Description

Technical Field

[0001] This utility model belongs to the field of powder coating technology, and is particularly related to a bottom structure of a powder spray booth. Background Technology

[0002] Current automated powder coating is achieved within a spray booth, with a powder recovery structure at the bottom of each booth. For example, utility model patent CN221514963U discloses a powder spray booth base and device. The base body has a downward-facing recovery cavity in the middle, within which two symmetrically arranged, flip-up powder collection plate units are positioned. After flipping open, these units can collect powder escaping from the spray booth through a negative pressure mechanism. While this powder spray booth base achieves good powder recovery, it requires a cleaning device on each side of the spray booth bottom to blow the accumulated powder towards the powder collection plate units. Furthermore, the two powder collection plate units are controlled by two rotating drive components. Having two sets of cleaning devices and rotating drive components increases equipment costs. Simultaneous cleaning by the cleaning devices and control of the powder collection plate units by the two drive components can easily lead to synchronization issues. Therefore, improvements are necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a bottom structure for a powder spraying booth. By simply installing a first air knife, the powder accumulated on the baffle can be blown toward the two flaps, resulting in strong synchronization in powder cleaning and reducing equipment costs.

[0004] A powder spray booth bottom structure, comprising:

[0005] The base has a recycling trough at the top and a horizontal baffle at the top of the recycling trough along the length of the base. The baffle is spaced at a predetermined distance from the sides of the base. The base has a discharge port on its side for discharging powder.

[0006] A pair of flaps are located on both sides of the baffle. The flaps are rotatably connected to both ends inside the base via a rotating shaft, which is connected to a rotating mechanism.

[0007] The first air knife is located at the top of the baffle along the length of the baffle. Air outlet slits are provided on both sides of the first air knife to blow the powder accumulated on the baffle toward the two flaps respectively.

[0008] Furthermore, a second air knife is provided on one side of the flip plate along the length direction for blowing away powder accumulated at the bottom of the base.

[0009] Furthermore, a first air intake channel is provided at one end of the rotating shaft, an air inlet is provided on the side of the second air knife near the flap, and a second air intake channel is provided inside the flap. One end of the second air intake channel is connected to the air inlet, and the other end of the air intake channel is connected to the first air intake channel.

[0010] Furthermore, the discharge port is located in the middle of one end of the base.

[0011] Furthermore, the rotating mechanism includes a drive motor and a transmission belt. The output shaft of the drive motor is connected to one end of one of the rotating shafts, and a first gear ring is coaxially provided on the output shaft of the drive motor. A second gear ring is coaxially provided on one end of the other rotating shaft. The second gear ring is meshed with a third gear ring. The third gear ring is coaxially provided on a connecting shaft. The connecting shaft is rotatably connected to one end of the base. A fourth gear ring is coaxially provided on the connecting shaft. The fourth gear ring and the first gear ring are meshed within the transmission belt.

[0012] To achieve the above objectives, the present invention employs the following technology:

[0013] A powder spray booth bottom structure, comprising:

[0014] The base has a recycling trough at the top and a horizontal baffle at the top of the recycling trough along the length of the base. The baffle is spaced at a predetermined distance from the sides of the base. The base has a discharge port on its side for discharging powder.

[0015] A pair of flaps are located on both sides of the baffle. The flaps are rotatably connected to both ends inside the base via a rotating shaft, which is connected to a rotating mechanism.

[0016] The first air knife is located at the top of the baffle along the length of the baffle. Air outlet slits are provided on both sides of the first air knife to blow the powder accumulated on the baffle toward the two flaps respectively.

[0017] Furthermore, a second air knife is provided on one side of the flip plate along the length direction for blowing away powder accumulated at the bottom of the base.

[0018] Furthermore, a first air intake channel is provided at one end of the rotating shaft, an air inlet is provided on the side of the second air knife near the flap, and a second air intake channel is provided inside the flap. One end of the second air intake channel is connected to the air inlet, and the other end of the air intake channel is connected to the first air intake channel.

[0019] Furthermore, the discharge port is located in the middle of one end of the base.

[0020] Furthermore, the rotating mechanism includes a drive motor and a transmission belt. The output shaft of the drive motor is connected to one end of one of the rotating shafts, and a first gear ring is coaxially provided on the output shaft of the drive motor. A second gear ring is coaxially provided on one end of the other rotating shaft. The second gear ring is meshed with a third gear ring. The third gear ring is coaxially provided on a connecting shaft. The connecting shaft is rotatably connected to one end of the base. A fourth gear ring is coaxially provided on the connecting shaft. The fourth gear ring and the first gear ring are meshed within the transmission belt.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. A single air knife can blow the powder accumulated on the baffle towards the two flaps, reducing equipment costs and ensuring high synchronization in blowing powder to both sides. A single power source, the drive motor, can drive the two flaps to rotate synchronously. Compared to using two rotating drive components as power sources, this reduces equipment failure rate and improves synchronization.

[0023] 2. While the second air knife blows air, it rotates under the action of the flap, which can blow up the powder accumulated at the bottom of the base, making it easier to be adsorbed and collected by the negative pressure mechanism, thus avoiding a large amount of powder accumulation at the bottom of the base.

Detailed Implementation

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0032] This application provides a powder spraying booth bottom structure, such as... Figures 1-6 As shown, it includes a base 1, a flip plate 2, a first air knife 4, etc.

[0033] Specifically, a recycling trough 101 is provided on the top of the base 1, and a transverse baffle 102 is provided on the top of the recycling trough 101 along the length of the base 1. The baffle 102 is at a preset distance from the two sides of the base 1. A discharge port 103 is provided on the side of the base 1 for discharging powder. A pair of flip plates 2 are provided on both sides of the baffle 102. The flip plates 2 are rotatably connected to both ends inside the base 1 through a rotating shaft 3. The rotating shaft 3 is connected to a rotating mechanism. A first air knife 4 is provided on the top of the baffle 102 along the length of the baffle 102. Air outlet slits are provided on both sides of the first air knife 4. Specifically, the two air outlet slits are connected to the air inlet chamber of the first air knife 4 for blowing the powder accumulated on the baffle 102 toward the two flip plates 2 respectively.

[0034] In actual use, when performing powder spraying operations in the powder spraying booth, the control mechanism drives the rotating shaft 3 and the flap 2 to rotate to the open state. Air is then drawn from the discharge port 103 by the negative pressure mechanism, allowing the powder not adhering to the workpiece to be absorbed and collected within the spraying booth. After prolonged spraying operations, the first air knife 4 is activated, causing high-pressure air to be simultaneously ejected from both air outlets. This divides the powder accumulated on the baffle 102 into two parts, blowing them towards the two flaps 2 respectively, keeping the powder in a suspended state so that it can be adsorbed and collected by the negative pressure mechanism.

[0035] For details, please refer to Figures 1-3 , Figure 5The rotating mechanism includes a drive motor 6 and a transmission belt 601. The output shaft of the drive motor 6 is connected to one end of one of the rotating shafts 3, and a first gear ring 602 is coaxially provided on the output shaft of the drive motor 6. A second gear ring 603 is coaxially provided on one end of the other rotating shaft 3. The second gear ring 603 is meshed with a third gear ring 604. The third gear ring 604 is coaxially provided on a connecting shaft 606. The connecting shaft 606 is rotatably connected to one end of the base 1. A fourth gear ring 605 is coaxially provided on the connecting shaft 606. The fourth gear ring 605 and the first gear ring 602 are meshed in the transmission belt 601. After the drive motor 6 drives one of the rotating shafts 3 and the first gear ring 602 to rotate, the first gear ring 602 will drive the transmission belt 601 to rotate, the transmission belt 601 will drive the fourth gear ring 605 and the connecting shaft 606 to rotate, and the connecting shaft 606 will drive the second gear ring 603 and the other rotating shaft 3 to rotate synchronously through the third gear ring 604. Because the third gear ring 604 rotates in the same direction as the first gear ring 602, and the second gear ring 603 rotates in the opposite direction to the first gear ring 602, the two rotating shafts 3 can rotate synchronously in opposite directions, thereby causing the two flaps 2 to rotate synchronously in opposite directions.

[0036] Preferred options, please refer to Figure 4 , Figure 5 Each side of the flap 2 is equipped with a second air knife 5 along its length. The second air knife 5 blows air while controlling the rotation of the flap 2, which can blow up the powder accumulated at the bottom of the base 1, facilitating its collection by the negative pressure mechanism and preventing excessive powder accumulation at the bottom of the base 1. For details, please refer to... Figure 6 The discharge port 103 is located in the middle of one end of the base 1. Because the two second air knives 5 can blow the powder accumulated at the bottom of the base 1 from both sides towards the middle, the discharge port 103, located in the middle of one end of the base 1, has a better adsorption effect on the powder. For more details, please refer to... Figure 5 One end of the rotating shaft 3 is provided with a first air intake channel 301, and the second air knife 5 is provided with an air intake port 501 on the side near the flap 2. The flap 2 is provided with a second air intake channel 201. One end of the second air intake channel 201 is connected to the air intake port 501, and the other end of the air intake channel is connected to the first air intake channel 301. When in use, the compressed air delivery pipe can be rotatably connected to the first air intake channel 301, which can prevent the compressed air delivery pipe from getting tangled during the rotation of the flap 2.

[0037] The above are only some of the embodiments listed in this application and are not intended to limit this application.
