[0032] Embodiment 1:

[0033] In order to solve the problem that the existing screen printers generally fix the plastic parts manually and print them, this operation method is prone to plastic parts deviation, affecting the use. Therefore, the following solution is disclosed. For details, please refer to Figure 2-Figure 3The interior of the pull-out plate 11 is fixedly connected with a first motor 121, and the first motor 121 is provided with two groups. The output end of the first motor 121 is fixedly connected with an active roller 122. The interior of the pull-out plate 11 is also rotatably connected with a transmission roller 123. The outer sides of the active roller 122 and the transmission roller 123 are sleeved with belts. The left and right ends of the transmission roller 123 are fixedly connected with positive and negative threaded rods 124. A slide groove 125 is provided on the top of the placement plate 12. The left and right sides of the positive and negative threaded rods 124 are threadedly connected with a fixed block 126. The other end of the fixed block 126 is slidably connected to the inner side of the slide groove 125. At this time, the pull-out plate 11 is pulled out from the inside of the retractable opening 2, and the plastic parts to be processed are placed on the placement plate 12. At this time, the first motor 121 is started. The first motor 121 drives the active roller 122 to rotate, and the active roller 122 can rotate the transmission roller 123 through the belt. At this time, the transmission roller 123 rotates the two groups of positive and negative screw rods 124, so that the four groups of fixed blocks 126 slide inside the slide groove 125, so as to clamp the plastic parts placed on the placement plate 12 to prevent them from shifting. When the pull-out plate 11 is pushed to the inside of the retractable opening 2, the control mechanism 21 can be started at this time, and the control mechanism 21 takes effect on the screen printing mechanism 212. At this time, the electric push rod 211 is started, and the screen printing mechanism 212 is pressed down, so as to perform screen printing on the plastic parts on the placement plate 12, thereby preventing the plastic parts from shifting during screen printing and improving the working effect.

[0034] Embodiment 2:

[0035] In order to solve the problem that most existing screen printers dry plastic parts by air cooling after work, which is prone to slow drying efficiency and thus affects the overall work process, the following solution is disclosed. Please refer to the details. Figure 1 , Figure 3 , Figure 4 and Figure 5The output end of the second motor 13 is fixedly connected to a bevel gear 131, one side of the bevel gear 131 is fixedly connected to a reciprocating screw rod 132, the outer side of the reciprocating screw rod 132 is threadedly connected to a fan module 133, the fan module 133 is slidably connected to the inside of the screen printing machine body 1, the other end of the contact block 14 is fixedly connected to a reset spring 141, the other end of the reset spring 141 is fixedly connected to the inside of the screen printing machine body 1, the other side of the contact block 14 is fixedly connected to a card block 142, one side of the bevel gear 131 is meshedly connected to a bevel gear 2 143, one side of the bevel gear 2 143 is fixedly connected to a protrusion 144, the protrusion 144 is provided with a card slot 145, the card slot 145 matches the card block 142, when the screen printing is completed, the second motor 13 and the fan module 133 can be started, the second motor The machine 13 drives the bevel gear 131 to rotate, thereby rotating the reciprocating screw rod 132. The reciprocating screw rod 132 can make the fan module 133 reciprocate inside the screen printing machine body 1, thereby drying the plastic parts on the multiple groups of placement plates 12, and the drying efficiency can be improved at this time. When the pull-out plate 11 is pulled out to the outside of the receiving opening 2, the contact block 14 automatically moves under the action of the reset spring 141, thereby making the clamping block 142 clamped to the inside of the clamping groove 145 and fixing the protrusion 144. Due to the meshing connection between the bevel gear 2 143 and the bevel gear 1 131, the bevel gear 1 131 cannot rotate, thereby avoiding the situation that the processing is completed while the second motor 13 is still started, achieving the effect of drying the workpiece more efficiently and improving the work efficiency.
