Description

Technical Field

[0001] This invention relates to the field of coating machine technology, and in particular to a coating machine with intelligently adjustable spray gun and its usage method. Background Technology

[0002] A high-efficiency coating machine is a highly efficient, energy-saving, safe, and clean mechatronic device capable of organic film coating, water-soluble film coating, and sustained-release / controlled-release coating of tablets, pills, and candies. The spray gun is mounted on a spray gun holder, which in turn is mounted on the coating machine's mounting shaft. Currently, during the coating process, as the tablet's flowability changes and process parameters are adjusted, the tablet bed angle changes. To ensure sufficient contact between the atomized slurry and the tablet and to guarantee the atomization effect, the spray gun angle needs to be adjusted during the coating process.

[0003] The applicant's earlier patent application, with publication number CN 218637736U, disclosed a multi-functional spray gun holder structure for a coating machine, including a spray gun holder and a spray gun. The spray gun is set on the spray gun holder, and a distance adjustment and angle adjustment structure is provided between the spray guns. However, this adjustment structure needs to be made inside the coating machine, which is difficult to adjust. During adjustment, the bolts are also prone to falling into the tablets, causing the medicine to be contaminated. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the adjustment structure needs to be performed inside the coating machine, making adjustment difficult and causing bolts to easily fall into the tablets and contaminate the medicine. The invention proposes a coating machine with an intelligently adjustable spray gun and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coating machine with an intelligently adjustable spray gun and its usage method include a fixed rod, a bracket set on the fixed rod, a spray gun set on the bracket, and a fixed plate set inside the coating machine. A worm gear reducer is fixedly mounted on one side of the fixed plate, and the fixed rod is fixedly mounted on the output end of the worm gear reducer.

[0007] It also includes a coupling that is rotatably mounted on one side of the coating machine. One end of the coupling located outside the coating machine is provided with a rotating handle, and the other end of the coupling is connected to the input end of the worm gear reducer. The rotating handle can drive the output end of the worm gear reducer to rotate, thereby adjusting the angle of the spray gun.

[0008] A positioning mechanism is installed on the rotary handle for connection with the coupling, which facilitates connection to the coupling and limits the position of the rotary handle.

[0009] An adjustment mechanism, located on the turbine reducer, is used to further adjust the angle between the spray guns, thereby improving the flexibility of adjustment.

[0010] In one possible design, the positioning mechanism includes a first positioning plate fixedly sleeved on the rotating handle, and a second positioning plate provided on the outer side of the coating machine body. The first positioning plate has a first positioning hole, and the second positioning plate has a plurality of second positioning holes along the rotation trajectory of the first positioning hole. A positioning element is provided in the first positioning hole and one of the second positioning holes.

[0011] In one possible design, the adjusting mechanism includes an internal gear ring fixedly sleeved on one side of the output end of the worm gear reducer, a connecting block sleeved on the output end of the worm gear reducer, a fixed rod sleeved on the output shaft, a rotating block rotatably mounted on the inner wall of the connecting block, the fixed rod passing through and fixedly mounted inside the rotating block, and a gear meshing with the internal gear ring fixedly sleeved on the rotating shaft of the rotating block.

[0012] In one possible design, the fixed rod is provided with a connecting ring, and a distance scale line section is provided on the end of the fixed rod away from the worm gear reducer. The bracket is connected to the distance scale line section through the connecting ring.

[0013] In one possible design, a fixed shaft is provided through one side of the output end of the worm gear reducer. One end of the fixed shaft is connected to a coating machine. The top of the connecting block has a sliding groove coaxial with the output shaft of the worm gear reducer. A third electromagnet ring and a fourth electromagnet ring are provided in the sliding groove. The third electromagnet ring is fixedly sleeved on the output end of the worm gear reducer, and the fourth electromagnet ring is slidably disposed in the sliding groove. The attraction between the third and fourth electromagnet rings can fix the connecting block to the output shaft of the worm gear reducer. The repulsion between the third and fourth electromagnet rings causes the fourth electromagnet ring to abut against the fixed shaft, thereby fixing the connecting block.

[0014] In one possible design, the end of the coupling extending outside the coating machine is flush with the outer wall of the coating machine and is provided with a connecting groove. The end of the rotating handle facing the connecting groove is provided with a matching connecting protrusion. When the connecting protrusion is inserted into the connecting groove, the coupling and the rotating handle rotate synchronously.

[0015] In one possible design, the rotating handle includes a first rod portion arranged in a straight line with the coupling, a second rod portion arranged perpendicular to the first rod portion, and a third rod portion arranged perpendicular to the second rod portion and in a direction away from the spray gun, wherein an operating sleeve is provided on the third rod portion.

[0016] A method for using a coating machine with an intelligently adjustable spray gun includes the following steps:

[0017] S1. First, insert the rotating handle into the coupling and rotate the rotating handle to drive the output end of the turbine reducer to rotate. Then, start the third and fourth electromagnet rings so that they attract each other and fix the connecting block on the output end of the turbine reducer. At this time, the rotation of the output end of the turbine reducer can drive the connecting block to rotate, and adjust the angle of the spray gun.

[0018] S2. When further adjustment is required, activate the third and fourth electromagnet rings to fix the connecting block, and then drive the internal gear ring to rotate. Through the gears and the internal gear ring, the fixing rod rotates on the connecting block to further adjust the angle of the spray gun.

[0019] S3. After adjustment, rotate the positioning piece through the first positioning hole and the second positioning hole to fix the rotating handle.

[0020] S4. When it is necessary to remove the rotating handle, remove the positioning piece from the first positioning plate, and then the rotating handle can be removed from the coupling.

[0021] In this application, the rotating handle is first inserted into the coupling and rotated. The coupling drives the worm gear reducer to work, causing the output end of the worm gear reducer to rotate. At the same time, the third and fourth electromagnet rings are activated and attracted to each other, causing the fourth electromagnet ring to be fixed to the third electromagnet ring. The connecting block is fixed to the output end of the worm gear reducer. At this time, the rotation of the output end of the worm gear reducer can drive the connecting block to rotate, thus adjusting the angle of the spray gun.

[0022] When further adjustment is needed, activate the third and fourth electromagnet rings to release the fixing of the connecting block, so that the connecting block is fixedly connected to the fixed shaft. Then, turn the handle to drive the worm gear reducer to work, drive the output end of the worm gear reducer to rotate, drive the internal gear ring to rotate. During the rotation, the gear and internal gear ring drive the fixed rod to rotate on the connecting block, further adjusting the angle of the spray gun.

[0023] After adjustment, rotate the positioning piece through the first positioning hole and the second positioning hole (101) to fix the rotating handle;

[0024] When it is necessary to remove the rotating handle, remove the positioning piece from the first positioning plate, at which point the rotating handle can be removed from the coupling.

[0025] In this invention, the coating machine with intelligent adjustable spray gun can not only fix the rotating handle on the coupling through the setting of the positioning mechanism, but also fix the rotating handle to the coating machine, limit the rotating handle, and lock it after the adjustment is completed so that it will not be rotated by external force.

[0026] In this invention, the coating machine with an intelligent adjustable spray gun can further adjust the angle between the fixing rod and the connecting block through the setting of the adjustment mechanism, making the angle adjustment more flexible and allowing for different angle adjustments. After adjustment, the connecting block can be further fixed by the third and fourth electromagnet rings, making it more stable.

[0027] In this invention, the spray gun angle can be adjusted outside the coating machine without affecting the normal operation of the coating machine. At the same time, the positioning component can position the rotating handle after the spray gun angle adjustment is completed, preventing the rotating handle from rotating unexpectedly and affecting the accuracy of the spray gun.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1

[0038] Reference Figures 1-7 A coating machine with intelligently adjustable spray gun and its usage method, applicable in the field of coating machines, including: Figure 1 As shown, the coating machine with intelligent adjustable spray gun in this embodiment includes a fixed rod 1, a bracket 2 set on the fixed rod 1, a spray gun 3 set on the bracket 2, and a fixed plate 8 set inside the coating machine. A turbine reducer 4 is fixedly provided on one side of the fixed plate 8, and the fixed rod 1 is fixedly provided on the output end of the turbine reducer 4.

[0039] It also includes a coupling 5 that is rotatably mounted on one side of the coating machine. One end of the coupling 5 located outside the coating machine is equipped with a rotating handle 6. The other end of the coupling 5 is connected to the input end of the turbine reducer 4. The rotating handle 6 can drive the output end of the turbine reducer 4 to rotate, thereby adjusting the angle of the spray gun 3.

[0040] A positioning mechanism is provided on the rotating handle 6 for connection with the coupling 5, which facilitates connection to the coupling 5 and limits the rotation handle 6.

[0041] The adjustment mechanism, set on the turbine reducer 4, is used to further adjust the angle between the spray guns 3, which can improve the adjustment flexibility. By rotating the rotating handle 6, the turbine reducer 4 can be driven to work. During the operation, the fixed rod 1 can be driven to rotate through the output shaft, thereby driving the spray gun 3 to adjust the angle. The spray angle of the spray gun 3 can be further adjusted through the hinge mechanism, so that it can rotate flexibly. The rotating handle 6 is connected to the coupling 5 through the positioning mechanism, so that the rotating handle 6 can be removed when adjustment is not needed, which can effectively prevent external force from rotating the rotating handle 6.

[0042] The positioning mechanism includes a first positioning plate 9 fixedly sleeved on the rotating handle 6, and a second positioning plate 10 provided on the outer side of the coating machine body. The first positioning plate 9 has a first positioning hole 91, and the second positioning plate 10 has a plurality of second positioning holes 101 along the rotation trajectory of the first positioning hole 91. A positioning element 11 is provided in the first positioning hole 91 and one of the second positioning holes 101. The positioning element 11 can position the rotating handle 6 after the spray gun 3 angle is adjusted, preventing the rotating handle 6 from rotating accidentally and affecting the accuracy of the spray gun 3. The area of ​​the first positioning plate 9 gradually decreases along the direction from the rotating handle 6 to the first positioning hole 91, which can save materials and is more intuitive during operation, making it easier for the positioning element 11 to be fitted with the two positioning holes. The positioning element 11 can be a bolt or a pin, and the positioning holes 101 are designed for compatibility.

[0043] The adjustment mechanism includes an internal gear ring 18 fixedly sleeved on one side of the output end of the worm gear reducer 4, a connecting block 14 sleeved on the output end of the worm gear reducer 4, a fixed rod 1 sleeved on the output shaft, a rotating block 16 rotatably mounted on the inner wall of the connecting block 14, and the fixed rod 1 passing through and fixedly mounted inside the rotating block 16. A gear 17 meshing with the internal gear ring 18 is fixedly sleeved on the rotating shaft of the rotating block 16. By rotating the rotating handle 6, the output end of the worm gear reducer 4 can be rotated, which can drive the connecting block 14 to rotate. In the process of rotating the connecting block 14, the fixed rod 1 rotates. At the same time, in the process of rotating the fixed rod 1, the fixed rod 1 can be driven to rotate on the connecting block 14 through the gear 17 and the internal gear ring 18, so that the adjustment is flexible.

[0044] A fixed shaft 15 is provided through one side of the output end of the worm gear reducer 4. One end of the fixed shaft 15 is connected to the coating machine. The top of the connecting block 14 has a sliding groove 21 coaxial with the output shaft of the worm gear reducer 4. A third electromagnet ring 22 and a fourth electromagnet ring 23 are provided in the sliding groove 21. The third electromagnet ring 22 is fixedly sleeved on the output end of the worm gear reducer 4, and the fourth electromagnet ring 23 is slidably disposed in the sliding groove 21. The attraction between the third electromagnet ring 22 and the fourth electromagnet ring 23 can fix the connecting block 14 to the output shaft of the worm gear reducer 4. The repulsion between the third electromagnet ring 22 and the fourth electromagnet ring 23 causes the fourth electromagnet ring 23 to abut against the fixed shaft 15, thereby abutting the connecting block 14. The connection block 14 is fixed to the output shaft of the worm gear reducer 4 by activating the third electromagnet ring 22 and the fourth electromagnet ring 23, which attract each other and allow the connection block 14 to rotate. When the third electromagnet ring 22 and the fourth electromagnet ring 23 are activated, they repel each other, which causes the fourth electromagnet ring 23 to abut against the fixed shaft 15. This releases the connection block 14 from the output shaft of the worm gear reducer 4 and fixes the connection block 14 to the fixed shaft 15. This prevents the connection block 14 from rotating when the output shaft of the worm gear reducer 4 rotates, and allows the output shaft of the worm gear reducer 4 to rotate the internal gear ring 18. The angle between the connection block 14 and the fixed rod 1 can be adjusted for easy adjustment.

[0045] Example 2

[0046] refer to Figure 2 , Figures 4-6 Based on embodiment 1, the following improvements are made: a connecting ring 12 is provided on the fixed rod 1, and a distance scale line section 13 is provided on the fixed rod 1 at the end away from the turbine reducer 4. The bracket 2 is connected to the distance scale line section 13 through the connecting ring 12. The range of the distance scale line section 13 is 0-500mm. In this way, the position of the connecting ring 12 on the distance scale line section 13 can be adjusted according to the required distance to ensure that the distance is the optimal spray distance. The structure of the connecting ring 12 can refer to the multi-functional spray gun holder structure for coating machines disclosed in the applicant's earlier patent application with publication number CN 218637736U.

[0047] The end of the coupling 5 extending outside the coating machine is flush with the outer wall of the coating machine and is provided with a connecting groove 51. The rotating handle 6 is provided with a matching connecting protrusion 61 facing the connecting groove 51. When the connecting protrusion 61 is inserted into the connecting groove 51, the coupling 5 and the rotating handle 6 rotate synchronously. The connecting groove 51 can be polygonal, such as hexagonal, quadrilateral, or cross-shaped. The connecting protrusion 61 is adapted to the connecting groove 51. In this way, the rotating handle 6 can be detached, which is convenient to use and makes the whole thing more beautiful.

[0048] The rotating handle 6 includes a first rod 601 arranged in a straight line with the coupling 5, a second rod 602 arranged perpendicular to the first rod 601, and a third rod 603 arranged perpendicular to the second rod 602 and in a direction away from the spray gun 3. An operating sleeve 604 is provided on the third rod 603. The rotating handle 6 with this structure is conducive to the operator operating the spray gun 3 more precisely. The operating sleeve 604 is made of plastic or rubber, which has a better operating feel.

[0049] A method for using a coating machine with an intelligently adjustable spray gun includes the following steps:

[0050] S1. First, insert the rotating handle 6 into the coupling 5, and rotate the rotating handle 6 to drive the output end of the turbine reducer 4 to rotate. Then, start the third electromagnet ring 22 and the fourth electromagnet ring 23 so that they attract each other and fix the connecting block 14 on the output end of the turbine reducer 4. At this time, the rotation of the output end of the turbine reducer 4 can drive the connecting block 14 to rotate, and adjust the angle of the spray gun 3.

[0051] S2. When further adjustment is needed, activate the third electromagnet ring 22 and the fourth electromagnet ring 23 to fix the connecting block 14, and then drive the internal gear ring 18 to rotate. Through the gear 17 and the internal gear ring 18, drive the fixing rod 1 to rotate on the connecting block 14 to further adjust the angle of the spray gun 3.

[0052] S3. After adjustment, rotate the positioning piece 11 through the first positioning hole 91 and the second positioning hole 101 to fix the rotating handle 6.

[0053] S4. When it is necessary to remove the rotating handle 6, remove the positioning part 11 from the first positioning plate 9. At this time, the rotating handle 6 can be removed from the coupling 5.

[0054] However, as is well known to those skilled in the art, the working principle and wiring method of the third electromagnet ring 22 and the fourth electromagnet ring 23 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
