Description

Technical Field

[0001] This utility model relates to the technical field of cotton harvester baling film production, specifically a cutting device for cotton harvester baling film production. Background Technology

[0002] The cotton harvester requires two types of film for baling cotton: one without adhesive and the other with single-sided adhesive. During production, one type of film is released first and conveyed forward, while the rollers behind it roll it up to a certain size (according to the specifications required by the cotton harvester). The equipment's pressure plate holds it down, and the cutter cuts the film. Then, the equipment conveys the other type of film. One end of the equipment is equipped with a hot melt adhesive device that applies a layer of hot melt adhesive to the cut surface. The purpose of applying the hot melt adhesive is to bond the two types of film together.

[0003] However, in the existing technology, after the cotton harvester baling film is produced, it needs to be wound onto a roller for easy transportation. After the baling film is wound onto the roller, it needs to be cut. The baling film is laid flat on the machine table, and a pressure plate driven to rotate on the machine table presses down on the baling film. A moving slide rail is set below the machine table, and a cutting blade is set at the top of a sliding frame driven to move within the moving slide rail. The cutting blade moves along the pre-reserved groove on the machine table to cut the cotton harvester baling film. During use, when not cutting, the cutting blade will be driven to move to one side of the machine table. At this time, there is a risk that the operator may accidentally touch the cutting blade and be cut. Improvement and optimization are needed.

[0004] Therefore, this utility model proposes a cutting device for producing cotton harvester baling film to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a cutting device for producing cotton picking machine baling film, comprising: a machine base 1 and a cutting blade 6; the machine base 1 is provided with a blade groove, and a pressure plate 2 is symmetrically rotatably arranged on the machine base 1, the pressure plate 2 being located on both sides of the blade groove; an electric push rod 3 is symmetrically rotatably arranged on the machine base 1, the output end of the electric push rod 3 being rotatably connected to the pressure plate 2; a movable slide rail 4 is connected to the bottom end of the machine base 1, a slide frame 5 is driven and connected inside the movable slide rail 4, and the cutting blade 6 is connected to the top end of the slide frame 5; a protective component is provided on the machine base 1.

[0021] The electric push rod 3 extends and retracts to control the rotation of the pressure plate 2 to lift or press down. During cutting, the pressure plate 2 rotates and presses down to press the cotton harvester baling film onto the table surface of the machine base 1. The drive carriage 5 moves within the moving slide rail 4, causing the cutting blade 6 to move along the blade groove on the machine base 1 to cut the cotton harvester baling film.

[0022] The U-shaped frame 7 in the protective assembly is symmetrically connected and installed on both sides of the machine base 1. The frame plate 8 is rotatably installed in the groove of the U-shaped frame 7. The side wall of the frame plate 8 is provided with mounting holes 9. The side wall of the U-shaped frame 7 is threaded with a knob screw 10, which is inserted into the mounting hole 9.

[0023] After rotating the frame plate 8 to cover and shield the U-shaped frame 7, rotate the knob screw 10 to insert it into the mounting hole 9 on the side wall of the frame plate 8 to fix the position of the frame plate 8. In the non-cutting state, the cutting blade 6 moves to the side of the machine 1 and is located in the groove of the U-shaped frame 7. The frame plate 8 cooperates with the U-shaped frame 7 to wrap the cutting blade 6, so as to prevent personnel from accidentally touching the cutting blade 6 and causing injury.

[0024] A T-shaped plate 11 is inserted into the end wall of the U-shaped frame 7, and a U-shaped plate 12 is connected to the bottom end of the T-shaped plate 11. The U-shaped plate 12 is movably disposed in the groove of the U-shaped frame 7, and the cutting blade 6 is movably disposed in the groove of the U-shaped plate 12.

[0025] The U-shaped plate 12 has trapezoidal slots 13 symmetrically opened on both sides of the side wall, and the L-shaped plate 14 is symmetrically arranged in the groove of the U-shaped plate 12. The L-shaped plate 14 has trapezoidal blocks 15 connected to its side wall. The trapezoidal blocks 15 are engaged with the trapezoidal slots 13, and the frame plate 8 is engaged with the L-shaped plate 14 and the trapezoidal blocks 15.

[0026] A scraper 16 is connected to the bottom wall of the L-shaped plate 14, and the scraper 16 contacts the cutting blade 6. A wiping cloth 17 is connected to the side wall of the L-shaped plate 14, and the wiping cloth 17 contacts the cutting blade 6.

[0027] The trapezoidal locking block 15 engages with the trapezoidal locking slot 13, and simultaneously cooperates with the frame plate 8 to limit and engage the L-shaped plate 14 and the trapezoidal locking block 15, so that the L-shaped plate 14 is installed in the groove of the U-shaped plate 12. The T-shaped plate 11 controls the U-shaped plate 12 and the L-shaped plate 14 to move downward. During the process, the scraper 16 moves downward along the cutting blade 6 to remove the cutting debris adhering to the cutting blade 6. At the same time, the surface of the wiping cloth 17 can be coated with lubricating oil to wipe and maintain the cutting blade 6.

[0028] The T-shaped plate 11 has a positioning groove 18 on its side wall, and a rotating plate 19 is rotatably mounted on the end wall of the U-shaped frame 7. The rotating plate 19 is engaged with the positioning groove 18. The rotating plate 19 has a buckle groove 20 on its side wall. A protrusion 21 is connected to the end wall of the U-shaped frame 7. An elastic buckle 22 is connected to the side wall of the protrusion 21. The rotating plate 19 is engaged with the protrusion 21, and the elastic buckle 22 is engaged with the buckle groove 20.

[0029] Rotate the rotating plate 19 into the positioning groove 18 on the side wall of the T-shaped plate 11 until the rotating plate 19 engages with the protrusion 21 and the elastic buckle 22 engages with the buckle groove 20 to fix the position of the T-shaped plate 11, so that the positions of the U-shaped plate 12 and the L-shaped plate 14 are fixed above the cutting blade 6 to avoid affecting the movement of the cutting blade 6.

[0030] Working principle: The electric push rod 3 pushes the pressure plate 2 to rotate and press down, pressing the cotton harvester baling film onto the table surface of the machine platform 1. The drive slide 5 moves within the moving slide rail 4, causing the cutting blade 6 to move along the blade groove on the machine platform 1 to cut the cotton harvester baling film. After that, the cutting blade 6 moves to the side of the machine platform 1 and is located in the groove of the U-shaped frame 7. The frame plate 8, together with the U-shaped frame 7, wraps around the cutting blade 6 to prevent personnel from accidentally touching the cutting blade 6 and causing injury. At the same time, the rotating plate 19 is unlocked and separated from the positioning groove 18. The T-shaped plate 11 moves downward, thereby controlling the U-shaped plate 12 and L-shaped plate 14 to move downward. During the process, the scraper 16 moves downward along the cutting blade 6 to remove the cutting debris adhering to the cutting blade 6. At the same time, the surface of the wiping cloth 17 can be coated with lubricating oil to wipe and maintain the cutting blade 6.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
