Description
Technical Field
[0001] This utility model relates to the technical field of winding roll handling equipment, and more specifically, to a winding roll handling device for a winding film machine. Background Technology
[0002] A stretch wrapping machine (also known as a stretch packaging machine) is an automated / semi-automated packaging equipment. Its core function is to fix, dustproof, moistureproof and protect goods (such as pallets, cartons, parts, etc.) by evenly and tightly wrapping the stretch roll (i.e., stretch film) on the surface of goods, so as to facilitate warehousing and logistics transportation. The stretch roll needs to be moved to the work site or warehouse using a handling device.
[0003] The existing handling equipment has the following problems during use:
[0004] Firstly, since different goods have different heights, they need to be wrapped with winding rolls of different widths. Existing handling equipment cannot flexibly change its length according to the width of the winding roll and cannot be compatible with winding rolls of multiple widths. It is necessary to increase equipment investment. If subsequent business adds and uses winding rolls of different widths, the existing handling equipment may be directly eliminated, resulting in low equipment reuse rate.
[0005] Secondly, when existing handling devices transport the wrapping rolls to the work site or warehouse, if the space is too small to use hoisting equipment, manual handling is often required when unloading the wrapping rolls, which increases the workload. In view of this, we propose a wrapping roll handling device for wrapping film machines. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing a winding roll transport device for a stretch film machine to solve the problems of existing solutions.
[0007] To achieve the above objectives, this utility model provides a winding roll transport device for a stretch film machine, including a transport plate. The transport plate has a lifting mechanism at its center for lifting and lowering the winding roll. Multiple splicing mechanisms are provided on both sides of the transport plate and are interconnected. Specifically, the transport plate has two first sliding grooves symmetrically arranged on both sides. The multiple splicing mechanisms have identical structures, each splicing mechanism including a splicing plate. A first sliding strip is fixedly connected to one side of the splicing plate, and a second sliding groove is provided on the other side. The first sliding strip is slidably connected to the first sliding groove and also slidably connected to the second sliding groove on an adjacent splicing plate. The splicing plate also has two first slots symmetrically arranged at both ends of the top of the splicing plate. First guardrails are inserted into the first slots. Universal wheels are provided at the bottom of both the splicing plate and the transport plate to allow stable movement of the splicing plate and the transport plate for transporting the winding roll.
[0008] The beneficial effects of this utility model are:
[0009] 1) In the wrapping roll transport device of this wrapping film machine, two splicing plates are symmetrically slid into the two first slide grooves of the transport plate, and then the first slide bars of other splicing plates are inserted into the second slide grooves of the adjacent splicing plates. Then, the second guardrail is inserted into the second slot, and multiple first guardrails are inserted into the first slot, and the second guardrails and the first guardrails are connected to each other. Then, the protective frame is inserted into the third slot, so as to flexibly change the width of the transport device itself according to the width of the wrapping roll, be compatible with wrapping rolls of multiple widths, and improve the versatility and reusability of the equipment.
[0010] 2) In the wrapping film machine's wrapping roll handling device, the screw is rotated by turning the handle, which in turn causes the moving block to slide against the inner wall of the fixed shell, thereby moving the connecting rod to gradually lift the lifting plate. Finally, the wrapping roll slides down the lifting plate and leaves the handling plate and splicing plate. In this way, when the space is small and hoisting equipment cannot be used, there is no need for manual unloading, reducing the workload.
[0011] Based on the above technical solution, the present invention can be further improved as follows:
[0012] As a further improvement to this technical solution, the transport plate is provided with two sets of second slots, which are symmetrically arranged at both ends of the top of the transport plate. Each set of second slots is connected to a second guardrail. The second guardrail is provided with two third sliding grooves, which are symmetrically arranged at both ends of the second guardrail. A second sliding bar is fixedly connected to one end of the first guardrail, and a fourth sliding groove is provided at the other end of the first guardrail. The second sliding bar is slidably connected to the third sliding groove and to the fourth sliding groove on the adjacent first guardrail.
[0013] The beneficial effect of adopting the above-mentioned further solution is that by inserting the second guardrail into the second slot, the two sides of the transport plate can be protected to prevent the winding roll from falling off the side of the transport plate. Furthermore, by inserting the second slide bar of one first guardrail into the third slide groove, and then inserting the second slide bars of other first guardrails into the adjacent fourth slide grooves in sequence, the second guardrail and multiple first guardrails can be connected end to end to prevent winding rolls of different lengths from falling off the side of the transport plate and splicing plate.
[0014] As a further improvement to this technical solution, a set of third slots is provided on one side of the top of the splicing plate. Protective frames are inserted into the two sets of third slots away from the transport plate. A fifth sliding groove is provided on one side of the first guardrail and the second guardrail. Two third sliding bars are fixedly connected to the protective frame. The two third sliding bars are symmetrically arranged at both ends of the protective frame, and the third sliding bars are slidably connected to the fifth sliding groove.
[0015] The beneficial effect of adopting the above-mentioned further solution is that, by setting up the protective frame, the protective frame is inserted into the third slot to protect the winding roll placed on the transport plate and splicing plate and prevent the winding roll from slipping off. Then, the third slide bar at the end of the protective frame slides into the corresponding fifth slide groove, thereby improving the structural stability of the protective frame.
[0016] As a further improvement to this technical solution, the top center of the conveying plate is provided with an installation groove, the lifting mechanism includes a lifting plate, the lifting plate is hinged in the installation groove, the top of the lifting plate is provided with multiple grooves, and the multiple grooves are distributed in a linear array, and rollers are rotatably connected inside the grooves.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, by setting up the lifting plate and rollers, when the lifting plate is lifted, one side of the lifting plate gradually rises, and the winding roll located at the top of the lifting plate rises together with the lifting plate until the winding roll slides down along the lifting plate under the action of gravity. At this time, the rollers rotate, reducing the friction between the winding roll and the lifting plate, making it easier for the winding roll to slide down and detach from the transport plate and splicing plate.
[0018] As a further improvement to this technical solution, the lifting mechanism also includes a fixed shell. The top of the fixed shell is fixedly connected to the bottom of the transport plate. A handle is rotatably connected to one end of the fixed shell. A screw is fixedly connected to the output end of the handle through the fixed shell. One end of the screw is rotatably connected to one end of the fixed shell. A movable block is threadedly connected to the surface of the screw. The surface of the movable block is slidably connected to the inner wall of the fixed shell. A connecting rod is hinged to the top of the movable block. The other end of the connecting rod is hinged to the bottom of the lifting plate.
[0019] The beneficial effect of adopting the above-mentioned further solution is that, through the arrangement of the handle, screw, moving block and connecting rod, the handle is rotated, which drives the screw to rotate, thereby driving the moving block to slide against the inner wall of the fixed shell, thereby driving the connecting rod to move, gradually raising the lifting plate, and finally causing the winding roll to slide down along the lifting plate and leave the transport plate and splicing plate.
[0020] As a further improvement to this technical solution, the lifting plate is fixedly connected to two fixing blocks, which are symmetrically distributed at both ends of one side of the lifting plate. Two slots are opened on one side of the mounting groove, and the fixing blocks are engaged with the slots.
[0021] The beneficial effect of adopting the above-mentioned further solution is that, by setting the fixing block and the slot, the fixing block can be locked in the slot, which can support the lifting plate in the installation slot.
[0022] As a further improvement to this technical solution, a ramp is hinged to one end of the transport plate, a fixed shaft is fixedly connected to the connection between the transport plate and the ramp, a stop is rotatably connected to one end of the fixed shaft, and one side of the stop contacts one side of the transport plate.
[0023] The beneficial effect of adopting the above-mentioned further solution is that, by setting the inclined plate, when the winding roll slides down along the lifting plate, it will continue to slide down along the inclined plate, preventing the winding roll from falling directly to the ground and providing a certain degree of protection for the winding roll. In addition, by using the stop block to block the inclined plate, the inclined plate can be erected when not in use, avoiding the inclined plate occupying space. When using the inclined plate, the stop block can be rotated to move away from the inclined plate, and then the inclined plate can be rotated so that the end of the inclined plate contacts the ground to unload the winding roll.
[0024] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-4 As shown, this embodiment provides a wrapping roll transport device for a wrapping film machine, including a transport plate 1. A lifting mechanism 2 for lifting the wrapping roll and causing it to slide down is disposed at the center of the transport plate 1. Multiple splicing mechanisms 3 are disposed on both sides of the transport plate 1, and the multiple splicing mechanisms 3 are interconnected. Wherein:
[0033] The transport plate 1 has two first sliding grooves, which are symmetrically arranged on both sides of the transport plate 1. The multiple splicing mechanisms 3 have the same structure. The splicing mechanism 3 includes a splicing plate 31. A first sliding strip 32 is fixedly connected to one side of the splicing plate 31, and a second sliding groove is opened on the other side of the splicing plate 31. The first sliding strip 32 is slidably connected to the first sliding groove and to the second sliding groove on the adjacent splicing plate 31. The splicing plate 31 also has two first slots, which are symmetrically arranged at both ends of the top of the splicing plate 31. A first guardrail 33 is inserted into the first slot. The bottom of the splicing plate 31 and the transport plate 1 are equipped with casters, so that the splicing plate 31 and the transport plate 1 can move effectively and stably to transport the winding roll.
[0034] Furthermore, the transport plate 1 has two sets of second slots, symmetrically arranged at both ends of the top of the transport plate 1. Each set of second slots is fitted with a second guardrail 4. The connection between the first slot and the first guardrail 33, as well as the connection between the second slot and the second guardrail 4, are fixed with bolts to ensure the structural stability of the first guardrail 33 and the second guardrail 4. The second guardrail 4 has two third sliding grooves, symmetrically arranged at both ends of the second guardrail 4. One end of the first guardrail 33 is fixedly connected to a second sliding strip 34, and the other end of the first guardrail 33 has a fourth sliding groove. The second sliding strip 34 is slidably connected to the third sliding groove and to the fourth sliding groove on the adjacent first guardrail 33. By inserting the second guardrail 4 into the second slot, the two sides of the transport plate 1 can be protected to prevent the winding roll from falling off the side of the transport plate 1. The second sliding strip 34 of one first guardrail 33 is inserted into the third sliding groove, and the second sliding strip 34 of the other first guardrail 33 is inserted into the adjacent fourth sliding groove in sequence. This connects the second guardrail 4 and multiple first guardrails 33 end to end to prevent winding rolls of different lengths from falling off the side of the transport plate 1 and the splicing plate 31.
[0035] Furthermore, a set of third slots is provided on one side of the top of the splicing plate 31. The two sets of third slots away from the transport plate 1 are each connected to a protective frame 5. The first guardrail 33 and the second guardrail 4 are each provided with a fifth sliding groove. The protective frame 5 is fixedly connected to two third sliding strips 6. The two third sliding strips 6 are symmetrically arranged at both ends of the protective frame 5, and the third sliding strips 6 are slidably connected to the fifth sliding groove. A clamping structure can also be provided on the protective frame 5 to limit the winding roll. This is existing technology and will not be described in detail. By setting the protective frame 5, the protective frame 5 is inserted into the third slot to protect the winding roll placed on the transport plate 1 and the splicing plate 31 and prevent the winding roll from slipping. Then, the third sliding strips 6 at the ends of the protective frame 5 are locked in the corresponding fifth sliding groove, which improves the structural stability of the protective frame 5.
[0036] Furthermore, a mounting groove is provided at the center of the top of the conveying plate 1. The lifting mechanism 2 includes a lifting plate 21, which is hinged in the mounting groove. Multiple grooves are provided on the top of the lifting plate 21, and these grooves are arranged in a linear array. Rollers 22 are rotatably connected inside the grooves. Through the arrangement of the lifting plate 21 and the rollers 22, when the lifting plate 21 is lifted, one side of the lifting plate 21 gradually rises. The winding coil located at the top of the lifting plate 21 rises along with the lifting plate 21 until, under the action of gravity, the winding coil slides downwards along the lifting plate 21. At this time, the rollers 22 rotate, as... Figure 3 As shown, the friction between the winding roll and the lifting plate 21 is reduced, making it easier for the winding roll to slide down and detach from the transport plate 1 and the splicing plate 31.
[0037] Furthermore, the lifting mechanism 2 also includes a fixed housing 23. The top of the fixed housing 23 is fixedly connected to the bottom of the transport plate 1. A handle 24 is rotatably connected to one end of the fixed housing 23. The handle 24 can be replaced by a power device, such as a motor. A screw 25 is fixedly connected to the output end of the handle 24 through the fixed housing 23. One end of the screw 25 is rotatably connected to one end of the fixed housing 23. A moving block 26 is threadedly connected to the surface of the screw 25. The surface of the moving block 26 is slidably connected to the inner wall of the fixed housing 23. A connecting rod 27 is hinged to the top of the moving block 26. The other end of the connecting rod 27 is hinged to the bottom of the lifting plate 21. Through the arrangement of the handle 24, screw 25, moving block 26, and connecting rod 27, as shown in the figure... Figure 4 As shown, rotating the handle 24 causes the screw 25 to rotate, which in turn causes the moving block 26 to slide against the inner wall of the fixed shell 23, thereby causing the connecting rod 27 to move and slowly lift the lifting plate 21. Finally, the winding roll slides down the lifting plate 21 and leaves the transport plate 1 and splicing plate 31.
[0038] Furthermore, the lifting plate 21 is fixedly connected to two fixing blocks 28. The two fixing blocks 28 are symmetrically distributed at both ends of one side of the lifting plate 21. Two slots are opened on one side of the mounting groove. The fixing blocks 28 are engaged with the slots. By setting the fixing blocks 28 and the slots, the fixing blocks 28 are engaged in the slots, which can support the lifting plate 21 in the mounting groove.
[0039] Furthermore, a ramp 7 is hinged to one end of the transport plate 1, and a fixed shaft 8 is fixedly connected to the connection between the transport plate 1 and the ramp 7. A stop block 9 is rotatably connected to one end of the fixed shaft 8. One side of the stop block 9 contacts one side of the transport plate 1. With the ramp 7, when the winding roll slides down along the lifting plate 21, it will continue to slide down along the ramp 7, preventing the winding roll from falling directly to the ground and providing a certain degree of protection for the winding roll. In addition, by using the stop block 9 to block the ramp 7, the ramp 7 can be erected when not in use, avoiding the ramp 7 from occupying space. When using the ramp 7, the stop block 9 is rotated to move away from the ramp 7, so that the ramp 7 can be rotated and the end of the ramp 7 contacts the ground to unload the winding roll.
[0040] In summary, the working principle of this solution is as follows:
[0041] When it is necessary to use this conveying device to move winding rolls of different widths, two splicing plates 31 are symmetrically slid into the two first sliding grooves of the conveying plate 1, and then the first sliding strips 32 of the other splicing plates 31 are inserted into the second sliding grooves of the adjacent splicing plates 31, so that the conveying plate 1 and multiple splicing plates 31 are connected to each other, so as to adjust the width of the entire conveying device according to the winding rolls of different widths to be moved. Then, the second guardrail 4 is inserted into the second slot, and multiple first guardrails 33 are inserted into the first slot, and the second guardrail 4 and the first guardrail 33 are connected to each other. Then, the protective frame 5 is inserted into the third slot, thereby forming a new conveying device.
[0042] When unloading the winding coil is required, first pull out the second guardrail 4 and multiple first guardrails 33 on the same side as the inclined plate 7, and rotate the stop block 9 to make it leave the inclined plate 7. Then rotate the inclined plate 7 so that the end of the inclined plate 7 contacts the ground. Then rotate the handle 24 to drive the screw 25 to rotate, which in turn drives the moving block 26 to slide against the inner wall of the fixed shell 23, which in turn drives the connecting rod 27 to move, slowly lifting the lifting plate 21. Finally, the winding coil slides down the lifting plate 21 and leaves the transport plate 1 and splicing plate 31.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
