[0033] Example 1

[0034] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a film blowing machine that is convenient for adjusting the width of a plastic film, and the structure includes:

[0035] The operating table 100 has a base 101 fixedly mounted on the bottom of the operating table 100. The base 101 supports the operating table 100. When the plastic factor enters the operating table 100, it can be heated.

[0036] The heating unit 200 includes a heating wire 201, a transmission tube 202 and a servo motor 203. The heating wire 201 is fixedly installed on one side of the inner wall of the operating table 100. The transmission tube 202 is fixedly connected to one end of the operating table 100. The servo motor 203 is fixedly installed on the other end of the operating table 100. The output end of the servo motor 203 is drivingly connected to a first rotating rod 204. During use, plastic particles enter the operating table 100 through the unloading component 300, and the servo motor 203 is started to drive the first rotating rod 204 to rotate. The first rotating rod 204 drives the stirring blade 2041 to stir the plastic particles, which are heated by the heating wire 201 to form a molten liquid. The molten plastic liquid is transported to the film blowing box 405 through the transmission tube 202.

[0037] The material discharging assembly 300 includes a material discharging hopper 301 and a buffer port 302. The material discharging hopper 301 is fixed on the buffer port 302, and the buffer port 302 is fixed on the operating table 100. The inner wall of the buffer port 302 is rotatably connected to a second rotating rod 303, and the surface of the second rotating rod 303 is rotatably connected to a baffle 304. During use, plastic particles are poured into the material discharging hopper 301, and the plastic particles are accumulated on the baffle 304 in the buffer port 302. The belt 2043 drives the roller 2042 to rotate. The first rotating rod 204 and the sector gear 3034 rotate synchronously. When the sector gear 3034 rotates to the meshing position between the teeth and the driving gear 3033, the second rotating rod 303 is driven to rotate. At this time, the baffle 304 flips over, and the plastic particles in the buffer port 302 fall down. When the teeth are not meshed with the driving gear 3033, the spring 3032 drives the adjustment block 3031 to return to the normal position, so that the baffle 304 blocks the buffer port 302 as the second rotating rod 303 rotates, thereby realizing multiple buffering and unloading.

[0038] The film blowing unit 400 includes a fixed platform 401, on which an air pump 402 is installed. An air pipe 403 is provided at the output end of the air pump 402, on which a circular air duct regulating valve 404 is provided. A film blowing box 405 is fixed at one end of the air pipe 403. During use, the air pump 402 is started to output gas to the film blowing box 405 through the air pipe 403, and the film is output through the film blowing head 4051. The circular air duct regulating valve 404 is adjusted to control the flow rate of air delivered by the air pipe 403, thereby adjusting the film width.

[0039] Furthermore, a stirring blade 2041 is fixed to the surface of the first rotating rod 204, one end of the first rotating rod 204 is rotatably connected to a roller 2042, and the surface of the roller 2042 is rotatably connected to a belt 2043. The belt 2043 drives the two rollers 2042 to rotate, so that the first rotating rod 204 and the second rotating rod 303 can rotate at the same time. The first rotating rod 204 drives the stirring blade 2041 to rotate to stir the plastic factor.

[0040] Furthermore, the surface of the second rotating rod 303 is also rotatably connected to an adjustment block 3031, and the surface of the adjustment block 3031 is fixedly connected to a spring 3032. The adjustment block 3031 is driven to rotate by the second rotating rod 303, and when it does not rotate, the adjustment block 3031 is driven to return to the normal position by the elastic properties of the spring 3032 itself.

[0041] Furthermore, one end of the second rotating rod 303 is rotatably connected to a driving gear 3033, and a fan gear 3034 is meshed on the surface of the driving gear 3033. The fan gear 3034 is rotatably connected to one side of the roller 2042. The driving gear 3033 is driven to rotate by the toothed part of the fan gear 3034, thereby realizing the reciprocating flipping of the baffle 304.

[0042] Furthermore, a tripod 4011 is fixedly connected to the bottom of the fixed platform 401, and the number of the tripods 4011 is four. The fixed platform 401 is supported by the tripods 4011, which increases the stability of the device.

[0043] Furthermore, one side of the film blowing box 405 is fixedly connected to one end of the transmission pipe 202, and a film blowing head 4051 is provided on the film blowing box 405, through which the film can be output, and then the film can be rolled up by the rolling mechanism.

[0044] During use, first, plastic particles are poured into the lower hopper 301, and the plastic particles are accumulated on the baffle 304 in the buffer port 302. The servo motor 203 is started to drive the first rotating rod 204 to rotate, and the first rotating rod 204 drives the stirring blade 2041 to stir the plastic particles, which are heated by the electric heating wire 201 to form a molten liquid, and the molten plastic liquid is transported to the film blowing box 405 through the transmission pipe 202;

[0045] Then, the belt 2043 drives the roller 2042 to rotate, so that the first rotating rod 204 and the fan gear 3034 rotate synchronously. When the fan gear 3034 rotates to the meshing position between the teeth and the driving gear 3033, it drives the second rotating rod 303 to rotate. At this time, the baffle 304 flips over, and the plastic particles in the buffer port 302 fall down. When the teeth are not meshed with the driving gear 3033, the spring 3032 drives the adjustment block 3031 to return to the normal position, so that the baffle 304 blocks the buffer port 302 with the rotation of the second rotating rod 303, thereby realizing multiple buffering and unloading.

[0046] Finally, the air pump 402 is started to output gas to the film blowing box 405 through the air pipe 403, and the film is output through the film blowing head 4051. The air flow rate delivered by the air pipe 403 is controlled by adjusting the circular air duct regulating valve 404, so as to adjust the film width.

[0047] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
