Description

Technical Field

[0001] This utility model relates to the field of fabric processing, specifically to an active unwinding device for fabric. Background Technology

[0002] Dyeing and finishing is a chemical and physical processing of fabrics under certain process conditions, using dyes, chemicals and auxiliaries on specialized equipment. Before the dyeing and finishing process, the rolled fabric needs to be unwound, and the equipment used is called an unwinding machine.

[0003] A traditional unwinding machine includes a frame and a material rack. The material rack is trough-shaped, and two parallel drive rollers are set at the bottom of the material rack. Both ends of the drive rollers are rotatably engaged with the side wall of the material rack through bearings. The side wall of the material rack has a sliding groove along the width of the material rack, and the bearing is located in the sliding groove and slidably engaged with it. The drive mechanism drives the drive rollers to rotate, thereby driving the fabric to perform the unwinding operation.

[0004] In existing unwinding machines, the fabric is usually placed on a rack and driven by a drive mechanism to rotate the transmission rollers, thereby driving the fabric to unwind. However, due to the weight of the fabric and the friction of materials such as denim, canvas and nylon, the fabric may get stuck and unable to unwind. This can affect the unwinding efficiency or even cause the machine to malfunction. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an active unwinding device for fabric to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an active fabric unwinding device, comprising a mounting frame, a controller for controlling the operation of the device mounted on the mounting frame, a transmission roller mounted inside the mounting frame, a first fixing block and a second fixing block on the mounting frame, a rotating rod rotatably disposed between the first fixing block and the second fixing block, a first rotating roller sleeved on the outer surface of the rotating rod, a rotary motor disposed on one side of the first fixing block, a placement frame disposed inside the mounting frame, and the placement frame is mounted inside the mounting frame via connecting shafts at both ends, a swaying mechanism for driving the placement frame to sway left and right is mounted on the mounting frame, the swaying mechanism includes a drive motor, the output end of the drive motor is connected to the rotating shaft, a drive rod is disposed on the rotating shaft, and a connecting rod is disposed inside the drive rod, a sleeve is connected to the end of the connecting rod away from the drive rod, a fixing rod is disposed at the bottom end of the placement frame, and the sleeve is sleeved on the outer surface of the fixing rod, a swinging component is mounted on the mounting frame, the swinging component facilitates the folding operation of the unwound fabric, and a placement component and a collection component are respectively disposed on both sides of the mounting frame.

[0007] By adopting the above technical solution, the fabric is placed on the pallet, and one end passes through the transmission roller and the first rotating roller to finally reach the swing assembly. The drive mechanism drives the fabric to fold back and forth, which facilitates the unwinding of the fabric at the rear end. At the same time, the drive motor starts, driving the rotating shaft to rotate. The drive rod set on the rotating shaft then rotates, driving the connecting rod set on the drive rod to rotate. Since the connecting rod is sleeved on the fixed rod at the end, when the drive rod rotates, it causes the placement frame connected to the fixed rod to sway left and right, preventing jamming due to excessive gravity or friction during the unwinding operation.

[0010] The present invention is further configured such that the placement component includes a tray disposed on one side of the mounting frame, the tray having a groove, an arc-shaped plate being mounted on the groove, and a pushing mechanism being disposed within the groove.

[0011] Preferably, the fabric is placed on a pallet and one end of the fabric is threaded through the mounting frame. When the equipment starts running, the fabric is pushed into the placement frame by a pushing mechanism, which facilitates the unwinding operation.

[0012] The present invention is further configured such that the pushing mechanism includes a rotating shaft disposed on an arc-shaped plate, the end of the rotating shaft being rotatably connected to an arc-shaped push plate, an electric push rod being disposed in the groove, a hinge block being slidably disposed at the rear end of the arc-shaped push plate, and the output end of the electric push rod being hinged to the hinge block.

[0013] Preferably, the electric push rod is activated to push the hinge block, which is hinged at the output end, upward. The hinge block is slidably positioned at the rear end of the arc-shaped push plate. As the electric push rod rises, it drives the arc-shaped push plate upward, pushing the fabric placed on it into the placement frame for easy unwinding.

[0014] The present invention is further configured such that the swing assembly includes a mounting rod disposed on a mounting frame, a second rotating roller is sleeved on the outer surface of the mounting rod, mounting plates are connected to both ends of the mounting rod, a first limiting plate and two second limiting plates are respectively disposed between the mounting plates, and a driving mechanism for driving the mounting plates to swing is mounted on the mounting frame.

[0015] Preferably, the mounting plate is swung by the de-driving mechanism, causing the fabric that is limited by the first limiting plate and the second limiting plate to fold back and forth, thereby facilitating the unwinding of the rear end of the fabric to be folded.

[0016] The present invention is further configured such that the driving mechanism includes a turntable disposed on one side of the mounting bracket, the turntable being rotatably connected to one end of a movable rod, the other end of the movable rod being rotatably connected to one of the mounting plates, and the movable rod and the rotating rod being connected by a transmission component.

[0017] Preferably, when the rotary motor drives the rotating rod to rotate, the transmission component drives the turntable to rotate, and the movable rod connected to the turntable drives the mounting plate to swing, thereby facilitating the unwinding and rear-end folding and storage operation.

[0018] The present invention is further configured such that the transmission component includes a belt sleeved on the outer surface of the rotating rod and the turntable, and the outer surface of the rotating rod and the turntable is provided with a pulley that cooperates with the belt.

[0019] Preferably, pulleys are provided on the outer surfaces of both the turntable and the rotating rod, which facilitates the installation of belts and transmits the power provided by the rotary motor to the turntable.

[0020] The present invention is further configured such that the collecting component includes a collecting frame, and the bottom of the collecting frame is provided with multiple movable parts.

[0021] Preferably, the collection box facilitates the collection of the unwound fabric, making subsequent operations easier for staff, and the movable component allows for easy movement of the collection box.

[0022] The present invention is further configured such that the movable component includes a movable wheel, and the movable wheel is a self-locking universal wheel.

[0023] Preferably, multiple moving wheels are provided to facilitate the movement of the collection frame, making it convenient to transport the fabric to the workshop for subsequent cutting or other processing operations after unwinding.

[0024] The present invention is further provided that the bottom of the mounting bracket is provided with a protective pad, and the protective pad is made of rubber.

[0025] Preferably, the protective pad is used to increase the friction between the device and the ground, thereby enhancing the stability of the equipment. Rubber has strong elasticity and can effectively reduce shock.

[0026] In summary, the present invention has the following main advantages:

[0027] This invention achieves the purpose of swaying the fabric placed in the placement frame from side to side by setting up a swaying component. When the drive motor is started, the rotating shaft is rotated, and the drive rod set on the rotating shaft rotates accordingly, which in turn drives the connecting rod set on the drive rod to rotate. Since the connecting rod is sleeved on the fixed rod through the end sleeve, the placement frame connected to the fixed rod is swayed from side to side when the drive rod rotates, preventing the unwinding operation from getting stuck due to excessive gravity or friction.

[0028] This invention, by incorporating a swing assembly, facilitates the folding of unwound fabric, reducing the workload for subsequent workers. One end of the fabric passes through the transmission roller and the first rotating roller, finally reaching the swing assembly. The fabric is then placed on one end of the first rotating roller, interlacing in an S-shape between the first limiting plate and the two second limiting plates. A controller starts a rotary motor, which in turn drives the first rotating roller to rotate. As the rotary motor drives the rotating rod to rotate, it simultaneously drives the turntable to rotate via a transmission component. The rotating rod connected to the turntable causes the mounting plate to swing, allowing the fabric, which is limited by the first and second limiting plates, to fold back and forth, thus facilitating the folding of the unwound fabric at the rear end.

A transfer roller 103 is installed inside the mounting frame 100. A first fixing block 300 and a second fixing block 301 are provided on the mounting frame 100. A rotating rod 303 is rotatably connected between the first fixing block 300 and the second fixing block 301. A first rotating roller 304 is sleeved on the outer surface of the rotating rod 303. A rotary motor 302 is provided on one side of the first fixing block 300. A placement frame 600 is provided inside the mounting frame 100, and the placement frame 600 is mounted inside the mounting frame 100 via connecting shafts 601 at both ends. A swaying mechanism is installed on the mounting frame 100 to drive the placement frame 600 to sway left and right. The swaying mechanism includes a drive motor 607, the output end of which is connected to a rotating shaft 606. A drive rod 605 is provided on the rotating shaft 606, and a connecting rod 604 is provided inside the drive rod 605. The connecting rod 604 is located away from the drive rod 606. One end of the 05 is connected to the sleeve 603. The bottom end of the placement frame 600 is provided with a fixed rod 602, and the sleeve 603 is sleeved on the outer surface of the fixed rod 602. The placement frame 600 is installed in the mounting frame 100 through the connecting shaft 601. The drive motor 607 is started and slowly drives the rotating shaft 606 to rotate, so that the drive rod 605 set on the rotating shaft 606 rotates accordingly, thereby driving the connecting rod 604 set on the drive rod 605 to rotate. Since the connecting rod 604 is sleeved on the fixed rod 602 through the sleeve 603 at the end, when the drive rod 605 rotates, it drives the placement frame 600 connected to the fixed rod 602 to rotate. The placement frame 600 swings left and right about the connecting shaft 601 in a circle to prevent jamming due to excessive weight or friction during the unwinding operation. The mounting frame 100 is equipped with a swing component, which facilitates the folding operation of the unwound fabric.

A hinge block 206 is slidably provided at the rear end of the arc-shaped push plate 204. The output end of the electric push rod 205 is hinged to the hinge block 206.

[0046] Since the arc-shaped push plate 204 is rotatably mounted on the rotating shaft 203, the electric push rod 205 is activated to push the hinge block 206, which is hinged at the output end, upward. The hinge block 206 is slidably mounted at the rear end of the arc-shaped push plate 204. As the electric push rod 205 rises, it drives the arc-shaped push plate 204 upward, pushing the fabric placed on it into the placement frame 600, which facilitates the unwinding operation.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The swing assembly includes a mounting rod 400 mounted on a mounting frame 100.

A first limiting plate 403 and two second limiting plates 404 are respectively provided between the mounting plates 402. A drive mechanism for driving the mounting plates 402 to swing is mounted on the mounting frame 100.

[0048] The drive mechanism drives the mounting plate 402 to swing, causing the fabric, which is limited by the first limiting plate 403 and the second limiting plate 404, to fold back and forth. This facilitates the unwinding of the fabric at the rear end, saving time for manual collection, improving efficiency, and making subsequent operations easier.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The driving mechanism includes a turntable 500 disposed on one side of the mounting bracket 100. The turntable 500 is rotatably connected to one end of a movable rod 502, and the other end of the movable rod 502 is rotatably connected to one of the mounting plates 402. The movable rod 502 and the rotating rod 303 are connected by a transmission component.

[0050] When the rotary motor 302 drives the rotating rod 303 to rotate, it drives the turntable 500 to rotate through the transmission component. The movable rod 502 connected to the turntable 500 drives the mounting plate 402 to swing, which facilitates the unwinding and folding of the rear end for storage.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The transmission component includes a belt 501 sleeved on the outer surface of the rotating rod 303 and the turntable 500, and the outer surface of the rotating rod 303 and the turntable 500 is provided with a pulley that cooperates with the belt 501.

[0053] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The mounting bracket 100 has a protective pad 101 at the bottom, and the protective pad 101 is made of rubber.

[0054] The protective pad 101 is designed to increase friction with the ground, thereby enhancing the stability of the equipment. Rubber has strong elasticity and can effectively absorb shocks.

[0055] Second embodiment:

[0056] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The collection component includes a collection frame 700, and the bottom of the collection frame 700 is provided with multiple movable parts.

[0057] The collection box 700 facilitates the collection of the unwound fabric, making subsequent operations easier for staff. The movable component allows for easy movement of the collection box 700.

[0058] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The movable component includes a movable wheel 701, and the movable wheel 701 is a self-locking universal wheel.

[0059] By setting multiple movable wheels 701, the collection box 700 can be moved easily, making it convenient to transport the fabric to the workshop for subsequent cutting or other processes after unwinding. The self-locking casters can be moved to the required position and then fixed to prevent displacement during use.

[0060] In practical operation, the fabric is placed on the pallet 200, with one end passing through the transmission roller 103 and the first rotating roller 304 to reach the swing assembly. The fabric is positioned at one end of the first rotating roller 304, interlacing in an S-shape between the first limiting plate 403 and the two second limiting plates 404. The controller 102 starts the rotary motor 302, which drives the first rotating roller 304 to rotate. Simultaneously, the rotary motor 302 drives the rotating rod 303 to rotate, which in turn drives the turntable 500 to rotate via a transmission component. The movable rod 502 connected to the turntable 500 rotates the mounting plate 402, causing it to swing. This folds the fabric, which is limited by the first and second limiting plates 403 and 404, back and forth, facilitating the unwinding process. When the rotary motor 302 starts the unwinding operation, the electric push rod 205 is activated. The hinge block 206 at the output end is upward-facing, and the hinge block 206 is slidably positioned at the rear end of the arc-shaped push plate 204. As the electric push rod 205 rises, it drives the arc-shaped push plate 204 upward, pushing the fabric placed on it into the placement frame 600 for easy unwinding. The drive motor 607 starts and slowly drives the rotating shaft 606 to rotate, causing the drive rod 605 on the rotating shaft 606 to rotate as well. This, in turn, drives the connecting rod 604 on the drive rod 605 to rotate. Since the connecting rod 604 is sleeved on the fixed rod 602 through the sleeve 603 at its end, when the drive rod 605 rotates, it drives the placement frame 600 connected to the fixed rod 602 to rotate. The placement frame 600 sways left and right around the connecting shaft 601 to prevent jamming due to excessive gravity or friction during the unwinding operation.
