Description

Technical Field

[0001] This utility model belongs to the field of pultrusion equipment technology, and specifically relates to a yarn rack for composite material pultrusion production. Background Technology

[0002] In the pultrusion molding process of composite materials, the yarn rack is a key piece of equipment for storing and guiding reinforcing fibers. Its performance directly affects production efficiency and product quality. Common yarn rack structures are relatively fixed and have a single function, usually only meeting the basic needs of storing and guiding yarns.

[0003] Traditional yarn racks are limited by their fixed structure, making it difficult to flexibly expand the number of yarns and place spare yarns according to production needs. This lack of adaptability increases downtime. To solve these problems, we provide a yarn rack for composite material pultrusion production. Utility Model Content

[0004] The purpose of this invention is to provide a yarn rack for composite material pultrusion production, in order to solve the problems mentioned in the background art, where traditional yarn racks are limited by a fixed structure, making it difficult to flexibly expand the number of yarns and place spare yarns according to production needs, resulting in insufficient adaptability and increased downtime.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn rack for pultrusion production of composite materials, comprising a frame, a shelf fixedly connected inside the frame, a sleeve fixedly connected to the bottom of the shelf, an extension rod slidably sleeved at both ends of the sleeve, an installation groove provided at the top of the extension rod, a rotating block rotatably connected inside the installation groove, a support rod fixedly connected to the top of the rotating block, support plates rotatably connected to both sides of the rotating block, a limiting groove adapted to the support plate provided at the top of the extension rod, a through groove adapted to the extension rod provided inside the frame, and a positioning rod fixedly connected to the top of the shelf.

[0006] Preferably, one end of the extension rod is fixedly connected to a housing, and two limiting rods are slidably connected inside the housing. A spring is provided inside the housing, and the two ends of the spring are respectively sleeved with the limiting rods.

[0007] Preferably, the sleeve has fixing holes on both sides that are adapted to the limiting rod, and the sleeve has limiting holes on both sides that are adapted to the limiting rod.

[0008] Preferably, one end of the extension rod is provided with a pull ring, and one end of the pull ring is threadedly connected to the extension rod.

[0009] Preferably, a threading plate is fixedly connected inside the frame, and the threading plate has threading holes inside.

[0010] Preferably, the bottom of the frame is bolted with casters, and the casters are equipped with locking devices.

[0011] This utility model has the following beneficial effects: This device allows the expansion rod to slide smoothly within the sleeve by pressing the limiting rod to compress the spring and pulling the pull ring after placing the yarn on the top of the shelf and positioning it with the positioning rod. When the spring returns to its original position, the limiting rod automatically engages with the limiting hole to fix its position. At the same time, the support rod can drive the rotating block to rotate, causing the support plate to rotate into the limiting groove to form a stable support structure, which facilitates the placement of spare yarn. This achieves effective support for spare yarn and convenient expansion of the number of yarns. It also allows the yarn tail end to be pre-connected to the spare yarn head end during production, which significantly improves the convenience of yarn splicing and production efficiency, reduces equipment downtime, and has the advantages of simple operation, strong adaptability, and outstanding practicality.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example 1: refer to Figure 1-5A yarn rack for pultrusion production of composite materials includes a frame 1, a shelf 2 fixedly connected inside the frame 1, a sleeve 3 fixedly connected to the bottom of the shelf 2, an extension rod 4 slidably sleeved at both ends of the sleeve 3, an installation groove 5 opened at the top of the extension rod 4, a rotating block 6 rotatably connected inside the installation groove 5, a support rod 7 fixedly connected to the top of the rotating block 6, support plates 8 rotatably connected to both sides of the rotating block 6, a limiting groove 9 adapted to the support plate 8 opened at the top of the extension rod 4, a through groove 10 adapted to the extension rod 4 opened inside the frame 1, and a positioning rod 19 fixedly connected to the top of the shelf 2.

[0016] Specifically, this device places the yarn on top of the shelf 2 and positions it via the positioning rod 19. By pressing the limiting rod 12 to compress the spring 13 and pulling the pull ring 16, the expansion rod 4 can slide smoothly within the sleeve 3. When the spring 13 returns to its original position, the limiting rod 12 automatically engages with the limiting hole 15 to fix its position. At the same time, the support rod 7 can drive the rotating block 6 to rotate, causing the support plate 8 to rotate into the limiting groove 9 to form a stable support structure, which facilitates the placement of spare yarn. This achieves effective support for spare yarn and convenient expansion of the number of yarns. It also allows the yarn tail end to be pre-connected to the spare yarn head end during production, significantly improving the convenience of yarn splicing and production efficiency, reducing equipment downtime, and has the advantages of simple operation, strong adaptability, and outstanding practicality.

[0017] refer to Figure 4 One end of the extension rod 4 is fixedly connected to the housing 11. Two limiting rods 12 are slidably connected inside the housing 11. A spring 13 is provided inside the housing 11. The two ends of the spring 13 are respectively sleeved with the limiting rods 12. By setting the limiting rods 12, the extension rod 4 can be limited and fixed in conjunction with the limiting hole 15 and the fixing hole 14.

[0018] refer to Figure 3 Both sides of the sleeve 3 are provided with fixing holes 14 that are compatible with the limiting rod 12, and both sides of the sleeve 3 are provided with limiting holes 15 that are compatible with the limiting rod 12. By setting the limiting holes 15 and fixing holes 14, it can be used in conjunction with the limiting rod 12.

[0019] refer to Figure 2 One end of the extension rod 4 is provided with a pull ring 16, and one end of the pull ring 16 is threadedly connected to the extension rod 4. By providing the pull ring 16, the extension rod 4 can be easily pulled.

[0020] refer to Figure 5 The frame 1 is fixedly connected to a yarn threading plate 17. The yarn threading plate 17 has a yarn threading hole 18 inside. By setting the yarn threading plate 17 and the yarn threading hole 18, the yarn can be combed.

[0021] refer to Figure 1The bottom of the frame 1 is bolted with casters 20, which are equipped with locking devices. By setting the casters 20, the device can be moved easily.

[0022] Brief description of usage: The user can place the yarn on the top of the shelf 2 and position it using the positioning rod 19. Then, press the limiting rod 12 to slide inside the housing 11, while the limiting rod 12 compresses the spring 13. Then, pull the pull ring 16 to drive the expansion rod 4 to slide inside the sleeve 3. The spring 13 resets and drives the limiting rod 12 to engage inside the limiting hole 15. Then, pull the support rod 7 to drive the rotating block 6 to rotate. Then, rotate the support plate 8 to engage inside the limiting groove 9. Place the spare yarn on the surface of the support rod 7. The yarn is supported by the support plate 8 and the expansion rod 4. Then, the tail end of the yarn can be connected to the head end of the spare yarn, thereby enabling the placement of spare yarn and the expansion of the yarn quantity.
