[0028] like Figure 1 As shown, this dual-station cardboard box forming machine includes a frame, a cardboard feeding device 2, and a face paper feeding device 1. A transverse cardboard conveyor 3 is installed on the frame. The face paper feeding device 1 conveys the face paper 11 onto the transverse cardboard conveyor 3 and sprays glue on it. The transverse cardboard conveyor 3 conveys the face paper 11 forward. Then, the cardboard feeding device 2 conveys the cardboard 10 above the face paper 11 and places the cardboard 10 onto the face paper 11, forming a shape as shown. Figure 7 The cardboard shown is then conveyed forward by the transverse cardboard conveyor 3.

[0029] After the paper 11 is pasted to the paperboard 10, the paperboard 10 needs to be edge wrapped (the front end of the paper 11 is folded over and pasted to the paperboard 10), and the application is provided with a paperboard edge wrapping device 5 in front of the transverse paperboard conveying device 3. As shown in Figure 2 , the paperboard edge wrapping device 5 comprises a support 54, a traction mechanism 51, an edge hooking mechanism 52 and an edge pressing mechanism 53, and the edge hooking mechanism 52 is located between the traction mechanism 51 and the edge pressing mechanism 53. The traction mechanism 51 comprises an upper and lower traction roller set (consisting of two traction rollers), which can convey the paperboard 10 forward; the edge pressing mechanism 53 comprises an upper and lower edge pressing roller set (consisting of two edge pressing rollers). Figure 3 Figure 4 As shown in , the edge hooking mechanism 52 comprises a rotating shaft 520 and an edge hooking piece 521, and the edge hooking piece 521 has a connecting part 522 and a hooking part 523. The connecting part 522 of the edge hooking piece 521 is connected to the rotating shaft 520, and the rotating shaft 520 is rotatably installed on the support 54.

[0030] Figure 5 As shown in , the working principle of the paperboard edge wrapping device 5 is as follows: first, the traction mechanism 51 pulls the paperboard 10 forward, and at the same time, the edge wrapping part of the front end of the paper 11 acts on the edge hooking piece 521 of the edge hooking mechanism 52. The hooking part 523 of the edge hooking piece 521 causes the front end of the paper 11 to roll up, and as the paperboard 10 continues to advance, the edge hooking piece 521 rotates clockwise with the rotating shaft 520 under the action of the paperboard 10. In this way, the hooking part 523 of the edge hooking piece 521 presses the paper 11 onto the paperboard 10 under the action of gravity, and as the paperboard 10 continues to advance, the edge pressing mechanism 53 further presses the paper 11 onto the paperboard 10, while the air bubbles between the paper 11 and the paperboard 10 are squeezed out (the paper 11 and the paperboard 10 are pasted together by glue, and air bubbles exist during pasting), thereby improving the adhesion and appearance of the paper 11 and the paperboard 10. When a paperboard 10 passes, the edge hooking piece 521 will rotate with the rotating shaft 520 due to gravity, thereby returning the edge hooking piece 521 to its original position, waiting for the arrival of the next paperboard 10. It should be noted that the edge wrapping here is only for the front end of the paperboard, and the edge wrapping of the rear end of the paperboard is completed at the paper box forming station. Of course, some paperboards only need to complete one end edge wrapping.

[0031] Figure 4 As shown in Figure 4 ​As shown, the present application is provided with a clamping groove 525 on the connecting part 522 of the hooking part 521, and a clamping part 526 above the hooking part 521, which is in transmission connection with the clamping part power source driving the clamping part 526 to move downward. Through the driving of the clamping part power source, the clamping part 526 can enter the clamping groove 525 of the hooking part 521. Figure 4 As shown, when the hooking part 521 rotates clockwise under the action of the paperboard 10 and stops, the clamping part power source drives the clamping part 526 to move downward, so that the clamping part 526 enters the clamping groove 525 of the hooking part 521, fixing the hooking part 521, so that the hooking part 521 maintains a certain gap with the paperboard 10 below and does not act on the paperboard 10; when a paperboard passes, the clamping part power source drives the clamping part 526 to move upward, and the hooking part 521 rotates counterclockwise due to gravity, returning to the initial state.

[0032] In order to drive the clamping part 526 to act, the clamping part 526 of the present application is connected with one end of the swing part 527, the middle part of the swing part 527 is hinged on the support 54, and the other end of the swing part 527 is in transmission connection with the clamping part power source. Through the driving of the clamping part power source, the swing part 527 rotates around the hinged point in the middle, so that the clamping part 526 can move up and down.

[0033] As shown, in order to make the hooking part 521 of the hooking part 523 tilt forward (as shown in the state of Figure 4 As shown, in order to make the hooking part 521 of the hooking part 523 tilt forward (as shown in the state of Figure 4 As shown, in order to make the hooking part 521 of the hooking part 523 tilt forward (as shown in the state of Figure 4 , the paper 11 can walk upwards along the hooking part 523. Of course, this requires the configuration of the part 524 under the condition that the hooking part 523 of the hooking part 521 adopts a common form (such as the V-shaped as shown in Figure 6 As shown, in order to make the hooking part 521 of the hooking part 523 tilt forward (as shown in the state of

[0034] In order to make the shaft 520 rotate quickly and speed up the returning speed of the hooking part 521, the present application is further provided with a counterweight 528 connected to the shaft 520, which makes the hooking part 523 of the hooking part 521 have a downward rotating trend. Through the counterweight 528, the hooking part 523 of the hooking part 521 can quickly return, and at the same time, the hooking part 523 of the hooking part 521 can tilt forward.

[0035] After the paperboard is finished with the bubble pressing and edge wrapping work, the paper box forming work can be carried out. In order to realize double-station forming, a longitudinal paperboard conveying device 7 is arranged in front of the paperboard edge wrapping device 5, the discharge direction of the paperboard edge wrapping device 5 intersects the conveying direction of the longitudinal paperboard conveying device 7, the paperboard is conveyed to the longitudinal paperboard conveying device 7 through the paperboard edge wrapping device 5, the longitudinal paperboard conveying device 7 has left and right discharge ends, and each discharge end is provided with a paper box forming device 9 on one side, so that there are two paper box forming stations, and a paperboard transfer mechanical hand 8 is arranged between the paper box forming device 9 and the longitudinal paperboard conveying device 7, the paperboard transfer mechanical hand 8 can transfer the paperboard on the longitudinal paperboard conveying device 7 to the paper box forming device 9, and the paperboard is formed into a paper box by the paper box forming device 9. The paper box forming device 9 comprises a paper box forming die, and the paperboard transfer mechanical hand 8 comprises a suction nozzle for sucking the paperboard, both of which are prior art and will not be described here.

[0036] The working principle is as follows: after a piece of paperboard falls on the longitudinal paperboard conveying device 7, the longitudinal paperboard conveying device 7 conveys to the left side, conveying the paperboard to the left discharge end, and the paperboard is sucked away by the paperboard transfer mechanical hand 8 at the left end; at this time, another piece of paperboard falls on the longitudinal paperboard conveying device 7, and the longitudinal paperboard conveying device 7 conveys to the right side, conveying the paperboard to the right discharge end, and the paperboard is sucked away by the paperboard transfer mechanical hand 8 at the right end, and the longitudinal paperboard conveying device 7 thus conveys left and right to send the paperboard to the two paper box forming stations, and the two paper box forming stations simultaneously perform the forming work, and the efficiency is significantly improved.

[0037] The paperboard bubble pressing mechanism only presses the bubble once, which may not be able to completely extrude the bubbles, in order to completely extrude the bubbles in the paperboard, the pre-bubble pressing mechanism 4 is further arranged above the transverse paperboard conveying device 3, the pre-bubble pressing mechanism 4 comprises a pre-bubble pressing plate and a pre-bubble pressing power source for driving the pre-bubble pressing plate to move up and down. Through the driving of the pre-bubble pressing power source, the pre-bubble pressing plate is pressed on the paperboard to press the bubble for the first time, and then the paperboard enters the paperboard bubble pressing mechanism to press the bubble for the second time, through the two times of bubble pressing, the bubbles in the paperboard can be basically extruded, the adhesion between the surface paper and the paperboard is more firm, and the finished product is more beautiful without bubbles.

[0038] After the paperboard 10 comes out of the paperboard edge wrapping device 5, it will deviate outward due to the inertia of forward movement, in order to accurately return the paperboard to the longitudinal paperboard conveying device 7, the paper blocking mechanism 6 is arranged outside the longitudinal paperboard conveying device 7, like Figure 8As shown, the paper blocking mechanism 6 includes a paper blocking plate 63 facing the discharging direction of the paperboard edge covering device 5 and a paper blocking power source 64 driving the paper blocking plate 63 to move to the inside. When the paperboard 10 comes out of the paperboard edge covering device 5 and hits the paper blocking plate 63 and falls on the longitudinal paperboard conveying device 7, then the paper blocking power source 64 drives the paper blocking plate 63 to move forward, and the paper blocking plate 63 pushes the paperboard 10 to the middle position of the longitudinal paperboard conveying device 7, so that the position of the paperboard 10 on the longitudinal paperboard conveying device 7 is corrected.

[0039] The size of the paperboard is different, in order to adapt to paperboards of different sizes, the paper blocking plate 63 is connected to the sliding seat 61, the sliding seat 61 is slidably arranged on the adjusting seat 60, the paper blocking power source 64 is installed on the adjusting seat 60, and the adjusting seat 60 is movably adjusted and installed on the rack. When the size of the paperboard changes, the adjusting seat 60 can be adjusted, so that the front and back positions of the paper blocking plate 63 change, so as to meet the paper blocking of paperboards of different sizes.

[0040] The paper box forming die of the application can adopt a common die, in order to realize the forming of paper boxes of different sizes, the application provides a paper box forming die with adjustable size.

[0041] As Figure 8 shown, the paper box forming die includes a die core A1, an upper left side die A2 and an upper right side die A3 are arranged above the die core A1, the upper left side die A2 is connected with a lower left side die A4, and the upper right side die A3 is connected with a lower right side die A5. The four side dies form the framework of the die, and the size of the die can be changed by moving and adjusting the four side dies.

[0042] The paper box forming die A of the application can realize transverse width adjustment (X-axis direction) and longitudinal height adjustment (Y-axis direction). The structure and adjustment principle will be introduced one by one.

[0043] As Figure 9 shown, the paper box forming die includes a die core A1, an upper left side die A2 and an upper right side die A3 are arranged above the die core A1, the upper left side die A2 is connected with a lower left side die A4, and the upper right side die A3 is connected with a lower right side die A5. The four side dies form the framework of the die, and the size of the die can be changed by moving and adjusting the four side dies. Figure 10As shown, the upper left mold A2 has two left guide bars A20, one at the front and one at the back. Each left guide bar A20 has a left elongated hole, and a left bolt A21 is installed inside the left elongated hole. The left bolt A21 is threaded onto the mold core A1. Similarly, the upper right mold A3 has two right guide bars A30, one at the front and one at the back. Each right guide bar A30 has a right elongated hole, and a right bolt A31 is installed inside the right elongated hole. The right bolt A31 is threaded onto the mold core A1. The upper left mold A2 has a left guide surface A22 with a left inclined edge A220. Similarly, the upper right mold A3 has a right guide surface A32 with a right inclined edge A320. The left guide surface A22 and the right guide surface A32 are staggered vertically. Additionally, on the mold core A... 1. A sliding block A6 is provided on the mold core A1. A rotatable lateral adjustment screw A7 is installed on the mold core A1. The lateral adjustment screw A7 is threadedly connected to the sliding block A6. A left guide wheel A61 and a right guide wheel A60 are installed on the sliding block A6. The left guide wheel A61 can act on the left inclined side A220 of the left guide surface A22, while the right guide wheel A60 can act on the right inclined side A320 of the right guide surface A32. In addition, a spring A70 is connected between the upper left mold A2 and the upper right mold A3, or a spring is connected between the upper left mold A2 and the mold core A1 and the upper right mold A3 and the mold core A1 (both of these methods can bring the upper left mold A2 and the upper right mold A3 closer together).

[0044] Its width adjustment principle is as follows: When it is necessary to increase the width of the mold (X-axis), such as... Figure 9 As shown, rotate the horizontal adjusting screw A7, as... Figure 12As shown, the transverse adjusting screw A7 drives the sliding seat A6 to move forward on the mold core A1. Since the left guide wheel A61 and the right guide wheel A60 are installed on the sliding seat A6, the left guide wheel A61 acts on the left inclined edge A220 of the left upper mold A2, and the right guide wheel A60 acts on the right inclined edge A320 of the right upper mold A3. Thus, the left upper mold A2 moves to the left (the two left guide strips A20 of the left upper mold A2 serve as guides to enable the left upper mold A2 to translate), and the right upper mold A3 moves to the right (the two right guide strips A30 of the right upper mold A3 serve as guides to enable the right upper mold A3 to translate). Since the left upper mold A2 is connected with the left lower mold A4, and the right upper mold A3 is connected with the right lower mold A5, the left upper mold A2 and the left lower mold A4 move to the left together, and the right upper mold A3 and the right lower mold A5 move to the right together. Thus, the width of the mold is widened. After the width is adjusted to the appropriate size, the left bolt A21 is tightened to fix the left upper mold A2 with the mold core A1, and the right bolt A31 is tightened to fix the right upper mold A3 with the mold core A1. Thus, the width of the mold is fixed. When the width of the mold is to be adjusted (X-axis), the left bolt A21 and the right bolt A31 are loosened, the transverse adjusting screw A7 is reversed, and the sliding seat A6 carrying the left guide wheel A61 and the right guide wheel A60 moves back. Under the action of the spring A70, the left upper mold A2 and the right upper mold A3 gradually move inward. Since the left guide surface A22 and the right guide surface A32 are staggered vertically, the left upper mold A2 and the right upper mold A3 can approach each other without interference, and can approach each other to the maximum extent, that is, the width of the mold can be reduced to the maximum extent. After the width is adjusted to the appropriate size, the left bolt A21 and the right bolt A31 are tightened again. Thus, the width of the mold is fixed.

[0045] In order to realize the height adjustment of the mold (Y-axis direction), the left guide shaft A24 is arranged between the left upper mold A2 and the left lower mold A4, and the left upper mold A2 or the left lower mold A4 can move up and down along the left guide shaft A24 (specifically, the left guide sleeve A40 is arranged on the left lower mold A4, the left guide shaft A24 is connected to the left upper mold A4, and the left guide shaft A24 can be extended and retracted in the left guide sleeve A40 to move up and down. Of course, the left guide sleeve A40 can be in an integral structure with the left lower mold A4, or the left guide shaft A24 can be directly extended and retracted in the hole of the left lower mold A4 to move up and down). The right guide shaft is arranged between the right upper mold A3 and the right lower mold A5, and the right upper mold or the right lower mold can move up and down along the right guide shaft (specifically, the right guide sleeve is arranged on the right lower mold, the right guide shaft is connected to the right upper mold, and the right guide shaft can be extended and retracted in the right guide sleeve to move up and down. Of course, the right guide sleeve can be in an integral structure with the right lower mold, or the right guide shaft can be directly extended and retracted in the hole of the right lower mold to move up and down). In addition, as shown in the figure, Figure 12As shown, a guide base A8 is arranged between the left lower side mold A4 and the right lower side mold A5, the guide base A8 is arranged on the left lower side mold A4 or / and the right lower side mold A5 in an axially movable manner through a side shaft A81 (that is, the guide base A8 is connected to the left lower side mold A4 or / and the right lower side mold A5, and the left lower side mold A4 and the right lower side mold A5 move in the transverse direction without affecting the position of the guide base A8), the guide base A8 has an upwardly inclined guide surface A80, a lifting adjusting block A9 is arranged on the guide surface A80 in a sliding manner, and the lifting adjusting block A9 is located at the bottom of the mold core A1, the left upper side mold A2 and the left lower side mold A4 are connected through the cooperation of the connecting shaft A25 and the fixed ring A41 (specifically, the fixed ring A41 is connected on the left lower side mold A4, the connecting shaft A25 is connected on the left upper side mold A2, the connecting shaft A25 is located in the fixed ring A41, the fixed ring A41 is loosened, and the connecting shaft A25 can move axially, the fixed ring A41 is tightened, and the connecting shaft A25 is fixed, of course, the connecting shaft A25 and the fixed ring A41 can be installed reversely).

[0046] The height adjustment principle is as follows: when the height of the mold needs to be increased (Y axis), for example, Figure 13 And Figure 13 As shown, the lifting adjusting block A9 is moved, and the lifting adjusting block A9 is lifted along the guide surface A80 of the guide base A8, so that the lifting adjusting block A9 lifts the mold core A1 up and down, since the left upper side mold A2 and the right upper side mold A3 are connected to the mold core A1, the left upper side mold A2 and the right upper side mold A3 are lifted, and when the height is adjusted to the appropriate height, the fixed ring A41 is tightened to fix the connecting shaft A25, so that the height of the mold is fixed.

[0047] The movement of the lifting adjusting block A9 on the guide surface A80 of the guide base A8 can be driven manually, or a bolt can be installed on the mold core A1, the bolt is threadedly connected with the lifting adjusting block, and the lifting adjusting block A9 is moved by rotating the bolt. These methods can be achieved. The present application provides a more reasonable structure: the guide base A8 has two front and rear guide surfaces A80, each guide surface A80 is arranged with a lifting adjusting block A9 in a sliding manner, and the two lifting adjusting blocks A9 are threadedly connected with the first longitudinal adjusting screw A10 and can move relatively. Through this structure, as long as the first longitudinal adjusting screw A10 is rotated, the two lifting adjusting blocks A9 can move relatively, so that the left upper side mold A2 and the right upper side mold A3 are lifted, and since the two lifting adjusting blocks A9 move together to lift, the rotation of the first longitudinal adjusting screw A10 will be more labor-saving, and the lifting will be more stable.

[0048] Since the lifting adjusting block A9 is not directly connected with the mold core A1, when the lifting adjusting block A9 moves downward, the upper left mold A2 and the upper right mold A3 can move downward through the gravity of the mold core A1 and the upper part thereof. However, due to the existence of the guiding friction and the guiding balance problem, the falling is not very stable. In order to make the upper left mold A2 and the upper right mold A3 move downward stably, the second longitudinal adjusting screw A11 which can rotate is installed on the guiding base A8, and the second longitudinal adjusting screw A11 is in threaded connection with the mold core A1. By rotating the second longitudinal adjusting screw A11, the mold core A1 can realize stable downward movement.

[0049] Finally, it is worth mentioning that the lifting adjusting block A9 of the present application has a chute (as shown by the dotted line position), and the guiding surface A80 of the guiding base A8 is located in the chute of the lifting adjusting block A9. The chute of the lifting adjusting block A9 can prevent the guiding base A8 from moving left and right, so that the lifting of the lifting adjusting block A9 is more stable. ​ Finally, it is worth mentioning that the lifting adjusting block A9 of the present application has a chute (as shown by the dotted line position), and the guiding surface A80 of the guiding base A8 is located in the chute of the lifting adjusting block A9. The chute of the lifting adjusting block A9 can prevent the guiding base A8 from moving left and right, so that the lifting of the lifting adjusting block A9 is more stable.
