Technical Field
[0001] The utility model relates to the technical field of screen printing, in particular to a printing head lifting mechanism. Background Art
[0002] The print head is the main component of a printing machine, especially a screen printing machine. There is a printing scraper on the print head, which moves back and forth on the screen to scrape the printing ink and print the printing ink onto the product. According to different printing process requirements, the print head may need to be raised and lowered during operation to adjust the height and level of the print head. If adjusted manually, the efficiency is very low and the experience of the debugging personnel is very high. It is especially troublesome when switching product models. Using a cylinder as the lifting power for adjustment has low precision and short service life. Utility Model Content

[0005] Preferably, a connecting rod is provided between the mounting bracket and the motor mounting plate.
[0006] Preferably, a position sensor is provided on the connecting rod.
[0007] Preferably, the servo motors at the four corners of the printing head mounting frame act synchronously or individually.
[0008] Preferably, it further comprises a control storage unit, in which the operating parameters of the servo motor corresponding to printing different products are stored.
[0009] The printing head lifting mechanism provided by the present invention has the following beneficial effects: the printing head lifting mechanism of the present invention is used for the lifting and lowering adjustment of the printing head in the screen printing machine, and can adjust the height and level of the printing head. The rising and falling of the printing head can be parameterized and controlled, and the operation is convenient and fast. When printing various models of products, different height parameters of the printing head can be configured through saved parameters and conveniently switched. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 This is a structural schematic diagram of the print head lifting assembly in the print head lifting mechanism of the present invention. DETAILED DESCRIPTION
[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0013] See also Figures 1 to 2 The utility model provides a technical solution: a printing head lifting mechanism, comprising a printing head mounting frame 1, a printing head 2 is mounted on the printing head mounting frame 1, and a printing head lifting assembly 3 is respectively arranged at the bottom of the four corners of the printing head mounting frame 1, and the printing head lifting assembly 3 includes a mounting fixed seat 4, a motor mounting plate 5 is arranged below the mounting fixed seat 4, a servo motor 6 is vertically arranged on the motor mounting plate 5, and a slide rail 7 is vertically arranged between the motor mounting plate 5 and the mounting fixed seat 4, a screw rod 9 is vertically arranged on the working shaft of the servo motor 6 through a coupling 8, a connecting block 10 is sleeved on the screw rod 9, the connecting block 10 is provided with an internal thread, and the internal thread matches the external thread of the screw 9, the connecting block 10 is slidably arranged on the slide rail 7, and a lifting rod 11 is vertically arranged on the connecting block 10, the upper end of the lifting rod 11 extends out of the top of the mounting fixed seat 4, and the upper end of the lifting rod 11 is provided with a lifting fixing head 12, and the lifting fixing head 12 supports the printing head mounting frame 1.
[0014] Preferably, a connecting rod 13 is provided between the mounting base 4 and the motor mounting plate 5 .
[0015] Preferably, a position sensor 14 is provided on the connecting rod 13 , and the position sensor 14 can sense the height change of the connecting block 10 .
[0016] Preferably, the servo motors 6 at the four corners of the print head mounting frame 1 can operate synchronously or separately.
[0017] Preferably, the printer further includes a control storage unit (not shown in the figure), in which the operating parameters of the servo motor corresponding to the printing of different products are stored. The control storage unit is disposed in the printer and is in signal communication with the servo motor. The servo motor operating parameters set for each specification and model of product during printing are stored in the control storage unit. The operating parameters of the servo motor corresponding to products of different specifications and models are stored in the control storage unit. During printing, the operating parameters corresponding to the product can be directly called to achieve parameterized control of the rise and fall of the print head, conveniently switching between products of different specifications, and convenient and quick operation.
[0018] When the print head lifting mechanism of the present invention is working, if the print head is already in a horizontal state, the control storage unit directly controls the servo motor 6 below the four corners of the print head mounting frame 1 to work, and the servo motor 6 drives the screw 9 to rotate, and the connecting block 10 slides up or down on the slide rail 7, and the connecting block 10 drives the lifting rod 11 to rise or fall, thereby causing the lifting and fixing head 12 to rise or fall. When the lifting and fixing head 12 rises, it pushes up the print head mounting frame 1 and the print head 2, so that the height of the print head 2 increases. Conversely, when the lifting and fixing head 12 descends, the print head mounting frame 1 and the print head 2 fall, so that the height of the print head 2 decreases, thereby adjusting the height of the print head.
[0019] When the printing head is not in a horizontal state and is tilted, it is only necessary to control a servo motor 6 that affects the horizontality to return the tilted part of the printing head to the horizontal state, and the adjustment of the printing head is convenient and quick.
[0020] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
