A fabric transport device

Abstract

A fabric transport device includes a frame, a first moving component, and a support frame. The first moving component is connected to the frame, and the support frame is connected to the first moving component. The first moving component drives the support frame to move and change its height. The support frame supports the fabric roll. The first moving component moves the support frame to a corresponding position according to the fabric roll diameter, so that the bottom of the fabric roll is away from the frame, reducing friction between the fabric roll and the frame and causing wear on the fabric roll. It also avoids the situation where the fabric roll is too high, resulting in a small contact area between the fabric and the first power roller shaft, which would affect the stability of fabric transport. This facilitates adaptation to the installation height requirements of fabric rolls with different diameters.

Description

Technical Field

[0001] This application relates to the field of textile equipment, and more particularly to a fabric transport device. Background Technology

[0002] In garment manufacturing, home textile processing, and other fields, fabric spreading machines are key automated equipment used to smoothly and efficiently spread rolls of fabric onto a cutting table according to a set length and number of layers, preparing them for subsequent cutting processes. Their core functions include automatic unwinding, traction, alignment, and flattening of the fabric rolls, significantly improving production efficiency and fabric spreading quality while reducing labor costs.

[0003] Chinese patent CN220299964U discloses a garment manufacturing fabric spreading machine, which includes a machine housing, and inside the machine housing are a fabric roll, a first auxiliary roller, an A motor, and a first power roller, with the A motor connected to the first power roller.

[0004] Regarding the aforementioned technologies, to prevent the outer edge of the fabric roll from rubbing against the inner wall of the equipment casing during rotation and unwinding, thus avoiding fabric wear or pilling, the fabric roll is typically installed away from the ground of the equipment casing. When the fabric spreading machine spreads fabric rolls of different diameters, because the installation height of the fabric roll is fixed, there are situations where the installation position is too high, resulting in insufficient contact area between the fabric and the first power roller shaft, affecting the traction effect; conversely, there are situations where the installation position is too low, causing the fabric roll to rub against the bottom surface of the equipment casing. Therefore, a fixed installation height cannot meet the installation requirements of fabric rolls of different diameters. Utility Model Content

[0005] To accommodate the installation height requirements of fabric rolls with different diameters, this application provides a fabric transport device.

[0006] The fabric transport device provided in this application adopts the following technical solution:

[0007] A fabric transport device includes a frame, a first moving component, and a support frame. The first moving component is connected to the frame, and the support frame is connected to the first moving component. The first moving component is used to move the support frame and change its height. The support frame is used to support the fabric roll.

[0008] By adopting the above technical solution, when in use, the fabric roll is placed on the support frame, and the first moving component moves the support frame to the corresponding position according to the diameter of the fabric roll, so that the bottom of the fabric roll is away from the frame, reducing the friction between the fabric roll and the frame and causing wear on the fabric roll. In addition, the first moving component moves the support frame according to the diameter of the fabric roll, which can avoid the situation where the fabric roll position is too high, resulting in a small contact area between the fabric and the first power roller shaft, affecting the stability of the fabric transportation. This makes it easier to adapt to the installation height requirements of fabric rolls with different diameters.

[0009] Optionally, there are two first moving components and two support frames, with each support frame connected to a first moving component.

[0010] By adopting the above technical solution, two support frames are provided. In use, both support frames are used to support the fabric roll, thereby improving the stability of the fabric roll transportation process.

[0011] Optionally, the first moving component includes a first chain, a first sprocket, and a second sprocket. The first sprocket and the second sprocket are both rotatably connected to the frame. One end of the first chain is sleeved on the first sprocket, and the other end of the first chain is sleeved on the second sprocket. The first sprocket and the second sprocket are both meshed with the first chain. The frame is connected to a rotating component, which is used to drive the first sprocket to rotate. The support frame is connected to the first chain.

[0012] By adopting the above technical solution, the rotating component drives the first sprocket to rotate, the first sprocket drives the first chain to transmit, which in turn drives the second sprocket to rotate, and the first chain drives the support frame to move, thereby facilitating the change of the height between the support frame and the fabric roll.

[0013] Optionally, the frame is connected to a movable frame and a second movable component. The second movable component is connected to the frame, and the movable frame is connected to the second movable component. The second movable component is used to drive the movable frame to move and drive the movable frame to approach the feeding end of the first movable component. The movable frame is used to support the fabric roll.

[0014] By adopting the above technical solution, when in use, the fabric roll is placed on the moving frame, and the second moving component drives the moving frame to move and move it closer to the feeding end of the first moving component. The fabric roll follows the moving frame, so that the fabric roll is close to the feeding end of the first moving component, which facilitates the feeding of the fabric roll to the first component, further reducing manual handling and reducing labor costs.

[0015] Optionally, the second moving component includes a second chain, a third sprocket, and a fourth sprocket. The third sprocket and the fourth sprocket are rotatably connected to the frame. One end of the second chain is sleeved on the third sprocket, and the other end of the second chain is sleeved on the fourth sprocket. The third sprocket and the fourth sprocket are both engaged with the second chain. The frame is connected to a driving component, which drives the third sprocket to rotate. The moving frame is connected to the second chain.

[0016] By adopting the above technical solution, when the fabric roll is placed on the moving frame, the driving component drives the third sprocket to rotate, the third sprocket drives the second chain to transmit, the second chain to transmit drives the fourth sprocket to rotate, and the moving frame follows the second chain to transmit, thereby moving the moving frame and the fabric roll closer to the feeding end of the first moving component, which facilitates the feeding of the fabric roll and reduces labor costs.

[0017] Optionally, the rotating component includes a third chain, a fifth sprocket, a sixth sprocket, and a first motor. The fifth sprocket is connected to a rotating rod and is rotatably connected to the frame via the rotating rod. Both first sprockets are connected to the rotating rod. The first motor is connected to the frame. The sixth sprocket is connected to the output shaft of the first motor. One end of the third chain is sleeved on the fifth sprocket, and the other end of the third chain is sleeved on the sixth sprocket. Both the fifth and sixth sprockets are engaged with the third chain.

[0018] By adopting the above technical solution, the first motor drives the sixth sprocket to rotate, which in turn drives the third chain to transmit. The third chain drives the fifth sprocket to rotate, and the rotating rod follows the fifth sprocket to rotate, thereby driving the two first sprockets to rotate, which in turn drives the two first chains to transmit synchronously. This facilitates the movement of the support frame, and the synchronous transmission of the two first chains improves the stability of the fabric roll transportation process.

[0019] Optionally, the frame is connected to a position detector, which is electrically connected to a controller. The controller is electrically connected to a first motor. The position detector is used to detect whether the support frame has reached the highest or lowest position. When the position detector detects that the support frame has reached the highest or lowest position, the controller controls the first motor to shut down.

[0020] By adopting the above technical solution and adding a position detector, when the support frame moves to the highest or lowest position, the controller controls the first motor to shut down, thereby stopping the transmission of the first chain, thus limiting the movement trajectory of the support frame.

[0021] Optionally, the frame is connected to a guide plate, which is used to guide the fabric roll from the unloading end of the second moving component to the loading end of the first moving component.

[0022] By adopting the above technical solution, when the fabric roll is fed to the first moving component, the fabric roll is placed on the moving frame, and the second moving component drives the moving frame to move. When the fabric roll approaches the feeding end of the first moving component, the moving frame moves to the end of the second chain. The second chain drives the moving frame to move and drives the fabric roll away from the moving frame and moves to the guide plate. The fabric roll moves along the guide plate and approaches the feeding end of the first moving component, which further facilitates the feeding of the fabric roll and further reduces labor costs.

[0023] Optionally, the support frame has a placement slot for placing the fabric roll, and one end of the placement slot has a first guide surface, which is used to guide the fabric roll into the placement slot.

[0024] By adopting the above technical solution, when the fabric roll is fed to the support frame, the fabric roll moves along the guide plate and approaches the support frame. The fabric roll contacts the first guide surface and enters the placement slot under the guidance of the first guide surface, making it more convenient for the fabric roll to enter the placement slot.

[0025] Optionally, the support frame is connected to a stop, which is used to prevent the fabric roll from leaving the placement slot.

[0026] By adopting the above technical solution and adding a stop block, the support frame is prevented from falling out of the placement slot as much as possible, thereby improving the stability of the connection between the support frame and the fabric roll.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During use, the fabric roll is placed on the support frame. The first moving component moves the support frame to the corresponding position according to the diameter of the fabric roll, so that the bottom of the fabric roll is away from the frame, reducing the friction between the fabric roll and the frame and causing wear on the fabric roll. In addition, the first moving component moves the support frame according to the diameter of the fabric roll, which can avoid the situation where the fabric roll is too high, resulting in a small contact area between the fabric and the first power roller shaft, affecting the stability of the fabric transport. This makes it easier to adapt to the installation height requirements of fabric rolls with different diameters.

[0029] 2. The rotating component drives the first sprocket to rotate, the first sprocket drives the first chain to transmit, which in turn drives the second sprocket to rotate, and the first chain drives the support frame to move, thereby facilitating the change of the height between the support frame and the fabric roll;

[0030] 3. When in use, when the fabric roll is placed on the moving frame, the drive unit drives the third sprocket to rotate, the third sprocket drives the second chain to drive the transmission, the second chain drives the fourth sprocket to rotate, and the moving frame follows the transmission of the second chain, thereby moving the moving frame and the fabric roll closer to the feeding end of the first moving component, which facilitates the feeding of the fabric roll and reduces labor costs.

The support frame 300 is connected to the first chain 210.

[0044] Reference Figure 3 A rotating component 800 is connected to the frame 100, which drives the first sprocket 220 to rotate. The rotating component 800 includes a third chain 810, a fifth sprocket 820, a sixth sprocket 830, and a first motor 840. A rotating rod 140 is rotatably connected to the frame 100, with its length direction aligned with that of the connecting rod 110.

The first motor 840 is connected to the frame 100, and the sixth sprocket 830 is connected to the output shaft of the first motor 840, with the central axis of the output shaft of the first motor 840 collinear with the central axis of the sixth sprocket 830. One end of the third chain 810 is fitted onto the fifth sprocket 820, and the other end is fitted onto the sixth sprocket 830. Both the fifth sprocket 820 and the sixth sprocket 830 are engaged with the third chain 810. Two first sprockets 220 are respectively fitted onto both ends of the rotating rod 140.

A connecting rod 110 is added to allow the two first sprockets 220 to rotate synchronously, thereby improving the stability of the support frame 300's movement.

[0045] Reference Figure 1 and Figure 4 The support frame 300 has a placement groove 310 for placing the fabric roll, and the placement groove 310 is arranged in an arc shape. A stop block 320 is connected to the end of the support frame 300 near the fabric spreading machine body, and the stop block 320 is positioned above the placement groove 310.

The bottom ends of the first guide surface 330 and the second guide surface 340 are close to each other and inclined.

[0046] Reference Figure 1The frame 100 is connected to a position detector 150, which includes two photoelectric sensors 151, located at the top and bottom of the first chain 210, respectively. The photoelectric sensors 151 are GS20SN type, electrically connected to a controller (a microcontroller). The first motor 840 is also electrically connected to the controller. The photoelectric sensors 151 detect whether the support frame 300 has reached the corresponding position. When the photoelectric sensor 151 detects that the support frame 300 has reached the corresponding position, the controller shuts down the first motor 840. The addition of the photoelectric sensor 151 and controller allows for the detection of whether the support frame 300 has reached the corresponding position, thereby limiting the movement trajectory of the support frame 300 and reducing the risk of damage caused by the support frame 300 colliding with the frame 100 when it moves below the first chain 210.

[0047] The implementation principle of a fabric transport device according to an embodiment of this application is as follows: In use, the fabric roll is placed on the loading platform 600. Simultaneously, a support frame 300 is positioned below the fabric roll. A second motor 740 is connected to an eighth sprocket 720, which rotates. The eighth sprocket 720 transmits power to the fourth chain 730, thereby driving the seventh sprocket 710 to rotate. The seventh sprocket 710 drives the connecting rod 110 to rotate, and the third sprocket 420 follows the connecting rod 110. The third sprocket 420 drives the second chain 410, which in turn drives the support frame 300 to move upwards, thus supporting the fabric roll and moving it. When the fabric roll reaches the top of the second chain 410, it moves to the guide plate 120 and along the guide plate 120 into the placement groove 310. When the fabric roll is placed in the placement slot 310, the first motor 840 drives the sixth sprocket 830 to rotate, causing the third chain 810 to transmit power. The third chain 810 drives the fifth sprocket 820 to rotate, which in turn drives the rotating rod 140 to rotate. The two first sprockets 220 follow the rotating rod 140, thereby driving the first chain 210 to transmit power. This causes the support frame 300 to move the fabric roll and move the bottom of the fabric roll away from the frame 100. Furthermore, the first moving component 200 moves the support frame 300 to different heights according to the different diameters of the fabric roll. This allows the transport device to adapt to the installation height requirements of fabric rolls of different diameters, minimizing friction between the bottom of the fabric roll and the frame 100, and reducing the contact area between the fabric and the first power roller due to excessively high installation, thus improving the stability of fabric transport.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
