Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, and in particular to an adjustable screen fixing device for screen printing machines. Background Technology

[0002] Screen printing, as a widely used printing technology, plays a crucial role in many fields. As the core equipment in screen printing, the performance and functionality optimization of the screen printing machine are essential for improving printing quality and efficiency. The screen fixing device, as a vital component of the screen printing machine, directly affects the stability and accuracy of the screen during the printing process.

[0003] Currently, there are various screen printing machine screen fixing devices on the market. For example, some traditional fixing devices use bolt fastening, which connects the screen frame to the screen printing machine frame by bolting through threaded holes.

[0004] However, this method requires operators to tighten or loosen bolts one by one using tools when installing and removing the screen, which is cumbersome and time-consuming, seriously affecting work efficiency. Moreover, during long-term use, the bolts are prone to loosening due to vibration and other reasons, resulting in the screen not being firmly fixed and displacement during the printing process, which in turn affects the accuracy and quality of the printed pattern. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable screen fixing device for screen printing machines, so as to solve the problems of cumbersome operation, poor adaptability to screen frames of different sizes, and unstable screen fixing in the existing screen fixing devices for screen printing machines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable screen printing machine screen fixing device, comprising a horizontally arranged support base, a movable base, two support plates, and two connecting arms. Side plates are provided on both sides of the support base, and at least two optical rods extending along the X-axis are connected between the two side plates. A rack extending along the X-axis is provided on the inner side of the support base. Sliding pairs, the same number as the optical rods, are provided on both sides of the bottom surface of the movable base, and the movable base is slidably connected to each optical rod through the sliding pairs. An adjusting gear is rotatably mounted on the bottom of the movable base, meshing with the rack. An adjusting drive motor is provided on the top surface of the movable base. The transmission is connected to the adjusting gear; two support plates are fixedly installed on both sides of the movable seat. The inner side of the support plate is provided with a Y-axis adjusting groove extending along the Y-axis direction. A Y-direction locking rod is threaded onto the support plate, and the inner end of the Y-direction locking rod extends to the Y-axis adjusting groove. The outer side of the two connecting arms is formed with a Y-direction connecting part. The connecting arm is slidably connected to the Y-axis adjusting groove through the Y-direction connecting part. The inner end of the Y-direction locking rod contacts the Y-direction connecting part to lock the position of the connecting arm along the Y-axis direction. The inner side of the connecting arm is provided with a slot. The slots of the connecting arms on both sides cooperate to engage the wire mesh tray. The wire mesh tray includes a frame and a wire mesh. The two sides of the frame of the wire mesh tray are respectively engaged with the slots of the corresponding connecting arms.

[0007] In a further technical solution, through pin holes are provided on both sides of the frame of the wire mesh reel; the slot is provided with through holes that pass through its cavity from top to bottom, and a pin is movably inserted into the through hole. The pin is also connected in series with the corresponding pin hole to lock the wire mesh reel.

[0008] In a further technical solution, multiple positioning lock holes are provided on both sides of the movable seat, and the positioning lock holes on the same side are arranged in an array; a connecting plate is provided on the inner side of the support plate, and the connecting plate is connected to the corresponding positioning lock hole by at least two bolts to realize the position of the support plates on both sides in the X-axis or Y-axis.

[0009] In a further technical solution, two light rods are set, including a first light rod and a second light rod. The first light rod is located inside the second light rod, and the height of the first light rod is lower than that of the second light rod.

[0010] In a further technical solution, the distance between the first optical rod and the second optical rod along the Y-axis is not less than 15cm.

[0011] In a further technical solution, distance sensors are respectively provided on the inner sides of the two side plates. The distance sensors detect the action on the side of the movable seat. The wire mesh fixing device also includes a control circuit. The distance sensors and the adjustment drive motor are electrically connected to the control circuit. The distance sensors on both sides collect the interval distance between the movable seat and the side plates on both sides and send it to the control circuit. The control circuit controls the adjustment drive motor to rotate forward or backward to realize the electronic control adjustment of the wire mesh disc in the X-axis direction.

[0012] The advantages of this invention compared to the prior art after adopting the above structure are: 1. The movable seat can be precisely adjusted along the X-axis by means of a rack and pinion mechanism and a sliding pair of guide rods; at the same time, the position of the connecting arm in the Y-axis direction can be flexibly adjusted by using the Y-axis adjustment groove and Y-axis locking rod. This bidirectional adjustment mechanism allows the device to be adapted to wire mesh reels of different sizes, significantly improving the versatility of the equipment.

[0013] 2. The combination design of the slot and the pin rod makes it possible to install and remove the wire mesh reel without the aid of tools. It can be fixed by simply snapping it in and inserting the pin, which greatly shortens the screen changing time and improves production efficiency.

[0014] 3. The design of double smooth rods with staggered heights effectively increases the support span, reduces the risk of lateral displacement of the movable seat during sliding, and improves the overall structural rigidity and movement stability.

[0015] 4. The integrated distance sensor and control circuit can monitor the position of the movable seat in real time and automatically control and adjust the drive motor to realize closed-loop electronic control adjustment of the X-axis position of the wire mesh, reduce manual intervention, and improve adjustment accuracy and consistency.
