Description

Technical Field

[0001] The invention relates to packaging equipment, in particular to an automatic box packing machine for pen-shaped materials. Background Art

[0002] Packaging is often the last step in the production process, and the packaging process requires the use of cartoning equipment to maximize packaging efficiency. Cartoning equipment is an automated device that automatically loads the goods to be packaged into a folding box and completes the box closing action. Some fully functional automatic cartoning equipment also has additional functions such as affixing sealing labels or performing heat shrink wrapping.

[0003] The existing box loading equipment includes a bottom buckle mechanism, which is used to realize the mutual folding and locking between the bottom tongues of the paper box. The bottom buckle mechanism is limited by the folding type of the paper box and the shape and number of the bottom tongues. If you want to complete the sequential folding between the bottom tongues, you have to divide it into many steps and fold it in sequence. In the prior art, in order to realize the sequential folding of the bottom tongues, it is usually necessary to set up many independent drive sources to drive them in sequence to complete the folding steps. This also means that if there are many folding steps for the paper box, more independent drive sources corresponding to the steps are required. This greatly increases the production cost of the equipment. In addition, the use of independent drive sources also increases the occurrence of equipment failure rate, which also greatly affects the reliability of equipment operation. Summary of the invention

[0004] The object of the present invention is to provide an automatic box packing machine for pen-shaped materials, which has low production cost and more reliable equipment operation.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic cartoning machine for pen-shaped materials, comprising a carton storage conveying mechanism, a feeding mechanism for grabbing the carton output by the carton storage conveying mechanism and transmitting it, an expansion mechanism cooperating with the feeding mechanism to open the carton, and a conveying mechanism for transmitting the opened carton, a bottom buckling mechanism for folding and locking the bottom tongue of the carton, a pen-shaped feeding mechanism for feeding the inner cavity of the carton, and a covering mechanism for covering the cover of the carton are sequentially arranged along the conveying direction of the conveying mechanism, the bottom buckling mechanism comprises a single bottom buckling component, a second bottom buckling component, a third bottom buckling component and a four folding tongue component in sequence, the single bottom buckling component comprises a single bottom buckling assembly and a positioning assembly for positioning the bottom tongue after the bottom buckling, the single bottom buckling assembly and the positioning assembly are linked by a first linkage assembly, and the second bottom buckling component and the third bottom buckling component are linked by a second linkage assembly.

[0006] By adopting the above technical solution, the paper box is transported under the action of the paper box storage conveying mechanism, and then the feeding mechanism grabs the paper box in the paper box storage conveying mechanism for feeding, and in the feeding process, the expansion mechanism is used to expand the paper box and then place it on the transmission mechanism for transmission. Under the action of the transmission mechanism, the paper box passes through the bottom buckle mechanism to complete the folding and locking of the paper box bottom tongue, passes through the pen-shaped feeding mechanism to realize the feeding of the pen-shaped product in the paper box, and passes through the closing mechanism to complete the closing of the paper box cover, thereby completing the automatic box loading operation.

[0007] When the paper box passes through the bottom buckle mechanism, the first bottom buckle component in the first bottom buckle member completes the bending operation of one of the bottom tongues of the paper box, and then the first linkage component drives the positioning component to position the bent bottom tongue to prevent it from rebounding. Then the three bottom buckle components move, and the second linkage component drives the second bottom buckle component to move to complete the bending operation of the remaining bottom tongues of the paper box and prevent them from rebounding. Then the bent paper box is transmitted to the four folding tongue components to complete the folding operation between the bottom tongues to form a folding lock. The linkage between the folding steps is realized by setting the first linkage component and the second linkage component, so as to reduce the number of driving sources used, reduce the production cost of the equipment, and make the equipment run more reliable.

[0008] It is further configured as follows: the bottom buckle assembly includes a mounting frame, a tongue plate slidably arranged on a mounting frame located at one side of the bottom of the paper box and reciprocating toward the paper box, a driving source, and a linkage structure that links the driving source and the tongue plate.

[0009] By adopting the above technical solution, a driving source drives a tongue plate to move toward one side of the paper box through a linkage structure, thereby pushing the bottom insert tongue of the paper box to bend toward the inside of the paper box, thereby completing the bottom buckling operation.

[0010] The invention is further configured as follows: it includes a guide slide groove which is arranged on a mounting frame and for sliding a tongue plate, the guide slide groove includes a guide buckle bottom section and a separation reset section in sequence along the movement direction of the tongue plate toward the paper box, the linkage structure includes a one-way linkage block which is hinged to a driving source and driven thereby, a positioning groove which positions the one-way linkage block in a linkage state and limits the rotation of the one-way linkage block on the side opposite to the paper box, a retaining torsion spring which drives the one-way linkage block to resist the positioning groove and maintain it in a linkage state, and a linkage reset spring which drives a tongue plate to move opposite to the paper box, when the tongue plate is located at the guide buckle bottom section, the one-way linkage block resists the tongue plate to form a linkage for driving the tongue plate to move toward the paper box, and when the tongue plate is located at the separation reset section, the one-way linkage block is separated from the tongue plate.

[0011] By adopting the above technical solution, the one-way linkage block is kept in a linkage state under the action of the torsion spring and cooperates with the positioning groove so that the one-way linkage block cannot rotate away from the paper box but can rotate toward one side of the paper box. A driving source drives the one-way linkage block to move toward the paper box against a tongue plate and passes through the guide buckle bottom section and the separation and reset section in sequence. When passing through the guide buckle bottom section, the bending operation of the bottom plug tongue is completed. When passing through the separation and reset section, the one-way linkage block is separated from a tongue plate, so that the tongue plate moves away from the paper box under the action of the reset spring to achieve reset. When a driving source drives the one-way linkage block away from the paper box, the one-way linkage block can pass over a tongue plate and then push a tongue plate toward the paper box again.

[0012] The further configuration is as follows: the positioning assembly includes a positioning mounting frame and a positioning tongue plate which is lifted and slidably arranged on the positioning mounting frame and is located directly below the paper box; the first linkage assembly includes a first linkage block which is slidably arranged on a mounting frame and is located between the guide slide groove and the paper box and corresponds to a driving path of a driving source; a first return spring which drives the first linkage block to move along a driving path of a driving source opposite to the paper box; and a first linkage groove formed on the first linkage block; the positioning tongue plate extends into the first linkage groove to drive the positioning tongue plate to reciprocate toward the bottom of the paper box.

[0013] By adopting the above technical solution, when a driving source drives the one-way linkage block to move from the bottom section of the guide buckle to a position close to the separation and reset section, a tongue plate completes the bending operation of the bottom plug tongue; when the one-way linkage block moves from the separation and reset section toward the first linkage block, a tongue plate returns a tongue plate to its original position when passing through the separation and reset section, and then drives the first linkage block to drive the positioning tongue plate to move toward the bottom of the paper box through the first linkage groove and position the bottom plug tongue to keep it in a bent state before it rebounds, thereby completing the linkage between the two steps to realize the positioning function of the bottom plug tongue.

[0014] The further configuration is as follows: the two-step buckle bottom component comprises two symmetrical and spaced-apart two-step buckle bottom components, the two-step buckle bottom component comprises two sliding sleeves and two tongue plates which are lifted and slidably arranged on the two sliding sleeves and located below the paper box, the movement paths of the two two tongue plates intersect with the two symmetrical bottom plugging tongues of the paper box respectively, the three-step buckle bottom component comprises three mounting frames, three tongue plates which are lifted and slidably arranged on the three mounting frames and located below the paper box, and three driving sources which drive the three tongue plates to move, the second linkage component structure comprises, along the movement direction toward the paper box, two linkage sections which are linked with the two-step buckle bottom component and used to drive the two tongue plates to drive the bottom plugging tongue to fold, a connecting section which connects the linkage between the two-step buckle bottom component and the three-step buckle bottom component, and three resetting sections which realize the resetting of the two tongue plates, when the second linkage component is in the connecting section, the two tongue plates first drive the bottom plugging tongue to fold and then drive the bottom plugging tongue to fold under the bottom plugging tongue driven by the two tongue plates through the three tongue plates.

[0015] By adopting the above technical solution, the three driving sources drive the three tongue plates to move toward the bottom of the paper box and, under the action of the second linkage component, first enter the second linkage section to drive the two tongue plates to move toward the bottom plugging tongue to complete the bending operation, then enter the connection section to drive the three tongue plates to move toward the bottom plugging tongue to complete the bending operation and fold the bottom plugging tongue under the bottom plugging tongue bent by the two tongue plates, then enter the three resetting sections to achieve the resetting of the two tongue plates, thereby avoiding the existing two tongue plates from interfering with the normal transmission of the box body, and the three tongue plates are offset against the bottom of the bottom plugging tongue to avoid its rebound and will not interfere with the normal transmission of the box body.

[0016] It is further configured as follows: the second linkage component includes a second linkage rod slidably set on the second tongue plate along the movement path of the second tongue plate, a connecting spring connecting the second linkage rod and the second tongue plate, a magnetic block fixedly set on the second linkage rod, and an iron piece fixedly set on the third tongue plate and located above the movement path of the magnetic block and adsorbed thereon, and the second sliding sleeve limits the second tongue plate from separating therefrom.

[0017] By adopting the above technical solution, when it is in the second linkage section, the connection spring is not stretched and the iron piece is adsorbed with the magnetic block, so that the three tongue plates can drive the two tongue plates to move upward through the connection spring. When the two tongue plates bend the bottom plug tongue, they are limited by the two sliding sleeves so that they cannot continue to move upward. Then, the two linkage sections enter the connection section, and the three tongue plates continue to move toward the bottom of the paper box to bend the other bottom plug tongue and stretch the connection spring during the movement. When entering the three reset sections from the connection section, the three tongue plates continue to move toward the bottom of the box body. At this time, the stretching elastic force of the stretched connection spring is greater than the magnetic force of the magnetic block, and the magnetic block is separated from the iron piece, so that the two tongue plates are reset, and the bottom plug tongue bent by the two tongue plates is limited by the bottom plug tongue bent by the three tongue plates and cannot rebound, and the three tongue plates always abut the bottom plug tongue to limit it, so as to complete the linkage between the two steps to realize the positioning function of the bottom plug tongue.

[0018] It is further configured that: the four-flange components include four-flange plates arranged directly below the paper box movement path and four driving sources for driving the four-flange plates to rise and fall.

[0019] By adopting the above technical solution, four driving sources drive four folding tongue plates to move so as to complete the folding operation of the folded bottom tongues, so that the bottom tongues are locked.

[0020] It is further configured as follows: the feeding mechanism includes a feeding rack, a first feeding rotary cylinder rotatably arranged on the feeding rack, a feeding motor driving the first feeding rotary cylinder to rotate, a second feeding rotary cylinder driven by the first feeding rotary cylinder, and a suction cup rack driven by the second feeding rotary cylinder.

[0021] By adopting the above technical solution, the suction cup frame is used to realize the grabbing of the paper box, and the grabbing movement of the paper box is realized by the coordinated arrangement of the first feeding rotary cylinder, the feeding motor and the second feeding rotary cylinder.

[0022] It is further configured as follows: the transmission mechanism includes a transmission frame, a transmission chain rotatably arranged on the transmission frame, a transmission motor driving the transmission chain to rotate, and a transmission frame slidably arranged on the transmission frame and connected to the transmission chain and for placing the paper box.

[0023] By adopting the above technical solution, the transmission motor drives the transmission chain to rotate, and the transmission chain then drives the transmission frame to move on the transmission rack.

[0024] It is further configured as follows: the covering mechanism includes a first covering frame, a first horizontal cylinder arranged on the first covering frame, a second lifting cylinder driven by the first horizontal cylinder, a third horizontal cylinder driven by the second lifting cylinder, and a flip tongue plate driven by the third horizontal cylinder; the covering mechanism also includes a second covering frame, a fourth horizontal cylinder arranged on the second covering frame, a fifth lifting cylinder and a sixth lifting cylinder driven by the fourth horizontal cylinder, and a seventh horizontal cylinder arranged on the second covering frame; the seventh horizontal cylinder is connected to a limiting plate, the sixth lifting cylinder is connected to a cover tongue plug plate, and the fifth lifting cylinder is connected to a cover pressing plate.

[0025] By adopting the above technical scheme, the seventh horizontal cylinder first drives the limit plate to move above the paper box opening, and then the first horizontal cylinder, the second lifting cylinder, the third horizontal cylinder and the flip tongue plate cooperate to drive the paper box cover to flip over and be located above the limit plate, and then the cover tongue is driven by the cover tongue plug plate to insert the paper feed box first, and then the limit plate is moved out and the matching pressing cover plate is used to press the cover plate against the paper box opening, so as to complete the closing operation of the paper box.

[0026] In summary, the present invention has the following beneficial effects: the production cost of the present invention is low and the equipment operation is more reliable. BRIEF DESCRIPTION OF THE DRAWINGS
