Description

Technical Field

[0001] This utility model relates to oil filling equipment, and in particular to a servo filling component. Background Technology

[0002] The oil filling valve is a core component of the oil filling production line. Its main function is to precisely control the start and stop of oil filling (such as edible oil, lubricating oil, fuel oil, etc.), regulate the flow rate, and ensure quantitative accuracy, directly determining filling efficiency and product quality. The discharge valve of the filling assembly controls the release of oil, and this location is prone to oil dripping.

[0003] The existing oil filling valve uses an upward lifting mechanism. After a period of use, the extension and retraction accuracy of the cylinder will decrease. Due to the lack of a tight seal, oil will slowly seep out of the valve outlet, forming droplets that will eventually drip down. In addition, there is a connection between the existing lifting valve plug's lever lifting mechanism and the oil flow channel. During frequent lifting and lowering of the lever, contaminants that affect the oil quality may be introduced.

[0004] Therefore, it is necessary to develop a servo filling component that overcomes the low precision of the cylinder and the separation structure between the lifting mechanism and the oil flow channel. Utility Model Content

Detailed Implementation

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figure 1 As shown, a servo filling assembly includes an oil container 100, a lifting valve core assembly 200, and an oil outlet 300.

[0035] The lifting valve core assembly 200 includes an upper mounting base 210, a connecting rod 220, a lower mounting base 230, a lead screw lifting wheel 240, a servo motor 250, a lifting lead screw 260, and a valve core 270.

[0036] The lower mounting base 230 is fixedly installed on the top of the oil container 100. The lower mounting base 230 and the upper mounting base 210 are fixedly assembled through a connecting rod 220. The screw lifting wheel 240 is horizontally rotatably installed on the upper mounting base 210. The lifting screw 260 is vertically arranged and threadedly assembled with the screw lifting wheel 240.

[0037] The lifting screw 260 is fixedly mounted with a sliding plate 261, which slides along the connecting rod 220 in a vertical direction; the oil outlet 300 is installed at the bottom of the oil container 100, which corresponds to the upper screw lifting wheel 240; the valve core 270 is located inside the oil outlet 300; the top of the valve core 270 is provided with a pull rod 280, and the upper end of the pull rod 280 is fixedly mounted to the lower end of the lifting screw 260;

[0038] The oil container 100 is provided with a pull rod passage. A flexible shielding membrane 290 is provided between the body of the pull rod 280 and the pull rod passage. The inner ring of the flexible shielding membrane 290 is fixedly installed on the body of the pull rod 280, and the outer ring of the flexible shielding membrane 290 is fixedly installed on the oil container 100.

[0039] The servo motor 250 is mounted on the upper mounting base 210, and the servo motor 250 forms a transmission assembly with the lead screw lifting wheel 240 via a transmission belt.

[0040] The lifting valve core assembly 200 of the solution uses a screw lifting principle. The screw is controlled by the rotation of the screw to drive the valve core to rise and fall, thereby opening and closing the oil outlet 300. The solution uses a servo motor 250 for screw drive. By utilizing the precise control characteristics of the servo motor 250, as well as the accuracy and reliability of screw lifting, the opening control accuracy of the valve core 270 and the sealing reliability under long-term use are improved. In addition, the device also sets a flexible shielding membrane 290 between the pull rod and the oil container 100.

[0041] like Figure 2 As shown, it also includes a weighing component 400, which includes a horizontally arranged support base 410 and a weighing sensor 420.

[0042] The load cell 420 is fixedly installed on the support base 410, and the oil container 100 is fixedly installed on the load cell 420.

[0043] The weighing component 400 is used to quantify the oil in the oil container 100. By weighing, the weight of the filled oil is controllable, ensuring the consistency of the filling effect.

[0044] A vertical support plate 430 is fixedly installed at one end of the support base 410 facing away from the oil outlet 300;

[0045] A container filling valve 500 is fixedly installed on the upper end of the vertical support plate 430, and an oil inlet cylinder 110 is installed on the oil container 100 corresponding to the position of the container filling valve 500.

[0046] The outer side of the oil outlet of the container filling valve 500 is provided with a trumpet-shaped cover ring 510. The lower end of the cover ring and the lower end of the oil outlet of the container filling valve 500 form an annular sleeve. The upper end of the oil inlet cylinder 110 is correspondingly accommodated in the annular sleeve structure. The oil inlet cylinder 110 and the oil outlet 300 of the container filling valve 500 do not contact each other.

[0047] The solution uses a vertical support plate 430 to support the container filling valve 500. Then, a horn-shaped cover ring 510 is set at the oil outlet 300 of the container filling valve 500. By using a non-contact filling method and setting a dustproof structure at the non-contact pipeline position, the filling structure is prevented from interfering with the oil container 100, so that the oil container 100 is independently installed on the weighing component 400.

[0048] like Figure 1 and Figure 2 As shown, it also includes a centering device 600, which includes an open cylinder. The two working ends of the open cylinder are respectively equipped with centering plates. The openings of the centering plates are "V" shaped and the openings of the two centering plates are arranged opposite to each other.

[0049] The centering device 600 is used to position the container to be filled so that the filling port of the container corresponds to the oil outlet 300.

[0050] Figure 1 The system also includes an oil receiving device 700, which includes an oil receiving box and a guide channel;

[0051] The oil receiving box is fixedly installed at one end of the guide channel, and the oil receiving box is connected to the guide channel.

[0052] The guide channel is fixedly installed on the inner working end of the open cylinder. When the open cylinder is in the open state, the oil receiving box is located directly below the oil outlet 300. When the open cylinder is in the retracted state, the oil receiving box moves synchronously to one side of the oil outlet 300 along with the working end of the cylinder.

[0053] When the centering device 600 is in the open state, there is an oil receiving box below the oil outlet 300 to prevent falling oil droplets; when the centering device 600 is in the clamped state, the oil receiving box moves to one side, and there is an oil drum below the oil outlet 300 waiting for filling; by setting up the oil receiving box, oil droplets are further prevented from falling onto the filling conveyor line.

[0054] Figure 1 and Figure 3 The system also includes an oil return assembly, which includes a piston extraction device 800 and an oil return cylinder 810.

[0055] The bottom of the valve core 270 is a tapered structure with the tip pointing downwards. The lowest position of the bottom of the valve core 270 is provided with an oil collection channel 820, which extends upwards to the upper part of the pull rod.

[0056] The oil return assembly is fixedly installed on the upper mounting base 210. The oil return cylinder 810 drives the piston extraction device 800 to retract and extend. The air chamber of the piston extraction device 800 is connected to the oil collection channel 820 on the upper part of the pull rod through a pipeline.

[0057] The oil return assembly uses the piston extraction device 800 to collect the oil droplets gathered at the center of the valve core 270 into the oil collection channel 820. During filling, the oil in the oil collection channel 820 is pushed out and drawn back at the location where the oil is gathered, thereby preventing the oil droplets from falling.

[0058] In addition, a tensioning wheel is included, which is mounted on the upper mounting base 210;

[0059] The tensioning pulley is located on the outside of the drive belt.

[0060] Improve the reliability of drive belt installation.

[0061] In addition, the flexible shielding film 290 is made of either plastic or rubber.

[0062] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
