[0034] In addition, the drawings are not drawn to scale 1:1, and the relative size of each element is only drawn by example in the drawings, not necessarily drawn according to the true scale.

[0035] Please refer to Figure 1 And Figure 2 The fireworks lead detection equipment 100 in the preferred embodiment of the utility model includes a rack 110, a detection platform 120, a lifting driving mechanism 130 and a detection mechanism 140.

[0036] Please refer to Figure 3 The detection platform 120 is installed on the rack 110 and has a detection table top 121. The detection table top 121 has a feeding station 122 and a detection station 123 arranged at intervals along a first direction 10. When the fireworks lead detection equipment 100 is located in the horizontal plane, the detection table top 121 is a horizontal plane, and the first direction 10 is a horizontal direction.

[0037] The lifting driving mechanism 130 is in transmission connection with the detection platform 120 and is used to drive the detection table to lift along a second direction 20 perpendicular to the detection table top 121. When the fireworks lead detection equipment 100 is located in the horizontal plane, the second direction 20 is a vertical direction.

[0038] The detection mechanism 140 is installed on the rack 110 and is used to detect the lead of the fireworks lump 40 located in the detection station 123.

[0039] In actual use, the above-mentioned firework lead detection equipment 100 is usually arranged at the downstream end of the firework group pot machine, that is, the detection platform 120 has one end of the feeding station 122 connected with the discharging end of the workbench of the firework group pot machine, so that the firework lumps 40 assembled on the firework group pot machine are sequentially queued and pushed through the discharging end of the workbench to enter the detection station 123. The height of the workbench of the firework group pot machine needs to be adjusted according to the size and specification of the firework lumps 40 to be assembled. In the process of firework production, if the size and specification of the firework lumps 40 change, the height of the workbench of the firework group pot machine used to assemble the firework lumps 40 will also be adjusted accordingly, at this time, the detection platform 120 can be driven to rise or fall by the lifting driving mechanism 130, so that one end of the detection platform 120 with the feeding station 122 can still be connected with the discharging end of the workbench of the firework group pot machine, so that the firework lumps 40 assembled on the firework group pot machine can be sequentially queued and pushed into the detection station 123, so that the subsequent detection mechanism 140 can detect the lead of the firework lumps 40 in the detection station 123. Therefore, the above-mentioned firework lead detection equipment 100 can be used for lead detection of firework lumps 40 of various sizes and specifications, has high adaptability, and can reduce the detection cost of batch detection of firework leads of different sizes and specifications.

[0040] In some embodiments, the lifting driving mechanism 130 is a driving motor. A plurality of transmission screw holes (not shown) are formed at intervals on the detection platform 120. The transmission screw holes can be threaded holes directly formed on the detection platform 120, or can be threaded holes obtained by fixing a nut seat or other parts on the detection platform 120.

[0041] The firework lead detection equipment 100 further comprises a transmission mechanism 150. The transmission mechanism 150 comprises a plurality of parallel and spaced transmission lead screws 151. Each transmission lead screw 151 is rotatably mounted on the rack 110, and the longitudinal direction thereof is consistent with the second direction 20. That is, the transmission lead screws 151 are vertically arranged. The plurality of transmission lead screws 151 are respectively and correspondingly threaded in and screwed to the plurality of transmission screw holes. Thus, the transmission lead screws 151 and the detection platform 120 together constitute a lead screw mechanism. The plurality of transmission lead screws 151 are sequentially connected by transmission rods 152. The two ends of each transmission rod 152 are respectively connected with the corresponding two transmission lead screws 151 through a worm and gear assembly. Any two adjacent transmission rods 152 are connected through a bevel gear transmission assembly 154. In this way, the transmission rods 152 are sequentially connected through the bevel gear transmission assembly 154; the output end of the driving motor is connected with one of the transmission rods 152.

[0042] The plurality of transmission rods 152 can be the same structure or different structures. The driving motor can be a single output motor or a double output motor. When the driving motor is a single output motor, the output end of the driving motor is in transmission connection with one end of the transmission rod 152. When the driving motor is a double output motor, the transmission rod 152 is divided into two coaxially arranged segments, which are in transmission connection with two output shafts of the driving motor, respectively.

[0043] The plurality of transmission lead screws 151 can ensure the stable connection between the detection platform 120 and the rack 110, and ensure the structural stability of the detection platform 120 during the detection of the firework lump 40. The transmission rod 152, the bevel gear transmission assembly 154, the worm gear assembly, and the transmission lead screw 151 can ensure that one driving motor can simultaneously drive multiple lead screws to rotate synchronously, so that the detection platform 120 can be smoothly lifted.

[0044] Further, in some embodiments, a first bellow 155 and a second bellow 156 are sequentially sleeved on each transmission lead screw 151. The first bellow 155 and the second bellow 156 are respectively located at two ends of the corresponding transmission screw hole. The two ends of the first bellow 155 are connected with the detection table 121 and the rack 110, respectively, and the second bellow 156 is connected with the detection platform 120 and the corresponding worm gear transmission assembly 153, respectively.

[0045] The first bellow 155 and the second bellow 156 mainly play a protective role, which can prevent external water, dust, oil stains and other impurities from falling on the transmission lead screw 151 to cause the detection platform 120 to be stuck during lifting, thereby improving the use reliability of the firework lead detection equipment 100 and prolonging the service life of the firework lead detection equipment 100.

[0046] In some embodiments, the detection table 121 further has a sorting station 124, a first discharging station 125, and a second discharging station 126. The detection station 123, the sorting station 124, and the first discharging station 125 are sequentially and spaced apart along a third direction which is perpendicular to the first direction 10 and the second direction 20. The sorting station 124 and the second discharging station 126 are spaced apart along the first direction 10.

[0047] The firework lead detection equipment 100 further includes a conveying mechanism 160, a pushing mechanism 170, and a control device (not shown). The conveying mechanism 160 is installed on the detection platform 120 and is configured to move the firework lump 40 on the detection station 123 in the third direction 30 towards the sorting station 124. The pushing mechanism 170 is configured to push the firework lump 40 on the sorting station 124 in the first direction 10 towards the second discharging station 126.

[0048] The control device is connected with the detection mechanism 140, the conveying mechanism 160 and the pushing mechanism 170 respectively, and is used for controlling the detection station 123 to start when the firework lump 40 reaches the detection station 123, and is used for controlling the conveying mechanism 160 or the pushing mechanism 170 to operate according to the detection signal after receiving the detection signal sent by the detection mechanism 140, so as to move the firework lump 40 in the detection station 123 to the first discharging station 125 or the second discharging station 126 through the sorting station 124.

[0049] In actual use, after the detection mechanism 140 completes the detection of the firework lump 40 in the detection station 123, the detection result is transmitted to the control device, the control device controls the conveying mechanism 160 to operate, so as to convey the detected firework lump 40 from the detection station 123 to the sorting station 124; if the detection result shows that the quality of the lead wire of the firework lump 40 is unqualified, the control device controls the conveying mechanism 160 to stop operating, and controls the pushing mechanism 170 to operate, so as to push the unqualified firework lump 40 from the sorting station 124 to the second discharging station 126; if the detection result shows that the quality of the lead wire of the firework lump 40 is qualified, and after receiving the detection result of the next firework lump 40, the control device controls the conveying mechanism 160 to continue operating, so as to convey the next detected firework lump 40 from the detection station 123 to the sorting station 124, and the previous qualified firework lump 40 is pushed to the first discharging station 125 by the next detected firework lump 40, so that the automatic sorting of the firework lump 40 after the detection of the lead wire is realized, which is helpful to further improve the detection efficiency of the firework lead wire.

[0050] Further, in some embodiments, the detection table 121 is provided with a long strip-shaped avoiding hole 127 along the third direction 30. The conveying mechanism 160 comprises a conveying sliding seat 161 slidably installed on the detection platform 120, a conveying plate 162 installed on the conveying sliding seat, a first stop strip 163, a second stop strip 164, a conveying lifting driving member 165 and a conveying driving member (not shown in the figure). The conveying plate 162 is located directly below the detection table 121. The first stop strip 163 and the second stop strip 164 are fixed on the conveying plate 162 along the third direction 30 and are aligned with the long strip-shaped avoiding hole 127. The conveying lifting driving member 165 is in transmission connection with the conveying plate 162 and is used for driving the conveying plate 162 to ascend and descend along the second direction 20. The conveying driving member is in transmission connection with the conveying sliding seat 161 and is used for driving the conveying sliding seat 161 to drive the conveying plate 162 to reciprocate along the third direction 30 between the detection station 123 and the sorting station 124.

[0051] The control device is electrically connected with the conveying lifting driving member 165 and the conveying driving member respectively, and is used for controlling the conveying lifting driving member 165 to drive the conveying plate 162 to rise until at least part of the first stop bar 163 and the second stop bar 164 passes through the long strip-shaped avoiding hole 127 to reach above the detection table 121 when the conveying plate 162 reaches the detection station 123, is used for controlling the conveying lifting driving member 165 to drive the conveying plate 162 to descend until the first stop bar 163 and the second stop bar 164 are completely below the detection table 121 when the conveying plate 162 is located at the detection station 123, and is used for controlling the detection mechanism 140 to start when the firework lump 40 reaches the detection station 123 and is clamped between the first stop bar 163 and the second stop bar 164.

[0052] In actual use, the firework lump 40 at the detection station 123 is clamped between the first stop bar 163 and the second stop bar 164, so as to limit the position of the firework lump 40 at the detection station 123 from the third direction 30, thereby improving the accuracy and reliability of the detection of the fuse; when it is needed to convey the firework lump 40 from the detection station 123 to the sorting station 124, the conveying driving member drives the conveying sliding seat 161 to slide in the third direction 30 towards the sorting station 124, so that the first stop bar 163 and the second stop bar 164 can be used to move the firework lump 40 from the detection station 123 to the sorting station 124; when the firework lump 40 reaches the sorting station 124, the control device controls the conveying lifting driving member 165 to drive the conveying plate 162 to lower the first stop bar 163 and the second stop bar 164 until the first stop bar 163 and the second stop bar 164 are completely lowered below the detection table 121, and then controls the conveying driving member to drive the conveying sliding seat 161 to slide in the third direction 30 towards the detection station 123; when the conveying plate 162 reaches the detection station 123, the control device controls the conveying lifting driving member 165 to drive the conveying plate 162 to rise until the first stop bar 163 and the second stop bar 164 rise to at least pass through the long strip-shaped avoiding hole 127 to reach above the detection table 121.

[0053] Further, in some embodiments, the long strip-shaped avoiding hole 127 is a plurality of long strip-shaped avoiding holes. The plurality of long strip-shaped avoiding holes 127 are arranged in parallel and at intervals along the first direction 10. The first stop bar 163 and the second stop bar 164 are both a plurality of first stop bars and a plurality of second stop bars. The plurality of first stop bars 163 and the plurality of second stop bars 164 are respectively aligned with the plurality of long strip-shaped avoiding holes 127 one by one.

[0054] In this way, the plurality of first stop bars 163 and the plurality of second stop bars 164 can limit the placement position and the placement posture of the firework lump 40 at the detection station 123, so as to ensure that the detection mechanism 140 can more accurately and reliably detect the situation of the fuse in each paper tube during subsequent detection of the fuse, thereby further improving the accuracy and reliability of the detection of the fuse of the firework.

[0055] Please refer to Figure 4 Further, in some embodiments, the firework lead detection device 100 further comprises two guide structures 181, a limiting plate 183 and a limiting lifting driving member 184. The two guide structures 181 are oppositely and spacedly arranged along the third direction 30 at the feeding station 122. A guide channel 182 for guiding the feeding direction of the firework lump 40 is formed between the two guide structures 181. The opening direction of the guide channel 182 close to the one end of the detection station 123 is consistent with the first direction 10. The limiting plate 183 is movably installed on the rack 110 along the second direction 20. The limiting lifting driving member 184 is used to drive the limiting plate 183 to descend or ascend until the limiting plate 183 contacts with the end surface of the firework lump 40 at the detection station 123 or the limiting plate 183 leaves the firework lump 40 at the detection station 123. The control device is used to control the detection mechanism 140 to start when the firework lump 40 reaches the detection station 123 through the guide channel 182 and the limiting plate 183 ascends to leave the firework lump 40.

[0056] In actual use, the firework lump 40 is sequentially queued into the guide channel 182 under the action of the conveying power provided by the firework group pot machine, that is, the firework lump 40 in front of the guide channel 182 continues to move forward under the pushing of the firework lump 40 moving behind; the limiting plate 183 is driven by the limiting lifting driving member 184 to descend to a specified height, at this time, the firework lump 40 pushed out from the guide channel 182 enters between the first and second stoppers 163 and 164 of the detection station 123 until the end surface of the firework lump 40 abuts against the limiting plate 183, so as to facilitate the subsequent lead detection of the firework lump 40 by the detection mechanism 140. Therefore, the above-mentioned two guide structures 181 guide the feeding direction and the placing posture of the firework lump 40, so that the firework lump 40 can accurately enter between the first and second stoppers 163 and 164 of the detection station 123 in a correct posture after being guided by the guide channel 182, and the placing position and the placing posture of the firework lump 40 at the detection station 123 in the feeding direction are limited by the limiting plate 183, so as to further ensure that the detection mechanism 140 can accurately and reliably detect the lead condition in each paper tube of the firework lump 40, and further improve the accuracy and reliability of the firework lead detection device 100.

[0057] Further, in some embodiments, the firework fuse detection device 100 further comprises a material clamping mechanism 190. The material clamping mechanism 190 comprises a clamping structure 191 and a clamping lifting driving member 192. The material clamping mechanism 190 is arranged directly above the detection station 123. The clamping lifting driving member 192 is in transmission connection with the clamping structure 191 and is used to drive the clamping structure 191 to ascend or descend along the second direction 20. The control device is in electrical connection with the clamping driving member and is used to control the clamping driving member to drive the clamping structure 191 to descend until the clamping structure 191 abuts against the firework lump 40 when the firework lump 40 reaches the detection station 123 and is located between the first stop 163 and the second stop 164.

[0058] In actual use, when the firework lump 40 reaches the specified position of the detection station 123, the control device controls the clamping driving member to drive the clamping structure 191 to descend to press the firework lump 40 on the detection station 123, so as to ensure that the firework lump 40 does not deviate during subsequent fuse detection, thereby further improving the reliability of firework fuse detection.

[0059] Further, in some embodiments, the clamping structure 191 comprises a pressing seat 1911, a guide rod 1912, a pressing block 1913, an elastic member 1914 and a limiting member 1915. The pressing seat 1911 is in transmission connection with the clamping driving member and is formed with a guide sliding hole. The guide rod 1912 is slidably arranged in the guide sliding hole and is fixedly connected with the pressing block at an end thereof facing the detection station 123. The elastic member 1914 is used to provide an elastic force for driving the guide rod 1912 to move the pressing block in the direction facing the detection station 123. The limiting member 1915 is detachably installed at an end of the guide rod 1912 away from the pressing block 1913 and is located on a side of the pressing seat 1911 away from the clamping seat.

[0060] The limiting member 1915 is arranged to prevent the guide rod 1912 from sliding out of the guide sliding hole and thus causing the guide rod 1912 to be separated from the pressing seat 1911 after the pressing block 1913 leaves the firework lump 40. The elastic member 1914 can be a compression spring, a metal spring piece or the like.

[0061] In this way, when the firework lump 40 is pressed on the detection station 123 by the clamping structure 191, the pressing block 1913 adaptively provides a pressing force to the firework lump 40 under the action of the elastic force provided by the elastic member 1914, so as to ensure that the firework lump 40 remains stationary on the detection station 123 even when the firework fuse detection device 100 vibrates or moves, and to reduce the probability of the firework lump 40 being damaged.

[0062] In some embodiments, the detection mechanism 140 comprises a lifting seat 141, a detection lifting driver 142, a translation seat 143, a translation driver 144, a visual detection device 145, and a lead height detection sensor 146. The lifting seat 141 is mounted on the rack 110. The detection lifting driver 142 is in driving connection with the lifting seat 141 and is used to drive the lifting seat 141 to lift along the second direction 20. The translation seat 143 is slidably mounted on the lifting seat 141. The translation driver 144 is in driving connection with the translation seat 143 and is used to drive the translation seat 143 to slide along a third direction 30 which is perpendicular to the first direction 10 and the second direction 20. The visual detection device 145 is mounted on the translation seat 143. The lead height detection sensor 146 is mounted on the rack 110 and is located directly above the detection station 123.

[0063] Therefore, when there is no firework block 40 on the detection station 123 or the lead detection of the firework block 40 on the detection station 123 is not needed, the detection lifting driver 142 drives the lifting seat 141 to lift the visual detection device 145 upward;

[0064] When the detection of the firework block 40 on the detection station 123 is needed, the detection lifting driver 142 drives the lifting seat 141 to lift the visual detection device 145 along the second direction 20, so as to ensure that the visual detection device 145 can effectively detect the lead in each paper tube of the firework block 40. The translation driver 144 drives the translation seat 143 to drive the visual detection device 145 to translate along the third direction 30, so as to ensure that the visual detection device 145 can effectively detect the lead in each column of paper tubes of the firework block 40. The lead height detection sensor 146 simultaneously detects the lead height of the firework block 40, so as to ensure that the detection mechanism 140 can comprehensively and effectively detect the lead of the firework block 40, and further improve the comprehensiveness and reliability of the firework lead detection.
