Technical Field

The invention relates to the technical field of garbage bag processing, in particular to a rolling machine for garbage bag processing and a rolling method thereof.

Background technique

During the processing and production of garbage bags, plastic particles need to be made into plastic film. This operation is usually carried out in a blow molding machine. The plastic particle raw materials are poured into the blow molding machine and melted at high temperature.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1-3 and 5-6. The present invention provides a technical solution: a rolling machine for processing garbage bags, comprising a protective shell 1, a roller placing frame 2 is arranged on one side of the protective shell 1, a group of rollers 5 are placed in the roller placing frame 2, and a ring array of air inlet holes are opened on the rollers 5, a placing frame 3 is arranged on the other side of the protective shell 1, and the placing frame 3 is used to place rolled garbage bags, a fixed plate 11 is arranged at one end of the protective shell 1, an arc plate 12 is fixedly connected to the fixed plate 11, a support frame 13 is fixedly connected to the top of the protective shell 1, a tension roller 14 is arranged on one side of the support frame 13, and both ends of the tension roller 14 are connected to two protective shells 1 through a connecting plate, a servo motor 15 is fixedly connected in the protective shell 1, a double-layer plate 16 is rotatably connected in the protective shell 1, and a winding head 6 is arranged on the double-layer plate 16, and the protective shell 1 A suction nozzle 7 is fixedly connected in the middle, a roller placing plate 21 is arranged on one side of the roller placing frame 2, and a roll 5 to be used is placed on the roller placing plate 21, and a guide rail 31 is arranged on one side of the placing frame 3, and the guide rail 31 is used to collect the roll 5 with the garbage bag rolled up that has fallen. The two circular plates in the double-layer plate 16 are fixedly connected by a support column, and a group of annular array bearings 161 are fixedly connected to the two circular plates of the double-layer plate 16, and a slider is arranged on the inner ring of the bearing 161. A first gear 162 is fixedly connected to one side of the double-layer plate 16. When in use, the operator first needs to lead the garbage bag out of the assembly line, and place it on the roll clamped at the top after passing through the tension roller 14. The garbage bag is wound on the roller 5, and then the vacuum pump is started. The suction nozzle 7 will extract the air inside the roller 5, so that the roller 5 can inhale the outside air through the air inlet. In this process, the garbage bag will be firmly adsorbed on the surface of the roller 5, and then the servo motor 15 will rotate. When the servo motor 15 rotates, it will drive the top winding head 6 to rotate. When the winding head 6 rotates, it will drive the roller 5 to rotate. When the roller 5 rotates, the garbage bag will be wound. At this time, the height of the control component 4 will also gradually increase. When the garbage bag on the roller 5 reaches the set thickness, the servo motor 15 will drive the double-layer plate 16 to rotate. At the same time, the winding head 6 and the servo motor 15 will rotate. The service motor 15 is separated, and during the rotation of the double-layer plate 16, on the one hand, the height of the roller 5 on which the garbage bag is rolled up will be gradually lowered, and at the same time, the position of the next roller 5 will be gradually raised. During the descent of the roller 5 on which the garbage bag is rolled up, the height of the control component 4 will drop. During the descent of the control component 4, the control component 4 will cut the garbage bag. After the garbage bag on the roller 5 on which the garbage bag is rolled up is cut off, the roller 5 on which the garbage bag is rolled up will fall onto the placement rack 3 due to the increase in the distance between the winding heads 6 on both sides, and the remaining part of the cut garbage bag will fall onto the new roller 5 located at the highest point to roll up the garbage bag.

Please refer to Figures 1 to 3 and 8. The present invention provides a technical solution: a rolling machine for processing garbage bags, wherein a control component 4 is provided on the support frame 13, and the control component 4 is used to cut the garbage bags and control the thickness of the garbage bags on the rolling roller 5. The control component 4 includes a lifting plate 41, and a group of evenly spaced first hydraulic rods 42 are fixedly connected to the bottom of the lifting plate 41, and a first spring 421 is provided inside the first hydraulic rod 42. A resistance plate 43 is fixedly connected to the bottom of the first hydraulic rod 42, and a mounting plate 431 is provided on one side of the resistance plate 43, and a heating wire 44 is connected to the mounting plate 431. The two ends of the lifting plate 41 are slidably connected to the limiting groove 131 of the support frame 13, and one end of the top of the lifting plate 41 is fixedly connected to a sliding rod 412, and the other end of the top of the lifting plate 41 is rotatably connected to a threaded rod 411. The threaded rod 411 The top of the support frame 13 is threadedly connected, and the sliding rod 412 is slidably connected to the top of the support frame 13. An auxiliary component 8 is fixedly connected in the protective shell 1. The auxiliary component 8 is used to control the movement state of the winding head 6 and the double-layer plate 16. The auxiliary component 8 includes a second hydraulic rod 81. The oil inlet of the second hydraulic rod 81 is connected to the first hydraulic rod 42 through a hose, and the oil outlet of the second hydraulic rod 81 is connected to the third hydraulic rod 82 through a hose. The second gear 811 is rotatably connected to the piston rod of the second hydraulic rod 81, and the third gear 821 is rotatably connected to the piston rod of the third hydraulic rod 82. A servo motor 15 is arranged between the second hydraulic rod 81 and the third hydraulic rod 82. When the garbage bag is rolled up, the height of the lifting plate 41 is first controlled by rotating the threaded rod 411. When the height of the lifting plate 41 is determined, the garbage bag is placed on the clamped On the top roller 5, the roller 5 will absorb the garbage bag and reel it in under the action of the vacuum pump and the servo motor 15. As the number of garbage bags on the roller 5 gradually increases, the diameter of the roller 5 will become larger and larger. As the diameter of the roller 5 becomes larger and larger, the roller 5 will begin to squeeze the contact plate 43. When the contact plate 43 is squeezed, the contact plate 43 will rise and squeeze the first hydraulic rod 42 at the top at the same time. When the first hydraulic rod 42 is squeezed, the oil inside the first hydraulic rod 42 will enter the second hydraulic rod 81 through the hose. When the oil in the second hydraulic rod 81 increases, the piston rod will be contracted while the excess oil inside will be squeezed into the third hydraulic rod 82 through the hose. When the oil in the third hydraulic rod 82 increases, the third hydraulic rod 82 will gradually extend the piston rod. When the diameter of the winding roller 5 reaches the expected position, the oil in the first hydraulic rod 42 causes the piston rod of the second hydraulic rod 81 to contract and disengage the second gear 811 from the gear of the servo motor 15 and the winding head 6. At the same time, the oil filled in the third hydraulic rod 82 causes the piston rod to extend and extends the third gear 821 between the gear of the servo motor 15 and the first gear 162. At this time, the servo motor 15 will not drive the winding head 6 to rotate, but will drive the double-layer plate 16 to rotate. During the rotation of the double-layer plate 16, the height of the winding roller 5 will drop. At this time, the first spring 421 inside the first hydraulic rod 42 will stretch and push the piston rod to drop the contact plate 43. During the drop of the contact plate 43, the heating wire 44 will contact the garbage bag to be wound, and the heating wire 44 will cut the garbage bag through high temperature.

Please refer to Figures 1 to 7.

When the winding head 6 rotates to the highest point, on the one hand, the trigger plate 63 will enter the arc plate 12, and on the other hand, the tail end of the winding head 6 will abut on the protective cover 71, so that the suction nozzle 7 can be connected to the winding head 6. When the suction nozzle 7 draws air, the air inside the winding head 6 will be sucked out, and the garbage bag will be adsorbed on the surface of the winding roller 5. When the double-layer plate 16 rotates, the arc plate 12 will continuously squeeze the trigger plate 63, so that the pressing plate 65 in the winding head 6 continues to press on the second spring 66, so that the distance between the two winding heads 6 is getting larger and larger. When the new winding roller 5 reaches the highest point, the distance between the two winding heads 6 is greater than the length of the winding roller 5. At this time, the winding roller 5 wrapped with the garbage bag will fall on the placement rack 3. When the double-layer plate 16 rotates again, the two winding heads 6 will be at the lowest position. At this time, the distance between the two winding heads 6 When the two winding heads 6 leave the curved plate 12, the second spring 66 will be restored and push the winding heads 6 out. When the winding heads 6 on both sides are close to each other, a new winding roller 5 is placed on the roller plate 21 in the roller frame 2. The two winding heads 6 are inserted into the two ends of the winding roller 5, the sealing ring 61 is tightly attached to the inside of the winding roller 5, and the two ends of the winding roller 5 are abutted against the blocking plate 62.
