Description

Technical Field

[0001] This utility model belongs to the field of cardboard box manufacturing technology, and specifically relates to a cardboard flattening device for cardboard box manufacturing. Background Technology

[0002] The most common use of cardboard boxes is for storing goods, facilitating their handling and transfer. Their application is particularly prevalent in the logistics industry. A search reveals application number "CN202221107493.5," which describes a method where "a drive motor rotates, causing a transmission rod to rotate, which in turn rotates a second and third conical wheel simultaneously. Because the second and third conical wheels have opposite tooth directions, they cause the first conical wheel to rotate relative to it, thereby causing the upper and lower pressure rollers to rotate relative to each other, achieving a pressing function to flatten the surface and avoiding the poor flattening effect of directly using a pressure plate." While this method of using a drive motor to rotate a transmission rod, which in turn rotates the second and third conical wheels simultaneously, and because the second and third conical wheels have opposite tooth directions, causing the first conical wheel to rotate relative to it, and thus causing the upper and lower pressure rollers to rotate relative to each other, does indeed achieve a pressing function to flatten the surface and avoid the poor flattening effect of directly using a pressure plate, the above-mentioned application has the following problems in actual use:

[0003] In actual use, the downward pressure cannot be adjusted, resulting in unstable downward pressure. Furthermore, feeding is troublesome, leading to poor efficiency.

[0004] Therefore, providing a device that can adjust the downward pressure and facilitate feeding is highly practical. Utility Model Content

[0007] The top of the protective box is provided with several first electric cylinders, and the output shaft ends of the several first electric cylinders all penetrate through the top of the inner wall of the protective box.

[0008] The stabilizing and flattening pressure regulating assembly includes a support plate disposed at the bottom of the output shafts of two first electric cylinders. Two fixed rods are disposed at the bottom of the support plate, and each fixed rod has a limit plate at its bottom. A fixed plate is slidably connected to the outer bottom wall of the two fixed rods. Two springs are disposed at the top of the fixed plate, and the interiors of the two springs are slidably connected to the fixed rods. A second electric cylinder is disposed at the top of the support plate. A pressure regulating plate is disposed through the output shaft end of the second electric cylinder, and the interior of the pressure regulating plate is slidably connected to the two fixed rods. The bottom of the pressure regulating plate is fixedly connected to the two springs. Several auxiliary plates are disposed at the bottom of the fixed plate, and a pressure roller is rotatably connected to the middle of the auxiliary plates. A lower pressure device is disposed at the bottom of the output shafts of the other two first electric cylinders.

[0009] The stable and rapid feeding assembly includes feeding ports on both sides of the protective box. One side of one of the feeding ports is sealed and connected to a connecting frame, and the other side of the connecting frame is sealed and connected to a feeding box. A reinforcing rod is provided on one side of the feeding box, and one side of the reinforcing rod is fixedly connected to the protective box. A third electric cylinder is provided on one side of the feeding box. The output shaft end of the third electric cylinder passes through one side of the feeding box and is provided with a pusher plate. Two limit rods are slidably connected to the top of the pusher plate. One end of each of the two limit rods is fixedly connected to one end of the inner wall of the protective box. Two rotating rods are provided on the inner wall of the protective box. A conveyor belt is externally connected to the two rotating rods. A torque motor is provided at one end of the protective box. The output shaft end of the torque motor passes through one end of the inner wall of the protective box and is rotatably connected to one of the rotating rods.

[0010] In one embodiment of this utility model, a support platform is movably connected to the middle of the conveyor belt, and both ends of the support platform are fixedly connected to the inner wall of the protective box.

[0011] In one embodiment of this utility model, guide plates are provided on both sides of the inner wall of the protective box.

[0012] In one embodiment of this utility model, the outer wall of the conveyor belt is provided with two isolation belts.

[0013] In one embodiment of this utility model, the bottom of the protective box is provided with two support legs, and the bottom of each of the two support legs is provided with an anti-slip pad.

[0014] In one embodiment of this utility model, the protective box is made of chromium metal, and a microcontroller is provided at the top corner of the protective box.

[0015] In one embodiment of this utility model, the first electric cylinder, the second electric cylinder, the third electric cylinder, and the torque motor are all electrically connected to a microcontroller, and the microcontroller is electrically connected to an external power supply.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The provided support plate allows the user to easily activate the first electric cylinder via a microcontroller. This first electric cylinder moves the support plate downwards, which in turn moves its bottom components downwards to adjust the distance between the pressure roller and the conveyor belt. This accommodates cartons of varying thicknesses. During use, the cartons are transported to the bottom of the pressure roller via the conveyor belt. The pressure roller then transmits force to the auxiliary plate, causing the spring to contract and store energy, resulting in a rebound force that initially compresses the cartons. The user needs to adjust the downward pressure by activating the second electric cylinder via the microcontroller. The first cylinder drives the second electric cylinder to move the pressure plate downwards, which in turn compresses the spring, causing it to contract. This allows for increased downward pressure during subsequent rebound, and decreased pressure during rebound, thus adjusting the downward pressure. It is important to note that "both the pressure roller and the conveyor belt are equipped with anti-slip textures to prevent the carton from sliding." After the pressure roller initially presses down, the conveyor belt transports the carton to the pressure device. At this point, the user uses two other first electric cylinders to drive the pressure device to apply a second pressure to the carton, thereby achieving stable flattening and allowing for adjustment of the downward pressure.

[0018] 2) The feeding box allows users to easily place multiple flat cartons into it. The microcontroller activates the third electric cylinder, which drives the pusher plate to push the cartons through the feed inlet and onto the conveyor belt. At this point, the user activates the torque motor via the microcontroller, which drives the rotating rod to rotate, causing the conveyor belt to run and transport the cartons, thus achieving rapid feeding. It should be noted that the pusher plate only needs to push the edges of the cartons onto the conveyor belt, and then retracts using the third electric cylinder, waiting for the next carton to fall before pushing it again.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figure 1-4 A cardboard flattening device for carton manufacturing includes a protective box 100, a stable flattening and adjusting pressure component 200, and a stable and rapid feeding component 300.

[0028] Please refer to the details. Figure 1 The top of the protective box 100 is provided with several first electric cylinders 110, and the output shaft ends of the several first electric cylinders 110 all penetrate through the top of the inner wall of the protective box 100.

[0029] Please see Figure 3-4The stabilizing and flattening pressure regulating assembly 200 includes a support plate 210 disposed at the bottom of the output shafts of two first electric cylinders 110. Two fixing rods 220 are disposed at the bottom of the support plate 210, and each fixing rod 220 has a limit plate at its bottom. A fixing plate 230 is slidably connected to the outer wall of the bottom of the two fixing rods 220. Two springs 240 are disposed at the top of the fixing plate 230, and the interior of each spring 240 is slidably connected to the fixing rod 220. A second electric cylinder 250 is disposed at the top of the support plate 210. A pressure regulating plate 260 is disposed through the support plate 210 at the end of the output shaft of the second electric cylinder 250. The interior of the pressure regulating plate 260 is slidably connected to the two fixing rods 220, and the bottom of the pressure regulating plate 260 is fixedly connected to the two springs 240. Several auxiliary plates 270 are disposed at the bottom of the fixing plate 230, and a pressure roller 280 is rotatably connected to the middle of the auxiliary plates 270. A lowering device 290 is disposed at the bottom of the output shafts of the other two first electric cylinders 110.

[0030] In one specific embodiment, a support plate 210 allows the user to easily activate the first electric cylinder 110 via a microcontroller. This cylinder moves the support plate 210 downwards, causing its bottom components to adjust the distance between the pressure roller 280 and the conveyor belt 370 to accommodate cartons of varying thicknesses. During use, the cartons are transported to the bottom of the pressure roller 280 via the conveyor belt 370. The pressure roller 280 then transmits force to the auxiliary plate 270, causing the spring 240 to contract and store energy, resulting in a rebound force that initially compresses the cartons. The user can adjust the pressure level via a microcontroller. Opening the second electric cylinder 250 causes it to move the pressure adjusting plate 260 downwards, which in turn compresses the spring 240, causing it to contract. This allows for increased downward pressure during subsequent rebound, and decreased pressure during subsequent rebound, thus adjusting the downward pressure. It should be noted that "both the pressure roller 280 and the conveyor belt 370 are equipped with anti-slip textures to prevent the carton from sliding." After the pressure roller 280 initially presses down, the conveyor belt 370 transports the carton to the pressure reducer 290. At this point, the user uses the other two first electric cylinders 110 to drive the pressure reducer 290 to apply a second downward pressure to the carton, thereby achieving stable flattening and adjusting the downward pressure.

[0031] Please see Figure 1-3The stable and rapid feeding component 300 includes feeding ports on both sides of the protective box 100. One side of one feeding port is sealed to a connecting frame 310, and the other side of the connecting frame 310 is sealed to a feeding box 320. A reinforcing rod is provided on one side of the feeding box 320, and one side of the reinforcing rod is fixedly connected to the protective box 100. A third electric cylinder 330 is provided on one side of the feeding box 320, and the output shaft end of the third electric cylinder 330 passes through one side of the feeding box 320 and is provided with a pusher. The top of the pusher plate 340 is slidably connected to two limiting rods 350. One end of each limiting rod 350 is fixedly connected to one end of the inner wall of the protective box 100. The inner wall of the protective box 100 is provided with two rotating rods 360. The two rotating rods 360 are externally connected to a conveyor belt 370. One end of the protective box 100 is provided with a torque motor 380. The output shaft end of the torque motor 380 passes through one end of the inner wall of the protective box 100 and is rotatably connected to one of the rotating rods 360.

[0032] In one specific embodiment, the feeding box 320 allows users to easily place multiple flat cartons into it. A microcontroller activates a third electric cylinder 330, which drives a pusher plate 340 to push the cartons through the inlet and guide plate 500 onto the conveyor belt 370. The user then activates a torque motor 380 via the microcontroller, causing the rotating rod 360 to rotate, which in turn drives the conveyor belt 370, transporting the cartons and achieving rapid feeding. It should be noted that the pusher plate 340 only needs to push the edges of the cartons onto the conveyor belt 370, and then retracts using the third electric cylinder 330, waiting for the next carton to fall before pushing it again.

[0033] Please see Figure 3 A support platform 400 is movably connected to the middle of the conveyor belt 370, and both ends of the support platform 400 are fixedly connected to the inner wall of the protective box 100.

[0034] In one specific embodiment, the provided support platform 400 facilitates the pressing function by effectively supporting the carton across the conveyor belt 370, thereby improving work efficiency.

[0035] Please see Figure 3 Guide plates 500 are provided on both sides of the inner wall of the protective box 100.

[0036] In one specific embodiment, the guide plate 500 is provided to facilitate the rapid movement of the carton during material feeding and unloading.

[0037] Please see Figure 3 The outer wall of the conveyor belt 370 is equipped with two isolation belts 600.

[0038] In one specific embodiment, the isolation belt 600 allows the conveyor belt 370 to limit the carton when transporting it, preventing it from shifting and improving stability.

[0039] Please see Figure 3 The bottom of the protective box 100 is provided with two support legs 700, and the bottom of both support legs 700 is provided with anti-slip pads.

[0040] In one specific embodiment, the provided support leg 700 facilitates the support and fixation of the top part, making it more stable during use, avoiding wobbling and improving stability.

[0041] Please see Figure 3 The protective box 100 is made of chromium metal, and a microcontroller is installed at the top corner of the protective box 100.

[0042] In one specific embodiment, the presence of chromium metal allows the protective box 100 to be used more stably due to its robust and durable properties, thus preventing shaking during use.

[0043] Please see Figure 1-4 The first electric cylinder 110, the second electric cylinder 250, the third electric cylinder 330 and the torque motor 380 are all electrically connected to the microcontroller, which is electrically connected to an external power supply.

[0044] In one specific embodiment, the included microcontroller facilitates power control of the electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0045] In use, the support plate 210 allows the user to easily activate the first electric cylinder 110 via a microcontroller. The first electric cylinder 110 moves the support plate 210 downwards, which in turn moves its bottom components downwards to adjust the distance between the pressure roller 280 and the conveyor belt 370, accommodating cartons of different thicknesses. During use, the cartons are transported to the bottom of the pressure roller 280 via the conveyor belt 370. At this point, the pressure roller 280 receives force and transmits it to the auxiliary plate 270, which in turn causes the spring 240 to retract. The compression and subsequent rebound force achieve the initial squeezing of the cardboard box. During use, the downward pressure needs to be adjusted. The operator activates the second electric cylinder 250 via a microcontroller, causing the pressure adjusting plate 260 to move downwards. This compresses the spring 240, causing it to contract. This contraction allows for increased downward pressure during the subsequent rebound, and vice versa, thus adjusting the downward pressure. It is important to note that both the pressure roller 280 and the conveyor belt 370 have anti-slip textures on their exteriors to prevent paper from slipping. "The carton is slipping." After the pressure roller 280 initially presses down, the conveyor belt 370 transports the carton to the presser 290. At this time, the user uses two other first electric cylinders 110 to drive the presser 290 downward to squeeze the carton a second time, thereby achieving stable flattening and allowing adjustment of the downward pressure. Then, through the provided feeding box 320, the user can easily place multiple flat cartons into the feeding box 320, and the microcontroller opens the third electric cylinder 330, causing the third electric cylinder 330 to drive... The pusher plate 340 pushes the carton through the feed inlet and guide plate 500 onto the conveyor belt 370. At this time, the user turns on the torque motor 380 through the microcontroller, which drives the rotating rod 360 to rotate. Finally, the conveyor belt 370 runs, carrying the carton and thus achieving the purpose of rapid feeding. It should be noted that the pusher plate 340 only needs to push the edge of the carton onto the conveyor belt 370. The third electric cylinder 330 is used to retract it, and it waits for the next carton to fall before pushing it again.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
