Description

Technical Field

[0001] This utility model relates to a waste material recycling device for valve bag packaging machines, belonging to the field of valve bag packaging machines. Background Technology

[0002] Powder material valve packaging machine is an automated equipment that integrates filling and bag sealing. During the filling process, some powder material may leak out, which requires a residual material recovery device to absorb the leaked powder. However, the residual material recovery devices currently on the market are prone to powder back-blowing defects, which will cause the recovered powder material to be unable to be output from the residual material recovery device. Utility Model Content

[0003] The purpose of this invention is to provide a waste material recycling device for valve bag packaging machines, which can effectively solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] The recycling structure includes a recycling bin, a recycling hopper, and an opening and closing device between the recycling bin and the recycling hopper.

[0006] The opening and closing device includes a flange ring, a cylinder is provided outside the flange ring, a gearbox is provided at the output end of the cylinder, a rotating shaft is provided at the output end of the gearbox, the rotating shaft is rotatably located in the middle position inside the flange ring, and a flipping plate is provided on the rotating shaft.

[0007] Furthermore: the recycling bin comprises a cuboid feeding box and a discharge bin disposed below the feeding box. The feeding box has a feeding port on one side and an installation port at the top, and a material extractor is disposed on the installation port.

[0008] The upper end of the feeding hopper is connected to the lower edge of the feeding box body, and the lower end is connected to the upper end face of the flange ring; the upper opening of the feeding hopper is rectangular and the lower opening is circular.

[0009] Furthermore: the recycling bin includes a cylindrical section and a conical section located within the cylindrical section, and an output pipe is provided at the lower end of the conical section.

[0010] Furthermore: a connecting pipe is provided on one side of the cylindrical section, an air pipe is connected to the connecting pipe, and an air pump is connected to one end of the air pipe.

[0011] Furthermore: a first inclined plate and a second inclined plate are provided on one side of the feeding box; the feeding hopper is composed of four inclined triangular plates and an arc plate disposed between the triangular plates; the feeding port is disposed on the first inclined plate, and the inclination angle of the second inclined plate is the same as the inclination angle of one of the triangular plates.

[0012] The beneficial effects are:

[0013] The opening and closing device closes the gap between the waiting bin and the recycling bin. Powder entering the waiting bin falls directly onto the opening and closing device. When too much powder accumulates on the opening and closing device, it can be opened, and the powder will flow from the waiting bin into the recycling bin. This design is mainly to facilitate the output of powder in the future.

[0014] The cylindrical section of the recycling hopper is mainly for the purpose of installing a connecting pipe. An air pipe is connected to the connecting pipe, and an air pump is connected to one end of the air pipe.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] See Figure 1-4 This is one embodiment of a waste material recycling device for a valve bag packaging machine according to the present invention.

[0027] The device includes a recycling structure 1, which consists of a recycling bin 2, a recycling bin 3, and an opening and closing device 4 between the recycling bin 2 and the recycling bin 3. The recycling bin 2 is equipped with a material extractor. While extracting air, the material extractor carries the extracted powder into the recycling bin 2. At this time, the opening and closing device 4 closes the gap between the recycling bin 2 and the recycling bin 3. The powder entering the recycling bin 2 will fall directly onto the opening and closing device 4. When too much powder accumulates on the opening and closing device 4, the opening and closing device 4 can be opened, and the powder will enter the recycling bin 3 from the recycling bin 2. This design is mainly to facilitate the subsequent output of powder.

[0028] The opening and closing device 4 is a pneumatic butterfly valve, specifically including a flange ring 41, a cylinder 42 is provided outside the flange ring 41, a gearbox 43 is provided at the output end of the cylinder 42, a rotating shaft is provided at the output end of the gearbox 43, the rotating shaft is rotatably located in the middle position inside the flange ring 41, and a flip plate 44 is provided on the rotating shaft.

[0029] The opening and closing device 8 in this device adopts an automatic opening and closing method. When in use, the cylinder 42 is started, the cylinder 42 drives the gearbox 43 to rotate, the gearbox 43 drives the rotating shaft, and then drives the tilting plate 44 to rotate, thereby realizing the opening and closing of the flange ring 41.

[0030] The recycling bin 2 consists of a rectangular feeding box 21 and a discharge bin 22 located below the feeding box 21. The feeding box 21 has a feeding port 23 on one side and an installation port 24 at the top. A material extractor is installed on the installation port 24.

[0031] The upper end of the feeding hopper 22 is connected to the lower edge of the feeding box 21, and the lower end is connected to the upper end face of the flange ring 41; the upper opening of the feeding hopper 22 is rectangular, and the lower opening is circular.

[0032] In this device, the recovery bin 2 is equipped with a rectangular feed box 21 and a specially shaped discharge bin 22 to facilitate the extraction of powder and its falling onto the tilting plate 44 on the opening and closing device 8 below. The shape of the feed box 21 is mainly to facilitate the extraction of powder and to accommodate the feeding machine. The shape of the discharge bin 22 is mainly to facilitate the smooth falling of powder and to accommodate the circular tilting plate 44 below.

[0033] The recycling bin 3 includes a cylindrical section 31 and a conical section 32 located on the cylindrical section 31. An output pipe 33 is provided at the lower end of the conical section 32.

[0034] The cylindrical section 31 of the recycling bin 3 is mainly for the purpose of setting up the connecting pipe 34. The connecting pipe 34 is connected to an air pipe, and one end of the air pipe is connected to an air pump. The air pump can introduce high-speed airflow into the recycling bin 3 to facilitate blowing out the powder. At the same time, when the high-speed airflow is flowing in, the flip plate 44 of the opening and closing device 4 is in a closed state, which can prevent the powder from being blown out.

[0035] It is understandable that an air pump is an air compressor, which generates air.

[0036] The feed box 21 has a first inclined plate 211 and a second inclined plate 212 on one side. The discharge hopper 22 is composed of four inclined triangular plates 221 and an arc plate 222 disposed between the triangular plates 221. The feed inlet 23 is disposed on the first inclined plate 211. The inclination angle of the second inclined plate 212 is the same as the inclination angle of one of the triangular plates 221.

[0037] In order to facilitate the smooth entry of powder into the recycling bin 2, the structure of the feed box 21 in this device has also been improved. The tilt angle of the second inclined plate 212 is the same as the tilt angle of one of the triangular plates 221, so that it can be formed with the plane, allowing the powder to slide down without obstruction. The setting of the second inclined plate 211 can make the feed inlet 23 tilt upward, which facilitates the entry of powder.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
