Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, and in particular to a safety protection mechanism and a semi-automatic screen printing machine. Background Technology

[0002] Colored crystal glass is an ideal new type of decorative material. It involves printing a colored coating or a transparent colored coating with ink onto the surface of ordinary flat glass or tempered glass, which requires the use of a screen printing machine.

[0003] A search revealed that patent CN221584781U discloses an automatic screen printing machine. This technical solution has the following problems:

[0004] The existing method of placing the glass to be screen-printed directly into the placement slot can easily cause workers' hands to be pinched, resulting in injury and making it difficult to protect workers, which greatly reduces safety.

[0005] To address the aforementioned issues, this utility model document proposes a safety protection mechanism and a semi-automatic wire mesh machine. Utility Model Content

[0006] This utility model provides a safety protection mechanism and a semi-automatic screen printing machine, which solves the problem in the prior art where the glass to be screen printed is placed directly into the placement slot, which can easily cause the worker's hand to be pinched, resulting in injury and making it difficult to protect the worker, thus greatly reducing safety.

[0007] This utility model provides the following technical solution:

[0008] A semi-automatic wire mesh machine, comprising:

[0009] A frame, with a support block welded to its top side, and a screen printing structure provided on one side of the support block for screen printing operations on glass;

[0010] A drive groove is provided on one side of the support block, and a motor is fixedly installed on the top of the support block. The output end of the motor passes through the top side of the support block and extends into the interior of the drive groove.

[0011] In one possible design, the output end of the motor is fixedly equipped with a lead screw via a coupling. The bottom end of the lead screw is rotatably connected to the bottom side of the inner wall of the drive groove. A threaded block is threadedly connected to the outer wall of the lead screw. The threaded block is slidably connected to the inside of the drive groove. The threaded block is fixedly installed on one side of the screen printing structure.

[0012] In one possible design, a limiting block is fixedly installed on one side of the screen-printed structure, and a limiting groove is provided on one side of the support block for the limiting block to slide. A limiting rod is welded between the top side and the bottom side of the inner wall of the limiting groove, and a limiting hole is provided inside the limiting block for sliding connection to the outer wall of the limiting rod.

[0013] A semi-automatic screen printing machine includes a storage cavity located at the top of the machine frame for placing and processing glass to be screen printed.

[0014] The transfer mechanism, mounted on the frame, is used to transfer the glass to be screen-printed to the appropriate screen-printing position.

[0015] In one possible design, the transfer mechanism includes a chute, a tray, an anti-slip pad, a drive plate, and an electric telescopic rod. The chute is located inside the frame and communicates with the storage cavity. The tray is slidably connected inside the chute and is used to support, lift, and move the glass. The electric telescopic rod is fixedly installed on the bottom side of the inner wall of the frame. The drive plate is fixedly mounted on the output end of the electric telescopic rod, and one side of the drive plate is welded and fixed to one side of the tray.

[0016] In one possible design, the top side of the tray has four storage slots, and each storage slot is equipped with a suction cup for adsorbing and fixing the glass. The bottom of the suction cup is rotatably connected to a screw via a rotating shaft. The screw is threaded into the bottom side of the tray, and a knob is welded to the bottom end of the screw.

[0017] In one possible design, the top side of the tray is provided with an anti-slip pad that fits against the glass.

[0018] In this application, firstly, the frame serves as an overall support structure, with its top support block welded and fixed for mounting the screen printing structure and drive components. Then, an electric telescopic rod pushes the drive plate, causing the tray to move horizontally along the slide, smoothly transporting the tray from the storage cavity to the outside of the frame. This facilitates the placement of glass onto the tray by the staff, and the absence of obstructions on the tray helps prevent the staff from pinching their hands when placing the glass, enhancing operational convenience and avoiding injury to the staff, thus greatly improving safety. When the glass is placed on the tray, it comes into contact with the anti-slip pad, which further increases friction and prevents the glass from sliding during transportation. Simultaneously, rotating the knob drives the screw to rotate, and the screw is connected to the threaded connection inside the bottom of the frame, which can drive the suction cup rotating at the top to rise. When the suction cup contacts the glass, it creates a negative pressure adsorption, which helps to adsorb and fix the glass, achieving a stable positioning effect and preventing the glass from shifting. When releasing the glass later, simply move the suction cup down into the storage slot by the screw, and the suction cup will detach from the glass, achieving the effect of releasing the fixation.

[0019] Once the glass is in place and fixed, the electric telescopic rod moves the tray and glass to a new position, allowing the glass to be transported to the storage cavity corresponding to the screen-printed structure. At this point, the motor is activated, driving the lead screw to rotate and causing the threaded block to slide up and down along the drive groove. This adjusts the height of the screen-printed structure to accommodate glass of varying thicknesses. Simultaneously, the screen-printed structure utilizes a limiting block and limiting groove to ensure stable vertical movement. A limiting rod passes through the limiting hole in the limiting block to prevent the screen-printed structure from shifting or shaking during movement, ensuring screen-printing accuracy. During operation, the squeegee in the screen printing structure is used to scrape ink through the screen and transfer it to the glass surface. After printing, the ink return blade in the screen printing structure scrapes the ink back to the starting position to ensure uniform ink distribution. The screen frame is stretched with fine screen mesh, which has hollowed-out areas (through holes) and closed areas (ink-blocking parts) according to the pattern. The squeegee moves laterally on the screen surface, squeezing the ink through the through holes of the pattern part of the screen and depositing it on the glass surface to form the desired pattern. The ink return blade then scrapes the excess ink back to the starting end to ensure the uniformity of ink for the next printing.

[0020] In this utility model, the safety protection mechanism and semi-automatic screen printing machine can smoothly move the pallet from the storage cavity to the outside of the machine frame through the transfer mechanism, which makes it convenient for workers to place the glass on the pallet. Moreover, there are no obstructions on the pallet, which helps to prevent workers from pinching their hands when placing the glass.

[0021] In this utility model, the safety protection mechanism and semi-automatic screen making machine, through the setting of the storage groove, suction cup, screw and knob structure, can drive the suction cup rotating at the top to rise, and at the same time form a negative pressure adsorption, which is conducive to adsorbing and fixing the glass, achieving a stable positioning effect and preventing the glass from shifting.

[0022] In this invention, the pallet can be smoothly moved from the storage chamber to the outside of the frame, making it convenient for workers to place the glass on the pallet. Since there are no obstructions on the pallet, it helps to prevent workers from getting their hands pinched when placing the glass, enhancing the convenience of operation and avoiding injury to workers, thus protecting them and greatly improving safety.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0030] The existing screen printing machine industry has a problem that when the glass to be screen printed is placed directly into the placement tank, the placement tank can easily cause the operator's hand to be pinched, resulting in injury and making it difficult to protect the operator, which greatly reduces safety. To address this problem, this solution is designed as a screen printing machine.

[0031] Please refer to Figures 1-4 A screen printing machine, comprising:

[0032] The frame 1 has a support block 2 welded to its top side, and a screen printing structure 3 is provided on one side of the support block 2 for screen printing operations on glass.

[0033] A drive groove 14 is provided on one side of the support block 2. A motor 15 is fixedly installed on the top of the support block 2. The output end of the motor 15 passes through the top side of the support block 2 and extends into the interior of the drive groove 14. A lead screw 16 is fixedly installed on the output end of the motor 15 via a coupling. The bottom end of the lead screw 16 is rotatably connected to the bottom side of the inner wall of the drive groove 14. A threaded block 17 is threadedly connected to the outer wall of the lead screw 16. The threaded block 17 is slidably connected to the interior of the drive groove 14 and is fixedly installed on one side of the screen printing structure 3. When the motor 15 is turned on, the motor 15 drives the lead screw to rotate, causing the threaded block 17 to slide up and down along the drive groove 14, thereby adjusting the height of the screen printing structure 3 to meet the processing needs of glass of different thicknesses.

[0034] A limiting block 19 is fixedly installed on one side of the screen printing structure 3. A limiting groove 18 is provided on one side of the support block 2 for the limiting block 19 to slide. A limiting rod 20 is welded between the top and bottom sides of the inner wall of the limiting groove 18. A limiting hole is provided inside the limiting block 19 and slidably connected to the outer wall of the limiting rod 20. The screen printing structure 3 cooperates with the limiting block 19 and the limiting groove 18 to ensure the stability of vertical movement. The limiting rod 20 passes through the limiting hole of the limiting block 19 to prevent the screen printing structure 3 from shifting or shaking during movement and to ensure screen printing accuracy.

[0035] A safety protection mechanism for installation on a semi-automatic screen printing machine includes a storage cavity 4, which is located on the top of the frame 1 for placing and processing glass to be screen printed.

[0036] The transfer mechanism, mounted on the frame 1, is used to transfer the glass to be screen-printed to a suitable screen-printing position. The transfer mechanism includes a slide 5, a tray 6, an anti-slip pad 7, a drive plate 8, and an electric telescopic rod 9. The slide 5 is located inside the frame 1 and communicates with the storage cavity 4. The tray 6 is slidably connected inside the slide 5 to support, lift, and move the glass. The electric telescopic rod 9 is fixedly installed on the bottom inner wall of the frame 1. The drive plate 8 is fixedly mounted on the output end of the electric telescopic rod 9. One side of the drive plate 8 is welded to one side of the tray 6. The electric telescopic rod 9 pushes the drive plate 8, causing the tray 6 to move horizontally along the slide 5, smoothly transferring the tray 6 from the storage cavity 4 to the outside of the frame 1. This facilitates the placement of glass onto the tray 6 by the operator, and the absence of obstructions on the tray 6 helps prevent the operator's hand from being pinched when placing the glass, enhancing operational convenience and preventing injury to the operator, thus greatly improving safety.

[0037] The top side of the tray 6 has four storage slots 10, and each storage slot 10 is equipped with a suction cup 11 for adsorbing and fixing the glass. The bottom of the suction cup 11 is rotatably connected to a screw 12 via a rotating shaft. The screw 12 is threaded into the bottom side of the tray 6. A knob 13 is welded to the bottom end of the screw 12. Rotating the knob 13 drives the screw 12 to rotate. By using the threaded connection between the screw 12 and the bottom side of the frame 1, the suction cup 11 rotating at the top can be driven to rise. When the suction cup 11 contacts the glass, it will form a negative pressure adsorption, which is conducive to adsorbing and fixing the glass, achieving a stable positioning effect and preventing the glass from shifting.

[0038] The top side of the tray 6 is provided with an anti-slip pad 7 that fits against the glass. When the glass is placed on the tray 6, it will come into contact with the anti-slip pad 7. The anti-slip pad 7 further increases the friction and prevents the glass from sliding during transportation.

[0039] This application can be used in the field of screen printing machines, or in other fields applicable to this application.

[0040] The screen printing structure 3 is the same as the screen printing structure 2 mentioned in Chinese Patent Authorization Announcement No. CN221584781U, and its structure and mechanism will not be described in detail here.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the silkscreen structure 3, the electric telescopic rod 9, and the motor 15 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
