Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette sorting and packaging equipment, in particular to a self-repairing and sharpening cutting knife safety device for completely biodegradable non-woven fabrics. Background Art
[0002] In tobacco logistics, due to the different needs of each retail merchant, it is necessary to sort the cigarette cartons for distribution. In order to facilitate distribution, the sorted cigarette cartons need to be packaged. The early packaging material used PE shrinkable film, which was later changed to non-woven fabrics. Because PE plastic film is non-degradable and causes environmental pollution, most non-woven fabrics contain chemical fiber components and can only be decomposed into particles that remain in the environment, which still does not meet the current policies and environmental protection requirements. Now, fully biodegradable non-woven fabrics made of plant fibers can be completely degraded into carbon dioxide and water, without residue or pollution, which fully meets the requirements of green environmental protection.
[0003] The cigarette packing machine wraps the cigarette pile with rolled fully biodegradable non-woven fabric. Since the length of the fully biodegradable non-woven fabric required for wrapping each cigarette pile is limited, the fully biodegradable non-woven fabric must be cut with a cutting knife after wrapping to form an independent cigarette package, which is convenient for wrapping the next cigarette pile.
[0004] The current cutting knife used for cutting fully biodegradable non-woven fabrics is a hot melt adhesive curing and fully biodegradable non-woven fabric cutting device disclosed in a Chinese patent with application number CN202321720437.3, which is arranged on a cigarette packing machine, including a table, which is fixed and horizontally arranged, and a slit is opened on the table; a cooling head, which is located above the table, and has a cooling medium channel inside the cooling head, so that the cooling head has a lower temperature when working, and the cooling head is connected to the head driving mechanism, so that the head is pressed against the table to perform a pressing action; and a cutting knife, which is located below the table and is connected to a cutting knife driving device, so that the cutting knife is facing the table and can pass through the slit of the table to cut the fully biodegradable non-woven fabric pressed on the table by the cooling head. The specific cutting knife and structural schematic diagram are shown as follows Figure 1 shown.
[0005] Although fully biodegradable nonwoven fabrics are very easy to cut, after several months of continuous use, the cutting edge of the cutting knife becomes blunt, and the cutting edges become tangled when the fully biodegradable nonwoven fabrics are cut, resulting in uneven cutting edges and unsightly cigarette packs.
[0006] In order to ensure the rigidity of the cutting knife, the cutting knife made of steel plate and with serrations is heavy. Due to the compact structure of the cigarette packing machine, it is not easy to disassemble and sharpen the cutting knife. In addition, due to the heavy cutting knife, the maintenance personnel may be easily injured or cut during the disassembly and assembly process. Therefore, a device is needed that can sharpen the cutting knife at any time without disassembly on the cigarette packing machine, so that the cutting knife can be used for a long time without disassembly, thereby avoiding injuries to the maintenance personnel during the maintenance process. Utility Model Content

[0033] In the following specific embodiments, a fully biodegradable non-woven fabric self-repairing cutting knife safety device of the utility model is installed on the frame of a cigarette packaging machine. Due to the self-repairing safety device, the cutting knife is changed from the original serrated blade to an ordinary blade with a beveled edge. The fully biodegradable non-woven fabric self-repairing cutting knife safety device of the utility model is located on one side or both sides of the cutting knife, depending on whether the cutting edge of the cutting knife is single-sided or double-sided. If it is single-sided, it is located on one side of the cutting edge surface, and if it is double-sided, it is installed on both sides. Embodiment 1
[0034] Please refer to Figure 2-Figure 5 According to one aspect of the present application, an embodiment provides a fully biodegradable nonwoven self-sharpening cutting knife safety device, comprising a linear slide module 1, a bracket 2, a sanding belt motor 3 and a sanding belt head 4, wherein the linear slide module 1 comprises a slide 11, a bracket 2 is mounted on the slide 11, and a sanding belt motor 3 is mounted on the bracket 2;
[0035] The knife sharpening sanding belt machine head 4 comprises a sanding belt machine head frame 41, a driving wheel 42, a driven wheel 43 and a sanding belt 47, wherein the driving wheel 42 is provided with a retaining ring, and driving wheels 42 and driven wheels 43 are respectively arranged at both ends of the sanding belt machine head frame 41, and the sanding belt 47 is wound around the driving wheel 42 and the driven wheel 43; a pad 44 is arranged on the sanding belt machine head frame 41, and the pad 44 is located between the driving wheel 42 and the driven wheel 43, and the pad 44 approaches the sanding belt 47 on the knife sharpening side from the inside to provide support during knife sharpening; a tensioning wheel 45 is arranged on the sanding belt machine head frame 41, and the tensioning wheel 45 supports the sanding belt 47 on the non-sharpening side to tension the sanding belt 47, and the tensioning wheel 45 is arranged on a leaf spring 46.
[0036] The sanding belt head frame 41 is installed on the bracket 2 at an adjustable angle, and the motor shaft of the sanding belt motor 3 is connected to the driving wheel 42 to drive the driving wheel 42 to rotate, thereby driving the sanding belt 47 to rotate;
[0037] The bracket 2 is provided with two air blowing pipes, which are connected to high-pressure air pipes. The air nozzles of the air blowing pipes are obliquely facing the sanding belt 47 on one side of the grinding knife from both sides of the sanding belt 47. During the grinding process, the grinding part is cooled by blowing air and waste chips are blown away at the same time.
[0038] The two ends of the linear slide module 1 are arranged on the frame of the cigarette packing machine, close to the position of the cutting knife 6, so that when the grinding belt head 4 is moved by the slide 11, the grinding belt 47 contacts the blade surface of the cutting knife 6 for grinding.
[0039] This embodiment has a disadvantage, that is, in actual use, after the cutting knife is ground once or twice, the abrasive belt cannot contact the blade surface of the cutting knife, and manual adjustment of the device or the cutting knife is required, which is relatively cumbersome. Embodiment 2
[0040] Please refer to Figure 6This embodiment is improved on the basis of the first embodiment, that is, a second linear slide 5 is arranged on the slide 11 of the linear slide module 1, a bracket 2 is arranged on the slide of the second linear slide 5, the sliding direction of the second linear slide 5 is perpendicular to the sliding direction of the linear slide module 11, and the second linear slide 5 is an electric slide.
[0041] In this embodiment, the installation surface of the slide 11 of the linear slide module 1 can be horizontal or vertical. If the movement direction of the slide 11 of the linear slide module 1 is forward and backward movement, then after the second linear slide 5 is installed on the slide 11 of the linear slide module 1, its movement direction is horizontal left and right movement, or vertical up and down movement. Since the cutting knife 6 is vertically arranged, its edge surface must be an inclined surface. Therefore, regardless of whether the second linear slide 5 moves left and right in the horizontal direction or moves up and down in the vertical direction, the cutting knife 6 can be effectively sharpened. And by adjusting the moving distance of the second linear slide 5, the disadvantages of the first embodiment can be avoided, and the cutting knife 6 can be effectively sharpened multiple times.
[0042] The utility model discloses a completely biodegradable nonwoven fabric self-repairing cutting knife safety device, which basically realizes the lifelong use of the cutting knife without replacement, and completely avoids the danger caused by the need to disassemble the cutting knife.
[0043] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of the present invention.
