Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard production, specifically a double waste discharge system for the cross-cutting paper output section. Background Technology

[0002] When the cross-cutting machine on the corrugated cardboard production line is producing cardboard, it needs to change orders according to the cardboard specifications. When changing orders, a cardboard with a joint is generated, which results in a waste board. If this cardboard is transported to the stacker machine according to the normal production process, it will be sorted and collected by the stacker machine, causing trouble for subsequent processes.

[0003] When the production speed of a corrugated cardboard production line is low (below 200 meters / minute), the number of order changes per shift is small, less than 80 orders, resulting in less waste boards. However, current corrugated cardboard production lines have reached a production speed of 450 meters / minute, with order changes per shift exceeding 400 orders. At such high speeds, the large number of waste boards generated during order changes must be discharged from the paper output section of the cross-cutting machine and cannot be directly conveyed to the stacking machine, increasing the workload.

[0004] In summary, this utility model provides a dual waste discharge system for the transverse paper output section to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a double waste discharge system for the cross-cutting paper output section, which solves the problem in the prior art that the waste board needs to be discharged from the cross-cutting paper output section when changing single waste boards, and cannot be directly transported to the stacker, thus increasing the workload.

[0006] A double-discharge waste system for the cross-cutting paper output section includes a corrugated paper machine. The corrugated paper machine includes a conveyor roller conveyor, which includes a conveyor belt and an upper waste discharge plate. A waste trough is opened in the middle of the conveyor roller conveyor. A lower waste discharge baffle and an upper waste discharge plate are provided in the waste trough. The conveyor belt and the upper waste discharge plate are respectively located at both ends of the waste trough. The lower waste discharge baffle is rotatably connected to the conveyor roller conveyor through a baffle shaft. One end of the conveyor belt is located at the end of the conveyor roller conveyor, and the other end is located at the bottom of the lower waste discharge baffle. A conveyor bar is installed on the conveyor roller conveyor. The conveyor bar is located at the upper end of the upper waste discharge plate. The upper waste discharge plate is rotatably connected to the conveyor roller conveyor through an upper waste discharge shaft.

[0007] Furthermore, a tilting plate is fixedly sleeved on the surface of the baffle shaft, and a lower exhaust gas cylinder is installed at the bottom of the conveyor roller, with the piston rod of the lower exhaust gas cylinder rotatably connected to one end of the tilting plate.

[0008] Furthermore, a push plate is fixedly connected to the surface of the upper waste shaft, and an upper waste cylinder is installed at the bottom of the conveyor roller. The piston rod of the upper waste cylinder is rotatably connected to one end of the push plate.

[0009] Furthermore, the upper waste plate is located on the conveyor roller table near one end of the upper waste plate, and the lower waste baffle is located on the conveyor roller table near one end of the conveyor belt.

[0010] Furthermore, a waste paper collection vehicle is provided at the bottom of the conveyor roller conveyor.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model effectively solves the problem of handling waste boards during the production of corrugated cardboard by setting up a double waste discharge system. Through the synergistic effect of the lower waste discharge baffle and the upper waste discharge board, the waste boards can be discharged quickly and accurately from the conveyor roller, avoiding the waste boards from entering the stacking machine and interfering with subsequent processes.

[0013] 2. In this invention, the lower and upper exhaust cylinders drive the tilting plate and push plate respectively, achieving automated control, greatly reducing manual intervention and improving production efficiency. Furthermore, the waste paper collection cart facilitates the centralized collection of discharged waste boards, further optimizing the working environment and reducing cleaning costs. This invention features a reasonable structural design and simple operation, making it suitable for high-speed corrugated cardboard production lines. It significantly improves the stability and efficiency of the overall production process. This double-exhaust system can better discharge waste boards generated during order changes in both low-speed and high-speed conditions of corrugated cardboard production lines, solving the problem of waste boards causing problems for subsequent processes.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-4As shown, this utility model provides a double waste discharge system for the transverse paper output section, including a corrugated paper machine. The corrugated paper machine includes a conveyor roller track, which includes a conveyor belt 1 and an upper waste discharge plate 6. A waste trough is opened in the middle of the conveyor roller track. A lower waste discharge baffle 3 and an upper waste discharge plate 6 are provided in the waste trough. The conveyor belt 1 and the upper waste discharge plate 6 are respectively located at both ends of the waste trough. The lower waste discharge baffle 3 is rotatably connected to the conveyor roller track through a baffle shaft. One end of the conveyor belt 1 is located at the end of the conveyor roller track, and the other end is located at the bottom of the lower waste discharge baffle 3. A conveyor row 8 is installed on the conveyor roller track. The conveyor row 8 is located at the upper end of the upper waste discharge plate 6. The upper waste discharge plate 6 is rotatably connected to the conveyor roller track through an upper waste discharge shaft 5.

[0022] In one embodiment of this utility model, a tilting plate is fixedly sleeved on the surface of the baffle shaft, and a lower exhaust gas cylinder 2 is installed at the bottom of the conveyor roller. The piston rod of the lower exhaust gas cylinder 2 is rotatably connected to one end of the tilting plate.

[0023] As one embodiment of this utility model, a push plate is fixedly connected to the surface of the upper waste shaft 5, and an upper waste cylinder 7 is installed at the bottom of the conveying roller. The piston rod of the upper waste cylinder 7 is rotatably connected to one end of the push plate.

[0024] In one embodiment of this utility model, the upper waste plate 6 is disposed on the conveyor roller table near one end of the upper waste plate 6, and the lower waste baffle 3 is disposed on the conveyor roller table near one end of the conveyor belt 1.

[0025] As one embodiment of this utility model, a waste paper collection vehicle 4 is provided at the bottom of the conveyor roller conveyor.

[0026] The upper waste discharge system includes an upper waste discharge shaft 5, an upper waste discharge plate 6, and an upper waste discharge cylinder 7. When the corrugated cardboard production line is running at high speed (180 mi / min), the cardboard speed is high and has a certain impulse. The probability of waste plates getting stuck in the lower waste discharge system is relatively high. At this time, a waste plate generated during order change on the corrugated cardboard production line is processed by the upper waste discharge system. After the waste plate is generated, it moves to the upper waste discharge system position, the upper waste discharge cylinder 7 extends, and pushes the upper waste discharge shaft 5 to rotate. The upper waste discharge shaft 5 is fixedly connected to the upper waste discharge baffle 6. The upper waste discharge baffle 6 rotates along the upper waste discharge shaft 5. At this time, the upper waste discharge baffle 6 is raised, as... Figure 3 The upper waste baffle 6 is horizontally aligned with the conveyor belt 8. A waste board is conveyed upward to the conveyor belt 8 under the guidance of the upper waste baffle 6. Finally, the waste board is collected as a whole by the conveyor belt equipment of the conveyor belt 8.

[0027] The lower discharge system includes a conveyor belt 1, a lower discharge waste cylinder 2, a lower discharge waste baffle 3, and a waste paper collection cart 4. When the corrugated cardboard production line operates at a low speed (<180 mi / min), the cardboard speed is relatively low. At this time, a waste board generated during order change is handled by the lower discharge system. After the waste board is generated, it moves to the lower discharge system position, the lower discharge waste cylinder 2 extends, and pushes the lower discharge waste baffle 3 to lift. Figure 2 A waste board moves downward under the guidance of the lower waste baffle 3, and runs on the conveyor belt 1 to be transported to the waste paper cart 4.

[0028] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
