Description

Technical Field

[0001] The utility model relates to the field of heat-sealing packaging machinery, in particular to a suction generating device applied to a heat-sealing film packaging device. Background Art

[0002] At present, in order to improve the efficiency of heat-sealing film packaging, it is usually realized by using a heat-sealing film packaging device. Most of the existing heat-sealing film packaging devices sequentially use a film feeding device, a folding device, a sealing edge device, a bagging device, a sealing device, and a cutting device to complete the packaging of related products with a roll of packaging film. The folding device folds the two ends of the horizontally entering packaging film upward in the length direction. The sealing edge device sequentially hot-presses the length direction of the folded packaging film to form a plurality of vertical sealing parts, so that a packaging space can be formed between adjacent vertical sealing parts, and the packaging space is used to hold related products. It can be seen that the packaging film entering the bagging device is in a folded state, and there are vertical sealing parts on the packaging film, so most of the inner walls of the packaging film are attached together, which will cause the packaging film to be unable to be directly used to hold the products to be packaged, and it is necessary to open the attached packaging film to realize bagging.

[0003] For this reason, a method of setting a pair of rolling suction bag turntable mechanisms on the bagging device to open the packaging film has now emerged. Among them, most of the existing pair of rolling suction bag turntable mechanisms are composed of a pair of rolling large suction bag turntables and small suction bag turntables. The large suction bag turntable and the small suction bag turntable are both horizontally arranged. A bag passing gap for the folded packaging film to pass through is reserved between the large suction bag turntable and the small suction bag turntable. A plurality of suction bag holes are respectively opened on the outer circumferential surfaces of the large suction bag turntable and the small suction bag turntable. Each suction bag hole is connected to the same suction fan through relevant pipelines, so that each suction bag hole can generate suction through the suction fan. In this way, when the packaging film passes through the bag passing gap, suction forces will act on both sides of it respectively, so as to achieve the purpose of opening the bag and receiving materials.

[0004] Since most of the components of the existing large suction bag turntable and small suction bag turntable are made of metal materials and processed by mechanical cutting, metal chips and metal powders cut during processing are likely to remain in each suction bag hole. And during use, the suction bag holes are also likely to inhale dust, mosquitoes, powder-like objects to be packaged or small particle-like objects to be packaged, etc. In this way, when the suction fan works, there will be a process of inhaling and discharging metal chips, metal powder dust, mosquitoes, powder-like objects to be packaged or small particle-like objects to be packaged.

[0005] Since the suction fan on the existing heat-sealing film packaging equipment exhausts directly, the metal debris, metal powder dust, mosquitoes, powdery items to be packaged or small particulate items to be packaged inhaled by the suction fan will be directly discharged onto or beside the heat-sealing film packaging equipment. Since the existing suction fans generally adopt a large suction force, the discharge speed of the suction fan will also be relatively large, thus easily causing the discharged substances to disperse everywhere. This not only pollutes the air in the packaging workshop, but also easily leads to the contamination of the items to be packaged, and will have an adverse impact on the health of the packaging workers. In particular, the metal powder discharged by the suction fan is extremely harmful.

[0006] Therefore, it is highly necessary to design a suction generating device applied to the heat-sealing film packaging equipment to solve the above technical problems. Utility Model Content

[0007] The purpose of the present utility model is to solve the above problems and deficiencies, and provide a suction generating device applied to the heat-sealing film packaging equipment. This suction generating device can filter out the inhaled metal debris, metal powder dust, mosquitoes, powdery items to be packaged or small particulate items to be packaged, etc., so as to avoid their direct discharge into the workshop. This can not only help improve the workshop environment, but also reduce the probability of the items to be packaged being contaminated, and can reduce the adverse impact on the health of the packaging workers.

[0018] Preferably, at least one U-shaped positioning strip is sleeved on the outer circumferential surface of the cylinder body, and fixing lugs are respectively formed by bending the two ends of the U-shaped positioning strip outwards.

[0025] As Figure 1As shown in the figure, a suction generating device applied to a heat-sealing film packaging device according to the present utility model includes a suction pipe 1, and a filtering component 2 is connected in series on the suction pipe 1.

[0026] In this suction generating device, by connecting the filtering component 2 in series on the suction pipe 1, the filtering component 2 can filter the air inhaled by the suction pipe 1 to filter out inhaled metal debris, metal powder dust, mosquitoes, powdery packaging materials to be packaged or small particulate packaging materials to be packaged, etc., so as to avoid their direct discharge into the workshop. This can not only help improve the workshop environment, but also reduce the probability of the packaging materials to be packaged being contaminated, and reduce the adverse effects on the bodies of packaging workers; especially, it can greatly reduce the harm caused by metal powder to packaging workers.

[0027] During actual use, the suction pipe 1 is connected and communicated with relevant suction bag holes on the heat-sealing film packaging device by using an existing structure, so that suction can be generated at the relevant suction bag holes, thus meeting the actual use requirements.

[0028] The suction pipe 1 is composed of an air pipe, which can meet the requirements of actual manufacturing and use.

[0029] As Figure 1 shown in the figure, a suction fan 3 is also connected in series on the suction pipe 1, and the filtering component 2 and the suction fan 3 are arranged in sequence along the direction from the suction end to the output end of the suction pipe 1. This can filter out metal debris, metal powder dust, mosquitoes, powdery packaging materials to be packaged or small particulate packaging materials to be packaged, etc. before they enter the suction fan 3, which can protect the blades of the suction fan 3. This can greatly reduce the probability of the blades of the suction fan 3 being damaged, thus helping to reduce the aging speed of the suction fan 3 and the damage speed of the suction fan 3, and further helping to extend the service life of the suction generating device.

[0030] As Figure 1 shown in the figure, the suction fan 3 is a vortex fan. By using a vortex fan, not only can more stable and reliable suction be generated, but also the noise can be relatively small, thus helping to further improve the reliability and applicability of this suction generating device.

[0031] As Figures 1 to 3 shown in the figure, the filtering component 2 includes a filtering cylinder body 21 and a filtering core 22. The filtering cylinder body 21 is connected in series on the suction pipe 1, and the filtering core 22 is installed in the filtering cylinder body 21. This can not only make the filtering component 2 have a simple structure, but also make the filtering component 2 have a very good filtering effect, which helps to further improve the applicability and reliability of this suction generating device.

[0032] The filtering core 22 is an existing filter cotton or filter net for filtering air, which can meet the filtering requirements.

[0033] As Figures 2 to 5 shown, the filter cylinder body 21 includes a cylinder cover 211 and a cylinder body 212 with one end closed. The inner hole of the cylinder body 212 forms a filter cavity 213. The filter core 22 is installed in the filter cavity 213, and the cylinder cover 211 is detachably installed on the opening of the cylinder body 212. This can meet the disassembly and assembly of the filter core 22, thus facilitating maintenance.

[0034] As Figure 1 shown in Figure 2 , the filter cylinder body 21 further includes at least two buckle locks 214. The cylinder cover 211 is installed on the opening of the cylinder body 212 through each buckle lock 214, and each buckle lock 214 is arranged around the axial center line of the cylinder body 212. This can conveniently and stably install the cylinder cover 211 on the cylinder body 212, which can not only improve the convenience of opening and closing the cylinder cover 211, but also improve the stability of installing the cylinder cover 211.

[0035] As Figure 3 shown, the cylinder cover 211 is sleeved on the opening end of the cylinder body 212. This can improve the stability and reliability of installing the cylinder cover 211, thus contributing to further improving the reliability of the suction generating device.

[0036] As Figures 1 to 3 , Figure 5 shown, a first docking convex pipe 215 communicating with the filter cavity 213 is arranged on the outer circumferential surface of the cylinder body 212, and a second docking convex pipe 216 communicating with the filter cavity 213 is arranged on the end face of the closed end of the cylinder body 212. The filter cavity 213 is connected in series to the suction pipeline 1 through the first docking convex pipe 215 and the second docking convex pipe 216. The setting of the first docking convex pipe 215 and the second docking convex pipe 216 can facilitate stable docking, thus being conducive to improving the convenience and stability of docking.

[0037] In the actual manufacturing process, two air pipes can be used to form the suction pipeline 1, and the end parts of the two air pipes are respectively sleeved on the first docking convex pipe 215 and the second docking convex pipe 216. The stainless steel hose clamps are also used to fix the two air pipes on the first docking convex pipe 215 and the second docking convex pipe 216, and the air pipe docked with the second docking convex pipe 216 is docked on the suction port of the suction fan 3. Furthermore, the air pipe docked with the first docking convex pipe 215 is connected and communicated with the suction bag hole on the heat sealing film packaging equipment. In this way, a stable suction pipeline 1 can be formed, thus well meeting the actual use requirements. This is a docking method of the present utility model, and other related pipeline docking methods can also be adopted in the actual use process.

[0038] As Figure 1As shown, during actual use, generally, the first docking convex tube 215 is connected to the suction bag hole through the suction pipeline 1 in a docking and communicating manner, and the second docking convex tube 216 is connected to the suction fan 3 through the suction pipeline 1. In this way, the normal suction and filtration requirements can be met, and thus the actual use requirements can be satisfied.

[0039] As Figures 2 to 5 shown, a positioning convex ring 2111 is provided on the inner wall of the cylinder cover 211. On the cavity wall of the filtration cavity 213 opposite to the positioning convex ring 2111, a convex tube part 2131 connected to the second docking convex tube 216 is provided. The filter element 22 is a cylindrical filter element. One end of the filter element 22 is sleeved on the convex tube part 2131, and the other end of the filter element 22 is embedded in the positioning convex ring 2111. A filtration gap 217 connected to the first docking convex tube 215 is reserved between the outer circumferential surface of the filter element 22 and the cavity wall of the filtration cavity 213. This not only helps improve the convenience and stability of the installation and positioning of the filter element 22, but also helps the filter element 22 have a more stable and reliable filtration effect, and can ensure that the suction generating device can generate a very stable and reliable suction force, thereby contributing to further improving the reliability and applicability of the suction generating device.

[0040] As Figure 4 shown, at least one U-shaped positioning strip 218 is sleeved on the outer circumferential surface of the cylinder body 212. The two ends of the U-shaped positioning strip 218 are bent outward to form fixing lugs 219 respectively. The use of the U-shaped positioning strip 218 not only facilitates manufacturing, but also helps to position the cylinder body 212 well. The fixing lugs 219 are used for welding and fixing on the heat-sealing film packaging equipment, which can conveniently and stably position the cylinder body 212, thereby helping to improve the convenience and stability of the installation and positioning.

[0041] The cylinder body 212 is a metal cylinder body, and the U-shaped positioning strip 218 is a metal strip. The middle part of the U-shaped positioning strip 218 is welded and fixed to the cylinder body 212 together, so as to meet the requirements of stable installation.

[0042] As Figure 5 shown, a reinforcing convex ring 2121 is provided on the mouth wall at the opening of the cylinder body 212. This can improve the structural strength of the opening of the cylinder body 212, thereby improving the anti-deformation ability of the opening of the cylinder body 212, and further facilitating the improvement of the covering strength of the cylinder cover 211, which helps to further improve the applicability of the suction generating device.

[0043] The above embodiments are the preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made shall fall within the protection scope of the present invention.
