Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a box feeding mechanism capable of adaptively adapting to material specifications. Background Art

[0002] The automatic cartoning equipment is equipped with equipment components such as conveyor belts and carton folding mechanisms. During the process of conveying materials, the cartons are folded into shape and the materials are automatically loaded into them. When replacing cartons of different specifications, the existing cartoning equipment needs to manually adjust the length, width, and height of the track used to convey the cartons, and the height and width of the push head mechanism that pushes the materials into the box need to be adjusted accordingly. It is also necessary to make corresponding adjustments to the action mechanisms used to fold the cartons, such as the large tongue closing mechanism and the small tongue closing mechanism, according to the adjustment of the conveying mechanism. Such adjustment methods and the replacement and adjustment of the conveying and action mechanisms will consume more working time, and also put forward higher requirements on the skills of the debugging cartoning personnel. Therefore, its work efficiency is not only subject to the adjustment cycle, but also affected by the technical ability of the operators. Summary of the invention

[0003] The purpose of the present invention is to provide a box feeding mechanism that is adaptive to material specifications to solve the above technical problems.

[0006] The material pushing and box feeding assembly is arranged at the rear side of the upper and lower synchronous box feeding assembly and is located on the right side of the tongue closing assembly, so as to facilitate pushing the packaged material into the open box body before the tongue of the box body is closed;

[0007] The unfolded and formed paper box prototypes are arranged in a pile in the paper box placement groove, and the paper box prototypes are in the shape of sheets. The paper box placement groove has an inclined unloading rack, and any paper box prototype is placed vertically on the unloading rack. The bottom of the lowest end of the unloading rack is provided with a stop bar, and the paper box prototype is blocked by the stop bar in the process of being pulled out of the unloading rack by the suction box assembly, so that it is stretched into an open box body; in the process of the suction box assembly moving the open box body with the unclosed tongue to the pushing box assembly, the open box body is flipped to a position where it is convenient to close the tongue when it is transferred in the upper and lower synchronous box feeding assemblies; after the pushing box assembly sucks the open box body structure with the unclosed tongue from the suction box assembly, it is pushed to the rightmost side of the upper and lower synchronous box feeding assembly, and is pushed from right to left into the conveying station of the upper and lower synchronous box feeding assembly in operation; in the process of conveying from right to left, the pushing box assembly pushes the packaged material into the open box body, and then during the conveying process, the tongue plate of the box body is closed by the closing tongue assembly to close the box body;

[0008] The upper and lower synchronous box feeding components include an upper synchronous belt component, a lower synchronous belt component, a length adjustment component and a height adjustment component. The upper synchronous belt component includes an upper synchronous belt front baffle and an upper synchronous belt rear baffle arranged at a front and rear interval, and an upper synchronous belt is provided in each of the two components. The lower synchronous belt component includes a lower synchronous belt front baffle and a lower synchronous belt rear baffle arranged at a front and rear interval, and a lower synchronous belt is provided in each of the two components.

[0009] The length adjustment component is connected to the upper synchronous belt front baffle and the lower synchronous belt front baffle, and the length adjustment component adjusts the distance between the upper synchronous belt front baffle and the upper synchronous belt rear baffle, and simultaneously adjusts the distance between the lower synchronous belt front baffle and the lower synchronous belt rear baffle;

[0010] The height adjustment assembly is connected to the upper synchronous belt front baffle and the upper synchronous belt rear baffle, so that the upper and lower intervals between the upper synchronous belt assembly and the lower synchronous belt assembly are increased or decreased after the entire assembly is raised or lowered.

[0011] The present invention realizes the function of the paper supply box part by setting a sucking box assembly, a pushing box assembly, an upper and lower synchronous box feeding assembly, and a material pushing box assembly. The upper and lower synchronous box feeding assembly with a length and height adjustment assembly realizes the automatic adjustment of the upper synchronous belt assembly and the lower synchronous belt assembly corresponding to the paper boxes of different specifications and sizes, and makes the mechanism body correspond to the box feeding requirements of paper boxes of different specifications and sizes according to actual needs. Among them, when the length adjustment assembly is working, the spacing distance (front and back direction) between the two baffles of the upper synchronous belt assembly is increased or decreased, and at the same time, the spacing distance (front and back direction) between the two baffles of the lower synchronous belt assembly is also synchronously increased or decreased by the same distance, so as to correspond to paper boxes of different lengths; when the height adjustment assembly is working, the upper synchronous belt assembly is lifted or lowered as a whole relative to the lower synchronous belt assembly, so as to increase or decrease the spacing distance (up and down direction) between the upper synchronous belt assembly and the lower synchronous belt assembly, so as to correspond to paper boxes of different heights; when the upper synchronous belt assembly and the lower synchronous belt assembly are misaligned, the width of the placement station on the conveying surface can be adjusted, so as to correspond to paper boxes of different widths.

[0012] It should be noted that the power of each component of the present application can be provided by a servo motor, including the box suction component, the box pushing component, the upper and lower synchronous box feeding component, and the material pushing into the box component can all use the servo motor as the power supply source to improve the movement accuracy, especially in the upper and lower synchronous box feeding component, when the corresponding servo motor drives different action components to complete the corresponding adjustment of the length, width and height dimensions of the mechanism body to the paper boxes of different sizes, it has better real-time performance and movement accuracy.

[0013] In addition, the mechanism body of the present application can be edited and produced by the upper system that controls the servo motor to form adjustment instructions for corresponding adjustments to paper boxes of different specifications and sizes. After the adjustment instructions are connected with the corresponding external control buttons, when the mechanism body needs to be adjusted to be suitable for the transportation of a certain type of paper box, it is only necessary to trigger the corresponding control button to achieve the one-key switching effect. Compared with the backward method in the traditional production structure that requires manual adjustment of related components of the conveying equipment, the present application is not only highly efficient, so that the adjustment action can be completed quickly in an automated manner, but also saves labor and time costs, and is not dependent on the technical level of the operator. It is particularly suitable for production occasions with a certain degree of automation.

[0054] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A box feeding mechanism with adaptive material specifications includes a mechanism body, the mechanism body includes a paper feeding box part and a material feeding part, the material feeding part is located on one side of the paper feeding box part, and the two are respectively equipped with a frame and a bottom plate, the bottom plate is a flat plate structure with mounting grooves and mounting holes, and the frame is a frame structure built by columns and beams, such as Figure 1 As shown, the paper supply box portion is arranged on the bottom plate 101 , and both the paper supply box portion and the bottom plate 101 are located in the frame structure of the frame 102 ; the material feeding portion is arranged on the bottom plate 201 , and both the material feeding portion and the bottom plate 201 are located in the frame structure of the frame 202 .

[0055] In the present invention, the paper supply box section is used to fold the paper box into shape and then supply it to the subsequent packaging section. The paper box placement slot 103 provides the paper box prototype 901, which is stretched and formed into an open box body by the paper supply box section, and then the packaging material 902 to be loaded into the box is sent by the feeding section through the conveying mechanism connecting the feeding section and the paper supply box section. After being packed into the box, it is packaged by the conveying and folding mechanism of the paper supply box section and then sent to the subsequent packaging link. The feeding section is used to provide the packaging material 902, and the packaging material 902 is stacked in the storage slot 203 of the feeding section. After being transported by the conveying mechanism connecting the feeding section and the paper supply box section, the packaging material 902 enters the paper supply box section and is loaded into the paper box folded into the open box body during the transportation process of the paper box.

[0056] The paper feeding box part includes a sucking box assembly 104, a pushing box assembly 105, an up-and-down synchronous box feeding assembly 106, and a material pushing into box assembly 107. A paper box placement slot 103 is provided on the right side of the sucking box assembly 104, the pushing box assembly 105 is arranged on the left side of the sucking box assembly 104, and the up-and-down synchronous box feeding assembly 106 is arranged on the left side of the pushing box assembly 105. The front and rear sides of the up-and-down synchronous box feeding assembly 106 are both provided with tongue assemblies for closing the tongue plate of the paper box to form a closed box body; the material pushing into box assembly 107 is arranged on the rear side of the up-and-down synchronous box feeding assembly 106, and is located on the right side of the tongue closing assembly, so as to facilitate pushing the package 902 into the open box body before the box body is not closed.

[0057] like Fig. 9 As shown, the paper box placement slot is filled with piles of unfolded paper box prototypes 901, which are in sheet form. The paper box prototypes 901 are in sheet form, and the paper box placement slot has an inclined unloading rack, which is composed of two groups of rack rods 1031 that are symmetrical and spaced apart from each other. Each group of rack rods includes two upper and lower rack rods, and each rack rod is an angle steel structure. The rack rods of the two angle steel structures in each group are symmetrically arranged up and down, so that the two sides of the sheet-like structure of the paper box prototype are clamped between the upper and lower rack rods. Each group of rack rods is set on an adjustment rod 1032, so that the upper or lower rack rod can be adjusted up and down along the adjustment rod, thereby adjusting the upper and lower spacing distance of the upper and lower angle steels in each group, so as to correspond to paper box prototypes of different specifications;

[0058] Any carton prototype 901 is placed vertically on the unloading rack and clamped by two sets of rack rods from the front and back directions. A stop bar 1033 is provided at the lower end of the unloading rack. When the box suction assembly sucks the single carton prototype 901 located at the lower end of the unloading rack from the carton placement slot, it is blocked by the stop bar 1033 during the suction process, and the carton prototype is stretched to an open box body 901-1 ( Fig. 9 The middle open box body has been transferred to the suction cup of the box pushing assembly); in the process of the box sucking assembly transferring the open box body 901-1 to the box pushing assembly 105, the open box body 901-1 is turned over to a position where it is convenient for closing the tongue when it is transferred in the upper and lower synchronous box feeding assembly; after the box pushing assembly 105 sucks the open box body 901-1 from the box sucking assembly, it is pushed to the rightmost side of the upper and lower synchronous box feeding assembly, and is pushed from right to left into the conveying station of the upper and lower synchronous box feeding assembly in operation; in the process of conveying from right to left, the material pushing assembly pushes the packaged material from the rear opening of the open box body 901-1 into the box body cavity, and then in the process of conveying, the front and rear tongue plates of the box body are closed by the tongue closing assembly to seal the box body;

[0059] The upper and lower synchronous box feeding components include an upper synchronous belt component, a lower synchronous belt component, a length adjustment component and a height adjustment component. The upper synchronous belt component includes an upper synchronous belt front baffle plate and an upper synchronous belt rear baffle plate arranged at a front and rear interval, and an upper synchronous belt is provided in each of the two components. The lower synchronous belt component includes a lower synchronous belt front baffle plate and a lower synchronous belt rear baffle plate arranged at a front and rear interval, and a lower synchronous belt is provided in each of the two components.

[0060] The length adjustment component is connected to the upper synchronous belt front baffle and the lower synchronous belt front baffle, and the length adjustment component adjusts the distance between the upper synchronous belt front baffle and the upper synchronous belt rear baffle, and at the same time adjusts the distance between the lower synchronous belt front baffle and the lower synchronous belt rear baffle;

[0061] The height adjustment component is connected to the upper synchronous belt front baffle and the upper synchronous belt rear baffle, so that the upper and lower intervals between the upper synchronous belt component and the lower synchronous belt component are increased or decreased after the height adjustment component is raised or lowered as a whole.

[0062] It should be noted that the paper box in the present invention is transported in the conveying station on the upper and lower synchronous box feeding components, wherein the conveying station refers to the conveying station formed between the lower conveying surface of the upper synchronous belt component and the upper conveying surface of the lower synchronous belt component. Figure 7 , Figure 8 As shown, the spacing distance between the lower conveying surface of the upper synchronous belt assembly 1061 and the upper conveying surface of the lower synchronous belt assembly 1062 is the height of the conveying station, which corresponds to the height of the paper box 901-2 being conveyed, and the upper surface of the paper box 901-2 is close to the lower conveying surface of the upper synchronous belt assembly 1061, and the lower surface is placed on the upper conveying surface of the lower synchronous belt assembly 1062; the spacing distance between the front and rear spaced synchronous belts in any synchronous belt assembly (upper synchronous belt assembly or lower synchronous belt assembly) (for example, the synchronous belt on the upper synchronous belt front baffle and the synchronous belt on the upper synchronous belt rear baffle in the upper synchronous belt assembly) is the height of the conveying station, which corresponds to the height of the paper box 901-2 being conveyed, and the upper surface of the paper box 901-2 is close to the lower conveying surface of the upper synchronous belt assembly 1061, and the lower surface is placed on the upper conveying surface of the lower synchronous belt assembly 1062; The length of the conveying station corresponds to the length of the carton, but is not equal to the length of the carton. The length of the conveying station is generally set to be less than the length of the carton, so that the carton placed in the conveying station is lifted up by the conveying surface and does not fall; any synchronous belt is provided with spaced-apart columns, and the projection of any isolation column 10631 on the synchronous belt of the upper synchronous belt assembly 1061 on the corresponding synchronous belt of the lower synchronous belt assembly 1062 and the spacing between the isolation column 10632 on the synchronous belt of the lower synchronous belt assembly 1062 located on one side (left or right) thereof is the width of the conveying station, which corresponds to the width of the carton. Figure 7 In the structure, since the projection of the isolation column of the upper synchronous belt assembly 1061 just falls on the isolation column of the lower synchronous belt assembly 1062, the width of the conveying station under this structure is equal to the spacing distance between any two adjacent isolation columns in the upper synchronous belt assembly 1061 or the lower synchronous belt assembly 1062. Figure 8As shown, according to the running direction, the width of the conveying station is defined as: the distance between the projection of the isolation column 10631 of the upper synchronous belt assembly 1061 on the upper conveying surface of the lower synchronous belt assembly and the isolation column 10632 of the lower synchronous belt assembly 1062 located on its left side. The width of the conveying station can be adjusted as follows: Figure 7 As shown, the normal operation conveying mode of the upper synchronous belt assembly 1061 and the lower synchronous belt assembly 1062 is set to synchronous operation; when the conveying station width needs to be adjusted to adapt to the paper box of the corresponding width, when the upper synchronous belt assembly 1061 and the lower synchronous belt assembly 1062 are both stationary, the synchronous belt in any of the synchronous belt assemblies is operated to run a certain distance clockwise or counterclockwise, so that the isolation fence on the synchronous belt is offset by a certain distance relative to the isolation fence on the other synchronous belt, thereby forming a new conveying station width. For example, Figure 8 As shown, when the upper synchronous belt assembly 1061 and the lower synchronous belt assembly 1062 are both stationary, the lower synchronous belt assembly 1062 is rotated clockwise to move its conveying surface a certain distance, so that a distance is separated between the projections of the isolation column 10632 thereon and the isolation column 10631 on the upper synchronous belt assembly 1061 on the conveying surface of the lower synchronous belt assembly, and this distance is the width of the conveying station, in which a paper box 901-2 with this width is placed.

[0063] It should be noted that the upper and lower spacing distance between the upper synchronous belt assembly 1061 and the lower synchronous belt assembly 1062 in the above embodiment refers to the spacing distance between the lower conveying surface of the upper synchronous belt assembly 1061 and the upper conveying surface of the lower synchronous belt assembly 1062.

[0064] In addition, the packaging in the present invention includes not only the packaging contents, but also the instructions, certificates and other accessories related to the contents, and other accessories such as carton liners, etc. The feeding part shown in the drawings of the present invention takes the carton liners as the conveyed packaging as an example.

[0065] When the packages in the applicable occasions of the present invention are not easy to be sucked up by the suction cup, the paper feeding box part can be connected with the feeding synchronous belt, and the packages can be placed on each station of the conveying surface of the feeding synchronous belt manually or automatically, and then the packages are pushed into the open box body through the pushing-into-box assembly.

[0066] The feeding part of the present invention can be arranged as follows: In some embodiments, as Figure 6As shown, the feeding part includes a feeding timing belt assembly, a picking assembly 205 and a storage assembly. The picking assembly 205 is arranged on one side of the storage assembly, and the feeding timing belt assembly is located on one side of the picking assembly. During feeding, the picking assembly takes the packaged material from the storage assembly and places it on the feeding timing belt assembly, and the packaged material is transported to the pushing-in-box assembly 107 of the paper feeding box part via the feeding timing belt assembly, and the packaged material is pushed into the open paper box by the pushing-in-box assembly 107.

[0067] In some embodiments, the material storage assembly includes a material storage trough 203, the material storage trough 203 has an inclined material storage plate, and the packages 902 are vertically stacked on the material storage plate;

[0068] The feeding synchronous belt assembly includes a feeding conveyor belt 204, and the feeding conveyor belt 204 is located on the left side of the storage tank 203;

[0069] The material picking assembly includes a material picking rocker 2051, which is located at the front side of the feeding conveyor belt 204 and the material storage trough 203. One end of the material picking rocker 2051 is connected to the material picking rocker shaft, and the other end is connected to the material suction shaft. The material picking rocker shaft is provided with a first material picking synchronous wheel 20521 and a second material picking synchronous wheel 20522, and the material suction shaft is provided with a third material picking synchronous wheel 20523. The first material picking synchronous wheel 20521 is connected to the material tipping motor 2054 through the first material picking synchronous belt 20531, and the second material picking synchronous wheel 20522 is connected to the third material picking synchronous wheel 20523 through the second material picking synchronous belt 20532; the rotating shaft of the material tipping motor 2054 can be connected to the fourth material picking synchronous wheel 20524, and one end of the first material picking synchronous belt 20531 is sleeved on the fourth material picking synchronous wheel 20524. A material taking plate 2055 is provided on the material suction rotating shaft, and at least two material taking suction cups are provided on the material taking plate 2055 .

[0070] Specifically, when the rotating shaft of the material flipping motor 2054 rotates in the forward direction, it drives the first material picking synchronous wheel 20521 to rotate, thereby driving the rotating shaft of the material picking rocker arm to rotate. The rotation of the rotating shaft of the material picking rocker arm drives the second material picking synchronous wheel 20522 to rotate, thereby driving the third material picking synchronous wheel 20523 to rotate through the second material picking synchronous belt 20532, and finally flipping the material picking plate 2055.

[0071] In order to realize the reciprocating swing of the material-collecting swing rod between the feeding conveyor belt and the material storage plate, the following configuration can be made: the material-collecting swing rod 2051 is connected downwardly to the material-collecting push rod (not shown in the figure), the material-collecting push rod is connected to the material-collecting motor swing rod (not shown in the figure), and the material-collecting motor swing rod is connected to the material-collecting motor (not shown in the figure), wherein the material-collecting motor and the material-collecting motor swing rod can be arranged below the bottom plate 201, and the material-collecting push rod extends from the bottom to the top above the bottom plate 201 and then connects to the material-collecting swing rod 2051. When the material-collecting motor is working, it drives the material-collecting motor swing rod to rotate, drives the material-collecting push rod to reciprocately push the material-collecting swing rod 2051, and the reciprocating swing of the material-collecting swing rod 2051 causes the material-collecting plate 2055 to reciprocate along an arc path between the material storage plate 203 and the feeding conveyor belt 204, thereby transferring the packaged material from the material storage plate 203 to the feeding conveyor belt 204.

[0072] At the same time, the second material picking synchronous wheel 20522 rotates and drives the material suction shaft to rotate, so that the material picking plate 2055 also turns over. When the material picking plate 2055 is moved to the discharge port of the material storage tank 203 with the reciprocating swing of the material picking swing rod 2051, the material picking plate 2055 turns over so that the suction cup surface of the material picking suction cup faces the packaging material pile stacked at the discharge port and the suction cup surface is in contact with the surface of the packaging at the front end of the material pile. The material picking suction cup generates negative pressure on the suction cup surface through a cylinder or other equipment to suck up the packaging at the front end.

[0073] After the pressure change of the cylinder of the picking suction cup shows that it has sucked the package, the picking motor rotates in the opposite direction, so that the picking swing rod 2051 will swing the picking plate 2055 that has sucked the package in the opposite direction along the arc path to above the conveying surface of the feeding conveyor belt 204. After the cylinder is released, the picking suction cup places the package on the conveying surface.

[0074] In the above embodiments, the material picking rocker arm rotating shaft and the material suction rotating shaft can both be set to be parallel to the bottom plate 201 and perpendicular to the material picking rocker arm 2051, and located on the same side of the material picking rocker arm 2051, and the first material picking synchronous wheel 20521, the second material picking synchronous wheel 20522 and the third material picking synchronous wheel 20523 are located on the other side of the material picking rocker arm 2051.

[0075] The material taking swing rod 2051 is rotatably connected to the bracket or bracket plate of the feeding part through the material taking swing rod rotating shaft.

[0076] At least two storage shelves 2041 can be set on the feeding conveyor belt 204. The storage shelves 2041 are used to place packages on their upper surface. At least two storage shelves 2041 are spaced apart along the length direction of the conveying surface of the feeding conveyor belt 204. The distance between adjacent storage shelves 2041 is greater than the width of the packages, so as to prevent adjacent packages from contacting each other after the packages are placed on the storage shelves. Here, the purpose of setting the storage shelves is to allow the packages to be higher than a certain height relative to the conveying surface of the feeding conveyor belt, so as to provide operational convenience for the subsequent pushing process. If the packages are placed directly on the conveying surface, the working accuracy requirements of the pushing and feeding assembly of the paper feeding box part will be very high, and it is also easy to contact the conveying surface when pushing the materials, which may cause equipment failure.

[0077] In some preferred embodiments, the storage shelf 2041 can be connected to a cylinder, and a negative pressure environment can be formed on the surface of the storage shelf through the cylinder. For example, a small hole is opened on the upper surface of the storage shelf to provide a negative pressure environment weaker than the negative pressure during material removal, so that the packages placed thereon are not easy to fall off the storage shelf when the feeding conveyor belt is working. Figure 6 In the structure shown, the storage shelf 2041 is configured as two vertical plates in a group that are parallel to each other and perpendicular to the conveying surface of the feed conveyor belt. A suction nozzle can be set between the two vertical plates in the group to generate a negative pressure environment between the two vertical plates in the group to generate a certain adsorption force on the packages placed thereon to prevent them from falling during movement.

[0078] In addition, all storage shelves can share an independent air cylinder to provide the air pressure required to form a negative pressure environment on their surfaces.

[0079] In some embodiments, Fig. 9 As shown, the suction box assembly includes a suction box motor 1048, a suction box motor swing rod 1047, a suction box push rod 1046, a suction box swing rod 1041, a suction box swing rod rotating shaft 1042, a suction box plate rotating shaft and a suction box plate 1043.

[0080] The motor shaft of the suction box motor 1048 is connected to the suction box motor swing rod 1047, the suction box motor swing rod 1047 is connected to the suction box push rod 1046, the suction box push rod 1046 is connected to the suction box swing rod 1041, one end of the suction box swing rod 1041 is connected to the suction box swing rod rotating shaft 1042, and the other end is connected to the suction box plate rotating shaft. The suction box plate 1043 is set on the suction box plate rotating shaft, and the suction box suction cup 1044 is provided on the suction box plate 1043;

[0081] The first suction box synchronous wheel 10451 and the second suction box synchronous wheel 10452 are provided on the suction box swing lever rotating shaft 1042, and the third suction box synchronous wheel 10453 is provided on the suction box plate rotating shaft. The first suction box synchronous wheel 10451 is connected to the flip motor 1046 through the first suction box synchronous belt (not shown in the figure), and the second suction box synchronous wheel 10452 is connected to the third suction box synchronous wheel 10453 through the second suction box synchronous belt (not shown in the figure). It should be noted that, in consideration of the layout space, the present invention can adopt a hidden layout mode in which the flip motor 1046 is installed directly below the paper box placement slot. In this layout, the fourth suction box synchronous wheel 10454 can be provided on the rotating shaft of the flip motor 1046, and then connected to the first suction box synchronous wheel 10451 through a synchronous belt to drive the wheel to rotate.

[0082] When the box suction assembly of the present invention is working, the box suction motor 1048 reciprocates to push the box suction push rod 1046 after the box suction motor swing rod 1047 swings, and the box suction push rod 1046 pushes the box suction swing rod 1041, so that the box suction plate 1043 reciprocates along the arc path, so that the suction cup 1044 approaches the paper box placement slot to take the material or swings to the box pushing assembly; the flip motor 1046 drives the first box suction synchronous wheel 10451 to rotate, so that the second The suction box synchronous wheel 10452 also rotates synchronously on the same axis. The second suction box synchronous wheel 10452 drives the third suction box synchronous wheel 10453 to rotate through the second suction box synchronous belt, so that the suction box plate 1043 rotates around the suction box plate rotation axis, thereby realizing the flipping of the suction box plate 1043 and the suction cup 1044 thereon. When the suction box plate 1043 is pushed by the suction box push rod 1046 to make a reciprocating swing, the suction box plate 1043 also performs periodic flipping during the reciprocating swing cycle. One end of the swing path of the suction box plate 1043 is located on one side of the end of the unloading rack (the left side of the low position end of the inclined unloading rack). When swinging, the suction box plate shaft rotates to make the plate surface of the suction box suction cup 1044 on the suction box plate 1043 face the paper box prototype 901 on the unloading rack, and make the surface of the suction cup fit the surface of the paper box prototype 901, and then when the cylinder works, the suction box suction cup 1044 absorbs the paper box prototype 901; the suction box swing rod 1041 swings in the opposite direction to absorb the absorbed paper box prototype The prototype 901 is dragged out from the unloading rack of the paper box placement slot, and during the dragging process, the paper box prototype 901 is unfolded from the pressed sheet structure to an open box body structure after being blocked by the baffle 1033, and the suction box swing rod 1041 continues to swing in the opposite direction to send the open box body to the box pushing assembly 105, and during the rotation of the suction box swing rod shaft, the disk surface of the suction box suction cup 1044 on the suction box plate 1043 is flipped to face the disk surface of the suction cup on the box pushing assembly 105 when it is located at the box pushing assembly 105. When the box suction plate 1043 swings in the opposite direction along the arc path to the box pushing assembly 105, the box suction cup 1044 on the box suction plate 1043 and the suction cup on the box pushing assembly 105 are just located on the left and right sides of the open box body 901-1. At this time, the cylinder of the box suction cup 1044 is released, and the cylinder of the suction cup on the box pushing assembly 105 works to adsorb the open box body 901-1 and push it into the upper and lower synchronous box feeding assembly; after the box pushing assembly 105 is pushed into place, the suction cup can be released to make the open box body previously adsorbed fall into the conveying station of the upper and lower synchronous box feeding assembly.

[0083] Fig. 9 In the structure shown, in order to clearly display the structure, part of the bottom plate 102 is cut off, and part of the opening box body 901-1 is cut off to expose the suction cup on the box pushing assembly 105 covered by it.

[0084] In some embodiments, Fig.10As shown, the box pushing assembly 105 includes a box pushing synchronous belt 1051, a box pushing connecting rod 1052, a box pushing guide rail 1053, a box pushing slider 1054, and a box pushing suction cup seat 1055. The box pushing suction cup seat 1055 is provided with at least two box pushing suction cups 1056 for receiving the open box body 901-1 transferred from the suction box assembly. The box pushing slider 1054 is inserted into the box pushing guide rail 1053 and moves back and forth along the length of the box pushing guide rail 1053. The upper end of the box pushing connecting rod 1052 is connected to the box pushing slider 1054, and the lower end is connected to the box pushing synchronous belt 1051 through a box pushing connecting rod seat 1057. When the box pushing synchronous belt 1051 moves, the box pushing connecting rod seat 1057 is moved at the same time, so that the box pushing connecting rod 1052 is moved and then the box pushing slider 1054 is moved through it, so that it moves back and forth along the box pushing guide rail 1053.

[0085] The box-pushing sucker seat 1055 is connected to the box-pushing slider 1054 through the box-pushing adjusting seat 1058. When the box-pushing slider 1054 moves, the box-pushing sucker seat 1055 is driven to move back and forth linearly through the box-pushing adjusting seat 1058. Further, for the convenience of structural manufacturing and installation and maintenance, the box-pushing slider 1054 is arranged on the box-pushing slider seat 1059, the box-pushing adjusting seat 1058 is indirectly connected to the box-pushing slider 1054 through the box-pushing slider seat 1059, and the box-pushing connecting rod 1052 is indirectly connected to the box-pushing slider 1054 through the box-pushing slider seat 1059.

[0086] It should be noted that the box pushing synchronous belt 1051 is driven by the motor 10511, the main synchronous wheel 10512 and the slave synchronous wheel 10513 to move. In order to avoid damaging the equipment structure due to excessive movement, the moving stroke of the box pushing synchronous belt 1051 is set to be smaller than the length of the slot on the base plate 102 through which the box pushing connecting rod 1052 passes. That is to say, its movement only ensures that the box pushing connecting rod 1052 moves back and forth in a straight line.

[0087] In some preferred embodiments, the push box adjustment seat 1058 adopts an L-shaped adjustment seat, which includes a horizontal part and a vertical part. The horizontal part and the vertical part are vertically connected to each other. Both the horizontal part and the vertical part are provided with waist-shaped grooves, which are convenient for adjusting the installation position of the horizontal part on the push box slider through the waist-shaped groove on the horizontal part, thereby adjusting the left and right position of the push box suction cup 1056, so that it is convenient to receive the open box body 901-1 after cooperating with the suction box assembly, and the waist-shaped groove on the vertical part is used to adjust the up and down position of the push box suction cup 1056, so that it is convenient to receive the open box body 901-1 after cooperating with the suction box assembly.

[0088] The push-in box assembly of the present invention is arranged in the following structure: In some embodiments, as Figure 5As shown, the material pushing into the box assembly includes a material pushing into the box slider 1071, a material pushing into the box timing belt 1072 and a material pushing into the box motor 1073. One end of the material pushing into the box timing belt 1072 is connected to the rotating shaft of the material pushing into the box motor 1073 through a synchronous wheel, and the other end is connected to another synchronous wheel. The material pushing into the box slider 1071 is connected to the material pushing into the box timing belt 1072, and when the material pushing into the box timing belt 1072 moves, it moves along with it to realize reciprocating linear motion in the front and back directions. A push handle is provided on the material pushing into the box slider. When the feeding conveyor belt transports the packages to the material pushing into the box station, after the material pushing into the box slider 1071 is pushed out, the packages on the storage shelf 2041 are pushed into the open box body through the push handle.

[0089] The length adjustment assembly of the present invention can be arranged in the following structure: In some embodiments, as Figure 5 , Fig.14 As shown, the length adjustment assembly includes an upper and lower synchronous belt connecting rod 1065, a length adjustment screw rod 106301 and a length adjustment motor 106302. The rotating shaft of the length adjustment motor 106302 is connected to the length adjustment screw rod 106301 and drives it to rotate. The length adjustment screw rod 106301 passes through the lower synchronous belt front baffle plate 106201 and the lower synchronous belt rear baffle plate 106202 in turn. The length adjustment screw rod 106301 is threadedly connected with the lower synchronous belt front baffle plate 106201, so that when the length adjustment screw rod 106301 rotates, the lower synchronous belt front baffle plate 106201 performs a linear reciprocating motion along the length direction of the length adjustment screw rod 106301.

[0090] The upper and lower synchronous belt connecting rods 1065 connect the upper synchronous belt front baffle 106101 and the lower synchronous belt front baffle 106102, so that when the lower synchronous belt front baffle 106201 moves, the upper synchronous belt front baffle 106101 is driven to move synchronously.

[0091] The upper and lower synchronous belt connecting rods in the present invention can be arranged according to the following structure: Fig.11 As shown, the upper and lower synchronous belt connecting rods 1065 include an upper connecting end 106501, a lower connecting end 106502, upper and lower connecting parts 106503, a connecting rod slider 106504, and a connecting rod slide rail 106505, wherein:

[0092] One end of the upper connection end 106501 is connected to the front baffle of the upper synchronous belt, and a fastener through hole is provided on the upper connection end 106501 for passing the fastener during connection, and the other end of the upper connection end 106501 is fixedly connected to the connecting rod slider 106504;

[0093] One end of the lower connecting end 106502 is connected to the lower synchronous belt front baffle, which is provided with a fastener through hole for passing the fastener during connection, and the other end of the lower connecting end 10502 is fixedly connected to the upper and lower connecting parts 106503;

[0094] The upper and lower connecting parts 106503 are vertically arranged, and a connecting rod slide rail 106505 is fixed thereon from top to bottom. The connecting rod slider 106504 is slidably connected to the connecting rod slide rail 106505, so that the connecting rod slider 106504 can make reciprocating linear motion in the up and down directions along the connecting rod slide rail 106505, so that the upper and lower synchronous belt connecting rods not only connect the upper synchronous belt front baffle 106101 and the lower synchronous belt front baffle 106201, so that the two can make reciprocating linear motion synchronously along the front and rear directions when the length is adjusted by the length adjustment component, but also can make the upper synchronous belt front baffle 106101 relative to the lower synchronous belt front baffle 106201 The front baffle will not be displaced in the front and rear directions during the up and down lifting movement when the height is adjusted by the height adjustment component.

[0095] The threaded connection structure between the length adjustment screw 106301 and the lower synchronous belt front baffle 106201 can be regarded as a baffle structure of the lower synchronous belt front baffle 106201 being threadedly connected to a slider on the length adjustment screw 106301, so that when the screw rotates, the lower synchronous belt front baffle 106201 acting as a slider converts the rotation along the screw into linear reciprocating motion, thereby realizing the reciprocating linear motion of the lower synchronous belt front baffle in the front and rear directions relative to the rear baffle.

[0096] Specifically, the threaded connection structure of the length adjustment screw 106301 and the lower synchronous belt front baffle 106201 can be set as follows: a flange is set where the length adjustment screw 106301 passes through the lower synchronous belt front baffle 106201, and a slider is embedded in the flange. The slider has an internal thread, so that the slider and the length adjustment screw 106301 are threadedly connected.

[0097] In addition, on the rear outer wall of the lower synchronous belt rear baffle 106202, a flange is provided at the protruding end of the length adjusting screw 106301 for closing the protruding end of the length adjusting screw 106301, in which a bearing is embedded, and the protruding end of the length adjusting screw 106301 is inserted into the bearing therein; a screw base 106303 can be provided at the other end of the length adjusting screw 106301, in which a bearing is also embedded, so that the end of the length adjusting screw 106301 is inserted into the bearing therein, ensuring that the end of the length adjusting screw 106301 can be rotated while limiting its movement in the forward and backward directions.

[0098] The connection between the length adjustment screw 106301 and the length adjustment motor 106302 can be a linear connection. In this case, the screw base in the aforementioned embodiment is not set, and the motor is set at the position of the screw base. When the linear connection is used, the motor shaft and the screw can be connected through a coupling so that the axes of the two are on the same straight line.

[0099] Alternatively, the length adjustment screw rod 106301 and the length adjustment motor 106302 can be connected by bevel gears to realize the vertical connection between the screw rod and the motor shaft, which can not only save equipment layout space, but also ensure the smoothness of transmission and the protection of the motor. When setting, bevel gears are sleeved on the motor shaft and the screw rod and meshed. Figure 5 This arrangement is shown in the structure shown, but the bevel gear is not shown in the figure.

[0100] It should be noted that in order to facilitate the smooth movement of the lower synchronous belt front baffle 106201 and the balanced force on the left and right ends, a lower length adjustment guide rail 106304 can be set. The lower length adjustment guide rail 106304 passes through the lower synchronous belt front baffle 106201 and the lower synchronous belt rear baffle 106202 in turn. Flanges are set at the passing points and fixed to the outer walls of the baffles, and bearings are set in the flanges. When the lower length adjustment guide rail 106304 passes through each baffle, it actually passes through the bearings at the corresponding positions, so that when the lower synchronous belt front baffle 106201 moves, the lower length adjustment guide rail 106304 provides guidance and support during movement.

[0101] In addition, an upper length adjustment guide rail can also be set at the upper synchronous belt assembly to provide guidance and support for the movement of the upper synchronous belt front baffle 106101.

[0102] For the scenario where the length of the upper and lower synchronous box feeding assembly 106 is relatively long, the present invention can be arranged in the following structure: at least two length adjustment motors 106302 can be arranged, and the length adjustment screw rods 106301 cooperating therewith are also arranged in a corresponding number, and each length adjustment motor 106302 drives a length adjustment screw rod 106301. By arranging multiple length adjustment motors 106302 at intervals on the left and right and then driving the corresponding length adjustment screw rods 106301 to act synchronously, force is applied at different positions of the lower synchronous belt front baffle plate 106201 to cause it to displace relative to the lower synchronous belt rear baffle plate 106202, and the displacement direction is along the length direction of the lower length adjustment guide rail (or the length adjustment screw rod 106301). Figure 5 In the structure shown, another length adjustment screw rod 106301-1 is shown on the left side of the lower length adjustment guide rail 106304, but the motor matched therewith is not shown.

[0103] Correspondingly, at least two upper and lower synchronous belt connecting rods 1065 may be provided, and adjacent upper and lower synchronous belt connecting rods 1065 are arranged at intervals in the left-right direction and connected to different positions of the lower synchronous belt front baffle 106201 and the upper synchronous belt front baffle 106101;

[0104] Correspondingly, at least two upper length adjustment guide rails may be provided, and adjacent upper length adjustment guide rails may be spaced apart in the left-right direction.

[0105] The height adjustment assembly of the present invention can be arranged as follows: In some embodiments, as Figure 5 As shown, the height adjustment component includes a height adjustment motor 106402 and a height adjustment screw rod 106401, the height adjustment screw rod 106401 is vertically arranged, the height adjustment motor 106402 is connected to the height adjustment screw rod 106401 and drives it to rotate, the height adjustment screw rod 106401 is threadedly connected to the height adjustment fixing seat 106403, one end of the height adjustment fixing seat 106403 is fixedly connected to the upper synchronous belt rear baffle 106102, when the height adjustment motor 106402 drives the height adjustment screw rod 106401 to move, the rotation of the height adjustment screw rod 106401 causes the height adjustment fixing seat 106403 threadedly connected thereto to perform a linear reciprocating motion up and down, at which time the upper synchronous belt rear baffle 106102 is raised or lowered;

[0106] The height adjustment fixed seat 106403 is connected to the upper length adjustment guide rail 106404, and an upper adjustment slider seat 106405 is provided on the upper synchronous belt front baffle 106101. The upper adjustment slider seat 106405 is provided with an opening, in which an upper adjustment slider is provided. The upper length adjustment guide rail 106404 crosses the opening of the upper adjustment slider seat 106405 and is slidably connected with the upper adjustment slider.

[0107] Specifically, the upper adjusting slider seat is fixed on the front outer wall of the upper synchronous belt front baffle 106101, and an opening is provided on the upper adjusting slider seat for the upper length adjusting guide rail to pass through horizontally in the horizontal direction. The upper adjusting slider is fixedly arranged in the opening. The upper adjusting slider can be provided with a groove, and a guide surface protruding facing the direction of the groove is provided on the upper length adjusting guide rail corresponding to the groove, so that the groove and the guide surface are mutually engaged, so that when the upper synchronous belt front baffle 106101 makes a reciprocating linear movement in the front and rear directions, the upper adjusting slider can make a reciprocating linear movement along the guide surface of the upper length adjusting guide rail 106404. At the same time, since the upper length adjusting guide rail 106404 is restricted by the opening structure of the upper adjusting slider seat, when the upper length adjusting guide rail 106404 makes an up and down lifting movement with the height adjustment fixed seat 106403, it drives the upper synchronous belt front baffle 106101 to also make a synchronous lifting movement.

[0108] In addition, in order to facilitate the guidance and lateral support during lifting, the following structure can be set: a vertical height adjustment guide rail is set at the end of the height adjustment fixed seat 106403 that is not connected to the upper synchronous belt rear baffle 106102, and then a height adjustment guide slider corresponding to the guide rail is fixed on the rear side of the height adjustment guide rail, so that the slider and the guide rail are slidably connected. When the height adjustment fixed seat 106403 is lifted and lowered, the height adjustment guide rail moves vertically, and through cooperation with the height adjustment guide slider, it provides guidance and lateral support for lifting. ( Fig.14The height adjustment guide rail structure is shown in the figure, but not marked, and is arranged on the front side of the bracket plate 1066, between the front side and the height adjustment fixing seat 106403)

[0109] In addition, at least two of the height adjustment guide sliders can be arranged at intervals along the direction of the height adjustment guide rail, and can be arranged at intervals up and down.

[0110] As shown in the structure shown in the figure, the height adjustment fixed seat 106403 has a vertical part and a horizontal part. The horizontal part is provided with a hole for the height adjustment screw rod 106401 to pass through from top to bottom. One end of the horizontal part is fixedly connected to the upper synchronous belt rear baffle 106102, and the other end is connected to the vertical part (as shown in the structure shown in the figure, since one end of the horizontal part is connected to the middle position of the vertical part, its structural appearance is a T-shaped structure lying on one side), and a height adjustment guide rail is provided on the vertical surface of the vertical part.

[0111] In the present invention, the installation and lifting structure of the height adjustment motor can be realized by the following structural setting: the height adjustment motor 106402 is vertically arranged on a horizontally placed motor mounting plate, and after its vertically upward motor shaft passes through the hole located on the motor mounting plate, an active synchronous wheel 1064021 is arranged at the end of the motor shaft, and a driven synchronous wheel 1064022 is arranged on the upper plate surface of the motor mounting plate. The active synchronous wheel 1064021 and the driven synchronous wheel 1064022 are connected to drive the synchronous belt and rotate synchronously. After the height adjustment screw rod 106401 is vertically arranged, its top end passes through the motor mounting plate and is connected to the driven synchronous wheel 1064022, and its lower end is fixed in a fixed seat, and the fixed seat can also be fixedly connected to the motor mounting plate by a bracket or other structure, such as Fig.14 In the structure shown, one side of the motor mounting plate is fixedly connected to a vertically arranged bracket plate 1066, and the fixing seat can be fixed on the bracket plate 1066 (located on the front side of the bracket plate, not shown in the figure). In addition, when a height adjustment guide slider is provided, the height adjustment guide slider can also be fixedly connected to the bracket plate 1066. In order to reduce weight, the bracket plate 1066 can adopt a hollow design, and a plurality of weight-reducing openings are provided on it.

[0112] In order to facilitate the tensioning of the driving synchronous belt of the motor, at least two tensioning wheels can be arranged on the upper plate surface of the motor mounting plate according to the layout position.

[0113] In order to achieve structural stability during lifting, the present invention can be further configured as follows:

[0114] Another driven synchronous wheel 1064023 is arranged on the motor mounting plate, and the two driven synchronous wheels are arranged on the upper surface of the motor mounting plate at intervals in the left and right directions. Another height adjustment screw is connected through another driven synchronous wheel 1064023, and another height adjustment fixed seat is arranged in conjunction with the other height adjustment screw, and is fixedly connected to the synchronous belt rear baffle 106102, thereby constructing two sets of height adjustment structures spaced apart from each other on the left and right sides, and the same height adjustment motor is used to drive the synchronous lifting action.

[0115] In conjunction with the two sets of height adjustment structures, another upper length adjustment guide rail can be connected to another height adjustment fixed seat, another upper adjustment slider seat can be arranged in conjunction with the other upper length adjustment guide rail, and another upper adjustment slider can be arranged on the other upper adjustment slider seat, so that the other upper adjustment slider is slidably connected to the other upper length adjustment guide rail. This ensures that support is provided during lifting and lowering, and can provide a more stable support effect for the movement process of the upper synchronous belt front baffle 106101 that moves back and forth linearly.

[0116] In the process of picking up and delivering the paper box by the suction box assembly, the paper box is stretched from a flat pressed sheet structure to an open box body structure, and then when being delivered in the delivery station of the upper and lower synchronous box delivery assemblies, a series of actions such as feeding, folding tongues, and closing tongues are performed to form a closed box body and then delivered to the next packaging link, wherein the actions of folding tongues and closing tongues are realized by the closing tongue assembly, such as Figure 5 , Fig.12 As shown, in some embodiments, the tongue closing assembly includes a small tongue closing portion 1081 and a large tongue closing portion 1082. The small tongue closing portion 1081 is used to flip up the top cover located at the front side of the paper box and the bottom cover located at the rear side of the paper box to a certain angle to facilitate the subsequent large tongue closing operation. The large tongue closing portion 1082 is used to cover the top cover and the bottom cover of the paper box on the front and rear side openings of the paper box.

[0117] The large closing tongue 1082 is located on the left side of the small closing tongue 1081, so that when the paper box is transported from right to left, it first passes through the small closing tongue 1081 to close the small tongue, and then passes through the large closing tongue 1082 to close the large tongue. Fig.12 As shown, a small closing tongue and a large closing tongue are respectively provided on the front and rear sides of the upper and lower synchronous box feeding components. The two small closing tongues 1081 are respectively located on the front side of the lower synchronous belt front baffle 106201 and the rear side of the lower synchronous belt rear baffle 106202. The two can be set to be staggered left and right. As shown in the figure, the small closing tongue located on the front side is set on the right side of the small closing tongue located on the rear side (due to Fig.12 The two closing tongues 1082 are respectively located on the front side of the lower synchronous belt front baffle 106201 and the rear side of the lower synchronous belt rear baffle 106202, and are arranged face to face.

[0118] like Fig.13As shown, the small tongue portion 1081 includes a small tongue plate 108101, a small tongue shaft 108102, a small tongue shaft seat 108103, a small tongue pull rod 108104, a small tongue wheel 108105 and a small tongue wheel shaft seat 108106. The small tongue shaft seat 108103 and the small tongue wheel shaft seat 108106 are fixed on the mounting base. The small tongue shaft 108102 is vertically arranged, and its upper end is connected to the small tongue plate 108101, and its lower end passes through the small tongue shaft seat 10813 and then connects to the small tongue pull rod 108104 through the swing block 108107 at its end. The other end of the small tongue pull rod 108104 is connected to the small tongue wheel 108105, and the wheel passes through the small tongue wheel shaft seat 108106 in the axial direction and then passes through the bevel gear set (Figure The driving shaft (not shown in the figure) connected to the lower synchronous belt assembly, the bevel gear set includes a bevel gear sleeved on the driving shaft and another bevel gear sleeved on the shaft of the closing tongue wheel. After the two bevel gears are meshed, the effect of transmitting the power of the driving shaft to the closing tongue is achieved. One end of the closing tongue plate 108101 is located on one side of the upper and lower synchronous box feeding assembly. For example, in the structure shown in the figure, the closing tongue plate of the front closing tongue is located in front of the front baffle 106201 of the lower synchronous belt, so that when the open box structure of the paper box is being transported, the closing tongue plate in synchronous rotation closes the small tongue plate of the paper box when passing through the position of the closing tongue plate. When the closing tongue plate is in motion, it swings back and forth through the action of the closing tongue wheel, thereby realizing the successive closing of the small tongue plates on both sides of the same opening of the paper box. The front and rear closing tongues are connected to the driving shaft of the lower synchronous belt assembly through the bevel gear set.

[0119] In addition, in order to ensure smooth movement of the closing tongue, a bearing can be embedded in the closing tongue shaft seat to ensure smooth rotation of the closing tongue shaft.

[0120] It should be noted that the mounting base for fixing the small tongue shaft seat generally refers to a structure such as a frame that does not move during the operation of the equipment, such as the baffles of each synchronous belt. Here, the small tongue shaft seat and the small tongue runner shaft seat can be fixed on the front baffle of the lower synchronous belt or the rear baffle of the lower synchronous belt.

[0121] Any closing tongue portion includes a folding tongue plate 10821 and a closing tongue plate 10822. The folding tongue plate 10821 is located on the right side of the closing tongue plate 10822. The folding tongue plate 10821 adopts a folding tongue plate with a reciprocating linear movement function along the front and rear directions, and the closing tongue plate 10822 adopts a closing tongue plate with a reciprocating linear movement function along the front and rear directions.

[0122] Specifically, the function of the reciprocating linear movement of the folding tongue plate 10821 and the closing tongue plate 10822 can be realized after the following structural arrangement: the folding tongue plate 10821 or the closing tongue plate 10822 is installed on a tongue-closing slider 10823, and the slider is slidably connected to a tongue-closing slide rail 10824 arranged in the front-to-back direction. The slider is connected to a driving mechanism 10825 such as a motor or a cylinder through a connecting rod and other mechanisms. After the driving mechanism 10825 drives the connecting rod to perform a linear motion, it pushes the tongue-closing slider 10823 to perform a reciprocating linear motion along the tongue-closing slide rail 10824, thereby driving the folding tongue plate 10821 or the closing tongue plate 10822 to perform a reciprocating linear motion.

[0123] Furthermore, the folding tongue plate 10821 and the closing tongue plate 10822 are arranged on the same connecting plate 10826, which is connected to the tongue closing slider, and the tongue closing slider is slidably connected to the tongue closing slide rail. The connecting plate 10826 is connected to a driving mechanism 10825 that pushes it to perform linear motion, such as a motor, a cylinder or a hydraulic cylinder, through a connecting rod mechanism, so as to realize the synchronous action of pushing the folding tongue plate or the closing tongue plate through a single driving mechanism. Since the folding tongue plate and the closing tongue plate are arranged at intervals in the left and right directions, they can perform two actions as the paper box with the unclosed tongue moves from right to left on the upper and lower synchronous box feeding components, thereby realizing the folding tongue action of the folding tongue plate and the closing tongue action of the closing tongue plate in turn.

[0124] As attached to this application Fig.13 In the structure shown, the folding tongue plate and the closing tongue plate are arranged on the same connecting plate 10826, and two sliders are fixedly connected to the bottom of the connecting plate. The two sliders are arranged at intervals on the left and right, and any slider is slidably connected to a slide rail arranged in the front-to-back direction. A connecting rod mechanism is arranged between the two sliders, and one end of the connecting rod mechanism is connected to the lower surface of the connecting plate 10826, and the other end of the connecting rod mechanism is connected to the surface of a rotating wheel through a bearing. The center of the rotating wheel is sleeved on the shaft of a driving motor. When the shaft of the driving motor rotates, the rotating wheel rotates accordingly, and the connection point between the bearing and the rotating wheel rotates around the center of the rotating wheel, and finally the connecting rod mechanism pushes the connecting plate to perform reciprocating linear motion forward and backward along the length direction of the slide rail. The driving mechanism can be arranged on a mounting plate, and the mounting plate is fixedly connected to a mounting base, for example, Fig.13 In the structure shown, the drive mechanism mounting plate is fixedly connected to the front baffle of the lower synchronous belt, the drive mechanism is located below the mounting plate, and the rotating wheel is located above the mounting plate.

[0125] In the present invention, the closing tongue operation is a passive operation, which is caused by the inertia force during the process of the paper box being transported by the conveying surface of the upper and lower synchronous box feeding components. When the top cover and the bottom cover of the paper box contact the closing tongue, they are pushed up to a certain angle by the reaction force.

[0126] In summary, the present invention realizes the function of the paper supply box part by setting a sucking box assembly, a pushing box assembly, an upper and lower synchronous box feeding assembly, and a material pushing box assembly, and realizes the automatic adjustment of the upper synchronous belt assembly and the lower synchronous belt assembly corresponding to paper boxes of different specifications and sizes through the upper and lower synchronous box feeding assembly with a length and height adjustment assembly, so that the mechanism body can correspond to the box feeding requirements of paper boxes of different specifications and sizes according to actual needs. Among them, when the length adjustment assembly is working, the spacing distance (front and back direction) between the two baffles of the upper synchronous belt assembly is increased or decreased, and at the same time, the spacing distance (front and back direction) between the two baffles of the lower synchronous belt assembly is also synchronously increased or decreased by the same distance, so as to correspond to paper boxes of different lengths; when the height adjustment assembly is working, the upper synchronous belt assembly is lifted or lowered as a whole relative to the lower synchronous belt assembly, so that the spacing distance (up and down direction) between the upper synchronous belt assembly and the lower synchronous belt assembly is increased or decreased, so as to correspond to paper boxes of different heights; when the upper synchronous belt assembly and the lower synchronous belt assembly are misaligned, the width of the placement station on the conveying surface can be adjusted, so as to correspond to paper boxes of different widths. It should be noted that the upper and lower synchronous belt assemblies in the present application run in opposite directions when working to ensure the normal delivery of the paper box. For example, the upper synchronous belt assembly rotates clockwise, and the lower synchronous belt assembly rotates counterclockwise at the same rate to ensure that the paper box is normally delivered from right to left. In addition, the control system of the mechanism can be coordinated to produce corresponding control instructions for different specifications and sizes, and corresponding control buttons can be configured. When different control buttons are manually pressed, the equipment automatically controls the forward and reverse rotation of the length adjustment assembly, the height adjustment assembly, and the upper and lower synchronous belt assemblies, so that the upper and lower synchronous box delivery assemblies are adjusted to an operating state suitable for the new delivery of the paper box.

[0127] In addition, the power supply of each component of the present application can be realized by a servo motor, thereby further improving the motion accuracy of each structure in the present application and ensuring the real-time nature of the motion. For example, the active shaft drive motor of the synchronous belt of the upper and lower synchronous box feeding components, the length adjustment motor and the height adjustment motor, the material taking motor and the material turning motor of the material storage component, the box suction motor and the flipping motor of the box suction component, the material pushing motor of the box pushing component, and the drive motor of the tongue closing part, etc.

[0128] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
