Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding machine for processing wood-plastic flooring. Background Technology

[0002] Wood-plastic composite (WPC) flooring is a new type of environmentally friendly wood-plastic composite material product. It is made by adding recycled plastic to the lignin produced during the production of medium- and high-density fiberboard and then extruding it to produce WPC flooring. It has been widely used in building decoration, outdoor landscaping and other fields. The uniformity of the flooring thickness is one of the key indicators for measuring product quality, which directly affects the laying effect, service life and stability of subsequent processing steps.

[0003] In the production and processing of wood-plastic composite flooring, the smoothing process is a key step to ensure the flatness and thickness accuracy of the flooring surface. In daily operation, the flooring is conveyed to the sanding component through the smoothing machine conveyor mechanism for sanding to remove surface defects and complete the thickness adjustment.

[0004] However, problems exist in actual production. After long-term use, the sanding belt of the sanding component will experience localized wear due to continuous friction with the floor, resulting in uneven distribution of abrasive grains on the sanding belt surface. This directly causes differences in cutting force in the corresponding sanding areas. The original floor surface after sanding is prone to forming uneven surfaces of varying thickness, causing quality problems such as inconsistent thickness of wood-plastic flooring after sanding. More importantly, the post-production sampling inspection method cannot achieve real-time monitoring of all batches of products. This makes it easy for unqualified products to flow into subsequent processes, which not only increases the material and labor costs of rework, but may also have an adverse impact on the overall quality stability of the final product. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding machine for processing wood-plastic composite flooring. It solves the problem that after long-term use, the sanding belt of the sanding component experiences localized wear due to continuous friction with the flooring, resulting in uneven distribution of abrasive grains on the sanding belt surface. This directly causes differences in cutting force in corresponding sanding areas. As a result, the flooring surface, after sanding, easily develops uneven surfaces of varying thickness, leading to inconsistent grinding thickness in the wood-plastic composite flooring. More importantly, the current post-processing sampling method cannot achieve real-time monitoring of the entire batch of products. This allows defective products to easily flow into subsequent processes, increasing material and labor costs for rework and potentially negatively impacting the overall quality stability of the final product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A grinding machine for processing wood-plastic composite flooring includes a conveying end and a machine body. The discharge end of the conveying end is equipped with a detection mechanism for detecting the thickness of the wood-plastic composite flooring. The detection mechanism includes a mounting frame, sensors, a data processing module, and an alarm. The mounting frame is located outside the conveying end. There are two sensors, each fixedly connected to one end of the mounting frame to detect the thickness information of the wood-plastic composite flooring. The data processing module is fixedly connected to the upper surface of the mounting frame to receive the thickness information transmitted by the sensors. Two laser displacement sensors are electrically connected to the data processing module. The alarm is fixedly connected to the upper surface of the mounting frame to issue an alarm. The data processing module is electrically connected to the alarm.

[0007] Preferably, two fixing blocks are fixedly installed on the lower surface of the conveying end, and the two ends of the mounting frame are respectively snapped onto the outside of the two fixing blocks. Each fixing block has a bolt threadedly connected to its upper surface to limit the movement of the mounting frame. Each fixing block has a threaded hole on its outside, and the bolt is threadedly connected to the inside of the threaded hole.

[0008] Preferably, the mounting frame has cable holes on one side corresponding to each sensor.

[0009] Preferably, both the inlet and outlet ends of the conveyor are equipped with limiting mechanisms to restrict the position of the wood-plastic composite flooring. Each limiting mechanism includes a fixed frame and a limiting plate. There are two fixed frames, both of which are fixedly installed at both ends of the conveyor. The limiting plate is slidably connected to the inner side of the fixed frame. Each fixed frame has a screw hole on its outer side, which communicates with the inner side of the fixed frame. Each screw hole is threaded with a screw rod for fixing the position of the limiting plate. A rubber pad is fixedly installed on the outer side of each limiting plate. Compared with the prior art, the present invention has the following beneficial effects: Wood-plastic composite (WPC) flooring enters through the feed inlet at the conveyor end, undergoes sanding by the sanding components, and then exits through the discharge end. At this point, laser displacement sensors installed at the top and bottom of the conveyor end detect the position information of the upper and lower surfaces of the WPC flooring, respectively, and transmit this information to the data processing module. The data processing module calculates the thickness of the WPC flooring based on the received position information and compares the calculated thickness with a preset standard thickness range. When the calculated thickness exceeds the standard thickness range, the data processing module sends a control signal to the alarm, which then emits an audible and visual alarm to remind operators to promptly handle the defective WPC flooring, preventing defective products from flowing into subsequent processes. This effectively improves product quality, reduces rework material and labor costs, and enhances production response efficiency and economy. Attached Figure Description

[0013] This application provides a grinding machine for processing wood-plastic composite flooring, which effectively solves the problem that after long-term use, the sanding belt of the sanding component will experience localized wear due to continuous friction with the floor, resulting in uneven distribution of abrasive grains on the sanding belt surface. This directly causes differences in cutting force in the corresponding sanding areas. Originally, the floor surface after sanding is prone to forming uneven surfaces of varying thickness, leading to quality problems such as inconsistent grinding thickness of wood-plastic composite flooring. More importantly, the post-processing sampling inspection method cannot achieve real-time monitoring of the entire batch of products. This makes it easy for unqualified products to flow into subsequent processes, which not only increases the material and labor costs of rework, but may also adversely affect the overall quality stability of the final product.

[0014] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application effectively solves the problem that after long-term use, the sanding belt of the sanding component will experience localized wear due to continuous friction with the floor, resulting in uneven distribution of abrasive grains on the sanding belt surface. This directly causes differences in cutting force in the corresponding sanding areas. Originally, the floor surface after sanding is prone to forming uneven surfaces of varying thickness, leading to quality problems such as inconsistent thickness of wood-plastic flooring after sanding. More importantly, the post-production sampling inspection method cannot achieve real-time monitoring of the entire batch of products. This makes it easy for unqualified products to flow into subsequent processes, which not only increases the material and labor costs of rework, but may also adversely affect the overall quality stability of the final product. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides a grinding machine for processing wood-plastic composite flooring, including a conveying end 1 and a machine body 15. The discharge end of the conveying end 1 is equipped with a detection mechanism for detecting the thickness of the wood-plastic composite flooring. The detection mechanism includes a mounting frame 2, sensors 3, a data processing module 4, and an alarm 5. The mounting frame 2 is located outside the conveying end 1. There are two sensors 3, each fixedly connected to both ends of the mounting frame 2 to detect the thickness information of the wood-plastic composite flooring. The sensors 3 are laser displacement sensors 3. The data processing module 4 is fixedly connected to the upper surface of the mounting frame 2 to receive the thickness information transmitted by the sensors 3. The data processing module 4 is a microcontroller or PLC controller. The two laser displacement sensors 3 are electrically connected to the data processing module 4. The alarm 5 is fixedly connected to the upper surface of the mounting frame 2 to issue an alarm. The data processing module 4 is electrically connected to the alarm 5. The sensors 3, data processing module 4, and alarm 5 can be installed according to actual conditions, such as by screws or glue.

[0015] Two fixing blocks 6 are fixedly installed on the lower surface of the conveying end 1. The two ends of the mounting frame 2 are respectively snapped onto the outside of the two fixing blocks 6. Each fixing block 6 has a bolt 7 threadedly connected to its upper surface to restrict the movement of the mounting frame 2. Each fixing block 6 has a threaded hole 8 on its outside, and the bolt 7 is threadedly connected to the inside of the threaded hole 8.

[0016] The mounting frame 2 has a cable hole 9 on one side corresponding to each sensor 3. The two laser displacement sensors 3 are electrically connected to the data processing module 4 through signal cables. The cables are arranged neatly through the cable holes 9 on the mounting frame 2 to ensure stable signal transmission.

[0017] Both the infeed end and the discharge end of the conveying end 1 are equipped with limiting mechanisms for restricting the position of the wood-plastic flooring. Each limiting mechanism includes a fixed frame 10 and a limiting plate 11. There are two fixed frames 10, and both fixed frames 10 are fixedly installed at both ends of the conveying end 1. The limiting plate 11 is slidably connected to the inner side of the fixed frame 10.

[0018] Each fixing bracket 10 has a screw hole 12 on its outer side, which communicates with the inner side of the fixing bracket 10. Each screw hole 12 is threaded with a screw rod 13 for fixing the position of the limiting plate 11.

[0019] Each limiting plate 11 is fixedly installed with a rubber pad 14. The rubber pad 14 has good elasticity and flexibility. When the wood-plastic flooring comes into contact with the limiting plate 11 during the conveying process, the rubber pad 14 can absorb the impact force through its own deformation, avoiding scratches, chipping or surface damage caused by direct collision between the edge of the wood-plastic flooring and the limiting plate 11. At the same time, the surface of the rubber material has a high coefficient of friction, which increases the friction with the side of the wood-plastic flooring.

[0020] The wood-plastic composite (WPC) flooring enters through the feed inlet of conveyor 1, undergoes sanding by the sanding assembly, and then exits through the discharge end of conveyor 1. At this time, laser displacement sensors 3, installed at the top and bottom of conveyor 1, detect the position information of the upper and lower surfaces of the WPC flooring, respectively, and transmit this position information to the data processing module 4. The data processing module 4 calculates the thickness of the WPC flooring based on the received position information and compares the calculated thickness with the preset standard thickness range. When the calculated thickness exceeds the standard thickness range, the data processing module 4 sends a control signal to the alarm 5, which then issues an audible and visual alarm to remind operators to promptly handle the substandard WPC flooring, preventing substandard products from flowing into subsequent processes. This effectively improves product quality, reduces rework material and labor costs, and enhances production response efficiency and economy.

[0021] Example 2 Adjust the distance between the two relative limiting plates 11 according to the width of the wood-plastic flooring. First, rotate the screw 13 to move the end of the screw 13 away from the limiting plate 11. At this time, the limiting plate 11 can be moved. After the position of the limiting plate 11 is adjusted, rotate the screw 13 in the opposite direction so that the rubber pad 14 at the end of the screw 13 fits tightly against the outside of the limiting plate 11. The limiting plate 11 is fixed by the friction between the rubber pad 14 and the limiting plate 11. Therefore, when the wood-plastic flooring enters from the feed port of the conveying end 1 or moves out from the discharge end, the wood-plastic flooring is located between the two limiting plates 11, which avoids the wood-plastic flooring from shifting or tilting during the conveying process. This ensures that the laser displacement sensors 3 set at the top and bottom of the conveying end 1 can accurately detect the position information of the upper and lower surfaces of the wood-plastic flooring, providing a reliable guarantee for subsequent thickness detection and quality judgment.

[0022] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
