[0003] In the traditional winding molding process, the resin content cannot be accurately controlled, resulting in uncertainty in the actual production thickness of the pipe products. This will lead to three adverse consequences: First, the resin content of the pipe products is unstable, and the wall thickness fluctuates greatly, resulting in inaccurate control of the outer diameter of the pipe products and inability to guarantee the stability of product quality; Second, too large resin content will lead to an increase in resin loss and waste of cost; Third, too large resin content will lead to too thick thickness of the pipe products, and then due to agglomeration heat release, explosive polymerization will occur, resulting in delamination and cracking of the pipe products, which will not only cause economic losses but also pose potential safety hazards for the safe operation of the pipe products. Therefore, it is necessary to control the resin content in the winding molding process.

[0038] Figure 1 Schematic diagram showing the winding and glue scraping device provided by the embodiment of the present utility model; Figure 2 Schematic diagram showing the internal structure of the winding and glue scraping device provided by the embodiment of the present utility model. Referring to Figure 1 and Figure 2 , this embodiment provides a winding and glue scraping device for quantitatively controlling the glue content during the winding forming process of the winding yarn 10.

[0039] Specifically, the winding and sizing device includes a glue tank 100, a winding die 200, and a loading mechanism 300. The glue tank 100 contains glue liquid. The winding yarn 10 extends into the glue tank 100 from the extending-in side, adheres to the glue liquid, and then extends out from the extending-out side of the glue tank 100 and winds around the winding die 200. The extending-in side and the extending-out side are oppositely arranged. After passing through the glue tank 100, the winding yarn 10 can adhere to the glue liquid. In this embodiment, the glue liquid is specifically resin glue liquid.

[0040] More specifically, the loading mechanism 300 includes a bearing part 310, a glue pressing part 320, and a plurality of gravity blocks 330. The bearing part 310 is inclined between the glue tank 100 and the winding die 200. The setting height of the winding die 200 is lower than the top end of the glue tank 100. One end of the bearing part 310 is arranged at the top end of the glue tank 100 and extends towards the winding die 200. The glue pressing part 320 is arranged at the end of the bearing part 310 away from the glue tank 100 and can press against the winding yarn 10 on the side of the winding die 200 to scrape off the excess glue liquid on the winding yarn 10, thereby preventing the problem of excessive glue content in the formed pipeline product.

[0041] Even more specifically, the gravity blocks 330 are detachably arranged on the bearing part 310, and the pressure of the glue pressing part 320 on the winding die 200 can be adjusted by the number of the gravity blocks 330. The bearing part 310 may include two rod-shaped structures arranged in parallel and at intervals. Two ends of the glue pressing part 320 are respectively connected to the two rod-shaped structures. Two through holes are spaced apart on the gravity block 330, and the two through holes are respectively used for passing through the two rod-shaped structures. Through the above settings, the detachable connection between the gravity block 330 and the bearing part 310 can be realized by the way of passing through.

[0042] Since the above-mentioned bearing part 310 is inclined, the gravity blocks 330 assembled on it will press on the glue pressing part 320 under the action of gravity to increase the pressure of the glue pressing part 320 on the winding die 200. The weight of the gravity block 330 is known. Then, for each additional gravity block 330, the pressure of the glue pressing part 320 on the winding die 200 can be increased quantitatively. The weights of the plurality of gravity blocks 330 can be the same or different. In this embodiment, the weight of each gravity block 330 is the same. Through the above settings, the pressure of the glue pressing part 320 on the winding die 200 can be changed quantitatively to realize the quantitative control of the glue content of the winding yarn 10 during the winding process, and improve the uniformity of the wall thickness of the pipeline product and the stability of the winding quality.

[0043] Continue to refer to Figure 1 - Figure 2 , the winding and sizing device further includes a storage rack 700. The storage rack 700 is arranged at intervals on the extending-in side of the glue tank 100, and the storage rack 700 can accommodate the yarn roll of the winding yarn 10.

[0044] Specifically, the storage rack 700 includes multiple layers of storage plates 710. The multiple storage plates 710 are parallel to each other and are spaced apart in the vertical direction. Each storage plate 710 accommodates multiple yarn rolls. The types of each yarn roll can be different or the same, and need to be selected and determined according to the actual characteristic requirements of the pipeline product. The types are not elaborated in this embodiment.

[0045] More specifically, a plurality of yarn passing holes 120 are formed on the extending side of the glue box 100. The multiple yarn passing holes 120 are arranged in a rectangular array, and multiple strands of the winding yarn 10 can respectively pass through the multiple yarn passing holes 120 and extend into the glue box 100. The yarn passing holes 120 can guide the winding yarn 10 to smoothly extend into the glue box 100.

[0046] Even more specifically, a glue groove 110 is provided on the inner side of the bottom of the glue box 100, and the glue liquid is accommodated in the glue groove 110. In this embodiment, there are multiple glue grooves 110, and the glue liquid is accommodated in each of the multiple glue grooves 110 to improve the uniformity of the distribution of the glue liquid at the bottom of the glue box 100.

[0047] Continue to refer to Figure 1 and Figure 2 , the glue pressing member 320 is a roller-shaped structure or a plate-shaped structure arranged along the length direction of the winding mold 200. In this embodiment, the glue pressing member 320 is a roller-shaped structure that can rotate around its own axis, so as to improve the smoothness of the winding yarn 10 passing between the winding mold 200 and the glue pressing member 320 while ensuring the pressing effect on the winding mold 200.

[0048] Specifically, the winding and glue scraping device further includes a guide rail 600. The guide rail 600 is arranged parallel to the axis direction of the winding mold 200. A roller 130 is provided at the position of the bottom of the glue box 100 corresponding to the guide rail 600. The glue box 100 can move along the guide rail 600 driven by the roller 130, and thus wind the winding yarn 10 along the length direction of the winding mold 200.

[0049] More specifically, the winding and glue scraping device further includes a yarn pressing member 400. The yarn pressing member 400 is arranged inside the glue box 100. The winding yarn 10 extending into the extending side bypasses the yarn pressing member 400 and then extends out of the extending side. The yarn pressing member 400 can press the winding yarn 10 below the liquid level of the glue liquid. Through the above settings, it can be ensured that the winding yarn 10 fully contacts the glue liquid during the process of passing through the glue box 100.

[0050] More specifically, in this embodiment, the yarn pressing member 400 is of a roller structure and is rotatably arranged in the glue tank 100 around its own axis. The rotation axis of the yarn pressing member 400 is parallel to the axis direction of the winding die 200. Through the above arrangement, on the premise of ensuring that the winding yarn 10 is pressed into the glue, the smoothness of the winding yarn 10 passing through the glue tank 100 can be improved.

[0051] More specifically, the winding and scraping glue device further includes a yarn dividing comb 500. The yarn dividing comb 500 is arranged on the extending side, and multiple strands of the winding yarn 10 can be combed by the yarn dividing comb 500 and extend out of the extending side in a side-by-side manner. Through the above arrangement, the winding yarn 10 to be wound onto the winding die 200 can be regularized, and the winding effect can be improved.

[0052] The using process of the winding and scraping glue device provided in this embodiment is as follows:

[0053] First, the winding yarn 10 of the yarn roll on the accommodating rack 700 passes through the threading hole 120, then passes under the yarn pressing member 400, and is then wound onto the winding die 200 after being arranged neatly by the yarn dividing comb 500;

[0054] Then, an appropriate amount of glue is added to the glue tank 110, and the added amount of the glue is subject to meeting the winding requirements;

[0055] Finally, according to the dripping situation of the glue on the winding die 200 after being scraped by the glue pressing member 320, an appropriate number of gravity blocks 330 are assembled on the bearing portion 310. The specific number of the gravity blocks 330 needs to be increased or decreased according to the dripping situation of the glue during the production process and will not be changed once determined. If the dripping of the glue is excessive, the number of the gravity blocks 330 is reduced; if the dripping of the glue is too little, the number of the gravity blocks 330 is increased.

[0056] It should be noted that for winding dies 200 with different diameters, different seasons, and different temperatures and humidities, the required number of the gravity blocks 330 may also be different, and the specific number is determined according to the actual situation.

[0057] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model.
