An annular block is fixedly installed on the inner wall of the hopper, and the screening net is arranged on the annular block. The circular film blowing machine hopper is convenient for screening and feeding plastic particles, preventing the uneven size of plastic particles from causing insufficient heating and resulting in poor film blowing quality. It is also convenient for spirally extruding plastic particles to feed, avoiding the phenomenon of accumulation and blockage in the hopper caused by too fast feeding of plastic particles, thereby effectively improving the feeding efficiency and practicality of the hopper, and facilitating the shaking of the screening net up and down to prevent the accumulation of plastic particles in the hopper, thereby improving the practicality of the hopper.

[0004] However, in the above method, the film blowing machine and the hopper are integrated. When the hopper is damaged, it is not convenient to disassemble and install the hopper, which causes inconvenience in replacing and repairing the hopper. Summary of the invention

[0019] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0020] Please refer to Figures 1 to 4 , Figure 1 which is a schematic diagram of the overall structure of a hopper of a blown film machine of the present utility model, Figure 2 which is a schematic diagram of the overall structure of another angle of a hopper of a blown film machine of the present utility model, Figure 3 which is a front view of the overall structure of a hopper of a blown film machine of the present utility model, Figure 4 which is a sectional view of the overall structure of a hopper of a blown film machine of the present utility model.

[0021] A hopper of a blown film machine of the present utility model includes a hopper body 101 and a disassembly and assembly component 102. The disassembly and assembly component 102 includes a plug board 103, a mounting seat 104, a screw rod 105, a top plate 106, a crank 107, a separation mechanism 108, a fixed ring 109 and a positioning part 110. The separation mechanism 108 includes a mounting frame 111, a motor 112, a transmission rod 113, a spiral blade 114, a guide plate 115, a screening mesh 116, a slide bar 117, an electric push rod 118 and a stabilizing frame 119. Through the foregoing solution, the problem that when the existing circular hopper of a blown film machine is damaged, it is not convenient to disassemble and install the hopper, resulting in inconvenience in replacing and repairing the hopper is solved.

[0022] For this specific implementation manner, the plastic film raw material is put into the hopper body 101 and made to enter the blown film machine along the hopper body 101, which is convenient for subsequent processing. The usage method and specific structure of the hopper body 101 are described in detail in the patent with the publication number CN217777478U, which is not the protection scope of this application and will not be elaborated here.

[0023] Among them, the plug board 103 is fixedly connected to the hopper body 101 and is located at the bottom of the hopper body 101. The mounting seat 104 is slidably connected to the plug board 103 and is located on the side of the plug board 103. The screw rod 105 is threadedly connected to the mounting seat 104 and is located on one side of the mounting seat 104. The top plate 106 is rotatably connected to the screw rod 105, is slidably connected to the mounting seat 104, and is located on one side of the screw rod 105. The crank 107 is fixedly connected to the screw rod 105 and is located on the side of the crank 107 away from the top plate 106. The separation mechanism 108 is arranged on one side of the hopper body 101. When producing plastic film, it is necessary to put the plastic film raw material along the hopper so that it enters the blown film machine. First, start the separation mechanism 108 and put the plastic film raw material into the hopper body 101. After the raw material enters the hopper body 101, through the operation of the separation mechanism 108, the sundries in the plastic film raw material are separated, and other raw materials pass through the hopper body 101 and enter the blown film machine to start subsequent processing. When it is necessary to replace the hopper body 101 of different sizes according to the use requirements, the staff can hold the crank 107 and drive the screw rod 105 to rotate, so that the screw rod 105 rotates on the mounting seat 104, driving the top plate 106 to retract, so that the top plate 106 no longer presses against the plug board 103 on the mounting seat 104. At this time, the staff can slide the plug board 103 out of the mounting seat 104, and the hopper body 101 moves accordingly and is no longer fixed on the blown film machine, thereby facilitating the staff to replace the hopper body 101. After the replacement is completed, align the slide plate at the bottom of the hopper body 101 with the mounting seat 104 on the blown film machine and slide it into the mounting seat 104. At this time, the staff holds the crank 107 and drives the screw rod 105 to rotate, pushing the top plate 106 to move in the mounting seat 104 so that it presses against the plug board 103, thereby fixing the position of the plug board 103 in cooperation with the mounting seat 104, and the position of the hopper body 101 is fixed accordingly, thus solving the problem that it is inconvenient to disassemble and install the hopper of the existing circular blown film machine when the hopper is damaged, resulting in inconvenience in replacing and repairing the hopper.

[0024] Secondly, the fixed ring 109 is fixedly connected to the mounting seat 104, rotatably connected to the screw rod 105, and located on one side of the mounting seat 104. The positioning member 110 is threadedly connected to the fixed ring 109 and located on the side of the fixed ring 109. When the staff holds the crank 107 to drive the screw rod 105 to rotate and push the top plate 106 against the plug board 103, the positioning member 110 on the fixed ring 109 can be rotated clockwise. The positioning member 110 passes through the fixed ring 109 and abuts against the screw rod 105, so that the screw rod 105 stops rotating.

[0025] Thirdly, the mounting bracket 111 is fixedly connected to the hopper body 101 and located on one side of the hopper body 101. The motor 112 is fixedly connected to the mounting bracket 111 and located on the top of the mounting bracket 111. The transmission rod 113 is fixedly connected to the output end of the motor 112 and located on one side of the motor 112. The spiral blade 114 is fixedly connected to the transmission rod 113 and located on one side of the transmission rod 113. When the plastic film raw material enters the hopper body 101, the motor 112 on the mounting bracket 111 is started. The output end of the motor 112 drives the transmission rod 113 to rotate, so that the spiral blade 114 rotates accordingly, which can push the plastic film raw material in the hopper body 101, stir it, and enable it to flow in the hopper body 101.

[0026] In addition, the guide plate 115 is fixedly connected to the hopper body 101 and located at the bottom of the hopper body 101. The screening mesh 116 is slidably connected to the guide plate 115 and located at the bottom of the guide plate 115. The sliding rod 117 is fixedly connected to the guide plate 115, slidably connected to the screening mesh 116, and located on one side of the screening mesh 116. The electric push rod 118 is fixedly connected to the guide plate 115, and the output end of the electric push rod 118 is fixedly connected to the screening mesh 116 and located on one side of the screening mesh 116. The guide plate 115 provided at the bottom of the hopper body 101 can prevent the plastic film raw material from falling to the edge corners of the hopper body 101. When the spiral blade 114 rotates, the electric push rod 118 can be started. The output end of the electric push rod 118 pushes the screening mesh 116 to move on the sliding rod 117, cooperating with the rotation of the spiral blade 114, to prevent the plastic film raw material from being blocked in the hopper body 101.

[0027] Meanwhile, the separation mechanism 108 further includes a stabilizing frame 119. The stabilizing frame 119 is fixedly connected to the insertion plate 103, rotatably connected to the transmission rod 113, and is located at the bottom of the transmission rod 113. When the transmission rod 113 rotates, the stabilizing frame 119 provided at its bottom can prevent the transmission rod 113 from shifting during rotation, making its rotation more stable.

[0028] For a hopper of a blown film machine of the present utility model, when producing a plastic film, start the motor 112 on the mounting frame 111. The output end of the motor 112 drives the transmission rod 113 to rotate, causing the spiral blade 114 to rotate accordingly, which can push the plastic film raw material in the hopper body 101 and agitate it, enabling it to flow in the hopper body 101. The screening mesh 117 can screen the plastic film raw material to prevent impurities from entering the blown film machine. Meanwhile, the electric push rod 118 can be started. The output end of the electric push rod 118 pushes the screening mesh 116 to move on the sliding rod 117, cooperating with the rotation of the spiral blade 114 to prevent the plastic film raw material from clogging in the hopper body 101, thereby effectively improving the feeding efficiency and practicality of the hopper body 101. On the other hand, it is convenient to drive the screening mesh 117 to vibrate up and down, further preventing the phenomenon of plastic film raw material accumulating in the hopper body 101, and significantly improving the practicality of the hopper. When it is necessary to replace the hopper body 101 of different sizes according to usage needs, the staff can hold the crank 107 and drive the screw rod 105 to rotate, causing the screw rod 105 to rotate on the mounting seat 104, driving the top plate 106 to retract, so that the top plate 106 no longer presses against the insertion plate 103 on the mounting seat 104. At this time, the staff can slide the insertion plate 103 out of the mounting seat 104, and the hopper body 101 moves accordingly and is no longer fixed to the blown film machine, thus facilitating the staff to replace the hopper body 101. After the replacement is completed, align the sliding plate at the bottom of the hopper body 101 with the mounting seat 104 on the blown film machine and slide it into the mounting seat 104. At this time, the staff holds the crank 107 and drives the screw rod 105 to rotate, pushing the top plate 106 to move in the mounting seat 104 so that it presses against the insertion plate 103, thereby fixing the position of the insertion plate 103 in cooperation with the mounting seat 104, and the position of the hopper body 101 is fixed accordingly, thus solving the problem that when the existing circular hopper of the blown film machine is damaged, it is inconvenient to disassemble and install the hopper, resulting in inconvenience in replacing and repairing the hopper.
