Description

Technical Field

[0001] The present invention relates to aerosol packaging equipment, in particular to a full-automatic actuator assembly machine. Background Art

[0002] Aerosols are products that contain a material and a suitable propellant enclosed in a pressure-resistant container with a specialized valve. During use, the pressure from the propellant within the container sprays the contents into a fine mist, foam, or other form. An actuator, mounted on the valve core, opens the aerosol valve.

[0003] The aerosol actuator assembly process generally follows the completion of material filling, valve installation, valve sealing, propellant filling (inflation), weighing inspection, and water bath sealing testing. The randomly stacked actuators are sorted and orderly output and transported. The aerosol can and actuator are then fed synchronously, and finally the actuator is assembled on the aerosol valve core by pressing or striking.

[0004] In the existing patent literature, for example, an article entitled "Star Wheel Assembly Device for Automatic Pressing Actuator Machine" published on September 26, 2012, with application number 2012101783993, includes a main shaft body, an upper star wheel assembly, a lower star wheel, a guardrail and a slide plate assembly. The main shaft body is fixed on the workbench, the middle flange of the main shaft is connected to the lower star wheel, and the lower end of the main shaft is connected to the indexing mechanism; the upper star wheel assembly is connected to the upper and lower flange surfaces of the star wheel seat by bolts respectively, and a tightening sleeve is used to realize the concentric fixed connection between the upper star wheel assembly and the main shaft; the guardrail and the slide plate assembly are fixed on the workbench.

[0005] The existing automatic actuator press machine has several drawbacks: The step-by-step feed method using an indexing mechanism results in a production efficiency of less than 60 cans per minute. The method uses a cylinder-connected pressure head to directly strike the actuator. Due to the high impact force and the time required for the cylinder to reverse and lift, the pressure inside the aerosol can is high. Once the impact pressure exceeds the pressure required to open the valve core, the propellant and material will be ejected from the valve core. Even with the best imported high-speed reversing cylinder, it is difficult to prevent the propellant and material from being ejected from the valve core. This not only contaminates the equipment and the aerosol body, but some of the material may clog the actuator's injection path after solidification, affecting product quality. More importantly, propellant is a flammable and explosive gas, and long-term accumulation can pose safety risks. Aerosol manufacturers have to add protective measures such as induced draft fans and flammable and explosive gas detectors. Once the detector alarms, the entire production line must be stopped immediately, disrupting normal production order.

[0006] The switching time for multiple varieties is very long, especially in responding to the adjustment time of aerosol cans at different heights. It is manifested as follows: first, the tension sleeve must be loosened and moved up and down to adjust the height of the star wheel to match the height of the corresponding aerosol can, and the center of any equally divided semicircular groove of the actuator star wheel must be aligned with the center of the fixed pressure head; then the height of the "actuator guide device of the automatic actuator press" must be adjusted to match the height of the aerosol can. Finally, the height of the vibrating material sorting device must be adjusted to match the inlet height of the "actuator guide device of the automatic actuator press", which is time-consuming and labor-intensive.

The structure is compact and sophisticated, which not only improves the space utilization of the equipment, but also greatly improves the production efficiency.

Aerosol can A is provided with an aerosol can slide 500 on the workbench; the aerosol can slide 500 includes an upper can slide 510, a middle slide 520, and a lower can slide 530 connected in sequence; aerosol can A enters the upper can slide 510 and slides, and aerosol can A gradually rises vertically under the limit of the tank body star wheel 122 and the outer guardrail. The aerosol can valve cup gradually enters the valve cup star wheel 132 guide groove from bottom to top, and the valve spool gradually passes through the valve spool arc groove 211 on the positioning base plate 210.

[0158] Reference Figure 12 Status shown:

[0159] 1. The bottom of aerosol can A slides on the middle slide rail 520. The valve cup of the aerosol can has completely entered the guide groove of the valve cup star wheel 132. When the actuator B just passes over the actuator arc groove 212 on the positioning base plate 210, the actuator B and aerosol can A reach the starting point of assembly.

[0160] 2. The rotating assembly 100 rotates, and the arc cam of the striking assembly 300 is acted upon by the striking follower 1431 disposed on the outside of the pressure head guide plate 143, thereby lifting the entire swing plate 320. The compression spring contracts, accumulating energy. When the arc cam separates from the striking follower 1431, the striking block 390 reaches its highest point and is located above the spring pressure head 150.

[0161] Reference Figure 13 Status shown:

[0162] 1. The arc-shaped cam of the striking assembly 300 separates from the striking follower 1431. The swing plate 320 accelerates downward under the action of gravity and compression spring 1 370. The striking block 390 strikes the top of the spring pressure head 150, causing the spring pressure head 150 to move downward, driving the actuator B downward. When the actuator B begins to contact and assemble with the valve core, the guide groove of the actuator star wheel 141 and the actuator guide plate 230 still maintain the circumferential positioning of the actuator B.

[0163] 2. As the rotating assembly 100 rotates, before the striking block 390 reaches the lower starting point, the bottom of the buffer body provided at the rear of the swing plate 320 contacts the shaft seat plate 310, and buffering begins. At this time, the actuator B has completely entered the valve core, and the guide groove of the actuator star wheel 141 and the actuator guide plate 230 have just separated from the actuator B, ensuring the accuracy of assembly. As the striking block 390 separates from the spring pressure head 150, the front of the arc cam of the striking assembly 300 is still a certain distance away from the next striking follower 1431.

[0164] 3. The striking stroke is much greater than the assembly stroke of actuator B and the valve core, which will inevitably open the actuator valve and eject the propellant and material. During the actual striking assembly process, actuator B and the valve core are in a transitional fit, and there is a certain amount of resistance during the assembly process. The compression spring 2 153 in the sliding cavity of the spring pressure head 150 contracts, and the actual force acting on the pressure head 152 is the resistance of the compression spring 2 153 plus the inertia of the spring pressure head 150. To prevent the ejection of propellant and material, the actual combined force acting on the pressure head 152 is generally set to be slightly less than the force required to open the valve core. Furthermore, the contraction stroke of the compression spring 2 153 plus the assembly stroke of actuator B and the valve core must be greater than the stroke of the striking block 390 descending to the buffer after contact with the spring pressure head 150. The assembly of actuator B and the valve core is always in an elastic state, effectively preventing the ejection of propellant and material.

[0165] Reference Figure 14 Status shown:

[0166] 1. The spring pressing head 150 is separated from the striking block 390 and, under the action of gravity, the spring pressing head 150 falls onto the pressing head limiting plate 142;

[0167] 2. As the rotating assembly 100 rotates, the actuator B and the aerosol can assembly that have been assembled after being struck gradually descend vertically under the limit of the can body star wheel 122 and the outer guardrail. The assembled actuator B and the aerosol can assembly are completely separated from the upper and middle components 130 of the rotating assembly 100 (excluding the can body star wheel 122), ready to flow out of the device and enter the conveyor line 400.

[0171] Reference Figure 23 As described above, after the actuator installation process, the aerosol can A10 enters the conveyor line 400 through the guide seat 410. During the horizontal transmission process of the conveyor line 400, the can rejection guide plate B110 pushes the aerosol can A10 toward the can rejection port B120. The aerosol can A10 with the actuator installed intact is blocked by the guide rod B130 and continues to move to the right. The aerosol can A10 with the actuator installed unsuccessfully is unable to be blocked by the guide rod B130 due to the missing top actuator, that is, the aerosol can A10 without the actuator installed falls from the can rejection port B120.

[0172] The can rejection guide plate B110 is further defined as being plate-shaped and having an arc-shaped pusher portion B111 extending toward the center of the conveyor line 400.

The spline shaft 110 passes upward through the inner spline sleeve 121 rotatably arranged on the workbench C100, and the top of the spline sleeve is fixedly connected to the actuator star wheel 322; the inner spline sleeve 121 is rotatably connected to the spline bearing seat C520, and the spline bearing seat C520 is fixedly connected to the workbench C100, and the upper part of the inner spline sleeve 121 is fixedly connected to the tank body star wheel 122; the tank body star wheel 122 is provided with a rotating groove adapted to the aerosol tank A, and the aerosol tank A enters the rotating groove and is rotated by the tank body star wheel 122 to transfer the aerosol tank A to the corresponding workstation.

[0194] And a synchronous transmission mechanism, the guide shaft one, guide shaft two and spline shaft are synchronously adjusted up and down on the workbench along with the lifting platform through the synchronous transmission mechanism.

[0195] It is further defined that the synchronous transmission mechanism includes:
