Description

Technical Field

[0001] This utility model relates to the field of synthetic fiber production technology, specifically to a synthetic fiber stretching machine with guiding and positioning function. Background Technology

[0002] The basic raw materials for synthetic fibers mainly come from petroleum. Synthetic fibers are made through chemical synthesis and have many superior properties compared to natural fibers, such as high strength, wear resistance, and acid and alkali resistance.

[0003] In synthetic fiber processing, the stretching machine is an important piece of equipment. It stretches fibers, and by controlling the stretching ratio and speed, the strength and elongation of the fibers can be significantly improved. This process involves an increase in the orientation of the fiber macromolecules along the fiber axis, resulting in a more compact fiber structure, stronger intermolecular forces, and ultimately enhanced mechanical properties.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The existing stretching machine has insufficient positioning function for synthetic fibers in daily operation, which makes it difficult for synthetic fibers to pass through the stretching machine stably and evenly during the stretching process, and even results in uneven stretching effect, leading to uneven strength, elasticity or thickness of the fibers; 2. The housing of the existing stretching machine is usually fixed by bolts. When the device is damaged, it is inconvenient for the user to quickly disassemble and assemble the device and maintain the internal parts, which affects the use of the device. Utility Model Content

A feed inlet is installed on one side surface of the housing, and a discharge outlet is installed on the other side surface of the housing. First fixing blocks are installed on both sides of the outer wall of the housing. A guiding assembly is installed on the inner wall of the housing. A stretching roller is rotatably connected to the inner wall of the housing. A first motor is installed on one end of the stretching roller.

[0006] The guiding assembly includes a first limiting rail and a second limiting rail installed on the inner wall of the housing. A bidirectional screw is installed on the inner wall of the first limiting rail. A second motor is installed at one end of the bidirectional screw. A first slider is installed on the outside of the bidirectional screw. One end of a guide rod is installed on one side surface of the first slider. A second slider is installed at the other end of the guide rod. A positioning slide rod is installed on the inner wall of the second slider.

[0007] More preferably, there are four hydraulic push rods, and the hydraulic push rods are symmetrical about the central axis of the housing, and the hydraulic push rods and the housing constitute a lifting mechanism.

[0008] More preferably, the second motor forms a transmission mechanism with the first slider via a bidirectional screw, and there are two of each of the first slider, the guide rod, and the second slider.

[0009] More preferably, the second slider and the positioning slider form a sliding mechanism.

[0010] More preferably, the positioning rod is located at the four corners of the side cover, and a positioning hole with an internal size structure that matches the external size structure of the positioning rod is opened on one side surface of the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention employs a design that facilitates guidance and positioning.

The first fixing block and the second fixing block fit together, and the handle can be rotated to drive the one-way screw to rotate and insert into the threaded hole, which can quickly fix the side cover and the housing. Conversely, the side cover can be quickly disassembled, which is convenient for internal maintenance of the device. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a synthetic fiber stretching machine with guiding and positioning function, including a housing 1, a hydraulic push rod 2 with one end mounted on the bottom surface of the housing 1, a support base 3 with the other end mounted on the hydraulic push rod 2, a feed inlet 4 with one side surface of the housing 1, a discharge outlet 5 with the other side surface of the housing 1, first fixing blocks 6 with both sides of the outer wall of the housing 1, a guide assembly 7 with the inner wall of the housing 1, a stretching roller 8 rotatably connected to the inner wall of the housing 1, a first motor 9 with one end of the stretching roller 8, a side cover 10 with one side surface of the housing 1, second fixing blocks 11 with both sides of the outer wall of the side cover 10, a one-way screw 12 with the inner wall of the second fixing block 11, a handle 13 with one side surface of the one-way screw 12, a positioning rod 14 with one side surface of the side cover 10, and a bearing 15 with the inner wall of the side cover 10.

[0023] The guide assembly 7 includes a first limiting rail 701 and a second limiting rail 702 installed on the inner wall of the housing 1. A bidirectional screw 703 is installed on the inner wall of the first limiting rail 701. A second motor 704 is installed at one end of the bidirectional screw 703. A first slider 705 is installed on the outside of the bidirectional screw 703. One end of a guide rod 706 is installed on one side surface of the first slider 705. A second slider 707 is installed at the other end of the guide rod 706. A positioning slide rod 708 is installed on the inner wall of the second slider 707.

[0024] In this embodiment, as Figure 1 As shown, there are four hydraulic push rods 2, and the hydraulic push rods 2 are symmetrical about the central axis of the housing 1. The hydraulic push rods 2 and the housing 1 form a lifting mechanism. With this design, the height of the housing 1 can be adjusted by activating the hydraulic push rods 2, so that the equipment has the function of height adjustment.

[0025] In this embodiment, as Figure 4 As shown, the second motor 704 forms a transmission mechanism with the first slider 705 via a bidirectional screw 703, and there are two of each of the first slider 705, guide rod 706, and second slider 707. With this design, the second motor 704 can be started to drive the bidirectional screw 703 to rotate, causing the first sliders 705 to move closer together, and the guide rods 706 to move closer together. According to the needs of the synthetic fiber, the two sides of the synthetic fiber are positioned and guided, thereby guiding the direction of the synthetic fiber and preventing the synthetic fiber from deviating from the correct trajectory during the stretching process.

[0026] In this embodiment, as Figure 4 As shown, the second slider 707 and the positioning slider 708 constitute a sliding mechanism. With this design, when the guide rods 706 come together, they will drive the second slider 707 to slide on the outer wall of the positioning slider 708. The positioning slider 708 can effectively position the movement of the guide rods 706 and prevent the guide rods 706 from deviating.

[0027] In this embodiment, as Figure 3 As shown, the positioning rod 14 is located at the four corners of the side cover 10, and a positioning hole with an internal dimension structure that matches the external dimension structure of the positioning rod 14 is opened on one side surface of the housing 1. With this design, when the user installs the side cover 10 to the housing 1, the side cover 10 can be positioned by the positioning rod 14 and the positioning hole. At this time, the bearing 15 is in contact with the tension roller 8, which can effectively improve the installation accuracy and thus improve the installation efficiency.

[0028] In this embodiment, as Figure 3 As shown, a sealing ring is provided on one side surface of the side cover 10; with this design, when the side cover 10 is installed with the housing 1, the sealing ring can fill the gap between the side cover 10 and the housing 1, effectively improving the sealing performance of the device.

[0029] In this embodiment, as Figure 2 As shown, the inner wall of the first fixing block 6 has a threaded hole with an internal size structure that matches the external size structure of the one-way screw 12, and the handle 13 and the one-way screw 12 form a screw transmission mechanism. With this design, when the side cover 10 is inserted and installed into the housing 1 through the positioning rod 14, the first fixing block 6 and the second fixing block 11 are in contact. The handle 13 can be rotated to drive the one-way screw 12 to rotate and insert into the threaded hole, which can quickly fix the side cover 10 and the housing 1. Conversely, the side cover 10 can be quickly disassembled.

[0030] The method of use and advantages of this utility model: The synthetic fiber stretching machine with guiding and positioning function operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, according to production needs, the hydraulic push rod 2 is activated to adjust the height of the housing 1. Then, one end of the synthetic fiber is passed through the feed port 4, the stretching roller 8, and the discharge port 5 in sequence. At this time, the synthetic fiber is located between the guide rods 706. The second motor 704 is activated to drive the bidirectional screw 703 to rotate, causing the first sliders 705 to move closer together, and the guide rods 706 to move closer together. According to the needs of the synthetic fiber, the two sides of the synthetic fiber are positioned and guided. Then, the first motor 9 is activated to drive the stretching roller 8 to rotate and stretch the synthetic fiber. If internal maintenance of the device is required, the handle 13 can be rotated to drive the unidirectional screw 12 to rotate, so that the unidirectional screw 12 is pulled out from the threaded hole of the first fixing block 6. Then, the side cover 10 is pulled out from the positioning hole of the housing 1 through the positioning rod 14. At this time, the side cover 10 is separated from the housing 1, and the internal maintenance of the device can be performed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
