Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, and in particular to a fabric separation and flipping device for a marking machine. Background Technology

[0002] The marking machine uses a numbering wheel to mark the processed fabric, facilitating the recording of production batch information. During marking, each piece of fabric needs to be flipped up for marking. For fabrics thicker than 0.1mm, a robotic arm can flip them up one by one before driving the numbering wheel down to mark. However, for very thin fabrics, such as those less than 0.1mm thick, manual flipping is necessary. This is because existing robotic arms cannot flip thinner fabrics, and manual flipping is inefficient, time-consuming, and labor-intensive, increasing labor costs. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a fabric separation and flipping device for a marking machine. It has a simple structure and is easy to operate. It is suitable for gripping fabric strips of different thicknesses, especially thin fabric strips, thus saving labor costs.

[0004] The technical solution adopted is as follows:

[0005] A fabric separation and flipping device for a marking machine includes a roller mechanism for rolling and unrolling fabric, and a drive mechanism for driving the roller mechanism and assisting in flipping the fabric. The roller mechanism includes a roller drive motor mounted on a motor mounting frame, and a roller assembly driven by the drive motor to roll fabric forward and unroll fabric in reverse. The motor mounting frame has a base plate that cooperates with the roller assembly to roll fabric. The motor mounting frame also has a detector at the corresponding position of the roller mechanism to detect whether the fabric is being rolled in. The roller assembly has a corresponding fabric roll-in gap between the corresponding roller and the base plate.

[0006] Furthermore, the roller assembly includes a first roller mounted on the output shaft of the roller drive motor, a second roller for rolling and unrolling fabric, a roller mounting bracket for mounting the two rollers, and a timing belt located between the first roller and the second roller.

[0007] Furthermore, the motor mounting bracket is also equipped with a pressure structure that drives the second roller to cooperate with the base plate.

[0008] Furthermore, the motor mounting bracket is provided with a fulcrum for the roller mounting bracket to rotate, and the driving pressure structure is a driving pressure spring located between the motor mounting bracket and the roller mounting bracket.

[0009] Furthermore, the roller mounting bracket is mounted on the output shaft of the roller drive motor, and a bearing is provided between the roller mounting bracket and the output shaft of the motor.

[0010] Furthermore, the motor mounting bracket is provided with a movable slot for accommodating the mounting roller bracket.

[0011] Furthermore, the motor mounting bracket is equipped with a cloth roll cover, which covers the roller mechanism and the base plate.

[0012] Furthermore, the upper end of the roller mechanism is provided with a drive cylinder to drive the roller mechanism to move up and down.

[0013] Furthermore, the drive mechanism is mounted on the frame, and the roller mechanism is rotatably mounted on the frame. The drive mechanism includes a drive motor, an arc-shaped toothed plate mounted on the roller mechanism, and a gear that engages with the arc-shaped toothed plate. The gear and the drive motor are connected via a synchronous belt pulley assembly.

[0014] Furthermore, the frame is also equipped with an air blowing mechanism that drives the fabric to flip.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a drive mechanism for separating and flipping fabric in a marking machine, including a roller mechanism and a drive mechanism for driving the roller mechanism. The roller mechanism includes a roller drive motor and a roller assembly mounted on a motor mounting plate. The motor mounting plate also has a base plate. The roller assembly includes at least one roller, and a corresponding fabric winding gap is provided between the corresponding roller and the base plate. The roller drive motor can directly or indirectly drive the corresponding roller to cooperate with the base plate for winding and unwinding fabric. The gap between the corresponding roller and the base plate can be adjusted according to the actual fabric thickness, making it widely applicable.

[0017] Preferably, the roller assembly includes a roller mounting frame, a first roller directly connected to a roller drive motor, a second roller for winding and unwinding fabric, and a timing belt positioned between the two rollers. The roller mounting frame is rotatably mounted on a motor mounting plate. A pressure structure is provided between the motor mounting plate and the roller mounting frame to press the second roller close to the base plate, ensuring a gap between the second roller and the base plate. The roller drive motor can control the forward or reverse rotation of the timing belt and the second roller by driving the first roller to rotate forward or reverse, thereby controlling the winding and unwinding of fabric. The second roller cooperates with the base plate, rotating forward to wind fabric and rotating reverse to unwind fabric. The drive mechanism can drive the roller mechanism to press down on the wound fabric and lift up on the unwound fabric, cooperating with the air blowing mechanism to complete the flipping of the fabric strip.

[0018] This invention features a simple structure and a straightforward method for gripping fabric strips. It is suitable for thinner fabric strips, such as those less than 0.1mm thick, making it widely applicable. Furthermore, it eliminates the need for needle-punching during gripping, preserving the integrity of the fabric strip and reducing wear. The electronic control system for picking up and flipping the fabric strip saves manpower and reduces labor costs. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] refer to Figure 1-6 A fabric separation and flipping device for a marking machine includes a roller mechanism 1 for rolling and unrolling fabric, and a drive mechanism 2 for driving the roller mechanism 1 to rotate and assist in flipping the fabric. The roller mechanism 1 includes a roller drive motor 101 mounted on a motor mounting frame 3, and a roller assembly 102 driven by the drive motor to roll the fabric forward and unroll it in reverse. The motor mounting frame 3 is provided with a base plate 5 that cooperates with the roller assembly 102 to roll the fabric. The motor mounting frame 3 is also provided with a detector 11 at the corresponding position of the roller mechanism 1 to detect whether the fabric is rolled in. The roller assembly 102 has a corresponding fabric roll-in gap between the corresponding roller and the base plate 5.

[0026] The roller assembly 102 may include at least one roller. The roller drive motor 101 can directly drive the corresponding roller to cooperate with the base plate for fabric winding, for example, by directly mounting the corresponding roller on the output shaft of the roller drive motor 101; or it can indirectly drive the corresponding roller to wind the fabric, for example, by mounting another roller on the roller drive motor 101 and a synchronous belt between the two rollers, driving the other roller to rotate, and driving the roller that needs to be wound to rotate through the synchronous belt transmission. The distance between the corresponding roller used for winding the fabric and the base plate 5 can be adjusted according to the thickness of the fabric to be wound. The gap between the base plate 5 and the base plate 5 can be adjusted by adjusting the installation position of the base plate 5 or the roller, or by directly replacing rollers of different diameters, so that fabrics of different thicknesses can be wound.

[0027] The detector 11 is mounted on the motor mounting bracket 3 via a mounting bracket. The detector 11 can adopt existing technology, such as a photoelectric detector. A laser emitter corresponding to the photoelectric detector can be set at the lower end of the base plate 5. If the cloth strip is not rolled up, the laser is emitted to the photoelectric detector and detected by the photoelectric detector, and then the roller mechanism 1 is driven to roll up the cloth again. If the cloth strip is rolled up and blocks the laser emission, the photoelectric detector will not receive the light signal, and the drive mechanism 2 will drive the roller mechanism 1 to rise.

[0028] Preferably, the roller assembly 102 includes a first roller 1021 mounted on the output shaft 4 of the roller drive motor 101, a second roller 1022 for rolling and unrolling fabric, a roller mounting bracket 7 for mounting the two rollers, and a timing belt 1023 located between the first and second rollers.

[0029] The motor mounting bracket 3 is further provided with a driving structure 6 that drives the second roller 1022 to cooperate with the base plate 5. The motor mounting bracket 3 has a fulcrum for the rotation of the roller mounting bracket 7. Preferably, the driving structure 6 is a driving spring located between the motor mounting bracket 3 and the roller mounting bracket 7. The driving structure 6 is designed to drive the second roller 1022 to cooperate with the base plate, ensuring the gap between the base plate and the second roller 1022 for easy fabric winding. The relative position of the second roller 1022 and the base plate can be controlled according to the actual fabric thickness.

[0030] In this embodiment, the roller mounting bracket 7 is mounted on the output shaft 4 of the roller drive motor 101, that is, the output shaft 4 serves as the fulcrum. A bearing 8 is provided between the roller mounting bracket 7 and the output shaft 4 of the motor.

[0031] The bearing is provided so that the output shaft 4 can drive the first roller 1021 to rotate independently, without the roller mounting bracket 7 swinging.

[0032] The motor mounting bracket 3 is provided with a movable groove 9 for accommodating the roller mounting bracket 7. The roller mounting bracket 7 is located within the movable groove 9 and does not protrude outward, saving space.

[0033] The motor mounting bracket 3 is equipped with a fabric roll cover 10, which covers the roller mechanism 1 and the base plate 5. The fabric roll cover 10 is provided to protect the internal roller mechanism 1.

[0034] The upper end of the roller mechanism 1 is provided with a drive cylinder 13 for driving the roller mechanism 1 to move up and down.

[0035] The drive mechanism 2 is mounted on the frame 12, and the roller mechanism 1 is rotatably mounted on the frame 12 via a mounting block. The drive mechanism 2 includes a drive motor 201, an arc-shaped toothed plate 202 mounted on the roller mechanism 1, and a gear 203 that meshes with the arc-shaped toothed plate 202. The gear 203 and the drive motor 201 are connected via a synchronous belt pulley assembly 204. The drive motor 201 drives the gear 203 to rotate through the synchronous belt pulley assembly 204. The rotation of the gear 203 drives the arc-shaped toothed plate 202 to move, thereby driving the roller mechanism 1 to move. The arc-shaped toothed plate 202 is mounted on the drive cylinder 13.

[0036] The marking machine also includes a worktable and a marking mechanism mounted on the frame. Several layers of cloth strips to be marked are placed on the worktable. The marking mechanism and roller mechanism 1 are both located at the top of the worktable. The marking mechanism adopts existing technology. After the number roller is inked, it is driven downward to contact the cloth strip and mark the cloth strip.

[0037] After the fabric strip is marked, the marking mechanism retracts, and the drive mechanism 2 drives the roller mechanism 1 to move to the upper end of the fabric strip, as shown. Figure 1 The drive cylinder 13 drives the roller mechanism 1 to press down and contact the fabric strip. At this time, the roller drive motor 101 drives the first roller 102 to rotate, which in turn drives the second roller 1022 to rotate via the synchronous belt 1023. Since the second roller 1022 is in contact with the fabric strip, the forward rotation of the second roller can roll the fabric strip into the gap between the second roller 1022 and the base plate 5. The detector 11 detects whether the fabric strip is rolled in. If the fabric strip is not rolled in, the drive roller mechanism 1 rolls the fabric again; if the fabric strip is rolled in, the drive mechanism 2 drives the roller mechanism 1 to lift the fabric strip, and then the drive motor 101 drives the second roller 1012 to reverse and bring the fabric strip out. The frame is also equipped with an air blowing mechanism to drive the fabric to flip. The air blowing mechanism blows the fabric strip to the other side, completing the flip.

[0038] This invention utilizes a roller that rotates clockwise to roll up the fabric and counterclockwise to unroll it. The friction between the roller's outer synchronous belt and the fabric strip draws the fabric into the gap between the roller and the base plate. This method can also be used for thinner fabric strips, such as those less than 0.1mm thick. A drive mechanism 2 then drives the roller mechanism to lift the rolled-up fabric strip, thus gripping it. Compared to robotic arms, this invention is suitable for thinner fabric strips and has a wider range of applications. Furthermore, this method eliminates the need for needle punching, preventing damage to the fabric and preserving its integrity.

[0039] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
