[0002] New building materials are new types of building materials that are different from traditional bricks, tiles, lime sand and gravel. The industry has made a clear definition of the scope of new building materials, that is, new building materials mainly include new wall materials, new waterproof sealing materials, new thermal insulation materials and decorative materials. One of the most commonly used raw materials for new building materials is plastic, which has excellent corrosion resistance and antioxidant properties. Compared with current bricks, tiles, lime sand and gravel, it has a longer service life and is lighter in weight. It is widely used. After production, new plastic building materials need to be cut into blocks or strips and cut to size according to the purchaser.

[0003] The publication number is CN108189094B, which provides a cutting device for plastic plates, including a machine base and a cutting knife, a support plate and a processing table are arranged on the machine base; a first spring is arranged on the support plate, and a lifting plate is arranged on the first spring; a motor is arranged on one end of the lifting plate, and the rotating shaft of the motor is fixedly connected to the cutting knife, and an iron inclined wedge is arranged on the other end of the lifting plate; a processing groove is arranged on the processing table, rocker arms are hinged on both sides of the processing groove, and a second spring is arranged between the rocker arms and the processing table; fixed shafts are arranged on both sides of the processing groove, and guide wheels are rotatably connected to the fixed shafts; a threaded hole is arranged on the side wall of the processing table, and a threaded rod is threadedly connected in the threaded hole, and a permanent magnet is arranged on the threaded rod to abut against the inclined wedge, and the permanent magnet is inclined toward the processing table, and the thickness of the permanent magnet is greater than the thickness of the inclined wedge. This scheme mainly solves the problem that the current plastic plate cutting method is inconvenient to collect powder chips.

[0004] The cutting device provided above mainly solves the problem that the current plastic plate cutting method is inconvenient to collect powder chips. However, there are still some other problems after the plastic plate is cut. Burrs or sharp parts remain at the cut position of the plastic plate. During use, it is inevitable that the operator's hands will be injured, or the sharp burrs will scratch, pull and tear the plastic film, and the plastic film will lose its sealing and covering effect on the plastic plate.

[0005] To this end, the present invention provides a new type of cutting equipment for manufacturing building materials. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the new type of cutting equipment for manufacturing building materials described in the present invention comprises a cutting machine, and a grinding assembly is provided at the rear side of the electric saw blade of the cutting machine; the grinding assembly comprises a connecting rod, a connecting block and a grinding unit; one end of the connecting rod is fixedly connected to the cutting machine housing, and the other end of the connecting rod is fixedly connected to the end surface of the connecting block; the cross section of the connecting block is in the shape of an "I" character, and a plurality of grinding units are installed in two concave parts of the connecting block;

[0008] The grinding unit comprises a motor, a driving gear, a driven gear and a grinding wheel; the motors are installed inside the upper and lower ends of the connecting block, the output ends of the two motors are arranged opposite to each other, the output ends of the motors are fixedly connected to the driving gears, the two sides of each driving gear are meshed with driven gears, the driven gears are fixedly connected to the grinding wheels, one end of the grinding wheel is rotatably connected to the horizontal side walls of the two inner concave parts of the connecting block, the other end of the grinding wheel is rotatably connected to the vertical side walls of the inner concave surface of the connecting block, and the two grinding wheels on the inner concave part on the same side of the connecting block are arranged in an "eight" shape, and the other end of the two grinding wheels The ends are arranged close to each other; when the cutting machine moves and cuts along the surface of the plate, the connecting block is embedded in the cutting seam from one side of the plate. At this time, the cut surface of the plate is placed in the concave part of the connecting block, and the motor is driven. The motor drives the driven gear to rotate through the active gear, and the driven gear drives the grinding wheel to rotate. The grinding wheel grinds the cut surface of the plate, and grinds the burrs and sharp corners at the edge of the port to make it smooth and round, thereby reducing the possibility of burrs and corners scratching and tearing some plastic film building materials after cutting, and at the same time reducing the possibility of sharp burrs scratching the hands of workers.

[0009] Preferably, the lower half of each grinding wheel is in the shape of a bullet head, and the middle position of each grinding wheel is in the shape of an arc; the design of the shape of the grinding wheel allows the grinding wheel to present a smooth and rounded surface after grinding the broken surface of the plate, thereby reducing the squeezing pain of the edge of the plate on the base of the operator's hand.

[0010] Preferably, a plurality of extrusion pockets are evenly arranged on the outer ring of the upper half of the grinding wheel, and air holes are opened on the extrusion pockets, and the exhaust direction of the air holes is inclined to the vertical side wall of the inner concave surface of the connecting block; a chip removal hole is opened on the inner concave horizontal surface of the connecting block between the two adjacent grinding units, and a collecting shell is provided below the chip removal hole, and the collecting shell is magnetically adsorbed on the lower surface of the connecting block; after grinding the edge of the plate, the debris splashes onto the surface at the position of the plate break. If the debris is not processed, the debris spreads to the surface of the plate. When the adjacent plates are attached and stacked, the debris particles will scratch and damage the surface of the plate. Therefore, by providing an extrusion pocket, when the grinding wheel is grinding the plate, the extrusion pocket on the grinding wheel indirectly squeezes the surface of the plate, and at the same time, the gas in the extrusion pocket bulges out and blows the debris on the surface of the plate to the position of the chip removal hole, and then the debris falls into the collecting shell along the chip removal hole.

[0011] Preferably, a rotating groove is provided on the water surface side wall of the inner concave surface of the connecting block, and an extrusion wheel is provided in the rotating groove. The middle rotating shaft of the extrusion wheel is rotatably connected in the rotating groove, and the outer ring of the extrusion wheel is pressed on the surface of the grinding material; after the plate is cut and broken, the plate at the broken part has a tendency to warp up, and this tendency will tilt and squeeze on the grinding wheel, thereby increasing the friction force of the relative movement between the plate and the connecting block, and at the same time increasing the power of the motor. For this purpose, an extrusion wheel is provided to squeeze and limit the broken port of the plate, constrain the broken port, reduce the warping amplitude of the broken port of the plate, thereby reducing the tilting extrusion force of the plate on the connecting block, and ensuring the smoothness of the relative movement between the connecting block and the broken port of the plate.

[0012] Preferably, the rotating groove is opened at an angle, and the direction of the rotating groove is inclined to point to the middle position of the inner concave surface of the connecting block, and a buffer groove is opened in the rotating groove at the connection point with the rotating shaft, and a spring is provided in the buffer groove, one end of the spring is squeezed in the buffer groove, and the other end of the spring is squeezed on the rotating shaft; the setting of the inclined direction of the rotating groove and the extrusion wheel makes it possible for the extrusion wheel to push the plate toward the disconnection position during the relative movement between the plate and the connecting block, thereby reducing the tendency of the disconnection ports to separate from each other and the tendency of the disconnection ports of the plate to warp, so that the grinding wheel can grind and polish the corners of the disconnection ports more effectively; and the setting of the spring makes the extrusion wheel adaptable to the extrusion restrictions on plates of different thicknesses.

[0013] Preferably, a ring-shaped extrusion plate is provided on the edge of the extrusion wheel, the extrusion plate is fixedly connected to the extrusion wheel, and multiple rows of elastic tentacles are evenly provided on the outer surface of the extrusion plate, and the elastic tentacles are inclined to point in the concave direction of the connecting block; by providing the extrusion plate, the extrusion surface of the extrusion wheel on the plate is increased, and at the same time, multiple rows of elastic tentacles are provided on the extrusion plate to increase the friction between the extrusion plate and the plate, thereby reducing the possibility of slipping between the plate and the extrusion plate.

To this end, by setting a cleaning mechanism, during the process of the elastic tentacle on the extrusion plate rotating into the rotating groove, the cleaning rod in the groove of the rotating groove is embedded in the elastic tentacle and pushes out the debris wrapped inside it. Thanks to the deformation of the elastic tentacle, the friction force of the elastic tentacle on the plate is guaranteed.

[0015] Preferably, the two ends of the cleaning rod are configured to be pointed, and a scraper is provided on the surface of the middle part; the shape of the cleaning rod facilitates the insertion of the end of the cleaning rod into the elastic tentacle, preventing the end of the cleaning rod from pressing against the elastic tentacle when the extrusion wheel moves along the buffer groove, and a hanging piece is provided in the middle position of the cleaning rod, which is beneficial to cleaning the debris in the elastic tentacle more thoroughly.

[0016] Preferably, a chip removal pipe is provided at the lower end of the chip removal hole, the chip removal pipe is connected to the collection shell, and the outer circle of the chip removal pipe is provided with a ring-shaped protrusion; by using an external vacuum cleaner, the vacuum cleaner pipe is plugged into the chip removal pipe, the debris is collected centrally, and the debris is prevented from spilling out.

At this time, the cut surface of the plate is placed in the concave part of the connecting block 3, and the motor 4 is driven. The motor 4 drives the driven gear 6 to rotate through the driving gear 5, and the driven gear 6 drives the grinding wheel 7 to rotate. The grinding wheel 7 grinds the cut surface of the plate, and grinds the burrs and sharp corners at the edge of the port to be smooth and round, thereby reducing the possibility of burrs and corners scratching and tearing some plastic film building materials after cutting, and at the same time reducing the possibility of sharp burrs scratching the hands of workers.

[0034] Reference Figure 3 The lower part of each grinding wheel 7 is in the shape of a bullet head, and the middle part of each grinding wheel 7 is in the shape of an arc. The design of the shape of the grinding wheel 7 makes the grinding wheel 7 present a smooth and rounded surface after grinding the broken surface of the plate, thereby reducing the pain caused by the edge of the plate squeezing the base of the operator's hand.

[0035] Reference Figure 3 The outer ring of the upper half of the grinding wheel 7 is evenly provided with a plurality of extrusion bags 8, and air holes are opened on the extrusion bags 8, and the exhaust direction of the air holes is inclined to the vertical side wall of the inner concave surface of the connecting block 3; a chip removal hole 9 is opened on the inner concave horizontal surface of the connecting block 3 between the two adjacent grinding units, and a collecting shell 10 is provided below the chip removal hole 9, and the collecting shell 10 is magnetically adsorbed on the lower surface of the connecting block 3; after grinding the edge of the plate, the debris splashes onto the surface of the plate at the position of the plate break. If the debris is not processed, the debris spreads to the surface of the plate. When the adjacent plates are attached and stacked, the debris particles will scratch and damage the surface of the plate. Therefore, by setting the extrusion bag 8, when the grinding wheel 7 is grinding the plate, the extrusion bag 8 on the grinding wheel 7 is indirectly squeezed on the surface of the plate, and at the same time, the gas in the extrusion bag 8 bulges out and blows the debris on the surface of the plate to the position of the chip removal hole 9, and then the debris falls into the collecting shell 10 along the chip removal hole 9.

[0036] Reference Figure 3 A rotating groove 11 is provided on the water surface side wall of the inner concave surface of the connecting block 3, and an extrusion wheel 12 is provided in the rotating groove 11. The middle rotating shaft of the extrusion wheel 12 is rotatably connected in the rotating groove 11, and the outer ring of the extrusion wheel 12 is pressed on the surface of the grinding material; after the plate is cut and broken, the plate at the broken part has a tendency to rise, and this tendency will be tilted and pressed on the grinding wheel 7, thereby increasing the friction force of the relative movement between the plate and the connecting block 3, and at the same time increasing the power of the motor 4. For this purpose, an extrusion wheel 12 is provided to squeeze and limit the broken port of the plate, constrain the broken port, reduce the lifting amplitude of the broken port of the plate, thereby reducing the tilting extrusion force of the plate on the connecting block 3, and ensuring the relative movement smoothness between the connecting block 3 and the broken port of the plate.

[0037] Reference Figure 1The rotating groove 11 is opened at an angle, and the direction of the rotating groove 11 is inclined to point to the middle position of the inner concave surface of the connecting block 3, and a buffer groove 13 is opened at the connection point between the rotating groove 11 and the rotating shaft, and a spring is arranged in the buffer groove 13, one end of the spring is squeezed in the buffer groove 13, and the other end of the spring is squeezed on the rotating shaft; the setting of the inclined direction of the rotating groove 11 and the extrusion wheel 12 makes it possible for the extrusion wheel 12 to push the plate to the disconnection position during the relative movement between the plate and the connecting block 3, reducing the tendency of the disconnection ports to separate from each other and reducing the tendency of the disconnection ports of the plate to warp, so that the grinding wheel 7 can grind and polish the corners of the disconnection ports more effectively; and the setting of the spring makes the extrusion wheel 12 adaptable to the extrusion restriction of plates of different thicknesses.

[0038] Reference Figure 3-5 The edge of the extrusion wheel 12 is provided with a ring-shaped extrusion plate 14, the extrusion plate 14 is fixedly connected to the extrusion wheel 12, and multiple rows of elastic tentacles 15 are evenly arranged on the outer surface of the extrusion plate 14, and the elastic tentacles 15 are inclined to point to the concave direction of the connecting block 3; by providing the extrusion plate 14, the extrusion surface of the extrusion wheel 12 on the plate is increased, and at the same time, multiple rows of elastic tentacles 15 are provided on the extrusion plate 14, so as to increase the friction between the extrusion plate 14 and the plate, and reduce the possibility of slipping between the plate and the extrusion plate 14.

[0039] Reference Figure 5-6 , a cleaning mechanism is provided on the inner side of the notch of the rotating groove 11; the cleaning mechanism includes a fixing rod 16 and a cleaning rod 17; one end of the fixing rod 16 is fixedly connected to the inner side wall of the notch of the rotating groove 11, and the other end of the fixing rod 16 is fixedly connected to the middle position of the cleaning rod 17, and the end of the cleaning rod 17 is embedded in the enclosed area between the elastic tentacle 15 and the extrusion plate 14; when the elastic tentacle 15 is extruded with the surface of the plate, some debris on the surface of the plate will enter the area enclosed between the elastic tentacle 15 and the extrusion plate 14, causing the debris to adhere to the inside of the elastic tentacle 15, affecting the extrusion deformation of the elastic tentacle 15, and reducing the extrusion friction force of the elastic tentacle 15 on the plate. For this reason, by setting a cleaning mechanism, when the elastic tentacle 15 on the extrusion plate 14 rotates into the rotating groove 11, the cleaning rod 17 in the notch of the rotating groove 11 is embedded in the elastic tentacle 15 and pushes out the debris wrapped inside it. Thanks to the deformation of the elastic tentacle 15, the friction force of the elastic tentacle 15 on the plate is guaranteed.

[0040] Reference Figure 6 The two ends of the cleaning rod 17 are set to be pointed, and a scraper 18 is provided on the surface of the middle part; the shape of the cleaning rod 17 is set to facilitate the insertion of the end of the cleaning rod 17 into the elastic tentacle 15, preventing the end of the cleaning rod 17 from pressing against the elastic tentacle 15 when the extrusion wheel 12 moves along the buffer groove 13, and a hanging piece is set in the middle position of the cleaning rod 17, which is beneficial to clean the debris in the elastic tentacle 15 more thoroughly.

[0041] Reference Figure 2 A chip removal pipe 19 is provided at the lower end of the chip removal hole 9, and the chip removal pipe 19 is connected to the collection shell 10. The outer circle of the chip removal pipe 19 is provided with a ring-shaped protrusion 20; by using an external vacuum cleaner, the vacuum cleaner pipe is plugged into the chip removal pipe 19, the debris is collected and prevented from spilling.

[0042] Embodiment 2:

[0043] Reference Figure 7 , compared with Example 1, as another embodiment of the present invention, the openings on both sides of the connecting block 3 are set in a wide-mouth shape; the shape of the connecting block 3 is set to facilitate embedding the disconnected end of the plate into the concave part of the connecting block 3.

[0044] Working principle: When the cutting machine 1 moves and cuts along the surface of the plate, the connecting block 3 is embedded in the cutting seam from one side of the plate. At this time, the cut surface of the plate is placed in the concave part of the connecting block 3, and the motor 4 is driven. The motor 4 drives the driven gear 6 to rotate through the driving gear 5, and the driven gear 6 drives the grinding wheel 7 to rotate. The grinding wheel 7 grinds the cut surface of the plate, and grinds the burrs and sharp corners at the edge of the port to make them smooth and round, thereby reducing the possibility of burrs and corners scratching and tearing some plastic film building materials after cutting, and reducing the possibility of sharp burrs scratching the hands of workers. At the same time, the plate can be cut while the cut surface is polished, so that the plate can be put into use after cutting, reducing the trouble of subsequent polishing.

[0045] The design of the shape of the grinding wheel 7 makes the grinding wheel 7 present a smooth and rounded surface after grinding the broken surface of the plate, which reduces the pain of the operator's hand being squeezed by the edge of the plate;

[0046] After grinding the edge of the plate, the debris splashes onto the surface of the plate at the break position. If the debris is not processed, the debris spreads to the surface of the plate. When the adjacent plates are stacked together, the debris particles will scratch and damage the surface of the plate. Therefore, by providing an extrusion bag 8, when the grinding wheel 7 is grinding the plate, the extrusion bag 8 on the grinding wheel 7 is indirectly squeezed on the surface of the plate, and at the same time, the gas in the extrusion bag 8 is bulged, and the debris on the surface of the plate is blown off to the position of the chip discharge hole 9, and then the debris falls into the collection shell 10 along the chip discharge hole 9;

[0047] After the plate is cut and broken, the plate at the broken part has a tendency to warp up, and this tendency will tilt and squeeze on the grinding wheel 7, increasing the friction of the relative movement between the plate and the connecting block 3, and at the same time increasing the power of the motor 4. For this reason, an extrusion wheel 12 is provided to squeeze and limit the broken opening of the plate, constrain the broken opening, reduce the warping amplitude of the broken opening of the plate, thereby reducing the tilting extrusion force of the plate on the connecting block 3, and ensuring the relative movement smoothness between the connecting block 3 and the broken opening of the plate;

[0048] The setting of the tilting direction of the rotating groove 11 and the extrusion wheel 12 makes it possible for the extrusion wheel 12 to push the plate toward the breaking opening during the relative movement between the plate and the connecting block 3, thereby reducing the tendency of the breaking openings to separate from each other and the tendency of the breaking openings of the plate to tilt, so that the grinding wheel 7 can grind and polish the edges and corners of the breaking opening more effectively; and the setting of the spring makes the extrusion wheel 12 adaptable to the extrusion restrictions on plates of different thicknesses;

[0049] By providing the squeezing plate 14, the squeezing surface of the squeezing wheel 12 on the plate is increased, and multiple rows of elastic tentacles 15 are provided on the squeezing plate 14 to increase the friction between the squeezing plate 14 and the plate, thereby reducing the possibility of slipping between the plate and the squeezing plate 14;

[0050] When the elastic tentacles 15 are pressed against the surface of the sheet, some debris on the surface of the sheet will enter the area enclosed between the elastic tentacles 15 and the pressing plate 14, causing the debris to adhere to the inside of the elastic tentacles 15, affecting the amount of extrusion deformation of the elastic tentacles 15, and reducing the extrusion friction of the elastic tentacles 15 on the sheet. To this end, by setting a cleaning mechanism, when the elastic tentacles 15 on the pressing plate 14 rotate into the rotating groove 11, the cleaning rods 17 in the notches of the rotating groove 11 are embedded in the elastic tentacles 15 and push out the debris wrapped therein. Thanks to the deformation of the elastic tentacles 15, the friction of the elastic tentacles 15 on the sheet is ensured.

[0051] The shape of the cleaning rod 17 facilitates the insertion of the end of the cleaning rod 17 into the elastic tentacle 15, preventing the end of the cleaning rod 17 from pressing against the elastic tentacle 15 when the extrusion wheel 12 moves along the buffer groove 13. The setting of a hanging piece in the middle of the cleaning rod 17 is beneficial for cleaning the debris in the elastic tentacle 15 more thoroughly. By using an external vacuum cleaner, the vacuum cleaner pipe is plugged into the chip discharge pipe 19 to collect the debris and prevent it from spilling out.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
