Description

Technical Field

[0001] The present invention relates to the technical field of chemical auxiliary filling, and particularly relates to a chemical auxiliary filling device with an anti-tipping structure. Background Art

[0002] Chemical auxiliaries are generally stored in a sealed manner by canning, and a filling machine is used for direct canning. The height of the tank body generally exceeds the diameter, so the balance point is relatively high. During canning, the impact force generated by the spraying of the nozzle may cause the tank body to tilt, posing a safety hazard. Therefore, it is necessary to use a tooling to fix the tank body for canning.

[0003] The currently used canning devices have the following disadvantages: 1. Disassembly and assembly require manual operation, which is cumbersome and time-consuming. It is inconvenient to quickly transport the tank body to the designated position and position it, and there is a lack of an auxiliary conveying structure to prevent tipping. 2. There is a lack of a docking structure. When directly spraying into the tank body, the chemical auxiliaries are prone to splashing. There is a lack of a docking type canning structure, which is inconvenient for automatically docking the tank body for safe canning. 3.

[0028] like Figures 1 - 9 As shown, during operation, the can body is placed on the front upper part of the main conveyor belt 109, and the can body is taken out from the rear upper part of the main conveyor belt 109, and the taking and placing operations are performed by workers in different processes; Start the drive motor 103 to drive the synchronous shaft 102 to rotate. The synchronous shaft 102 simultaneously drives two groups of vertical conveying rollers 110 to rotate, and then the two side conveyor belts 2 and the main conveyor belt 109 rotate at the same speed to convey the tank body backward. The tank body is positioned by the infrared sensor 12 and stops moving when it moves below the fixed outer buckle 10; During this period, the anti-tipping buckle 201 provides an auxiliary conveying effect and can effectively prevent the tank body from tipping over; First, use the electric cylinder 301 to push the piston member 302, squeeze the air in the piston cylinder 5. The air moves downward through the four-way pipe 4, expands the corrugated pipe 8, so that the output pipe 9 and the fixed outer buckle 10 descend, bring the docking seal ring 1003 into contact with the top of the tank body, and seal the tank body; The input end of the transfer pump 7 is connected to the source of chemical additives. Open the solenoid valve 6 connected to the transfer pump 7, and use the transfer pump 7 to extract chemical additives. Input the liquid chemical additives into the four-way pipe 4, and then the chemical additives pass through the corrugated pipe 8 and enter the output pipe 9, pushing the inner movable valve 904 downward. When the inner movable valve 904 descends, the continuously input chemical additives pass through the output channel 905 and are discharged downward, and finally input into the tank body for canning; During this period, the excess air in the tank body will pass through the space between the lower anti-splash edge 1002 and the upper anti-splash edge 902, and finally be discharged from the exhaust hole 1001; The lower anti-splash edge 1002 and the upper anti-splash edge 902 provide an anti-splash function, which can prevent the droplets generated by canning from splashing to the outside; Set the delivery volume of the transfer pump 7 through the control program, and then perform canning. After stopping the delivery of chemical additives, open the solenoid valve 6 above the four-way pipe 4, retract the electric cylinder 301, reset the piston member 302, and the outside air passes through the upper solenoid valve 6 and the four-way pipe 4 and enters the piston cylinder 5 for replenishment; Then close the upper solenoid valve 6, extend the electric cylinder 301, cooperate with the piston member 302 to squeeze the piston cylinder 5 again, generate air pressure to discharge the residual chemical additives in the corrugated pipe 8 and the output pipe 9 outward, and all can be canned into the tank body; Retract the electric cylinder 301 again to reset the piston member 302, use the negative pressure generated in the piston cylinder 5 to contract the corrugated pipe 8, raise the output pipe 9 and the fixed outer buckle 10, and make the docking seal ring 1003 separate from the tank body, then the safe canning can be completed.

[0029] Embodiment 2: On the basis of Embodiment 1, a tensioning frame 106 is fixedly arranged in the middle of the rear side of the top of the fixed base 1, and a tensioning screw 107 is arranged through the middle of the tensioning frame 106; A connecting frame 105 is fixedly arranged at the rear side of the two movable seats 104, and the tensioning screw 107 is threadedly connected with the connecting frame 105; The middle top of the front side of the tensioning frame 106 extends forward and is fixedly provided with a proximity switch 108, and the proximity switch 108 is higher than the top of the main conveyor belt 109; The length of the side conveyor belt 2 is consistent with that of the main conveyor belt 109; When the tension of the side conveyor belt 2 and the main conveyor belt 109 needs to be adjusted, the tensioning screw 107 is rotated with a wrench to drive the connecting frame 105 and the movable seat 104 to move, thereby adjusting the tension of the side conveyor belt 2 and the main conveyor belt 109.

[0030] Embodiment 3: Based on Embodiment 1, when the can body is not taken out in time from the rear side, the can body at the rearmost side will move backwards and contact the proximity switch 108. The drive motor 103 is temporarily stopped by the feedback signal of the proximity switch 108 so that the staff can take out the can body. At this time, the anti-tipping buckles 201 on both sides are still not separated, and the can body can be supported; The control program is pre-set, and the feeding stroke is also stopped when the driving motor 103 stops temporarily, and the unmoved distance is subsequently supplemented to complete the automatic feeding.

[0031] Specific usage and function of this embodiment: In the present invention, according to Figure 1 In the method, the can body is placed above and in front of the main conveyor belt 109, and the can body is taken out from above and behind the main conveyor belt 109; The drive motor 103 is started to drive the synchronous shaft 102 to rotate, and the synchronous shaft 102 drives the two sets of vertical conveying rollers 110 to rotate at the same time, so that the two sets of side conveyor belts 2 and the main conveyor belt 109 rotate at the same speed to convey the can body backwards, and the can body is positioned by the infrared sensor 12, and the can body stops moving when it moves to the bottom of the fixed outer buckle 10; the anti-dumping buckle 201 provides an auxiliary conveying effect and can prevent the can body from dumping; First, the electric cylinder 301 is used to push the piston 302 to squeeze the air in the piston tube 5. The air moves downward through the cross-tube 4, expands the bellows 8, and the output pipe 9 and the fixed outer buckle 10 are lowered. The docking sealing ring 1003 contacts the top of the tank body and closes the tank body. Open the solenoid valve 6 connected to the delivery pump 7, and use the delivery pump 7 to extract the chemical additives, input the liquid chemical additives into the four-way pipe 4, and then the chemical additives pass through the bellows 8 into the output pipe 9, pushing the inner movable valve 904 downward. When the inner movable valve 904 descends, the chemical additives that continue to be input are discharged downward through the output channel 905 and input into the tank body for canning; The excess air in the tank body will pass through the gap between the lower splash guard edge 1002 and the upper splash guard edge 902, and finally be discharged from the exhaust hole 1001; Canning is carried out by setting the delivery volume of the delivery pump 7 through the control program. After stopping the delivery, the solenoid valve 6 above the four-way pipe 4 is opened, the electric cylinder 301 is contracted, the piston member 302 is reset, air is re-pumped into the piston cylinder 5, and the outside air passes through the upper solenoid valve 6 and the four-way pipe 4 to enter the piston cylinder 5 for replenishment. Then the upper solenoid valve 6 is closed, the electric cylinder 301 is extended, and the piston member 302 is used to squeeze the piston cylinder 5 again to generate air pressure to discharge the residual chemical additives in the bellows 8 and the output pipe 9 outwards and fill them all into the tank body; Then, the electric cylinder 301 is contracted again to reset the piston member 302. The negative pressure generated in the piston cylinder 5 contracts the bellows 8, raises the output pipe 9 and the fixed outer buckle 10, and the docking sealing ring 1003 disengages from the tank body to complete the safe canning; The driving motor 103 is controlled by the program to continue working to feed the tank body to the next station, and then the above steps are repeated to carry out continuous cyclic canning; If the tank body at the rear is not taken out in time, the tank body at the rearmost side will move backward to contact the proximity switch 108. The proximity switch 108 is used to feedback a signal to temporarily stop the driving motor 103 so that the staff can take out the tank body. At this time, the anti-tipping buckles 201 on both sides are still not separated and can maintain the support for the tank body; when the driving motor 103 is temporarily stopped, the control program also stops the stroke, and the remaining distance that has not been moved is supplemented later to complete the feeding.
