Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically a stirring device for polyurethane production. Background Technology

[0002] Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or by slight cross-linking between macromolecular chains. These two cross-linking structures are reversible as the temperature rises or falls. In the molten or solution state, the intermolecular forces weaken, but after cooling or solvent evaporation, strong intermolecular forces reconnect them, restoring the original solid properties.

[0003] According to a public announcement (Announcement No.: CN211566549U) of a mixing device for the production of thermoplastic polyurethane elastomers, the mixing device for the production of thermoplastic polyurethane elastomers described in the above application is equipped with reinforcing parts and shims, and the mixing mechanism is relatively independent from the mixing drum. During the mixing process, the hydraulic column descends, causing the cover plate to cover the upper end of the mixing drum. The motor drives the mixing rod to rotate and mix. When the mixture is removed, the hydraulic column rises, disengaging the cover plate and the mixing rod from the inside of the mixing drum. The insertion rod is then pulled out from the insertion hole, which pushes the mixing drum forward and slides out, facilitating the pouring of the mixture and improving the discharge efficiency.

[0004] However, in actual use, due to the properties of the raw materials themselves, the above-mentioned equipment is prone to forming adhesion between the inner walls or between each other. Therefore, the traditional practice of opening a discharge port at the bottom of the mixing device results in slow and difficult discharge of the mixture. In view of this, we propose a mixing device for polyurethane production. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for polyurethane production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stirring device for polyurethane production, comprising a mounting platform, a support fixedly mounted on the upper surface of the mounting platform, a stirring assembly disposed on the surface of the support, a stirring tank disposed on the upper surface of the mounting platform, a tilting mechanism disposed on the upper surface of the mounting platform, and an auxiliary mechanism disposed on the upper surface of the mounting platform, the tilting mechanism comprising: A straight rod is fixedly installed on the inner wall of the mounting platform. A torsion spring is fixedly installed on the arc surface of the straight rod, and the end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the mounting plate. A baffle is fixedly installed on the arc surface of the mixing tank, and a guide rod is fixedly installed on the surface of the baffle. A limit plate is fixedly installed on the upper surface of the mounting platform.

[0007] Preferably, the auxiliary mechanism includes a groove formed on the side wall of the mounting platform, and a fixing rod is provided inside the groove.

[0008] Preferably, the fixing rod can pass through one side of the mounting platform, thereby limiting the stability of the mixing tank when it is tilted to a certain angle.

[0009] Preferably, the inner wall of the limiting plate is provided with a guide rod, so that the guide rod can move along the inner wall of the limiting plate.

[0010] Preferably, the side wall of the mounting plate has a circular hole, and the mounting plate is fitted onto the arc surface of the straight rod, so that the mounting plate can rotate around the straight rod.

[0011] Preferably, a positioning plate is fixedly installed on the upper surface of the mounting plate, and a positioning plate is fixedly installed on the surface of the mixing tank, so that the mixing tank is fixedly installed on the surface of the mounting plate through the positioning plate.

[0012] Preferably, there are two limiting plates, which are arranged in a mirror image on both sides of the mixing tank, so that the mixing tank can be lifted from both sides and the raw materials inside the mixing tank can be poured out.

[0013] Compared with the prior art, the present invention provides a stirring device for polyurethane production, which has the following beneficial effects: 1. This mixing device for polyurethane production is equipped with a tilting mechanism. After the raw materials are mixed, two ends of the baffle lift from both sides to tilt the mixing tank. The mounting plate rotates on the surface of the straight rod, and the torsion spring deforms, which to a certain extent counteracts the force exerted on the mixing tank during movement, ensuring the stability of the mixing tank during tilting. At the same time, the guide rod moves along the limiting plate to ensure the stability of the mixing tank during tilting, thereby facilitating the pouring of the raw materials inside the mixing tank.

[0014] 2. This mixing device for polyurethane production is equipped with an auxiliary mechanism and a groove. When tilted at a certain angle, the fixing rods on both sides can pass through the groove on the mounting platform to limit the lower end of the mounting plate of the mixing tank when it is tilted at a certain angle. This limits the mixing tank and makes it convenient for workers to collect the raw materials remaining on the inner wall of the mixing tank using tools, ensuring the discharge of raw materials from the mixing tank.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a stirring device for polyurethane production, including a mounting platform 1, a bracket 2 fixedly mounted on the upper surface of the mounting platform 1, a stirring assembly 5 disposed on the surface of the bracket 2, a stirring tank 6 disposed on the upper surface of the mounting platform 1, a tilting mechanism 3 disposed on the upper surface of the mounting platform 1, and an auxiliary mechanism 4 disposed on the upper surface of the mounting platform 1. The tilting mechanism 3 includes a straight rod 301, a torsion spring 302, a mounting plate 303, a baffle 304, a guide rod 305, and a limiting plate 306.

[0018] In one embodiment of this utility model, a straight rod 301 is fixedly installed on the inner wall of the mounting platform 1, a torsion spring 302 is fixedly installed on the arc surface of the straight rod 301, one end of the torsion spring 302 away from the arc surface of the straight rod 301 is fixedly connected to the inner wall of the mounting plate 303, a baffle 304 is fixedly installed on the arc surface of the mixing tank 6, a guide rod 305 is fixedly installed on the surface of the baffle 304, and a limit plate 306 is fixedly installed on the upper surface of the mounting platform 1.

[0019] In addition, the auxiliary mechanism 4 includes a groove 401, which is formed on the side wall of the mounting platform 1. A fixing rod 402 is provided inside the groove 401. The fixing rod 402 can pass through one side of the mounting platform 1, thereby limiting the stability of the mixing tank 6 when it is tilted to a certain angle.

[0020] In this embodiment of the invention, a guide rod 305 is provided on the inner wall of the limiting plate 306, allowing the guide rod 305 to move along the inner wall of the limiting plate 306. A circular hole is provided on the side wall of the mounting plate 303, and the mounting plate 303 is fitted onto the arc surface of the straight rod 301, allowing the mounting plate 303 to rotate around the straight rod 301. A positioning plate is fixedly mounted on the upper surface of the mounting plate 303, and a positioning plate is fixedly mounted on the surface of the mixing tank 6, so that the mixing tank 6 is fixedly mounted on the surface of the mounting plate 303 via the positioning plate. There are two limit plates 306, which are arranged in a mirror image on both sides of the mixing tank 6 to facilitate lifting the mixing tank 6 from both sides and pouring the raw materials inside the mixing tank 6. The mixing assembly 5 includes a telescopic cylinder fixedly installed on the upper surface of the support 2. A placement frame is fixedly installed on the movable end of the telescopic cylinder. A motor is fixedly installed on the inner wall of the placement frame. A stirring rod is fixedly installed on the output end of the motor. A stabilizing plate is installed on the surface of the placement frame. A round rod passes through the surface of the stabilizing plate and limits the stabilizing plate to ensure the overall stability of the placement frame.

[0021] In this invention, when in use, the raw materials are prepared and mixed. Then, two baffles 304 are lifted from both sides to tilt the mixing tank 6. The mounting plate 303 rotates on the surface of the straight rod 301, and the torsion spring 302 deforms, which to a certain extent cancels out the force when the mixing tank 6 moves, ensuring that the raw materials are poured out slowly when the mixing tank 6 is tilted. At the same time, the guide rod 305 moves along the limiting plate 306 to ensure the stability of the tilting of the mixing tank 6, thereby facilitating the pouring of the raw materials inside the mixing tank 6.

[0022] Furthermore, a groove 401 is provided. When tilted at a certain angle, the fixing rods 402 on both sides can pass through the groove 401 on the mounting platform 1 to limit the lower end of the mounting plate 303 of the mixing tank 6 when tilted at a certain angle. This limits the mixing tank 6 and makes it convenient for workers to collect the raw materials remaining on the inner wall of the mixing tank 6 using tools, ensuring the discharge of raw materials from the mixing tank 6.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
