Description

Technical Field

[0001] This application relates to the field of daily chemical product packaging technology, and in particular to a bottle boxing device with an inner liner. Background Technology

[0002] Before being packaged, cosmetic bottles typically need to be wrapped with an inner liner.

[0022] This application proposes a bottle-boxing device with an inner liner, referring to... Figure 1 In one embodiment, the liner-lined bottle cartoning equipment includes: The inner liner conveying mechanism 1 includes an inner liner conveying line 11 and a plurality of positioning components 12 disposed on the inner liner conveying line 11. The positioning components 12 are used to position the inner liner so that a portion of the inner liner structure is folded to form a space that can accommodate the bottle. The first closing mechanism 2 is located on one side of the conveying direction of the inner lining conveying mechanism 1 and is used to fold the fold on one side of the inner lining upward. The second closing mechanism 3 is located on the other side of the conveying direction of the inner lining conveying mechanism 1. The second closing mechanism 3 includes a lifting rod assembly for folding the fold on the other side of the inner lining upward. The second closing mechanism 3 also includes a guide plate assembly 36 and a pressure rod assembly 37 arranged sequentially along the conveying direction of the inner lining conveying mechanism 1. The guide plate assembly 36 is used to fold the fold on the other side of the inner lining upward, and the pressure rod assembly 37 is used to press the folded fold closed. The third closing mechanism 4 is located above the inner lining conveying mechanism 1 and is used to press the folded pages with the inner lining facing upward downward. The third closing mechanism 4 includes a first pressure plate assembly 41 and a second pressure plate assembly 42 arranged sequentially along the conveying direction of the inner lining conveying mechanism 1.

[0023] In this embodiment, after the bottle is placed into the space formed by the positioning component 12, the two ends of the inner liner and the side facing the conveying direction form folds to be folded, that is, the inner liner needs to be folded and wrapped from three directions to cover the bottle.

[0024] The equipment in this embodiment can adapt to two different sizes of linings. When folding and covering the first size lining, the first closing mechanism 2 folds the fold on one side of the lining upwards, the lifting rod assembly folds the fold on the other side of the lining upwards, and then the second pressure plate assembly 42 presses the upward-facing fold of the lining downwards, thus completing the folding and covering of the first size lining. When folding and covering the second size lining, the first closing mechanism 2 folds the fold on one side of the lining upwards, the guide plate assembly 36 folds the fold on the other side of the lining upwards, the pressure rod assembly 37 presses the folded fold together, and finally the first pressure plate assembly 41 presses the upward-facing fold of the lining downwards, thus completing the folding and covering of the second size lining. The first closing mechanism 2 is a common component in the folding process for both sizes of linings, while the other components selectively participate in the operation according to the lining size.

[0025] Reference Figure 2 and Figure 3 In some embodiments, the guide plate assembly 36 includes a guide plate 361, one end of which facing away from the pressure bar assembly 37 is provided with a guide ramp 362 for contacting the flap on the other side of the liner. The pressure bar assembly 37 includes a pressure bar and a first drive member 372 that moves the pressure bar closer to or away from the lining conveyor line 11. The pressure bar extends along the conveying direction of the lining conveyor mechanism 1.

[0026] In this embodiment, the guide plate 361 is a vertically arranged plate-shaped component with an overall trapezoidal shape. The guide slope 362 is formed at the narrower end of the trapezoid. When the inner lining passes through the guide plate assembly 36 along the conveying direction, the fold first contacts the guide slope 362 and gradually folds upward under the guidance of the guide slope 362, thereby transitioning the fold from a flat state to a flipped-up state.

[0027] The pressure bar assembly 37 is located downstream of the guide plate assembly 36 along the conveying direction. The side of the pressure bar closest to the guide plate 361 has a curved section extending outwards towards the inner liner conveying mechanism 1. This section guides the folded flap after passing through the guide plate 361 to smoothly transition to the pressing area of ​​the pressure bar. After the inner liner completes its initial folding via the guide plate assembly 36, it continues to be conveyed forward to the position of the pressure bar assembly 37. The first driving member 372 drives the pressure bar towards the inner liner conveying line 11, pressing the folded flap onto the outside of the bottle, ensuring that the folded flap will not spring back or return to its original position, thus completing the folding and pressing of the other side of the inner liner. In this embodiment, the first driving member 372 can adopt an existing linear drive structure.

[0028] Reference Figure 2 In some embodiments, the first closing mechanism 2 includes a top plate 21, the top plate 21 including an arcuate portion 211 for contacting the fold on one side of the liner, the arcuate portion 211 extending toward the liner conveying mechanism 1. A guide rod 22 is provided on the side of the top plate 21 facing away from the inner lining conveying mechanism 1. The guide rod 22 is inclined along the conveying direction of the inner lining conveying mechanism 1 and is used to guide the hinge on one side of the inner lining to contact the top plate 21.

[0029] In this embodiment, the guide rod 22 has a curved section that extends downward toward the side of the inner lining material. When the inner lining passes the first closing mechanism 2 along the conveying direction, the fold on one side first contacts the guide rod 22. Under the tilt angle of the guide rod 22, the fold is guided to gradually approach the top plate 21. The top plate 21 is a vertically arranged plate. One end of the top plate 21 forms an arc surface 211. The arc surface 211 extends from the main body of the top plate 21 to the center of the inner lining conveying mechanism 1 to form an arc surface. The fold contacts the arc surface 211 of the top plate 21 and folds upward under the guidance of the arc surface 211, completing the folding of the fold on one side of the inner lining.

[0030] Reference Figure 2 In some embodiments, the first pressure plate assembly 41 includes a first pressure plate 411, the lower end face of the first pressure plate 411 is used to contact the fold of the lining, and one end of the first pressure plate 411 is provided with an inlet member 412, the inlet member 412 is located above the first pressure plate 411, and the inlet member 412 is used to guide the fold of the lining to contact the first pressure plate 411. A side pressure plate 413 is provided on the side of the first pressure plate 411 facing away from the inner lining conveying mechanism 1. A second driving member 414 for driving the side pressure plate 413 to move closer to or away from the inner lining conveying mechanism 1 is also provided on the first pressure plate 411. The side pressure plate 413 is located between the top plate 21 and the first pressure plate 411.

[0031] In this embodiment, the first pressure plate 411 is horizontally arranged above the inner lining conveyor line 11. The first pressure plate 411 is generally long and narrow, and an inclined surface is formed at the end near the inner lining material to facilitate the introduction of the flap that contacts the inner lining. The guide member 412 is arranged on the upper end of the first pressure plate 411. The guide member 412 is an arc-shaped piece. The arc surface of the guide member 412 is connected to the inclined surface formed on the first pressure plate 411. When the inner lining moves along the conveying direction to the position of the first pressure plate assembly 41, the upward flap first contacts the guide part, and under the guidance of the guide part, it transitions to the inclined surface and lower end surface of the first pressure plate 411. The first pressure plate 411 then presses the flap downward.

[0032] The side pressure plate 413 has an L-shaped cross-section. The transition between the inclined surface and the lower end surface of the first pressure plate 411 is approximately flush with one end of the side pressure plate 413. During the folding and wrapping of the second-specification lining, if the upward-facing fold of the lining still partially curls up after entering below the first pressure plate 411 via the guide portion, the second driving member 414 drives the side pressure plate 413 toward the lining conveying mechanism 1, pressing the fold downwards. This ensures that the transition area between the fold on one side of the lining and the upward-facing fold is fully folded and fitted, preventing the fold from curling up or incomplete wrapping. In this embodiment, the second driving member 414 can adopt an existing linear drive structure.

[0033] Reference Figure 3 In some embodiments, the second pressure plate assembly 42 includes a second pressure plate 421 and an auxiliary pressure plate 422 arranged side by side along the width direction of the lining conveying mechanism 1, both the second pressure plate 421 and the auxiliary pressure plate 422 extending along the conveying direction of the lining conveying mechanism 1. The second pressure plate assembly 42 also includes a mounting base 423 for mounting the second pressure plate 421 and the auxiliary pressure plate 422. The mounting base 423 is disposed on the inner lining conveying mechanism 1. The second pressure plate 421 is fixedly disposed on the mounting base 423. The auxiliary pressure plate 422 is slidably disposed on the mounting base 423 along the width direction of the inner lining conveying mechanism 1.

[0034] In this embodiment, the mounting base 423 is erected above the lining conveyor line 11, spanning across it. The second pressure plate 421 and the auxiliary pressure plate 422 are suspended below the mounting base 423. Both the second pressure plate 421 and the auxiliary pressure plate 422 are elongated and horizontally arranged, extending along the conveying direction of the lining conveying mechanism 1. The ends of the second pressure plate 421 and the auxiliary pressure plate 422 near the material feeding direction of the lining are respectively formed with inclined surfaces for guiding the folds. When the lining moves along the conveying direction to the position of the second pressure plate assembly 42, the upward-facing fold first contacts the guiding inclined surface. Under the guidance of the guiding inclined surface, it is gradually pressed between the lower end surfaces of the second pressure plate 421 and the auxiliary pressure plate 422 and the main body of the lining, thereby completing the downward folding of the fold.

[0035] By adjusting the position of the auxiliary pressure plate 422 in the width direction, the spacing between the second pressure plate 421 and the auxiliary pressure plate 422, or the folding width covered by both, can be changed, thereby adapting to the differences in folding width at this station for different specifications of linings. When folding the first specification lining, the second pressure plate assembly 42 participates in the action as the main folding component, and the position of the auxiliary pressure plate 422 is adjusted according to the folding width of the first specification lining, so that the folding range matches the actual width of the lining fold, ensuring the consistency of the folding effect.

[0036] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the lifting rod assembly includes a first lifting rod 31 extending along the conveying direction of the lining conveying mechanism 1. The lifting rod assembly also includes a second lifting rod 32 and a third lifting rod 33 arranged sequentially along the conveying direction of the lining conveying mechanism 1. The second lifting rod 32 and the third lifting rod 33 are both located above the first lifting rod 31. In the width direction of the lining conveying mechanism 1, the first lifting rod 31, the second lifting rod 32 and the third lifting rod 33 are arranged sequentially toward the lining conveying line 11. The first lifting rod 31, the second lifting rod 32, and the third lifting rod 33 each include a straight section 34 and an arc-shaped section 35 for guiding the fold of the liner on the other side to contact the straight section 34; the arc-shaped section 35 of the first lifting rod 31 is bent downwards and extended.

[0037] In this embodiment, when folding the first specification liner, the fold on the other side of the liner first contacts the arc-shaped segment 35 of the first lifting rod 31. Since the arc-shaped segment 35 bends downward, it can guide the fold from a lower position to the straight segment 34 of the first lifting rod 31, completing the initial lifting of the fold. The straight segment 34 of the first lifting rod 31 continues to extend along the conveying direction to the end of the third lifting rod 33, that is, to the second pressure plate assembly 42. The liner continues to move forward along the conveying direction, and the fold passes through the second lifting rod 32 and the third lifting rod 33 in sequence. Since the three lifting rods are arranged sequentially toward the liner conveying line 11 in the width direction, the fold is further folded inward when passing each lifting rod. When it reaches the third lifting rod 33, the fold is folded to a near-horizontal state. Both ends of the third lifting rod 33 are provided with arc-shaped segments 35, and the extension directions of the arc-shaped segments 35 at the two ends are opposite. The arc-shaped section 35 at the end near the material feeding direction of the inner lining is used to introduce the fold on the other side of the inner lining, so that the fold smoothly transitions to the straight section 34 of the third lifting rod 33; the arc-shaped section 35 at the end away from the material feeding direction of the inner lining extends toward the second pressure plate assembly 42, and is used to guide the fold that has been folded to a near-horizontal state by the third lifting rod 33 to the second pressure plate assembly 42, thus completing the connection between the lifting rod assembly and the second pressure plate assembly 42.

[0038] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the lining conveying mechanism 1 includes a frame 13 for mounting the lining conveying line 11; the first closing mechanism 2, the lifting rod assembly, the guide plate assembly 36, the pressure rod assembly 37 and the first pressure plate assembly 41 are all mounted on the frame 13 via an adjusting seat 14; The adjustment seat 14 includes a mounting part 141 and a fixing part 142 for connecting the frame 13. The mounting part 141 is fixedly disposed on the first adjustment plate 143. The first adjustment plate 143 is slidably disposed on the second adjustment plate 144 in the horizontal direction. The second adjustment plate 144 is slidably disposed on the fixing part 142 in the vertical direction.

[0039] In this embodiment, each component is equipped with an independent adjustment seat 14. Operators can independently adjust the horizontal and vertical positions of each component using these adjustment seats 14, according to the different lining specifications, ensuring that the spatial position of each component matches the folding requirements of the current lining specification. The first adjustment plate 143 and the second adjustment plate 144 are equipped with scales. When switching lining specifications, operators can quickly adjust each component to a preset position using these scales, eliminating the need for repeated trial and error, thus shortening changeover time and reducing debugging difficulty. Furthermore, since the adjustment seats 14 of each component are independent, fine-tuning the position of one component does not affect the other components, facilitating precise adjustments on the production line.

[0040] The first closing mechanism 2 and the first pressure plate assembly 41 are mounted on the same adjusting seat 14. Since the first closing mechanism 2 is responsible for folding the fold on one side of the lining upwards, and the first pressure plate assembly 41 is responsible for pressing the fold facing upwards of the lining downwards, the two mechanisms work in tandem during the folding process and their areas of action are adjacent. Mounting them on the same adjusting seat 14 ensures that their relative positional relationship remains consistent during adjustment, avoiding misalignment caused by separate adjustments. In some other embodiments, the first closing mechanism 2 and the first pressure plate assembly 41 can also be mounted on their own independent adjusting seats 14 to obtain greater flexibility in adjustment.

[0041] Reference Figure 2 and Figure 3 In some embodiments, the positioning component 12 includes a first positioning plate 121 and a second positioning plate 122 spaced apart, with a positioning space between the first positioning plate 121 and the second positioning plate 122 forming a positioning space that can accommodate the bottle. The lining conveyor line 11 includes a first conveyor belt 111 and two second conveyor belts 112 arranged side by side on both sides of the first conveyor belt 111; The middle part of the first positioning plate 121 is fixedly connected to the first conveyor belt 111, and the two ends of the second positioning plate 122 are fixedly connected to the two second conveyor belts 112 respectively.

[0042] In this embodiment, after the liner is placed into the positioning component 12, the middle area of ​​the liner falls into the positioning space between the first positioning plate 121 and the second positioning plate 122. Under the constraint of the positioning plate, it folds to form a space that can accommodate the bottle. The rest of the liner rests on the first positioning plate 121 or the second positioning plate 122 to form a fold for subsequent folding.

[0043] The two second conveyor belts 112 are driven by the same drive source, while the first conveyor belt 111 is driven by a separate drive source. Under normal operating conditions, the first conveyor belt 111 and the two second conveyor belts 112 operate synchronously at the same speed. The distance between the first positioning plate 121 and the second positioning plate 122 remains constant, ensuring stable positioning space dimensions. The liner and bottle are reliably clamped and positioned by the first positioning plate 121 and the second positioning plate 122 during transport. When it is necessary to accommodate liner sizes of different specifications, the first conveyor belt 111 and the two second conveyor belts 112 are controlled to move at different speeds, causing relative displacement between the first positioning plate 121 and the second positioning plate 122. This changes the distance of the positioning space along the transport direction. After adjustment, synchronous operation is restored. This differential speed adjustment method does not require disassembly or replacement of the positioning plates; the positioning space dimensions can be adjusted simply by controlling the speed difference between the conveyor belts. The operation is simple and quick, further enhancing the equipment's compatibility with liner sizes of different specifications.

The color box feeding mechanism 30 is located between the color box feeding mechanism 20 and the bottle sealing mechanism 9, and is used to take out the color box from the color box feeding mechanism 20, open it and send it into the bottle sealing mechanism 9.

[0045] In this embodiment, the lining feeding mechanism 5 includes a storage base 51, a lower baffle 52, and an upper baffle 53. The lower baffle 52 and the upper baffle 53 are arranged opposite each other, forming a space for storing the lining. The lining is stacked on the lower baffle 52 in an unfolded state, tilted to the side. There are two lower baffles 52, which are slidably disposed on the storage base 51 and can be adjusted in distance to accommodate linings of different lengths. The upper baffle 53 is disposed on the storage base 51 via a baffle seat 54 and is slidably disposed on the baffle seat 54 in a direction perpendicular to the storage base 51, for limiting the width dimension of the lining from above.

[0046] The lining feeding mechanism 6 includes a support 61 and two suction components 62 slidably mounted on the support 61 along the width direction of the lining conveying mechanism 1. Each suction component 62 includes a spring rod and a suction cup at the end of the spring rod, used to suction the lining from the lining feeding mechanism 5. The lining feeding mechanism 6 also includes a timing belt assembly 63, which includes a driving pulley, a driven pulley, and a timing belt. The support 61 is drive-connected to the driven pulley. The driving pulley and driven pulley are respectively located at both ends of a swing arm 64. The lining feeding mechanism 6 also includes a pull rod 65 rotatably connected to the middle section of the swing arm 64. Driven by the driven pulley, the suction component 62 can rotate around its own axis, used to flip the side-standing lining to a horizontal position after suctioning it. Pull rod 65 drives swing rod 64 to swing, thereby driving suction component 62 to rotate more significantly, so that suction component 62 can swing to inner lining feeding mechanism 5 to suck up inner lining, suck up and flip it, and then swing back to the upper part of inner lining conveying mechanism 1 to put the inner lining into positioning component 12.

[0047] A pre-folding guide assembly 15 is also provided on the lining conveyor line 11. The pre-folding guide assembly 15 is mounted on the frame 13 via an adjusting seat 14. The pre-folding guide assembly 15 includes guide posts 151 and arc-shaped guide plates 152 spaced apart along the width direction of the lining conveyor 1, forming a channel for the lining to pass through. When the lining feeding mechanism 6 places the lining into the positioning assembly 12, the lining enters the positioning space through this channel. Under the constraint of the guide posts 151 and the arc-shaped guide plates 152, it completes preliminary positioning and folding, preventing the lining from warping or springing open due to its own elasticity after placement, ensuring that the lining reliably falls into the positioning assembly 12.

[0048] The bottle material conveying line 7 and the inner liner conveying line 11 adopt the same multi-conveyor belt structure and differential speed adjustment principle, which can adjust the size of the positioning space by the differential speed movement between the conveyor belts, thereby adapting to bottle materials of different widths.

[0049] In this embodiment, the bottle material feeding mechanism 8 uses a spider arm for material handling. The spider arm includes a fixed platform, a movable platform, and multiple parallel arms connecting the fixed platform and the movable platform. One end of each parallel arm is hinged to the fixed platform, and the other end is hinged to the movable platform. Multiple servo motors drive the movement of each parallel arm, thereby causing the movable platform to move in multiple degrees of freedom within space. A clamping or suction device is provided below the movable platform for gripping the bottle material.

[0050] The bottle sealing mechanism 9 includes a color box conveyor line and a corresponding sealing assembly. The color box conveyor line uses synchronous belts arranged vertically to clamp and transport the color boxes, with the openings facing outwards during transport. This vertical clamping method avoids scratching the surface of the color boxes and ensures that the box openings always face outwards, facilitating the subsequent pushing of the bottle material, which is covered with an inner liner, into the color box from the side.

[0051] When the color box is conveyed to the corresponding position of the pusher mechanism 10 in the color box conveyor line, the pusher moves toward the bottle sealing mechanism 9 and pushes the material that has been folded and wrapped on the inner liner conveyor line 11 into the color box through the opening of the color box. After the box is finished, the pusher resets and the color box continues to be conveyed to the sealing assembly downstream.

[0052] The color box feeding mechanism 30 is located between the color box feeding mechanism 20 and the bottle sealing mechanism 9. It is used to take out the color boxes one by one from the color box feeding mechanism 20, open them into a three-dimensional state, and send them into the feeding end of the color box conveyor line. The color box feeding mechanism 20 and the color box feeding mechanism 30 can use existing color box feeding and box opening devices, which are not limited here.

[0053] In some embodiments, the bottle packing equipment with a liner has a first operating mode and a second operating mode; in the first operating mode, the first closing mechanism 2, the lifting rod assembly and the second pressure plate assembly 42 are configured to perform an action to fold a first-size liner; in the second operating mode, the first closing mechanism 2, the guide plate assembly 36, the pressure rod assembly 37 and the first pressure plate assembly 41 are configured to perform an action to fold a second-size liner.

[0054] Reference Figure 5 The first-size liner, when unfolded, forms a cross shape. The central area accommodates the bottle, while the four sides form hinges. When folding, each hinge is folded upwards and pressed together to complete the bottle's coverage. (Refer to...) Figure 6 The second-specification lining unfolds to a different shape than the first-specification lining. The difference in the folding process between the two lining specifications is accommodated by selectively manipulating different components within the equipment.

[0055] In summary, the bottle-packing equipment with liners provided by this invention achieves full automation of the bottle-packing and lining process through the coordinated operation of the lining conveying mechanism 1, the first closing mechanism 2, the second closing mechanism 3, and the third closing mechanism 4, thereby improving production efficiency and the consistency of folding and lining. The equipment is compatible with two different specifications of liners. Folding and lining of the first and second specifications of liners are completed by different component combinations. The first closing mechanism 2 participates in the folding process of both specifications of liners as a common component, while the other components selectively participate in the action according to the lining specifications, allowing the equipment to switch between the two specifications without requiring a complete redesign. Each closing component is independently mounted on the frame 13 via a graduated adjustment seat 14. When switching lining specifications, the operator can quickly adjust each component to the preset position according to the graduations, simplifying the redesign operation and shortening production line downtime. Both the lining conveyor line 11 and the bottle material conveyor line 7 use multiple independently driven conveyor belts, adjusting the size of the positioning space through differential speed movement, further expanding the equipment's adaptability to different material specifications. The equipment also integrates an inner liner feeding mechanism 5, an inner liner feeding mechanism 6, a bottle material feeding mechanism 8, a pushing mechanism 10, a color box feeding mechanism 20, a color box feeding mechanism 30, and a bottle sealing mechanism 9, forming a complete automated production line from inner liner feeding, inner liner folding and wrapping, bottle boxing to sealing.
