Technical Field

[0001] This utility model relates to the field of feeding technology for the production of carbon nanotube conductive slurry, specifically to a feeding device for the production of carbon nanotube conductive slurry. Background Technology

[0002] As is well known, carbon nanotube conductive pastes are widely used in electronics, energy, composite materials and other fields, highlighting their value as high-performance conductive fillers and their key role in the preparation of transparent conductive films, supercapacitors, lithium-ion batteries and other products.

[0003] A search revealed that Chinese utility model patent CN222714356U discloses a feeding device for processing carbon nanotube conductive slurry. The device includes a feeding machine body, a screw conveyor mechanism, and a top cover. One end of the feeding machine body has a feeding pipe. A hinge is provided between one side of the top cover and the feeding machine body. A feeding hopper is located at the top of the top cover. A fixing mechanism is provided between the other side of the top cover and the feeding machine body. The fixing mechanism includes a fixing groove and a fixing box. The fixing groove is located on the feeding machine body and has a docking block.

[0004] Although the above technical solutions solve the problems of effectively handling material changes and equipment cleaning, there may be dead corners of material residue under the screw shaft inside the feeder body, such as the connection between the end of the screw shaft and the feed pipe. These areas are difficult to reach during manual cleaning and may lead to cross-contamination between different batches of materials, especially when changing the formula. Summary of the Invention

[0005] Technical problems to be solved In order to overcome the problem of material residue in dead corners in existing feeding devices for the production of carbon nanotube conductive slurry, this utility model provides a feeding device for the production of carbon nanotube conductive slurry that does not leave material residue in dead corners.

[0006] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a feeding device for producing carbon nanotube conductive slurry, comprising: support; An adjustable base is mounted on the bottom of the bracket; A conveyor belt, which is fixedly mounted on the top of the support frame; Mounting frame, the mounting frame being fixedly mounted on the top of the conveyor belt; The feed inlet is fixedly disposed within the mounting frame; and A holding assembly is mounted on the conveyor belt and arranged in a matrix. Each holding assembly includes a holding frame, which is fixedly mounted on the conveyor belt and its arrangement is adapted to the conveyor belt. Sliding plates adapted to the shape of the conveyor belt are fixedly mounted on both sides of the conveyor belt and are slidably mounted with the holding frame. A first spring is fixedly mounted inside the holding frame, and a push plate is slidably mounted inside the holding frame. The push plate is fixedly mounted to the top of the first spring. A limiting component is mounted on the side of the holding frame and is adapted to the push plate.

[0007] Preferably, the limiting component includes sliding holes, which are formed on both sides of the holding frame. A limiting plate is slidably disposed in the sliding holes, and the limiting plate is in contact with the top of the push plate. A horizontal plate is fixedly disposed on the side of the limiting plate, and a second spring is fixedly disposed on the horizontal plate. The second spring is fixedly disposed with the holding frame.

[0008] Furthermore, the cross plate is made of magnetic iron.

[0009] Furthermore, mounting plates are fixedly installed on both sides of the conveyor belt, and magnets are fixedly installed on the mounting plates, the magnets being compatible with the cross plate.

[0010] In a further embodiment, at least two fixing frames are fixedly provided on the side of the conveyor belt, and threaded posts are provided on the fixing frames by threads, with one end of the threaded posts fitting against the side of the holding frame.

[0011] Based on the aforementioned scheme, the top of the fixing frame is provided with a threaded handle, and the bottom of the threaded handle is in contact with the threaded post.

[0012] Furthermore, based on the aforementioned solution, a mounting horizontal plate is fixedly installed inside the mounting frame, and a hydraulic rod is fixedly installed at the bottom of the mounting horizontal plate. A pressure plate is connected to the bottom of the hydraulic rod via a key, and the pressure plate is adapted to the holding frame.

[0013] Furthermore, based on the aforementioned solution, a scraper is fixedly installed at the bottom of the feeding port, and the scraper is in contact with the top of the holding frame.

[0014] Beneficial effects This feeding device for producing carbon nanotube conductive slurry has a push plate inside the holding frame that is linked to a first spring. When the holding frame moves to the feeding position with the conveyor belt, the limiting component triggers the push plate to move upward, using the spring force to push the bottom material upward, thoroughly removing the residue at the connection between the bottom of the holding frame and the spiral shaft. The first spring continuously provides upward thrust, making the push plate stick tightly to the inner wall of the holding frame. Even viscous materials, such as high-concentration carbon nanotube slurry, can be completely pushed to the feeding port, avoiding the dead corner formed by material accumulation at the angle between the end of the spiral shaft and the feeding pipe in traditional static structures.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-6 A feeding device for producing carbon nanotube conductive slurry includes a support 1, an adjustable base 2, a conveyor belt 3, a mounting frame 4, a feeding port 5, and a holding component 6.

[0019] The support frame 1 is made of high-strength metal material (such as stainless steel) as the overall support structure. The adjustable base 2 is installed at the bottom of the support frame 1. The height of the support frame 1 can be flexibly adjusted by screw or hydraulic mechanism to adapt to the feeding requirements of different heights. The conveyor belt 3 is fixedly set on the top of the support frame 1 and is driven by a motor to achieve continuous or intermittent operation for conveying the holding component 6. The mounting frame 4 is fixed on the top of the conveyor belt 3. The feeding port 5 is embedded in the mounting frame 4 and its position is aligned with the moving path of the holding component 6 to ensure accurate material feeding.

[0020] The holding components 6 are arranged in a matrix on the conveyor belt 3. Each holding component 6, including the holding frame 7, is made of corrosion-resistant plastic or metal and is fixed on the conveyor belt 3. The spacing between them is adapted to the transmission tooth pitch of the conveyor belt 3 to ensure stability during movement.

[0021] The sliding plate 8 has L-shaped sliding plates 8 that match the shape of the conveyor belt 3 fixed on both sides. The inner side of the sliding plate 8 has a guide groove that slides and cooperates with the protrusions on both sides of the holding frame 7 to limit the movement trajectory of the holding frame 7 and prevent deviation.

[0022] The first spring 9 and the push plate 10 are fixed to the bottom surface of the container 7. The first spring 9 (such as a compression spring) is connected to the top of the push plate 10. The push plate 10 is a rectangular plate with its edge sliding against the inner wall of the container 7. It can push the material upward under the elastic force of the first spring 9.

[0023] The limiting component 11 is installed on the side of the holding frame 7. The initial position of the push plate 10 can be adjusted to control the amount of material fed into the holding frame 7.

[0024] In the initial state, by adjusting the limiting component 11, the push plate 10 is moved down to the bottom of the holding frame 7. At this time, the first spring 9 is in a compressed state, and the carbon nanotube conductive slurry raw material is loaded into the holding frame 7, and the material accumulates above the push plate 10.

[0025] After the conveyor belt 3 starts, the holding component 6 moves with the conveyor belt 3 toward the mounting frame 4. When the holding frame 7 reaches directly below the feeding port 5, the conveyor belt 3 stops running. At this time, the limiting component 11 triggers the unlocking mechanism in the mounting frame 4 to release the limit on the push plate 10. The first spring 9 releases its elastic force, and the push plate 10 moves upward to push the material out of the feeding port 5, thus completing the feeding.

[0026] After the reset and cyclic feeding are completed, the conveyor belt 3 starts again, and the empty holding component 6 returns to the loading position with the belt. The push plate 10 is readjusted to the bottom by the limit component 11, and the material is loaded again to enter the next cycle.

[0027] The adjustable base 2 includes a threaded sleeve at the bottom of the bracket 1, an adjusting screw screwed into the sleeve, and an anti-slip base fixed at the bottom of the screw. The vertical height of the bracket 1 can be changed by rotating the screw, which is suitable for fine-tuning scenarios.

[0028] Electromagnetic locks can be used to replace limit components 11, and locking and releasing can be controlled by an electronic control system to achieve automated feeding and improve production efficiency.

[0029] The container 7 has been improved by providing an anti-stick coating (such as polytetrafluoroethylene) on its inner wall to reduce slurry adhesion and facilitate cleaning.

[0030] The conveyor belt 3 can be driven by a variable frequency motor, which can flexibly adjust the transmission speed according to the production rhythm and adapt to different feeding frequency requirements.

[0031] This device achieves quantitative and continuous feeding of carbon nanotube conductive slurry through the cooperation of matrix-type holding component 6 and conveyor belt 3, avoiding errors and contamination problems caused by manual feeding. The design of adjustable base 2 and limiting component 11 improves the applicability and accuracy of the device. The guiding structure of sliding plate 8 ensures the stability of the movement of holding frame 7. The overall structure is compact, easy to maintain, and suitable for industrial production scenarios.

[0032] First, refer to Figure 6 In this embodiment, the holding frame 7 has horizontally sliding holes 12 on both sides. A limiting plate 13 (with a thickness adapted to the sliding hole 12) is slidably disposed in the sliding hole 12. The bottom of the limiting plate 13 is attached to the top of the push plate 10. In the initial state, the horizontal movement of the limiting plate 13 can restrict the push plate 10 from moving upward (i.e., lock the material). A horizontal plate 14 (made of magnetic iron) is fixedly connected to the side of the limiting plate 13. A second spring 15 (tension spring) is fixedly disposed between the horizontal plate 14 and the outer side of the holding frame 7. Under normal conditions, the second spring 15 applies a force to the horizontal plate 14 in the direction of the holding frame 7. The tension keeps the limiting plate 13 in contact with the push plate 10 (locked position). Mounting plates 16 are fixedly installed on both sides of the conveyor belt 3. Magnets 17 are fixed on the mounting plates 16 at positions corresponding to the moving path of the holding frame 7 (such as directly below the feed port 5). When the holding frame 7 moves with the conveyor belt 3 to the opposite side of the magnet 17, the magnet 17 attracts the horizontal plate 14 (magnetic iron), overcomes the tension of the second spring 15, and drives the horizontal plate 14 to slide outward, thereby causing the limiting plate 13 to disengage from the push plate 10 (unlocked position). At this time, the first spring 9 pushes the push plate 10 to move upward to complete the feeding.

[0033] Then, refer to Figure 3In this embodiment, to ensure the stability of the holding frame 7 during the conveying process, at least two fixing frames 18 (distributed along the length of the conveyor belt 3) are provided on the side of the conveyor belt 3. Threaded posts 19 are vertically threaded through the fixing frames 18. The lower end of the threaded posts 19 fits against the side of the holding frame 7 (such as a lug). The extension length can be adjusted by rotating the threaded posts 19 to adapt to holding frames 7 of different sizes. Threaded handles 20 (perpendicular to the threaded posts 19) are threaded through the top of the fixing frames 18. The bottom of the threaded handles 20 fits against the side of the threaded posts 19. After tightening, the position of the threaded posts 19 can be locked to prevent them from loosening due to vibration. This design realizes the quick clamping and fine-tuning of the position of the holding frame 7, and is compatible with the feeding requirements of different specifications.

[0034] Secondly, see Figure 2 In this embodiment, a hydraulic drive assembly for auxiliary feeding is provided inside the mounting frame 4. A horizontal mounting plate 21 is fixed to the inner side wall of the mounting frame 4, and a hydraulic rod 22 (such as a miniature hydraulic cylinder) is vertically fixed to the bottom of the horizontal plate 14. The piston rod of the hydraulic rod 22 extends downward and is connected to the pressure plate 23 via a key (to prevent circumferential rotation). The size of the pressure plate 23 is adapted to the top opening of the holding frame 7 (smaller than the opening). When the holding frame 7 moves to directly below the feeding port 5 and the limiting assembly 11 is unlocked, the hydraulic rod 22 is activated, pushing the pressure plate 23 down, forming a bidirectional force with the pushing plate 10 (pushed upward by the first spring 9), ensuring that the carbon nanotube slurry (especially high-viscosity slurry) is completely discharged from the feeding port 5, avoiding residue.

[0035] Finally, see Figure 2 In this embodiment, a scraper 24 (such as an elastic rubber plate or a stainless steel sheet) is fixedly installed at the bottom of the feeding port 5 (on the side near the conveyor belt 3). The lower edge of the scraper 24 is in contact with the top surface of the holding frame 7. When the holding frame 7 finishes feeding and leaves the feeding port 5 with the conveyor belt 3, the scraper 24 scrapes off the slurry residue adhering to its surface by friction with the top of the holding frame 7, so as to avoid the accumulation of slurry causing the subsequent holding frame 7 and sliding plate 8 to get stuck, while maintaining the cleanliness of the device.

[0036] Working principle: When using this feeding device for producing carbon nanotube conductive slurry, firstly, by adjusting the threaded post 19 and threaded handle 20 on the fixing frame 18, the holding frame 7 is fixed at a suitable position on the conveyor belt 3. Then, the push plate 10 is pressed down to compress the first spring 9, and the carbon nanotube conductive slurry raw material is loaded into the holding frame 7. At this time, the limiting plate 13 of the limiting component 11 is attached to the top of the push plate 10 under the action of the second spring 15, which restricts the push plate 10 from moving upward, thus completing the material loading.

[0037] Start the conveyor belt 3, and the holding component 6 moves with the conveyor belt 3 toward the mounting frame 4. The sliding plates 8 on both sides of the conveyor belt 3 ensure that the holding frame 7 moves along a fixed track to avoid deviation. When the holding frame 7 moves to directly below the feeding port 5, the conveyor belt 3 stops running and the holding frame 7 is precisely positioned.

[0038] When the holding frame 7 moves to the position of the magnet 17, the magnet 17 attracts the horizontal plate 14 (made of magnetic iron), overcoming the tension of the second spring 15, causing the limiting plate 13 to slide outward, disengaging from the push plate 10, releasing the limitation on the push plate 10, the first spring 9 releases its elastic force, and the push plate 10 moves upward under the action of the spring force, pushing the material out of the conveying port 5. At the same time, the hydraulic rod 22 in the mounting frame 4 is activated, and the pressure plate 23 presses down, forming a bidirectional force with the push plate 10 to ensure that the high viscosity slurry is completely discharged.

[0039] When the container 7 leaves the feed inlet 5 along with the conveyor belt 3, the scraper 24 at the bottom of the feed inlet 5 comes into contact with the top of the container 7 to scrape off the slurry residue adhering to the surface, keep the device clean, and avoid jamming.
