[0012] The utility model provides a spraying device for producing plastic shells, which has the following advantages:

[0013] The invention discloses a spraying device for producing a plastic shell. First, the plastic shell is placed at the input end of a conveyor. As the conveyor operates, the plastic shell is smoothly conveyed to a designated position below a support frame. At this time, the plastic shell is located between two clamps.

In this way, the plastic shell can be turned over to different angles to achieve spraying on different sides. During the turning of the plastic shell, the two spray plates start working and cooperate with the conveyor to achieve the front and back spraying operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a spraying device for producing a plastic shell of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, the utility model is a spraying device for producing plastic shells, including a conveyor 1 for transmitting plastic shells, a support frame 3 is fixedly installed on the upper part of one side of the input end of the conveyor 1, and spray plates 4 for receiving paint are fixedly installed on both sides of the upper part of the support frame 3, and flip assemblies 5 are fixedly installed inside the two sides of the support frame 3. The flip assembly 5 includes a first electric push rod 501, a second electric push rod 503 is fixedly installed on the output end of the first electric push rod 501, and a splint 504 is rotatably installed on the output end of the second electric push rod 503. A motor 2 is also fixedly installed on one side of the conveyor 1, and the motor 2 is transmission-connected to the splint 504 through a transmission assembly 6.

[0027] In the above-mentioned spraying device for producing plastic shells, the plastic shell is first placed at the input end of the conveyor 1. As the conveyor 1 operates, the plastic shell is smoothly transported to the designated position below the support frame 3. At this time, the plastic shell is located between the two clamping plates 504. When the plastic shell reaches the designated position, the two second electric push rods 503 start working until the two clamping plates 504 firmly clamp the plastic shell. In this way, the plastic shell is stably fixed between the two clamping plates 504, ready for the subsequent flipping and spraying actions. Then, the first electric push rod 501 starts working. Since the output end of the first electric push rod 501 is connected to the second electric push rod 503, when the first electric push rod 501 performs a lifting action, it will drive the entire mechanism composed of the second electric push rod 503 and the clamping plate 504 to move upward. In this way, the plastic shell is lifted to a height suitable for spraying. While the plastic shell is being lifted, the motor 2 also starts working. The motor 2 is connected to the clamping plate 504 through the transmission assembly 6, so when the motor 2 rotates, it will drive the clamping plate 504 (and the plastic shell clamped by the clamping plate 504) to rotate together. Since the clamping plate 504 is rotatably mounted on the output end of the second electric push rod 503, a 360-degree flipping action can be achieved. In this way, the plastic shell can be flipped to different angles, so as to achieve spraying on its different sides. In the process of the plastic shell being flipped, the two spray plates 4 start working and cooperate with the conveyor 1 to achieve the front and back spraying operation. Realizing automated and efficient spraying operations can not only reduce manual operations and improve production efficiency, but also ensure uniform spraying of the paint and improve product quality.

[0028] In this embodiment, the output end of the first electric push rod 501 is fixedly connected to the lifting plate 502, and the second electric push rod 503 is fixed on the upper part of the lifting plate 502. The output end of the motor 2 is fixedly connected to the first rotating wheel 604, and one end of the driving shaft of the conveyor 1 is fixedly connected to the one-way bearing 608, and the outer ring of the one-way bearing 608 is fixedly connected to the driving shaft of the conveyor 1. The inner ring of the one-way bearing 608 is fixedly connected to the double concave rotating wheel 607, and the double concave rotating wheel 607 is transmission-connected to the first rotating wheel 604 through the first transmission belt 606.

[0029] When the motor 2 rotates forward, its output end drives the first rotating wheel 604 to rotate. Since the first rotating wheel 604 is connected to the double concave rotating wheel 607 through the first transmission belt 606, the double concave rotating wheel 607 will also rotate. Since the double concave rotating wheel 607 is connected to the drive shaft of the conveyor 1 through the one-way bearing 608, and the outer ring of the one-way bearing 608 is fixedly connected to the drive shaft of the conveyor 1, when the double concave rotating wheel 607 rotates, the inner ring of the one-way bearing 608 will also rotate, thereby driving the drive shaft of the conveyor 1 to rotate, thereby driving the conveyor 1 to work and smoothly transporting the plastic shell to the designated position below the support frame 3. When the plastic shell needs to be turned over and sprayed, the motor 2 starts to reverse. Due to the characteristics of the one-way bearing 608, when the motor 2 reverses, the inner ring of the one-way bearing 608 no longer rotates, so the rotation of the double concave rotating wheel 607 and the first rotating wheel 604 will not affect the drive shaft of the conveyor 1, and the conveyor 1 will not be driven to stop working. At this time, the first electric push rod 501 and the second electric push rod 503 continue to work, controlling the movement of the clamping plate 504 and the lifting plate 502, coordinating the turning and spraying of the plastic shell.

[0030] In this embodiment, a second rotating wheel 605 is also rotatably mounted on one side of the support frame 3, and the second rotating wheel 605 is connected to the double concave rotating wheel 607 through a second transmission belt 609, and the first transmission belt 606 and the second transmission belt 609 are arranged alternately. The second rotating wheel 605 is fixedly connected to the outer side of the second rotating wheel 603, and the driving shaft of the second electric push rod 503 is hollowly arranged. A rotating rod 602 is rotatably mounted inside the driving shaft of the second electric push rod 503, one end of the rotating rod 602 is fixedly connected to the clamping plate 504, and the other end of the rotating rod 602 is fixedly connected to the first gear 601, the thickness of the second gear 603 is greater than that of the first gear 601, and the first gear 601 is controlled by the second electric push rod 503 to movably mesh with the second gear 603.

[0031] In the standby state, the first gear 601 and the second gear 603 are not meshed, so the rotation of the motor 2 is not transmitted to the first gear 601 through the second gear 603, thereby driving the clamping plate 504 to move. When spraying is required, the second electric push rod 503 starts to work to control the drive shaft to perform a clamping action, so that the rotating rod 602 inside the drive shaft and the first gear 601 are close to the second gear 603. Since the thickness of the second gear 603 is greater than that of the first gear 601, when the first gear 601 is close to the second gear 603, the two will be meshed and connected. At this time, the working state of the motor 2 can affect the action of the clamping plate 504.

[0032] When the motor 2 rotates forward, it drives the first rotating wheel 604 to rotate, and then drives the double concave rotating wheel 607 to rotate through the first transmission belt 606. Since the double concave rotating wheel 607 is connected to the driving shaft of the conveyor 1 through the one-way bearing 608, this will drive the conveyor 1 to work and transport the plastic shell to the specified position. At the same time, since the first gear 601 is meshed with the second gear 603, the rotation of the motor 2 will also be transmitted to the first gear 601 through the second gear 603, thereby driving the rotating rod 602 and the clamping plate 504 to rotate, but at this time, no flipping action is performed, just maintaining the clamping state.

[0033] When the motor 2 is reversed, the characteristics of the one-way bearing 608 cause the conveyor 1 to stop working, while the rotation of the motor 2 can still be transmitted to the first gear 601 through the second gear 603. At this time, since the clamping plate 504 has clamped the plastic shell, the first electric push rod 501 will also lift the clamping plate 504 and the plastic shell to a height suitable for spraying. Then, the driving force of the reverse rotation of the motor 2 is transmitted to the rotating rod 602 through the first gear 601 and the second gear 603, thereby driving the clamping plate 504 to flip, thereby achieving spraying on different surfaces of the plastic shell.

[0034] The operation of the motor 2 will not affect the movement of the clamping plate 504; during the spraying operation, the operation of the motor 2 can not only drive the conveyor 1 to work, but also drive the clamping plate 504 to flip through the gear transmission when necessary. Such a design not only improves production efficiency, but also ensures the accuracy and stability of the spraying operation.

[0035] Working principle of the spraying device for plastic shell production:

[0036] First, the plastic shell is placed at the input end of the conveyor 1. As the conveyor 1 operates, the plastic shell is smoothly transported to the designated position below the support frame 3. At this time, the plastic shell is located between the two clamps 504. When the plastic shell reaches the designated position, the two second electric push rods 503 start working until the two clamps 504 firmly clamp the plastic shell. In this way, the plastic shell is stably fixed between the two clamps 504, ready for the subsequent flipping and spraying actions. Then, the first electric push rod 501 starts working. Since the output end of the first electric push rod 501 is connected to the second electric push rod 503, when the first electric push rod 501 performs a lifting action, it will drive the entire mechanism composed of the second electric push rod 503 and the clamp 504 to move upward. In this way, the plastic shell is lifted to a height suitable for spraying. While the plastic shell is being lifted, the motor 2 also starts working. The motor 2 is connected to the clamping plate 504 through the transmission assembly 6, so when the motor 2 rotates, it drives the clamping plate 504 (and the plastic shell clamped by the clamping plate 504) to rotate together. Since the clamping plate 504 is rotatably mounted on the output end of the second electric push rod 503, a 360-degree flipping action can be achieved. In this way, the plastic shell can be flipped to different angles, thereby achieving spraying on different sides of it. During the process of the plastic shell being flipped, the two spray plates 4 start working and cooperate with the conveyor 1 to achieve the front and back spraying operation.
