Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule compression testing technology, specifically to a plastic granule compression testing device. Background Technology
[0002] Plastic granules, as a basic raw material for the production of plastic products, are widely used in various industries such as packaging, automobile manufacturing, electronics, and construction due to their lightweight, corrosion resistance, and high plasticity. In these fields, plastic products need to withstand varying degrees of pressure; therefore, the compressive strength of plastic granules directly affects the quality and service life of the final product.
[0003] Plastic granules need to undergo compression testing during processing. Existing compression testing equipment does not have protective functions during use. During loading and unloading, the operator's arm is located at the bottom of the pressure plate. If the equipment malfunctions, the downward pressure can easily injure the operator's arm, which is unacceptable. Therefore, we propose a plastic granule compression testing device. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a plastic pellet compression testing device that is easy to use and solves the problem that existing compression testing devices lack protective functions during use. During the loading and unloading process, the operator's arm is located at the bottom of the pressure plate, and if the equipment malfunctions, the downward pressure can easily cause injury to the operator's arm, thus failing to meet the usage requirements.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic granule compression resistance testing device, comprising a workbench, a fixed base fixedly connected to the central axis at the bottom of the workbench, a dual-axis motor fixedly connected to one side of the fixed base, a drive shaft fixedly connected to the output end of the dual-axis motor, rotating shafts provided on both sides of the top of the workbench at the central axis, a connecting rod fixedly connected to one side of the rotating shaft, a connecting pin fixedly connected to one side of the connecting rod, a fixed rod movably connected to the surface of the connecting pin, a bracket fixedly connected to one side of the fixed rod, an adjusting rod fixedly connected to the other side of the rotating shaft, a fixed pin fixedly connected to one side of the adjusting rod, a vertical rod movably connected to the surface of the fixed pin, a shelf fixedly connected to one side of the vertical rod, an electric telescopic rod fixedly connected to the central axis at the top of the bracket, a pressure sensor fixedly connected to the bottom of the electric telescopic rod, and a pressure plate fixedly connected to the bottom of the pressure sensor.

[0008] Preferably, a vertical plate is movably connected to one side of the rotating shaft surface via a bearing, and the bottom of the vertical plate is fixedly connected to the worktable.

[0010] Preferably, a sliding rod is fixedly connected to the left side of the front of the rectangular plate, and the surface of the sliding rod is slidably connected to the threaded sleeve.
[0011] Compared with the prior art, this utility model provides a plastic pellet compression resistance testing device, which has the following beneficial effects:
[0012] 1. When this utility model is in operation, the pressure value is set through the external PLC controller, and the electric telescopic rod is started. The electric telescopic rod drives the pressure sensor to move, and the pressure sensor drives the pressure plate to move. The pressure plate squeezes the material. After the pressure sensor detects that the pressure value is the same as the set value, the pressure plate can be returned to its original position. Then, the dual-axis motor is started, which drives the drive shaft to rotate, thereby driving the rotating shaft to rotate. The rotating shaft drives the connecting rod and the adjusting rod to rotate. The connecting rod drives the connecting pin to rotate, and the connecting pin drives the fixed rod to move. The fixed rod drives the bracket to move backward, thereby causing the pressure plate to move backward. The adjusting rod drives the fixed pin to rotate, and the fixed pin drives the vertical rod to move. The vertical rod drives the placement plate to move forward. Then, it is possible to observe whether the material is damaged and to replace the material.
[0013] 2. After changing the material, the top of the shelf can be manually cleaned. At the same time, the drive motor can be started, which drives the lead screw to rotate. The lead screw drives the threaded sleeve to move, the threaded sleeve drives the connecting frame to move, and the connecting frame drives the scraper to move. The scraper cleans the bottom of the pressure plate, so that the residual material falls into the inner cavity of the frame for easy collection. Attached Figure Description
