Description

Technical Field

[0001] This utility model relates to the field of aluminum sheet and strip, specifically to an aluminum sheet and strip thickness detection device. Background Technology

[0002] Aluminum sheet and strip, as an important industrial material, are widely used in aerospace, automotive manufacturing, and architectural decoration. In the production process of aluminum sheet and strip, thickness is a key quality indicator that directly affects the performance and usability of the product. Therefore, accurate measurement of aluminum sheet and strip thickness is crucial.

[0003] Traditional methods for inspecting the thickness of aluminum sheets and strips mainly rely on manual measurement and offline inspection. Manual measurement typically uses tools such as micrometers or calipers. While this method is simple, it suffers from low measurement accuracy, poor efficiency, and high labor intensity, making it difficult to meet the needs of modern large-scale production.

[0004] Offline testing requires removing the aluminum sheet and strip from the production line and sending it to the laboratory for measurement. This method is not only time-consuming, but also cannot achieve real-time monitoring, making it difficult to make timely adjustments to the production process.

[0005] Chinese patent CN208721027U discloses an ingot thickness measuring device, including a roller conveyor, an ultrasonic sensor, and a PLC analog input module. The roller conveyor is arranged in two adjacent rows with intervals, and the adjacent ends of the roller conveyor are inclined downwards to the adjacent side.

[0006] Two ultrasonic sensors are used, one above the other between the two roller conveyors. The upper and lower ultrasonic sensors are positioned opposite each other and on the same vertical line. The distance between the two sensors remains constant. The ultrasonic sensors are electrically connected to the PLC analog input module.

[0007] This ingot thickness measuring device can only perform continuous thickness measurement at a single point in the ingot, making it difficult to measure at multiple locations in the width direction. Utility Model Content

[0008] The purpose of this invention is to provide an aluminum sheet / strip thickness detection device that can simultaneously detect the thickness of aluminum sheet / strip at multiple points.

[0009] To achieve the above objectives, this utility model provides an aluminum strip thickness detection device, including a back plate. Multiple sets of frame plates are arranged along the length of the front of the back plate. Each frame plate includes an upper strip plate and a lower strip plate arranged vertically. A lower support wheel assembly is mounted on the upper strip plate, and an upper extrusion wheel assembly capable of elastically resetting is also mounted on the upper strip plate. A gap is formed between the upper extrusion wheel assembly and the lower support wheel assembly to allow the aluminum strip to pass through. The upper end of the upper extrusion wheel assembly extends above the upper strip plate and is fitted with a cover plate. A ranging head is provided on one side of the cover plate, measuring distances towards the upper surface of the upper strip plate. The multiple sets of lower support wheel assemblies mounted on the frame plates are staggered.

[0010] Preferably, the lower strip plate is provided with a first rectangular hole; the lower support wheel assembly includes a first square rod that can be inserted into the first rectangular hole, and a first wheel seat is fixedly connected to the upper end of the first square rod; a support wheel is installed on the first wheel seat, and a first screw is fixedly connected to the lower end of the first square rod, and a flat washer and a first nut are sequentially sleeved on the outside of the first screw.

[0012] Preferably, all four corners of the second square rod are rounded.

[0013] Preferably, the cover plate includes an upper end plate, the bottom surface of which is provided with a square cover that can fit and cover the upper end of the second square rod, the upper end plate is provided with a through hole coaxial with the square cover, and one side of the upper end plate extends outward to form a side protrusion plate, the side protrusion plate is provided with a mounting hole for installing the ranging head.

[0014] Preferably, the ranging head is a laser ranging head or a dial indicator.

[0015] Preferably, the back of the back plate is connected to a telescopic member.

[0016] Preferably, the telescopic component is a cylinder, a hydraulic cylinder, or a linear motor.

[0017] According to the above technical solution, this utility model provides an aluminum strip thickness detection device, including a back plate. Multiple sets of frame plates are arranged along the length of the front of the back plate. Each frame plate includes an upper strip plate and a lower strip plate arranged vertically. A lower support wheel assembly is installed on the upper strip plate. An upper extrusion wheel assembly capable of elastically resetting is also installed on the upper strip plate. A gap is formed between the upper extrusion wheel assembly and the lower support wheel assembly to allow the aluminum strip to pass through. The upper end of the upper extrusion wheel assembly extends above the upper strip plate and is fitted with a cover plate. A ranging head is provided on one side of the cover plate, measuring distances towards the upper surface of the upper strip plate. The multiple sets of lower support wheel assemblies installed on the frame plates are staggered.

[0018] The usage and beneficial effects of this aluminum strip thickness detection device are as follows: A back plate is fixedly installed on one side of the aluminum strip conveyor line, allowing the aluminum strip to pass through the gaps formed between multiple upper extrusion roller sets and lower support roller sets. As the aluminum strip moves, when it passes through the gaps between the upper extrusion roller sets and lower support roller sets, the upper extrusion roller sets are elastically compressed upwards. The upward compression distance varies depending on the thickness of the aluminum strip. By measuring the distance from the upper surface of the upper plate using a distance measuring head, the thickness value of the aluminum strip can be obtained. As the aluminum strip moves, this thickness value forms a thickness curve, which can be used to determine whether the thickness of the aluminum strip meets the standard. Because the lower support roller sets installed on multiple sets of racks are staggered, the corresponding upper extrusion roller sets are also staggered, allowing for the measurement of thickness curves at different positions of the aluminum strip, thereby improving the effectiveness of aluminum strip thickness detection.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0033] See Figure 1-8 The aluminum strip thickness detection device shown includes a back plate 2. Multiple sets of frame plates are arranged along the length of the front of the back plate 2. Each frame plate includes an upper strip plate 4 and a lower strip plate 3 arranged vertically. A lower support wheel assembly is installed on the upper strip plate 4. An upper extrusion wheel assembly capable of elastic reset is also installed on the upper strip plate 4. A gap is formed between the upper extrusion wheel assembly and the lower support wheel assembly to allow the aluminum strip to pass through. The upper end of the upper extrusion wheel assembly extends above the upper strip plate 4 and is fitted with a cover plate. A ranging head 12 is provided on one side of the cover plate to measure distances towards the upper surface of the upper strip plate 4. The multiple sets of lower support wheel assemblies installed on the frame plates are staggered.

[0034] By implementing the above technical solution, when in use, the back plate 2 is fixedly installed on one side of the aluminum strip conveyor line, so that the aluminum strip can pass through the gap formed between multiple upper extrusion rollers and lower support rollers. At this time, as the aluminum strip moves, when the aluminum strip passes through the gap between the upper extrusion rollers and the lower support rollers, the upper extrusion rollers are elastically squeezed upward. Depending on the thickness of the aluminum strip, the distance that the upper extrusion rollers are squeezed upward is also different. The thickness value of the aluminum strip can be obtained by measuring the distance from the measuring head 12 to the upper surface of the upper strip plate 4. As the aluminum strip moves, this thickness value forms a thickness value curve, which can be used to determine whether the thickness of the aluminum strip meets the standard.

[0035] Because the lower support rollers installed on multiple sets of racks are staggered, the corresponding upper extrusion rollers are also staggered, which allows for the measurement of thickness curves at different positions of the aluminum strip, thereby improving the effectiveness of aluminum strip thickness detection.

[0036] In this embodiment, to further provide a lower support wheel assembly and its mounting structure, a first rectangular hole 19 is provided on the lower strip plate 3; the lower support wheel assembly includes a first square rod 21 that can be inserted into the first rectangular hole 19, and a first wheel seat 5 is fixedly connected to the upper end of the first square rod 21; a support wheel 6 is mounted on the first wheel seat 5, and a first screw 15 is fixedly connected to the lower end of the first square rod 21, with a flat washer 17 and a first nut 16 sequentially sleeved on the outside of the first screw 15. During installation, the first square rod 21 is inserted into the first rectangular hole 19 from top to bottom, and then the flat washer 17 and the first nut 16 are sleeved to fix it. The fit between the first square rod 21 and the first rectangular hole 19 can prevent rotation. The rotation axis of the support wheel 6 is perpendicular to the back plate 2, and the support wheel 6 can roll in contact with the bottom surface of the aluminum strip.

[0037] In this embodiment, to further provide an upper extrusion wheel assembly and its mounting structure, a second rectangular hole 20 is provided on the upper strip plate 4; the upper extrusion wheel assembly includes a second square rod 18 that can be inserted into the second rectangular hole 20, and a second wheel seat 7 is fixedly connected to the lower end of the second square rod 18; an extrusion wheel 8 is mounted on the second wheel seat 7, and a second screw 10 is fixedly connected to the upper end of the second square rod 18; a cover plate and a second nut 11 are sequentially sleeved on the outside of the second screw 10; a first spring 13 and a second spring 14 are respectively sleeved on the second square rod 18 below and above the upper strip plate 4. During installation, the second square rod 18 is passed through the first spring 13, the second rectangular hole 20, and the second spring 14 sequentially from bottom to top, and then the cover plate and the second nut 11 are sleeved on and locked in place by the second nut 11, so that the first spring 13 is pressed between the second wheel seat 7 and the upper strip plate 4, and the second spring 14 is pressed between the upper strip plate 4 and the cover plate, so that the second square rod 18 can move vertically and elastically within the second rectangular hole 20. The fit between the second square rod 18 and the second rectangular hole 20 prevents rotation. The rotation axis of the extrusion roller 8 is perpendicular to the back plate 2, and the extrusion roller 8 can roll and make contact with the top surface of the aluminum strip.

[0038] In this embodiment, all four corners of the second square rod 18 are rounded 22. This design reduces the contact area between the second square rod 18 and the second rectangular hole 20, improving the smoothness of movement of the second square rod 18 within the second rectangular hole 20.

[0039] In this embodiment, to further provide a cover plate structure, the cover plate includes an upper end plate 9. The bottom surface of the upper end plate 9 is provided with a square cover 24 that can fit and cover the upper end of the second square rod 18. The upper end plate 9 is provided with a through hole 23 coaxial with the square cover 24. One side of the upper end plate 9 extends outward to form a side protrusion plate, and the side protrusion plate is provided with a mounting hole 25 for installing the ranging head 12. The cover plate can be quickly aligned and installed by the cooperation between the square cover 24 and the second square rod 18. The through hole 23 is set for the second screw 10 to pass through, and the mounting hole 25 is set for the ranging head 12 to be installed. The two can be threaded or fixed by welding.

[0040] In this embodiment, in order to further provide a rangefinder 12, the rangefinder 12 is a laser rangefinder 12 or a dial indicator.

[0041] In this embodiment, the back of the back plate 2 is connected to a telescopic member 1. This arrangement facilitates adjustment of the measurement position, i.e., adjusting the measurement positions of the extrusion roller 8 and the support roller 6 on the aluminum strip, to obtain more measurement data as needed.

[0042] In this embodiment, to further provide a telescopic component 1, the telescopic component 1 is a cylinder, a hydraulic cylinder, or a linear motor.

However, the present invention is not limited to the specific details of the above embodiments.
