Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a vertical full-automatic packaging machine circulating cooling device based on negative pressure suction. Background Art

[0002] During the operation of a vertical fully automatic packaging machine, as particulate matter is conveyed through the feeder, a significant amount of heat is often generated due to mechanical friction, material extrusion, and the continuous operation of the equipment. If this heat cannot be dissipated promptly, the material can clump on the inner wall of the feeder or near the feeding mechanism, and may even cause problems such as overheating and deformation of equipment components and transmission system jamming, seriously affecting packaging efficiency and equipment life.

[0003] Existing technologies typically use external air or water cooling systems to cool the equipment. However, traditional air cooling only dissipates heat from the housing surface through external airflow, making it difficult to effectively dissipate heat from high-temperature areas within the feeder, such as those near the spiral blades and drive shaft. Water cooling systems, on the other hand, require additional coolant circulation piping and pumps, increasing equipment size and manufacturing costs while also creating the risk of liquid leakage and high maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to provide a circulating cooling device for a vertical fully automatic packaging machine based on negative pressure suction, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vertical fully automatic packaging machine circulating cooling device based on negative pressure suction, comprising a packaging machine feeder, a lower hopper and a feeding mechanism, wherein the lower hopper is installed at the feeding end of the packaging machine feeder, and the lower hopper is connected to the packaging machine feeder; the feeding mechanism is installed inside the packaging machine feeder, and the feeding mechanism includes a drive shaft and a spiral blade installed on the drive shaft, and the drive shaft is a hollow shaft structure; a cavity is provided in the shell of the packaging machine feeder, and an opening is provided at the bottom of the cavity, and the top of the cavity is connected to the interior of the drive shaft through at least one air inlet pipe, and a negative pressure fan is also installed on the side of the packaging machine feeder, and a wind hood is provided on the air inlet side of the negative pressure fan, and the wind hood is connected to the lower end of the drive shaft through a connecting pipe.

[0006] As a further solution of the present invention: a rotating shaft is rotatably installed inside the lower hopper, and a feed blade is fixedly installed on the rotating shaft; a connecting shaft is rotatably installed outside the lower hopper, the connecting shaft is coaxially arranged with the rotating shaft, and the connecting shaft is connected to the rotating shaft of the negative pressure fan through a synchronous belt.

[0007] As a further solution of the present invention: a backup motor is fixedly installed on the outer side of the lower hopper, and the output end of the backup motor is fixedly connected to the rotating shaft.

[0008] As a further solution of the present invention: the lower end of the drive shaft extends out of the packaging machine feeder, the lower end of the drive shaft is fixedly installed with a first gear, the lower side of the packaging machine feeder is fixedly installed with a drive motor, the output end of the drive motor is fixedly installed with a second gear, and the second gear is engaged with the first gear.

[0009] As a further solution of the present invention: the lower end of the drive shaft is rotatably connected to the connecting pipe.

[0010] As a further solution of the present invention: an upper frame is installed on the upper part of the packaging machine feeder, and the air inlet pipe is embedded in the interior of the upper frame.

When the particles flow inside the packaging machine feeder, the driving shaft controls the rotation of the spiral blade so that the spiral blade pushes the particles. In this process, the negative pressure fan is started, and its air inlet side is connected to the driving shaft through the connecting pipe. A continuous suction effect is formed inside the shaft. The drive shaft, as a hollow shaft, constitutes the main air flow channel. The top of the cavity is connected to the drive shaft through the air inlet pipe, causing the air pressure inside the cavity to be lower than the external atmospheric pressure, forming a pressure gradient. Under the action of the pressure difference, the external cold air is discharged from the opening at the bottom of the cavity along the cavity, the air inlet pipe, the inside of the drive shaft, the connecting pipe, and the negative pressure fan to the external environment, completing the closed-loop flow, reducing the temperature of the particles on the inner wall of the packaging machine feeder shell and near the feeding mechanism, and avoiding the problems of material agglomeration, overheating of equipment components, and even damage to the packaging machine feeder due to the increase in temperature.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5In the embodiment of the present invention, a circulation cooling device for a vertical fully automatic packaging machine based on negative pressure suction comprises a packaging machine feeder 10, a lower hopper 20 and a feeding mechanism 70. The lower hopper 20 is installed at the feeding end of the packaging machine feeder 10. The bottom of the lower hopper 20 is connected to the packaging machine feeder 10. The granular material enters the lower hopper 20 and the packaging machine feeder 10 in sequence before packaging. The packaging machine feeder 10 is used to provide the granular material to be packaged to the packaging machine. The packaging machine in this embodiment adopts the vertical fully automatic packaging in the prior art. Installation; The feeding mechanism 70 is installed inside the packaging machine feeder 10, and the feeding mechanism 70 includes a drive shaft 71 and a spiral blade 72 installed on the drive shaft 71, and the drive shaft 71 is a hollow shaft structure; a cavity 13 is provided in the shell of the packaging machine feeder 10, and an opening is provided at the bottom of the cavity 13, which is connected to the external environment of the equipment. The opening serves as an active inlet for external cold air, and the top of the cavity 13 is connected to the interior of the drive shaft 71 through at least one air inlet pipe 12. The packaging machine feeder 10 0 is also installed on the side of the negative pressure fan 40, and the air inlet side of the negative pressure fan 40 is provided with a wind cover, which is connected to the lower end of the drive shaft 71 through the connecting pipe 50. When the particles flow inside the packaging machine feeder 10, the drive shaft 71 controls the rotation of the spiral blade 72 to push the particles. In this process, the negative pressure fan 40 is started, and its air inlet side forms a continuous suction effect on the inside of the drive shaft 71 through the connecting pipe 50. The drive shaft 71, as a hollow shaft, constitutes the main air flow channel, and the top of the cavity 13 passes through the air inlet pipe. 12 is connected to the drive shaft 71, causing the air pressure inside the cavity 13 to be lower than the external atmospheric pressure, forming a pressure gradient. Under the action of the pressure difference, the external cold air is discharged from the bottom opening of the cavity 13 along the cavity 13, the air inlet pipe 12, the inside of the drive shaft 71, the connecting pipe 50, and the negative pressure fan 40 to the external environment, completing the closed-loop flow, thereby reducing the temperature of the particles on the inner wall of the packaging machine feeder 10 shell and near the feeding mechanism 70, avoiding the problem of material agglomeration, overheating of equipment components or even damage to the packaging machine feeder 10 due to the increase in temperature.

It can be understood that when the particles enter the lower hopper 20, the particles collide with the feed blades 22 and drive the feed blades 22 to rotate, thereby driving the rotating shaft 221 and the connecting shaft 23 to rotate, so that the particles drive the negative pressure fan 40 to work during the continuous feeding process, thereby reducing the energy consumption of the circulating cooling device. In addition, in the embodiment of the present application, a backup motor 21 is also fixedly mounted on the outer side of the lower hopper 20, and the output end of the backup motor 21 is fixedly connected to the rotating shaft 221. The backup motor 21 is used to control the rotation of the rotating shaft 221. After the feeding is stopped, the rotation of the rotating shaft 221 can be continued by activating the backup motor 21.

A first gear 15 is fixedly mounted on the lower end of the drive shaft 71. A drive motor 17 is fixedly mounted on the lower side of the packaging machine feeder 10. A second gear 16 is fixedly mounted on the output end of the drive motor 17. The second gear 16 meshes with the first gear 15. The drive motor 17 controls the rotation of the drive shaft 71 via the first gear 15 and the second gear 16. In addition, the lower end of the drive shaft 71 is rotatably connected to the connecting pipe 50.

[0024] In the embodiment of the present application, an upper frame 11 is installed on the upper part of the packaging machine feeder 10, and the air inlet pipe 12 is embedded in the interior of the upper frame 11. The driving shaft 71 is located at one end inside the packaging machine feeder 10 and is rotatably installed with a sealing plate 73.

After passing through the sealing plate 73, the air inlet pipe 12 is connected to the interior of the driving shaft 71.

[0025] In addition, a discharge port 14 is provided at the bottom of the packaging machine feeder 10 , and the discharge port 14 is connected to a discharge hopper 60 . The discharge hopper 60 is used to connect to the packaging machine and provide the packaging machine with granular materials to be packaged.
