Description

Technical Field

[0001] The utility model relates to the technical field of mixer rubber production, in particular to a cooling device for mixer rubber production. Background Technique

[0002] The main raw materials of mixer rubber are methyl or vinyl raw rubber, and are mixed at high temperature after adding various materials such as silica and cross-linking agent. Then, the high-temperature mixer rubber is cooled by a cooling device to complete the production.

[0003] The existing cooling device for mixer rubber production cools the mixer rubber through a conveyor belt or conveyor roller by passing it through cooling equipment such as a fan.

[0004] The existing cooling device for mixer rubber production is prone to causing the mixer rubber to shift and stack during the cooling process. And during the cooling process, the motor is stopped and started to enable the mixer rubber to obtain a longer cooling time in the cooling equipment, which will increase the burden on the motor and reduce the service life of the motor. For this reason, we propose a cooling device for mixer rubber production. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a cooling device for mixer rubber production, which can adapt to mixer rubber of different widths and limit it to prevent the mixer rubber from shifting and stacking. At the same time, the intermittent transmission mechanism enables the motor to run continuously while ensuring that the mixer rubber has sufficient cooling time for cooling, prolonging the service life of the motor, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A cooling device for mixer rubber production, including a housing and an intermittent transmission mechanism;

[0007] Housing: The left side inside it is rotatably connected with a second rotating roller through a bearing, and an aggregate roller is fixedly connected to the surface of the second rotating roller through bolts;

[0008] Intermittent transmission mechanism: including a transmission shaft, a gear and an eighth bevel gear. The transmission shaft is rotatably connected to the left side inside the housing. The middle part of the outer surface of the transmission shaft is fixedly connected with a gear. The left side bottom wall inside the housing is rotatably connected with a connecting shaft, and an eighth bevel gear is fixedly connected to the upper end of the connecting shaft. The gear and the eighth bevel gear are cooperatively installed;

[0009] Wherein: the inside of the housing is rotatably connected with evenly distributed first rotating rollers, and the inside of the housing is rotatably connected with symmetrically distributed pressing rollers. The left pressing roller is located above the leftmost first rotating roller, and the right pressing roller is located directly above the rightmost first rotating roller, which can adapt to mixing rubbers of different widths and limit them to prevent the mixing rubber from shifting and overlapping. At the same time, the intermittent transmission mechanism enables the motor to continuously operate while ensuring that the mixing rubber has sufficient cooling time for cooling.

[0010] Further, a motor is fixedly connected to the left side of the lower surface inside the housing. The output shaft of the motor is fixedly connected to the lower end of the connecting shaft, and the input end of the motor is electrically connected to the output end of an external control switch group to provide driving force.

[0011] Further, a driving wheel is fixedly connected to the front end of the outer surface of the transmission shaft, and a driven wheel is fixedly connected to the front end of the second rotating roller. The driving wheel and the driven wheel are connected by belt transmission to transmit power.

[0012] Further, symmetrically distributed threaded rods are rotatably connected to the upper end inside the housing. Knobs are fixedly connected to the front ends of the threaded rods. The front and rear ends of the outer surfaces of the threaded rods are both threadedly connected with sliders. The upper surfaces of the sliders are both slidably connected to the upper surface inside the housing, and guide rollers are fixedly connected to the lower ends of the sliders to limit the mixing rubber.

[0013] Further, a trailing roller is rotatably connected to the right end of the housing to guide the movement trajectory of the mixing rubber.

[0014] Further, supporting feet are fixedly connected to the lower surface of the housing to support the cooling equipment.

[0015] Further, ventilation openings are provided on both the front and rear surfaces of the housing to ensure air circulation and improve the cooling efficiency.

[0016] Further, evenly distributed fans are fixedly connected to both the upper and lower surfaces inside the housing. The input ends of the fans are electrically connected to the output end of an external control switch group to cool the mixing rubber.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This cooling device for the production of mixing rubber has the following advantages:

[0018] 1. Rotate the knob to rotate the threaded rod, so that the slider drives the guide roller to move. The threads at the front and rear ends of the threaded rod are opposite, and the distance between the guide rollers is adjusted to an appropriate width to limit the mixing rubber, which can adapt to mixing rubbers of different widths and limit them to prevent the mixing rubber from shifting and overlapping.

[0019] 2. Operate the external control switch group. The motor runs, and the output shaft of the motor rotates, driving the connecting shaft to rotate, thereby causing the one-eighth bevel gear to rotate. When the teeth of the one-eighth bevel gear rotate to mesh with the gear, the gear is driven to rotate. When the teeth of the one-eighth bevel gear separate from the teeth of the gear, the gear stops rotating. In this way, the periodic rotation of the gear is realized repeatedly, driving the drive shaft to rotate periodically, causing the driving wheel to rotate periodically, driving the driven wheel to rotate periodically, and causing the aggregate roller to rotate periodically. The intermittent transmission mechanism enables the motor to continue running while ensuring that the mixed rubber has sufficient cooling time for cooling, extending the service life of the motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , this embodiment provides a technical solution: A cooling device for the production of mixed rubber includes a housing 1 and an intermittent transmission mechanism 7;

[0028] Shell 1: A second rotating roller 14 is rotatably connected to the left side inside it through a bearing. An aggregate roller 8 is fixedly connected to the surface of the second rotating roller 14 by bolts. Symmetrically distributed threaded rods 9 are rotatably connected to the upper end inside the shell 1. Knobs 3 are fixedly connected to the front ends of the threaded rods 9. The front and rear ends of the outer surface of the threaded rod 9 are both threadedly connected with sliders 17. The upper surfaces of the sliders 17 are both slidably connected to the upper surface inside the shell 1. Guide rollers 5 are fixedly connected to the lower ends of the sliders 17. Rotate the knob 3 to rotate the threaded rod 9, so that the slider 17 drives the guide roller 5 to move. The threads at the front and rear ends of the threaded rod 9 are opposite, so that the distance between the guide rollers 5 is adjusted to an appropriate width to limit the mixing rubber. A trailing roller 6 is rotatably connected to the right end of the shell 1. Support feet 2 are fixedly connected to the lower surface of the shell 1. Ventilation openings 4 are provided on the front and rear surfaces of the shell 1. Uniformly distributed fans 13 are fixedly connected to the upper and lower surfaces inside the shell 1. The input end of the fan 13 is electrically connected to the output end of an external control switch group. When the fan 13 operates, it blows air on the mixing rubber to cool it down;

[0029] Intermittent transmission mechanism 7: It includes a transmission shaft 71, a gear 72 and an eighth bevel gear 73. The transmission shaft 71 is rotatably connected to the left side inside the shell 1. A driving wheel 15 is fixedly connected to the front end of the outer surface of the transmission shaft 71. A driven wheel 16 is fixedly connected to the front end of the second rotating roller 14. The driving wheel 15 and the driven wheel 16 are connected by a belt drive. A gear 72 is fixedly connected to the middle of the outer surface of the transmission shaft 71. A connecting shaft is rotatably connected to the bottom wall on the left side inside the shell 1. An eighth bevel gear 74 is fixedly connected to the upper end of the connecting shaft. The gear 72 is installed in cooperation with the eighth bevel gear 74. A motor 12 is fixedly connected to the lower surface on the left side inside the shell 1. The output shaft of the motor 12 is fixedly connected to the lower end of the connecting shaft. The input end of the motor 12 is electrically connected to the output end of an external control switch group. When the motor 12 operates, the output shaft of the motor 12 rotates, driving the connecting shaft to rotate, so that the eighth bevel gear 73 rotates. When the teeth of the eighth bevel gear 73 rotate to mesh with the gear 72, it drives the gear 72 to rotate. When the teeth of the eighth bevel gear 73 are separated from the teeth of the gear 72, the gear 72 stops rotating. Repeating this way realizes the periodic rotation of the gear 72, driving the transmission shaft 71 to rotate periodically, making the driving wheel 15 rotate periodically, driving the driven wheel 16 to rotate periodically, and making the aggregate roller 8 rotate periodically;

[0030] Among them: A plurality of first rotating rollers 10 are rotatably connected inside the shell 1 at equal intervals. Symmetrically distributed pressing rollers 11 are rotatably connected inside the shell 1. The left pressing roller 11 is located above the leftmost first rotating roller 10, and the right pressing roller 11 is located directly above the rightmost first rotating roller 10.

[0031] The working principle of a cooling device for the production of mixed rubber provided by the present utility model is as follows: When cooling the mixed rubber, the mixed rubber is passed successively above the drag roller 6, between the longitudinally adjacent guide rollers 5 on the right side, between the first rotating roller 10 and the pressing roller 11 on the right side, between the first rotating roller 10 and the pressing roller 11 on the left side, and between the longitudinally adjacent guide rollers 5 on the left side, and then one end of it is fixed to the collecting roller 8. At this time, turn the knob 3 to rotate the threaded rod 9, so that the slider 17 drives the guide roller 5 to move. The threads at the front and rear ends of the threaded rod 9 are opposite, and the distance between the guide rollers 5 is adjusted to an appropriate width to limit the mixed rubber. At this time, operate the external control switch group to turn on the motor 12 and the fan 13. The fan 13 runs to blow air on the mixed rubber for cooling. The motor 12 runs, and the output shaft of the motor 12 rotates to drive the connecting shaft to rotate, so that the one-eighth bevel gear 73 rotates. When the teeth of the one-eighth bevel gear 73 rotate to mesh with the gear 72, the gear 72 is driven to rotate. When the teeth of the one-eighth bevel gear 73 are separated from the teeth of the gear 72, the gear 72 stops rotating. In this way, the periodic rotation of the gear 72 is realized repeatedly, driving the transmission shaft 71 to rotate periodically, making the driving wheel 15 rotate periodically, driving the driven wheel 16 to rotate periodically, making the collecting roller 8 rotate periodically, and the collecting roller 8 drives the mixed rubber to be periodically pulled and advanced, cooperating with the fan 13 to achieve the cooling operation.

[0032] It should be noted that in the above embodiments, the motor 12 disclosed is an MZ751 N2 servo motor, the fan 13 is a KDE2404PFV cooling fan, and the external control switch group is provided with control buttons corresponding to the motor 12 and the fan 13 one by one and used to control their switches.
