Embodiment 1

[0028] Such as Figures 1 to 3 As shown, a hopper device for a springless microcomputer combination scale includes a hopper body 1, a hopper door 2, a motor 3, a swing rod 4, a movable bracket 5, and a mounting frame 6, and the swing rod 4 is connected to the motor 3 The output end of the motor 3 is mounted on the mounting frame 6, the movable bracket 5 is connected to the mounting frame 6, the hopper body 1 is mounted on the mounting frame 6, and the hopper door 2 is connected to the mounting frame 6. The hopper body 1 is connected, and it is characterized in that it also includes a door drive shaft 7 and a pull rod 8, the hopper door 2 is connected with the movable bracket 5 through a pull rod 8, and the bucket door drive shaft 7 is installed on the movable bracket 5 , the swing link 4 is movably connected with the bucket door drive shaft 7 . The bucket door driving shaft 7 includes a driving frame 701 and a rotating shaft 702 fixed at both ends of the driving frame 701. A ...

Embodiment 2

[0038] This springless microcomputer combined scale hopper device is the same as the embodiment except the following technical features. The self-locking part is a baffle, the baffle is located at the lower end of the first side plate, and the baffle and the first side plate are perpendicular to each other. That is, the self-locking rod in Embodiment 1 is replaced with a baffle plate, and other structures remain unchanged. The baffle plate and the first side plate 502 are perpendicular to each other and integrally formed with the first side plate 502 to simplify production and installation steps. Simultaneously, the structure of the device is simpler. When the motor control pendulum 4 moves to the bottom, the hopper door 2 is closed, and now the baffle plate withstands the mounting bracket 6, realizing the self-locking with the same effect as in embodiment 1, ensuring that the hopper door is closed.

Abstract

The invention discloses a hopper device for a spring-free microcomputer combined scale, which comprises a hopper body, a hopper door, a motor, a swing rod, a movable support and a mounting rack, wherein the swing rod is connected to an output shaft of the motor, the motor is mounted on the mounting rack, the movable support is hinged with the mounting rack, the hopper body is mounted on the mounting rack, and the hopper door is hinged with the hopper body; a hopper door driving shaft and a pull rod are further included, the hopper door is connected with the movable support through the pull rod, the hopper door driving shaft is installed on the movable support, and the swing rod is movably connected with the hopper door driving shaft. A spring does not need to be used, the motor is used for driving the swing rod to rotate, rotation of the swing rod is converted into movement of the hopper door driving shaft through the movable mechanism, opening and closing of the hopper door are controlled through the pull rod, and high noise caused by springback of the spring, and falling precision affected by generated vibration are reduced; and the conditions of spring breakage and falling are avoided.

Description

technical field [0001] The invention belongs to the technical field of combined scale equipment, and in particular relates to a hopper device for a springless microcomputer combined scale. Background technique [0002] The hopper is an important part of the combination scale, which is widely used in the field of mechanical packaging. The current hopper device mainly consists of a hopper body, a hopper door, a motor and a frame structure. The upper end of the hopper door is hinged to the hopper body, the motor is installed on the frame, and the power output shaft of the motor is connected to the hopper door, and the hopper door is connected to the frame structure through a return spring. Although the hopper device with this structure can realize the basic functions, it has the following defects: after the motor drives the hopper door to open, the closing of the hopper door requires the restoring force of the return spring to reset, which causes a large impact between the hop...
