[0054] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of the present invention.

[0056] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0057] Furthermore, in the embodiments of this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of the embodiments of this invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0059] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope required by the embodiments of the present invention.

[0060] In industrial production, products often need to be packaged for ease of transportation and protection. However, incoming packaging boxes are usually flat cardboard boards, which typically need to be unfolded into a box shape. Existing automatic box-folding equipment can generally only unfold the cardboard boards, and then the product must be manually placed in and sealed. This involves many manual steps, is time-consuming and labor-intensive, and is not conducive to improving packaging efficiency.

[0061] In view of this, embodiments of the present invention provide a paper box forming and packaging equipment. Through the coordinated operation of the box opening mechanism, the product pushing mechanism and the folding mechanism, a series of processes such as paper box forming, target product packaging and paper box sealing can be automated, reducing the amount of manual intervention and effectively improving packaging efficiency.

[0062] It should be noted that in the following embodiments, the paper box forming and packaging equipment is applied to tubular paper boxes. This means the paper box includes a box body, dustproof wings, and a lid connected to the box body. The box body includes four interconnected plates: a first plate, a second plate, a third plate, and a fourth plate. The first and third plates are positioned opposite each other, as are the second and fourth plates. The first, second, third, and fourth plates form a cavity with openings on both sides, i.e., the cavity has a first opening and a second opening. Two dustproof wings are provided at each of the first and second openings, respectively, and are positioned opposite each other. One dustproof wing is connected to the first plate, and the other is connected to the third plate. A lid is provided at each of the first and second openings. The lid includes a lid body and a tongue connected to the lid body, and the lid body is connected to the second plate. Therefore, in the following embodiments, the opening mechanism unfolds the box body, i.e., unfolds the first, second, third, and fourth plates into a cavity with openings on both sides. The folding mechanism first folds the dust flap, then folds the lid to seal the box. Specifically, the first folding component in the folding mechanism folds the dust flap, the folding edge module in the second folding component folds the lid, and the tongue module in the second folding component inserts the tongue into the cavity through the opening to seal the box. It can be understood that a separate folding mechanism can be provided for the first and second openings to achieve simultaneous folding on both sides. For ease of description, the following embodiments will use the folding of the dust flap and lid on the same side as an example.

[0063] In addition, in the following embodiments, along the conveying direction of the box-shaped paper box, there are sequentially an opening position, a product pushing position, and a finished product ejection position.

[0064] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0065] like Figure 1 As shown in the figure, an embodiment of the present invention provides a paper box forming and packaging equipment, which includes:

[0066] The box-opening mechanism 100 is used to unfold the flat cardboard board into a box-shaped cardboard box 000;

[0067] The product pushing mechanism 200, located on one side of the box opening mechanism 100, is used to push the target product into the interior of the cardboard box 000; and,

[0068] The folding mechanism 300 is located on the side of the product pushing mechanism 200 opposite to the box mechanism 100, and is used to fold the cardboard box 000 into which the target product has been pushed to encapsulate the target product inside the cardboard box 000.

[0069] In this embodiment, the box-opening mechanism 100 folds and unfolds the flat cardboard board to form a box-shaped cardboard box 000. Then, the product-pushing mechanism 200 pushes the target product (i.e., the product to be packaged) into the cardboard box 000, thus packaging the target product. Finally, the folding mechanism 300 folds the cardboard box 000 containing the target product, sealing the box 000. The technical solution proposed in this embodiment, through the coordinated operation of the box-opening mechanism 100, the product-pushing mechanism 200, and the folding mechanism 300, automates a series of processes, including the forming of the cardboard box 000, the packaging of the target product, and the sealing of the cardboard box 000, reducing manual intervention and effectively improving packaging efficiency.

[0070] For example, refer to Figure 2 and Figure 14 In one embodiment of the present invention, the box-opening mechanism 100 includes:

[0071] Suction cup 110 is used to pick up flat cardboard boxes and initially unfold them; and

[0072] The orthopedic member 120 is movably disposed on one side of the suction cup 110 and is used to abut against the initially unfolded cardboard board to unfold the cardboard board into cardboard box 000.

[0073] Specifically, the paper box 000 forming packaging mechanism includes an opening mechanism 100, which unfolds a flat paper box board to form a box-shaped paper box 000. The opening mechanism 100 includes a suction cup 110 and a shaping member 120. The suction cup 110 is used to pick up the paper box board at the opening position. During the picking process, the paper box board can be initially unfolded, that is, the first body plate 011, the second body plate 012, the third body plate, and the fourth body plate unfold into a cavity with openings on both sides. In one embodiment, multiple suction cups 110 can be provided, and the multiple suction cups 110 are arranged in an array to pick up different positions of the paper box board, improving the effect of the initial unfolding of the paper box board. As an optional approach, since the surface area of ​​the first body plate 011 is smaller than the surface area of ​​the second body plate 012, the suction cup 110 can pick up either the second body plate 012 or the fourth body plate of the paper box board, which is more conducive to the initial unfolding of the paper box board.

[0074] However, the initially unfolded box 010 is relatively tilted, making it inconvenient to push in the target product. Therefore, the opening mechanism 100 also includes a corrective element 120, which is located on one side of the suction cup 110. This corrective element 120 can correct the initially unfolded box 000, causing it to unfold into a rectangular box 010, facilitating the entry of the target product into the cavity through the opening. Alternatively, the corrective element 120 can be a cylinder or a telescopic rod, located on one side of the suction cup 110. After the suction cup 110 picks up the box plate and initially unfolds it, the cylinder or telescopic rod extends, abutting against the initially unfolded box 000 until it changes from a tilted state to a rectangular state, and maintains this abutment for a predetermined time to prevent the box 000 from returning to its tilted state. Alternatively, the corrective element 120 abuts against the first plate 011 or the third plate of the box 000.

[0075] For example, refer to Figure 2 In one embodiment of the present invention, the box opening mechanism 100 further includes: a lifting component 130, which is drivenly connected to the suction cup 110; and / or, the box opening mechanism 100 further includes a transverse module 140, which is connected to both the suction cup 110 and the orthopedic member 120, and the paper box 000 is conveyed toward the product pushing mechanism 200 through the transverse module 140.

[0076] In this embodiment, the box-opening mechanism 100 further includes a lifting assembly 130. The suction cup 110 and the orthotic member 120 are both connected to the lifting assembly 130. The suction cup 110 can move towards the cardboard box under the drive of the lifting assembly 130 to pick up the cardboard box, or the suction cup 110 can move away from the cardboard box under the drive of the lifting assembly 130 to transfer the picked-up cardboard box. Alternatively, the lifting assembly 130 can be a cylinder, a telescopic rod, etc.

[0077] In another embodiment, refer to Figure 2 The box opening mechanism 100 also includes a horizontal movement module 140, on which a lifting component 130 is mounted and can move horizontally under the drive of the horizontal movement module 140. It can be understood that the horizontal movement module 140 can drive the lifting component 130 and the suction cup 110 to move in the horizontal direction, facilitating the transport of the cardboard box 000 from the box opening position to the product pushing position.

[0078] For example, refer to Figure 1 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the paper box forming and packaging equipment further includes a hopper 400, which is used to stack paper box boards, and a suction cup 110 is used to pick up the bottommost paper box board in the hopper 400.

[0079] In this embodiment, a hopper 400 is provided for convenient material storage. Cardboard boxes are stacked inside the hopper 400. A discharge port is provided at the bottom of the hopper. The suction cup 110 can pick up the bottommost cardboard box in the hopper 400 and remove it from the hopper 400 through the discharge port. In one embodiment, refer to Figure 4 A support plate 420 is provided at the discharge port, which supports the edge of the cardboard board and provides support for the cardboard board inside the hopper 400. When the suction cup 110 picks up the bottom cardboard board, the cardboard board picked up by the suction cup 110 will first deform due to the obstruction of the support plate 420, and then leave the hopper 400 from the discharge port. During this process, the flat cardboard board initially unfolds into a box-shaped cardboard box 000.

[0080] For example, refer to Figure 3 In one embodiment of the present invention, a door 410 is provided on the side of the hopper 400. It is understood that the hopper 400 can be replenished with cardboard trays by opening the door 410. Furthermore, the door 410 being located on the side of the hopper 400 improves the convenience of replenishing cardboard trays and prevents the cardboard trays from tilting due to top replenishment. As an optional method, two hoppers 400 are provided. The suction cup 110 first retrieves material from one hopper 400. When that hopper 400 is empty, it then retrieves material from the other hopper. Simultaneously, the empty hopper 400 can be replenished, thus further improving work efficiency.

[0081] In one embodiment, a material height detection sensor is installed inside the hopper 400 to detect the height of the cardboard boxes within the hopper 400. Specifically, the material height detection sensor can monitor the height of all cardboard boxes within the hopper 400. When the detected height is lower than a predetermined value, it indicates that the number of cardboard boxes in the hopper 400 is insufficient, and new cardboard boxes need to be replenished promptly. This allows for timely detection of insufficient cardboard boxes in the hopper 400 and timely and effective replenishment of new cardboard boxes.

[0082] For example, refer to Figure 5 In one embodiment of the present invention, the product pushing mechanism 200 includes:

[0083] Guide member 210 has a guide cavity, the cross-sectional dimension of which is smaller than the cross-sectional dimension of cardboard box 000 to guide the target product; and

[0084] The pusher 220 is movably located on one side of the guide 210 and is used to abut against the target product to push the target product into the interior of the cardboard box 000 through the guide cavity.

[0085] In this embodiment, the product pushing mechanism 200 includes a guide 210 and a pusher 220. When the carton 000 is conveyed from the opening position to the product pushing position under the drive of the transverse module 140, the guide cavity of the guide cavity is aligned with the opening of the carton 000's cavity. The pusher 220 operates, abutting against the target product, and pushes the target product into the cavity after being guided by the guide 210. It can be understood that the guide 210 is used to guide and position the target product, so that the target product can be accurately pushed into the cavity. As an optional method, the cross-sectional dimension of the guide cavity is smaller than the cross-sectional dimension of the carton 000. In this way, when the guide cavity is aligned with the opening of the cavity, the target product falls completely within the range of the opening, which can improve the accuracy of pushing the target product into the cavity.

[0086] As an optional configuration, the cardboard box forming and packaging equipment also includes a worktable, with guides 210 and pushers 220 disposed on the worktable. (See reference...) Figure 5 The guide member 210 includes two guide plates 211 that are positioned opposite each other and spaced apart. The two guide plates 211 extend towards each other at their ends facing the cardboard box 000, forming a guide cavity between them. The inner diameter of the guide cavity near the cardboard box 000 is smaller, gradually pushing the target product into the cavity of the cardboard box 000 during the pushing process. In other embodiments, the guide member 210 also includes a guide cover 212, which is disposed on the side of the guide plate 211 away from the worktable. The end of the guide cover 212 near the cardboard box 000 extends towards the worktable, thus ensuring that the edge of the target product is inside the edge of the cavity of the cardboard box 000.

[0087] In one embodiment, the pusher 220 may be a cylinder or a telescopic rod, etc., which is not limited here.

[0088] For example, refer to Figure 5 In one embodiment of the present invention, the product pushing mechanism 200 further includes:

[0089] Positioning member 230 is movably located on the other side of guide member 210. Positioning member 230 is used to extend into the interior of paper box 000 and cooperate with push member 220 to abut against the opposite sides of the target product to position the target product inside paper box 000.

[0090] Since the unfolded cardboard box 000 has a first opening and a second opening, a positioning element 230 is provided to prevent the target product from being pushed in through the first opening and then pushed out through the second opening. Before the target product is pushed, the positioning element 230 operates, extending into the cavity of the cardboard box 000 through the second opening. Then, the pushing element 220 operates, pushing the target product into the cavity of the cardboard box 000 through the first opening until the target product contacts the positioning element 230. At this point, the target product is pushed into place, and the pushing element 220 and the positioning element 230 return to their original positions. In other words, through the cooperation of the positioning element 230 and the pushing element 220, the target product can be pushed into a predetermined position within the cavity of the cardboard box 000, improving the positioning accuracy of the target product within the cardboard box 000.

[0091] In one embodiment, refer to Figure 5 The product pushing mechanism 200 also includes a first sensor 240, which is disposed within the guide member 210 and is used to detect whether the target product is in place. When the target product is detected to be in place, the pushing member 220 and the positioning member 230 begin to operate.

[0092] In another embodiment, refer to Figure 5 The product feeding mechanism 200 also includes a second sensor 250, disposed on the side of the guide 210 facing the pusher 220, for detecting the pusher 220. If the second sensor 250 detects the pusher 220, the target product has been pushed into the predetermined position of the paper tray 000. If the second sensor 250 does not detect the pusher 220, the target product has not been pushed into the predetermined position of the paper tray 000.

[0093] In other embodiments, refer to Figure 5 The product pushing mechanism 200 also includes a third sensor 260, located on the side of the guide 210 facing the cardboard box 000, for detecting bubble wrap. It is understood that bubble wrap is typically placed in the cardboard box 000 to better protect the target product, cushioning external forces and preventing damage. After the target product is pushed into the predetermined position in the cardboard box 000, if the third sensor 260 detects bubble wrap, the bubble wrap has already popped out of the cardboard box 000 and needs to be re-inserted; if the third sensor 260 does not detect bubble wrap, both the bubble wrap and the target product are inside the cardboard box 000.

[0094] For example, refer to Figure 1 and Figure 6 In one embodiment of the present invention, the paper box forming and packaging equipment further includes a translation module 510 and a clamping module 520 connected to the translation module 510. The paper box 000 is conveyed from the product pushing mechanism 200 toward the folding mechanism 300 through the translation module 510 and the clamping module 520.

[0095] To further improve work efficiency, the cardboard box forming and packaging equipment also includes a translation module 510 and a clamping module 520. Understandably, after the unfolded cardboard box 000 is conveyed to the product pushing position under the drive of the translation module 140, the suction cup 110 releases the cardboard box 000, and the clamping module 520 clamps the cardboard box 000, allowing it to move horizontally under the drive of the translation module 510. The suction cup 110, having released the cardboard box 000, returns to its original position under the drive of the translation module 140, picking up and unfolding the next cardboard box 000. This ensures the continuity of the unfolding of the cardboard box 000 and the loading of products, effectively improving work efficiency.

[0096] In one embodiment, refer to Figure 6 The clamping module 520 includes a lifting unit 521, a clamping cylinder 522, and grippers 523. The lifting unit 521 is mounted on the translation module 510 and can move horizontally under the drive of the translation module 510. The clamping cylinder 522 is mounted on the lifting unit 521 and can move towards or away from the paper box 000 under the drive of the lifting unit 521. At least two sets of grippers 523 are arranged opposite each other, and the two sets of grippers 523 are connected by the clamping cylinder 522. They can move closer to or further away from each other under the drive of the clamping cylinder 522 to adjust the opening angle and clamping force of the two sets of grippers 523, better clamping the opposite sides of the paper box 000, improving the reliability and stability of clamping the paper box 000, and preventing deformation of the paper box 000.

[0097] For example, refer to Figure 7 and Figure 14 In one embodiment of the present invention, the cardboard box 000 has a box body 010, a dustproof wing 030 connected to the box body 010, and a box cover 020 disposed adjacent to the dustproof wing 030. The folding mechanism 300 includes:

[0098] The first folding assembly 310 is located on the side of the product pushing mechanism 200 opposite to the box-opening mechanism 100, and is used to bend the dustproof wing 030; and

[0099] The second folding component is located on the side of the first folding component 310 away from the product pushing mechanism 200, and is used to bend the box lid 020.

[0100] In this embodiment, the folding mechanism 300 includes a first folding component 310 and a second folding component arranged side by side. The first folding component 310 is used to bend the dustproof wing 030, and the second folding component is used to bend the box lid 020. It is understood that the arrangement of the first folding component 310 and the second folding component makes the structure more compact and allows for separate bending of the dustproof wing 030 and the box lid 020, meaning that bending of the dustproof wing 030 and the box lid 020 can be performed simultaneously, ensuring the continuity of bending of the front and rear cartons 000 and further improving work efficiency.

[0101] For example, refer to Figure 7 and Figure 8 In one embodiment of the present invention, the first folding component 310 includes:

[0102] The folding ear rotating block 311 is rotatably disposed on the side of the product pushing mechanism 200 away from the box mechanism 100. The folding ear rotating block 311 has a first folding ear portion 3111 and a second folding ear portion 3112 that are spaced apart. The first folding ear portion 3111 and the second folding ear portion 3112 rotate synchronously with the folding ear rotating block 311. The first folding ear portion 3111 rotates along the circumference of a first virtual circle, and the second folding ear portion 3112 rotates along the circumference of a second virtual circle. The radius of the first virtual circle is smaller than the radius of the second virtual circle.

[0103] In this embodiment, the first folding assembly 310 includes a rotating lug block 311, which is rotatably configured. By rotating the lug block 311, the dustproof wing 030 of the cardboard box 000 can be brought into contact with the side facing away from the opening. As the lug block 311 continues to rotate, the dustproof wing 030 can rotate synchronously with it, thereby bending the dustproof wing 030 approximately 90 degrees towards the opening. Furthermore, the lug block 311 has a first lug portion 3111 and a second lug portion 3112 spaced apart. Since the radius of the first virtual circle is smaller than the radius of the second virtual circle, during the rotation of the lug block 311, the first lug portion 3111, rotating along the first virtual circle, firstly contacts the dustproof wing 030 and initially bends it. Then, the first lug portion 3111 gradually separates from the dustproof wing 030, while the second lug portion 3112 gradually contacts the dustproof wing 030 and continues to bend it. Understandably, if only the first folding lug 3111 is used to bend the dustproof wing 030, it is too short to fold the dustproof wing 030 to 90°, thus failing to complete the folding action. If only the second folding lug 3112 is used, it is too long, closer to the dustproof wing 030, and has less clearance, making it easy to damage the dustproof wing 030. Therefore, in this embodiment, the cooperation of the first folding lug 3111 and the second folding lug 3112 can improve the bending accuracy of the dustproof wing 030 and prevent damage to the dustproof wing 030.

[0104] In one embodiment, refer to Figure 7 The first folding assembly 310 also includes a first power source 313, which is drivenly connected to the folding lug rotating block 311 to drive the folding lug rotating block 311 to rotate. Specifically, the first power source 313 can effectively drive the folding lug rotating block 311 to rotate. As an option, the first power source 313 can be a rotary cylinder or a motor, which is not limited here.

[0105] As an optional approach, to achieve simultaneous bending of the two dustproof wings 030 on the same side of the opening, two folding lugs 311 can be provided along the forward direction of the cardboard box 000. Of course, in other embodiments, the first folding assembly 310 also includes a folding lug bend 312, which is located at the front end of the folding lugs 311 in the direction of movement of the cardboard box 000. It is understood that during the movement of the cardboard box 000, the folding lugs 312 will abut against the side of the dustproof wings 030 at the front end of the cardboard box 000 facing away from the opening. As the cardboard box 000 continues to move, the folding lugs 312 will bend the dustproof wings 030 towards the opening until the dustproof wings 030 are bent at 90 degrees. Then the cardboard box 000 stops moving, and after the folding lugs 311 bend the dustproof wings 030 at the rear end of the cardboard box 000, the cardboard box 000 moves again. In other words, by setting the folding ear oblique block 312 in this embodiment, the dustproof wing 030 at the front end of the cardboard box 000 can be bent during the movement of the cardboard box 000, which can reduce the number of structural components and further improve the compactness of the structure. As an optional method, the side of the folding ear oblique block 312 facing the opening is flush with the opening, thus ensuring the bending accuracy of the dustproof wing 030 at the front end of the cardboard box 000.

[0106] For example, refer to Figures 9-11 as well as Figure 14 In one embodiment of the present invention, the lid 020 includes an adjacent lid body 021 and a lid tongue 022, the lid body 021 being connected to the box body 010, and the second folding assembly including:

[0107] A folding module 321 is located on the side of the first folding assembly 310 opposite to the product pushing mechanism 200, and is used to bend the cover body 021 and the box tongue 022; and

[0108] The tongue module 322 is located on the side of the folding module 321 away from the first folding component 310, and is used to insert the bent box tongue 022 into the inside of the box body 010.

[0109] In this embodiment, the second folding assembly includes a folding edge module 321 and a tongue insertion module 322. The folding edge module 321 is used to bend the lid body 021 and the tongue 022 of the cardboard box 000, and the tongue insertion module 322 is used to insert the bent tongue 022 into the interior of the cardboard box 000 through the opening to achieve sealing. It is understood that before inserting the tongue 022 into the interior of the cardboard box 000, the folding edge module 321 first performs a preliminary bend on the lid body 021 and the tongue 022, thus improving the accuracy of the tongue 022's insertion into the cardboard box 000.

[0110] For example, refer to Figure 9 and Figure 10 In one embodiment of the present invention, the folding module 321 includes:

[0111] The upper and lower pressure blocks 3211 are movably disposed on the side of the first folding assembly 310 opposite to the product pushing mechanism 200, and are used to abut against the cover body 021 to bend the cover body 021 in the vertical direction; and

[0112] The left and right push blocks 3212 are movably located on one side of the upper and lower pressure blocks 3211 and are used to abut against the box tongue 022 to bend the box tongue 022 in the left and right directions.

[0113] Specifically, the folding module 321 includes upper and lower pressing blocks 3211 and left and right pushing blocks 3212. The upper and lower pressing blocks 3211 are used to bend the cover body 021 in the vertical direction, and the left and right pushing blocks 3212 are used to bend the box tongue 022 in the horizontal direction. It can be understood that when the cardboard box 000 is in position, the upper and lower pressing blocks 3211 first move towards the cover body 021 and abut against the side of the cover body 021 facing away from the opening. The upper and lower pressing blocks 3211 continue to move, causing the cover body 021 to bend towards the opening. After the cover body 021 is bent to a predetermined degree, the left and right pushing blocks 3212 move towards the opening and abut against the side of the box tongue 022 facing away from the opening. The left and right pushing blocks 3212 continue to move, causing the box tongue 022 to bend towards the opening until the box tongue 022 is bent into place.

[0114] As an alternative, the extended side of the left and right push blocks 3212 extends toward the side of the box tongue 022 into the interior of the paper box 000 and is spaced apart from the inner wall of the box body 010. This allows the box tongue 022 to be bent into place, making it easy for the box tongue 022 to be inserted into the interior of the paper box 000.

[0115] In one embodiment, refer to Figure 9 and Figure 10 The folding module 321 also includes a second power source 3213 and a third power source 3214. The second power source 3213 is driven and connected to the upper and lower pressure blocks 3211, and the third power source 3214 is driven and connected to the left and right push blocks 3212. The second power source 3213 and the third power source 3214 are either telescopic cylinders or telescopic rods, which are not limited here.

[0116] For example, refer to Figure 11 and Figure 12 In one embodiment of the present invention, the tongue module 322 includes:

[0117] The limiting block 3221 is located on the side of the folding module 321 away from the first folding component 310. The limiting block 3221 protrudes from the inner wall of the box body 010 and abuts against the box tongue 022 on the side facing the box tongue 022.

[0118] The side push block 3222 is located on the side of the limiting block 3221 facing the box tongue 022 and is slidably connected to the limiting block 3221. The side push block 3222 is used to abut against the box cover 020 to drive the box cover 020 to move toward the box body 010 so that the box tongue 022 is inserted into the inside of the box body 010.

[0119] Specifically, the tongue module 322 includes a limiting block 3221 and a side push block 3222. The limiting block 3221 abuts against the side of the tongue 022 away from the cover body 021 to limit the tongue 022. The side push block 3222 is located on the side of the limiting block 3221 facing the tongue 022 and is used to push the cover body 021 and the tongue 022 into the interior of the cardboard box 000. It can be understood that when the cardboard box 000 is in place, the limiting block 3221 abuts against the side of the tongue 022 away from the cover body 021, the side push block 3222 moves toward the cardboard box 000 and abuts against the cover body 021, and the side push block 3222 continues to move toward the cardboard box 000 until the tongue 022 is inserted into the interior of the cardboard box 000.

[0120] In other embodiments, refer to Figure 11 The tongue module 322 also includes a fourth power source 3223, which is drivenly connected to the side push block 3222 to drive the side push block 3222 to move toward or away from the cardboard box 000. The fourth power source 3223 is either a side push cylinder or a telescopic rod, which is not limited here.

[0121] As an alternative, the side push block 3222 abuts against the connection between the cover body 021 and the lid tongue 022, thus providing effective pushing force. Of course, in other embodiments, the side push block 3222 may first abut against the aforementioned connection and then against the cover body 021, which is not limited here.

[0122] In one embodiment, the side of the limiting block 3221 facing the tongue 022 protrudes from the inner wall of the box body 010. That is, the extended surface of the limiting block 3221 facing the tongue 022 extends into the interior of the cardboard box 000 and is spaced apart from the inner wall of the box body 010. This effectively limits the tongue 022 to the inside of the opening, improving the success rate of tongue insertion. Since the cardboard box 000 has two lids 020, the following two scenarios are possible:

[0123] (i) One of the two lids 020 is connected to the second body plate 012, that is, the lid body 021 of the lid 020 is connected to the second body plate 012, and the lid tongue 022 of the lid 020 is inserted into the interior of the cardboard box 000 on the side near the fourth body plate. At this time, the limiting block 3221 protrudes from the inner wall of the fourth body plate. It can be understood that the minimum vertical distance between the fourth body plate and the lid tongue 022 is greater than the minimum vertical distance between the limiting block 3221 and the lid tongue 022. That is, the side of the limiting block 3221 facing the lid tongue 022 is located on the side of the fourth body plate facing the second body plate 012, that is, the extended surface of the side of the limiting block 3221 facing the lid tongue 022 extends into the cavity of the cardboard box 000 and is spaced apart from the fourth body plate.

[0124] (ii) The other of the two lids 020 is connected to the fourth body plate, that is, the lid body 021 of the lid 020 is connected to the fourth body plate, and the lid tongue 022 of the lid 020 is inserted into the interior of the cardboard box 000 on the side near the second body plate 012. At this time, the limiting block 3221 protrudes from the inner wall of the second body plate 012. It can be understood that the minimum vertical distance between the second body plate 012 and the lid tongue 022 is greater than the minimum vertical distance between the limiting block 3221 and the lid tongue 022. That is, the side of the limiting block 3221 facing the lid tongue 022 is located on the side of the second body plate 012 facing the fourth body plate, that is, the extended surface of the side of the limiting block 3221 facing the lid tongue 022 extends into the cavity of the cardboard box 000 and is spaced apart from the second body plate 012.

[0125] For example, refer to Figure 1 In one embodiment of the present invention, the paper box forming and packaging equipment further includes a finished product ejection mechanism 600, which is located on the side of the folding mechanism 300 away from the product pushing mechanism 200. The paper box 000 is conveyed to the finished product ejection mechanism 600 through the translation module 510 and the clamping module 520, and the finished product ejection mechanism 600 is used to push the packaged target product and the paper box 000 to the next process.

[0126] In this embodiment, the paper box forming and packaging equipment also includes a finished product ejection mechanism 600. After the sealed paper box 000 is conveyed to the finished product ejection position under the drive of the translation module 510 and the clamping module 520, the translation module 510 and the clamping module 520 return to their original positions, and the finished product ejection mechanism 600 pushes the finished product to the next process for processing, thereby improving the continuity of the entire packaging process.

[0127] Specifically, refer to Figure 13 The finished product ejection mechanism 600 includes a push block 610, a fifth power source 620, and a mounting block 630. The mounting block 630 is connected to the fifth power source 620, and the push block 610 is connected to the mounting block 630 and directly abuts against the cardboard box 000. The fifth power source 620 can be a telescopic cylinder or a telescopic rod, etc., and is not limited here.
