Description

Technical Field

[0001] The utility model relates to the technical field of air expansion shafts, in particular to an automatic air deflation device for an air expansion shaft of a copper foil roll. Background Art

[0002] An inflatable shaft is a special winding and unwinding shaft, that is, a shaft whose surface can protrude after being inflated with high pressure, and a shaft whose surface part quickly retracts after being deflated is called an inflatable shaft.

[0003] Currently, there are many types, styles and specifications of gas shafts. For example, the fixed-slat gas shaft with Chinese patent number CN217807676U is provided. This technical solution is provided with a nut and a sleeve. When the outer wall of the slat is worn, the outer nut is rotated, causing the nut to drive the inner nut to rotate through the sleeve. The nut can then drive the slat to slide on the stud, thereby adjusting the position of the slat, thereby ensuring the distance the slat moves and the stability of the gas shaft during use. This utility model has a simple structure and is easy to use. It can effectively extend the service life of the slat-type gas shaft. However, this technology still has shortcomings in its specific implementation. Since the slat-type gas shaft relies solely on an independent airbag body, this type of gas shaft is unstable and prone to problems. When the airbag leaks, the entire gas shaft cannot be used, resulting in production failures. In addition, the air intake assembly used in the current gas shaft has a complex design, and the air intake and exhaust efficiency are slow, which brings unnecessary trouble to the use of the gas shaft and poor overall practical effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an automatic deflation device for a copper foil roll air expansion shaft, which has the advantages of strong stability and practicality, and solves the problems of poor stability and poor practical effect.

[0005] In order to achieve the above-mentioned purpose of strong stability and strong practicality, the present invention provides the following technical solutions: an automatic deflation device for a copper foil roll air-expanding shaft, comprising an air-expanding shaft body, wherein a plurality of telescopic mechanisms are arranged inside the air-expanding shaft body;

[0006] The telescopic mechanism includes a return spring, and multiple return springs are fixedly installed on the inner wall of the inflatable shaft body. The bottoms of the multiple return springs are fixedly connected to an adjusting block. A group of bearings are fixedly installed on the inner walls of the front and rear sides of the adjusting block. The inner walls of the two groups of bearings are fixedly connected to a rotating rod. The outsides of the two rotating rods are fixedly installed with a roller column. A silicone pad is bonded to the bottom of the adjusting block, and an adjusting airbag is provided between the bottom of the silicone pad and the inner bottom of the inflatable shaft body. A support plate extending to the outside of the inflatable shaft body is fixedly installed on the outside of the adjusting block, and a tensioning plate is fixedly installed on one end of the support plate extending to the outside of the inflatable shaft body.

[0007] Furthermore, the outside of the two roller columns are movably connected to the inner walls of the front and rear sides of the pneumatic shaft body, and the connection relationship is a sliding connection. The outside of the pneumatic shaft body is provided with a sliding groove adapted to the support plate, and the outside of the support plate is in a sliding connection relationship with the inner wall of the sliding groove.

[0008] Furthermore, limit blocks are fixedly installed on both sides of the left and right sides of the air inflation shaft body, and the interiors of the two limit blocks are provided with air intake mechanisms and exhaust mechanisms, and the separated surfaces of the limit blocks are fixedly installed with fixed shafts.

[0009] Furthermore, the air intake mechanism includes an air inlet, and the inside of the two limit blocks are fixedly installed with an air supply port, the bottoms of the two air supply ports are fixedly connected to an air supply pipe extending to the inside of the air-expanding shaft body, and one end of the two air supply pipes extending to the inside of the air-expanding shaft body is fixedly connected to an air expansion channel, and the outside of the air expansion channel is fixedly connected to multiple branch air pipes.

[0010] Furthermore, the exhaust mechanism includes an exhaust port, the separated surfaces of the two limit blocks are fixedly installed with an exhaust port, the separated surfaces of the two exhaust ports are threadedly connected with exhaust bolts, and the interiors of the two exhaust ports and the left and right ends of the inflation channel are fixedly connected with exhaust pipes.

[0011] Furthermore, one end of the branch air pipe is connected to the interior of the regulating airbag, and an I-shaped exhaust channel is opened inside the exhaust bolt.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] 1. The automatic deflation device of the copper foil roll air-expanding shaft is equipped with a telescopic mechanism. The adjusting airbag pushes the adjusting block on the top, so that the entire adjusting block and the tensioning plate can move up and down. At the same time, the silicone pad between the adjusting block and the adjusting airbag can avoid direct friction between the two, which can effectively protect the external surface of the adjusting airbag and prevent it from malfunctioning due to surface damage. At the same time, by setting up multiple adjusting airbags and tensioning plates, when one of the adjusting airbags leaks, the other airbags can continue to be used, thus ensuring the normal operation of the air-expanding shaft.

[0014] 2. The automatic deflation device of the copper foil roll air-expanding shaft is equipped with an air intake mechanism and an exhaust mechanism. The air delivery port can be connected to some inflation equipment to transmit the gas to the inflation channel through the air delivery pipe. Then, multiple branch air pipes can quickly transmit the high-pressure gas in the inflation channel to the interior of their respective regulating air bags to expand them, which is convenient for subsequent winding work and can greatly improve its winding efficiency. When it is necessary to discharge the internal gas, it is only necessary to rotate the exhaust bolts on the exhaust ports on both sides to move the air holes on the bolts from the inside of the exhaust port to the outside. Through the I-shaped exhaust channel inside the exhaust bolt, the effect of automatically discharging the inner wall gas can be achieved, which can greatly save labor and effectively improve the overall working efficiency of the equipment.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 In this embodiment, an automatic deflation device for an air-expanding shaft of a copper foil roll includes an air-expanding shaft body 1, and a plurality of telescopic mechanisms 2 are provided inside the air-expanding shaft body 1;

[0022] The telescopic mechanism 2 includes a return spring 201, and a plurality of return springs 201 are fixedly installed on the inner wall of the gas expansion shaft body 1. The bottom of the plurality of return springs 201 is fixedly connected to an adjusting block 202. A group of bearings 203 are fixedly installed on the inner walls of the front and rear sides of the adjusting block 202. There are two bearings in each group 203. The inner walls of the two groups of bearings 203 are fixedly connected to a rotating rod 204. The outer sides of the two rotating rods 204 are fixedly installed with roller columns 205. The outer sides of the two roller columns 205 are movably connected to the inner walls of the front and rear sides of the gas expansion shaft body 1, and the connection relationship is a sliding connection. When the adjusting block 202 moves up and down, the roller columns 205 on both sides can provide it with strong mobility. At the same time, it can also guide and support the movement of the adjusting block 202. The bottom of the adjusting block 202 is bonded with Silicone pad 207, an adjustment airbag 206 is arranged between the bottom of the silicone pad 207 and the inner bottom of the air-expanding shaft body 1, the silicone pad 207 can avoid direct friction between the two, and can effectively protect the outer surface of the adjustment airbag 206, so that it will not have any malfunction problems caused by damage to the surface. The outside of the adjustment block 202 is fixedly installed with a support plate 208 extending to the outside of the air-expanding shaft body 1, and the outside of the air-expanding shaft body 1 is provided with a sliding groove adapted to the support plate 208. The outside of the support plate 208 and the inner wall of the sliding groove are in a sliding connection relationship. The support plate 208 extends to one end of the air-expanding shaft body 1 and is fixedly installed with a tensioning plate 209, which can ensure that the support plate 208 will not shake or displace during the movement, so that the entire mechanism can maintain a high stability when performing the winding operation.

[0023] In the case implementation, limit blocks 3 are fixedly installed on the left and right sides of the air-inflating shaft body 1 to prevent the product from shifting during the winding process. The two limit blocks 3 are internally provided with an air intake mechanism 4 and an exhaust mechanism 5. The separated surfaces of the limit blocks 3 are fixedly installed with fixed shafts 6, which can flexibly disassemble or fix the equipment.

[0024] In the case implementation, the air intake mechanism 4 includes an air inlet 401, and the inside of the two limit blocks 3 are fixedly installed with an air supply port 401. The two air supply ports 401 can be connected to some inflation equipment. By inflating through the two air supply ports 401, the equipment can be operated more efficiently. The bottoms of the two air supply ports 401 are fixedly connected to an air supply pipe 402 extending to the inside of the air-expanding shaft body 1. The two air supply pipes 402 extend to one end of the air-expanding shaft body 1 and are fixedly connected to an inflation channel 403. The outside of the inflation channel 403 is fixedly connected to a plurality of branch air pipes 404, and one end of the branch air pipe 404 is connected to the inside of the regulating airbag 206. The gas is transmitted to the inflation channel 403 through the air supply pipe 402 through the two air supply ports 401, and then the plurality of branch air pipes 404 will quickly transmit the high-pressure gas in the inflation channel 403 to the inside of their respective regulating airbags 206, causing them to expand, facilitating subsequent winding work, and greatly improving their winding efficiency.

[0025] In the case implementation, the exhaust mechanism 5 includes an exhaust port 501, and the separated surfaces of the two limit blocks 3 are fixedly installed with the exhaust port 501. The interior of the two exhaust ports 501 and the left and right ends of the inflation channel 403 are fixedly connected with exhaust pipes 503. The adjustment airbag 206 can be connected to the interior of the inflation channel 403 and the exhaust port 501 area through the exhaust pipes 503 on both sides. The separated surfaces of the two exhaust ports 501 are threadedly connected with exhaust bolts 502, and an I-shaped exhaust channel is opened inside the exhaust bolts 502. When it is necessary to discharge the internal gas, it is only necessary to rotate the exhaust bolts 502 on the exhaust ports 501 on both sides to move the air holes on the bolts from the inside of the exhaust port 501 to the outside. Through the I-shaped exhaust channel inside the exhaust bolts 502, the effect of automatically discharging the inner wall gas can be achieved, which can greatly save labor and effectively improve the overall working efficiency of the equipment.

[0026] During implementation, follow these steps:

[0027] 1) First, fix the fixed shafts 6 on both sides of the air shaft to the winder;

[0028] 2) Then check whether it is firmly fixed;

[0029] 3) Connect the two gas ports 401 to the inflation device, causing the internal telescopic mechanism 2 to operate, expanding the multiple tensioning plates 209 outward;

[0030] 4) Finally, the product to be rolled is fixed on the plurality of tensioning plates 209 and the rolling work can be carried out.

[0031] To sum up, the automatic deflation device of the copper foil roll air-inflating shaft is provided with a telescopic mechanism 2, and the adjusting airbag 206 pushes the top adjusting block 202, so that the entire adjusting block 202 and the tensioning plate 209 can move up and down. At the same time, the silicone pad 207 between the adjusting block 202 and the adjusting airbag 206 can avoid direct friction between the two, and can effectively protect the outer surface of the adjusting airbag 206 so that it will not have malfunctions caused by damaged surface. At the same time, by providing multiple adjusting airbags 206 and tensioning plates 209, when one of the adjusting airbags 206 leaks, the other airbags can continue to be used, thus ensuring the normal operation of the air-inflating shaft, solving the problem that the slat-type air-inflating shaft relies only on an independent airbag body internally, but this type of air-inflating shaft is unstable and prone to problems. When the airbag leaks, the entire air-inflating shaft cannot be used, resulting in production failures.

[0032] In addition, by setting the air intake mechanism 4 and the exhaust mechanism 5, the air supply port 401 can be connected to some inflation equipment, and the gas is transmitted to the inflation channel 403 through the air supply pipe 402, and then the multiple branch air pipes 404 will quickly transmit the high-pressure gas in the inflation channel 403 to the interior of their respective regulating air bags 206, causing them to expand, facilitating the subsequent winding work, and greatly improving its winding efficiency. When it is necessary to discharge the internal gas, it is only necessary to rotate the exhaust bolts 502 on the exhaust ports 501 on both sides to move the air holes on the bolts from the inside of the exhaust port 501 to the outside. Through the I-shaped exhaust channel inside the exhaust bolt 502, the effect of automatically discharging the inner wall gas can be achieved, which can greatly save labor and effectively improve the overall working efficiency of the equipment, solving the problem that the air intake components used in the current air-expanding shafts are complex in design, have slow air intake and exhaust efficiency, bring unnecessary trouble to the use of the air-expanding shafts, and have poor overall practical effects.
