Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a guiding mechanism for printing printed materials. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressing. This allows for the mass reproduction of the original content. During the printing process, it is necessary to guide and transport the printed materials to prevent misalignment or displacement of the printed patterns.

[0003] However, existing printing guide mechanisms mainly limit and guide the printing material from both sides, without limiting the printing material on the surface. This can cause surface wrinkles and bending of the printing material during transport, thus affecting the printing quality.

[0004] To address this issue, we propose a guiding mechanism for printing printed materials. Utility Model Content

[0005] The purpose of this invention is to provide a guiding mechanism for printing printed materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A guiding mechanism for printing includes a guide platform and several vertical guide rollers rotatably mounted on the guide platform. A horizontal guide roller is also provided on the guide platform, and several guide discs are sleeved around the horizontal guide roller. A bidirectional screw is rotatably mounted inside the horizontal guide roller, and a screw seat corresponding to each guide disc is externally threaded onto the screw. One end of the screw seat extends out of a groove on the surface of the horizontal guide roller and is fixed to the guide disc. Supports are symmetrically fixed on both sides of the guide platform, and sliders are vertically slidably mounted inside the supports. A turntable for supporting the horizontal guide roller is rotatably mounted on the side of the sliders that are close to each other. A gear ring is fixed on the outer ring of one of the turntables, and a drive gear is meshed on the gear ring. A motor is connected to the shaft of the drive gear.

[0008] In a further embodiment, the vertical guide rollers are distributed at the four corners of the guide platform and are symmetrical about the two sides of the horizontal guide rollers.

[0009] In a further embodiment, the vertical guide rollers on the same side of the guide platform extend into the lower part of the guide platform and are connected to the same connecting rod. A screw block is fixed below the connecting rod, and the two screw blocks are threaded through and connected to the same bidirectional screw rod II. The screw blocks are symmetrically distributed on the bidirectional screw rod II.

[0010] In a further embodiment, end caps are mounted on both ends of the transverse guide roller by screws, and end blocks are fixed on the sidewalls of the end caps.

[0011] In a further embodiment, the side wall of the turntable is provided with a sleeve that matches the end block, and the sleeve is threaded with a bolt.

[0012] In a further embodiment, the outer ring of the guide disk is wrapped with a soft layer.

[0013] In a further embodiment, a vertical single screw is rotatably mounted inside the support, and the single screw passes through the slider and is threadedly connected to it.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention applies limiting pressure to the surface of printed materials by setting horizontal guide rollers and guide discs, guiding and transporting the printed materials. This prevents wrinkles and bends from appearing on the surface of the printed materials during transport, ensuring the flatness of the printed materials surface. Furthermore, the height of the horizontal guide rollers and guide discs can be adjusted to accommodate printed materials of different thicknesses, and the lateral spacing of the guide discs on the horizontal guide rollers can also be adjusted to accommodate printed materials of different widths, making it more flexible in use.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2 A printing guide mechanism includes a guide platform 1 and several vertical guide rollers 2 rotatably mounted on the guide platform 1. When the printed matter is placed on the guide platform 1, the vertical guide rollers 2 are positioned on both sides of the printed matter, thereby limiting the position of the printed matter. At the same time, the vertical guide rollers 2 can rotate without affecting the transmission of the printed matter. In order to prevent the surface of the printed matter from wrinkling or bending, a horizontal guide roller 3 is also provided on the guide platform 1. The horizontal guide roller 3 is positioned above the printed matter, and several guide discs 4 are sleeved on the horizontal guide roller 3. The guide discs 4 are used to press on the surface of the printed matter. In order to improve the flattening effect of the printed matter, a bidirectional screw 6 is rotatably mounted inside the horizontal guide roller 3. The external thread of the bidirectional screw 6 is screwed with a screw seat 5 corresponding to each guide disc 4. One end of the screw seat 5 extends out of a groove 31 opened on the surface of the horizontal guide roller 3 and is fixed to the guide disc 4. When the bidirectional screw 6 is rotated, the screw seat 5 can move horizontally along the bidirectional screw 6 under the action of the thread and the restriction of the groove 31, thereby adjusting the spacing between the guide discs 4.

[0025] For further details, please refer to Figure 2A bolt 61 is threaded through and screwed onto the inside of the bidirectional screw 6. The bolt 61 is located at a large opening on the surface of the horizontal guide roller 3, which facilitates operation by the user. When the bolt 61 is tightened, its end is in close contact with the inner wall of the horizontal guide roller 3, thereby preventing the bidirectional screw 6 from rotating arbitrarily and ensuring the stability of the guide plate 4.

[0026] Please see Figure 3 Considering that printing plants need to print materials of different widths, vertical guide rollers 2 are set at the four corners of the guide table 1 and are symmetrical about the two sides of the horizontal guide rollers 3. The ends of the vertical guide rollers 2 on the same side of the guide table 1 that extend into the lower part of the guide table 1 are connected to the same connecting rod 13. A screw block 14 is fixed below the connecting rod 13, and the two screw blocks 14 are threaded through and connected to the same double-direction screw 15. The screw blocks 14 are symmetrically distributed on the double-direction screw 15. The two ends of the double-direction screw 15 are rotatably connected to the bases on both sides of the guide table 1, and one end of the double-direction screw 15 protrudes from the side wall of the base of the guide table 1 for easy turning by the operator. When the double-direction screw 15 rotates, it drives the two screw blocks 14 to move closer or further away from each other. At this time, the vertical guide rollers 2 move along the straight groove on the surface of the guide table 1, thereby adjusting the distance between the vertical guide rollers 2 on both sides.

[0027] Please see Figure 2 Considering that printing plants use materials of different thicknesses, symmetrical supports 7 are fixed on both sides of the guide table 1. A slider 8 is vertically slidably installed inside the support 7, and a turntable 9 for supporting the horizontal guide roller 3 is rotatably installed on the side of the slider 8 that is close to it, so that the height of the horizontal guide roller 3 can be adjusted, allowing the guide plate 4 to press the printed materials of different thicknesses. Specifically, a vertical single screw 71 is also rotatably installed inside the support 7, and the single screw 71 passes through the slider 8 and is threaded to it. By rotating the single screw 71, the slider 8 can move vertically under the limiting action of the support 7 and the thread action of the single screw 71, which facilitates the adjustment of the height. When the single screw 71 is not rotated, the height can be locked by the thread action.

[0028] Please see Figure 4 One of the turntables 9 has a gear ring 10 fixed on its outer ring, and a drive gear 11 is meshed on the gear ring 10. The drive gear 11 is supported on the slider 8 by a bearing seat. A motor 12 is connected to the shaft of the drive gear 11, and the main body of the motor 12 is fixed to the slider 8. The motor 12 drives the drive gear 11 to rotate. The drive gear 11 meshes with the gear ring 10, thereby driving the gear ring 10 to rotate. The gear ring 10 is fixed to the turntable 9, thereby driving the turntable 9 to rotate relative to the slider 8. The turntable 9 drives the horizontal guide roller 3 to rotate, and the horizontal guide roller 3 drives the guide plate 4 to rotate.

[0029] Please see Figure 2 and Figure 4The two ends of the horizontal guide roller 3 are fitted with end caps 32 by screws. The end caps 32 can be opened, so that the two ends of the horizontal guide roller 3 are open, which facilitates the disassembly and assembly of the guide plate 4 according to the design needs, thereby increasing or decreasing the number of guide plates 4. The side wall of the end cap 32 near the inside of the horizontal guide roller 3 has a protrusion, which is not shown in the figure. The end of the bidirectional screw 6 is rotated and sleeved on the outside of the protrusion, so that the bidirectional screw 6 can rotate relative to the end cap 32. The end block 33 is fixed on the other side wall of the end cap 32. The side wall of the turntable 9 is provided with a retaining sleeve 91 that matches the end block 33. The bottom of the retaining sleeve 91 is open, so that the end block 33 can be inserted into the retaining sleeve 91 from the bottom. The retaining sleeve 91 is threaded with a bolt 92. When the bolt 92 is tightened, it can be inserted into the end block 33, so that the horizontal guide roller 3 and the turntable 9 are locked together, which facilitates synchronous rotation and makes disassembly convenient later.

[0030] Please see Figure 2 The outer ring of the guide plate 4 is covered with a soft layer 41. The soft layer 41 is made of elastic rubber material, which can not only reduce the pressure damage to the surface of the printed matter, but also reduce the slippage problem and facilitate the transmission of the printed matter.
