In the cosmetics production line, the automatic conveying of the packaging cans is an important part of realizing production automation, and the conveying performance can directly determine the output of the production line and product quality control. The cosmetics conveying device in the prior art is usually unable to cover the cosmetics cans during the conveying process, making it impossible to effectively package the cosmetics cans, increasing the risk during the conveying process, and may even affect the quality of the cosmetics. Summary of the invention

[0006] Furthermore, the steering mechanism includes an inner rod fixedly mounted on the material distribution box, a plurality of rotating wheel frames are rotatably mounted on the inner rod, a rotating wheel is rotatably mounted on the rotating wheel frame, a winding rope is wound between the rotating wheel and the driven roller, a winding rope is wound between the rotating wheel and the active roller, and the rotating wheel frame cooperates with the sliding frame.

[0007] Furthermore, the output mechanism includes a front motor fixedly mounted on the material distribution box, a front gear fixedly mounted on the motor shaft of the front motor, a plurality of driven rollers rotatably mounted on the material distribution box, a sub-gear fixedly mounted on the driven rollers, and a side transmission belt wrapped around the front gear and the sub-gear.

[0008] The cosmetic jars are put into the feeding rack, and the discharging motor rotates to drive the motor gear to rotate, thereby driving the driving gear and the driving roller to rotate, thereby driving the two driven rollers to rotate through the transmission belt, and then driving the rotating wheel to rotate through the winding rope.

[0009] The cosmetic jar is located on the lower pressure plate, and the lower pressure spring will be compressed. When the weight of the cosmetic jar is qualified, the lower pressure plate will be pressed down, thereby driving the short rod to rotate, thereby driving the sliding frame to slide in the material distribution box, and the sliding frame pushes all the rotating wheel frames to rotate, thereby making the rotating wheel turn. The rotating wheel rotates and cooperates with the guide wheel to transport the cosmetic jar to the transmission frame. The lower pressure spring rebounds slowly. After the cosmetic jar enters the transmission frame, the lower pressure spring and the lower pressure plate will be reset.

[0010] When the weight of the cosmetic jar is unqualified, that is, too light, the sliding frame will not push the rotating wheel frame to rotate, and the rotating wheel will rotate to transport the cosmetic jar to the driven roller. The front motor rotates to drive the front gear to rotate, thereby driving all the gears to rotate through the side transmission belt, thereby driving the driven roller to rotate and send out the unqualified cosmetic jar.

[0011] Furthermore, the cover dropping device includes a guide wheel rotatably mounted on a transmission frame, a cover feeding cylinder is fixedly mounted on the transmission frame, a conveying motor is fixedly mounted on the transmission frame, a conveying gear is fixedly mounted on the motor shaft of the conveying motor, a plurality of conveying rollers rotatably mounted on the transmission frame, an action gear is fixedly mounted on the conveying rollers, a conveyor belt is wrapped around the conveying gear and the action gear, a can cover is placed in the cover feeding cylinder, and a blocking mechanism is arranged on the cover feeding cylinder.

[0014] When the cosmetic jar reaches the conveying roller, the conveying motor rotates to drive the conveying gear to rotate, thereby driving the action gear to rotate through the conveyor belt, thereby driving the conveying roller to convey the cosmetic jar to the bottom of the cover feeding cylinder. The cosmetic jar is blocked by the baffle plate, and the conveying roller cannot drive the cosmetic jar to continue moving forward.

[0015] The electric cylinder extends, driving the connecting frame to slide along the cover feeding cylinder, thereby driving the cover blocking plate to leave under the can cover, and the can cover falls onto the cosmetic jar. At the same time, the bottle blocking plate leaves the front of the cosmetic jar. When the can cover falls onto the cosmetic jar, the bottle blocking plate has not left the front of the cosmetic jar. At the same time, the connecting frame drives the slide plate and the friction block to push inward, the slide plate spring is compressed, and the friction block holds the next can cover to prevent the next can cover from falling. When the bottle blocking plate completely leaves the front of the cosmetic jar, the conveying roller transports the cosmetic jar to the packaging rack, and then the electric cylinder contracts, driving the bottle blocking plate to return to the initial position. At the same time, the cover blocking plate reaches under the can cover, the friction block no longer presses the can cover, and the slide plate spring is reset.

[0016] Furthermore, the conveying device includes a driving motor fixedly mounted on the packaging frame, a driving gear is fixedly mounted on the motor shaft of the driving motor, a left driven wheel, a right driven wheel, a right driving wheel and a left driving wheel are rotatably mounted on the packaging frame, a right gear is fixedly mounted on the right driving wheel, a left gear is fixedly mounted on the left driving wheel, the driving gear is meshed with the right gear, the right gear is meshed with the left gear, a right driving belt is wrapped around the right driven wheel and the right driving wheel, a left driving belt is wrapped around the left driven wheel and the left driving wheel, and a capping mechanism is provided on the packaging frame.

[0018] Furthermore, the right and left shifting belts rotate in opposite directions, and the left and right fastening belts rotate in the same direction.

[0019] The cosmetic jar and the jar cover arrive on the packaging rack together, and the driving motor rotates to drive the driving gear to rotate, thereby driving the right gear and the right driving wheel to rotate, and at the same time driving the left driving wheel and the left gear to rotate. The right driving wheel and the left driving wheel rotate in opposite directions, thereby driving the left and right toggle belts to rotate in opposite directions, thereby driving the cosmetic jar to move forward on the packaging rack through the grooves on the right and left toggle belts.

[0020] The rotation of the right driving wheel will simultaneously drive the right main fastening gear to rotate, thereby driving the right fastening belt to rotate, and at the same time driving the right middle wheel to rotate, thereby driving the right middle upper wheel to rotate, thereby driving the left middle upper wheel and the left middle wheel to rotate through the upper transmission belt, thereby driving the left fastening belt to rotate.

[0053] The working principle of the cosmetic packaging can conveying device disclosed in the present invention is as follows: the cosmetic can 4 is put in from the feeding rack 102, and the discharging motor 103 rotates to drive the motor gear 104 to rotate, thereby driving the driving gear 105 and the driving roller 120 to rotate, thereby driving the two driven rollers 121 to rotate through the transmission belt 116, thereby driving the rotating wheel 110 to rotate through the winding rope 117. The cosmetic can 4 is located on the lower pressing plate 112, and the pressing spring 113 will be compressed. When the weight of the cosmetic can 4 is qualified, the lower pressing plate 112 will be pressed down, thereby driving the short rod 118 to rotate, thereby driving the sliding frame 119 to slide in the material distribution box 101, and the sliding frame 119 pushes all the rotating wheel frames 123 to rotate, thereby causing the rotating wheel 110 to turn, and the rotating wheel 110 rotates to cooperate with the guide wheel 209 to transport the cosmetic can 4 to the transmission rack 201. The pressing spring 113 rebounds slowly. After the cosmetic can 4 enters the transmission rack 201, the pressing spring 113 and the lower pressing plate 112 will be reset. When the weight of the cosmetic jar 4 is unqualified, that is, too light, the sliding frame 119 will not push the rotating wheel frame 123 to rotate, and the rotating wheel 110 rotates to transport the cosmetic jar 4 to the driven roller 111, and the front motor 106 rotates to drive the front gear 107 to rotate, thereby driving all the gears 108 to rotate through the side transmission belt 109, thereby driving the driven roller 111 to rotate and send out the unqualified cosmetic jar 4. When the cosmetic jar 4 reaches the conveying roller 207, the conveying motor 203 rotates to drive the conveying gear 204 to rotate, thereby driving the action gear 205 to rotate through the conveyor belt 206, thereby driving the conveying roller 207 to convey the cosmetic jar 4 to the bottom of the cover feeding cylinder 202, and the cosmetic jar 4 is blocked by the blocking cover plate 212. At this time, the conveying roller 207 cannot drive the cosmetic jar 4 to continue to move forward. The electric cylinder 210 extends, driving the connecting frame 213 to slide along the cover feeding cylinder 202, thereby driving the blocking cover plate 212 to leave the bottom of the tank cover 208, and the tank cover 208 falls on the cosmetic jar 4. At the same time, the bottle blocking plate 211 leaves the front of the cosmetic jar 4. When the tank cover 208 falls on the cosmetic jar 4, the bottle blocking plate 211 has not left the front of the cosmetic jar 4. At the same time, the connecting frame 213 drives the slide plate 215 and the friction block 214 to push inward, the slide plate spring 216 is compressed, and the friction block 214 supports the next tank cover 208 to prevent the next tank cover 208 from falling. When the bottle blocking plate 211 completely leaves the front of the cosmetic jar 4, the conveying roller 207 transports the cosmetic jar 4 to the packaging rack 301, and then the electric cylinder 210 contracts, driving the bottle blocking plate 211 to return to the initial position, and at the same time, the blocking cover plate 212 arrives under the tank cover 208, the friction block 214 no longer presses the tank cover 208, and the slide plate spring 216 is reset.The cosmetic jar 4 and the jar cover 208 arrive at the packaging rack 301 together, and the driving motor 314 rotates to drive the driving gear 315 to rotate, thereby driving the right gear 316 and the right driving wheel 319 to rotate, and at the same time driving the left driving wheel 322 and the left gear 317 to rotate. The rotation directions of the right driving wheel 319 and the left driving wheel 322 are opposite, thereby driving the left toggle belt 320 and the right toggle belt 303 to rotate in the opposite direction, thereby driving the cosmetic jar 4 to move forward on the packaging rack 301 through the grooves on the right toggle belt 303 and the left toggle belt 320. The rotation of the right driving wheel 319 will simultaneously drive the right main fastening gear 313 to rotate, thereby driving the right fastening belt 305 to rotate, and at the same time driving the right middle wheel 311 to rotate, thereby driving the right middle upper wheel 312 to rotate, thereby driving the left middle upper wheel 308 and the left middle wheel 307 to rotate through the upper transmission belt 310, thereby driving the left fastening belt 309 to rotate. The left middle wheel 307 and the right middle wheel 311 have the same rotation direction, thereby driving the jar cover 208 to rotate on the cosmetic jar 4 through the right fastening belt 305 and the left fastening belt 309, thereby tightening the jar cover 208 to the cosmetic jar 4. When the jar cover 208 is completely tightened, the jar cover 208 will slip with the right fastening belt 305 and the left fastening belt 309, and finally the cosmetic jar 4 is transported out from the end of the packaging rack 301 through the right toggle belt 303 and the left toggle belt 320.
