Description

Technical Field

[0001] This utility model relates to the field of plastic testing technology, and in particular to a plastic product testing device. Background Technology

[0002] In modern industrial production and daily life, plastic products, with their significant advantages of being lightweight, corrosion-resistant, low-cost, and easy to process, have been widely penetrated into many fields such as packaging, electronics, automobiles, medical, and construction. From films and containers for food packaging to housing components for electronic devices and plastic structural parts in automobiles, the quality of plastic products is directly related to product performance, safety, and even consumer health. Various quality problems can occur in the production, transportation, and storage of plastic products. Plastic product testing devices are systems that integrate multiple testing technologies and equipment to automatically or semi-automatically test the appearance, dimensions, performance, and composition of plastic products. Their core function is to ensure that plastic products meet quality standards, safety regulations, and usage requirements, thereby reducing the influx of substandard products into the market.

[0003] Inspectors visually inspect product surfaces for defects and use calipers and micrometers for dimensional measurements. However, the results are heavily influenced by the inspectors' experience, fatigue, and subjective judgment, making accuracy and consistency difficult to guarantee, resulting in high rates of missed and false detections. Existing equipment replaces manual visual inspection with a fully automated process, fundamentally solving the problems of low efficiency and high subjectivity associated with manual inspection. By integrating high-resolution industrial cameras, high-speed image acquisition cards, and precision transmission systems, the equipment can continuously inspect dozens to hundreds of products per minute. However, plastic products inspected at high speeds are not pressure-resistant enough for user use, and broken fragments can cause injury, failing to meet user needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plastic product testing device, which aims to improve the problem of plastic products being not pressure resistant in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic product testing device, comprising a sloped annular disc, a base plate fixedly connected to the middle of the sloped annular disc, a cleaning mechanism fixedly connected to the top of the base plate, a pressure mechanism fixedly connected to the middle of the top of the base plate, the pressure mechanism being used to test the pressure resistance of the plastic product, the cleaning mechanism comprising a motor, the bottom of the motor fixedly connected to the front side of the top of the base plate, a transmission assembly fixedly connected to the output end of the motor, a reciprocating lead screw fixedly connected to the rear side of the transmission assembly, a sliding plate threadedly connected to the outer wall of the reciprocating lead screw, a brush fixedly connected to the bottom of the sliding plate, and a sliding assembly provided on the left side of the sliding plate.

[0006] As a further description of the above technical solution:

Guide components are fixedly connected to the top corners of the base plate. A top plate is fixedly connected to the top of the guide components. A pushing component is fixedly connected to the center of the top plate. A moving plate is fixedly connected to the bottom of the outer wall of the pushing component. A pressure measuring column is fixedly connected to the center of the bottom of the moving plate. A protective component is fixedly connected to the outer wall of the slope annular disc.

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

[0009] The transmission assembly includes a first bevel gear, the middle of which is fixedly connected to the output end of the motor, and a second bevel gear meshing with the outer wall of the first bevel gear.

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

[0011] The reciprocating lead screw is rotatably connected to fixed columns on both the front and rear sides of its outer wall, and a foot support is fixedly connected to the bottom corner of the base plate.

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

[0013] The sliding assembly includes a slide rod, the outer wall of which is fixedly connected to the rear side of the fixed column, and a circular hole is provided on the left side of the sliding plate.

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

[0015] The guide assembly includes a guide post, the bottom of which is fixedly connected to the top of the base plate, and a sliding ring is slidably connected to the outer wall of the guide post.

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

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

[0019] The protective assembly includes a protective shell, the middle of which is fixedly connected to the outer wall of the base plate, and the bottom front and rear sides of the protective shell are provided with arc-shaped openings.

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

[0021] 1. In this utility model, the linkage structure of the bevel gear driven by the motor and the reciprocating screw drives the sliding plate to move stably along the sliding rod, so that the bottom brush automatically cleans the table surface. Dust and plastic debris can be directly discharged from the device through the arc-shaped opening, reducing the user's operating burden, making equipment maintenance more time-saving and labor-saving, and significantly improving the ease of use.

[0022] 2. In this utility model, during the pressure test of plastic products, when the cylinder pushes the pressure measuring column, the moving plate slides along the guide column to ensure accurate pressure application. At the same time, the protective shell can effectively shield the plastic products from the fragments generated by the pressure bursting, avoiding accidental injury to the user. This not only ensures the accuracy of the pressure test, but also eliminates potential safety hazards through the protective mechanism, making the test operation safer and more reliable.

[0039] Working principle: By controlling the motor 201, the bevel gear 2021 at the output end drives the reciprocating screw 203 to rotate, and the sliding plate 204 on the outer wall moves back and forth. The left side slides on the slide rod 2061 to ensure stable translation, so that the brush 205 fixed at the bottom of the sliding plate 204 sweeps the table surface, allowing dust and plastic debris to enter the arc-shaped opening 3072 and be discharged from the device, eliminating the need for manual cleaning and making it convenient for users to operate.

[0040] By placing the plastic product on top of the placement plate 301, the control cylinder 3051 causes the push rod 3052 at the bottom to push the pressure measuring column 306, thus conducting a pressure test on the plastic product at the bottom. The moving plate 303 on the outer wall slides at the guide column 3021 at the corner, ensuring that the pressure measuring column 306 at the bottom accurately presses down on the plastic product at the bottom. When the plastic product cannot withstand the pressure, the fragments will burst open and will be blocked by the protective shell 3071, preventing injury to the user.
