Description

Technical Field

[0001] The utility model relates to the technical field of facial mask packaging, in particular to a material feeding and grabbing mechanism for a facial mask packaging machine. Background Art

[0002] The mask packaging machine is an automated packaging equipment specially used for mask products. It can complete a series of packaging processes such as mask filling, sealing, printing date, cutting, counting, etc. The mask packaging machine usually includes a feeding system, a molding system, a sealing system, a printing system, a cutting system, and a discharging system. With the improvement of the level of industrial automation, the production of masks also tends to be fully automated. The feeding and grabbing mechanism can realize the automatic supply of mask materials without manual intervention, which greatly improves production efficiency.

[0003] The loading and grabbing mechanism of traditional facial mask packaging machines is usually based on a simple mechanical design. The facial mask materials are usually fed into the feed port of the machine manually. The loading and grabbing mechanism is usually composed of an electric clamp, which opens and closes under the action of the control signal to grab the facial mask material. After grabbing the facial mask material, the clamp moves with the conveyor belt or robotic arm to transport the facial mask material to the next packaging process. After reaching the designated position, the clamp opens to release the facial mask material, completing the loading process.

[0004] The above-mentioned traditional feeding and grabbing mechanism can usually only adapt to products of specific specifications and types. For mask materials of different sizes or shapes, the clamps may need to be replaced or readjusted. The feeding speed of the traditional mechanism is usually slow and cannot be perfectly matched with the high-speed packaging machine, which limits the improvement of production efficiency. For new mask materials or special packaging requirements, the traditional feeding and grabbing mechanism may be difficult to adapt and require a long time for modification and debugging.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Specifically, the first gear 3 is meshed with the internal rack plate 4. When the motor 2 rotates, the first gear 3 drives the rack plate 4 to make reciprocating linear motion along the inside of the shell 1. The first limit plate 5 is fixed to the rack plate 4, and it slides inside the shell 1 to limit the stroke of the rack plate 4 to avoid damage to the mechanism caused by excessive movement. The first cylinder 7, as an actuator, can drive the connecting block 8 to slide inside the shell 1, thereby realizing up and down movement. There is a guide column 12 inside the connecting plate 9 under the connecting block 8 to ensure that the fixed plate 13 maintains a stable posture when the connecting block 8 moves up and down. A spring 11 is installed on the outer wall of the connecting rod 10. The spring 11 provides a certain elastic force to help the suction cup assembly maintain a stable posture and can provide a certain buffering effect when sucking the mask. When the motor 2 drives the entire mechanism to move to an appropriate position, the suction cup assembly can suck the mask and fix it. After sucking the mask, the motor 2 reverses and drives the rack plate 4 to move in the opposite direction. The mask is transported from the loading position to the conveyor belt 15 through the mechanism composed of the connecting block 8, the connecting plate 9, the connecting rod 10 and the spring 11.

[0027] Reference Figure 2 and Figure 3The suction cup assembly includes a fixing plate 13 , an outer wall of the fixing plate 13 is fixedly connected to one end of the spring 11 , a vacuum suction cup 14 is fixedly connected inside the fixing plate 13 , and an outer wall of the guide column 12 is slidably connected inside the fixing plate 13 .

[0028] Specifically, the fixed plate 13 is the main supporting structure of the suction cup assembly, which is fixedly connected through the other end of the spring 11, so that the suction cup assembly can remain stable and slide along the guide column 12. The vacuum suction cup 14 is a key component for sucking the mask, and it is internally fixedly connected to the fixed plate 13. The vacuum suction cup 14 can generate negative pressure under the drive of a power source, thereby sucking the mask material. The outer wall of the guide column 12 is slidably connected to the inside of the fixed plate 13 to ensure the straight trajectory of the suction cup assembly during movement to avoid deviation.

[0029] Reference Figure 4 and Figure 5 The outer wall of the shell 1 is fixedly connected to the conveyor belt 15, the outer wall of the vacuum suction cup 14 is arranged above the conveyor belt 15, the outer wall of the shell 1 is fixedly connected to the limit rod 16, the inside of the shell 1 is fixedly connected to the support plate 17, the outer wall of the support plate 17 is fixedly connected to the first support frame 18, the outer wall of the support plate 17 is fixedly connected to the outer shell 19, the outer wall of the support plate 17 is fixedly connected to the second support frame 20, the inside of the first support frame 18 is rotatably connected to the rotating rod 27, one end of the rotating rod 27 is fixedly connected to the second gear 22, the inside of the outer shell 19 is slidably connected to the lifting rod 23, the second gear 22 is meshed with the lifting rod 23, the outer wall of the lifting rod 23 is fixedly connected to the second limit plate 24, the inside of the second support frame 20 is fixedly connected to the second cylinder 21, the output end of the second cylinder 21 is fixedly connected to the fixed frame 26, and one end of the lifting rod 23 is fixedly connected to the placement plate 25.

[0030] Specifically, the conveyor belt 15 is fixed to the outer wall of the shell 1 and is used to transport the mask material from the loading position to the packaging position. The second cylinder 21 serves as an actuator, and its output end is fixedly connected to a fixed frame 26 for driving the lifting and lowering movement of the placement plate 25. The rotating rod 27 is meshed with the lifting rod 23 through the second gear 22 to realize the up and down movement of the lifting rod 23. One end of the lifting rod 23 is fixedly connected to the placement plate 25 for carrying the mask material. The second limit plate 24 limits the stroke of the lifting rod 23.

[0031] Working principle: When a mask packaging machine feeding and grabbing mechanism is needed, the motor 2 is used to drive the first gear 3 to drive the rack plate 4 to slide inside the shell 1, and the first limit plate 5 is used to maintain the stability of the sliding when sliding. The first cylinder 7 drives the connecting block 8 to drive the connecting plate 9 to move up and down, and the connecting rod 10 slides inside the fixed plate 13, and a spring 11 is added to the outside. The first cylinder 7 moves downward to drive the vacuum suction cup 14 to absorb the mask, and the connecting rod 10 uses the rebound characteristics of the spring 11 to move up and down inside the fixed plate 13. Sliding improves the stability of grabbing and reduces damage to the mask. By setting the guide column 12, the fixed plate 13 is prevented from shifting when floating up and down. The second cylinder 21 drives the fixing frame 26 to drive the lifting rod 23 to move up and down. The mask is placed in the placement plate 25 and the limiting rod 16, and the placement plate 25 is driven to move up and down by the second cylinder 21. The second gear 22 is driven to rotate when the lifting rod 23 moves up and down, and the rotating rod 27 is driven to move by the second gear 22 on both sides, thereby improving the stability of the lifting rod 23 when the second cylinder 21 drives the lifting rod 23 to move up and down.
