Description

Technical Field

[0001] This application relates to the field of unwinding machines, and more particularly to a fabric unwinding machine with a movable feed rack. Background Technology

[0002] Dyeing and finishing is an indispensable part of the textile industry. Specialized equipment is used to chemically and physically process fabrics, giving them specific colors, textures, and functionalities. In this process, the fabric unwinding machine is a key piece of equipment, used to unwind rolled fabric for subsequent processing.

[0003] Chinese Patent CN218560563U discloses a knitted fabric unwinding device, including a mounting frame. A placement groove is fixedly installed on one side of the bottom of the mounting frame, an unwinding mechanism is fixedly installed on the top of the mounting frame, a lifting mechanism is fixedly installed on the other side of the bottom of the mounting frame, a take-up rack is installed on the top of the lifting mechanism, and a control panel is fixedly installed on the side of the mounting frame. Through the provided unwinding mechanism, when the fabric is placed inside the placement groove, it is wound around the surface of the conveyor roller and then wound around the surface of the unwinding roller again. The drive motor is controlled to rotate, and the drive motor drives the unwinding roller to rotate, which in turn drives the drive wheel installed on the other end of the unwinding roller to rotate together. The drive wheel drives the conveyor roller installed on the surface of the support rod to rotate together through the belt. The conveyor roller will carry the fabric to the unwinding roller. The unwinding roller and the conveyor roller rotate synchronously, causing the fabric to be unwound at a uniform speed.

[0004] Regarding the aforementioned technologies, in actual operation, due to space limitations in the production site, it is usually impossible to stack fabric rolls next to the unwinding machine, resulting in a certain distance between the area where fabric rolls are stacked and the unwinding machine. When feeding fabric rolls, operators need to move the fabric rolls to the placement rack one by one. Since the fabric rolls are relatively heavy, the process of moving the fabric rolls to the placement rack is quite laborious, thus consuming a large amount of labor costs. Utility Model Content

[0005] To reduce the labor costs associated with feeding fabric rolls, this application provides a fabric unwinding machine with a movable feeding rack.

[0006] The fabric unwinding machine with a movable feeding rack provided in this application adopts the following technical solution:

[0007] A movable fabric unwinding machine includes a frame, an unwinding assembly, and a placement rack. The unwinding assembly is connected to the frame. The bottom of the placement rack is connected to four rollers, which are distributed in a rectangular array along the placement rack. The frame is connected to two connecting plates. The length direction of the connecting plates is consistent with the width direction of the placement rack. The two connecting plates are spaced apart along the length direction of the placement rack. The two connecting plates are provided with connecting channels for placing the placement rack. A locking plate is connected to the side of the connecting plate near the connecting channel. The length direction of the locking plate is consistent with the length direction of the placement rack. The locking plate is slidably connected to the connecting plate along its length direction and contacts the placement rack.

[0008] By adopting the above technical solution, during use, the locking plate moves along the length of the placement frame, thereby moving the locking plate away from the connecting channel. This facilitates the removal of the placement frame from the connecting channel. The placement frame is then moved to the area where the fabric rolls are stacked. After the fabric rolls are transported into the placement frame, the placement frame is moved, causing the fabric rolls to move and move closer to the machine frame. When the placement frame is embedded in the connecting channel, the locking plate moves along the length of the placement frame, causing one side of the locking plate to contact the placement frame. This ensures that the placement frame is stably set in the connecting channel, thereby reducing the labor costs required for fabric roll feeding.

[0009] Optionally, a movable groove is provided at one end of the connecting plate near the connecting channel. The depth direction of the movable groove is consistent with the length direction of the placement rack. A first spring is connected inside the movable groove. The length direction of the first spring is consistent with the length direction of the placement rack. One end of the first spring is connected to the inner wall of the movable groove, and the other end of the first spring is connected to a locking plate. The locking plate is slidably connected to the movable groove along its length direction. When the locking plate is embedded in the movable groove, the first spring is compressed and deformed.

[0010] By adopting the above technical solution, during unwinding, the locking plate contacts the placement frame. When a new roll of fabric needs to be moved, the locking plate is moved along the length of the placement frame, causing it to embed into the moving groove. This causes the locking plate to compress the first spring, which deforms, thus facilitating the movement of the placement frame away from the connecting channel. After the roll of fabric is moved to the placement frame, the placement frame is moved closer to the connecting channel. The locking plate is then moved along its length, causing it to embed into the moving groove, thus facilitating the embedding of the placement frame into the connecting channel. Once the placement frame is embedded into the connecting channel, the operator releases the locking plate, the first spring returns to its shape, and pushes the locking plate. The locking plate moves along its length along the placement frame, thus bringing it into contact with the placement frame, thereby ensuring the placement frame is stably positioned within the connecting channel.

[0011] Optionally, a sliding hole is provided on the inner wall of one end of the moving groove along the length direction of the connecting plate. The length direction of the sliding hole is consistent with the length direction of the placement rack. A connecting rod is connected to one end of the locking plate along the length direction of the connecting plate. The length direction of the connecting rod is consistent with the length direction of the connecting plate. The connecting rod passes through the sliding hole along its length direction and is slidably connected to the sliding hole along the length direction of the connecting plate. A locking component is connected to the connecting rod. The locking component is used to lock the connecting rod in the sliding hole. When the connecting rod is locked in the sliding hole, the locking plate is embedded in the moving groove.

[0012] By adopting the above technical solution, the connecting rod is pushed along the length of the placement rack, so that the connecting rod slides into the sliding hole along the length of the placement rack. This causes the locking plate to move with the connecting rod and is driven to embed into the moving groove. The locking component locks the connecting rod into the sliding hole, so that the locking plate is stably set in the moving groove, thereby facilitating the placement rack to be embedded into or moved away from the connection channel.

[0013] Optionally, the sliding hole includes a first hole and a second hole. The length direction of the first hole is consistent with the length direction of the placement rack, and the length direction of the second hole is consistent with the vertical direction. The second hole is connected to the end of the first hole away from the connecting channel. The locking assembly includes a positioning plate and a second spring. The positioning plate is rotatably sleeved on the end of the connecting rod away from the locking plate. The length direction of the second spring is consistent with the length direction of the connecting rod. The second spring is sleeved on the connecting rod. One end of the second spring is connected to the positioning plate, and the other end of the second spring is connected to the locking plate. The positioning plate is slidably connected to the connecting rod along the length direction of the connecting rod. The positioning plate is slidably connected to the first hole along the length direction of the placement rack. When the positioning plate contacts the inner wall of the second hole, the locking plate is embedded in the moving groove.

[0014] By adopting the above technical solution, when the placement rack is embedded in or away from the connecting channel, the positioning plate moves along the length of the placement rack, so that the positioning plate and the connecting rod slide in the first hole along the length of the placement rack. This drives the locking plate to move along the length of the placement rack, so that the locking plate is embedded in the moving groove. When one end of the positioning plate is embedded in the second hole, the positioning plate is pulled along the length of the connecting rod, so that the second spring is stretched and deformed, and the positioning plate moves away from the sliding hole. After the positioning plate moves away from the sliding hole, the positioning plate moves along the length of the placement rack, so that the connecting rod is embedded in the second hole. The positioning plate is rotated and released, the second spring returns to its shape and drives the positioning plate to be embedded in the second hole. The side wall of the positioning plate contacts the inner wall of the second hole, so that the positioning plate is stably connected in the second hole, and thus drives the locking plate to be stably connected in the moving groove. This facilitates the placement rack being embedded in or away from the connecting channel.

[0015] Optionally, the locking plate has a guide surface along the length of the connecting plate and away from the connecting channel. The guide surface is inclined and facilitates the locking plate to be embedded in the moving groove.

[0016] By adopting the above technical solution, when installing the placement rack, the guide surface contacts the placement rack and is guided by the guide surface. The locking plate is embedded in the moving groove, which facilitates the placement rack being embedded in the connecting channel.

[0017] Optionally, the frame is connected to guide rails, the length direction of which is consistent with the length direction of the connecting plate. There are two guide rails, which are spaced apart along the length direction of the placement frame. The guide rails are located in the connecting channel, and a guide plate is connected to one end of the guide rail along its length direction and near the locking plate.

[0018] By adopting the above technical solution and adding guide rails, the movement direction of the placement rack is guided, making it easier for the placement rack to be embedded into the connecting push.

[0019] Optionally, a handle is attached to one end of the shelf along its width.

[0020] By adopting the above technical solution and adding handles, it is easier for operators to move and place the rack.

[0021] Optionally, a support ring is connected to one end of the placement rack along its width direction. The support ring is connected to the top of the placement rack. The handle is slidably connected to the support ring in the vertical direction. A first magnetic block is connected to the bottom of the handle. A second magnetic block is connected to the support ring. When the support ring and the bottom of the handle are close to each other, the first magnetic block and the second magnetic block attract each other.

[0022] By adopting the above technical solution, when moving the shelf, the support ring and the bottom of the handle are connected to the second magnetic block through the first magnetic block. When the shelf is embedded in the connecting channel, the handle is pushed in the vertical direction, so that the first magnetic block moves away from the second magnetic block, thereby reducing the space required by the shelf during use.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During use, the locking plate moves along the length of the placement frame to move it away from the connecting channel, making it easier to remove the placement frame from the connecting channel. Move the placement frame to the area where the fabric rolls are stacked, and after the fabric rolls are transported into the placement frame, move the placement frame. The placement frame moves the fabric rolls and brings them closer to the machine frame. When the placement frame is embedded in the connecting channel, the locking plate moves along the length of the placement frame and makes one side of the locking plate contact the placement frame, so that the placement frame is stably set in the connecting channel, thereby reducing the labor cost required for fabric roll feeding.

[0025] 2. Push the connecting rod along the length of the placement rack so that the connecting rod slides into the sliding hole along the length of the placement rack, so that the locking plate moves with the connecting rod and is driven to embed into the moving groove. The locking component locks the connecting rod into the sliding hole, so that the locking plate is stably set in the moving groove, thereby facilitating the placement rack to be embedded into or moved away from the connection channel.

[0026] 3. When moving the shelf, the support ring and the bottom of the handle are connected to the second magnetic block through the first magnetic block. After the shelf is inserted into the connecting channel, push the handle vertically to move the first magnetic block away from the second magnetic block, thereby reducing the space required by the shelf during use.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a fabric unwinding machine with a movable material rack. (See also...) Figure 1and Figure 2 A fabric unwinding machine with a movable material rack includes a frame 100, an unwinding assembly 200, and a placement rack 300. The unwinding assembly 200 is connected to the frame 100. The placement rack 300 is horizontally positioned, and four rollers 310 are connected to its bottom, arranged in a rectangular array at the bottom of the placement rack 300. Two connecting plates 400 are connected to the frame 100. The connecting plates 400 are located below the unwinding assembly 200, with their length direction aligned with the width direction of the placement rack 300. One end of the connecting plate 400 is connected to the frame 100 along its length direction.

[0036] Reference Figure 1 and Figure 3 Two connecting plates 400 are spaced apart along the length of the placement rack 300, and the two connecting plates 400 are provided with connecting channels 410 for placing the placement rack 300. A locking plate 500 is slidably connected to one end of the connecting plate 400 away from the frame 100 along its length. The locking plate 500 is slidably connected to the connecting plate 400 along the length of the placement rack 300, and is in contact with the placement rack 300 during use. During use, the placement rack 300 is placed in the connecting channel 410, and the locking plate 500 is in contact with the placement rack 300. When the placement rack 300 is disassembled, the locking plate 500 is moved along the length of the placement rack 300, so that the locking plate 500 is away from the connecting channel 410. This facilitates the removal of the placement rack 300 from the connecting channel 410 and the movement of the placement rack 300 to the area where the fabric rolls are stacked, thereby facilitating the feeding of the fabric rolls and reducing the labor costs required for feeding the fabric rolls.

[0037] Reference Figure 1 The unwinding assembly 200 includes an unwinding roller 210 and a second motor 220. The length direction of the unwinding roller 210 is consistent with the length direction of the placement frame 300. The unwinding roller 210 is rotatably connected to the frame 100. The second motor 220 is connected to the frame 100 and is used to drive the unwinding roller 210 to rotate.

[0038] Reference Figure 1 and Figure 4 The placement rack 300 has a handle 320 connected to one end along its width away from the frame 100. The handle 320 includes a first rod 321 and a second rod 322. The length direction of the first rod 321 is consistent with the vertical direction. There are two first rods 321, which are spaced apart along the length direction of the placement rack 300. The length direction of the second rod 322 is consistent with the length direction of the placement rack 300. The two ends of the second rod 322 are respectively connected to the two first rods 321, and the second rod 322 is connected to the top of the first rod 321.

[0039] Reference Figure 1 and Figure 4A support ring 330 is connected to the end of the placement rack 300 along its width direction away from the frame 100. The support ring 330 is horizontally positioned and connected to the top of the placement rack 300. Two support rings 330 are provided, spaced apart along the length of the placement rack 300. Each support ring 330 corresponds to a first rod 321, and the support ring 330 is slidably sleeved on the outside of the first rod 321. The central axis of the first rod 321 is collinear with the central axis of the support ring 330. A mounting ring 323 is sleeved on the bottom end of the first rod 321, and the top of the mounting ring 323 contacts the bottom of the support ring 330. A first magnet 324 is embedded in the top of the mounting ring 323, and a second magnet 331 is embedded in the bottom of the support ring 330. When the support ring 330 and the mounting ring 323 approach each other, the first magnet 324 and the second magnet 331 attract each other. The handle 320 is slidably connected to the shelf 300 in the vertical direction to reduce the space occupied by the shelf 300 during use.

[0040] Reference Figure 1 and Figure 2 The frame 100 is connected to two guide rails 110, which are spaced apart along the length of the placement frame 300. The two guide rails 110 are located within the connecting channel 410, and the length of the guide rails 110 is consistent with the length of the connecting plate 400. Rollers 310 are rotatably connected to the guide rails 110. Guide plates 111 are connected to both ends of the guide rails 110 along their width. The guide plates 111 are located along the length of the guide rails 110 and close to the locking plate 500. One end of the guide plate 111 is connected to the guide rail 110, and the guide plate 111 is inclined towards the side away from the other guide plate 111.

[0041] Reference Figure 1 and Figure 5 A movable groove 420 is formed at one end of the connecting plate 400 near the connecting channel 410. The depth of the movable groove 420 is consistent with the length of the placement rack 300. Two first springs 421 are connected inside the movable groove 420. The length of the first springs 421 is consistent with the length of the placement rack 300. The two first springs 421 are vertically spaced apart inside the movable groove 420. One end of the first spring 421 is connected to the inner wall of the movable groove 420 along its length, and the other end is connected to the locking plate 500. The locking plate 500 is slidably connected to the movable groove 420 along its length. The locking plate 500 has a guide surface along the length of the connecting plate 400 and on the side away from the connecting channel 410. The end of the guide surface away from the first spring 421 is inclined towards the side closer to the connecting channel 410. The locking plate 500 is moved along the length of the placement rack 300 so that it is embedded in the moving groove 420, causing the first spring 421 to be compressed and deformed, thereby facilitating the placement rack 300 to be embedded in or moved away from the connecting channel 410.

[0042] Reference Figure 1 and Figure 6 A sliding hole 430 is provided on the inner wall of one end of the moving groove 420 along the length direction of the connecting plate 400. The sliding hole 430 is located on the inner wall of the moving groove 420 away from the frame 100. The sliding hole 430 includes a first hole 431 and a second hole 432. The length direction of the first hole 431 is consistent with the length direction of the placement rack 300, and the length direction of the second hole 432 is consistent with the vertical direction. The end of the first hole 431 along its length direction and away from the connecting channel 410 communicates with the second hole 432. A connecting rod 510 is connected to the end of the locking plate 500 near the sliding hole 430. The length direction of the connecting rod 510 is consistent with the length direction of the connecting plate 400. The connecting rod 510 passes through the sliding hole 430 along its length direction and is slidably connected in the first hole 431 and the second hole 432 along the length direction of the connecting plate 400.

[0043] Reference Figure 1 and Figure 6 The connecting rod 510 is connected to a locking assembly 600, which is used to lock the connecting rod 510 in the sliding hole 430. A sleeve 511 is slidably fitted on the end of the connecting rod 510 along its length and away from the locking plate 500, and the central axis of the sleeve 511 is collinear with the central axis of the connecting rod 510.

[0044] Reference Figure 1 and Figure 6 The locking assembly 600 includes a positioning plate 610 and a second spring 620. The positioning plate 610 is rotatably sleeved on the sleeve 511 and slidably connected to the first hole 431 along the length of the connecting rod 510. A pull rod 611 is connected to the end of the positioning plate 610 away from the locking plate 500, and the length direction of the pull rod 611 is consistent with the length direction of the connecting rod 510. The length direction of the second spring 620 is consistent with the length direction of the connecting rod 510. The second spring 620 is sleeved on the connecting rod 510, and one end of the second spring 620 along its length direction is connected to the end of the sleeve 511 near the locking plate 500, while the other end of the second spring 620 is connected to the locking plate 500. When the positioning plate 610 moves away from the sliding hole 430, the second spring 620 is stretched and deformed. When the positioning plate 610 is embedded in the second hole 432 and in contact with the inner wall of the second hole 432, the locking plate 500 is embedded in the moving groove 420. The positioning plate 610 is moved along the length of the placement rack 300, thereby driving the locking plate 500 to be embedded in the moving groove 420. After one end of the positioning plate 610 is embedded in the second hole 432, the positioning plate 610 is pulled along the length of the connecting rod 510 and rotated so that the positioning plate 610 is embedded in the second hole 432, and the side wall of the positioning plate 610 contacts the inner wall of the second hole 432, so that the positioning plate 610 is stably set in the second hole 432, thereby making the locking plate 500 stably set in the moving groove 420, so as to facilitate the placement rack 300 to be embedded in or moved away from the connecting channel 410.

[0045] The implementation principle of a movable fabric unwinding machine with a material rack in this embodiment is as follows: When the fabric roll is fed, the pull rod 611 is pulled along the length of the placement rack 300, thereby driving the positioning plate 610 and the connecting rod 510 to move. The locking plate 500 moves with the connecting rod 510, so that the locking plate 500 is embedded in the moving groove 420. When one end of the positioning plate 610 is embedded in the second hole 432, it is pulled along the length of the connecting rod 510, so that the positioning plate 610 is away from the first hole 431, and the second spring 620 is stretched, causing the second spring 620 to deform. When the positioning plate 610 is away from the first hole 431, the positioning plate 610 is rotated, so that the positioning plate 610 is set vertically, and the second spring 620 returns to its deformation, driving the positioning plate 610 to be embedded in the second hole 432, thereby making the positioning plate 610 stably connected in the second hole 432, and making the locking plate 500 stably set in the moving groove 420. After the locking plate 500 is embedded in the moving slot 420, it is easy for the placement rack 300 to be moved away from the connecting channel 410, so that the operator can move the placement rack 300 to the area where the fabric rolls are stacked, and thus the operator can easily move the fabric rolls into the placement rack 300, reducing the labor cost required when feeding the fabric rolls.

[0046] 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.
