Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic plastic spraying, and particularly relates to an electrostatic plastic spraying device that is easy to use. Background Art

[0002] The working principle of electrostatic powder spraying is almost the same as that of general liquid coating electrostatic spraying, except that powder spraying is dispersed rather than atomized. The coating sprayed by the electrostatic powder spray gun makes the powder particles negatively charged while being dispersed. The charged powder particles are affected by airflow (or other forces such as centrifugal force) and electrostatic attraction, and are coated on the grounded object, and then heated, melted and solidified into a film.

[0003] In order to meet market demand, the existing electrostatic spraying devices are generally optimized in terms of how to spray better and how to make it more convenient for users to use them, but whether they can be well monitored is often ignored. The existing electrostatic spraying devices have the advantages of better spraying effect and more convenient for users to use them, but there are certain limitations. In normal use, due to the construction process, most of the powder storage boxes are in a completely sealed state, and the remaining amount of powder inside the powder storage box cannot be clearly viewed, causing construction interruption.

[0004] The existing technology has the problem that the internal margin cannot be clearly seen, so an easy-to-use electrostatic spraying device is proposed to solve the above problem. Utility Model Content

[0006] To achieve the above purpose, the specific technical scheme of the utility model is as follows: an easy-to-use electrostatic spraying device, comprising a lifting spraying frame for spraying and a storage box for storing spraying supplies, the top of the storage box is used in conjunction with the bottom of the lifting spraying frame, the bottom of the storage box is provided with a positioning frame, and the interior of the storage box is provided with a measuring component;

[0007] The measuring assembly includes a weight plate, the outer surface of which is slidably connected to the inner wall of the storage box, extrusion springs are fixedly installed on the left and right sides of the bottom of the weight plate, one end of the extrusion spring away from the weight plate is fixedly connected to the bottom of the inner wall of the storage box, an observation rod is fixedly installed on the top of the weight plate, the top of the observation rod passes through the storage box and extends to the top of the storage box, a limiting column is fixedly installed on the top of the weight plate, the limiting column is located on the left side of the observation rod, and scale lines are opened on the outer surface of the observation rod.

[0008] Preferably, a protective sleeve is provided on the outer surface of the extrusion spring, the top of the protective sleeve is fixedly connected to the bottom of the weight plate, and the bottom of the protective sleeve is fixedly connected to the bottom of the inner wall of the storage box.

[0009] Preferably, a limiting block is fixedly mounted on the top of the observation rod, and the bottom of the limiting block is in contact with the top of the storage box.

[0010] Preferably, a square ring-shaped sealing block is fixedly mounted on the outer surface of the weight plate, and the outer surface of the square ring-shaped sealing block is in contact with the inner wall of the storage box and is slidably connected thereto.

[0011] Preferably, a collecting mechanism is provided inside the lifting spraying frame, and the collecting mechanism includes a plug-in slot, which is opened inside the lifting spraying frame, a plug-in block is plugged into the plug-in slot, and an L-shaped collecting plate is fixedly installed on the bottom of the plug-in block.

[0014] The utility model has the following advantages:

[0015] 1. This easy-to-use electrostatic spraying device uses manpower to add electrostatic powder to the inside of the storage box through the filling port.

While pressing, a deformation force is given to the extrusion spring, and the observation rod is driven down at the same time. After filling, the spraying work can be started.

The outer surface of the observation rod 6 is provided with a scale line 8, and the electrostatic powder is manually fed through the filling port. Fill the storage box 2 with powder. While filling, the powder falls on the weight plate 4. The weight plate 4 is pressed downward by the weight of the powder itself. While pressing, the extrusion spring 5 is given a deformation force, which drives the observation rod 6 to descend. After it is filled, the spraying work can be started. During work, because the force is mutual, as the powder decreases, the extrusion spring 5 also gives the weight plate 4 the same reaction force, so that the observation rod 6 can be lifted up. During the lifting process, the remaining amount of powder can be seen intuitively, which makes the spraying effect better.

[0029] The outer surface of the extrusion spring 5 is covered with a protective cover 9, the top of the protective cover 9 is fixedly connected to the bottom of the weight plate 4, and the bottom of the protective cover 9 is fixedly connected to the bottom of the inner wall of the storage box 2. By providing the protective cover 9, which is also covered on the outer surface of the extrusion spring 5, the extrusion spring 5 can be protected and the service life of the extrusion spring 5 can be extended.

[0030] A limiting block 10 is fixedly installed on the top of the observation rod 6, and the bottom of the limiting block 10 is in contact with the top of the storage box 2.

[0032] Example 2

[0033] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 6 A collecting mechanism is provided inside the lifting spray rack 1, and the collecting mechanism includes a plug-in slot 12, and the plug-in slot 12 is opened inside the lifting spray rack 1, and a plug-in block 13 is plugged into the plug-in slot 12. An L-shaped collecting plate 14 is fixedly installed at the bottom of the plug-in block 13. By setting the plug-in slot 12 and plugging the plug-in block 13 inside, the L-shaped collecting plate 14 can be positioned, so that the collection effect is better.

By setting the pulling handle 18, the pulling effect of the strip cleaning block 17 can be better, and the cleaning effect can be better.

[0036] The working principle of the easy-to-use electrostatic spraying device is as follows: first, electrostatic powder is filled into the storage box 2 through the filling port by manpower. While filling, the powder falls on the weight plate 4, and the weight plate 4 is pressed downward by the weight of the powder itself. While pressing, a deformation force is given to the extrusion spring 5, and the observation rod 6 is driven down at the same time. After the filling is full, the spraying work can be started. During work, because the force is mutual, as the powder decreases, the extrusion spring 5 also gives the weight plate 4 the same reaction force, so that the observation rod 6 can be lifted up. During the lifting process, the remaining amount of powder can be seen intuitively, so that the spraying effect is better. Secondly, by setting the plug-in slot 12 and using the plug-in block 13 inside, the positioning of the L-shaped collecting plate 14 can be achieved, so that the sprayed powder can be recovered, so that the collection effect is better. After the work is completed, the pulling handle 18 is pulled by manpower to drive the strip cleaning block 17 to move on the L-shaped collecting plate 14, so that good cleaning can be achieved.
