[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-7As shown, a method for using a multi-material filling and metering device includes a multi-material filling and metering device, which includes a frame component 1, at least two groups of servo metering components 2, and at least two groups of volume adjustment components 3 compatible with the servo metering components 2; the frame component 1 includes a base plate 101, and a front vertical plate 102 and a rear vertical plate 103 arranged in front and rear are provided above the base plate 101; the servo metering component 2 includes a screw assembly 20 and a slider assembly 22; the screw assembly 20 includes a screw 2001 and a nut 2010 compatible with the screw 2001, the screw 2001 is arranged between the front vertical plate 102 and the rear vertical plate 103, and the rear part of the screw 2001 is connected to a servo drive connecting shaft 2002; the slider assembly 22 includes a slider 2201, and the middle part of the slider 2201 is provided with a slider fixing sleeve hole 2202 compatible with the nut 2010, and the slider 2201 The front part is connected with two piston rods 2203 arranged in parallel, and the front vertical plate 102 is provided with a through hole for passing the piston rod 2203; the volume adjustment component 3 includes two material cylinders 301 arranged in parallel, and a piston 302 connected with the piston rod 2203 is provided in the material cylinder 301, and the rear part of the material cylinder 301 is fixed to the front vertical plate 102 through a volume adjustment flange, and the front part of the material cylinder 301 is provided with a suction and discharge connector 304 for connecting the material bin rotary valve; during use, the servo drive connecting shaft 2002 is connected to the servo motor and drives the lead screw 2001 to rotate, and the lead screw 2001 drives the nut 2010 to move forward and backward, so that the nut 2010 drives the slider 2201 to move forward and backward, and 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 sucking the material. This method has accurate filling and is easy to use. Through the cooperation of the frame component 1, the servo metering component 2 and the volume adjustment component 3, a single filling machine can be filled with multiple materials at the same time, which greatly reduces the equipment procurement cost, equipment floor space and labor cost; and it has a multi-range metering adjustment function, which can be driven by the servo system and cooperate with the replacement of the material cylinder 301 with different diameters to achieve range adjustment, thereby achieving high-precision filling or stuffing.

[0036] In order to conveniently realize the filling amount or filling amount of two or more materials, the cylinders 301 in at least two groups of volume adjustment components 3 absorb different materials respectively, and the diameters of the cylinders 301 in at least two groups of volume adjustment components 3 are different, that is, the cylinders 301 in the volume adjustment components 3 driven by the same group of servo metering components 2 absorb the same material, and the diameters of the two cylinders 301 in this group are the same, while the cylinders 301 in the volume adjustment components 3 driven by another group of servo metering components 2 absorb different materials, and the diameter of the cylinders 301 in this group is different from the diameter of the cylinders 301 in the previous group. And because there are two cylinders in one group of volume adjustment components, the diameter of the cylinder is determined by the maximum filling range and accuracy requirements. When the filling amount is small, the method of reducing the cylinder diameter is often adopted to improve the filling accuracy.

[0037] The material cylinder 301 is connected to the rotary valve below the material bin through 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 end of the material cylinder, the upper part of the rotary valve is connected to the material bin, and the front end of the rotary valve is connected to the filling head or the stuffing injection head. When the piston moves backward under the drive of the piston rod 2203, the material cylinder 301 can absorb the material in the material bin 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 the stuffing injection head connected to the rotary valve in turn for filling.

In order to further ensure the stable movement of the slider 2201, one of the two guide rods 2101 is arranged at the lower left side of the lead screw 2001, and the other is arranged at the upper right side of the lead screw 2001. A first guide rod fixing hole 2104 is provided on the front vertical plate 102, and the front part of the guide rod 2101 is fixed in the first guide rod fixing hole 2104, and a second guide rod fixing hole 2103 is provided on the rear vertical plate 103, and the rear part of the guide rod 2101 is fixed in the second guide rod fixing hole 2103, so as to facilitate the fixing of the guide rod 2101.

[0039] The screw assembly 20 also includes a first bearing seat 2003 and a second bearing seat 2004. The front vertical plate 102 is provided with a first bearing seat sleeve hole compatible with the first bearing seat 2003, and the rear vertical plate 103 is provided with a second bearing seat sleeve hole 2009 compatible with the second bearing seat 2004; a first bearing mounting position 2005 is provided at the front of the screw 2001 near the first bearing seat, and a first bearing 2008 is provided on the outer sleeve of the first bearing mounting position 2005; a second bearing mounting position 2006 is provided at the rear of the screw 2001 near the second bearing seat 2004, and a second bearing is provided on the outer sleeve of the second bearing mounting position 2006, so as to facilitate the servo drive connecting shaft 2002 to drive the screw 2001 to rotate. In order to facilitate the installation and fixation of the first bearing 2008 and the second bearing, the outer diameters of the first bearing installation position 2005 and the second bearing installation position 2006 are both smaller than the outer diameter of the middle part of the screw 2001. At the same time, the first bearing installation position 2005 is also sleeved with a first plane bearing 2007, and the first plane bearing 2007 is arranged in front of the first bearing 2008; the second bearing installation position 2006 is also sleeved with a second plane bearing, and the second bearing is arranged in front of the second plane bearing. Therefore, through the arrangement of the first plane bearing 2007 and the second plane bearing, there is no movement of the wire and the rod back and forth, which further ensures the metering accuracy and smooth rotation of the screw 2001.

[0040] In order to facilitate the connection of the servo motor, the servo drive connecting shaft 2002 extends backward from the second bearing seat hole 2009. The servo drive connecting shaft 2002 and the lead screw 2001 adopt an integrated structure to ensure the connection strength of the servo drive connecting shaft 2002 and the lead screw 2001.

[0041] A piston rod fixing hole 2204 is provided on the slider 2201, 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 with a piston rod buckle 2205, and a slot matched with the piston rod buckle 2205 is provided on the piston 302, thereby realizing a buckle connection between the piston rod 2203 and the piston 302, which can facilitate the installation of cylinders 301 of different calibers and realize range adjustment, and can also facilitate the replacement and cleaning of components such as the piston 302 and the cylinder 301.

[0042] The volume adjustment flange 303 is provided with a plurality of annular step grooves, and the plurality of annular step grooves are distributed on the front side of the volume adjustment flange 303 in a concentric circle structure, so that the annular step grooves of different diameters can be adapted to the material cylinder 301 of different diameters, thereby playing the role of volume replacement, so that the metering device can be easily replaced with different measuring ranges.

[0043] Two groups of servo metering components 2 arranged in parallel are arranged on the frame component 1, and the front sides of the two groups of servo metering components 2 are provided with volume adjustment components 3 adapted to the servo metering components 2, so as to facilitate the filling or stuffing of multiple materials.

[0044] The method for using the multi-material filling and metering device provided by the present invention has the following beneficial effects:

[0045] (1) One machine is suitable for filling or stuffing of multiple materials. One servo system controls two material cylinders to realize "one-to-two" filling or stuffing, that is, it can measure the same material to realize single material filling and stuffing, and it can also measure different materials to realize multi-material filling and stuffing;

[0046] (2) It has a multi-range metering adjustment function. The range adjustment is achieved by replacing cylinders of different diameters. The servo system drives the piston to achieve high-precision metering. It can not only achieve high-precision filling or stuffing, but also control different filling or stuffing amounts of different materials;

[0047] (3) Existing methods for filling or injecting multiple materials require multiple devices and multiple operators. Using this device to achieve filling or injecting multiple materials only requires one device and one operator, which greatly reduces the equipment procurement cost and labor cost, and greatly reduces the equipment footprint.
