Description

Technical Field

[0001] This invention relates to a real-time size detection device for cotton wadding products made of fiber wicks. It is a device capable of measuring the length and width of cotton wadding and distinguishing whether it is qualified or not. It belongs to the field of cotton wadding production technology. In particular, it relates to a device that uses a conveyor belt to transport cotton wadding, calculates the width of cotton wadding through a width calculation system, calculates the length of cotton wadding through a length calculation system, and issues an alarm for cotton wadding that is unqualified in length or width. Background Technology

[0002] Cotton wadding, a key filling material for bedding, mattresses, and other household goods, directly impacts the performance and market qualification rate of the final product due to its dimensional stability. Deviations in length or width during wadding production not only hinder subsequent processes (such as sewing and edge sealing) but also result in inconsistent finished product dimensions, affecting the product's neatness, aesthetics, and comfort. Therefore, precise and real-time testing of the length and width of wadding before it leaves the factory is crucial for ensuring product quality, improving production efficiency, and reducing rework rates. Currently, the main method for detecting the size of cotton wadding relies on manual measurement. Manual measurement typically uses a measuring tape or distance measuring device to manually measure the length and width of the cotton wadding at fixed points. This method is not only inefficient and labor-intensive, but also prone to inaccurate results due to human negligence or judgment bias. This is especially true when the surface of the cotton wadding is uneven or not fully unfolded, which can easily lead to errors. Furthermore, it lacks continuity and real-time capability, making it impossible to monitor the size of each cotton wadding online throughout the entire process. This can easily result in defective products flowing into subsequent processes. Although some existing semi-automated detection equipment can use fixed photoelectric sensors or roller encoders for sampling, it cannot perform real-time continuous detection, and most of the equipment measures only one dimension, failing to achieve integrated detection.

[0003] Publication No. CN210481606U discloses a cotton wadding production system, which includes a cotton grabber, a cotton mixing and opening machine, a cotton opening machine, a cotton condenser, a cotton collecting box, a carding machine, and a web laying machine. A conveyor curtain is provided on the lower side of the web laying machine. The production system also includes a wire guiding mechanism, which includes: a wire spool wound with an additive wire; a wire exit roller assembly connected to the web laying trolley of the web laying machine, including two wire guide wheels disposed on one side of the web laying trolley along its traveling direction, the two wire guide wheels clamping the additive wire; and a driving member that drives the wire guide wheels to rotate. In this production system, the detection of cotton wadding size mainly relies on manual measurement. Manual measurement usually uses a measuring tape or distance measuring device to manually measure the length and width of the cotton wadding at fixed points. This method is not only inefficient and labor-intensive, but also prone to inaccurate measurement results due to human negligence or judgment bias. In particular, when there are undulations on the surface of the cotton wadding or it is not fully unfolded, errors are likely to occur. Furthermore, it lacks continuity and real-time monitoring, making it impossible to monitor the size of each cotton wadding online throughout the entire process, which can easily lead to defective products flowing into subsequent processes. Summary of the Invention

[0004] To improve the above situation, the present invention provides a real-time detection device for the size of cotton wadding products, which provides a device for real-time detection of cotton wadding size by conveying cotton wadding through a conveyor belt, calculating the width of cotton wadding through a width calculation system, calculating the length of cotton wadding through a length calculation system, and issuing an alarm for cotton wadding that does not meet the length or width requirements.

[0005] The real-time size detection device for cotton wadding products of the present invention is implemented as follows: The real-time size detection device for cotton wadding products of the present invention consists of a bracket, a T-shaped slide, a support plate, a conveyor roller, a second motor, a conveyor roller, a conveyor belt, a sliding plate, a fixed plate, a first motor, a lead screw, an L-shaped connecting plate, an L-shaped fixed plate, a photoelectric sensor, a detection roller, a fixing plate, screws, and a rotary encoder. The top surface of the bracket has T-shaped grooves, and each bracket corresponds to one of the T-shaped grooves. Preferably, the bracket has a U-shaped structure, consisting of a horizontal plate and two vertical plates. A vertical plate is fixedly placed near each end of the horizontal plate on its bottom surface. Two brackets are provided, arranged parallel to each other and with a certain distance between them. The support plate is fixedly placed on the side of a bracket horizontal plate, and the bracket is positioned between the support plate and another bracket. The second motor is fixedly mounted on the support plate. One end of a conveyor roller is rotatably connected to a bracket. Multiple conveyor rollers are provided. One conveyor roller has its other end passed through the cross plate of the bracket and is fixedly connected to the motor shaft of a second motor. A support bearing is placed between this conveyor roller and the bracket, and this conveyor roller is positioned at the edge. The other ends of the remaining conveyor rollers are rotatably connected to another bracket. The multiple conveyor rollers are connected by a conveyor belt. The sliding plate has a cuboid structure, and its bottom surface is provided with sliding ribs. The sliding plate can be slidably placed on the support through the sliding ribs and T-shaped sliding grooves. One end of the fixed plate is fixedly connected to the side of the sliding plate. The fixed plate extends vertically upward from one end to three-quarters of its length, and then bends at the three-quarters-length point to the other end. The first motor is fixed at three-quarters of the way from the top surface of the fixed plate to the other end. One end of the lead screw is rotatably connected to the sliding plate, and the other end of the lead screw passes through the fixed plate and is fixedly connected to the motor shaft of the first motor. A supporting bearing is placed between the lead screw and the fixed plate. The L-shaped connecting plate extends horizontally to one-half its length, then bends vertically upwards to the other end. One end of the L-shaped connecting plate, at one-half its length, is threadedly connected to the lead screw. One end of the L-shaped fixing plate extends horizontally to the halfway point, then bends vertically downwards to the other end. The halfway point of the L-shaped fixing plate is fixedly connected to the bottom surface of the L-shaped connecting plate. The photoelectric sensor is fixedly positioned between two L-shaped fixing plates, extending from one halfway between the two plates. Two photoelectric sensors are provided, each corresponding to an L-shaped fixing plate, and the two photoelectric sensors are placed alternately. One end of the detection roller is rotatably connected to the side of an L-shaped connecting plate. The cross-sectional diameter of the detection roller at one-twentieth of its length is smaller than the cross-sectional diameter at the other end. The other end of the detection roller has an open structure. The rotary encoder is placed inside the detection roller. One end of the fixed plate is fixedly connected to one end of the rotary encoder. Preferably, the fixing piece is bent at one half to the other end, and the cross-section of the fixing piece from one half to the other end has an arc-shaped structure, with its inner surface fitting against the outer surface of the detection roller. Multiple fixing pieces are provided, and these multiple fixing pieces are arranged at equal intervals along the circumference of the detection roller. Screws are threaded through the fixing plates and placed on the detection rollers; each screw corresponds to one fixing plate. A connecting post is fixedly mounted at the other end of the rotary encoder, and the connecting post is rotatably connected to another L-shaped connecting plate. The real-time size detection device for cotton wadding products of the present invention further includes a width calculation system and a length calculation system. The width calculation system and the length calculation system establish information interaction with the control module on the cotton wadding production line. The width calculation system includes a signal converter and a data processor, and the length calculation system includes a signal converter and a data processor. The signal converter is mounted on the bracket, and the data processor is mounted on the bracket. The two photoelectric sensors are connected to the signal converter via data lines, respectively. The rotary encoder is connected to the signal converter via a data cable. The first motor, the sliding plate, and the second motor are respectively connected to the control module via data transmission lines. The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the control module via a data transmission line. The signal converter can convert the electrical signals from the data collected by the two photoelectric sensors and the rotary encoder into digital signals. The data processor and the signal converter exchange information. When the width and length calculation systems are executed, they mainly implement the following steps: First, the control module adjusts the sliding plate to a designated position, placing it close to the starting end of the conveyor belt. Then, the production line for wadding fiber products is started. The control module drives the first motor to rotate the screw, thereby adjusting the height of the detection roller to be slightly higher than the height of the cotton wadding. The control module also drives the second motor to rotate the conveyor roller, which in turn drives the conveyor belt, causing the cotton wadding to move forward with the conveyor belt. During the cotton wadding conveying process, the control module collects the distance between the two photoelectric sensors and the cotton wadding through two photoelectric sensors. This data is transmitted to the width calculation system in real time. The width calculation system uniformly and randomly selects several sets of data from the collected data and calculates the distance between the two photoelectric sensors and the distances from the two photoelectric sensors to the two sides of the cotton wadding, thereby obtaining the width of the cotton wadding at these points. The width is measured until the cotton wadding is completely conveyed onto the conveyor belt. The width data is then sent back to the data processor. Simultaneously, the control module controls the second motor to stop the conveyor belt. If the width value deviates from the preset range, the control module will issue an alarm and remove the cotton wadding. If the width value is within the preset range, the control module will control the first motor to rotate the lead screw, so that the height of the detection roller is slightly lower than the height of the cotton wadding. Then, the control module will drive the sliding plate to slide, so that the detection roller rotates on the cotton wadding, allowing the detection roller to completely crush the cotton wadding. The length calculation system multiplies the number of pulses generated by the rotary encoder by the circumference of the detection roller to obtain the length of the cotton wadding, and sends the data to the data processor. If the length value deviates from the preset range, the control module will issue an alarm and remove the cotton wadding. If the length value is within the preset range, the control module will control the second motor to drive the conveyor belt to continue operating for the size detection of the next cotton wadding. Furthermore, the outer surface of the detection roller is fitted with an anti-slip sleeve, which has a cylindrical structure, is made of rubber, and has a large frictional force on its outer surface. Furthermore, the outer surface of the detection roller is provided with a circular protrusion, and there are multiple circular protrusions, which are evenly distributed on the outer surface of the detection roller. Beneficial effects

[0006] First, by measuring the distance difference between the two sensors and the cotton quilt, the width of the cotton quilt can be accurately calculated. The rotary encoder is built into the detection roller and can accurately record the rotation data of the roller, thereby calculating the length of the cotton quilt and ensuring measurement accuracy.

[0007] Second, the continuous operation mode of the automated device greatly shortens the inspection cycle. The length and width of the cotton quilt are inspected one after another, and the whole process can be completed automatically in a short time, saving a lot of time compared with manual operation.

[0008] Third, automated testing reduces direct contact between operators and machinery, avoiding damage and contamination to the cotton quilt. Attached Figure Description

The halfway point of the L-shaped fixing plate (14) is fixedly connected to the bottom surface of the L-shaped connecting plate (3). The photoelectric sensor (13) is fixedly placed on the side of the L-shaped fixing plate (14) from one halfway point to the other end. The photoelectric sensor (13) is placed between the two L-shaped fixing plates (14). Two photoelectric sensors (13) are provided, and each photoelectric sensor (13) corresponds to an L-shaped fixing plate (14). The two photoelectric sensors (13) are placed alternately. One end of the detection roller (12) is rotatably connected to the side of an L-shaped connecting plate (3).

The real-time size detection device for cotton wadding (fiber wadding products) of the present invention further includes a width calculation system and a length calculation system. The width calculation system establishes information interaction with the control module on the cotton wadding (fiber wadding product) production line, and the length calculation system establishes information interaction with the control module on the cotton wadding (fiber wadding product) production line. The width calculation system includes a signal converter and a data processor, and the length calculation system includes a signal converter and a data processor. The signal converter is placed on the bracket (7), and the data processor is placed on the bracket (7). The two photoelectric sensors (13) are connected to the signal converter via data lines, respectively. The rotary encoder (17) is connected to the signal converter via a data cable. The first motor (1), the sliding plate (5), and the second motor (11) are respectively connected to the control module via data transmission lines. The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the control module via a data transmission line. The signal converter can convert the electrical signals of the data collected by the two photoelectric sensors (13) and the rotary encoder (17) into digital signals. The data processor and the signal converter exchange information. When the width calculation system and length calculation system are executed, the following steps are mainly implemented: First, the sliding plate (5) is adjusted to a specified position by the control module so that the sliding plate (5) is placed close to the starting end of the conveyor belt (8). Then, the operation of the wadding fiber product production line is started. The control module drives the first motor (1) to drive the screw (4) to rotate, thereby adjusting the height of the detection roller (12) so that its height is slightly higher than the height of the cotton wadding. The control module also drives the second motor (11) to drive the conveyor roller (9) to rotate, thereby driving the conveyor belt (8) so that the cotton wadding moves forward with the movement of the conveyor belt (8). During the cotton wadding conveying process, the control module collects the distance between the two photoelectric sensors (13) and the cotton wadding through the two photoelectric sensors (13). These data are transmitted to the width calculation system in real time. The width calculation system selects several sets of data evenly and randomly from the collected data, and calculates the distance between the two photoelectric sensors (13) minus the distance between the two photoelectric sensors (13) and the two sides of the cotton wadding, thereby obtaining these points. The width of the cotton quilt is measured until the cotton quilt is completely conveyed onto the conveyor belt. The width data is sent back to the data processor. At the same time, the control module controls the second motor (11) to stop the conveyor belt (8). If the width value deviates from the preset range, the control module will issue an alarm and remove the cotton quilt. If the width value is within the preset range, the control module will control the first motor (1) to drive the screw (4) to rotate, so that the height of the detection roller (12) is slightly lower than the height of the cotton quilt. Then the control module drives the sliding plate (5) to slide, so that the detection roller (12) rotates on the cotton quilt and completely crushes the cotton quilt. The length calculation system multiplies the number of pulses generated by the rotary encoder (17) by the circumference of the detection roller (12) to obtain the length of the cotton quilt and sends the data to the data processor. If the length value deviates from the preset range, the control module will issue an alarm and remove the cotton quilt. If the length value is within the preset range, the control module will control the second motor (11) to drive the conveyor belt (8) to continue running and perform the size detection of the next cotton quilt. Example 2

[0012] The difference between this embodiment and embodiment 1 is that: the outer side of the detection roller (12) is covered with an anti-slip sleeve (18), the anti-slip sleeve (18) has a cylindrical structure, the anti-slip sleeve (18) is made of rubber, and the outer side of the anti-slip sleeve (18) has a large friction force. When using it, when measuring the length of the cotton quilt, the anti-slip sleeve (18) can increase the friction force when it comes into contact with the cotton quilt, effectively avoiding slippage, so as to accurately measure the length of the cotton quilt; Example 3

[0013] The difference between this embodiment and embodiment 1 is that: the outer side of the detection roller (12) is provided with a circular protrusion (19), and there are multiple circular protrusions (19). The multiple circular protrusions (19) are evenly distributed on the outer side of the detection roller (12). When in use, the circular protrusions (19) can disperse the pressure of the roller on the cotton wadding, reduce the occurrence of local over-compaction, and at the same time can form tiny pits on the surface of the cotton wadding, increasing the elasticity and softness of the cotton wadding; The bracket (7) has a U-shaped structure and consists of a horizontal plate and two vertical plates. The design of fixing a vertical plate to the bottom surface of the horizontal plate near both ends provides good stability and ensures the stability of the equipment during operation. One end of the conveyor roller (9) is rotatably connected to a bracket (7). There are multiple conveyor rollers (9). One of the conveyor rollers (9) has its other end passing through the cross plate of the bracket (7) and is fixedly connected to the motor shaft of the second motor (11). A support bearing is placed between the conveyor roller (9) and the bracket (7). The conveyor roller (9) is placed at the edge position. The other end of the other conveyor rollers (9) is rotatably connected to another bracket (7). This design enables the cotton wadding to move smoothly on the conveyor belt (8), reduces the shaking of the cotton wadding during the measurement process, and improves the accuracy of the measurement. Two photoelectric sensors (13) are provided. Each photoelectric sensor (13) corresponds to an L-shaped fixing plate (14). The staggered placement of the two photoelectric sensors (13) can measure the distance from each photoelectric sensor (13) to the two sides of the cotton quilt, thereby obtaining the width of the cotton quilt. At the same time, the staggered placement of the two photoelectric sensors (13) can prevent them from affecting each other or even causing damage, thus ensuring the stability and accuracy of the measurement process. The detection roller (12) has an open structure at the other end, which provides space for the rotary encoder (17) and reduces the weight of the detection roller (12), making the detection roller (12) rotate more flexibly and thus improving the accuracy of the measurement. The width calculation system and the control module on the cotton quilt production line establish information interaction, and the length calculation system and the control module on the cotton quilt production line establish information interaction. The first motor (1), the sliding plate (5), and the second motor (11) are respectively connected to the control module through data transmission lines. The intelligent control module can automatically adjust the operating status of the production line according to the measurement data, which improves production efficiency and product quality, while reducing the need for manual operation and reducing human error in the production process. The goal is to enable the conveyor belt to transport cotton wadding, calculate the width of the cotton wadding using a width calculation system, calculate the length of the cotton wadding using a length calculation system, and issue an alarm for cotton wadding that does not meet the length or width requirements.
