Description

Technical Field

[0001] This utility model relates to the field of construction site fencing printing technology, specifically a positioning device for printing construction site fencing. Background Technology

[0002] Construction site fencing is a facility used to isolate a construction site from the external environment. Its main purpose is to protect the safety and cleanliness of the construction site while minimizing its impact on the surrounding environment. Fencing is typically constructed from various masonry materials or prefabricated panels, effectively separating the construction area from the external environment and preventing noise and dust generated during construction from affecting the lives of nearby residents. During the production process, reflective strips and other patterns are printed on the surface of the fencing panels to enhance its aesthetics and safety.

[0003] A search revealed patent application CN202022313486.8, which discloses a portable printing plate device. The device includes a support plate, a motor, and rollers. A first rotating shaft is rotatably mounted on the top front of the support plate, and a first roller is fixedly connected to the outer wall of the first rotating shaft. A conveyor belt is rotatably connected to the outer wall of the first roller, and the outer wall of the conveyor belt is fitted with the plate body. This portable printing plate device allows the plate to be placed on the top surface of the conveyor belt. The motor drives a second rotating shaft and a second roller, which in turn drives the conveyor belt to rotate the first roller and the first rotating shaft, thus moving the plate. During this movement, a top-mounted printing press prints on the plate. The printed plate is then moved further by the rotation of the rollers and the internal movable shaft. This facilitates plate movement, reduces the difficulty of printing, streamlines the printing process, improves user efficiency, and provides convenience to the user.

[0004] However, this patent has its shortcomings. The printing device does not have a structure for positioning the printing plate. In actual use, when the printing plate is placed on the conveyor belt and fed into the printing machine, the printing plate is prone to shifting on the conveyor belt, which will cause the subsequent printed pattern to be misaligned with the printing plate and affect the printing quality.

[0005] To address this, we propose a positioning device for printing on construction site fencing. Utility Model Content

A printing machine body 1 is arranged on the left side of the positioning platform 2. An I-beam frame 5 is fixedly installed on the top of the positioning platform 2. A swing arm 7 is rotatably connected to the top of the I-beam frame 5. Both ends of the swing arm 7 are rotatably connected to connecting arms 17. Slides 18 are arranged on the I-beam frame 5 at the front and rear of the swing arm 7. The ends of the two connecting arms 17 away from the swing arm 7 are rotatably connected to the corresponding slides 18. A second positioning plate 19 is arranged on the top of the two slides 18. A fencing plate 9 is clamped and fixed between the two second positioning plates 19. A U-shaped frame 4 is fixedly sleeved on the top of the positioning platform 2 outside the connecting arm 17. A first positioning plate 8 is fixedly installed on the top left side of the U-shaped frame 4. A transmission rod 14 is rotatably connected inside the printing machine body 1. Two gears 15 are fixedly sleeved on the transmission rod 14. Gear racks 13 are fixedly installed on the front and rear ends of the positioning platform 2. The tops of the two gears 15 are respectively meshed and connected to the corresponding gear racks 13.

[0025] Multiple measuring seats 21 are fixedly installed on the two carriages 18 on the opposite sides of the two second positioning plates 19. Pressure sensors 20 are fixedly installed within each measuring seat 21. A pressure plate 22 is slidably connected to the side of each measuring seat 21 away from the pressure sensor 20. A connecting rod 23 is fixedly installed on the side of each pressure plate 22 away from the pressure sensor 20. The end of each connecting rod 23 away from the pressure plate 22 extends out of the measuring seat 21 and is fixedly installed on the corresponding second positioning plate 19. This design facilitates the use of the equipment. A second motor 16 is fixedly installed at the front end of the printing press body 1. The output end of the second motor 16 is fixedly installed on the transmission rod 14. The second motor 16 drives the transmission rod 14 to rotate, which facilitates the use of the equipment. A PLC controller 3 is fixedly installed on the front end of the machine body 1 above the second motor 16. The PLC controller 3 facilitates the control of the equipment. A slot 12 is opened in the positioning table 2 corresponding to the transmission rod 14. The transmission rod 14 is set in the slot 12. This design is beneficial to the use of the equipment. The first motor 6 is fixedly installed on the top of the positioning table 2 below the I-beam 5. The output end of the first motor 6 is fixedly installed on the swing arm 7. The first motor 6 drives the swing arm 7 to rotate, which is beneficial to the use of the equipment. Slide grooves 10 are provided in both output ends of the I-beam 5. Two sliders 11 are fixedly installed at the bottom of each slide 18. Multiple sliders 11 are slidably connected in the corresponding slide grooves 10. The sliders 11 can limit the movement of the slide 18.

[0026] Working principle: During use, the baffle 9 to be printed is placed on the U-shaped frame 4 between the two second positioning plates 19, so that the left end of the baffle 9 abuts against the first positioning plate 8. The positioning switch is turned on. At this time, the first motor 6 works to drive the swing arm 7 to rotate. The swing arm 7 drives the two connecting arms 17 to deflect, so that the two connecting arms 17 pull the two slides 18 toward each other. The two slides 18 drive the two second positioning plates 19 to clamp and position the front and rear ends of the baffle 9 toward each other. During the clamping and fixing of the baffle 9 by the two second positioning plates 19, multiple connecting rods 23 are squeezed into the corresponding measuring seats 21. Pressure is applied to the pressure sensor 20 through the pressure plate 22. When the pressure sensor 20 detects the two second positioning plates 23, the pressure sensor 20 will press the pressure sensor 20. When the clamping pressure of the positioning plate 19 reaches the predetermined value, the first motor 6 stops working immediately to avoid damage to the fence 9 caused by excessive clamping force. Finally, the printing switch is turned on. At this time, the second motor 16 works to drive the transmission rod 14 and the two gears 15 to rotate. Since the two gears 15 are meshed and connected to the rack 13, the rack 13 drives the positioning table 2 to slide to the left and retract into the printing machine body 1 for printing. This positioning device for printing construction site fences is easy to use. The above components can be used to position and calibrate the fence 9 to be printed, avoiding the fence 9 from shifting during transportation and affecting the printing quality. At the same time, the clamping force can be detected during the clamping and positioning of the fence 9 to prevent damage caused by excessive clamping force of the second positioning plate 19.
