[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides a technical solution:
[0024] See Figure 1 set Figure 2As shown, a shearing device for processing environmentally friendly PVC doors and windows includes a cutting box 1. Vertical plates 2 are installed on both sides of the cutting box 1. A horizontal plate 11 is connected to the top of the two vertical plates 2. A cutting head body 8 is installed on the lower surface of the horizontal plate 11. The horizontal plate 11 is equipped with a dust removal mechanism, which includes two mounting plates 12 installed on the lower surface of the horizontal plate 11. A motor 13 is fixedly mounted on one of the mounting plates 12. The drive shaft of the motor 13 is driven by a reciprocating screw 14. The other end of the reciprocating screw 14 is connected to the other mounting plate 12. The mounting plate 12 is rotatably connected, and the reciprocating screw 14 is threadedly connected to a threaded block 15. The bottom end of the threaded block 15 is hinged to a movable rod 16, and the other end of the movable rod 16 is hinged to an installation tube 17. The middle section of the installation tube 17 is hinged to a swing rod 19. Several air nozzles 18 are installed on the lower surface of the installation tube 17. The end of the installation tube 17 away from the movable rod 16 is connected to an air blowing hose 7. The installation tube 17 extends to the top of the horizontal plate 11. An air pump 6 is installed on the upper surface of the horizontal plate 11, and the air pump 6 is connected to the air blowing hose 7.
[0025] In the specific implementation process, the cutting head body 8 performs cutting operations below the horizontal plate 11. During the cutting process, a large amount of dust and debris are generated. In order to reduce the impact of dust and debris on the working environment, the dust removal mechanism starts working, the motor 13 starts, and drives the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 drives the threaded block 15 to reciprocate. The bottom end of the threaded block 15 is hinged to the mounting tube 17 through the movable rod 16. Therefore, the mounting tube 17 also swings with the reciprocating motion of the threaded block 15. Several air nozzles are installed on the lower surface of the mounting tube 17. 18. The installation pipe 17 is connected to the air pump 6 through the air blowing hose 7. The airflow generated by the air pump 6 enters the installation pipe 17 through the air blowing hose 7 and is sprayed out from the air blowing nozzle 18, blowing away the dust and debris generated during the cutting process from the working area. Since the swing rod 19 is hinged above the middle section of the installation pipe 17, the installation pipe 17 will swing while reciprocating, thereby expanding the coverage of the air blowing nozzle 18 and improving the dust removal effect. The entire dust removal process is carried out continuously during the cutting operation to ensure a clean working environment and reduce the impact of dust on the health of operators.
[0026] See figure and Figure 4As shown, a dust collection tray 3 is provided on the inner bottom wall of the cutting box 1. A square groove matching the front of the dust collection tray 3 is provided on the front of the cutting box 1. The dust collection tray 3 is slidably connected to the cutting box 1 through the square groove. A frame 10 is installed on the inner side wall of the dust collection tray 3. A dust collection screen 9 is fixedly installed on the inner side wall of the frame 10. The dust collection tray 3 and the frame 10 are provided with a disassembly mechanism. The disassembly mechanism includes fixing pieces 5 fixedly installed at the four corners of the front and back of the dust collection tray 3. Both the dust collection tray 3 and the frame 10 are provided with mounting grooves matching the fixing pieces 5. An abutment block 24 is slidably connected in the mounting groove. A sliding column 25 is fixedly installed on the side of the abutment block 24 near the fixing piece 5. One end of the sliding column 25 passes through the fixing piece 5, and an mounting block 27 is installed at the end of the sliding column 25. A compression spring 26 is sleeved on the sliding column 25. The two ends of the compression spring 26 are fixedly connected to the opposite sides of the abutment block 24 and the fixing piece 5, respectively. In the specific implementation process, during the cutting process, the dust and debris generated by the cutting head body 8 are blown towards the inner bottom wall of the cutting box 1 by the air nozzle 18. The dust collection tray 3 is slidably connected to the cutting box 1 through a square groove, and the dust and debris are collected in the dust collection tray 3. A frame 10 is installed on the inner side wall of the dust collection tray 3, and a dust collection screen 9 is fixedly installed on the inner side wall of the frame 10. The dust and debris are filtered through the dust collection screen 9. Larger debris is intercepted on the dust collection screen 9, while smaller dust particles are collected in the dust collection tray 3. When the dust and debris in the dust collection tray 3 accumulate to a certain level, the dust collection tray 3 and the dust collection screen 9 need to be cleaned and disassembled. The design of the mechanism allows for easy disassembly and installation of the dust collection drawer 3 and the frame 10. When the operator pulls the mounting block 27, the abutment block 24 slides in the mounting groove and moves toward the fixing plate 5, compressing the compression spring 26. When the abutment block 24 is completely disengaged from the mounting groove of the frame 10, the dust collection drawer 3 and the frame 10 can slide out of the cutting box 1 for easy cleaning. After cleaning, the dust collection drawer 3 and the frame 10 are reinserted into the square groove of the cutting box 1. The abutment block 24 automatically resets under the action of the compression spring 26 and abuts against the mounting groove, ensuring that the dust collection drawer 3 and the frame 10 are securely installed.
[0027] See Figure 1 and Figure 2 As shown, a handle 4 is installed on the front of the dust collection drawer 3, and a groove is provided on the lower surface of the horizontal plate 11. The groove matches the cross-section of the threaded block 15. In the specific implementation, the handle 4 is installed on the front of the dust collection drawer 3. This design is mainly to facilitate the user's operation of pulling out and pushing in the dust collection drawer 3. The groove provided on the horizontal plate 11 can guide the movement trajectory of the threaded block 15 below the horizontal plate 11. When the motor 13 drives the reciprocating screw 14 to rotate, the threaded block 15 will reciprocate along the groove. The design of the groove ensures that the movement path of the threaded block 15 is stable and controllable. The groove may also have a certain depth to accommodate part of the structure of the threaded block 15, thereby further increasing the stability and accuracy of the movement.
[0028] SeeFigure 3 As shown, placement plates 20 are symmetrically installed on the inner walls of both sides of the cutting box 1. Each placement plate 20 has a fixing mechanism, including movable grooves at both ends of the upper surface of the placement plate 20. Guide posts 22 are installed within these grooves, and movable blocks matching the grooves are slidably connected to the guide posts 22. Clamping plates 21 are fixedly installed on the upper surfaces of the two movable blocks. Tension springs 23 are sleeved on the guide posts 22, with both ends of the tension springs 23 fixedly connected to the inner walls of the grooves and the movable blocks, respectively. In practical implementation, when it is necessary to fix door and window materials, the user simply places the materials on the two placement plates 20. The materials will push the clamping plates 21 to slide to both sides. Due to the presence of the tension springs 23, the clamping plates 21 can tightly adhere to both sides of the materials under the action of elastic force, thus fixing the materials.
[0029] Working principle:
[0030] Step 1: The cutting head body 8 performs cutting operations below the horizontal plate 11. During the cutting process, a large amount of dust and debris are generated. To reduce the impact of dust and debris on the working environment, the dust removal mechanism starts working. The motor 13 starts, driving the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 drives the threaded block 15 to reciprocate. The bottom end of the threaded block 15 is hinged to the mounting tube 17 through the movable rod 16. Therefore, the mounting tube 17 also swings with the reciprocating motion of the threaded block 15. Several air nozzles 18 are installed on the lower surface of the mounting tube 17. The mounting tube 17 is connected to the air pump 6 through the air blowing hose 7. The airflow generated by the air pump 6 enters the mounting tube 17 through the air blowing hose 7 and is sprayed out from the air nozzles 18, blowing the dust and debris generated during the cutting process away from the working area. Since the swing rod 19 is hinged above the middle section of the mounting tube 17, the mounting tube 17 swings while reciprocating, thereby expanding the coverage of the air nozzles 18 and improving the dust removal effect.
[0031] Step Two: During the cutting process, dust and debris are blown by the air nozzle 18 towards the inner bottom wall of the cutting box 1. The dust collection tray 3 is slidably connected to the cutting box 1 via a square groove, and the dust and debris are collected in the dust collection tray 3. A frame 10 is installed on the inner side wall of the dust collection tray 3, and a dust collection screen 9 is fixedly installed on the inner side wall of the frame 10. The dust and debris are filtered through the dust collection screen 9. Larger debris is intercepted on the dust collection screen 9, while smaller dust particles are collected in the dust collection tray 3. When the dust and debris in the dust collection tray 3 accumulate to a certain level, the dust collection tray 3 and the dust collection screen 9 need to be cleaned. The design of the easy-to-disassemble mechanism makes it possible to... The dust collection drawer 3 and the frame 10 can be easily disassembled and installed. When the operator pulls the mounting block 27, the abutment block 24 slides in the mounting groove and moves toward the fixing plate 5. The compression spring 26 is compressed. When the abutment block 24 is completely disengaged from the mounting groove of the frame 10, the dust collection drawer 3 and the frame 10 can slide out of the cutting box 1 for easy cleaning. After cleaning, the dust collection drawer 3 and the frame 10 are reinserted into the square groove of the cutting box 1. The abutment block 24 automatically resets under the action of the compression spring 26 and abuts against the mounting groove to ensure that the dust collection drawer 3 and the frame 10 are securely installed.
[0032] Step 3: A handle 4 is installed on the front of the dust collection drawer 3, which makes it easy for users to pull out and push in the dust collection drawer 3. The slide groove opened in the horizontal plate 11 can guide the movement trajectory of the threaded block 15 under the horizontal plate 11, ensuring that the movement path of the threaded block 15 is stable and controllable. The inner walls on both sides of the cutting box 1 are symmetrically equipped with placement plates 20. The placement plates 20 are equipped with fixing mechanisms. When it is necessary to fix door and window materials, the user only needs to place the materials on the two placement plates 20. The materials will push the clamping plates 21 to slide to both sides. Due to the presence of the tension spring 23, under the action of elastic force, the clamping plates 21 can fit tightly against both sides of the materials to fix the materials.
