[0002] Printing presses are divided into letterpress, lithography, gravure and screen printing presses; according to paper and printing method, they are divided into single-sheet and web printing presses and flatbed, rotary flatbed and rotary rotary printing presses. A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and installed on a printing press. Then, ink is applied to the places with text and images on the printing plate by hand or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating a printed product identical to the printing plate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 As shown, a paper guide structure of a printing press includes a chassis 1, a bracket 36 is provided at the top of the chassis 1; a guide structure is provided on one side of the chassis 1;

[0026] The guide structure includes a platform 31, two sets of mounting plates 32 are welded on the top of the platform 31, motors 33 are mounted on the tops of the two sets of mounting plates 32, the output end of the motor 33 is welded to one side of a rotating rod 34, a side of the rotating rod 34 away from the motor 33 is rotatably connected to a roller 35, and a mounting block 44 is provided on the side of the chassis 1 away from the platform 31;

[0027] During operation, the motor 33 on one side of the engine box 1 drives the rotating rod 34 on its output end to rotate at the same time. When the rotating rod 34 starts to rotate, the roller 35 connected to one side of it rotates accordingly. Setting the motor 33 at the top of the mounting plate 32 ensures that the position of the motor 33 during operation is consistent, and setting the mounting plate 32 at the top of the platform 31 further ensures the fixity of the mounting plate 32.

[0028] Furthermore, both ends of the roller 35 are sleeved inside the bracket 36, the outer side of the roller 35 is rotatably connected to the conveyor belt 37, and a first connecting plate 38 is welded to one side of the bracket 36;

[0029] During operation, when the roller 35 starts to rotate, the conveyor belt 37 moves with the rotation of the roller 35. When the conveyor belt 37 starts to move, the printing material is placed on the surface of the conveyor belt 37, and the printing material is then transported to the inside of the printing machine, pushing the bracket 36 so that it drives the roller 35 and the conveyor belt 37 arranged inside it to move simultaneously. When the bracket 36 moves to the top of the chassis 1, the bracket 36 is pressed downward, and the belt moves simultaneously with the first connecting plate 38 connected to one side.

[0030] Furthermore, the bottom end of the first connecting plate 38 is welded to the top end of the extension plate 39, and a first abutting block 40 is provided at one end of the extension plate 39 away from the first connecting plate 38. A second abutting block 41 is provided inside one side of the mounting block 44, and the second abutting block 41 is welded to one end of the pull rod 43. A spring 42 is welded to one side of the second abutting block 41, and one end of the spring 42 away from the second abutting block 41 is welded to an inner wall of one side of the mounting block 44.

[0031] During operation, the first connecting plate 38 moves while driving the extension plate 39 connected to the bottom end to move accordingly. When it moves to a certain distance, that is, when the first abutment block 40 provided at the bottom end of the extension plate 39 is located inside the mounting block 44 provided on one side of the chassis 1, the first abutment block 40 is pressed downward against the second abutment block 41 by pressure. When the first abutment block 40 forms a force on the second abutment block 41, the second abutment block 41 retracts to one side of the mounting block 44. At this time, the second abutment block 41 forms a force on the spring 42. When the first abutment block 40 completely passes the second abutment block 41, the second abutment block 41 is subjected to the reaction force of the spring 42. It rebounds and forms an abutment with the first abutment block 40. At this time, the bracket 36 is fixed on the top of the chassis 1. When the bracket 36 needs to be removed from the top of the chassis 1, the pull rod 43 is pulled to drive the spring 42 to move at the same time. When the spring 42 is retracted to one side of the mounting block 44 by the force of the pull rod 43, the spring 42 drives the second abutment block 41 connected to the other end to move at the same time. When the abutment between the second abutment block 41 and the first abutment block 40 disappears, the bracket 36 can be pulled to leave the interior of the mounting block 44 with the first connecting plate 38 and the extension plate 39 connected to one side. At this time, the connection between the bracket 36 and the chassis 1 can be cancelled.

[0032] Furthermore, a bottom rod 45 is provided at the top of the bracket 36, a working box 46 is welded to the top of the bottom rod 45, a rotating block 48 is provided on one side of the working box 46, and the rotating block 48 is welded to one end of the screw rod 47;

[0033] During operation, the working box 46 is set on the top of the bracket 36 through the bottom rod 45, thereby reducing the space occupied by the set mechanism on the surface of the chassis 1, and the establishment of the bottom rod 45 also realizes the fixing function of the working box 46. When it is necessary to print printing materials of different materials, the rotating block 48 is rotated, and the screw rod 47 connected to one side moves simultaneously with the movement of the rotating block 48.

[0034] Furthermore, the screw rod 47 is rotatably connected to one side of the push block 49. There are two groups of push blocks 49. The bottom ends of the two groups of push blocks 49 are both provided with a second connecting plate 50. The bottom ends of the second connecting plates 50 are welded with an adjusting plate 51.

[0035] During operation, when the screw rod 47 starts to rotate, it drives the push block 49 which is rotatably connected at one end to move simultaneously, and the bottom end of the push block 49 is connected to the second connecting plate 50, and the bottom end of the second connecting plate 50 is connected to the top of the adjusting plate 51, that is, the rotating block 48 is rotated, so that the two sets of adjusting plates 51 are driven to move simultaneously.

[0036] Furthermore, a first rack 52 is welded to one side of the push block 49, the first rack 52 is meshed with one side of the transmission gear 53, the transmission gear 53 is rotatably connected to the top of the fixed rod 54, the fixed rod 54 is welded to the inside of the working box 46, and a second rack 55 is meshed to the side of the transmission gear 53 away from the first rack 52, the second rack 55 is welded to one end of another set of push blocks 49, a slider 56 is welded to the top of the other set of push blocks 49, and the slider 56 is slidably connected to the inside of the working box 46;

[0037] During operation, when the push block 49 starts to move, the first rack 52 connected to one end thereof rotates at the same time, and a transmission gear 53 is meshed on one side of the first rack 52. When the first rack 52 rotates, it drives the transmission gear 53 to rotate at the same time. When the transmission gear 53 starts to rotate, the second rack 55 meshed on the other side thereof rotates accordingly, and the second rack 55 is connected to one side of another group of push blocks 49, that is, the rotating block 48 is rotated, driving the adjustment plate 51 to move at the same time, and a slider 56 is fixedly connected to the top end of the other group of push blocks 49. When the push block 49 starts to move, the slider 56 is slidably connected to the inside of the working box 46, and the function of adjusting printing materials of different specifications is realized at this time.

[0038] Working principle: When it is necessary to guide the printing material of the printing press, push the bracket 36 to drive the roller 35 and the conveyor belt 37 set inside it to move simultaneously. When the bracket 36 moves to the top of the chassis 1, press the bracket 36 downward to move the first connecting plate 38 connected to one side at the same time. When the first connecting plate 38 moves, it drives the extension plate 39 connected to the bottom to move with it. When it moves to a certain distance, the first abutment block 40 set at the bottom of the extension plate 39 is located in the chassis. 1, the first abutting block 40 is pressed downward against the second abutting block 41 by the pressure. When the first abutting block 40 exerts a force on the second abutting block 41, the second abutting block 41 retracts toward one side of the mounting block 44. At this time, the second abutting block 41 exerts a force on the spring 42. When the first abutting block 40 completely passes through the second abutting block 41, the second abutting block 41 rebounds under the reaction force of the spring 42 and abuts against the first abutting block 40. At this time, the bracket 36 is fixed to the chassis 1. When the bracket 36 needs to be removed from the top of the chassis 1, the pull rod 43 is pulled to drive the spring 42 to move at the same time. When the spring 42 is retracted to one side of the mounting block 44 by the force of the pull rod 43, the spring 42 drives the second abutting block 41 connected to the other end to move at the same time. When the abutment between the second abutting block 41 and the first abutting block 40 disappears, the bracket 36 can be pulled to leave the interior of the mounting block 44 with the first connecting plate 38 and the extension plate 39 connected to one side. At this time, the bracket 36 can be removed. The frame 36 is connected to the chassis 1. At this time, the motor 33 on one side of the engine box 1 drives the rotating rod 34 at its output end to rotate at the same time. When the rotating rod 34 starts to rotate, the roller 35 connected to one side thereof rotates accordingly, and the roller 35 is sleeved inside the conveyor belt 37. When the roller 35 starts to rotate, the conveyor belt 37 moves with the rotation of the roller 35. When the conveyor belt 37 starts to move, the printing material is placed on the surface of the conveyor belt 37, and the printing material is driven to be transported to the inside of the printing machine.

[0039] When the printing press is conveying and printing printing materials of different materials, the rotating block 48 is rotated to drive the screw rod 47 connected to one end to rotate at the same time. When the screw rod 47 starts to rotate, it drives the push block 49 connected to one end to move at the same time. The bottom end of the push block 49 is connected to the second connecting plate 50, and the bottom end of the second connecting plate 50 is connected to the top of the adjusting plate 51. When the push block 49 starts to move, the first rack 52 connected to one end thereof rotates at the same time, and one side of the first rack 52 is meshed with a transmission gear 53. The first rack 52 is meshed with a transmission gear 53. When the bar 52 rotates, it drives the transmission gear 53 to rotate at the same time. When the transmission gear 53 starts to rotate, the second rack 55 meshing on the other side of it rotates accordingly, and the second rack 55 is connected to one side of another group of push blocks 49, that is, the rotating block 48 is rotated, driving the adjustment plate 51 to move at the same time, and the top of the other group of push blocks 49 is fixedly connected with a slider 56. When the push block 49 starts to move, the slider 56 is slidably connected to the inside of the working box 46, at this time, the function of adjusting printing materials of different specifications is realized.
