Description

Technical Field

[0001] The utility model relates to the technical field of pultruded profiles, in particular to a material removing device. Background Art

[0002] As Figure 1 and Figure 2 shown, the production of glass fiber profiles requires impregnating glass fibers with resin and then completing it through an extrusion forming device. Before the impregnated glass fibers enter the extrusion forming device, it is necessary to remove the excess resin on the glass fibers to prevent the resin from affecting the production of glass fiber profiles. However, if too much resin is removed, defects will occur in the glass fiber profiles. If too little resin is removed, the resin will be extruded when entering the feed port of the extrusion forming device, resulting in a large amount of resin accumulating at the feed port. Moreover, the one-time extrusion of a large amount of resin concentrated at the feed port will affect the production efficiency of the profiles and may even cause deformation of the glass fibers inside the profiles, affecting the quality of the pultruded profiles. Content of the Utility Model

[0003] The purpose of the utility model is to provide a material removing device, which can uniformly remove the resin on the glass fibers and improve the production efficiency and product quality of the pultruded profiles.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A material removing device, comprising:

[0006] A material removing member, with a material receiving cavity inside. The material receiving cavity extends along a first direction. At both ends of the material removing member along the first direction, there are respectively a feed port and a discharge port. The material receiving cavity is communicated with the outside through the feed port and the discharge port. From the feed port to the discharge port, the inner diameter of the material receiving cavity gradually decreases along the first direction. The material removing member is also provided with a plurality of discharge channels. The plurality of discharge channels are arranged at intervals along the circumferential direction of the material receiving cavity. One end of the discharge channel is communicated with the material receiving cavity, and the other end is configured to discharge the resin.

[0007] Optionally, the material removing device further comprises an impregnation chamber, and the other end of the discharge channel is communicated with the inside of the impregnation chamber.

[0008] Optionally, the extending direction of the discharge channel is arranged at an angle with the first direction.

[0009] Optionally, the extending directions of the plurality of discharge channels are arranged parallel to each other.

[0016] Advantages of the present utility model:

[0017] The present utility model provides a material removing device, which includes a material removing member. A material receiving cavity is provided inside the material removing member. The material receiving cavity extends along a first direction. The two ends of the material removing member along the first direction are respectively provided with a feeding port and a discharging port. The material receiving cavity communicates with the outside through the feeding port and the discharging port, so that the impregnated glass fiber can enter the material receiving cavity through the feeding port and then be discharged to the outside through the discharging port. From the feeding port to the discharging port, the inner diameter of the material receiving cavity gradually decreases along the first direction, so that the glass fiber will be extruded by the inner wall of the material receiving cavity when passing through the material receiving cavity, thereby removing the resin on the glass fiber more evenly, reducing the defects of the glass fiber profile caused by excessive resin removal. The material removing member is further provided with a plurality of discharging channels. The plurality of discharging channels are arranged at intervals along the circumferential direction of the material receiving cavity. One end of the discharging channel communicates with the material receiving cavity, and the other end is configured to discharge the resin. Such a setting can more effectively discharge the redundant resin on the glass fiber. When the glass fiber passes through the material receiving cavity, the redundant resin can be discharged through the plurality of discharging channels, improving the production efficiency and the profile quality, and avoiding the accumulation of resin at the feeding port of the extrusion molding device. Through the above setting, the material removing device of the present application can evenly remove the resin on the glass fiber, improving the production efficiency and the product quality of the pultruded profile.

[0027] Such as Figure 3As shown in the figure, this embodiment provides a material removing device, which includes a material removing member 1. A material receiving cavity 11 is provided inside the material removing member 1. The material receiving cavity 11 extends along a first direction. At both ends of the material removing member 1 along the first direction, a feed inlet 12 and a discharge outlet 13 are respectively provided. The material receiving cavity 11 communicates with the outside through the feed inlet 12 and the discharge outlet 13. From the feed inlet 12 to the discharge outlet 13, the inner diameter of the material receiving cavity 11 gradually decreases along the first direction. A plurality of discharge channels 14 are also provided on the material removing member 1. The plurality of discharge channels 14 are arranged at intervals along the circumferential direction of the material receiving cavity 11. One end of the discharge channel 14 communicates with the material receiving cavity 11, and the other end is configured to discharge resin.

[0028] In this embodiment, a material receiving cavity 11 is provided inside the material removing member 1. The material receiving cavity 11 extends along a first direction. At both ends of the material removing member 1 along the first direction, a feed inlet 12 and a discharge outlet 13 are respectively provided. The material receiving cavity 11 communicates with the outside through the feed inlet 12 and the discharge outlet 13, so that the impregnated glass fiber can enter the material receiving cavity 11 through the feed inlet 12 and then be discharged to the outside through the discharge outlet 13. From the feed inlet 12 to the discharge outlet 13, the inner diameter of the material receiving cavity 11 gradually decreases along the first direction, so that the glass fiber will be squeezed by the inner wall of the material receiving cavity 11 when passing through the material receiving cavity 11, thereby more evenly removing the resin on the glass fiber and reducing the defects of the glass fiber profile caused by excessive resin removal. A plurality of discharge channels 14 are also provided on the material removing member 1. The plurality of discharge channels 14 are arranged at intervals along the circumferential direction of the material receiving cavity 11. One end of the discharge channel 14 communicates with the material receiving cavity 11, and the other end is configured to discharge resin. Such a setting can more effectively discharge the excess resin on the glass fiber. When the glass fiber passes through the material receiving cavity 11, the excess resin can be discharged through the plurality of discharge channels 14, improving the production efficiency and the quality of the profile, and avoiding the accumulation of resin at the feed inlet 12 of the extrusion forming device. Through the above setting, the material removing device of this embodiment can evenly remove the resin on the glass fiber, improving the production efficiency and product quality of the pultruded profile.

[0029] The specific structure of the material removing device will be described below:

[0030] Specifically, as Figure 3 shown, in this embodiment, the material removing member 1 is a tubular structure to facilitate the conveying of the pultruded profile and the removal of excess resin. In other embodiments, the material removing member 1 is a block structure, that is, as long as the above functions can be achieved, the specific structure of the material removing member 1 is not limited too much here.

[0031] Specifically, as Figure 3As shown, the removal device also includes an impregnation tank 2. The other end of the discharge channel 14 is connected to the interior of the impregnation tank 2. Excess resin removed from the glass fiber can be discharged into the impregnation tank 2 through the discharge channel 14, rather than directly discharged into the external environment. This helps to reuse the resin and reduce resource waste. In addition, the impregnation tank 2 can serve as a container for collecting and storing excess resin, providing spare resin for subsequent pultrusion profile production.

[0032] Specifically, if Figure 3 As shown, the extending direction of the discharge channel 14 is set at an angle with the first direction, which can more effectively strip the resin from the glass fiber and transport the resin to the impregnation chamber 2 through the discharge channel 14. It can be understood that the impregnated glass fiber can enter the receiving cavity 11 through the feed port 12 along the first direction and then be discharged through the discharge port 13. The discharge direction of the stripped resin in the discharge channel 14 is set at an acute angle with the transport direction of the glass fiber to facilitate the discharge of the resin.

[0033] More specifically, if Figure 3 As shown, the extension directions of the multiple discharge channels 14 are arranged parallel to each other and can be more evenly distributed around the receiving cavity 11, so that the resin can be stripped and discharged from multiple positions of the glass fiber at the same time, avoiding excessive accumulation of resin at a certain local position.

[0034] Specifically, if Figure 3 As shown, the discharge channel 14 is connected to the receiving chamber 11 at one end and is provided with a discharge port 141. The multiple discharge ports 141 are arranged at intervals along the first direction, which can ensure that when the glass fiber passes through the receiving chamber 11, the resin on the glass fiber can be removed simultaneously through the multiple discharge ports 141, and the resin removal is more uniform.

[0035] More specifically, the diameter of the discharge port 141 is 0.1-1 cm to ensure good removal of the resin.

[0036] Specifically, if Figure 3 As shown, the material removal component 1 is also provided with an extrusion channel 15, and the material receiving chamber 11 is connected to the material outlet 13 through the extrusion channel 15, so that before the glass fiber enters the material outlet 13 from the material receiving chamber 11, it will undergo additional extrusion operation of the extrusion channel 15 to further remove the residual resin on the glass fiber, ensuring that the resin layer on the surface of the glass fiber is more uniform, thereby improving the quality and appearance of the product.

[0037] More specifically, if Figure 3As shown, in this embodiment, the extrusion channel 15 extends along the first direction and has a cylindrical structure, which can ensure that the glass fiber is subjected to a uniform extrusion force when passing through the extrusion channel 15, thus helping to remove the residual resin on the glass fiber more evenly and avoiding the situation of excessive or insufficient local resin. In other embodiments, the extrusion channel 15 has a cuboid structure, that is, the specific structure of the extrusion channel 15 is not limited as long as the above functions can be achieved.

[0038] Specifically, as Figure 3 shown, the diameter of the feed inlet 12 is larger than the diameter of the discharge outlet 13, so that the glass fiber can be more easily and smoothly conveyed into the receiving cavity 11.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. 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 invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
