Description

Technical Field

[0001] The present invention relates to the technical field of polyester film testing, and particularly to a continuous testing device for polyester films. Background Art

[0002] Polyester films are widely used in modern industry, and have excellent mechanical properties, electrical insulation properties, dimensional stability, chemical stability and other characteristics. They are widely used in many fields such as packaging, electronics, electricity, magnetic recording, image recording and printing. However, with the continuous improvement of product quality and performance requirements in these industries, higher requirements are also put forward for the quality inspection of polyester films.

[0003] Traditional polyester film detection methods often have many limitations. For example, some detection methods are intermittent operations, with low detection efficiency and difficult to meet the rapid detection requirements in large-scale production. Moreover, some existing detection equipment has relatively single functions and cannot comprehensively detect multiple key performance indicators of polyester films at the same time. When detecting the passing rate and optical density of the film, the detection effect is poor. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a continuous testing device for polyester films, which solves the problems mentioned above.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A continuous testing device for polyester films, including a testing mechanism arranged on the side of the production line. The testing mechanism includes two lifting cylinders fixed on the production line frame. On one side of the piston rods of the two lifting cylinders facing each other, aluminum profile frames are fixedly connected through L-shaped fixing brackets. On one side of the two aluminum profile frames facing each other, testing grooves are opened;

[0006] A receiving probe is fixedly connected to the inner cavity of the testing groove of the upper aluminum profile frame;

[0007] A light source probe corresponding to the receiving probe is fixedly connected to the inner cavity of the testing groove of the lower aluminum profile frame;

[0008] Wiping components for cleaning the receiving probe and the light source probe respectively are arranged in the inner cavities of the testing grooves of the upper and lower aluminum profile frames;

[0009] Two groups of receiving probes and light source probes are provided, and are respectively arranged in one-to-one correspondence in the upper and lower testing grooves;

[0010] The wiping assembly includes a fixed rod and an external gear ring fixed to the test slot. A central gear driven by a driving mechanism is rotatably connected to the surface of the fixed rod. The central gear meshes with a walking gear that meshes with the inner ring of the external gear ring. The inner cavity of the walking gear is hollow and is fixed with a fixed frame. Two driving wheels driving a wiping belt are rotatably connected to the inner cavity of the fixed frame. A lifting cylinder is fixedly connected to the inner cavity of the fixed frame. The top end of the piston rod of the lifting cylinder is fixedly connected with a connecting frame. Both ends of the connecting frame are fixedly connected with ejector rods that abut against the inner ring of the wiping belt. A suction funnel is fixedly connected to the bottom of the walking gear. A wire reel is fixedly connected to the surface of the fixed rod. A negative pressure suction pipe communicated with a vacuum pump is drivingly connected to the surface of the wire reel. One end of the negative pressure suction pipe is communicated with the inner cavity of the suction funnel. When in use, the produced polyester film is conveyed through the gap between two aluminum profile frames. At this time, the passing rate and light density of the polyester film are detected through the cooperation of a light source probe and a receiving probe. When detecting, dust and other impurities will adhere to the surfaces of the glasses of the light source probe and the receiving probe, and are cleaned by the wiping assembly. The driving motor drives the driving gear to rotate, the driving gear drives the transmission gear to rotate, the transmission gear drives the central gear to rotate around the fixed rod as the center of the circle, and drives the walking gear to move under the probe to be cleaned. At this time, the probe on the other side is vacant for detection. When the walking gear moves under the probe to be cleaned, the lifting cylinder drives the ejector rod to rise, and the wiping belt is lifted upward from both sides. The wiping belt abuts against the surface of the probe glass. At this time, the driving wheel drives the wiping belt to drive and wipe the surface of the probe, and the walking gear rotates reciprocally to rotate itself to effectively wipe the probe glass and improve the detection accuracy.

[0011] As a further scheme of the present invention: A plurality of test slots are provided and are evenly arranged in the inner cavity of the aluminum profile frame for performing point tests on multiple parts of the polyester film.

[0012] As a further scheme of the present invention: The polyester film is arranged between two aluminum profile frames. When the light source probe detects the polyester film, the distance between the two aluminum profile frames is 2 cm.

[0013] As a further scheme of the present invention: Ring-shaped protrusions located on the side of the wiping belt are provided at both ends of the ejector rod. The wiping belt is limited by the ring-shaped protrusions on both sides, and it can be prevented from falling off when its height can be adjusted up and down.

[0014] As a further solution of the present invention: The driving mechanism includes a driving motor fixed to the side of the fixed rod. The output shaft section of the driving motor is fixedly connected with a driving gear. The top of the central gear is fixedly connected with a transmission gear sleeved on the surface of the fixed rod. The transmission gear meshes with the driving gear. When in use, the driving motor drives the driving gear to rotate, the driving gear drives the transmission gear to rotate, and the transmission gear drives the central gear to rotate around the fixed rod as the center of the circle.

[0015] As a further solution of the present invention: The wiping belt is a microfiber lens cloth, which has good dust absorption and softness, and can be used to gently wipe the optical probe to remove dust and slight stains.

[0016] As a further solution of the present invention: The distance between the two ejector rods is greater than the diameters of the probe glasses on the surfaces of the receiving probe and the light source probe, which can effectively wipe the glasses on the surfaces of the receiving probe and the light source probe, ensure the accuracy of its detection, and will not be affected by lens dirt.

[0017] The present invention has the following beneficial effects compared with the prior art:

[0018] When performing detection, the surfaces of the glasses of the light source probe and the receiving probe will be contaminated with dust and other impurities. The wiping assembly is used for cleaning. The traveling gear walks under the probe to be cleaned, the lifting cylinder drives the ejector rod to rise, and the wiping belt is lifted upward from both sides. The wiping belt abuts against the surface of the probe glass, and the driving wheel drives the wiping belt to drive and wipe the surface of the probe. And the traveling gear rotates reciprocally to rotate itself to effectively wipe the probe glass, increasing the detection accuracy.

[0019] The bottom of the traveling gear is fixedly connected with an air suction hopper. The surface of the fixed rod is fixedly connected with a wire winding wheel. The surface of the wire winding wheel is drivingly connected with a negative pressure suction pipe communicated with a vacuum pump. One end of the negative pressure suction pipe is communicated with the inner cavity of the air suction hopper. The negative pressure suction pipe can effectively suck out the impurities on the surface of the wiping belt and ensure the cleanliness of the wiping belt. BRIEF DESCRIPTION OF THE DRAWINGS
