Description

Technical Field

[0001] This utility model relates to the field of hot air blower technology, and in particular to a novel hot air blower. Background Technology

[0002] Chinese patent application CN118849281A discloses a fully digital intelligent hot air blower, which effectively solves the problems of severe hot air escape, uneven airflow distribution, and low heat energy utilization of traditional U-shaped and round blowers by adopting a structure such as a heating tank, an air outlet facing the feed inlet, an air curtain device, and a buffer box, and significantly improves heating efficiency and uniformity.

[0003] However, in actual use, it was found that the existing technology still has a significant drawback: the hot air blower lacks an auxiliary positioning and stabilizing support mechanism for the workpiece.

[0004] During operation, operators must manually hold and adjust the workpiece (such as wire with heat shrink tubing) to precisely suspend the part to be heated in the center of the heating tank. This not only demands a high level of operator skill, but manual positioning is also prone to errors, easily causing the workpiece to shift to one side of the heating tank, resulting in uneven heating and affecting the heat shrinking quality. Furthermore, it cannot provide effective adaptive adjustments for workpieces of different diameters or shapes, reducing the equipment's versatility and ease of operation.

[0005] Therefore, it is necessary to optimize and improve the workpiece positioning method based on this hot air blower. Utility Model Content

[0006] The main purpose of this utility model is to propose a new type of hot air blower, which aims to add a workpiece positioning function to the existing hot air blower, thereby improving the equipment's versatility and ease of operation.

[0014] By adjusting the installation position of the two positioning members on the moving member, the two positioning members can move closer or further apart, thereby achieving the adjustment of the width of the locking position.

[0015] The movable component can move up and down relative to the frame and lock with the frame to achieve height adjustment of the locking position.

[0016] Preferably, the frame includes two vertically extending support arms;

[0017] The support arm has a strip-shaped hole, and the extension direction of the strip-shaped hole is the same as the extension direction of the support arm.

[0018] The two ends of the movable component are respectively opposite to the two support arms;

[0019] It also includes a locking component, a portion of which passes through the slot and is screwed onto the end of the movable component;

[0020] When the locking member is tightened, the moving member and the support arm are pressed and locked together;

[0021] When the locking member is released, the moving member can move up and down along the strip hole to adjust the height.

[0022] Preferably, the top wall of the movable component has a strip groove;

[0023] The lower end of the positioning element is detachably connected to the strip groove;

[0024] By changing the fixed position of the lower end of the positioning member within the strip groove, the two positioning members can move closer or further apart, thereby achieving the adjustment of the width of the locking position.

[0025] Preferably, the detachable connection between the positioning element and the strip groove is by snap-fit, screw-fit, or plug-in.

[0026] Preferably, it also includes a cooling air head disposed below the air head, the cooling air head being connected to a blower mechanism;

[0027] The cooling head is provided with one or more sets of cooling air outlets, and the air outlets are set to air upwards.

[0028] During operation, the cold air blown out from the cold air vent forms a wall of cold air that surrounds the air head to prevent the hot air from the air head from spreading to the surroundings.

[0029] Preferably, when the cold air vents are in a set, they are U-shaped, circular, or square-shaped air outlet gaps;

[0030] When there are multiple sets of cold air vents, they are multiple long strip-shaped air outlet slits, and the multiple long strip-shaped air outlet slits work together to form a multi-faceted cold air wall surrounding the air head.
