Problems solved by technology

[0005] Because this kind of screen printing machine controls the operation of the screen printing machine by multiple dispersed transmission mechanisms, its production efficiency is low, and it is difficult to grasp the time difference between the successive actions of the control transmission mechanism, which increases the difficulty of manufacturing and increases the cost of manufacturing.
And each independent transmission mechanism needs an independent power source. If you want to use the cylinder, you need to be equipped with auxiliary accessories such as an air pump or an air storage tank, which makes the structure of the entire screen printing machine complicated.
In addition, the needle cylinder is positioned by the copper wheel. During the printing process, the needle cylinder rolls along the copper wheel, which is easy to damage the printed pattern, and there are burrs on the surface of the copper wheel. Using the copper wheel to support it is easy to cut the screen

Embodiment 1

[0033] like figure 1 As shown, the screen printing device is applied to an automatic circular screen printing machine. The automatic circular screen printing machine includes a feeding mechanism 1a, a feeding mechanism 1b, a feeding mechanism 1c, a printing mechanism 1d, a drying device 1e and a discharging device 1f. The invention relates to a material ejecting mechanism 1c and a printing mechanism 1d in an automatic circular screen printing machine, which are used to support workpieces being conveyed and complete printing operations.

[0034] like figure 2 , image 3 and Figure 4 As shown, the screen printing device is arranged on the frame 1, and includes a conveyor chain 41 for transferring workpieces. There are two conveyor chains 41 and they move synchronously. It is placed between the corresponding brackets 42 on the two conveyor chains 41 under the action of the feeding mechanism 1a. Above the conveyor chain 41 is provided a screen printing ink cartridge 5 for pr...

Embodiment 2

[0044] like Figure 5 As shown, the structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that the clamping mechanism 2 of this embodiment includes a motor 21, a drive shaft 23 connected to the output shaft of the motor 21, a fixed connection Two side-turning cams 28 on the drive shaft 23 and two rockers 25 hinged on both sides of the frame 1, the outer sides of the two side-turning cams 28 have an active surface 28a with a height difference along their axial direction One end of the rocker 25 is in contact with the action surface 28a of the corresponding side-rotating cam 28 through the roller 25a, and the other end is connected with a fixed seat 26, and the above-mentioned two support members 22 are respectively arranged on the corresponding fixed seat 26. The motor 21 can drive the transmission shaft 23 to rotate through the cooperative relationship such as a pulley, a worm gear, or a bevel gear. When the transmission shaft...

Abstract

The invention provides a screen printing device in an automatic round-surface screen printing machine, belonging to the field of mechanical technology and solving the problems of complex structure and low production efficiency of the traditional screen printing device. The screen printing device in the automatic round-surface screen printing machine is arranged on a stand and comprises a transmission chain for transmitting a workpiece, wherein the transmission chain is fixedly connected with a support for holding the workpiece, a screen printing ink box for printing the workpiece is arranged above the transmission chain, the stand is provided with a translation mechanism for controlling the screen printing ink box to reciprocate along a horizontal plane, the stand is provided with a jacking mechanism capable of jacking the workpiece on the support onto the screen printing ink box, two sides of the stand are further provided with a clamping mechanism with two supporting members, the supporting members can rotate by taking the respective axis as a center, and when the workpiece is jacked up by the jacking mechanism, the two supporting members can jack and press the two ends of the workpiece respectively. The screen printing device in the automatic round-surface screen printing machine has the advantages of good printing quality, high efficiency, high printing speed, low fault rate and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a novel fast silk screen printing device, in particular to a screen printing device in an automatic circular screen printing machine. Background technique [0002] As a kind of printing equipment, screen printing machine has been widely used in various medical applications such as the printing of surface graphics on syringes. The circular screen printing machine is to print on the cylindrical surface of an item with a cylindrical surface. [0003] The existing syringe scale line screen printing machine is a kind of circular screen printing machine. The syringe is conveyed to the bottom of the silk screen ink cartridge through the transmission chain, and then driven by the transmission mechanism to lift the syringe to the silk screen ink cartridge. The silk screen ink cartridge Driven by the transmission mechanism, it moves left and right, and the scraper moves downward to scrape...
