Description

Technical Field

[0001] The utility model belongs to the field of printing presses, relates to the technology of printing press scrapers, and specifically is an angle adjusting device for a printing press scraper. Background Art

[0002] A screen printing press, also known as a silk screen printing press, is a printing device that uses a screen for printing; it transfers ink to the printing material in a manner similar to weaving.

[0003] Generally, a tool rest controlled by a system to move is arranged above the screen of a screen printing press. A rotating tool holder is arranged on the surface of the tool rest. A scraper and an ink return knife are fixed on the surface of the tool holder through a clamp type hoop; a common rotation structure between the tool rest and the tool holder is to arrange two rectangular blocks approaching each other through a screw on the surface of the tool holder. A semi-cylindrical groove is opened on the surface of each rectangular block. When the contact grooves of the two rectangular blocks form a cylinder, a round rod with the same size as the cylinder is arranged on the surface of the tool rest. When the round rod is placed in the groove on the surface of the rectangular block, when the two rectangular blocks are attached, the round rod is fixed in position with the rectangular block due to friction. When there is a gap between the rectangular blocks, the rectangular blocks can be rotated on the surface of the round rod, thereby changing the angle between the tool rest and the tool holder, and realizing the angle adjustment of the scraper and the ink return knife.

[0004] However, the above adjustment method requires the operator to have rich adjustment experience. In the above adjustment method, the angle between the rectangular block and the round rod is the angle of the scraper. When adjusting, it is mainly realized by manual torsion. When torsion is performed, the angle can only be judged according to experience and the position of the scraper, and it is difficult to quickly adjust the scraper to an appropriate angle. Moreover, the above angle adjustment method is difficult to adjust the angle to a certain accurate position. Therefore, during the adjustment process, repeated operations are required, and it is difficult to accurately control the angle of the scraper.

[0005] For this reason, the utility model proposes an angle adjusting device for a printing press scraper. Summary of the Utility Model

[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] As Figures 1-8 shown, an angle adjusting device for a printing press scraper includes a printing press tool rest 1 and a tool holder 2;

[0032] It should be noted that the tool rest 1 of the printing press is slidably arranged on the surface of the screen printing press. One side of the tool holder 2 away from the tool rest 1 of the printing press is fixedly connected to the squeegee and the ink return knife through a clamp-type hoop;

[0033] An adjusting mechanism is arranged between the tool rest 1 of the printing press and the tool holder 2. The adjusting mechanism includes:

[0034] A number of adjusting blocks 31, the adjusting blocks 31 are all fixedly connected to one side of the tool rest 1 of the printing press close to the tool holder 2. A connecting rod 32 is rotatably connected inside each adjusting block 31. One end of the connecting rod 32 away from the adjusting block 31 is rotatably connected to an adjusting rod 33;

[0035] A transfer rod is rotatably connected inside the connecting rod 32. Both ends of the transfer rod are fixedly connected to the inside of the adjusting block 31, that is, the connecting rod 32 rotates inside the adjusting block 31 with the transfer rod as the center of the circle;

[0036] A number of connecting blocks 34, two of the connecting blocks 34 are in a group. Each group of connecting blocks 34 is fixedly connected to one side of the tool holder 2 close to the tool rest 1 of the printing press. The two connecting blocks 34 in a single group are symmetrically arranged. Connecting grooves 35 are formed on the surfaces of the connecting blocks 34. The two mutually symmetric connecting grooves 35 are adapted to the adjusting rod 33;

[0037] The two connecting blocks 34 are fixedly connected by a screw;

[0038] An adjusting column 36 and an operating column 37, the adjusting column 36 and the operating column 37 are both rotatably connected to the adjusting block 31. A transmission component is arranged between the adjusting column 36 and the operating column 37. Angle values are marked on the surface of the adjusting block 31, and the operating column 37 contacts the angle values; Sprockets 38 are fixedly connected to the surfaces of the adjusting column 36 and the adjusting rod 33, and a chain 39 is drivingly connected between the sprockets 38;

[0039] By operating the operating column 37, the rotation direction of the adjusting column 36 can be changed. The operable side of the adjusting column 36 is close to the printing press frame and is not convenient to operate. Through the transmission component between the adjusting column 36 and the operating column 37, the control direction can be changed, which is convenient for operation, and the operation direction is the same as the rotation direction of the squeegee, which is more convenient to directly observe the angle between the squeegee and the screen;

[0040] In the actual application process of the angle adjustment device of the printing press blade, a regulating rod 33 and a connection groove 35 are directly clamped between an adjusting block 31 and a connection block 34. Furthermore, the angle change of the blade is directly converted into the rotation of the regulating rod 33, and the rotation of the regulating rod 33 is converted into the rotation of a regulating column 36 through a sprocket 38 and a chain 39. Only by rotating the regulating column 36 inside the adjusting block 31 can the angle change of the blade be achieved. The relative control structure is smaller and easier to operate. Again, the control direction is changed through a transmission component, so that there is no obstruction during operation and the operation is more convenient.

[0041] In some specific implementation schemes, the regulating rod 33 includes two rectangular blocks and a cylinder. The sprocket 38 is fixedly connected to the surface of the cylinder. The two rectangular frames are symmetrically arranged with respect to the midpoints of the long sides of the cylinder. The connection groove 35 includes two rectangular grooves and an arc groove. The two rectangular grooves are symmetrically arranged with respect to the arc groove. The rectangular grooves are adapted to the rectangular blocks, and the arc groove is adapted to the cylinder.

[0042] In some specific implementation schemes, the above-mentioned transmission component includes a transmission bevel gear 41 fixed to the surface of the regulating column 36. An operating bevel gear 42 is fixedly connected to one side of the operating column 37 close to the transmission bevel gear 41. The transmission bevel gear 41 meshes with the operating bevel gear 42.

[0043] In a further implementation scheme, a control block 51 is slidably connected to the surface of the adjusting block 31. The control block 51 is slidably connected to the operating column 37. A control groove 52 is formed on the surface of the adjusting block 31. The control block 51 is adapted to the control groove 52. A number of annular rods 53 are slidably connected inside the control groove 52. The annular rods 53 have elasticity. A control spring 54 is fixedly connected between the annular rods 53 and the control groove 52. A spherical column 55 is fixedly connected to one side of the control block 51 close to the annular rod 53. The surface of the annular rod 53 contacts one side of the spherical column 55 that connects the control block 51. The spherical column 55 is adapted to the control groove 52.

[0044] Both sides of the annular rod 53 perpendicular to the control groove 52 are arc-shaped. Furthermore, the spherical column 55 can slide on both sides of the annular rod 53. By pressing the control block 51, the spherical column 55 can be inserted between the annular rod 53 and the control groove 52. After pulling out the control block 51, under the action of the control spring 54, the control block 51 can only slide along the curvature of the control groove 52 on the surface of the annular rod 53, which is convenient for restricting the position of the control block 51 on the surface of the adjusting block 31 and restricting the rotation of the operating column 37.

[0045] In a further implementation scheme, a moving shaft 61 is fixedly connected to the surface of the operating column 37. A moving groove 62 is formed on the surface of the control block 51. The moving shaft 61 is adapted to the moving groove 62.

[0046] Working principle of the present utility model: Fix the scraping knife and the ink-returning knife on one side of the knife holder 2 away from the printing press knife rest 1 through a clamp-type hoop; when the angle of the knife holder 2 needs to be adjusted, pull the control block 51 in the direction away from the adjusting block 31, so that the spherical column 55 on the surface of the control block 51 slides to the side of the annular rod 53 away from the adjusting block 31. At this time, the control block 51 can slide on the surface of the annular rod 53. Rotate the operating column 37 or the control block 51 to make the operating column 37 rotate inside the adjusting block 31. The rotation of the operating column 37 drives the adjusting column 36 to rotate through a cone pulley. The rotation of the adjusting column 36 drives the adjusting rod 33 to rotate through a sprocket 38 and a chain 39, thereby driving the connecting block 34 to change its position, changing the angle between the connecting block 34 and the adjusting block 31, and changing the angle between the scraping and the screen plate.

[0047] The above embodiments are only used to illustrate the technical method of the present utility model and not to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present utility model.
