Abstract
Description
Technical Field
[0001] This utility model relates to the field of sugar coating machine technology, and in particular to a screw structure for fixing components of a sugar coating machine. Background Technology
[0002] Sugar coating machines are widely used in pharmaceutical, chemical, food, research institute, and hospital industries for sugar coating, polishing, and rolling tablets and pills. They can also be used by research units to trial-produce new drugs. Sugar-coated tablets, after coating and polishing, have a bright, glossy appearance. The complete, solidified coating formed by the crystallization of sugar on the surface prevents oxidation, deterioration, moisture absorption, or evaporation of the tablets. It also masks the unpleasant taste of the tablets, making them easier to identify and facilitating dissolution in the digestive system.
[0003] A sugar coating machine includes a frame, a sugar coating pot mounted on the frame, a geared motor, a fan, and other components on one side of the frame or sugar coating pot that enable the machine's functions. Existing geared motors consist of a worm gear, a worm shaft, and a positioning shaft bearing. The worm gear is a machined and inlaid combination of brass and iron, secured by 12 positioning screws on two sides. The positioning screw holes have threads running between the brass and iron. During operation, excessive load on the worm gear and worm shaft causes excessive torque in the brass threaded holes, leading to deformation and screw loosening. These screws then fall into the reducer cavity, damaging the worm gear and worm shaft if not addressed promptly, thus affecting the reducer's lifespan. Furthermore, the screws securing the fan blades are prone to loosening and falling into the sugar coating pot, impacting product quality. Utility Model Content
[0004] The purpose of this invention is to provide a screw structure for fixing components of a sugar coating machine, in order to solve the problem in the background art where fixing screws and positioning screws are prone to falling off, thereby affecting product quality and the service life of the geared motor.
[0005] To achieve the above objectives, this utility model provides a screw structure for fixing components of a sugar coating machine, including a sugar coating machine body. The sugar coating machine body includes a frame and a sugar coating pot mounted on the frame. A geared motor is also mounted on the frame. A fan is mounted on one side of the sugar coating pot. A heating device for heating air is connected to one side of the fan, and the fan is connected by fixing screws.
[0006] Preferably, the geared motor includes a positioning shaft, a worm gear is provided around the positioning shaft, and a worm is provided on the worm gear and connected thereto. The worm gear is composed of brass parts and iron parts machined and inlaid, and is fixed by a number of positioning screws.
[0007] Preferably, the positioning screw is threaded between the brass component and the iron component, and a hole is drilled 3cm outside the positioning screw on the brass component at a 30-degree angle to the worm gear and toward the positioning shaft, and fixed by threading with No. 8 screw thread.
[0008] Preferably, the hole extends 2 cm into the positioning shaft.
[0009] Preferably, a spring washer is provided on the fixing screw, and the spring washer is connected to the fixing screw by adhesive.
[0010] Therefore, the screw structure for fixing components of a sugar coating machine using the above-described structure has the following beneficial effects:
[0011] (1) By modifying the fixing screws, the problem of fixing screws falling off is solved, thereby ensuring product quality;
[0012] (2) By modifying the structure of the positioning screw, the positioning screw is less likely to fall off, reducing the number of maintenance times and extending the service life of the geared motor.
[0013] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] Example
[0022] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.
[0023] like Figure 1-Figure 4 As shown, a screw structure for fixing components of a sugar coating machine includes a sugar coating machine body. The sugar coating machine body adopts a common sugar coating machine on the market. This embodiment mainly solves the modification structure of the positioning screw 5 of the geared motor and the fixing screw 7 of the fan 6 on the sugar coating machine. Therefore, the specific structural components of the sugar coating machine are not described in detail in this embodiment, only the specific structure of the modification position is described. The sugar coating machine body includes a frame and a sugar coating pot set on the frame. A geared motor is also set on the frame. A fan 6 is set on one side of the sugar coating pot. A heating device for air heating is connected to one side of the fan 6, and the fan 6 is connected by fixing screw 7.
[0024] The geared motor includes a positioning shaft 1, with a worm gear 2 surrounding it. A worm is mounted on the worm gear 2 and connected to it. The worm gear 2 is machined and inlaid with brass components 3 and iron components, and is fixed by twelve positioning screws 5 on both sides. The positioning screws 5 are threaded between the brass components 3 and the iron components. A hole is drilled 3cm outside the positioning screw 5 on the brass component 3 at a 30-degree angle to the worm gear 2 towards the positioning shaft 1, and secured with No. 8 thread. The hole extends 2cm into the positioning shaft 1. This design effectively prevents the worm gear 2 and worm from being overloaded during operation, causing excessive torque in the threaded hole of the brass component 3, deformation of the threaded hole, and the positioning screws 5 from falling out and into the geared motor's cavity, thus affecting the motor's service life. The modified positioning screws 5 are less prone to falling out, reducing maintenance frequency and extending the geared motor's lifespan.
[0025] A spring washer 8 is provided on the fixing screw 7. The spring washer 8 is connected to the fixing screw 7 with glue, thereby solving the problem that the fixing screw 7 is easy to fall off and fall into the sugar coating pot, affecting the product quality.
[0026] Therefore, this utility model adopts a screw structure for fixing components of a sugar coating machine with the above-mentioned structure. By modifying the fixing screw, the problem of the fixing screw being easy to fall off is solved, thereby ensuring product quality; by modifying the positioning screw structure, the positioning screw is not easy to fall off, reducing its maintenance frequency and extending the service life of the geared motor.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
