Abstract
Description
Technical Field
[0001] This utility model relates to the field of sustained-release tablet processing and powder making technology, and more specifically, to a powder making device for sustained-release tablet processing. Background Technology
[0002] Sustained-release tablets are tablets that release drug slowly and at a non-constant rate in a specified release medium. Sustained-release tablets should meet the relevant requirements for sustained-release preparations and should undergo release rate testing. Unless the instructions indicate that the tablet can be broken, it should generally be swallowed whole. However, the production of sustained-release tablets requires grinding the active pharmaceutical ingredient into powder, which is then extruded using extrusion molding equipment to produce the tablets. This grinding process requires powder-making equipment; therefore, this paper proposes a powder-making device for processing sustained-release tablets.
[0003] Most existing powdering equipment for sustained-release tablets uses the method of crushing or grinding the raw drug. During the crushing or grinding process, particles that are not completely crushed are inevitable, which requires manual sieving and grinding again, which is quite troublesome. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a powdering device for processing sustained-release tablets. The technical problem to be solved is that it is difficult to screen particles that are not completely crushed.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder-making device for processing sustained-release tablets, comprising a shell:
[0006] A collection box is movably provided inside the outer shell, and discharge hoppers are respectively passed through both sides of the outer shell;
[0007] The lower part of the inner shell is provided with a powder collection device that can restrict the position of the collection box and collect the sieved powder.
[0008] The outer shell is equipped with a particle screening device that can screen the medicine powder, and the larger particles in the medicine powder are screened out and discharged.
[0009] The particle screening device includes a triangular screening frame, which is movably disposed inside the outer shell, and a perforated mesh is fixedly disposed inside the triangular screening frame.
[0010] In a preferred embodiment, the powder collecting device includes a first limiting plate and a second limiting plate, which are fixedly disposed at the lower end of the inner wall of the outer shell, and are arranged symmetrically from left to right.
[0011] In a preferred embodiment, an insertion slot is provided on one side of the outer casing, through which the collection box is inserted into the interior of the outer casing.
[0012] In a preferred embodiment, the collection box is located between the first limiting plate and the second limiting plate.
[0013] In a preferred embodiment, four sliding plates are movably provided inside the first and second limiting plates, and the upper end of the sliding plates is fixedly connected to the lower end of the triangular screening frame.
[0014] In a preferred embodiment, two vibration motors are fixedly mounted on the inner walls of the first and second limiting plates by brackets, and the two vibration motors are respectively located between the four sliding plates. The output end of the vibration motor is fixedly connected to the lower end of the triangular screening frame.
[0015] In a preferred embodiment, a motor is fixedly mounted on the upper end of the outer shell by a bracket, the output end of the motor passes through the upper end of the outer shell, a pulverizing barrel is fixedly mounted on the upper end of the inner wall of the outer shell, and a pulverizing blade is fixedly mounted on the output end of the motor, the pulverizing blade being located inside the pulverizing barrel.
[0016] In a preferred embodiment, a feeding hopper is fixedly provided at the upper end of the outer shell, one end of the feeding hopper is connected to the upper end of the crushing barrel, a timed electric valve is fixedly provided at the lower end of the crushing barrel, and a controller is fixedly provided on one side of the outer shell.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. This utility model uses a first limiting plate and a second limiting plate to restrict the collection box to the lower end of the triangular sieve frame, thus avoiding the problem of difficulty in collecting medicine powder due to the positional deviation of the collection box. When the medicine powder inside the collection box is full, pull the handle on one side of the collection box to pull the collection box out from the insertion slot.
[0019] 2. This utility model uses two vibrating motors to drive the triangular screening frame to vibrate. Therefore, when the powder and granules fall into the triangular screening frame, larger powder particles can be screened out. The larger powder particles can be discharged using the discharge hopper, thereby reducing the trouble of manual screening. The four sliding plates slide inside the first and second limiting plates, thereby improving the vibration stability of the triangular screening frame. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art of sustained-release tablet processing and powdering without creative effort are within the scope of protection of the present invention.
[0027] like Figure 1 , 2 As shown in Figure 3, this utility model provides a powder-making device for processing sustained-release tablets, including a shell 1: a collection box 7 is movably provided inside the shell 1, and discharge hoppers 8 pass through both sides of the shell 1 respectively. A motor 4 is fixedly provided at the upper end of the shell 1 by a bracket, and the output end of the motor 4 passes through the upper end of the shell 1. A crushing barrel 9 is fixedly provided at the upper end of the inner wall of the shell 1, and a crushing blade 11 is fixedly provided at the output end of the motor 4. The crushing blade 11 is located inside the crushing barrel 9. A feeding hopper 5 is fixedly provided at the upper end of the shell 1, and one end of the feeding hopper 5 is connected to the upper end of the crushing barrel 9. A timed electric valve 10 is fixedly provided at the lower end of the crushing barrel 9, and a controller 6 is fixedly provided on one side of the shell 1.
[0028] In order to confine the collection box to the lower end of the triangular sieve frame 32, a powder collection device 2 is provided at the lower end of the inner shell 1 to confine the collection box 7, which is used to limit the position of the collection box 7 and collect the sieved powder.
[0029] like Figure 4As shown, the powder collection device 2 includes a first limiting plate 21 and a second limiting plate 22. The first limiting plate 21 and the second limiting plate 22 are fixedly installed on the lower end of the inner wall of the outer shell 1. The first limiting plate 21 and the second limiting plate 22 are arranged symmetrically from left to right. An insertion slot 23 is provided on one side of the outer shell 1. The collection box 7 is inserted into the interior of the outer shell 1 through the insertion slot 23. The collection box 7 is located between the first limiting plate 21 and the second limiting plate 22. Through the first limiting plate 21 and the second limiting plate 22, the collection box 7 can be restricted to the lower end of the triangular sieve frame 32, so as to avoid the problem of difficulty in collecting the powder due to the position deviation of the collection box 7. When the powder inside the collection box 7 is full, the handle on one side of the collection box 7 is pulled to pull the collection box 7 out from the insertion slot 23.
[0030] Furthermore, in order to reduce the trouble of manually sieving the powder particles, the outer shell 1 is equipped with a particle sieving device 3 for sieving the powder particles, which is used to sieve larger particles in the powder and discharge the larger particles.
[0031] like Figure 5 As shown, the particle screening device 3 includes a triangular screening frame 32, which is movably installed inside the outer shell 1. A perforated mesh 33 is fixedly installed inside the triangular screening frame 32. Four sliding plates 24 are movably installed inside the first limiting plate 21 and the second limiting plate 22. The upper end of the sliding plate 24 is fixedly connected to the lower end of the triangular screening frame 32. Two vibrating motors 31 are fixedly installed on the inner walls of the first limiting plate 21 and the second limiting plate 22 respectively through brackets. The two vibrating motors 31 are respectively located between the four sliding plates 24. The output end of the vibrating motors 31 is fixedly connected to the lower end of the triangular screening frame 32. The two vibrating motors 31 drive the triangular screening frame 32 to vibrate. Therefore, when the powder and granules fall into the triangular screening frame 32, larger powder particles can be screened out. The larger powder particles can be discharged by the discharge hopper 8, thereby reducing the trouble of manual screening. The four sliding plates 24 slide inside the first limiting plate 21 and the second limiting plate 22, thereby improving the vibration stability of the triangular screening frame 32.
[0032] The working principle is as follows: When using this utility model, the raw medicine is put into the mixing tank 9 through the feeding hopper 5, and the motor 4 is started to drive the mixing blade 11 to rotate, thereby crushing the raw medicine into powder. Utilizing the timing effect of the timed electric valve 10, the timed electric valve 10 is automatically activated after the raw medicine inside the mixing tank 9 is mixed into powder, and the powder and granules are discharged. The granule screening device 3 can screen out the powder and larger granules. The screened powder is collected through the powder collection device 2, which reduces the trouble of manual screening of powder and improves the powder production efficiency.
[0033] In addition, it is worth noting that the control process of electronic devices such as motor 4, timed electric valve 10 and vibration motor 31 in this utility model is all realized by the controller. The control circuit and structure of the controller are mature existing technologies, so they will not be described in detail in this utility model.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
