Description

Technical Field

[0001] The utility model relates to the technical field of kneading machines, in particular to a quantitative feeding device. Background Art

[0002] Kneading machine is a kind of equipment specially used for kneading, mixing, vulcanizing and polymerizing high viscosity and elastic plastic materials. It can be used to produce a variety of products such as silicone rubber, sealant, hot melt adhesive, food glue base, pharmaceutical preparations, etc. The kneading machine uses the strong shear force generated by two Σ blades to quickly mix the materials evenly. It is suitable for processing high-concentration materials to increase the process yield per unit volume. When discharging the materials, the materials conveyed often need to be adjusted manually during transportation, which often leads to errors in manual monitoring of the materials during material transportation. Therefore, a quantitative feeding device is needed.

[0003] The application number retrieved is: CN201710907424.X. A fully automatic filling device for a kneading machine will lift the powder to the workbench, add the material through the feeding port of the feeder, and then continuously feed the powder material into the kneading machine by screw feeding, stirring it evenly while feeding. During the entire feeding process, there is no need to open and close the top cover of the kneading machine. The dust generated during the feeding will be isolated in a space, and the dust generated in the space where the kneading machine body is located is as little as possible. The operation is very convenient and very applicable.

[0004] However, the existing kneading machine still has certain defects in actual use: when conveying materials, since the materials cannot be restricted, when the quantitative conveying of the materials is completed, when the conveying pipeline fails, it often causes deviations in the conveying of the materials. For this reason, we propose a quantitative feeding device. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a quantitative feeding device, which aims to improve the problem that when the material is transported, since the material cannot be restricted, when the quantitative transportation of the material is completed, when the transportation pipeline fails, it will cause the material transportation to deviate.

[0006] The utility model realizes a quantitative feeding device through the following technical scheme, including a kneading machine and a feeding structure, a base is fixed below the kneading machine by bolts, and the feeding structure is arranged above the kneading machine by bolts, and a feeding pipe is arranged above the feeding structure, and the feeding structure includes a feeding box, a control box and a component assembly, and the control box is installed on the four sides of the feeding box by bolts, and the component assembly is installed below the control box by bolts.

[0007] Furthermore, the component assembly includes a rotating ring, a first gear, a second gear, a driving bracket, a blocking plate and a spring, and the first gear is installed at the center of the rotating ring, and the second gear is installed on the outer surface of the first gear, and the driving bracket is installed on the left side of the second gear, and the blocking plate is installed on the side of the driving bracket away from the second gear through bolts, and a spring is provided on the side of the blocking plate away from the first gear.

[0008] Furthermore, a detection bracket is provided on a side of the feeding box away from the control box, a weight sensor is provided below the inner wall of the detection bracket, and a docking tube is provided at the center of the two groups of the detection brackets.

[0009] Furthermore, a rotating shaft is placed at the center of the butt joint, and stirring rods are arranged on both sides of the rotating shaft, and the two groups of stirring rods are staggered with each other.

[0010] Furthermore, the control box includes a connecting bracket, a servo motor and a connecting shaft, and the servo motor is installed on the right side of the connecting bracket, and the connecting shaft is installed at the bottom end of the connecting bracket.

[0011] Furthermore, a mounting bracket is provided at the center of the four groups of feeding pipes, and a driving motor is installed above the mounting bracket by bolts.

[0012] Furthermore, the center of the feeding box is divided into four groups of feeding chambers, and partition plates are provided on both sides of the four groups of feeding chambers.

[0013] The utility model provides a quantitative feeding device, which has the following beneficial effects:

[0014] When the material is transported into the feeding box inside the feeding structure through the feeding pipe, the material is blocked by the blocking plate in the feeding chamber inside the feeding box. At this time, the material squeezes the blocking plate, so that the blocking plate squeezes the detection bracket, so that the blocking plate carries the weight of the material and squeezes the weight sensor, so that the weight sensor obtains the weight of the material. After confirming the weight of the material, the control box controls the component assembly to drive the blocking plate to open and close, thereby completing the material transportation. While the material is being transported, through the blocking plate, when the weight of the material exceeds the limit, the blocking plate can be closed to prevent abnormal materials from falling into the feeding box.

[0024] The component assembly 14 includes a rotating ring 15, a first gear 16, a second gear 17, a driving bracket 18, a blocking plate 20 and a spring 19, and the first gear 16 is installed at the center of the rotating ring 15, and the second gear 17 is installed on the outer surface of the first gear 16, and the driving bracket 18 is installed on the left side of the second gear 17, and the blocking plate 20 is installed on the side of the driving bracket 18 away from the second gear 17 through bolts, and the side of the blocking plate 20 away from the first gear 16 is provided with a spring 19, and at this time when the material is transported into the inside of the feeding box 4, the material falls on the blocking plate 20 and the detection bracket 21, when the weight detection is completed, the control box 5 drives the first gear 16 and the second gear 17 to rotate, and the driving bracket 18 installed by the second gear 17 rotates eccentrically, so that the driving bracket 18 drives the blocking plate 20 to retract inward, thereby bringing the blocking plate 20 away from the detection bracket 21, so that the seal between the blocking plate 20 and the detection bracket 21 exposes the cavity, and the spring 19 is used to limit the blocking plate 20.
