Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric feeding swing arm device. Background Technology

[0002] In the modern fabric processing industry, efficient and precise fabric cutting is the core link to ensure production quality and efficiency on the fully automated production line from fabric printing, dyeing, shaping, cutting to finished product sewing. With the continuous growth of diversified demand for fabric types (such as silk, denim, knitted fabric, functional composite fabrics, etc.) in the consumer market, the trend of large-scale and flexible production in fabric processing is significant, which puts forward higher technical requirements for the degree of automation, size adaptability and conveying stability of the fabric cutting process.

[0003] When conveying and feeding stacked block fabrics, the suction cup spacing of traditional swing arm feeding devices is fixed or inconvenient to adjust. When dealing with fabrics of different sizes, the suction range is prone to mismatch. For large fabrics, the inability to suction both ends causes the fabric to sag, wrinkles to form when placed, and difficulty in laying flat. For small fabrics, the suction cup coverage area is too large, causing suction failure. Usually, the suction cups need to be replaced manually, making the operation cumbersome and inefficient.

[0004] Therefore, this utility model provides a fabric feeding swing arm device. Utility Model Content

[0005] To address the problems of fixed or inconvenient suction cup spacing in traditional swing arm feeding devices, which leads to mismatches in the adsorption range for fabrics of different sizes, causing large fabrics to sag and small fabrics to fail to be adsorbed, requiring frequent manual adjustments and resulting in low efficiency, the purpose of this utility model is to provide a fabric feeding swing arm device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric feeding swing arm device, comprising a frame, wherein a swing arm mechanism is provided on one side of the frame for conveying fabric, the swing arm mechanism comprising:

[0007] The adjustment assembly includes a fixed housing on one side of the frame, a gear rotatably mounted in the middle of the fixed housing, and diagonally distributed toothed plates slidingly mounted on both sides of the middle of the fixed housing. The toothed plates and the gear mesh with each other. A servo motor is fixedly mounted on the top of the fixed housing, and the top of the gear is fixedly mounted on the drive end of the servo motor. A fixed plate is fixedly mounted on one end of each of the two toothed plates, and multiple evenly distributed suction cups are fixedly mounted on the bottom of each of the two fixed plates.

[0008] The oscillating assembly, located on one side of the frame, is used to oscillate and convey the fabric.

[0009] Preferably, the swing assembly includes two swing rods rotatably mounted on the upper part of the frame, a transmission rod rotatably mounted on one side of the two swing rods, a fixed frame fixedly mounted on the lower part of one side of the transmission rod, and a drive assembly provided on one side of one of the swing rods.

[0010] Preferably, the drive assembly includes a drive motor fixedly installed on one side of the lower part of the frame, one side of one of the swing arms is fixedly installed on the drive end of the drive motor, and one side of both swing arms is connected by a transmission belt.

[0011] Preferably, a protective cover is fixedly installed on the top of the fixed shell, and the bottom of the fixed frame is fixedly installed on the middle of the top of the protective cover.

[0012] Preferably, a slider is fixedly installed on one side of each of the two toothed plates, and both sliders are slidably engaged in the middle of the fixed shell.

[0013] Preferably, the bottom end of the frame has four evenly distributed mounting holes, and a shock-absorbing pad is embedded in the middle of each of the four mounting holes.

[0014] Beneficial effects

[0015] This utility model provides a fabric feeding swing arm device. Compared with the prior art, it has the following advantages:

[0016] 1. This application uses a servo motor to drive the gear to rotate, which drives two toothed plates to move synchronously relative to each other or in opposite directions, thereby adjusting the distance between the fixed plates. This allows the adsorption range to be automatically adapted according to the size of the fabric, which avoids large fabrics from sagging at both ends and being unable to be laid flat due to unstable adsorption, and also eliminates the need to replace the suction cups for small fabrics. This achieves stable adsorption and efficient transfer of fabrics of different sizes, improving the versatility and ease of operation of the equipment.

[0017] 2. After the drive motor starts, it drives the swing arm to rotate. The two swing arms are synchronously linked through the transmission belt. Under the limiting action of the transmission rod, the fixed frame swings back and forth smoothly. At the same time, the deep groove ball bearing reduces the rotational friction of the swing arm, and the frame shock-absorbing pad reduces the overall operating vibration, so as to avoid the fabric from shifting or falling off during the conveying process, ensure a smooth transition from the stacking area to the target position, and improve the stability and efficiency of fabric feeding.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a fabric feeding swing arm device, including a frame 1, with a swing arm mechanism 2 on one side of the frame 1 for conveying fabric. The swing arm mechanism 2 includes:

[0025] The adjustment assembly 21 includes a fixed housing 211 disposed on one side of the frame 1. A gear 216 is rotatably mounted in the middle of the fixed housing 211. Diagonally distributed toothed plates 214 are slidably engaged on both sides of the middle of the fixed housing 211. The toothed plates 214 and the gear 216 are meshed with each other. A servo motor 213 is fixedly mounted on the top of the fixed housing 211. The top middle of the gear 216 is fixedly mounted on the drive end of the servo motor 213. A fixed plate 217 is fixedly mounted on one end of each of the two toothed plates 214. Multiple evenly distributed suction cups 218 are fixedly mounted on the bottom of each of the two fixed plates 217. The suction cups 218 are made of silicone material to adapt to wrinkled fabrics. Each suction cup 218 has an independently controlled air path and a built-in pressure sensor to monitor the vacuum level in real time. The suction cups 218 that are not in contact with the fabric automatically close to avoid energy waste. The fabric is adsorbed by connecting to a vacuum pump.

[0026] The swing assembly 22 is located on one side of the frame 1 and is used to swing and convey the fabric.

[0027] The swing assembly 22 includes two swing rods 221 rotatably mounted on the upper part of the frame 1. The two swing rods 221 are connected to the swing rods 221 by deep groove ball bearings. A transmission rod 222 is rotatably mounted on one side of the two swing rods 221. A fixed frame 223 is fixedly mounted on the lower part of one side of the transmission rod 222. A drive assembly is provided on one side of one of the swing rods 221.

[0028] The drive assembly includes a drive motor 224 fixedly mounted on one side of the lower part of the frame 1. The drive motor 224 is an Omron servo motor model R88M-1M75030T-S2. One side of one of the swing arms 221 is fixedly mounted on the drive end of the drive motor 224. One side of both swing arms 221 is connected by a transmission belt. A tensioning assembly is provided in the middle of the transmission belt, including a sliding tension wheel, a spring adjustment seat and a guide rail. The tension wheel contacts the inner side of the transmission belt and automatically compensates for the slack of the transmission belt after long-term use through the spring force, maintaining a constant tension and extending the service life of the transmission belt.

[0029] A protective cover 212 is fixedly installed on the top of the fixed housing 211. The bottom end of the fixing frame 223 is fixedly installed in the middle of the top of the protective cover 212. Its servo motor 213 is located inside the protective cover 212, which can protect it and also allows the fixing frame 223 to be connected to the fixed housing 211. The fixing frame 223 and the protective cover 212, as well as the protective cover 212 and the fixed housing 211, are all connected and fixed by bolts.

[0030] A slider 215 is fixedly installed on one side of each of the two toothed plates 214. The two sliders 215 are slidably locked in the middle of the fixed shell 211. The middle of both sides of the fixed shell 211 is provided with sliding grooves for the sliders 215 to match each other, and both are T-shaped structures, so as to ensure the stability of the toothed plates 214 when they move, thereby ensuring the stability of the suction cup 218 adsorbing the fabric.

[0031] The bottom of the frame 1 has four evenly distributed mounting holes 11. Each of the four mounting holes 11 has a shock-absorbing pad embedded in the middle. The frame 1 can be fixedly installed by fitting bolts through the mounting holes 11. At the same time, the embedded shock-absorbing pads can reduce the vibration during equipment operation and improve the stability of transporting and feeding fabric.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the drive motor 224 starts, driving the connected swing arm 221 to rotate. The two swing arms 221 are linked by the transmission belt, causing the fixed frame 223 to swing back and forth under the limit of the transmission rod 222. At the same time, the suction cup 218 adsorbs the fabric, thus transporting the stacked fabric from one side to the other to complete the loading work. When dealing with fabrics of different sizes, the servo motor 213 drives the gear 216 to rotate, which in turn drives the two toothed plates 214 to move synchronously relative to each other or in opposite directions. This allows the distance between the two fixed plates 217 to be adjusted. By adjusting the distance between the two fixed plates 217, when the suction cup 218 adsorbs and transfers fabrics of different sizes, it can always adsorb both ends of the fabric. This avoids the situation where the ends of the fabric fall down when the larger fabric cannot be adsorbed and transported, making it impossible to lay flat when placed, or the smaller fabric cannot be adsorbed, requiring the suction cup 218 to be replaced.
