Description

Technical Field

[0001] The utility model relates to the technical field of perfluoroethylene packaging, in particular to high-precision perfluoroethylene packaging equipment. Background Art

[0002] Perfluoroethylene is a colorless, tasteless, odorless, flammable gas at room temperature and pressure. It is chemically very stable and insoluble in water, but soluble in organic solvents such as ethanol and ether. Due to its excellent chemical and thermal stability, perfluoroethylene is widely used in the manufacture of various fluoroplastics, fluororubbers, fluoro coatings and other products, such as polytetrafluoroethylene. Existing gas filling devices cannot better fix and clamp gas cylinders according to the size of the gas cylinders to be filled, causing some inconvenience in replacement and fixing. In addition, most special gas filling devices do not have anti-dumping structures, which can easily cause danger to gas cylinders during use.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN219263936U discloses an anti-dumping special gas dispensing device, including a workbench, a placement groove is provided on the upper surface of the workbench, a turntable is rotatably connected to the upper surface of the placement groove, a bottle groove is provided on the upper surface of the turntable, a slide groove is provided on the upper surface of the turntable, and a sliding block is slidably connected to the inner wall of the slide groove. The two arc-shaped support plates are pulled apart by the elasticity of the spring, and then the gas bottle to be filled is placed in the bottle groove. The arc-shaped support plate is driven by the rebound force of the spring to support and fix the bottle body, and gas bottles of different sizes can be supported and fixed at the corners to prevent the bottle body from tipping over during filling.

[0004] The disadvantage of the above-mentioned prior art solution is that although the arc-shaped supporting plate can be easily pulled open to place the gas cylinder through the elasticity of the spring, after the gas cylinder is filled, the supporting plate needs to be manually loosened. For large-scale, continuous filling operations, this operation may be cumbersome and affect work efficiency. Utility Model Content

[0005] The utility model aims to provide a high-precision perfluoroethylene packaging equipment to solve the technical problem in the prior art that workers are required to manually loosen the supporting plate, which is not conducive to large-scale and continuous gas cylinder packaging operations and affects work efficiency.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions: a perfluoroethylene high-precision packaging equipment, including a workbench, a gas cylinder, a feeding mechanism and a filling mechanism, the top of the gas cylinder is provided with an air inlet, the feeding mechanism includes an active roller, a driven roller and a conveyor belt, the active roller and the driven roller are respectively rotatably arranged at the two ends of the workbench, the conveyor belt is wound between the active roller and the driven roller, the filling mechanism includes a guide rod, a fixed plate, a movable plate, a limit cover, a telescopic rod and a clamping block, the guide rod is fixedly installed on the workbench, the fixed plate The plate is fixedly arranged on the top of the guide rod, the movable plate is slidably arranged on the guide rod and is located above the conveyor belt, the limit cover is fixedly arranged on the bottom of the movable plate, an inflation head for cooperating with the air inlet is installed in the limit cover, the telescopic rod is fixedly arranged on the fixed plate, the movable plate is fixedly connected to the output end of the telescopic rod, a plurality of clamping blocks are provided, and are arranged in a concentric ring shape in the limit cover, a clamping groove matching the shape of the gas cylinder is provided on one side of the clamping block, and an inclined surface for guiding the gas cylinder into the clamping groove is provided at the bottom of the clamping groove.

[0007] As a further solution of the utility model: a slide groove is provided in the limit cover, and a slide rod slidably matched with the slide groove is provided on the other side of the clamping block.

[0008] As a further solution of the utility model: a spring is wound around the outer side of the slide rod, one end of the spring is connected to the slide groove, and the other end of the spring is connected to the clamping block.

[0009] As a further solution of the utility model: a bottle blocking plate extending downward is provided at the bottom of the limiting cover, and an arc-shaped groove is provided on the side of the bottle blocking plate, and the arc-shaped groove matches the shape of the gas cylinder.

[0010] As a further solution of the utility model: a guide plate for guiding the gas cylinder into the arc-shaped groove is provided at the notch of the arc-shaped groove.

[0011] As a further solution of the utility model: two guide plates are provided, and are relatively fixedly arranged at two ends of the notch of the arc-shaped groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The gas cylinder is transported to the bottom of the movable plate by the conveyor belt. Then, the telescopic rod is extended to push the movable plate and the limit cover downward along the guide rod until the clamping block contacts the gas cylinder. Under the guidance of the inclined plane, the gas cylinder smoothly enters the clamping groove and is stably clamped to ensure the accuracy of filling. After the filling is completed, the telescopic rod shrinks to release the gas cylinder, and the conveyor belt restarts to transport the filled gas cylinder to the next work area or collection area. The entire filling process is highly automated. From the transmission, clamping, filling to the release of the gas cylinder, no direct human intervention is required, which significantly reduces the difficulty of operation and labor costs. At the same time, the equipment can quickly complete the subpackaging of gas cylinders, which is suitable for large-scale and continuous production needs.

[0014] 2. When the limit cover descends, the clamping block slides in the slide groove through the slide rod and gradually approaches the gas cylinder. Due to the elastic effect of the spring, the clamping block can be adaptively adjusted according to the diameter of the gas cylinder to ensure that the clamping block can tightly clamp the gas cylinder. When the gas cylinder is fully clamped, the inflation head in the limit cover accurately docks with the air inlet at the top of the gas cylinder. The filling mechanism starts to work and fills perfluoroethylene into the gas cylinder through the inflation head. After the filling is completed, the telescopic rod contracts, driving the movable plate and the limit cover to move upward, releasing the clamped gas cylinder. Since the clamping block can be adaptively adjusted according to the diameter of the gas cylinder, the equipment can clamp gas cylinders of different diameters, which improves the versatility and flexibility of the equipment.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 6 As shown, a high-precision perfluoroethylene packaging equipment includes a workbench 1, a gas cylinder 2, a feeding mechanism 3 and a filling mechanism 4. The top of the gas cylinder 2 is provided with an air inlet 21. The gas cylinder 2 is a container for packaging and storing perfluoroethylene. The top of the gas cylinder 2 is provided with an air inlet 21 for connecting with the filling head 47 of the filling mechanism 4, so as to perform the packaging operation of the perfluoroethylene gas.

[0027] The feeding mechanism 3 includes an active roller 31, a driven roller 32 and a conveyor belt 33. The active roller 31 and the driven roller 32 are rotatably arranged at the two ends of the workbench 1 respectively, and the conveyor belt 33 is wound between the active roller 31 and the driven roller 32. Among them, the filling mechanism 4 is located above the conveyor belt 33. The active roller 31 is driven by a rotating motor or other power source to make the conveyor belt 33 circulate between the active roller 31 and the driven roller 32, thereby continuously transporting the gas cylinders 2 to be packaged with perfluoroethylene to the filling mechanism 4, and transporting the gas cylinders 2 in which the perfluoroethylene is packaged in the filling mechanism 4 to the next process.

[0028] The filling mechanism 4 includes a guide rod 41, a fixed plate 42, a movable plate 43, a limit cover 44, a telescopic rod 45 and a clamping block 46. The guide rod 41 is fixedly installed on the workbench 1, the fixed plate 42 is fixedly set on the top of the guide rod 41, the movable plate 43 is slidably set on the guide rod 41 and is located above the conveyor belt 33, the telescopic rod 45 is fixedly installed on the fixed plate 42, and the movable plate 43 is fixedly connected to the output end of the telescopic rod 45. The upward and downward movement of the movable plate 43 is controlled by the extension and retraction of the telescopic rod 45.

[0029] The limiting cover 44 is fixedly mounted on the bottom of the movable plate 43, and an inflation head 47 for cooperating with the air inlet 21 is installed in the limiting cover 44. A plurality of clamping blocks 46 are provided, and are arranged in a concentric ring shape in the limiting cover 44. A clamping groove 48 matching the shape of the gas cylinder 2 is provided on one side of the clamping block 46, and a slope 49 for guiding the gas cylinder 2 into the clamping groove 48 is provided at the bottom of the clamping groove 48.

[0030] When the gas cylinder 2 on the conveyor belt 33 is moved to the bottom of the movable plate 43 by the feeding mechanism 3, the conveyor belt 33 stops rotating to ensure that the gas cylinder 2 remains stationary during the filling process. After the conveyor belt 33 stops, the telescopic rod 45 begins to extend. Since the movable plate 43 is fixedly connected to the output end of the telescopic rod 45, the extension of the telescopic rod 45 pushes the movable plate 43 to move downward along the guide rod 41. As the movable plate 43 and the limit cover 44 move downward, the clamping block 46 in the limit cover 44 and the gas cylinder 2 begin to contact. In particular, the gas cylinder 2 first touches the inclined surface 49 at the bottom of the clamping groove 48. Under the guidance of the inclined surface 49, the gas cylinder 2 is gradually pushed into the clamping groove 48 in the clamping block 46 to achieve centering. The shape of the clamping groove 48 matches the shape of the gas cylinder 2, ensuring that the gas cylinder 2 can be stably clamped.

[0031] When the gas cylinder 2 completely enters the clamping groove 48 and is stably clamped, the charging head 47 in the limiting cover 44 is accurately docked with the gas inlet 21 at the top of the gas cylinder 2. After the charging head 47 is docked with the gas inlet 21, the filling mechanism 4 starts to work and fills the perfluoroethylene into the gas cylinder 2 through the charging head 47. The filling process can be carried out under the control of a computer to ensure the accuracy and speed of filling. When the gas cylinder 2 is filled to the preset capacity, the filling mechanism 4 stops working. The telescopic rod 45 begins to shrink, driving the movable plate 43 and the limiting cover 44 to move upward, releasing the clamped gas cylinder 2. The conveyor belt 33 restarts to transport the filled gas cylinder 2 to the next work area or collection area.

[0032] The gas cylinder 2 is transported to the bottom of the movable plate 43 by the conveyor belt 33, and then the telescopic rod 45 is extended to push the movable plate 43 and the limit cover 44 to move downward along the guide rod 41 until the clamping block 46 contacts the gas cylinder 2. Under the guidance of the inclined surface 49, the gas cylinder 2 smoothly enters the clamping groove 48 and is stably clamped to ensure the accuracy of filling. After the filling is completed, the telescopic rod 45 contracts to release the gas cylinder 2, and the conveyor belt 33 is restarted to transport the filled gas cylinder 2 to the next work area or collection area. The entire filling process is highly automated, and no direct manual intervention is required from the conveying, clamping, filling to the release of the gas cylinder 2, which significantly reduces the difficulty of operation and labor costs. At the same time, the equipment can quickly complete the subpackaging of the gas cylinder 2, which is suitable for large-scale and continuous production needs.

[0033] refer to Figure 4As shown, in some specific embodiments, in order to make the clamping block 46 suitable for clamping gas cylinders 2 of different diameters, a slide groove 410 is provided in the limiting cover 44, and a slide bar 411 is provided on the other side of the clamping block 46 to slide with the slide groove 410. A spring 412 is wound around the outer side of the slide bar 411, one end of the spring 412 is connected to the slide groove 410, and the other end of the spring 412 is connected to the clamping block 46.

[0034] When the limiting cover 44 descends, the clamping block 46 slides in the slide groove 410 through the slide bar 411 and gradually approaches the gas cylinder 2. Due to the elastic effect of the spring 412, the clamping block 46 can be adaptively adjusted according to the diameter of the gas cylinder 2 to ensure that the clamping block 46 can tightly clamp the gas cylinder 2. When the gas cylinder 2 is completely clamped, the inflation head 47 in the limiting cover 44 is accurately docked with the air inlet 21 at the top of the gas cylinder 2. The filling mechanism 4 starts to work and fills perfluoroethylene into the gas cylinder 2 through the inflation head 47. After the filling is completed, the telescopic rod 45 contracts, driving the movable plate 43 and the limiting cover 44 to move upward, releasing the clamped gas cylinder 2. Since the clamping block 46 can be adaptively adjusted according to the diameter of the gas cylinder 2, the device can clamp gas cylinders 2 of different diameters, thereby improving the versatility and flexibility of the equipment.

[0035] refer to Figure 5 As shown, in some specific embodiments, in order to guide the gas cylinder 2 to enter the limiting cover 44 more stably, a bottle blocking plate 413 extending downward is provided at the bottom of the limiting cover 44, and an arc-shaped groove 414 is provided on the side of the bottle blocking plate 413, and the arc-shaped groove 414 matches the shape of the gas cylinder 2. When the gas cylinder 2 moves to the bottom of the limiting cover 44, the arc-shaped groove 414 can accurately position and fix the gas cylinder 2, reduce the shaking and deviation of the gas cylinder 2 during the positioning process, ensure the accurate alignment of the gas cylinder 2, and thus improve the accuracy and stability during the subpackaging process.

[0036] refer to Figure 5 As shown, in some specific embodiments, in order to ensure that the gas cylinder 2 can enter the arc groove 414 accurately, a guide plate 415 for guiding the gas cylinder 2 to enter the arc groove 414 is provided at the notch of the arc groove 414. Two guide plates 415 are provided, and are relatively fixedly arranged at both ends of the notch of the arc groove 414 to form a guide channel. When the gas cylinder 2 moves to the vicinity of the arc groove 414 driven by the conveyor belt 33, it can smoothly enter the arc groove 414 along the guide plate 415, ensuring that the gas cylinder 2 enters the limit cover 44 more stably.

[0037] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0038] The conveyor belt 33 is driven by the active roller 31 to circulate and transport the gas cylinder 2 to be packaged from one end to the bottom of the filling mechanism 4. When the gas cylinder 2 reaches the predetermined position, the conveyor belt 33 stops rotating to ensure that the gas cylinder 2 remains stationary during the filling process. The telescopic rod 45 begins to extend, pushing the movable plate 43 and the limit cover 44 to move downward.

[0039] As the limiting cover 44 descends, two guide plates 415 form a guide channel at the notch of the arc groove 414 to help the gas cylinder 2 smoothly enter the arc groove 414. The gas cylinder 2 is positioned and fixed by the arc groove 414 to ensure that the gas cylinder 2 enters the limiting cover 44. Then, under the guidance of the inclined surface 49, the gas cylinder 2 enters the clamping groove 48 and is stably clamped.

[0040] When the gas cylinder 2 completely enters the clamping groove 48 and is stably clamped, the filling head 47 in the limiting cover 44 accurately docks with the gas inlet 21 on the top of the gas cylinder 2, and the perfluoroethylene is filled into the gas cylinder 2 through the filling head 47. When the gas cylinder 2 is filled to the preset capacity, the filling mechanism 4 stops working. The telescopic rod 45 begins to shrink, driving the movable plate 43 and the limiting cover 44 to move upward, releasing the clamped gas cylinder 2. The conveyor belt 33 restarts to transport the filled gas cylinder 2 to the next work area or collection area.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
