A screen printing machine for packaging printing

Abstract

The utility model provides a screen printing machine for packaging printing, which is applied to the technical field of screen printing machines. The device includes a controller to control the operation of an electromagnet, and the electromagnet generates magnetism, thereby generating attraction to a slide bar made of a magnetic core metal material. Under the action of magnetic attraction, the slide bar moves into a cylindrical cavity. When a fixed plate is completely close to an object, the slide bar is subject to resistance from the object and no longer moves into the cylindrical cavity. The controller controls the electromagnet to stop working and lose magnetism, and the slide bar loses its magnetic attraction and recovers under the action of a spring restoring force, thereby driving the slide bar to move to the outside of a placement table to clamp or release the object. In this way, it is possible to achieve clamping or releasing of an object without manually controlling the movement of the fixed plate one by one, thereby improving the working efficiency of the screen printing machine and shortening the working time of the screen printing machine.

[0022] like Figure 1-Figure 3As shown, a screen printer for packaging printing comprises: a workbench 1 and a screen printer body 2 on the top of the workbench 1, a placing table 3 is arranged on the top surface of the workbench 1, a connecting groove 4 is opened on the top surface of the placing table 3, a columnar cavity is opened at the middle end of the bottom surface of the placing table 3, a slide bar 5 is connected in the connecting groove 4, a fixing plate 6 is arranged at one end of the slide bar 5, two adjacent surfaces of the connecting groove 4 and the slide bar 5 are respectively fixedly connected to the two ends of a spring 601, a groove 7 is opened at the middle end of the front side of the workbench 1, an electromagnet 8 is arranged at the middle end of the groove 7, and the output end of the electromagnet 8 is located at At the top of the columnar cavity, four connecting grooves 4 are arranged in a circular array on the top surface of the placing platform 3, and each connecting groove 4 is perpendicular to each other. A circular hole is arranged on one side of the connecting groove 4 close to the middle end of the placing platform 3, a sliding rod 5 is slidably connected in the connecting groove 4, and one end of the sliding rod 5 is slidably connected to the circular hole, a fixing plate 6 is welded to the end of the sliding rod 5 away from the circular hole, and the number of the sliding rod 5 and the fixing plate 6 is consistent with the number of the connecting grooves 4, an electromagnet 8 is fixedly installed at the middle end of the inner wall of the bottom surface of the groove 7, and the outer peripheral surface of the output end of the electromagnet 8 is adjacent to one end of the sliding rod 5, and the working A controller 9 is fixedly installed on one side of the middle end of the front side of the workbench 1, and the controller 9 is electrically connected to the electromagnet 8. When the spring 601 is in the shortest stroke, one end of the slide bar 5 is retracted into the columnar cavity, and the slide bar 5 is a rod-shaped structure made of magnetic metal material. When it is necessary to screen print an object, the object is placed on the middle end of the top surface of the placement table 3, and the electromagnet 8 is controlled by the controller 9 to work. The electromagnet 8 generates magnetism, thereby generating attraction to the slide bar 5 made of magnetic metal material. Under the action of magnetic attraction, the slide bar 5 moves into the columnar cavity. When the fixed plate 6 is completely close to the object, the slide bar 5 is resisted by the object and no longer moves into the cylindrical cavity, thereby clamping the object. When the screen printing of the object is completed, the controller 9 controls the electromagnet 8 to stop working and lose its magnetism, and the slide bar 5 loses its magnetic attraction and recovers under the restoring force of the spring 601, thereby driving the slide bar 5 to move to the outside of the placement table 3, thereby releasing the object. There is no need for the operator to manually control the fixed plate 6 to clamp the object. The screen printing machine body 2 is located above the placement table 3, and the screen printing machine body 2 is used to perform screen printing on the object.

[0023] The electromagnet 8 is controlled by the controller 9 to work, and the electromagnet 8 generates magnetism, thereby generating attraction to the slide bar 5 made of magnetic metal material. Under the action of magnetic attraction, the slide bar 5 moves into the columnar cavity. When the fixed plate 6 is completely close to the object, the slide bar 5 is resisted by the object and no longer moves into the columnar cavity. The controller 9 controls the electromagnet 8 to stop working and lose magnetism. The slide bar 5 loses its magnetic attraction and recovers under the restoring force of the spring 601, thereby driving the slide bar 5 to move toward the outside of the placement table 3 to clamp or release the object. There is no need to manually control the movement of the fixed plate 6 one by one to clamp or release the object, thereby improving the working efficiency of the screen printing machine and shortening the working time of the screen printing machine.

[0024] Working principle: When in use, the object to be screen-printed is placed on the top surface of the placement table 3, and the operator starts the electromagnet 8 by controlling the controller 9. The electromagnet 8 generates magnetism when it is started, which generates attraction to the slide bar 5. The slide bar 5 moves toward the columnar cavity, thereby driving the fixed plate 6 to clamp the object. When the object is clamped, the screen printing machine body performs screen printing on its surface. After printing is completed, the operator controls the controller 9 to turn off the electromagnet 8, and the electromagnet 8 loses its magnetism. The spring 6 recovers under the action of the restoring force. The slide bar 5 moves toward the outside of the placement table 3 under the action of the restoring force of the spring 6, thereby loosening the object, taking out the object after screen printing, and re-putting a new object.

[0025] The screen printing machine body, workbench, slide bar, electromagnet and spring are all universal standard parts or known through conventional experimental methods, so no further records are made here.

[0026] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
