Description

An intelligent equipment for rubber cutting and grinding

technical field

The invention relates to the technical field of processing rubber test parts, in particular to an intelligent equipment for rubber cutting and polishing.

Background technique

Some existing rubber flaking equipment and rubber grinding equipment are two independent equipment, which need to be installed and used separately and operated at multiple stations, which brings a lot of inconvenience. The existing technology belongs to the traditional mechanical process. The traditional rubber planer and rubber grinding machine have low work efficiency and have hidden dangers to the health of the test personnel. At the same time, the accuracy of the equipment is poor, and it is not suitable for the processing of rubber test parts. The thickness of the shavings is controlled by adjusting the left and right thickness screws when the traditional rubber flaking machine is shaving. This method is used to control the thickness of the rubber shavings, which requires a high level of experience for the test personnel. The thickness deviation on both sides is large, the thickness is difficult to control, the uniformity cannot be controlled, and the planing error is large. The technology of adjusting the thickness of the planed rubber sheet through the screw is in urgent need of improvement. When the traditional rubber grinding machine is grinding, the motor speed is constant. If the rubber strip is polished for a long time at high speed and the temperature is too high, the rubber strip will be extended, and the extension of the rubber strip will affect the accuracy of the test. During the rubber grinding process, the test personnel need to operate the equipment all the way. While grinding the rubber, the rubber will emit irritating and toxic gases, which poses hidden dangers to the health of the test personnel. The large size deviation of the unevenness of the rubber sheet will prolong the grinding time. The whole process of grinding requires personnel to control the equipment throughout the process. When the new equipment is grinding, it does not require personnel to control the equipment throughout the process.

The cutting knife is fixed by the adjusting bolt, and the height of the cutting knife can be adjusted by moving the increase or decrease washer, thereby adjusting the thickness of the rubber to be cut.

Technical effect and advantage of the present invention:

1. The traditional rubber planing and grinding equipment manually rotates the screw rods at both ends to adjust the height of the pressing sheet, which leads to the height deviation at both ends due to human operation, which makes the rubber sheet produce unevenness at both ends during planing. In the uniform state, the planing effect is poor and the size deviation is large. This patent uses a stepping motor, which is driven by a set of precision ball screws to provide high-precision positioning information, and automatically adjusts the height by inputting the required tablet height. The two groups of rollers are driven by gears to ensure that the speed of the two groups of rollers is consistent, so as to avoid the phenomenon of rolling up or down the rubber sheet. The reduction motor provides power to achieve smooth shaving. It solves the problem that the experience requirements of the test personnel are high when rubber planing is performed. When rubber planing is insufficient, the thickness deviation of the left and right sides of the planed rubber sheet is relatively large, the thickness is difficult to control, the uniformity cannot be controlled, and the planing error is large. During the cutting process, it is easy to cause the inclined knife to pull the material and deform the cut part of the rubber sheet, resulting in uneven cutting section of the rubber sheet.

2. Rubber grinding equipment. When traditionally grinding rubber, the operator turns the hand wheel, and the hand wheel rotates in the opposite direction of the grinding wheel. The speed of turning the hand wheel is to control the speed of rubber grinding. Manually controlling the speed of the hand wheel will cause the speed of rubber grinding. Unevenness affects sanding quality. When grinding different rubber materials, the corresponding grinding speed can be matched according to the material so as not to affect the grinding quality of rubber products. The improvement plan of this research is to place the rubber sheet on the hollow pressing roller, and use the built-in pressing mechanism on the hollow pressing roller and the two sets of pressing mechanisms below to compress the rubber sheet. The sheet roller provides rotational power in the opposite direction to the grinding wheel to achieve uniform grinding. After improvement, it can be freely set according to different rubber materials to match the corresponding grinding speed. Traditionally, this process requires the operator to control the speed of rubber grinding throughout the whole process. After improvement, only the operator needs to set the parameters.

3. The thickness of rubber grinding is set by shaking the handle, so that the upper carriage is fed forward along the lower rail. There is a dial on the handle. Turning the dial is to control the thickness and precision of rubber grinding. After the improvement, in the feeding movement of the hollow tablet roller, a closed-loop stepping motor is used to cooperate with a group of precision ball screws for feeding, which can effectively achieve the precision of the last two digits of the millimeter level, which fully complies with the "Rubber Physical Test Method for Sample Preparation and Regulatory General Procedures" standard. After technical improvement, under the requirements of technical specifications, the standard of precision control of grinding materials has also been improved.

4. The traditional slicing equipment can only slice a fixed thickness. The slicing equipment in this research can slice a variety of thicknesses. According to the samples of different thicknesses required in the standard, the slicing blade gasket is provided to adjust the slicing thickness. Realize the slicing thickness required by experimental groups with different needs.

5. When the rubber sheet is traditionally polished, the rubber will emit irritating and toxic gases, which poses hidden dangers to the health of the test personnel. After improving the technology, a vacuum cleaner is installed under the grinding wheel, which can effectively absorb the dust during rubber grinding. For the rest of the dust caused by the rotation of the hollow pressing roller and the grinding wheel, a set of acrylic covers are set up to prevent the rubber irritating gas from polluting the laboratory environment.
