DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0028] Reference Figures 1-5The utility model provides an electromagnetic thermal cycle paper plastic separating machine, including frame 1, be provided with transmission mechanism 2 for transmission paper plastic composite bag in frame 1, the both sides of transmission mechanism 2 are connected with ventilation pipe 5, transmission mechanism 2 is provided with fan 3, be provided with electromagnetic heat pipe 4 between fan 3 and ventilation pipe 5, electromagnetic heat pipe 4 is the existing pipe outer wall winding electromagnetic coil, do not make too much repetition here, when using, operating personnel heat the air in pipe through electromagnetic heat pipe 4, then utilize fan 3 and deliver heat to transmission mechanism 2, paper plastic composite bag enters transmission mechanism 2 and is transmitted, and paper plastic composite bag is in the heat environment of fan 3 delivery in the transmission process, and then high heat environment makes the plastic part of paper plastic composite bag change plastic and shrink, gradually and paper quality part separate, to realize the effect of paper plastic separation, finally through transmission mechanism 2 and deliver paper plastic composite bag of completing paper plastic separation out separating machine and collect, namely complete paper plastic separation of paper plastic composite bag.

[0029] In some embodiments, the transmission mechanism 2 is provided with a return air pipe 7 connected with the fan 3, which can recycle the heat in the housing 21 and deliver the waste heat to the electromagnetic heat pipe 4 for secondary utilization, saving cost and improving resource utilization.

[0030] In some embodiments, the transmission mechanism 2 is provided with a cutting mechanism 6 inside for cutting the paper plastic composite bag. Before the paper plastic composite bag is placed into the transmission mechanism 2 by the operator, it is first placed onto the cutting mechanism 6 for cutting. After the cutting mechanism 6 cuts the paper plastic composite bag on both sides, it is then delivered onto the transmission mechanism 2 for paper plastic separation operation. This can cut the paper plastic composite bag, which not only increases the heating area of the paper plastic composite bag and improves the paper plastic separation rate, but also reduces the human resources for cutting the paper plastic composite bag and saves labor cost.

[0031] In some embodiments, the transmission mechanism 2 includes a housing 21 provided with a conveyor belt 22 inside. A stop block 23 is welded above the end of the conveyor belt 22 in the housing 21. A compression roller 24 is arranged on the side of the housing 21 opposite the stop block 23. When in use, the operator places the paper plastic composite bag into the cutting mechanism 6. After the cutting mechanism 6 cuts the paper plastic composite bag, the conveyor belt 22 is used to deliver the paper plastic composite bag. During the delivery process, the compression roller 24 is used to flatten the paper plastic composite bag to avoid the paper plastic composite bag from being raised during paper plastic separation, which affects the paper plastic separation effect of other paper plastic composite bags. The stop block 23 can prevent heat from escaping and speed up the paper plastic separation efficiency. The conveyor belt 22 is provided with a mesh chain, which can quickly absorb heat, increase the contact area of the paper plastic composite bag with heat, and improve the paper plastic separation efficiency of the paper plastic composite bag.

[0032] In some embodiments, the baffle 23 is rotationally connected with a heat insulation band 25. The heat insulation band 25 not only can prevent heat loss in the shell 21, improve the paper-plastic separation rate of the paper-plastic composite bag, but also can shield the paper-plastic composite bag when the support 62 drives the paper-plastic composite bag to rotate and move towards the cutter 65 after the operator fixes the paper-plastic composite bag on the support 62. As the support 62 drives the paper-plastic composite bag to gradually move towards the cutter 65, the heat insulation band 25 slowly slides from the paper-plastic composite bag, thereby forming a pushing action on the paper-plastic composite bag, pushing the paper-plastic composite bag to be more firmly fixed on the support 62, and avoiding the paper-plastic composite bag from falling off the support 62 due to unstable fixation when the support 62 drives the paper-plastic composite bag to rotate.

[0033] As Figure 3In some embodiments, the cutting mechanism 6 comprises a ring-shaped guide rail 61, a support 62 is slidingly connected to the ring-shaped guide rail 61, the ring-shaped guide rail 61 is an existing electric sliding rail, which is not described in detail here, the support 62 is provided with a flat gear 63, the stop block 23 of the conveying mechanism 2 is embedded with a rack 64, the rack 64 is matched with the flat gear 63, the rack 64 is provided with two, which are embedded on both sides of the stop block 23 located in the middle of the shell 21, the bottom of the stop block 23 of the conveying mechanism 2 is provided with a cutter 65 installed on the side of the rack 64, the cutter 65 is provided with two, in use, the operator fixes the open end of the paper-plastic composite bag on the support 62, at this time the support 62 faces the operator, then the support 62 is controlled to move by the ring-shaped guide rail 61, when the support 62 moves to the position of the rack 64 of the conveying mechanism 2, the flat gear 63 on the support 62 is engaged with one rack 64, so that the flat gear 63 drives the support 62 to rotate, at this time the support 62 faces the cutter 65, then the support 62 drives the paper-plastic composite bag to rotate to move towards the cutter 65, in the process of moving, the two sides of the paper-plastic composite bag are cut open by the two cutters 65, then the support 62 is driven to continue to move by the ring-shaped guide rail 61, in the process of moving, the cut open paper-plastic composite bag is blown off from the support 62 to the conveyor belt 22 by the hot air conveyed in the ventilation pipe 5, at the same time, the cut open paper-plastic composite bag is heated by the hot air conveyed in the ventilation pipe 5, so that it is quickly heated to be pre-separated, at this time the orientation of the support 62 is parallel to the moving track, then the paper-plastic separated bag dropped on the conveyor belt 22 is flattened by the compression roller 24, then the paper-plastic separated bag is conveyed out of the shell 21 by the conveyor belt 22 after completing the paper-plastic separation, finally the support 62 moves on the ring-shaped guide rail 61, in the process of moving, the flat gear 63 on the support 62 is engaged with the other rack 64, so that the support 62 rotates, until the orientation of the support 62 is perpendicular to the moving track, finally the support 62 is controlled to move to the initial position by the ring-shaped guide rail 61 to fix the next paper-plastic composite bag: the support 62 can be provided with multiple, the multiple supports 62 are cyclically moved, that is, the paper-plastic separation of batch paper-plastic composite bags is completed.

[0034] In some embodiments, the support 62 comprises a movable slide rod 621, the end of the movable slide rod 621 is provided with a pneumatic cylinder 622, two moving blocks 623 are arranged on the pneumatic cylinder 622, and one supporting rod 624 is arranged on the opposite side of each moving block 623; when the movable slide rod 621 moves on the annular guide rail 61 and moves to the inlet of the conveying mechanism 2, the operator puts the open end of the paper-plastic composite bag on the supporting rod 624, and then the pneumatic cylinder 622 controls the two moving blocks 623 to move in opposite directions, so that the supporting rod 624 moves inside the paper-plastic composite bag and expands the paper-plastic composite bag to be fixed, avoiding the paper-plastic composite bag from falling off; the pneumatic cylinder 622 is a conventional transverse pneumatic cylinder, and the moving blocks 623 can be controlled to move left and right, which will not be described in detail here; then the supporting rod 624 with the paper-plastic composite bag moves to the cutting knife 65 for cutting; after the two sides of the paper-plastic composite bag are cut by the cutting knife 65, the pneumatic cylinder 622 controls the two moving blocks 623 to reset, until the movable slide rod 621 moves to the inlet of the conveying mechanism 2 again, the paper-plastic composite bag is put on the supporting rod 624 by the operator, and the above process is repeated, so as to fix the paper-plastic composite bag.

[0035] In some embodiments, the middle part of the supporting rod 624 is provided with a gap, and the gap is beyond the range of the two sides of the pneumatic cylinder 622 when the distance between the two supporting rods 624 is the farthest; when the support 62 with the paper-plastic composite bag moves to the cutting knife 65 and is cut by the cutting knife 65, the cutting path of the cutting knife 65 is in the gap of the supporting rod 624, which can avoid the collision between the cutting knife 65 and the edge of the pneumatic cylinder 622 when cutting the paper-plastic composite bag, so that the pneumatic cylinder 622 is damaged by the cutting knife 65, which affects the cutting of the next batch of paper-plastic composite bags, thereby weakening the separation effect of the paper-plastic composite bag.

[0036] In some embodiments, the outer surfaces of the electromagnetic heat pipe 4 and the ventilation pipe 5 are both wrapped with sealing belts, which can not only seal the electromagnetic heat pipe 4 and accelerate the formation of heat, but also ensure that the heat in the electromagnetic heat pipe 4 and the ventilation pipe 5 will not escape when the fan 3 sends the air heated by the electromagnetic heat pipe 4 into the ventilation pipe 5, thereby improving the paper-plastic separation rate and ensuring the paper-plastic separation effect.

[0037] In summary, the electromagnetic heat pipe 4 is used to heat the air, and the fan 3 is used to send the heat to the shell 21 to heat the paper-plastic composite bag, so that the plastic part of the paper-plastic composite bag shrinks and separates from the paper part when heated, thereby realizing paper-plastic separation, changing the previous use of a lamp tube for heating, reducing maintenance costs, and ensuring the paper-plastic separation effect. The heat is stable and uniform, and the cutting mechanism 6 is used to cut the paper-plastic composite bag, which eliminates the need for manual pre-cutting before paper-plastic separation, reduces labor costs, improves the degree of automation of paper-plastic separation, realizes automatic paper-plastic separation of batches of paper-plastic composite bags, is convenient and fast, improves the paper-plastic separation rate, and increases the yield of the completed paper-plastic composite bags.

[0040] b. Then the support 62 drives the paper-plastic composite bag to move on the annular guide rail 61, and after the paper-plastic composite bag is cut by the cutter 65 during the movement, it falls on the conveying belt 22 to separate the paper and plastic;

[0041] c. When the operator puts the paper-plastic composite bag on the support rod 624, the operator controls the fan 3 to deliver the heat of the electromagnetic heat pipe 4 into the shell 21, and uses the heat of the hot air to make the plastic part of the paper-plastic composite bag shrink and separate from the paper part, thereby completing the paper-plastic separation;

[0042] d. Finally, the paper-plastic composite bag after the paper-plastic separation is delivered out of the shell 21 by the conveying belt 22 to be collected.
