[0001] The utility model belongs to the technical field of liquid filling, and in particular relates to an electrostatic dust removal device used for the incision of packaging materials of liquid filling equipment. Background Art

[0002] In the filling process of liquids such as milk, in order to prevent paper scraps on the cut edge of the packaging material from contaminating the filling liquid, the paper scraps and dust on the cut edge of the packaging material need to be removed before filling.

[0003] The existing method of cleaning the edge of the packaging material is to directly contact the rubber lip with the edge of the packaging material, and use the rubber lip to overcome the electrostatic force between the paper scraps and dust and the packaging material cut to remove the paper scraps and dust from the packaging material cut. However, due to the fast movement speed of the packaging material, the friction between the packaging material and the rubber lip will cause the rubber lip to wear out quickly and fail, thus failing to work normally. If the rubber lip is not found and replaced in time, the quality of liquid food filling will be affected. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Combination Figure 1 and Figure 2 As shown, this embodiment discloses an electrostatic dust removal device for liquid filling equipment such as milk packaging material cutting, including a blowing pipe 1. The packaging material is Figure 1 The air blowing pipe 1 is arranged at intervals on the side end of the packaging material for transmission in the middle X-axis direction. The air blowing end of the air blowing pipe 1 is located above the packaging material incision 3, and is used to output positive ion airflow and negative ion airflow to the packaging material to neutralize the electrostatic charge on the packaging material and blow away impurities on the packaging material.

[0031] Specifically, the positive ion airflow and negative ion airflow output from the blowing pipe will blow toward the location of the packaging material cutout, which can neutralize the electrostatic charge generated when the paper scraps and dust come into contact with the packaging material cutout, and at the same time, the paper scraps and dust can be blown away from the packaging material, so that the fallen paper scraps and dust can be collected by the suction pipe. In this way, the positive ion airflow and negative ion airflow can be used to separate the paper scraps and dust from the packaging material without direct contact with the packaging material, and quickly collected by the suction pipe, which can not only avoid the loss caused by the existing rubber lip needing to be in direct contact with the packaging material for a long time, and improve the durability and service life of the electrostatic dust removal device, but also prevent the fallen paper scraps and dust from contacting the packaging material cutout again, and improve the cleaning effect of paper scraps and dust.

[0032] In other embodiments, the position of the blowing end of the blowing pipe and the position of the suction end of the suction pipe can be adaptively adjusted according to the position of the packaging material incision. For example, the suction pipe is located above the packaging material incision and the blowing pipe is located below the packaging material incision, which can also achieve the purpose of electrostatic dust removal of the packaging material incision.

[0033] Combination Figure 2 As shown, in this embodiment, the electrostatic precipitator further includes a high-frequency ion air nozzle 4. The air outlet end of the high-frequency ion air nozzle 4 is connected to the air inlet end of the air blowing pipe 1, and the high-frequency ion air nozzle can continuously and stably provide positive ion airflow and negative ion airflow to the air blowing pipe. The high-frequency ion air nozzle can be connected to an ion generator, which ionizes molecules in the air by using high voltage to generate a large number of positive ions and negative ions. The high-frequency ion air nozzle 4 provides positive ion airflow and negative ion airflow to the air blowing pipe by connecting to the ion generator.

[0034] Preferably, the high-frequency ion nozzle 4 is detachably connected to the blowing tube 1, which can improve the convenience of replacing the blowing tube. Specifically, by changing the cross-sectional area of ​​the blowing end to adapt to different packaging material cut thicknesses, targeted electrostatic dust removal operations can be achieved, thereby improving the efficiency of electrostatic dust removal.

[0035] Combination Figure 1 and Figure 2 As shown, the electrostatic dust removal device also includes an air suction pipe 2 and a suction fan 5. The suction fan 5 is connected to the air suction pipe 2, and the air suction pipe 2 is arranged at the other end of the packaging material opposite to the blowing pipe 1. Specifically, the air suction end of the air suction pipe 2 is located below the packaging material cutout 3, and is used to collect impurities blown off the dust removal part. The suction fan can provide negative pressure suction for the air suction pipe, so as to facilitate the absorption of dust and paper scraps dropped from the packaging material cutout. Among them, a gap is reserved between the blowing pipe 1 and the air suction pipe 2 and the packaging material cutout 3.

[0036] Among them, in this embodiment, the suction fan is a centrifugal fan. Of course, in other embodiments, a vacuum pump can also be connected to the suction pipe, and the same effect of separating dust and paper scraps from the cut of the packaging material can be achieved.

[0037] Furthermore, in this embodiment, each cut of the packaging material corresponds to a blowing pipe and a suction pipe. Of course, in other embodiments, the number of blowing pipes and the number of suction pipes can also be adjusted according to actual needs.

[0038] Combined with Figure 1 and Figure 2 As shown, the electrostatic dust removal device further includes a storage box 6. The storage box 6 is communicated with the dust discharge port of the suction fan 5. By discharging the air extracted by the suction fan through the storage box, dust and paper scraps can be collected, and the dust and paper scraps can be centrally cleaned, so that the electrostatic dust removal device achieves the purpose of being green, environmentally friendly and pollution-free.

[0039] Preferably, the suction fan 5 is detachably connected to the suction pipe 2, which can further improve the simplicity of replacing the suction pipe.

[0040] Combined with Figure 1 and Figure 2 As shown, in this embodiment, the electrostatic dust removal device further includes a positioning frame 7. Among them, the positioning frame 7 can be in a "C" shape. The blowing pipe passes through the top plate of the positioning frame and is connected to the positioning frame, and the suction pipe passes through the bottom plate of the positioning frame and is connected to the positioning frame, so that the positioning frame can respectively position the blowing end and the suction end. Through the positioning frame 7, the blowing pipe 1 and the suction pipe 2 are respectively arranged directly above and directly below the packaging material. At the same time, there are gaps between the blowing end of the blowing pipe 1 and the suction end of the suction pipe 2 and the packaging material respectively, so that the operations of blowing away paper scraps and dust and the collection operation can be completed without direct contact.

[0041] In other embodiments, the shape of the positioning frame can be adjusted. For example, an "I" shape can be adopted, and the positioning frame can also be used to fix the positions of the blowing end and the suction end respectively.

[0042] Preferably, the top plate of the positioning frame 7 is detachably connected to the blowing pipe 1, and the bottom plate of the positioning frame 7 is detachably connected to the suction pipe 2, so that the positioning frame can improve the simplicity of positioning the blowing pipe and the suction pipe.

[0043] Combined with Figure 1 and Figure 2 As shown, preferably, the positioning frame 7 in this embodiment adopts a split structure. In this embodiment, the number of positioning frames is two. The two positioning frames are respectively located at the two cut positions of the packaging material, and both positioning frames are provided with suction pipes and blowing pipes, so that the working efficiency of electrostatic dust removal of the packaging material can be improved.

[0044] Preferably, a plurality of positioning frames are arranged along the moving direction of the packaging material, and the plurality of positioning frames are arranged at intervals. By utilizing the suction pipe and the blowing pipe respectively arranged in each positioning frame, the electrostatic dust removal effect of the packaging material during high-speed transmission can be ensured.

[0045] Furthermore, the blowing pipe 1 and the suction pipe 2 respectively adopt a one-to-many structure, that is, the blowing pipe 1 is provided with a connecting end and multiple blowing ends, and the suction pipe is provided with a connecting end and multiple suction ends. This can reduce the number of high-frequency ion nozzles and the number of suction fans, thereby achieving the technical effect of reducing the cost of the electrostatic dust removal device.

[0046] Combination Figure 1 and Figure 2 As shown, the electrostatic dust removal device also includes a moving frame 8. The moving frame 8 is arranged along the Y-axis direction, and the positioning frame 7 is connected to the moving frame 8. Among them, the positioning frame 7 can be moved on the moving frame 8 relative to the packaging material incision 3. Specifically, a first sliding groove 81 is provided on the moving frame 8, and a first positioning hole is provided on the positioning frame 7. The positioning frame can reciprocate linearly along the Y-axis direction on the moving frame, and then the first positioning bolt passes through the first sliding groove and the first positioning hole respectively, and is threadedly connected with the first nut to achieve adjustable position between the positioning frame and the moving frame, so that the distance between the split positioning frames can be adjusted according to the width of the packaging material, thereby achieving the effect of electrostatic dust removal for packaging materials of different widths.

[0047] Combination Figure 1 and Figure 2 As shown, the electrostatic dust removal device also includes a fixed frame 9. The fixed frame 9 is connected to the shell that protects the electrostatic dust removal device, that is, the position of the fixed frame is fixed, and the movable frame 8 can be slidably connected along the fixed frame 9. Specifically, a second positioning hole is provided on the movable frame 8, and a second sliding groove 91 along the Z-axis direction is provided on the fixed frame 9. The positioning frame 7 can reciprocate linearly along the Z-axis direction. After moving to the required height of the positioning frame 7, the second positioning bolt 92 passes through the second sliding groove 91 and the second positioning hole respectively and is threadedly connected with the second nut 93. Then, the height of the suction pipe and the blowing pipe can be adjusted respectively according to the transmission height of the packaging material, thereby achieving the effect of adjusting the packaging material accordingly according to different transmission heights.

[0048] In addition, combined Figure 2As shown, in this embodiment, the electrostatic dust removal device also includes an air filter 10 and a wind source. The wind source can be a compressed air machine, the air inlet end of the air filter is connected to the compressed air machine, and the air outlet end of the air filter is connected to the high-frequency ion wind nozzle, which is used to filter out dust, oil and other impurities in the gas in the compressed air machine, and prevent the impurities from combining with the positive ion airflow and negative ion airflow generated by the high-frequency ion wind nozzle to reduce the amount of positive ions and negative ions, thereby achieving the effect of ensuring the electrostatic dust removal efficiency of the packaging material cutting edge. In addition, the air filter can also prevent impurities from clogging the blowing pipe, the suction pipe and the high-frequency ion wind nozzle.

[0049] Of course, in other embodiments, the wind source may also be a fan, which can also provide power for the positive ion airflow and negative ion airflow generated by the high-frequency ion wind nozzle.
