Description

Technical Field

[0001] This utility model relates to the field of ingot temperature measurement technology, and in particular to an automatic ingot temperature measurement device that uses an electromagnetic reversing valve to control the reversal of compressed air. Background Technology

[0002] A dual-needle surface thermocouple is a temperature-sensing element specifically designed to measure the surface temperature of an object. It uses a compression spring to tightly press the thermocouple tip against the surface of the object being measured, thereby improving the reliability and accuracy of the measurement. This type of thermocouple is widely used in many fields such as industry, medicine, and scientific research. For example, in the plastic extruder, textile, and food processing industries, its main function is to monitor and control the temperature during the production process to ensure product quality and production safety. In addition, dual-needle surface thermocouples can also be used to measure ambient temperature, including indoor and outdoor temperatures.

[0003] The current use of dual-needle surface thermocouples has the following drawbacks:

[0004] 1) Production personnel need to measure the temperature of the ingot by holding a double-needle surface thermocouple and contacting it with the surface of the ingot (aluminum ingot). Then, they manually input the measured temperature data into the computer. This process is not only time-consuming and labor-intensive, but also poses a risk of burns due to the extremely high temperature of the ingot. In the high-temperature environment of summer, this operation method may also increase the risk of heatstroke for employees.

[0005] 2) Since temperature measurement relies on manual operation by production personnel, even for the same ingot, the recorded temperature data may be inaccurate due to slight deviations in the measurement position by the production personnel. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic temperature measuring device for ingots, which controls the gas reversal through an electromagnetic reversing valve, causing the cylinder piston rod to push out / retract, thereby moving the thermocouple to / out of the working position and standardizing the temperature measuring process.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An automatic temperature measuring device for ingots includes a high-pressure air source, a pneumatic triplet, an electromagnetic reversing valve, a cylinder, a double-needle surface thermocouple, a roller conveyor, and a support. The ingot moves along the roller conveyor. The high-pressure air source is connected to the air inlet of the pneumatic triplet via a supply pipeline. The electromagnetic reversing valve has a P port, an A port, and a B port. The air outlet of the pneumatic triplet is connected to the P port of the electromagnetic reversing valve via an outlet pipeline. The cylinder includes a plug chamber, a rod chamber, and a piston rod. The A port of the electromagnetic reversing valve is connected to the plug chamber via a plug chamber pipeline, and the B port of the electromagnetic reversing valve is connected to the rod chamber via a rod chamber pipeline. The cylinder is fixed to the top of the support so that the height of the piston rod is higher than the height of the roller conveyor. The double-needle surface thermocouple is fixed to the head of the piston rod via a connector. When the head of the piston rod is pushed out, the probe of the double-needle surface thermocouple is pushed out synchronously with the piston rod to cooperate with the surface of the ingot for temperature measurement.

[0009] Furthermore, the bracket includes an integrally formed vertical bracket and a horizontal bracket, the electromagnetic reversing valve and the pneumatic triplet are fixed at intervals on the side of the vertical bracket, and the cylinder is fixed at the upper end of the horizontal bracket.

[0010] Furthermore, the connector includes an adapter plate and a clamp. The adapter plate includes an integrally formed vertical plate and a horizontal plate. The vertical plate is fixedly sleeved on the head of the piston rod, and the double-needle surface thermocouple is fixed to the upper end of the horizontal plate by the clamp.

[0011] Furthermore, the roller conveyor is installed on the inner side of the bearing housing.

[0012] Furthermore, the bearing housing is fixed to the upper end of the base.

[0013] When measuring temperature, the compressed air from the high-pressure air source is switched to the next direction by an electromagnetic reversing valve. The compressed air enters the cylinder piston chamber from the piston chamber pipe to drive the piston rod to move.

[0014] After the temperature measurement is completed, the electromagnetic reversing valve switches the direction of compressed air flow again, and the compressed air enters the cylinder rod chamber from the rod chamber pipe, causing the piston rod to retract.

[0015] The working position of the thermocouple on the piston rod can be flexibly adjusted simply by switching the direction of the electromagnetic reversing valve, thus standardizing the temperature measurement process.

[0016] This invention enables automatic temperature measurement of thermocouples through remote control of the electromagnetic reversing valve, allowing production personnel to perform temperature measurement operations without having to approach the high-temperature aluminum ingot, thus avoiding the safety hazard of burns during the ingot temperature measurement process.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] This embodiment discloses an automatic temperature measuring device for ingots, such as... Figure 1 As shown, it includes a high-pressure air source 1, a pneumatic triplet 2, an electromagnetic reversing valve 3, a cylinder 4, a double-needle surface thermocouple 5, a roller conveyor 6, and a support 8. The ingot 7 moves along the roller conveyor 6. The roller conveyor 6 is installed on the inner side of the bearing seat 11. The bearing seat 11 protects the roller conveyor 6. The bearing seat 11 is fixed to the upper end of the base 12. The bearing seat 11 supports the roller conveyor 6 and the bearing seat 11 as a whole on the ground or workbench.

[0028] High-pressure air source 1 is connected to the air inlet of pneumatic triplet 2 via an air supply pipeline. Electromagnetic directional valve 3 has ports P, A, and B. Figure 2 As shown, the air outlet of the pneumatic triplet 2 is connected to the P port of the solenoid directional valve 3 through the air outlet pipe 31. The cylinder 4 includes a plug chamber 41, a rod chamber 42 and a piston rod 43. The A port of the solenoid directional valve 3 is connected to the plug chamber 41 through the plug chamber pipe 32, and the B port of the solenoid directional valve 3 is connected to the rod chamber 42 through the rod chamber pipe 33.

[0029] The dual-needle surface thermocouple 5 is fixed to the head of the piston rod 43 via a connector, such as... Figure 2As shown, the connector specifically includes an adapter plate 9 and a clamp 10. The adapter plate 9 includes an integrally formed vertical plate 91 and a horizontal plate 92. The vertical plate 91 is fixedly sleeved on the head of the piston rod 43, and the double-needle surface thermocouple 5 is fixed to the upper end of the horizontal plate 92 by the clamp 10.

[0030] When the head of the piston rod 43 is ejected, the probe of the double-needle surface thermocouple 5 is ejected synchronously with the piston rod 43, so as to cooperate with the surface of the ingot 7 for temperature measurement.

[0031] In this embodiment, during manufacturing, the height of the measuring point is calculated based on the height of the roller conveyor 6 plus the height of the ingot 7. Then, a bracket 8 is made based on this height to support and install the cylinder 6, the pneumatic triplet 2, and the electromagnetic reversing valve 3, so that the height of the piston rod 43 is higher than the height of the roller conveyor 6.

[0032] like Figure 2 As shown, the bracket 8 includes an integrally formed vertical bracket 81 and a horizontal bracket 82. The electromagnetic reversing valve 3 and the pneumatic triplet 2 are fixed at intervals on the side of the vertical bracket 81, and the cylinder 4 is fixed at the upper end of the horizontal bracket 82.

[0033] In this embodiment, the pneumatic triplet 2 is model AL2000 with a rated pressure of 1MPa; the electromagnetic directional valve 3 is model SV25-211D with a voltage of AC220V; and the cylinder 4 is model SC40×600S.

[0034] The automatic ingot temperature measuring device of this embodiment includes the following steps during assembly:

[0035] 1) Connect the compressed air from the high-pressure air source 1 to the air inlet of the pneumatic triplet 2 through the air supply pipeline;

[0036] 2) The pneumatic triplet 2 outlet delivers compressed air to the P port of the solenoid directional valve 3 through the outlet pipe 31;

[0037] 3) Compressed air is led out from ports A and B of the solenoid directional valve 3 respectively, and connected to the plug chamber 41 and rod chamber 42 of the cylinder 4 through the plug chamber pipeline 32 and the rod chamber pipeline 33.

[0038] 4) Connect the piston rod 43 to an adapter plate 9, and the double-needle surface thermocouple 5 is mounted on the adapter plate 9 through the clamp 10.

[0039] The automatic ingot temperature measuring device in this embodiment includes the following steps during the temperature measuring process:

[0040] When a test ingot 7 moves to the temperature measuring point on the roller conveyor 6, the test ingot 7 stops moving forward due to the sensing by a photoelectric sensor or a proximity switch; the sensing here is existing technology and will not be described in detail.

[0041] Compressed air from high-pressure air source 1 undergoes pressure regulation and lubrication treatment by pneumatic triplet 2, and then flows through solenoid directional valve 3 for directional adjustment. Solenoid directional valve 3 outputs from port A and inputs from port B. Compressed air enters plug chamber 41 through plug chamber pipeline 32. The forward movement of plug chamber 41 compresses rod chamber 42, and the gas in rod chamber 42 is discharged through rod chamber pipeline 33. (See also...) Figure 2 The arrow markings indicate that this step ultimately pushes the head of piston rod 43 outwards.

[0042] The dual-needle surface thermocouple 5 and the piston rod 43 move synchronously until the head probe of the dual-needle surface thermocouple 5 contacts the surface of the ingot 7 to perform the temperature measurement task.

[0043] After completing the temperature measurement task, the temperature data is transmitted from the dual-needle surface thermocouple 5 to the host computer for storage, and a temperature curve is plotted.

[0044] The electromagnetic reversing valve 3 switches the flow direction of compressed air again. The output of the electromagnetic reversing valve 3 is through port B and the input is through port A. Compressed air enters the rod chamber 42 through the rod chamber pipeline 33. The rod chamber 42 retracts, which compresses the plug chamber 41. The gas in the plug chamber 41 is discharged through the plug chamber pipeline 32, and the piston rod 43 retracts.

[0045] Ingot 7 continues to move on roller conveyor 6, waiting for the next ingot 7 to be tested.

[0046] Through the above steps, automated temperature measurement of ingot 7 can be achieved.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
