[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 In this embodiment of the utility model, a drying device for producing plastic packaging boxes includes a mounting frame 1, a cast iron metal frame 2 installed on the outside of the mounting frame 1, a plastic packaging box conveyor belt 3 installed on the top of the cast iron metal frame 2, a hot air drying device 4 installed on the top of the mounting frame 1, a maintenance rotating door 5 rotatably connected to the outside of the mounting frame 1 via a rotating shaft, a closing connection mechanism 6 fixed to the outside of the mounting frame 1, and a drying limiting mechanism 7 installed on the outside of the mounting frame 1.
[0022] The drying limiting mechanism 7 includes a high-temperature resistant housing 71. A support spring 72 is provided on one inner wall of the high-temperature resistant housing 71. One end of the support spring 72 is connected to a limiting connecting pad 73. A movable connecting post 74 is fixed to one side of the limiting connecting pad 73, penetrating to the other side. An assembly pad 76 is installed at one end of the movable connecting post 74. A cast iron frame 77 is provided on the outer side of the assembly pad 76. A cast iron pad 78 is fixed to one end of the cast iron frame 77. A limiting housing 75 is installed on the outer side of the high-temperature resistant housing 71. A handle post 79 is fixed to the outer side of the assembly pad 76. An anti-scalding handle 710 is provided at one end of the handle post 79. The high-temperature resistant housing 71 and the mounting bracket 1 are fixedly connected. The interior has a through hole to accommodate the movement of the handle column 79. When the hot air drying device 4 performs the corresponding air drying, the support spring 72 inside the high-temperature resistant shell 71 pushes the limiting connecting pad 73 to move. This allows the limiting connecting pad 73 to move the movable connecting column 74, and the movable connecting column 74 to move the assembly pad 76 and the cast iron frame 77 that are fixedly connected to it. This allows the cast iron pad 78 on the outside of the cast iron frame 77 to fit against the outside of the corresponding plastic packaging box, which plays a role in limiting and positioning the outside of the plastic packaging box. It also ensures the stability of the plastic packaging box during the drying process, avoids the problem of the plastic packaging box being tilted, which affects the drying effect, and improves the drying effect of the plastic packaging box.
[0023] In one embodiment of this utility model, the closing connection mechanism 6 includes a cast iron shell 61, a cast iron positioning post 62 fixed to the outside of the cast iron shell 61, a shielding mounting pad 63 provided at one end of the cast iron positioning post 62, a guide connecting sleeve 64 fixed to the outside of the mounting bracket 1, an anti-detachment slider 65 slidably connected to the guide connecting sleeve 64 through a sliding groove, a carbon steel connecting block 66 fixed to the bottom of the anti-detachment slider 65, a metal connecting handle 67 installed at the bottom of the carbon steel connecting block 66, a movable connecting pad 68 provided at the bottom of the metal connecting handle 67, a mounting positioning block 69 movably sleeved on the outside of the cast iron positioning post 62, a groove provided inside the movable connecting pad 68, and the size of the groove is adapted to the size of the mounting positioning block 69, one side of the movable connecting pad 68 fitting against the outside of the cast iron shell 61, the cast iron shell 61 and the maintenance rotating door 5 are fixedly connected, and a hot air drying device 4 is included. Then, corresponding air drying can be performed. When it is necessary to open the maintenance rotating door 5 to maintain and repair the internal components of the mounting bracket 1, the operator only needs to move the mounting positioning block 69 on the outside of the cast iron positioning column 62 to allow the mounting positioning block 69 to disengage from the preset groove of the corresponding movable connecting pad 68, thereby releasing the locking of the movable connecting pad 68. The blocking mounting pad 63 at one end of the cast iron positioning column 62 serves to limit the mounting positioning block 69. At the same time, after the movable connecting pad 68 is unlocked, the metal connecting handle 67 can be moved vertically to move the carbon steel connecting block 66 and the movable connecting pad 68, and to make the anti-disengagement slider 65 slide in the groove of the corresponding guide connecting sleeve 64. This can quickly release the lock of the cast iron outer shell 61 and make it easy to open the maintenance rotating door 5 to maintain and repair the internal components of the mounting bracket 1, which is beneficial for the drying operation of the plastic packaging box.
[0024] The working principle of this utility model is as follows: This device is equipped with a drying limiting mechanism 7. When the hot air drying device 4 performs corresponding air drying, the supporting spring 72 inside the high-temperature resistant shell 71 pushes the limiting connecting pad 73 to move. This allows the limiting connecting pad 73 to drive the movable connecting column 74 to move, and the movable connecting column 74 to drive the assembly pad 76 and cast iron frame 77 fixedly connected to it to move. This allows the cast iron pad 78 on the outside of the cast iron frame 77 to fit against the outside of the corresponding plastic packaging box, thus limiting and positioning the outside of the plastic packaging box. It also ensures the stability of the plastic packaging box during the drying process, avoids the problem of the plastic packaging box being tilted, which affects the drying effect, and improves the drying effect of the plastic packaging box. This device is equipped with a closing connecting mechanism 6. The plastic packaging box conveyor belt 3 is used to transport the plastic packaging box, and the hot air drying device 4 can perform corresponding air drying. When the rotating door 5 needs to be opened for maintenance and repair of the internal components of the mounting bracket 1, the operator only needs to move the mounting positioning block 69 on the outside of the cast iron positioning column 62 to release the mounting positioning block 69 from the preset groove of the corresponding movable connecting pad 68, thus releasing the locking of the movable connecting pad 68. The blocking mounting pad 63 at one end of the cast iron positioning column 62 serves to limit the mounting positioning block 69. At the same time, after the movable connecting pad 68 is unlocked, the metal connecting handle 67 can be moved vertically to move the carbon steel connecting block 66 and the movable connecting pad 68, and to make the anti-disengagement slider 65 slide in the groove of the corresponding guide connecting sleeve 64. This can quickly release the lock of the cast iron outer shell 61 and make it easy to open the rotating door 5 for maintenance and repair of the internal components of the mounting bracket 1, which is beneficial for the maintenance of this device.
[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
