Abstract
Description
Technical Field
[0001] This utility model relates to the field of document bag manufacturing, and in particular to a document bag indentation device. Background Technology
[0002] After the document bag is produced, it needs to be creased in a designated area to facilitate folding later. However, the existing creasing is done manually, which is inefficient.
[0003] Therefore, it is necessary to design an automatic creasing device for document bags. Utility Model Content
[0004] The technical problem this invention aims to solve is that after the document bag is produced, a designated area of the document bag needs to be creased to facilitate subsequent folding. However, existing creasing is done manually, which is inefficient.
[0005] To solve the above-mentioned technical problems, the present invention provides a document bag creasing device, which includes a creasing platform and a fixing component. A support rod is installed on one side of the creasing platform, and a slider is slidably connected to the top of the support rod. A servo motor is installed on the side wall of the support rod, and a threaded post is fixedly installed on the output shaft of the servo motor. The threaded post passes through the slider and is threadedly connected to it. A cylinder telescopic rod is installed at the bottom of the slider, and a pressure block is fixedly installed at the other end of the cylinder telescopic rod.
[0006] The fixing component includes a fixing frame, with latches on both sides of the bottom of the fixing frame. A threaded rod is threadedly connected to the latches, a knob is fixedly installed at the lower end of the threaded rod, and a washer is rotatably installed at the upper end of the threaded rod.
[0007] A rod is inserted into the top of the fixed frame, a pull block is fixedly installed at the top of the rod, a spring is fixedly connected to the bottom of the pull block, the other end of the spring is fixedly connected to the top of the fixed frame, and a clamping strip is fixedly installed at the bottom of the rod.
[0008] The surface of the indentation table has several slots, and an indentation post with a raised top is inserted into the inside of the slot. A pull ring is fixedly installed at the outer end of the indentation post.
[0009] The support rod and the indentation table are installed by sliding.
[0010] The beneficial effects of this utility model are as follows:
[0011] The system consists of threaded posts, a fixed frame, and indentation posts. A fixing assembly secures the document bag to be indented. A cylinder then extends and retracts, pressing a pressure block onto the bag. A servo motor rotates the threaded posts, causing the slider to slide automatically and indent the bag. The fixed frame is inserted into the indentation platform from one side. After adjusting its position, a knob is rotated, causing the threaded rod to rotate and pushing the shim upwards, thus securing the frame to the platform and facilitating bag fixation. Once fixed, the bag is placed under the clamping strip. A spring continuously pulls down the pull block, causing the insert rod to clamp the bag. After indentation, pulling up the pull block releases the clamping strip. Since different document bags have different indentation positions and widths, various indentation posts are available to accommodate different indentation locations. Multiple slots accommodate different indentation positions, and a pull ring facilitates easy replacement of the indentation posts. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0018] Please see Figure 1-4The creasing device includes a creasing table 1 and a fixing assembly. A support rod 2 is installed on one side of the creasing table 1, and a slider 3 is slidably connected to the top of the support rod 2. A servo motor 4 is installed on the side wall of the support rod 2, and a threaded post 5 is fixedly installed on the output shaft of the servo motor 4. The threaded post 5 passes through the slider 3 and is threadedly connected to it. A cylinder telescopic rod 6 is installed at the bottom of the slider 3, and a pressure block 7 is fixedly installed at the other end of the cylinder telescopic rod 6. The fixing assembly is used to fix the document bag that needs to be creasing. Then, the cylinder telescopic rod 6 is controlled to drive the pressure block 7 to press on the document bag. Then, the servo motor 4 is started, and the servo motor 4 drives the threaded post 5 to rotate. The slider 3 will then slide automatically, driving the pressure block 7 to creasing the document bag.
[0019] The fixing component includes a fixing frame 8, with lugs 9 on both sides of the bottom of the fixing frame 8. A threaded rod 10 is threadedly connected to the lugs 9. A knob 11 is fixedly installed at the lower end of the threaded rod 10, and a washer 12 is rotatably installed at the upper end of the threaded rod 10. The fixing frame 8 is inserted into the indentation table 1 from one side. After adjusting the position of the fixing frame 8, the knob 11 is rotated, which drives the threaded rod 10 to rotate and pushes the washer 12 upward, thus fixing the fixing frame 8 onto the indentation table 1, which facilitates the fixing of the document bag.
[0020] A rod 16 is inserted into the top of the fixed frame 8. A pull block 13 is fixedly installed at the top of the rod 16. A spring 14 is fixedly connected to the bottom of the pull block 13. The other end of the spring 14 is fixedly connected to the top of the fixed frame 8. A clamping strip 15 is fixedly installed at the bottom of the rod 16. After the fixed frame 8 is fixed, the document bag is placed under the clamping strip 15. The spring 14 always pulls the pull block 13 down, so that the rod 16 drives the clamping strip 15 to clamp the document bag. After the indentation is finished, the pull block 13 is pulled up, and the rod 16 drives the clamping strip 15 upward, so that the clamping strip 15 can be released.
[0021] The surface of the embossing table 1 is provided with several slots 17, and embossing posts 18 with raised tops are inserted into the slots 17. Pull rings 19 are fixedly installed on the outer ends of the embossing posts 18. Since different document bags have different embossing positions and embossing widths, the embossing posts 18 are designed in various ways to press various embossing marks. Multiple slots 17 are convenient to adapt to different embossing positions, and the pull rings 19 are convenient to pull the embossing posts 18 for easy replacement.
[0022] The support rod 2 and the indentation table 1 are installed in a sliding manner, which is convenient for indentation operations in multiple positions.
[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
