Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a material pressing component for a printing machine. Background Art

[0002] A printing machine is a machine used to print patterns or texts on various materials. In the field of clothing manufacturing, a printing machine is usually used to print patterns on fabrics. During the printing process, the pigment in the printing plate passes through the printing plate under the extrusion of a press scraper, thereby printing patterns or texts on the fabric. However, during the press process, air may be mixed into the pigment to form bubbles. The pigment containing bubbles will burst after being printed on the material. The pigment at the bursting point of the bubble will diffuse outward to form a circular mark, resulting in reduced printing quality. Therefore, a press component for a printing machine is proposed.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The first electric hydraulic cylinder 2 can drive the entire material pressing mechanism 5 to move forward and backward, so that the material pressing scraper 501 moves in the printing plate 4, so that the pigment is printed on the cloth. During the printing process, the vibration mechanism 6 recovers the high-frequency vibration of the material pressing scraper 501, so that the bubbles in the pigment are dispersed and burst.

[0019] like Figure 2 As shown, the pressing mechanism 5 includes a second electric hydraulic cylinder 506 fixedly connected to the output end of the first electric hydraulic cylinder 2, a lifting plate 504 is provided at the output end of the second electric hydraulic cylinder 506, a positioning rod 503 is provided on the lifting plate 504, a positioning frame 502 is movably mounted on the positioning rod 503, a pressing scraper 501 is fixedly mounted on the lower end of the positioning frame 502, a clamping spring 505 is sleeved on the positioning rod 503, one end of the clamping spring 505 is connected to the positioning frame 502, and the other end of the clamping spring 505 is connected to the lifting plate 504, a screw hole is provided on the lifting plate 504, and the positioning rod 503 is connected to the lifting plate 504 through the screw hole, the positioning frame 502 is movably mounted below the lifting plate 504 through the positioning rod 503, and the pressing scraper 501 is movably mounted above the printing plate 4 through the positioning frame 502.

[0020] Specifically, the second electric hydraulic cylinder 506 can drive the lifting plate 504 to move up and down, thereby driving the pressure scraper 501 on the positioning frame 502 to move up and down, so that the pressure scraper 501 can be pressed on the printing plate 4. After the pressure scraper 501 is pressed on the printing plate 4, the clamping spring 505 will provide downward pressure for the positioning frame 502, so that the pressure scraper 501 is pressed on the printing plate 4, and then during the movement of the pressure scraper 501, the pigment is squeezed through the printing plate 4 to print a pattern.

[0021] like Figure 3 As shown, the vibration mechanism 6 includes a positioning seat 604 fixed on both sides of the pressure scraper 501, a vibration steel bar 603 is fixedly installed in the positioning seat 604, a positioning cross bar 601 is fixedly installed on both sides of the printing plate 4, a driving paddle 602 is fixedly installed on the inner side of the positioning cross bar 601, a docking foot 605 is provided on the vibration steel bar 603, the vibration steel bar 603 is fixed in the positioning seat 604 through the docking foot 605, a positioning bar 606 is provided on the positioning cross bar 601, the positioning cross bar 601 is fixed to both sides of the printing plate 4 through the positioning bar 606, the driving paddle 602 is installed at intervals on the inner side of the positioning cross bar 601, and the driving paddle 602 and the vibration steel bar 603 are aligned with each other in the horizontal direction, and at the same time, the driving paddle 602 blocks the moving path of the vibration steel bar 603.

[0022] Specifically, the first electric hydraulic cylinder 2 can drive the material pressing scraper 501 to move forward, and the material pressing scraper 501 will drive the vibrating steel bar 603 to move forward when the material pressing scraper 501 moves forward. When the vibrating steel bar 603 moves forward, the driving paddle 602 will block the vibrating steel bar 603 from moving forward, causing it to accumulate force and deform. After the vibrating steel bar 603 passes through the driving paddle 602, the vibrating steel bar 603 will recover and generate high-frequency vibration. After the high-frequency vibration of the vibrating steel bar 603, it will drive the material pressing scraper 501 to vibrate at a high frequency, forcing the bubbles in the pigment to disperse and burst, thereby reducing the generation of marks. In the text, the first electric hydraulic cylinder 2 and the second electric hydraulic cylinder 506 are both electrically connected to the external power supply through the corresponding control switch. The first electric hydraulic cylinder 2 and the second electric hydraulic cylinder 506 are both prior art, and their specific structures, working principles and electrical connection relationships are not described in detail here.

[0023] It should be noted that the utility model is a material pressing component for a printing machine. In actual use, the pigment is first placed on the printing plate 4. After the pigment is placed on the printing plate 4, the second electric hydraulic cylinder 506 can be started to make the lifting plate 504 move downward and resist the printing plate. Then the first electric hydraulic cylinder 2 can be started. After starting the first electric hydraulic cylinder 2, it will drive the entire material pressing mechanism 5 to move back and forth, so that the material pressing scraper 501 moves in the printing plate 4. During the movement of the material pressing scraper 501 in the printing plate 4, the pigment will be squeezed through the printing plate 4, so as to print a pattern. In the process of the forward and backward movement of the material pressing mechanism 5, the vibrating steel bar 603 will also move back and forth, so that the driving paddle 602 is used to pry one end of the vibrating steel bar 603, so that the vibrating steel bar 603 vibrates at a high frequency. After the high-frequency vibration of the vibrating steel bar 603, it will drive the material pressing scraper 501 to vibrate at a high frequency, so that the bubbles in the pigment are dispersed and broken, so that the pigment is evenly printed on the surface of the cloth, reducing the generation of marks and improving the printing quality.
