Description

Technical Field

[0001] The utility model relates to the technical field of air duct machine cutting equipment, in particular to a follow-up saw mechanism for cutting a full-automatic spiral air duct machine. Background Technique

[0002] The full-automatic spiral air duct is usually made of metal strip material by an air duct machine. It is through a plurality of groups of traction and folding press wheel groups arranged on the spiral air duct machine. On the one hand, the two sides of the metal strip material are bent into occluding edges, and on the other hand, the metal strip material is pulled forward. And through a guiding device arranged at the rear of the traction press wheel group and at a certain angle with the advancing direction of the metal strip material, the advancing direction is changed, so that the advancing metal strip material enters the inner wall of the fixed strip mold and curls along a set angle in a spiral line. At the same time, the occluding edges on both sides of the metal strip material pass through the active lower press wheel and the passive upper press wheel in the rolling device at the front end of the fixed strip mold to form an embedded bottom seam edge, thereby manufacturing a spiral air duct.

[0003] However, the existing full-automatic spiral air duct machines are not convenient for cutting when discharging the air duct. It is necessary to stop the machine to cut the spiral air duct, with low cutting efficiency and reduced overall work efficiency. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A follow-up saw mechanism for cutting a full-automatic spiral air duct machine, including: two tracks and a moving plate. The moving plate is located at the lower ends of the two tracks, and rollers are installed on the four sides of the upper end of the moving plate. The outer wall of the roller is in rolling connection with the inner wall of the track;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to clearly and completely describe the purpose and technical solutions of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a follow-up saw mechanism for cutting a full-automatic spiral air duct machine, including: two tracks 1 and a moving plate 2. The moving plate 2 is located at the lower ends of the two tracks 1, and rollers 11 are installed on the four sides of the upper end of the moving plate 2. Cylinders 9 are fixedly installed on the four sides of the upper end of the moving plate 2. A moving block 10 is fixedly installed at the upper end of the cylinder 9. The four ends of the moving block 10 are rotatably connected to the rollers 11. The outer wall of the roller 11 is in rolling connection with the inner wall of the track 1. By allowing the roller 11 to roll in the track 1, the moving plate 2 is driven to move between the two tracks 1.

[0024] A motor 6 is installed at the lower end of the moving plate 2 through a lifting member. A cutting blade 7 is fixedly installed at the output end of the motor 6. When the motor 6 is started, the cutting blade 7 can be driven to rotate to cut the spiral air duct. The lifting member includes sliding holes 3 opened at the left and right ends of the moving plate 2. A guide rod 4 is slidably connected in the sliding holes 3. The lower end of the guide rod 4 passes through the sliding holes 3 and is fixedly installed with a mounting plate 5. The motor 6 is fixedly installed at the lower end of the mounting plate 5. When the moving plate 2 moves in the track 1, the motor 6 and the cutting blade 7 are synchronously moved. An electric push rod 8 is fixedly installed between the mounting plate 5 and the moving plate 2. One end of the electric push rod 8 is fixed on the mounting plate 5, and the other end is fixed on the lower end of the moving plate 2. When the electric push rod 8 is started, the mounting plate 5 can be driven to move the motor 6 and the cutting blade 7, realizing the lifting of the cutting blade 7, which is convenient for cutting the spiral air duct.

[0025] One end of the track 1 is fixedly installed with a fixing sleeve 12 through bolts. The fixing sleeve 12 is sleeved on the outer end of the track 1. Bolt holes are provided on the side walls of both the fixing sleeve 12 and the track 1. After the bolt passes through the bolt hole, it is threadedly connected with a nut. An ear block 13 is fixedly installed at the lower end of the fixing sleeve 12. A round hole 14 is provided on the side wall of the ear block 13. A moving column 15 is slidably connected in the round hole 14. One end of the moving column 15 slidably passes through the round hole 14 and is fixedly connected to a baffle 16. A spring 17 is sleeved on the outer wall of the moving column 15. One end of the spring 17 is fixed on the baffle 16, and the other end is fixed on the ear block 13. The baffle 16 moves towards one side of the ear block 13 by compressing the spring 17. At the same time, the moving column 15 slides in the round hole 14. The baffle 16 and the spring 17 play a role in buffering the moving plate 2. The other end of the track 1 is fixedly installed with a fixing plate 18 through bolts.

[0026] The device is fixed to the upper end of the outlet of the full-automatic air duct machine through the fixing plate 18, so that the cutting piece 7 is located directly above the spiral air duct, facilitating the cutting of the spiral air duct.

[0027] During actual use, when the spiral air duct needs to be cut, the electric push rod 8 is started. The electric push rod 8 drives the motor 6 and the cutting piece 7 to move downward. The cutting piece 7 contacts the spiral air duct and cuts it. The air duct outlet of the spiral air duct will push the cutting piece 7 and the motor 6 to move. The motor 6 will drive the moving plate 2 to move. The moving plate 2 moves in the track 1 through the rollers 11. As a result, the cutting piece 7 on the motor 6 will also change with the speed of the air duct outlet of the spiral air duct. This enables the present utility model to synchronously cut the spiral air duct when the full-automatic spiral air duct machine discharges the air duct, eliminating the need to turn off the full-automatic spiral air duct machine to cut the spiral air duct, improving the cutting effect, thereby enhancing the work efficiency and having strong practicability.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
