Description

Technical Field

[0001] The present application relates to the technical field of thermoplastic elastomer manufacturing, and in particular to a device for rapid cooling of thermoplastic elastomer. Background Art

[0002] Thermoplastic elastomers are materials made from one or more polymer compounds through a specific manufacturing process. They have the properties of both rubber and plastic, exhibiting the elasticity of rubber while being able to be plasticized and molded at high temperatures. This characteristic makes thermoplastic elastomers widely used in many fields, such as automotive manufacturing, electronics and electrical engineering, construction, and medical care.

[0003] The Chinese utility model patent with publication number CN219634308U discloses a thermoplastic elastomer rapid cooling device, including a water tank, wherein a separation component is arranged inside the water tank, the separation component includes a vertical plate, the upper surface of the vertical plate is fixedly connected to a horizontal plate, the side wall of the vertical plate abuts the side wall of the water tank, and the lower surface of the horizontal plate abuts the upper surface of the water tank, and a plurality of mounting grooves are equidistantly provided on the upper surface of the horizontal plate, the interior of the mounting groove is slidably connected to a partition, and the upper surface of the partition is fixedly connected to the mounting plate. By setting up the separation component, multiple strips of thermoplastic elastomer can be separated during use to prevent the strips of thermoplastic elastomer from sticking together due to excessive temperature during transportation.

[0004] However, the separation assembly of the thermoplastic elastomer rapid cooling device still requires manual operation to separate the thermoplastic elastic strips during use. Furthermore, the separation assembly must be removed each time to make way for the thermoplastic elastic strips, and then installed on the water tank to press and separate the elastic strips. Alternatively, the separation assembly must be retained and the elastic strips must be directly separated and passed through the partition gaps one by one. This is either cumbersome or difficult to operate, resulting in low thermoplastic elastomer manufacturing efficiency.

[0005] Therefore, the present application provides a thermoplastic elastomer rapid cooling device to solve the above problems. Utility Model Content

[0006] The present application provides a thermoplastic elastomer rapid cooling device, which aims to solve the problem of low overall production efficiency caused by cumbersome operation of separation components in the existing thermoplastic elastomer rapid cooling device mentioned in the background art.

[0007] To achieve the above objectives, the present application provides the following technical solution: a rapid cooling device for a thermoplastic elastomer, comprising a cooling water trough and a separation mechanism arranged above the cooling water trough.

[0008] A support frame for supporting the cooling water trough is fixedly installed at the bottom of the cooling water trough.

[0009] The separation mechanism includes a rotating shaft rotatably mounted above the cooling water tank and capable of longitudinal movement; six support rods symmetrically fixed at each end of the shaft and arranged in a circular array; three separation rollers rotatably connected between the symmetrical support rods; a motor rotatably connected to two lifting seats at each end of the shaft, a motor fixedly connected to one of the lifting seats with its output end connected to the rotating shaft; and an electric telescopic rod fixedly mounted on the support frame with its movable end connected to the lifting seat. The separation rollers are provided with axially equidistant separation grooves. This automatic separation mechanism eliminates the need for manual operation; the operator only needs to activate the motor and adjust the height of the electric telescopic rod to complete the entire cooling process. The separation grooves on the separation rollers effectively separate the thermoplastic elastomers, ensuring that each thermoplastic elastomer is adequately cooled. The rotating separation rollers also help stir the cooling water, improving cooling efficiency.

[0010] Preferably, a clearance groove is provided at the feeding end of the cooling water trough, and a receiving roller for receiving the thermoplastic elastic strip is rotatably installed in the clearance groove.

[0011] Preferably, a guide ramp is provided in the discharge end of the cooling water trough for guiding the thermoplastic elastic strip to flow out of the cooling water trough.

[0012] Preferably, the separation mechanism is provided in at least two groups according to the length of the cooling water tank.

[0013] Preferably, the length of the support rod is smaller than the depth of the cooling water tank.

[0014] Preferably, a moving mechanism is provided at the bottom of the support frame, and the moving mechanism includes a plurality of moving wheels fixedly installed on the bottom of the support frame and distributed in a rectangular array, telescopic feet that move longitudinally at the four corners of the support frame, and adjusting nuts that are rotatably connected to the four corners of the support frame and screwed to the telescopic feet.

[0015] Preferably, a circulating heat dissipation mechanism for cooling water circulation and heat dissipation is provided under the cooling water trough, and the circulating heat dissipation mechanism includes a circulating pump fixedly mounted on the support frame, a suction pipe fixedly mounted on the support frame and having its two ends respectively connected to the inlet end of the circulating pump and the feed end of the cooling water trough, and a reflux pipe fixedly mounted on the support frame and having its two ends respectively connected to the outlet end of the circulating pump and the discharge end of the cooling water trough.

[0016] Preferably, a plurality of heat dissipation fins are distributed in a linear array along the axial direction on the outer wall of the water pumping pipe.

[0017] This thermoplastic elastomer rapid cooling device avoids the tedious process of manual operation through a separation mechanism that can automatically separate the thermoplastic elastomer strips. The operator only needs to start the motor and adjust the height of the electric telescopic rod to complete the entire cooling process. The isolation groove on the separation roller can effectively separate the thermoplastic elastomers, ensuring that each thermoplastic elastomer is fully cooled. The rotating separation roller also helps to stir the cooling water, improving cooling efficiency.

[0018] The thermoplastic elastomer rapid cooling device is equipped with a moving mechanism, so when docking with different thermoplastic machine discharge ends, the position can be quickly adjusted and fixed, thereby improving production efficiency and flexibility.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Example 1

[0031] This embodiment provides a thermoplastic elastomer rapid cooling device, such as Figure 1-Figure 4 As shown, the thermoplastic elastomer rapid cooling device includes a cooling water tank 1 and a separation mechanism 3 arranged above the cooling water tank 1.

[0032] A support frame 2 for supporting the cooling water tank 1 is fixedly installed at the bottom of the cooling water tank 1 .

[0033] The separation mechanism 3 includes a rotating shaft 31 that is rotatably arranged above the cooling water tank 1 and moves longitudinally, six support rods 311 symmetrically fixed at both ends of the rotating shaft 31 and distributed in a circular array, three separation rollers 32 rotatably connected between the symmetrical support rods 311, two lifting seats 34 rotatably connected to both ends of the rotating shaft 31, a motor 33 fixedly connected to one of the lifting seats 34 and with the output end connected to the rotating shaft 31, and an electric telescopic rod 35 fixedly mounted on the support frame 2 and with the movable end connected to the lifting seat 34, wherein the separation roller 32 is provided with isolation grooves 321 equidistantly along the axial direction.

[0034] When in use, in the initial state, the rotating shaft 31 of the separation mechanism 3 is suspended above the cooling water tank 1 through the lifting seat 34 and the electric telescopic rod 35, and is in a higher position. The separation roller 32 is connected to the rotating shaft 31 through the support rod 311 and rotates with the rotating shaft 31; when the thermoplastic elastic strip is produced and enters through the feed end of the cooling water tank 1, until it passes under the separation mechanism 3, the motor 33 is started, and the motor 33 drives the rotating shaft 31 and the support rod 311 to rotate, thereby driving the separation roller 32 to rotate, and the electric telescopic rod 35 is shortened to drive the lifting seat 34 and the rotating shaft 31 to move downward. , so that the separation roller 32 is immersed in the cooling water in the cooling water tank 1, and as the separation roller 32 rotates, it continuously contacts the elastic strips and repel the elastic strips through the isolation groove 321, promoting the bundle separation and avoiding mutual adhesion. At the same time, as the separation roller 32 is stirred in the water flow, the hydrophobic guidance of the isolation groove 321 also helps the automatic separation of the elastic strips; as the thermoplastic elastic strip moves in the cooling water tank 1 until it finally separates from the discharge end, it can be used for subsequent production; the entire cooling process can be continuous, so after docking to the discharge end of the thermoplastic machine, it can continue to operate, which is conducive to improving production capacity.

[0035] Furthermore, a clearance groove 11 is provided at the feed end of the cooling water trough 1, and a receiving roller 111 for receiving the thermoplastic elastic strip is rotatably installed in the clearance groove 11; the receiving roller 111 rotates in the clearance groove 11, and its main function is to receive the thermoplastic elastic strip output from the production line and smoothly guide it into the cooling water trough 1, especially to between the separation rollers 32 of the separation mechanism 3.

[0036] Among them, the discharge end of the cooling water trough 1 has a guide ramp 12 that is inclined to guide the thermoplastic elastic strips to flow out of the cooling water trough 1; when the thermoplastic elastic strips are cooled in the cooling water trough 1, they will flow out of the cooling water trough 1 along the inclined surface of the guide ramp 12, which is convenient for subsequent collection and processing.

[0037] Furthermore, at least two groups of separation mechanisms 3 are provided according to the length of the cooling water trough 1; this means that at different positions of the cooling water trough 1, there are separation rollers 32 working to ensure that the thermoplastic elastic strips can be fully separated and pressed throughout the cooling process.

[0038] It should be noted that the length of the support rod 311 is less than the depth of the cooling water tank 1; this means that when the separation mechanism 3 is fully immersed in the cooling water tank 1, the support rod 311 will not touch the bottom of the tank, thereby avoiding wear or noise caused by friction, and also avoiding the elastic strip from rubbing against the bottom of the tank.

[0039] Furthermore, a circulating heat dissipation mechanism 4 for cooling water circulation and heat dissipation is provided under the cooling water tank 1. The circulating heat dissipation mechanism 4 includes a circulating pump 41 fixedly mounted on the support frame 2, a suction pipe 43 fixedly mounted on the support frame 2 and internally connected at both ends to the inlet end of the circulating pump 41 and the feed end of the cooling water tank 1, and a return pipe 42 fixedly mounted on the support frame 2 and internally connected at both ends to the outlet end of the circulating pump 41 and the discharge end of the cooling water tank 1; the circulating pump 41 drives the cooling water to circulate between the suction pipe 43 and the return pipe 42. When the suction pipe 43 draws cooling water from the feed end of the cooling water tank 1 and when the return pipe 42 returns water, heat will be exchanged with the outside through the pipe wall to ensure the recycling of the cooling water.

[0040] Among them, a number of heat dissipation fins 431 are distributed in a linear array along the axial direction on the outer wall of the water pumping pipe 43; when the cooling water after heat exchange flows through the water pumping pipe 43, due to the action of the heat dissipation fins 431, its heat dissipation efficiency can be improved, ensuring that the cooling water can be circulated and cooled, and maintaining the cooling effect of the cooling water tank 1 under continuous operation.

[0041] Example 2

[0042] Different from Example 1, when docking with different thermoplastic machine discharge ends, the lack of a moving mechanism makes transportation difficult, wasting manpower and time. For this reason, a moving mechanism 5 is provided at the bottom of the support frame 2. The moving mechanism 5 includes a plurality of moving wheels 51 fixedly installed on the bottom of the support frame 2 and distributed in a rectangular array, telescopic feet 52 that move longitudinally at the four corners of the support frame 2, and adjusting nuts 53 that are rotatably connected to the four corners of the support frame 2 and screwed to the telescopic feet 52.

[0043] When the cooling device needs to be moved, the operator can push or pull the device to make it slide easily on the ground with the help of the moving wheels 51; the telescopic feet 52 move longitudinally at the four corners of the support frame 2, and the extension length of the telescopic feet 52 can be accurately adjusted by rotating the adjustment nuts 53. Their main function is to adjust the height of the cooling device and provide support when the device needs to be fixed; when docking with different thermoplastic machine discharge ends, the position can be quickly adjusted and fixed, thereby improving production efficiency and flexibility.

[0044] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
