Description

Technical Field

[0001] This utility model relates to the field of flattening devices, specifically a flattening device for paper box production. Background Technology

[0002] With the rapid development of modern industry and the continuous improvement of people's living standards, the demand for packaging boxes is constantly increasing and ubiquitous. Moreover, higher requirements are being placed on the convenience of product packaging boxes. During the processing of paper boxes, it is often necessary to flatten the paper boxes to improve the flatness of the cardboard and avoid problems such as poor paper feeding, uneven adsorption, and poor printing effect caused by the bending of the paper boxes.

[0003] A search revealed that Chinese utility model patent CN222769080U discloses a flattening device for paper box production, including a processing table. Support plates are provided at both ends of the top surface of the processing table, and the support plates are fixedly connected to the top plate. A flattening mechanism and two fixing mechanisms are provided above the processing table, with the fixing mechanisms located on both sides of the flattening mechanism. A motor is fixedly installed on the bottom surface of the top plate, with the motor's drive shaft coaxially fixed to a screw. The screw passes through a sliding plate and is threadedly connected to the sliding plate. Two connecting columns are provided on both sides of the sliding plate. The flattening mechanism is located below the bottom surface of the sliding plate. First, the fixing mechanisms fix the edges of the paper box to prevent displacement during the flattening process. Then, the motor drives the screw to rotate, causing the sliding plate to move and carrying the flattening roller to flatten the entire paper box. When the flattening roller moves to the edge of the paper box, the connecting columns contact the fixing mechanisms and cause the fixing mechanisms to move away from the paper box, allowing the flattening roller to flatten the edge of the paper box.

[0004] The technical solution in the application still has shortcomings: it requires staff to manually place and remove the cardboard, which is cumbersome, increases the intensity of manual labor, affects the production efficiency of the cardboard box, and the cardboard is prone to shifting during the flattening process, thus affecting the flattening effect. Summary of the Invention

[0005] The purpose of this invention is to provide a flattening device for paper box production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flattening device for paper box production, comprising a frame, an upper flattening roller, a placement platform, a base, and a lower flattening roller. A side plate is mounted on the base, and a placement platform is mounted on the side plate. A frame is mounted on the base, and an electric telescopic rod B is mounted on the frame. An mounting plate is mounted at one end of the electric telescopic rod B, and a drive roller is mounted on the mounting plate. An electric telescopic rod A is mounted on the frame, and a spring column is mounted at one end of the electric telescopic rod A. An mounting frame is mounted at one end of the spring column, and an upper flattening roller is mounted on the mounting frame. A limit ring and a fixing ring are fitted onto the upper flattening roller, and the limit ring and the fixing ring are integrally connected. A fixing screw is threaded onto the fixing ring, and a lower flattening roller is mounted on the base.

[0007] Using the above technical solution, the electric telescopic rod B installed on the starting frame extends, driving the drive roller installed on the mounting plate to move downwards. After the drive roller moves to the appropriate position, the drive motor starts to rotate the drive roller. At this time, the motor A installed in the side plate starts, driving the lead screw to rotate, causing the ball nut threaded on the lead screw to move upwards, thereby driving the placement platform to move upwards. When the topmost piece of cardboard moves upwards to contact the drive roller, the drive roller will drive the cardboard forward, conveying the cardboard between the upper and lower flattening rollers. The upper and lower flattening rollers flatten the cardboard. The flattened cardboard moves onto the conveyor belt for conveying to the next process. A sensor is installed above the conveyor belt in the frame. When the flattened cardboard moves to the designated position, the sensor sends a signal to the control system. The control system controls motor A to start, causing the placement platform to move upwards to move the next piece of cardboard to contact the drive roller, and perform the next round of cardboard feeding and flattening operations. The system requires manual placement and removal of cardboard, reducing labor intensity and increasing cardboard box production efficiency. The electric telescopic rod A on the frame moves the upper and lower pressure rollers up and down, adjusting the distance between them to accommodate cardboard of different thicknesses, thus improving the equipment's versatility and practicality. During the pressing process, the spring posts effectively buffer the impact, preventing damage to the cardboard from excessive pressure. Simultaneously, the limiting and fixing rings on the upper and lower pressure rollers prevent cardboard from shifting during pressing, ensuring optimal pressing results. After moving the limiting ring to the appropriate position, rotating the fixing screw on the fixing ring causes one end of the screw to abut against the outer wall of the pressing roller, thus fixing the limiting ring. Adjusting the distance between the two sets of limiting rings accommodates cardboard of different sizes, further enhancing the equipment's versatility and practicality.

[0008] Preferably, a motor A is installed in the side plate, a lead screw is installed at the power shaft end of the motor A, a ball nut is threaded onto the lead screw, and the ball nut is connected to the placement platform.

[0009] By using the above technical solution, the motor A installed in the side plate is started, which drives the lead screw to rotate, causing the ball nut threaded on the lead screw to move upward, thereby moving the stacked cardboard on the placement table upward. When the top cardboard moves up to contact the drive roller, the drive roller will move the cardboard forward for feeding. There is no need to manually place the cardboard sheets one by one between the upper and lower pressing rollers, which greatly saves manpower and improves the pressing efficiency.

[0010] Preferably, a conveyor roller is mounted on the frame, a conveyor belt is installed between the conveyor rollers, and the power shaft of motor B mounted on the frame is connected to the conveyor roller.

[0011] Using the above technical solution, motor B starts and drives the conveyor roller to rotate, thereby driving the conveyor belt to operate. The flattened cardboard moves onto the conveyor belt. As the conveyor belt moves, the cardboard is continuously and stably transported to the next process for processing. There is no need for workers to manually remove the flattened cardboard, which further reduces the intensity of manual labor and provides convenience for subsequent processing operations.

[0012] Preferably, a motor C is mounted on the mounting frame, the power shaft end of the motor C is connected to the upper pressure roller, and the drive motor on the mounting plate is connected to the drive roller.

[0013] Using the above technical solution, by starting the motor C installed on the mounting frame, the flattening roller rotates to cooperate with the lower flattening roller to flatten the cardboard. The drive motor on the mounting plate starts and drives the drive roller to rotate, conveying the cardboard in contact with it between the upper and lower flattening rollers, so that the cardboard can be smoothly and continuously conveyed to the flattening area.

[0014] Preferably, two sets of limiting rings are provided, the diameter of the limiting rings is larger than the diameter of the upper pressing roller, and a fixing block is provided at one end of the fixing screw.

[0015] By adopting the above technical solution, the diameter of the limiting ring is larger than the diameter of the upper pressing roller, which allows the limiting ring to better constrain the cardboard and prevent the cardboard from slipping off both sides of the pressing roller during the pressing process, thus further improving the pressing effect. The fixing block set at one end of the fixing screw increases the friction between the fixing screw and the outer wall of the pressing roller, so that the limiting ring can be stably fixed after the position is adjusted, preventing displacement during the pressing process and ensuring the stability and accuracy of the pressing operation.

[0016] Preferably, the lower pressure roller has the same structure as the upper pressure roller.

[0017] Using the above technical solution, the lower pressure roller and the upper pressure roller have the same function and characteristics. The two work together to complete the flattening operation of the paperboard, ensuring the consistency and quality of the paperboard flattening.

[0018] Compared with the prior art, the beneficial effects of this utility model are: By starting motor A, the lead screw rotates, causing the ball bearing nut threaded on the lead screw to move upward, thereby moving the placement platform upward. When the top piece of cardboard moves up and contacts the drive roller, the drive roller rotates, moving the cardboard forward and conveying it between the upper and lower flattening rollers. The upper and lower flattening rollers flatten the cardboard. The flattened cardboard moves onto the conveyor belt and is conveyed to the next process. A sensor is installed above the conveyor belt in the frame. When the flattened cardboard moves to the designated position, the sensor sends a signal to the control system. The control system then starts motor A, causing the placement platform to move upward and move the next piece of cardboard to contact the drive roller, starting the next round of cardboard feeding and flattening operations. This eliminates the need for manual placement and removal of cardboard, reducing labor intensity and improving the production efficiency of cardboard boxes.

[0019] The electric telescopic rod A on the frame can drive the upper pressure roller to move up and down, adjusting the distance between the upper and lower pressure rollers to adapt to the flattening needs of cardboard of different thicknesses, thus improving the versatility and practicality of the equipment. During the flattening process, the spring column can effectively buffer the impact force during the flattening process, preventing the cardboard from being damaged by excessive pressure.

[0020] The limiting rings and fixing rings on the upper and lower pressing rollers constrain the cardboard and prevent it from slipping off the sides of the pressing rollers, thus avoiding deviation during the pressing process and ensuring the pressing effect. After moving the limiting ring to the appropriate position, the fixing screw on the fixing ring is rotated so that the fixing block at one end of the fixing screw abuts against the outer wall of the pressing roller, thereby fixing the limiting ring. By adjusting the distance between the two sets of limiting rings, the pressing needs of cardboard of different sizes can be adapted, further improving the versatility and practicality of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-4This utility model provides an embodiment of a flattening device for paper box production, comprising a frame 1, an upper flattening roller 5, a placement platform 14, a base 15, and a lower flattening roller 16. A side plate 11 is mounted on the base 15, and the placement platform 14 is mounted on the side plate 11. The frame 1 is mounted on the base 15, and an electric telescopic rod B9 is mounted on the frame 1. An mounting plate 10 is mounted at one end of the electric telescopic rod B9, and a drive roller 21 is mounted on the mounting plate 10. An electric telescopic rod A2 is mounted on the frame 1, and a spring column 3 is mounted at one end of the electric telescopic rod A2. An mounting frame 4 is mounted at one end of the spring column 3, and the upper flattening roller 5 is mounted on the mounting frame 4. A limiting ring 6 and a fixing ring 7 are fitted onto the upper flattening roller 5, and the limiting ring 6 and the fixing ring 7 are integrally connected. A fixing screw 8 is threaded onto the fixing ring 7. The lower flattening roller 16 is mounted on the base 15. The electric telescopic rod B9 installed on the starting frame 1 extends, driving the drive roller 21 installed on the mounting plate 10 to move downwards. After the drive roller 21 moves to the appropriate position, the drive motor starts to rotate the drive roller 21. At this time, the motor A12 installed in the side plate 11 starts, driving the lead screw 13 to rotate, causing the ball nut 22 threaded on the lead screw 13 to move upwards, thereby driving the placement table 14 to move upwards. When the topmost piece of cardboard moves upwards and contacts the drive roller 21, the drive roller 21 will drive the cardboard forward, conveying the cardboard between the upper flattening roller 5 and the lower flattening roller 16. The upper flattening roller 5 and the lower flattening roller 16 flatten the cardboard. The flattened cardboard moves to the conveyor belt 18 and is conveyed to the next process. A sensor is installed above the conveyor belt in the frame 1. When the flattened cardboard moves to the designated position, the sensor will send a signal to the control system. The control system controls the motor A12 to start, causing the placement table 14 to move upwards and move the next piece of cardboard to contact the drive roller 21, starting the next round of cardboard feeding. The flattening operation eliminates the need for manual placement and removal of cardboard, reducing labor intensity and improving cardboard production efficiency. The electric telescopic rod A2 on frame 1 can move the upper flattening roller 5 up and down, adjusting the distance between the upper flattening roller 5 and the lower flattening roller 16 to accommodate flattening needs of cardboard of different thicknesses, thus improving the equipment's versatility and practicality. During the flattening process, the spring column 3 effectively buffers the impact force, preventing the cardboard from being damaged by excessive pressure. At the same time, the limiting ring 6 and fixing ring 7 on the upper flattening roller 5 and the lower flattening roller 16 prevent the cardboard from shifting during the flattening process, ensuring the flattening effect. After moving the limiting ring 6 to the appropriate position, the fixing screw 8 on the fixing ring 7 is rotated so that one end of the fixing screw 8 abuts against the outer wall of the flattening roller, thereby fixing the limiting ring 6. By adjusting the distance between the two sets of limiting rings 6, the flattening needs of cardboard of different sizes can be accommodated, further improving the equipment's versatility and practicality.

[0025] A motor A12 is installed in the side plate 11, and a lead screw 13 is installed at the power shaft end of the motor A12. A ball nut 22 is threaded onto the lead screw 13, and the ball nut 22 is connected to the placement table 14. By starting the motor A12 installed in the side plate 11, the lead screw 13 is driven to rotate, causing the ball nut 22 threaded onto the lead screw 13 to move upward, thereby moving the stacked cardboard on the placement table 14 upward. When the top cardboard moves up to contact the drive roller 21, the drive roller 21 will move the cardboard forward for feeding. There is no need to manually place the cardboard sheets one by one between the upper flattening roller 5 and the lower flattening roller 16, which greatly saves manpower and improves flattening efficiency.

[0026] A conveyor roller 17 is mounted on the frame 1, and a conveyor belt 18 is installed between the conveyor rollers 17. The power shaft of a motor B20 mounted on the frame 1 is connected to the conveyor rollers 17. When the motor B20 starts, it drives the conveyor rollers 17 to rotate, thereby driving the conveyor belt 18 to operate. The flattened cardboard moves onto the conveyor belt 18. As the conveyor belt 18 moves, the cardboard is continuously and stably transported to the next process for processing. There is no need for workers to manually remove the flattened cardboard, which further reduces the intensity of manual labor and provides convenience for subsequent processing operations.

[0027] A motor C19 is mounted on the mounting frame 4, and the power shaft of the motor C19 is connected to the upper pressure roller 5. A drive motor on the mounting plate 10 is connected to the drive roller 21. By starting the motor C19 mounted on the mounting frame 4, the pressure roller 5 rotates to cooperate with the lower pressure roller 16 to flatten the cardboard. The drive motor on the mounting plate 10 starts, driving the drive roller 21 to rotate, conveying the cardboard in contact with it between the upper pressure roller 5 and the lower pressure roller 16, so that the cardboard can be smoothly and continuously conveyed to the flattening area.

[0028] Two sets of limiting rings 6 are provided. The diameter of the limiting rings 6 is larger than the diameter of the upper flattening roller 5. A fixing block is provided at one end of the fixing screw 8. The larger diameter of the limiting rings 6 allows them to better constrain the cardboard, preventing it from slipping off the sides of the flattening roller during the flattening process, thus further improving the flattening effect. The fixing block at one end of the fixing screw 8 increases the friction between the fixing screw 8 and the outer wall of the flattening roller, ensuring that the limiting rings 6 can be stably fixed after adjustment, preventing displacement during the flattening process and guaranteeing the stability and accuracy of the flattening operation.

[0029] The lower flat roller 16 has the same structure as the upper flat roller 5. The lower flat roller 16 and the upper flat roller 5 have the same function and characteristics. They work together to complete the flattening operation of the paperboard, ensuring the consistency and quality of the paperboard flattening.

[0030] The control system and electronic components involved in this application are all existing mature technologies, with many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional use. The scope of protection of this application does not involve improvements to the control system and electronic components, so the models of electronic components and the control flow of the control system will not be described in detail here. The motor equipment in this application is equipped with a circuit controller and a brake mechanism. The circuit controller allows the motor to flexibly adjust the rotation direction and rotation angle according to actual operating requirements, significantly improving the operational flexibility and safety performance of the equipment. The brake mechanism reliably locks the position when the motor stops, preventing accidental displacement caused by inertia and ensuring the stability and safety of the device in the stopped state.

[0031] Working principle: Workers use a forklift or other transport vehicle to move stacked cardboard onto the placement platform 14. Then, the electric telescopic rod B9 installed on the frame 1 extends, causing the drive roller 21 installed on the mounting plate 10 to move downwards. After the drive roller 21 moves to the appropriate position, the drive motor starts, causing the drive roller 21 to rotate. At this time, the motor A12 installed in the side plate 11 starts, driving the lead screw 13 to rotate, causing the ball nut 22 threaded on the lead screw 13 to move upwards, thereby moving the placement platform 14 upwards. When the topmost cardboard moves to the appropriate position... When the drive roller 21 contacts, it moves the cardboard forward, conveying it between the upper flattening roller 5 and the lower flattening roller 16. The upper and lower flattening rollers flatten the cardboard, and the flattened cardboard moves onto the conveyor belt 18 for transport to the next process. A sensor is installed above the conveyor belt in the frame 1. When the flattened cardboard moves to a designated position, the sensor sends a signal to the control system. The control system then starts the motor A12, causing the placement table 14 to move upwards to position the next piece of cardboard. The drive roller 21 contacts the cardboard to begin the next round of feeding and flattening operations. This eliminates the need for manual placement and removal of cardboard, reducing labor intensity and increasing production efficiency. The electric telescopic rod A2 on frame 1 moves the upper flattening roller 5 up and down, adjusting the distance between it and the lower flattening roller 16 to accommodate flattening requirements of cardboard of different thicknesses, thus improving the equipment's versatility and practicality. During flattening, the spring column 3 effectively buffers the impact force, preventing damage to the cardboard due to excessive pressure. Simultaneously, the limiting rings 6 and fixing rings 7 on the upper and lower flattening rollers 5 and 16 prevent cardboard from shifting during flattening, ensuring optimal flattening results. After moving the limiting ring 6 to the appropriate position, the fixing screw 8 on the fixing ring 7 is rotated, causing one end of the fixing screw 8 to abut against the outer wall of the flattening roller, thereby fixing the limiting ring 6. By adjusting the distance between the two sets of limiting rings 6, the equipment can accommodate flattening requirements of different cardboard sizes, further enhancing its versatility and practicality.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
