[0026] DETAILED DESCRIPTION Figure 5 Figure 1 As CONCRETE EMBODIMENT

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings, obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0028] As Figures 1 to 5 ​​As shown, a printer paper feeder comprises a frame 1, a paper bin, a conveying belt 2, an ejector 5 and a chute 4 are installed on the frame 1.

[0029] The frame 1 has a top mounting surface, and a slot is arranged in the center of the top mounting surface. As a preferred example, a height adjusting seat 12 is further installed on the bottom of the frame 1 for adjusting the overall height. The height adjusting seat 12 is located at the rear of the bottom of the frame 1, and the height is adjusted by screwing.

[0030] The paper bin is located on the top mounting surface. A front vertical plate 16 is arranged in front of the paper bin, and a paper outlet is arranged in the bottom center of the front vertical plate 16. The paper bin can accommodate at least 100 printing papers 100, thereby meeting the printing demand of large printing volume. As a preferred example, the paper bin can accommodate different types of printing papers 100, such as A4, A5, A6 and 6-inch, 7-inch photo paper, etc. Therefore, the size of the paper bin can be adjusted according to the paper size. Specifically, the paper bin has two width-adjustable paper bin side plates 13, which are vertically installed on the top mounting surface in a plug-in manner, i.e. a plurality of insertion slots are arranged on the top mounting surface, and the distribution direction of the insertion slots is consistent with the width direction of the printing paper 100. By inserting the bottom insertion plates of the two paper bin side plates 13 into different insertion slots, the width of the two paper bin side plates 13 is changed, thereby realizing the storage and accommodation of different specifications of printing papers 100.

[0031] As a preferred example, a first paper sensor 10 for detecting the lack of printing paper 100 in the paper bin is further installed on the frame 1. The first paper sensor 10 is installed on the top mounting surface, and when the printing paper 100 in the paper bin is completely output, the first paper sensor 10 generates a signal to the controller, thereby issuing an alarm to remind the user to replenish the printing paper 100.

[0032] The conveying belt 2 is located in the slot below the paper bin, and the top surface of the conveying belt 2 is higher than the top mounting surface, thereby being able to convey the printing paper 100 forward. The front end of the conveying belt 2 extends to the front of the paper bin, so that the printing paper 100 can be output from the paper outlet. Obviously, the conveying belt 2 includes a motor and a driver, and is controlled by the controller. A power connector and a key 15 are installed on the frame 1, and the above technology belongs to the conventional means, so it is not described in detail.

[0033] The slide 4 is installed on the front vertical plate 16 through two slide arms 14, which are also installed in the form of insertion. The width between the two slide arms 14 can be adjusted by changing the installation position of the two slide arms 14, so as to adapt to different specifications of the printing paper 100. The slide 4 is located below the paper pressing plate 3, the upper end of the slide 4 extends to the front of the paper pressing plate 3, and the lower end of the slide 4 extends obliquely to the rear. The upper end of the slide 4 is hingedly installed at the front end of the slide arm 14, and the setting angle of the slide 4 is determined according to the paper inlet of the printer. After the printing paper 100 is output from the paper outlet, the printing paper 100 falls into the slide 4 and then slides along the surface of the slide 4 to the paper inlet of the printer.

[0034] As a preferred example, the second paper sensor 11 for detecting the lack of printing paper 100 in the slide 4 is also installed on the slide 4. When the printing paper 100 in the slide 4 is out of paper, the second paper sensor 11 generates a signal to the controller, and the controller controls the conveying belt 2 to convey the printing paper 100 into the slide 4, so as to realize automatic paper feeding.

[0035] The ejector 5 is installed on the frame 1 and located at the bottom of the paper bin close to the rear end of the printing paper 100. The function of the ejector 5 is to lift the rear end of the printing paper 100 upward, so that the printing paper 100 becomes loose, thereby reducing the paper outlet friction and realizing fast paper outlet. The ejector 5 can be a rudder or an electromagnetic push rod. When the printing paper 100 is conveyed, the ejector 5 is set to operate regularly and repeatedly, so as to realize continuous paper outlet. The operating frequency of the ejector 5 is set according to the actual paper outlet speed.

[0036] As a preferred example, the paper pressing plate 3 is also installed on the frame 1, which is located in front of the paper bin. Specifically, the paper pressing plate 3 is installed on the front vertical plate 16 and has an overall obtuse angle bending structure, the rear section of which is horizontally arranged, and the front section of which is obliquely arranged downward. The front end edge of the paper pressing plate 3 is located below the plane A, which is tangent to the front end outer surface of the conveying belt 2 and intersects with the contact position of the printing paper 100 and the slide 4. In this way, when the front end of the printing paper 100 contacts the slide 4, the printing paper 100 will be bent, thereby increasing the contact force. It can be seen that the function of the paper pressing plate 3 is to provide a downward pressure on the printing paper, so as to increase the friction between the printing paper and the conveying path, thereby avoiding the deviation of the printing paper.

[0037] As a preferred example, the clamping arm 6 for clamping the printer is also installed on the frame 1. The clamping arm 6 is hingedly installed at the front end of the frame 1 and used for clamping the printer.

[0038] As a preferred example, the adjustable page plate 7 is also installed on the frame 1, which can change the paper output quantity of the paper outlet. Specifically, the adjusting screw 8 and the spring 9 sleeved on the outer periphery of the adjusting screw 8 are also installed on the frame 1. Specifically, the adjusting screw 8 is installed in the nut on the front vertical plate 16. The top surface of the page plate 7 abuts against the bottom surface of the head of the adjusting screw 8, and the bottom surface abuts against the top end of the spring 9. Rotating the adjusting screw 8 downward can press the page plate 7 downward, thereby reducing the effective opening of the paper outlet and reducing the paper output quantity.

[0039] Working process and principle of the present application

[0040] The present application is installed on the printer, the clamping arm 6 clamps one side edge of the printer, and then the printing paper 100 is placed in the paper bin. After preparation, the key 15 is pressed. The ejector 5 works to lift the rear end of the printing paper 100, and then the conveying belt 2 works to output the lowermost printing paper 100 from the paper outlet. The front end of the printing paper 100 is conveyed to the slide 4, and then the middle part is bent downward due to the action of the paper pressing plate 3. When the rear end of the printing paper 100 leaves the conveying belt 2, the end falls under the action of gravity and contacts the slide 4, and then the whole printing paper 100 slides along the surface of the slide 4 to the paper inlet of the printer. When the printer works to output the printing paper 100, the second paper sensor 11 in the slide 4 detects the lack of paper and generates a signal, and the controller controls the conveying belt 2 to convey the new printing paper 100 to the slide 4 again for the next printing task.
