Description

Technical Field

[0001] This utility model relates to the field of folding box processing and forming technology, specifically to a feeding device and a folding box mounting machine. Background Technology

[0002] A finished folding box typically consists of a shell and two side wings. The shell structure usually consists of a main cardboard in the middle, main body panels at the front and rear ends of the main cardboard, and face paper pasted on the front and back of these main cardboard and main body panels. The side wings are usually made of five-ply or three-ply cardboard with face paper.

[0003] The manufacturing process of folding boxes can be roughly divided into the following parts:

[0004] (1) Sheet processing: Five rectangular cardboard sheets are pasted onto a face paper to connect them into a whole, forming the sheet part of the folding box cardboard; among them, the cardboard in the middle is the main cardboard, and the two cardboard sheets on both sides of the main cardboard are the main body sub-boards;

[0005] (2) Side wing processing: The multi-part cardboard is glued onto a sheet of face paper to form a whole, and then another sheet of face paper is wrapped on top of the multi-part cardboard to complete the packaging of the side wing cardboard;

[0006] (3) Assembly of the outer shell and side wings: The outer shell from step (1) and the side wings from step (2) are bonded together to form a whole, such as Figure 7 ;

[0007] (4) Folding box mounting: The assembled body after the outer shell and side wings are glued is stacked on a tray or material tray. The stacked assembly is then manually fed into the feeding device. The feeding device feeds the assembly and transfers it to the outer shell positioning device. The outer shell part transferred into the outer shell positioning device is completely flat. The cardboard is positioned in the positioning machine. Then, the robot grabs the positioned assembly and glues the side of the outer shell part of the assembly that is not covered with the face paper to the face paper conveyed on the conveyor belt to complete the mounting of the inner lining paper on the outer shell part of the folding box.

[0008] (5) Apply adhesive to the side wings and fold into a box.

[0009] In the aforementioned processing technology, because the side wings and the outer shell are bonded together in a staggered manner, the thickness of the main cardboard in the outer shell portion is increased. This results in a height difference between the main cardboard of the outer shell portion and the main body panels at both ends when the assembly is stacked, with the height difference becoming increasingly pronounced as the stacking height changes. The final result is that the main body panels are tilted relative to the main cardboard. This means that when picking up the folding box cardboard, the tilted main body panels may not be effectively grasped. Therefore, during the transfer of the folding box, the main body panels on both sides of the main cardboard collapse completely under gravity. Consequently, when the folding box cardboard is fed into the outer shell positioning device, the main body panels may be pressed under the main cardboard or directly bent, resulting in an uneven outer shell. This prevents the proper mounting of the inner lining paper on the outer shell of the folding box, leading to defective products. Summary of the Invention

[0010] To address the problems and shortcomings of the existing technology, this utility model proposes a feeding device suitable for a folding box mounting machine. The feeding device of this utility model can adjust the angle of the main body partition of the gripped folding box cardboard before transferring the folding box cardboard to the next process. During the transfer and feeding, the main body partition will not be pressed down or bent, thus improving the quality of the inner lining paper of the folding box cardboard, reducing the generation of defective and waste products, and saving production costs.

[0011] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:

[0012] On one hand, this utility model proposes a feeding device suitable for a folding box mounting machine, including a feeding component that can be driven to reciprocate between a feeding position and a discharging position. The feeding position is provided with a hopper for storing folding box cardboard, and the discharging position is provided with a receiving device. The feeding component includes a suction cup frame beam, a suction cup frame, and a lifting mechanism. The suction cup frame beam is slidably connected to both sides of the machine frame and can be driven to reciprocate between the feeding position and the discharging position. The suction cup frame is mounted on the suction cup frame beam through the lifting mechanism. The suction cup frame is provided with a first vacuum suction cup for adsorbing folding box cardboard and an adaptive adjustment mechanism that drives the main body of the folding box cardboard to rotate upward around one side crease.

[0013] Preferably, the second vacuum suction cup is mounted on the suction cup frame via a second vacuum suction cup mounting base. One end of the second vacuum suction cup mounting base is rotatably connected to the suction cup frame, and the other end is rotatably connected to a cylinder on the suction cup frame. The second vacuum suction cup rotates relative to the suction cup frame to adsorb the main body panel and drives the main body panel to rotate upward around one side crease.

[0014] Preferably, the hopper is provided with a paper feeding assembly, which includes a main lifting mechanism mounted on the hopper frame and a material platform mounted on the main lifting mechanism. The main lifting mechanism drives the material platform to reciprocate up and down.

[0015] Preferably, the main lifting mechanism includes a main lifting power source fixed on the hopper frame and a main transmission unit connected to the main lifting power source. The main transmission units are in two sets and are symmetrically arranged on the left and right sides of the material platform. Under the driving action of the main lifting power source, the main transmission units drive the material platform to move up and down reciprocally.

[0016] Preferably, the main drive unit includes a first sprocket and chain assembly fixed on the hopper frame. Each sprocket of the first sprocket and chain assembly has a main lifting sprocket on its rotating shaft. The main lifting sprocket has a main lifting chain on its main lifting chain, and one end of the main lifting chain is connected to the material platform.

[0017] Preferably, the silo is further provided with a secondary lifting mechanism and a material transfer mechanism. The secondary lifting mechanism includes a secondary lifting power source mounted on the silo frame and a secondary transmission unit connected to the secondary lifting power source. Two sets of the secondary transmission units are symmetrically arranged on the left and right sides of the material platform. The material transfer mechanism is connected to the secondary transmission units. The main transmission unit drives the material platform to rise. When the material platform and the material transfer mechanism are on the same horizontal line, the secondary lifting power source drives the secondary transmission units to move, driving the material transfer mechanism to rise and transferring the material on the material platform to the material transfer mechanism.

[0018] Preferably, the auxiliary transmission unit includes a second sprocket and chain assembly fixed on the hopper frame. Each sprocket of the second sprocket and chain assembly has an auxiliary lifting sprocket on its rotating shaft. An auxiliary lifting chain is provided on the auxiliary lifting sprocket, and one end of the auxiliary lifting chain is connected to the material transfer mechanism.

[0019] Preferably, the material transfer mechanism includes a fork and a fork support frame. The fork support frame is connected to the auxiliary transmission units on both sides. A tray is provided on the material platform, and the upper support surface of the tray has a strip-shaped groove that cooperates with the fork. The main transmission unit drives the material platform to rise. When the tray passes through the inside of the fork support frame and the strip-shaped groove is at the same horizontal line as the fork support frame, the fork is pushed into the strip-shaped groove and its two ends are supported on the fork support frame. The auxiliary lifting power source drives the auxiliary transmission unit to move, driving the fork support frame to rise.

[0020] Based on the same inventive concept, this utility model also proposes a folding box mounting machine, which includes the feeding device described above.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model adds an adaptive adjustment mechanism to the suction cup frame. After the first vacuum suction cup adsorbs the folded carton cardboard in the hopper, it can pull and adjust the main body partition plate, which is not on the same plane as the main cardboard at both ends of the folded carton, to be on the same plane as the main cardboard, or at least adjust it so that the angle between the extension line of the main body partition plate and the main cardboard does not exceed the included angle threshold range. In general, the feeding device of this utility model can adjust the tilt of the main body partition plate before transferring it to the next process. During feeding, the main body partition plate will not be pressed down or bent, and the feeding can be smooth. Therefore, the folded carton cardboard entering the shell positioning device is flat, which can meet the requirements of subsequent production and processing, and smoothly complete the mounting of the inner lining paper on the folded carton cardboard. The feeding device of this utility model can improve the quality of the inner lining paper mounting of the folded carton cardboard, reduce the generation of defective and waste products, and save production costs.

[0023] 2. The adaptive adjustment mechanism of this utility model is a vacuum suction cup that can rotate in a vertical plane. During rotation, the angle (inclination) of the suction surface of the vacuum suction cup is constantly changing. Based on the rotation of the vacuum suction cup, the suction surface of the second vacuum suction cup can be completely matched with the surface of the inclined main body plate. At this time, the second vacuum suction cup can firmly adhere to the main body plate of the shell. At the same time, the rotation and reset of the vacuum suction cup can drive the adsorbed main body plate to rotate upward along one side crease, adjusting until the angle between the main body plate and the extension line of the main cardboard meets the material feeding requirements, which can meet the processing requirements of the next process. Therefore, the adaptive adjustment mechanism of this utility model has the function of adjusting the inclined main body plate to a preset angle, and also has the function of adsorbing and gripping material, which not only ensures the production quality of the folding box, but also simplifies the complexity of the overall structure.

[0024] 3. With the cooperation of the material transfer mechanism, the paper feeding assembly of this utility model can achieve the effect of feeding without stopping the machine, which significantly improves the production efficiency of the equipment. Attached Figure Description

[0039] To enable those skilled in the art to better understand the technical solutions of this utility model, the following will further illustrate the technical solutions for achieving the purpose of this utility model through several specific embodiments. It should be noted that the technical solutions claimed by this utility model include, but are not limited to, the following embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this utility model.

[0040] Example 1

[0041] First, such as Figure 8As shown, when the folded box cardboard to be lined with inner lining paper is stacked, the main cardboard 100 in the middle is thicker, resulting in a height difference between the main cardboard 100 and the main body panels 200 at both ends. This height difference becomes more pronounced as the stacking height changes. The main body panels 200 on both sides are tilted relative to the main cardboard 100, and the two are not on the same horizontal plane. Figure 9 As shown in the figure (θ and β are the angles between the two main body panels 200 on one side and the extension line of the main cardboard), when the folding box cardboard is being picked up, the picking structure may not be able to effectively pick up the main body panels 200 with a large tilt. Therefore, after the folding box is picked up and lifted, the main body panels 200 on both sides collapse under the action of gravity. As a result, when the material is unloaded, the main body panels 200 may be pressed under the main cardboard 100, or the main body panels 200 may be directly bent during the unloading process. In the end, the inner lining paper cannot be laminated on the outer shell of the folding box cardboard, and the product produced is a defective product that cannot be used.

[0042] Based on this, in order to solve the above-mentioned technical problems, embodiments of this utility model propose a feeding device suitable for a folding box mounting machine. The structure of the feeding device is described in the appendix to the instruction manual. Figures 1-4 As shown, the feeding device includes a material-picking component 2 slidably mounted on the frame. The material-picking component 2 can be driven to move horizontally back and forth between the material-picking position and the material-discharging position. The material-picking position is provided with a hopper 1 for storing folded box cardboard, and the material-discharging position is provided with a receiving device 6 for transferring folded box cardboard. The material-picking component 2 includes a suction cup frame beam 21, a suction cup frame 22, and a lifting mechanism 23. The suction cup frame beam 21 is slidably connected to both sides of the frame. The suction cup frame 22 is mounted on the suction cup frame beam 21 through the lifting mechanism 23. The suction cup frame 22 is provided with a first vacuum suction cup 3 for adsorbing folded box cardboard and an adaptive adjustment mechanism 4 for driving the main body plate 200 of the folded box cardboard to rotate upward around one side crease.

[0043] The working process and principle of the feeding device in the embodiments described in this utility model are as follows: The folded cardboard boxes to be fed are stacked in the hopper, as shown in the schematic diagram of the stacking of the folded cardboard boxes. Figure 8As shown, the material picking assembly 2 first moves to the material picking position where the hopper is located. Then, the lifting mechanism 23 on the suction cup frame beam 21 is activated, driving the suction cup frame 22 to descend, which in turn drives the first vacuum suction cup 3 to descend. The first vacuum suction cup 3 picks up a folded cardboard sheet from the hopper. Then, the adaptive adjustment mechanism 4 on the suction cup frame acts on the main body partitions 200 on both sides of the main cardboard 100, driving the main body partitions 200 to rotate upward around one side crease, adjusting the tilt of the main body partitions 200 to a suitable angle (that is, adjusting the angle between the main body partitions 200 and the extension line of the main cardboard to a suitable angle for material placement). Then, the lifting mechanism 23 is activated, driving the suction cup frame 22 to move upward. Then, the suction cup frame beam 21 moves horizontally to the material placement position where the receiving device 6 is located. The lifting mechanism 23 then drives the suction cup frame 22 to descend. The material picking assembly 2 places the flattened folded cardboard sheet on the receiving device 6, which then transports it to the next process to paste the face paper on the other side of the folded cardboard sheet's outer shell.

[0044] In the embodiment described in this utility model, for the angle adjustment of the two main body panels 200, the adaptive adjustment mechanism 4 drives the main body panel 200 to rotate upward around one side crease, which can adjust the main body panel 200 to one of the following three states:

[0045] (1) Drive the main body panel 200 to rotate upward around one side crease until the main body panel 200 and the main paperboard 100 are in the same plane (e.g. Figure 10 (as shown)

[0046] (2) Drive the main body panel 200 to rotate upward around one side crease, and rotate the main body panel 200 to a position above the main cardboard 100 (e.g. Figure 11 As shown, the main body panel 200 is in an upward-curving state.

[0047] (3) Drive the main body panel 200 to rotate upward around one side crease, while the main body panel 200 remains below the main cardboard 100 (e.g. Figure 9 (As shown).

[0048] It should be noted that, in the first case, when the main body partition 200 is rotated upwards to be in the same plane as the main paperboard 100, the angle between the main body partition 200 and the extension line of the main paperboard is 0°.

[0049] In the second scenario, when the main plate 200 is driven to rotate upwards and is positioned above the main cardboard 100, the main plate 200 will not be pressed under the main cardboard 100 during material feeding. However, in order to ensure the flatness of the entire cardboard during material feeding, the angle between the main plate 200 and the extension line of the main cardboard is usually not too large (i.e., the upward tilt is small) after the main plate 200 rotates to the top. In this way, the upward tilting main plate can also be reset to be in the same plane as the main cardboard 100 under its own weight.

[0050] In the third case, after the adaptive adjustment mechanism 4 drives the main plate 200 to rotate upward, it is still located below the main cardboard 100. However, the angle between the main plate 200 and the extension line of the main cardboard is sufficient for feeding. The main plate 200 will not be pressed under the main cardboard 100 or bent. At this time, the angle between the two is generally between 0-45°.

[0051] In other words, this invention allows for the following adjustments: the main dividing plate 200 can be directly adjusted to be horizontal with the main cardboard 100; the main dividing plate 200 can be directly adjusted to be above the main cardboard 100; or the main dividing plate 200 can be below the main cardboard 100, but the angle between it and the extension line of the main cardboard does not exceed a preset angle threshold range. It is not necessary to adjust it to be horizontal with the main cardboard 100. As long as the requirements of the above three situations are met, the main dividing plate 200 will generally not be pressed under the main cardboard 100 or bent during material feeding. This ensures that the outer shell of the cardboard fed into the next process is flat, meeting the processing requirements.

[0052] Since the adaptive adjustment mechanism 4 has adjusted the tilt of the main body partitions 200 on both sides of the main cardboard 100 in advance, the main body partitions 200 of the folded box cardboard transferred to the receiving device 6 will not be pressed under the main cardboard 100 or bent. Finally, the outer shell of the folded box cardboard can be successfully laminated with the inner lining paper.

[0053] It is worth mentioning that the frame is typically equipped with a horizontal drive mechanism that drives the suction cup frame beam 21 to reciprocate horizontally between the hopper 1 and the receiving device 6. This horizontal drive mechanism usually consists of two sets of pulley assemblies symmetrically arranged on both sides of the frame. The two ends of the suction cup frame beam 23 are connected to the pulley assemblies on both sides of the frame, and the two pulley assemblies are generally connected to the horizontal drive power source via a synchronous transmission shaft to ensure the synchronicity of their movements. Driven by the synchronously moving pulley assemblies on both sides, the suction cup frame beam 21 reciprocates horizontally between the material picking position and the material discharging position.

[0054] It is understood that the horizontal drive power source is usually a servo motor, hydraulic motor or other components. This utility model does not limit the specific structural form of the horizontal drive power source, as long as it can drive the pulley assembly to move.

[0055] Furthermore, the horizontal drive mechanism can employ either a pulley assembly or a sprocket and chain assembly. Both pulley and sprocket / chain assemblies are common transmission components in the field and are well-known technologies, so they will not be described in detail here.

[0056] Furthermore, the lifting mechanism 23 is typically a lifting cylinder or an electric cylinder. The lifting mechanism 23 is fixed to the suction cup frame beam 21, and its movable end is connected to the suction cup frame 22, driving the suction cup frame 22 to move up and down reciprocally.

[0057] Furthermore, the lifting mechanism 23 can also be a slide rail slide table, which is fixed on the suction cup frame beam 21. The suction cup frame 22 is connected to the movable end of the slide rail slide table, and moves up and down reciprocally under the driving action of the slide rail slide table.

[0058] This utility model does not limit the specific structural form of the lifting mechanism 23, as long as it can drive the suction cup frame 22 to rise and fall. Furthermore, the lifting mechanism 23 is a known technology and will not be described in detail here.

[0059] Example 2

[0060] This embodiment discloses a feeding device suitable for a folding box mounting machine. Based on Embodiment 1, refer to the appendix of the instruction manual. Figures 3-5 As shown, the adaptive adjustment mechanism 4 includes a second vacuum suction cup 41 rotatably mounted on the suction cup holder 22. The second vacuum suction cup 41 can rotate in a vertical plane to adjust the angle of its suction cup adsorption surface.

[0061] During the material gripping process, the first vacuum suction cup 3 on the suction cup frame 22 first adheres to the main cardboard 100 in the middle of the folding box and the side wings 300 on both sides. At the same time, the second vacuum suction cup 41 rotates in the vertical plane towards the main body plate 100 (the angle of its adsorption surface changes continuously during the rotation) until the adsorption surface of the second vacuum suction cup 41 is completely attached to the surface of the main body plate 200. The second vacuum suction cup 41 adsorbs the main body plate 200. Then, the second vacuum suction cup 41 rotates in the opposite direction, causing the main body plate 200 to rotate upward around the corresponding fold. Finally, the tilted main body plate 200 is pulled and stretched by the second vacuum suction cup 41 until the outer shell of the entire folding box cardboard is roughly flattened. The second vacuum suction cup 41 then stops rotating. Then, the first vacuum suction cup 3 and the second vacuum suction cup 41 continue to adsorb the material. Driven by the lifting mechanism 23 and the suction cup frame beam 21, the gripped folding box cardboard is transported to the receiving device 6.

[0062] Therefore, in the embodiment described in this utility model, the adaptive adjustment mechanism 4 achieves both the effect of adjusting the tilt angle of the main body plate 200 and the effect of adsorbing and gripping the material, greatly simplifying the complexity of the structure. The second vacuum suction cup 41 rotates in the vertical plane, and can continuously adjust and change the angle of its suction surface, so that the angle of the suction surface matches the tilt angle of the main body plate 200. The suction surface of the suction cup can completely adhere to the surface of the main body plate 200 and firmly hold the main body plate 200. Then, the tilt degree of the main body plate 200 is adjusted again. During the later movement process, the folded box cardboard can maintain good flatness and enter the next process.

[0063] like Figure 7 As shown, the main body panels on one side of the folding box cardboard are usually two, therefore the second vacuum suction cup 41 is usually composed of a first vacuum suction cup and a second vacuum suction cup, with the two suction cups respectively adsorbing and pulling the two main body panels. Specifically, the first vacuum suction cup is mounted on the suction cup frame 22 via a first vacuum suction cup mounting base. One end of the first vacuum suction cup mounting base is rotatably connected to the suction cup frame 22, and the other end is rotatably connected to the movable end of the first cylinder on the suction cup frame 22. The second vacuum suction cup is fixed on the second vacuum suction cup mounting base, which is rotatably connected to both the first vacuum suction cup mounting base and the movable end of the second cylinder. The second cylinder is fixed on the first vacuum suction cup mounting base.

[0064] like Figure 5 As shown, when cylinder number one actuates, vacuum suction cups number one and two rotate synchronously around the hinge point between the mounting base of vacuum suction cup number one and suction cup frame 22. Furthermore, driven by cylinder number two, vacuum suction cup number two also rotates around the hinge point with the mounting base of vacuum suction cup number one. Therefore, the suction surfaces of vacuum suction cups number one and number two can have different inclinations. For stacked folded cardboard boxes, the inclination angles of the two main panels on the same side are different. Therefore, using two vacuum suction cups with different inclination angles to suction and pull the panels is the most effective method. Vacuum suction cup number one suctions the first main panel connected to the main cardboard, and vacuum suction cup number two suctions the outermost main panel.

[0065] Example 3

[0066] This embodiment discloses a feeding device suitable for a folding box mounting machine. Based on the above embodiment 1 or embodiment 2, refer to the appendix of the instruction manual. Figure 1 , Figure 2As shown in Figure 6, a paper feeding assembly 5 is provided in the hopper 1. The paper feeding assembly 5 includes a main lifting mechanism 51 set on the hopper frame and a material platform 52 assembled on the main lifting mechanism 51. The main lifting mechanism 51 drives the material platform 52 to move up and down reciprocally. Several folded cardboard boxes are stacked on the material platform 52.

[0067] Further, refer to the appendix to the instruction manual. Figure 6 As shown, the main lifting mechanism 51 includes a main lifting power source 511 fixed on the hopper frame and a main transmission unit 512 connected to the main lifting power source 511. The main transmission unit 512 is in two sets and is symmetrically distributed on the left and right sides of the material platform 52. Under the driving action of the main lifting power source 511, the main transmission unit 512 drives the material platform 52 to move up and down reciprocally.

[0068] Furthermore, the main drive unit 512 can be a sprocket and chain assembly or a pulley assembly. However, considering the internal space of the equipment and the magnitude of the force, a sprocket and chain assembly is generally chosen. Two sets of first sprocket and chain assemblies are symmetrically distributed on the left and right sides of the material platform 52, and each sprocket's rotation shaft is additionally equipped with a main lifting sprocket. A main lifting chain 12 is engaged on this lifting sprocket. One end of the main lifting chain 12 is connected to the material platform 52, and the other end is a free end. In order to prevent the chain from swaying randomly, a counterweight is provided on the free end of the main lifting chain 12. The structures of the sprocket and chain assembly and the pulley assembly are well-known technologies and will not be described in detail here.

[0069] Understandably, the two sets of sprocket and chain assemblies distributed on the left and right sides of the material platform 52 are usually connected as a whole by a synchronous drive shaft and installed on the material hopper frame. Then, one end of the synchronous drive shaft is connected to the main lifting power source 511 to drive the sprocket and chain assemblies on both sides to move synchronously, ensuring the consistency of their movements and thus ensuring the stability of the lifting of the material platform 52.

[0070] The main lifting power source 511 drives the synchronous transmission shaft to rotate, which in turn drives the sprocket and chain assemblies on both sides to rotate synchronously. The lifting sprockets on the sprocket and chain assemblies move together with the sprocket and chain assemblies, and finally the lifting chain on the lifting sprocket drives the material platform 52 connected to it to move up and down reciprocally.

[0071] In the embodiments described in this utility model, in order to ensure the stability of the material platform's up and down movement, a guide device 13 is provided on the hopper frame. The guide device 13 consists of a guide wheel and a guide rod. The two ends of the guide rod are fixed to the upper and lower ends of the hopper frame. The guide wheel is mounted on the material platform, and the guide rod slides in cooperation with the groove of the guide wheel.

[0072] In the embodiments described in this utility model, the main lifting power source 511 is usually a servo motor, hydraulic motor or other components. This utility model does not limit the specific structural form of the main lifting power source 511, as long as it can drive the main transmission unit 512 to move.

[0073] Example 4

[0074] This embodiment discloses a feeding device suitable for a folding box mounting machine. Based on embodiment 3, in order to achieve the effect of feeding paper without stopping the machine, the material bin 1 is further provided with a secondary lifting mechanism 7 and a material transfer mechanism 8. The secondary lifting mechanism 7 includes a secondary lifting power source 71 set on the material bin frame and a secondary transmission unit 72 connected to the secondary lifting power source 71. The secondary transmission unit 72 is in two sets and is symmetrically arranged on the left and right sides of the material platform 52. The material transfer mechanism 8 is connected to the secondary transmission unit 72. The main transmission unit 512 drives the material platform 52 to rise. When the material platform 52 and the material transfer mechanism 8 are on the same horizontal line, the secondary lifting power source 71 drives the secondary transmission unit 72 to move, driving the material transfer mechanism 8 to rise and transferring the material on the material platform 52 to the material transfer mechanism 8.

[0075] In the embodiments described in this utility model, the structure of the auxiliary transmission unit 72 is basically the same as that of the main transmission unit 512. That is, the auxiliary transmission unit 72 can be a sprocket and chain assembly or a pulley assembly, but considering the internal space of the equipment and the magnitude of the force, a sprocket and chain assembly is generally chosen. Two sets of second sprocket and chain assemblies are symmetrically distributed on the left and right sides of the material platform 52, and an auxiliary lifting sprocket is additionally provided on the rotating shaft of each sprocket. An auxiliary lifting chain 13 is engaged on the auxiliary lifting sprocket. One end of the auxiliary lifting chain 13 is connected to the material transfer mechanism 8, and the other end is a free end. In order to prevent the auxiliary lifting chain 13 from shaking randomly, a counterweight is provided on the free end of the auxiliary lifting chain 13.

[0076] Further, refer to the appendix to the instruction manual. Figure 6As shown, the material transfer mechanism 8 includes a fork 81 and a fork support frame 82. The fork support frame 82 is composed of two support beams arranged opposite to each other. The fork support frame 82 is connected to the auxiliary transmission units 72 on both sides respectively. A tray 9 is provided on the material platform 52. Folded cardboard boxes to be lined with inner paper are stacked on the tray 9. The upper support surface of the tray 9 has strip-shaped grooves 10 that cooperate with the fork 81. The fork support frame 82 is located directly above the tray 9, and the horizontal projection of the tray 9 is located within the horizontal projection of the fork support frame 82. The main drive unit 512 moves to lift the material platform 52, and the pallet on the material platform 52 rises together. When the pallet 9 passes through the inside of the fork support frame 82 and the bottom of the groove 10 on the pallet 9 is at the same level as the upper surface of the fork support frame 82, the fork 81 is pushed into the groove 10 and the two ends of the fork 81 are supported on the fork support frame 82. Then the auxiliary lifting power source 71 drives the auxiliary drive unit 72 to move, which in turn lifts the fork support frame 82.

[0077] In the embodiments described in this utility model, the secondary lifting power source 71 is usually a servo motor, hydraulic motor or other components. This utility model does not limit the specific structural form of the main lifting power source 511, as long as it can drive the secondary transmission unit 72 to move.

[0078] In the embodiments described in this utility model, the fork 81 is inserted into the strip groove 10 of the tray 9 by means of manual labor or a robotic arm.

[0079] In the embodiments described in this utility model, the basic working principle of the entire paper feeding assembly 5 is as follows: When feeding, the worker or robot first stacks the folded box cardboard to be lined with inner paper on the upper support surface of the pallet 9, and then uses a forklift or other handling tools to transport the pallet 9 to the silo 1, and then moves the pallet 9 to the material platform 52. Next, the main lifting mechanism 51 operates, driving the material platform 52 and the pallet 9 on the material platform 52 to rise together via the main lifting chain 12. When the pallet 9 is lifted to the point where the bottom of the groove 10 on the upper support surface is at the same level as the upper surface of the fork support frame 82, the main lifting mechanism 51 stops operating. At this time, the fork 81 is pushed into the groove from one side, and both ends of the fork 81 are supported on the fork support frame 82. Then the main lifting mechanism can move in the opposite direction, driving the material platform 52 and the pallet 9 to fall together via the main lifting chain 12. After the pallet 9 falls, the fork 81 supports the folded cardboard boxes stacked on the pallet 9. Then the auxiliary lifting mechanism 7 operates, lifting the fork support frame 82 and the fork 81 upward via the auxiliary lifting chain 13. Subsequently, driven by the pulley assemblies on both sides, the suction cup frame beam 21 reciprocates between the material picking position and the material placing position. When it reaches the material picking position, the lifting mechanism 23 drives the suction cup frame 22 to descend as a whole. The suction cup frame 22 extends into the material bin 1 and then picks up a folded box cardboard sheet to be lined with inner paper from the tray 9. Specifically, during the material picking process, the first vacuum suction cup 3 adheres to the central main cardboard 100 and the side wings 300 on both sides of the folded box. At the same time, the second vacuum suction cup 41 rotates in the vertical plane towards the main body partition 200 until the suction surface of the second vacuum suction cup 41 is completely in contact with the surface of the main body partition 200. The second vacuum suction cup 41 then... The main body plate 200 is attracted, and then the second vacuum suction cup 41 rotates in the opposite direction, causing the main body plate 200 to rotate upward around the corresponding crease, pulling and stretching the inclined main body plate 200 until it is roughly on the same plane as the middle main cardboard 100. The adaptive adjustment mechanism 4 flattens the outer shell part of the folded box cardboard. The first vacuum suction cup 3 and the second vacuum suction cup 41 simultaneously attract the folded box cardboard. The lifting mechanism 23 drives the suction cup frame 22 to rise, and then the suction cup frame beam 21 drives the suction cup frame 22 to move to the feeding position. Then the lifting mechanism 23 moves again, the suction cup frame 22 descends, and the first vacuum suction cup 3 and the second vacuum suction cup 41 place the grabbed folded box cardboard on the receiving device 6. Then, driven by the suction cup frame beam 21, the picking component returns to the picking position, and the secondary lifting chain 13 drives the support fork 81 and the support fork support frame 82 to rise to a certain position, so that the vacuum suction cup can grab the folded box cardboard on the support fork 81. The above actions are repeated to complete the feeding.

[0080] After the material platform 52 returns to its initial position, remove the tray 9 above the material platform 52 and replace it with a new tray loaded with the folded box cardboard to be mounted. Then repeat the above actions to achieve the effect of feeding without stopping the machine.

[0081] It should be noted that after all the cardboard supported on the fork 81 is removed, the fork 81 is removed, and then the fork support frame 82 is lowered and reset. The newly installed pallet 9 on the material table 52 continues to rise until it reaches the specified height, and then the cardboard is transferred to the material transfer mechanism 8.

[0082] It is understandable that for the transfer of folding cardboard, the cardboard can be completely transferred to the fork 81 at the beginning, and then the vacuum suction cup can start to pick up the cardboard on the fork 81. Alternatively, the vacuum suction cup can first pick up the cardboard on the tray 9, pick up a certain amount, and when the tray just rises to the same level as the bottom of the groove 10 and the upper surface of the fork support frame 82, the remaining cardboard is then transferred to the fork 81. Then the material platform 52, along with the tray 9, descends together to replace the new tray on the material platform 52. Therefore, the specific timing of material transfer can be set according to the needs. This utility model does not make specific limitations on this part. All of the above methods can achieve the effect of feeding without stopping the machine.
