DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 5 As shown: An automatic plug-in device for connecting wires for fireworks production, comprising a frame 1 and a plug-in mechanism 2 arranged beside the frame 1, a turntable 11 is provided on the frame 1, the axis of the turntable 11 is arranged in a horizontal state, and a plurality of semicircular assembly grooves 111 equidistantly surrounding the axis of the turntable 11 are provided on the turntable 11, the plug-in mechanism 2 comprises a housing 21, a mounting bar 22, a first clamping mechanism 23 for clamping the sticker on the firework tube 3, and a second clamping mechanism 24 for clamping the wire 31; the housing 21 is located beside the turntable 11; the mounting bar 22 is arranged on the housing 21 so as to be slidable in the horizontal direction; a first clamping mechanism 23 is arranged on the housing 21, and the first clamping mechanism 23 is transmission-connected to the mounting bar 22; a second clamping mechanism 24 is arranged on the mounting bar 22, and when the mounting bar 22 drives the second clamping mechanism 24 to move toward the turntable 11, the first clamping mechanism 23 is in a loose state, and when the mounting bar 22 drives the second clamping mechanism 24 to move toward the side away from the turntable 11, the first clamping mechanism 23 clamps the firework tube 3 in one of the assembly grooves 111 on the turntable 11.

[0032] First, the firework tube 3 is placed on the assembly groove 111 of the turntable 11 manually or by a conveying mechanism. The rotation of the turntable 11 drives the movement of its assembly groove 111, thereby driving the firework tube 3 located in the assembly groove 111 to move until the firework tube 3 is aligned with the plugging mechanism 2. The initial position of the second clamping mechanism 24 is on the side of the housing 21 away from the turntable 11. A feeding mechanism (not shown in the figure) for conveying the fuse 31 is also provided beside the housing 21. When it is necessary to plug the fuse 31, the feeding mechanism drives the fuse 31 into the second clamping mechanism 24. The second clamping mechanism 24 clamps the fuse 31. The sliding of the mounting strip 22 of the plugging mechanism 2 drives the second clamping mechanism 24 connected thereto, and the movement of the mounting strip 22 drives the second clamping mechanism 24 and the clamped fuse 31 to slide towards the turntable 11 until the fuse 31 is inserted into the firework tube 3. At this time, the second clamping mechanism 24 releases the clamping of the fuse 31, and the mounting strip 22 drives the second clamping mechanism 24 to reset. When the mounting strip 22 slides towards the side away from the turntable 11, it drives the first clamping mechanism 23 connected thereto in a transmission manner, so that the first clamping mechanism 23 clamps the sticker of the firework tube 3, enabling the sticker to wrap the fuse 31. Since the mounting strip 22 drives the first clamping mechanism 23 to wrap the sticker on the firework tube 3 when resetting, when the turntable 11 subsequently drives the firework tube 3 to move to the side of the housing 21, it will collide with the first clamping mechanism 23. Therefore, after the second clamping mechanism 24 clamps the fuse 31, it slides a certain distance towards the turntable 11, causing the first clamping mechanism 23 to be in a state of loosening the firework tube 3, enabling the firework tube 3 to pass through the first clamping mechanism 23 smoothly, thereby avoiding the collision between the first clamping mechanism 23 and the firework tube 3 transported by the subsequent turntable 11 to the side of the housing 21 and improving the stability of the equipment. Through the cooperation of the turntable 11, the assembly groove 111 and the plugging mechanism 2, it is helpful to improve the plugging efficiency of the firework fuse 31. The structure is simple and easy to operate. The setting of driving the first clamping mechanism 23 by the mounting strip 22 enables it to press the sticker on the firework tube 3, making the fuse 31 stably located in the firework tube 3 and improving the effect of plugging the fuse 31. At the same time, the mounting strip 22 can also drive the second clamping mechanism 24. The second clamping mechanism 24 can convey the fuse 31 and plug it into the firework tube 3, reducing the driving source on the plugging mechanism 2 and facilitating the reduction of the cost of the entire equipment.

[0033] Such as Figures 1 to 4As shown: the first clamping mechanism 23 includes two clamping components 231, and the two clamping components 231 are located at the top and bottom of the shell 21 in a mirror-symmetrical state. The two clamping components 231 each include a clamping claw 2311, a first connecting rod 2313 and two second connecting rods 2314 parallel to each other. One end of the two second connecting rods 2314 is hinged to the shell 21, and the two second connecting rods 2314 are parallel to each other. One end and the middle of the first connecting rod 2313 are hinged to the other end of the two second connecting rods 2314 respectively. The clamping claw 2311 is connected to the other end of the first connecting rod 2313, and the clamping claw 2311 is located between the turntable 11 and the shell 21, and one of the second connecting rods 2314 is transmission connected to the mounting bar 22.

[0034] The sliding of the mounting bar 22 can drive the second connecting rod 2314 connected to it, so that the second connecting rod 2314 can drive the first connecting rod 2313 hinged to it to move, so that the first connecting rod 2313 can rotate with the hinge point of the second connecting rod 2314 as the center of the circle. Since the two second connecting rods 2314 are parallel to each other, the first connecting rod 2313 rotates horizontally toward the center of the shell 21. The movement of the first connecting rod 2313 drives the clamping claw 2311 connected to it, and because the two clamping assemblies 231 are in a mirror-symmetrical state, the clamping claws 2311 on the two clamping assemblies 231 can slide toward the center of the shell 21 at the same time until the two clamping claws 2311 wrap the sticker on the firework tube 3, so that the lead 31 can be fixed on the firework tube 3, which improves the automation of the equipment while helping to reduce the workload of the staff.

[0035] like Figures 1 to 4 As shown, the clamping claw 2311 includes two inclined clamping rods 2312, the two clamping rods 2312 are V-shaped, and the clamping claws 2311 of the two clamping assemblies 231 are arranged in a staggered state so that the two clamping claws 2311 will not collide with each other when approaching each other.

[0036] By means of two V-shaped clamping rods 2312, when the clamping claws 2311 of the two clamping assemblies 231 approach each other, a diamond-shaped clamping area can be formed between the two. As the two first connecting rods 2313 approach each other, the diamond-shaped area between the two clamping claws 2311 gradually becomes smaller until the sticker at the end of the firework tube 3 is wrapped, so that the fuse 31 and the sticker adhere together, thereby improving the stability of the fuse 31 in the firework tube 3, reducing the steps for workers to fix the fuse 31, alleviating the burden on staff, and improving work efficiency.

[0037] like Figures 3 to 8As shown in the figure: A first slide rail 211 extending in the horizontal direction is provided on the housing 21. The mounting strip 22 is slidably arranged on the first slide rail 211. Four mounting shafts 212 are arranged inside the housing 21. Two second connecting rods 2314 of the two clamping assemblies 231 are respectively sleeved on the four mounting shafts 212. A first gear 213 and a second gear 214 are respectively arranged on two of the co-column mounting shafts 212. Rack teeth 221 are provided on both the top and bottom of the mounting strip 22 of the two clamping assemblies 231. The first gear 213 and the second gear 214 are both meshed and connected with the rack teeth 221.

[0038] The sliding of the mounting strip 22 drives the movement of the rack teeth 221 connected thereto. The movement of the rack teeth 221 drives the rotation of the first gear 213 and the second gear 214 meshed therewith. The rotation of the first gear 213 and the second gear 214 drives the rotation of the mounting shaft 212. The mounting shaft 212 drives the rotation of the second connecting rod 2314. Since the two rack teeth 221 are respectively located at the top and bottom of the mounting strip 22, the rotation directions of the first gear 213 and the second gear 214 are opposite, so that the two clamping assemblies 231 can move relatively, facilitating the clamping and loosening of the sticker on the fireworks tube 3.

[0039] As Figures 3 to 8 shown in the figure: A second slide rail 222 extending in the horizontal direction is provided on the mounting strip 22. The second clamping mechanism 24 is slidably located on the second slide rail 222. A transmission assembly 223 for driving the second clamping mechanism 24 to slide on the second slide rail 222 is arranged inside the housing 21. When the mounting strip 22 slides towards the turntable 11 side, the transmission assembly 223 will drive the second clamping mechanism 24 to slide towards the side of the second slide rail 222 close to the turntable 11. When the mounting strip returns to its original position, the transmission assembly 223 will drive the second clamping mechanism 24 to slide towards the side of the second slide rail 222 away from the turntable 11.

[0040] When the installation bar 22 drives the second clamping mechanism 24 to move, since the moving distance of the installation bar 22 is limited, the insertion of the lead wire 31 into the fireworks tube 3 driven by the second clamping mechanism 24 will be restricted. In order to better drive the lead wire 31 to insert into the fireworks tube 3, when the installation bar 22 slides towards the turntable 11, the transmission component 223 will drive the second clamping mechanism 24 to slide towards the side of the second slide rail 222 close to the turntable 11, thereby increasing the distance between the second clamping mechanism 24 and the turntable 11, enabling the lead wire 31 to be better inserted into the fireworks tube 3; when the installation bar resets, the transmission component 223 will drive the second clamping mechanism 24 to slide towards the side of the second slide rail 222 away from the turntable 11, making the second clamping mechanism 24 closer to the feeding mechanism, enabling the feeding mechanism to better convey the lead wire 31 to the second clamping mechanism 24. The transmission component 223 can greatly increase the moving distance of the second clamping mechanism 24, further improving the stability of the lead wire 31 during material receiving and insertion.

[0041] As Figures 5 to 11 shown: The transmission component 223 includes a swing rod 2231, a drive rod 2232, a tension spring 2234, and a sliding rod 2233. The swing rod 2231 is rotatably located above the first slide rail 211. The sliding rod 2233 is sleeved on one end of the drive rod 2232, and the sliding rod 2233 is slidably arranged on the second slide rail 222 of the installation bar 22. A third slide rail 2235 is provided on the drive rod 2232, and the bottom of the swing rod 2231 is slidably arranged on the third slide rail 2235. The two ends of the tension spring 2234 are respectively sleeved on the sliding rod 2233 and the bottom of the swing rod 2231. The second clamping mechanism 24 is sleeved on the sliding rod 2233.

[0042] The tension spring 2234 is used to support the sliding rod 2233 and the swing rod 2231 through its own elastic force, so that the two are separated from each other. When the mounting bar 22 slides toward one side of the turntable 11, the second slide rail 222 on the mounting bar 22 drives the driving rod 2232 to move, and the movement of the driving rod 2232 drives the swing rod 2231 connected thereto. Since the bottom of the swing rod 2231 is slidably arranged on the third slide rail 2235 of the driving rod 2232, when the mounting bar 22 drives the driving rod 2232 to move below the swing rod 2231, the bottom of the swing rod 2231 can move along the third slide rail The rail 2235 slides, thereby compressing the tension spring 2234. As the mounting bar 22 continues to move, the swing arm 2231 rotates to the side close to the turntable 11. At this time, the tension spring 2234 releases the pressure, and the elastic force of the tension spring 2234 pushes the swing arm 2231 and the sliding rod 2233 to separate, so that the sliding rod 2233 slides on the second slide rail 222 toward the end close to the turntable 11 until the tension spring 2234 returns to its original state. When the mounting bar 22 is reset, the above steps are repeated in the reverse direction, so that the sliding rod 2233 can slide to the end of the second slide rail 222 away from the turntable 11. The movement of the sliding rod 2233 drives the second clamping mechanism 24 connected thereto, so that the second clamping mechanism 24 can slide between the two ends of the second slide rail 222 during the movement of the mounting bar 22. This can greatly increase the movement distance of the second clamping mechanism 24, so that the stability of the lead 31 is further improved.

[0043] like Figures 1 to 3 and Figure 7 As shown: The housing 21 is also provided with a driving assembly 25 for driving the mounting bar 22 to slide. The driving assembly 25 includes a screw rod 251, a first rotation drive motor 252, two mounting plates 253 and a slider 254. The slider 254 is arranged on the first slide rail 211 and can slide horizontally. The mounting bar 22 is fixedly connected to the slider 254. The two mounting plates 253 are respectively located at both ends of the sliding direction of the slider 254. The screw rod 251 is horizontally rotatable and is located between the two mounting plates 253. The first rotation drive motor 252 is located on one of the mounting plates 253. The screw rod 251 is transmission-connected to the first rotation drive motor 252. The slider 254 is sleeved on the screw rod 251 and engaged with its thread.

[0044] By starting the first rotary drive motor 252, the output shaft of the first rotary drive motor 252 drives the rotation of the lead screw 251 which is in transmission connection with it. The rotation of the lead screw 251 drives the movement of the slider 254 which is in threaded cooperation with it, enabling the slider 254 to slide along the first slide rail 211. The movement of the slider 254 drives the mounting bar 22 which is fixedly connected to it. The movement of the mounting bar 22 can drive the first clamping mechanism 23 and the second clamping mechanism 24 which are connected to it. The setting of the drive assembly 25 facilitates the precise control of the position of the slider 254, which helps to better adjust the feeding and plugging of the lead 31 and improve the stability of the equipment.

[0045] As Figure 5 , Figure 6 and Figure 11 shown in the figure: The second clamping mechanism 24 includes a connection head 241 and two pneumatic grippers 242 provided on the connection head 241. Grooves 2421 which are mutually matched with the lead 31 are provided on both of the two pneumatic grippers 242. The connection head 241 is sleeved on the sliding rod 2233. The two pneumatic grippers 242 are symmetrically arranged on the connection head 241 in a mirror image, and both of the two pneumatic grippers 242 are arranged on the connection head 241 so as to be able to slide in the vertical direction.

[0046] By sleeving the connection head 241 on the sliding rod 2233, the sliding rod 2233 can drive the connection head 241 to slide along the second slide rail 222, so that when the second clamping mechanism 24 slides on the first slide rail 211 along with the mounting bar 22, it can also increase the moving distance by moving on the second slide rail 222 of the mounting bar 22, enabling it to better match different plugging operations and improve the adaptability and stability of the equipment. The setting of the grooves 2421 helps to better clamp the lead 31 and prevent damage to the lead 31 when the gripper is started to clamp the lead 31.

[0047] As Figure 2 and Figure 3 shown in the figure: At one end of the housing 21 far from the turntable 11, a guiding assembly 26 for guiding the lead 31 is further provided. The guiding assembly 26 includes a fixing plate 261 and two guiding wheels 262. The mounting plate 253 is fixedly connected to the housing 21. The two guiding wheels 262 are rotatably arranged on the mounting plate 253. A gap for the lead 31 to pass through is left between the two guiding wheels 262.

[0048] Through the setting of the fixing plate 261 and the guiding wheels 262, the lead 31 sent to the housing 21 by an external feeding mechanism is guided, enabling the lead 31 to be better clamped by the second clamping mechanism 24 and improving the stability of the equipment.

[0049] As Figure 2As shown in the figure: a discharge plate 12 for guiding the dropped fireworks cylinders 3 is provided at the bottom of the turntable 11, and the discharge plate 12 is inclined.

[0050] Through the setting of the discharge plate 12, the fireworks cylinders 3 assembled on the turntable 11 can be discharged onto the discharge plate 12 when rotating to the bottom of the turntable 11. Through the inclined setting of the discharge plate 12, the fireworks cylinders 3 can slide towards the lower level by the action of gravity after falling on the discharge plate 12. Thus, it is convenient to centrally collect the fireworks cylinders 3 with the leads 31 assembled, improve the automation degree of the equipment, and reduce the burden on the staff.

[0051] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent shall be subject to the appended claims.
