Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a cutting device for building decoration. Background Art

[0002] Building decoration, also known as building decoration and fitting-up project, is an important link in the construction industry. Building decorative boards, as a kind of decorative materials widely used in the fields of home, building and industry, are usually used for decoration, finishing or protection purposes. After retrieval, a patent with the Chinese patent publication number CN220094714U discloses a cutting device for decorative boards used in building decoration. Although the distance between the cutting blade and the support plate can be adjusted by setting a movable cutting blade during use of this device, so as to meet the cutting requirements of different widths of different decorative boards, this device cannot ensure the stability of the forward feeding of the decorative board during cutting. When the feeding of the board is inclined, it will cause the cutting direction of the board to deviate, affecting the cutting accuracy. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a cutting device for building decoration, which solves the problems put forward in the background art.

[0004] The solution of the utility model to the above technical problems is as follows:

[0005] A cutting device for building decoration, including a bracket, a main shaft, bearings and a fixing plate. Bearings are installed at both ends of the bracket, the main shaft is inserted into the bearings, and the main shaft is welded and fixed with the bearings. A keyway is opened on the main shaft. A spline sleeve is installed on the main shaft between the bearings by keyway limiting. A bushing is sleeved outside the spline sleeve, and a roller is installed outside the bushing. The bushing and the spline sleeve are an integral body. A handle is welded at the top of the bracket, and the included angle between the handle and the horizontal plane is fifteen degrees. A fixing plate is welded at one end of the bracket close to the handle. A fixing frame is welded on the lower surface of the fixing plate. A threaded rod is clamped on the lower surface of the fixing plate through the fixing frame, and a blade is installed on the threaded rod.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, the roller is a rubber ring, and a groove is opened on the bushing, and the roller is limit installed in the groove of the bushing.

[0008] The beneficial effect of adopting the above further scheme is:

[0009] The rubber roller provides high friction, which helps the stability of the equipment on the sheet. The elasticity and grip of the rubber enable the roller to better contact the surface of the sheet, preventing slipping or deviation, thus improving the cutting accuracy.

[0010] Furthermore, through holes are provided on the spline sleeve, and bolts are installed in the through holes. The spline sleeve is locked and fixed on the main shaft by the bolts.

[0011] The beneficial effect of adopting the above further scheme is:

[0012] In some cases, it may be necessary to adjust the relative position between the spline sleeve and the main shaft according to the actual working conditions. Through the bolt connection, it can be conveniently achieved by loosening the bolts, and this adjustment can be relatively easily realized, improving the maintainability and flexibility of the equipment to meet different usage requirements.

[0013] Furthermore, threads are provided at both ends of the threaded rod, and nuts are installed on the threaded rod through the threads. The threaded rod is locked on the fixing frame by the nuts.

[0014] The beneficial effect of adopting the above further scheme is:

[0015] By locking the threaded rod on the fixing frame with nuts, it can ensure that the blade is firmly installed on the equipment, preventing the blade from loosening or displacing during use. This stable fixing method ensures the accuracy and safety during the cutting process.

[0016] Furthermore, the blade is a cutting knife or a hob.

[0017] The beneficial effect of adopting the above further scheme is:

[0018] Supporting two types of blades (cutting knives and hobs) enables the equipment to be used in different cutting tasks without the need to replace tools or equipment. This versatility makes the equipment more general and able to adapt to various cutting requirements, thus enhancing the comprehensive utilization rate of the equipment. Cutting knives are usually used for fine cutting tasks, such as cutting thin sheets or making precise line divisions. Hobs are suitable for large-area cutting, such as cutting thick sheets or large pieces of materials. Hobs can provide stable cutting force and are suitable for more rugged cutting tasks, such as the division of large-area sheets.

[0019] Furthermore, when the blade is a cutting knife, the fixing hole of the blade is rectangular, and a pin block adapted to the size of the fixing hole is provided in the middle section of the threaded rod.

[0020] The beneficial effect of adopting the above further scheme is:

[0021] The rectangular fixing hole cooperates with the pin block on the threaded rod, which can ensure the precise positioning of the blade during installation. The pin block is inserted into the rectangular hole, which can prevent the blade from rotating or displacing during use, thus maintaining the stability and accuracy during the cutting process.

[0022] Further, when the blade is a hob, the blade is a round hole, and the middle section of the threaded rod is a smooth shaft.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The round hole design of the hob allows the blade to cut the material efficiently. The smooth shaft part provides stable rotational support for the hob, enabling the hob to complete the cutting task more evenly and quickly, and is suitable for cutting larger areas or thicker materials.

[0025] Further, a rib plate is welded on the fixing plate, and the fixing plate, the rib plate and the handle are welded into a whole.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] As a strengthening member, the rib plate is fixed on the fixing plate by welding, which can significantly improve the rigidity and load-bearing capacity of the fixing plate. This design makes the whole structure more solid, can withstand greater cutting force and impact force, thereby extending the service life of the equipment. And when the user applies the cutting force through the handle, the force can be effectively transmitted to the blade on the fixing plate through the welded frame structure. This optimized force transmission path reduces the loss and dispersion of force, making the cutting process more efficient and powerful.

[0028] The utility model provides a building decoration cutting device. It has the following beneficial effects:

[0029] The device advances along the edge of the plate through the rollers, ensuring the stability during the cutting process, reducing the deviation and error, and improving the cutting precision. At the same time, the rollers are made of rubber material, increasing the friction with the plate, further ensuring the accuracy of the cutting path. And the rollers on both sides are connected by the main shaft, ensuring the synchronous rotation speed of the rollers. This synchronous design avoids the deviation of the device caused by inconsistent roller rotation speeds during the cutting process, thus maintaining the accuracy of the cutting path.

[0030] The design fully considers the convenience of the user. For example, the angle design (fifteen degrees) between the handle and the horizontal plane makes the wrist not easily fatigued during long-term use. The fixing plate, the rib plate and the handle are welded into a whole, enabling the force to be easily applied through the handle during cutting and transmitted to the blade, improving the operation comfort and efficiency.

[0031] The blade can be selected as a cutting knife or a hob according to needs, and the blade replacement is simple and fast. For the cutting knife, its fixing holes are designed as rectangles, which match the pin blocks on the threaded rod, ensuring the stable installation of the blade; for the hob, the middle section of the threaded rod is a smooth shaft, which is convenient for adapting the installation of the round-hole blade. This design increases the versatility and flexibility of the equipment.

[0043] Please refer to Figures 1 to 5 as shown in the embodiments provided by the present utility model:

[0044] Embodiment 1

[0045] A building decoration cutting device includes a bracket 1, a main shaft 3, a bearing 4, and a fixing plate 12. Bearings 4 are installed at both ends of the bracket 1, and the main shaft 3 is inserted into the bearings 4. The main shaft 3 is welded and fixed to the bearings 4. A keyway 2 is provided on the main shaft 3. A spline sleeve 7 is installed on the main shaft 3 between the bearings 4 by being limited by the keyway 2. Through holes are provided on the spline sleeve 7, and bolts are installed in the through holes. The spline sleeve 7 is locked and fixed to the main shaft 3 by the bolts. In some cases, it may be necessary to adjust the relative position between the spline sleeve 7 and the main shaft 3 according to the actual working conditions. By using bolt connection, it can be easily achieved by loosening the bolts, and this adjustment can be relatively easily realized, improving the maintainability and flexibility of the device to meet different usage requirements. A bushing 5 is sleeved on the outside of the spline sleeve 7, and rollers 6 are installed on the outside of the bushing 5. The two rollers 6 on both sides are connected as a whole through the main shaft 3, so that the two rollers 6 on both sides maintain the same rotation speed, thereby preventing the device from shifting during cutting. When in use, by making the rollers 6 clamp on both sides of the plate, the device advances along the edge of the plate through the rollers 6, further ensuring the accuracy of cutting. The rollers 6 are rubber rings, and grooves are provided on the bushing 5. The rollers 6 are installed in the grooves of the bushing 5 in a limited way. The rubber rollers 6 provide a relatively high friction force, which helps to improve the stability of the device on the plate. The elasticity and grip of the rubber enable the rollers 6 to better contact the surface of the plate, preventing sliding or shifting, thereby improving the cutting precision. The bushing 5 and the spline sleeve 7 are an integral part. A handle 14 is welded to the top of the bracket 1, and the angle between the handle 14 and the horizontal plane is 15 degrees. A fixing plate 12 is welded to one end of the bracket 1 close to the handle 14. A rib plate 13 is welded to the fixing plate 12. The fixing plate 12, the rib plate 13, and the handle 14 are welded into an integral part. When cutting, it is convenient for the user to press down the handle 14, and the force is transmitted to the blade 10 on the fixing plate through the handle 14 and the rib plate 13. As a strengthening member, the rib plate 13 is welded and fixed to the fixing plate 12, which can significantly improve the rigidity and load-bearing capacity of the fixing plate 12. This design makes the whole structure more solid, capable of withstanding greater cutting force and impact force, thereby extending the service life of the device. And when the user applies a cutting force through the handle 14, the force can be effectively transmitted to the blade 10 on the fixing plate 12 through the welded frame structure. This optimized force transmission path reduces the loss and dispersion of force, making the cutting process more efficient and powerful. A fixing frame 11 is welded to the lower surface of the fixing plate 12. A threaded rod 8 is clamped to the lower surface of the fixing plate 12 through the fixing frame 11. A blade 10 is installed on the threaded rod 8. Threads are provided at both ends of the threaded rod 8. The threaded rod 8 is installed with nuts 9 through the threads. The threaded rod 8 is locked to the fixing frame 11 by the nuts 9. By locking the threaded rod 8 to the fixing frame 11 with the nuts 9, it can be ensured that the blade 10 is firmly installed on the device, preventing the blade 10 from loosening or displacing during use. This stable fixing method ensures the precision and safety during the cutting process.

[0046] Example 2

[0047] As Figures 1 to 4 shown, a building decoration cutting device proposed by the present utility model, compared with Example 1, this embodiment further includes: The blade 10 is a cutting knife or a hob. Supporting two types of blades 10 (cutting knife and hob) enables the device to be used in different cutting tasks without the need to replace tools or equipment. This versatility makes the device more general and able to adapt to various cutting requirements, thereby improving the comprehensive utilization rate of the device. A cutting knife is usually used for fine cutting tasks, such as cutting thin plates or making precise line divisions. A hob is suitable for cutting larger areas, such as cutting thick plates or large pieces of material. The hob can provide stable cutting force and is suitable for more rugged cutting tasks, such as dividing large-area plates. When the blade 10 is a cutting knife, the fixing hole 15 of the blade 10 is rectangular, and a pin block 16 adapted to the size of the fixing hole 15 is provided in the middle section of the threaded rod 8. The rectangular fixing hole 15 cooperates with the pin block 16 on the threaded rod 8, which can ensure the precise positioning of the blade 10 during installation. The pin block 16 is inserted into the rectangular hole, which can prevent the blade 10 from rotating or displacing during use, thus maintaining the stability and accuracy during the cutting process. When the blade 10 is a hob, the blade 10 is a round hole, and the middle section of the threaded rod 8 is a smooth shaft. The round hole design of the hob allows the blade 10 to perform efficient cutting on the material. The smooth shaft part provides stable rotational support for the hob, enabling the hob to complete the cutting task more evenly and quickly, and is suitable for cutting larger areas or thicker materials.

[0048] Working principle:

[0049] When the device is in use, the rollers 6 are clamped on both sides of the plate. These rollers 6 are connected to the main shaft 3 through the bushings 5 to ensure the synchronous rotation of the rollers 6. The rubber ring of the rollers 6 has good friction, which can stably guide the device to move along the edge of the plate, avoiding the sliding and deviation of the device, and ensuring the accuracy of the cutting path.

[0050] The user applies a downward pressure through the handle 14. The handle 14 is connected to the bracket 1, the fixing plate 12 and the rib plate 13 to form an integral structure. This design allows the user's force to be transmitted to the fixing plate 12 through the handle 14 and further transferred to the cutting position of the blade 10 through the rib plate 13. The angle between the handle 14 and the horizontal plane makes the user's posture natural and comfortable during operation, effectively transmitting the applied force to the blade 10, thereby improving the cutting efficiency and accuracy.

[0051] The blade 10 is fixed on the fixing frame 11 by the threaded rod 8 and the nut 9. According to the different types of the blade 10 (cutting knife or hob), the shape of the fixing hole 15 of the blade 10 (rectangular or round hole) matches the design of the threaded rod 8 (with pin block 16 or smooth shaft) to ensure the stable installation of the blade 10. When the user presses down the handle 14, the blade 10 on the fixing plate 12 contacts the plate and cuts it. The movement of the blade 10 is driven by the main shaft 3 and guided by the rollers 6 to ensure that the cutting is carried out precisely along the edge of the plate.

[0052] The spline sleeve 7 and the bushing 5 on the main shaft 3 are designed such that the rollers 6 on both sides maintain the same rotational speed, avoiding the cutting line deviation caused by inconsistent rotational speeds during the cutting process. With this design, the device can maintain a stable cutting trajectory.

[0053] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
