Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production and processing technology, specifically to a compound calcium carbonate granule filling and sealing device. Background Technology

[0002] Compound calcium carbonate granules, a common calcium supplement, are widely used in clinical practice and daily health care. During the production process, the filling and sealing of the granules are crucial steps in ensuring the quality, efficacy, and safety of the drug. Currently, semi-automatic or fully automatic packaging equipment is mostly used for filling and sealing these granules, first filling a predetermined amount of granules into the packaging bag, and then sealing the bag.

[0003] However, existing filling and sealing devices still have many shortcomings in practical applications. To ensure filling accuracy, existing equipment usually requires an additional online weighing system to weigh the materials one by one before filling, achieving precise control through feedback adjustment. However, this weighing-before-filling mode not only increases the complexity of the equipment but also requires setting up independent weighing stations, conveying mechanisms, and rejection devices, resulting in a complex overall structure, increased failure rate, and a prolonged single filling cycle, seriously affecting production pace and reducing overall filling efficiency. In addition, precision components such as weighing sensors are expensive and require regular calibration and maintenance, further increasing equipment investment and operating costs. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a compound calcium carbonate granule filling and sealing 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 filling and sealing device includes a support frame, a feeding cylinder mounted on the top of the support frame, a gear ring rotatably mounted on the top of the feeding cylinder, a spiral conveying blade mounted at the center of the gear ring, a discharge pipe connected to the bottom of the feeding cylinder, a quantitative discharge mechanism between the discharge pipe and the feeding cylinder, a positioning frame connected to one side of the support frame, a take-up roller rotatably connected to one side of the positioning frame, a limiting hopper mounted at the bottom of the take-up roller, a limiting ring mounted at the bottom of the limiting hopper, and an automatic sealing mechanism between the positioning frame and the support frame.

[0007] Furthermore, in order to achieve quantitative discharge of the discharge pipe during filling, the quantitative discharge mechanism includes a drive shaft connected to the end of the spiral conveyor blades, a baffle plate is rotatably installed on the surface of the drive shaft, the interior of the discharge pipe is divided by the baffle plate to form multiple discharge channels, and adjusting plates are connected to both sides of the drive shaft. The surface of the adjusting plates has discharge holes that cooperate with the discharge channels.

[0008] Furthermore, in order to realize the rotation of the spiral conveyor blades and the drive shaft, a drive motor is installed on one side of the surface of the feed cylinder. The output end of the drive motor is connected to a drive gear, which meshes with a gear ring.

[0009] Furthermore, in order to achieve heat sealing connection on both sides of the compound calcium carbonate granule packaging bag, a support rod is installed on one side of the inner wall of the limiting hopper, and heat sealing rollers are rotatably installed at the end of the support rod and on the bottom side of the limiting hopper.

[0010] Furthermore, in order to seal and cut the filled packaging bag, the automatic sealing mechanism includes an electric push rod installed on one side of the positioning frame, a transmission frame connected to the end of the electric push rod, heat sealing blocks installed on one side of the surface of the transmission frame and the positioning frame respectively, a cutting blade installed on one side of the transmission frame, and a cutting groove opened on one side of the surface of the positioning frame.

[0011] Furthermore, in order to continuously drive the packaging bag for filling compound calcium carbonate granules downwards, a second drive motor is installed on one side of the positioning frame, and conveying rollers are installed on the output end of the second drive motor and on one side of the surface of the positioning frame.

[0012] Furthermore, in order to achieve automated control of the various electrical components within the device, a PLC controller is installed on one side of the surface of the feeding cylinder.

[0013] The beneficial effects of this utility model are as follows: By setting an efficient and stable quantitative discharge mechanism between the feeding cylinder and the discharge pipe, the precise measurement and mechanized continuous discharge of compound calcium carbonate granules are realized. There is no need to configure an additional online weighing sensor or independent weighing platform, which simplifies the equipment configuration and reduces the procurement and maintenance costs. Moreover, the quantitative discharge mechanism enables the material to flow smoothly and respond quickly from feeding to quantitative discharge, and can realize high-frequency and periodic precise discharge, which significantly improves the single filling speed and avoids the waiting time caused by "weighing first and then filling" in the traditional process, thus greatly improving the overall production efficiency.

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.

[0026] According to an embodiment of the present invention, a compound calcium carbonate granule filling and sealing device is provided.

[0027] like Figures 1-3 As shown, a compound calcium carbonate granule filling and sealing device according to an embodiment of the present invention includes a metal support frame 1 for stable support of the entire device; a feeding cylinder 2 is installed on the top of the support frame 1, which can hold more compound calcium carbonate granules during filling; a gear ring 3 is rotatably installed on the top of the feeding cylinder 2, and a spiral conveying blade 4 is installed at the center of the gear ring 3, which can prevent calcium carbonate granules from accumulating and clogging inside the feeding cylinder 2 by rotating the spiral conveying blade 4; a discharge pipe 5 is connected to the bottom of the feeding cylinder 2, and a quantitative discharge mechanism 6 is provided between the discharge pipe 5 and the feeding cylinder 2. The support frame 1 is used to achieve single-quantity dispensing during filling; a positioning frame 7 is connected to one side of the support frame 1, and a winding roller 8 is rotatably connected to one side of the positioning frame 7 for placing the plastic film for the compound calcium carbonate granule packaging bag; a limiting hopper 9 is installed at the bottom of the winding roller 8, and by passing the plastic film through the limiting hopper 9, the plastic film can be bent along the limiting hopper 9 to initially form a calcium carbonate packaging bag with open ends; a limiting ring 10 is installed at the bottom of the limiting hopper 9 to limit the movement of the initially formed packaging bag; an automatic sealing mechanism 11 is provided between the positioning frame 7 and the support frame 1 for sealing and cutting the packaging bag after filling with calcium carbonate granules.

[0028] like Figures 1-5 As shown, the quantitative discharge mechanism 6 includes a drive shaft 601 connected to the end of the screw conveyor blades 4. A baffle plate 602 is rotatably mounted on the surface of the drive shaft 601. The baffle plate 602 is connected to the inner wall of the discharge pipe 5. The interior of the discharge pipe 5 is divided by the baffle plate 602 to form multiple discharge channels 603. There are four discharge channels 603. A pair of adjusting plates 604 are connected to both sides of the drive shaft 601. The surface of the adjusting plates 604 has discharge holes 605. The size and shape of the discharge holes 605 match the discharge channels 603. The discharge holes 605 on the surfaces of the two adjusting plates 604 on the drive shaft 601 are staggered by a 90-degree angle, which enables material discharge. Alternating feeding and discharging at both ends of pipe 5; a drive motor 606 is installed on one side of the surface of the upper feeding cylinder 2, and the output end of the drive motor 606 is connected to the drive gear 607. The drive gear 607 meshes with the gear ring 3. The drive motor 606 drives the drive gear 607 to rotate, so that the drive gear 607 can drive the gear ring 3 to rotate at the top of the upper feeding cylinder 2. In turn, the gear ring 3 drives the spiral conveying blade 4 and the drive shaft 601 to rotate in the upper feeding cylinder 2 and the discharge pipe 5 respectively. At this time, the compound calcium carbonate particles in the upper feeding cylinder 2 can enter the various discharge channels 603 in the discharge pipe 5 respectively, and be discharged through the discharge hole 605, realizing the overall quantitative discharge of the device.

[0029] like Figures 1-8 As shown, a support rod 12 is installed on one side of the inner wall of the limiting hopper 9. Heat-sealing rollers 13 are rotatably installed at the end of the support rod 12 and on the bottom side of the limiting hopper 9. The two heat-sealing rollers 13 are oriented in opposite directions and are both made of electrothermal material, enabling heat sealing of both sides of the plastic film of the packaging bag moving along the limiting hopper 9. The automatic sealing mechanism 11 includes an electric push rod 1101 installed on one side of the positioning frame 7. A transmission frame 1102 is connected to the end of the electric push rod 1101. Heat-sealing blocks 1103 are installed on one side of the transmission frame 1102 and the surface of the positioning frame 7, respectively. The heat-sealing blocks 1103 are made of electrothermal material. A cutting blade 1104 is installed on one side of the transmission frame 1102. A cutting groove 1105 is opened on one side of the surface of the positioning frame 7. A second transmission motor 1106 is installed on one side of the positioning frame 7. The output end of the second transmission motor 1106 is connected to the positioning frame 7. One side of the frame 7 is equipped with conveyor rollers 1107. The conveyor rollers 1107 are rotated by the drive motor 1106. The plastic film of the packaging bag, which has been limited and formed by the limiting bucket 9 and the limiting ring 10, is placed between the two conveyor rollers 1107. The rotation of the conveyor rollers 1107 causes the plastic film of the packaging bag to move downward continuously. During the movement, the electric push rod 1101 intermittently extends and retracts, driving the two heat sealing blocks 1103 to perform transverse heat sealing on the plastic film of the packaging bag. After heat sealing, the quantitative discharging mechanism 6 fills it with calcium carbonate granules. After filling, it moves downward and moves into the cutting groove 1105 through the cutting blade 1104 to cut the heat-sealed area, thereby completing the filling and sealing of compound calcium carbonate granules. A PLC controller 14 is installed on one side of the surface of the feeding cylinder 2 to control the various electrical components in the device.

[0030] 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.

[0031] In actual use, the compound calcium carbonate granules that need to be filled and sealed are placed into the feeding cylinder 2. The PLC controller 14 starts the drive motor 606, drive motor 1106, and electric push rod 1101, and controls the electric push rod 1101 to extend and retract at fixed intervals. The plastic film of the packaging bag on the winding roller 8 passes through the limiting hopper 9 and bends along the limiting hopper 9. The two heat-sealing rollers 13 in the limiting hopper 9 can heat-seal the two sides of the plastic film of the packaging bag moving along the limiting hopper 9, initially forming a calcium carbonate packaging bag with open ends. Then, the preliminarily heat-sealed plastic film of the packaging bag is placed between the two conveying rollers 1107, and the conveying rollers 1107... The rotation continuously drives the plastic film of the packaging bag downwards; after the drive motor 606 starts, it can drive the drive gear 607 to rotate, so that the drive gear 607 can drive the gear ring 3 to rotate at the top of the feeding cylinder 2, and then the gear ring 3 drives the spiral conveying blade 4 and the drive shaft 601 to rotate in the feeding cylinder 2 and the discharge pipe 5 respectively. At this time, the compound calcium carbonate granules in the feeding cylinder 2 can enter the various discharge channels 603 in the discharge pipe 5 respectively, and be discharged through the discharge hole 605. When the drive shaft 601 rotates, the two adjusting plates 604 on its surface can rotate at both ends of the discharge pipe 5 respectively, so that the discharge hole 605 on the adjusting plate 604 is connected to the discharge channel in the discharge pipe 5. The two ends of channel 603 work alternately. Because the discharge holes 605 on the surfaces of the two adjusting plates 604 are staggered at a 90-degree angle, the two discharge channels 603 with one open end in the discharge pipe 5 are not adjacent, and the other two discharge channels 603 are closed by the adjusting plates 604. At this time, the top-opening discharge channel 603 continuously stores calcium carbonate particles falling from the feeding cylinder 2, while the bottom-opening discharge channel 603 discharges its contents into the packaging bag. The stored and discharged materials are the same and quantitative. Therefore, as the drive shaft 601 drives the adjusting plates 604 to rotate, the different discharge channels 603 in the discharge pipe 5 can respectively feed and discharge materials. When a certain amount of calcium carbonate granules are discharged from one of the bottom-opening discharge channels 603, the other top-opening discharge channel 603 can collect the calcium carbonate granules, so that a certain amount of calcium carbonate granules can be discharged from the discharge pipe 5 each time. During the movement of the plastic film of the packaging bag, the intermittent extension and retraction of the electric push rod 1101 can drive the two heat-sealing blocks 1103 to perform lateral heat sealing on the plastic film of the packaging bag. After heat sealing, the quantitative discharge mechanism 6 fills it with calcium carbonate granules. After filling, the plastic film of the packaging bag moves downward and moves into the cutting groove 1105 through the cutting blade 1104 to cut the heat-sealed area, thereby completing the filling and sealing of compound calcium carbonate granules.

[0032] 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.
