Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal device for paper aluminum film packaging. Background Technology

[0002] Paper aluminum film, as a composite material that combines the flexibility of paper and the barrier properties of aluminum film, has a wide range of applications in packaging, construction, electronics and other fields. In the production process, paper aluminum film usually needs to be slit to meet the specific material size requirements of different products or equipment. The slit process is to cut the wide paper aluminum film into multiple narrow strips of material by a slit machine.

[0003] During the paper-aluminum film slitting process, a certain amount of debris and dust is inevitably generated due to the friction and cutting action between the high-speed rotating slitting blade and the material. This debris and dust not only affect the cleanliness of the production environment, but may also cause wear and tear on production equipment and reduce production efficiency. More importantly, they may contain substances harmful to human health, posing a potential threat to the health of operators. Although existing dust removal equipment can reduce the flying of debris and dust to some extent, it is difficult to effectively capture these fine, high-speed flying debris and dust generated by the high-speed rotating slitting blade due to the small particle size and high speed of the debris and dust, as well as the design and structural limitations of existing dust removal equipment. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for paper aluminum film packaging, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust removal device for paper-aluminum film packaging includes a slitting machine. A negative pressure vacuum cleaner is fixedly installed on the rear side of the slitting machine. The negative pressure vacuum cleaner is electrically connected to an external main controller via a connecting cable. Multiple guide rollers are movably installed on the front side of the slitting machine. A slitting roller is also movably installed above one of the guide rollers. One end of the guide roller and the slitting roller are respectively connected to a motor on the front side of the slitting machine via a transmission mechanism. Two fixed sleeves are fixedly installed on the outer side of the slitting roller. A slitting blade is also fixedly installed on the slitting roller between the two fixed sleeves. A lower dust collection disc is also fixedly installed on the slitting machine below the slitting roller. Upper dust collection hoods are fixedly installed on the outer sides of the two fixed sleeves respectively. A connecting pipe is movably installed on one side of the upper dust collection hood.

[0007] As a further preferred embodiment of this utility model, side plates are fixedly installed on both sides of the lower dust collection disc. The side of the side plate opposite to the lower dust collection disc is fixedly installed inside the slitting machine. A first connector is fixedly installed at the lower end of the lower dust collection disc. The channel inside the first connector communicates with the inner cavity of the lower dust collection disc. The first connector is fixedly connected to the output end of the negative pressure vacuum cleaner through a hose. The lower dust collection disc is set below the slitting roller, and in conjunction with the negative pressure vacuum cleaner, it can collect the debris and dust generated and falling during slitting.

[0008] As a further preferred embodiment of this utility model, a connecting ring is fixedly installed on one side of the upper dust hood, and multiple connecting rods are fixedly connected to the inner side of the upper dust hood. The upper dust hood is inserted and installed on the outside of one of the fixed sleeve blocks, and the connecting ring is fixedly connected to one side of the fixed sleeve block by screws.

[0009] As a further preferred embodiment of this utility model, a positioning groove is provided on the inner side of the upper dust suction hood, and multiple ball bearings are rotatably installed in the positioning groove, and a sleeve is also inserted inside the upper dust suction hood.

[0010] As a further preferred embodiment of this utility model, a positioning groove is also provided on the outer side of the sleeve, and multiple ball bearings are rotatably installed in the positioning groove.

[0011] As a further preferred embodiment of this utility model, the connecting tube has a hollow internal structure. One side of the connecting tube extends through the channel between the upper dust hood and the sleeve to the upper dust hood and is fixedly installed with two retaining rings. The two retaining rings rotate in their respective positioning grooves. A second connector is also fixedly installed on the outside of the connecting tube. The second connector is connected to the input end of the negative pressure vacuum cleaner through a rigid pipe. An upper dust hood is set on the outside of the fixed sleeve, and the dust suction chamber on one side of the upper dust hood is close to the cutting blade. Thus, when the material is cut, some of the debris and dust generated during the cutting process can be absorbed and treated in a timely manner.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the lower dust collection plate can collect some of the falling debris and dust. An upper dust collection hood is installed on each of the two fixing blocks used to fix the slitting blade. Together with the inner sleeve and connecting pipe of the dust collection hood, the slitting blade can instantly absorb the debris and dust generated during the slitting of the paper-aluminum film without affecting its rotation. This effectively reduces the situation where some debris and dust are quickly thrown out and cannot be effectively collected due to the high-speed rotation of the slitting blade, thus ensuring the efficiency of debris and dust handling during the slitting of the paper-aluminum film.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-6 As shown, the present invention provides a dust removal device for paper aluminum film packaging, including a slitting machine 1. A negative pressure vacuum cleaner 2 is fixedly installed on the rear side of the slitting machine 1. The negative pressure vacuum cleaner 2 is electrically connected to an external main controller via a connecting line. Multiple guide rollers 3 are movably installed on the front side of the slitting machine 1. A slitting roller 4 is also movably installed on the slitting machine 1 above one of the guide rollers 3. One end of the guide roller 3 and the slitting roller 4 are respectively connected to a motor on the front side of the slitting machine 1 via a transmission mechanism. Two fixed sleeves 5 are fixedly installed on the outer side of the slitting roller 4. A slitting blade 6 is also fixedly installed on the slitting roller 4 between the two fixed sleeves 5. A lower dust collection disc 7 is also fixedly installed on the slitting machine 1 below the slitting roller 4. Upper dust collection covers 8 are fixedly installed on the outer side of the two fixed sleeves 5 respectively. A connecting pipe 9 is movably installed on one side of the upper dust collection cover 8.

[0023] like Figure 1 , Figure 3As shown, side plates 10 are fixedly installed on both sides of the lower dust collection plate 7. The side of the side plate 10 opposite to the lower dust collection plate 7 is fixedly installed inside the slitting machine 1. A first connector 11 is fixedly installed at the lower end of the lower dust collection plate 7. The channel inside the first connector 11 communicates with the inner cavity of the lower dust collection plate 7. The first connector 11 is fixedly connected to the output end of the negative pressure vacuum cleaner 2 through a hose. The lower dust collection plate 7 is set below the slitting roller 4. With the setting of the negative pressure vacuum cleaner 2, the debris and dust generated and falling during slitting can be collected.

[0024] like Figures 1-2 , Figures 4-6 As shown, a connecting ring 12 is fixedly installed on one side of the upper dust hood 8. Multiple connecting rods 13 are fixedly connected to the inner side of the upper dust hood 8. The upper dust hood 8 is inserted and installed on the outside of one of the fixed sleeve blocks 5, and the connecting ring 12 is fixedly connected to one side of the fixed sleeve block 5 by screws. A positioning groove 14 is provided on the inner side of the upper dust hood 8, and multiple ball bearings 16 are rotatably installed in the positioning groove 14. A sleeve 15 is also inserted inside the upper dust hood 8, and a positioning groove 14 is also provided on the outer side of the sleeve 15, with multiple ball bearings 16 rotatably installed in the positioning groove 14. The connecting tube 9 has a hollow internal structure. One side of the connecting pipe 9 extends through the channel between the upper dust hood 8 and the sleeve 15 into the upper dust hood 8 and is fixedly installed with two retaining rings 17. The two retaining rings 17 rotate in the corresponding positioning grooves 14 respectively. A second connector 18 is also fixedly installed on the outside of the connecting pipe 9. The second connector 18 is connected to the input end of the negative pressure vacuum cleaner 2 through a rigid pipe. An upper dust hood 8 is set on the outside of the fixed sleeve block 5, and the dust suction chamber on the lower side of the upper dust hood 8 is close to the cutting blade 6. Thus, when cutting materials, some of the debris and dust generated during cutting can be absorbed and treated in time.

[0025] It should be noted that this utility model is a dust removal device for paper aluminum film packaging. When the slitting machine 1 is slitting the paper aluminum film, the slitting roller 4 drives the fixed sleeve block 5 and the slitting blade 6 to rotate at high speed. Simultaneously, the fixed sleeve block 5 drives the upper dust suction hood 8 to rotate as well. Since the connecting pipe 9 is connected to the input end of the negative pressure vacuum cleaner 2 through an external rigid pipe, the axial movement of the connecting pipe 9 can be restricted. This allows the upper dust suction hood 8 and the sleeve 15 to rotate on the corresponding retaining ring 17 through the inner positioning groove 14, thereby ensuring that the rotation of the upper dust suction hood 8 does not affect the connection between the second connector 18 and the pipe. When the paper aluminum film comes into contact with the slitting blade 6 for cutting, some debris and dust will be generated at the cutting point of the paper aluminum film. Some of the dust will be sucked in by the upper dust hood 8 located on both sides of the slitting blade 6. The debris and dust will then enter the negative pressure vacuum cleaner 2 through the upper dust hood 8, the connecting pipe 9, the second connector 18, and the external pipe for collection. In addition, some debris and dust that are not collected by the upper dust hood 8 will gradually fall due to gravity. At this time, the lower dust disk 7 will collect the falling dust from below and suck it into the negative pressure vacuum cleaner 2 through the external pipe for collection and processing.

[0026] 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
