Description

Technical Field

[0001] This utility model relates to the field of canvas tension testing technology, and in particular to a canvas tension testing stretching device. Background Technology

[0002] Canvas is a relatively thick cotton or linen fabric, named for its original use in sails. It is generally made with a plain weave, with a small amount using a twill weave. Both warp and weft yarns are multi-ply. As an important textile material, the stability and uniformity of canvas tension are crucial to its performance. Therefore, a canvas tension testing device is needed to detect the tension of canvas. However, existing devices still have certain shortcomings in use, such as:

[0003] When the device is in use, during the stretching process of the canvas, it is necessary to continuously record the tensile force and elongation to measure the strength data of the canvas. However, during the stretching process, external wind, such as the wind caused by a person passing by, the wind from a fan, or the wind from an air conditioner, may blow onto the surface of the canvas, causing the canvas to shake from side to side. This may result in a larger tensile force being required to break the canvas, leading to errors in the data. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by proposing a canvas tension testing stretching device, which improves the problem that the data of existing canvas tension testing stretching devices are prone to errors.

[0005] A canvas tension testing device includes a base, a protective shell, a support plate, and a support frame: the upper end of the base is provided with a protective shell, the side of the protective shell is provided with a support frame, the upper end of the protective shell is provided with a support plate, and the upper end of the base is provided with a tensioning structure.

[0006] The tensioning structure includes a motor, a threaded rod, and a movable plate. The upper end of the support plate is provided with a motor, the lower end of the motor is provided with a threaded rod, and the surface of the threaded rod is provided with a movable plate.

[0007] Preferably, a controller is provided at the upper end of the movable plate, an upper fixing block is provided at the lower end of the movable plate, and a support base is provided at the upper end of the base.

[0008] Preferably, the upper end of the support base is provided with a lower fixing block, and both the upper and lower fixing blocks are provided with hydraulic rods on their sides, with clamping blocks provided on the sides of the hydraulic rods.

[0009] Preferably, the clamping block has a limiting protrusion on its side, the lower fixed block has a load-bearing block at its lower end, the support base has a button inside, and the lower fixed block has a limiting post at its lower end.

[0010] Preferably, a limit block is provided on the side of the movable plate, and a limit rod is provided inside the support frame, with the limit rod passing through the limit block.

[0011] Preferably, a cover is provided on the side of the protective shell, the cover is slidably connected to the protective shell, and a magnet is provided on the side of the protective shell.

[0012] Preferably, the movable plate is threadedly connected to the threaded rod, the limiting post is slidably connected to the support seat, and the hydraulic rod passes through the upper fixed block and the lower fixed block.

[0013] The beneficial effects of this utility model are:

[0014] 1. By designing a protective outer shell, lid, and magnetic blocks, when the device is in use, the lid is first pulled outwards using the handle on the lid surface. Then, the canvas to be tested is fixed inside the device, and the lid is closed inwards again, so that the magnetic blocks on the sides of the two lids are attached together. The magnetic blocks attract each other to fix the lid in place. This, through the cooperation of the protective outer shell and lid, keeps the canvas in a sealed environment, reducing the influence of the external environment on the canvas, thereby preventing the impact on the canvas strength data and improving the accuracy of the device data.

[0015] 2. By setting two upper and lower fixing blocks inside the device, the device can simultaneously detect two canvases when multiple canvases need to be measured, thereby reducing detection time and improving detection efficiency. Furthermore, when measuring two canvases, the data of the two canvases can be compared to ensure data accuracy and improve the practicality of the device. Attached Figure Description

[0021] 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.

[0022] In practical implementation: such as Figure 1-4 As shown, a canvas tension testing device includes a base 1, a protective shell 2, a support plate 3 and a support frame 21: the upper end of the base 1 is provided with the protective shell 2, the side of the protective shell 2 is provided with the support frame 21, the upper end of the protective shell 2 is provided with the support plate 3, and the upper end of the base 1 is provided with a tension structure 22.

[0023] The tensioning structure 22 includes a motor 6, a threaded rod 7 and a movable plate 8. The upper end of the support plate 3 is provided with the motor 6, the lower end of the motor 6 is provided with the threaded rod 7, and the surface of the threaded rod 7 is provided with the movable plate 8.

[0024] When the device is in use, first fix the canvas to be tested, then turn on the motor 6 to drive the threaded rod 7 to rotate, so that the movable plate 8 moves on the surface of the threaded rod 7, thereby pulling the canvas upward to perform a tensile test on the canvas, achieving the purpose of pulling the canvas and eventually breaking it.

[0025] A controller 11 is provided at the upper end of the movable plate 8, an upper fixing block 12 is provided at the lower end of the movable plate 8, and a support base 16 is provided at the upper end of the base 1.

[0026] The upper end of the support base 16 is provided with a lower fixing block 19, and the sides of both the upper fixing block 12 and the lower fixing block 19 are provided with hydraulic rods 13, and the sides of the hydraulic rods 13 are provided with clamping blocks 14.

[0027] When the device is in use, first place the canvas inside the upper fixing block 12 and the lower fixing block 19, and position the canvas in the middle of the two clamping blocks 14. Then, open the hydraulic rod 13, so that the hydraulic rods 13 on both sides simultaneously push the clamping blocks 14 to move, so that the clamping blocks 14 on both sides move inward at the same time, so that the clamping blocks 14 clamp and fix the canvas, and make the limiting protrusions 15 on the side of the clamping blocks 14 fit with the canvas and form a staggered fit, thereby increasing the contact area with the canvas, improving the friction, making the canvas more stable, and preventing the canvas from falling off during the stretching process.

[0028] The clamping block 14 is provided with a limiting protrusion 15 on its side, the lower end of the lower fixing block 19 is provided with a load-bearing block 18, the support base 16 is provided with a button 17 inside, and the lower end of the lower fixing block 19 is provided with a limiting post 20.

[0029] When the device is in use, the canvas is first fixed inside the device, and then a tensile test is performed on the canvas. At this time, the tension of the canvas pulls the lower fixing block 19 upward. At this time, the button 17 is raised but not triggered, and is limited by the limit post 20 to prevent the lower fixing block 19 from coming off the upper end of the support base 16. When the canvas breaks, the lower fixing block 19 loses tension and moves downward, colliding with the button 17 and pressing it down. This causes the button 17 to trigger the controller 11, which shuts down the motor 6, stopping the device from stretching. This prevents the device from continuing to operate and record data after the canvas breaks, which could lead to serious data errors. Furthermore, by setting two upper fixing blocks 12 and two lower fixing blocks 19, the device can simultaneously test two canvases and compare the data of the two canvases under the same environment, making the data more accurate.

[0030] A limit block 10 is provided on the side of the movable plate 8, and a limit rod 9 is provided inside the support frame 21, with the limit rod 9 passing through the limit block 10;

[0031] When the device is in use, the movable plate 8 drives the limiting block 10 to move up and down, so that the limiting block 10 moves up and down on the surface of the limiting rod 9, and the limiting rod 9 limits the limiting block 10 to prevent the movable plate 8 from tilting or deviating during the movement.

[0032] A cover 4 is provided on the side of the protective shell 2. The cover 4 is slidably connected to the protective shell 2. A magnet 5 is provided on the side of the protective shell 2.

[0033] The movable plate 8 is threadedly connected to the threaded rod 7, the limiting post 20 is slidably connected to the support base 16, and the hydraulic rod 13 passes through the upper fixed block 12 and the lower fixed block 19.

[0034] When the device is in use and the canvas needs to be tested, the cover 4 is opened by pulling open the handle, and then the canvas is fixed inside the device. The cover 4 is then closed again and fixed by the magnetic blocks 5 adhering to each other. The protective shell 2 and the cover 4 protect the canvas, keeping it in a sealed environment and preventing the external environment from affecting the test data of the canvas.

[0035] In use, this invention first opens the box cover 4, then places the upper and lower ends of the canvas to be tested between the clamping blocks 14 inside the upper fixing block 12 and the lower fixing block 19, respectively. Next, the hydraulic rod 13 is opened, causing it to push the clamping blocks 14 to clamp and fix the canvas. Then, the box cover 4 is closed, allowing the magnetic blocks 5 to attract each other and fix the cover 4. Then, the motor 6 is turned on, causing the threaded rod 7 to rotate, which moves the movable plate 8 upwards on the surface of the threaded rod 7, thereby pulling the canvas upwards and causing it to lift the lower fixing block 19, thus lifting the load-bearing block. When button 18 is not in contact with button 17, button 17 pops up, and then movable plate 8 continues to move upward to detect the tension of the canvas and record the data during the process. Then, when the canvas breaks, the lower fixed block 19 loses tension and falls downward, causing the load-bearing block 18 to press button 17 down. Button 17 triggers controller 11, which shuts down motor 6 and stops recording data to prevent the device from continuing to move upward and causing data errors. Then, the staff saves the data, opens the box cover 4, takes out the broken canvas, and performs the next test.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
