Technical Field
[0001] This application relates to the field of bubble wrap processing technology, and in particular to a bubble wrap production and processing equipment and method. Background Technology
[0002] Bubble wrap, also known as air cushion film, bubble wrap, or bubble cloth, is a plastic packaging material made primarily of high-pressure polyethylene, with added whitening agents, opening agents, and other auxiliary materials. It is produced through high-temperature extrusion and thermoforming at 230℃, followed by multi-layer lamination. This material possesses shock-absorbing, impact-resistant, heat-sealing, moisture-proof, and corrosion-resistant properties, and belongs to the category of shock-resistant protective packaging materials under the chemical product classification. In the packaging industry, bubble wrap is a commonly used cushioning packaging material, widely used for the transportation and protection of various fragile items such as electronics, furniture, and glass products.
[0003] Regarding the aforementioned technologies, traditional bubble wrap production equipment has a low degree of automation and involves many manual operations, resulting in low production efficiency, and therefore needs to be improved. Summary of the Invention
[0004] To improve the production efficiency of bubble wrap, this application provides bubble wrap production and processing equipment and method.
[0005] Firstly, the bubble wrap production and processing equipment provided in this application adopts the following technical solution: A bubble wrap production and processing device includes a frame and an extruder mounted on the frame. The frame is provided with an output mold that communicates with the output end of the extruder. The output mold is used to produce two layers of film. The frame is provided with a forming component for driving the two layers of film to adhere and form bubbles. A frame is provided on one side of the frame. A winding component for winding the formed film is provided at the end of the frame away from the frame. A dividing component is provided between the winding component and the forming component for cutting the film.
[0006] By adopting the above technical solution, the extruder melts the raw material and extrudes it into the discharge mold. The discharge mold outputs two layers of film. The forming component drives the two layers of film to bond and form bubbles. The winding component winds up the formed film, and the slitting component cuts the formed film, thereby achieving efficient production of bubble film.
[0007] Preferably, the forming assembly includes a mounting frame, two sets of forming sleeves, a guide roller, a rotating component, and a suction component. The mounting frames are positioned opposite each other at both ends of the upright frame, and both forming sleeves are rotatably positioned between the two sets of mounting frames to clamp the film. The guide roller is rotatably positioned between the two sets of mounting frames to guide the two sets of films to abut against the two sets of forming sleeves at intervals. Each forming sleeve has several sets of air grooves on its outer peripheral wall, and each forming sleeve has an air vent hole through its inner peripheral wall that communicates with the interior of the air grooves. The rotating component is mounted on the mounting frame to drive the two sets of forming sleeves to rotate towards each other. The suction component is located inside each set of forming sleeves to attract the film to adhere to the inner sidewall of the air groove.
[0008] By adopting the above technical solution, two sets of films pass between two sets of forming sleeves. The rotating component drives the two sets of forming sleeves to rotate in opposite directions. During the transportation of the films, the two sets of films are bonded by clamping the films. The suction component drives the two sets of films to move away from each other and attach to the inner wall of the air groove to stably form bubble films. The guide roller facilitates the change of the film's running path so that there is a gap between the two layers of films that facilitates air introduction, thereby facilitating the formation of bubbles in the films.
[0009] Preferably, the suction component includes a support cylinder, a ball bearing, a suction hood, an air extraction component, and an air outlet pipe; the support cylinder is disposed on one of a set of mounting brackets, and the support cylinder and the forming sleeve are respectively disposed one-to-one, and each support cylinder passes through the corresponding forming sleeve; the ball bearing is rotatably embedded in the outer peripheral wall of the support cylinder to support the forming sleeve; each support cylinder has a clearance opening through its side wall facing the film for connecting the air outlet hole, the suction hood is disposed inside the clearance opening, the air extraction component is disposed inside the support cylinder, the air extraction end of the air extraction component is connected to the inside of the suction hood, and the air outlet pipe is connected to the air outlet end of the air extraction component.
[0010] By adopting the above technical solution, the support cylinder and ball bearings stably support the forming sleeve, so that the rotating component can drive the forming sleeve to rotate outside the support cylinder; the air extraction component provides an attractive force to the inside of the suction hood, so that the suction hood always faces the film through the clearance port, and when the air groove and air outlet on the outer peripheral wall of the rotating forming sleeve are connected to the suction hood inside the clearance port, an attractive force is generated inside the air groove to drive the film to stably adhere to the inner side wall of the air groove, so that the attractive force generated by the suction component is concentrated, and the phenomenon of wasted attractive force generated by the suction component due to the connection of other non-working air grooves is reduced, thus saving resources.
[0011] Preferably, the rotating component includes a rotating shaft, a drive gear, a transmission gear, and a rotating motor; the rotating shaft is disposed at the end of each set of forming sleeves, and each rotating shaft is rotatably connected to a mounting frame away from the support cylinder; the drive gear is sleeved on one set of rotating shafts, the transmission gear is sleeved on another set of rotating shafts, and the drive gear and the transmission gear mesh with each other for transmission; the rotating motor is disposed on the mounting frame for driving one set of rotating shafts to rotate.
[0012] By adopting the above technical solution, the rotating motor drives one set of rotating shafts to rotate, and the driving gear and transmission gear mesh with each other to drive the two sets of rotating shafts to drive the two sets of forming sleeves to rotate in opposite directions, thereby realizing the drive.
[0013] Preferably, each of the rotating shafts is provided with a mounting sleeve for covering the end of the forming sleeve at its end, and each mounting sleeve is provided with a number of fastening bolts threaded onto the forming sleeve; the bottom of the mounting frame is provided with a fixed track for sliding the mounting frame, and the mounting frame is provided with a limiting component for limiting the displacement of the mounting frame.
[0014] By adopting the above technical solution, the mounting frame moves along the fixed track, allowing the support cylinder and the forming sleeve to separate from each other. By disassembling the fastening bolts, the forming sleeve and the mounting sleeve can be quickly separated, making it easy to replace the forming sleeve with air grooves of different diameters and combine them with the support cylinder. This allows the air grooves of different diameters to connect with the inside of the suction hood, facilitating the adsorption of air bubbles of different diameters onto the film. The limiting component restricts the position of the mounting frame, reducing the phenomenon of the mounting frame moving arbitrarily along the length of the fixed track.
[0015] Preferably, the limiting component includes a limiting frame, a limiting plate, and a limiting cylinder; the limiting frame is disposed at the bottom of each set of mounting frames, the limiting plate is slidably mounted on each set of limiting frames, and the limiting cylinder is disposed between each set of limiting frames and the corresponding limiting plate to drive the corresponding limiting plate to move up and down.
[0016] By adopting the above technical solution, the output end of the limit cylinder drives the limit plate to move up and down, so that the limit plate contacts the ground, thereby restricting the random movement of the mounting bracket.
[0017] Preferably, the segmentation assembly includes a landing gear, a positioning frame, a landing cylinder, a sliding seat, and a cutting blade; the landing gear is slidably mounted on the frame, the positioning frame is located on both sides of the frame in the width direction, and the landing cylinder is located between each set of positioning frames and the landing gear to drive the landing gear to move vertically; the sliding seat is slidably mounted on the landing gear along the length direction, and the landing gear has a through-cutting opening that extends along the length direction of the landing gear; the cutting blade is mounted on the sliding seat to penetrate the cutting opening and segment the film.
[0018] By adopting the above technical solution, the landing cylinder drives the landing gear to descend and press the film, and then the manual drive of the sliding seat drives the cutting blade to move to cut the film; the landing gear pressing the film reduces the wrinkles generated in the film during the cutting process, ensuring the flatness of the film cutting.
[0019] Preferably, the frame is provided with trimming blades on both sides in the width direction for trimming the edges of the cut film, and the frame is provided with a collection component for collecting waste.
[0020] By adopting the above technical solution, the trimming knife corrects the edges on both sides of the film width direction, and the collection component collects the waste, reducing the phenomenon of waste adhering to the film and improving the finished product quality of the film.
[0021] Preferably, the collection assembly includes a fixed frame, a collection roller, a collection motor, a mounting plate, a plug-in plate, and a discharge hook; the fixed frame is disposed on both sides of the frame in the width direction, the collection roller is rotatably disposed on the fixed frame for wrapping waste material; the collection motor is disposed on the fixed frame for driving the collection roller to rotate; the mounting plate is disposed on the side wall of the collection roller away from the collection motor, the plug-in plate is disposed on the side wall of the mounting plate facing the collection roller, and the side wall of the collection roller has a through-hole for the plug-in plate to abut against; the discharge hook is disposed at the end of the plug-in plate away from the mounting plate, and the discharge hook is exposed in the plug-in hole for unloading waste material.
[0022] By adopting the above technical solution, the waste material is wound around the outside of the collecting roller and the plug plate. The collecting motor drives the collecting roller to rotate the plug plate and the mounting plate to wind up the waste material. When it is necessary to remove the waste material, the mounting plate is pulled out to drive the plug plate to gradually separate from the plug notch, so that the unloading hook can hook the waste material wrapped on the outer wall of the collecting roller, so as to quickly remove the waste material from the collecting roller.
[0023] Secondly, This application provides a method for manufacturing bubble wrap, including the following steps: Plastic film: The raw material is poured into the extruder, the extruder melts the raw material and then guides it into the discharge die, the discharge die produces a thin film; Molding: Two thin films are introduced into the molding assembly, which drives the two films to bond and form bubbles; Slitting: The slitting component slits the foamed film; Rewinding: The rewinding unit rewinds the foamed film after it has been formed.
[0024] In summary, this application includes at least one of the following beneficial technical effects: By setting up an extruder, the raw materials are plasticized through its own screw conveying and heating operations. The plasticized raw materials enter the discharge die, which extrudes the raw materials into two-layer sheet films. The films then pass through the forming sleeve, where they form bubble film under the vacuum suction of the suction component. Then, the slitting component cuts the bubble film after it has been plasticized. Finally, the winding component winds up the cut bubble film into finished products, thereby improving the production efficiency of bubble film. The mounting frame moves along the fixed track, allowing the support cylinder and the forming sleeve to separate. By loosening the fastening bolts, the forming sleeve and the mounting sleeve can be quickly separated, facilitating the replacement of forming sleeves with air grooves of different diameters and their combination with the support cylinder. This allows the air grooves of different diameters to connect with the inside of the suction hood, thus facilitating the adsorption of air bubbles of different diameters onto the film. The limiting component restricts the position of the mounting frame, reducing the phenomenon of the mounting frame moving arbitrarily along the length of the fixed track. By setting an edge trimmer to correct the edges on both sides of the film width direction and using a collection component to collect waste, the phenomenon of waste adhering to the film is reduced, and the quality of the finished film is improved.
