Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production technology, and more specifically, it relates to a feeding device for mixing lithium battery binder raw materials. Background Technology
[0002] In the lithium battery production process, the ratio and mixing of binders is a crucial step. To ensure the performance and stability of lithium batteries, it is essential to accurately control the input of raw materials and ensure uniform mixing.
[0003] However, existing technologies often face some problems in this process, especially in terms of adjusting the amount of raw materials input. Because the input system of the equipment is relatively simple, it is not possible to flexibly adjust the amount of raw materials input according to actual production needs. This limits the precise control of the production process and may affect the quality stability of the final product. Traditional feeding equipment is prone to over- or under-feeding when handling different types and particle sizes of raw materials, which leads to inaccurate raw material ratios and affects the mixing effect and the performance of the binder.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a feeding device for mixing lithium battery binder raw materials, which has the following beneficial effects:
[0017] 1. This device uses a hydraulic cylinder-driven lifting mechanism, which can precisely control the feeding height according to production needs. The extension and retraction of the hydraulic cylinder causes the connecting frame to drive the feed pipe to move up and down. This design allows the feed pipe to be easily inserted into different mixing equipment, solving the problem of inconvenient adjustment of raw material input height in traditional equipment. Through this structure, the raw material can be stably transported into the mixing device, thereby ensuring the efficient operation of the production line and the stability of continuous feeding.
[0018] 2. The design of the regulating mechanism effectively solves the problem of inaccurate control of raw material flow rate and volume in traditional devices. By driving the linkage sleeve to rotate through the regulating sleeve, the sliding rod and push sleeve are moved, enabling the spiral plate to accurately regulate the flow rate of raw materials. The spiral plate regulates the flow rate of raw materials by squeezing or extending, allowing different types of raw materials to be precisely controlled according to requirements. This innovative design greatly improves the accuracy of raw material input, thereby effectively avoiding inaccurate raw material ratios and enabling flexible adjustment of the raw material input.
[0019] 3. By using a push spring to drive the positioning block and positioning groove, the adjusting sleeve can be stably positioned after adjustment. The introduction of the positioning function not only enhances the stability of the adjustment process, but also avoids possible errors and loosening during the adjustment process. This ensures accurate control of the equipment for a long time during use and effectively improves the reliability and durability of the device. Attached Figure Description

[0029] Please see Figures 1-5 A feeding device for mixing raw materials of lithium battery binder includes a support column 1 and a lifting mechanism. The lifting mechanism includes a connecting frame 2 and a hydraulic cylinder 3. The connecting frame 2 is rotatably connected to the top of the support column 1. The two ends of the hydraulic cylinder 3 are rotatably connected to the support column 1 and the connecting frame 2, respectively. A mounting frame 4 is rotatably connected to the top of the connecting frame 2. A feeding pipe 5 is fixedly mounted on the mounting frame 4. The feeding pipe 5 is provided with multiple sets, and each set has a feeding head 6 fixedly mounted at its bottom. Each set of feeding pipes 5 has an adjustment mechanism at its top. The adjustment mechanism includes a connecting sleeve 7 and an adjustment sleeve 8. The connecting sleeve 7 is fixedly mounted to the top of the feeding pipe 5. The adjustment sleeve 8 is rotatably mounted on the top of the connecting sleeve 7. A transmission sleeve 9 is threadedly connected to the inner wall of the connecting sleeve 7. A push sleeve 10 is fixedly mounted on the inner side of the transmission sleeve 9. A linkage sleeve 11 is fixedly mounted on the inner wall of the adjustment sleeve 8. A slide rod 12 is slidably mounted inside the linkage sleeve 11. A slider 13 is slidably mounted on the outer wall of the slide rod 12. A spiral plate 14 is connected between the slider 13 and the inner wall of the connecting sleeve 7. A bracket 15 is fixedly mounted at the bottom of the connecting sleeve 7. The bottom of the slide rod 12 is rotatably connected to the bracket 15.
[0030] The spiral plate 14 is made of spring steel to generate elastic deformation when subjected to force, thereby improving the sensitivity and accuracy of the adjustment response. The displacement of the spiral plate 14 is adjusted by the elastic deformation of the material to achieve dynamic control of the material flow.
[0031] The slide bar 12 is set as a polygon and is slidably connected to the linkage sleeve 11 and the slider 13 respectively. The structural design can prevent the slide bar 12 from rotating and slipping, ensuring that the action is synchronous and stable during linkage. The anti-rotation characteristics of the polygonal geometry are used to improve the reliability of transmission.
[0032] The outer wall of the slider 13 is rotatably connected to a connecting shaft 16. The connecting shaft 16 is fixedly connected to the bottom end of the spiral plate 14 and the push sleeve 10, so that when the slider 13 moves, it can drive the push sleeve 10 to move the spiral plate 14 synchronously. The coordinated action of the spiral adjustment mechanism is realized through the rotational transmission structure of the connecting shaft 16.
[0033] The outer wall of the adjusting sleeve 8 is provided with a positioning mechanism, which includes a positioning sleeve 17 and a positioning groove 18. The positioning sleeve 17 is fixed to the outer wall of the adjusting sleeve 8. The positioning groove 18 is provided in multiple sets distributed on the outer wall of the connecting sleeve 7. The inner wall of the positioning sleeve 17 is provided with sliding holes 19. Multiple sets of sliding holes 19 are provided, and each set of sliding holes 19 is connected to a push spring 20. The bottom end of each set of push springs 20 is connected to a positioning block 21. The multiple sets of positioning blocks 21 slide in the multiple sets of sliding holes 19, and the bottom end of each set abuts against the positioning groove 18. After adjustment, the positioning blocks 21 are automatically ejected to embed into the positioning groove 18 to fix the position of the adjusting sleeve 8. The spring force of the spring 20 drives the positioning blocks 21 to achieve rapid automatic positioning and prevent loosening.
[0034] The bottom ends of multiple positioning blocks 21 and the outer sides of positioning grooves 18 are all set in an arc shape, which can achieve smooth engagement and reduce friction and wear when inserted for positioning. The arc structure optimizes the contact surface shape, improves structural adaptability and service life.
[0035] The top of the adjusting sleeve 8 is rotatably connected to an external pipe 22, which is used to connect to an external pipeline to achieve adjustable height docking of the raw material conveying path. The rotatable connection allows for flexible adjustment of the interface direction and angle, improving compatibility.
[0036] A movable base 23 is fixedly installed at the bottom of the support column 1 to support the whole machine and to enable it to move. The mobility and on-site adaptability of the equipment are improved by setting a movable structure at the bottom.
[0037] In this embodiment, during use, the outer pipe 22 is connected to the external raw material conveying pipe. The rotating adjusting sleeve 8 drives the linkage sleeve 11 to rotate, the linkage sleeve 11 drives the slide rod 12 to rotate, and the slide rod 12 drives the push sleeve 10 and the transmission sleeve 9 to rotate. The transmission sleeve 9 is threadedly engaged with the inner wall of the connecting sleeve 7, so that the transmission sleeve 9 drives the push sleeve 10 to slide along the slide rod 12. The push sleeve 10 pushes the slider 13 to slide along the slide rod 12. The push sleeve 10 pushes the connecting shaft 16 to squeeze or extend the spiral plate 14, thereby allowing the spiral plate 14 to adjust the flow rate and flow of the raw material. After adjustment, multiple sets of push springs 20 push the positioning block 21 to abut in the positioning groove 18, thereby positioning the adjusting sleeve 8.
[0038] More specifically, the hydraulic cylinder 3 is activated so that its telescopic end pushes the connecting frame 2 to rotate along the support column 1. The connecting frame 2 drives the feed pipe 5 set on the mounting frame 4 to rise, and then the feed pipe 5 can be extended into the subsequent mixing device for feeding. The raw material enters the feed pipe 5 after passing through the adjustment mechanism, and finally is injected into the mixing device through the injection head 6.
[0039] In summary, during use or operation of the overall equipment: When in use, connect the outer pipe 22 to the external raw material conveying pipe, rotate the adjusting sleeve 8 to drive the linkage sleeve 11 to rotate, the linkage sleeve 11 to drive the slide rod 12 to rotate, the slide rod 12 to drive the push sleeve 10 and the transmission sleeve 9 to rotate, the transmission sleeve 9 and the inner wall of the connecting sleeve 7 are threaded together, so that the transmission sleeve 9 drives the push sleeve 10 to slide along the slide rod 12, and the push sleeve 10 pushes the slider 13 to slide along the slide rod 12, and the push sleeve 10 pushes the connecting shaft 16 to squeeze or extend the spiral plate 14, thereby allowing the spiral plate 14 to adjust the flow rate and flow of the raw material. After adjustment, multiple sets of push springs 20 push the positioning block 21 to abut in the positioning groove 18, thereby positioning the adjusting sleeve 8.
[0040] Start the hydraulic cylinder 3 so that its telescopic end pushes the connecting frame 2 to rotate along the support column 1. The connecting frame 2 drives the feed pipe 5 set on the mounting frame 4 to rise. Then the feed pipe 5 can be extended into the subsequent mixing device for feeding. The raw material enters the feed pipe 5 after passing through the adjustment mechanism, and finally is injected into the mixing device through the injection head 6.
