[0034] like Figure 1-8 As shown, this embodiment provides a powder distributing device and a powder processing device. The powder processing device includes a powder distributing device 10 and a powder processing device 20 . The powder distributing device 10 is used to supply powder to the powder processing device 20 .

[0035] The powder material distributing device 10 includes a storage mechanism 1, a distributing mechanism 2 and a conveying mechanism 3. The storage mechanism 1 includes a storage hopper 11 and a vibration driving member 12. The vibration driving member 12 is used to vibrate the storage hopper 11. The bottom of the storage hopper 11 is provided with a discharge port 111; the distributing mechanism 2 includes a transfer bin 21, a distributing roller 22 and a distributing driving unit 23. The transfer bin 21 includes a feed port 211 and a distributing port 212. The feed port 211 is correspondingly arranged and connected to the discharge port 111. The material inlet 212 is located at the bottom of the transfer silo 21; the material distribution roller 22 is rotatably disposed within the transfer silo 21, and the material distribution drive unit 23 is used to drive the material distribution roller 22 to rotate. The outer peripheral surface of the material distribution roller 22 is provided with a plurality of material troughs 221 evenly distributed along the circumference of the material distribution roller 22; the conveying mechanism 3 includes a conveyor belt 31 and a conveyor drive unit. The conveyor belt 31 is located below the material distribution inlet 212, and the conveyor drive unit is used to drive the conveyor belt 31 to rotate to convey the powder to the powder processing device 20. In this embodiment, the powder processing device 20 includes a film-forming roller 201 for rolling the powder into a film, and the conveyor belt 31 is used to convey the powder to the film-forming roller 201. Exemplarily, two film-forming rollers 201 are provided, and the two film-forming rollers 201 rotate relative to each other to roll and form a film on the powder passing between the two film-forming rollers 201.

[0036] The powder distributing device 10 of this embodiment vibrates the storage hopper 11 through the vibration driving member 12, which effectively solves the problem of powder agglomeration and enables the powder to fall into the material trough 221 on the distributing roller 22 through the discharge port 342 and the feed port 211. The distributing roller 22 is then driven to rotate by the distributing driving unit 23 to evenly spread the powder on the conveyor belt 31. Finally, the conveyor driving unit drives the conveyor belt 31 to rotate and delivers the powder to the powder processing device 20, thereby achieving uniform discharging of the powder. Compared with the manual discharging method, the discharging speed is greatly improved while ensuring the uniformity of the discharging.

[0037] It should be noted that the shapes and sizes of the plurality of material troughs 221 are equal, so that the volumes of the plurality of material troughs 221 are equal. By rotating the material distribution roller 22 at a constant speed, uniform material distribution can be achieved.

[0038] Optionally, the accumulator mechanism 1 further includes a first material width adjustment assembly 13, which includes two first material stoppers 131 disposed relative to the accumulator 11 along a first direction. Both first material stoppers 131 are disposed within the accumulator 11, and at least one of the first material stoppers 131 is adjustable in position along the first direction. By adjusting the installation position of the first material stoppers 131 in the first direction, the width of the discharge port 111 along the first direction is adjusted, thereby achieving the purpose of adjusting the discharge width. The axial direction of the material distribution roller 22 is parallel to the first direction.

[0039] It should be noted that a storage cavity 1311 is formed between the two first blocking members 131, and the discharge port 111 is located at the bottom of the storage cavity 1311. By adjusting the installation position of the first blocking member 131 in the first direction, the width of the storage cavity 1311 along the first direction can be adjusted, and then the width of the discharge port 111 along the first direction can be adjusted.

[0040] Optionally, the cloth mechanism 2 further includes a second material width adjustment assembly 24, which includes a second material stop 241 arranged in a one-to-one correspondence with the two first material stops 131. The two second material stops 241 are both arranged on the cloth roller 22. The second material stop 241 includes a plurality of material stops 2411 respectively located in a plurality of material troughs 221. The second material stops 241 corresponding to the position-adjustable first material stops 131 are adjustably arranged along the first direction. It should be noted that a transfer cavity 24111 is formed between the two material stops 2411 located in the same material trough 221. By adjusting the installation position of the second material stop 241 in the first direction, the width of the transfer cavity 24111 along the first direction can be adjusted, thereby achieving the purpose of adjusting the cloth width. At the same time, the width of the transfer chamber 24111 along the first direction can be made equal to the width of the discharge port 111 along the first direction, and the transfer chamber 24111 is aligned with the discharge port 111, so that when the powder flows on the storage mechanism 1 and the distribution mechanism 2, the position of the powder in the first direction remains unchanged, which is beneficial to improving the uniformity of powder feeding.

[0041] Optionally, the conveying mechanism 3 further includes a conveying material width adjustment component 32, which includes a conveying material width adjustment component 32 that is arranged in a one-to-one correspondence with the two second material stops 241. The two conveying material stops 321 are both arranged on the conveyor belt 31, and the conveying material stops 321 corresponding to the position-adjustable second material stops 241 are adjustably arranged along the first direction. Such an arrangement allows the powder falling on the conveyor belt 31 to be located between the two conveying material stops 321, ensuring that the powder is evenly spread on the conveyor belt 31, which is conducive to improving the uniformity of material discharging and thereby improving the film forming quality. According to the installation position of the second material stops 241 in the first direction, the installation position of the conveying material stops 321 in the first direction is adjusted, so that the position of the powder in the first direction remains unchanged when the powder flows on the distributing mechanism 2 and the conveying mechanism 3, which is conducive to improving the uniformity of powder discharging.

[0042] It should be noted that the conveying stopper 321 is arranged on the conveyor belt 31. Specifically, the conveying stopper 321 is fixed above the conveyor belt 31, and a small gap is provided between the conveying stopper 321 and the conveyor belt 31. Under the premise of not affecting the rotation of the conveyor belt 31, the conveying stopper 321 plays a blocking role on the powder on the conveyor belt 31.

[0043] Optionally, the powder distributing device 10 further includes a downstream material width adjustment component 41, which includes a downstream material width adjustment component 411 that is arranged in a one-to-one correspondence with the two conveying material stops 321. The two downstream material stops 411 are both arranged on the powder processing device 20, and the downstream material stops 411 corresponding to the position-adjustable conveying material stops 321 are adjustably arranged along the first direction. Such an arrangement allows the powder delivered to the powder processing device 20 to be located between the two downstream material stops 411, which is beneficial to improving the uniformity of material discharging and thereby improving the film forming quality. According to the installation position of the second material stop 241 in the first direction, the installation position of the downstream material stop 411 in the first direction is adjusted, so that the position of the powder in the first direction remains unchanged during the process of the powder flowing from the distributing mechanism 2 and the conveying mechanism 3 to the film forming roller 201, which is beneficial to improving the uniformity of powder discharging.

[0044] It should be noted that, in this embodiment, the downstream material blocking member 411 is arranged on the film-forming roller 201. Specifically, the downstream material blocking member 411 is fixed above the film-forming roller 201, and a small gap is provided between the downstream material blocking member 411 and the film-forming roller 201. Under the premise of not affecting the rotation of the film-forming roller 201, the downstream material blocking member 411 plays a blocking role on the powder on the film-forming roller 201.

[0045] Optionally, the two first material stops 131 are both adjustable along the first direction on the storage hopper 11. Furthermore, the two second material stops 241 are both adjustable along the first direction on the distribution roller 22. Furthermore, the two conveying material stops 321 are both adjustable along the first direction on the conveyor belt 31. Furthermore, the two downstream material stops 411 are both adjustable along the first direction on the powder processing device 20.

[0046] This arrangement ensures that the powder's position in the first direction remains unchanged as it flows from the storage mechanism 1, distribution mechanism 2, and conveying mechanism 3 to the film-forming roller 201, thereby improving uniformity of material delivery. It also facilitates positioning the powder in the middle of the film-forming roller 201 along the first direction, which helps to improve the uniformity of the force applied to the powder and, in turn, enhance film quality.

[0047] Optionally, the first material width adjustment component 13 further includes a first driving unit 132, which is used to drive the position-adjustable first material stopper 131 to move along the first direction, thereby facilitating the control of the first material stopper 131 to move along the first direction, and is easy to operate.

[0048] For example, the two first material stops 131 are slidably disposed within the hopper 11 along a first direction. The first drive unit 132 includes a lead screw 1321 and a handwheel 1322. The two first material stops 131 are respectively threadedly connected to the ends of the lead screw 1321, with the threads at the ends of the lead screw 1321 rotating in opposite directions. The handwheel 1322 is fixed to one end of the lead screw 1321. By manually rotating the lead screw 1321, the two first material stops 131 can be driven toward or away from each other. Of course, a rotational drive member such as a motor can also be provided to drive the lead screw 1321 to rotate.

[0049] It should be noted that a small gap is provided between the first material stopper 131 and the inner wall of the storage hopper 11 , so that the first material stopper 131 blocks the powder without affecting the movement of the first material stopper 131 along the first direction.

[0050] Optionally, the second material stopper 241 is locked or unlocked with the material roller 22 via the material locking member 242 , thereby facilitating adjustment of the installation position of the second material stopper 241 along the first direction without affecting the rotation of the material roller 22 .

[0051] Exemplarily, the fabric locking member 242 is a screw, and the outer surface of the fabric roller 22 is provided with a plurality of groups of threaded holes arranged in sequence along the first direction, and each group includes a plurality of threaded holes arranged in sequence along the circumference of the fabric roller 22. By passing one end of the screw through the second material stop 241 and threadedly connected to the threaded holes at different positions on the fabric roller 22, the installation position of the second material stop 241 in the first direction can be adjusted, and the convenience of disassembly and assembly of the second material stop 241 can be improved.

[0052] Optionally, the material distribution roller 22 includes a roller body 222 and a plurality of third material stops 223. The roller body 222 is rotatably disposed within the transfer bin 21. The plurality of third material stops 223 are evenly distributed along the circumference of the roller body 222, with a material trough 221 formed between two adjacent third material stops 223. This arrangement facilitates the manufacture of the material distribution roller 22.

[0053] Furthermore, the plurality of third material stoppers 223 are detachably connected to the roller body 222 via locking members such as screws. By adjusting the distance between two adjacent third material stoppers 223 , the volume of the material trough 221 can be adjusted, which makes it more versatile.

[0054] Specifically, the plurality of stoppers 2411 are independently provided stoppers, which are sandwiched between two adjacent third stoppers 223. Of course, the second stopper 241 can also be a stopper ring of an integrated structure, with an avoidance groove provided between two adjacent stoppers 2411, and a stopper 2411 sandwiched between two adjacent third stoppers 223, with the third stopper 223 inserted into the avoidance groove.

[0055] Optionally, the conveying mechanism 3 includes a conveying mounting member 33, and the conveying drive unit includes a conveying drive member and two conveying rollers. The two conveying rollers are rotatably mounted on the conveying mounting member 33, and the conveyor belt 31 is wound around the outside of the two conveying rollers. The conveying drive member drives one of the conveying rollers to rotate, thereby driving the conveyor belt 31 to rotate. Exemplarily, the conveying drive member is a rotating drive member such as a motor.

[0056] Optionally, the conveying material stopping member 321 is locked or unlocked with the conveying mounting member 33 through a conveying locking member, thereby facilitating adjustment of the installation position of the conveying material stopping member 321 along the first direction.

[0057] Furthermore, a plurality of conveying locking members are provided to improve the installation stability of the conveying mounting member 33. For example, both ends of the conveying material blocking member 321 are provided with conveying locking members.

[0058] Specifically, the conveying stopper 321 includes a mounting rod 3211, which is slidably arranged on the conveying mounting member 33 along a first direction, and the conveying locking member includes a damper, which is fixed to the conveying mounting member 33 and sleeved on the outer side of the mounting rod 321. During the operation of the conveyor belt 31, the force of the powder acting on the conveying stopper 321 is small, and the damping force provided by the damper can lock the conveying stopper 321 with the conveying mounting member 33; pushing the conveying stopper 321 and overcoming the damping force of the damper can achieve unlocking to adjust the position of the conveying stopper 321.

[0059] Optionally, the powder processing device 20 includes a downstream mounting member 42. In this embodiment, the film-forming roller 201 is rotatably mounted on the downstream mounting member 42, and the downstream material stopper 411 is locked or unlocked with the downstream mounting member 42 via a downstream locking member. Specifically, two film-forming rollers 201 are provided, each rotatably mounted on the downstream mounting member 42. The two film-forming rollers 201 are disposed opposite each other and rotate in opposite directions to crush the powder passing between the two film-forming rollers 201.

[0060] Furthermore, a plurality of downstream locking members are provided to improve the installation stability of the downstream material stopper 411. Exemplarily, both ends of the downstream material stopper 411 are provided with downstream locking members.

[0061] Specifically, the downstream mounting member 42 includes a processing hopper 421, and two downstream material blocking members 411 are both arranged in the processing hopper 421. The processing hopper 421 is provided with a slide rod 4211. The downstream material blocking member 411 can be slidably mounted on the slide rod 4211 along a first direction. The downstream locking member includes a clamp 43, and the clamp 43 is mounted on the outer side of the slide rod 4211 and fixedly connected to the downstream material blocking member 411. By locking the clamp 43, the clamp 43 can be made to clamp the slide rod 4211 to lock the downstream material blocking member 411 and the slide rod 4211; by loosening the clamp 43, the position of the downstream material blocking member 411 along the first direction can be adjusted.

[0062] Optionally, the fabric drive unit 23 includes a fabric drive member 231, which directly drives the fabric roller 22 to rotate. Of course, the fabric drive unit 23 may also include a reducer, with the input end of the reducer connected to the fabric drive member 231 and the output end connected to the fabric roller 22, to improve the speed control accuracy of the fabric roller 22, thereby further improving the uniformity of the fabric. Exemplarily, the fabric drive member 231 is a rotary drive member such as a motor.

[0063] Optionally, two vibration drive members 12 are provided, and the two vibration drive members 12 are respectively provided on both sides of the storage hopper 11, which has the effect of preventing the powder from agglomerating. Exemplarily, the vibration drive member 12 is a vibration motor.

[0064] Optionally, the storage mechanism 1 further includes a storage level detection element 14 and a material shortage alarm. The storage level detection element 14 is used to detect the material level of the powder material in the storage hopper 11, and the material shortage alarm is communicatively connected to the storage level detection element 14. The storage level detection element 14 is used to detect whether the material level of the powder material in the storage hopper 11 is lower than the storage lower limit. When the storage level detection element 14 detects that the material level of the powder material in the storage hopper 11 is lower than the storage lower limit, the material shortage alarm sounds an alarm to remind the staff to add material in time, thereby having a high degree of automation.

[0065] Optionally, the powder distribution device 10 also includes a downstream material level detection component 44, which is used to detect the material level of the powder accumulated on the powder processing device 20. The downstream material level detection component 44 is communicatively connected to the distribution drive unit 23 so that the distribution drive unit 23 can control the rotation speed of the distribution roller 22 according to the detection result of the downstream material level detection component 44.

[0066] Specifically, there are two downstream material level detection members 44, which are respectively designated as the downstream material level upper limit detection member and the downstream material level lower limit detection member. When the downstream material level upper limit detection member detects that the material level of the powder material accumulated on the powder material processing device 20 is higher than the upper limit of the material pile, the speed at which the material distribution drive unit 23 drives the material distribution roller 22 to rotate is reduced, thereby reducing the material discharge speed and reducing the accumulation of powder material. When the downstream material level lower limit detection member detects that the material level of the powder material accumulated on the powder material processing device 20 is lower than the lower limit of the material pile, the speed at which the material distribution drive unit 23 drives the material distribution roller 22 to rotate is increased, thereby increasing the material discharge speed, thereby achieving dynamic closed-loop adjustment of the material discharge speed, thereby effectively solving the problem of inconsistent film surface density caused by excessive material level height difference, and at the same time being beneficial to achieving mass production of film formation.

[0067] Specifically, the powder material distribution device 10 also includes a control system. The vibration drive component 12, the material distribution drive unit 23, the conveying drive unit, the storage material level detection component 14, the material shortage alarm and the downstream material level detection component 44 are all communicatively connected to the control system. The control system is used to control the action of the vibration drive component 12, the material distribution drive unit 23 and the conveying drive unit. The storage material level detection component 14 and the downstream material level detection component 44 can send their respective detection results to the control system. The control system can also control the action of the material distribution drive unit 23 and the conveying drive unit according to the detection results of the storage material level detection component 14 and the downstream material level detection component 44.

[0068] Optionally, the feeding mechanism 2 further includes a bin door 25, which is slidably disposed at the feeding opening 212 along the first direction. By adjusting the opening of the bin door 25 so that the width of the feeding opening 212 along the first direction is consistent with the width of the transfer cavity 24111 along the first direction, it is prevented that the powder remaining in the area other than the transfer cavity 24111 in the trough 221 falls onto the conveyor belt 31.

[0069] Specifically, two doors 25 are provided, and the two doors 25 are respectively provided on both sides of the material distributing opening 212 along the first direction.

[0070] Optionally, the transfer silo 21 is provided with a scale 26 , which is used to measure the opening of the silo door 25 , thereby facilitating the control and viewing of the opening of the silo door 25 .

[0071] Optionally, the conveying mechanism 3 further includes an outer cover 34, which is sleeved on the outside of the conveyor belt 31. One end of the outer cover 34 is provided with an opening 341 through which the conveyor belt 31 extends. The outer cover 34 is also provided with a discharge port 342 corresponding to the feed port 212. Providing the outer cover 34 on the outside of the conveyor belt 31 can prevent powder from scattering into the air and escaping.

[0072] Optionally, the conveying mechanism 3 further includes a collecting tray 35 , which is disposed below the conveyor belt 31 , so that the powder remaining on the conveyor belt 31 can fall into the collecting tray 35 to prevent the powder from escaping.

[0073] Optionally, the conveying mechanism 3 further includes a cleaning member 36 , which abuts against the surface of the conveyor belt 31 and is located behind the material dispensing opening 212 along the conveying direction of the conveyor belt 31 . Therefore, before the powder material falling through the material dispensing opening 212 lands on the conveyor belt 31 , the cleaning member 36 removes any remaining powder material on the conveyor belt 31 , thereby facilitating precise control of the amount of powder material discharged. Exemplarily, the cleaning member 36 is a brush.

[0074] Specifically, the cleaning member 36 and the powder processing device 20 are respectively provided at both ends of the conveyor belt 31. Optionally, one end of the collecting tray 35 extends below the cleaning member 36, so that the collecting tray 35 can collect the powder removed by the cleaning member 36.

[0075] For example, the working principle of the powder processing equipment of this embodiment is:

[0076] First, adjust the first material width adjustment component 13, the second material width adjustment component 24, the conveying material width adjustment component 32 and the downstream material width adjustment component 41 according to the film forming width, so that the spacing between the two first material stops 131, the spacing between the two second material stops 241, the spacing between the two conveying material stops 321 and the spacing between the two downstream material stops 411 are equal, and the two second material stops 241 are aligned one by one with the two first material stops 131, the two conveying material stops 321 are aligned one by one with the two second material stops 241, the two downstream material stops 411 are aligned one by one with the two conveying material stops 321, and the two downstream material stops 411 are symmetrically arranged about the center line of the film forming roller 201, and the center line is perpendicular to the axis of the film forming roller 201, so that the powder falling on the film forming roller 201 is located in the middle of the film forming roller 201 along the first direction, so as to improve the uniformity of the force on the powder, thereby improving the film forming quality.

[0077] The powder is then manually loaded into the storage hopper 11, where the vibration motor breaks up the agglomerated powder. The powder passes through the discharge port 111 and the feed port 211 and falls into the trough 221 of the distribution roller 22. The distribution drive unit 23 drives the distribution roller 22 to rotate at a constant speed, evenly spreading the powder on the conveyor belt 31. Finally, the conveyor drive unit drives the conveyor belt 31 to rotate, conveying the powder to the film-forming roller 201, where the film-forming roller 201 compresses the powder into a film.

[0078] To sum up, the discharge widths of the first material width adjustment component 13, the second material width adjustment component 24, the conveying material width adjustment component 32 and the downstream material width adjustment component 41 can be adjusted to meet the production requirements of different film widths; the cloth mechanism 2 and the conveying mechanism 3 can both adjust the speed to meet the production requirements of different film production capacities; the downstream material level detection component 44 can detect the material level of the powder accumulated on the powder processing device 20, so that the cloth drive unit 23 can control the rotation speed of the cloth roller 22 according to the detection result of the downstream material level detection component 44, thereby realizing dynamic closed-loop adjustment of the discharge speed, effectively solving the problem of inconsistent film surface density caused by excessive material level height difference, and at the same time beneficial to the realization of mass production operation of film formation.
