Description

Technical Field

[0001] The utility model relates to the technical field of pultruded profiles, in particular to a glue injection anti-overflow device. Background Art

[0002] The composite pultrusion process is a process for producing composite material profiles by impregnating continuous fibers or their fabrics with resin under the traction of a traction device and then heating the forming mold to solidify the resin.

[0003] The composite material pultrusion system must use a dedicated glue injection box. Glue is injected into the box through the glue injection port to soak the fiber layer of the preform, and then heat and cure to achieve molding. During this process, to ensure that the fiber layer is fully in contact with the glue, the operator will continue to inject glue into the glue injection box until the glue is exposed through the feed port between the fiber layer and the glue injection box. In other words, the amount of glue injected is determined by the amount of glue overflow. This method will result in waste of raw materials and increase production costs. It is also difficult to control the glue injection amount and ensure the glue injection effect. In addition, the operator needs to clean the exposed glue, which reduces production efficiency.

[0030] like Figure 1-Figure 3 As shown, this embodiment provides a glue injection overflow prevention device, which includes an overflow box 1, a lower sensor 2 and an upper sensor 3. An overflow chamber 11 is provided inside the overflow box 1. Of the two opposite ends of the overflow chamber 11, one end is connected to the discharge end of the glue injection box 100, and the other end is configured to be penetrated by a fiber member, which can pass through the overflow chamber 11 and enter the glue injection box 100. The receiving end of the lower sensor 2 is arranged in the overflow chamber 11. The lower sensor 2 is electrically connected to the glue injection machine and can control the glue injection machine to inject glue into the glue injection box 100. The receiving end of the upper sensor 3 is arranged in the overflow chamber 11 and is spaced apart from the receiving end of the lower sensor 2 from top to bottom. The upper sensor 3 is electrically connected to the glue injection machine and can control the glue injection machine to stop injecting glue into the glue injection box 100.

[0031] In this embodiment, an overflow chamber 11 is provided within the overflow box 1. Of the two opposing ends of the overflow chamber 11, one end is connected to the discharge end of the glue injection box 100, and the other end is used to pass through the fiber piece. This allows the glue injected into the glue injection box 100 to enter the overflow chamber 11, allowing the fiber piece to pass through the overflow chamber 11, fully contact the glue, and enter the glue injection box 100 for further infiltration. The receiving end of the lower sensor 2 is disposed within the overflow chamber 11. When the glue level within the overflow chamber 11 does not reach a first threshold and cannot fully infiltrate the fiber piece, the lower sensor 2 is electrically connected to the glue injection machine, which can control the glue injection machine to inject glue into the glue injection box 100 to meet the glue injection operation conditions for the fiber piece. The receiving end of the upper sensor 3 is disposed within the overflow chamber 11 and is spaced from the receiving end of the lower sensor 2 from top to bottom, with a fixed height difference, to ensure that the glue level within the fixed height difference can fully infiltrate the fiber piece. When the level of the colloid in the overflow chamber 11 reaches a second threshold, the upper sensor 3 is electrically connected to the glue injection machine, which can control the glue injection machine to stop injecting glue into the glue injection box 100, thereby preventing the colloid from overflowing from the overflow box 1 and causing colloid waste, thereby improving production efficiency. Through the above configuration, the glue injection overflow prevention device of this embodiment can reduce raw material waste, lower production costs, ensure glue injection effect, and improve production efficiency.

[0032] It should be noted that the fiber member can be made of glass fiber or polyester fiber, and this is not limited here. Furthermore, the glue injection box 100 and the glue injection machine are conventional equipment in the field, and the specific principles thereof are well known to those skilled in the art, so they will not be described in detail here. Furthermore, the first and second thresholds described above can be adjusted according to the actual glue injection operation and will not be further explained here.

[0033] Specifically, if Figure 1 and Figure 2 As shown, the overflow box 1 includes a box body 12 and a penetration plate 13. The box body 12 is connected to the glue injection box 100 and is provided with a penetration groove 121 extending along a first direction. The penetration groove 121 is connected to the discharge end of the glue injection box 100. The glue injection box 100 is provided with a through opening on the side, which is the discharge end of the glue injection box 100, to ensure that the glue can flow smoothly from the glue injection box 100 through the penetration groove 121 into the overflow box 1, so that the lower sensor 2 and the upper sensor 3 can control the injection amount in real time. The penetration plate 13 is provided at the end of the box body 12 away from the glue injection box 100, and is surrounded by the penetration groove 121 to form an overflow chamber 11 to prevent the glue from flowing out of the penetration groove 121 away from the end of the glue injection box 100. By providing the penetration plate 13, it is possible to ensure that the glue is contained in the overflow chamber 11 and facilitate the penetration of the fiber parts.

[0034] It should be noted that in this embodiment, the first direction is the direction in which the fiber member moves during the pultrusion process. In other embodiments, the first direction can be adjusted according to the actual pultrusion process and is not limited here.

[0035] More specifically, if Figure 1 and Figure 2 As shown, along the first direction, one end of the box body 12 is detachably connected to the glue injection box 100, and the other end is detachably connected to the penetration plate 13, making the installation, removal, and replacement of the overflow box 1 simple and quick, and convenient for disassembly and cleaning. The detachable connection between the above components can be achieved by screw connection or clamping, etc., which is not limited here.

[0036] More specifically, if Figure 1 and Figure 2 As shown, a plurality of penetration holes 131 are provided on the penetration plate 13, and the plurality of penetration holes 131 are arranged in a matrix at intervals. The penetration holes 131 are configured to penetrate fiber pieces, ensuring that the fiber pieces can be evenly distributed during the penetration process. At the same time, it is also convenient for operators to penetrate the fiber pieces into the corresponding penetration holes 131 according to the specific specifications of the profile, thereby improving work efficiency.

[0037] Specifically, an elastic member is positioned within the threading hole 131. This elastic member abuts against the fiber member, exerting a certain pressure to stabilize the fiber member during threading and prevent it from shaking or shifting. Furthermore, the provision of the elastic member reduces the gap between the threading hole 131 and the fiber member, further enhancing the anti-overflow effect of the colloid and preventing it from escaping through the gap. The elastic member can be made of nitrile rubber or chloroprene rubber, without further limitation.

[0038] Specifically, if Figure 1 and Figure 2 As shown, the box body 12 includes an upper cover 122 and a lower tank 123. The upper cover 122 is detachably connected to the lower tank 123, forming a through-hole 121, which facilitates assembly and disassembly by the operator without the need for complex tools or procedures. After the box body 12 is disassembled, the interior of the box body 12 can be easily cleaned and maintained, ensuring the long-term and stable use of each component. The detachable connection between the above components can be achieved by bolts or snap fasteners, which are not further limited here.

[0039] Specifically, if Figure 1-Figure 3 As shown, one of the upper cover body 122 and the lower trough body 123 is provided with a connecting protrusion 1221, and the other is provided with a connecting recess 1231. The upper cover body 122 and the lower trough body 123 can be connected to each other by snapping the connecting protrusion 1221 into the connecting recess 1231. The operator only needs to align the connecting protrusion 1221 with the connecting recess 1231 and apply appropriate force to achieve the connection or disassembly of the upper cover body 122 and the lower trough body 123, thereby improving the convenience and efficiency of operation.

[0040] More specifically, if Figure 3As shown, in this embodiment, there are two connecting protrusions 1221, and the two connecting protrusions 1221 are respectively spaced apart on one end of the upper cover body 122 facing the lower trough body 123, and there are two connecting recesses 1231, and the two connecting recesses 1231 are respectively spaced apart on one end of the lower trough body 123 facing the upper cover body 122. Such a setting can ensure that two connection points are formed between the upper cover body 122 and the lower trough body 123, ensuring that the box body 12 is more stable when connected, reducing the risk of separation of the box body 12 due to loosening of a single connection point, and helping to maintain the balance and stability of the box body 12 when connected.

[0041] More specifically, in other embodiments, the connecting protrusion 1221 can also be set on the lower trough body 123, and the connecting recess 1231 can be set on the upper cover body 122. The lower trough body 123 and the upper cover body 122 are connected by cooperating with each other through the connecting protrusion 1221 and the connecting recess 1231, and no further restrictions are made here.

[0042] Specifically, an overflow hole is provided on the overflow box 1, and the overflow chamber 11 is connected to the outside through the overflow hole. The position of the overflow hole is higher than the receiving end of the upper sensor 3. When the liquid accumulates to a certain height in the overflow chamber 11 and the upper sensor 3 fails, or when the colloid in the overflow chamber 11 reaches the second threshold, but the colloid still flows out after the injection machine stops injecting due to a response delay, in order to ensure the normal injection effect, the colloid will be naturally discharged through the overflow hole to ensure the quality of the operation.

[0043] Specifically, if Figure 1 and Figure 2As shown, in this embodiment, the lower sensor 2 and the upper sensor 3 are both liquid level sensors. The receiving end of the lower sensor 2 is disposed in the overflow chamber 11. When the colloid height in the overflow chamber 11 does not reach the first threshold value (i.e., the minimum liquid level at which the colloid cannot fully soak the fiber parts), and the fiber parts cannot be fully soaked, the lower sensor 2 will transmit a signal to the alarm to notify the operator to pay attention to the glue injection operation. The lower sensor 2 is electrically connected to the glue injection machine, which then controls the glue injection machine to inject glue into the glue injection box 100 to meet the glue injection operation conditions of the fiber parts and ensure that the fiber parts always have sufficient glue for soaking during the glue injection process. The receiving end of the upper sensor 3 is disposed in the overflow chamber 11 and is spaced from the receiving end of the lower sensor 2 from top to bottom, with a fixed height difference, to ensure that the colloid height is within the fixed height difference and can fully soak the fiber parts. When the level of the colloid in the overflow chamber 11 reaches a second threshold (i.e., the highest level that causes colloid overflow), the upper sensor 3 is electrically connected to the glue injection machine, which can control the glue injection machine to stop injecting glue into the glue injection box 100, thereby preventing the glue from overflowing from the overflow box 1 and causing waste, saving production costs and improving production efficiency. By providing dual liquid level sensors, the amount of glue injected into the glue injection box 100 can be accurately controlled, ensuring that the fiber parts are fully soaked while preventing colloid overflow. Moreover, by automatically controlling the glue injection and stopping operations of the glue injection machine, the need for manual intervention is reduced, thereby improving production efficiency.

[0044] More specifically, in other embodiments, the lower sensor 2 and the upper sensor 3 may also adopt capacitive sensors, pressure sensors, etc., that is, the specific structures of the lower sensor 2 and the upper sensor 3 are not limited, as long as they can achieve the above functions.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
