A cutting device for bubble bag processing

Abstract

This utility model discloses a cutting device for processing bubble bags, including a worktable, a cutting component, a transmission component, a collecting component, and a compaction component. The worktable is fixedly connected to a support. The cutting component is used to cut the bubble bags. The collecting component is used to collect the remaining material from the cut bubble bags. Through the compaction component, when the first transmission wheel rotates, it causes the bidirectional screw to rotate, thereby causing two rollers to press tightly against the bubble bag and move towards the two edges of the bubble bag. The spring in the mounting block generates a downward elastic force on the connecting block, ensuring that the rollers remain in close contact with the worktable surface. When the bubble bag passes under the rollers, the rollers, under the action of the springs, compact the two sides of the bubble bag at the cut point, expelling some of the air inside the bubble bag. This keeps the bubble bag stable during cutting, preventing the cutting position from shifting due to bubble bulging and ensuring a neat cut edge.

Description

Technical Field

[0001] This utility model relates to the field of bubble bag processing technology, and in particular to a cutting device for bubble bag processing. Background Technology

[0002] Bubble bags are a common cushioning packaging material used for cushioning and protecting products during logistics and transportation. They are widely used in the transportation packaging of electronic products, precision instruments, and other products. However, bubble bags are often produced in large sizes and need to be cut into appropriate lengths and widths according to actual usage requirements in order to be used for packaging different products, such as protective packaging of fragile items like electronic products, glassware, and ceramics.

[0003] The bubble bag cutting equipment disclosed in this patent publication number "CN214981528U" processes bubble bags by sequentially setting up a feeding roller, a pressing roller, a cutting device and a packaging device on a worktable. The packaging device can package the cut bubble bags.

[0004] However, in actual use, during the cutting process, the expansion of air inside the bubble bag will make the surface of the bubble bag uneven. The bubble bag is easily affected by the cutting force and will shift in position. As a result, the bubble bag is prone to position shift during cutting, and it is difficult to ensure the neatness of the cut edge, which in turn affects the quality of the bubble bag.

[0005] Accordingly, this application proposes a cutting device for bubble wrap processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for bubble bag processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cutting device for processing bubble bags includes a worktable, a cutting assembly, a transmission assembly, a collecting assembly, and a compaction assembly, wherein the worktable is fixedly connected to a support.

[0009] The cutting assembly is used to cut the bubble wrap;

[0010] The collection component is used to collect the remaining material from the cut bubble wrap.

[0011] The compaction component is used to compact the cut portion of the bubble wrap.

[0012] The transmission assembly is used to transmit power to the various components.

[0013] Preferably, the cutting assembly includes a cutting frame, a lead screw, a sliding plate, a cutting blade, two slides, two mounting brackets, two electric telescopic rods, and two pressure blocks; the cutting frame is fixedly installed on the workbench, the two slides are respectively provided on the cutting frame, the lead screw is rotatably connected in the slide, the sliding plate is slidably connected on the two slides, and the cutting blade is fixedly installed on the sliding plate.

[0014] Preferably, the two mounting brackets are fixedly mounted on the cutting frame, the two electric telescopic rods are fixedly mounted on the mounting brackets, the two pressure blocks are fixedly connected to the output ends of the two electric telescopic rods, and the slide plate is threadedly connected to the lead screw.

[0015] Preferably, the collecting assembly includes two side plates, two cam rollers, two gears, a first bevel gear, and a second bevel gear. The two side plates are fixedly connected to both sides of the workbench opening, the two cam rollers are rotatably connected to the side plates, the two gears are rotatably connected between the two side plates, the first bevel gear is rotatably connected below the workbench, and the second bevel gear is rotatably connected to the side plates.

[0016] Preferably, the two gears are meshed with each other, and the two gears are respectively fixedly connected to two cam rollers. The first bevel gear is fixedly connected to the lead screw, the second bevel gear is fixedly connected to the cam roller, the first bevel gear and the second bevel gear are meshed. A collection box is slidably connected below the two side plates. A motor is fixedly installed on the bracket, and the motor drive shaft is fixedly connected to the lead screw.

[0017] Preferably, the compaction assembly includes a slide rod, a bidirectional screw, two sliders, two mounting blocks, two rollers, two springs, and two connecting blocks. The slide rod is fixedly connected inside the cutting frame, the bidirectional screw is rotatably connected inside the cutting frame, the two sliders are threaded to both sides of the thread of the bidirectional screw, and the two sliders are slidably connected to the slide rod.

[0018] Preferably, the mounting block is fixedly connected to the slider, the connecting block is slidably connected inside the mounting block, one end of the spring is fixedly connected to the connecting block, and the other end is fixedly connected to the mounting block, the roller is rotatably connected between the two connecting blocks, and the roller is in close contact with the surface of the worktable.

[0019] Preferably, the transmission assembly consists of a belt, a first transmission wheel, and a second transmission wheel. The first transmission wheel is rotatably connected to the side plate, and the second transmission wheel is rotatably connected to the cutting frame. The belt passes through the workbench and wraps around the outside of the first and second transmission wheels. The first transmission wheel is fixedly connected to the cam roller, and the second transmission wheel is fixedly connected to the bidirectional screw.

[0020] This utility model has the following beneficial effects:

[0021] 1. Through the compaction assembly, when the first drive wheel rotates, it causes the bidirectional screw to rotate, thereby causing the two rollers to press tightly against the bubble bag and move towards the sides of the bubble bag. The spring inside the mounting block generates a downward elastic force on the connecting block, keeping the rollers in close contact with the worktable surface. When the bubble bag passes under the rollers, the rollers, under the action of the springs, compact the sides of the bubble bag at the cutting point, expelling some of the air inside the bubble bag. This keeps the bubble bag stable during cutting, preventing the cutting position from shifting due to bubble bulging and ensuring a clean cutting edge.

[0022] Second, through the collection component, when the cutting component completes its work, the lead screw rotates to retract the cutter, thereby causing the first bevel gear to drive the second bevel gear to rotate. Under the action of the gears, the two cam rollers rotate in opposite directions. When the protrusions of the two cam rollers come close to each other, the remaining material from the bubble wrap is clamped between the two protrusions. As the cam rollers continue to rotate, the protrusions exert a downward dragging force on the remaining material, guiding the remaining material from the bubble wrap into the collection box below the side plate. This achieves coordinated operation of cutting and remaining material collection, while ensuring that the remaining material can be collected in a timely manner, avoiding the accumulation of remaining material from affecting the continuous cutting process of the bubble wrap.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figure 1-6 A cutting device for processing bubble bags includes a worktable 1, a cutting assembly, a transmission assembly, a collecting assembly, and a compaction assembly. The worktable 1 is fixedly connected to a support 4.

[0033] The cutting assembly is used to cut bubble wrap;

[0034] The collection component is used to collect the remaining material from the cut bubble wrap.

[0035] The compaction assembly is used to compact the cut edges of bubble wrap.

[0036] The transmission assembly is used to transmit power from the various components.

[0037] The cutting assembly includes a cutting frame 2, a lead screw 21, a sliding plate 211, a cutting blade 212, two slides 22, two mounting brackets 23, two electric telescopic rods 231, and two pressure blocks 232. The cutting frame 2 is fixedly installed on the workbench 1. The two slides 22 are respectively provided on the cutting frame 2. The lead screw 21 is rotatably connected in the slides 22. The sliding plate 211 is slidably connected to the two slides 22. The cutting blade 212 is fixedly installed on the sliding plate 211. The sliding plate 211 can drive the cutting blade 212 to slide up and down in the slides 22, thereby cutting the bubble bag below.

[0038] Two mounting brackets 23 are fixedly mounted on the cutting frame 2, two electric telescopic rods 231 are fixedly mounted on the mounting brackets 23, two pressure blocks 232 are fixedly connected to the output ends of the two electric telescopic rods 231, and the slide plate 211 is threadedly connected to the lead screw 21. The rotation of the lead screw 21 can drive the slide plate 211 to rotate, thereby causing the slide plate 211 to drive the cutter 212 to cut the bubble bag. The descent of the electric telescopic rod 231 can press and fix the bubble bag, preventing the bubble bag from shifting during cutting.

[0039] A motor 5 is fixedly installed on the bracket 4. The drive shaft of the motor 5 is fixedly connected to the lead screw 21. The motor 5 can drive the lead screw 21 to rotate, thereby making the cutting assembly work.

[0040] In this embodiment, the electric telescopic rod 231 first drives the pressure block 232 to clamp the bubble bag on the worktable 1 to prevent the bubble bag from shifting during cutting. Then, the motor 5 is started to rotate the lead screw 21, which causes the slide plate 211 to drive the cutter 212 to slide downward in the slide groove 22, thereby cutting the bubble bag below.

[0041] Example 2

[0042] Unlike Example 1, referring to Figure 3 , Figure 5 and Figure 6 This embodiment also has the following further features:

[0043] The compaction assembly includes a slide rod 8, a bidirectional screw 81, two sliders 811, two mounting blocks 812, two rollers 8121, two springs 8122, and two connecting blocks 8123. The slide rod 8 is fixedly connected inside the cutting frame 2, and the bidirectional screw 81 is rotatably connected inside the cutting frame 2. The two sliders 811 are threadedly connected to both sides of the thread of the bidirectional screw 81, and the two sliders 811 are slidably connected to the slide rod 8. The slide rod 8 provides guidance for the sliding of the sliders 811. When the bidirectional screw 81 rotates, it can drive the two sliders 811 to move closer or further apart.

[0044] Mounting block 812 is fixedly connected to slider 811, connecting block 8123 is slidably connected inside mounting block 812, one end of spring 8122 is fixedly connected to connecting block 8123, and the other end is fixedly connected to mounting block 812, and roller 8121 is rotatably connected between the two connecting blocks 8123. Roller 8121 is in close contact with the surface of worktable 1. When the two sliders 811 drive the two mounting blocks 812 to move towards the two edges of the bubble bag, the two rollers 8121 move towards the two edges of the bubble bag. The spring 8122 inside mounting block 812 generates a downward elastic force on connecting block 8123, so that roller 8121 is always in close contact with the surface of worktable 1. When the bubble bag passes under roller 8121, roller 8121, under the action of spring 8122, compacts the two sides of the bubble bag at the cutting point, expelling some of the air inside the bubble bag, so that the bubble bag remains stable during cutting, avoiding the cutting position shift due to bubble bulging, and ensuring a neat cutting edge.

[0045] In this embodiment, during the downward cutting process of the cutting assembly, the bidirectional screw 81 rotates, causing the two rollers 8121 to press tightly against the bubble bag and move towards the edges of the bubble bag. The spring 8122 inside the mounting block 812 generates a downward elastic force on the connecting block 8123, ensuring that the rollers 8121 remain in close contact with the surface of the worktable 1. When the bubble bag passes under the rollers 8121, the rollers 8121, under the action of the spring 8122, compress the two sides of the bubble bag at the cutting point, expelling some of the air inside the bubble bag. This keeps the bubble bag stable during cutting, preventing the cutting position from shifting due to bubble bulging and ensuring a neat cutting edge.

[0046] It should be noted that the two rollers 8121 correspond to the position of the upper cutting blade 212. When the cutting blade 212 descends to cut the bubble bag, the two rollers 8121 roll to the outside of the bubble bag to prevent the compaction component from limiting the cutting blade 212.

[0047] Example 3:

[0048] Reference Figures 2-4 Compared to Embodiment 1 and Embodiment 2, in this embodiment:

[0049] The collecting assembly includes two side plates 3, two cam rollers 31, two gears 32, a first bevel gear 33, and a second bevel gear 34. The two side plates 3 are fixedly connected to both sides of the opening of the workbench 1. The two cam rollers 31 are rotatably connected to the side plates 3. The two gears 32 are rotatably connected between the two side plates 3 and mesh with each other. The two gears 32 are fixedly connected to the two cam rollers 31. Thus, when one of the cam rollers 31 rotates, the two cam rollers 31 can rotate in opposite directions through the meshing of the two gears 32. The first bevel gear 33 is rotatably connected to the bottom of the workbench 1, and the second bevel gear 34 is rotatably connected to the side plate 3.

[0050] The first bevel gear 33 is fixedly connected to the lead screw 21, and the second bevel gear 34 is fixedly connected to the cam roller 31. The first bevel gear 33 and the second bevel gear 34 are meshed together. When the lead screw 21 drives the first bevel gear 33 to rotate, the second bevel gear 34 can drive the cam roller 31 to rotate, thereby realizing the coordinated work of the cutting component and the collecting component. A collecting box 7 is slidably connected below the two side plates 3 for collecting the remaining material of the bubble bag after cutting.

[0051] The transmission assembly consists of a belt 6, a first transmission wheel 61, and a second transmission wheel 62. The first transmission wheel 61 is rotatably connected to the side plate 3, and the second transmission wheel 62 is rotatably connected to the cutting frame 2. The belt 6 passes through the workbench 1 and wraps around the outside of the first transmission wheel 61 and the second transmission wheel 62. The first transmission wheel 61 is fixedly connected to the cam roller 31, and the second transmission wheel 62 is fixedly connected to the bidirectional screw 81. Thus, when the second bevel gear 34 drives the cam roller 31 to rotate, the first transmission wheel 61 can cause the second transmission wheel 62 to rotate through the belt 6, thereby causing the bidirectional screw 81 to rotate, thus realizing the coordinated work of the cutting assembly, the compaction assembly, and the collection assembly.

[0052] In this embodiment, when the cutting assembly completes its work, the lead screw 21 rotates, causing the cutter 212 to retract. This, in turn, causes the first bevel gear 33 to drive the second bevel gear 34 to rotate. Under the action of the gear 32, the two cam rollers 31 rotate in opposite directions. When the protrusions of the two cam rollers 31 come close to each other, the remaining material from the bubble bag is clamped between the two protrusions. As the cam rollers 31 continue to rotate, the protrusions exert a downward dragging force on the remaining material, guiding it into the collection box 7 below the side plate 3. This achieves coordinated operation of cutting and material collection, while ensuring that the remaining material can be collected in a timely manner, preventing the accumulation of material from affecting the continuous cutting process of the bubble bag.

[0053] It should be noted that before cutting the bubble bag, the edge of the bubble bag to be cut should be inserted between the two cam rollers 31 so that the remaining material can be quickly recycled after cutting.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
