Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Embodiment 1 of this utility model, as follows: Figure 1 As shown, this embodiment is a fully automatic film-sealing machine structure, including a frame component 1, a bag-suction component 3, a bottle-loading mechanism 2, and a bag-holding component 4. The bag-suction component 3 includes an upper bag-suction mechanism 31 and a lower bag-suction mechanism 32 installed opposite to each other, as shown below. Figure 7As shown, the upper suction bag mechanism 31 includes a vertically installed upper suction bag cylinder 311 and a suction cup assembly 312 connected to the output end of the upper suction bag cylinder 311. The lower suction bag mechanism 32 includes a bag conveying area 6 set on the surface of the frame component 1. In this embodiment, the lower suction bag mechanism 32 is an array of suction holes opened on the conveyor belt of the pulley assembly. A suction module is set below the conveyor belt facing the suction bag component 3 to open the upper and lower sides of the bag opening of the bag film to facilitate the bottle to enter and complete the film covering action. The upper bottle mechanism 2 includes a feeding platform 21 set behind the suction bag component 3. A bottle pushing cylinder assembly 7 is installed on the side of the feeding platform 21 and is perpendicular to the direction of bottle movement on the feeding platform 21 to push the bottle to the suction bag component 3. Two bag supporting plates 33 matching the bottle size are set between the suction bag component 3 and the upper bottle mechanism 2. The bag supporting plates 3 are arranged opposite each other and connected to a synchronous opening and closing mechanism 34 installed below the frame component 1. The feeding platform 21 adopts a chain drive conveyor belt. Positioning mechanisms 22, perpendicular to the conveying direction, are equidistantly installed on the surface of the transmission conveyor belt. In this embodiment, the positioning mechanism consists of two L-shaped vertical plates arranged opposite each other. The bag conveying area 6 is a pulley assembly installed on the frame component 1 and arranged parallel to the chain drive conveyor belt. A bag feeding mechanism 5 is provided on the side of the end of the bag feeding area 6 near the bottle pusher cylinder assembly 7. The bag feeding mechanism 5 includes a horizontally arranged bag feeding cylinder 51, which moves the sheet-like bag film from the bag storage component 4 to the bag feeding area 6. A bag taking cylinder 53 located at the top of the bag film placement area 42 is installed on the connecting plate 52 at the output end of the bag feeding cylinder 51. The bag taking cylinder 53 is vertically installed and has an adjustable bag taking suction cup 54 at its output end. In this embodiment, the bag feeding cylinder 51 of the bag feeding mechanism 5 adopts a slide cylinder structure. A pusher plate 55 is installed on the side of the slide cylinder structure away from the bag taking cylinder 53. A bag storage component 4 is provided on the side of the bag feeding area 6 away from the bottle feeding mechanism 2. A bag opening and sealing component 8 is provided on the side of the suction component 3.
[0029] like Figure 8 As shown, the synchronous opening and closing mechanism 34 includes a horizontally arranged adjusting plate 341. Driven sprockets 342 are installed at both ends of the adjusting plate 341. A first slide rail 343 is installed on the surface of the adjusting plate 341 between the driven sprockets 342. The sliders on the surface of the first slide rail 343 are respectively connected to two bag-supporting paddles 33. The sides of the sliders are connected to a chain structure installed on the driven sprockets 342. One set of sliders is connected to the output end of a pen-shaped cylinder 344 located below the adjusting plate 341. A horizontal position adjusting cylinder 345 is installed on the side of the adjusting plate 341. When the pen-shaped cylinder drives the slider to slide along the first slide rail, it drives the other set of sliders to move in opposite directions through the chain, ensuring the synchronization rate of the bag-supporting paddle actions.
[0030] like Figure 3 and Figure 4As shown, the bag storage component 4 includes a horizontally arranged mounting plate 41. Two sets of bag film placement areas 42 are arranged on the surface of the mounting plate 41 along the movement direction of the bag conveying area 6. A width adjustment component composed of a screw mechanism is arranged at the bottom of the mounting plate corresponding to the position of the bag film placement area. This component is used to adjust the width of the bag film placement area to accommodate bag film structures of different specifications. A second slide rail 43 parallel to the bag conveying area 6 is arranged below the mounting plate 41. The slider on the second slide rail 43 is connected to the bottom of the mounting plate 41. A slide cylinder 44 located between the second slide rails 43 is installed at the bottom of the mounting plate 41. The two ends of the slide cylinder 44 are fixed to the frame component 1. The number of bags in the bag film placement area is detected by the sensor component above. When the bag film is insufficient, the slide cylinder drives the bag storage component to move laterally, moving another set of fully loaded bag film placement areas to below the upper bag mechanism. The empty bag film placement areas are replenished with bags, realizing continuous production without stopping the machine.
[0031] like Figure 2 As shown, the bag sealing component 8 includes a flattening assembly 82 mounted on a mounting frame 81. A top plate 83 is fixed to the top of the mounting frame 81. The flattening assembly 82 includes a drive cylinder 821 located behind the mounting frame 81. The output end of the drive cylinder 821 is connected to a flattening frame 823 located below the top plate. A third slide rail 822 is provided at the bottom of the top plate 83. The slider of the third slide rail 822 is connected to the top of the flattening frame 823. A horizontally arranged bidirectional screw is installed inside the side of the flattening frame 823 away from the drive cylinder 821. Flattening claws 824 are symmetrically arranged on the threaded section of the bidirectional screw. An upper sealing assembly 84 and a lower sealing assembly 85 are respectively installed on the side of the mounting frame 81 near the bag conveying area 6. The sealing blocks 86 of the upper sealing assembly 84 and the lower sealing assembly 85 are arranged opposite each other. The surface of the sealing block 86 is provided with a serrated structure. After the film is covered, the flattening assembly moves toward the bag conveying area and inserts two sets of flattening claws into the bag opening. The servo motor behind the bidirectional screw starts and drives the flattening claws to move on both sides, opening the circular bag opening into a long strip shape. Then the upper sealing assembly and the lower sealing assembly move toward the bag opening, and the flattening assembly retracts until the flattening claws leave the bag opening. The serrated structure of the two sets of sealing blocks completes the sealing operation.
[0032] In this embodiment, the feeding mechanism and bag hopper components achieve a fully automated production mode through photoelectric switches and sensors. After one set of bag film placement areas in the bag hopper component becomes empty, the bag film replacement operation is completed without stopping the machine by changing position via the second slide rail. After the film is applied, the bag is sealed by the bag unfolding and sealing component on the side of the bag conveying area. The fully automated control saves labor costs and is suitable for high-speed, large-volume film application operations.
[0033] Embodiment two of this application, such as Figure 5 and Figure 6As shown, the difference from Embodiment 1 is that this embodiment is a semi-automatic film-packing mechanism. The feeding platform 21 adopts an inclined platform component. The bottle is manually placed on the high part of the inclined platform component and rolled into the positioning mechanism 22 in front of the bottle-pushing cylinder assembly 7 by gravity. In this embodiment, the positioning mechanism is a long strip block structure with an arc-shaped groove on the top to provide positioning for the bottle. The bag conveying area 6 is a plate fixed to the surface of the frame component 1. With the same upper bag suction mechanism structure, the lower bag suction mechanism 32 is a suction cup set above the plate. The bag storage component 4 is a bag film placement area installed on the surface of the plate. In the upper bag mechanism 5, the connecting plate 52 is provided with a bottle-pushing plate 56 on the side away from the bag-taking cylinder 53. Compared with In the fully automated production mode of Embodiment 1, both bottle loading and bag film replacement in this embodiment are semi-automatically controlled. The operator places the bottle on the high part of the inclined platform and rolls it to the positioning mechanism. The bag loading mechanism picks up the bag film from the bag bin and moves it to the bag conveying area. The bag suction component opens the bag opening of the bag film. The synchronous opening and closing mechanism drives two bag-supporting paddles to extend into the bag film and open to both sides, so that the bag opening is opened to the maximum state. The bottle pushing cylinder assembly pushes the bottle in the positioning mechanism into the bag film. The bag loading mechanism and the synchronous opening and closing mechanism reset. During the process of grabbing the next set of bag film, the bottle pushing plate pushes the bottle with the film completed away from the bag conveying area, completing the sequential filming action. The operation is simple and suitable for small batch filming operations or debugging.
[0034] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
