Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing and production technology, specifically a temperature measuring device for aluminum rod processing. Background Technology

[0002] Before processing, aluminum rods are preheated using a processing device. Preheating softens the aluminum rods, reducing the mechanical force required for extrusion (e.g., reducing extrusion pressure by 20%), which can prevent equipment overload or damage. After heating, the activity of aluminum atoms increases, making it easier to fill complex mold structures and reducing defects such as surface cracks or incomplete filling. However, if the preheating temperature of the aluminum rod is insufficient, the aluminum rod will become too hard, making extrusion difficult, which may cause mold jamming or equipment damage, forcing a reduction in extrusion speed and affecting production efficiency. If the temperature is too high, the grains will grow excessively, reducing the mechanical properties of the material, and surface oxidation will intensify, increasing the scrap rate. It is necessary to significantly reduce the extrusion speed to avoid overheating defects. Therefore, temperature measurement of the aluminum rods before extrusion after preheating is a core control method to ensure product quality and efficiency in the extrusion process.

[0003] Existing technology for aluminum rod temperature measurement involves installing an infrared thermometer on the inner wall of the furnace outlet. After the aluminum rod is discharged, the infrared thermometer measures its temperature. If the temperature measured by the temperature measuring component is within the acceptable range, the conveying mechanism transports the aluminum rod to the extrusion process. If the temperature measured by the temperature measuring component is outside the acceptable range, the aluminum rod is lifted by a hoisting mechanism during the conveying process and sent to the furnace for reheating. This temperature measuring device can measure the temperature of the preheated aluminum rod in a timely manner, ensuring product quality and efficiency.

[0004] The infrared thermometer is fixedly installed on the inner wall of the outlet of the heating furnace. After the aluminum rod is discharged, its surface is close to the infrared thermometer, which makes the measured temperature more accurate. However, for aluminum rods of different diameters, the distance between the surface of the aluminum rod and the temperature probe will be different when passing through the temperature probe. As the distance between the surface of the aluminum rod and the temperature probe increases, the temperature measured by the temperature probe will be lower than the actual surface temperature of the aluminum rod. This will result in errors when measuring the temperature of aluminum rods of different diameters, reducing the accuracy of the temperature measurement.

[0005] It is concluded that existing technologies have difficulty in achieving adaptive adjustment of the aluminum rod position to maintain a constant temperature measurement interval based on the diameter of the aluminum rod during temperature measurement. Therefore, this invention makes an innovative design in the temperature measurement device used for aluminum rod processing. Summary of the Invention

[0006] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a temperature measuring device for aluminum rod processing, thereby solving the problem mentioned in the background art of difficulty in adaptively adjusting the position of the aluminum rod according to its diameter to maintain a constant temperature measuring interval during temperature measurement.

The sprocket one is installed on the frame via a central shaft, and a sprocket two meshing with the chain is installed at the output end of the motor. The outer wall of the chain on the chain conveyor assembly is fixedly fitted with a conveyor rod.

[0009] Preferably, a thermometer is installed on the inner wall of the temperature measuring bracket, and a limit rail is installed inside the temperature measuring bracket.

[0010] Preferably, a first sealing plug is slidably connected to the inner wall of the first sealing cylinder, the top of the first sealing plug is rotatably connected to the bottom of the support column through a U-shaped connecting frame, a first conveying plate is fixedly connected to the top of the support column, a first spring is fixedly connected to the bottom of the first conveying plate, and the bottom of the first spring is fixedly connected to the top of the first sealing cylinder.

[0011] Preferably, the top of the first sealing cylinder is provided with an eccentric channel, and a guide rod is fixedly installed on the inner wall of the eccentric channel; The side wall of the support column away from the second sealing cylinder is fitted with the inner wall of the eccentric channel, and the outer wall of the support column is provided with an inclined channel, through which the guide rod passes.

[0012] Preferably, the top of the connecting pipe is provided with a receiving cavity, and a connecting rod is fixedly installed on the inner wall of the receiving cavity, and the connecting rod is rotatably sleeved with the top of the flow-retardant plate; The flow-retardant plate has a semi-circular shape, and the curvature of the outer wall of the flow-retardant plate is the same as the curvature of the inner wall of the connecting pipe.

[0013] Preferably, a second sealing plug is slidably connected to the inner wall of the second sealing cylinder, the top of the second sealing plug is fixedly connected to the bottom of the second spring, a lifting plate is fixedly connected to the top of the second spring, the outer wall of the lifting plate is slidably connected to the inner wall of the second sealing cylinder, a lifting column is fixedly connected to the top of the lifting plate, the lifting column is slidably sleeved with the second sealing cylinder, an elastic telescopic rod is fixedly connected to the top of the lifting column, and a second conveying plate is fixedly connected to the top of the elastic telescopic rod.

[0014] Preferably, a rotating roller is provided on the top of both the second conveyor plate and the first conveyor plate; The second conveyor plate is inclined.

[0015] Preferably, a fixing frame is fixedly connected to the outer wall of the second sealing cylinder, a third spring is fixedly connected to the inner wall of the fixing frame, a locking block is fixedly connected to one end of the third spring, and the outer wall of the locking block is slidably connected to the inner wall of the fixing frame. One end of the locking block extends into the interior of the second sealing cylinder, and the locking block is slidably connected to the second sealing cylinder. The side of the end of the locking block extending into the interior of the second sealing cylinder is inclined.

[0016] Preferably, the top of the card block is provided with a sloping groove; The top of the fixed frame has a through hole, and the bottom of the second conveying plate is fixedly connected to a guide rod. The bottom of the guide rod passes through the through hole and extends into the interior of the fixed frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the impact force generated by the weight and acceleration of the aluminum rod to compress the hydraulic oil, thus compressing the second spring. After the second spring is charged, the released energy propels the aluminum rod upwards. A thermometer is mounted above the second conveyor plate. As the aluminum rod moves upwards, it is blocked by a limiting rail. The temperature probe is positioned between the limiting rails, with the surface of the aluminum rod close to the probe. The probe measures the temperature of the aluminum rod. This invention enables aluminum rods of different diameters to move upwards to the probe position during temperature measurement. Since the surfaces of aluminum rods of different diameters are close to the probe during measurement, the distance between the probe and the aluminum rods of different diameters is always the same. This prevents errors caused by a large distance between the aluminum rod surface and the probe due to a smaller diameter. Compared to existing aluminum rod processing temperature measuring devices, this invention has the advantage of adaptively adjusting the aluminum rod position according to its diameter to maintain a constant temperature measurement interval, thus improving measurement accuracy. In addition, multiple limit bars are vertically spaced below the temperature measuring instrument, and the temperature probe is located between the gaps of the limit bars. After the aluminum rod moves upward, it will be blocked by the limit bars. When measuring the temperature of a larger diameter aluminum rod, after the second conveyor plate moves upward a short distance and the surface of the aluminum rod comes into contact with the limit bars, the elastic telescopic rod will retract under pressure, so that the surface of the aluminum rod will not be damaged due to the force of contact with the limit bars. The limit bars can isolate the aluminum rod and the temperature probe, so the aluminum rod will not damage the temperature probe on the temperature measuring instrument. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 11 The present invention provides a technical solution: a temperature measuring device for aluminum rod processing, including a frame 1, a chain conveyor group 2 installed on the frame 1 and a temperature measuring bracket 3 suspended on the discharge end of the frame 1, and further including a first sealing cylinder 4 and a second sealing cylinder 6 installed below the temperature measuring bracket 3, a lifting component installed on the second sealing cylinder 6 that adapts to the diameter of the aluminum rod and maintains a constant temperature measuring interval, a support column 42 installed on the first sealing cylinder 4 for driving the lifting component to adaptively adjust the position of the aluminum rod according to the diameter of the aluminum rod, and a connecting pipe 5 with a one-way flow blocking function installed between the first sealing cylinder 4 and the second sealing cylinder 6; The lifting component includes a second spring 62 that adaptively stores and charges energy according to the diameter of the aluminum rod, and then releases the energy to drive the aluminum rod upward toward the temperature probe. The inside of the connecting pipe 5 is fitted with a flow-damping plate 52 for unidirectional flow obstruction.

[0032] In this embodiment, the weight of the aluminum rod and the impact force generated by gravitational acceleration press the support column 42 downwards. The support column 42 compresses the hydraulic oil, causing it to enter the second sealing cylinder 6 through the connecting pipe 5. The hydraulic oil compresses the second spring 62, and then the second spring 62, after storing and charging its energy, releases the energy to move the aluminum rod upwards. This ensures that aluminum rods of different diameters can be moved upwards to the temperature probe position during temperature measurement, guaranteeing that the distance between aluminum rods of different diameters and the temperature probe is the same during temperature measurement. This prevents a large distance between the surface of the aluminum rod and the temperature probe due to the smaller diameter of the aluminum rod, which could lead to measurement errors.

[0033] The chain conveyor assembly 2 includes a motor installed at the bottom of the frame 1, a chain installed on one side of the frame 1, and a sprocket 1 installed on the frame 1 and meshing with the chain. The sprocket 1 is installed on the frame 1 through a central shaft, and a sprocket 2 that meshes with the chain is installed at the output end of the motor. A conveyor rod 21 is fixedly installed on the outer wall of the chain on the chain conveyor group 2.

[0034] In this embodiment, the motor drives the chain to rotate through the sprocket 2, and the chain drives multiple conveying rods 21 to rotate. The conveying rods 21 can then move the aluminum rod towards the temperature measuring instrument. The overall positional movement of the conveying rods 21 will simultaneously move the aluminum rod, which will be conveyed towards the temperature measuring bracket 3.

[0035] A temperature measuring instrument is installed on the inner wall of the temperature measuring bracket 3, and a limit rail is installed inside the temperature measuring bracket 3.

[0036] In this embodiment, the temperature measuring bracket 3 is composed of two inverted U-shaped frames and a connecting plate in the middle. The temperature measuring instrument is installed on the connecting plate in the middle. Multiple limit rails are vertically spaced below the temperature measuring instrument. The temperature measuring probe is located between the gaps of the limit rails. The limit rails can isolate the aluminum rod and the temperature measuring probe, so that the aluminum rod will not damage the temperature measuring probe on the temperature measuring instrument.

[0037] The inner wall of the first sealing cylinder 4 is slidably connected to a first sealing plug 41. The top of the first sealing plug 41 is rotatably connected to the bottom of the support column 42 through a U-shaped connecting frame. The top of the support column 42 is fixedly connected to a first conveying plate 43. The bottom of the first conveying plate 43 is fixedly connected to a first spring 44. The bottom of the first spring 44 is fixedly connected to the top of the first sealing cylinder 4.

[0038] In this embodiment, after the aluminum rod falls onto the first conveying plate 43, the first conveying plate 43 is pressed down by gravity onto the support column 42 and the first sealing plug 41. The first sealing plug 41 will squeeze the hydraulic oil at its bottom into the interior of the second sealing cylinder 6 through the connecting pipe 5. The second sealing plug 61 will move upward under the pressure of the hydraulic oil and squeeze the second spring 62, so that the second spring 62 is in a compressed state. After the aluminum rod is separated from the first conveying plate 43, the first conveying plate 43 will drive the support column 42 and the first sealing plug 41 to reset through the first spring 44.

[0039] The top of the first sealing cylinder 4 is provided with an eccentric channel, and a guide rod 45 is fixedly installed on the inner wall of the eccentric channel. The side wall of the support column 42 away from the second sealing cylinder 6 is fitted with the inner wall of the eccentric channel, and the outer wall of the support column 42 is provided with an inclined channel, through which the guide rod 45 passes.

[0040] In this embodiment, when the support column 42 moves downward, the inclined channel on the support column 42 will change its angle due to the limit of the guide rod 45. Therefore, the top of the support column 42 will cause the first conveyor plate 43 to tilt, and the aluminum rod will roll along the first conveyor plate 43 due to the unstable center of gravity.

[0041] The top of the connecting pipe 5 is provided with a receiving cavity, and a connecting rod 51 is fixedly installed on the inner wall of the receiving cavity. The connecting rod 51 is rotatably sleeved with the top of the flow-retardant plate 52. The flow-retardant plate 52 has a semi-circular shape, and the curvature of the outer wall of the flow-retardant plate 52 is the same as the curvature of the inner wall of the connecting pipe 5.

[0042] In this embodiment, the position of the flow-damping plate 52 is closer to the first sealing cylinder 4 inside the receiving cavity. When hydraulic oil enters the first sealing cylinder 4 through the connecting pipe 5, the flow-damping plate 52 rotates due to the flow rate of the hydraulic oil, so the flow-damping plate 52 will not have a significant impact on the flow rate of the hydraulic oil. When the hydraulic oil inside the second sealing cylinder 6 flows into the first sealing cylinder 4 through the connecting pipe 5, the side of the flow-damping plate 52 closest to the second sealing cylinder 6 is subjected to force, while the other side of the top of the flow-damping plate 52 is attached to the inner wall of the receiving cavity. This means that the side of the flow-damping plate 52 closest to the second sealing cylinder 6 has no space to rotate when subjected to the force of the hydraulic oil flow. Therefore, the hydraulic oil flows back into the first sealing cylinder 4 more slowly, achieving a unidirectional flow-damping effect.

[0043] The inner wall of the second sealing cylinder 6 is slidably connected to a second sealing plug 61. The top of the second sealing plug 61 is fixedly connected to the bottom of the second spring 62. The top of the second spring 62 is fixedly connected to a lifting plate 63. The outer wall of the lifting plate 63 is slidably connected to the inner wall of the second sealing cylinder 6. The top of the lifting plate 63 is fixedly connected to a lifting column 64. The lifting column 64 is slidably sleeved with the second sealing cylinder 6. The top of the lifting column 64 is fixedly connected to an elastic telescopic rod 65. The top of the elastic telescopic rod 65 is fixedly connected to a second conveying plate 66.

[0044] Both the top of the second conveyor plate 66 and the first conveyor plate 43 are equipped with rotating rollers; The second conveyor plate 66 is inclined.

[0045] In this embodiment, the rotating rollers at the top of the second conveyor plate 66 and the first conveyor plate 43 can provide a certain frictional resistance. When the aluminum rod falls onto the first conveyor plate 43, the rotating rollers can prevent the aluminum rod from detaching directly from the first conveyor plate 43 due to inertia. After the first conveyor plate 43 tilts, the aluminum rod will roll along the first conveyor plate 43 onto the second conveyor plate 66. Since the second conveyor plate 66 itself is tilted, the aluminum rod will roll along the second conveyor plate 66. However, the rotating rollers on the second conveyor plate 66 can buffer and slow down the aluminum rod, so that the aluminum rod will not detach from the second conveyor plate 66 when it moves upward. After the second conveyor plate 66 moves the aluminum rod upward to measure the temperature, the aluminum rod will roll down onto the conveyor rod 21 of the chain conveyor group 2 on the other side of the temperature measuring bracket 3.

[0046] The outer wall of the second sealing cylinder 6 is fixedly connected to a fixed frame 7, the inner wall of the fixed frame 7 is fixedly connected to a third spring 71, one end of the third spring 71 is fixedly connected to a locking block 72, and the outer wall of the locking block 72 is slidably connected to the inner wall of the fixed frame 7. One end of the locking block 72 extends into the interior of the second sealing cylinder 6, and the locking block 72 is slidably connected to the second sealing cylinder 6. The side of the end of the locking block 72 extending into the interior of the second sealing cylinder 6 is inclined.

[0047] The top of the card block 72 is provided with a sloping groove, the top of the fixed frame 7 is provided with a through hole, and the bottom of the second conveying plate 66 is fixedly connected with a guide rod 73. The bottom of the guide rod 73 passes through the through hole and extends into the interior of the fixed frame 7.

[0048] In this embodiment, the second conveying plate 66 is compressed by the weight of the aluminum rod, which compresses the elastic telescopic rod 65. The second conveying plate 66 will drive the guide rod 73 to move downward a short distance. The bottom of the guide rod 73 presses the locking block 72 through the inclined groove on the top of the locking block 72, so that the locking block 72 extends to one end of the second sealing cylinder 6 and no longer limits the lifting plate 63. The restoring force of the second spring 62 will drive the second conveying plate 66 to move upward through the lifting plate 63 and the lifting column 64. After the aluminum rod has finished measuring the temperature and is separated from the second conveying plate 66, the hydraulic oil drives the second sealing plug 61 to reset downward through negative pressure. Since the side of the locking block 72 extending into the second sealing cylinder 6 is a side, when the lifting plate 63 moves downward, the inclined surface of the locking block 72 will cause the locking block 72 to retract back into the fixed frame 7. The lifting plate 63 can then reset downward to below the moving locking block 72.

[0049] Working principle: When using this temperature measuring device for aluminum rod processing, the preheated aluminum rod is first hoisted onto the conveyor rod 21 using an external lifting mechanism. Figure 1 As shown, the motor drives the chain to rotate through the second sprocket, and the chain drives multiple conveyor rods 21 to rotate, which in turn drives the aluminum rod to move towards the thermometer. When the aluminum rod detaches from the conveyor rod 21, it will fall onto the first conveyor plate 43. Figure 2 As shown, the position of the first conveyor plate 43 is lower than the height of the conveyor rod 21. When the aluminum rod falls onto the first conveyor plate 43, it will press down on the first conveyor plate 43 due to its own weight and acceleration. The first conveyor plate 43 is pressed down by gravity on the support column 42 and the first sealing plug 41. The first sealing plug 41 will squeeze the hydraulic oil at its bottom into the interior of the second sealing cylinder 6 through the connecting pipe 5. The second sealing plug 61 will move upward under the pressure of the hydraulic oil and squeeze the second spring 62, so that the second spring 62 is in a compressed state. During this process, since the support column 42 is also moving downward, the inclined channel on the support column 42 will change its angle due to the limit of the guide rod 45. Therefore, the top of the support column 42 will drive the first conveyor plate 43 to rotate towards the second conveyor plate 66, and the aluminum rod will roll along the first conveyor plate 43 onto the second conveyor plate 66. The second conveyor plate 66, under the weight of the aluminum rod, compresses the elastic telescopic rod 65. The second conveyor plate 66 then drives the guide rod 73 to move downward a short distance. The bottom of the guide rod 73 presses the locking block 72 through the inclined groove on the top of the locking block 72, causing the locking block 72 to move into the fixed frame 7. Therefore, the end of the locking block 72 extending to the second sealing cylinder 6 no longer limits the lifting plate 63. The restoring force of the second spring 62 will drive the second conveyor plate 66 to move upward through the lifting plate 63 and the lifting column 64. Since the second conveyor plate 66 is located directly below the temperature probe of the thermometer, the second conveyor plate 66 drives the aluminum rod to move upward, causing the aluminum rod to move towards the temperature probe of the thermometer, so that the top of the aluminum rod is close to the bottom of the limiting rail. Each aluminum rod will be driven to move upward and close to the bottom of the limiting rail during temperature measurement, so that the position of the aluminum rod can be adaptively adjusted according to the diameter of the aluminum rod to maintain a constant temperature measurement interval. After the aluminum rod rolls onto the second conveyor plate 66, the first conveyor plate 43 is no longer subjected to the weight of the aluminum rod. The first conveyor plate 43 will move upward to its original position via the first spring 44. The first conveyor plate 43 will drive the first sealing plug 41 to move upward. The negative pressure inside the first sealing cylinder 4 will draw the hydraulic oil back into the first sealing cylinder 4 through the connecting pipe 5. At this time, the flow damper 52 inside the connecting pipe 5 will rotate to a vertical position due to the flow rate of the hydraulic oil. The flow damper 52 will block half of the flow cavity inside the connecting pipe 5, so the hydraulic oil will flow back more slowly. The second spring 62 will be resisted by the hydraulic oil at the bottom and no longer limited by the stop block 72 at the top. The second spring 62 will quickly rebound upward to its original position. Figure 10 As shown, after the first sealing plug 41 slowly resets, the hydraulic oil inside the second sealing cylinder 6 drives the second sealing plug 61 to reset through negative pressure. The second sealing plug 61 will drive the second conveying plate 66 to move downward to its original position through the second spring 62 and the lifting plate 63. During the downward movement of the second conveying plate 66, because the second conveying plate 66 is inclined, the aluminum rod will roll along the second conveying plate 66 to the conveying rod 21 of the chain conveyor group 2 on the other side of the temperature measuring bracket 3.

[0050] It should be noted that there are multiple limiting rails installed on the inner top wall of the temperature measuring bracket 3. These limiting rails are vertically spaced below the temperature measuring instrument, and the temperature measuring probe is located between the gaps of the limiting rails. This means that the aluminum rod will be blocked by the limiting rails after it moves upward. At this time, the temperature measuring probe of the temperature measuring instrument will measure the temperature of the aluminum rod. When measuring the temperature of a larger diameter aluminum rod, after the second conveyor plate 66 moves upward a short distance and the surface of the aluminum rod has come into contact with the limiting rails, the elastic telescopic rod 65 will contract again under pressure. This prevents the surface of the aluminum rod from being damaged due to the force of contact with the limiting rails. The limiting rails can isolate the aluminum rod and the temperature measuring probe, and the aluminum rod will not damage the temperature measuring probe on the temperature measuring instrument. When the aluminum rod falls onto the first conveyor plate 43, the drop in the aluminum rod will generate gravitational acceleration. The first sealing plug 41 will be subjected to a large force of gravity, which will squeeze the hydraulic oil into the interior of the second sealing cylinder 6, so that the second spring 62 is in a strong compression state. When the aluminum rod rolls onto the second conveyor plate 66, it rolls smoothly without a strong impact force. As a result, the gravity on the second conveyor plate 66 is significantly less than the gravity on the first conveyor plate 43. Therefore, the gravity on the second conveyor plate 66 will compress the elastic telescopic rod 65 and drive the guide rod 73 to move downward a small distance. When the second spring 62 is not limited by the jamming block 72, the instantaneous recovery of the elastic force will drive the aluminum rod to move upward. Multiple aluminum rods are placed one by one on the conveyor rod 21 at equal intervals, with a distance between them. After the aluminum rod in front is measured, it rolls onto the conveyor rod 21 of the chain conveyor group 2 on the other side of the temperature measuring bracket 3, and the aluminum rod behind falls onto the first conveyor plate 43. Therefore, there will be no situation where the aluminum rod in front falls onto the first conveyor plate 43 during the temperature measuring process, which will affect the temperature measurement of the aluminum rod in front.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
