Description

Technical Field

[0001] This utility model relates to the technical field of rubber strip production equipment, specifically a high-efficiency roller cooling device for rubber strips after molding. Background Technology

[0002] In the production process of rubber strips, the freshly formed rubber strips need to be rapidly cooled and set to ensure their physical properties. Existing cooling devices have the following main drawbacks:

[0003] 1. Insufficient cooling efficiency: Traditional devices mostly use single water cooling or air cooling. When water cooling is used, it only relies on the contact heat exchange of the cooling roller, and the heat dissipation area is limited. When air cooling is used, the airflow organization is chaotic, making it difficult to achieve uniform heat dissipation, resulting in low cooling efficiency of the rubber strip and easy local overheating and deformation.

[0004] 2. Risk of friction damage: The cooling roller usually rotates passively, and there is a speed difference between it and the actively conveyed rubber strip. This can easily cause scratches or heat accumulation on the surface of the rubber strip due to sliding friction, affecting the quality of the finished product.

[0005] 3. Short cooling path: The cooling rollers are mostly arranged in a single row. When the rubber strip passes through in a straight line, the cooling stroke is short, and the conveying speed needs to be reduced to meet the cooling requirements, which restricts production efficiency.

[0006] The above-mentioned defects make it difficult for existing equipment to simultaneously meet the requirements of efficient cooling and rubber strip protection. Utility Model Content

[0007] To overcome the problems of low cooling efficiency, friction damage, and short cooling path of rubber strips in existing technologies, this utility model provides a rubber strip roller cooling device. Through a composite cooling structure of water-cooled and air-cooled components, and a synchronous rotation design of cooling roller and conveying roller, the cooling path is extended in an alternating manner to achieve efficient and uniform cooling, completely eliminate friction damage of rubber strips, and significantly extend the cooling stroke to simultaneously improve conveying speed and cooling quality.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: a rubber strip roller cooling device, including a frame for supporting the entire device off the ground; a roller conveyor belt arranged on the upper part of the frame, composed of multiple rollers; the rollers are connected to the frame through bearing seats, and the rollers are driven by gear meshing; one of the rollers is connected to a motor through a chain to provide power; a water cooling assembly arranged on the upper part of the frame and along the rubber strip conveying direction; including a frame, cooling rollers and pressure rollers; the cooling rollers are hollow rollers, with both ends connected to the frame through bearing seats, and one end is provided with a rotary joint to connect to circulating cooling water; the pressure rollers are symmetrically arranged at both ends of the frame to apply downward pressure to the rubber strip; an air cooling assembly arranged on the upper part of the frame and along the rubber strip conveying direction; including a plate frame and multiple fans, the fans being installed on the plate frame; wherein, the cooling rollers and the rollers of the roller conveyor belt are connected by a belt or chain to achieve synchronous rotation.

[0009] In the aforementioned rubber strip roller cooling device, the cooling rollers are arranged in two staggered rows to extend the cooling stroke of the rubber strip.

[0010] In the aforementioned rubber strip roller cooling device, the frame is welded from square tubing, and a plate seat is provided on its upper part; bolts are installed through both ends of the plate seat for fine-tuning the position of the bearing seat of the cooling roller to correct the parallelism.

[0011] The aforementioned rubber strip roller cooling device has an H232L type rotary joint, and an external water pump and water tank form a circulating water circuit.

[0012] In the aforementioned rubber strip roller cooling device, the pressure roller is used to keep the rubber strip tightly against the roller conveyor belt to prevent conveying deviation.

[0013] In the aforementioned rubber strip roller cooling device, the fan is an axial flow fan, and its air outlet direction is arranged along the axial direction of the cooling roller.

[0014] In the aforementioned rubber strip roller cooling device, the plate frame is welded from square tubes and thin plates.

[0015] In the aforementioned rubber strip roller cooling device, the water-cooling component and the air-cooling component are arranged sequentially along the rubber strip conveying direction to achieve composite cooling.

[0016] In the aforementioned rubber strip roller cooling device, the internal circulating cooling water of the cooling roller removes heat from the rubber strip through heat exchange.

[0017] The beneficial effects of this utility model are:

[0018] 1. By having the water-cooling and air-cooling components work together along the conveying direction, a composite heat dissipation of contact water cooling and non-contact air cooling is achieved, thereby significantly improving cooling efficiency and avoiding local overheating and deformation.

[0019] 2. The cooling roller is connected to the drive roller of the roller conveyor belt via a belt / chain to achieve synchronous rotation, thereby eliminating relative slippage between the cooling roller and the rubber strip and effectively avoiding surface scratches and heat accumulation.

[0020] 3. The upper and lower rows of cooling rollers are arranged in an alternating manner to form an S-shaped cooling channel, thereby greatly extending the cooling stroke.

[0021] 4. Fine-tune the parallelism of the cooling rollers with the plate seat bolts, and apply stable downward pressure with the pressure rollers to ensure that the rubber strips are conveyed without deviation. Attached Figure Description

[0028] This embodiment details the specific structure and operation of a rubber strip roller cooling device, such as... Figure 1-4 As shown, the cooling device consists of a frame 1, a roller conveyor belt 2, a water-cooling component 3, and an air-cooling component 4. The frame 1 serves as a ground-supporting element, providing a stable structural foundation for the entire device. The roller conveyor belt 2 is arranged on the upper part of the frame 1 along the conveying direction of the rubber strip. The roller conveyor belt 2 consists of multiple rollers, each of which is connected to the frame 1 via a bearing seat to ensure that the roller can rotate flexibly. The rollers are connected by gear meshing for transmission. This transmission method can ensure the stability and synchronization of the transmission between the rollers. One of the rollers is connected to a motor via a chain. The motor serves as a power source, providing power for the operation of the entire roller conveyor belt 2, driving the roller to rotate, and thus moving the rubber strip along the conveying direction. In order to achieve rapid cooling after the rubber strip is produced, the water-cooling component 3 and the air-cooling component 4 are respectively arranged on the upper part of the frame 1 along the conveying direction of the rubber strip.

[0029] The water-cooled assembly 3 includes a frame 31, pressure rollers 32, cooling rollers 33, a rotary joint 34, and a plate base 35. The frame 31 is located above the machine frame 1 and is constructed by welding together square tubing. This structure ensures the strength and stability of the frame 31. Cooling rollers 33 are arranged at intervals along the conveying direction of the rubber strip on the upper part of the frame 31. The cooling rollers 33 are divided into upper and lower rows. Each end of the cooling roller 33 is provided with a bearing seat connected to the frame 31. To improve the parallelism between the cooling rollers 33, additional bearing seats are added at the bearing seat locations on the upper part of the frame 31. The plate base 35 is connected to the frame 31. Bolts that abut against the bearing seats are arranged through both ends of the plate base 35. By rotating the bolts, the position of the bearing seats inside the plate base 35 can be finely adjusted, thereby correcting and adjusting the parallelism of the cooling rollers 33. This ensures that the spacing between the cooling rollers 33 is uniform, allowing the rubber strip to pass through smoothly. During the conveying process, the rubber strip passes through the vertically staggered cooling rollers 33, which can extend the cooling stroke of the rubber strip and improve the cooling effect. The cooling rollers 33 are hollow rollers, with H232 arranged at one end. The L-shaped rotary joint 34 allows access to circulating cooling water. An external water pump and water tank are connected to the rotary joint 34. The water pump draws cooling water from the tank and delivers it to the cooling roller 33. The cooling water circulates within the cooling roller 33, carrying away heat transferred from the rubber strip to the roller wall, thus achieving water-cooling of the rubber strip. The connection between the water pump and water tank and the rotary joint 34, as well as the configuration of the circulating water path, are standard practices in the art and will not be elaborated further here. To ensure stable delivery of the rubber strip, the frame 3... Pressure rollers 32 are symmetrically arranged at both ends of 1. The pressure rollers 32 apply stable downward pressure to the rubber strip, so that the rubber strip can be pulled by the roller conveyor belt 2 below the pressure rollers 32, preventing the rubber strip from deviating or jumping during the conveying process. At the same time, in order to reduce the friction loss between the cooling roller 33 and the rubber strip, the end of the cooling roller 33 without the rotating joint 34 is connected to the adjacent roller of the roller conveyor belt 2 through a belt or chain, so that the cooling roller 33 can rotate synchronously with the roller of the roller conveyor belt 2, reducing the relative sliding friction between the two.

[0030] The air-cooled assembly 4 includes a plate frame 41 and a fan 42. The plate frame 41 is arranged on one side of the frame 1 and is made of square tubes and thin plates welded together. This structure provides a stable installation platform for the fan 42. Multiple fans 42 are arranged at intervals on the upper part of the plate frame 41 along the conveying direction of the rubber strip. The fan 42 is an axial flow fan. When the rubber strip is initially cooled by the water-cooled assembly 3, it is also in the area of ​​the air-cooled assembly 4. The axial flow fan 42 can blow air to cool the rubber strip along the axial direction of the cooling roller 33, further accelerating the air flow speed on the surface of the rubber strip, removing the heat from the surface of the rubber strip, and achieving secondary cooling. The power connection operation of the fan 42 is a conventional method in this field and will not be described in detail here.

[0031] In actual operation, the motor starts and drives the rollers of the roller conveyor belt 2 to rotate via the chain, which in turn drives the rubber strip to move along the conveying direction. The rubber strip first enters the water-cooling component 3 area and passes through the cooling rollers 33 arranged vertically. The circulating cooling water in the cooling rollers 33 exchanges heat with the rubber strip to achieve water-cooling heat dissipation. At the same time, the pressure rollers 32 apply downward pressure to the rubber strip to ensure stable conveying of the rubber strip. The cooling rollers 33 rotate synchronously with the rollers of the roller conveyor belt 2. During the water-cooling process, the rubber strip is also in the air-cooling component 4 area, where the axial flow fan 42 blows air to dissipate heat from the rubber strip, completing the composite cooling process. When cooling each roll of rubber strip, it is necessary to manually pull the rubber strip through the cooling rollers 33 before the automatic traction cooling operation can be performed.
