Description

Technical Field

[0001] This utility model relates to the field of capsule filling technology, specifically a capsule filling machine. Background Technology

[0002] The capsule filling machine uses a microcomputer programmable controller, which can simultaneously perform capsule dispensing, capsule separation, filling, waste capsule removal, capsule locking, and capsule ejection, reducing labor intensity, improving production efficiency, and meeting pharmaceutical hygiene requirements. It generally adopts an automatic intermittent rotary motion form, with a rotary table installed in the center of the workbench. Each rotation has a short pause time. The rotary table transports capsules to various workstations around the rotary table. During the short pause time at each station, various operations such as capsule dispensing, capsule separation, filling, waste capsule removal, capsule locking, capsule ejection, and mold cleaning are performed automatically at the same time. After the capsule filling is completed, the capsules are fed into the storage box through the feeding plate.

[0003] The existing patent authorization announcement number CN219148549U discloses a capsule filling machine. By setting up a diversion adjustment mechanism, rotating the knob adjusts the rotating plate, blocking any one of the guide grooves to achieve diversion, causing the capsules to fall into the first storage box. After the rotary table rotates once, it is adjusted to make the capsules fall into the second storage box. The capsules in the first storage box are weighed by an electronic scale, and the quality of the capsules is observed based on the weight of the capsules, thereby achieving the effect of screening capsules. This avoids the need to consume a lot of time during screening due to too many capsules, thus improving efficiency.

[0004] When using the above-mentioned patent, the capsules are filled in batches, which requires controlling the number of capsules falling into the storage box. When the number of capsules is small, defective products need to be manually removed. When the number of capsules is large, it is impossible to determine the number of capsules, which affects the weighing and observation effect. It is inconvenient to manually screen them. Furthermore, it is impossible to visually judge and remove empty capsules, which requires manual removal, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a capsule filling machine to solve the problems mentioned in the background art, which require manual removal of defective capsules when the number of capsules is small, and make it impossible to determine the number of capsules when the number of capsules is large, thus affecting the weighing and observation effect, making manual screening inconvenient, and making it impossible to visually judge and remove empty capsules, which requires manual removal and is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a capsule filling machine, comprising a capsule filling machine body, a discharge channel and a separation component fixedly installed on the front side of the capsule filling machine body, and a waste removal component fixedly installed on the top of the separation component below the discharge channel; the waste removal component includes a waste removal frame, an upper mounting frame and a lower mounting frame fixedly installed on the front and rear sides of the waste removal frame respectively, and a screen one and a screen two arranged opposite to each other movably hinged on the inner sides of the upper mounting frame and the lower mounting frame respectively, and a screen located on the screen two being rotatably installed inside the waste removal frame. The rotating shafts below screen one and screen two are equipped with cams fixedly mounted on their exteriors. A guide plate located below screen two is fixedly mounted inside the waste rejection frame. Discharge ports corresponding to screen one, screen two, and the guide plate are respectively opened on the left and right sides of the waste rejection frame. Reset components are fixedly mounted at the bottom of screen one and screen two. The separation component includes a separation box. A connected fan is fixedly mounted on the left side of the separation box. A feed channel located on the left side of the waste rejection frame is fixedly mounted on the top of the separation box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After the capsules are filled, they fall onto screen one through the discharge channel. The external cam rotates through the rotating shaft, causing screen one and screen two to move up and down at high speed. The larger and smaller defective capsules are screened out through screen one and screen two respectively. The qualified capsules fall into the feeding channel. The fan blows air into the separation box, which acts on the falling capsules and blows the empty capsules to the collection trough two for discharge. The qualified capsules are discharged along the collection trough one. Thus, the capsules can be automatically screened without manual removal, improving efficiency.

[0015] 2. The capsules enter the feeding channel, slide down the shrinking section and fall downwards at the outlet. The dual-axis motor drives the disc to rotate. The disc taps the outer wall of the shrinking section, causing slight vibration to prevent the capsules from getting stuck.

[0022] The technical solutions of the present utility model 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 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a capsule filling machine, including a capsule filling machine body 1. A discharge channel 2 and a separation component 4 are fixedly installed on the front side of the capsule filling machine body 1. A waste removal component 3 located below the discharge channel 2 is fixedly installed on the top of the separation component 4. The waste removal component 3 includes a waste removal frame 31. An upper mounting frame 32 and a lower mounting frame 33 are fixedly installed on the front and rear sides of the waste removal frame 31, respectively. A screen 1 34 and a screen 2 35 are movably hinged to the inner sides of the upper mounting frame 32 and the lower mounting frame 33, respectively. A rotating shaft 36 located below the screen 1 34 and the screen 2 35 are rotatably installed inside the waste removal frame 31. A cam 37 is fixedly installed on the outside of the rotating shaft 36. A guide plate 38 located below the screen 2 35 is fixedly installed inside the waste removal frame 31. Discharge outlets corresponding to the screen 1 34, the screen 2 35, and the guide plate 38 are opened on the left and right sides of the waste removal frame 31, respectively. The bottom of both screen 34 and screen 35 is fixedly equipped with a reset component 312; the separation component 4 includes a separation box 41, a fan 42 is fixedly installed on the left side of the separation box 41, and a feeding channel 43 located on the left side of the waste rejection frame 31 is fixedly installed on the top of the separation box 41. The bottom of the separation box 41 is provided with a collection trough 1 44 and a collection trough 2 45. After the capsules are filled, they fall onto screen 34 through the discharge channel 2. The external cam 37 is rotated by the rotating shaft 36, causing screen 34 and screen 2 35 to move up and down at high speed. The larger and smaller defective capsules are screened out through screen 34 and screen 2 35 respectively. The qualified capsules fall into the feeding channel 43. The fan 42 blows air into the separation box 41, which acts on the falling capsules and blows the empty capsules to the collection trough 2 45 for discharge. The qualified capsules are discharged along the collection trough 1 44. Thus, the capsules can be automatically screened without manual rejection, improving efficiency.

[0024] Synchronous pulleys 310 are fixedly installed on the rear side of each rotating shaft 36, located outside the waste rejection frame 31. A synchronous belt 311 is movably installed on the outside of the synchronous pulleys 310. A drive motor 39 connected to one of the rotating shafts 36 is fixedly installed on the front side of the waste rejection frame 31. Starting the drive motor 39 will drive the rotating shaft 36 connected to it to rotate. The rotating shafts 36 below the screen one 34 and screen two 35 are driven by the synchronous pulleys 310 and the synchronous belt 311 to achieve synchronous rotation. The two rotating shafts 36 drive the external cam 37 to rotate, which drives the screen one 34 and screen two 35 to move and screen out the capsules. The movement frequency and amplitude of the screen one 34 and screen two 35 are precisely designed to ensure efficient separation of capsules and avoid capsule accumulation or jamming.

[0025] Both screen 1 34 and guide plate 38 are inclined downwards toward the right side of the waste rejection frame 31, while screen 2 35 is inclined downwards toward the left side of the waste rejection frame 31. The inclined design of screen 1 34 and screen 2 35 allows the capsules to slide down naturally during the screening process, reducing manual intervention. The inclined setting of screen 1 34 and guide plate 38 guides unqualified capsules to the right side of the waste rejection frame 31 for centralized discharge, which is convenient for collection and processing. Screen 2 35 guides qualified capsules to the left side of the waste rejection frame 31, ensuring that the separation process is efficient and orderly.

[0026] The aperture of sieve 1 34 is larger than that of sieve 2 35. The larger aperture of sieve 1 34 is mainly used to screen out larger defective capsules, while the smaller aperture of sieve 2 35 is used to screen out smaller defective capsules. This allows for the screening out of defective capsules of different sizes, ensuring that the capsules that remain in the end fully meet the standards.

[0027] Please see Figure 3 and Figure 4The reset assembly 312 includes a connecting plate 3121 fixedly connected to the outside of screen one 34 and screen two 35. A guide post 3122, which is locked within the upper mounting bracket 32 ​​and lower mounting bracket 33, is fixedly connected to the bottom of the connecting plate 3121. A limit piece 3123 is fixedly connected to the bottom of the guide post 3122. A buffer spring 3124 is movably sleeved on the lower part of the guide post 3122. When screen one 34 and screen two 35 move, they drive the connecting plate 3121 to move, causing the arc-shaped guide post 3122 to be positioned on the upper mounting bracket 32 ​​and lower mounting bracket 33 respectively. The guide column 3122 slides within the frame 33, driving the limiting plate 3123 to move and thus compress the buffer spring 3124. The buffer spring 3124 applies tension to screen one 34 and screen two 35, enabling screen one 34 and screen two 35 to remain stable during movement and reducing deviations caused by vibration. The elasticity of the buffer spring 3124 not only effectively absorbs the impact force generated when screen one 34 and screen two 35 move, but also helps screen one 34 and screen two 35 to quickly reset after each movement, thereby improving the continuity and efficiency of equipment operation.

[0028] Please see Figure 2 and Figure 5 The feeding channel 43 includes an outer section 431 and a converging section 432 located below the outer section 431. An outlet 433 is provided at the bottom of the converging section 432. A dual-axis motor 434 is fixedly installed on the outside of the converging section 432. A disc 435 is fixedly installed on the outside of the output shaft of the dual-axis motor 434. A hammer 436 is fixedly connected to the outside of the disc 435. The capsule enters the feeding channel 43, slides down the converging section 432 and falls downward at the outlet 433. The dual-axis motor 434 drives the disc 435 to rotate. The disc 435 strikes the outer wall of the converging section 432, causing slight vibration to prevent the capsule from getting stuck. The blower 42 blows air vertically downward towards the capsule in a planar manner to ensure accurate capsule screening and improve screening accuracy.

[0029] The hammer 436 is made of rubber and is arranged in a ring with equal intervals. The rubber material of the hammer 436 has good elasticity and wear resistance, which can effectively reduce damage to the outer wall of the shrinkage section 432 and reduce the noise generated during operation. The ring-shaped and equidistant distribution design ensures the uniformity of vibration and avoids the occurrence of insufficient or excessive local vibration, thereby further improving the flowability of the capsule in the feed channel 43.

[0030] Working principle: Empty capsules are placed inside the capsule filling machine body 1, and the raw materials to be filled are placed inside the filling machine. When the rotary table rotates, it drives the external clamps to rotate, and the capsules are filled by the capsule filling machine and then filled by the filling machine.

[0031] After the capsule filling is completed, it falls through the discharge channel 2 onto the screen 34 inside the waste removal frame 31. The drive motor 39 at the front of the waste removal frame 31 is activated, driving the connected rotating shaft 36 to rotate. The rotating shafts 36 below the screens 34 and 35 rotate synchronously via a synchronous pulley 310 and a synchronous belt 311. The two rotating shafts 36 drive the external cams 37 to rotate, which in turn push the bottoms of the screens 34 and 35, causing them to move up and down at high speed along the hinge points inside the upper and lower mounting frames 32 and 33, respectively. This causes the capsules falling onto the screen 34 to shake downwards along the screen. Qualified capsules pass through screen 1 34 and fall onto screen 2 35 below. Larger defective products are discharged from the right side of the rejection frame 31 along screen 1 34. Similarly, smaller defective products in the capsules pass through screen 2 35 and fall onto the guide plate 38 along the guide plate 38 and are discharged from the right side of the rejection frame 31. Qualified capsules are located on screen 2 35 and move towards the feeding channel 43 and fall into the feeding channel 43. The blower 42 blows air into the separation box 41 to the capsules falling from the feeding channel 43. Since the empty capsules are lighter, they are blown by the air to the collection trough 2 45 and fall out. Qualified capsules fall out along the collection trough 1 44.

[0032] After the capsules fall into the feed channel 43, they converge along the shrinkage section 432 to the outlet 433 and fall downwards. The dual-shaft motor 434 drives the disc 435 to rotate, and the disc 435 strikes the outer wall of the shrinkage section 432 to produce a small vibration, which prevents the capsules from clogging. The blower 42 blows air vertically towards the surface where the capsules are formed to ensure accurate screening. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
