Description

Technical Field

[0001] This utility model relates to the field of quick nozzle disassembly technology, and in particular to a quick disassembly device for post-coating nozzles. Background Technology

[0002] Feed processing machines are a common type of processing equipment. With the development of technology, the technology of spraying liquid enzyme preparations and animal and vegetable oils on the surface of feed pellets after pelleting is gradually being adopted to avoid the enzyme proteins from being damaged and losing their biological functions. This is known as post-coating technology.

[0003] Currently, each post-coating machine has four built-in fan-shaped nozzles with a diameter of 0.8mm. When the nozzles are clogged by oil impurities, or when there are abnormalities in the spraying or when the nozzles need to be replaced, a wrench needs to be inserted into the spraying chamber. Due to the limited space in the spraying chamber, it is not convenient to observe. Therefore, the four nozzles can only be removed and inspected by feeling with the wrench. It is calculated that it takes 11 minutes to remove the four nozzles, and one person is also needed to hold a flashlight. The entire removal process requires two people to work together, which makes nozzle replacement and maintenance time-consuming and laborious.

[0004] Therefore, in order to solve the above problems, there is an urgent need for a quick disassembly device for the post-coating nozzle. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick disassembly device for the post-coating nozzle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The quick-release device for the rear spray nozzle includes a movable plate disposed on one side of the rear spray equipment body. A set of connecting pipes is fixed to the outer wall of one side of the movable plate. One end of the connecting pipe is connected to a tee. One end of the tee is provided with a DN15 quick connector. One end of the DN15 quick connector is provided with a spray pipe. A set of locking blocks is fixed to the outer wall of the movable plate. A U-shaped frame is locked to the inner wall of the locking blocks. A set of fixing plates is fixed to the outer wall of the rear spray equipment body. A connecting block is fixed to the outer wall of the fixing plates. A connecting plate is rotatably connected to the outer wall of the connecting blocks. A fixing block is fixed to one end of the connecting plate. A connecting post is inserted into the inner wall of the fixing block. The U-shaped frame is inserted into the inner wall of the connecting post.

[0008] As a further improvement of this utility model, a handle is fixed to the outer wall of the fixing block.

[0009] As a further improvement of this utility model: a set of nozzles is provided on one side of the outer wall of the movable plate, and the nozzles are connected to the connecting pipe.

[0010] As a further improvement of this utility model: the outer wall of the U-shaped frame has external threads, and a set of locking nuts are connected to the outer wall of the external threads by threads, with the locking nuts located on both sides of the connecting column.

[0011] As a further improvement of this utility model, a set of positioning screws is fixed on one side of the outer wall of the post-coating equipment body.

[0012] As a further improvement of this utility model: a set of positioning holes are opened on the outer wall of the movable plate, and positioning screws are inserted into the inner wall of the positioning holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. First, pry open the pull rings on both sides of the DN15 quick connector outwards. Then, pull the DN15 quick connector out from the tee side and pull the spray nozzle out from the moving plate side. Next, pry open the handles on both sides of the moving plate outwards. When the handles are turned outwards, the U-shaped frame fixed to the outer wall of the connecting column will move forward, allowing one side of the U-shaped frame to move out from the inner wall of the locking block. Then, the moving plate can be pulled out from the spray chamber side. Quickly remove the moving plate and a set of nozzles on one side from between the spray chamber and the spray nozzle. This improves the efficiency of nozzle maintenance and replacement of the subsequent spraying equipment and makes it convenient for staff to replace different types of nozzles according to spraying needs.

[0015] 2. The two positioning screws located on one side of the moving plate can be inserted into the two positioning holes on the outer wall of the moving plate. During installation, the moving plate can be guided and limited, thereby quickly positioning the moving plate and improving the accuracy of nozzle installation of the subsequent spraying equipment.

[0025] Example 1

[0026] Post-coating nozzle quick-release device, such as Figure 1-4 As shown, the device includes a movable plate 1 disposed on one side of the main body 16 of the rear spraying equipment. A set of connecting pipes 6 are fixed to the outer wall of one side of the movable plate 1. One end of the connecting pipes 6 is connected to a tee 5. One end of the tee 5 is provided with a DN15 quick connector 4. One end of the DN15 quick connector 4 is provided with a spray pipe 3. A set of locking blocks 7 are fixed to the outer wall of the movable plate 1. A U-shaped frame 8 is locked to the inner wall of the locking blocks 7. A set of fixing plates 14 are fixed to the outer wall of the main body 16 of the rear spraying equipment. A connecting block 2 is fixed to the outer wall of the fixing plates 14. A connecting plate 9 is rotatably connected to the outer wall of the connecting block 2. A fixing block 19 is fixed to one end of the connecting plate 9. A connecting post 13 is inserted into the inner wall of the fixing block 19. The U-shaped frame 8 is inserted into the inner wall of the connecting post 13.

[0027] A handle 10 is fixed to the outer wall of the fixing block 19;

[0028] A set of nozzles 20 is provided on one side of the outer wall of the movable plate 1, and the nozzles 20 are connected to the connecting pipe 6;

[0029] The outer wall of the U-shaped frame 8 has an external thread 11, and a set of locking nuts 12 are connected to the outer wall of the external thread 11 by thread. The locking nuts 12 are located on both sides of the connecting column 13.

[0030] A set of positioning screws 15 are fixed to one side of the outer wall of the post-spraying equipment body 16;

[0031] The outer wall of the movable plate 1 has a set of positioning holes 18, and the positioning screws 15 are inserted into the inner wall of the positioning holes 18.

[0032] When the operator needs to remove the nozzle 20 inserted on one side of the spray chamber 17 for maintenance and replacement, first, pry open the pull rings on both sides of the DN15 quick connector 4 to release the DN15 quick connector 4 from the T-junction 5. Then, pull the DN15 quick connector 4 out from the T-junction 5 to pull the spray pipe 3 out from the moving plate 1. Next, pry open the handles 10 on both sides of the moving plate 1. When the handles 10 are turned outward, they will drive the U-shaped frame 8 fixed to the outer wall of the connecting column 13 to move forward as a whole, so that one side of the U-shaped frame 8 moves out from the inner wall of the locking block 7, releasing the U-shaped frame 8 from the locking block 7. Then, the moving plate 1 can be pulled out from one side of the spray chamber 17, so that the moving plate 1 and a set of nozzles 20 on one side can be quickly removed from the spray chamber 17 and the spray pipe 3. This reduces the nozzle removal time to less than ten seconds, improves the efficiency of nozzle maintenance and replacement of the subsequent spraying equipment, and makes it convenient for the operator to replace different models of nozzles according to the spraying needs.

[0033] The distance between the U-shaped frame 8 and the fixed block 19 can be adjusted by rotating the locking nut 12, thereby adjusting the tightness of the U-shaped frame 8 fastened to the side of the clip block 7. This allows the quick disassembly device to be installed on the side of the moving plate 1 and the rear spraying equipment body 16 of different sizes, improving the applicability of the quick disassembly device.

[0034] Meanwhile, the two positioning screws 15 located on one side of the moving plate 1 can be inserted into the two positioning holes 18 on the outer wall of the moving plate 1. During installation, the moving plate 1 can be guided and limited, thereby quickly positioning the moving plate 1 and improving the accuracy of nozzle installation of the subsequent spraying equipment.

[0035] The DN15 quick connector 4 used in this embodiment is a commercially available and mature pipe connector. It is a mature technology, and its specific working principle and structure will not be described in detail here.

[0036] Working principle: Pry open the pull rings on both sides of the DN15 quick connector 4 outwards, then pull the DN15 quick connector 4 out from the side of the tee 5, pull the spray pipe 3 out from the side of the moving plate 1, and then pry open the handles 10 on both sides of the moving plate 1 outwards. When the handles 10 are turned outwards, the U-shaped frame 8 fixed to the outer wall of the connecting column 13 will move forward as a whole, allowing one side of the U-shaped frame 8 to move out from the inner wall of the locking block 7, releasing the U-shaped frame 8 from the locking block 7. Then the moving plate 1 can be pulled out from one side of the spray chamber 17, thereby quickly disassembling the moving plate 1 and a set of nozzles 20 on one side from the spray chamber 17 and the spray pipe 3.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
