Description

Technical Field

[0001] This patent relates to the field of tobacco processing equipment technology, specifically to a noise reduction device suitable for tobacco embossing machines. Background Technology

[0002] Embossing machines are mainly used for embossing, bubble pressing, wrinkling, and label pressing on various fabrics. They can also press labels onto non-woven fabrics, coated fabrics, artificial leather, paper, and aluminum plates, creating simulated leather patterns and various shades of designs. Ultrasonic embossing machines, also known as ultrasonic lace machines, are highly efficient sewing and embossing equipment. They are mainly used for hemming, welding, cutting, and embossing synthetic fiber fabrics. Processed products feature good water tightness, high production efficiency, no need for needles and threads, smooth welded surfaces without burrs, and a good hand feel. They are widely used in the clothing, toy, food, environmentally friendly non-woven bags, and mask industries.

[0003] Cigarette embossing machines differ slightly from ordinary embossing machines. They are specifically designed for embossing cigarette boxes and inner lining paper. In the tobacco processing industry, embossing cigarette inner lining paper is a crucial step in enhancing packaging quality and anti-counterfeiting features. However, traditional embossing equipment exhibits long-term noise pollution problems during high-speed operation. When the embossing rollers impact the paper thousands of times per minute, the collision of mechanical parts excites broadband vibration energy. This, combined with the meshing impact of the gear transmission chain and the whistling of pneumatic components during pressure relief, creates a composite noise peaking at 100 dB(A). This high-intensity sound wave diffuses through two paths: one is the mid-to-high frequency noise radiated directly into the air, and the other is the low-frequency vibration transmitted through the equipment base to the factory structure.

[0004] Existing passive noise reduction measures face a triple failure: simple soundproof covers, lacking a layered filling design, are insufficient for low-frequency noise insulation; the glass wool filling becomes brittle under the high-temperature conditions of the embossing machine, resulting in a decrease in sound absorption coefficient after three months; and traditional vibration damping pads, due to improper inherent frequency matching, amplify resonance. More seriously, embossing machine operation requires frequent contact with the workstation to clean paper scraps or adjust patterns, and the fully enclosed soundproofing structure severely reduces production efficiency. Such high-intensity noise has a serious impact on the health of employees working near the equipment for extended periods, leading to hearing damage, neurasthenia, and decreased work efficiency. Simultaneously, the structural characteristics of the embossing machine itself impose certain limitations on the design and installation of noise reduction devices, such as limited internal space and the need for frequent contact with the embossing parts by operators. These factors necessitate that the design of noise reduction devices fully consider compatibility with the embossing machine and ease of operation. Therefore, a noise reduction device that is both highly efficient in noise reduction and easy to operate, while also being compatible with the production flow of cigarette embossing machines, is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a noise reduction device suitable for tobacco embossing machines, in order to solve the problem mentioned in the background art that most existing embossing machines often generate a lot of noise during use, but most existing embossing machines are not equipped with noise reduction mechanisms, which has a certain impact on the health of workers and is inconvenient to use.

[0006] Firstly, a noise reduction device suitable for a tobacco embossing machine is provided. The noise reduction device includes a moving mechanism and a sound insulation mechanism. The moving mechanism provides a moving path for the sound insulation mechanism, allowing the sound insulation mechanism to move on the moving mechanism. The sound insulation mechanism completely or partially encloses the tobacco embossing machine within the sound insulation mechanism. The tobacco embossing machine is relatively fixed, and the moving mechanism is fixedly installed on both sides of the tobacco embossing machine. The sound insulation mechanism is placed on the moving mechanism and performs reciprocating lateral movements along the moving mechanism. When the tobacco embossing machine needs the noise reduction device to reduce noise, the sound insulation mechanism moves laterally along the moving mechanism towards the tobacco embossing machine. When the tobacco embossing machine does not need the noise reduction device, the sound insulation mechanism moves laterally along the moving mechanism away from the tobacco embossing machine.

[0007] Furthermore, the sound insulation mechanism includes a soundproof cover, which may be a hollow structure or a non-hollow structure, with the non-hollow structure filled with sound-absorbing material.

[0008] Furthermore, sound-absorbing materials include porous sound-absorbing materials, flexible sound-absorbing materials, natural fibers, and / or sound insulation felt.

[0009] Furthermore, the soundproof enclosure is made of lightweight materials, including aluminum alloy, magnesium alloy, titanium alloy, stainless steel, fiberglass, and engineering plastics.

[0010] Furthermore, the shape of the side of the soundproof enclosure is one of the following: "7", inverted "U", inverted "L", inverted "U", doorway, frame, arch, flag, cylinder, tunnel, corridor, or cane.

[0011] Furthermore, the sound insulation mechanism also includes a sound insulation panel and a flipping component. The sound insulation panel is movably fixed to the sound insulation cover via the flipping component. When the sound insulation cover moves laterally, the sound insulation panel flips upward via the flipping component. When the sound insulation cover returns to its original position, the sound insulation panel flips downward via the flipping component.

[0012] Furthermore, the sound insulation mechanism moves in one of the following ways on the moving mechanism: rolling, sliding, biting, or locking.

[0013] Furthermore, the moving mechanism includes a first guide rail, a second guide rail, and a moving component, which is fixed to the bottom of the sound insulation mechanism to support the lateral displacement of the moving component on the first and second guide rails.

[0014] Furthermore, the first guide rail and the second guide rail are arranged in parallel on both sides of the tobacco embossing machine.

[0015] Furthermore, the moving component is selected from rollers, sliders, gears, balls, latches, guide blocks, or dampers.

[0016] This patent has the following beneficial effects:

[0017] 1. This patent provides a noise reduction device suitable for tobacco embossing machines, including a moving mechanism and a sound insulation mechanism. The sound insulation cover in the sound insulation mechanism has a double-layer shell structure, which effectively isolates some noise. In addition, the double-layer shell is filled with sound-absorbing material to further block the noise diffusion, effectively heat dissipating and reducing noise from the noise source of the tobacco embossing machine.

[0018] 2. The shape of the soundproof cover in this patent is based on the production line of the cigarette embossing machine. The cover has a cavity to accommodate the passage of the cigarette embossing machine, so that the soundproof cover can be directly taken out by the moving mechanism without repeated installation, thus optimizing the usage process.

[0019] 3. The embossing noise reduction device of this patent can reduce the noise generated by the embossing machine from the original 100 decibels to below 80 decibels, which significantly improves the noise situation of the working environment, effectively protects the health of operators, and also helps to improve production efficiency and equipment operation stability.

[0069] Example 1

[0070] A noise reduction device suitable for tobacco embossing machines, please refer to... Figure 1 The noise reduction device includes a moving mechanism 100 and a sound insulation mechanism 200. The moving mechanism 100 provides a moving path for the sound insulation mechanism 200, allowing the sound insulation mechanism 200 to move on the moving mechanism 100. The sound insulation mechanism 200 completely or partially encloses the tobacco embossing machine in the sound insulation mechanism 200. The tobacco embossing machine is relatively fixed, and the moving mechanism 100 is fixedly installed on both sides of the tobacco embossing machine. The sound insulation mechanism 200 is placed on the moving mechanism 100 and moves back and forth laterally along the moving mechanism 100.

[0071] Please refer to Figures 2-5 The moving mechanism 100 includes a first guide rail 110, a second guide rail 120, and a moving component 130. The first guide rail 110 and the second guide rail 120 are two long rod-shaped structures of the same length, and the first guide rail 110 and the second guide rail 120 are arranged parallel to each other on both sides of the tobacco embossing machine.

[0072] It should be noted that the cigarette embossing machine has an approximate rectangular structure. In this patent, "both sides of the cigarette embossing machine" specifically refers to the sides of the two long sides of the cigarette embossing machine.

[0073] Specifically, the movable component 130 is fixed to the bottom of the sound insulation mechanism 200 to support the lateral displacement of the movable component 130 on the first guide rail 110 and the second guide rail 120. The materials of the first guide rail 110 and the second guide rail 120 include metals or alloys with high rigidity, good compressive strength and not easy to deform.

[0074] Specifically, the sound insulation mechanism 200 moves on the moving mechanism 100 in one of the following ways: rolling, sliding, biting, or locking; the moving component 130 is selected from one of the following: roller, slider, gear, ball, buckle, guide block, or damping, but this patent is not limited to this.

[0075] The sound insulation mechanism 200 includes a sound insulation cover 210, a sound insulation panel 220, and a flipping component 230. The sound insulation panel 220 is movably fixed to the sound insulation cover 210 via the flipping component 230. When the sound insulation cover 210 moves laterally, the sound insulation panel 220 flips upward via the flipping component 230. When the sound insulation cover 210 returns to its original position, the sound insulation panel 220 flips downward via the flipping component 230.

[0076] Specifically, the soundproof panel 220 is disposed on the side of the soundproof cover 210 perpendicular to the first guide rail 110 and the second guide rail 120. The soundproof panel 220 can be square in shape and its size can just cover the side of the soundproof cover 210.

[0077] The flipping component 230 can be used to movably fix the sound insulation plate 220 to the sound insulation cover 210 by means of hinges, magnets, buckles, or bearings, but this patent is not limited thereto.

[0078] Specifically, the shape of the side of the soundproof cover 210 is one of the following: "7", inverted "U", inverted "L", inverted "U", doorway, frame, arch, flag, cylinder, tunnel, corridor, or cane. This patent is not limited to this specific shape.

[0079] It should be noted that the soundproof cover 210 allows the tobacco embossing machine to be partially or completely surrounded by the soundproof cover 210 to reduce noise. However, there should be a uniform cavity on the side along the direction of the first guide rail 110 and the second guide rail 120 to accommodate the tobacco embossing machine, and there are no restrictions on the curvature or shape of the cover wall surrounding the tobacco embossing machine.

[0080] Specifically, the soundproof cover 210 is made of lightweight material, which is one of aluminum alloy, magnesium alloy, titanium alloy, stainless steel, fiberglass, and engineering plastic. This patent is not limited to this type.

[0081] Aluminum alloys are low-density, easy to process, and have good corrosion resistance. The preferred grades are 5052, 6061, 6063, and 7075, and these alloys have undergone surface treatments such as anodizing and spraying. Magnesium alloys are the lowest density and have good shock absorption among engineering metals. The preferred grades are AZ31B and AZ91D. Titanium alloys are commonly used in extreme environments in aerospace and chemical industries. They have extremely high strength and the best corrosion resistance and high-temperature resistance; however, their cost and processing difficulty also increase accordingly. Stainless steel is the most commonly used engineering metal in daily life. Considering corrosion resistance, strength, formability, cost, and service life, it is the best material. The preferred grades are austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel.

[0082] Engineering plastics commonly used in industrial housings include polycarbonate, acrylonitrile-butadiene-styrene copolymer, glass fiber reinforced plastic, polypropylene, polyvinyl chloride, and polymethyl methacrylate, which combine the advantages of high transparency and corrosion resistance.

[0083] Specifically, the soundproof cover 210 can be a hollow structure or a non-hollow structure, with the non-hollow structure filled with sound-absorbing material.

[0084] Sound-absorbing materials include porous sound-absorbing materials, flexible sound-absorbing materials and / or natural fibers, but this patent is not limited to these.

[0085] The function of sound-absorbing materials is to convert the sound energy passing through the soundproof cover 210 into heat energy and dissipate it. They usually have high sound absorption coefficient, flame retardancy and environmental protection, and are not easy to settle or pulverize or heat resistant.

[0086] Specifically, porous sound-absorbing materials absorb sound energy by relying on the friction and viscosity loss of sound waves within the tiny pores of the material. Porous sound-absorbing materials include mineral wool, rock wool, glass wool, centrifugal glass wool, polyester fiber wool, melamine foam, and polyurethane foam. Among these, mineral wool, rock wool, glass wool, centrifugal glass wool, and melamine foam have the best sound absorption effect in the mid-to-high frequency band.

[0087] Specifically, flexible sound-absorbing materials include asphalt damping felt and butyl rubber damping felt. They reduce radiated noise by utilizing high damping characteristics and make a significant contribution to sound insulation. Their sound absorption coefficient is relatively low compared to porous materials, so they are often used in combination with porous materials.

[0088] Specifically, the renewable and biodegradable characteristics of natural fibers can replace some porous sound-absorbing materials. Sound energy is converted into heat energy due to friction and viscous resistance as sound waves propagate through the intricate fiber structure and pores within the material. Natural fibers include cotton, wool, flax, jute, coconut fiber, sisal, kapok, bamboo, hemp, reed, and wheat straw.

[0089] Specifically, in this embodiment, the side of the soundproof cover 210 is shaped like an inverted "L". The soundproof cover 210 includes a first surface 211, a second surface 212, a third surface 213, a fourth surface 214, a fifth surface 215, a sixth surface 216, a seventh surface 217, and an eighth surface 218 made of stainless steel. The first surface 211, the second surface 212, the third surface 213, the fourth surface 214, the fifth surface 215, and the sixth surface 216 are rectangles of different sizes, while the seventh surface 217 and the eighth surface 218 are inverted "L" shaped surfaces of the same size as the side of the soundproof cover 210.

[0090] The thickness of the first surface 211, the second surface 212, the third surface 213, the fourth surface 214, the fifth surface 215, the sixth surface 216, the seventh surface 217, and the eighth surface 218 of the soundproof cover is 2mm, and the length of the side of the soundproof cover is 42.5mm.

[0091] The first surface 211 of the soundproof enclosure is the top surface of the soundproof enclosure 210. The third surface 213 and the fifth surface 215 of the soundproof enclosure are located on the bottom surface of the soundproof enclosure 210, and the size of the first surface 211 is equal to the combined size of the third surface 213 and the fifth surface 215. The second surface 212 of the soundproof enclosure is the rear of the soundproof enclosure 210. The fourth surface 214 and the sixth surface 216 of the soundproof enclosure are located in front of the soundproof enclosure 210, and the size of the second surface 212 is equal to the combined size of the fourth surface 214 and the sixth surface 216. The eighth surface 218 of the soundproof enclosure is covered by the soundproof panel 220 that is not flipped up.

[0092] The movable component 130 includes a first movable member 131, a second movable member 132, a third movable member 133, and a fourth movable member 134. The first movable member 131 and the second movable member 132 are fixed to the side where the sixth surface 216 and the fifth surface 215 of the soundproof cover intersect. The first movable member 131 and the second movable member 132 are arranged on the first guide rail 110 in the opposite direction to the fixed end. The third movable member 133 and the fourth movable member 134 are fixed to the third surface 213 of the soundproof cover. The third movable member 133 and the fourth movable member 134 are arranged on the second guide rail 120 in the opposite direction to the fixed end.

[0093] Specifically, the moving component 130 is a roller, the first guide rail 110 and the second guide rail 120 are slide rails, and the sound insulation mechanism 200 moves on the moving mechanism 100 by rolling.

[0094] The soundproof cover 210 shown in this embodiment has a non-hollow structure and is uniformly filled with sound-absorbing cotton. The sound-absorbing cotton is made of 100% polyester fiber, which is hot-pressed with high technology and formed into a cocoon shape. The soundproof cover 210 shown in this embodiment can reduce the noise generated by the tobacco embossing machine from the original 100 decibels to below 80 decibels, which significantly improves the noise situation of the working environment, effectively protects the health of the operators, and also helps to improve production efficiency and equipment operation stability.

[0095] When the embossing roller of the tobacco embossing machine needs a noise reduction device to reduce noise, the sound insulation plate 220 is flipped up, and the sound insulation cover 210 is pushed to move laterally along the first guide rail 110 and the second guide rail 120 toward the tobacco embossing machine; when the embossing roller of the tobacco embossing machine does not need a noise reduction device, the sound insulation cover 210 is pushed to move laterally along the first guide rail 110 and the second guide rail 120 away from the tobacco embossing machine. After the sound insulation cover 210 returns to its initial position, the flipped-up sound insulation plate 220 is lowered.

[0096] Example 2

[0097] The difference between this embodiment and the noise reduction device in Embodiment 1 is the shape of the soundproof cover 210, and it further demonstrates the way the noise reduction device is used in conjunction with the tobacco embossing machine.

[0098] Please refer to Figures 6a-7e The soundproof cover 210 is an inverted "U" shaped structure welded from stainless steel plates. Sound-absorbing cotton is filled between the steel plates. The bottom of the soundproof cover 210 is on the same horizontal line so that the first guide rail 110 and the second guide rail 120 are parallel to each other and fixed at the same height on both sides of the cigarette embossing machine. The moving component 130 at the bottom of the soundproof cover 210 is a roller, which allows the soundproof cover 210 to move laterally along the first guide rail 110 and the second guide rail 120.
