Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, and in particular to a tablet filling device for pharmaceutical processing. Background Technology

[0002] In the pharmaceutical processing industry, from the production and shaping of tablets to their final market launch, the filling process is the core process for ensuring drug stability, extending shelf life, and achieving standardized packaging. Its level of automation and operational precision are directly related to the production capacity, efficiency, and market competitiveness of pharmaceutical manufacturers.

[0003] The tablet filling equipment currently on the market generally suffers from the following problems: the can is prone to deviation and shaking during the conveying and filling process, which can lead to tablet spillage or a decrease in filling accuracy, thus affecting production efficiency.

[0004] Therefore, it is necessary to propose a tablet filling equipment for pharmaceutical processing to solve the above problems. Utility Model Content The purpose of this invention is to provide a tablet filling equipment for pharmaceutical processing, in order to solve the problem that the can is prone to deviation and shaking during the conveying and filling process, which leads to tablet spillage or a decrease in filling accuracy and affects production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tablet filling device for pharmaceutical processing, comprising: A conveyor frame, with a conveyor belt internally connected to it, upright plates fixedly connected to both sides of the conveyor frame, a second bracket fixed between the two upright plates above the conveyor belt, a storage tank fixedly connected to the second bracket, and a discharge port opened at the bottom of the storage tank; Limiting plates are fixedly connected to the two vertical plates on their opposite sides. A clamping assembly for clamping the tank is slidably installed between the two limiting plates. The bottom of the tank is placed on the conveyor belt and moved by it. The clamping assembly includes a first clamping block and a second clamping block arranged opposite to each other, a spring telescopic rod connecting the two, and two rotating handles respectively hinged to the opposite side of the first clamping block and the second clamping block. The spring telescopic rod causes the first clamping block and the second clamping block to tend to move closer to each other. The two rotating handles are held in a clamping state by torsion springs to jointly clamp the can body without external force.

[0006] Furthermore, a sliding groove is provided on one side of the two limiting plates along their length, and a slider that cooperates with the sliding groove is fixed on the side of the first clamping block and the second clamping block that are far apart from each other.

[0007] Furthermore, both the first clamping block and the second clamping block have grooves on their opposite sides for matching the outer edge of the can's mouth, and anti-slip pads are fixedly connected in the grooves.

[0008] Furthermore, a first bracket is fixed to the top of the two limiting plates, and a dust collection component is fixedly connected to the top of the first bracket. The bottom of the dust collection component has a dust collection port corresponding to the opening position at the top of the tank.

[0009] Furthermore, the dust collection assembly includes a dust collection pump, a dust filter bag, and a dust collection pipe. One end of the dust collection pipe is connected to the dust filter bag, and the other end forms the dust collection port.

[0010] Furthermore, two photoelectric sensors for detecting the position of the tank are symmetrically arranged at the bottom of the second bracket on both sides corresponding to the discharge port.

[0011] Furthermore, the bottom end of the discharge port is connected to a flexible hose for extending into the tank body during filling.

[0012] The technical effects and advantages of this utility model are as follows: 1. The sliding groove of the limiting plate and the slider of the clamping component form a T-shaped sliding fit. Combined with the friction drive of the conveyor belt, it ensures that the tank always moves in a straight line during the conveying process, effectively avoiding deviation and shaking. At the same time, the spring telescopic rod of the clamping component and the rotating handle driven by the torsion spring form a double clamping structure, which can be adapted to tanks of different diameters and has strong clamping stability. This solves the problems of high dependence on a single tank size and easy deviation during conveying in traditional equipment.

[0013] 2. The rotating handle of the holding component provides operators with a convenient point of force for picking up and placing items. The entire process does not require direct contact with the opening area and inner wall of the tank, effectively avoiding bacterial contamination of the tank interior by the operator's hands.

[0014] 3. An additional dust extraction component is added. By generating negative pressure through a dust extraction port that is precisely aligned with the can opening, residual dust, impurities, and other contaminants inside the can can be thoroughly removed, preventing contaminants from mixing with the tablets and affecting the quality of the medicine.

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1 - Figure 3 The illustrated tablet filling equipment for pharmaceutical processing includes a conveyor frame 1, a conveyor belt 2 internally connected to the conveyor frame 1, a drive motor 3 fixedly connected to one side of the conveyor frame 1, the drive motor 3 being used to drive the conveyor belt 2, the drive motor 3 being a servo motor, model MSME-022G1, the conveyor frame 1 being a rectangular frame structure, with a drive roller and a driven roller rotatably connected inside it via bearing seats, the drive roller and the driven roller being connected by a conveyor belt 2, the conveyor belt 2 being made of food-grade rubber material, with anti-slip texture on the surface to enhance friction with the can 12.

[0022] like Figure 2 As shown, two limiting plates 5 are provided above the conveyor belt 2, and a clamping assembly 13 is slidably installed between the two limiting plates 5. The clamping assembly 13 clamps and fixes the tank body 12 inside, and the bottom end of the tank body 12 is placed on the conveyor belt 2. The limiting plate 5 is a long strip of metal plate, the length of which matches the conveying length of the conveyor frame 1. The clamping assembly 13 is slidably installed between the two limiting plates 5, and the clamping assembly 13 clamps and fixes the tank body 12 inside. The bottom end of the tank body 12 is placed on the conveyor belt 2, and the friction of the conveyor belt 2 drives the tank body 12 and the clamping assembly 13 to move synchronously.

[0023] Both sides of the conveyor frame 1 are fixedly connected to upright plates 4. Two limiting plates 5 are fixedly connected to the two upright plates 4 respectively on opposite sides. A second bracket 8 is fixedly connected between the two upright plates 4. A storage tank 9 is fixedly connected to the second bracket 8. A discharge port is opened at the bottom of the storage tank 9. A solenoid valve is installed inside the discharge port. A conveying port 10 is installed at the top of the storage tank 9.

[0024] like Figure 2 , 3 As shown, the clamping assembly 13 includes a first clamping block 14 and a second clamping block 15. A spring telescopic rod 18 is connected between the first clamping block 14 and the second clamping block 15. A rotating handle 16 is hinged to one side of the first clamping block 14 and the second clamping block 15 away from each other. The two rotating handles 16 are clamped relative to each other on the outside of the tank body 12. The first clamping block 14 and the second clamping block 15 are arranged opposite each other to form a clamping space. The spring telescopic rod 18 includes a fixed sleeve, a movable rod and a return spring. The fixed sleeve is fixedly connected to the first clamping block 14. One end of the movable rod extends into the fixed sleeve and is fixed to the second clamping block 15. The return spring is sleeved on the outside of the movable rod and its two ends abut against the fixed sleeve and the movable rod respectively, so that the first clamping block 14 and the second clamping block 15 always tend to move closer to each other.

[0025] like Figure 2 , 3 As shown, the first clamping block 14 and the second clamping block 15 are both provided with rotating grooves on opposite sides. A rotating shaft is rotatably connected inside the rotating groove. A rotating block is fixed on the outside of the rotating shaft. The rotating block and the corresponding rotating handle 16 are fixedly connected. A torsion spring is provided on the rotating shaft. Through the force of the torsion spring, the rotating handle 16 is kept in a clamping state when there is no external force.

[0026] like Figure 1 , 2 As shown, a first bracket 6 is fixed to the top of the two limiting plates 5. A dust collection component 7 is fixedly connected to the top of the first bracket 6. A dust collection port is opened at the bottom of the dust collection component 7, and the dust collection port corresponds to the opening at the top of the tank 12. The dust collection component 7 includes a dust collection pump, a dust filter bag, and a dust collection pipe. The suction end of the dust collection pump is connected to the dust filter bag, and the exhaust end extends to the outside or the purification device. One end of the dust collection pipe is connected to the dust filter bag, and the other end forms a dust collection port. The dust collection port is suspended above the conveyor belt 2 and corresponds to the position of the opening at the top of the tank 12. The inner diameter of the dust collection port is slightly larger than the inner diameter of the opening of the tank 12 to ensure that the dust collection range covers the entire tank opening.

[0027] The two limiting plates 5 each have a sliding groove 11 on one side of the opposite side along the length direction. The first clamping block 14 and the second clamping block 15 each have a slider 17 fixed on one side away from each other. The slider 17 is slidably installed inside the corresponding sliding groove 11.

[0028] like Figure 2 , 3As shown, the first clamping block 14 and the second clamping block 15 each have a groove on their opposite sides. The groove matches the outer edge of the bottle mouth of the can 12, and an anti-slip pad is fixedly connected inside the groove.

[0029] The bottom of the second support 8 is equipped with two photoelectric sensors symmetrically arranged on both sides of the discharge port corresponding to the bottom of the second support 8. The detection direction of the sensors is towards the conveyor belt 2, which is used to accurately detect the position of the tank 12.

[0030] It should be noted that a flexible hose can be connected to the bottom of the discharge port. When the tank 12 reaches the discharge port, the flexible hose will intersect with the mouth of the tank 12 and extend into the tank 12 to facilitate material conveying. This device is also equipped with a control system, which consists of a PLC controller, a touch screen display, and relays. The PLC controller is electrically connected to the drive motor 3, the dust collection component 7, the electromagnetic flow valve, and the photoelectric sensor. The touch screen display is used to set the filling parameters (such as filling volume and conveying speed) and display the operating status of the equipment. The relays are used to control the start and stop of each actuator.

[0031] Working principle: Before using this equipment, the operator first sets the conveying speed of the conveyor belt 2, the opening time of the electromagnetic flow valve (corresponding to the tablet filling volume), and the start-up time of the dust collection component 7 through the touch screen display. After starting the equipment, the drive motor 3 drives the conveyor belt 2 to rotate at a constant speed, and at the same time, the dust collection component 7 starts and enters the standby state.

[0032] The operator pulls the two rotating handles 16 outwards. The rotating handles 16 rotate around the pivot and compress the torsion spring. At this time, the first clamping block 14 and the second clamping block 15 can automatically adjust the distance according to the diameter of the tank body 12 under the action of the spring telescopic rod 18, placing the tank body 12 in the groove between the two clamping blocks. After releasing the rotating handles 16, the torsion spring returns to its original position, causing the rotating handles 16 to clamp the outside of the tank body 12. At the same time, the restoring force of the spring telescopic rod 18 makes the grooves of the two clamping blocks fit against the tank body 12, achieving a stable clamping of the tank body 12. Then, the slider 17 of the clamping assembly 13 is aligned with the sliding groove 11 of the limiting plate 5 and pushed in, so that the bottom end of the tank body 12 contacts the conveyor belt 2. The friction of the conveyor belt 2 causes the tank body 12 and the clamping assembly 13 to move at a constant speed along the sliding groove 11.

[0033] When the tank 12 moves directly below the suction port of the dust collection component 7, the PLC controller controls the dust collection pump to increase the suction power according to the speed signal of the conveyor belt 2. The negative pressure generated by the suction port sucks the dust and impurities remaining inside the tank 12 into the dust filter bag, completing the cleaning work of the tank 12. After the cleaning time reaches the preset value, the dust collection pump resumes standby suction power.

[0034] When the tank 12 continues to move below the second support 8, the two photoelectric sensors simultaneously detect the tank 12 and send a signal to the PLC controller. The PLC controller immediately controls the electromagnetic flow valve to open, and the tablets in the storage tank 9 fall into the tank 12 at a uniform speed through the discharge port. When the opening time of the electromagnetic flow valve reaches the preset value (corresponding to the set filling amount), the PLC controller controls the electromagnetic flow valve to close, completing the tablet filling.

[0035] After filling, the can 12 moves to the end of the conveyor frame 1 along the conveyor belt 2. The operator then pulls the rotating handle 16 outward to remove the can 12 from the clamping assembly 13. The entire process of picking up and placing the can does not require direct contact with the opening and inner wall of the can 12, thus avoiding bacterial contamination. The clamping assembly 13 can remain on the limiting plate 5 and return to its initial position as the conveyor belt 2 rotates in the opposite direction, for use in clamping and fixing subsequent cans 12, enabling continuous production.

[0036] 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 principles of the present utility model should be included within the protection scope of the present utility model.
