Description

Technical Field

[0001] This application belongs to the field of automatic packaging equipment, and in particular relates to a bottomless guide rail lid-opening and cartoning machine. Background Technology

[0002] Traditional cartoning machines typically use a bottom guide rail structure to support the movement of the box blank at the bottom. This bottom guide rail needs to run through the entire bottom folding station area, increasing the overall height of the equipment and requiring a multi-layered mounting frame. Furthermore, complex clearance spaces must be reserved between the bottom guide rail and the moving parts of the bottom folding mechanism. Over long-term operation, paper scraps and debris easily accumulate on the bottom guide rail, requiring frequent shutdowns for cleaning. Simultaneously, the high machining precision required for the bottom guide rail, and the accumulated tolerances in its fit with the bottom folding guide rod, can easily cause box blank jamming, increasing maintenance costs and failure rates. Therefore, it is necessary to solve these technical problems. Summary of the Invention

[0003] The purpose of this application is to provide a bottomless guide rail top-opening cartoning machine to solve the technical problem of complex structure in existing cartoning machines.

[0005] frame;

[0006] A drive chain is mounted on the frame;

[0007] The card holder is connected to the transmission chain and forms a through-cavity receiving cavity.

[0008] A box blank feeding conveyor belt is used to feed the target box blanks, and the feeding direction is towards the card holder;

[0009] A bridging plate connects the infeed blank conveyor belt and the card holder and is located directly below the receiving cavity;

[0010] The box bottom assembly includes a front ear guide plate for folding the bottom flap, and a first folding guide rod and a second folding guide rod for folding the box bottom cover. The front ear guide plate, the first folding guide rod, and the second folding guide rod extend into a first flat plate, a second flat plate, and a third flat plate, respectively, in the moving direction of the card holder. The bridging plate, the first flat plate, the second flat plate, and the third flat plate are connected in sequence and used to support the target box blank.

[0011] Optionally, the front ear guide plate and the bridging plate are spaced apart;

[0012] The width of the receiving cavity in the direction of movement of the card seat is greater than the distance between the front ear guide plate and the bridging plate.

[0013] Optionally, the first flat plate portion and the first folded bottom guide rod overlap at least once in the moving direction of the card holder.

[0014] Optionally, the second flat plate portion and the second folded bottom guide rod overlap at least once in the moving direction of the card holder.

[0015] Optionally, the bottomless guide rail lid-opening and cartoning machine also includes a main conveyor belt;

[0016] The main conveyor belt and the transmission chain are arranged in the same direction and connected to the end of the third flat plate that is away from the second flat plate.

[0017] Optionally, the main conveyor belt and the transmission chain are connected to the same drive spindle.

[0018] Optionally, the bottomless guide rail top-opening cartoning machine also includes a side guide rail connected to the frame;

[0019] The side guide rail is parallel to the transmission chain, and the card holder forms a U-shaped cross section in the vertical direction and cooperates with the side guide rail to form the receiving cavity.

[0020] Optionally, a notch is formed on the card holder for the side guide rail to pass through.

[0021] Optionally, the bottomless guide rail opening and boxing machine further includes a bottom closing rear ear rod rotatably mounted on the frame and used to strike the bottom folding ear during rotation;

[0022] The bridging plate is provided with an opening slot to avoid interference with the bottom closing lug.

[0023] Optionally, the bottomless guide rail opening and boxing machine also includes an upper ear plate and a pressure strip located above the card holder. The pressure strip is connected to the back of the upper ear plate according to the moving direction of the card holder. The upper ear plate is used to strike the opening fold ear located in front of the upper opening of the target box blank during rotation, causing it to flip forward and outward. The pressure strip is used to make the opening fold ear behind the upper opening of the target box blank flip backward and outward, and to keep the front opening fold ear and the rear opening fold ear in an outward flipped state.

[0024] The beneficial effects of the bottomless guide rail top-opening carton filling machine provided in this application are as follows: Compared with the prior art, the bottomless guide rail top-opening carton filling machine provided in this application innovatively utilizes the first flat plate extending from the bottom-closing front ear guide plate, the second flat plate extending from the first bottom-folding guide rod, the third flat plate extending from the second bottom-folding guide rod, and the bridging plate between the box blank conveyor belt and the card seat. These four components together form a continuous support surface, providing bottom support throughout the entire movement of the box blank, thereby eliminating the need for traditional bottom guide rails. This significantly simplifies the mechanical structure and effectively avoids the malfunctions that are prone to occur with traditional bottom guide rails, making it far superior to the prior art.

[0037] Please refer to the following: Figures 1 to 6 This application describes a bottomless guide rail top-opening carton filling machine. The bottomless guide rail top-opening carton filling machine includes a frame 101, a drive chain 102, a card holder 103, a preform feeding conveyor belt 105, a bridging plate 106, and a bottom-closing assembly. Wherein:

[0038] A drive chain 102 is mounted on a frame 101; a mounting bracket 103 is connected to the drive chain 102 and forms a through-hole receiving cavity 104; a box blank feeding conveyor belt 105 is used to feed the target box blank 200 and the feeding direction is towards the mounting bracket 103; a bridging plate 106 connects the box blank feeding conveyor belt 105 and the mounting bracket 103 and is located directly below the receiving cavity 104; the box bottom closing assembly includes a front closing ear guide plate 107 for folding the bottom folding ear 201, and also includes a folding... The first folding guide rod 108 and the second folding guide rod 109 of the bottom cover 202, the closing front ear guide plate 107, the first folding guide rod 108 and the second folding guide rod 109 extend into a first flat plate 110, a second flat plate 111 and a third flat plate 112 respectively in the moving direction of the card holder 103. The bridging plate 106, the first flat plate 110, the second flat plate 111 and the third flat plate 112 are connected in sequence and used to support the target box blank 200.

[0039] In this embodiment, the transmission chain 102 is used to connect a power source such as a motor and to drive the card holder 103 to rotate cyclically. The box blank conveyor belt 105 can send the folded target box blank 200 into the receiving cavity 104. Generally, the shape of the receiving cavity 104 is adapted to the shape of the target box body, so that the target box blank 200, folded into a flat shape, can automatically unfold after entering the receiving cavity 104 and abut against the bridge plate 106 through the box bottom cover 202, which is still in a vertical state. In specific implementation, a material pulling suction cup or other structure can also be set on the other side of the transmission chain 102, so as to transfer the target box blank 200 on the box blank conveyor belt 105 to the receiving cavity 104 on the card holder 103 more stably. It is understood that the material pulling suction cup or other structure can adopt the technology of existing top-opening box-packing machines.

[0040] Once the target box blank 200 unfolds in the receiving cavity 104, it can move along with the card holder 103 and sequentially pass through the bottom closing front ear guide plate 107, the first bottom folding guide rod 108, and the second bottom folding guide rod 109. These three components can be configured in shapes commonly used in the art, allowing the bottom folding ear 201 and the bottom cover 202 of the target box blank 200 to fold into place sequentially. In a preferred embodiment, the bottom closing front ear guide plate 107, the first bottom folding guide rod 108, and the second bottom folding guide rod 109 also extend into a first flat plate portion 110, a second flat plate portion 111, and a third flat plate portion 112, respectively. Since the first flat plate portion 110, the second flat plate portion 111, and the third flat plate portion 112 are sequentially connected, they can serve as a bottom support structure for the target box blank 200 to prevent it from falling out of the vertically penetrating receiving cavity 104.

[0041] According to the structure provided in this embodiment, the bottomless guide rail carton opening and packing machine provided in this embodiment innovatively utilizes the first flat plate portion 110 extending from the bottom closing front ear guide plate 107, the second flat plate portion 111 extending from the first bottom folding guide rod 108, the third flat plate portion 112 extending from the second bottom folding guide rod 109, and the bridging plate 106 between the box blank conveyor belt 105 and the card seat 103. These four components together form a continuous support surface that provides bottom support throughout the movement of the box blank, thereby eliminating the need for traditional bottom guide rails. This significantly simplifies the mechanical structure and effectively avoids the malfunctions that are prone to occur with traditional bottom guide rails, making it far superior to existing technologies.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The bottom-closing front ear guide plate 107 and the bridging plate 106 are spaced apart; the width of the receiving cavity 104 in the moving direction of the card holder 103 is greater than the distance between the bottom-closing front ear guide plate 107 and the bridging plate 106. According to the structure provided in this embodiment, since the width of the receiving cavity 104 in the moving direction of the card holder 103 is greater than the distance between the bottom-closing front ear guide plate 107 and the bridging plate 106, the target box blank 200 located in the receiving cavity 104 can simultaneously overlap the bottom-closing front ear guide plate 107 and the bridging plate 106 during the movement. This can not only form a stable bottom support for the target box blank 200, but also further simplify the structure of the bottomless guide rail box opening and packing machine in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The first flat plate portion 110 and the first folding bottom guide rod 108 overlap at least once in the moving direction of the card holder 103. According to the structure provided in this embodiment, the overlapping first flat plate portion 110 and the first folding bottom guide rod 108 can make the target box blank 200 transition smoothly between the two, so that the bottomless guide rail box opening and packing machine in this embodiment can provide more stable support for the target box blank 200.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The second flat plate portion 111 and the second folding bottom guide rod 109 overlap at least once in the moving direction of the card holder 103. According to the structure provided in this embodiment, the overlapping second flat plate portion 111 and the second folding bottom guide rod 109 allow the target box blank 200 to smoothly transition between the two while simultaneously folding the bottom cover 202 on the other side. Thus, the bottomless guide rail box opening and packing machine in this embodiment can provide more stable support for the target box blank 200.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The bottomless guide rail box-opening and packing machine also includes a main conveyor belt 113; the main conveyor belt 113 and the transmission chain 102 are arranged in the same direction and connected to the end of the third flat plate 112 away from the second flat plate 111. According to the structure provided in this embodiment, after the target box blank 200 passes through the bottom closing front ear guide plate 107, the first bottom folding guide rod 108 and the second bottom folding guide rod 109 in sequence, its bottom folding ear 201 and box bottom cover 202 are closed. At this time, the bottom of the target box blank 200 is closed and can be used to load materials. Transferring it to the main conveyor belt 113 can facilitate the filling of materials and also provide more stable support through the main conveyor belt 113.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The main conveyor belt 113 and the drive chain 102 are connected to the same drive shaft. According to the structure provided in this embodiment, the main conveyor belt 113 and the drive chain 102 connected to the same drive shaft can run stably and synchronously. This makes it less likely for the box blank 200 to be damaged during the process of transferring from the third flat plate 112 to the main conveyor belt 113. This also makes the box blank 200 more stably supported by the bottomless guide rail box-opening and box-packing machine in this embodiment.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The bottomless guide rail top-opening cartoning machine also includes a side guide rail 114 connected to the frame 101. The side guide rail 114 is parallel to the transmission chain 102, and the card holder 103 forms a U-shaped cross section in the vertical direction and cooperates with the side guide rail 114 to form a receiving cavity 104. According to the above structure provided in this embodiment, the side guide rail 114, which is parallel to the transmission chain 102, can provide stable guidance for the target box blank 200 during its movement, and can also limit the target box blank 200 inserted into the receiving cavity 104. In this way, the target box blank 200 will not fall out of the receiving cavity 104 during the process of the bottom folding ear 201 and the bottom cover 202 being folded. This can further enable the bottomless guide rail top-opening cartoning machine in this embodiment to provide stable support for the target box blank 200.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 A notch 115 is formed on the card holder 103 for the side guide rail 114 to pass through. According to the structure provided in this embodiment, the notch 115 formed on the card holder 103 allows the side guide rail 114 to more fully abut against the target box blank 200, thereby helping to further improve the movement stability of the target box blank 200.

[0049] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The bottomless guide rail carton opening and packing machine also includes a bottom-closing rear lug 116 rotatably mounted on the frame 101 and used to strike the bottom flap 201 during rotation; the bridging plate 106 is provided with an opening slot 117 to avoid interference with the bottom-closing rear lug 116. According to the structure provided in this embodiment, the opening slot 117 formed on the bridging plate 106 can not only avoid interference with the bottom-closing rear lug 116, but also enable the bridging plate 106 to provide stable support for the target box blank 200 during the process of the bottom-closing rear lug 116 striking the bottom flap 201 on the rear side of the target box blank 200. This further enables the bottomless guide rail carton opening and packing machine in this embodiment to provide stable support for the target box blank 200. It should be noted that the bottom-closing rear ear rod 116 can strike the bottom folding ear 201 located on the rear side of the target box blank 200 during the rotation in a preset direction, so that the bottom folding ear 201 on the rear side is folded inward to a set position in advance before reaching the bottom-closing front ear guide plate 107, so that the bottom folding ear 201 can be folded more stably by the bottom-closing front ear guide plate 107. This matching structure is a conventional technical means in the field and will not be described in detail here.

[0050] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The bottomless guide rail box-opening and packing machine also includes an upper ear plate 118 and a pressure strip 119 located above the card holder 103. The pressure strip 119 is connected to the back of the upper ear plate 118 in the direction of movement of the card holder 103. The pressure strip 119 extends a set length in the direction of movement of the card holder 103. The upper ear plate 118 is used to strike the opening fold ear 203 located in front of the upper opening of the target box blank 200 during rotation, causing it to flip forward and outward. The pressure strip 119 is used to make the opening fold ear 203 behind the upper opening of the target box blank 200 flip backward and outward, and to keep the front opening fold ear 203 and the rear opening fold ear 203 in an outward flipped state. As the preferred embodiment, the upper ear plate 118 is located above the bottom closing front ear guide plate 107, so that the target box blank 200 can be reliably supported. It is understandable that the upper ear plate 118 and the lower ear rod 116 are both mounted on a rotating shaft. The rotating shaft is rotatably mounted on the frame 101. The rotating shaft is perpendicular to the direction of movement of the transmission chain 102 and is driven by a separate servo motor or connected to the transmission chain of the whole machine to reciprocate around its own axis at a set angle.

[0051] According to the structure provided in this embodiment, the flap 203 can be in an outward-facing state to facilitate the loading station of the cartoning machine in this embodiment to load materials into the box that has been formed from the target box blank 200. It is understood that the cartoning machine in this embodiment may also include the loading station and the box closing assembly, which pushes the packaged box out of the card holder 103 and laterally separates it from the main conveyor belt 113 and enters the finished product conveyor belt. These supporting structures can adopt the technology of existing cartoning machines.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
