Description

Technical Field

[0001] This utility model relates to the field of heating and shaping equipment technology, specifically a heating and shaping device. Background Technology

[0002] In the fields of plastic parts repair and processing, it is often necessary to heat and shape plastics. Traditionally, this involves directly heating the plastic using tools such as heat guns, and then shaping it manually with simple molds or by hand. Heating and shaping is also commonly used in auto repair shops.

[0003] Patent CN221375952U discloses a hot air gun, which includes a housing and a tail cap. The housing and tail cap form a receiving cavity. The tail cap includes a bottom wall with an opening. The hot air gun also includes a display component disposed in the receiving cavity and facing the opening. The display component includes a control board and a display screen connected to the control board. The display screen faces the opening. The hot air gun also includes a transparent protective cover located between the opening and the display screen. The projection of the transparent protective cover on the bottom wall covers the opening.

[0004] The hot air gun described above has only a single hot air output function and lacks a structure specifically adapted for plastic shaping. In the actual plastic part repair and shaping process, the heated plastic needs to be quickly fixed in shape with the help of a shaping structure. However, the hot air gun described above requires additional manual molds or manual operation. When operating manually, the operator's hands need to be close to the hot air gun nozzle and the hot plastic part, which poses a safety hazard of being burned by the hot air or plastic. It also cannot ensure that the force is applied evenly during the shaping process, further reducing the shaping quality. At the same time, manual shaping is inefficient and difficult to adapt to the needs of batch or urgent plastic part repair. Utility Model Content

[0005] The purpose of this utility model is to provide a heating and shaping device to solve the technical problems mentioned in the background art, which are that the existing hot air guns only have a single hot air output function, lack a special structure adapted to plastic shaping, and need to be used with manual molds or operated by hand. This not only poses a safety hazard of burns to the operator's hands when they are close to the high temperature area, but also cannot ensure uniform shaping force, resulting in low shaping quality. In addition, manual shaping is inefficient and cannot meet the needs of batch or emergency plastic parts repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heating and shaping device includes a hot air gun. Two sets of cones are fixedly installed at one end of the handle guard plate of the hot air gun. A shaping mechanism is rotatably installed between the two sets of cones. The adjustment end of the shaping mechanism extends from the guide rail through the space of the handle guard plate for the user to pull. The guide rail is opened at one end of the handle guard plate.

[0008] As a further embodiment of this utility model, the shaping mechanism includes a connecting plate, with turntables fixedly installed at both ends of the connecting plate, so that the connecting plate is rotated and installed in two sets of cones and located between the two sets of cones. A shaping plate is fixedly installed at the other end of the connecting plate, and the shaping plate is in the shape of an arc-curved hemisphere.

[0009] As a preferred embodiment of this utility model, a heat-conducting mesh is embedded in one end of the inner side of the shaping plate. The heat-conducting mesh can be heated by rotating the connecting plate and facing the nozzle of the hot air gun. When the heat-conducting mesh is facing the nozzle of the hot air gun, the connecting plate will also fit against the lower end of the outer surface of the hot air gun body.

[0010] As a preferred embodiment of this utility model, one end of a torsion spring is fixedly connected to the turntable at both ends of the connecting plate, while the other end of the torsion spring is fixedly connected inside the cone, so that the torsion spring can apply a clockwise torsion force to the connecting plate.

[0011] As a preferred embodiment of this utility model, a toothed ring is provided on the outer surface of one end of the connecting plate. The toothed ring meshes with the toothed plate. The toothed plate is fixedly installed at one end of the guide block, while the guide block is slidably installed in the guide opening through the guide openings on both sides.

[0012] As a further embodiment of this utility model, a trigger is fixedly installed at one end of the guide block that slides through the guide rail opening, and the trigger is located inside the handle guard plate of the hot air gun.

[0013] Compared with the prior art, the beneficial effects of the heating and shaping device of this utility model are as follows:

[0014] Through the meshing transmission of the trigger, toothed plate, and gears, as well as the automatic reset design of the torsion spring, the shaping plate can quickly and accurately switch between two working modes: "heating standby" and "avoiding airflow". This not only ensures that the hot air can fully soften the workpiece without obstruction and avoid uneven local heating, but also allows the shaping plate to immediately reset and receive continuous heating when needed, maintaining the optimal shaping temperature. The operation process is integrated into the single-handed action of pulling and releasing the trigger, which significantly improves the intuitiveness, continuity, and efficiency of operation, reduces the dependence on the operator's experience, and ensures the stability and consistency of shaping quality.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0022] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0023] See Figure 1 As shown in the figure, a heating and shaping device according to an embodiment of the present invention includes a hot air gun 1. Two sets of cones 101 are fixedly installed at one end of the handle guard plate of the hot air gun 1. A shaping mechanism 2 is rotatably installed between the two sets of cones 101. The adjustment end of the shaping mechanism 2 extends from the guide rail opening 102 into the space of the handle guard plate for the user to snap on. The guide rail opening 102 is opened at one end of the handle guard plate.

[0024] In this embodiment of the invention, during the shaping operation, the hot air gun 1 is activated, outputting hot air at a preset temperature from its nozzle. At this time, the shaping mechanism 2 is in its initial position and is squeezed by the operator to offset it from the nozzle of the hot air gun 1. This allows the workpiece to be shaped to be fully heated and softened by the hot air gun 1, preventing uneven heating caused by the shaping mechanism 2 blocking the hot air. This ensures that the workpiece is heated and softened to a malleable state. Once the surface of the workpiece is observed to be slightly softened and deformable to the touch, the operator releases the pressure on the initial position of the shaping mechanism 2. At this point, the shaping mechanism 2 will automatically rotate to face the nozzle of the hot air gun 1 and be continuously heated by the hot air. Then, the shaping end of the heated shaping mechanism 2 is gradually brought closer to and attached to the softened surface of the part to be shaped. Once the shaping end of the shaping mechanism 2 is fully attached to the part, the operator can adjust the pressing and smoothing force according to the shaping requirements until the part is pressed into a standard shape. Then, the hot air gun 1 can be turned off, and the part can be removed after it has completely cooled and solidified. In addition, the step of manually positioning the heated part in traditional manual shaping is eliminated, and no additional tools or repeated adjustments to the position of the shaping mechanism 2 are required. Even those with little experience can quickly master the operation process, significantly improving the ease of operation.

[0025] like Figures 2-3 As shown, the shaping mechanism 2 includes a connecting plate 204, with turntables fixedly installed at both ends of the connecting plate 204, so that the connecting plate 204 can be rotated and installed in two sets of cones 101 and located between the two sets of cones 101. A shaping plate 207 is fixedly installed at the other end of the connecting plate 204, and the shaping plate 207 is in the shape of an arc-curved hemispherical shape.

[0026] A heat-conducting mesh 208 is embedded in one end of the inner side of the shaping plate 207. The heat-conducting mesh 208 can be heated by rotating the connecting plate 204 to face the nozzle of the hot air gun 1. When the heat-conducting mesh 208 faces the nozzle of the hot air gun 1, the connecting plate 204 will also press against the lower end of the outer surface of the hot air gun 1. One end of a torsion spring 206 is fixedly connected to the turntable at both ends of the connecting plate 204, and the other end of the torsion spring 206 is fixedly connected to the cone 101, so that the torsion spring 206 can apply a clockwise torsional force to the connecting plate 204.

[0027] A toothed ring 205 is provided on the outer surface of one end of the connecting plate 204. The toothed ring 205 meshes with the toothed plate 203. The toothed plate 203 is fixedly installed on one end of the guide rail block 201, while the guide rail block 201 is slidably installed in the guide rail opening 102 through the guide openings on both sides. A trigger 202 is fixedly installed on one end of the guide rail block 201 that slides through the guide rail opening 102. The trigger 202 is located inside the handle guard plate of the hot air gun 1.

[0028] When the device is not started, the torsion spring 206 inside the cone 101 applies a clockwise torsional force to the connecting plate 204, which causes the connecting plate 204 to move the shaping plate 207 to the initial position. At this time, the shaping plate 207 will be opposite to the nozzle of the hot air gun 1, and the heat-conducting mesh 208 inside the shaping plate 207 will also be aligned with the nozzle. Due to the good thermal conductivity of the heat-conducting mesh 208, heat is quickly transferred to the shaping plate 207, causing it to heat up rapidly. At the same time, the connecting plate 204 is in close contact with the lower end of the outer surface of the hot air gun 1, providing stable support for the shaping plate 207 and preventing it from shaking.

[0029] During use, the operator can pull the trigger 202 located inside the handle guard plate according to the material and thickness of the part to be shaped and the expected shaping effect. The trigger 202 drives the guide block 201 to slide along the guide port in the guide rail 102. The sliding of the guide block 201 causes the toothed plate 203 fixed at one end to move synchronously. Because the toothed plate 203 and the toothed ring 205 on the connecting plate 204 mesh with each other, the linear movement of the toothed plate 203 causes the toothed ring 205 to rotate, which in turn causes the connecting plate 204 to rotate downward about the turntables at both ends as the axis, thus achieving the goal of offsetting it from the muzzle of the hot air gun 1, so that the hot air gun 1 can fully blow hot air onto the part to be shaped. When it is observed that the part to be shaped has been sufficiently softened, the operator can slowly release the trigger 202. Under the action of the reset torque stored in the torsion spring 206 in the cone cylinder 101, the connecting plate 204 will automatically reverse the time. The needle rotates and, through the engagement of the toothed ring 205 and the toothed plate 203, drives the guide block 201 and the trigger 202 to slide in the opposite direction along the guide opening 102, returning to the initial position. During this process, the shaping plate 207 smoothly flips upward and finally resets to its inner side. The heat-conducting mesh 208 is once again precisely aligned with the nozzle of the hot air gun 1. The continuously sprayed hot air quickly heats the heat-conducting mesh 208 and the shaping plate 207 tightly connected to it, allowing it to reach a suitable working temperature within a few seconds. Subsequently, the operator can smoothly move the hot air gun 1 so that the preheated shaping plate 207 with a specific curvature gradually approaches and gently adheres to the softened surface of the workpiece. By applying different degrees of pressure with the wrist and using the curved surface of the shaping plate 207 for smoothing and shaping operations, the material can be precisely shaped into the required hemispherical shape or other standard shapes.

[0030] During the shaping process, the shaping plate 207 is continuously heated by hot air, thus maintaining a stable working temperature. This effectively prevents problems such as premature hardening of the material surface or incomplete shaping caused by a drop in tool temperature, ensuring molding quality. Furthermore, the device integrates heating, positioning, and shaping functions into one unit, and the working mode can be smoothly switched by simply operating the trigger 202. This greatly simplifies the operation process, reduces reliance on operator experience, and improves the efficiency and consistency of shaping operations.

[0031] In summary, this utility model embodiment integrates heating, positioning, and shaping functions into one unit, allowing for smooth switching of working modes with a simple trigger 202 operation. It eliminates the need for additional tools or repeated adjustments to the position of the shaping mechanism 2, greatly simplifying the operation process, reducing reliance on operator experience, and improving the efficiency and consistency of shaping operations.

The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
