Description

Technical Field

[0001] The invention relates to the technical field related to material conveying and unloading, and in particular to a sagger continuous turning and unloading device. Background Art

[0002] A common positive electrode material used in lithium-ion batteries is lithium iron phosphate. The production of lithium iron phosphate requires processes such as mixing, grinding, drying, crushing, and sintering. The sintering process is to sinter and activate the raw materials crushed into granules in a tunnel furnace. The tunnel furnace has an opening at the position where sintering is completed. A roller conveyor is usually set outside the opening. The roller conveyor can carry out bidirectional transportation. After the material in the sagger transported from the roller conveyor is poured into the storage box, the empty sagger is put back on the roller conveyor and transported back to the tunnel furnace.

[0003] In some processes, manual unloading is performed manually, which consumes a lot of physical strength. Although workers wear heat-insulating gloves, there are still safety hazards if the sagger accidentally slips. In other processes, some automated equipment such as lifting mechanisms, clamping mechanisms, and rotating mechanisms are used to unload the sagger. However, since the sagger is generally covered with a cover, it is still necessary to remove the cover before unloading. Moreover, these devices are usually more complicated, resulting in a higher failure rate. When unloading, the sagger must first be lifted to a higher position, and then during the rotation process, the material is easy to overflow from both sides of the feed port of the storage box, resulting in the loss of sintered materials and causing more pollution in the workshop. Summary of the Invention

[0004] In view of the above-mentioned defects, the present invention provides a sagger continuous turning and unloading device, which can automatically turn over and unload the sagger, automatically turn over and put the sagger back, and can operate on multiple saggers continuously.

DETAILED DESCRIPTION

[0033] The present application will be further described below with reference to the accompanying drawings and examples.

[0034] like Figures 1 to 11 The device shown is a continuous flipping and unloading device for saggers, which is arranged at the outer end of the conveying end of a roller conveyor 6. The roller conveyor 6 is used to convey saggers 4. A cover plate 5 is placed on the top of the conveyed saggers 4. The device includes a flipping unit 1, a driving unit 2, and a cover pushing unit 3.

[0035] like Figures 1 to 9 As shown, the flip unit 1 includes a rotating motor 11, and a roller 12 is provided at its output end. Specifically, a first bracket 13 is provided at the lower end of the rotating motor 11. The flip unit 1 also includes a rotating seat 14. One end of the roller 12 is rotatably matched with the rotating seat 14. A connecting plate 15 is provided at one end of the outer peripheral side of the roller 12. A baffle 16 is provided at one end of the connecting plate 15. A bottom supporting plate 17 is provided at one end of the baffle 16, and a top supporting plate 18 is provided at the other end. When the baffle 16 is in a vertical state and located above the roller 12, the bottom supporting plate 17 The highest point of the roller of the roller conveyor 6 is located at the same horizontal plane. Therefore, when the turning unit 1 is receiving the sagger 4, when the sagger 4 is conveyed to one end face and abuts against the baffle 16, the upper end face of the bottom supporting plate 17 abuts against the lower end face of the sagger 4, and the lower end face of the top supporting plate 18 abuts against the upper end face of the cover plate 5 on the sagger 4. The length of the bottom supporting plate 17 is greater than that of the top supporting plate 18, which makes it easier for the bottom supporting plate 17 to stably support the sagger 4 from its end, and the top supporting plate 18 to less block the material when pouring.

[0036] like Figures 1 to 10As shown, the number of drive units 2 is a pair, and they are mirror-imaged. The drive units 2 are respectively arranged on both sides of the baffle 16. The drive unit 2 includes a rotating plate 21 fixed to one end of the outer peripheral side of the rotating roller 12. The upper end surface of the rotating plate 21 is provided with an inverted L-shaped frame 211. The horizontal end of the inverted L-shaped frame 211 is provided with a first linear mechanism 22, and its output end is provided with a vertical L-shaped plate 23. The upper end surface of the vertical L-shaped plate 23 extends inward along its L-shaped profile with a horizontal L-shaped plate 231. The upper end surface of the rotating plate 21 is also provided with a second linear mechanism 24 located on one side of the vertical side of the inverted L-shaped frame 211, and its sliding end is provided with a third linear mechanism The first linear mechanism 22 and the third linear mechanism 25 are both parallel to the output axis of the rotary motor 11. A C-type clamp 26 is provided at the output end of the third linear mechanism 25. The C-type clamp 26 includes a long side and two parallel short sides. The inner side surface of the long side of the C-type clamp 26 is used to abut against the side surface of the sagger 4 so as to clamp the sagger 4. The two short sides of the C-type clamp 26 are respectively used to abut against the two end surfaces of the sagger 4 when clamping. A cover block 27 is further extended from the upper end of the short side closer to the rotating roller 12.

[0037] like Figures 1 to 8 、 Figure 11 As shown, the cover pushing unit 3 is arranged below a driving unit 2, and includes a fourth linear mechanism 31 whose output direction is parallel to the sliding direction of the second linear mechanism 24, and a plurality of second brackets 32 are provided at the lower end thereof. A push plate 33 is provided at the output end of the fourth linear mechanism 31, and a cross bar 34 is provided at one end of the push plate 33. A pair of triangular blocks 35 with a right-angled triangle cross section are provided on one side of the cross bar 34. The vertical surface of the triangular block 35 is used to push the cover plate 5 when the sagger 4 is flipped to a state where the opening is facing downward. The inclined surface of the triangular block 35 is used to make the material fall, and the inclined surface is facing the direction of the roller conveyor 6.

[0038] In this embodiment, the first linear mechanism 22 , the third linear mechanism 25 , and the fourth linear mechanism 31 all adopt linear hydraulic cylinders, and the second linear mechanism 24 adopts a rodless linear cylinder or an electric slide rail.

[0039] Working method:

[0040] First, if Figure 1 As shown, the first sagger 4 is transported from the upper right corner to the lower left of the picture. Of course, before this, the vertical L-shaped plate 23 and the horizontal L-shaped plate 231 need to be retracted by the first linear mechanism 22 so that the sagger 4 can be normally transported to the conveying end of the roller conveyor 6. Figure 1 The figure shows a state where the sagger 4 is about to contact the baffle 16. After the contact, the third linear mechanism 25 is moved by the second linear mechanism 24, and the C-shaped clamp 26 is clamped on the side of the sagger 4 by the third linear mechanism 25. The vertical L-shaped plate 23 is limited from the top of the sagger 4 and the cover plate 5 by the first linear mechanism 22.

[0041] Then, the motor 11 is rotated 180 degrees so that the state is as follows: Figure 2 As shown, the first sagger 4 and its matching cover 5 are located below. More specifically, a storage box is placed on the ground below the sagger 4 before this. Figure 2 It can be seen in FIG. 4 that the second sagger 4 is now ready for transport and is already prepared at the transport end of the roller conveyor 6 .

[0042] Then, the fourth linear mechanism 31 is used to make the triangular block 35 push the cover plate 5. During this process, the material in the sagger 4 falls into the storage box. Specifically, the triangular block 35 passes through both sides of the top supporting plate 18 without being blocked. When pushing, the vertical L-shaped plate 23 and the horizontal L-shaped plate 231 are located below and used as a set of limiting slides. The cover plate 5 is finally pushed to the intersection of the long side and the short side of the vertical L-shaped plate 23, which is also the intersection of the long side and the short side of the inner side of the horizontal L-shaped plate 231, that is, Figure 3 and Figure 4 The status shown.

[0043] Then, since the C-shaped clamp 26 clamps the side of the sagger 4, the sagger 4 is slid by the second linear mechanism 24 and is finally pushed to the position as shown in FIG. Figure 5 and Figure 6 The state shown in FIG. 2 is shown in FIG. 2 , and the stopper block 27 is against the cover plate 5 at this time. Since the cover plate 5 will pass through a vertical state during the subsequent rotation process, this can prevent it from sliding down.

[0044] Next, the sagger 4 and the cover plate 5 that have been emptied of the material are rotated back to the roller conveyor 6 in their original matching form by the rotating motor 11, forming a Figure 7 After this, in Figure 8 Before the state of turning over, two actions need to be performed. One is to convert the clamping of the empty sagger 4 by the C-shaped clamp 26 into clamping the sagger 4 to be turned over by the second linear mechanism 24 and the third linear mechanism 25, and the other is to retract the vertical L-shaped plate 23 and the horizontal L-shaped plate 231 and return the empty sagger 4 to the tunnel furnace through the roller conveyor 6.

[0045] Eventually, it will form Figure 8 state, and then operate on the next sagger 4 and its cover plate 5 by analogy.

[0046] The above are only some of the embodiments listed in this application and are not intended to limit this application.
