The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] As Figures 1 to 10 shown, a drawer box type packaging box forming machine is characterized in that it includes a workbench 1, a top box support plate 2 is provided on the upper side of the workbench 1, a folding structure 3 for folding the sides of the drawer box is provided outside the top box support plate 2, a machine head 4 is also provided on the upper side of the workbench 1, the machine head 4 includes a pressure rod 40 and an upper die 41 adapted to the inner shape of the drawer box, the pressure rod 40 is used to press the bottom of the drawer box to be formed tightly, and after the sides of the drawer box are folded, the upper die 41 moves into the drawer box.

[0043] Under the action of the top box support plate 2 and the pressure rod 40, the packaging box to be formed is pressed tightly, and then the folding of each side is completed through the folding structure 3. Finally, under the action of the upper die 41, the face paper at the inner opening position of the package is turned over and pressed to the inner side of the packaging box and adhered to the inner wall of the packaging box embryo, thereby completing the forming of the drawer box type packaging box. The whole process is fully automated, thus improving production efficiency and reducing production costs.

[0044] At this time, there is a moving distance between the machine head 4 and the top box support plate 2. Therefore, it is necessary to fix the machine head 4 at the upper side position of the workbench 1. In this embodiment, as Figures 1 to 4 shown, the machine head 4 is fixed at the upper side of the workbench 1 through a gantry 5. The machine head 4 further includes a machine head fixing plate 42. A vertical main arm 43 is provided on the side of the machine head fixing plate 42 through a guide rail slider. A rack 44 is provided on the side of the vertical main arm 43. The machine head fixing plate 42 is provided with a motor 45. A driving gear meshing with the rack 44 is provided on the shaft of the motor 45. The upper die 41 is fixed at the lower side position of the vertical main arm 43. The vertical main arm 43 is connected to the machine head fixing plate 42 through a guide rail slider. Under the action of the motor 45, the up and down movement of the vertical main arm 43 can be controlled through gear connection. At this time, the upper die 41 is fixed at the lower side position of the vertical main arm 43. In this way, under the action of the motor 45, the upper die 41 moves up and down, thereby completing the pressing of the paper edge turning on the inner side of the packaging box. At this time, the upper die 41 is fixed at the lower side position of the vertical main arm 43 through fasteners, so that the upper die 41 can be replaced according to different models / sizes of packaging boxes, so that the molding machine can adapt to different models / sizes of packaging boxes.

[0045] In addition to the need for the upper die 41 to move up and down, the pressing rod 40 also needs to move up and down, and the pressing rod 40 should be arranged at the inner side position of the upper die 41. Therefore, in this embodiment, as Figures 2 to 4 shown, a pressing cylinder 46 is fixed on the outer side of the vertical main arm 43. The pressing rod 40 is fixedly connected to the piston rod of the pressing cylinder 46. The pressing rod 40 is of a linear guide structure. The vertical main arm 43 is provided with a slider adapted to the linear guide structure of the pressing rod 40. The pressing rod 40 moves up and down under the action of the pressing cylinder 46. A through hole communicating up and down is provided in the middle of the upper die 41. The pressing rod 40 moves up and down in the through hole of the upper die 41. At this time, under the action of the pressing cylinder 46, the pressing rod 40 moves up and down, and a through hole communicating up and down through which the pressing rod 40 passes is provided in the middle of the upper die 41 (that is, a vertical through hole is provided at the top position of the upper die 41, and the pressing rod 40 passes through and moves up and down at this through hole position). In this way, the pressing rod 40 can move up and down in the through hole inside the upper die 41, thereby realizing the pressing of the packaging box. At this time, the pressing rod 40 is located at the inner side position of the upper die 41. During the folding process of the packaging box, the pressing rod 40 first presses the packaging box, and then the upper die 41 moves up and down to fit the turned edge of the paper to the inner wall position of the packaging box.

[0046] Specifically, the pressing rod 40 adopts a linear guide structure at this time, and a fixed slider is provided on the vertical main arm 43, so that the pressing rod 40 can ensure linear movement during the up and down movement.

[0047] At this time, in order to ensure the compactness of the overall structure, the vertical main arm 43 is provided with a slot in the middle position and a hole at the bottom. The pressure rod 40 is located in the slot, and passes through the vertical main arm 43 at the bottom hole, so as to reduce the occupied position of the vertical main arm 43 and the pressure rod 40, and improve the space utilization rate.

[0048] During the process of forming the packaging box, the top box support plate 2 is used to place the packaging box. At this time, a lower template adapted to the shape of the packaging box can be fixed on the upper side of the top box support plate 2 to improve the support stability of the top box support plate 2 in the lower direction of the product. At the same time, since the packaging box needs to move up and down during the forming process, it is necessary to control the up and down movement of the top box support plate 2. Specifically, in this embodiment, as Figure 5 shown, an upper top cylinder 21 is provided on the lower side of the workbench 1. The piston rod of the upper top cylinder 21 is connected with a top rod 22. The top rod 22 is a linear guide structure. The top rod 22 passes through the workbench 1 and is fixed to the top box support plate 2. The upper top cylinder 21 is fixed at the lower side position of the workbench 1 through a bracket. Under the action of the upper top cylinder 21, the top rod 22 can move up and down, so as to control the up and down movement of the top box support plate 2. At this time, a fixed slider is provided on the lower side of the workbench. The slider cooperates with the linear guide structure of the top rod 22, so that the top rod 22 maintains a straight up and down movement during the movement.

[0049] The folding structure 3 is a structure for folding the sides of the packaging box and pressing the flanges of the face paper. At this time, since the front and rear sides of the packaging box are the same, and the left and right sides are the same, therefore, in this embodiment, as Figures 6 to 10 shown, the folding structure 3 includes left and right folding structures 313 located on the left and right sides of the top box support plate 2, and front and rear folding structures 323 located at the front and rear positions of the top box support plate 2. At this time, the left and right folding structures 313 are the same, and the front and rear folding structures 323 are the same, and are symmetrically distributed with the top box support plate 2 as the center.

[0050] The left - right folding structure 313 includes longitudinal guide rails located on the left and right sides of the top box support plate 2. The upper side of the longitudinal guide rails is connected with a longitudinal moving plate 311 through sliders. The upper side of the longitudinal moving plate 311 is provided with a vertical plate 312. The side of the vertical plate 312 is provided with a transverse folding cylinder 313. The piston rod of the transverse folding cylinder 313 is connected with a scraper 314. The upper side of the longitudinal moving plate 311 is also provided with a rotary cylinder 315. The rotating shaft of the rotary cylinder 315 is connected with a wool roller 316. The scraper 314 and the wool roller 316 face the middle top box support plate 2. The outside of the longitudinal guide rails is provided with a longitudinal driving mechanism for controlling the movement of the longitudinal moving plate 311 along the longitudinal guide rails. The longitudinal guide rails are arranged on the upper side of the workbench 1 through brackets. The longitudinal moving plate 311 is connected through sliders on the upper side of the longitudinal guide rails. The hanging plate moves horizontally under the action of the transverse folding cylinder 313, and the wool roller 316 rotates under the action of the rotary cylinder 315. At this time, there is also a left - right motor 45 for driving the longitudinal moving plate 311 to move on the longitudinal guide rails. There are two synchronous wheels on the side of the longitudinal guide rails, and a synchronous belt is arranged between the synchronous wheels. The longitudinal moving plate 311 is fixed to the synchronous belt. In this way, when the synchronous belt rotates, the longitudinal moving plate 311 can move, so as to control the longitudinal movement of the scraper 314 and the wool roller 316. At this time, the two synchronous wheels on the left and right sides are connected through a shaft, and at the same time, a left - right motor 45 is used to control the longitudinal movement of the longitudinal moving plates 311 on the left and right sides.

[0051] During the folding and forming process, first, the height position of the packaging box is controlled by the upper - top cylinder 21 and the pressing cylinder 46, so that the side of the packaging box is flush with the position of the scraper 314. After the front side panel is folded, the left and right side panels located on the sides of the front and rear side panels are in a vertical state. By controlling the transverse folding cylinder 313, the scraper 314 moves outwards, and then contacts the left and right side panels of the packaging box, and presses the left and right side panels to contact the front and rear side panels. After being fixed by the adhesive on the contact surface, the longitudinal moving plate 311 moves. Under the action of the rotating motor 45, the wool roller 316 is controlled to rotate to the outside of the left and right side panels. During the movement of the longitudinal moving plate 311, the wool roller 316 completes the brushing process, so as to attach the face paper on the side to the outside of the embryo box.

[0052] There are two front-back folding structures 323, which are symmetrically distributed on the front and back sides of the top box support plate 2 respectively. At this time, the front-back folding structure 323 includes a flap fixing plate 321. One end of the flap fixing plate 321 close to the top box support plate 2 is connected with a flipping drive shaft 322 through a bearing. The end of the flipping drive shaft 322 is connected with a flap small rod 323 and a flap rod 324. A mold plate 325 is fixed on the side of the flap rod 324. A rotating seat 326 is rotatably arranged on the side of the flap fixing plate 321 through a rotating pin shaft. A flap cylinder 327 is fixed on the rotating seat 326. The piston rod of the flap cylinder 327 is connected with a rod end joint shaft 328, and the rod end joint shaft 328 is rotatably connected with the flap small rod 323. When the piston rod of the flap cylinder 327 moves, the flap small rod 323, the flap rod 324 and the mold plate 325 rotate between the horizontal position and the vertical position. The flap fixing plate 321 is provided with a shaft hole, and the folding drive shaft is rotatably connected with the flap fixing plate 321 through a bearing at the shaft hole position. At this time, both ends of the folding drive shaft protrude from the side of the flap fixing plate 321. In this way, the protruding parts are respectively fixed with the flap small rod 323 and the flap rod 324. At the same time, a flap cylinder 327 for driving the flap rod 324 to rotate is also provided. At this time, the cylinder body of the flap cylinder 327 is rotatably arranged at the side position of the flap fixing plate 321, and the piston rod of the flap cylinder 327 is rotatably connected with the flap rod 324 through the rod end joint shaft 328. In this way, when the piston rod of the flap cylinder 327 extends or retracts, the flap rod 324 will rotate around the flipping drive shaft 322, thereby controlling the rotation of the flap small rod 323 at the other end. At this time, the flap rod 324 and the flap small rod 323 can rotate between the horizontal position and the vertical position, so as to fold the side of the blank box at the side positions of the flap rod 324 and the flap small rod 323.

[0053] After the folding of the embryo box is completed, it is also necessary to attach the edge of the facing paper at the flanging position. At this time, therefore, in this embodiment, the left and right folding structure 313 further includes a left and right facing paper fitting mechanism 33. The left and right facing paper fitting mechanism 33 includes left and right mounting plates 331. The side of the left and right mounting plates 331 is connected with a left and right blade fixing seat 332 through a guide rail slider structure. The upper side of the blade fixing seat is provided with a left and right blade adjusting seat 333. The side of the left and right blade adjusting seat 333 is provided with a first fixing groove 334. The left and right blades are fixed at the position of the first fixing groove 334. The upper side of the blade fixing seat is also provided with a first air cylinder 335 for controlling the horizontal movement of the left and right blade adjusting seats 333. The left and right facing paper fitting mechanism 33 further includes a vertical adjustment air cylinder 336 for controlling the up and down movement of the blade fixing seat. Under the action of the vertical adjustment air cylinder 336, the left and right blade fixing seats 332 move up and down, and then the left and right blades can move up and down, so that the edges of the facing paper at different heights on the upper and lower sides of the side position can be targeted. Under the action of the first air cylinder 335, the left and right blades move horizontally, so that the flanging position of the edge of the facing paper can be pressed to be inclined, so as to facilitate the subsequent fitting of the edge of the facing paper at the lower side position by the hair roller 316, and to facilitate the subsequent pressing of the edge of the facing paper at the opening position downward by the upper die 41 to be fitted with the inner wall of the embryo box.

[0054] Similarly, the front and rear folding structure 323 further includes a front and rear facing paper fitting mechanism 34. The front and rear facing paper fitting mechanism 34 includes a second air cylinder 341 fixed to the flap fixing plate 321. The piston rod of the second air cylinder 341 is connected with a front and rear blade adjusting seat 342. The front and rear blade adjusting seat 342 is provided with a second fixing groove 343. The front and rear blades are fixed at the position of the second fixing groove 343. At this time, only the second air cylinder 341 is needed to control the front and rear movement (longitudinal) of the front and rear blades, so as to press the flanging position of the edge of the facing paper at the corresponding side position to be inclined, and to facilitate the subsequent pressing of the edge of the facing paper at the opening position downward by the upper die 41 to be fitted with the inner wall of the embryo box.

[0055] In order to adapt to different models / sizes of packaging boxes, it is necessary to adjust the distance between the two front and rear folding structures 323 and the two left and right folding structures 313. Therefore, in this embodiment, the front and rear folding structure 323 further includes a longitudinal displacement structure 35. The longitudinal displacement structure 35 includes a longitudinal guide rail fixed on the upper side of the workbench 1. The upper side of the longitudinal guide rail is connected with a longitudinal template base 351 through a slider. The flap fixing plate 321 is fixed on the upper side of the longitudinal template base 351. At this time, the flap fixing plate 321 is arranged on the upper side of the longitudinal guide rail through the longitudinal template base 351. By changing the position of the longitudinal template base 351 on the longitudinal guide rail, the positions of the flap rod 324, the flap small rod 323, and the front and rear blades can be adjusted to adapt to different sizes of packaging boxes.

[0056] Similarly, the left-right folding structure 31 3 further includes a lateral displacement structure 36. The lateral displacement structure 36 includes a lateral guide rail fixed to the upper side of the workbench 1. The upper side of the lateral guide rail is connected with a lateral template base 361 through a slider. The longitudinal guide rail of the left-right folding structure 313 is fixed to the lateral template base 361 through a bracket. A lateral cylinder 362 is fixed to the side of the lateral template base 361. The left and right mounting plates 331 are connected to the piston rod of the lateral cylinder 362, so as to adjust the lateral movement of the left and right mounting plates 331. The cylinder block of the vertical adjustment cylinder 336 is fixed to the side of the lateral template base 361 to control the up and down movement of the blade fixing seat.

[0057] After the face paper is attached to the blank box, there may be air bubbles on the attachment surface. In order to discharge the air bubbles, in this embodiment, the molding machine further includes an exhaust structure. The exhaust structure includes left and right exhaust plates 61 fixed to the sides of the left and right mounting plates 331. The left and right exhaust plates 61 are located on one side close to the top box support plate 2.
