Through setting up the elasticity subassembly that resets for when last box was opened, but the sealed drying box of closing plate automatic re-setting avoids the drier to consume fast.

Referring to fig. 3 and 4, preferably, the link swing reset mechanism 7 includes a first mounting seat 7a fixed in the lower case 2, two hinge seats 7b are symmetrically disposed on the first mounting seat 7a, and each hinge seat 7b is formed by two hinge vertical plates disposed in parallel and at an interval.

The upper end proximal ends of the two matched hinged vertical plates are hinged with a swinging component 7c, and the upper end proximal ends of the swinging components 7c are hinged with the linkage rod 5; a guide strip 7d matched with the lower end of the swinging component 7c is arranged on the first mounting seat 7a between the two hinged vertical plates matched with each other, and the lower end of the swinging component 7c moves along the guide strip 7 d.

The guide strip 7d is composed of a horizontal positioning section 7e arranged on the first mounting seat 7a between the two matched hinged vertical plates, arc-shaped guide sections 7f which are symmetrical and integrally formed at two ends of the horizontal positioning section 7e, and limiting blocks 7g arranged at free ends of the arc-shaped guide sections 7 f; each arc-shaped guide section 7f is obliquely arranged upward. The design of the horizontal positioning section aims to keep the linkage rod in a static state when the linkage rod is not extruded by a copper foil roll, and the problem that the drying box is opened due to inertial swing of the linkage rod is avoided.

In an initial state, the swinging component 7c is kept in a vertical state under the guiding action of the horizontal positioning section 7e, and when the linkage rod 5 is displaced horizontally, the lower end of the swinging component 7c rotates along the corresponding arc-shaped guiding section 7 f.

Further preferably, the swing assembly 7c comprises a connecting rod 7h hinged to the hinged vertical plate, the upper end of the connecting rod 7h is hinged to the linkage rod 5, a second mounting seat 7i perpendicular to the connecting rod 7h is arranged at the lower end of the connecting rod 7h, guide rods 7j are movably arranged on the second mounting seats 7i on two sides of the connecting rod 7h in a penetrating mode respectively, a limiting seat 7k is fixedly connected between the lower ends of the guide rods 7j, and a plurality of second guide wheels 7l are arranged at the bottom of the limiting seat 7k in the horizontal direction.

A third return spring 7m is sleeved on the periphery of the guide rod 7j between the limiting seat 7k and the second mounting seat 7 i; when the connecting rod 7h is perpendicular to the linkage rod 5, the limiting seat 7k is positioned in the horizontal positioning section 7 e. The design of the second guide wheel is matched with the structure of the guide strip, so that the stability of the linkage rod in a static state is further ensured, and the linkage rod can move smoothly when swinging.

As shown in fig. 10 and 11, it is further preferable that the proximal end portions of the left and right ends of the upper end surface of the linkage rod 5 are integrally formed with guide bosses 5b, and the opposite side surfaces of the two guide bosses 5b are guide inclined surfaces 5c which smoothly transition from the upper end surface of the linkage rod 5;

each guide inclined plane 5c is positioned in one side of the corresponding lower positioning notch 2a far away from the other lower positioning notch 2a, and when a paper tube at the end part of the copper foil roll enters the lower positioning notch 2a, the paper tube extrudes the guide inclined plane 5c to enable the linkage rod 5 to horizontally displace. By arranging the guide inclined plane, when the supporting pipe at the end part of the copper foil contacts the guide inclined plane, the linkage rod is guided to displace, and the problem of unsmooth displacement caused by the fact that the linkage rod is perpendicular to the connecting part of the linkage swing reset mechanism in the initial state can be avoided.

When in use, the drying agent is firstly put into a drying box. Then the copper foil is wound into the lower box body, and the upper box body is covered, so that the drying agent can be exposed. And when the copper foil coil is taken out, the sealing plate is reset to enable the drying box to be in a closed sealing state. When the box body is covered, the linkage rod does not displace, the limiting rod penetrates through the limiting hole, and the drying box is still in a sealed state. The utilization rate of the drying agent is further improved, and unnecessary waste is avoided.
