Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to an automated screen printer. Background Technology

[0002] A screen printing machine is a machine that uses a screen printing plate to print. Screen printing belongs to stencil printing. During printing, ink is transferred to the substrate through the mesh of the image area by the pressure of a squeegee, forming an image that is identical to the original.

[0003] For example, the fully automatic screen printing device disclosed in Chinese patent application CN201821428238.4 includes a screen printing plate, a first squeegee, a second squeegee, a printing table, a printing fixing plate, a first roller, a second roller, a motor, a first cylinder, a second cylinder, and a third cylinder. Mounting plates are provided on both the first and second fixing hole groups. Two screws are fixed to the bottom of the mounting plate, passing through through holes and secured with nuts. The mounting plates are fixed above the first and second fixing hole groups, respectively. This device has the following technical problems:

[0004] The printing plate has mounting plates on both sides for limiting the substrate, and each mounting plate has two screws at the bottom. This means that eight nuts need to be tightened when printing on substrates of different sizes. It can be seen that the adjustment of the mounting plates is quite cumbersome when limiting substrates of different sizes. Utility Model Content

[0005] To address the problem of cumbersome adjustment operations of the mounting plate mentioned in the background section, this utility model provides the following technical solution:

[0007] A printing fixing plate is installed on the upper end of the printing table, a screen printing plate is installed on the upper end of the printing fixing plate, and a printing part for printing on the substrate is installed on the upper end of the printing fixing plate.

[0008] Two limiting components for limiting the substrate are respectively installed on the left and right sides of the printing fixing plate. An adjustment component for controlling the two limiting components to move in opposite directions is installed at the lower end of the limiting components. Scale marks are provided at the left and right ends of the printing fixing plate to facilitate the adjustment of the distance between the two limiting components.

[0009] Furthermore, the limiting component includes a limiting plate for limiting the printing substrate, and a lead screw nut is installed at the lower end of the limiting plate.

[0010] Furthermore, the adjustment assembly includes a reciprocating screw two for cooperating with the control limit plate to move back and forth, and the helical grooves at the front and rear ends of the reciprocating screw two have opposite rotation directions. A handwheel for rotating the reciprocating screw two is installed at the front end of the reciprocating screw two.

[0011] Furthermore, a lead screw nut is installed at the lower rear end of the printed part, and a fixing frame for limiting the lead screw nut is installed at the rear end of the printing fixing plate. A guide rod is installed in the middle of the fixing frame, and a reciprocating lead screw for cooperating with the lead screw nut to control the left and right movement of the printed part is installed in the middle of the fixing frame. A motor is installed at the right end of the reciprocating lead screw.

[0012] Furthermore, a second fixing frame is installed at the front end of the printing fixing plate, a rotating rod is installed in the middle of the second fixing frame, a bevel gear is installed at both the left and right ends of the rotating rod, and a second motor is installed at the right end of the rotating rod.

[0013] Furthermore, rollers are installed at both ends of the printing plate, a rotating shaft is installed in the middle of the rollers, bearing seats for limiting the rotation shaft are installed at both ends of the rotating shaft, and a second bevel gear for meshing with the first bevel gear is installed at the front end of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When adjusting the distance between the two limiting plates according to the different sizes of the substrate, this utility model only requires rotating the handwheel. The reciprocating screw two, together with the screw nut two, can adjust the distance between the two limiting plates. In addition, with the setting of the scale, the distance between the two limiting plates can be adjusted quickly. When the motor two starts, it synchronously drives the rotating rod to rotate. The cooperation of bevel gear one and bevel gear two makes the two rotating shafts drive the two rollers to rotate synchronously. Therefore, the two rollers rotate at the same speed, making the movement of the substrate more stable. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0022] Please see Figures 1-3 This utility model provides an automated screen printing machine, including a printing table 100, a printing fixing plate 110 installed on the upper end of the printing table 100, and a screen printing plate 30 installed in the middle of the upper end of the printing fixing plate 110.

[0023] The upper end of the printing plate 110 is equipped with a printing element 140 for printing on the substrate. The printing element 140 is prior art. The printing element 140 includes an L-shaped support frame, and the lower end of the L-shaped support frame is provided with two squeegees. Each squeegee is provided with an electric push rod to control the squeegee to move downward to scrape the ink on the screen printing plate 30.

[0024] A lead screw nut 141 is fixedly installed at the lower rear end of the printed part 140. A fixing bracket 150 for limiting the lead screw nut 141 is fixedly installed at the rear end of the printing fixing plate 110 by bolts. A guide rod 152 is fixedly installed in the middle of the fixing bracket 150. The guide rod 152 is used to guide the lead screw nut 141 so that the lead screw nut 141 can only drive the printed part 140 to move left and right. A reciprocating screw 151 is installed in the middle of the fixed frame 150 to control the left and right movement of the printing part 140 in conjunction with the screw nut 141. A motor 153 is installed at the right end of the reciprocating screw 151. After the motor 153 is started, it drives the reciprocating screw 151 to rotate, so that the reciprocating screw 151, in conjunction with the screw nut 141, drives the printing part 140 to move left and right. This allows the two scrapers at the lower end of the printing part 140 to scrape the ink on the screen printing plate 30. During the movement, the ink is squeezed from the mesh of the image area onto the substrate by the scrapers.

[0025] Two limiting components 120 for limiting the printing substrate are respectively installed on the left and right sides of the printing fixing plate 110. The setting of multiple limiting components 120 facilitates the limiting of printing substrates of different sizes. The limiting component 120 includes a limiting plate 121 for limiting the printing substrate. A screw nut 122 is fixedly installed at the lower end of the limiting plate 121. The screw nut 122 slides inside the printing fixing plate 110, and the printing fixing plate 110 has a groove inside for the screw nut 122 to slide back and forth.

[0026] The lower end of the limiting assembly 120 is equipped with an adjusting assembly 130 for controlling the two limiting assemblies 120 to move in opposite directions. The adjusting assembly 130 includes a reciprocating screw 131 that works with a screw nut 122 to control the back-and-forth movement of the limiting plate 121. The spiral grooves at the front and rear ends of the reciprocating screw 131 rotate in opposite directions, so that the two limiting assemblies 120 move in opposite directions. A handwheel 132 for rotating the reciprocating screw 131 is installed at the front end of the reciprocating screw 131. The left and right ends of the printing fixing plate 110 are provided with scale marks 10 to facilitate the adjustment of the distance between the two limiting assemblies 120. When limiting substrates of different sizes, the distance between the screw nuts 122 at the front and rear ends of the reciprocating screw 131 is adjusted by rotating the handwheel 132. The distance between the two limiting plates 121 can be quickly adjusted according to the size of the substrate by setting the scale marks 10.

[0027] A second mounting bracket 160 is bolted to the front end of the printing plate 110. A rotating rod 161 is mounted in the middle of the mounting bracket 160. A bevel gear 162 is fixedly mounted at both ends of the rotating rod 161, and a second motor 163 is mounted at the right end of the rotating rod 161. Rollers 20 are movably mounted at both ends of the printing plate 110. A rotating shaft 22 is fixedly mounted in the middle of the rollers 20. Bearing seats 21 for limiting the rotation shaft 22 are mounted at both ends of the rotating shaft 22. A second bevel gear 23 for meshing with the first bevel gear 162 is fixedly mounted at the front end of the rotating shaft 22.

[0028] When motor 163 starts, it synchronously drives the rotating rod 161 to rotate. The cooperation of bevel gear 162 and bevel gear 23 causes the two rotating shafts 22 to drive the two rollers 20 to rotate synchronously. Therefore, the two rollers 20 rotate at the same speed, making the movement of the printing substrate more stable.

[0029] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
