Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, and in particular to an automatic filling equipment and filling method for the production of preservatives. Background Technology

[0002] Preservatives are a class of substances that inhibit microbial activity and prevent product spoilage. To achieve a certain shelf life, it is necessary to take certain measures to prevent microbial infection and reproduction. Practice has proven that using preservatives is one of the most economical, effective, and simplest methods to achieve the above effects. The processing of preservatives requires filling, and currently, filling machines are commonly used for discharging and filling preservatives.

[0003] Currently, when solid powdered preservatives are piled up in filling equipment, the preservatives tend to stick together during filling and discharging. This not only easily leads to clumping of the preservatives but also to blockage at the discharge port of the filling equipment, making it difficult to quickly and effectively process the preservatives.

[0004] In the prior art, patent application number CN202223395049.0 discloses a filling device for preservative production, which includes a filling assembly. A drive assembly is fixedly connected within the filling assembly. The drive assembly drives a stirring rod to stir and mix the preservative inside the filling shell, preventing adhesion between preservative particles due to prolonged storage. The spiral blades reduce the risk of blockage at the discharge pipe caused by preservative adhesion. However, in actual use, when the spiral blades convey the preservative material in the discharge pipe, the blades compress the powdered preservative, causing it to clump again and affecting its subsequent effectiveness. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic filling device and filling method for preservative production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A crushing rod is provided on both the first and second rocker arms.

[0015] Preferably, the drive assembly further includes a first eccentric shaft disposed at the end of the drive shaft, a first connecting rod movably connected to the first eccentric shaft, a connecting rod movably connected to the end of the first connecting rod away from the first eccentric shaft and slidably connected to the sleeve, the bottom of the connecting rod being connected to the filter screen, a movable rod slidably connected inside the rotating rod and rotatably connected to the connecting rod, and a pull rope connected to the movable shaft being connected to the movable rod.

[0016] Preferably, the movable shaft includes a bearing seat fixedly connected to the elastic element and a shaft body rotatably connected to the bearing seat. The shaft body is slidably connected to the movable seat. A positioning block is fixedly provided on the inner wall of the movable groove. A track groove that cooperates with the positioning block is provided on the shaft body.

[0017] Preferably, the pneumatic loosening assembly includes a pneumatic pipe fixed to the outside of the discharge pipe, a piston movably connected inside the pneumatic pipe, the piston dividing the pneumatic pipe into an upper cavity and a lower cavity, both the upper cavity and the lower cavity are provided with air inlet valves, both the upper cavity and the lower cavity are connected to air outlet pipes, the air outlet pipes are provided with air outlet valves, the end of the air outlet pipe away from the pneumatic pipe is connected to a nozzle, and both the pneumatic pipe and the air outlet pipe are provided with a heat insulation layer on their outer sides.

[0018] Preferably, a second eccentric shaft is provided on the drive shaft, a collar is sleeved on the second eccentric shaft, a second connecting rod is fixed on the collar, and a push rod that is movably connected to the end of the second connecting rod away from the collar and slidably connected to the pneumatic tube is movably connected to the end of the second connecting rod away from the collar. The piston is fixed on the push rod.

[0019] Preferably, the nozzle includes a connecting pipe connected to the air outlet pipe and a ball head connected to the connecting pipe. The discharge pipe has a ball groove for the movement of the ball head. The ball head is rotatably connected to the ball groove by a pin. An elastic telescopic plate is fixedly connected to the bottom of the push rod. The end of the elastic telescopic plate away from the push rod is movably connected to the connecting pipe.

[0020] This invention also discloses a filling method for an automatic filling device used in preservative production, comprising the following steps:

[0021] S1: When using the equipment, the preservative to be filled is put into the tank through two inlets to store the preservative;

[0022] S2: When filling is required, control the drive motor to run. The output shaft of the drive motor drives the drive shaft to rotate. When the drive shaft rotates, the outer drive gear meshes with the driven gear on the outer side of the rotating rod, causing the rotating rod to drive the spiral conveyor blades to rotate. The spiral conveyor blades convey the preservative material accumulated between the tank and the discharge pipe downwards.

[0023] S3: When the drive shaft rotates, it drives the first eccentric shaft to rotate. The first eccentric shaft drives the connecting rod to move up and down relative to the sleeve through the first connecting rod. The connecting rod drives the moving rod to move up and down relative to the rotating rod. When the rotating rod moves up and down, it applies tension to the movable shaft intermittently through the pull rope, so that the movable shaft moves back and forth in the radial direction of the rotating rod in conjunction with the elastic element. When the movable shaft moves back and forth, it drives the first swing rod and the second swing rod to move away from each other or closer to each other. Then, when the first swing rod and the second swing rod rotate with the rotating rod, the crushing rod is used to crush the anticorrosive material conveyed downward.

[0024] The track groove on the shaft cooperates with the positioning block, so that the shaft moves in both directions when it reciprocates in the movable groove. This causes the shaft to drive the first and second swing arms to rotate with the rotating rod while rotating around the shaft, thereby improving the crushing range and crushing effect of the anti-corrosion material being conveyed.

[0025] S4: After the spiral conveyor blades convey the preservative material downwards, the material passes through the filter screen and is cut by the mesh of the filter screen. When the drive component is working, the connecting rod moves up and down, causing the filter screen to shake up and down. The shaking filter screen speeds up the cutting effect on the material.

[0026] S5: When the drive shaft rotates, it drives the second eccentric shaft to rotate. The second eccentric shaft drives the collar to rotate. The collar drives the push rod to move up and down in the pneumatic tube through the second connecting rod, so that the piston on the outside of the push rod moves up and down in the pneumatic tube. This causes the cavities on the upper and lower sides of the pneumatic tube to intermittently draw in and exhaust air. When the pneumatic tube exhausts air, it introduces air into the nozzle through the air outlet pipe. The nozzle sprays gas into the air outlet pipe. The sprayed gas mixes with the preservative material falling in the discharge pipe, causing the powdered material particles to spread rapidly, increasing the fluidity between materials, and diluting the dust particles per unit area.

[0027] As the piston slides up and down inside the pneumatic tube, heat is generated due to friction. The rising temperature inside the pneumatic tube heats the intake air. The heated air is discharged through the nozzle into the discharge pipe and exchanges heat with the preservative material being conveyed, preventing the filling material from clumping again due to moisture. The heated material is discharged from the discharge valve at the bottom of the discharge pipe and then filled.

[0028] Compared with the prior art, the present invention provides an automatic filling device and filling method for preservative production, which has the following beneficial effects:

[0029] 1. The automatic filling equipment and filling method for preservative production utilizes a conveying component to convey the preservative material downward through the discharge pipe, and uses a stirring component to crush the material during the conveying process to prevent the preservative material from sticking together due to prolonged storage or during the pushing process, thus ensuring the discharge effect of the preservative material and the subsequent filling effect.

[0030] 2. The automatic filling equipment and filling method for preservative production utilizes a track groove on the shaft that cooperates with a positioning block. This allows the shaft to move in both directions as it reciprocates within the movable groove. Simultaneously, the shaft drives the first and second swing arms to rotate around the shaft, thereby improving the crushing range and effect of the preservative material during transport. This further enhances the discharge effect of the preservative material and the subsequent filling effect.

[0031] 3. The automatic filling equipment and filling method for preservative production, when the drive component works, drives the pneumatic loosening component to work, causing the nozzle to spray gas into the air outlet pipe. The sprayed gas mixes with the preservative material falling in the discharge pipe, causing the powdered material particles to spread rapidly, increasing the fluidity between materials, diluting the dust particles per unit area, and effectively preventing the powdered preservative material from sticking together.

[0032] 4. The automatic filling equipment and filling method for preservative production utilizes the piston sliding up and down within the pneumatic tube. As the piston slides up and down, friction generates heat, which in turn heats the intake air. The heated air is then discharged through the nozzle into the discharge pipe, where it exchanges heat with the preservative material being conveyed and fed. This prevents the filled material from clumping again due to moisture, ensuring the discharge effect of the preservative material and the subsequent filling effect. Attached Figure Description

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] Example 1: Refer to Figure 1-8 An automatic filling device for preservative production includes a tank 1 with a feed inlet 101 at the top, a discharge pipe 2 connected to the bottom of the tank 1, and a discharge valve 201 at the bottom of the discharge pipe 2. The device also includes:

[0048] The material conveying and mixing mechanism is installed inside the discharge pipe 2. The material conveying and mixing mechanism includes a conveying component for conveying materials and a mixing component connected to the conveying component for mixing the materials during conveying.

[0049] The drive assembly, mounted on the discharge pipe 2, is used to drive the material conveying and mixing mechanism; and

[0050] Filter screen 3 is fixed inside the discharge pipe 2 and is used to separate the material being conveyed.

[0051] Among them, a pneumatic loosening component connected to the drive assembly is fixed on the outside of the discharge pipe 2 for diluting dust materials.

[0052] Specifically, when using the equipment, the preservative material to be filled is put into the tank 1 through two inlets 101 for storage. When filling is required, the drive component is controlled to operate, which drives the conveying and mixing mechanism and the pneumatic loosening component. The conveying component transports the preservative material in the discharge pipe 2 downwards, and the mixing component crushes the material during the conveying process to prevent the preservative material from sticking together due to long-term storage or during the pushing process. The pneumatic loosening component causes the powdered material particles to spread rapidly when discharged, increasing the fluidity between the materials and diluting the dust particles per unit area, effectively preventing the powdered preservative material from sticking together, ensuring the discharge effect of the preservative material and the subsequent filling effect.

[0053] Example 2: Refer to Figure 2 , Figure 3 , Figure 4 and Figure 9 An automatic filling device for preservative production, based on embodiment 1, further includes a conveying assembly comprising a rotating rod 4 rotatably connected to the tank 1 and the discharge pipe 2, a spiral conveying blade 401 fixed on the rod of the rotating rod 4 and the stirring assembly disposed on the rotating rod 4.

[0054] Furthermore, the drive assembly includes a support 6 fixed to the outside of the discharge pipe 2, a drive motor 601 fixed on the support 6, an output shaft of the drive motor 601 connected to a drive shaft 602, a drive gear 603 on the drive shaft 602, a driven gear 402 meshing with the drive gear 603 on the rotating rod 4, and a sleeve 7 between the rotating rod 4 and the drive shaft 602.

[0055] Specifically, when filling is required, the drive motor 601 is controlled to run. The output shaft of the drive motor 601 drives the drive shaft 602 to rotate. When the drive shaft 602 rotates, the outer drive gear 603 meshes with the driven gear 402 on the outer side of the rotating rod 4, causing the rotating rod 4 to drive the spiral conveying blade 401 to rotate. The spiral conveying blade 401 conveys the preservative material accumulated between the tank 1 and the discharge pipe 2 downwards and gradually discharges it out of the discharge pipe 2, thereby completing the discharge and filling of the preservative. This avoids blockage due to the diameter of the discharge pipe 2 being smaller than that of the tank 1, and at the same time ensures the discharge effect of the preservative by the filling equipment.

[0056] Example 3: Reference Figure 2-9An automatic filling device for preservative production, based on embodiment 2, further includes a stirring assembly comprising a movable shaft 5 movably connected within a rotating rod 4. A movable groove 403 for the movable shaft 5 is provided on the rotating rod 4. An elastic element 4031 is provided between the inner wall of the movable groove 403 and the movable shaft 5. First rocker arms 10 are provided on both sides of the end of the movable shaft 5. A movable seat 11 is movably connected to the rotating rod 4. Second rocker arms 111 are movably connected to both sides of the movable seat 11. The end of the second rocker arm 111 away from the movable seat 11 is rotatably connected to the end of the first rocker arm 10 away from the movable shaft 5. A crushing rod 12 is provided on both the first rocker arm 10 and the second rocker arm 111.

[0057] Furthermore, the drive assembly also includes a first eccentric shaft 8 disposed at the end of the drive shaft 602, a first connecting rod 801 movably connected to the first eccentric shaft 8, a connecting rod 802 movably connected to the sleeve 7 at the end of the first connecting rod 801 away from the first eccentric shaft 8, the bottom of the connecting rod 802 being connected to the filter screen 3, a movable rod 9 movably connected to the connecting rod 802 being rotatably connected inside the rotating rod 4, and a pull rope 901 connected to the movable shaft 5 being connected to the movable rod 9.

[0058] Specifically, when the drive shaft 602 of the drive assembly rotates, it drives the first eccentric shaft 8 to rotate. The first eccentric shaft 8 drives the connecting rod 802 to move up and down relative to the sleeve 7 via the first connecting rod 801. The connecting rod 802 drives the moving rod 9 to move up and down relative to the rotating rod 4. When the rotating rod 4 moves up and down, it intermittently applies tension to the movable shaft 5 through the pull rope 901, causing the movable shaft 5 to move back and forth radially in conjunction with the elastic element 4031 on the rotating rod 4. When the movable shaft 5 moves back and forth, it drives the first swing rod 10 and the second swing rod 11. 1. When the first swing arm 10 and the second swing arm 111 rotate with the rotating rod 4, the crushing rod 12 crushes the downward-conveyed preservative material. After the spiral conveying blade 401 conveys the preservative material downward, the material passes through the filter screen 3 and is cut by the mesh of the filter screen 3. When the drive component is working, the connecting rod 802 moves up and down, causing the filter screen 3 to shake up and down. The shaking filter screen 3 accelerates the cutting effect of the material, further improving the discharge effect of the preservative material and the subsequent filling effect.

[0059] Example 4: Reference Figure 6-7 An automatic filling device for preservative production, based on embodiment 3, further includes a movable shaft 5 comprising a shaft seat 501 fixedly connected to an elastic element 4031 and a shaft body 502 rotatably connected to the shaft seat 501. The shaft body 502 is slidably connected to the movable seat 11. A positioning block 4032 is fixedly provided on the inner wall of the movable groove 403. A track groove 5021 that cooperates with the positioning block 4032 is provided on the shaft body 502.

[0060] Specifically, when the movable shaft 5 moves within the movable groove 403, the track groove 5021 on the shaft 502 cooperates with the positioning block 4032, causing the shaft 502 to move in both directions as it reciprocates within the movable groove 403. This causes the shaft 502 to drive the first swing arm 10 and the second swing arm 111 to rotate with the rotating rod 4 while rotating around the shaft 502 as the center, thereby improving the crushing range and crushing effect of the preservative material during conveying, further improving the discharge effect of the preservative material and the subsequent filling effect.

[0061] Example 5: Refer to Figure 3 , Figure 5 , Figure 9 , Figure 10 and Figure 11 An automatic filling device for preservative production, based on embodiment 4, further includes a pneumatic loosening component comprising a pneumatic pipe 13 fixed to the outside of the discharge pipe 2, a piston 131 movably connected inside the pneumatic pipe 13, the piston 131 dividing the pneumatic pipe 13 into an upper cavity and a lower cavity, both the upper cavity and the lower cavity being provided with an air inlet valve 132, both the upper cavity and the lower cavity being connected with an air outlet pipe 133, an air outlet valve being provided inside the air outlet pipe 133, a nozzle 14 being connected to the end of the air outlet pipe 133 away from the pneumatic pipe 13, and both the pneumatic pipe 13 and the air outlet pipe 133 being provided with a heat insulation layer on the outside.

[0062] Furthermore, a second eccentric shaft 15 is provided on the drive shaft 602, a collar 151 is sleeved on the second eccentric shaft 15, a second connecting rod 152 is fixed on the collar 151, and a push rod 153 that is movably connected to the pneumatic tube 13 is slidably connected to the end of the second connecting rod 152 away from the collar 151. The piston 131 is fixed on the push rod 153.

[0063] Specifically, when the drive shaft 602 of the drive assembly rotates, it drives the second eccentric shaft 15 to rotate. The second eccentric shaft 15 drives the collar 151 to rotate. The collar 151 drives the push rod 153 to move up and down in the pneumatic tube 13 through the second connecting rod 152. This causes the piston 131 on the outside of the push rod 153 to move up and down in the pneumatic tube 13, causing the cavities on the upper and lower sides of the pneumatic tube 13 to intermittently draw in and exhaust air. When the pneumatic tube 13 exhausts air, it introduces air into the nozzle 14 through the air outlet pipe 133. The nozzle 14 sprays gas into the air outlet pipe 133. The sprayed gas mixes with the preservative material falling in the discharge pipe 2, making it into powder. The material particles diffuse rapidly, increasing the fluidity between materials and diluting the dust particles per unit area; and when the piston 131 slides up and down in the pneumatic tube 13, heat is generated due to friction. The insulation layer on the outside of the pneumatic tube 13 and the air outlet 133 prevents heat loss. The rising temperature inside the pneumatic tube 13 heats the intake air. The heated air is discharged into the discharge pipe 2 through the nozzle 14 and exchanges heat with the preservative material in the conveying and feeding process, so that the filled material will not clump again due to moisture, effectively preventing the powdery preservative material from sticking together.

[0064] Example 6: Refer to Figure 5 , Figure 10 and Figure 11 An automatic filling device for preservative production, based on embodiment 5, further includes a nozzle 14 comprising a connecting pipe 141 connected to an air outlet pipe 133 and a ball head 142 connected to the connecting pipe 141. A ball groove for the movement of the ball head 142 is provided on the discharge pipe 2. The ball head 142 is rotatably connected to the ball groove by a pin. An elastic telescopic plate 16 is fixedly connected to the bottom of the push rod 153. The end of the elastic telescopic plate 16 away from the push rod 153 is movably connected to the connecting pipe 141.

[0065] Specifically, when the push rod 153 drives the piston 131 to move up and down reciprocally, the push rod 153 will simultaneously drive the elastic telescopic plate 16 to move upward. The elastic telescopic plate 16 is stretched and drives the connecting pipe 141 to swing, so that the ball head 142 at the end of the connecting pipe 141 rotates around the pin connected to the ball groove, thereby adjusting the air discharge angle of the ball head 142, so that the hot air heats the preservative material evenly and evenly, so that the filled material will not clump again due to moisture, and effectively avoids the adhesion between the powdery preservative materials.

[0066] This invention also discloses a filling method for an automatic filling device used in preservative production, comprising the following steps:

[0067] S1: When using the equipment, the preservative to be filled is put into the tank 1 through the two inlets 101 to store the preservative;

[0068] S2: When filling is required, control the drive motor 601 to run. The output shaft of the drive motor 601 drives the drive shaft 602 to rotate. When the drive shaft 602 rotates, the outer drive gear 603 meshes with the outer driven gear 402 of the rotating rod 4, causing the rotating rod 4 to drive the spiral conveying blade 401 to rotate. The spiral conveying blade 401 conveys the preservative material accumulated between the tank 1 and the discharge pipe 2 downwards.

[0069] S3: When the drive shaft 602 rotates, it drives the first eccentric shaft 8 to rotate. The first eccentric shaft 8 drives the connecting rod 802 to move up and down relative to the sleeve 7 through the first connecting rod 801. The connecting rod 802 drives the moving rod 9 to move up and down relative to the rotating rod 4. When the rotating rod 4 moves up and down, it applies intermittent tension to the movable shaft 5 through the pull rope 901, so that the movable shaft 5 moves back and forth in the radial direction of the rotating rod 4 in conjunction with the elastic element 4031. When the movable shaft 5 moves back and forth, it drives the first swing rod 10 and the second swing rod 111 to move away from or closer to each other. Then, when the first swing rod 10 and the second swing rod 111 rotate with the rotating rod 4, the crushing rod 12 crushes the downward conveyed preservative material.

[0070] The track groove 5021 on the shaft 502 cooperates with the positioning block 4032, so that the shaft 502 moves forward and backward when it reciprocates in the movable groove 403. This causes the shaft 502 to drive the first swing rod 10 and the second swing rod 111 to rotate with the rotating rod 4 while rotating around the shaft 502, thereby improving the crushing range and crushing effect of the anticorrosive material during conveying.

[0071] S4: After the spiral conveyor blades 401 convey the preservative material downwards, the material passes through the filter screen 3 and is cut by the mesh of the filter screen 3. When the drive component is working, the connecting rod 802 moves up and down, causing the filter screen 3 to shake up and down. The shaking filter screen 3 accelerates the cutting effect on the material.

[0072] S5: When the drive shaft 602 rotates, it drives the second eccentric shaft 15 to rotate. The second eccentric shaft 15 drives the collar 151 to rotate. The collar 151 drives the push rod 153 to move up and down in the pneumatic tube 13 through the second connecting rod 152. This causes the piston 131 on the outside of the push rod 153 to move up and down in the pneumatic tube 13, causing the cavities on the upper and lower sides of the pneumatic tube 13 to intermittently draw and exhaust air. When the pneumatic tube 13 exhausts air, it introduces air into the nozzle 14 through the air outlet pipe 133. The nozzle 14 sprays gas into the air outlet pipe 133. The sprayed gas mixes with the preservative material falling in the discharge pipe 2, causing the powdered material particles to spread rapidly, increasing the fluidity between materials, and diluting the dust particles per unit area.

[0073] When the piston 131 slides up and down in the pneumatic tube 13, heat is generated due to friction. The rising temperature in the pneumatic tube 13 heats the intake air. The heated air is discharged into the discharge pipe 2 through the nozzle 14 and exchanges heat with the preservative material in the conveying process, so that the filling material will not clump again due to moisture. The broken and heated material is discharged from the discharge valve 201 at the bottom of the discharge pipe 2 and filled.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The bottom of the push rod (153) is fixedly connected to an elastic telescopic plate (16). The end of the elastic telescopic plate (16) away from the push rod (153) is movably connected to the connecting pipe (141).

7. A filling method based on the automatic filling equipment for preservative production as described in claim 6, characterized in that, Includes the following steps: S1: When using the equipment, the preservative to be filled is put into the tank (1) through two feed ports (101) to store the preservative; S2: When filling is required, control the drive motor (601) to run. The output shaft of the drive motor (601) drives the drive shaft (602) to rotate. When the drive shaft (602) rotates, the outer drive gear (603) meshes with the driven gear (402) on the outer side of the rotating rod (4), so that the rotating rod (4) drives the spiral conveying blade (401) to rotate. The spiral conveying blade (401) conveys the preservative material accumulated between the tank (1) and the discharge pipe (2) downwards. S3: When the drive shaft (602) rotates, it drives the first eccentric shaft (8) to rotate. The first eccentric shaft (8) drives the connecting rod (802) to move up and down relative to the sleeve (7) through the first connecting rod (801). The connecting rod (802) drives the moving rod (9) to move up and down relative to the rotating rod (4). When the rotating rod (4) moves up and down, it applies tension to the movable shaft (5) intermittently through the pull rope (901), so that the movable shaft (5) moves back and forth in the radial direction of the rotating rod (4) in conjunction with the elastic element (4031). When the movable shaft (5) moves back and forth, it drives the first swing rod (10) and the second swing rod (111) to move away from or closer to each other. Then, when the first swing rod (10) and the second swing rod (111) rotate with the rotating rod (4), the crushing rod (12) crushes the downward conveyed preservative material. The track groove (5021) on the shaft (502) cooperates with the positioning block (4032) so that the shaft (502) moves forward and backward in the movable groove (403) when it moves back and forth, so that the shaft (502) drives the first swing rod (10) and the second swing rod (111) to rotate with the rotating rod (4) while rotating around the shaft (502) as the center; S4: The spiral conveyor blade (401) conveys the preservative material downwards. The material passes through the filter screen (3) and is cut by the mesh of the filter screen (3). When the drive component is working, the connecting rod (802) moves up and down, causing the filter screen (3) to shake up and down. S5: When the drive shaft (602) rotates, it drives the second eccentric shaft (15) to rotate. The second eccentric shaft (15) drives the collar (151) to rotate. The collar (151) drives the push rod (153) to move up and down in the pneumatic tube (13) through the second connecting rod (152). This causes the piston (131) on the outside of the push rod (153) to move up and down in the pneumatic tube (13), causing the cavities on the upper and lower sides of the pneumatic tube (13) to intermittently draw and exhaust air. When the pneumatic tube (13) exhausts air, it introduces air into the nozzle (14) through the air outlet pipe (133). The nozzle (14) sprays gas into the air outlet pipe (133). The sprayed gas mixes with the preservative material falling in the discharge pipe (2), causing the powdered material particles to spread rapidly, increasing the fluidity between materials, and diluting the dust particles in a unit area. When the piston (131) slides up and down in the pneumatic tube (13), heat is generated due to friction. The temperature rise in the pneumatic tube (13) heats the air that is drawn in. The heated air is discharged into the discharge pipe (2) through the nozzle (14) and then exchanges heat with the preservative material in the conveying process, so that the filling material will not clump again due to moisture. The broken and heated material is discharged from the discharge valve (201) at the bottom of the discharge pipe (2) and filled.
