[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, a quick-detachable printing machine scraper includes a mounting frame 1 and a scraper 2;

[0029] The mounting frame 1 and the scraper 2 are detachably fixedly connected, and a ring rod is fixedly connected to the surface of the mounting frame 1, and the ring rod can be detachably connected to the inside of the printing press by bolts;

[0030] A fixing mechanism is provided between the mounting frame 1 and the scraper 2, and the fixing mechanism includes:

[0031] A contact block 31 is slidably connected to the side of the mounting frame 1 close to the scraper 2. Two contact blocks 31 are slidably provided on the surface of the mounting frame 1. The contact blocks 31 are symmetrically arranged relative to the scraper 2 and extend along the long side of the scraper 2.

[0032] The contact block 31 is provided with a frosted layer on the side close to the scraper 2. The frosted layer is a layer in contact with the surface of the scraper 2. The surface is rough and can generate a large friction force when in contact with the surface of the scraper 2, thereby restricting the scraper 2 from moving again. Both ends of the contact block 31 are fixedly connected to an operating rack 32.

[0033] It should be noted that the operating racks 32 are all L-shaped. The operating racks 32 at both ends of the same contact block 31 have the same size. The operating racks 32 at both ends of different contact blocks 31 have different widths, and the orientations of the teeth on the surfaces of the operating racks 32 are different. When the contact blocks 31 slide relative to each other, the operating racks 32 will not contact each other.

[0034] An operating rod 33 is slidably connected to the interior of the mounting frame 1. A sliding groove 34 is formed on the surface of the operating rod 33. A plurality of rotating bearings are fixedly connected to the interior of the mounting frame 1. The inner rings of the rotating bearings are each clamped with an operating gear 35, which meshes with the operating rack 32. A sliding column 36 is fixedly connected to the interior of the operating gear 35 on one side, and the sliding column 36 is adapted to the sliding groove 34.

[0035] It should be noted that the surfaces of the operating gears 35 are fixedly connected to synchronous wheels (not shown in the figure), and a synchronous belt (not shown in the figure) is connected between the synchronous wheels, that is, the rotation of the operating gear 35 on one side can drive the operating gear 35 on the other side to rotate synchronously;

[0036] A horizontal block 37 is slidably connected to the interior of the mounting frame 1. The horizontal block 37 is detachably connected to the scraper 2. Two horizontal blocks 37 are slidably provided inside the mounting frame 1. The horizontal blocks 37 are symmetrically arranged inside the mounting frame 1 relative to the center position of the length of the scraper 2.

[0037] A vertical slot 38 is provided inside the mounting frame 1 , and a horizontal spring 39 is fixedly connected between the vertical slot 38 and the horizontal block 37 . Obviously, the horizontal block 37 is adapted to the vertical slot 38 ;

[0038] The surface of the horizontal block 37 is rotatably connected to a horizontal rod 310, the middle of the horizontal rod 310 is fixedly connected to a reference rod, and a reference groove is opened on the surface of the mounting frame 1, and the reference groove is adapted to the reference rod;

[0039] It should be noted that a horizontal reference line (not shown) is marked on the surface of the mounting frame 1. By referring to the angle between the reference line and the horizontal rod 310, it is possible to quickly determine whether the horizontal rod 310 is horizontal, and thus determine the horizontal state of the scraper 2.

[0040] The scraper 2 is fixed to the mounting bracket 1 by the friction between the contact block 31 and the scraper 2, and the contact block 31 and the scraper 2 are fitted to limit the sliding position of the scraper 2, and the sliding of the contact block 31 is mainly driven by the operating rack 32 fixed on the surface, that is, by simply rotating the operating lever 33, the operating lever 33 drives the operating gear 35 to rotate, so that the contact block 31 on the surface of the mounting bracket 1 can slide toward the surface of the scraper 2, so that the position of the scraper 2 and the mounting bracket 1 is fixed. During the whole process of fixing the scraper 2, the position of the scraper 2 can be fixed by simply rotating the operating lever 33, the operation steps are reduced, and the time required for fixing is relatively reduced, which can further improve the work efficiency. A horizontal rod 310 is provided inside the mounting bracket 1, wherein the horizontal block 37 rotatably connected to the horizontal rod 310 is detachably connected to the scraper 2. The horizontal state of the scraper 2 can be directly judged by the horizontal state of the horizontal rod 310, which is more intuitive.

[0041] In some specific embodiments, a limiting slot 41 is provided inside the mounting frame 1, and one end of the operating rod 33 close to the horizontal block 37 is fixedly connected to the limiting block 42;

[0042] It should be noted that the limit block 42 is rectangular, and the bottom of the limit groove 41 is in the shape of a rectangular array, that is, the limit block 42 can be clamped to the bottom of the limit groove 41 at any angle; after the limit block 42 is clamped with the bottom of the limit groove 41, the limit block 42 cannot rotate, that is, the operating rod 33 cannot continue to rotate. At this time, the sliding groove 34 on the surface of the operating rod 33 and the sliding column 36 inside the operating gear 35 are adapted to each other, so that the operating gear 35 cannot rotate; that is, after the limit block 42 is clamped with the limit groove 41, the operating rod 33 and the operating gear 35 cannot rotate;

[0043] The surface of the mounting frame 1 away from the fixed position of the printing press is provided with a moving groove 43, a moving block 44 is slidably connected inside the moving groove 43, and a moving spring 45 is fixedly connected between the moving groove 43 and the moving block 44;

[0044] It should be noted that when the moving spring 45 is in the natural state, the surface of the moving block 44 contacts the end of the operating rod 33 without the limit block 42, thereby limiting the movement of the operating rod 33;

[0045] In a further embodiment, a fixing groove 51 is provided on the surface of the horizontal block 37, a pressing block 52 is slidably connected to the interior of the horizontal block 37, a plurality of fixing rods 53 are fixedly connected to the interior of the pressing block 52, a plurality of fixing shafts are fixedly connected to the interior of the horizontal block 37, and a fixing block 54 is rotatably connected to the surface of the fixing rods 53 and the fixed shafts;

[0046] It should be noted that the fixed rod 53 and the fixed shaft are symmetrically arranged relative to the center position of the pressing block 52, and their extension direction is parallel to the extension direction of the horizontal rod 310. The fixed block 54 is provided with an elastic layer on the side close to the scraper 2. The elastic layer is elastic and relatively rough. When the elastic layer contacts the surface of the scraper 2, it is squeezed and can limit the position of the scraper 2 through friction.

[0047] A fixing spring 55 is fixedly connected between the pressing block 52 and the fixing slot 51;

[0048] The pressing block 52 is provided with a gradient groove 61 on the side away from the scraper 2;

[0049] It should be noted that the gradient groove 61 is in the shape of a heart as a whole, with the depths at both end points being the same, and the depths on the left and right sides of the end points increasing or decreasing;

[0050] The interior of the movable groove 43 is fixedly connected to a pressing rod 62, and the surface of the pressing rod 62 is rotatably connected to a movable rod 63. The movable rod 63 is provided with a cylindrical shaft at one end away from the pressing rod 62, and the cylindrical shaft is adapted to the gradient groove 61;

[0051] The working principle of the present invention is as follows: the scraper 2 is placed on the surface of the mounting frame 1 at the position corresponding to the pressing block 52, and the scraper 2 is pressed toward the inside of the mounting frame 1. The pressing block 52 will slide toward the inside of the horizontal block 37 under the action of the scraper 2. The sliding of the pressing block 52 causes the fixed block 54 to rotate. The fixed block 54 rotates until it contacts the surface of the scraper 2. At this time, the angle of the horizontal rod 310 is observed. If the horizontal rod 310 is horizontal, the contact block 31 can be operated to slide toward the surface of the scraper 2. If the horizontal rod 310 is not horizontal, the corresponding side of the scraper 2 is pressed. Move the pressing block 52 upward and reposition that side; when adjusting the position of the contact block 31, first slide the moving block 44 to disengage the surface of the moving block 44 from the surface of the operating rod 33, slide the operating rod 33 to disengage the limit block 42 from the limit groove 41, and then rotate the operating rod 33. At this time, the operating gear 35 rotates, driving the operating rack 32 to slide, causing the contact block 31 to move toward each other. After the surface of the contact block 31 contacts the surface of the scraper 2, the position of the scraper 2 is limited by friction. After the scraper 2 is limited, the position of the operating rod 33 can be restored.

[0052] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
