Description

Technical Field

[0001] The utility model relates to the field of epoxy resin processing, in particular to a rapid cooling device for modified epoxy resin. Background Art

[0002] Epoxy resin is a high molecular polymer with the molecular formula (C11H12O3)n. It is a general term for a class of polymers containing two or more epoxy groups in the molecule. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, cured and cross-linked to form a network structure, so it is a thermosetting resin. Bisphenol A type epoxy resin not only has the largest output and the most complete varieties, but also new modified varieties are still increasing and the quality is constantly improving.

[0003] For example, the patent document with the announcement number CN219968594U discloses a rapid cooling device for modified epoxy resin processing, in which the epoxy resin is discharged into the interior of the first spiral groove through the feed port, and the epoxy resin flows inside the first spiral groove for preliminary heat dissipation. The fan blades are driven to rotate by the acceleration component to accelerate the air circulation inside the box body, and the epoxy resin is further cooled. However, the epoxy resin in this scheme flows through the groove body, and the flow rate is greatly limited, especially the viscous fluid cannot be accelerated by external pressurization. Utility Model Content

[0004] The purpose of the utility model is to provide a rapid cooling device for modified epoxy resin in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 - Figure 4 As shown, a rapid cooling device for modified epoxy resin includes a cooling pool 100, wherein a coolant is arranged inside the cooling pool 100, a cooling mechanism is arranged on the cooling pool 100, the cooling mechanism includes a cooling component distributed in an array, the cooling component includes a U-shaped cooling pipe 203, a heat conducting sheet 204 distributed in a circular array is fixedly connected to the middle of the U-shaped cooling pipe 203, a ring body 205 is arranged on one side of the heat conducting sheet 204, the ring body 205 is rotatably connected to the U-shaped cooling pipe 203, a fan blade 206 distributed in a circular array is fixedly connected to one side of the ring body 205 close to the heat conducting sheet 204, and symmetrically distributed heat dissipation adjustment mechanisms are arranged on the left and right sides of the top of the cooling pool 100.

[0025] The U-shaped cooling tube 203 guides the epoxy resin into the coolant, the heat conductive sheet 204 is used to increase the contact area with the coolant, so that the heat dissipation and cooling are faster, and the ring body 205 is used to keep the fan blades 206 rotatable. When the fan blades 206 rotate, the coolant around the heat conductive sheet 204 is driven to flow, so that the coolant can take away excess heat in time, making the cooling more uniform.

[0026] The cooling assembly also includes a motor 210, which is fixedly connected to the U-shaped cooling tube 203. The output shaft of the motor 210 is fixedly connected to a sprocket 208. The end of the ring body 205 away from the fan blades 206 is fixedly connected to a chain ring 207. The outer sides of the chain ring 207 and the sprocket 208 are meshed with a chain 209.

[0027] The motor 210 provides a rotational power to drive the sprocket 208 to rotate, drives the chain ring 207 to rotate through the chain 209, and finally drives the ring body 205 and the fan blades 206 to rotate.

[0028] The cooling mechanism includes two collecting pipes 202 . An L-shaped pipe 201 is inserted in the middle of the top surface of the collecting pipe 202 . Both ends of a U-shaped cooling pipe 203 are inserted in the bottom of the collecting pipe 202 .

[0029] The collecting pipe 202 connects a plurality of U-shaped cooling pipes 203 together. The L-shaped pipe 201 on one side is used for the inflow of epoxy resin, and the L-shaped pipe 201 on the other side is used for the outflow of epoxy resin.

[0030] The heat dissipation adjustment mechanism includes two U-shaped plates 301, which are arranged on the outside of the collecting pipe 202. The two ends of the U-shaped plate 301 are fixedly connected to the collecting pipe 202. Bidirectional threaded rods 302 are provided on the left and right sides of the top of the cooling pool 100. The bidirectional threaded rods 302 are rotatably connected to the cooling pool 100, and connecting rod assemblies are provided at both ends of the bidirectional threaded rods 302.

[0031] The U-shaped plate 301 is used to connect the connecting rod assembly, and the rotation of the bidirectional threaded rod 302 can control the sliders 304 on both sides to move closer to or away from each other.

[0032] The connecting rod assembly includes a slider 304 , which is threadedly connected to the front and rear sides of the bidirectional threaded rod 302 , and the slider 304 is slidably connected to the cooling pool 100 . The slider 304 is hinged with a connecting rod 303 , and the connecting rod 303 is hinged to the U-shaped plate 301 .

[0033] When the sliders 304 are close to each other, the top of the connecting rod 303 is driven to push up the U-shaped plate 301. When the sliders 304 are away from each other, the top of the connecting rod 303 is driven to pull the U-shaped plate 301 downward. When moving downward, the depth of immersion of the U-shaped cooling tube 203 in the coolant deepens. When the flow rate in the tube is faster, it can still be immersed in the coolant for a longer time, thereby achieving a better cooling effect.

[0034] The rear end of the bidirectional threaded rod 302 is fixedly connected with a pulley 305 , the outer belt link of the pulley 305 is connected with a belt 306 , and the front end of the bidirectional threaded rod 302 is provided with a knob 307 .

[0035] The belt 306 is used to keep the pulley 305 rotating synchronously, thereby driving the rotation of the bidirectional threaded rod 302 . The rotation of the bidirectional threaded rod 302 drives the movement of the slider 304 . The knob 307 facilitates manual control of the rotation of the bidirectional threaded rod 302 .

[0036] Working principle:

[0037] The epoxy resin enters the collecting pipe 202 from the L-shaped tube 201 on one side, and then enters multiple U-shaped cooling tubes 203. The U-shaped cooling tubes 203 are immersed in the coolant in the cooling pool 100. The heat conductive sheet 204 takes away most of the heat in the epoxy resin, and the epoxy resin cools down quickly. At the same time, the motor 210 drives the sprocket 208 to rotate. The sprocket 208 drives the chain ring 207 to rotate through the chain 209, and then drives the ring body 205 and the fan blades 206 to rotate. The fan blades 206 blow away the coolant near the heat conductive sheet 204, so that the local temperature of the coolant is more uniform and the cooling effect is better.

[0038] As external pressure is applied, the flow rate of the epoxy resin inside the U-shaped cooling tube 203 is accelerated, the time the epoxy resin stays in the coolant becomes shorter, and the cooling effect is poor. Therefore, the knob 307 is manually rotated to drive the bidirectional threaded rod 302 to rotate. The two bidirectional threaded rods 302 rotate synchronously through the pulley 305 and the belt 306. The sliders 304 on both sides drive the U-shaped plate 301 on the same side to descend through the connecting rod 303, causing the collecting tube 202 to descend. The immersion depth of the U-shaped cooling tube 203 in the coolant increases, which increases the time the epoxy resin stays in the coolant and achieves a better cooling effect.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
