Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically a quantitative feeding machine. Background Technology

[0002] The screw feeder weighs the material passing through a weighing bridge to determine the weight of the material on the conveyor belt. A digital speed sensor at the tail continuously measures the feeder's operating speed. The pulse output of this speed sensor is proportional to the feeder's speed. The speed and weight signals are sent together to the feeder controller, where a microprocessor processes the data to generate and display the cumulative / instantaneous flow rate. This flow rate is compared with the set flow rate, and the control instrument outputs a signal to control the frequency converter, changing the feeder's drive speed to adjust the material flow rate, bringing it closer to and maintaining the set feed flow rate, thus achieving the required quantitative feeding.

[0003] Among them, Chinese patent with announcement number CN215206913U discloses a quantitative feeder, which can not only control the output amount through a drive motor, but also the spiral disc outside the rotating column can play a stirring role during the feeding process. An auxiliary rotation device is installed inside the box. The main advantage is that during the process of the spiral disc pushing the material, the feeding ring inside the auxiliary rotation device will rotate with the spiral disc, and the internal rotating block can help the discharge port to discharge the material, preventing a large amount of material from accumulating at the discharge port.

[0004] While the above solutions use an auxiliary rotating device to assist in discharging material from the outlet and prevent material accumulation, the quantitative feeder achieves quantitative feeding by rotating the auger. Powdered and lumpy materials are prone to blockage due to agglomeration before entering the feeding box from the hopper, affecting the amount of material entering the feeding box and consequently the quantitative feeding accuracy of the feeder. Therefore, we provide a quantitative feeding machine to solve these problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: a quantitative feeding machine, including a support structure, a feeding tank 3, a screw feeding assembly, a swing rod 10, a reciprocating swing assembly, and a drive assembly.

[0030] The support structure includes a base plate 1 and an upright plate 2, with the bottom end of the upright plate 2 fixedly connected to the base plate 1.

[0031] The feeding tank 3 is fixedly connected to the vertical plate 2. The side of the feeding tank 3 away from the vertical plate 2 is the discharge port. The feeding tank 3 is fixedly connected to the hopper 7. The bottom plate 1, the vertical plate 2 and the feeding tank 3 form an "up" structure. The bottom plate 1 and the vertical plate 2 support the feeding tank 3. The hopper 7 has a structure that is wide at the top and narrow at the bottom, which facilitates the flow of materials into the feeding tank 3.

[0032] The screw feeding assembly is installed inside the feeding tank 3 and is used to horizontally and quantitatively convey the material entering the feeding tank 3 from the hopper 7 to the discharge port. The screw feeding assembly includes a bearing seat 5 embedded in the feeding tank 3. An auger shaft 4 is rotatably connected to the bearing seat 5. The feeding end of the auger shaft 4 is located inside the feeding tank 3, and the other end of the auger shaft 4 is located outside the feeding tank 3. After the auger shaft 4 rotates, it can convey the material from the connection between the feeding tank 3 and the hopper 7 to the discharge port of the feeding tank 3.

[0033] A support seat 6 is rotatably connected to the bearing seat 5, and the bottom end of the support seat 6 is fixedly connected to the base plate 1. The bearing seat 5 and the support seat 6 are used to provide auxiliary support for the feeding tank 3 to ensure the stability of the feeding tank 3.

[0034] The swing rod 10 is installed inside the hopper 7, and the swing rod 10 is fixedly connected with the dispersing rods 11 arranged at equal intervals.

[0035] The reciprocating swing assembly is mounted on the vertical plate 2 and is used to reciprocate the dispersing rod 11 on the swing rod 10 to crush the material in the hopper 7. The reciprocating swing assembly includes a synchronous shaft 9 rotatably connected to the vertical plate 2. One end of the synchronous shaft 9 is fixedly connected to the swing rod 10, and the other end of the synchronous shaft 9 is fixedly connected to the linkage rod 12. The synchronous shaft 9 is located above the bearing seat 5.

[0036] The linkage rod 12 drives the swing rod 10 to move synchronously through the synchronous shaft 9. When the linkage rod 12 moves in an arc reciprocating motion at the end away from the synchronous shaft 9, it will also move the swing rod 10 in an arc reciprocating motion. This allows the swing rod 10 to stir and crush the material in the hopper 7 through the dispersing rod 11, thus preventing the material from blocking at the connection between the feeding tank 3 and the hopper 7.

[0037] The reciprocating swing assembly also includes a support shaft 14 rotatably connected to the upright plate 2. A disc 15 is fixedly connected to the support shaft 14, and a round shaft 16 is fixedly connected to the disc 15. A groove 13 is provided on the linkage rod 12, and the round shaft 16 is located in the groove 13. When the disc 15 rotates, the round shaft 16 moves in the groove 13 to squeeze the linkage rod 12, thereby providing the linkage rod 12 with arc-shaped reciprocating power.

[0038] The drive assembly is mounted on the base plate 1 and is used to provide a power source for the screw feeding assembly and the reciprocating swing assembly simultaneously. The drive assembly includes a motor 8 mounted on the base plate 1. The output shaft of the motor 8 is equipped with a first pulley 17 and a second pulley 18. A third pulley 19 is mounted on the auger shaft 4 and is connected to the first pulley 17 in a transmission connection. A fourth pulley 20 is mounted on the support shaft 14 and is connected to the second pulley 18 in a transmission connection.

[0039] After the motor 8 is started, the output shaft can drive the auger shaft 4 to rotate through the third pulley 19 and the first pulley 17 to achieve the effect of quantitative screw feeding. It can also drive the support shaft 14 to rotate through the fourth pulley 20 and the second pulley 18 to provide power for the linkage rod 12 to move in an arc.
