It is mainly used to melt metal powder and then shape, manufacture and process it. Its working principle is to melt and shape the metal powder through a powder supply system and a laser system. The control system and integrated software are responsible for controlling and monitoring the entire process to ensure improved quality and precision.

[0003] Patent CN219942826U discloses a bonding machine, relating to the field of powder coating technology. The machine includes a staircase with a cooling mechanism at its back, a feeding mechanism at its top, a bonding mechanism on its right side, and an electrical control box at its front. The feeding mechanism comprises two material bins, each containing a storage hopper. Each storage hopper has an electrically controlled valve at its bottom, a volume control hopper below each valve, and a weighing device at the bottom of each volume control hopper. Each weighing device has an electric push rod on its left side and a discharge pipe at its bottom. The bonding mechanism includes a power box with a bonding vessel at its top. This invention, through its design, effectively ensures a precise ratio between powder coating and metal powder, preventing mixing between different batches and guaranteeing product quality. However, in implementing this technical solution, at least the following problems were found in the existing technology:

[0004] When using a bonding machine, multiple sets of raw materials are usually directly fed into the bonding vessel of the bonding machine and mixed and stirred in a concentrated manner. It is not possible to use a premixing method to mix the multiple raw materials entering the bonding vessel in advance, which results in poor mixing effect of multiple raw materials in the subsequent bonding vessel and easy to create mixing dead zones. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a bonding machine for metal powder coatings, which solves the problem that it is impossible to use a premixing method to premix the various raw materials entering the bonding kettle.

[0006] This utility model is implemented as follows: a bonding machine for metal powder coating includes a bonding machine body and an auxiliary tank located on the top of the bonding kettle on the bonding machine body. The bottom end of the auxiliary tank is connected to a vertical pipe, and the bottom end of the vertical pipe is connected to the bonding kettle of the bonding machine body. Multiple sets of feeding pipes are evenly connected to the auxiliary tank, and the top end of each set of feeding pipes is connected to a placement cylinder. An auxiliary premixing component is provided inside the auxiliary tank.

[0007] In a preferred embodiment of this invention, the auxiliary premixing component includes a vertical shaft rotatably mounted on the top of the inner cavity of the auxiliary tank. A stirring blade located at the bottom of the vertical shaft is fixed to the bottom of the feed pipe. A motor is fixed to the feed pipe via a connecting frame, and the motor's output shaft is fixed to the top of the vertical shaft. Guide plates located below the stirring blades are fixed to both sides of the inner cavity of the auxiliary tank. A guide seat is fixed to one side of the guide plates that are close to each other. A positioning shaft is rotatably mounted on one side of the bottom of the inner cavity of the auxiliary tank. Multiple sets of impact plates that cooperate with the guide seats are evenly fixed on the positioning shaft. A backlash plate that cooperates with the impact plates is fixed to the bottom of the other side of the inner cavity of the auxiliary tank. A first connecting shaft and a second connecting shaft are rotatably mounted on the front of the auxiliary tank along the left-right direction via bearing seats. Pulleys are fixed to both ends of the first connecting shaft, the top of the vertical shaft, and the top of the second connecting shaft. The surfaces of adjacent sets of pulleys are connected by belt drive. Bevel gears capable of meshing are fixed to the ends of the first connecting shaft and the positioning shaft that are close to each other.

[0008] As a preferred embodiment of this invention, the front and back sides of the inner cavity of the flow guide seat are both inclined, and the longitudinal width of the impact plate is greater than the longitudinal width of the bottom of the inner wall of the flow guide seat.

[0009] As a preferred embodiment of this invention, the number of impact plates on the positioning shaft is at least five sets.

[0010] As a preferred embodiment of this utility model, the backflush plate has an overall downward inclined structure, and the bottom of the auxiliary tank has a frustum-shaped structure.

[0011] As a preferred embodiment of this invention, an auxiliary solenoid valve is provided on the vertical pipe.

[0012] As a preferred embodiment of this utility model, the left side of the auxiliary tank is symmetrically fixed with an extension bracket along the front-back direction, and the bottom end of each set of extension brackets is fixed to the outer shell of the bonding machine body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, by setting up an auxiliary premixing component, utilizes a motor as the driving source. With the cooperation of pulleys and gears, it can drive the stirring blades and multiple sets of impact plates to rotate synchronously and rapidly, so as to quickly and synchronously disperse various preparation materials falling through the feed pipe, thereby facilitating the initial premixing of various materials. The multiple sets of materials dispersed and thrown by the stirring blades will contact and collide with the inner wall of the auxiliary tank, thereby further premixing the materials. At the same time, the design of the guide plate and guide seat can control the falling direction and position of the thrown materials. The use of multiple sets of synchronously rotating impact plates can disperse and throw the materials falling through the guide seat in batches evenly. With the blocking and limiting of the backflushing plate, multiple materials can be premixed again. At this time, the multi-directional and multi-form premixing method can mix multiple materials entering the bonding vessel in advance, improve the mixing effect of subsequent materials in the bonding vessel, and effectively avoid the formation of mixing dead zones.

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 3As shown in the figure, the present invention provides a bonding machine for metal powder coating, including a bonding machine body 1, and an auxiliary tank 2 located on the top of the bonding kettle on the bonding machine body 1. A controller is provided on the bonding machine body 1. The bottom end of the auxiliary tank 2 is connected to a vertical pipe 3 and the bottom end of the vertical pipe 3 is connected to the bonding kettle of the bonding machine body 1. Multiple sets of feeding pipes 6 are evenly connected to the auxiliary tank 2. The top end of each set of feeding pipes 6 is connected to a placement cylinder 5. An auxiliary premixing component is provided inside the auxiliary tank 2. By setting the auxiliary premixing component, a multi-directional and multi-form premixing method can be adopted to premix multiple raw materials entering the bonding kettle, thereby improving the mixing effect of subsequent raw materials in the bonding kettle and effectively avoiding mixing dead zones.

[0023] As a preferred embodiment of this utility model, the auxiliary premixing component includes a vertical shaft 7 rotatably mounted on the top of the inner cavity of the auxiliary tank 2. A stirring blade 9 located at the bottom of the feed pipe 6 is fixed to the bottom of the vertical shaft 7. A motor 8 is fixed to the feed pipe 6 via a connecting frame, and the output shaft of the motor 8 is fixed to the top of the vertical shaft 7. Guide plates 10 located below the stirring blade 9 are fixed to both sides of the inner cavity of the auxiliary tank 2. A guide seat 11 is fixed to the side of the guide plates 10 that are close to each other. The front and back of the guide seat 11 are fixed to the inner wall of the auxiliary tank 2. A positioning shaft 12 is rotatably mounted on one side of the bottom of the inner cavity of the auxiliary tank 2. Multiple sets of impact plates 13 that cooperate with the guide seat 11 are evenly fixed on the positioning shaft 12. A backwash plate 14 that cooperates with the impact plate 13 is fixed to the bottom of the other side of the inner cavity of the auxiliary tank 2. A first connecting shaft 18 is rotatably mounted on the front of the auxiliary tank 2 along the left-right direction via bearing seats. The first connecting shaft 18 and the second connecting shaft 15 are both fixed with pulleys 16 at both ends, the top of the vertical shaft 7 and the top of the second connecting shaft 15. The surfaces of two adjacent sets of pulleys 16 are connected by belt drive. The first connecting shaft 18 and the positioning shaft 12 are fixed with bevel gears 17 that can mesh with each other at their close ends. The design of the motor 8 can provide a driving source for the rotation of the stirring blades 9 and multiple sets of impact plates 13, so as to initially disperse and premix the various raw materials falling through the feed pipe 6. The dispersed and thrown raw materials will contact and collide with the inner wall of the auxiliary tank 2 to premix the raw materials again. Under the guidance of the guide plate 10 and the guide seat 11, the raw materials falling through the guide seat 11 can be dispersed and thrown in batches evenly using multiple sets of rotatable impact plates 13. With the blocking and limiting of the backflushing plate 14, the various raw materials can be premixed again.

[0024] As a preferred embodiment of this utility model, the front and back sides of the inner cavity of the flow guide seat 11 are both inclined, and the longitudinal width of the impact plate 13 is greater than the longitudinal width of the bottom of the inner wall of the flow guide seat 11. The inclined structure design, combined with the width difference, can effectively guide the raw materials, so that the impact plate 13 can completely disperse the various raw materials falling through the flow guide seat 11 and avoid the formation of dead corners in the dispersion.

[0025] As a preferred embodiment of this invention, the number of impact plates 13 on the positioning shaft 12 is at least five sets, which can increase the frequency of the impact plates 13 in dispersing the raw materials, thereby improving the dispersing and mixing effect and enabling multiple raw materials to be mixed more thoroughly.

[0026] As a preferred embodiment of this utility model, the backflush plate 14 has a downward inclined structure, which can avoid obstructing the normal falling of the raw material while backflushing. The inclined design allows some of the raw material to be thrown upward again and come into contact with the impact plate 13 again, so as to further improve the premixing effect. The bottom of the auxiliary tank 2 has a frustum-shaped structure, which facilitates material feeding and avoids the accumulation of raw material inside the auxiliary tank 2.

[0027] As a preferred embodiment of this utility model, an auxiliary solenoid valve is provided on the vertical pipe 3, which can control the opening and closing state of the vertical pipe 3, facilitating material feeding and overall sealing of the vertical pipe 3.

[0028] As a preferred embodiment of this utility model, an extension bracket 4 is symmetrically fixed on the left side of the auxiliary tank 2 along the front-back direction. The bottom end of each set of extension brackets 4 is fixed on the outer shell of the bonding machine body 1. The design of the extension bracket 4 can reinforce the auxiliary tank 2 and improve its overall stability.

[0029] The working principle of this utility model:

[0030] refer to Figures 1 to 3 The user feeds multiple raw materials for preparing metal powder coatings into the auxiliary tank 2 via multiple sets of placement cylinders 5. The user then activates the motor 8 via a controller. The motor 8 drives the vertical shaft 7 to rotate, which in turn drives the stirring blades 9 to rotate. This rapidly and synchronously disperses the various raw materials falling through the feed pipe 6, performing initial pre-mixing. The materials dispersed and propelled by the stirring blades 9 then contact and collide with the inner wall of the auxiliary tank 2, using the collision force to further disperse and mix the materials. Subsequently, the materials pass through the guide plate 1... The material enters the guide seat 11. At this time, the guide seat 11 can control the falling direction and position of the material after it is thrown. When the motor 8 drives the vertical shaft 7 to rotate, the rotation of multiple sets of pulleys 16 and the meshing of bevel gears 17 can drive multiple sets of impact plates 13 to rotate. This can evenly disperse and throw the material falling through the guide seat 11 in batches. With the blocking and limiting of the back impact plate 14, multiple materials can be premixed again. After multiple premixing, multiple materials can fall through the vertical pipe 3 into the bonding tank of the bonding machine body 1.
