Description

Technical Field

[0001] The utility model relates to the technical field of stentering and setting, in particular to a hot air jetting device for a stentering and setting machine. Background Art

[0002] The stenter is a Lift-Matic pneumatically controlled lifting and lowering insulated door panel forming machine, which can be widely used in the finishing process of various textiles such as woven fabrics and knitted fabrics.

[0003] The patent with publication number CN212925457U discloses a hot air injection device for a stenter setting machine, which includes a shell, a moving mechanism installed at the bottom end of the inner cavity of the shell; a fixing mechanism installed at the top end of the moving mechanism. The device can compress the spring by pressing the button downward, which can drive the button to move out of the inner cavity of the card slot, and move the baffle plate outward to drive the slider to move outward in the inner cavity of the slide slot, so that the space of the inner cavity of the shell is increased, the injection range of the hot air is improved, and the hot air can be evenly distributed on the outer wall of the cloth, thereby ensuring the setting effect of the stenter setting machine;

[0004] However, the device has the problem that after the button is pressed to compress the spring, the button moves out of the slot and the baffle can be moved outward to a suitable position. Then, with the elastic force of the spring, the button is re-engaged in the slot to limit the baffle, thereby increasing the hot air spray range, and vice versa. However, when adjusting the baffle position to adjust the hot air spray range, the slot will pop out every time the button reaches a position. At this time, it is necessary to continue pressing the button to adjust it. Moreover, when the hot air spray range is expanded, the slot in the middle is vacant, and part of the hot air will be sprayed out from the slot, thereby causing a waste of hot air resources. For this reason, a hot air injection device for a stentering forming machine is proposed to solve the problem that the existing hot air injection device is difficult to quickly adjust the injection range.

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.

[0025] Example: See Figure 1-5A hot air injection device for a stenter setting machine comprises an air guide shell 1, one end of the air guide shell 1 is interconnected and fixedly connected with an air inlet pipe 2, the other end of the air guide shell 1 is provided with an adjustment mechanism 3, the inner cavity of the air guide shell 1 is symmetrically provided with two adjustment shells 4, both sides of the air guide shell 1 are provided with movable plates 5, the top of the adjustment shell 4 is provided with a plurality of card slots 6, the inner cavity of the card slot 6 is provided with a card plate 7, the bottom boundaries of both sides of the card plate 7 are provided with chamfers 8, both sides of the top of the air guide shell 1 are fixedly connected with a fixing frame 9, the inner cavity of the fixing frame 9 passes through and is slidably connected with a limit rod 10, and the outer ring of the limit rod 10 is provided with a spring 11.

[0026] Furthermore, the movable plate 5 is fixedly connected to the adjusting shell 4, a sealing gasket is arranged between the adjusting shell 4 and the air guide shell 1, the movable plate 5 is fixedly connected to the stabilizing slide bar 13 on one side facing the air guide shell 1, the stabilizing slide bar 13 penetrates the inner cavity of the air guide shell 1 and is slidably connected, when the movable plate 5 is used to move the adjusting shell 4 to adjust the hot air injection range, the sealing strip is used to improve the sealing between the air guide shell 1 and the adjusting shell 4, and the stabilizing slide bar 13 is used to improve the stability of the adjusting shell 4 when moving.

[0027] Furthermore, the clamping plate 7 penetrates the air guide housing 1 and is slidably connected, and the intersection of the obtuse angle position of the chamfer 8 is slightly higher than the top boundary of the inner cavity of the clamping slot 6 .

[0028] Furthermore, the card plate 7 is fixedly connected to the limit rod 10, and the top and bottom of the spring 11 are fixedly connected to the fixed frame 9 and the card plate 7 respectively. The movable plate 5 is used to move the adjustment shell 4 to the outside of the air guide shell 1. During the process, the chamfer 8 is cooperated, and the card plate 7 automatically moves out of the card slot 6 and compresses the spring 11 under the limit of the limit rod 10 in the fixed frame 9. After the adjustment shell 4 moves to a suitable position, the card plate 7 cooperates with the spring 11 and automatically snaps into the card slot 6 to fix the position of the adjustment shell 4 to expand the spray range. Conversely, the hot air spray range can be reduced by the same token, and the hot air spray range of the hot air spray device of this stenter setting machine can be conveniently adjusted.

[0029] Furthermore, the adjustment mechanism 3 includes a fixed frame 301 fixedly connected to the outside of the air guide shell 1, and the inner cavity of the fixed frame 301 is provided with a plurality of adjustment plates 302. The adjustment plates 302 are rotatably connected in the fixed frame 301 by means of a rotating shaft 303.

The zero scale line of the scale 12 is located in the middle of the air guide shell 1 and is aligned with the joint of the two adjustment shells 4. When the movable plate 5 is used to move the adjustment shell 4 to adjust the hot air spray range, the scale 12 at one end of the air guide shell 1 can be used to accurately control the moving distance of the adjustment shell 4, thereby achieving the purpose of accurately adjusting the spray range of the hot air spray device according to the range of hot air spray required for the cloth.

[0032] Working principle: When this hot air injection device is used in a stenter setting machine, after the external hot air pipe is connected to the air inlet pipe 2, the air can be introduced into the air guide shell 1 and the adjustment shell 4 and then sprayed out to perform cloth setting and other processing. If the cloth is wide and the hot air injection range needs to be adjusted, the movable plate 5 is directly used to move the adjustment shell 4 to the outside of the air guide shell 1. During the process, the chamfer 8 is cooperated, and the card plate 7 automatically moves out of the card slot 6 and compresses the spring 11 under the limit of the limit rod 10 in the fixed frame 9. After the adjustment shell 4 moves to a suitable position, the spring 11 is cooperated, and the card plate 7 automatically snaps into the card slot 6 to fix the position of the adjustment shell 4 to expand the injection range. Conversely, the hot air injection range can be reduced by the same token, which solves the problem that the existing hot air injection device is difficult to quickly adjust the injection range.
