Description

Technical Field

[0001] This utility model relates to a cardboard processing equipment, specifically an integrated machine that combines cardboard slitting and cardboard stacking functions. Background Technology

[0002] A cardboard slitting machine is a device used to cut cardboard. Large cardboard pieces are cut into smaller pieces, which then need to be stacked. For example... Figure 5 As shown, these small cardboard pieces are conveyed forward in a fish-scale stack by a conveyor frame to the receiving position, where they are collected manually. The large quantity of slit cardboard necessitates significant manpower for collection, leveling, and stacking; often, one slitting machine requires two to three people to effectively collect and stack the cardboard, increasing labor costs. Furthermore, since slitting machines already occupy a large amount of production space, some factories, limited by space, need to add a small cardboard collection, stacking, and palletizing machine to reduce the collection work from three people to one. Currently, there are also integrated machines on the market that can stack cardboard after slitting. For example, CN117301184A discloses a cardboard cutting and stacking device. This device includes a longitudinal cutting mechanism, a transverse cutting mechanism, and a cardboard stacking mechanism. After being cut by the longitudinal and transverse cutting mechanisms, the cardboard enters the cardboard stacking mechanism for stacking. This cardboard stacking mechanism stacks the cardboard by rotating multiple receiving plates, thus achieving non-stop stacking. However, this type of cardboard stacking mechanism has significant limitations: First, due to the structural limitations of the receiving plate, the number of cards stacked each time is greatly limited; second, this receiving plate cannot meet the stacking requirements of cardboard of different sizes and can only be applied to cardboard of specific sizes; third, after the cardboard is stacked, it still needs to be manually removed, resulting in low mechanization. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a cardboard slitting and palletizing integrated machine with a more reasonable structure, stronger versatility, and higher degree of mechanization.

[0004] This integrated cardboard slitting and palletizing machine includes a cardboard slitting machine and a cardboard palletizing machine. The cardboard palletizing machine is located in front of the discharge end of the cardboard slitting machine. The cardboard palletizing machine includes a frame and a feeding mechanism. The feeding mechanism is characterized by: a baffle plate in front of the feeding mechanism; a lifting platform below the baffle plate; the lifting platform being vertically and flexibly mounted on the frame; and a power source driving the lifting platform to move up and down. Below the feeding mechanism is a material support mechanism, which includes a material support rod, a material support rod seat, and a material support power source. The material support rod is connected to the material support rod seat, and the power source drives the material support rod seat to move back and forth, bringing the material support rod above the lifting platform.

[0005] The frame is equipped with horizontal guide rails that extend forward and backward. The baffle plate is slidably mounted on the horizontal guide rails via a slider, and the forward and backward position of the baffle plate is adjustable.

[0006] The feeding mechanism includes an upper pressure roller, a front feeding pulley, a rear feeding pulley, and a conveyor belt. The conveyor belt is wound around the front feeding pulley and the rear feeding pulley, and the upper pressure roller is located above the conveyor belt.

[0008] The tensioning wheel is connected to the tensioning wheel seat, which is movably mounted on the adjusting seat. The adjusting seat is threaded with an adjusting screw, which can press against the tensioning wheel seat.

[0009] The front end of the feeding mechanism is equipped with a rear paper feeding mechanism, which includes a rear paper feeding board and a rear paper feeding power source that drives the rear paper feeding board to move back and forth. The rear paper feeding board is located below the front lower pulley, and the rear paper feeding board has a space for the material support rod to pass through.

[0010] The upper end of the rear platen has an extension, there are multiple front feed pulleys, and there is a space between two adjacent front feed pulleys. The extension of the rear platen is located in the space between two adjacent front feed pulleys.

[0011] Both sides of the frame are equipped with side paper-tapping mechanisms, which include side paper-tapping boards and a power source for driving the side paper-tapping boards to move left and right.

[0012] The feeding mechanism is connected to an incline mechanism at the rear of the conveying link. The incline mechanism is connected to the discharge end of the cardboard slitting machine. The incline mechanism includes an incline support, an incline belt, a front incline pulley, and a rear incline pulley. The front incline pulley and the rear incline pulley are both mounted on the incline support. The incline belt is wound around the front incline pulley and the rear incline pulley, and the incline belt feeds material forward and upward.

[0013] The lifting platform includes a platform support and a platform conveyor roller or platform conveyor belt installed on the platform support; a vertical guide rail is installed on the frame, and the platform support is slidably mounted on the vertical guide rail.

[0014] The cardboard slitting machine is equipped with a leveling roller at the discharge end.

Detailed Implementation

[0017] like Figure 1 As shown, this integrated cardboard slitting and palletizing machine includes a cardboard slitting machine A and a cardboard palletizing machine C. The cardboard palletizing machine C is located in front of the discharge end A1 of the cardboard slitting machine A. After large cardboard pieces are slitted by the cardboard slitting machine A, they are formed into smaller pieces. These smaller pieces exit from the discharge end A1 of the cardboard slitting machine A and enter the cardboard palletizing machine C. The cardboard is then stacked by the cardboard palletizing machine C to form a stack, which is then used for subsequent bundling and packaging. The cardboard slitting machine A includes a slitting roller, a slitting belt, and slitting blades. Under the action of the slitting belt, the cardboard adheres to the slitting roller. Driven synchronously by the slitting roller and the slitting belt, the cardboard moves, and the slitting blades slit the cardboard. The cardboard slitting machine A is existing technology, and its specific structure will not be described in detail.

[0018] like Figure 2 As shown, the cardboard palletizer C includes a frame 1 and a feeding mechanism 2. The feeding mechanism 2 conveys the cardboard forward. A baffle 3 is provided in front of the feeding mechanism 2, and a lifting platform 4 is provided below the baffle 3. The lifting platform 4 is vertically mounted on the frame 1. The lifting platform 4 is connected to a lifting power source 5 that drives the lifting platform 4 to move up and down. Driven by the lifting power source 5, the lifting platform 4 can move up and down. Figure 3 As shown, a material support mechanism 6 is provided below the feeding mechanism 2. The material support mechanism 6 includes a material support rod 60, a material support rod seat 61 and a material support power source. The material support rod 60 is connected to the material support rod seat 61. The material support power source can drive the material support rod seat 61 to move back and forth and bring the material support rod 60 to the top of the lifting platform 4.

[0019] The working principle of this cardboard palletizer C is as follows: Figure 3As shown, the slit cardboard is conveyed forward by the feeding mechanism 2. The cardboard is blocked by the front baffle 3 and falls onto the lifting platform 4. At the beginning of stacking, the lifting platform 4 is slightly lower than the feeding mechanism 2. As stacking continues, the lifting power source 5 drives the lifting platform 4 to descend continuously, always keeping the falling distance of the cardboard at a small height, so that the cardboard can be stacked smoothly. When the stacking reaches the set height, the material support power source drives the material support rod seat 61 to move forward, so that the material support rod 60 comes above the lifting platform 4. The material support rod 60 can temporarily hold the cardboard, and the cardboard slitting machine A does not need to stop. In this way, the cardboard that has been stacked on the lifting platform 4 has time to be sent out. After the cardboard that has been stacked on the lifting platform 4 is sent out, the lifting power source 5 drives the lifting platform 4 to move up quickly to the starting stacking position, while the material support power source drives the material support rod seat 61 to move backward, and the material support rod 60 quickly retracts backward. The cardboard falls onto the lifting platform 4 to continue stacking, and so on. This cardboard palletizer C can accommodate cardboard of different sizes by changing the front and rear positions of the baffle plate 3, making it more versatile. Moreover, it maintains a low drop during palletizing, resulting in more stable and flatter cardboard palletizing.

[0020] To facilitate adjustment of the front and rear position of the baffle plate 3, such as Figure 3 As shown, a horizontal guide rail 7 extending forward and backward is installed on the frame 1. The baffle plate 3 is slidably mounted on the horizontal guide rail 7 via a slider 30, and the forward and backward position of the baffle plate 3 is adjustable. When it is necessary to adjust the forward and backward position of the baffle plate 3, simply move the slider 30 on the horizontal guide rail 7, and then fix the slider 30 with bolts (the bolts are threaded onto the slider 30, and by tightening the bolts, the bolts act on the horizontal guide rail 7, thus fixing the slider 30).

[0021] like Figure 3 As shown, the feeding mechanism 2 includes an upper pressure roller 20, a front feeding pulley 22, a rear feeding pulley 23, and a conveyor belt 21. The conveyor belt 21 is wound around the front feeding pulley 22 and the rear feeding pulley 23, and the upper pressure roller 20 is located above the conveyor belt 21. After the cardboard enters the feeding mechanism 2, it enters between the upper pressure roller 20 and the conveyor belt 21. Through the conveying of the conveyor belt 21, the cardboard moves forward.

[0022] To ensure that the conveyor belt 21 is always taut, a belt tensioning mechanism is provided below the conveyor belt 21. The belt tensioning mechanism includes a tensioning wheel 24, which is located between the material support rod seat 61 and the rear pulley 23 (to prevent the tensioning wheel 24 from interfering with the material support rod seat 61). The tensioning wheel 24 pushes against the conveyor belt 21 from bottom to top, so that the conveyor belt 21 is always taut.

[0023] To adjust the tension of the conveyor belt 21, such as Figure 3As shown, the tensioning wheel 24 is connected to the tensioning wheel seat 25, which is movably mounted on the adjusting seat 26. An adjusting screw 27 is threaded onto the adjusting seat 26 and rests against the tensioning wheel seat 25. By adjusting the adjusting screw 27, the tensioning wheel seat 25 can move upwards, thus allowing the tensioning wheel 24 to adjust the force exerted on the conveyor belt 21, thereby adjusting the tension of the conveyor belt 21.

[0024] When stacking cardboard, in order to facilitate the sorting of the cardboard, such as... Figure 3 As shown, a rear paper-tapping mechanism is installed at the front end of the feeding mechanism 2. The rear paper-tapping mechanism includes a rear paperboard 9 and a rear paper-tapping power source that drives the rear paperboard 9 to move back and forth. The rear paperboard 9 is located below the front lower pulley 22, and has a space for the material support rod 60 to pass through. Whenever a piece of cardboard falls onto the lifting platform 4, the rear paper-tapping power source drives the rear paperboard 9 to tap forward, aligning the front edge of the cardboard with the guide plate 3, resulting in a neater and more aesthetically pleasing stack of cardboard. It is worth mentioning that, to prevent interference between the rear paperboard 9 and the material support rod 60, the rear paperboard 9 has a space for the material support rod 60 to pass through. This allows the rear paperboard 9 and the material support rod 60 to be staggered left and right, or a hole can be made in the rear paperboard 9 for the material support rod 60 to pass through.

[0025] like Figure 4 As shown, the feed front pulleys 22 are multiple, and there is a space between adjacent feed front pulleys 22. The upper end of the rear cardboard 9 has an extension 91, which is located in the space between adjacent feed front pulleys 22. When the support rod 60 retracts, the cardboard can be blocked by the extension 91 of the rear cardboard 9, preventing the support rod 60 from pulling the cardboard backward when it retracts. In addition, the extension 91 has a forward and downward inclined surface 92, which guides the cardboard to fall downward in an orderly manner.

[0026] To ensure the sides of the cardboard are aligned, side-feeding mechanisms are installed on both sides of frame 1, such as... Figure 3 As shown, the side-tapping mechanism includes a side-tapping plate 8 and a side-tapping power source that drives the side-tapping plate 8 to move left and right. Driven by the side-tapping power source, the side-tapping plate 8 taps down on the side of the plate, making the side of the plate align with the side of the plate.

[0027] To ensure that the feeding mechanism 2 has a certain height (the feeding mechanism 2 needs to have a certain height so that the lifting platform 4 can stack taller stacks of cardboard), such as Figure 1 As shown, an incline mechanism B is connected to the conveyor link behind the feeding mechanism 2. This incline mechanism B is connected to the discharge end A1 of the cardboard slitting machine A. Figure 2As shown, the incline mechanism B includes an incline support B1, an incline belt B2, a front incline pulley, and a rear incline pulley. Both the front and rear incline pulleys are mounted on the incline support B1. The incline belt B2 is wound around the front and rear incline pulleys, and feeds material forward and upward. Through the incline conveying action of the incline belt B2, the cardboard can enter the feeding mechanism 2, which is located at a higher position.

[0028] In order to automatically feed the stacked cardboard on lifting platform 4, such as Figure 3 As shown, the lifting platform 4 includes a platform support 40 and a platform conveying roller or platform conveyor belt 41 installed on the platform support 40. Through the conveying of the platform conveying roller or platform conveyor belt 41, the stacked cardboard can be conveyed to one side and sent to the discharge conveying mechanism D. Finally, the discharge conveying mechanism D sends it to the subsequent work station.

[0029] The discharge port of the lifting platform 4 is located on the side of the frame 1. This allows the discharge conveying mechanism D to be installed on the side of the frame 1, reducing the overall footprint of the machine in the front-to-back direction.

[0030] like Figure 3 As shown, a vertical guide rail 41 is installed on the frame 1, and the platform support 40 is slidably mounted on the vertical guide rail 41, which makes the lifting and lowering of the platform support 40 more stable.

[0031] Finally, it is worth mentioning that a leveling roller A2 is installed at the discharge end A1 of the cardboard slitter A. After the cardboard comes out of the cardboard slitter A, it is pressed down by the leveling roller A2 to prevent the cardboard from flying around and to ensure stable stacking of the cardboard in subsequent processes.
