Description

Technical Field

[0001] The present invention relates to the field of cutting, and particularly to a grooving device for cement boards. Background Art

[0002] A cement board is a kind of building flat processed and produced mainly with cement. It is between gypsum board and stone. During the building process, in order to facilitate construction, the cement board is usually grooved by a device.

[0003] After retrieval, a Chinese patent application with the publication number of CN104493987A discloses a grooving device for cement boards, which includes a fixed seat. The fixed seat is a downward-opening fixed seat composed of a first L-shaped fixed seat and a second L-shaped fixed seat. One end of the second L-shaped fixed seat is inserted into one end of the first L-shaped fixed seat. The second L-shaped fixed seat is movable in the first L-shaped fixed seat through a lead screw. Telescopic rods are arranged on both sides of the downward-opening fixed seat. A number of identical grooving rollers are sleeved on the telescopic rods. The length after the telescopic rods are extended is equal to the length after the first L-shaped fixed seat and the second L-shaped fixed seat are unfolded. A handle is arranged on the fixed seat. The present invention can adjust according to the different widths of cement boards through the movable and inserted first L-shaped fixed seat and second L-shaped fixed seat to match them. At the same time, the telescopic rods also extend correspondingly to meet the width of the cement board, so that the work on the cement board can be completed at one time, reducing the workload and improving the work efficiency.

[0004] When the existing device grooves a cement board, it usually pushes the device to move on the cement board, so that the grooving mechanism grooves the cement board. However, when the grooving mechanism grooves the cement board, some cement board debris will get stuck on the grooving mechanism, thus affecting the grooving of the cement board. Summary of the Invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A grooving device for cement boards includes a base. Both sides of the base are rotatably connected with moving wheels through bearings. One side of the top of the base is bolted with a bracket, and the top of the bracket is bolted with a handle. One side of the top of the base is provided with an adjusting mechanism, and one side of the adjusting mechanism is provided with a support plate. One side of the bottom of the support plate is provided with a grooving mechanism, and one side of the grooving mechanism is provided with a cleaning mechanism. A transmission mechanism is arranged between the cleaning mechanism and the grooving mechanism.

[0007] Preferably, the adjusting mechanism includes a first motor, an adjusting frame, a lead screw, and an adjusting block. The bottom of the adjusting frame is bolted to the top of the base. The top and bottom of the lead screw are rotatably connected to opposite sides of the adjusting frame through bearings. The top of the adjusting frame is bolted to the first motor, and one end of the first motor is fixedly connected to the top of the lead screw. The adjusting block is slidably connected to the inner wall of the adjusting frame. A threaded hole is formed through the top of the adjusting block, and the threaded hole is threadedly connected to the lead screw. One side of the adjusting block is bolted to the support plate. Positioning ports are formed through opposite sides of the adjusting frame, and positioning blocks are slidably connected to the inner walls of the two positioning ports. One side of the two positioning blocks is bolted to the adjusting block.

[0008] Preferably, a positioning plate is bolted to one side of each of the two positioning blocks, and positioning holes are formed through one side of the tops of the two positioning plates. A positioning rod is slidably connected to the inner wall of the positioning hole, and the bottom of the positioning rod is bolted to the top of the base.

[0009] Preferably, the grooving mechanism includes side plates, a second motor, a rotating rod, a protective shell, and grooving knives. The top of the side plates is bolted to one side of the bottom of the support plate. The top of the protective shell is bolted to one side of the bottom of the support plate. The rotating rod is rotatably connected to one side of the protective shell and the side plates through bearings. One end of the rotating rod is bolted to the grooving knife. One side of the side plates is bolted to the second motor, and one end of the second motor is fixedly connected to the rotating rod.

[0010] Preferably, the cleaning mechanism includes a shaft rod, two backing plates, and two scrapers. The shaft rod is rotatably connected to the protective shell and the side plates through bearings. The two backing plates are bolted to both sides of the outer wall of the shaft rod. The scraper is bolted to the backing plate, and the scraper is made of an elastic material.

[0011] Preferably, the transmission mechanism includes a first gear, a second gear, a rotating shaft, two belt pulleys, and a belt. One end of the rotating shaft is rotatably connected to the side plates through bearings. The first gear is fixedly sleeved on the outer wall of the shaft rod, and the second gear is fixedly sleeved on the outer wall of the rotating shaft. The first gear meshes with the second gear. The two belt pulleys are respectively fixedly sleeved on the outer walls of the shaft rod and the rotating shaft, and the two belt pulleys are rotatably connected to the belt.

[0012] Preferably, a protective mechanism is arranged between one side of the top of the base and the cleaning mechanism, and the protective mechanism cooperates with the cleaning mechanism.

[0013] Preferably, the protection mechanism includes a support shaft, a push plate, a fixing plate and a protection plate. One side of the push plate is rotatably connected to a connecting shaft through a bearing. One end of the connecting shaft is bolted to the protection plate. A sliding opening is formed through one side of the protection plate. A slider is slidably connected to the inner wall of the sliding opening. One end of the support shaft is welded to the shaft rod. A convex portion is provided on the outer wall of the support shaft. A bushing is rotatably sleeved on the outer wall of the convex portion. Both ends of the push plate are hinged to the bushing and the slider respectively.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. By setting the grooving mechanism, transmission mechanism and cleaning mechanism, when grooving the cement board, move the device above the cement board. At this time, start the adjusting mechanism, and the adjusting mechanism will drive the grooving mechanism to move downward. At the same time, start the grooving mechanism. When the grooving mechanism contacts the cement board during the downward movement, the grooving mechanism will groove the cement board. During this period, drive the grooving mechanism to move through the moving wheels, so as to complete the grooving of the cement board. During this period, the transmission mechanism will rotate with the rotation of the grooving mechanism. The rotating shaft is rotated through the cooperation between the two belt pulleys and the belt. While the rotating shaft is rotating, it will drive the first gear to rotate synchronously. Through meshing, the second gear drives the shaft rod to rotate. At this time, the scraper will rotate with the rotation of the shaft rod. Since the scraper is made of elastic material, during the rotation of the scraper, it will contact the grooving tool, and the scraper will bend under the action of the grooving tool. At this time, the contact force between the scraper and the grooving tool will increase, so that the scraper can process the debris stuck on the grooving tool. Since the rotation directions of the grooving tool and the scraper are opposite, the reverse rotation of the scraper can effectively process the debris stuck on the grooving tool, prevent the debris from being stuck on the surface of the grooving tool and reduce the sharpness of the grooving mechanism, thus affecting the grooving of the cement board;

[0016] 2. By setting the cleaning mechanism and the protection mechanism, when the cleaning mechanism rotates under the action of the transmission mechanism, the support shaft will rotate synchronously with the rotation of the shaft rod. The push plate will push the protection plate to deflect reciprocally under the action of the convex portion and the bushing. When the protection plate deflects, it will block the debris generated during grooving, so as to protect the operator, prevent the debris from splashing due to the action of the grooving mechanism during grooving, and thus cause damage to the operator. In addition, when the adjusting mechanism drives the grooving mechanism to move downward, the slider will slide downward along the sliding opening. At this time, the deflection angle of the protection mechanism will change with the change of the position of the push plate, so as to effectively protect the grooving of the cement board.

A cleaning mechanism 23 is arranged on one side of the grooving mechanism 4, and a transmission mechanism 22 is arranged between the cleaning mechanism 23 and the grooving mechanism 4 to prevent debris from getting stuck on the surface of the grooving tool 18 and reducing the sharpness of the grooving mechanism 4, thereby affecting the grooving of the cement board.

[0026] On the basis of the above, the adjusting mechanism 7 includes a first motor 13, an adjusting frame 9, a lead screw 10 and an adjusting block 11. The bottom of the adjusting frame 9 is bolted to the top of the base 1. The top and bottom of the lead screw 10 are rotatably connected to opposite sides of the adjusting frame 9 through bearings. The top of the adjusting frame 9 is bolted to the first motor 13. One end of the first motor 13 is fixedly connected to the top of the lead screw 10. The adjusting block 11 is slidably connected to the inner wall of the adjusting frame 9. A threaded hole is formed through the top of the adjusting block 11, and the threaded hole is threadedly connected to the lead screw 10. One side of the adjusting block 11 is bolted to the support plate 6. Positioning ports 16 are formed through opposite sides of the adjusting frame 9. Positioning blocks 12 are slidably connected to the inner walls of the two positioning ports 16. One side of the two positioning blocks 12 is bolted to the adjusting block 11.

[0027] On the basis of the above, positioning plates 14 are bolted to one side of the two positioning blocks 12. Positioning holes are formed through one side of the tops of the two positioning plates 14. A positioning rod 15 is slidably connected to the inner wall of the positioning hole. The bottom of the positioning rod 15 is bolted to the top of the base 1.

[0028] On the basis of the above, the grooving mechanism 4 includes side plates 20, a second motor 21, a rotating rod 19, a protective shell 17 and grooving knives 18. The top of the side plates 20 is bolted to one side of the bottom of the support plate 6. The top of the protective shell 17 is bolted to one side of the bottom of the support plate 6. The rotating rod 19 is rotatably connected to one side of the protective shell 17 and the side plates 20 through bearings. One end of the rotating rod 19 is bolted to the grooving knife 18. One side of the side plates 20 is bolted to the second motor 21. One end of the second motor 21 is fixedly connected to the rotating rod 19.

[0029] On the basis of the above, the cleaning mechanism 23 includes a shaft rod 24, two backing plates 25 and two scraping knives 26. The shaft rod 24 is rotatably connected to the protective shell 17 and the side plates 20 through bearings. The two backing plates 25 are bolted to both sides of the outer wall of the shaft rod 24. The scraping knives 26 are bolted to the backing plates 25. The scraping knives 26 are made of elastic material.

[0030] On the basis described above, the transmission mechanism 22 includes a first gear 27, a second gear 28, a rotating shaft 29, two belt pulleys 30 and a belt 31. One end of the rotating shaft 29 is rotatably connected to the side plate 20 through a bearing. The first gear 27 is fixedly sleeved on the outer wall of the shaft rod 24, and the second gear 28 is fixedly sleeved on the outer wall of the rotating shaft 29. The first gear 27 meshes with the second gear 28. The two belt pulleys 30 are respectively fixedly sleeved on the outer walls of the shaft rod 24 and the rotating shaft 29, and a rotational connection is formed between the two belt pulleys 30 and the belt 31. The rotation of the rotating shaft 29 is achieved through the cooperation between the two belt pulleys 30 and the belt 31. While the rotating shaft 29 is rotating, it will drive the first gear 27 to rotate synchronously. Through meshing, the second gear 28 drives the shaft rod 24 to rotate. At this time, the scraper 26 will rotate along with the rotation of the shaft rod 24. Since the scraper 26 is made of an elastic material, the scraper 26 will contact the grooving tool 18 during rotation.

[0031] Embodiment 2. Refer to Figures 1-7 , a grooving device for cement boards. Compared with Embodiment 1, on the basis of Embodiment 1, a protection mechanism 8 is provided between one side of the top of the base 1 and the cleaning mechanism 23, and a cooperation is formed between the protection mechanism 8 and the cleaning mechanism 23.

[0032] On the basis described above, the protection mechanism 8 includes a support shaft 32, a push plate 35, a fixing plate 36 and a protection plate 38. One side of the push plate 35 is rotatably connected to a connecting shaft 37 through a bearing. One end of the connecting shaft 37 is bolted to the protection plate 38. A sliding opening 39 is formed through one side of the protection plate 38, and a slider 40 is slidably connected to the inner wall of the sliding opening 39. One end of the support shaft 32 is welded to the shaft rod 24. A convex portion 33 is provided on the outer wall of the support shaft 32, and a shaft sleeve 34 is rotatably sleeved on the outer wall of the convex portion 33. The two ends of the push plate 35 are respectively hinged to the shaft sleeve 34 and the slider 40. When the protection plate 38 deflects, it will block the debris generated during grooving, so as to protect the operator, prevent the debris from splashing due to the action of the grooving mechanism 4 during grooving, and thus cause damage to the operator. In addition, when the adjusting mechanism 7 drives the grooving mechanism 4 to move downward, the slider 40 will slide downward along the sliding opening 39. At this time, the deflection angle of the protection mechanism 8 will change with the change of the position of the push plate 35, so as to effectively protect the grooving of the cement board.

[0033] In summary, by means of the above technical solutions of the present invention: when grooving a cement board, the device is moved above the cement board. At this time, the adjusting mechanism 7 is started, and the adjusting mechanism 7 drives the grooving mechanism 4 to move downward. At the same time, the grooving mechanism 4 is started. When the grooving mechanism 4 contacts the cement board during the downward movement, the grooving mechanism 4 grooves the cement board. During this period, the grooving mechanism 4 is driven to move by the moving wheels 5, thereby completing the grooving of the cement board. During this period, the transmission mechanism 22 rotates with the rotation of the grooving mechanism 4. The rotating shaft 29 is rotated through the cooperation between the two belt pulleys 30 and the belt 31. While the rotating shaft 29 is rotating, it drives the first gear 27 to rotate synchronously. Through meshing, the second gear 28 drives the shaft rod 24 to rotate. At this time, the scraper 26 rotates with the rotation of the shaft rod 24. Since the scraper 26 is made of an elastic material, during the rotation of the scraper 26, it contacts the grooving cutter 18, and the scraper 26 bends under the action of the grooving cutter 18. At this time, the contact force between the scraper 26 and the grooving cutter 18 increases, so that the debris stuck on the grooving cutter 18 can be processed by the scraper 26. Since the rotation directions of the grooving cutter 18 and the scraper 26 are opposite, the reverse rotation of the scraper 26 can effectively process the debris stuck on the grooving cutter 18, preventing the debris from being stuck on the surface of the grooving cutter 18 and reducing the sharpness of the grooving mechanism 4, thereby affecting the grooving of the cement board. When the cleaning mechanism 23 rotates under the action of the transmission mechanism 22, the support shaft 32 rotates synchronously with the rotation of the shaft rod 24. The push plate 35 pushes the protective plate 38 to deflect reciprocally under the action of the protrusion 33 and the bushing 34. When the protective plate 38 deflects, it blocks the debris generated during grooving, so as to protect the operator, preventing the debris from splashing due to the action of the grooving mechanism 4 during grooving and causing injury to the operator. In addition, when the adjusting mechanism 7 drives the grooving mechanism 4 to move downward, the slider 40 slides downward along the sliding opening 39. At this time, the deflection angle of the protection mechanism 8 changes with the change of the position of the push plate 35, so as to effectively protect the grooving of the cement board.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
