[0017] like Figures 1 to 4As shown, this utility model provides a conveying device for cutting plastic drainage boards, including a base 1. A conveying groove is formed at the top of the base 1, and a conveyor 2 is installed inside the conveying groove. A bearing block 3 is provided at the output end of the conveyor 2, and the bearing block 3 is fixedly connected to the base 1. A conveying roller is rotatably connected inside the conveying groove, and the conveying roller is located to the right of the bearing block 3. The conveying roller assists in conveying the cut plastic drainage boards. A gantry frame 4 is fixedly connected to the top of the base 1. An electric telescopic rod 5 is fixedly connected to the center of the top of the gantry frame 4. The output end of the electric telescopic rod 5 passes through the gantry frame 4 and is fixedly connected to a connecting strip 6. A limiting post is symmetrically fixedly connected to the top of the connecting strip 6 about the electric telescopic rod 5, and the limiting post is slidably connected to the gantry frame 4. A cutting blade 7 is fixedly connected to the bottom of the connecting strip 6. A cutting groove is formed at the top of the bearing block 3, and the cutting... The groove is used in conjunction with the cutting blade 7. Supporting bars 8 are fixedly connected to both the front and back of the connecting bar 6. Several horizontally evenly arranged pressing holes are opened at the top of the supporting bar 8. Pressing pins 9 are slidably connected inside the pressing holes. Hollow bars 10 are fixedly connected to the bottom of the pressing pins 9. Compression springs 11 are sleeved on the surface of the pressing pins 9, and the two ends of the compression springs 11 are fixedly connected to the supporting bar 8 and the hollow bars 10 respectively. A sliding groove is opened at the bottom of the hollow bars 10. A sliding strip 12 is slidably connected inside the sliding groove. A pressing strip 13 is fixedly connected to the bottom of the sliding strip 12, and the height of the pressing strip 13 is lower than the height of the cutting blade 7. A lead screw 14 is rotatably connected to the center of the sliding groove through a bearing, and the lead screw 14 is threadedly connected to the sliding strip 12. A servo motor 15 is fixedly connected to the outside of the lead screw 14 through the hollow bars 10. A correction mechanism is provided on the top of the base 1.

[0018] refer to Figure 1 The calibration mechanism includes L-shaped mounting strips 16 installed on both sides of the top of the base 1. An electric push rod 17 is fixedly connected to the surface of the mounting strip 16. The output end of the electric push rod 17 passes through the mounting strip 16 and is fixedly connected to a calibration strip 18.

[0019] As a technical optimization of this utility model, by setting up the correction mechanism mounting strip 16, electric push rod 17, and correction strip 18, the electric push rod 17 can drive the correction strip 18 to move laterally, thereby correcting the position of the plastic drainage board that may be offset during the transmission process, ensuring that the edge of the board is aligned with the cutting reference, further improving the accuracy of the cutting position, and adapting to the problem of slight offset during board transportation.

[0020] refer to Figure 1 and Figure 3 The surface of the correction strip 18 is provided with a guide groove, and several evenly arranged guide rollers 19 are rotatably connected inside the guide groove.

[0021] As a technical optimization of this utility model, by setting a guide roller 19 in the guide groove of the correction strip 18, the sliding friction between the correction strip 18 and the plastic drainage board can be converted into rolling friction, reducing the wear on the surface of the board during the correction process, while reducing the correction resistance, making the correction action smoother, and protecting the appearance quality of the board.

[0022] refer to Figure 1 and Figure 3 The top of the base 1 is symmetrically fixedly connected to the mounting strip 16 with a fixing strip 20. The surface of the fixing strip 20 is provided with a limit hole. The back of the correction strip 18 is symmetrically fixedly connected to a limit post 21, and the limit post 21 is slidably connected to the limit hole.

[0023] As a technical optimization of this utility model, the fixed strip 20 and the limiting post 21 slide together, and the limiting post 21 is inserted into the limiting hole of the fixed strip 20, which constrains the movement direction of the correction strip 18, prevents the correction strip 18 from deflecting under the drive of the electric push rod 17, ensures the linearity of the correction action, and improves the correction accuracy and stability of the mechanism.

[0024] refer to Figure 4 The inner wall of the chute is fixedly connected with multiple evenly arranged sliding columns, and the sliding columns pass through the slide bar 12 and are slidably connected to the slide bar 12.

[0025] As a technical optimization of this utility model, the sliding column on the inner wall of the slide groove is slidably connected to the slide bar 12, which can help support the slide bar 12, reduce the shaking of the slide bar 12 when it slides under the drive of the lead screw 14, ensure the accuracy of the position adjustment of the lower pressure bar 13, and at the same time disperse the contact stress between the slide bar 12 and the slide groove, thus extending the service life of the component.

[0026] refer to Figure 1 The front of the gantry 4 is equipped with a control box 22, and the front of the control box 22 is equipped with a human-machine interface panel.

[0027] As a technical optimization of this utility model, the control box 22 and human-machine interface panel on the gantry frame 4 facilitate the operator to control the operating parameters (such as transmission speed, cutting spacing, and position of the pressure strip 13) of components such as the conveyor 2, electric telescopic rod 5, and servo motor 15 in real time, thereby improving the ease of operation and intelligence of the device and adapting to the cutting needs of plastic drainage boards of different specifications.

[0028] The working principle and usage process of this utility model are as follows: When using this conveying device to cut plastic drainage boards, the operator first starts the device through the human-machine interface panel of the control box 22 on the gantry frame 4. The plastic drainage board is placed on the conveyor 2 in the transmission groove of the base 1, and the conveyor 2 conveys it to the bearing block 3, with the right-side conveying roller assisting in the conveying. At this time, the electric push rod 17 on the mounting strip 16 drives the correction strip 18 to move. The limiting post 21 on the back of the correction strip 18 slides in the limiting hole of the fixing strip 20, and cooperates with the guide roller 19 in the guide groove to roll and correct the position of the board, ensuring that it is accurately delivered to the cutting point of the bearing block 3. The conveyor 2 then stops. Then, according to the distribution of the protrusions of the plastic drainage board, the servo motor 15 is started, which drives the lead screw 14 in the hollow strip 10 to rotate, so that the slide bar 12 in the slide groove cooperates with the slide column to slide stably and drive the lower pressure strip 13 to move to the gap between the protrusions. The electric telescopic rod 5 is activated, its output end passing through the gantry 4, driving the connecting rod 6 to descend. The limiting post at the top of the connecting rod 6 slides within the gantry 4, guiding the support rod 8 downwards. The pressing post 9 and the hollow strip 10 move downwards simultaneously. Because the pressing strip 13 is lower than the cutting blade 7, it first presses the board material to fix it to the bearing block 3. The connecting rod 6 continues to descend, causing the hollow strip 10 to rise, compressing the compression spring 11 on the pressing post 9, enhancing the fixing effect. Subsequently, the cutting blade 7, in conjunction with the cutting groove of the bearing block 3, completes the cutting. After cutting, the electric telescopic rod 5 drives the connecting rod 6 to rise, the compression spring 11 returns to its original position, the pressing strip 13 disengages, the servo motor 15 returns the pressing strip 13 to its original position, and the conveyor 2 transports the cut board material through the conveyor rollers, simultaneously conveying the next board material to be cut, repeating the operation.

[0029] It should be noted that the electric telescopic rod 5 disclosed above can be selected from the XTL100 series or FY011 series, which is suitable for driving the cutting action of small and medium loads. It has the characteristics of adjustable stroke and smooth operation. The servo motor 15 can be selected from the Mitsubishi HC-KFS series or Delta ASD-B series, with corresponding drivers, to meet the high-precision control requirements of the lower pressure bar 13 position adjustment. The electric push rod 17 can be selected from the DTZ series or L-type electric push rod, which is adapted to the lateral position adjustment of the correction bar 18. The running speed can be adjusted through the control box 22. The control box 22 can adopt a PLC control module (such as Siemens S7-200SMART) and be paired with a touch screen (such as Weintek TK6071IP) to form a human-machine interaction system to realize the linkage control of various components. The control box 22 controls the operation of the electric telescopic rod 5, servo motor 15 and electric push rod 17 using methods commonly used in the existing technology.
