The protection device is arranged on the surface of the mold. The protection device includes a protection plate and a limiting groove. The limiting groove is opened on the surface of the mold.

[0004] By setting the protection device, the above patent effectively restricts the materials on the surface of the mold when printing the keys, improving the practicability of the device. However, due to the lack of a corresponding clamping mechanism, it is very difficult to replace the printing template. The single use of the printing template may lead to inconsistent printing quality. Especially after using the same template for a long time, the wear of the template may affect the printing effect.

[0005] Therefore, it is necessary to design a printing device for plastic key production. Content of the Utility Model

[0006] In order to overcome the shortcomings of the existing printing device for key production, where the printing template is relatively single, the single use of the template may lead to inconsistent printing quality, and after long-term use of the same template, the wear of the template may affect the printing effect, the technical problem to be solved is: to provide a printing device for plastic key production.

Detailed Description of the Embodiment

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] Embodiment: A printing device for producing plastic buttons, as Figures 1 - 5As shown in the figure, it includes a workbench 1, a controller 2, a first electric slide rail 3, a first electric slider 4, a support plate 5, a clamping member 6, a spring 7, a printing mechanism and a material spraying mechanism. The controller 2 is connected to the right side of the front part of the workbench 1 by bolts. The first electric slide rails 3 are symmetrically distributed on the left and right of the upper part of the workbench 1. Both first electric slide rails 3 are electrically connected to the controller 2. The first electric sliders 4 are slidably connected to both first electric slide rails 3. A support plate 5 is welded between the tops of the first electric sliders 4. The clamping members 6 are slidably connected to the left and right sides of the upper part of the support plate 5. Springs 7 are welded between the mutually remote sides of the two clamping members 6 and the support plate 5. The printing mechanism is arranged at the rear side of the workbench 1, and the material spraying mechanism is arranged above the printing mechanism.

[0024] As Figure 1 and Figure 2 shown in the figure, the material spraying mechanism includes a material feeding barrel 14, a barrel cover 15, a material sprayer 16 and a spray head 17. The material feeding barrel 14 is installed on the upper left side of the support block 9. The barrel cover 15 is threadedly connected to the top of the material feeding barrel 14. The material sprayer 16 is welded to the bottom of the material feeding barrel 14. The material sprayer 16 is electrically connected to the controller 2. Three spray heads 17 are connected to the right side of the material sprayer 16 by bolts.

[0025] When this device is needed to print plastic buttons, first place this device flat on the ground, and then rotate the barrel cover 15 counterclockwise to unscrew the barrel cover 15. The staff can fill the ink into the material feeding barrel 14. When the ink in the material feeding barrel 14 reaches two-thirds of the volume of the material feeding barrel 14, stop filling, and then the staff can tighten the barrel cover 15 clockwise. Then, the staff can manually pull the handle on the outside of the clamping member 6 to compress the spring 7. When the printing template is placed in position, the staff can let go, and the printing template is fixed by the clamping member 6.

[0026] As Figure 1 and Figure 2As shown in the figure, the printing mechanism includes an electric push rod 8, a support block 9, a second electric slide rail 10, a second electric slider 11, a small air cylinder 12, a squeegee 13, a support rod 18, a fixed rod 19 and a screen plate 20. On the lower part of the rear side of the workbench 1, the electric push rods 8 are symmetrically connected by bolts on the left and right. Both electric push rods 8 are electrically connected to the controller 2. A support block 9 is fixedly connected between the upper telescopic rods of the two electric push rods 8. A second electric slide rail 10 is welded on the rear side of the top of the support block 9. The second electric slide rail 10 is electrically connected to the controller 2. A second electric slider 11 is slidably connected to the second electric slide rail 10. Two small air cylinders 12 are symmetrically installed on the front side of the second electric slider 11. A squeegee 13 is connected to the piston rod at the bottom of each of the two small air cylinders 12. The two small air cylinders 12 are electrically connected to the controller 2. The left squeegee 13 is inclined to the left, and the right squeegee 13 is inclined to the right, and the inclination angles are both between 60 and 80 degrees. Support rods 18 are symmetrically distributed on the lower part of the front side of the support block 9. Fixed rods 19 are welded on the side of the two support rods 18 close to each other. A screen plate 20 is slidably connected between the two fixed rods 19. The screen plate 20 is composed of a polyester screen, and anti-leakage borders are provided on the front and rear edges of the screen plate 20.

[0027] After the plastic key to be printed is placed in the printing template by the staff, the staff needs to start the first electric slide rail 3 by operating the controller 2. The first electric slide rail 3 can drive the first electric slider 4 to move backward. The first electric slider 4 then drives the support plate 5, the clamping member 6, the spring 7, the printing template and the plastic key to be printed to move backward together. When the support plate 5, the clamping member 6, the spring 7, the printing template and the plastic key to be printed move to directly below the screen plate 20, the staff can close the first electric slide rail 3 by operating the controller 2 and start the electric push rod 8 at the same time, so that the printing mechanism can move in the vertical direction. When the screen plate 20 moves to 0.5 to 1 millimeter directly above the plastic key to be printed, the staff can stop the movement of the printing mechanism by operating the controller 2.

[0028] When it is necessary to start printing the plastic key, the staff can start the sprayer 16 by operating the controller 2, so that the ink is sprayed onto the surface of the screen plate 20 through the nozzle 17. When a certain amount of ink is sprayed on the surface of the screen plate 20, the staff needs to operate the controller 2 again to start both the second electric slider 11 and the left small air cylinder 12.

[0029] When the second electric slider 11 moves from left to right on the second electric slide rail 10, the piston rod of the small cylinder 12 on the left will drive the squeegee 13 to move downward. At the same time, under the movement of the second electric slider 11, the squeegee 13 is also driven to move to the right. During this process, the ink on the surface of the screen plate 20 can be printed onto the surface of the plastic key to be printed by the left squeegee 13. When the left squeegee 13 is driven by the second electric slider 11 to move to the rightmost side, the printing of the plastic key is completed. The staff needs to close the second electric slide rail 10 and the left small cylinder 12 by operating the controller 2, and then start the first electric slide rail 3, so that the left squeegee 13 is driven by the left small cylinder 12 to reset upward. The first electric slide rail 3 drives the first electric slider 4 to move forward, and the first electric slider 4 then drives the support plate 5, the clamping member 6, the spring 7, the printing template and the printed plastic key to move forward together. The staff can manually take out the printed plastic key and put in a new plastic key to be printed at the same time.

[0030] After the new plastic key to be printed is placed, the staff needs to start the first electric slide rail 3 again by operating the controller 2, so that the new plastic key to be printed moves to directly below the screen plate 20. At this time, the staff only needs to start the second electric slide rail 10 and the two small cylinders 12 by operating the controller 2. Similarly, when the second electric slide rail 10 drives the second electric slider 11 to move from right to left, the piston rod of the small cylinder 12 on the right will drive the squeegee 13 to move downward. During this process, the ink on the surface of the screen plate 20 can be printed onto the surface of the new plastic key to be printed by the right squeegee 13. When the right squeegee 13 is driven by the second electric slider 11 to move to the leftmost side, the printing of the plastic key is completed. Repeat the above steps until the printing work of the plastic key is completed, and the staff can turn off the electrical components of this device.

[0031] As Figure 2 and Figure 5 shown, it also includes a support frame 21 and a recycling box 22. Support frames 21 are welded to the bottom of the front sides of the two fixing rods 19, and a recycling box 22 is placed on the support frames 21. The height of the support frame 21 on the right is lower than that of the support frame 21 on the left, so that the inclination angle of the recycling box 22 is between 2 degrees and 5 degrees.

[0032] As Figure 5 shown, it also includes anti-slip strips 23. A plurality of anti-slip strips 23 are adhesively bonded to the inner walls of the two support frames 21 with glue.

[0033] During the movement of the two squeegees 13, under the action of the anti-leakage frames on the front and rear edges of the screen plate 20, the ink will not easily overflow. If the ink on the surface of the screen plate 20 is excessive and overflows the anti-leakage frames and then overflows the surface of the screen plate 20, the excessive ink will fall into the recovery boxes 22 on the front and rear sides. The staff only needs to regularly remove the recovery boxes 22 from the support frame 21, and then clean or recycle the ink in the recovery boxes 22. At the same time, under the anti-slip function of the anti-slip strips 23, the sliding of the recovery boxes 22 can be effectively avoided.

[0034] When it is necessary to use another printing template to print the plastic keys, the staff can start the first electric slide rail 3 by operating the controller 2. The first electric slide rail 3 drives the first electric slider 4 to move forward. The first electric slider 4 then drives the support plate 5, the clamping member 6, the spring 7 and the printing template to move forward together. Then, turn off the device, and then manually pull the handle outside the clamping member 6 to compress the spring 7, remove the original printing template, and put in a new printing template. When the new printing template is replaced, the staff can let go, so that the new printing template is fixed by the clamping member 6, and then continue to complete the next production work.

[0035] During long-term production work, if the screen plate 20 is damaged and needs to be replaced, the staff can operate the controller 2 to stop the device. Then, the staff needs to manually pull the screen plate 20 forward to make the screen plate 20 leave the two fixed rods 19, and then replace the screen plate 20.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
