Description

Technical Field

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

[0002] Hot melt adhesive sheet performance testing is a quality control process that verifies whether hot melt adhesive sheets meet the requirements for use in terms of adhesion, environmental resistance, and physical properties through a series of professional tests. The core purpose of this test is to ensure that hot melt adhesive sheets can stably perform their adhesive function in practical applications (such as clothing, footwear, and packaging) and avoid problems such as delamination and detachment.

[0003] An investigation revealed that a utility model patent discloses a device for testing the tensile properties of hot melt adhesive sheets (publication number: CN220251559U), comprising a workbench with a clamping assembly at its upper end, frames fixedly mounted on both sides of the workbench, a top cover fixedly mounted on the upper end of the frames, a fixing plate fixedly mounted on the upper end of the top cover, a telescopic rod fixedly mounted on the inner side of the upper end of the fixing plate, a driven gear rotatably connected to one end of the telescopic rod, a main gear meshing with one side of the driven gear, a rotating shaft fixedly mounted on the lower end of the main gear, a second motor rotatably connected to the lower end of the rotating shaft, the second motor fixedly mounted on the upper end of the top cover, the driven gear penetrating the top cover and rotatably connected to it, a cylinder fixedly mounted on the lower end of the driven gear, a bracket provided on the outside of the cylinder, clamping rods connected to bearings on both sides of the bracket, and a support fixedly mounted on the outside of the cylinder. This utility model is characterized by its strong practicality and automatic stretching capability.

[0004] Although the aforementioned patent uses components such as a top cover, telescopic rod, and multiple motors to clamp and pull the film during the film testing process, thereby testing the film's performance, the large size of the film and the fact that the component only clamps the film at a single point make it prone to inaccurate test data due to the small testing area.

[0005] Therefore, this utility model provides a device for testing the tensile properties of hot melt adhesive sheets to solve the above problems. Utility Model Content

[0006] This invention provides a device for testing the tensile properties of hot melt adhesive sheets, aiming to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A device for testing the tensile properties of hot melt adhesive sheets includes a chamber and a testing machine.

[0013] As a preferred technical solution of this application, a data analyzer is installed on the outer wall of the testing machine, and the data analyzer is electrically connected to the testing machine via an electrical signal.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a device for testing the tensile properties of hot melt adhesive sheets, such as... Figures 1-5 As shown, the hot melt adhesive sheet tensile property testing device includes a chamber 1 and a testing machine 2. The chamber 1 is installed on the top of the testing machine 2, and the testing components are installed inside the chamber 1. The detection assembly includes a heat insulation plate 3 installed at the bottom of the machine compartment 1. A displacement seat 4 is slidably connected to the inner wall of the heat insulation plate 3. There are multiple displacement seats 4. A base plate 5 is installed on the top of each displacement seat 4. A slide plate 7 is installed on the top of the base plate 5 through a sliding shaft 6. A pressure plate 8 is rotatably connected to the outer wall of the slide plate 7 through a hinge. The bottom of the pressure plate 8 is fixedly connected to the top of the heat insulation plate 3 through a compression spring 9. Electromagnets 10 are installed inside the base plate 5 and the pressure plate 8.

[0019] The outer walls of the base plate 5 and the pressure plate 8 are coated with an anti-stick coating. A handle is fixedly connected to the top of the pressure plate 8, and a traction component is installed on the outer wall of the base plate 5.

[0020] The traction assembly includes a threaded seat 11 fixedly connected to the outer wall of the displacement seat 4. The inner walls of the two threaded seats 11 are threaded with a bidirectional lead screw 12. The outer wall of the machine compartment 1 is equipped with a drive motor 13. The output end of the drive motor 13 is coaxially driven with the end of the bidirectional lead screw 12 through a coupling sleeve.

[0021] Specifically, the hot melt adhesive sheet can be placed in the machine compartment 1, and the inspection machine 2 can inspect the sheet. The inspection components work together to detect various parameters of the sheet, improving the comprehensiveness of the inspection data. Two base plates 5 and pressure plates 8, each equipped with an electromagnet 10, clamp the sheet using the magnetic attraction of the electromagnets 10, thus detecting its elastic deformation. The sliding displacement seat 4, in conjunction with the drive motor 13, drives the two threaded seats 11 to move in opposite directions via the bidirectional lead screw 12. The movement allows for testing the film's tear resistance, while the deformation performance is tested. Magnetic attraction causes the pressure plate 8 to press downwards. When the test ends and the magnetic force is released, the compression spring 9 causes the slide plate 7 and pressure plate 8 to rise. The openable pressure plate 8 allows for easy placement of the entire film for rapid testing. This component has a simple structure and high practicality. It can perform multiple parameter tests on the film through simple component combinations. The large clamping area also avoids incomplete test data, further improving the comprehensiveness and accuracy of film testing.

[0022] A detector 14 is installed on the outer wall of the machine compartment 1. The two signal terminals of the detector 14 are fixedly connected to the control terminals of the electromagnet 10 and the drive motor 13 through the signal line 15 and the control line 16, respectively.

[0023] A temperature controller 17 is installed on the inner wall of the cabin 1. A heating tube 18 is installed at the output end of the temperature controller 17. There are several heating tubes 18.

[0024] Specifically, the detector 14 on the outer wall of the machine compartment 1 can obtain working parameters from the drive motor 13 and electromagnet 10 through the signal line 15 and control line 16, thereby analyzing the detection data. The temperature controller 17 on the inner wall of the machine compartment 1 can quickly adjust the temperature during detection through temperature control, thereby quickly adjusting the detection conditions to detect various limit parameters of the film and further improve the comprehensiveness of the detection.

[0025] The outer wall of the cabin 1 is connected to a door 19 via a hinge. A transparent observation window 20 is installed on the outer surface of the door 19, and a handle is fixedly connected to the outer surface of the door 19.

[0026] A data analyzer 21 is installed on the outer wall of the testing machine 2. The data analyzer 21 is electrically connected to the testing instrument 14 via an electrical signal.

[0027] Specifically, the door 19 allows operators to easily open the machine compartment 1 to place the test film, while the transparent observation window 20 allows operators to observe the testing process in real time, thereby improving the control accuracy of the test. The data analyzer 21 on the outer wall of the testing machine 2 can quickly analyze the test data, thereby displaying whether the test results are qualified, which facilitates the operator to record the data.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
