Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a canvas tension testing device. Background Technology

[0002] A canvas tension testing device is a specialized instrument used to test the tensile strength of canvas materials. It typically consists of a fixed support and a movable clamp. By clamping a canvas sample between the clamps and applying gradually increasing tension, the maximum load-bearing capacity of the canvas is tested. The test results can be used to evaluate the quality and durability of the canvas, enabling quality control and improvement during canvas product manufacturing. However, existing canvas tension testing devices still have the following problems in practical use:

[0003] Existing canvas tension testing equipment cannot stop immediately when the canvas tension reaches its limit and tears during actual use, which makes the test data prone to deviation and has poor practicality. In addition, the existing canvas tension testing equipment is manually clamped during use, which may result in loosening or failure to clamp properly, thus reducing testing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by proposing a canvas tension testing device, which improves the poor practicality and low efficiency of existing canvas tension testing devices.

[0005] A canvas tension testing device includes: a base plate, a first support plate, a tensioning mechanism, a clamping mechanism, and a tensile testing device. The base plate has a first support plate at its upper end, and a baffle is connected to the upper end of the first support plate. The tensioning mechanism is provided on the side of the first support plate, and the clamping mechanism is connected to the side of the tensioning mechanism. A tensile testing device is connected between the first support plate and the clamping mechanism. A tear detection mechanism is connected to the side of the tensioning mechanism. The clamping mechanism clamps the canvas body.

[0006] Preferably, the stretching mechanism includes a first drive motor, a first threaded rod, a second support plate, and a slide bar. The stretching mechanism is provided on the side of the first support plate, and the output shaft of the stretching mechanism is connected to the first threaded rod. The second support plate is provided on the upper end of the base plate. The first threaded rod is rotatably connected to the second support plate. Two slide bars are symmetrically arranged between the first support plate and the second support plate, and the slide bars are located on the side of the first threaded rod.

[0007] Preferably, two third support plates are slidably connected to the side of the slide rod, and a housing is symmetrically embedded in the inner side of the third support plate. A first slider is slidably connected to the housing, and a first spring post is provided inside the housing. The upper end of the first spring post is connected to the first slider, and the upper end of the first slider is connected to a first connecting block.

[0008] Preferably, the clamping mechanism includes a second drive motor, a second threaded rod, a magnetic block, and an infrared sensor. The second drive motor is provided at the upper end of the first connecting block, and the output shaft of the second drive motor is connected to the second threaded rod. The second threaded rod is threadedly connected to the first connecting block and the third support plate. Magnetic blocks are provided on the sides of both the third support plate and the first connecting block, and infrared sensors are embedded in the sides of the magnetic blocks.

[0009] Preferably, the tear detection mechanism includes a connecting ring, a slide groove, a second slider, a second spring post, and an alarm switch. A connecting ring is provided on the side of the first threaded rod. The connecting ring is provided on the side of the second support plate. Two slide grooves are symmetrically opened on the inner side of the connecting ring. A second slider is slidably arranged on the inner side of the slide groove. Two second spring posts are symmetrically arranged on the inner side of the slide groove. The upper end of the second spring post is connected to the second slider. An alarm switch is provided on the inner side of the slide groove.

[0010] Preferably, the tension detection device includes a tension gauge, a pull rod, and a second connecting block. The tension gauge is connected to the side of the first support plate, the pull rod is provided on the side of the tension gauge, the end of the pull rod is connected to the second connecting block, and the second connecting block is connected to the third support plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. Equipped with a tear detection mechanism, when the tension of the canvas body reaches its limit during use, the canvas body will be pulled and torn. When the canvas body is torn, the first threaded rod loses its tension on the canvas body, causing the first threaded rod to rotate faster, which drives the second slider to slide in the slide groove, triggering the alarm switch. At this time, an alarm can be issued directly, making it easy to stop the device in time and obtain accurate values.

[0013] 2. Equipped with a clamping mechanism, during use, the canvas body is placed between the magnetic blocks. The infrared sensor detects that the canvas body has been placed and simultaneously activates the second drive motor. The second drive motor drives the second threaded rod to rotate, which in turn causes the first connecting block to fit against the third support plate. At the same time, the two magnetic blocks attract each other, clamping the canvas body. This makes operation convenient and improves efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-7As shown, a canvas tension testing device includes: a base plate 1, a first support plate 2, a tensioning mechanism 4, a clamping mechanism 5, and a tensile testing device 7. The base plate 1 is provided with the first support plate 2 at its upper end, and a baffle 3 is connected to the upper end of the first support plate 2. The tensioning mechanism 4 is provided on the side of the first support plate 2, and the clamping mechanism 5 is connected to the side of the tensioning mechanism 4. The tensile testing device 7 is connected between the first support plate 2 and the clamping mechanism 5. The tensioning mechanism 4 is connected to the side of the tear detection mechanism 6. The clamping mechanism 5 clamps the canvas body 8. When the device is in use, the canvas body 8 is clamped by the clamping mechanism 5, and then the tensioning mechanism 4 is activated to stretch and test the tension of the canvas body 8. The tension data is monitored by the tensile testing device 7, and the tear detection mechanism 6 monitors whether the canvas body 8 has reached the tension limit and is torn.

[0024] The tensioning mechanism 4 includes a first drive motor 41, a first threaded rod 42, a second support plate 43, and a slide bar 44. The tensioning mechanism 4 is arranged on the side of the first support plate 2. The output shaft of the tensioning mechanism 4 is connected to the first threaded rod 42. The second support plate 43 is arranged on the upper end of the base plate 1. The first threaded rod 42 is rotatably connected to the second support plate 43. Two slide bars 44 are symmetrically arranged between the first support plate 2 and the second support plate 43. The slide bars 44 are arranged on the side of the first threaded rod 42. When the device is in use, after the canvas body 8 is clamped, the first drive motor 41 is started, which drives the first threaded rod 42 to rotate. During the rotation of the first threaded rod 42, one of the third support plates 51, which is threaded to the first threaded rod 42, slides on the side of the slide bar 44. The other third support plate 51 is fixedly connected to the base plate 1. At this time, the tension of the canvas body 8 can be tested.

[0025] The slide bar 44 has two third support plates 51 slidably connected to its side. The inner side of the third support plate 51 is symmetrically embedded with a housing 52. The housing 52 is slidably connected to a first slider 53. The housing 52 is provided with a first spring post 54. The upper end of the first spring post 54 is connected to the first slider 53. The upper end of the first slider 53 is connected to a first connecting block 55.

[0026] The clamping mechanism 5 includes a second drive motor 56, a second threaded rod 57, a magnetic block 58, and an infrared sensor 59. The second drive motor 56 is mounted on the upper end of the first connecting block 55. The output shaft of the second drive motor 56 is connected to the second threaded rod 57. The second threaded rod 57 is threadedly connected to the first connecting block 55 and the third support plate 51. Magnetic blocks 58 are mounted on the sides of both the third support plate 51 and the first connecting block 55. Infrared sensors 59 are embedded on the sides of the magnetic blocks 58. When the device is in use, the canvas body 8 is placed between the two magnetic blocks 58. At this time, the infrared sensor 59 senses the canvas body 8 and starts the second drive motor 56. The second drive motor 56 drives the second threaded rod 57 to rotate. During the rotation of the second threaded rod 57, the first connecting block 55 is brought into contact with the third support plate 51, thus clamping the canvas body 8. At the same time, the first slider 53 slides inside the housing 52 during the movement of the first connecting block 55 to prevent the first connecting block 55 from deflecting during the movement, thereby improving the stability of the device.

[0027] The tear detection mechanism 6 includes a connecting ring 61, a slide groove 62, a second slider 63, a second spring post 64, and an alarm switch 65. The connecting ring 61 is located on the side of the first threaded rod 42 and on the side of the second support plate 43. Two slide grooves 62 are symmetrically arranged inside the connecting ring 61. The second slider 63 slides within the slide grooves 62, and two second spring posts 64 are symmetrically arranged within the slide grooves 62. The upper end of each second spring post 64 is connected to the second slider 63. The alarm switch 65 is located inside the slide grooves 62. When the device is in use, when the tension of the canvas body 8 reaches its limit, the canvas body 8 is torn. When the canvas body 8 is torn, the rotation speed of the first threaded rod 42 increases. This increased rotation speed causes the second slider 63 to slide within the slide groove 62 and simultaneously contact the alarm switch 65, triggering an alarm that the canvas body 8 is torn. This allows for timely stopping of the device and obtaining accurate values.

[0028] The tension testing device 7 includes a tension gauge 71, a pull rod 72, and a second connecting block 73. The tension gauge 71 is connected to the side of the first support plate 2, and the pull rod 72 is provided on the side of the tension gauge 71. The end of the pull rod 72 is connected to the second connecting block 73, and the second connecting block 73 is connected to the third support plate 51. When the device is in use, during the tension test, the pull rod 72 connected to the second connecting block 73 is pushed by the third support plate 51 to move towards the tension gauge 71, thereby feeding back the tension to the tension gauge 71. The tension of the canvas body 8 can be obtained from the value obtained by the tension gauge 71.

[0029] In use, the canvas body 8 is first placed between two magnetic blocks 58. At this time, the infrared sensor 59 detects the canvas body 8 and starts the second drive motor 56. The second drive motor 56 drives the second threaded rod 57 to rotate. During the rotation of the second threaded rod 57, the first connecting block 55 is brought into contact with the third support plate 51, thus clamping the canvas body 8. At the same time, the first slider 53 slides inside the housing 52 during the movement of the first connecting block 55 to prevent the first connecting block 55 from deflecting during the movement, thereby improving the stability of the device.

[0030] After the canvas body 8 is clamped, the first drive motor 41 is started, and the first threaded rod 42 is rotated by the first drive motor 41. During the rotation of the first threaded rod 42, one of the third support plates 51, which is threadedly connected to the first threaded rod 42, slides on the side of the slide rod 44. The other third support plate 51 is fixedly connected to the base plate 1. At this time, the tension test of the canvas body 8 can be performed.

[0031] During the tension test, the third support plate 51 pushes the pull rod 72 connected by the second connecting block 73 to move towards the tension gauge 71, thereby feeding the tension back to the tension gauge 71. The tension of the canvas body 8 can be obtained from the value obtained by the tension gauge 71.

[0032] When the tension of the canvas body 8 reaches its limit, the canvas body 8 is torn. When the canvas body 8 is torn, the rotation speed of the first threaded rod 42 increases. The increased rotation speed of the first threaded rod 42 drives the second slider 63 to slide in the slide groove 62 and simultaneously contact the alarm switch 65. At this time, an alarm can be directly issued. The canvas body 8 is torn, which makes it easy to stop the device in time and obtain accurate values.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
