They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 3As shown, this embodiment provides a heat shrinking device based on far-infrared radiation, including a frame 1, a lifting driver 3, and a heat shrink box 10. The heat shrink box 10 is slidably mounted on the frame 1. Specifically, in this embodiment, the frame 1 is provided with a vertically extending guide rail 2, and a sliding frame 4 is mounted on the guide rail 2. The sliding frame 4 is fixedly connected to the heat shrink box 10. The lifting driver 3 is mounted on the frame 1. The lifting driver 4 can be a lifting cylinder or a lifting electric cylinder in the prior art. The lifting driver 3 drives the heat shrink box 10, specifically directly connected to the sliding frame 4, to drive the heat shrink box 10 to move up and down; thereby causing the heat shrink box 10 to switch between a waiting position and a working position for heat shrinking, that is, the waiting position is in a high position and the working position is in a low position.

[0020] The heat shrink box 10 includes a box body 11 and two sets of far-infrared heating plates 12 disposed inside the box body 11. The bottom of the box body 11 has a heat-receiving notch 101 that runs through the front and back and extends upward. In this embodiment, the box body 11 is a square box body, and the heat-receiving notch 101 is located in the middle of the bottom of the box body 11. The heat-receiving notch 101 is arranged to run through the front and back and extends upward to half the height of the box body 11. Of course, the height of the heat-receiving notch 101 extending upward can be designed according to the actual situation, and the shape of the box body 11 can also be designed according to the actual situation.

[0021] Specifically, the heat shrink box 10 has a box body 11 formed by splicing two shells on the left and right sides, which facilitates assembly and preparation.

[0022] The far-infrared heating plate 12 is a heating device capable of radiating far-infrared rays. Two sets of far-infrared heating plates 12 are respectively located on the left and right sides of the heating notch 101. The box body 11 of the heat shrink box 10 forms a relatively sealed chamber, which is connected to the outside only through the heating notch 101. The space where the heating notch 101 is located is the working space. By placing the two sets of far-infrared heating plates 12 on the left and right sides of the heating notch 101, the two sets of far-infrared heating plates 12 radiate far-infrared rays into the working space at the heating notch 101 in the middle, making the working space receive more concentrated and uniform radiation. Moreover, compared with conventional infrared radiation, far-infrared radiation has stronger penetration and radiation power.

[0023] During operation, the lifting driver 3 drives the heat shrink box 10 to descend to the working position, and the heat shrink tube to be heat-shrink is placed in the heat-receiving notch 101, so as to radiate heat to the heat shrink tube, so that the heat shrink tube is heat-shrinked and its heat shrink uniformity is better; significantly improving the uniformity of heat shrinking; and the structure is simple and easy to implement.

[0024] Furthermore, in this embodiment, the far-infrared heating plate 12 includes a heating plate and a graphene layer disposed on the surface of the heating plate. The heating plate can be a resistance wire heating plate or the like, as is available in the prior art. The graphene layer is deposited on the surface of the heating plate. When the heating plate is energized and heats up, the graphene, due to its excellent thermal conductivity, can rapidly transfer heat to the surface when the temperature changes, and promotes the release of far-infrared radiation through its unique electronic structure; thus, far-infrared radiation is obtained. Of course, in other embodiments, the structure of the far-infrared heating plate 12 capable of generating far-infrared radiation is not limited to this.

[0025] Furthermore, in this embodiment, the inner wall of the box 11 is provided with a heat insulation layer 13, which can better lock heat inside the box 11, reduce heat loss, and also lower the surface temperature of the box 11 to avoid burns. Furthermore, the heat insulation layer 13 is a structure of at least two layers stacked from the inside out; in this embodiment, it is two layers, using multiple layers for stacking. Different heat insulation materials with different properties can be combined, such as a combination of a flame-retardant material for the innermost layer and a non-flame-retardant material for the outermost layer.

[0026] The bottom of the heat-receiving notch 101 is shaped like an "8". The bottom position is the widest, which can better align with the heat shrink tubing below, allowing the heat shrink tubing to smoothly enter the heat-receiving notch 101 of the box body 11. At the same time, it also reduces the area of ​​the opening, thereby reducing heat loss.

[0027] Furthermore, it also includes a temperature controller 5, which is fixedly mounted on the frame 1. The temperature detection end 6 of the temperature controller 5 is located inside the housing 11. Specifically, the temperature detection end 6 of the temperature controller 5 is located above the heating notch 101 to more accurately sense the temperature within the working space. The control end of the temperature controller 5 is connected to the power supply circuit of the two sets of far-infrared heating plates 12. Based on the detected temperature value, the temperature controller controls the current of the far-infrared heating plates 12 to control the heat output of the far-infrared heating plates 12, thereby achieving constant temperature control of the heat shrink box 10. Specifically, the specific connection structure and control method between the temperature controller 5 and the far-infrared heating plates 12 are existing technologies and will not be described in detail here.

[0028] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
