[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] According to one embodiment of this application, a feeding device is provided. For example... Figures 1 to 4 As shown, the feeding device includes a first guide rail 1, a first sliding member 3, and a feeding mechanism 2. The first guide rail 1 is arranged along a first direction. The first sliding member 3 is slidably disposed on the first guide rail 1. The feeding mechanism 2 includes a hopper 21, which is suitable for storing powder. The feeding mechanism 2 is disposed on the first sliding member 3. The first sliding member 3 can drive the feeding mechanism 2 to slide along the first guide rail 1, and the feeding mechanism 2 can move along the first sliding member 3 in a second direction to adjust the position of the feeding mechanism 2.

[0035] In this example, the feeding mechanism 2 is equipped with a hopper 21, which is used for storing and feeding materials. The feeding mechanism 2 can slide along the first guide rail 1, thereby adjusting the position of the feeding mechanism 2. The position adjustment of the feeding mechanism 2 is more convenient, which facilitates the maintenance, assembly or disassembly of the roller 20 below the feeding mechanism 2.

[0036] The hopper 21 can be used to store powder, for example, dry powder used to prepare dry electrodes. A discharge port is provided at the lower end of the hopper 21, and a roller 20 is positioned below the discharge port. The powder flows from the discharge port to the roller 20. The rollers 20 are arranged in pairs, with a gap between them, allowing the powder to flow into the gap. The rotation of the rollers 20 presses the powder into a film. The feeding mechanism 2 can slide along the first guide rail 1, that is, it can drive the hopper 21 to slide along the first guide rail 1 to adjust the position of the hopper 21, thereby avoiding the roller 20 below.

[0037] like Figure 1 As shown, in this example, the feeding device includes a mounting base 22, and a hopper 21 is mounted on the mounting base 22. The mounting base 22 is slidably disposed on the first guide rail 1, thereby driving the hopper 21 to slide along the first guide rail 1 to adjust the position of the hopper 21.

[0038] like Figure 2 As shown, in this example, the first guide rail 1 can be horizontally positioned and extend along the second direction. The feeding mechanism 2 slides along the first guide rail 1, that is, the feeding mechanism 2 slides along the second direction, thereby moving away from the roller 20. The first guide rail 1 is mounted on the fixed base 10, and then the fixed base 10 is fixedly mounted on the frame. The fixed base 10 can be a structure such as a mounting plate, and the first guide rail 1 is fixedly mounted to the fixed base 10 by fasteners such as screws or bolts. Alternatively, the first guide rail 1 can also be directly mounted on the frame. Those skilled in the art can determine the specific configuration based on the actual situation, and no specific limitations are made here.

[0039] like Figure 1 and Figure 2 As shown, in this example, two first guide rails 1 can be spaced apart, for example, two first guide rails 1 can be spaced apart along a first direction. The first direction can be horizontal. The opposite sides of the feeding mechanism 2 can be slidably mounted on the first guide rails 1, thereby improving the smoothness and stability of the feeding mechanism 2 sliding along the first guide rails 1. The hopper 21 can be located between the two first guide rails 1.

[0040] like Figure 1 and Figure 2As shown, in this example, the feeding device further includes a first sliding member 3, which is slidably disposed on the first guide rail 1. The feeding mechanism 2 is disposed on the first sliding member 3. The first sliding member 3 can drive the feeding mechanism 2 to slide along the first guide rail 1, and the feeding mechanism 2 can move on the first sliding member 3 in a second direction.

[0041] like Figure 1 and Figure 2 As shown, in this example, the first sliding member 3 is slidably mounted on the first guide rail 1, and the feeding mechanism 2 is connected to the first sliding member 3, that is, the mounting base 22 is connected to the first sliding member 3. The feeding mechanism 2 can thus slide along the first guide rail 1 via the first sliding member 3.

[0042] like Figure 1 As shown, the feeding mechanism 2 can also move along a second direction on the first sliding member 3. The second direction and the first direction can intersect. The second direction can be vertical, meaning the feeding mechanism 2 can slide upwards or downwards on the first sliding member 3. When adjustment of the rolls 20 is required, for example, adjusting the roll gap between the two rolls 20, the feeding mechanism 2 is moved upwards to move away from the rolls 20, thereby avoiding the rolls 20 and facilitating adjustment of the lower roll 20.

[0043] The second direction can be vertical or inclined relative to the vertical direction. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0044] like Figure 1 As shown, in this example, the mounting base 22 is also provided with a handle 221 to facilitate the lifting and disassembly of the unloading mechanism 2. Multiple handles 221 can be provided; for example, one can be provided on each of opposite sides, or more handles 221 can be provided. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0045] In one example, such as Figure 1 As shown, the first sliding member 3 is provided with a guide groove 31 along the second direction, and the feeding mechanism 2 can slide in the guide groove 31 or slide out of the guide groove 31.

[0046] like Figure 1 As shown, in this example, the mounting base 22 of the feeding mechanism 2 is provided with a sliding part 222 that cooperates with the guide groove 31. That is, the sliding part 222 can be engaged in the guide groove 31 and can slide along the guide groove 31. The guide groove 31 is arranged in the second direction, thereby enabling the feeding mechanism 2 to slide in the second direction.

[0047] In this example, the guide groove 31 has an opening at one end along the second direction. For example, the upper end of the guide groove 31 has an opening, and the sliding part 222 can slide out of the guide groove 31 through the opening, so that the unloading mechanism 2 can be disengaged from the guide groove 31 for easy maintenance. During assembly, the sliding part 222 is simply inserted into the guide groove 31 through the opening, making assembly simple.

[0048] The guide groove 31 has a support plate at the end away from the opening to support the sliding part 222. The sliding part 222 can fall on the support plate under the action of gravity, and the hopper 21 can reach the preset position, so as to facilitate accurate material feeding.

[0049] like Figure 2 As shown, in this example, two first guide rails 1 spaced apart along the first direction are each provided with a first sliding member 3, and sliding parts 222 are respectively provided on opposite sides of the mounting base 22.

[0050] In one example, such as Figure 1 As shown, the feeding device also includes a positioning pin 4. The guide groove 31 is provided with a positioning hole 32, through which the positioning pin 4 passes through the feeding mechanism 2 and the positioning hole 32 to position the feeding mechanism 2 in the guide groove 31.

[0051] like Figure 1 As shown, in this example, the bottom wall of the guide groove 31 is provided with a positioning hole 32. After the unloading mechanism 2 slides along the guide groove 31 to a preset position, one end of the positioning pin 4 can pass through the unloading mechanism 2 and be inserted into the positioning hole 32, thereby positioning the unloading mechanism 2.

[0052] For example, a positioning pin 4 is inserted into the sliding part 222 of the mounting base 22. After the sliding part 222 slides upward along the guide groove 31 to a preset position, it pushes the positioning pin 4 into the positioning hole 32, thereby positioning the feeding mechanism 2. After the positioning pin 4 is pulled out from the positioning hole 32, the sliding part 222 moves downward to the support plate at the lower end of the guide groove 31 under the action of gravity.

[0053] like Figure 1 As shown, in this example, positioning holes 32 are provided in the guide grooves 31 on both sides of the first sliding member 3. Positioning pins 4 are respectively provided on the sliding parts 222 on both sides of the mounting base 22.

[0054] In this example, multiple positioning holes 32 can be spaced apart along the second direction within the guide groove 31, thereby enabling the unloading mechanism 2 to be positioned at the corresponding location according to actual needs. For example, two, three, or four holes can be provided. Those skilled in the art can determine this based on the actual situation, and no specific limitation is made here.

[0055] In one example, the hopper 21 has a discharge port, the size of which is adjustable. The upper end of the hopper 21 has a feed inlet for feeding. The lower end of the hopper 21 has a discharge port for discharging. The size of the discharge port is adjustable; that is, the length or width of the discharge port can be adjusted to control the amount of powder discharged, thereby ensuring the continuity and uniformity of the discharge.

[0056] In one example, such as Figure 1 As shown, the hopper 21 includes a movable plate 211 and a fixed plate 212, which surround the hopper 21. One end of the movable plate 211 and the fixed plate 212 can form the discharge port. The movable plate 211 can move relative to the fixed plate 212 to adjust the size of the discharge port.

[0057] like Figure 1 As shown, in this example, the hopper 21 is formed by a fixed plate 212 and a movable plate 211 surrounding it. Both the upper and lower ends of the movable plate 211 and the fixed plate 212 have openings; the lower opening is a discharge port, and the upper opening is a feed port. The movable plate 211 can move relative to the fixed plate 212, thereby adjusting the size of the discharge port. For example, if the length of the discharge port is set along a first direction, the movable plate 211 can move along this first direction, thus adjusting the length of the discharge port.

[0058] like Figure 1 and Figure 2 As shown, in this example, multiple movable plates 211 and fixed plates 212 can be provided respectively. For example, two movable plates 211 are spaced apart along the first direction, and two fixed plates 212 are spaced apart along the second direction. The four plates surround to form the hopper 21, and the two movable plates 211 can move along the first direction respectively, thereby adjusting the size of the discharge port.

[0059] In this example, the size of the discharge port can also be adjusted by setting a baffle at the discharge port. That is, the baffle is movably set at the discharge port, and the baffle can block part of the discharge port. By moving the baffle, the size of the discharge port can be adjusted.

[0060] In one example, such as Figure 1 and Figure 2 As shown, the feeding device also includes a second guide rail 5, which has a scale along its length, and the movable plate 211 can slide along the second guide rail 5.

[0061] like Figure 1 and Figure 2As shown, in this example, the second guide rail 5 is mounted on the mounting base 22, and a second sliding member 213 is slidably disposed on the second guide rail 5. One side of the movable plate 211 is connected to the second sliding member 213, thereby enabling it to be slidably connected to the second guide rail 5. A scale is also provided on the surface of the second guide rail 5. When the movable plate 211 is pushed to move, the distance moved by the movable plate 211 can be determined according to the scale, thereby improving the accuracy of adjusting the feed opening size. The second guide rail 5 can be arranged along a first direction so that the movable plate 211 can slide along the second guide rail 5 in the first direction.

[0062] In this example, a sliding bearing is provided inside the second sliding member 213, and the second sliding member 213 is slidably connected to the second guide rail 5 through the sliding bearing, thereby improving the smoothness of the movement of the movable plate 211.

[0063] like Figure 1 As shown, in this example, the second sliding member 213 is also provided with a locking member 214. When the movable plate 211 moves to the preset position, the second sliding member 213 can be locked by the locking member 214 to fix the position of the movable plate 211. The locking member 214 can be a locking screw or other structure, which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0064] In one example, such as Figures 1 to 4 As shown, the feeding mechanism 2 also includes a rotating shaft 7. The hopper 21 has a feeding port. The rotating shaft 7 is disposed at the feeding port. The rotating shaft 7 can rotate to discharge the powder in the hopper 21 from the feeding port.

[0065] like Figures 1 to 4 As shown, the rotating shaft 7 is located at the discharge port. The rotation of the rotating shaft 7 can smoothly and continuously discharge the powder in the hopper 21 from the discharge port, which can avoid the powder from being blocked at the discharge port or the material falling intermittently.

[0066] In this example, the feeding device also includes a drive component 8, which is connected to the rotating shaft 7 to drive the rotating shaft 7 to rotate. The drive component 8 can be mounted on the mounting base 22 by means of fasteners such as screwing, snapping, or welding. Both ends of the rotating shaft 7 are rotatably mounted on the mounting base 22, and the drive component 8 can drive the rotating shaft 7 to rotate at a uniform speed. For example, the drive component 8 can be a rotary motor or other rotary drive mechanism. The rotary motor is connected to the rotating shaft 7 via a belt or chain 9 and can drive the rotating shaft 7 to rotate.

[0067] In one example, the sidewall of the rotating shaft 7 is provided with teeth along the circumference. The outer circumference of the rotating shaft 7 is provided with teeth, that is, the rotating shaft 7 has a gear structure. The rotating shaft 7 can block the feed port, the driving component 8 drives the rotating shaft 7 to rotate at a constant speed, and the teeth can drive the powder in the hopper 21 to flow out from the feed port, and can provide a metered feed.

[0068] In this example, the lower end of the movable plate 211 is bent to mate with the outer surface of the rotating shaft 7. The movable plate 211 is capable of moving along the length of the rotating shaft 7.

[0069] In one example, such as Figure 4 As shown, the feeding device also includes a baffle plate 6, which is located below the feeding port. There are two baffle plates 6, which can be movably arranged relative to each other. The baffle plates 6 are suitable for forming a buffer area with the side wall of the roll 20.

[0070] like Figure 4 As shown, in this example, the baffle plate 6 is located below the feed inlet. Two rollers 20 are spaced apart, with a gap between them. The baffle plate 6 is positioned between the two rollers 20, spaced apart along the length of each roller, and forms a buffer zone with the surfaces of the two rollers 20. Powder falling from the feed inlet can enter the buffer zone before entering the gap, where it is rolled into a film. By setting the buffer zone, the powder accumulation height can be ensured, thereby improving the film forming quality. The baffle plate 6 can be fixedly installed on the bearing seat of one of the rollers 20 and can move with the roller 20, reducing manual operation during gap adjustment.

[0071] In this example, the two baffles 6 can move relative to each other, that is, the two baffles 6 can move along the axial direction of the roll 20, thereby adjusting the length of the powder that can enter the roll gap, so as to adjust the width of the film after the powder is pressed into a film.

[0072] In one example, the distance between the two baffle plates 6 is greater than the length of the discharge port. That is, the distance between the two baffle plates 6 along the axial direction of the roller 20 is greater than the length of the discharge port, or in other words, the two movable plates 211 of the hopper 21 are located between the two baffle plates 6 to ensure that the powder falling into the buffer area is slightly higher in the middle and slightly lower on both sides, thereby controlling edge accumulation and avoiding the phenomenon that the film is thicker on both sides and thinner in the middle after film formation.

[0073] According to another embodiment of the present invention, an electrode production device is provided. This electrode production device includes the feeding device described in the above embodiment. The electrode production device can be used to produce dry electrodes. The feeding device includes a first guide rail 1 and a feeding mechanism 2. The feeding mechanism 2 includes a hopper 21 suitable for storing powder. The feeding mechanism 2 can slide along the first guide rail 1, thereby allowing adjustment of its position. This position adjustment facilitates maintenance, assembly, or disassembly of the roller 20 below the feeding mechanism 2.

[0074] In this example, multiple feeding devices can be provided, and the electrode production equipment also includes multiple sets of rollers 20, each set of rollers 20 having two rollers. The two rollers 20 are spaced apart, and there is a roller gap between the two rollers 20. Each set of rollers 20 is respectively provided with a feeding device, thereby enabling the simultaneous production of multiple films.

[0075] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0076] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
