Description

Technical Field

[0001] The utility model relates to a pressing plate mechanism. Background Art

[0002] Pencils, as learning supplies, play a vital role in our lives. With the continuous development of society, pencil manufacturing processes are also constantly improving. A pencil grooving machine, for example, is a device that grooves the lead core in pencil sheets. Existing pencil grooving machines use rubber rollers to drive the pencils on a conveyor belt, feeding them into a grooving blade for conveying and grooving. However, due to the fixed height of the conventional pressing plate during conveying, some thicker pencils, while still within tolerance, cannot be smoothly conveyed and subsequently processed.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figures 1 to 5 As shown, a pressing plate mechanism provided in this embodiment includes the pressing plate mechanism 900, the pressing plate mechanism 900 includes a pressing plate beam front seat 902, the pressing plate beam front seat 902 is mounted on a positioning plate 901, the positioning plate 901 is assembled on a frame, the rear of the pressing plate beam front seat 902 is provided with a pressing plate beam tail seat 904 arranged parallel to it, the pressing plate beam front seat 902 and the pressing plate beam tail seat 904 are commonly connected with a pressing plate beam 905 that can be flipped down and pressed, and the pressing plate beam 905 is symmetrically provided with at least two. In order to better achieve the effect of pressing down, see details. Figure 1 and2 On one side facing the center of the pressing plate crossbeam 905, there is a cutter shaft pressing plate 906. The cutter shaft pressing plate 906 is locked at the bottom end of the pressing plate crossbeam 905. The cutter shaft pressing plate 906 is provided with a "冂"-shaped upward opening matching the bottom of the pressing plate crossbeam 905. The side of the cutter shaft pressing plate 906 facing the center is inclined, and the pressing bottom surface of the cutter shaft pressing plate 906 is horizontally arranged. The distance between the two cutter shaft pressing plates 906 is not greater than the length of the conveyed sheet. In this way, when the sheet is conveyed between the two cutter shaft pressing plates 906, it can be effectively pressed by the cutter shaft pressing plates 906 on both sides, facilitating the cutting of the surface layer of the sheet by the upper blade;

[0029] An elastic downward pressing member is assembled on each pressing plate crossbeam 905. Specifically, the elastic downward pressing member includes a pressing plate crossbeam swing rod 907 fixedly connected above the pressing plate crossbeam 905. The two pressing plate crossbeam swing rods 907 are交错套接 (interleaved and sleeved) on the pressing plate crossbeam front seat 902. The other end of the pressing plate crossbeam swing rod 907 is movably connected to a pressing plate crossbeam movable pin 908. The pressing plate crossbeam movable pin 908 vertically penetrates into the pressing plate crossbeam front seat 902 and moves up and down along it. The lower half of the pressing plate crossbeam movable pin 908 has an external thread. During assembly, a first compression spring 909 is sleeved on the pressing plate crossbeam movable pin 908 from bottom to top and is limited by a first butterfly nut 910 screwed on from bottom to top. The other side of the first compression spring 909 abuts against the lower part of the pressing plate crossbeam front seat 902. As shown in the figure, in order to improve the utilization effect of space, the middle section of the pressing plate crossbeam swing rod 907 is provided with a circular arc transition;

[0030] In order to achieve the ability of the pressure plate crossbeam 905 to flip and move downward in conjunction with the elastic pressing member, we have made special restrictions on the position of the axis of the pressure plate crossbeam 905: the left and right sides of the pressure plate crossbeam front seat 902 are pressed into the pressure plate crossbeam adjustment block 903 and locked by bolts, the front end axis of the pressure plate crossbeam 905 is sleeved on the mounting hole of the beam adjustment block 903, the rear end axis of the pressure plate crossbeam 905 is sleeved in the movable groove of the pressure plate crossbeam tail seat 904, and a pressure plate adjustment column 911 is provided on the top of the movable groove, and the rear end axis of the pressure plate crossbeam 905 is abutted against the bottom of the pressure plate adjustment column 911, and the bottom of the pressure plate adjustment column 911 is pressed by the pressure plate The spring positioning column 912 is against the top, and the bottom of the pressure plate spring positioning column 912 is sleeved in the second compression spring 913, and the other side of the second compression spring 913 is limited on the frame. The pressure plate adjustment column 911 is always in contact with the limiting groove on the inner side of the pressure plate beam tail stock 904 during the movement. The limiting groove is vertically set in the pressure plate beam tail stock 904. This setting allows the pressure plate beam 905 to move slightly downward under the pull of the elastic lower pressure piece, thereby ensuring that the knife shaft pressure plate 906 is well pressed on the plate. In order to achieve effective support of the rear end axis, the pressure plate spring positioning column 912 is set in a "Y" shape or has an arc notch on the top.

[0031] Working principle: Figure 1 and 5 This solution is set on the second and third positions of the three-axis slotting machine, and is mainly used to press the plate from top to bottom, controlling the plate within a certain deviation range to be able to pass through the pressing plate mechanism and be planed out of the upper slot by the upper blade. The specific adjustment and adaptation method is: by adjusting the degree of tightening the first butterfly nut on the movable pin of the pressure plate crossbeam upward or downward, the tension of the first compression spring is adjusted. When the first butterfly nut is adjusted upward, the tension of the first compression spring becomes tighter, thereby causing the elastic downward pressure member (specifically, the relevant connection part of the pressure plate crossbeam rocker in the figure) to swing downward. The amplitude becomes smaller, and at this time, the controllable range of the plate that the knife shaft pressure plate enters is smaller, that is, the elastic buffer zone is smaller; when the first butterfly nut is adjusted downward, the tension of the first compression spring becomes loose, thereby making the elastic downward pressure member (specifically, the pressure plate crossbeam rocker-related connection part in the figure) move downward more, and the controllable range of the plate that can enter the knife shaft pressure plate is larger, that is, the elastic buffer zone is larger; at the same time, the rear end axis of the corresponding matching pressure plate crossbeam is also driven by the elastic downward pressure member, and the rear end axis of the pressure plate crossbeam is driven to tighten and press down in the movable groove, thereby ultimately making the knife shaft pressure plate and the plate better fit.
