The paper support roller 22 is a rubber covered roller, i.e., a roller that is shown covered with a rubber layer.
The sheet supporting roller driving motor 4 is provided with a speed reducer 5. The housing of the sheet supporting roller driving motor 4 is fixed to the housing of the decelerator 5. The motor shaft of the paper supporting roller driving motor 4 is connected with the input shaft of the speed reducer 5.

The bearing housing 61 is suspended below the suspension housing 62 by a suspension rod 65. The suspension rod 65 is sleeved with a connecting spring 66 between the bearing seat and the suspension seat. The two ends of the connecting spring 66 abut against the bearing seat 61 and the suspension seat 62, respectively. The lifting base driving mechanism 7 includes a screw 71, a threaded sleeve 72, and a lifting motor 73. The screw 71 extends in the vertical direction. The lower end of the screw rod 71 is rotatably hooked on the hanging seat 62. The screw rod 71 is screwed with the thread bush 72. The threaded sleeve 72 is rotatably connected within the sleeve mount 74. The sleeve seat 74 is fixedly connected with the frame 1. The lifting motor 73 is used for driving the threaded sleeve 72 to rotate.
Referring to fig. 3, the motor fixing nut 8 includes a circular ring-shaped nut body 81 and internal threads 82 provided on an inner peripheral surface of the nut body. Two through grooves 83 are formed in the inner peripheral surface of the nut body 81. The through groove 83 extends from one end to the other end in the axial direction of the motor fixing nut 8.

When the motor fixing nut 8 needs to be rotated, the through groove width adjusting bolt 84 is loosened until the through groove 83 is in a free state, i.e., in a state of every deformation, and then the motor fixing nut 8 is rotated. After the motor fixing nut 8 rotates in place, the through groove width adjusting bolt 84 is locked to enable the width of the through groove 83 to be reduced, and the internal thread 82 is tightly held on the thread of the mounting bolt as a result of reduction, so that looseness is not prone to being generated between the motor fixing nut 8 and the mounting bolt, and axial displacement of the tool apron is caused.
The second embodiment is different from the first embodiment in that:
referring to fig. 4, a power display mechanism 9 is also included. The power supply display mechanism 9 includes a light source 92 and a projection board 97. The light source 92 is mounted on the driving side of the chassis 1 through a heat sink 91. The projection plate 97 is mounted on the operating side of the gantry. The light source 92 is illuminated toward the projection plate 97. The light source 92 is a green laser diode. When the sheet supporting roller driving motor 4 is energized, the light source 92 emits light and projects onto the projection plate 97.
Referring to fig. 5, the power display mechanism 9 further includes a heating structure 93.
The heat sink 91 is provided with a light source mounting hole 911 and a heating structure mounting hole 912, a heat dissipation fin 913, and a heat sink mounting hole 914 which are communicated together. The light source mounting hole 911 is a circular hole. The heating structure mounting holes 912 are rectangular holes. The light source mounting hole 911 is through with the heating structure mounting hole 912, specifically, a circle where the light source mounting hole 911 is located extends into the heating structure mounting hole 912, that is, an intersecting manner. The opening width W of the portion where the light source mounting hole communicates with the heating structure mounting hole is less than a quarter of the circumference of the light source mounting hole 911. The heating structure mounting hole 912 is located at a side of the light source mounting hole 911 near the heat dissipation fin 913. The heat dissipation fins 913 are located on the surface of the heat sink 91. There are 17 fins of heat dissipating fins 913. The free ends 9131 of all the fins are on the same cylindrical surface. The extension directions, i.e., the depth directions, of the heat sink mounting hole 914, the light source mounting hole 911, and the heating structure mounting hole 912 are the same. The wall of the heat sink mounting hole 914 is provided with a notch 9141.
The light source 92 is cylindrical. The light source 92 is provided with a diode power supply lead-in pin 921.
The heating structure 93 includes a thermally conductive substrate 931 and a chip resistor 932 disposed on the thermally conductive substrate. The heat conductive substrate 931 is bonded in the heating structure mounting hole 912 in a flat manner by the heat insulating paste 933. The side of the thermally conductive substrate 931 remote from the light source 92 is disconnected from the walls of the heating structure mounting holes 912. The chip resistor 932 is disposed on a side of the thermally conductive substrate 931 remote from the light source 92. The heat conducting substrate 931 is provided with a heat conducting sleeve 934. The heat-conducting substrate 931 and the heat-conducting sleeve 934 are integrally formed. The heat conducting sleeve 934 is inserted into the light source mounting hole 911. The light source 92 is inserted through the heat conductive sleeve 934 and is suspended in the light source mounting hole 911. The linear expansion coefficient of the heat conducting sleeve 934 is greater than that of the heat sink 91, that is, the variation of the radial dimension generated by the heat conducting sleeve during expansion with heat and contraction with cold is greater than that generated by the light source mounting hole. When the temperature is above 25 ℃, the heat-conducting sleeve 934 and the light source mounting hole 911 are abutted together to realize the indirect abutment of the light source 92 and the light source mounting hole 911.
In use, the heat sink is fixed to a rotating shaft 97 (see fig. 3) of the motor through the heat sink mounting hole 914.
When the temperature is higher than 25 ℃, the heating structure 93 is not electrified, namely the chip resistor 932 is not electrified, the radial variation of the heat conduction sleeve 934 is larger than that of the laser light source mounting hole 911, so that the heat conduction sleeve 934 and the laser light source mounting hole 911 are abutted more closely to conduct better heat conduction. When the temperature is less than 25 ℃, the power is supplied to the chip resistor 932, the heat generated by the chip resistor 932 is transferred to the heat conduction substrate 931, the heat is transferred to the light source 92 to heat the light source 92 to a temperature not lower than 25 ℃, the radial reduction amount of the heat conduction sleeve 934 is greater than that of the laser light source mounting hole 911, a gap is generated between the heat conduction sleeve 934 and the laser light source mounting hole 911, the effect of reducing the heat conduction sleeve 934 to transfer the heat to the radiator 91 is achieved, the heat transferred by the heat conduction sleeve 934 of the heat conduction sleeve 934 can be transferred to the light source 92 more fully, and the effect of improving the heating effect is achieved.
The third embodiment is different from the second embodiment in that:
referring to fig. 6, one end of the heat conductive sleeve 934 and one end of the heat sink 91 are both sealingly abutted against the sealing plate 94, i.e., both the heat conductive sleeve and the heat sink are slidable relative to the sealing plate 94. The other end of the heat conducting sleeve 934 and the other end of the heat sink 91 are hermetically connected together by an annular reservoir 95. The annular reservoir 95 is filled with a heat insulating liquid which keeps the annular reservoir 95 in an elastically expanded state. When the temperature is below 25 ℃, a sealing cavity 96 is formed among the heat conducting sleeve 934, the sealing plate 94, the heat radiator 91 and the annular liquid storage bag 95. The sealed chamber 96 communicates with the annular reservoir 95.
The annular reservoir 95 is positioned in use above the sealed cavity 96 of the annular reservoir 95. When being less than 25 ℃ the shrinkage effect can lead to producing the clearance and making sealed chamber 96 appear between heat conduction cover and the light source mounting hole, and the adiabatic liquid in annular liquid storage bag 95 flows to sealed chamber 96 under the elastic shrinkage effect of gravity and annular liquid storage bag this moment, plays further to reduce the volume that heat conduction cover 934 transmitted for radiator 91 for the heating effect further promotes. When the temperature is higher than 25 ℃ or 30 ℃ and heat dissipation is needed, the heat conduction sleeve and the light source mounting hole are tightly pressed together under the action of thermal expansion, so that the sealing cavity 96 disappears, and the heat insulation liquid in the sealing cavity 96 is squeezed back into the annular liquid storage bag 95 again to be stored.
