Description

Technical Field

[0001] The invention relates to the technical field of laminating devices, in particular to an integrated fully automatic laminating machine. Background Art

[0002] Within the diverse field of packaging equipment, laminating machines, with their diverse range of types and functions, demonstrate exceptional adaptability and flexibility, making them widely used across numerous industries. Specifically, laminating equipment tailored for crisper containers tightly adheres plastic film to the container's opening, creating a seamless and effective seal. This process not only ensures the container's tight seal but also creates an ideal storage environment for food, medicine, and other items within. By isolating the container from air, moisture, and microorganisms, it minimizes spoilage, effectively preserving its freshness, taste, and quality, providing a solid guarantee for product quality and safety.

[0003] However, most automatic laminating machines currently on the market have limitations. Most can only laminate one crisper box at a time. This single-operation model clearly cannot meet the high-efficiency demands of large-scale assembly line production, hindering productivity gains. To address this issue, a new type of laminating machine has emerged that can simultaneously laminate multiple crisper boxes arranged in a square array. This innovative design significantly improves laminating efficiency, making the production process more efficient and faster.

[0004] However, after this batch lamination, the fresh-keeping boxes will stick together and need to be further separated into individual fresh-keeping boxes using a trimming machine. In actual production, the trimming machine and laminating machine usually operate independently, which makes the transfer of products between the two a key problem. Currently, product transfer mainly relies on manual operation or automatic conveyor belts. Manual conveying is not only time-consuming and labor-intensive, but also prone to human errors, affecting production efficiency and product quality. Although the use of automatic conveyor belts improves conveying efficiency to a certain extent, it will cause secondary positioning problems for product trimming. Accurate secondary positioning is crucial to ensuring trimming quality and product precision. If the positioning is inaccurate, it may lead to problems such as uneven trimming and dimensional deviation, which in turn affects the appearance and performance of the product.

[0005] Therefore, how to achieve efficient and accurate transfer of products between the laminating machine and the trimming machine has become the key to improving production efficiency and production accuracy. Summary of the Invention

[0006] This invention overcomes the shortcomings of existing technologies by providing an integrated, fully automatic laminating machine. After laminating the packaging box, the film directly moves the box to the automatic trimming device, achieving a seamless integration of the laminating and trimming processes. This eliminates the need for additional handling equipment or manual intervention required to transfer the boxes, reduces waiting time and handovers between processes, and makes the entire production process more compact and efficient.

[0007] In order to solve the above technical problems, the invention is achieved through the following technical solutions: An integrated fully automatic laminating machine, including a film assembly, a laminating assembly, an automatic trimming device, and a waste film recovery assembly; The film assembly is provided with a film frame for mounting a rolled film. The laminating assembly includes a discharge component and a hot pressing component. The hot pressing component uses the film to coat the product on the discharge component. After lamination, the packaging box is brought to the automatic trimming device during the movement of the film. The automatic edge trimming device trims the packaging boxes arranged in a square array after lamination, so that several packaging boxes stuck to the film at the same time can be separated independently; The automatic trimming device can move relative to the laminating assembly along the moving direction of the film under the drive of the motor.

[0008] Furthermore, the laminating assembly includes a discharge component and a hot pressing component, the discharge component includes a rotary drive motor and a rotary material rack, the center of the rotary material rack is connected to the rotary drive motor, and a first discharge station and a second discharge station are respectively provided on both sides of the rotary material rack; the first discharge station and the second discharge station are used to place discharge boxes, and one discharge box can hold no less than one packaging box; The hot pressing component is located above one side of the rotating material rack, and the rotary drive motor drives the rotating material rack to intermittently rotate 180 degrees so that the first unloading station and the second unloading station are alternately located below the hot pressing component; After being pulled out from the film frame, the film passes between the discharge component and the hot pressing component. Through the hot pressing of the hot pressing component, the packaging box placed on the first discharge station or the second discharge station is bonded to the film, and then carried to the next process by the film.

[0009] Furthermore, the discharge component includes a discharge component main frame, the discharge component main frame is slidably connected to a push-up inflation seat, the discharge component main frame is connected to a push-up cylinder, and the output end of the push-up cylinder is connected to the push-up inflation seat; A positioning column is provided on the main frame of the discharge component, and an edge positioning sleeve is provided on the discharge box. When the discharge box is placed on the first discharge station or the second discharge station, the edge positioning sleeve is sleeved on the positioning column, and the positioning column limits the discharge box in the horizontal direction.

[0010] Furthermore, the push-up inflatable seat is connected to the inflatable pipe, and an push-up positioning column is provided above the push-up inflatable seat. When the first discharge station or the second discharge station is below the hot pressing component, it is simultaneously located directly above the push-up inflatable seat. The upward push-up inflatable seat is used to push the discharge box toward the hot pressing component so that the upper surface of the packaging box can be hot-pressed together with the diaphragm; A lifting positioning sleeve is provided below the discharge box. When the push-up inflatable seat presses against the lower end of the discharge box to make it rise, the lifting positioning sleeve is sleeved on the push-up positioning column, and the push-up positioning column limits the horizontal direction of the discharge box.

[0011] Furthermore, a central inflation sleeve is provided under the discharge box. After the upper end surface of the packaging box has been bonded to the diaphragm, the inflation tube pushes upward to inflate the inflation seat, and finally transitions to the interior of the discharge box through the central inflation sleeve, thereby pushing the packaging box out of the discharge box.

[0012] Furthermore, the film laminating assembly includes a frame structure, the frame structure includes a frame guide rod, a film clamping component is provided on the frame guide rod, and the film clamping component is located between the discharge component and the hot pressing component; The film clamping component includes a film clamping base, the film clamping base is connected to a first clamping cylinder and a second clamping cylinder, the first clamping cylinder is connected to a first clamping frame, and the second clamping cylinder is connected to a second clamping frame; The first clamping frame and the second clamping frame are concentrically arranged in a vertical direction.

[0013] Furthermore, the frame guide rod is further provided with a product moving support rod; The frame guide rod is connected to the diaphragm guide power shaft, and the diaphragm guide power shaft is connected to the power belt.

[0014] Furthermore, the frame guide rod is connected to the isolation component, and the isolation component includes two sets of isolation cylinders arranged opposite to each other, and the isolation cylinders are connected to the isolation movable plate; The isolation component is arranged between the film clamping component and the hot pressing component.

[0015] Furthermore, the hot pressing component includes a hot pressing base, the hot pressing base is connected to the hot pressing lifting cylinder, the output end of the hot pressing lifting cylinder is connected to the heating plate, and a protective cover is provided on the periphery of the heating plate.

[0016] Compared with the prior art, the beneficial effects of the invention are: 1. After laminating the packaging box, the film directly drives the box to the automatic trimming equipment, achieving seamless integration of the lamination and trimming processes. This eliminates the need for additional handling equipment or manual intervention to transfer the box as in traditional methods, reduces waiting time and handover links between processes, and makes the entire production process more compact and efficient.

[0017] 2. Because the packaging boxes are tightly bonded together by the film and driven to move, the relative positions of the boxes and the film remain stable during movement. This provides a good foundation for subsequent automatic trimming equipment to perform accurate trimming, greatly reducing the risk of inaccurate trimming due to box position changes, and improving the quality and precision of product trimming.

[0018] 3. With the movement of the automatic trimming equipment on the moving slide rail of the trimming equipment, the film drives the movement of the packaging box, which can synchronize the trimming time of the automatic trimming equipment on the packaging box with the hot pressing time of the hot pressing component. This synchronization enables the two key processes of laminating and trimming to be carried out in parallel, making full use of production time, avoiding equipment idleness and waiting, and effectively improving the overall operation efficiency of the production line.

[0019] 4. The diaphragm-driven movement of the packaging box allows for more coordinated operation of the entire production line, allowing each process to proceed in an orderly manner according to a predetermined rhythm, reducing production bottlenecks and disruptions that can arise from process asynchrony. This coordination helps improve production stability and continuity, ensuring consistent product quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The preferred embodiments of the invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention and are not used to limit the invention.

[0023] like Figures 1 to 10 As shown, the integrated fully automatic laminating machine includes an overall frame 6, on which are arranged a film assembly 1, a laminating assembly 2, an automatic trimming device 4 and a waste film recovery assembly 5; the film assembly 1 is provided with a film rack 101, which is used to install a rolled film, and the laminating assembly 2 includes a discharge component 204 and a hot pressing component 205, which uses the film to laminate the product on the discharge component 204; after lamination, the packaging box 3 is brought to the automatic trimming device 4 during the movement of the film; the automatic trimming device 4 trims the packaging boxes 3 distributed in a square array after lamination, so that the packaging boxes 3 stuck to the film at the same time can be separated independently.

[0024] The whole frame 6 is provided with a trimming device moving slide rail 601, and the automatic trimming device 4 includes a trimming moving motor 401, which drives the automatic trimming device 4 to move on the trimming device moving slide rail 601. The waste film recovery component 5 is used to recover the waste film after the packaging box 3 is cut by the automatic trimming device 4; After the lamination is completed, the packaging box 3 is brought to the automatic trimming equipment 4 during the movement of the film. In order to synchronize the trimming time of the packaging box 3 by the automatic trimming equipment 4 with the hot pressing time of the hot pressing component 205, and to ensure that the trimming position of the packaging box 3 by the automatic trimming equipment 4 is accurate, a moving motor 401 is provided to drive the automatic trimming equipment 4 to move on the trimming equipment moving slide rail 601, so that the packaging box 3 can be accurately laminated and trimmed, and at the same time, the two processes of lamination and trimming can be carried out simultaneously, making the operation of the production line more synchronized and coordinated, thereby ensuring production efficiency and product quality.

[0025] The laminating assembly 2 includes a discharge component 204 and a hot pressing component 205. The discharge component 204 includes a rotary drive motor 2045 and a rotating material rack 2044. The center of the rotating material rack 2044 is connected to the rotary drive motor 2045. A first discharge station and a second discharge station are respectively provided on both sides of the rotating material rack 2044. The first discharge station and the second discharge station are used to place discharge boxes 2046. A discharge box 2046 can hold no less than one packaging box 3. The hot pressing component 205 is located above one side of the rotating material rack 2044. The rotary drive motor 2045 drives the rotating material rack 2044 to intermittently rotate 180 degrees so that the first discharge station and the second discharge station are alternately located below the hot pressing component 205. During operation, if the second discharge is initially under the hot pressing component 205, the operator first arranges the packaging box 3 and places it inside the discharge box 2046 of the first discharge station, and then presses the control button to make the rotary drive motor 2045 drive the rotary material rack 2044 to rotate, so that the first discharge station and the second discharge station exchange positions. When the first discharge station is under the hot pressing component 205, the hot pressing component 205 presses the diaphragm down so that the packaging box 3 placed inside the discharge box 2046 of the first discharge station is bonded together with the diaphragm. After the bonding is completed, the discharge box 2046 will hold the packaging box 3. The diaphragm is pushed out and enters the next process with the packaging box 3. During the time when the hot pressing component 205 presses down the diaphragm, the operator synchronously arranges the packaging box 3 and places it inside the discharging box 2046 of the second discharging station. Then the rotary drive motor 2045 continues to drive the rotating material rack 2044 to rotate, so that the first discharging station and the second discharging station exchange positions again. At this time, the second discharging station is under the hot pressing component 205. Similarly, the operator alternately discharges materials into the discharging boxes 2046 of the first discharging station and the second discharging station, so that the equipment continues to coat and seal the packaging box 3.

[0026] This arrangement enables the hot pressing component 205 to perform lamination and heat sealing on one or more packaging boxes 3 at one time, thereby greatly improving the efficiency of lamination and heat sealing on the packaging boxes 3. Secondly, since the packaging boxes 3 are placed in the discharge box 2046 for positioning and then lamination and heat sealing, the problem of inaccurate positioning of the packaging boxes 3, which leads to subsequent lamination misalignment, is avoided, thereby ensuring the stability of the equipment operation.

[0027] The membrane assembly 1 is provided with a membrane frame 101 and a membrane tensioning mechanism 102. The membrane frame 101 is used to mount the rolled membrane, providing support and storage for the membrane, facilitating its unfolding and use. The membrane tensioning mechanism 102 is used to tighten the membrane, keeping it flat and ensuring a tight fit when bonding it to the packaging box 3. By tightening the membrane, wrinkles or looseness of the membrane are avoided, improving the quality and effect of the lamination and making the adhesion between the membrane and the packaging box more secure and smooth. After being pulled out of the membrane frame 101, the membrane passes between the discharge component 204 and the hot pressing component 205. Through the hot pressing of the hot pressing component 205, the packaging box 3 placed on the first discharge station or the second discharge station is bonded to the membrane, and then carried to the next process by the membrane.

[0028] The discharge component 204 includes a discharge component main frame 2041, and the discharge component main frame 2041 is slidably connected to an upward push-up inflation seat 2043. The upward push-up inflation seat 2043 is used to push the discharge box 2046 toward the hot pressing component 205 so that the upper surface of the packaging box 3 can be hot-pressed together with the film; at the same time, it serves as an inflation channel to transfer gas to the inside of the discharge box 2046, so that the discharge box 2046 can smoothly push out the coated packaging box 3. The discharge component main frame 2041 is connected to the upward push cylinder 2042, and the output end of the upward push cylinder 2042 is connected to the upward push-up inflation seat 2043.

[0029] A positioning column 204C is provided on the main frame 2041 of the discharge component, and an edge positioning sleeve 204F is provided on the discharge box 2046. When the discharge box 2046 is placed on the first discharge station or the second discharge station, the edge positioning sleeve 204F is sleeved on the positioning column 204C. The positioning column 204C limits the discharge box 2046 in the horizontal direction, ensuring the accuracy of the placement of the discharge box 2046, improving the positioning accuracy of the discharge box 2046, ensuring the accurate position of the packaging box 3 during the hot pressing process, and avoiding the problem of film dislocation caused by the position deviation of the discharge box.

[0030] The push-up inflatable seat 2043 is connected to the inflatable tube 204A. A push-up positioning column is provided above the push-up inflatable seat 2043. When the first discharge station or the second discharge station is below the hot pressing component 205, it is simultaneously located directly above the push-up inflatable seat 2043. The upward push-up inflatable seat 2043 is used to push the material discharging box 2046 toward the hot pressing component 205 so that the upper surface of the packaging box 3 can be hot-pressed together with the film; A lifting positioning sleeve 204E is provided below the discharge box 2046. When the upward push-up inflatable seat 2043 presses against the lower end of the discharge box 2046 to make it rise, the lifting positioning sleeve 204E is sleeved on the upward push-up positioning column, and the upward push-up positioning column limits the horizontal direction of the discharge box 2046.

[0031] A central inflation sleeve 204G is provided under the discharge box 2046. When the upper end surface of the packaging box 3 has been bonded to the diaphragm, the inflation tube 204A pushes upward to inflate the inflation seat 2043, and finally transitions to the inside of the discharge box 2046 through the central inflation sleeve 204G, thereby pushing the packaging box 3 out of the discharge box 2046. The packaging box 3 is fully utilized and covered on the discharge box 2046 after being bonded to the diaphragm, so that the inner cavity of the discharge box 2046 reaches a sealed state, and the packaging box 3 is pushed out by inflation. The operation is simple and convenient, and can ensure that the pushing force is uniform, thereby avoiding damage to the packaging box.

[0032] The laminating assembly 2 includes a frame structure 201, the frame structure 201 includes a frame guide rod 2011, and a film clamping component 203 is provided on the frame guide rod 2011, and the film clamping component 203 is located between the discharge component 204 and the hot pressing component 205; this layout enables the film to be processed by the film clamping component 203 in a timely manner during the process from discharge to hot pressing, thereby ensuring the continuity and efficiency of the laminating process and reducing unnecessary loss and interference during the film transmission process.

[0033] The film clamping component 203 includes a film clamping base 2031, which is connected to a first clamping cylinder 2032 and a second clamping cylinder 2035. The first clamping cylinder 2032 is connected to a first clamping frame 2033, and the second clamping cylinder 2035 is connected to a second clamping frame 2036. The first clamping frame 2033 and the second clamping frame 2036 are arranged concentrically in the vertical direction, ensuring consistency and precision in the movement of the two clamping frames. When clamping the film, the clamping force can be applied more evenly, avoiding problems such as wrinkling and damage caused by uneven force, thereby improving the quality of the film.

[0034] A product moving support rod 2012 is also provided on the frame guide rod 2011; since the packaging box 3 is pushed out from the discharge box 2046, the packaging box 3 is only driven by the adhesion of the membrane, so the product moving support rod 2012 is provided to push the weight of the packaging box 3 and the product therein, so that the membrane will not be torn off, and the transportation of the packaging box 3 is more stable and safe.

[0035] The frame guide rod 2011 is connected to the diaphragm guide power shaft 2013, and the diaphragm guide power shaft 2013 is connected to the power belt 2014. The diaphragm guide power shaft 2013 and the power belt 2014 are used to drive the diaphragm to move, so that the diaphragm can drive the packaging box 3 to the next process.

[0036] The frame guide rod 2011 is connected to the isolation component 202, which includes two sets of isolation cylinders 2021 arranged opposite each other. The isolation cylinders 2021 are connected to the isolation movable plates 2022. The isolation component 202 is arranged between the film clamping component 203 and the hot pressing component 205. The isolation component 202 is used to separate the film from the hot pressing component 205. After the film is hot-pressed by the isolation component 202, it adheres to the packaging box 3. However, similarly, the side of the film away from the packaging box 3 is also difficult to separate from the hot pressing component 2052. To prevent the film from not being separated from the hot pressing component 2052 when being pulled, the two sets of isolation cylinders 2021 will drive the two sets of isolation movable plates 2022 to move toward the center simultaneously, separating the film from the hot pressing component 2052. After the separation is completed, the two sets of isolation cylinders 2021 will drive the two sets of isolation movable plates 2022 to move to the sides simultaneously, waiting for the next action.

[0037] The hot pressing component 205 includes a hot pressing base 2051, which is connected to a hot pressing lifting cylinder 2052. The output end of the hot pressing lifting cylinder 2052 is connected to a heating plate 2053. A protective cover 2054 is provided on the periphery of the heating plate 2053. The protective cover 2054 can prevent hot air from leaking out and can also prevent the operator from being scalded by the heating plate 2053, thereby ensuring the safety of the equipment operation.

[0038] The workflow is as follows: First, the rolled film is mounted on the film frame 101 of the film assembly 1, and the film tensioning mechanism 102 tightens the film to make it flat, ensuring that the film can fit tightly to the packaging box during the subsequent lamination process.

[0039] At the first and second unloading stations of the rotating rack 2044, unloading boxes 2046 are placed, respectively. Boxes 2046 are attached to positioning posts 204C of the unloading assembly main frame 2041 via side positioning sleeves 204F, achieving precise horizontal positioning. Assuming the second unloading station is initially positioned below the hot pressing assembly 205, an operator arranges and places packaging boxes 3 inside unloading box 2046 at the first unloading station.

[0040] The operator presses the control button, and the rotary drive motor 2045 drives the rotary material rack 2044 to rotate 180 degrees, so that the first discharge station and the second discharge station exchange positions, and the first discharge station moves to the bottom of the hot pressing component 205.

[0041] The upward push cylinder 2042 on the main frame 2041 of the discharge component drives the upward push inflation seat 2043 to move upward, and the upward push inflation seat 2043 presses against the lower end of the discharge box 2046. The discharge box 2046 is connected to the upward push positioning column through the lifting positioning sleeve 204E to ensure accurate horizontal positioning. The upward push inflation seat 2043 pushes the discharge box 2046 toward the hot pressing component 205 to make the upper surface of the packaging box 3 contact the diaphragm.

[0042] The first clamping cylinder 2032 and the second clamping cylinder 2035 of the film clamping component 203 respectively drive the first clamping frame 2033 and the second clamping frame 2036 to uniformly clamp the film pulled out from the film rack 101 and passing through the discharge component 204 and the hot pressing component 205 to ensure that the film is flat.

[0043] The hot pressing lifting cylinder 2052 of the hot pressing component 205 drives the heating plate 2053 to descend, and performs hot pressing on the diaphragm and the packaging box 3, so that the diaphragm and the packaging box 3 are bonded together. In this process, the shield 2054 prevents the heat from leaking out, and avoids the operator from being scalded by the heating plate 2053.

[0044] Once the upper end of the packaging box 3 is bonded to the diaphragm, the inflation tube 204A pushes upward to inflate the inflation seat 2043. The gas then flows through the central inflation sleeve 204G into the discharge box 2046, ejecting the packaging box 3 from the discharge box 2046. The diaphragm guide shaft 2013 and the power belt 2014 drive the diaphragm to move, and the diaphragm carries the packaging box 3 to the next step. To prevent the diaphragm from adhering to the hot pressing component 205, the two isolation cylinders 2021 of the isolation component 202 simultaneously move the two isolation movable plates 2022 toward the center, separating the diaphragm from the hot pressing component 205. Once completed, the two isolation cylinders 2021 drive the two isolation movable plates 2022 to move simultaneously to the sides, awaiting the next operation.

[0045] At the same time, when the hot pressing component 205 is performing the hot pressing operation, the operator simultaneously arranges the packaging boxes 3 and places them inside the discharge box 2046 of the second discharge station.

[0046] The rotary drive motor 2045 continues to drive the rotary material rack 2044 to rotate, so that the first discharge station and the second discharge station exchange positions again, repeating the above-mentioned laminating operation to achieve continuous laminating and sealing of the packaging box 3 by the equipment.

[0047] During the movement of the packaging box 3 after lamination driven by the film, the trimming moving motor 401 drives the automatic trimming device 4 to move on the trimming device moving slide rail 601, so that the trimming time of the automatic trimming device 4 is synchronized with the hot pressing time of the hot pressing component 205, and ensures that the trimming position of the packaging box 3 is accurate.

[0048] When the packaging boxes 3 distributed in a square array after lamination move to the automatic trimming device 4, the automatic trimming device 4 trims them, separating the packaging boxes 3 stuck on the film at the same time into individual packaging boxes 3, and the individual packaging boxes 3 are output from the side of the automatic trimming device 4.

[0049] The waste film recovery component 5 recovers the waste film after the packaging box 3 is cut off by the automatic trimming device 4, completing the entire production process.

[0050] This invention uses a film sheet to directly move the packaging box to the automatic trimming equipment after laminating the box, achieving seamless integration of the lamination and trimming processes. This eliminates the need for additional handling equipment or manual intervention required to transfer the box in traditional methods, reduces waiting time and handovers between processes, and makes the entire production process more compact and efficient.

[0051] Because the packaging boxes are tightly bonded together by the film and driven to move, the relative positions of the boxes and the film remain stable during movement. This provides a good foundation for subsequent automatic trimming equipment to perform accurate trimming, greatly reducing the risk of inaccurate trimming due to box position changes, and improving the quality and precision of product trimming.

[0052] By aligning the automatic trimming machine with its sliding rails, the film drives the box's movement, synchronizing the automatic trimming process with the hot-pressing process. This synchronization allows the two critical processes, laminating and trimming, to proceed in parallel, effectively maximizing production time, avoiding idle equipment and waiting times, and improving the overall efficiency of the production line.

[0053] The diaphragm's movement of the packaging box ensures a more coordinated operation of the entire production line. Each process proceeds in an orderly manner according to a predetermined rhythm, reducing production bottlenecks and disruptions that can arise from asynchronous processes. This coordination improves production stability and continuity, ensuring consistent product quality.

[0054] There is no need to set up additional large-scale handling equipment specifically for transferring packaging boxes, which reduces equipment purchase and maintenance costs. At the same time, it also saves space in the production workshop, makes the production layout more compact and reasonable, and improves space utilization.

[0055] Finally, it should be noted that the above are only preferred embodiments of the invention and are not intended to limit the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the invention should be included in the scope of protection of the invention.
