Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing equipment technology, and in particular to an integrated screen printing machine. Background Technology
[0002] Screen printing, also known as silkscreen printing, uses a squeegee to force ink through the mesh of the image area onto the substrate, creating an image identical to the original artwork. Screen printing is widely used due to its simple equipment, convenient operation, easy printing and plate making, low cost, and strong adaptability.
[0003] Most screen printing machines in related technologies adopt a circulating printing line, which is a reciprocating printing production line with a box-type drying mechanism, a box-type air-cooling mechanism, and a printing mechanism. For example, the circulating screen printing machine of Chinese Patent (Publication No.: CN221315457U, by the same creator as this application) uses a stacking mechanism to stack carrier plates into an empty material frame and to transfer the frame of a preset number of stacked carrier plates to the drying oven mechanism. The drying oven mechanism dries the target printed products of the same batch simultaneously. Then, the products are transferred and air-cooled by a cooling conveyor mechanism, and the cooled target printed products are divided by a material distribution mechanism. Although this solves the problem of ink overflow in screen printing machines in related technologies, which affects the quality of printed products, it has the problems of large space occupation, many equipment components required, limited adaptability to various scenarios, and high equipment cost.
[0004] Currently, no effective solution has been proposed to address the issues of large footprint and high equipment cost associated with screen printing machines in related technologies. Utility Model Content

The synchronous drive unit is used to drive the rotating shafts through the drive shafts to move the two vertical chain conveyor belts synchronously vertically. The synchronous vertical movement of the two vertical chain conveyor belts drives the two pallets located at the same position to support the corresponding carrier plates and move them vertically.
[0014] In some embodiments, both the first and second pusher assemblies include a slide and a pusher rod. The slide is kinetically connected to the pusher rod and is used to drive the pusher rod to move from the first stacking transfer assembly toward the second stacking transfer assembly or from the fourth stacking transfer assembly toward the third stacking transfer assembly, so that the pusher rod pushes the corresponding carrier plate into place.
[0015] In some embodiments, the oven mechanism includes a blower dryer that connects the inner chambers of the first transfer unit and the second transfer unit. The blower dryer, located on the first transfer unit, is used to bake a carrier plate carrying a first printed product and being vertically transferred between the first and second stacking transfer components to dry the first printed product into a second printed product.

[0016] Compared with the prior art, the integrated screen printing machine provided in this application embodiment adopts a first conveying unit and a second conveying unit respectively arranged on the horizontal sides of the printing mechanism. The first conveying unit conveys the corresponding carrier plate to the first transfer unit, which adopts a stacking-type up-and-down conveying transfer method. The corresponding printed product completes one drying process in the first transfer unit during the process of moving up and down. A third conveying unit connects the first transfer unit with the second transfer unit, which also adopts a stacking-type up-and-down conveying transfer method. The printed product that has been dried in the first transfer unit is then conveyed to the second transfer unit for drying again. The printing press moves upwards and then downwards, completing a second drying process during this movement. The printed material, after the second drying, is then conveyed by the second conveyor unit to the unloading station for unloading or to the printing mechanism for the next printing cycle. Through the conveying methods within the first and second transfer units, the drying process and time are extended within a limited space, improving baking efficiency and thus enhancing printing quality. Simultaneously, the printing mechanism and the stacking and unloading mechanism are cyclically connected through the first, second, and third conveyor units to form a cyclical screen printing system, reducing equipment components and lowering equipment costs within a limited space.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0036] Please see Figures 1 to 6 The integrated screen printing machine of this application embodiment includes a printing mechanism 200 for screen printing printed materials and mounted on a frame 100. A first conveying unit 300 and a second conveying unit 400 are respectively provided on both lateral sides of the printing mechanism 200. The first conveying unit 300 and the second conveying unit 400, on their opposite sides from the printing mechanism 200, are respectively connected to a first transfer unit 51 and a second transfer unit 52 of a stacking and unloading mechanism 500. Both the first transfer unit 51 and the second transfer unit 52 are equipped with an oven mechanism 600 for baking the printed materials, and are connected via a third conveying unit 700.
[0037] The first conveying unit 300 is used to convey the carrier plate 800 carrying the first printed product from the loading station 001 to the first transfer unit 51 one by one. The first printed product includes one of the following: the product to be printed after loading, or the product that has been screen printed and conveyed by the printing mechanism 200.
[0038] In this embodiment, the loading station 001 is located on the right side of the printing mechanism 200. That is, for unprinted products to be printed, they need to be placed on the corresponding carrier plate 800 and conveyed sequentially through the first transfer unit 51 and the second transfer unit 52 along with the carrier plate 800. After drying once, the products to be printed are conveyed to the printing mechanism 200 for the first printing. For the first printed products output from the printing mechanism 200, after being conveyed through the loading station, they are also conveyed sequentially through the first transfer unit 51 and the second transfer unit 52 along with the corresponding carrier plate 800. In order to dry and cure the ink that has been printed once in the first transfer unit 51 and the second transfer unit 52, ink overflow will be avoided during the next printing.
[0039] In this embodiment, the first transfer unit 51 extends its travel distance in vertical space through an internal stacking and transfer method (e.g., by first rising and then falling, extending the distance the carrier plate 800 is transported). Under the condition of cyclic transport, it extends the baking time to ensure that the printed product or the ink is sufficiently dry, ensuring the quality of the next printing (one of the multiple printings). In this embodiment, the corresponding drying oven mechanism 600 generates hot air and transfers the generated hot air to the inner chamber of the first transfer unit 51 to dry the corresponding printed product a corresponding number of times.
[0040] The third conveying unit 700 is used to convey the carrier plate 800 carrying the second printed product to the second transfer unit 52 one by one. The second printed product is the first printed product that has been stacked and transferred in the first transfer unit 51 and has been baked.
[0041] In this embodiment, the third conveying unit 700 serves as a bridge between the first transfer unit 51 and the second transfer unit 52. Through the third conveying unit 700, the printed material or the material to be printed that has been dried in the first transfer unit 51 is conveyed to the second transfer unit 52 for secondary drying. At the same time, the inner chamber of the third conveying unit 700 is connected to the inner chambers of the first transfer unit 51 and the second transfer unit 52 respectively. When the carrier plate 800 carrying the printed material is conveyed along the third conveying unit 700, a constant dimension is maintained to ensure the drying effect in the first transfer unit 51.
[0042] In this embodiment, the second transfer unit 52 extends its travel distance in vertical space through an internal stacking and transfer method (e.g., by first rising and then falling, extending the distance the carrier plate 800 is conveyed). Under the condition of cyclic conveying, it extends the baking time to ensure that the printed product or the ink is sufficiently dry, ensuring the quality of the next printing (one of the multiple printings). In this embodiment, the corresponding oven mechanism 600 generates hot air and transfers the generated hot air to the inner chamber of the second transfer unit 52 to dry the corresponding printed product a corresponding number of times.
[0043] It should be understood that the first transfer unit 51 and the second transfer unit 52 are symmetrical structures set with the printing mechanism 200 as the center of symmetry. The distance that the carrier plate 800 carries the corresponding printed material to rise in the first transfer unit 51 is less than the distance in the second transfer unit 52, while the distance that the carrier plate 800 carries the corresponding printed material to fall in the first transfer unit 51 is greater than the distance in the second transfer unit.
[0044] In this embodiment, the corresponding drying oven mechanism 600 generates hot air and transfers the generated hot air to the inner chamber of the first transfer unit 51 to dry the corresponding printed matter a corresponding number of times.
[0045] The second conveying unit 400 is used to convey the carrier plate 800 carrying the third printed product to the unloading station 002 and / or the printing mechanism 200 one by one. The third printed product is the second printed product that has been stacked and transferred and baked in the second transfer unit 52.
[0046] In this embodiment, after the corresponding printed product is conveyed out of the second transfer unit 52, if the number of printing times of the corresponding printed product reaches the set number (e.g., 3 times), the carrier plate 800 carrying the corresponding printed product will be unloaded after the corresponding printed product arrives at the unloading station 002; while for printed products that have not completed the set number of printing times (e.g., products to be printed that have not been printed), the carrier plate 800 carrying the corresponding printed product will carry the corresponding printed product through the unloading station 002 and be conveyed to the printing mechanism 200 for printing.
[0047] In this embodiment, the printing mechanism 200 is used to print the third printed product that flows through the unloading station 002 and is carried on the corresponding carrier plate 800. That is, when the carrier plate 800 carrying the third printed product is conveyed to the printing mechanism 200, the printing mechanism 200 starts the screen printing operation and prints the preset target pattern on the corresponding third printed product. It should be noted that, whether it is the first printing or the repeated printing, when the corresponding printed product flows through the unloading station 002 and arrives at the printing station where the printing mechanism is located, the printed product to be printed has already completed the corresponding drying and air cooling operations (during the conveying process of the third conveying unit 700), and can start printing when it arrives at the printing mechanism 200.
[0048] In the aforementioned integrated screen printing machine, a first conveying unit 300 and a second conveying unit 400 are respectively arranged on both sides of the printing mechanism 200. The first conveying unit 300 conveys the corresponding carrier plate 800 to the first transfer unit 51, which adopts a stacking-type up-and-down conveying transfer method. The corresponding printed product completes one drying process in the first transfer unit 51 during the process of first rising and then falling. A third conveying unit 700 connects the first transfer unit 51 to the second transfer unit 52, which also adopts a stacking-type up-and-down conveying transfer method. The printed product that has been dried in the first transfer unit 51 is then conveyed to the second transfer unit 52 for another process of first rising and then falling. The printing material then descends and moves, completing a second drying process during this movement. The printed material after the second drying is then conveyed by the second conveyor unit 400 to the unloading station 002 for unloading or to the printing mechanism 200 for the next cycle of printing. Through the conveying method inside the first transfer unit 51 and the second transfer unit 52, the drying stroke and time are extended within a limited space, improving baking efficiency and thus enhancing printing quality. At the same time, the printing mechanism 200 and the stacking and unloading mechanism 500 are cyclically connected through the first conveyor unit 300, the second conveyor unit 400, and the third conveyor unit 700 to form a cyclic screen printing system, reducing equipment components and lowering equipment costs within a limited space.
[0049] In order to receive and print printed materials, refer to Figures 1 to 4 In some embodiments, the printing mechanism 200 includes a base plate 21 mounted on a frame 100. A vacuum adsorption stage 22 is mounted on the base plate 21, and alignment devices 23 are provided around the vacuum adsorption stage 22. The base plate 21 also includes a first conveyor 25 connected to a top support drive unit 24. The base plate 21 further includes a support frame 26, on which a lifting plate 28, driven by a first lifting drive unit 27, is mounted. A screen printing head 29, capable of sliding laterally along the lifting plate 28, is mounted on the lifting plate 28. The lifting plate 28 is also connected to a screen support frame 210 located above the vacuum adsorption stage 22.
[0050] In this embodiment, the screen support frame 210 is connected to two horizontal arms (not labeled) of the vertical lifting plate 28 via a pull rod (not labeled in the figure). This allows the screen support frame 210 to be located on the longitudinal front side of the lifting plate 28 and above the vacuum adsorption stage 22. When the lifting plate 28 moves vertically downward, the screen supported on the screen support frame 210 can be placed on the carrier plate 800 located on the vacuum adsorption stage 22, so that the pattern on the screen can be screen-printed onto the printed product by the printing head 29.
[0051] The top support drive unit 24 is used to drive the first conveyor 25 to be raised to dock with the second conveying unit 400 so that the first conveyor 25 can receive the carrier plate 800 carrying the third printed product, and after the first conveyor 25 conveys the corresponding carrier plate 800 to the vacuum adsorption stage 22, it drives the first conveyor 25 to be lowered to place the corresponding carrier plate 800 on the vacuum adsorption stage 22.
[0052] In this embodiment, the top support drive unit 24 is used to provide power to drive the first conveyor 25 to move vertically, and to move the first conveyor 25 between a position where the carrier plate 800 can be placed on the vacuum adsorption table 22 and a position flush with the first conveying unit 300 and the second conveying unit 400. The position flush with the first conveying unit 300 and the second conveying unit 400 is used to enable the first conveyor 25 to receive the corresponding carrier plate 800 or to transport the carrier plate 800 carrying the printed product that has been printed once to the first conveying unit 300.
[0053] In this embodiment, the top support drive unit 24 includes, but is not limited to, a motor and a cylinder.
[0054] The alignment device 23 is used to calibrate the carrier plate 800 placed on the vacuum adsorption stage 22 so that the corresponding third print is located in the preset printing position.
[0055] In this embodiment, during the initial loading of the carrier plate 800, due to the relatively arbitrary placement, a deviation may occur between the area to be printed on the printed product and the area on the screen printing plate after loading. Therefore, the carrier plate 800 needs to be positionally corrected to ensure that the pattern on the screen printing plate is correctly printed onto the corresponding area of the product. Simultaneously, after the carrier plate 800 prints once and then returns to the printing mechanism 200 via a cyclic conveyor, the carrier plate 800 will experience some movement, at least in the lateral direction. For example, between the two carrier plate conveyors 31... When the material is being transported, if a single material deviates from its position, the positioning sensor on the carrier conveyor 31 will detect the positional shift and perform some correction. However, there will still be some deviation. The deviations generated by the transport of multiple carrier conveyors 31 and the material transfer process of the first transfer unit 51 and the second transfer unit 52 will accumulate to produce a large deviation. At this time, alignment is also required. In this embodiment, the method of limiting and adjusting the position in the horizontal and vertical directions is adopted to align the corresponding carrier 800 to the target area, so that the corresponding pattern can be screen-printed on the corresponding product to be printed.
[0056] The first lifting drive unit 27 is used to drive the lifting plate 28 to raise the screen support frame 210 and the screen printing head 29 to a preset position directly above the vacuum adsorption table 22 before the first conveyor 25 receives and conveys the corresponding carrier plate 800 to the vacuum adsorption table 22, and to drive the lifting plate 28 to drive the screen support frame 210 to place the screen on the third printed product after the corresponding third printed product is in the preset printing position.
[0057] In this embodiment, the first lifting drive unit 27 provides power to drive the lifting plate 28 to slide vertically along the support frame 26, thereby driving the screen holder 210 and the screen printing head 29 to rise and fall vertically. In this embodiment, in order to ensure that the carrier plate 800 can be loaded smoothly, before the first conveyor 25 receives and transports the carrier plate 800 to the vacuum adsorption table 22, the lifting plate 28 is driven to move the screen holder 210 and the screen printing head 29 vertically upward to leave enough space and avoid interfering with the loading of the first conveyor 25. In this embodiment, after the first conveyor 25 completes the corresponding loading, screen printing is performed. At this time, the screen holder 210 needs to move the screen to the carrier plate 800, and the screen needs to contact the product to be printed on the carrier plate 800. At the same time, the screen printing head 29 also needs to move to the screen and print the pattern on the screen onto the corresponding product.
[0058] It should be noted that the first lifting drive unit 27 includes, but is not limited to, an electric cylinder, a servo motor, and a pneumatic cylinder; in this embodiment, an electric cylinder is preferred; it should also be noted that any of the above first lifting drive units 27 are suitable for the first lifting drive unit 27 of this application embodiment. It is understood that how the corresponding lifting drive unit 27 is driven is clear to those skilled in the art and is not a limitation imposed on those who are not clear about it.
[0059] After the screen is placed on the third print, the screen printing head 29 is driven to slide laterally to screen print the third print.
[0060] Understandably, with this setup, the first lifting drive unit 27 drives the lifting plate 28, the screen printing head 29, and the screen support frame 210 to move as needed, satisfying the preset printing requirements while ensuring smooth loading and unloading.
[0061] For printing purposes, refer to Figures 2 to 4In some embodiments, the screen printing head 29 includes a slide 291, a squeegee bracket 292, a second lifting drive unit 293, a squeegee adjustment drive unit 294, a printing squeegee 295, and a back-inking blade 296. The slide 291 is movably connected to a first slide rail 211 mounted on a lifting plate 28 and extending laterally, and is drivenly connected to a horizontal drive unit 212 mounted on the lifting plate 28.
