[0011] The specific content of the utility model will be described in detail below in combination with the drawings and examples.
[0012] As Figure 1 and Figure 2 The utility model provides a material feeding structure for blowing film machine, including material frame 1, one side of material frame 1 is fixed with connecting frame 2, be equipped with with connecting frame 2 is connected in material frame 1 and is equipped with magnet 4, be equipped with sleeve 5 in connecting frame 2 one end penetrates both sides of material frame 1 and is covered on magnet 4, sleeve 5 can move towards the side of material frame 1 away from connecting frame 2. Material frame 1 is connected with the top of blowing film machine, when plastic particle enters material frame 1 and contacts magnet 4, the iron filings or iron sheet in plastic particle is adsorbed on sleeve 5, and the filtration of the iron filings or iron sheet in plastic particle is completed.
[0013] As Figure 1 The side of material frame 1 away from connecting frame 2 is fixed with fixed frame 3, and the screw rod 6 is rotatably connected in fixed frame 3, and the motor 61 for driving the screw rod 6 is arranged on the fixed frame 3, and the moving plate 62 threadedly connected with the screw rod 6 is fixed on the sleeve 5. The main body of the motor 61 is fixed on one side in the fixed frame 3, the rotating shaft of the motor 61 is fixed with one end of the screw rod 6, and the motor 61 adopts a servo motor; after starting the motor 61 and making the screw rod 6 rotate, the moving plate 62 can drive the sleeve 5 to move horizontally, so that the sleeve 5 moves towards the fixed frame 3, and the iron filings or iron sheet adsorbed on the sleeve 5 enters the fixed frame 3 along with the sleeve 5, the magnet 4 does not generate magnetic force on the iron filings or iron sheet, and the iron sheet or iron filings automatically falls down, so that the automatic cleaning of the iron filings or iron sheet on the sleeve 5 is completed; the part of the sleeve 5 in the connecting frame 2 enters the material frame 1, and the iron filings or iron sheet continues to be adsorbed on the sleeve 5 by the magnet 4; the subsequent horizontal repeated movement of the sleeve 5 can make the iron filings or iron sheet on the sleeve 5 automatically fall into the connecting frame 2 or the fixed frame 3, so that manual cleaning of the iron filings or iron sheet on the sleeve 5 is not needed, and the influence of the iron sheet or iron filings on the sleeve 5 on the adsorption force of the magnet 4 on the iron filings or iron sheet in the subsequent plastic particles is avoided, so that the magnet 4 can effectively adsorb the iron filings or iron sheet.
[0014] As Figure 1 and Figure 2As shown, the connecting frame 2 is fixed with a crossbar 41 connected with the end of the magnet 4, and the crossbar 41 is located inside the sleeve 5. The crossbar 41 can fix the magnet 4, so that the magnet 4 is located in the material frame 1, and the two ends of the magnet 4 are flush with the two sides of the material frame 1, respectively.
[0015] As shown in Figure 1 and Figure 2 , the two sides of the material frame 1 are provided with a circular hole 8, and the inner diameter of the circular hole 8 increases from the inside of the material frame 1 to the outside of the material frame 1. When the sleeve 5 moves, the iron filings or iron sheets on the sleeve 5 pass through the circular hole 8 and then automatically fall downward. The setting that the inner diameter of the circular hole 8 increases from the inside of the material frame 1 to the outside of the material frame 1 can effectively prevent the iron filings or iron sheets from accumulating in the circular hole 8, and the iron filings or iron sheets falling into the circular hole 8 can effectively slide into the connecting frame 2 or the fixed frame 3.
[0016] As shown in Figure 1 and Figure 2 , the magnet 4 is provided with two groups, and the two groups of magnets 4 are staggered in an up-down distribution; the moving plate 62 is fixed with the two groups of sleeves 5. The setting of the two groups of magnets 4 can effectively disperse the plastic particles when they fall downward, so that the iron filings or iron sheets in the plastic particles can be better adsorbed on the sleeve 5 by the magnet 4.
[0017] As shown in Figure 1 and Figure 2 , the two sides in the material frame 1 are fixed with inclined guide plates 7. The setting of the guide plates 7 can prevent the plastic particles from falling toward the two sides of the material frame 1, and avoid the possibility that the plastic particles enter the circular hole 8.
[0018] As shown in Figure 1 and Figure 2 , the connecting frame 2 and the fixed frame 3 are both fixed with two cleaning plates 9, and a group of perforations are formed on the cleaning plate 9, and the outer wall of the sleeve 5 is in contact with the inner wall of the perforation. The setting of the cleaning plate 9 can scrape off the impurities adhered to the surface of the sleeve 5 when the sleeve 5 moves, so as to avoid that the impurities cannot fall off by adhering to the sleeve 5.
[0019] As shown in Figure 1 , the bottom of the connecting frame 2 and the fixed frame 3 is inclined, and the connecting frame 2 and the fixed frame 3 are both communicated with a discharge pipe. The inclined setting of the bottom of the connecting frame 2 and the fixed frame 3 can effectively make the iron filings or iron sheets discharged through the discharge pipe; and the bottom of the connecting frame 2 and the fixed frame 3 is fixed with a support rod connected with the film blowing machine, which can increase the firmness of the connecting frame 2 and the fixed frame 3.
[0020] In use, when the plastic particles enter the frame 1 and contact the sleeve 5, the iron filings and iron pieces in the plastic particles are adsorbed on the sleeve 5 by the magnet 4, and the filtering of the iron filings or iron pieces is completed; when the iron filings or iron pieces on the sleeve 5 accumulate more, the motor 61 drives the screw rod 6 to rotate, and the moving plate 62 drives the sleeve 5 to move horizontally (firstly moves to the right into the fixed frame 3, and the position is shown in the middle), and then the part of the sleeve 5 in the frame 1 enters the fixed frame 3, and the iron filings or iron pieces on the sleeve 5 automatically fall downward into the fixed frame 3, and the part of the sleeve 5 in the connecting frame 2 enters the frame 1, and the manual cleaning of the iron filings or iron pieces on the sleeve 5 is not needed when the machine is stopped; and subsequently, the sleeve 5 can be restored, and the part of the sleeve 5 in the frame 1 enters the connecting frame 2, so that the iron filings or iron pieces on the sleeve 5 fall downward into the connecting frame 2.
