Description

Technical Field

[0001] This utility model relates to the field of guide plate technology, specifically a guide plate for polyester industrial yarn. Background Technology

[0002] Polyester industrial yarn is a high-strength polyester industrial filament. As an important industrial textile material, it is widely used in tire cord, conveyor belts, canvas and other fields. In the production process of polyester industrial yarn, the guide plate is a key component in the spinning, drawing and winding processes. Its function is to accurately position and guide the yarn in operation, prevent the yarn from tangling or abrading, and ensure production stability and product quality. Currently, most common wire guide plates on the market consist of multiple wire guide wheels directly fixed to a single wire guide rod with bolts, resulting in an unadjustable spacing. To address this, some improved designs have emerged, such as designing the wire guide wheels to slide on the guide rod's slide rails and fix their positions with locking screws. While this design solves the spacing adjustment problem, when a middle wire guide wheel in the production line needs replacement due to long-term wear, the operator must disassemble multiple adjacent wire guide wheels in sequence before removing the damaged wire guide wheel from one end of the guide rod. This process is cumbersome, time-consuming, and affects equipment maintenance efficiency. Utility Model Content

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-4 In this embodiment of the present invention, a guide plate for polyester industrial yarn includes a guide wheel 100 and a guide rod 200, and further includes a mounting frame 300 for mounting the guide wheel 100 and a support base 400 for supporting the entire device. The mounting frame 300 includes a left frame 310 and a right frame 320. The left frame 310 includes a U-shaped seat 311 that engages with the guide rod 200. A side plate 312 is fixedly connected to the bottom surface of the U-shaped seat 311. The right frame 320... The device includes a U-shaped seat 321 that engages with the guide rod 200. The top of the U-shaped seat 321 has a threaded hole. The bottom surface of the U-shaped seat 321 is fixedly connected to a side plate 322. The inner wall of the side plate 322 is fixedly connected to a plug post 323 that is rotatably connected to the guide wheel 100. The top of the U-shaped seat 311 is rotatably connected to a top plate 330. The top surface of the top plate 330 is screwed with a wing bolt 331 that matches the threaded hole at the top of the U-shaped seat 321.

[0016] Specifically, by rotating the top plate 330 to cover the right side frame 320 and parallel to the guide rod 200, and tightening the wing bolt 331, the guide wheel 100 can be installed on the guide rod 200 using the mounting bracket 300. When a guide wheel 100 is worn and needs to be replaced, simply loosen the wing bolt 331 to separate the left side frame 310 and the right side frame 320, thereby removing the worn guide wheel 100 from the insertion post 323, achieving quick connection and fixation of the guide wheel 100.

[0017] Example 1 like Figure 2-3 As shown, in this embodiment, the top surface of the guide rod 200 is provided with a plurality of limiting grooves 210 at equal intervals, the top surface of the top plate 330 is provided with a pull ring 334, the bottom surface of the pull ring 334 is fixed with a connecting rod 332 that penetrates and inserts into the top plate 330, the bottom end of the connecting rod 332 is fixedly connected with a limiting block 333 that is inserted and cooperates with the limiting groove 210, and the outer wall of the connecting rod 332 is sleeved with a reset spring 335.

[0018] In this embodiment, after U-shaped seat 311 and U-shaped seat 321 are engaged with the guide rod 200, the limiting block 333 will remain inserted into the limiting groove 210 of the guide rod 200 under the preload of the reset spring 335. At this time, the position of the mounting bracket 300 and the guide wheel 100 below it is fixed, preventing the mounting bracket 300 from moving horizontally during processing. When it is necessary to adjust the position of the guide wheel 100, simply lift the pull ring 334 upwards to drive the limiting block 333 to overcome the spring force and exit from the limiting groove 210. The mounting bracket 300 can then slide freely along the guide rod 200. After adjustment, release the pull ring 334, and the limiting block 333 will automatically engage in the new limiting groove 210 under the push of the reset spring 335, completing the positioning.

[0019] like Figure 1 As shown, in this embodiment, the support base 400 includes a base 410, and an outer sleeve 420 is symmetrically fixed on the top surface of the base 410. The top ends of the two outer sleeves 420 are slidably inserted with inner rods 430, and the two ends of the guide rod 200 are respectively fixedly connected to the top sides of the two inner rods 430.

[0020] In practice, by adjusting the insertion depth of the inner rod 430 in the outer tube 420, the installation height of the entire wire guide plate can be flexibly adjusted to adapt to different production equipment and process requirements. After determining the height, the fastening knob can be used to lock the relative position of the inner rod 430 and the outer tube 420 through the corresponding adjustment hole to ensure the stability of the support.

[0021] Example 2 Based on Embodiment 1, in order to further enhance the connection strength between the left side frame 310 and the right side frame 320.

[0022] like Figure 4 As shown, in this embodiment, a plug rod 313 is fixedly connected to the inner wall of the side plate 312. A locking block 314 is symmetrically arranged inside the plug rod 313. A return spring 315 is fixedly connected between the two locking blocks 314. A plug groove 3231 is provided at the end of the plug post 323 to engage with the plug rod 313. A locking groove 3232 is provided inside the plug groove 3231 to engage with the corresponding locking block 314. A threaded rod 316 is screwed onto the outer wall of the side plate 312. A tapered head 317 is fixedly connected to the end of the threaded rod 316 located inside the plug rod 313.

[0023] In practice, after the guide wheel 100 is fitted onto the insertion post 323, the U-shaped seat 321 is inserted from bottom to top onto the guide rod 200. Then, it is moved horizontally along the outer wall of the guide rod 200, bringing the right side frame 320 closer to its mating left side frame 310, until the insertion rod 313 is inserted into the insertion slot 3231. The top plate 330 is rotated to cover the top of the U-shaped seat 321, and the wing bolt 331 is tightened to fix the U-shaped seat 311 and the U-shaped seat 321 together. Then, the threaded rod 316 is rotated, causing the conical head 317 to approach the locking block 314 and abut against the inclined surface between the two locking blocks 314. As the threaded rod 316 continues to screw in, the conical head 317 forces the two locking blocks 314 together. The locking block 314 expands outward against the preload of the return spring 315 and finally locks into the locking groove 3232 on the plug post 323. At this time, the left frame 310 and the right frame 320 are firmly locked together to form a rigid whole. When the guide wheel 100 needs to be replaced, the threaded rod 316 is loosened in the opposite direction to make it exit outward. As the conical head 317 is pulled back, the preload of the return spring 315 is released, driving the two locking blocks 314 to move closer to each other and disengage from the locking groove 3232. Then, the wing bolt 331 is unscrewed, and the right frame 320 can slide away from the left frame 310 along the guide rod 200, so that the guide wheel 100 can be quickly removed from the plug post 323.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
