[0031] The utility model provides a cutting device for a printer, which is used to be connected to a nozzle mechanism of the printer, and comprises a fixing seat 11, a handle 12 connected to one side of the fixing seat 11 and rotating with the fixing seat 11 as a rotation center, a cutting piece 14 connected to the handle 12 and used to extend into the fixing seat 11 to cut consumables, an elastic piece 15 connected between the fixing seat 11 and the handle 12, and a fixing block 13 connected to the printer and used to squeeze the handle 12. The fixing seat 11 is provided with a center hole 113 for the consumables to pass through, and the cutting piece 14 is arranged vertically to the center hole 113. When the handle 12 squeezes the fixing block 13, the handle 12 drives the cutting piece 14 to pass through the center hole 113. The fixing seat 11 is used to be installed on the nozzle mechanism of the printer, and the center hole 113 is used for the consumables to pass through. The handle 12 is used to install the cutting piece 14. The handle 12 is rotatably connected to the fixing seat 11. The elastic piece 15 is used to squeeze the handle 12 so that the handle 12 drives the cutting piece 14 away from the center hole 113 of the fixing seat 11, so as to prevent the printer from cutting during printing. The part 14 cuts the consumables. When the printer needs to replace the consumables or return the material, the printer drives the nozzle mechanism to move in the direction of the fixed block 13, and the nozzle mechanism drives the cutting device to move. When the handle 12 contacts the fixed block 13 and squeezes the handle 12, the handle 12 moves in the direction of the fixed seat 11, and the handle 12 squeezes the elastic part 15. The elastic part 15 is deformed, and the handle 12 drives the cutting part 14 to move in the direction of the center hole 113 of the fixed seat 11. When the cutting part 14 passes through the center hole 113, the cutting part 14 cuts the consumables, thereby facilitating the recovery or replacement of the consumables. It is convenient to replace the consumables without returning the consumables in the nozzle, thereby effectively avoiding the problem of thermal expansion and softening of the consumables, making the subsequent installation of consumables more convenient and quick. When the cutting part 14 finishes cutting the consumables, the handle 12 is away from the fixed block 13, the elastic part 15 loses the squeezing force and recovers the deformation and squeezes the handle 12 in the opposite direction, and the handle 12 drives the cutting part 14 away from the center hole 113 of the fixed seat 11. No manual operation is required, thereby reducing manual operation.

[0032] Please refer to Figure 5 , Figure 5 This is a three-dimensional diagram of a fixing base of a cutting device of a printer of the utility model, wherein the fixing base 11 comprises an upper shell 111 and a lower shell 112, wherein a first protrusion 116 is provided on one side of the upper shell 111, and a second protrusion 117 is provided on one side of the lower shell 112, and a placement groove for placing a cutting member 14 is formed between the first protrusion 116 and the second protrusion 117, wherein the cutting member 14 comprises a slider 141 movable in the placement groove and a cutter 142 connected to one side of the slider 141, and the placement groove is used to facilitate the slider 141 of the cutting member 14 to slide in the placement groove, thereby facilitating the cutter 142 to cut the consumables in the center hole 113 or move away from the center hole 113.

[0033] The second protrusion 117 is provided with a limiting groove 118 for limiting the moving direction of the slider 141 . The limiting groove 118 is used to limit the moving direction of the slider 141 to prevent the slider 141 from shifting when moving, so that the cutter 142 can cut the consumables more accurately.

[0034] Please refer to Figure 4 , Figure 4 This is a three-dimensional diagram of the handle of the cutting device of the printer of the utility model. A clearance groove 121 is provided on the side of the handle 12 close to the first protrusion 116. The first protrusion 116 is connected in the clearance groove 121. The handle 12 rotates with the first protrusion 116 as the rotation center. The clearance groove 121 facilitates the fixation of the handle 12 on the first protrusion 116. The handle 12 is also provided with a bolt 123. The handle 12 is connected to the first protrusion 116 through the bolt 123. The elastic member 15 is sleeved in the bolt 123. The two ends of the elastic member 15 are respectively abutted on the handle 12 and the first protrusion 116. The bolt 123 facilitates the installation of the elastic member 15. The elastic member 15 is used to squeeze the handle 12 and the first protrusion 116 to prevent the handle 12 from rotating toward the fixing seat 11, thereby preventing the cutter 142 from cutting the consumables.

[0035] In this embodiment, the elastic member 15 is a torsion spring, but is not limited to using only a torsion spring.

[0036] A strip hole 124 extending along the length direction of the handle 12 is provided on the side wall of the avoidance groove 121, and the slider 141 is slidably connected in the strip hole 124. The strip hole 124 is used to facilitate the movement of the slider 141 on the handle 12. When the slider 141 slides in the strip hole 124, the position of the slider 141 on the handle 12 can be adjusted, thereby ensuring that the slider 141 can move smoothly in the limit groove 118 during the rotation of the handle 12.

[0037] A positioning groove 122 for engaging the fixing block 13 is provided on one side of the handle 12 close to the fixing block 13. The positioning groove 122 is used to hook the fixing block 13 to prevent the handle 12 and the fixing block 13 from slipping when the handle 12 squeezes the fixing block 13, thereby further ensuring the stability of the cutter 142 when cutting the consumables.

[0038] A connector 114 connected to the nozzle mechanism is also provided at the bottom of the fixing base 11. The connector 114 is used to facilitate the connection of the fixing base 11 to the nozzle mechanism. A through hole 115 communicating with the center hole 113 is provided on the connector 114 to facilitate the passage of consumables into the nozzle mechanism for printing.

[0039] A relative fixing groove 119 is also provided on the peripheral side of the fixing seat 11 , and the fixing groove 119 is used to facilitate the operator to take the fixing seat 11 for installation and removal, and to prevent the operator from slipping when taking the fixing seat 11 when installing the seat.

[0040] Working principle:

[0041] When the cutting device is installed on the printer, the two ends of the connector 114 are respectively connected to the bottom of the fixed seat 11 and the top of the nozzle mechanism. Before printing, the printer passes the consumables through the center hole 113 of the fixed seat 11 and the through hole 115 of the connector 114, and connects the consumables that pass through the cutting device to the nozzle mechanism to print. When it is necessary to replace the consumables or return the material, the cutting device is moved to one side of the fixed block 13 and squeeze the fixed block 13. The handle 12 is attached to the fixed block 13 and squeezes the fixed block 13. Due to the action of the elastic member 15, the handle 12 moves toward the direction of the fixed seat 11 and squeezes the elastic member 15, and the elastic member 15 is deformed. During the movement of the handle 12, the handle 12 rotates with the first protrusion as the rotation center, and the handle 12 moves and drives the slider 141 to move in the limit groove 11. 8 moves toward the center hole 113, the slider 141 pushes the cutter 142 to pass through the center hole 113, and the consumables are cut off when the cutter 142 passes through the center hole 113. When the consumables are cut, the nozzle mechanism is away from the fixed block 13, and the nozzle mechanism drives the cutting device to move away from the fixed block 13. When the handle 12 is away from the fixed block 13, since the elastic member 15 loses the squeezing force of the handle 12, the elastic member 15 recovers its deformation and squeezes the handle 12 in the reverse direction, and the handle 12 pulls the slider 141 to move away from the fixed seat 11, thereby bringing the cutter 142 away from the center hole 113, and cutting the consumables from the top of the nozzle mechanism, which can effectively prevent the consumables heated and softened in the nozzle mechanism from being blocked when dragging the consumables, saves the channel for cleaning the movement of the consumables, speeds up the efficiency of installation and consumables, and is more convenient to use.

[0042] When the cutting device of the printer of the preferred embodiment squeezes the fixed block through the handle, the handle rotates toward the fixed seat, the handle squeezes the elastic part, the elastic part is deformed, and the handle drives the cutting part to move toward the center hole when rotating to cut the consumables in the center hole. Since the cutting device is connected to the nozzle mechanism, the consumables will not soften and expand after cutting, thereby preventing the consumables from adhering to the through hole where the consumables are placed, saving manual cleaning, speeding up the efficiency of subsequent installation of consumables, and being more convenient to use.

[0043] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
