Description

Technical Field

[0001] This utility model relates to the field of tablet press technology, specifically to a pharmaceutical tablet press with a powder collection function. Background Technology

[0002] Pharmaceutical tableting is a pharmaceutical process in which drug raw materials and excipients are mixed and then compressed into tablets under high pressure using a tableting machine. This process not only facilitates the storage, transportation, and administration of drugs, but also optimizes drug stability and efficacy by controlling tablet hardness, disintegration time, and release characteristics.

[0003] Chinese patent CN221737180U discloses a pharmaceutical tablet compressor with powder collection function. The tablet compressor includes a support frame, a first hydraulic cylinder located at the top center of the support frame, and a pressure plate whose stroke end passes through the support frame and is fixedly connected. Multiple pressure rods arranged in a matrix are located below the pressure plate. A U-shaped fixing plate is located at the lower end of the support frame, and a dust collection trough is located on the outside of the top rod on the U-shaped fixing plate. A dust collection box is located on one side of the U-shaped fixing plate, and the dust collection trough and the dust collection box are connected by a conduit. A filter screen is installed inside the dust collection box, and a fan is located below the filter screen. This tablet compressor has a simple structure, is easy to operate, and can automatically complete both feeding and unloading. Powder falling during tablet compressing is easily collected, avoiding powder waste and effectively improving resource utilization.

[0004] The tablet compressor described in the aforementioned patent document uses a filter to sieve powder. Although a fan is installed below the filter, powder still accumulates on the filter, eventually clogging the mesh and preventing the filter from effectively sieving the powder. Therefore, a tablet compressor with a powder collection function is proposed. Utility Model Content

[0005] To address the aforementioned issues, a pharmaceutical tablet compressor with a powder collection function is provided. By installing a brush at the bottom of the moving frame, when the moving frame moves, it drives the brush to reciprocate along the upper surface of the housing. As the brush moves, it sweeps away the powder accumulated in the feed port, thus solving the problem of powder clogging the feed port and causing poor sorting effect of the inclined plate.

[0006] To address the problems of existing technologies, this application provides a pharmaceutical tableting machine with a powder collection function, including a frame, a worktable mounted on the frame, a material trough mounted on the upper part of the worktable, and a residual material recovery mechanism mounted on one side of the worktable. A tableting template is embedded in the worktable, and the upper surface of the tableting template is at the same height as the upper surface of the worktable. The material trough can move horizontally back and forth along the upper surface of the worktable, and a residual material pusher is fixed to one side of the material trough. The residual material recovery mechanism includes a housing fixed to one side of the worktable, with symmetrically fixed side plates for blocking material on one side of the housing. The bottom of the side plates contacts the upper surface of the worktable. A first discharge pipe and a second discharge pipe are provided at the bottom of the housing. An inclined plate is fixedly fixed to the top of the first discharge pipe, and several discharge ports are equidistantly opened on the inclined plate. A cleaning mechanism for cleaning the discharge ports is also provided inside the housing. The cleaning mechanism includes a movable frame that can move back and forth along its upper surface, and a brush that can clean residual powder in the discharge ports is fixed to one side of the movable frame.

[0007] As one technical solution of this application, an arc-shaped groove is provided on one side of the scrap pusher plate, and the inner surface of the arc-shaped groove is arc-shaped.

[0008] As one technical solution of this application, a rotatable lead screw is horizontally installed inside the housing; a servo motor is fixed on the outer wall of the housing, and the output end of the servo motor is fixedly connected to the end of the lead screw; a threaded hole is provided on the movable frame that can be fitted onto the lead screw, and the threaded hole is threadedly engaged with the lead screw.

[0009] As one technical solution of this application, a plurality of second limiting slide rods for limiting the movement frame are provided on the side of the housing near the lead screw. The two ends of the second limiting slide rods are fixed to the inner wall of the housing. The movement frame is also provided with a number of sliding holes corresponding to the number of the second limiting slide rods. The sliding holes are sleeved on the second limiting slide rods and can move along the central axis of the second limiting slide rods.

[0010] As one technical solution of this application, a fixed frame is fixed on the side of the workbench surface away from the waste material recycling mechanism, and a cylinder for driving the material trough to move horizontally is fixed on the top of the fixed frame. The output end of the cylinder is fixedly connected to the side of the material trough away from the waste material push plate.

[0011] As one technical solution of this application, the two sides of the fixing frame are symmetrically fixed with first limiting slide rods for limiting the material trough. The end of the first limiting slide rod away from the fixing frame is fixed with a fixing seat, and the bottom of the fixing seat is installed on the worktable. The two sides of the material trough are symmetrically fixed with sliding sleeves that can be fitted onto the first limiting slide rods, and the sliding sleeves slide in cooperation with the first limiting slide rods.

[0012] The advantages of this utility model compared to the prior art are: 1. This application solves the problem of powder clogging the feed port and resulting in poor sorting effect of the inclined plate by setting a brush at the bottom of the moving frame. When the moving frame moves, the moving frame will drive the brush to move back and forth along the upper surface of the shell. When the brush moves, the brush will sweep off the powder accumulated in the feed port, thus solving the problem of powder clogging the feed port and resulting in poor sorting effect of the inclined plate. 2. This application addresses the issue of material waste by creating an arc-shaped groove on one side of the waste material pusher plate and setting the inner surface of the arc-shaped groove to be circular. When the waste material pusher plate pushes the waste material, the waste material not only rolls forward along the inner wall of the arc-shaped groove, but also concentrates towards the center of the waste material pusher plate while moving, effectively avoiding the problem of excessive material dispersion when the waste material pusher plate pushes the waste material.

Detailed Implementation

[0015] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figures 1-7 As shown, a pharmaceutical tableting machine with powder collection function includes a frame 1, a worktable 2 mounted on the frame 1, a material trough 3 mounted on the upper end of the worktable 2, and a residual material recovery mechanism 4 mounted on one side of the worktable 2. A tableting template 21 is embedded in the worktable 2, and the upper surface of the tableting template 21 is at the same height as the upper surface of the worktable 2. The material trough 3 can move horizontally back and forth along the upper surface of the worktable 2, and a residual material pusher 32 is fixed on one side of the material trough 3. The residual material recovery mechanism 4 includes a housing 41 fixed on one side of the worktable 2, and symmetrically fixed on one side of the housing 41 are tools for blocking material. The side plate 45 has its bottom in contact with the upper surface of the workbench 2. The bottom of the housing 41 is provided with a first discharge pipe 42 and a second discharge pipe 43. The top of the first discharge pipe 42 is fixed with an inclined plate 44. Several discharge ports 441 are equally spaced on the inclined plate 44. The housing 41 is also provided with a cleaning mechanism 6 for cleaning the discharge ports 441. The cleaning mechanism 6 includes a movable frame 61 that can move back and forth along its upper surface. A brush 64 that can clean the powder residue in the discharge ports 441 is fixed on one side of the movable frame 61.

[0017] The material in the trough 3 is fed to the top of the tableting template 21 by the horizontal movement of the trough 3, so that the material in the trough 3 automatically falls into the tableting template 21. During the movement of the trough 3, the trough 3 can also drive the residual material pusher 32 to move synchronously. At this time, the residual material pusher 32 will push the material remaining on the upper surface of the tableting template 21 into the housing 41. Then, the material will slide down the upper surface of the inclined plate 44. During this process, powder particles will fall into the first feeding pipe 42 through the feeding port 441 opened on the inclined plate 44, and larger powder particles will continue to move down the inclined plate 44 into the second feeding pipe 43. This achieves the sorting of powder. To prevent powder from accumulating and clogging the discharge port 441, a brush 64 is installed at the bottom of the moving frame 61. When the moving frame 61 moves, it drives the brush 64 to move back and forth along the upper surface of the housing 41. As the brush 64 moves, it sweeps away the powder accumulated in the discharge port 441, thus solving the problem of powder clogging the discharge port 441 and causing poor sorting effect of the inclined plate 44.

[0018] See Figure 4 As shown, an arc-shaped groove 33 is provided on one side of the scrap push plate 32, and the inner surface of the arc-shaped groove 33 is arc-shaped.

[0019] By creating an arc-shaped groove 33 on one side of the scrap material pusher 32 and setting the inner side of the arc-shaped groove 33 to be arc-shaped, when the scrap material pusher 32 pushes the scrap material to move, the scrap material will not only roll forward along the inner wall of the arc-shaped groove 33, but will also concentrate towards the center of the scrap material pusher 32 while moving, effectively avoiding the problem of the material being too dispersed when the scrap material pusher 32 pushes the scrap material.

[0020] See Figure 5 , Figure 6 and Figure 7 As shown, a rotatable lead screw 46 is horizontally mounted inside the housing 41; a servo motor 48 is fixed to the outer wall of the housing 41, and the output end of the servo motor 48 is fixedly connected to the end of the lead screw 46; see also Figure 5 , Figure 6 and Figure 7 As shown, the movable frame 61 has a threaded hole 62 that can be fitted onto the lead screw 46, and the threaded hole 62 is threadedly engaged with the lead screw 46.

[0021] To enable effective movement of the movable frame 61, a threaded hole 62 is made on the movable frame 61, and then the threaded hole 62 is installed on the lead screw 46. When the servo motor 48 is started, the servo motor 48 drives the lead screw 46 to rotate. As the lead screw 46 rotates, it drives the threaded hole 62 that meshes with it. The movable frame 61 is moved by the cooperation of the threaded hole 62 and the lead screw 46, thus ensuring movement.

[0022] See Figure 5 , Figure 6 and Figure 7 As shown, several second limiting slide rods 47 are provided inside the housing 41 near the lead screw 46 to limit the movement of the movable frame 61. The two ends of the second limiting slide rods 47 are fixed to the inner wall of the housing 41. (See also...) Figure 5 , Figure 6 and Figure 7 As shown, the movable frame 61 is also provided with a number of sliding holes 63 corresponding to the number of the second limiting slide rod 47. The sliding holes 63 are fitted on the second limiting slide rod 47 and can move along the central axis of the second limiting slide rod 47.

[0023] To ensure the stability of the movable frame 61, several second limiting slide rods 47 are horizontally fixed to the housing 41, and then the movable frame 61 is installed on the second limiting slide rods 47 through the sliding holes 63. When the movable frame 61 moves, it will move along the central axis of the second limiting slide rods 47 through the sliding holes 63. The stability of the movable frame 61 is ensured by the sliding cooperation between the second limiting slide rods 47 and the sliding holes 63.

[0024] See Figure 2 and Figure 3 As shown, a fixed frame 22 is fixed on the side of the upper surface of the workbench 2 away from the waste material recycling mechanism 4. A cylinder 5 for driving the material trough 3 to move horizontally is fixed on the top of the fixed frame 22. The output end of the cylinder 5 is fixedly connected to the side of the material trough 3 away from the waste material push plate 32.

[0025] To achieve effective movement of the material trough 3, the cylinder 5 is fixed to the top of the mounting bracket 22, and then the output end of the cylinder 5 is fixed to the material trough 3. Then the cylinder 5 is activated. When the cylinder 5 is activated, the output end of the cylinder 5 extends or retracts, so that the cylinder 5 drives the material trough 3 to move horizontally along the upper surface of the worktable 2 through the extension or retraction of the output end.

[0026] See Figure 2 and Figure 3 As shown, the two sides of the fixed frame 22 are symmetrically fixed with first limiting slide rods 24 for limiting the material trough 3. The end of the first limiting slide rod 24 away from the fixed frame 22 is fixed with a fixed seat 23. The bottom of the fixed seat 23 is installed on the worktable 2. The two sides of the material trough 3 are symmetrically fixed with sliding sleeves 34 that can be fitted onto the first limiting slide rod 24. The sliding sleeves 34 slide in cooperation with the first limiting slide rod 24.

[0027] To ensure the stability of the material trough 3, sliding sleeves 34 are fixed on both sides of the material trough 3, and then the sliding sleeves 34 are fitted onto the first limiting sliding rod 24. When the material trough 3 moves, the material trough 3 will drive the sliding sleeves 34 to move along the central axis of the first limiting sliding rod 24. The sliding sleeves 34 and the first limiting sliding rod 24 work together to limit the material trough 3, effectively preventing the material trough 3 from shifting during movement.

[0028] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
