Description

Technical Field

[0001] This application relates to the field of coating machine technology, and more particularly to a feed trolley for a coating machine that is easy to adjust. Background Technology

[0002] The high-efficiency coating machine is an efficient, energy-saving, safe, and clean electromechanical integrated device that can coat tablets, pills, candies, etc. with organic film, water-soluble film, and sustained-release or controlled-release coatings. The coating machine is suitable for the pharmaceutical, chemical, and food industries. By rotating the pot clockwise, the sugar-coated tablets roll, slide, rub, and grind inside the pot. Sugar coating powder is poured in by hand to ensure that the sugar coating powder is evenly distributed on all the tablets. The included electric heating blower has an air outlet pipe that extends into the sphere for heating. At the same time, the blower blows hot air into the inner layer of the pot to remove the surface moisture of the tablets, thus obtaining firm sugar-coated tablets.

[0003] Currently, the feeding of small and medium-sized coating machines is generally done manually and with the help of an auxiliary feeding pipe. During the feeding process, the auxiliary feeding pipe is prone to instability, which can lead to material spillage and waste of resources. At the same time, the operation is cumbersome and inconvenient, resulting in low feeding efficiency and affecting the production efficiency of the coating machine.

[0004] To address this, we designed an easily adjustable feeding trolley for coating machines. Summary of the Invention

[0005] This application provides an adjustable feeding cart for a coating machine, which allows for adjustment of the size of the feeding roll, making it easy to adapt the feeding end of the feeding roll to the size of the feeding port of coating machines of different specifications. At the same time, it eliminates the need for manual material lifting and feeding, thereby improving the feeding efficiency of the coating machine.

[0006] This application provides an easily adjustable feeding cart for a coating machine, comprising: a movable base, a fixed mounting cylinder on the movable base, a mounting cavity inside the fixed mounting cylinder, a feeding drum on the fixed mounting cylinder, one end of the feeding drum being rolled up and overlapped, and the other end having a feeding end with a semi-circular cross-section, a height adjustment mechanism inside the mounting cavity, a mounting plate at the end of the height adjustment mechanism away from the movable base, an angle adjustment mechanism on the mounting plate, and a size adjustment mechanism on the outer side of the feeding drum;

[0007] By moving the feeding end of the feeding cart to the feeding port of the coating machine, the output end of the electric telescopic rod is controlled by the control panel to push the fixed ring for angle adjustment. The rack, driven by the handwheel, first worm gear, first worm wheel, spur gear, and rack, pushes the lifting adjustment rod for height adjustment. When the feeding port does not match the feeding end of the feeding cart, the size of the feeding drum is adjusted by the adjustment mechanism to ensure the feeding end of the feeding drum matches the size of the coating machine's feeding port. The operation is simple and convenient. The adjusted feeding end is inserted into the coating machine, and the material is fed into the feeding drum by opening the hopper. The material enters the coating machine through the feeding end and is then coated by the coating machine.

[0008] The technical solutions described in this application embodiment have at least the following technical effects:

[0009] 1. This application, through the cooperation of a drive motor, a second worm gear, a second worm wheel, a rotating cylinder, and a fixed ring, enables multiple limit slide rods to drive multiple limit sliders and an arc-shaped stop plate to simultaneously move closer to or further away from the center of the rotating cylinder, thereby adjusting the size of the feed roll. This facilitates the adjustment of the feed end of the feed roll to match the size of the coating machine's feed inlet, making the operation simple and convenient.

[0010] 2. This application uses a control panel to control the output end of the electric telescopic rod to push the fixed ring to adjust the angle, so that the material can enter the coating machine through the feeding end. This eliminates the need for manual material lifting and feeding, saving time and reducing production and operating costs. The universal locking casters facilitate the movement of the feeding cart and can be adjusted according to the size, improving flexibility.

[0011] 3. This application utilizes the cooperation of a handwheel, a first worm gear, a first worm wheel, a spur gear, and a rack to enable the rack to push the lifting adjustment rod to adjust the height to a suitable level. Furthermore, the self-locking characteristics of the worm wheel and worm gear result in a reasonable and effective structure.

[0012] In this embodiment, the size adjustment mechanism includes:

[0013] The working part includes a fixed ring, a rotating cylinder, a second worm gear, and multiple limiting sliders. The inner wall of the fixed ring is tightly fitted against the outer wall of the feed drum. The rotating cylinder is rotatably connected to the fixed ring, and the second worm gear is coaxially fixedly connected to the rotating cylinder.

[0014] The drive unit includes a drive motor and a second worm gear. A fixed plate is provided on the fixed ring. The drive motor is fixedly mounted on the fixed plate. The output end of the drive motor is coaxially and fixedly connected to the second worm gear, and the second worm gear meshes with a second worm wheel for transmission.

[0015] By adopting the above technical solution, when the feed inlet of the coating machine does not match the feed end of the feeding trolley, multiple limit slides in the size adjustment mechanism drive multiple limit sliders and arc-shaped abutments to move closer to or further away from the center of the rotating drum, thereby adjusting the size of the feed roll. This makes it easy to adjust the feed end of the feed roll to match the size of the feed inlet of the coating machine. The operation is simple and convenient. The adjusted feed end is inserted into the coating machine, and the material is fed into the feed roll by opening the hopper. The material entering the feed roll enters the coating machine through the feed end, and finally, the coating machine performs the coating operation.

[0016] In this embodiment, a rotating groove is provided at one end of the fixed ring near the rotating cylinder, and the rotating cylinder is coaxially disposed in the rotating groove. An installation hole is provided at one end of the rotating cylinder away from the fixed ring. Multiple limiting grooves are provided on the side wall of the rotating cylinder outside the installation hole. A limiting slide rod is provided on the limiting slider, and the limiting slide rod is disposed in the limiting groove. A limiting block is provided at one end of the limiting slide rod away from the limiting slider, and an arc-shaped abutment is provided at one end of the limiting slider away from the rotating cylinder.

[0017] By adopting the above technical solution, when multiple limit slide rods in the size adjustment mechanism drive multiple limit sliders and arc-shaped abutment to move closer to or further away from the center of the rotating drum, the size of the feed roll can be adjusted, making it easier to adjust the feed end of the feed roll to match the size of the coating machine feed inlet.

[0018] In this embodiment, the width of the limiting block is greater than the width of the limiting groove.

[0019] In this embodiment, the sidewalls of the multiple arc-shaped abutments are in close contact with the feed drum, and the fixed ring is provided with a frustum at one end near the rotating drum. A limiting guide groove is provided on the frustum to facilitate the limiting guide of the limiting slider.

[0020] In this embodiment, the height adjustment mechanism includes:

[0021] A lifting adjustment rod is coaxially disposed inside a fixed mounting cylinder. One end of the lifting adjustment rod disposed inside the fixed mounting cylinder is coaxially provided with a sliding plate. The side wall of the sliding plate is in close contact with the inner wall of the mounting cavity of the fixed mounting cylinder.

[0022] The first worm gear and the handwheel, one end of the first worm gear is rotatably connected to the inner wall of the mounting cavity, and the other end passes through the fixed mounting cylinder and is coaxially fixedly connected to the handwheel;

[0023] The first worm gear, spur gear, and rack are mounted in the mounting cavity, and a rotating shaft is rotatably connected therein. The first worm gear and spur gear are both fixedly connected to the rotating shaft on the same axis. The rack is vertically arranged in the mounting cavity and fixedly connected to the slide plate. The spur gear meshes with the rack for transmission.

[0024] By adopting the above technical solution, rotating the handwheel causes the first worm and the first worm wheel to mesh and transmit power. Since the spur gear and the first worm wheel are coaxially connected by a rotating shaft, when the first worm wheel rotates, it drives the spur gear to rotate, which in turn causes the spur gear to mesh and transmit power with the rack. Finally, the rack pushes the lifting adjustment rod to adjust the height to a suitable height. Moreover, due to the self-locking characteristics of the worm wheel and the worm, the structure is reasonable and effective.

[0025] In this embodiment, the fixed mounting cylinder has an output hole coaxially formed at the end away from the movable base, and the outer wall of the lifting adjustment rod contacts the inner wall of the output hole.

[0026] In this embodiment, the angle adjustment mechanism includes:

[0027] A set of mounting shafts is fixedly mounted on a mounting plate, and the feed drum is arranged between the set of mounting shafts.

[0028] A set of electric telescopic rods, each set of electric telescopic rods is respectively mounted on a set of mounting shafts, one end of each electric telescopic rod is rotatably connected to the mounting shaft, and the other end is rotatably connected to a fixing ring;

[0029] By adopting the above technical solution, the output end of the electric telescopic rod is controlled by the control board to push the fixed ring to adjust the angle, so that the material can enter the interior of the coating machine through the feeding end. There is no need for personnel to manually lift and feed the material, saving time and improving the working efficiency of the coating machine.

[0030] In this embodiment, the bottom of the movable base is provided with multiple omnidirectional locking wheels for easy movement. Attached Figure Description

[0052] The high-efficiency coating machine is a highly efficient, energy-saving, safe, and clean electromechanical integrated device capable of organic film coating, water-soluble film coating, and sustained-release / controlled-release coating of tablets, pills, and candies. It is suitable for the pharmaceutical, chemical, and food industries. The machine works by rotating the pot clockwise, causing the sugar-coated tablets to tumble, slide, rub, and grind within the pot. Sugar powder is then manually poured in, ensuring even distribution across all the tablets. An included electric blower with an outlet pipe extending into the sphere provides heating, while simultaneously blowing hot air into the inner layer of the pot to remove surface moisture from the tablets, resulting in firm, sugar-coated tablets.

[0053] In related technologies, the feeding of small and medium-sized coating machines is generally done manually. During the feeding process, material spillage is likely to occur, resulting in resource waste and low feeding efficiency, which is not conducive to improving the production efficiency of the coating machine.

[0054] Based on this, in order to improve the problem of low feeding efficiency and easy material spillage during the feeding process in related technologies, which leads to resource waste, the embodiments of this application provide the following solutions.

[0055] Please see Figures 1 to 7 This application provides an easily adjustable feeding cart for a coating machine, including a movable base 1, a fixed mounting cylinder 2 on the movable base 1, an mounting cavity inside the fixed mounting cylinder 2, and a feeding drum 4 on the fixed mounting cylinder 2. One end of the feeding drum 4 is arranged in a coiled and overlapping manner, and the other end is provided with a feeding end 41 with a semi-circular cross section.

[0056] The effect of this setting is that when the feed inlet 51 of the coating machine 5 does not match the feed end 41 of the feeding cart, multiple limit slides 452 in the size adjustment mechanism drive multiple limit sliders 45 and arc-shaped abutment 451 to move closer to or further away from the center of the rotating drum 43, thereby adjusting the size of the feed drum 4. This makes it easy to adjust the feed end 41 of the feed drum 4 to match the size of the feed inlet 51 of the coating machine 5. The operation is simple and convenient. The adjusted feed end 41 is inserted into the coating machine 5, and the material is fed into the feed drum 4 by opening the hopper 52. The material entering the feed drum 4 enters the coating machine 5 through the feed end 41, and finally the coating machine 5 performs the coating operation.

[0057] Please see Figures 1 to 5The feed drum 4 is provided with a size adjustment mechanism on its outer side. The size adjustment mechanism includes a working part and a driving part. The working part includes a fixed ring 42, a rotating drum 43, a second worm gear 44 and multiple limit sliders 45. The inner wall of the fixed ring 42 is tightly fitted to the outer wall of the feed drum 4. The rotating drum 43 is rotatably connected to the fixed ring 42. The second worm gear 44 is coaxially fixedly connected to the rotating drum 43. The driving part includes a drive motor 46 and a second worm 47. A fixed plate 48 is provided on the fixed ring 42. The drive motor 46 is fixedly mounted on the fixed plate 48. The output end of the drive motor 46 is coaxially fixedly connected to the second worm 47, and the second worm 47 meshes with the second worm gear 44 for transmission.

[0058] The effect of this setting is that the output end of the drive motor 46 drives the second worm 47 to mesh with the second worm wheel 44, so that the second worm wheel 44 drives the rotating drum 43 to rotate, and so that multiple limit slide rods 452 drive multiple limit sliders 45 and arc-shaped abutment 451 to move closer to or away from the center of the rotating drum 43 at the same time, thereby adjusting the size of the feed drum 4.

[0059] Please see Figures 3 to 5 A rotating groove 421 is provided at one end of the fixed ring 42 near the rotating cylinder 43. The rotating cylinder 43 is coaxially disposed in the rotating groove 421. An installation hole is provided at the end of the rotating cylinder 43 away from the fixed ring 42. Multiple limiting grooves 441 are provided on the side wall of the rotating cylinder 43 outside the installation hole. A limiting slide rod 452 is provided on the limiting slider 45. The limiting slide rod 452 is disposed in the limiting groove 441. A limiting block 453 is provided at the end of the limiting slide rod 452 away from the limiting slider 45. An arc-shaped abutment 451 is provided at the end of the limiting slider 45 away from the rotating cylinder 43. The width of the limiting block 453 is greater than the width of the limiting groove 441.

[0060] The effect of this setting is that, since the rotating drum 43 has multiple arc-shaped limiting grooves 441, under the rotation of the second worm gear 44, the multiple limiting grooves 441 simultaneously squeeze the multiple limiting slide rods 452, so that the multiple limiting slide rods 452 drive the multiple limiting sliders 45 and the arc-shaped abutment 451 to move closer to or further away from the center of the rotating drum 43 at the same time, thereby realizing the adjustment of the size of the feed drum 4.

[0061] Please see Figures 3 to 5 The side walls of multiple arc-shaped abutments 451 are in close contact with the feed drum 4. The fixed ring 42 is provided with a frustum at one end near the rotating drum 43. A limiting guide groove is provided on the frustum to facilitate the limiting guide of the limiting slider 45.

[0062] This design facilitates the adjustment of the size of the feed drum 4 by simultaneously moving multiple arc-shaped abutments 451 toward or away from the center of the rotating drum 43. At the same time, the limiting guide groove on the platform serves to limit and guide the limiting slider 45, ensuring that when the second worm gear 44 drives the rotating drum 43 to rotate, the limiting slider 45 cooperates with the limiting guide groove, and the limiting slide rod 452 cooperates with the limiting groove 441, so that the arc-shaped abutments 451 simultaneously move toward or away from the center of the rotating drum 43.

[0063] Please see Figure 1 and Figure 7 The height adjustment mechanism includes a lifting adjustment rod 21, which is coaxially arranged inside the fixed mounting cylinder 2. One end of the lifting adjustment rod 21, which is located inside the fixed mounting cylinder 2, is coaxially provided with a sliding plate. The side wall of the sliding plate is in close contact with the inner wall of the mounting cavity of the fixed mounting cylinder 2.

[0064] The height adjustment mechanism also includes a first worm gear 22 and a handwheel 23. One end of the first worm gear 22 is rotatably connected to the inner wall of the mounting cavity, and the other end passes through the fixed mounting cylinder 2 and is coaxially fixedly connected to the handwheel 23.

[0065] The height adjustment mechanism also includes a first worm gear 24, a spur gear 25 and a rack 26. A rotating shaft is rotatably connected inside the mounting cavity. The first worm gear 24 and the spur gear 25 are both coaxially and fixedly connected to the rotating shaft. The rack 26 is vertically arranged inside the mounting cavity and is fixedly connected to the slide plate. The spur gear 25 meshes with the rack 26 for transmission.

[0066] The effect of this setup is that by rotating the handwheel 23, the first worm 22 and the first worm wheel 24 engage in transmission. Since the spur gear 25 and the first worm wheel 24 are coaxially connected by a rotating shaft, when the first worm wheel 24 rotates, it drives the spur gear 25 to rotate, which in turn causes the spur gear 25 to engage in transmission with the rack 26. Ultimately, the rack 26 pushes the lifting adjustment rod 21 to adjust the height to a suitable level. Furthermore, due to the self-locking characteristics of the worm wheel and worm, the structure is reasonable and effective.

[0067] Please see Figure 1 and Figure 7 The fixed mounting cylinder 2 has an output hole coaxially opened at one end away from the movable base 1, and the outer wall of the lifting adjustment rod 21 contacts the inner wall of the output hole;

[0068] This design allows for the output hole to be coaxially opened at the end of the fixed mounting cylinder 2 away from the movable base 1, so that when the rack 26 pushes the lifting adjustment rod 21 to move upward, it can play a limiting and guiding role on the lifting adjustment rod 21.

[0069] Please see Figure 1 and Figure 2The installation cavity is equipped with a height adjustment mechanism. The end of the height adjustment mechanism away from the movable base 1 is equipped with an installation plate 3. The installation plate 3 is equipped with an angle adjustment mechanism. The angle adjustment mechanism includes a set of installation shafts. The set of installation shafts is fixedly installed on the installation plate 3. The feed drum 4 is arranged between the set of installation shafts.

[0070] The angle adjustment mechanism also includes a set of electric telescopic rods 31, which are respectively mounted on a set of mounting shafts. One end of the electric telescopic rod 31 is rotatably connected to the mounting shaft, and the other end is rotatably connected to the fixing ring 42.

[0071] The effect of this setup is that the output end of the electric telescopic rod 31, controlled by the control panel, pushes the fixed ring 42 to adjust the angle, allowing the material to enter the interior of the coating machine 5 through the feed end 41. This eliminates the need for manual material lifting and feeding, saving time and improving the working efficiency of the coating machine 5.

[0072] Please see Figure 1 and Figure 2 The bottom of the movable base 1 is equipped with multiple universal locking wheels 11 for easy movement;

[0073] This design allows for easy movement of the feeding cart via omnidirectional locking casters, which can be adjusted automatically according to size, thus improving flexibility.

[0074] As can be seen from the above, the working principle of this application is as follows:

[0075] By moving the feed end 41 of the feeding car to the feed port 51 of the coating machine 5, and rotating the handwheel 23, the first worm 22 and the first worm wheel 24 mesh and drive. When the first worm wheel 24 rotates, it drives the spur gear 25 to rotate, which in turn causes the spur gear 25 to mesh and drive the rack 26. Finally, the rack 26 pushes the lifting adjustment rod 21 to adjust the height to a suitable height.

[0076] At the same time, the output end of the electric telescopic rod 31 is controlled by the control board to push the fixed ring 42 to adjust the angle, so that the material can enter the inside of the coating machine 5 through the feeding end 41. There is no need for personnel to manually lift and feed the material, saving time and reducing production and operating costs.

[0077] When the feed inlet 51 of the coating machine 5 does not match the feed end 41 of the feeding cart, the output end of the drive motor 46 drives the second worm 47 to mesh with the second worm wheel 44. Under the rotation of the second worm wheel 44, multiple limiting grooves 441 simultaneously squeeze multiple limiting slide bars 452, causing multiple limiting slide bars 452 to drive multiple limiting sliders 45 and arc-shaped abutment plates 451 to move closer to or further away from the center of the rotating drum 43. The adjusted feed end 41 is extended into the coating machine 5, and the material is discharged into the feed roll 4 by opening the hopper 52. The material entering the feed roll 4 enters the coating machine 5 through the feed end 41, and finally the coating machine 5 performs the coating operation.

[0078] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.

[0079] While this application has been described with reference to several specific embodiments, it should be understood that this application is not limited to the disclosed specific embodiments. This application is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
