Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a compound calcium carbonate granule dual-head filling equipment. Background Technology

[0002] In the production of pharmaceutical products, compound calcium carbonate granules, as a common calcium supplement, require precise dosage packaging so that patients can take it as needed. Therefore, the production line needs to fill a certain dose of compound calcium carbonate granules into individual packaging cans to achieve an automated and standardized packaging process. Currently, the industry generally uses automatic granule filling machines to complete this process, improving production efficiency and packaging accuracy.

[0003] However, existing granule filling equipment still has many shortcomings in practical applications. First, traditional filling machines typically have only one filling head, meaning they can only fill one container per operation, resulting in low overall filling efficiency and making it difficult to meet the needs of large-scale continuous production. Second, during the feeding process, if too much granular material is added to the hopper at once to reduce the feeding frequency, it can easily cause blockages in the discharge pipe below due to excessive material accumulation or poor flow. This not only affects metering accuracy but also frequently triggers equipment shutdowns for cleaning, further reducing production efficiency and equipment operational stability. Utility Model Content

[0004] In view of the problems in related technologies, this utility model proposes a compound calcium carbonate granule dual-head filling device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A compound calcium carbonate granule double-head filling device includes a support base, a conveying cylinder connected to the top of the support base, a discharge pipe connected to the top of the conveying cylinder, a hopper connected to the top of the discharge pipe, a support plate connected to one end of the conveying cylinder, a drive motor mounted on the surface of the support plate, a drive shaft connected to the output end of the drive motor, the drive shaft being rotatably installed inside the conveying cylinder, a bidirectional discharge mechanism between the conveying cylinder and the support base, conveyors mounted on both sides of the support base, and a medicine container clamping mechanism on the surface of the conveyors.

[0007] Furthermore, in order to achieve bidirectional discharge inside the conveying cylinder, the bidirectional discharge mechanism includes spiral conveying blades symmetrically installed on both sides of the drive shaft, a driving bevel gear connected to the middle of the drive shaft, a stirring rod rotatably installed inside the hopper, and a driven bevel gear connected to the end of the stirring rod, with the driven bevel gear meshing with the driving bevel gear.

[0008] Furthermore, in order to weigh and quantitatively discharge the calcium carbonate particles discharged from the conveying cylinder, a feeding pipe is connected to both sides of the bottom of the conveying cylinder, a positioning frame is connected to both sides of the support base, a quantitative hopper is connected to the end of the positioning frame, a second drive motor is installed on one side of the quantitative hopper, a weighing cylinder is connected to the output end of the second drive motor, and a pressure sensor is installed at the bottom of the weighing cylinder.

[0009] Furthermore, in order to block the end of the discharge pipe when the weighing cylinder rotates to discharge material, electric telescopic rods are installed on both sides of the bottom of the conveying cylinder, and the ends of the electric telescopic rods are connected to baffle plates.

[0010] Furthermore, in order to clamp and transport the packaging cans of calcium carbonate granules, the can clamping mechanism includes a positioning rod mounted on the surface of the conveyor, a carrier box connected to the surface of the positioning rod, return springs connected to both sides inside the carrier box, and a clamping plate connected to the end of the return spring.

[0011] Furthermore, in order to control the various electrical components within the device, a PLC controller is installed on one side of the support base.

[0012] Furthermore, to facilitate the overall movement of the equipment, the bottom sides of the support base are fixedly connected to the conveyor, and the bottom of the conveyor is equipped with casters.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the bidirectional discharge mechanism, when the drive motor drives the drive shaft to rotate, the two symmetrically mounted spiral conveying blades on the surface of the drive shaft can rotate synchronously in the conveying cylinder, realizing bidirectional discharge of the compound calcium carbonate granules falling into the conveying cylinder. After bidirectional discharge, the discharged material is weighed and quantitatively discharged, so that the equipment can simultaneously perform parallel filling operations on two calcium carbonate granule packaging tanks, effectively increasing the filling speed by nearly 100%, greatly improving production efficiency, meeting the needs of large-scale continuous industrial production, and shortening the production cycle.

[0015] 2. Through the bidirectional discharge mechanism, during the material conveying process of the drive shaft rotation, the active bevel gear on its surface can drive the driven bevel gear at the bottom of the stirring rod to rotate, so that the stirring rod can continuously rotate and stir in the hopper and discharge pipe, effectively preventing the accumulation and blockage inside the hopper and discharge pipe, and ensuring the continuity and stability of the filling process.

[0026] 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.

[0027] According to an embodiment of the present invention, a dual-head filling device for compound calcium carbonate granules is provided.

[0028] like Figures 1-3 As shown, a compound calcium carbonate granule double-head filling device according to an embodiment of the present invention includes a metal support base 1, a conveying cylinder 2 connected to the top of the support base 1, a discharge pipe 3 connected to the top of the conveying cylinder 2, and a hopper 4 connected to the top of the discharge pipe 3 for simultaneously holding a certain volume of compound calcium carbonate granules. The calcium carbonate granules in the hopper 4 can enter the conveying cylinder 2 through the discharge pipe 3. An arc-shaped support plate 5 is connected to one end of the conveying cylinder 2, and a drive motor 6 is mounted on the surface of the support plate 5. The output end of the drive motor 6 is connected to a drive shaft. 7. The drive shaft 7 is rotatably installed inside the conveying cylinder 2. A bidirectional discharge mechanism 8 is provided between the conveying cylinder 2 and the support base 1 to realize bidirectional transportation and discharge of calcium carbonate entering the conveying cylinder 2, and to simultaneously fill two calcium carbonate granule packaging cans. Conveyors 9 are installed on both sides of the support base 1. The conveyor 9 is a belt conveyor 9. The drive belt is driven to rotate by a servo motor to realize the transportation of items on the surface of the conveyor belt. A medicine can clamping mechanism 10 is provided on the surface of the conveyor 9 to stably clamp the calcium carbonate granule packaging can and transport it through the conveyor 9.

[0029] like Figures 3-6As shown, the bidirectional discharge mechanism 8 includes spiral conveying blades 801 symmetrically mounted on both sides of the drive shaft 7. The drive shaft 7 is driven to rotate within the conveying cylinder 2 by a drive motor 6, causing the two spiral conveying blades 801 on the surface of the drive shaft 7 to rotate synchronously, thereby achieving bidirectional conveying of calcium carbonate particles within the conveying cylinder 2. A driving bevel gear 802 is connected to the middle of the drive shaft 7. A stirring rod 803 is rotatably mounted inside the hopper 4, and a driven bevel gear 804 is connected to the end of the stirring rod 803. The driven bevel gear 804 meshes with the driving bevel gear 802. The outer sides of the wheel 802 and the driven bevel gear 804 are provided with protective shells, and the protective shells are rotatably connected to the stirring rod 803 and the drive shaft 7, respectively. When the drive shaft 7 and the spiral conveying blade 801 rotate to convey material, the driving bevel gear 802 can drive the driven bevel gear 804 and the stirring rod 803 to rotate, so that the stirring rod 803 stirs the calcium carbonate particles accumulated in the hopper 4 and the discharge pipe 3, preventing blockage during material discharge; the bottom sides of the conveying cylinder 2 are connected to the discharge pipe 805, and the sides of the support base 1 are connected to a pair of positioning frames 806, the end of each positioning frame 806 is connected to A metering hopper 807 is connected to a conveyor belt. A drive motor 808 is installed on one side of the metering hopper 807. The output end of the drive motor 808 is connected to a weighing cylinder 809. A pressure sensor 810 is installed at the bottom of the weighing cylinder 809. The material in the conveying cylinder 2 is sent to both ends by the screw conveyor blades 801 and then falls into the metering hopper 807 through the discharge pipe 805. The weighing cylinder 809 and the pressure sensor 810 in the metering hopper 807 can weigh and detect the falling material. When the mass of the falling material reaches the single filling requirement, the drive motor 808 can drive the weighing cylinder 809 to start filling. 09 rotates to allow a fixed mass of material to fall and be discharged; electric telescopic rods 811 are installed on both sides of the bottom of the conveying cylinder 2, and the ends of the electric telescopic rods 811 are connected to baffle plates 812. When the weighing cylinder 809 needs to rotate downward, the electric telescopic rods 811 can quickly drive the baffle plates 812 to move to the bottom of the discharge pipe 805, thereby blocking the end of the discharge pipe 805 and preventing the material from continuing to fall. When the weighing cylinder 809 rotates downward again, the electric telescopic rods 811 can drive the baffle plates 812 to move away from the bottom of the discharge pipe 805, and the material discharge can continue.

[0030] like Figure 2 and Figure 7As shown, the medicine container clamping mechanism 10 includes a plurality of positioning rods 1001 mounted on the surface of the conveyor 9. The positioning rods 1001 are evenly distributed on the conveyor belt of the conveyor 9. A carrier box 1002 is connected to the surface of the positioning rods 1001. The interior of the carrier box 1002 is used to hold the calcium carbonate granule packaging container. Return springs 1003 are connected to both sides inside the carrier box 1002. The ends of the return springs 1003 are connected to clamping plates 1004. When it is necessary to fill the calcium carbonate granule packaging container, the packaging container is pressed and placed on the carrier box 1002. Inside, the clamping plate 1004 stably clamps the packaging can through the elastic force of the return spring 1003, and then moves it to the bottom of the quantitative hopper 807 through the rotation of the transmission belt on the surface of the conveyor 9, so as to realize the filling of calcium carbonate granules; a PLC controller 11 is installed on one side of the surface of the support base 1 for automatic control of various electrical components in the device. The bottom sides of the support base 1 are fixedly connected to the conveyor 9, and the bottom of the conveyor 9 is rotatably mounted with casters 12. Through the movement support of the casters 12, the entire equipment can be moved easily.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In actual use, a certain amount of compound calcium carbonate granules to be filled is added to hopper 4. Under the action of gravity, the material enters the conveying cylinder 2 through discharge pipe 3. The drive motor 6 is started, and its output end drives the drive shaft 7 to rotate inside the conveying cylinder 2. The two sets of spiral conveying blades 801 symmetrically mounted on the drive shaft 7 rotate synchronously, realizing bidirectional material pushing. Simultaneously with the rotation of the drive shaft 7, the driving bevel gear 802 connected in its middle rotates, driving the driven bevel gear 804 and the connected stirring rod 803 to rotate synchronously inside hopper 4 and discharge pipe 3 through gear meshing. The rotation of the stirring rod 803 effectively prevents blockage of discharge pipe 3. When the material is conveyed by the spiral conveying blades... After the sheet 801 is pushed to both ends of the conveying cylinder 2, it falls into the weighing cylinder 809 in the corresponding quantitative hopper 807 through the discharge pipes 805 set on both sides of the bottom. The pressure sensor 810 at the bottom of the weighing cylinder 809 can detect the mass of the falling material in real time. When the pressure sensor 810 detects that the mass of the falling material reaches the preset single filling dose, the PLC controller 11 immediately issues a command to start the drive motor 808, which drives the weighing cylinder 809 to rotate downward to discharge the material. Before the weighing cylinder 809 rotates, the PLC controller... Device 11 first controls the extension of the electric telescopic rod 811, which pushes the baffle plate 812 to move quickly to the outlet of the discharge pipe 805, temporarily closing the discharge pipe 805 to prevent material from continuing to fall during the rotation of the weighing cylinder 809, thus ensuring measurement accuracy. After the weighing cylinder 809 finishes discharging, the electric telescopic rod 811 resets, the baffle plate 812 retracts, and the discharge pipe 805 reopens to continue the next cycle of material conveying and weighing. Simultaneously, the conveyor 9 runs smoothly under the drive of the servo motor, and its conveyor belt... The positioning rod 1001 on the surface drives the carrier box 1002 to move sequentially. The operator or automatic feeding device presses the empty calcium carbonate granule packaging can into the carrier box 1002. The can body presses the clamping plate 1004 to compress the return spring 1003. Under the action of the spring force, the clamping plate 1004 achieves adaptive clamping of the outer wall of the packaging can. When the carrier box 1002 moves with the conveyor belt to directly below the quantitative hopper 807, the equipment automatically triggers the filling action: the weighing cylinder 809 completes the rotation and discharge, and the precisely dosed granules fall into the packaging can below. Subsequently, the filled medicine can is moved out of the filling station by the conveyor 9 and removed, and enters the subsequent sealing or inspection process.

[0033] 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.
