Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a carton forming machine. Background Art

[0002] As people's living standards continue to improve, energy conservation and environmental protection awareness has been deeply rooted in people's minds. Many companies use cartons for their products. In the field of packaging televisions, cartons are usually used. Cartons need to be folded in advance so that they can be used by the next workstation. When not in use, cartons are flat for easy storage. Therefore, before packaging products in cartons, a bottom sealing process is required to fold the carton into a cavity with a storage space.

[0003] In order to allow users to choose different types of cartons according to actual needs, the folding shapes of cartons are usually different, so the sealing methods of cartons will also be different. For example, for flat-mouth cartons, a glue structure is generally used to fold multiple folding edges and then glue them together; for tongue-type cartons, multiple folding edges are plugged and fixed through a plug-in mechanism; the packaging processes of these two types of carton products are different. In order to produce these two different cartons, manufacturers often need to set up two independent production lines, which consumes more financial and human resources. Utility Model Content

[0048] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0053] In order to allow users to choose different types of cartons according to actual needs, the folding shapes of cartons are usually different, so the sealing methods of cartons will also be different. For example, for flat-mouth cartons, a glue structure is generally used to fold multiple folding edges and then glue them together; for tongue-type cartons, multiple folding edges are plugged and fixed through a plug-in mechanism; the packaging processes of these two types of carton products are different. In order to produce these two different cartons, manufacturers often need to set up two independent production lines, which consumes more financial and human resources.

[0054] Based on this, the utility model proposes a carton forming machine. In order to make the carton forming machine adaptable to the production of multiple types of carton products, the carton forming machine is detachably provided with a forming mechanism, so that the carton forming machine can replace different forming mechanisms according to the shape of the carton folding edge, is compatible with the production of multiple types of carton products, and has a wider range of applications.

[0055] like Figure 1 - Figure 7 As shown, the carton forming machine is used to bulge a flat carton to form a receiving space with an opening, and a plurality of folding edges are provided around the opening. The carton forming machine includes:

[0056] A rack 100, for placing cartons;

[0057] The suction mechanism 200 is disposed on the frame 100 and is used to suction the carton so that it is bent according to a preset fold to form a receiving space;

[0058] A folding mechanism 300 is provided on the frame 100 and located at one side of the adsorption mechanism 200, and the folding mechanism 300 is used for folding the folded edge to close the opening; and

[0059] The forming mechanism 400 is detachably mounted on the frame 100 to fix the multiple folded edges folded by the folding mechanism 300 .

[0060] In the technical solution adopted in this embodiment, when forming a carton, first place a flat carton on the frame 100, and bend the carton according to the preset folds through the adsorption mechanism 200 to form a containing space with an opening; in order to close the opening on the carton, the carton forming machine is also provided with a folding mechanism 300, through which multiple folds around the opening can be folded to close the opening; in order to fix multiple folds to ensure the complete packaging of the opening, a forming mechanism 400 can also be detachably provided on the frame 100, so that multiple folds are installed with preset folds after being folded by the folding mechanism 300, and then fixed by the forming mechanism 400 to complete the forming and packaging of the carton, replacing the traditional manual work and effectively improving the forming efficiency of the carton. In addition, the forming mechanism 400 in this solution is detachably connected to the frame 100, so that the carton forming machine can replace different forming mechanisms 400 according to the shape of the carton fold, compatible with the production of various types of carton products, and more widely applicable.

[0061] Specifically, the carton is generally flat before being formed, and there are two openings on the carton. The carton forming machine needs to seal the first opening on the carton first, and then seal the second opening after the accommodating space of the carton is filled with articles. It should be noted that when the carton forming machine seals the first opening, it needs to first bulge the carton through the adsorption mechanism 200, and then fold multiple folds through the folding mechanism 300, and then form it through the forming mechanism 400 for standby use; after filling the articles, the carton can also be placed on the frame 100 for packaging, and the folding mechanism 300 folds the fold at the second opening, and then the forming mechanism 400 forms it, and the packaging of the articles can be completed. The use of the carton forming machine can simplify the forming process of the carton and effectively improve the product packaging efficiency.

[0062] Alternatively, if Figure 2 - Figure 4 As shown, in one embodiment of the utility model, for a carton with a flat-edge fold, multiple folds need to be bonded and fixed, and the forming mechanism 400 includes a gluing component 410, and the gluing component 410 is arranged on one side of the folding mechanism 300. Preferably, the gluing component 410 can be snap-fitted to the frame 100 for easy replacement. It can be understood that the folding usually includes two upper and lower folds and two left and right folds. When the folding mechanism 300 performs the folding process, the left and right folds can be folded first, and then the upper and lower folds can be folded again, and finally the upper and lower folds can be bonded and fixed by the gluing component 410.

[0063] Alternatively, if Figure 4 As shown, in one embodiment of the present utility model, the adhesive assembly 410 includes:

[0064] The mounting plate 411 is detachably connected to the frame 100;

[0065] A glue pressing wheel 413 is rotatably mounted on the mounting plate 411, and the glue pressing wheel 413 is used to adhere the adhesive tape to the carton and press the adhesive tape and the carton tightly; and

[0066] The glue supply device 415 is rotatably disposed on the mounting plate 411 , and a tape is wound around the outer circumference of the glue supply device 415 for conveying the tape to the glue pressing wheel 413 .

[0067] Specifically, by detachably connecting the mounting plate 411 to the frame 100, the entire glue assembly 410 can be detachable, and there is no specific limitation on the specific detachable method, for example, it can be a snap-on connection, or it can be a screw connection, etc.; in addition, the glue assembly 410 also includes a glue pressing wheel 413 and a glue supplier 415 that can rotate on the mounting plate 411. Preferably, a plurality of traction rods can be provided between the glue pressing wheel 413 and the glue supplier 415 to ensure the unfolding direction of the tape; it should be noted that the outer periphery of the glue supplier 415 is wrapped with tape, and the tape is smoothly extended to the glue pressing wheel 413 through the guidance of a plurality of traction rods arranged at intervals, so that the non-stick surface of the tape abuts against the outer surface of the glue pressing wheel 413.

[0068] The specific gluing process is as follows: the initial state of the glue pressing wheel 413 is that it protrudes from the mounting plate 411 and is close to the side of the carton. The carton is placed horizontally on the conveying mechanism on the frame 100. The conveying mechanism transports the carton with completed folding to the forming mechanism 400. When the carton just arrives at the forming station, the part of the glue pressing wheel 413 protruding from the mounting plate 411 will first abut against the left side of the carton, and the head of the tape will be glued to the left side. Then the conveying mechanism continues to convey the carton along the frame 100. The glue pressing wheel 413 is slowly rotated to a position flush with the side of the mounting plate 411 under the push of the carton, and abuts against the tape, and the tape and the carton are pressed tightly to ensure the bonding strength; preferably, an auxiliary wheel can also be provided on the side of the glue pressing wheel 413 away from the folding mechanism 300. The initial state of the auxiliary wheel is a position flush with the side of the mounting plate 411. After the glue pressing wheel 413 completes the first round of gluing, the auxiliary wheel will immediately perform a second round of gluing to further improve the gluing effect. Preferably, a rubber cutting knife can be provided between the rubber pressing wheel 413 and the auxiliary wheel. When all the folded edges are glued, a certain length of tape needs to be reserved before cutting it. At this time, the auxiliary wheel will rotate to a position protruding from the side of the mounting plate 411, abut against the right side of the carton, and stick the reserved tape part to the right side. It should be pointed out that the speed of the rubber pressing wheel 413 should be slow when it first contacts the carton, and it should also be slow when it is about to leave the carton, to prevent the carton from being damaged by too fast speed or the tape from being unevenly adhered.

[0069] Alternatively, if Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment of the utility model, for a carton with a tongue-shaped fold, multiple folds need to be plugged and fixed, and the forming mechanism 400 includes a propulsion assembly 420, which is arranged on one side of the folding mechanism 300. Preferably, the propulsion assembly 420 can be connected to the frame 100 by a buckle for easy replacement, and is used to drive the plugging of two relatively arranged folds. In this way, the carton forming machine can complete the forming process of various types of cartons by only changing the type of the forming mechanism 400.

[0070] Alternatively, if Figure 5 As shown, in one embodiment of the present invention, the propulsion assembly 420 includes:

[0071] A fixing frame 421, detachably connected to the frame 100;

[0072] A guide block 423 is slidably disposed on the fixing frame 421, and the guide block 423 abuts against the folded edge; and

[0073] The propulsion cylinder 425 has a fixed end disposed on the fixed frame 421 , and a telescopic end of the propulsion cylinder 425 is drivingly connected to the guide block 423 to drive the guide block 423 to slide.

[0074] Specifically, by detachably connecting the fixed frame 421 to the frame 100, the entire propulsion assembly 420 can be detachable. The specific detachable method is not specifically limited, for example, it can be a snap connection or a screw connection. In order to plug multiple hems, it is necessary to abut the guide block 423 against the plug tongue on the hem, and push the guide block 423 toward the inside of the carton under the power of the propulsion cylinder 425 until the plug tongue on one of the hems is inserted into the inside of another opposite hem for fixing. It should be noted that the guide block 423 is slidably set on the fixed frame 421, and the fixed position of the guide block 423 can be adjusted according to the width and position of the plug tongue of different cartons.

[0075] Alternatively, if Figure 3 As shown, in one embodiment of the utility model, the plurality of folding edges include two relatively long folding edges and two relatively short folding edges, and the folding mechanism 300 includes:

[0076] A long folding edge assembly 310, provided on the frame 100, for folding the long folding edge; and

[0077] The short folding edge assembly 320 is disposed on the frame 100 and is used for folding the short folding edges.

[0078] Specifically, in order to facilitate folding multiple hems, the carton forming machine is also provided with a long hem assembly 310 and a short hem assembly 320. For example, the folding of the hems can be completed by setting up multiple cylinders. It should be noted that the number of long hem assemblies 310 can be equal to the number of long hems and be set accordingly. Each long hem assembly 310 is used to fold a long hem alone, or one long hem assembly 310 can be used to complete the folding of two long hems at the same time; similarly, the short hem assemblies 320 are also the same. There can be one or a number equal to the number of short hems.

[0079] Alternatively, if Figure 3 As shown, in one embodiment of the present utility model, the adsorption mechanism 200 includes:

[0080] A swing arm assembly 210 movably disposed on the frame 100; and

[0081] The adsorption plate 220 is fixedly connected to the swing arm assembly 210 and is used to adsorb the carton. The swing arm assembly 210 drives the adsorption plate 220 to rotate so that the carton is bent according to a preset crease.

[0082] Specifically, a plurality of suction cups are provided on the side of the adsorption plate 220 facing the carton, and the flat carton is firmly adsorbed on the suction cups and fixed on the adsorption plate 220. The adsorption plate 220 is driven to swing by the movement of the swing arm assembly 210 on the frame 100, and the carton swings at a certain angle driven by the adsorption plate 220 until the carton is unfolded according to the preset fold. It should be noted that the swing arm assembly 210 can also be connected to a cylinder, and the cylinder is used to provide the swing arm assembly 210 with power for swinging.

[0083] Optionally, in an embodiment of the utility model, considering that the thickness of the folded edges of cartons of different sizes is different, the height of the forming mechanism 400 also needs to be adjusted accordingly, and the carton forming machine further includes a lifting mechanism installed on the frame 100, and the forming mechanism 400 is detachably arranged on the lifting mechanism, and the forming mechanism 400 can be raised and lowered under the drive of the lifting mechanism. There is no specific limitation on the type of the lifting mechanism, for example, it can be driven by a motor screw rod or a cylinder.

[0084] Alternatively, if Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in one embodiment of the utility model, in order to store the cartons to be formed, the carton forming machine further includes a storage bin 500, which is arranged on the side of the adsorption mechanism 200 away from the forming mechanism 400. The storage bin 500 has an upper bin 510 and a lower bin 520 that are connected. The upper bin 510 is used to store a large number of flat cartons and sequentially transfer the cartons to the lower bin 520. It should be noted that the number of cartons transferred from the upper bin 510 to the lower bin 520 each time is not specifically limited, for example, it can be one or two or more, and no more than ten at most. In this way, the conveying mechanism 600 can take out the cartons from the lower bin 520, rather than taking out the cartons from the more cartons in the upper bin 510 for conveying, which can disperse the gravity of the conveying mechanism 600 taking out the cartons from the storage bin 500, which is conducive to improving the material taking efficiency. It should be noted that the number of cartons transferred from the upper warehouse 510 to the lower warehouse 520 each time can be limited by the warehouse height of the lower warehouse 520.

[0085] Alternatively, if Figure 6 As shown, in one embodiment of the present utility model, the storage tank 500 includes:

[0086] A pressing assembly 530 is disposed in the upper bin 510 and is used to press the cartons in the upper bin 510; and

[0087] The pallet assembly 540 is disposed in the lower bin 520 and is used to receive cartons dropped from the upper bin 510 into the lower bin 520 .

[0088] Specifically, in order to improve the fixing strength of the carton, an extrusion assembly 530 is further provided on the opposite sides of the upper warehouse 510, such as an extrusion cylinder. Preferably, a plurality of extrusion cylinders are provided at intervals, and the carton can be stably fixed in the upper warehouse 510 by the extrusion cylinder; further, the two opposite sides of the extrusion cylinder can also be embossed to improve the friction with the carton; further, the extrusion cylinder on each side can be slidably set on the guide rail so as to adjust the position of the extrusion cylinder according to the size of the carton and the position of the tongue on the carton. It can be understood that a pallet assembly 540 can also be provided in the lower warehouse 520, such as a pallet cylinder; when it is necessary to transfer the carton to the lower warehouse 520, the extrusion cylinder can be retracted, and the carton falls onto the pallet assembly 540. After the unloading is completed, the extrusion cylinder extends to clamp the carton. It should be noted that, in order to separate the upper and lower bins 520, a partition is further provided in the bin 500. Preferably, the partition is connected to a cylinder, and the partition can be extended into the bin 500 under the drive of the cylinder to support the cartons in the upper bin 510; or, it can be retracted in a direction away from the bin 500 to unload the upper bin 510 to the lower bin 520. It can be understood that the extension position of the partition determines the number of cartons that can be stored in the lower bin 520.

[0089] Alternatively, if Figure 6 As shown, in one embodiment of the utility model, in order to improve the fixing strength of the storage bin 500 to the cartons, the storage bin 500 also includes a clamping assembly 550. Preferably, the clamping assembly 550 extends from the upper bin 510 to the lower bin 520, and is used to clamp the cartons in the storage bin 500. In this way, it can be ensured that when the conveying mechanism 600 takes materials from the bottom of the lower bin 520, only the bottom carton is taken out each time, and the other cartons are clamped and fixed by the clamping assembly 550, and will not slide relative to the bottom carton.

[0090] Alternatively, if Figure 6 and Figure 7 As shown, in one embodiment of the utility model, the clamping assembly 550 includes a first clamping plate 551 and a second clamping plate 553 which are spaced apart. The first clamping plate 551 and the second clamping plate 553 are both slidably arranged in the storage bin 500, and the carton is clamped between the first clamping plate 551 and the second clamping plate 553. A screw rod and a stepper motor transmission mechanism are also provided in the storage bin 500. The stepper motor drives the screw rod to rotate, and the positions of the first clamping plate 551 and the second clamping plate 553 in the storage bin 500 are adjusted respectively, so that they are suitable for cartons of various sizes.

[0091] Alternatively, if Figure 6 As shown, in one embodiment of the utility model, in order to transport the cartons in the lower bin 520 to the folding mechanism 300 and the adsorption mechanism 200, the carton forming machine also includes a conveying mechanism 600, which is slidably arranged on the frame 100. Preferably, the conveying mechanism 600 reciprocates between the folding mechanism 300 and the lower bin 520. The conveying mechanism 600 can be a rubber suction cup, and a lifting cylinder is provided at the bottom of the rubber suction cup, so that the rubber suction cup rises when taking and feeding materials, and falls when moving between the two mechanisms; further, for the reciprocating motion of the rubber suction cup, a stepping motor can be provided on the frame 100 to drive it, so as to ensure the accuracy of each positioning.

[0092] Alternatively, if Figure 1 As shown, in one embodiment of the utility model, in order to place the finished carton products neatly, the carton forming machine further includes a finished product output mechanism 700. Preferably, the finished product output mechanism 700 is arranged on the side of the forming mechanism 400 away from the adsorption mechanism 200. The carton packaged and formed by the forming mechanism 400 can be output to the finished product output mechanism 700 one by one through a conveying mechanism. After the finished product output mechanism 700 adjusts the position of each carton, multiple packaged and formed carton boxes can be placed more neatly for later use. Preferably, the finished product output mechanism 700 can be a roller conveyor line composed of multiple rollers.

[0093] Alternatively, if Figure 1As shown, in one embodiment of the utility model, since the opening of the carton is placed horizontally on the frame 100 when it is packaged, in order to facilitate the later loading of articles into the carton, the carton forming machine also includes a flipping mechanism 800. Preferably, the flipping mechanism 800 is arranged between the forming mechanism 400 and the finished product output mechanism 700. In this way, the carton packaged and formed by the forming mechanism 400 can be output to the flipping mechanism 800. The carton can be flipped at a preset angle under the drive of the flipping mechanism 800, and then output to the finished product output mechanism 700 for standby. It should be noted that there is no specific limitation on the specific flipping angle of the carton, for example, it can be 90 degrees, or any other angle, which needs to be determined according to the placement angle of the carton when it is formed, as long as the carton can be rotated to an angle that is convenient for filling articles into the accommodating space.
