[0003] When the existing air chute type packaging machine ash return conveying device is in use, due to the force of air, the raw materials inside the conveying chute will generate a large amount of dust. This dust not only affects the surrounding environment, but also wastes the raw materials. Therefore, it does not have the function of recycling and reusing this dust and fine particulate raw materials. Utility Model Content

[0004] The purpose of this invention is to provide an air chute type ash return conveying device for packaging machines, in order to solve the problem mentioned in the background art that the currently used air chute type ash return conveying devices for packaging machines do not have the function of collecting and utilizing dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air chute type package return ash conveying device, comprising: a conveying chute and a feeding hopper, wherein an air compressor is installed at one end of the conveying chute, and the feeding hopper is installed at the top of the conveying chute;

[0006] A screw conveyor is mounted on the top of the conveying chute via a fixed frame. A collection pipe is mounted on the top of the screw conveyor. Dust pipes are connected to both sides of the collection pipe. A vacuum cleaner is connected to one end of the collection pipe. A first discharge pipe is installed at the bottom of the vacuum cleaner and at the top of the screw conveyor. A drive belt is connected between the vacuum cleaner and the screw conveyor via a pulley. A second discharge pipe is installed at the end of the screw conveyor near the feed hopper.

[0007] Preferably, the air compressor has an outer casing, and a drying chamber is connected to the inside of the outer casing via a sliding groove. A drying plate is installed inside the drying chamber, and a heating wire is installed in the middle of the drying plate via a bracket. A filter screen is installed on one side of the outer casing.

[0008] Preferably, a baffle is connected to one side of the outer casing via a pivot, and a locking block is installed on the top of the baffle via a groove.

[0009] Preferably, the bottom of the card block is equipped with a protrusion that penetrates the baffle, and a card rod is inserted into one side of the protrusion.

[0010] Preferably, a fixing block is sleeved on the outer side of the clamping rod, and a movable spring connects the fixing block and the clamping rod.

[0011] Preferably, the interior of the conveying chute is slidably connected to a movable frame via a slide groove, the inner wall of the movable frame is slidably connected to a slider via a slide groove, and a scraper is connected between the two sets of sliders.

[0012] Preferably, a connecting rod that passes through the movable frame is installed on the top of the scraper, and a telescopic spring is installed inside the connecting rod through a groove.

[0013] Preferably, a telescopic block through the connecting rod is installed on the top of the telescopic spring, and a threaded sleeve through the conveying chute is connected to one side of the movable frame.

[0014] Preferably, a lead screw is connected through the middle of the screw sleeve, and the input end of the lead screw is connected to a drive motor via a coupling.

[0015] Preferably, a screw is inserted into one side of the connecting rod, and a mounting block is sleeved on the outside of the screw, with the mounting block installed on the top of the conveying chute.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the air chute type packaging machine ash return conveying device, the motor at one end of the screw conveyor can be started, and with the cooperation of the transmission belt, the vacuum cleaner can work. The vacuum cleaner can suck the dust into one side of the vacuum cleaner through the dust pipe and the collection pipe, and then drop it onto the screw conveyor through the first discharge pipe. Then, the screw conveyor will transport the dust material back to the conveying chute, thus facilitating the collection and recycling of the dust material. This is the characteristic of the use of the air chute type packaging machine ash return conveying device.

[0017] 1. In use, the air chute type dust return conveying device can suck dust into one side of the dust collector through the dust pipe and collect the dust through the dust pipe. The dust then falls onto the screw conveyor through the first discharge pipe. The dust material is then transported back to the conveying chute through the feed hopper by the screw conveyor and the second discharge pipe at the bottom, thus avoiding the waste of raw materials.

[0018] 2. In use, this air-assisted inclined chute ash conveying device can draw air into the drying chamber through a fan, and quickly dry the moisture in the air through the heating wires on the drying plate inside the drying chamber. Then, the dried air is delivered to the conveying chute by an air compressor, thereby avoiding the impact of humid air on the raw materials. It can also quickly rotate the baffle to the bottom of the outer shell, thus facilitating the inspection and maintenance of the drying chamber inside the outer shell.

[0019] 3. In use, the connecting rod of this air-driven inclined conveyor for ash return can be pushed into the conveying inclined chute, causing the connecting rod to drive the scraper to move downwards along the movable frame. When the bottom of the scraper contacts the inner wall of the conveying inclined chute, it squeezes the telescopic block, causing the telescopic block to fully retract into the connecting rod. Then, the drive motor drives the lead screw to rotate, and with the cooperation of the screw sleeve, the movable frame drives the scraper to slide along the slide of the conveying inclined chute. The scraper can scrape and clean the waste residue remaining on the inner wall of the conveying inclined chute, thereby preventing blockage inside the conveying inclined chute.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 This utility model provides a technical solution: an air chute type package return ash conveying device, including: a conveying chute 1 and a feeding hopper 3, an air compressor 2 is installed at one end of the conveying chute 1, and the feeding hopper 3 is installed at the top of the conveying chute 1;

[0029] A screw conveyor 4 is mounted on the top of the conveying chute 1 via a fixed frame. A collection pipe 5 is mounted on the top of the screw conveyor 4. Dust pipes 6 are connected to both sides of the collection pipe 5. A vacuum cleaner 7 is connected to one end of the collection pipe 5. A first discharge pipe 8 is installed at the bottom of the vacuum cleaner 7 and the top of the screw conveyor 4. A drive belt 9 is connected between the vacuum cleaner 7 and the screw conveyor 4 via a pulley. A second discharge pipe 10 is installed at the end of the screw conveyor 4 near the feed hopper 3. Multiple sets of dust pipes 6 are evenly and symmetrically installed along the collection pipe 5.

[0030] In practical implementation, this air-assisted inclined chute dust collection and conveying device can start the motor at one end of the screw conveyor 4. The connecting shaft at the output end of the screw conveyor 4 is connected to the connecting shaft at the output end of the vacuum cleaner 7 via a pulley and a drive belt 9. Therefore, the rotation of the screw conveyor 4 will drive the fan in the vacuum cleaner 7 to rotate through the drive belt 9. One end of the vacuum cleaner 7 is connected to a collection pipe 5, and the bottom of the collection pipe 5 is connected to a dust pipe 6. When the fan in the vacuum cleaner 7 is working, it will convey dust through the collection pipe 5 and the dust pipe 6. Dust in the chute 1 is drawn into the collection pipe 5, and through the collection pipe 5 and the dust collector 7, the dust is discharged from the first discharge pipe 8 to the screw conveyor 4. When the screw conveyor 4 is working, it will transport the dust or fine particles upward. Since the second discharge pipe 10 at the bottom of the screw conveyor 4 is set at the top of the feed hopper 3, the dust or fine particles can be transported back to the conveying chute 1 through the screw conveyor 4, which facilitates the recycling and collection of dust or fine particles and can reduce resource waste and environmental pollution.

[0031] See Figure 1 and Figure 2 It can be seen that during use, the dust or fine particles are sucked into the dust collector through the dust pipe 6 and the collection pipe 5 by the dust collector 7, and fall onto the screw conveyor through the first discharge pipe 8 at the bottom of the dust collector. Then, the dust or fine particles can be transported back to the conveying chute 1 through the feed hopper 3 by the screw conveyor 4, so as to effectively recover and utilize the dust generated during the conveying process.

[0032] An outer casing 11 is installed on the outside of the air compressor 2. A drying chamber 12 is connected to the inside of the outer casing 11 via a sliding groove. A drying plate 13 is installed inside the drying chamber 12. A heating wire 14 is installed in the middle of the drying plate 13 via a bracket. A filter screen 15 is installed on one side of the outer casing 11. A baffle 16 is connected to one side of the outer casing 11 via a rotating shaft. A locking block 17 is installed on the top of the baffle 16 via a groove. A protrusion 18 penetrating the baffle 16 is installed on the bottom of the locking block 17. A locking rod 19 is inserted into one side of the protrusion 18. A fixing block 20 is sleeved on the outside of the locking rod 19. A movable spring 21 is connected between the fixing block 20 and the locking rod 19. The fixing block 20 is installed on one side of the baffle 16.

[0033] In practical implementation, the air chute type packaging machine ash conveying device can draw air into the drying box 12 through the fan inside the drying box 12, and filter the dust and impurities in the air through the filter screen 15 on the side of the outer shell 11. The heating wire 14 is installed in the middle of the drying plate 13 through the bracket. The heating wire 14 can generate high temperature. When the air passes through the drying plate 13, the surrounding high temperature can quickly dry the moisture in the air, thereby achieving the effect of drying the air. The dried air can be transported to the conveying chute 1 through the pipeline and the air compressor 2, thereby avoiding the humid air from affecting the conveying effect of the raw materials.

[0034] Simultaneously, the lever 19 can be pulled along the fixing block 20 towards one side of the protrusion 18, so that the lever 19 does not limit the protrusion 18. At the same time, the lever 19 will cause the outer sleeved movable spring 21 to be in a compressed state. Without the limiting effect of the lever 19 on the protrusion 18, under the action of gravity, the locking block 17 at the top of the baffle 16 will retract into the groove of the baffle 16 and move out of the groove of the outer shell 11. Without the limiting effect of the locking block 17, the baffle 16 can be rotated to the bottom of the outer shell 11 by the pivot. At this time, it is convenient to adjust the outer shell 11. 1. The internal heating wire 14 and fan can be better inspected. Conversely, the baffle 16 can be rotated to the side of the outer casing 11, and then the locking block 17 can be pushed upward by the protrusion 18, so that the protrusion 18 presses the locking rod 19 to one side through the inclined surface. When the locking block 17 is engaged in the groove of the outer casing 11, the groove on the side of the protrusion 18 will be aligned with the locking rod 19. At this time, the locking rod 19 will be re-inserted into one side of the protrusion 18 by the reset action of the movable spring 21. The baffle 16 can protect the heating wire 14 and fan in the drying oven 12.

[0035] See Figure 1 , Figure 3 and Figure 4It can be seen that during use, air can be drawn into the drying chamber 12 by a fan, and the air is dried by the drying plate 13 and heating wire 14 in the drying chamber 12. The dried air is then transported to the conveying chute 1 through the air compressor 2 and pipeline, thereby avoiding the effect of humid air on the conveying effect of raw materials. At the same time, the baffle 16 can be rotated open from one side of the outer shell 11 to facilitate the maintenance and repair of the heating wire 14 and fan inside the drying chamber 12.

[0036] A movable frame 22 is slidably connected inside the conveying chute 1 via a sliding groove. A slider 23 is slidably connected to the inner wall of the movable frame 22 via a sliding groove. A scraper 24 is connected between two sets of sliders 23. A connecting rod 25 penetrating the movable frame 22 is installed on the top of the scraper 24. A telescopic spring 26 is installed inside the connecting rod 25 via a groove. A telescopic block 27 penetrating the connecting rod 25 is installed on the top of the telescopic spring 26. A threaded sleeve 28 penetrating the conveying chute 1 is connected to one side of the movable frame 22. A lead screw 29 is connected through the middle of the threaded sleeve 28. A drive motor 30 is connected to the input end of the lead screw 29 via a coupling. A screw 31 is inserted into one side of the connecting rod 25. An installation block 32 is sleeved on the outside of the screw 31. The installation block 32 is installed on the top of the conveying chute 1. The telescopic block 27 forms a telescopic structure with the connecting rod 25 via the telescopic spring 26.

[0037] In practical implementation, when the air-assisted inclined chute type ash return conveying device needs to clean the residual ash residue on the inner wall of the conveying inclined chute 1, the screw 31 can be rotated. Since the screw 31 and the mounting block 32 are threadedly connected, and the mounting block 32 is installed at the top of the conveying inclined chute 1, rotating the screw 31 will allow the screw 31 to move out of the groove on the side of the connecting rod 25. At the same time, the screw 31 will not limit the connecting rod 25, and then the connecting rod 25 can be pushed into the interior of the conveying inclined chute 1, causing the scraper 24 to slide down along the slide groove of the movable frame 22 through the sliders 23 on both sides, and contact the bottom of the conveying inclined chute 1. At the same time, the telescopic block 27 is pushed into the interior of the connecting rod 25. The compression causes the telescopic block 27 to completely retract into the groove of the connecting rod 25 through the groove at the top of the conveying chute 1. The telescopic block 27 is then not connected to the through hole at the top of the conveying chute 1. Then the drive motor 30 can be started. The drive motor 30 will drive the lead screw 29 to rotate through the coupling. A threaded sleeve 28 is also sleeved on the outside of the lead screw 29. The threaded sleeve 28 is installed on the side of the movable frame 22, and the other end of the movable frame 22 is slidably connected to the inside of the conveying chute 1 through the sliding groove. Therefore, when the lead screw 29 rotates, the movable frame 22 can be driven to slide along the inner wall of the conveying chute 1 through the threaded sleeve 28, so that the scraper 24 can scrape and clean the residual ash inside the conveying chute 1.

[0038] Conversely, the lead screw 29 can drive the sleeve 28 to slide in the opposite direction. When the sleeve 28 drives the movable frame 22 and the connecting rod 25 to the through hole position at the top of the conveying chute 1, the drive motor 30 can stop working. At the same time, the telescopic spring 26 will drive the telescopic block 27 to reset, so that the telescopic block 27 moves upward from the groove of the connecting rod 25 and passes through the through hole of the conveying chute 1. Then, the connecting rod 25 pulls the scraper 24 upward, so that the scraper 24 moves upward along the movable frame 22 through the slider 23 and rotates the screw 31, so that the screw 31 is inserted into the groove on the side of the connecting rod 25. The screw 31 can limit the connecting rod 25 and the scraper 24, so that the scraper 24 is at the top and will not interfere with the feeding effect of the conveying chute 1.

[0039] See Figure 1 , Figure 5 and Figure 6 As can be seen, during use, the scraper 24 can be pushed to the bottom by the connecting rod 25 according to the usage requirements. Then, with the cooperation of the screw 29 and the screw sleeve 28, the scraper 24 can slide along the conveying chute 1, thereby scraping and cleaning the residual ash inside the conveying chute 1, and avoiding the phenomenon of excessive residual ash inside the conveying chute 1 causing blockage.

[0040] In summary, when using this air-driven inclined chute ash return conveying device, the raw materials to be conveyed can be poured into the conveying chute 1 through the feed inlet. The inclined angle of the conveying chute 1 and gravity cause the raw materials to move downwards along the chute 1. Simultaneously, the air compressor 2 at one end of the conveying chute 1 is activated, compressing the air and conveying the compressed gas through a pipeline to the conveying chute 1. The raw materials in the conveying chute 1 continue to move forward under the propulsion of the gas, thus facilitating the conveying of the raw materials. This is the characteristic of the air-driven inclined chute ash return conveying device. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
