Description

Technical Field

[0001] The embodiments of this utility model relate to the field of sampling device technology, specifically to an automatic sampling device for measuring the reflectivity of a continuous strip plate surface. Background Technology

[0002] In continuous annealing mill production, the cleaning effect of the degreasing and cleaning section affects the quality of cold-rolled strip steel. Currently, the industry assesses the cleaning effect by measuring the reflectivity of the strip surface, with measurements taken every 6 hours after a machine shutdown. During operation, 3M tape is applied to the measurement location, and after removal, a reflectometer is used to measure the tape's reflectivity data to determine whether the cleaning meets the standards.

[0003] However, this measurement method has drawbacks: frequent downtime reduces production efficiency, decreases capacity, and increases costs; adhesive sampling is labor-intensive, increases labor intensity, and poses safety risks when operated on the production line. With the development of industrial automation, there is an urgent need for new devices to solve these problems, improve efficiency, and reduce labor intensity and safety risks. Utility Model Content

[0006] Mobile seat, mobile settings;

[0007] The sampling component is movable relative to the movable seat. The sampling component has a mounting part on which an adhesive tape is mounted. The sampling component is configured to move so that the adhesive tape can move closer to different positions of the steel belt after it is moved.

[0008] A pusher block is slidably disposed on the sampling element. The pusher block is configured to slide and push the tape to adhere to the steel strip.

[0009] For example, at least one embodiment of this utility model provides an automatic sampling device for measuring the reflectivity of a continuous strip plate surface, wherein the sampling element includes:

[0010] The mounting block is movable relative to the movable seat, and the push block is slidably mounted on the mounting block;

[0012] The second sliding block is slidably disposed on the mounting block. The first and second sliding blocks are configured to slide closer to or further away from each other. The mounting part is located on the first sliding block. The second sliding block has a clamping part for clamping the end of the tape. When the first and second sliding blocks are configured to move further away from each other, the tape can be stretched. The push block is located between the first and second sliding blocks. When the push block is configured to slide, it can adhere the stretched tape to the steel belt.

[0013] For example, at least one embodiment of this utility model provides an automatic sampling device for measuring the reflectivity of a continuous strip plate surface, wherein the second sliding block has a first sliding groove, and the clamping part includes:

[0014] The pressure block is slidably disposed in the first slide groove and forms a snap-fit ​​gap with the side wall of the first slide groove, and the end of the tape is used to snap into the snap-fit ​​gap;

[0015] The first elastic element has one end disposed on the inner wall of the first groove and the other end disposed on the pressure block. The first elastic element is used to elastically push the pressure block so that the tape can be clamped within the snap-fit ​​gap.

[0019] The second link is hinged at one end to the other end of the rotating rod and at the other end to the second sliding block. The rotating rod is configured such that when it rotates, the first and second links can drive the first and second sliding blocks to move closer and further apart.

[0020] For example, at least one embodiment of this utility model provides an automatic sampling device for measuring the reflectivity of a continuous strip plate surface. The mounting block has a guide groove, and a push block is slidably disposed within the guide groove. After the push block slides out of the guide groove, it is used to approach the tape.

After the push block is configured to slide out of the guide groove, the second elastic element is configured to push the extension block so that the extension block slides out of the second slide groove. After the first sliding block and the second sliding block are configured to move closer to each other, they can drive the extension block to slide into the second slide groove.

[0027] The first swing arm has one end swaying and mounted on the movable seat;

[0028] The second swing arm is oscillating at one end on the other end of the first swing arm, and the mounting block is located on the other end of the second swing arm. After the first and second swing arms swing, they are used to drive the tape to different positions on the steel belt.

[0029] For example, at least one embodiment of this utility model provides an automatic sampling device for measuring the reflectivity of a continuous strip plate surface, wherein the movable base includes:

[0030] A base, used for setting up on the ground;

Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0042] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0043] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] like Figures 1-4As shown, this invention illustrates an automatic sampling device for measuring the reflectivity of a continuous strip plate surface according to one embodiment. A movable base 1 is movably mounted on the ground, and a sampling component 2 is movably mounted on the movable base 1. The sampling component 2 has a mounting portion 21 on which adhesive tape is mounted. The mounting portion 21 is a bracket structure mounted on the sampling component 2, and the bracket has a shaft for mounting the adhesive tape roll. The adhesive tape roll is sleeved on the shaft, and the adhesive surface of the tape extends from the roll, facing the steel strip.

[0048] Push block 3 is slidably mounted on sampling piece 2. After sliding, push block 3 pushes the tape to adhere to the steel belt. After sampling piece 2 moves away from the steel belt, the tape can be removed from the steel belt. The tape can then be inspected to determine if the steel belt is clean. A longitudinal guide rail is provided on sampling piece 2. Push block 3 is connected to the longitudinal guide rail via a sliding fit, which can be a linear bearing. Push block 3 is driven to slide on sampling piece 2 by a drive device, which can be a cylinder. The cylinder body is fixed to sampling piece 2, and the piston rod is connected to push block 3. The extension and retraction of the piston rod drives push block 3 to slide along the longitudinal guide rail. When push block 3 slides, its front end contacts the tape and applies a pushing force, causing the tape to adhere tightly to the surface of the steel belt, completing the adhesion process.

[0049] The automatic sampling process for measuring the reflectivity of a plate surface is achieved through the cooperation of the movable seat 1, the sampling component 2, and the pusher block 3. The movable seat 1 can move on the ground and adjust the position of the device in the production line direction according to production needs, enabling the device to reach different widths of the steel strip for sampling. The sampling component 2 moves on the movable seat 1 and can apply adhesive tape during the steel strip production process. During the application process, it moves with the steel strip to ensure that the tape is adhered to the steel strip. After application, the tape is randomly removed. During removal, the sampling component 2 also moves along the steel strip conveying direction with the steel strip. The mounting part 21 is used to install the adhesive tape, allowing the tape to be placed on the sampling component 2, facilitating the pusher block 3 to push the tape for application. The pusher block 3 is slidably mounted on the sampling component 2 and is driven to slide by a drive device, enabling the tape to be adhered to the steel strip. This avoids the tedious operation of manual application sampling. When removing the tape, simply move the sampling component 2 away from the steel strip to remove the tape.

[0050] Compared with existing technologies, this device eliminates the need for manual shutdown for sampling. Furthermore, the sampling component 2 moves synchronously with the steel strip along its conveying direction, reducing downtime, improving production efficiency, avoiding the impact of frequent shutdowns on capacity, and lowering production costs. Simultaneously, it completely replaces manual pasting sampling, reducing manpower input, lowering worker fatigue, and eliminating safety risks for workers operating on the production line. The adjustable movement of the movable seat 1 and sampling component 2 allows the device to automatically sample different positions on the steel strip, improving sampling accuracy and comprehensiveness, ensuring accurate assessment of the strip cleaning effect, and thus contributing to improved quality of cold-rolled strip steel.

[0051] like Figure 1 As shown, the sampling component 2 includes a mounting block 22, a first sliding block 23, and a second sliding block 24. The sliding directions of the first sliding block 23 and the second sliding block 24 are opposite. The first sliding block 23 has a mounting part 21, which has a shaft structure. A roll of adhesive tape is sleeved on the shaft, and the tape is led out from the tape roll, with its end extending to the position of the second sliding block 24. The top surface of the second sliding block 24 has a clamping part 241, which is provided corresponding to the tape lead-out end and is used to fix the tape end.

[0052] Specifically, the second sliding block 24 has a first groove 242, and the pressure block 2411 of the clamping part 241 is connected to the inner wall of the first groove 242 through the first elastic member 2412. The pressure block 2411 and the first groove 242 form a snap-fit ​​gap 2413. After the end of the tape is inserted into the snap-fit ​​gap 2413, the elastic force of the first elastic member 2412 causes the pressure block 2411 to press the tape tightly, thereby fixing the end. The first sliding block 23 and the second sliding block 24 move away from each other and stretch the tape. The push block 3 is located between the first sliding block 23 and the second sliding block 24. When the tape is stretched to a taut state, the push block 3 slides, and its bottom surface contacts the tape and applies a pushing force to stick the tape to the steel belt.

[0053] The tape is stretched by the reverse sliding of the first sliding block 23 and the second sliding block 24, ensuring that the tape is taut before application and avoiding problems such as poor adhesion or wrinkles caused by tape slack. The clamping part 241 uses the elastic force of the first elastic element 2412 to fix the tape end, eliminating the need for manual fixing, simplifying the operation process, effectively solving the problem of inconsistent tape application during manual sampling, and further improving the automation level and sampling efficiency of the device.

[0054] like Figure 1As shown, the first groove 242 on the second sliding block 24 is arranged along the thickness direction of the tape. The pressure block 2411 is generally rectangular and slides against the inner wall of the first groove 242, thus limiting the sliding direction of the pressure block 2411. One end of the first elastic member 2412 is fixedly connected to the inner wall of the first groove 242 near the end of the tape, and the other end is fixedly connected to the corresponding end face of the pressure block 2411. When the end of the tape is inserted into the snap-fit ​​gap 2413, the first elastic member 2412 extends, and under the action of the spring restoring force, the pressure block 2411 applies a clamping force to the end of the tape, so that the tape is clamped in the snap-fit ​​gap 2413.

[0055] The automatic clamping function of the tape end is realized through the cooperation of the first elastic element 2412 and the pressure block 2411. The elastic pushing action of the first elastic element 2412 can adapt to tapes of different thicknesses, ensuring stable clamping of tape ends of various specifications and avoiding insecure clamping due to differences in tape thickness.

[0056] like Figure 1 As shown, the second end of the rotating rod 4 corresponds to one end, and the third end corresponds to the other end. The first end of the rotating rod 4 is hinged to the middle of the mounting block 22 via a rotating shaft 232. The second and third ends are located on both sides of the first end and are linearly distributed with the first end. One end of the first connecting rod 5 is hinged to the second end of the rotating rod 4 via a pin, and the other end is hinged to the side of the first sliding block 23 via a pin. One end of the second connecting rod 6 is hinged to the third end of the rotating rod 4 via a pin, and the other end is hinged to the side of the second sliding block 24 via a pin. The rotation of the rotating rod 4 is controlled by a rotary drive mechanism mounted on the mounting block 22. This mechanism includes a motor, a reducer, and a gear transmission assembly. The output shaft of the motor is connected to the gear via the reducer. A gear ring meshes with the gear on the rotating rod 4. After the motor rotates, the speed is reduced and the torque is increased by the reducer. The meshing of the gear and the gear ring drives the rotating rod 4 to rotate around the rotating shaft 232. When the rotating rod 4 rotates, the first connecting rod 5 and the second connecting rod 6 move with the end of the rotating rod 4, pulling the first sliding block 23 and the second sliding block 24 to slide in opposite directions, thereby realizing the tape stretching action.

[0057] The rotational motion of the rotating rod 4, the first connecting rod 5, and the second connecting rod 6 are converted into the linear motion of the first sliding block 23 and the second sliding block 24 through a linkage transmission mechanism, thereby achieving automatic stretching of the tape. This transmission method has a compact structure, high transmission efficiency, and can stably transmit power, ensuring the synchronicity and symmetry of the movement of the first sliding block 23 and the second sliding block 24. This ensures that the tape is subjected to uniform force during stretching, avoiding tape deformation or tearing caused by uneven force.

[0058] like Figure 2As shown, the mounting block 22 has a guide groove 221 extending along the adhesive tape pasting direction (steel strip thickness direction). The push block 3 is rectangular, and its two side walls slide in fit with the inner wall of the guide groove 221. The push rod 7 is set in the guide groove 221, and the push rod 7 has an external thread. The mounting block 22 has a threaded hole, and the push rod 7 is screwed into the threaded hole through the threaded fit. A bearing seat is set at the center of the bottom of the push block 3, and the push rod 7 is rotatably connected to the bearing seat through the bearing. When the push rod 7 is rotated, due to the threaded transmission, the push rod 7 moves closer to or away from the steel strip along the direction of the guide groove 221, causing the push block 3 to slide synchronously in the guide groove 221. When the push block 3 slides out of the guide groove 221, the push block 3 contacts the surface of the adhesive tape, and continuing to rotate the push rod 7 can push the adhesive tape to be pasted onto the steel strip.

[0059] The movement control of push block 3 is achieved through the threaded transmission between push rod 7 and push block 3. Compared with the traditional cylinder or hydraulic cylinder drive method, the threaded transmission has higher positioning accuracy and can accurately control the contact pressure and pasting stroke of the tape and steel belt. This avoids damage to the tape due to excessive pressure or failure to paste onto the steel belt due to insufficient pressure, or excessive pasting force that affects the conveying of the steel belt.

[0060] like Figure 2 As shown, the push block 3 has second grooves 31 at both ends along its length. The extension block 8 is cuboid in shape, and its size is adapted to the second grooves 31, allowing it to slide along the length of the second grooves 31. The second elastic element 9 is a spring, with one end fixedly connected to the inner wall of the second groove 31 away from the opening 311, and the other end fixedly connected to the corresponding end face of the extension block 8. When the push block 3 slides out of the guide groove 221 and approaches the tape, as the push block 3 moves further, the extension block 8 is no longer limited by the guide groove 221. The elastic force of the second elastic element 9 pushes the extension block 8 to slide out from the opening 311 of the second groove 31, so that the extension block 8 and the push block 3 jointly abut against the tape, increasing the contact area with the tape.

[0061] Sliding extension blocks 8 and second elastic elements 9 are provided at both ends of the push block 3. During the tape application process, the elastic force of the second elastic element 9 enables the extension blocks 8 to extend adaptively, adjusting the contact area with the tape. Compared to a single push block 3, the combined structure of the push block 3 and the extension blocks 8 increases the force distribution range on the tape and makes the force on the tape more uniform during application. This structure eliminates the need for complex sensing and control systems, achieving its function solely through a mechanical elastic structure, thus reducing the technical complexity and manufacturing cost of the device.

[0062] The opening 311 of the second groove 31 is designed to cooperate with the structure of the extension block 8, ensuring that the extension block 8 can extend stably and form a continuous contact surface with the push block 3, synchronously contacting the tape and avoiding uneven force on the tape caused by the extension block 8's offset position. The structure of the extension block 8 extending and being on the same plane as the push block 3 allows both to apply pressure simultaneously and evenly when applying the tape, reducing tape adhesion defects caused by uneven pressure concentration or dispersion.

[0063] like Figure 3 As shown, one end of the first swing arm 10 is sleeved on the vertical rotating shaft 232 via a bearing, forming a swingable connection structure. A swing drive motor is installed on the base 101, and the motor output shaft is connected to the vertical rotating shaft 232 via a synchronous belt transmission mechanism. The rotation of the motor drives the first swing arm 10 to swing around the vertical rotating shaft 232. One end of the second swing arm 11 is sleeved on the horizontal rotating shaft 232 via a bearing, similarly forming a swingable connection structure. Another swing drive motor is installed on the first swing arm 10, and this motor drives the second swing arm 11 to swing around the horizontal rotating shaft 232 via a gear transmission mechanism. The mounting block 22 is fixedly installed at the other end of the second swing arm 11. The mounting block 22 of the sampling component 2, the first sliding block 23, and the second sliding block 24 are installed on the mounting block 22. When the first swing arm 10 swings, it drives the second swing arm 11 and the mounting block 22 to swing vertically; when the second swing arm 11 swings, it drives the mounting block 22 to swing in the direction of the steel strip production line.

[0064] The two-stage swing structure of the first swing arm 10 and the second swing arm 11 enables the position adjustment of the sampling component 2, allowing it to move synchronously with the steel belt and adhere the tape to it. The swing drive motor, in conjunction with the transmission mechanism, controls the swing angle of the swing arms and allows for precise adjustment of the tape's sampling position on the steel belt according to production needs. The layered swing design of the first swing arm 10 and the second swing arm 11 provides better spatial flexibility when adjusting the sampling position. Even in situations with limited space on the production line or interference from other equipment, the tape can be smoothly moved to the target position, enhancing the device's environmental adaptability.

[0065] like Figure 3 As shown, the base 101 is flat, with a slide rail on its top along the width of the steel strip. A slider matching the slide rail is mounted on the bottom of the sliding seat 102, embedding itself within the slide rail and sliding along it. A translation drive motor is installed at one end of the base 101, with its output shaft connected to a lead screw. The lead screw is positioned along the slide rail and fixedly connected to the sliding seat 102 via a lead screw nut. When the translation drive motor rotates, the lead screw rotates accordingly, causing the sliding seat 102 to move linearly along the slide rail of the base 101 via the lead screw nut. After movement, the adhesive tape can be adhered to the center or edge of the steel strip.

[0066] The sliding rail and slider mechanism of the base 101 and sliding seat 102 in the movable seat 1, along with the screw drive structure, enables the linear movement of the sliding seat 102, thus increasing the position adjustment function of the sampling device. This linear movement function, combined with the swinging function of the first swing arm 10 and the second swing arm 11, allows the sampling element 2 to adjust its position in three-dimensional space. Compared to a structure that relies solely on the swinging of the swing arms, this further expands the coverage area of ​​different positions on the steel strip, enabling sampling of any area of ​​the steel strip.

[0067] like Figure 4 As shown, the first sliding block 23 has an installation cavity 231, which is connected to the snap-fit ​​gap 2413 on the second sliding block 24. A rotating shaft 232 is provided inside the installation cavity 231, and the tape roll is sleeved on the rotating shaft 232. After the tape is drawn out from the tape roll, it passes through the installation cavity 231 and the end is fixed by the clamping part 241 through the snap-fit ​​gap 2413. When the first sliding block 23 and the second sliding block 24 move away from each other to stretch the tape, the tape roll rotates on the rotating shaft 232 to release the tape. The end of the tape is fixed by the snap-fit ​​gap 2413 formed by the pressure block 2411 and the first sliding groove 242. The first elastic element 2412 applies an elastic force to the pressure block 2411 to keep the tape taut during the stretching process. Push block 3 is slidably positioned within guide groove 221 of mounting block 22. When push block 3 slides out of guide groove 221 and pushes the tape, the tape is continuously released from the tape roll in mounting cavity 231 and adhered to the steel belt under the action of push block 3. A torsion spring can be installed on rotating shaft 232, providing a torque. In the initial stage of adhesion, the tape is manually installed on rotating shaft 232, with the end of the tape clamped in clamping gap 2413. The torsion spring provides a reverse rotational force to rotating shaft 232, keeping the tape taut. The tape adheres to the steel belt, and after removal, the portion adhered to the steel belt is manually removed, and the operation is repeated. The tape will not detach from rotating shaft 232 during operation, and the force of the torsion spring on rotating shaft 232 will not cause the end of the tape to detach from clamping gap 2413.

[0068] The mounting cavity 231 and the rotating shaft 232 provide a fixed mounting structure for the tape roll, allowing the tape to be placed on the first sliding block 23 while preventing the tape roll from shifting during device operation. The design of the mounting cavity 231 communicating with the snap-fit ​​gap 2413 realizes the transition of the tape from the wound state to the clamped and fixed state, ensuring that there is no tangling or jamming during tape stretching. The rotating shaft 232 allows the tape to rotate freely during stretching. The elastic clamping structure of the clamping part 241 cooperates with the tape roll in the mounting cavity 231, maintaining tape tension during tape stretching while adapting to different stretching length requirements, ensuring that the tape is always at the appropriate tension during sampling.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
