Description

Technical Field

[0001] This utility model relates to the technical field of paper sorting devices, specifically to a stacked paper sorting device. Background Technology

[0002] In paper product manufacturing, the amount of paper stacked in the preparation silo is constantly changing due to the continuous addition of new paper. This also causes fluctuations in the pressure applied to the bottom layer of paper. Because paper has a certain degree of flexibility and elasticity, the thickness of the paper stacked below the preparation silo varies with the pressure, leading to errors in the fixed-height feeding of paper in the next process. For example, if there is a large amount of paper in the preparation silo, the paper at the bottom of the feeding end experiences greater pressure. Under this greater pressure, the lower stack of paper is more compact, resulting in a larger quantity of paper being fed according to the specific stacking height standard, and a thicker overall thickness before reaching the next process. Conversely, if there is a small amount of paper in the preparation silo, the paper at the bottom of the feeding end experiences less pressure. Under this less pressure, the lower stack of paper is more fluffy, resulting in a smaller quantity of paper being fed according to the specific stacking height standard, and a thinner overall thickness before reaching the next process. Therefore, improving the consistency of the overall thickness of the paper stacked below the preparation silo is a pressing issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a stacked paper distribution device to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stacking paper sorting device includes a telescopic drive device and a mounting block. A sliding plate is mounted on the lower end of the telescopic drive device, extending outwards at an angle. The sliding plate includes a first sliding plate and a second sliding plate symmetrically arranged, with notches facing each other on the first and second sliding plates, the notches located at the upper part of the first and second sliding plates. The mounting block is disposed at the end of the telescopic rod of the telescopic drive device. A first pin and a second pin are laterally slidably connected to the mounting block. A crossbar is provided at the outer end of the first and second pins. A spring is connected between the middle of the crossbar and the mounting block. The two ends of the crossbar are sliding ends, which, under the action of the spring, rebound from the inside of the sliding plate to the outside of the sliding plate from the corresponding notch.

[0006] In this technical solution, the first and second sliding plates are tilted. During the extension and retraction of the telescopic rod, the first and second pins are connected to the crossbar and move forward and backward along the mounting block. This allows the first and second pins to insert into and exit the gaps between the stacked papers. Combined with the retraction of the telescopic rod, the upper stacked papers are lifted, thus separating the upper and lower stacked papers. Even when there are many upper stacked papers, separating them prevents the upper stacked papers from putting pressure on the lower stacked papers during discharge. This solves the problem of large discharge thickness errors in the lower stacked papers caused by the heavy pressure of the upper stacked papers.

[0007] Furthermore, in order to better control the movement of the mounting block, the telescopic drive device is a cylinder.

[0008] Furthermore, to improve the service life of the steel needles and crossbar, both the first and second inserts are steel needles, and the crossbar is a steel rod. Preferably, the steel needles and steel rod are welded together.

[0009] Furthermore, to facilitate adjustment of the length of the steel needle, the steel needle includes a pin and a screw. The pin is slidably engaged with the mounting block, and the screw is threadedly connected to the internal threaded hole of the pin. The end of the screw is ground into a needle tip.

[0010] Furthermore, to facilitate the installation and fixation of the skateboard, the skateboard includes a connecting plate. The first skateboard, the second skateboard, and the connecting plate form a door shape in the orthographic projection state. The connecting plate is fixedly connected to the telescopic drive device by fastening screws.

[0011] The beneficial effects of this utility model are as follows: In this technical solution, the first and second sliding plates are inclined. During the extension and retraction of the telescopic rod, the first and second pins are connected to the crossbar and the first and second pins, enabling the first and second pins to move forward and backward along the mounting block. This allows the first and second pins to insert into and exit the gap between the stacked papers. Combined with the retraction of the telescopic rod, the upper stacked papers are lifted, thus separating the upper stacked papers from the lower stacked papers. Even when there are many upper stacked papers, separating the upper stacked papers prevents them from putting pressure on the lower stacked papers during discharge, thereby solving the problem of large discharge thickness errors in the lower stacked papers caused by the heavy pressure of the upper stacked papers.

[0029] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0030] Example 1:

[0031] like Figures 1-16 As shown, this embodiment provides a stacked paper sorting device, including a telescopic drive device 1 and a mounting block 2. A sliding plate is installed at the lower end of the telescopic drive device 1. The sliding plate extends outward at an angle. The sliding plate includes a first sliding plate 3 and a second sliding plate 4 arranged symmetrically. The first sliding plate 3 and the second sliding plate 4 are provided with notches 5 facing each other. The notches 5 are located at the upper position of the first sliding plate 3 and the second sliding plate 4. The mounting block 2 is set at the end of the telescopic rod 6 of the telescopic drive device 1. A first pin 7 and a second pin 8 are slidably connected to the mounting block 2 laterally. The outer ends of the first pin 7 and the second pin 8 are provided with a crossbar 9. A spring 10 is connected between the middle part of the crossbar 9 and the mounting block 2. The two ends of the crossbar 9 are sliding ends 9.1. Under the action of the spring 10, the sliding ends 9.1 rebound from the inside of the sliding plate to the outside of the sliding plate from the corresponding notch 5.

[0032] In this technical solution, the first sliding plate 3 and the second sliding plate 4 are inclined. During the extension and retraction of the telescopic rod 6, the first and second pins 7 and 8 are connected to the crossbar 9, enabling the first and second pins 7 and 8 to move forward and backward along the mounting block 2. This allows the first and second pins 7 and 8 to insert into and exit between the gaps of the stacked papers. Combined with the retraction of the telescopic rod 6, the upper stacked paper 11 is lifted, thus separating the upper stacked paper 11 from the lower stacked paper 12. Even when there are many upper stacked papers 11, separating the upper stacked paper 11 prevents it from putting pressure on the lower stacked paper 12 during discharge, thereby solving the problem of large discharge thickness error of the lower stacked paper 12 caused by the heavy pressure of the upper stacked paper 11.

[0033] To more clearly demonstrate the material distribution process, the specific steps are as follows:

[0034] like Figures 5-6 As shown, the sliding end 9.1 of the crossbar 9 is located near the outer end of the slide plate. At this time, the spring 10 is in a stretched state, and the first pin 7 and the second pin 8 are out of the paper gap. Figures 7-8As shown, during the continued extension of the telescopic rod 6, the sliding end 9.1 of the crossbar 9 separates from the sliding plate, losing the support of the sliding plate for the crossbar 9. At this time, under the action of the spring 10, the crossbar 9, the first pin 7, and the second pin 8 move rapidly towards the stacked paper direction until the first pin 7 and the second pin 8 simultaneously insert into the gap of the stacked paper; then, as... Figures 9-10 As shown, the telescopic rod 6 retracts. During this process, the first pin 7 and the second pin 8 can move the upper stacked paper 11 upwards, thereby separating the upper stacked paper 11 from the lower stacked paper 12. Simultaneously, when the crossbar 9 moves to a position above the slide plate, the crossbar 9 will continue to compress the spring 10 due to the pressure of the slide plate, and the first pin 7 and the second pin 8 will continue to extend. Figures 11-14 As shown, when the telescopic rod 6 retracts to its maximum extent, and the crossbar 9 slides to the position of the notch 5, the pressure of the spring 10 below the crossbar 9 is released, and the crossbar 9 extends slightly to the outside of the slide plate, as... Figures 15-16 As shown, the crossbar slides along the outside of the slide plate. During this process, the crossbar, the first pin, and the second pin exit the paper gap. Then, in preparation for the extension and retraction of the next telescopic bar 6, the crossbar 9 slides on the slide plate, and the extension and retraction of the first pin 7 and the second pin 8 are repeated.

[0040] To improve the service life of the steel needles and crossbar 9, both the first pin 7 and the second pin 8 are steel needles, and the crossbar 9 is a steel rod. Preferably, the steel needles and the steel rod are welded together.

[0041] Example 4:

[0042] This embodiment is an optimization based on the above embodiment 3.

[0043] To facilitate adjustment of the steel needle length, the steel needle includes a pin and a screw. The pin slides with the mounting block 2, and the screw is threaded into the internal threaded hole of the pin. The end of the screw is ground into a needle tip.
