Technical Field

[0001] The utility model relates to the technical field of suction machine feeding, in particular to a suction machine feeding device for injection molding production. Background Art

[0002] Suction machines are widely used in the raw material conveying industry for injection molding machines, extruders and other equipment. Suction machines are often used to suck out materials and transfer them to injection molding machines during workshop production. The existing suction machine silos are mostly exposed environments. When workers add raw materials, dust splashes and flies everywhere in the workshop, which not only puts operators in a harsh working environment and has adverse effects on their health, but also pollutes the surrounding environment. Due to the different particle sizes, components and densities of powder dry mixes, powder bridging often occurs during the feeding process, or a small amount of powder agglomerates, resulting in poor feeding of dry mixes, making injection molding production prone to abnormal situations such as product shortages or unstable production processes. In addition, injection molding machines require multiple mixed feeding processes during the injection molding process.

[0003] For this reason, we propose a suction feeding device for injection molding production to solve the above problems. Utility Model Content

[0022] The two ends of the round rod 105 are rotatably sleeved with one end of the two first fixed blocks 101 away from the inner wall of the feeding tank 1. The round rod 105 is located between the two first fixed blocks 101 and is fixedly sleeved with the middle part of the two second connecting blocks 104. One side wall of the second connecting block 104 is fixedly connected to a side wall of the feeding plate 106. The retraction of the cylinder 1031 drives the piston rod 1032 to retract, and the retraction of the piston rod 1032 drives the first connecting block 1033 to move. The displacement of the first connecting block 1033 drives the round rod 105 to flip ninety degrees. The flipping of the round rod 105 drives the two second connecting blocks 104 to flip, and the feeding plate 106 follows its flipping. At this time, the surface of the feeding plate 106 is horizontally parallel to the inner wall of the feeding tank 1 and is ninety degrees perpendicular to the inner top wall of the feeding tank 1.

[0023] Reference Figure 1-6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. Specifically, the top wall of the feeding tank 1 is fixedly connected with the tops of two second fixing blocks 102, and a side wall of a clip 1021 is fixedly connected across the bottom of the second fixing block 102, and the clip 1021 can clamp one end of the material bag.

[0024] One end of a suction pipe 3 of a suction machine is fixedly connected to the bottom end of the feeding tank 1 , and one end of a motor 2 is fixedly installed at the center of the bottom of the feeding tank 1 .

[0025] The bottom of the stirring shaft 201 is fixedly connected to the rotating shaft of the motor 2, and the stirring shaft 201 is fixedly sleeved with a ribbon stirrer 202. When the motor 2 is started, the rotating shaft rotates to drive the stirring shaft 201 to rotate, and the ribbon stirrer 202 rotates with it. The ribbon stirrer 202 can better mix the materials evenly.

[0026] The feeding tank 1 is provided with a feeding port 109 , one end of which is located at the upper end of the first fixing block 101 and the other end of which is located at the top wall of the feeding tank 1 .

[0028] Reference Figure 1-6 , which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, the gull-wing door 107 is opened, the bagged material is sealed and placed on the material holding plate 106, two clips 1021 are used to clamp the unsealed end of the bag, and the gull-wing door 107 is closed. At this time, the feeding tank 1 is closed, and the start cylinder 1031 is retracted to drive the piston rod 1032 to retract. The retraction of the piston rod 1032 drives the first connecting block 1033 to move. The displacement of the first connecting block 1033 drives the round rod 105 to flip 90 degrees. The flipping of the round rod 105 drives the two second connecting blocks 104 to flip, and the material holding plate 106 flips with it. At this time, the surface of the material holding plate 106 is horizontally parallel to the inner side wall of the feeding tank 1 and perpendicular to the inner top wall of the feeding tank 1 at 90 degrees. Further, the bagged material is not supported by the material holding plate 106, and the unsealed end is clamped by the clip 10 21 is clamped, and the bagged material begins to release the material under the action of gravity. To avoid incomplete release, when the cylinder 1031 is started, the cylinder 1031 extends to drive the piston rod 1032 to extend, and the piston rod 1032 extends to drive the first connecting block 1033 to move, and the displacement of the first connecting block 1033 drives the round rod 105 to flip 90 degrees. The flipping of the round rod 105 drives the two second connecting blocks 104 to flip, and the material holding plate 106 follows its flipping. At this time, the surface of the material holding plate 106 is horizontally parallel to the top wall of the feeding tank 1. Repeat the above steps, the material is fed, and the motor 2 is started. The motor 2 starts the motor shaft to rotate and drive the stirring shaft 201 to rotate, and the spiral ribbon agitator 202 rotates with it. The spiral ribbon agitator 202 can better evenly mix the material and pre-mix the material. Finally, the suction pipe 3 of the suction machine sucks the material out.
