Description

Technical Field

[0001] This utility model relates to the field of cold spraying technology, and more specifically, to a cold spraying device. Background Technology

[0002] Cold spraying, also known as cold aerodynamic spraying, is a surface coating technology based on aerodynamics. Cold spraying technology uses a high-pressure gas source to accelerate solid particles to extremely high speeds, causing them to impact the substrate in a completely solid state, thereby depositing and forming a coating. The main feature of this technology is its low operating temperature, which allows the coating to be deposited without melting the material, thus maintaining the original properties of the material. Cold spraying equipment is inevitably used in the process of cold spraying.

[0003] However, most existing cold spray coating equipment typically requires the item to be sprayed to be placed on a workbench, and then the user sprays it by hand using a spray gun. This method requires the user to manually adjust the position of the item before the entire item can be sprayed, which not only increases the user's workload but also reduces the spraying efficiency of the cold spray coating equipment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cold spraying device. Through the arrangement of the processing mechanism, the item can be sprayed completely without changing its position, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold spraying device, comprising a housing, a fixed box provided on one side of the housing, a first through hole provided on the opposite side of the housing and the fixed box, a fan provided inside the fixed box, a second through hole provided on the other side of the fixed box, a positioning ring provided on the other side of the fixed box, a collection bag provided inside the positioning ring, a fixed ring provided inside the collection bag, and a processing mechanism provided on the top of the housing.

[0006] In a preferred embodiment, the processing mechanism includes a fixed plate, a motor is provided on the top of the fixed plate, and the output end of the motor passes through the fixed plate and extends to the outside of the fixed plate.

[0007] In a preferred embodiment, a lead screw is provided at one end of the motor output terminal located outside the fixed plate, and an adjustment plate is provided on the lead screw. The bottom of the adjustment plate penetrates the housing and extends into the housing.

[0008] In a preferred embodiment, the adjusting plate is provided with a connecting ring at the bottom of the housing, the connecting ring has an annular groove inside, and the inner wall of the connecting ring has a plurality of third through holes.

[0009] In a preferred embodiment, each of the several third through holes is provided with a nozzle, and the annular groove is provided with a flexible hose, one end of which passes through the connecting ring and the housing and extends to the outside of the housing.

[0010] In a preferred embodiment, a placement ring is provided at the bottom of the inner cavity of the box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By designing a processing mechanism, when spraying items, simply place the item into the placement ring inside the box. Then, start the motor to drive the lead screw, which in turn moves the adjusting plate downwards, causing the connecting ring to move downwards. As the connecting ring moves downwards, multiple nozzles can spray the item comprehensively. This spraying method not only reduces the user's workload but also improves the spraying efficiency. The addition of a fixed box, fan, and collection bag allows the fan to suck up residual spraying powder generated during spraying and collect it in the collection bag, facilitating powder reuse and eliminating the need to clean the box's internal cavity. The use of a fixed ring and positioning ring to install the collection bag makes it easy to put in and take out the bag. Through this series of reasonable designs, the practicality of the device is significantly improved. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-4 The cold spraying device shown includes a housing 1, a fixed box 2 on one side of the housing 1, and a first through hole on the opposite side of the housing 1 and the fixed box 2. A fan 3 is installed inside the fixed box 2, and a second through hole is installed on the other side of the fixed box 2. A positioning ring 4 is installed on the other side of the fixed box 2, and a collection bag 5 is installed inside the positioning ring 4. A fixing ring 6 is installed inside the collection bag 5. By adding the fixed box 2, the fan 3 and the collection bag 5, the residual powder generated during spraying is sucked into the collection bag 5 for collection. The arrangement of the collection bag 5 by using the fixing ring 6 in conjunction with the positioning ring 4 facilitates the placement and removal of the collection bag 5. The positioning ring 4 is made of rubber material. A processing mechanism is installed on the top of the housing 1.

[0020] As attached Figure 1 , 2 As shown in Figure 4, the processing mechanism includes a fixed plate 7. A motor 8 is mounted on the top of the fixed plate 7. The output end of the motor 8 passes through the fixed plate 7 and extends to the outside of the fixed plate 7. The fixed plate 7 is U-shaped. A lead screw 9 is mounted on the end of the motor 8 located outside the fixed plate 7. An adjusting plate 10 is mounted on the lead screw 9. The bottom of the adjusting plate 10 passes through the housing 1 and extends into the housing 1. The motor 8 drives the lead screw 9 to operate, allowing the adjusting plate 10 located on the lead screw 9 to move. A connecting ring 11 is mounted on the bottom of the adjusting plate 10 inside the housing 1. The connecting ring 11 has an opening inside. The device is provided with an annular groove and several third through holes on the inner wall of the connecting ring 11. The adjustment plate 10 is in contact with the connecting ring 11, so that the adjustment plate 10 can drive the connecting ring 11 to move when it moves. Each of the several third through holes is provided with a nozzle 12. A hose 13 is provided inside the annular groove. One end of the hose 13 passes through the connecting ring 11 and the housing 1 and extends to the outside of the housing 1. With the addition of the annular groove, the hose 13 and the nozzle 12, it is convenient to use the hose 13 to connect to the main unit of the spraying equipment and then use the hose 13 to guide the spraying material into the annular groove and spray it out through the nozzle 12.

[0021] As attached Figure 2 As shown, a placement ring 14 is provided at the bottom of the inner cavity of the box 1, which provides a position for placing items.

[0022] The working principle of this utility model is as follows: When using this device to spray an item, first connect the hose 13 to the external cold spraying device host. After the connection is completed, open the box door and put the item into the placement ring 14 set inside the box 1. After the placement is completed, close the box 1 and start the cold spraying device host, motor 8 and fan 3. The start of motor 8 drives the lead screw 9 to operate, and then the adjusting plate 10 drives the connecting ring 11 to move downward. At the same time as the connecting ring 11 moves downward, the material supplied by the cold spraying device host through the hose 13 is sprayed onto the item through the nozzle 12 to spray the item all over. The start of fan 3 guides the excess powder generated during spraying into the collection bag 5 for collection.
