Description

Technical Field

[0001] The utility model relates to the technical field of polyester industrial yarns, in particular to a stretching device for industrial yarn production. Background Art

[0002] Polyester industrial yarn refers to polyester yarn used for industrial purposes, which is characterized by high strength, thick denier, and a fineness of not less than 550 detx. Due to the characteristics of high strength, high modulus, anti-aging, and good impact resistance, it is widely used in geotechnical materials, automobiles, tire cord fabrics, conveyor belts, advertising light box fabrics, and other fields. After the production of polyester industrial yarn is completed, a stretching test needs to be carried out to determine whether the industrial yarn meets the production standards.

[0003] However, the existing industrial yarn stretching devices may have the following problems: 1. When installing and disassembling the industrial yarn, multiple screws need to be tightened, which is rather troublesome and affects the test efficiency; 2. After the industrial yarn is fixed, there is no guiding for the industrial yarn, resulting in an angle between the industrial yarn and the stretching force, thus affecting the test results. In view of the above problems, a stretching device for industrial yarn production is proposed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a stretching device for industrial yarn production, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stretching device for industrial yarn production includes a bottom plate. Two support plates are fixedly installed at the upper end of the bottom plate. A top plate is fixedly installed jointly at the upper ends of the support plates. A first hydraulic cylinder is fixedly installed at the lower end of the top plate. The output end of the first hydraulic cylinder is fixedly connected to a first trapezoidal block. The first trapezoidal block is fixedly connected to a first mounting plate. A first clamping device is installed at one end of the first mounting plate. A second hydraulic cylinder is fixedly installed at the upper end of the bottom plate. The output end of the second hydraulic cylinder is fixedly connected to a second trapezoidal block. The second trapezoidal block is fixedly connected to a second mounting plate. A second clamping device is fixedly installed at one end of the second mounting plate. An industrial yarn is jointly connected between the first clamping device and the second clamping device.

[0007] The first clamping device includes a waist-shaped block which is fixedly installed at the upper end of the first mounting plate. A guiding groove is formed at the lower end of the waist-shaped block, and a rectangular groove is formed at the upper end of the first mounting plate. A clamping block is installed in the rectangular groove. A first cylindrical groove is formed at the right end of the clamping block, and a limiting groove is formed in the first cylindrical groove. The first cylindrical groove communicates with the limiting groove. A second cylindrical groove is formed on the right inner wall of the rectangular groove, and a reset post is fixedly installed in the second cylindrical groove. A reset spring is sleeved on the circumferential surface of the reset post. The left end of the reset spring is fixedly connected to the limiting groove, and the right end of the reset spring is fixedly connected to the second cylindrical groove. An eccentric wheel is hinged to one end of the first mounting plate, and a handle is fixedly connected to the circumferential surface of the eccentric wheel. A plurality of cylindrical grooves are formed at one end of the first mounting plate, and locking posts are inserted into the cylindrical grooves. When clamping industrial wires with different diameters, the locking posts can be inserted into the cylindrical grooves at different positions, and the locking posts abut against the handle on the eccentric wheel, so as to lock the eccentric wheel and ensure the reliability of clamping.

[0008] Preferably, the first clamping device and the second clamping device have the same structure.

[0009] Preferably, the shape and size of the clamping block are adapted to the rectangular groove, and the clamping block is in sliding fit with the rectangular groove.

[0010] Preferably, the positions of the first clamping device and the second clamping device correspond to each other vertically.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By providing a clamping device, when installing an industrial wire, first wind one end of the industrial wire in the guiding groove of the waist-shaped block, and make the industrial wire fit the waist-shaped block and the first mounting plate. Then rotate the handle to make the eccentric wheel push the clamping block in the rectangular groove to slide and press the industrial wire. Then clamp the other end of the industrial wire through the second clamping device to complete the installation of the industrial wire. Then start the first hydraulic cylinder to make the first clamping device move upward to conduct a tensile test on the industrial wire. After the tensile test is completed, rotate the handle, the eccentric wheel no longer presses the clamping block, and the clamping block slides in the rectangular groove under the pulling force of the reset spring until the reset post abuts against the limiting groove, so that the tested industrial wire can be drawn out to complete the tensile test of the industrial wire.

[0015] 2. By providing a guiding groove at one end of the waist-shaped block, the industrial wire can be closely attached to the guiding groove during installation, making the industrial wire in a vertical state, so that it does not form an angle with the tensile force, improving the accuracy of the tensile test results.

[0016] 3. By fixedly installing a second hydraulic cylinder at the upper end of the bottom plate, the height of the second clamping device can be controlled, so that tensile tests can be carried out on industrial wires of different lengths, improving the application range of the device.
