[0003] In the tensile coefficient detection process of the plastic product detection, the worker needs to first put the plastic product to be detected into the detector, the detector clamps and fixes the plastic product, rotates the lead screw by using the motor to pull the plastic product and record the pulling force, and the detector displays the pulling force data after the detection, so that the worker can detect the tensile coefficient of the plastic product.
[0004] The prior art in the above has the following defects: when the pulling force of different plastic products is tested, the worker needs to control the stretching speed and stretching range according to the test standard, and it is inconvenient to detect the tensile coefficient of a plurality of plastic products. CONTENT OF THE INVENTION

[0008] By adopting the above technical solution, when the tensile testing device moves along the drive screw, the baffle can limit the tensile testing device, ensuring that the tensile testing device slides smoothly on the base. The two ends of the plastic product to be tested are respectively clamped in the two clamping components. The testing instrument body sets the tensile speed and tensile range according to the plastic product to be tested. The distance sensor transmits the distance between the two clamping blocks to the testing instrument body in real time, ensuring that the testing instrument controls the tensile speed and tensile range according to the different plastic products to be tested.

[0017] Optionally, one end of both the drive screw and the slide bar is connected to the fixed block.
[0018] By adopting the above technical solution, the stability of the tensile testing device when sliding on the base can be increased, ensuring that the tensile testing device can move smoothly when the drive screw rotates.
[0019] Optionally, a cover plate is slidably disposed on the baffle, and the cover plate is located between the tensile force detection device and the fixing block.
[0020] By adopting the above technical solution, it is possible to prevent broken plastic products from falling onto the base, ensuring that the tensile testing device can move smoothly on the base.
[0021] Optionally, the base is threaded with feet at the bottom.
[0022] By adopting the above technical solution, the testing instrument can be placed stably, which facilitates the staff to test the tensile coefficient of plastic products.
[0023] In summary, this application has the following technical effects:

[0025] 2. By setting up a bidirectional lead screw, slider and clamping block, the two clamping blocks can move simultaneously, which makes it easy for the staff to fix the plastic product to be tested, and at the same time can ensure that the clamping components can firmly clamp the plastic product to be tested.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses a tensile strength tester for plastic products, referring to... Figure 1 and Figure 2 The tensile coefficient tester includes a base 1, which is rectangular. One end of the base 1 is bolted to a fixed block 2, and the other end of the base 1 is fitted with the tester body 3. Two baffles 4 are bolted to the edges of the top surface of the base 1 along its length. The two ends of the baffles 4 abut against the fixed block 2 and the tester body 3, respectively. A tensile testing device 5 is slidably mounted on the base 1, with its sidewalls abutting against the two baffles 4 on opposite sides. A motor 6 is installed inside the tester body 3. The output shaft of the machine 6 is connected to a reduction gearbox 61 via a coupling. The side of the reduction gearbox 61 away from the motor 6 is connected to a drive screw 7 via a coupling. The end of the drive screw 7 away from the reduction gearbox 61 passes through the tensile testing device 5 and is rotatably connected to the fixed block 2. The drive screw 7 is threadedly connected to the tensile testing device 5. Clamping components 8 are provided on the opposite side of the tensile testing device 5 and the fixed block 2. A distance sensor 9 is installed on the top of the fixed block 2. The tensile testing device 5, the motor 6 and the distance sensor 9 are all electrically connected to the main body of the testing instrument 3.
[0033] When using this tensile coefficient tester, the motor 6 is controlled to rotate by the tester body 3. The power output of the motor 6 is transmitted to the drive screw 7 through the reduction gearbox 61. The reduction gearbox 61, through its internal gear transmission mechanism, can reduce the high speed of the motor 6 to the speed required by the drive screw 7 to adapt to different tensile speeds. The rotation of the drive screw 7 will drive the tensile testing device 5 to move. When the tensile testing device 5 moves along the drive screw 7, the baffle 4 can limit the tensile testing device 5 to ensure that the tensile testing device 5 slides smoothly on the base 1. The two ends of the plastic product to be tested are clamped in the two clamping components 8 respectively. The tester body 3 sets the tensile speed and tensile range according to the plastic product to be tested. The distance sensor 9 transmits the distance between the two clamping blocks 85 to the tester body 3 in real time, ensuring that the tester can control the tensile speed and tensile range according to the different plastic products to be tested. This simplifies the operation steps for staff to measure the tensile coefficient of different plastic products and facilitates the tensile coefficient testing of various plastic products.
[0034] Reference Figure 2 and Figure 3 The clamping assembly 8 includes a base 81, in which a bidirectional lead screw 82 is rotatably mounted. One end of the bidirectional lead screw 82 extends out of the top of the base 81 and is welded with a handwheel 83. A sliding groove is provided on one side wall of the base 81, and a slider 84 is slidably mounted in the sliding groove. The slider 84 is sleeved on the bidirectional lead screw 82 and threadedly connected to the bidirectional lead screw 82. Two sliders 84 are provided and are respectively located on two threaded sections of the bidirectional lead screw 82. A clamping block 85 is provided on the section of the slider 84 away from the base 81, and the clamping block 85 is located on the opposite side of the two sliders 84.
[0035] When using this tensile coefficient tester, turning the handwheel 83 causes the bidirectional lead screw 82 to rotate. The bidirectional lead screw 82 drives the two sliders 84 to move towards or away from each other in the slide groove, which in turn drives the two clamping blocks 85 to clamp or release the plastic product to be tested. The rotation of the bidirectional lead screw 82 can make the two clamping blocks 85 move simultaneously, which makes it easier for the staff to fix the plastic product to be tested, and at the same time ensures that the clamping assembly 8 firmly clamps the plastic product to be tested.
[0036] Reference Figure 3 Both sliders 84 have mounting grooves 86 on opposite sides, with the sidewalls of the mounting grooves 86 inclined towards the bottom. The clamping block 85 has a mounting block 87 machined on the side facing the slider 84 to mate with the mounting groove 86. When using this tensile coefficient tester, the mounting block 87 can slide within the mounting groove 86, facilitating the removal and cleaning of the clamping block 85. Operators can replace different clamping blocks 85 according to the characteristics of different plastic products, making it convenient to test the tensile coefficient of various plastic products.
[0037] Reference Figure 2 A sliding rod 10 connects the main body 3 of the testing instrument and the fixed block 2. Two sliding rods 10 are provided, both parallel to the length direction of the drive screw 7, and located on opposite sides of the drive screw 7. The sliding rods 10 pass through the tensile testing device 5 and are slidably connected to it. When using this tensile coefficient testing instrument, the sliding rods 10 increase the stability of the tensile testing device 5 as it slides on the base 1, ensuring smooth movement of the tensile testing device 5 when the drive screw 7 rotates.
[0038] Reference Figure 1A cover plate 11 is slidably mounted on the top of the baffle 4. In this embodiment, the cover plate 11 is a retractable sealing cover plate, located between the two baffles 4. Two cover plates 11 are provided. One cover plate 11 is fixed at both ends to the tensile testing device 5 and the fixing block 2 facing each other by bolts. The other cover plate 11 is fixed to the tensile testing device 5 and the testing instrument body 3 facing each other by bolts. When this tensile coefficient tester is used, the cover plate 11 can prevent broken plastic products from falling onto the base 1, ensuring that the tensile testing device 5 can move smoothly on the base 1.
[0039] Reference Figure 1 and Figure 2 The base 1 has four threaded feet 12 at its bottom corners. When using this tensile strength tester, the length of the feet 12 inserted into the base 1 can be adjusted according to the placement of the tester to ensure stable placement of the tester and facilitate the tensile strength testing of plastic products by the staff.
