[0021] Reference Figure 1-2 , an embodiment of the present application is proposed, and the gas cylinder drying and vacuuming system described in this embodiment includes:

[0022] The oven 10 is open along two opposite longitudinal sides, and the two sides of the oven 10 are respectively provided with openable and closable doors 11;

[0023] A double-layer circulating conveying device 20 is longitudinally arranged in the oven 10, and two ends of the double-layer circulating conveying device 20 extend from the two open sides of the oven 10 and constitute its feeding end and discharging end respectively. A plurality of material trays 21 for placing gas cylinders are provided on the conveying channel of the double-layer circulating conveying device 20. The double-layer circulating conveying device 20 can convey at least one material tray 21 to the two sides outside the oven 10 respectively.

[0024] In the present application, since a plurality of material trays 21 are arranged on the double-layer circulating conveyor 20 and the two ends of the double-layer circulating conveyor 20 extend from the two sides of the oven 10 respectively, workers can load and unload gas cylinders on both sides of the oven 10 respectively, thereby avoiding the problem of mixing gas cylinders caused by simultaneously loading and unloading gas cylinders that have been dried and those to be dried on the same side of the oven 10;

[0025] In the present application, the double-layer circulating conveyor 20 is provided with a plurality of material trays 21, and the double-layer circulating conveyor 20 can circulate the material trays 21 to both sides of the oven 10. When it is necessary to dry the gas cylinders and load the gas cylinders to be dried onto the double-layer circulating conveyor 20, the double-layer circulating conveyor 20 adopts an intermittent operation mode. At this time, a group of gas cylinders to be dried can be loaded one by one onto the corresponding material trays 21 from one side of the oven 10, and the double-layer circulating conveyor 20 then transports the gas cylinders one by one into the oven 10 until a group of gas cylinders are transported into the oven 10. The double-layer circulating conveyor 20 is stopped, the doors 11 on both sides of the oven 10 are closed, and the oven 10 is started to dry the gas cylinders.

[0026] After a group of gas cylinders are dried, the doors 11 on both sides of the oven 10 are opened, and the double-layer circulating conveying device 20 is started again. The double-layer circulating conveying device 20 operates in intermittent mode again. The double-layer circulating conveying device 20 conveys the dried gas cylinders to their discharge end. Workers can load the gas cylinders to be dried and unload the dried gas cylinders on both sides of the oven 10 at the same time, which is beneficial to improving the drying efficiency of the gas cylinders.

[0027] Those skilled in the art should know that a gap is provided between the lower end of the door 11 and the bottom wall of the oven 10 for the double-layer circulating conveyor 20 to operate, so as to avoid interference between the double-layer circulating conveyor 20 and the door 11 .

[0028] Preferably, a plurality of material trays 21 are continuously distributed on the conveying channel of the double-layer circulating conveying device 20, so that the double-layer circulating conveying device 20 can continuously convey the material trays 21, realize continuous loading and unloading of gas cylinders, which is beneficial to improving the efficiency of loading and unloading of gas cylinders.

[0029] For the continuously running oven 10, the drying temperature is generally between 120°C and 150°C. In order to prevent the safety accidents caused by the worker loading or unloading the gas cylinder and being too close to the oven 10 due to the over-high temperature in the oven 10, the present embodiment also adopts the following measures:

[0030] A material receiving conveying device 30 and a first material pushing mechanism 40 are respectively arranged on both sides of the discharge end of the double-layer circulation conveying device 20, and the material receiving conveying device 30 is distributed laterally. The first material pushing mechanism 40 is used to push the gas cylinder on the upper end of the discharge tray 21 at the discharge end of the double-layer circulation conveying device 20 to the conveying channel of the material receiving conveying device 30, and the material receiving conveying device 30 conveys the gas cylinder on its conveying channel away from the oven 10.

[0031] A feeding conveying device 50 is arranged on one side of the feed end of the double-layer circulation conveying device 20, and the feeding conveying device 50 is distributed in the transverse direction. The feeding conveying device 50 is used to convey the gas cylinders on its conveying channel to the feed end close to the double-layer circulation conveying device 20. The second pushing mechanism 60 is arranged on one side of the feeding conveying device 50, and is used to push the gas cylinders on the feeding conveying device 50 onto the material tray 21 of the double-layer circulation conveying device 20.

[0032] As shown in the accompanying drawings, the double-layer circulation conveying device 20, the feeding conveying device 50 and the receiving conveying device 30 are all double-layer chain conveyors, and the double-layer circulation conveying device 20, the feeding conveying device 50 and the receiving conveying device 30 are all operated in an intermittent mode;

[0033] The feeding conveyor device 50 stops running after conveying the gas cylinder to the feeding end near the double-layer circulation conveyor device 20, and the first pushing mechanism 40 pushes the gas cylinder at the feeding end of the feeding conveyor device 50 onto the material tray 21 of the double-layer circulation conveyor device 20. The double-layer circulation conveyor device 20 and the feeding conveyor device 50 start running synchronously, so that the feeding conveyor device 50 conveys the next gas cylinder to the feeding end near the double-layer circulation conveyor device 20, and the double-layer circulation conveyor device 20 conveys the gas cylinder into the drying oven 10. After a group of gas cylinders to be dried are loaded, the feeding conveyor device 50 stops running, the doors 11 on both sides of the drying oven 10 are closed, and the drying oven 10 is started to dry the gas cylinders.

[0034] After a group of gas cylinders are dried, the doors 11 on both sides of the oven 10 are opened, and the double-layer circulating conveyor 20 is started again. The double-layer circulating conveyor 20 operates in intermittent mode again. The double-layer circulating conveyor 20 conveys the dried gas cylinders to its discharge end, and the first pushing mechanism 40 pushes the gas cylinders at the discharge end of the double-layer circulating conveyor 20 onto the receiving conveyor 30. The double-layer circulating conveyor 20 and the receiving conveyor 30 operate synchronously, and the double-layer circulating conveyor 20 conveys the next gas cylinder to its discharge end, and the receiving conveyor 30 conveys the gas cylinder pushed thereon away from the oven 10.

[0035] In this embodiment, the first pushing mechanism 40 is a telescopic cylinder, the telescopic end of the telescopic cylinder is facing the double-layer circulation conveying device 20, and a first pushing piece is installed on the telescopic end of the telescopic cylinder. The first pushing mechanism 40 can be extended so that the first pushing piece pushes the gas cylinder on the material tray 21 at the discharge end to move to the material receiving conveying device 30.

[0036] The second pushing mechanism 60 is a two-dimensional driving mechanism, and a second pushing piece is installed on the driving end of the two-dimensional driving mechanism. The second pushing mechanism 60 can drive the second pushing piece to move two-dimensionally on the horizontal plane, so that the second pushing piece can extend between two adjacent gas cylinders, and then push the gas cylinders to move to the material tray 21 of the double-layer circulation conveying device 20.

[0037] An arc-shaped buffer may also be provided on one side of the first pushing member and the second pushing member close to the double-layer circulation conveying device 20 to avoid damaging the gas cylinder.

[0038] In order to ensure that the gas cylinders can move smoothly between the double-layer circulation conveying device 20, the material receiving conveying device 30 and the feeding conveying device 50, receiving platforms are respectively arranged between the double-layer circulation conveying device 20 and the material receiving conveying device 30 and the feeding conveying device 50 to ensure that the gas cylinders can move smoothly. Each gas cylinder moves from the feeding conveying device 50 to the receiving platform and then moves to the material tray 21. After the gas cylinder on the material tray 21 moves to the receiving platform, it is moved to the material receiving conveying device 30 under the action of the first pushing mechanism 60.

[0039] In this embodiment, the material tray 21 is a U-shaped tray with an opening facing upward, and the through grooves of the material tray 21 are distributed in the transverse direction, so that when the gas cylinder is placed on the material tray 21, its two ends can be limited by the flanges on both sides of the U-shaped tray, thereby improving the stability of the gas cylinder during movement. The through grooves of the U-shaped tray facilitate the feeding conveying device 50 and the receiving conveying device 30.

[0040] Preferably, the two doors 11 are installed on both sides of the oven 10 through a synchronous opening and closing mechanism. In the present application, the doors 11 on both sides of the oven 10 can be opened and closed synchronously for easy control.

[0041] In this embodiment, the synchronous opening and closing mechanism, which is not shown in the figure, includes a motor, a bidirectional screw and two sliders. The bidirectional screw is longitudinally and rotatably installed on one side of the oven 10, and the two sliders are respectively screwed on the two ends of the bidirectional screw. The two sliders are respectively hinged to one end of the two connecting parts, and the other ends of the two connecting parts are respectively hinged to the two doors 11. The motor is installed on the side wall of the oven 10 and is transmission-connected to the bidirectional screw. The motor can drive the bidirectional screw to rotate to drive the two sliders to slide synchronously to achieve synchronous opening and closing of the door 11.

[0042] In this embodiment, an opening may also be provided at the upper end of the oven 10, and a double door panel is provided at the opening at the upper end of the oven 10. Corresponding semicircular notches are provided at the ends of the double door panels that are close to each other. When the double door panels are connected to a cover driving mechanism on the oven (not shown in the figure), the cover driving mechanism drives the double door panels to close, and the double door panels close to form a circular through hole allowing the gas cylinder to pass through, so that the bottle valve and bottleneck of the gas cylinder are exposed from the upper end of the oven 10 and connected to a vacuum pumping device, while preventing the bottle valve from being damaged by heating.

[0043] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
