Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum foil corrosion production, and more specifically, to a tension detection device for a corrosion production line. Background Technology
[0002] In the production of etched aluminum foil, reliable detection by tension sensors is a key factor in ensuring product quality and production continuity.
[0003] Because aluminum foil undergoes chemical etching and cleaning processes during corrosion treatment, the production environment is constantly exposed to acid fumes and chemical splashes, leading to the formation of chemical crystals around the production line frames. These crystals adhere to the strain gauge gaps of the tension sensor, hindering strain gauge deformation feedback and causing distortion or failure of the tension detection signal. Furthermore, maintenance personnel must periodically flush the frames with high-pressure water to remove any remaining crystals. The splashed water generated during this process can easily seep into the sensor, causing corrosion and short circuits in electronic components and rust on metal parts.
[0004] Existing tension sensor detection devices mostly employ conventional installation structures, which are insufficient to effectively resist the intrusion of crystals and liquid splashes. This results in a high sensor failure rate, and frequent replacements not only increase production costs but also easily lead to process abnormalities such as strip breakage and wrinkling caused by uncontrolled aluminum foil tension. Currently, the industry urgently needs a sensor protection device that can adapt to corrosive production environments, effectively preventing crystals from clogging the tension sensor and causing detection distortion or even failure, thereby improving the environmental adaptability and service life of the tension sensor. Utility Model Content
[0005] The purpose of this invention is to overcome the problem in the prior art where crystal blockage of tension sensors leads to detection distortion or even failure, and to provide a tension detection device for corrosion production lines, thereby improving the environmental adaptability and service life of tension sensors.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A tension detection device for a corrosion production line is provided, including a tension sensor, an oil box, and a cover. The tension sensor is installed on the bottom surface of the cavity of the oil box, and the cover is placed on the oil box. The height of the side wall of the oil box is less than the height of the top of the tension sensor. The top surface inside the cavity of the cover is fixedly connected to the top surface of the tension sensor. The oil box is filled with transformer oil, and the tension sensor is partially immersed in the transformer oil.
[0008] In the operation of the above scheme, the height of the side wall of the oil box is lower than the height of the top of the tension sensor, so that the cover is rigidly connected to the top of the sensor only through the internal top surface, forming a suspended internal cavity. When the tension of the aluminum foil acts on the cover, the tension is directly transmitted to the top of the sensor, driving the tension sensor to produce vertical displacement in the oil box. Due to the height limitation of the side wall of the oil box, the sensor can jump up and down freely within the preset height difference range (1mm to 2mm). The cover will not contact the side wall of the oil box, ensuring that the tension sensor is only subjected to tension and not to the support force from the side wall of the oil box, thereby eliminating the interference of the mechanical support of the side wall on the tension detection. During this process, the variable pressure oil in the oil box forms a dynamic coating layer. When the sensor is displaced, the oil buffers the mechanical vibration through viscous resistance. At the same time, the surface tension of the oil film is used to adhere to the surface of the key parts of the sensor, continuously covering the gap of the strain gauge and preventing the intrusion of external crystals. The incompressible properties of the oil ensure that the tension is transmitted to the strain gauge of the sensor without damage through the liquid medium, so that the detection signal only reflects the actual tension value of the aluminum foil. This suspended oil seal structure maintains the sensor's freedom of movement while providing dual protection against crystallization blockage and liquid corrosion through the physical isolation of the oil. It effectively prevents crystals from blocking the tension sensor, thus avoiding detection distortion or even failure, and improves the environmental adaptability and service life of the tension sensor.
[0009] Furthermore, the height of the transformer oil level is less than or equal to the height of the side wall of the oil box and greater than two-thirds of the height of the tension sensor. The transformer oil only needs to completely immerse the key parts of the sealing tension sensor. Limiting the maximum height of the transformer oil is to prevent it from overflowing between the side wall of the oil box and the side wall of the box cover due to excessively high transformer oil level during vibration, which would affect the detection under the viscous flow and friction of the oil.
[0010] Furthermore, there is a gap between the oil box and the box cover during installation; the gap is designed to prevent the tension sensor from distorting due to friction between the side wall of the box cover and the side wall of the oil box.
[0011] Furthermore, it also includes an oil baffle ring, with the tension sensor located inside the oil baffle ring, which is situated within the gap between the oil box and the box cover. The oil baffle ring is installed on the top surface inside the cavity of the box cover or on the top of the side wall of the oil box. The oil baffle is designed to block the transformer oil and prevent it from leaking into the gap. The oil baffle ring can be fixed to the top surface inside the cavity of the box cover; this design allows for a longer oil baffle and better oil-blocking effect. Alternatively, the oil baffle ring can be installed on the top of the side wall of the oil box; while this design limits the length of the oil baffle, it is easier to manufacture.
[0012] Furthermore, the oil baffle ring is inclined. When the oil baffle ring is fixed to the top surface inside the cavity of the lid, one end of the oil baffle ring is close to the top of the side wall of the oil box, and the other end of the oil baffle ring is close to the top of the tension detector; or when the oil baffle ring is fixed to the top of the side wall of the oil box, the top end of the oil baffle ring is inclined towards the center of the oil box. The inclined oil baffle can improve the oil baffle effect and also prevent the oil baffle from being too long and interfering with the oil box or lid.
[0013] Furthermore, the cover is provided with mounting holes, and the tension sensor has a threaded hole on its top. The mounting holes align with the threaded holes, and the cover is threadedly connected to the tension sensor. The cover and the tension sensor are connected by a thread, making installation simple.
[0014] Furthermore, an observation hole for observing the oil level is provided on the side of the top surface of the cover away from the mounting hole; the observation hole does not abut against the top surface of the tension sensor, and the setting of the observation hole makes it convenient for workers to observe whether the level of transformer oil in the oil box meets the standard, so as to make timely adjustments when the level of transformer oil does not meet the standard.
[0015] Furthermore, the bottom surface of the oil box cavity is provided with a mounting boss, and the tension sensor is threadedly connected to the mounting boss; the mounting boss is used to install the tension sensor, and the threaded connection is adopted. The screw needs to have a certain depth to achieve tightening and fixing, so the mounting boss is provided to increase the depth of the threaded connection.
[0016] Furthermore, a threading tube is provided inside the oil box, and a through hole is provided on the bottom surface of the oil box. One end of the threading tube is connected to the through hole, and the other end extends to the top of the oil box. The tension sensor is provided with a connecting wire, which enters from the top of the threading tube, passes through the threading tube, and exits from the through hole to the outside of the oil box. The tension sensor needs to be electrically connected to the outside through the connecting wire. The threading tube can prevent oil leakage and also lead the connecting wire out of the oil box.
[0017] Furthermore, it also includes a bearing housing, which is mounted on the top surface of the box cover. The bearing housing is used to mount aluminum foil to realize the basic function of the tension sensor in detecting tension.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The tension sensor is installed on the bottom surface of the cavity of the oil box. The cover is placed on the oil box, and the height of the side wall of the oil box is less than the height of the top of the tension sensor. The top surface inside the cavity of the cover is fixedly connected to the top surface of the tension sensor. The oil box is filled with transformer oil, and the tension sensor is partially immersed in the transformer oil. The physical isolation of the oil achieves dual protection against crystallization blockage and liquid corrosion, which can effectively prevent crystals from blocking the tension sensor and causing its detection distortion or even failure, thus improving the environmental adaptability and service life of the tension sensor.
[0020] 2. One end of the wire guide tube is fixedly connected to the bottom surface of the oil box, and the other end extends to the top of the oil box, leading the connecting wire out of the oil box, which facilitates the connection of the connecting wire to the outside while preventing oil leakage.

[0029] Example 1
[0030] This embodiment is a first embodiment of a tension detection device for a corrosion production line, such as... Figure 1 As shown, the device includes a tension sensor 100, an oil box 200, and a cover 300. The tension sensor 100 is mounted on the bottom surface of the cavity of the oil box 200. The cover 300 is placed on the oil box 200. The height of the side wall of the oil box 200 is less than the height of the top of the tension sensor 100. The top surface inside the cavity of the cover 300 is fixedly connected to the top surface of the tension sensor 100. The oil box 200 is filled with transformer oil 400, and the tension sensor 100 is partially immersed in the transformer oil 400.
[0031] Specifically, the height of the transformer oil 400 is less than or equal to the height of the side wall of the oil box 200 and greater than two-thirds of the height of the tension sensor 100. The transformer oil 400 only needs to completely immerse the key parts of the tension sensor 100. Limiting the maximum height of the transformer oil 400 is to prevent it from overflowing between the side wall of the oil box 200 and the side wall of the box cover 300 due to excessively high level during vibration, which would affect the detection under the viscous flow and friction of the oil.
[0032] Specifically, there is a gap between the oil box 200 and the cover 300 during installation; the gap is designed to prevent friction between the cover 300 and the oil box 200 from causing distortion in the tension sensor detection.
[0033] The working principle of the tension detection device for a corrosion production line in this embodiment is as follows:
[0034] Before the test begins, transformer oil 400 is injected into the oil box 200, and the cover 300 is installed. Then, the entire device is installed on the aluminum foil etching production line. When the tension of the aluminum foil acts on the cover 300, the tension is directly transmitted to the top of the sensor, driving the tension sensor 100 to produce a vertical displacement within the oil box 200. Due to the height limitation of the side wall of the oil box 200, and the gap between the outer surface of the side wall of the oil box 200 and the inner surface of the side wall of the cover 300 during installation, the sensor can move freely up and down within a preset height difference range without contacting the side wall of the oil box 200. This ensures that the tension sensor is only subjected to tension and not to the support force and friction force from the side wall of the oil box 200, thereby eliminating the interference of the mechanical support of the side wall on the tension detection. During this process, the transformer oil 400 in the oil box 200 forms a dynamic coating layer on the key parts of the tension sensor 100 and prevents the intrusion of external crystals. The incompressible properties of the oil ensure that the tension is transmitted to the strain gauge of the sensor without damage through the liquid medium, so that the detection signal only reflects the actual tension value of the aluminum foil.
[0035] The beneficial effects of this embodiment are: the physical isolation of the oil achieves dual protection against crystallization blockage and liquid corrosion, which can effectively prevent crystals from blocking the tension sensor and causing its detection distortion or even failure, thereby improving the environmental adaptability and service life of the tension sensor.
[0036] Example 2
[0037] This embodiment is a second embodiment of a tension detection device for a corrosion production line, such as... Figures 2 to 5 As shown, the difference from Embodiment 1 is as follows:
[0038] Specifically, it also includes an oil baffle ring 500, with the tension sensor 100 located inside the oil baffle ring 500. The oil baffle ring 500 is located in the gap between the oil box 200 and the cover 300. The oil baffle ring 500 is installed on the top surface inside the cavity of the cover 300 or on the top of the side wall of the oil box 200. The oil baffle is designed to block the transformer oil 400 from leaking into the gap. The oil baffle ring 500 can be fixed to the top surface inside the cavity of the cover 300. This design allows for a longer oil baffle and better oil blocking effect. The oil baffle ring 500 can also be installed on the top of the side wall of the oil box 200. Although this design limits the length of the oil baffle, it is easier to manufacture.
[0039] Specifically, the oil baffle ring 500 is set at an angle. When the oil baffle ring 500 is fixed to the top surface of the cavity of the cover 300, one end of the oil baffle ring 500 is close to the top of the side wall of the oil box 200, and the other end of the oil baffle ring 500 is close to the top of the tension detection; or when the oil baffle ring 500 is fixed to the top of the side wall of the oil box 200, the top of the oil baffle ring 500 is tilted towards the center of the oil box 200. The angled oil baffle can improve the oil baffle effect and also prevent the oil baffle from being too long and interfering with the oil box 200 or the cover 300.
[0040] The working principle of the tension detection device for a corrosion production line in this embodiment is as follows:
[0041] During the operation of the tension sensor 100, the transformer oil 400 will experience surface fluctuations due to slight vibrations. When the fluctuations are too large, the oil baffle ring 500 can block the transformer oil 400 droplets with excessive fluctuations, preventing them from leaking out from the gaps.
[0042] The beneficial effect of this embodiment is that by setting the oil baffle ring 500, leakage of transformer oil 400 is effectively prevented.
[0043] Example 3
[0044] This embodiment is a third embodiment of a tension detection device for a corrosion production line, such as... Figures 2 to 5 As shown, the difference from Embodiment 1 is as follows:
[0045] Specifically, the cover 300 is provided with a mounting hole 310, and the tension sensor 100 has a threaded hole on its top. The mounting hole 310 mates with the threaded hole, and the cover 300 is threadedly connected to the tension sensor 100. The cover 300 and the tension sensor 100 are connected by a thread, which makes installation simple.
[0046] Specifically, an observation hole 320 for observing the oil level is provided on the side of the top surface of the cover 300 away from the mounting hole 310. The observation hole 320 does not abut against the top surface of the tension sensor 100. The setting of the observation hole 320 makes it convenient for workers to observe whether the level of the transformer oil 400 in the oil box 200 meets the standard, so that timely adjustment can be made when the level of the transformer oil 400 does not meet the standard.
[0047] Specifically, the bottom surface of the oil box 200 cavity is provided with a mounting boss 210, and the tension sensor 100 is threadedly connected to the mounting boss 210. The mounting boss 210 is used to install the tension sensor 100. The threaded connection is used. The screw needs to have a certain depth to tighten and fix it. Therefore, the mounting boss 210 is provided to increase the depth of the threaded connection.
[0048] Specifically, a threading tube 220 is provided inside the oil box 200. A perforation is provided on the bottom surface of the oil box 200. One end of the threading tube 220 is connected to the perforation, and the other end extends to the top of the oil box 200. The tension sensor 100 is provided with a connecting wire 110. The connecting wire 110 passes through the top of the threading tube 220 and exits through the perforation to the outside of the oil box 200. The tension sensor 100 needs to be electrically connected to the outside through the connecting wire 110. The threading tube 220 can prevent oil leakage and also lead the connecting wire 110 out of the oil box 200.
[0049] Specifically, it also includes a bearing housing 600, which is mounted on the top surface of the cover 300. The bearing housing 600 is used to mount aluminum foil to realize the basic function of the tension sensor in detecting tension.
[0050] The working principle of the tension detection device for a corrosion production line in this embodiment is as follows:
[0051] After a period of use, the transformer oil 400 in the oil box 200 may evaporate due to environmental factors, and the level of transformer oil 400 will drop. At this time, observe the liquid level through the observation hole 320. After confirming that the transformer oil 400 is insufficient, remove the threaded connection of the mounting hole 310, remove the box cover 300, and add transformer oil 400 into the oil box 200. The connecting wire 110 connects the tension sensor 100 to the external terminal through the wire threading tube 220 and the through hole to realize the transmission of detection signal.
[0052] The beneficial effects of this embodiment are: the setting of the observation hole 320 makes it easy for workers to observe whether the level of transformer oil 400 in oil box 200 meets the standard, so that it can be adjusted in time when the level of transformer oil 400 does not meet the standard.
[0053] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
