Description

Technical Field

[0001] The utility model belongs to the technical field of preparation machinery, and in particular relates to a leak-proof feeding box for tablet pressing. Background Art

[0002] In the prior art, the production process of tablets includes steps such as mixing raw materials, adding materials, and pressing into tablets. Traditional tablet feeding equipment has many shortcomings, such as low feeding efficiency, easy loss of raw materials during the feeding process, and uneven feeding, which directly affect the quality and production efficiency of tablets. Especially during the feeding and pressing process, the loss of raw materials not only causes a waste of raw materials, but also makes the dosage of the final prepared tablets inaccurate, and in severe cases even affects the efficacy and safety of the tablets.

[0003] During the feeding stage, traditional feeding equipment usually adopts a simple dropping method, that is, the raw materials fall directly from the storage hopper into the compression mold of the tablet press. This method lacks an effective control mechanism and cannot guarantee the accuracy and uniformity of the feeding process. In addition, due to the poor sealing performance of the feeding system, the raw materials are prone to leak from the interface during the transmission process, resulting in raw material loss on the production line and pollution of the working environment. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a leak-proof feeding box for tablet pressing, which can effectively prevent the leakage of raw materials, ensure the accuracy and uniformity of feeding, and thus improve the efficiency and quality of tablet production.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A material storage mechanism is provided at one end of the bracket, an output end of the material storage mechanism is connected to a feeding pipeline, a pressure component is movably connected to the feeding pipeline, and the pressure component is used to press out the raw materials in the feeding pipeline.

[0008] Furthermore, the material storage mechanism includes a storage hopper, the bottom of the storage hopper is laterally connected to a conveying pipe, one end of the conveying pipe is connected to a second motor, the output end of the second motor is connected to an auger, and the auger is arranged in the conveying pipe.

[0009] Furthermore, the feeding pipeline includes a main pipeline, one end of which is connected to the conveying pipe, and the top of the main pipeline is connected to temporary bins at equal intervals along its length, and the bottom of the main pipeline is fixedly connected to a material nozzle corresponding to the temporary bin, and a discharge hole is opened through the bottom of the material nozzle.

[0010] Furthermore, the pressure assembly includes a pressure plate, the bottom of which is plugged with a lower pressure rod corresponding to the temporary bin, the bottom of which is connected with a piston, and the piston is inserted into the temporary bin;

[0011] The lower pressure rod is sleeved with a spring and a compartment cover;

[0012] The bin cover is clamped on the top of the temporary bin, and the spring is located above the bin cover.

[0013] Furthermore, a socket is fixedly connected to the bottom of the pressure plate, and the socket is engaged with the top opening end of the temporary bin.

[0014] Furthermore, an eccentric wheel is connected to the output end of the first motor, and the eccentric wheel is in contact with the upper end surface of the pressure plate.

[0015] Furthermore, the inner opposite surface of the bracket is fixedly connected with a guide strip, and the sealing plate is inserted into the guide strip;

[0016] The outer sides of the bottoms of both ends of the bracket are fixedly connected with fixing plates.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By introducing a precisely designed material storage mechanism and conveying system, including a storage hopper, a conveying pipe, and an auger, the continuous and uniform supply of raw materials can be ensured, and the raw materials can be accurately conveyed to the tableting position through the rotation drive of the auger. This not only solves the problem of discontinuous raw material supply, but also effectively avoids the loss of raw materials during the transmission process through the precise control of the auger, thereby reducing raw material waste and improving production efficiency.

[0019] The utility model can accurately control the position of the sealing plate during the feeding and pressing process by setting up a cooperative working mechanism between the sealing plate and the cylinder, so as to achieve effective sealing of the discharge hole at the bottom of the nozzle. This design prevents the leakage of raw materials during the feeding process, ensures the accuracy of feeding and the complete utilization of raw materials. Especially in the pressing stage, the discharge hole is released by the movement of the sealing plate, and the action of the lower pressing rod and the piston is combined to achieve accurate extrusion and injection of the tablet raw materials, further ensuring the accuracy and uniformity of the dosage of the tablets.

[0020] The design of the pressure component optimizes the tablet pressing process. The eccentric wheel and the pressing plate are used together to convert the motor's rotary motion into a vertical pressing motion, achieving uniform pressing of the raw materials. Combined with the spring reset function and the design of the compartment cover, it not only ensures that the pressure component can quickly and accurately return to its original position after each pressing, preparing for the next feeding and pressing, but also further improves the continuity and efficiency of production.

[0036] A storage mechanism 4 is provided at one end of the bracket 1, and a feeding pipe 5 is connected to the output end of the storage mechanism 4; a pressure component 6 is movably connected to the feeding pipe 5, and the pressure component 6 is used to press out the raw materials in the feeding pipe 5 evenly and continuously by precisely controlling the pressure, thereby improving the uniformity of feeding and the quality of pressed tablets.

[0037] See also Figure 5 The storage mechanism 4 includes a storage hopper 41, which is used to store the tablet raw materials to be processed; a conveying pipe 42 is laterally connected to the bottom of the storage hopper 41, one end of the conveying pipe 42 is connected to a second motor 43, and an auger 44 is connected to the output end of the second motor 43. The auger 44 is arranged in the conveying pipe 42, and the raw materials are evenly conveyed to the main pipeline 51 through the rotation of the auger 44, ensuring the continuous supply of raw materials and no leakage during the conveying process.

[0038] See also Figure 4 The feeding pipeline 5 includes a main pipeline 51, one end of which is connected to the conveying pipe 42, ensuring the smooth transportation of the raw materials; and the top of the main pipeline 51 is connected with temporary bins 52 at equal intervals along its length direction, and these temporary bins 52 are used to temporarily store the raw materials transported from the main pipeline 51 so as to be evenly distributed to each tableting position; and the bottom of the main pipeline 51 is fixedly connected with a nozzle 53 corresponding to the temporary bin 52, and a discharge hole 531 is opened through the bottom of the nozzle 53. The design of the discharge hole 531 allows the raw materials to be accurately injected into the tableting chamber when the pressing plate 61 is pressed down, and is sealed by the sealing plate 3 during the feeding stage, effectively preventing the loss of raw materials.

[0039] See also Figure 5-6The pressure assembly 6 includes a pressing plate 61, a lower pressing rod 62 corresponding to the temporary bin 52 is inserted at the bottom of the pressing plate 61, a piston 63 is connected to the bottom of the lower pressing rod 62, and the piston 63 is inserted into the temporary bin 52; a spring 64 and a bin cover 65 are sleeved on the lower pressing rod 62; the bin cover 65 is engaged with the top of the temporary bin 52, and the spring 64 is located above the bin cover 65, providing the necessary reset force for the pressing process, ensuring that the pressure assembly 6 can return to its original position after each pressing, and prepare for the next feeding and pressing.

[0043] The working principle of the utility model is:

[0044] When in use, the raw material of the tablets for making the chlorine dioxide disinfectant is poured into the storage hopper 41. During the pressing and feeding process, the second motor 43 drives the auger 44 to rotate, and the rotation of the auger 44 transports the raw material falling into the conveying pipe 42 to the main pipeline 51. The continuous rotation of the auger 44 transfers the raw material of the main pipeline 51 to the internal space of the temporary bin 52 and the nozzle 53.

[0045] When the raw materials are transported into the main pipeline 51, the sealing plate 3 is moved to the bottom of the nozzle 53 by the push of the cylinder 31, thereby sealing the discharge hole 531 opened at the bottom of the nozzle 53, so as to prevent the raw materials in the nozzle 53 from leaking out of the discharge hole 531 during the feeding process;

[0046] When the feeding is completed, the eccentric wheel 21 is driven by the first motor 2 to rotate. As the eccentric wheel 21 rotates, the pressing plate 61 is squeezed to move the pressing plate 61 downward, thereby driving the piston 63 to move downward synchronously. The downward movement of the piston 63 squeezes the tablet raw materials in the temporary bin 52 and the nozzle 53 out of the discharge hole 531, and injects the tablet raw materials into the tablet pressing chamber.

[0047] During the entire feeding process, the setting of the sealing plate 3 can prevent the tablet raw materials from leaking out of the discharge hole 531. At the same time, with the cooperation of the first motor 2 and the pressure component 6, the raw materials in the temporary bin 52 and the nozzle 53 can be injected into the tablet pressing chamber at the same time, thereby improving the tablet production efficiency.

[0048] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
