Description

Technical Field

[0001] This utility model belongs to the technical field of packaging bag processing equipment, and in particular relates to a cutting device for processing environmentally friendly tea packaging bags. Background Technology

[0002] Drinking tea has numerous benefits. Modern scientific analysis has identified over 450 organic chemical components and over 40 inorganic mineral elements in tea. These components contain many nutrients and medicinal properties. The main organic chemical components include: tea polyphenols, alkaloids, proteins, amino acids, vitamins, pectin, organic acids, polysaccharides, sugars, enzymes, and pigments. The main inorganic mineral elements include: potassium, calcium, magnesium, cobalt, iron, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, and selenium. Tea not only has therapeutic effects on many diseases but also promotes longevity and has anti-aging properties.

[0003] Existing tea packaging bags generally have inner and outer bags, and some of these tea packaging bags are beginning to be made using biodegradable plastics. Biodegradable plastics are a new type of polymer material, commonly including polylactic acid (PLA), polybutylene succinate (PBS), and polybutylene adipate / terephthalate (PBA). These materials can gradually decompose in the natural environment through the action of microorganisms, eventually transforming into harmless substances with minimal environmental impact.

[0004] Environmentally friendly tea packaging bags made from biodegradable plastic are processed similarly to other ordinary plastic packaging bags. Typically, two layers of film are heat-sealed at the edges, and then a cutting device is used to cut the continuous film material into individual bag-like structures to meet the needs of tea packaging. Most existing cutting devices use a single blade, with a punching mechanism connected to the top of the blade performing the downward cutting action. This method requires a step-by-step unwinding mechanism, meaning the continuous strip of film is fed intermittently. The feeding interval is to match the cutting operation. This method results in a single feeding channel and alternating feeding and cutting, wasting a lot of time and affecting cutting efficiency. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figures 1 to 8 As shown, this embodiment discloses a cutting device for processing environmentally friendly tea packaging bags, which solves the problems of low efficiency and poor cutting quality caused by the single feeding channel, alternating material feeding and cutting in existing cutting devices. Through innovative structural design, continuous and efficient cutting of film material a is achieved, improving production efficiency, ensuring cutting quality, and meeting the needs of large-scale production of environmentally friendly tea packaging bags.

[0032] The cutting device for processing environmentally friendly tea packaging bags mainly includes a frame 100, a worktable 110, a movable groove 120, a lifting base 130, a base spring 140, a cutting roller 200, a cutting head 300, and a pressure roller 400.

[0033] The frame 100 serves as the supporting structure for the entire device, providing a mounting base for other components. The frame 100 is assembled from aluminum alloy profiles and, together with the panel, forms the frame structure. A horizontal worktable 110 is located at the top of the frame 100 to accommodate the film material a to be cut. Figure 2 As shown, the frame 100 has a movable groove 120 near the front. The top of the movable groove 120 is an open structure located on the worktable 110. A lifting base 130 is movably connected within the movable groove 120, and a base spring 140 is provided at the bottom of the lifting base 130. The function of the base spring 140 is to provide elastic support for the lifting base 130, allowing it to move downwards under the pressure of the cutting roller 200 and automatically return to its original position after cutting. Under normal conditions, the top of the lifting base 130 is flush with the worktable 110. When the cutting roller 200 cuts the film material a, the lifting base 130 correspondingly and appropriately lowers.

[0034] A cutting roller 200 is positioned directly above the lifting base 130, and several cutting heads 300 are mounted on the cutting roller 200. The cutting heads 300 and the lifting base 130 together form the cutting structure for the environmentally friendly tea packaging bag film a. When the cutting roller 200 rotates, the cutting heads 300 come into contact with the film a on the lifting base 130, thus performing the cutting action.

[0035] Specifically, in combination Figure 3 As shown, in this embodiment, there are 8 cutting heads 300, which are sequentially attached and distributed. The installation angles of each cutting head 300 are staggered in sequence, which allows each cutting head 300 to complete the cutting action one by one in sequence during the rotation of the cutting roller 200.

[0036] like Figure 4 As shown, the cutting roller 200 includes a rotating shaft 210, the axial central region of which is the mounting area for the cutting head 300. Locking blocks 220 are threaded to both ends of the mounting area to fix the position of the cutting head 300 and prevent it from loosening during rotation. The rotating shaft 210 within the mounting area has eight centrally symmetrical protrusions 211, such as... Figure 5 As shown.

[0037] like Figure 6As shown, the cutting head 300 includes a main body 310 with a circular outer contour, and a boss 330 is provided on one side of the outer periphery of the main body 310. The outer surface of the boss 330 is an arc surface structure, and the inner end of the arc surface is tangent to the outer side wall of the main body 310, that is, the outer contour line of the cutting head 300 has a logarithmic spiral structure. This design allows the cutting head 300 to contact the film material a more smoothly during rotation and gradually increases the holding strength before cutting, which can improve cutting stability. A mounting hole 320 is provided at the center of the main body 310 of the cutting head 300, and a groove 321 adapted to the outer contour of the protruding edge 211 is provided in the mounting hole 320. The cutting head 300 uses the groove 321 and the protruding edge 211 to form an angle positioning structure, and the mounting angles of adjacent cutting heads 300 are staggered. This design allows different cutting heads 300 to cut the film material a from different angles, which improves cutting efficiency and quality when done synchronously on the same cutting roller 200, while also increasing the installation stability and reliability of the cutting heads 300.

[0038] The outer end of the boss 330 is movably connected to a limiting seat 340, and a blade 350 is movably connected within the limiting seat 340. A cutting spring 380 abuts against the blade 350 and the limiting seat 340, allowing the blade 350 to slide radially inward and outward along the main body 310. The function of the cutting spring 380 is to provide a certain pressure to the blade 350, enabling it to maintain a stable cutting force when cutting the film material a. Simultaneously, when the blade 350 encounters hard impurities or uneven thickness of the film material a, it can automatically retract, preventing damage to the blade 350 and extending its service life.

[0039] Specifically, in combination Figure 7 and Figure 8 As shown, the limiting seat 340 has an internal mounting groove, which forms an opening at its outer end. A blade holder 360 is connected to the inner end of the blade 350, and the blade holder 360 is movably inserted into the mounting groove. A movable plate 370 is connected to the inner end of the blade holder 360, and a cutting spring 380 abuts against the bottom of the mounting groove at the inner end of the movable plate 370. The cutting edge of the blade 350 faces outward and extends beyond the mounting groove, facilitating contact with the film material a for cutting. It should be noted that a travel limiting structure is provided between the blade holder 360 and the limiting seat 340. Specifically, the blade holder 360 has bosses 330 on both sides of the mounting groove opening. The travel limiting structure restricts the sliding stroke of the blade 350, preventing it from overextending or retracting under the action of the cutting spring 380, ensuring accurate cutting position of the blade 350, and preventing collision or detachment between the blade 350 and the limiting seat 340, thus improving the safety and reliability of the device.

[0040] like Figure 2As shown, a pressure roller 400 is located on one side of the cutting roller 200 on the frame 100. The pressure roller 400 and the cutting roller 200 are synchronously connected to a rotary drive component via a transmission chain. The function of the pressure roller 400 is to stably control the forward feeding of the film material a and to press down the film material a during the cutting process, preventing the film material a from moving or deforming under the cutting force, thus ensuring the accuracy and quality of the cutting. The pressure roller 400 and the cutting roller 200 cooperate to form a stable cutting system.

[0041] A material collection trough 150 is provided on the front side of the frame 100, and the top of the material collection trough 150 is open. The function of the material collection trough 150 is to collect the finished product b that falls off after cutting, so as to facilitate centralized processing.

[0042] A drive housing 160 is located on one side of the frame 100. The rotary drive component includes a geared motor housed within the drive housing 160. The geared motor converts the high-speed rotational power into low-speed, high-torque power through a reduction gear, meeting the rotational requirements of the cutting roller 200 and the pressure roller 400. The drive housing 160 protects the rotary drive component from external environmental influences and facilitates equipment maintenance and management.

[0043] In the specific implementation process, the external unwinding mechanism feeds the rolled film material a at a threshold speed. After passing the rear end of the worktable 110, it passes through the gap between the pressure roller 400 and the worktable 110. The pressure roller 400 stabilizes the film material a. The end of the film material a passes through the bottom of the cutting roller 200 from back to front. When the cutting roller 200 rotates and the blade 350 rotates to the bottom position, it can work with the lifting base 130 to cut the film material a. The outer diameter of the cutting head 300 is matched with the pre-heat-sealed structure on the film material a, so that the film material a forms bag-shaped finished products b after cutting. The finished products b fall into the collection trough 150 to wait for stacking and packaging.

[0044] In other embodiments, the top of the lifting base 130 is also provided with anti-slip texture. The function of the anti-slip texture is to increase the friction between the lifting base 130 and the membrane material a, prevent the membrane material a from sliding during the cutting process, and ensure the accuracy and quality of the cutting.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
