It also eliminates the need for manual hand-holding to open the bag, effectively reducing labor intensity.

Description

Technical Field

[0001] This utility model relates to the technical field of calcium carbonate processing equipment, specifically to a calcium carbonate powder packaging device. Background Technology

[0002] Heavy calcium carbonate is an important food additive. It is made by grinding natural carbonate minerals such as calcite, marble, and limestone. The ground product is usually temporarily stored in a container. When packaging and repackaging, a packaging machine is usually needed to quantitatively fill the packaging bags. Existing packaging machines require manual support to open the bag opening and align it with the machine's discharge port. When filling the bag with calcium carbonate powder, because the bag opening is not sealed to the outside, the air trapped inside the packaging bag forms a backflow when the powder falls, causing the powder to escape from the bag opening and leak to the outside, polluting the workshop environment and endangering the health of the workers. Utility Model Content

[0003] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a calcium carbonate powder packaging device.

[0004] To achieve the above objectives, the present invention proposes a calcium carbonate powder packaging device, comprising a frame and a material hopper mounted on the frame. The top of the material hopper has a feed inlet, and the bottom of the material hopper has a discharge pipe. A bag opening mechanism is fitted onto the discharge pipe. The bag opening mechanism includes a support ring, a rotating ring, a transmission rod, and a sector plate. The support ring is slidably mounted on the discharge pipe. The rotating ring is rotatably mounted around the support ring. Several guide rails are radially fixed at the bottom of the rotating ring, and sliders are slidably mounted on the guide rails. The sector plate is fixed on the slider. One end of the transmission rod is hinged to the slider, and the other end of the transmission rod is hinged to the outer circumference of the support ring. The vertical height between adjacent guide rails is different, causing adjacent sector plates to be misaligned vertically.

[0005] To further optimize the technical solution, an internal gear ring is fixedly provided on the top of the rotating ring, a first motor is provided on the top surface of the support ring, a first gear is provided on the conveying end of the first motor, and the first gear meshes with the internal gear ring.

[0006] To further optimize the technical solution, L-shaped support rods are symmetrically arranged on both sides of the top surface of the support ring, and the L-shaped support rods are connected to the frame through lifting telescopic rods.

[0007] To further optimize the technical solution, a sealing plate is fixedly provided on the bottom surface of the support ring. The outer diameter of the sealing plate is the same as that of the rotating ring, and a gap is provided between the sealing plate and the rotating ring for the fan-shaped plate to be accommodated.

[0008] To further optimize the technical solution, a guide pipe is slidably sleeved between the support ring and the discharge pipe, and the guide pipe slides and rises and falls relative to the support ring.

[0009] To further optimize the technical solution, a rack is provided on the outer circumferential surface of the guide tube along the length direction, a second motor is provided on the support ring, and a second gear is provided at the output end of the second motor, which meshes with the rack.

[0010] To further optimize the technical solution, a sliding guide rod is provided on the outer circumferential surface of the guide tube along the length direction, and grooves are provided on the inner circumferential surfaces of the support ring and the sealing plate for the sliding guide rod and the rack to pass through.

[0011] To further optimize the technical solution, an anti-slip pad is provided on the outer periphery of the fan-shaped plate.

[0012] To further optimize the technical solution, the material hopper is equipped with a screw feeding mechanism, which includes screw blades, a rotating shaft, and a drive motor. The rotating shaft is vertically arranged on the axis of the material hopper, with its bottom end extending into the discharge pipe and its top end extending to the top surface of the material hopper. The drive motor is located on the top surface of the material hopper, and its conveying end is connected to the top end of the rotating shaft. The screw blades are fixedly arranged on the shaft section of the rotating shaft located inside the discharge pipe.

[0013] To further optimize the technical solution, a bagging support mechanism is provided below the material barrel. The bagging support mechanism includes a positioning ring and several support rods, with the top ends of the support rods fixedly connected to the positioning ring.

[0014] The beneficial effects of this utility model include: when the rotating support ring rotates clockwise, the transmission rod can push the slider to move radially outward on the guide rail, thereby driving the sector plates to move outward synchronously and unfold. After all the sector plates unfold, they form a circle that opens and seals the opening of the packaging bag, preventing the powder from overflowing and leaking when calcium carbonate powder is poured into the packaging bag, thus avoiding pollution of the workshop environment; by adjusting the rotation angle of the rotating ring, the outer diameter of the circle formed by the sector plates can be adjusted to adapt to the opening diameter of different packaging bags; when packaging calcium carbonate powder, this utility model eliminates the need for manual hand-holding to open the bag opening, effectively reducing labor intensity and preventing manual inhalation of powder, which could affect health.

[0026] Please see Figures 1 to 6 One embodiment of the calcium carbonate powder packaging device includes a frame 1 and a material hopper 2 mounted on the frame 1. The bottom of the material hopper 2 is conical, and an inlet 201 is provided at the top of the material hopper 2. A discharge pipe 202 is vertically provided at the bottom of the material hopper 2. A bag opening mechanism 3 is fitted onto the discharge pipe 202. The bag opening mechanism 3 is used to open the bag opening of the packaging bag. The bag opening mechanism 3 includes a support ring 301, a rotating ring 302, a transmission rod 303, and a sector plate 304. The support ring 301 is slidably fitted onto the discharge pipe 202, and the rotating ring 302 is rotatably fitted around the support ring 301. The bottom of the bag is fixed with several guide rails 305 radially arranged. A slider 306 slides on the guide rails 305, and a sector plate 304 is fixed on the slider 306. One end of the transmission rod 303 is hinged to the slider 306, and the other end is hinged to the outer circumference of the support ring 301. The vertical height between adjacent guide rails 305 is different, causing adjacent sector plates 304 to be staggered vertically. When unfolded, they combine to form an approximately circular structure. The outer circumference of the circular structure can tightly fit the bag opening, reducing dust leakage gaps. This is suitable for easily deformable packaging materials such as woven bags, and adjacent sector plates 304 will not interfere with each other when stored. Specifically, the rotating ring 302 and the support ring 301 are coaxially arranged, and the rotating ring 302 can rotate around the support ring 301. The transmission rod 303 has an arc-shaped structure. In this embodiment, when the rotating ring 302 rotates clockwise around the support ring 301, the transmission rod 303 can push the slider 306 to move radially outward on the guide rail 305, thereby driving the sector plates 304 to move outward and unfold synchronously. After all the sector plates 304 unfold, they open the bag opening of the packaging bag to form a circle and seal it, preventing the powder from overflowing and causing leakage when calcium carbonate powder is injected into the packaging bag, thus avoiding pollution of the workshop environment. Moreover, by adjusting the rotation angle of the rotating ring 302, the outer diameter of the circle formed by the sector plates 304 can be adjusted to adapt to the opening diameter of different packaging bags. After filling, the rotating ring 302 reverses, and the transmission rod 303 synchronously pulls all the sector plates 304 back inward, thus opening the bag. When packaging calcium carbonate powder, there is no need for manual hand support to open the bag opening, which effectively reduces labor intensity and reduces the risk of manual inhalation of powder, thus protecting health.

[0027] In a specific example, an internal gear ring 3021 is fixedly mounted on the top of the rotating ring 302, and a first motor 3011 is fixedly mounted on the top surface of the support ring 301. A first gear 3012 is mounted on the conveying end of the first motor 3011, and the first gear 3012 meshes with the internal gear ring 3021. The first motor 3011 drives the first gear 3012 to rotate the internal gear ring 3021 (rotating ring 302), thus achieving the forward and reverse rotation of the rotating ring 302, and consequently, the unfolding or retraction of the sector plate 304.

[0028] In a specific example, L-shaped support rods 3013 are symmetrically arranged on both sides of the top surface of the support ring 301. The L-shaped support rods 3013 are connected to the frame 1 through the lifting telescopic rod 4. The lifting telescopic rod 4 is pneumatically, electrically, or hydraulically driven. The lifting telescopic rod 4 drives the entire bag opening mechanism 3 to rise and fall into the bag opening to open the bag opening, or to retract from the bag opening position.

[0029] In a preferred embodiment, a sealing plate 307 is fixedly provided on the bottom surface of the support ring 301. The outer diameter of the sealing plate 307 is the same as that of the rotating ring 302, and a gap is provided between the sealing plate 307 and the rotating ring 302 for the fan-shaped plate 304 to be accommodated. By sealing the bottom of the support ring 301 and the rotating ring 302 with the sealing plate 307, it is prevented that the powder in the packaging bag will float upward and enter the guide rail 305 and the slider 306, thus affecting the movement of the slider 306. When the fan-shaped plate 304 retracts, it can be accommodated in the gap formed by the sealing plate 307 and the rotating ring 302, and when it unfolds outward, it extends out of the gap.

[0030] In a preferred embodiment, a guide pipe 308 is slidably sleeved between the support ring 301 and the discharge pipe 202. The guide pipe 308 can slide and rise relative to the support ring 301 and the discharge pipe 202. After the bag opening mechanism 3 opens and seals the bag opening, the guide pipe 308 slides down to the bottom of the packaging bag. When calcium carbonate powder is poured into the packaging bag, the powder enters the guide pipe 308 along the discharge pipe 202 and is injected into the packaging bag. During the pouring process, the guide pipe 308 gradually rises to reduce the falling height of the powder, reduce airflow disturbance, and prevent the powder from easily entraining air and forming a backflow airflow when falling, thereby reducing the amount of dust emission.

[0031] In a specific example, a rack 3081 is provided along the length of the outer circumference of the guide tube 308, and a second motor 3014 is provided on the support ring 301. A second gear 3015 is provided at the output end of the second motor 3014, and the second gear 3015 is meshed with the rack 3081. The second motor 3014 drives the second gear 3015 to move the rack 3081 up and down, thereby realizing the lifting and lowering of the guide tube 308.

[0032] In a preferred embodiment, a plurality of sliding guide rods 3082 are provided along the length of the outer peripheral surface of the guide tube 308, and grooves 309 are provided on the inner peripheral surfaces of the support ring 301 and the sealing plate 307 for the sliding guide rods 3082 and the rack 3081 to pass through. The guide tube 308 is held in the grooves 309 by the sliding guide rods 3082, preventing the guide tube 308 from rotating.

[0033] In a preferred embodiment, an anti-slip pad 3041 is provided on the outer peripheral surface of the sector plate 304. The anti-slip pad 3041 increases the friction between the sector plate 304 and the bag opening contact surface, preventing the bag opening from sliding or falling off during the filling process.

[0034] In a preferred embodiment, a screw feeding mechanism 5 is provided on the material hopper 2. The screw feeding mechanism 5 includes a screw blade 501, a rotating shaft 502, and a drive motor 503. The rotating shaft 502 is vertically arranged on the axis of the material hopper 2. The bottom end of the rotating shaft 502 extends into the discharge pipe 202, and the top end of the rotating shaft 502 extends to the top surface of the material hopper 2. The drive motor 503 is located on the top surface of the material hopper 2, and its conveying end is connected to the top end of the rotating shaft 502. The screw blade 501 is fixedly arranged on the shaft section of the rotating shaft 502 located inside the discharge pipe 202. Calcium carbonate powder is quantitatively fed and packaged through the vertically arranged screw feeding mechanism 5. The rotating shaft 502 is vertically arranged along the axis of the material hopper 2, and the screw blade 501 is located inside the discharge pipe 202. No additional horizontal conveying equipment is required, which can reduce the lateral footprint of the equipment.

[0035] In a preferred embodiment, a bagging support mechanism 6 is provided below the material hopper 2. The bagging support mechanism 6 includes a positioning ring 601 and several support rods 602, the top ends of which are fixedly connected to the positioning ring 601. Before filling, by placing the packaging bag inside the bagging support mechanism 6, the bag opening mechanism 3 extends into the bag opening, and the fan-shaped plate 304 opens the bag opening and presses against the inner wall of the positioning ring 601 to seal the bag opening, calcium carbonate powder can then be filled and packaged.
