Description

Technical Field

[0001] This utility model relates to the field of shoe material processing equipment technology, specifically to an automated spraying device for rubber shoe materials. Background Technology

[0002] Shoes are garments used to protect the feet and facilitate walking. Shoe materials are the raw materials used in shoe manufacturing. Rubber shoe materials have excellent shock absorption properties and are commonly used as soles in athletic shoes. With the improvement of living standards, people's emphasis on leisure life, and the popularization of sports, the production of rubber shoe materials has increased significantly. With technological advancements, the production process of rubber shoe materials now involves automatic coating processes. Water-resistant and oil-resistant coatings are applied to the surface of the rubber shoe materials, giving them waterproof and oil-resistant properties, improving both performance and aesthetics.

[0003] In the existing technology, the following problems exist in the process of spraying rubber shoe materials: First, after one side of the rubber shoe material is sprayed, the staff usually needs to manually flip it over to spray the other side; Second, there will be uneven spraying, which requires re-spraying or manual touch-up by the staff, which not only increases the workload of the staff, but also reduces the efficiency of spraying. Utility Model Content

[0004] The purpose of this invention is to provide an automated spraying device for rubber shoe materials to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an automated spraying device for rubber shoe materials, comprising a first frame and a second frame arranged front and rear, a first conveyor belt above the first frame, a second conveyor belt above the second frame, the height of the first conveyor belt being higher than the height of the second conveyor belt, a spraying component and a coating component above both the first and second conveyor belts, a third frame between the first and second frames, a rotatable ladder plate above the first frame, the upper end of the ladder plate extending upward at an incline and connecting to the rear end of the first conveyor belt, a control motor for controlling the rotation of the ladder plate on the frame, the ladder plate deflecting downwards and connecting to the front end of the second conveyor belt, a light sensing component at the upper end of the ladder plate; and a controller and a signal processor, the light sensing component being electrically connected to the signal processor, and the light sensing component, the control motor, and the signal processor all being electrically connected to the controller.

[0006] Using the above technical solution, the rubber shoe material is placed above the front end of the first conveyor belt. The first conveyor belt moves the rubber shoe material forward. The rubber shoe material first passes through the spraying component to be coated, then passes through the coating component. Next, the rubber shoe material passes through the rear end of the first conveyor belt to the top of the ladder plate. After the light sensor detects the rubber shoe material, it sends a signal to the signal processor. The signal processor converts the signal and sends it to the controller. The controller controls the motor to rotate, thereby causing the ladder plate to deflect downwards. After the ladder plate rotates, it presses the rubber shoe material above the front end of the second conveyor belt, realizing the flipping of the rubber shoe material. Then, the controller causes the motor to rotate, causing the ladder plate to deflect upwards and reconnect with the rear end of the first conveyor belt. Then, the second conveyor belt moves the rubber shoe material forward, and the rubber shoe material passes through the spraying component to be coated again, then passes through the coating component. This achieves double-sided spraying of the rubber shoe material without the need for manual flipping by workers. At the same time, the coating component can also spread the coating evenly on the surface of the rubber shoe material, reducing the workload of workers and improving the efficiency of spraying.

[0007] As a further optimization of this utility model, a pair of side plates are provided on both sides above the first frame and the second frame, and a top plate is connected above the pair of side plates. The spraying assembly includes a spraying plate installed below the top plate, and a plurality of nozzles are provided at the bottom of the spraying plate.

[0008] As a further optimization of this utility model, the top plate is provided with a paint box, a delivery pump and a fixed pipe inserted into the top plate, the top of the spraying plate is connected to the bottom of the fixed pipe, the input end of the delivery pump is connected to the paint box and the output end is connected to the fixed pipe.

[0009] Using the above technical solution, the delivery pump extracts the paint liquid from the paint box and sends it to the fixed pipe. The fixed pipe then delivers the paint to the spraying plate and sprays it from the nozzle onto the rubber shoe material.

[0010] As a further optimization of this utility model, a pair of side plates are provided on both sides of the upper part of the first frame and the second frame, and a top plate is connected above the pair of side plates. The coating component includes a cylinder and a brush plate. The cylinder is installed above the top plate, and the movable end of the cylinder passes downward through the top plate and connects to the top of the brush plate. The bottom of the brush plate is provided with bristles.

[0011] Using the above technical solution, the extended end of the cylinder causes the brush plate to move downward. When the rubber shoe material after being sprayed with paint moves backward, it comes into contact with the brush bristles, and the brush bristles spread the paint evenly on the surface of the rubber shoe material.

[0012] As a further optimization of this utility model, a negative pressure chamber is provided on the inner side above the ladder plate, and an air hole communicating with the negative pressure chamber is provided on the surface of the ladder plate; it also includes a hose, one end of which is connected to the negative pressure chamber and the other end is connected to a negative pressure air pump, and the negative pressure air pump is electrically connected to the controller.

[0013] Using the above technical solution, after the light sensor detects the rubber shoe material, it sends a signal to the signal processor. The signal processor converts the signal and sends it to the controller. The controller controls the negative pressure air pump to draw in air, thereby creating negative pressure in the negative pressure chamber. This causes the air holes to generate suction, which adsorbs the rubber shoe material. When the controller drives the ladder plate to descend and deflect and connect with the second conveyor belt, the controller controls the negative pressure air pump to discharge air, thereby eliminating the negative pressure in the negative pressure chamber and releasing the rubber shoe material from the second conveyor belt.

[0014] The beneficial effects of this utility model are as follows: The rubber shoe material is placed above the front end of the first conveyor belt. The first conveyor belt drives the rubber shoe material forward. The rubber shoe material first passes through a spraying component to be coated, then passes through a coating component. Next, the rubber shoe material passes through the rear end of the first conveyor belt to the top of the ladder plate. A light sensor detects the rubber shoe material and sends a signal to a signal processor. The signal processor converts the signal and sends it to a controller. The controller controls a motor to rotate, causing the ladder plate to deflect downwards. After the ladder plate rotates, it presses the rubber shoe material above the front end of the second conveyor belt, thus flipping the rubber shoe material. Then, the controller causes a motor to rotate, causing the ladder plate to deflect upwards and reconnect with the rear end of the first conveyor belt. The second conveyor then drives the rubber shoe material forward again, and the rubber shoe material passes through the spraying component to be coated again, then passes through the coating component. This achieves double-sided spraying of the rubber shoe material without requiring manual flipping by workers. Simultaneously, the coating component evenly coats the surface of the rubber shoe material, reducing the workload of workers and improving spraying efficiency. Attached Figure Description

The top plate 24 is provided with a paint box, a delivery pump 42 and a fixed pipe 31 inserted into the top plate 24. The top of the spraying plate 32 is connected to the bottom of the fixed pipe 31. The input end of the delivery pump 42 is connected to the paint box and the output end is connected to the fixed pipe 31. The coating assembly includes a cylinder 51 and a brush plate 52. The cylinder 51 is installed above the top plate 24. The movable end of the cylinder 51 passes downward through the top plate 24 and is connected to the top of the brush plate 52. The bottom of the brush plate 52 is provided with bristles 53.

[0019] A third frame is provided between the first frame 11 and the second frame 12. A rotatable ladder plate 7 is provided above the frame, and a rotating shaft 61 is provided above the frame. The lower end of the ladder plate 7 is circumferentially fixed to the rotating shaft 61.

[0020] The upper end of the ladder plate 7 extends upward at an angle and connects to the rear end of the first transmission belt. A control motor 62 for controlling the rotation of the ladder plate 7 is provided on the frame. The output end of the control motor 62 is connected to the rotating shaft 61. After the ladder plate 7 deflects downward, it can connect to the front end of the second transmission belt 22. A light sensing component 8 is provided at the upper end of the ladder plate 7. The light sensing component 8 is an infrared emitter and an infrared receiver. It also includes a controller and a signal processor. The light sensing component 8 is electrically connected to the signal processor. The light sensing component 8, the control motor 62, and the signal processor are all electrically connected to the controller.

[0021] A negative pressure chamber 71 is provided on the inner side above the ladder plate 7, and an air hole 72 communicating with the negative pressure chamber 71 is provided on the surface of the ladder plate 7; it also includes a hose 9, one end of which is connected to the negative pressure chamber 71 and the other end is connected to a negative pressure air pump, which is electrically connected to the controller.

[0022] The principle of this utility model is as follows: rubber shoe material is placed above the front end of the first conveyor belt 21. The first conveyor belt 21 moves the rubber shoe material forward. The rubber shoe material is first sprayed with a coating by the spraying component: the delivery pump 42 extracts the paint liquid in the paint box and sends it to the fixed pipe 31. The fixed pipe 31 sends the paint to the spraying plate 32 and then sprays it from the nozzle 33, spraying the paint onto the rubber shoe material.

[0023] Next, the coating component extends the movable end of the cylinder 51, causing the brush plate 52 to move down. When the rubber shoe material after being sprayed with paint moves backward, it comes into contact with the brush bristles 53, and the brush bristles 53 spread the paint evenly on the surface of the rubber shoe material.

[0024] Next, the rubber shoe material passes the rear end of the first conveyor belt 21 and arrives at the upper end of the ladder plate 7. After the light sensor component 8 detects the rubber shoe material, it sends a signal to the signal processor. The signal processor converts the signal and sends it to the controller. The controller controls the motor 62 to rotate, thereby driving the ladder plate 7 to descend and deflect. At the same time, the controller controls the negative pressure air pump to draw in air, thereby generating negative pressure in the negative pressure chamber 71, causing the air hole 72 to generate suction and adsorb the rubber shoe material.

[0025] After the ladder plate 7 rotates, it presses the rubber shoe material onto the front end of the second conveyor belt 22, thus turning the rubber shoe material over. At the same time, the controller controls the negative pressure air pump to release air, thereby eliminating the negative pressure in the negative pressure chamber 71 and releasing the rubber shoe material onto the second conveyor belt 22.

[0026] Then the controller causes the control motor 62 to rotate, driving the ladder plate 7 to move upward and deflect, reconnecting with the rear end of the first conveyor belt 21. Then the second conveyor belt 22 moves the rubber shoe material forward, and the rubber shoe material passes through the spraying assembly again to be sprayed with a coating: the delivery pump 42 draws out the paint liquid in the paint box and sends it to the fixed pipe 31. The fixed pipe 31 sends the paint to the spraying plate 32 and then sprays it from the nozzle 33, spraying the paint onto the rubber shoe material.

[0027] Next, the coating component extends the movable end of the cylinder 51, causing the brush plate 52 to move down. When the rubber shoe material after being sprayed with paint moves backward, it comes into contact with the brush bristles 53, and the brush bristles 53 spread the paint evenly on the surface of the rubber shoe material.

[0028] This allows for double-sided spraying of rubber shoe materials without the need for manual flipping by workers. At the same time, the coating component can evenly coat the paint on the surface of the rubber shoe materials, reducing the workload of workers and improving the efficiency of spraying.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
