Description

Technical Field

[0001] This utility model relates to the technical field of lubricant filling, and in particular to a lubricant filling and metering device. Background Technology

[0002] Lubricant filling refers to the process of automatically or semi-automatically injecting liquid or semi-solid lubricants into packaging containers according to a predetermined volume using specialized equipment. It typically includes stages such as raw material preparation, metering, filling, sealing, and inspection. Modern filling equipment employs sophisticated sensors, servo control systems, and anti-drip technology, enabling efficient and precise dispensing of lubricants of varying viscosities while ensuring no contamination or leakage during the filling process. It is widely used in the automotive, machinery, and industrial production sectors.

[0003] Current lubricant filling and metering equipment commonly suffers from inconvenient filling volume adjustment in practical applications. This is especially true when dealing with production needs for containers of varying sizes, where the adjustment process is often cumbersome, requiring significant time and manpower, thus impacting production efficiency. While some equipment employs electrically controlled valves for precise metering, this significantly increases system complexity and overall cost, leading to higher production costs and hindering its adoption by small and medium-sized enterprises. Therefore, simplifying the filling volume adjustment process and reducing equipment costs while maintaining filling accuracy has become a pressing technical challenge in the field of lubricant filling technology. Utility Model Content

[0004] In view of the contradiction between the cumbersome filling volume adjustment and the high cost of the existing lubricant filling equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a lubricant filling and metering device, which aims to solve the contradiction between the cumbersome filling volume adjustment and the high cost of the electrical control scheme in existing lubricant filling equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lubricant filling and metering device, including a fixed support and a container, and further including a quantitative extrusion mechanism and an adjustment mechanism. The container is fixedly installed in the upper part of the fixed support, and the quantitative extrusion mechanism includes an extrusion block rotatably installed in the upper part of the container. An extrusion plate is movably installed inside the container. The adjustment mechanism includes a telescopic groove formed inside the extrusion block, a telescopic block slidably installed inside the telescopic groove, a rack fixedly installed on the inner side of the telescopic block, a first gear rotatably installed inside the telescopic groove, a second gear meshing on one side of the first gear, and a handwheel fixedly installed on one side surface of the second gear.

[0007] In a preferred embodiment of the lubricant filling and metering equipment of this utility model, a fixed tube is fixedly installed on one side surface of the container, a telescopic tube is fixedly installed at the lower end of the fixed tube, and the telescopic tube is fixedly installed on the surface of the extrusion plate.

[0008] In a preferred embodiment of the lubricant filling and metering equipment of this utility model, a drive motor is fixedly installed on one side surface of the container, a drive shaft is driven at the output end of the drive motor, and the extrusion block is fixedly installed on the surface of the drive shaft.

[0009] In a preferred embodiment of the lubricant filling and metering equipment of this utility model, a fixing block is fixedly installed on the lower part of both sides of the container, a sliding rod is fixedly installed on the upper surface of the fixing block, a connecting rod is slidably installed on the surface of the sliding rod, and one end of the connecting rod is fixedly installed on the upper surface of the extrusion plate.

[0010] In a preferred embodiment of the lubricant filling and metering device of this utility model, a stop block is fixedly installed at the upper end of the slide rod, and a spring structure is installed between the lower surface of the connecting rod and the upper surface of the fixed block.

[0011] In a preferred embodiment of the lubricant filling and metering device of this utility model, the first gear and the rack mesh with each other, a limiting groove is formed on the inner side of the telescopic groove, a limiting rod is fixedly installed inside the limiting groove, a limiting block is slidably installed on the surface of the limiting rod, and the limiting block is fixedly installed on one side surface of the rack.

[0012] In a preferred embodiment of the lubricant filling and metering device of this utility model, positioning holes are provided on the surface of the handwheel and the surface of the extrusion block, and positioning pins are inserted into the interior of the positioning holes.

[0013] In a preferred embodiment of the lubricant filling and metering equipment described in this utility model, an extrusion head is fixedly installed at the lower end of the container.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its extrusion mechanism, enables the drive motor to rotate the extrusion block via a transmission shaft during quantitative filling of lubricant. The elliptical extrusion block continuously presses the extrusion plate downwards through the telescopic blocks at both ends. The extrusion plate quantitatively extrudes the lubricant from the container through the extrusion head. Subsequently, the spring structure's restoring force pulls the connecting rod and extrusion plate upwards. Simultaneously, the negative pressure within the container draws lubricant from the fixed tube into the container, ensuring the container remains full. This not only precisely controls the extrusion volume each time but also utilizes automatic replenishment under negative pressure to ensure the container is always filled with lubricant, effectively preventing air bubbles and significantly improving filling efficiency and finished product quality.

[0015] 2. This utility model, through its adjustable mechanism, allows for convenient and rapid adjustment of the filling volume when the lubricant dosage needs to be adjusted. By pulling the positioning pin out of the positioning hole and rotating the handwheel, the second gear rotates, which in turn rotates the first gear. This causes the rack and telescopic block to retract inward or extend outward within the telescopic groove, thereby controlling the pressure of the extrusion block on the extrusion plate. The operator only needs to pull out the positioning pin and rotate the handwheel to precisely change the stroke of the extrusion block, easily adapting to the filling needs of different containers. The entire process requires no complex electrical control system, significantly reducing equipment costs, simplifying the operation process, and improving production flexibility.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a lubricant filling and metering device. This lubricant filling and metering device includes a fixed support 1 and a container 2, and also includes a quantitative extrusion mechanism 4 and an adjustment mechanism 5. The container 2 is fixedly installed in the upper part of the fixed support 1. The quantitative extrusion mechanism 4 includes an extrusion block 403 rotatably installed in the upper part of the container 2. An extrusion plate 411 is movably installed inside the container 2.

[0020] A fixed tube 404 is fixedly installed on one side surface of container 2, and a telescopic tube 405 is fixedly installed at the lower end of the fixed tube 404. The telescopic tube 405 is fixedly installed on the surface of the extrusion plate 411.

[0021] A drive motor 401 is also fixedly installed on one side surface of container 2. A drive shaft 402 is driven and installed at the output end of drive motor 401, and extrusion block 403 is fixedly installed on the surface of drive shaft 402.

[0022] Fixing blocks 406 are fixedly installed on the lower part of both sides of container 2. Sliding rods 407 are fixedly installed on the upper surface of fixing blocks 406. Connecting rods 409 are slidably installed on the surface of sliding rods 407. One end of connecting rods 409 is fixedly installed on the upper surface of extrusion plate 411.

[0023] A stop 408 is fixedly installed at the upper end of the slide rod 407, and a spring structure 410 is installed between the lower surface of the connecting rod 409 and the upper surface of the fixing block 406.

[0024] During use, the drive motor 401 is started, and its output end drives the extrusion block 403 to rotate in the upper part of the container 2 via the transmission shaft 402. When the major axis of the ellipse of the extrusion block 403 rotates downward, it pushes the extrusion plate 411 to slide downward along the slide rod 407, while compressing the spring structure 410. As the extrusion plate 411 moves downward, the lubricant in the fixed tube 404 moves downward along with it through the telescopic tube 405 fixed on its surface, thereby extruding the lubricant in the container 2 from the extrusion head 3 at the lower end, completing one quantitative filling. Subsequently, when the extrusion block 403 continues to rotate until the minor axis of the ellipse faces downward, the extrusion plate 411 loses its downward thrust, and the compressed spring structure 410 releases its restoring force, pulling the extrusion plate 411 upward through the connecting rod 409. When the extrusion plate 411 moves upward, a negative pressure is formed inside the container 2. This negative pressure draws external lubricant into the container 2 through the fixed tube 404 and the telescopic tube 405, preparing for the next filling. This cycle repeats to achieve continuous automated filling operations. Example 2

[0025] Reference Figures 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adjusting mechanism 5 includes a telescopic groove 501 opened inside the extrusion block 403, a telescopic block 502 is slidably installed inside the telescopic groove 501, a rack 503 is fixedly installed on the inner side of the telescopic block 502, a first gear 504 is rotatably installed inside the telescopic groove 501, a second gear 505 is meshed on one side of the first gear 504, and a handwheel 506 is fixedly installed on one side surface of the second gear 505.

[0026] The first gear 504 and the rack 503 mesh with each other. A limiting groove 509 is opened on the inner side of the telescopic groove 501. A limiting rod 510 is fixedly installed inside the limiting groove 509. A limiting block 511 is slidably installed on the surface of the limiting rod 510. The limiting block 511 is fixedly installed on one side surface of the rack 503.

[0027] Both the surface of the handwheel 506 and the surface of the extrusion block 403 are provided with positioning holes 507, and positioning pins 508 are inserted into the positioning holes 507.

[0028] An extrusion head 3 is fixedly installed at the lower end of container 2.

[0029] During use, when the filling volume needs to be adjusted according to different containers 2, first pull out the positioning pin 508 in the positioning hole 507 aligned with the handwheel 506 on the extrusion block 403. Then rotate the handwheel 506, which drives the second gear 505 to rotate, and the second gear 505 in turn meshes with and drives the first gear 504 to rotate. The first gear 504 meshes with the rack 503, driving the rack 503 and its fixed telescopic block 502 to slide linearly within the telescopic groove 501 of the extrusion block 403. The telescopic block 502 retracts inward or extends outward, changing the overall rotation radius of the extrusion block 403, that is, changing its maximum downward stroke on the extrusion plate 411, thereby realizing the adjustment of the single filling volume. After the adjustment is completed, re-insert the positioning pin 508 into the aligned positioning hole 507 for locking. During this process, the limit block 511 slides along the limit rod 510 within the limit groove 509, ensuring the stability of the rack 503's movement and preventing it from deflecting.

[0030] The remaining structure is the same as that in Example 1.

[0031] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the drive motor 401 is started, which drives the extrusion block 403 to rotate in the upper part of the container 2 via the transmission shaft 402. When the major axis of the ellipse of the extrusion block 403 rotates downward, it pushes the extrusion plate 411 to slide downward along the slide rod 407, while compressing the spring structure 410. When the extrusion plate 411 moves downward, the lubricant in the fixed tube 404 moves downward along with it through the telescopic tube 405 fixed on its surface, thereby extruding the lubricant in the container 2 from the extrusion head 3 at the lower end, completing one quantitative filling. Subsequently, when the extrusion block 403 continues to rotate until the minor axis of the ellipse faces downward, the extrusion plate 411 loses its downward thrust, and the compressed spring structure 410 releases its restoring force, pulling the extrusion plate 411 upward through the connecting rod 409. When the extrusion plate 411 moves upward, a negative pressure is formed inside the container 2. This negative pressure draws external lubricant into the container 2 through the fixed tube 404 and the telescopic tube 405, preparing for the next filling. This cycle repeats continuously, achieving automated filling operations. When it is necessary to adjust the filling volume according to different containers 2, the positioning pin 508 can be pulled out and the handwheel 506 can be turned. The handwheel 506 drives the second gear 505 to mesh with the first gear 504, thereby driving the rack 503 and its fixed telescopic block 502 to slide in the telescopic groove 501 of the extrusion block 403. By changing the effective rotation radius of the extrusion block 403, its downward pressure stroke on the extrusion plate 411 can be adjusted, thereby precisely controlling the single filling volume. After adjustment, the positioning pin 508 can be reinserted and locked.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
