[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-8 This utility model provides a technical solution: a sugar coating removal device, including a working plate 1, a plurality of support columns 2 fixed at the bottom end of the working plate 1, a placement groove provided at the middle position of the top surface of the working plate 1, a tablet 5 placed inside the groove on the top surface of the working plate 1, and a clamping mechanism 6 for clamping the tablet 5 provided near the rear end of the top surface of the working plate 1, and further including:

[0032] The peeling mechanism 7, located on the top surface of the work plate 1, is used to peel off the sugar coating on the surface of the tablet 5. The peeling mechanism 7 includes a frame 71 fixed to the top surface of the work plate 1 and positioned to the left and right; two rotating columns 72 rotatably connected to the two vertical ends of the frame 71; a screw 73 coaxially fixed between the two rotating columns 72; a rotating rod 712 coaxially fixed to the surface of one of the rotating columns 72 away from the screw 73; two gears 713 located above the work plate 1 and used to drive the rotating rod 712 to rotate; a motor 714 mounted on the outer wall of one of the vertical ends of the frame 71 and used to drive the two gears 713 to rotate; a connecting plate 74 slidably connected to the bottom surface of the horizontal end of the frame 71 and threadedly connected to the screw 73; and a mounting plate 74 fixed to the bottom surface of the connecting plate 74. 6. An electric cylinder 77 is mounted on the bottom surface of the mounting plate 76; a lifting plate 78 is located below the electric cylinder 77 and fixed to the piston rod of the electric cylinder 77 by a gasket 79; a scraper 710 is mounted on the bottom surface of the lifting plate 78 for peeling off the sugar coating on the surface of the tablet 5; and two gears 713 mesh with each other. The tablet 5 can be placed by setting a working plate 1, several support columns 2, and a placement groove on the top surface of the working plate 1. The tablet 5 can be clamped and fixed by setting a clamping mechanism 6. The sugar coating on the surface of the tablet 5 can be scraped off by setting a peeling mechanism 7. At the same time, the height of the scraper 710 can be adjusted according to the thickness of the tablet 5, thereby making the entire device more practical. There is no need for manual peeling of the sugar coating on the surface of the tablet 5, saving time and effort.

[0033] In this embodiment, a guide groove is provided on the bottom surface of the horizontal plate end of the frame 71, and a guide block 75 is fixed on the top surface of the connecting plate 74 and slidably connected to the guide groove on the bottom surface of the horizontal plate end of the frame 71. This can guide the movement of the connecting plate 74, and thus indirectly guide the movement of the scraper 710.

[0034] In addition, the stripping mechanism 7 also includes a rotating shaft 715 coaxially connected to the output shaft of the motor 714, and two gears 713 are coaxially fixed on the outer circumference of the rotating shaft 715 and the rotating rod 712, respectively, which can smoothly drive the two gears 713 to rotate, and thus smoothly drive the screw 73 to rotate.

[0035] Furthermore, a support plate 3 is fixed to the bottom of the support column 2, and an anti-slip plate 4 that matches the shape of the support plate 3 is fixed to the bottom of the support plate 3. The thickness of the anti-slip plate 4 is 1-3cm, preferably 2cm in this paper, which can increase the contact area and friction between the entire device and the ground, thereby making the entire device more stable during operation.

[0036] Furthermore, the clamping mechanism 6 includes two fixed plates 61 fixed on the top surface of the working plate 1 and symmetrical to each other, two rotating rollers 62 rotatably connected to the fixed plate 61 on the same side, a bidirectional lead screw 63 coaxially fixed between the two rotating rollers 62, two moving blocks 64 threadedly connected to the bidirectional lead screw 63 and symmetrical to each other, and two clamping plates 65 fixed on the front surface of the moving blocks 64 on the same side. The moving blocks 64 are slidably connected to the top surface of the working plate 1. Protective plates 66 are fixed on the opposite sides of the two clamping plates 65, and the side surface of the protective plate 66 away from the clamping plate 65 on the same side is tightly fitted with the outer wall of the tablet 5 on the same side. Through the design of the clamping mechanism 6, the tablet 5 can be clamped and fixed.

[0037] Specifically, the longitudinal section shape of the guide groove on the bottom surface of the horizontal plate of the frame 71 is I-shaped, and the shape of the guide block 75 is I-shaped to match the shape of the guide groove on the bottom surface of the horizontal plate of the frame 71. This makes the connection between the guide block 75 and the guide groove on the bottom surface of the horizontal plate of the frame 71 tighter, thereby indirectly making the scraper 710 more stable during movement.

[0038] It is worth noting that the stripping mechanism 7 also includes a protective box 716 fixed to the surface of one of the vertical plates of the frame 71 away from the screw 73, a protective cylinder 711 fixed to the bottom surface of the mounting plate 76, a motor 714 located inside the protective box 716, a rotating shaft 715 penetrating the outer wall of the protective box 716 away from the screw 73, a cylinder body of an electric cylinder 77 located inside the protective cylinder 711, and a piston rod of the protective cylinder 711 penetrating the bottom surface of the protective cylinder 711, which can protect the electric cylinder 77 and the motor 714, thereby extending the service life of the electric cylinder 77 and the motor 714.

[0039] It is worth noting that the top surface of the working plate 1 is provided with a sliding groove, and the bottom surface of the moving block 64 is fixed with a slider 67 that is slidably connected to the sliding groove on the top surface of the working plate 1. This can guide the movement of the moving block 64, and thus indirectly guide the movement of the two clamping plates 65 and the two protective plates 66.

[0040] It is worth emphasizing that the clamping mechanism 6 also includes a connecting column 68 coaxially fixed to the surface of one of the rollers 62 away from the bidirectional lead screw 63, and a turntable 69 coaxially fixed to the surface of the connecting column 68 away from the bidirectional lead screw 63. A pusher 610 is fixed to the surface of the turntable 69 away from the connecting column 68, which facilitates driving one of the rollers 62 to rotate, thereby smoothly driving the bidirectional lead screw 63 to rotate.

[0041] Finally, it should be noted that the electric cylinder 77, motor 714 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0042] In this embodiment, when it is necessary to remove the sugar coating from the surface of the tablet 5, the tablet 5 is first placed in the middle of the placement groove on the top surface of the working plate 1. Then, the turntable 69 is turned by the lever 610. The rotation of the turntable 69 drives the connecting column 68, which is fixed coaxially with it, to rotate. The rotation of the connecting column 68 drives the rotating roller 62, which is fixed coaxially with it, to rotate. The rotation of the rotating roller 62 drives the bidirectional screw 63, which is fixed coaxially with it, to rotate. The rotation of the bidirectional screw 63 drives the two moving blocks 64, which are threadedly connected to it, to move closer to each other. The moving blocks 64 move under the guidance of the slider 67 on the same side and the sliding groove on the top surface of the working plate 1. The two moving blocks 64 move closer to each other, thereby driving the two clamping plates 65 and the two protective plates 66 to move closer to each other. When the surface of the protective plate 66 away from the clamping plate 65 on the same side is tightly attached to the outer wall of the tablet 5 on the same side, the lever 610 is stopped.

[0043] Next, the electric cylinder 77 is started via an external PLC. The piston rod of the electric cylinder 77 moves, causing the lifting plate 78, which is fixed to it via a shim 79, to move downwards. The movement of the lifting plate 78, in turn, causes the scraper 710, which is fixed to it, to move downwards. When the scraper 710 moves to the appropriate height position, the electric cylinder 77 is shut off via the external PLC. Subsequently, the external PLC starts and controls the output shaft of the motor 714 to rotate alternately in both directions. The rotation of the output shaft of the motor 714 causes the rotating shaft 715, which is coaxially connected to it, to rotate. The rotation of the rotating shaft 715 causes the gear 713, which is coaxially fixed to it, to rotate. The rotation of this gear 713 causes another gear 713, which meshes with it, to rotate. The rotation of this other gear 713 causes the rotating rod 712, which is coaxially fixed to it, to rotate. The rotation of rod 712 drives the rotation of the same-side rotating column 72, which is fixed coaxially with it. The rotation of rotating column 72 drives the rotation of screw 73, which is fixed coaxially with it. Because the output shaft of motor 714 rotates alternately in both directions, it indirectly drives screw 73 to rotate alternately in both directions. The alternating rotation of screw 73 drives connecting plate 74, which is threaded to it, to perform linear reciprocating motion in the left and right direction. Connecting plate 74 moves under the guidance of guide block 75 and guide groove on bottom surface of horizontal plate of frame 71. The movement of connecting plate 74 indirectly drives scraper 710 to perform linear reciprocating motion in the left and right direction. During the linear reciprocating motion of scraper 710 in the left and right direction, the sugar coating on the top surface of tablet 5 can be removed; similarly, the sugar coating on the bottom surface of tablet 5 can also be removed.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
