Description

Technical Field

[0001] This application relates to the technical field of paper tube quality testing equipment, and in particular to a pressure-resistant paper tube quality testing equipment. Background Technology

[0002] Compression-resistant paper tubes are made of paper that absorbs liquid resin. After the resin solidifies, the surface of the paper tube has a high degree of smoothness. Compression-resistant paper tubes are paper products with excellent structural performance. They are used to wind aluminum foil, metal wire, and other materials. Therefore, the paper tubes are subjected to significant pressure after being wound into rolls, making them prone to deformation during lifting. Deformed paper tubes are susceptible to deformation or wrinkling, metal wires are prone to breakage, and metal foil may develop unevenness, resulting in economic losses. Therefore, all finished paper tubes undergo compression testing at the factory to determine product quality.

[0003] Regarding the aforementioned technologies, it has been found that traditional compressive strength paper tube quality testing equipment lacks effective limiting when testing the compressive strength of paper tubes. In addition, most of them use a single pressure plate to directly press the paper tube for testing. This makes it easy for the paper tube to deviate during the pressing process, resulting in a large error in the test results and failing to accurately reflect the true compressive strength of the paper tube. Utility Model Content

[0004] In order to achieve stable pressure testing of paper tubes, this application provides a pressure-resistant paper tube quality testing device.

[0005] The compressive strength paper tube quality testing device provided in this application adopts the following technical solution:

[0006] A pressure-resistant paper tube quality testing device includes a testing platform. A hanger is vertically mounted on the upper surface of the testing platform, and a testing cylinder is vertically fixed on the hanger. A testing seat is mounted on the output end of the testing cylinder. Bending arms are symmetrically mounted on both sides of the testing seat. The bending arms are slidably connected to the testing seat, and a driving component is installed in the testing seat to drive the two bending arms to move synchronously. A side pressure plate assembly is slidably mounted on the lower end of the bending arms, and a driving screw for extending and retracting the side pressure plate assembly is mounted on the bending arms. A vertical seat is also fixedly mounted in the middle of the lower surface of the testing seat, and an adjustable top pressure plate is mounted on the lower end of the vertical seat.

[0007] By adopting the above technical solution, the vertical compression resistance of paper tubes can be tested by moving the testing seat up and down with a testing cylinder. The symmetrical bending arms on both sides and the driving components that move them synchronously enable more stable pressure testing of the paper tubes, making it less prone to displacement during the testing process. The side pressure plate assembly can extend and retract at the lower end of the bending arms, facilitating further adjustment of the pressure position and magnitude on the sides of the paper tubes. The adjustable top pressure plate can be adjusted according to the height of different paper tubes and testing requirements, improving the flexibility and accuracy of the testing, and enabling comprehensive and accurate testing of the paper tubes' compression resistance.

[0008] Optionally, a horizontal plate is fixedly installed in the middle of the hanger, and two sets of guide tubes are symmetrically arranged on the lower end face of the horizontal plate, the guide tubes being integrally formed with the horizontal plate.

[0009] By adopting the above technical solution, the horizontal plate in the middle of the hanger and the one-piece molded guide tube provide a stable sliding track for the vertical slide bar. The guide tube enhances the structural stability of the hanger, making the detection seat move more smoothly during up and down movements, reducing swaying and offset, thereby ensuring the accuracy and reliability of the detection process.

[0010] Optionally, a vertical slide rod is slidably installed in the guide tube, and a connecting plate connected to the detection seat is provided at the lower end of the vertical slide rod. The connecting plate is fixedly connected to the vertical slide rod.

[0011] By adopting the above technical solution, the vertical slide bar slides in the guide tube and connects to the detection seat through the connecting plate, further improving the stability of the detection seat's vertical movement. The sliding engagement of the vertical slide bar effectively limits the movement trajectory of the detection seat, preventing it from tilting or shaking during movement, and ensuring the uniformity and accuracy of pressure application during the detection process.

[0012] Optionally, the detection seat includes a seat housing and a top seat connected to the output end of the detection cylinder. The top seat is installed at the center of the upper surface of the seat housing and is fixedly connected to the seat housing.

[0013] By adopting the above technical solution, the detection base uses a structure design of a base box and a top seat. The top seat is connected to the output end of the detection cylinder, and the base box is used to install other components. This structural design makes the installation and disassembly of the detection base more convenient, facilitating equipment maintenance and repair. At the same time, the base box can protect internal components such as drive parts, extending the service life of the equipment.

[0014] Optionally, the bending boom includes a frame housing and a threaded tube, the threaded tube being installed on the upper end face of the frame housing and integrally formed with the frame housing.

[0015] By adopting the above technical solution, the frame shell and the one-piece threaded tube structure of the bending boom make the bending boom structure more stable. The cooperation between the threaded tube and the drive component enables the smooth movement of the bending boom, ensuring the uniformity and stability of the pressure applied to both sides of the paper tube, and improving the accuracy of the test results.

[0016] Optionally, the driving component includes a plug-in housing and a double-ended screw. The double-ended screw is rotatably mounted in the plug-in housing, and a driven gear is fixedly sleeved in the middle of the double-ended screw. A driving gear that meshes with the driven gear is also rotatably mounted in the middle of the plug-in housing.

[0017] By adopting the above technical solution, the drive component employs a structural design consisting of a plug-in housing, a double-ended screw, a driven gear, and a drive gear. The drive gear rotates the driven gear, which in turn drives the double-ended screw, achieving synchronous movement of the bending booms on both sides. This transmission method features a simple structure, high transmission efficiency, and precise control over the moving distance and speed of the bending boom, ensuring the accuracy and repeatability of the testing process.

[0018] Optionally, the side pressure plate assembly includes a sliding plate and an inclined pressure plate. The sliding plate is slidably installed in the bending arm, and a threaded groove that mates with the drive screw is provided in the middle of the sliding plate. The inclined pressure plate is fixedly installed at the lower end of the sliding plate.

[0019] By adopting the above technical solution, the slide plate and inclined pressure plate structure of the side pressure plate assembly allow the slide plate to slide within the bending arm, achieving extension and retraction through threaded engagement with the drive screw. The inclined pressure plate design allows for better contact with the side of the paper tube, increasing the contact area and resulting in more uniform pressure application to the side of the paper tube, thus improving the accuracy of the test results.

[0020] Optionally, the adjustable top pressure plate includes a horizontal pressure plate and threaded vertical rods. The threaded vertical rods are evenly installed on the four corners of the upper surface of the horizontal pressure plate, and two sets of matching locking nuts are also installed on the threaded vertical rods.

[0021] By adopting the above technical solution, the adjustable top pressure plate, threaded vertical rod, and locking nut structure allow for easy adjustment of the horizontal pressure plate's height by adjusting the position of the locking nut on the threaded vertical rod, thus accommodating paper tubes of different heights. This adjustable design improves the equipment's versatility and can meet the testing requirements of paper tubes of different specifications.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The compression resistance paper tube quality testing equipment of this application can stably perform compression resistance testing on paper tubes, ensuring more accurate and reliable test results and providing a more comprehensive basis for paper tube quality assessment. The design of the guide tube, vertical slide bar, and other structures ensures the stability of the testing seat during vertical movement, reducing shaking and offset. Simultaneously, the rational design of the bending arm and drive components makes the pressure applied to both sides of the paper tube more uniform and stable, improving the accuracy and reliability of the testing process. The adjustable design of the top pressure plate and side pressure plate assembly allows the equipment to adapt to paper tubes of different specifications, improving the equipment's versatility and operational flexibility.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a device for testing the quality of compression-resistant paper tubes. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a paper tube compression resistance quality testing device includes a testing platform 1. A hanger 2 is vertically mounted on the upper surface of the testing platform 1. A testing cylinder 3 is vertically fixed on the hanger 2. A testing seat 4 is mounted on the output end of the testing cylinder 3. Bending arms 5 are symmetrically mounted on both sides of the testing seat 4. The bending arms 5 are slidably connected to the testing seat 4, and a driving component 6 is installed in the testing seat 4 to drive the bending arms 5 to move synchronously. A side pressure plate assembly 7 is slidably mounted on the lower end of the bending arms 5, and a driving screw 50 is mounted on the bending arms 5 to drive the side pressure plate assembly 7 to extend and retract. A vertical seat 40 is also fixedly mounted in the middle of the lower surface of the testing seat 4, and an adjustable top pressure plate 8 is mounted on the lower end of the vertical seat 40. By driving the testing seat 4 up and down with the testing cylinder 3, vertical compression resistance testing of the paper tube can be performed. The symmetrical bending arms 5 on both sides and the driving component 6 that drives them to move synchronously enable more stable pressure testing of the paper tube, making it less likely for the paper tube to deviate during the testing process. The side pressure plate assembly 7 can extend and retract at the lower end of the bending arm 5, facilitating further adjustment of the pressure position and magnitude on the side of the paper tube. The adjustable top pressure plate 8 can be adjusted according to the height of different paper tubes and testing requirements, improving the flexibility and accuracy of testing, and enabling comprehensive and accurate testing of the compressive strength of the paper tube.

[0031] Reference Figure 1 As shown, a horizontal plate 21 is fixedly installed in the middle of the hanger 2. Two sets of guide tubes 22 are symmetrically arranged on the lower end of the horizontal plate 21, and the guide tubes 22 are integrally formed with the horizontal plate 21. The horizontal plate 21 and the integrally formed guide tubes 22 in the middle of the hanger 2 provide a stable sliding track for the vertical slide rod 23. The setting of the guide tubes 22 enhances the structural stability of the hanger 2, making the detection seat 4 more stable during up and down movement, reducing shaking and offset, thereby ensuring the accuracy and reliability of the detection process. The vertical slide rod 23 is slidably installed in the guide tube 22, and the lower end of the vertical slide rod 23 is provided with a connecting plate 231 connected to the detection seat 4. The connecting plate 231 is fixedly connected to the vertical slide rod 23. The vertical slide rod 23 slides in the guide tube 22 and is connected to the detection seat 4 through the connecting plate 231, further improving the stability of the up and down movement of the detection seat 4. The sliding engagement of the vertical slide bar 23 can effectively limit the movement trajectory of the detection seat 4, prevent it from tilting or shaking during movement, and ensure the uniformity and accuracy of pressure application during the detection process.

[0032] Reference Figure 3 and Figure 4As shown, the detection base 4 includes a base housing 41 and a top seat 42 connected to the output end of the detection cylinder 3. The top seat 42 is installed at the center of the upper surface of the base housing 41 and is fixedly connected to the base housing 41. The detection base 4 adopts a structural design of base housing 41 and top seat 42. The top seat 42 is connected to the output end of the detection cylinder 3, and the base housing 41 is used to install other components. This structural design makes the installation and disassembly of the detection base 4 more convenient, facilitating equipment maintenance and repair. At the same time, the base housing 41 can protect internal components such as the drive unit 6, extending the service life of the equipment.

[0033] Reference Figure 2 As shown, the bending boom 5 includes a frame housing 51 and a threaded tube 52. The threaded tube 52 is installed on the upper end face of the frame housing 51 and is integrally formed with the frame housing 51. The frame housing 51 and the integrally formed threaded tube 52 structure of the bending boom 5 make the structure of the bending boom 5 more stable. The cooperation between the threaded tube 52 and the drive component 6 enables the smooth movement of the bending boom 5, ensuring the uniformity and stability of the pressure applied to both sides of the paper tube, and improving the accuracy of the test results.

[0034] Reference Figure 2 and Figure 5 As shown, the drive component 6 includes a plug-in housing 61 and a double-ended screw 62. The double-ended screw 62 is rotatably mounted in the plug-in housing 61, and a driven gear 621 is fixedly sleeved in the middle of the double-ended screw 62. A drive gear 611, meshing with the driven gear 621, is also rotatably mounted in the middle of the plug-in housing 61. The drive component 6 adopts a structural design of plug-in housing 61, double-ended screw 62, driven gear 621, and drive gear 611. The drive gear 611 drives the driven gear 621 to rotate, which in turn drives the double-ended screw 62 to rotate, realizing the synchronous movement of the two bending booms 5. This transmission method has a simple structure, high transmission efficiency, and can accurately control the moving distance and speed of the bending boom 5, ensuring the accuracy and repeatability of the detection process.

[0035] Reference Figure 3 As shown, the side pressure plate assembly 7 includes a sliding plate 71 and an inclined pressure plate 72. The sliding plate 71 is slidably mounted in the bending arm 5, and a threaded groove is provided in the middle of the sliding plate 71 to cooperate with the drive screw 50. The inclined pressure plate 72 is fixedly mounted on the lower end of the sliding plate 71. The sliding plate 71 slides in the bending arm 5 and extends and retracts through the threaded engagement with the drive screw 50. The design of the inclined pressure plate 72 allows for better contact with the side of the paper tube, increasing the contact area and resulting in more uniform pressure application to the side of the paper tube, thus improving the accuracy of the test results.

[0036] Reference Figure 3 and Figure 4As shown, the adjustable top pressure plate 8 includes a horizontal pressure plate 81 and threaded vertical rods 82. The threaded vertical rods 82 are evenly installed at the four corners of the upper surface of the horizontal pressure plate 81, and two sets of cooperating locking nuts 83 are also installed on the threaded vertical rods 82. The structural design of the horizontal pressure plate 81, threaded vertical rods 82, and locking nuts 83 in the adjustable top pressure plate 8 allows for easy adjustment of the height of the horizontal pressure plate 81 by adjusting the position of the locking nuts 83 on the threaded vertical rods 82, thus accommodating paper tubes of different heights. This adjustable design improves the versatility of the equipment and can meet the testing requirements of paper tubes of different specifications.

[0037] The implementation principle of the compression-resistant paper tube quality testing device in this application embodiment is as follows: During actual testing, the paper tube to be tested is placed on the testing table 1, positioned below the adjustable top pressure plate 8 and the side pressure plate group 7. The testing cylinder 3 is activated, causing the testing seat 4 to move downwards. The adjustable top pressure plate 8 gradually contacts the top of the paper tube, applying vertical pressure to the paper tube, and the deformation of the paper tube is observed. Simultaneously, according to the size of the paper tube, the drive gear 611 can be manually rotated to rotate the drive screw 50, further adjusting the distance between the two sides of the side pressure plate group 7. Furthermore, the height of the horizontal pressure plate 81 is changed by adjusting the position of the locking nut 83 on the threaded vertical rod 82, ensuring that the horizontal pressure plate 81 and the inclined pressure plate 72 can stably hold the paper tube to be tested. The deformation data of the paper tube under different pressures is recorded, and the compression resistance of the paper tube is evaluated based on these data.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
