Description

Technical Field

[0001] This utility model relates to the field of chemical fiber paper tube technology, and in particular to a testing machine for testing the toughness of chemical fiber paper tubes. Background Technology

[0002] Chemical fiber paper tubes (also known as industrial paper tubes) are widely used in textile, film, and packaging industries. As a winding mandrel for materials such as yarn and film, their toughness (resistance to compression, bending, and impact) directly affects the stability of the production process and the safety of storage and transportation.

[0003] Traditional pressure testing typically uses a mechanical press with weights for loading, and the degree of deformation is determined visually. However, due to the lack of an axial positioning mechanism, the paper tube frequently shifts horizontally during the test, causing the actual pressure application point to deviate from the predetermined test position, affecting the accuracy and repeatability of the test data. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the lack of an axial positioning mechanism in the existing technology leads to frequent horizontal displacement of the paper tube during the test, causing the actual pressure application point to deviate from the predetermined test position, thus affecting the accuracy and repeatability of the test data. Therefore, this invention proposes a testing machine for inspecting the toughness of chemical fiber paper tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing machine for inspecting the toughness of chemical fiber paper tubes includes a base, a fixed frame fixedly connected to the top of the base, a connecting seat fixedly connected to the fixed frame, an mounting plate provided on the connecting seat, a pressure block provided below the mounting plate, and a load base fixedly connected to the top of the base.

[0007] Also includes:

[0008] A driving mechanism is provided on the connecting seat, and the driving mechanism is used to drive the pressure block to move vertically and horizontally.

[0009] A fixing mechanism is provided on the carrier seat and is used to limit and fix the paper tube.

[0010] Preferably, the drive mechanism includes a lead screw rotatably connected to the connecting seat, a T-shaped block threaded onto the lead screw, a pair of cylinders fixedly connected to the bottom of the T-shaped block, the bottom output end of the cylinders fixedly connected to the mounting plate, and one end of the lead screw extending to the outside of the connecting seat and fixedly connected to a rocker wheel.

[0011] The mounting plate is equipped with disassembly and assembly parts that facilitate quick assembly and disassembly of the pressure block by the operator.

[0012] Preferably, the disassembly component includes a pair of vertical plates 1 fixedly connected to the top of the pressure block, a second vertical plate 2 fixedly connected to the top of the mounting plate, and the second vertical plate 2 having two opposite sides of the first vertical plate. A rectangular plate is provided on the opposite side of the first vertical plate and the second vertical plate. The same telescopic rod is fixedly connected to the opposite side wall of the rectangular plate and the second vertical plate, and a spring is sleeved on the telescopic rod. A limit rod is fixedly connected to the side wall of the rectangular plate away from the second vertical plate, and the limit rod and the first vertical plate are horizontally slidably inserted into each other.

[0013] Preferably, the two ends of the spring are fixedly connected to the second vertical plate and the rectangular plate respectively, and the first vertical plate has a socket for easy insertion of the limiting rod.

[0014] Preferably, the fixing mechanism includes a placement groove formed on the top of the carrier, a pair of clamping blocks are horizontally slidably connected in the placement groove, and screws are rotatably connected to the opposite sidewalls of the two clamping blocks, and the screws are threadedly connected to the carrier.

[0015] Preferably, one end of the screw extends to the outside of the carrier and is fixedly connected to a rocker wheel.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] This invention, through the design of a drive mechanism and a fixing mechanism, allows the paper tube to be placed horizontally in the placement slot during operation. The synchronous rotation of the two side rocker wheels drives the screws, causing the bidirectional clamping blocks to move smoothly towards each other, achieving undamaged clamping of both ends of the paper tube. Guided by the screw drive mechanism, the pressure block can flexibly adjust the test point position horizontally. Combined with the vertical pressure action of the cylinder, multi-point continuous testing of different positions on the paper tube is achieved. This design not only ensures the stability, accuracy, and repeatability of the testing process but also significantly improves testing efficiency. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-3 A testing machine for inspecting the toughness of chemical fiber paper tubes includes a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a connecting seat 3 fixedly connected to the fixed frame 2, a mounting plate 4 mounted on the connecting seat 3, and a pressure block 5 positioned below the mounting plate 4. The pressure block 5 is used to press the paper tube, and a pressure sensor of model Honeywell TJE can be installed on the pressure block 5 for precise detection, thereby accurately testing the toughness of the paper tube. The pressure sensor is existing technology and will not be described in detail here. A load base 6 is fixedly connected to the top of the base 1.

[0025] Also includes:

[0026] The drive mechanism is mounted on the connecting seat 3 and is used to drive the pressure block 5 to move vertically and horizontally.

[0027] The fixing mechanism is set on the carrier 6 and is used to limit and fix the paper tube.

[0028] The drive mechanism includes a lead screw 41 rotatably connected to the connecting seat 3. A T-block 42 is threaded onto the lead screw 41, and a pair of cylinders 44 are fixedly connected to the bottom of the T-block 42. The output end of the cylinders 44 is fixedly connected to the mounting plate 4. The lead screw 41 drives the precise horizontal positioning of the pressure block 5, while the cylinders 44 provide stable vertical pressure, ensuring the controllability of the testing process. One end of the lead screw 41 extends to the outside of the connecting seat 3 and is fixedly connected to a rocker wheel 43. The rocker wheel 43 is manually adjustable for fine adjustments, while the cylinders 44 drive the efficient and repeatable pressure action to meet different testing needs.

[0029] Mounting plate 4 is equipped with disassembly and assembly parts that facilitate quick disassembly and assembly of pressure block 5 by operators.

[0030] The assembly / disassembly system includes a pair of vertical plates 51 fixedly connected to the top of the pressure block 5. A second vertical plate 52 is fixedly connected to the top of the mounting plate 4, with the second vertical plate 52 positioned opposite the two vertical plates 51. A rectangular plate 53 is positioned on the opposite side of the vertical plates 51 and 52. A telescopic rod 54 is fixedly connected to the opposite sidewalls of the rectangular plate 53 and the second vertical plate 52. The telescopic rod 54 provides a preset trajectory for the extension of the spring 55, preventing deformation of the spring 55 and affecting the stable reset and locking effect. The spring 55 is fitted onto the telescopic rod 54. A limiting rod 56 is fixedly connected to the sidewall of the rectangular plate 53 away from the second vertical plate 52, and the limiting rod 56 and the vertical plate 51 slide horizontally together. The spring 55 limiting mechanism allows the pressure block 5 to be disassembled and assembled without tools; replacement can be completed simply by pressing the rectangular plate 53, significantly improving testing efficiency. Different materials or shapes of pressure blocks 5 (such as rubber or metal) can be used to meet different testing needs, adapting to diverse testing standards.

[0031] The two ends of the spring 55 are fixedly connected to the vertical plate 52 and the rectangular plate 53 respectively. The vertical plate 51 has a socket 57 for easy insertion of the limiting rod 56.

[0032] The fixing mechanism includes a placement groove 61 on the top of the carrier 6. A pair of clamping blocks 63 are horizontally slidably connected within the placement groove 61. Screws 62 are rotatably connected to the opposite sidewalls of the two clamping blocks 63, and the screws 62 are threadedly connected to the carrier 6. The clamping blocks 63 driven by the twin screws 62 can be adjusted synchronously or independently, suitable for chemical fiber paper tubes of different diameters, ensuring stable clamping without damaging the sample.

[0033] One end of the screw 62 extends to the outside of the carrier 6 and is fixedly connected to a rocker wheel 64. The size and shape of the rocker wheel 64 are designed in accordance with ergonomic principles, making it comfortable for the operator to hold and easy and quick to operate, which can effectively reduce the labor intensity of the operator and improve work efficiency.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] Sample fixing stage: The operator first places the paper tube to be tested horizontally in the placement slot 61 of the carrier 6, and drives the screw 62 to rotate by synchronously rotating the two side rollers 64, which in turn drives the two clamping blocks 63 to move smoothly towards each other. When the anti-slip texture of the clamping block 63 is in complete contact with the surface of the paper tube, the rotation stops to ensure that the sample is axially fixed without deviation.

[0036] Test component assembly: The installation of pressure block 5 is completed by a quick disassembly and assembly mechanism: Press the rectangular plate 53 to compress the spring 55, and after the limit rod 56 is fully retracted, take out the vertical plate 51 at the top of the pressure block 5 along with the pressure block 5 vertically downward. After selecting a suitable pressure block 5, release the pressure and the spring 55 will automatically reset. The limit rod 56 will be locked into the socket 57. This design supports the replacement of different pressure blocks 5.

[0037] Test positioning adjustment: Rotate the rocker wheel 43 through the lead screw 41 to drive the T-block 42 to move horizontally to the test point, start the cylinder 44 to push the mounting plate 4 to descend vertically, and observe the deformation of the paper tube.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
