[0014] As an optimal technical solution for a chemical liquid filling gun head mechanism, a remote control switch is installed in the hollow cylinder.

[0015] Beneficial effects of the present invention: 1. The telescopic distance of the inner arm of the chemical liquid filling gun head mechanism is greater than that of the pillar. The inner arm will touch the peripheral wall of the filling valve before the pillar. The inner arm will be moved deep into the outer shell. At this time, the filling material in the outer shell will be acted into the hollow cylinder, and the pillar will be acted in the opposite direction, ensuring the stability of the filling valve under different radial directions when in use; 2. When the liquid filling gun head mechanism of the chemical liquid passes through the filling valve to circulate liquid or the overall position changes, the filling valve and the outer bearing module will have a shaking relationship. At this time, the filling valve and the limit pad are not fully and evenly stressed. At this time, the force point on the limit pad changes. Under the action of the replenishment module, according to the amplitude of the shaking, the extension pad acts on the storage rack with different forces, and the corresponding amount of filler can be applied to the hollow cylinder through the transmission channel, so that the filler in the hollow cylinder and the outer shell cylinder increases. Therefore, the support column and the inner arm are further moved closer to the position of the filling valve, so as to adjust the state of the filling valve and restore it to a stable state; 3. The chemical liquid filling gun head mechanism is operated by the rubber-type concave hole. When the limit pad acts on the filling valve, the air in the rubber-type concave hole is squeezed out by the filling valve to form a low-pressure area. Due to the existence of external atmospheric pressure, the air pressure between the rubber-type concave hole and the filling valve is lower than the external air pressure, forming a pressure difference to ensure the stable performance of the filling valve after placement; 4. The chemical liquid filling gun head mechanism can adjust the corresponding position of the bifurcated part through the configuration of the linkage ring seat and the linkage disk, and the axial position of the filling valve does not change, and will not affect the stability of the filling valve; 5. The chemical liquid filling gun head mechanism uses a horizontal cylinder and a vertical cylinder. The filling valve can move horizontally and vertically within a certain range. Through automatic control by PLC and photoelectric sensors, it can be positioned to a specified position. The filling valve can be automatically opened and closed, providing filling flexibility.

[0031] Example Reference Figure 1 and 2 A chemical liquid filling gun head mechanism, comprising: a carrier platform 100, a filling valve 300 and a drip leakage tray 500; a transverse cylinder 101 is arranged on the carrier platform 100, a carrier platform 200 is telescopically movable on the transverse cylinder 101, a longitudinal cylinder 101 and a longitudinal cylinder 202 are parallelly assembled on the carrier platform 200, a carrier platform 3 203 is telescopically movable on the longitudinal cylinder 202, a nitrogen replacement cylinder 400 is arranged on the moving part of the longitudinal cylinder 101, and the configuration of the nitrogen replacement cylinder 400 can be used to replace the barrel with nitrogen before filling. The air inside is replaced with N2 to ensure the cleanliness level inside the barrel. The dripping and leaking tray 500 and the carrier platform 1 100 are placed at designated positions. The excess liquid of the filling valve 300 can be collected and recycled uniformly, and at the same time, the dripping liquid will not pollute the outside. An outer bearing module 600 is installed on the carrier platform 3 203, and an inner bearing module 601 is installed on the inner edge of the outer bearing module 600. The filling valve 300 is arranged in the outer bearing module 600, wherein the inner bearing module 601 surrounds the outer periphery of the filling valve 300, and a fork 301 is provided at the side of the filling valve 300. refer to Figure 3 , 4, 6, 8 and 9, the inner bearing module 601 includes a hollow cylinder 800, an outer shell cylinder 802 and a limit pad 804, a number of telescopic members 805 are arranged on the inner edge of the bearing ring seat 701, the movable part of the telescopic member 805 is docked with the hollow cylinder 800, and the moving part of the hollow cylinder 800 is telescopically docked with the support column 801, wherein the outer periphery of the support column 801 extending into the hollow cylinder 800 is made of rubber, and the outer shell cylinder 802 is distributed at equal angles on the outer periphery of the hollow cylinder 800, and the outer shell cylinder 802 is The outer shell 802 is curved, and an inner arm 803 is telescopically movable. The shape of the inner arm 803 matches the shape of the outer shell 802. The limit pad 804 is connected to the end of the inner arm 803 extending out of the outer shell 802. The back of the limit pad 804 is connected to the support column 801. The side of the limit pad 804 facing the filling valve 300 is flexible, which is convenient for dealing with the restriction effect of the placement of the filling valve 300. The side of the limit pad 804 facing the hollow cylinder 800 has a certain toughness to play a bearing effect. When the telescopic distance of the inner arm 803 is greater than that of the support column 801, the inner arm 803 will touch the peripheral wall of the filling valve 300 before the support column 801, and the inner arm 803 will be moved deep into the outer shell 802. At this time, the filling material in the outer shell 802 will be applied to the hollow cylinder 800, wherein the filling material is liquid, and the support column 801 will be applied in the reverse direction. The support column 801 and the inner arm 803 are widely distributed, thereby ensuring the stability of the filling valve 300 during use and alleviating shaking. Under the action of the telescopic member 805, the limit pad 804 telescopes and acts on the filling valve 300. Under the action of the flexible surface of the limit pad 804, the limit pad 804 and the filling valve 300 can be effectively controlled to achieve the best limiting effect, thereby preventing damage to the surface of the filling valve 300. When the filling valve 300 is replaced, it is only necessary to control the retractable member 805 to retract, and under the action of the carrying arm 602, the inner arm 803 and the limit pad 804 will gradually return to their original positions; Reference Figure 2 , 3 5, the outer bearing module 600 includes a bearing frame 700, a bearing ring seat 701 and a linkage ring seat 702, the bearing frame 700 is assembled on 1, the bearing ring seat 701 is arranged on the inner edge of the bearing frame 700, the linkage ring seat 702 is hingedly connected to the inner edge of the bearing ring seat 701, the outer periphery of the linkage ring seat 702 is milled with a continuous tooth groove pattern, the side of the bearing ring seat 701 away from the bearing frame 700 is reserved with a slot, the outer edge of the bearing ring seat 701 is equipped with a motor 703, the moving part of the motor 703 is equipped with a linkage disk 704, the outer periphery of the linkage disk 704 is milled with a continuous tooth groove pattern, one side of the linkage disk 704 is in the bearing ring seat 701, and the linkage disk 704 is engaged with the linkage ring seat 702; In the case of application of the filling valve 300, when the fork portion 301 on the filling valve 300 needs to be adjusted in position, the linkage disk 704 can drive the linkage ring seat 702 to rotate under the action of the motor 703, and the position of the filling valve 300 will change synchronously, so as to perform better filling work; Reference Figure 6 , 8 9, a bearing arm 602 is disposed between the support column 801 and the outer shell tube 802, and the bearing arm 602 is curved; The outer shell tube 802 is hollow. With the cooperation of the carrying arm 602, the carrying arm 602 plays a bearing role for the outer shell tube 802, ensuring the stability of the filling valve 300 in the limit pad 804, and preventing the filling valve 300 from having too much control force. Under the shape characteristics of the carrying arm 602, the telescopic range of the support column 801 can be effectively controlled to prevent the movement range of the support column 801 from being too large, thereby improving the overall service life and ensuring that the limit pad 804 can ensure balance when acting on the filling valve 300; Reference Figure 6 and 7 , a supply module 603 is arranged on the inner edge of the bearing ring seat 701 near the linkage ring seat 702, and the supply module 603 includes a storage rack 900, an extension pad 901 and a transmission channel 902; the storage rack 900 is an integral type, the storage rack 900 is arranged on the inner edge of the bearing ring seat 701, the extension pad 901 is arranged on the inner edge of the storage rack 900, and the two ends of the transmission channel 902 are respectively connected to the storage rack 900 and the edge of the hollow cylinder 800, under the action of the transmission channel 902, the storage rack 900 and the hollow cylinder 800 are in a communicating relationship; The storage rack 900 installed at the inner edge of the bearing ring seat 701 has an extension pad 901 thereon. Figure 6 Position, mainly used for filling valves 300 with a larger diameter range. This design is mainly used for top radial filling valves 300; The storage rack 900 is multi-stage, and the storage rack 900 is docked with the side of the hollow cylinder 800. The multi-stage storage racks 900 are docked and communicated with each other through a soft channel 904. The storage rack 900 is guidedly docked with the inner edge of the bearing ring seat 701 through a guide member 903. The storage rack 900 installed at the side of the hollow cylinder 800 has an extension pad 901 thereon. Figure 7 The inner edge position of the limit pad 804 in the state corresponds to that of the limit pad 804, which is mainly used for the filling valve 300 within the normal diameter range and is widely used during use; When liquid flows through the filling valve 300, or when the filling valve 300 is in a process of changing its position as a whole, there will be a shaking relationship between the filling valve 300 and the outer bearing module 600. At this time, the filling valve 300 and the limit pad 804 are not fully and evenly stressed. At this time, the stress point on the limit pad 804 changes. Under the action of the replenishment module 603, according to the amplitude of the shaking, the extension pad 901 acts on the storage rack 900 with different forces, and can act on the corresponding amount of filler into the hollow cylinder 800 through the transmission channel 902, so that the filler in the hollow cylinder 800 and the outer shell cylinder 802 increases. Therefore, the support column 801 and the inner arm 803 are further moved closer to the position of the filling valve 300, so as to adjust the state of the filling valve 300 and restore it to a stable state. This adjustment effect is based on the shaking amplitude of the filling valve 300, that is, the larger the shaking amplitude of the filling valve 300, the greater the adjustment effect, so as to ensure the stable effect of the filling valve 300 when working. Under the action of the storage rack 900, a number of hollow cylinders 800 are interconnected. When the filling valve 300 shakes in one direction, the number of hollow cylinders 800 are interconnected, and the shaking in this direction can be applied to the corresponding limit pads 804 for mutual transmission, so as to ensure that the limit pads 804 in the remaining directions can supplement the force of the filling valve 300 after being acted upon by the support pillars 801 thereon, thereby ensuring the stability of the filling valve 300 during use. Reference Figure 8 and 9 A groove 604 is reserved on the inner edge of the limit pad 804, and a rubber-type concave hole 605 is milled on the inner edge of the groove 604; Under the action of the rubber-type concave hole 605, when the limit pad 804 acts on the filling valve 300, the air in the rubber-type concave hole 605 is squeezed out by the filling valve 300 to form a low-pressure area. Due to the existence of external atmospheric pressure, the air pressure between the rubber-type concave hole 605 and the filling valve 300 is lower than the external air pressure, forming a pressure difference to ensure the stable performance of the filling valve 300 after placement; Reference Fig. 9 , a remote control switch 606 is installed in the hollow cylinder 800; When the remote control switch 606 is not enabled, it is used to initially limit the filling valve 300, so that the telescopic member 805 and the hollow cylinder 800 can find the best force, wherein the remote control switch 606 is electrically controlled; When the remote switch 606 is activated, after the filling valve 300 is initially placed, it is used for overall movement or when liquid flows inside the filling valve 300 to ensure that the storage rack 900 is connected to the hollow cylinder 800 through the transmission channel 902.

[0032] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.
