Description

Technical Field

[0001] This utility model relates to the technical field of printing presses, specifically a newspaper conveying device for printing presses. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, impression, and paper feeding (including folding). Its working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images, and the image is then transferred directly or indirectly to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate. The invention and development of the printing press has played a vital role in the dissemination of human civilization and culture. However, in existing printing presses, the surface of the paper often contains fine dust during the printing process. This dust not only affects the transport of the paper but also impacts print quality during printing. Furthermore, most existing pressure rollers are rigidly connected, making it difficult to control the pressure applied to the thin paper. Therefore, we provide a newspaper conveying device for printing presses to solve these problems. Utility Model Content

[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a newspaper conveying device for a printing press, including a main body, a conveying line in the inner cavity of the main body, two corresponding pressing rollers above the conveying line, two dust collection cylinders rotatably arranged on the input side of the inner cavity of the main body, the bottom dust collection cylinder being arranged close to the conveying line, a dust collection box fixedly arranged on the outer wall of the main body corresponding to one of the shaft ends of the dust collection cylinder, an induced draft fan being installed on the dust collection box, and isolation plates being provided on the outer walls of both dust collection cylinders;

[0004] The outer wall of the dust collection cylinder is provided with several dust collection slots at equal intervals, and several sponge strips are fixedly installed on the outer wall of the dust collection cylinder. The sponge strips are interlaced with the dust collection slots. The sponge strips on the bottom of the dust collection cylinder can contact the conveyor line. The shaft ends of the dust collection cylinders corresponding to the dust collection box are all hollow designs, and the other end is connected to a motor. The motor is installed on the outer wall of the main body through a connecting bracket. Gears are fixedly installed on the shaft ends of the two dust collection cylinders corresponding to the motors. The two gears mesh with each other, and the output shaft of the motor is fixedly connected to one of the gears.

[0005] Preferably, the induced draft fan is installed on the outer wall of the dust collection box, and the input end of the induced draft fan is fixedly inserted through the outer wall of the dust collection box, while the output end of the induced draft fan is detachably equipped with a filter bag.

[0006] Preferably, the rotational speed of the dust collection cylinder is twice the rotational speed of the conveyor rollers.

[0007] Preferably, a cylinder is provided between the two pressing rollers. The cylinder is installed through the top of the main body. A fixed plate is fixedly provided at the movable end of the cylinder. Several limiting rods are movably passed through the interior of the fixed plate. A connecting plate is fixedly provided at the bottom end of the several limiting rods. Several springs are provided between the connecting plate and the fixed plate. The springs are sleeved on the outer wall of the limiting rods. Both pressing rollers are rotatably disposed at the bottom of the connecting plate.

[0008] The beneficial technical effects of this utility model are as follows: By setting two dust collection cylinders on the input side of the conveyor line, the conveyor device can remove dust from both sides of the paper at the same time. At the same time, the sponge strip can remove dust from the conveyor line simultaneously, ensuring the overall cleanliness of the paper and the conveyor line. This allows the paper to be printed stably after passing through the conveyor line. With the setting of the arc-shaped isolation plate, the dust collection channels of the dust collection trough are all on the surface of the paper and the conveyor line, further improving the dust collection intensity and making reasonable use of wasted resources.

[0009] Through the design of the connecting plate and the fixing plate, the downward pressure of the cylinder under the action of the spring and the limiting rod can ensure the degree of pressure of the pressure roller on the paper on the conveyor line, and avoid the situation where the pressure on the paper is too loose or too tight.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] This utility model proposes a newspaper conveying device for a printing press, including a body 1, a conveying line 2 in the inner cavity of the body 1, two corresponding pressing rollers 3 above the conveying line 2, two dust collection cylinders 4 rotatably arranged on the input side of the inner cavity of the body 1 through sealed bearings, the bottom dust collection cylinder 4 is arranged close to the conveying line 2, a dust collection box 5 is fixedly arranged on the outer wall of the body 1 corresponding to one of the shaft ends of the dust collection cylinder 4, a blower 6 is installed on the dust collection box 5, and an isolation plate 7 is provided on the outer wall of both dust collection cylinders 4.

[0016] The outer wall of the dust collection cylinder 4 is provided with several dust collection grooves 41 at equal intervals, and several sponge strips 42 are fixedly installed on the outer wall of the dust collection cylinder 4. The sponge strips 42 are interlaced with the dust collection grooves 41. The sponge strips 42 on the bottom dust collection cylinder 4 can contact the conveyor line 2. The shaft end of the dust collection cylinder 4 on the side corresponding to the dust collection box 5 is designed as a cavity, and the other end is connected to a motor 45. The motor 45 is installed on the outer wall of the main body 1 through a connecting bracket 43. Gears 44 are fixedly installed on the shaft end of the two dust collection cylinders 4 corresponding to the motor 45. The two gears 44 mesh with each other, and the output shaft of the motor 45 is fixedly connected to one of the gears 44.

[0017] By setting two dust collection cylinders 4 on the input side of the conveyor line 2, dust can be removed from both sides of the paper at the same time. Meanwhile, the sponge strip 42 can also remove dust from the conveyor line 2 simultaneously, ensuring the overall cleanliness of the paper and the conveyor line 2. This allows the paper to be printed stably after passing through the conveyor line 2. With the setting of the arc-shaped isolation plate 7, the dust collection channels of the dust collection trough 41 are all on the surface of the paper and the conveyor line 2, further improving the dust collection intensity and making reasonable use of wasted resources.

[0018] Specifically, the induced draft fan 6 is installed on the outer wall of the dust collection box 5, and the input end of the induced draft fan 6 is fixedly inserted through the outer wall of the dust collection box 5. The output end of the induced draft fan 6 is detachably equipped with a filter bag 61. This design can collect dust and facilitate cleaning after the filter bag 61 is filled with dust.

[0019] Specifically, the rotational speed of the dust collection cylinder 4 is twice the rotational speed of the rollers of the conveyor line 2. This speed ensures a speed difference with the conveyor line 2, thereby improving the cleaning ability of the conveyor line 2.

[0020] Specifically, a cylinder 31 is provided between the two pressing rollers 3. The cylinder 31 is installed through the top of the main body 1. A fixed plate 32 is fixedly provided at the movable end of the cylinder 31. Several limiting rods 33 are movably passed through the interior of the fixed plate 32. A connecting plate 34 is fixedly provided at the bottom end of the several limiting rods 33. Several springs 35 are provided between the connecting plate 34 and the fixed plate 32. The springs 35 are sleeved on the outer wall of the limiting rods 33. Both pressing rollers 3 are rotatably provided at the bottom of the connecting plate 34.

[0021] Through the design of the connecting plate 34 and the fixing plate 32, under the action of the spring 35 and the limiting rod 33, the downward pressing of the cylinder 31 can ensure the degree of pressing of the pressing roller 3 on the paper on the conveyor line 2, and avoid the situation where the pressing of the paper is too loose or too tight.

[0022] It should be noted that the cross-section of the limiting rod 33 is convex, thus ensuring that the limiting rod 33 can always be connected to the fixing plate 32.

[0023] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0024] Working principle: When using this conveying device, the paper roll can be passed through the conveyor line 2 and the pressure roller 3, and the cylinder 31 is started to drive the pressure roller 3 to press down. At this time, the motor 45, the conveyor line 2 and the blower 6 are started. The operation of the conveyor line 2 can drive the paper to move from the input side to the output side. During this process, the motor 45 can drive the two dust collection cylinders 4 to rotate synchronously through the meshing of two gears 44. This allows the sponge strips 42 on the two dust collection cylinders 4 to remove dust from both sides of the paper and the outer surface of the conveyor line 2. At the same time, under the action of the blower 6, negative pressure is generated on both sides of the paper and the outer surface of the conveyor line 2. The dust that is hung by the sponge strips 42 can enter the dust collection box 5 through the dust collection trough 41, and finally filter the dust through the filter bag 61. This conveying method not only ensures that both sides of the paper are clean, but also ensures the cleanliness of the conveyor line 2, further improving the printing quality of the paper.
