Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for conductive slurry. Background Technology

[0002] Conductive paste is a highly dispersed multiphase suspension system composed of conductive fillers, binders, solvents and additives. This material is mainly used in the fields of electronic component packaging, electrode fabrication, circuit printing and interconnection.

[0003] However, in actual use, the following shortcomings still exist. For example, existing feeding devices for conductive slurry cannot fully mix the conductive slurry before feeding. If the active materials, conductive agents, and binders in the conductive slurry are not fully mixed, it will lead to uneven particle distribution. This unevenness will affect the electrochemical performance of the battery because uneven distribution of active materials may lead to uneven distribution of current density inside the battery, thereby affecting the battery's capacity and cycle stability. Insufficiently mixed slurry is prone to sedimentation and stratification, that is, larger particles or heavier components will sink to the bottom, while lighter components will float on the top.

[0004] Therefore, this utility model proposes a feeding device for conductive paste to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for conductive slurry.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for conductive paste, comprising a feeding storage tank, wherein a feeding inlet is provided at the top of the feeding storage tank, a feeding port is provided at the bottom of the feeding storage tank, a stirring assembly is provided on the feeding storage tank, and a scraping assembly is provided on the stirring assembly;

[0007] The stirring assembly includes a first drive shaft and a first gear. A belt is mounted on the first drive shaft, and a second drive shaft is mounted on the belt. A first support block is fixedly connected to the second drive shaft. A second gear is rotatably connected to the first support block, and the second gear meshes with the first gear. A third gear is fixedly connected to the second gear. A limit block is fixedly connected to the first support block, and a toothed groove is formed in the limit block. A fourth gear meshes with the third gear, and a stirring blade is fixedly connected to the fourth gear.

[0008] The scraping assembly includes a support rod, a second support block is fixedly connected to the support rod, and a scraper is fixedly connected to the second support block.

[0009] In a preferred embodiment, a drive motor is installed on the feeding storage tank, the first drive shaft is fixedly connected to the output end of the drive motor, the first drive shaft is rotatably connected to the feeding storage tank, and the second drive shaft is rotatably connected to the feeding storage tank.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: Since a drive motor is installed on the feeding storage tank, and the first drive shaft is fixedly connected to the output end of the drive motor, starting the drive motor will cause the output end of the drive motor to drive the first drive shaft to rotate. Since the first drive shaft is rotatably connected to the feeding storage tank, the feeding storage tank can support and limit the rotation of the first drive shaft. Since the second drive shaft is rotatably connected to the feeding storage tank, the feeding storage tank can support and limit the rotation of the second drive shaft.

[0011] In a preferred embodiment, the first gear is fixedly connected to the feeding storage tank, the fourth gear meshes with the tooth groove, and the support rod is fixedly connected to the first support block.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: since the first gear is fixedly connected to the feeding storage tank, the feeding storage tank can support and limit the first gear; since the fourth gear meshes with the tooth groove, the third gear can drive the fourth gear to rotate within the limiting block when it rotates; since the support rod is fixedly connected to the first support block, the first support block can support and fix the support rod.

[0013] In a preferred embodiment, the feeding storage tank is provided with a vibration damping and buffering assembly, which includes a support base, a support plate slidably connected inside the support base, a cylinder fixedly connected inside the support base, a moving rod slidably connected to the cylinder, a telescopic rod fixedly connected inside the support base, and a first telescopic spring provided on the telescopic rod.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the stirring assembly stirs the conductive slurry in the feeding storage tank, the vibration generated by the feeding storage tank will be transmitted to the support plate through the fixed column. Through the cooperation of the cylinder, the moving rod, the telescopic rod and the first telescopic spring, the support plate can be buffered.

[0015] In a preferred embodiment, a hollow tube is fixedly connected to the support plate, a damping rod is fixedly connected inside the hollow tube, a second telescopic spring is provided on the damping rod, a fixed column is slidably connected inside the second telescopic spring, and one end of the fixed column is fixedly connected to the feeding storage tank.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the damping rod installed inside the hollow tube and the second telescopic spring work together to reduce vibration of the feeding storage tank.

[0017] In a preferred embodiment, one end of the second telescopic spring is fixedly connected to the hollow tube, and the other end of the second telescopic spring is fixedly connected to the fixed column.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, since one end of the second telescopic spring is fixedly connected to the hollow tube and the other end of the second telescopic spring is fixedly connected to the fixed column, the second telescopic spring can provide elastic force to the fixed column.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the operator adds conductive slurry into the feeding storage tank through the inlet. Then, the drive motor is started. The output of the drive motor drives the first drive shaft, belt, and second drive shaft to rotate. This causes the second drive shaft to rotate the first support block. Due to the rotation of the first support block and the fixation of the first gear, and the meshing of the first and second gears, the second and third gears rotate. This causes the fourth gear, meshing with the third gear, to rotate within the limiting block. Consequently, the stirring blades fixedly connected to the fourth gear rotate on the limiting block and rotate on their own, ensuring thorough mixing of the conductive slurry in the feeding storage tank. Through the cooperation of the support rod, the second support block, and the scraper, the scraper can remove the conductive slurry adhering to the inner wall of the feeding storage tank, thus solving the technical problem of insufficient and uneven mixing of the conductive slurry before feeding.

[0030] 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.

[0031] like Figures 1-3 As shown, this embodiment provides a technical solution: a feeding device for conductive paste, including a feeding storage tank 1, a feeding inlet 2 at the top of the feeding storage tank 1, a feeding port 3 at the bottom of the feeding storage tank 1, a stirring assembly 4 on the feeding storage tank 1, and a scraping assembly 5 on the stirring assembly 4.

[0032] like Figures 1-3 As shown, the stirring assembly 4 includes a first drive shaft 42 and a first gear 45. A belt 43 is provided on the first drive shaft 42, and a second drive shaft 44 is provided on the belt 43. A first support block 46 is fixedly connected to the second drive shaft 44. A second gear 47 is rotatably connected to the first support block 46. The second gear 47 meshes with the first gear 45. A third gear 48 is fixedly connected to the second gear 47. A limit block 49 is fixedly connected to the first support block 46. A tooth groove 410 is provided in the limit block 49. A fourth gear 411 meshes with the third gear 48. A stirring blade 412 is fixedly connected to the fourth gear 411.

[0033] like Figure 2As shown, the scraping assembly 5 includes a support rod 51, a second support block 52 fixedly connected to the support rod 51, and a scraper 53 fixedly connected to the second support block 52. The operator adds conductive slurry into the feeding storage tank 1 through the feed inlet 2, and then starts the drive motor 41. The output end of the drive motor 41 drives the first drive shaft 42, belt 43, and second drive shaft 44 to rotate. This transmission method allows the second drive shaft 44 to drive the first support block 46 to rotate. Due to the rotation of the first support block 46 and the fixation of the first gear 45, and the meshing of the first gear 45 with the second gear 47, the second gear 47 and... The third gear 48 will rotate, and further, the fourth gear 411 meshing with the third gear 48 will rotate within the limiting block 49, thereby causing the stirring blade 412 fixedly connected to the fourth gear 411 to rotate on the limiting block 49 and rotate itself. This rotation allows the stirring blade 412 to fully stir the conductive slurry in the feeding storage tank 1. At the same time, through the cooperation of the support rod 51, the second support block 52 and the scraper 53, the scraper 53 can scrape off the conductive slurry adhering to the inner wall of the feeding storage tank 1, thereby solving the technical problem that the conductive slurry was not fully stirred before feeding.

[0034] The above solution also has the problem that the stirring component 4, while stirring the conductive slurry in the feeding storage tank 1, cannot effectively reduce vibration in the feeding storage tank 1. Figures 1-3 As shown: A drive motor 41 is installed on the feeding storage tank 1. A first drive shaft 42 is fixedly connected to the output end of the drive motor 41 and is rotatably connected to the feeding storage tank 1. A second drive shaft 44 is rotatably connected to the feeding storage tank 1. Because the drive motor 41 is installed on the feeding storage tank 1 and the first drive shaft 42 is fixedly connected to the output end of the drive motor 41, starting the drive motor 41 will drive the first drive shaft 42 to rotate. Since the first drive shaft 42 is rotatably connected to the feeding storage tank 1, the feeding storage tank 1 can support and limit the rotation of the first drive shaft 42. Since the second drive shaft 44 is rotatably connected to the feeding storage tank 1... The feeding storage tank 1 can support and limit the rotation of the second drive shaft 44. The first gear 45 is fixedly connected to the feeding storage tank 1, the fourth gear 411 meshes with the tooth groove 410, and the support rod 51 is fixedly connected to the first support block 46. Since the first gear 45 is fixedly connected to the feeding storage tank 1, the feeding storage tank 1 can support and limit the first gear 45. Since the fourth gear 411 meshes with the tooth groove 410, the third gear 48 can drive the fourth gear 411 to rotate within the limiting block 49 when it rotates. Since the support rod 51 is fixedly connected to the first support block 46, the first support block 46 can support and fix the support rod 51.

[0035] like Figure 1 as well as Figure 4 As shown, a vibration damping and buffer assembly 6 is provided on the feeding storage tank 1. The vibration damping and buffer assembly 6 includes a support base 61, a support plate 62 slidably connected inside the support base 61, a cylinder 63 fixedly connected inside the support base 61, a moving rod 64 slidably connected to the cylinder 63, a telescopic rod 65 fixedly connected inside the support base 61, a first telescopic spring 66 provided on the telescopic rod 65, a hollow tube 67 fixedly connected to the support plate 62, a damping rod 68 fixedly connected inside the hollow tube 67, a second telescopic spring 69 provided on the damping rod 68, a fixed column 610 slidably connected inside the second telescopic spring 69, and one end of the fixed column 610 fixedly connected to... On the feeding storage tank 1, one end of the second telescopic spring 69 is fixedly connected to the hollow tube 67, and the other end of the second telescopic spring 69 is fixedly connected to the fixed column 610. When the stirring assembly 4 stirs the conductive slurry in the feeding storage tank 1, the vibration generated by the feeding storage tank 1 will be transmitted to the support plate 62 through the fixed column 610. Through the cooperation of the cylinder 63, the moving rod 64, the telescopic rod 65 and the first telescopic spring 66, the support plate 62 can be buffered. Through the cooperation of the damping rod 68 set in the hollow tube 67 and the second telescopic spring 69, the feeding storage tank 1 can be vibration reduced.

[0036] Working principle:

[0037] like Figures 1-4As shown, the operator adds conductive slurry into the feeding storage tank 1 through the feed inlet 2, and then starts the drive motor 41. The output of the drive motor 41 drives the first drive shaft 42, belt 43, and second drive shaft 44 to rotate. This transmission method allows the second drive shaft 44 to drive the first support block 46 to rotate. Due to the rotation of the first support block 46 and the fixation of the first gear 45, and the meshing of the first gear 45 with the second gear 47, the second gear 47 and the third gear 48 will rotate. Furthermore, the fourth gear 411, which meshes with the third gear 48, rotates within the limiting block 49, thereby causing the stirring blade 412 fixedly connected to the fourth gear 411 to rotate on the limiting block 49 and rotate itself. This rotation method allows the stirring blades 412 to fully stir the conductive slurry in the feeding storage tank 1. At the same time, through the cooperation of the support rod 51, the second support block 52 and the scraper 53, the scraper 53 can scrape off the conductive slurry adhering to the inner wall of the feeding storage tank 1. When the stirring assembly 4 stirs the conductive slurry in the feeding storage tank 1, the vibration generated by the feeding storage tank 1 will be transmitted to the support plate 62 through the fixed column 610. Through the cooperation of the cylinder 63, the moving rod 64, the telescopic rod 65 and the first telescopic spring 66, the support plate 62 can be buffered. Through the cooperation of the damping rod 68 and the second telescopic spring 69 set in the hollow tube 67, the feeding storage tank 1 can be vibration reduced.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
