Description

Technical Field

[0001] This utility model belongs to the field of cardboard flattening technology, and in particular relates to a cardboard flattening device for color boxes. Background Technology

[0002] During the production of color boxes, problems such as warping and wrinkling of the cardboard can occur. This device is specifically designed to solve these problems by using mechanized methods to achieve efficient and precise leveling. Its core function is to restore the flatness of curled or deformed cardboard through uniform compression, ensuring the quality stability of subsequent processes such as die-cutting and printing.

[0003] Traditional flattening devices consist of a pressure plate, a pressure groove, and a cylinder. When operating them, workers can only place one color box cardboard at a time for flattening. They then have to wait for the flattening process to be completed and the pressure plate to rise before they can remove the flattened color box cardboard and put in a new one. This not only results in long waiting times and low work efficiency, but also poses a risk of workers being injured by the pressure plate due to accidental operation. Utility Model Content

[0004] The purpose of this invention is to provide a cardboard flattening device for color boxes. By incorporating a moving mechanism, the worker places the cardboard into two pressing slots. The pressing plate presses down on one slot to flatten the cardboard, and then lifts it up. Pulling the handle on the base plate moves the cardboard away from the pressing plate for repositioning. At this time, the other pressing slot moves under the pressing plate to perform the flattening operation. The moving pressing platform, now free from the pressing plate, allows for the replacement of the cardboard. This not only speeds up the work but also effectively prevents workers from being injured by the pressing plate due to improper operation when changing cardboard. It solves the problem that existing methods only allow workers to place one cardboard at a time for flattening, requiring them to wait for the flattening process to complete and the pressing plate to rise before removing the flattened cardboard and placing a new one. This not only results in long waiting times and low work efficiency but also poses a risk of worker injury due to improper operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cardboard flattening device for color boxes, comprising a fixed frame, an operating table fixedly connected to the top of the fixed frame, a support frame fixedly connected to the top of the operating table, and a cylinder fixedly connected to the top of the support frame, and further comprising:

[0007] A movable mechanism is located on the top of the operating table. The movable mechanism includes two movable pressing platforms. Two movable rods are fixedly connected to the top of the operating table via connecting blocks. A base plate is provided at the bottom of each movable pressing platform, and the base plate is slidably connected to the movable rods. A pressing groove is formed on the top of each movable pressing platform, and several slots are formed on the top of the base plate. Holes are formed on both sides of the base plate, through which the movable rods slide and extend to the outside. A boss corresponding to the slot on the top of the base plate is fixedly connected to the bottom of each movable pressing platform, and the boss at the bottom of the movable pressing platform engages with the slot on the top of the base plate. As the base moves back and forth on the movable rods, the two movable pressing platforms work alternately, and the cardboard flattening process is made more continuous through this alternating pressing process.

[0008] Furthermore, a plate-changing mechanism is provided at the bottom of the cylinder. The plate-changing mechanism includes a connector fixedly connected to the output end of the cylinder. The connector is hollow. A square positioning block is fixedly connected to the top of the inner wall of the connector. A fixing sleeve is threadedly connected to the outer side of the connector. A pressure plate is provided at the bottom of the fixing sleeve. A columnar locking block is fixedly connected to the center of the top of the pressure plate. The cavity of the connector is inserted into the columnar locking block. A positioning groove is opened on the top of the columnar locking block. Several fixing grooves are opened on the outer surface of the columnar locking block. The inner wall of the fixing sleeve and the outer wall of the connector are both threaded.

[0009] Furthermore, both base plates have slots at their bottoms, and the top of the work surface has a buckle. The top center of the work surface has a slot, and the buckle is placed inside the slot. The top of the buckle is curved, and a spring is installed inside the buckle. The buckle has a hollow interior, and the top of the spring is fixedly connected to the inner wall of the buckle, while the bottom of the spring is fixedly connected to the inner wall of the work surface.

[0010] Furthermore, the connector has several limiting holes inside, and annular limiting blocks are fixedly connected to the inner walls of each limiting hole. Rollers are provided inside the limiting holes, and roller grooves are provided on the surface of the rollers. Both ends of the rollers are spherical.

[0011] Furthermore, the fixed sleeve rotates clockwise to lower and lock the pressure plate, and rotates counterclockwise to raise and loosen the pressure plate. A handle is provided on the outside of the fixed sleeve for easy rotation, and a square groove is provided on the side of the movable pressure table. When the fixed sleeve moves down, the inner wall protrusion squeezes the outer spherical surface of the roller, causing it to move and the inner spherical surface to engage in the fixed groove, thereby locking the pressure plate. When replacing the movable pressure table, a tool is inserted into the square groove to pry it up. The protrusion fixedly connected to the bottom of the movable pressure table will disengage from the slot opened at the top of the base, and the movable pressure table can be removed.

[0012] Furthermore, the roller groove engages with the annular limiting block, which is used to limit the movement of the roller.

[0013] Furthermore, the cylinder is connected to an external air pipe and a solenoid valve, the protrusion on the inner wall of the fixed sleeve contacts the outer spherical surface of the roller, the inner spherical surface of the roller is adapted to the fixed groove and inserted into the fixed groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a moving mechanism, allows workers to place the color box cardboard into two pressing slots. After the cardboard is flattened and lifted by pressing down on one of the slots, the handle on the base plate is pulled to move it, allowing the pressed cardboard to leave the pressing plate for repositioning. At this time, the other pressing slot moves under the pressing plate to flatten it. The moving pressing platform, which leaves the pressing plate, can then replace the color box cardboard. This not only speeds up the work but also effectively prevents workers from being injured by the pressing plate due to improper operation when changing the color box cardboard.

[0016] 2. This utility model, by setting up a plate-changing mechanism, specifically involves rotating the fixed sleeve counterclockwise, causing the fixed sleeve to move upward, loosening the roller, and pulling the pressure plate, which can then be removed and replaced. Subsequently, a pry tool is inserted into the square groove on the side wall of the movable pressure table to pry it up, allowing the movable pressure table to be removed and replaced. This solves the cost problem of different paperboards needing different pressing devices, reduces the difficulty of inspecting and maintaining the pressure plate, and improves work efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1-7As shown, this utility model is a cardboard flattening device for color boxes, including a fixed frame 1, an operating table 13 fixedly connected to the top of the fixed frame 1, a support frame 11 fixedly connected to the top of the operating table 13, and a cylinder 12 fixedly connected to the top of the support frame 11. It also includes a moving mechanism 3, which is located on top of the operating table 13. The moving mechanism 3 includes two moving pressing platforms 32, and two moving rods 31 fixedly connected to the top of the operating table 13 via connecting blocks. A base plate 321 is provided at the bottom of the moving pressing platform 32, and the base plate 321 is slidably connected to the moving rods 31. A pressing groove 322 is opened on the top of the moving pressing platform 32, and several slots are opened on the top of the base plate 321. Holes are opened on both sides of the base plate 321. 31. The sliding plate 32 slides through the base plate 321 and extends to the outside. The bottom of the movable pressure table 32 is fixedly connected to a boss corresponding to the top slot of the base plate 321. The boss at the bottom of the movable pressure table 32 engages with the top slot of the base plate 321. The cardboard is placed into the two pressure slots 322 respectively. After the pressure plate 21 presses down on one of the pressure slots 322 to flatten the cardboard and lift it up, the handle on the base plate 321 is pulled to move it and move the pressed cardboard away from the pressure plate 21 for replacement. At this time, the other pressure slot 322 reaches below the pressure plate 21 to flatten it. The movable pressure table 32, which is away from the pressure plate 21, can replace the cardboard. This not only speeds up the work but also effectively prevents workers from being injured by the pressure plate due to improper operation when changing cardboard.

[0030] A plate-changing mechanism 2 is provided at the bottom of the cylinder 12. The plate-changing mechanism 2 includes a connector 23 fixedly connected to the output end of the cylinder 12. The connector 23 is hollow. A square positioning block 231 is fixedly connected to the top of the inner wall of the connector 23. A fixing sleeve 22 is threadedly connected to the outer side of the connector 23. A pressure plate 21 is provided at the bottom of the fixing sleeve 22. A columnar locking block 213 is fixedly connected to the center of the top of the pressure plate 21. The cavity of the connector 23 is inserted into the columnar locking block 213. A positioning groove 212 is opened on the top of the columnar locking block. The outer surface of 213 has several fixing grooves 211; the inner wall of the fixing sleeve 22 and the outer wall of the connector 23 are both threaded; rotating the fixing sleeve 22 counterclockwise moves the fixing sleeve 22 upward, loosens the roller 24, and pulls the pressure plate 21, so that the pressure plate 21 can be removed and replaced. Then, a pry tool is used to insert into the square groove on the side wall of the movable pressure table 32 to pry it up, so that the movable pressure table 32 can be removed and replaced. This solves the cost problem of different paperboards needing to be equipped with different flattening devices, and also reduces the difficulty of inspecting and maintaining the pressure plate, thus improving work efficiency.

[0031] Both base plates 321 have slots 325 at their bottoms, and the top of the work surface 13 has a buckle 324. The top center of the work surface 13 has a slot, and the buckle 324 is placed in the slot. The top of the buckle 324 is curved, and a spring 323 is installed inside the buckle 324. The buckle 324 has a hollow cavity. The top of the spring 323 is fixedly connected to the inner wall of the buckle 324, and the bottom of the spring 323 is fixedly connected to the inner wall of the work surface 13.

[0032] The connector 23 has several limiting holes 232 inside, and annular limiting blocks 233 are fixedly connected to the inner walls of the limiting holes 232. Rollers 24 are provided inside the limiting holes 232, and roller grooves 241 are provided on the surface of the rollers 24. Both ends of the rollers 24 are spherical.

[0033] The fixed sleeve 22 rotates clockwise to move down and lock the pressure plate 21, and rotates counterclockwise to move up and release the pressure plate 21. A handle is provided on the outside of the fixed sleeve 22 to facilitate rotation, and a square groove is provided on the side of the movable pressure table 32.

[0034] The roller groove 241 engages with the annular limit block 233, which is used to limit the movement of the roller 24.

[0035] The cylinder 12 is connected to an external air pipe and a solenoid valve. The protrusion on the inner wall of the fixed sleeve 22 contacts the outer spherical surface of the roller 24. The inner spherical surface of the roller 24 is adapted to the fixed groove 211 and inserted into the fixed groove 211.

[0036] One specific application of this embodiment is:

[0037] In use, the worker places the cardboard boxes to be flattened into the pressing slots 322 of the two movable pressing tables 32, activates the cylinder 12, and the output end of the cylinder 12 drives the pressing plate 21 to move downward. At this time, the pressing plate 21 cooperates with the movable pressing table 32 to flatten the cardboard boxes. Then, the output end of the cylinder 12 drives the pressing plate 21 to move upward. After the pressing plate 21 leaves the pressing slot 322, the worker pulls the handle on the bottom plate 321 connected to the bottom of the movable pressing table 32. The bottom plate 321 moves on the moving rod 31. Because the top of the buckle 324 is spherical, as the bottom plate 321 moves, the buckle 324 slides out from the slot 325 at the bottom of the bottom plate 321. The spring 323 inside the buckle 324 is compressed and in a contracted state. When the base plate 321 moves to the corresponding slot 325 at the bottom of the base plate 321, the pressure disappears and the spring 323 returns to its original state, causing the buckle 324 to spring into the slot 325. At this time, the other slot 322 is under the pressure plate 21, and the flattening operation can be performed again. At this time, the color box cardboard on the other movable pressure table 32 can be taken out and replaced with a new color box cardboard, so that the color box cardboard is in a pre-processed state. This realizes the alternating operation of the two movable pressure tables 32. Through the alternating flattening process, the flattening operation of the color box cardboard is made more continuous.

[0038] When workers need to flatten color box cardboard of different sizes, they need to change the pressure plate 21 and the movable pressure table 32 of different sizes. When changing the pressure plate 21, rotate the fixed sleeve 22 counterclockwise to move the fixed sleeve 22 upward, the pressure of the pressing roller 24 will be released, and the pressure plate 21 will be pulled downward. The side wall of the fixed groove 211 will squeeze the roller 24, causing it to move out of the fixed groove 211, and the pressure plate 21 can be removed. When installing the new pressure plate 21, align the positioning groove 212 at the top of the pressure plate 21 with the square positioning block 231 and insert it to avoid the pressure plate 21 being crooked. Then rotate the fixed sleeve 22 clockwise to move it downward. At this time, the inner wall of the fixed sleeve 22 will squeeze the roller 24, and the roller 231 will move downward. 4. Move the pressure plate 21 into the fixing groove 211 of the new pressure plate 21 in the limiting hole 232 and lock the pressure plate 21 to complete the replacement of the pressure plate 21. When replacing the movable pressure table 32, use a pry tool to insert into the groove on the side wall of the movable pressure table 32, pry up one end and pull the movable pressure table 32 upward to disengage the several fixedly connected protrusions at the bottom of the movable pressure table 32 from the groove on the base plate 321, and then remove the movable pressure table 32. When installing the new movable pressure table 32, align the several fixedly connected protrusions at the bottom of the new movable pressure table 32 with the groove on the top of the base plate 321 and insert and press it to complete the replacement of the movable pressure table 32.

[0039] It should be noted that the control of cylinder 12 in this application adopts a program set in the control panel, and the relevant parameters are input according to the requirements for automatic control. The setting of this control method can be achieved by existing technologies, such as PLC.
