Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paperboards and relates to a flattening device, in particular to a corrugated paperboard flattening device. Background Art

[0002] Corrugated boxes are rigid paper containers made of corrugated cardboard. They are the most widely used packaging products. Their usage has always been the highest among all packaging products and they are used in almost all fields. Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated cardboard and double corrugated cardboard. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation.

[0003] The current cardboard is severely warped after being balanced with moisture under natural conditions, which is not convenient for die-cutting. Therefore, the cardboard needs to be flattened by a flattening device. The current cardboard flattening device has the following disadvantages: unreliable fixation of the cardboard and uneven force on the cardboard during the flattening process. The above disadvantages seriously affect the effect of cardboard flattening.

[0004] After searching, it is found that a cardboard flattening device is disclosed in Chinese patent literature [Application No.: 201720118275.4; Publication No.: CN 206446190 U]. This device includes a bottom plate, a cavity is arranged inside the bottom plate, and the cavity is connected to the top of the bottom plate through a plurality of through holes. Support plates are arranged on both sides of the bottom plate, and a crossbeam and a rotating shaft are arranged in parallel across the two support plates. A cylinder and a rod body with a sealed sliding sleeve are arranged on the crossbeam, and the cylinder body is connected to the cavity through a pipeline. A rack is arranged at the bottom of the rod body, and a pressure plate is arranged at the bottom of the rack. The two ends of the rotating shaft are respectively rotatably connected to the corresponding support plates, and a gear meshing with the rack is fixedly provided on the rotating shaft. The cardboard flattening device of this structure has the advantage of improving the cardboard flattening effect.

[0005] The cardboard flattening device disclosed in the patent has the advantage of improving the cardboard flattening effect. However, the device flattens the corrugated cardboard by manually driving the pressing plate. This flattening method may result in excessive or insufficient force, thereby flattening the gaps in the corrugated cardboard, or failing to flatten the raised parts. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned problems in the existing technology and to propose a corrugated cardboard flattening device. The technical problem to be solved by the utility model is: how to achieve the problem of flattening the corrugated cardboard without applying excessive force to flatten the gaps in the corrugated cardboard.

[0007] The purpose of the present utility model can be achieved by the following technical solutions:

[0008] A corrugated cardboard flattening device includes support legs, on which a workbench is fixed. Two fixing frames are fixed on the workbench. A wire guiding wheel is rotatably connected to one of the fixing frames. Slide rails are fixed on both fixing frames. A support plate is slidably connected between the two slide rails. A placement groove is provided on the support plate, and a counterweight is placed in the placement groove. Two brackets are fixed on the support plate, and a pressing wheel is rotatably connected between the two brackets. A cavity is provided in the workbench, a winding assembly is arranged in the cavity, a pulling rope is arranged on the winding assembly, and the other end of the pulling rope bypasses the wire guiding wheel and is fixed to the support plate. A slideway is provided on the workbench, and a pressing plate is arranged on the workbench. A rack is fixed on the pressing plate, and the rack is slidably connected to the slideway. A driving assembly is arranged in the cavity, and the driving assembly is connected to the rack. An adsorption assembly is arranged in the pressing plate.

[0009] The working principle of the present utility model is as follows: First, place the corrugated cardboard on the pressing plate, and then adsorb the corrugated cardboard through the adsorption assembly to prevent the corrugated cardboard from shifting during flattening. After fixation, loosen the winding assembly. Under the action of gravity of the counterweight and the support plate, the pulling rope slides on the wire guiding wheel, and the support plate moves downward. While moving, it slides in the slide rail, so that the pressing wheel contacts the upper surface of the corrugated cardboard under its own gravity. Moreover, the gravity of the pressing wheel on the corrugated cardboard can be adjusted by increasing or decreasing the counterweight in the placement groove, so as to ensure that the pressing wheel does not move down too much to flatten the gap of the corrugated cardboard. At this time, start the driving assembly, and the driving assembly meshes with the rack, so as to drive the pressing plate to move left and right through the rack, thereby flattening the corrugated cardboard on the pressing plate.

[0010] The winding assembly includes a rotating rod, which is rotatably connected to the cavity. A motor I is fixed on the workbench, and the output shaft end of the motor I is fixed to the rotating rod. A wire winding wheel is fixed to the other end of the rotating rod, and the wire winding wheel is connected to the pulling rope.

[0011] With the above structure, when it is necessary to replace the flattened corrugated cardboard, start the motor I. The motor I drives the rotating rod to rotate. While the rotating rod rotates, it drives the wire guiding wheel to wind the pulling rope. The pulling rope slides on the wire guiding wheel, and while sliding, it pulls the support plate upward, separating the pressing wheel from the corrugated cardboard. Then take out the flattened corrugated cardboard, place a corrugated cardboard to be flattened, and then reverse the motor I to make the wire guiding wheel contact the corrugated cardboard again.

[0012] The driving assembly includes a fixed seat, which is fixed to the cavity. A motor II is fixed on the fixed seat, and a gear is fixed to the output shaft end of the motor II. The gear meshes with the rack.

[0013] With the above structure, by starting the second motor, the second motor drives the gear to rotate. While the gear is rotating, it meshes with the rack, thereby driving the rack to slide in the slideway, so that the pressing plate can move back and forth, facilitating the pressing wheel to flatten the corrugated cardboard.

[0014] The adsorption assembly includes a suction fan. The suction fan is embedded in the pressing plate. The pressing plate is embedded with a suction air pipe. The suction air pipe is fixedly connected to the suction fan. A number of uniformly distributed suction air outlets are provided in the pressing plate, and the suction air pipe is communicated with the suction air outlets.

[0015] With the above structure, after the corrugated cardboard is placed on the pressing plate, the suction fan is started. The suction fan adsorbs the corrugated cardboard on the pressing plate through the suction air pipe and the suction air outlets, preventing the problem of the position of the corrugated cardboard shifting during flattening.

[0016] Through holes are provided on both the fixed frame and the slide rail, and inserting rods are slidably connected in the through holes.

[0017] With the above structure, by inserting the inserting rod into the through hole, the position of the support plate can be limited, preventing the problem of the support plate moving upward during flattening.

[0018] A limiting plate is fixed at the upper end of the slide rail.

[0019] With the above structure, the limiting plate fixed on the slide rail can prevent the support plate from moving upward too much and thus detaching from the slide rail.

[0020] Compared with the prior art, the corrugated cardboard flattening device has the following advantages:

[0021] 1. First, place the corrugated cardboard on the pressing plate, and then adsorb the corrugated cardboard through the adsorption assembly, thereby preventing the corrugated cardboard from shifting during flattening. After fixation, release the winding assembly. Under the action of gravity of the counterweight and the support plate, the pulling rope slides on the wire pulley, and the support plate moves downward. While moving, it slides in the slide rail, so that under its own gravity, the pressing wheel contacts the upper surface of the corrugated cardboard. Moreover, the gravity exerted by the pressing wheel on the corrugated cardboard can be adjusted by increasing or decreasing the counterweight in the placement groove, thus ensuring that the pressing wheel does not move downward too much and flatten the gaps of the corrugated cardboard. At this time, start the driving assembly. The driving assembly meshes with the rack, thereby driving the pressing plate to move left and right through the rack, so as to flatten the corrugated cardboard on the pressing plate.

[0022] 2. When it is necessary to replace the flattened corrugated cardboard, start Motor 1. Motor 1 drives the rotating rod to rotate. While the rotating rod is rotating, it drives the wire pulley to wind up the pulling rope. The pulling rope will slide on the wire pulley and pull the support plate upward at the same time, separating the pressing wheel from the corrugated cardboard. Then take out the flattened corrugated cardboard and place a corrugated cardboard to be flattened. Then reverse Motor 1 to make the wire pulley contact the corrugated cardboard again.

[0023] 3. By starting Motor 2, Motor 2 drives the gear to rotate. While the gear is rotating, it meshes with the rack, thereby driving the rack to slide in the slideway, so that the pressing plate can move back and forth, facilitating the pressing wheel to flatten the corrugated cardboard.

[0028] The following are specific embodiments of the present utility model and in combination with the drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0029] As Figures 1 - 3As shown in the figure, the corrugated cardboard flattening device includes support legs 1. A workbench 2 is fixed on the support legs 1. Two fixing frames 3 are fixed on the workbench 2. A wire guiding wheel 4 is rotatably connected to one of the fixing frames 3. Slide rails 5 are fixed on both fixing frames 3. A support plate 6 is slidably connected between the two slide rails 5. A placing groove is formed in the support plate 6, and a counterweight 23 is placed in the placing groove. Two brackets 7 are fixed on the support plate 6. A pressing wheel 8 is rotatably connected between the two brackets 7. A cavity is formed in the workbench 2. A winding assembly is arranged in the cavity. A pulling rope 14 is arranged on the winding assembly. The other end of the pulling rope 14 bypasses the wire guiding wheel 4 and is fixedly connected to the support plate 6. A slideway is formed on the workbench 2. A pressing plate 9 is arranged on the workbench 2. A rack 10 is fixed on the pressing plate 9. The rack 10 is slidably connected to the slideway. A driving assembly is arranged in the cavity. The driving assembly is connected to the rack 10. An adsorption assembly is arranged in the pressing plate 9.

[0030] First, place the corrugated cardboard on the pressing plate 9, and then adsorb the corrugated cardboard through the adsorption assembly, so as to prevent the corrugated cardboard from shifting during flattening. After fixing, release the winding assembly. Under the action of gravity of the counterweight 23 and the support plate 6, the pulling rope 14 slides on the wire guiding wheel 4, and the support plate 6 moves downward. While moving, it slides in the slide rail 5, so that the pressing wheel 8 contacts the upper surface of the corrugated cardboard under its own gravity. Moreover, the gravity of the pressing wheel 8 pressing on the corrugated cardboard can be adjusted by increasing or decreasing the counterweight 23 in the placing groove, so as to ensure that the pressing wheel 8 does not move down too much and flatten the gaps of the corrugated cardboard. At this time, start the driving assembly. The driving assembly meshes with the rack 10, so as to drive the pressing plate 9 to move left and right through the rack 10, thereby flattening the corrugated cardboard on the pressing plate 9.

[0031] The winding assembly includes a rotating rod 11. The rotating rod 11 is rotatably connected to the cavity. A motor 12 is fixed on the workbench 2. The output shaft end of the motor 12 is fixedly connected to the rotating rod 11. A wire winding wheel 13 is fixed at the other end of the rotating rod 11. The wire winding wheel 13 is connected to the pulling rope 14.

[0032] When it is necessary to replace the flattened corrugated cardboard, start the motor 12. The motor 12 drives the rotating rod 11 to rotate. While the rotating rod 11 rotates, it drives the wire guiding wheel 4 to wind the pulling rope 14. The pulling rope 14 slides on the wire guiding wheel 4. While sliding, it pulls the support plate 6 upward, separating the pressing wheel 8 from the corrugated cardboard. Then take out the flattened corrugated cardboard, place a corrugated cardboard to be flattened, and then reverse the motor 12 to make the wire guiding wheel 4 contact the corrugated cardboard again.

[0033] The driving assembly includes a fixed seat 15 which is fixedly connected to the cavity. A second motor 16 is fixed on the fixed seat 15, and a gear 17 is fixed to the output shaft end of the second motor 16. The gear 17 meshes with a rack 10.

[0034] By starting the second motor 16, the second motor 16 drives the gear 17 to rotate. While the gear 17 rotates, it meshes with the rack 10, thereby driving the rack 10 to slide within the slideway, so that the pressing plate 9 can move back and forth, facilitating the flattening of the corrugated cardboard by the pressing wheel 8.

[0035] The adsorption assembly includes a suction fan 18 which is embedded in the pressing plate 9. A suction air pipe 19 is embedded in the pressing plate 9, and the suction air pipe 19 is fixedly connected to the suction fan 18. A number of uniformly distributed suction openings 20 are formed in the pressing plate 9, and the suction air pipe 19 is communicated with the suction openings 20.

[0036] After the corrugated cardboard is placed on the pressing plate 9, the suction fan 18 is started. The suction fan 18 adsorbs the corrugated cardboard on the pressing plate 9 through the suction air pipe 19 and the suction openings 20, preventing the problem of the position deviation of the corrugated cardboard during flattening.

[0037] Through holes are formed in both the fixing frame 3 and the slide rail, and a plug rod 21 is slidably connected within the through holes.

[0038] Inserting the plug rod 21 into the through hole can limit the position of the support plate 6, preventing the problem of the upward movement of the support plate 6 during flattening.

[0039] A limiting plate 22 is fixed to the upper end of the slide rail 5.

[0040] The limiting plate 22 fixed on the slide rail 5 can prevent the support plate 6 from moving upward too much and thus detaching from the slide rail 5.

[0041] Working principle of the utility model: First, place the corrugated cardboard on the pressing plate 9, start the suction fan 18, and the suction fan 18 adsorbs the corrugated cardboard on the pressing plate 9 through the suction pipe 19 and the suction port 20 to prevent the position of the corrugated cardboard from shifting during flattening. After fixation, start the first motor 12 to move the pressing wheel 8 to the place where it contacts the corrugated cardboard, and then start the second motor 16. The second motor 16 drives the gear 17 to rotate. While the gear 17 rotates, it meshes with the rack 10, thereby driving the rack 10 to slide in the slideway, so that the pressing plate 9 can move back and forth, facilitating the pressing wheel 8 to flatten the corrugated cardboard. When it is necessary to replace the flattened corrugated cardboard, start the first motor 12. The first motor 12 drives the rotating rod 11 to rotate. While the rotating rod 11 rotates, it drives the wire pulley 4 to wind up the pulling rope 14. The pulling rope 14 slides on the wire pulley 4 and pulls the support plate 6 upward while sliding, separating the pressing wheel 8 from the corrugated cardboard. Then take out the flattened corrugated cardboard and place a corrugated cardboard to be flattened. Then reverse the first motor 12 to make the wire pulley 4 contact the corrugated cardboard again.

[0042] In summary, through the combined use of the winding component, the driving component and the adsorption component, the function of preventing the voids of the corrugated cardboard from being flattened due to excessive force during the flattening of the corrugated cardboard is realized.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
