[0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. There are two types of spray guns: general pressure type and pressurized type. There are also pressure spray guns, Carle spray guns, and automatic recovery spray guns. Spray guns are used in the industry to directly load paint, that is, simple spray guns, which can be installed in automated equipment, such as automatic glue sprayers, automatic glue coating machines, automatic paint sprayers, coating machines and other spraying equipment.

[0003] The prior art has a publication number of CN219273361U, and the patent name is a spray gun with an adjustable spray range. The patent can control whether the spray material is sprayed out by cooperating with the spray seat in the nozzle adjustment part, and then realize the adjustment of the spray discharge, and obtain an adjustable spray range; the spray seat can be adjusted by the rotating part, so that it can rotate or adjust the spray angle, which can facilitate the angle adjustment in the actual spraying process and the spraying operation. However, when controlling the spray range of the spray gun, the blocked material distribution trough easily causes the sprayed raw materials to liquefy and accumulate inside, resulting in the need to spray out and discard the liquefied spray raw materials inside when the nozzle is unblocked, resulting in waste, and blocking the nozzle on one side will cause the nozzle on the other side to respond to pressure and increase the spraying force. The nozzle without a fixing device is affected by the reaction force during the spraying, resulting in a rotation deviation to one side on the rotating part, affecting the spraying effect.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-4 A spray gun for a spray coating line is provided, comprising a gun body 1, a gun head 2 is arranged on the gun body 1, a nozzle 3 is arranged on the gun head 2, an injection groove 4 is arranged inside the gun body 1, an adjusting component 5 for adjusting the spraying amount is arranged on the gun body 1, a diverter groove 6 connected with the injection groove 4 is opened inside the nozzle head 3, a blocking component 7 located at the entrance of the diverter groove 6 for controlling the number of discharge ports is arranged on the nozzle head 3, and a positioning component 8 for controlling the rotation angle of the nozzle is arranged on the gun head 2.

[0024] Reference Figure 2-3 , wherein the injection slot 4 is divided into five circular arrays, five parallel spray slots 10 are provided inside the nozzle 3, the top of the gun head 2 is connected to the nozzle 3 through the rotating part 9, and the nozzle 3 is connected to the gun head 2 through the rotating part 9;

[0025] Through the above-mentioned structural arrangement, the evenly distributed spraying slots 10 allow the paint to be sprayed evenly, and the rotating part 9 enables the spray head 3 to flexibly adjust its direction on the gun head 2 to increase the spraying range.

[0026] Reference Figure 1-2The adjusting assembly 5 includes an adjusting baffle 51, which is rotatably installed inside the gun body 1 and used to block the feeding amount of the injection slot 4. The gun body 1 is symmetrically provided with an adjusting slot 52, and an adjusting sleeve 53 is rotatably installed on the outer side of the gun body 1. The outer side of the adjusting baffle 51 passes through the adjusting slot 52 and is connected to the adjusting sleeve 53. The adjusting baffle 51 is provided with a through hole opposite to the injection slot 4.

[0027] With the above-mentioned structural setting, by rotating the adjusting sleeve 53, the adjusting sleeve 53 drives the adjusting baffle 51 connected thereto to rotate in the adjusting groove 52, so that the adjusting baffle 51 controls the size of the injection groove 4 as it rotates, thereby controlling the flow rate of the paint input from the injection groove 4.

[0028] Reference Figure 3-4 , wherein the blocking assembly 7 includes a blocking plate 71, and the inside of the nozzle 3 is symmetrically installed with a blocking plate 71 located at the entrance of the spray tank 10 and adapted thereto, and the top of the blocking plate 71 is connected to a knob 72 having one end penetrating and extending to the outside of the nozzle 3;

[0029] Through the above-mentioned structural arrangement, the sealing plate 71 is driven to rotate by rotating the knob 72, and the entrance of the spray slot 10 is blocked as needed to reduce the spraying amount and spraying area of ​​the paint. The sealing plate 71 is driven to rotate by rotating the knob 72 in the reverse direction, thereby releasing the blockage of the spray slot 10 and increasing the spraying amount and spraying area.

[0030] Reference Figure 3-4 , wherein the positioning assembly 8 includes a rotating seat 81, the surface of the gun head 2 is fixedly mounted with the rotating seat 81 located outside the rotating portion 9, a connecting bracket 82 is rotatably mounted on the rotating seat 81, and one end of the connecting bracket 82 is connected to the surface of the nozzle 3;

[0031] Through the above-mentioned structural setting, the rotating seat 81 and the connecting bracket 82 are both damping settings. As the nozzle 3 rotates on the gun head 2, the connecting bracket 82 changes its distance along with the direction of the nozzle 3. The damping setting enables the connecting bracket 82 to prevent the nozzle 3 that has been adjusted from shaking.

[0032] Working principle:

[0033] The first step to implement the innovation point:

[0034] Step 1: After the gun body 1 is connected to the external paint delivery pipeline, the adjusting sleeve 53 is rotated according to the spraying needs, so that the adjusting sleeve 53 drives the adjusting baffle 51 connected thereto to rotate in the adjusting groove 52. As the through hole on the adjusting baffle 51 rotates, it gradually intersects with the injection groove 4 to change the size of the connection port between the injection groove 4 and the gun head 4, thereby controlling the amount of paint input from the injection groove 4;

[0035] Step 2: Turn the knob 72 at the same time to drive the blocking plate 71 to rotate. According to needs, the blocking plate 74 blocks the entrance of the spray slot 10, and reduces the spraying amount and spraying area of ​​the paint by reducing the spraying port. At the same time, according to needs, the knob 72 can be turned in the opposite direction to drive the blocking plate 71 to rotate, and the blocking plate 10 on the spray slot 10 is released, thereby increasing the spraying amount and spraying area.
