[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the utility model.

[0044] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] In the production process of pultruded side panels, the yarn first enters the resin tank for resin infiltration, so that the resin is fully infiltrated and dispersed on the surface and inside of the yarn. Then the yarn with resin is combined with the felt and enters the molding mold.

[0046] In the prior art, the yarn bundles are directly combined with the felt after passing through the dipping tank. During the dipping process, the yarn bundles will not be well soaked after the entire yarn bundles enter the dipping tank, which will cause the felt to be misaligned and the yarn and felt to separate. In addition, the resin may be used too much and the excess resin may spill out of the dipping tank, thereby increasing the production cost.

[0047] Combine the following Figure 1-Figure 5 The embodiments of the present utility model are further described.

[0048] In order to solve the above technical problems, the utility model provides a pultrusion side plate dipping device. By arranging yarn guide components at the entrance and exit of the dipping tank, it is convenient to arrange the distribution of yarns reasonably. The yarns enter the dipping tank after passing through the yarn guide components at the entrance. A pressure roller component is arranged inside the dipping tank. After entering the dipping tank, the yarns are completely immersed in resin through the pressure roller component to ensure that the yarns are fully soaked in resin, thereby improving the uniformity and quality of dipping, and avoiding the separation of yarns and felts. Then, by arranging a yarn guide component at the exit of the dipping tank, the excess resin on the yarns is scraped off, and the excess resin is returned to the dipping tank, thereby improving the utilization rate of the resin, realizing the recycling of the resin, and reducing the production cost. The yarns impregnated with resin are accurately positioned by the first positioning structure of the positioning device, and the felt output by the felt hanging part is positioned by the second positioning structure. This double positioning ensures the accurate alignment of the yarns and the felts during the compounding process, and prevents the yarns and the felts from being offset, thereby improving the accuracy and quality of the compounding.

[0049] An exemplary embodiment of the present disclosure provides a pultruded side plate dipping device, referring to Figure 1 , comprising a first frame 1, a second frame 2 and a positioning device 6. For example, referring to Figure 1 The second frame 2 includes two first support columns 21 arranged in parallel, and the second support column 22 is connected to the upper ends of the two first support columns 21, wherein the two first support columns 21 are respectively arranged on both sides of the first frame 1, and the second support column 22 is arranged above the first frame 1, that is, the first frame 1 is arranged through the second frame 2.

After entering the dipping tank 3, the yarn is completely immersed in the resin through the pressing roller assembly 4, ensuring that the yarn is fully soaked in the resin, thereby improving the uniformity and quality of the dipping, and avoiding the separation of the yarn and the felt. Then, by providing the yarn guide assembly 5 at the exit of the dipping tank 3, the excess resin on the yarn is scraped off, so that the excess resin flows back into the dipping tank 3, the utilization rate of the resin is improved, the recycling of the resin is realized, and the production cost is reduced.

The felt is positioned by the felt slots 63 and then compounded with the yarn.

[0055] Exemplarily, the first felt hanging group 7 includes three first felt hanging disks 71, the first support column 21 is a rectangular structure, and the three first felt hanging disks 71 are respectively arranged on the three side surfaces of one of the first support columns 21 close to the dipping tank 3, wherein the setting height of the first felt hanging disk 71 close to the positioning plate 61 is higher than the setting heights of the other two first felt hanging disks 71, and a first fixing rod 72 is provided at the center position of each first felt hanging disk 71. The unused felt will form a felt roll with a hollow center, and the felt roll is mounted on the first fixing rod 72. When the felt is in use, the felt roll can rotate on the first felt hanging disk 71 with the first fixing rod 72 as the rotating axis. By setting the first felt hanging disc 71 at different heights, the felt can be transported along a predetermined path. The first felt hanging disc 71 on the side close to the positioning plate 61 is higher, which can ensure that the felt passes smoothly through the felt threading slot 63 above the threading hole 62, while the felt output by the other first felt hanging discs 71 far away from the positioning plate 61 passes through the felt threading slot 63 below the threading hole 62, or passes through the felt threading slot 63 on the side close to the first felt hanging group 7, that is, Figure 1 The felt threading slot 63 on the left side of the middle threading hole 62 makes the transmission more stable when multiple layers of felt are laid simultaneously, and also avoids the crossing or interference between the felts, thereby ensuring the quality of the composite.

[0056] The second felt group 8 includes a plurality of second felt discs 81, which are arranged around the circumference of the second frame 2, and the height of the second felt disc 81 close to the positioning plate 61 is higher than that of other second felt discs 81. Second fixing rods 82 are provided on the plurality of second felt discs 81, and the second fixing rods 82 are used to install and support felt. The felt slots 63 arranged above the yarn threading hole 62 are used for the felt output from the second felt disc 81 close to the positioning plate 61 to pass through, and the felt slots 63 arranged below the yarn threading hole 62 or close to the second felt group 8 are used for the felt output from other second felt discs 81 away from the positioning plate 61. The felt is positioned by the felt slots 63 and then compounded with the yarn.

[0057] Exemplarily, the second felt hanging group 8 includes three second felt hanging plates 81, the first support column 21 is a rectangular structure, and the three second felt hanging plates 81 are respectively arranged on the three side surfaces of another first support column 21 close to the dipping tank 3, wherein the setting height of the second felt hanging plate 81 close to the positioning plate 61 is higher than the setting heights of the other two second felt hanging plates 81, and a second fixing rod 82 is provided at the center position of each second felt hanging plate 81, and the felt roll is sleeved on the second fixing rod 82. When the felt is in use, the felt roll can rotate on the second felt hanging plate 81 with the second fixing rod 82 as the rotating axis. By setting the second felt hanging disc 81 at different heights, the felt can be transported along a predetermined path. The second felt hanging disc 81 on the side close to the positioning plate 61 is higher, which can ensure that the felt passes smoothly through the felt threading slot 63 above the yarn threading hole 62, while the felt output from the other second felt hanging discs 81 far away from the positioning plate 61 passes through the felt threading slot 63 below the yarn threading hole 62, or passes through the felt threading slot 63 on the side close to the second felt hanging group 8, that is, Figure 1 The felt threading slot 63 on the right side of the middle threading hole 62 makes the transmission more stable when multiple layers of felt are laid simultaneously, and also avoids the crossing or interference between the felts, thus ensuring the quality of the composite.

[0058] In some embodiments of the present invention, referring to Figure 1 The third felt hanging group 9 includes at least one felt hanging rack, which includes a first hanging rod 91 and a second hanging rod 92. The upper end of the first hanging rod 91 is connected to the second frame 2, and the lower end of the first hanging rod 91 extends toward the direction close to the dipping tank 3 and is vertically connected to the second hanging rod 92. The second hanging rod 92 is used to place felt, and the felt threading slot 63 provided above the yarn threading hole 62 is used for the felt output by the second hanging rod 92 to pass through.

Exemplarily, the third felt hanging group 9 includes a felt hanging rack, wherein the upper end of the first hanging rod 91 is connected to the second support column 22, and the lower end of the first hanging rod 91 is vertically connected to the second hanging rod 92, that is, the second hanging rod 92 is arranged parallel to the second support column 22. When in use, the felt roll is sleeved on the second hanging rod 92, and the felt roll can rotate with the second hanging rod 92 as the shaft. When the felt needs to be laid on top of the yarn, the felt on the felt hanging rack is compounded with the yarn to avoid crossing or interference between the felts, reduce problems such as misalignment or wrinkles that may occur during the compounding process, and ensure the quality of the compounding.

[0059] In some embodiments of the present invention, referring to Figure 1 and Figure 4The roller assembly 4 includes two support plates 41, which are respectively supported on the top surfaces of the two opposite groove walls of the dipping tank 3. The roller assembly 4 also includes a first roller 42, a second roller 43, and a connecting rod 44 located at both ends of the first roller 42 and the second roller 43; wherein the length of the first roller 42 is equal to that of the second roller 43, and the difference between the length of the first roller 42 plus the thickness of the two connecting rods 44 and the width of the dipping tank 3 is between 0.5-1 cm. One end of one of the connecting rods 44 is connected to the support plate 41 on its side, and the other end is connected to the first end of the first roller 42 and the first end of the second roller 43; one end of the other connecting rod 44 is connected to the support plate 41 on its side, and the other end is connected to the second end of the first roller 42 and the second end of the second roller 43, wherein the first roller 42 is arranged below the second roller 43, and the gap between the first roller 42 and the second roller 43 is for the yarn to pass through. When the resin content is high, the yarn can be selected to pass through the gap between the first pressing roller 42 and the second pressing roller 43 to ensure that the yarn can fully contact and absorb the resin; when the resin content is low, the yarn can be selected to pass from below the first pressing roller 42 to achieve more precise dipping control. In this way, the two support plates 41 are stably supported on the top surfaces of the two opposite groove side walls 32 of the dipping tank 3, providing a stable foundation for the pressing roller assembly 4, ensuring that the pressing roller can run stably during the dipping process, preventing the dipping effect from being affected by shaking or displacement, ensuring that the yarn is fully soaked in the resin, thereby improving the uniformity and quality of dipping.

[0060] In some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 4 The pressure roller assembly 4 further includes a support rod 45, and both ends of the support rod 45 are respectively connected to the two support plates 41. Figure 4 The support rod 45 is arranged above the first pressing roller 42 and the second pressing roller 43. By arranging the support rod 45, the overall stability of the pressing roller assembly 4 is enhanced, and the shaking or displacement that may occur during the operation of the pressing roller assembly 4 is effectively prevented, thereby ensuring that the yarn can obtain a uniform and stable dipping effect when passing through the first pressing roller 42 or the second pressing roller 43, thereby improving the product quality.

[0061] In some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3, the cross-sectional area of ​​the dipping tank 3 gradually decreases from the end close to the yarn guide assembly 5 to the end away from the yarn guide assembly 5, and a through hole 33 is provided at the end away from the yarn guide assembly 5, and the through hole 33 is used to communicate with the reflux pump. It can be understood that the longitudinal section of the dipping tank 3 is a trapezoidal structure with a long upper side and a short lower side, and a through hole 33 is provided at the bottom center of the dipping tank 3. The trapezoidal structure makes reasonable use of the capacity of the dipping tank 3, while maintaining sufficient dipping space, reducing the waste of resin. The through hole 33 is provided at the bottom of the dipping tank 3 to communicate with the reflux pump to realize the recycling of resin. During the dipping process, excess resin or resin not absorbed by the yarn can be returned to the dipping tank 3 through the reflux pump, thereby improving the utilization rate of the resin and reducing the production cost.

[0062] In some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3 , the dipping tank 3 includes a tank bottom wall 31 and a plurality of tank side walls 32 connected to the tank bottom wall 31, and the projection of the pressure roller assembly 4 on the horizontal plane is located within the projection of the tank bottom wall 31 on the horizontal plane. Exemplarily, the longitudinal section of the dipping tank 3 is a trapezoidal structure, the top of the dipping tank 3 is an opening structure, the length of the opening is longer than the length of the tank bottom wall 31, the four tank side walls 32 are inclined, and the upper ends of the four tank side walls 32 together constitute the opening structure, that is, the pressure roller assembly 4 is arranged in the area where the maximum depth of the dipping tank 3 is located. In this way, the resin in the dipping tank 3 will all converge above the tank bottom wall 31, and the pressure roller assembly 4 is arranged in the maximum depth area of ​​the dipping tank 3. Even in the case of less resin, the yarn can still contact a higher concentration of resin when passing through the dipping tank 3, further ensuring that the yarn is subjected to sufficient pressure and dipping time in the maximum depth area, so that the yarn is fully soaked, thereby reducing unnecessary waste of resin and reducing production costs.

[0063] Exemplarily, a clamping portion 34 is provided on both side walls 32 of the dipping tank 3 near the second frame 2, wherein the clamping portion 34 includes a first fixed plate 341 roller assembly 4 and a second fixed plate 342 support plate 41 arranged at an angle, the first side edge of the first fixed plate 341 roller assembly 4 is connected to the periphery of the opening of the tank side wall 32, and the second side edge of the first fixed plate 341 roller assembly 4, which is away from the first side edge, is connected to the second fixed plate 342 support plate 41. In this embodiment, the first fixed plate 341 roller assembly 4 is vertically arranged with the tank side wall 32, and the second fixed plate 342 support plate 41 is vertically arranged with the first fixed plate 341 roller assembly 4. The lower bottom surface of the first fixed plate 341 roller assembly 4 abuts against the upper end surface of the frame rod in the first frame 1, and the second fixed plate 342 support plate 41 abuts against the outer side surface of the frame rod. In this way, the upper end surfaces of the rack rods are in contact, providing vertical support for the over-dipping tank 3, ensuring that it can maintain a stable position during use. The second fixing plate 342 and the support plate 41 are in contact with the outer side surface of the rack rod, further enhancing the horizontal stability of the dipping tank 3, preventing it from shaking or tilting, and ensuring that the over-dipping tank 3 can be firmly fixed to the first rack 1 through the clamping portion 34, and is not easy to fall off or shift.

[0064] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The yarn guide assembly 5 includes a yarn guide plate 51, and a plurality of yarn guide holes 52 are provided on the yarn guide plate 51, and the plurality of yarn guide holes 52 are evenly distributed on the yarn guide plate 51. In this way, the even distribution of the yarn guide holes 52 can ensure that the yarn is more evenly distributed when entering the dipping tank 3, reduce the crossing and interference between the yarns, ensure that each yarn can be soaked in resin, and thus avoid the problem of separation of the yarn and the felt due to poor yarn soaking.
