Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a PVC raw material ton bag hoisting equipment. Background Art

[0002] Cardboard is the main raw material for making bank cards, subway cards, SIM cards and other cards. Cards are formed by stacking and pressing individual cardboards. The raw materials for making cardboard include polyvinyl chloride resin, colorants and additives.

[0003] When processing cardboard, polyvinyl chloride resin particles are fed into a negative pressure feeding tank, and then fed into a melting device through the negative pressure feeding tank to be melted in preparation for making cardboard. After the polyvinyl chloride resin particles are processed, they are packaged in ton bags, which requires the use of lifting equipment to lift the ton bags of polyvinyl chloride resin particles above the negative pressure feeding tank. The staff climbs up the ladder to cut the bottom of the ton bag so that the polyvinyl chloride resin particles in the ton bag can be fed into the negative pressure feeding tank. When the existing lifting equipment is used to lift the ton bag, the slings on both sides of the ton bag are manually hung on the hooks of the lifting equipment, and the ton bag is lifted by the lifting equipment. Although this method can lift the ton bag, it still has the following defects in actual use:

[0004] Since the slings on both sides of the ton bag are mostly fixed to the bag body by seams, if the slings and the bag body are separated during the lifting process, the ton bag will fall off during the lifting process, which may cause physical harm to the workers under the lifting equipment. In addition, after the ton bag is lifted above the negative pressure loading tank, the workers need to climb up the ladder to cut the bottom of the ton bag, which is troublesome;

[0005] Therefore, the present application proposes a PVC raw material ton bag lifting equipment. Utility Model Content

[0030] Embodiment 1

[0031] In order to solve the technical problems in the background technology, the following PVC raw material ton bag lifting equipment is provided:

[0032] Combination Figure 1-Figure 6 As shown, the utility model provides a PVC raw material ton bag lifting equipment, including a guide rail 1, which is horizontally installed on a wall 2, a negative pressure feeding tank 3 with an open top is placed on one side of the wall 2 and below the guide rail 1, a moving plate 11 is slidably installed on the guide rail 1 in the horizontal direction, and an electromagnetic slider 12 connected to the moving plate 11 is fixedly installed on the guide rail 1; a mounting frame 4 is fixedly installed at the bottom of the moving plate 11, a winding roller 41 is rotatably installed on the mounting frame 4, a lifting rope 42 is wound around the winding roller 41, and a mounting bracket 12 is fixedly installed at the end of the lifting rope 42 A plate 43 is provided, a hook 44 is fixed at the middle position of the bottom of the mounting plate 43, a motor 45 for driving the winding roller 41 to rotate is fixedly installed on the mounting frame 4; connecting ropes 5 are fixedly installed at both ends of the bottom of the mounting plate 43, a protective bottom plate 51 is fixed at the bottom of the two connecting ropes 5, a through hole 52 is opened in the middle of the protective bottom plate 51, support plates 53 are symmetrically fixed on the protective bottom plate 51 and located in the through hole 52, a bag-splitting mechanism 6 is installed in the through hole 52 and between the opposite sides of the two support plates 53, and the bag-splitting mechanism 6 is used to slash the bottom of the ton bag.

[0033] When hoisting a ton bag, a force is applied to the protective bottom plate 51 to deform the two connecting ropes 5, and the slings on both sides of the ton bag are hung on the hooks 44. The motor 45 is controlled to start, so that the winding roller 41 rotates on the mounting frame 4 to wind the sling rope 42, so that the ton bag can be lifted and moved to the top of the negative pressure feeding tank 3. The electromagnetic slider 12 is used to make the movable plate 11 slide on the guide rail 1, so that the ton bag can be moved to the top of the negative pressure feeding tank 3, and the ton bag of PVC raw materials can be hoisted.

[0034] Through the design of the protective bottom plate 51, when the ton bag is slightly lifted, a force is applied to the protective bottom plate 51 so that it is located below the ton bag, thereby achieving a protective effect on the bottom of the ton bag. If the sling and the bag body are separated, the ton bag contacts the protective bottom plate 51, thereby achieving a supporting effect on the ton bag through the protective bottom plate 51, effectively preventing the ton bag from falling downward and causing physical injuries to the workers under the lifting equipment, thereby improving safety.

[0040] Embodiment 3

[0041] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0042] In this embodiment, a reset member 7 connected to the rack 653 is installed on the protective bottom plate 51, which is used to slide and reset the rack 653 along the sliding rod 652, so that the blade 64 rotates around the rotating shaft 62 and is hidden to one side of the mounting block 61; the reset member 7 includes a spring 71 sleeved on the outside of the sliding rod 652, and the two ends of the spring 71 are respectively fixed to the protective bottom plate 51 and the rack 653. When in use, when the pull rope 654 is pulled to drive the rack 653 to move outside the sliding rod 652, the spring 71 is subjected to force When deformation occurs and the force on the pull rope 654 is cancelled, the spring 71 returns to its natural state, thereby pushing the rack 653 to slide and reset along the sliding rod 652. By setting the reset member 7, the rack 653 can slide and reset along the sliding rod 652, so that the blade 64 can rotate around the rotating shaft 62 and be hidden to one side of the mounting block 61, effectively preventing the end of the blade 64 from extending below the mounting block 61. When the worker pulls the protective bottom plate 51, the blade 64 accidentally scratches the worker, causing injury to the worker.

[0043] In this embodiment, a bracket 8 is fixedly installed on the protective bottom plate 51 and located on the outer side of the through hole 54, and a guide pulley 81 is rotatably installed on the bracket 8. The pull rope 654 is wound around the top of the guide pulley 81, and the pull rope 654 does not contact the inner wall of the through hole 54. Specifically, when the pull rope 654 is pulled, the pull rope 654 does not contact the inner wall of the through hole 54. Through the design of the guide pulley 81, when the pull rope 654 is pulled, the guide pulley 81 rotates on the bracket 8, and the pull rope 654 does not contact the inner wall of the through hole 54. On the one hand, the rotation of the guide pulley 81 is conducive to the staff to pull the pull rope 654 smoothly, thereby facilitating the pulling of the rack 653 to move. On the other hand, it effectively avoids the friction between the pull rope 654 and the inner wall of the through hole 54, which causes the pull rope 654 to wear.
