[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0032] The embodiment of the utility model provides a material supply device, which controls the material output of each piston assembly by controlling the piston of the piston assembly that receives each material, thereby controlling the proportion of each material, thereby solving the technical problem that the injection molding device in the prior art is difficult to meet the feeding requirements of materials with different proportions.

[0033] like Figure 1-2 As shown, the material supply device provided by the embodiment of the utility model includes a batching output unit 10 and a discharge drive unit 20, the batching output unit 10 includes a plurality of first piston assemblies 11 and a plurality of second piston assemblies 12, each first piston assembly 11 and each second piston assembly 12 is used to alternately receive materials; the discharge drive unit 20 is connected to the pistons of each first piston assembly 11 and each second piston assembly 12, and is used to drive the piston to slide when each first piston assembly 11 receives material so that each second piston assembly 12 outputs material, or drive the piston to slide when each second piston assembly 12 receives material so that each first piston assembly 11 outputs material.

[0034] Specifically, by setting a batching output unit 10 and a discharging drive unit 20, the batching output unit 10 includes a plurality of first piston assemblies 11 and a plurality of second piston assemblies 12. When materials are mixed, different types of materials are transported to each first piston assembly 11 or each second piston assembly 12, and are alternately received by the first piston assembly 11 and each second piston assembly 12. The discharging drive unit 20 is connected to the pistons of each first piston assembly 11 and each second piston assembly 12, and the discharging drive unit 20 can realize the output of each material in each first piston assembly 11 and each second piston assembly 12 only by controlling the sliding of the piston;

[0035] When each first piston assembly 11 receives one group of materials to be mixed, the discharging drive unit 20 outputs each material to be mixed in each second piston assembly 12 by driving the piston of the second piston assembly 12. After the second piston assembly 12 outputs each type of material, it receives the next group of materials. When each second piston assembly 12 receives materials, the discharging drive unit 20 outputs each type of different materials received by each first piston assembly 11 by driving the piston of each first piston assembly 11, and then realizes uninterrupted output of materials through the alternating output of the discharging drive unit 20. During the material output process, the discharging drive unit 20 only needs to control the sliding distance of the piston to control the amount of material output by each first piston assembly 11 and each second piston assembly 12, so that the output of materials in any proportion can be realized to meet the feeding requirements of materials in different proportions.

[0036] It can be understood that the material supply device of this embodiment mainly mixes various materials in a certain proportion and then supplies them into the injection molding device for injection molding. It can also be used in any environment where various materials need to be mixed and transported in a certain proportion.

[0037] In this embodiment, Figure 1-2 As shown, the first piston assemblies 11 and the second piston assemblies 12 are arranged alternately.

[0038] In this embodiment, Figure 1As shown, each first piston assembly 11 and each second piston assembly 12 includes a cylinder and a piston, the piston is slidably connected to the inside of the cylinder, and is enclosed with the inner wall of the cylinder to form a piston cavity, the cylinder is provided with a feed port and a discharge port, the cylinders of each first piston assembly 11 and each second piston assembly 12 are the same size, the feed port and the discharge port are connected to the piston cavity, when the first piston assembly 11 and each second piston assembly 12 receive materials, the discharge drive unit 20 drives the piston to slide a certain distance according to the required amount of material, so as to increase the piston cavity, so that a certain amount of material enters the piston cavity through the feed port, when the first piston assembly 11 and each second piston assembly 12 output materials, the discharge drive unit 20 drives the piston to squeeze the piston cavity, and outputs the material from the piston cavity through the discharge port, thereby finally realizing the output of the material.

[0039] In this embodiment, the number of the first piston assembly 11 and the second piston assembly 12 can be adaptively set according to the type and quantity of materials to be mixed, that is, when two materials need to be mixed, the number of the first piston assembly 11 and the second piston assembly 12 are both 2, and when three materials need to be mixed, the number of the first piston assembly 11 and the second piston assembly 12 are both 3.

[0040] In this embodiment, for ease of understanding, taking the two glues A and B to be mixed as an example, when mixing the two glues A and B, the two glues A and B are first respectively conveyed to one group of the first piston assembly 11 and the second piston assembly 12. At this time, the other group of the first piston assembly 11 and the second piston assembly 12 respectively output the internal glue A and glue B in a certain proportion through the discharge drive unit 20. After the output is completed, the group of the first piston assembly 11 and the second piston assembly 12 receives the additional glue A and glue B, while the other group of the first piston assembly 11 and the second piston assembly 12 outputs the previously received glue A and glue B in a certain proportion, thereby achieving uninterrupted output of glue A and glue B under the continuous alternating output of the two groups of the first piston assembly 11 and the second piston assembly 12.

[0041] It can be understood that the discharging drive unit 20 can be a drive device connected to two adjacent first piston assemblies 11 and second piston assemblies 12, and can synchronously control the pistons of the two adjacent first piston assemblies 11 and second piston assemblies 12 at the same time.

[0042] In one embodiment, Figure 1-2As shown, the discharging drive unit 20 includes a plurality of drivers 21, each of which is connected to the piston of each first piston assembly 11 and each second piston assembly 12, and is used to drive the piston to slide. Specifically, the driver 21 can individually control the pistons of each first piston assembly 11 and each second piston assembly 12, thereby being able to accurately control the amount received and output by each first piston assembly 11 and each second piston assembly 12.

[0043] It can be understood that the driver 21 can be any driving device that can drive the piston to slide, such as a servo motor, a servo cylinder or a hydraulic cylinder.

[0044] In the present embodiment, taking the case where the number of the first piston assemblies 11 and the number of the second piston assemblies 12 are both two and the driver 21 is a servo motor, in order to realize the control of the piston sliding amount, it is only necessary to control the pulse signal of the servo motor, that is, when the pulse signals of the servo motors of each first piston assembly 11 or each second piston assembly 12 are the same, each first piston assembly 11 or each second piston assembly 12 will output materials in equal proportions; if one servo motor connected to the first piston assembly 11 or each second piston assembly 12 uses 100 pulse signals and the other servo motor uses 120 pulse signals, the piston sliding ratio of each first piston assembly 11 or each second piston assembly 12 will be 1:1.2, so that the material ratio output by the piston of the first piston assembly 11 or each second piston assembly 12 is 1:1.2.

[0045] In one embodiment, Figure 1 As shown, the material supply device further includes a material storage unit 30 and a pumping unit 40. The material storage unit 30 is used to store various materials to be mixed. One end of the pumping unit 40 is connected to the material storage unit 30, and the other end of the pumping unit 40 is connected to each first piston assembly 11 and each second piston assembly 12, and is used to alternately transport the material in the material storage unit 30 to each first piston assembly 11 and each second piston assembly 12. Specifically, the material storage unit 30 can be used to store various materials to be mixed, and the pumping unit 40 can alternately transport the materials stored in the material storage unit 30 to each first piston assembly 11 and each second piston assembly 12, thereby realizing the alternate transportation of the materials to each first piston assembly 11 and each second piston assembly 12.

Each pump body 42 and each first valve body 43 are installed on the feed distribution module 41. The pump body 42 is used to transport various types of materials in the material storage unit 30 to each first piston assembly 11 and each second piston assembly 12 through the feed distribution module 41. Each first valve body 43 is used to control the on-off of the feed distribution module 41 and each first piston assembly 11 and each second piston assembly 12.

When the pump body 42 is started, each material can be conveyed to each second piston assembly 12 respectively, thereby realizing the alternating conveyance of each material to each first piston assembly 11 and each second piston assembly 12.

[0049] It can be understood that the feed distribution module 41 can be a plurality of parallelly arranged pipeline structures with one end connected to each storage box 31 and the other end connected to each first piston assembly 11 and each second piston assembly 12.

After the material is transported to the inside of the connecting block, it will be distributed to each feed distribution channel, and can finally be transported to each first piston assembly 11 or each second piston assembly 12 through the feed distribution channel.

[0052] In one embodiment, Figure 1 As shown, the feed pipe group 411 includes a feed main pipe and two feed branches, the feed main pipe is connected to the material storage unit 30, one end of the two feed branches is connected to the feed main pipe, and the other ends of the two feed branches are respectively connected to one of the adjacent first piston assemblies 11 and the second piston assemblies 12, each pump body 42 is respectively installed on the feed main pipe, and each first valve body 43 is respectively installed on each feed branch pipe. Specifically, when the material is transported to the first piston assembly 11, the first valve body 43 on the feed branch pipe connected to the first piston assembly 11 is opened, and the material enters the feed main pipe through the drive of the pump body 42, and then passes into the first piston assembly 11 through the feed branch pipe; when the material is transported to the second piston assembly 12, the first valve body 43 on the feed branch pipe connected to the second piston assembly 12 is opened, and the material enters the feed main pipe through the drive of the pump body 42, and then passes into the second piston assembly 12 through the feed branch pipe.

One end of the discharge distribution module 51 is connected to each first piston assembly 11 and each second piston assembly 12, and is used to output the materials discharged from each first piston assembly 11 and each second piston assembly 12. The mixer 52 is connected to the other end of the discharge distribution module 51, and is used to gather the materials output by the discharge distribution module 51. Specifically, the materials discharged from the first piston assembly 11 or each second piston assembly 12 will be transported to the mixer 52 via the discharge distribution module 51, mixed at the mixer 52, and finally used for injection molding by the injection molding device.

[0055] It can be understood that the discharge receiving pipe group 512 can be a plurality of discharge pipes connected to the gathering pipe 511 at one end and connected to each first piston assembly 11 and each second piston assembly 12 at the other end.

[0057] In one embodiment, Figure 1 As shown, the mixing unit 50 further includes a plurality of second valve bodies 53, each of which is respectively installed on each discharge branch pipe. Specifically, when the material of the first piston assembly 11 is discharged, the second valve body 53 on the discharge branch pipe connected to the first piston assembly 11 is opened, and the second valve body 53 on the discharge branch pipe connected to the second piston assembly 12 is closed, so that the material can only be discharged from the discharge branch pipe connected to the first piston assembly 11, and will not enter the second piston assembly 12 from the discharge branch pipe connected to the second piston assembly 12; when the material of the second piston assembly 12 is discharged, the second valve body 53 on the discharge branch pipe connected to the second piston assembly 12 is opened, and the second valve body 53 on the discharge branch pipe connected to the first piston assembly 11 is closed, so that the material can only be discharged from the discharge branch pipe connected to the second piston assembly 12, and will not enter the first piston assembly 11 from the discharge branch pipe connected to the first piston assembly 11, which facilitates the discharge of the material, and further facilitates the discharge of the material.

[0061] The specific working principle of the material supply device provided by the utility model is as follows: before supplying glue A and glue B, glue A and glue B are stored in respective storage boxes 31, and when supplying glue A and glue B, the first valve body 43 connected to the two first piston assemblies 11 is opened, the second valve body 53 connected to the two first piston assemblies 11 is closed, and each pump body 42 is started, so that glue A and glue B enter the two first piston assemblies 11 respectively, and at the same time, the two driving members connected to the pistons of the two first piston assemblies 11 drive the pistons of the two first piston assemblies 11 to move, and the piston chamber is adaptively increased according to the input amount of glue A and glue B. After the two first piston assemblies 11 respectively complete the input of a certain amount of glue A and glue B, the second valve body 53 connected to the first piston assemblies 11 is opened, and the second valve body 53 connected to the two second piston assemblies 12 is closed, and the driving member drives the pistons of the two first piston assemblies 11 to compress the piston chamber, and glue A and glue B are squeezed out of the two first piston assemblies 11 respectively, and the glue A and glue B squeezed out of the two first piston assemblies 11 are mixed in the mixer 52;

[0062] During the process of the two first piston assemblies 11 outputting materials, the first valve body 43 connected to the two first piston assemblies 11 is closed, and the second valve body 53 connected to the two first piston assemblies 11 is opened, so that the A glue and the B glue enter the two second piston assemblies 12 respectively. At the same time, the two driving members connected to the pistons of the two second piston assemblies 12 drive the pistons of the two second piston assemblies 12 to move, and the piston chamber is adaptively increased according to the input amount of the A glue and the B glue.

The driving member drives the pistons of the two second piston assemblies 12 to compress the piston chamber, and the A glue and the B glue are squeezed out of the two second piston assemblies 12 respectively, and the A glue and the B glue squeezed out of the two second piston assemblies 12 are mixed in the mixer 52;

[0063] By alternately inputting and outputting materials by the first piston assembly 11 and the second piston assembly 12, the mixing efficiency of glue A and glue B can be effectively improved, and by controlling the pistons of the first piston assembly 11 and the second piston assembly 12 by each driving member, the mixing ratio of glue A and glue B can be adjusted as needed to meet the mixing requirements of different ratios of glue A and glue B.
