Description

Technical Field

[0001] This utility model relates to the technical field of woven bag production equipment, and in particular to an automatic feeding device for a woven bag making machine. Background Technology

[0002] In the production process of woven bag making machines, the feeding of raw materials is a key link between "raw material unwinding" and "bag making". Traditional bag making machines mostly rely on manual feeding. The speed of manual feeding is difficult to match with the processing speed of bag making machines, which easily leads to the lag or accumulation of raw materials, resulting in interruption of the bag making rhythm. When manually adjusting the alignment of raw materials, the error is large, which affects the quality of finished products. As the demand for woven bags develops towards large-scale and standardized production, bag making machines are gradually upgrading to high speed and automation. Traditional manual feeding can no longer meet the needs of efficient production. Under this background, automatic feeding devices for woven bag making machines have emerged.

[0003] The device uses a structure driven by a motor and rollers to precisely control the raw material feeding rate according to the processing speed of the bag making machine. This avoids speed deviations caused by manual feeding, ensures that the raw materials are continuously and stably delivered to the processing station, and ensures that processes such as cutting and heat sealing are carried out in a continuous manner. It also reduces equipment idling caused by feeding interruptions, thereby improving the qualification rate of woven bags.

[0004] In existing technologies, some devices require operators to repeatedly disassemble and install them using tools such as wrenches and screwdrivers. Especially for heavy, thick woven fabric rollers, multiple people are needed to move and align them, significantly increasing the time required for each replacement. In large-scale production, frequent replacement of raw material rollers can lead to long downtime of the equipment, disrupting the continuous processing rhythm of the bag making machine, greatly reducing the output of finished products per unit time, and dragging down the overall production progress. Therefore, an automatic feeding device for woven bag making machines is proposed to solve the above problems. Utility Model Content

[0038] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] An automatic feeding device for a woven bag making machine, as described in the following description. Figures 1 to 3 The system includes a mounting frame 1, which provides a fixed foundation for the mounting groove 2 and mounting plate 3 to ensure overall structural stability. The mounting frame 1 has an internal mounting groove 2, which provides installation and rotation space for the rotating roller 5 and the raw material roller 6. The mounting plate 3 is fixedly connected to the outside of the mounting frame 1, supporting a support frame 4 and providing mounting points for related components. The support frame 4 is fixedly connected to the bottom of the mounting plate 3, assisting in supporting the mounting frame 1 and improving overall stability. The rotating roller 5 is rotatably connected inside the mounting groove 2, assisting the raw material roller 6 in rotating to achieve raw material conveying. The raw material roller 6 is detachably connected to the outside of the rotating roller 5, winding woven fabric and other raw materials to provide a base material for bag making. A disassembly mechanism 7 is installed inside the raw material roller 6, enabling quick disassembly and replacement. A tension adjustment mechanism 8 is installed inside the mounting frame 1, dynamically balancing the raw material tension to ensure stable conveying. An adjustment roller 9 is slidably connected inside the mounting frame 1, moving in conjunction with the tension adjustment mechanism 8 to adjust the tension.

[0041] The disassembly mechanism 7 includes a motor 71, which provides power to rotate the support column 72 and assists the raw material roller 6 in operation. The drive end of the motor 71 is fixedly connected to the support column 72. The support column 72 supports the sliding frame 73 and the drive assembly 74 and transmits power to the motor 71. The sliding frame 73 is rotatably connected to the outside of the support column 72. The sliding frame 73 provides sliding support and trajectory limitation for the sliding block 755. The drive assembly 74 is provided on the outside of the support column 72. The drive assembly 74 provides power to the action of the external support fixing assembly 75 to realize the fixing and unlocking of the raw material roller 6. The external support fixing assembly 75 is provided on the outside of the sliding frame 73. The external support fixing assembly 75 realizes the fixing and disassembly of the raw material roller 6 by tightening or loosening.

[0042] The drive assembly 74 includes a second motor 741, which provides the core power to drive the rotating block 742 to rotate. The drive end of the second motor 741 is fixedly connected to the rotating block 742. The second motor 741 drives the rotating block 742 to rotate, thereby transmitting power to the connecting ring 744. The rotating block 742 is slidably connected to the outside of the connecting ring 744. The rotating block 742 drives the connecting ring 744 to rotate, causing the threaded column 743 to move. The support column 72 is slidably connected to the outside of the rotating column 745. The rotating column 745 moves in conjunction with the threaded column 743 to drive the external support fixing assembly 75 to move. The rotating column 745 is provided with a threaded column 743 inside. When the threaded column 743 rotates, it pushes the external support fixing assembly 75 to tighten or loosen. The external support fixing assembly 75 includes multiple support plates 751. The support plates 751 directly contact the inner wall of the raw material roller 6 to achieve tightening and fixing.

[0043] Rotating plates 752 are rotatably connected to the outside of the support plate 751. The rotation of the rotating plates 752 converts the movement of the fixed plate 754 into the opening and closing of the support plate 751. The other end of each of the multiple rotating plates 752 is rotatably connected to a connecting plate 753. The connecting plate 753 connects the rotating plates 752 and the fixed plate 754 to transmit power. The outside of the connecting plates 753 is fixedly connected to a fixed plate 754. The fixed plate 754 drives the connecting plate 753 and the rotating plates 752 to move synchronously. The outside of the fixed plate 754 is fixedly connected to a sliding block 755. The sliding block 755 slides in the sliding frame 73 to drive the fixed plate 754 to move. The outside of the raw material roller 6 is rotatably connected to the inside of the mounting groove 2, so that the raw material roller 6 can rotate stably in the mounting groove 2 to transport raw materials.

[0044] The motor 71 is externally fixedly connected to the inside of the rotating roller 5, ensuring that the motor 71 is fixed in position to provide power to the support column 72. The sliding frame 73 is externally rotatably connected to the inside of the raw material roller 6, so that the sliding frame 73 rotates synchronously with the raw material roller 6. The external support fixing component 75 is externally rotatably connected to the inside of the raw material roller 6, ensuring that the external support fixing component 75 can stably support the inner wall of the raw material roller 6. The external sliding block 755 is slidably connected to the inside of the sliding frame 73, limiting the movement trajectory of the sliding block 755 to ensure its stable movement. The external connecting ring 744 is externally rotatably connected to the outside of the threaded column 743, so that the connecting ring 744 drives the threaded column 743 to rotate, thereby triggering the action of the external support fixing component 75. Thus, the old raw material roller 6 can be quickly disassembled and the new raw material roller 6 can be installed.

[0045] Specifically, when disassembling the raw material roller 6, motor 2 741 starts and drives rotating block 742 and connecting ring 744 to rotate. Connecting ring 744 drives threaded column 743 to rotate, causing rotating column 745 to move. Rotating column 745 pushes sliding block 1 755 to slide within sliding frame 73. Sliding block 1 755 drives fixed plate 754 and connecting plate 1 753 to move. Connecting plate 1 753 causes rotating plate 1 752 to rotate. Support plate 751 retracts and detaches from the inner wall of raw material roller 6, allowing raw material roller 6 to be removed. During installation, the operation is reversed so that support plate 751 tightens raw material roller 6, completing quick disassembly and assembly and improving production efficiency.

[0046] Reference Figure 4 and Figure 5 The tension adjustment mechanism 8 includes a motor 3 81, which provides power to rotate the rotating plate 2 82. The drive end of the motor 3 81 is fixedly connected to the rotating plate 2 82. The motor 3 81 drives the rotating plate 2 82 to rotate, thereby transmitting power to the connecting plate 2 84. A mounting block 83 is rotatably connected to the outside of the rotating plate 2 82, providing rotational support to ensure its stability. The connecting plate 2 84 is rotatably connected to the outside of the rotating plate 2 82, and the rotating plate 2 82 drives the connecting plate 2 84. Rotation causes the support block 85 to move. The support block 85 is rotatably connected to the outside of the connecting plate 2 84. The support block 85 connects the connecting plate 2 84 and the sliding block 2 86 to transmit power. The sliding block 2 86 is fixedly connected to the other side of the support block 85. The support block 85 drives the sliding block 2 86 to slide on the mounting frame 1. The mounting frame 1 has a groove on its outside to provide sliding space and trajectory for the sliding block 2 86. The outside of the sliding block 2 86 is slidably connected to the outside of the mounting frame 1, so that the sliding block 2 86 drives the adjusting roller 9 to move to achieve tension adjustment.

[0047] Specifically, when adjusting the tension, motor 3 81 starts and drives rotating plate 2 82 to rotate. Rotating plate 2 82 drives connecting plate 2 84 to rotate. Connecting plate 2 84 pushes support block 85 and sliding block 2 86 to move up and down in the groove of mounting frame 1. Sliding block 2 86 drives adjusting roller 9 to move and change the tension of the raw material, so as to achieve precise tension adjustment and ensure stable delivery of raw materials.

[0048] The implementation principle of this application embodiment is as follows: When the raw material roller 6 is disassembled and replaced, the drive component 74 is activated. At this time, the second motor 741 starts. When the second motor 741 starts, the drive end starts to drive the rotating block 742 and the connecting ring 744 to rotate. At the same time, the outer support fixing component 75 is activated as a whole. The sliding block 755 moves inside the sliding frame 73. The movement of the sliding block 755 causes the fixing plate 754 to move synchronously. When the fixing plate 754 moves, it drives the rotating plate 752 to rotate. When the sliding block 755 slides to the other end inside the sliding frame 73, the raw material roller 6 is disassembled and replaced. This allows for the rapid disassembly of the old raw material roller 6 and the installation of the new raw material roller 6. The replacement of the raw material roller 6 can be completed in a short time, reducing equipment downtime and ensuring the continuous processing rhythm of the bag making machine. Especially in large-scale production, it can significantly increase the output of finished products per unit time and promote the overall production efficiency.

[0049] When adjusting the tension of the feed material, motor 3 81 is started first. When motor 3 81 starts, its drive end drives rotating plate 2 82 to rotate. When rotating plate 2 82 rotates, it drives connecting plate 2 84 to rotate synchronously. At this time, sliding block 2 86 moves up and down through the connection of support block 85. The internal connection of sliding block 2 86 drives the movement, thereby adjusting the tension of the feed material. This ensures that the material is always conveyed at a rate that matches the processing speed of the bag making machine, reducing equipment downtime caused by material accumulation or insufficient supply, ensuring the continuous operation of cutting, heat sealing, printing and other processes, and increasing the effective working time of the equipment. Especially in large-scale production, it can significantly reduce the production capacity loss caused by feed interruption.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
