Description

Technical Field

[0001] This utility model belongs to the field of packaging-related technical technology, and in particular relates to an antistatic PE film cutting device. Background Technology

[0002] Antistatic PE film is a polyethylene film with special antistatic properties. Its core characteristics and functions are mainly reflected in the following aspects: Antistatic properties: Through material modification or process treatment, it has low surface resistance and volume resistance, effectively preventing static electricity accumulation and discharge, and avoiding damage to sensitive items such as electronic components and flammable and explosive materials caused by static electricity. Physical and chemical properties: It has high wear resistance, corrosion resistance, low density, and good processability, and can adapt to complex molding requirements such as cutting and welding. It is also resistant to high temperatures (some products can withstand 120℃) and moisture, and its performance is stable for 960 hours in an environment of 75℃ and 95% humidity. Protective function: It also has dustproof, moisture-proof, and scratch-proof properties, protecting the surface of products from contamination or damage during transportation or storage, and is especially suitable for high-precision products such as electronic screens and metal sheets. When using antistatic PE film to package corresponding products, it needs to be cut into the corresponding size to meet the corresponding packaging requirements. However, the following drawbacks still exist in actual cutting operations:

[0003] First, during the unwinding and cutting of PE film, static electricity may be generated due to friction caused by unwinding, moving, transporting, and clamping. Static electricity may attract dust or damage the film itself and the packaged items.

[0004] Secondly, the required PE film width varies depending on the type of packaging material, so it needs to be cut to the corresponding width for packaging; however, it is not possible to choose different cutting widths based on different packaging materials.

[0005] Finally, the cutting of PE film involves cutting the PE film unwound from the master roll and winding it into smaller rolls. When these smaller rolls are wound to a certain extent, they need to be cut from the master roll. However, the cutting process is different from the transverse cutting when dividing into narrow rolls; it requires longitudinal cutting, which can easily produce burrs, stringing, and other phenomena, affecting the quality.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an antistatic PE film cutting device, including an unwinding assembly, a guiding assembly, an antistatic assembly, a cutting assembly, a severing assembly, a rewinding assembly, and a worktable. The unwinding assembly, one guiding assembly, an antistatic assembly, another guiding assembly, a cutting assembly, a stabilizing assembly, a severing assembly, and a rewinding assembly are arranged sequentially above the worktable in the direction of PE film unwinding.

[0009] The guide assembly includes two columns fixed to the upper end of the workbench, and two chrome-plated metal rollers distributed vertically are rotatably connected between the two columns.

[0010] The static elimination component includes two columns three fixed to the upper part of the workbench, and an ion air bar is fixed between the two columns three, with the outlet of the ion air bar facing downward.

[0011] The cutting assembly includes two columns four fixed to the upper part of the workbench, and a screw is fixed between the two columns four. The screw is externally threaded with equally spaced threaded rings, and a right-angle cutter is fixed at the bottom end of the threaded rings.

[0012] The cutting assembly includes an inverted U-shaped bracket fixed on the worktable, a cylinder fixed at the top of the bracket, and a piston rod at the telescopic end of the cylinder passing through the horizontal part of the bracket and fixed with a hot melt cutter.

[0013] The winding assembly includes a vertical plate fixed above the workbench, a winding shaft rotatably connected to the side of the vertical plate, and winding drums evenly distributed on the winding shaft threadedly connected to the winding shaft.

[0014] Furthermore, the unwinding assembly includes two columns fixed to the upper end of the workbench, and an unwinding roller is rotatably connected between the two columns. The unwinding roller is higher than the height of the chrome-plated metal roller, and a PE film master roll is wound around the unwinding roller.

[0015] Furthermore, both ends of the two chrome-plated metal rollers extend beyond the second column, and a collar is fitted around the same end of the two chrome-plated metal rollers extending beyond the second column. A grounding wire is fixedly connected to the bottom end of the collar, and the bottom end of the grounding wire is grounded.

[0016] Furthermore, the cutting edge of the right-angle cutter faces the unwinding assembly, and the inner right angle of the right-angle cutter is located on the extension line between the two chrome-plated metal rollers inside the guide assembly.

[0017] Furthermore, the stabilizing component includes two columns fixed to the upper end of the workbench, and two vertically distributed rubber rollers are rotatably connected between the two columns.

[0018] Furthermore, a base plate is fixed between the two vertical parts of the bracket, the base plate and the chrome-plated metal roller located below are on the same horizontal line, and a groove is opened at the upper end of the base plate, the ion air bar and the chrome-plated metal roller located above are on the same horizontal line.

[0019] Furthermore, the take-up shaft has threads on its outer circumference, and the take-up drum is threadedly connected to the threaded section of the take-up shaft, with a limit ring fixed at one end of the take-up drum.

[0020] Furthermore, each of the four corners of the bottom of the workbench is fixed with a support leg, and all the support legs are fixed together with a support plate. A through groove is opened in the workbench between the cutting assembly and the winding assembly, and a collection box is placed on the support plate below the through groove. An ear plate is fixed to the bottom of the workbench at one end of the through groove, and a waste roller is rotatably connected in the ear plate. The waste roller is located above the collection box.

[0021] This utility model has the following beneficial effects:

[0022] This invention solves the problem of static electricity interference during PE film cutting by setting up a guiding component, an anti-static component, and an unwinding component. The PE film master roll is placed in the unwinding component and unwound using the unwinding roller. It first passes between two chrome-plated metal rollers in one guiding component, is clamped and tightened, then passes under the ion air bar in the anti-static component, and finally is led out through two chrome-plated metal rollers in another guiding component. Throughout the process, because the PE film contacts the chrome-plated metal rollers, the static electricity can be discharged to the ground through the metal collar at the end of the chrome-plated metal roller and the grounding wire. At the same time, the ion air bar works in conjunction with the high voltage to generate a large number of positive and negative ions, which neutralize the static charge generated on the surface of the PE film due to friction. The ion air bar can generate a large number of air masses with positive and negative charges, which can neutralize the charge on the PE film in its ion radiation zone.

[0023] This invention solves the problem of not being able to select the cutting width according to the packaging product when cutting PE film into narrow rolls by setting a cutting component; during cutting, the threaded ring in the cutting component is rotated and moved outside the screw, thereby controlling the distance between two adjacent threaded rings, and thus controlling the width of the PE film after cutting. The PE film is cut by passing through the right-angle cutter under all the threaded rings, and the width of the PE film after cutting is the distance between the two right-angle cutters.

[0024] This invention solves the problems of burrs and fraying that easily occur when cutting PE film by setting up a cutting component, a winding component, and a worktable. The cut PE film is wound up by the winding shaft in the winding component. A corresponding winding drum is pre-threaded to the winding shaft. The PE film is placed outside the winding drum and is wound up as the winding shaft rotates. When the required winding degree is reached, the cylinder in the cutting component works, driving the hot melt cutter to descend and cut the PE film below. Because the hot melt cutter is used for the cutting operation, the PE film will not produce burrs and fraying after cutting, and the cut edge is smooth. It can be directly hot melt sealed, which facilitates the winding operation of bundles. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0038] Please see Figure 1-9 As shown, this utility model is an antistatic PE film cutting device, including an unwinding assembly 1, a guiding assembly 2, an antistatic assembly 3, a cutting assembly 4, a severing assembly 5, a rewinding assembly 6, and a worktable 7. The unwinding assembly 1, one guiding assembly 2, the antistatic assembly 3, another guiding assembly 2, the cutting assembly 4, the stabilizing assembly 8, the severing assembly 5, and the rewinding assembly 6 are arranged sequentially above the worktable 7 in the direction of PE film unwinding.

[0039] The PE film is unwound from the unwinding assembly 1 toward the winding assembly 6, and the PE film travels from the unwinding assembly 1 toward the winding assembly 6.

[0040] The unwinding assembly 1 includes two columns 101 fixed to the upper end of the workbench 7, and an unwinding roller 102 is rotatably connected between the two columns. The unwinding roller 102 is higher than the height of the chrome-plated metal roller 202, and a PE film master roll is wound around the unwinding roller 102.

[0041] The PE film master roll is placed outside the unwinding roller 102, which rotates between the two columns 101 to unwind and guide the PE film.

[0042] The guide assembly 2 includes two columns 201 fixed to the upper end of the worktable 7, and two chrome-plated metal rollers 202 distributed vertically are rotatably connected between the two columns 201.

[0043] Both ends of the two chrome-plated metal rollers 202 extend out of the second column 201, and a collar 203 is fitted on the same end of the two chrome-plated metal rollers 202 extending out of the second column 201. A grounding wire 2031 is fixedly connected to the bottom end of the collar 203, and the bottom end of the grounding wire 2031 is grounded.

[0044] As the PE film passes through the guide assembly 2, the two chrome-plated metal rollers 202 may rotate relative to each other under the action of friction. During this process, the static electricity that may be generated is transferred by the chrome-plated metal rollers 202 to the metal collar 203, and then conducted to the ground through the grounding wire under the collar 203 to remove the static electricity.

[0045] The static eliminator 3 includes two columns 301 fixed to the upper end of the workbench 7, and an ion air bar 302 is fixed between the two columns 301, with the outlet of the ion air bar 302 facing downward.

[0046] When the PE film passes through the antistatic component 3, the PE film passes under the ion bar 302. When the ion bar 302 is working, it generates a large number of positive and negative ions by passing high voltage electricity, which neutralizes the static charge generated on the surface of the PE film due to friction. The ion bar 302 can generate a large number of air masses with positive and negative charges, which can neutralize the charge on the PE film in its ion radiation zone and remove static electricity.

[0047] The cutting assembly 4 includes two columns 401 fixed to the upper end of the workbench 7, and a screw 402 is fixed between the two columns 401. The screw 402 is externally threaded with equally spaced threaded rings 403, and a right-angle cutter 404 is fixed at the bottom end of the threaded rings 403.

[0048] The blade of the right-angle cutter 404 faces the unwinding assembly 1, and the inner right angle of the right-angle cutter 404 is located on the extension line between the two chrome-plated metal rollers 202 inside the guide assembly 2.

[0049] During cutting, the threaded ring 403 in the rotating cutting assembly 4 moves outside the screw 402, thereby controlling the spacing between two adjacent threaded rings 403. As the PE film travels, the right-angle cutter 404 passing under all the threaded rings 403 is cut. The width of the PE film after cutting is the spacing between the two right-angle cutters 404. The cutting operation can be carried out as the PE film is unwound and travels, without the need for additional power.

[0050] The stabilizing component 8 includes two columns 801 fixed to the upper end of the worktable 7, and two vertically distributed rubber rollers 802 are rotatably connected between the two columns 801.

[0051] The cut PE film enters between two rubber rollers 802 in the stabilizing component 8 to prevent the cut PE film from becoming loose and to maintain the stability of subsequent winding. In addition, the rubber material of the rubber rollers 802 has high friction and more stable operation.

[0052] The cutting assembly 5 includes a bracket 501 fixed in an inverted U-shape on the workbench 7. A cylinder 502 is fixed to the top of the bracket 501. The piston rod at the telescopic end of the cylinder 502 passes through the horizontal part of the bracket 501 and is fixed with a hot melt cutter 503.

[0053] A base plate 504 is fixed between the two vertical parts of the bracket 501. The base plate 504 and the chrome-plated metal roller 202 located below are on the same horizontal line, and a groove 5041 is opened at the upper end of the base plate 504. The ion air bar 302 and the chrome-plated metal roller 202 located above are on the same horizontal line.

[0054] The cylinder 502 is installed using the bracket 501. When the required winding degree is reached, the cylinder 502 in the cutting assembly 5 works to drive the hot melt cutter 503 to descend and cut the PE film below. Because the hot melt cutter 503 is used for the cutting operation, the PE film will not produce burrs or frays after cutting, and the cut edge is smooth, allowing for direct hot melt sealing.

[0055] The take-up assembly 6 includes a vertical plate 601 fixed above the workbench 7. A take-up shaft 602 is rotatably connected to the side of the vertical plate 601, and take-up drums 603 are threadedly connected to the take-up shaft 602 at equal intervals. The take-up shaft 602 is threaded on its outer circumference, and the take-up drums 603 are threadedly connected to the threaded section of the take-up shaft 602. A limit ring 604 is fixed at one end of the take-up drums 603.

[0056] The take-up shaft 602 is installed using the upright plate 601. The corresponding take-up drum 603 is pre-threaded onto the take-up shaft 602. The PE film is placed outside the take-up drum 603 and is wound up as the take-up shaft 602 rotates. The limit ring 604 is set to prevent the PE film from shifting position during winding.

[0057] The workbench 7 has four fixed support legs 701 at the bottom corners, and a support plate 702 is fixed between all the support legs 701. A through groove 704 is opened in the workbench 7 between the cutting component 5 and the winding component 6, and a collection box 703 is placed on the support plate 702 below the through groove 704. An ear plate 705 is fixed at the bottom of the workbench 7 at one end of the through groove 704, and a waste roller 706 is rotatably connected in the ear plate 705. The waste roller 706 is located above the collection box 703.

[0058] All cutting operations are carried out above the workbench 7, which is supported by legs 701 and reinforced by support plates 702. Waste generated at the edge during cutting passes through the through groove 704 and is collected by the rotating waste roller 706. When a certain amount is collected, it can be cut off and placed in the collection box 703 for storage.

[0059] It should be noted that parts such as the take-up shaft 602, unwind roller 102, rubber roller 802, and waste roller 706 need to be connected to a drive structure (such as a motor) to drive the corresponding rollers or shafts to rotate, but for ease of demonstration, they are not shown in the attached drawings.

[0060] The specific working principle of this utility model is as follows: First, the PE film master roll is placed outside the unwinding roller 102, and the unwinding roller 102 is rotated between two columns 101 to unwind and lead out the PE film; then the PE film passes between two chrome-plated metal rollers 202 in one guide component 2, is clamped and tightened, then passes under the ion air bar 302 in the static elimination component 3, and finally is led out through two chrome-plated metal rollers 202 in another guide component 2. During this process, under the action of friction, the two chrome-plated metal rollers 202 may rotate relative to each other. The static electricity that may be generated during this process is transferred by the chrome-plated metal rollers 202 to the metal collar 203, and then conducted to the ground through the grounding wire under the collar 203 to remove static electricity. When the PE film passes under the ion air bar 302, the ion air bar 302 works, and high voltage is applied to generate a large number of positive and negative ions to neutralize the static charge generated on the surface of the PE film due to friction.

[0061] Subsequently, the PE film passes through the cutting assembly 4. As the PE film travels, it is cut by the right-angle cutter 404 passing under all the threaded rings 403. The width of the PE film after cutting is the distance between the two right-angle cutters 404. The cut PE film enters between the two rubber rollers 802 in the stabilizing assembly 8 to prevent the cut PE film from becoming loose. Finally, the corresponding take-up drum 603 is pre-threaded onto the take-up shaft 602, and the PE film is placed outside the take-up drum 603 and is wound up as the take-up shaft 602 rotates.

[0062] When the winding drum 603 reaches the required winding degree, the cylinder 502 in the cutting assembly 5 works, driving the hot melt cutter 503 to descend and cut the PE film below it; the waste generated at the edge during cutting passes through the through groove 704 and is wound and collected by the rotating waste roller 706. When a certain amount is collected, it can be cut off and placed in the collection box 703 for storage.

[0063] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
