Description

Technical Field

[0001] The present application relates to the field of glass fiber reinforced plastic production equipment, and in particular to a continuous production gluing and stirring device for glass fiber reinforced plastic. Background Art

[0002] Glass fiber reinforced plastic (GFRP), also known as fiber reinforced plastic (FRP), generally refers to a plastic reinforced with glass fiber, an unsaturated polyester, epoxy resin, and phenolic resin matrix, with glass fiber or its products as the reinforcement material. During the FRP production process, a mixed resin material, formed by mixing resin and curing agent, is coated on the fibers, allowing the mixed resin material to blend with the fibers.

[0003] Before applying the mixed resin to the fiber, the resin and curing agent need to be mixed. The existing mixing method involves delivering the resin and curing agent through a delivery pipe into a mixing drum. The delivery pipe's outlet is located above a stirring paddle. The paddle stirs and mixes the resin and curing agent before discharging the mixture through a discharge pipe above the paddle, completing the mixing process. However, some of the resin and curing agent escape the stirring paddle and are discharged through the discharge pipe, resulting in poor mixing of the resin and curing agent. Utility Model Content

[0004] In order to improve the problem that part of the resin and curing agent are not stirred by the stirring paddle during the stirring process, that is, discharged from the discharge pipe, resulting in poor stirring and mixing effect of the stirring device on the resin and curing agent, the present application provides a continuous production glue coating stirring device for fiberglass.

[0005] The present application provides a continuous production glue coating and stirring device for glass fiber reinforced plastics, which adopts the following technical solutions:

[0006] A continuous production glue coating stirring device for glass fiber reinforced plastics comprises a stirring drum mounted on a frame, and a stirring motor mounted on the frame, wherein a stirring shaft inserted into the stirring drum is coaxially fixed to the output shaft of the stirring motor, and a stirring assembly is provided on the portion of the stirring shaft inserted into the stirring drum;

[0007] The resin is delivered to the mixing drum through a first feeding pipe, and the curing agent is delivered to the mixing drum through a second feeding pipe. The outlets of the first feeding pipe and the second feeding pipe are both located below the mixing assembly, and the mixing drum is provided with a discharge pipe above the mixing assembly.

[0008] By adopting the above technical solution, the resin is delivered to the mixing drum through the first feeding pipe, and the curing agent is delivered to the mixing drum through the second feeding pipe. As the curing agent and resin are continuously injected, the stirring motor drives the stirring component through the stirring shaft to stir the curing agent and resin to form a mixed resin material. The mixed resin material flows out from the discharge pipe under the push of the subsequently injected curing agent and resin. Compared with the method of placing the injection material on the stirring component, this solution can fully stir the curing agent and the resin, thereby improving the stirring and mixing effect of the resin and the curing agent.

[0009] In a specific embodiment, the stirring assembly includes a first stirring paddle and a second stirring paddle, and the stirring shaft is connected to the first stirring paddle and the second stirring paddle to drive the first stirring paddle and the second stirring paddle to rotate.

[0010] By adopting the above technical solution, the curing agent and the resin are stirred by the first stirring paddle and the second stirring paddle, thereby improving the mixing effect of the resin and the curing agent.

[0011] In a specific embodiment, the first stirring paddle is fixedly connected to the stirring shaft, the second stirring paddle is rotatably arranged with the stirring shaft, and the stirring shaft and the second stirring paddle are connected via a reversing member to drive the second stirring paddle to rotate in the opposite direction.

[0012] By adopting the above technical solution, when the stirring shaft drives the first stirring paddle to stir the resin and the curing agent, the stirring shaft drives the second stirring paddle to rotate in the opposite direction through the reversing member to stir the resin and the curing agent. The bidirectional rotation of the first stirring paddle and the second stirring paddle can more effectively break the large-scale flow structure in the liquid, promote small-scale mixing, and thus improve the mixing uniformity.

[0013] In a specific possible implementation scheme, the bottom of the stirring shaft passes through the stirring drum, a rotating sleeve is provided on the stirring shaft, the second stirring paddle is fixedly provided on the rotating sleeve, the rotating sleeve extends out of the stirring drum, and one end of the stirring shaft extending out of the stirring drum is connected to the end of the rotating sleeve extending out of the stirring drum through the reversing member so as to drive the rotating sleeve to rotate in the opposite direction.

[0014] By adopting the above technical solution, the reversing member is arranged outside the mixing drum, which can reduce the space occupied by the reversing member in the mixing drum, so that the mixing drum can accommodate more resin and curing agent, thereby improving the mixing efficiency of the resin and curing agent.

[0015] In a specific possible implementation scheme, the reversing member includes a driving gear, a driven gear and an internal gear. The driving gear is coaxially fixed on the stirring shaft, the driven gear is rotatably set on the stirring drum and engages with the outside of the driving gear, and the internal gear is coaxially fixed on the rotating sleeve and engages with the inside of the driven gear.

[0016] By adopting the above technical solution, the stirring shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate in the opposite direction, the driven gear drives the internal gear to rotate in the same direction, and the internal gear drives the second stirring paddle to rotate in the opposite direction to the first stirring paddle through the rotating sleeve, thereby realizing the reverse rotation of the first stirring paddle and the second stirring paddle.

[0017] In a specific embodiment, a protective cover is provided at the bottom of the mixing drum, and the protective cover can cover the reversing member.

[0018] By adopting the above technical solution, the protective cover is used to shield the reversing member, thereby preventing dust, moisture, grease and other pollutants from entering the interior of the reversing member.

[0019] In a specific possible implementation scheme, the driven gear is coaxially fixed with a gear shaft, and the gear shaft is rotatably connected to the protective cover.

[0020] By adopting the above technical solution and utilizing the rotational connection between the gear shaft and the protective cover, the rotational stability of the driven gear is improved.

[0021] In a specific possible implementation scheme, the internal gear and the protective cover are connected via a bearing, and the bearing can support the internal gear in an axial direction.

[0022] By adopting the above technical solution, the arrangement of the bearing can, on the one hand, improve the stability of the circumferential rotation of the rotating sleeve, and on the other hand, improve the stability of the axial position of the rotating sleeve.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Resin is fed into the mixing drum through a first feed pipe, and curing agent is fed into the mixing drum through a second feed pipe. As the curing agent and resin are continuously injected, the stirring motor drives the stirring assembly via the stirring shaft to stir the curing agent and resin to form a mixed resin material. The mixed resin material is then pushed out of the discharge pipe by the subsequent injection of curing agent and resin. Compared with the method of injecting materials on the stirring assembly, this solution can fully stir the curing agent and resin, thereby improving the stirring and mixing effect of the resin and curing agent.

[0025] 2. When the stirring shaft drives the first stirring paddle to stir the resin and the curing agent, the stirring shaft drives the second stirring paddle to rotate in the opposite direction through the reversing member to stir the resin and the curing agent. The bidirectional rotation of the first stirring paddle and the second stirring paddle can more effectively break the large-scale flow structure in the liquid, promote small-scale mixing, and thus improve mixing uniformity.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses a continuous production glue coating and stirring device for glass fiber reinforced plastics.

[0034] Reference Figure 1 、 Figure 2 A continuous production glue coating and stirring device for glass fiber reinforced plastics includes a stirring drum 2 and a stirring motor 3 arranged on a frame 1. In order to meet the needs of continuous production of glass fiber reinforced plastics, the frame 1 in this embodiment is fixedly arranged on a sliding plate on a reciprocating sliding mechanism 4, and a stirring shaft 5 inserted into the stirring drum 2 is coaxially fixed on the output shaft of the stirring motor 3.

[0035] Reference Figure 2 、 Figure 3The stirring shaft 5 is provided with a stirring assembly 6 on the portion inserted into the stirring drum 2, and the stirring drum 2 is provided with a discharge pipe 7 above the stirring assembly 6. The reciprocating sliding mechanism 4 drives the frame 1 to slide back and forth along the width of the fiber, coating the stirred mixed resin material on the fiber. The resin in the resin storage tank is delivered to the stirring drum 2 through the first feed pipe 81, and the curing agent in the curing agent storage tank is delivered to the stirring drum 2 through the second feed pipe 82. Both the first feed pipe 81 and the second feed pipe 82 are rubber hoses, and the outlets of the first feed pipe 81 and the second feed pipe 82 are both located below the stirring assembly 6.

[0036] The resin is delivered to the mixing drum 2 through the first feeding pipe 81, and the curing agent is delivered to the mixing drum 2 through the second feeding pipe 82. As the curing agent and resin are continuously injected, the curing agent and resin rise toward the upper discharge pipe 7. During the rising process, the stirring motor 3 drives the stirring component 6 through the stirring shaft 5 to stir the curing agent and resin to form a mixed resin material. The mixed resin material flows out of the discharge pipe 7 under the push of the subsequent injected curing agent and resin. Compared with the method of injecting material from the top of the stirring component 6, this solution can fully stir the curing agent and resin, thereby improving the stirring and mixing effect of the resin and the curing agent.

[0037] Reference Figure 3 、 Figure 4 The stirring assembly 6 in this embodiment includes a first stirring paddle 61 and a second stirring paddle 62. The first stirring paddle 61 is located above the second stirring paddle 62. The first stirring paddle 61 is fixedly connected to the stirring shaft 5. The bottom of the stirring shaft 5 passes through the bottom of the stirring drum 2 and extends out of the stirring drum 2. A rotating sleeve 21 is rotatably provided on the stirring shaft 5. The rotating sleeve 21 is embedded in the stirring shaft 5. The bottom of the rotating sleeve 21 also passes through the bottom of the stirring drum 2. The rotating sleeve 21 is rotatably sealed with the bottom of the stirring drum 2.

[0038] Reference Figure 3 、 Figure 4 The end of the stirring shaft 5 extending out of the stirring drum 2 is connected to the end of the rotating sleeve 21 extending out of the stirring drum 2 through a reversing member 9. The reversing member 9 is arranged outside the stirring drum 2. The space occupied by the reversing member 9 in the stirring drum 2 can be reduced, so that the stirring drum 2 can accommodate more resin and curing agent, thereby improving the mixing efficiency of the resin and curing agent.

[0039] Reference Figure 4 、 Figure 5A protective cover 22 is fixedly provided at the bottom of the mixing drum 2. A closed space is formed between the protective cover 22 and the mixing drum 2 for the reversing member 9 to be placed. The protective cover 22 shields the reversing member 9 to prevent dust, moisture, grease, and other contaminants from entering the interior of the reversing member 9. The reversing member 9 in this embodiment includes a driving gear 91, a driven gear 92, and an internal gear 93. The driving gear 91 is coaxially fixedly provided on the mixing shaft 5. A gear shaft 94 is coaxially fixedly provided on the driven gear 92. The gear shaft 94 is rotatably connected to the protective cover 22. The driven gear 92 is externally meshed with the driving gear 91. The internal gear 93 is coaxially fixedly provided on the rotating sleeve 21. The driven gear 92 is internally meshed with the internal gear 93. A bearing 95 is provided on the internal gear 93. The bearing 95 in this embodiment is a deep groove ball bearing 95. The inner ring of the bearing 95 is fixedly connected to the internal gear 93, and the outer ring is fixedly connected to the protective cover 22. The bearing 95 can support the axial direction of the internal gear 93, thereby improving the stability of the rotation and axial position of the second stirring paddle 62.

[0040] The stirring shaft 5 drives the driving gear 91 to rotate, the driving gear 91 drives the driven gear 92 to rotate in the opposite direction, and the driven gear 92 drives the internal gear 93 to rotate in the same direction. The internal gear 93 drives the second stirring paddle 62 and the first stirring paddle 61 to rotate in the opposite direction through the rotating sleeve 21, thereby realizing the reverse rotation of the first stirring paddle 61 and the second stirring paddle 62. The bidirectional rotation of the first stirring paddle 61 and the second stirring paddle 62 can more effectively break the large-scale flow structure in the liquid, promote small-scale mixing, and thus improve the mixing uniformity.

[0041] The implementation principle of the glass fiber reinforced plastic continuous production glue coating stirring device of the embodiment of the present application is as follows: the resin is transported to the mixing drum 2 through the first feeding pipe 81, and the curing agent is transported to the mixing drum 2 through the second feeding pipe 82. As the curing agent and resin are continuously injected, the curing agent and resin rise toward the upper discharge pipe 7. During the rising process, the stirring motor 3 drives the stirring shaft 5 to rotate, the stirring shaft 5 drives the driving gear 91 to rotate, the driving gear 91 drives the driven gear 92 to rotate in the opposite direction, and the driven gear 92 drives the internal gear 93 to rotate in the same direction. The internal gear 93 drives the second stirring paddle 62 and the first stirring paddle 61 to rotate in the opposite direction through the rotating sleeve 21, stirring and mixing the curing agent and the resin into a mixed resin material. The mixed resin material flows out of the discharge pipe 7 under the push of the subsequently injected curing agent and resin. This scheme can fully stir the curing agent and the resin, thereby improving the stirring and mixing effect of the resin and the curing agent.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
