Description

Technical Field

[0001] This utility model relates to the field of polyester screen testing technology, specifically a polyester screen load-bearing testing device. Background Technology

[0002] In industrial production, polyester screens are widely used in mineral screening, food processing, and chemical filtration due to their excellent corrosion resistance, wear resistance, and stable physicochemical properties. Their load-bearing capacity is a key indicator of product quality, and accurate load-bearing testing is crucial for ensuring the safety and reliability of the screens under complex operating conditions.

[0003] In existing technologies, polyester screens employ a woven structure with interlaced warp and weft threads. The intersections of these threads form the basis of their mechanical load-bearing capacity. Traditional testing devices typically only clamp the screen at either the horizontal or vertical ends. Due to the difference in mechanical properties between the warp and weft threads, this method leads to stress concentration when the screen is subjected to force. This causes excessive tensile force on the edges of the screen, resulting in slippage, localized damage, or even screen breakage. Furthermore, uneven stress can cause irregular deformation of the screen during testing, making it difficult to accurately reflect its overall load-bearing capacity. This results in test data deviating from actual values ​​and reducing the accuracy of load-bearing tests. Therefore, a polyester screen load-bearing testing device is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a polyester screen load-bearing testing device to solve the problem mentioned in the background art that the traditional testing device usually clamps the polyester screen at both ends of the horizontal or vertical direction, which can easily cause the polyester screen to slide or be damaged due to uneven force during the test, thus affecting the accuracy of the load-bearing test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyester screen load-bearing testing device, comprising a main frame, a controller fixedly connected to the top surface of the main frame, and a fixed testing component provided on the inner wall of the main frame;

[0006] The fixed test assembly includes a fixing frame, which is fixedly connected to the inner wall of the main frame. The bottom surface of the main frame has a threaded hole, and the inner wall of the threaded hole is threaded with a first threaded post. The surface of the first threaded post is rotatably connected with a movable frame. The inner wall of the main frame is slidably connected with a second threaded post. The lower end of the second threaded post is fixedly connected with a connecting plate. The inner wall of the connecting plate is fixedly connected with a pressure sensor. The bottom surface of the pressure sensor is fixedly connected with a contact plate. The pressure sensor is electrically connected to a controller.

[0008] Preferably, the top surface of the threaded ring is rotatably connected to an L-shaped block, the inner wall of the L-shaped block is movably sleeved with the surface of the second threaded post, and the bottom surface of the L-shaped block is fixedly connected to the top surface of the main frame.

[0009] Preferably, the surface of the second threaded column has two limiting grooves, and the inner wall of the main frame has two limiting blocks fixedly connected, with the limiting blocks slidably connected to the inner wall of the limiting grooves.

[0011] Preferably, both the upper end of the movable frame and the lower end of the fixed frame are fixedly connected with anti-slip rings, and the anti-slip rings are made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The fixed test assembly allows the polyester screen to be placed between the fixed frame and the movable frame.

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.

[0019] Please see Figures 1-3 This utility model provides a polyester screen load-bearing capacity testing device, including a main frame 1. A controller is fixedly connected to the top surface of the main frame 1. A fixed testing component 2 is provided on the inner wall of the main frame 1. The fixed testing component 2 includes a fixed frame 201, which is fixedly connected to the inner wall of the main frame 1. A threaded hole 202 is opened on the bottom surface of the main frame 1. A first threaded post 203 is threadedly connected to the inner wall of the threaded hole 202. A movable frame 204 is rotatably connected to the surface of the first threaded post 203. A second threaded post 205 is slidably connected to the inner wall of the main frame 1. A connecting plate 206 is fixedly connected to the lower end of the second threaded post 205. A pressure sensor 207 is fixedly connected to the inner wall of the connecting plate 206. A contact plate 208 is fixedly connected to the bottom surface of the sensor 207. The pressure sensor 207 is electrically connected to the controller. Through the fixed test assembly 2, the polyester screen is placed between the fixed frame 201 and the movable frame 204. The first threaded column 203 is rotated to move the movable frame 204. The movable frame 204 clamps and fixes the polyester screen between the movable frame 204 and the fixed frame 201. The fixed frame 201 and the fixed frame 202 are both matched circular designs, which facilitates the formation of a uniform circular clamping force when clamping and fixing the polyester screen. This prevents the polyester screen from sliding or being damaged due to uneven force during testing, and improves the accuracy of the polyester screen load-bearing test.

[0020] Furthermore, a drive column 212 is rotatably connected to the inner wall of the main frame 1, and a threaded ring 213 is threadedly connected to the surface of the second threaded column 205. Synchronous pulleys 214 are fixedly connected to the surface of the threaded ring 213 and the surface of the drive column 212. The same synchronous belt 215 is sleeved on the surface of the two synchronous pulleys 214. Through the cooperation of the drive column 212, the threaded ring 213 and the synchronous pulleys 214, the rotation of the drive column 212 drives the threaded ring 213 to rotate through the cooperation of the synchronous pulleys 214 and the synchronous belt 215. The rotation of the threaded ring 213 drives the second threaded column 205 to move. The movement of the second threaded column 205 facilitates the connection plate 206, the pressure sensor 207 and the contact plate 208 to perform load-bearing tests on the polyester screen between the fixed frame 201 and the moving frame 204.

[0021] Furthermore, an L-shaped block 217 is rotatably connected to the top surface of the threaded ring 213. The inner wall of the L-shaped block 217 is movably sleeved with the surface of the second threaded post 205, and the bottom surface of the L-shaped block 217 is fixedly connected to the top surface of the main frame 1. The L-shaped block 217 is used to limit the threaded ring 213, so that the threaded ring 213 can be kept in the same position when rotating.

[0022] Furthermore, two limiting grooves 210 are provided on the surface of the second threaded post 205, and two limiting blocks 211 are fixedly connected to the inner wall of the main frame 1. The limiting blocks 211 are slidably connected to the inner wall of the limiting grooves 210. The limiting grooves 210 and the limiting blocks 211 cooperate with each other to facilitate the limiting of the second threaded post 205 and prevent the second threaded post 205 from rotating when the threaded ring 213 rotates.

[0023] Furthermore, a motor 216 is fixedly connected to the side wall of the main frame 1, and the surface of the drive column 212 is fixedly connected to the output end of the motor 216. The motor 216 is electrically connected to the controller. By setting the motor 216, the output end of the motor 216 rotates, thereby driving the drive column 212 to rotate. The rotation of the drive column 212 drives the second threaded column 205 to move.

[0024] Furthermore, both the upper end of the movable frame 204 and the lower end of the fixed frame 201 are fixedly connected with anti-slip rings 209. The anti-slip rings 209 are made of rubber. The rubber anti-slip rings 209 facilitate the increase of friction when in contact with the polyester screen, thereby improving the stability of the clamping.

[0025] Working principle: During use, the polyester screen is placed between the fixed frame 201 and the movable frame 204. The first threaded column 203 is rotated to move the movable frame 204. The movable frame 204 clamps and fixes the polyester screen between the movable frame 204 and the fixed frame 201. Both the fixed frame 201 and the fixed frame 204 are matched with a circular design, which facilitates the formation of a uniform circular clamping force when clamping and fixing the polyester screen. This prevents the polyester screen from sliding or being damaged due to uneven force during testing, and improves the accuracy of the polyester screen load-bearing test.

[0026] Simultaneously, the controller starts the motor 216, and the output end of the motor 216 rotates, driving the drive column 212 to rotate. The rotation of the drive column 212, through the cooperation of the synchronous pulley 214 and the synchronous belt 215, drives the threaded ring 213 to rotate. The rotation of the threaded ring 213, through the cooperation of the limiting groove 210 and the limiting block 211, drives the second threaded column 205 to move. The movement of the second threaded column 205 facilitates the connection plate 206, the pressure sensor 207 and the contact plate 208 to perform a load-bearing test on the polyester screen between the fixed frame 201 and the moving frame 204.
