Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for internal mixers, specifically a rubber discharge temperature measuring device. Background Technology

[0002] Rubber compounds are unvulcanized (or partially vulcanized) mixtures formed by mixing rubber with various compounding agents. They are the core semi-finished raw materials for rubber products.

[0003] Currently, the temperature measurement of rubber compound discharge in the mixing workshop is still mainly done manually after discharge. This requires categorizing by rubber grade or sampling every 10 batches produced, resulting in 10-20 measurements per shift. Operators must repeatedly insert a needle thermometer into the high-temperature rubber compound to take multiple readings and average them under the high-temperature environment at the discharge port. This is not only labor-intensive and time-consuming but also poses safety hazards such as burns. This sampling method cannot achieve full coverage testing of each batch of rubber compound, and some abnormal temperature rubber compounds are easily missed, which may lead to problems such as uneven vulcanization, scorching, or poor dispersion of compounding agents. At the same time, the manually recorded temperature data is scattered and incomplete, making it difficult to form a continuous and traceable production data chain. This results in a lack of accurate basis for quality control and an inability to trace the root cause of abnormal batches in a timely manner, which seriously restricts the stability of rubber compound quality and the improvement of production efficiency. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a rubber discharge temperature measuring device, which has the advantages of automatically measuring the discharge temperature and saving labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber compound discharge temperature measuring device, comprising a material preparation hopper, mounting frames fixedly connected to the left and right sides of the bottom of the material preparation hopper, a mounting frame movably connected to the inner side of the mounting frame, a controller fixedly installed inside the mounting frame, a buzzer fixedly connected to the outer side of the mounting frame, and four thermocouples fixedly installed inside the bottom of the material preparation hopper. Each of the four thermocouples has a wire fixedly connected to its bottom, and the other end of the wire is electrically connected to the input terminal of the controller.

[0006] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the bottom of the mounting frame, a threaded rod is movably sleeved on the outer surface of the fixing block, a rectangular plate is movably sleeved on the outer surface of one end of the threaded rod, and the top of the rectangular plate is fixedly connected to the bottom of the mounting frame.

[0007] As a preferred embodiment of this utility model, a movable plate is threaded onto the outer surface of the threaded rod. The top of the movable plate is movably connected to the bottom of the mounting frame. A connecting rod is hinged to the outer side of the movable plate, and an L-shaped plate is hinged to the other end of the connecting rod. There are two L-shaped plates. The inner sides of the two L-shaped plates are movably connected to the outer sides of two mounting brackets respectively. A pin is fixedly connected to the inner side of each of the two L-shaped plates. The inner side of the pin passes through the mounting bracket and the mounting frame in sequence and extends into the interior of the mounting frame.

[0008] As a preferred embodiment of this utility model, the bottom of the mounting frame is provided with a sliding groove, and a limiting block is movably connected inside the sliding groove. The bottom of the limiting block is fixedly connected to the outer surface of the L-shaped plate.

[0009] As a preferred embodiment of this utility model, the number of the limiting blocks is two, and both limiting blocks are T-shaped.

[0011] As a preferred embodiment of this utility model, the number of dampers is two, the two dampers are of the same size, and the two dampers are symmetrical about the center of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a controller, buzzer, thermocouples and wires, allows the rubber material to enter the preparation hopper. Under the action of gravity, the four thermocouples on the bottom of the preparation hopper are inserted into the rubber material to measure the temperature.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a rubber discharge temperature measuring device, including a material preparation hopper 1. Mounting brackets 2 are fixedly connected to the left and right sides of the bottom of the material preparation hopper 1. Mounting frames 3 are movably connected to the inner side of the mounting brackets 2. A controller 4 is fixedly installed inside the mounting frames 3. A buzzer 5 is fixedly connected to the outer side of the mounting brackets 2. Four thermocouples 6 are fixedly installed inside the bottom of the material preparation hopper 1. Wires 7 are fixedly connected to the bottom of each of the four thermocouples 6. The other end of the wires 7 is electrically connected to the input terminal of the controller 4.

[0023] Thermocouple 6 is electrically connected to the input terminal of controller 4 via wire 7. The output terminal of controller 4 is electrically connected to the input terminal of buzzer 5. When the rubber material enters the interior of the preparation hopper 1, the four thermocouples 6 on the bottom surface of the preparation hopper 1 are inserted into the rubber material under the action of gravity to measure the temperature. Then, the temperature data is transmitted to controller 4 via wire 7. After receiving the data, controller 4 compares the collected discharge temperature data and records the highest temperature. If the measured temperature exceeds the standard range, buzzer 5 is activated to issue a material obstruction alarm.

[0024] The bottom of the mounting frame 3 is fixedly connected to a fixing block 8, the outer surface of the fixing block 8 is movably sleeved with a threaded rod 9, one end of the outer surface of the threaded rod 9 is movably sleeved with a rectangular plate 10, and the top of the rectangular plate 10 is fixedly connected to the bottom of the mounting frame 3.

[0025] The design of the fixing block 8 and the rectangular plate 10 serves to install and support the threaded rod 9.

[0026] Among them, the outer surface of the threaded rod 9 is threaded with a movable plate 11. The top of the movable plate 11 is movably connected to the bottom of the mounting frame 3. The outer side of the movable plate 11 is hinged with a connecting rod 12. The other end of the connecting rod 12 is hinged with an L-shaped plate 13. There are two L-shaped plates 13. The inner side of the two L-shaped plates 13 is movably connected to the outer side of the two mounting brackets 2 respectively. The inner side of the two L-shaped plates 13 is fixedly connected with a pin 14. The inner side of the pin 14 passes through the mounting bracket 2 and the mounting frame 3 in sequence and extends into the interior of the mounting frame 3.

[0027] Rotating the threaded rod 9 will cause the movable plate 11 to move horizontally, which in turn causes the two connecting rods 12 to rotate and drive the two L-shaped plates 13 to move towards each other. This, in turn, causes the two pins 14 to move towards each other and insert into the interior of the mounting frame 3 to install and fix the mounting frame 3, thus achieving the purpose of facilitating the installation and disassembly of the mounting frame 3.

[0028] The bottom of the mounting frame 3 is provided with a sliding groove 15, and a limiting block 16 is movably connected inside the sliding groove 15. The bottom of the limiting block 16 is fixedly connected to the outer surface of the L-shaped plate 13.

[0029] The design of the slide 15 and the limiting block 16 serves to limit the L-shaped plate 13, ensuring the stability of the horizontal movement of the L-shaped plate 13.

[0030] There are two limit blocks 16, and both limit blocks 16 are T-shaped.

[0031] The two limiting blocks 16 are T-shaped, which prevents the two L-shaped plates 13 from detaching from the bottom of the mounting frame 3.

[0032] The top of the mounting frame 3 is fixedly connected to a damper 17, the top of the damper 17 is fixedly connected to the bottom of the hopper 1, and a spring 18 is fixedly installed at the bottom of the inner cavity of the damper 17, with the top of the spring 18 fixedly connected to the top of the inner cavity of the damper 17.

[0033] The design of damper 17 and spring 18 serves to reduce the vibration of mounting frame 3.

[0034] There are two dampers 17, both of the same size, and they are symmetrical about the center of the mounting frame 3.

[0035] The design of two dampers 17 has a more significant effect on mitigating the overall damping effect of the mounting frame 3.

[0036] Working principle and usage process of this utility model:

[0037] When it is necessary to measure the temperature of the rubber compound after discharge from the internal mixer, the rubber compound enters the preparation hopper 1. Under the action of gravity, the four thermocouples 6 on the bottom of the preparation hopper 1 are inserted into the rubber compound to measure the temperature. Then, the temperature data is transmitted to the controller 4 through the wire 7. After receiving the data, the controller 4 compares the collected discharge temperature data and records the highest temperature. If the measured temperature exceeds the standard range, the buzzer 5 is activated to issue a material obstruction alarm.

[0038] To facilitate maintenance of controller 4, rotating threaded rod 9 will cause movable plate 11 to move horizontally, which in turn causes two connecting rods 12 to rotate and drive two L-shaped plates 13 to move in opposite directions. This causes the two pins 14 to move in opposite directions and separate from mounting bracket 2 and mounting frame 3, releasing the fixing effect on mounting frame 3. This achieves the purpose of easy installation and disassembly of mounting frame 3, so as to facilitate maintenance of controller 4.
