Description

Technical Field

[0001] This utility model belongs to the field of velvet product processing technology, specifically, it relates to an automatic brushing mechanism based on visual positioning. Background Technology

[0002] Industrial brushing machines are mainly used in the finishing processes of the textile industry to brush patterns onto fabrics such as chemical fibers, blended fabrics, velvet, and plush, improving the plush texture or pattern effect on the fabric surface. Their core functions include perforation, embossing, and edge trimming to achieve specific appearance and tactile requirements.

[0003] The existing brushing mechanism still has the following problems when in use:

[0004] Traditional brushing techniques rely on manual or mechanical fixed trajectories, making it difficult to dynamically adjust the brushing position according to the real-time condition of the fabric. This results in pattern offsets and misalignments. Without visual feedback, the fabric can shift by ±2mm due to tension fluctuations and traction errors. Traditional brushing equipment has a fixed number, angle, and diameter of brush heads. Changing patterns requires stopping the machine to replace mechanical parts, resulting in high production changeover costs. A single machine can only support 1-2 patterns, and the changeover time is ≥30 minutes, which cannot meet the needs of small-batch, multi-variety orders.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0006] Therefore, in order to solve the above problems, this utility model provides an automatic brushing mechanism based on visual positioning. Utility Model Content

[0007] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an automatic flower brushing mechanism based on visual positioning.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] The visual positioning-based automatic fabric brushing mechanism includes a brushing machine frame, on which a control system component with signal receiving, processing, and transmission functions is installed. Inside the brushing machine frame, an oil-heated main roller for heating the fabric is installed. On one side of the oil-heated main roller, a brushing component for brushing the fabric surface into a pattern is provided. Below the brushing component, a cylinder component for controlling the engagement and disengagement of the brushing component with the oil-heated main roller is installed. At the top of the brushing machine frame, a camera component for real-time photography is also installed.

[0010] The brushing assembly includes a crossbeam fixed on the frame of the brushing machine. The angle of the crossbeam is adjustable, and a brush head module is slidably connected to the crossbeam.

[0011] Furthermore, the fabric spreading machine frame is equipped with several sets of spreading rollers used to spread the fabric and prevent it from wrinkling.

[0012] Furthermore, the brushing machine frame is equipped with a traction roller that pulls the fabric into the oil-heated main roller, and the traction roller is positioned between two spreading rollers.

[0013] Furthermore, the lower left and right corners of the brushing machine frame are equipped with guide rollers for guiding and passing the fabric.

[0014] Furthermore, the crossbeam is mounted on the output end of the cylinder assembly via a connecting frame. Linear slide rails A and B are installed on both sides of the crossbeam. A rack is installed on the inner side of the linear slide rail B. An assembly plate is slidably connected to the linear slide rails A and B. A servo drive motor is fixedly mounted on the assembly plate. A gear is installed on the output end of the servo drive motor. The gear meshes with the rack. A brush head module is also mounted on the top of the assembly plate. The brush assembly also includes an angle rotation motor mounted on the brush machine body. The output end of the angle rotation motor is connected to the connecting frame.

[0015] Furthermore, a mounting bracket is fixedly installed at the top of the brushing machine frame, and the camera assembly is mounted at the top of the mounting bracket.

[0016] Furthermore, the servo drive motor, brush head module, angle rotation motor, cylinder assembly, and camera assembly are electrically connected to the control system assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, the camera component captures and processes images in real time, then sends position information through the control system component. Combined with the precise transmission of the servo drive motor, a closed-loop system of "image recognition - position feedback - motion control" is formed, significantly improving the alignment accuracy between the brush head and the fabric surface and reducing errors caused by manual intervention. The servo motor drives the brush head to move left and right, responding to real-time position commands from the vision system and adapting to minute displacements or deformations during fabric movement, ensuring consistent and continuous patterns.

[0019] In this invention, after the oil-heated main roller softens the fabric fibers, the brush head can efficiently comb and shape the fluff. Combined with the tension control of the traction roller and the spreading roller, it avoids fabric wrinkles or stretching deformation, ensuring clear and continuous patterns. The engagement and disengagement of the brush head and the oil-heated roller surface are independently controlled by the cylinder assembly, which can start and stop partial brushing actions as needed, reducing ineffective contact wear, extending equipment life and reducing energy consumption.

[0027] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0028] Please see Figure 1According to an embodiment of this utility model, the automatic brushing mechanism based on visual positioning includes a brushing machine frame 1. A control system component 10 with signal receiving, processing, and transmission functions is installed on the brushing machine frame 1. An oil-heated main roller 2 is installed inside the brushing machine frame 1. The core function of the oil-heated main roller 2 is to provide a uniform and stable heat source to the fabric through internally circulated and heated heat-conducting oil. Its main functions include: softening fabric fibers (heating softens the fabric fibers, improving their plasticity, facilitating subsequent brushing head orientation of the fabric surface), promoting pattern shaping (after the fluff is brushed out during the brushing process, the fabric is more likely to form a stable pattern structure under heating, preventing the pattern from collapsing or deforming after cooling), and improving processing efficiency (the heated fabric is easier to pull and unfold, reducing abnormalities such as fabric jamming and wrinkles caused by fabric stiffness). (Situation) A brushing component 6 is provided on one side of the oil-heated main roller 2 to brush the fabric surface into a pattern. Below the brushing component 6 is a cylinder component 7 that controls the engagement and disengagement of the brushing component 6 and the oil-heated main roller 2. Through the extension and retraction of the cylinder, the brushing component 6 and the oil-heated main roller 2 are contacted and separated, thereby controlling the start and stop of the brushing operation according to the needs of the production process, ensuring the accuracy and controllability of the brushing process. A mounting frame 8 is fixedly installed at the top of the brushing machine frame 1, and a camera component 9 is installed at the top of the mounting frame 8. The main function of the camera component 9 is to take pictures in real time. It can monitor the fabric surface in real time and transmit the captured image information to the control system component 10, providing positional basis for the precise operation of the brushing component 6, ensuring that the brushing head can accurately brush out the pattern at the specified position, and improving the accuracy and quality of the brushing.

[0029] Please see Figure 2 The brushing assembly 6 includes a crossbeam 61 fixed on the brushing machine frame 1. The angle of the crossbeam 61 is adjustable, and a brush head module 68 is slidably connected to the crossbeam 61. The brush head module 68 acts directly on the heated and softened fabric surface. By rotating the bristles on the brush head module 68, the pile is combed in a directional manner, forming an embossed three-dimensional pattern (such as wave pattern, geometric grid pattern, etc.) on the fabric surface. The number of brush head modules 68 can be increased or decreased as needed. The failure of a single module will not affect the overall production, improving the reliability of the equipment. The diameter of the brush head can be customized within the range of φ20-φ70mm. By adjusting the diameter, the contact area with the fabric surface is controlled. The larger the diameter, the wider the contact surface and the coarser the pattern formed; the smaller the diameter, the more concentrated the contact surface and the more delicate the pattern. Each set of brush heads is driven by an independent motor and can achieve bidirectional rotation (forward / reverse). When rotating forward, the bristles lift the fabric pile upward to form a three-dimensional pattern, and when rotating in reverse, they flatten the pile to produce a gradient texture.

[0030] Please see Figure 1 The frame 1 of the brushing machine is equipped with several sets of spreading rollers 4. The multiple sets of spreading rollers 4 are used to spread the fabric, prevent the fabric from wrinkling, and ensure that the fabric is flat before entering the subsequent processes (heating, brushing).

[0031] Please see Figure 1 The brushing machine frame 1 is equipped with a traction roller 3 that pulls the fabric into the oil-heated main roller 2. The traction roller 3 is located between two spreading rollers 4. The traction roller 3 is an active roller (driven by a variable frequency motor on the brushing machine, which is existing technology and is not shown in the figure). The roller surface is made of elastic material (to increase the friction with the fabric). The elastic material is preferably rubber or polyurethane. The fabric is pulled from the spreading roller 4 to the oil-heated main roller 2 through friction transmission. There is a difference in linear speed between the traction roller 3 and the oil-heated main roller 2 (the speed of the traction roller is slightly faster than that of the heating main roller). This speed difference will keep the fabric in a taut state between the two and prevent the fabric from loosening.

[0032] Please see Figure 1 The lower left and right corners of the brushing machine frame 1 are equipped with guide rollers 5 for guiding and passing the fabric. The guide rollers 5 are passive rollers (rotated by the fabric). The roller surface is made of stainless steel / chrome plating. The main functions include: guiding function (in the fabric transmission path, the guide roller changes the transmission direction of the fabric by adjusting the installation position (such as tilting or leveling)) and passing function, namely support and friction reduction (the guide roller supports the fabric and reduces the direct friction between the fabric and the frame and other components).

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The crossbeam 61 is mounted on the output end of the cylinder assembly 7 via a connecting bracket. Linear slide rails A62 and B63 are mounted on both sides of the crossbeam 61. A rack 64 is mounted on the inner side of the linear slide rail B63. An assembly plate 65 is slidably connected to the linear slide rails A62 and B63. A servo drive motor 66 is fixedly mounted on the assembly plate 65. A gear 67 is mounted on the output end of the servo drive motor 66, and the gear 67 meshes with the rack 64. A brush head module 68 is also mounted on the top of the assembly plate 65. The brush assembly 6 also includes an angle rotation motor mounted on the brush machine body. The output end of the angle rotary motor 69 is connected to the connecting frame. The servo drive motor 66, brush head module 68, angle rotary motor 69, cylinder assembly 7 and camera assembly 9 are electrically connected to the control system assembly 10. The servo drive motor 66 drives the gear 67 to mesh with the rack 64. According to the position information fed back by the camera assembly 9, the brush head module 68 is controlled to move laterally and precisely on the linear slide rails A62 and B63 to achieve continuous positioning of complex patterns. The angle rotary motor 69 adjusts the tilt angle of the entire assembly to change the cutting direction of the brush bristles and the fabric.

[0034] The working principle of the vision-based automatic brushing mechanism is as follows: The fabric first enters the machine body through the guide roller 5. Its smooth roller surface reduces friction and ensures that the fabric is smoothly transported along the preset path. Then, the spreading roller 4 eliminates longitudinal / transverse wrinkles of the fabric through lateral expansion force (such as a threaded roller surface or an arc-shaped structure), preventing the pattern from being deformed due to wrinkles during subsequent heating and brushing. The traction roller 3, as the active roller, pulls the fabric at a speed slightly higher than that of the oil-heated main roller 2, forming a speed difference to keep the fabric under constant tension, ensuring that the fabric is flat and adheres to the surface of the oil-heated main roller 2. The camera component 9 captures the image of the fabric surface, and after analysis by the control system component 10, the pattern position coordinates are transmitted to the brushing component control system in real time to guide the brushing head module 68 to move precisely. The cylinder component 7 pushes the brushing head module 68 to contact the fabric on the oil-heated main roller 2. The servo drive motor 66 drives the gear 67 to mesh with the rack 64, driving the brushing head module 68 to move laterally to the target position.
