Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foil winding machine, in particular to a dust blowing mechanism for foil winding machine. BACKGROUND

[0002] The foil winding machine is also named foil coil winding machine or foil winding machine, which is a special equipment for winding foil coil of transformer. The foil winding machine series adopts PLC automatic control variable frequency stepless speed regulation system, photoelectric hydraulic pressure deviation rectifying system, automatic welding mechanism and other automatic control functions. The welding quality of the transformer winding foil is ensured, and the loss of the transformer is greatly reduced.

[0003] At present, the foil winding machine generally comprises a foil unwinding device, a material guiding device, a tensioning device and a winding device. The foil unwinding device supports the wound foil and makes it rotate and unwind. Then the material guiding device sends the foil to the winding device. During the sending process, the tensioning device generates a small tension on the strip-shaped foil, thereby improving the tightness of the wound foil. During the process of guiding the foil by the material guiding device, the foil needs to be blown to remove the dust on the surface of the foil, thereby preventing excessive dust from interfering with the normal operation of the transformer.

[0004] However, in the existing related technology, the blowing of the foil is generally only performed by setting a gas blowing pipe above the foil. When dust of different particle sizes falls on the surface of the foil, the simple gas blowing operation has poor dust removal effect. CONTENT OF THE INVENTION

[0005] In order to overcome the shortcomings of the prior art, the present application provides a dust blowing mechanism for foil winding machine.

[0006] The present application adopts the following technical scheme: a dust blowing mechanism for foil winding machine is arranged between the tensioning device and the winding device of the foil winding machine and located outside the foil. The dust blowing mechanism comprises a support and a shell arranged on the top of the support. The foil passes through the shell. A fixed plate is arranged on the inner wall of the shell. Two support plates are arranged on the fixed plate and correspond to the two sides of the foil respectively. A plurality of first gas blowing heads are arranged on the bottom of one of the support plates. A plurality of second gas blowing heads are arranged on the top of the other support plate. A gas supply pipe is arranged on the outer wall of the shell. The gas supply pipe passes through the fixed plate and the support plates in sequence and supplies gas to the first gas blowing heads and the second gas blowing heads.

[0007] The first gas blowing head and the second gas blowing head are arranged obliquely. The oblique direction of the first gas blowing head is opposite to the oblique direction of the second gas blowing head.

[0008] Optionally, one side of the outer wall of the shell is provided with an inlet, and the other side of the outer wall of the shell is provided with an outlet, the foil passes into the inlet and passes out of the outlet, and the height of the inlet is greater than the height of the outlet.

[0009] Optionally, the fixed plate is connected to the inner wall of the shell by bolts, and the support plate is welded to the fixed plate and perpendicular to the fixed plate.

[0010] Optionally, one end of the gas conveying pipe is in communication with an external gas source, and the other end of the gas conveying pipe extends into the fixed plate and the support plate and is in communication with the first gas blowing head and the second gas blowing head.

[0011] Optionally, two scrapers made of felt are arranged between the two support plates, the scrapers are used to sweep the surface of the foil, and the first gas blowing head and the second gas blowing head are arranged between the two scrapers.

[0012] Optionally, a gap exists between the scraper near the inlet and the outer wall of the foil, and the scraper near the outlet is attached to the outer wall of the foil.

[0013] Compared with the prior art, in the present application, the first gas blowing head and the second gas blowing head are inclined in different directions to blow the foil, so that the foil can be slightly deformed in the shell, thereby loosening the dust adhering to the surface of the foil during the deformation, and thereby improving the blowing effect of the first gas blowing head and the second gas blowing head on the foil.

[0018] In the following, the present application will be further described in conjunction with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0019] As Figures 1-3 shown, the dust blowing mechanism for the foil winding machine is arranged between the tensioning device 1 and the winding device 2 of the foil winding machine and located outside the foil material 3, which comprises a support 4 and a shell 5 arranged on the top of the support 4, the foil material 3 passes through the shell 5, a fixed plate 51 is arranged on the inner wall of the shell 5, two support plates 52 are arranged on the fixed plate 51, and the two support plates 52 are respectively and one-to-one arranged on the two sides of the foil material 3, the bottom of one support plate 52 is provided with a plurality of first air blowing heads 6, and the top of the other support plate 52 is provided with a plurality of second air blowing heads 7, a gas supply pipe 53 is arranged on the outer wall of the shell 5, the gas supply pipe 53 passes through the fixed plate 51 and the support plate 52 in sequence and supplies gas to the plurality of first air blowing heads 6 and the plurality of second air blowing heads 7; the first air blowing head 6 and the second air blowing head 7 are arranged obliquely, and the oblique direction of the first air blowing head 6 is opposite to the oblique direction of the second air blowing head 7.

[0020] The first air blowing head 6 and the second air blowing head 7 are arranged in the shell 5, the first air blowing head 6 can blow the upper surface of the foil material 3, the second air blowing head 7 can blow the lower surface of the foil material 3, and the plurality of first air blowing heads 6 and the plurality of second air blowing heads 7 extend along the length direction of the support plate 52. Since the oblique directions of the first air blowing head 6 and the second air blowing head 7 are opposite, the air flow blown by the first air blowing head 6 and the second air blowing head 7 will generate different direction thrust on the surface of the foil material 3, so that the foil material 3 will produce a small amount of deformation, that is, the foil material 3 will be in a wave shape in the shell 5, so that the dust on the surface of the foil material 3 will be loosened, and then the dust will be blown away by the first air blowing head 6 or the second air blowing head 7, which significantly improves the blowing effect of the dust.

[0021] One side of the outer wall of the shell 5 is provided with an inlet 54, and the other side of the outer wall of the shell 5 is provided with an outlet 55, the foil material 3 enters from the inlet 54 and exits from the outlet 55, and the height of the inlet 54 is greater than the height of the outlet 55. Since the size of the inlet 54 is greater than the size of the outlet 55, when the first air blowing head 6 and the second air blowing head 7 blow the dust away from the shell 5, the dust is more easily blown out from the inlet 54 to the outside of the shell 5, so that the dust can be prevented from secondary pollution to the foil material 3 to the greatest extent, and the foil material 3 can keep the surface clean when entering the winding device 2.

[0022] The fixed plate 51 is connected with the inner wall of the shell 5 by bolts 510, and the support plate 52 is welded on the fixed plate 51 and perpendicular to the fixed plate 51, so that the two support plates 52 can reliably be arranged on the upper and lower sides of the foil material 3 respectively and can reliably blow the surface of the foil material 3.

[0023] One end of the gas conveying pipe 53 is communicated with an external gas source, and the other end of the gas conveying pipe 53 extends in the fixed plate 51 and the support plate 52 and is communicated with the plurality of first air blowing heads 6 and the plurality of second air blowing heads 7. The gas conveying pipe 53 extends in the shell 5 through the fixed plate 51 and the support plate 52, avoiding the naked state of the gas conveying pipe 53 in the shell 5, preventing the air flow blown by the first air blowing head and the second air blowing head 7 from interfering with the gas conveying pipe 53, and further ensuring the stability of the gas conveying operation of the gas conveying pipe 53. Further, the discharge of dust by the gas conveying pipe 53 is also prevented from being interfered.

[0024] Two scrapers 8 made of felt are arranged between the two support plates 52, and the scrapers 8 are used to scrape the surface of the foil material 3. The first air blowing head 6 and the second air blowing head 7 are arranged between the two scrapers 8. During the conveying of the foil material 3 in the shell 5, the foil material 3 will first pass through one scraper 8 for scraping, then pass through the first air blowing head 6 and the second air blowing head 7 for blowing, and finally pass through the other scraper 8 for scraping. In this way, under the dual action of air flow blowing and scraper 8 scraping, the dust on the surface of the foil material 3 can be effectively removed.

[0025] There is a gap 80 between the scraper 8 close to the inlet 54 and the outer wall of the foil material 3, and the scraper 8 close to the outlet 55 is attached to the outer wall of the foil material 3. In this way, the scraper 8 close to the inlet 54 can scrape off the larger dust on the surface of the foil material 3, and the scraper 8 close to the outlet 55 can scrape off the smaller dust that cannot be blown off by the first air blowing head and the second air blowing head 7. The stepped scraping operation can improve the scraping effect while preventing scratches on the surface of the foil material 3 during the scraping or blowing process to the greatest extent.

[0026] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art based on the present application are within the scope of the present application.
