Description

Technical Field

[0001] This utility model relates to the field of adhesive film testing technology, specifically a device for testing the aging of hot melt adhesive films. Background Technology

[0002] Hot melt adhesive film, as an adhesive material widely used in packaging, textiles, electronics and other industries, will gradually age due to environmental factors (such as light) during use, resulting in a decline in adhesive performance and affecting the quality and service life of products.

[0003] Traditional hot melt adhesive film aging testing devices require operators to stretch the test tank by hand, which is time-consuming and laborious. The test tank needs to be heated inside the device, which generates high temperatures, causing burns to the hands and creating significant safety hazards. Furthermore, the existing devices have limited functionality and cannot perform stretching tests on multiple hot melt adhesive films simultaneously. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hot melt adhesive film aging detection device, which has advantages such as saving time and effort and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned time-saving and labor-saving objectives, this utility model provides the following technical solution: a hot melt adhesive film aging detection device, comprising a detection chamber and a detection tank, wherein a control panel is installed on the right side of the front wall of the detection chamber, and an ultraviolet lamp is installed at the top of the inner wall of the detection chamber; A second drive motor is installed at the rear of the detection chamber. A second ball screw is mounted on the second drive motor via a coupling. A screw slide is mounted on the second ball screw. Horizontal plates are installed on both sides of the screw slide. Base rods are installed at both ends of the horizontal plates. The upper ends of the base rods are fixedly connected to the detection groove.

[0006] As a further improvement of this utility model: a tensile testing mechanism is installed on the upper left side of the testing groove, a connecting frame is installed on the left side wall of the tensile testing mechanism, a first drive motor is installed on the left side of the inner side wall of the testing groove, a first ball screw is installed on the first drive motor through a coupling, a screw slide is driven on the first ball screw, and a screw slide is driven on the screw slide. Both ends of the screw slide are fixedly connected to the connecting frame. When the first drive motor is started, the first drive motor drives the first ball screw to rotate through the coupling, which drives the screw slide to move to the left, drives the connecting frame to move to the left, and drives the tensile testing mechanism to move to the left. Tensile testing can be performed on multiple hot melt adhesive films simultaneously, providing rich functionality.

[0007] As a further improvement of this utility model: a clamping seat is installed on the upper right side of the detection slot, and multiple placement slots are provided on the upper end of the clamping seat. A connecting plate is installed on the upper part of the inner side wall of each placement slot, and two springs are installed on the lower end of each connecting plate. A pressure plate is installed on the lower end of each spring. The pressure plate is made of iron sheet, which can realize the detection of multiple hot melt adhesive films at the same time, and facilitates comparison.

[0008] As a further improvement of this utility model: an electromagnetic lock is provided at the bottom of the placement groove. The electromagnetic lock is magnetically connected to the pressure plate. When the electromagnetic lock is activated, the pressure plate is attracted and the hot melt adhesive film is clamped to prevent it from falling off during stretching.

[0009] As a further improvement of this utility model, a base is installed at each of the four corners of the lower end of the detection box. There are four bases, which support the detection box and improve its stability.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the second drive motor is started, and the second ball screw is driven to rotate through the coupling. This causes the screw slide to move forward, which in turn causes the two horizontal plates to move forward, thereby causing the detection groove to move forward. This replaces the manual stretching by the operator, saving time and effort, and preventing high-temperature burns and reducing safety hazards.

[0011] 2. In this utility model, the first drive motor is started, and the first drive motor drives the first ball screw to rotate through the coupling, which drives the screw slide to move to the left, drives the connecting frame to move to the left, and drives the tensile testing mechanism to move to the left, so as to perform tensile testing on multiple hot melt adhesive films at the same time, with rich functionality.

A first drive motor 4 is installed on the left side of the inner wall of the testing tank 3. A first ball screw is mounted on the first drive motor 4 via a coupling. A screw slide is mounted on the first ball screw, and both ends of the screw slide are fixedly connected to the connecting frame 5. When the first drive motor 4 is started, it drives the first ball screw to rotate via the coupling, causing the screw slide to move to the left, which in turn moves the connecting frame 5 to the left, and the tensile testing mechanism 6 to the left. This allows for simultaneous tensile testing of multiple hot melt adhesive films, providing rich functionality. The upper right side of the testing tank 3... A clamping seat 16 is installed, with multiple placement slots 12 on the upper end of the clamping seat 16.

A base 2 is installed at each of the four corners of the lower end of the testing box 1. There are four bases 2, which support the testing box 1 and improve its stability.

[0018] The working principle of this utility model is as follows: The power cord is connected to the power supply to ensure the device is powered on. Operation is performed on the control panel 7. The second drive motor 8 starts, driving the second ball screw 10 to rotate via the coupling. This causes the screw slide to move forward, which in turn moves the two horizontal plates 9 forward, thereby moving the testing groove 3 forward. This replaces manual stretching by the operator, saving time and effort, preventing burns from high temperatures, and reducing safety hazards. The left ends of multiple hot melt adhesive films are inserted into the tensile testing mechanism 6, and the right ends are placed into the placement groove 12. The electromagnetic lock 13 is activated, attracting the pressure plate 14 and clamping the hot melt adhesive films. The testing chamber 1 is activated, and the ultraviolet lamps irradiate and age the hot melt adhesive film samples. The first drive motor 4 is activated, driving the first ball screw to rotate via the coupling. This causes the screw slide to move to the left, which in turn moves the connecting frame 5 to the left, and the tensile testing mechanism 6 to the left, simultaneously performing tensile testing on multiple hot melt adhesive films.
