Description

Technical Field

[0001] This application relates to the field of cutting technology, specifically a construction cutting device. Background Technology

[0002] In construction engineering, there are many processes that require cutting and processing materials, and cutting equipment is needed to cut the materials into dimensions that meet the construction requirements.

[0003] An existing patent (publication number: CN221808974U) discloses a construction material cutting device, which includes a transmission structure. When using the device, the user can start a second motor to drive the transmission structure, which in turn pushes the material to be cut. This structure enables the device to achieve a partially automated cutting process, reducing the labor intensity of the operator and improving work efficiency. Furthermore, the movable plate is replaceable, allowing the device to adapt to materials of different sizes and shapes. Moreover, the motor-driven structure makes the cutting process more stable, maintaining a consistent cutting speed and pressure, thus improving cutting quality and accuracy. During cutting, the ventilation holes on the saw blade cover can dissipate heat from the saw blade, reducing its cutting temperature and minimizing the possibility of damage caused by overheating.

[0004] The above solution cannot hold and fix the material during cutting, which causes the material to shift during cutting and affects the accuracy of the material cutting dimensions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a construction cutting device that can stably hold and fix both sides of the material during cutting, preventing displacement of the material during cutting and improving the accuracy of material cutting dimensions. This solves the problem that the material cannot be held and fixed during cutting, which leads to displacement of the material and affects the accuracy of material cutting dimensions.

[0006] To achieve the aforementioned goal of stably holding and fixing both sides of the material during cutting, preventing displacement and improving the accuracy of material cutting dimensions, this application provides the following technical solution: a construction cutting device, including a cutting panel, a fixing frame at the top of the cutting panel, a hydraulic rod at the top of the inner side of the fixing frame, a cutting mechanism at the bottom of the hydraulic rod via a connecting frame, a through-cutting groove in the middle of the cutting panel located below the cutting mechanism, two pressing wheels on both sides of the cutting mechanism, the pressing wheels being rotatably mounted on the bottom of a telescopic rod via a rotating frame, the top of the telescopic rod being mounted on the top of the inner side of the fixing frame via a fixing rod, a spring inside the telescopic rod, one end of the spring being mounted on one end of the inner wall of the telescopic rod's outer tube, and the other end of the spring being mounted on one end of the telescopic rod's inner tube.

[0007] A motor is mounted on the bottom of the cutting panel via a fixing block. One end of the motor is equipped with a threaded rod. One end of the threaded rod is rotatably mounted on the bottom of the cutting panel away from the motor via a fixing plate. The outer surface of the middle part of the threaded rod is threaded to the inner wall of the middle part of the connecting plate. A support frame is mounted on the top of the connecting plate, and a push plate is mounted on the top of the support frame.

[0008] The above solution applies a downward thrust to the inner telescopic rod of the telescopic rod via a spring, which in turn applies a downward thrust to the pressing wheel, causing the pressing wheel to press down on the top of the material. This achieves stable pressure and fixation of both sides of the material during cutting, preventing displacement and improving the accuracy of the material cutting dimensions.

[0009] Furthermore, two limiting rods are slidably provided on the inner walls of both ends of the connecting plate, and the two limiting rods are set on both sides of the bottom of the cutting panel through a fixing plate.

[0010] By using the above method, the angle of the connecting plate can be fixed when it moves by sliding the inner walls of both ends of the connecting plate on the outer surface of the middle part of the two limiting rods, thereby improving the stability of the connecting plate when it moves.

[0011] Furthermore, the support frame is U-shaped, and the bottom of the inner side of the support frame is located below the cutting panel.

[0012] With the above solution, the U-shaped arrangement of the support frame ensures that the cutting blade of the cutting mechanism will cut the moving support frame when cutting the material in the cutting groove.

[0013] Furthermore, two push plates are provided at both ends of the top of the support frame, and the gap between the two push plates is greater than the thickness of the cutting blade of the cutting mechanism.

[0014] The above scheme uses two push plates to move the material and push it to the cutting mechanism for cutting. The gap between the two push plates prevents the cutting mechanism from cutting the push plates, allowing the two push plates to push the material to be completely cut by the cutting mechanism.

[0015] Furthermore, two lifting platforms are slidably disposed on the top of the cutting panel, and the outer surface of the top of the two lifting platforms is connected to the sliding rod of the middle outer surface of the two pressing wheels. The outer surface of the top of one end of the lifting platform is inclined.

[0016] By using the above method, the outer surface of the middle part of the pressing roller rolls on the inclined outer surface at the top of one end of the lifting platform, which allows the pressing roller to move upward through the lifting platform, increasing the height of the pressing roller. In turn, the pressing roller can be moved to the top of the material to be cut through the lifting platform to press the material.

[0017] Furthermore, a slider is provided at the bottom of the lifting platform, and the outer surface of the middle part of the slider is slidably disposed in the inner wall of the middle part of the slide groove, which is opened inside the middle side of the cutting panel.

[0018] The above method, by having the slider slide on the inner wall of the middle of the chute, can fix the trajectory of the lifting platform and improve the stability of the lifting platform during movement.

[0019] Furthermore, the bottom of the inner wall of the chute is provided with multiple discharge ports that run vertically through each other.

[0020] The above scheme allows cutting debris that splashes into the chute to be discharged through the discharge port.

[0021] Furthermore, a linkage frame is provided on one side of the telescopic rod. The linkage frame is U-shaped, and its two ends are located on one side of the telescopic inner rod of the two telescopic rods.

[0022] With the above solution, pulling the linkage frame upwards can retract the two telescopic rods, thereby raising the height of the two pressing rollers, allowing the push plate and lifting platform to pass under the pressing rollers and return to the cutting starting point.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This construction cutting device uses a spring to apply a downward thrust to the inner telescopic rod of a telescopic rod, which in turn applies a downward thrust to the pressing wheel, causing the pressing wheel to press down on the top of the material. This achieves stable pressing and fixing of the material on both sides during cutting, preventing displacement of the material during cutting and improving the accuracy of the material cutting dimensions.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The construction cutting device in this embodiment includes a cutting panel 1, a fixing frame 2 on the top of the cutting panel 1, a hydraulic rod 3 on the top of the inner side of the fixing frame 2, a cutting mechanism 4 on the bottom of the hydraulic rod 3 via a connecting frame, a cutting groove 5 extending vertically through the middle of the cutting panel 1, the cutting groove 5 being located below the cutting mechanism 4, two pressing wheels 7 on both sides of the cutting mechanism 4, the pressing wheels 7 being rotatably mounted on the bottom of a telescopic rod 6 via a rotating frame, the top of the telescopic rod 6 being mounted on the top of the inner side of the fixing frame 2 via a fixing rod, a spring 8 inside the telescopic rod 6, one end of the spring 8 being mounted on one end of the inner wall of the telescopic outer tube of the telescopic rod 6, and the other end of the spring 8 being mounted on one end of the telescopic inner rod of the telescopic rod 6.

[0034] Please see Figure 2 , Figure 3 and Figure 4A motor 9 is mounted on the bottom of the cutting panel 1 via a fixing block. A threaded rod 10 is mounted on one end of the motor 9. One end of the threaded rod 10 is rotatably mounted on the bottom of the cutting panel 1 away from the motor 9 via a fixing plate. The outer surface of the middle part of the threaded rod 10 is threadedly connected to the inner wall of the middle part of the connecting plate 11. A support frame 12 is mounted on the top of the connecting plate 11. A push plate 13 is mounted on the top of the support frame 12.

[0035] Please see Figure 3 and Figure 4 Two limiting rods 14 are slidably provided on the inner walls of both ends of the connecting plate 11. The two limiting rods 14 are set on both sides of the bottom of the cutting panel 1 through the fixing plate. The connecting plate 11 slides on the outer surface of the middle part of the two limiting rods 14 through the inner walls of both ends of the connecting plate 11, which can fix the angle when the connecting plate 11 moves and improve the stability of the connecting plate 11 when it moves.

[0036] Please see Figure 4 The support frame 12 is U-shaped, and the bottom of the inner side of the support frame 12 is located below the cutting panel 1. Due to the U-shaped arrangement of the support frame 12, the cutting blade of the cutting mechanism 4 can cut the moving support frame 12 when cutting the material in the cutting groove 5.

[0037] Please see Figure 1 , Figure 2 and Figure 4 The support frame 12 has two push plates 13 at both ends of its top. The gap between the two push plates 13 is greater than the thickness of the cutting blade of the cutting mechanism 4. The material can be moved by the two push plates 13 and pushed to the cutting mechanism 4 for cutting. The gap between the two push plates 13 can prevent the cutting mechanism 4 from cutting the push plates 13, so that the two push plates 13 can push the material to be completely cut by the cutting mechanism 4.

[0038] Please see Figure 2 , Figure 3 and Figure 4 Two lifting platforms 17 are slidably arranged on the top of the cutting panel 1. The outer surface of the top of the two lifting platforms 17 is connected to the sliding rod of the middle outer surface of the two pressing rollers 7. The outer surface of the top of one end of the lifting platform 17 is inclined. By rolling the middle outer surface of the pressing roller 7 on the inclined outer surface of the top of one end of the lifting platform 17, the pressing roller 7 can be moved upward through the lifting platform 17, increasing the height of the pressing roller 7. Then, the pressing roller 7 can be moved to the top of the material to be cut to press the material.

[0039] Please see Figure 2 and Figure 4The bottom of the lifting platform 17 is provided with a slider 16. The outer surface of the middle part of the slider 16 is slidably disposed in the inner wall of the middle part of the slide groove 15. The slide groove 15 is opened inside the middle part of the cutting panel 1. By sliding the slider 16 in the inner wall of the middle part of the slide groove 15, the trajectory of the lifting platform 17 can be fixed, thereby improving the stability of the lifting platform 17 when it moves.

[0040] Please see Figure 2 and Figure 5 The bottom of the inner wall of the chute 15 is provided with multiple vertically penetrating discharge ports 18, which allow cutting debris that splashes into the chute 15 to be discharged through the discharge ports 18.

[0041] Please see Figure 1 , Figure 2 and Figure 4 A linkage frame 19 is provided on one side of the telescopic rod 6. The linkage frame 19 is U-shaped. Both ends of the linkage frame 19 are located on one side of the telescopic inner rod of the two telescopic rods 6. By pulling the linkage frame 19 upward, the two telescopic rods 6 can be retracted, thereby raising the height of the two pressing wheels 7, so that the push plate 13 and the lifting platform 17 can pass under the pressing wheels 7 and return to the cutting starting point.

[0042] In this embodiment, a construction cutting device applies a downward thrust to the inner telescopic rod of the telescopic rod 6 via the spring 8, which in turn applies a downward thrust to the pressing wheel 7. This causes the pressing wheel 7 to press down on the top of the material, achieving stable pressure and fixation of both sides of the material during cutting. This prevents the material from shifting during cutting and improves the accuracy of the material cutting dimensions.

[0043] The working principle of the above embodiment is as follows: The material to be cut is placed between the push plate 13 and the lifting platform 17. The hydraulic rod 3 operates, pushing the cutting mechanism 4 downward, so that the cutting blade of the cutting mechanism 4 is inserted into the cutting groove 5. The cutting mechanism 4 operates, causing the cutting blade of the cutting mechanism 4 to rotate. The motor 9 operates, driving the threaded rod 10 to rotate, so that the connecting plate 11 drives the push plate 13 to move towards the cutting mechanism 4 through the support frame 12. When the push plate 13 pushes the material, it will drive the lifting platform 17 to move, so that the slider 16 slides in the slide groove 15. When the lifting platform 17 moves, the inclined outer surface of one end of the lifting platform 17 will contact the middle outer surface of the pressing wheel 7, so that the lifting platform 17 pushes the pressing wheel 7 upward through the inclined outer surface, so that the telescopic rod 6 begins to retract, squeezing the spring 8. Through the continuous movement of the lifting platform 17, the pressing wheel 7 moves past the lifting platform 17 to the top of the material between the lifting platform 17 and the push plate 13. Spring 8 releases its thrust, and the telescopic rod 6 applies a downward thrust to the pressing wheel 7, causing the pressing wheel 7 to press firmly against the top of the material, thus holding the material. When the push plate 13 pushes the material, the cutting mechanism 4 cuts the material, and the pressing wheel 7 rolls on top of the material until the push plate 13 pushes the material past the cutting mechanism 4, allowing the cutting mechanism 4 to completely cut the material. When the cutting debris splashes into the chute 15, the slider 16 slides in the chute 15, pushing the debris in the chute 15 and pushing it out of the discharge port 18. When it is necessary to reset the push plate 13 and the lifting platform 17, the linkage frame 19 is pulled upward, causing the telescopic rod 6 to retract, which drives the pressing wheel 7 to move upward. The motor 9 works, causing the threaded rod 10 to drive the connecting plate 11 to move, thereby driving the push plate 13 to pass under the pressing wheel 7 for reset, and pushing the lifting platform 17 to pass under the pressing wheel 7 for reset.
