Description

Technical Field

[0001] The invention relates to the technical field of carton creasing machines, in particular to a carton creasing machine with a stacking device. Background Art

[0002] As we all know, the carton production process involves multiple steps, among which creasing is an extremely critical step. Using a creasing machine to press specific creases on the carton can ensure that the fold lines are clear and regular when the carton is subsequently folded into shape, thereby giving the carton good structural stability and aesthetics.

[0003] After searching, a Chinese patent disclosed a continuous production automatic feeding cardboard creasing machine, and its application publication number is CN112140642B. This patent has the advantage of not requiring manual adjustment of the cardboard position, saving manpower, and solving the problem that the existing creasing machine needs to manually adjust the position of the cardboard during operation, wasting a lot of manpower.

[0004] Traditional carton creasing machines usually only focus on completing the single function of creasing. In actual production scenarios, the cartons after creasing need to be collected and stacked manually or with the help of other auxiliary equipment. There are many disadvantages in manual collection and stacking of cartons. On the one hand, this requires a lot of manpower costs. Especially in the case of large-scale production, manual operation is not only inefficient, but also easily leads to worker fatigue and increases the possibility of errors. On the other hand, manual stacking makes it difficult to ensure the neatness and stability of the cartons. Problems such as uneven arrangement of cartons and tilted stacking may occur, which will cause inconvenience to subsequent packaging, transportation and warehousing.

[0005] Combining the above-mentioned problem points, it is found that although there are some equipment specifically used for carton stacking on the market, these equipment are often independent of the creasing machine. This means that in the production process, the cartons after creasing need to be transported from the creasing machine to the stacking equipment for stacking. This transportation process not only increases the complexity of the production process, but also, because the connection between different equipment requires manual intervention or the use of additional conveying devices, this further reduces the efficiency of the entire production process.

[0006] To this end, we propose a carton creasing machine with a stacking device which can automatically and orderly collect and stack the creasing cartons, reduce manual intervention and improve production efficiency. Summary of the invention

[0007] 1. Technical issues to be solved

[0008] In view of the deficiencies in the prior art, the present invention provides a carton creasing machine with a stacking device, which has the advantages of automatically and orderly collecting and stacking the creasing cartons, reducing manual intervention and improving production efficiency.

[0009] (II) Technical solution

[0010] The above technical objectives of the present invention are achieved through the following technical solutions: a carton creasing machine with a stacking device, comprising a creasing machine main body, a guide structure bolted to the front side of the creasing machine main body, and a stacking and collecting structure bolted to the front side of the guide structure, the guide structure comprising a support table, the support table is bolted to the front side of the creasing machine main body, the front and rear sides of the support table are rotatably connected to the first rotating shaft, and two first conveyor belts are sleeved between the surfaces of the two first rotating shafts, the inner wall of the first conveyor belt is in sliding contact with the surface of the support table, a plurality of elastic pressing sheets are arranged on the top of the support table, and the side of the elastic pressing sheet close to the creasing machine main body is bolted to it, the top of the support table is in rolling contact with the limiting wheel, and a mounting block is arranged on the top of the limiting wheel, a first return spring is arranged between the mounting block and the limiting wheel, two mounting rods are passed through the interior of the mounting block, and the mounting rods are bolted to the creasing machine main body;

[0011] The stacking and collecting structure includes a limiting component, and a stacking box is bolted to the front side of the limiting component, a conveying frame is bolted to the bottom of the front side of the stacking box, a supporting component is slidably arranged at the top inside the stacking box, and the supporting component is slidably connected to the limiting component, a pallet is placed on the top of the supporting component, a pressing component is arranged on the top of the supporting component, and the pressing component is used in conjunction with the supporting component.

[0012] The above technical solution is adopted by setting up the coordinated use of the guiding structure and the stacking and collecting structure. Unlike the traditional carton production process in which the creasing machine and the stacking equipment are independent of each other and require manual or additional conveying devices to connect, this integrated design enables the cartons to be directly and smoothly conveyed to the stacking and collecting structure for stacking through the guiding structure after the creasing is completed, without the need for additional processes such as intermediate transportation, thereby greatly shortening the time of the entire production process and effectively improving production efficiency. In addition, through the setting of the limiting components, supporting components and pressing components in the stacking and collecting structure, it is possible to adapt to the stacking needs of cartons of different sizes while ensuring that the cartons are arranged neatly, thereby ensuring the close arrangement and stable position of the cartons during the stacking process, and avoiding looseness or collapse between the cartons.

[0013] The present invention is further configured as follows: the limit assembly includes a connecting plate, the connecting plate is bolted between the guide structure and the side opposite to the stacking box, both sides of the top of the connecting plate are slidably connected to the limit plate, and a plurality of rollers are embedded in the opposite sides of the two limit plates, the bottom of the limit plate is bolted with a moving block, and the moving block is slidably arranged inside the connecting plate, a sliding rod passes through the inside of the moving block, and the bottom of the sliding rod is connected to the inner wall of the connecting plate, the front side of the moving block is provided with connecting teeth, the interior of the connecting teeth is provided with a positioning piece, and the positioning piece is arranged inside the connecting plate.

[0014] By adopting the above technical solution, by setting a limit assembly, when the guiding structure transports the carton support plate to between the two limit plates, it can automatically push the two limit plates to move in opposite directions, and synchronously drive the moving block to move on the surface of the slide rod, and at the same time, the connecting teeth and the positioning parts are used in coordination to fix the position of the moving block with the positioning parts, so that it can adapt to the size of the carton, and the movement of the two limit plates will simultaneously drive the pressing assembly to move, so that the pressing assembly automatically adjusts to the size of the corresponding carton, thereby adapting to the stacking needs of cartons of different sizes while ensuring that the cartons are arranged neatly, thereby ensuring the close arrangement and stable position of the cartons during the stacking process, and avoiding looseness or collapse between the cartons.

[0015] The present invention is further configured as follows: the positioning member includes a slide plate, which is slidably connected to the inside of a connecting plate, a movable shaft is provided on the top of the slide plate, and a positioning tooth is sleeved on the surface of the movable shaft, and the positioning tooth is located between two adjacent connecting teeth, two electric cylinders are bolted to the front side of the slide plate, and a fixed plate is bolted between the front sides of the two electric cylinders, a positioning plate is bolted to the top of the movable shaft, and a second return spring is bolted between the positioning tooth and the positioning plate.

[0016] By adopting the above technical solution, a positioning piece is set, and when the moving block drives the connecting tooth to move, the positioning tooth and the movable shaft are pushed to rotate, and the second reset spring is squeezed synchronously. When the moving block moves to the desired position, the elasticity of the second reset spring can make the positioning tooth clamped between the corresponding two adjacent connecting teeth, thereby locking the position of the moving block and the limit plate, which is convenient for the limit plate to limit the conveying path of the carton. When the position of the moving block needs to be unlocked, the slide plate can be driven to move to the fixed plate position by the movement of the electric cylinder, which can synchronously drive the positioning tooth to move out from between the two connecting teeth, thereby releasing the position lock of the moving block, facilitating the resetting of the two limit plates, and facilitating the limiting work of cartons of other sizes.

[0017] The present invention is further configured as follows: a non-return block is provided on one side of the positioning plate close to the inner wall of the positioning tooth, and the non-return block is in contact with the one side of the positioning tooth close to the positioning tooth.

[0018] By adopting the above technical solution, by setting a check block, an additional locking mechanism can be provided for the cooperation between the positioning teeth and the connecting teeth, effectively preventing the positioning teeth from accidentally disengaging from the connecting teeth when disturbed by external forces, and further enhancing the positioning effect of the positioning member on the limit plate.

[0019] The present invention is further configured as follows: a connecting block is bolted to one side of the limit plate close to the pressure assembly, and the connecting block extends to the interior of the pressure assembly on one side close to the pressure assembly and is in sliding contact with the pressure assembly; an inclined portion is provided on the side of the limit plate away from the connecting block, and the two inclined portions are symmetrically arranged.

[0020] By adopting the above technical solution, by setting a connecting block, the two limit plates can be moved and the two clamping plates can be driven to move through the connecting block at the same time, thereby achieving the effect of automatically adapting to the size of the carton, and through the sliding connection between the connecting block and the clamping plate, it is convenient for the connecting block to drive the movement of the clamping plate without affecting the normal up and down movement of the clamping plate.

[0021] The present invention is further configured as follows: the supporting assembly includes a hollow plate, the hollow plate is slidably arranged on the top of the stacking box, and movable plates are bolted on both sides of the hollow plate, the movable plates are slidably arranged on both sides of the stacking box, and an extrusion piece is bolted on the bottom of the movable plate, the bottom of the extrusion piece is bolted to a support plate, and the support plate is bolted to a side close to the stacking box, the front and rear sides of the hollow plate are rotatably connected to a second rotating shaft, and two second conveyor belts are sleeved between the surfaces of the two second rotating shafts, and the inner wall of the second conveyor belt is in sliding contact with the surface of the hollow plate.

[0022] The above technical solution is adopted, by setting a supporting component, the cartons are supported and placed by the pallet on the hollow plate, and as the number of cartons increases and the stacking height rises, the movable plate will be gradually squeezed downward, and at the same time, pressure will be generated on the extrusion member, so that the hollow plate will gradually enter the interior of the stacking box, so as to realize orderly stacking of the cartons, and through the connection between the hollow plate and the clamping plate, the clamping plate can be gradually driven to move downward, so that the limiting ability of the carton can be maintained at all times, and the compression of the extrusion member will squeeze the pre-stored air inside it, and squeeze the air pressure into the interior of the pressing member, so that the pressing component can always maintain the pressing strength of the carton. When the cartons are stacked to a certain height, the carton is pushed to the opening of the stacking box by the external cylinder structure on the pressing component, and the pallet together with the carton is moved out to the conveying rack in cooperation with the second rotating shaft and the second conveyor belt.

[0023] The present invention is further configured as follows: the extrusion part includes a pressure rod, the top of the pressure rod is connected to the movable plate, the bottom of the pressure rod surface is sleeved with a fixed cylinder, and the bottom of the fixed cylinder is connected to the support plate, a capsule is provided at the bottom inside the fixed cylinder, the bottom of the pressure rod is bolted with a pressure plate, and the pressure plate and the capsule are used in conjunction with the capsule, the surface of the fixed cylinder is respectively sleeved with a support ring and a support spring, and the side of the support spring close to the movable plate and the support ring is respectively connected to the two, the bottom of the fixed cylinder away from the stacking box is fixedly connected with a connecting pipe, and the connecting pipe is fixedly connected to the pressing assembly.

[0024] By adopting the above technical solution, by setting an extrusion piece, when the carton is placed on the pallet, the weight of the carton will be transmitted to the pressure rod through the pallet, and the pressure rod will then apply pressure to the bag through the pressure plate. Since air is pre-stored in the bag, when the pressure plate squeezes the bag to deform, its internal pressure change will be transmitted to the pressing component through the connecting pipe, so that the pressing component can apply appropriate pressing pressure to the carton according to the received pressure information, thereby achieving the synergistic effect in pressure between the supporting component and the pressing component, and jointly ensuring the close arrangement and stable state of the carton stacking, and when the movable plate squeezes the pressure rod to move, it will synchronously squeeze the support spring, and when the pallet and the carton are moved out of the hollow plate, due to the disappearance of weight, the hollow plate can be reset by utilizing the elasticity of the support spring, so as to facilitate the next supporting work.

[0025] The present invention is further configured as follows: the pressure assembly includes two clamps, the clamps are slidably arranged on both sides of the top of the hollow plate, the surfaces of the clamps are slidably sleeved with guide plates, the tops of the opposite sides of the two guide plates are bolted with sliders, and a sliding sleeve is slidably sleeved between the surfaces of the two sliders, the bottom of the sliding sleeve is bolted with a pressure piece, and the pressure piece is fixedly connected to the connecting pipe, the bottom of the pressure piece is bolted with a fixed block, and a pressure wheel is arranged at the bottom of the fixed block, and a third return spring is arranged between the fixed block and the pressure wheel.

[0026] By adopting the above technical solution, by setting a pressure piece, when the carton is placed on the pallet, the clamp can laterally position the two sides of the carton to prevent the carton from shifting in the lateral direction. When it is necessary to apply pressure to the carton, the pressure piece will act according to the pressure information transmitted from the connecting pipe and the actual stacking situation of the carton. As the number of cartons increases, the pressure piece will gradually increase the pressure on the carton to ensure that the cartons are closely arranged, and apply pressure to the carton through a pressure wheel. A second return spring is provided between the fixed block and the pressure wheel. The second return spring can automatically adjust the pressure according to the state of the carton to ensure that the pressure can ensure that the cartons are closely arranged without damaging the carton due to excessive pressure. Accurate positioning and stable pressure of the cartons during the stacking process are achieved, and the neatness and stability of the carton stacking are guaranteed.

[0027] The present invention is further configured as follows: the pressure piece includes a connecting pipe, the connecting pipe is fixedly connected to the connecting pipe, and the bottom of the connecting pipe is fixedly connected to a sleeve, a push rod is slidably arranged inside the sleeve, the bottom of the push rod is bolted to the fixed block, the top of the push rod is bolted to a push plate, and a reset tension spring is arranged between the push plate and the inner wall of the sleeve.

[0028] By adopting the above technical solution, by setting a pressure piece, when the cartons start to be stacked, as the number of cartons increases, the pressure transmitted from the supporting assembly will gradually increase, and the pressure enters the inside of the sleeve through the fixed connecting pipe, pushing the push rod to move downward, and the push rod drives the fixed block and the pressure wheel to apply a pressure downward to the carton. At this time, the reset spring will be stretched and store a certain elastic potential energy. When the number of cartons decreases or other conditions require adjustment of the pressure, the reset spring will use its stored elastic potential energy to quickly return to its original state, drive the push plate to move upward, and then move the push rod upward, reducing the pressure on the carton, thereby realizing the function of automatically adjusting the pressure according to the stacking situation of the cartons, ensuring effective pressure and positioning of the cartons, and improving the stability and reliability of the entire stacking process.

[0029] The present invention is further configured as follows: the surfaces of the first conveyor belt and the second conveyor belt are both provided with anti-slip patterns, and are arranged in an uneven manner.

[0030] By adopting the above technical solution, by setting uneven anti-slip patterns on the first conveyor belt and the second conveyor belt, the friction between the first conveyor belt and the second conveyor belt and the cartons can be effectively increased, preventing the cartons from sliding during transportation, and ensuring that the cartons can be transported smoothly and accurately.

[0031] (III) Beneficial effects

[0032] Compared with the prior art, the present invention provides a carton creasing machine with a stacking device, which has the following beneficial effects:

[0033] The carton creasing machine with a stacking device is different from the traditional carton production process in which the creasing machine and stacking equipment are independent of each other and require manual or additional conveying devices to connect them. This integrated design enables the cartons to be directly and smoothly conveyed to the stacking and collecting structure for stacking through the guiding structure after creasing, without the need for additional processes such as intermediate transportation, thereby greatly shortening the time of the entire production process and effectively improving production efficiency. In addition, by setting the limiting components, supporting components and pressing components in the stacking and collecting structure, it can meet the stacking needs of cartons of different sizes while ensuring that the cartons are arranged neatly, thereby ensuring the close arrangement and stable position of the cartons during the stacking process, and avoiding loosening or collapse between cartons.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example 1

[0045] See also Figure 1 , Figure 8 A carton creasing machine with a stacking device comprises a creasing machine body 1, a guide structure 2 is bolted to the front side of the creasing machine body 1, and a stacking collection structure 3 is bolted to the front side of the guide structure 2, the guide structure 2 comprises a support platform 21, the support platform 21 is bolted to the front side of the creasing machine body 1, the front and rear sides of the support platform 21 are rotatably connected with a first rotating shaft 22, and two first conveyor belts 23 are sleeved between the surfaces of the two first rotating shafts 22, the inner wall of the first conveyor belt 23 is in sliding contact with the surface of the support platform 21, a plurality of elastic pressing sheets 24 are arranged on the top of the support platform 21, and the elastic pressing sheet 24 is bolted to the side close to the creasing machine body 1, and the top of the support platform 21 is in rolling contact with the limited position wheel 2 5, and a mounting block 26 is arranged on the top of the limiting wheel 25, a first return spring 27 is arranged between the mounting block 26 and the limiting wheel 25, two mounting rods 28 are penetrated inside the mounting block 26, and the mounting rods 28 are bolted to the creasing machine body 1, and the guiding structure 2 and the stacking and collecting structure 3 are arranged for coordinated use. Different from the traditional carton production process in which the creasing machine and the stacking equipment are independent of each other and need to be connected manually or with an additional conveying device, this integrated design enables the cartons to be directly and smoothly conveyed to the stacking and collecting structure 3 for stacking through the guiding structure 2 after the creasing is completed, without the need for additional processes such as intermediate transportation, which greatly shortens the time of the entire production process and effectively improves the production efficiency.

[0046] Working principle of this embodiment: after the carton is indented by the indentation machine body 1, it will fall onto the support platform 21. When the carton is normally transported on the second conveyor belt 76, the limiting wheel 25 will roll with the movement of the carton, playing an auxiliary support and limiting role on the top of the carton, ensuring that the carton maintains a relatively stable position in the vertical direction, and preventing the carton from jumping up and down or tilting during transportation. When the carton may generate an upward impact force due to changes in the conveying speed, slight collisions with other components, etc., the limiting wheel 25 will compress the third return spring 98 upward under the action of the impact force. After being compressed, the third return spring 98 will store elastic potential energy, and at the same time absorb and buffer most of the impact force through its own elastic deformation, avoiding the impact force directly acting on the carton and causing damage to the carton. When the impact force disappears, the third return spring 98 will use the stored elastic potential energy to restore its original state, push the limiting wheel 25 back to its original position, and continue to provide auxiliary support and limit the carton, thereby ensuring the stability and integrity of the carton during transportation.

By setting the pressing piece 73, when the carton is placed on the pallet 8, the weight of the carton will be The pressure is transmitted to the pressure rod 731 through the support plate 8, and the pressure rod 731 further applies pressure to the capsule 733 through the pressure plate 734. Since there is air pre-stored in the capsule 733, when the pressure plate 734 squeezes the capsule 733 to cause deformation, its internal pressure change will be transmitted to the pressure component 9 through the connecting pipe 737, so that the pressure component 9 can apply appropriate pressure to the carton according to the received pressure information, thereby realizing the synergy between the supporting component 7 and the pressure component 9 in terms of pressure, and jointly ensuring the close arrangement and stable state of the carton stacking, and when the movable plate 72 squeezes the pressure rod 731 to move, it will synchronously squeeze the support spring 736, and when the support plate 8 and the carton are removed from the hollow plate 71, due to the disappearance of weight, the elasticity of the support spring 736 can be used to reset the hollow plate 71, so as to facilitate the next supporting work.

[0055] Among them, the pressing assembly 9 includes two clamping plates 91, which are slidably arranged on both sides of the top of the hollow plate 71, and the surface of the clamping plate 91 is slidably sleeved with a guide plate 92, and the tops of the opposite sides of the two guide plates 92 are bolted with a slider 93, and a sliding sleeve 94 is slidably sleeved between the surfaces of the two sliders 93, and a pressing piece 95 is bolted to the bottom of the sliding sleeve 94, and the pressing piece 95 is fixedly connected to the connecting pipe 737, and a fixing block 96 is bolted to the bottom of the pressing piece 95, and a pressing wheel 97 is arranged at the bottom of the fixing block 96, and a third return spring 98 is arranged between the fixing block 96 and the pressing wheel 97. By arranging the pressing piece 95, when the carton is placed on the pallet 8, the clamping plate 91 can laterally position the two sides of the carton to prevent the carton from being tilted horizontally When it is necessary to apply pressure to the carton, the pressure member 95 will act according to the pressure information transmitted from the connecting pipe 737 and the actual stacking situation of the cartons. As the number of cartons increases, the pressure member 95 will gradually increase the pressure on the cartons to ensure that the cartons are closely arranged, and apply pressure to the cartons through the pressure wheel 97. A second reset spring 477 is provided between the fixed block 96 and the pressure wheel 97. The second reset spring 477 can automatically adjust the pressure according to the state of the carton to ensure that the pressure can ensure that the cartons are closely arranged without damaging the cartons due to excessive pressure, thereby achieving accurate positioning and stable pressure on the cartons during the stacking process, and ensuring the neatness and stability of the carton stacking.

[0056] The pressure piece 95 includes a connecting pipe 951, which is fixedly connected to the connecting pipe 737, and a sleeve 952 is fixedly connected to the bottom of the connecting pipe 737. A push rod 953 is slidably arranged inside the sleeve 952. The bottom of the push rod 953 is bolted to the fixed block 96, and a push plate is bolted to the top of the push rod 953. A reset spring 954 is arranged between the push plate and the inner wall of the sleeve 952. By setting the pressure piece 95, when the cartons start to be stacked, as the number of cartons increases, the pressure transmitted from the supporting assembly 7 will gradually increase, and the pressure enters the interior of the sleeve 952 through the fixed connecting pipe 951, pushing The push rod 953 moves downward, and the push rod 953 drives the fixed block 96 and the pressure wheel 97 to apply pressure downward to the carton. At this time, the reset spring 954 will be stretched to store a certain amount of elastic potential energy. When the number of cartons decreases or other situations require adjustment of the pressure, the reset spring 954 will use its stored elastic potential energy to quickly return to its original state, drive the push plate to move upward, and then move the push rod 953 upward, reducing the pressure on the carton, thereby realizing the function of automatically adjusting the pressure according to the stacking conditions of the cartons, ensuring effective pressure and positioning of the cartons, and improving the stability and reliability of the entire stacking process.

[0057] Among them, the surfaces of the first conveyor belt 23 and the second conveyor belt 76 are both provided with anti-slip patterns, and are arranged in an uneven manner. By arranging uneven anti-slip patterns on the first conveyor belt 23 and the second conveyor belt 76, the friction between the first conveyor belt 23 and the second conveyor belt 76 and the cartons can be effectively increased, preventing the cartons from sliding during transportation, and ensuring that the cartons can be transported smoothly and accurately.

[0058] Working principle of this embodiment: when the guiding structure 2 conveys the carton support plate to between the two limiting plates 42, it can automatically push the two limiting plates 42 to move in opposite directions, and synchronously drive the moving block 44 to move on the surface of the slide rod 45, and at the same time, the connecting teeth 46 and the positioning members 47 are used in coordination, so that the positioning members 47 fix the position of the moving block 44, and adapt to the size of the carton. When the two limiting plates 42 move, they will synchronously drive the clamping plate 91 to move through the connecting block 11, so that the clamping plate 91 is automatically adjusted to the size of the corresponding carton, and then the carton is supported and placed by the supporting plate 8 on the hollow plate 71, and as the number of cartons increases and the stacking height rises, the movable plate 72 will be gradually squeezed downward and transmitted to the pressure rod 731, and the pressure rod 731 then passes through the pressure plate 73 4 applies pressure to the bladder 733. Since there is air in the bladder 733, when the pressure plate 734 squeezes the bladder 733 to deform, the internal pressure change will be transmitted to the pressure member 95 through the connecting tube 737, so that the push rod 953 moves in the sleeve 952, and applies pressure to the pressure wheel 97 to ensure the stability of the carton stacking. When the stacking reaches a certain height, the cylinder structure (not shown in the figure) externally connected to the pressure component 9 pushes the carton to the opening of the stacking box 5, and in cooperation with the second rotating shaft 75 and the second conveyor belt 76, the support plate 8 together with the carton is moved out to the conveying frame 6, and then the push of the external cylinder structure is released. Under the elasticity of the supporting spring 736, the hollow plate 71 and other structures are reset to carry out the next stacking work.
