Description

Technical Field

[0001] This utility model relates to the technical field of plastic clarity measuring equipment, specifically a test device for measuring the clarity of plastics. Background Technology

[0002] When measuring the sharpness of plastic samples, light emitted from a light source typically enters an entrance slit, is converged into parallel rays by a collimating lens, and then shines onto the sample. The light is reflected or transmitted through the sample surface to form an image, which is then focused onto a moving grating by the collimating lens. The light passing through the moving grating is received by a photodetector, and the received composite signal is processed to obtain the sharpness value of the sample.

[0003] However, existing testing devices for measuring the sharpness of plastics typically use fixed installations, making adjustment difficult. This necessitates repeatedly disassembling and reassembling the plastic to adjust its position when measuring sharpness values ​​at different locations, which is time-consuming, labor-intensive, and reduces measurement efficiency. To address these issues, we propose a new testing device for measuring the sharpness of plastics. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for measuring the clarity of plastics, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for measuring the clarity of plastics, comprising:

[0006] A base is provided, on which a light source is fixedly mounted. An entrance slit plate is also fixedly mounted on the base, positioned to one side of the light source. A collimating lens is fixedly mounted on the top wall of the base on the side of the entrance slit plate. An adjustment mechanism is located in the middle of the top wall of the base. A decollimating lens is fixedly mounted on the top wall of the base on the side of the adjustment mechanism. A movable grating is mounted on the top wall of the base on the side of the decollimating lens. A light receiver is mounted on the top wall of the base on the side of the grating. The adjustment mechanism includes a first adjustment seat, which is fixedly welded to the top wall of the base. A screw is rotatably mounted in the inner cavity of the first adjustment seat. A movable seat is threadedly connected to the screw. The movable seat is slidably connected to the inner cavity of the first adjustment seat. A connecting seat is fixedly welded to the top wall of the movable seat. A support plate is fixedly welded to the top of the connecting seat. A second adjustment seat is fixedly welded to the top wall of the front end of the support plate. A fixing rod is fixedly welded to the inner cavity of the second adjustment seat. A slider is slidably connected to the fixing rod. A clamping mechanism is provided on the slider.

[0007] Preferably, the clamping mechanism includes two fixed seats, both of which are fixedly welded to the rear side wall of the slider. A first stud is threadedly connected to one of the fixed seats. A pressure plate is rotatably mounted on one end of the first stud. Two guide posts are fixedly welded to the pressure plate, and the guide posts are slidably connected to the corresponding fixed seats.

[0008] Preferably, an L-shaped bracket is fixedly welded to one side wall of the slider, and a second stud is threaded onto the L-shaped bracket, with a locking plate fixedly installed at the end of the second stud.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, this utility model features a clamping mechanism for holding and fixing flat plastic. During the inspection of the flat plastic, rotating the screw allows the moving seat to move back and forth on the first adjusting seat. The moving seat, through components such as the support plate and the second adjusting seat, can drive the clamped flat plastic to move back and forth, thus adjusting its position in the front-back direction. A slider can slide up and down on the second adjusting seat, moving the clamped flat plastic up and down, thus adjusting its position in the vertical direction. Tightening the second stud in the forward direction causes the locking plate to press against the outer wall of the second adjusting seat, thereby limiting and fixing the slider after adjustment. This design facilitates the adjustment of the flat plastic's position, eliminating the need for repeated disassembly and reassembly, and improving work efficiency. Attached Figure Description
