Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production, in particular to an improved easy-standing woven bag. Background Art

[0002] An "Easy Lift Woven Bag" is a special type of woven bag used for packaging and transporting items. This type of bag is usually made of polypropylene (PP) or other synthetic fibers, usually designed in a square or rectangular shape, and has a special structure at the bottom that allows it to stand on its own when not filled with items. This design makes loading and stacking more convenient, improving the stability and stackability of the bag.

[0003] During the production process of woven bags, the woven fabric made of plastic strips needs to be wound and collected on a winding roller for subsequent movement to a cutting and sewing machine to make woven bags. The existing devices have trouble fixing the winding roller for the wound woven fabric, and after winding, the operator needs to manually use tools such as a cutter to cut the woven fabric. Manual cutting with uneven force is likely to cause uneven cutting edges, affecting the subsequent use of the woven fabric, and there are certain operational risks when manually using tools such as a cutter.

Detailed Embodiment

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0015] Refer to Figures 1 - 3As shown in the figure, an improved easy-to-erect woven bag includes a base 1. A rectangular block 2 is fixedly connected to the upper end of the base 1. An electric telescopic rod 3 with a telescopic end facing the direction of the rectangular block 2 is fixedly installed at the left end of the rectangular block 2. The telescopic end of the electric telescopic rod 3 penetrates through the rectangular block 2 and is slidably connected thereto. The telescopic end of the electric telescopic rod 3 is fixedly connected to a trapezoidal block 4. The telescopic end of the electric telescopic rod 3 can be extended and retracted to drive the trapezoidal block 4 to move left and right. There are two lifting mechanisms symmetrically arranged front and back at the upper end of the base 1. The lifting mechanism includes a U-shaped block 5. The U-shaped block 5 is fixedly connected to the base 1. A sliding rod 6 is fixedly connected between the upper and lower inner walls of the U-shaped block 5. A moving block 7 is slidably sleeved on the sliding rod 6. A connecting rod 8 is arranged between the two lifting mechanisms. The two ends of the connecting rod 8 are respectively fixedly connected to the two moving blocks 7. A first stop block 11 and a second stop block 12 are respectively arranged on the inclined surface of the trapezoidal block 4. Both the first stop block 11 and the second stop block 12 are fixedly connected to the inclined surface of the trapezoidal block 4. The connecting rod 8 is located between the first stop block 11 and the second stop block 12 and is in sliding contact with the inclined surface of the trapezoidal block 4. When the telescopic end of the electric telescopic rod 3 extends forward, the trapezoidal block 4 moves to the right. The connecting rod 8 is in sliding contact with the inclined surface of the trapezoidal block 4. The trapezoidal block 4 squeezes it upward through the inclined surface, so that the connecting rod 8 rises. The two moving blocks 7 slide upward along the sliding rod 6 until the connecting rod 8 is blocked by the first stop block 11, and the telescopic end of the electric telescopic rod 3 stops extending forward. The principle of the connecting rod 8 descending is the same. By contracting the telescopic end of the electric telescopic rod 3, the trapezoidal block 4 is driven to move left. Under the influence of gravity, the two moving blocks 7 slide downward along the corresponding sliding rods 6 to drive the connecting rod 8 to descend until it is blocked by the second stop block 12, and the electric telescopic rod 3 stops contracting. The first stop block 11 and the second stop block 12 prevent the connecting rod 8 from detaching from the inclined surface of the trapezoidal block 4.

[0016] Two horizontally arranged limiting plates 13 corresponding to each other front and back are fixedly connected to the upper end of the base 1. An extension plate 14 is fixedly connected to the right end of the base 1. A fixed shaft 16 is rotatably connected to the front end of the extension plate 14. The front end of the fixed shaft 16 has a thread. A motor 15 for driving the fixed shaft 16 to rotate is fixedly installed at the rear end of the extension plate 14. A retaining disk 17 is fixedly sleeved on the fixed shaft 16. Several fixed insertion blocks 18 are arranged at the front end of the retaining disk 17. A winding roller 19 is slidably sleeved on the fixed shaft 16. Several retaining holes 20 corresponding to the fixed insertion blocks 18 are opened on the front and rear end baffles of the winding roller 19. A fixing ring 21 is threadedly sleeved on the front end of the fixed shaft 16. When the winding roller 19 is sleeved on the fixed shaft 16, the fixed insertion blocks 18 at the front end of the retaining disk 17 are inserted into the retaining holes 20 on the front and rear end baffles of the winding roller 19. By rotating the fixing ring 21, the fixing ring 21 moves along the thread at the front end of the fixed shaft 16 towards the retaining disk 17, so as to clamp the winding roller 19 between the retaining disk 17 and the fixing ring 21, and fix the winding roller 19 on the fixed shaft 16. The woven fabric is as Figure 1, it is fixed on the winding roller 19 between the two limit plates 13 and is in sliding contact with the base 1. The motor 15 drives the fixed shaft 16 to rotate clockwise, thereby driving the winding roller 19 to rotate to gather and wind the woven cloth. A pressure block 9 is fixedly sleeved on the connecting rod 8, and a guillotine 10 is installed at the lower end of the pressure block 9. The electric telescopic rod 3 is set to high power and has a fast contraction speed. After the woven cloth on the winding roller 19 is fully wound, the motor 15 stops rotating, and the electric telescopic rod 3 is contracted. The pressure block 9 drops due to gravity. The guillotine 10 at the lower end of the pressure block 9 drops vertically under the influence of gravity and finally collides with the base 1, cutting the woven cloth evenly. Then the operator can rotate the fixed ring 21 to remove it, and then remove the fully wound winding roller 19 and install the empty winding roller 19. The guillotine 10 squeezes the connecting rod 8 through the trapezoidal block 4 to rise, fixes the woven cloth on the new winding roller 19 and continues the winding operation.

[0017] When using, woven cloth Figure 1 The cloth is wound around the winding roller 19 after passing between the two limit plates 13 above the base 1. The motor 15 drives the fixed shaft 16 to rotate clockwise, and the winding roller 19 rotates to gather and wind the woven cloth. After the cloth is fully wound, the motor 15 stops running, and the guillotine 10 drops vertically by gravity and collides with the base 1 to cut the woven cloth. Then the guillotine 10 rises, and the operator rotates the fixing ring 21 to remove it, then removes the fully wound winding roller 19 and installs the empty winding roller 19, fixes the woven cloth on the new winding roller 19 and continues the winding operation.
