[0025] like Figures 1-6 As shown, the continuous cap removal device of the automatic filling line for refrigerant small steel cylinders in this embodiment of the utility model includes a mounting base 1. A refrigerant small steel cylinder conveying mechanism 2 is provided on the rear side inside the mounting base 1, and a cap removal mechanism 5 is provided on the top of the mounting base 1. The refrigerant small steel cylinder conveying mechanism 2 is used to convey and fill the small steel cylinders, and the cap removal mechanism 5 is used to remove the protective caps for the small steel cylinders. At the same time, the protective caps are put on the top of the small steel cylinders and tightened to protect the small steel cylinders. It can also quickly install protective caps on multiple small steel cylinders.

[0026] The cap removal mechanism 5 includes an arched mounting frame 501 fixedly installed on the top of the mounting base 1. A second mounting plate 503 is provided on the inner side of the arched mounting frame 501. A first mounting plate 502 is provided at the bottom of the second mounting plate 503. A motor 508 is fixedly installed on the top of the first mounting plate 502. The output shaft of the motor 508 passes through the first mounting plate 502 and is fixedly installed on the cap removal frame 509. A movable squeezing block 510 is provided at the bottom of the cap removal frame 509. Both the movable squeezing block 510 and the cap removal frame 509 have cap removal cavities 511 inside. A rubber pad 514 is fixedly installed inside the cap removal cavity 511. The first mounting plate 502 is used to install and fix the motor 508. The motor 508, the cap-removing bracket 509, and the moving squeezing block 510 are used to pick up the protective cap of the small steel bottle and rotate it to fix the protective cap to the top of the small steel bottle. At the same time, the arrangement of multiple motors 508, cap-removing brackets 509, and moving squeezing blocks 510 can install the protective caps on multiple small steel bottles at the same time, avoiding the fact that traditional manual installation cannot meet the needs of automated filling.

[0027] The top of the arched mounting bracket 501 is provided with a guide groove 516, and a mounting block 507 is slidably connected inside the guide groove 516. The bottom of the mounting block 507 is fixedly connected to the top of the second mounting plate 503. The guide groove 516 and the mounting block 507 are used to install the second mounting plate 503, and at the same time, the movement of the second mounting plate 503 drives the motor 508, the cap-removing bracket 509 and the moving pressing block 510 to move, thereby picking up the protective cap placed on the top of the cap placement table 3.

[0028] A third mounting plate 506 is fixedly mounted on the left side of the top of the arched mounting bracket 501, and a first electric push rod 504 is fixedly mounted on the right side of the mounting block 507. The output shaft of the first electric push rod 504 passes through the mounting block 507 and is fixedly connected to the right side of the third mounting plate 506. The arrangement of the first electric push rod 504 and the third mounting plate 506 is used to drive the second mounting plate 503 and the motor 508 to move.

[0029] A second electric push rod 505 is fixedly installed on both sides of the top of the second mounting plate 503. The output end of the second electric push rod 505 passes through the second mounting plate 503 and is fixedly connected to the top of the first mounting plate 502. The second electric push rod 505 is used to drive the second mounting plate 503, motor 508, cap removal bracket 509 and moving compression block 510 to descend, thereby causing the protective cap fixed inside the cap removal bracket 509 and moving compression block 510 to descend to the top of the small steel cylinder for installation and protection with the small steel cylinder.

[0030] The inner side of the hat-removing holder 509 has two sliding grooves 515, and a slider 513 is slidably connected inside the sliding grooves 515. The bottom of the slider 513 is fixedly connected to the top of the movable pressing block 510. The connection between the movable pressing block 510 and the hat-removing holder 509 is achieved through the cooperation between the sliding grooves 515 and the slider 513.

[0031] A spring 512 is fixedly installed on one side of the slider 513, and one side of the spring 512 is fixedly connected to the inner cavity of the slide groove 515. The spring 512 compresses the slider 513, thereby pushing the moving compression block 510 to move closer to the cap holder 509. With the cooperation of the cap holder 509, the protective cap is clamped and picked up. The rubber pad 514 increases the friction on the protective cap, increasing the stability of the protective cap when it is picked up.

[0032] Side limiting plates 4 are fixedly installed on the top of the mounting base 1 and on both the front and rear sides of the refrigerant cylinder conveying mechanism 2. A cap placement table 3 is fixedly installed on the top of the mounting base 1 and on the front side of the side limiting plates 4. The side limiting plates 4 protect the moving cylinders, and the cap placement table 3 places the protective caps to be installed for easy retrieval by the cap removal mechanism 5.

[0033] In use, the protective cap to be installed is placed on top of the cap placement table 3. The refrigerant cylinder conveying mechanism 2 conveys the filled cylinder. During the conveying process, the first electric push rod 504 drives the mounting block 507 to move, which in turn moves the second mounting plate 503, the first mounting plate 502, the motor 508, the cap removal frame 509, and the moving squeezing block 510. After the cap removal frame 509 and the moving squeezing block 510 move to the top of the cap placement table 3, the second electric push rod 505 pushes the first mounting plate 502 to descend. The descent of the first mounting plate 502 causes the cap removal frame 509 and the moving squeezing block 510 to descend, allowing the protective cap to be inserted into the cap removal cavity 511. The protective cap is then fixed in place by the rubber pad 514. After the protective cap is removed, the second electric push rod 505 pushes the first mounting plate 502 to descend. The electric push rod 505 lifts the first mounting plate 502, motor 508, cap removal bracket 509, and movable pressing block 510. At the same time, the first electric push rod 504 drives the mounting block 507 to move, which in turn moves the second mounting plate 503, the first mounting plate 502, motor 508, cap removal bracket 509, and movable pressing block 510 to the top of the refrigerant small cylinder conveying mechanism 2. Then, the cap removal bracket 509 and movable pressing block 510, along with the protective cap, are lowered. After lowering, the protective cap is fitted onto the top of the small cylinder. The motor 508 drives the cap removal bracket 509, movable pressing block 510, and protective cap to rotate, thereby making the protective cap threadedly connected to the top of the small cylinder. The second electric push rod 505 pulls the cap removal bracket 509 and movable pressing block 510 to lift, thereby separating them from the protective cap, thus realizing the installation of the protective cap.

[0034] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
