DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a surface painting equipment for wooden door production, comprising a base 1 and a conveyor belt 2 arranged thereon, the conveyor belt 2 is provided with a painting component 3, the painting component 3 comprises a U-shaped part 306, a plurality of groups of nozzles 307 are arranged on the U-shaped part 306, a telescopic tube 304 is arranged on the top of the U-shaped part 306, the other end of the telescopic tube 304 is connected to a raw material box 302 through a pressure pump 303, and is used for pressurized spraying of paint raw materials;

[0027] The base 1 is provided with a rotating component 6, which includes a roller 605, on which a roller 8 is rotatably provided via a support plate 7, a clamping plate 10 is provided in the roller 605 by pressing an electric telescopic rod 9, and a driving wheel 11 is rotatably provided on the clamping plate 10 for flipping the wooden door.

[0028] The paint spraying component 3 includes a paint spraying bracket 301, which is connected to a raw material box 302 and a pressure pump 303. An electric telescopic rod 305 is provided on the paint spraying bracket 301, and the other end of the electric telescopic rod 305 is connected to a U-shaped piece 306. A telescopic tube 304 passes through the paint spraying bracket 301 and is connected to the pressure pump 303. The rotating component 6 includes a rotating bracket 601, on which a limiting wheel 602 is rotatably provided. A supporting bracket 603 is provided on the base 1, on which a supporting wheel 604 is rotatably provided, and the supporting wheel 604 is in contact with a roller 605.

[0029] A limiting groove is arranged on the limiting wheel 602, the thickness of the gear ring 606 is smaller than the width of the limiting groove, an anti-slip layer is arranged on the supporting wheel 604, a plurality of groups of freely rotating rollers 8 with equal intervals are arranged on the supporting plate 7, a rotating motor is arranged on the clamping plate 10, the rotating motor is connected to the driving wheel 11, a gap exists between the outer side surface of the drum 605 and the base 1, a plurality of groups of supporting wheels 604 and limiting wheels 602 are symmetrically distributed on both sides of the drum 605, a hot air blower is arranged on the clamping plate 10, and the air outlet of the hot air blower faces the direction of the roller 8.

[0030] This device can effectively improve the integrity of the painting process on all surfaces of the wooden door. Compared with the traditional device, this device adopts a vertical flipping method to ensure that each surface of the wooden door can be evenly sprayed, thereby improving the automation efficiency of the painting process.

[0031] When the device is in working condition, the wooden door is placed on the conveyor belt 2 to facilitate the transmission of the wooden door. When the wooden door moves to the bottom of the paint spraying part 3 under the drive of the conveyor belt 2, the pressure pump 303 starts to work, so that the paint raw materials in the raw material box 302 are pressurized and conveyed to the telescopic tube 304. At this time, according to the thickness of different wooden doors, the U-shaped part 306 is controlled by the electric telescopic rod 305 to adjust the height, thereby ensuring that the distance between the multiple groups of nozzles 307 and the surface of the wooden door is appropriate. At this time, the high-pressure paint enters the U-shaped part 306 through the telescopic tube 304, and the paint raw materials can be diverted to the multiple groups of nozzles 307 through the structure of the branch pipe, thereby ensuring the stability of the painting effect of the device. The telescopic tube 304 can ensure the stability of the paint raw material transmission during the lifting and lowering transmission of the electric telescopic rod 305.

[0032] After the wooden door has been painted for the first time, it enters the drum 605 under the conveyor belt 2. The roller 8 can reduce the friction between the wooden door and the support plate 7. When the wooden door completely enters the drum 605, the hot air blower arranged on the clamping plate 10 is started (the hot air blower is not shown in the drawings because it is a common prior art). The hot air blower on the clamping plate 10 can accelerate the drying and shaping of the paint on the surface of the wooden door, thereby ensuring that the paint surface of the wooden door can be effectively shaped before the wooden door is clamped and fixed, and avoiding the adhesion of undried paint on the surface of the driving wheel 11.

[0033] When the painted surface of the wooden door has dried and set, the electric telescopic rod 9 is pressed to drive the clamping plate 10 to move downward, so that the driving wheel 11 on the clamping plate 10 and the roller 8 on the supporting plate 7 are combined to squeeze and clamp the side of the wooden door, thereby preventing the wooden door from shaking inside the device. At this time, the driving motor 4 is started, and the gear ring 606 is driven to rotate through the transmission gear 5, thereby realizing the vertical rotation effect of the roller 605. Through the rotation of the roller 605, the wooden door is driven to flip in the vertical direction. When the roller 605 rotates After 180 degrees, the wooden door is completely flipped over. At this time, the wooden door is pressed on the driving wheel 11 on the clamping plate 10, and the driving wheel 11 can be used to drive the wooden door in the direction of the conveyor belt 2, so that the wooden door returns to the conveyor belt 2. When the wooden door slides in the direction of the conveyor belt 2, the paint spraying component 3 starts working again. At this time, the paint spraying component 3 can evenly paint the other side of the wooden door. After the painting is completed, the wooden door is driven out from the conveyor belt 2 away from the roller 605, thereby realizing the discharging effect of the device and realizing the complete processing process of the device.

[0034] Embodiment 2: Figure 1-5As shown, a surface painting equipment for wooden door production disclosed in Example 2 of the utility model has a structure basically the same as that in Example 1, except that a motor bracket is provided on the base 1, a driving motor 4 is provided on the motor bracket, a transmission gear 5 is provided on the driving motor 4, a gear ring 606 is provided on the roller 605, the gear ring 606 is meshedly connected with the transmission gear 5, a plurality of groups of equally spaced nozzles 307 are provided on the U-shaped part 306, a branch pipe is provided inside the U-shaped part 306, one end of the converging pipe is connected to the telescopic pipe 304, and the other end of the branch pipe is connected to the plurality of groups of nozzles 307.

[0035] The structure of the U-shaped piece 306 can achieve the effect of multi-angle painting of the device, so that during the painting process, the side of the wooden door can be painted at the same time as the front is being painted, thereby avoiding problems such as missing the side surface of the wooden door.
