Description

Technical Field

[0001] The utility model relates to the technical field of aluminum composite plate production, in particular to a blanking device for aluminum composite plate extrusion production. Background Art

[0002] In the production process of aluminum composite panels, materials need to be unloaded through a silo, and the raw materials need to be extruded using an extrusion roller installed below the silo to obtain aluminum composite panel blanks, and the aluminum composite panel blanks need to be dried and cooled to form aluminum composite panels.

[0003] In order to avoid the condensation of raw materials in the silo, the utility model patent with application number 201620317330.8 discloses an extrusion device for producing aluminum composite panels. A pushing mechanism pushes a vibrating rod to move in the silo to prevent the raw materials from solidifying in the silo and promote the discharge of bubbles in the raw materials. A vibrating mechanism is also installed on the periphery of the silo to prevent the raw materials from adhering to the inner wall of the silo. However, the structure is relatively complex, which increases noise and cost, and needs to be improved. Utility Model Content

[0004] The utility model aims to provide a feeding device for extrusion production of aluminum composite plates, which can feed raw materials by vibration and avoid the problems of solidification and adhesion to the inner wall of the silo.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A feeding device for extrusion production of aluminum composite plates comprises: a silo, a rotating shaft, an eccentric block and a stirring rod, wherein the rotating shaft is rotatably arranged in the silo and extends horizontally along the length direction of the silo, the eccentric block is eccentrically arranged on the rotating shaft, the stirring rod is arranged at intervals on one side or both sides of the eccentric block, and a feeding port is arranged at the bottom of the silo directly below the rotating shaft, and the feeding port is a rectangular structure.

[0007] Wherein, the number of the eccentric blocks is at least 2, and they are distributed on the rotating shaft at intervals.

[0008] Among them, a motor for driving the rotating shaft to rotate is arranged at one end of the silo, and a bearing seat corresponding to the rotating shaft is arranged at the other end of the silo.

[0009] Wherein, the cross section of the silo is a V-shaped structure.

[0010] Wherein, the bottom of the silo is vertically provided with material guide plates located on both sides of the discharge port.

[0011] Wherein, the guide plates on both sides of the feed opening are parallel to each other.

[0012] The beneficial effects of the utility model are as follows: a feeding device for extrusion production of aluminum composite plates drives multiple eccentric blocks to rotate in a silo through a rotating shaft, and utilizes the exciting force of the rotation of the eccentric blocks to induce vibration of the raw materials in the silo, thereby avoiding the problem of raw material solidification and adhesion to the inner wall of the silo, ensuring the smoothness of feeding, and driving the stirring rod to stir the raw materials, promoting the discharge of bubbles in the raw materials, achieving two goals at one stroke, without the need to install a vibration mechanism outside the silo, thereby reducing the vibration and noise problems of the silo.

[0014] Figure 2 yes Figure 1 Left view of . DETAILED DESCRIPTION

[0015] Combine the following Figure 1~Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The feeding device for extrusion production of aluminum composite panels shown in the figure comprises: a silo 1, a rotating shaft 2, an eccentric block 3 and a stirring rod 4. The rotating shaft 2 is rotatably arranged in the silo 1 and extends horizontally along the length direction of the silo 1. In this embodiment, a motor 5 for driving the rotating shaft 2 to rotate is arranged at one end of the silo 1. The motor 5 is connected to the front end of the rotating shaft 2, and the high-speed rotation of the rotating shaft 2 is driven by the motor 5.

[0017] In addition, a bearing seat 6 corresponding to the rotating shaft 2 is provided at the other end of the silo 1, and the rear end of the rotating shaft 2 is supported by the bearing in the bearing seat 6 to improve the stability of rotation.

[0018] The eccentric block 3 is eccentrically arranged on the rotating shaft 2, such as Figure 1 As shown, the eccentric block 3 has a thin structure and a small deadweight, which reduces the driving force requirement for the rotating shaft 2. The rotating shaft 2 drives the rotation of multiple eccentric blocks 3 in the silo 1, and the exciting force of the rotation of the eccentric blocks 3 is used to induce the vibration of the raw materials in the silo 1, thereby avoiding the problem of the raw materials solidifying and adhering to the inner wall of the silo 1, ensuring the stability of material discharge, and reducing the maintenance frequency of the inner wall of the silo 1.

[0019] In this embodiment, the number of the eccentric blocks 3 is at least 2, and they are spaced apart on the rotating shaft 2, forming a plurality of exciting force generating points in the silo 1, and performing multi-point vibration excitation of the raw materials in the silo 1, thereby ensuring the effect of slight high-frequency vibration of the raw materials, avoiding the problem of vibration dead corners, and alleviating the problem of raw materials adhering to the inner wall of the silo 1. Therefore, there is no need to install other vibration mechanisms outside the silo 1, thereby reducing the vibration and noise problems of the silo 1.

[0020] like Figure 2As shown, the bottom of the silo 1 is provided with a discharge port 8 located directly below the rotating shaft 2. In this embodiment, the cross-section of the silo 1 is a V-shaped structure, and the discharge port 8 is a rectangular structure, so that the raw materials in the silo 1 enter the discharge port 8 in an orderly manner under the action of gravity, which is beneficial to the subsequent extrusion forming of the aluminum composite plate by the extrusion roller.

[0021] The stirring rods 4 are arranged at intervals on one side or both sides of the eccentric block 3. When the eccentric block 3 rotates, the stirring rods 4 are driven to stir the raw materials in the silo 1, thereby improving the turning effect of the raw materials and promoting the discharge of bubbles in the raw materials.

[0022] Guide plates 7 are vertically arranged at the bottom of the silo 1 on both sides of the discharge port 8. In this embodiment, the guide plates 7 on both sides of the discharge port 8 are parallel to each other, which can maintain the width of the discharge port 8 and strengthen the discharge guidance.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
