Stage controllable feeder

Abstract

In the new stage feeder, there is a rotating shaft in the center of the charging container, and a rotating shaft sleeve is installed at its lower end. A horizontal material-shifting rod is welded at the lower end of the sleeve, and a horizontal cross bar is welded a few millimeters upward. There is a horizontal angle θ between the two round bars. A horizontal blanking port loose-leaf baffle is installed on the upper horizontal cross bar. There are blanking holes and loose-leaf components on the circular layer at the small end of the charging container. The shape and size of the loose-leaf piece in the loose-leaf component are the same as the blanking port. The rear edge of the loose-leaf piece has a horizontal axis shaft seat that can be moved together. There is a small boss on the rear part of the upper surface, a loose-leaf horizontal axis gravity hammer, which is perpendicular to the loose-leaf piece, and the loose-leaf piece is embedded in the blanking port. The horizontal material-shifting rod shifts the raw material to the loose-leaf piece, which will press down the small boss on the loose-leaf piece, so that the loose-leaf piece opens downward, and the raw material on it slides into the working container. At the same time, the horizontal cross bar and the loose-leaf baffle of the blanking port just turn to the top of the blanking port to block the raw material from falling. The horizontal material-moving rod continues to rotate in the same direction to release the pressed small boss, and the loose-leaf piece recovers to a horizontal state under the action of the gravity hammer, and is embedded in the blanking opening to close the blanking opening.

Description

Technical Field

[0001] The invention relates to a feeder. Background Art

[0002] There are various feeders on the market, but problems such as uneven feeding and unstable feeding amount exist during use. Summary of the invention

[0003] The object of the present invention is to provide a feeder having the following characteristics:

[0004] 1 The amount of material added each time is roughly the same.

[0005] 2 The time interval between each feeding is the same.

[0006] The object of the present invention is achieved as follows: a rotating shaft is provided at the vertical center of the inverted truncated cone-shaped loading container of the stage controllable feeder, and the rotating shaft is installed in the shaft sleeve on the container cover, and the rotating shaft and the shaft sleeve are movably matched, and can be lifted up and down and rotated in the shaft sleeve. The rotating shaft is driven by the motor on the container cover. The tip of the lower end of the rotating shaft is movably matched with the central circular hole of the circular layer. The upper end of the rotating shaft is equipped with a weight or a movable shaft stopper. A rotating shaft sleeve is installed at the lower part of the rotating shaft. The rotating shaft sleeve rotates with the rotating shaft, and the rotating shaft sleeve contacts the circular layer. Two horizontal round rods are welded at intervals at the lower part of the rotating shaft sleeve, which are the horizontal material-moving rod and the horizontal cross bar. When the rotating shaft rotates to the left, the horizontal cross bar is in front and the horizontal material-moving rod is in the back. The horizontal material-moving rod is welded to the lower end of the rotating shaft sleeve and is flush with the lower end surface. On the longitudinal section of the rotating shaft sleeve, the horizontal cross bar is welded on the horizontal material-moving rod at a distance, and the distance between the two horizontal round rods is determined by the thickness of the raw material. On the cross section of the rotating shaft sleeve, there is a horizontal angle θ between the two horizontal round rods. The horizontal crossbar is equipped with a loose-leaf baffle for the blanking port, which can rotate with the horizontal crossbar as the axis. The area of ​​the loose-leaf baffle for the blanking port is slightly larger than the blanking port, and the rear part of the loose-leaf baffle for the blanking port can be placed on the vertical cylinder on the horizontal feed rod. The horizontal angle θ makes the horizontal distance between the middle parts of the two round rods just equal to the width of the loose-leaf baffle for the blanking port. The seal between the shaft sleeve and the container cover is a mechanical seal.

[0007] The small end of the inverted truncated cone-shaped loading container has a bottom, that is, a circular layer that can be rotated horizontally. The normal working state of the circular layer is horizontal. There is a horizontal axis at both ends of the diameter of the circular layer and on the extension line, which are movably matched with the corresponding holes on the cylindrical wall, and the circular layer can rotate with the horizontal axis as the axis. The rotation of the circular layer is provided with torque by the rocker arm installed on the end of the horizontal axis extending out of the cylindrical wall. There is a fixed seat outside the cylindrical wall. The fixing of the circular layer is completed by the telescopic positioning pin installed on the rocker arm and the positioning hole on the fixed seat through concave-convex matching. The seal between the horizontal axis and the cylinder wall is a mechanical seal.

[0008] There are blanking holes and loose-leaf parts on one side of the circular layer. Two loose-leaf horizontal axis seats are welded to the rear edge of the blanking opening on the bottom surface of the circular layer. A loose-leaf horizontal axis is welded to the rear edge of the loose-leaf piece in the loose-leaf part. The protruding parts on both sides of the loose-leaf horizontal axis are movably matched with the loose-leaf horizontal axis seats. The loose-leaf piece can rotate up and down with the loose-leaf horizontal axis as the axis. The shape and size of the loose-leaf piece in the loose-leaf part are the same as the blanking opening. A gravity hammer is welded below the middle of the loose-leaf horizontal axis, and the gravity hammer is perpendicular to the loose-leaf piece. Under the action of the gravity hammer, the loose-leaf piece remains horizontal and is embedded in the blanking opening. There are two working states: open and closed. There is a small boss in the middle of the rear of the upper surface of the loose-leaf piece.

[0009] The working process of the stage-controlled feeder is as follows: First, the raw materials (including small round sheets) are loaded into the inverted truncated cone-shaped loading container, and the rotating shaft descends to the bottom of the container. Then the rotating shaft starts to rotate, and the rotating shaft sleeve rotates with the rotating shaft, and the horizontal feed lever and horizontal cross bar on the rotating shaft sleeve also start to rotate. The horizontal feed lever on the rotating shaft sleeve rotates on the surface of the circular layer, and the raw materials move with the horizontal feed lever. When the horizontal feed lever rotates to the position close to the blanking port, the raw materials will be pushed onto the loose-leaf sheet by the horizontal feed lever. Since the upper end of the rotating shaft is equipped with a weight or a movable shaft stopper, the horizontal feed lever continues to rotate in the same direction, which will press down the small boss on the loose-leaf sheet, so that the loose-leaf sheet in the blanking port opens downward at a certain angle. Since the loose-leaf sheet tilts downward, the raw materials on the loose-leaf sheet slide into the working container. At the same time, as the horizontal cross bar rotates, the loose-leaf baffle of the blanking port just rotates to the top of the blanking port to block the raw materials from falling. The horizontal material lever continues to rotate in the same direction to release the small boss that is pressed down. The loose-leaf piece returns to a horizontal state under the action of the gravity hammer and is embedded in the blanking port, closing the blanking port. At the same time, as the horizontal crossbar continues to rotate in the same direction, the loose-leaf baffle of the blanking port gradually moves out of the blanking port. The rotating shaft rotates continuously and repeats the above action. From the above process, it can be seen that the raw materials on the loose-leaf piece can only slide down when the rotating shaft rotates one circle. In other words, the amount of material fed each time is roughly the same. Since the rotating shaft speed is constant, the interval time of each feeding is the same. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Attached to the back DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , described is a stage-controllable feeder.

[0025] A rotating shaft (1) is provided at the vertical center of the inverted truncated cone-shaped loading container of the stage-controllable feeder. The rotating shaft (1) is installed in a shaft sleeve on the container cover. The rotating shaft (1) and the shaft sleeve are movably matched and can be lifted up and down and rotated in the shaft sleeve. The rotating shaft (1) is driven by a motor on the container cover. The lower end tip of the rotating shaft (1) is movably matched with the central circular hole of the circular layer (3). A weight or a movable shaft stop is installed at the upper end of the rotating shaft (1). A rotating shaft sleeve (2) is installed at the lower part of the rotating shaft (1). The rotating shaft sleeve (2) rotates with the rotating shaft (1). The rotating shaft sleeve (2) contacts the circular layer (3) and rotates on the surface of the circular layer (3). Two horizontal round bars are welded at intervals at the lower end of the rotating shaft sleeve (2), which are a horizontal cross bar (12) and a horizontal material shifting rod (13). When the rotating shaft (1) rotates to the left, the horizontal cross bar (12) is in front and the horizontal material shifting rod (13) is in the back. The horizontal material shifting rod (13) is welded to the lower end of the rotating shaft sleeve (2) and is flush with the lower end surface. On the longitudinal section of the rotating shaft sleeve (2), the horizontal cross bar (12) is welded on the top of the horizontal material shifting rod (13) at intervals. The upper and lower distances between the two horizontal round bars are determined by the thickness of the raw material block. On the cross section of the rotating shaft sleeve (2), there is a horizontal angle θ between the two horizontal round bars. A blanking opening loose-leaf baffle (11) is installed on the horizontal cross bar (12). The ring at the front edge of the bottom surface of the blanking opening loose-leaf baffle (11) is movably matched with the horizontal cross bar (12). The blanking opening loose-leaf baffle (11) can rotate with the horizontal cross bar (12) as an axis. The area of ​​the blanking opening loose-leaf baffle (11) is slightly larger than the blanking opening (10) on the circular layer (3). The rear side of the blanking opening loose-leaf baffle (11) can be placed on a small vertical cylinder on the horizontal material-moving rod (13). The size of the horizontal angle θ is such that the horizontal distance between the middle parts of the two round rods is exactly equal to the width of the blanking opening loose-leaf baffle (11). The seal between the rotating shaft (1) and the shaft sleeve is a mechanical seal.

[0026] The small end of the inverted truncated cone-shaped loading container has a bottom, i.e., a circular layer sheet (3) that can be rotated horizontally. The circular layer sheet (3) is in a horizontal state in normal working state. There is a horizontal axis at both ends of the diameter and on the extension line of the circular layer sheet (3), which are movably matched with the corresponding holes on the cylindrical wall. The circular layer sheet (3) can rotate with the horizontal axis as the axis. The rotation of the circular layer sheet (3) is provided with torque by a rocker arm installed on the end of the horizontal axis extending out of the cylindrical wall. There is a fixed seat outside the cylindrical wall. The fixing of the circular layer sheet (3) is completed by the telescopic positioning pin installed on the rocker arm and the positioning hole on the fixed seat through concave-convex matching. The seal between the horizontal axis and the cylinder wall is a mechanical seal.

[0027] A blanking hole (10) and a loose-leaf component are provided on one side of the circular layer (3). The rear edge of the blanking hole (10) on the bottom surface of the circular layer (3) is welded with loose-leaf transverse axis seats (8) and (9). A loose-leaf transverse axis (6) is welded below the rear edge of the loose-leaf piece (5) in the loose-leaf component. The protruding parts on both sides of the loose-leaf transverse axis (6) are movably matched with the loose-leaf transverse axis seats (8) and the loose-leaf transverse axis seats (9). The loose-leaf piece (5) in the loose-leaf component can rotate around the loose-leaf transverse axis (6). The loose-leaf piece (5) in the loose-leaf component is installed in the blanking hole (10) on the circular layer (3). The shape and size of the loose-leaf piece (5) in the loose-leaf component are the same as the blanking hole (10). A gravity hammer (7) is welded below the middle of the loose-leaf transverse axis (6), and the gravity hammer (7) is perpendicular to the loose-leaf piece (5). Under the action of the gravity hammer (7), the movable leaf (5) is kept in a horizontal state and embedded in the blanking opening (10). A small protrusion (4) is welded in the middle of the rear part of the upper surface of the movable leaf (5).

[0028] The working process of the stage-controlled feeder is as follows: first, the raw materials (including small round sheet raw materials) are placed in the inverted truncated cone-shaped loading container, the rotating shaft (1) descends to the bottom of the container, the rotating shaft sleeve (2) contacts the round layer sheet (3), and the lower end tip of the rotating shaft (1) is movably matched with the central circular hole of the round layer sheet (3). Then the rotating shaft (1) starts to rotate, the rotating shaft sleeve (2) rotates with the rotating shaft (1), and the horizontal material shifting rod (13) on the rotating shaft sleeve (2) rotates on the surface of the round layer sheet (3). When the horizontal material shifting rod (13) on the rotating shaft sleeve (2) rotates, the raw materials are shifted to move with the horizontal material shifting rod (13). When the horizontal material shifting rod (13) rotates to a position close to the blanking opening (10), the raw material will be pushed onto the loose-leaf piece (5) by the horizontal material shifting rod (13). Since a weight or a movable shaft stopper is installed at the upper end of the rotating shaft (1), the horizontal material shifting rod (13) continues to rotate in the same direction to press down the small boss (4) on the loose-leaf piece (5), so that the loose-leaf piece (5) in the blanking opening (10) opens downward to a certain angle, the loose-leaf piece (5) tilts downward, and the raw material on the loose-leaf piece (5) slides into the working container. At the same time, as the horizontal cross bar (12) rotates, the loose-leaf baffle (11) of the blanking opening just rotates to the top of the blanking opening (10) to block the raw material from falling. The horizontal material shifting rod (13) continues to rotate in the same direction to release the pressed small boss (4), and the loose-leaf piece (5) returns to a horizontal state under the action of the gravity hammer (7), and is embedded in the blanking opening (10), closing the blanking opening (10). At the same time, as the horizontal cross bar (12) continues to rotate in the same direction, the loose-leaf baffle (11) of the material drop opening gradually moves out of the material drop opening (10), and the rotating shaft (1) continues to rotate in the same direction, repeating the above action over and over again. From the above process, it can be seen that the rotating shaft (1) can only slide down the raw materials on the loose-leaf sheet (5) every time it rotates one circle. In other words, the amount of material added each time is roughly the same. Since the rotation speed of the rotating shaft (1) is constant, the interval time of each feeding is the same.
