Description

Technical Field

[0001] The utility model relates to the technical field of automated processing equipment, in particular to a portable heat shrink baking box. Background Art

[0002] Heat shrink tubing has excellent flame retardant and insulating properties, and is very soft and elastic. When heated, heat shrink tubing shrinks quickly and can be widely used in wire connection, wire end processing, solder joint protection, wiring harness identification, resistor and capacitor insulation protection, metal rod or pipe corrosion protection, antenna protection, etc. In traditional production, during the wire production process, the heating element in the hot air blower is used to generate heat, and then the blades in the hot air blower rotate to generate a flowing airflow, blowing out the heat generated by the heating element and acting on the heat shrink tubing, so that the heat shrink tubing shrinks and wraps around the wire.

[0003] In the prior art, the heat shrink tube assembly is generally a U-shaped structure, and both sides of the U-shaped structure are open. This design makes it easy to insert the wires covered with heat shrink tubes into the U-shaped structure, and use a hot air blower to blow hot air out from the inner side walls of the U-shaped structure to heat and lock the heat shrink tube. However, during the heat shrink process, the operator usually holds the cable to operate, so the hot air will escape from the openings on both sides of the U-shaped structure. If the operator does not operate properly or does not take good protection, he or she will easily be burned by the high-temperature hot air, which poses a safety hazard.

[0004] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a convenient heat shrink baking box.

[0007] Furthermore, the safety door is arranged at one or both open sides of the U-shaped structure of the heat shrink tube assembly.

[0008] Furthermore, the safety door adopts a double-door structure.

[0009] Furthermore, the safety door is provided with a plurality of strip holes, and the heat shrink tube assembly is provided with mounting holes corresponding to the strip holes of the safety door, and the safety door is fixed to the heat shrink tube assembly by screws passing through the strip holes and locking them in the mounting holes.

[0010] Furthermore, a winding shaft is provided on the hot air box body, and the winding shaft is arranged beside the open part on one side or both sides of the heat shrink tube assembly.

[0012] Furthermore, a control module is provided on the hot air box body, and the control module includes: a button and a temperature adjustment knob, and the control module is arranged beside the heat shrink tube assembly.

[0013] By adopting the above scheme, the utility model sets a safety door at the opening of the U-shaped structure, and then passes the heat shrink tube through the gap of the safety door, thereby facilitating the heat shrink tube to pass through the heat shrink tube drying assembly for baking and heat shrinkage, while reducing the width of the opening, preventing heat from being blown out from the opening and escaping to cause harm to the operator, thereby improving overall safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of a heat shrink tube assembly arranged on the side of a hot air box.

[0015] Figure 2 This is a structural schematic diagram of a heat shrink tube assembly being arranged on the top of a hot air box. DETAILED DESCRIPTION

[0016] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] See also Figure 1 , Figure 2 The utility model provides a portable heat shrink baking box, comprising: a hot air box body 1, a heat shrink tube assembly 2 arranged on the hot air box body 1, and a safety door 3 movably arranged on the heat shrink tube assembly 2, the air outlet section of the heat shrink tube assembly 2 is provided with a U-shaped structure 21, and the safety door 3 is arranged at the side opening of the U-shaped structure 21.

[0018] When the heat shrink tube needs to be heat-shrunk, heat is generated by the heating element in the hot air box 1, and the fan blades are driven by the motor to rotate, so that the heat in the hot air box 1 is blown out through the heat shrink tube drying assembly 2. A number of air outlets are arranged on the inner side of the U-shaped structure 21 of the heat shrink tube drying assembly 2, so as to facilitate the baking of the heat shrink tube from multiple directions and ensure the stable heat shrink effect of the heat shrink tube. By arranging a safety door 3 at the opening of the U-shaped structure 21, and then passing the heat shrink tube through the gap of the safety door 3, the width of the opening is reduced while facilitating the heat shrink tube to pass through the heat shrink tube drying assembly for baking and heat shrinking, so as to avoid heat from being blown out from the opening and escaping to cause harm to the operator, thereby improving the overall safety.

[0019] The safety door 3 is arranged at one or both open ends of the U-shaped structure 21 of the heat shrink tube assembly 2. According to the operation requirements of the operator, the safety door 3 is arranged at one or both open ends of the U-shaped structure 21. When the safety door 3 is arranged on both sides of the U-shaped structure 21, the operator can hold both ends of the heat shrink tube with both hands to operate when hot air is used to bake the heat shrink tube, thereby improving safety. When the safety door 3 is arranged on one side of the U-shaped structure 21, it is possible to avoid burns to the operator's hand holding the heat shrink tube while facilitating observation of the shrinkage of the heat shrink tube from the other side, thereby avoiding the situation where the safety door 3 is arranged on both sides so that the hot air can only be blown out from the top of the U-shaped structure 21, thereby affecting the operator's observation requirements.

[0020] The safety door 3 adopts a double-door structure. The gap between the door panels on both sides of the double-door structure facilitates the heat shrink tube to pass through the safety door 3, which is convenient for the operation of passing the tube and can also effectively reduce the amount of hot air escaping from the open part of the U-shaped structure 21.

[0021] The safety door 3 is provided with a plurality of strip holes 31, and the heat shrink tube assembly 2 is provided with mounting holes corresponding to the strip holes 31 of the safety door 3. The safety door 3 is fixed to the heat shrink tube assembly 2 by screws passing through the strip holes 31 and being locked in the mounting holes. By changing the relative position of the screws locked on the strip holes 31, the width of the opening gap of the safety door 3 can be adjusted to meet the baking and heat shrinking requirements of heat shrink tubes with different wire diameters.

[0022] The hot air box 1 is provided with a winding shaft 4, which is arranged beside the open part of one or both sides of the heat shrink tube assembly 2. The wire is wound on the winding shaft 4, so that it is convenient to feed the heat shrink tube that has not been processed, or to wind the heat shrink tube that has been heat-shrunk on the winding shaft 4, which is convenient for operation and avoids the wire being placed messily on the operating table, so that the wire can be stored neatly.

[0023] The heat shrink tube assembly 2 is arranged on the top or side wall of the hot air box 1. Figure 2 , the heat shrink tube assembly 2 is arranged on the top of the hot air box 1, which can reduce the overall floor space and operation space when using the oven to bake the heat shrink tube, and effectively overlap the floor space and operation space. Figure 1 The heat shrink tube assembly 2 is arranged on the side wall of the hot air box body, which can facilitate the operator to perform the baking and heat shrinking operation of the heat shrink tube, and can avoid the discomfort of the operator caused by the hot air blown out from the heat dissipation windows on both sides of the hot air box body 1.

[0024] The hot air box 1 is provided with a control module, which includes a button 11 and a temperature adjustment knob 12. The control module is arranged beside the heat shrink tube drying assembly 2. The button 11 for controlling the hot air blowing and the temperature adjustment knob 12 for adjusting the hot air temperature are arranged beside the heat shrink tube drying assembly 2, so that the operator can timely control and adjust various working parameters and working states when performing the baking and heat shrinking operation of the heat shrink tube, thereby improving the convenience of operation control.

[0025] In summary, the utility model sets a safety door at the opening of the U-shaped structure, and then passes the heat shrink tube through the gap of the safety door, thereby facilitating the heat shrink tube to pass through the heat shrink tube drying assembly for baking and heat shrinkage, while reducing the width of the opening, preventing heat from being blown out of the opening and escaping to cause harm to the operator, thereby improving overall safety.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
