Detailed Description

In order to make the present invention more comprehensible to those skilled in the art, the paper saving machine of the present invention is described in detail with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, a paper saving machine comprises a housing 1, and a roller 2 and a paper saving member 3 arranged in the housing.

The housing 2 is enclosed by a left side plate 11, a right side plate 12 and a rear side plate 13, and a top cover can be preferably added on the roller. The housing 1 is provided with a roll paper frame 15, the roll paper frame 15 is preferably formed by surrounding a plurality of support rods 151 fixed on the left side plate 11 and the right side plate 12, and the shape of the roll paper frame 15 corresponds to the shape of roll paper and is an arc hollow groove.

One side of the housing 1 far from the rear side plate 13 is provided with a paper outlet 16, and the front end of the paper outlet 16 is provided with a paper clamping groove 17. The paper jam groove 17 is composed of two parallel connecting rods 171 fixed to the left side plate 11 and the right side plate 12, one of which is vertically adjustable and the other is horizontally adjustable. Preferably one adjacent the outer side is adjustable up and down and one adjacent the rear side panel 12 is adjustable back and forth. The adjustment is achieved by screwing the connecting rod 171 in different positions of the chute.

The roller 2 is installed in the housing 1 through a central shaft 21 fixed on the left side plate 11 and the right side plate 12 and can rotate around the central shaft 21; the surface of the roller 2 is not smooth, and a material with the texture like sand paper is preferably adopted as the surface; an elastic stopper 22 parallel to the central shaft 21 is fixed to one side edge of the drum 2. The resilient stop 22 is compressible upon depression. As an alternative preferred solution, the roller 2 has a retraction slot at one side edge, and after pressing the elastic block 22, the elastic block can retract into the retraction slot, and after retraction, the edge surface is flush. When the pressing force is removed, the elastic stopper 22 protrudes from the retraction groove due to the elastic force.

As shown in fig. 2 and 3, with reference to fig. 4, the paper saving member 3 includes a paper feeding plate 31, a narrow arm 32 and a wide arm 33 connected in sequence, the narrow arm 32 and the wide arm 33 are curved in an arc shape, and the free end of the wide arm wider than the narrow arm is bent upward to form a stopping groove 34, and the stopping groove 34 is close to the side of the roller 2 where the elastic stopper 22 is disposed. The end of the paper sheet 31 near the paper outlet 16 is bent upward to form a paper cutting surface 311, and the edge of the paper cutting surface 311 bent upward is preferably serrated. The two sides of one end of the paper feeding plate 31 close to the rear side plate 13 are respectively connected with the left side plate 11 and the right side plate 12, the connection part becomes a fulcrum 312, and the paper saving piece 3 becomes a lever and can rotate along the fulcrum 312 within a certain range; the wide arm 33 extends backward along the left side plate 11, so that when the roller 2 rotates, the elastic stopper 22 at the edge of the roller 2 can push the wide arm 33 to press downward and drive the paper feeding plate 31 to tilt upward to be close to the paper outlet 16.

The button 111 is provided outside the left side plate 11, and the button 111 is correspondingly pressed to separate the elastic stopper 22 from the stopping groove 34 of the wide arm 33.

The roll paper is placed on the roll paper holder 15, one end of the roll paper is pulled up to pass around the drum 2 along the upper surface of the drum 2, and is pulled out to the paper feeding plate 31 from the lower surface of the drum 2, enters the paper jam groove 17 of the paper outlet 16 along the cut paper surface 311 end of the paper feeding plate, and is pulled out to the housing 2.

The use of the paper-saving machine is explained as follows:

when paper is needed, the roll paper is pulled outwards by force from the paper jam groove 17, in the process of pulling outwards, the surface of the roller 2 is rough, so due to the effect of friction force, the roll paper on the surface of the roll paper can drive the roller 2 to rotate anticlockwise along the central shaft 21, meanwhile, the elastic stop 22 at the edge of the roller 2 also rotates anticlockwise due to the rotation of the roller 2, and after the roll paper rotates to a position horizontal to the central shaft 21, the roll paper continuously rotates, and the wide force arm 33 close to the left side plate 11 is continuously pressed downwards. Based on the lever principle, the wide force arm 33 drives the paper feeding plate 31 to tilt upwards along the fulcrum 312 through the narrow force arm 32, and the paper cutting surface 311 of the paper feeding plate 31 is clamped into the paper clamping groove 17, and the paper on the paper cutting surface 311 is clamped in the paper clamping groove 17.

At this time, the elastic stop 22 at the edge of the roller 2 also just rotates to the lowest end, and is clamped in the stopping groove 34 at the joint of the wide force arm and the narrow force arm, so that the roller 2 is stopped from continuously rotating to feed paper outwards, and the paper is continuously pulled outside and is still pulled. The paper cutting surface 311 cuts the paper by the cooperation of the paper jam groove 17 and the external tension. And finishing one-time paper taking.

If the paper is to be taken out continuously, the button 111 outside the left side plate 11 is only pressed, the button 111 pushes the elastic stop 22 to retract, so that the elastic stop 22 is separated from the stopping groove 34, and at this time, the paper feeding plate is heavier and falls back to the original position under the action of gravity (see the dotted line shown in fig. 4), so that the wide force arm is driven to tilt up again to enter the next paper taking cycle.

Each time of paper taking, the button 111 needs to be pressed once, and then the rolled paper is pulled, so that the purpose of saving the paper is achieved.

The inventive concept is explained in detail herein using specific examples, and the above description of the embodiments is only used to help understand the core idea of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
