Description

Technical Field

[0001] This utility model relates to the field of rubber strip production and testing technology, specifically to a strength testing device for polymer nano-reinforced rubber strips after molding. Background Technology

[0002] Polymer nano-reinforced rubber strips have higher strength than ordinary rubber strips and are widely used in various fields. After the polymer nano-reinforced rubber strips are produced, their strength performance needs to be tested to determine whether they meet the standards. Current testing equipment is basically designed for individual rubber strips. The equipment clamps the two ends of the rubber strip and then performs a tensile test. However, since rubber strips are usually extruded and rolled, this testing equipment would need to cut a section from the rolled rubber strip before testing. This testing method is relatively cumbersome.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a strength testing device for polymer nano-reinforced rubber strips after molding. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a strength testing device for polymer nano-reinforced rubber strips after molding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polymer nano-reinforced rubber strip strength testing device after molding, comprising a base, a traction end, a clamping end, a tensile force measuring machine, and a moving structure. The clamping end clamps one end of the rubber strip, and the traction end is used to clamp and pull the other end of the rubber strip through the moving structure to create tension on the rubber strip. During tensioning, the tensile force is tested by the tensile force measuring machine. The clamping end includes a tray, on which a turntable is installed. A motor is installed inside the tray, and the drive end of the motor is connected to the turntable. A sleeve is installed on the turntable. Two symmetrical clamping plates are also installed on the tray, and each clamping plate is connected to a cylinder.

[0006] Furthermore, the structure of the traction end and the clamping end is the same, also including a tray, a turntable is installed on the tray, a motor is installed inside the tray, the drive end of the motor is connected to the turntable, a sleeve is installed on the turntable, and two symmetrical clamping plates are also installed on the tray, with cylinders connected to the two clamping plates respectively.

[0007] Furthermore, the sleeve is composed of a circular array of several uprights, all of which are fixed on a turntable.

[0008] Furthermore, the movable structure includes a ball screw mounted on the base, a slide table slidably connected to the ball screw, and a carriage mounted on the base. The tensile force measuring machine is mounted on the slide table, and the tensile force measuring machine is slidably connected to the traction end and the traction end is slidably connected to the carriage.

[0009] Furthermore, the clamping end is mounted on the base via a raised platform, and the clamping end and the traction end are at the same horizontal height.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the testing equipment in this utility model can directly test from the rolled rubber strip without cutting a section in advance for testing. At the same time, it can test each section of the rolled rubber strip step by step. After the test is completed, the rubber strip is kept in a rolled shape, which can improve the testing efficiency.

[0017] 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.

[0018] This utility model provides a technical solution:

[0019] Please see Figure 1-4 A strength testing device for polymer nano-reinforced rubber strips after molding includes a base 1, a traction end 2, a clamping end 3, a tensile force measuring machine 7, and a moving structure. The clamping end 3 holds one end of the rubber strip, while the traction end 2 clamps and pulls the other end of the rubber strip via the moving structure, creating tension on the rubber strip. During tensioning, the tensile force measuring machine 7 tests the tensile force. The structure described above is basically consistent with the structural principle of existing technologies, except that:

[0020] The clamping end 3 includes a tray 8, on which a turntable 9 is mounted. A motor is installed inside the tray 8, and the drive end of the motor is connected to the turntable 9. A sleeve 10 is mounted on the turntable 9. Two symmetrical clamping plates 11 are also mounted on the tray 8. The two clamping plates 11 are respectively connected to cylinders 12, so that the rolled rubber strip can be directly sleeved on the sleeve 10. It is only necessary to pull the front end of the rubber strip roll over so that the traction end 2 can clamp it. During the test, the drive motor of the ball screw 14 drives the ball screw 14 to run, so that the slide table 4, which is slidably connected to the ball screw 14, slides. When the slide table 4 slides, the traction end 2 slides through the tensile force measuring machine 7, thereby pulling the rubber strip. During the pulling, the tensile force is displayed by the tensile force measuring machine 7. The slide frame 6 is supported by an L-shaped support rod 5. The slide frame 6 is staggered from the ball screw 14 so that the slide table 4 and the slide frame 6 do not interfere with each other when sliding. The tray 8 of the traction end 2 is sleeved on the slide frame 6 by the sliders on both sides of it.

[0021] To ensure the accuracy of the test results, sometimes every segment of the rubber strip in the whole roll is tested. Therefore, the structure of the traction end 2 and the clamping end 3 is the same, including the tray 8. A turntable 9 is installed on the tray 8, and a motor is installed inside the tray 8. The drive end of the motor is connected to the turntable 9. A sleeve 10 is installed on the turntable 9. Two symmetrical clamping plates 11 are also installed on the tray 8. The two clamping plates 11 are respectively connected to cylinders 12. Then the clamping end 3 unwinds the rubber strip, and the traction end 2 winds the rubber strip.

[0022] The two pairs of clamps 11 on the left and right sides will clamp the rubber strip during the test. The sleeve 10 is composed of a ring array of several uprights. The uprights are fixed on the turntable 9. The purpose is to allow the ends of the rubber strip to be quickly wrapped between the uprights when it is rolled up. An additional fixing structure between the ends of the rubber strip and the sleeve 10 is required.

[0023] Specifically: The moving structure includes a ball screw 14 mounted on the base 1, a slide 4 slidably connected to the ball screw 14, and a carriage 6 mounted on the base 1. The tensile force measuring machine 7 is mounted on the slide 4, and the tensile force measuring machine 7 is slidably connected to the traction end 2, and the traction end 2 is slidably connected to the carriage 6.

[0024] Specifically: the clamping end 3 is mounted on the base 1 via the raised platform 13, and the clamping end 3 and the traction end 2 are at the same horizontal height.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
