Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a flat screen printing machine with flattening and absorbing functions, which includes a belt 1 and a frame 2 on the belt 1, wherein the number of the frame 2 can be set according to specific situations.

The method comprises the following specific steps:
referring to fig. 1 and 2, the flattening adsorption device includes an installation shaft seat 4 fixedly installed in front of the guide belt, the installation shaft seat 4 is fixedly installed on the frame 3, a rotating shaft 5 is installed in the installation shaft seat 4, first swing arms 51 are installed at two ends of the rotating shaft 5, and the tail ends of the first swing arms 51 are connected with first adsorption rollers 6; the first swing arm 51 is rotatable about the rotation shaft 5, and the first suction roller 6 swings up and down. The outer periphery of the first suction roller 6 is closely attached to the upper surface of the belt 1 and is obliquely disposed. The first end of the first adsorption roller 6 is fixedly installed on the inner side surface of the first swing arm 51, the second end of the first adsorption roller 6 inclines towards the middle and back relative to the first end, and the first adsorption rollers 6 on the two sides are symmetrically arranged and are not contacted with each other. The first suction roller 6 rotates along with the movement of the cloth 9, and at the same time, as shown by the arrow in fig. 2, the first suction roller 6 provides tension to the cloth 9 to both sides, and the cloth 9 extends to both sides along the arrow in fig. 3, thereby preventing the cloth from being folded. In order to improve the friction force between the cloth 9 and the first adsorption roller 6, a tension spring is erected between the first swing arm 51 and the frame 3, and provides a pressure to the cloth 9 for the first swing arm 51, so as to increase the friction force between the cloth 9 and the first adsorption roller 6. It is worth mentioning that the outer surface of the first adsorption roller 6 has a certain roughness, is made of an electrostatic film layer with adsorption capacity, and can adsorb impurities such as wool on the surface of the fabric. In order to improve the tension provided by the first adsorption roller 6 to the fabric 9, the outer surface of the first adsorption roller 6 is provided with a spiral line.
In order to meet the difficulty of attaching impurities to the fabrics with different materials/thicknesses, compared with the artificial cotton, the terylene is easier to attach the impurities. As shown in fig. 1 and 4, the first swing arm 51 is provided with a first mounting hole set 511, which includes a plurality of first mounting holes; a second mounting hole group 31 is arranged on the frame 3 and comprises a plurality of second mounting holes; one end of the tension spring 8 is arranged in the first mounting hole, and the other end of the tension spring is arranged in the second mounting hole. Different first mounting holes and second mounting holes can be selected to mount the tension springs according to the requirement on cleanliness, the pressure provided by the tension springs is different, so that the pressure between the cloth and the first adsorption roller 6 is different, the friction force between the cloth and the first adsorption roller is influenced, the adsorption effect is finally influenced, and the state shown in figure 4 provides larger friction force than the state shown in figure 1.
Referring to fig. 5, the first suction roller includes a first fixing rod 61, a first sleeve 62 and a first mounting table 63, and a first end of the first fixing rod 61 is mounted on a first end surface of the first mounting table 63; the second end surface of the first mounting platform 63 is an inclined surface 64, and is fixedly connected with the inner side surface of the first swing arm 51 to form a corresponding included angle; the first sleeve 62 is sleeved on the first fixing rod 61. In order to facilitate the installation and the detachment of the first sleeve 62, the first bolt 65 is further included, the first bolt 65 is installed in a threaded hole at the second end of the first fixing rod 61, and the diameter of the tail of the first bolt 65 is larger than that of the first fixing rod 61, so that the first sleeve 62 can be clamped. The end of the first sleeve 62 is provided with a first groove 66 for accommodating the tail of the first bolt 65, so that the first bolt 65 is prevented from scraping cloth.
Since the ends of the two first adsorption rollers 6 are not connected, the middle portion of the cloth 9 is not adsorbed. Referring to fig. 1 and 2, in the present invention, a second swing arm 52 is further disposed on the rotating shaft 5, a second suction roller 7 is connected to a terminal of the second swing arm 52, and an outer periphery of the second suction roller 7 is closely attached to the flat screen printing machine and is located at a middle position of the flat screen printing machine. The suction is performed at a position where the first suction roller 6 cannot suck. Referring to fig. 6, the second suction roller 7 has a structure similar to that of the first suction roller 6. Specifically, the second adsorption roller 7 comprises a second fixing rod 71, a second sleeve 72 and a second mounting table 73, wherein a first end of the second fixing rod 71 is mounted on a first end face of the second mounting table 72; the second end surface of the second mounting table 72 is fixedly connected with the inner side surface of the second swing arm 52; the second sleeve 72 is sleeved on the second fixing rod 71. The second mounting table 73 is a cylinder, the second end of the second fixing rod 71 is also provided with a second bolt 75, and the second end of the second sleeve 72 is provided with a second groove for receiving the second bolt 75.
Referring to fig. 1 and 3, the follow-up fixing device includes a conveyor belt 10 and a pressing plate 11; the two conveying belts 10 are respectively installed on two sides of the screen frame 2, a plurality of pressing plates 11 are arranged on one side of each conveying belt 10 facing the guide belt 1, the pressing plates 11 move along with the conveying belts 10 and the guide belt 1 at the same speed along the same direction, as shown in the figure, the upper surface of the guide belt 1 and the lower surface of the conveying belt 10 move in the same direction at the same speed, and the relative positions of the pressing plates 11 on the lower side and the guide belt 1 are kept unchanged. Along with the movement of the pressing plate 11, the tail part of the pressing plate 11 is periodically pressed on the upper surface of the guide belt 1 to fix the cloth on the guide belt 1, so that the cloth cannot be pulled and deformed due to the movement of the magnetic steel bar in the screen frame 1 when the screen frame works, and the printing quality is ensured. In order to avoid the pressing plate from touching the frame 12 on both sides of the belt 1 during the movement, the middle of the pressing plate 11 on the lower side of the conveyor belt is arched upwards around the frame 12. Meanwhile, in order to fix the net frame 2, two sides of the net frame 2 bypass the conveyer belt 10 through the bent support 21, and the tail part of the support 21 is fixed on the frame 12.
