Description

Technical Field

[0002] The film blowing machine is a piece of equipment used for plastic processing, mainly used to produce plastic film. This machine heats and melts plastic particles or granular plastics, then blows air through the extruder head to expand them into a film, and finally cools and reels them.

[0003] In the prior art, when the plastic film produced by the film blowing machine is wound, in order to improve the winding quality, pressure is usually applied during winding to ensure that the plastic film is tightly wound. However, after the multi-layer winding is completed, the pressure caused by the plastic film will fit more closely with the winding roller used as the drive, which makes it more laborious to remove the plastic film, affecting the processing efficiency. Therefore, we propose a film blowing machine winding structure to solve this problem.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0021] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0022] The embodiment of the present application discloses a winding structure of a film blowing machine.

[0023] Reference Figure 1-Figure 4 A film blowing machine winding structure comprises: a bottom plate 1, a bracket 2 is fixedly connected to the top of the bottom plate 1, a motor 3 is fixedly connected to the outer surface of the bracket 2, an output end of the motor 3 slides through the bracket 2, and a rotating shaft 4 is fixedly connected to the output end of the motor 3; a winding component 5, the winding component 5 is fixedly connected to the end surface of the rotating shaft 4, the winding component 5 comprises a first side frame 501 and a winding tube 507, a hollow tube 502 is fixedly connected to the outer surface of the first side frame 501, a plurality of grooves 503 are evenly opened on the outer surface of the hollow tube 502, and inflatable bags 504 are adhered to the inner surfaces of the plurality of grooves 503, an inner frame 508 is symmetrically fixedly connected to the inner surface of the hollow tube 502, an air pipe 509 is fixedly connected between the inner surfaces of the two inner frames 508, a plurality of connecting pipes 510 are evenly fixedly connected to the outer surface of the air pipe 509, a second side frame 505 is fixedly connected to the end surface of the other side of the hollow tube 502, and the winding tube 507 is located at the outer side of the plurality of inflatable bags 504.

[0024] Reference Figure 2 and Figure 3 The connecting tube 510 passes through the hollow tube 502 and is fixedly connected to the inflatable bag 504. The inflatable bag 504 and the trachea 509 are connected. The connecting tube 510 is set so that the inflatable bag 504 and the trachea 509 are in a connected state. The inflation and deflation of the inflatable bag 504 can be controlled by inflating and deflation at the trachea 509.

[0025] Reference Figure 2 and Figure 3The end face of the air pipe 509 is fixedly connected with a first connecting pipe 511, and the end face of the first connecting pipe 511 is fixedly connected with an air pump 512. The air pump 512 is fixedly connected to the second side frame 505. When the winding tube 507 is sleeved on the outer side of the hollow tube 502 for winding, the air pump 512 is started to inflate air into the air pipe 509 through the connection of the first connecting pipe 511. The air bag 504 will expand after being inflated. The inflated air bag 504 can make the winding tube 507 tightly sleeved on the outer side of the hollow tube 502 for use.

[0026] Reference Figure 2 and Figure 3 The other end face of the air pipe 509 is fixedly connected with a second connecting pipe 513, and the end face of the second connecting pipe 513 is fixedly connected with an air pump 514. The air pump 514 is fixedly connected to the first side frame 501. When the winding tube 507 needs to be removed after the winding is completed, the air pump 514 is started to exhaust air from the air pipe 509 through the connection of the second connecting pipe 513. After the air is exhausted, the inflatable bag 504 will return to a deflated state, so that the inner side of the winding tube 507 loses support, and the winding tube 507 can be easily removed for further winding.

[0027] Reference Figure 2 and Figure 3 The outer surface of the second side frame 505 is fixedly connected with a support shaft 506, and the top of the bottom plate 1 is fixedly connected with an electric push rod 6. When winding, starting the electric push rod 6 can drive the support seat 7 to move upward to provide support for the support shaft 506.

[0028] Reference Figure 4 The upper end surface of the electric push rod 6 is fixedly connected to a support seat 7, and a plurality of circular grooves are evenly arranged on the inner surface of the support seat 7. Balls 8 are arranged on the inner surfaces of the plurality of circular grooves. The outer surface of the support shaft 506 is in contact with the inner surface of the support seat 7. The support seat 7 is used to provide support for the support shaft 506, so that the stability of the hollow tube 502 during rotation and winding can be improved. The arrangement of the ball 8 can reduce the friction force, thereby reducing the wear of the device.

[0029] The implementation principle of the winding structure of a film blowing machine in the embodiment of the present application is as follows: when the film blowing machine is used to wind the plastic film, the winding tube 507 is sleeved on the outer side of the hollow tube 502. At this time, the inflatable bag 504 is in an uninflated state, and the diameter of the winding tube 507 is slightly larger than the diameter of the hollow tube 502, so the winding tube 507 can be easily sleeved on the outer side of the hollow tube 502, and the air pump 512 is started to inflate air into the air pipe 509 through the connection of the first connecting pipe 511. After the inflatable bag 504 is inflated, it will expand. The inflated inflatable bag 504 can make the winding tube 507 tightly sleeved on the outer side of the hollow tube 502 for use, and then the motor 3 is started. After the motor 3 is started, it drives the first side frame 501 to rotate through the connection of the rotating shaft 4, thereby driving The hollow tube 502 rotates to wind the plastic film. While winding, the electric push rod 6 is started to extend and drive the support seat 7 to move upward. After the support seat 7 moves up and fits into the support shaft 506, the stability of the hollow tube 502 during rotation and winding can be improved. After the whole roll of plastic film is wound, the winding tube 507 needs to be removed together with the rolled plastic film. At this time, the vacuum pump 514 is started. The vacuum pump 514 and the air pump 512 both use miniature wireless air pumps, which are battery-powered and can be charged by plugging in a wire. They will not affect the operation of the hollow tube 502. After the air is pumped out, the inflatable bag 504 will return to a deflated state, causing the inner side of the winding tube 507 to lose support. The winding tube 507 can be easily removed for continued winding, which is convenient for placing and removing the winding tube 507.
