Description

Technical Field

[0001] This utility model relates to the field of rewinding machine processing technology, specifically a dust blowing device for edge trimming in a rewinding machine. Background Technology

[0002] In the metal processing industry, rewinding machines are often used to process items such as steel strips. During the process of trimming the steel, a large amount of dust is generated. This dust not only affects the quality of the product, but also easily affects the subsequent winding of the steel strip. Dust can be trapped during winding, causing defects on the surface of the steel strip, affecting subsequent transportation and use. At the same time, the dust generated during trimming also pollutes the working environment, endangers the health of operators, and causes dust to accumulate inside the equipment, accelerating the wear and tear of the equipment and increasing the maintenance and operating costs of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a dust blowing device for edge trimming in a rewinding machine, so as to solve the problem mentioned in the background art that the dust generated after edge trimming is easy to adhere to the outer surface of the steel strip, causing surface defects during subsequent winding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust blowing device for edge trimming of a rewinding machine, comprising an edge trimming machine, a first gear fixedly installed on one side surface of the edge trimming machine and located inside the edge trimming machine, a volute fixedly installed on one outer surface of the edge trimming machine, a sliding rod fixedly installed on one side surface of the edge trimming machine, and a housing fixedly installed on one outer surface of the edge trimming machine and located on one side of the volute. A rotating suction mechanism is provided between the housing and the edge trimming machine, which facilitates the adsorption of dust generated during edge trimming.

[0005] Preferably, the rotating suction mechanism includes: a second gear, which is rotatably installed inside the trimming machine, the second gear meshing with the first gear, and the diameter of the first gear being larger than the diameter of the second gear; an impeller is rotatably installed inside the volute, and the shaft of the impeller meshes with the second gear; and one end of the outer surface of the volute is in contact with the outer surface of the housing.

[0006] Using the above technical solution, when the edge trimming machine cuts and rewinds the released material, it will drive the second gear to rotate, and the rotation of the second gear will drive the first gear to rotate together. At the same time, through the diameter difference between the first gear and the second gear, the first gear can rotate faster, allowing the impeller to rotate at high speed to draw external air into the volute. This also allows the dust generated during the cutting of the steel strip to be absorbed into the inside of the housing, preventing the dust generated during edge trimming from spreading around and reducing surface defects caused by dust entrainment during subsequent rewinding.

[0007] Preferably, a drawer is slidably installed inside the box, and the outer surface of the drawer is in contact with the outer surface of the box. A snap-fit ​​pin is slidably installed on the outer surface of the box, and the outer surface of the snap-fit ​​pin is in contact with the outer surface of the drawer.

[0008] Using the above technical solution, the drawer can be limited and fixed by the snap-fit ​​pin, so that the adsorbed dust can be collected in the drawer. The drawer can also be fixed inside the box by the snap-fit ​​pin, which facilitates the collection of dust and allows it to be taken out for centralized treatment.

[0009] Preferably, a filter disc is slidably mounted on the outer surface of the drawer near the volute, and the outer surface of the filter disc is in contact with the outer surface of the drawer and the outer surface of the box respectively. A sliding suction mechanism is provided between the box and the sliding rod. The sliding suction mechanism allows the dust inlet to be flexibly adjusted, making it easier for dust to be adsorbed and reducing the probability of dust drifting out.

[0010] By adopting the above technical solution, the dust sucked into the drawer can be filtered by the filter disc inserted inside the drawer, and the probability of dust entering the volute and impeller can be reduced.

[0011] Preferably, the sliding suction mechanism includes: an air inlet, the air inlet having an inclined triangular design, and the air inlet being slidably mounted on the outer surface of the sliding rod, the outer surface of the air inlet having a threaded handle threadedly mounted thereon, one end of the threaded handle being in contact with the outer surface of the sliding rod, and an air duct being fixedly mounted on the outer surface of the air inlet, one end of the air duct being connected to the housing, the connection between the housing and the air duct having an arc-shaped design.

[0012] By adopting the above technical solution, the position and angle of the air intake can be easily adjusted by the threaded handle, so that the air intake can more easily pick up dust and allow the dust to move along the air duct. The arc design of the air duct and the box makes it easier for the dust and air to move.

[0013] Preferably, a cloth tube is fixedly installed on the outer surface of the edge trimming machine, and one end of the outer surface of the cloth tube is connected to the outer surface of the volute. A spraying mechanism is provided between the cloth tube and the edge trimming machine. The dust adhering to the outer surface of the steel strip can be blown off and blown towards the suction port through the spraying mechanism, thereby increasing the amount of dust absorbed and ensuring that no dust remains on the outer surface of the steel strip.

[0014] By adopting the above technical solution, dust can be easily blown off the steel belt and, in conjunction with the air intake, can be more easily sucked into and collected by the air intake, reducing the chance of dust scattering.

[0015] Preferably, the spraying mechanism includes: a hook plate, which is fixedly installed on one side surface of the edge trimming machine. The hook plate is inserted into one end of the fabric tube, and the fabric tube is a cuboid made of an airtight material. Velcro fasteners are uniformly sewn onto the outer surface of the fabric tube, and spray nozzles are uniformly sewn onto the outer surface of the fabric tube, with the openings of the spray nozzles facing the steel strip of the edge trimming.

[0016] Using the above technical solution, the cloth tube can be fixed and inserted by the hook plate, and the length of the cloth tube can be adjusted by the Velcro fastener. It can also be convenient to store the cloth tube, allowing the air ejected from the volute to push the cloth tube open and spray it out from the nozzle. This allows the nozzle and cloth tube to be flexibly arranged and stored, and can also blow away the dust generated by the cutting edge.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the dust blowing device for the edge trimming of the rewinding machine:

[0018] 1. As the trimming process proceeds, the trimming machine will rotate and rewind, driving the first gear to rotate as well. The second gear, which meshes with the first gear, will also rotate along with it. The difference in diameter between the second and first gears will increase the rotation speed of the impeller, allowing the volute to draw in more air. This will allow the dust generated during trimming to be sucked into the drawer for collection, preventing the steel strip from getting stuck with dust during winding and causing surface defects.

[0019] 2. As air and dust are drawn into the drawer and filtered by the filter disc, the air will be discharged from the volute to the outside, allowing the air to enter the cloth tube. The air will expand the cloth tube and allow the air to be discharged outward through the nozzle towards the dust, so that the dust adhering to the outer surface of the steel strip can be easily blown off, reducing the chance of dust remaining on the outer surface of the steel strip.

[0020] 3. The edge trimming machine can clamp steel strips of different sizes and widths. Before processing, the fabric tube needs to be pulled open so that it can be hung on the hook plate on the other side. This makes it easy to unfold and retract the fabric tube. The Velcro fasteners evenly distributed on the outer surface of the fabric tube can effectively control the length of the fabric tube, so that the fabric tube will not droop due to being too long after unfolding, making it easy to unfold and store the fabric tube.

[0021] 4. When trimming the steel strip, the threaded handle needs to be rotated to separate it from the sliding rod, allowing the suction port to move freely on the sliding rod and adjust its angle. This allows the suction port to be adjusted in position and angle to extract more dust during steel strip trimming and reduce the chance of dust scattering. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a dust blowing device for edge trimming of a rewinding machine, including an edge trimming machine 1. A first gear 2 is fixedly installed on one side surface of the edge trimming machine 1 and is located inside the edge trimming machine 1. A volute 4 is fixedly installed on one outer surface of the edge trimming machine 1. A sliding rod 14 is fixedly installed on one side surface of the edge trimming machine 1. A housing 6 is fixedly installed on one outer surface of the edge trimming machine 1 and is located on one side of the volute 4. A rotating suction mechanism is provided between the housing 6 and the edge trimming machine 1. The rotating suction mechanism facilitates the adsorption of dust generated during edge trimming. The rotating suction mechanism includes: a second gear 3, which is rotatably installed inside the edge trimming machine 1. The second gear 3 meshes with the first gear 2, and the diameter of the first gear 2 is larger than the diameter of the second gear 3. An impeller 5 is rotatably installed inside the volute 4, and the shaft of the impeller 5 meshes with the second gear 3. One outer surface of the volute 4 is in contact with the outer surface of the housing 6.

[0031] During winding and trimming, the trimming machine 1 will rotate, driving the first gear 2 to rotate, which in turn allows the second gear 3, which meshes with the first gear 2, to rotate. Through the diameter difference between the second gear 3 and the first gear 2, the impeller 5 can rotate more rapidly, allowing the volute 4 to draw in more air. This allows air and dust to be drawn into the housing 6 together, preventing dust from falling onto the steel belt after trimming and reducing surface defects caused by dust entanglement after trimming and winding.

[0032] A drawer 7 is slidably installed inside the box 6, and the outer surface of the drawer 7 is in contact with the outer surface of the box 6. A latching pin 9 is slidably installed on the outer surface of the box 6, and the outer surface of the latching pin 9 is in contact with the outer surface of the drawer 7.

[0033] The dust can be collected through drawer 7. At the same time, the drawer 7 can be fixed and restricted by the buckle 9 inserted into the inside of the box 6, so that the dust can be collected in the drawer 7 and can be easily removed for cleaning.

[0034] A filter disc 8 is slidably installed on the outer surface of the drawer 7 near the volute 4, and the outer surface of the filter disc 8 is in contact with the outer surface of the drawer 7 and the outer surface of the box 6 respectively. A sliding suction mechanism is provided between the box 6 and the sliding rod 14. The dust inlet can be flexibly adjusted through the sliding suction mechanism, so that the dust can be more easily absorbed and the probability of dust drifting out can be reduced.

[0035] The filter disc 8 inserted into the drawer 7 can filter and collect the inhaled dust, and the filter disc 8 can be easily removed and replaced, ensuring that the dust can remain inside the drawer 7, and that the air can collect the dust through the air intake 15, so that the dust will not spread around, reducing the chance of dust accumulating inside the device and preventing dust from spreading around and causing pollution.

[0036] The sliding suction mechanism includes: an air inlet 15, which is an inclined triangular design and is slidably mounted on the outer surface of a sliding rod 14. A threaded handle 16 is threadedly mounted on the outer surface of the air inlet 15, and one end of the threaded handle 16 is in contact with the outer surface of the sliding rod 14. An air duct 17 is fixedly mounted on the outer surface of the air inlet 15, and one end of the air duct 17 is connected to the housing 6. The connection between the housing 6 and the air duct 17 is an arc-shaped design.

[0037] When cutting, simply adjust and turn the threaded handle 16 to fix the position of the air inlet 15, allowing the air inlet 15 to move and adjust flexibly on the outer surface of the sliding rod 14. The angle of the air inlet 15 can also be adjusted so that the air inlet 15 can be close to the cutting point, allowing the sucked dust and air to enter the interior of the drawer 7 along the air duct 17. The inclined design at the connection between the cabinet 6 and the air duct 17 allows the air and dust to move more smoothly.

[0038] A cloth cylinder 10 is fixedly installed on the outer surface of the edge trimming machine 1, and one end of the outer surface of the cloth cylinder 10 is connected to the outer surface of the volute 4. A spraying mechanism is provided between the cloth cylinder 10 and the edge trimming machine 1. The dust adhering to the outer surface of the steel strip can be blown off and blown toward the suction port 15 through the spraying mechanism, thereby increasing the amount of dust absorbed and preventing dust from remaining on the outer surface of the steel strip.

[0039] The rotation of impeller 5 and the intake of volute 4 allow air dust to be filtered and discharged into cloth cylinder 10. The cloth cylinder 10 and the blow nozzle 13 can blow air outward. The inclined design of the blow nozzle 13 blows away the dust on the outer surface of the steel belt, and in conjunction with the suction port 15, it is sucked up, so that the dust on the outer surface of the steel belt can be blown off more easily, and the dust will not remain on the outer surface of the steel belt.

[0040] The spraying mechanism includes: a hook plate 12, which is fixedly installed on one side surface of the edge trimming machine 1. The hook plate 12 is inserted into one end of the cloth tube 10. The cloth tube 10 is a cuboid made of an airtight material. Velcro fasteners 11 are evenly sewn onto the outer surface of the cloth tube 10. Spray nozzles 13 are evenly sewn onto the outer surface of the cloth tube 10, and the openings of the spray nozzles 13 face the steel strip being trimmed.

[0041] When the edge cutting machine clamps steel strips of different widths, the length of the fabric tube 10 can be fixed and limited by the Velcro fastener 11, and the fabric tube 10 can be fixed by the hook plate 12. The airtight material of the fabric tube 10 prevents air leakage and allows for easy folding and storage.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
