[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1-7As shown, a multi-material filling and metering device includes a filling and metering device body, which includes a frame component 1, at least two sets of servo metering components 2, and at least two sets of volume adjustment components 3 adapted to the servo metering components 2. The frame component 1 includes a base plate 101, with a front upright plate 102 and a rear upright plate 103 arranged in a front-rear configuration above the base plate 101. The servo metering components 2 include a lead screw assembly 20 and a slider assembly 22. The lead screw assembly 20 includes a lead screw 2001 and a lead nut 2010 adapted to the lead screw 2001. The lead screw 2001 is disposed between the front upright plate 102 and the rear upright plate 103, and a servo motor is connected to the rear of the lead screw 2001. The drive connecting shaft 2002; the slider assembly 22 includes a slider 2201, the middle of which is provided with a slider fixing sleeve hole 2202 adapted to the nut 2010, the front of the slider 2201 is connected to two piston rods 2203 arranged in parallel, and the front upright plate 102 is provided with a through hole for the piston rods 2203 to pass through; the volume adjustment component 3 includes two material cylinders 301 arranged in parallel, the material cylinders 301 are provided with pistons 302 connected to the piston rods 2203, the rear of the material cylinders 301 is fixed to the front upright plate 102 by a volume adjustment flange, and the front of the material cylinders 301 is provided with a suction and discharge connector 304 for connecting to the material silo rotary valve. This design offers precise filling and ease of use. Through the coordinated operation of the frame component 1, servo metering component 2, and volume adjustment component 3, it enables simultaneous filling of multiple materials using a single filling machine, significantly reducing equipment procurement costs, floor space requirements, and labor costs. Furthermore, it features multi-range metering adjustment capabilities, which can be achieved through servo system drive and by replacing material cylinders 301 with different diameters, thus enabling high-precision filling or injection.

[0034] The servo metering component 2 also includes a guide rod assembly 21, which includes two guide rods 2101. The two guide rods 2101 are respectively disposed on both sides of the lead screw 2001, and the slider 2201 has a guide rod sleeve hole 2102. A bushing adapted to the guide rod 2101 is disposed within the guide rod sleeve hole 2012, thereby guiding the forward and backward displacement of the slider 2201 with the help of the guide rods 2101. To further ensure the stable movement of the slider 2201, one of the two guide rods 2101 is disposed on the lower left side of the lead screw 2001, and the other is disposed on the upper right side of the lead screw 2001. The front upright plate 102 has a first guide rod fixing hole 2104, and the front part of the guide rod 2101 is fixed in the first guide rod fixing hole 2104. The rear upright plate 103 has a second guide rod fixing hole 2103, and the rear part of the guide rod 2101 is fixed in the second guide rod fixing hole 2103, thereby facilitating the fixing of the guide rods 2101.

[0035] The lead screw assembly 20 also includes a first bearing housing 2003 and a second bearing housing 2004. The front upright plate 102 is provided with a first bearing housing sleeve hole adapted to the first bearing housing 2003, and the rear upright plate 103 is provided with a second bearing housing sleeve hole 2009 adapted to the second bearing housing 2004. The lead screw 2001 near the first bearing housing is provided with a first bearing mounting position 2005 at the front, and a first bearing 2008 is sleeved on the first bearing mounting position 2005. The lead screw 2001 near the second bearing housing 2004 is provided with a second bearing mounting position 2006 at the rear, and a second bearing is sleeved on the second bearing mounting position 2006, thereby facilitating the servo drive connecting shaft 2002 to drive the lead screw 2001 to rotate. To facilitate the installation and fixation of the first bearing 2008 and the second bearing, the outer diameters of both the first bearing mounting position 2005 and the second bearing mounting position 2006 are smaller than the outer diameter of the middle part of the lead screw 2001. At the same time, a first flat bearing 2007 is also sleeved on the outside of the first bearing mounting position 2005, and the first flat bearing 2007 is located in front of the first bearing 2008; a second flat bearing is also sleeved on the outside of the second bearing mounting position 2006, and the second bearing is located in front of the second flat bearing. Thus, through the arrangement of the first flat bearing 2007 and the second flat bearing, there is no back-and-forth movement of the lead screw and rod, further ensuring the measurement accuracy and smooth rotation of the lead screw 2001.

[0036] To facilitate connection to the servo motor, the servo drive connecting shaft 2002 extends rearward from the second bearing housing hole 2009. The servo drive connecting shaft 2002 and the lead screw 2001 adopt an integrated structure to ensure the connection strength between the servo drive connecting shaft 2002 and the lead screw 2001.

[0037] The slider 2201 is provided with a piston rod fixing hole 2204. The rear part of the piston rod 2203 is fixed in the piston rod fixing hole 2204. The front part of the piston rod 2203 is connected to a piston rod buckle 2205. The piston 302 is provided with a groove that matches the piston rod buckle 2205, thereby realizing the buckle connection between the piston rod 2203 and the piston 302. This not only facilitates the installation of material cylinders 301 of different diameters and realizes the range adjustment, but also facilitates the replacement and cleaning of components such as piston 302 and material cylinder 301.

[0038] The volume adjustment flange 303 is provided with several annular stepped grooves, and these annular stepped grooves are distributed in a concentric circle structure on the front side of the volume adjustment flange 303. Thus, the annular stepped grooves of different diameters can be adapted to material cylinders 301 of different diameters, thereby achieving the function of volume change and making it easy to change different measuring ranges of the metering device.

[0039] The frame component 1 is provided with two sets of servo metering components 2 arranged in parallel, and each set of servo metering components 2 is provided with a volume adjustment component 3 adapted to the servo metering component 2 on the front side, so as to facilitate the filling or injection of multiple materials.

[0040] When the filling and metering device is in use, the servo motor is connected to the servo drive connecting shaft 2002 and drives the lead screw 2001 to rotate. The lead screw 2001 drives the lead screw nut 2010 to move forward and backward, so that the lead screw nut 2010 drives the slider 2201 to move forward and backward along the guide rod 2101. The slider 2201 drives the piston in the material cylinder 301 to move through the piston rod 2203, so that the material cylinder 301 performs material filling operation after absorbing material.

[0041] To facilitate the filling or injection of two or more materials, at least two sets of volume adjustment components 3 have their cylinders 301 drawing in different materials, and the cylinders 301 in at least two sets of volume adjustment components 3 have different diameters. Specifically, cylinders 301 in volume adjustment components 3 driven by the same set of servo metering components 2 draw in the same material, and the two cylinders 301 in this set have the same diameter. Conversely, cylinders 301 in volume adjustment components 3 driven by another set of servo metering components 2 draw in different materials, and the diameter of the cylinders 301 in this set is different from that in the previous set. Furthermore, since each set of volume adjustment components has two cylinders, the cylinder diameter is determined by the maximum filling range and accuracy requirements. When the filling volume is small, the cylinder diameter is often reduced to improve filling accuracy.

[0042] The material cylinder 301 is connected to the rotary valve below the material hopper via the suction and discharge connector 304. Each material cylinder 301 has a matching rotary valve. The rear of the rotary valve is connected to the front of the material cylinder, the upper part of the rotary valve is connected to the material hopper, and the front of the rotary valve is connected to the filling head or filling head. When the piston moves backward under the drive of the piston rod 2203, the material cylinder 301 can suck up the material in the material hopper through the rotary valve. When the piston moves forward under the drive of the piston rod 2203, the material in the material cylinder 301 passes through the rotary valve and the filling head or filling head connected to the rotary valve in sequence for filling.

[0043] The multi-material filling and metering device provided by this utility model has the following beneficial effects:

[0044] (1) One machine can adapt to filling or filling of multiple materials. One servo system controls two material cylinders to achieve “one-to-two” filling or filling. That is, it can measure the same material to achieve single material filling and filling, or measure different materials to achieve multi-material filling and filling.

[0045] (2) It has a multi-range metering adjustment function. The range can be adjusted by changing the material cylinder of different diameters. The piston can be driven by the servo system to achieve high-precision metering. It can achieve high-precision filling or filling, and can also control different filling or filling amounts of different materials.

[0046] (3) Other existing methods of filling or injecting multiple materials require multiple machines and multiple operators. Using this device to achieve filling or injecting multiple materials only requires one machine and one operator, which greatly reduces the equipment purchase cost and labor cost, and also greatly reduces the equipment footprint.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
