DETAILED DESCRIPTION

[0023] 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 in 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.

[0024] The utility model provides Figure 1-4 The heat sealing device for valve bags shown in the figure includes a heat sealing table 100, a lifting plate 303 and a guide mechanism 400. A conveyor line 200 is provided on one side of the heat sealing table 100. The conveyor line 200 is used to transport the valve bags to the heat sealing table 100. The valve bags can be translated and transported to the heat sealing table 100 in sequence and at intervals through the conveyor line 200, so as to achieve the purpose of automatic loading and help improve work efficiency. The side of the heat sealing table 100 facing the conveyor line 200 is inclined. The heat sealing table 100 contacts the conveyor line 200 through the inclined side, which can reduce the gap between the two, so that the process of transferring the valve bags from the conveyor line 200 to the heat sealing table 100 is more stable. A gantry bracket 301 is fixedly connected to the top of the heat sealing table 100. A liftable heat sealing mechanism 300 is provided on the inner side of the gantry bracket 301. The heat sealing mechanism 300 is used to align the valve bags on the heat sealing table 100. The valve bag is heat-sealed, and the lifting plate 303 is movably arranged on the inner side of the gantry bracket 301 and can be lifted and lowered with the heat sealing mechanism 300. A positioning baffle 308 is provided on one side of the bottom end of the heat sealing mechanism 300. The positioning baffle 308 is used to block and position the valve bag on the heat sealing table 100. The guide mechanism 400 is arranged at the end position of the top end of the heat sealing table 100. The guide mechanism 400 is used for guiding and positioning the valve bag entering the heat sealing table 100. The conveyor line 200 delivers a single valve bag to the heat sealing table 100. Through the correction effect of the guide mechanism 400, the valve bag can maintain a neat posture and enter the heat sealing table 100. The positioning baffle 308 is then used to limit the valve bag. When the valve bag is against the side wall of the positioning baffle 308, it means that the heat sealing position is reached, and then the heat sealing operation of the valve bag can be completed by descending the heat sealing mechanism 300.

[0025] The heat sealing mechanism 300 includes a lifting device 304 fixedly installed on the top of the gantry bracket 301. In the prior art, the lifting device 304 can be a hydraulic cylinder, a lifting cylinder or an electric telescopic rod, the main purpose of which is to drive the hot pressing device 302 to lift and lower. The hot pressing device 302 is movably arranged on the inner side of the gantry bracket 301. After the hot pressing device 302 is powered on, heat can be generated on its bottom surface, thereby achieving hot pressing of the valve bag. The telescopic end of the lifting device 304 extends to the inner side of the gantry bracket 301 and is fixedly arranged with the middle part of the lifting device 304. An elastic compression spring 306 is fixedly connected between the T-shaped rod 305 and the lifting plate 303. The hot pressing device 302 is located below the lifting plate 303, and the telescopic end of the lifting device 304 is fixedly connected to a T-shaped rod 305. A connecting through hole 307 is provided in the middle of the lifting plate 303. The bottom of the T-shaped rod 305 passes through the connecting through hole 307 and is fixedly connected to the middle of the hot pressing device 302. Through the coordinated use of the T-shaped rod 305, the connecting through hole 307 and the elastic compression spring 306, the lifting device 304 can continue to drive the hot pressing device 302 to move downward after the positioning baffle 308 contacts the surface of the heat sealing table 100, so that the normal operation of the hot pressing device 302 can be not affected when the positioning baffle 308 is in the positioning position;

[0026] Furthermore, a U-shaped frame 309 is fixedly connected to the side of the lifting plate 303 away from the guide mechanism 400, and a connecting bolt 310 is fixedly connected to the top of the positioning baffle 308. The top of the connecting bolt 310 passes through the inner side of the U-shaped frame 309 and extends to the upper position. The top of the connecting bolt 310 is threadedly connected to a clamping nut 311. By using the connecting bolt 310, the clamping nut 311 and the U-shaped frame 309 in coordination, the positioning baffle 308 can be adjusted and fixed in the horizontal position below the lifting plate 303, so that the lateral distance between the positioning baffle 308 and the hot pressing device 302 can be adjusted according to the different positions required for hot pressing of valve bags of different specifications, thereby improving the adaptability of use and better meeting the use requirements.

[0027] In addition, blocking blocks 312 are fixedly connected to the bottom of the two inner walls of the gantry bracket 301, and the height of the blocking blocks 312 is greater than or equal to the height of the positioning baffle 308. The blocking blocks 312 can be used to provide auxiliary support for the lifting plate 303 after the positioning baffle 308 reaches the positioning blocking position, so that the force on the lifting plate 303 is more uniform and it is not easy to be damaged.

[0028] In a preferred embodiment, the guide mechanism 400 includes two guide plates 401 symmetrically arranged at the top of the heat sealing table 100, the ends of the guide plates 401 away from the heat sealing mechanism 300 are bent outward, and the two guide plates 401 are provided with a fixing plate 402 fixed to the top of the heat sealing table 100 on the opposite sides, and a connecting shaft 403 is movably inserted in the middle of the fixing plate 402, one end of the connecting shaft 403 is fixedly connected to the side wall of the guide plate 401, and a fixing bolt 404 is threadedly inserted at the top of the fixing plate 402, and one end of the fixing bolt 404 passes through the inside of the fixing plate 402. And it fits with the outer wall of the connecting shaft 403; by adjusting the distance between the two guide plates 401 and the position on the heat sealing table 100, a channel similar to a figure eight is formed between the two guide plates 401, so that the valve bag can be automatically corrected during the transmission process from the channel between the two guide plates 401, ensuring the neat entry of the valve bag, and at the same time, the locking and fixation between the connecting shaft 403 and the fixed plate 402 is achieved by the fixing bolts 404, which not only makes the position of the guide plate 401 adjustable, but also ensures the stability of the adjusted position of the guide plate 401.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
