Description

Technical Field

[0001] The utility model relates to the technical field of fiberglass sand-filled pipe production, and particularly relates to a fiberglass sand-filled pipe yarn guiding device. Background Technique

[0002] The fiberglass sand-filled pipe is a new composite material made of resin as the matrix material, glass fiber and its products as the reinforcing material, and quartz sand as the filling material. With its excellent corrosion resistance, hydraulic characteristics, light weight and high strength, large conveying flow rate, convenient installation, short construction period and low comprehensive investment, it has become the best choice for the chemical industry, drainage projects and pipeline projects.

[0003] During the production and processing of fiberglass sand-filled pipes, the glass fiber yarn is transported to the surface of the winding machine through a yarn guiding device, so that the glass fiber yarn is wound on the surface of the winding machine. While the glass fiber yarn is being wound, the resin matrix, glass fiber and quartz sand are wrapped inside the glass fiber yarn to form a preliminary fiberglass sand-filled pipe. Then, the surface of the wound glass fiber yarn is pressed by a pressing roller to fasten the inside of the fiberglass sand-filled pipe and discharge the excess air bubbles. The whole fiberglass sand-filled pipe is cured and shaped by a dryer, and finally the finished fiberglass sand-filled pipe is obtained. However, when the existing yarn guiding device transports the glass fiber yarn to the surface of the winding machine for winding, it cannot perform pre-coating fat treatment on the glass fiber yarn, resulting in that when the glass fiber yarn wraps the resin matrix, glass fiber and quartz sand, it is difficult for the glass fiber yarn to be completely mixed with the liquid resin matrix in a short time, and "resin overflow" will occur at the gap between adjacent glass fiber yarns, causing waste of the liquid resin matrix, increasing the production cost, and at the same time, dust and other impurities will remain on the surface of the glass fiber yarn, resulting in more air bubbles when the glass fiber yarn contacts the liquid resin matrix, affecting the quality of the fiberglass sand-filled pipe. Therefore, there is an urgent need to provide a solution to improve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fiberglass sand-filled pipe yarn guiding device, which can perform pre-coating fat curing treatment and dust removal treatment on the glass fiber yarn, so as to form a closer combination between the subsequent glass fiber yarn and the resin matrix, prevent "resin overflow" from occurring at the gap between adjacent glass fiber yarns, effectively save the production cost, and at the same time reduce the air bubbles generated when the glass fiber yarn contacts the liquid resin matrix, ensuring the quality of the fiberglass sand-filled pipe.

[0005] A fiberglass sand-filled pipe yarn guiding device provided by the utility model adopts the following technical scheme: it includes a mounting frame, a plurality of yarn reels are arranged on the right side of the mounting frame, a yarn guiding roller is arranged on the mounting frame on the left side of the yarn reels, a dust removal roller and a pre-coating fat unit are arranged in sequence on the left side of the mounting frame where the yarn guiding roller is located, and the pre-coating fat unit is used for pre-coating fat curing treatment on the glass fiber yarn.

[0006] Optionally, a tensioning unit is provided between the yarn guiding roller and the yarn feeding disc on the mounting frame.

[0009] Optionally, the pre-coating grease unit includes a grease storage tank, a guiding roller, and a heater; the grease storage tank is installed on the mounting frame on the left side of the dust removing roller. A guiding roller is provided at the top and inside of the grease storage tank, and the guiding roller provided inside the grease storage tank is located below the liquid level of the liquid resin.

[0010] Optionally, a grease injection pipeline and a grease replacement pipeline are provided at the bottom of the grease storage tank.

[0011] Optionally, a heat conducting wire and a temperature sensor are installed at the bottom of the grease storage tank.

[0012] The beneficial effects of a glass fiber reinforced plastic sand-filled pipe yarn guiding device provided by the present utility model are as follows:

[0013] Through the cooperation of the dust removing roller and the pre-coating grease unit provided on the mounting frame, it is possible to perform pre-coating grease curing and dust removal treatment on the surface of the glass fiber yarn, so that a tighter combination is formed between the subsequent glass fiber yarn and the resin matrix, preventing the phenomenon of "resin overflow" at the gap between adjacent glass fiber yarns, avoiding the waste of the liquid resin matrix, effectively saving the production cost, and at the same time reducing the bubbles generated when the glass fiber yarn contacts the liquid resin matrix, ensuring the quality of the glass fiber reinforced plastic sand-filled pipe;

[0019] See Figure 1 , the embodiments of the present utility model provide a glass fiber reinforced plastic sand-filled pipe yarn guiding device, which includes a mounting frame 1. A plurality of yarn unwinding discs 2 are arranged on the right side of the mounting frame 1. A yarn guiding roller 3 is arranged on the left side of the mounting frame 1 and located at the left side of the yarn unwinding discs 2. A dust removal roller 4 and a pre-greasing unit 5 are arranged in sequence on the left side of the mounting frame 1 and located at the left side of the yarn guiding roller 3. The pre-greasing unit 5 is used for pre-greasing and curing treatment of glass fiber yarns. The glass fiber yarn reels are installed in the yarn unwinding discs 2. The glass fiber yarns are guided and conveyed through the yarn guiding roller 3. The surface dust of the glass fiber yarns is removed through the dust removal roller 4 to ensure the cleanliness of the surface of the glass fiber yarns. The dust-removed glass fiber yarns will be conveyed into the pre-greasing unit 5 for pre-greasing and curing treatment. The pre-greased and cured glass fiber yarns will be directly conveyed to the surface of a winding machine for subsequent winding treatment work.

[0020] In some embodiments, a tensioning unit 6 is arranged between the yarn guiding roller 3 and the yarn unwinding disc 2 on the mounting frame 1. The tensioning unit 6 includes two electric push rods 601 installed on the mounting frame 1. A common fixing part of the telescopic parts of the two electric push rods 601 is fixedly connected with an adjusting rod 602. A plurality of threading rings 603 are arranged on the adjusting rod 602. The lifting height of the adjusting rod 602 is controlled through the telescopic parts of the two electric push rods 601, so as to control the self-tension degree of the glass fiber yarns in the threading rings 603. The automatic adjustment is carried out without manual adjustment, and the tension degree of the glass fiber yarns can be adjusted at any time.

[0021] In some embodiments, a plurality of limiting rings 301 are arranged on the yarn guiding roller 3. In this way, the glass fiber yarn is limited and fixed by the limiting rings 301 on the yarn guiding roller 3, preventing the glass fiber yarn from shifting during transportation, causing the glass fiber yarn to twist and affecting the subsequent winding work of the glass fiber yarn on the winding machine.

[0022] In some embodiments, the glass fiber yarn is a glass fiber yarn in a sheet-like structure.

[0023] In some embodiments, a plurality of column feet 101 are provided at the bottom of the mounting frame 1, and a rubber gasket 102 is installed at the bottom of each column foot 101. The mounting frame 1 is supported and fixed by the column feet 101 to ensure the stability of the mounting frame 1 itself. The rubber gasket 102 can increase the friction between the column feet 101 and the ground, further enhancing the stability of the mounting frame 1.

[0024] In some embodiments, the pre-coating unit 5 includes a grease storage tank 501, a guiding roller 502, and a heater 503; the grease storage tank 501 is installed on the mounting frame 1 to the left of the dust removal roller 4. A guiding roller 502 is provided at the top and inside of the grease storage tank 501 respectively, and the heaters 503 are symmetrically arranged on the upper part of the grease storage tank 501.

[0025] The liquid resin is injected into the grease storage tank 501, and the guiding roller 502 inside the grease storage tank 501 is located below the liquid level of the liquid resin, ensuring that the glass fiber yarn can be completely in contact with the liquid resin, guaranteeing the pre-coating effect of the glass fiber yarn. The heaters symmetrically arranged on the upper part of the grease storage tank 501 heat and cure the liquid resin smeared on the surface of the glass fiber yarn, making the glass fiber yarn and the liquid resin on its surface in a cured state, and the glass fiber yarn after the pre-coating and curing is completed is conveyed to the winding surface for winding treatment work through the guiding roller 502 provided at the top of the grease storage tank 501.

[0026] In some embodiments, a grease injection pipe 7 and a grease replacement pipe 8 are provided at the bottom of the grease storage tank 501. Through the grease injection pipe 7 and the grease replacement pipe 8, the liquid resin in the grease storage tank 501 can be replaced in time, ensuring the normal progress of the pre-coating work of the glass fiber yarn.

[0027] In some embodiments, a heat conducting wire 9 and a temperature sensor 10 are installed at the bottom of the grease storage tank 501. The temperature of the liquid resin in the grease storage tank 501 can be controlled through the heat conducting wire 9 to prevent the liquid resin from solidifying. It should be noted that the heat conducting wire 9 only maintains the resin in a liquid state and does not cause it to boil. At the same time, the temperature of the liquid resin can be accurately checked through the temperature sensor 10, facilitating timely adjustment of the working temperature of the heat conducting wire 9.

[0028] Although the embodiments of the present utility model have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present utility model described in the claims. Moreover, the present utility model described herein may have other embodiments and can be implemented or realized in various ways.
