Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an adjustable paper pressing rod. Background Art

[0002] Traditional engraving machines are mostly used in the industrial field, and they use cutting equipment to complete the fine cutting of materials such as advertising materials, quick printing of pictures and texts, and office labels. However, with the development of DIY culture and changes in market demand, miniaturized and household engraving equipment has become increasingly popular. In order to achieve simplicity and ease of use in design, these small engraving machines usually adopt an integrated paper pressing structure, that is, the pressure adjustment of the paper pressing rod can only be achieved through overall adjustment. Although this integrated adjustment method is convenient for design and manufacturing, it has obvious limitations in actual use.

[0003] During the engraving process, different thicknesses and materials of paper or stickers require different pressures. However, the existing paper-pressing mechanisms of small engraving plotters cannot independently adjust each paper-pressing lever, making it difficult to ensure precise pressure adaptation when processing different materials. This limitation can lead to unsatisfactory paper-pressing effects, such as paper slippage, misalignment, or uneven indentation, which in turn affects cutting quality and results.

[0004] Therefore, an adjustable paper pressing rod is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide an adjustable paper pressing rod, which aims to solve the problem that the existing integrated adjustment method of the paper pressing structure is difficult to ensure accurate adaptation of the pressure when dealing with different materials, thereby affecting the cutting quality.

[0010] an elastic component, located between the adjusting component and the paper pressing rod, and configured to apply elastic force to the tail end of the paper pressing rod so that the head end of the paper pressing rod applies downward pressure to the workpiece;

[0011] The adjusting component is used to adjust the elastic force applied by the elastic component to the paper pressing rod by sliding on the paper pressing rod seat.

[0012] Furthermore, the elastic component includes an elastic seat and a spring, one end of the spring is connected to the elastic seat, and the other end of the spring is connected to the paper pressing rod.

[0013] Furthermore, the adjustment assembly includes an adjusting bolt and an adjusting nut, one end of the adjusting bolt is connected to the elastic seat, and the other end of the adjusting bolt penetrates the paper pressing rod seat and extends to the outside, and is threadedly connected to the adjusting nut, for adjusting the relative position with the elastic seat through the adjusting nut.

[0040] Reference Figure 1 , the utility model discloses an adjustable paper pressing rod, a paper pressing rod seat 700;

[0041] The paper pressing rod 100 is hinged to the paper pressing rod base 700;

[0042] An adjustment assembly is slidably mounted on the paper pressing rod seat 700 and is located at the rear end of the paper pressing rod 100;

[0043] An elastic component is located between the adjustment component and the paper pressing rod 100, and is used to apply elastic force to the tail end of the paper pressing rod 100 so that the head end of the paper pressing rod 100 applies downward pressure to the workpiece;

[0044] The adjusting component is used to adjust the elastic force applied by the elastic component to the paper pressing rod 100 by sliding on the paper pressing rod seat 700;

[0045] The elastic component includes an elastic seat 200 and a spring 300, one end of the spring 300 is connected to the elastic seat 200, and the other end of the spring 300 is connected to the paper pressing rod 100;

[0046] The adjustment assembly includes an adjustment bolt 400 and an adjustment nut 500. One end of the adjustment bolt 400 is connected to the elastic seat 200. The other end of the adjustment bolt 400 penetrates the paper pressing rod seat 700 and extends to the outside and is screwed to the adjustment nut 500. The relative position of the adjustment bolt 400 with the elastic seat 200 is adjusted by the adjustment nut 500.

[0047] A paper pressing wheel 600 is provided on the side of the paper pressing rod 100 away from the adjusting assembly, and the paper pressing wheel 600 is rotatably connected to the paper pressing rod 100;

[0048] The springs 300 are provided in two groups, and the two groups of springs 300 are symmetrically distributed on both sides of the adjusting bolt 400.

[0049] The present embodiment provides a paper pressing rod structure with an adjustable pressure function. Conventional paper pressing devices can often only adjust the pressure as a whole, resulting in an inability to achieve fine adjustment when processing different workpieces or materials. In this embodiment, the adjustment assembly includes an adjusting bolt 400 and an adjusting nut 500. When the adjusting nut 500 is loosened, the elastic seat 200 moves upward, thereby compressing the upward stress of the spring 300, increasing the downward force of the paper pressing rod 100, and ultimately increasing the force of the paper pressing roller 600. Conversely, the adjusting nut 500 tightens the spring 300 and presses the downward stress of the spring 300, thereby reducing the upward force of the paper pressing rod 100 and ultimately reducing the force of the paper pressing roller 600. Through this design, the pressure of the paper pressing rod 100 can be independently adjusted, thereby better adapting to paper or workpieces of different thicknesses and materials. Combined with the elastic effect of the spring 300, precise control of the position of the paper pressing rod 100 is achieved, thereby controllably adjusting the paper pressing force. The paper pressing rod 100 can be adjusted by rotating the adjustment assembly clockwise or counterclockwise to complete the up and down movement of the paper pressing roller 600. This design allows the user to precisely control the pressure of the paper pressing rod 100 according to different usage requirements and paper characteristics. Precise pressure control can ensure the stability of the paper during printing or copying, reduce printing errors caused by paper sliding or misalignment, and thus improve the quality of printing or copying.

[0050] The paper pressing rod seat 700 is provided with a mounting groove 710 for mounting the paper pressing rod 100, and the paper pressing rod 100 is rotatably connected to the inner wall of the mounting groove 710;

[0051] A roller shaft 900 is provided in the width direction of the paper pressing rod 100 , and the paper pressing rod seat 700 is rotatably connected to the paper pressing rod 100 via the roller shaft 900 .

[0052] The paper pressing rod seat 700 is designed in an inverted concave shape. The paper pressing rod seat 700 is covered on the paper pressing rod 100. The paper pressing rod 100 and the paper pressing rod seat 700 are rotatably connected through the roller 900. This design can not only effectively fix the paper pressing rod 100, but also enable the paper pressing rod 100 to move up and down smoothly within a fixed path. This design utilizes a structure that combines rotation and sliding, which can reduce friction and vibration of the paper pressing rod 100 when it moves up and down, and further improve the smoothness and accuracy of the adjustment process.

[0053] The rod seat is provided with a plurality of positioning posts 720 for installation and fixation of the spreader.

[0054] By arranging the positioning column 720 on the rod base, the paper pressing rod 100 and the sheeting machine can be quickly and accurately installed and fixed.

[0055] The inner wall of the paper pressing rod seat 700 is provided with a limiting groove 800 , and the elastic seat 200 is provided with a clamping block 210 , and the clamping block 210 is connected to the limiting groove 800 .

[0056] In this embodiment, a limiting groove 800 is provided on the inner wall of the paper pressing rod seat 700 near the spring 300, wherein clamping blocks 210 that cooperate with the limiting groove 800 are provided on both sides of the length direction of the elastic seat 200. When the adjusting nut 500 is loosened, the elastic seat 200 moves along the opening trajectory of the limiting groove 800, thereby compressing the upward stress of the spring 300 to increase the downward force of the paper pressing rod 100 and ultimately increase the force of the paper pressing wheel 600. The design of the limiting groove 800 and the clamping block 210 enables the elastic seat 200 to move stably upward along the paper pressing rod seat 700, preventing the elastic seat 200 from offsetting relative to the paper pressing rod seat 700 during the movement.

[0057] A positioning block is provided on one side of the elastic seat 200 and the paper pressing rod seat 700 opposite to each other, for fixing the spring 300 .

[0058] A positioning block for fixing the spring is provided on one side of the elastic seat 200 and the paper pressing rod seat 700 opposite to each other. This design makes it easier to disassemble and install the spring 300 when it needs to be replaced.
