[0002] Screen printing machine, as one of the common types of printing machines, is often used for printing on clothing or fabrics.
[0003] When the existing screen printing machine is in use, the printing plate and the mounting frame are usually mounted on each other, and then the fixing frame and the fixing frame are mounted on each other, and then the substrate is placed on the printing platform and the position of the substrate is adjusted. After the position of the substrate is adjusted, the mounting frame is driven downward by the machine body, and at the same time, the mounting frame is driven downward and the printing plate and the substrate surface are driven to contact each other, and then the ink is poured onto the printing plate and the ink is evenly spread on the printing plate. At this time, the ink will print the substrate according to the pattern on the printing plate.
[0004] When substrates need to be printed in batches, in order to prevent the printing positions of each substrate from shifting, the staff usually uses tape or other methods to ensure the uniformity of the placement boundaries of the substrates. However, when replacing the substrates on the printing platform, the staff needs to rely on their own experience to observe the position of the replaced substrates. After working for a long time, the staff will suffer from visual fatigue, which can easily cause the position of the substrates to deviate, affecting the printing effect. Utility Model Content

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an environmentally friendly and efficient screen printing machine, including a body, a mounting bracket, a mounting frame, and a printing platform that are connected to each other, an L-shaped plate is fixedly connected to one side of the printing platform, and a rotating frame is rotatably connected to the side wall of the L-shaped plate, the rotating frame and the bottom of the L-shaped plate are fitted with each other, and the rotating frame and the L-shaped plate are clamped to each other through a clamping assembly, a positioning block is fixedly connected to the rotating frame, a positioning groove for inserting the positioning block is provided at the bottom of the mounting frame, an adjusting assembly for adjusting the position of the mounting frame is provided on the mounting bracket, and a positioning assembly for positioning the position of the substrate is provided on the printing platform.
[0007] By adopting the above technical scheme, when using a screen printing machine to print a substrate, the printing plate and the mounting frame are mounted to each other, and then the mounting frame and the mounting rack are mounted to each other, and then the substrate is placed on the printing platform, and at the same time, the restriction between the rotating frame and the L-shaped plate is removed by the clamping component, and the rotating frame is driven to rotate upward, and then the substrate is placed on the L-shaped plate, and then the rotating frame is driven to rotate downward, and the L-shaped plate and the rotating frame are clamped to each other by the clamping component. At this time, the substrate is affected by the L-shaped plate and the rotating frame, so that the substrate is clamped and fixed by the L-shaped plate and the rotating frame, and then the size of the substrate is positioned by the positioning component, and then the mounting rack is driven by the machine body to drive the mounting frame to move downward, and continuously apply pressure, and then the position of the mounting frame is adjusted by the adjusting component so that the positioning groove at the bottom of the mounting frame is The positioning block is inserted into the positioning groove and the printing plate and the substrate are driven to contact each other. Then, ink is poured onto the printing plate and the ink is spread with a scraper. At this time, the ink will print the pattern onto the substrate through the printing plate, thereby completing the printing of the substrate. When the substrates need to be printed in batches, the mounting frame is lifted upward through the machine body, and then the L-shaped plate and the rotating frame are driven to cancel the clamping, and then the substrate is taken out and replaced. When replacing, the substrate and the positioning assembly are brought into contact with each other, and then the L-shaped plate and the rotating frame are used to clamp the substrate. At this time, the replaced substrate is in the same position as before the replacement, and then the above operation is repeated to print the substrate, thereby avoiding the problem of deviation in the position of the substrate and improving the printing effect during batch printing.
[0008] The utility model is further configured as follows: the clamping assembly includes a clamping block fixedly connected to the side wall of the rotating frame, the side wall of the L-shaped plate is provided with a clamping groove for the clamping block to clamp, the rotating frame and the L-shaped plate are rotatably connected via a rotating rod, the rotating rod and the rotating frame are connected via a torsion spring, and when the clamping block and the clamping groove are clamped with each other, the rotating frame and the bottom of the L-shaped plate fit each other and the torsion spring is in a deformed state.
[0009] By adopting the above-mentioned clamping assembly, when it is necessary to drive the L-shaped plate and the rotating frame to clamp each other, the rotating frame is driven to rotate downward, and at the same time, the rotating frame and the bottom of the L-shaped plate are driven to fit each other, and the clamping block is driven to enter the clamping slot and clamp with the clamping slot. At this time, the rotating frame is affected by the clamping block and the clamping slot and cannot rotate, thereby achieving the effect of clamping the L-shaped plate and the rotating frame to clamp each other. When it is necessary to drive the L-shaped plate and the rotating frame to separate from each other, a pulling force is applied to the rotating frame to drive the clamping block and the clamping slot to cancel the clamping and separate from each other. At the same time, the torsion spring loses its restriction and begins to deform and recover, and drives the rotating frame to rotate upward, thereby achieving the effect of driving the L-shaped plate and the rotating frame to separate from each other.

[0011] By adopting the above-mentioned adjustment component, when the installation frame and the installation rack need to be installed to each other, the installation frame is inserted into the installation rack, and the installation rack and the installation frame are fixed to each other by the fixing parts. When the position of the installation frame needs to be adjusted, the screw rod is driven to rotate, and the screw rod drives the movable plate to move along the slide groove.

[0013] By adopting the above-mentioned fixing parts, when the mounting frame and the mounting bracket need to be mounted to each other, the mounting frame is inserted into the mounting bracket, and the mounting frame and the side walls of the abutment plate are driven to contact each other, and then pressure is applied to the mounting frame. At this time, the abutment plate is affected by the inclined surfaces on both sides and begins to move toward the moving plate, while driving the spring to deform and compress. The elastic potential energy released by the spring can drive the abutment plate and the side walls of the mounting frame to abut each other. At this time, the mounting frame is affected by the abutment plate and cannot be separated from the mounting bracket, thereby achieving the effect of fixing the mounting bracket and the mounting frame to each other.

When the substrate on the printing platform needs to be replaced, the restriction on the substrate is cancelled by the rotating frame and the L-shaped plate, and it is taken out, and then the replaced substrate and the side wall of the limiting plate are brought into contact with each other, and then the substrate is clamped again by the rotating frame and the L-shaped plate. At this time, the replaced substrate is affected by the limiting plate, so that the position of the replaced substrate can be kept consistent with that of the substrate before replacement, thereby achieving the effect of positioning the substrate.
[0016] The utility model is further configured as follows: the limiting member includes a through slot opened on one of the side walls of the fixed plate, the side wall of the through slot is rotatably connected to a rotating plate, the side wall of the rotating plate is fixedly connected to an anti-skid layer, and when the anti-skid layer and the side wall of the printing platform abut against each other, the rotating plate and the through slot are clamped with each other.

At this time, the limiting plate loses the restriction and can move on the printing platform. When it is necessary to fix the limiting plate, the rotating plate is driven to rotate and lock with the through slot. At this time, the anti-skid layer and the printing platform are in contact with each other. At this time, the limiting plate is affected by the friction between the anti-skid layer and the printing platform, so that the limiting plate cannot move on the printing platform, thereby achieving the effect of limiting the limiting plate.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0033] An environmentally friendly and efficient screen printing machine, such as Figure 1-Figure 8 As shown, it includes a body 1, a mounting frame 2, a mounting frame 3, and a printing platform 4 that are interconnected. An L-shaped plate 5 is fixedly connected to one side of the printing platform 4. A rotating frame 6 is rotatably connected to the side wall of the L-shaped plate 5. The rotating frame 6 and the bottom of the L-shaped plate 5 fit each other. The rotating frame 6 and the L-shaped plate 5 are clamped to each other through a clamping assembly. A positioning block 7 is fixedly connected to the rotating frame 6. A positioning groove 8 for inserting the positioning block 7 is provided at the bottom of the mounting frame 3. An adjusting assembly for adjusting the position of the mounting frame 3 is provided on the mounting frame 2. A positioning assembly for positioning the position of the substrate is provided on the printing platform 4.
[0034] When the screen printing machine is used to print the substrate, the printing plate and the mounting frame 3 are mounted on each other, and then the mounting frame 3 and the mounting frame 2 are mounted on each other, and then the substrate is placed on the printing platform 4, and at the same time, the restriction between the rotating frame 6 and the L-shaped plate 5 is removed by the clamping assembly, and the rotating frame 6 is driven to rotate upward, and then the substrate is placed on the L-shaped plate 5, and then the rotating frame 6 is driven to rotate downward, and the L-shaped plate 5 and the rotating frame 6 are clamped with each other by the clamping assembly. At this time, the substrate is affected by the L-shaped plate 5 and the rotating frame 6, so that the substrate is clamped and fixed by the L-shaped plate 5 and the rotating frame 6. Subsequently, the size of the substrate is positioned by the positioning component, and then the mounting frame 2 is driven by the machine body 1 to move the mounting frame 3 downward and continuously apply pressure, and then the position of the mounting frame 3 is adjusted by the adjusting component to move the position of the positioning groove 8 at the bottom of the mounting frame 3. When the positioning groove 8 moves to align with the position of the positioning block 7, the positioning block 7 is inserted into the positioning groove 8, and the printing plate and the substrate are driven to contact each other, and then the ink is poured onto the printing plate, and the ink is spread with a scraper. At this time, the ink will print the pattern onto the substrate through the printing plate, thereby completing the printing of the substrate.
[0035] When it is necessary to print the substrates in batches, the mounting frame 2 is lifted upwards through the machine body 1, and then the L-shaped plate 5 and the rotating frame 6 are driven to cancel the clamping, and then the substrate is taken out and replaced. When replacing, the substrate and the positioning component are brought into contact with each other, and then the substrate is clamped by the L-shaped plate 5 and the rotating frame 6. At this time, the position of the replaced substrate is consistent with that before replacement, and then the above operation is repeated to print the substrate, so as to avoid the problem of deviation in the position of the substrate and improve the printing effect during batch printing.
[0036] like Figure 1 , Figure 2 , Figure 6 As shown, the clamping assembly includes a clamping block fixedly connected to the side wall of the rotating frame 6, and a clamping groove for clamping the clamping block is opened on the side wall of the L-shaped plate 5. The rotating frame 6 and the L-shaped plate 5 are rotatably connected through a rotating rod 11, and the rotating rod 11 and the rotating frame 6 are connected through a torsion spring 12. When the clamping block and the clamping groove are mutually clamped, the bottom of the rotating frame 6 and the L-shaped plate 5 fit each other and the torsion spring 12 is in a deformed state. When it is necessary to drive the L-shaped plate 5 and the rotating frame 6 to clamp each other, the rotating frame 6 is driven to rotate downward, and at the same time, the rotating frame 6 and the bottom of the L-shaped plate 5 are driven to rotate. The locking block 12 and the locking slot 14 are in close contact with each other, and the locking block is driven into the locking slot and is locked with the locking slot. At this time, the rotating frame 6 is affected by the locking block and the locking slot and cannot rotate, thereby achieving the effect of making the L-shaped plate 5 and the rotating frame 6 lock each other. When it is necessary to drive the L-shaped plate 5 and the rotating frame 6 to separate from each other, a pulling force is applied to the rotating frame 6 to drive the locking block and the locking slot to cancel the locking and separate from each other. At the same time, the torsion spring 12 loses its restriction and begins to deform and recover, and drives the rotating frame 6 to rotate upward, thereby achieving the effect of driving the L-shaped plate 5 and the rotating frame 6 to separate from each other.
[0037] like Figure 1-Figure 5As shown, the adjustment component includes two movable plates 13 slidably connected to the side of the mounting frame 2 away from the mounting frame 3, and a sliding groove 14 for the two movable plates 13 to slide is provided on the side of the mounting frame 2 away from each other, and fixed frames 15 are fixedly connected to both sides of the mounting frame 2. The bottoms of the movable plates 13 and the fixed frames 15 are in contact with each other, and a screw 16 is rotatably connected in the fixed frame 15. The screw 16 penetrates the movable plate 13 to the outside and is threadedly connected to the movable plate 13. The movable plate 13 and the mounting frame 3 are mounted to each other through a fixing member, and the fixing member includes an abutment plate 17 arranged obliquely on both sides, and a connecting rod 18 is fixedly connected to the side wall of the abutment plate 17. A groove 19 for the connecting rod 18 to slide is provided on the side wall of the movable plate 13, and a connecting ring 20 is fixedly connected to the side wall of the movable plate 13, and the connecting ring 20 and the abutment plate 17 are connected by a spring 21. When the mounting frame 3 and the abutment plate 1 When the mounting frame 3 and the mounting bracket 2 need to be installed with each other, the mounting frame 3 is inserted into the mounting bracket 2, and the mounting frame 3 and the side walls of the abutting plate 17 are driven to contact each other, and then pressure is applied to the mounting frame 3. At this time, the abutting plate 17 is affected by the inclined surfaces on both sides and begins to move toward the moving plate 13, and at the same time, the spring 21 is driven to deform and compress. The elastic potential energy released by the spring 21 can drive the abutting plate 17 and the side walls of the mounting frame 3 to abut against each other. When the position of the mounting frame 3 needs to be adjusted, the screw 16 is driven to rotate, and at the same time, the screw 16 drives the moving plate 13 to move along the slide groove 14. At this time, the moving plate 13 drives the mounting frame 3 to move through the fixing member, thereby achieving the effect of adjusting the position of the mounting frame 3.
[0038] like Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, the positioning assembly includes a limit plate 22 slidably connected to the printing platform 4, and fixed plates 23 are fixedly connected on both sides of the limit plate 22. The two fixed plates 23 and the side walls of the printing platform 4 fit each other, and one of the fixed plates 23 and the printing platform 4 are connected by a limit member, and the limit member includes a through groove 24 opened on the side wall of one of the fixed plates 23, and a rotating plate 25 is rotatably connected to the side wall of the through groove 24, and an anti-skid layer 26 is fixedly connected to the side wall of the rotating plate 25. When the anti-skid layer 26 and the side wall of the printing platform 4 abut against each other, the rotating plate 25 and the through groove 24 are clamped with each other. After the printing material is fixed to the rotating frame 6 and the L-shaped plate 5, the clamping of the rotating plate 25 and the through groove 24 is cancelled, and the rotating plate 25 is driven to rotate, and at the same time, the anti-skid layer 26 and the side wall of the printing platform 4 are cancelled. At this time, the limit plate 22 loses its restriction and can be on the printing platform The printing platform 4 is moved on the printing platform 4, and at the same time, the side wall of the limiting plate 22 is driven to fit with the edge of the substrate, and then the rotating plate 25 is driven to rotate and engage with the through groove 24. At this time, the anti-skid layer 26 and the printing platform 4 are in contact with each other. At this time, the limiting plate 22 is affected by the friction between the anti-skid layer 26 and the printing platform 4, so that the limiting plate 22 cannot move on the printing platform 4. When the substrate on the printing platform 4 needs to be replaced, the restriction on the substrate is cancelled by rotating the frame 6 and the L-shaped plate 5, and it is taken out, and then the replaced substrate and the side wall of the limiting plate 22 are brought into contact with each other, and then the substrate is clamped again by rotating the frame 6 and the L-shaped plate 5. At this time, the replaced substrate is affected by the limiting plate 22, so that the position of the replaced substrate is consistent with that of the substrate before replacement, thereby achieving the effect of positioning the substrate.
[0039] like Figure 3 , Figure 4 As shown, the side of the screw rod 16 away from the fixed frame 15 is fixedly connected to the knob 27, and the side wall of the knob 27 is fixedly connected to the limit ring 9. The side wall of the fixed frame 15 is provided with an annular groove 10 for the limit ring 9 to rotate, which can facilitate the screw rod 16 to rotate and prevent the screw rod 16 from separating from the fixed frame 15.
[0040] The working principle of the utility model is as follows: when using a screen printing machine to print a substrate, the printing plate and the mounting frame 3 are mounted on each other, and then the mounting frame 3 and the mounting frame 2 are mounted on each other, and then the substrate is placed on the printing platform 4, and at the same time, a pulling force is applied to the rotating frame 6, driving the clamping block and the clamping slot to cancel the clamping connection and separate from each other, and at the same time, the torsion spring 12 loses its restriction and begins to deform and recover, and drives the rotating frame 6 to rotate upward, and then the substrate is placed on the L-shaped plate 5, and then the rotating frame 6 is driven to rotate downward, and the rotating frame 6 is driven to rotate downward, and at the same time, the rotating frame 6 and the bottom of the L-shaped plate 5 are driven to fit each other, and the clamping block is driven to enter the clamping slot and clamp with the clamping slot. At this time, the substrate Affected by the L-shaped plate 5 and the rotating frame 6, the printing material is clamped and fixed by the L-shaped plate 5 and the rotating frame 6, and then the rotating plate 25 and the through slot 24 are driven to cancel the clamping, and the rotating plate 25 is driven to rotate. At the same time, the anti-skid layer 26 and the side wall of the printing platform 4 are canceled. At this time, the limiting plate 22 loses its restriction and can move on the printing platform 4. At the same time, the side wall of the limiting plate 22 is driven to fit the edge of the printing material, and then the rotating plate 25 is driven to rotate and clamped with the through slot 24. At this time, the anti-skid layer 26 and the printing platform 4 are in contact with each other. At this time, the limiting plate 22 is affected by the friction between the anti-skid layer 26 and the printing platform 4, so that the limiting plate 22 cannot move on the printing platform 4.
[0041] After the substrate is fixed, the mounting frame 2 is driven by the machine body 1 to move the mounting frame 3 downward and continue to apply pressure, and then the screw 16 is driven to rotate, and the screw 16 drives the movable plate 13 to move along the slide groove 14. At this time, the movable plate 13 drives the mounting frame 3 to move through the fixing part. When the positioning groove 8 moves to be aligned with the position of the positioning block 7, the positioning block 7 is inserted into the positioning groove 8, and the printing plate and the substrate are driven to contact each other, and then the ink is poured onto the printing plate, and the ink is spread with a scraper. At this time, the ink will print the pattern onto the substrate through the printing plate, thereby completing the printing of the substrate.
[0042] When it is necessary to print the substrates in batches, the mounting frame 2 is lifted upwards through the machine body 1, and then the L-shaped plate 5 and the rotating frame 6 are driven to cancel the clamping, and then the substrate is taken out and replaced. When replacing, the restriction on the substrate is cancelled by the rotating frame 6 and the L-shaped plate 5, and it is taken out, and then the replaced substrate and the side wall of the limiting plate 22 are brought into contact with each other, and then the substrate is clamped again by the rotating frame 6 and the L-shaped plate 5. At this time, the replaced substrate is affected by the limiting plate 22, so that the position of the replaced substrate can be kept consistent with that of the substrate before replacement, and then the above operation is repeated to print the substrate, so as to avoid the problem of deviation in the position of the substrate and improve the printing effect during batch printing.
