Description

A dust-free powder packaging equipment Technical Field

[0001] This utility model relates to the field of powder packaging technology, specifically to a dust-free powder packaging equipment. Background Technology

[0002] In order to prevent powder from spilling out during the packaging process, the bag is usually moved to the conveying pipe by the conveying mechanism and the external bag opening mechanism, and then the powder is filled into the packaging bag by the cooperation of the closed conveying device and the discharge pipe.

[0003] For example, Chinese patent CN221542032U discloses an automatic powder packaging machine. This packaging machine uses spiral blades to move the powder downwards into the packaging bag. The weight of the packaging bag is detected by a weight component, and the feeding is automatically stopped after the appropriate weight is reached.

[0004] However, when the device delivers the powder into the packaging bag, there may be powder flying around; at the same time, the packaging bag after filling is irregularly shaped, which is not convenient for subsequent transportation and storage.

[0005] Based on this, the present invention designs a dust-free powder packaging equipment to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dust-free powder packaging equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dust-free powder packaging device includes a mounting frame, a bag opening module, a shaping module, a feeding mechanism, and a conveying mechanism for conveying the bags.

[0009] The mounting frame is equipped with a bag opening module that works with the conveying mechanism to open the bag opening; a feeding mechanism is installed on the upper side of the mounting frame; a shaping module for shaping the bag is provided between the mounting frame and the conveying mechanism; the shaping module is connected to the mounting frame.

[0010] The feeding mechanism includes a guiding module, a feeding module, and a blocking module. The guiding module is installed on the mounting frame, the feeding module is installed on the upper side of the guiding module, and the blocking modules are symmetrically installed on the lower side of the guiding module.

[0011] Furthermore, the bag opening module includes a clearance module and an adsorption module, with the clearance module mounted on the mounting frame and the adsorption module mounted on the clearance module.

[0012] Furthermore, the shaping module includes a synchronous drive component and a shaping component, the synchronous drive component is mounted on a mounting bracket, and the shaping component and the synchronous drive component are connected.

[0013] Furthermore, the shaping component includes a base, sliding rods, L-shaped movable plates, and a support platform. Sliding rods are symmetrically fixedly installed on the left and right sides of the base; L-shaped movable plates are symmetrically arranged at the front and back of the base, and the bottom of the L-shaped movable plates is slidably connected to the two sliding rods for limiting; a support platform is fixedly installed in the middle of the base.

[0014] Furthermore, the material guiding module includes a telescopic material guiding assembly and a concealed drive assembly. The telescopic material guiding assembly is mounted on the mounting frame, and the concealed drive assembly is installed inside the telescopic material guiding assembly.

[0015] Furthermore, the telescopic material guide assembly includes a fixed box, a movable box, a discharge box, and corrugated pipes. The fixed box is fixedly mounted on the mounting frame, the movable box is located below the fixed box, and the discharge box is located below the movable box. The upper end of one set of corrugated pipes is fixedly connected to the bottom of the fixed box, and its lower end is fixedly connected to the upper end of the movable box. The upper end of another set of corrugated pipes is fixedly connected to the bottom of the movable box, and its lower end is fixedly connected to the upper end of the discharge box. The fixed box, movable box, discharge box, and corrugated pipes are provided with a discharge trough and an exhaust trough that communicate with the discharge module in the middle.

[0016] Furthermore, the concealed drive assembly includes a feeding cylinder and a guide rod.

The feeding cylinder is fixedly installed in the fixed box, and the output end of the feeding cylinder is fixedly connected to the feeding box. The guide rod is fixedly installed on the upper side of the feeding box, and the guide rod is slidably connected to the fixed box and the movable box.

[0017] Furthermore, the shown material blocking module includes a material blocking hopper and a rotating rod. The material blocking hopper is hinged to the material feeding box, and a torsion spring is sleeved on the hinge shaft between the material blocking hopper and the material feeding box. The two elastic legs of the torsion spring abut against the material blocking hopper and the material feeding box respectively. One end of the rotating rod is rotatably connected to the material blocking hopper, and the other end of the rotating rod is rotatably connected to the movable box.

[0018] Compared with the prior art, the advantages of this utility model are as follows: The conveying mechanism moves the bag to the middle of the shaping module. The bag opening module, in conjunction with the conveying mechanism, opens the bag opening, aligning it with the guiding module. The guiding module extends downward into the bag opening, at which point the blocking module automatically opens, no longer obstructing the bottom of the guiding module. Thus, before the guiding module extends into the bag, its bottom is blocked by the blocking module, preventing powder remaining in the feeding module and guiding module from falling to the outside. This prevents powder from flying during the bagging process. The feeding module then conveys the powder into the bag through the guiding module. The shaping module positions the two sides of the bag. During this process, the bag moves continuously through the cooperation of the conveying mechanism and the bag opening module, achieving continuous bagging of powder. The cooperation of the guiding module, feeding module, and blocking module ensures that the bag has a regular shape after being filled with powder, facilitating subsequent conveying.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
