The adjustment seat 71 is located in the middle below the frame 1. The two ends of the adjustment seat 71 are rotatably connected to the adjustment trapezoidal lead screw 72 via bearings. The surface of the adjustment trapezoidal lead screw 72 is threaded with a square slider 73. The square slider 73 and the adjustment seat 71 are in close sliding contact. 73 is symmetrically and fixedly connected to two sides of a connecting rod 74. The other end of the connecting rod 74 is connected to the upper part of one side of the heat shrink chamber 3. A bevel gear 75 is fixedly connected to the lower part of the adjusting trapezoidal screw 72. A bevel gear 76 is meshed with one side of the bevel gear 75. A rotating rod 77 is fixedly connected in the middle of the bevel gear 76. The rotating rod 77 and the adjusting seat 71 are rotatably connected by a bearing. An adjusting motor 78 is fixedly connected to one end of the rotating rod 77. The adjusting seat 71 and the frame 1 are connected by a mounting assembly 79.

[0019] By adopting the above technical solution, the regulating motor 78 is started, which drives the rotating rod 77 to rotate. The rotation of the rotating rod 77 drives the second bevel gear 76 to rotate. The rotation of the second bevel gear 76 drives the first bevel gear 75, which is meshed on one side, to rotate. The rotation of the first bevel gear 75 drives the adjusting trapezoidal screw 72 to rotate. The rotation of the adjusting trapezoidal screw 72 drives the square slider 73 to move. The movement of the square slider 73 drives the connecting rod 74 to move. Thus, the connecting rod 74 drives the upper side plate of the heat shrink chamber 3 to move. Under the action of the corrugated plate, the distance between the upper side plate and the lower side plate is adjusted, thereby adjusting the size of the inlet of the heat shrink chamber 3.

[0020] Specifically, the mounting assembly 79 includes a positioning rod 791, a fixing block 792, and a fixing screw 793. The positioning rod 791 is fixedly connected to the middle of the upper part of the adjusting seat 71. The positioning rod 791 is tightly inserted into the frame 1. The two sides of the adjusting seat 71 are symmetrically and fixedly connected to the fixing blocks 792. The fixing screw 793 is inserted in the middle of the fixing block 792. The fixing screw 793 is threadedly connected to the frame 1. One end of the connecting rod 74 is also fixedly connected to the fixing block 792.

[0021] By adopting the above technical solution, the adjusting seat 71 and the frame 1 are connected and positioned by the positioning rod 791, and then the fixing block 792 and the frame 1 are fixed by inserting the fixing screw 793, thereby fixing the adjusting seat 71. Then, the fixing block 792 and the heat shrink chamber 3 are fixed by fixing screw 793, thereby completing the installation of the adjusting assembly 7.

[0022] Specifically, a support plate is fixedly connected to the lower part of the adjusting motor 78, and one side of the support plate is fixedly connected to the adjusting seat 71.

[0023] By adopting the above technical solution, the support plate facilitates the support and fixation of the adjustment motor 78.

[0024] In this embodiment, during use: The adjusting motor 78 is activated, causing the rotating rod 77 to rotate. The rotation of the rotating rod 77 drives the second bevel gear 76 to rotate, which in turn drives the first bevel gear 75, which is meshed with it on one side, to rotate. The rotation of the first bevel gear 75 drives the adjusting trapezoidal lead screw 72 to rotate, which in turn moves the square slider 73. The movement of the square slider 73 moves the connecting rod 74, thereby causing the upper side plate of the heat shrink chamber 3 to move via the connecting rod 74. Under the action of the corrugated plate, the distance between the upper and lower side plates is adjusted. The size of the inlet of the heat shrink chamber 3 is adjusted by means of the adjustment seat 71 and the frame 1 by means of the positioning rod 791. Then, the fixing block 792 and the frame 1 are fixed by means of the fixing screw 793, thus fixing the adjustment seat 71. Then, the fixing block 792 and the heat shrink chamber 3 are fixed by means of the fixing screw 793, thus fixing the adjustment assembly 7. This makes it easy to adjust the distance between the upper and lower side plates of the heat shrink chamber 3 during use, thereby adjusting the opening of the heat shrink chamber 3 and improving the convenience of use.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the positioning component 8 includes a support 81, a positioning screw 82, a throttle 83, a positioning plate 84, and a rubber fastening pad 85. The support 81 is fixedly connected to one side of the support leg 5 at one end of the lower part of the frame 1. The positioning screw 82 is threadedly connected to the middle of the support 81. The throttle 83 is fixedly connected to the upper part of the positioning screw 82. The positioning plate 84 is rotatably connected to the lower part of the positioning screw 82. The rubber fastening pad 85 is fixedly connected to the lower part of the positioning plate 84.

[0026] By adopting the above technical solution, rotating the handle 83 will cause the positioning screw 82 to rotate, and the positioning screw 82 will cause the positioning plate 84 and the rubber fastening pad 85 to move down and press against the ground to position the device. The rubber fastening pad 85 ensures good positioning effect.

[0027] Specifically, a stabilizing slide bar 86 is fixedly connected to one end of the positioning plate 84, and a stabilizing slider 87 is slidably connected to the surface of the stabilizing slide bar 86. One side of the stabilizing slider 87 is fixedly connected to the support leg 5.

[0028] By adopting the above technical solution, the stabilizing slider 87 and the stabilizing rod 86 work together to facilitate the stable movement of the positioning plate 84.

[0029] In this embodiment, when the handle 83 is rotated, the positioning screw 82 rotates, and the positioning plate 84 and the rubber fastening pad 85 move down and press against the ground to position the device. The rubber fastening pad 85 ensures good positioning. The stabilizing slider 87 and the stabilizing slide rod 86 work together to guide and limit the movement of the positioning plate 84, enabling it to move stably. This makes it easy to position the device during use and reduces the installation cost of the device.

[0030] The structure and working principle of the frame 1, conveyor belt 2, heat shrink chamber 3, curtain mechanism 4, support leg 5, and roller 6 in this utility model have been disclosed in a heat shrink packaging machine disclosed in Chinese patent application number 201820430926.8. Its working principle is that the heat shrink chamber 3 includes an outer shell, an inlet, an outlet, an upper side plate, a lower side plate, a corrugated plate, a circulating fan, and a far-infrared heat source. The curtain mechanism 4 includes a fixed plate, a winding rod, a curtain, a positioning groove, a claw, a third nut, and a fourth nut.

[0031] The working principle and usage process of this utility model: This utility model is used for heat shrink packaging of plush toys. In use, the device is moved to the desired position by rollers 6, and positioned by positioning component 8. The packaged plush toy is conveyed by conveyor belt 2 and enters heat shrink chamber 3 for heat shrink packaging. During use, the distance between the upper and lower side plates of heat shrink chamber 3 can be adjusted by adjusting component 7, thereby adjusting the opening size. When adjusting component 7 is in use, adjusting motor 78 is started, which drives rotating rod 77 to rotate. The rotation of rotating rod 77 drives bevel gear 2 76 to rotate, which in turn drives bevel gear 1 75 meshing on one side to rotate. The rotation of bevel gear 1 75 drives adjusting trapezoidal lead screw 72 to rotate, which in turn drives square slider 73 to move. The movement of square slider 73 drives connecting rod 74 to move, thereby moving the upper side plate of heat shrink chamber 3 through connecting rod 74. Under the action of the corrugated plate, the distance between the upper and lower side plates is adjusted, thus adjusting the heat shrinkage. The size of the inlet of the heat shrink chamber 3 is determined by positioning the adjusting seat 71 and the frame 1 using the positioning rod 791. Then, the fixing block 792 and the frame 1 are fixed by inserting the fixing screw 793, thus fixing the adjusting seat 71. The fixing block 792 and the heat shrink chamber 3 are then fixed by the fixing screw 793, thus completing the installation of the adjusting assembly 7. This allows for convenient adjustment of the distance between the upper and lower side plates of the heat shrink chamber 3 during use, thereby adjusting the opening of the heat shrink chamber 3 and improving ease of use. When using the positioning assembly 8, rotating the handle 83 causes the positioning screw 82 to rotate, which in turn causes the positioning plate 84 and the rubber fastening pad 85 to move downwards and press against the ground, positioning the device. The rubber fastening pad 85 ensures good positioning. The stabilizing slider 87 and the stabilizing rod 86 work together to guide and limit the movement of the positioning plate 84, allowing it to move stably. This facilitates convenient positioning of the device during use and reduces the installation cost.
