Description

Technical Field

[0001] The invention relates to the technical field of temperature detection devices, and in particular to an automatic rubber material temperature detection device for a rubber extrusion tablet press. Background Art

[0002] Rubber mixing is the core process in the production of rubber products, with tires as a typical example. The rubber extruder is an auxiliary machine of the internal mixer, which is used to continuously extrude the lumpy rubber material discharged intermittently from the internal mixer, which is convenient for subsequent cooling and turnover, and has a high degree of automation. At the same time, the smoke and dust accompanying the rubber material discharged from the internal mixer can be sealed to protect the workshop environment.

[0003] Mixing quality is the core factor that affects the quality of the final product. For internal mixers, the condition for ending each cycle is to reach the set temperature of the rubber compound. Therefore, the accuracy difference between the actual discharge temperature of the internal mixer and the temperature set by the electrical program is very critical. In the daily production quality control of downstream customers, the actual temperature of the rubber compound discharged from the internal mixer will be tested to verify the discharge accuracy of the internal mixer. At present, after the internal mixer is discharged, the rubber compound is quickly manually discharged from the feed chute of the extruder tablet press (see the attached document below). Figure 1 Detect the temperature of the rubber compound. The detection point is located at a relatively high position, and the operator has a high safety risk of climbing up and down; when the door of the material trough is opened to detect the temperature of the rubber compound, the smoke from the rubber discharge of the internal mixer will also be discharged to pollute the workshop environment and affect the health of the operator; the operator will also be at risk of being hit by the rubber discharged from the internal mixer when he leans into the material trough to work; in addition, each time the rubber temperature is detected, the extruder tablet press needs to be temporarily stopped and restarted after the detection is completed. The extruder tablet press is frequently started with load, and the instantaneous load impact is large, which affects the life of related parts. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic detection device for the temperature of rubber material, so as to realize automatic detection of the temperature of rubber material, reduce labor intensity and operation risks, improve the workshop environment and the service life of equipment, and ensure and improve the service life of equipment.

[0005] The technical scheme adopted by the present invention to achieve the above-mentioned purpose is as follows: a device for automatically detecting the temperature of a rubber material, comprising a material tank 1, a temperature measuring thermocouple 2, a guide sleeve 3, a cylinder 4, a cylinder seat 5, and an electronic control system 6; the temperature measuring thermocouple 2 is connected to the piston rod of the cylinder 4, and the cylinder 4 is fixed on the cylinder seat 5;

[0006] The electronic control system 6 is connected to the cylinder 4;

[0007] A small hole is opened on the side of the material trough 1, and the guide sleeve 3 is installed on the material trough 1 through the small hole; the temperature measuring thermocouple 2 is inserted into the guide sleeve 3 to form a seal;

[0008] The electronic control system 6 is electrically interlocked with the upper internal mixer; the rubber material discharged from the upstream internal mixer falls into the material tank 1; after receiving the signal that the internal mixer has finished discharging, the electronic control system 6 issues a command, and the cylinder 4 pushes the temperature measuring thermocouple 2 to insert into the material tank 1 to detect the temperature of the rubber material, and the temperature signal is fed back to the electronic control system 6, thereby realizing automatic detection of the rubber material temperature;

[0009] After the test is completed, the cylinder 4 pulls back the temperature measuring thermocouple 2; the temperature measuring thermocouple 2 cooperates with the guide sleeve 3 to ensure that the seal is leak-proof; during this test process, the rubber extrusion tablet press runs normally and continuously without stopping.

[0010] The temperature measuring thermocouple 2 has a high thermal response speed to ensure the detection accuracy, and the accuracy is T 63.2 Up to 10S.

[0011] The guide sleeve 3 is internally made of composite material to guide the temperature measuring thermocouple 2 .

[0012] The invention has the following beneficial effects: the temperature measuring thermocouple cooperates with the guide sleeve to ensure a leak-proof seal. The guide sleeve is made of composite materials to guide the temperature measuring thermocouple. In the detection process, the temperature of the rubber material is automatically detected; the rubber extrusion tablet press can operate normally and continuously without stopping.

[0015] The present patent will be further described below in conjunction with the accompanying drawings.

[0016] The existing rubber material temperature detection structure is as follows: there is a door on the material trough and an auxiliary staircase platform is provided. When the rubber material temperature needs to be detected, for safety reasons, the operator must first stop the equipment, then walk to the top of the staircase platform and open the door, detect the rubber material temperature with a handheld thermometer and record it. After the detection is completed, close the door, walk down the platform and restart the equipment to resume normal production. This method is cumbersome to operate and has great safety risks. In addition, when the door is opened, the smoke and dust in the material trough will be released, polluting the environment and damaging the health of the operator. Frequently starting the equipment with load will also have an adverse effect on the service life of related parts.

[0017] The present invention sees Figure 1The action of detecting the temperature of the rubber compound is fully automated, and the equipment can operate normally and continuously without stopping during the detection. The action of the device is electrically interlocked with the upstream internal mixer, and the operation is safe and reliable. At the same time, it also improves the workshop environment quality and improves the service life of the equipment.

[0018] The rubber material discharged from the upstream internal mixer falls into the material tank 1.

[0019] Thermocouple 2 has high thermal response speed to ensure detection accuracy, T 63.2 Up to 10S.

[0020] The temperature measuring thermocouple 2 is connected to the piston rod of the cylinder 4 , and the cylinder 4 is fixed on the cylinder seat 5 .

[0021] The electronic control system 6 is electrically interlocked with the upper internal mixer, and issues a command after receiving the signal that the internal mixer has completed discharging. The cylinder pushes the temperature measuring thermocouple 2 to be inserted into the material chute 1 to detect the temperature of the rubber material, and the temperature signal is fed back to the electronic control system, thereby realizing automatic detection of the rubber material temperature.

[0022] After the test is completed, the cylinder 4 pulls back the temperature measuring thermocouple 2.

[0023] The temperature measuring thermocouple 2 cooperates with the guide sleeve 3 to ensure a leak-proof seal. The guide sleeve 3 is made of composite material to guide the temperature measuring thermocouple 2.

[0024] During this testing process, the rubber extrusion tablet press runs normally and continuously without stopping.
