Description

Technical Field

[0001] The utility model belongs to the technical field of pultrusion equipment, and in particular relates to a glue dipping device for composite material pultrusion equipment. Background Art

[0002] The pultrusion process is a method for continuously producing composite material profiles. It is an automated production process in which the untwisted glass fiber roving and other continuous reinforcement materials, polyester surface felt, etc. on the creel are impregnated with resin, and then passed through a forming mold that maintains a certain cross-sectional shape. After curing and forming in the mold, the pultruded products are continuously ejected from the mold, thereby forming pultruded products.

[0003] The products produced by pultrusion process have higher tensile strength than ordinary steel, and the resin-rich layer on the surface gives them good corrosion resistance. Therefore, they are the best products to replace steel in projects with corrosive environments. They are widely used in transportation, electrical engineering, electrical insulation, chemical industry, mining, ocean, boats, corrosive environments and various fields of life and civil use.

[0004] like Figure 1 The figure shows a flow chart of the pultrusion process. The pultrusion process is usually divided into the following steps: glass fiber roving arrangement - impregnation - preforming - extrusion molding and curing - traction - cutting - finished product. Impregnation is one of the key steps in the pultrusion process. In this process, the glass fiber roving or its spun material is pulled by an external force and first passes through the impregnation box to make the fiber soaked in resin glue. The purpose of this step is to enhance the mechanical properties of the material so that the product has higher strength and better durability. After impregnation, in order to give full play to the role of the reinforcing material and improve the strength of the product, the combination of fiber and resin can better withstand external forces, thereby improving the quality and performance of the final product.

[0005] In actual production applications, the temperature in the workshop is relatively low in winter, and the viscosity of the upper and lower layers of the rubber in the dipping box is different. After the untwisted glass fiber roving and other continuous reinforcing materials, polyester surface felt, etc. enter the dipping box, the rubber attached to the surface is uneven, which will lead to increased costs due to the excessive adhesion of the rubber, and the quality of the product cannot be guaranteed. Utility Model Content

[0006] The utility model provides a dipping device for composite material pultrusion equipment, which solves the defects in the prior art that the production cost is increased and the quality of the product cannot be guaranteed due to the different viscosities of the upper and lower layers of the rubber in the dipping box.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a dipping device for composite material pultrusion equipment, which comprises:

[0008] base plate;

[0009] A dipping box, the dipping box being fixed on the top of the bottom plate;

[0010] A support plate, the support plate being reciprocally movably disposed on top of the base plate;

[0014] Optimally, the stirring head includes stirring plates fixed at intervals on the stirring shaft, grooves arranged around the circumference of the stirring plates, and blades integrally connected between the stirring plates.

[0015] Optimally, the sealing assembly includes a slide groove opened on the side wall of the dipping box, sealing grooves opened on both sides of the slide groove, and a main sealing ring and a secondary sealing ring sleeved on the stirring shaft. The main sealing ring is arranged in the sealing groove, and the secondary sealing ring is arranged in the slide groove.

[0016] Optimally, the sealing assembly further comprises a baffle integrally connected to the circumference of the stirring shaft, and a first spring and a second spring sleeved on the stirring shaft, wherein the first spring and the second spring are located on both sides of the baffle.

[0017] Optimally, the driving assembly includes a rotating plate rotatably connected to the top of the base plate, a slide plate slidably connected to the top of the base plate, and connecting plates on both sides respectively rotatably connected to the rotating plate and the slide plate, and the support plate is fixed on the top of the slide plate.

[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0033] like Figure 2 、 3The figure shows a schematic diagram of a dipping device for composite material pultrusion equipment according to the present invention. It is typically used to stir the rubber material within the dipping box 2 to prevent uneven adhesion of the rubber material to the surface of the dipping box 2 when the ambient temperature of the pultrusion equipment is low. This can lead to increased costs and poor product quality due to uneven adhesion of the rubber material to the surface of the dipping box 2 after untwisted glass fiber roving, other continuous reinforcement materials, polyester surface felt, etc., after entering the dipping box 2. The dipping device includes a base plate 1, a dipping box 2, a drive assembly, a support plate 16, a stirring assembly, and a sealing assembly.

[0034] The base plate 1 is fixed on the pultrusion equipment by screws, and the dipping box 2 is fixed on the top of the base plate 1. The dipping box 2 is filled with glue. The glass fiber roving or its spun material is pulled by external force and first passes through the dipping box 2 to make the fiber soaked in resin glue.

[0035] The driving assembly is arranged on the top of the bottom plate 1, and is used to drive the stirring assembly to move back and forth in the dipping box 2, so as to ensure that the glue in the dipping box 2 is stirred more evenly, ensure that the viscosity of the glue in the dipping box 2 is consistent, reduce costs while ensuring the quality of the product.

[0036] The drive assembly includes a drive motor 3, a rotating plate 4, a first slide rail 5, a first slider 6, a first coupling column 7, a first limit plate 8, a coupling plate 9, a slide plate 10, a second coupling column 11, a second limit plate 12, a second slide rail 13, a second slider 14, and a spacer 15. The housing of the drive motor 3 is fixed to the lower surface of the base plate 1. The drive shaft of the drive motor 3 passes through the base plate 1 and is connected to the rotating plate 4. The drive motor 3 drives the rotating plate 4 to rotate.

[0037] The first slide rail 5 is annular and screwed to the top of the base plate 1. The first slider 6 is slidably mounted on the first slide rail 5 and fixed to the bottom of the rotating plate 4. Because the rotating plate 4 has a circular trajectory, the annular first slide rail 5 is provided to match the circular trajectory of the rotating plate 4. The coordinated arrangement of the first slide rail 5 and the first slider 6 improves the stability of the rotating plate 4 during rotation, preventing the rotating plate 4 from tilting during rotation and affecting the stirring of the rubber material in the dipping box 2.

[0038] The second slide rail 13 is fixed to the top of the base plate 1 by screw fastening, and is located between the rotating plate 4 and the dipping box 2. The second slider 14 is slidably installed on the second slide rail 13, and the slide plate 10 is fixed on the top of the second slider 14. By setting the second slide rail 13 and the second slider 14 that cooperate with each other, the stability of the reciprocating linear movement of the slide plate 10 can be improved, thereby improving the stirring effect of the rubber material in the dipping box 2.

[0039] The first coupling post 7 is fixed to the top of the rotating plate 4, and the second coupling post 11 is fixed to the top of the slide 10. Through holes are formed on both sides of the coupling plate 9, which are respectively mounted on the first coupling post 7 and the second coupling post 11 (the through holes in the coupling plate 9 form a hole-axis fit with the first coupling post 7 and the second coupling post 11). When the drive motor 3 drives the rotating plate 4 to rotate, the coupling plate 9 drives the slide 10 to perform reciprocating linear motion along the second slide rail 13, which in turn drives the stirring assembly to perform reciprocating linear motion within the dipping box 2, ensuring more uniform mixing of the rubber material within the dipping box 2 and preventing environmental factors from affecting the viscosity of the rubber material.

[0040] When the connecting plate 9 moves, in order to prevent the connecting plate 9 from falling off the first connecting column 7 or the second connecting column 11, after the connecting plate 9 is put on the first connecting column 7 and the second connecting column 11, the first limiting plate 8 is fixed on the first connecting column 7, and the second limiting plate 12 is fixed on the second connecting column 11. The first limiting plate 8 and the second limiting plate 12 are used to limit the connecting plate 9 axially (the diameter of the first limiting plate 8 is larger than the diameter of the first connecting column 7, and the diameter of the second limiting plate 12 is larger than the diameter of the second connecting column 11).

[0041] The pad 15 is fixed on the top of the slide 10, and the support plate 16 is fixed on the top of the pad 15. The pad 15 props up the support plate 16 to avoid interference between the support plate 16 and the connecting plate 9. When the rotating plate 4 drives the slide 10 to do reciprocating linear motion, it will simultaneously drive the support plate 16 to do reciprocating linear motion.

[0042] The stirring assembly is fixed on the top of the support plate 16 and passes through the dipping box 2, and is used to stir the glue in the dipping box 2. Figure 6 、 7 As shown, the stirring assembly includes a vertical plate 17, a rotary motor 18, a stirring shaft 19, and a stirring head. The vertical plate 17 is vertically fixed to the top of the support plate 16, and the rotary motor 18 is fixed to one side of the vertical plate 17. The output shaft of the rotary motor 18 is connected to the stirring shaft 19. The rotary motor 18 drives the stirring shaft 19 to rotate, and the stirring head then completes the stirring of the rubber material in the dipping box 2.

[0043] The mixing head includes a mixing plate 20, a groove 21, and blades 22. The mixing plates 20 are two in number and fixed to the side of the mixing shaft 19 away from the upright plate 17. The grooves 21 are arranged around the circumference of the mixing plate 20. The provision of the grooves 21 not only reduces the overall weight of the mixing head, facilitates the driving of the rotary motor 18, and saves energy; it also ensures that the rubber material is fully mixed and flows inside and outside the mixing head, improving the mixing effect of the rubber material.

[0044] The blade 22 is fixed between the two stirring plates 20, and the blade 22 is twisted into a "twisted" shape. The rotating motor 18 drives the stirring shaft 19 to rotate. When the blade 22 rotates, it stirs the glue in the dipping box 2, thereby ensuring that the viscosity of the glue in the dipping box 2 remains consistent.

[0045] like Figure 4 、 5 As shown, a sealing assembly is provided on the side wall of the dipping box 2 to seal the stirring shaft 19, preventing the stirring shaft 19 from dislodging the rubber material in the dipping box 2 during its reciprocating linear motion, thereby wasting the rubber material. The sealing assembly includes a chute 23, a sealing groove 24, a primary sealing ring 25, a secondary sealing ring 26, a baffle 27, a first spring 28, and a second spring 29. The chute 23 is provided in the side wall of the dipping box 2, and the sealing grooves 24 are provided on both sides of the chute 23. The diameter of the sealing grooves 24 is larger than that of the chute 23, so that a shoulder structure is formed at the junction of the chute 23 and the sealing grooves 24, preventing the sealing ring from being dislodged during the reciprocating motion of the stirring shaft 19.

[0046] The main sealing ring 25 and the auxiliary sealing ring 26 are integrally formed and sleeved on the stirring shaft 19. The main sealing ring 25 is arranged in the sealing groove 24, and the auxiliary sealing ring 26 is arranged in the slide groove 23. The main sealing ring 25 and the auxiliary sealing ring 26 are both made of rubber, relying on the deformability of rubber to improve the sealing effect.

[0047] The baffle 27 is integrally connected to the outer circumference of the stirring shaft 19 and is placed in the chute 23 . The first spring 28 and the second spring 29 are sleeved on the stirring shaft 19 and are respectively located on both sides of the baffle 27 .

[0048] When the stirring shaft 19 moves inward, the baffle 27 squeezes the first spring 28, and the first spring 28 deforms and presses against one set of secondary sealing rings 26. The secondary sealing rings 26 are squeezed by the elastic force of the first spring 28, thereby improving the sealing ability between the stirring shaft 19 and the dipping box 2 when the stirring shaft 19 moves inward;

[0049] When the stirring shaft 19 moves outward, the baffle 27 compresses the second spring 29. At this time, the first spring 28 returns to its original position to assist the outward movement of the baffle 27 and the stirring shaft 19. The second spring 29 deforms and presses against the other set of secondary sealing rings 26. The elastic force of the second spring 29 compresses the secondary sealing rings 26, thereby improving the sealing ability between the stirring shaft 19 and the dipping box 2 when the stirring shaft 19 moves outward.

[0050] The dipping box 2 is rectangular in shape, with a hollow interior for holding the rubber. The sidewall of the dipping box 2, where the stirring shaft 19 is mounted, is not a one-piece structure, but rather a spliced structure of two halves. Because the stirring shaft 19 is provided with a baffle 27, this spliced structure facilitates the installation of the stirring shaft 19 and avoids installation interference. The two halves are then bolted together.

[0051] The dipping device for composite material pultrusion equipment of the present invention drives the support plate 16 to perform reciprocating linear motion by setting a driving component, thereby driving the stirring component to perform reciprocating linear motion in the dipping box 2, ensuring that the rubber material in the dipping box 2 is stirred more evenly, avoiding the occurrence of stirring blind spots, ensuring that the viscosity of the rubber material in the dipping box 2 is consistent, reducing costs while ensuring the quality of the product.

[0052] The setting of the sealing component can prevent the stirring shaft 19 from bringing out the rubber material in the dipping box 2 during the reciprocating linear motion, thereby avoiding waste of the rubber material.

[0053] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
