Description

Technical Field

[0001] This utility model relates to the field of polyurethane technology, and in particular to a casting-type continuous polyurethane production equipment. Background Technology

[0002] Polyurethane, short for polyurethane, is a high molecular weight compound. Cast polyurethane is generally prepared by mixing and reacting a prepolymer (component A) and a chain extender (component B). The preparation of the prepolymer requires the reaction of isocyanate and polyol, and the entire preparation process takes at least three hours in a reactor. The chain extender is an alcohol or amine substance. Although it does not undergo a chemical reaction, it still requires at least one hour of dehydration and vacuum pretreatment before use.

[0003] Chinese Patent CN218139368U discloses a continuous polyurethane casting production equipment, including a support platform. Two A-material reactors are fixedly installed on the top of the support platform near the rear surface. In this invention, when the A-material reactor and the B-material reactor are in use, only one reactor switch is open, while the other reactor switches are closed. Normal casting uses one of the A-material reactors and one of the B-material reactors. When the raw materials are almost used up, the raw materials are prepared in advance in the other A-material reactor and the equipment can be directly switched to the prepared reactor. The metered raw materials are mixed at the agitator and finally flow out from the casting port for use. Only the valve switch needs to be switched to allow continuous casting without stopping the equipment to prepare the raw materials, thus achieving a rapid material supply effect and improving work efficiency.

[0004] In existing continuous polyurethane production equipment, raw materials are discharged from the reactor via a casting pipe. However, the vibration function of the reactor is not readily available during material discharge, resulting in poor material discharge and consequently reducing continuous production efficiency and the overall effectiveness of the continuous polyurethane production equipment.

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] Example 1

[0024] like Figure 1 - Figure 3 As shown, the present invention proposes a continuous polyurethane casting production equipment, comprising: a base 1, a reactor 2, a vibration assembly 3, a buffer tank body 4, and a housing 5; the base 1 is connected to the reactor 2, and the vibration assembly 3 is connected to the periphery of the reactor 2; the vibration assembly 3 includes a support plate 301, a vibration motor 302 connected below the support plate 301 and a telescopic rod 303 connected thereto, an inclined plate 304 connected above the support plate 301, a sleeve 305 connected to the inclined plate 304, and the sleeve 305 is connected to the periphery of the reactor 2; the inclined plate 304 is connected to a connector; the buffer tank body 4 is connected to the base 1, and the housing 5 is connected to the base 1; the connector includes a connecting plate 306 connected to the inclined plate 304, a rod 307 connected to the connecting plate 306, and the rod 307 is connected to the inside of a fixed rod 308 through an open end. By using the vibration assembly 3, the reactor 2 can be made to vibrate, which can improve the discharge effect of raw materials in the reactor 2, thereby avoiding the sedimentation of raw materials inside the reactor 2, improving the quality and production efficiency of polyurethane casting, and conveniently improving the practicality of the continuous production equipment for cast polyurethane. The vibration assembly 3 is equipped with a telescopic rod 303, which includes a sliding rod, a sliding part, a fixed cylinder, and a spring. One end of the sliding rod is hinged to the support plate 301, and the other end of the sliding rod slides into the fixed cylinder and connects to the sliding part. The sliding part slides to the inner wall of the fixed cylinder. The spring is located inside the fixed cylinder and sleeved on the outside of the sliding rod. The two ends of the spring are respectively connected to the inner wall of the fixed cylinder and the sliding part. The fixed cylinder is connected to the base 1 for use in conjunction with the vibration motor 302. The rod body 307 and the fixed rod 308 are connected to form a telescopic mechanism. The use of the telescopic rod 303, the rod body 307, and the fixed rod 308 can conveniently improve the vibration stability and improve the practicality of the continuous production equipment for cast polyurethane.

[0025] To further explain, four reactors 2 and four vibration components 3 are provided, with each of the four vibration components 3 connected to one of the four reactors 2. The four reactors 2 facilitate continuous polyurethane production casting, thus improving casting efficiency.

[0026] To further explain, the discharge ends of the four reactors 2 are respectively connected to telescopic pipes 201, which are connected to discharge pipes 202, and the discharge pipes 202 are connected to the buffer tank body 4. A switch is installed in each reactor 2 to control the discharge and casting of raw materials. The telescopic pipes 201 are used in conjunction with the vibration of the reactors 2, facilitating the use of components in the continuous polyurethane casting production equipment and improving the efficiency of the equipment.

[0027] Example 2

[0028] like Figure 2 As shown, this utility model proposes a continuous production equipment for casting type polyurethane. Based on the above embodiments, this embodiment also details the specific components of the buffer tank body 4 and the box body 5, as well as their assembly method.

[0029] To further explain, the buffer tank body 4 is connected to the conveying pipe 401, and the conveying pipe 401 is connected to a buffer tank switch, which is used to control the opening or closing of the buffer tank body 4. The raw material is conveyed into the buffer tank body 4 through the telescopic pipe 201 and the discharge pipe 202. The buffer tank body 4 facilitates the buffering of the raw material and allows the four reaction vessels 2 to be combined in pairs and connected to the buffer tank body 4 for use, thus conveniently increasing the continuous production of polyurethane and ensuring a stable supply of raw materials.

[0030] Further explanation: The housing 5 is connected to a servo motor 501. The drive end of the servo motor 501 is connected to a rotating shaft, which runs through the interior of the mixer 502 and is connected to a mixing roller. The mixer 502 is connected to a connecting pipe 503, which is connected to a metering pump 504. The mixer 502 is also connected to a pouring pipe 505, which runs through the housing 5 and connects to the outside. A conveying pipe 401 runs through the housing 5 and connects to the metering pump 504. When raw materials are metered and conveyed into the mixer 502, the servo motor 501 is started. The drive end of the servo motor 501 causes the rotating shaft to rotate, which in turn drives the mixing roller. The mixing roller stirs the raw materials inside the mixer 502, facilitating the uniformity of the poured materials and improving the casting quality of continuous polyurethane production, thus enhancing the usability of the casting-type continuous polyurethane production equipment.

[0031] The working principle of this utility model is as follows: Polyurethane raw materials are added into four reaction vessels 2 for casting. The reaction vessels 2 are opened or closed according to the casting process. When a reaction vessel 2 is in use, the corresponding connected vibration motor 302 is activated. The vibration motor 302 causes the support plate 301 to vibrate, which in turn drives the inclined plate 304, which in turn drives the sleeve 305, which in turn drives the reaction vessel 2. The vibration of the reaction vessel 2 facilitates the discharge of raw materials, thus improving the discharge efficiency. This improves the efficiency and prevents raw materials from settling in the reactor 2, facilitating the discharge and transportation of polyurethane raw materials from the reactor 2. The raw materials are transported to the buffer tank body 4 through the telescopic pipe 201 and the discharge pipe 202. The buffer tank body 4 is connected to the conveying pipe 401. By controlling the buffer tank switch, the raw materials are transported to the metering pump 504 through the conveying pipe 401. The metering pump 504 facilitates the quantitative delivery of the polyurethane raw materials. The raw materials are then transported to the agitator 502 and continuously used in the production of polyurethane through the casting pipe 505, facilitating the use of the casting-type continuous polyurethane production equipment.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
