Description

Technical Field

[0001] This utility model relates to the field of yarn strength testing technology, and in particular to a yarn strength performance testing device. Background Technology

[0002] During the production process, yarn is subjected to many complex mechanical actions, and during weaving, it is subjected to deformation phenomena such as stretching, bending and twisting. Therefore, the quality of yarn has a great impact on the output and quality of fabric. For this reason, after the yarn is produced, a strength testing device is needed to test its strength.

[0003] Current strength testing devices typically test yarn by placing a winding roller around a fixed shaft, holding the roller still, and fixing the yarn from the roller onto a tensile tester. The tester is then moved to measure the tensile strength. However, because it's difficult to keep the winding roller completely stable with one hand, even slight hand movements are transmitted to it, causing fluctuations in the tensile tester's readings. This results in inaccurate data reflecting the yarn's true strength, ultimately affecting the overall accuracy of the test results. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to keep the winding roller completely stable when operating with one hand, and that slight shaking of the hand will be transmitted to the winding roller, directly causing fluctuations in the data detected by the tension gauge. Therefore, this invention proposes a yarn strength performance testing device.

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

[0006] A yarn strength performance testing device includes two mounting plates that slide synchronously in opposite directions. A tension gauge is fixedly mounted on one of the mounting plates, and a disassembly and assembly seat is vertically slidably inserted into the other mounting plate. A rectangular column is fixedly mounted on the disassembly and assembly seat, and the rectangular column has an inner cavity. A winding tube is sleeved on the rectangular column. The device also includes:

[0007] A fixing component is disposed on the rectangular post and is used to limit and fix the winding tube.

[0008] The disassembly and assembly component is mounted on the mounting plate, and the disassembly and assembly component facilitates the operator to disassemble and assemble the disassembly and assembly base.

[0009] A drive component drives the two mounting plates to slide synchronously in opposite directions.

[0010] Preferably, the fixing component includes:

[0011] Connecting plate, the connecting plate is fixedly connected to the top of the rectangular column;

[0012] The screw is threadedly connected to the connecting plate;

[0013] A lifting block is rotatably connected to the bottom end of the screw.

[0014] Connecting plates, which are arranged in pairs, are embedded in and horizontally slidably connected to the rectangular column.

[0015] Preferably, the fixing component further includes:

[0016] An arc-shaped abutment plate is fixedly connected to the opposite ends of the two connecting plates, and the arc-shaped abutment plate is in contact with the inner wall of the winding tube;

[0017] The connecting ear is fixedly connected to the opposite sidewalls of the lifting plate and the connecting block, and the connecting ear is located in the inner cavity of the rectangular column.

[0018] The traction rod is hinged to the connecting lug.

[0019] Preferably, the top of the mounting / dismounting base is fixedly connected to a support platform for supporting the winding tube, and the rectangular column is fixedly connected to the top of the support platform.

[0020] Preferably, the disassembly / assembly assembly includes:

[0021] A sliding rod that slides through the mounting plate;

[0022] The insert is fixedly connected to one end of the slide rod, and the insert and the mounting / dismounting seat are horizontally inserted into each other;

[0023] A spring is sleeved on the slide rod, and both ends of the spring are fixedly connected to the mounting plate and the insert block, respectively.

[0024] The slot is provided on the mounting base, and the slot and the plug are correspondingly provided;

[0033] Compared with the prior art, the advantages of this utility model are as follows:

[0034] This invention utilizes a combination of fixing and disassembly components. A rotating screw drives a lifting block downwards, which, via a traction rod, causes an arc-shaped abutment to press tightly against the inner wall of the winding tube. Both ends of the yarn are fixed to the winding tube, with one end connected to a tension gauge. Starting the motor moves a plate that pulls the mounting plate, recording the yarn's breaking tensile force in real time. No manual support is required, ensuring the winding tube's stability during testing and eliminating data deviations caused by shaking. This allows the tension gauge to accurately reflect the yarn's true strength, providing reliable data support for testing. Attached Figure Description

[0045] 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.

[0046] Reference Figures 1-3 The yarn strength performance testing device includes two mounting plates 1 that slide synchronously in opposite directions. A tension gauge 2 is fixedly mounted on one mounting plate 1. The tension gauge 2 is used to facilitate real-time monitoring of tension by the operator to determine the tensile strength the yarn can withstand. The gauge model is preferred but not limited to the IMADA DS2-series. A disassembly / assembly base 3 is vertically slidably inserted into the other mounting plate 1. A rectangular post 5 is fixedly mounted on the disassembly / assembly base 3, and the rectangular post 5 has an inner cavity. A winding tube 4 is sleeved on the rectangular post 5. The device also includes…

[0047] The fixing component is set on the rectangular column 5. The fixing component is used to limit and fix the winding tube 4. The purpose of setting the fixing component is to fix the winding tube 4 after installation and prevent the winding tube 4 from rotating, which would affect the detection of yarn strength.

[0048] The disassembly and assembly component is set on the mounting plate 1. The disassembly and assembly component makes it easy for operators to disassemble and assemble the disassembly and assembly base 3. The purpose of the replaceable setting of the disassembly and assembly base 3 is to replace the rectangular post 5 so that the rectangular post 5 can be matched with the actual winding tube 4, ensuring that the winding tube 4 can be fitted onto the rectangular post 5.

[0049] The drive assembly drives two mounting plates 1 to slide synchronously in opposite directions. Under the action of the drive assembly, the winding tube 4 and the tension gauge 2 are relatively far apart, allowing the tension gauge 2 to detect the tension and strength of the yarn.

[0050] Reference Figure 3 The fixing components include: a connecting plate 51, a screw 52, ​​a lifting block 53, and a connecting plate 54.

[0051] The connecting plate 51 is fixedly connected to the top of the rectangular column 5; the screw 52 is threadedly connected to the connecting plate 51; the lifting block 53 is rotatably connected to the bottom of the screw 52; and the paired connecting plates 54 are embedded and horizontally slidably connected to the rectangular column 5.

[0052] The fixing components also include: an arc-shaped abutment 55, a connecting lug 56, and a traction rod 57.

[0053] An arc-shaped abutment 55 is fixedly connected to the opposite ends of two connecting plates 54, and the arc-shaped abutment 55 contacts the inner wall of the winding tube 4; a connecting ear 56 is fixedly connected to the opposite side walls of the lifting block 53 and the connecting plate 54, and the connecting ear 56 is located in the inner cavity of the rectangular column 5. The traction rod 57 is hinged to the connecting ear 56.

[0054] The top of the mounting base 3 is fixedly connected to a support platform 6 for supporting the winding tube 4, and the rectangular column 5 is fixedly connected to the top of the support platform 6.

[0055] It should be noted that the operator can rotate the screw 52 to move the lifting block 53 down, and pull the connecting plate 54 through the traction rod 57 to make the arc-shaped abutment 55 press against the inner wall of the winding tube 4, thus fixing the winding tube 4 during strength testing.

[0056] Reference Figure 2 The components to be disassembled and assembled include:

[0057] Slide rod 31 slides through mounting plate 1;

[0058] Insert 32 is fixedly connected to one end of slide bar 31, and insert 32 and disassembly base 3 are horizontally inserted into each other;

[0059] Spring 33 is sleeved on slide rod 31, and both ends of spring 33 are fixedly connected to mounting plate 1 and insert block 32 respectively;

[0060] Slot 34 is provided on the mounting base 3, and slot 34 and insert block 32 are correspondingly provided;

[0061] The groove 35 is formed on the top of the mounting plate 1, and the mounting base 3 and the groove 35 are vertically slidably inserted into each other.

[0062] It should be noted that the spring force of the spring 33 allows the insert block 32 to be stably inserted into the slot 34, thereby locking the mounting base 3; the groove 35 prevents the mounting base 3 from shifting.

[0063] Reference Figure 1 The drive components include: a base 7, a bidirectional lead screw 71, a motor 72, a moving plate 73, a limit rod 74, and a slide 75.

[0064] The base 7 and two mounting plates 1 are matched; the bidirectional lead screw 71 is rotatably connected to the base 7; the motor 72 is fixedly connected to the base 7 and is used to drive the bidirectional lead screw 71 to rotate; the moving plate 73 is threadedly connected to the bidirectional lead screw 71; the limiting rod 74 is fixedly connected to the base 7 and the limiting rod 74 and the moving plate 73 are horizontally slidably connected; the slide groove 75 is opened on the top of the base 7 and the moving plate 73 and the slide groove 75 are horizontally slidably connected.

[0065] It should be noted that the combined action of the slide 75 and the limiting rod 74 enables the two moving plates 73 to move stably horizontally along the axis of the bidirectional lead screw 71.

[0066] The functional principle of this utility model can be explained through the following operation methods:

[0067] First, the winding tube 4 is placed on the rectangular column 5. The rotating screw 52 drives the lifting block 53 to move down. The traction rod 57 pulls the connecting plate 54 so that the arc-shaped abutment plate 55 presses against the inner wall of the winding tube 4 to prevent the winding tube 4 from rotating during the strength test.

[0068] Next, the yarn is wound around the winding tube 4 and both ends are fixed. One end is connected to the tension gauge 2, and the other end is wound around the winding tube 4 and fixed on the winding tube 4.

[0069] The motor 72 of the drive assembly is started, which drives the bidirectional lead screw 71 to rotate, causing the two moving plates 73 to slide back and forth along the slide groove 75 and the limit rod 74, and simultaneously pull the mounting plate 1; at this time, the tension gauge 2 monitors the tension borne by the yarn in real time until the yarn breaks and records the strength data.

[0070] When it is necessary to remove the mounting bracket 3, pull the slide bar 31, the spring 33 is compressed, causing the insert 32 to disengage from the slot 34, and the mounting bracket 3 can be taken out vertically upward from the groove 35.

[0071] 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.
