Description

Technical Field

[0001] This utility model relates to the field of fluoropolymer-coated roller testing technology, and in particular to a fluoropolymer-coated roller deformation testing device. Background Technology

[0002] As a core component of the fixing unit in printers and copiers, the deformation of the fluoropolymer-coated roller directly affects the operational stability and output quality of the equipment.

[0003] Regarding technologies related to the deformation of fluoropolymer-coated rollers, such as the fixing roller anti-deformation mechanism disclosed in patent number CN219456733U, which prevents deformation by accelerating the cooling speed; however, no technology related to the measurement of deformation of fluoropolymer-coated rollers is disclosed. This utility model is designed and manufactured to measure the deformation of fluoropolymer-coated rollers of different sizes and materials. Utility Model Content

[0004] The purpose of this utility model is to provide a fluoropolymer-coated roller deformation testing device, which solves the problem that there is no equipment in the prior art to detect the deformation of fluoropolymer-coated rollers.

[0005] This utility model is implemented as follows: a fluoropolymer-coated roller deformation testing device includes a base support module, a pressure supply module, and a data measurement module arranged sequentially from bottom to top. The base support module is used to place a rotatable fluoropolymer-coated roller, the pressure supply module is used to provide pressure to the fluoropolymer-coated roller, and the data measurement module is used to detect changes in the data of the pressure supply module.

[0006] The pressure supply module includes a support rod base, a pressure component, and a counterweight. The pressure component is installed below the support rod base via a pressure component bracket for extrusion contact with the fluoropolymer coating roller. The counterweight is detachably installed above the support rod base. Both ends of the support rod base are slidably connected to the base support module via guide components.

[0007] The testing device also includes a pressure sensor for detecting the pressure between the fluoropolymer-coated roller and the pressure component.

[0008] In this invention, the fluoropolymer-coated roller to be tested is rotatably placed on the base support module to limit its movement and prevent horizontal movement during the testing process. Then, the pressure supply module is placed above the base support module, with the entire weight of the pressure supply module pressing on the fluoropolymer-coated roller. A counterweight is selected based on the pressure display on the pressure sensor to ensure that the pressure value provided by the pressure supply module is essentially consistent with the pressure value of the fluoropolymer-coated roller in the actual use environment or a standard pressure value, thus guaranteeing the accuracy of the test results. Finally, the data measurement module is installed above the pressure supply module, with its detection end in contact with the surface of the pressure supply module. The data changes on the pressure supply module are observed within a set time. Based on these data changes, the deformation of the fluoropolymer-coated roller can be determined. The data changes of the fluoropolymer-coated roller under this pressure are compared with the data of a standard or qualified product to determine whether the fluoropolymer-coated roller is qualified.

[0009] A further technical solution of this utility model is: the base frame is provided with handling handles at both ends, and the entire testing device can be moved to an environment with a set temperature and humidity through the handling handles to conduct simulation experiments.

[0010] A further technical solution of this utility model is: the pressure component includes a curved pressure roller and a flat pressure block, the curved pressure roller is placed between the pressure component supports and is rotatably connected to the pressure component supports, and the flat pressure block is detachably connected to the lower part of the pressure component supports.

[0011] In the national standard, there are two methods for measuring the deformation of fluoropolymer-coated rollers: curved surface static pressure and planar static pressure. Curved surface static pressure measurement involves placing a planar pressure block above the pressure supply module, which then contacts the fluoropolymer-coated roller under its own weight. Specifically, the curved pressure roller within the pressure supply module contacts the fluoropolymer-coated roller. Planar static pressure measurement involves moving the planar pressure block, originally placed above the pressure supply module, below the curved pressure roller. A ring magnet then strongly attracts the planar pressure block to the pressure component support, bringing it into contact with the fluoropolymer-coated roller. This invention can achieve both static pressure measurements. Since the shape of the pressing surface of the fluoropolymer-coated roller changes, this invention allows for data testing of two states on a single pressure supply module, and can be operated by a single person.

[0012] A further technical solution of this utility model is: the end of the curved pressure roller is provided with a rotating component for driving the curved pressure roller to rotate.

[0013] Rotating the rotating component can drive the curved pressure roller to rotate. During the rotation of the curved pressure roller, a flexible pressure sensor can be introduced between the curved pressure roller and the fluoropolymer-coated roller. The pressure sensor measures the pressure supplied to the fluoropolymer-coated roller by the pressure supply module. By selecting different counterweights, the pressure value of the pressure sensor can be made to have an error of less than 3% with the pressure value of the fluoropolymer-coated roller in actual application.

[0014] A further technical solution of this utility model is: the pressure sensor is a flexible pressure sensor, and the curved pressure roller or fluoropolymer-coated roller rotates to bring the flexible pressure sensor between the pressure component and the fluoropolymer-coated roller.

[0015] By employing a flexible pressure sensor, the sensor is brought into contact with the curved pressure roller or the fluoropolymer-coated roller through the rotation of the curved pressure roller or the fluoropolymer-coated roller, or between the flat pressure block and the fluoropolymer-coated roller, thus making the detection of the pressure on the fluoropolymer-coated roller more accurate.

[0016] A further technical solution of this utility model is: the support rod base is provided with a rectangular groove for placing a planar pressure block.

[0017] In the national standard, the deformation of fluoropolymer-coated rollers can be measured in two ways: curved surface static pressure and flat surface static pressure. A rectangular groove is provided on the support rod base. When performing curved surface static pressure testing, the flat surface pressure block is placed in the rectangular groove. When performing flat surface static pressure testing, the flat surface pressure block is installed below the curved surface pressure roller and in contact with the fluoropolymer-coated roller. This ensures that one pressure supply module of this utility model can meet the data testing requirements of both states. Moreover, it can be operated by a single person.

[0018] A further technical solution of this utility model is: a foldable support rod assembly is provided between the base support module and the pressure supply module, and the support rod assembly can suspend the pressure component through the support rod base.

[0019] When the testing device in this utility model is idle, the support rod base is supported by the support rod assembly, so that the pressure component is suspended in the air, reducing the probability of mutual collision deformation or damage. The support rod assembly is very convenient and quick in actual use, and can also quickly change the product to be tested and adjust the efficiency of arc surface pressing test or plane pressing test.

[0020] A further technical solution of this utility model is: the support rod assembly includes a support rod and a support rod storage bracket, the support rod storage bracket can slide along the side of the support rod base, the support rod storage bracket is provided with a square magnet, and the support rod is rotatably disposed on the side of the support rod base and magnetically connected to the square magnet.

[0021] When the pressure supply module provides pressure to the fluoropolymer-coated roller, the support rod is connected to the support rod storage bracket via a square magnet. At this time, the support rod is fixed to the side of the support rod base, and the entire pressure supply module presses against the fluoropolymer-coated roller. When the pressure supply module is not needed to provide pressure to the fluoropolymer-coated roller, such as when the testing device is idle, the support rod storage bracket slides along the support rod base, causing the square magnet on the support rod storage bracket to disengage from the support rod or reduce the magnetic attraction. Then, the support rod is rotated to adjust it to a vertical position and limit it with the base support module, and the entire pressure supply module is suspended in the air.

[0022] A further technical solution of this utility model is: the base support module is provided with a support rod limiting bracket, and the support rod limiting bracket is provided with a U-shaped storage groove for limiting the support rod.

[0023] When the pressure supply module is not required to provide pressure, the support rod is rotated vertically and inserted into the U-shaped storage groove, thereby suspending the pressure supply module.

[0024] A further technical solution of this utility model is: the support rod limiting bracket is placed above both ends of the base frame, and the support rod limiting bracket is provided with a U-shaped storage groove to restrict the horizontal movement of the support rod, and the bottom of the support rod is supported and limited by the base frame.

[0025] A further technical solution of this utility model is: the base support module includes a base frame, a fluoropolymer coating roller bracket and a scale. The fluoropolymer coating roller bracket is used to install the fluoropolymer coating roller. The scale extends along the length direction of the base frame and the center of the scale is consistent with the center position of the base frame. The fluoropolymer coating roller bracket can slide along the length direction of the base frame to adjust the position of the fluoropolymer coating roller.

[0026] The main purpose of centering the scale in this invention is to facilitate the adjustment of the fluoropolymer-coated roller's position on the testing device. Since fluoropolymer-coated rollers have concave or convex characteristics, meaning that the outer diameters at both ends of the roller are basically the same but larger or smaller than the outer diameter of the middle part, the scale can be adjusted after installing the scale to center the roller in the required experimental position. This makes the data in the static pressure test more accurate and more meaningful for comparison.

[0027] A further technical solution of this utility model is: the data measurement module is symmetrically arranged at both ends of the pressure supply module, the data measurement module includes a clamp and a dial indicator, the dial indicator is mounted on the clamp, and the clamp and the guide are connected by a cap bolt.

[0028] After assembling the dial indicator and fixture, fix them to the guide component using cap bolts. During operation, bring the dial indicator head to zero after contacting the counterweight. After 72 hours of static pressure, read the deformation data and compare it with the deformation data of qualified products under the same conditions to determine whether the fluoropolymer coated roller is qualified. To further determine the qualification of the fluoropolymer coated roller, observe the change in the outer diameter rebound of the fluoropolymer coated roller at different time periods using a laser tester after obtaining the deformation data. Then compare it with the standard data to analyze the resilience of the fluoropolymer coated roller. If the rebound effect of the fluoropolymer coated roller is poor, there will be a problem of insufficient lifespan when using our printer and copier. The pressure between the deformed surface and the mating parts in the printer and copier will decrease, resulting in a shorter contact surface width between the fluoropolymer coated roller and the mating parts, which will affect its fixing effect.

[0029] A further technical solution of this utility model is: the guide member is placed at the end of the base frame, and the support rod base is provided with a linear bearing that is slidably connected to the guide member.

[0030] This invention is designed and manufactured to measure the deformation of fluoropolymer-coated rollers of different sizes and materials. It is based on the three elements of fixing in the document, printer, and copier industries, as specified in GB / T 7759-1996, which defines the determination of compression set of vulcanized rubber and thermoplastic rubber at room temperature, high temperature, and low temperature. This invention can measure the deformation data of fluoropolymer-coated rollers of different sizes and materials under different temperatures and humidity conditions, and then compare it with standard data to determine whether the produced fluoropolymer-coated rollers meet the usage requirements.

[0031] The beneficial effects of this utility model are as follows: In this utility model, the fluoropolymer-coated roller to be tested is rotatably placed on the base support module to limit its movement and prevent horizontal movement during the testing process. Then, the pressure supply module is placed above the base support module, with the entire weight of the pressure supply module pressing on the fluoropolymer-coated roller. A counterweight is selected based on the pressure display on the pressure sensor to ensure that the pressure value provided by the pressure supply module is basically consistent with the pressure value of the fluoropolymer-coated roller in the actual use environment or the standard, thus ensuring the accuracy of the test results. Finally, the data measurement module is installed above the pressure supply module, with the detection end of the data detection module in contact with the surface of the pressure supply module. The data changes of the data detection module on the pressure supply module are observed within a set time. Based on the data changes of the data detection module, the deformation of the fluoropolymer-coated roller can be determined. The data changes of the fluoropolymer-coated roller under this pressure are compared with the data of the standard or qualified product to determine whether the fluoropolymer-coated roller is qualified.

[0032] In the national standard, there are two methods for measuring the deformation of fluoropolymer-coated rollers: curved surface static pressure and planar static pressure. Curved surface static pressure measurement involves placing a planar pressure block above the pressure supply module, which then contacts the fluoropolymer-coated roller under its own weight. Specifically, the curved pressure roller within the pressure supply module contacts the fluoropolymer-coated roller. Planar static pressure measurement involves moving the planar pressure block, originally placed above the pressure supply module, below the curved pressure roller. A ring magnet then strongly attracts the planar pressure block to the pressure component support, bringing it into contact with the fluoropolymer-coated roller. This invention can achieve two types of static pressure measurements. Since the shape of the pressing surface of the fluoropolymer-coated roller changes, this invention allows for data testing of two states on a single pressure supply module, and can be operated by a single person.

[0033] This invention has the ability to measure the shape changes of fluoropolymer-coated rollers of all roller diameters (length, outer diameter) in existing printers and copiers, as well as the shape changes of fluoropolymer-coated rollers of all materials (solid foam, liquid silicone, and water foam). It has a wide range of applications, is lightweight and easy to transport, and can be transported to environments with different temperatures and humidity for experiments. It is simple and convenient to operate and has high accuracy.

[0034] In this invention, the base support module, by adding a scale, can adjust the accurate position of the slider to center the entire product, resulting in more accurate static pressure test data. The pressure supply module in this invention achieves a dual-purpose tooling effect, satisfying both the required arc-shaped static pressure and planar static pressure requirements. Furthermore, the support rod adjustment structure is simple, the strong magnetic attraction is stable and reliable, and the entire support rod structure effectively improves the service life of the tooling and enables convenient single-person experiments.

[0050] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0051] Example 1:

[0052] like Figure 1 As shown, this utility model consists of three modules: a base support module, a pressure supply module, and a data measurement module. This utility model is applicable to the printer and copier industries, providing strong support for measuring the deformation data of fluoropolymer-coated rollers of different sizes and materials.

[0053] In this embodiment, the first module is a base support module, which comprises a base frame 1, a scale 2, a slide rail 3, two sliders 4, two fluoropolymer-coated roller supports 5, six feet 6, two support rod limiting supports 7, four guides 8, two locking nuts 9, and two handling handles 10. Figure 2-4 .

[0054] In this embodiment, the guide member 8 is cylindrical.

[0055] In this embodiment, the second module is a pressure supply module, which comprises one support rod shaft 11, one rotating component 12, two annular magnets 13, four square magnets 14, one curved pressure roller 15, four support rod storage brackets 16, eight bolts 17, four support rods 18, two pressure component brackets 19, two pressure component bracket bearings 20, four support rod shaft fixing brackets 21, two handles A 22, two handles B 23, one planar pressure block 24, four linear bearings 25, and two adjusting handles 26. (See attached diagram) Figure 5-6 .

[0056] In this embodiment, the third module is a data measurement module, which consists of four capped bolts 27, two clamps 28, and two dial indicators 29. See [link / reference]. Figure 11 .

[0057] Figure 2-3 The diagram shows the base support module. Four guide members 8 are inserted into the four round holes of the base frame 1 and secured with bolts. Then, six feet 6 are inserted into the base frame 1 sequentially from bottom to top. Two handling handles 10 are placed on the two outermost feet 6 and secured with bolts. Next, two support rod limiting brackets 7 on both sides are secured to both ends of the base frame 1 with bolts. Then, a scale 2 is attached to the center of the side of the base frame 1. Two slide rails 3 are secured to the base frame 1 with bolts. Finally, two sliders 4, two fluoropolymer-coated roller brackets 5, and two locking bolts 9 are installed sequentially. The sliders 4 are slidably connected to the slide rails 3. The fluoropolymer-coated roller brackets 5 are fixed to the sliders 4. After the sliders 4 slide into position, they are limited by the locking bolts 9.

[0058] Figure 4The image shows the fluoropolymer-coated roller 30, whose deformation data is to be tested, placed on the base support module. The purpose of widening both the slide rail 3 and the slider 4 is to increase the overall compressive strength and stability of the equipment, avoiding situations where the slide rail is too small, leading to insufficient overall tooling life. The scale 2 is centered, with the "0" mark on the scale 2 at the center of the length of the base frame 1. This is primarily to ensure the fluoropolymer-coated roller 30 is placed more centrally on the tooling, as the fluoropolymer-coated roller 30 has either a concave or convex shape. The concave or convex shape refers to the outer diameter of the two ends of the fluoropolymer-coated roller 30 being approximately... The diameters are consistent, but all are greater than or less than the outer diameter of the middle part. Therefore, after installing the scale ruler 2, the scale position of the slider 4 can be adjusted to make the fluoropolymer-coated roller 30 centered in the required experimental position, so that the data in the static pressure test is more accurate and more meaningful for comparison. The locking nut 9 on our slider 4 can stabilize the slider 4 in the specified position and prevent it from shifting during the experiment. At the same time, the travel of the slide rail 3 in this utility model can be compatible with the deformation test of all fluoropolymer-coated roller 30 with A3 size and below on the market, and has wide compatibility.

[0059] Figure 5-6 The pressure supply module is shown. First, four linear bearings 25 are installed into the support rod base 32 and secured with bolts. Then, two handles A22 and two handles B23 are assembled with two support rod shafts 11. After completion, they are fixed in the reserved groove at the end of the support rod base 32. Four support rod fixing brackets 21 are used to limit the support rod shafts 11 on the support rod base 32. Rotating handle B23 can drive the support rod shafts 11 to rotate, thereby allowing the support rods 18 to rotate. Then, two adjusting handles 26 are installed on the support rod base 32, and the four support rod storage brackets 1 are sequentially installed. 6. Install the support rod base 32 on the front and rear sides and fix it with 8 bolts 17. Then install 2 bearings 20 and 2 ring magnets on the sides and bottom of the 2 pressure component brackets 19 respectively. Insert the curved pressure roller 15 with 1 rotating component 12 installed into the bearings 20 on both sides. Lock the pressure component bracket 19 to the support rod base 32 with bolts. Finally, place the flat pressure block 24 on the pressure component bracket 19 along the rectangular groove of the support rod base 32 for later use. During operation, different counterweights 31 can be selected according to the required pressure to achieve the static pressure environment required for different types of fluoropolymer coated rollers.

[0060] Figure 7 The image shows the effect after assembling the base support module and the pressure supply module. In this state, the curved pressure roller 15 is in contact with the fluoropolymer-coated roller 30 to be tested.

[0061] Figure 8The specific method of applying pressure is as follows: First, a flexible pressure sensor 33 is used to measure the working pressure of the fluoropolymer coated roller 30 in the printer or copier. Then, the fluoropolymer coated roller 30 is placed in the center on the fluoropolymer coated roller bracket 5. The curved pressure roller 15 is rotated by the rotating component 12. Under the action of friction, the fluoropolymer coated roller 30 to be tested will rotate accordingly. At this time, the flexible pressure sensor 33 is placed in the center between the fluoropolymer coated roller 30 and the curved pressure roller 15, so that the flexible pressure sensor 33 is inserted between the curved pressure roller 15 and the fluoropolymer coated roller 30. At this time, the pressure value must be small. By adding counterweights 31 of different weights, the error between the measured value on the pressure sensor 33 and the pressure value of the fluoropolymer coated roller 30 in the environment where it is to be used is less than 3%.

[0062] Figure 9 As shown, the national standard specifies two methods for measuring the deformation of the fluoropolymer-coated roller 30: curved surface static pressure and planar static pressure. For curved surface static pressure measurement: a planar pressure block 24 is placed above the pressure supply module. At this time, the pressure supply module, under its own weight, contacts the fluoropolymer-coated roller 30. Specifically, the curved pressure roller 15 within the pressure supply module contacts the fluoropolymer-coated roller 30. A flexible pressure sensor 33 is placed between the fluoropolymer-coated roller 30 and the curved pressure roller 15. The flexible pressure sensor 33 is brought between the two by the rotation of either the curved pressure roller 15 or the fluoropolymer-coated roller 30, allowing the pressure on the fluoropolymer-coated roller 30 to be measured. A counterweight 31 ensures that the error between the measured value of the flexible pressure sensor 33 and the actual pressure value during use does not exceed 3%. Planar static pressure measurement: The planar pressure block 24, originally placed above the pressure supply module, is moved to below the curved pressure roller 15. The planar pressure block 24 is strongly attracted to the pressure component support 19 and contacts the fluoropolymer-coated roller 30 by the ring magnet 13. By rotating the fluoropolymer-coated roller 30, the flexible pressure sensor 33 is brought between the fluoropolymer-coated roller 30 and the planar pressure block 24 to measure the pressure on the fluoropolymer-coated roller 30. The counterweight 31 ensures that the error between the measured value of the flexible pressure sensor 33 and the actual pressure value during use does not exceed 3%. This utility model changes the shape of the pressing surface of the fluoropolymer-coated roller to be measured, so that this utility model can realize data testing of two states on one pressure supply module, and can be operated by a single person.

[0063] Figure 10 The diagram shows cross-sectional views of the two static pressure test processes. The left image shows the planar static pressure state, and the right image shows the curved surface static pressure state. The arrows point to the contact surface between the fluoropolymer-coated roller and the pressure component.

[0064] Figure 11The data measurement module is shown. Two dial indicators 29 and two clamps 28 are assembled and fixed with four cap bolts 27. During operation, the dial indicators 29 are zeroed after contacting the counterweight 31. After 72 hours of static pressure, the deformation data is read. This data can be used to measure the rebound change of the outer diameter of the fluoropolymer-coated roller at different time periods using a laser tester. The rebound of the fluoropolymer-coated roller 30 can then be compared with standard data. If the rebound effect of the fluoropolymer-coated roller is poor, there will be a problem of insufficient lifespan when using printers and copiers. The pressure between the deformation surface and the mating parts in the printer and copier will decrease, resulting in a shorter contact surface width between the fluoropolymer-coated roller and the mating parts, which will affect the fixing effect.

[0065] Figure 12 The experimental configuration of the curved pressure roller 15 and the static pressure fluoropolymer-coated roller 30 is shown.

[0066] Figure 13 The figure shows the experimental configuration of the planar pressure block 24 static pressure fluoropolymer-coated roller 30.

[0067] Figure 14 The diagram shows the tooling in its idle state. First, push the support rod storage bracket 16 towards the center. After pushing, the magnetic attraction between the square magnet 14 and the support rod 18 will decrease. Then, by holding the adjustment handle 26 and moving the handle B23 with your fingers, the two support rod shafts 11 will drive the four support rods 18, adjusting the support rods 18 to a state perpendicular to the support rod limiting bracket 7 and locking them into the support rod limiting bracket 7. Finally, slide the two sliders 5 to both sides and abut against the support rod limiting bracket 7, and then lock them in place with the locking nut 9. In this way, the entire tooling will be in an idle state, with all key components suspended in the air, reducing the probability of mutual collision deformation or damage. This structural feature is very convenient and quick in actual use, and can also quickly change the product to be tested and adjust the efficiency of arc surface pressing experiments or flat surface pressing experiments.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
