Description

Technical Field

[0001] This utility model relates to the field of printing press limit baffle technology, and in particular to a printing press with an adjustable limit baffle. Background Technology

[0002] A printing press is a mechanical device used to transfer text, images, or patterns onto substrates (such as paper, plastic, and fabric) in batches using pressure or non-contact technologies (such as inkjet and laser). Its core function is to achieve efficient and large-scale information dissemination or product processing by replicating the content of the original. In a printing press, limit plates are installed on the left and right side baffle areas of the paper feeding device. The distance between the side baffles is adjusted by a lead screw or motor to assist in paperboard alignment. To ensure smooth paper feeding and prevent paper deviation, a printing press with adjustable limit plates is proposed to correct the paper position. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a printing machine with an adjustable limit baffle, which effectively solves the deficiencies of the prior art.

[0004] To achieve the above objectives, one embodiment of this utility model provides a printing machine with adjustable limiting baffles, including a frame. A housing is installed at the top of the frame. Two vertically placed lifting components and two first guide columns are respectively installed at the four corners of the frame, and a paper placement plate is installed between the four components. Mounting plates are installed on both sides of the paper placement plate. The ends of the two mounting plates are bent upwards, and the tops of the two mounting plates are equipped with opposing lateral limiting plates. A paper guide is installed on one side of the frame. Two fixed seats are installed at the top of the paper guide. Two second guide columns and a bidirectional lead screw are installed between the two fixed seats. A first motor is installed on the side of one of the fixed seats, and its output end is fixedly connected to the end of the bidirectional lead screw. Two movable seats are symmetrically installed on the outer walls of the two second guide columns and the bidirectional lead screw. Vertically placed limiting baffles are installed on the bottom surfaces of the two movable seats.

[0005] Preferably, in any of the above solutions, a paper placement opening is provided on the side of the outer casing away from the paper guide section. The outer casing is fixedly connected to the frame by bolts. This solution facilitates the bending and covering of the frame by the outer casing, while providing an installation position for the paper feeding mechanism. The paper placement opening allows operators to replenish paper through this position, ensuring continuous and efficient printing.

[0006] Preferably, in any of the above embodiments, the two lifting components include a second motor and a drive screw. One second motor is fixedly connected to the fixed base, and the other second motor is fixedly connected to the side wall of the housing. In this embodiment, the drive screw is threadedly connected to the two corners of the paper placement plate, which facilitates the use of the screw and nut mechanism to lift the position of the paper placement plate and the paper, allowing the paper to gradually rise in height and cooperate with the paper feeding mechanism to achieve paper transmission. In addition, the two first guide posts facilitate the guidance of the other two corners of the paper placement plate, ensuring that the paper placement plate can rise vertically.

[0007] Preferably, the bottom ends of the two mounting plates are fixedly connected to both ends of the paper placement plate by bolts. Electric cylinders are installed on the opposite sides of the two mounting plates. The output ends of the two electric cylinders are fixedly connected to the two lateral limiting plates respectively. This method facilitates the provision of power to the two lateral limiting plates. At the same time, the two electric cylinders are precisely controlled by a controller to ensure accurate adjustment of the two lateral limiting plates, which facilitates the limiting of paper stacking.

[0008] Preferably, in any of the above solutions, a plurality of electric rollers are installed in the middle of the paper guide section, and the top surfaces of the plurality of electric rollers protrude from the top surface of the paper guide section. This solution facilitates the conveying of paper and guides it to the subsequent printing unit for printing operations.

[0009] Preferably, in any of the above solutions, there is a gap between the two limiting baffles and the sides of the two lateral limiting baffles, and a notch is left on the bottom surface of the two limiting baffles near the electric roller. The notch in this solution avoids motion interference with the outer wall of the electric roller, and at the same time reduces the distance between the limiting baffles and the electric roller, which facilitates the limiting and guiding of the paper.

[0010] This utility model has the following advantages:

[0011] 1. This printing press with adjustable limiting baffles features two lateral limiting plates and two electric cylinders. The two electric cylinders push the lateral limiting plates to move in opposite directions, simultaneously cooperating with the side wall of the frame to limit the placement of paper. A bidirectional lead screw, two second guide columns, and a first motor are also included. The first motor, when energized, drives two moving seats and two limiting plates to move relative to or in opposite directions, adjusting the distance between the two limiting plates. This facilitates the limiting and guiding of the paper, ensuring precise entry into the subsequent printing section. The overall structure is simple, the design is reasonable, and it is easy to promote and use.

[0012] 2. This printing press with adjustable limit baffle is equipped with two drive screws, two second motors, two first guide columns, and a paper placement plate. The two drive screws are threaded to the two corners of the paper placement plate. The two second motors are powered on and drive the paper placement plate to move vertically, thereby lifting the paper and facilitating the paper suction action. It has a simple structure, runs smoothly, and facilitates the paper conveying. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] like Figures 1 to 5 As shown, a printing press with an adjustable limit baffle includes a frame 1, a housing 2 mounted on the top of the frame 1, and a paper feeding mechanism mounted on the top wall of the housing 2. The paper feeding mechanism includes:

[0021] 1. Air blowing system: including loosening nozzle (to loosen the paper) and pressing nozzle (to separate the paper). The air volume can be adjusted by the air valve. The loosening nozzle blows air towards the top of the paper stack to loosen the top 5-10 thin sheets or 2-3 thick sheets, ensuring that the paper is separated one by one.

[0022] 2. Paper suction system: The paper separation nozzle and the paper delivery nozzle use vacuum suction to grasp and transfer paper. The paper separation nozzle moves downward and sucks up the top single sheet of paper, then lifts up and tilts backward to prevent sucking up multiple sheets of paper.

[0023] 3. Positioning mechanism: The paper stop, side plate, and rear plate work together to maintain the neatness of the paper stack edges and the accuracy of the conveying position. The paper delivery nozzle receives the paper released by the paper separation nozzle and conveys the paper to the paper feed roller through a straight or arc trajectory, and finally the paper feed roller conveys it to the printing unit.

[0024] 4. Drive mechanism: Cam and eccentric wheel control the timing of the action of the paper pressing nozzle and the paper separating nozzle to ensure that all components work together.

[0025] Two vertically placed lifting components 16 and two first guide columns 14 are installed at the four corners of the frame 1, and a paper placement plate 3 is installed between the four. Mounting plates 5 are installed on both sides of the paper placement plate 3. The ends of the two mounting plates 5 are bent upwards, and the tops of the two are equipped with opposing lateral limiting plates 4. Horizontal guide rods 7 are installed on the sides of the lateral limiting plates 4 that are far apart from each other. Multiple horizontal guide rods 7 are slidably connected to the two mounting plates 5, which facilitates the limiting of the two lateral limiting plates 4 and makes the two lateral limiting plates 4 move stably.

[0026] A paper guide 12 is installed on one side of the frame 1. The paper guide 12 is placed horizontally and docks with the subsequent printing unit. Two fixed seats 17 are installed at the top of the paper guide 12. Two second guide columns 9 and a bidirectional lead screw 10 are installed between the two fixed seats 17. A first motor 18 is installed on the side of one fixed seat 17, and its output end is fixedly connected to the end of the bidirectional lead screw 10. Two movable seats 8 are symmetrically installed on the outer walls of the two second guide columns 9 and the bidirectional lead screw 10. Vertically placed limit baffles 13 are installed on the bottom surface of the two movable seats 8. The limit baffles 13 have notches near the side limit plates 4 to facilitate air circulation and prevent air from causing the paper to bend or run crookedly.

[0027] A paper placement opening is provided on the side of the outer casing 2 away from the paper guide part 12. The outer casing 2 is fixedly connected to the frame 1 by bolts. As an optional technical solution of this utility model, this makes it easy to bend and cover the frame 1 with the outer casing 2, while providing an installation position for the paper feeding mechanism. The paper placement opening makes it easy for the operator to replenish the paper through this position, ensuring continuous and efficient printing.

[0028] The two lifting components include a second motor 1601 and a drive screw 1602. One second motor 1601 is fixedly connected to the fixed base 17, and the other second motor 1601 is fixedly connected to the side wall of the outer casing 2. As an optional technical solution of this utility model, the drive screw 1602 is threadedly connected to the two corners of the paper placement plate 3, which facilitates the use of the screw and nut mechanism to lift the position of the paper placement plate 3 and the paper, so that the paper can be gradually raised and cooperate with the paper feeding mechanism to realize the transmission of the paper. In addition, the two first guide posts 14 facilitate the guidance of the other two corners of the paper placement plate 3 to ensure that the paper placement plate 3 can rise vertically.

[0029] The bottom ends of the two mounting plates 5 are fixedly connected to the two ends of the paper placement plate 3 by bolts. Electric cylinders 6 are installed on the opposite sides of the two mounting plates 5. The output ends of the two electric cylinders 6 are fixedly connected to the two lateral limiting plates 4 respectively. As an optional technical solution of this utility model, this facilitates the provision of power to the two lateral limiting plates 4. At the same time, the two electric cylinders 6 are precisely controlled by a controller to ensure that the two lateral limiting plates 4 are precisely adjusted, which facilitates the limiting of paper stacking.

[0030] Multiple electric rollers 11 are installed in the middle of the paper guide section 12. The top surfaces of the multiple electric rollers 11 protrude from the top surface of the paper guide section 12. As an optional technical solution of this utility model, this facilitates the conveying of paper and guides it to the subsequent printing unit for printing operation.

[0031] A gap is left between the two limiting baffles 13 and the sides of the two lateral limiting plates 4. A notch is left on the bottom surface of the two limiting baffles 13 near the electric roller 11. As an optional technical solution of this utility model, the notch avoids movement interference between the limiting baffles 13 and the outer wall of the electric roller 11, and at the same time reduces the distance between the limiting baffles 13 and the electric roller 11, which facilitates the limiting and guiding of the paper.

[0032] This type of printing machine with adjustable limit baffle requires the following steps to use:

[0033] 1) When in use, depending on the size of the paper, the two electric cylinders 6 are activated to push the two side limit plates 4 to move horizontally, and then the paper is stacked on the paper placement plate 3.

[0034] 2) The two second motors 1601 are powered on and rotate synchronously to drive the paper placement plate 3 and the paper to move upward synchronously, which facilitates the paper feeding mechanism to perform paper feeding operations.

[0035] 3) The first motor 18 is powered on and runs, driving the bidirectional lead screw 10 to rotate, adjusting the distance between the two limit baffles 13 to facilitate the guidance of the paper.

[0036] In summary, during operation, the user utilizes two lateral limiting plates 4 and two electric cylinders 6. The two electric cylinders 6 push the lateral limiting plates 4 to move in opposite directions, simultaneously cooperating with the side wall of the frame 1 to limit the placement of the paper. A bidirectional lead screw 10, two second guide columns 9, and a first motor 18 are also included. When the first motor 18 is energized, it drives the two moving seats 8 and the two limiting plates 13 to move relative to or in opposite directions, adjusting the distance between the two limiting plates 13 to facilitate limiting and guiding the paper, and ensuring precise placement. The subsequent printing section has a simple overall structure and reasonable design, making it easy to promote and use. It is equipped with two drive screws 1602, two second motors 1601, two first guide columns 14, and a paper placement plate 3. The two drive screws 1602 are threaded to the two corners of the paper placement plate 3. The two second motors 1601 are powered on and drive the paper placement plate 3 to move vertically, thereby lifting the paper and facilitating the paper picking action. Its structure is simple, its operation is stable, and it is easy to realize the paper conveying.
