Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric rolling device for garment processing. Background Technology

[0002] Fabric unwinding devices for garment processing are equipment used in the textile and garment manufacturing industry. They are mainly used for the orderly winding or unwinding of fabrics. Such devices can ensure that the fabric can be smoothly unwound or rolled up without wrinkles during cutting, printing, dyeing or other processes.

[0003] Chinese Patent Publication No. CN221739349U, published on 20240920, discloses a rolling device for fabric used in garment manufacturing, including a base device, a flattening device in front of the base device, and a fixing device in the rear of the base device; the fixing device includes a shell, an inner liner installed in the middle of the shell, a valve installed on one side of the inner liner, the valve passing through the shell, and a plurality of fixing blocks evenly arranged on the outer circumference of the inner liner, the fixing blocks being slidably connected to the shell.

[0004] Existing fabric winding and unwinding devices, such as those described above, use a second motor to drive the opening and closing plate to rotate 90 degrees, opening one side of the fixing device to facilitate the placement of the take-up roller. After the take-up roller is inserted into the center of the outer casing, the bracket supports the second motor to drive the opening and closing plate to reset. The opening and closing plate then drives the rotating buckle to engage in the slot, providing support to the right end of the rotating shaft. Furthermore, the rotating buckle, which rotates around the opening and closing plate, does not affect the rotation of the shaft. However, in practical implementation, the fixed-point rotating opening and closing plate often fails to allow the rotating buckle to be quickly and completely inserted into the slot. Therefore, there is an urgent need to propose a corresponding fabric winding and unwinding device for garment processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric rolling device for garment processing in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fabric winding and unwinding device for garment processing includes a base and a fabric guiding assembly integrated on the top of the base. A driving component is fixedly connected to the top of the base via a base frame. A rotating cylinder is fixedly connected to the output end of the driving component. A boss is fixedly connected to the outer wall of the rotating cylinder. A rotating rod is rotatably connected between the rotating cylinder and the boss. An inner expansion seat and a pushing assembly for pushing the inner expansion seat are integrated between the rotating rod and the rotating cylinder. A support seat is detachably connected to the top of the support base. The outer side of the support seat is rotatably engaged with the boss via a connecting assembly.

[0008] Preferably, the support has an L-shaped structure, and the horizontal end of the support is fixedly connected to the top of the base by a locking rod.

[0009] Preferably, the connecting assembly includes a connecting sleeve that is rotatably engaged with the outer wall of the support via a bearing. The connecting sleeve is fitted onto the outside of the boss, and a fastening rod is screwed onto the top of the connecting sleeve. The open end of the fastening rod abuts against the outer wall of the boss.

[0010] Preferably, a rubber pad is fixedly connected to the inner wall of the connecting sleeve, and the rubber pad abuts against the outer wall of the rotating rod.

[0011] Preferably, the pushing assembly includes two sets of movable seats, and the outer wall of the rotating rod is screwed to the inner wall of the two sets of movable seats through two sets of opposite threaded grooves. Each set of the outer wall of the rotating rod is hinged with a push rod, and the open end of each set of push rods is hinged to the outer wall of the inner expansion seat.

[0012] Preferably, the guiding assembly includes a roller and a vertical rod that are fixedly connected, a bottom sleeve is fixedly connected to the top of the base, and a spring is fixedly connected between the bottom of the vertical rod and the inner wall of the bottom sleeve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the fabric roll is placed outside the rotating drum, the rotating rod is rotated, and the pushing component drives multiple sets of inner expansion seats to expand outward until the outer walls of the multiple sets of inner expansion seats are tightly fitted with the inner wall of the roll, thereby achieving the rotation and fixing of the roll.

[0015] 2. In this application, after the connecting sleeve is fitted onto the outer wall of the boss and fixed by the fastening rod, the rubber pad on the inner wall of the connecting sleeve will be in contact with the outer wall of the open end of the rotating rod. The friction between the rubber pad and the rotating rod can limit the axial deflection of the rotating rod during the rotation of the rotating cylinder, thereby ensuring the stability of the fabric winding and unwinding device for garment processing.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A fabric winding and unwinding device for garment processing includes a base 1 and a fabric guiding assembly integrated on the top of the base 1. A driving component 3 is fixedly connected to the top of the base 1 via a base frame 2. A rotating cylinder 4 is fixedly connected to the output end of the driving component 3. A boss 15 is fixedly connected to the outer wall of the rotating cylinder 4. A rotating rod 16 is rotatably connected between the rotating cylinder 4 and the boss 15. An inner expansion seat 5 and a pushing assembly for pushing the inner expansion seat 5 are integrated between the rotating rod 16 and the rotating cylinder 4. A support 6 is detachably connected to the top of the support 6. The outer side of the support 6 is rotatably engaged with the boss 15 via a connecting assembly.

[0025] The fabric roll is placed outside the rotating drum 4. The rotating rod 16 is rotated to push the component to expand the multiple sets of inner expansion seats 5 outward until the outer walls of the multiple sets of inner expansion seats 5 are tightly fitted with the inner wall of the roll, thereby fixing the rotating drum 4 and the roll. Then, the movable support 6 is moved so that the connecting sleeve 8 is fitted onto the outer wall of the protrusion 15. The support 6 is then fixed to the base 1. The connecting sleeve 8 and the protrusion 15 are then fixed by the fastening rod 9. The driving component 3 drives the roll to rotate through the rotating drum 4, and the connecting sleeve 8 rotates with the support 6 through the bearing 14, thereby achieving stable fabric winding and unwinding.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the support 6 has an L-shaped structure. The horizontal end of the support 6 is fixedly connected to the top of the base 1 through the locking rod 7, so as to ensure the ease of disassembly and assembly of the support 6. The connecting component includes a connecting sleeve 8 that is rotatably engaged with the outer wall of the support 6 through the bearing 14. The connecting sleeve 8 is sleeved on the outside of the boss 15. A fastening rod 9 is screwed onto the top of the connecting sleeve 8. The open end of the fastening rod 9 abuts against the outer wall of the boss 15. After the connecting sleeve 8 is sleeved onto the outer wall of the boss 15, the support 6 is fixed to the base 1. The fastening rod 9 completes the fixation of the connecting sleeve 8 and the boss 15.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a rubber pad is fixedly connected to the inner wall of the connecting sleeve 8, and the rubber pad abuts against the outer wall of the rotating rod 16. After the connecting sleeve 8 is fitted onto the outer wall of the protrusion 15 and fixed by the fastening rod 9, the rubber pad on the inner wall of the connecting sleeve 8 will be in contact with the outer wall of the open end of the rotating rod 16. The friction between the rubber pad and the rotating rod 16 can limit the axial deflection of the rotating rod 16 during the rotation of the rotating cylinder 4, thereby ensuring the stability of the fabric winding and unwinding device for garment processing.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the pushing assembly includes two sets of movable seats 17. The outer wall of the rotating rod 16 is screwed to the inner wall of the two sets of movable seats 17 through two sets of opposite threaded grooves. Push rods 18 are hinged to the outer wall of the two sets of rotating rods 16. The open ends of the two sets of push rods 18 are hinged to the outer wall of the inner expansion seat 5. The rotation of the rotating rod 16 drives the two sets of movable seats 17 to move relative to each other. The two sets of push rods 18 change their posture to push the inner expansion seat 5 to move telescopically. The guiding assembly includes a fixedly connected roller 10 and a vertical rod 11. A bottom sleeve 12 is fixedly connected to the top of the base 1. A spring 13 is fixedly connected between the bottom of the vertical rod 11 and the inner wall of the bottom sleeve 12 to ensure the tension of the fabric during the transfer process.

[0029] Working principle: The fabric roll is placed outside the rotating drum 4. The rotating rod 16 is rotated, which pushes the component to expand multiple sets of inner expansion seats 5 outward until the outer walls of the multiple sets of inner expansion seats 5 are tightly fitted with the inner wall of the roll, thus fixing the rotating drum 4 and the roll. Then, the movable support 6 is moved so that the connecting sleeve 8 is fitted onto the outer wall of the protrusion 15. The support 6 is then fixed to the base 1. The fastening rod 9 is used to fix the connecting sleeve 8 and the protrusion 15. The driving component 3 drives the roll to rotate through the rotating drum 4. The connecting sleeve 8 rotates with the support 6 through the bearing 14, thus achieving stable fabric winding. After the connecting sleeve 8 is fitted onto the outer wall of the protrusion 15 and fixed by the fastening rod 9, the rubber pad on the inner wall of the connecting sleeve 8 will be in contact with the outer wall of the open end of the rotating rod 16. The friction between the rubber pad and the rotating rod 16 can limit the axial deflection of the rotating rod 16 during the rotation of the rotating drum 4, thus ensuring the stability of the fabric winding device for garment processing.
