Description

Technical Field

[0001] The utility model discloses a printing slitting machine with adjustable spacing, and relates to the technical field of slitting machines. Background Art

[0002] Printing slitter machines are common equipment in the printing industry, used to cut large-format printed materials or continuous rolls into desired sizes or lengths for subsequent processing or use. Printing slitter machines play a key role in the printing industry, improving production efficiency and product quality while also enhancing production flexibility and diversification.

[0003] During processing, the blade position and pressure can be adjusted as needed to accommodate different materials and cutting requirements. Adjusting the blade position typically involves using a tool (usually a wrench or screwdriver) to loosen the blade's retaining screws. After adjusting the blade's position, the tool is used to retighten the blade's retaining screws to ensure the blade is securely fixed in place. This method of adjusting the blade is time-consuming and time-consuming, leading to the need for a printing slitting machine with adjustable spacing to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Specific implementation cases:

[0019] Such as Figure 1As shown in the figure, a slitter for printing with adjustable spacing includes a frame 1. A pressing mechanism 2 is installed on the frame 1 for pressing the printing paper roll. A feeding mechanism 6 is arranged below the pressing mechanism 2 for transporting the printing paper roll. A blade holder 4 is installed on the frame 1. A tool holder 3 is installed below the blade holder 4. A paper winding mechanism 5 is also installed on the frame 1. The driving mode of the blade holder 4 is motor drive. Gears (not marked in the figure) are installed at both ends of the blade holder 4. Double gears (not marked in the figure) are installed at both ends of the tool holder 3. The gears are meshed with the double gears. The driving mode of the double gears is motor drive;

[0020] Among them, the blade holder 4 is driven by a motor drive seat to move linearly up and down. Double gears are installed at both ends of the tool holder 3 and are driven by a motor to rotate, driving the gears installed at both ends of the blade holder 4 to rotate in the opposite direction;

[0021] When the device is operating, the operator passes the processing paper through the feeding mechanism 6 and through the pressing mechanism 2, then through the blade holder 4 and the tool holder 3, and finally winds it onto the paper winding mechanism 5. After fixing the paper, the pressing mechanism 2 presses the paper (which is prior art and will not be elaborated here). Start the motor to drive the blade holder 4 and the tool holder 3 to rotate, and lower the blade holder 4 to start slitting the paper;

[0022] As Figure 2 shown in the figure, the blade holder 4 includes a threaded shaft 31. A shaft sleeve 33 is installed on the threaded shaft 31. A fixing hole 331 is provided on the shaft sleeve 33 for fixing after adjusting the threaded shaft 31. Four groups of connecting rods 32 are installed on the shaft sleeve 33. A contact plate 36 is rotatably installed on the connecting rod 32. The outer side of the contact plate 36 is an arc surface. A threaded shaft sleeve 35 is installed on the threaded shaft 31. A rotating shaft 34 is fixedly installed on the threaded shaft sleeve 35. A connecting frame 37 is rotatably installed on the threaded shaft sleeve 35. The horizontal position of the connecting frame 37 is fixed. The connecting frame 37 is rotatably connected with the connecting rod 32. The connecting rods 32 installed on the shaft sleeve 33 and the connecting rods 32 installed on the connecting frame 37 are symmetrically distributed. A tool rest 38 is installed on the outer side of the contact plate 36;

[0023] The tool holder 3 includes a threaded shaft 31, on which a sleeve 33 is mounted. A fixing hole 331 is provided on the sleeve 33 for fixing the threaded shaft 31 after adjustment. Four groups of connecting rods 32 are mounted on the sleeve 33. A resistance plate 36 is rotatably mounted on the connecting rod 32. The outer side of the resistance plate 36 is an arc-shaped surface. A threaded sleeve 35 is mounted on the threaded shaft 31. A rotating shaft 34 is fixedly mounted on the threaded sleeve 35. A connecting frame 37 is rotatably mounted on the threaded sleeve 35. The connecting frame 37 is fixed in a horizontal position and is rotatably connected to the connecting rod 32. The connecting rod 32 mounted on the sleeve 33 and the connecting rod 32 mounted on the connecting frame 37 are symmetrically distributed. A tool holder 39 is mounted on the outer side of the resistance plate 36.

[0024] The position of the blade holder 4 is opposite to that of the blade support 3. A blade (not shown) is mounted on the blade holder 4. The blade contacts the side surface of the blade support 3.

[0025] The threaded sleeve 35 is fixed in position, and the threaded shaft 31 can move forward or backward by rotating, and its position can be fixed by the fixing hole 331;

[0026] When adjusting the spacing between the tool holders 38, the operator unscrews the bolt in the fixing hole 331, rotates the gear to drive the threaded shaft 31 to rotate and move it backward, and presses the end of the connecting rod 32 connected to the contact plate 36 downward, driving the contact plate 36 to retract inward, and the tool holder 38 is loosened. The operator adjusts the tool holder 38 to the specified spacing, rotates the gear to make the threaded shaft 31 move forward, and the end of the connecting rod 32 connected to the contact plate 36 extends upward, driving the contact plate 36 to expand outward until the tool holder 38 is clamped. Then the operator tightens the bolt in the fixing hole 331 in the sleeve 33 to fix the position of the threaded shaft 31, completing the step of adjusting the spacing between the tool holders 38.

[0027] The process of adjusting the spacing between the tool holders 39 is the same as the process of adjusting the spacing between the tool holders 38, so no further details will be given here;

[0028] To sum up, the threaded shaft 31 can be rotated forward or backward to drive the end of the connecting rod 32 connected to the contact plate 36 to be pressed downward or extended upward, driving the contact plate 36 to retract inward or expand outward, thereby clamping the tool holder 38. The operator can then manually adjust the position of the tool holder 38 and the tool seat 39 to achieve the function of easily adjusting the spacing of the slitting machine. The position of the threaded shaft 31 can be fixed by the bolt in the fixing hole 331 in the sleeve 33, thereby enhancing the stability of the mechanism.
