Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an automatic recovery device for polyethylene plastic film rim charge comprises a slitting roller 1, slitting blades 2, a frame 3, a connecting pipe 4 and a recovery box 5, wherein two ends of the slitting roller 1 penetrate through the wall body of the frame 3 and are movably connected with the wall body of the frame 3 through rolling bearings, through holes 11 are formed in the wall bodies at two ends of the slitting roller 1, the slitting blades 2 are fixed on the frame 3 through bolts, the connecting pipe 4 is connected with the top end of the recovery box 5 through a flange seal, a cross bar 8 is welded and connected with the inner wall of the connecting pipe 4, an exhaust fan 6 is fixed on the top end of the recovery box 5 through a bolt, the exhaust end of the exhaust fan 6 penetrates through the wall body at the top end of the recovery box 5 and is welded and connected with the wall body at the top end of the recovery box 5, a mesh enclosure 7 is welded and connected with the inner wall of the recovery box 5 on the periphery of the exhaust end of the exhaust fan 6, and the horizontal pole 8 that is located dividing and cutting roller 1 inside passes through connecting rod 9 and baffle 10 welded connection, welded connection has sawtooth piece 12 on the intercommunication department of through-hole 11 and dividing and cutting roller 1 inner wall, and sawtooth piece 12 uses through-hole 11 central point to be circular and be the annular array distribution, during the operation, with air exhauster 6 access external power supply, air exhauster 6 begins to receive gas to dividing and cutting roller 1 through connecting pipe 4, and then produce suction in through-hole 11 department, divide and cut roller 1 and carry the film and carry out the segmentation, divide and cut blade 2 can divide the film to carry out the segmentation, the rim charge that is downcut is adsorbed by through-hole 11 department production suction, and be sucked inside dividing and cutting roller 1 gradually, in-process once more, can be cut up by sawtooth piece 12, the rim charge after cutting up can be sucked to recycle in collection box 5.

Divide and cut roller 1 to be hollow structure, and the one end of cutting roller 1 extend to connecting pipe 4 inside and with connecting pipe 4 inner walls between be antifriction bearing swing joint, and this one end of dividing and cutting roller 1 is the opening form, the rim charge that gets into in dividing and cutting roller 1 like this can enter into to retrieve in the collection box 5 through connecting pipe 4, be seal structure between roller 1 and the connecting pipe 4 is cut to the while, make air exhauster 6 can produce stronger suction in through-hole 11 departments, can inhale the rim charge fast and tear the bits of broken glass.

The mesh enclosure 7 is of a hemispherical structure, the mesh enclosure 7 is of a porous structure, and the inner diameter of holes in the mesh enclosure 7 is 2-5mm, so that when the exhaust fan 6 exhausts air, the mesh enclosure 7 can block off rim charge in the recovery box 5, and the rim charge is prevented from being sucked into the exhaust fan 6 to damage the exhaust fan 6.

Baffle 10 is circular-arcly, and the external diameter of baffle 10 is unanimous with 1 internal diameter of roller of cutting, and the outer wall of baffle 10 with set up the 1 inner wall laminating of roller of cutting of through-hole 11, baffle 10 can shelter from the through-hole 11 of 1 upper part of roller of cutting, the film that can avoid not carrying on the segmentation like this receives the influence of through-hole 11 suction, the segmentation work of having guaranteed the film can not receive the interference, baffle 10 is along with the rotation of roller 1 of cutting, under the effect support of horizontal pole 8 and connecting rod 9, be in fixed state all the time, can shelter from the through-hole 11 of 1 upper part of roller of cutting all the time, the sound construction, the operation is stable.

Through-hole 11 wholly is round platform shape structure, and through-hole 11 with cut 1 outer wall's of roller intercommunication department aperture be greater than with cut 1 inner wall's of roller intercommunication department aperture, like this the film when being inhaled to through-hole 11 in, because the inboard aperture of through-hole 11 is less, like this the film when being entered into, can contact with sawtooth piece 12, and then cut up by sawtooth piece 12, the rim charge after being cut up can be by the suction to the collection box 5 in.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
