Description

Technical Field

[0001] This utility model relates to the field of cardboard splicing technology, specifically a cardboard splicing machine of different sizes. Background Technology

[0002] Paperboard, also known as board paper, is a thick sheet of paper made from various pulps and composed of interwoven fibers. The difference between paperboard and paper is usually distinguished by basis weight and thickness. Generally, paper with a basis weight of more than 250g / m2 and a thickness of more than 0.5mm is called paperboard (alternatively, paper with a thickness of more than 0.1mm is generally called paperboard, and paper with a basis weight of less than 250g / m2 is generally considered paper, while paper with a basis weight of 250g / m2 or more is considered paperboard).

[0003] For example, Chinese utility model patent CN223302301U provides a paper box gray board splicing machine, which includes a frame and a feeding mechanism. The feeding mechanism includes two trays and a limiting plate. Each limiting plate and tray is fixedly installed on the top of the frame. A push block is movably embedded between the outer walls of the two limiting plates. A U-shaped frame is fixedly installed between the outer walls of the two limiting plates. A discharge port is opened at the bottom of the U-shaped frame. Four fixing plates are fixedly connected to the inner wall of the U-shaped frame. The trays and limiting plates are installed at an angle. The trays and limiting plates facilitate the placement of paper box gray boards. The push block facilitates the stable placement of gray boards between the trays and limiting plates. At the same time, it facilitates pushing the gray board closest to the U-shaped frame to the discharge port. Under the action of the fixing plate, the mounting rod, the positioning plate and the spring, the limiting plate will be located above the discharge port to close the discharge port and prevent gray boards with a width smaller than the discharge port from continuously and uncontrollably falling into the discharge port, thereby improving the safety of gray board splicing.

[0004] In the process of cardboard processing, splicing machines are needed to splice cardboard together. However, existing splicing machines can usually only splice cardboard of the same size, and it is difficult to splice two cardboards of different sizes. This not only reduces the splicing efficiency of cardboard of different sizes, but also affects the performance of the splicing machine. Summary of the Invention

[0005] The purpose of this invention is to provide a splicing machine for large and small cardboard to solve the problem of low splicing efficiency of large and small cardboard mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cardboard splicing machine, comprising a small cardboard feeding line, a cardboard splicing translational linear module, a large and small cardboard splicing assembly, a cardboard unloading assembly, a large cardboard feeding assembly, a cardboard pressure roller assembly, a fixed-length moving synchronous belt conveyor, a reinforcing iron sheet riveting assembly, a small cardboard flanging pre-folding assembly, an automatic hot melt adhesive spray gun, a small cardboard flanging pressure holding assembly, and a limiting assembly; the small cardboard feeding line is equipped with the cardboard splicing translational linear module; the cardboard splicing translational linear module is equipped with the large and small cardboard splicing assembly, the cardboard unloading assembly, and a large cardboard storage unit. A cardboard feeding assembly; the large cardboard feeding assembly is equipped with a cardboard pressure roller assembly; the cardboard pressure roller assembly is equipped with a fixed-length moving synchronous belt conveyor, a reinforcing iron sheet riveting assembly, a small cardboard edge-folding pre-folding assembly, an automatic hot melt adhesive spray gun, and a small cardboard edge-folding pressure holding assembly; the output end of the cardboard pressure roller assembly is connected to the input end of the fixed-length moving synchronous belt conveyor, and a limit component is provided on the fixed-length moving synchronous belt conveyor; the positions of the reinforcing iron sheet riveting assembly, the small cardboard edge-folding pre-folding assembly, the automatic hot melt adhesive spray gun, and the small cardboard edge-folding pressure holding assembly are gradually arranged closer to the fixed-length moving synchronous belt conveyor.

[0007] Preferably, the cardboard feeding line is a single-step driven synchronous belt conveyor line, and the synchronous belt is provided with positioning blocks for fixing the cardboard at fixed intervals.

[0008] Preferably, the cardboard splicing assembly consists of a base, a liftable suction cup for gripping small cardboard, and a liftable and lateral suction cup for gripping large cardboard.

[0009] Preferably, the cardboard feeding assembly is equipped with a liftable cardboard gripping suction cup.

[0010] Preferably, the large cardboard feeding assembly consists of a liftable tray with linear guide rails and a lifting mechanism composed of a servo motor driving sprockets and chains.

[0011] Preferably, the cardboard pressure roller assembly is provided with two rows of liftable brackets with guide optical shafts, and the brackets are provided with multiple sets of rubber-coated roller bearings.

[0012] Preferably, the reinforcing iron sheet riveting assembly consists of a frame A, two sets of lifting cylinders, and two sets of gripper cylinders. The lifting cylinders are fixed on the frame A, and the gripper cylinders are fixed at the ends of the lifting cylinders.

[0013] Preferably, the small cardboard edge-folding pre-folding assembly consists of a frame B, a cylinder-driven lifting mold, and a cylinder-driven horizontal moving mold.

[0014] Preferably, the limiting component includes a fixed plate, a limiting plate, a sliding groove, and a sliding block; two fixed plates are symmetrically fixed on a fixed-length moving synchronous belt conveyor; a plurality of limiting plates are arranged in a linear array between the two fixed plates, and the limiting plates are rotatably connected to the two fixed plates via a rotating shaft; a plurality of sliding grooves are linearly arranged on the opposite surfaces of the two fixed plates; the sliding block slides through the sliding groove and is fixedly connected to the limiting plate.

[0015] Preferably, the limiting plate is an inclined structure, with its high end positioned closer to the cardboard pressure roller assembly and its low end positioned away from the cardboard pressure roller assembly. The sliding groove is an arc-shaped structure, with its center located on the axis of rotation.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model involves manually placing small cardboard pieces, reinforced with iron plates, between positioning blocks on a small cardboard feeding line. Once the conveyor detects that the cardboard at the end of the line has been picked up, the line automatically moves one position and aligns the cardboard with the picking position. The cardboard splicing translational linear module, the large and small cardboard splicing assembly, and the cardboard unloading assembly move between different workstations to splice the large and small cardboard pieces and move them to the next workstation. Simultaneously, the spliced ​​cardboard is moved to a fixed-length synchronous conveyor belt. Two sets of suction cups descend and pick up the large and small cardboard pieces, which are then moved to the next workstation under the drive of the cardboard splicing translational linear module. Finally, a glue gun fixed to the frame is used to glue the overlapping area of ​​the large cardboard and the small cardboard. In the glue application process, when the large and small cardboards reach the next station, they descend simultaneously and are pressed together. Driven by the cardboard splicing translational linear module, the spliced ​​cardboard is picked up and brought to the fixed-length moving synchronous belt conveyor line. The large cardboard is picked up by the large cardboard feeding component, and the pallet automatically rises to the preset position. After the cardboard is used up, it automatically descends to the bottom and reminds the operator to reload. The small cardboard folding and pressure-holding component is the same as the small cardboard folding and pre-folding component. After pressing the folded edge, it is pressed for a period of time to ensure that the glue is firmly attached. Compared with the existing technology, this utility model has a simple and reasonable structure and ingenious design, which facilitates the splicing of two different sizes of cardboard, with high splicing efficiency and good use effect.

[0017] 2. This utility model, by setting a limiting component, allows the spliced ​​cardboard of different sizes to be conveyed to a fixed-length moving synchronous belt conveyor line. The spliced ​​cardboard of different sizes will squeeze the limiting plate, causing the limiting plate to rotate through the rotating shaft. This causes the sliding block to slide in the sliding groove until the bottom surface of the limiting plate contacts the spliced ​​cardboard of different sizes. At this time, the vertical direction of the spliced ​​cardboard of different sizes can be limited by the weight of the limiting plate itself, preventing it from shifting due to factors such as equipment vibration, which would affect the splicing effect of the cardboard of different sizes. Since the limiting plate is an inclined structure, it is convenient for the spliced ​​cardboard of different sizes to contact the inclined surface of the limiting plate, causing the limiting plate to rotate. Since the sliding groove is an arc-shaped structure, it is convenient to limit the rotation range of the limiting plate. Attached Figure Description

The cardboard pressure roller assembly 6 is equipped with two rows of liftable supports with guide shafts, and multiple sets of rubber-coated roller bearings are installed on the supports. These supports are spring-loaded and pressed against the fixed-length moving synchronous belt conveyor 7 to fix the large cardboard and prevent displacement during movement. The reinforcing iron sheet riveting assembly 8 consists of a frame A, two sets of lifting cylinders, and two sets of gripper cylinders. The lifting cylinders are fixed to the frame A, and the gripper cylinders are fixed to the ends of the lifting cylinders. During operation, the gripper cylinders first close to reinforce the iron sheet. The grippers of the iron sheet are bent, then the lifting cylinder descends to flatten the grippers, and then resets; the small cardboard edge-folding pre-folding assembly 9 consists of frame B, a cylinder-driven lifting mold, and a cylinder-driven horizontal moving mold. During operation, the lifting mold first moves to fold the cardboard at 45 degrees, then the horizontal mold folds the edge at 90 degrees. After holding the pressure for a period of time, the mold resets; the hot melt glue automatic spray gun 10 automatically applies glue as the cardboard passes by; the small cardboard is the product, with pre-processed holes for installing reinforcing iron sheets, which are manually inserted into the cardboard; the large cardboard has creases, and there are protruding cardboard pieces at the junction of the side and the small cardboard.

[0022] This invention involves manually placing small cardboard pieces, reinforced with iron plates, between positioning blocks on the small cardboard feeding line 1. Once the conveyor detects that the cardboard at the end of the line has been picked up, the line automatically moves one position and aligns the cardboard with the picking position. The cardboard splicing translational linear module 2, the large and small cardboard splicing assembly 3, and the cardboard unloading assembly 4 move between different workstations, splicing the large and small cardboard pieces and moving them to the next workstation. Simultaneously, the spliced ​​cardboard is moved to the fixed-length synchronous conveyor belt 7. After two sets of suction cups descend and pick up the large and small cardboard pieces, they move to the next workstation under the drive of the cardboard splicing translational linear module 2. Finally, a glue gun fixed to the frame applies glue to the overlapping area of ​​the large cardboard and the small cardboard. When the large and small cardboards reach the next station, they descend simultaneously and are pressed together. Driven by the cardboard splicing translation linear module 2, the spliced ​​cardboard is picked up and brought to the fixed-length moving synchronous belt conveyor line 7. The large cardboard is picked up by the large cardboard feeding component 5, and the pallet automatically rises to the preset position. After the cardboard is used up, it automatically descends to the bottom and reminds the operator to reload. The small cardboard folding and pressure holding component 11 is the same as the small cardboard folding and pre-folding component 9. After pressing the folded edge, it is pressed for a period of time to ensure that the adhesive is firmly attached. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design, which makes it easy to splice two different sizes of cardboard. The splicing efficiency is high and the use effect is good.

[0023] In a preferred embodiment, the limiting component 12 includes a fixed plate 1201, a limiting plate 1202, a sliding groove 1203, and a sliding block 1204; two fixed plates 1201 are symmetrically fixed on the fixed-length moving synchronous belt conveyor 7; three limiting plates 1202 are arranged in a linear array between the two fixed plates 1201, and the limiting plates 1202 are rotatably connected to the two fixed plates 1201 through a rotating shaft; six sliding grooves 1203 are linearly arranged on the opposite surfaces of the two fixed plates 1201; the sliding block 1204... 204 slides through the sliding groove 1203 and is fixedly connected to the limiting plate 1202; the limiting plate 1202 is an inclined structure, with the high end of the limiting plate 1202 facing closer to the cardboard pressure roller assembly 6 and the low end of the limiting plate 1202 facing away from the cardboard pressure roller assembly 6; the sliding groove 1203 is an arc structure, with the center of the sliding groove 1203 located on the axis of rotation; when the sliding block 1204 contacts the inner wall of the sliding groove 1203, there is a gap between the limiting plate 1202 and the fixed-length moving synchronous belt conveyor 7.

[0024] This utility model, by setting a limiting component 12, allows the spliced ​​cardboard of different sizes to be conveyed onto the fixed-length moving synchronous belt conveyor line 7. The spliced ​​cardboard of different sizes will squeeze the limiting plate 1202, causing the limiting plate 1202 to rotate via the rotating shaft. This causes the sliding block 1204 to slide within the sliding groove 1203 until the bottom surface of the limiting plate 1202 contacts the spliced ​​cardboard of different sizes. At this point, the vertical direction of the spliced ​​cardboard of different sizes can be restricted by the weight of the limiting plate 1202 itself, preventing it from shifting due to factors such as equipment vibration, which would affect the splicing effect of the cardboard of different sizes. Since the limiting plate 1202 has an inclined structure, it is convenient for the spliced ​​cardboard of different sizes to contact the inclined surface of the limiting plate 1202, causing the limiting plate 1202 to rotate. Since the sliding groove 1203 has an arc-shaped structure, it is convenient to restrict the rotation range of the limiting plate 1202.

[0025] Working Principle: During operation, a small cardboard piece with a reinforcing iron plate is manually placed between the positioning blocks on the small cardboard feeding line 1. Once the conveyor detects that the cardboard at the end of the line has been picked up, the line automatically moves one position and aligns the cardboard with the picking position. The cardboard splicing translational linear module 2, the large and small cardboard splicing assembly 3, and the cardboard unloading assembly 4 move between different workstations, splicing the large and small cardboard pieces together and moving them to the next workstation. Simultaneously, the spliced ​​cardboard is moved to the fixed-length synchronous conveyor belt 7. Two sets of suction cups descend and pick up the large and small cardboard pieces, which are then moved to the next workstation under the drive of the cardboard splicing translational linear module 2. A glue gun fixed to the frame applies glue to the overlapping area of ​​the large and small cardboard pieces. When the large and small cardboard pieces reach the next workstation, they descend simultaneously and are pressed together. The spliced ​​cardboard is then picked up by the cardboard splicing translational linear module 2 and placed... The large cardboard is picked up by the large cardboard feeding component 5 and the tray automatically rises to the preset position. After the cardboard is used up, it automatically descends to the bottom and reminds the operator to reload. The small cardboard folding and pressure holding component 11 is the same as the small cardboard folding and pre-folding component 9. After pressing the folded edge, it holds the pressure for a period of time to ensure that it is firmly pasted. When the spliced ​​large and small cardboards are conveyed to the fixed-length moving synchronous belt conveyor 7, the spliced ​​large and small cardboards will squeeze the limiting plate 1202, causing the limiting plate 1202 to rotate through the rotating shaft, so that the sliding block 1204 slides in the sliding groove 1203 until the bottom surface of the limiting plate 1202 contacts the spliced ​​large and small cardboards. At this time, the vertical direction of the spliced ​​large and small cardboards can be restricted by the weight of the limiting plate 1202 itself, so as to prevent them from shifting due to equipment vibration and other factors, which would affect the splicing effect of the large and small cardboards.

[0026] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
