Technical Field
[0001] This utility model relates to the field of Venetian blind slat production technology, and in particular to a strength testing device for Venetian blind slat production. Background Technology
[0002] Venetian blinds come in two types: fixed and movable. They are made of many thin slats connected and folded together. They not only provide ventilation, light blocking, and sound insulation, but can also be moved to provide shade, cool down, and decorate the room. Venetian blinds are made of various materials such as bamboo, wood, fiberglass, aluminum alloy, and currently popular plastic sheets and linen sheets. During production, the blind slats need to be tested to meet production requirements.
[0003] Currently, most Venetian blind slat strength testing devices use a simple clamping structure with parallel clamps and bolts or springs to fix the slats, and then apply pressure to conduct a bending compression test. However, due to the variety of materials and surface characteristics of the slats, this fixing method is difficult to provide stable fastening force, which can easily lead to the slats loosening and falling off during the test, posing a safety hazard. At the same time, insecure fixing can cause uneven stress on the slats, resulting in inaccurate test data and affecting quality assessment. Therefore, a strength testing device for Venetian blind slat production is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a strength testing device for the production of Venetian blind slats, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A strength testing device for the production of Venetian blind slats includes a base plate. A fixing plate, a mounting plate, and a square plate are fixedly installed on the top side of the base plate. Two connecting plates are provided between the mounting plate and the fixing plate. A pressure block is fixedly connected to one side of each of the two connecting plates. A connecting frame is fixedly installed on one side of the mounting plate. The connecting frame is F-shaped and has two placement slots on one side. The same slat body is placed in the two placement slots. The two pressure blocks face the two placement slots respectively. A driving component and a testing component are respectively provided on one side of the square plate and the fixing plate.
[0007] Preferably, the drive assembly includes a motor fixedly mounted on one side of a square plate, the output end of the motor rotatably passing through the square plate and the mounting plate and fixedly connected to a threaded rod, the other end of the threaded rod being rotatably connected to one side of the fixed plate, and a first synchronous pulley fixedly sleeved on the outer side of the threaded rod.
[0008] Preferably, the mounting plate has a circular hole, and a threaded post is provided in the circular hole. The two ends of the threaded post are rotatably connected to the opposite surfaces of the fixing plate and the square plate, respectively. A second synchronous pulley is fixedly sleeved on the outside of the threaded post, and the second synchronous pulley and the first synchronous pulley share the same synchronous belt.
[0009] Preferably, both the threaded column and the threaded rod are threaded with sliders on their outer sides. One side of each of the two connecting plates is fixedly connected to one side of each of the two sliders. The other side of each of the two sliders is fixedly connected to the same guide block. Two guide rods are fixedly installed between the connecting frame and the fixed plate, and the guide block is slidably sleeved on the two guide rods.
[0010] Preferably, the test assembly includes an electric push rod fixedly installed on one side of a fixed plate, the output end of the electric push rod passing through the fixed plate and fixedly connected to a squeezing plate, the squeezing plate being U-shaped and facing the curtain body, and a pressure sensor fixedly connected to the inner wall of one side of the squeezing plate.
[0011] Preferably, a controller is fixedly installed on one side of the fixed plate, and the controller is electrically connected to the motor, the electric push rod and the pressure sensor respectively.
[0012] Preferably, a protective cover is fixedly installed on one side of the connecting frame, and the protective cover is frame-shaped.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The strength testing device for the production of Venetian blind slats, through a drive assembly consisting of a motor, threaded rod, threaded column, first synchronous wheel, second synchronous wheel and synchronous belt, can synchronously drive two sliders to move, thereby driving the pressure block on the connecting plate to fasten the two ends of the slat body placed in the placement groove. Compared with the traditional clamping structure, this device provides a stable and balanced clamping force through threaded transmission, avoiding the problem of unstable fixing caused by material differences. With the guide block and guide rod guide limiting structure, it ensures that the pressure block is accurately pressed, effectively preventing the slats from loosening and falling off during the bending test, and eliminating safety hazards.

[0019] 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.
[0020] Reference Figure 1-4A strength testing device for the production of Venetian blind slats includes a base plate 1. A fixing plate 2, a mounting plate 3, and a square plate 4 are fixedly mounted on the top side of the base plate 1. Two connecting plates 15 are disposed between the mounting plate 3 and the fixing plate 2. Pressure blocks 16 are fixedly connected to one side of each connecting plate 15. A connecting frame 5, which is F-shaped, is fixedly mounted on one side of the mounting plate 3. Two placement slots 6 are formed on one side of the connecting frame 5, and the same slat body 7 is placed in each of the two placement slots 6. The two pressure blocks 16 face the two placement slots 6 respectively. The square plate 4 and the fixing plate 2 are respectively... The system includes a drive assembly and a test assembly. The drive assembly includes a motor 8 fixedly mounted on one side of a square plate 4. The output end of the motor 8 rotatably passes through the square plate 4 and the mounting plate 3 and is fixedly connected to a threaded rod 9. The other end of the threaded rod 9 is rotatably connected to one side of the fixed plate 2. A first synchronous wheel 10 is fixedly sleeved on the outside of the threaded rod 9. The mounting plate 3 has a circular hole, in which a threaded post 11 is installed. The two ends of the threaded post 11 are rotatably connected to the opposite sides of the fixed plate 2 and the square plate 4, respectively. A second synchronous wheel 12 is fixedly sleeved on the outside of the threaded post 11. The first synchronous pulley 10 shares the same synchronous belt 13. Both the threaded post 11 and the threaded rod 9 have sliders 14 threadedly fitted onto their outer sides. One side of each of the two connecting plates 15 is fixedly connected to one side of each slider 14. A motor 8 is installed so that when the curtain body 7 placed in the placement slot 6 needs to be fixed, the motor 8 is started, causing the threaded rod 9 to rotate counterclockwise. Because the first synchronous pulley 10 is fixedly fitted onto the outer side of the threaded rod 9, and the first synchronous pulley 10 and the second synchronous pulley 12 share the same synchronous belt 13, the meshing transmission of the synchronous belt 13... When the motor 8 is running, the second synchronous wheel 12 will synchronously drive the threaded column 11 connected to it to rotate counterclockwise, thereby causing the slider 14, which is threadedly connected to both the threaded rod 9 and the threaded column 11, to move the connecting plate 15 fixedly connected on one side toward the connecting frame 5. Since pressure blocks 16 are fixedly installed on one side of each of the two connecting plates 15 and face the two placement slots 6 respectively, as the motor 8 continues to run, the two pressure blocks 16 will enter the two placement slots 6, thereby clamping the two ends of the curtain body 7 tightly, thus effectively preventing the curtain body 7 from falling off during the bending test.
[0021] The other side of the two sliders 14 is fixedly connected to the same guide block 17. Two guide rods 18 are fixedly installed between the connecting frame 5 and the fixed plate 2. The guide block 17 is slidably sleeved on the two guide rods 18. By setting the guide block 17, when the two sliders 14 drive the connecting plate 15, which is fixedly connected on one side, to move, the guide block 17 can provide stable guidance and limiting function, so that the two pressure blocks 16 can be accurately inserted into the two placement slots 6.
[0022] The test assembly includes a fixed plate 2 with an electric push rod 19 fixedly installed on one side. The output end of the electric push rod 19 passes through the fixed plate 2 and is fixedly connected to a pressing plate 20. The pressing plate 20 is U-shaped and faces the curtain body 7. A pressure sensor 21 is fixedly connected to the inner wall of one side of the pressing plate 20. With the pressing plate 20 installed, after the curtain body 7 is fixed, starting the electric push rod 19 will drive the pressing plate 20 to move towards the curtain body 7. As the pressing plate 20 continues to press, the pressure sensor 21 fixedly connected inside the pressing plate 20 will also transmit the pressure data to the controller 22 in real time for recording. Since both ends of the curtain body 7 are firmly fixed before the bending test, the bending data of the curtain body 7 can be accurately tested.
[0023] A controller 22 is fixedly installed on one side of the fixed plate 2. The controller 22 is electrically connected to the motor 8, the electric push rod 19, and the pressure sensor 21. A protective cover 23 is fixedly installed on one side of the connecting frame 5. The protective cover 23 is frame-shaped. Because the controller 22 is electrically connected to the motor 8, the electric push rod 19, and the pressure sensor 21, the controller 22 can control the forward and reverse rotation of the motor 8, thereby achieving the pressing and releasing of the two pressure blocks 16. Secondly, it can also control the extension and retraction of the electric push rod 19. Finally, the pressure sensor 21 can transmit real-time data to the controller 22 for recording. By setting up the protective cover 23, the protective cover 23 can prevent the fragments generated when the curtain body 7 breaks during the test from injuring the staff nearby.
[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.
[0025] In use: Place both ends of the curtain slat body 7 to be bent into the two placement slots 6 respectively. Start the motor 8, which drives the threaded rod 9 to rotate counterclockwise. Since the first synchronous pulley 10 is fixedly sleeved on the outside of the threaded rod 9, and the first synchronous pulley 10 and the second synchronous pulley 12 are driven by the meshing of the synchronous belt 13, the second synchronous pulley 12 will drive the threaded column 11 to rotate counterclockwise synchronously. The slider 14, which is threadedly sleeved on the threaded rod 9 and the threaded column 11, will drive the fixedly connected connecting plate 15 to move towards the connecting frame 5 under the threaded transmission. As the motor 8 continues to run, the fixed... As the pressure block 16 of the connecting plate 15 gradually enters the placement groove 6, it forms a tight clamp on both ends of the curtain body 7, effectively preventing the curtain from falling off during the test. After the curtain body 7 is fixed, the electric push rod 19 is activated to push the extrusion plate 20 to apply pressure to the curtain. The pressure sensor 21 built into the extrusion plate 20 will collect pressure data in real time and transmit it to the controller 22 for recording. Since both ends of the curtain body 7 have been firmly fixed before the test, the device can accurately obtain the bending strength data of the curtain body 7, ensuring the accuracy and reliability of the test results.
