[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, woven bag hemming is a process performed on the side edges of woven bags during the production process, which can ensure that the edge portions of the woven bags are closed and smooth. Most existing woven bag hemming devices process the edges of the woven bags by mechanical hard pressing during the hemming process, and the mechanical hard pressing will cause pressure damage to the edges of the woven bags, and the hemming marks will be more obvious. In order to solve such problems, a plastic woven bag hemming device is proposed, comprising a processing base plate 1, on which a folding piece 2 is provided, and the folding piece 2 comprises two folding pressing plates 21 which are spaced apart and arranged on the processing base plate 1, and a slide groove 211 for the woven bags to pass through in an orderly manner is formed between the two folding pressing plates 21, and the two folding pressing plates 21 are arranged along the woven bags passing through the groove. It is gradually bent inward to form a curved surface for folding the side edges of the woven bag. The two folding pressure plates 21 are located at one end of the slide groove 211 and are provided with a flattening piece 3 for flattening the folded edges of the woven bag. One side of the flattening piece 3 is also provided with a detection piece 4 for detecting the thickness of the woven bag. By setting the processing base plate 1, the woven bag hemming process can be carried out in a stable environment, and the curved slide groove 211 formed by the two folding pressure plates 21 in the folding piece 2 can achieve the purpose of gradually folding the edge of the woven bag along the curved surface, avoiding the process of mechanical hard pressing, and at the same time, the sliding folding is carried out to ensure the purpose of stable and orderly progress of the entire folding process, and the subsequent setting of the detection piece 4 and the flattening piece 3 can ensure the purpose of ensuring the accuracy of the entire folding.

[0027] It should be noted that the specific arrangement of the curved surface of the above-mentioned folding plate 21 is as follows Figure 3As shown, the folding plate 21 is in the sliding direction of the woven bag to form an initial end and an end, and the initial end of the folding plate 21 is vertically arranged, and the end of the folding plate 21 is horizontally arranged, and the curved surface formed between the initial end and the end tends to extend gradually; the distinguishing point between the initial end and the end is determined by the sliding direction of the woven bag. When the woven bag just enters the two folding plates 21, it is the initial end. After the folding process is completed, the position where the woven bag falls off the slide 211 is the end. The purpose of setting the entire curved surface is to enable the edge of the woven bag to be folded along the curved surface, thereby ensuring the purpose of natural folding.

[0028] Furthermore, the specific structure of the flattening piece 3 is as follows: the flattening piece 3 includes a heating element 32 arranged in the processing base plate 1, and a flattening base plate 31 that slides vertically up and down is spaced apart on the upper side of the heating element 32, and a telescopic cylinder 311 is provided on the upper side of the flattening base plate 31 for driving the flattening base plate 31 to slide vertically up and down; the operation of the telescopic cylinder 311 can achieve the purpose of making the flattening base plate 31 slide downward and gradually approach the heating element 32. At this time, the folded edge of the woven bag on the upper side of the heating element 32 will be changed in softness by heating, thereby ensuring that the subsequent flattening base plate 31 can better flatten the edge of the woven bag.

[0029] In addition, the process of the woven bag sliding in the slide groove 211 can be pushed in an orderly manner by an external power or manually, and it is only necessary to ensure that the woven bag slides in an orderly manner along the upper side of the processing bottom plate 1.

[0030] It should also be noted that a first support plate 12 is provided on one side of the processing base plate 1, a horizontally distributed second support plate 121 is provided on the upper side of the first support plate 12, and the telescopic cylinder 311 is installed on the bottom of the second support plate 121; the purpose of stably installing the telescopic cylinder 311 can be achieved by setting the first support plate 12 and the second support plate 121.

[0031] In addition, the specific structure of the above-mentioned detection member 4 is as follows: the detection member 4 includes a detection slide 41 which slides vertically up and down and is arranged on the upper side of the processing base plate 1; a detection space 411 for detecting the thickness of the woven bag is formed between the detection slide 41 and the processing base plate 1; an adjustment member for adjusting the spacing size of the detection space 411 is provided on the upper side of the detection slide 41; after the edge of the woven bag is flattened in an orderly manner, it is necessary to slide through the detection space 411, and the height spacing of the detection space 411 is to detect whether the thickness of the woven bag after folding meets the standard requirements.

[0032] It is worth mentioning that the above-mentioned adjusting member is provided to adjust the height spacing size of the detection space 411. By adjusting the adjusting member, the purpose of orderly detection of different height requirements can be achieved. Specifically, the structure of the adjusting member is as follows: the adjusting member includes an adjusting screw 43 rotatably arranged on the top of the detection slide 41, and the adjusting screw 43 extends upward through the second support plate 121, and the adjusting screw 43 is threadedly connected to the support plate; the purpose of adjusting the setting height of the detection slide 41 can be achieved by rotating the adjusting screw 43, thereby achieving the purpose of adjusting the height size of the detection space 411. Furthermore, in order to ensure the stability of the above-mentioned detection slide 41 during the up and down sliding process, in this embodiment, guide slide rods 42 are also provided on both sides of the detection slide 41 for ensuring the vertical sliding stability of the detection slide 41, and the guide slide rods 42 extend upward through the second support plate 121; the setting of the two guide slide rods 42 can ensure that the detection slide 41 is more stable and orderly during the up and down sliding process.

[0033] Additionally, in order to ensure that the processing base plate 1 is stably set, in this embodiment, a plurality of mounting frames 11 for supporting the processing base plate 1 are provided at the bottom of the processing base plate 1; the installation of the mounting frames 11 can ensure that the processing base plate 1 is stably set on the ground.

[0034] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
