Description

Technical Field

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

[0002] Hot melt adhesive film is widely used in the packaging industry for sealing boxes, bags, and cartons. It can quickly and efficiently bond materials such as cardboard, paper, and plastic films, providing a strong sealing effect. For hot melt adhesive film applications, flatness testing is often crucial. Flatness refers to the smoothness or evenness of the surface when the hot melt adhesive film is applied to the target surface. Flatness directly affects the contact area and quality between the hot melt adhesive film and the target surface. If the hot melt adhesive film does not adhere smoothly to the target surface, the contact area will be reduced, thus affecting the strength and durability of the bond.

[0003] The specification of a TPU hot melt adhesive film testing device in the prior art (publication number CN222166084U) mentions "a testing table having a placement surface for placing the TPU hot melt adhesive film to be tested; a moving component disposed on the testing table; and a testing component disposed on the moving component, the testing component including a rolling element rotatable relative to the moving component and a plurality of testing heads arranged circumferentially along the rolling element; wherein the moving component moves in a direction parallel to the placement surface to drive the testing component to test the flatness of the TPU hot melt adhesive film to be tested placed on the placement surface." However, the testing device in the prior art is not stable or accurate during testing, the object being tested is prone to movement, and the feeding and unloading are not fast and convenient, affecting the efficiency of the testing work. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a TPU hot melt adhesive film testing device is provided to solve the problems of unstable and inaccurate testing, easy movement of the tested object, and slow and inconvenient feeding, which affect the efficiency of testing.

[0005] To achieve the above objectives, a TPU hot melt adhesive film testing device is provided, comprising a lower fixed plate and a testing platform. A first Y-linear guide rail is provided in the middle of the lower fixed plate, and a transport platform is slidably connected to the first Y-linear guide rail. Lower sleeve plates are fixed at both ends of the lower fixed plate, and a side support plate is fixed at the upper end of the lower sleeve plate. An upper sleeve plate is fixed at the upper end of the side support plate, and the upper sleeve plate is fitted over the outer end of the upper fixed plate. A second X-linear guide rail is provided on the lower side of the upper fixed plate, and a testing platform is movably mounted on the second X-linear guide rail.

[0006] Furthermore, a support leg is fixed to the lower end of the lower sleeve plate, and a base is fixed to the lower end of the support leg; the upper sleeve plate and the lower sleeve plate are arranged parallel to each other.

[0007] Furthermore, a first slider is provided at the lower part of the transport platform, and the first slider is slidably connected to the first Y linear guide rail. A first X linear guide rail is provided on both the left and right sides of the upper end face of the transport platform, and a second slider is slidably connected to the first X linear guide rail.

[0008] Furthermore, a side moving plate is fixed to the upper end of the second slider, a fixing block is fixed to the lower part of the inner side of the side moving plate, and a first telescopic cylinder is fixed to the upper end of the fixing block. The upper end of the first telescopic cylinder is fixed to the lower clamping plate, and an upper clamping plate is fixed to the upper part of the inner side of the side moving plate.

[0009] Furthermore, the upper clamping plate and the lower side, as well as the upper side of the lower clamping plate, are each provided with multiple sets of anti-slip blocks, and the anti-slip blocks are made of silicone rubber. The lower clamping plate can move up and down in the vertical direction.

[0010] Furthermore, side hanging plates are fixed on both the left and right sides of the lower end face of the upper fixed plate. A second Y linear guide rail is provided on the lower part of the inner side of the side hanging plate, and a fourth slider is slidably connected inside the second Y linear guide rail. The fourth slider is fixed to the outer end of the second X linear guide rail, and a third slider is provided on the upper part of the detection platform. The third slider is slidably connected to the second X linear guide rail.

[0011] Furthermore, the lower end face of the testing platform is fixed with a second telescopic cylinder on both the left and right sides. The lower end of the second telescopic cylinder is fixed to the mounting plate, and a flatness detector and an infrared gap detector are installed on the lower end face of the mounting plate. The mounting plate can move up and down in the vertical direction.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model facilitates feeding operations by having the first slider slide on the first Y linear guide rail, and facilitates relative movement of the left and right side moving plates by having the second slider slide on the first X linear guide rail. This allows the left and right sides of the TPU hot melt adhesive film to be held by the anti-sliding blocks on the left and right sides and the lower clamping plate, thereby ensuring the stability of the test.

[0014] 2. The clamping mechanism is safer and more secure, making it less prone to slippage and ensuring safer and more reliable testing.

[0015] 3. In this utility model, the fourth slider moves back and forth within the second Y linear guide rail, and the third slider moves left and right on the second X linear guide rail, thereby driving the detection platform to move synchronously, which facilitates flexible changes in the detection position.

[0016] 4. This utility model utilizes the telescopic movement of the second telescopic cylinder to drive the mounting plate, flatness detector, and infrared gap detector to move up and down synchronously, thereby changing the detection height position. The flatness detector performs multiple checks on the flatness of the TPU hot melt adhesive film, and the infrared gap detector detects the integrity of the TPU hot melt adhesive film surface, making the detection more accurate and reliable.
