[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The clamping device for woven bag production is a device used in the woven bag production process. Its main function is to compress the bag opening after the woven bag is sewn to make the bag opening smoother and more beautiful, while enhancing the firmness of the bag opening. When using the clamping device, the appropriate clamping force and time should be adjusted according to different woven bag specifications and materials to avoid damage to the woven bag or affecting production efficiency. At the same time, the device should be inspected and maintained regularly to ensure its normal operation and extend its service life.

[0003] The woven bag pressing devices currently on the market have the following problems when used:

[0004] 1. When using a traditional woven bag pressing device, a single pressing structure is usually used to press the woven bag, and the pressing area is usually fixed. Once a long woven bag is pressed, the pressing range will be insufficient, so the compatibility is poor when in use;

[0005] 2. Most woven bag compression devices often need to be continuously compressed during the application process. Once the woven bag is pulled during subsequent use, it is easy for the woven bag to be worn to varying degrees due to pulling and friction because it is in a squeezed state. Therefore, the protection of the woven bag is poor during application. Summary of the invention

[0006] The utility model aims to provide a pressing device for woven bag production to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: A clamping device for woven bag production, including a frame and a mounting plate, the side of the frame is fixedly connected to the mounting plate, and a mounting hole is opened on the top of the mounting plate. The inner side of the frame is fixedly connected to the first pressing plate, and an inner groove body is opened inside the first pressing plate. The number of the inner groove bodies is set in two groups, and the interior of the inner groove body is connected to the second pressing plate through a rotating shaft. A third pressing plate is provided on one side of the second pressing plate, and a limiting pull-out plate is embedded in the interior of the third pressing plate, and the other side of the limiting pull-out plate is fixedly connected to the second pressing plate.

Due to the installation of an extendable and stretchable structure, when a smaller volume of woven bags needs to be clamped, it only needs to be placed at the bottom. When the area of ​​the compressed woven bag is large, the second and third clamping plates can be rotated out from the bottom of the clamping plate, and a limit pull-out plate is installed inside the third clamping plate, so it can be extended and stretched to adapt to the use of woven bags with larger areas. Therefore, there will be no problem of insufficient clamping range during use, and its compatibility is strong;

[0015] 2. This clamping device for woven bag production has a first wear-resistant sheet embedded inside the first pressing plate, a second wear-resistant sheet embedded at the bottom of the second pressing plate, and a third wear-resistant sheet embedded at the bottom of the third pressing plate. Due to the installation of the wear-resistant sheet structure, it can avoid different degrees of wear caused by pulling and friction during use. Therefore, when using the clamping device, first install the first wear-resistant sheet, the second wear-resistant sheet, and the third wear-resistant sheet inside the first pressing plate, the second pressing plate, and the third pressing plate in sequence. After installation, even if the woven bag is in a squeezed state again, the woven bag is not prone to different degrees of wear caused by pulling and friction. Therefore, it has strong protection for the woven bag during use. BRIEF DESCRIPTION OF THE DRAWINGS
