Description

Technical Field

[0001] This utility model relates to the technical field of wire mesh tension meter calibration devices, specifically a wire mesh tension meter calibration device. Background Technology

[0002] A screen tension meter is an instrument used to measure the tension of the warp and weft threads in a screen printing stencil. It is widely used in screen printing and is an important tool for inspecting the quality of screen printing. The screen tension meter utilizes the principle of static balance, measuring the tension of the screen by measuring the relative displacement between the measuring head and the supporting foot. The screen tension meter calibration device consists of a device that can control and measure tension in two orthogonal directions and a screen of specified dimensions. It can be used to calibrate the indication error of the screen tension meter. Currently, the calibration methods used in China for screen tension meters include the standard screen method, the dial indicator displacement measurement method, and the single-filament loading comparison method. The dial indicator displacement measurement method is relatively cumbersome, requires certain experience, and places high demands on the calibration personnel. The standard screen method involves applying force to the screen using a tensioning device, then fixing the screen to generate a set of standard tension values, which are used to calibrate the screen tension meter. A force sensor measures the force value, and calipers are used to measure the effective width of the screen, allowing the screen tension to be calculated.

[0003] The fixed point of the existing wire mesh tension meter calibration device is not on the same horizontal line as the wire mesh measurement point. It is impossible to adjust the position of the fixed point of the wire mesh tension meter calibration device according to the wire mesh measurement point. When the fixed point and the wire mesh measurement point are not on the same horizontal line, the tension of the wire mesh may be different at different positions due to the effects of gravity and bidirectional tension. This will cause the tension value measured at the measurement point to deviate from the actual tension value, thus affecting the accuracy of calibration. Since the position of the fixed point cannot be adjusted according to the wire mesh measurement point, the operator needs to take additional measures to ensure the accuracy of the measurement point during the calibration process, which not only increases the complexity of the operation, but may also introduce additional errors.

Four pneumatic cylinders are mounted on the outer surface of the wire mesh tension meter calibration machine.

[0012] Compared with the prior art, this utility model provides a wire mesh tension meter calibration device, which has the following beneficial effects:

[0013] 1. This wire mesh tension gauge calibration device, through the cooperation of a limiting plate, limiting groove, limiting column, second limiting slide rail, and second limiting slider, ensures that the position of the rubber pressure head on the outside of the electric telescopic rod is the same distance from the wire mesh measurement point. The rubber pressure head can be accurately positioned on the wire mesh measurement point, ensuring that each measurement point receives a consistent fixing force, which helps reduce measurement errors and improves the accuracy and reliability of calibration. The uniform pressure distribution helps maintain the flatness and tension uniformity of the wire mesh.

[0014] 2. This wire mesh tension meter calibration device ensures that the plane of the clamping plate is on the same horizontal plane as the wire mesh tension meter calibration machine.

The horizontally placed wire mesh end face is easy to observe and measure, improving the accuracy and reliability of calibration and helping to maintain the integrity and service life of the wire mesh. The flat placement method also reduces the risk of wire mesh wear and breakage caused by unevenness. When the wire mesh end face and the calibration machine plane are on the same horizontal plane, the relative positions between measurement points are more stable, which helps to obtain consistent measurement results.

[0021] Please see Figures 1-4 This utility model discloses a wire mesh tension meter calibration device, including a wire mesh tension meter calibration machine 1. Four pneumatic cylinders 2 are mounted on the outer surface of the wire mesh tension meter calibration machine 1. Each of the four pneumatic cylinders 2 has a power pulling component mounted on its outer surface. Each of the four power pulling components has a clamping pull plate 6 mounted on its outer surface. Each of the four clamping pull plates 6 has a spacing adjustment power component mounted on its top surface. A limit plate 13 is mounted on the outer surface of the spacing adjustment power component. A first limit slide rail 16 is mounted on the outer surface of the clamping pull plate 6. A first limit slider 17 is movably mounted on the outer surface of the first limit slide rail 16. One end of the first limit slider 17 is fixedly connected to one end of the limit plate 13. Limit grooves 14 are evenly distributed inside the limit plate 13. A synchronous movement adjustment component is mounted on the outer surface of the wire mesh tension meter calibration machine 1, thereby causing the limit post 15 to drive the electric telescopic rod 20 and... The second limiting slider 19 moves stably on the second limiting slide rail 18, thereby adjusting the spacing between several electric telescopic rods 20 so that the position of the rubber pressure head 4 on the outside of the electric telescopic rod 20 is the same as the distance to the wire mesh measurement point. When the electric telescopic rod 20 is working, it drives several rubber pressure heads 4 to fix the wire mesh measurement point. The rubber pressure head 4 can be accurately positioned on the wire mesh measurement point, ensuring that each measurement point receives a consistent fixing force, which helps to reduce measurement errors and improve the accuracy and reliability of calibration. The uniform pressure distribution helps to maintain the flatness and tension uniformity of the wire mesh. The rubber pressure head 4 is made of soft material, which can reduce damage to the wire mesh surface. The spacing between the electric telescopic rod 20 and the rubber pressure head 4 can be flexibly adjusted according to the specifications of the wire mesh and the position of the measurement point, which can be applied to different types and sizes of wire mesh, improving the versatility and flexibility of the equipment.

[0022] The power-pull assembly includes a pneumatic rod 5 and a tensioner 3. The pneumatic rod 5 is movably installed inside the pneumatic cylinder 2, and the tensioner 3 is installed on the outer surface of the pneumatic cylinder 2. One end of the pneumatic rod 5 is fixedly connected to one end of the clamping plate 6. The wire mesh tension gauge calibration machine 1 has four moving slots 8 inside, and moving blocks 7 are movably installed on the inner walls of the four moving slots 8. One end of the moving block 7 is in contact with one end of the clamping plate 6. The power-pull assembly includes a motor 9 and a ball screw 10. The motor 9 is installed on the outer surface of the clamping plate 6, and the ball screw 10 is installed on the outer surface of the clamping plate 6. On the outer surface of the output end of motor 9, a ball screw slider 11 is movably mounted on the outer surface of ball screw 10. A connecting plate 12 is mounted on the outer surface of the ball screw slider 11. The outer surface of the connecting plate 12 is fixedly connected to one end surface of the limiting plate 13. The synchronous movement adjustment assembly includes several second limiting sliders 19 and two second limiting slide rails 18. The two second limiting slide rails 18 are mounted on one end surface of the clamping pull plate 6. Several second limiting sliders 19 are movably mounted on the outer surfaces of both second limiting slide rails 18. The outer surfaces of the two second limiting sliders 19 share a common... An electric telescopic rod 20 is installed, and a limit post 15 is installed on the outer surface of several electric telescopic rods 20. The outer surface of the limit post 15 is in contact with the inner wall of the limit groove 14. A rubber pressure head 4 is installed on the outer surface of the electric telescopic rod 20. A through groove 21 is opened on the clamping plate 6. The plane of the clamping plate 6 is on the same horizontal plane as the plane of the wire mesh tension gauge calibration machine 1, which facilitates the flat placement of the wire mesh end face on the clamping plate 6, ensuring that the wire mesh is evenly stressed under tension and avoiding uneven tension distribution caused by unevenness. The flat surface facilitates observation and measurement, improving the accuracy and reliability of calibration. The flat end face of the wire mesh makes it easier for operators to place the wire mesh on the clamping plate 6 and quickly adjust it to the correct position. The horizontally placed wire mesh is less susceptible to additional twisting or damage during tension calibration, which helps maintain the integrity and service life of the wire mesh. The flat placement also reduces the risk of wire mesh wear and breakage caused by unevenness. When the end face of the wire mesh is on the same horizontal plane as the calibration machine, the relative position between the measurement points is more stable, which helps to obtain consistent measurement results.

[0023] The working principle and usage process of this utility model are as follows: When it is necessary to calibrate the wire mesh tension, the wire mesh is placed on the wire mesh tension meter calibration machine 1. The wire mesh tension meter calibration machine 1 consists of a horizontal X and a vertical Y structure of a Coragina frame, with a cross-shaped wire mesh fixed in the middle. The wire mesh tension is generated by applying tension in two directions through a pneumatic cylinder 2. The end face of the wire mesh is placed on the clamping plate 6. The plane of the clamping plate 6 is on the same horizontal plane as the plane of the wire mesh tension meter calibration machine 1, which facilitates the flat placement of the wire mesh end face on the clamping plate 6, ensuring that the wire mesh is evenly stressed under tension and avoiding unevenness. To address the issue of uneven tension distribution, the horizontally placed wire mesh end face facilitates observation and measurement, improving the accuracy and reliability of calibration. The flat end face also allows operators to more easily place the wire mesh on the clamping plate 6 and quickly adjust it to the correct position. The horizontally placed wire mesh is less susceptible to additional twisting or damage during tension calibration, helping to maintain its integrity and lifespan. The flat placement also reduces the risk of wire mesh wear and breakage due to unevenness. When the wire mesh end face and the calibration machine plane are on the same horizontal plane, the relative positions between measurement points are more stable, contributing to consistent measurement results.

[0024] The motor 9 operates by driving the ball screw 10 to rotate. The ball screw 10 and the screw slider 11 cooperate with each other, causing the screw slider 11 to move the limiting plate 13 via the connecting plate 12. The limiting plate 13 then moves the first limiting slider 17 on the first limiting slide rail 16, allowing the limiting plate 13 to move stably up and down. The limiting plate 13 stably moves several limiting grooves 14, and the inner wall of the limiting grooves 14 presses against the outer surface of the limiting post 15, causing the limiting post 15 to move the electric telescopic rod 20 and the second limiting slider 19 stably on the second limiting slide rail 18. This adjusts the spacing between the electric telescopic rods 20 so that the position of the rubber pressure head 4 on the outer side of the electric telescopic rod 20 is the same as the distance to the wire mesh measuring point. The rod 20 operates, driving several rubber pressure heads 4 to fix the wire mesh measurement points. The rubber pressure heads 4 can be accurately positioned on the wire mesh measurement points, ensuring that each measurement point receives a consistent fixing force, which helps reduce measurement errors and improve the accuracy and reliability of calibration. The uniform pressure distribution helps maintain the flatness and tension uniformity of the wire mesh. The rubber pressure heads 4 are made of soft materials, which can reduce damage to the wire mesh surface. The electric telescopic rod 20 and the rubber pressure heads 4 can be flexibly adjusted in spacing according to the specifications of the wire mesh and the position of the measurement points, making them suitable for different types and sizes of wire mesh, improving the versatility and flexibility of the equipment. Then, by applying air pressure, the air pressure rod 5 moves within the air pressure cylinder 2, thereby pulling the clamping pull plate 6 horizontally. The tension of the wire mesh is observed through the tension machine 3.
