Abstract
Description
Technical Field
[0001] This utility model relates to the field of quantitative packaging technology, specifically to an automatic quantitative packaging device. Background Technology
[0002] Packaging scales are general-purpose dust suppression packaging scales that use automated instruments to quickly weigh and quantitatively package materials. They are widely used in various packaging industries, including food, chemical raw materials, agricultural seeds, livestock feed, and daily necessities, due to their advantages such as fast weighing speed, high weighing accuracy, labor saving, simple operation, and convenient maintenance. Packaging scales typically consist of several parts, including an automatic weighing device, a conveying and unloading device, a bag clamping and sealing device, and a control device.
[0003] Existing packaging scales cannot simultaneously handle both small-sized packaging bags (hereinafter referred to as small bags) and large-sized packaging bags (hereinafter referred to as ton bags). When packaging small bags, a dedicated packaging scale for small bags is required. When packaging ton bags, an additional dedicated packaging scale for ton bags is needed. To address this, we propose an automatic quantitative packaging device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic quantitative packaging device. By installing a ton bag clamper and a small bag clamper on the same packaging device, a single packaging scale can be adapted to both ton packaging bags and small packaging bags, eliminating the need for an additional device, saving costs and reducing floor space. At the same time, the feeder is equipped with large and small spiral auger blades, which can realize fast and slow feeding, ensuring weighing accuracy.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Preferably, the buffer hopper consists of a hopper body and an end cover, and the working platform has a channel for the hopper body to be placed in, and the end cover of the buffer hopper is installed on the plane of the working platform.
[0008] Preferably, the feeder is equipped with large and small spiral auger blades.
[0009] Preferably, the discharge port of the inner hopper is cylindrical, and a dust cover is fitted onto the outer contour of the cylindrical shape, and a dust removal system is connected to the outside of the dust cover.
[0010] Preferably, the feeding channel is connected to the weighing frame through several evenly distributed crossbars, and each crossbar is equipped with a hook on the weighing frame.
[0011] Preferably, the feeding channel is a hollow cylinder and is divided into an upper part and a lower part, the upper part being cylindrical and the lower part being conical.
[0012] This invention provides an automatic quantitative packaging device. It has the following beneficial effects:
[0013] By installing both ton bag clamps and small bag clamps on the same packaging device, a single packaging scale can be adapted to both ton packaging bags and small packaging bag requirements, eliminating the need for an additional device, saving costs and reducing floor space.

[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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] See attached document Figures 1-3 An automatic quantitative packaging device includes a frame on which a working platform 1 is installed. The working platform is made of steel and is used to support the equipment. It is also equipped with guardrails and ladders for easy maintenance in the future.
[0029] A buffer silo 2 is installed on the working platform 1. The body of the buffer silo 2 is funnel-shaped. Specifically, the buffer silo 2 is divided into a body and an end cover. The working platform 1 has a channel for the body to be inserted. The end cover of the buffer silo 2 is installed on the plane of the working platform.
[0030] The bottom of the buffer silo 2 is equipped with a feeder 3, which is connected to the discharge port of the silo body. The material at the bottom of the silo body will fall into the feeder 3 and be fed by the feeder 3. The feeder 3 is equipped with large and small spiral auger blades. The large spiral auger blade can be used for rapid feeding, while the small spiral auger blade can be used for slow feeding to ensure weighing accuracy.
[0031] The buffer hopper 2 can temporarily store 1m³ of material, ensuring that the feeder 3 has a stable material source.
[0032] The feeder 3 is connected to an inner hopper 4 at its outlet. A flap door is installed inside the inner hopper 4, and a controller is installed outside the inner hopper 4 to control the opening and closing of the flap door, ensuring that the material flow can be quickly cut off and preventing material leakage.
[0033] The discharge port of the inner hopper 4 is cylindrical, and a dust cover 5 is fitted onto the outer contour of the cylindrical shape. A dust removal system is connected to the outside of the dust cover 5 to prevent dust from leaking directly and drifting into the air, thus avoiding safety hazards.
[0034] A weighing frame 8 is installed at the bottom of the frame. A material feeding channel is installed in the middle of the weighing frame 8, which corresponds to the discharge port of the inner hopper 4. The material feeding channel is hollow cylindrical and is divided into an upper part and a lower part. The upper part is cylindrical and the lower part is conical. A ton bag clamp 6 is installed on the outside of the upper part of the material feeding channel, which can clamp the bag mouth of the ton bag packaging bag to ensure that the material enters the bag.
[0035] The feeding channel is connected to the weighing frame 8 by several evenly distributed crossbars, and each crossbar is equipped with a hook on the weighing frame 8, which can hold the lifting strap of the ton bag packaging bag. Through the ton bag clamp 6 and the hooks, the stability of the ton bag packaging bag can be maintained during the material filling process, ensuring that the material flows smoothly into the bag.
[0036] An auxiliary frame is also installed on the weighing frame 8, and a small bag clamp 7 is installed on the auxiliary frame. The small bag clamp 7 is installed in the lower half of the material feeding channel. The small bag clamp 7 can clamp the bag opening of the small package bag to ensure that the material enters the package bag. In some embodiments, in order to adapt to various sizes of package bags, a lifting cylinder is also configured between the auxiliary frame and the small bag clamp 7. A weighbridge 9 is installed at the bottom of the weighing frame 8.
[0037] When packaging ton bags, remove the small bag clamp 7, hang the bag straps on the hooks on the weighing frame 8, and clamp the bag opening with the bag clamp. Then, the material in the buffer hopper 2 enters the feeder 3. The feeder 3 uses large and small screw feeders and is controlled by the flip door of the controller to allow the material to flow into the packaging bag. The dust generated during the material falling is collected by the dust removal system connected to the dust cover 5. The weight of the material in the packaging bag is weighed by the weighbridge. After the specified weight is reached, the controller flip door closes, the feeder 3 stops, the weighing is completed, and the packaging bag can be removed.
[0038] When the packaging machine is packaging small bags, the small bag clamp 7 is installed to clamp the opening of the packaging bag. Then, the material in the buffer hopper 2 enters the feeder 3. The feeder 3 uses large and small spiral feeders and is controlled by the flip door of the controller to allow the material to flow into the packaging bag. The dust generated during the material falling is collected by the dust removal system connected to the dust cover 5. The weight of the material in the packaging bag is weighed by the sensor on the weighing frame 8. After the specified weight is reached, the controller flip door closes, the feeder 3 stops, the weighing is completed, and the packaging bag can be removed.
