Description

Technical Field

[0001] The utility model relates to a perfusion technology, in particular to a perfusion machine. Background Art

[0002] The existing random paint spraying technology is to pour the paint into a compressed air tank. When in use, the pressure of the compressed air is used to spray the paint in the compressed air tank in a mist form so as to evenly spray the paint on the surface of the object. The existing technology of pouring is to manually squeeze the paint pre-injected into the piston cylinder into the compressed air tank through a piston extruder. This pouring technology has low efficiency and large errors in the pouring amount. Summary of the invention

[0003] The invention aims to provide a filling machine which has high filling efficiency, saves manpower during filling, and has accurate filling amount and small error.

[0004] The utility model is implemented in this way, including a conveying rack, a gas tank positioning mechanism arranged at the conveying rack, and a filling mechanism arranged above the gas tank positioning mechanism, the filling mechanism includes a funnel-shaped container, a cylinder arranged at the bottom outlet of the funnel-shaped container, and a piston arranged in the cylinder and driven by a power mechanism, the upper port of the cylinder is open and connected to the bottom outlet of the funnel-shaped container, the bottom of the cylinder is provided with a perforation, the perforation is provided with a sealing ring, the size of the hole of the sealing ring matches the ejection pipe at the top end of the gas tank, and a gas tank lifting mechanism is provided on the conveying rack at the gas tank positioning position.

[0005] During operation, the conveyor frame conveys the gas cylinder to the filling location. After the gas cylinder positioning mechanism positions the gas cylinder, the gas cylinder lifting mechanism is activated to lift the gas cylinder toward the perforation at the bottom of the cylinder. The ejection pipe at the top of the gas cylinder is inserted into the sealing ring at the perforation and connected with the cylinder. The piston moves to enter the cylinder from the top of the cylinder and presses the fluid in the cylinder into the gas cylinder through the ejection pipe. Since the piston enters the cylinder from the top of the cylinder, the flow in the funnel-shaped container will fill the cylinder first before the piston enters the cylinder; before the piston enters the cylinder, the fluid outside the cylinder will be displaced until the piston enters the cylinder. After the piston enters the cylinder, the flow volume in the cylinder will not change. In this way, the flow volume of each injection is basically the same, ensuring that the injection volume is accurate and the error is small. The use of a conveyor frame and a piston driven by a power mechanism set in the cylinder has high injection efficiency and saves manpower during injection.

[0006] Preferably, the gas tank positioning mechanism comprises a vertical slot arranged at the pouring location and a permanent magnet arranged in the vertical slot. When working, the gas tank made of ordinary iron with magnetic conductivity is transported to the pouring location, and under the action of the permanent magnet, the gas tank is adsorbed at the vertical slot, and under the positioning action of the vertical slot, the gas tank is accurately positioned.

[0007] Preferably, the gas tank lifting mechanism comprises a cylinder arranged under the conveying frame, a support plate driven by the cylinder to move up and down, a hook connected to the support plate, and the height of the hook from the support plate matches the height of the gas tank. During operation, the gas tank enters the support plate, and at the same time, the upper end surface of the gas tank enters the action range of the hook, and the filling of the fluid is completed. The support plate is reset under the drive of the cylinder, and at the same time, the hook hooks the upper end surface of the gas tank, so that the gas pipe also descends with the descent of the support plate, so that the nozzle of the gas pipe is separated from the sealing ring at the bottom of the cylinder.

[0008] Preferably, a gas tank pushing mechanism is provided on the back of the positioned gas tank at the gas tank positioning position, and the gas tank that has been filled and reset is pushed out of the gas tank positioning position by the gas tank pushing mechanism so that the next gas tank to be filled can enter.

[0009] Preferably, a capping and placing mechanism is provided, and the capping and placing mechanism includes a power capping mechanism provided at the gas tank ready to enter the positioning position, a conveyor belt with the inlet end located next to the power capping mechanism, a power capping mechanism and a power nozzle releasing mechanism located at the outlet end of the conveyor belt, and a nozzle conveyor belt provided next to the power nozzle releasing mechanism. During operation, the gas tank with the cap moves to the gas tank ready to enter the positioning position, the power capping mechanism is activated, and the cap is taken from the upper end of the gas tank and sent to the conveyor belt, and then sent by the conveyor belt to the position where the gas tank is pushed out after the filling, after the gas tank is filled with fluid and pushed out of the gas tank positioning position, the power nozzle releasing mechanism is activated first, and the nozzle is taken out from the nozzle conveyor belt and placed on the nozzle of the gas tank, and then the power capping mechanism is used to take the cap from the conveyor belt and put the cap back on the upper port of the gas tank.

[0010] The full process of automatic filling can be achieved by adopting a cap pick-and-place mechanism, which greatly improves the efficiency of filling.

[0018] The utility model filling machine is now described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1 , 2 As shown in Figures 3 and 4, the filling machine of the utility model comprises a gas cylinder storage and introduction platform 1, a conveying rack 2, a gas cylinder positioning mechanism 3 arranged at the conveying rack 2, and a filling mechanism 4 arranged above the gas cylinder positioning mechanism 3. The filling mechanism 4 comprises a funnel-shaped container 401, a cylinder 402 arranged at the bottom outlet of the funnel-shaped container 401, and a piston 404 arranged in the cylinder 402 and driven by a power mechanism 403 (cylinder). The upper port of the cylinder 402 is open and connected to the bottom outlet of the funnel-shaped container 401. A through hole 405 is arranged at the bottom of the cylinder 402, and a sealing ring 406 is arranged on the through hole 405. The size of the hole of the sealing ring 406 matches the ejection pipe A1 at the top end of the gas cylinder A. A gas cylinder lifting mechanism 5 is arranged on the conveying rack 2 at the gas cylinder positioning position B.

[0020] The gas cylinder storage introduction table 1 is a turntable driven by a motor, and a trumpet-shaped introduction groove (not shown in the figure) is provided on the turntable corresponding to the entrance of the conveying rack 2. In this way, as the turntable rotates, the gas cylinders stored on the turntable enter the trumpet-shaped introduction groove, and under the guidance of the trumpet-shaped introduction groove, enter the conveying rack 2 one by one.

[0021] The conveying frame 2 includes a front conveyor belt 201 with guide grooves thereon and a rear conveyor mechanism 202 with guide grooves thereon. The gas tank positioning position B is located at the exit of the front conveyor belt 201 , and the rear conveyor mechanism 202 is located in front of the gas tank positioning position B.

[0026] During operation, several gas cylinders A to be filled are placed on the gas cylinder storage introduction platform 1. As the turntable of the gas cylinder storage introduction platform 1 rotates, the gas cylinders stored on the turntable enter the trumpet-shaped introduction slot, and under the guidance of the trumpet-shaped introduction slot, enter the conveyor rack 2 one by one. When the gas cylinder A arrives at the gas cylinder and is ready to enter the positioning position C, the power cover removal mechanism 701 is activated to take the cover A2 from the upper end of the gas cylinder A and send it to the conveyor belt 702, and the conveyor belt 702 sends it to the gas cylinder push-out position D after filling.

The support plate 502 is reset under the drive of the cylinder 501. At the same time, the hook 503 hooks the upper end surface of the gas tank A, so that the spray pipe A1 also descends with the descending of the support plate 502, so that the spray pipe A1 is separated from the sealing ring 406 at the bottom of the cylinder 402. After the gas tank A is pushed out of the gas tank positioning position B by the gas tank pushing mechanism 6 and enters the front end of the rear conveying mechanism 202, the rear conveying mechanism 202 sends the gas tank A to the rear end of the rear conveying mechanism 202, and the power nozzle release mechanism 704 is activated first, taking out the nozzle E from the nozzle conveyor belt 705 and putting it on the spray pipe A1 of the gas tank A, and then the power cover release mechanism 703 takes the cover A2 from the conveyor belt 702 and covers the cover A2 on the upper port of the gas tank A again.
