Description

Technical Field

[0001] The utility model relates to the technical field of textile printing equipment, in particular to a printing device with self-adapting scraper pressure and inclination. Background Art

[0002] In textile printing production, the amount of colorant applied affects the depth of the printed color tone. For halftone printing represented by nine-color printing, the amount of colorant applied has a greater impact on the printing effect, because the colors in the halftone printing pattern are achieved by the overlapping and juxtaposition of dots. Different amounts of colorant applied will be directly reflected in the tone performance. Scraper pressure and scraping inclination are key factors affecting the amount of colorant applied.

[0003] A Chinese patent with publication number CN219503123U discloses a scraper structure with adjustable height. It is adjusted by a sliding adjustment component, which drives the adjustment plate to move outside the adjustment fixing component to achieve the function of adjusting the scraper height. The scraper is initially fixed by a fixing screw through the through hole of the scraper fixing plate. The threaded rod is driven to rotate by a dual-axis rotation motor, which drives the L-shaped limit block to move and fix the scraper for a second time to play a reinforcement role. At the same time, the function of disassembling and replacing the scraper is achieved. The scraper cleaning and wiping component is driven to rotate by rotating the hand crank to facilitate wiping of residual slurry on the scraper.

[0004] Although the device can adjust the height of the scraper by adjusting the component, the inclination angle of the scraper can only be adjusted by replacing the scraper. Replacing the scraper requires stopping the machine for replacement, which not only causes a decrease in the factory's production capacity, but also requires certain skills and proficiency of the workers, and the adjustment efficiency is low. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a printing device with adaptive scraper pressure and inclination, which effectively solves the problem that the existing scraper adjustment device can only adjust the scraper inclination angle by replacing the scraper, and replacing the scraper requires stopping the machine for replacement, which not only causes a decrease in factory production capacity, but also the replacement and adjustment also has certain requirements on the workers' skill proficiency and low adjustment efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a scraper pressure and inclination adaptive printing device, including a control frame, a clamping member and a fixed plate, a lifting frame is arranged in the control frame, and a lifting assembly for lifting and moving the lifting frame is arranged on the control frame, the clamping member is rotatably connected in the lifting frame, and a scraper is detachably installed in the clamping member, the fixed plate is fixedly connected to the lifting frame, a first hinged seat is installed on the fixed plate, an electric push rod is hinged in the first hinged seat, the telescopic end of the electric push rod is hinged with a second hinged seat, and the second hinged seat is installed on the clamping member.

[0007] Furthermore, the lifting assembly includes a bidirectional motor installed on a control frame, the output shaft of the bidirectional motor is installed with a screw, the lifting frame is threadedly connected to the screw, and one end of the screw away from the bidirectional motor is fixedly connected to a limiting block.

[0008] Furthermore, guide blocks are fixedly connected to both sides of the inner wall of the control frame, guide grooves are opened at both ends of the lifting frame, and the lifting frame is slidably connected to the guide blocks through the guide grooves.

[0009] Furthermore, the clamping member includes a mounting frame and a connecting shaft, both ends of the connecting shaft are rotatably connected to the lifting frame, and the connecting shaft is fixedly connected to connecting blocks arranged at equal distances, and the bottom end of the connecting block is fixedly connected to the mounting frame.

[0010] Furthermore, an installation cavity is provided on the mounting frame, a clamp is provided in the installation cavity, a through hole is provided on the clamp, a fixing bolt is provided in the through hole, a fixing screw is fixedly connected to the inner wall of the installation cavity, one end of the fixing bolt passes through the through hole and is threadedly connected to the fixing screw, and the scraper is arranged between the clamp and the mounting frame.

[0011] Furthermore, both side surfaces of the scraper are provided with card slots, and the side surfaces of the clamping plate and the mounting frame close to each other are fixedly connected with card blocks, and the card blocks match the card slots.

[0012] Furthermore, a positioning tube is fixedly connected in the installation cavity, a positioning rod is fixedly connected on the clamping plate, and one end of the positioning rod away from the clamping plate is inserted into the positioning tube.

[0013] Furthermore, L-shaped connecting pieces are installed on both side surfaces of the control frame by bolts.

[0014] The beneficial effects of the above technical solution are:

[0015] The utility model adopts the matching arrangement among a lifting assembly, a lifting frame, a clamping member, a fixing plate, a first hinge seat, an electric push rod and a second hinge seat. The height of the lifting frame in the control frame can be adjusted by the lifting assembly, so that the pressure between the scraper on the clamping member and the printing surface can be adjusted. The extension or retraction of the telescopic end of the electric push rod can drive the lifting frame on the clamping member to rotate, so as to adjust the scraping angle of the scraper. The pressure and angle of the scraper are adjusted by electric control, which not only does not require the scraper to be disassembled for adjustment, but also has high adjustment efficiency and does not require the proficiency of the workers.
