Description

Technical Field

[0001] This invention relates to the field of cellulose acetate technology, and in particular to a portable rapid testing device for cellulose acetate products. Background Technology

[0002] Cellulose acetate is a semi-synthetic polymer material produced from cellulose through an acetic acid esterification reaction. It possesses excellent transparency, mechanical strength, biocompatibility, and biodegradability, and is widely used in textiles, plastics, membrane materials, pharmaceuticals, and many other fields. In actual production, cellulose acetate is often processed into sheet form for supply. Its quality directly affects the performance of downstream products; therefore, the testing of key indicators for cellulose acetate sheets is an indispensable part of the production process. These key testing indicators mainly include geometric dimensional parameters such as thickness, length, and width, as well as mechanical property parameters such as compressive strength. Whether these indicators meet the standards directly determines whether the finished product can meet the requirements of actual applications.

[0003] However, existing testing methods for cellulose acetate boards have many shortcomings: The testing process is cumbersome. Indicators such as thickness, length, width, and compressive strength need to be tested in stages using different testing tools or equipment. The operation steps are complex and require professional personnel to perform multiple steps. This not only consumes a lot of time and manpower, but also easily leads to human error due to too many testing steps, affecting the accuracy and consistency of the test data.

The portable cellulose acetate finished product rapid testing device of the present invention realizes the linkage between the length measuring component and the width measuring component through a synchronous moving component. When the length measuring component moves, the first connecting plate drives the traction column to slide in the guide groove, thereby pushing the rectangular plate and the second connecting plate to move, driving the width measuring component to move synchronously, ensuring the coordination and synchronization of the measurement process, and improving the consistency of the test data.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figures 1-7 Example 1: A portable rapid testing device for cellulose acetate finished products includes a testing platform 1. An electric push rod 2 is provided on the top of the testing platform 1, and an L-shaped lifting plate 3 is fixedly connected to the piston rod of the electric push rod 2. A pressure sensor 4 is installed at the bottom of the outer wall of one end of the L-shaped lifting plate 3. An installation sleeve 5 is provided on the bottom outer wall of the pressure sensor 4, and a pressure plate 6 for squeezing cellulose acetate sheets is provided on the bottom outer wall of the installation sleeve 5. A photoelectric thickness sensor 7 is installed inside the installation sleeve 5.

[0019] Through the above scheme, the electric push rod 2 serves as the power source, which can precisely control the lifting height of the L-shaped lifting plate 3, ensuring that the squeezing force of the pressure plate 6 on the cellulose acetate board is controllable. The pressure sensor 4 can collect pressure data in real time during the squeezing process, providing an accurate basis for judging the compressive strength of the board. The mounting sleeve 5 serves to fix the photoelectric thickness sensor 7, keeping it stable during the detection process and ensuring the accuracy of thickness detection. This achieves simultaneous detection of compressive strength and thickness indicators, eliminating the need for staged operations and improving detection efficiency.

[0020] In this embodiment, the L-shaped lifting plate 3 is driven to descend by the electric push rod 2, which in turn drives the pressure plate 6 to compress the cellulose acetate sheet. The pressure sensor 4 can detect the pressure value in real time during the compression process, so as to achieve accurate detection of the compressive strength of the sheet. At the same time, the photoelectric thickness sensor 7 inside the mounting sleeve 5 can detect the thickness of the sheet simultaneously. There is no need to use a separate detection tool, so as to achieve simultaneous detection of compressive strength and thickness indicators, reduce detection steps, and improve detection efficiency.

[0021] In embodiment 2, a connecting rod 8 is hinged to the bottom of the outer wall of the other end of the L-shaped lifting plate 3, and a transverse block 9 is hinged to the outer wall of one end of the connecting rod 8. A push-pull plate 10 is welded to the outer wall of one end of the transverse block 9, and a spring 11 is fixedly connected to the outer wall of one side of the push-pull plate 10. A length measuring component 12 is fixedly connected to the outer wall of one end of the spring 11, and a width measuring component 14 is provided on the outer wall of one side of the synchronous moving component 13.

[0022] Through the above scheme, the lifting motion of the L-shaped lifting plate 3 is converted into the horizontal movement of the transverse block 9 through the connecting rod 8, which in turn drives the push-pull plate 10 to move horizontally, providing power for the length measuring component 12 and the width measuring component 14, realizing the automatic feeding of the length measuring component 12 and the width measuring component 14 without manual pushing, reducing the intensity of manual operation. The elastic characteristics of the spring 11 can automatically adjust the clamping force, so that the first side clamping plate 122 and the second side clamping plate 142 can closely fit the plates of different sizes, while avoiding damage to the plates due to excessive clamping, thus improving the versatility and safety of the equipment.

[0023] The length measuring assembly 12 includes a first U-shaped plate 121, a first side clamping plate 122, and a photoelectric length measuring sensor 123. The first U-shaped plate 121 is fixedly connected to the outer wall of one end of the spring 11, the first side clamping plate 122 is welded to the outer wall of one side of the first U-shaped plate 121, and the photoelectric length measuring sensor 123 is fixedly connected to the top outer wall of the first side clamping plate 122 by screws.

[0024] Through the above scheme, the first U-shaped plate 121 provides a stable mounting base for the first side clamping plate 122 and the photoelectric length measuring sensor 123, ensuring the firmness of the component connection. The first side clamping plate 122 cooperates with the positioning plate 15 to achieve positioning and clamping of the plate in the length direction, so that the plate remains stable during the length measurement process. The photoelectric length measuring sensor 123, through cooperation with the length calibration plate 16, can quickly and accurately collect the plate length data. The screw connection method facilitates the installation, disassembly and maintenance of the photoelectric length measuring sensor 123, reducing equipment maintenance costs.

[0025] The width measuring assembly 14 includes a second U-shaped plate 141, a second side clamping plate 142, and a photoelectric width measuring sensor 143. The second U-shaped plate 141 is welded to one end of the outer wall of the second connecting plate 135, the second side clamping plate 142 is welded to one side of the outer wall of the second U-shaped plate 141, and the photoelectric width measuring sensor 143 is fixedly connected to the top outer wall of the second U-shaped plate 141 by screws.

[0026] Through the above scheme, the structural design of the second U-shaped plate 141 is adapted to the first U-shaped plate 121, ensuring the structural stability of the width measuring component 14. The second side clamping plate 142 cooperates with the positioning plate 15 to achieve positioning and clamping of the plate in the width direction, ensuring the stability of the plate during the width measurement process. The photoelectric width measuring sensor 143 corresponds to the width calibration plate 17, which can quickly and accurately collect the width data of the plate and work synchronously with the length measuring component 12 to achieve simultaneous detection of length and width dimensions, further improving the detection efficiency.

[0027] In this embodiment, when the L-shaped lifting plate 3 descends, it drives the transverse block 9 and the push-pull plate 10 to move via the connecting rod 8. The push-pull plate 10 pushes the length measuring component 12 to move via the spring 11, so that the first side clamping plate 122 fits against the side of the plate. With the help of the length calibration piece 16 on the positioning plate 15, the photoelectric length measuring sensor 123 can quickly and accurately measure the length of the plate. At the same time, the width measuring component 14 fits against the other side of the plate via the second side clamping plate 142. With the help of the width calibration piece 17, the photoelectric width measuring sensor 143 completes the width detection, realizing the synchronous detection of length and width indicators, further simplifying the detection process. Moreover, the spring 11 can play a buffering role, avoiding excessive clamping force that could damage the plate and ensuring the integrity of the plate during the detection process.

[0028] In embodiment 3, a synchronous moving component 13 is provided on one side of the outer wall of the length measuring component 12. The synchronous moving component 13 includes a first connecting plate 131, a traction column 132, a rectangular plate 133, a guide groove 134, and a second connecting plate 135. The first connecting plate 131 is welded to one side of the outer wall of the first U-shaped plate 121, the traction column 132 is welded to one end of the outer wall of the first connecting plate 131, the rectangular plate 133 is disposed above the first connecting plate 131, the guide groove 134 is opened on the top outer wall of the rectangular plate 133, and the traction column 132 slides in cooperation with the guide groove 134. The second connecting plate 135 is welded to one side of the outer wall of the rectangular plate 133.

[0029] Through the above scheme, the first connecting plate 131 realizes the fixed connection between the length measuring component 12 and the traction column 132, ensuring the stability of power transmission. The sliding cooperation between the traction column 132 and the guide groove 134 converts the horizontal movement of the length measuring component 12 into the horizontal movement of the rectangular plate 133. Then, the second connecting plate 135 drives the width measuring component 14 to move synchronously, realizing the linkage control of the length measuring component 12 and the width measuring component 14, ensuring the coordination of their movements, avoiding motion interference, and improving the stability and reliability of equipment operation. The design of the guide groove 134 provides a stable movement trajectory for the traction column 132, ensuring the accuracy of power transmission.

[0030] In this embodiment, the linkage between the length measuring component 12 and the width measuring component 14 is realized by the synchronous moving component 13. When the length measuring component 12 moves, the first connecting plate 131 drives the traction column 132 to slide in the guide groove 134, thereby pushing the rectangular plate 133 and the second connecting plate 135 to move, driving the width measuring component 14 to move synchronously, ensuring the coordination and synchronization of the measurement process, and improving the consistency of the detection data.

[0031] A positioning plate 15 for positioning cellulose acetate sheets is welded to the outer edge of the top of the testing table 1. Length calibration plates 16 and width calibration plates 17 are respectively installed on the inner walls of both sides of the positioning plate 15. The length calibration plates 16 and width calibration plates 17 correspond to the photoelectric length measuring sensor 123 and the photoelectric width measuring sensor 143, respectively.

[0032] Through the above scheme, the positioning plate 15 provides a positioning reference for the cellulose acetate board, ensuring that the board is placed accurately during the testing process and avoiding deviations in the test data due to board displacement. The length calibration plate 16 provides a measurement reference for the photoelectric length sensor 123, and the width calibration plate 17 provides a measurement reference for the photoelectric width sensor 143. The accuracy of the measurement data is ensured through reference calibration. The welding method makes the positioning plate 15 firmly connected to the testing table 1, improving the load-bearing capacity and stability of the positioning plate 15 and ensuring the positioning accuracy during long-term use.

[0033] The top outer wall of the testing platform 1 has a material discharge port 19 located below the cellulose acetate board, and the bottom outer wall of the testing platform 1 has a corner plate 18 welded to the bottom side of the material discharge port 19. The outer walls on both sides of the corner plate 18 are respectively fixedly connected to the first guide rod 21 and the second guide rod 22. The push-pull plate 10 and the first U-shaped plate 121 are installed through the outer wall of the first guide rod 21, and the second U-shaped plate 141 is installed through the outer wall of the second guide rod 22.

[0034] Through the above scheme, the material discharge port 19 facilitates the rapid unloading of the plate after the inspection is completed, improving the continuity of the inspection process. The corner plate 18 provides stable installation support for the first guide rod 21 and the second guide rod 22. The first guide rod 21 guides the movement of the push-pull plate 10 and the first U-shaped plate 121, and the second guide rod 22 guides the movement of the second U-shaped plate 141, ensuring the accuracy of the movement trajectory of each component, avoiding deviation or jamming during the movement, and improving the smoothness of equipment operation.

[0035] A top frame 20 is welded to the top outer wall of the positioning plate 15, and the electric push rod 2 is fixedly connected to the top outer wall of the top frame 20 by screws. A side plate 24 is welded to one side outer wall of the top frame 20, and a data display screen 25 is installed on one side outer wall of the side plate 24. A start / stop switch 26 is provided on one side of the data display screen 25, and a PLC controller 27 is installed on the top outer wall of the top frame 20. The PLC controller 27 is connected to the electric push rod 2, pressure sensor 4, photoelectric thickness sensor 7, photoelectric length sensor 123, photoelectric width sensor 143, and data display screen 25 through signal lines.

[0036] Through the above scheme, the top frame 20 not only provides an installation position for the electric push rod 2, but also provides an installation carrier for the side plate 24 and the PLC controller 27, making the equipment structure layout more reasonable and compact. The side plate 24 provides installation space for the data display screen 25 and the start / stop switch 26. The data display screen 25 can display the detection data in real time, which is convenient for operators to view intuitively. The start / stop switch 26 makes it easy for operators to control the start and stop of the equipment, and the operation is simple and convenient. As the control core of the equipment, the PLC controller 27 can receive the detection data of each sensor and control the operation of the electric push rod 2 to realize the automated control of the equipment. The signal line connection ensures the timeliness and accuracy of data transmission and instruction transmission, improving the automation level and detection efficiency of the equipment.

[0037] The top outer wall of the testing table 1 is provided with a sliding groove 23, and the first U-shaped plate 121 and the second U-shaped plate 141 are slidably connected to the inner wall of the sliding groove 23.

[0038] Through the above scheme, the slide 23 provides guidance and limit for the sliding of the first U-shaped plate 121 and the second U-shaped plate 141, ensuring that the two move smoothly in the horizontal direction and avoiding tilting or deviation, thereby further ensuring the motion accuracy of the length measuring component 12 and the width measuring component 14.

[0039] Support legs 28 are welded to the four corners of the bottom outer wall of the testing table 1, and lockable casters 29 are installed at the four corners of the bottom outer wall of the support legs 28.

[0040] Through the above solution, the support leg 28 provides stable support for the testing table 1, ensuring the levelness and stability of the equipment when it is placed, and avoiding the impact of equipment shaking on the testing accuracy. The lockable casters 29 enable the equipment to move flexibly, allowing operators to easily move the equipment to the required testing position, meeting the needs of different scenarios such as on-site testing and multi-station testing.

[0041] Working principle: First, the equipment is moved to the required testing position using the casters 29 at the bottom of the support legs 28. The casters 29 are then locked to secure the equipment and ensure stability during testing. The cellulose acetate sheet to be tested is placed on top of the testing table 1, with one side of the sheet aligned with the positioning plate 15, completing the initial positioning of the sheet. The operator starts the equipment using the start / stop switch 26 on the side plate 24. After receiving the start signal, the PLC controller 27 controls the electric push rod 2 on the top frame 20 to start. The piston rod of the electric push rod 2 extends, pushing the L-shaped lifting plate 3 downward.

[0042] One end of the L-shaped lifting plate 3 drives the pressure sensor 4, mounting sleeve 5, and pressure plate 6 to descend synchronously. The pressure plate 6 gradually contacts and squeezes the cellulose acetate sheet. The pressure sensor 4 collects the pressure data in real time during the squeezing process. At the same time, the photoelectric thickness sensor 7 inside the mounting sleeve 5 detects the thickness data of the sheet. The detection data of both are transmitted to the PLC controller 27 through the signal line. Meanwhile, the other end of the L-shaped lifting plate 3 drives the horizontal moving block 9 to move horizontally through the connecting rod 8. The horizontal moving block 9 pushes the push-pull plate 10 to slide along the first guide rod 21. The push-pull plate 10 pushes the first U-shaped plate 121 of the length measuring component 12 to move along the slide groove 23 and the first guide rod 21 through the spring 11, so that the first side clamp 122 fits against the other side of the length direction of the sheet. It cooperates with the positioning plate 15 to realize the positioning of the sheet in the length direction. At this time, the photoelectric length sensor 123 cooperates with the length calibration piece 16 on the positioning plate 15 to collect the sheet length data and transmit it to the PLC controller 27. During the movement of the length measuring component 12, the first connecting plate 131 on the first U-shaped plate 121 drives the traction column 132 to move. The traction column 132 slides in the guide groove 134 of the rectangular plate 133, pushing the rectangular plate 133 to move. The rectangular plate 133 drives the second U-shaped plate 141 of the width measuring component 14 to move along the slide groove 23 and the second guide rod 22 through the second connecting plate 135, so that the second side clamping plate 142 fits against the other side of the width direction of the plate, and cooperates with the positioning plate 15 to realize the positioning of the plate width direction. The photoelectric width sensor 143 cooperates with the width calibration piece 17 on the positioning plate 15 to collect the plate width data and transmit it to the PLC controller 27. After processing the received data on pressure resistance, thickness, length, and width, the PLC controller 27 transmits the data to the data display screen 25 for real-time display, allowing operators to view the test results. After the test is completed, the PLC controller 27 controls the piston rod of the electric push rod 2 to retract, causing the L-shaped lifting plate 3 to rise and the pressure plate 6 to detach from the plate. At the same time, the L-shaped lifting plate 3 drives the transverse block 9 and the push-pull plate 10 to move in the opposite direction through the connecting rod 8, and the spring 11 resets. The length measuring component 12 and the width measuring component 14 move in the opposite direction and reset under the tension of the spring 11, releasing the plate.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
