Description

Technical Field

[0001] This utility model belongs to the field of printing positioning technology, and more specifically, it relates to a positioning calibration device for printing. Background Technology

[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, and leather to mass-produce the content of the original manuscript, including text, pictures, photographs, and anti-counterfeiting materials. During the printing process, positioning and calibration are required before printing to ensure the accuracy of the printing position.

[0003] Application number CN202021025503.1 discloses a feeding end positioning calibration device for cardboard printing, including a base, a printing table fixedly mounted on the upper part of the base, a conveyor belt fixedly mounted on the upper part of the printing table, a rotating shaft fixedly mounted inside the conveyor belt, a pulley fixedly mounted on one side of the rotating shaft, a belt movably mounted on the pulley, and the other end of the belt movably mounted on the output end of a motor. A fixing frame is fixedly mounted on the upper part of one end of the base, and a cover plate is fixedly mounted on the upper part of the fixing frame. This feeding end positioning calibration device for cardboard printing calibrates the direction of the cardboard above the conveyor belt by fixing a calibration plate fixedly on the upper part of the conveyor belt and movably mounting a roller inside the calibration plate. The roller, with two symmetrically mounted S-shaped calibration plates, increases the flexibility of the cardboard and calibration plate, facilitating the transmission of the cardboard above the conveyor belt.

[0004] Based on the above patent search and understanding of the application of existing printing positioning and calibration devices: Traditional printing positioning calibration devices are difficult to adjust the calibration spacing flexibly when dealing with printing materials of different widths, resulting in an inability to accurately adapt to diverse printing needs and a tendency for material positioning deviations. In some devices, the calibration structure and the conveying mechanism are independent of each other. During the material conveying process, the calibration operation may hinder the normal transmission of the material, affect the printing efficiency, and the material position is prone to shift after calibration. The existing equipment lacks an effective dynamic adjustment mechanism when positioning materials. When the material deviates slightly during the transportation process, it cannot be calibrated in time, resulting in inaccurate final printing position. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a positioning calibration device for printing. This addresses the shortcomings of existing traditional printing positioning calibration devices, such as difficulty in flexibly adjusting the calibration spacing when dealing with printing materials of varying widths. This results in an inability to accurately adapt to diverse printing needs, leading to material positioning deviations. Furthermore, the calibration structure and conveying mechanism of some devices are independent, potentially hindering normal material transport during material conveying and affecting printing efficiency. Additionally, the material position is prone to shifting after calibration. Moreover, existing devices lack an effective dynamic adjustment mechanism when positioning materials, failing to promptly calibrate when slight material shifts during transport, resulting in inaccurate final printing positions.

[0006] The technical solution adopted in this utility model is as follows: A positioning and calibration device for printing includes a frame; a strip groove is provided at the top center of the frame; a positioning seat is fixedly connected to the lower center of the frame; a motor A is fixedly connected to the rear center of the positioning seat; the shaft of motor A is threaded and located at the upper center of the positioning seat; an extension member is slidably connected to the top of the positioning seat; a threaded hole is provided at the lower front end of the extension member, and the shaft of motor A is located in the threaded hole of the extension member; the extension member is located in the strip groove of the frame; and a retractable trapezoidal plate is provided inside the extension member.

[0007] According to one embodiment of the present invention, a limiting frame is fixedly installed in the middle position inside the device frame, and a motor B is fixedly installed in the middle position on the right side of the limiting frame.

[0008] According to one embodiment of the present invention, a bidirectional screw is rotatably connected to the middle position inside the limiting frame, and the right side of the bidirectional screw is fixedly connected to the rotating shaft of motor B.

[0009] According to one embodiment of the present invention, a sliding block is slidably connected to the left and right sides of the inner side of the limiting frame. The two sliding blocks are symmetrically designed, and a threaded hole is opened in the middle of the side of each sliding block. The threads of the two sliding blocks are designed to be in opposite positions. The left and right sides of the bidirectional screw are respectively inserted into the threaded hole of a sliding block.

[0010] According to one embodiment of the present invention, the top middle position of each sliding block is fixedly connected to the bottom outer position of a conveyor, and the two conveyors are symmetrically designed.

[0011] According to one embodiment of the present invention, the top middle two sides of the device frame are fixedly connected to the bottom left and right sides of the printing machine. The printing machine is located inside the two conveyors on both sides. The extension member is located in the middle of the two conveyors. When the extension member is retracted, the trapezoidal plate is lower than the top of the conveyor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Motor B drives the bidirectional screw to rotate, causing two sliding blocks to slide in opposite directions along the inside of the limit frame, thereby moving the two conveyors. The distance between the conveyors can be flexibly adjusted, and it can accurately adapt to printing paperboards of different widths, greatly improving the applicability of the device.

[0013] The extension component has an internally retractable trapezoidal plate. When the printing material needs to be positioned and calibrated, the extension component extends, and the trapezoidal plate positions the material to ensure that the material is accurately delivered to the bottom of the printing press for printing. After printing, the extension component retracts, and the trapezoidal plate is lower than the top of the conveyor, which does not affect the normal material delivery. This achieves coordinated operation of calibration and delivery, improving printing efficiency.

[0014] Motor A drives the extension component to slide on top of the positioning seat, which can precisely adjust the distance between the extension component and the printing press. When the extension component extends, the front end of the printing paperboard contacts the trapezoidal plate, which ensures that the printing position of the printing paperboard is directly below the printing press. This effectively improves the accuracy of positioning calibration, ensures printing quality, reduces the workload of operators, reduces human error, and improves the stability and reliability of the device.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a positioning and calibration device for printing, including a device frame 1; a strip groove is provided at the top center of the device frame 1, a positioning seat 102 is fixedly connected to the lower center of the device frame 1, a motor A103 is fixedly connected to the rear center of the positioning seat 102, the shaft of the motor A103 is threaded, and the shaft of the motor A103 is located at the upper center of the positioning seat 102, an extension member 104 is slidably connected to the top of the positioning seat 102, a threaded hole is provided at the lower front end of the extension member 104, the shaft of the motor A103 is located in the threaded hole of the extension member 104, the extension member 104 is located in the strip groove of the device frame 1, and an extendable and retractable trapezoidal plate is provided inside the extension member 104.

[0024] Among them, a limit frame 2 is fixedly installed in the middle position inside the device frame 1, and a motor B201 is fixedly installed in the middle position on the right side of the limit frame 2.

[0025] The limiting frame 2 has a bidirectional screw 202 rotatably connected to the middle position inside, and the right side of the bidirectional screw 202 is fixedly connected to the shaft of the motor B201.

[0026] The limiting frame 2 has a sliding block 203 slidably connected to the left and right sides of its interior. The two sliding blocks 203 are symmetrically designed, and each sliding block 203 has a threaded hole in the middle of its side. The threads of the two sliding blocks 203 are designed to be opposite. The two sides of the bidirectional screw 202 are respectively inserted into the threaded holes of the sliding block 203.

[0027] Each sliding block 203 is fixedly connected at the top center to the bottom outer side of a conveyor 204, and the two conveyors 204 are designed symmetrically.

[0028] The top middle two sides of the device frame 1 are fixedly connected to the bottom left and right sides of the printing machine 101. The printing machine 101 is located inside the two conveyors 204 on both sides. The extension member 104 is located in the middle of the two conveyors 204. When the extension member 104 is retracted, the trapezoidal plate is lower than the top of the conveyor 204.

[0029] When using: First, place the cardboard to be printed behind the two conveyors 204. Based on the width of the printing material, motor B201 is started, driving the bidirectional screw 202 to rotate. Since the threads of the two sliding blocks 203 are designed in opposite directions, when the bidirectional screw 202 rotates, the two sliding blocks 203 slide in opposite directions along the inside of the limit frame 2, thereby driving the two conveyors 204 to move and adjusting the distance between them to accommodate printing paperboards of different widths, while ensuring the paperboard is centered.

[0030] When the printing material needs to be positioned and calibrated, motor A103 is started. The shaft of motor A103 rotates. Since the shaft has threads that mate with the threaded hole of the extension member 104, the extension member 104 is driven to slide on the top of the positioning seat 102. The distance between the extension member 104 and the printing machine 101 is adjusted. After the extension member 104 extends, the front end of the printing paperboard contacts the trapezoidal plate extended by the extension member 104, ensuring that the printing position of the printing paperboard is directly below the printing machine 101, thus completing the subsequent printing steps.

[0031] The printing paperboard is conveyed forward by the conveyor 204. The trapezoidal plate of the extension member 104 positions and calibrates the material to ensure that the material is accurately conveyed to the bottom of the printing press 101 for printing. After printing is completed, the extension member 104 can be retracted so that the trapezoidal plate is lower than the top position of the conveyor 204, without affecting the normal conveying of the material.

While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments.
