Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic packaging machine for cultural and artistic products. Background Technology

[0002] Art and cultural products typically include handicrafts, ornaments, and cultural and creative derivatives. These products come in various forms, often with irregular shapes, and are mostly made of fragile materials such as ceramics, glass, and resin. Therefore, they require high levels of cushioning and protection during the production and packaging process. Currently, packaging for art and cultural products is mostly done manually. Operators first place the product in a cardboard box, then manually fill it with cushioning materials such as foam, bubble wrap, or sponge, and finally seal the box. While some automated packaging equipment can automatically form and seal cardboard boxes, most are designed for products with regular shapes and are less adaptable to irregularly shaped art and cultural products, making it difficult to balance packaging efficiency and consistency.

[0003] The main challenges in automated packaging of cultural and artistic products are as follows: First, the irregular shapes of the products make it difficult to achieve stable positioning using conventional clamping mechanisms, and they are prone to displacement or damage during packaging due to uneven force. Second, the placement and amount of cushioning material need to be adjusted according to the specific shape of the product, and automated equipment struggles to precisely control the adhesion between the cushioning material and the product surface, easily leading to insufficient filling or excessive compression in certain areas. Third, the packaging process involves multiple steps such as cardboard box forming, pad insertion, cushioning medium filling, and box closing, and each step needs to be precisely coordinated. If the level of automation is insufficient, it is difficult to achieve continuous and efficient production while ensuring packaging quality. Therefore, there is an urgent need for an automated packaging machine for cultural and artistic products. Summary of the Invention

[0004] To address at least one of the aforementioned technical shortcomings, the present invention provides an automatic packaging machine for cultural and artistic products, comprising: a conveyor belt, a packaging mechanism located in the middle of the conveyor belt, two symmetrically arranged cardboard box inlets on the top of the packaging mechanism, two symmetrically arranged gasket inlets on the top of the packaging mechanism located inside the cardboard box inlets, a buffer medium injection channel located in the middle of the top of the packaging mechanism, packaging boxes fed in from the cardboard box inlets on both sides of the conveyor belt inside the packaging mechanism, a folding mechanism fixedly connected to the packaging mechanism on the outer side of each packaging box, and a closing mechanism fixedly connected to the packaging mechanism on the outer side of each folding mechanism.

[0005] Furthermore, the top edge of the packaging box has injection notches, and the two injection notches are connected to the bottom end of the buffer medium injection channel.

[0006] Furthermore, the buffer medium injected into the buffer medium injection channel is spherical granular foam balls with a diameter greater than 0.5 cm and less than 1.5 cm.

[0007] Furthermore, the folding mechanism includes a folding channel with a square frame structure, the inner wall of the folding channel is inclined, and inclined guide plates are provided on the inner sides of the four corners of the folding channel.

[0008] Furthermore, the closing mechanism includes a suction cup plate located inside the folding channel for holding the packaging box. A horizontal cylinder is fixedly connected to the outer surface of the suction cup plate. The closing mechanism also includes a rotating cylinder and a vertical cylinder. The vertical cylinder is fixedly connected to the packaging mechanism. The output end of the vertical cylinder is fixedly connected to the rotating cylinder. The rotating end of the rotating cylinder is fixedly connected to the cylinder body of the horizontal cylinder.

[0009] Furthermore, the folding channel is larger on the side closer to the packaging box than on the other side, and the guide plate extends along the inclined inner wall of the folding channel.

[0010] Furthermore, the suction cup plate is evenly distributed with multiple vacuum suction cups, and these vacuum suction cups are connected to an external vacuum source.

[0011] Furthermore, the packaging mechanism is equipped with trays on both sides of the conveyor belt for supporting the packaging boxes, with the upper surface of the trays being lower than the upper surface of the conveyor belt.

[0012] Furthermore, a vertical guide groove is provided at the bottom of the gasket inlet. Beneficial effects

[0013] This invention adapts to irregular product shapes and forms a uniform buffer layer. By setting the buffer medium as spherical granular foam balls with a diameter greater than 0.5 cm and less than 1.5 cm, the spherical granular shape allows the foam balls to adapt to the surface contours of irregular cultural products and fit tightly against the protrusions and depressions of the cultural products, forming a continuous and uniform buffer layer inside the packaging box 6.

[0014] This invention enables precise placement of the pad, avoiding positional deviation. By rotating the packaging box with a cylinder to form an angle, and combined with the vertical guide groove at the bottom of the pad inlet, the sponge pad is precisely placed into the angled gap between the packaging box and the product to be packaged, preventing the sponge pad from shifting during descent.

[0015] This invention achieves precise injection of the buffer medium without interfering with subsequent processes. By opening an injection notch at the top of the packaging box and coordinating with the lifting action of a vertical cylinder, the injection notch and the bottom end of the buffer medium injection channel form a brief connection during injection. This ensures the accuracy of the injection process and allows for rapid separation after injection, avoiding any impact on the subsequent closing action.

[0016] This invention achieves fully automated packaging from folding to sealing. The folding mechanism shapes the flattened packaging box into a square box. The sealing mechanism sequentially moves, rotates, places the foam pad, injects the buffer medium, and finally seals the packaging box. The cultural product to be packaged is held between two packaging boxes 6, and the open ends of the two packaging boxes are joined to form a complete sealed packaging box. The entire process is carried out by a conveyor belt, realizing continuous automated packaging of irregular cultural products from folding, filling to sealing.

[0017] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

[0024] Combined with appendix Figures 1 to 5 An automatic packaging machine for cultural and artistic products includes: a conveyor belt 1, a packaging mechanism 2 in the middle of the conveyor belt 1, two symmetrical cardboard box inlets 3 on the top of the packaging mechanism 2, two symmetrically arranged pad inlets 4 on the top of the packaging mechanism 2 inside the cardboard box inlets 3, a buffer medium injection channel 5 in the middle of the top of the packaging mechanism 2, packaging boxes 6 fed from the cardboard box inlets 3 on both sides of the conveyor belt 1 inside the packaging mechanism 2, a folding mechanism 7 fixedly connected to the packaging mechanism 2 on the outside of the packaging boxes 6, and a closing mechanism 8 fixedly connected to the packaging mechanism 2 on the outside of the folding mechanism 7.

[0025] In practice, the packaging mechanism 2 is fixedly mounted above the middle of the conveyor belt 1, which is used to transport the cultural products to be packaged in a stepping manner.

[0026] Two cardboard box inlets 3 are symmetrically located on the top left and right sides of the packaging mechanism 2, corresponding to the spaces on the left and right sides inside the packaging mechanism 2, and are used to feed the flattened and unfolded packaging cardboard boxes 6 into the packaging mechanism 2.

[0027] Two pad inlets 4 are symmetrically arranged on the top of the packaging mechanism 2 and inside the two cardboard box inlets 3, for guiding the sponge pads to fall to the opening of the packaging cardboard box 6.

[0028] The buffer medium injection channel 5 is located at the top center of the packaging mechanism 2, and its bottom end extends into the interior of the packaging mechanism 2.

[0029] The packaging mechanism 2 has packaging boxes 6 fed in from the cardboard box inlet 3 on the left and right sides of the conveyor belt 1. The opening sides of the two packaging boxes 6 are arranged opposite each other and both face the conveyor belt 1.

[0030] The folding mechanism 7 is fixedly connected to the packaging mechanism 2 and located on the outside of the packaging box 6. The closing mechanism 8 is fixedly connected to the packaging mechanism 2 and located on the outside of the folding mechanism 7. The folding mechanism 7 and the closing mechanism 8 are arranged sequentially in the horizontal direction.

[0031] In use, the cultural products to be packaged are conveyed by conveyor belt 1 to the interior of packaging mechanism 2.

[0032] The flattened and unfolded packaging boxes 6 are fed into the packaging mechanism 2 through the two box inlets 3 respectively. The packaging boxes 6 are positioned on both sides of the conveyor belt 1 inside the packaging mechanism 2, and the open sides of the two packaging boxes 6 are arranged opposite each other.

[0033] The packaging box 6 is folded and formed by the folding mechanism 7 on the outside, so that the packaging box 6 changes from a flat and unfolded state to a square box with the opening facing the conveyor belt 1.

[0034] After being formed, the packaging box 6 moves towards the conveyor belt 1 under the drive of the closing mechanism 8, so that the two packaging boxes 6 are close to the two sides of the cultural product to be packaged.

[0035] The sponge pads are inserted from the two pad inlets 4 respectively, and fall into the opening of the packaging box 6, and are placed between the packaging box 6 and the cultural product to be packaged.

[0036] Two closing mechanisms 8 drive two packaging boxes 6 to press the sponge pads onto the surface of the cultural product to be packaged, so that the cultural product to be packaged is clamped between the two packaging boxes 6.

[0037] The buffer medium is injected into the interior of the two packaging boxes 6 through the buffer medium injection channel 5, filling the remaining space between the packaging boxes 6 and the cultural product to be packaged.

[0038] After injection, the two closing mechanisms 8 drive the two packaging boxes 6 to approach each other and close, so that the open ends of the two packaging boxes 6 are joined to form a closed complete packaging box.

[0039] After the lid is closed, the two closing mechanisms 8 release the packaging box 6, and the complete packaging box falls onto the conveyor belt 1, which then sends it out of the packaging mechanism 2.

[0040] Furthermore, the top edge of the packaging box 6 is provided with an injection notch 61, and the two injection notches 61 are connected to the bottom end of the buffer medium injection channel 5.

[0041] In practice, after the packaging box 6 is folded and clamped to the packaging product, the buffer medium injection stage begins.

[0042] The injection notches 61 on the top of the two packaging boxes 6 face upwards. The vertical cylinder 84 in the closing mechanism 8 retracts upwards, causing the packaging boxes 6 to rise as a whole until the injection notches 61 on the top of the two packaging boxes 6 simultaneously align with the bottom end of the buffer medium injection channel 5 in the middle of the top of the packaging mechanism 2, forming a through injection path.

[0043] The buffer medium injection channel 5 is activated, and spherical foam balls are injected into the packaging box 6 through the injection notch 61. The foam balls enter the cavity of the packaging box 6 along the injection notch 61, filling the remaining space between the packaging box 6 and the cultural product to be packaged.

[0044] After injection, the vertical cylinder 84 extends downward, causing the packaging box 6 to descend as a whole, separating the injection notch 61 from the bottom of the buffer medium injection channel 5, and the packaging box 6 returns to the standby position before closing.

[0045] By setting the injection notch 61, the buffer medium can be accurately injected when the packaging carton 6 is in a clamped state. The injection notch 61 and the bottom end of the buffer medium injection channel 5 form a brief docking during injection, which not only ensures the accuracy of the injection process, but also quickly separates after injection.

[0046] Furthermore, the buffer medium injected into the buffer medium injection channel 5 is spherical granular foam balls with a diameter greater than 0.5 cm and less than 1.5 cm.

[0047] In practice, during the buffer medium injection stage, once the injection notches 61 at the top of the two packaging boxes 6 are aligned with the bottom of the buffer medium injection channel 5, the buffer medium injection channel 5 initiates the injection operation.

[0048] The buffer medium stored inside the buffer medium injection channel 5 is spherical granular foam balls with a diameter greater than 0.5 cm and less than 1.5 cm. During injection, the spherical granular foam balls are injected along the buffer medium injection channel 5 under the action of gravity and airflow, and enter the packaging carton 6 through the injection notch 61. The airflow is discharged from the gap.

[0049] Because the foam balls are spherical granules with a diameter limited to between 0.5 cm and 1.5 cm, they are less likely to get stuck during the flow process and can smoothly pass through the buffer medium injection channel 5 and injection notch 61, and evenly disperse into the cavity of the packaging box 6.

[0050] After the foam balls enter the packaging box 6, they naturally accumulate under the influence of gravity, filling the remaining space between the inner wall of the packaging box 6 and the outer surface of the cultural product to be packaged. The spherical and granular shape of the foam balls allows them to adapt to the irregular surface contours of the cultural product, closely adhering to the protrusions and depressions of the cultural product, forming a continuous and uniform cushioning layer inside the packaging box 6.

[0051] After injection, the foam balls completely fill the gaps inside the packaging box 6. During subsequent closing and transportation, foam balls with a diameter greater than 0.5 cm are not easy to leak out from the gaps in the packaging box 6, while foam balls with a diameter less than 1.5 cm ensure sufficient fluidity and filling density, so that the cushioning medium can be evenly distributed and avoid local insufficient filling.

[0052] Furthermore, the folding mechanism 7 includes a folding channel 71 with a square frame structure. The inner wall of the folding channel 71 is inclined, and inclined guide plates 72 are provided on the inner sides of the four corners of the folding channel 71.

[0053] In practice, when folding the box, the horizontal cylinder 82 retracts, pulling the suction cup plate 81 away from the conveyor belt 1. The suction cup plate 81 uses a vacuum suction cup to adhere and fix the flattened, unfolded packaging box 6, driving the packaging box 6 into the folding channel 71.

[0054] The folding channel 71 has a square frame structure, with the side closest to the packaging box 6 being larger than the other side, and its inner wall is inclined, gradually narrowing from the inlet to the outlet. As the packaging box 6 enters the folding channel 71, its four sides successively contact the inclined inner wall of the folding channel 71, and are squeezed inward by the inner wall, causing it to bend inward.

[0055] Meanwhile, the guide plates 72 set on the inner sides of the four corners of the folding channel 71 are inclined. During the movement of the packaging box 6, the guide plates 72 contact the four corners of the packaging box 6 respectively and fold the corners inward.

[0056] When the packaging box 6 is fully inserted into the folding channel 71, the packaging box 6 is formed from a flat and unfolded state into a square box with the opening facing the conveyor belt 1. The formed packaging box 6 is held and fixed inside the folding channel 71 by the suction cup plate 81.

[0057] The packaging cardboard box 6 has creases from pre-compression.

[0058] Furthermore, the closing mechanism 8 includes a suction cup plate 81 located inside the folding channel 71 for holding the packaging carton 6. A horizontal cylinder 82 is fixedly connected to the outer surface of the suction cup plate 81. The closing mechanism 8 also includes a rotating cylinder 83 and a vertical cylinder 84. The vertical cylinder 84 is fixedly connected to the packaging mechanism 2. The output end of the vertical cylinder 84 is fixedly connected to the rotating cylinder 83. The rotating end of the rotating cylinder 83 is fixedly connected to the cylinder body of the horizontal cylinder 82.

[0059] In practice, an external vacuum source is activated, and multiple vacuum suction cups evenly distributed on the suction cup plate 81 generate negative pressure, adsorbing and fixing the flattened, unfolded packaging box 6 onto the surface of the suction cup plate 81. The horizontal cylinder 82 retracts, moving the suction cup plate 81 and the packaging box 6 horizontally away from the conveyor belt 1, allowing the packaging box 6 to enter the folding channel 71. During passage through the folding channel 71, the inclined inner wall of the folding channel 71 bends the four sides of the packaging box 6 inwards, and the guide plates 72 on the inner sides of the four corners fold the four corners of the packaging box 6 inwards, transforming the packaging box 6 from a flat, unfolded state into a square box with its opening facing the conveyor belt 1. After folding, the packaging box 6 is fully inside the folding channel 71 and held and fixed by the suction cup plate 81.

[0060] Horizontal cylinder 82 extends, pushing suction cup plate 81 and the formed packaging box 6 towards conveyor belt 1, bringing the packaging box 6 closer to the cultural product to be packaged. Rotary cylinder 83 starts, its rotating end driving horizontal cylinder 82 and suction cup plate 81 to rotate at a certain angle, so that the opening plane of packaging box 6 forms an angle with the corresponding side of the cultural product to be packaged. A sponge pad is inserted from pad inlet 4 and falls along the vertical guide groove into the angled gap between packaging box 6 and the cultural product to be packaged. Then, rotary cylinder 83 rotates in the opposite direction to reset, while horizontal cylinder 82 continues to extend, causing packaging box 6 to press the sponge pad against the surface of the cultural product to be packaged.

[0061] After the sponge pad is placed, with the horizontal cylinder 82 extended, the vertical cylinder 84 retracts upward, and its output end drives the rotating cylinder 83, the horizontal cylinder 82, the suction cup plate 81, and the packaging box 6 to rise as a whole. After the buffer medium is injected, the vertical cylinder 84 extends downward, causing the packaging box 6 to descend to its initial height. The horizontal cylinder 82 continues to extend, bringing the open ends of the two packaging boxes 6 closer together and closing them. After closing, the vacuum suction cup releases the vacuum, the horizontal cylinder 82 retracts and resets, the packaging box 6 detaches from the suction cup plate 81, and the closed, complete packaging box falls onto the conveyor belt 1.

[0062] Furthermore, the folding channel 71 has a larger dimension on the side closest to the packaging box 6 than on the other side, and the guide plate 72 extends along the inclined inner wall of the folding channel 71.

[0063] In practice, when folding the box, the horizontal cylinder 82 retracts, causing the suction cup plate 81 and the flattened, unfolded packaging box 6 attached to the suction cup plate 81 to move into the folding channel 71.

[0064] The folding channel 71 has a larger dimension on the side closest to the packaging box 6 than on the other side, forming an inclined inner wall that gradually narrows from the inlet to the outlet. As the packaging box 6 enters the folding channel 71, its four sides successively contact the inclined inner wall and are gradually bent inward by the pressure from the inner wall.

[0065] The guide plate 72 extends along the inclined inner wall of the folding channel 71. During the movement of the packaging box 6, the guide plate 72 maintains continuous contact with the four corners of the packaging box 6, folding the corners inward.

[0066] When the packaging box 6 is fully inserted into the folding channel 71, the packaging box 6 is formed from a flat, unfolded state into a square box with its opening facing the conveyor belt 1.

[0067] Furthermore, multiple vacuum suction cups are evenly distributed on the suction cup plate 81, and these vacuum suction cups are connected to an external vacuum source.

[0068] In practice, multiple vacuum suction cups are evenly distributed on the suction cup plate 81, and each vacuum suction cup is connected to an external vacuum source through a pipe. When folding the box, the external vacuum source is activated, and the multiple vacuum suction cups simultaneously generate negative pressure, adsorbing and fixing the flattened and unfolded packaging box 6 to the surface of the suction cup plate 81. During the folding, moving, and closing processes, the vacuum suction cups maintain negative pressure, keeping the packaging box 6 always relatively fixed to the suction cup plate 81. After closing, the external vacuum source is turned off, the vacuum suction cups release the vacuum, and the packaging box 6 detaches from the suction cup plate 81 and falls onto the conveyor belt 1.

[0069] Furthermore, the packaging mechanism 2 is equipped with trays on both sides of the conveyor belt 1 for supporting the packaging boxes 6, and the upper surface of the trays is lower than the upper surface of the conveyor belt 1.

[0070] In practical implementation, the packaging mechanism 2 has trays on both sides of the conveyor belt 1 inside. The trays are used to support the packaging boxes 6 fed in from the box inlet 3. The upper surface of the tray is lower than the upper surface of the conveyor belt 1. When the packaging box 6 falls into the tray, the bottom of the packaging box 6 will be lower than the bottom of the cultural product to be packaged on the conveyor belt 1, so that the center of the opening side of the packaging box 6 corresponds to the center of the cultural product to be packaged, and so that the cultural product to be packaged is located as close as possible to the center of the vertical direction of the packaging box 6.

[0071] Furthermore, a vertical guide groove is provided at the bottom of the gasket inlet 4.

[0072] In practice, the bottom of the pad inlet 4 is provided with a vertical guide groove, which extends downward to the opening of the packaging box 6. When the sponge pad is inserted from the pad inlet 4, it falls vertically along the vertical guide groove. The inner wall of the vertical guide groove restricts the falling path of the sponge pad, ensuring that it falls precisely into the angled gap between the packaging box 6 and the product to be packaged, thus preventing the sponge pad from shifting during its descent.
