Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and in particular to a waste trough for a winding process. Background Technology

[0002] In the production process of lithium-ion battery cells, the winding process is one of the key steps. The winding material is fed into the winding machine in the order of positive electrode sheet, separator, negative electrode sheet, and separator to form the main structure of the battery cell.

[0003] During the operation of the winding machine, the cut-off winding material becomes waste, which is sent to the waste trough for collection via a waste conveyor belt for subsequent processing.

[0004] Since the waste material usually falls at the same location in the waste trough, a pyramid-shaped accumulation will form inside the waste trough, making it difficult to fully utilize the upper space of the waste trough, resulting in the effective volume of the waste trough being much smaller than the actual volume. Utility Model Content

[0005] In order to improve the space utilization of the waste trough, this application provides a waste trough for the winding process.

[0006] The waste trough for the winding process provided in this application adopts the following technical solution:

[0007] A waste trough for a winding process includes a trough body with a recycling trough at the top. One end of the recycling trough is a feeding end, and the other end is a discharging end. A guide slope is provided on the bottom wall of the recycling trough, which slopes downward from the feeding end to the discharging end. A first material control component, a second material control component, and a third material control component are provided inside the recycling trough. The second material control component is located between the first and third material control components. The first material control component is located between the feeding end and the second material control component. The third material control component is located between the discharging end and the second material control component. All three material control components are used to control the distribution of waste material in the recycling trough.

[0008] By adopting the above technical solution, the waste material on the belt falls into the recycling tank from above the feeding end, and the waste material in the recycling tank slides down along the guide slope. At the same time, the first material control component, the second material control component and the third material control component control the distribution of the waste material in the recycling tank, so that the waste material is less likely to form a pyramid-shaped accumulation in the recycling tank, thereby improving the space utilization rate of the waste material tank.

[0009] Preferably, the recycling tank includes a first material tank, a second material tank, a third material tank, and a fourth material tank, which are connected in sequence. The first material tank is located between the first material control component and the inlet end, the second material tank is located between the first material control component and the second material control component, the third material tank is located between the second material control component and the third material control component, and the fourth material tank is located between the third material control component and the outlet end. The first and second material control components are used to ensure that the load-bearing weight in the second material tank is greater than the load-bearing weight in the first material tank, and the second and third material control components are used to ensure that the load-bearing weight in the third material tank is greater than the load-bearing weight in the second material tank.

[0010] By adopting the above technical solution, the waste material on the belt falls into the first material trough from above the feed end. The guide ramp causes the waste material in the first material trough to have a downward sliding tendency. When the weight of the waste material in the first material trough is less than the opening weight of the first material control component, the waste material in the first material trough is blocked by the first material control component and does not easily enter the second material trough. When the weight of the waste material in the first material trough exceeds the opening weight of the first material control component, the waste material in the first material trough forces the first material control component to open, thereby allowing the waste material to enter the second material trough from the first material trough. The guide ramp causes the waste material in the second material trough to have a downward sliding tendency. When the weight of the waste material in the second material trough is less than the opening weight of the second material control component, the waste material in the second material trough is blocked by the second material control component and does not easily enter the third material trough. When the weight of the waste in the trough exceeds the opening weight of the second material control component, the waste in the second trough forces the second material control component to open, allowing the waste to enter the third trough. The guide ramp causes the waste in the third trough to have a downward sliding tendency. When the weight of the waste in the third trough is less than the opening weight of the third material control component, the waste in the third trough is blocked by the third material control component and does not easily enter the fourth trough. When the weight of the waste in the third trough exceeds the opening weight of the third material control component, the waste in the third trough forces the third material control component to open, allowing the waste to enter the fourth trough. This achieves the effect of controlling the distribution of waste in the recycling trough, making it less likely for waste to form a pyramid-shaped accumulation in the recycling trough, and improving the space utilization rate of the waste trough.

[0011] Preferably, the first material control assembly includes a first baffle plate and a plurality of first elastic members. The first baffle plate is located between the first material trough and the second material trough. The first baffle plate is rotatably connected to the trough body. The first elastic members are located on the side of the first baffle plate facing the second material trough. One end of the first elastic member abuts against the first baffle plate, and the other end of the first elastic member is fixedly connected to the trough body. Both side walls of the first baffle plate are in contact with the inner side wall of the recycling trough. The bottom of the first baffle plate is used to contact the guide slope.

[0012] By adopting the above technical solution, when the force exerted by the waste material in the first material trough on the first baffle plate is less than the force exerted by the first elastic element on the first baffle plate, the first elastic element causes the bottom of the first baffle plate to fit against the guide slope. At this time, the waste material in the first material trough is blocked by the first baffle plate and does not easily enter the second material trough. When the force exerted by the waste material in the first material trough on the first baffle plate is greater than the force exerted by the first elastic element on the first baffle plate, the waste material in the first material trough forces the first baffle plate to rotate, causing the bottom of the first baffle plate to separate from the guide slope, thereby allowing the waste material to enter the second material trough from the first material trough.

[0013] Preferably, the second material control assembly includes a second baffle plate and a plurality of second elastic members. The second baffle plate is located between the second material trough and the third material trough. The second baffle plate is rotatably connected to the trough body. The second elastic members are located on the side of the second baffle plate facing the third material trough. One end of the second elastic member abuts against the second baffle plate, and the other end of the second elastic member is fixedly connected to the trough body. Both side walls of the second baffle plate are in contact with the inner side wall of the recycling trough. The bottom of the second baffle plate is used to contact the guide slope.

[0014] By adopting the above technical solution, when the force exerted by the waste material in the second material trough on the second baffle plate is less than the force exerted by the second elastic element on the second baffle plate, the second elastic element causes the bottom of the second baffle plate to fit against the guide slope. At this time, the waste material in the second material trough is blocked by the second baffle plate and does not easily enter the third material trough. When the force exerted by the waste material in the second material trough on the second baffle plate is greater than the force exerted by the second elastic element on the second baffle plate, the waste material in the second material trough forces the second baffle plate to rotate, causing the bottom of the second baffle plate to separate from the guide slope, thereby allowing the waste material to enter the third material trough from the second material trough.

[0015] Preferably, the third material control assembly includes a third baffle plate and several third elastic members. The third baffle plate is located between the third material trough and the fourth material trough. The third baffle plate is rotatably connected to the trough body. The third elastic members are located on the side of the third baffle plate facing the fourth material trough. One end of the third elastic member abuts against the third baffle plate, and the other end of the third elastic member is fixedly connected to the trough body. Both side walls of the third baffle plate are in contact with the inner side wall of the recycling trough. The bottom of the third baffle plate is used to contact the guide slope.

[0016] By adopting the above technical solution, when the force exerted by the waste material in the third material trough on the third baffle plate is less than the force exerted by the third elastic element on the third baffle plate, the third elastic element causes the bottom of the third baffle plate to fit against the guide slope. At this time, the waste material in the third material trough is blocked by the third baffle plate and does not easily enter the fourth material trough. When the force exerted by the waste material in the third material trough on the third baffle plate is greater than the force exerted by the third elastic element on the third baffle plate, the waste material in the third material trough forces the third baffle plate to rotate, causing the bottom of the third baffle plate to separate from the guide slope, thereby allowing the waste material to enter the fourth material trough from the third material trough.

[0017] Preferably, a first rotating shaft is provided through the first baffle plate and fixedly connected to the first baffle plate; a second rotating shaft is provided through the second baffle plate and fixedly connected to the second baffle plate; a third rotating shaft is provided through the third baffle plate and fixedly connected to the third baffle plate; the first, second, and third rotating shafts all penetrate the trough and are rotatably connected to the trough.

[0018] By adopting the above technical solution, the first baffle plate is rotatably connected to the tank body through the first rotating shaft, the second baffle plate is rotatably connected to the tank body through the second rotating shaft, and the third baffle plate is rotatably connected to the tank body through the third rotating shaft.

[0019] Preferably, the recycling tank is provided with a first mounting plate, a second mounting plate and a third mounting plate. The first mounting plate, the second mounting plate and the third mounting plate are all fixedly connected to the tank body. The end of the first elastic member away from the first baffle plate is fixedly connected to the first mounting plate. The end of the second elastic member away from the second baffle plate is fixedly connected to the second mounting plate.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a waste trough for a winding process. (Refer to...) Figure 1The system includes a tank body 1, with a recycling tank 2 at the top. The recycling tank 2 includes a first material tank 21, a second material tank 22, a third material tank 23, and a fourth material tank 24, which are connected sequentially. The end of the first material tank 21 furthest from the second material tank 22 is the inlet end 11, and the end of the fourth material tank 24 furthest from the third material tank 23 is the outlet end 12. A guide slope 3 is provided on the bottom wall of the recycling tank 2, sloping downwards from the inlet end 11 to the outlet end 12. The inclination angle of the guide slope 3 is... , and , To guide the friction coefficient of inclined plane 3, a first material control component 4 is installed between the first material trough 21 and the second material trough 22. The opening weight of the first material control component 4 is... A second material control component 5 is installed between the second material trough 22 and the third material trough 23. The opening weight of the second material control component 5 is... A third material control component 6 is installed between the third material trough 23 and the fourth material trough 24. The opening weight of the third material control component 6 is... The first material control assembly 4 and the second material control assembly 5 are used to ensure that the load-bearing weight in the second material trough 22 is greater than the load-bearing weight in the first material trough 21; the second material control assembly 5 and the third material control assembly 6 are used to ensure that the load-bearing weight in the third material trough 23 is greater than the load-bearing weight in the second material trough 22. Waste material on the belt 7 falls into the first material trough 21 from above the feed end 11, and the guide ramp 3 causes the waste material in the first material trough 21 to have a downward sliding tendency. When the weight of the waste material in the first material trough 21 is less than the opening weight of the first material control assembly 4, the waste material in the first material trough 21 is blocked by the first material control assembly 4 and does not easily enter the second material trough 22; when the weight of the waste material in the first material trough 21 exceeds the opening weight of the first material control assembly 4, the waste material in the first material trough 21 forces the first material control assembly 4 to open, thereby allowing the waste material to enter the second material trough 22 from the first material trough 21. The guide ramp 3 causes the waste material in the second feed trough 22 to tend to slide downwards. When the weight of the waste material in the second feed trough 22 is less than the opening weight of the second material control component 5, the waste material in the second feed trough 22 is blocked by the second material control component 5 and does not easily enter the third feed trough 23. When the weight of the waste material in the second feed trough 22 exceeds the opening weight of the second material control component 5, the waste material in the second feed trough 22 forces the second material control component 5 to open, thereby allowing the waste material to enter the third feed trough 23 from the second feed trough 22. The guide ramp 3 causes the waste material in the third feed trough 23 to tend to slide downwards. When the weight of the waste material in the third feed trough 23 is less than the opening weight of the third material control component 6, the waste material in the third feed trough 23 is blocked by the third material control component 6 and does not easily enter the fourth feed trough 24. When the weight of the waste material in the third feed trough 23 exceeds the opening weight of the third material control component 6, the waste material in the third feed trough 23 forces the third material control component 6 to open, thereby allowing the waste material to enter the fourth feed trough 24 from the third feed trough 23. This achieves the effect of controlling the distribution of waste in the recycling tank 2, making it less likely for waste to form a pyramid-shaped accumulation, and improving the space utilization rate of the waste tank.

[0035] Reference Figure 1 and Figure 2The first material control assembly 4 includes a first baffle plate 41 and several first elastic elements 42. The first baffle plate 41 is located between the first material trough 21 and the second material trough 22. A first rotating shaft 411 is disposed through the first baffle plate 41 and welded to the first baffle plate 41. The first rotating shaft 411 passes through the trough body 1 and is rotatably connected to the trough body 1. The first elastic elements 42 are V-shaped spring sheets. The first elastic elements 42 are located on the side of the first baffle plate 41 facing the second material trough 22 and abut against the first baffle plate 41. The first elastic elements 42 are connected to a first mounting plate 421 by bolts. The first mounting plate 421 is welded to the trough body 1. Both side walls of the first baffle plate 41 are in contact with the inner side wall of the recycling trough 2, and the bottom of the first baffle plate 41 is used to contact the guide slope 3. When the force exerted by the waste material in the first feed trough 21 on the first baffle plate 41 is less than the force exerted by the first elastic member 42 on the first baffle plate 41, the first elastic member 42 causes the bottom of the first baffle plate 41 to fit against the guide slope 3. At this time, the waste material in the first feed trough 21 is blocked by the first baffle plate 41 and does not easily enter the second feed trough 22. When the force exerted by the waste material in the first feed trough 21 on the first baffle plate 41 is greater than the force exerted by the first elastic member 42 on the first baffle plate 41, the waste material in the first feed trough 21 forces the first baffle plate 41 to rotate, causing the bottom of the first baffle plate 41 to separate from the guide slope 3, thereby allowing the waste material to enter the second feed trough 22 from the first feed trough 21.

[0036] Reference Figure 1 and Figure 3The second material control assembly 5 includes a second baffle plate 51 and several second elastic elements 52. The second baffle plate 51 is located between the second material trough 22 and the third material trough 23. A second rotating shaft 511 is disposed through the second baffle plate 51 and welded to the second baffle plate 51. The second rotating shaft 511 passes through the trough body 1 and is rotatably connected to the trough body 1. The second elastic elements 52 are V-shaped spring sheets. The second elastic elements 52 are located on the side of the second baffle plate 51 facing the third material trough 23 and abut against the second baffle plate 51. The second elastic elements 52 are connected to a second mounting plate 521 by bolts. The second mounting plate 521 is welded to the trough body 1. Both side walls of the second baffle plate 51 are in contact with the inner side wall of the recycling trough 2, and the bottom of the second baffle plate 51 is used to contact the guide slope 3. When the force exerted by the waste material in the second feed trough 22 on the second baffle plate 51 is less than the force exerted by the second elastic element 52 on the second baffle plate 51, the second elastic element 52 causes the bottom of the second baffle plate 51 to fit against the guide slope 3. At this time, the waste material in the second feed trough 22 is blocked by the second baffle plate 51 and does not easily enter the third feed trough 23. When the force exerted by the waste material in the second feed trough 22 on the second baffle plate 51 is greater than the force exerted by the second elastic element 52 on the second baffle plate 51, the waste material in the second feed trough 22 forces the second baffle plate 51 to rotate, causing the bottom of the second baffle plate 51 to separate from the guide slope 3, thereby allowing the waste material to enter the third feed trough 23 from the second feed trough 22.

[0037] Reference Figure 1 and Figure 4The third material control assembly 6 includes a third baffle plate 61 and several third elastic elements 62. The third baffle plate 61 is located between the third material trough 23 and the fourth material trough 24. A third rotating shaft 611 is installed through the third baffle plate 61 and welded to it. The third rotating shaft 611 passes through the trough body 1 and is rotatably connected to it. The third elastic elements 62 are V-shaped spring sheets. The third elastic elements 62 are located on the side of the third baffle plate 61 facing the fourth material trough 24 and abut against the third baffle plate 61. The third elastic elements 62 are connected to a third mounting plate 621 by bolts. The third mounting plate 621 is welded to the trough body 1. Both side walls of the third baffle plate 61 are in contact with the inner side wall of the recycling trough 2, and the bottom of the third baffle plate 61 is used to contact the guide slope 3. When the force exerted by the waste material in the third feed trough 23 on the third baffle plate 61 is less than the force exerted by the third elastic member 62 on the third baffle plate 61, the third elastic member 62 causes the bottom of the third baffle plate 61 to fit against the guide slope 3. At this time, the waste material in the third feed trough 23 is blocked by the third baffle plate 61 and does not easily enter the fourth feed trough 24. When the force exerted by the waste material in the third feed trough 23 on the third baffle plate 61 is greater than the force exerted by the third elastic member 62 on the third baffle plate 61, the waste material in the third feed trough 23 forces the third baffle plate 61 to rotate, causing the bottom of the third baffle plate 61 to separate from the guide slope 3, thereby allowing the waste material to enter the fourth feed trough 24 from the third feed trough 23.

[0038] Reference Figures 1 to 4 The number of third elastic elements 62 is greater than the number of second elastic elements 52, and the number of second elastic elements 52 is greater than the number of first elastic elements 42. This makes the load-bearing weight in the second material trough 22 greater than the load-bearing weight in the first material trough 21, and the load-bearing weight in the third material trough 23 greater than the load-bearing weight in the second material trough 22.

[0039] Reference Figures 1 to 4 The distance between the first baffle plate 41 and the second baffle plate 51 is The distance between the second baffle plate 51 and the third baffle plate 61 is , , The belt speed is 7.

[0040] The implementation principle of a waste trough for a winding process in this application embodiment is as follows: the waste material on the belt 7 falls into the first trough 21 from above the feed end 11. When the weight of the waste material acting on the first baffle plate 41 exceeds the limit... When the first baffle plate 41 rotates, a gap appears between the bottom of the first baffle plate 41 and the guide slope 3, allowing the waste material in the first material trough 21 to pass through the gap and enter the second material trough 22. When the weight of the waste material acting on the second baffle plate 51 exceeds... At this time, the second baffle plate 51 rotates, creating a gap between the bottom end of the second baffle plate 51 and the guide slope 3, allowing the waste material in the second material trough 22 to pass through the gap and enter the third material trough 23. When the weight of the waste material acting on the third baffle plate 61 exceeds... At this time, the third baffle plate 61 rotates, creating a gap between the bottom of the third baffle plate 61 and the guide slope 3, allowing the waste in the third material trough 23 to pass through the gap and enter the fourth material trough 24. This achieves the effect of controlling the distribution of waste in the recycling trough 2, preventing the waste from forming a pyramid-shaped accumulation in the recycling trough 2, and improving the space utilization rate of the waste trough.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
