Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, and more specifically, to a multifunctional adjustable screen printing scraper device. Background Art

[0002] Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the screen printing plate with images can pass through the ink, while the mesh holes of the non-image parts cannot pass through the ink.

[0003] During the printing process, due to the gradual reduction of ink content, the images and texts on the later substrates are not clear enough and defective products appear. For this reason, it is necessary to frequently add ink to ensure that the images and texts on the subsequent screen printing plates can be clearly printed. Due to the time of adding ink in the middle, the printing time is prolonged, which further reduces the production efficiency of screen printing. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a multifunctional adjustable silk screen scraper device, which has the advantages of reducing ink, increasing the number of adjustments and improving production efficiency.

The second driving member is installed on the support seat. The linear movement of the second driving member drives the driving rod to move, causing the connecting rod to swing and causing the hinge shaft to rotate. A scraper is connected to one end of the hinge shaft away from the connecting rod.

[0010] Preferably, a pre-tightening mechanism is provided between the scraper and the hinge shaft, and the force of the scraper can be adaptively adjusted through the pre-tightening mechanism.

[0011] Preferably, the pre-tightening mechanism includes a mounting shaft connected to the hinge shaft and a sleeve sleeved on the mounting shaft, the sleeve is fixedly connected to the scraper, and an elastic member is provided between the mounting shaft and the sleeve, and the elasticity of the elastic member is utilized to make the mounting shaft pre-tightened and retracted in the sleeve.

[0012] Preferably, a shell is provided outside the installation shaft, one side of the shell is fixedly connected to the hinge shaft, a cavity connected to the sleeve is provided inside the shell, the elastic member is provided in the cavity, and the installation shaft and the elastic member are provided separately and in parallel.

[0013] To sum up, the utility model has the beneficial effect: during the printing process, the ink content of the screen printing plate is gradually reduced after multiple screen printings. At this time, the angle adjustment mechanism and the height adjustment mechanism are set to promote the change of the scraper angle position and the height position, so as to achieve the adjustment of the scraper corresponding to the screen printing force, so that the screen printing plate can maximize the ink uniformity when printing, and thereby reduce the number of ink increase adjustments, thereby improving the design basis for realizing efficient automated production and accelerating production efficiency.

[0021] A multifunctional adjustment device for screen printing scraper 11, see Figure 1 , comprising a support base 1, a scraper 11 arranged on the support base 1, an angle adjustment mechanism 3 installed on the support base 1 for adjusting the angle of the scraper 11, and a height adjustment mechanism 2 installed on the support base 1 for adjusting the height of the scraper 11;

[0022] By setting the angle adjustment mechanism 3 and the height adjustment mechanism 2, the angle position and the height position of the scraper 11 are changed, so as to adjust the corresponding silk screen printing force of the scraper 11.

[0023] When this embodiment is implemented, since the printing process is a repetitive operation, the ink content of the screen printing plate is gradually reduced after multiple screen printings. At this time, the angle adjustment mechanism 3 and the height adjustment mechanism 2 are set to change the angle position and height position of the scraper 11, so as to adjust the corresponding screen printing force of the scraper 11, so that the screen printing plate can ensure the uniformity of the ink to the greatest extent when printing, and thereby reduce the number of times the ink is increased. Adjustment, improve the design basis for realizing efficient automated production, and accelerate production efficiency.

[0024] Specifically, the height adjustment mechanism 2 includes a telescopic rod 21 fixedly connected to the scraper 11 and a first driving member 22 for driving the telescopic rod 21 to move telescopically, and the first driving member 22 is installed on the support base 1 .

[0025] Regarding the height adjustment of the scraper 11, the telescopic rod 21 is driven to telescope and move by the first driving member 22, that is, the cylinder drives the telescope to telescope. In order to improve the stability of the scraper 11, this embodiment arranges two telescopic rods 21 on the support seat 1, and the two telescopic rods 21 are respectively located at the two ends of the scraper 11. The telescopic rod 21 is driven by the first driving member 22 to move, so as to realize the height adjustment of the scraper 11 moving up and down. In this embodiment, the first driving member 22 is a cylinder or a screw rod connected by a stepping motor, and a screw rod slider is used for linear pushing.

[0026] Specifically, the angle adjustment mechanism 3 includes a hinge shaft 31 hinged to the end of the telescopic rod 21 and a driving component driving the hinge shaft 31 to rotate, and the driving component is installed on the support seat 1.

[0027] Regarding the angle adjustment of the scraper 11, the driving assembly drives the articulated shaft 31 to rotate, and the axial rotation of the articulated shaft 31 is utilized to drive the axial rotation of the scraper 11. In order to avoid mutual interference between the height adjustment and the angle adjustment, the articulated shaft 31 is arranged at the end of the telescopic rod 21, so that the angle adjustment mechanism 3 can move with the up and down movement of the height adjustment mechanism 2.

[0028] Specifically, the driving assembly includes a connecting rod 32 fixedly connected to the hinge shaft 31, a driving rod 33 hinged to one end of the connecting rod 32 away from the hinge shaft 31, and a second driving member 34 for driving the driving rod 33 to move linearly. The second driving member 34 is installed on the support seat 1. The linear movement of the second driving member 34 drives the driving rod 33 to move, so that the connecting rod 32 swings, causing the hinge shaft 31 to rotate. The end of the hinge shaft 31 away from the connecting rod 32 is connected to a scraper 11.

[0029] Since the adjusted angle of the scraper 11 needs to be maintained rigidly and the angle amplitude does not need to be too large, the present embodiment drives the driving rod 33 to move linearly through the second driving member 34, and the driving rod 33 drives the connecting rod 32 to swing, thereby causing the hinge shaft 31 connected to the connecting rod 32 to rotate. In this embodiment, the second driving member 34 is a cylinder or a screw rod connected to a stepping motor, and a screw rod slider is used for linear pushing.

[0030] Specifically, a pre-tightening mechanism 4 is provided between the scraper 11 and the hinge shaft 31 , and the force of the scraper 11 can be adaptively adjusted through the pre-tightening mechanism 4 .

[0031] By setting the angle adjustment mechanism 3 and the height adjustment mechanism 2, the angle position and height position of the scraper 11 are changed. Since the scraper 11 corresponds to the adjustment of the silk screen printing force, in order to avoid hard contact between the scraper 11 and the silk screen printing plate, the pre-tightening mechanism 4 can adaptively adjust the force of the scraper 11 within a certain range to avoid damage to the silk screen printing plate by the scraper 11.

[0032] See also Figure 2 Specifically, the preload mechanism 4 includes a mounting shaft 41 connected to the hinge shaft 31 and a sleeve 42 sleeved on the mounting shaft 41, the sleeve 42 is fixedly connected to the scraper 11, and an elastic member 43 is provided between the mounting shaft 41 and the sleeve 42, and the elasticity of the elastic member 43 is utilized to make the mounting shaft 41 preloaded and retracted in the sleeve 42.

[0033] The scraper 11 and the hinge shaft 31 are pre-connected by using the sleeve between the mounting shaft 41 and the sleeve 42, and the space for the mounting shaft 41 to move between the sleeve 42 is reinforced by using the elastic member 43. The mounting shaft 41 is pre-tightened and retracted in the sleeve 42 by using the elasticity of the elastic member 43, so that the retraction and expansion of the mounting shaft 41 in the sleeve 42 is pre-tightened and resisted. The elasticity of the elastic member 43 allows the scraper 11 to have a buffering force when contacting the screen printing plate. The elastic member 43 in this embodiment is a spring.

[0034] Specifically, a shell 44 is provided outside the installation shaft 41, one side of the shell 44 is fixedly connected to the hinge shaft 31, a cavity 45 connected to the sleeve 42 is provided inside the shell 44, and the elastic member 43 is provided in the cavity 45, so that the installation shaft 41 and the elastic member 43 are arranged separately and in parallel.

[0035] The installation shaft 41 and the elastic member 43 are wrapped by the shell 44 , and the installation space of the elastic member 43 is provided through the cavity 45 of the shell 44 , and the installation shaft 41 and the elastic member 43 are independently and separately arranged in parallel.

[0036] Based on the premise that the moving directions of the first driving member 22 and the second driving member 34 are consistent, a first guide column and a second guide column are respectively arranged on the support seat 1 in the directions of the driving axis of the first driving member 22 and the driving axis of the second driving member 34, and the first guide column is distributed on both sides of the driving axis of the first driving member 22, and the second guide column is distributed on both sides of the driving axis of the first driving member 22.

[0037] Photoelectric sensing switches 6 are provided at the ends of the first guide column and the second guide column, and the travel of the first driving member 22 and the second driving member 34 is controlled by sensing the movement of the driving shaft of the first driving member 22 and the driving shaft of the second driving member 34.
