Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a multi-position synchronous die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting, creasing, hot stamping, bonding, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc.

[0003] In the existing technology, the position of the die-cutting blade is usually fixed, which is inconvenient to adjust. Each time the position of the cutting blade is adjusted, the bolt needs to be tightened. After multiple adjustments, the bolt will be tightened multiple times, which will damage the threads between the bolt and the bolt hole, making the bolt unstable and requiring a lot of work. Utility Model Content

[0004] The purpose of this invention is to provide a multi-position synchronous die-cutting machine to solve the problem mentioned in the background art that the position of the die-cutting blade is usually fixed and inconvenient to adjust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-position synchronous die-cutting machine, comprising: a table body, a support frame fixedly installed on the upper end of the table body, a movable frame installed in the inner end of the support frame that can be raised and lowered, a rotating rod rotatably connected to the inner end of the movable frame, threaded grooves symmetrically opened on the left and right ends of the rotating rod, and threaded sleeves symmetrically threadedly connected to the left and right ends of the rotating rod through the threaded grooves.

[0006] Each threaded sleeve has a drive frame fixedly installed on one side, and a telescopic frame is installed between the two drive frames. Several connecting rods are evenly and detachably installed at the lower end of the telescopic frame, and a die-cutting blade is installed at the lower end of each connecting rod through a blade holder.

[0007] Furthermore, both the support frame and the movable frame are U-shaped. Fixed cylinders are fixedly installed on the upper left and right sides of the platform. The fixed cylinders are located inside the support frame, and the lower left and right sides of the movable frame are slidably inserted into the fixed cylinders. An electric push rod is fixedly installed on the upper end of the support frame. The output end of the electric push rod passes through the upper side wall of the support frame 2 and is fixedly connected to the upper side wall of the movable frame.

[0008] Furthermore, a motor is fixedly installed on one side of the movable frame, and the output end of the motor is fixedly connected to one end of the rotating rod through a coupling.

[0009] Furthermore, bearings are fixedly sleeved at both ends of the rotating rod, and a track is fixedly installed on the outer wall between the two bearings. Several rollers are uniformly rotatably connected to one end of the telescopic frame. The rollers are located inside the track and are in rolling connection with the inner wall of the track.

[0010] Furthermore, each drive frame has a strip-shaped hole at one end, and the rotating shafts at the left and right ends of the telescopic frame slide within the strip-shaped hole.

[0011] Furthermore, a baffle is fixedly installed on the rotating shaft of the telescopic frame, a protrusion is fixedly installed on the outer end of the baffle, a threaded post is fixedly installed on the outer end of the protrusion, and a nut is threadedly connected to the outer wall of the threaded post.

[0012] Furthermore, a fixing plate is fixedly installed at the upper end of the connecting rod. A fixing hole is provided on the side wall of the fixing plate, and the fixing plate is sleeved on the outer end of the protrusion through the fixing hole. The fixing plate is located between the nut and the baffle.

[0013] Furthermore, both the fixing hole and the protrusion are equilateral hexagons.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By placing the workpiece to be cut on the upper part of the die-cutting machine platform, the workpiece is cut by the die-cutting blade. When the position of the die-cutting blade needs to be adjusted, the motor is started, and the motor drives the rotating rod to rotate. When the rotating rod rotates, it drives the two threaded sleeves to move synchronously inward or outward through the threaded groove, thereby driving the telescopic frame to extend or retract, thereby driving the die-cutting blade to move. The two adjacent die-cutting blades are simultaneously extended or retracted at equal distances, which facilitates the adjustment of the position of the die-cutting blade.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a multi-position synchronous die-cutting machine, comprising: a platform 1, with support legs fixedly installed on all four sides of the lower end of the platform 1, a support frame 2 fixedly installed on the upper end of the platform 1, a movable frame 3 installed in the inner end of the support frame 2 that can be raised and lowered, both the support frame 2 and the movable frame 3 being U-shaped, a fixed cylinder 4 fixedly installed on the left and right sides of the upper end of the platform 1, the fixed cylinder 4 being located inside the support frame 2, and the lower left and right sides of the movable frame 3 being slidably inserted into the fixed cylinder 4, an electric push rod 5 fixedly installed on the upper end of the support frame 2, the output end of the electric push rod 5 passing through the upper side wall of the support frame 2 and fixedly connected to the upper side wall of the movable frame 3. Specifically, when the electric push rod 5 is started, it can drive the movable frame 3 to move in the vertical direction, while the lower end of the movable frame 3 slides in the inner end of the fixed cylinder 4 to guide the movable frame 3.

[0025] A rotating rod 6 is rotatably connected to the inner end of the movable frame 3. Threaded grooves 7 are symmetrically opened at both ends of the rotating rod 6. Threaded sleeves 11 are symmetrically threaded to both ends of the rotating rod 6 through the threaded grooves 7. A motor 8 is fixedly installed on one side of the movable frame 3. The output end of the motor 8 is fixedly connected to one end of the rotating rod 6 via a coupling. A drive frame 12 is fixedly installed on one side of each threaded sleeve 11. A telescopic frame 14 is installed between two drive frames 12. A slotted hole 13 is opened at one end of each drive frame 12. The rotating rods 13 at both ends of the telescopic frame 14... The shaft slides within the strip hole 13. Several connecting rods 21 are evenly and detachably installed at the lower end of the telescopic frame 14. Each connecting rod 21 has a die-cutting blade 23 installed at its lower end via a blade holder 22. When the motor 8 starts, it drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives two threaded sleeves 11 to move synchronously inward or outward through the threaded groove 7, thereby driving the telescopic frame 14 to extend or retract, thereby driving the die-cutting blade 23 to move, so that the two adjacent die-cutting blades 23 can be extended or retracted synchronously and equidistantly, thus adjusting the position of the die-cutting blade 23.

[0026] like Figure 5 and Figure 6 As shown, in some embodiments, bearings 10 are fixedly sleeved at both ends of the rotating rod 6. The inner wall of the bearing 10 and the outer wall of the rotating rod 6 are fixedly sleeved. A track 9 is fixedly installed on the outer wall between the two bearings 10. A plurality of rollers 24 are evenly rotatably connected to one end of the telescopic frame 14. The rollers 24 are located in the track 9 and are in rolling connection with the inner wall of the track 9. More specifically, when the rotating rod 6 rotates, it drives the telescopic frame 14 to move. At the same time, the rollers 24 move in the track 9 to guide and limit the telescopic frame 14, so that the telescopic frame 14 moves more stably.

[0027] like Figure 4 and Figure 6 As shown, in some embodiments, a baffle 15 is fixedly installed on the rotating shaft of the telescopic frame 14, and a protrusion 16 is fixedly installed on the outer end of the baffle 15. The protrusion 16 is equilateral hexagonal, and a threaded post 17 is fixedly installed on the outer end of the protrusion 16. A fixing plate 18 is fixedly installed on the upper end of the connecting rod 21. A fixing hole 19 is provided on the side wall of the fixing plate 18. The fixing hole 19 is equilateral hexagonal, and the size of the fixing hole 19 is slightly larger than the size of the protrusion 16. The fixing plate 18 is sleeved on the outer end of the protrusion 16 through the fixing hole 19. A nut 20 is threadedly connected to the outer wall of the threaded post 17. By screwing the nut 20, the fixing plate 18 is fixed between the baffle 15 and the nut 20. More specifically, by unscrewing the nut 20 from the threaded post 17 and then removing the fixing plate 18 from the protrusion 16, the die-cutting blade 23 can be removed, which facilitates the disassembly and assembly of the die-cutting blade 23.

[0028] When this device is working, the workpiece to be cut is placed on the upper end of the die-cutting machine platform 1, and the workpiece is cut by the die-cutting blade 23. When the position of the die-cutting blade 23 needs to be adjusted, the motor 8 is started. The motor 8 drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives the two threaded sleeves 11 to move synchronously inward or outward through the threaded groove 7, thereby driving the telescopic frame 14 to extend or retract, thereby driving the die-cutting blade 23 to move, so that the two adjacent die-cutting blades 23 can be extended or retracted synchronously and equidistantly, which facilitates the adjustment of the position of the die-cutting blade 23.

[0029] 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.
