Technical Field

[0001] This utility model relates to the technical field of mineral powder packaging, and in particular to a dolomite powder packaging feeding device. Background Technology

[0002] In the process of mining and processing dolomite, a crusher is used to pulverize the dolomite into mineral powder. The powder is then transported by a conveyor belt or screw conveyor, and finally bagged through the outlet of a storage tank for convenient use and transportation. However, the aforementioned equipment lacks a mechanism to secure the bags during the bagging process, requiring prolonged manual support of the bag openings, increasing labor costs. Furthermore, gaps exist between the bag opening and the outer wall of the outlet, allowing dolomite powder to escape and pollute the surrounding environment, thus reducing the equipment's effectiveness. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a dolomite powder packaging and feeding device. By using two arc-shaped plates to press the opening of the packaging bag against the outer wall of the discharge pipe, it can not only fix the packaging bag, but also reduce the leakage of dolomite powder from the bag opening.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The elastic member is disposed between the limiting member and the vertical plate, and the driving assembly is used to drive the mounting rod to move horizontally closer to the discharge pipe.

[0008] Furthermore, the elastic element is a helical spring, which is movably sleeved on the outside of the mounting rod, and the limiting element is a nut threadedly connected to the mounting rod.

[0009] Furthermore, a first wedge block is provided at the other end of the mounting rod, the driving component is a cylinder, and a second wedge block is connected to the telescopic end of the cylinder. The second wedge block cooperates with the first wedge block. When the second wedge block moves downward, the first wedge block moves horizontally toward one side of the vertical plate.

[0024] See Figures 1 to 2A dolomite powder packaging and feeding device includes: a storage tank 100, a discharge pipe 110 connected to the lower end of the storage tank 100, an mounting frame 120 provided on the upper part of the discharge pipe 110, two arc-shaped plates 130 movably provided on the mounting frame 120, the two arc-shaped plates 130 together surround the lower end of the discharge pipe 110, there is a gap space between the arc-shaped plates 130 and the outer wall of the discharge pipe 110 for accommodating packaging bags, an elastic element 140 is provided between the arc-shaped plates 130 and the mounting frame 120, and a driving component is correspondingly connected to each arc-shaped plate 130, the driving component is used to drive the arc-shaped plate 130 to press the packaging bag against the outer wall of the discharge pipe 110.

[0025] In use, the dolomite powder packaging and feeding device with the above structure places the bag opening in the gap space, and then the drive component drives the arc plate 130 to move towards the side closer to the discharge pipe 110. Finally, the two arc plates 130 press the bag against the outer wall of the discharge pipe 110. This not only fixes the bag and reduces the labor burden, but also helps to reduce the gap between the bag opening and the discharge pipe 110, thereby preventing the dolomite powder from escaping from the bag opening during the falling process, which helps to improve the bagging effect of dolomite powder.

[0026] Understandably, the diameter of the arc plate 130 is slightly larger than the diameter of the discharge pipe 110, which helps the concave surface of the arc plate 130 to match the contour of the outer wall of the discharge pipe 110, so that the two arc plates 130 can work together to tighten the bag opening of the packaging bag, thereby reducing the gap between the bag opening of the packaging bag and the outer wall of the discharge pipe 110.

[0027] See Figures 1 to 2 Furthermore, the mounting frame 120 includes a vertical plate 121, and a mounting rod 131 is movably disposed on the lower part of the vertical plate 121. One end of the mounting rod 131 is connected to an arc-shaped plate 130, and the other end of the mounting rod 131 is threadedly connected to a limiting member. An elastic member 140 is disposed between the limiting member and the vertical plate 121. A driving assembly is used to drive the mounting rod 131 to move horizontally closer to the discharge pipe 110. Specifically, when it is necessary to fix the packaging bag, the driving assembly drives the mounting rod 131 to move towards the side closer to the discharge pipe 110, so that the arc-shaped plate 130 and the discharge pipe 110 together clamp the packaging bag, while the limiting member drives the elastic member 140 to be in a compressed state. When the driving assembly resets, the elastic member 140 restores its deformation to move the arc-shaped plate 130 away from the discharge pipe 110, thereby facilitating the removal of the packaging bag from the discharge pipe 110.

[0028] See Figures 1 to 2Furthermore, the elastic element 140 is a helical spring, which is movably sleeved on the outside of the mounting rod 131, and the limiting element is a nut 132 threadedly connected to the mounting rod 131. Specifically, the helical spring helps to increase the elastic potential energy stored in the elastic element 140 under compression, thereby increasing the elastic force driving the arc plate 130 to return to its original position. The nut 132 allows for adjustment of the elastic deformation range of the elastic element 140 by adjusting its position. It is understood that the mounting rod 131 has a smooth section and a threaded section, and the vertical plate 121 has a through hole that mates with the smooth section, thereby using the engagement of the through hole and the smooth section to guide and limit the movement of the mounting rod 131.

[0029] See Figures 1 to 2 Furthermore, a first wedge block 150 is provided at the other end of the mounting rod 131. The driving assembly is a cylinder 200, and a second wedge block 210 is connected to the telescopic end of the cylinder 200. The second wedge block 210 and the first wedge block 150 cooperate with each other. When the second wedge block 210 moves downward, the first wedge block 150 moves horizontally toward one side of the vertical plate 121. Specifically, the first wedge block 150 has an inclined surface that is inclined downward toward the side away from the mounting rod 131, while the second wedge block 210 has a mating surface parallel to the inclined surface. When the cylinder 200 drives the second wedge block 210 to move downward, the mating surface of the second wedge block 210 cooperates with the inclined surface of the first wedge block 150, thereby generating a dispersing force that drives the first wedge block 150 to move toward the side closer to the discharge pipe 110. When cylinder 200 drives the second wedge block 210 upward, the elastic element 140 restores its deformation to drive the first wedge block 150 to move away from the discharge pipe 110, ensuring that the first wedge block 150 remains in contact with the second wedge block 210. The arrangement of the first wedge block 150 and the second wedge block 210 not only transmits the driving force of cylinder 200 but also allows for a change in the installation position of the drive mechanism, simplifying its installation. It is understood that cylinder 200 can also be replaced with a hydraulic cylinder as needed, which will not be detailed here.

[0030] See Figures 1 to 2 Furthermore, the mounting frame 120 includes a flat plate 122 connected to the discharge pipe 110. The flat plate 122 is connected above the vertical plate 121, and two hooks 123 are arranged opposite each other on the flat plate 122. The hooks 123 are located above the mounting rod 131. Specifically, when installing the packaging bag, the handle of the packaging bag is hung on the hook 123, which can pre-fix the packaging bag and facilitate the subsequent tightening of the bag opening by the two curved plates 130.

[0031] See Figures 1 to 2Furthermore, the flat plate 122 has a waist-shaped hole 124 along the horizontal direction, and the hook 123 has a mounting hole. The waist-shaped hole 124 and the mounting hole are connected by a bolt assembly. Specifically, the bolt assembly includes a bolt shank and a locking nut, with the lower end of the bolt shank connected to the hook 123. In use, the height of the hook 123 on the flat plate 122 can be changed by adjusting the height of the locking nut on the bolt shank. In addition, the waist-shaped hole 124 facilitates changing the horizontal position of the hook 123, making it easy to adapt to the size of the bag opening of different packaging bags.

[0032] See Figures 1 to 2 Furthermore, a reinforcing rib 125 is inclinedly connected between the vertical plate 121 and the flat plate 122, which helps to strengthen the connection between the vertical plate 121 and the flat plate 122, thereby improving the structural strength of the mounting bracket 120. It is understood that the reinforcing rib 125 is fixed between the vertical plate 121 and the flat plate 122 by welding.

[0033] Furthermore, the arc plate 130 is provided with an elastic layer facing the outer wall of the discharge pipe 110, so that the elastic layer can wrap around the opening of the packaging bag, which also helps to reduce the rigid collision between the arc plate 130 and the discharge pipe 110.

[0034] See Figures 1 to 2 Furthermore, a conical cylinder 101 connects the storage tank 100 and the discharge pipe 110. The small end of the conical cylinder 101 is connected to the discharge pipe 110, thereby utilizing the conical cavity formed by the conical cylinder 101 to collect and guide the material, which helps to accelerate the output efficiency of the material. It can be understood that the lower end of the storage tank 100 has four support rods 102 distributed in a rectangular shape, and the lower part of the four support rods 102 is connected to a horizontal plate 103, which facilitates the placement of packaging bags on top of the horizontal plate 103 for bagging.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
