Description

Technical Field

[0001] The present invention belongs to the technical field of plastic-steel profile cutting, and specifically relates to a cutting device for the production and processing of plastic-steel profiles. Background Art

[0002] Plastic-steel profiles are new building materials made from polyvinyl chloride (PVC) as the main raw material, added with a certain proportion of stabilizers, colorants, fillers, etc., through an extrusion molding process. Due to their characteristics such as light weight, corrosion resistance, excellent heat insulation and sound insulation performance, and low cost, they are widely used in fields such as building doors and windows, guardrails, and decorative lines, effectively improving the energy efficiency and aesthetics of buildings. With the rapid development of the construction industry and the decoration industry, the demand for plastic-steel profiles is increasing day by day, and their processing accuracy and production efficiency have also become the focus of the industry's attention.

[0003] In the production and processing of plastic-steel profiles, cutting is an indispensable and important link. Different building projects and decoration requirements have different dimensional specifications for plastic-steel profiles. Through precise cutting, plastic-steel profiles can be cut into lengths and shapes that meet the design standards to meet diverse application scenarios and ensure their tight fit during subsequent installation to achieve the best use effect. Therefore, the quality of the cutting process directly affects the finished product quality and production efficiency of plastic-steel profiles.

[0004] However, the existing cutting devices for plastic-steel profile production and processing have many drawbacks. On the one hand, due to the static electricity generated during the cutting process and the complex internal structure of the profiles, a large amount of debris will be adsorbed inside the plastic-steel profiles, and traditional cutting devices lack an effective cleaning mechanism and are difficult to remove this internal debris, which not only affects the appearance quality of the profiles but may also cause problems such as blockage and wear during subsequent use, reducing the service life and performance of the products. On the other hand, when the existing devices cut, they usually rely on manual placement and clamping operations according to the length that needs to be retained for the profiles. Affected by the subjective factors of the operators and their operating proficiency, it is extremely easy to cause human errors in the retained length of the profiles, making it difficult to meet the high-precision production requirements, and at the same time increasing the labor cost and time cost during the production process, restricting the improvement of production efficiency. Based on the above problems, it is urgent to develop a new cutting device for plastic-steel profile production and processing to overcome the deficiencies of the existing technology.

[0005] Therefore, it is necessary to provide a new cutting device for plastic-steel profile production and processing to solve the above technical problems. Summary of the Invention

[0015] The beneficial effects of the present invention compared with the prior art are as follows: 1. Precise positioning and efficient cutting: During the process of adjusting the position of the cutting saw blade and the protective cover, the lifting component will link with the pushing component to accurately push the plastic-steel profile to the predetermined position to avoid human errors. The lifting component drives the protective cover to move. The rising process of the protective cover is driven by the friction plate and the friction wheel to drive the pushing plate to push the plastic-steel profile to the predetermined position. Compared with manual placement, human errors are eliminated, the accuracy of the retained length of the profile is ensured, and the accuracy of the cutting size is greatly improved. At the same time, the lifting component can flexibly adjust the position of the cutting saw blade and the protective cover, and cooperate with the clamping block in the driving component to firmly clamp the plastic-steel profile, so that the cutting saw blade can cut the plastic-steel profile quickly and stably, effectively improving the cutting efficiency and cutting quality.

[0016] 2. All-round debris protection and cleaning: The inner wall of the protective cover adopts a bevel design. During the cutting process, the debris hits the bevel due to centrifugal force and rebounds downward, effectively preventing the debris from splashing toward the plastic-steel profile. This not only ensures the safety of the operator, but also reduces pollution to the working environment. After the cutting is completed, the drive motor in the drive assembly drives the clamp and the plastic-steel profile to rotate and vibrate. The centrifugal force and vibration can be used to completely remove the debris adsorbed inside the plastic-steel profile, solving the problem that the existing device cannot clean up the internal debris, ensuring the cleanliness of the profile, improving product quality, and reducing the risk of product damage caused by residual debris.

[0017] 3. High degree of automation and cost control: The various components of the device work together to achieve full-process automation from profile positioning, cutting to cleaning. The lifting components, pushing components, drive components, etc. are all driven by motors, which reduces manual intervention and reduces labor costs and time costs. At the same time, automated operation improves production stability and consistency, reduces the scrap rate caused by improper human operation, further reduces production costs, and improves production efficiency.

[0018] 4. Structural optimization and strong practicality: The workbench is equipped with linear slides and storage grooves, in which the push plate can be stored when not in use to avoid interference with the cutting operation and optimize the spatial layout of the device; the bevel design on the top of the clamp block, the anti-slip pad and the sliding connection with the movable plate enhance the clamping effect and applicability of the plastic-steel profiles; the friction plate groove design, the spline connection between the drive shaft and the movable shaft and other details are optimized to ensure the stability and reliability of the transmission between the components, making the device structure more reasonable and more practical, which is convenient for promotion and application in actual production.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail in combination with embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.

[0022] See Figures 1 to 14 , this embodiment provides a cutting device for the production and processing of plastic-steel profiles, including a workbench 1. A box body 2 is fixedly connected to the bottom of the workbench 1. A cutting saw blade 3 is installed inside the box body 2. A cutting motor 4 for driving the rotation of the cutting saw blade 3 is installed on one side of the cutting saw blade 3. The output end of the cutting motor 4 is fixedly connected to the cutting saw blade 3. Clamping blocks 5 for clamping the plastic-steel profile 45 are symmetrically installed in the middle of the top end of the workbench 1. Support columns 6 are fixedly connected to the four corners of the top of the workbench 1. A top plate 7 is fixedly connected to the tops of the four support columns 6. A protective cover 8 for blocking the splashing of cutting waste is slidably connected above the workbench 1 through the support columns 6. A lifting assembly for driving the lifting of the cutting saw blade 3 and the protective cover 8 is installed at one end of the box body 2 close to the cutting saw blade 3. A pushing assembly for determining the remaining length of the plastic-steel profile 45 is installed at one end of the workbench 1 away from the cutting saw blade 3. A driving assembly for driving the clamping blocks 5 to clamp the plastic-steel profile 45 and rotate and vibrate is installed in the middle of the top end of the box body 2. A plastic-steel profile 45 is placed between the two clamping blocks 5.

[0023] Place the plastic-steel profile 45 between the clamping blocks 5, with one end of the plastic-steel profile 45 close to the material-pushing component. Drive the cutting saw blade 3 and the protective cover 8 to rise through the lifting component, adjust the positions of the cutting saw blade 3 and the protective cover 8. During the movement, the lifting component will drive the material-pushing component to work through the protective cover 8. The material-pushing component will push the plastic-steel profile 45 to a predetermined position, so that the plastic-steel profile 45 retains a predetermined length. Then, make the clamping blocks 5 approach each other to clamp the plastic-steel profile 45 through the driving component. Drive the cutting saw blade 3 to cut the plastic-steel profile 45 through the cutting motor 4. After the cutting is completed, the lifting component drives the cutting saw blade 3 and the protective cover 8 to descend, so that the bottom surface of the protective cover 8 contacts the top surface of the workbench 1. The protective cover 8 encloses the plastic-steel profile 45. The driving component is started, and the plastic-steel profile 45 is driven to rotate and vibrate up and down through the clamping blocks 5. Use centrifugal force and vibration to make the debris adsorbed inside the plastic-steel profile 45 break away from the plastic-steel profile 45, realizing the cleaning of the cut plastic-steel profile 45.

[0024] As Figure 2 、 Figure 3 shown, the lifting component includes a connecting plate 9, a lifting motor 10, a first threaded rod 11 and a guide rod 12. The bottom of the cutting motor 4 is fixedly connected with a connecting plate 9. One end of the box body 2 close to the cutting saw blade 3 is fixedly connected with a lifting motor 10. The output end of the lifting motor 10 is fixedly connected with a first threaded rod 11. The first threaded rod 11 is threadedly connected with the connecting plate 9. The top end of the first threaded rod 11 passes through the workbench 1 and is rotatably connected with the top plate 7. The first threaded rod 11 is threadedly connected with one end of the protective cover 8. One side of the inside of the box body 2 where the first threaded rod 11 is located is fixedly connected with a guide rod 12. The guide rod 12 is slidably connected with the connecting plate 9.

[0025] Start the lifting component, the lifting motor 10 is powered on and runs, and its output end drives the first threaded rod 11 to rotate. Since the first threaded rod 11 is threadedly connected with the connecting plate 9, and the guide rod 12 plays a role of sliding limit for the connecting plate 9, the cutting motor 4, the cutting saw blade 3 fixed on the connecting plate 9, and the protective cover 8 threadedly connected with the first threaded rod 11 rise or fall synchronously.

[0026] As Figure 2 、 Figure 4 、 Figure 5 、 Figure 6As shown in the figure, the pusher component includes a pusher plate 13, a second threaded rod 14, a friction wheel 15 and a friction plate 16. A pusher plate 13 is installed at one end of the workbench 1 away from the cutting saw blade 3. The pusher plate 13 pushes the plastic-steel profile 45 to move a specified distance. The second threaded rod 14 is rotatably connected inside the workbench 1. The second threaded rod 14 is threadedly connected to the pusher plate 13. One end of the second threaded rod 14 is fixedly connected to the friction wheel 15. One end of the protective cover 8 away from the first threaded rod 11 is fixedly connected to the friction plate 16. One side of the friction plate 16 is in rolling connection with the friction wheel 15. A linear chute 37 is opened at the top of the workbench 1. The pusher plate 13 extends out of the workbench 1 through the linear chute 37 and slides in the linear chute 37. A storage groove 38 for storing the pusher plate 13 is opened at the top of the workbench 1. One end of the storage groove 38 is communicated with one end of the linear chute 37. A groove 39 is opened at the bottom of the friction plate 16 near one side of the friction wheel 15. The friction plate 16 does not contact the friction wheel 15 at the groove 39. A limiting square column 40 is fixedly connected inside the workbench 1. The top surface of the limiting square column 40 contacts the bottom surface of the pusher plate 13.

[0027] During the upward movement of the protective cover 8, the friction plate 16 fixed at one end of the protective cover 8 contacts the friction wheel 15 at one end of the second threaded rod 14 and generates friction force. Based on the principle of friction drive, the friction plate 16 drives the friction wheel 15 to rotate clockwise. The friction wheel 15 is fixedly connected to the second threaded rod 14, and the pusher plate 13 is threadedly connected to the second threaded rod 14 that rotates inside the workbench 1. At this time, the top surface of the limiting square column 40 contacts the bottom surface of the pusher plate 13, and the limiting square column 40 restricts the pusher plate 13 from rotating clockwise. During the rotation of the second threaded rod 14, it will drive the pusher plate 13 to slide in the linear chute 37 at the top of the workbench 1. As the protective cover 8 rises, when the groove 39 opened on one side of the friction plate 16 is flush with the middle of the friction wheel 15, the contact between the friction plate 16 and the friction wheel 15 is released. At this time, the pusher plate 13 just pushes the plastic-steel profile 45 to the predetermined position, and at this time, the cutting saw blade 3 has not contacted the plastic-steel profile 45.

[0028] As Figure 4 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12As shown in the figure, the driving assembly includes a rotating disk 17, a connecting rod 18, a movable disk 19, a fixed disk 20, a driving box 21, a clamping motor 22, a worm 23, a rotating shaft 24, a worm gear 25, a first driving gear 26, a cylindrical rack 27, a first driven gear 28, a bidirectional threaded rod 29 and a limiting rod 30; the middle of the top end of the workbench 1 is rotatably connected with a rotating disk 17, and the rotating disk 17 can only rotate horizontally. Connecting rods 18 are symmetrically installed at both ends of the rotating disk 17. Above the rotating disk 17, a movable disk 19 is slidably connected through the connecting rod 18. The bottom of the rotating disk 17 is rotatably connected with a fixed disk 20. The fixed disk 20 is fixedly connected with the box body 2. The bottom of the fixed disk 20 is fixedly connected with a driving box 21. The bottom of the driving box 21 is fixedly connected with a clamping motor 22 for controlling the clamping blocks 5 to move towards or away from each other. The output end of the clamping motor 22 is fixedly connected with a worm 23. Inside the driving box 21, a rotating shaft 24 is rotatably connected. On the outer wall of one end of the rotating shaft 24, a worm gear 25 is fixedly connected. On the outer wall of the other end of the rotating shaft 24, a first driving gear 26 is fixedly connected. The worm gear 25 is meshed with the worm 23. A cylindrical rack 27 is slidably connected in the middle of the driving box 21. The cylindrical rack 27 is meshed with the first driving gear 26. Inside the rotating disk 17, first driven gears 28 are symmetrically and rotatably connected. The first driven gears 28 are both meshed with the cylindrical rack 27. The inner walls of the first driven gears 28 are both fixedly connected with bidirectional threaded rods 29. The two ends of the bidirectional threaded rod 29 are respectively threadedly connected with limiting rods 30. The ends of the limiting rods 30 are slidably connected with the corresponding clamping blocks 5. On one side of the two clamping blocks 5 facing each other, anti-slip sheets 44 are fixedly connected. The ends of the clamping blocks 5 facing each other at the top are designed with bevels.

[0029] After the plastic-steel profile 45 is accurately pushed to the predetermined position, the clamping motor 22 in the driving assembly is started. The worm 23 at the output end of the clamping motor 22 rotates accordingly. The worm 23 drives the worm gear 25 meshed with it to rotate. The worm gear 25 drives the rotating shaft 24 to rotate, and then the first driving gear 26 fixed to the other end of the rotating shaft 24 rotates. The first driving gear 26 is meshed with the cylindrical rack 27, converting the rotational motion into the linear motion of the cylindrical rack 27, making the cylindrical rack 27 approach the clamping motor 22. Since the cylindrical rack 27 is meshed with the first driven gears 28 symmetrically arranged inside the rotating disk 17, and the first driven gears 28 are fixedly connected with the bidirectional threaded rods 29, the cylindrical rack 27 will drive the first driven gears 28 to rotate, and then drive the bidirectional threaded rods 29 to rotate synchronously through the first driven gears 28. As the bidirectional threaded rod 29 rotates, the limiting rods 30 threadedly connected to its two ends move along the axial direction of the bidirectional threaded rod 29, driving the clamping blocks 5 to approach each other, and firmly clamping the plastic-steel profile 45 through the anti-slip sheets 44 on one side of the clamping blocks 5 facing each other.

[0030] When the plastic-steel profile 45 is stably clamped, with the continuous driving of the lifting motor 10, the cutting saw blade 3 extends out from the bottom of the workbench 1. The cutting motor 4 is powered on and operates. Its output end directly drives the cutting saw blade 3 to rotate at high speed. At this time, the lifting motor 10 continues to drive, and controls the cutting saw blade 3 and the protective cover 8 to move upward through the first threaded rod 11, so that the cutting saw blade 3 cuts into the plastic-steel profile 45 for cutting operations. Since the inner wall of the protective cover 8 is designed with an inclined surface, during the cutting process, the generated debris will bounce downward after hitting the inclined inner wall of the protective cover 8 under the action of centrifugal force, avoiding the splashing of debris towards the plastic-steel profile 45, and effectively ensuring the safety of the operator and the cleanliness of the working environment.

[0031] As Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 shown, the driving assembly further includes a driving motor 31, a second driving gear 32, a driving shaft 33, a movable shaft 34, a reciprocating chute 35 and a slider 36. The bottom of the driving box 21 on one side of the clamping motor 22 is fixedly connected with a driving motor 31. The output end of the driving motor 31 is fixedly connected with a second driving gear 32. The inside of the driving box 21 is rotatably connected with a second driven gear 46. The second driving gear 32 is meshed with the second driven gear 46. The side of the second driven gear 46 away from the driving motor 31 is fixedly connected with a driving shaft 33. The top of the driving shaft 33 is slidably connected with a movable shaft 34. The top of the movable shaft 34 is fixedly connected with the movable disk 19. The outer wall of the movable shaft 34 is slidably connected with the inner wall of the cylindrical rack 27. The inside of the driving box 21 is fixedly connected with a reciprocating column 47. A reciprocating chute 35 is opened inside the reciprocating column 47. The outer wall of one end of the movable shaft 34 close to the driving motor 31 is fixedly connected with a slider 36. The slider 36 slides in the reciprocating chute 35. The outer wall of one end of the driving shaft 33 is provided with an internal spline 41. The inner wall of one end of the movable shaft 34 is provided with an external spline 42. The external spline 42 slides inside the internal spline 41. Through the design of the internal spline 41 and the external spline 42, the driving shaft 33 can drive the movable shaft 34 to perform rotational motion, and at the same time, the movable shaft 34 can also slide along the axial direction of the driving shaft 33.

[0032] After the cutting task is completed, the cutting motor 4 is turned off, and the lifting motor 10 rotates in the reverse direction and drives the cutting saw blade 3 and the protective cover 8 to descend through the first threaded rod 11 until the bottom surface of the protective cover 8 is in close contact with the top surface of the workbench 1, forming an enclosed space for the plastic-steel profile 45. During the descent of the protective cover 8, the friction plate 16 will descend synchronously. When the top of the groove 39 is level with the middle of the friction wheel 15, as the friction plate 16 descends, the friction plate 16 is reconnected to the friction wheel 15 in a rolling manner, and the friction plate 16 drives the friction wheel 15 to rotate counterclockwise. At this time, the pusher plate 13 is located inside the linear chute 37, and the side wall of the linear chute 37 restricts the pusher plate 13 from rotating counterclockwise along with the second threaded rod 14. Therefore, the friction wheel 15 drives the pusher plate 13 to move to the connection between the linear chute 37 and the storage groove 38 through the second threaded rod 14. Before this, the pusher plate 13 is vertical, and the limiting square column 40 is located below the pusher plate 13, and the limiting square column 40 does not restrict the pusher plate 13. As the friction wheel 15 further rotates counterclockwise, at the storage groove 38, because the linear chute 37 can no longer restrict the rotation of the pusher plate 13, the friction wheel 15 drives the pusher plate 13 to rotate counterclockwise through the second threaded rod 14, causing the pusher plate 13 to rotate into the storage groove 38. After the pusher plate 13 enters the storage groove 38, the limiting square column 40 is located on one side of the pusher plate 13, and the limiting square column 40 limits the pusher plate 13.

[0033] Start the drive motor 31. The second driving gear 32 at the output end thereof meshes with the second driven gear 46, thereby transmitting power to the drive shaft 33. Since internal splines 41 are provided on the outer wall of one end of the drive shaft 33 and external splines 42 are provided on the inner wall of one end of the movable shaft 34, the drive shaft 33 can drive the movable shaft 34 to rotate synchronously when rotating, and at the same time, the movable shaft 34 can also slide along the axial direction of the drive shaft 33. The top of the movable shaft 34 is fixedly connected to the movable disk 19, and its outer wall is slidably connected to the inner wall of the cylindrical rack 27. Moreover, the slider 36 at one end of the movable shaft 34 slides in the reciprocating chute 35 of the reciprocating column 47 inside the drive box 21. Under this structural design, while the drive motor 31 drives the movable shaft 34 to rotate, the sliding of the slider 36 in the reciprocating chute 35 causes the movable shaft 34 to perform reciprocating up and down movements, and then drives the clamping block 5 and the clamped plastic-steel profile 45 to rotate and vibrate up and down through the movable disk 19. By means of the centrifugal force and vibration effects, the debris adsorbed inside the plastic-steel profile 45 can be effectively separated from the plastic-steel profile 45, realizing the cleaning treatment of the cut plastic-steel profile 45. The inner wall of the protective cover 8 is designed as an inclined surface. The clamping block 5 is slidably connected to the movable disk 19 through the cross bar 43. The debris impacts on the inclined inner wall of the protective cover 8 under the action of the centrifugal force and rebounds downward, avoiding the debris rebounding towards the plastic-steel profile 45 direction and ensuring the stability of the cleaning.

[0034] After the cleaning is completed, turn off the driving motor 31, and then start the lifting motor 10. The lifting motor 10 drives the cutting saw blade 3 and the protective cover 8 to reset. The protective cover 8 drives the second threaded rod 14 to rotate clockwise through the friction plate 16 and the friction wheel 15. During the rotation of the second threaded rod 14, the pushing plate 13 in the storage groove 38 will be driven to rotate clockwise into the linear sliding groove 37, and the bottom surface of the pushing plate 13 will contact the limiting square column 40. The limiting square column 40 prevents the pushing plate 13 from continuing to rotate clockwise. Start the clamping motor 22, and make the clamping motor 22 rotate in the reverse direction to drive the clamping block 5 to reset, and take out the plastic-steel profile 45 to complete the entire work process.

It cannot be determined that the specific embodiments of the present invention are limited to this. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the premise of the present invention, several simple deductions or replacements can be made, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
