Description

Technical Field

[0001] This utility model relates to the field of milk powder filling technology, specifically to a nozzle mechanism for a fully automatic milk powder filling machine. Background Technology

[0002] Currently, canned milk powder is usually filled in quantitatively using fully automatic filling machines. During filling, the conveyor belt transports the empty milk powder cans to the area directly below the syringe. Then, the syringe fills the milk powder in the hopper into the milk powder can. In order to eliminate the height difference between the syringe and the milk powder can, a liftable guide tube is usually installed at the bottom of the syringe to prevent milk powder from splashing due to the height difference.

[0003] For example, the utility model patent with publication number CN210364455U discloses a nozzle mechanism for a fully automatic milk powder filling machine. In use, this mechanism uses a lifting tube to lower a dust cover, which then covers the milk powder can opening, thus preventing splashing.

[0004] However, during the filling process, some powder tends to stick to the lower surface of the dust cover. Since the dust cover of this mechanism is fixedly connected to the lifting pipe and cannot be disassembled, it is inconvenient to clean the dust cover. Utility Model Content

[0005] In view of this, the present invention provides a nozzle mechanism for a fully automatic milk powder filling machine, which aims to solve the technical problem that the lifting pipe and dust cover in the existing nozzle mechanism cannot be disassembled, making it inconvenient to clean the dust cover.

[0006] To solve the above-mentioned technical problems, this utility model provides a nozzle mechanism for a fully automatic milk powder filling machine, including a feeding pipe, a lifting pipe, and a dust cover. The feeding pipe is connected to the discharge port of the filling machine. The lifting pipe is vertically slidably sleeved on the feeding pipe. The dust cover is vertically slidably mounted on the lifting pipe. The inner wall of the dust cover has a radially formed movable groove. A quick-release mechanism is provided in the movable groove. The quick-release mechanism includes a movable block and a toggle component. The movable block and the movable groove slide in a radial engagement with the lifting pipe. The outer wall of the lifting pipe has a vertically formed guide groove. One end of the movable block is connected to the toggle component in the movable groove. The other end of the movable block can extend radially out of the movable groove along the lifting pipe and slide into the guide groove, with the movable block and the guide groove sliding in a vertical engagement. The toggle component is used to drive the movable block to slide radially along the lifting pipe, causing the movable block to disengage from or insert into the guide groove.

[0007] Furthermore, the actuating component includes a connecting block, a fixing block, and a lever. The connecting block is slidably adapted to the movable groove. The movable block is fixedly connected to the side of the connecting block facing the guide groove. The fixing block is fixedly disposed at the lower end of the connecting block. A through groove is radially formed on the lower wall surface of the dust cover corresponding to the position of the fixing block. The fixing block is slidably adapted to the through groove. The lever is fixedly disposed at the lower end of the fixing block and is located below the through groove.

[0008] Furthermore, the actuating component also includes an elastic element, which is disposed on the side of the connecting block facing away from the movable block.

[0009] Furthermore, the movable groove extends through the lower wall of the dust cover, and a sealing cover is detachably connected to the lower wall of the dust cover corresponding to the movable groove, with the through groove being opened on the sealing cover.

[0010] Furthermore, the toggle block covers the through groove, and the toggle block is slidable relative to the sealing cover.

[0011] Furthermore, extension blocks are provided on both sides of the sealing cover, and slots are opened on the lower wall of the dust cover corresponding to the parts of each extension block. Each extension block is respectively accommodated in the corresponding slot. A through hole is opened vertically on the surface of the extension block, and a threaded hole is opened vertically on the inner wall of the slot. The threaded hole is coaxially corresponding to the through hole. A threaded locking member is inserted into the through hole, and the threaded locking member is threadedly engaged with the threaded hole.

[0012] Furthermore, the movable block extends radially from the through hole of the movable groove along the lifting tube. The inner diameter of the through hole of the movable groove is smaller than the outer diameter of the connecting block, but larger than the outer diameter of the movable block.

[0013] Furthermore, there are two guide grooves, which are symmetrically distributed on both sides of the outer wall of the lifting pipe.

[0014] Furthermore, the upper end of the feeding tube is provided with a fixing plate, and two driving components are installed on both sides of the lower surface of the fixing plate. The upper end of the lifting tube is provided with a connecting plate, and both driving components are connected to the connecting plate. The driving components drive the connecting plate and the lifting tube to slide up and down.

[0015] Furthermore, the lower end of the feeding pipe is provided with a scraper, the end of which abuts against the inner wall of the lifting pipe, and the scraper can slide vertically relative to the lifting pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the nozzle mechanism of this utility model, if the dust cover needs to be removed for replacement or cleaning, the operator pulls the movable block by a lever, causing the movable block to slide radially away from the guide groove. This allows the end of the movable block to completely exit the guide groove of the lifting pipe, thus detaching the dust cover from the lifting pipe and allowing the dust cover to be removed downwards. During installation, the dust cover is slipped back onto the lifting pipe, and the movable block is aligned with the guide groove. The lever is then used to insert the movable block into the guide groove, restoring the sliding connection between the two. This achieves a detachable connection between the dust cover and the lifting pipe, facilitating the removal of the dust cover from the lifting pipe for cleaning. Attached Figure Description

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through other features. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] Please refer to Figures 1-8 This utility model provides a nozzle mechanism for a fully automatic milk powder filling machine, including a feeding pipe 100, a lifting pipe 200, and a dust cover 300. The dust cover 300 has a ring structure. The feeding pipe 100 is vertically connected to the discharge port of the filling machine to serve as the main channel for powder outflow. The lifting pipe 200 is sleeved on the outside of the feeding pipe 100 in a vertically slidable manner. The dust cover 300 is vertically slidably mounted on the lifting pipe 200. The inner ring wall of the dust cover 300 has a movable groove 400, which extends radially along the lifting pipe 200, and the opening of the movable groove 400 penetrates the inner ring wall of the dust cover 300. A quick-release mechanism is provided in the movable groove 400.

[0024] The quick-release mechanism includes a movable block 401 and a toggle component.

[0025] Reference Figures 1-3The movable block 401 and the movable groove 400 slide together radially along the lifting tube 200. A guide groove 201 is vertically formed on the outer wall of the lifting tube 200. When the dust cover 300 and the lifting tube 200 are assembled, one end of the movable block 401 is connected to the actuating component located in the movable groove 400, and the other end of the movable block 401 extends radially through the movable groove 400 and slides into the guide groove 201, allowing the dust cover 300 to slide up and down relative to the lifting tube 200. The actuating component drives the movable block 401 to slide radially along the lifting tube 200, causing the movable block 401 to disengage from or insert into the guide groove 201, thereby enabling rapid separation or assembly of the dust cover 300 and the lifting tube 200.

[0026] When the dust cover 300 needs to be removed for replacement or cleaning, the operator pulls the movable block 401 using the actuating component, causing the movable block 401 to slide radially away from the guide groove 201 along the lifting pipe 200. This allows the end of the movable block 401 to completely exit the guide groove 201 of the lifting pipe 200, thus disengaging the dust cover 300 from the lifting pipe 200 and allowing the dust cover 300 to be removed downwards. During installation, the dust cover 300 is slipped back onto the lifting pipe 200, and the movable block 401 is aligned with the guide groove 201. The actuating component then drives the movable block 401 into the guide groove 201, restoring the sliding connection between the two. This achieves a detachable connection between the dust cover 300 and the lifting pipe 200, facilitating the removal of the dust cover 300 from the lifting pipe 200 for cleaning.

[0027] Reference Figure 2 and Figure 3 The actuating component includes a connecting block 402, a fixing block 403, and a toggle block 404.

[0028] Specifically, the connecting block 402 is slidably adapted to the movable groove 400, and the cross-sections of the connecting block 402 and the movable groove 400 are rectangular structures that are adapted to each other. The movable block 401 is fixedly connected to the side wall of the connecting block 402 facing the guide groove 201. The fixed block 403 is fixedly installed at the lower end of the connecting block 402. The lower wall of the dust cover 300 is provided with a through groove 405 corresponding to the position of the fixed block 403. The through groove 405 is connected to the movable groove 400 and extends radially along the lifting tube 200. The fixed block 403 is slidably adapted to the through groove 405. The toggle block 404 is fixedly installed at the lower end of the connecting block 402 and is located below the through groove 405.

[0029] The operator uses their finger to move the exposed lever 404, which causes the connecting block 402 to move within the movable slot 400. The connecting block 402, in turn, causes the movable block 401 and the fixed block 403 on it to move together, thereby allowing the movable block 401 to insert into or detach from the guide slot 201, thus achieving the connection and separation of the dust cover 300 and the lifting pipe 200.

[0030] Reference Figure 3 The actuating component also includes an elastic element 406, which is disposed on the side of the connecting block 402 facing away from the movable block 401. When the movable block 401 is inserted into the guide groove 201, the elastic force of the elastic element 406 continuously pushes the connecting block 402 towards the central axis of the lifting tube 200, thus stably holding the movable block 401 in the locked position inserted into the guide groove 201. Only when the operator applies external force to actuate the actuating block 404 to overcome the elastic force will the movable block 401 disengage from the guide groove 201, thus providing the movable block 401 with automatic reset and self-locking functions. This ensures that during normal operation, the movable block 401 will not accidentally disengage from the guide groove 201 due to vibration, guaranteeing the robustness of the dust cover 300 connection. In this embodiment, the elastic element 406 is preferably a spring; other elastic structures may be selected in other embodiments, and are not limited here.

[0031] Reference Figure 5 , Figure 6 and Figure 7 The movable groove 400 penetrates the lower wall of the dust cover 300, connecting the movable groove 400 to the outside. A sealing cover 407 is detachably connected to the lower wall of the dust cover 300 corresponding to the movable groove 400, and a through groove 405 is opened on the sealing cover 407. When it is necessary to replace the elastic element 406, the sealing cover 407 can be removed from the lower wall of the dust cover 300 to expose the movable groove 400, so that the elastic element 406 inside the movable groove 400 can be taken out and replaced, thereby improving the service life of the quick-release mechanism.

[0032] Reference Figure 3 and Figure 5 The lever 404 extends radially along the lifting tube 200 to cover the through groove 405, and the lever 404 is slidable relative to the sealing cover 407. When the movable block 401 is inserted into the guide groove 201, the lever 404 can cover the underside of the through groove 405 to prevent dust from entering from the through groove 405 and accumulating in the movable groove 400 and other mechanisms.

[0033] Reference Figure 7The sealing cover 407 has extension blocks 408 extending radially along the lifting tube 200 on both sides. Corresponding slots 301 are provided on the lower wall of the dust cover 300 at locations corresponding to each extension block 408, and each extension block 408 is accommodated within its corresponding slot 301. A through hole is vertically formed on the surface of the extension block 408, and a threaded hole 302 is vertically formed on the inner wall of the slot 301. The threaded hole 302 is coaxially aligned with the through hole, and a threaded locking element 409 is inserted into the through hole, threadedly engaging with the threaded hole 302.

[0034] The operator places the extension blocks 408 on both sides of the sealing cover 407 into the slot 301, and after the sealing cover 407 covers the movable slot 400, the threaded locking member 409 is passed through the through hole and screwed into the threaded hole 302 to fix the sealing cover 407 under the dust cover 300.

[0035] Reference Figure 3 and Figure 7 The movable block 401 extends radially through the through hole 410 of the movable groove 400 along the lifting tube 200. The inner diameter of the through hole 410 of the movable groove 400 is smaller than the outer diameter of the connecting block 402 and larger than the outer diameter of the movable block 401. This allows the movable block 401 to extend or retract freely through the through hole 410, while the connecting block 402 is confined inside the movable groove 400 and cannot come out. This limits the extension range of the movable block 401 and prevents the end of the movable block 401 from being tightly pressed against the inner wall of the guide groove 201, which could cause it to slide and get stuck.

[0036] Reference Figure 2 There are two guide grooves 201, which are symmetrically distributed on both sides of the outer wall of the lifting tube 200. Correspondingly, the dust cover 300 is also equipped with two sets of quick-release mechanisms. The two sets of quick-release mechanisms cooperate with the two guide grooves 201 respectively, so that the connection between the dust cover 300 and the lifting tube 200 is more balanced and stable, preventing the dust cover 300 from deflecting or getting stuck during the lifting process, and ensuring smooth movement.

[0037] Reference Figure 1The upper end of the feeding pipe 100 is provided with a fixing plate 101, which can be installed on the frame of the filling machine. Two telescopic drive members 102 are installed on both sides of the lower surface of the fixing plate 101. The upper end of the lifting pipe 200 is provided with a connecting plate 202. The telescopic ends of the two drive members 102 are connected to the connecting plate 202. The drive members 102 drive the connecting plate 202 and the lifting pipe 200 to slide up and down. When the drive member 102 moves, it drives the connecting plate 202 and the entire lifting pipe 200 connected to it to slide up and down together. In this embodiment, the drive member 102 is an automatically controllable electric telescopic rod or cylinder in the prior art, and the two drive members 102 are of the same specification and can be synchronously controlled to open and close through the control system in the filling machine. Further details are omitted here.

[0038] The outer wall of the feed tube 100 is provided with a plurality of grooves 103 distributed in a ring. The number of grooves 103 is preferably four, and each groove 103 extends vertically. The inner wall of the connecting plate 202 is provided with a slider 203 at a position corresponding to each groove 103. The slider 203 extends radially along the lifting tube 200, and each slider 203 slides and adapts to each corresponding groove 103. This allows the connecting plate 202 to make the lifting tube 200 slide vertically up and down along the feed tube 100 through the cooperation of the slider 203 and the groove 103, making the sliding process more stable.

[0039] Reference Figure 8 The lower end face of the feeding pipe 100 is provided with a scraper 104. The outer edge of the scraper 104 is in close contact with the inner wall of the lifting pipe 200. The scraper 104 can slide vertically relative to the lifting pipe 200 with the feeding pipe 100, and the scraper 104 can deform when subjected to external force. When the lifting pipe 200 is controlled to rise and fall by the drive component 102, since the feeding pipe 100 remains relatively stationary, the scraper 104 can scrape off the powder adhering to the inner wall of the lifting pipe 200 and let it fall into the milk powder can, while keeping the inner wall of the lifting pipe 200 clean.

[0040] It is worth mentioning that the connecting plate 202 is connected to the lifting pipe 200 via a flange, making the lifting pipe 200 and the connecting pipe detachable, which makes it easy to remove the lifting pipe 200 from the connecting plate 202 for cleaning.

[0041] In summary, the working principle of this utility model is as follows: When the dust cover 300 needs to be installed on the lifting pipe 200, first move the two levers 404 away from each other. At this time, the levers 404 drive the connecting block 402 to move synchronously through the fixed block 403. The connecting block 402 drives the movable block 401 to move into the movable groove 400. During the movement, the connecting block 402 compresses the elastic element 406. After the connecting block 402 retracts into the movable groove 400, the annular dust cover 300 is inserted from below the lifting pipe 200. After the movable block 401 is aligned with the guide groove 201, release the levers 404 to allow the elastic element 406 to rebound. Push the connecting block 402 and the movable block 401 to reset, so that the movable block 401 passes through the opening of the movable groove 400 and inserts into the guide groove 201, thereby completing the connection between the dust cover 300 and the lifting pipe 200. When disassembly is required, move the lever 404 again to drive the movable block 401 to disengage from the guide groove 201, thereby detaching the connection between the dust cover 300 and the lifting pipe 200. This allows the dust cover 300 to be removed from the lifting pipe 200, making it easy to detach the dust cover 300 from the lifting pipe 200 for cleaning.

[0042] It should be noted that the filling machine is a common technical means in the existing filling field. Its specific structure can be referred to in the prior art document: CN210364455U, which will not be elaborated here.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
