Description

Technical Field

[0001] This utility model belongs to the field of polyurethane color paste pultrusion technology, and particularly relates to a polyurethane color paste device for pultrusion molding. Background Technology

[0002] Polyurethane color paste is an industrial paint composed of polyurethane resin, pigments, additives, and solvents. Its main components include polyurethane resin, diluents, additives, and pigments. These components endow polyurethane color paste with high molecular weight heat resistance and high chemical stability. Polyurethane color paste requires pultrusion molding during processing. Pultrusion molding of polyurethane color paste is a process of making polyurethane color paste into products of specific shapes and sizes through pultrusion molding. However, existing pultrusion molding equipment cannot perform proportioning, which affects the quality after plasticization. Therefore, a polyurethane color paste device for pultrusion molding is proposed.

[0003] For example, Chinese patent CN222554202U discloses a discharge device for polyurethane pultrusion molding, relating to the field of discharge device structure technology. It addresses the problem that existing discharge devices have simple structures but result in low efficiency during polyurethane pultrusion molding. A transmission device box is installed above the support frame, a motor is installed below the transmission device box, a support frame is installed on one side of the transmission device box, a discharge conveying pipe is installed above the support frame, and an insulation device is installed on the outside of the discharge conveying pipe.

[0004] The aforementioned patent has the following problems:

[0005] In contrast to existing technologies where polyurethane is not properly proportioned before pultrusion, potentially leading to incomplete molding and inaccurate polyurethane colorant ratios that could affect post-molding quality and reduce practicality, current technologies also lack heat dissipation for the polyurethane colorant after pultrusion, requiring workers to wait and disrupting subsequent polyurethane molding and pultrusion processes. Therefore, we propose a polyurethane colorant device for pultrusion. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a polyurethane color paste device for pultrusion molding, which achieves the effects of proportioning the color paste before pultrusion molding and heat dissipation after pultrusion molding.

[0007] In view of this, the present invention provides a polyurethane color paste device for pultrusion molding, including a mixing tank, and further comprising: an end cover movably mounted on the top of the mixing tank, a through hole being formed inside the end cover, a protective layer being fixedly disposed inside the mixing tank, a rotating rod being movably mounted inside the through hole, a vertical plate being fixedly mounted on one side of the mixing tank, a top plate being fixedly mounted on the top of the vertical plate, a motor being fixedly mounted on the top of the top plate, a fan being fixedly mounted on the output end of the motor, water tanks being fixedly mounted on both sides of the motor, and a high-pressure nozzle being fixedly disposed at the bottom of the water tank.

[0008] Based on the above structure, the polyurethane color paste raw material is collected through a mixing tank, which is then protected by a protective layer to prevent corrosion. After the polyurethane color paste is poured in, the mixing tank is covered by an end cap. A through-hole allows the rotating rod to be fixed to the top of the mixing tank. The operator then rotates the rotating rod to stir and fully mix the polyurethane color paste raw material. This allows for proper mixing before pultrusion molding, preventing mold failure and ensuring the quality of the molded product, thus increasing practicality. A vertical plate is used to fix the top plate. When heat dissipation is needed, the operator opens the mold, and a motor drives a fan to rotate. Water is then heated in a water tank, and a water pump draws the water from inside the pipes to a high-pressure pump. The high-pressure nozzle atomizes and sprays water, which is then moved downwards by a fan. Because the high-pressure nozzle atomizes the water, it is sprayed out in a mist state, preventing water droplets from falling onto the mold. This cools the air near the fan, which then blows the cool air to the top of the mold, further cooling the polyurethane colorant. The water sprayed from the high-pressure nozzle falls onto the polyurethane colorant without damaging the mold, facilitating faster heat dissipation. When used in conjunction with the high-pressure nozzle, the polyurethane colorant can dissipate heat after pultrusion molding, allowing workers to remove it promptly without waiting, thus not interfering with the subsequent plasticization and pultrusion processes.

[0009] Preferably, a workbench is movably installed at the bottom of the mixing tank, and a support plate is fixedly installed at the bottom of each workbench. A bracket is fixedly installed between the support plates, and the workbench can collect the mixing tank.

[0010] Preferably, a cylinder is fixedly installed on one side of the upright plate, and a clamping component is fixedly installed on the output end of the cylinder, which facilitates the pulling of the agent.

[0011] Preferably, a protective sleeve is movably mounted on the surface of the cylinder, and a protective cover is movably mounted on one side of the protective sleeve. The protective cover has heat dissipation holes that penetrate through it, and the protective sleeve facilitates the protection of the cylinder.

[0012] Preferably, a mold is fixedly installed at the bottom of the fan, an installation component is fixedly installed on the other side of the mold, a heating tube is fixedly installed inside the mold, and the mold is capable of plasticizing polyurethane pigment.

[0013] Preferably, reinforcing plates are fixedly installed on both sides of the bracket. The reinforcing plates are made of stainless steel and support the worktable.

[0014] Preferably, a water pump is fixedly installed on the top of the high-pressure nozzle, which facilitates water pumping.

[0015] The beneficial effects of this utility model are:

[0016] 1. This polyurethane color paste device for pultrusion can collect the polyurethane color paste raw material using a mixing tank. The mixing tank is then protected by a protective layer to prevent corrosion. After the polyurethane color paste is poured in, the mixing tank is covered by an end cap. A through-hole allows the rotating rod to be fixed to the top of the mixing tank. The operator then rotates the rotating rod to stir and fully mix the polyurethane color paste raw material. This device allows for proportioning before pultrusion, preventing mold failure and ensuring the quality of the final product, thus increasing its practicality.

[0017] 2. This polyurethane color paste device for pultrusion molding can fix the top plate using a vertical plate. When heat dissipation is needed, the operator opens the mold, the motor drives the fan to rotate, and then heats water in the water tank. The water is then pumped from the water pipe to the high-pressure nozzle, which atomizes the water and sprays it out. The fan then moves the atomized water downwards. Because the water is atomized by the high-pressure nozzle, it is sprayed out in a mist state, preventing water droplets from falling onto the mold. This cools the air near the fan, and the fan blows the cool air to the top of the mold to cool the polyurethane color paste with good plasticity. The water sprayed from the high-pressure nozzle falls onto the polyurethane color paste with good plasticity without damaging the mold, which facilitates and accelerates the heat dissipation process. When used in conjunction with this device, the polyurethane color paste can be cooled after pultrusion molding, allowing the operator to remove it in time without waiting, and without delaying the normal plasticization and pultrusion process of the polyurethane color paste.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This application discloses a polyurethane color paste apparatus for pultrusion molding. Please refer to [link to relevant documentation]. Figures 1-4 The system includes a mixing tank 1, and further includes: an end cover 101 movably mounted on the top of the mixing tank 1, a through hole 102 extending through the interior of the end cover 101, a protective layer 103 fixedly installed inside the mixing tank 1, a rotating rod 104 movably mounted inside the through hole 102, a vertical plate 2 fixedly mounted on one side of the mixing tank 1, a top plate 201 fixedly mounted on the top of the vertical plate 2, a motor 202 fixedly mounted on the top of the top plate 201, a fan 203 fixedly mounted on the output end of the motor 202, water tanks 204 fixedly mounted on both sides of the motor 202, and a high-pressure nozzle 205 fixedly mounted on the bottom of the water tank 204.

[0026] Based on the above structure, the raw materials of polyurethane color paste can be collected using the mixing tank 1. The mixing tank 1 is then protected by the protective layer 103 to prevent corrosion. After the polyurethane color paste is poured in, the mixing tank 1 is covered by the end cap 101. The through hole 102 allows the rotating rod 104 to be fixed to the top of the mixing tank 1. The operator then rotates the rotating rod 104 to stir and fully mix the polyurethane color paste raw materials. This allows for proper mixing before pultrusion molding, preventing mold 6 from failing to form properly and ensuring the quality after molding, thus increasing practicality. The top plate 201 is then fixed using the upright plate 2. When heat dissipation is needed, the operator opens the mold 6, and the motor 202 drives the fan 203 to rotate. Water is then heated in the water tank 204, and a water pump pumps the water from the water pipe. The high-pressure nozzle 205 is drawn into the mold, atomizing water and spraying it out. The fan 203 then moves the atomized water downwards. Because the high-pressure nozzle 205 atomizes the water, the water is sprayed out in a mist state, preventing water droplets from falling onto the mold 6. This cools the air near the fan 203, which then blows the cool air to the top of the mold 6, further cooling the polyurethane colorant. The water sprayed from the high-pressure nozzle 205 falls onto the polyurethane colorant without damaging the mold 6, facilitating faster heat dissipation. When used in conjunction with this process, the polyurethane colorant can dissipate heat after pultrusion molding, allowing workers to remove it promptly without waiting, thus not interfering with the subsequent plasticization and pultrusion processes.

[0027] In one embodiment, a workbench 3 is movably mounted on the bottom of the mixing tank 1, and a support plate 301 is fixedly mounted on the bottom of each workbench 3. A bracket 302 is fixedly mounted between the support plates 301.

[0028] Specifically, the mixing box 1 can be placed on the workbench 3, then supported by the support plate 301, and then supported by the bracket 302.

[0029] In this embodiment, the support plate 301 can enhance stability.

[0030] In one embodiment, a cylinder 4 is fixedly installed on one side of the upright plate 2, and a clamping assembly 401 is fixedly installed on the output end of the cylinder 4.

[0031] Specifically, the clamping component 401 can be fixed by the cylinder 4. The clamping component 401 can clamp the scrap material after the polyurethane color paste is plasticized, which is convenient for pultrusion.

[0032] In this embodiment, since the material enters the mold 6 by extrusion, and then through a hole set on one side of the mold 6, the excess material will flow out from the hole during extrusion, forming scrap. Then, the cylinder 4 is activated to drive the clamping plate to move towards the hole of the mold 6. The clamping plate pulls up the scrap of material and stretches the material into shape. After forming, only some scrap needs to be trimmed.

[0033] In one embodiment, a protective sleeve 5 is movably mounted on the surface of the cylinder 4, and a protective cover 501 is movably mounted on one side of the protective sleeve 5. A heat dissipation hole 502 is provided through the interior of the protective cover 501.

[0034] Specifically, the cylinder 4 can be protected by the protective cover 5, the protective cover 501 covers the protective cover 5, and then the heat dissipation is carried out through the heat dissipation hole 502.

[0035] In this embodiment, the protective cover 501 can also be opened to facilitate the maintenance of cylinder 4.

[0036] In one embodiment, a mold 6 is fixedly installed at the bottom of the fan 203, an mounting component 601 is fixedly installed on the other side of the mold 6, and a heating tube 602 is fixedly installed inside the mold 6.

[0037] Specifically, polyurethane pigment can be placed in mold 6, and then mold 6 can be heated by heating tube 602 to facilitate plasticization. Then, mold 6 can be fixed by mounting part 601.

[0038] In this embodiment, mold 6 can be opened, and polyurethane pigment can be added by opening the top cover of mold 6.

[0039] In one embodiment, reinforcing plates 7 are fixedly installed on both sides of the bracket 302, and the reinforcing plates 7 are made of stainless steel.

[0040] Specifically, the support plate 301 can be supported by the reinforcing plate 7.

[0041] In this embodiment, stainless steel is used to strengthen the reinforcing plate 7 and improve its service life.

[0042] In one embodiment, a water pump is fixedly mounted on the top of the high-pressure nozzle 205.

[0043] Specifically, a water pump can be used to extract water from the 204 water tank for convenient heat dissipation.

[0044] In this embodiment, the water pump is used in conjunction with the water pipe to enhance heat dissipation efficiency.

[0045] In this embodiment, the polyurethane color paste device for pultrusion molding allows the mixing tank 1 to be placed on the workbench 3, supported by the support plate 301, and then supported by the bracket 302. The support plate 301 is further supported by the reinforcing plate 7. The mixing tank 1 can collect the raw materials of the polyurethane color paste, and the protective layer 103 protects the mixing tank 1 from corrosion. After the polyurethane color paste is poured in, the end cap 101 covers the mixing tank 1. The through hole 102 allows the rotating rod 104 to be fixed to the top of the mixing tank 1. The operator then rotates the rotating rod 104 to stir and mix the polyurethane color paste raw materials thoroughly. The top plate 201 is then fixed by the upright plate 2. When heat dissipation is required, the operator opens the mold 6, and the motor 202 drives the fan 203 to rotate. Then, hot water is added to the water tank 204, and the water is pumped from the water pipe to the high-pressure nozzle 205 by the water pump. The high-pressure nozzle 205 atomizes the water. The water is then moved downwards by the fan 203. Because the water can be atomized and sprayed out by the high-pressure nozzle 205, the water is sprayed out in a mist state, which will not produce water droplets falling on the mold 6, thus cooling the air near the fan 203. Then, the fan 203 blows the cool air to the top of the mold 6 to cool the well-plasticized polyurethane pigment. The water sprayed by the high-pressure nozzle 205 falls on the well-plasticized polyurethane pigment without damaging the mold 6. The water in the water tank 204 can be pumped out by the water pump to facilitate heat dissipation. Next, the cylinder 4 is protected by the protective sleeve 5 and the protective cover 501 covers the protective sleeve 5. Then, heat dissipation is carried out through the heat dissipation hole 502. Then, the clamping component 401 is fixed by the cylinder 4. The clamping component 401 can clamp the scrap material after the polyurethane pigment is plasticized. Then, the polyurethane pigment is placed in the mold 6, and the heating tube 602 is used to heat the mold 6 to facilitate plasticization. Finally, the mold 6 is fixed by the mounting part 601.
