Description

Technical Field

[0001] This utility model relates to the field of membrane testing technology, specifically a transfer membrane defect detection device. Background Technology

[0002] Transfer film is an intermediate carrier that exists on a transfer paper or plastic base, carrying the printed or printed pattern. It is a layer of chemically elastic film used for transferring the image onto the printed object. Transfer film is widely used in advertising, decoration, and other applications.

[0003] During the production of transfer films, defect detection is typically required to ensure quality before packaging and shipment. This necessitates the use of transfer film defect detection equipment. Currently, existing transfer film defect detection equipment has the following shortcomings: it lacks dust removal treatment for the transfer film surface. During production, dust, lint, and other impurities easily adhere to the surface of the transfer film, affecting the detection results and accuracy. To address these issues, we propose a new transfer film defect detection device. Utility Model Content

[0004] The purpose of this invention is to provide a transfer film defect detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transfer film defect detection device, comprising:

[0006] A testing platform is provided, with a light detector installed in the middle. A mounting plate is fixedly installed on the top wall near the rear end of the testing platform. Two first guide rollers and two second guide rollers are rotatably mounted on the mounting plate. A dust removal mechanism is provided on one side of one of the second guide rollers. The dust removal mechanism includes two cleaning rollers. A through groove is provided on the mounting plate, and an adjustment seat is provided in the through groove. One cleaning roller is rotatably mounted on the mounting plate below the through groove via a rotating shaft, and the other cleaning roller is rotatably mounted on the adjustment seat via a rotating shaft. Two drive motors are provided on the rear side of the mounting plate. One drive motor is fixedly mounted on the mounting plate, and the other drive motor is fixedly mounted on the adjustment seat. The output ends of the two drive motors are respectively connected to the rotating shafts of the two cleaning rollers.

[0007] Preferably, the front side of the mounting plate is provided with two dust suction hoods, which are respectively located on the upper and lower sides of the two cleaning rollers. One dust suction hood is fixedly installed on the front side wall of the mounting plate, and the other dust suction hood is fixedly installed on the front side wall of the adjusting seat. A dust suction pipe is fixedly installed on the dust suction hood, and both dust suction pipes are connected to an external dust collection device through conduits.

[0008] Preferably, the through groove has two fixed rods welded to it, the adjusting seat is slidably connected to the fixed rods through the through hole, a connecting seat is fixedly welded to the rear side wall of the adjusting seat, a mounting seat is fixedly welded to the rear side wall of the mounting plate, an electric telescopic rod is fixedly installed on the mounting seat, and the connecting seat is fixedly installed at the top of the electric telescopic rod.

[0009] Preferably, an antistatic rod is mounted on the mounting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In use, before testing, the transfer film can be cleaned by two cleaning rollers driven by two drive motors. This removes dust, lint and other impurities adhering to the surface of the transfer film, thus avoiding the influence of dust, lint and other impurities on the test results and greatly improving the accuracy of defect detection of the transfer film. The dust suction hood can generate negative pressure suction through the dust suction pipe and external dust suction equipment to suck in the dust, lint and other impurities cleaned by the cleaning rollers, thus preventing the dust, lint and other impurities from being dispersed and adhering to the transfer film again.

[0012] 2. The electric telescopic rod provided in this utility model can drive the adjusting seat to rise and fall in the through groove, thereby adjusting the distance between the two cleaning rollers, which facilitates dust removal treatment of transfer films of different thicknesses and improves the applicability of the device.

[0021] Two dust suction hoods 7 are provided on the front side of the mounting plate 3. The two dust suction hoods 7 are respectively located on the upper and lower sides of the two cleaning rollers 6. One dust suction hood 7 is fixedly installed on the front side wall of the mounting plate 3, and the other dust suction hood 7 is fixedly installed on the front side wall of the adjusting seat 10. A dust suction pipe 8 is fixedly installed on the dust suction hood 7. Both dust suction pipes 8 are connected to an external dust suction device through conduits. The dust suction hood 7 can generate negative pressure suction through the dust suction pipe 8 and the external dust suction device to suck in the dust, lint and other impurities cleaned by the cleaning rollers 6, so as to prevent the dust, lint and other impurities from being dispersed and adhering to the transfer film again.

[0022] Two fixed rods 12 are fixedly welded to the through groove 9. The adjusting seat 10 is slidably connected to the fixed rods 12 through the through holes. A connecting seat 13 is fixedly welded to the rear side wall of the adjusting seat 10. An mounting seat 14 is fixedly welded to the rear side wall of the mounting plate 3. An electric telescopic rod 15 is fixedly installed on the mounting seat 14. The connecting seat 13 is fixedly installed at the top of the electric telescopic rod 15.

[0023] The mounting plate 3 is equipped with an electrostatic eliminator 16, which facilitates the removal of static electricity from the transfer film.

[0024] Working principle: In use, the transfer film is conveyed on the first guide roller 4 and the second guide roller 5 by an external traction device. During the conveying process, the transfer film is inspected for defects by a light detector 2. Before inspection, the two sides of the transfer film are cleaned by two cleaning rollers 6 driven by two drive motors 11 to remove dust, lint and other impurities attached to the surface of the transfer film. This avoids the dust, lint and other impurities attached to the surface of the transfer film from affecting the inspection results, and greatly improves the accuracy of defect detection of the transfer film. The dust suction hood 7 can generate negative pressure suction through the dust suction pipe 8 and the external dust suction device to suck in the dust, lint and other impurities cleaned by the cleaning rollers 6, and prevent the dust, lint and other impurities from being dispersed and attached to the transfer film again.
