Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: This embodiment specifically describes the structure of an environmentally friendly packaging box for lithium battery foil rolls, such as... Figures 1-4 As shown, it consists of three parts: a box, a trapezoidal block, and a roll material; Box 1, which is composed of a base 101, a side plate 104 and a top cover 105. A support block 102 is fixedly connected to the bottom end of the base 101. An installation groove 103 is provided inside the support block 102. A side plate 104 is fixedly connected to the top edge of the base 101. The top cover 105 is disposed on the top of the side plate 104. The trapezoidal block 2 is divided into an upper inner liner block 201 and a lower inner liner block 202. The upper inner liner block 201 and the lower inner liner block 202 are both grid structures and have the same shape. The upper inner liner block 201 is inverted and set at the top of the lower inner liner block 202. The bottom end of the lower inner liner block 202 is fixedly installed in the mounting groove 103. The roll material 3 has mounting holes 301 at the bottom of the upper inner liner block 201 and the top of the lower inner liner block 202, and both ends of the roll material 3 are fixedly installed in the mounting holes 301.

[0022] The entire process of installing the environmentally friendly packaging box is as follows: First, align the protruding part of the bottom of the lower inner liner 202 with the mounting groove 103 inside the support block 102 and put it in. At this time, the bottom of the lower inner liner 202 is located at the top of the base 101, and the protruding part of the bottom of the lower inner liner 202 fits in the mounting groove 103. Then, select a rubber pad 5 of appropriate thickness according to the size of both ends of the roll material 3 and install it in the fixing hole 4 so that both ends of the roll material 3 can be stably fixed in the mounting hole 301. Then, the limiting block 7 on the inverted upper inner liner 201 is engaged in the interlocking groove 6 opened at the top of the lower inner liner 202. Then, the slot 9 opened at the bottom of the top cover 105 is engaged in the top of the side plate 104. The engaged top cover 105 is then pressed downwards and vertically pressed against the upper inner liner 201.

[0023] In some examples, such as Figure 2 and Figure 3 As shown, both the lower inner liner block 202 and the mounting hole 301 are provided with fixing holes 4, and a rubber pad 5 is movably installed inside the fixing hole 4.

[0024] It is understandable that the rubber pad 5 can play a shock absorption role, and at the same time, the use of rubber pads 5 of different thicknesses can limit and fix the mounting holes 301 of different sizes in the mounting holes 301.

[0025] In some examples, such as Figure 3 As shown, the contact surfaces of the upper inner liner block 201 and the lower inner liner block 202 are provided with an interlocking structure; The interlocking structure includes an interlocking groove 6 formed on the top of the lower inner liner block 202, and a limiting block 7 fixedly connected to the bottom of the upper inner liner block 201, which engages with the interlocking groove 6.

[0026] It is understandable that the interlocking groove 6 and the limiting block 7 in the interlocking structure can prevent sliding when the upper inner liner block 201 and the lower inner liner block 202 are in contact.

[0027] In some examples, such as Figure 2 As shown, the base 101 has two pairs of symmetrically arranged long plates 8 inside its top end. The long plates 8 are made of metal and are fixedly connected to the side plates 104 on both sides in a vertical and parallel manner.

[0028] Understandably, the two pairs of metal plates 8 installed on the top of the base 101 can increase the overall strength of the box 1.

[0029] In some examples, such as Figure 4 As shown, the bottom end of the top cover 105 has a slot 9 that engages with the top end of the side plate 104.

[0030] Understandably, the slot 9 can further enhance the overall strength of the box 1, while also providing downward pressure to the upper inner liner block 201 to ensure that the trapezoidal block 2 is in vertical contact.

[0031] In some examples, such as Figure 1 As shown, the side plate 104 has handles 10 on both vertical parallel sides.

[0032] Understandably, the inclusion of the carrying block 10 facilitates the handling of the entire box 1 by mechanical grippers or similar devices.

[0033] The working principle of an environmentally friendly packaging box for lithium battery foil roll 3 in this application embodiment is as follows: First, place the protruding block at the bottom of the lower inner liner 202 into the mounting groove 103 inside the support block 102. Then, select a rubber pad 5 of appropriate thickness according to the size of both ends of the roll 3 and install it in the fixing hole 4. Next, place the roll 3 into the mounting hole 301 through the conveying device and position it at the top of the rubber pad 5. Then, engage the limiting block 7 on the inverted upper inner liner 201 into the interlocking groove 6 opened at the top of the lower inner liner 202. Finally, engage the slot 9 opened at the bottom of the top cover 105 into the top of the side plate 104 to complete the packing of the roll 3.
