Technical Field

[0001] The utility model relates to the technical field of printed products, in particular to a device for accurately positioning printed products. Background Art

[0002] Printed materials, such as printed books, newspapers, pictures, etc., are various printed products. It is a general term for various finished products produced using printing technology. In daily life, people come into contact with newspapers, books, magazines, maps, posters, advertisements, envelopes, letterheads, file bags, trademarks, labels, business cards, invitations, banknotes, greeting cards, desk calendars, wall calendars, picture albums, various certificates, packaging boxes, gift boxes, circuit boards, etc., all of which belong to the category of printed materials. Printed materials are almost everywhere in people’s clothing, food, housing, and transportation, and they are closely related to people’s lives.

[0003] When printing, most of the printing materials are conveyed for batch printing. Therefore, they are easily affected by the conveying, resulting in uneven surface of the printed product, and printing errors due to wrinkles in the printed parts. It is not convenient to flatten the printed parts during printing. Therefore, we propose a precise positioning device for printed products. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a printed product precision positioning device, including a base 1, a bracket 2 is fixedly connected to the top of the base 1, a moving plate 21 is arranged inside the bracket 2, an electric cylinder is fixedly connected to the top of the bracket 2, the output end of the electric cylinder is fixedly connected to the top of the moving plate 21, and the front and rear sides of the inner wall of the bracket 2 are provided with slide grooves, and the inner walls of the two slide grooves are respectively slidably connected to the front and rear sides of the moving plate 21 through sliders, and a printing device 22 is arranged below the moving plate 21, and a groove is opened below the moving plate 21, and a screw rod is arranged inside the groove, and a moving block is threadedly connected to the rod wall of the screw rod, and the bottom of the moving block is fixedly connected to the top of the printing device 22, and the inside of the bracket 2 includes:

[0028] The flattening assembly 3 includes a pressing roller 31 and a cooling roller 32. The cooling roller 32 is arranged on the right side of the pressing roller 31. The surfaces of the pressing roller 31 and the cooling roller 32 are both fixedly connected with an anti-sticking ink sleeve 33. The material of the anti-sticking ink sleeve 33 is a silicone material.

[0029] A plurality of first grooves are provided on the bottom of the movable plate 21. The plurality of first grooves are respectively provided on the left and right sides of the front and rear surfaces of the bottom of the movable plate 21. The interiors of the plurality of first grooves include:

[0030] The connecting component 4 includes a connecting rod 41, a connecting piece 42 is fixedly connected to one side of the connecting rod 41, a return spring 43 is fixedly connected to the surface of the connecting piece 42, a mounting ring 44 is fixedly connected to the upper end of the return spring 43, a mounting shaft 45 is provided on the inner wall of the mounting ring 44, and the mounting shaft 45 is provided on one side of the mounting ring 44.

[0031] The upper end of the connecting rod 41 is rotatably connected to the front and rear sides of the inner wall of the first groove through the first rotating shaft, and the front and rear ends of the mounting shaft 45 are fixedly connected to the front and rear sides of the inner wall of the first groove respectively.

[0032] The inner wall of the pressure roller 31 is rotatably connected to a mounting rod 34 , the inner wall of the cooling roller 32 is rotatably connected to a connecting tube 35 , and the front and rear ends of the mounting rod 34 and the front and rear ends of the connecting tube 35 are fixedly connected to the lower end of the connecting rod 41 respectively.

[0033] A plurality of air inlet holes 351 are formed on the wall of the connecting pipe 35 , and a plurality of air outlet holes 321 are formed on the front of the cooling roller 32 .

[0034] Sealing rings 36 are provided on both the front and rear surfaces of the cooling roller 32 , and the inner walls of the two sealing rings 36 are fixedly connected to the front and rear sides of the pipe wall of the connecting pipe 35 , respectively.

[0035] During use, the material to be printed is placed on the base 1, and the movable plate 21 is driven to move by the electric cylinder so that the printing device 22 on the movable plate 21 can be close to the material for printing. When the movable plate 21 moves, the pressure roller 31 and the cooling roller 32 under the movable plate 21 are close to the top of the material on the base 1. When the movable plate 21 continues to move downward, the pressure roller 31 and the cooling roller 32 are subjected to the pressure of the movable plate 21 moving downward. At this time, the pressure roller 31 and the cooling roller 32 move to both sides on the base 1, and the pressure roller 31 and the cooling roller 32 flatten the material on the base 1 to both sides, so that the printing position of the printing device 22 can be kept flat when printing. The pressure roller 31 and the cooling roller 32 rotate on the mounting rod 34 and the connecting pipe 35 respectively, and the anti-sticking ink sleeve 33 on the pressure roller 31 and the cooling roller 32 prevents the ink on the material from sticking.

[0036] When the pressure roller 31 and the cooling roller 32 move, the mounting rod 34 and the connecting tube 35 rotate in the first groove through the connecting rod 41. When the connecting rod 41 rotates, the return spring 43 is connected to the connecting rod 41 through the connecting piece 42. The connecting piece 42 is connected to the mounting shaft 45 and the first groove through the mounting ring 44. Therefore, when the connecting rod 41 rotates, the return spring 43 is compressed, so that the pressure roller 31 and the cooling roller 32 can move to both sides of the movable plate 21 to unfold the material.

[0037] Example 2

[0038] Reference Figure 1-4 , which is the second embodiment of the utility model, a heat dissipation fan 5 is fixedly connected to the right side of the movable plate 21, and the heat dissipation fan 5 is arranged on the rear side of the movable plate 21. An air intake hose 51 is fixedly connected to the right side of the heat dissipation fan 5, and the lower end of the air intake hose 51 is fixedly connected to the rear end of the connecting pipe 35, and the lower end of the air intake hose 51 passes through the rear end of the connecting pipe 35 to the inside thereof.

[0039] During use, when printing is in progress, the printed product moves to the right, at which time the heat dissipation fan 5 is started, so that the heat dissipation fan 5 delivers cold air to the connecting pipe 35 through the air intake hose 51, and the cold air enters the cooling roller 32 through the air intake hole 351 on the connecting pipe 35, so that the temperature of the surface of the cooling roller 32 drops. Therefore, after the cooling roller 32 contacts the top of the product, since the temperature of the cooling roller 32 is relatively low, the ink that has just been printed is cooled, so that the ink can be quickly cooled and fixed, and the cold air in the cooling roller 32 is discharged through the exhaust hole 321.

[0040] The remaining structures are the same as those of Example 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
