Description

Technical Field

[0001] This utility model belongs to the technical field of glove performance testing, specifically relating to a cut resistance testing device and glove production equipment. Background Technology

[0002] In the glove manufacturing industry, glove performance testing equipment is a key tool for ensuring product quality and meeting industry standards and user needs. Glove performance testing equipment is categorized by physical performance testing methods into tensile strength testers, abrasion resistance testers, and cut resistance testers. The cut resistance tester is a specialized device used to evaluate the cut resistance of materials (such as gloves, fabrics, and leather). It is applied in industrial production and safety protection fields. Understanding the cut resistance of materials is crucial for ensuring personnel safety. This equipment simulates actual cutting scenarios to perform cut tests on materials and determine their cut resistance level.

[0003] To ensure gloves provide effective protection in actual use, manufacturers must conduct rigorous cut resistance tests on their produced gloves. Currently used cut resistance testing machines are complex in structure, expensive, and overly cumbersome to operate, resulting in low testing efficiency and making it difficult to meet the cut resistance testing needs of large-volume gloves.

[0004] Existing technologies include research addressing the problems of current cut resistance testing machines. For example, patent CN217059878U – a fire-fighting glove cut resistance testing machine – uses a clamping mechanism to fix the glove and performs a unidirectional cut test using a cutting device. This cannot simulate multi-angle, continuous cutting scenarios in actual use, and manual angle adjustment is inefficient and lacks clamping stability. Patent CN212159446U – a portable glove cut resistance testing machine – uses a motor to drive the test cylinder to rotate, but the transmission structure is complex, resulting in vibration interference with test accuracy and high maintenance costs. Furthermore, the poor stability of the cylinder support can easily lead to uneven contact pressure between the blade and the sample.

[0005] In summary, existing cut resistance testing machines lack a testing environment capable of simulating continuous multi-angle rotary cutting, the transmission mechanism is highly susceptible to interference during the testing process, and the rigidity of the test cylinder support structure is insufficient, severely impacting the reliability of the test data. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0006] The purpose of this utility model is to provide a cut resistance testing device and glove production equipment to solve the problems mentioned in the background art, such as the lack of a testing environment that can simulate multi-angle continuous rotational cutting in current cut resistance testing machines, the transmission mechanism being prone to interference in the testing process, and the insufficient rigidity of the test cylinder support structure, which seriously affects the reliability of test data.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cut resistance testing device, comprising a support frame and a testing cylinder. A bearing seat is fixed at each of the four top corners of the support frame. A drive shaft rotatably passes through each of the two sets of bearing seats located on both sides of the support frame and arranged opposite to each other. The two drive shafts are arranged in parallel. A drive wheel located inside the corresponding bearing seat is fixed at each end of a single drive shaft. Two drive wheels on the same drive shaft are arranged mirror-symmetrically. The two ends of the testing cylinder are rotatably supported on the four drive wheels of the two drive shafts. Four drive wheels form two support rolling points at each end of the test cylinder. The support rolling points are symmetrically distributed along the axial direction of the test cylinder, and each support rolling point is in contact with the annular line on the outer circumference of the test cylinder. Each end of the single drive shaft extends axially to the outer side of the corresponding bearing seat, and a pulley is fixed to one end of the extension. The pulley is connected to the output shaft of a rotary motor fixed on the support frame via a belt. The rotary motor drives the drive shaft to rotate around its own axis and drives the drive wheels to rotate synchronously via the belt and pulley. The drive wheels drive the test cylinder to rotate around its own axis through rotational friction.

[0008] Furthermore, a transmission wheel is fixed to the end of the output shaft of the rotary motor, and the transmission wheel is connected to the pulley via a belt drive.

[0009] Furthermore, a limiting baffle fixed to the drive shaft is provided on the side of the drive wheel near the corresponding bearing seat, and the end face of the limiting baffle facing the test cylinder forms an axial limiting fit with the end side of the test cylinder; the outer peripheral surface of the drive wheel away from the corresponding bearing seat is in rolling contact with the outer peripheral surface of the end of the test cylinder.

[0010] Furthermore, the test cylinder has several blade holders fixed laterally along its inner circumferential surface, and each blade holder has several simulated cutting blades evenly distributed along the axial direction of the test cylinder and inclined relative to the blade holder; a reinforcing ring is fitted at each of the outer ends of the test cylinder, and the outer circumferential surface of the reinforcing ring is in rolling contact with the outer circumferential surface of the drive wheel; an inspection door is hinged to the side of the test cylinder away from the pulley.

[0011] In addition to the above technical solutions, there are also glove production equipment equipped with this cut resistance testing device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model employs a design with four fixed bearing seats at the top corners of the support frame, and supports and rotates the test cylinder via two parallel drive shafts and drive wheels. This ensures the stability of the test cylinder during rotation, reduces testing errors caused by vibration or instability, and improves the accuracy and repeatability of the test. Furthermore, the test cylinder is rotatably supported on the four drive wheels of the two drive shafts, giving the test cylinder a self-rotation function. This achieves the purpose of multi-angle cut resistance simulation testing of gloves in actual use. Compared to existing unidirectional cutting methods, it can better simulate complex cutting scenarios and more accurately evaluate the cut resistance of gloves, helping to optimize product design and improve the safety and reliability of gloves in actual use. (The text also mentions a belt, but this seems unrelated to the main point about the test cylinder.) The design of using wheels and belts to transmit the power of the rotary motor to the drive shaft, thereby driving the drive wheel and test cylinder to rotate, effectively simplifies the transmission structure, reduces vibration and interference during transmission, improves test stability, reduces maintenance costs, and ensures the reliability of test results. Utilizing the rotational friction between the drive wheel and the test cylinder to drive the cylinder's rotation allows for flexible control of the cylinder's rotational speed through adjustments to the rotary motor's speed, enhancing the flexibility and adaptability of cut resistance testing. Through a rational layout and transmission method, efficient testing within a limited space is achieved, saving space resources, improving testing efficiency, reducing operating costs, and making the device easier to move and deploy, meeting the needs of different testing scenarios.

[0014] 2. This utility model uses four drive wheels to form two support rolling points, and each support rolling point forms a ring-shaped contact with the reinforcing rings fitted at both ends of the outer circumference of the test cylinder. This design significantly enhances the support rigidity of the test cylinder, ensures the stability of the test cylinder during rotation testing, reduces vibration and offset caused by uneven support, and effectively improves the accuracy and stability of the test. It provides a good foundation for simulated cutting tests. Furthermore, the limiting design of the limiting baffle effectively prevents the test cylinder from moving axially, ensuring that the test cylinder always stays in the correct position during rotation testing. This effectively avoids the problem of uneven contact pressure between the blade and the sample caused by deformation, movement, or shaking of the test cylinder, further improving the accuracy and reliability of the test and avoiding interference with the test results caused by axial movement of the test cylinder.

[0015] 3. This utility model uses two drive wheels arranged in a mirror-symmetrical manner on the same drive shaft to make the support and driving effect of the drive wheels on the test cylinder more balanced, reducing the instability of the test cylinder caused by installation deviation or uneven force of the drive wheels. On this basis, the outer peripheral surface of the drive wheel is set to roll contact with the outer peripheral surface of the end of the test cylinder, which increases the contact area between the drive wheel and the test cylinder, further improving the driving capability of the drive wheel on the test cylinder, enabling the test cylinder to rotate more stably and efficiently. At the same time, it also helps to disperse stress, reduce local wear, and thus extend the service life of the device.

[0016] 4. This utility model uses multiple inclined simulated cutting blades set inside the test cylinder to simulate a more complex and realistic cutting scenario by continuously rotating the glove material at multiple angles. Compared with the unidirectional or limited angle cutting methods in existing testing machines, it can more comprehensively evaluate the cut resistance of glove materials, thereby providing more accurate test data and providing reliable quality control basis for glove manufacturers.

[0017] 5. By hinged an inspection door on the side of the test cylinder away from the pulley, this utility model not only facilitates the loading and unloading of gloves, but also facilitates the installation, debugging, maintenance and replacement of components such as the blade holder and simulated cutting blade inside the test cylinder. This effectively improves the maintainability of the device, reduces maintenance and time costs, and also facilitates the cleaning and inspection of the inside of the test cylinder, ensuring that the testing device is always in good working condition.

[0024] The following embodiments are used to further illustrate the content of this utility model, and do not limit the application of this utility model. Example 1:

[0025] Please see Figures 1-5 This utility model provides a cut resistance testing device, including a support frame 1 for fixing and supporting, and a test cylinder 2 for cut resistance testing (the test cylinder 2 can be made of transparent material, which helps to observe the test situation in real time). A bearing seat 3 is fixed at each of the four corners of the top of the support frame 1. A drive shaft 4 for rotational transmission is rotatably inserted between two sets of bearing seats 3 located on both sides of the support frame 1 and arranged opposite to each other. The two drive shafts 4 are arranged in parallel. A drive wheel 5 located inside the corresponding bearing seat 3 is fixed at each end of a single drive shaft 4. The two drive wheels 5 on the same drive shaft 4 are mirror-symmetrically arranged. A drive wheel 5 is fixed to the drive shaft 4 on the side closest to the corresponding bearing seat 3. The upper limit baffle 6 is used to limit the test cylinder 2. The end face of the limit baffle 6 facing the test cylinder 2 forms an axial limiting fit with the end side of the test cylinder 2. A reinforcing ring 201 is fitted on each of the outer ends of the test cylinder 2 (the reinforcing ring can be made of wear-resistant material to help ensure the stability of rotation). The outer circumferential surface of the reinforcing ring 201 is in rolling contact with the outer circumferential surface of the drive wheel 5 away from the corresponding bearing seat 3. The two ends of the test cylinder 2 are rotatably supported on the four drive wheels 5 of the two drive shafts 4. The four drive wheels 5 form two support rolling points at each end of the test cylinder 2. The support rolling points are symmetrically distributed along the axial direction of the test cylinder 2 and each support rolling point is in contact with the annular line of the outer circumferential surface of the test cylinder 2.

[0026] Both ends of the single drive shaft 4 extend axially to the outer side of the corresponding bearing seat 3, and a pulley 7 is fixed to one end of the extension. The pulley 7 is connected to the transmission wheel 9 via the belt 8. The transmission wheel 9 is fixed to the output shaft end of the rotary motor 10 located on the support frame 1. The rotary motor 10 drives the drive shaft 4 to rotate around its own axis via the belt 8, the transmission wheel 9 and the pulley 7, and drives the drive wheel 5 to rotate synchronously. The drive wheel 5 drives the test cylinder 2 to rotate around its own axis through rotational friction, so that the test cylinder 2 has the function of self-rotation.

[0027] The test cylinder 2 has several fixed blade holders 202 for simulating cutting blades fixed laterally along its inner circumferential surface. Each blade holder 202 has several simulated cutting blades 203 evenly distributed along the axial direction of the test cylinder 2 and inclined relative to the blade holder 202. The end side of the test cylinder 2 away from the pulley 7 is hinged with an inspection door 204 for glove loading and unloading, making the glove cutting resistance simulation test more convenient and faster.

[0028] The working principle and usage process of this utility model are as follows: Figures 1-5As illustrated, after the cut resistance testing device is assembled, the operator installs the entire device onto the glove production equipment (the functions and structures of conventional equipment such as glove production equipment are well known in the field, and the connection settings are also common knowledge, so they will not be described in detail here, nor are they shown in the attached drawings). The purpose is to ensure the stability of the test cylinder during the rotation test, reduce test errors caused by vibration or instability, improve the accuracy and reliability of the test, and thus realize the simulation of more complex and realistic cutting scenarios by multi-angle continuous rotation of glove materials. This allows for a more comprehensive evaluation of the cut resistance performance of glove materials, thereby providing more accurate test data and a reliable quality control basis for glove manufacturers.

[0029] When the produced gloves need to undergo a cut resistance test, the operator first places the gloves to be tested into the test cylinder 2 through the inspection door 204. Since the rotary motor 10 is controlled by a control box or controller (the functions and structures of conventional equipment such as control boxes or controllers are well known in the art, and the connection settings are also common knowledge, so they will not be described in detail here, nor are they shown in the attached drawings), the operator then controls the rotary motor 10 to start by operating the control box or controller. At this time, the pulley 7 will drive the drive shaft 4 to rotate along with the rotation of the transmission wheel 9 under the drive of the rotary motor 10. 4. While rotating around its own axis, the drive wheel 5 rotates synchronously. The drive wheel 5, in turn, drives the test cylinder 2 to rotate around its own axis through rotational friction. At the same time, the glove placed inside the test cylinder 2 will tumble up and down inside the test cylinder 2 as the test cylinder 2 rotates. This causes the simulated cutting blade 203 installed inside the test cylinder 2 to continuously cut the tumbling glove from multiple angles, thereby simulating a more complex and realistic cutting scenario. This provides more accurate test data for comprehensively evaluating the cut resistance of glove materials, which helps to optimize product design and improve the safety and reliability of gloves in actual use. Example 2:

[0030] Please see Figures 1-5 As another objective of this utility model, a glove production equipment is provided, which is equipped with the above-mentioned cut resistance testing device. Therefore, the glove production equipment can obtain any of the beneficial effects of the cut resistance testing device described above, which will not be repeated here.
