Description

Technical Field

[0001] This utility model relates to the field of quantitative feeding technology for packaging, and in particular to a quantitative feeding structure for a ternary precursor packaging device. Background Technology

[0002] Ternary precursors are key raw materials used to prepare ternary cathode materials for lithium-ion batteries. They are mainly nickel-cobalt-manganese hydroxides, which are synthesized from nickel salts, cobalt salts, and manganese salts. By adjusting the ratio of nickel, cobalt, and manganese, the performance of the cathode material can be optimized.

[0003] However, this powder has poor flowability, is prone to bridging, and is sensitive to moisture. Traditional packaging machines use screw or valve feeding, which often results in material blockage, adhesion, and shoving. At the same time, existing ternary precursor quantitative feeding devices are not convenient for adjusting the quantitative amount of material according to packaging specifications after quantitative adjustment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quantitative feeding structure for a ternary precursor packaging device.

[0005] This utility model is achieved using the following technical solution: a quantitative feeding structure for a ternary precursor packaging device, comprising a base, an mounting plate fixedly connected to the top of the base, a quantitative cylinder fixedly installed inside the mounting plate, a feeding hopper fixedly connected to the top of the quantitative cylinder, an mounting platform fixedly connected to the top of the base, a hydraulic telescopic rod installed inside the mounting platform, a limit cylinder fixedly connected to the output end of the hydraulic telescopic rod, a connecting rod fixedly connected to the left end of the limit cylinder, a connecting plate fixedly connected to the left end of the connecting rod, a quantitative disc fixedly connected to the connecting disc via an adjusting component, and a feeding hopper fixedly connected to the bottom of the quantitative cylinder.

[0006] The above technical solution involves setting up a hydraulic telescopic rod, a limiting cylinder, a metering disc, and an inclined metering cylinder. During operation, the hydraulic telescopic rod pushes the limiting cylinder to slide along the inner wall of the metering cylinder, forming a metering cavity with a fixed volume between the limiting cylinder and the metering disc. As the process continues, the entire cavity is moved to the top of the discharge hopper to complete the discharge.

[0007] As a further improvement to the above solution, the distance between the metering cylinder and the bottom of the base gradually increases from left to right, and the surface of the limiting cylinder contacts the inner wall of the limiting cylinder.

[0008] By using the above technical solution, the angle between the axis of the metering cylinder and the bottom surface of the base gradually increases from left to right. During operation, the material automatically slides to the left and fills the metering chamber under its own weight, without the need for additional vibration or air blowing, thus simplifying the drive.

[0009] As a further improvement to the above solution, the number of connecting rods is set to two, and the two connecting rods are distributed in a circumferential array on the left end surface of the limiting cylinder.

[0010] By using the above technical solution, the two connecting rods are arranged in a circumferential array on the left end face of the limiting cylinder. During operation, the thrust is symmetrically transmitted to the connecting plate and the metering plate, avoiding jamming and uneven wear caused by unilateral force, thus achieving the effect of improving sliding synchronization and extending the sealing life.

[0011] As a further improvement to the above solution, the connecting plate and the metering plate are concentric, and the surfaces of both the connecting plate and the metering plate are slidably connected to the inner wall of the metering cylinder.

[0012] By using the above technical solution, the connecting plate and the metering plate are kept concentric and their outer circles slide against the inner wall of the metering cylinder. During operation, both plates simultaneously play a sealing and guiding role, cutting off the material backflow path, thus achieving the effect of clear metering cavity boundaries and no material leakage.

[0013] As a further improvement to the above solution, a limiting groove is formed on the surface of the connecting disc, and a limiting rod is fixedly connected to the inner wall of the metering cylinder.

[0014] As a further improvement to the above solution, two limiting grooves are provided, and the two limiting grooves are centrally symmetrically distributed around the left end surface of the connecting plate. The limiting grooves are slidably connected to the surface of the limiting rod.

[0015] The above technical solution, through the cooperation of the limiting groove and the sliding rod, limits the position of the connecting plate and the metering plate when they move, thus avoiding jamming.

[0016] As a further improvement to the above solution, the adjusting component includes a threaded sleeve, the threaded sleeve having a threaded rod internally connected to it, a push plate fixedly connected to the right end of the threaded rod, a limit sleeve fitted onto the surface of the push plate, and a handwheel fixedly connected to the left end of the threaded rod.

[0017] As a further improvement to the above solution, the threaded sleeve is fixedly connected to the inner center of the connecting disc, and the left end of the limiting sleeve is fixedly connected to the left end of the metering disc.

[0018] Through the above technical solution, by fixing the threaded sleeve to the center of the connecting plate and the limiting sleeve to the end face of the metering plate, the rotational motion of the threaded rod during operation is converted into the pure axial movement of the metering plate through the push plate and the limiting sleeve, without the transmission of additional torque, thus achieving the effects of labor-saving adjustment and self-locking positioning.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model incorporates a hydraulic telescopic rod, a limiting cylinder, a metering disc, and an inclined metering cylinder. During operation, the hydraulic telescopic rod pushes the limiting cylinder to slide along the inner wall of the metering cylinder, forming a metering cavity with a fixed volume between the limiting cylinder and the metering disc. As the process continues, the entire cavity is moved to the top of the hopper to complete the discharge, achieving quantitative discharge for single-batch material packaging.

[0020] This utility model, by setting an adjusting component consisting of a threaded sleeve, a threaded rod, a push plate, a limiting sleeve, and a handwheel, allows the threaded rod to move axially within the threaded sleeve when the handwheel is rotated during operation. This, in turn, pushes the quantitative disc to slide back and forth relative to the connecting disc, changing the axial distance between the quantitative disc and the limiting cylinder. This achieves the effect of stepless adjustment of the single batch feeding amount without stopping the machine and adapting to the needs of multiple packaging specifications.

Detailed Implementation

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example: Please combine Figure 1-4The quantitative feeding structure of a ternary precursor packaging device in this embodiment includes a base 1, an mounting plate 2 fixedly connected to the top of the base 1, a quantitative cylinder 3 fixedly installed inside the mounting plate 2, a feeding hopper 4 fixedly connected to the top of the quantitative cylinder 3, an mounting platform 5 fixedly connected to the top of the base 1, a hydraulic telescopic rod 6 installed inside the mounting platform 5, a limiting cylinder 7 fixedly connected to the output end of the hydraulic telescopic rod 6, a connecting rod 8 fixedly connected to the left end of the limiting cylinder 7, a connecting plate 9 fixedly connected to the left end of the connecting rod 8, a quantitative plate 10 fixedly connected to the connecting plate 9 through an adjusting component, and a feeding hopper 11 fixedly connected to the bottom of the quantitative cylinder 3.

[0025] In use, the hydraulic telescopic rod 6 is activated. The output end of the hydraulic telescopic rod 6 drives the limiting cylinder 7 to move. The connecting rod 8, which is fixedly connected to the limiting cylinder 7, and the connecting plate 9 move synchronously. During the movement, the limiting cylinder 7 closes the output end of the feed hopper 4, preventing the material from falling. The material between the metering plate 10 and the limiting cylinder 7 gradually approaches the lower hopper 11 under the push of the hydraulic telescopic rod 6 until the limiting cylinder 7 passes above the lower hopper 11. At this time, the material between the metering plate 10 and the limiting cylinder 7 is discharged from the lower hopper 11.

[0026] The distance between the metering cylinder 3 and the bottom of the base 1 gradually increases from left to right. The surface of the limiting cylinder 7 is in contact with the inner wall of the limiting cylinder 7. By setting the angle between the axis of the metering cylinder and the bottom surface of the base to gradually increase from left to right, the material automatically slides to the left and fills the metering chamber under its own weight during operation, without the need for additional vibration or air blowing.

[0027] There are two connecting rods 8, which are arranged in a circular array on the left end surface of the limiting cylinder 7. By arranging the two connecting rods in a circular array on the left end surface of the limiting cylinder, the thrust is symmetrically transmitted to the connecting plate and the metering plate during operation, avoiding jamming and uneven wear caused by unilateral force.

[0028] The connecting plate 9 and the metering plate 10 are concentric, and the surfaces of both the connecting plate 9 and the metering plate 10 are slidably connected to the inner wall of the metering cylinder 3.

[0029] A limiting groove 12 is formed on the surface of the connecting plate 9, and a limiting rod 13 is fixedly connected to the inner wall of the metering cylinder 3.

[0030] There are two limiting grooves 12. The two limiting grooves 12 are centrally symmetrically distributed on the left end surface of the connecting plate 9. The limiting grooves 12 are slidably connected to the surface of the limiting rod 13.

[0031] The adjusting component includes a threaded sleeve 14, with a threaded rod 15 internally threadedly connected to the threaded sleeve 14. A push plate 16 is fixedly connected to the right end of the threaded rod 15, and a limit sleeve 17 is fitted onto the surface of the push plate 16. A handwheel 18 is fixedly connected to the left end of the threaded rod 15.

[0032] The threaded sleeve 14 is fixedly connected to the inner center of the connecting disc 9, and the left end of the limiting sleeve 17 is fixedly connected to the left end of the metering disc 10.

[0033] The implementation principle of the quantitative feeding structure of a ternary precursor packaging device in this application embodiment is as follows: When packaging ternary precursors, the ternary precursors are first fed into the feed hopper 4 and enter the interior of the quantitative cylinder 3 through the output end of the feed hopper 4. Since the distance between the quantitative cylinder 3 and the bottom of the base 1 gradually increases from left to right, the ternary precursors slide to the left inside the quantitative cylinder 3 after entering it and contact the right end of the quantitative disc 10. When the ternary precursors fill the space between the quantitative disc 10 and the limiting cylinder 7, the hydraulic telescopic rod 6 is activated, and the output of the hydraulic telescopic rod 6... The end drives the limiting cylinder 7 to move, and the connecting rod 8 and connecting plate 9, which are fixedly connected to the limiting cylinder 7, move synchronously. During the movement, the limiting cylinder 7 closes the output end of the feed hopper 4, preventing the material from falling. The material between the metering plate 10 and the limiting cylinder 7 gradually approaches the lower hopper 11 under the push of the hydraulic telescopic rod 6, until the limiting cylinder 7 passes above the lower hopper 11. At this time, the material between the metering plate 10 and the limiting cylinder 7 is discharged from the lower hopper 11. Then the hydraulic telescopic rod 6 retracts, the limiting cylinder 7 disengages from the output end of the feed hopper 4, and the material continues to fall for the next batch of work.

[0034] By rotating the threaded rod 15 through the handwheel 18, the threaded rod 15 rotates inside the threaded sleeve 14. This threaded rod 15 pushes the push plate 16 to move the metering disc 10 back and forth, so as to limit the distance between the metering disc 10 and the limiting cylinder 7, and quantitatively control the conveying and packaging of a single batch of materials.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
