Description

Technical Field

[0001] The invention belongs to the technical field of molecular sieve packaging equipment, in particular to a molecular sieve degassing packaging machine. Background Art

[0002] Molecular sieve is a kind of aluminosilicate material with a specific pore size. Its pore structure can adsorb and separate molecules of different sizes. However, during the production, storage and transportation, molecular sieve may adsorb gas molecules in the air, especially water vapor and other volatile organic compounds. These adsorbed gas molecules will occupy the pores of the molecular sieve, affecting its adsorption capacity and separation effect. Therefore, when packaging molecular sieves, degassing packaging is generally adopted. Degassing packaging helps to remove the gas molecules adsorbed in the molecular sieve, restore its original adsorption performance, and protect the molecular sieve from the influence of environmental humidity and other pollutants.

[0003] A patent application with publication number CN217706427U discloses a ton bag degassing packaging machine, a packaging machine frame, a feed buffer bin is arranged in the middle of the upper part of the packaging machine frame, the feed buffer bin includes a bin body, a feeding pipe is connected to the lower part of the bin body, a feeding spiral mechanism suitable for stirring materials is arranged in the middle of the bin body and the feeding pipe, and a negative pressure degassing mechanism suitable for degassing ton bags is arranged on the upper part of the bin body; the utility model performs degassing by the negative pressure degassing mechanism and the feed buffer bin in upper and lower sections, thereby reducing the degassing workload, fully degassing and having high degassing efficiency.

[0004] In the above-mentioned prior art, when in use, the molecular sieve is poured into a hopper. After entering the hopper, the molecular sieve is transported by an auger so that the molecular sieve is discharged into a bag through a material pipe. Since the molecular sieve has efficient adsorption characteristics and can adsorb gas or liquid molecules, the surface properties of the molecular sieve will change after absorbing moisture, resulting in enhanced interaction between particles, thereby easily forming agglomerates. When the size of the formed agglomerates is too large to pass through the gap between the spiral blades of the auger, the molecular sieve will form a blockage at the discharge port, thereby affecting the normal operation of subsequent discharge.

[0005] To this end, the present invention provides a molecular sieve degassing packaging machine. Summary of the invention

[0016] Preferably, a plurality of limiting plates are fixedly connected to the upper surface of the limiting frame, and the roller is located between the limiting plates and the fixed plates.

[0017] The beneficial effects of the present invention are as follows: 1. The molecular sieve degassing packaging machine described in the present invention is provided with a rotating plate, a tooth plate and a filter plate. The molecular sieve enters the hopper, and the molecular sieve that has agglomerated into blocks is screened through the filter holes on the filter plate, so that the large blocks of molecular sieve remain above the filter plate. At this time, the rotating plate drives the moving rod to rotate, and the moving rod drives the large blocks of molecular sieve to rotate. The large blocks of molecular sieve move to the tooth plate, and the moving rod and the tooth plate engage with each other to crush the large blocks of molecular sieve, so that the agglomerated large blocks of molecular sieve are broken up. Subsequently, the molecular sieve is driven by the rotating plate to the filter holes and discharged into the auger, so that the agglomerated large blocks of molecular sieve can be broken up, thereby avoiding the problem that the molecular sieve agglomerates are too large to pass through the gap between the spiral blades of the auger, thereby causing blockage.

When the moving rod moves to the convex plate, the convex plate squeezes the moving rod to move downward, and the moving rod slides downward inside the rotating plate. When the moving rod moves to just above the filter hole, the convex plate squeezes the moving rod to move inside the filter hole. At this time, the moving rod can dredge the molecular sieve blocked inside the filter hole, and then the moving rod drives the filter plate to rotate synchronously. When one end of the moving rod is separated from the squeezing of the convex plate, the first spring drives the moving rod to reset, the moving rod is separated from the filter hole, and the filter plate is reset by the second spring. This structure can dredge the molecular sieve blocked inside the filter hole to prevent the agglomerated molecular sieve from clogging the filter hole, making the remaining molecular sieves unable to pass through, affecting the normal operation of subsequent feeding.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 5As shown, a molecular sieve degassing packaging machine according to an embodiment of the present invention comprises a chassis 1, a lifting mechanism 14 is slidably provided on the front end surface of the chassis 1, a bag clamping mechanism 8 is provided at one end of the lifting mechanism 14, a conveying plate 7 is provided at the other end of the lifting mechanism 14, a hopper 2 is fixedly connected to the front end surface of the chassis 1, a material pipe 6 is fixedly connected to one end of the hopper 2, a rotating rod 22 is rotatably connected inside the hopper 2, a rotating plate 24 is fixedly connected to the surface of the rotating rod 22, an auger 25 is fixedly connected to the surface of the rotating rod 22 and located at the bottom side of the rotating plate 24, a plurality of moving rods 242 are slidably connected inside the rotating plate 24, The inner wall of the hopper 2 is rotatably connected to a filter plate 3, and a plurality of filter holes 31 are arranged inside the filter plate 3. A tooth plate 5 is fixedly connected inside the hopper 2 and on the upper side of the filter plate 3. A plurality of tooth grooves 51 are arranged inside the tooth plate 5, and the position of each tooth groove 51 corresponds to the position of each moving rod 242. A connecting pipe 101 is fixedly connected to the surface of the material pipe 6, a filter element sleeve 112 is arranged on the upper surface of the hopper 2, a feed port 26 is opened on the upper surface of the hopper 2, a weighing sensor is arranged between the lifting mechanism 14 and the bag clamping mechanism 8, and a control panel 13 is fixedly arranged on one side of the chassis 1.

[0023] like Figure 1 As shown, the lower surface of the chassis 1 is fixedly connected to a base plate 9, the upper surface of the base plate 9 is fixedly connected to a negative pressure fan 10, the output end of the negative pressure fan 10 is fixedly connected to one end of a connecting pipe 101, and a plurality of degassing holes 61 are provided at one end of the material pipe 6.

[0024] like Figure 1 As shown, a vacuum pump 11 is fixedly connected to the upper surface of the bottom plate 9 , and a degassing pipe 111 is fixedly connected between the output end of the vacuum pump 11 and the filter element sleeve 112 .

[0025] Specifically, the prior art pours the molecular sieve into the hopper 2, and after the molecular sieve enters the hopper 2, it is transported by the auger 25, so that the molecular sieve is discharged into the bag through the material pipe 6; However, in the above-mentioned prior art process, the molecular sieve has a highly efficient adsorption characteristic and can adsorb gas or liquid molecules. After the molecular sieve absorbs water, its surface properties will change, resulting in enhanced interaction between particles, which makes it easy to form agglomerates. When the size of the formed agglomerates is too large to pass through the gap between the spiral blades of the auger 25, the molecular sieve will form a blockage at the discharge port, thereby affecting the normal operation of subsequent discharge. The lifting mechanism 14 and the bag clamping mechanism 8 in this embodiment refer to the prior art, the application number is: CN213893044U, and the name is: A lifting mechanism and bag clamping device in a small automatic degassing packaging machine; The working principle of this embodiment is as follows: the bag is fixed under the lifting mechanism 14 by using the bag clamping mechanism 8, and then the molecular sieve is poured into the feed port 26 so that the molecular sieve enters the hopper 2. At this time, the rotating rod 22 is driven to rotate, and the rotating rod 22 drives the auger 25 to rotate, and the auger 25 drives the molecular sieve to move to the inside of the material pipe 6. At the same time, the vacuum pump 11 can be turned on to work. The vacuum pump 11 is connected to the filter cartridge sleeve 112 through the degassing pipe 111, and the air contained in the molecular sieve is discharged through the filter cartridge sleeve 112, and the dust carried in the molecular sieve is discharged by the filter cartridge sleeve 112. The liquid is filtered and then discharged into the bag through the material pipe 6. At the same time, the lifting mechanism 14 is driven to drive the conveying plate 7 to move upward. The conveying plate 7 supports the bottom of the bag and drives the packaging bag to move upward. The weight of the molecular sieve inside the packaging bag is measured by the weighing sensor. When the molecular sieve inside the packaging bag is bagged, the negative pressure fan 10 is driven to work. The negative pressure fan 10 sends the negative pressure air into the inside of the material pipe 6 through the connecting pipe 101. Then the air in the packaging bag is extracted through the degassing hole 61. After the bagging is completed, the lifting mechanism 14 is driven to drive the packaging bag to descend to the initial position. When the molecular sieves agglomerate to form aggregates, large aggregates fall on the top of the filter plate 3, and the rest of the molecular sieves are discharged into the gaps of the blades of the auger 25 through the filter holes 31. The rotating rod 22 drives the rotating plate 24 to rotate, and the rotating plate 24 drives the moving rod 242 to move. The moving rod 242 pushes the aggregates to rotate on the filter plate 3 to the tooth plate 5. The tooth grooves 51 between the moving rod 242 and the tooth plate 5 are engaged to break up the aggregates, so that the aggregates are dispersed into small pieces. The subsequent rotating plate drives the molecular sieves after breaking to move, so that the molecular sieves are discharged from the filter holes 31 into the gaps of the auger 25 for feeding operation; This embodiment can break up the agglomerated large pieces of molecular sieve to prevent the molecular sieve agglomerates from being too large to pass through the gaps between the spiral blades of the auger 25, thereby causing blockage.

[0026] like Figure 1 As shown, a screw feeder 12 is fixedly disposed at one end of the feed port 26 , and one end of the screw feeder 12 is fixedly disposed on the upper surface of the chassis 1 .

[0027] Specifically, the screw feeder 12 adopts the screw feeder in the prior art, and the molecular sieve enters the interior of the screw feeder 12, driving the bolt blades inside the screw feeder 12 to rotate, so that the molecular sieve moves to the feed port 26, making it convenient for the molecular sieve to enter the interior of the hopper 2.

[0028] like Figure 4 As shown, a motor 21 is fixedly connected to the upper surface of the hopper 2, and the output end of the motor 21 is fixedly connected to one end of a rotating rod 22. A scraper 23 is fixedly connected to the surface of the rotating rod 22 and located on the upper side of a rotating plate 24, and one end of the scraper 23 is in contact with the inner wall of the hopper 2.

[0029] Specifically, the driving motor 21 is turned on, the motor 21 drives the rotating rod 22 to rotate, the rotating rod 22 drives the scraper 23, the rotating plate 24 and the auger 25 to rotate, the scraper 23 stirs the material inside the hopper 2, and at the same time scrapes the inner wall of the hopper 2 to prevent the molecular sieve from adhering to the inner wall of the hopper 2.

[0030] Embodiment 2: Figures 5 to 9 As shown, compared with Example 1, another implementation of the present invention is: a plurality of through holes 241 are opened on the inner lower surface of the rotating plate 24, a first spring 243 is fixedly connected to the surface of the moving rod 242 and the inner lower surface of the rotating plate 24, a plurality of convex plates 4 are fixedly connected to the inner wall of the hopper 2, each of the convex plates 4 is located directly above the filter hole 31, and the sizes of the through holes 241 and the filter hole 31 match the size of the moving rod 242.

[0031] like Figure 5 As shown, the lower surface of the rotating plate 24 is in contact with the upper surface of the filter plate 3, one end of the moving rod 242 is configured to be arc-shaped, and the cross-sectional shape of the convex plate 4 is configured to be an isosceles trapezoid.

[0032] like Figure 6 As shown, a plurality of rollers 33 are fixedly provided on the lower surface of the filter plate 3, the rollers 33 are internally slidably connected to a limiting frame 32, the limiting frame 32 is fixedly connected to the inner wall of the hopper 2, the upper surface of the limiting frame 32 is fixedly connected to a fixing plate, and a second spring 35 is fixedly connected between the fixing plate and the lower surface of the filter plate 3.

[0033] like Figure 6 As shown, a plurality of limiting plates 34 are fixedly connected to the upper surface of the limiting frame 32 , and the roller 33 is located between the limiting plates 34 and the fixed plates.

[0034] Specifically, the agglomerated molecular sieve forms agglomerates. When the agglomerates are embedded in the filter holes 31, the filter holes 31 are blocked. When the filter holes 31 are blocked, the remaining molecular sieves cannot pass through. When the rotating plate 24 rotates, the molecular sieves inside the filter holes 31 cannot be cleared, which affects the normal discharge problem. When the present embodiment is in use, the rotating plate 24 drives the moving rod 242 to rotate synchronously. When the moving rod 242 moves to one side of the convex plate 4, as the moving rod 242 is driven by the rotating plate 24 to rotate, the moving rod 242 slides and is squeezed on one side of the convex plate 4, so that the moving rod 242 slides downward inside the rotating plate 24. When the moving rod 242 moves to just above the filter hole 31, one end of the moving rod 242 is at the bottom of the convex plate 4, and the moving rod 242 enters the inside of the filter hole 31. The moving rod 242 pushes the molecular sieve inside the filter hole 31, so that the moving rod 242 can clear the filter hole 31. At this time, the moving rod 242 is located inside the filter hole 31, and then the rotating plate 24 drives the moving rod 242 to move. When the rod 242 rotates, the filter hole 31 is limited, so that the rotating plate 24 drives the moving rod 242 to rotate, and the moving rod 242 drives the filter plate 3 to rotate synchronously, and the filter plate 3 drives the roller 33 to slide in the limiting frame 32 and squeeze the second spring 35. When one end of the moving rod 242 is separated from and fits against the lower surface of the convex plate 4, the moving rod 242 is driven upward by the first spring 243, and the moving rod 242 is separated from the filter hole 31. The moving rod 242 releases the limitation on the filter hole 31, so that the filter plate 3 is reset to the limiting plate 34 through the second spring 35. The above operation can be repeated to dredge the remaining filter holes 31 to avoid the problem of molecular sieve agglomerates blocking the filter holes 31 and affecting the subsequent normal discharge.

[0035] Working principle: use the bag clamping mechanism 8 to fix the bag just below the lifting mechanism 14, then pour the molecular sieve into the feed port 26, so that the molecular sieve enters the inside of the hopper 2, turn on the motor 21, the motor 21 drives the rotating rod 22 to rotate, the rotating rod 22 drives the auger 25 to rotate, the auger 25 drives the molecular sieve to move to the inside of the material pipe 6, and at the same time, the vacuum pump 11 can be turned on to work, the vacuum pump 11 is connected to the filter cartridge sleeve 112 through the degassing pipe 111, the air contained in the molecular sieve is discharged through the filter cartridge sleeve 112, and the filter cartridge sleeve 112 carries the The dust is filtered and then discharged into the bag through the material pipe 6. At the same time, the lifting mechanism 14 is driven to drive the conveying plate 7 to move upward. The conveying plate 7 supports the bottom of the bag and drives the packaging bag to move upward. The weight of the molecular sieve inside the packaging bag is measured by the weighing sensor. When the molecular sieve inside the packaging bag is bagged, the negative pressure fan 10 is driven to work. The negative pressure fan 10 sends negative pressure air into the inside of the material pipe 6 through the connecting pipe 101. Then the air in the packaging bag is extracted through the degassing hole 61. After the bagging is completed, the lifting mechanism 14 is driven to drive the packaging bag to descend to the initial position. When the molecular sieves agglomerate to form aggregates, large aggregates fall on the top of the filter plate 3, and the rest of the molecular sieves are discharged into the gaps of the blades of the auger 25 through the filter holes 31. The rotating rod 22 drives the rotating plate 24 to rotate, and the rotating plate 24 drives the moving rod 242 to move. The moving rod 242 pushes the aggregates to rotate on the filter plate 3 to the tooth plate 5. The tooth grooves 51 between the moving rod 242 and the tooth plate 5 are engaged to break up the aggregates, so that the aggregates are dispersed into small pieces. The subsequent rotating plate drives the molecular sieves after breaking to move, so that the molecular sieves are discharged from the filter holes 31 into the gaps of the auger 25 for feeding operation; The rotating rod 22 drives the rotating plate 24 to rotate, and the rotating plate 24 drives the moving rod 242 to rotate synchronously. When the moving rod 242 moves to one side of the convex plate 4, as the moving rod 242 is driven by the rotating plate 24 to rotate, the moving rod 242 slides and is squeezed on one side of the convex plate 4, so that the moving rod 242 slides downward inside the rotating plate 24. When the moving rod 242 moves to the top of the filter hole 31, one end of the moving rod 242 is at the bottom of the convex plate 4, and the moving rod 242 enters the inside of the filter hole 31. The moving rod 242 pushes the molecular sieve inside the filter hole 31, so that the moving rod 242 can dredge the filter hole 31. At this time, the moving rod 242 is located at the filter hole 31, and then when the rotating plate 24 drives the moving rod 242 to rotate, the filter hole 31 is limited, so that when the rotating plate 24 drives the moving rod 242 to rotate, the moving rod 242 drives the filter plate 3 to rotate synchronously, and the filter plate 3 drives the roller 33 to slide in the limiting frame 32 and squeeze the second spring 35. When one end of the moving rod 242 is separated from and fits the lower surface of the convex plate 4, the moving rod 242 is driven upward by the first spring 243, and the moving rod 242 is separated from the filter hole 31. The moving rod 242 releases the limit of the filter hole 31, so that the filter plate 3 is reset to the limiting plate 34 through the second spring 35. Repeat the above operation to dredge the remaining filter holes 31.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
