lifting the firecracker tray to the medicine adding station. After the medicine adding is completed, the hydraulic rod 6 resets, and the servo motor 2 is started again to move the next firecracker tray to the processing position.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
