[0030] The utility model provides a buffer mechanism of a printer, which is used to be connected with a consumable material feeder, and includes a housing 11, a control panel 12 located in the housing 11, and a sliding device 13 slidably connected in the housing 11 and located on one side of the control panel 12. The control panel 12 is provided with a first sensing member 121. The housing 11 is provided with a feed port 111 for feeding consumable materials, a discharge port 115 communicating with the feed port 111, and a placement groove 114 located at one end of the housing 11 and communicating with the discharge port 115. The sliding device 13 includes a slider 131 that can slide in the placement groove 114 and communicate with the discharge port 115, and two ends are respectively connected to the housing 11 and the slider 131. The elastic member 132 on the slider 131 and the magnetic member 133 connected to the slider 131, the magnetic member 133 is opposite to the first sensing member 121, when the consumable pushes the slider 131 to slide, the first sensing member 121 is used to sense the sliding distance of the magnetic member 133, the buffer mechanism is used to connect with the consumable feeder, when the consumable is discharged too slowly, the buffer mechanism transmits a signal to the feeder to speed up the consumable feeding speed, when the consumable is discharged too quickly, the buffer mechanism transmits a signal to the feeder to reduce the consumable discharge speed, the housing 11 is used to install the control panel 12 and the sliding device 13, the control panel 12 is used to sense the moving distance of the sliding device 13 and thereby transmit a signal to the feeder.

[0031] When printing, first, the consumables are passed through the feed port 111 and out of the feed port 115, and the slider 131 is connected to the feed port 115, and the consumables passed through the feed port 115 are passed into the slider 131, and the consumables passed through the slider 131 are connected to the printer. The printer pulls the consumables to move when printing. When the consumables in the buffer mechanism are discharged too fast, the consumables are in the slider 131 and push the slider 131 to move, and the slider 131 slides in the placement groove 114. Since the elastic member 132 is connected to the slider 131, the elastic member 132 prevents the slider 131 from moving when the slider 131 moves. 131 is separated from the shell 11. When the slider 131 moves, the magnetic member 133 is connected to the slider 131 and moves with the slider 131. When the first sensing member 121 senses that the magnetic member 133 has moved to a specified distance, the control board 12 transmits a signal to the feeder. The feeder slows down the feeding speed of the consumables according to the signal of the control board 12. On the contrary, when the magnetic member 133 does not move, the feeder speeds up the feeding speed of the consumables to prevent the printer from running out of material during printing. Through the above structure, the feeding speed of the consumables can be effectively synchronized, and the printed products are more perfect.

[0032] A first fixing groove 1311 for placing the magnetic member 133 is provided on one side of the slider 131 close to the control board 12. The first fixing groove 1311 is used to place the magnetic member 133. When the slider 131 moves, the magnetic member 133 can move with the slider 131. In this embodiment, the magnetic member 133 is a magnet, but is not limited to using only magnets.

[0033] A second fixing groove 113 is also provided in the shell 11, which is located on one side of the placement groove 114 and communicated with the placement groove 114. The elastic member 132 is located in the second fixing groove 113. The second fixing groove 113 is used to place the elastic member 132. The second fixing groove 113 is located on one side of the placement groove 114 to facilitate the connection between the elastic member 132 and the slider 131. In this embodiment, the elastic member 132 can be an elastic swing arm or a spring, but is not limited to using only elastic swing arms or springs.

[0034] A fixing column 1131 for fixing the elastic member 132 is disposed in the second fixing groove 113 . The fixing column 1131 is connected to the second fixing groove 113 , so that the elastic member 132 can be conveniently clamped on the fixing column 1131 or the fixing column 1131 can conveniently fix the elastic member 132 .

[0035] An opening is provided on one side of the placement slot 114 close to the control board 12 , and the opening is used to facilitate the first sensing element 121 to sense the position of the magnetic element 133 .

[0036] The shell 11 is provided with a plurality of feed ports 111 for placing consumables of different colors or different specifications. It is not necessary to replace the consumables in the buffer mechanism when replacing one consumable, which is more convenient to use.

[0037] One side of the shell 11 is also provided with a plurality of stepped and inclined installation steps, and a plurality of feed ports 111 are respectively located on the installation steps. The stepped and inclined installation steps are used to reduce the volume of the shell 11 to prevent the volume of the shell 11 from being too large, and are convenient for carrying or transportation.

[0038] The multiple feed ports 111 are all provided with channels 112 for the movement of consumables, and the channels 112 are all connected to the discharge port 115. The multiple feed ports 111 have their own channels 112 to prevent different types of consumables from sharing one channel 112 and causing confusion, which is more convenient when installing consumables.

[0039] A through slot communicating with the control board 12 is provided in the channel 112, and a second sensing element 122 is provided at a position on the control board 12 opposite to the through slot. The through slot is used for the channel 112 to communicate with the control board 12, and a second sensing element 122 is further provided at a position on the control board 12 opposite to the through slot, which is further used to monitor the discharge of the consumables and prevent the consumables from being cut off in the buffer mechanism. In this embodiment, the first sensing element 121 and the second sensing element 122 can be Hall sensors, but are not limited to using only Hall sensors.

[0040] Working principle:

[0041] When printing, first, the consumables of the consumable feeder enter and exit from the feed port 111 of the shell 11 and pass through the channel 112 from the discharge port 115. The consumables after passing through pass through the slider 131, and the consumables passing through the slider 131 are connected to the printer. When the printer is printing, the printer pulls the consumables to move, and the consumables enter the printer from the slider 131. When the consumables in the slider 131 do not squeeze the slider 131, the first sensing element 121 does not sense the movement of the magnetic element 133, and the control board 12 transmits a signal to the consumable feeder, and the consumable feeder speeds up the feeding speed of the consumables. When too much consumables enter the shell 11 and squeeze the slider 131, the slider 131 moves in the placement slot 114 in the direction away from the shell 11. Due to the action of the elastic element 132, the elastic element 132 The elastic member 132 can prevent the slider 131 from separating from the shell 11. The elastic member 132 is deformed when the slider 131 moves. Furthermore, when the slider 131 moves, the magnet on the slider 131 moves with the slider 131. When the magnetic member 133 moves to a limited distance, the first sensing member 121 feeds back to the control board 12, and the control board 12 feeds back a signal to the feeder. The feeder reduces the feeding speed of the consumables so that the feeding speed of the feeder is synchronized with the printing efficiency of the printer. When the consumables do not squeeze the slider 131, the elastic member loses the squeezing force and slowly recovers the deformation. While recovering the deformation, the slider 131 is pulled to reset. On the one hand, it can effectively ensure the integrity of the products printed by the printer. On the other hand, it can also effectively prevent the consumables from being transported too fast and contacting the ground.

[0042] The buffer mechanism of the printer of this preferred embodiment is achieved by installing the consumables in the feeder in the buffer mechanism and connecting it to the printer. When the printer pulls the consumables to move and the first sensing component does not sense the movement of the magnetic component, the control board transmits a signal to the feeder to speed up the conveying speed of the consumables. When the consumables in the slider push the slider to move, the magnetic component follows the slider to move, the first sensing component senses the movement of the magnetic component and feeds back to the control board, and the control board transmits a signal to the consumable feeder to reduce the speed of conveying the consumables, thereby keeping the feeder conveying the consumables synchronous with the printer extrusion.

[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.
