Description

Technical Field

[0001] The invention relates to the technical field of hot air seam sealing equipment, and in particular to a double air duct conversion device. Background Art

[0002] As the application scope of plastic film fiber cloth becomes wider and wider, hot air seam sealing machine, as the main equipment in the composite process of plastic film fiber cloth, is also widely used. At present, seam sealing machine is mainly used for waterproof processing of seams of various waterproof clothing and outdoor sports products, such as suit raincoats, waterproof shoes and hats, tents, assault suits, waterproof diving suits, protective clothing, etc. Its working principle is to heat with a heating tube, and then use an air pump to blow the heat to the heat sealing tape to make it reach the melting point. Finally, the upper and lower rubber wheels are closed and rotated to make the tape and the fabric tightly combined. In the above steps, the heat needs to be blown to the hot tape through the air nozzle, so the airflow out of the air nozzle is the key factor affecting the seam sealing effect. In the previous process of pressing waterproof tape, since hot air is always blowing, more than 80% of the tape will be folded at the end. First, it affects the appearance. Second, if the tape needs to be cut in the middle, it is not only unsightly, but also affects the waterproof function. In this case, if the waterproof function is to be achieved, the folded part must be manually removed before pressing the tape. After the pressing is completed, the hot press needs to be used for additional pressing, which greatly increases the working hours and energy consumption. Summary of the invention

[0003] The technical problem to be solved by the present invention is that, in view of the above-mentioned defects of the prior art, a dual air duct conversion device is provided to solve the problem of folding of the tail of the tape. On the basis of keeping the original air gun mouth unchanged, the hot air spraying is switched and controlled by adding an air gun connecting inner core, an air gun connecting main body and an air guide duct to avoid the phenomenon of folding of the tape at the end, eliminating the pressing process, achieving a good belt pressing effect and high work efficiency.

[0023] like Figure 1-6As shown, the dual air duct conversion device includes an air gun tube 1, a cylinder 2 is installed on the side of the air gun tube 1, an air gun tube connecting body 3 is installed at the bottom of the air gun tube 1, an air gun tube connecting inner core 4 is installed in the air gun tube connecting body 3, one end of the air gun tube connecting inner core 4 passes through the air gun tube connecting body 3 and is connected to a cylinder swing arm 5, the cylinder 2 is connected to the cylinder swing arm 5 through a cylinder head 6, and an air guide 7 is installed on the side of the air gun tube connecting body 3. It can be understood that the cylinder 2 can be a general cylinder, etc.

[0024] Specifically, an air outlet 8 is provided at the bottom of the air gun tube connection body 3, an air guide port 9 is provided on the left side of the air gun tube connection body 3, an air inlet 10 is provided at the upper end of the air gun tube connection body 3, the air outlet 8 and the air guide port 9 are both connected to the air inlet 10, and a wind gun port 11 connected to the air inlet 10 is provided at the bottom of the air gun tube 1; an inner core socket 12 for inserting the air gun tube connection inner core 4 is provided at the front end of the air gun tube connection body 3, and a first switching air duct 13, a second switching air duct 14 and a third switching air duct 15 are sequentially provided on the air gun tube connection inner core 4, and the first switching air duct 13 and the second switching air duct 14 are both connected to the third switching air duct 15; the air gun tube connection inner core 4 is rotatably installed at the front end of the air gun tube connection body 3, the first switching air duct 13 and the third switching air duct 15 are aligned with each other, and the second switching air duct 14 is located at the upper right of the third switching air duct 15. It can be understood that during installation, the upper end of the air gun tube 1 is installed into the seam sealing machine to connect the hot air. During the tape pressing, the hot air is ejected from the bottom air outlet 8 of the air gun tube connecting the main body 3 to effectively press the tape. At this time, the hot air passes through the air gun mouth 11, the air inlet 10, the first switching air duct 13 and the third switching air duct 15 in sequence, and finally ejected from the air outlet 8; when the tape pressing is about to be completed, the scissors are started to cut the tape, and the air duct conversion device starts the cylinder 2 according to the set requirements, and the cylinder 2 drives the air gun tube connecting the inner core 4 to rotate, and the air Cylinder 2 pushes cylinder swing arm 5 downward, thereby driving the air gun tube connected inner core 4 to rotate counterclockwise. At this time, the second switching air duct 14 is aligned with the air inlet 10, and the first switching air duct 13 is aligned with the air guide port 9. The hot air passes through the air gun mouth 11, the air inlet 10, the second switching air duct 14 and the first switching air duct 13 in turn, and is finally ejected from the air guide port 9 into the air guide duct 7. The hot air from the air gun tube connected to the air outlet 8 at the bottom of the main body 3 is cut off, and no hot air is ejected. The hot air is exported from the air guide duct 7 which is added by design.

[0025] Specifically, a limit pin 16 is provided between the air gun tube connection inner core 4 and the cylinder swing arm 5, the cylinder swing arm 5 is connected to the cylinder head 6 through the swing arm pin 17, and a cylinder tail seat 18 is provided at the upper end of the cylinder 2; a cylinder fixing seat 19 is sleeved on the outer side of the air gun tube 1, and the cylinder fixing seat 19 is connected to the cylinder tail seat 18 through the cylinder tail shaft pin 20. It can be understood that the front end of the air gun tube connection body 3 is provided with a two-step stepped groove, and the end of the limit pin 16 is against the stepped groove, thereby clamping the air gun tube connection body 3, thereby stabilizing the rotation position of the air gun tube connection inner core 4.

[0026] It can be understood that the present invention has a reasonable design and unique structure, which can solve the problem of folding of the belt tail. After testing, the probability of folding is less than 1%, and the folding phenomenon is very slight. It also achieves the same waterproof effect as other glue pressing positions, which not only meets the performance requirements, but also achieves an aesthetically pleasing belt pressing effect. At the same time, it eliminates the auxiliary process of supplementing pressure, thereby improving work efficiency and reducing work energy consumption.
