Description

Technical Field

[0001] This utility model relates to the field of filling equipment, and in particular to a filling mechanism. Background Technology

[0002] After pesticide production, it needs to be filled. During the filling process, dripping may occur from the filling head, with pesticide residue falling onto the conveyor belt or bottles. This affects the workshop environment and poses a safety hazard to workers who may accidentally spill pesticide residue on the conveyor belt or bottles. Currently, a hopper for collecting pesticide residue is usually installed at the end of the filling head. While waiting to be filled, the hopper moves below the filling head to collect the pesticide residue. However, after collection, the pesticide residue on the hopper needs to be manually cleaned. If pesticide residue remains on the hopper for an extended period, it may overflow or stick to the hopper, increasing the difficulty of cleaning the hopper for workers.

[0003] CN202121189855 discloses a drip-proof discharge port for a semi-automatic filling machine used in pesticide production. The port includes a filling head with a drip-proof assembly below it. This assembly comprises a guide sleeve, a guide ring, and a receiving hopper. The guide sleeve is fixed to the filling machine by a bracket and is located below the filling head. The guide ring is fixed above the guide sleeve by a fastener. The filling head passes through the guide ring and extends into the guide sleeve. The receiving hopper engages with the lower end of the guide sleeve. A connecting rod is connected to one side of the receiving hopper. A horizontal rod is hinged to the upper end of the connecting rod and connected to the side wall of the guide ring. A telescopic rod is fixed to the side wall of the filling head between the guide ring and the guide sleeve. A slider is connected to the telescopic end of the telescopic rod and slides within a groove in the connecting rod. The groove is aligned with the length of the connecting rod. This drip-proof discharge port can collect residual liquid, but the receiving hopper needs to be cleaned periodically to prevent leakage during rotation.

[0004] The technical problem that this invention needs to solve is: how to prevent residual liquid from staying in the anti-drip unit for a long time during the filling process. Utility Model Content

[0005] The main purpose of this utility model is to provide a filling mechanism that collects residual liquid on the filling unit by setting a receiving plate, and then automatically scrapes off the residual liquid on the surface of the scraper plate by a scraper module, so as to avoid the residual liquid remaining on the scraper plate for a long time and affecting the production environment.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A filling mechanism includes a frame, a filling unit, and an anti-drip unit. The frame is equipped with a lifting unit for driving the filling unit to move up and down. The filling unit is slidably connected to the frame. The anti-drip unit includes a receiving plate, a connecting rod, and a scraping module for scraping material from the receiving plate. The receiving plate is slidably connected to the frame. The two ends of the connecting rod are hinged to the receiving plate and the filling unit, respectively. The scraping module is connected to the frame, and its end contacts the surface of the receiving plate. A conveying pipe is provided on the side of the receiving plate near the filling unit.

[0008] When the filling unit moves upward, the connecting rod drives the receiving plate to move along the bottom of the filling unit and collect the residual liquid dripping from the filling unit.

[0009] When the filling unit moves downward, the connecting rod drives the receiving plate to move away from the filling unit, and the scraping module drives the residual liquid on the receiving plate into the conveying pipe.

[0010] Preferably, the scraping module includes a scraper and a telescopic rod; one end of the telescopic rod is connected to the frame and the other end is connected to the scraper; the end of the scraper is in contact with the surface of the receiving plate.

[0011] Preferably, a spring is fitted onto the telescopic rod; one end of the spring is connected to the frame, and the other end is connected to the scraper.

[0012] Preferably, it further includes a collection unit; the receiving plate is provided with a collection groove; the end of the scraper is in contact with the surface of the collection groove; the conveying pipe is disposed in the collection groove; the conveying pipe is connected to the collection unit.

[0013] Preferably, the frame is provided with a sliding plate; the sliding plate is provided with a sliding groove for the receiving plate to slide; the sliding groove is provided with a limiting boss; the receiving plate is provided with a limiting groove; the limiting boss and the limiting groove cooperate to prevent the receiving plate from disengaging from the sliding plate.

[0014] Preferably, the filling unit includes a filling head and a movable frame connected to an external feeding mechanism; the filling head is connected to the movable frame; the movable frame is connected to the power output end of the lifting unit; the movable frame is slidably connected to the frame; and the movable frame is hinged to one end of the connecting rod.

[0015] Preferably, the lifting unit is a cylinder, a hydraulic cylinder, or a lead screw motor.

[0016] Preferably, the scraper is made of resin or rubber.

[0017] Compared with existing technologies, this solution has the following advantages:

[0018] In this case, the filling mechanism uses a lifting unit to move the filling unit downwards for filling. Simultaneously, the lifting unit moves the receiving plate away from the filling unit, allowing the filling unit to fill the bottle. During the receiving plate's movement, the scraping unit continuously contacts the plate's surface, pushing residual liquid to one side for collection. This method allows the scraping module to remove residual liquid during the receiving plate's movement, eliminating the need for manual cleaning of the scraping plate, reducing labor intensity, and ensuring a clean production environment.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] refer to Figure 1-6A filling mechanism includes a frame 1, a filling unit 2, and an anti-drip unit 3. The frame 1 is equipped with a lifting unit 4 for driving the filling unit 2 to move up and down. The filling unit 2 is slidably connected to the frame 1. The anti-drip unit 3 includes a receiving plate 31, a connecting rod 32, and a scraping module 33 for scraping material from the receiving plate 31. The receiving plate 31 is slidably connected to the frame 1. The two ends of the connecting rod 32 are hinged to the receiving plate 31 and the filling unit 2, respectively. The scraping module 33 is connected to the frame 1, and its end contacts the surface of the receiving plate 31. The receiving plate 31 is provided with a conveying pipe 311 on the side near the filling unit 2.

[0029] When the filling unit 2 moves upward, the connecting rod 32 drives the receiving plate 31 to move along the bottom of the filling unit 2 and collect the residual liquid dripping from the filling unit 2.

[0030] When the filling unit 2 is moving downwards, the connecting rod 32 drives the receiving plate 31 to move away from the filling unit 2, and the scraping module 33 drives the residual liquid on the receiving plate 31 into the conveying pipe 311.

[0031] In this embodiment, the filling mechanism can be automated with the conveying mechanism, which generally uses a conveyor belt.

[0032] The specific workflow of the filling mechanism is as follows: The frame 1 is positioned on the side of the conveying mechanism. Bottles are conveyed forward from one end of the conveying mechanism to below the filling unit 2. The lifting unit 4 drives the filling unit 2 downward, allowing it to extend into the bottle neck. The filling unit 2 then fills the bottle. Simultaneously, as the filling unit 2 moves downward, the lifting unit 4 drives one end of the connecting plate to move away from the filling unit 2, thereby causing the receiving plate 31 to move away from the filling unit 2. This prevents the receiving plate 31 from interfering with the filling process of the filling unit 2. When moving away from the filling unit 2, the scraper module 33 is always in contact with the surface of the receiving plate 31. The residual liquid on the receiving plate 31 is blocked by the scraper module 33, so that the residual liquid is pushed to the side of the receiving plate 31 closer to the filling unit 2, so that the residual liquid flows to the conveying pipe 311 for collection. After filling is completed, the lifting unit 4 drives the filling unit 2 to move upward, and at the same time drives the connecting rod 32 to move along the direction closer to the filling unit 2, so that the receiving plate 31 moves along the direction closer to the filling unit 2, and the receiving plate 31 is located below the filling unit 2.

[0033] It should be noted that when the receiving plate 31 is located below the filling unit 2, the angle between the connecting rod 32 and the receiving plate 31 is 70°. Other angles can also be set according to actual needs, but the angle between the connecting rod 32 and the receiving plate 31 is less than 90°.

[0034] Preferably, the scraping module 33 includes a scraper 331 and a telescopic rod 332; one end of the telescopic rod 332 is connected to the frame 1, and the other end is connected to the scraper 331; the end of the scraper 331 is in contact with the surface of the receiving plate 31.

[0035] In this embodiment, the extension length of the telescopic rod 332 can be adjusted to ensure that the scraper 331 can contact the surface of the receiving plate 31 at different heights, thereby improving the versatility of the scraper module 33.

[0036] Preferably, a spring 333 is fitted on the telescopic rod 332; one end of the spring 333 is connected to the frame 1, and the other end is connected to the scraper 331.

[0037] In this embodiment, a spring 333 is fitted onto the telescopic rod 332. The initial length of the spring 333 needs to be greater than the distance between the receiving plate 31 and the end of the telescopic rod 332 furthest from the receiving plate 31. This arrangement ensures that the scraper 331 remains in contact with the surface of the receiving plate 31, eliminating the need for adjustments or periodic checks by the operator and reducing their workload.

[0038] Preferably, it also includes a collection unit 5; the receiving plate 31 is provided with a collection groove 312; the end of the scraper 331 is in contact with the surface of the collection groove 312; the conveying pipe 311 is disposed in the collection groove 312; the conveying pipe 311 is connected to the collection unit 5.

[0039] In this embodiment, the collection unit 5 is a collection tank, which facilitates the transportation and treatment of residual liquid by the staff. The residual liquid on the filling unit 2 drips into the collection tank 312, and the scraper 331 scrapes off the surface of the collection tank 312, so that the residual liquid enters the collection unit 5 through the conveying pipe 311.

[0040] Preferably, the frame 1 is provided with a sliding plate 11; the sliding plate 11 is provided with a sliding groove 12 for the receiving plate 31 to slide; the sliding groove 12 is provided with a limiting boss 13; the receiving plate 31 is provided with a limiting groove 313; the limiting boss 13 and the limiting groove 313 cooperate to prevent the receiving plate 31 from disengaging from the sliding plate 11.

[0041] In this embodiment, the connecting rod 32 pushes the receiving plate 31 to slide on the sliding groove 12, thereby allowing the receiving plate 31 to move closer to or further away from the filling unit 2. Secondly, by setting the limiting boss 13 and the limiting groove 313, the receiving plate 31 will not detach from the sliding plate 11 when the connecting plate pushes the Garioban to move, thus achieving stable movement of the receiving plate 31 on the sliding plate 11.

[0042] Preferably, the filling unit 2 includes a filling head 21 and a moving frame 22 connected to an external feeding mechanism; the filling head 21 is connected to the moving frame 22; the moving frame 22 is connected to the power output end of the lifting unit 4; the moving frame 22 is slidably connected to the frame 1; and the moving frame 22 is hinged to one end of the connecting rod 32.

[0043] In this embodiment, the external feeding mechanism delivers the liquid to be filled into the bottle through the filling head 21. The two ends of the connecting rod 32 are hinged to the moving frame 22 and the receiving plate 31, respectively. The lifting unit 4 drives the moving frame 22 to move, thereby driving the receiving plate 31 to move closer to or away from the filling unit 2 through the connecting rod 32.

[0044] Preferably, the lifting unit 4 is a cylinder, a hydraulic cylinder, or a lead screw motor.

[0045] In this embodiment, the lifting unit 4 is preferably a cylinder, but other power sources are not excluded.

[0046] Preferably, the scraper 331 is a scraper 331 made of resin or rubber.

[0047] In this embodiment, the scraper 331 is made of resin to avoid friction between the scraper 331 and the receiving plate 31, which would cause wear to the receiving plate 31 and improve the service life of the receiving plate 31.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
