Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, a full-automatic screen printer convenient for printing plate replacement comprises a printing plate 1, two pin shafts 101 are welded on two sides of the printing plate 1 respectively, the pin shafts 101 are arranged in two numbers, the distance between the two pin shafts 101 is the same as the relative distance between the two chutes 6, so that the printing plate can slide into the chutes 6 simultaneously, connecting rods 2 are arranged on two horizontal sides of the printing plate 1, mounting blocks 5 are embedded in the inner sides of the two connecting rods 2 in a sliding manner, the mounting blocks 5 are arranged in two numbers, the chutes 6 are arranged on the inner sides of the four mounting blocks 5, limiting pieces 8 are arranged at the end positions of the chutes 6, and the limiting pieces 8 are elastically connected with the mounting blocks 5 through extrusion springs 9;

the limiting sheet 8 is of a two-section structure and comprises a bearing portion 801 and a coating portion 802, the bearing portion 801 and the coating portion 802 are both of arc structures and are arranged tangentially, the arc directions of the bearing portion 801 and the coating portion 802 are opposite, and when the pin shaft 101 is not arranged below, the top end of the bearing portion 801 and the central line of the chute 6 are arranged tangentially, so that good contact between the bearing portion 801 and the pin shaft 101 is guaranteed.

Specifically, as shown in fig. 1 and fig. 2, 6 side views of spout are the structure of falling the U-shaped, and the one end of spout 6 runs through installation piece 5 and outside intercommunication, the other end is the arc structure with round pin axle 101 clearance fit, clearance fit between spout 6 and the round pin axle 101, accepting portion 801 diameter is less than cladding portion 802, and cladding portion 802 internal diameter is the same with round pin axle 101 external diameter, the welding of top central point department of cladding portion 802 has driving lever 7, and driving lever 7 runs through installation piece 5 and extends to installation piece 5 upper end, driving lever 7's top is provided with the stopper, restrict driving lever 7's vertical height, prevent that accepting portion 801's height from crossing lowly, thereby influence round pin axle 101 installation, and the sliding fit between driving lever 7 and the installation piece 5, driving lever 7 overlaps with extrusion spring 9 and establishes.

Specifically, as shown in fig. 1-4, four corners of the mounting block 5 are provided with fixed blocks 3 outside, and the fixed blocks 3 are welded to the connecting rod 2, and two fixed blocks 3 located at the same vertical side are connected with an adjusting screw rod 4 in a rotating manner, the adjusting screw rod 4 axially passes through a limiting disc with the fixed blocks 3, the axial direction is limited, the radial direction is rotated and set, the outside cover in top of the adjusting screw rod 4 is provided with an index plate 10, the index plate 10 is welded to the upper end face of the fixed blocks 3, the top of the adjusting screw rod 4 is provided with a groove for observing the reading of the index plate 10, and the adjustment is facilitated, the adjusting screw rod 4 is connected with a threaded sleeve 11 through threads, and the threaded sleeve 11.

The working principle is as follows: when the printing plate 1 is installed, the pin shaft 101 of the printing plate 1 slides inwards from the opening end of the chute 6, when the pin shaft 101 slides to the tail end of the horizontal end, the pin shaft contacts with the tilting section of the limiting sheet 8, when the pin shaft 101 continues to slide towards the inside of the chute 6, the limiting sheet 8 is pushed upwards and finally moves into the placing groove at the tail end of the chute 6, and under the action of the extrusion spring 9, the limiting sheet 8 is always kept above the pin shaft 101 and applies downward force, so that the stable placement of the printing plate 1 is kept; when the printing plate is dismounted, the whole printing plate 1 is lifted upwards, the pin shaft 101 pushes the limiting piece 8 to move upwards, and when the printing plate moves to the horizontal section of the sliding groove 6, the printing plate can slide outwards to finish dismounting; after printing plate 1 accomplished the installation, new printing plate 1 probably and printing machine brush and have certain clearance between the board, at this moment, the adjusting screw 4 of the same 5 both sides of installation piece of syntropy rotation simultaneously, because adjusting screw 4 axial position is fixed on fixed block 3, thereby the threaded sleeve pipe 11 of transmission threaded connection on adjusting screw 4 carries out axial position's regulation, thereby transmission installation piece 5 reciprocates the position, adjust the interval between printing plate 1 and the brush board, because relative independence between four fixed blocks 3, thereby can realize independent regulation to four corners of printing plate 1, increase the flexibility of device.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
