Description

Technical Field

[0001] This utility model relates to the field of multi-color pad printing devices, specifically to a multi-color pad printing device for toy manufacturing. Background Technology

[0002] Currently, toy plastic parts manufacturers typically need to pad print various patterns or text onto the surface of small plastic parts during production. This requires the use of multi-color pad printing equipment. In the pad printing process, a printing template, usually a silicone rubber stamp or roller, is first prepared. This template has the pattern or text to be printed on it. Then, a suitable ink is selected. During operation, the printing template picks up the ink, and the printing head transfers the pattern onto the elastic medium, ultimately transferring it onto the product.

[0003] In the production of plastic toys, due to the irregular shapes of many toys, in the process of multi-color pad printing, incomplete printing can easily occur in a single printing cycle due to angle issues. Currently, this is done manually, waiting for the first curing before flipping the product. However, manual operation may make it difficult to ensure precise alignment of the front and back sides of the product. Even if visual alignment is achieved, the instability of manual operation makes it difficult to achieve the same mechanical precision. This may result in inaccurate positioning of patterns or text on the front and back sides.

[0004] Therefore, it is necessary to invent a multi-color pad printing device for toy manufacturing to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-color pad printing device for toy manufacturing, so as to solve the problem mentioned in the background art that the single pad printing is prone to incomplete printing due to angle issues.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5 The multi-color pad printing device for toy manufacturing shown includes a mounting frame 1. A first adjustable seat 2 is fixedly connected to the lower part of one side of the mounting frame 1. A support plate 3 is slidably connected to the top of the first adjustable seat 2. Fixed frames 4 are rotatably connected to both sides of the top of the support plate 3. First clamping strips 5 are fixedly connected to the front and rear of both sides of the fixed frames 4. A limiting groove 6 is fixedly connected to the middle of the inner side of the fixed frame 4. A driving mechanism 7 is provided inside the limiting groove 6. A stepper motor 8 is fixedly connected to one side of the support plate 3. The top of the support plate 3... A series of synchronous electric cylinders 9 arranged in a rectangular row are fixedly connected. A rectangular positioning block 10 is fixedly connected to the telescopic end of the synchronous electric cylinder 9. A second electric cylinder 11 is fixedly connected to the upper part of one side of the mounting frame 1. A second adjustable seat 12 is fixedly connected to the telescopic end of the second electric cylinder 11. A third electric cylinder 13 is fixedly connected to the top of the second adjustable seat 12. A mounting socket 14 is fixedly connected to the telescopic end of the third electric cylinder 13. An angle adjustment mechanism 15 is fixedly connected to the bottom of the mounting socket 14. An ink supply mechanism 16 is fixedly connected to the middle of one side of the mounting frame 1.

[0025] The drive mechanism 7 includes a synchronous clamping bar 71, a rotating shaft 72 rotatably connected to the center of the inner cavity of the limiting groove 6, a gear 73 fixedly connected to the surface of the rotating shaft 72, a synchronous motor 74 fixedly connected to one side of the limiting groove 6, and one end of the rotating shaft 72 fixedly connected to the output end of the synchronous motor 74.

[0026] Specifically, in use, the synchronous clamping bar 71 has gear teeth 73 that mesh with the gear 73 on the side closest to the gear 73. Since both sides of the synchronous clamping bar 71 mesh with the gear 73, the synchronous motor 74 serves as the drive source for the overall drive mechanism 7, i.e., the rotating shaft 72. By controlling the rotation direction and angle of the rotating shaft 72, the gear 73 synchronously drives the synchronous clamping bars 71 on both sides to move horizontally towards each other during rotation. The first clamping bar 5, which is fixedly installed inside the fixed frame 4, cooperates with the synchronous clamping bar 71 to clamp and fix the plastic toy between the clamping bars. At the same time, a continuous trapezoidal rubber strip is provided on the side of the synchronous clamping bar 71 corresponding to the first clamping bar 5 to increase the friction between them during the clamping process and prevent the toy from falling off during the clamping and fixing process.

[0027] The angle adjustment mechanism 15 includes a vertical plate 151, an adjustment plate 152 is hinged to one end of the vertical plate 151, a fourth electric cylinder 153 is hinged to one side of the top of the adjustment plate 152, and the telescopic end of the fourth electric cylinder 153 is hinged to one side of the vertical plate 151.

[0028] Specifically, in use, the fourth electric cylinder 153 is used as the driving source. The connection between the adjusting plate 152 and the vertical plate 151 is used as the axis. By pushing the end of the adjusting plate 152 away from the vertical plate 151 to make an up-and-down arc movement, the printing angle of the printing component at the bottom of the adjusting plate 152 on the toy is controlled. This avoids the problem that the printing head 18 cannot print the pattern completely on the surface of the toy after contacting irregular toy parts during the pressing process.

[0029] The ink supply mechanism 16 includes a placement socket 161, with two pattern boxes 162 slidably inserted into the upper part of the placement socket 161, and a bidirectional scraper 163 hinged to the front of the two pattern boxes 162.

[0030] Specifically, during use, the placement of the socket 161 allows the top pattern box 162 to be quickly removed by pulling it horizontally after prolonged use. It is then fixed by rotating the bolts on its front. The two pattern boxes 162 make it convenient for users to apply different printing inks to the printing head 18. The bidirectional squeegee 163 can effectively clean excess ink from the contact surface between the printing head 18 and the ink, preventing the problem of ink dripping due to excessive ink being picked up at once.

[0031] The bottom of the adjusting plate 152 is fixedly connected to a printing sleeve 17, and the printing sleeve 17 is provided with a printing head 18 on the inner side.

[0032] Specifically, during use, the printing sleeve 17 can limit the installation of the printing head 18.

[0033] Two first limiting rods 19 are fixedly connected to the upper part of one side of the mounting bracket 1, and the outer walls of the two first limiting rods 19 are slidably sleeved with the inner side of the second adjustable seat 12.

[0034] Specifically, in use, the horizontal movement path of the second adjustable seat 12 is limited by the setting of the first limiting rod 19, so as to avoid the second adjustable seat 12 from moving off course during the pushing process of the second electric cylinder 11, thereby improving the smoothness of the movement of the second adjustable seat 12.

[0035] The top two sides of the mounting socket 14 are fixedly connected with the second limiting rod 20, and the surface of the second limiting rod 20 is slidably inserted into the inner side of the second adjustable seat 12.

[0036] Specifically, during use, the second limiting rod 20 ensures that the third electric cylinder 13 is always vertically limited by the second limiting rod 20 during the process of pushing the installation socket 14, thereby fixing the movement path of the installation socket 14.

[0037] Refer to the instruction manual appendix Figure 1-5 Working principle: During the use of the device, the synchronous motor 74 drives the rotating shaft 72 and gear 73 to rotate, causing the gear 73 to push the synchronous clamping bars 71 on both sides to move horizontally in the opposite direction of the first clamping bar 5, thus creating clamping space for the toy to be processed. After the toy is fixed inside the fixed frame 4, the corresponding pigment is added to the pattern box 162. The second electric cylinder 11 is then controlled to push the second adjustable seat 12 horizontally to the top of the pattern box 162, and the third electric cylinder 13 is controlled to vertically push the bottom mounting socket 14 vertically downward until the bottom side of the printing head 18 contacts the pigment, causing it to be removed from the pattern box 162. The second electric cylinder 11 is then controlled to push the mounting socket 14 vertically downward until the bottom side of the printing head 18 contacts the pigment, thus removing it from the pattern box 162. The socket 14 is positioned above the top of the toy to be transferred. Finally, the angle adjustment mechanism 15 controls the downward printing angle of the printing head 18, causing the third electric cylinder 13 to push the printing head 18 downward to perform the transfer printing operation on the toy. Then, the synchronous electric cylinder 9 is controlled to drive the rectangular positioning block 10 downward, causing the rectangular positioning block 10 to lose its horizontal limit on the fixed frame 4. The toy is flipped over by rotating the fixed frame 4 through the stepper motor 8. At the same time, the synchronous electric cylinder 9 is controlled to push the rectangular positioning block 10 upward again to support and position the fixed frame 4. Then, the untransfer-printed area at the bottom of the toy is flipped to the top. The above steps are repeated to perform the transfer printing operation on both sides of the toy, thus completing the transfer printing work on the toy.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
