[0005] The purpose of the utility model is to address the deficiencies in the prior art and to provide a double-sided printing positioning detection device for a screen printing machine. The device realizes the function of clamping the printed part by driving the spring and the sliding part when the lead screw drives the slider to move, by means of a clamping plate structure arranged on both sides of the top end surface of a fastening seat and cooperating with a spring and a sliding part structure in a slider, thereby solving the problem of fixed damage to the printed part caused by the inability to adjust the clamping force.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A double-sided printing positioning and detection device for a screen printing machine, including a base, fastening seats and a printing machine main body fixed on both sides of the top surface of the base. A printing piece is arranged on the top of the fastening seat, and sliding grooves are opened on both sides of the top surface of the fastening seat. Sliders are slidably inserted into both of the two sliding grooves. Clamping plates are arranged on both sides of the top surface of the fastening seat. An expansion slot is opened on the side wall of the slider, and a sliding portion slidably inserted into the expansion slot is arranged at the bottom end of the clamping plate. A spring is embedded and installed in the expansion slot, and electrode plates are embedded and fixed on the inner wall of the expansion slot and the sliding portion respectively.

[0007] Preferably, a screw rod is rotatably installed between the two sliding grooves, and opposite ends of the screw rod with opposite thread directions are respectively threadedly inserted into the two sliders.

[0008] Furthermore, both ends of the screw rod are rotatably inserted into the fastening seat through bearings, and a knob is fixedly installed at one end of the screw rod extending out of the fastening seat.

[0024] Embodiment 1

[0025] As Figure 1 and Figure 2 shown, this embodiment provides a double-sided printing positioning and detection device for a screen printing machine, including a base 1, and fastening seats 3 and a printing machine main body 9 fixed on both sides of the top surface of the base 1. A printing piece 2 is arranged at the top of the fastening seat 3, and sliding grooves 13 are opened on both sides of the top surface of the fastening seat 3. Sliders 10 are slidably inserted into both of the two sliding grooves 13. Among them, clamping plates 5 are arranged on both sides of the top surface of the fastening seat 3. An expansion slot 17 is opened on the side wall of the slider 10, and a sliding part 14 slidably inserted into the expansion slot 17 is arranged at the bottom end of the clamping plate 5. A spring 18 is embedded and installed in the expansion slot 17, and electrode plates 19 are embedded and fixed on the inner wall of the expansion slot 17 and the sliding part 14.

[0026] A screw rod 11 is rotatably installed between the two sliding grooves 13. The two ends with opposite thread directions of the screw rod 11 are respectively threadedly inserted into the two sliders 10. Both ends of the screw rod 11 are rotatably inserted into the fastening seat 3 through bearings, and a knob 4 is fixedly installed at one end of the screw rod 11 extending out of the fastening seat 3. An electric push rod 8 is installed on the side wall of the printing machine main body 9, and a brush plate 7 is fixed on the electric push rod 8. A screen main body 6 is fixedly installed on the top of the base 1. The brush plate 7 is slidably arranged on the top of the screen main body 6. During the process of the knob 4 driving the screw rod 11 to rotate, the two sliders 10 move towards each other, and during the movement, the clamping plates 5 are driven to move synchronously through the spring 18 and the sliding part 14. After the clamping plates 5 are in contact with the side wall of the printing piece 2, they are fixed, and after being fixed, they continue to move by stretching the spring 18 fixed to the adjusting plate 15. The extrusion force between the sliding part 14, the clamping plate 5 and the side wall of the printing piece 2 is increased through the deformation force of the spring 18, and the extrusion force for fixing the printing piece 2 is adjusted by adjusting the deformation degree of the spring 18.

[0027] Embodiment 2

[0028] As Figure 3 and Figure 4 shown, where the same or corresponding components as those in Embodiment 1 are provided with the corresponding reference numerals in the drawings of Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 2 and Embodiment 1 lies in that indicator lights 12 are installed on both sides of the top end surface of the clamping plate 5, and both electrode plates 19 are electrically connected to the indicator lights 12. An adjusting plate 15 is slidably inserted into the telescopic groove 17. Both ends of the spring 18 are fixedly connected to the adjusting plate 15 and the sliding part 14 respectively. A bolt 16 is threadedly inserted into the side wall of the slider 10. One end of the bolt 16 extending into the telescopic groove 17 is rotatably inserted into the adjusting plate 15. By rotating the bolt 16, the position of the adjusting plate 15 is adjusted, thereby adjusting the elastic force of the spring 18. And by installing electrode plates 19 on both the inner wall of the telescopic groove 17 and the sliding part 14, when the spring 18 is stretched and deformed, the sliding part 14 slides in the telescopic groove 17. When the electrode plates 19 on the telescopic groove 17 and the sliding part 14 come into contact with each other, the indicator light 12 is activated to detect the stretching stroke of the spring 18.

[0029] Working steps

[0030] Step 1: When in use, during the process of holding the knob 4 and driving the screw 11 to rotate, the two sliders 10 move towards each other, and during the movement, the clamping plate 5 is driven to move synchronously through the spring 18 and the sliding part 14. After the clamping plate 5 abuts against the side wall of the printed part 2, it remains fixed. And after being fixed, it continues to move by stretching the spring 18 fixed to the adjusting plate 15. The squeezing force between the sliding part 14, the clamping plate 5 and the side wall of the printed part 2 is increased through the deformation force of the spring 18. By adjusting the degree of deformation of the spring 18, the squeezing force for fixing the printed part 2 is adjusted, avoiding the situation that the printed part 2 is deformed due to the unadjustable squeezing force. By rotating the bolt 16, the position of the adjusting plate 15 is adjusted, thereby adjusting the elastic force of the spring 18. And by installing electrode plates 19 on both the inner wall of the telescopic groove 17 and the sliding part 14, when the spring 18 is stretched and deformed, the sliding part 14 slides in the telescopic groove 17. When the electrode plates 19 on the telescopic groove 17 and the sliding part 14 come into contact with each other, the indicator light 12 is activated to detect the stretching stroke of the spring 18, avoiding the situation that the squeezing force is too large due to the over-stretching of the spring 18.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
