Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The paper feeding assembly of the printer shown in fig. 1 comprises two L-shaped brackets 1 which are matched with each other, namely an inner L-shaped bracket 101 and an outer L-shaped bracket 102;
the inner L-shaped bracket 101 is arranged inside the outer L-shaped bracket 102; the tail parts 1 of the two L-shaped brackets are hinged with each other through a hinge shaft 103; the top of the outer L-shaped bracket 102 is provided with a pinch plate 104 extending to the inner side, and the top of the inner L-shaped bracket 101 is limited by the pinch plate 104; the glue roller shaft 2 is supported by the L-shaped bracket 1.
The inner end of the inner L-shaped bracket 101 is provided with a shifting piece 105 extending inwards.
The two glue roller shafts 2 are arranged on the L-shaped support 1, and the two glue roller shafts 2 are vertically opposite to each other.
The inner L-shaped bracket 101 has a two-section structure, and the two-section L-shaped brackets 1 are connected with each other.
Longitudinal connecting plates 3 are respectively arranged on the brackets on the two sides of the joint of the inner L-shaped bracket 101; the top parts of the connecting plates 3 are hinged with each other.
The corresponding positions of the two connecting plates 3 are respectively provided with a semicircular notch groove, and when the two connecting plates 3 are butted together, the two semicircular notch grooves form a complete round hole; the lower part of the connecting rod 3 is respectively provided with a 90-degree fan-shaped notch groove, the upper part of the corresponding outer L-shaped bracket 102 is provided with a semicircular notch groove, and the two 90-degree fan-shaped notch grooves and the semicircular notch groove on the outer L-shaped bracket 102 form a complete round hole; the two rubber roll shafts 2 are respectively arranged in the two round holes.
When the rubber roller fixing device is used, the rubber roller shaft at the lower part is firstly placed into the semicircular notch groove on the L-shaped support at the outer side, then the connecting plate is opened, the other rubber roller shaft is installed into the corresponding notch groove, then the L-shaped support at the inner side is pressed downwards, and the front part of the L-shaped support at the inner side is buckled into the buckle plate to realize fixing.
