Technical Field
[0001] This utility model belongs to the technical field of packaging bag processing equipment, and in particular relates to an environmentally friendly tea packaging bag cutting device. Background Technology
[0002] China's tea culture is profound and extensive, and drinking tea has been a hobby for many Chinese people since ancient times.
[0003] There are various existing tea packaging styles. One type of tea packaging involves placing multiple sealed small bags of the same size into a metal box, with each small bag containing a smaller bag of tea leaves. This allows for one-bag-at-a-time consumption, preventing the tea from becoming damp and yellowing after opening, which can affect its taste, unlike traditional boxed tea. In recent years, with the increasing global awareness of environmental protection, environmental protection concepts have been widely promoted and applied in various fields, including the tea packaging industry. To respond to environmental calls and reduce plastic pollution, some tea packaging bags have begun 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. The processing method for environmentally friendly tea packaging bags made of biodegradable plastics is similar to that of other ordinary plastic packaging bags. Typically, two layers of film are heat-sealed at the edges, and then a slitting device is used to cut the continuous film into individual bag-like structures to meet the needs of tea packaging.
[0004] However, with the continuous development and evolution of the tea market, packaging bags are becoming increasingly diverse in structure to enhance their aesthetic appeal. This is especially true for tea products incorporating environmental protection concepts. In addition to using biodegradable plastic bags, the appearance of these bags is specifically designed, with some featuring irregular shapes such as leaves or fans. These shapes cannot be directly cut using traditional slitting devices. Traditional slitting devices can only cut long strips of film horizontally, resulting in rectangular bags. In other words, traditional slitting devices only have a single cutting function and cannot collect the leftover scraps after irregular cutting. Furthermore, these scraps are scattered haphazardly in the work area, wasting raw materials, increasing production costs, polluting the work environment, and making cleanup cumbersome, thus reducing production efficiency. Therefore, to achieve the normal production of irregularly shaped environmentally friendly tea packaging bags, it is urgent to develop a new type of slitting device to solve the aforementioned problems of traditional equipment.

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.

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 Figure 1 As shown in the figure, this embodiment discloses an environmentally friendly tea packaging bag cutting device. This device can effectively solve the problems of traditional cutting devices being unable to accurately cut irregularly shaped tea packaging bags and being unable to centrally process scraps. It can achieve efficient and accurate cutting of irregularly shaped tea packaging bags made of environmentally friendly materials such as biodegradable plastics, and automatically collect the scraps generated during the cutting process, thereby improving production efficiency, reducing production costs, and meeting the market's demand for diversified and personalized environmentally friendly tea packaging.
[0032] The environmentally friendly tea packaging bag cutting device in this embodiment specifically includes a frame 100, a worktable 110, a sliding base 120, a cutting component 500, an unwinding component 200, a winding roller 600, and a guide roller 400. These components cooperate to complete the cutting operation of the environmentally friendly tea packaging bags.
[0033] The frame 100 is assembled from aluminum alloy profiles, with storage cabinets on both sides and height-adjustable feet at the bottom. Frame 100 serves as the supporting framework for the entire device, providing a stable mounting base for other components and ensuring the stability and reliability of the device during operation. A horizontal worktable 110 is located on top of the frame 100, providing a flat working surface for film feeding and slitting operations.
[0034] Furthermore, combined Figure 2 As shown, a sliding base 120 capable of horizontally moving back and forth is provided at the center of the workbench 110. The sliding base 120 achieves horizontal back and forth movement through a linear guide rail. In other embodiments, it can also achieve the same effect using a structure such as a lead screw and nut pair. Its main function in sliding back and forth is to facilitate the operator's external pulling and picking of materials during the cutting process or to cooperate with an external transfer mechanism for material discharge and transfer.
[0035] A cutting assembly 500 is located directly above the sliding base 120. The cutting assembly 500 is the core component of the entire device, used to complete the cutting action of the packaging bags. The cutting assembly 500 has a longitudinally movable punching block 510. The punching block 510 can move downwards, cooperating with the sliding base 120 to punch and cut the film material. Specifically, a mounting base 520 is connected to the top of the punching block 510, and a linear drive device (such as a pneumatic cylinder or hydraulic cylinder) is connected to the top of the mounting base 520. In this example, an electric telescopic cylinder is used. The linear drive device provides the power for the longitudinal movement of the punching block 510, enabling the punching block 510 to move downwards at a predetermined speed and stroke, completing the punching and cutting action of the film material.
[0036] Furthermore, in combination Figure 7 and Figure 8 As shown, the bottom of the stamping block 510 is provided with a cutter 511 corresponding to the shape outline of the packaging bag (in this embodiment, it is a horseshoe-shaped structure), with the cutting edge of the cutter 511 facing downwards. The shape of the cutter 511 is customized according to the irregular shape outline of the tea packaging bag, and it can accurately cut the film material into the required shape according to the design requirements.
[0037] The stamping block 510 is equipped with an inner pressure strip 512 and an outer pressure strip 513 on the inner and outer sides of the cutter 511, respectively. A buffer spring 514 is provided between the top of the inner pressure strip 512 and the outer pressure strip 513 and the stamping block 510. During the downward movement of the stamping block 510, the inner pressure strip 512 and the outer pressure strip 513 first abut against the top surface of the sliding base 120 to pre-compress the membrane material, preventing it from moving or deforming during the cutting process. As the stamping block 510 continues to move downward, the buffer spring 514 is compressed to its threshold strength. Because the inner pressure strip 512 and the outer pressure strip 513 can continue to compress the buffer spring 514 to keep its height position relatively stationary, and the cutter 511 is fixedly connected to the stamping block 510 and does not have a buffering effect, in this case, the cutting edge of the cutter 511 can extend below the inner pressure strip 512 and the outer pressure strip 513 to perform the final cut on the membrane material. This design, through the action of the buffer spring 514, achieves progressive compression and cutting of the membrane material, ensuring cutting quality, while avoiding hard collisions between the cutter 511 and the sliding base 120, thus extending the service life of the equipment.
[0038] Furthermore, to enrich the functionality of the slitting machine, an electric heating element 516 is installed inside the inner pressure strip 512. Specifically, this is an electric heating wire with a temperature control module, and a heat-dissipating plate 517 is connected to the heating end at the bottom of the electric heating element 516. The electric heating element 516 generates heat and distributes it evenly to the bottom surface of the inner pressure strip 512 through the heat-dissipating plate 517. During film cutting, the high temperature at the bottom of the inner pressure strip 512 softens the heat-sealing portion of the film, making the heat seal more secure and improving the sealing performance of the packaging bag. It should be noted that during actual operation, an appropriate heating temperature, such as 80°C or 110°C, should be set according to the material characteristics of the environmentally friendly film.
[0039] The bottom of the heat-equalizing plate 517 and the bottom of the outer pressure strip 513 are provided with an anti-stick layer 515 (such as a Teflon coating). The anti-stick layer 515 can prevent the film material from adhering to the inner pressure strip 512 or the outer pressure strip 513 during the cutting process, ensuring that the cut packaging bag can be easily removed, and avoiding the impact on production efficiency and product quality due to adhesion.
[0040] Correspondingly, the top of the sliding base 120 is provided with flanged support plates 121 on both sides of the slitting station. The function of the support plates 121 is to provide support and positioning for the edge of the membrane material during the feeding and cutting process, prevent the edge of the membrane material from sagging or deviating, ensure that the membrane material remains flat and stable during the slitting process, and further improve the accuracy of slitting.
[0041] Combined again Figure 1 and Figure 2 As shown, the cutting assembly 500 has an unwinding assembly 200 and a take-up roller 600 on its left and right sides, respectively. The unwinding assembly 200 includes at least two staggered unwinding rollers, which are used to hold the environmentally friendly film material to be processed. By setting multiple unwinding rollers, different specifications or materials of film materials can be combined to meet diverse packaging needs. The take-up roller 600 is used to collect the slitting waste of the environmentally friendly film material, orderly winding up the scraps generated during the slitting process for easy subsequent processing and recycling. Several guide rollers 400 are provided between the unwinding roller and the take-up roller 600. The film material passes through the unwinding roller, guide roller 400, and take-up roller 600 to form a material path, which passes through the slitting station of the stamping block 510. The function of the guide rollers 400 is to guide the film material to run smoothly along a predetermined path, ensuring that the film material remains taut during the slitting process and avoiding wrinkles or deviations that would affect the slitting quality. The unwinding roller and / or take-up roller 600 are driven by a stepping rotary drive device. This device precisely controls the rotation angle and speed of the unwinding and take-up rollers 600, enabling step-by-step feeding of the film material. This step-by-step feeding method allows the film material to stop after each fixed step, providing a stable cutting opportunity for the cutting assembly 500 and ensuring accurate and consistent slitting dimensions for each packaging bag.
[0042] In this embodiment, the unwinding assembly includes a first unwinding roller 210 and a second unwinding roller 220 that are longitudinally spaced apart. The first unwinding roller 210 and the second unwinding roller 220 are connected to the rear top end of the frame 100 via a bracket. This staggered unwinding roller structure allows the film materials on different unwinding rollers to be easily combined and stacked in subsequent processes, providing convenience for the production of multi-layered packaging bags.
[0043] A control roller 300 is pivotally mounted below the unwinding assembly. The environmentally friendly membrane material output from the first unwinding roller 210 and the second unwinding roller 220 is stacked on the outer wall of the control roller 300 to form a double-layer membrane material. The function of the control roller 300 is to provide initial control and guidance for the stacked double-layer membrane material, ensuring that the membrane material remains flat and stable during the feeding process.
[0044] like Figure 3 As shown, a control roller 300 is located on one side of the environmentally friendly membrane material feeding path, and a control pressure plate 310 is also provided. The control pressure plate 310 is connected to a linear drive device (such as a cylinder). In this embodiment, a cylinder is used, with its main body fixed on a support, and its telescopic rod connected to the control pressure plate 310. The control pressure plate 310 can move away from or towards the control roller 300 under the action of the cylinder, forming an intermittent clamping structure for the double-layer membrane material. When it is necessary to position the membrane material or pause the feeding, the control pressure plate 310 moves closer to the control roller 300, clamping the double-layer membrane material and preventing it from moving further. When it is necessary to resume feeding, the control pressure plate 310 moves away from the control roller 300, releasing the membrane material so that it can continue to run along the feeding path. This intermittent clamping structure can precisely control the timing and position of the membrane material feeding, providing a guarantee for subsequent precise cutting.
[0045] Furthermore, in combination Figure 4 The control roller 300 includes a rotating shaft 301, with a buffer sleeve 302 surrounding the rotating shaft 301. A covering sleeve 304 is attached to the outer wall of the buffer sleeve 302. One axial end of the rotating shaft 301 is pivotally connected to a support, allowing the control roller 300 to rotate freely on the support. The buffer sleeve 302 is made of an elastic material and has several axially perforated flexible holes 303. In this embodiment, the buffer sleeve 302 is made of PU. This structural design gives the buffer sleeve 302 a certain degree of elasticity and flexibility. When the control plate 310 presses the control roller 300, the buffer sleeve 302 can undergo elastic deformation, forming an elastic holding structure in conjunction with the pressing action of the control plate 310. The elastic holding structure can ensure effective clamping of the film material while avoiding damage to the film material due to excessive clamping force, ensuring the integrity and quality of the film material.
[0046] The outer wall of the wrapping sleeve 304 is provided with a first anti-slip texture 305. The first anti-slip texture 305 can increase the friction between the wrapping sleeve 304 and the membrane material, prevent the membrane material from sliding during the feeding process, and further improve the stability and accuracy of the membrane material feeding.
[0047] like Figure 5 As shown, the control plate 310 has a concave curved surface on the side near the control roller 300, and the inner contour of the concave curved surface matches the outer contour of the control roller 300. This design allows the control plate 310 to fit tightly against the surface of the control roller 300 when clamping the film material, increasing the contact area and improving the clamping effect. A second anti-slip texture 311 is provided on the concave curved surface, which further enhances the friction between the control plate 310 and the film material, ensuring that the film material will not slip during clamping and guaranteeing the accuracy of film material positioning.
[0048] It should be noted that the top of the sliding base 120 has flanged support plates 121 on both sides of the slitting station. The function of the support plates 121 is to provide support and positioning for the edges of the film material during feeding and cutting, preventing the film edges from sagging or deviating, ensuring that the film material remains flat and stable during slitting, and further improving the accuracy of slitting. Additionally, the guide roller 400 is equipped with a tension adjustment structure (such as a spring tensioning device or a screw adjustment device). The tension adjustment structure can flexibly adjust the tension of the guide roller 400 on the film material according to factors such as the material, thickness, and feeding speed of the film material, ensuring that the film material maintains an appropriate tension during feeding, avoiding slack or excessive tightness, and guaranteeing slitting quality and production stability. Furthermore, the frame 100 is equipped with a human-machine interface component 700 (such as a touch screen or operation panel), which is connected to the control system of the device. Operators can easily set the device's operating parameters, such as the film feeding step length, cutting speed, and heating temperature, through the human-machine interface component 700, and monitor the device's operating status in real time, such as the current production quantity and fault alarm information. The human-machine interface component 700 improves the ease of operation and intelligence of the device, enabling operators to more easily control and manage the production process.
[0049] The cutting component 500 of this invention employs a cutter 511 adapted to the irregular contours of the packaging bag, enabling precise cutting of irregularly shaped tea packaging bags made of environmentally friendly materials such as biodegradable plastics. This overcomes the limitation of traditional cutting devices that can only cut rectangular packaging bags, meeting the market's demand for diversified packaging. By setting up a take-up roller 600 and a reasonable material feeding path, the device can automatically and orderly wind up and collect the scraps generated during the cutting process, achieving centralized processing of scraps, avoiding waste of raw materials and environmental pollution, while simplifying cleaning work and improving production efficiency. A stepping rotary drive device controls the rotation of the unwinding roller and the take-up roller 600, realizing stepping material feeding. This precise material feeding control method ensures that the cutting size of each packaging bag is accurate and consistent, improving product quality and stability. The design of the inner pressure strip 512, outer pressure strip 513, and buffer spring 514 in the cutting assembly 500 enables progressive pressing and cutting of the film material, ensuring cutting quality while avoiding hard collisions between the cutter 511 and the sliding base 120, thus extending the service life of the equipment. The electric heating element 516 and the heat-dissipating plate 517 inside the inner pressure strip 512 can heat and soften the heat-sealing part of the film material, improving the sealing performance of the packaging bag.
[0050] In summary, the environmentally friendly tea packaging bag cutting device of this utility model has an innovative structure and significant advantages. It can effectively solve the problems existing in traditional cutting devices, meet the market demand for the production of irregularly shaped environmentally friendly tea packaging bags, and has broad application prospects and market value.
