Description

Technical Field

[0001] The invention belongs to the technical field of spraying, and in particular relates to a double-gun multi-surface spraying system. Background Art

[0002] Paint refers to the material coated on the surface of the object to be protected or decorated, which can form a continuous film that is firmly attached to the coated object and has a certain strength. Sometimes, all four sides of the object to be sprayed need to be sprayed with paint. For example, fire retardant paint is sprayed on the four sides of a four-sided steel column indoors to ensure the fire resistance of the steel column. At present, most of the existing mechanisms for spraying four-sided steel columns use a single spray gun spray system, which uses a lifting mechanism to drive the spray system to spray the four spraying surfaces of the spraying object. Since a single spray gun is used, the position of the entire equipment will be adjusted every time the spraying of the spraying surface is completed, which is troublesome to operate and has low spraying efficiency.

DETAILED DESCRIPTION

[0024] In order to solve the problem of low spraying efficiency of a single spray gun, the present invention provides a dual-gun multi-surface spraying system. The dual-gun multi-surface spraying system is further described below with reference to specific embodiments and accompanying drawings.

[0025] See also Figure 1 to Figure 6 As shown, a double-gun multi-surface spraying system 4 is connected to a lifting mechanism 2, comprising:

[0026] two spray gun assemblies 403;

[0027] Two swing arm assemblies are used to realize the swing positioning of two spray gun assemblies 403 on the horizontal plane respectively, and the two swing arm assemblies are symmetrically arranged on the same side of the lifting mechanism 2; the swing arm assembly includes a main arm 401 and a secondary arm 402, one end of the main arm 401 is pivoted to one end of the secondary arm 402, and the other end of the main arm 401 is pivoted to the lifting mechanism 2, and the two spray gun assemblies 403 are respectively installed on the opposite inner sides of the two secondary arms 402, and the pivot axis between the main arm 401 and the secondary arm 402 is parallel to the pivot axis between the main arm 401 and the lifting mechanism 2; the secondary arm 402 has at least a first swing axis relative to the main arm 401 When the two main arms 401 are swung to a certain angle and the two auxiliary arms 402 are swung to the corresponding first swing position, the two spray gun assemblies 403 are respectively oriented to the first group of two adjacent surfaces on the object to be sprayed, and when the two auxiliary arms 402 are swung to the corresponding second swing position, the two spray gun assemblies 403 are respectively oriented to the second group of two adjacent surfaces on the object to be sprayed; wherein, there are four surfaces to be sprayed of the object to be sprayed, the first group of two adjacent surfaces refers to the two adjacent surfaces of the object to be sprayed, and the second group of two adjacent surfaces refers to the remaining two adjacent surfaces of the object to be sprayed;

[0028] Two first locking members 405 for locking the two main arms 401 to the lifting mechanism 2 when the two main arms 401 swing to a certain angle, and are respectively arranged between the two main arms 401 and the lifting mechanism 2;

[0029] Two first fasteners 404 for respectively locking the two auxiliary arms 402 to the corresponding first swing position or the second swing position are respectively disposed between the corresponding main arm 401 and the auxiliary arm 402 .

[0030] For details, see Figure 1 As shown, the lifting mechanism 2 is arranged on the top of the mobile device 1, and is used to drive the double-gun multi-surface spraying system 4 of the present invention to be lifted and lowered; the present invention adopts a double spray gun design, which can spray paint on two adjacent sides of the object to be sprayed at the same time, thereby improving the spraying efficiency; and then by adjusting the rotation of the two auxiliary arms 402, so that the two spray guns 4037 on the two auxiliary arms 402 are respectively facing the other two sides of the object to be sprayed, multi-surface spraying of the object to be sprayed can be achieved without moving the position of the entire equipment, and the operation is simple and the construction efficiency is high.

[0031] Among them, the certain angle is 90°, the main arm 401 and the corresponding auxiliary arm 402 are arranged one above and one below, when the auxiliary arm 402 swings to overlap with the corresponding main arm 401, it is the first swing position of the auxiliary arm 402, and when the auxiliary arm 402 swings to the relative inner side and is perpendicular to the main arm 401, it is the second swing position of the auxiliary arm 402.

[0032] By designing the two main arms 401 to have an included angle of 90°, the included angle of the two auxiliary arms 402 overlapping the two main arms 401 can also be 90°, which can adapt to the two surfaces to be sprayed that are perpendicular to the steel column. By swinging the auxiliary arm 402 to form a 90° angle with the corresponding main arm 401, it can adapt to the other two surfaces of the steel column, which is beneficial to the spraying construction.

[0033] The dual-gun multi-surface spraying system 4 further includes two moving assemblies (not shown in the figure) respectively mounted on the two auxiliary arms 402, and used to respectively drive the two spray gun assemblies 403 to move along the axial direction of the corresponding two auxiliary arms 402;

[0034] The moving assembly includes a first motor fixed on the corresponding auxiliary arm 402, a first lead screw rotatably connected to the auxiliary arm 402 and fixedly connected to the output shaft of the first motor, and a slider threadedly sleeved on the outside of the first lead screw and connected to the corresponding spray gun assembly 403. The length direction of the first lead screw is consistent with the length direction of the corresponding auxiliary arm 402; the first motor drives the first lead screw to rotate, so as to drive the slider to drive the spray gun assembly 403 to move along the length direction of the corresponding auxiliary arm 402.

[0035] By starting the first motor to drive the first screw to rotate, the slider is driven to move along the length direction of the screw, and then the corresponding spray gun assembly 403 is driven to move along the length direction of the auxiliary arm 402 to adjust the position of the spray gun assembly 403. This can achieve horizontal reciprocating spraying construction on a certain area of ​​the spray surface to be sprayed, and the spraying effect is good.

[0036] The spray gun assembly 403 includes a spray gun 4037 and an adjustment assembly for adjusting the angle of the spray gun 4037 on a vertical plane, and the adjustment assembly is connected between the spray gun 4037 and the moving assembly;

[0037] Specifically, the adjustment component includes a second motor 4032 connected to the slider through a base plate 4031 and a connecting piece connected between the output shaft of the second motor 4032 and the spray gun 4037. The second motor 4032 drives the connecting piece to deflect on the vertical plane to drive the spray gun 4037 to adjust the angle.

[0038] Furthermore, the connecting member includes a first rotating arm 4033 whose first end is connected and fixed to the output shaft of the second motor 4032, a third motor 4034 fixed to the second end of the first rotating arm 4033, a second rotating arm 4035 whose first end is connected and fixed to the output shaft of the third motor 4034, and a locking device 4036 fixed to the second end of the second rotating arm 4035 and used to lock the spray gun 4037.

[0039] By starting the second motor 4032 to drive the first rotating arm 4033 to rotate, and the third motor 4034 to drive the second rotating arm 4035 to rotate, the spray gun 4037 locked by the locking device 4036 can be adjusted to deflect, thereby adjusting the direction of the nozzle of the spray gun 4037 downward / upward to meet different spraying needs; automatic adjustment, convenient and flexible.

[0040] Among them, see Figure 4 As shown, the first fastener 404 includes a right-angled stopper 4041 fixed to the inner side of one end of the main arm 401 close to the auxiliary arm 402, a first locking member for locking the auxiliary arm 402 swung to the first swing position with a right-angled side of the stopper 4041, and a second locking member for locking the auxiliary arm 402 swung to the second swing position with another right-angled side of the stopper 4041.

[0041] Specifically, the first locking member includes a first positioning bolt, a third locking hole opened on the side of the stop block 4041 facing the auxiliary arm 402 overlapping with the corresponding main arm 401, and a fifth locking hole opened on the auxiliary arm 402. When the first positioning bolt passes through the fifth locking hole and is inserted into the third locking hole, the auxiliary arm 402 is fixed to the corresponding main arm 401, and the auxiliary arm 402 overlaps with the corresponding main arm 401.

[0042] The second locking member includes a first positioning bolt, a fourth locking hole 4042 and a fifth locking hole, which are provided on the side of the stopper 4041 facing the auxiliary arm 402 which is perpendicular to the corresponding main arm 401. When the first positioning bolt passes through the fifth locking hole and is inserted into the fourth locking hole 4042, the auxiliary arm 402 is fixed to the corresponding main arm 401, and the relative inner side of the auxiliary arm 402 is perpendicular to the corresponding main arm 401.

[0043] By adjusting the position of the auxiliary arm 402 and the corresponding main arm 401, different spraying requirements can be met; by adjusting the auxiliary arm 402 to overlap with the corresponding main arm 401, the corresponding two spray gun assemblies 403 on the two auxiliary arms 402 can be respectively oriented to the two adjacent spraying surfaces of the object to be sprayed, so as to achieve double-sided spraying during spraying; by adjusting the auxiliary arm 402 to rotate 270° until the relative inner side of the auxiliary arm 402 is perpendicular to the corresponding main arm 401, the two spray gun assemblies 403 on the two auxiliary arms 402 can be respectively oriented to the other two surfaces of the object to be sprayed, and the spraying direction of the spray gun assembly 403 can be adjusted without moving the position of the mobile equipment, which is convenient to adjust and has high construction efficiency; the auxiliary arm 402 and the main arm 401 are fixed with the first fastener 404 to ensure stability during the spraying process.

[0044] Among them, see Figure 3As shown, the lifting mechanism 2 is pivotally connected to the two main arms 401 through the positioning plate 3, and the first locking member 405 includes a second fixing bolt, a connecting piece 4051 fixed on the corresponding main arm 401, a first locking hole 4052 penetrating along the thickness direction of the connecting piece 4051, and a plurality of second locking holes opened on the top of the positioning plate 3, and the second fixing bolt passes through the first locking hole 4052 and is selectively inserted into the second locking hole to fix the main arm 401 to the positioning plate 3.

[0045] In this embodiment, after the two main arms 401 are fixed by the first locking member 405, the angle between the two main arms 401 is 90°;

[0046] The two main arms 401 are adjusted to align the first locking hole 4052 on the connecting piece 4051 on the main arm 401 with the corresponding second locking hole, and then the second fixing bolt is inserted and fixed so that the relative inner sides of the two main arms 401 are vertical after being fixed, thereby ensuring stability.

[0048] S1. Before construction, adjust the relative inner sides of the two main arms 401 to be vertical, and align the first locking hole 4052 on the connecting piece 4051 with the second locking hole on the positioning top, and then pass the second fixing bolt through the first locking hole 4052 and insert it into the aligned second locking hole to fix the main arm 401 and the positioning plate 3;

[0049] S2, adjust the two auxiliary arms 402 to overlap with the corresponding two main arms 401 respectively, and align the fifth locking hole on the auxiliary arm 402 with the third locking hole on the stopper 4041, and then pass the first fixing bolt through the fifth locking hole and insert it into the third locking hole to fix the auxiliary arm 402 to the main arm 401;

[0052] S5. After spraying the two adjacent sides of the object to be sprayed, remove the first fixing bolt, adjust one side of the two auxiliary arms 402 to be perpendicular to the inner sides of the two corresponding main arms 401, and make the two spray guns 4037 on the auxiliary arms 402 correspond to the other two sides of the object to be sprayed, and align the fifth locking hole with the fourth locking hole 4042 on the stopper 4041, and then insert the first fixing bolt through the fifth locking hole into the fourth locking hole 4042 to fix the auxiliary arm 402 to the corresponding main arm 401;
