Description

Technical Field

[0001] This utility model relates to a device for solving the problem of material residue during unloading of a pagoda-type coating machine, especially for fluidized bed coating machines, and belongs to the fields of feed additives, pharmaceuticals, chemicals, materials, and food equipment. Background Technology

[0002] The pagoda-type coating machine is one of the commonly used coating machines in the feed additive industry, but problems still exist in its use. Due to the special layered structure of the pagoda-type chassis, a lot of material remains inside the pagoda during unloading. On the one hand, the residual material is blown out by the opening of the exhaust fan during the next batch of coating, mixing into the new material for re-coating, and this cycle repeats, resulting in uneven particle content and seriously affecting product quality. On the other hand, after coating, the pagoda needs to be manually dismantled layer by layer to manually clean the residual material and then wash it, which seriously affects the cleaning efficiency and brings great inconvenience to the cleaning process. Currently, there are two main measures to solve the problem of incomplete unloading of pagoda-type coating machines: 1. Repeatedly opening and closing the flap to allow the material to fall off as cleanly as possible. This method cannot completely solve the problem of material residue inside the pagoda and also affects production efficiency (each opening and closing of the flap takes about 3 minutes) and the service life of the flap. 2. Asking the equipment manufacturer to enlarge the ventilation holes around each layer of the pagoda to facilitate material falling off. This method cannot completely solve the problem of material residue inside the pagoda; about 3% of the material remains. Utility Model Content

[0003] To address the aforementioned problems, the present invention aims to provide a device for resolving material residue issues during unloading of a pagoda-type coating machine. The structural design of this invention can solve the problem of incomplete material cleaning during unloading in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A device for resolving material residue during unloading of a pagoda-type coating machine is characterized by comprising a sliding mechanism disposed on the inner side of the coating cylinder wall, a spray gun disposed on the sliding mechanism, the spray gun sliding below a ventilation chassis under the action of the sliding mechanism, the pagoda being disposed above the ventilation chassis and communicating with the ventilation chassis, and the residual material in the pagoda being cleaned up during the sliding process.

[0006] The sliding mechanism includes a telescopic rod, which is installed on the inner wall of the coating cylinder, and one end of the telescopic part is connected to the spray gun, thereby realizing the up and down sliding of the spray gun. The telescopic rod is driven by a cylinder.

[0007] Furthermore, it also includes a sliding table device, which is horizontally installed on the inner side of the coating cylinder wall. The sliding table device includes a slide rail, a lead screw is installed on the slide rail, a nut is installed on the lead screw, and the nut is fixedly connected to the slider. The slider is connected to one side of the fixed part of the telescopic rod, thereby realizing the left and right sliding of the telescopic rod, and thus realizing the up, down, left and right sliding of the spray gun.

[0008] The sliding mechanism includes a slide plate device, which is vertically installed on the inner side of the coating cylinder wall. The slide plate device includes a slide rail, a lead screw is installed on the slide rail, a nut is installed on the lead screw, and the nut is fixedly connected to the slider. The slider is connected to the spray gun, thereby realizing the up and down sliding of the spray gun.

[0009] Furthermore, it also includes a horizontal slide device. The slide rail of the horizontal slide device is installed on the slider of the vertical slide device, and the spray gun is installed on the slider of the horizontal slide device. By controlling the movement of the sliders of the two slide devices, the spray gun can be moved up, down, left, and right.

[0010] Furthermore, the spray angle of the spray gun is 0°-60°.

[0011] Furthermore, there are four spray guns, which are installed horizontally and parallelly on the spray gun fixing component, which is arc-shaped.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] Compared with the first existing method, the present invention can completely clean up the residual material in just 1 minute, without affecting production efficiency, and the equipment performance will not be affected by the repeated opening and closing of the flap.

[0014] Compared with the second existing method, the method used in this utility model does not require enlarging the ventilation holes of each layer of the pagoda, thus not affecting the stable fluidization of the material and ensuring product quality; at the same time, it can also clean all the residual material inside the pagoda.

[0022] The present invention will now be described in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] The present invention provides a device for resolving material residue during unloading of a pagoda-type coating machine, which can adopt the following solution:

[0024] like Figure 3 As shown, in this embodiment, the sliding mechanism includes a telescopic rod 6, which is installed on the inner wall of the coating tube. One end of the telescopic part is connected to the spray gun fixing member 11, and a spray gun 12 is connected to the spray gun fixing member 11. The telescopic rod 6 is driven by a cylinder. After compressed gas is introduced, the piston inside the telescopic rod 6 moves to push out the telescopic part. After the compressed gas is discharged, the telescopic part retracts. The up and down sliding of the spray gun 12 is controlled by the piston movement inside the cylinder.

[0025] like Figure 3 , 4 As shown, it further includes a sliding table device 7, which is horizontally installed inside the coating cylinder wall 14. The sliding table device 7 includes a slide rail 8, a lead screw 9 is mounted on the slide rail 8, and a nut is mounted on the lead screw 9. The nut is fixedly connected to the slider 10, and the slider 10 is connected to one side of the fixed part of the telescopic rod 6. The sliding table device 7 is driven by a motor. The output shaft of the motor is connected to the lead screw 9 through a coupling. The rotational motion of the lead screw 9 is converted into the linear motion of the slider 10 using the principle of a ball screw, thereby driving the telescopic rod 6 to slide left and right. This enables the spray gun 12 to slide up, down, left, and right.

[0026] like Figure 4As shown, in another embodiment, the sliding mechanism adopts a sliding table device 7, which is vertically installed on the inner side of the coating cylinder wall. The sliding table device 7 includes a slide rail 8, a lead screw 9 is provided on the slide rail 8, a nut is provided on the lead screw 9, and the nut is fixedly connected to the slider 10. The slider 10 is connected to the spray gun 12 through the spray gun fixing part 11. The output shaft of the motor is connected to the lead screw 9 through a coupling. The rotational motion of the lead screw 9 is converted into the linear motion of the slider 10 by utilizing the principle of the ball screw, thereby driving the spray gun 12 to slide up and down.

[0027] like Figure 5 As shown, it further includes a horizontal slide device. The slider 10 of the vertical slide device 7 is vertically and fixedly connected to the slide rail 8 of the horizontal slide device 7. The horizontal slide device 7 is driven by a motor. The output shaft of the motor is connected to the lead screw 9 through a coupling. The rotational motion of the lead screw 9 is converted into the linear motion of the slider 10 by utilizing the principle of the ball screw. A spray gun 12 is connected to the horizontally installed slider 10 through a spray gun fixing part 11. The spray gun 12 slides left and right under the drive of the slider 10.

[0028] Additional explanation: The horizontal slide device here has the same structure as the vertical slide device. In this embodiment, the cross slide device is formed by adopting a vertical fixing method.

[0029] Furthermore, the spray gun 12 slides left and right on the horizontal slide device 7, and the horizontal slide device 7 slides up and down on the vertical slide device 7. Through synchronous control, the spray gun 12 can slide up, down, left and right.

[0030] like Figure 1 As shown, in this embodiment, four spray guns 12 are used. The four spray guns 12 are fixed horizontally and parallelly in the holes of the spray gun fixing member 11. Furthermore, the spray gun fixing member 11 is arc-shaped, consistent with the inner wall of the coating machine cylinder wall 14, and its length is half of the coating machine cylinder wall 14. The spray gun fixing member 11 is fixed on the slider 10 of the horizontal slide device 7.

[0031] Installation of compressed air pipe: First, make a small hole in the wall of the unloading hopper 15 and connect the compressed air pipe 13. Use a compressed air adapter to connect the four spray guns 12.

[0032] Compressed gas is introduced into the tail of the spray gun 12. It is equipped with a spring and a pin inside. When compressed gas is introduced, the spring is deformed, which drives the pin to retract, thereby blowing the pagoda ventilation chassis 1. When compressed gas is not introduced, the spring is not compressed, and the pin is tightly fitted with the nozzle of the spray gun to prevent fine powder and coating liquid oil powder from entering the inside of the spray gun 12.

[0033] The spray gun can refer to the spray guns described in patent numbers CN201520906931.8 and CN202221679840.1. The compressed gas introduced into the spray gun 10 needs to be filtered and dried to remove impurities and moisture from the air. The purpose is to keep the air inside the coating machine pure and prevent impurities from appearing in the subsequent coating process, which would affect the production quality.

[0034] like Figure 1 As shown, after the coating machine finishes coating, the central shaft 5 drives the ventilation chassis 1 to slowly rotate to 90 degrees to begin unloading. Once the sensor detects that the pagoda chassis is at a 90-degree angle, it controls the solenoid valve to open, allowing compressed air to be introduced through the compressed air pipe 13 into the spray gun 12. At this moment, the pressure inside the spray gun 12 increases instantaneously, and the spring contracts under pressure, causing the ejector pin to retract, creating a channel for compressed air to spray onto the bottom mesh of the ventilation chassis 1. The four spray guns 12 are positioned at 45°, spraying upwards at an angle. Simultaneously, the drive motor drives the lead screw 9 to rotate, using the ball screw principle to convert the rotational motion into linear motion of the slider. The vertical slide device drives the spray gun 12 to slide up and down, while the cross slide device drives the spray gun 12 to slide left, right, and up and down. The sprayed material falls from the ventilation holes of each pagoda layer into the unloading bin 15. After the spraying is completed, slider 10 returns to its initial position, and the solenoid valve automatically closes. With no pressure remaining in the spray gun 12, the spring extends and returns to its natural shape, causing the ejector pin to spring back to the spray gun nozzle, completing one cycle. After large-scale production testing, the spray gun blows upwards at a 45° angle while the spray gun 12 slides up, down, left, and right, achieving all-around spraying for one minute, which is sufficient to completely clean the residual material inside the pagoda.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
