The body has a heat dissipation mechanism for cooling the lithium batteries after drying, and the operation box has a drive mechanism for operating the heat dissipation mechanism. The heat dissipation mechanism includes a heat dissipation box fixed to the body, with a mounting plate mounted on it. This invention forms a heat dissipation mechanism during the lithium battery drying process, quickly reducing the surface temperature of the lithium batteries after drying, allowing for direct subsequent processing and improving production efficiency. However, the device lacks a mechanism for efficiently collecting the dried lithium batteries, requiring workers to collect them again, reducing work efficiency.

[0004] Therefore, it is necessary to design a lithium battery production drying device that can efficiently collect the dried lithium batteries. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art where manual collection of dried lithium batteries is still required, resulting in low work efficiency, this utility model aims to provide a lithium battery production drying device that can efficiently collect dried lithium batteries.

[0006] To solve the above-mentioned technical problems, this utility model provides a lithium battery production drying device, including a base frame, a collection box, a feeding frame, a discharge drawer, a fan, a heating pipe, and a support rod. The collection box is slidably connected to one side of the lower part of the base frame, and several discharge drawers are slidably connected to one side of the base frame at even intervals. A feeding frame is provided on one side of the base frame in the width direction. Several heating pipes are connected to the side of the base frame opposite to the side with the discharge drawers. Fans are also symmetrically connected to the base frame on the same side as the heating pipes. The heating pipes are located between the fans and the discharge drawers. A support rod for fixing the fans is also connected between the fans and the base frame.

[0007] Preferably, it also includes an elastic element, a push rod, and a push plate. The push rod is connected to the top of the base frame. The push rod passes through the base frame and extends to the lowest material feeding drawer inside the base frame. The push rod is connected to a push plate near the material feeding drawer. The push plate passes through one side of the material feeding drawer along its length and contacts the inner bottom plate of the material feeding drawer. The push rod is connected to an elastic element on the side perpendicular to the push plate. The elastic element is connected to the inner wall of the feeding frame.

[0008] Preferably, it also includes speed reducers, with several speed reducers staggered on both sides of the symmetrical inner wall of the feeding frame.

[0009] Preferably, it also includes a first pull rod and a second pull rod, with the first pull rod connected to the outside of the collection box and the second pull rod connected to the outside of the material drawer.

[0010] Preferably, it also includes a ventilation plate, with a number of ventilation holes evenly spaced on the inner bottom plate of the material drawer, and ventilation plates connecting adjacent material drawers.

[0011] Preferably, it also includes a filter screen, with the filter screen disposed between the fan and the base frame.

[0012] Preferably, the speed reducer is provided with an inclined surface, and the inclined surfaces of adjacent speed reducers face downwards towards each other.

[0013] Preferably, the side of the material drawer closest to the feeding frame has a notch.

[0014] The beneficial effects of this utility model are as follows: heat is generated by the heating tube and transported to the discharge drawers of each layer by the fan, so that the lithium batteries can be dried quickly; the lithium batteries are quickly pushed to the side of the discharge drawer opening by the cooperation of the push rod and the push plate and fall onto the deceleration plate. After being decelerated and buffered by the deceleration plate, they fall into the collection box, thus efficiently completing the collection of lithium batteries. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, a lithium battery production drying device includes a base frame 1, a collection box 2, a first pull rod 3, a feeding frame 4, a discharge drawer 6, a second pull rod 7, a speed reducer 8, a ventilation plate 10, a fan 12, a heating pipe 13, and a support rod 14. The collection box 2 is slidably connected to the lower front side of the base frame 1, and the first pull rod 3 is connected to the front side of the collection box 2. Seven discharge drawers 6 are slidably connected to the front side of the base frame 1 at even intervals. The right side of the discharge drawer 6 has a notch, and the bottom plate inside the discharge drawer 6 has several ventilation holes 9 at even intervals. Ventilation plates 10 are connected between the material drawers 6. A second pull rod 7 is connected to the front of the material drawer 6. A feeding frame 4 is provided on the right side of the base frame 1. Several speed reduction plates 8 are arranged alternately on the inner wall of the right side of the feeding frame 4. The speed reduction plates 8 are set at an angle, and the angles of adjacent speed reduction plates 8 are set facing downwards. Several heating pipes 13 are connected to the rear side of the base frame 1. Fans 12 are also symmetrically connected to the rear side of the base frame 1. The heating pipes 13 are located between the fan 12 and the material drawer 6. A support rod 14 for fixing the fan 12 is also connected between the fan 12 and the base frame 1.

[0023] like Figure 4 As shown, it also includes an elastic element 401, a push rod 5, and a push plate 501. The push rod 5 is connected to the top of the base frame 1. The push rod 5 passes through the base frame 1 and extends to the lowest material drawer 6 inside the base frame 1. The push plate 501 is connected to the side of the push rod 5 near the material drawer 6. The push plate 501 passes through one side of the material drawer 6 along its length and contacts the inner bottom plate of the material drawer 6. The elastic element 401 is connected to the side of the push rod 5 perpendicular to the side with the push plate 501. The elastic element 401 is connected to the inner wall of the feeding frame 4.

[0024] When this device is needed to dry lithium batteries, the operator first pulls out the discharge drawer 6 forward and places the lithium batteries to be dried evenly and dispersed on the inner bottom plate of the discharge drawer 6. After the lithium batteries are placed, the discharge drawer 6 is reset. Then, the heating tube 13 is energized, generating heat. The fan 12 is then activated, blowing the heat generated by the heating tube 13 into the discharge drawer 6. The bottom plate of the discharge drawer 6 and the ventilation plate 10 can accelerate the heat exchange between the discharge drawers 6, and also allow the heat generated by the heating tube 13 to quickly reach the surface of the lithium batteries, accelerating the drying efficiency. After the lithium battery drying operation is completed, the operator turns off the heating tube 13 and the fan 12 in sequence. Then, the operator applies pressure to the push rod 5 to move it to the right. The push rod 5 drives the push plate 501 connected to it to move to the right. During the transfer process, the lithium batteries on the bottom plate of the discharge drawer 6 are pushed to the right side of the discharge drawer 6. The lithium batteries then fall onto the deceleration plate 8 through the notch on the right side of the discharge drawer 6. Since the deceleration plates 8 are arranged with staggered, downward-facing slopes, the lithium batteries fall onto the upper deceleration plate 8 and then slide down the slope towards the middle of the right inner wall of the feeding frame 4. They pass through the deceleration plates 8 on the right inner wall of the feeding frame 4 until they fall into the collection box 2 at the bottom. This avoids the lithium batteries from falling directly from a height and being damaged. As the push rod 5 moves to the right, it compresses and deforms the elastic element 401. When no force is applied to the push rod 5, the elastic element 401 returns to its original position. This causes the push rod 5 and the push plate 501 connected to the push rod 5 to move to the left and return to their original position. This achieves efficient collection of the dried lithium batteries. After collection, the collection box 2 is pulled forward by the first pull rod 3 to place the lithium batteries in the designated location.

[0025] Example 2

[0026] like Figure 3 As shown, based on Embodiment 1, a filter screen 11 is also included, and the filter screen 11 is disposed between the fan 12 and the base frame 1.

[0027] The filter 11 is designed to prevent debris from entering the fan 12 and affecting its normal operation.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
