Description

Technical Field

[0001] This utility model relates to the field of woven bag production, and in particular to a positioning device for woven bag production. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally polypropylene, polyethylene, polyester, nylon, etc. The weave density refers to the number of warp and weft yarns within a 100mm x 100mm woven fabric. Woven bags are lightweight, sturdy, durable, inexpensive, and easy to recycle, making them widely used in agriculture, industry, and commerce. In agriculture, woven bags are commonly used to package fertilizers, seeds, and feed; in industry, they are used to package cement, chemical raw materials, and ores; and in commerce, woven bags are also used as commodity packaging bags and logistics packaging bags.

[0003] The production of woven bags requires multiple processes such as edge binding and film coating. However, the existing processing methods mostly involve manual handling of the woven bags, with film coating or edge binding done at the other end of the bag. There is no equipment specifically designed for positioning the woven bags, which to some extent affects the production efficiency and product quality of woven bags. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for woven bag production, which solves the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a positioning device for woven bag production, which includes: a base, a worktable set on the base, a turntable set on the worktable, and a positioning post set on the turntable. The woven bag to be processed is placed on the positioning post for positioning, and the rotation of the turntable facilitates the processing of the opening of the woven bag.

[0006] A further technical solution of this utility model is: the workbench is equipped with a rotary motor connected to the turntable, and the turntable is driven to rotate by the rotary motor.

[0007] A further technical solution of this utility model is: the turntable is provided with a sliding groove, which is used to install the side support mechanism.

[0008] A further technical solution of this utility model is that the top of the positioning post is flat, which matches the shape of the bottom of the woven bag.

[0009] A further technical solution of this utility model is: the positioning column is provided with a side support mechanism, which is used to open the opening of the woven bag to facilitate subsequent processing.

[0010] A further technical solution of this utility model is: the side support mechanism includes: a propulsion cylinder, a support rod, and a support plate. The support rod is connected to the slide groove via a slider. The support plate is connected to the outer end of the support rod. The propulsion cylinder is connected to the turntable. The support rod and the support plate are connected to the turntable via a slider. The support rod and the support plate move along the slide groove direction. Four sets of support rods and support plates are arranged. The outer edge of the support plate is arc-shaped.

[0011] A further technical solution of this utility model is: the inner end of the support rod is provided with an inclined surface, and the bottom end of the push rod of the propulsion cylinder is placed directly above the inner end of the support rod. The support rod is pushed by the push rod at the bottom end of the propulsion cylinder, so that the support rod moves outward in the slide groove.

[0012] A further technical solution of this utility model is: the bottom end of the push rod of the propulsion cylinder is provided with a conical surface that matches the inclined surface, and the conical push rods of the four inclined surfaces match the inclined surfaces of the four sets of support rods, so that the four support rods can be pushed to move simultaneously.

[0013] A further technical solution of this utility model is: a return spring for connecting the slider is provided in the groove, and the support rod automatically returns to its original position when the push rod is retracted.

[0014] The beneficial effects of this utility model are as follows: The positioning device for woven bag production of this utility model has a simple structure. The positioning column positions the woven bag, and the bottom turntable drives the rotation of the positioning column to facilitate subsequent processing. The side support mechanism makes it easy for the device to open the opening of the woven bag, which facilitates subsequent processing such as edge wrapping and film coating, and greatly improves the production efficiency of woven bags.
