Description

Technical Field

[0001] This application relates to the technical field of textile performance product testing, and in particular to a hammer-and-thread-snagging performance testing device. Background Technology

[0002] Since textiles are made of threads, snagging can cause significant damage, affecting not only their strength and durability but also their appearance. Therefore, anti-snagging performance testing is necessary during textile production. This testing plays a crucial role in the industrial production of the textile industry.

[0003] In previous tests of textile anti-snagging properties, the common method was to make the fabric into a ring shape and then place it on a rotating drum. To secure the fabric to the drum, two rubber rings were placed at both ends of the drum to create tension on the fabric. However, using rubber rings to secure the ring-shaped fabric required operators to stretch each ring, a cumbersome and time-consuming process that needs improvement. Summary of the Invention

[0004] The purpose of this application is to provide a hammer-snagging performance testing device for convenient fixing of circular fabric.

[0005] This application provides a nail hooking performance testing device with the following technical solution: It includes a body, a roller and an active plate rotatably connected to the body, a driving component connected to the body for driving the active plate to rotate, a plurality of tensioning plates slidably connected to the roller, each tensioning plate connected to a guide rod, the roller having guide grooves corresponding to the guide rods, each guide rod connected to a passive rod, the end of the passive rod away from the guide rod protruding from the roller, the active plate having arc-shaped grooves corresponding to the passive rods for sliding cooperation with the passive rods, the distance from one end of the arc-shaped groove to the axis of the active plate being greater than the distance from the other end of the arc-shaped groove to the axis of the active plate, and a hooking assembly connected to the body for hooking the annular fabric mounted on the roller.

[0006] By adopting the above technical solution, the operator places the annular fabric onto the roller, which then wraps around all the tensioning plates. The driving component drives the active plate to rotate around its own axis. The inner wall of the arc-shaped groove abuts against the passive rod, causing the passive rod to slide away from the axis of the active plate. That is, each tensioning plate and guide rod slides away from the axis of the roller. The sliding cooperation between the guide rod and the guide groove guides and limits the sliding of the tensioning plate, thereby improving the stability of the tensioning plate sliding and allowing each tensioning plate to better tension the annular fabric, thus fixing the annular fabric onto the roller and facilitating its installation and fixation. The active plate continues to rotate, and through the cooperation between the inner wall of the arc-shaped groove and the passive rod, it drives the roller to rotate around its own axis. This causes the annular fabric to rotate around the axis of the roller, enabling the hook assembly to hook the annular fabric installed on the roller.

[0007] Optionally, each tensioning plate has a positioning plate at one end, the positioning plate being used to abut against the annular fabric, and when the annular fabric abuts against the positioning plate, the annular fabric surrounds all the tensioning plates.

[0008] By adopting the above technical solution, when installing the ring-shaped fabric, one end of the ring-shaped fabric abuts against the positioning plate, so that the ring-shaped fabric can be installed more accurately in the corresponding position, and the tensioning plate can better tension the ring-shaped fabric.

[0009] Optionally, each tensioning plate is slidably connected to a stop plate on the side away from the guide rod. The stop plate is used to abut against the annular fabric. The tensioning plate is connected to a linkage structure. When the roller rotates, the tensioning plate drives the stop plate to slide away from the roller through the linkage structure. When the roller stops rotating, the tensioning plate drives the stop plate to slide closer to the roller through the linkage structure.

[0010] By adopting the above technical solution, when the roller rotates, the tensioning plate, through a linkage structure, drives the abutment plate to slide away from the roller. The abutment plate comes into contact with the annular fabric, further tensioning the annular fabric and improving its stability on the roller. This avoids the cumbersome operation of spreading the rubber ring during tensioning, as is done with traditional methods. When the roller stops rotating, the tensioning plate, through the linkage structure, drives the abutment plate to slide closer to the roller, separating the abutment plate from the annular fabric. This facilitates the removal of the annular fabric and improves operational convenience.

[0011] Optionally, the linkage structure includes a magnetic block connected to one side of the abutment plate, an elastic element connected to each magnetic block, and a plurality of magnetic blocks slidably connected to the tension plate. The magnetic blocks correspond one-to-one with the abutment plate and are used to magnetically attract the magnetic blocks. The tension plate is provided with centrifugal grooves corresponding one-to-one with the abutment plate. One end of the centrifugal groove corresponds to the magnetic block, and the distance from one end of the centrifugal groove to the axis of the roller is greater than the distance from the other end of the centrifugal groove to the axis of the roller.

[0012] By adopting the above technical solution, when the drum is not rotating, the magnetic block is located at the end of the centrifugal tank closest to the drum's axis. At this time, the magnetic block has the greatest attraction to the magnetic stripe, and the magnetic block tends to move towards the elastic element. The elastic element is compressed, undergoes elastic deformation, and tends to maintain its elastic return. When the drum rotates around its own axis, due to the inertia of the magnetic block, it will move to the end of the centrifugal tank away from the drum's axis. At the same time, the magnetic block is subjected to centrifugal force and remains at the end of the centrifugal tank away from the drum's axis. At this time, the magnetic block has the least attraction to the magnetic stripe, which is less than the elastic force of the elastic element's elastic return. Therefore, the elastic element elastically returns to its original position and forces the clamping plate to slide away from the drum's axis, further tensioning the annular fabric and improving the stability of the annular fabric fixed to the drum. When the drum stops rotating, under the mutual attraction between the magnetic block and the magnetic stripe, the magnetic block will move back to the end of the centrifugal tank closest to the drum's axis, allowing the clamping plate to release the annular fabric, thus facilitating the installation or removal of the annular fabric.

[0013] Optionally, there are several magnetic blocks, and all the magnetic blocks connected to the same abutment plate are distributed at intervals along the length direction of the abutment plate. The magnetic blocks are elongated, and all the magnetic blocks on the same abutment plate correspond to the corresponding magnetic blocks.

[0014] By adopting the above technical solution, multiple magnetic blocks are distributed at intervals along the length of the clamping plate. Combined with long strip magnetic blocks, the magnetic attraction between the clamping plate and the tensioning plate can be made more uniform and stable, thereby improving the stability of the clamping plate movement.

[0015] Optionally, both the tension plate and the abutment plate are elastic plates, and the side of the tension plate and the abutment plate away from the roller has an outer arc shape.

[0016] By adopting the above technical solution, the tensioning plate and the anti-shrink plate are elastic plates that can better fit the circular fabric, reduce damage to the fabric, and the outer arc surface design can make the contact between the fabric and the tensioning plate and the anti-shrink plate smoother, reduce fabric scratches, and at the same time better adapt to the shape of the circular fabric, enhancing the tensioning effect.

[0017] Optionally, the hook assembly includes a mounting plate connected to the machine body, a mounting rod connected to the mounting plate, a limiting rod connected to the mounting plate, a connecting chain connected to the mounting rod, and a hammer connected to the connecting chain. The mounting rod and the limiting rod are spaced apart. The extension directions of the mounting rod and the limiting rod are the same as the extension direction of the roller. The limiting rod is located between the mounting rod and the roller and is used to abut against the connecting chain.

[0018] By adopting the above technical solution, during the use of the hammer snagging performance testing device, the connecting chain is wound around the limiting rod, and the hammer abuts against the annular fabric. When the roller rotates, the hammer continuously bounces on the surface of the annular fabric, and the annular fabric repeatedly hits the annular fabric to achieve the effect of simulating snagging.

[0019] Optionally, the limiting rod is connected to two limiting plates, and when the connecting chain abuts against the limiting rod, the connecting chain is located between the two limiting plates.

[0020] By adopting the above technical solution, the two limiting plates restrict the movement of the connecting chain, preventing the connecting chain from detaching from the limiting rod during the hammer's jumping motion.

[0021] Optionally, the mounting rod is connected to a connecting plate, the connecting plate is slidably connected to a connecting post, the connecting post is threaded with two nuts, the connecting plate is located between the two nuts, and the end of the connecting chain away from the hammer is connected to the connecting post.

[0022] By adopting the above technical solution, the height of the connecting column can be adjusted by the cooperation of the connecting column and the two nuts, that is, the distance between the hammer and the center line of the limiting rod can be adjusted. Different distances between the hammer and the center line of the limiting rod result in different hammer bounce amplitudes, which can simulate different test conditions.

[0023] Optionally, the mounting plate is connected to a placement seat, the placement seat having a placement groove for placing the hammer.

[0024] By adopting the above technical solution, when the hammer hooking performance testing device is not in use, the hammer can be placed in the placement slot for easy storage.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator places the circular fabric onto the roller, which wraps around all the tensioning plates. The drive unit drives the active plate to rotate around its own axis. The inner wall of the arc-shaped groove abuts against the passive rod, causing the passive rod to slide away from the axis of the active plate. That is, each tensioning plate and guide rod slides away from the axis of the roller. The sliding cooperation between the guide rod and the guide groove guides and limits the sliding of the tensioning plate, thereby improving the stability of the tensioning plate sliding and allowing each tensioning plate to better tension the circular fabric, thus fixing the circular fabric onto the roller and facilitating its installation and fixation. The active plate continues to rotate, and through the cooperation between the inner wall of the arc-shaped groove and the passive rod, it drives the roller to rotate around its own axis. That is, the circular fabric rotates around the axis of the roller, enabling the hook assembly to hook the circular fabric installed on the roller.

[0026] 2. When the drum is not rotating, the magnetic block is located at the end of the centrifugal trough closest to the drum's axis. At this time, the magnetic block has the strongest attraction to the belt magnetic block, and it tends to move towards the elastic element. The elastic element, under pressure, undergoes elastic deformation and tends to elastically return to its original position. When the drum rotates around its own axis, due to the inertia of the magnetic block, it will move to the end of the centrifugal trough furthest from the drum's axis. Simultaneously, under the action of centrifugal force, the magnetic block remains at the end of the centrifugal trough furthest from the drum's axis. At this time, the magnetic block has the weakest attraction to the belt magnetic block, which is less than the elastic force of the elastic element's elastic return. Therefore, the elastic element elastically returns to its original position and forces the clamping plate to slide away from the drum's axis, further tensioning the annular fabric and improving the stability of the annular fabric fixed to the drum. When the drum stops rotating, under the mutual attraction between the magnetic block and the belt magnetic block, the magnetic block will move back to the end of the centrifugal trough closest to the drum's axis, causing the clamping plate to release the annular fabric, thus facilitating the installation or removal of the annular fabric.

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail.

[0037] This application discloses a hammer-and-wire-hooking performance testing device.

[0038] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a body 1, which is rotatably connected to four rollers 11 and an active plate 12 at intervals. Each roller 11 corresponds to one active plate 12. The body 1 is fixedly connected to a drive unit 13, which corresponds to one active plate 12. The drive unit 13 is a motor. The drive unit 13 is externally connected to a controller (not shown in the attached figure). The signal output terminal of the controller is connected to the signal input terminal of the drive unit 13. The side of the active plate 12 closest to the drive unit 13 is fixedly connected to the output terminal of the drive unit 13. The drive unit 13 drives the active plate 12 to rotate around its own axis. The roller 11 is rotatably connected to the machine body 1 via bearings. Several tensioning plates 2 are slidably connected to the outer surface of each roller 11. Taking this embodiment as an example, there are six tensioning plates 2 on each roller 11. All tensioning plates 2 are evenly distributed around the axis of the roller 11. Each tensioning plate 2 is fixedly connected to a guide rod 21. The roller 11 has guide grooves 111 that correspond one-to-one with the guide rods 21. The guide rods 21 are inserted into the guide grooves 111 and slide in cooperation with the guide grooves 111. A passive rod 22 is fixedly connected to the end of each guide rod 21 away from the tensioning plate 2. The extension direction of the passive rod 22 is perpendicular to the extension direction of the guide rod 21. The roller 11 has oblong holes 112 corresponding to the guide grooves 111. The guide grooves 111 communicate with the oblong holes 112. The passive rod 22 is inserted into the oblong hole 112 and slides in cooperation with it. Part of the passive rod 22 is located inside the oblong hole 112, and the end of the passive rod 22 away from the guide rod 21 protrudes from the oblong hole 112. The driving plate 12 has arc-shaped grooves 121 corresponding to the passive rods 22. The end of the passive rod 22 away from the guide rod 21 is inserted into the arc-shaped groove 121 and slides in cooperation with it. The distance between one end of the arc-shaped groove 121 and the axis of the driving plate 12 is greater than the distance between the other end of the arc-shaped groove 121 and the axis of the driving plate 12.

[0039] Combination Figure 3 and Figure 4 As shown, each tensioning plate 2 has a positioning plate 23 fixedly connected to its outer surface. The positioning plate 23 is located at the end of the tensioning plate 2 near the drive member 13. When the annular fabric is installed, one end of the annular fabric abuts against the positioning plate 23, so that the annular fabric is accurately installed in the corresponding position. The annular fabric surrounds all tensioning plates 2.

[0040] Combination Figure 3 , Figure 6 and Figure 7As shown, each tensioning plate 2 has a slidingly connected abutment plate 3 on the side away from the guide rod 21. The abutment plate 3 is used to abut against the annular fabric. The tensioning plate 2 is connected to a linkage structure 4, which includes several magnetic blocks 41 fixedly connected to one side of the abutment plate 3, elastic elements 42 fixedly connected to each magnetic block 41, and several magnetic blocks 43 slidably connected inside the tensioning plate 2. All magnetic blocks 41 connected to the same abutment plate 3 are spaced apart along the length of the abutment plate 3. The tensioning plate 2 has a relief groove 24, and the abutment plate 3 is inserted into the relief groove 24 and fits against the inner wall of the relief groove 24. The tensioning plate 2 has a groove 25 corresponding to the magnetic blocks 41 one by one. Part of the magnetic block 41 is located in the groove 25. The elastic element 42 is a spring, one end of which is fixedly connected to the magnetic block 41, and the other end is fixedly connected to the inner wall of the groove 25. Tensioning plate 2 has centrifugal grooves 26 that correspond one-to-one with the abutment plate 3. The distance from one end of the centrifugal groove 26 to the axis of the roller 11 is greater than the distance from the other end of the centrifugal groove 26 to the axis of the roller 11. The end of the centrifugal groove 26 closest to the axis of the roller 11 corresponds to a magnetic block 41. The magnetic block 41 is an iron block, and the magnetic block 43 is a magnet. The magnetic blocks 41 and 43 are magnetically attracted to each other. The magnetic blocks 43 are elongated, and all the magnetic blocks 41 on the same abutment plate 3 correspond to the corresponding magnetic blocks 43. Both tensioning plate 2 and abutment plate 3 are elastic plates, and the side of tensioning plate 2 and abutment plate 3 away from the roller 11 has an outward arc shape.

[0041] Combination Figure 6 and Figure 8As shown, the machine body 1 is connected with four hooking assemblies 5 at intervals. Each hooking assembly 5 corresponds to a roller 11. Each hooking assembly 5 includes a mounting plate 51 fixedly connected to the machine body 1, a mounting rod 52 fixedly connected to the mounting plate 51, a limiting rod 53 fixedly connected to the mounting plate 51, a connecting chain 54 adjustablely connected to the mounting rod 52, and a hammer 55 fixedly connected to the connecting chain 54. The mounting plate 51 is L-shaped. The mounting rod 52 and the limiting rod 53 are spaced apart. The limiting rod 53 is located below the mounting rod 52 and between the mounting rod 52 and the roller 11. The extension directions of both the mounting rod 52 and the limiting rod 53 are the same as the extension direction of the roller 11. Two limiting plates 531 are fixedly connected to the limiting rod 53 at intervals. When the connecting chain 54 is suspended on the limiting rod 53, the connecting chain 54 is located between the two limiting plates 531. Mounting rod 52 is fixedly connected to connecting plate 56, which is inclined. Connecting post 57 is slidably connected to connecting plate 56. Connecting post 57 is threaded with two nuts 58. Connecting plate 56 is located between the two nuts 58. By rotating the two nuts 58, the position of connecting post 57 on connecting plate 56 can be adjusted. The end of connecting chain 54 away from hammer 55 is fixedly connected to connecting post 57, thereby adjusting the position of hammer 55. Mounting plate 51 is fixedly connected to placement seat 59, which has placement groove 591. Hammer 55 can be placed in placement groove 591 for installation.

[0042] The implementation principle of the hammer and wire-hooking performance testing device in this application embodiment is as follows: When the drum 11 is not rotating, the magnetic block 43 is located at one end of the centrifugal tank 26 near the axis of the drum 11. At this time, the magnetic block 43 has the greatest attraction to the magnetic block 41. The magnetic block 43 has a tendency to move towards the elastic member 42. The elastic member 42 is compressed and undergoes elastic deformation and tends to maintain elastic reset.

[0043] The operator places the annular fabric onto the roller 11, which wraps around all the tensioning plates 2. The driving component 13 drives the active plate 12 to rotate around its own axis. The inner wall of the arc-shaped groove 121 abuts against the passive rod 22, causing the passive rod 22 to slide away from the axis of the active plate 12. That is, each tensioning plate 2 and guide rod 21 slides away from the axis of the roller 11. The sliding cooperation between the guide rod 21 and the guide groove 111 guides and limits the sliding of the tensioning plate 2, thereby improving the stability of the sliding of the tensioning plate 2 and allowing each tensioning plate 2 to better tension the annular fabric, thus fixing the annular fabric on the roller 11 and facilitating the installation and fixation of the annular fabric. The active plate 12 continues to rotate, and through the cooperation between the inner wall of the arc-shaped groove 121 and the passive rod 22, it drives the roller 11 to rotate around its own axis, that is, the annular fabric rotates around the axis of the roller 11.

[0044] During the rotation of the roller 11, due to the inertia of the magnetic block 43, it will move to the end of the centrifugal trough 26 away from the axis of the roller 11. Simultaneously, under the action of centrifugal force, the magnetic block 43 remains at the end of the centrifugal trough 26 away from the axis of the roller 11. At this point, the attraction of the magnetic block 43 to the magnetic block 41 is minimal, and less than the elastic force of the elastic element 42. Therefore, the elastic element 42 elastically resets and forces the pressing plate 3 to slide away from the axis of the roller 11, further tensioning the annular fabric and improving the stability of the annular fabric fixed on the roller 11. When the roller 11 stops rotating, under the mutual attraction between the magnetic block 43 and the magnetic block 41, the magnetic block 43 will move back to the end of the centrifugal trough 26 near the axis of the roller 11, allowing the pressing plate 3 to release the annular fabric, thus facilitating the installation or removal of the annular fabric. The driving component 13 drives the active plate 12 to rotate in the opposite direction. The inner wall of the arc groove 121 abuts against the passive rod 22 and drives the passive rod 22 to slide towards the axis of the active plate 12. That is, each tensioning plate 2 and guide rod 21 slides towards the axis of the roller 11, so that each tensioning plate 2 loosens the annular fabric, which facilitates the disassembly of the annular fabric.

[0045] 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.
