Description

Technical Field

[0001] This utility model relates to the technical field of fire extinguisher processing equipment, specifically a fire extinguisher screen printing equipment. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool consisting of a cylinder, head, nozzle, and other components. It uses driving pressure to spray out a filled extinguishing agent. Fire extinguishers contain chemicals and are used to extinguish fires. They are common fire-fighting equipment, stored in public places or areas where fires may occur. Different types of fire extinguishers contain different components and are designed for different types of fires. Commonly used fire extinguishers include foam, dry powder, acid / alkali, CO2, and 1211 types. Because they require spraying their contents to extinguish fires, care must be taken when using them to avoid adverse effects and potential dangers.

[0003] After fire extinguishers are manufactured, in addition to the necessary fixed text and image labels, they also need to be printed with labels that vary according to specifications and types. However, the existing printing equipment requires manual loading, and the loading space is also relatively small because the vertical travel of the printing plate holder is small. This not only increases the difficulty of loading and unloading operations but also reduces processing efficiency, indicating room for further improvement. Utility Model Content

By keeping the position of the fire extinguisher valve in a downward direction, the initial printing position is guaranteed. At the same time, the bottle body rotation mechanism is easy to install, and different bottle body rotation mechanisms can be selected according to the bottle size. This prevents the printing position from being on the roller contact surface, which would affect the printing film, and improves flexibility.

[0022] 3. This utility model sets up a rapid drying device on the outer side of the middle of the discharge table, and then connects it with a printing device for rapid secondary printing to form a rapid secondary printing production line.

[0031] Example 1:

[0032] like Figure 1-5As shown, this utility model embodiment provides a screen printing device for fire extinguishers, including a main frame 1, a feeding platform 2, and a discharging platform 3.

The lengths of the first rotating shaft 232 and the second rotating shaft 233 correspond to the specifications of the fire extinguisher bottle. Different bottle rotating mechanisms 23 can be selected according to the bottle specifications to prevent the printing position from being on the contact surface of the roller 238 and affecting the printing film.

[0034] The mounting base 231 is rotatably connected to the upper sides of the first rotating shaft 232 and the second rotating shaft 233 respectively.

A position sensor 26 is set on the third bottle transport rack 4 station at the end of the feeding platform 2 closest to the main frame 1. A bottle adjustment seat 5 is fixedly connected to the outside of the fourth bottle transport rack 4 station at the end of the feeding platform 2 closest to the main frame 1. A second adjustment power cylinder 25 is set above the bottle adjustment seat 5 for preliminary adjustment of the axial position of the fire extinguisher bottle.

[0037] Both sides of the support base 13 are slidably connected to transverse slides 14 via slide rails. Both ends of the two transverse slides 14 are fixedly connected to lifting support seats 15. The four lifting support seats 15 are slidably connected to bottle transfer supports 17. The lower interior of the four lifting support seats 15 is fixedly connected to lifting power cylinders 16. The upper output ends of the multiple lifting power cylinders 16 are fixedly connected to the corresponding bottle transfer supports 17. The four lifting power cylinders 16 move synchronously. The two transverse slides 14 are respectively located on the outer sides of the bottle transport frame 4, and the distance between the two ends of the two transverse slides 14 is half of the sliding stroke. During operation, loading and unloading can be performed simultaneously at both ends through a lifting action.

[0038] Both sides of the support base 13 are rotatably connected to end gears 30. Both sides of the support base 13 are respectively meshed with synchronous toothed belts 28 by two end gears 30. A drive motor 29 is set in the middle of the end of the support base 13 near the feed table 2. The two synchronous toothed belts 28 are respectively fixedly connected to the two ends of the corresponding transverse slide table 14 after passing under the slide rail of the support base 13. The output end of the drive motor 29 is provided with a worm gear structure, and the two ends of the worm are respectively fixedly sleeved with the two end gears 30 near the end of the feed table 2. The drive motor 29 can drive the corresponding synchronous toothed belts 28 to move synchronously by synchronously driving the end gears 30.

[0039] Example 2:

[0040] like Figure 6As shown, this embodiment differs from Embodiment 1 in that the structure of the discharge platform 3 is the same as that of the feed platform 2, a position sensor 26 and a second adjusting power cylinder 25 are added, and a printing device of this invention is connected in series with the discharge platform 3. At the same time, a rapid drying device is set on the outer side of the middle of the discharge platform 3, which can form a rapid secondary printing production line. By rapidly drying the printing film, the waiting time for secondary printing is greatly reduced. Similarly, after adding and arranging the discharge platform 3 and the equipment in sequence, multiple printings can be performed without stacking the fire extinguisher bottles and waiting for the printing film to dry before secondary printing. This not only improves printing efficiency but also reduces the resource occupation of warehousing and logistics, thereby improving production efficiency.

[0041] Working Principle: In operation, the fire extinguisher bottle is first initially axially adjusted by the first adjusting power cylinder 24 on the feeding platform 2. Then, through the cooperation of the lifting support 15 and the bottle transfer support 17, the bottle is lifted from the feeding platform 2 to the bottle rotation mechanism 23 by the transverse slide 14. At the same time, the lifting support 15 and the bottle transfer support 17 at the other end unload the printed bottle from the bottle rotation mechanism 23 and place it on the discharge platform 3 for discharge. The position of the fire extinguisher valve handle is then determined by the adjusting sensor 27. The angle of the fire extinguisher bottle can be adjusted by cooperating with the bottle rotation mechanism 23 to keep the fire extinguisher valve in a downward direction, ensuring the determination of the initial printing position. After the bottle position is adjusted, the lifting scraper 12 descends to abut against the printing plate, and at the same time, the main lifting seat 6 also descends to abut against the bottle. Then, the printing plate slides laterally through the roller brush slide, and the bottle rotates synchronously through the bottle rotation mechanism 23 to complete the printing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
