[0002] A film coating machine, also known as a thin film coating machine, is a device used to coat drugs or foods with a thin film. The basic working principle of the thin film coating machine is to put pills or tablets into the coating chamber, and through rotation, they are subjected to friction and dissolution, and the coating solution is covered on the surface of the drug, and then through methods such as heating and air cooling, it is solidified on the surface to form a hard shell.

[0003] Therefore, after the tablets are placed in the inner chamber of the film coating machine, it is necessary to close the door panel of the machine body in time to avoid the sterile environment of the machine body chamber being contaminated by external sundries. However, after long-term labor, affected by their own physical fatigue, the staff are prone to make misoperations, resulting in starting the film coating machine to carry out film coating before closing the door panel, damaging the sterile environment of the machine body chamber and affecting the overall film coating effect.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , a film coating machine, comprising: the main body 1 of the film coating machine, a protective door panel 2 is arranged on the main body 1 of the film coating machine, and an operation button 4 for starting or closing the main body 1 of the film coating machine is arranged on the surface of the main body 1 of the film coating machine. A limiting component 5 and a driving component 6 are also arranged on the main body 1 of the film coating machine; a connecting seat 3 for connecting a film coating raw material feeder is arranged on the top surface of the main body 1 of the film coating machine.

[0024] The limit component 5 includes a clamping strip 51, a slider 52, a lead screw 53, a pulley set 54, a transmission shaft 55, a first reversing gear 56, a second reversing gear 57 and an anti-slip pad 58; the clamping strip 51 is fixedly installed on the slider 52, the slider 52 is slidably arranged on the film coating machine body 1 and is threadedly connected to the lead screw 53, the lead screw 53 is rotatably arranged on the film coating machine body 1, the pulley set 54 is movably arranged inside the film coating machine body 1, the transmission shaft 55 is rotatably arranged inside the film coating machine body 1, the first reversing gear 56 is fixedly installed on the transmission shaft 55 and meshes with the second reversing gear 57, there are two lead screws 53 in total, one of the lead screws 53 is fixedly connected to the second reversing gear 57, the other lead screw 53 is fixedly connected to the second bevel gear 66, and at the same time, the second reversing gear 57 and the first reversing gear 56 have the same size, so that the two lead screws 53 can rotate in opposite directions and at the same speed, and then cooperate with the clamping strip 51 to clamp the operation button 4, achieving the effect that the film coating machine body 1 cannot be started when the protective door panel 2 is opened. The clamping strip 51 contacts the operation button 4 to form a contact surface, and the contact surface is arc-shaped. The anti-slip pad 58 is arranged on the contact surface, and anti-slip lines are arranged on the anti-slip pad 58 to ensure the clamping effect of the clamping strip 51, thereby restricting the movement of the operation button 4 and achieving the purpose of avoiding the negative impact on the whole process caused by the staff's misoperation. The slider 52 is L-shaped and is located below the operation button 4, which can avoid adding structures affecting the use of the operation button 4, thereby ensuring the rationality of the overall structural design.

[0025] The driving component 6 includes a driving rack 61, a transmission gear 62, a connecting block 63, a return spring 64, a first bevel gear 65 and a second bevel gear 66. The driving rack 61 is slidably arranged inside the film coating machine body 1, the transmission gear 62 is rotatably arranged inside the film coating machine body 1 and meshes with the driving rack 61, the connecting block 63 is fixedly installed on the driving rack 61, both ends of the return spring 64 are fixedly connected to the connecting block 63 and the film coating machine body 1 respectively, the first bevel gear 65 is fixedly installed on the gear shaft of the transmission gear 62, and the first bevel gear 65 also meshes with the second bevel gear 66. A chamfer is arranged at the end of the driving rack 61 close to the protective door panel 2, which can ensure that the driving rack 61 slides on the film coating machine body 1 under the combined action of the return spring 64 as the position of the protective door panel 2 changes, so as to achieve the purpose of pre-establishing such structures.

[0026] Working principle: after opening the protective door panel 2, a connecting block 63 is fixed on the driving rack 61 which is slidably connected inside the film coating machine body 1. The connecting block 63 is further connected to the film coating machine body 1 through a return spring 64. Therefore, under the action of the return spring 64, the driving rack 61 slides toward the outside of the film coating machine body 1. During the sliding process of the driving rack 61, the transmission gear 62 will be driven to rotate synchronously. The first bevel gear 65 fixed on the gear shaft of the transmission gear 62 is meshed with the second bevel gear 66, and the second bevel gear 66 is fixed on one of the screw rods 53. On the two screw rods 53, the screw rod 53 on which the second bevel gear 66 is fixed is connected to the transmission shaft 55 through a pulley set 54. The transmission shaft 55 is fixed with a first reversing gear 56 which is meshed with a second reversing gear 57, and the second reversing gear 57 is fixed on another screw rod 53. Therefore, when the transmission gear 62 rotates, one of the screw rods is driven through the first bevel gear 65 and the second bevel gear 66. After 53 rotates forward, the other screw rod 53 will rotate in the opposite direction. The two screw rods 53 are threadedly connected to the slider 52, and the slider 52 is in a sliding connection with the film coating machine body 1. Therefore, as the two screw rods 53 rotate in a positive and negative direction, the two sliders 52 will perform mirror sliding movements in opposite directions. At this time, the clamping strip 51 fixed on the slider 52 will move toward the operating button 4 on the film coating machine body 1 until the anti-slip pad 58 on the clamping strip 51 contacts the operating button 4, and then the two clamping strips 51 cooperate with each other to clamp the operating button 4 to limit the opening of the protective door panel 2. After closing the protective door panel 2, the driving rack 61 is squeezed and slides back, and the transmission gear 62 will rotate in the opposite direction, thereby prompting the slider 52 and the clamping strip 51 to slide in the direction away from the operating button 4, releasing the restriction on the operating button 4. At this time, the staff can start the film coating machine body 1 through the operating button 4 for coating.

[0027] Although the embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
