Description

Technical Field

[0001] This utility model relates to the field of origami device technology, and more specifically to an adaptive origami device for multiple paper sizes. Background Technology

[0002] Existing paper production lines include paper feeding devices, rolling devices, folding devices, and paper cutting devices. Multiple production processes work together. The folding device is a machine used to fold paper. There are two-fold and four-fold folding machines, also known as automatic or fully automatic folding machines. They are widely used for the mass folding of product manuals, official documents, and business letters. The paper that needs to be bent is placed on the feeding rack. The paper enters the equipment and is fed into the folding tray by the bending mechanism. The tray works with the baffle to bend the paper.

[0003] In existing paper folding devices, paper is fed by placing it on a feeding rack. However, the existing feeding rack does not have an adjustment and limit mechanism. When feeding paper of different sizes, it is necessary to manually adjust the paper to fit the feeding port of the paper folding device, which reduces the working efficiency of the paper folding device. Utility Model Content

[0004] The purpose of this invention is to provide a multi-size paper adaptive folding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a multi-specification paper adaptive folding device, including a folding machine body. A feed inlet is provided on one side of the folding machine body, and a feed plate is fixedly installed inside the feed inlet. The feed plate is inclined and has a conveying mechanism. The conveying mechanism includes a first conveying roller. Two fixed plates are fixedly installed on the feed plate, one of which has a first motor fixedly installed. A second conveying roller is located below the first conveying roller. A limiting mechanism is provided on the feed plate, including a lead screw. An installation groove is formed on the feed plate, and the lead screw is rotatably installed within the installation groove. A second motor is fixedly installed on the outer wall of the folding machine body. Two threaded sleeves are threaded onto the lead screw. A connecting block is fixedly installed on the top of each of the two threaded sleeves. The tops of both connecting blocks extend into the installation groove and are fixedly fitted with a limiting plate.

[0006] As a further improvement to this technical solution, the first conveying roller is rotatably disposed between two fixed plates, and the output end of the first motor is fixed to the first conveying roller.

[0007] As a further improvement to this technical solution, the feed plate is provided with a groove adapted to the second conveying roller, and mounting blocks are rotatably provided at both ends of the second conveying roller. Springs are fixedly provided at the bottom of the two mounting blocks, and the bottom ends of the springs are fixed to the feed plate.

[0008] As a further improvement to this technical solution, the output end of the second motor is fixed to the lead screw, and the lead screw is provided with two sections of threads with opposite directions.

[0009] As a further improvement to this technical solution, a limiting block is fixedly provided at the bottom of the screw sleeve, and a limiting groove adapted to the limiting block is provided at the bottom of the mounting groove on the feed plate.

[0010] As a further improvement to this technical solution, an infrared sensor is fixedly installed on the side wall of the limiting plate, and an infrared receiver is fixedly installed on the side wall of the connecting block. The infrared sensor and the infrared receiver are compatible.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up a conveying mechanism, the paper is supported by the second conveying roller, reducing the resistance of paper feeding. The elastic force of two springs drives two mounting blocks to move upward, and the two mounting blocks drive the second conveying roller to move upward, so that the second conveying roller and the first conveying roller clamp the paper. The second conveying roller can float up and down, thus making it suitable for paper of different thicknesses.

[0013] 2. By setting a limit mechanism, the second motor drives the lead screw to rotate, which in turn drives the two limit plates to contact the two sides of the paper to limit the paper, so that paper of different widths can be fed smoothly. When the infrared receiver does not receive the signal from the infrared sensor, the second motor is controlled to stop operating, automatically adjusting and adapting, saving manpower and resources and being easy to use.

[0021] Please see Figures 1-3As shown, this utility model provides a multi-size paper adaptive folding device, including a folding machine body 1. A feed inlet 2 is provided on one side of the folding machine body 1, and a feed plate 3 is fixedly arranged inside the feed inlet 2. The feed plate 3 is inclined. By placing paper on the feed plate 3, the paper enters the feed inlet 2 along the inclined feed plate 3. The paper enters the folding machine body 1 through the feed inlet 2 for folding processing. A conveying mechanism 4 is provided on the feed plate 3. The conveying mechanism 4 includes a first conveying roller 41. Two fixed plates 42 are fixedly arranged on the feed plate 3. The first conveying roller 41 is rotatably arranged between the two fixed plates 42. A first motor 43 is fixedly arranged on one of the fixed plates 42. The output end of the first motor 43 is fixed to the first conveying roller 41, allowing the paper to pass under the first conveying roller 41 and be folded by the first motor 43. The first conveyor roller 41 is rotated, and the paper is fed by the friction between the first conveyor roller 41 and the paper. A second conveyor roller 44 is provided below the first conveyor roller 41. The feed plate 3 has a groove that matches the second conveyor roller 44. Mounting blocks 45 are rotatably installed at both ends of the second conveyor roller 44. Springs 46 are fixed at the bottom of the two mounting blocks 45. The bottom of the springs 46 is fixed to the feed plate 3. The second conveyor roller 44 supports the paper and reduces the resistance of the paper feeding. The elastic force of the two springs 46 drives the two mounting blocks 45 to move upward. The two mounting blocks 45 drive the second conveyor roller 44 to move upward, so that the second conveyor roller 44 and the first conveyor roller 41 clamp the paper. The second conveyor roller 44 can float up and down, so it can be used for paper of different thicknesses.

[0022] A limiting mechanism 5 is provided on the feed plate 3. The limiting mechanism 5 includes a lead screw 51. The feed plate 3 has an installation groove, and the lead screw 51 is rotatably mounted in the installation groove. A second motor 53 is fixedly mounted on the outer wall of the folding machine body 1. The output end of the second motor 53 is fixed to the lead screw 51. Two threaded sleeves 52 are threadedly connected to the lead screw 51. The lead screw 51 has two sections of threads with opposite directions. A connecting block 54 is fixedly mounted on the top of each of the two threaded sleeves 52. The top of each of the two connecting blocks 54 extends out of the installation groove and is fixedly mounted with a limiting plate 55. The second motor 53 drives the lead screw 51 to rotate, thereby driving the two threaded sleeves 52 to move towards each other or in opposite directions. The two threaded sleeves 52 drive the two connecting blocks 54 to move synchronously. The two connecting blocks 54 drive the two limiting plates 55 to move synchronously. The screw sleeve 52 is fixedly mounted on the bottom of the screw sleeve 52 with a limit block 56. The feed plate 3 has a limit groove at the bottom of the mounting groove that matches the limit block 56. The limit block 56 limits the screw sleeve 52. An infrared sensor 57 is fixedly mounted on the side wall of the limit plate 55, and an infrared receiver 58 is fixedly mounted on the side wall of the connecting block 54. The infrared sensor 57 and the infrared receiver 58 are compatible. The infrared sensor 57 emits a signal and the infrared receiver 58 receives the signal. When the infrared receiver 58 does not receive the signal from the infrared sensor 57, it indicates that the limit plate 55 is in contact with the side of the paper. At this time, the second motor 53 is controlled to stop operating. The automatic adjustment and adaptation save manpower and resources and is easy to use.

[0023] The specific working principle of this utility model is as follows: Paper is passed between the first conveying roller 41 and the second conveying roller 44. The first conveying roller 41 is driven to rotate by the first motor 43. The paper is fed by the friction between the first conveying roller 41 and the paper. The second conveying roller 44 supports the paper, reducing the resistance to feeding. The elastic force of two springs 46 drives two mounting blocks 45 to move upwards. The two mounting blocks 45 drive the second conveying roller 44 to move upwards, clamping the paper between the second conveying roller 44 and the first conveying roller 41. The second conveying roller 44 can float up and down, making it suitable for paper of different thicknesses. The second motor 43... The machine 53 drives the lead screw 51 to rotate, which in turn drives the two screw sleeves 52 to move in opposite directions. The two screw sleeves 52 drive the two connecting blocks 54 to move synchronously, and the two connecting blocks 54 drive the two limit plates 55 to move synchronously. The two limit plates 55 contact the two sides of the paper to limit the paper, so that papers of different widths can be fed smoothly. The infrared sensor 57 emits a signal and the infrared receiver 58 receives the signal. When the infrared receiver 58 does not receive the signal from the infrared sensor 57, it indicates that the limit plate 55 is in contact with the side of the paper. At this time, the second motor 53 is controlled to stop operating. The machine automatically adjusts and adapts, saving manpower and resources and is easy to use.
