Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, and particularly relates to a screen printing machine. Background Art

[0002] The full name of the screen printing machine is "screen printing press". It is a machine for printing words and images, a machine or device for producing printed matter, and prints by using the basic principle that the mesh holes in the graphic part of the screen printing plate can pass through the ink, while the mesh holes in the non-graphic part cannot pass through the ink. When using the screen printing machine, it is necessary to adjust the alignment between the object to be screen-printed and the screen printing mesh. When screen-printing different colors on the same object to be screen-printed, it is also necessary to adjust the screen printing platform for alignment. The adjustment of the screen printing platform includes the X-axis direction and the Y-axis direction. In the prior art, the adjustment knob in the X-axis direction is arranged on one side of the screen printing platform adjustment structure, and the adjustment knob in the Y-axis direction is arranged on the other side of the screen printing platform adjustment mechanism. When the screen-printed items are bags, clothes, etc., these items need to be put on the screen printing platform and the screen printing platform adjustment structure. Three sides of the screen printing platform adjustment structure will be blocked by the bag, and one side will not be blocked by the bag. Because adjustment knobs are arranged on both sides of the screen printing platform adjustment structure, one of the adjustment knobs (the adjustment knob in the X-axis direction or the adjustment knob in the Y-axis direction) will be blocked by the bag, affecting the adjustment function of the screen printing platform adjustment structure and making it impossible to normally adjust the position of the screen printing platform.

[0034] As Figures 1 to 3 shown, in an embodiment, a silk screen printing machine includes a silk screen printing platform 100, a supporting component 200, a first adjusting mechanism 300, and a second adjusting mechanism 400. The silk screen printing platform 100 is used for placing the object to be silk screen printed. The silk screen printing platform 100 is movably arranged on the upper surface of the supporting component 200, and the first adjusting mechanism 300 is arranged below the supporting component 200. And the first adjusting mechanism 300 is connected to the silk screen printing platform 100. The first adjusting mechanism 300 has a first driving member 310, and the first driving member 310 can drive the first adjusting mechanism 300 to adjust the silk screen printing platform 100 to move relative to the supporting component 200 along a first direction. The second adjusting mechanism 400 is arranged below the supporting component 200, and the second adjusting mechanism 400 is connected to the silk screen printing platform 100. The second adjusting mechanism 400 has a second driving member 410, and the second driving member 410 can drive the second adjusting mechanism 400 to adjust the silk screen printing platform 100 to move relative to the supporting component 200 along a second direction. The second direction is perpendicular to the first direction, and both the first driving member 310 and the second driving member 410 are arranged on the same side surface of the supporting component 200. Specifically, the Y-axis direction is the first direction, and the X-axis direction is the second direction. Both the silk screen printing platform 100 and the supporting component 200 are rectangular plate-like structures. As Figure 2 shown, the first driving member 310 and the second driving member 410 can be, but are not limited to, knobs.

[0035] Specifically, in this embodiment, the supporting component 200 may include a plate body, and then the silk screen printing platform 100 can be movably arranged on the upper surface of the plate body of the supporting component 200. The first adjusting mechanism 300 and the second adjusting mechanism 400 can be directly arranged on the lower surface of the supporting component 200, which is convenient for the assembly and stable driving of the first adjusting mechanism 300 and the second adjusting mechanism 400.

[0036] In other embodiments, the first adjusting mechanism 300 and the second adjusting structure 400 may also be located below the supporting assembly 200. The first adjusting mechanism 300 and the second adjusting structure 400 may be arranged in a spatially staggered manner. The first adjusting mechanism 300 and the second adjusting structure 400 can also achieve the function of adjusting the position of the screen printing platform 100.

[0037] During operation, the first driving member 310 drives the first adjusting mechanism 300 to adjust the screen printing platform 100 to move relative to the supporting assembly 200 in the first direction, and the second driving member 410 drives the second adjusting mechanism 400 to adjust the screen printing platform 100 to move relative to the supporting assembly 200 in the second direction. The first driving member 310 and the second driving member 410 are both arranged on the same side of the supporting assembly 200. When the object to be screen printed is a bag or a piece of clothing, the bag needs to be put on the screen printing platform 100 and the supporting assembly 200. The bag will block three sides of the supporting assembly 200. One side of the supporting assembly 200 where the first driving member 310 and the second driving member 410 are arranged will not be blocked, that is, the first driving member 310 and the second driving member 410 will not be blocked, and the position of the screen printing platform 100 can be adjusted normally.

[0038] In the related art, the screen printing platform cannot be taken out from the adjusting device. When screen printing a specific object, it is necessary to take the specific object off the screen printing platform and then place the specific object for the second time. After placing the specific object, screen printing is carried out again. The secondary placement of the specific object requires repeated adjustment of the position of the screen printing platform. This process is relatively cumbersome, resulting in low screen printing efficiency.

[0039] Based on this, please refer to Figure 4 and Figure 5 The screen printing machine of the present utility model further includes a magnetic member 510 and a first connecting member 520. One end of the first connecting member 520 is connected to the screen printing platform 100, and the other end is connected to the magnetic member 510. The magnetic member 510 is magnetically attracted to the supporting assembly 200. When it is necessary to separate the screen printing platform 100 from the supporting assembly 200, the screen printing platform 100 can be directly taken out by an external force. The screen printing platform 100 can be easily disassembled and assembled, and there is no need to place the object to be screen printed on the screen printing platform 100 for the second time, saving the step of adjusting the screen printing platform 100 again and improving the screen printing efficiency.

[0040] Specifically, both the magnetic member 510 and the first connecting member 520 are provided in multiple numbers. The multiple magnetic members 510 and the multiple first connecting members 520 are arranged between the screen printing platform 100 and the supporting assembly 200 so that the screen printing platform 100 is stably arranged on the supporting assembly 200. More specifically, six magnetic members 510 and first connecting members 520 are provided.

[0041] Further, the first connecting member 520 can be, but is not limited to, a wood screw. The screen printing platform 100 is made of wood material, and the magnetic member 510 can be, but is not limited to, a strong magnet. The wood screw is inserted into the screen printing platform 100 and fixedly connected to the strong magnet. The strong magnet is adsorbed on the supporting assembly 200 so that the screen printing platform 100 does not move relative to the supporting assembly 200 during normal screen printing. When the first adjusting mechanism 300 and the second adjusting mechanism 400 adjust the screen printing platform 100, that is, when an external force is applied to the screen printing platform 100, the external force is greater than the acting force of the magnetic member 510 adsorbing the supporting assembly 200, so that the screen printing platform 100 can move relative to the supporting assembly 200.

[0042] In this embodiment, please refer to Figure 5 Figure 3, the second adjusting mechanism 400 includes a third transmission shaft and a second sliding assembly 420. The second sliding assembly 420 is connected to the screen printing platform 100. One end of the third transmission shaft is connected to the second driving member 410, and the other end is connected to the second sliding assembly 420. A third sliding groove 220 is formed on the supporting assembly 200. The third sliding groove 220 is arranged along the second direction. The second sliding assembly 420 can slide in the third sliding groove 220 and drive the screen printing platform 100 to move relative to the supporting assembly 200 along the second direction. Both the second driving member 410 and the second sliding assembly 420 are arranged along the second direction. There is no need to additionally set a universal joint to achieve variable-angle power transmission, and there is no need to change the position of the transmission axis direction. The adjustment of the screen printing platform 100 in the second direction can be achieved through the transmission of the third transmission shaft.

[0043] In this embodiment, please refer to Figure 3. The screen printing machine further includes a third adjusting mechanism 600. The third adjusting mechanism 600 is arranged on the supporting assembly 200 and is connected to the screen printing platform 100. The third adjusting mechanism 600 has a third driving member 610. The third driving member 610 can drive the third adjusting mechanism 600 to adjust the screen printing platform 100 to move relative to the supporting assembly 200 along the first direction. The third adjusting mechanism 600 is arranged at an interval relative to the first adjusting mechanism 300. Specifically, the third driving member 610 can be, but is not limited to, a knob. The third adjusting mechanism 600 and the first adjusting mechanism 300 adjust the screen printing platform 100 in the same direction. The difference is that the third adjusting mechanism 600 and the second adjusting mechanism 400 are different in position in the second direction, and the structures of the third adjusting mechanism 600 and the first adjusting mechanism 300 are basically the same.

[0044] The specific structure of the first adjusting mechanism 300 is introduced below.

[0045] Specifically, please refer to Figure 3 and Figure 6, the first adjustment mechanism 300 includes a transmission assembly and a first sliding assembly 330. The first sliding assembly 330 is connected to the screen printing platform 100. One end of the transmission assembly is connected to the first driving member 310, and the other end is connected to the first sliding assembly 330. The supporting assembly 200 is provided with a first sliding groove 210. The first sliding groove 210 is arranged along the first direction. The first sliding assembly 330 can slide in the first sliding groove 210 and drive the screen printing platform 100 to move relative to the supporting assembly 200 along the first direction. Through the transmission assembly, the first driving member 310 can be set at a preset position, that is, the first driving member 310 and the second driving member 410 can be set on the same side of the supporting assembly 200. Optionally, the structure of the second sliding assembly 420 is the same as that of the first sliding assembly 330.

[0046] More specifically, the transmission assembly includes a first universal joint 321, a second universal joint 322, a first transmission shaft 323 and a second transmission shaft 324. One end of the first transmission shaft 323 is connected to the first driving member 310, and the other end is connected to one end of the first universal joint 321. The other end of the first universal joint 321 is connected to one end of the second transmission shaft 324. The other end of the second transmission shaft 324 is connected to one end of the second universal joint 322. The other end of the second universal joint 322 is connected to the first sliding assembly 330. The first transmission shaft 323 is arranged along the second direction.

[0047] Please refer to Figures 7 to 9 , the first sliding assembly 330 includes a threaded member 331 and a sliding member 332. The sliding member 332 can slide in the first sliding groove 210. A threaded hole matching the threaded member 331 is provided in the sliding member 332. One end of the threaded member 331 is connected to the second universal joint 322. Specifically, the threaded member 331 can be but is not limited to a threaded rod. More specifically, the threaded member 331 is a screw. The sliding member 332 can be but is not limited to a slider pin.

[0048] During operation, the first driving member 310 is driven to rotate about its own rotation axis, driving the first transmission shaft 323 to rotate. The first transmission shaft 323 drives the second transmission shaft 324 to rotate through the first universal joint 321, and the second transmission shaft 324 drives the threaded member 331 to rotate through the second universal joint 322, so that the threaded member 331 drives the sliding member 332 to slide in the first sliding groove 210. If the setting direction of the first driving member 310 is the same as that of the threaded member 331, the first driving member 310 must be set in the first direction. Then, the first driving member 310 and the second driving member 410 are respectively arranged on two adjacent sides of the supporting component 200. When the object to be screen-printed is a bag or a piece of clothing, one of the first driving member 310 and the second driving member 410 will be blocked, affecting the normal adjustment of the screen-printing platform 100. Through the first universal joint 321, the second universal joint 322, the first transmission shaft 323 and the second transmission shaft 324, the torque of the first driving member 310 can be transmitted to the threaded member 331, enabling the setting direction of the first driving member 310 to be perpendicular to that of the threaded member 331.

[0049] Specifically, please refer to Figure 9 , the sliding member 332 includes a protruding portion 3321 and a sliding portion 3322. The protruding portion 3321 is arranged on the sliding portion 3322. The protruding portion 3321 can slide in the first sliding groove 210, and the protruding portion 3321 can be, but is not limited to, a cylinder.

[0050] In this embodiment, the first sliding assembly 330 further includes a nut 333. The nut 333 is in threaded cooperation with the threaded member 331, and the nut 333 is arranged at one end of the sliding member 332 away from the threaded hole. With this arrangement, the threaded member 331 can drive the first driving member 310 to slide more stably.

[0051] Specifically, the nut 333 can be, but is not limited to, a square nut 333. The sliding member 332 is provided with a first side plate and a second side plate. The first side plate and the second side plate are arranged opposite to each other. The first side plate and the second side plate clamp and fix the square nut 333, restricting the rotation of the square nut 333 when the threaded member 331 rotates.

[0052] Further, please refer to Figure 7 and Figure 8 , the first sliding assembly 330 further includes an elastic member 334. One end of the elastic member 334 is connected to the nut 333, and the other end is connected to the sliding member 332 near the threaded hole. There is a gap between the threaded member 331 and the internal thread of the sliding member 332, and the gap will reduce the adjustment accuracy. By the pre-tightening effect of the elastic member 334 to compress the gap, the adjustment accuracy can be improved. Specifically, the elastic member 334 can be, but is not limited to, a spring.

[0053] Further, please refer to Figure 4 andFigure 5 The screen printing machine further includes a second connecting member 530. The second connecting member 530 is connected to the screen printing platform 100. The second connecting member 530 is provided with a second sliding groove 531. The second sliding groove 531 is arranged along the second direction. A part of the first sliding assembly 330 extends into the second sliding groove 531. When only the second adjusting mechanism 400 is turned on and the first adjusting mechanism 300 and the third adjusting mechanism 600 are turned off, the first sliding assembly 330 will not move, and the screen printing platform 100 moves relative to the supporting assembly 200 in the second direction. The provision of the second sliding groove 531 can prevent the first sliding assembly 330 from restricting the movement of the screen printing platform 100 relative to the supporting assembly 200 in the second direction. Specifically, the protruding portion 3321 extends into the second sliding groove 531.

[0054] Specifically, wood screws are provided on the side of the second connecting member 530 facing the screen printing platform 100. The screen printing platform 100 and the second connecting member 530 are fixedly connected by the wood screws. The second sliding groove 531 is a long strip-shaped sliding groove. The part of the first sliding assembly 330 extending into the second sliding groove 531 (i.e., the protruding portion 3321) is a cylinder, and the diameter of the cylinder is smaller than the width of the second sliding groove 531. With such a setting, it is possible to make the screen printing platform 100 rotate slightly relative to the supporting assembly 200, that is, when the first adjusting mechanism 300 or the second adjusting mechanism 400 is turned on, it drives a corner of the screen printing platform 100 to move and adjust, realizing the rotational adjustment of the screen printing platform 100.

[0055] Further, please refer to Figure 7 and Figure 8 The first sliding assembly 330 further includes a guiding member 335. The guiding member 335 is arranged on the supporting assembly 200. The guiding member 335 is arranged along the first direction. The sliding member 332 is slidably arranged on the guiding member 335. The guiding member 335 is used to guide the sliding member 332. Under the rotation of the threaded member 331, the sliding member 332 will also be subjected to torque. The guiding member 335 can ensure that the sliding member 332 does not rotate, but slides along the first direction. Specifically, the sliding portion 3322 slides in the guiding member 335.

[0056] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims.
