Technical Field

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

[0002] Plastic woven bags are plastic packaging products made from polypropylene or polyethylene resin as the main raw material, which is extruded and stretched into flat filaments, and then woven and made into bags. They are widely used as packaging materials for fertilizers, chemical products and other items. During the production process of plastic woven bags, the two sides need to be folded.

[0003] Existing folding devices, after folding, cause the plastic woven bag to unfold due to elastic restoring, as the folded area is formed by plastic deformation. This affects the folding effect, resulting in the woven bag becoming deformed and loose, thus increasing the defect rate.

The compaction mechanism 2 includes a fixed base plate 201, a limiting slider 202, a compaction scraper 207 for compacting the folded edge of the plastic woven bag, and an adjusting push plate 208 for adjusting the compaction force of the compaction scraper 207.

[0026] Specifically, a limiting slider 202 is provided at the bottom of the fixed base plate 201, and the top of the limiting slider 202 is provided on the elastic connecting plate 203. A guide arc plate 204 is provided at one end of the elastic connecting plate 203, and the two plates have a mirror symmetrical structure. A groove 205 is provided inside the guide arc plate 204, and an elastic arc plate 206 is provided inside the groove 205. A compaction scraper 207 is provided at one end of the elastic arc plate 206. A fixed frame 211 is provided outside the guide arc plate 204, and an adjusting push plate 208 is provided on the outer wall of the compaction scraper 207. The adjusting push plate 208 is slidably sleeved inside the fixed frame 211, and a pressing arc plate 213 is provided at one end of the adjusting push plate 208.

[0027] Specifically, the fixed frame 211 has a limiting block 212 inside, the adjusting push plate 208 has a limiting slot 210 that matches the shape of the limiting block 212 inside, the limiting block 212 is fixedly sleeved inside the limiting slot 210, the adjusting push plate 208 has an elastic support plate 209 on its outer wall, and the adjusting push plate 208 is located at both ends of the elastic support plate 209.

[0028] Specifically, the folded edge plate 102 has a limiting groove 105 that matches the shape of the limiting slider 202. The limiting slider 202 is slidably sleeved inside the limiting groove 105. The folded edge plate 102 has a placement groove 104 inside. The fixed base plate 201 has a fixing bolt 214 inside. The fixed base plate 201 is installed inside the placement groove 104 by the fixing bolt 214.

[0029] Example 1:

[0030] In this embodiment, to address the problem of the folded edge of the plastic woven bag unfolding due to elastic reset, resulting in deformation and looseness of the woven bag and an increased defect rate, the technical solution of this embodiment is as follows (refer to...). Figures 1 to 6The elastic connecting plate 203 is U-shaped, and the guide arc plate 204 is an arc-shaped plate. The elastic connecting plate 203 and the guide arc plate 204 are an integral structure. Both the elastic connecting plate 203 and the guide arc plate 204 are mirror-symmetrical on both sides of the fixed base plate 201. The elastic arc plate 206 is an arc-shaped elastic curved surface structure. The elastic arc plate 206 is set at both ends of the compaction scraper 207 and is mirror-symmetrical. The compaction scraper 207 is C-shaped. When the folding plate 102 folds the plastic woven bag, the plastic woven bag is driven by the conveyor belt 103 to fold the edge. Laterally, guided by the guide arc plate 204, the folded edge of the plastic woven bag moves from the arc front end of the folding plate 102 to between the folding plates 102, and the folding plate 102 is used to fold the edge of the plastic woven bag. At the same time, driven by the conveyor belt 103, the folded plastic woven bag is moved between the two compacting scrapers 207. Then, under the action of the elastic arc plate 206, the compacting scraper 207 comes into contact with the folded edge of the plastic woven bag. During the movement of the plastic woven bag, the compacting scraper 207 is used to compact the folded edge of the plastic woven bag.

[0031] Example 2:

[0032] In this embodiment, to address the problem of insufficient compressive strength of the plastic woven bag affecting the folding effect, the technical solution is as follows (refer to...). Figures 4 to 6 The adjusting push plate 208 is J-shaped, and the elastic support plate 209 is an arc-shaped elastic curved surface structure. The adjusting push plate 208 is set at both ends of the elastic support plate 209. The adjusting push plate 208 has a mirror symmetrical structure at both ends of the elastic support plate 209. The shape of the limiting slot 210 is adapted to the shape of the limiting block 212. By adjusting the position of the adjusting push plate 208 in the fixed frame 211, the compaction scraper 207 is squeezed and moved, thereby adjusting the distance between the compaction scrapers 207 to adjust the pressure of the compaction scrapers 207 on the folded edge of the plastic woven bag to meet different compaction requirements and improve its practicality.

[0033] Based on the above embodiments, it can be concluded that: during the processing of plastic woven bags, the compaction mechanism 2 is installed on the outside of the folding plate 102 by fixing bolts 214. Then, under the action of the guide arc plate 204, the folded edge of the plastic woven bag is moved between the two compaction scrapers 207. Then, under the action of the elastic arc plate 206, the compaction scrapers 207 come into contact with the folded edge of the plastic woven bag. During the movement of the plastic woven bag, the compaction scrapers 207 are used to compact the folded edge of the plastic woven bag, so as to avoid the folded edge of the plastic woven bag from being affected by the elastic reset and unfolding, thus preventing the woven bag from deforming and becoming loose, and reducing the defect rate.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
