Description

Technical Field

[0001] This utility model relates to the field of oil storage technology, specifically to an oil filling vacuum sealing device. Background Technology

[0002] Oil filling vacuum sealing equipment is a device specifically designed to achieve vacuum sealing during the oil filling process. It is widely used in oil filling production lines in industries such as petroleum, chemical, and daily chemicals. It is suitable for filling and sealing various liquid products such as lubricating oil, edible oil, and cosmetics. By using this equipment, companies can greatly improve production efficiency and product quality, and reduce production costs and waste.

[0003] An oil filling device, application number CN202322489975.2, includes a piston assembly slidably disposed within a filling pipe, in conjunction with a rotating baffle assembly and an elastic component. During filling, the piston body descends, first opening multiple baffle bodies, then connecting the oil outlet channel to the oil inlet pipe for filling. After filling, the piston body rises and disconnects from the oil outlet pipe, ceasing to open the multiple baffle bodies, allowing the baffle assembly to automatically seal the bottom opening of the filling pipe, preventing dust from entering and oil from dripping. An upper and lower stepped surface on the inner wall of the filling pipe cooperates with an upper and lower sealing surface on the piston body. When filling stops, the surfaces press together, and a sealing gasket can be added to achieve a better sealing effect. This solves the problem in existing oil filling devices where leakage and dust adhesion to the pipe opening easily occur after shutdown.

[0004] However, the sealing gasket of this device needs to be sealed manually, which is cumbersome and can easily affect the sealing performance of the tank, thus affecting its use.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing structure of vacuum sealing equipment for oil filling. Utility Model Content

[0006] The purpose of this utility model is to provide an oil filling vacuum sealing device to solve the problem in the background art that the sealing gasket of the device needs to be manually sealed, which is cumbersome to operate and can easily affect the sealing performance of the tank, thus affecting the use of the tank.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oil filling vacuum sealing device, comprising a tank body, wherein a feed inlet is fixedly installed on the outside of the tank body; further comprising a sealing component connected to the bottom of the feed inlet; and a dustproof component connected to the top of the feed inlet; wherein the sealing component is used to seal the bottom of the feed inlet; and the dustproof component is used to prevent dust from entering the top of the feed inlet.

[0008] Preferably, the sealing assembly includes a sliding sleeve, a sliding rod, and a sealing ring. The sliding sleeve is fitted on the outside of the feed inlet, and the sliding rod is fixedly connected to the bottom of the sliding sleeve. The sliding rod is slidably connected to the inside of the tank.

[0009] Preferably, the sealing assembly further includes a first telescopic spring, the two ends of which are respectively connected to the bottom of the sliding ring and the outer wall of the tank.

[0010] Preferably, the sealing assembly further includes a sliding track, a second telescopic spring, and a sliding block. The sliding track is fixedly installed on the outside of the tank, and the second telescopic spring is fixedly connected to the inside of the sliding track. The tail end of the second telescopic spring is fixedly connected to the sliding block, and the sliding block is slidably connected to the inside of the sliding track.

[0011] Preferably, the sealing assembly further includes a limiting block, which is fixedly connected to the upper end of the sliding block, and the limiting block and the sliding ring are distributed in a left-right correspondence, with the left side of the limiting block having an oblique opening when viewed from the front.

[0012] Preferably, the dustproof component includes a rack, which is fixedly installed on the upper end of the limiting block.

[0013] Preferably, the dustproof assembly further includes a fixing plate, a concentric shaft, a cover plate, a dustproof sleeve, and a gear. The fixing plate is fixedly installed on the upper end of the tank, and the concentric shaft is rotatably connected to the inner side of the fixing plate. The cover plate is fixedly connected to the outer side of the concentric shaft, and the dustproof sleeve is fixedly connected to the bottom of the cover plate. The gear is fixedly connected to the outer side of the concentric shaft, and the gear meshes with a rack.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the oil filling vacuum sealing equipment is equipped with:

[0015] 1. Sealing structure: When the tank needs to be filled with oil, manually push the limiting block to the left. When the limiting block moves to the left, the inclined opening on the left side of the limiting block will press the sliding ring on the outside of the feed port to slide downward. As the sliding ring slides downward, it will drive the sealing ring at the end of the sliding rod to slide downward as well, thereby separating the sealing ring from the bottom of the feed port, making the bottom of the feed port open, which is convenient for filling oil into the inside of the tank.

[0016] Furthermore, once the tank is filled with oil, the limiting block is released. The sliding block at the bottom of the limiting block is reset by the elastic force of the second telescopic spring, causing the limiting block to move to the right. As the limiting block moves to the right, the sliding ring loses the pressure of the limiting block and is reset by the elastic force of the first telescopic spring. This causes the sealing ring at the bottom of the sliding rod to move upward and fit against the bottom of the inlet, sealing the bottom of the inlet and preventing oil leakage from the inside of the tank.

[0017] 2. Dustproof structure: When the limiting block moves to the right, the rack at its upper end also moves along with it. As the rack moves, it drives the outer meshing gear to rotate. The rotation of the gear drives the concentric shaft to rotate as well, thus making the cover plate rotate into a vertical position for easy oil filling. After oil filling is completed, the limiting block is released. When the limiting block moves to the right, the rack also resets, thus driving the gear to rotate in the opposite direction. Through the reverse rotation of the gear, the cover plate rotates along with it, so that the dustproof sleeve at the bottom of the cover plate fits onto the upper end of the feed inlet, preventing dust from adhering to the inner pipe of the feed inlet and affecting the quality of the oil.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution: an oil filling vacuum sealing device, comprising:

[0027] Example 1: As Figures 1-4 The present invention provides a technical solution: an oil filling vacuum sealing device, comprising: a tank body 1, with an inlet 2 fixedly installed on the outside of the tank body 1; a sealing component 3 connected to the bottom of the inlet 2; and a dustproof component 4 connected to the top of the inlet 2; wherein the sealing component 3 is used to seal the bottom of the inlet 2; and the dustproof component 4 is used to prevent dust from entering the top of the inlet 2.

[0028] The sealing assembly 3 includes a sliding sleeve 301, a sliding rod 302, and a sealing ring 303. The sliding sleeve 301 is fitted onto the outside of the feed inlet 2, and the sliding rod 302 is fixedly connected to the bottom of the sliding sleeve 301. The sliding rod 302 is slidably connected to the inside of the tank body 1. The sealing assembly 3 also includes a first telescopic spring 304, with its two ends connected to the bottom of the sliding sleeve 301 and the outer wall of the tank body 1, respectively. The sealing assembly 3 also includes a sliding track 305, a second telescopic spring 306, and a sliding block. 307, the sliding rail 305 is fixedly installed on the outside of the tank body 1, and a second telescopic spring 306 is fixedly connected to the inside of the sliding rail 305. A sliding block 307 is fixedly connected to the tail end of the second telescopic spring 306, and the sliding block 307 is slidably connected to the inside of the sliding rail 305; the sealing assembly 3 also includes a limiting block 308, the limiting block 308 is fixedly connected to the upper end of the sliding block 307, and the limiting block 308 and the sliding collar 301 are distributed in a left-right correspondence. The left side of the limiting block 308 is obliquely shaped when viewed from the front.

[0029] When oil needs to be added to tank 1, the limiting block 308 is manually pushed to the left. As the limiting block 308 moves to the left, the angled opening on the left side of the limiting block 308 presses down on the sliding ring 301 on the outside of the feed inlet 2. As the sliding ring 301 slides downwards, it causes the sealing ring 303 at the end of the sliding rod 302 to slide downwards as well, thus separating the sealing ring 303 from the bottom of the feed inlet 2. This opens the bottom of the feed inlet 2, facilitating oil injection into the tank 1. When the oil inside the tank 1... After filling, release the limiting block 308. The sliding block 307 at the bottom of the limiting block 308 is reset by the elastic force of the second telescopic spring 306, thereby causing the limiting block 308 to move to the right. As the limiting block 308 continues to move to the right, the sliding ring 301 loses the pressure of the limiting block 308 and is reset by the elastic force of the first telescopic spring 304, thereby causing the sealing ring 303 at the bottom of the sliding rod 302 to move upward and fit against the bottom of the feed inlet 2, sealing the bottom of the feed inlet 2 and preventing oil leakage from the inside of the tank 1.

[0030] Example 2: Figures 1-2 , Figures 5-6 The present invention provides a technical solution: an oil filling vacuum sealing device, which discloses that: the dustproof component 4 includes a rack 401, which is fixedly installed on the upper end of the limiting block 308; the dustproof component 4 also includes a fixing plate 402, a concentric shaft 403, a cover plate 404, a dustproof sleeve 405 and a gear 406, the fixing plate 402 is fixedly installed on the upper end of the tank body 1, and the concentric shaft 403 is rotatably connected to the inner side of the fixing plate 402, the cover plate 404 is fixedly connected to the outer side of the concentric shaft 403, and the dustproof sleeve 405 is fixedly connected to the bottom of the cover plate 404; the gear 406 is fixedly connected to the outer side of the concentric shaft 403, and the gear 406 meshes with the rack 401;

[0031] When the limiting block 308 moves to the right, the rack 401 at its upper end also moves along with it. As the rack 401 moves, it drives the outer meshing gear 406 to rotate. The rotation of the gear 406 drives the concentric shaft 403 to rotate along with it, thereby making the cover plate 404 rotate to a vertical position for easy oil filling. After oil filling is completed, the limiting block 308 is released. When the limiting block 308 moves to the right, the rack 401 also resets along with it, thereby driving the gear 406 to rotate in the opposite direction. Through the reverse rotation of the gear 406, the cover plate 404 is driven to rotate along with it, so that the dust cover 405 at the bottom of the cover plate 404 fits onto the upper end of the feed inlet 2, preventing dust from adhering to the inner pipe of the feed inlet 2 and affecting the quality of the oil.
