Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic packaging, and in particular relates to a double-station bag opening structure. Background Art

[0002] In the production of cosmetics, packaging bags are needed to package the finished cosmetics. When packaging, a bag opening structure is needed. The finished products are fed into the packaging bags after the bags are opened for packaging. The traditional bag opening mechanism is a single-channel one.

[0003] The single-channel bag opening mechanism is a single-station bag opening packaging, which can only process one product at a time. For cosmetics that need to be produced in large quantities, this working method will lead to low production efficiency, thereby extending the time of the entire production process. If the working speed of the production line changes, such as speeding up or slowing down, the packaging speed of the single-channel bag opening mechanism may not be able to adapt to this change, thus affecting the efficiency of the entire production line. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the utility model proposes a double-station bag opening structure.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double-station bag opening structure comprises a base and an upper support plate. The four corners of the top of the base are fixedly connected to the upper support plate through four vertical shafts. The ends of the piston rods of two bidirectional cylinders provided on the base are respectively fixedly connected to spur teeth, which mesh with the gears on the rotating shaft. The top end of the rotating shaft passes through the upper support plate and is fixedly connected to a fixed bag opening mounting seat on the upper support plate. The fixed bag opening mounting seat is connected to the bag opening plate through an adjusting plate.

[0007] The bidirectional cylinder action drives the spur teeth to mesh with the gears, and then drives the two shafts to rotate in opposite directions, thereby driving the fixed bag opening mounting seat, the adjustment plate and the bag opening plate to expand outward or retract inward to open the packaging bag or put the bag opening plate in the initial state.

[0008] Preferably, two bag opening plates for opening the packaging bag are rotatably connected to the ends of the aisle sheet metals, respectively, and the two aisle sheet metals form a passage leading to the opening between the two bag opening plates.

[0009] Preferably, a suction cup mounting bracket is fixedly provided at the bottom of the upper support plate, on which a suction cup is installed, which is embedded in the surface of the upper support plate and is used to suck and position the packaging bag when the bag opening plate opens the packaging bag. The suction cup is located in the opening between the two bag opening plates.

[0010] The suction cup can hold the packaging bag during the bag opening process to ensure that the packaging bag does not move during the bag opening process, thereby improving the accuracy of bag opening.

[0011] Preferably, bearing seats which rotate in cooperation with the rotating shaft are fixedly provided on the base and the upper supporting plate respectively.

[0012] Preferably, a buffer bracket for mounting a buffer is provided on the top of the base, and the buffer is used to buffer and limit the end of the piston rod extending from the bidirectional cylinder.

[0013] Preferably, a proximity switch bracket for installing a proximity switch is provided on the top of the base, and the proximity switch is used to monitor the recovery status of the two piston rods on the bidirectional cylinder.

[0014] The proximity switch can monitor the recovery status of the two piston rods on the bidirectional cylinder in real time, ensuring that the cylinder stops moving at the appropriate time and improving the accuracy of the operation.

[0015] Preferably, one of the two bidirectional cylinders is fixed on the top of the base, and the other is fixed on the raised platform on the top of the base, so as to realize the staggered arrangement of two sets of gears, spur gears and bidirectional cylinders in the same space, thereby improving the space utilization.

[0016] Compared with the prior art, the technical effects and advantages of the utility model are:

[0017] The double-station bag opening structure starts the double-station bag opening structure, compressed air is input into the two-way cylinder, and the spur teeth at the end of the piston rod of the two-way cylinder mesh with the gear on the rotating shaft. When the piston rod of the two-way cylinder moves left and right, the spur teeth drive the rotating shaft to rotate, and the two rotating shafts mesh with gears and rotate in opposite directions. The top of the rotating shaft is connected to a fixed bag opening mounting seat, which is connected to the bag opening plate through an adjustment plate. The rotation of the rotating shaft drives the bag opening mounting seat, the adjustment plate and the bag opening plate to expand outward or retract inward, thereby realizing automatic bag opening of the packaging bag. When the bag opening plate expands, the packaging bag is opened with the help of the suction cup to expose the bag opening, and the bag opening mechanism delivers the product into the opened packaging bag. After the bag opening is completed, the bag opening plate is retracted to prepare for the next packaging cycle.

[0018] The double-station bag opening structure can perform two packaging cycles at the same time, which means that two products can be packaged in a single working cycle, thereby significantly improving production efficiency. Since two packaging cycles can be performed continuously, the double-station bag opening structure can perform continuous operations without stopping the entire production line, reducing downtime and improving the overall production line efficiency.

DETAILED DESCRIPTION

[0023] 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.

[0024] The following is combined with Figure 1-3 To further explain this application in detail,

[0025] The embodiment of the present application discloses a double-station bag opening structure, comprising a base 1 and an upper support plate 2, wherein the four corners of the top of the base 1 are fixedly connected to the upper support plate 2 via four vertical shafts 3;

[0026] The piston rod ends of two bidirectional cylinders 4 provided on the base 1 are respectively fixedly connected to spur gears 5, which mesh with gears 7 on the rotating shaft 6. The top end of the rotating shaft 6 passes through the upper support plate 2 and is fixedly connected to a fixed bag opening mounting seat 8 on the upper support plate 2. The fixed bag opening mounting seat 8 is connected to the bag opening plate 10 through an adjusting plate 9.

[0027] The action of the bidirectional cylinder 4 drives the spur teeth 5 to mesh with the gear 7, thereby driving the two rotating shafts 6 to rotate in opposite directions, thereby driving the fixed bag opening mounting seat 8, the adjustment plate 9 and the bag opening plate 10 to expand outward or retract inward to open the packaging bag or put the bag opening plate 10 in the initial state.

[0028] The automatic bag opening process of the packaging bag is realized through the compound movement of pneumatic drive and the meshing of mechanical gears 7. The bidirectional cylinder 4 in the mechanism is controlled by compressed air to make the spur teeth 5 at the end of the piston rod move left and right. The spur teeth 5 mesh with the gears 7 on the rotating shaft 6, so that when the cylinder piston moves left and right, the rotating shaft 6 can be driven to rotate. The two rotating shafts 6 are meshed through the above-mentioned gears 7 and are driven by the cylinders to rotate in opposite directions. The top of the rotating shaft 6 is connected to a fixed bag opening mounting seat 8, which is connected to the bag opening plate 10 through an adjustment plate 9. Therefore, when the rotating shaft 6 rotates, the bag opening mounting seat, the adjustment plate 9 and the bag opening plate 10 will expand outward or close inward.

[0029] When the bag opening plate 10 is expanded, it will cooperate with the suction cup 15 to open the packaging bag and expose the bag opening. At the same time, the bag opening mechanism delivers the product into the opened packaging bag. After the bag opening is completed, the bag opening plate 10 can be folded to carry out the next packaging cycle.

[0030] The double-station bag opening structure can perform two packaging cycles at the same time, which means that two products can be packaged in a single working cycle, which significantly improves production efficiency. Since two packaging cycles can be performed continuously, the double-station bag opening structure can perform continuous operations without stopping the entire production line, reducing downtime and improving overall production line efficiency. The double-station bag opening structure is designed to be more modular and automated, which makes it faster and more convenient when changing the type of packaging bag or adjusting the settings. The double-station bag opening structure realizes the bag opening operation through automated components (such as bidirectional cylinders and gear meshing systems), reducing the need for manual bag opening, reducing labor intensity, and reducing the possibility of human error.

[0031] The two bag opening plates 10 for opening the packaging bags are rotatably connected to the ends of the aisle sheet metal 11 respectively, and the two aisle sheet metals 11 form a channel 13 leading to the opening 12 between the two bag opening plates 10; connecting the bag opening plates 10 by the aisle sheet metal 11 can simplify the mechanism structure, reduce the number of components, and improve the stability and reliability of the overall mechanism.

[0032] The two bag opening plates 10 are both made of plastic to increase softness and prevent the bag from bursting.

[0033] A suction cup mounting bracket 14 is fixedly provided at the bottom of the upper support plate 2, and a suction cup 15 is installed on the suction cup mounting bracket 14, which is embedded in the surface of the upper support plate 2 and is used to suck and position the packaging bag when the bag opening plate 10 is opening the packaging bag. The suction cup 15 is located in the opening 12 between the two bag opening plates 10. The suction cup 15 can suck the packaging bag during the bag opening process to ensure that the packaging bag does not move during the bag opening process, thereby improving the accuracy of bag opening. When the bag opening plate 10 opens the packaging bag, the suction cup 15 can prevent the packaging bag from sliding due to material friction or airflow, thereby ensuring the stability of the operation.

[0034] The base 1 and the upper support plate 2 are respectively fixed with bearing seats 16 that rotate in cooperation with the rotating shaft 6;

[0035] A buffer bracket 18 for mounting a buffer 17 is provided on the top of the base 1. The buffer 17 is used to buffer and limit the end of the piston rod extending from the two-way cylinder 4. The buffer 17 can buffer and limit the end of the piston rod extending from the two-way cylinder 4 to prevent the piston rod from damaging the cylinder or other components due to excessive extension. During the movement of the piston rod, the buffer 17 can reduce the impact force caused by sudden stop or collision, reduce the risk of equipment failure, and make the movement of the piston rod smoother, reduce vibration and noise, and improve the overall comfort and stability of operation.

[0036] Adding the buffer 17 further reduces the bag breakage rate.

[0037] The top of the base 1 is provided with a proximity switch bracket 19 for mounting a proximity switch, and the proximity switch is used to monitor the recovery status of the two piston rods on the bidirectional cylinder 4. The proximity switch can monitor the recovery status of the two piston rods on the bidirectional cylinder 4 in real time, ensure that the cylinder stops moving at the appropriate time, and improve the accuracy of the operation. The proximity switch provides electrical signal feedback and can be used in an automated control system to achieve precise control and adjustment of the cylinder movement. By monitoring the position of the piston rod, the proximity switch can sound an alarm or automatically stop the machine when the piston rod approaches a dangerous area to prevent accidental injuries or equipment damage. Since the proximity switch can automatically monitor and feedback information, it can reduce the need for manual detection and improve production efficiency.

[0038] One of the two bidirectional cylinders 4 is fixed on the top of the base 1, and the other is fixed on the raised platform 20 on the top of the base 1, so that the two sets of gears 7, spur gears 5 and bidirectional cylinders 4 are staggered in the same space, and the above can be assembled in a limited space, thereby improving space utilization. Since the positions of the two sets of components are staggered, the assembly process is more convenient and the possibility of mutual interference and collision is reduced. This design makes the entire mechanism compact, reduces unnecessary space waste, and is conducive to overall aesthetics and equipment integration.

[0039] The double-station bag opening structure realizes automatic bag opening of the packaging bag through the compound movement of pneumatic drive and meshing of mechanical gear 7. The bidirectional cylinder 4 drives the spur gear 5 to rotate, and transmits power through the meshing of gear 7 to make the bag opening plate 10 move, cooperate with the suction cup 15 to position and open the bag mechanism, and complete the packaging process. Automatic bag opening reduces manual operation, improves production speed, reduces the need for manual bag opening, reduces labor costs, and the automation process reduces the possibility of human error and ensures product quality.

[0040] It adopts a mechanical structure and cooperates with pneumatic drive, which has stable operation, low failure rate, reasonable structural design, easy maintenance, and reduced maintenance costs. The automated process ensures the accuracy of bag opening and improves product quality. In the long run, double-station automatic bag opening can reduce labor costs, improve production efficiency, and thus reduce overall production costs.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
