[0032] The terms used in the embodiments of the present invention are only for the purpose of describing the specific embodiments and are not intended to limit the present invention.
[0033] See also Figure 1 , which illustrates a printing device 100, the printing device 100 includes a printer 1 and a cutter module 2.
[0034] The printer 1 can be a printer capable of printing on a paper roll, such as a receipt printer; the printer 1 includes an upper cover 11 and a base 12, and an internal paper feed channel (not shown in the figure) and a print head (not shown in the figure) arranged on the paper feed channel are formed between the upper cover 11 and the base 12; the end of the paper feed channel (not shown in the figure) is a paper output port, and the cutter module 2 is detachably mounted on the outer side of the paper output port of the printer 1; the paper output from the paper output port will pass through the cutter module 2 and complete cutting, and the cut paper will fall due to gravity.
[0035] See also Figure 2 , Figure 3 The cutter module 2 shown includes a cutter bracket 21, a cutter mechanism 22 mounted on the cutter bracket 21, an adapter 23 also mounted on the cutter bracket 21, a cutter paper guide 24, a cutter front cover 25, a connecting wire 26, an outlet line 27, and an electrostatic brush 28. The adapter 23 is connected to the cutter mechanism 22 via the connecting wire 26. The adapter 23 is connected to the printer main board via the outlet line 27.
[0036] See also Figure 4 , Figure 5 The cutter bracket 21 is an integral component and defines a front cavity 211, a side cavity 212 and a rear cavity 213. The cutter mechanism 22 can be locked in the front cavity 211 of the cutter bracket 21 by a plurality of fixing bolts, and the adapter 23 can be fixed in the rear cavity 213 of the cutter bracket 21. The cutter bracket 21 defines a paper outlet 20 for the passage of consumables, the front cavity 211 is partially located on the upper side of the paper outlet 20, and partially located on the lower side of the paper outlet 20, and the rear cavity 213 is entirely located on the lower side of the paper outlet 20. The cutter bracket 21 is provided with a first opening 214 that passes through the front cavity 211 and the side cavity 212, and a second opening 215 that passes through the side cavity 212 and the rear cavity 213.
[0037] See also Figure 6 The front cavity 211, the first opening 214, the side cavity 212, the second opening 215 and the rear cavity 213 are connected in sequence to form a wiring path for the connecting wire 26 to go from the cutter mechanism 22 to the adapter 23. The outlet wire 27 is arranged on the side of the adapter 23 away from the wiring path.
[0038] See also Figure 7 , which schematically shows the internal structure of the cutter mechanism 22. The cutter mechanism 22 includes a cutter housing 221 with an accommodating chamber 220 formed therein. The cutter drive mechanism 222, the movable blade 223 and the fixed blade 224 of the cutter mechanism 22 are all arranged in the accommodating chamber 220. The fixed blade 224 is arranged opposite to the movable blade 223 up and down, and the fixed blade 224 is located at the lower side of the paper outlet 20. The movable blade 223 can be driven by the cutter drive device 222 to reciprocate on the upper and lower sides of the paper outlet 20, thereby realizing the corresponding paper cutting action and reset action. When performing the paper cutting action, the movable blade 223 moves from the top to the bottom and passes through the paper outlet 20. The cutter drive mechanism 222 includes a motor 2221 and a transmission assembly 2222, and the transmission assembly can use a variety of transmissions such as gears and screws.
[0039] The cutter module 2 of the present invention can be installed at the paper output port of the printer in an inverted manner, and the movable blade 223 of the cutter module 2 moves from the upper side of the consumables to the fixed blade 224 at the lower side. Therefore, after the consumables are cut, they can fall automatically under the influence of gravity, effectively improving the undesirable phenomenon caused by electrostatic adsorption.
[0040] See also Figure 8 The housing 220 of the cutter mechanism 22 includes a rear wall 228, and the electrostatic brush 28 is fixed on the rear side surface of the cutter mechanism 22 and close to the upstream portion of the paper outlet 20. For example, the electrostatic brush 28 can be fixed on the rear wall 228 of the cutter mechanism 22 by a fixing block (not shown in the figure). Thus, the consumables output from the paper outlet of the printer first pass through the electrostatic brush 28, and then enter the paper outlet 20 to be output after cutting, so that the static electricity carried on the consumables is eliminated by the electrostatic brush 28.
[0041] The cutter paper guide 24 is fixedly connected to the cutter support 21 from the rear side and covers the cutter mechanism 22 and the electrostatic brush 28. Fig. 9 The cutter front cover 25 is fixed to the cutter bracket 21 from the front side and covers the front cavity 211, the side cavity 212 and part of the side wings of the cutter paper guide 24. In some embodiments of the present application, the cutter front cover 25 and the cutter paper guide 24 are both fixed to the cutter bracket 21 by bolts.
[0042] See also Fig.10 The base 121 of the printer 12 includes a bottom bracket 121. The cutter module 2 is configured to be installed at the front of the bottom bracket 121 in a pluggable manner in a vertical direction.
[0043] The front part of the bottom bracket 121 is provided with a mounting portion suitable for mounting the cutter module 2. The mounting portion includes a pair of fixing holes 122 and a pair of positioning grooves 123. The pair of positioning grooves 123 are located above the pair of fixing holes 122.
[0044] A pair of fixing barbs 216 and a pair of latches 217 adapted to the pair of fixing holes 122 , and a pair of positioning blocks 218 adapted to the pair of positioning grooves 123 are provided on the rear portion of the cutter bracket 21 .
[0045] In some embodiments of the present application, a pair of positioning blocks 218 are located in the middle of the rear of the cutter bracket 21, and a pair of fixing barbs 216 and a pair of latches 217 are located at the bottom of the rear of the cutter bracket 21. When the cutter module 2 is installed into the bottom bracket 121 in the vertical direction, each positioning block 218 enters the corresponding positioning groove 123, each fixing barb 216 and latch 217 are inserted into the corresponding fixing hole 122, and the fixing barb 216 will hook the edge of the hole of the fixing hole 122 from the bottom. With the cooperation of the pair of fixing barbs 216, the pair of latches 217 and the pair of fixing holes 122, the upward freedom of the cutter bracket 21 will be limited.
[0046] Therefore, the cutter module of the present application can be quickly assembled and disassembled without the aid of special tools.
[0047] Further, see Fig.11 The cutter module 2 provided in this embodiment is further provided with a first top opening 201 located on the cutter bracket 21 and a second top opening 202 located on the cutter front cover 25, and a spline 2223 is formed on one end of the output shaft of the motor 2221. After the cutter module 2 is assembled, the first top opening 201 and the second top opening 202 are aligned in the vertical direction, and the spline 2223 of the motor 2221 is exposed to the outside from the first and second top openings.
[0048] like Fig.12 As shown, if a paper jam or other fault occurs, the user can hold a long-handled tool 200 compatible with the spline 2223 and extend it into the cutter bracket 21 from the first top opening 201 and the second top opening 202 to drive the output shaft of the motor 2221 to rotate, so as to eliminate the paper jam. It can be understood that in other embodiments, the cutter module can be opened from the side, bottom, etc. The number of openings can be determined according to the specific structure of the cutter module, as long as the spline can be exposed for easy maintenance.
