Description

Technical Field

[0001] The invention relates to the technical field of engraving machines, in particular to a paper feeding mechanism of an engraving machine. Background Art

[0002] In modern graphic production, logo processing and other industries, engraving machines are a commonly used equipment, and their paper feeding mechanism plays a vital role in the efficiency and quality of the entire engraving work. However, the paper feeding mechanism of traditional engraving machines has many shortcomings and is difficult to meet the increasing production needs.

[0003] In terms of paper feeding stability, the paper feeding mechanism of traditional engraving machines often lacks an effective mechanism to deal with the speed difference problem that may occur during the paper feeding process. Usually, the paper feeding action mainly relies on a single power to drive the paper feeding wheel or similar components to rotate, and the paper is transported through the friction with the paper. However, in the actual paper feeding process, due to the different paper materials and thicknesses, as well as the wear of the various components of the paper feeding mechanism, the transmission accuracy and other factors, it is easy for the paper feeding speed to not match the speed required for the actual movement of the paper. For example, when the paper feeding speed of the paper feeding wheel is fast, and the paper cannot follow the movement in time due to its own characteristics (such as thick, large surface friction, etc.), the paper will stagnate, resulting in paper jams, affecting the continuity of the engraving work; on the contrary, if the paper feeding speed is too slow, the paper may accumulate at the paper feeding wheel, which will also cause problems such as paper jams or uneven paper feeding. Moreover, when facing these speed differences, the traditional paper feeding mechanism cannot flexibly adjust the rotation state of the relevant components, making it difficult to ensure the flatness of the paper, and the smoothness of the paper feeding is greatly reduced, which seriously affects the efficiency and quality of the engraving work.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The present invention is described in further detail.

[0023] The embodiment of the present invention discloses a paper feeding mechanism of a plotter. Figure 1-Figure 2, including a plotter 18, a front support plate 13 is installed on one side of the inside of the plotter 18, and a front support plate baffle 14 for limiting the paper position is symmetrically provided on the surface of the front support plate 13. The paper material is placed on the front support plate 13 in advance, and then the front support plate baffle 14 is adjusted according to the size of the paper material to be close to both sides of the paper material and pressed tightly, so that the paper material can be quickly and accurately placed and initially fixed on the plotter 18. The front support plate 13 provides a stable placement platform for the paper, and the front support plate baffle 14 can be flexibly adjusted according to the actual size of the paper to ensure that papers of different sizes can be tightly pressed, avoiding the paper from being offset or shaking during the subsequent paper feeding process, laying the foundation for accurate paper feeding. A paper feeding mechanism is installed at the bottom of the front support plate 13.

[0024] like Figure 3-Figure 4 As shown, the paper feeding mechanism includes a paper feeding shaft 12 installed on one side of the inside of the engraving machine 18, three one-way bearings 10 are fixedly installed on the outer wall of the paper feeding shaft 12 and are evenly distributed, the outside of the one-way bearing 10 is connected to a paper feeding wheel sleeve 9, and the outside of the paper feeding wheel sleeve 9 is installed with a paper feeding wheel 7, and two bearings 8 are installed inside both ends of the paper feeding wheel 7, and the bearings 8 are rotatably connected to the outer wall of the paper feeding shaft 12, and the outer walls of the two bearings 8 are connected to paper feeding shaft spacers 6, and the outer side of the paper feeding shaft spacers 6 is fixedly provided with a stopper 5 for the displacement of the paper feeding wheel 7, and a front pressure roller 17 for assisting paper feeding is installed inside the front end of the engraving machine 18, and the friction between the paper feeding wheel 7 and the paper material is relied on to make the paper material be transported to the front pressure roller 17 one by one, and the arrangement of the one-way bearing 10 enables the rotation state of the front pressure roller 17 during the paper feeding process to be flexibly adjusted according to actual conditions, and cooperate with the paper feeding action of the paper feeding wheel 7. During normal paper feeding, the front pressure roller 17 can actively drive the paper forward. When there is a difference between the paper feeding speed and the rotation speed of the front pressure roller 17, the one-way bearing 10 can ensure that the rotation of the front pressure roller 17 will not have an adverse effect on the paper, avoiding problems such as paper stagnation or arching that affect the flatness of the paper and the smoothness of paper feeding, further ensuring the stability and efficiency of paper feeding.

[0025] In the present application, a pulley is symmetrically mounted on the outer wall of one side of the plotter 18, and a synchronous belt 16 is mounted on the outer sleeve of the two pulleys. A paper feed motor 15 is fixedly mounted on the outer wall of the plotter 18, and the output end of the paper feed motor 15 is connected to one of the pulleys in a transmission manner. The output end of one of the pulleys passes through the inner wall of the plotter 18 and is transmitted to one end of the paper feed shaft 12. A spring pin 11 is symmetrically mounted on the outer wall of one end of the paper feed shaft 12, and the spring pin 11 is matched with the pulley. The setting of the spring pin 11 can prevent the paper feed shaft 12 from falling off or rotating, and can achieve a good positioning effect. The paper feed motor 15 works and the two pulleys are linked to rotate clockwise through the synchronous belt 16, and then the paper feed shaft 12 is driven to rotate clockwise. At this time, the paper feed wheel 7 rotates and contacts the paper material, and the friction between the paper feed wheel 7 and the paper material is used to transport the paper material one by one toward the front pressure roller 17. The paper feeding motor 15, as a power source, drives the paper feeding shaft 12 and the paper feeding wheel 7 to rotate stably and efficiently through the transmission of the synchronous belt 16 and the pulley, thereby realizing continuous paper feeding of paper materials. This transmission method has high reliability and stability, can ensure that the paper is transported at a uniform speed and in a stable state, reduces problems such as lettering errors or paper jams caused by unstable paper feeding, and improves the efficiency of lettering work.

[0026] In the present application, the other end of the paper feed shaft 12 extends into the engraving machine 18 and is rotatably installed with a bearing 2, which is connected to the inner wall of the engraving machine 18 to support one end of the paper feed shaft 12, and an anti-falling retaining ring 1 is provided on the outer side of the bearing 2, and a compression spring 3 is sleeved on the inner side of the bearing 2, and a retaining ring 2 4 is fixed to the end of the compression spring 3 away from the bearing 2 for easy installation and disassembly.

[0027] In the present application, a paper feed tray 19 is detachably installed at the bottom of the front end of the engraving machine 18, and a group of slide grooves 21 are opened on the inner wall of the front end of the paper feed tray 19. A movable sliding baffle 20 is installed inside the slide groove 21. The setting of the sliding baffle 20 provides neat and standardized guarantee for the stacking of paper on the paper feed tray 19. By adjusting the position of the sliding baffle 20 according to the paper size, it can be ensured that papers of different sizes can be arranged neatly on the paper feed tray 19, which is convenient for subsequent retrieval or further processing, thereby improving the cleanliness and work efficiency of the working area.

[0028] The implementation principle of the paper feeding mechanism of a plotter in an embodiment of the present invention is as follows:

[0029] When working, turn on the engraving machine 18, first place the paper material on the front support plate 13, then adjust the front support plate baffle 14 according to the size of the paper material to be close to both sides of the paper material and press it tightly, then press the front support plate 13 to make the paper material naturally fall under the paper feeding mechanism, at this time, the paper feeding motor 15 works through the synchronous belt 16 to link the two pulleys to rotate clockwise, and then drive the paper feeding shaft 12 to rotate clockwise, at this time, the paper feeding wheel 7 rotates and contacts the paper material, relying on the friction between the paper feeding wheel 7 and the paper material to make the paper material be transported to the front pressure roller 17 one by one, when the paper feeding motor 15 rotates clockwise When the front pressure roller 17 is subjected to the counterclockwise force, the one-way bearing 10 does not rotate. At this time, the front pressure roller 17 is driven to rotate and the paper material is driven forward. When the rotation speed of the front pressure roller 17 is faster than the paper feeding speed, the front pressure roller 17 is subjected to the clockwise force and the one-way bearing 10 will rotate accordingly, thereby not causing paper support or paper arching. Subsequently, the rotation of the front pressure roller 17 can assist the paper material to be transported outward to the paper feeding tray 19 for stacking, and the sliding distance of the sliding baffle 20 in the slide groove 21 is adjusted in advance according to the size of the paper material, thereby allowing the sliding baffle 20 to limit one end of the paper material so that it can be neatly stacked on the paper feeding tray 19.
