Description

Technical Field

[0001] This utility model relates to the field of production material feeding technology, and in particular to an automatic feeding device for grinding wheel production. Background Technology

[0002] Grinding wheels are one of the most important types of grinding tools in grinding processes. They are porous bodies made by adding a binder to abrasive materials, pressing them into blanks, drying them, and firing them. They can be used for grinding steels with high hardness, such as high-speed steel, high-carbon steel, and alloy steel. They can also be used for rough grinding, semi-finishing, and finishing grinding of the outer diameter, plane, and various profiles of metal or non-metal workpieces, as well as grooving and cutting. However, in the production process, an automatic feeding device is needed to add raw materials for grinding wheel production. The automatic feeding device for grinding wheel production is based on automated control technology. According to preset programs and parameters, it accurately puts the raw materials required for grinding wheel production into the production equipment. Its purpose is to improve production efficiency, reduce human error, and ensure the accuracy and stability of raw material feeding. First, the feeding parameters of various raw materials are set on the human-machine interface of the control system. When the feeding program is started, the control system will open the valve at the bottom of the corresponding hopper according to the settings. The raw materials are then transported to the mixing machine and other production equipment through the conveying system. However, the conveying method is particularly important during use.

[0003] The existing conveying mechanism mainly consists of a screw shaft, screw blades, a trough, a drive unit, and inlet / outlet sections. The screw shaft is the core component, and the screw blades are welded to the screw shaft and rotate with it. The trough is used to hold the conveyed material. The drive unit is usually a motor and a reducer, used to drive the screw shaft to rotate. The inlet and outlet are located at opposite ends of the trough for material entry and exit. When the screw shaft rotates, the screw blades push the material forward along the trough. Due to the friction between the screw blades and the material, as well as the internal friction of the material itself, the material is conveyed under the push of the screw blades, effectively overcoming the stickiness of the material and conveying it stably. However, this conveying method is prone to clumping and blockage in the conveying pipe when too much raw material is added or the conveying speed is mismatched. In this case, cleaning is required, which affects production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic feeding device for grinding wheel production, which aims to improve the problem in the prior art that when too much raw material is fed and the conveying speed is not matched, it is easy to cause caking and blockage in the conveying pipe, which requires cleaning and affects production efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic feeding device for grinding wheel production, comprising a feeding cylinder, a protective shell fixedly connected to the bottom near the middle of the feeding cylinder, a second motor fixedly connected to the bottom near the middle of the inner wall of the protective shell, a first vibrating gear fixedly connected to the output end of the second motor, multiple second vibrating gears meshing with the outer wall of the first vibrating gear, a first rotating rod fixedly connected to the front side of the inner wall of the second vibrating gear, a second rotating rod fixedly connected to the other end of the first rotating rod, third rotating rods fixedly connected between adjacent second rotating rods, a connecting column rotatably connected to the top of the third rotating rod, a sleeve fixedly connected to the top of the connecting column, a first spring slidably connected to the inner wall of the sleeve, a first connecting rod slidably connected to the inner wall of the first spring, a vibrating plate fixedly connected to the top of the first connecting rod, a fixed block fixedly connected to the lower left end of the feeding cylinder, and a feeding mechanism provided on the inner wall of the feeding cylinder for rotary feeding.

A feeding gear is meshed with the outer wall of the feeding gear. A reverse feeding rod is fixedly connected to the right side of the feeding gear. A forward feeding rod is fixedly connected to the right side of the feeding gear. A feeding port is provided at the top of the feeding cylinder.

[0008] As a further description of the above technical solution:

[0009] A connecting sleeve is fixedly connected to the bottom of the vibrating plate near the middle, and the top of the inner wall of the connecting sleeve is fixedly connected to the top of the connecting rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the protective shell is fixedly connected to the left and right ends of the fixed shell, and the right end of the fixed shell is slidably connected to the outer wall of the rotating rod.

[0012] As a further description of the above technical solution:

[0013] A fixed cylinder is connected to the top left side of the feeding cylinder, and a discharge port is connected to the bottom right end of the feeding cylinder.

[0014] As a further description of the above technical solution:

[0015] A second connecting rod is fixedly connected to the bottom left side of the feeding cylinder, and a base is fixedly connected to the bottom of the second connecting rod.

[0016] As a further description of the above technical solution:

[0017] A connecting bridge is fixedly connected to the bottom right side of the first base, and a second base is fixedly connected to the right side of the connecting bridge. A cylinder is fixedly connected to the top of the second base.

[0018] As a further description of the above technical solution:

[0019] A second spring is fixedly connected to the top of the fixed shell, and a vibration column is fixedly connected to the top of the second spring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the second motor is started, it drives the first and second vibrating gears to rotate. Then, the second vibrating gear drives the second rotating rod to rotate up and down through the first rotating rod. At this time, the second rotating rod moves the third rotating rod up and down, which in turn drives the connecting column to vibrate up and down. Then, the sleeve drives the first spring and the vibrating plate to vibrate up and down. At the same time, the compression of the first spring achieves a buffering effect, so that the blockage in the feeding cylinder is dispersed by the slight vibration. This realizes that when the raw material in the feeding cylinder is blocked, the blockage in the feeding cylinder can be dispersed by slight vibration, so that feeding can continue.

[0022] 2. In this utility model, when feeding is required, the raw material is put into the feeding cylinder through the feeding port, and the motor is started at the same time. At this time, the feeding gear one will rotate, and the feeding gear two will rotate. This will drive the reverse feeding rod to rotate, and at the same time drive the forward feeding rod to rotate. The reverse feeding rod and the forward feeding rod cooperate to push the raw material into the cylinder, realizing the effect of conveying the whole in the feeding cylinder without dead angles.

At the same time, spring 13 is compressed to achieve a buffering effect. At this time, the vibration is transmitted to the feeding cylinder 1, causing the blocked part in the feeding cylinder 1 to disperse due to vibration. This realizes that when the raw material in the feeding cylinder 1 is blocked, the blocked raw material in the feeding cylinder 1 can be dispersed by slight vibration, so that feeding can continue.

[0040] When feeding is required, the raw material is fed into the feeding cylinder 1 through the feeding port 206. At the same time, motor 1 201 is started.
