Description

Technical field:

[0001] The invention relates to the technical field of spraying machines, in particular to a high-efficiency portable plunger spraying machine. Background technology:

[0002] In the field of spraying equipment, traditional sprayers have exposed many significant limitations. First of all, their large size has become a major obstacle in practical applications. In small decoration scenes such as partial repair of indoor walls in homes, as well as in working environments such as renovation of street shop facades and maintenance of outdoor facilities, traditional sprayers often bring great difficulties to the handling work because they are difficult to pass through narrow aisles, stairs and other spaces smoothly, which fully highlights their serious lack of portability. At the same time, there is also a lot of room for improvement in the work efficiency of traditional sprayers. Especially in scenes such as large-scale building decoration treatment with high precision requirements, it is impossible to accurately control the ratio of the two coatings according to actual needs. This situation is very likely to lead to waste of materials, because inappropriate ratios may prevent the coating from fully exerting its role, and some coatings may be discarded without being reasonably used. Moreover, inappropriate coating ratios can also cause unsatisfactory spraying effects, such as uneven coating thickness and inconsistent colors, which seriously affect the final quality of the product. The existence of these problems makes traditional sprayers appear to be powerless in the face of increasingly diversified and refined spraying needs, and there is an urgent need for a more advantageous spraying equipment to meet market demand.

[0028] The use status of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost and convenient installation. When in use, the sprayer is first pushed to the position where the spraying operation is required through the wheels 2 on the mounting base 1, and the operator can hold the handle 3 to control the moving direction and position of the sprayer, thereby improving the portability during use, and then according to the operation requirements, check whether the plunger device 1 7 and the plunger device 2 9 in the placement box 6 and the components connected thereto are normally installed and connected, ensure that the inlet of the output pipe 8 is firmly connected to the outlet of the plunger device 1 7 and the plunger device 2 9, and the other end of the output pipe 8 is connected to the corresponding interface of the spray gun or spraying equipment (assuming that the subsequent equipment such as the spray gun needs to be connected, the specific subsequent equipment is not explicitly mentioned here and can be supplemented according to the actual situation). The motor 51 is turned on (the motor 51 can be a servo motor or a variable frequency motor, and the appropriate motor type can be selected according to the specific operation accuracy and speed requirements). The motor 51 drives the turntable 52 to rotate, and the fixed shaft 1 53 on the right edge of the turntable 52 makes a circular motion with the turntable, and the fixed shaft 1 53 moves in the connecting long groove 54, thereby driving the slider 55 to make a longitudinal reciprocating motion in the sliding cavity 56.

The central outer side of the adjusting head 522 is provided with an inner hexagonal hole, which can be adjusted using corresponding tools (such as an inner hexagonal wrench). By rotating the adjusting head 522, the screw rod 521 is driven to rotate in the guide groove 517, so that the movable seat 515 moves laterally in the guide groove 517, thereby changing the swing amplitude and frequency of the swing arm 510, and then adjusting the plunger device one 7 and the plunger device two 9.

Here, the output pipe 8 is a three-way hose, which can evenly transport the paint to the subsequent spraying equipment (such as a spray gun) for spraying. The paint is atomized at the spray gun and sprayed onto the surface of the object to be coated to complete the spraying work. During the entire use process, the mounting seat 1, wheels 2, handles 3 and other components provide convenience for the movement and operation of the sprayer. The outer shell 4 protects the internal adjustable output mechanism 5 and other components.
