Description

Technical Field

[0001] The present invention relates to the technical field of building formwork processing, and particularly to a cutting device for building formwork production. Background Art

[0002] During the production and processing of building formwork, a cutting device is often required to cut the logs of building formwork, so as to cut the logs of building formwork into required sizes and shapes.

[0003] The utility model with Chinese patent number CN211104496U discloses a log cutting device for building formwork production, including a base, a box body frame, a cutting mechanism, a cutting disc assembly, a fixture and a cleaning device. The water sprayed by the cleaning device can clean the wood chips generated during the cutting process of the log by the cutting disc assembly, and at the same time, it can also play a role in cooling and dissipating heat for the cutting disc.

[0004] The limiting frame in the cutting disc assembly can protect the cutting disc. As the cutting disc rotates, the water sprayed by the cleaning device and the generated wood chips will enter the limiting frame under the inertial action of the rotation of the cutting disc and adhere to the inner wall, resulting in difficult cleaning. The staff still need to remove the limiting frame for cleaning and then reinstall it, which is rather inconvenient. Summary of the Invention

[0005] The purpose of the present invention is to solve the following disadvantages in the prior art: as the cutting disc rotates, the water sprayed by the cleaning device and the generated wood chips will enter the limiting frame under the inertial action of the rotation of the cutting disc and adhere to the inner wall, resulting in difficult cleaning. The staff still need to remove the limiting frame for cleaning and then reinstall it, which is rather inconvenient. Therefore, a cutting device for building formwork production is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A cutting device for building formwork production, including a protective cover. A rotating rod is horizontally and rotatably installed in the protective cover. A cutting disc is fixedly sleeved on the rotating rod. One end of the rotating rod passes through the protective cover and is rotatably sleeved with a rotating plate through a rotating component. The rotating plate is controlled to reciprocally rotate through a driving component;

[0008] The surface of the protective cover is provided with an arc-shaped sliding opening. At the top end of the rotating plate, a sliding plate configured to slide within the sliding opening is fixedly installed on the surface. One end of the sliding plate located inside the protective cover is fixedly installed with a scraping plate through a first spring rod. On the surface of one end of the sliding plate located inside the protective cover, installation openings are symmetrically and horizontally opened. An installation rod is horizontally and fixedly installed within the installation openings. A scraping rod is slidably sleeved on the installation rod. A telescopic spring is sleeved on the installation rod, and the two ends of the telescopic spring are respectively fixedly connected to the inner wall of the installation opening and the surface of the scraping rod. The surfaces of the scraping plate and the two scraping rods are all in sliding contact with the inner wall of the protective cover.

[0009] As a preferred solution, the rotating component includes a rotating ring and a connecting rod rotatably sleeved on the rotating rod. The two ends of the connecting rod are respectively fixedly connected to the bottom end of the rotating plate and the outer ring wall of the rotating ring.

[0010] As a preferred solution, a servo motor is fixedly installed on the surface of the protective cover. One end of the rotating rod passes through the protective cover and is fixedly connected to the output shaft of the servo motor.

[0011] As a preferred solution, the driving component includes a first gear, a second gear, and a resisting rod fixedly installed on the surface of the second gear. The first gear is fixedly sleeved on one end of the rotating rod. The second gear is rotatably installed on the protective cover through an installation component and is meshed with the first gear. A resisting opening is vertically opened on the surface of the rotating plate. One end of the resisting rod is slidably configured within the resisting opening, and its surface is in sliding contact with the inner wall of the resisting opening.

[0012] As a preferred solution, an L-shaped placement plate is fixedly installed on the side wall of the sliding plate located inside the protective cover. A second spring rod is fixedly installed on the surface of the placement plate. One end of the second spring rod is fixedly installed with a trapezoidal locking block. A trapezoidal first pressing block is fixedly sleeved on the first spring rod. The inclined surfaces of the first pressing block and the locking block are arranged face to face, and the length of the locking block is greater than the length of the first pressing block.

[0013] As a preferred solution, a triangular second pressing block is fixedly installed at the top end of the scraping rod. Two connecting rods are symmetrically and vertically fixedly installed on the lower surface of the scraping plate. A trapezoidal third pressing block is fixedly installed at the bottom end of the connecting rods. The inclined surfaces of the two second pressing blocks are respectively arranged face to face with the inclined surfaces of the two third pressing blocks.

[0014] As a preferred solution, an L-shaped push rod and a triangular convex platform are fixedly installed on the inner wall of the protective cover. The push rod is used to push the locking block to move, and the convex platform is used to control the contraction of the first spring rod.

[0015] As a preferred solution, the two ends of the rotating rod passing through the protective cover are respectively provided with reciprocating threads with opposite thread directions. Both ends of the rotating rod are threadedly sleeved with sliding seats. The two sliding seats are symmetrically arranged. A pair of sockets are horizontally opened on the front and rear surfaces of the protective cover. The two pairs of sockets are symmetrically arranged. Two insertion blocks are fixedly installed on the surface of the sliding seat through two third spring rods. Multiple insertion blocks are respectively slidably inserted into multiple sockets.

[0016] As a preferred solution, the installation component includes a fixing plate fixedly installed on the surface of the protective cover and a rotating shaft rotatably installed on the surface of the fixing plate. An annular groove is opened on the surface of the second gear. One end of the rotating shaft is slidably installed in the annular groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When the cutting disc is rotating, under the action of the driving component at this time, the rotating rod will rotate reciprocally. Then the scraping plate and the two scraping rods located inside the protective cover will rotate along with the rotating rod, thereby scraping the water and wood chips adhering to the inner wall of the protective cover out of the protective cover, achieving the cleaning effect, and there is no need for the staff to remove the protective cover for cleaning;

[0019] With the cooperation among the push rod, the convex platform, the locking block, the first pressing block, the second pressing block and the third pressing block, the scraping plate and the two scraping rods will not always abut against the inner wall of the protective cover, but will intermittently abut against the inner wall of the protective cover. Therefore, on the premise of ensuring that the scraping plate and the two scraping rods can clean the inner wall of the protective cover, the wear of the scraping plate and the two scraping rods is reduced, and their service life is improved;

[0020] As the cutting disc rotates, the two pairs of insertion blocks will also move reciprocally in the horizontal direction. When the two pairs of insertion blocks abut against the surface of the cutting disc, since the cutting disc is in a rotating state, the two pairs of insertion blocks can clean the water and wood chips on the surface of the cutting disc. At the same time, when the two pairs of insertion blocks abut against the surface of the cutting disc, the opening of the protective cover is basically in a closed state at this time, so that the amount of water and wood chips entering the protective cover from the opening can be reduced;

[0021] Since the two sliding seats are symmetrically arranged and the reciprocating thread directions at both ends of the rotating rod are opposite, when the two pairs of insertion blocks both abut against the cutting disc, a certain clamping and limiting effect can be achieved, reducing the amplitude of jitter during the cutting process of the cutting disc, and improving the cutting accuracy and the stability of the cutting process.

Embodiment

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] Refer to Figures 1-10, A cutting device for building formwork production, including a protective cover 1. Inside the protective cover 1, a rotating rod 2 is horizontally rotatably installed. A cutting disc 3 is fixedly sleeved on the rotating rod 2. One end of the rotating rod 2 passes through the protective cover 1 and is rotatably sleeved with a rotating plate 4 through a rotating component. The rotating component includes a rotating ring rotatably sleeved on the rotating rod 2 and a connecting rod. The two ends of the connecting rod are respectively fixedly connected to the bottom end of the rotating plate 4 and the outer wall of the rotating ring. The rotating plate 4 is controlled to reciprocally rotate through a driving component. The driving component includes a first gear 13, a second gear 14, and a resisting rod 15 fixedly installed on the surface of the second gear 14. The first gear 13 is fixedly sleeved on one end of the rotating rod 2. The second gear 14 is rotatably installed on the protective cover 1 through an installation component and is meshed with the first gear 13. The installation component includes a fixing plate 27 fixedly installed on the surface of the protective cover 1 and a rotating shaft 28 rotatably installed on the surface of the fixing plate 27. An annular groove 29 is opened on the surface of the second gear 14. One end of the rotating shaft 28 is slidably installed in the annular groove 29. A resisting port 16 is vertically opened on the surface of the rotating plate 4. One end of the resisting rod 15 is slidably arranged in the resisting port 16, and its surface is in sliding contact with the wall of the resisting port 16. A servo motor 12 is fixedly installed on the surface of the protective cover 1. One end of the rotating rod 2 passes through the protective cover 1 and is fixedly connected to the output shaft of the servo motor 12;

[0035] An arc-shaped sliding port 5 is opened on the surface of the protective cover 1. A sliding plate 6 fixedly installed on the surface at the top end of the rotating plate 4 is slidably arranged in the sliding port 5. One end of the sliding plate 6 located inside the protective cover 1 is fixedly installed with a scraping plate 8 through a first spring rod 7 on the upper surface. Symmetrically horizontal installation ports are opened on one end surface of the sliding plate 6 located inside the protective cover 1. An installation rod 9 is horizontally fixedly installed in the installation port. A scraping rod 10 is slidably sleeved on the installation rod 9. A telescopic spring 11 is sleeved on the installation rod 9. The two ends of the telescopic spring 11 are respectively fixedly connected to the wall of the installation port and the surface of the scraping rod 10. The surfaces of the scraping plate 8 and the two scraping rods 10 are all in sliding contact with the inner wall of the protective cover 1;

[0036] Start the servo motor 12. At this time, the output shaft of the servo motor 12 will drive the rotating rod 2 and the cutting disc 3 to rotate. In this process, the first gear 13 fixedly sleeved on the rotating rod 2 will also rotate, so that the second gear 14 meshed with the first gear 13 will rotate together. The resisting rod 15 fixedly installed on the surface of the second gear 14 will move in the resisting port 16, and the rotating plate 4 will perform a reciprocating rotation under the acting force of the resisting rod 15 pressing against it;

[0037] During the rotation of the rotating plate 4, the scraping plate 8 and the two scraping rods 10 will all be in sliding contact with the inner wall of the protective cover 1, so as to scrape off the water stains and wood chips attached to the inner wall of the protective cover 1, achieving the cleaning effect, and there is no need for the staff to remove the protective cover 1 for cleaning.

[0038] On the side wall of the skateboard 6 located inside the protective cover 1, an L-shaped placement plate is fixedly installed. On the surface of the placement plate, a second spring rod 17 is fixedly installed. At one end of the second spring rod 17, a trapezoidal locking block 18 is fixedly installed. A trapezoidal first pressing block 19 is fixedly sleeved on the first spring rod 7. The inclined surface of the first pressing block 19 is arranged face to face with the inclined surface of the locking block 18. The length of the locking block 18 is greater than the length of the first pressing block 19. At the top end of the scraping rod 10, a triangular second pressing block 20 is fixedly installed. On the lower surface of the scraping plate 8, two connecting rods are symmetrically and perpendicularly fixedly installed. At the bottom end of the connecting rods, a trapezoidal third pressing block 21 is fixedly installed. The inclined surfaces of the two second pressing blocks 20 are respectively arranged face to face with the inclined surfaces of the two third pressing blocks 21;

[0039] On the inner wall of the protective cover 1, an L-shaped push rod 22 and a triangular boss 23 are fixedly installed. The push rod 22 is used to push the locking block 18 to move, and the boss 23 is used to control the contraction of the first spring rod 7;

[0040] When the rotating plate 4 drives the scraping plate 8 and the two scraping rods 10 that are in contact with the inner wall of the protective cover 1 to rotate to the bottommost position in the direction close to the boss 23, at this time, the side wall of the scraping plate 8 will slide into contact with the inclined surface of the boss 23. Then, under the action of pressing, the first spring rod 7 will contract. The first pressing block 19 fixedly sleeved on the first spring rod 7 will move along with the contraction of the first spring rod 7, and its inclined surface will slide into contact with the inclined surface of the locking block 18. Then, under the action of the inclined surface pressing, the second spring rod 17 will contract until the first pressing block 19 moves to a position where its inclined surface no longer contacts the inclined surface of the locking block 18. At this time, the pressing force applied to the locking block 18 disappears, and the locking block 18 will quickly move back to its original position under the elastic potential energy of the second spring rod 17 and form a clamping lock with the first pressing block 19. At this time, the first spring rod 7 will be locked, and the scraping plate 8 will no longer contact the inside of the protective cover 1;

[0041] During the contraction of the first spring rod 7 and the movement of the scraping plate 8, the inclined surfaces of the two second pressing blocks 20 will respectively slide into contact with the inclined surfaces of the two third pressing blocks 21. Then, under the action of the inclined surface pressing, the two scraping rods 10 will also move closer to each other in the horizontal direction. At this time, the two scraping rods 10 will no longer abut against the inner wall of the protective cover 1. Then, when the rotating plate 4 drives the sliding plate 6, the scraping plate 8 and the two scraping rods 10 to rotate in the direction away from the boss 23, since the scraping plate 8 and the two scraping rods 10 do not abut against the inner wall of the protective cover 1, they will not clean the inner wall of the protective cover 1. Only when it rotates to the other bottommost position, at this time, the end of the push rod 22 will abut against the locking block 18 and push the locking block 18 to move. The second spring rod 17 will contract under the action of the thrust, and then the locking block 18 will no longer contact the first pressing block 19, the blocking of the first pressing block 19 is released, and the locking of the first spring rod 7 is also released. The scraping plate 8 will quickly reset under the elastic potential energy of the first spring rod 7, and thus will abut against the inner wall of the protective cover 1 again. With the reset of the scraping plate 8, the two third pressing blocks 21 will also reset together, so that the pressing force on the two second pressing blocks 20 disappears. The two scraping rods 10 will quickly move and reset under the elastic potential energy of the two telescopic springs 11 and will abut against the inner wall of the protective cover 1 again;

[0042] When the rotating plate 4 drives the scraping plate 8 and the two scraping rods 10 that abut against the inner wall of the protective cover 1 to rotate in the direction close to the boss 23, the scraping plate 8 and the two scraping rods 10 will scrape the water stains and wood chips attached to the inner wall of the protective cover 1 out of the protective cover 1. That is, the scraping plate 8 and the two scraping rods 10 will not always abut against the inner wall of the protective cover 1, but will intermittently abut against the inner wall of the protective cover 1. Thus, on the premise of ensuring that the scraping plate 8 and the two scraping rods 10 can clean the inner wall of the protective cover 1, the wear of the scraping plate 8 and the two scraping rods 10 is reduced, and their service life is improved.

[0043] The two ends of the rotating rod 2 passing through the protective cover 1 are respectively provided with reciprocating threads with opposite thread directions. Both ends of the rotating rod 2 are threadedly sleeved with sliding seats 24. The two sliding seats 24 are symmetrically arranged. A pair of sockets are horizontally opened on the front and back surfaces of the protective cover 1. The two pairs of sockets are symmetrically arranged. Two insertion blocks 26 are fixedly installed on the surface of the sliding seat 24 through two third spring rods 25. Multiple insertion blocks 26 are respectively slidably inserted into multiple sockets;

[0044] As the cutting disc 3 rotates, the two sliding seats 24 threadedly sleeved on the rotating rod 2 will move relatively in the horizontal direction. During the movement, the two pairs of insertion blocks 26 will intermittently abut against the surface of the cutting disc 3. When the two pairs of insertion blocks 26 abut against the surface of the cutting disc 3, since the cutting disc 3 is in a rotating state, the two pairs of insertion blocks 26 can scrape off the water and wood chips on the surface of the cutting disc 3. At the same time, when the two pairs of insertion blocks 26 abut against the surface of the cutting disc 3, the opening of the protective cover 1 is basically in a closed state, so as to reduce the amount of water and wood chips entering the protective cover 1 from the opening.

[0045] And when both pairs of insertion blocks 26 abut against the cutting disc 3, it can play a certain clamping and limiting effect on the cutting disc 3, reduce the amplitude of vibration during the cutting process of the cutting disc 3, and improve the cutting accuracy and the stability of the cutting process.

[0046] In the present invention, when the cutting disc 3 is rotating, under the action of the driving component, the rotating plate 4 will rotate reciprocally, the sliding plate 6 will rotate reciprocally in the sliding opening 5, and the scraping plate 8 and the two scraping rods 10 located inside the protective cover 1 will scrape off the water and wood chips adhering to the inner wall of the protective cover 1, so as to achieve the cleaning effect, without the need for staff to remove the protective cover 1 for cleaning, reducing the labor burden of the staff.

[0047] 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
