Description

Technical Field

[0001] The present invention relates to the technical field of mask packaging equipment, in particular to a mask bagging machine. Background Art

[0002] Currently, packaging films (such as plastic films or aluminum-plastic composite films) are usually used to make packaging bags and the masks are packaged therein to protect the masks, keep the masks hygienic, and facilitate storage and carrying.

[0003] The existing mask packaging machine includes a frame, a material receiving mechanism, a bag opening mechanism, a material pushing mechanism and a sealing device. When working, the material receiving mechanism receives materials from the mask production equipment, and then the material receiving mechanism transports the masks to the front of the material pushing mechanism. At this time, the bag opening mechanism opens the pre-placed packaging bag, and then the material pushing mechanism pushes the mask into the packaging bag, so that the mask enters the packaging bag, and the packaging bag containing the mask is transmitted to the sealing device via a transmission belt for sealing.

[0004] The existing mask bagging machine usually has only a single channel for bagging. Since it only has a single channel, the bag-holding mechanism of the existing mask bagging machine usually only includes a set of bag-holding components and a set of clamping components. A set of bag-holding components includes two bag-holding shafts and two bag-holding rods. The bag-holding shafts correspond to the bag-holding rods one by one and are fixedly connected. The end of each bag-holding shaft away from the bag-holding rod is respectively connected to a driving mechanism. When the two bag-holding shafts need to rotate at the same time, the two driving mechanisms work at the same time to drive the two bag-holding shafts to rotate at the same time, thereby driving the two bag-holding rods to rotate, so that the bag mouth of the packaging bag is opened by the two bag-holding rods. The function of the clamping component is to clamp the mask and push the mask into the packaging bag opened by the bag-holding component.

[0005] The existing single-channel bagging mask machine can only bag one mask at a time, so the production efficiency is low and it is not conducive to the rapid production of the factory. Summary of the invention

[0065] The working principle of the present invention is:

[0066] The masks produced by the mask production machine are loaded into a certain discharge frame 1500 connected to the first circulating conveyor belt 1340. When one or a group of masks are completely loaded into the discharge frame 1500, the first material receiving drive mechanism 1310 drives the first circulating conveyor belt 1340 to rotate, so that the discharge frame 1500 moves forward, and the next discharge frame 1500 waits for the masks to be loaded. The above process is repeated until all the discharge frames 1500 connected to the first circulating conveyor belt 1340 are loaded with masks. At this time, the discharge frame 1500 connected to the second circulating conveyor belt 1440 waits at the lower part of the end of the receiving frame 1200 extending out of the frame 100;

[0067] The first material receiving drive mechanism 1310 drives the first circulating conveyor belt 1340 to rotate rapidly, so that all the material discharging frames 1500 on the first material receiving drive mechanism 1310 are quickly moved to the side of the mask moving mechanism close to the material discharging mechanism, and the feeding section 1711 of the pressing rod 1710 can make it easier for the mask to enter under the pressing section 1712, so as to prevent the mask from tilting higher than the pressing section 1712 and causing damage to the mask. When the first material discharging frame 1500 is separated from the pressing section 1712 of the pressing rod 1710, the first circulating conveyor belt 1340 gradually decelerates. When the conveyor belt 1340 rotates and drives the multiple discharge frames 1500 to move, the pressing section 1712 of the pressing rod 1710 can limit the masks to prevent the masks from flying out of the discharge frame 1500 when moving at high speed, and after the first discharge frame 1500 completely separates from the pressing section 1712 of the pressing rod 1710, the first circulating conveyor belt 1340 gradually decelerates, so that the masks in the discharge frame 1500 will not fly out of the discharge frame 1500 due to rapid stopping of movement, and finally each mask in the discharge frame 1500 is correspondingly set in a bagging channel;

[0068] And while the first material receiving drive mechanism 1310 drives the first circulating conveyor belt 1340 to move, the second material receiving drive mechanism 1410 drives the second circulating conveyor belt 1440 to rotate rapidly, so that the material discharging frame 1500 connected to the second circulating conveyor belt 1440 moves to the upper part of one end of the material receiving frame 1200 extending out of the frame 100 to wait for the masks to be loaded, and the other material discharging frames 1500 connected to the second circulating conveyor belt 1440 are on standby;

[0069] When the first material receiving driving mechanism 1310 drives the first circulating conveyor belt 1340 to move, the bag taking rotating driving mechanism 3300 drives the bag taking driving shaft 3410 to rotate, thereby driving the bag taking connecting member 3440 to rotate upward and approach the bag taking opening 3220;

[0070] When the bag taking driving shaft 3410 rotates, the bag taking rod sleeve 3460 and the bag taking frame 3200 rotate relatively, and the bag taking slide bar 3450 slides along the bag taking rod sleeve 3460. Since the bag taking connecting shaft 3420 is fixedly connected to one end of the bag taking slide bar 3450, when the bag taking connecting member 3440 rotates upward, the bag taking connecting shaft 3420 simultaneously performs a circular motion around the axis of the bag taking driving shaft 3410 and a rotational motion around the central axis of the bag taking connecting shaft 3420 itself, and finally makes the bag taking suction cup 3432 on the suction cup frame 3431 connected to the bag taking connecting shaft 3420 face the bag taking opening 3220.

[0071] When the bag taking suction cup 3432 faces the bag taking opening 3220, the bag taking suction cup 3432 works to attract the mask packaging bag by negative pressure, and then the bag taking rotation drive mechanism 3300 drives the bag taking drive shaft 3410 to rotate, so that the bag taking vacuum suction cup assembly is reset;

[0072] After the bag taking vacuum suction cup assembly is reset, each mask packaging bag is set in a corresponding bagging channel, and the opening of the mask packaging bag faces the receiving rack 1200; at this time, the bag opening vacuum suction cup 2520 works to suck the open end of the mask packaging bag to open the opening of the mask packaging bag;

[0073] After the bag opening vacuum suction cup 2520 works, that is, after the opening of the mask packaging bag is opened, the first driving mechanism 2340 and the second driving mechanism 2440 work simultaneously, and through the action of the first connecting member 2330 and the second connecting member 2430, the plurality of first bag-supporting rods 2310 and the plurality of second bag-supporting rods 2410 are driven to rotate simultaneously, so that the first bag-supporting rods 2310 and the second bag-supporting rods 2410 located in the same bag-supporting mechanism move away from each other and enter into the mask packaging bag, and the first bag-supporting rods 2310 and the second bag-supporting rods 2410 respectively abut against two opposite side walls of the mask packaging bag, so as to keep the opening of the mask packaging bag in an open state and provide the first clamping member 4361 and the second clamping member 4362 with enough space to enter into the mask packaging bag;

[0074] When the material discharging frame 1500 is correspondingly arranged in the bagging channel, the horizontal driving mechanism 4230 drives the movable frame 4220 to slide in the direction of the material discharging mechanism, and the clamping mechanism also slides in the direction of the material discharging mechanism with the movable frame 4220 until the mask is located between the first clamping member 4361 and the second clamping member 4362; then the second vertical driving mechanism 4320 drives the first clamping member 4361 to move in the vertical direction toward the second clamping member 4362, and at the same time, the first vertical driving mechanism 4310 drives the push plate 43 30 drives the first clamping member 4361 and the second clamping member 4362 to rise together, so that the first clamping member 4361 and the second clamping member 4362 perform the mask clamping action, and the anti-sticking groove 1530 provides a space for inserting the two parts of one end of the second clamping member 4362 separated by the avoidance groove 4363, which can increase the clamping length of the second clamping member 4362, so that the second clamping member 4362 can clamp the mask with a larger area, so that the first clamping member 4361 and the second clamping member 4362 have a better clamping effect on the mask;

[0075] After the first clamping member 4361 and the second clamping member 4362 clamp the mask, the first vertical driving mechanism 4310 then drives the first clamping member 4361 and the second clamping member 4362 to move upward, and the horizontal driving mechanism 4230 drives the moving frame 4220 to continue to slide in the direction of the discharging mechanism, so that the mask clamped by the first clamping member 4361 and the second clamping member 4362 is inserted into the mask packaging bag;

[0076] When the first clamping member 4361 and the second clamping member 4362 deliver the mask into the mask packaging bag, the rear-pressing sliding driving mechanism 6210 drives the rear-pressing mounting platform 6200 to move in the direction where the discharging mechanism is located;

[0077] After the first clamping piece 4361 and the second clamping piece 4362 enter the mask packaging bag, the rear pressure lifting drive mechanism 6220 works to make the rear pressure strip 6231 move toward the mask packaging bag. The rear pressure strip 6231 and the discharge conveyor belt 5220 clamp one end of the mask to prevent the mask from moving when the first clamping piece 4361 and the second clamping piece 4362 withdraw, so as to prevent the mask from slipping and affecting the subsequent heat sealing work. The avoidance groove 4363 allows the rear pressure strip 6231 to avoid the rear pressure strip 6231 and the discharge conveyor belt 5220. The material conveyor belt 5220 clamps one end of the mask; at the same time, the front pressure driving member 3433 works, the front pressure executive part moves toward the material discharging conveyor belt 5220, and the avoidance groove 4363 allows the front pressure executive part to avoid the position, so that the front pressure executive part and the material discharging conveyor belt 5220 clamp the other end of the mask, preventing the first clamping member 4361 and the second clamping member 4362 from moving the mask and the ear straps of the mask when withdrawing, so that the mask or the ear straps are exposed from the mask packaging bag, and the mask and the ear straps are prevented from slipping and affecting the subsequent heat sealing work;

[0078] Then, the horizontal driving mechanism 4230 drives the moving frame 4220 to slide in a direction away from the discharging mechanism, so that the first clamping member 4361 and the second clamping member 4362 exit the mask packaging bag and reset to standby, and at the same time, the bag opening vacuum suction cup 2520 and the bag taking suction cup 3432 stop working, and the bag supporting mechanism and the back pressing mechanism reset;

[0079] Then, the discharging drive mechanism 5230 drives the discharging conveyor belt 5220 to rotate, and the partition bar 5221 drives the masks and mask packaging bags in the product placement slot to move to the outside of the frame 100, so that the openings of the multiple mask packaging bags move between the heat sealing knife 5320 and the heat sealing seat 5330, and then the heat sealing drive mechanism 5340 drives the heat sealing knife 5320 to approach the heat sealing seat 5330 to seal the mask packaging bags;

[0080] Then, the discharging drive mechanism 5230 drives the discharging conveyor belt 5220 to rotate, and discharges the mask packaging bags containing the masks;

[0081] The above operations are repeated, and the first circulating conveyor belt 1340 and the second circulating conveyor belt 1440 perform material collection work alternately.

[0082] The mask bagging machine of this scheme has multiple bagging channels, and the various motion actuators cooperate closely with each other. At the same time, a mechanism is provided to prevent the mask from escaping from the mask packaging bag, which significantly improves the packaging efficiency and the packaging qualification rate.
