Description

Technical Field

[0001] This utility model relates to the field of rubber mixing machines, specifically a roller temperature regulating mechanism for a rubber mixing machine. Background Technology

[0002] Rubber mixing mills are divided into two types: open and closed. Open rubber mixing mills are usually used for rubber production. The heating rollers are important parts of the rubber mixing mill. Rubber processing involves placing the rubber mixture in the gap between adjacent heated rollers and subjecting it to repeated shearing action. Through friction and heating, the rubber reaches a certain temperature and plastic state.

[0003] A specific example of an existing rubber mixing mill roller temperature regulation mechanism can be found in application number CN202223343489.1. This mechanism includes: a rubber mixing roller and two mounting blocks. A rotating shaft is fixedly installed at both ends of the rubber mixing roller, and the rotating shaft is rotatably mounted on the mounting blocks. A roller temperature regulation component is mounted on the rubber mixing roller. The roller temperature regulation component includes a base, a heat-conducting adapter block, an inlet pipe, and an outlet pipe. A groove is formed at the top of the base, and the heat-conducting adapter block is fixedly installed in the groove. The outer bottom of the rubber mixing roller contacts the heat-conducting adapter block. The inlet pipe and outlet pipe are both fixedly installed on the base. Coolant flows in the groove. Two connecting blocks are fixedly installed at the top of the base, and connecting grooves are formed at the bottom of the mounting blocks. The connecting blocks are engaged with the connecting grooves. This invention has the following advantages and effects: it can uniformly cool the rubber mixing roller.

[0004] The aforementioned rubber mixing mill roller achieves uniform heating or cooling of the rubber mixing mill by introducing liquid into the inside of the rubber mixing mill roller. However, in actual rubber processing, it is not necessary to uniformly heat the entire rubber mixing mill roller during the processing of a small amount of rubber. Only a localized part in the middle of the mixing mill roller needs to be heated. If the entire mixing mill roller is heated in this case, it will result in energy waste. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, rubber mixing mill rollers currently achieve uniform heating or cooling of the rubber mixing mill by introducing liquid into the rollers. However, in actual rubber processing, some small amounts of rubber do not require uniform heating of the entire rubber mixing mill roller; only a localized area in the middle of the roller needs to be heated. If the entire roller is heated in this case, it will result in energy waste. This utility model proposes a rubber mixing mill roller temperature regulation mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The rubber mixing mill roller temperature regulating mechanism of this utility model includes a hot pressing roller, a heating groove is opened inside the hot pressing roller, a moving groove is opened at the top and bottom of the heating groove, a moving mechanism is arranged inside the moving groove, the moving mechanism includes a screw, the screw is rotatably connected to both ends of the moving groove, a moving block is threadedly connected to the outer side of both ends of the screw, hollow columns are arranged at both ends of the heating groove, the outer side of the hollow columns is fixedly connected to two sets of moving blocks, and multiple sets of long rods are arranged inside the heating groove, the two ends of the long rods pass through the two sets of hollow columns and are fixedly connected to the two ends of the heating groove.

[0007] Preferably, a heating wire spring is sleeved on the outside of the long rod, and the two ends of the heating wire spring are fixedly connected to one side of two sets of hollow columns at both ends inside the heating groove.

[0008] Preferably, the movable block is inside the movable slot, and the size of the movable block is adapted to the movable slot.

[0009] Preferably, a limiting post is fixedly connected to the outer side of the middle part of the screw, and the threads at both ends of the screw are opposite.

[0010] Preferably, a mounting groove is provided on one side of the hot press roller, and a transmission mechanism is provided inside the mounting groove. The transmission mechanism includes two sets of rotating columns, and the two sets of rotating columns pass through the hot press roller and are fixedly connected to one end of two sets of screws. A transmission belt is sleeved on the outside of the rotating columns, and the transmission belt meshes with the rotating columns.

[0011] Preferably, a protective shell is provided on the outer side of the transmission belt, and the protective shell is fixedly connected to the mounting groove. A motor is fixedly connected to one end of the protective shell, and the output shaft of the motor passes through the protective shell and is fixedly connected to one of the sets of rotating columns.

[0012] The advantages of this utility model are:

[0013] This invention, through the structural design of the moving mechanism, realizes that based on the structural characteristics of the heating wire spring, when the motor is turned on, it works with the transmission mechanism to drive two sets of screws to rotate, thereby causing the moving block and hollow column to move towards each other. This allows the heating wire spring to be stretched or compressed. The length of the heating wire spring corresponds to the concentrated heating position on the outer side of the hot press roller. When processing small amounts of rubber, the rubber will only roll and be crushed in the middle of the heating roller, without needing to reach both ends. Therefore, only the middle part of the heating roller needs to be heated. This reduces the power required to power the heating wire spring and allows the middle part of the hot press roller to reach the appropriate temperature, thus reducing power consumption. This solves the problem that current rubber mixing mills achieve uniform heating or cooling by introducing liquid into the rubber mixing mill roller. However, in actual rubber processing, some small amounts of rubber do not require uniform heating of the entire rubber mixing mill roller; only the middle part of the mixing mill roller needs to be heated. If the entire mixing mill roller is heated in this case, it will result in energy waste. Attached Figure Description

[0020] 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 scope of protection of the present utility model.

[0021] Please see Figure 1 - Figure 4 As shown, a rubber mixing mill roller temperature regulating mechanism includes a hot press roller 1, a heating groove 2 is provided inside the hot press roller 1, a moving groove 3 is provided at the top and bottom of the heating groove 2, a moving mechanism is provided inside the moving groove 3, the moving mechanism includes a screw 4, the screw 4 is rotatably connected to both ends of the moving groove 3, the outer sides of both ends of the screw 4 are threaded with moving blocks 5, hollow columns 6 are provided at both ends inside the heating groove 2, the outer sides of the hollow columns 6 are fixedly connected to two sets of moving blocks 5, and multiple sets of long rods 7 are provided inside the heating groove 2, the two ends of the long rods 7 pass through the two sets of hollow columns 6 and are fixedly connected to both ends inside the heating groove 2.

[0022] During operation, the motor 14 is activated in conjunction with the transmission mechanism to rotate the two sets of screws 4, thereby driving the corresponding movement of the two sets of hollow columns 6 inside the heating tank 2. This allows for adjustment of the length of the heating wire spring 8, thus achieving localized heating of the hot press roller 1. The long rod 7 ensures the position of the heating wire spring 8 and prevents the spring position from shifting when the two sets of hollow columns 6 move towards each other.

[0023] Furthermore, such as Figure 4 As shown, a heating wire spring 8 is sleeved on the outside of the long rod 7, and the two ends of the heating wire spring 8 are fixedly connected to one side of the two sets of hollow columns 6 at both ends inside the heating tank 2.

[0024] During operation, the heating wire spring 8 is heated by an electric current, thereby heating the hot press roller 1. According to the structural characteristics of the heating wire spring 8, when the hollow column 6 moves towards each other, the heating wire spring 8 can be stretched or compressed. The length of the heating wire spring 8 is the location where the outer side of the hot press roller 1 is concentratedly heated. When processing a small amount of rubber, the rubber will only roll and be pressed in the middle of the heated roller, without needing to reach both ends of the heated roller. Therefore, only the middle part of the heated roller needs to be heated. This can reduce the power required to power the heating wire spring 8 and achieve the desired temperature in the middle part of the hot press roller 1, thereby reducing power consumption.

[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the movable block 5 is inside the movable slot 3, and the size of the movable block 5 is adapted to the movable slot 3;

[0026] During operation, the rotation of screw 4 will cause the moving block 5 to have the same rotation tendency. Since the size of the moving block 5 is adapted to the moving groove 3, the rotation tendency of the moving block 5 will be hindered by the moving groove 3. Furthermore, due to the threaded connection between the moving block 5 and screw 4, the moving block 5 can move on screw 4 as screw 4 rotates.

[0027] Furthermore, such as Figure 3 and Figure 4 As shown, a limit post 9 is fixedly connected to the outer side of the middle part of the screw 4, and the threads at both ends of the screw 4 are opposite.

[0028] During operation, the threads on both sides of the screw 4 about the limiting post 9 are opposite, so when the screw 4 rotates, the two sets of moving blocks 5 inside the same moving groove 3 will move towards each other, thus making them move towards each other. The limiting post 9 can prevent the two sets of moving blocks 5 from colliding with each other. At the same time, the two sets of moving blocks 5 can only move to both sides of the limiting post 9. The minimum position that the heating roller can heat is the length of the limiting post 9.

[0029] Furthermore, such as Figure 2 As shown, a mounting groove 10 is provided on one side of the hot press roller 1. A transmission mechanism is provided inside the mounting groove 10. The transmission mechanism includes two sets of rotating columns 11. The two sets of rotating columns 11 pass through the hot press roller 1 and are fixedly connected to one end of the two sets of screws 4. A transmission belt 12 is sleeved on the outside of the rotating columns 11. The transmission belt 12 meshes with the rotating columns 11.

[0030] During operation, the stable movement of the hollow column 6 requires the simultaneous movement of the two sets of moving blocks 5 connected to it. That is, the two sets of screws 4 need to rotate simultaneously in the same direction and at the same speed. Originally, two sets of motors 14 were needed to control the rotation of the two sets of screws 4 respectively. In order to prevent errors and to avoid the high production cost of setting multiple sets of motors 14, two sets of rotating columns 11 are fixedly connected to the two sets of screws 4, and the same transmission belt 12 is used to be sleeved on the outside of the two sets of rotating columns 11. In this way, only one set of first motors 14 is needed to control the rotation of the two sets of rotating columns 11 and screws 4 at the same time. The transmission belt 12 meshes with the rotating column 11 to prevent the transmission belt 12 from slipping on the rotating column 11.

[0031] Furthermore, such as Figure 2 As shown, a protective shell 13 is provided on the outside of the transmission belt 12, and the protective shell 13 is fixedly connected to the mounting groove 10. The protective shell 13 is fixedly connected to the mounting groove 10, and a motor 14 is fixedly connected to one end of the protective shell 13. The output shaft of the motor 14 passes through the protective shell 13 and is fixedly connected to one of the sets of rotating columns 11.

[0032] During operation, the protective shell 13 can prevent the transmission belt 12 from falling off the rotating column 11, and at the same time protect external personnel from touching the rotating transmission belt 12 and the rotating column 11.

[0033] The working principle is as follows: When a small amount of rubber needs to be processed, the maximum length limit of the rubber rolling on the heating roller is first determined. Then, the motor 14 is turned on to drive the rotating column 11 connected to it to rotate, which in turn drives the transmission belt 12 and another set of rotating columns 11 to rotate, that is, the two sets of screws 4 rotate. As the screws 4 rotate, the movement of the two ends of the screws 4 will drive the two sets of hollow columns 6 to move towards each other along the long rod 7 inside the heating groove 2. At this time, the heating wire spring 8 will be compressed. When the length of the heating wire spring 8 is compressed to the maximum length limit of the rubber rolling on the heating roller, the motor 14 is stopped. At this time, the operation of the heating wire spring 8 is turned on, that is, current is passed to achieve heating, so that the position of the outer side of the hot pressure roller 1 in close contact with the heating wire spring 8 meets the rubber heating requirements.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
