Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing, and particularly relates to an on-line sampling device for the surface of a galvanizing line. Background Technique

[0002] During the production process of a galvanizing line, the detection and control of the residues on the surface of galvanized steel plates are important links to ensure product quality and process stability. The traditional method for sampling residues on steel plates is usually to cut the steel plates into sample plates of appropriate specifications, adsorb the surface residues with special filter paper under static conditions, and evaluate the cleaning effect by comparing the weights of the surface residues before and after cleaning. Although this method can accurately measure the amount of residues, it has obvious limitations;

[0003] Firstly, since the galvanizing line is a continuously operating unit, the traditional sampling method needs to stop the machine for sampling, which not only causes the production line to be interrupted, reduces production efficiency, but also increases production costs due to the waste products generated during the shutdown process. In the highly competitive modern manufacturing industry, this way of sampling during shutdown obviously cannot meet the requirements of high-efficiency and continuous production. Secondly, the traditional sampling method can only be carried out under static conditions and cannot truly reflect the dynamic changes of the residues on the surface of the steel plate during the continuous operation of the galvanizing line. This may lead to deviations in the evaluation of product quality and process stability, thereby affecting the overall quality of the product. Therefore, we propose an on-line sampling device for the surface of a galvanizing line to solve the above problems. Content of the Utility Model

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides an on-line sampling device for the surface of a galvanizing line, which has the following beneficial effects:

[0018] In the utility model, the device is fixed at a suitable position on the galvanizing line.

The time recorded by the encoder is multiplied by the speed of the strip steel to obtain the distance of contact between the walking wheel and the strip steel. During the contact between the walking wheel and the strip steel, the filter paper will collect the residues on the surface of the strip steel. After the sampling is completed, the filter paper is taken off, and the collected residues are further analyzed and evaluated. The on-line sampling device for the surface of the galvanizing line can realize the real-time on-line sampling of the residues on the surface of the galvanizing line, and provide accurate data support for the subsequent residue analysis by accurately calculating the sampling time and area.

Two rotating shafts 2 are rotatably connected between the inner walls on both sides of the first U-shaped plate 1. Two walking wheels 3 are fixedly connected to the rotating shafts 2. A pressure sensor 4 is fixedly connected to the bottom inner wall of the first U-shaped plate 1. A gear 5 is fixedly connected to one of the two rotating shafts 2. The gear 5 cooperates with the pressure sensor 4. A filter paper 6 is in movable contact with the bottom inner wall of the first U-shaped plate 1. The bottom of the first U-shaped plate 1 is fixedly connected to a second U-shaped plate 7. A battery box 8, an encoder 9 and a switch 10 are fixedly connected to the top inner wall of the second U-shaped plate 7. The device is fixed at a suitable position on the galvanizing line through the first U-shaped plate 1 and the second U-shaped plate 7 to ensure that the walking wheels 3 can contact the surface of the strip steel. When the strip steel passes through the device, the walking wheels 3 contact the surface of the strip steel and generate pressure. After the pressure sensor 4 detects the pressure, the encoder 9 is started to record time through the circuit system. The encoder 9 continuously records time until the strip steel passes through the device and the walking wheels 3 are separated from the strip steel and the pressure disappears. After the pressure disappears, the encoder 9 stops recording time and saves the time data of this period. The speed of the strip steel is directly obtained through computer display. The time recorded by the encoder 9 is multiplied by the speed of the strip steel to obtain the distance of contact between the walking wheels 3 and the strip steel. During the contact between the walking wheels 3 and the strip steel, the filter paper 6 will collect the residues on the surface of the strip steel. After the sampling is completed, the filter paper 6 is taken off and the collected residues are further analyzed and evaluated. This on-line surface sampling device for the galvanizing line can realize real-time on-line sampling of the residues on the surface of the galvanizing line, and provide accurate data support for subsequent residue analysis by accurately calculating the sampling time and area.

[0027] In some embodiments, the battery box 8, the switch 10, the encoder 9 and the pressure sensor 4 are electrically connected through transmission wires. Two mounting holes 11 are opened on the top inner wall of the second U-shaped plate 7. The setting of the second U-shaped plate 7 plays a supporting role.

[0028] In some embodiments, four cavities 12 are opened on the first U-shaped plate 1. A retaining pin 13 is provided on the cavity 12. A limiting ring 14 is fixedly connected to the retaining pin 13. The setting of the limiting ring 14 plays a limiting role.

[0029] In some embodiments, a spring 15 is welded between one side of the limiting ring 14 and one side inner wall of the corresponding cavity 12. The spring 15 is movably sleeved on the corresponding retaining pin 13. The setting of the spring 15 plays a resetting role.

[0030] In some embodiments, the end of the retaining pin 13 extends outside the first U-shaped plate 1 and is welded with a pulling block 16. A guiding hole is opened on one side inner wall of the cavity 12. The guiding hole is slidably connected to the corresponding retaining pin 13. The setting of the pulling block 16 plays a connecting role.

[0031] In some embodiments, four mounting blocks 17 are fixedly connected to the bottom of the filter paper 6. A clamping groove 18 is formed on one side of the mounting block 17, and the clamping groove 18 is clamped with the corresponding clamping pin 13. The setting of the mounting block 17 plays a role in connection.

[0032] In some embodiments, a rectangular hole 19 is formed in the inner wall of the top of the cavity 12. The inner wall of the rectangular hole 19 is in movable contact with the corresponding mounting block 17. The setting of the rectangular hole 19 plays a role in limiting.

[0033] Working principle or structural principle: During use, it is fixed at a suitable position on the galvanizing line through the first U-shaped plate 1 and the second U-shaped plate 7 to ensure that the running wheel 3 can contact the surface of the strip steel. When the strip steel passes through the device, the running wheel 3 contacts the surface of the strip steel and generates pressure. After the pressure sensor 4 detects the pressure, the encoder 9 is started to record through the circuit system. The encoder 9 continuously records the time until the strip steel passes through the device and the running wheel 3 is separated from the strip steel and the pressure disappears. After the pressure disappears, the encoder 9 stops recording the time and saves the time data of this period. The speed of the strip steel is directly obtained through the computer display. The time recorded by the encoder 9 is multiplied by the speed of the strip steel to obtain the distance of contact between the running wheel 3 and the strip steel. During the contact between the running wheel 3 and the strip steel, the filter paper 6 will collect the residues on the surface of the strip steel. After the sampling is completed, the filter paper 6 is removed, and the collected residues are further analyzed and evaluated. This on-line sampling device for the surface of the galvanizing line can realize on-line real-time sampling of the residues on the surface of the galvanizing line, and provide accurate data support for the subsequent residue analysis by accurately calculating the sampling time and area. When removing the filter paper 6, pull the pull block 16. The pull block 16 drives the corresponding clamping pin 13 to move. The clamping pin 13 drives the corresponding limiting ring 14 to move and compress the spring 15, so that the clamping pin 13 is separated from the corresponding clamping groove 18. Then move the filter paper 6 to remove it.
