Description

Technical Field

[0001] This utility model relates to the field of elastomer production technology, specifically to a high-efficiency cooling device for elastomer production. Background Technology

[0002] Thermoplastic elastomers, also known as synthetic rubber or artificial rubber, possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as ease of processing and a wide range of processing methods.

[0003] Existing elastomers typically require granulation during production and processing. After granulation through the first few processes, the temperature remains high and needs to be cooled and dissipated. Existing equipment usually uses air cooling or spraying cold water to cool them down. However, air cooling has limited cooling capacity and low efficiency, while direct contact with cold water makes it easy for moisture to remain inside, requiring further drying, which increases costs and time.

[0004] Therefore, we propose a high-efficiency cooling device for elastomer production to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-efficiency cooling device for elastomer production, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A high-efficiency cooling device for elastomer production includes: a base, an outer roller mounted on top of the base, an inner roller installed inside the outer roller, and a metal heat sink installed inside the inner roller. It also includes: four sets of protrusions are fixed on the inner wall of the outer roller, each of which has a track. A slider with the same size as the track on the inner wall of the outer roller is fixed on the outer side of the inner roller, allowing the inner roller to move along the direction of the track on the inner side of the outer roller. A set of racks and a set of annular grooves are fixed on the outer side of the outer roller. The racks fixed on the outer roller can mesh with the teeth on the two sets of gears below the outer roller. A set of tracks is also opened in the annular grooves fixed on the outer roller. The dimensions of the tracks can also match the two sets of rollers below, allowing the rollers to move on the tracks.

[0007] Furthermore, a set of motors is installed on one side above the base, and each motor has a gear installed on its drive end. The gears are connected to the outer roller through a rack and pinion for transmission.

[0008] Furthermore, two sets of fixing brackets are installed on the side of the motor above the base. Circular holes are opened on both sides of the fixing brackets. The rollers are rotatably connected to the fixing brackets above the base by rotating shafts set inside the rollers.

[0009] Furthermore, a set of cooling water pipes is installed between the inner roller and the metal heat sink, with an inlet and an outlet on each side of the cooling water pipes.

[0010] Furthermore, the two sides of the heat dissipation water pipe are connected by a set of connecting water pipes, and two corresponding sets of channels are opened inside the two sides of the connecting water pipes.

[0011] Furthermore, a set of water storage tanks is installed on the base away from the outer roller, and a water pump is installed on the top of the water storage tanks. A set of pipes is connected to the drive end of the water pump.

[0012] Furthermore, a set of rotary joints is installed on the middle part of the connecting water pipe. The rotating end of the rotary joint is connected to the connecting water pipe, and the fixed end on the other side of the rotary joint is connected to the pipe on the water pump drive end.

[0013] Beneficial effects Compared with the prior art, this utility model provides a high-efficiency cooling device for elastomer production, which has the following beneficial effects: This invention utilizes two sets of gears and rollers mounted above the base to support the outer roller while simultaneously driving it to rotate using a drive motor. An inner roller installed inside the outer roller rotates in tandem with it. The metal surface of the heat sink absorbs heat, cooling the elastomeric particles that enter from the outside. A water pipe connected to the inner roller and the heat sink, along with a conveying device, circulates water stored in an external water tank via a pump, effectively transferring the heat absorbed by the heat sink. The rotating outer roller increases the contact area between the heat sink and the particles, making heat dissipation more efficient and effectively overcoming the shortcomings of traditional heat dissipation methods. Furthermore, the detachable design of both the inner roller and the heat sink allows for easy removal, cleaning, and replacement, enhancing practicality. Attached Figure Description

[0016] 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.

[0017] Example like Figure 1-3As shown in the figure, an embodiment of this utility model discloses a high-efficiency cooling device for elastomer production, comprising: a base 1, an outer roller 2 mounted on the top of the base 1, an inner roller 3 installed inside the outer roller 2, and a metal heat sink 4 installed inside the inner roller 3; further comprising: four sets of protrusions fixed on the inner wall of the outer roller 2, each protrusion having a track; and a slider of the same size as the track on the inner wall of the outer roller 2 fixed on the outer side of the inner roller 3, allowing the inner roller 3 to move along the direction of the track on the inner wall of the outer roller 2. When the internal track is limited, the inner side of the protrusion on the outer roller 2 and the outer side of the slider on the inner roller 3 are provided with threaded holes and slots of the same size. Multiple sets of positioning bolts are connected through the slots and threaded holes, so that the inner roller 3 can be fixedly installed inside the outer roller 2. The slider fixed on the inner roller 3 is also provided with a groove. A fixing seat 13 is installed inside the groove. The fixing seat 13 is provided with threaded holes. The same fixing seat 13 is installed at the same position on both sides of the metal heat sink 4. The metal heat sink 4 can be fixedly installed inside the inner roller 3 by positioning bolts. A set of racks and a set of annular grooves are fixed on the outer side of the outer roller 2. Two sets of support seats are fixed on the top of the base 1. A set of motors 5 is installed on one side of one set of support seats, and a set of brackets is installed on the other side. The drive end of the motor 5 and the bracket are equipped with two sets of gears 14. The teeth of the rack on the outer roller 2 can mesh with the two sets of gears 14 at the same time. Two sets of brackets are also installed on the other set of support seats fixed on the top of the base 1. Rollers 6 are installed on both sets of brackets. The rollers 6 have a rotating shaft inside. The brackets have round holes on both sides that allow the rotating shaft to be installed and rotate inside. The rollers 6 are installed inside the brackets through the round holes. According to the design, the two sets of rollers 6 are matched with the track size opened in the annular groove on the outer roller 2, so that the two sets of rollers 6 can support one side of the outer roller 2 and rotate with the outer roller 2. A set of water storage tanks 10 is provided on the top of the base 1, away from the outer roller 2. The top of the water storage tanks 10 has a water outlet. A set of water pumps 7 is installed on the top of the water storage tanks 10. The drive end of the water pumps 7 is connected to a set of pipes. The pipes connected to the water pumps 7 are connected to the water outlet pipes on the water storage tanks 10, so that cold water can be drawn from the inside of the water storage tanks 10 when the water pumps 7 are driven.A set of cooling water pipes 12 is installed between the inner roller 3 and the metal heat dissipation cylinder 4. The cooling water pipes 12 have inlets and outlets on both sides respectively. The two sides of the cooling water pipes 12 are connected by a set of connecting water pipes 8. The two sides of the connecting water pipes 8 have two corresponding channels, which are not connected to each other. The rotary joint 9 has two different channels inside. The rotating end of the rotary joint 9 is installed on the connecting water pipe 8. The channel inside the rotary joint 9 is also connected to the channel inside the connecting water pipe 8. The water inlet hole inside the fixed end of one side of the rotary joint 9 is connected to the pipe on the water pump 7, and the other outlet is connected to the external pipe to deliver hot water. It can also be used for other processes.

[0018] During processing, an external conveying device feeds the elastomer particles from one side of the outer roller 2. The heated particles then come into contact with the metal heat sink 4 installed inside the outer roller 2 for heat exchange. Simultaneously, the drive motor 5 drives the gear 14 to mesh with the rack on the outer side of the outer roller 2, causing the outer roller 2 to rotate. During rotation, the particles continuously come into contact with the surface of the metal heat sink 4, increasing the heat exchange area and making the cooling speed faster and more efficient. While rotating, the rotary joint 9 can transport liquids during rotation. The water pump 7 draws cold water from the water storage tank 10 and flows through the inlet on the side of the rotary joint 9 and the connecting water pipe 8, finally flowing into the heat dissipation water pipe 12. This ensures that the inside of the metal heat sink 4 always maintains a low temperature. The hot water inside the heat dissipation water pipe 12, which has undergone heat exchange, is discharged from the outlet on the connecting water pipe 8 and the rotary joint 9 using an external conveying device. This enables resource recycling and avoids waste. The cooled particles can be poured out from the discharge port 11 on one side of the base 1 due to the slope design of the base 1 surface. When internal replacement and cleaning are required, simply remove the positioning bolts that secure the outer roller 2 and inner roller 3, and remove the inner roller 3 along with the internal structure. If only the metal heat sink 4 needs to be removed, simply remove the positioning bolts installed on the mounting base 13. The structure is simple and easy to operate, while also effectively addressing the shortcomings of traditional heat dissipation devices and improving production efficiency.
