[0035] Figure 1 This is a schematic structural diagram of a heat shrink tubing baking device, such as... Figure 1 As shown, and refer to Figures 2 to 3 This utility model provides a heat shrink tubing baking device, which includes a mounting frame 100, a heating mechanism 200, and a fixing mechanism. The heating mechanism 200 is mounted on the mounting frame 100 and is used to blow hot air downwards. The fixing mechanism includes a fixing adjustment plate 310 and a sliding groove plate 320. The adjustment plate is horizontally arranged on the mounting frame 100 and located below the mounting frame 100. The adjustment plate is provided with an adjustment groove extending in the front-back direction, and the sliding groove plate 320 is slidably disposed in the adjustment groove. The sliding groove plate 320 is provided with a plurality of clamping grooves 321 for installing heat shrink tubing.
[0036] Specifically, the adjustment groove on the fixed adjustment plate 310 allows the sliding groove plate 320 to be adjusted to a corresponding position, thereby causing the heat shrink tubing within the groove of the sliding groove plate 320 to slide relative to the air-heating mechanism 200. In other words, when the sliding groove plate 320 causes the heat shrink tubing to slide relative to the air-heating mechanism 200, the length of the heat shrink tubing swept by the hot airflow increases, thus increasing the heating efficiency of the heat shrink tubing. Furthermore, the wire clamping groove 321 can fix the heat shrink tubing to prevent displacement, thereby ensuring uniform heating of the heat shrink tubing. Furthermore, the wire clamping groove 321 can also shape the heat shrink tubing, ensuring the consistency of the product's heat shrinkage.
[0037] Furthermore, the sliding groove plate 320 is slidably arranged, allowing it to be moved to different positions according to the operator's habits, thereby increasing the ease of operation of the device. Furthermore, the multiple wire-clamping grooves 321 can simultaneously hold multiple heat-shrinkable cables, thereby increasing the heating efficiency of the cables. Furthermore, the lengths of the multiple wire-clamping grooves 321 can be different, allowing for the installation of end terminals of multiple heat-shrinkable cables of different lengths.
[0038] During operation, first install the end terminal of the heat-shrinkable tubing to be heat-shrink into the cable clamping groove 321. When it is necessary to adjust the sliding groove plate 320, adjust its position within the adjustment groove. Then, turn on the heating mechanism 200, which blows hot air downwards. The hot air heats the end of the heat-shrinkable tubing located in the cable clamping groove 321, causing the heat-shrinkable tubing to shrink under the action of the hot air. When it is necessary to adjust the position of the hot air blowing on the heat-shrinkable tubing, adjust the position of the sliding groove plate 320 relative to the fixed adjustment plate 310.
[0039] In this embodiment, the sliding groove plate 320 and the sliding groove 311 are frictionally connected, so that the sliding groove plate 320 can remain stationary when it receives a small thrust.
[0040] In this embodiment, the mounting bracket 100 is also provided with a sensor switch assembly 400. The sensor switch assembly 400 is used to activate the heating mechanism 200 when the heat shrink tubing is installed in the cable tray 321, and to turn off the heating mechanism 200 after a preset working time. Specifically, the sensor switch assembly 400 can be an infrared switch.
[0041] In some embodiments of this utility model, such as Figure 2 As shown, the cable tray 321 includes an outer clamping groove section 322 and a cable tray section 323. The cable tray section 323 is arranged along the front-to-back direction, and the heat shrink tubing can be installed into the cable tray section 323. The outer clamping groove section 322 is located at the end of the cable tray section 323, and is coaxial with and connected to the cable tray section 323. The outer clamping groove is used to install the metal clamps on the heat shrink tubing.
[0042] Specifically, a metal clamp is typically installed on the end of the heat-shrinkable tubing to be heat-shrinked. The diameter of the metal clamp is generally larger than that of the heat-shrinkable tubing, clearly indicating the length of the tubing to be heat-shrinked. Therefore, the installation of the metal clamp in the outer clamp groove section 322 further ensures a stable connection of the heat-shrinkable tubing. Furthermore, the outer clamp groove section 322 allows for an embedded installation of the metal clamp.
[0043] In some embodiments of this utility model, such as Figure 3 As shown, the mounting bracket 100 includes a vertical plate 110, a lifting plate 120, and a lifting adjustment component. The vertical plate 110 is vertically arranged and has a lifting groove 111 extending vertically. The lifting plate 120 is horizontally arranged above the sliding groove plate 320. The lifting plate 120 has a protrusion that inserts into the lifting groove 111 and slides up and down along the lifting groove 111. The air heating mechanism 200 is installed on the lifting plate 120. The lifting adjustment component is installed on the vertical plate 110 or the lifting plate 120 and is used to fix the lifting plate 120 to the vertical plate 110 when the lifting plate 120 rises or falls to a preset position in the lifting groove 111.
[0044] Specifically, the lifting plate 120 and the sliding groove plate 320 are arranged parallel to each other. Since the heating mechanism 200 is installed on the lifting plate 120, the lifting plate 120 can move the heating mechanism 200 up and down when it moves up and down, thereby controlling the distance between the heating mechanism 200 and the sliding groove plate 320. Because the magnitude of the hot airflow received by the heat shrink tubing in the cable clamping groove 321 is negatively correlated with the distance between the heating mechanism 200 and the sliding groove plate 320, the lifting plate 120 can be slidably arranged up and down to adjust the heating temperature of the heat shrink tubing.
[0045] Furthermore, generally speaking, there are at least two lifting grooves 111 and at least two corresponding protrusions, thereby increasing the stability of the lifting plate 120 during the lifting process.
[0046] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the lifting plate 120 is provided with a vertically penetrating mounting hole. The air-heating mechanism 200 includes an air-heating gun, which has a heat outlet for blowing hot air, and the heat outlet of the air-heating gun is inserted into the mounting hole.
[0047] Specifically, the heat outlet opens downwards so that the hot air stream blows downwards, thereby directing the hot air stream onto the sliding groove plate 320. Furthermore, the hot air gun 210 is detachably inserted into the mounting hole, thus facilitating the replacement and maintenance of the hot air gun 210.
[0048] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the lifting adjustment component includes a fixing screw 131 and a locking nut 132. One end of the fixing screw 131 is fixedly connected to the protrusion, and the other end extends outward from the lifting groove 111. The locking nut 132 is threaded onto the screw, and the locking nut 132 is located on the outside of the lifting groove 111, with a diameter larger than the width of the lifting groove 111.
[0049] Specifically, the vertical plate 110 is located between the locking nut 132 and the lifting plate 120. The locking nut 132 is designed with a diameter greater than the groove width, so that when the locking nut 132 is tightened towards the lifting plate 120, the locking nut 132 and the lifting plate 120 clamp the vertical plate 110, thereby fixing the position of the lifting plate 120. Furthermore, when the locking nut 132 is tightened away from the lifting plate 120, the locking nut 132 and the vertical plate 110 no longer contact each other, thereby allowing the lifting plate 120 to be adjusted vertically.
[0050] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
